Whistleblowing refers to the disclosure by organization members of illegal, immoral, or illegitimate practices to persons or organizations that may be able to effect action. Most studies on the topic have been conducted in North American or European private sector organizations, and less attention has been paid to regions such as Turkey. In this study, we study the whistleblowing intentions and channel choices of Turkish employees in private and public sector organizations. Using data from 327 private sector and 405 (...) public sector employees, we find that public sector employees are more idealistic and less inclined to whistleblow externally and anonymously. Higher idealism among public sector employees does not moderate these effects. We find that private sector employees are more relativistic, and that they are more inclined to whistleblow through external and anonymous channels. More relativistic private sector employees are more likely to prefer external whistleblowing; however sector does not moderate the propensity to whistleblow anonymously. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:TRANSIENT NATURES AT THE EDGES OF HUMAN LIFE: A THOMISTIC EXPLORATION PHILIP SMITH, O.P. Providence College Providence, R.I. T:HE CONCEPT OF human nature as the intrinsic and wdical source of characteristic human a;ctivity has great mportanoe for natural law ethics. But olosely allied to the concept of human nature is the possibility of there being tmnsient natures in humans, and this rpossirbility has implications for human life at (...) its outer edges. What transient natures are wiill he discussed 1in detail below. Let us,say for now that they are the life principles of entities transition from one state of being to another. These forms enjoy only a temporary existence before they disappear and are replaced by other emerging forms.1 When applied to the outer limits of human existence, such transient natures offer useful insights for addressing the difficult problems of when personhood begins and when death occurs. Thomistic philosophy defines a human person a;s a combination of mrutte1· and,form, more oommorrly referred to as a unity of hody and soul.2 Relativie to the beginning of Jife and the 1 Such natures are discussed in William A. Wallace, 0.P., "Nature and Human Nature as the Norm in Medical Ethics,'' in Catholic Perspectives on Medical Morals, ed. E.D. Pellegrino et al., Philosophy and Medicine Series, Vol. 24 (Dordrecht-Boston: D. Reidel Publishing Co., 1989). This essay was originally presented at an international conference held at the Joseph and Rose Kenned,y Institute of Ethies of Georgetown UniYersity, October 13-16, 1986. For further background against which Wallace's discussion should be situated, see his "Nature as Animating: The Soul in the Human Sciences,'' The Thornist 49 (l985) : 612-6'18, and "The Intelligibility of Nature: A Neo-Aristotelian View," Rev,iew of Metaphysics 38 (1984): 33-56. 2 Thomas Aquinas, St., Surnrna Theologiae, I, q.29, a.4. 191 19Q PHILIP SMITH, O.P. onset of death, this philosophy of person raises the question of w:hen tihe soul is infused into the body and when :it is 1separated from it. Is the newly-fortiilized zygote capable of :receiving and sustaining the rational soul as its,substantirul form? Or must the genetic materials be informed by one or more transient natures before they achieve ithe internal unity and stability necessary :for personhood? At the end of life, the person dies when the soul leaves the body. Does personail death coincide with the death of the human organism as a whole? Or can the destruction of only an essential part of the body, e.g. tihe cerebral cortex, cause personal death by damaging the body so severely that it is simply incapable of supporting a :rational soul, even though the rest of the body remains intact and spontaneously alive? If so, is the remaining organism informed by a succession of transient substantiail forms that maintain its existence but at ever lower levels of life as it gradually declines toward total death? In examining these questions posed by the possibility of transient natures, my point of departure will be an analysis of transient natures themselves. Recently, William A. Wallace, O.P., has 'begun to eX!plore the philosophical meaning and implications of transient natures for issues such as these.a His findings will he summarized here. The insights gathered from the exploration of transient natures will next he applied to the questions of when personhood begins and when death occurs.

We investigate the dynamics of sensory integration for perceiving musical performance, a complex natural behavior. Thirty musically trained participants saw, heard, or both saw and heard, performances by two clarinetists. All participants used a sliding potentiometer to make continuous judgments of tension (a measure correlated with emotional response) and continuous judgments of phrasing (a measure correlated with perceived musical structure) as performances were presented. The data analysis sought to reveal relations between the sensory modalities (vision and audition) and to quantify (...) the effect of seeing the performances on participants' overall subjective experience of the music. In addition to traditional statistics, functional data analysis techniques were employed to analyze time-varying aspects of the data. The auditory and visual channels were found to convey similar experiences of phrasing but different experiences of tension through much of the performances. We found that visual information served both to augment and to reduce the experience of tension at different points in the musical piece (as revealed by functional linear modeling and functional significance testing). In addition, the musicians' movements served to extend the sense of phrasing, to cue the beginning of new phrases, to indicate musical interpretation, and to anticipate changes in emotional content. Evidence for an interaction effect suggests that there may exist an emergent quality when musical performances are both seen and heard. The investigation augments knowledge of human communicative processes spanning language and music, and involving multiple modalities of emotion and information transfer. (shrink)

The particle internal clock conjectured by de Broglie in 1924 was investigated in a channeling experiment using a beam of ∼80 MeV electrons aligned along the 〈110〉 direction of a 1 μm thick silicon crystal. Some of the electrons undergo a rosette motion, in which they interact with a single atomic row. When the electron energy is finely varied, the rate of electron transmission at 0° shows a 8% dip within 0.5% of the resonance energy, 80.874 MeV, for which (...) the frequency of atomic collisions matches the electron’s internal clock frequency. A model is presented to show the compatibility of our data with the de Broglie hypothesis. (shrink)

Drawing on interviews, this article examines how the third wave of the straight edge hardcore music scene can promote a gender-progressive image in light of evidence that suggests men's continued advantage over women in the scene. The author argues that this discrepancy can be explained by straight edgers' use of going rate comparisons that highlight the scene's “doings” and “not-doings” in ways that portray sXe favorably. By insisting that gender is no longer relevant, straight edgers then set up a going (...) rate of authenticity that is purportedly attainable by men and women. This going rate, however, ultimately reinstates gender boundaries sXers claim to erase. The author concludes the article by discussing the larger implications of doings and not-doings in going rate constructions and the performance of gender. (shrink)

God gave Scripture to his people for many reasons. Two of the most important are the subversive and the therapeutic. This article concentrates on the former. All humans are blind to the extent of their alienation from God, others, and themselves. Christians have begun the process of salvation, part of which includes growth in theocentric self-awareness, and God uses Scripture to promote this growth. Christians, however, face a formidable challenge at this point, because in our remaining sin, we can also (...) distort Scripture for sinful purposes. As a result, God has to use Scripture subversively and indirectly in order to enable Christians to read the Bible to promote the healing of inward deepening. A case for this agenda will be made from the Bible itself and the Christian tradition. (shrink)

We recast parts of decision theory in terms of channel theory concentrating on qualitative issues. Channel theory allows one to move between model theoretic and language theoretic notions as is necessary for an adequate covering. Doing so clarifies decision theory and presents the opportunity to investigate alternative formulations. As an example, we take some of Savage’s notions of decision theory and recast them within channel theory. In place of probabilities, we use a particular logic of preference. We introduce a logic (...) for describing actions separate from the logic of preference over actions. The structures introduced by channel theory that represent the decision problems can be seen to be an abstract framework. This frame-work is very accommodating to changing the nature of the decision problems to handle different aspects or theories about decision making. (shrink)

In this study we investigated sensorimotor processing of painful pressure stimulation on the lower back of patients with chronic lower back pain (CLBP) by using functional near-infrared spectroscopy (fNIRS) to measure changes in cerebral hemodynamics and oxygenation. The main objectives were whether patients with CLBP show different relative changes in oxy- and deoxyhemoglobin ([O2Hb] and [HHb]) in the supplementary motor area (SMA) and primary somatosensory cortex (S1) compared to healthy controls (HC). Twelve patients with CLBP (32 ± 6.1 years; (...) range: 24 – 44 years; 9 women) and twenty HCs (33.5 ± 10.7 years; range 22-61 years; 8 women) participated in the study. Painful and non-painful pressure stimulation was exerted with a thumb grip perpendicularly to the spinous process of the lumbar spine. A force sensor was attached at the spinous process in order control for pressure forces. Tactile stimulation was realized by a one-finger brushing. Hemodynamic changes in the SMA and S1 were measured bilaterally using a multi-channel continuous wave fNIRS imaging system and a multi-distant probe array. Patients with CLBP showed significant stimulus-evoked hemodynamic responses in [O2Hb] only in the right S1, while the healthy controls exhibited significant [O2Hb] changes bilaterally in both, SMA and S1. However, the group comparisons revealed no significant different hemodynamic responses in [O2Hb] and [HHb] in the SMA and S1 after both pressure stimulations. This non-significant result might be driven by the high inter-subject variability of hemodynamic responses that has been observed within the patients group. In conclusion, we could not find different stimulus-evoked hemodynamic responses in patients with CLBP compared to HCs. This indicates that neither S1 nor the SMA show a specificity for CLBP during pressure stimulation on the lower back. However, the results point to a potential subgrouping regarding task-related cortical activity within the CLBP group; a finding worth further research. (shrink)

The shape of hooks is of a taxonomic significance for cestoda. In order to characterize shape through numbers, a mathermatical model of drawings in two-dimensional space is proposed. This model is a synthetic one: first, it uses a large number of points on the edge of a hook-drawing as data; secondly, it enables to draw a specific hook by means of a computer after the parameters have been extracted from the data. The method does not use landmarks and therefore avoids (...) the difficulty of locating them. The ensuing discussion concerns description in common parlanceversus mathermatical language, the genesis of hooks and description in three-dimensional space. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Cycle of Violence and Feminist Constructions of Selfhood Jennifer L. Rike University ofDetroit Mercy Violence is the heart and secret soul ofthe sacred" (Girard 1977, 31). René Girard reaches this shocking conclusion by tracing the dynamics ofthe generation ofviolence in history, and the ingenious ways in which humanity has learned to funnel violence into ritual sacrifice to avoid apocalypse. His argument pivots upon his understanding ofhumanity as inherently (...) flawed, as fated to conflict in the struggle to survive. Ifthe sacred mechanism of ritual sacrifice is not deployed, violence takes on a power and personality all its own: "If left unappeased, violence will accumulate until it overflows its confines and floods the surrounding area. The role ofsacrifice is to stem this rising tide... and redirect violence into 'proper' channels" (10). Girard's theory about the violent origins ofthe sacred institutions of ritual sacrifice, law, and myth highlights perhaps the chief paradox of religion: it has been used to promote as much as to oppose violence. Today, as feminists explore how women in particular have been the objects ofsuch violence, they too have turned to Girard to understand this paradox, and yet most have ended up criticizing Girard for falsely universalizing typically Eurocentric and androcentric conceptions of humanity, violence, and religion (Shea, Kirk-Duggan, Nowak 24-6).' While they may be right on certain points, it is also possible that the rush offeminist scholars to charge 1 Nancy Jay has also criticized Girard for androcentrism, in particular because "he still grounds all community and culture on male control of male violence" (130). 22Jennifer L. Rike Girard with androcentrism reflects their own refusals to confront how the dark face of violence appears in women as well as in men. Rather than evaluating specific feminist criticisms ofGirard in this regard, I propose a more global approach—to delineate in greater detail how feminist constructions of selfhood need to be informed by Girard's theory of the violent origins ofthe sacred in order for feminism to achieve its own goals. In Girard's view, the ritual ofsacrifice and the law are generated out ofthe socio-psychological mechanisms ofacquisitive mimesis and scapegoating as the sacred's way of controlling violence. In ways he leaves largely implicit, these mechanisms reflect the devastating cyclical effects of violence upon its victims. Girard stops short of reflecting on the roles gender plays in the cyclical processes of violence, and yet, as my subsequent analyses shall demonstrate, there can be little doubt that women participate in these processes in ways both like and unlike men. Women have been scapegoated throughout history, but not all women end up as victims ofviolence and the rituals constructed to appease it. Nor do many women remain simply victims of the tides of violence: many repeat the cycle of victimization and themselves become perpetrators. Moreover, some escape the cycle ofviolence by a variety ofmeans whose patterns are well worth scrutinizing. My point is that women's modes of participation in the processes through which violence makes and remakes itself are far more complex than has been recognized, and merit our full attention. From the perspective of feminist constructions of selfhood, the question then becomes, how does gender affect one's experience of acquisitive mimesis and scapegoating, victimage and perpetration? To claim that only women are victims and only men—and the women they have co-opted—are perpetrators may be politically correct, but that claim ignores some hard but ultimately helpful truths about what women must do to bring about the changes necessary for revolutionizing our society by transforming its violent ways into peaceful ones. My plan, then, is to suggest how Girard might be used to advance the theory and praxis of feminism further by delving into the psychological mechanisms underlying acquisitive mimesis and scapegoating. I shall argue that using object relations theory to understand the ways in which violence splits the human psyche complements Girard's conception of acquisitive mimesis and scapegoating to disclose the complete dynamics ofthe cycle ofviolence. Such understanding is essential to feminist reconstructions of selfhood, because it makes the defeat of sexism and violence possible by exposing them at their roots.

The topic of Chief Executive Officer (CEO) compensation has been a focus of interest for many years. The purpose of this article is to explore the ethical dimensions of various generally accepted theories of CEO renumeration. We argue that a contractarian approach, based on the Kantian ethical framework, can be used to augment the existing contingent pay models.While the neoclassical economic model of the firm views the maximization of the shareholders'' wealth as the sole responsibility of top management, a contractarian (...) approach regards the balancing of various stakeholders'' interests as the primary task of top management. Ethical problems emerge when there are divergent, yet equally justifiable interests which compete in order to channel organizational resources to meet their own needs. In this situation, given the inherent ambiguities and ever present possibilities of multiple perspectives, it may not always be feasible to provide a categorical answer to the question of whether the CEO''s decisions are ethical. We suggest that a broad interpretation of the neoclassical theory of the firm, one that is grounded in Kantian and contractarian ethics, can serve as a basis for a reconciliation of different theories of executive compensation.

Media; It is a concept that encompasses all mass media. The most important task; the principle of impartiality and meeting the needs of the public for freedom of information. The media has facilitated the awareness, education, orientation and dissemination of all kinds of information in all fields. Today's media affects people's needs and desires positively or negatively. Media is like a double-edged sword. It has both positive and negative aspects. Human beings needed to know and understand each other after they (...) settled down. For this reason, people have tried to communicate with each other in various ways. As time passed, the means of communication used in society developed and written communication was changed from verbal communication. Before Islam, Arabs were in contact with the societies living around them. Arab tribes communicated among themselves through various means such as poetry, eulogy, oratory, setting mountain tops on fire, and homing pigeons. Since Arabia has been on two important trade routes for a long time, they made international communication through trade. The most important methods applied for communication in the period of ignorance; poetry, ode, oratory, club, fair etc. they used to eat. The Prophet started his first invitation by communicating with people in the first years of his prophethood. He held personal meetings with various tribesmen who came to Mecca during certain seasons. During the Meccan period, With the first revelation to the Prophet, he began to invite all humanity to Islam in the person of the Meccan society. The Prophet tried to convey his messages to the Meccan society by specifying the characteristics and purposes of his invitation. The notables of the Makkan polytheists did not take him seriously, The notables of the Makkan polytheists did not take him seriously, they mocked him and described him as a magician, poet, soothsayer, magician, separator, madman and demonized. Despite all these slanders, The Prophet continued to announce his message by communicating with everyone at all times and places. After the Prophet's migration from Mecca to Medina, communication and communication areas with the people in Medina became easier. The Prophet communicated with the kings and rulers of neighboring countries by sending letters to invite them to Islam. She also sent a letter to the Jews living in Medina, inviting them to abide by the agreements and promises they made. He strengthened communication with the Arab delegations who came to Medina to become Muslims and the delegations sent to meet with the Arab tribes. The Prophet communicated with the polytheists during the peace process with the Treaty of Hudaybiyah. On the one hand, the Tabuk Campaign to the Byzantine border to secure the borders of the Muslims in Medina became a means of communication for both the border and surrounding tribes. The Prophet's explanation, interpretation and hadiths of the Qur'an from the beginning of his prophethood have been the greatest media power for Muslims. The Prophet used various communication methods in his communication with people. While communicating with them, he took into account the characteristics of people and society.

The preparation of layers of amorphous Se by plasma-enhanced CVD using the hydride H2Se as precursor gas is described. Information concerning the structure of the films was obtained from Raman spectroscopy. The spectra of amorphous Se indicated that the dominant molecular structure is the eight-membered ring and/or a chain with Se8 molecular fragments. This material exhibited reversible photodarkening when illuminated at 77 K. In order to explain this phenomenon, we propose a mechanism which takes into account the role of (...) the lone-pair electron orbitals of Se in their contribution to structural ordering. Illumination can cause a distortion in the normal bonding direction between nearest-neighbour Se atoms and induce in this way intrinsic defect states located at the band edges. In the photo-darkened state, optical transition will occur between these defect states. (shrink)

The promises of nanotechnology have been framed by a variety of metaphors, that not only channel the attention of the public, orient the questions asked by researchers, and convey epistemic choices closely linked to ethical preferences. In particular, the image of the ‘therapeutic missile’ commonly used to present targeted drug delivery devices emphasizes precision, control, surveillance and efficiency. Such values are highly praised in the current context of crisis of pharmaceutical innovation where military metaphors foster a general mobilization of resources (...) from multiple fields of cutting-edge research. The missile metaphor, reminiscent of Paul Ehrlich’s ‘magic bullet’, has framed the problem in simple terms: how to deliver the right dose in the right place at the right moment? Chemists, physicists and engineers who design multi-functional devices operating in vitro can think in such terms, as long as the devices are not actually operating through the messy environment of the body. A close look at what has been done and what remains to be done suggests that the metaphor of the “therapeutic missile” is neither sufficient, nor even necessary. Recent developments in nanomedicine suggest that therapeutic efficacy cannot be obtained without negotiating with the biological milieu and taking advantage of what it affords. An ‘oikological’ approach seems more appropriate, more heuristic and more promising than the popular missile. It is based on the view of organism as an oikos that has to be carefully managed. The dispositions of nanocapsules have to be coupled with the affordances of the environment. As it requires dealing with nanoparticles as relational entities (defined by their potential for interactions) rather than as stable substances (defined by intrinsic properties) this metaphor eventually might well change research priorities in nanotechnology in general.

Do the nonverbal signals used to make social judgements differ depending on the type of judgement being made and what other nonverbal signals are visible? Experiment 1 investigated how nonverbal signals across three channels (face: angry/fearful, posture: expanded/contracted, lean: forward/backward), when viewed together, were used for judgements of emotion, threat, and status. Experiment 2 replicated Experiment 1 and explored how use of the body channels differed in making social judgements when the face channel was obscured. Both experiments found facial anger (...) linked to high anger, threat, and status ratings; facial fear was linked to low ratings. Expanded body posture increased threat and status judgements, while backward lean decreased anger and threat. With the face channel blocked (Experiment 2B), the influence of body posture increased across emotion, threat, and status judgements, while body lean was more consistent. Findings demonstrate that despite the face’s importance across types of social judgements, the body channels differentially contribute to judgements of emotion, threat and status. Further, they are differentially affected by the absence of facial information. How much face and body-related channels are used in social judgements is moderated by the type of judgement being made and the availability of other (particularly facial) channel information.

Graphs are among the most frequently used structures in Computer Science. Some of the properties that must be checked in many applications are connectivity, acyclicity and the Eulerian and Hamiltonian properties. In this work, we analyze how we can express these four properties with modal logics. This involves two issues: whether each of the modal languages under consideration has enough expressive power to describe these properties and how complex it is to use these logics to actually test whether a given (...) graph has some desired property. First, we show that these properties are not definable in a basic modal logic or in any bisimulation-invariant extension of it, like the modal μ-calculus. We then show that it is possible to express some of the above properties in a basic hybrid logic. Unfortunately, the Hamiltonian and Eulerian properties still cannot be efficiently checked. In a second attempt, we propose an extension of CTL* with nominals and show that the Hamiltonian property can be more efficiently checked in this logic than in the previous one. In a third attempt, we extend the basic hybrid logic with the ↓ operator and show that we can check the Hamiltonian property with optimal complexity in this logic. Finally, we tackle the Eulerian property in two different ways. First, we develop a generic method to express edge-related properties in hybrid logics and use it to express the Eulerian property. Second, we express a necessary and sufficient condition for the Eulerian property to hold using a graded modal logic. (shrink)

Traditional accounts of the role of learning in evolution have concentrated upon its capacity as a source of fitness to individuals. In this paper I use a case study from invasive species biology—the role of conditioned taste aversion in mitigating the impact of cane toads on the native species of Northern Australia—to highlight a role for learning beyond this—as a source of evolvability to populations. This has two benefits. First, it highlights an otherwise under-appreciated role for learning in evolution that (...) does not rely on social learning as an inheritance channel nor “special” evolutionary processes such as genetic accommodation (both of which many are skeptical about). Second, and more significantly, it makes clear important and interesting parallels between learning and exploratory behaviour in development. These parallels motivate the applicability of results from existing research into learning and learning evolution to our understanding of the evolution of evolvability more generally. (shrink)

One of the central debates among British chemists during the 1830s concerned the use of symbols to represent elements and compounds. Chemists such as Edward Turner, who desired to use symbolic notation mainly for practical reasons, eventually succeeded in fending off metaphysical objections to their approach. These objections were voiced both by the philosopher William Whewell, who wished to subordinate the chemists' practical aims to the rigid standard of algebra, and by John Dalton, whose hidebound opposition to abbreviated notation symbolized (...) the suspicion with which older British chemists perceived continental innovations. It is argued that the success of chemists like Turner in this debate reflects their larger success in the 1830s in achieving disciplinary autonomy and in beginning to align themselves more closely with prevailing chemical practice across the Channel.

In lieu of an abstract, here is a brief excerpt of the content:Refusals of Treatment and Requests for DeathTom L. Beauchamp (bio)It would be hard to overestimate the importance of two decisions on physician-assisted suicide delivered recently by the Ninth and Second Circuit Courts (Compassion in Dying v. State of Washington, 79 F.3d 790 (9th Cir. 1996) (en banc), aff’g 850 F.Supp. 1454 (W.D. Wash. 1994), rev’g 49 F.3d 586 (9th Cir. 1995); Quill v. Vacco, 80 F.3d 716 (2nd Cir. (...) 1996). They are the highest courts yet to render an opinion on this subject, and their decisions have set the stage for the U.S. Supreme Court to take one of two paths: It will either say that (1) all citizens have a liberty interest in physician-assisted suicide, or that (2) each state may set its own policy on such matters. Whichever path is elected, a right to request physician-assisted suicide is a virtual certainty, at least in some states.These opinions are later segments of an evolving legal history in which courts have held that no criminal liability exists for withholding or withdrawing a life-sustaining treatment when physicians are directed to do so by a patient or an authorized surrogate (see Alan Meisel 1992). The decriminalization of suicide and the right to refuse a life-sustaining treatment now appear to be evolving into a rule that a patient has a legal right to control his or her death, or at least to obtain a lethal prescription. We are at a delicate point in this evolving history. Neither in law nor in bioethics is the justification of physician assistance in suicide the received opinion at the present time, but support for physician assistance in dying could soon become the received opinion in both disciplines.The leading edge of the wedge producing these changes has been widespread acceptance of an extensive right to refuse treatment. This right is today axiomatic in even conservative quarters of bioethics, but 20 years ago it was far from axiomatic that all patients have a right to refuse treatment. Few at that time judged that it would be both immoral and illegal for a physician not to forgo treatment in the face of a competent, authoritative refusal of any form of medical service or treatment.The justification for assistance in bringing about death in medicine is an extension of the justification for letting patients die. Letting a patient die by accepting a valid refusal to continue in life is directly analogous to helping a patient die by accepting a valid request for help. The high value we place on [End Page 371] rights of autonomy thereby spills over from the right to refuse to the underexplored right to request active assistance. 1 As the autonomy interest in this choice increases, denial of help to the patient becomes more burdensome.Those who defend the view that euthanasia and physician-assisted suicide are morally prohibited typically assume that assistance involves an act of killing, that acts of killing are impermissible, and that a defensible distinction exists between killing and letting die. However, this distinction has proved difficult to explicate, and the category of killing often seems distant from the problem at hand. For example, it is an eccentric view that a physician who prescribes a lethal medication to a patient thereby kills the patient (or, for that matter, lets the patient die) when the patient voluntarily ingests the medication and dies. So poor are the conceptual understandings of “killing” and “letting die” that conceptual confusion abounds as to which term to use in almost all morally difficult and controversial cases.A common view is that “letting die” is a matter of “ceasing useless treatments” after which patients die (Gaylin, Kass, Pellegrino, and Siegler 1988). This account is attractive, but too narrow. “Letting die” occurs in medicine under at least two circumstances: cessation of treatment because it is useless and cessation of treatment because it has been refused (which can occur even with useful treatments). Neither conceptually nor morally is “ceasing useless treatment” the proper way to state the condition under which many “letting-die” cases occur. It follows that the type of action—killing or letting... (shrink)

Live streaming is a unique form of media that creates a direct line of interaction between streamers and viewers. While previous research has explored the social motivations of those who stream and watch streams in the gaming community, there is a lack of research that investigates intimate self-disclosure in this context, such as discussing sensitive topics like mental health on platforms such as Twitch.tv. This study aims to explore discussions about mental health in gaming live streams to better understand how (...) people perceive discussions of mental health in this new media context. The context of live streaming is particularly interesting as it facilitates social interactions that are masspersonal in nature: the streamer broadcasts to a larger, mostly unknown audience, but can also interact in a personal way with viewers. In this study, we interviewed Twitch viewers about the streamers they view, how and to what extent they discuss mental health on their channels in relation to gaming, how other viewers reacted to these discussions, and what they think about live streams, gaming-focused or otherwise, as a medium for mental health discussions. Through these interviews, our team was able to establish a baseline of user perception of mental health in gaming communities on Twitch that extends our understanding of how social media and live streaming can be used for mental health conversations. Our first research question unraveled that mental health discussions happen in a variety of ways on Twitch, including during gaming streams, Just Chatting talks, and through the stream chat. Our second research question showed that streamers handle mental health conversations on their channels in a variety of ways. These depend on how they have built their channel, which subsequently impacts how viewers perceive mental health. Lastly, we learned that viewers’ reactions to mental health discussions depend on their motivations for watching the stream such as learning about the game, being entertained, and more. We found that more discussions about mental health on Twitch led to some viewers being more cautious when talking about mental health to show understanding. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Cross-Examining Socrates. A Defense of the Interlocutors in Plato’s Early DialoguesMark L. McPherranJohn Beversluis. Cross-Examining Socrates. A Defense of the Interlocutors in Plato’s Early Dialogues. Cambridge: Cambridge University Press, 2000. Pp. xii + 416. Cloth, $69.95.This book is a valuable and thoroughly-researched contribution to the study of Plato's Socratic dialogues. Its fine qualities stem in part from its cathartic motivations: for years Beversluis suppressed his ever-growing reservations concerning (...) the "standard picture" of Socrates's interaction with his various interlocutors (16). On Beversluis's account, this position naively takes Socrates's own apologia at face-value, portraying him as a self-sacrificing soul-therapist who treats his corrupt, one-dimensional interlocutors fairly, despite their many carefully drawn faults (e.g., stupidity, vanity, and violence, followed by face-saving exits). Beversluis aims to rectify this picture by retrying Socrates in a class-action suit on behalf of Socrates's interlocutors—who, he thinks, the standard account has quite unfairly maligned (while it has simultaneously ignored Socrates's "dark side"; e.g., his unscrupulous, hypocritical, and harmful tactics [esp. his conscious use of fallacy]).Beversluis's book contains a Preface, Introduction, and seventeen chapters, finishing with a very good bibliography, general index, and indexes of passages cited, names, and modern authors. Chapter 1, "The Socratic Interlocutor," examines the structure of Plato's Socratic dialogues and the role of their interlocutors. Beversluis contrasts Plato's dialogues with those produced by Augustine, Anselm, Hume, and Berkeley, arguing that a key difference between them lies in the fact that Socrates is presented as having no system to expound, championing instead the intrinsic value of philosophizing. Also, Socrates's interlocutors are drawn from a "narrow sociological group," (29) and are unprepared for their (unpleasant) encounters with Socrates (31).Chapter 2, "Elenchus and sincere assent," cogently argues that the "say what you believe" constraint on Socrates's use of the elenchus represents a consensus in need of critical reappraisal. In particular, Beversluis contends that Socrates often relies on qualified or uncomprehending assent, and that our texts do not support the idea that Socrates never argues with the soul-ignoring intention to win an argument using faulty argumentation and willful misrepresentation of the interlocutor's statements.The next fourteen chapters closely assess Socrates's encounters with Crito, Ion, Hippias, Laches and Nicias, Charmides and Critias, Euthyphro, Cephalus, Polemarchus, Thrasymachus, Hippocrates, Protagoras, Gorgias, Polus, and Callicles. The book ends with a chapter on "The last days of the Socratic interlocutor," outlining the view that Plato's later work features non-elenctic spokesmen who are sensitive to the moral dangers of careless (i.e., Socrates's) elenchus-wielding.In his central chapters, Beversluis argues that "Saint Socrates" is in fact a philosophical [End Page 583] Jekyl and Hyde. Although scholars have celebrated the former philanthropic figure as a model philosopher, that has obscured his Hyde-like, predatory behavior towards innocents such as Euthyphro and Crito. However, here readers are themselves given a mixed bag: while Beversluis offers, for example, a detailed and smart defense of Cephalus against those who portray him as a petty-minded, superstitious, moral fraud (Chapter 9)—as well as sensitive, careful analyses of Socrates's less-than-clear arguments throughout—other chapters occasionally go overboard in their apologetic efforts. One example will have to suffice here.According to Beversluis, Euthyphro's typical characterization as a pretentious, dense, father-bashing, religious zealot who "would have done well in the Nazi Youth Movement," (R. F. Holland; 163), has drawn attention away from the fact that Socrates's treatment of Euthyphro is abusive and ineffectual. But although Beversluis rightly sees that the figure of Euthyphro is being used in a complex fashion by Plato, his account is marred in several ways. For example, although it is likely that Socrates does not himself possess complete definitions of virtue-concepts such as justice (164-169), unlike Euthyphro, Socrates can presumably provide elenchus-proof defenses of his own non-traditionalist claims. Again, while Socrates may overwhelm Euthyphro with his principles of proper definition (Eu. 5c-d, 6d-e), proceeding on uncomprehending, merely verbal agreement (169-177), Plato surely did not intend...

The college athletics environment within the USA is ethically complex and often controversial. From an academic standpoint, athletes are often viewed as a privileged class receiving undue benefit. Yet closer inspection reveals that student athletes are at risk psychologically, physically, and intellectually in ways that undermine development and flourishing. This reality stands in troubling contrast to the prosocial, virtue-based goals expressed by university mission statements. Given the role of sport in many university business models, college athletics invites scrutiny from a (...) business ethics standpoint. Using a humanistic leadership perspective (Pirson in: Humanistic management: protecting dignity and promoting well-being, Cambridge University Press, Cambridge, 2017), we organize our analysis around three challenges facing the college athletics system: (1) navigating the tension between claiming college athletes are amateurs rather than professionals; (2) defining the ethical edge between winning and winning fairly; and (3) moderating the insatiable drive to win while protecting student athlete well-being. We then articulate three strategies for successfully addressing these challenges: leadership role modeling, putting structural supports in place and holding people accountable. We argue that humanistic leadership and a ‘balanced motivational drive mindset’ (Lawrence and Nohria in: J Bus Ethics 128:383–394, 2002, https://doi.org/10.1007/s10551-014-2090-2 ; Pirson 2017) could help move college athletics from an economistic model toward a more humanistic model that prioritizes the dignity and well-being of its participants, particularly student athletes.

Telephone survey of 293 TV viewers in Minneapolis-St. Paul investigated how viewers evaluate ethical issues and problematic content in TV news and entertainment programs, and attitudes toward methods of controlling TV content. In rating eight hypothetical news and entertainment scenarios, viewers appeared more willing to accept ethical breaches in entertainment than in news programs. In evaluating the severity of general problems in TV programming, most viewers considered violence, adult themes, and a lack of family values to be big problems. Different (...) methods of controlling potentially problematic content were evaluated, with viewers overwhelmingly endorsing a system of ratings or warnings, as well as restricting content to certain times or channels. Governmental regulation as a form of controlling TV content was strongly rejected. This article demonstrates the usefulness and appropriateness of empirical research in involving the audience in an active role in the study of media ethics. (shrink)

The near-interface region of an epitaxial Ba 0.3 Sr 0.7 TiO 3 thin film grown on LaAlO 3 was found to consist of a high density of stacking faults bounded by partial dislocations. The stacking faults can extend over large distances . Various possible atomic configurations of the faults were considered. The atomic structures of the faults were identified using high-resolution electron microscopy and simulation as well as energy-filtered imaging. The and faults were found to lie predominately on the (...) {100} and {110} planes. The faults on , or have never been observed before in perovskites. The stacking faults on {100} have a structure consisting of a double layer of edge-sharing TiO 6 octahedra. The excess of Ti was detected by energy-filtered imaging. The formation of the extended stacking faults is probably related to a small amount of excess Ti during the film deposition, which may originate from the non-stoichiometry of the ceramic targets BaTiO 3 and SrTiO 3 . It is also enhanced by the misfit-induced compressive strain in the early stages of the film growth. (shrink)

A rank function for a directed graph G assigns elements of a well ordering to the vertices of G in a fashion that preserves the order induced by the edges. While topological sortings require a one-to-one matching of vertices and elements of the ordering, rank functions frequently must assign several vertices the same value.

Greed is one of the most common features of human nature, and it has recently attracted increasing research interest. The aims of this paper are to provide one of the first empirical investigations of the effects of greed on job performance and to explore the mediating role of the need for social status and perceived distributive justice. Using a working sample (N = 315) from China, the current study found that greed promoted both task and contextual performance through the (...) intermediary effect of the need for social status. At the same time, greed inhibited both types of performance through perceived distributive justice. These results confirmed our hypothesis that greed is a double-edged sword with opposite effects on one’s performance. The findings suggest that organizations should both address greedy employees’ social status concerns and ensure that they are treated fairly so that organizations can fully utilize the talents of greedy people and channel their energy in a beneficial direction.

What is “the relation of logic to philosophy?” Is “the traditional bond between logic and philosophy severed?” That the field of logic has evolved away from philosophy proper is supported by the apparent fact that most logic research today is carried out by members of university departments other than philosophy with the main logical concern of philosophy departments being elementary logic instruction. So, it appears to many observers that logic used to be a part of philosophy, but that at the (...) leading edge of its research and study it is no longer a basic or pure component of the field of philosophy. Although I myself do not believe this assessment, I will presume for the sake of discussion that it is widely believed. Against this supposed separation of logic from philosophy, I will show how to re-establish the connection. (shrink)

This analysis builds on the arguments of Manuel Castells, Jan Van Dijk and others who describe the emergence of network societies and networked global communication, economics, and political communication. Research has shown that those who are building communication networks that have political significance are also able to create new contacts, retrieve useful political information, distribute and discuss retrieved information with others, and establish contacts with various centers of power that provide them with new channels of access and political interactivity. Castells (...) and others argue that those who are left out of the network society and important political networks are members of a Fourth World of inequalities, growing poverty, and sustained disempowerment. In this paper, the study of digital democracy and networks of political communication is related to what Van Dijk calls polycentric politics and what Castells describes as variable political geometry. From the concepts of network society and digital democracy, a concept of network democracy is proposed. With this concept, the argument is made that the structurational aspects of digital democracy can be used to establish ICT systems that help new participants become part of networked power structures rather than serving to extend the participation of those who are already involved in systems of empowerment.

Philip Quinn, John A. O’Brien Professor at the University of Notre Dame from 1985 until his death in 2004, was well known for his work in the philosophy of religion, political philosophy, and core areas of analytic philosophy. Although the breadth of his interests was so great that it would be virtually impossible to identify any subset of them as representative, the contributors to this volume provide an excellent introduction to, and advance the discussion of, some of the questions of (...) central importance to Quinn in the last years of his working life. Paul J. Weithman argues in his introduction that Quinn’s interest and analyses in many areas grew out of a distinctive and underlying sensibility that we might call “liberal faith.” It included belief in the value of a liberal education and in rigorous intellectual inquiry, the acceptance of enduring religious, cultural, and political pluralism, along with a keen awareness of problems posed by pluralism, and a deeply held but non-utopian faith in liberal democratic politics. These provocative essays, at the cutting edge of epistemology, the philosophy of religion, philosophical theology, and political philosophy, explore the tenets of liberal faith and invite continuing engagement with the philosophical issues. “Philip Quinn was admired enormously throughout the world of professional philosophy.... His reputation for rigor, his tireless service to the profession, and his essentially ‘non-dogmatic,’ but philosophically sophisticated faith is widely admired... The essays in this volume are first-rate contemporary philosophy along with an excellent introduction to Quinn’s work.” —_Charles Taliaferro, St. Olaf College_ "The papers that form _Liberal Faith_ give insightful treatments of three types of questions: first, how can we conscientiously believe something when there are many people we admire who do not believe it, and what is the underlying relation here between justification and rationality; second, what does it mean to desire union with God, and can Christians properly believe in the possibility of eternal self-annihilation; third, how should liberal democracy accommodate the religious convictions of its members, whether some comprehensive doctrine such as a religion is required to justify a commitment to human equality, and whether there is an absolute moral prohibition on the state use of torture. The volume has an unusually good introduction putting the papers into dialog with each other and with the work of Philip Quinn. The papers are cohesive because the central themes of Philip Quinn's work hold together into a picture of how Christianity and Liberal Democracy fit together." —_John Hare, Noah Porter Professor of Philosophical Theology, Yale Divinity School _ “This is a collection of high quality essays dealing with various topics related to Philip Quinn’s work. The book makes an original contribution by virtue of its individual papers, each of which is new. These essays will be of interest to scholars and students who followed Quinn’s work, especially in philosophy of religion and political philosophy.“ —_John Greco, The Leonard and Elizabeth Eslick Chair in Philosophy, Saint Louis University _.

The development and utility of genetically modified crops for smallholders around the world is controversial. Critical questions include what traits and crops are to be developed; how they can be adapted to smallholders’ ecological, social and economic contexts; which dissemination channels should be used to reach smallholders; and which policy environments will enable the greatest benefits for smallholders and the rural poor. A key question is how the voices of smallholders who have experience with or desire to use GM technologies (...) enter the larger debate. Africa has the greatest number of smallholders and poor with the least exposure to GM crops. Because of the well-established use of GM crops in South Africa by commercial farmers, we formed a community of practice involving smallholders, extension, researchers, non-profits and agribusiness in KwaZulu-Natal to examine the conditions under which GM crops are used by smallholders, how smallholders interact with GM technologies and what insights smallholders and other stakeholders can provide regarding these questions. One of the advantages of the CoP approach is that it brings stakeholders together in a non-hierarchical way that encourages new ways of thinking and new partnerships. Such interaction around a specific project can enhance the voice of smallholders in a variety of ways. In our project, smallholder participants have increased their knowledge and can make better decisions about GM technologies, which had been barriers for them. Notably, they have also improved their knowledge of maize production practices, accessed new practice networks, and met new researchers and resource providers. They are now being integrated into these networks in a way that should improve their livelihoods and make the wants and needs of smallholders better known. Such knowledge and experience has improved their voice in agriculture and rural development discussions. (shrink)

Language research has come to rely heavily on large‐scale, web‐based datasets. These datasets can present significant methodological challenges, requiring researchers to make a number of decisions about how they are collected, represented, and analyzed. These decisions often concern long‐standing challenges in corpus‐based language research, including determining what counts as a word, deciding which words should be analyzed, and matching sets of words across languages. We illustrate these challenges by revisiting “Word lengths are optimized for efficient communication” (Piantadosi, Tily, & Gibson, (...) 2011), which found that word lengths in 11 languages are more strongly correlated with their average predictability (or average information content) than their frequency. Using what we argue to be best practices for large‐scale corpus analyses, we find significantly attenuated support for this result and demonstrate that a stronger relationship obtains between word frequency and length for a majority of the languages in the sample. We consider the implications of the results for language research more broadly and provide several recommendations to researchers regarding best practices. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:On Dialogue: An Essay in Free ThoughtMichael L. HallOn Dialogue: An Essay in Free Thought, by Robert Grudin; ix & 228 pp. New York: Houghton Mifflin Company, 1996, $23.95.In the fifth chapter of his recent book Robert Grudin touched on a question that had been vexing me since I began reading On Dialogue: An Essay in Free Thought. There, amongst his ruminations on the “Social Channels of Free (...) Thought,” Grudin recalls a luncheon celebration for his first trade book during [End Page 181] which one of the executives asked him: “Where in the bookstore would you display this book for sale?” In the four years it had taken him to write the book, Grudin had not given that question a moment’s thought. But it startled him into the realization that books are commodities that must be marketed; as a result he found himself confronting a powerful truth, “that money, like water, flows in channels, and that projects that ignore these channels are likely to come up dry.” More to the point: “These market channels give the American book industry, and hence current American literature, their overall shape. They largely dictate what will be written and read and what will not” (pp. 82–83).Grudin had not only anticipated my question, his response was a practical demonstration of the need for dialogic thinking, for a greater array of choices, questions and answers. I had been looking at On Dialogue from a kind of market perspective, or worse, an academic market perspective. Was it philosophy? Was it literature? Was it both, or neither? I was following the same familiar channels, but Grudin was telling me, quite explicitly, that my approach was unnecessarily limiting. Were I to employ, instead, the method of Renaissance copia that Grudin recommends as a propaedeutic to dialogic thinking, I would quickly discover that On Dialogue is certainly philosophy, and literary criticism, and that it partakes of the history of ideas, dabbles in personal memoir, and takes up theories of interpretation, and education, and creative writing, as well as various forms of psychotherapy, journalism, political theory, and economics.Grudin is obviously at home in the realm of literary criticism. His deft uses of Shakespeare’s Hamlet and of Henry James’s Daisy Miller advance his discussion of dialogic thinking, while at the same time offering focused interpretations of these works. And his examination of the Renaissance rhetorical practice of copia provides a stunning example of the way Grudin grounds his presentations in history and makes connections to other disciplines, thus extending the reach of his arguments. For instance, his reading of Plato’s Parmenides as a “Dialogue of the One and the Many” transforms Plato from an advocate of dialectic to a practitioner of dialogue: “The deep message of Plato’s Parmenides is that wholeness and fragmentation—the One and the Many—are valuable only as joint parameters. They cannot be objects of choice, because they are the nature of choice: they establish the playing field on which choices can be made” (p. 191).If all this makes On Dialogue sound like a congeries, in some respects it is, except that the force of Grudin’s discussion of “dialogic thinking” carries through the entire book and makes the whole cohere in a way that satisfies even when some of the parts occasionally begin to bewilder. His title may call to mind the 1980s literary critical trend spun off by the English translation of Mikhail Bakhtin’s The Dialogic Imagination (1981), but Grudin’s notions about dialogue are grounded more in Plato, Martin Buber and Hans-Georg Gadamer than in Bakhtin. His sense of dialogue is personal and transformative as much [End Page 182] as it is critical and interpretive. In fact, Grudin’s subtitle is no throwaway. His dialogic demonstrations, as they find their literary form, are the offspring of Michel de Montaigne’s Essays, as well as being firmly grounded in the writing of other Renaissance humanists such as Erasmus and Rabelais. In a book as multifarious as this, there will be many interesting (and a few not so interesting) loose ends. Grudin acknowledges this in chapters that sometimes end with a... (shrink)

BackgroundResearch and academic institutions use various delivery channels to deliver Research Integrity education in their communities. Yet there is no consensus on the best delivery method and the effectiveness of these channels in inculcating a positive RI culture varies across institutions. Hence, this study aimed to understand the preferences of the research community in Nanyang Technological University, Singapore.MethodsAn online survey was conducted on NTU research community to understand their experience with, and preference for each RI education mode offered in NTU. (...) The RI education modes surveyed in the general ranking question are Data Management Plan workshops, Epigeum e-Learning, Compass e-newsletter, and NTU policy on Research Integrity and Responsible Conduct of Research. There were 242 responses, comprising 50% research students, 32.2% research staff and 17.8% faculty members. Non-parametric statistical techniques were used to analyse preferences across different RI education modes and within sub-groups.ResultsMore than 92% of respondents subscribed to the importance of RI education, but with different preferences for education modes. With respect to RI education in NTU, Compass e-newsletters were ranked the lowest. Most felt that they were too wordy and unengaging, making it difficult to absorb information. Similarly, Epigeum e-Learning and ‘policy’ were found to be too lengthy in presentation. The compulsory NTU RI education modes enjoyed higher participation rates of 70–80% compared with 32–37% for the self-regulated modes. This suggests that regulatory mechanisms are still necessary to promote participation in RI education, and thus, core RI education content should be made compulsory in research/academic institutions. Although Epigeum is a compulsory course, some may not have participated in the programme due to technical issues or they might have forgotten to participate in the programme within the permissible timeframe. For all four RI education modes in NTU, the lack of awareness was among the top cited reasons for not participating.ConclusionsMost NTU researchers perceived RI education positively although they may have reservations for some approaches. Conversely, e-Learning is favored over all the other modes except for the mode of Policy. Findings from this study are useful for improving the design of RI education strategies to be more appealing to the research community by enhancing user experience in terms of user-friendliness, relevance to specialisation, providing concise information and better presentation of materials For institutions with similar modes of RI education as NTU, these results may be relevant in improving participation rates and presentation of RI education modes, such as the use of infographics and more concise information.

Austin attacks the view that language is referential, based on the simplistic division of utterances into the ‘descriptive’ and ‘evaluative’, using his notion of performative utterances. Such utterances, in the appropriate circumstances, are neither descriptive nor evaluative, but count as actions, i.e., create the situation rather than describing or reporting on it. In saying ‘I promise to go’ one is making a promise, not stating that one is making it. A performative promise is not, and does not involve, the (...) statement that one is promising. It is an act of a distinctive sort, the very sort named by the performative verb. And, according to Austin, making explicit what one is doing is not describing what one is doing or stating that one is doing it. (shrink)

BackgroundStructured, systematic methods to formulate consensus recommendations, such as the Delphi process or nominal group technique, among others, provide the opportunity to harness the knowledge of experts to support clinical decision making in areas of uncertainty. They are widely used in biomedical research, in particular where disease characteristics or resource limitations mean that high-quality evidence generation is difficult. However, poor reporting of methods used to reach a consensus – for example, not clearly explaining the definition of consensus, or not stating (...) how consensus group panellists were selected – can potentially undermine confidence in this type of research and hinder reproducibility. Our objective is therefore to systematically develop a reporting guideline to help the biomedical research and clinical practice community describe the methods or techniques used to reach consensus in a complete, transparent, and consistent manner.MethodsThe ACCORD project will take place in five stages and follow the EQUATOR Network guidance for the development of reporting guidelines. In Stage 1, a multidisciplinary Steering Committee has been established to lead and coordinate the guideline development process. In Stage 2, a systematic literature review will identify evidence on the quality of the reporting of consensus methodology, to obtain potential items for a reporting checklist. In Stage 3, Delphi methodology will be used to reach consensus regarding the checklist items, first among the Steering Committee, and then among a broader Delphi panel comprising participants with a range of expertise, including patient representatives. In Stage 4, the reporting guideline will be finalised in a consensus meeting, along with the production of an Explanation and Elaboration document. In Stage 5, we plan to publish the reporting guideline and E&E document in open-access journals, supported by presentations at appropriate events. Dissemination of the reporting guideline, including a website linked to social media channels, is crucial for the document to be implemented in practice.DiscussionThe ACCORD reporting guideline will provide a set of minimum items that should be reported about methods used to achieve consensus, including approaches ranging from simple unstructured opinion gatherings to highly structured processes.

Significant research has been devoted to detecting people in images and videos. In this paper we describe a human de- tection method that augments widely used edge-based fea- tures with texture and color information, providing us with a much richer descriptor set. This augmentation results in an extremely high-dimensional feature space (more than 170,000 dimensions). In such high-dimensional spaces, classical machine learning algorithms such as SVMs are nearly intractable with respect to training. Furthermore, the number of training samples is much (...) smaller than the dimensionality of the feature space, by at least an order of magnitude. Finally, the extraction of features from a densely sampled grid structure leads to a high degree of multicollinearity. To circumvent these data characteristics, we employ Partial Least Squares (PLS) analysis, an effi- cient dimensionality reduction technique, one which pre- serves significant discriminative information, to project the data onto a much lower dimensional subspace (20 dimen- sions, reduced from the original 170,000). Our human de- tection system, employing PLS analysis over the enriched descriptor set, is shown to outperform state-of-the-art tech- niques on three varied datasets including the popular INRIA pedestrian dataset, the low-resolution gray-scale Daim- lerChrysler pedestrian dataset, and the ETHZ pedestrian dataset consisting of full-length videos of crowded scenes.

Recent developments in biotechnology allow for the generation of increasingly complex products out of human tissues, for example, human stem cell lines, synthetic embryo-like structures and organoids. These developments are coupled with growing commercial interests. Although commercialisation can spark the scientific and clinical promises, profit-making out of human tissues is ethically contentious and known to raise public concern. The traditional bioethical frames of gift versus market are inapt to capture the resulting practical and ethical complexities. Therefore, we propose an alternative (...) approach to identify, evaluate and deal with the ethical challenges that are raised by the increasing commercialisation of the exchange of sophisticated human tissue products. We use organoid technology, a cutting-edge stem cell technology that enables the cultivation of ‘mini-organs’ in a dish, as an example. First, we examine the moral value of organoids and recognise them as hybrids that relate to persons and their bodies as well as to technologies and markets in ambiguous ways. Second, we show that commercialisation of organoids is legitimised by a detachment of the instrumental and commercial value of organoids from their associations with persons and their bodies. This detachment is enacted in steps of disentanglement, among which consent and commodification. Third, we contend that far-reaching disentanglement is ethically challenging: (1) Societal interests could be put under pressure, because the rationale for commercialising organoid technology, that is, to stimulate biomedical innovation for the good of society, may not be fulfilled; (2) The interests of donors are made subordinate to those of third parties and the relational moral value of organoids may be insufficiently recognised. Fourth, we propose a ‘consent for governance’ model that contributes to responsible innovation and clinical translation in this exciting field. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Place: Towards a Geophilosophy of Photography by Ali ShobeiriElizabeth. L. CoxPlace: Towards a Geophilosophy of Photography BY ALI SHOBEIRI Leiden, The Netherlands: Leiden University Press, 2021In his most recent work, Place: Towards a Geophilosophy of Photography, Ali Shobeiri skilfully demonstrates both the importance of, and fluid ways in which, place plays a dynamic role in the understanding and stories nestled within the seeing and evaluating of photographs and (...) photography. Bringing together the worlds of photography, geography, and philosophy to create an interdisciplinary theoretical understanding of place in relation to photography, Shobeiri has expertly unearthed a nuanced, exciting way of considering the photographic process and images.Shobeiri, an Assistant Professor of Photographic Studies and Visual Arts Theory at Leiden University, brings his knowledge and expertise of visual culture, photographic theory, human geography, and philosophy to the fore in his latest publication. His knowledge, passion, personal interest in photography, and his critical thought come through nicely in his writing, and it is clear that the development of Shobeiri’s ideas and framework have been given a lot of thought, time, and energy. This book meaningfully speaks to those interested in a discussion of place within the realm of photography, evidenced through the depth of knowledge and sheer detail explored within this book.Inspired by his own experience as a photographer and influenced by Edward Casey’s “delimited” definition of place, Shobeiri explores how place is never simply presented or fixed (11). It is here that he expertly uses photography to do this across six different yet clearly complimentary chapters. Critically, there is no way to give a succinct overview of the chapters of this book without losing meaning and diluting Shobeiri’s message; the book is rich, deeply detailed, embedded within philosophical thought, and is nuanced throughout, which is important to remember when reading this non- fiction piece of work.In the first chapter, Shobeiri provides a phenomenological exploration of the importance of the photographer’s body both as a lived experience and a physical entity. He then juxtaposes this duality to the lived [End Page 136] place of the photograph, returning to the notion of fixedness and using the idea of belonging to explore the photographer’s body and the photographic experience as a lived place. The next chapter discusses spatiality and time, and the way in which space is temporalized, using key influences such as Roland Barthes and Susan Collins to illustrate the argument. Central to this is the idea that a photograph captures time, but also aims at space, which raises questions about what this means for the space before the lens. In chapters 3 and 4, the author argues that the photograph itself travels through space, and highlights the importance of the photographic place, allowing us to “bestow meaning upon that space on the photograph’s surface” (67). Interestingly, Shobeiri points to philosophy to help the reader understand this, such as Jacques Derrida, and uses more familiar images and scholarly thought from NASA to discuss blind field and the liminality of photographic place. Chapter 5 moves away from location and journeys the reader to a discussion of places viewed as moment of encounter, specifically considering the spectator and the photograph. This evolves further in the sixth and final chapter insofar as it explores the transition and translation of the photographed place to the communication of the content of the image and the agency of the photograph. Shobeiri finishes with a simple yet engaging epilogue, several helpful notes, and a plethora of references which are useful for further reading.Place: Towards a Geophilosophy of Photography is genuinely interesting, centred within academic scholarship, and employs the thought of theorists that readers of Environment, Space, Place will undoubtably recognise. Scholarly figureheads such as Jacques Derrida, Alain Badiou, and Michel Foucault, space and place authorities such as Tim Cresswell, Tim Ingold, and Doreen Massey, and art aficionados such as Roland Barthes, Susan Collins, and John Berger frequent the pages. Familiar artistic names are also drawn upon, including Ansel Adams, Gert Jan Kocken, and Gerhard Richter, which soften the strong academic tones that this book voices. This work is clearly sophisticated in terms of lexicon and ideas, however... (shrink)

Training under high interference conditions through interleaved practice results in performance suppression during training but enhances long-term performance relative to repetitive practice involving low interference. Previous neuroimaging work addressing this contextual interference effect of motor learning has relied heavily on the blood-oxygen-level-dependent response using functional magnetic resonance imaging methodology resulting in mixed reports of prefrontal cortex recruitment under IP and RP conditions. We sought to clarify these equivocal findings by imaging bilateral PFC recruitment using functional near-infrared spectroscopy while (...) discrete key pressing sequences were trained under IP and RP schedules and subsequently tested following a 24-h delay. An advantage of fNIRS over the fMRI BOLD response is that the former measures oxygenated and deoxygenated hemoglobin changes independently allowing for assessment of cortical hemodynamics even when there is neurovascular decoupling. Despite slower sequence performance durations under IP, bilateral PFC oxygenated and deoxygenated hemoglobin values did not differ between practice conditions. During test, however, slower performance from those previously trained under RP coincided with hemispheric asymmetry in PFC recruitment. Specifically, following RP, test deoxygenated hemoglobin values were significantly lower in the right PFC. The present findings contrast with previous behavioral demonstrations of increased cognitive demand under IP to illustrate a more complex involvement of the PFC in the contextual interference effect. IP and RP incur similar levels of bilateral PFC recruitment, but the processes underlying the recruitment are dissimilar. PFC recruitment during IP supports action reconstruction and memory elaboration while RP relies on PFC recruitment to maintain task variation information in working memory from trial to trial. While PFC recruitment under RP serves to enhance immediate performance, it does not support long-term performance. (shrink)

We study human performance in two classical NP‐hard optimization problems: Set Cover and Maximum Coverage. We suggest that Set Cover and Max Coverage are related to means selection problems that arise in human problem‐solving and in pursuing multiple goals: The relationship between goals and means is expressed as a bipartite graph where edges between means and goals indicate which means can be used to achieve which goals. While these problems are believed to be computationally intractable in general, they become (...) more tractable when the structure of the network resembles a tree. Thus, our main prediction is that people should perform better with goal systems that are more tree‐like. We report three behavioral experiments which confirm this prediction. Our results suggest that combinatorial parameters that are instrumental to algorithm design can also be useful for understanding when and why people struggle to choose between multiple means to achieve multiple goals.

Research using economic decision-making tasks has established that direct reciprocity plays a role in prosocial decision-making: people are more likely to help those who have helped them in the past. However, less is known about how considerations of mutual exchange influence decisions even when the other party’s actions are unknown and direct reciprocity is therefore not possible. Using a two-party economic task in which the other’s actions are unknown, study 1 shows that prosociality critically depends on the potential (...) for mutual exchange; when the other person has no opportunity to help the participant, prosocial behavior is drastically reduced. In study 2, we find that theories regarding the other person’s intentions influence the degree of prosociality that participants exhibit, even when no opportunity for direct reciprocity exists. Further, beliefs about the other’s intentions are closely related to one’s own motivations in the task. Together, the results support a model in which prosociality depends on both the social conditions for mutual exchange and a mental model of how others will behave within these conditions, which is closely related to knowledge of the self.

The use of cross-media and transmedia-based art installation has generated new ways for the audience to appreciate, understand and experience art. Transmedia, the integration of multiple media forms to augment a single narrative, has not only been largely used in commercial films, but has also been used by artists to communicate their message more effectively. In this article, we explore some remarkable multi-channel video installations and transmedia artworks to highlight how this technology has shaped new uses of technology as a (...) new medium to express artistic concepts. We discuss one artwork, an experimental collaboration between artists and scientists, entitled Reefs on the Edge, which communicates valuable information about climate change to a general audience.

Ambitious targets to reduce greenhouse gas emissions from agriculture have been set by both national governments and their respective livestock sectors. We hypothesize that farmer self-identity influences their assessment of climate change and their willingness to implement measures which address the issue. Perceptions of climate change were determined from 286 beef/sheep farmers and evaluated using principal component analysis. The analysis elicits two components which evaluate identity, and two components which evaluate behavioral capacity to adopt mitigation and adaptation measures. Subsequent (...) Cluster Analyses reveal four farmer types based on the PCA scores. ‘The Productivist’ and ‘The Countryside Steward’ portray low levels of awareness of climate change, but differ in their motivation to adopt pro-environmental behavior. Conversely, both ‘The Environmentalist’ and ‘The Dejected’ score higher in their awareness of the issue. In addition, ‘The Dejected’ holds a high sense of perceived risk; however, their awareness is not conflated with an explicit understanding of agricultural GHG sources. With the exception of ‘The Environmentalist’, there is an evident disconnect between perceptions of agricultural emission sources and their contribution towards GHG emissions amongst all types. If such linkages are not conceptualized, it is unlikely that behavioral capacities will be realized. Effective communication channels which encourage action should target farmers based on the groupings depicted. Therefore, understanding farmer types through the constructs used in this study can facilitate effective and tailored policy development and implementation. (shrink)

We present a population density and moment-based description of the stochastic dynamics of domain $${\text{Ca}}^{2+}$$ -mediated inactivation of L-type $${\text{Ca}}^{2+}$$ channels. Our approach accounts for the effect of heterogeneity of local $${\text{Ca}}^{2+}$$ signals on whole cell $${\text{Ca}}^{2+}$$ currents; however, in contrast with prior work, e.g., Sherman et al. :985–995, 1990), we do not assume that $${\text{Ca}}^{2+}$$ domain formation and collapse are fast compared to channel gating. We demonstrate the population density and moment-based modeling approaches using a 12-state Markov chain (...) model of an L-type $${\text{Ca}}^{2+}$$ channel introduced by Greenstein and Winslow :2918–2945, 2002). Simulated whole cell voltage clamp responses yield an inactivation function for the whole cell $${\text{Ca}}^{2+}$$ current that agrees with the traditional approach when domain dynamics are fast. We analyze the voltage-dependence of $${\text{Ca}}^{2+}$$ inactivation that may occur via slow heterogeneous domain [ $${\text{Ca}}^{2+}$$ ]. Next, we find that when channel permeability is held constant, $${\text{Ca}}^{2+}$$ -mediated inactivation of L-type channels increases as the domain time constant increases, because a slow domain collapse rate leads to increased mean domain [ $${\text{Ca}}^{2+}$$ ] near open channels; conversely, when the maximum domain [ $${\text{Ca}}^{2+}$$ ] is held constant, inactivation decreases as the domain time constant increases. Comparison of simulation results using population densities and moment equations confirms the computational efficiency of the moment-based approach, and enables the validation of two distinct methods of truncating and closing the open system of moment equations. In general, a slow domain time constant requires higher order moment truncation for agreement between moment-based and population density simulations. (shrink)
