Although the demarginalisation of youths is an international concern, South African youths are viewed by various scholars and policy documents as a particularly vulnerable and marginalised group. It becomes essential to understand what characterises their marginalisation in order to find innovative ways to work towards their demarginalisation. In this article we reflect on current faith-based concerns and compare this with the specific characteristics of the marginalisation of young people. In an effort to contribute to the development of a strategy towards (...) demarginalisation, we will explore the key features of the Circle of Courage in terms of the principles of belonging, mastery, independence and generosity. We will further propose the inclusion of Ubuntu principles in the practical application of the Circle of Courage for churches and faith-based organisations in demarginalising youth in the South African context.

Since literary historian Robert Bone published his seminal essay ‘Richard Wright and the Chicago Renaissance’ in 1986, scholars have created new cartographies of previously unexplored terrain in American cultural history. The earliest studies focused on literature, but more recently attention has turned to other disciplines, including visual arts. Recent publication of The Muse in Bronzeville: African American Creative Expression in Chicago, 1932–1950 (2011) by Robert Bone and Richard A. Courage promises to decisively broaden scholarly understandings of the scope and (...) significance of Chicago-centred cultural production during the Great Depression and post-war years. Of particular relevance to contemporary studies of new media art is the manner in which then-emergent ideas and practices – centring on racialized subject matter, elite and mass audiences, traditional and new mediums of expression, private vs public sponsorship, and passive vs active reception of art objects – converged to create new paradigms and possibilities for visual artists to reshape consciousness in a period of institutional collapse and change. Chicago’s New Negro artists of the 1930s and 1940s, like their counterparts in 1920s Harlem, sought to reframe perceptions of African American life, to re-present the black subject as something other than an object of contempt or amusement beneath the privileged gaze of the white viewer. Just as these artists sought to revise perceptions of racial reality, examination of the wide range of actual images they created and the mediums and styles they explored revises reductive notions about creative expression in this period, which often portray a mere subordination of art to propaganda and an embrace of representational aesthetics and simplistic narratives in a fruitless detour in the evolution from modernism to postmodernism. On the contrary, Andrew Hemingway notes the range of stylistic experiment and characterizes so-called ‘social art’ as ‘a hybrid and unstable mode [which] had to carry the imperative to be an art equal in formal achievement to both the great art of the past and the modern tradition … [and] to suggest a political orientation without becoming overt revolutionary propaganda’ (2002).New media theorist Oliver Grau observes thatIn many quarters, virtual reality is viewed as a totally new phenomenon… but it did not make its first appearance with the technical invention of computer-aided virtual realities. On the contrary, virtual reality forms part of the core of the relationship of humans to images… grounded in art traditions that have receivedscant attention up to now.(2004)In the midst of another period of change, of transformed and transforming ideas and practices in the arts, we have much to learn from the attempts of Chicago’s New (Media) Negro artists to create ‘art for the people’, to immerse broad audiences in such accessible media as mural painting, photography and graphic arts.

In Judgment and Agency, Ernest Sosa takes “reliabilist” virtue epistemology deep into “responsibilist” territory, arguing that “a true epistemology” will assign “responsibilist-cum-reliabilist intellectual virtue the main role in addressing concerns at the center of the tradition.” However, Sosa stops short of granting this status to familiar responsibilist virtues like open-mindedness, intellectual courage, and intellectual humility. He cites three reasons for doing so: responsibilist virtues involve excessive motivational demands; they are quasi-ethical; and they are best understood, not as constituting knowledge, (...) but rather as putting one “in a position” to know. I elaborate on and respond to each of these concerns. I argue that none of them provides Sosa with a good reason for excluding responsibilist virtues from occupying a central role in his reliabilist virtue epistemology. I conclude that Sosa owes virtue responsibilism an even wider embrace. (shrink)

Although very young children have unprecedented access to touchscreen devices, there is limited research on how successfully they operate these devices for play and learning. For infants and toddlers, whose cognitive, fine motor, and executive functions are immature, several basic questions are significant: Can they operate a tablet purposefully to achieve a goal? Can they acquire operating skills and learn new information from commercially available apps? Do individual differences in executive functioning predict success in using and learning from the apps? (...) Accordingly, 31 2-year-olds were compared with 29 3-year-olds using two commercially available apps with different task and skill requirements: a shape matching app performed across 3 days, and a storybook app with performance compared to that on a matched paper storybook. Children also completed the Minnesota Executive Functioning Scale. An adult provided minimal scaffolding throughout. The results showed: toddlers could provide simple goal-directed touch gestures and the manual interactions needed to operate the tablet after controlling for prior experience with shape matching, toddlers’ increased success and efficiency, made fewer errors, decreased completion times, and required less scaffolding across trials, they recognized more story content from the e-book and were less distracted than from the paper book, executive functioning contributed unique variance to the outcome measures on both apps, and 3-year-olds outperformed 2-year-olds on all measures. The results are discussed in terms of the potential of interactive devices to support toddlers’ learning. (shrink)

The focus of this study was to assess the mediating effect of green innovation, in the relationship between green human resources management (GHRM) and organizational competitiveness of manufacturing multinational enterprises (MNEs). The study further looked at the moderating effect of organizational learning in the relationship between GHRM on organizational competitiveness of manufacturing MNEs. The population comprises manufacturing MNEs in Ghana. Through purposive and simple random sampling techniques, 231 manufacturing MNEs were selected for the study. Data was analyzed using frequencies, percentages, (...) mean scores, and Structural Equation Modeling (SEM), using SPSS and SMART‐PLS (Partial Least Square) software. The study concludes that green innovation partially mediates the relationship between GHRM and organizational competitiveness. It was further concluded that organizational learning positively moderates the positive relationship between GHRM and organizational competitiveness. The study recommends that manufacturing MNEs should invest and improve the level of their organizational learning as it not only strengthens the effects of GHRM on organizational competitiveness, but it also directly improves competitiveness. Further, particular attention should also pay to green innovation, as it intervenes the relationship between GHRM and organizational competitiveness. (shrink)

In this article, we focus on two issues, namely, the nature and onset of very early personal memories, especially for traumatic events, and the role of stress in long-term retention. We begin by outlining a theory of early autobiographical memory, one whose unfolding is coincident with emergence of the cognitive self. It is argued that it is not until this self emerges that personal memories will remain viable over extended periods of time. We illustrate this with 25 cases of young (...) children′s long-term retention of early traumatic events involving emergency room treatment. On the basis of both qualitative and quantitative analyses, we conclude that very young children retain limited memories for events which they commonly express behaviorally, coherent autobiographical memories are not constructed until the child develops a cognitive sense of self , autobiographical memories for traumatic events are essentially no different from those for nontraumatic events, stress is only related to long-term retention inasmuch as it is one variable that serves to make an event unique, and like nontraumatic events, traumatic memories lose peripheral details during the retention interval and retain the central components of the event. These results are discussed both in terms of their implications for theories of early autobiographical memory as well as the ways in which we might differentiate implanted memories and authentic memories for traumatic events.

American leaders in four realms were studied to assess their views on the helpfulness to workers with family obligations of employers' policies and services. The realms were corporate management, labor unions, the pro-family movement, and the feminist movement. The data were analyzed by leadership realm and gender in relation to policies of two types: scheduling and work arrangements and services and benefits. Gender accounted for the respondents' views better than class or social movement did. Except for feminist men, the men (...) held similar views regardless of leadership realm. The pro-family women differed from the other women in failing to view most services and benefits as particularly helpful to employees. Union and corporate women's favorable views on services and benefits suggest that fundamental change in workplace supports for workers' family obligations could develop if more women became leaders in unions and corporations.

The current study sought to assess the mediating role of green market orientation dimensions in the relationship between social risk and new product performance among European Multinational Enterprises (EMNEs). We also assessed the moderating role of entrepreneurial orientation in the relationship between green market orientation and new product performance. The study was based on primary data gathered from 317 EMNEs in Ghana. After various validity and reliability checks, ordinary least squares (OLS) analysis was performed to estimate the various relationships hypothesized (...) in the study. The study finds that social risk has a negative effect on the success of EMNEs' new products. This negative effect is however nullified by the positive mediating effects of strategic green market orientation, tactical green market orientation and internal green market orientation. Entrepreneurial orientation also played a significant moderating effect in the relationship between green market orientation dimensions and EMNEs' new product performance. Based on this, theoretical and managerial contributions were made. (shrink)

Background:Moral courage is defined as courage to act according to one’s own ethical values and principles even at the risk of negative consequences for the individual. In a complex nursing practice, ethical considerations are integral. Moral courage is needed throughout nurses’ career.Aim:To analyse graduating nursing students’ moral courage and the factors associated with it in six European countries.Research design:A cross-sectional design, using a structured questionnaire, as part of a larger international ProCompNurse study. In the questionnaire, moral (...) courage was assessed with a single question (visual analogue scale 0–100), the questionnaire also covered several background variables.Participants and research context:The sample comprised graduating nursing students (n = 1796) from all participating countries. To get a comprehensive view about graduating nursing students’ moral courage, the views of nurse managers (n = 538) and patients (n = 1327) from the same units in which the graduating nursing students practised were also explored, with parallel questionnaires.Ethical considerations:Ethical approvals and research permissions were obtained according to national standards in every country and all participants gave their informed consent.Results:The mean of graduating nursing students’ self-assessed moral courage was 77.8 (standard deviation 17.0; on a 0–100 scale), with statistically significant differences between countries. Higher moral courage was associated with many factors, especially the level of professional competence. The managers assessed the graduating nursing students’ moral courage lower (66.5; standard deviation 18.4) and the patients slightly higher (80.6; standard deviation 19.4) than the graduating nursing students themselves.Discussion and conclusions:In all countries, the graduating nursing students’ moral courage was assessed as rather high, with differences between countries and populations. These differences and associations between moral courage and ethics education require further research. (shrink)

This interactive teaching workshop explored what it means to “teach from the heart.” It adopted the format of the wisdom circle to ask participants to share peak teaching experiences so that they could reflect on what their stories reveal about their inner selves as teachers. The hope was that, by learning how to speak with their “authentic” voices, participants could gain the insight and courage needed to better connect with their students as co-learners.

The Historia Novella is a key source for the succession dispute between King Stephen and the Empress Matilda which brought England to civil war in the twelfth century. William of Malmesbury was the doyen of the historians of his day. His account of the main events of the years 1126 to 1142, to some of which he was an eyewitness, is sympathetic to the empress's cause, but not uncritical of her. Edmund King offers a complete revision of K. R. Potter's (...) edition of 1955, retaining only the translation, which has been amended in places. Not only is this a new edition but it offers a new text, arguing that what have earlier been seen as William of Malmesbury's final revisions are not from his hand. Rather they seem to come from somewhere in the circle of Robert of Gloucester, the empress's half-brother, to whom the work is dedicated. In this way the work raises important questions concerning the transmission of medieval texts. (shrink)

The book aims at the logical and conceptual analysis of philosophical problems in logic, analysis of mind and knowledge. In presents several internal connections between logical, practical and ethical reasoning and getting individual and collective knowledge. The author connects conceptual analysis, some modal logical arguments and some Wittgensteinian motives in the analysis of vagueness, process logic, skepticism, practical reasoning and getting knowledge.

Safe-by-Design is an approach to engineering that aims to integrate the value of safety in the design and development of new technologies. It does so by integrating knowledge of potential dangers in the design process and developing methods to design undesirable effects out of the innovation. Recent discussions have highlighted several challenges in conceptualizing safety and integrating the value into the design process. Therefore, some have argued to design for the _responsibility_ for safety, instead of for safety itself. However, this (...) idea has not been developed further. In this article, we develop an approach to Safe-by-Design, grounded in care ethics, which builds on the idea of designing for responsibility and can deal with the complexity that is inherent to the conceptualization of safety. We describe five ways in which care ethics contributes to the conceptualization of Safe-by-Design: (1) It suggests the development of ‘circles of care’ in which stakeholders share the responsibility for safety; (2) it recognizes the importance of considering safety as something that is situated in the surroundings of a technology, instead of as a property of the technology itself; (3) it acknowledges that achieving safety is labour that requires an ongoing commitment; (4) it emphasizes that the way in which we relate to technology impacts its safety; and (5) it recognizes the role of emotions in assessing safety. All these elements combined lead to a broader understanding of safety and a philosophically more substantial and practically more appealing conceptualization of Safe-by-Design. (shrink)

A major philosophical mind in his day, William Paley wrote in a lucid style that made complex ideas more accessible to a wide readership. This work, first published in 1785, was based on the lectures he gave on moral philosophy at Christ's College, Cambridge. Cited in parliamentary debates and remaining on the syllabus at Cambridge into the twentieth century, it stands as one of the most influential texts to emerge from the Enlightenment period in Britain. An orthodox theologian, grounding his (...) utilitarian ethics in strong religious faith, Paley held notably progressive views on issues of toleration and the slave trade. His perspicuity prompted one contemporary to remark that the book 'presents a subject which has always been considered as harsh and difficult, in the most agreeable and intelligible form … we sit down to be informed of our duty, and are surprised to meet with amusement'.

In this article we will suggest that the traditional account of the freedom of expression needs revision. The emergence of Internet media has shown that the traditional ideal of a plurality of voices does not in itself lead to fruitful public spheres. Inspired by Foucault’s interpretation of the Greek concept parrhesia we suggest that the plurality of voices should be supplemented with an ideal of courageous truth-telling. We will furthermore argue that the notion of courage has two dimensions that (...) should be taken into account. On the one hand a Derridean reading of courage brings out a disruptive and aporetic feature of courage. On the other hand, courage also needs to be articulated through some kind of goal, which in a public setting calls for a deliberative dimension. We conclude by suggesting that public spheres with courageous truth-telling will facilitate societies in which strong voices and opinions are continuously challenged by less strong voices. (shrink)

Courage is dangerous. If it is defined in traditional ways, as a set of dispositions to overcome fear, to oppose obstacles, to perform difficult or dangerous actions, its claim to be a virtue is questionable. Unlike the virtue of justice, or a sense of proportion, traditional courage does not itself determine what is to be done, let alone assure that it is worth doing. If we retain the traditional conception of courage and its military connotations–overcoming and combat–we (...) should be suspicious of it. Instead of automatically classifying it as a virtue, attempting to develop and exercise it, we should become alert to its dangers. And yet and yet. There is an aspect of traditional courage that serves us: we require the capacities and traits that enable us to persist in acting well under stress, to endure hardships when following our judgments about what is best is difficult or dangerous. If courage is checked, redefined as the virtue that enables virtue–the various sets of dispositions, whatever they may be, that make us resolute in worthy, difficult action–then we need not fear the dangers of courage. We need rather to reform it by diversifying it, as a heterogeneous variety of traits that enable us to act well under stress, against the natural movements of self-protection. (shrink)

Much contemporary political philosophy claims to be Kant-inspired, but its aims and method differ from Kant's own. In his recent book, Force and Freedom, Arthur Ripstein advocates a more orthodox Kantian outlook, presenting it as superior to dominant (Kant-inspired) views. The most striking feature of this outlook is its attempt to ground the whole of political morality in one right: the right to freedom, understood as the right to be independent of others’ choices. Is Ripstein's Kantian project successful? In this (...) research note I argue that it is not. First, I suggest that Ripstein's notion of freedom is viciously circular. It is meant to ground all rights, but in fact it presupposes an account of those rights. Second, I show that—independently of its inability to ground a whole political morality—such a moralized understanding of freedom is normatively unappealing. (shrink)

The first poems about the Prophet Muḥammad appeared while he was alive. These first examples, which are panegyrics (madīḥ, i‛tiẕār, fakhr and ris̱ā), largely reflect the characteristics of the pre-Islamic qaṣīda poetry. Due to the developments in the following centuries, the number of poems about the Prophet increased. And thus, a separate literary genre was formed under the name al-madīḥ al-nabawī. Especially the fact that sufi leaning poets contributed to the literary richness in this field. Another factor is the beginning (...) of the tradition of writing mawlid poems in memory of the birth of the Prophet Muḥammad. The thirteenth century was an important period for poems praising the Prophet Muḥammad. Two important poets emerged in this century. One of them is Egyptian poet al-Būṣīrī and the other is Baghdad's famous poet, Yaḥyā al-Ṣarṣarī. Even after his death, Ṣarṣarî’s works with high literary value were read and memorized in the circles of science, literature and Sufism. Due to his competence in the field, al-Ṣarṣarī was known as the poet of the Prophet and Ḥassān b. Thābit of his time. However, it is understood that his poems, which lost their importance in literary circles over time, were not studied as much as they deserved in the modern period. In this article, his life and works are introduced and basic language and stylistic features of his poems are examined. Also, the image of the Prophet in his poems was determined within the framework of the political conditions of the period.Summary: In the field of madīh nabawī, which first appeared in the ‘Asr al-Sa’āda and has continued to the present day, especially two names stand out in the 7th/13th century, when famous poets such as Macduddīn al-Vitrī (d. 662/1264), Ibn al-Muraḥḥal (d. 699/1300) and Ṣafiyyuddīn al-Ḥillī (d. 749/1348) were also raised. One of them is the Egyptian poet al-Būṣīrī (d. 695/1296), who left his mark on the field of madīh nabawī with his many poems, especially Qaṣīda Burda, and the other is the Iraqi poet Yahya al-Ṣarṣarī (d. 656/1258), who was named Shā‘iru Rasūlillāh (The poet of the Prophet) and Ḥassānu Vaḳtihī (Ḥassān of that period) because of the quality of his poems in this field.al-Ṣarṣarī, was born in the village of al-Ṣarṣar, near Baghdad, spent most of his life in the shadow of Baghdad’s political instability and the social collapse that developed in parallel. He was killed in 656/1258 by the Mongolian forces that invaded Baghdad. al-Ṣarṣarī was extremely knowledgeable in fiqh, hadith, language, and ‘ilm al-qirāa. Our poet adopted the views of the Hanbalī law school. In addition, he turned to Sufism and became a murīd (disciple) of Ali ibn Idrīs al-Ya‘kūbī, a student of Abdalqadīr al-Gīlanī who was accepted as the founder of Qādiriyya. He was closely attached to the Sunnah of the Prophet and was fond of reading the Quran. He was chaste and patient and was content with what he had himself. All his works are poetic and they all concern the madīh nabawī or fiqh.Since his poems, almost all of which are about the praise of the Prophet, have a high literary value, they were read, memorized and narrated for a long time in the circles of science, literature and Sufism. In terms of its structure, his poems are based on the traditional forms of Arab qasīda. In the introductory sections of his poems, he often expresses his longing for Madina. The main subject in poems is usually the Prophet and his superior features. In the last part, he usually says salāt for the Prophet and seeks help from him. It can be said that he used simple language in his poems. The vocabulary reflects the characteristics of the urban life in which he lived. The source of inspiration for his poems are the Qur’an and especially the hadith of the Prophet. He uses the potential of literary arts as much as possible while conveying his feelings. But he does not allow the correct information to be lost due to these arts on a serious subject such as depicting the Prophet. We can see a lot of badī‘ (creative) art in some of his poems. But we can immediately understand that these arts do not spoil the beauty of his expression. The poet provides rhythm and harmony in his poetry with the meter and rhyme in accordance with the classical Arabic qasida rules. In addition, he strengthens the musicality in poetry with puns (jinās) and repetition.The influence of the instability of the region where al-Ṣarṣarī lived on his poems is obvious. According to him, the main reason for the terrible situation that Muslims were in was that they were away from the way of the Prophet. He thought that it would be possible to go back to the old peaceful days by following the way of the Prophet. Perhaps as a result of this opinion, he allocated his qasīda to the narration of the Prophet and his Companions. In his poems, he describes the Prophet with his names, superior qualities, physical and moral characteristics. He says that the sentences describing the Prophet are the ornament of poems and believes that praising him is a mean of salvation in the next world. He also hoped that the poems he said in order to achieve spiritual ascension would protect himself against the troubled events of the period.In his poems, especially on the occasion of mawlīd, al-Ṣarṣarī mentions the Prophet’s physical characteristics and likens his smiling face to a bright full moon, his brows to the letter nûn, his teeth to pearls. He describes the Prophet as a man with black eyes, broad shoulders, born with kohl-lined eyes, and who emanates a beautiful scent as a requirement of his creation. The poet, who also touches on the Prophet’s powerful address, states that his speech is more effective than Luqman’s wise words by virtue of his jawami‘ al-kalim (comprehensive speech) and faṣl al-khiṭab (clear speech), and that his soft address, which states nothing other than the truth, is a blessing from Allah. He additionally describes the Prophet’s plain words, easy to understand by all, as more valuable than jewels. al-Ṣarṣarī, who praises the Prophet in terms of morality with basic human virtues such as bashfulness, justice, modesty, and courage, emphasizes that he is, a paragon of patience, perseverance, kindness, and compassion through analogies such as, “his clothes are peace and perseverance”, his “cover is kindness and forgiveness”. In his world of imagery, the Prophet’s benevolence is so abundant like the rain that the clouds cannot compete with him. Also, he does not shame anybody for what he gives. He bestows the most valuable possessions like gold and camels. Even the respectable personalities of the tribe benefit from his grace. He is so generous that he is giving even when the clouds are stingy about giving rain during times of drought. He welcomes with a smile those who approach him with requests. The donations he makes privately are entirely satisfying.The image of prophethood in al-Ṣarṣarī’s poems, is centralized around the thought of nūr Muhammadī (prophetic light) and the miracles of the Prophet. He reminds that the Prophet never gave up despite the calamities he encountered and that he was supported with extraordinary events in various stages of his life since he was born, and reflects the understanding that the prophet is spiritually supporting the community with his nūr, and in the case the community follow his sunnah, overcoming the Mongolian attacks, which seems like a miracle, is possible. The mention of Qattāl (warrior), Māḥī (eliminator of disbelief), Ẓāhir, Ẓāfir, Manṣūr and Muẓaffar (victorious) among the Prophet’s names, especially those that evoke the superiority he gained in his fight against the disbelievers, giving greater prominence to his courage and valor among his virtues are also related to the political and social conditions of the period. The couplets about the Companions of the Prophet following the couplets that describe the Prophet’s valor, the emphasis of their aid to the Prophet, and the particular mention of their fighter spirit may be considered in the same context. Perhaps, in this way, the poet aims to boost the courage of the Muslims who are exposed to Mongolian attacks with respect to protecting their spiritual and holy values against the enemy. (shrink)

Metaphysicians of a certain stripe are almost unanimously of the view that grounding is necessarily irreflexive, asymmetric, transitive, and well-founded. They deny the possibility of circles of ground and, therewith, the possibility of species of metaphysical coherentism. But what's so bad about circles of ground? One problem for coherentism might be that it ushers in anti-foundationalism: grounding loops give rise to infinite regresses. And this is bad because infinite grounding regresses are vicious. This article argues that circles of ground do (...) not necessarily give rise to infinite regresses, and where they do, those regresses are not necessarily vicious. (shrink)

Roland Barthes’ entire career pursued a dream of being freed from the tyranny of ossified, institutionalized, rote language use, as articulated from his first massively influential work on ‘writing degree zero’ in 1953. The anaemic role of institutional rhetoric and its dusty formulations dulled the capacity for using language and thought otherwise. For Barthes, fragments played a privileged role in the escape from the tyranny of meaning imposed by doxa and received wisdom, sometimes called ‘literature’ and ‘rhetoric’. Barthes once referred (...) to almost all of his writing, and indeed theorizing, as ‘a circle of fragments’. The artist and theorist Victor Burgin has been profoundly influenced by Barthes’ writings and his attempts to escape the ideological constraints of language, institutions and images. His visual rhetorical practice now often takes the form of projection loops that are accessible by gallery attendees at any point in the loop. Their basic building block is also the fragment, and the loop constitutes another circle of fragments. His 2016 work Belledonne uses the time Barthes spent in the sanatorium for tuberculosis treatment as the basis for the piece, its computer-generated imagery and textual intertitles. This article examines Barthes’s writings on pre-Socratic rhetoric, as well as his self-reflexive engagement with his own theorizing, combined with Burgin’s reconsideration of moving image work in gallery or museum spaces as attempts to offer potentially liberatory strategies for eluding rote use and effects of language, image and thought.

We hypothesize that threat of dehydration provided selection pressure for the evolutionary emergence and persistence of the anterior communicating artery (ACoA – the inter‐arterial connection that completes the Circle of Willis) in early amniotes.The ACoA is a hemodynamically insignificant artery, but, as we argue in this paper, its privileged position outside the blood‐brain barrier gives it a crucial sensing function for the osmolarity of the blood against the background of the rest of the brain, which efficiently protects itself from (...) dehydration. Till now, the questions of why the ACoA evolved, and what its physiological function is, have remained unsatisfactorily answered. The traditional view—that the ACoA serves as a collateral source of vascularization in case of arterial stenosis—is anthropocentric, and not in accordance with principles of natural selection that apply more generally. Diseases underlying arterial stenosis are associated with aging and the human lifestyle, so this cannot explain why the ACoA formed hundreds of millions of years ago and persisted in amniotes to this day.The peculiar hemodynamic properties of the ACoA could be selected traits that allowed for more efficient forebrain detection of dehydration and complex behavioral responses to water loss, a major advantage in the survival of early amniotes. This hypothesis also explains insufficient hydration often seen in elderly humans. (shrink)

Hermeneutic studies of science locate a circle at the heart of scientific practice: scientists only gain knowledge of what they, in some sense, already know. This may seem to threaten the rational validity of science, but one can argue that this circle is a virtuous rather than a vicious one. A virtuous circle is one in which research conclusions are already present in the premises, but only in an indeterminate and underdeveloped way. In order to defend the (...) validity of science, the hermeneuticist must describe a method by which a vague and confused initial knowledge of nature gets transformed into a clear and determinate knowledge of nature. I consider three such methods. The first is regressus demonstrativa, favoured by the physicians of Padua during the fifteenth and sixteenth centuries. The second is mathēsis, introduced by Martin Heidegger in his discussion of seventeenth-century science. The third is Denkstil, a key concept in Ludwik Fleck’s history of syphilology. I conclude by listing three desiderata for a hermeneutic science studies: that it be anti-metaphysical, historical, and sociological. --- Reprinted in: Erich Otto Graf, Martin Schmid & Johannes Fehr (eds.), Fleck and the Hermeneutics of Science (Collegium Helveticum Heft 14) (Zürich, 2016), pp. 85-93.

Abstractabstract:This paper offers a new interpretation of courage in Plato's Republic. Despite the attention that this dialogue has received in the past, scholars have been disinclined to explore the metaphysics of the virtues. I argue that courage is, by its very nature, a δύναμις of the sort described in book 5. In particular, I argue that courage is the power over reason's correct practical deliberations about what one ought to do and that it accomplishes the preservation of (...) these deliberations in the face of appetitive threats. I then explore the implications this has for the moral psychology of the virtuous agent and the question of who can be genuinely courageous. (shrink)

Plato and the Virtue of Courage canvasses contemporary discussions of courage and offers a new and controversial account of Plato's treatment of the concept. Linda R. Rabieh examines Plato's two main thematic discussions of courage, in the Laches and the Republic, and discovers that the two dialogues together yield a coherent, unified treatment of courage that explores a variety of vexing questions: Can courage be separated from justice, so that one can act courageously while advancing (...) an unjust cause? Can courage be legitimately called a virtue? What role does wisdom play in courage? What role does courage play in wisdom? Based on Plato's presentation, Rabieh argues that a refined version of traditional heroic courage, notwithstanding certain excesses to which it is prone, is worth honoring and cultivating for several reasons. Chief among these is that, by facilitating the pursuit of wisdom, such courage can provide a crucial foundation for the courage most deserving of the name. (shrink)

Combining in-depth analysis with strikingly apt examples of the role that courage plays in the life of human beings, this major contribution to moral philosophy argues that courage is necessary to personal achievement as well as to the common good of a civic community. Bauhn insists that courage is necessary for reinforcing people's understanding of themselves as autonomous agents, which is in turn necessary for countering widespread feelings of alienation and depression. He defines courage as the (...) ability to confront fear, but crucially distinguishes a variety of fears that give rise to different types of courage. (shrink)

Cooperative learning processes have been rediscovered and are being used throughout the country on every level. The basic elements of cooperative goal structure are positive interdependence, individual accountability, face-to-face interaction, and cooperative skills. The teacher's role in structuring cooperative learning situations involves clearly specifying lesson objectives, placing students in productive learning groups and providing appropriate materials, clearly explaining the cooperative goal structure, monitoring students, and evaluating performance. For cooperative learning groups to be productive, students must be able to engage in (...) the needed collaborative skills. Cooperative skills and academic skills can be taught simultaneously. The implementation of cooperative learning needs to be coupled with the implementation of collaborative professional support groups among educators. Both the success of implementation efforts and the quality of life within most schools depend on teachers and other staff members cooperating with each other. Support for the program takes as careful structuring and monitoring as does cooperative learning. (JD). (shrink)

This article examines the values that underlie notions of sustainability and corporate social responsibility, and how those values influence perspectives on who and what is included in decision-making. The author argues that the epistemologies of economic considerations in industrial practices, and how they are framed by science and technology, make it unlikely that practices towards sustainability will successfully avert expanding global crises unless the circle of inclusion is expanded to include other-than-human life.

The question whether semantics is a normative discipline can be formulated as a question about the meaning of the word “means”. If I assert, “The word ‘gatto’ in Italian means cat,” what have I done? The naturalist about meaning claims that I have asserted that a certain natural relation obtains between Italian speakers’ tokens of “gatto” and cats. Or at least, I have asserted something about the way Italian speakers use the word “gatto”, which way presumably has something to do (...) with cats. The normativist claims, on the contrary, that what I have said is that in speaking Italian one ought to use the word “gatto” in a certain way, which way has something to do with cats. What I have done is endorse a certain proposal about how to use the word, which, if accepted, will have normative force. (shrink)

Two key elements define the modern-day version of a socially responsible corporation: (1) targeting business activities on value creation in three dimensions, and (2) maintaining relationships with stakeholders. In this article, we argue that a proper understanding of Corporate Social Responsibility (CSR) lies in the intrinsic link between these two elements. A relational approach to CSR is called for. Circles of stakeholders reflect the level of involvement of different stakeholders with a corporation and the dynamics of their relations. In a (...) globalising world, connecting corporations to outer-circle groups of stakeholders can be substantially rewarding. Partnerships with Non-Governmental Organisations (NGOs) present a useful strategy for governance for the benefit of all. (shrink)

Heidegger distinguishes between concern for things and solicitude for other Dasein. As Dasein is already being-in-the-world and being-with from the start, there is no need to define what another Dasein is to recognize it. In this paper it is argued that Dasein is thrown into circles of care, where the distinction between solicitude and concern is given. Although this undermines any attempts to regard a comatose patient as non-Dasein, it raises questions about Dasein's relations with animals. It is suggested that (...) Dasein's relations with animals could be captured by inserting another circle, for which the German word versorgen might be suitable. (shrink)

The paper examines the problematic understanding of “risk” in entrepreneurial literature that locates courage in either the loss orgain of having or in the difficulty and hardship of the doing. We argue in this paper that what is lost in this vernacular view of courage is a deeper notion of the subjective dimension of work and the social need of society. Grounded within the Catholic social and moral tradition, we find a richer notion of courage, which in (...) part corrects and rounds out the insufficient description of the vernacular understanding of courage in entrepreneurship. What we also find in this account of the virtues and subjective dimension of work is greater explanatory power of what happens to the entrepreneur in the work that he or she does. The end result of this analysis is a more spiritual, ethical and social understanding of entrepreneurship. (shrink)

We report the results of an experiment designed to determine the effects of psychological proximity—proxied by awareness of pain and friendship—on moral reasoning. Our study tests the hypotheses that a moral agent’s emphasis on justice decreases with proximity, while his/her emphasis on care increases. Our study further examines how personality, gender, and managerial status affect the importance of care and justice in moral reasoning. We find support for the main hypotheses. We also find that care should be split into two (...) components, one related to protection and the other to the preservation of relationships. Although gender does not affect moral reasoning directly, we find that it does so indirectly via personality, controlling for age, professional status, and professional background. We do not find a significant effect of managerial status on ethics of justice, but do find that holding a managerial position has a negative impact on ethics of care. Regarding personality, we detect significant positive effects of conscientiousness on ethics of justice and of neuroticism on ethics of care. (shrink)
