Domestic violence is identified across the globe as a menace as it poses a threat to the mental health of its victims, the significant others of the victim and the security of a nation at large. In some cases, the victim of domestic violence is a pregnant woman and harm is caused not only to a woman but her fetus also and this calls for urgent psychological assessment and intervention. Although there is no doubt that psychological tests are effective in (...) the assessment of domestic violence, using the psychometric properties obtained from a different population may produce generate inaccurate findings. This paper therefore attempts the validation study of Women Abuse Screening Tool (WAST) using a sample of 379 pregnant women attending antenatal clinic at the State Specialist Hospital, Osogbo, Osun State, Nigeria. The study derived a Cronbach’s Alpha Reliability of 0.758, p <.05 and a Guttman split-half coefficient of 0.683, p <.05. Furthermore, concurrent validity of Women Abuse Screening Tool (WAST) and Ongoing Abuse Screen (OAS) was established as 0.29, p<.05. The norms of the instrument were given as 2.38 for tolerable level of domestic violence and 5.79 for severe and pathological level of domestic violence. Authors conclude that Women Abuse Screening Tool has acceptable psychometric properties to justify its usage for the assessment of level of domestic violence among pregnant women in Nigeria and other nations with similar socio-cultural backgrounds.

A recent study by Castellani et al. (JAMA 302(23):2573–2579, 2009) describes the population-level effects of the choices of individuals who underwent molecular carrier screening for cystic fibrosis (CF) in Veneto, in the northeastern part of Italy, between 1993 and 2007. We discuss some of the ethical issues raised by the policies and individual choices that are the subject of this study. In particular, (1) we discuss the ethical issues raised by the acquisition of genetic information through antenatal carrier (...) testing; (2) we consider whether by choosing to procreate naturally these couples can harm the resulting child and/or other members of society, and what the moral implications of such harm would be; (3) we consider whether by choosing to avoid natural procreation carrier couples can harm current or future individuals affected by cystic fibrosis; (4) we discuss whether programs that make carrier testing available can be considered eugenic programs.

Background: Screen time among adults represents a continuing and growing problem in relation to health behaviors and health outcomes. However, no instrument currently exists in the literature that quantifies the use of modern screen-based devices. The primary purpose of this study was to develop and assess the reliability of a new screen time questionnaire, an instrument designed to quantify use of multiple popular screen-based devices among the US population. -/- Methods: An 18-item screen-time questionnaire was created to quantify use (...) of commonly used screen devices (e.g. television, smartphone, tablet) across different time points during the week (e.g. weekday, weeknight, weekend). Test-retest reliability was assessed through intra-class correlation coefficients (ICCs) and standard error of measurement (SEM). The questionnaire was delivered online using Qualtrics and administered through Amazon Mechanical Turk (MTurk). -/- Results: Eighty MTurk workers completed full study participation and were included in the final analyses. All items in the screen time questionnaire showed fair to excellent relative reliability (ICCs = 0.50–0.90; all < 0.000), except for the item inquiring about the use of smartphone during an average weekend day (ICC = 0.16, p = 0.069). The SEM values were large for all screen types across the different periods under study. -/- Conclusions: Results from this study suggest this self-administered questionnaire may be used to successfully classify individuals into different categories of screen time use (e.g. high vs. low); however, it is likely that objective measures are needed to increase precision of screen time assessment.

Biomarker-based predictive tests for subjectively asymptomatic Alzheimer’s disease (AD) are utilized in research today. Novel applications of artificial intelligence (AI) promise to predict the onset of AD several years in advance without determining biomarker thresholds. Until now, little attention has been paid to the new ethical challenges that AI brings to the early diagnosis in asymptomatic individuals, beyond contributing to research purposes, when we still lack adequate treatment. The aim of this paper is to explore the ethical arguments put forward (...) for AI aided AD prediction in subjectively asymptomatic individuals and their ethical implications. The ethical assessment is based on a systematic literature search. Thematic analysis was conducted inductively of 18 included publications. The ethical framework includes the principles of autonomy, beneficence, non-maleficence, and justice. Reasons for offering predictive tests to asymptomatic individuals are the right to know, a positive balance of the risk-benefit assessment, and the opportunity for future planning. Reasons against are the lack of disease modifying treatment, the accuracy and explicability of AI aided prediction, the right not to know, and threats to social rights. We conclude that there are serious ethical concerns in offering early diagnosis to asymptomatic individuals and the issues raised by the application of AI add to the already known issues. Nevertheless, pre-symptomatic testing should only be offered on request to avoid inflicted harm. We recommend developing training for physicians in communicating AI aided prediction. (shrink)

Projects of human improvement take both individual and intergenerational forms. The biosciences provide many technologies, including prenatal screening and the latest gene editing techniques, such as CRISPR, that have been viewed as providing the means to human improvement across generations. But who is fit to furnish the next generation? Historically, eugenics epitomizes the science-based attempt to improve human society through distinguishing kinds of people and then implementing social policies—from immigration restriction to sexual sterilization and euthanasia—that influence and even direct (...) what sorts of people populate our future. Despite recognition of the horrors of the eugenic extremes of the past and of the subhumanizing of those sufficiently below appearance or ability norms to be viewed as “defective” or “unfit”, many people continue to be drawn to strands of eugenic thinking.

The objective of the research is to carry out a review of the literature about suicide risk factors in young university students. The methodology used is quantitative descriptive with a bibliometric approach, under the PRISMA method. The search was carried out in three databases: Clarivate Web of Science, MDPI and Taylor and Francis that had the variables of suicide risk factors. Inclusion criteria were used such as: study variables, years 2019 to 2022, published in Spanish and English,scientific reports research results, (...) research with clinical and non-clinical population. After the application of the Boolean operators, the total sample is (n=10360) and after screening with the PRISMA method (n=45). Results: The United States, followed by China and Bangladesh, are the countries that produce the most on the subject. The most frequent risk factors are: depression, anxiety, stress, academic commitments, lack of opportunities, low income and race. The students with the highest suicide rates are in the health area such as medicine and nursing, in addition, there is more suicide intent in women than in men. (shrink)

Markets sit in places and knowledge produced in these places also constitute the very foundation of markets’ viability and market actors’ performative competitive edge. However, not all markets are created equal primarily in the context of their importance in the global economy. Thus conceived, we imagine a world economy or markets populated by people in front of wide computer screens making sense of financial algorithms and derivatives. In a way, here, we see a market that is run by codified knowledge, (...) or scientific knowledge that transcends boundaries. But what about a conception of market that recognizes the production of knowledge in the periphery, and this instance, fish markets, where place-based knowledge marks the contours of engagement of fishmongers to their wider world and yet, concomitantly, also underscores their attachment to place? In this article, in an ethnographic study of four fish markets in a small coastal town in southern Philippine, fishmongers engage with market processes via their production and deployment of vernacular knowledge which is performed in the form of public specialized knowledge, tacit knowledge and network knowledge. In these forms of vernacular knowledge, we become cognizant of the complexities of market processes even in places that are relegated to the margins, where knowledge plays a crucial role in sensing the world and making it lived and real.

Local participation is always beneficial for sustainable action and environmental problems resulting from urban implementation due to the failure of social and institutional change necessary for a successful transformation of rural life to urban life ahead of the rapid movement of the population. Despite good legal practice and comprehensive guidelines, evidence suggests that Environmental Impact Assessment (EIA) or more broadly Environmental, Social and Health Impact Assessment (ESHIA) have not yet been found satisfactory in Nigeria, as the current system amounts (...) to duplication of efforts and cost. However, ESHIA has been developed and integrated to help manage project activities, facilities, and operations sustainably, so that both economic and ecological profits are accrued (sustainable development) or ensure that any development project does not result in excessive deterioration of and/or the irreversible adverse effect on any component of the environment – a recite for sustainable development. A literature review was done by using a variety of search engines including Research Gate, Google Scholar, Academia, Mendeley, SSRN search strategy to retrieve research publications, “grey literature” and expert working group reports. The thrust of this study is to evaluate the potential benefits of ESHIA as a tool for sustainable environmental development. The evaluation and implementation of EIA are one of the strengths of these tools. Indeed, EIA is the first and foremost management tool employed to help mitigate adverse, potential, and associated impacts of proposed major developments in our environment. EIA is a regulatory requirement that is efficiently used to improve performance, project design, enhancing decision-making, and facilitating policy programs in a sustainable environment. An evaluation of the EIA systems reveals several weaknesses of the EIA system. These include the inadequate capacity of EIA approval authorities, deficiencies in screening and scoping, poor EIA quality, insufficient public participation, and weak monitoring, and erratic government policies. Overall, most EIA study rarely meets the objectives of being a project planning tool to contribute to achieving sustainable development and mitigate the impact of the development project. The study recommends some directions for the future to ensure that entire content of the EIA are religiously implemented, review the existing EIA act, increase the expertise of EIA consultants, create a liaison office with an international organisation and with sister agency, ESHIA must enjoy Improved budgetary provision, time latitude, spatial contexts and methodological improvements for outcome measures to achieve results that are relevant to sustainable development by improving project design, enhancing decision making and facilitating policy programs.

Critical-Range Utilitarianism is a variant of Total Utilitarianism which can avoid both the Repugnant Conclusion and the Sadistic Conclusion in population ethics. Yet Standard Critical-Range Utilitarianism entails the Weak Sadistic Conclusion, that is, it entails that each population consisting of lives at a bad well-being level is not worse than some population consisting of lives at a good well-being level. In this paper, I defend a version of Critical-Range Utilitarianism which does not entail the Weak Sadistic Conclusion. (...) This is made possible by a fourth category of absolute value in addition to goodness, badness, and neutrality. (shrink)

Population axiology concerns how to evaluate populations in terms of their moral goodness, that is, how to order populations by the relations “is better than” and “is as good as”. The task has been to find an adequate theory about the moral value of states of affairs where the number of people, the quality of their lives, and their identities may vary. So far, this field has largely ignored issues about uncertainty and the conditions that have been discussed mostly (...) pertain to the ranking of risk-free outcomes. Most public policy choices, however, are decisions under uncertainty, including policy choices that affect the size of a population. Here, we shall address the question of how to rank population prospects—that is, alternatives that contain uncertainty as to which population they will bring about—by the relations “is better than” and “is as good as”. We start by illustrating how well-known population axiologies can be extended to population prospect axiologies. And we show that new problems arise when extending population axiologies to prospects. In particular, traditional population axiologies lead to prospect-versions of the problems that they praised for avoiding in the risk-free settings. Finally, we identify an intuitive adequacy condition that, we contend, should be satisfied by any population prospect axiology, and show how given this condition, the impossibility theorems in population axiology can be extended to (non-trivial) impossibility theorems for population prospect axiology.

Population axiology is the study of the conditions under which one state of affairs is better than another, when the states of affairs in ques- tion may differ over the numbers and the identities of the persons who ever live. Extant theories include totalism, averagism, variable value theories, critical level theories, and “person-affecting” theories. Each of these the- ories is open to objections that are at least prima facie serious. A series of impossibility theorems shows that this is no (...) coincidence: it can be proved, for various sets of prima facie intuitively compelling desiderata, that no axiology can simultaneously satisfy all the desiderata on the list. One’s choice of population axiology appears to be a choice of which intuition one is least unwilling to give up. (shrink)

I defend a radical interpretation of biological populations—what I call population pluralism—which holds that there are many ways that a particular grouping of individuals can be related such that the grouping satisfies the conditions necessary for those individuals to evolve together. More constraining accounts of biological populations face empirical counter-examples and conceptual difficulties. One of the most intuitive and frequently employed conditions, causal connectivity—itself beset with numerous difficulties—is best construed by considering the relevant causal relations as ‘thick’ causal concepts. (...) I argue that the fine-grained causal relations that could constitute membership in a biological population are huge in number and many are manifested by degree, and thus we can construe population membership as being defined by massively multidimensional constructs, the differences between which are largely arbitrary. I end by showing that positions in two recent debates in theoretical biology depend on a view of biological populations at odds with the pluralism defended here. (shrink)

Do cinematic representations of the natural world only put us in further remove from nature? A phenomenological approach shows that nature screened can produce a richer understanding of human–nature relations as these unfold in visual contact. If vision accesses the world in a unique relationship of sight, in which our contact with the world is defined by vision prior to any other interaction, the cinema offers a special setting for a phenomenology that seeks to draw-out the significance of human relations (...) with the world of nature that come before utility or action. A detailed analysis of the opening sequence of Terrence Malick’s The New World demonstrates how the act of viewing positions the viewer in relation to what she sees. This position, prior to action and with the impossibility to act is seen here as an ethical position, a position of responsibility in the Levinasian sense. Merleau-Ponty’s phenomenology of vision is put here to use alongside the hermeneutic phenomenology of Heidegger and the existential responsibility of Levinas, while subverting Levinas’ anthropocentrism and rejecting Heidegger’s limiting view of technology. The approach taken in this essay, of bringing phenomenology into productive and reflexive interaction with ecology and with film is dubbed an “eco-film-phenomenology.”. (shrink)

Whereas recent commentators have suggested that consumer demand, typecasting and marketing lead performers to maintain continuities across films, I argue that cinema has historically made it difficult to subtract performers from roles, leading to relatively constant comportment, and that casting, marketing and audience preference are not only causes but also effects of this. I do so using thought experiments and empirical experiments, for example, by pondering why people say they see Jesus in paintings of him and rarely mention models, but (...) stress that they see actors when encountering photographic stills of performers portraying him. Arguably, this relates to what photographs have historically come to mean, and these meanings would make it difficult for audiences to subtract and not see the actor. Based on such thinking, along with what filmmakers have said and done, and adding to classic accounts of Cavell, Santayana and others, I build the case that cinematic media invite performers to play themselves.

Using the two cases of the Icelandic Health Sector Database and Russian initiatives in biobanking, the article criticizes the view of narratives and imaginaries as a sufficient and unproblematic means of shaping public understanding of genetics and justifying population-wide projects. Narrative representations of national biobanking engage particular imaginaries that are not bound by the universal normative framework of human rights, promote affective thinking, distract the public from recognizing and discussing tangible ethical and socioeconomic issues, and harm trust in science (...) and technology. In the Icelandic case, the presentation of the project in association with national imaginaries concealed its market identity and could lead to the commodification of biodata. In the Russian case, framing in terms of "genetic sovereignty" and "civilizational code" offers pretexts for state securitization. Adherence to normative framework of human rights and public discussion of genetics in an argumentative and factual mode can counter these trends. (shrink)

This paper establishes a Kantian duty against screen overexposure. After defining screen exposure, I adopt a Kantian approach to its morality on the ground that Kant’s notion of duties to oneself easily captures wrongdoing in absence of harm or wrong to others. Then, I draw specifically on Kant’s ‘duties to oneself as an animal being’ to introduce a duty of self-government. This duty is based on the negative causal impact of the activities it regulates on a human being’s mental and (...) physical powers, and, ultimately, on the moral employment of these powers. After doing so, I argue that the duty against screen overexposure is an instance of the duty of self-government. Finally, I consider some objections. (shrink)

By looking at videogame production through a two-vector model of design – a practice determined by the interplay between economic and technological evolution – we argue that shared screen play, as both collaboration and competition, originally functioned as a desirable pattern in videogame design, but has since become problematic due to industry transformations. This is introduced as an example of what we call design vestigiality: momentary loss of a design pattern’s contextual function due to techno-economical evolution.

The concept of population thinking was introduced by Ernst Mayr as the right way of thinking about the biological domain, but it is difficult to find an interpretation of this notion that is both unproblematic and does the theoretical work it was intended to do. I argue that, properly conceived, Mayr’s population thinking is a version of trope nominalism: the view that biological property-types do not exist or at least they play no explanatory role. Further, although population (...) thinking has been traditionally used to argue against essentialism about biological kinds, recently it has been suggested that it may be consistent with at least some forms of essentialism—ones that construe essential properties as relational. I argue that if population thinking is a version of trope nominalism, then, as Mayr originally claimed, it rules out any version of essentialism about biological kinds. (shrink)

Millstein (2009) argues against conceptual pluralism with respect to the definition of “population,” and proposes her own definition of the term.

The concept of population, I argue, does not refer to a natural kind; populations are constructs of biologists variably defined by contexts of inquiry.

Contrary to political and philosophical consensus, we argue that the threats posed by climate change justify population engineering, the intentional manipulation of the size and structure of human populations. Specifically, we defend three types of policies aimed at reducing fertility rates: choice enhancement, preference adjustment, and incentivization. While few object to the first type of policy, the latter two are generally rejected because of their potential for coercion or morally objectionable manipulation. We argue that forms of each policy type (...) are pragmatically and morally justified tools for preventing the harms of global climate change. (shrink)

Contemporary biology has inherited two key assumptions from the Modern Synthesis about the nature of population lineages: sexual reproduction is the exemplar for how individuals in population lineages inherit traits from their parents, and random mating is the exemplar for reproductive interaction. While these assumptions have been extremely fruitful for a number of fields, such as population genetics and phylogenetics, they are increasingly unviable for studying the full diversity and evolution of life. I introduce the “mixture” account (...) of population lineages that escapes these assumptions by dissolving the Modern Synthesis’s sharp line separating reproduction and development and characterizing reproductive integration in population lineages by the ephemerality of isolated subgroups rather than random mating. The mixture account provides a single criterion for reproductive integration that accommodates both sexual and asexual reproduction, unifying their treatment under Kevin de Queiroz’s generalized lineage concept of species. The account also provides a new basis for empirically assessing the effect of random mating as an idealization on the empirical adequacy of population genetic models. (shrink)

Is evidential support transitive? The answer is negative when evidential support is understood as confirmation so that X evidentially supports Y if and only if p(Y | X) > p(Y). I call evidential support so understood “support” (for short) and set out three alternative ways of understanding evidential support: support-t (support plus a sufficiently high probability), support-t* (support plus a substantial degree of support), and support-tt* (support plus both a sufficiently high probability and a substantial degree of support). I also (...) set out two screening-off conditions (under which support is transitive): SOC1 and SOC2. It has already been shown that support-t is non-transitive in the general case (where it is not required that SOC1 holds and it is not required that SOC2 holds), in the special case where SOC1 holds, and in the special case where SOC2 holds. I introduce two rather weak adequacy conditions on support measures and argue that on any support measure meeting those conditions it follows that neither support-t* nor support-tt* is transitive in the general case, in the special case where SOC1 holds, or in the special case where SOC2 holds. I then relate some of the results to Douven’s evidential support theory of conditionals along with a few rival theories. (shrink)

In the age of web 2.0, the university is constantly challenged to re-adapt its ‘old-fashioned’ pedagogies to the new possibilities opened up by digital technologies. This article proposes a rethinking of the relation between university and (digital) technologies by focusing not on how technologies function in the university, but on their constituting a meta-condition for the existence of the university pedagogy of inquiry. Following Ivan Illich’s idea that textual technologies played a crucial role in the inception of the university, we (...) will first show the structural similarities between university thinking and the text as a profanation of the book. Secondly, we describe university thinking as a type of critical thinking based on the materiality of the text-on-the-page, explaining why the text has been at the centre of university pedagogy since the beginning. In the third part, we show how Illich came to see the end of the culture of the text as a challenge for the university, by describing the new features of the text-as-code incompatible with the idea of reading as study. Finally, we challenge this pessimistic reading of Illich’s and end with a call for a profanatory pedagogy of digital technologies that could mirror the revolutionary thinking behind the mediaeval invention of the text.

The present study collected a larger set of three-dimensional data on human crania from the Kofun period (as well as from previous periods, i.e., the Jomon and Yayoi periods) in the Japanese archipelago (AD 250 to around 700) than previous studies. Three-dimensional geometric morphometrics were employed to investigate human migration patterns in finer-grained phases. These results are consistent with those of previous studies, although some new patterns were discovered. These patterns were interpreted in terms of demic diffusion, archaeological findings, and (...) historical evidence. In particular, the present results suggest the presence of a gradual geological cline throughout the Kofun period, although the middle period did not display such a cline. This discrepancy might reflect social changes in the middle Kofun period, such as the construction of keyhole-shaped mounds in the peripheral regions. The present study implies that a broader investigation with a larger sample of human crania is essential to elucidating macro-level cultural evolutionary processes. (shrink)

Concerns about population ageing apply to both developed and many developing countries and it has turned into a global issue. In the forthcoming decades the population ageing is likely to become one of the most important processes determining the future society characteristics and the direction of technological development. The present paper analyzes some aspects of the population ageing and its important consequences for particular societies and the whole world. Basing on this analysis, we can draw a conclusion (...) that the future technological breakthrough is likely to take place in the 2030s (which we define as the final phase of the Cybernetic Revolution). In the 2020s – 2030s we will expect the upswing of the forthcoming sixth Kondratieff wave, which will introduce the sixth technological paradigm (system). All those revolutionary technological changes will be connected, first of all, with breakthroughs in medicine and related technologies. We also present our ideas about the financial instruments that can help to solve the problem of pension provision for an in-creasing elderly population in the developed countries. We think that a more purposeful use of pension funds' assets together with an allocation (with necessary guarantees) of the latter into education and upgrading skills of young people in developing countries, perhaps, can partially solve the indicated problem in the developed states.

The causes of prehistoric inter-group violence have been a subject of long-standing debate in archaeology, an- thropology, and other disciplines. Although population pressure has been considered as a major factor, due to the lack of available prehistoric data, few studies have directly examined its effect so far. In the present study, we used data on skeletal remains from the middle Yayoi period of the Japanese archipelago, where archaeologists argued that an increase of inter-group violence in this period could be (...) explained by a population-pressure hy- pothesis. We quantitatively examine the effect of population pressure on the frequency of inter-group violence by compiling an exhaustive data set. We collected demographic information based on burial jars (kamekan) and the frequency of violence based on the ratio of injured individuals. The results are consistent with the hypothesis, i. e., high population density can promote inter-group violence. (shrink)

The church-funded CARFO or KARFO (Afrikaans Christian Filmmaking Organisation) was established in 1947, and aimed to ‘[socialise] the newly urbanized Afrikaner into a Christian urban society’ (Tomaselli 1985:25; Paleker 2009:45). This initiative was supported and sustained by the Dutch Reformed Church (DRC), which had itself been part of the sociopolitical and ideological fabric of Afrikaans religious life for a while and would guide Afrikaners through tensions between religious conservatism and liberalism and into apartheid. Given Afrikaans cinema’s ties with Christian religious (...) and political conservatism, we explore the role – even the centrality – of the Afrikaans church in cultural activity before 1994, and then after 1994. Here, Afrikaans church is an inclusive term that brings together various denominations of Afrikaans-speaking churches, but which mainly suggests the domination of the DRC. After establishing the role of the Afrikaans church in the way described above, we move towards the primary focus of our study: exploring the representation of clergy in the contemporary Afrikaans film Faan se Trein in order to describe certain theological implications of this representation. With reference to Faan se Trein, our article notes and comments on the shifts that have occurred in clergy representation in Afrikaans cinema over the past decades. Osmer’s four tasks of practical theology, namely, descriptive, interpretive, normative and strategic are used for theological reflection. With due contextual reference to Afrikaans film dramas such as Broer Matie [Brother Matie], Saak van Geloof [A Matter of Faith], Roepman [Stargazer], Stilte [Silence], Suiderkruis [Southern Cross] and Faan se Trein, we arrive at some preliminary conclusions about the representation of clergy in mainly contemporary Afrikaans cinema.

The practice of screening potential users of reproductive services is of profound social and political significance. Access screening is inconsistent with the principles of equality and self-determination, and violates individual and group human rights. Communities that strive to function in accord with those principles should not permit access screening, even screening that purports to be a benign exercise of professional discretion. Because reproductive choice is controversial, regulation by law may be required in most jurisdictions to provide (...) effective protection for reproductive rights. In Canada, for example, equal access can, and should be, guaranteed by federal regulations imposing strict conditions on the licences of fertility clinics. (shrink)

Analysing the demands of global justice for the distribution of resources is a complex task and requires consideration of a broad range of issues. Of particular relevance is the effect that different distributions will have on global population growth and individual welfare. Since changes in the consumption and distribution of resources can have major effects on the welfare of the global population, and the rate at which it increases, it is important to establish meaningful principles to ensure a (...) just distribution of resources. In order to establish such principles we must consider the scope of any reproductive rights, and rights to other goods, such as food and health care, as well as examine the extent of duties correlating to those rights. In addition to the impact that distributions of global goods have on the welfare of current generations, it is also important to consider what duties we have, if any, to future generations. -/- The final version of this paper is available to download here: http://dx.doi.org/10.1002/9780470015902.a0024140.

In “Risk Based Passenger Screening in Aviation Security: Implications and Variants of a New Paradigm”, Sebastian Weydner-Volkmann describes the current paradigm shift from ‘traditional’ forms of screening to ‘risk based passenger screening’ (RBS) in aviation security. This paradigm shift is put in the context of the wider historical development of risk management approaches. Through a discussion of Michel Foucault, Herfried Münkler and Ulrich Beck, Weydner-Volkmann analyses the shortcomings of such approaches in public security policies, which become especially (...) evident in the aviation security context. As he shows, the turn towards methods of RBS can be seen as an attempt to address a trade-off ‘trilemma’ between the effective provision of security, the implied costs for industry and passengers, and the ethical, legal and societal implications of the screening procedures. In order to analyse foreseeable outcomes of embracing RBS, he differentiates three prototypical variants of the new paradigm on the basis of their main referent and rationale. For each variant, he then subsequently assesses the implications for the ‘trilemma’, after having unveiled the criteria of analysis that will necessarily have to be followed within a serious appraisal of RBS methods.

Millikan’s (1984. Language, Thought, and Other Biological Categories: New Foundations for Realism. MIT Press) selected effects theory of functions states that functions are effects for which the ancestors of a trait were selected for. As the function is an effect a thing’s ancestors produced, only things that are reproductions in some sense can have functions. Against this reproduction requirement, Garson (2019. What Biological Functions Are and Why They Matter. Cambridge University Press) argues that not only processes of differential reproduction but (...) also processes of differential persistence can lead to new functions. Since such “persistence functions” have the same explanatory power as traditional selected effects functions, selected effects theorists should include them in their theory. In this paper, I will defend Millikan’s theory against this argument. I will show that the proponents of the generalized theory have yet to provide a working notion of populations that avoids a liberality problem. Further, I will argue that persistence functions are at best a marginal case of functions due to their restricted explanatory power. (shrink)

The article proposes to model the phenomenon of the cell phone as a wall-window. This model aims at explicating some of the perceptions and experiences associated with cellular technology. The wall-window model means that the cell phone simultaneously separates the user from the physical surroundings (the wall), and connects the user to a remote space (the window). The remote space may be where the interlocutor resides or where information is stored (e.g. the Internet). Most cell phone usage patterns are modeled (...) as a single dimension according to the level of distraction or attention of the user. In order to accommodate nuanced situations such as augmented reality, I suggest a two-dimensional layout: the wall-window. The wall represents the attention to the immediate physical environment, while the window represents the attention to a remote space. The wall-window model further evolves once a screen is woven into this layout. This addition is easily understood due to the screen’s etymology, which is associated with the concepts of shield or barrier. From a technical perspective, the screen has become an integral part of the cell phone. Furthermore, a screen itself is both a wall and a window. Lastly, once a cell phone is supplemented with a screen, it is easier to refer to it as media. And again, media fits into the wall-window model. (shrink)

Suppose a rational agent S has some evidence E that bears on p, and on that basis makes a judgment about p. For simplicity, we’ll normally assume that she judges that p, though we’re also interested in cases where the agent makes other judgments, such as that p is probable, or that p is well-supported by the evidence. We’ll also assume, again for simplicity, that the agent knows that E is the basis for her judgment. Finally, we’ll assume that the (...) judgment is a rational one to make, though we won’t assume the agent knows this. Indeed, whether the agent can always know that she’s making a rational judgment when in fact she is will be of central importance in some of the debates that follow. (shrink)

This thesis consists of several independent papers in population ethics. I begin in Chapter 1 by critiquing some well-known 'impossibility theorems', which purport to show there can be no intuitively satisfactory population axiology. I identify axiological vagueness as a promising way to escape or at least mitigate the effects of these theorems. In particular, in Chapter 2, I argue that certain of the impossibility theorems have little more dialectical force than sorites arguments do. From these negative arguments I (...) move to positive ones. In Chapter 3, I justify the use of a 'veil of ignorance', starting from three more basic normative principles. This leads to positive arguments for various kinds of utilitarianism - the best such arguments I know. But in general the implications of the veil depend on how one answers what I call 'the risky existential question': what is the value to an individual of a chance of non-existence? I chart out the main options, and raise some puzzles for non-comparativism, the view that life is incomparable to non-existence. Finally, in Chapter 4, I consider the consequences for population ethics of the idea that what is normatively relevant is not personal identity, but a degreed relation of psychological connectedness. In particular, I pursue a strategy based in population ethics for understanding the controversial 'time-relative interests' account of the badness of death. (shrink)

The standard perception of the dichotomy between population thinking and essentialism (typological thinking) in evolutionary economics descends from the golden age of the neo-Darwinian Synthesis. Over the last few decades the received view on population thinking has been seriously challenged in biology and its philosophy. First, the strong version of population thinking that banishes essentialism witnessed important tensions stemming from the ontological status of species. These tensions have been amplified by the demise of positivism and the rise (...) of a new essentialism in philosophy of science. Second, the soft version that transforms the opposition between population thinking and essentialism to the dichotomy between ultimate and proximate causation has led to contradictory interpretations regarding the locus of ultimate causes. Taking stock of the previous discussion the paper addresses the limits to population thinking in the socio-economic realm. The upshot is that without denying the important achievements made by the application of population thinking in sub-disciplines like industrial dynamics and economic anthropology, the idea to generalize these applications into the whole socio-economic realm is problematic. The aforementioned achievements cannot come to grips with the structural aspects of capitalism, its different periods (e.g. the contemporary finance-led capitalism) and its geographical varieties. The resulting gap points to the importance of structural analysis (essentialism) and evolutionary political economy. The latter is distinguished from the rest of evolutionary economics by its project to go beyond the surface of economic phenomena and to critically analyze their underlying social structures.

This paper aims to state the obvious – the commonsense, rational approach to child-producing. We have no general obligation to promote either the “general happiness” or the equalization of this and that. We have children if we want them, if their life prospects are decent – and if we can afford them, which is a considerable part of their life prospects being OK – and provided that in doing so we do not inflict injury on others. It’s extremely difficult to (...) do this latter, but affording them, in rich countries, is another matter. With that qualification, by and large people should just go ahead and have (or not have) children – as many as they think they want and can handle – as it suits them. (shrink)

Values are incommensurable when they cannot be measured on a single cardinal scale. Many philosophers suggest that incommensurability can help us solve the problems of population ethics. I agree. But some philosophers claim that populations bear incommensurable values merely because they contain different numbers of people, perhaps within some range. I argue that mere differences in how many people exist, even within some range, do not suffice for incommensurability. I argue that the intuitive neutrality of creating happy people is (...) better captured by a version of average utilitarianism. But this view is problematic. So I suggest a version of total utilitarianism that avoids the repugnant conclusion by appealing to incommensurable dimensions of wellbeing. (shrink)

According to the person-affecting restriction, one distribution of welfare can be better than another only if there is someone for whom it is better. Extant problems for the person-affecting restriction involve variable-population cases, such as the nonidentity problem, which are notoriously controversial and difficult to resolve. This paper develops a fixed-population problem for the person-affecting restriction. The problem reveals that, in the presence of incommensurable welfare levels, the person-affecting restriction is incompatible with minimal requirements of impartial beneficence even (...) in fixed-population contexts.

The genealogy-based classificatory programs of Kant and Darwin are briefly discussed for context. It is detailed how in biology there is no unambiguous term to reference infraspecific-level descent-based divisions. The term lineage population is introduced and defined for analytic purposes as one of a set of inter-fertile divisions of organisms into which members are arranged by propinquity of descent. It is argued that the lineage population concept avoids the ambiguities associated with related biological and anthropological concepts and polysemes (...) such as population, ethnicity, and race. Other terms and concepts, such as form, cline, cluster, geographic population, breeding population, genetic population, breed, species, subspecies, ancestry, geographic ancestry, biogeographic ancestry, ancestral population, ancestry population, natural division, and population lineage, are discussed in relation to this concept. It is concluded that the lineage population concept is a useful analytic tool which describes, in line with the Kantian/Darwinian perspective, an interesting class of biological variation. (shrink)

It is well known that the probabilistic relation of confirmation is not transitive in that even if E confirms H1 and H1 confirms H2, E may not confirm H2. In this paper we distinguish four senses of confirmation and examine additional conditions under which confirmation in different senses becomes transitive. We conduct this examination both in the general case where H1 confirms H2 and in the special case where H1 also logically entails H2. Based on these analyses, we argue that (...) the Screening-Off Condition is the most important condition for transitivity in confirmation because of its generality and ease of application. We illustrate our point with the example of Moore’s “proof” of the existence of a material world, where H1 logically entails H2, the Screening-Off Condition holds, and confirmation in all four senses turns out to be transitive.

Given the deep disagreement surrounding population axiology, one should remain uncertain about which theory is best. However, this uncertainty need not leave one neutral about which acts are better or worse. We show that as the number of lives at stake grows, the Expected Moral Value approach to axiological uncertainty systematically pushes one towards choosing the option preferred by the Total and Critical Level views, even if one’s credence in those theories is low.

Research on the folk psychology of free will suggests that people believe free will is incompatible with determinism and that human decision-making cannot be exhaustively characterized by physical processes. Some suggest that certain elements of Western cultural history, especially Christianity, have helped to entrench these beliefs in the folk conceptual economy. Thus, on the basis of this explanation, one should expect to find three things: (1) a significant correlation between belief in dualism and belief in free will, (2) that people (...) with predominantly incompatibilist commitments are likely to exhibit stronger dualist beliefs than people with predominantly compatibilist commitments, and (3) people who self-identify as Christians are more likely to be dualists and incompatibilists than people who do not self-identify as Christians. We present the results of two studies (n = 378) that challenge two of these expectations. While we do find a significant correlation between belief in dualism and belief in free will, we found no significant difference in dualist tendencies between compatibilists and incompatibilists. Moreover, we found that self-identifying as Christian did not significantly predict preference for a particular metaphysical conception of free will. This calls into question assumptions about the relationship between beliefs about free will, dualism, and Christianity. (shrink)

Many epidemics consist in individuals spreading infection to others. From the population perspective, they also have population characteristics important in modeling, explaining, and intervening in epidemics. I analyze epidemiology’s contemporary population perspective through the example of epidemics by examining two central principles attributed to Geoffrey Rose: a distinction between the causes of cases and the causes of incidence, and between “high-risk” and “population” strategies of prevention. Both principles require revision or clarification to capture the sense in (...) which they describe distinct perspectives on the same phenomenon, each perspective capturing a different level of contrastive analysis.

Evolutionary biology is a field currently animated by much discussion concerning its conceptual foundations. On the one hand, we have supporters of a classical view of evolutionary theory, whose backbone is provided by population genetics and the so-called Modern Synthesis (MS). On the other hand, a number of researchers are calling for an Extended Synthe- sis (ES) that takes seriously both the limitations of the MS (such as its inability to incorporate developmental biology) and recent empirical and theoretical research (...) on issues such as evolvability, modularity, and self-organization. In this article, I engage in an in-depth commentary of an influential paper by population geneticist Michael Lynch, which I take to be the best defense of the MS-population genetics position published so far. I show why I think that Lynch’s arguments are wanting and propose a modification of evolutionary theory that retains but greatly expands on population genetics. (shrink)

We present an abstract social aggregation theorem. Society, and each individual, has a preorder that may be interpreted as expressing values or beliefs. The preorders are allowed to violate both completeness and continuity, and the population is allowed to be infinite. The preorders are only assumed to be represented by functions with values in partially ordered vector spaces, and whose product has convex range. This includes all preorders that satisfy strong independence. Any Pareto indifferent social preorder is then shown (...) to be represented by a linear transformation of the representations of the individual preorders. Further Pareto conditions on the social preorder correspond to positivity conditions on the transformation. When all the Pareto conditions hold and the population is finite, the social preorder is represented by a sum of individual preorder representations. We provide two applications. The first yields an extremely general version of Harsanyi's social aggregation theorem. The second generalizes a classic result about linear opinion pooling. (shrink)

Non-Archimedean population axiologies – also known as lexical views – claim (i) that a sufficient number of lives at a very high positive welfare level would be better than any number of lives at a very low positive welfare level and/or (ii) that a sufficient number of lives at a very low negative welfare level would be worse than any number of lives at a very high negative welfare level. Such axiologies are popular because they can avoid the (Negative) (...) Repugnant Conclusion and satisfy the adequacy conditions given in the central impossibility result in population axiology due to Gustaf Arrhenius. I provide a novel argument against them which appeals to the way that good and bad lives can intuitively outweigh one other. (shrink)

The technological virtual converges with our contemporary existence in a multitude of ways, which suggests a need to interrogate the question of the virtual existentially. Merleau-Ponty’s existential phenomenological account of embodiment is invaluable in this regard because the virtual is encountered from the basis of the facticity of the embodied individual – a facticity that is closely related to perception and motor intentionality. The current article argues that these characteristics of the body-subject should be taken into consideration in order to (...) develop a clearer description of the virtual. However, beyond an embodied account that relates to early technologies, Merleau-Ponty also presents through his concept of the flesh a novel avenue for the ontological investigation of the virtual. The flesh describes the intertwining of the body-subject and the world, which is suggestive of a new account of the individual’s sensibility in relation to the virtual. An original concept is suggested to describe the existential-ontological structure of the virtual: The embodied screen. The embodied screen as neologism presents an alternative conceptualisation of the coincidence of the body-subject (who understands the world spatially) with the virtual (as non-spatial). By tracing imaginative signification and embodied habitude in terms of the virtual, this article suggests certain existential implications of the virtual for contemporary being. (shrink)

I argue elsewhere (Roche 2014) that evidence of evidence is evidence under screening-off. Tal and Comesaña (2017) argue that my appeal to screening-off is subject to two objections. They then propose an evidence of evidence thesis involving the notion of a defeater. There is much to learn from their very careful discussion. I argue, though, that their objections fail and that their evidence of evidence thesis is open to counterexample.

This paper sets out a novel response to the ‘screening off problem’ for naïve realism. The aim is to resist the claim (which many naïve realists accept) that the kind of experience involved in hallucinating also occurs during perception, by arguing that there are causal constraints that must be met if an hallucinatory experience is to occur that are never met in perceptual cases. Notably, given this response, it turns out that, contra current orthodoxy, naïve realists need not adopt (...) any particular view about the psychological nature of hallucinatory experience to handle the screening off problem. Consequently, room opens up for naïve realists to endorse whatever theory of hallucinatory experience seems to best capture the distinctive nature of such episodes. (shrink)
