In its recent statement 'Sex Selection and Preimplantation Genetic Diagnosis', the Ethics Committee of the American Society of Reproductive Medicine concluded that preimplantation genetic diagnosis for sex selection for non-medical reasons should be discouraged because it poses a risk of unwarranted gender bias, social harm, and results in the diversion of medical resources from genuine medical need. We critically examine the arguments presented against sex selection using preimplantation genetic diagnosis. We argue that sex selection should be (...) available, at least within privately funded health care. (shrink)

When widespread use of sex‐selective abortion and sex selection through assisted reproduction lead to severe harms to third parties and perpetuate discrimination, should these practices be banned? In this paper I focus on India and show why a common argument for a ban on sex selection fails even in these circumstances. I set aside a common objection to the argument, namely that women have a right to procreative autonomy that trumps the state's interest in protecting other parties from (...) harm, and argue against the ban on consequentialist grounds. I perform a pairwise comparative analysis of sex selection and its plausible alternatives and argue that that the ban fails to improve the state of affairs relative to a scenario without a ban. The ban makes the situation worse, especially for mothers and their daughters. India should therefore repeal its ban on sex selection. (shrink)

BACKGROUND: -/- Preconception sex selection for non-medical reasons raises serious moral, legal and social issues. The main concern is based on the assumption that a freely available service for sex selection will distort the natural sex ratio and lead to a severe gender imbalance. However, for a severe gender imbalance to happen, at least two conditions have to be met. First, there must be a significant preference for children of a particular sex, and second, there must be a (...) considerable demand for preconception sex selection. To ascertain whether or not these two conditions are met, we have conducted a survey in Germany. METHODS: -/- As a representative sample of the German population, 1094 men and women aged 18-45 years were asked about their gender preferences and whether or not they could imagine selecting the sex of their children through flow cytometric separation of X- and Y-bearing sperm followed by intrauterine insemination. RESULTS: -/- 58% of respondents stated that they do not care about the sex of their offspring. 30% wish to have a family with an equal number of boys and girls. 4% would like to have more boys than girls, 3% more girls than boys, 1% only boys and 1% only girls. For first-borns, however, there is still a preference for boys over girls. While 75.6% claimed to have no gender preference, 14.2% would like their first child to be a boy and 10.1% would like their first child to be a girl. Whereas 6% could imagine taking advantage of preconception sex selection, 92% found this to be out of the question. Even in the hypothetical case that a medication for sex selection were ever to become available, 90% stated that they would not want to use it. CONCLUSION: -/- Given that a majority does not seem to care about the sex of their offspring and only a minority seem to be willing to select the sex of their children, a freely available service for preconception sex selection for non-medical reasons is rather unlikely to cause a severe gender imbalance in Germany.

Preconception sex selection for nonmedical reasons raises important moral, legal, and social issues. The main concern is based upon the assumption that a widely available service for sex selection will lead to a socially disruptive imbalance of the sexes. For a severe sex ratio distortion to occur, however, at least two conditions have to be met. First, there must be a significant preference for children of a particular sex, and second, there must be a considerable interest in employing (...) sex selection technology. Our objective was to ascertain such demand and preferences among the United States general population. (shrink)

Given that sex selection does not harm anyone, there is no moral justification for a legal ban.

The aim of this survey was to explore the attitudes towards gender selection, focusing on people who were affected by infertility and also familiar with advanced technologies such as the internet. Although this survey is based almost exclusively on answers from women, it seems reasonable to conclude that a widely available service for preconception sex selection for non-medical reasons would not cause a severe gender imbalance in Germany.

Within the next parliamentary term, the German government is expected to replace the current Embryo Protection Act with a new Human Reproductive Technology Act. Before introducing new legislation, policy makers may want to survey public attitudes towards novel applications of reproductive technology. In order to assess opinions and concerns about preconception sex selection for non-medical reasons, a social survey has been conducted in Germany. As a representative sample of the German population, 1005 men and women 18 years and older (...) were asked whether or not preconception sex selection should be made available. Of the respondents, 32% held that sex selection should be strictly prohibited, be it for medical or non-medical reasons, and 54% accepted the use of preconception sex selection for medical purposes. Only a minority of 11% approved of the use of preconception sex selection for non-medical reasons. The widespread opposition to a freely available service for non-medical sex selection is based on several claims: 87% of respondents hold that 'children are a gift and deserve to be loved regardless of any characteristics such as beauty, intelligence or sex'; 79% argue that choosing the sex of children is 'playing God'; 76% are opposed because it is seen as 'unnatural'; 49% are afraid that it is 'skewing the natural sex ratio'; and 40% consider it to be 'sexist'.

The Sorting Society: The Ethics of Genetic Screening and Therapy. Edited by Loane Skene & Janna Thompson, Cambridge University Press, Cambridge 2008.

Preconception sex selection for non-medical reasons raises serious moral, legal and social issues. The main concerns include the threat of a sex ratio distortion due to a common preference for boys over girls, the charge of sexism, the danger of reinforcing gender stereotypical behaviour in sex selected children, and the fear of a slippery slope towards creating designer babies. This paper endeavours to show that none of the objections to preconception sex selection is conclusive and that there is (...) no justification for denying parents the right to choose the sex of their prospective children.

After its review of the Human Fertilization and Embryology Act of 1990, the Department of Health concluded that the British Parliament ought to outlaw sex selection for any but the most serious of medical reasons. This paper reviews the most frequently expressed objections to social sex selection and concludes that there is simply no moral justification for prohibiting parents from using sex selection technology to balance their families.

BACKGROUND Preconception sex selection for non-medical reasons is a controversial issue in bioethics. Little research has described preferences for preconception sex selection among Arab populations. This study describes the sex preference and interest in employing sex selection techniques among pregnant women in northern Jordan. -/- METHODS A self-reported questionnaire was administered to 600 pregnant women in Irbid, Jordan. χ2 test and binary logistic regression were used to examine the factors associated with interest in preconception sex selection. (...) -/- RESULTS In general, the interest in using sex selection was low. Women who preferred boys were more likely to be interested in sex selection, if paid for by the couple [odds ratio (OR) = 4.40, 95% confidence interval (CI): 1.75–11.11] or by health insurance (OR = 3.42, 95% CI: 1.94–6.06), or, if feasible, administered through oral medication (OR = 8.84, 95% CI: 5.05–15.63). Women with lower education were more likely to be interested in sex selection, if paid by health insurance (OR = 1.96, 95% CI: 1.10–3.45) and were more likely to believe that sex selection is legal (OR = 1.79, 95% CI: 1.06–2.86). Women who had no boys were more likely to be interested in sex selection, if paid by health insurance (OR = 1.94, 95% CI: 1.10–3.42) or, if feasible, through medication (OR = 3.03, 95% CI: 1.82–5.00). -/- CONCLUSIONS The majority of participants were not in favor of using preconception sex selection. Those with a preference to have boys, with lower education, and those with an imbalanced family were more likely to be interested in using sex selection technology. (shrink)

BACKGROUND: -/- In its recent report 'Human Reproductive Technologies and the Law', the House of Commons' Select Committee on Science and Technology called for greater efforts to establish the potential demographic impact of sex selection across all sectors of UK society. Given the well-known preference for boys over girls among some communities, there is concern that a readily available service for social sex selection may upset the balance of the sexes. Of particular interest are the gender preferences and (...) the demand for sex selection among Pakistanis. METHODS: -/- We conducted a social survey on gender preferences and potential demand for preconception sex selection among 301 pregnant women in Karachi, Pakistan, using a self-report questionnaire consisting of 14 questions. RESULTS: -/- About 41.5% wish to have a family with an equal number of boys and girls; 3.3% would like to have only boys, 1.0% only girls, 27.6% more boys than girls and 4.3% more girls than boys, and 22.3% stated that they do not care about the sex composition of their family. Whereas 6.3% could imagine employing cytometric sperm separation for social sex selection, 76.1% could not and 17.6% were undecided. About 27.2% felt that social sex selection ought to be legal, 48.8% thought it ought to be illegal and 23.9% were undecided. CONCLUSIONS: -/- Although Pakistani women do show a statistically significant preference for boys over girls, the number of women willing to subject themselves to cytometric sperm separation appears to be too small to cause a severe imbalance of the sexes. However, further research among British citizens of Pakistani origin is needed to establish whether sex selection poses a serious threat to the sex ratio of UK communities. (shrink)

Much has been written about the ethics of sex selection. This article thoroughly explores the ethical arguments put forth in the literature both for and against non-medical sex selection using sperm sorting. While most of these arguments come from philosophers, feminist scholars, social scientists and members of the healthcare community, they are often echoed in empirical studies that have explored community values. This review is timely because the first efficacious method for sex selection via sperm sorting, MicroSort, (...) is currently in clinical trials and moving closer to FDA approval for marketing in the USA. While the clinical trials are currently focused on the use of MicroSort to avoid X-linked genetic diseases, MicroSort can also be used to satisfy parental preferences. (shrink)

The majority of German specialists in reproductive medicine opposes preimplantation sex selection for nonmedical reasons while recommending preimplantation sex selection for medical reasons, e.g. X-linked diseases like haemophilia.

This brief paper summarizes a series of postal investigations on the acceptance of selection for X or Y spermatozoa. These were conducted mainly in Germany but also in the UK, the Netherlands and the US. Selected families were approached with a series of questions about their wish to use sperm selection, and their choice of boys or girls. In general, large majorities opposed this approach for family balancing or sex selection on the basis of cost and inconvenience (...) of the treatment. The view was expressed that its use in medicine was more acceptable. Care was taken to compose a series of open questions to particular sections of the population, e.g.men versus women, differing ages, and families with imbalanced sex ratios. More favourable responses arose, for example in pregnant women. Overall, all four nations had large majorities against the use of sex selection. (shrink)

Jeremy Williams has argued that if we are committed to a liberal pro-choice stance with regard to selective abortion for disability, we will be unable to justify the prohibition of sex selective abortion. Here, I apply his reasoning to selective abortion based on other traits pregnant women may decide are undesirable. These include susceptibility to disease, level of intelligence, physical appearance, sexual orientation, religious belief and criminality—in fact any traits attributable to some degree to a genetic component. Firstly, I review (...) Williams’ argument, which claims that if a woman is granted the right to abort based on fetal impairment, then by parity of reasoning she should also be granted the right to choose sex selective abortion. I show that these same considerations that entail the permissibility of sex selective abortion are also applicable to genetic selection abortion. I then examine the objections to sex selective abortion that Williams considers and rejects, and show that they also lack force against genetic selection abortion. Finally, I consider some additional objections that might be raised, and conclude that a liberal pro-choice stance on selective abortion for disability entails the permissibility of selective abortion for most genetic traits.

Browne 1 (this issue ) argues that what may appear to be a benevolent practice-disclosing the sex of a fetus to expecting parents who wish to know-is in fact an epistemically problematic and, as a result, ethically questionable medical practice. Browne worries that not only will the disclosure of fetal sex encourage sex-selective abortions (an issue we will not take up here), but also that it will convey a misleading and pernicious message about the relationship between sex and gender. More (...) specifically, she contends that the practice of disclosure is problematic because (1) it purports to establish the gender of the developing baby based on information about the baby's sex, whereas this is not a warranted inference because while sex is determined by biological factors, gender is determined by social factors and (2) it conflates (biological) sex with (social) gender or encourages such conflation or reduction and thereby promotes 'essentialistic' thinking about gender that is closely linked to sexism and social injustice. If (1) is true, then disclosing fetal sex amounts to misinforming or misleading prospective parents-and since misinforming patients is wrong, the act of disclosing is also wrong. However, beyond the wrongs of misinforming patients, the practice also perpetuates the harms associated with a rigidly gendered society through endorsing the message in (2), thus lending the authority of the medical profession to the gender-essentialist ideas that have underpinned, and continue to drive, sexism and social injustice. This analysis leads Browne to recommend that clinicians be prohibited from informing parents about the sex of their developing fetus. -/- We agree with Browne that gender essentialism-the notion that 'femaleness' and 'maleness' carve out distinct natural classes with innate, immutable properties-is not only a false metaphysical thesis, but also a pernicious idea insofar as the sexist attitudes it fosters motivate policies that systematically violate the human rights of women, as well as those of the LGBTQ community. However, we do not think that the disclosure of fetal sex misinforms prospective parents about the gender of their baby, nor do we believe that such disclosure presupposes or promotes gender essentialism properly understood.

What is it for an animal to be female, or male? An emerging consensus among philosophers of biology is that sex is grounded in some manner or another on anisogamy, that is, the ability to produce either large gametes (egg) or small gametes (sperm), though the exact nature of this grounding remains contentious. Here we argue for a new conception of this relation. In our view, one’s sex doesn’t depend on the kind of gamete one is capable of making, but (...) on the kind of gamete one is designed to make, where design is understood in terms of an evolutionary or ontogenetic selection process. Specifically, we argue that what it is to be, say, male, is to have a part or process that has the (proximal or distal) biological function of producing sperm. We outline and defend our view, and sketch some implications for scientific and social problems related to sex. (shrink)

The study investigated assessment of sex and age impersonation as academic dishonest behaviour among post graduate students’ of Federal Universities of South-South, Nigeria. The study which is a survey research, involved a multi-stage stratified random sampling technique of 440 males and 490 females from 3 universities and 3 faculties of the same universities in South-South, Nigeria. Sample was selected through stratified random sampling approach. The study adopted frequencies, percentages, factor analysis and multiple classification analysis statistical tools. A questionnaire developed and (...) validated by the researcher titled: “Academic Dishonest Behaviour Questionnaire’’ (ADBQ) with Cronbach coefficient alpha reliability of 0.83 was used for data collection. Two research questions and one hypothesis were formulated for the study. The findings indicated that the students used for this study were involved in Sex and Age impersonation aspect of academic dishonest behaviours. Female students were seen to be more involved than male in impersonation, Students ages 25-29years are more culpable in impersonation as academic dishonest behaviour. It is therefore recommended among others that there should be synergy among stakeholders in the educational process to fight this art of impersonation. (shrink)

This paper explores two separate elements of sex, namely sexual selection and crossover. A simple computerised genetic algorithm can confirm a possible connection between sexual selection and the elimination of copying errors.

This study examined adolescents’ perception management and attitudes towards sex education in secondary schools in Cross River State, Nigeria. The study was guided by three null hypotheses that were formulated. The study adopted a descriptive survey design. Purposive sampling technique was employed by the researchers in selecting a sample of 1,080 students from a population of 98,915 secondary school students distributed across 271 public secondary schools in Cross River State. Adolescents Perception Management and Attitudes towards Sex Education Questionnaire (APMATSEQ) was (...) used as an instrument for data collection. The null hypotheses were all tested at .05 level of significance using Pearson product moment correlation and multiple regression analyses. Findings from the study revealed that adolescents' counseling and sensitization are significantly related to their attitudes towards sex education respectively and jointly; both variables accounted for 50.3 percent (R2 = .503, Adj. R2 = .502) of the total variance of adolescents’ attitudes towards sex education. Findings also revealed that adolescents’ counselling and sensitization have a significant composite influence (F = 544.924, p < .05) on their attitudes towards sex education, with adolescents’ counselling being the highest predictor (β = .499, t = 19.392), followed by adolescents’ sensitization (β = .299, t = 11.632). Based on the findings, it was recommended amongst others that; professional counselors should be employed by the government to enable secondary schools to have at least three counselors per school in order for schools to effectively manage students’ perception.

Gender/sex divide has always been the part and parcel of any discourse. The problematics of identity is built around male as superior and female as inferior beings. The changing scenario of the universe defines human beings in terms of neoliberalism, globalization, deconstruction of ideas and images, and, above all the way of interpreting everything from a post-structuralist approach has brought forth new ideas and images in the rubric of discourse analysis. Body and physical fitness have always been an issue of (...) debate and discussion since it engages an arena of women’s participation in various physical fitness activities and games. The present paper attempts to focus on the world of games and sports as a site where established values about gender have been contested, resisted, negotiated and transformed through the analysis of selected films. Popular culture has always been a powerful medium to challenge the myth that strong and powerful women are not real. The paper will attempt to take up this terrain to focus on women engaged in the world of games and sports to show the present scenario of women’s games and sports in the Indian context.

Discussions of the implications of sexual reproduction have appeared throughout the history of evolutionary biology, from Darwin to Weismann, Fisher, Muller, Maynard Smith, and Williams. The latest of these appearances highlighted an evolutionary paradox that had previously been overlooked. In many animal and plant species reproduction is obligately sexual and also half the offspring are male, yet the males contribute nothing but genes to reproduction. If asexual mutants of such a species were to produce as many asexual offspring on average (...) as sexual females in that species produce daughters and sons, the growth rate of their population would be twice as large. Whereas half the offspring of sexual females are noncontributory males, all the offspring of such an asexual mutant would contribute to growth rate. Nevertheless, sexual reproduction prevails in most species and is not lost evolutionarily. (shrink)

It is commonly assumed that personalization technologies used by Google for the purpose of tailoring search results for individual users create filter bubbles, which reinforce users’ political views. Surprisingly, empirical evidence for a personalization-induced filter bubble has not been forthcoming. Here, we investigate whether filter bubbles may result instead from a searcher’s choice of search queries. In the first experiment, participants rated the left-right leaning of 48 queries (search strings), 6 for each of 8 topics (abortion, benefits, climate change, sex (...) equality, immigration, nuclear family, Islam, and taxation). An independent sample of participants were then asked to select one of these queries for each of the 8 topics. With the exception of the topic of Islam, participants were significantly more likely to select a query corresponding to their own political leaning, compared to other queries, explaining between 12% and 39% of the variance. A second experiment investigated the effect of the political leaning of the same queries on the overall political leaning of Search Engine Result Pages (SERPs) in Google Search. The top six results of each SERP were rated collectively by a third group of participants, explaining 36.3% of the variance across all 48 search terms (p < .00001). That is, (1) participants in our experiments tended to select own-side search queries, and (2) using those queries tended to yield own-side search results when using the Google search engine. Our results are consistent with the notion of a self-imposed filter bubble in which query selection plays a salient role. (shrink)

Mitochondrial DNA (mtDNA) diseases are a group of neuromuscular diseases that often cause suffering and premature death. New mitochondrial replacement techniques (MRTs) may offer women with mtDNA diseases the opportunity to have healthy offspring to whom they are genetically related. MRTs will likely be ready to license for clinical use in the near future and a discussion of the ethics of the clinical introduction ofMRTs is needed. This paper begins by evaluating three concerns about the safety of MRTs for clinical (...) use on humans: (1) Is it ethical to use MRTs if safe alternatives exist? (2) Would persons with three genetic contributors be at risk of suffering? and (3) Can society trust that MRTs will be made available for humans only once adequate safety testing has taken place, and that MRTs will only be licensed for clinical use in a way that minimises risks? It is then argued that the ethics debate about MRTs should be reoriented towards recommendingways to reduce the possible risks of MRT use on humans. Two recommendations are made: (1) licensed clinical access to MRTs should only be granted to prospective parents if they intend to tell their children about their MRT conception by adulthood; and (2) sex selection should be used in conjunction with the clinical use ofMRTs, in order to reduce transgenerational health risks.

What explains the distinctive features of human behavior? In this book, Stewart-Williams aims to answer this ambitious question. This book is an engaging addition to the already long list of recent attempts to provide an evolutionary explanation of human uniqueness. It is organized into six chapters, plus two appendices. These chapters address several key topics in evolutionary theory, sex differences and sexual behavior, altruism, and cultural evolution, albeit with varying degrees of detail and depth. These topics include sexual selection, (...) kin selection, Hamilton’s rule, reciprocal altruism, costly signaling theory, group selection, gene-centered views of evolution, inclusive fitness, proximate and ultimate evolutionary explanations, inbreeding avoidance, the Westermarck effect, jealousy, sperm competition, mating and parenting effort, cumulative cultural evolution, imitation and learning biases, evolutionary mismatch theories, and more.

This article points out: “The combination of men and women in families is irrational.” Men and women are two different “species.” They only require sexual activities from each other, which are considered the less time-consuming activities during their lives. Sex must be treated as an enemy of marriage, due to its inferior and treacherous nature, and should not be included in marriage. Men and women should not live together in a family, since this institution must be understood as a permanent (...) place for all family members and is expected to have a solid structure. The traditional family model is the result of men‟s enslavement of women and the exaggeration of the role of sex. This model creates an overwhelming advantage for men in selecting partners, proposing marriage, and other family activities. This article indicates: (i) The prominent family models existing between the group-marriage period and now are sex-based family models. (ii) Technical and social conditions nowadays require a new and sustainable base for a family. The selected targets in this study are the consanguineous and sworn relationships among same-sex people in case they choose to be heterosexual, (and in turn, among opposite-sex persons when they engage in homosexuality). For example, a family can consist of two blood brothers (or sworn brothers or cousins) with their children, in case they are heterosexual. This family model is named the non-sex based family (NSBF) model, since the sexual needs will be met outside the family. The article also outlines a post-patriarchal society with the presence of NSBFs, and argues that the new model should be seen as an essential development trend of society. (shrink)

Turing’s much debated test has turned 70 and is still fairly controversial. His 1950 paper is seen as a complex and multilayered text, and key questions about it remain largely unanswered. Why did Turing select learning from experience as the best approach to achieve machine intelligence? Why did he spend several years working with chess playing as a task to illustrate and test for machine intelligence only to trade it out for conversational question-answering in 1950? Why did Turing refer to (...) gender imitation in a test for machine intelligence? In this article, I shall address these questions by unveiling social, historical and epistemological roots of the so-called Turing test. I will draw attention to a historical fact that has been only scarcely observed in the secondary literature thus far, namely that Turing’s 1950 test emerged out of a controversy over the cognitive capabilities of digital computers, most notably out of debates with physicist and computer pioneer Douglas Hartree, chemist and philosopher Michael Polanyi, and neurosurgeon Geoffrey Jefferson. Seen in its historical context, Turing’s 1950 paper can be understood as essentially a reply to a series of challenges posed to him by these thinkers arguing against his view that machines can think. Turing did propose gender learning and imitation as one of his various imitation tests for machine intelligence, and I argue here that this was done in response to Jefferson's suggestion that gendered behavior is causally related to the physiology of sex hormones.

During the last few years, burnout has gained more and more attention for its strong connection with job performance, absenteeism, and presenteeism. It is a psychological phenomenon that depends on occupation, also presenting differences between sexes. However, to properly compare the burnout levels of different groups, a psychometric instrument with adequate validity evidence should be selected (i.e., with measurement invariance). This paper aims to describe the psychometric properties of the Oldenburg Burnout Inventory (OLBI) version adapted for workers from Brazil and (...) Portugal, and to compare burnout across countries and sexes. OLBI's validity evidence based on the internal structure (dimensionality, reliability, and measurement invariance), and validity evidence based on relationships with other variables (work engagement) are described. Additionally, it aims presents a revision of different OLBI's versions—since this is the first version of the instrument developed simultaneously for both countries—it is an important instrument for understanding burnout between sexes in organizations. Data were used from 1,172 employees across two independent samples, one from Portugal and the other from Brazil, 65 percent being female. Regarding the OLBI internal structure, a reduced version (15 items) was obtained. The high correlation between disengagement and exhaustion, suggested the existence of a second-order latent factor, burnout, which presented measurement invariance for country and sex. Confirmatory factor analysis of the Portuguese OLBI version presented good goodness-of-fit indices and good internal consistency values. No statistically significant differences were found in burnout between sexes or countries. OLBI also showed psychometric properties that make it a promising and freely available instrument to measure and compare burnout levels of Portuguese and Brazilian employees. (shrink)

Quarantines and virtual learning became necessary as a result of the COVID-19 pandemic. This study investigates the challenges and opportunities in virtual classes; and how they affect the academic goals. There were 150 secondary students from Junior and Senior High School levels of education in the Philippines, who were deliberately selected; and they participated in the quantitative online survey that used a 62-item self-made 4-point Likert scale questionnaire, with 0.81 reliability coefficients. The data were evaluated by means of the percentage, (...) the mean, and the standard deviation. Sex and secondary education levels were used, in order to compare the students’ challenges and opportunities. One-way ANOVA compared the male and female respondents’ perceived challenges and opportunities. The results revealed that junior high-school (JHS) girls highlighted academic satisfaction; while school-life balance, and virtual learning helped as challenges and opportunities. The females found school-life balance, communication (F(1,149)=11.098; F(1,149)=8.430, p<0.01), academic fulfilment, self-directedness, and time-management (F(1,149)=4.224; F(1,149)=4.470; F(1,149)=4.030, p<0.05) more difficult than did the males. Senior high school (SHS) students were less satisfied with the virtual teaching (F(1,149)=14.391, p<0.001), technology use (F(1,149)=7.342, p<0.01), and communication (F(1,149)=3.934, p<0.05) than JHS students. Males were more satisfied with school and teachers’ assistance (F(1,149)=7.482, p<0.01). Some viewed virtual learning more favourably; and they regard themselves as being adaptive; they think the subject matter and learning tasks are interrelated; and they viewed virtual feedback more positively (F(1,149)=6.438; F(1,149)=5.900; F(1,149)=5.183; F(1,149)=4.470, p<0.05). The JHS students reported subject matter and the virtual learning tasks as being interrelated; and they valued virtual feedback, school and teacher support, and the adaptability to change. Challenges and opportunities may serve as the foundation for establishing a more inclusive policy on virtual learning implementation, with school and stakeholders’ cooperation needed to sustain learners’ holistic development.

We live with the legacy of injustice, political as well as personal. Even if our governments are now democratically elected and governed, our societies are scarred by forms of power and privilege accrued from a time in which people’s race, sex, class and religion were grounds for denying them a role in government, or in the selection of those who governed them. What does that past imply for the treatment of religion in democratic states? The problem is particularly pressing (...) once one accepts that religious freedom is not just a matter of individuals’ freedom of conscience and worship, but of people’s claims to associate with others through institutions whose powers, status and commitment to equality are very different (Laborde, 2015). If this means that churches pose some of the same philosophical and practical problems as families, from a democratic perspective, the fact that churches have no obvious point or justification, beyond being the repository of the claims to conscience of their members, appears to distinguish them from the former. In principle, this should make it easier to think about the claims of government, as compared to those of churches. In practice, however, it may simply bring into sharper focus philosophical and political challenges to equality that contemporary democracies now face. (shrink)

Evolutionary psychology claims biological inclinations for certain behaviors (e.g., a desire for more frequent sex and more sexual partners by males as compared to females), and the origin of these inclinations in natural selection. Jerry Fodor’s recent book, The Mind Doesn’t Work that Way (2000), grants the nativist case for such biological grounding but disputes the presumed certainty of its origin in natural selection. Nevertheless, there is today a consensus that at least some of the claims of evolutionary (...) psychology are true, and their broad appeal suggests that many see them as easy insights into and possible license for some controversial behaviors. Evolutionary psychologists, on the other hand, caution that an origin in natural selection implies only an inclination for certain behaviors, and not that the behaviors will be true of all people, will lead to happiness or are morally correct. But such cautions can be as facile as the simplistic positions they are intended to counter. A biological basis implies tendencies to behaviors that will be pleasurable when engaged in, and that can be modified to an extent and at a psychic cost that is, at best, not fully understood. Also, while it is true that naturally selected behaviors are not necessarily moral, the implications of current evolutionary psychology cast doubt on any absolute foundation for morality at all, as well as suggesting limits on our ability to fully understand both ourselves and the universe around us. However, this does not mean that our (relative) values or apparent free will are any less real or important for us. (shrink)

The importance of this practice is highlighted by its contribution to maximizing desired characteristics in herds, such as meat quality, reproductive efficiency and resistance to environmental conditions adverse. This work describes and analyzes the advanced techniques used in this process, including genomic selection, embryo sexing, in vitro production, non-surgical protocols, reproductive synchronization, embryo cryopreservation and the use of fertility markers. An in-depth understanding of these techniques is critical to the success of embryo transfer, as well as the ability to customize and enhance specific herd characteristics. Emphasizing the importance of the expertise of professionals specialized in bovine reproduction, this work seeks to offer a comprehensive view of current practices and technological advances in this field. When combining science and practice, it becomes important to compare techniques, as well as relate efficient results to promote genetic quality, bring sustainability and involve the technique in an updated industry scenario.

The study examined the differential item functioning (DIF) of 2018 Basic Education Certificate examination (BECE) in Mathematics tests of National Examination Council (NECO) and BECE of Akwa Ibom State government in Nigeria. The invariance in the tests with regards to sex was considered using Item Response Theory (IRT) approach. The study area was Akwa Ibom state of Nigeria having a student population of 58,281 for the examination. The sample was made of up 3810 students drawn through a multi-stage sampling approach. (...) The multidimensional IRT (MIRT) package implemented in R-programming language software was applied in analyzing the data. The findings reveal that BECE of NECO displayed 23(38.3%) DIF items while BECE of Akwa Ibom State had 37 (61.7%) DIF items in terms of sex. The findings also revealed that, in the two examinations, more items favoured the male candidates more than the female candidates in terms of performance. It was recommended that IRT model should be adopted by test developers to determine item parameters for selection of good items to ensure quality of items before administration. Test equating of students who write equivalent form examinations conducted by different examining bodies was also recommended for admission and placement of candidates to determine actual group differences in performance. The study posits that research on Differential Item Functioning is inconclusive, so should be encouraged. (shrink)

In the December 2015 Issue of the Police Journal Sam Poyser and Rebecca Milne addressed the subject of miscarriages of justice. Cold case investigations can address some of these wrongs. The salient points for attention are those just before his sudden death: Milligan was appointed Private Secretary to Jonathan Aitken, the then Minister of Arms in the Conservative government in 1994. The known facts are as follows: 1. Stephen David Wyatt Milligan was found deceased on Tuesday 8th February 1994 at (...) his Chiswick, West London house where he lived alone. His body was found by his secretary Vera Taggart who was told by Julie Kirkbride where a spare key to his London house was kept and who decided to go to his house that day because he was not answering his telephone. Police said he had made one last telephone call on Saturday evening at 9.00pm. 2. Stephen David Wyatt Milligan had been the elected Member of Parliament (‘MP’) for Eastleigh in Hampshire since 1992. 3. The important topics this MP was addressing in 1994 at the time of his death included: (i) rail privatization plans and the impact through job losses on communities, especially his own constituency of Eastleigh; (ii) arms dealings with Saudi Arabia, especially with his previous intelligence gathered as an economics journalist for esteemed publications; (iii) the UK military industry; (iv) homosexuality among senior government Ministers, as revealed by British footballer Fasanu; (v) personal relationship and planned marriage to his fiancée (Julie Kirkbride) who at the time was a political journalist. 4. Stephen Milligan was also appointed as Parliamentary Private Secretary to Jonathan Aitken, Arms Minister and this position must have required that he came ‘up to speed’ on international arms trade and indeed its relation to bribery and corruption across jurisdictions. Milligan’s experience and knowledge as a former high-level political and economics journalist must have been of huge benefit to government minister Jonathan Aitken who was later imprisoned for perjury. 5. Regarding Stephen Milligan’s death in 1994, the Guardian newspaper in their immediate obituary said that ‘The death of one of the government's most outspoken and loyal supporters will pose a stiff electoral test for the Tories to surmount. He was on the left of the Tory party - he had even had a brief flirtation with the SDP when it was formed - and was a noted Euro-enthusiast… the death of one of the government's most outspoken and loyal supporters will pose a stiff electoral test for the Tories to surmount. Regarding Stephen Milligan’s sudden and unexpected death in 1994, MP David Willetts (Conservative, Havant) said in March 2015, in his address in the House of Commons. ‘…The inevitable ups and downs and triumphs and disasters of politics are among the great features of this place. There are colleagues in all parts of the House who are tolerant and understanding. There are friendships that keep the downs as well as the ups of politics in perspective. Having entered the House in 1992, I think particularly of two good friends, Judith Chaplin and Stephen Milligan, who both died within two years of being elected; that loss stayed with me for a long time...’ 6. On 28 February 2000, in the House of Commons, at Column 106, Mr Mike Hancock (Portsmouth) said, on the deaths of Michael Colvin and of Stephen Milligan MP: ‘I knew Michael Colvin for nearly 30 years, from when he was first elected to Hampshire county council. During my time as leader of that council, he and the late former Member of Parliament for Eastleigh, Stephen Milligan, were usually the only Members of Parliament who readily supported the council when necessary. Michael Colvin supported many ventures in the county of Hampshire. He will be missed here, in his constituency, and in Europe, and I stress that Hampshire has lost a staunch supporter. I am sure that the county will at some stage want to record its regret at his death and its deepest appreciation of the part that he played in its life....’ -/- Mike Hancock had, like Stephen Milligan, served on the Select Committee on Defence. It is interesting that he mentioned Stephen Milligan’s support as MP for Eastleigh when Milligan had only been so appointed a couple of years before his sudden death, as compared to 30 years of support from Mike Colvin. 7. Mr Andrew Robathan (for Blaby) said in the House of Commons Hansard Debates on 27 January1997, (Column 62) (on the registering of sex offenders): ‘I remember the death of my honourable friend Stephen Milligan, who represented Eastleigh. The press reports of the time stated that each Metropolitan police station had a police officer in the pay of newspapers. I do not know whether that is true, but I am aware that the police are not renowned for being entirely secure with their information…’ This statement is mischievous and it has been demonstrated time and time again, as being untrue, especially during the recent press inquiry leading to the four-volume Leveson Report, published in November 2012, into phone hacking and the ethics and culture of the UK media, pursuant to section 26 of the Inquiries Act 2005, and ordered by the House of Commons to be printed on 29 November 2012, ISBN: 9780102981063, by the Stationery Office Limited on behalf of the Controller of Her Majesty’s Stationery Office. In Volume 4 of the 2012 Leveson Report, chapter 4 concluded on the Press Complaints Commission (‘PCC’) and its effectiveness and revealed that the PCC does not initiate its own investigations other than those ‘needed to head off criticism of the press or self-regulation- or to accept complaints from third parties across the board and on a transparent basis… and the report states that ‘the resources of the police are limited’ in terms of being able to fully inspect the Press and media reports.

Darwinism presents a paradox. It discredits the notion that one’s life has any intrinsic meaning, yet it predicts that we are designed by Darwinian natural selection to generally insist that it must—and so necessarily designed to misunderstand and doubt Darwinism. The implications of this paradox are explored here, including the question of where then does the Darwinist find meaning in life? The main source, it is proposed, is from cognitive domains for meaning inherited from sentient ancestors—domains that reveal our (...) evolved human nature as the fool that it is: given to distractions and delusions of many kinds, designed by natural selection primarily for one essential purpose—to allay our instinctual fear of failed legacy, rooted in our uniquely human awareness that we are not immortal. Darwinism, however, also teaches that genuine legacy is a fate enjoyed only by individual genes. Accordingly, as argued here, those genes with the grandest legacy—and hence rampant within us—are of two types: “legacy-drive” genes delude us into thinking that the legacy can be individually and personally ours; and “leisure-drive” genes distract us from the agonizing truth that it can never be. The most rudimental delusion of legacy is the perception of offspring as vehicles for memetic legacy—the transmission of resident memes from one’s mind to the minds and behaviors of offspring—thus also ensuring genetic legacy: the transmission of resident genes, including importantly, genes inherited from ancestors that influence both legacy and leisure drives. Today, legacy- and leisure-drive genes reveal their phenotypes across a wide range of human affairs, and together with the phenotypes of survival- and sex-drive genes, they provide a foundation for a novel view of the Darwinian roots of cultural evolution.

This study aimed to improve the curriculum electives of the Science-Enhanced Program using a tracer of ScienceOriented Section alumni from 2004 to 2015. It assessed the Science-Enhanced Program's strengths and weaknesses as viewed by alumni, collected their recommendations to improve the Science-Enhanced Curriculum in connection with current field demands, and constructed a SEP learner's packet. This study used a mixed-methods strategy. A total of 238 respondents were purposefully selected via quota sampling. The alumni's demographic profile based on their sex, civil (...) status, educational attainment, employment information, as well as two extra questions, were collected using a tracer form. The first question focused on alumni perceptions of the science-enhanced program's strengths and weaknesses, and the second question focused on their suggestions for improving the science-enhanced curriculum with respect to current field demands. After gathering the data and assessing the results, it has been concluded that the strengths of the science-enhanced program are the following: elective subjects offered, teaching quality, interdisciplinary learning, and student workload. Meanwhile, the learning environment, the research capacity, and the facilities provided were listed as the weaknesses of the said program. The respondents concurred that the curriculum should include courses in robotics, programming, and other IT-related topics. The alumni also agreed that students should be exposed to more real-world scenarios in the curriculum. Hence, it has been validated that it can be used as a guide in crafting the competencies in formulating the SEP Learners' Packet. (shrink)

Objective: Reference values have gained universal acceptance as the most powerful material that helps the decision-making-implementation process of the clinical laboratory. These values ​​may be affected by the geographical location, dietary habits, and other lifestyle changes of individuals applying to the clinical laboratory. Our study aims to determine the reference ranges for the biochemistry test panel, thyroid function tests, and insulin hormone levels, which are frequently needed by clinicians for the province of Gaziantep, with samples obtained from healthy individuals. -/- (...) Materials and Methods: In the study phase, the selection of reference individuals was carried out using the direct method a priori. For the study group, healthy individuals (224 men, 243 women) aged 18-45 were selected. Reference intervals (95% limit) were calculated according to the non-parametric method. -/- Results: When the reference intervals obtained in our study were compared with the reference intervals of the manufacturer, there were differences (> 10% lower or higher) in the upper and lower limits in urea (female and male), creatinine (male), HDL (female), AST (female and male), ALT (female), GGT (female), ALP (common), Lipase (common), CK (male), iron (male), TSH (female and male) markers. Male and female reference intervals for HDL, AST, ALT, and TSH differed significantly. Manufacturer reference ranges for these parameters were common to both sexes. -/- Conclusion: As a result, differences were determined between most of the reference intervals obtained in our study and the reference intervals we routinely use. We think the difference in the reference intervals is due to the differences in dietary habits and environmental factors. (shrink)

The family is a social group. Its characteristics are among other things; common residence, co-operation and reproduction. The family has always been considered to be the foundation or nucleus of the society; the most basic unit of its organization. The structure of the family varies according to each society. In pre-colonial era, the family as a social group among the Yorùbá, was a large unit, and extended in nature. They were bound together by the realization of having a common ancestor; (...) alájọbí. All the members of the family see one another as blood relations, as such incest was (and still is) a taboo. Apart from this, sexual relationship among the Yorùbá is heterosexual and permissible only in marriage; between husband and his wife/wives. Though extra-marital relationships are practiced, it is frowned at for men, but intolerable for women. Homosexuality is also a taboo; punishable by public disgrace, with culprits liable to excommunication from the society, especially if unrepentant. It cannot be totally ruled out that these anomalous relationships were not secretly engaged in by few non-conformists among the Yorùbá, before coming into contact with the West, the fact remains that the magnitude by which they are practiced in present times is alarming; threatening the harmony and cultural heritage of the Yorùbá. This fear is expressed in the literary genres of the Yorùbá, especially the film, which is the contemporary popular theatre of the Yorùbá of Nigeria and other tribes in Africa. This study examined sexual relationship among members of the family, in randomly selected Yorùbá films that have family-living as their major or minor themes; to know how affected is the stability of family (sexual) relationship among the Yorùbá. This is in the light of evolving modernity; with its individualistic life-style of people globally, as against the inherited communal social organization of the Yorùbá; built around the virtuous ọmọlúwàbí principle. The plausible reasons for the anomalous behaviors are also examined. Our findings are that prevailing strict traditional conditions, living in private homes as nuclear family, not being properly oriented in Yorùbá cultural values, increased exposition to Western lifestyles and its more relaxed societal expectations, and non-realization of the possibility of anomalous sexual behaviors as mental and biological issues that can be medically treated; are some of the reasons why such behaviors manifest, and are becoming prevalent. We have suggested communal encouragement with empathy, to seek medical assistance for and by the ‘diseased’ person. One finding here is that prevailing traditional conditions, ignorance, poor orientation and westernization present the anomaly mildly and make people not to see anomalous sex behavious as a mental disorder which requires medical attention.

The study investigated school characteristics and enrolment trend in upper basic schools in Akwa Ibom State Nigeria from 2008-2016. Two research questions were answered while two null hypotheses were also tested. The study adopted a descriptive survey research design. Census technique was adopted in selecting all the 227 public upper basic schools in the area of study. An instrument tagged “School Characteristics and Enrolment in Upper Basic Schools Checklist (SCEUBSC)” was used for data collection. Descriptive statistics (percentages) was used to (...) summarize data relating to the research questions, bar chart was used for illustrations of the enrolment pattern while independent t-test was used to test the two null hypotheses at .05 alpha level. Findings revealed that enrolment in upper basic schools in Akwa Ibom State was high in single-sex schools and boarding schools, while it was low in mixed-sex schools and day schools. Based on the findings, it was concluded that there was an upward trend in enrolment in all the schools from 2008- 2013 and a downward trend from 2015-2016. It was recommended among others that research allocation in terms of personnel and infrastructures should be evenly distributed across the state as these will reduce rural-urban migration. Keywords:.

This collection of articles was written over the last 10 years and edited them to bring them up to date (2017). All the articles are about human behavior (as are all articles by anyone about anything), and so about the limitations of having a recent monkey ancestry (8 million years or much less depending on viewpoint) and manifest words and deeds within the framework of our innate psychology as presented in the table of intentionality. As famous evolutionist Richard Leakey says, (...) it is critical to keep in mind not that we evolved from apes, but that in every important way, we are apes. If everyone was given a real understanding of this (i.e., of human ecology and psychology to actually give them some control over themselves), maybe civilization would have a chance. As things are however the leaders of society have no more grasp of things than their constituents and so collapse into anarchy is inevitable. -/- It is critical to understand why we behave as we do and so the first section presents articles that try to describe (not explain as Wittgenstein insisted) behavior. Section one starts with a brief review of the logical structure of rationality which provides some heuristics for the description of language (mind) and gives some suggestions as to how this relates to the evolution of social behavior. This centers around the two writers I have found the most important in this regard, Ludwig Wittgenstein and John Searle, whose ideas I combine and extend within the dual system (two systems of thought) framework that has proven so useful in recent thinking and reasoning research. As I note, there is in my view essentially complete overlap between philosophy, in the strict sense of the enduring questions that concern the academic discipline, and the descriptive psychology of higher order thought (behavior). Once one has grasped Wittgenstein’s insight that there is only the issue of how the language game is to be played, one determines the Conditions of Satisfaction (what makes a statement true or satisfied etc.) and that is the end of the discussion. -/- Since philosophical problems are the result of our innate psychology, or as Wittgenstein put it, due to the lack of perspicuity of language, they run throughout human discourse, so there is endless need for philosophical analysis, not only in the ‘human sciences’ of philosophy, sociology, anthropology, political science, psychology, history, literature, religion, etc., but in the ‘hard sciences’ of physics, mathematics, and biology. It is universal to mix the language game questions with the real scientific ones as to what the empirical facts are. Scientism is ever present and the master has laid it before us long ago, i.e., Wittgenstein (hereafter W) beginning with the Blue and Brown Books in the early 1930’s. -/- "Philosophers constantly see the method of science before their eyes and are irresistibly tempted to ask and answer questions in the way science does. This tendency is the real source of metaphysics and leads the philosopher into complete darkness." (BBB p18) -/- The key to everything about us is biology, and it is obliviousness to it that leads millions of smart educated people like Obama, Chomsky, Clinton and the Pope to espouse suicidal utopian ideals that inexorably lead straight to Hell On Earth. As W noted, it is what is always before our eyes that is the hardest to see. We live in the world of conscious deliberative linguistic System 2, but it is unconscious, automatic reflexive System 1 that rules. This is the source of the universal blindness described by Searle’s The Phenomenological Illusion (TPI), Pinker’s Blank Slate and Tooby and Cosmides’ Standard Social Science Model. -/- The astute may wonder why we cannot see System 1 at work, but it is clearly counterproductive for an animal to be thinking about or second guessing every action, and in any case there is no time for the slow, massively integrated System 2 to be involved in the constant stream of split second ‘decisions’ we must make. As W noted, our ‘thoughts’ (T1 or the ‘thoughts’ of System 1) must lead directly to actions. -/- It is my contention that the table of intentionality (rationality, mind, thought, language, personality etc.) that features prominently here describes more or less accurately, or at least serves as an heuristic for, how we think and behave, and so it encompasses not merely philosophy and psychology, but everything else (history, literature, mathematics, politics etc.). Note especially that intentionality and rationality as I (along with Searle, Wittgenstein and others) view it, includes both conscious deliberative System 2 and unconscious automated System 1 actions or reflexes. -/- Thus all the articles, like all behavior, are intimately connected if one knows how to look at them. As I note, The Phenomenological Illusion (oblivion to our automated System 1) is universal and extends not merely throughout philosophy but throughout life. I am sure that Chomsky, Obama, Zuckerberg and the Pope would be incredulous if told that they suffer from the same problem as Hegel, Husserl and Heidegger, (or that that they differ only in degree from drug and sex addicts in being motivated by stimulation of their frontal cortices by the delivery of dopamine via the ventral tegmentum and the nucleus accumbens) but it’s clearly true. While the phenomenologists only wasted a lot of people’s time, they are wasting the earth and their descendant’s future. Section one continues with other views of behavior which my reviews attempt to correct and put in context with minimal theory. -/- The next section describes the digital delusions which confuse the language games of System 2 with the automatisms of System one, and so cannot distinguish biological machines (i.e., people) from other kinds of machines (i.e., computers). The ‘reductionist’ claim is that one can ‘explain’ behavior at a ‘lower’ level, but what actually happens is that one does not explain human behavior but a ‘stand in’ for it. Hence the title of Searle’s classic review of Dennett’s book (“Consciousness Explained”)— “Consciousness Explained Away”. In most contexts ‘reduction’ of higher level emergent behavior to brain functions, biochemistry, or physics is incoherent. Even for chemistry or physics the path is blocked by chaos and uncertainty. Anything can be ‘represented’ by equations, but when they ‘represent’ higher order behavior, it is not clear what the ‘results’ mean. Reductionist metaphysics is a joke but most scientists and philosophers lack the appropriate sense of humor. -/- Another hi-tech delusion is that the we will be saved from the pure evil (selfishness) of System 1 by computers/AI/robotics/ nanotech/genetic engineering created by System 2. The No Free Lunch principal tells us there will be serious and possibly fatal consequences. The adventurous may regard this principle as a higher order emergent expression of the Second Law of Thermodynamics. -/- The last section describes The One Big Happy Family Delusion , i.e., that we are selected for cooperation with everyone and that the euphonious ideals of Democracy, Diversity and Equality will lead us into utopia. Again the No Free Lunch Principle ought to warn us it cannot be true, and we see throughout history and all over the contemporary world, that without strict controls, selfishness and stupidity gain the upper hand and soon destroy any nation that embraces it. In addition, the monkey mind steeply discounts the future, and so we sell our descendant’s heritage for temporary comforts greatly exacerbating the problems. -/- I describe versions of this delusion (i.e., that we are basically ‘friendly’ if just given a chance) as it appears in some recent books on sociology/biology/economics. I end with an essay on the great tragedy playing out in America and the world, which can be seen as a direct result of our evolved psychology manifested as the inexorable machinations of System 1. Our evolved psychology, eminently adaptive and eugenic on the plains of Africa ca. 50,000 years ago, when many of our ancestors left Africa, to ca. 6 million years ago, when we split from chimpanzees (i.e., in the EEA or Environment of Evolutionary Adaptation), but now maladaptive and dysgenic and the source of our Suicidal Utopian Delusions. So, like all discussions of behavior, this book is about evolutionary strategies, selfish genes and inclusive fitness. (shrink)

This collection of articles was written over the last 10 years and edited to bring them up to date (2017). The copyright page has the date of the edition and new editions will be noted there as I edit old articles or add new ones.

As things are however the leaders of society have no more grasp of things than their constituents and so collapse into anarchy is inevitable. The first group of articles attempts to give some insight into how we behave that is reasonably free of the theoretical delusions that are universal. In the next group, I show how these insights apply by reviewing some books in philosophy and psychology. Next I review books on science and religion and finally provide reviews and articles showing how understanding of both science and philosophy gives insight into the tragic delusions destroying the world. People believe that society can be saved by science, religion and politics, so I provide some suggestions as to why this is unlikely via short articles and reviews of recent books by well-known writers. It is critical to understand why we behave as we do and so the first section presents articles that try to describe (not explain as Wittgenstein insisted) behavior. I start with a brief review of the logical structure of rationality, which provides some heuristics for the description of language (mind, rationality, personality) and gives some suggestions as to how this relates to the evolution of social behavior. This centers around the two writers I have found the most important in this regard, Ludwig Wittgenstein and John Searle, whose ideas I combine and extend within the dual system (two ii systems of thought) framework that has proven so useful in recent thinking and reasoning research. As I note, there is in my view essentially complete overlap between philosophy, in the strict sense of the enduring questions that concern the academic discipline, and the descriptive psychology of higher order thought (behavior). Once one has grasped Wittgenstein’s insight that there is only the issue of how the language game is to be played, one determines the Conditions of Satisfaction (what makes a statement true or satisfied etc.) and that is the end of the discussion. Since philosophical problems are the result of our innate psychology, or as Wittgenstein put it, due to the lack of perspicuity of language, they run throughout human discourse and behavior, so there is endless need for philosophical analysis, not only in the ‘human sciences’ of philosophy, sociology, anthropology, political science, psychology, history, literature, religion, etc., but in the ‘hard sciences’ of physics, mathematics, and biology. It is universal to mix the language game questions with the real scientific ones as to what the empirical facts are. Scientism is ever present and the master has laid it before us long ago, i.e., Wittgenstein (hereafter W) beginning with the Blue and Brown Books in the early 1930’s. "Philosophers constantly see the method of science before their eyes and are irresistibly tempted to ask and answer questions in the way science does. This tendency is the real source of metaphysics and leads the philosopher into complete darkness." (BBB p18) The key to everything about us is biology, and it is obliviousness to it that leads millions of smart educated people like Obama, Chomsky, Clinton and the Pope to espouse suicidal utopian ideals that inexorably lead straight to Hell on Earth. As W noted, it is what is always before our eyes that is the hardest to see. We live in the world of conscious deliberative linguistic System 2, but it is unconscious, automatic reflexive System 1 that rules. This is the source of the universal blindness described by Searle’s The Phenomenological Illusion (TPI), Pinker’s Blank Slate and Tooby and Cosmides’ Standard Social Science Model. The astute may wonder why we cannot see System 1 at work, but it is clearly counterproductive for an animal to be thinking about or second guessing every action, and in any case, there is no time for the slow, massively integrated System 2 to be involved in the constant stream of split second ‘decisions’ we must make. As W noted, our ‘thoughts’ (T1 or the ‘thoughts’ of System 1) must lead directly to actions. iii It is my contention that the table of intentionality (rationality, mind, thought, language, personality etc.) that features prominently here describes more or less accurately, or at least serves as an heuristic for, how we think and behave, and so it encompasses not merely philosophy and psychology, but everything else (history, literature, mathematics, politics etc.). Note especially that intentionality and rationality as I (along with Searle, Wittgenstein and others) view it, includes both conscious deliberative System 2 and unconscious automated System 1 actions or reflexes. Thus, all the articles, like all behavior, are intimately connected if one knows how to look at them. As I note, The Phenomenological Illusion (oblivion to our automated System 1) is universal and extends not merely throughout philosophy but throughout life. I am sure that Chomsky, Obama, Zuckerberg and the Pope would be incredulous if told that they suffer from the same problem as Hegel, Husserl and Heidegger, (or that that they differ only in degree from drug and sex addicts in being motivated by stimulation of their frontal cortices by the delivery of dopamine (and over 100 other chemicals) via the ventral tegmentum and the nucleus accumbens), but it’s clearly true. While the phenomenologists only wasted a lot of people’s time, they are wasting the earth and their descendant’s futures. Many of the articles describe the ‘digital delusions’, which confuse the language games of System 2 with the automatisms of System 1, and so cannot distinguish biological machines (i.e., people) from other kinds of machines (i.e., computers). The ‘reductionist’ claim is that one can ‘explain’ behavior at a ‘lower’ level, but what actually happens is that one does not explain human behavior but a ‘stand in’ for it. Hence the title of Searle’s classic review of Dennett’s book (“Consciousness Explained”)— “Consciousness Explained Away”. In most contexts ‘reduction’ of higher level emergent behavior to brain functions, biochemistry, or physics is incoherent. Also for ‘reduction’ of chemistry or physics, the path is blocked by chaos and uncertainty. Anything can be ‘represented’ by equations, but when they ‘represent’ higher order behavior, it is not clear (and cannot be made clear) what the ‘results’ mean. Reductionist metaphysics is a joke, but most scientists and philosophers lack the appropriate sense of humor. Other digital delusions are that we will be saved from the pure evil (selfishness) of System 1 by computers/AI/robotics/ nanotech/genetic engineering created by System 2. The No Free Lunch principal tells us there will be serious and possibly fatal consequences. The adventurous may regard this principle as a higher order emergent expression of the Second Law of Thermodynamics. Hi-tech enthusiasts hugely underestimate the problems iv resulting from unrestrained motherhood, and of course it is neither profitable nor politically correct (and now with third world supremacism dominant, not even possible) to be honest about it. The last section describes various versions of the ‘altruism delusion’ that we are selected for cooperation, and that the euphonious ideals of Democracy, Diversity and Equality will lead us into utopia, if we just manage things correctly (the possibility of politics). Again, the No Free Lunch Principle ought to warn us it cannot be true, and we see throughout history and all over the contemporary world, that without strict controls, selfishness and stupidity gain the upper hand and soon destroy any nation that embraces it. In addition, the monkey mind steeply discounts the future, and so we cooperate in selling our descendant’s heritage for temporary comforts, greatly exacerbating the problems. I describe versions of this delusion (i.e., that we are basically ‘friendly’ if just given a chance) as it appears in some recent books on sociology/biology/economics. I end with an essay on the great tragedy playing out in America and the world, which can be seen as a direct result of our evolved psychology manifested as the inexorable machinations of System 1. Our psychology, eminently adaptive and eugenic on the plains of Africa from ca. 6 million years ago, when we split from chimpanzees, to ca. 50,000 years ago, when many of our ancestors left Africa (i.e., in the EEA or Environment of Evolutionary Adaptation), is now maladaptive and dysgenic and the source of our Suicidal Utopian Delusions. So, like all discussions of behavior (philosophy, psychology, sociology, biology, anthropology, politics, law, literature, history, economics, soccer strategies, business meetings, etc.), this book is about evolutionary strategies, selfish genes and inclusive fitness (kin selection). Many accept the delusion that we are selected for cooperation with people generally (group selection or altruism) and not just our immediate relatives (kin selection or inclusive fitness), so I spend some time in the essays of the last section demolishing this fantasy. One thing rarely mentioned by the group selectionists is the fact that, even were ‘group selection’ possible, selfishness is at least as likely (probably far more likely in most contexts) to be group selected for as altruism. Just try to find examples of true altruism in nature –the fact that we can’t (which we know is not possible if we understand evolution) tells us that its apparent presence in humans is an artefact of modern life concealing the facts, and that it can no more be selected for than the tendency to suicide (which in fact it is). One does not really need science or mathematics to grasp this – it is crushingly obvious that an v organism cannot be selected for behavior that decreases the frequency of its own genes in the next generation. One might also benefit from considering a phenomenon never (in my experience) mentioned by group selectionists -- cancer. No group has as much in common as the (originally) genetically identical cells in our own bodies-a 100 trillion cell clone-- but we are all born with thousands and perhaps millions of cells that have already taken the first step on the path to cancer and generate millions to billions of cancer cells in our life. If we did not die of other things first, we (and perhaps all multicellular organisms) would all die of cancer. Only a massive and hugely complex mechanism built into our genome that represses or derepresses trillions of genes in trillions of cells, and kills and creates billions of cells a second, keeps the majority of us alive long enough to reproduce. One might take this to imply that a just, democratic and enduring society for any kind of entity on any planet in any universe is only a dream, and that no being or power could make it otherwise. It is not only ‘the laws’ of physics that are universal and inescapable, or perhaps we should say that inclusive fitness is a law of physics. The great mystic Osho said that the separation of God and Heaven from Earth and Humankind was the most evil idea that ever entered the Human mind. In the 20th century an even more evil notion arose—that humans are born with rights, rather than having to earn privileges. Thus, every day the population increases by 200,000, who must be provided with resources to grow and space to live, and who soon produce another 200,000 etc. And one almost never hears it noted that what they receive must be taken from those already alive. Their lives diminish those already here in both major obvious and countless subtle ways. Every new baby destroys the earth from the moment of conception. There cannot be human rights without human wrongs. It cannot be more obvious, but one will never see the streets full of protesters against motherhood. America and the world are in the process of collapse from excessive population growth, most of it for the last century and now all of it due to 3rd world people. Consumption of resources and the addition of 4 billion more ca. 2100 will collapse industrial civilization and bring about starvation, disease, violence and war on a staggering scale. The earth loses about 2% of it’s topsoil every year, so as it nears 2100, most of it’s food growing capacity will be gone. Billions will die and nuclear war is all but certain. In America, this is being hugely accelerated by massive immigration and immigrant reproduction, combined with abuses made possible by democracy. Depraved human nature inexorably turns the dream of democracy and diversity into a vi nightmare of crime and poverty. China will continue to overwhelm America and the world, as long as it maintains the dictatorship which limits selfishness. The root cause of collapse is the inability of our innate psychology to adapt to the modern world, which leads people to treat unrelated persons as though they had common interests. This, plus ignorance of basic biology and psychology, leads to the social engineering delusions of the partially educated who control democratic societies. Few understand that if you help one person you harm someone else—there is no free lunch and every single item anyone consumes destroys the earth beyond repair. Consequently, social policies everywhere are unsustainable and one by one all societies without stringent controls on selfishness will collapse into anarchy or dictatorship. Without dramatic and immediate changes, there is no hope for preventing the collapse of America, or any country that follows a democratic system. The popular notions supported by the Democratic Party and Third World Supremacists are that Democracy, Diversity, Equality and Social Justice will produce a Utopia in America and the world, but it is clear as crystal that they unavoidably foster selfishness and divisiveness and are producing collapse. Hence my concluding essay “Suicide by Democracy”. The most basic facts, almost never mentioned, are that there are not enough resources in America or the world to lift a significant percentage of the poor out of poverty and keep them there. Even the attempt to do this is already bankrupting America and destroying the world. The earth’s capacity to produce food decreases daily, as does our genetic quality. And now, as always, by far the greatest enemy of the poor is other poor and not the rich. -/- My writings are available as paperbacks and Kindles on Amazon. -/- Talking Monkeys: Philosophy, Psychology, Science, Religion and Politics on a Doomed Planet - Articles and Reviews 2006-2017 (2017) ASIN B071HVC7YP. -/- The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle--Articles and Reviews 2006-2016 (2017) ASIN B071P1RP1B. -/- Suicidal Utopian Delusions in the 21st century: Philosophy, Human Nature and the Collapse of Civilization - Articles and Reviews 2006-2017 (2017) 2nd printing with corrections (Feb 2018) ASIN B0711R5LGX -/- Suicide by Democracy: an Obituary for America and the World (2018) ASIN B07CQVWV9C -/- .

RESUMO A Transferência de Embrião (TE) em bovinos se trata de uma técnica mundialmente disseminada com objetivo de aumentar a capacidade reprodutiva da fêmea. Mantém vínculo direto com outras técnicas das biotecnologias da reprodução, como, a Ovum Pick-Up (OPU), Produção In Vitro e In Vivo de embriões (PIVE) e Transferência de Embrião em Tempo Fixo (TETF), sendo estas, técnicas que fazem parte de um processo, que vai desde a seleção de doadoras, passando pelo preparo dos embriões até sua inovulação em (...) receptoras criteriosamente selecionadas. Com seu avanço, várias tecnologias de manejo vêm sendo implantadas: formas no transporte de embriões, protocolos de sincronização de doadoras e receptoras, e protocolos de recuperação de oócitos para produção de embriões. Isto infundiu a tecnologia, porém, os investimentos previstos para a produção de um animal de alto mérito genético limita sua utilização. Contudo, esta análise abordou avanços tecnológicos essenciais para o sucesso da TE, incluindo novos protocolos, sexagem de embriões, além do uso de embriões congelados Direct Transfer (DT) e vitrificados. No entanto, é claro que o sucesso do procedimento está no processo como um todo, em destaque ressalta-se que é de grande valia que o profissional apto a executar a técnica esteja sempre preparado e atualizado garantindo qualidade, eficiência e sustentabilidade na pecuária. Esta revisão foi desenvolvida com o propósito de adquirir conhecimento teórico, de forma detalhada e crítica, nas técnicas e procedimentos de Transferência de Embriões em bovinos, incluindo a colheita, manipulação e implantação de embriões. Palavras-chaves: Bovino, doadora, embrião, receptora. ABSTRACT Embryo Transfer (ET) in cattle is a globally widespread technique aimed at enhancing the reproductive capacity of females. It is closely linked to other techniques in reproductive biotechnologies, such as Ovum Pick-Up (OPU), In Vitro and In Vivo Embryo Production (PIVE), and Timed Embryo Transfer (TET), all of which are part of a process that ranges from donor selection, through embryo preparation, to their inoculation into carefully chosen recipients. With its advancement, various management technologies have been implemented: including methods for embryo transport, synchronization protocols for donors and recipients, and oocyte recovery protocols for embryo production. Although technology has been infused, the anticipated investments for producing animals of high genetic merit limit its widespread use. However, this analysis addressed essential technological advances for the success of ET, including new protocols, embryo sexing, as well as the use of frozen-thawed (DT) and vitrified embryos. Nevertheless, it is clear that the success of the procedure lies in the entire process. Notably, it emphasizes the significant value of having a qualified professional who is always prepared and updated to ensure quality, efficiency, and sustainability in livestock farming. This literary review was developed with the purpose of acquiring theoretical knowledge, in a detailed and critical way, on the techniques and procedures of Embryo Transfer in cattle, including the collection, manipulation and implantation of embryos.

Demography is typically defined as the study of human populations and the changes in their quantity associated with migration, fertility, and mortality. The term demography comes from Greek word and means “describing people.” Thus, this discipline deals with the characteristics of the population, taking into account features such as, sex ratio, age structure, composition, spatial distribution, and population density. In addition, sometimes a distinction is made between “formal demography” or “demographic analysis,” which includes the statistical analysis of population parameters and (...) their dynamics, and “population studies,” that is, the analysis of the causes and effects of changes in the structure of the population in a broader context and in connection with other phenomena and processes.
