Social relationships are intricately tied to health and well-being and people are motivated to form and maintain interpersonal bonds. While it is clear that social relationships can be highly rewarding, it is equally clear that social relationships or the lack thereof can be the source of much distress. In this article a conceptualization of social motivation that reflects the basic necessity for people to simultaneously manage approaching the incentives and avoiding the threats in social relationships is presented. We then review (...) evidence that the strength of approach and avoidance social motives and goals is strongly linked to social outcomes through several behavioral, cognitive, and affective processes.

In this paper I examine the intracultural variability of parental and alloparental caregiving among the Aka foragers of the Central African Republic. It has been suggested that maternal kin offer higher frequencies of allocare than paternal kin and that maternal investment in infants will decrease when alloparental assistance is provided. Behavioral observations were conducted on 15 eight- to twelve-monthold infants. The practice of brideservice and the flexibility of Aka residence patterns offered a means to test the effect of maternal residence (...) on parental and alloparental investment. There was significant variation in the frequency of investment and who supplied care to infants depending on whether mothers resided with their kin or their husbands’ kin. However, in spite of the variation in allocare, when all categories of caregivers were examined collectively, infants received similar overall levels of care. (shrink)

This paper examines maternal trade-offs between subsistence/economic activities and caregiving, and it explores the effect of allomaternal investment on maternal time allocation and child care. I examine how nonmaternal investment in two multiple caregiving populations may offset possible risk factors associated with reductions in maternal caregiving. Behavioral observations were conducted on 8- to 12-month-old infants and their caregivers among the Aka tropical forest foragers and Ngandu farmers of Central Africa. Analysis demonstrates that mothers face trade-offs between subsistence/economic activities and infant (...) care. Infants receive less investment when their mothers engage in subsistence/economic activities, indicating a potential risk to those infants. However, results indicate that allomothers target their assistance during times when mothers are engaged in work activities, partially offsetting potential risks associated with the maternal trade-off. The effects of intercultural variability on maternal time allocation and allomaternal investment are also explored as a means of examining the potential impact of their behaviors on infant care.

Several studies have suggested a matrilateral bias in allomaternal (non-maternal) infant and child caregiving. The bias has been associated with the allomother’s certainty of genetic relatedness, where allomothers with high certainty of genetic relatedness will invest more in children because of potential fitness benefits. Using quantitative behavioral observations collected on Ngandu 8- to 12-month-old infants from the Central African Republic, I examine who is caring for infants and test whether certainty of genetic relatedness may influence investment by allomothers. Results indicate (...) a matrilateral bias in caregiving by extended kin members, but this does not affect the total level of care infants receive when fathers and siblings are included in the analysis. These results replicate a previous study done among an adjacent foraging population and emphasize the importance of examining children’s complete social environments when addressing caregiving and child development.

Benenson et al. amass impressive evidence of robust sex differences as support for expanding “staying alive” theory. We argue for a broader and more domain-specific conceptualization focusing on life history tradeoffs between survival and mating success. Using three examples – women's disgust, fear of rape, and cultivation of bodyguards – we illustrate these tradeoffs and suggest a broader theoretical framework.

Although higher education understands the need to develop critical thinkers, it has not lived up to the task consistently. Students are graduating deficient in these skills, unprepared to think critically once in the workforce. Limited development of cognitive processing skills leads to less effective leaders. Various definitions of critical thinking are examined to develop a general construct to guide the discussion as critical thinking is linked to constructivism, leadership, and education. Most pedagogy is content-based built on deep knowledge. Successful critical (...) thinking pedagogy is moving away from this paradigm, teaching students to think complexly. Some of the challenges faced by higher education moving to a critical thinking curricula are discussed, and recommendations are offered for improving outcomes. (shrink)

We study the effects of homeschool background and time use on academic performance among students at Patrick Henry College, a private religious institution with a 63-credit core classical liberal arts curriculum. Using ordinary least squares regression analysis, we examine four research questions: Does time use influence academic performance? Do homeschooled students perform differently than traditionally schooled students? Does parental education moderate the impact of homeschooling on academic performance? Does homeschooling moderate the impact of ACT scores on academic performance?

Harms and risks to groups and third-parties can be significant in the context of research, particularly in data-centric studies involving genomic, artificial intelligence, and/or machine learning technologies. This article explores whether and how United States federal regulations should be adapted to better align with current ethical thinking and protect group interests. Three aspects of the Common Rule deserve attention and reconsideration with respect to group interests: institutional review board (IRB) assessment of the risks/benefits of research; disclosure requirements in the informed (...) consent process; and criteria for waivers of informed consent. In accordance with respect for persons and communities, investigators and IRBs should systematically consider potential group harm when designing and reviewing protocols, respectively. Research participants should be informed about any potential group harm in the consent process. We call for additional public discussion, empirical research, and normative analysis on these issues to determine the right regulatory and policy path forward. (shrink)

ABSTRACTDespite interest in exercise as a treatment for anxiety disorders the mechanism behind the anxiolytic effects of exercise is unclear. Two observations motivate the present work. First, engagement of attention control during increased working memory load can decrease anxiety. Second, exercise can improve attention control. Therefore, exercise could boost the anxiolytic effects of increased WM load via its strengthening of attention control. Anxiety was induced by threat of shock and was quantified with anxiety-potentiated startle. Thirty-five healthy volunteers participated in two (...) types of activity, exercise and control-activity. After each activity, participants completed a WM task at low- and high-load during safe and threat. Results were not consistent with the hypothesis: exercise vs. control-activity increased APS in high-load. However, this incre... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Bonhoeffer’s Black Jesus: Harlem Renaissance Theology and an Ethic of Resistance by Reggie L. WilliamsCourtney H. DavisBonhoeffer’s Black Jesus: Harlem Renaissance Theology and an Ethic of Resistance Reggie L. Williams waco, tx: baylor university press, 2014. 196 pp. $39.95.In a year when nine people were killed in a historic black church and a litany of African American lives have been extinguished by police brutality, to say this book (...) about Dietrich Bonhoeffer and racialized interpretations of Jesus is timely is an understatement.Bonhoeffer was in search of a meaningful Christian theology through an authentic encounter with Jesus. Reggie Williams argues that Bonhoeffer, while [End Page 205] communing with people of color in 1930 Harlem at the height of its literary movement, found that meaning in the “black Christ” tradition otherwise unfamiliar to the young scholar. Bonhoeffer carried the identity of the black Christ to Germany, where he actively resisted Nazi atrocities and was executed in 1945. How is it that his ethic of resistance could be so singular, given that he was formed in much the same way as his “fundamentally oblivious” German peers (2)? Williams credits the difference to Harlem, where Bonhoeffer was schooled in hermeneutics and empathy; he further contends that Bonhoeffer’s practical experience in New York as well as the South and Cuba informed and motivated his attempts to actively eradicate the “lethal assumptions” of his peers in the German academy about God and humanity (3).On the undeniable influence of a hermeneutic, Williams states that a community of believers must have one; not only that, its hermeneutic must be connected to justice that extends concern beyond the confines of “self and kind” (3). Here Williams introduces the concept of empathy, which he describes as an ability to enter into the context of another’s suffering. Quite unintentionally, he informs the Rachel Dolezal controversy in noting that one does so without “losing grasp of one’s own separate identity” (3). Williams posits that Bonhoeffer must have experienced a “healthy and appropriate” empathy evidenced by his transformation from a theology that sanctioned racism prior to Harlem, to a willingness to share vicariously in the daily toll of racism in the black community, to resistance of racism upon returning to Germany (4). Bonhoeffer was not hamstrung by his social identity; he did not let being a white German scholar impede his ability to enter into the black American community and learn from it, “as though he had never been an outsider at all” (78).Williams argues that Bonhoeffer’s German peers did not possess such empathy because they had not shared in his Harlem experience. But there were in fact others in Germany who did not allow German nationalism to supersede Christ-centered resistance, even without the benefit of such an encounter. Although Williams does not address this fact in his argument, the historical documentation assembled in this book makes it plain that Harlem, the black literary movement, and Adam Clayton Powell Sr.’s ecclesiology did indeed have a profound effect on Bonhoeffer and his radical ethic of resistance.In addition to the exploration of Bonhoeffer’s time in Harlem, this book raises important considerations about scholarship and pedagogy that would benefit a broad audience. Williams, using Bonhoeffer’s own words, emphasizes that his early theology had been a demonstration of intellect rather than an expression of faith. Although he had written two dissertations, he was “not yet a Christian” when he set off for New York (109). When he returned, he lamented the German academy’s “guardians of purity” in Bonn who policed the borders of tradition—what was and was not taught in the classroom or preached on [End Page 206] Sunday (111). Has the academy continued this tradition of policing, and what is the rationale for the discipline of theology: intellectual religion or active faith? Williams makes the answers clear.Courtney H.

The inclusion of stakeholders and knowledge systems is increasingly valued in research to address complex socio-ecological challenges around the world. Often these projects take place in cross-cultural setting where external researchers risk perpetuating historically extractive research models that not only harm local communities but damage the validity of research projects. Responsible community engagement is increasingly recognized as a practice that can improve researcher-community relationships and research quality by incorporating principles of ethics, reciprocity, and power sharing. In partnership with local community (...) leaders, researchers from a U.S. university coded 76 research articles for indicators of responsible community engagement conducted in the Samburu, Kenya community since 2000. Findings from this study suggest that most of the research in Samburu has followed extractive models. Of the 76 articles reviewed many failed to acknowledge ethical protocols, did not address relevance of the study to the local community, and did not report any indication of outreach or community change as a result of the research. While a portion of articles showed evidence of community involvement in the studies, the involvement was primarily limited to secondary roles with little to no shared decision-making power over the research process. We discuss methodological considerations for future research and steps that must be taken in order to shift the norm and practice of academic research in sites such as Samburu, Kenya. (shrink)

Robert R. Reilly’s America on Trial: A Defense of the Founding argues that the intellectual roots of the founders’ political theory are found in the Christian understanding of man, society and the world, and in the tradition of natural law thinking that emerged under its aegis. The American founding, he concludes, must be understood as an attempted “re-establishment” of “the principles and practices” of medieval constitutionalism. While finding the broad outlines of Reilly’s argument persuasive, the author worries that Reilly does (...) not adequately take into account the eclectic character of the founders’ thought, the influence of the Enlightenment and Reformation on it, and the long-term implications of the latter influences for the historical trajectory of public order they created. The contrast between Reilly’s understanding of the founding and John Courtney Murray’s more nuanced account, the article argues, underscores both the strengths and weaknesses of this book. While both Reilly and Murray would agree that the founding was “good,” Murray, unlike Reilly, recognizes that “the seeds of dissolution” were present from the beginning and worries whether it is ultimately “good enough” to sustain the American experiment in self-government and ordered liberty.

In lieu of an abstract, here is a brief excerpt of the content:Beyond Ratzinger's Republic:Communio's Postliberal TurnSam Zeno Conedera S.J. and Vincent L. Strand S.J.Is the political future of the West a postliberal one? For the past decade, numerous prominent thinkers in America and Europe have been debating this question. Matters that not long ago were merely of historical interest, such as Pope Gelasius I's understanding of the relation between sacral authority and royal power, Thomas Aquinas's thought on monarchy and (...) Robert Bellarmine's theory of the pope's indirect authority in temporal matters are now increasingly studied for their potential answers to contemporary political questions. This development, which would have been nearly unimaginable just a decade earlier, unsurprisingly has been led by Catholics. We say "unsurprisingly" in view of the long pre-modern tradition of Catholic political thought, as well as the Church's long struggle against liberalism during the nineteenth and early twentieth centuries. Some of the current postliberal writers explicitly connect themselves to both of these aspects by using the term "integralist" to describe their position.1 [End Page 889]This "new integralism" represents a radical departure from the mainstream of Catholic political discourse of the last half century, which has largely sought rapprochement with Western liberalism. A group of writers, led by John Courtney Murray, George Weigel, Michael Novak, and Robert George, have held that the American constitutional order is rooted in the natural law tradition, and therefore is basically friendly to Catholic political thought. The Church's role in American life, they say, is upholding the natural law as a public moral philosophy, while embracing the non-establishment clause of the First Amendment as a matter of principle, in accordance with the teachings of the Second Vatican Council. This "Whig Thomism," which for decades represented the predominant outlook of conservative American Catholics, must now face the challenge of a different sort of Thomism represented by the integralists.2While the engagement between Whig Thomists and integralists has received most of the attention from scholars and journalists alike, another postliberal option has emerged in recent years. Its source is a group of Catholic thinkers associated with the Communio theological movement. Their political vision, which has no single name or label, has a complex and subtle relationship with the thought of earlier Communio writers, most of whom shared the Whig Thomist desire for reconciliation with Western liberalism. [End Page 890] The appearance of a Communio postliberalism therefore represents a significant development within this intellectual tradition. The most important representative of the earlier Communio perspective on political questions is Joseph Ratzinger / Pope Benedict XVI, who has recently been lauded as the "most important Catholic thinker of the twentieth century" on matters at the intersection of theology and politics.3In an article titled "Ratzinger's Republic" that appeared in these pages in 2020, we identified a significant tension in his thought about the Church's contribution to political life.4 Exploring Ratzinger's writings on natural law, we demonstrated that two currents are present. In accord with his fundamental theological commitments about nature and grace and about faith and reason, Ratzinger often questioned the effectiveness of arguments from natural law. He claimed that, since reason is historically conditioned, and therefore in the current order marked by sin, reason needs grace and faith to function properly. Yet, on other occasions, Ratzinger strongly endorsed arguments from natural law, highlighting its role as the foundation of a just democratic political order. We traced this ambivalence about natural law back to a dilemma at the heart of Ratzinger's political thought. On the one hand, in accord with his thinking about the relations of nature and grace and faith and reason, Ratzinger argued that the state needs the Church to supply moral values that the state cannot furnish on its own. On the other hand, he believed it belongs to the very nature of the Church to be separate from the state, and he endorsed nonconfessional, religiously pluralistic states.5 In light of these two commitments, Ratzinger argued that the contribution Christians are to make to the state is to supply moral values that were discerned under the influence of grace and divine revelation but...

L'influence de John Courtney Murray sur le développement - enchâssé dans Dignitatis Humanae- de l'enseignement de l'Église sur la liberté religieuse est largement connu. L'article montre que le caractère définitif de la contribution de Murray provient de deux perspectives centrales, l'une et l'autre issues des écrits de Bernard Lonergan. Tout d'abord, l'appropriation par Murray de la notion du «surgissement historique de la conscience» - que l'on ne conçoit pas simplement comme une attention aux événements et aux contextes historiques, mais (...) aussi à une «différenciation» propre de la conscience personnelle, sociale et ecclésiale - offre une clé de solution pour résoudre l'impasse créée par les vues conflictuelles, lors du Concile, sur la liberté religieuse. L'étude historique et théologique approfondie de Murray -avant, pendant et après le Concile - sur les thématiques qui touchent la question de la liberté religieuse est ensuite présentée comme une expression concrètement à l'oeuvre des «huit spécialités fonctionnelles» décrites par Méthode en théologie , lesquelles fondent la doctrine des Pères conciliaires pour lesquels un développement de l'enseignement social et moral de l'Église est nécessaire.

The purpose of this article is twofold. First, on the basis of a re-examination of the sources and with new arguments, it discusses the meaning of a verse-fragment quoted anonymously by Servius ad Aen. 4.638 (Enn. Ann. Dub. Fr. V Sk. = Inc. 31 blänsdorf, p. 434 courtney), and supports the attribution of this fragment to Ennius’ “Annales”. Second, it demonstrates that this attribution is not undermined by the presence, in the fragment, of a parenthetical phrase that is “in (...) apposition”, a stylistic feature which, though commonly believed to date back to Virgil’s time, may, in fact, be also attested in another Ennian fragment from the “Annales” (Enn. Ann. 22 Sk.). (shrink)

Charles-Louis de Secondat, baron de La Brède et de Montesquieu, mentions Niccolò Machiavelli by name in his extant works just a handful of times. That, however, he read him carefully and thoroughly time and again there can be no doubt, and it is also clear that he couches his argument both in his Considerations on the Causes of the Greatness of the Romans and their Decline and in his Spirit of Laws as an appropriation and critique of the work of (...) the predecessor whom he termed ‘this great man’. In this paper I explore the manner in which the Frenchman redeployed the arguments advanced by the Florentine for the purpose of refuting the latter's conclusions. ☆ In citing Machiavelli, I employ N.

When making decisions, humans can observe many kinds of information about others' activities, but their effects on performance are not well understood. We investigated social learning strategies using a simple problem-solving task in which participants search a complex space, and each can view and imitate others' solutions. Results showed that participants combined multiple sources of information to guide learning, including payoffs of peers' solutions, popularity of solution elements among peers, similarity of peers' solutions to their own, and relative payoffs from (...) individual exploration. Furthermore, performance was positively associated with imitation rates at both the individual and group levels. When peers' payoffs were hidden, popularity and similarity biases reversed, participants searched more broadly and randomly, and both quality and equity of exploration suffered. We conclude that when peers' solutions can be effectively compared, imitation does not simply permit scrounging, but it can also facilitate propagation of good solutions for further cumulative exploration.

Nel 2011 il National Theatre di Londra celebrava il trentesimo anniversario della produzione dell’ Oresteia (Agamennon, Choefori e Eumenides) con una grande mostra che raccontava il lungo processo di creazione di uno degli allestimenti più famosi del teatro inglese degli ultimi quarant’anni; si tratta dell’adattamento e della traduzione della Trilogia di Eschilo a opera del poeta e scrittore inglese Tony Harrison, con la regia di Peter Hall (direttore del Teatro Nazionale dal 1973 al 1988) e le scene e le maschere (...) di Jocelyn Herbert. Questa mostra curata da Cathy Courtney, arrivava sette anni dopo la grande esposizione dedicata alla scenografa inglese intitolata Jocelyn Herbert at the National (2004).Il presente saggio racconta il lungo percorso creativo che ha portato alla definizione, oltre che di un’originale traduzione, anche di un particolare allestimento scenico che prevedeva l’uso di maschere per i soli attori uomini, create dalla Herbert, una delle più famose stage designer britanniche. I materiali preparatori sono stati messi a disposizione online negli ultimi anni, grazie a un progetto di digitalizzazione del National Theatre in collaborazione con Google Culture Institute. Proprio alle maschere della Herbert e alle diverse proposte e trattamenti della maschera greca in chiave contemporanea è dedicato un contributo critico finale che le affianca comparativamente sia a quelle del mascheraio e studioso di teatro greco classico Ferdinando Falossi, sia alle maschere video digitali e fotografiche create rispettivamente da Teatrino Giullare e da Marzio Emilio Villa.
