Ever since the early days of quantum mechanics it has been suggested that consciousness could be linked to the collapse of the wave function. However, no detailed account of such an interplay is usually provided. In this paper we present an objective collapse model where the collapse operator depends on integrated information, which has been argued to measure consciousness. By doing so, we construct an empirically adequate scheme in which superpositions of conscious states are dynamically suppressed. Unlike other proposals in (...) which “consciousness causes the collapse of the wave function,” our model is fully consistent with a materialistic view of the world and does not require the postulation of entities suspicious of laying outside of the quantum realm.

You don't say much about who you are teaching, or what subject you teach, but you do seem to see a need to justify what you are doing. Perhaps you're teaching underprivileged children, opening their minds to possibilities that might otherwise never have occurred to them. Or maybe you're teaching the children of affluent families and opening their eyes to the big moral issues they will face in life — like global poverty, and climate change. If you're doing something like (...) this, then stick with it. Giving money isn't the only way to make a difference. (shrink)

Background/purpose – This study analyzed the contribution of three mentorship practices relatively and cumulatively to the research productivity of early-career academics in the field of educational psychology in universities. The study was conducted in the South- South region of Nigeria. -/- Materials/methods – The research method adopted was the quantitative approach, following the ex-post facto research design. The study’s population covered 723 early-career researchers (ECRs) in educational psychology distributed across 19 universities located in South-South Nigeria. The “Mentorship Practices and Research (...) Productivity Questionnaire” (MPRPQ) was the instrument used for data collection. The questionnaire was designed by the researchers and then validated by three experts. Reliability analysis was performed using the Cronbach approach with estimates of .80, .79, .87, and .91 obtained for the four clusters. Primary data were collected from the field after copies of the instrument had been administered to respondents. -/- Results – Mentorship practices were generally revealed to significantly contribute to the research productivity of ECRs in educational psychology in universities. Specifically, the adoption of cloning and apprenticeship approaches to mentorship contributed substantially to the ECRs’ research productivity. However, the study highlighted that nurturing contributed only negligibly to the ECRs’ research productivity. -/- Conclusion – Mentorship practices are important determinants to the research productivity of early-career educational psychologists. In order to boost the productive research capacities of ECRs, there is a need for institutions to strengthen their mentorship practices. (shrink)

Public discussions of political and social issues are often characterized by deep and persistent polarization. In social psychology, it’s standard to treat belief polarization as the product of epistemic irrationality. In contrast, we argue that the persistent disagreement that grounds political and social polarization can be produced by epistemically rational agents, when those agents have limited cognitive resources. Using an agent-based model of group deliberation, we show that groups of deliberating agents using coherence-based strategies for managing their limited resources tend (...) to polarize into different subgroups. We argue that using that strategy is epistemically rational for limited agents. So even though group polarization looks like it must be the product of human irrationality, polarization can be the result of fully rational deliberation with natural human limitations. (shrink)

Nincs még egy délkelet-ázsiai ország, mely oly markáns hatást gyakorolt volna a huszadik század történelméről kialakult képükre, mint az egyesítésének 40. évfordulóját idén ünneplő Vietnami Szocialista Köztársaság. Ezt persze több évtizedes háborús szenvedéseinek és az amerikai tömegkultúra ezt nemritkán sajátosan közvetítő, de mindenképpen globális kisugárzással bíró üzeneteinek „köszönheti”.1 Vietnam viharos történelmi közelmúltja máig rányomja bélyegét a vele kapcsolatos képünkre, jóllehet, az említett 1975. évi – az északi és déli országrész egyesülésével járó – újjászületés óta itt sem állt meg az idő. (...) A Lengyelországnál alig nagyobb Vietnam 2015-re a Föld 13. legnépesebb országa lett, és korábbi elképesztő szegénységének enyhítésében is – bár európai szemmel szerénynek tűnhető, de – határozott javulást könyvelhet el.2 Napjainkban – ahogy azt a távol-keleti nemzetközi kapcsolatok alakulásánál megszokhattuk – a Kínai Népköztársaság hatalmi súlyának fokozódása és regionális ambíciói helyezték új megvilágításba a „legmagyarabbnak” tekintett3 délkelet-ázsiai nép lehetséges szerepét. Ez egyszersmind az alapdilemmát is azonnal eszünkbe juttatja: Vietnam múlt századi tragédiáját a vele kapcsolatos nagyhatalmi ambíciók idézték elő. Igaz, az ország bizonyította ellenálló képességét, és a 21. századra változott valamelyest a szereposztás is, Délkelet-Ázsia hosszú távú jövője a nemzetközi rendszerben továbbra is bizonytalan. Az alábbiakban számvetésre vállalkozunk Vietnam helyzetéről és lehetséges pozícióiról korunk vezető hatalmainak kelet-ázsiai játszmáiban. (shrink)

The standard view says that epistemic normativity is normativity of belief. If you’re an evidentialist, for example, you’ll think that all epistemic reasons are reasons to believe what your evidence supports. Here we present a line of argument that pushes back against this standard view. If the argument is right, there are epistemic reasons for things other than belief. The argument starts with evidentialist commitments and proceeds by a series of cases, each containing a reason. As the cases progress, the (...) reasons change from counting in favor of things like having a belief to things like performing ordinary actions. We argue that each of those reasons is epistemic. If the argument succeeds, we should think there are epistemic reasons to consider hypotheses, conduct thought and physical experiments, extend one’s evidence, and perform mundane tasks like eating a sandwich, just as there are epistemic reasons to believe what one’s evidence supports.

Political development is basically a process that is concerned with the improvement of institutions, attitudes and values that form the political system of a society or nation. In Nigeria, a critical assessment has revealed that despite the nation’s abundant human and natural resources, her citizens are subjected to abject poverty. Thus, this paper sets study is to assess the level of political development in the country and give reasons for establishing strong institutions. This paper concludes that the nation’s political development (...) is hampered by factors like imposition of unrealistic policies on citizens and poor assessment/implementation of such policies, problem of socio-economic inequalities, historical challenge, corruption and mismanagement of resources and lack of credible leadership among others. This work, adopting a method of critical analysis, concludes that in order to tackle these setbacks and ensure sustainable political development in the nation there is urgent need for strong institutions..

[Newspaper Opinion] Before the COVID-19 pandemic and the accompanying fall in oil prices, a carbon price would have been immediately painful for the countries that imposed it, but far better for everyone over the longer term. In this unprecedented moment, introducing a carbon price would be beneficial both now and for the future.

Religion and culture are interwoven and this can be seen among the Oron people in their use of the shrine as a socio-cultural and ethical institution. The shrine is an embodiment and the symbol of the very traditional religion of the people. As such, the shrine serves as a medium through which the norms, values, ethics, taboos, and morals are taught and enforced. There is also a great relationship between religion and justice as the shrine (Afi/Obio) as an ethical institution (...) serves as a tribunal of justice by the deities, divinities, and ancestors under the guidance and administration of the priest in tackling and resolving criminal activities, disputes as well as restoring social order and justice in Oron traditional society. The Oron Afi/Obio (Shrine) method of administering justice is beyond the Empirical application of the modern judiciary system that relies on physical facts and shreds of evidence, while the shrine, also, uses spiritual methods that involve Oath taking, incantation and necromancy. Globalization rather than modifying the lapses and loopholes of this system in the parlance of morality, ethics, and health has led to its abolition and break down. This work adopts the qualitative method. This work as primary research uses the conflict theory, phenomenological and Historical method. It identifies globalization as a threat to the traditional justice system and recommends that the shrine is a multi-faceted institution whose function can be adopted and applied to the Nigerian legal system where there is no or little evidence and oath swearing for politicians in our contemporary society.

The is-ought gap is Hume’s claim that we can’t get an ‘ought’ from just ‘is’s. Prior (“The Autonomy of Ethics,” 1960) showed that its most straightforward formulation, a staple of introductory philosophy classes, fails. Many authors attempt to resurrect the claim by restricting its domain syntactically or by reformulating it in terms of models of deontic logic. Those attempts prove to be complex, incomplete, or incorrect. I provide a simple reformulation of the is-ought gap that closely fits Hume’s description of (...) it. My formulation of the gap avoids the proposed counterexamples from Prior and offers a natural explanation of why they seem compelling. Moreover, I show that my formulation of the gap is guaranteed by standard theories of the semantics of normative terms, and that provides a more general reason to accept it. (shrink)

We motivate a picture of social epistemology that sees forgetting as subject to epistemic evaluation. Using computer simulations of a simple agent-based model, we show that how agents forget can have as large an impact on group epistemic outcomes as how they share information. But, how we forget, unlike how we form beliefs, isn’t typically taken to be the sort of thing that can be epistemically rational or justified. We consider what we take to be the most promising argument for (...) this claim and find it lacking. We conclude that understanding how agents forget should be as central to social epistemology as understanding how agents form beliefs and share information with others. (shrink)

Freedom of speech has traditionally been a cause championed by the left and liberal side of the political spectrum, against conservatives who have tried to limit the expression of radical ideas. Here are three examples from the United States: 1) When I was appointed to Princeton University in 1999, Steve Forbes, whose father had endowed the university’s Forbes College, called for my appointment to be rescinded, and pledged that he would not donate to the university as long as I was (...) on the faculty.

Agent-based models have played a prominent role in recent debates about the merits of democracy. In particular, the formal model of Lu Hong and Scott Page and the associated “diversity trumps ability” result has typically been seen to support the epistemic virtues of democracy over epistocracy (i.e., governance by experts). In this paper we first identify the modeling choices embodied in the original formal model and then critique the application of the Hong-Page results to philosophical debates on the relative merits (...) of democracy. In particular we argue that the “best-performing agents” in Hong-Page model should not be interpreted as experts. We next explore a closely related model in which best-performing agents are more plausibly seen as experts and show that the diversity trumps ability result fails to hold. However, with changes in other parameters (such as the deliberation dynamic) the diversity trumps ability result is restored. The sensitivity of this result to parameter choices illustrates the complexity of the link between formal modeling and more general philosophical claims; we use this debate as a platform for a more general discussion of when and how agent-based models can contribute to philosophical discussions.

The Hong and Page ‘diversity trumps ability’ result has been used to argue for the more general claim that a diverse set of agents is epistemically superior to a comparable group of experts. Here we extend Hong and Page’s model to landscapes of different degrees of randomness and demonstrate the sensitivity of the ‘diversity trumps ability’ result. This analysis offers a more nuanced picture of how diversity, ability, and expertise may relate. Although models of this sort can indeed be suggestive (...) for diversity policies, we advise against interpreting such results overly broadly. (shrink)

Do university ethics classes influence students’ real-world moral choices? We aimed to conduct the first controlled study of the effects of ordinary philosophical ethics classes on real-world moral choices, using non-self-report, non-laboratory behavior as the dependent measure. We assigned 1332 students in four large philosophy classes to either an experimental group on the ethics of eating meat or a control group on the ethics of charitable giving. Students in each group read a philosophy article on their assigned topic and optionally (...) viewed a related video, then met with teaching assistants for 50-minute group discussion sections. They expressed their opinions about meat ethics and charitable giving in a follow-up questionnaire (1032 respondents after exclusions). We obtained 13,642 food purchase receipts from campus restaurants for 495 of the students, before and after the intervention. Purchase of meat products declined in the experimental group (52% of purchases of at least $4.99 contained meat before the intervention, compared to 45% after) but remained the same in the control group (52% both before and after). Ethical opinion also differed, with 43% of students in the experimental group agreeing that eating the meat of factory farmed animals is unethical compared to 29% in the control group. We also attempted to measure food choice using vouchers, but voucher redemption rates were low and no effect was statistically detectable. It remains unclear what aspect of instruction influenced behavior. (shrink)

There is too much that we do not know about COVID-19. The longer we take to find it out, the more lives will be lost. In this paper, we will defend a principle of risk parity: if it is permissible to expose some members of society (e.g. health workers or the economically vulnerable) to a certain level of ex ante risk in order to minimize overall harm from the virus, then it is permissible to expose fully informed volunteers to a (...) comparable level of risk in the context of promising research into the virus. We apply this principle to three examples of risky research: skipping animal trials for promising treatments, human challenge trials to speed up vaccine development, and low-dose controlled infection or “variolation.” We conclude that if volunteers, fully informed about the risks, are willing to help fight the pandemic by aiding promising research, there are strong moral reasons to gratefully accept their help. To refuse it would implicitly subject others to still graver risks. (shrink)

Polarization is a topic of intense interest among social scientists, but there is significant disagreement regarding the character of the phenomenon and little understanding of underlying mechanics. A first problem, we argue, is that polarization appears in the literature as not one concept but many. In the first part of the article, we distinguish nine phenomena that may be considered polarization, with suggestions of appropriate measures for each. In the second part of the article, we apply this analysis to evaluate (...) the types of polarization generated by the three major families of computational models proposing specific mechanisms of opinion polarization.

In order to understand the transmission of a disease across a population we will have to understand not only the dynamics of contact infection but the transfer of health-care beliefs and resulting health-care behaviors across that population. This paper is a first step in that direction, focusing on the contrasting role of linkage or isolation between sub-networks in (a) contact infection and (b) belief transfer. Using both analytical tools and agent-based simulations we show that it is the structure of a (...) network that is primary for predicting contact infection—whether the networks or sub-networks at issue are distributed ring networks or total networks (hubs, wheels, small world, random, or scale-free for example). Measured in terms of time to total infection, degree of linkage between sub-networks plays a minor role. The case of belief is importantly different. Using a simplified model of belief reinforcement, and measuring belief transfer in terms of time to community consensus, we show that degree of linkage between sub-networks plays a major role in social communication of beliefs. Here, in contrast to the case of contract infection, network type turns out to be of relatively minor importance. What you believe travels differently. In a final section we show that the pattern of belief transfer exhibits a classic power law regardless of the type of network involved. (shrink)

Religious tourism is as old as religion itself and consequently, it is the oldest form of tourism in the world. Most religions have holy places that people visit from time to time for several reasons. This work examines the Ababa carnival which involves faith- activities, but in a heightened form. It involves pilgrimages to the Ababa holy shrine in Esin Ufot Eyo-Abasi in Oron. This work identifies as a problem, the lack of basic infrastructures and non-patriotic and neglecting attitudes of (...) Nigerians towards their indigenous religious tourism development, as they are so much involved in faith-based activities and travels to Israel, Mecca, Rome among several others. It adopts the Phenomenological method in a Culture Area of Oron. As primary research, it will rely on oral interviews and secondary materials from the libraries and the internet. The findings indicate that the positive effects of indigenous faith-based religious tourism such as Ababa are yet to be used in developing Oron and Nigeria as found in other parts of the world such as Israel, Saudi Arabia, and Italy. This work concludes that traditional religious tourism can be used as a tool for National Development and unity of Nigeria. As a recommendation it calls on the government who sponsors individuals and particular religious groups on pilgrimages, to divert such funds and invest in infrastructural development in Oron to attract tourists to the area and as well develop traditional religious tourism of Nigeria, as this will reduce poverty and create employment opportunities.

The position of this paper is that the political developments in Nigeria has bearing with Protagoras’ “man is the measure”. This dictum simply implies humanism. It is based on this that this work posits that humanism is what underlies and informs the political developments in Nigeria.

Nigerians, in which its failure has resulted in the political developments experienced within the Nigerian-nation states. This conclusion is reached through critical analysis and evaluation.

A scientific community can be modeled as a collection of epistemic agents attempting to answer questions, in part by communicating about their hypotheses and results. We can treat the pathways of scientific communication as a network.

Here we build on previous work, both our own and others’, in (...) order to get a firmer grasp on precisely which features of scientific communities interact with which features of scientific questions in order to influence epistemic outcomes.

ABSTRACT This article distinguishes nine senses of polarization and provides formal measures for each one to refine the methodology used to describe polarization in distributions of attitudes. Each distinct concept is explained through a definition, formal measures, examples, and references. We then apply these measures to GSS data regarding political views, opinions on abortion, and religiosity—topics described as revealing social polarization. Previous breakdowns of polarization include domain-specific assumptions and focus on a subset of the distribution’s features. This has conflated multiple, (...) independent features of attitude distributions. The current work aims to extract the distinct senses of polarization and demonstrate that by becoming clearer on these distinctions we can better focus our efforts on substantive issues in social phenomena.

The fear that business corporations have claimed unwarranted constitutional protections which have entrenched corporate power has produced a broad social movement demanding that constitutional rights be restricted to human beings and corporate personhood be abolished. We develop a critique of these proposals organized around the three salient rationales we identify in the accompanying narrative, which we argue reflect a narrow focus on large business corporations, a misunderstanding of the legal concept of personhood, and a failure to distinguish different kinds of (...) constitutional rights and the reasons for assigning them. Corporate personhood and corporate constitutional rights are not problematic per se once these notions are decoupled from biological, metaphysical, or moral considerations. The real challenge is that we need a principled way of thinking about the priority of human over corporate persons which does not reduce the efficacy of corporate institutions or harm liberal democracies.

Epistemic justifications for democracy have been offered in terms of two different aspects of decision-making: voting and deliberation, or ‘votes’ and ‘talk.’ The Condorcet Jury Theorem is appealed to as a justification in terms votes, and the Hong-Page “Diversity Trumps Ability” result is appealed to as a justification in terms of deliberation. Both of these, however, are most plausibly construed as models of direct democracy, with full and direct participation across the population. In this paper, we explore how these results (...) hold up if we vary the model so as to reflect the more familiar democratic structure of a representative hierarchy. We first recount extant analytic work that shows that representation inevitably weakens the voting results of the Condorcet Jury Theorem, but we question the ability of that result to shine light on real representative systems. We then show that, when we move from votes to talk, as modeled in Hong-Page, representation holds its own and even has a slight edge. (shrink)

How children seek knowledge and evaluate claims may depend on their understanding of the source of knowledge. What shifts in their understandings about why scientists might disagree and how claims about the state of the world are justified? Until about the age of 41/2, knowledge is seen as self-evident. Children believe that knowledge of reality comes directly through our senses and what others tell us. They appeal to these external sources in order to know. The attainment of Theory of Mind (...) (ToM) at this age is commonly seen as the significant shift in development in understanding disagreements in knowledge claims. Children attaining ToM understand that someone exposed to incorrect or incomplete information might have false beliefs. Disagreement, then, is still attributed to objective sources of knowledge. The current study examines the later developing Interpretive Theory of Mind (iToM) as the basis for children’s understanding of how people with access to the same information might disagree and what this means for how to provide justification for a knowledge claim. Fourteen 2nd graders with the most iToM responses to four tasks and 14 with the fewest iToM responses were selected from a larger sample of 91. In analyses of interviews about a story in which two experts make different claims about a scientific phenomenon, those in the high iToM group noted subjective perspective and processes as the source of disagreement and suggested the need for investigation as the means to knowing. In contrast, those in the low iToM group mostly could not explain the source of disagreement and held that knowledge is acquired from external sources. A comparison of the interviews regarding the science story 2 years later allows for a qualitative description of the development. Those in the low iToM group showed more general recognition of subjective and constructive processes in knowing whereas those in the high iToM group identified interpretive processes and the relativity of perspectives with implications for how observations were conducted and interpreted. Only those in the high iToM group referred to the importance of evidence as a basis for knowledge claims at either point in the study. (shrink)

Understanding the dynamics of information is crucial to many areas of research, both inside and outside of philosophy. Using computer simulations of three kinds of information, germs, genes, and memes, we show that the mechanism of information transfer often swamps network structure in terms of its effects on both the dynamics and the fitness of the information. This insight has both obvious and subtle implications for a number of questions in philosophy, including questions about the nature of information, whether there (...) is genetic information, and how to arrange scientific communities.

We present ethical reasons that the court should grant the Nonhuman Rights Project’s (NhRP) request for habeas corpus relief for Happy, an elephant. Happy has a basic interest in not being confined, an interest that should be legally protected just as the human interest in not being confined is legally protected. Since the decision in The Nonhuman Rights Project, Inc. v Breheny failed to weigh Happy’s interests properly, we ask this body to correct the error.

Should the law recognize an elephant’s right to be released from solitary confinement? The New York State Court of Appeals—the highest court in the State of New York—will consider this question on May 18. At issue is an Asian elephant named Happy. But happy she is not. Every human being has a right to bodily liberty because they have strong interests that this right protects. Since Happy has the same strong interests, the Court should recognize Happy’s right to be freed (...) from solitary confinement. (shrink)

This article aims to describe the last 10 years of the collaborative scientific endeavors on polarization in particular and collective problem-solving in general by our multidisciplinary research team. We describe the team’s disciplinary composition—social psychology, political science, social philosophy/epistemology, and complex systems science— highlighting the shared and unique skill sets of our group members and how each discipline contributes to studying polarization and collective problem-solving. With an eye to the literature on team dynamics, we describe team logistics and processes that (...) we believe make our multidisciplinary team persistent and productive. We emphasize challenges and difficulties caused by disciplinary differences in terms of terminology, units/levels of analysis, methodology, and theoretical assumptions. We then explain how work disambiguating the concepts of polarization and developing an integrative theoretical and methodological framework with complex systems perspectives has helped us overcome these challenges. We summarize the major findings that our research has produced over the past decade, and describe our current research and future directions. Last, we discuss lessons we have learned, including difficulties in a “three models” project and how we addressed them, with suggestions for effective multidisciplinary team research. (shrink)

In this paper we make a simple theoretical point using a practical issue as an example. The simple theoretical point is that robustness is not 'all or nothing': in asking whether a system is robust one has to ask 'robust with respect to what property?' and 'robust over what set of changes in the system?' The practical issue used to illustrate the point is an examination of degrees of linkage between sub-networks and a pointed contrast in robustness and fragility between (...) the dynamics of (1) contact infection and (2) information transfer or belief change. Time to infection across linked sub-networks, it turns out, is fairly robust with regard to the degree of linkage between them. Time to infection is fragile and sensitive, however, with regard to the type of sub-network involved: total, ring, small world, random, or scale-free. Aspects of robustness and fragility are reversed where it is belief updating with reinforcement rather than infection that is at issue. In information dynamics, the pattern of time to consensus is robust across changes in network type but remarkably fragile with respect to degree of linkage between sub-networks. These results have important implications for public health interventions in realistic social networks, particularly with an eye to ethnic and socio-economic sub-communities, and in social networks with sub-communities changing in structure or linkage. (shrink)

Beyond belief change and meme adoption, both genetics and infection have been spoken of in terms of information transfer. What we examine here, concentrating on the specific case of transfer between sub-networks, are the differences in network dynamics in these cases: the different network dynamics of germs, genes, and memes. Germs and memes, it turns out, exhibit a very different dynamics across networks. For infection, measured in terms of time to total infection, it is network type rather than degree of (...) linkage between sub-networks that is of primary importance. For belief transfer, measured in terms of time to consensus, it is degree of linkage rather than network type that is crucial. Genes model each of these other dynamics in part, but match neither in full. For genetics, like belief transfer and unlike infection, network type makes little difference. Like infection and unlike belief, on the other hand, the dynamics of genetic information transfer within single and between linked networks are much the same. In ways both surprising and intriguing, transfer of genetic information seems to be robust across network differences crucial for the other two. (shrink)

In a series of formal studies and less formal applications, Hong and Page offer a ‘diversity trumps ability’ result on the basis of a computational experiment accompanied by a mathematical theorem as explanatory background (Hong & Page 2004, 2009; Page 2007, 2011). “[W]e find that a random collection of agents drawn from a large set of limited-ability agents typically outperforms a collection of the very best agents from that same set” (2004, p. 16386). The result has been extremely influential as (...) an epistemic justification for diversity policy initiatives. Here we show that the ‘diversity trumps ability’ result is tied to the particular random landscape used in Hong and Page’s simulation. We argue against interpreting results on that random landscape in terms of ‘ability’ or ‘expertise.’ These concepts are better modeled on smother and more realistic landscapes, but keeping other parameters the same those are landscapes on which it is groups of the best performing that do better. Smoother landscapes seem to vindicate both the concept and the value of expertise. Change in other parameters, however, also vindicates diversity. With an increase in the pool of available heuristics, diverse groups again do better. Group dynamics makes a difference as well; simultaneous ‘tournament’ deliberation in a group in place of the ‘relay’ deliberation in Hong and Page’s original model further emphasizes an advantage for diversity. ‘Tournament’ 2 dynamics particularly shows the advantage of mixed groups that include both experts and non-experts. As a whole, our modeling results suggest that relative to problem characteristics and conceptual resources, the wisdom of crowds and the wisdom of the few each have a place. We regard ours as a step toward attempting to calibrate their relative virtues in different modelled contexts of intellectual exploration. (shrink)

A first take, matured in later work, in modeling belief polarization.

Beyond reasonable doubt, the influence of Western culture and civilizations has enervated traditional African family systems, and their functions as providers of social welfare. Hitherto, traditional African family and clan by extension served as the plausible medium by which Africans proffered solutions to those social, economic and other existential problems found within their communities. However, measuring and evaluating the successes of the various social welfare programs organized by the family and clan was a difficult task to achieve. It seems the (...) services rendered merely controlled the social problems but did not improve the standard of living of the victims. This paper seeks to critically analyse the traditional African family system and its role as a provider of social welfare and argues that it can complement the Western models towards holistic social integration. Thus this work adopts the theory of change as a tool for understanding how Western models of social welfare should be integrated with traditional African approaches to care for the ‘weak’ in the society. Advocating for a paradigm shift from the modern models of providing social welfare to the traditional African family and clan model is consequent upon the claim that the latter is more embracing in approach.

This study used a structural equation modelling approach to assess the association between employee work- life policies, psychological empowerment, and academic staff job commitment in universities in Cross River State, Nigeria. Three null hypotheses were formulated to guide the study following a descriptive survey research design. Multistage sampling procedure was adopted in the selection of 315 academic staff from two universities in the study area. “Work-Life Policies, Psychological Empowerment and Job Commitment Questionnaire (WPPEJCQ)” was used as the instrument for data (...) collection. The construct validity of the instrument was ascertained through an Exploratory Factor Analysis (EFA) using the Principal Component Analysis (PCA). The Kaiser-Meyer-Ohlin of .894 and the Bartlett coefficient of 7795.820 were obtained. Several fit indices of Confirmatory Factor Analysis were used to accept the model such as RMSEA=.031, TLI=.969, CFI=.971 and many others. The null hypotheses were all tested using Path analysis. Findings revealed, among others, that there is a significant effect of work-life policies on the affective (β=.774,t=21.636,p<.05), continuance (β=.450,t=8.932,p<.05), and normative (β=490,t=9.967,p<.05) dimensions of academic staff commitment; furthermore, psychological empowerment has a significant effect on the affective (β=.795,t=23.199,p<.05), continuance (β=.501,t=10.261,p<.05) and normative (β = .520, t = 10.795, p< .05) dimensions of staff commitment; and there is a significant composite effect of work-life policies and psychological empowerment on the affective, continuance, and normative commitment levels of academic staff in universities. Based on these findings, conclusions and recommendations were made. (shrink)

We present evidence from a pre-registered experiment indicating that a philosophical argument––a type of rational appeal––can persuade people to make charitable donations. The rational appeal we used follows Singer’s well-known “shallow pond” argument (1972), while incorporating an evolutionary debunking argument (Paxton, Ungar, & Greene 2012) against favoring nearby victims over distant ones. The effectiveness of this rational appeal did not differ significantly from that of a well-tested emotional appeal involving an image of a single child in need (Small, Loewenstein, (...) and Slovic 2007). This is a surprising result, given evidence that emotions are the primary drivers of moral action, a view that has been very influential in the work of development organizations. We did not find support for our pre-registered hypothesis that combining our rational and emotional appeals would have a significantly stronger effect than either appeal in isolation. However, our finding that both kinds of appeal can increase charitable donations is cause for optimism, especially concerning the potential efficacy of well-designed rational appeals. We consider the significance of these findings for moral psychology, ethics, and the work of organizations aiming to alleviate severe poverty. (shrink)

Background: Previous studies assessing students’ learning outcomes and identifying contributing factors have often dwelt on the cognitive domain. Furthermore, school evaluation decisions are often made using scores from cognitive-based tests to rank students. This practice often skews evaluation results, given that education aims to improve the three learning domains. This study addresses this gap by assessing the contributions of four students’ input to their cognitive, affective and psychomotor skills (CAPs). Methods: A cross-section of senior secondary class II students (n = (...) 870), sampled through the multistage procedure, participated in a physical survey. Students’ Inputs Questionnaire (STIQ) and Learning Outcomes Questionnaire (LOQ) were used for data collection. Based on data obtained from a pilot sample (n = 412), principal axis factoring (PAF) was performed to assess the internal structure of the instruments following an oblique rotation. The KMO value of sampling adequacy were 0.88 and 0.94, while the Bartlett’s test of sphericity were significant χ2 (253) = 5,010; p < 0.001 and χ2 (105) = 3693.38, p < 0.001 for the STIQ and LOQ, respectively. Confirmatory factor analysis was used to assess the models’ acceptability based on the maximum likelihood estimation technique. The main study used hierarchical linear regression for data analysis. Results: Findings indicated that innate ability, health, motivation and social capital relatively and cumulatively predicted students’ overall, cognitive, affective and psychomotor learning outcomes. The proportion of variance explained by the predictors increased at different levels of the models with the addition of new variables. Students’ social capital reduced the effect of students’ innate ability regardless of their motivation and health status. Conclusion/implication: This study has provided evidence that the four students’ inputs are crucial predictors of their learning outcomes in the three domains. This result is helpful for school management to provide services aimed at improving the school climate for students’ motivation and social capital. The result can provide policymakers with a proper understanding of the constituents of learning outcomes and how policies can be aligned to secure quality student inputs for maximum productivity in education.

Previous research has interlinked alcohol consumption (AC), mental stress (MS), psychotic experiences (PE), and academic performance (AP) of students and psychological behavior of the general population. The current study seems to be the first to consider the joint and partial mediation effects of MS and PE in linking AC to graduates’ job performance in specific areas such as teamwork (TW), communication competence (CC), customer service (CS), and job functions (JF). A virtual cross-section of 3,862 graduates with self-reported cases of having (...) taken alcohol in the past participated in the study. These participants responded to an electronic questionnaire that was mailed to them. The instrument used for data collection had acceptable psychometric properties. The study used the partial least squares structural equation modeling (PLS-SEM) to achieve its objectives. The inner and outer models were all evaluated for quality and goodness of fit. Results showed a significant negative effect of AC and MS on graduates’ job performance in terms of TW, CC, CS, and JF, respectively. AC had a significant positive effect on MS and PE. MS had a significant positive effect on PE. A significant joint mediation effect of MS and PE was found in linking AC to graduates’ TW, CC, and CS, excluding JF. MS partially mediated AC’s paths to all the graduates’ job performance indicators. PE was only a significant partial mediator of the connection between AC to JF, but not TW, CC, and CS. This study’s result can help improve graduates’ work effectiveness and has revealed some negative predictors. Therefore, it is recommended that graduates avoid alcohol or only consume mild quantities of it to enable them to discharge services effectively at the workplace. (shrink)

Background: The attitudes of many undergraduates towards practicum exercise is declining in each passing year, affecting the quality of educational leaders produced from higher education. Studies in the past, have documented that there is no significant difference in the attitudes of students with or without practicum experience towards academic activities in higher education. Little or nothing seems to be known at the moment regarding the reasons why there is an indifference in the attitudes of students after completing a practicum course. (...) In response to this gap, we designed this study to assess principals' leadership variables as the presumed cause of undergraduates' declining attitudes towards practicum exercise in secondary schools. -/- Methods: A census study was carried out in Cross River State, where the entire 667 secondary school administrators (271 principals and 396 vice principals) were studied. “Principals’ Leadership Variables and Undergraduates’ Attitudes Towards Practicum Exercise Questionnaire” (PLVUATPEQ), designed by the researchers, was used in data collection. Data collected were analysed using simple linear regression analysis. Results: We find amongst others, that principals’ leadership styles, communication patterns, decision-making and supervisory approaches significantly predict undergraduates' attitudes towards practicum exercise relatively. Each of these independent variables accounts differently for the variance in the dependent variable based on their unique coefficient of determination. -/- Conclusion: It was concluded generally, that principals’ leadership variables significantly predict undergraduates’ attitudes towards practicum exercise. The attitudes of undergraduates towards practicum exercise increases as the leadership styles, communication patterns, decision-making skills, and supervisory approaches of principals improve. The implications of this study are discussed for policy and educational reforms. (shrink)

We argue on consequentialist grounds for the transfer of Sandai, an orangutan, to an orangutan sanctuary. First, we show that satisfying his interest in being transferred brings far greater value than the value achieved by keeping him confined. Second, we show that he has the capacities sufficient for personhood. Third, we show that all persons have a right to relative liberty insofar as they have interests they can exercise only under conditions of relative liberty. Fourth, we show that individuals need (...) not be able to assume social obligations and duties in order to be rights holders. -/- Our argument reflects commitments, as we say, to consequentialist reasoning about moral problems. However, we note that influential representatives of the other dominant ethical traditions—the deontological and Aristotelian traditions—reach our conclusion, too. It makes no difference, in this instance, which ethical theory one adopts. Under all of them, Sandai is a person with an interest in relative liberty entitled to habeas corpus protection. (shrink)

Public health care interventions—regarding vaccination, obesity, and HIV, for example—standardly take the form of information dissemination across a community. But information networks can vary importantly between different ethnic communities, as can levels of trust in information from different sources. We use data from the Greater Pittsburgh Random Household Health Survey to construct models of information networks for White and Black communities--models which reflect the degree of information contact between individuals, with degrees of trust in information from various sources correlated with (...) positions in that social network. With simple assumptions regarding belief change and social reinforcement, we use those modeled networks to build dynamic agent-based models of how information can be expected to flow and how beliefs can be expected to change across each community. With contrasting information from governmental and religious sources, the results show importantly different dynamic patterns of belief polarization within the two communities. (shrink)

This paper presents a passage from Peter Singer on the pond analogy and comments on its content and use in the classroom, especially with respect to the development of the learners' argumentative skills.

Peter Singer’s famous and influential article is criticised in three main ways that can be considered libertarian, although many non-libertarians could also accept them: 1) the relevant moral principle is more plausibly about upholding an implicit contract rather than globalising a moral intuition that had local evolutionary origins; 2) its principle of the immorality of not stopping bad things is paradoxical, as it overlooks the converse aspect that would be the positive morality of not starting bad things and also (...) thereby conceptually eliminates innocence; and 3) free markets—especially international free trade—have been cogently explained to be the real solution to the global “major evils” of “poverty” and “pollution”, while “overpopulation” does not exist in free-market frameworks; hence charity is a relatively minor alleviant to the problem of insufficiently free markets. There are also various subsidiary arguments throughout. (shrink)
