It is important to understand the processes behind how and why individuals emerge as leaders, so that the best and most capable individuals may occupy leadership positions. So far, most literature in this area has focused on individual characteristics, such as personality or cognitive ability. While interactions between individuals and context do get research attention, we still lack a comprehensive understanding of how the social context at work may help individuals to emerge as leaders. Such knowledge could make an important (...) contribution toward getting the most capable, rather than the most dominant or narcissistic individuals, into leadership positions. In the present work, we contribute toward closing this gap by testing a mediation chain linking a leader's leader self-awareness to a follower's leadership emergence with two time-lagged studies (nstudy1 = 449, nstudy2 = 355). We found that the leader's leader self-awareness was positively related to (a) the follower's leadership emergence and (b) the follower's nomination for promotion and that both relationships were serially mediated by the follower's self-leadership and the follower's leader self-efficacy. We critically discuss our findings and provide ideas for future research. (shrink)

© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:A Chance to CutBruce H. CampbellMy gloved hand reaches for progressively sharper surgical instruments. The prior radiation therapy and recurrent cancer [End Page E3] have made his neck tissues as stiff and hard as an old block of wood; everything appears too dull and feels too dry under the bright operating room lights. I push, dissect, urge, divide, prod, and spread with little effect.The nursing staff keeps to its (...) routine—completing computer entries, retrieving supplies, counting sponges—only intermittently aware that things are not going well at the point of attack. Nondescript music plays softly and the anesthesia machine continues to emit its gentle sounds. The junior resident—assisting me with the first of many neck dissections she will see during her five years of training—grips the retractor as she has been told and dabs the wound periodically to clear any blood or fluid.I glance up to recheck the CT scan. It confirms that this man’s recurrent cancer is just below the next layer of neck muscles. There are also some large blood vessels and major nerves nearby. I am confident, though, that I will be able to expose the mass, protect all of the critical structures, and safely remove the cancer.Curing cancer with surgery is no small feat, mind you. Cancer is, after all, a molecular disease not easily confined to an obvious lump, even though we sometimes refer to a malignant mass being “like a walnut” or “as hard and round as a marble.” The actual disease rests deep inside each cancer cell where the genetic code—the DNA—makes mistake–after–mistake. If cancer is to be cured with a surgical procedure, the surgeon must remove every last cell that is capable of making the same nonsensical, life–threatening error. Given Science’s rudimentary knowledge of cancer cell dynamics and signaling, it’s a miracle that surgery ever works. Yet, we continue to try. And we succeed just often enough to keep on trying.I rearrange the retractors and alter my approach. My mentors would have known what to do next, I imagine. My training included time well–spent with brilliant and technically–gifted surgeons. How would they have approached this case? Their experience and instincts might have told them to open the wound more widely, work the lateral and deep margins first, or position the instruments differently.Perhaps, one of my mentors would have attacked this man’s tumor using the same approach I am attempting but would have known exactly where to exploit some area of weakness that I cannot locate. A few swift, confident moves and he would have held the mass in his hands. “That’s it. We’re done,” he would have said.I met this patient several months ago when his cancer was first discovered and have seen him throughout his course of treatment. Recently, his daughter had accompanied him to the office to review his options. “Treatment has been rugged, Doc,” he reminded me. “The cancer’s still there and they said I can’t get any more radiation. Chemo would only prolong things. I don’t really want surgery, but what choice do I have if I want to be cured?”“Supportive care is an option, but the only curative approach is surgery.”“Well, I’m not ready to quit yet, Doc. I got grand-kids, y’know. I want to watch them grow up.” He nodded to his daughter. “I’m in charge of spoiling her little boys.”The daughter smiled. We crowded around the computer screen to look at the scans. I showed them how the tumor was invading and destroying surrounding structures. I described the surgery and the risks.“There are many things I will not know about your tumor until we are actually in the operating room,” I explained. Surgery in the setting of recurrent disease involves a series of on–the–spot decisions and course corrections. The odds of success are unknowable. “Sometimes, the only way to find out if we can remove the cancer is simply to try.”He took a deep breath and looked at his daughter. “Well then, Doc, if surgery is the only...

The relative importance of the Jones’ [Jones, T. M.: 1991, Academy of Management Review 16(2), 366–395] six components of moral intensity was measured using a conjoint experimental design. The most important components influencing ethical perceptions were: probability of effect, magnitude of consequences, and temporal immediacy. Contrary to previous research, overall social consensus was not an important factor. However, consumers exhibit distinctly different patterns in ethical evaluation, and for approximately 15% of respondents social consensus was the most important dimension.

In lieu of an abstract, here is a brief excerpt of the content:SCRIPTURAL GROUNDS FOR CONCRETE MORAL NORMS 1. Is JJ1oral Theology Really Theology? 0 BE CHRISTIAN theology moral theology ought to be firmly grounded in the Bible as understood in the living tradition of the Church. Yet the moralist who asks help from the biblicist today is to be met with a host cf objections.1 I will mention eight I have encountered: l) Attempts to develop a biblical theology unified (...) by some central concept such as promise fulfillrnent, salvation history, or liberation have all broken down. The Bible contains many diverse, even contradictory, or at least dialectically opposed theologies and ethical To harmonize them is to distort them.2 1 See Charles E. Curran and Richard A.

Birch and Larry Rasmussen, Bible and Ethics in the Christian Life (l\finneapolis: Augsburg, 1976). Valuable hermeneutical suggestions ·will be found in Rudolf Schnackenburg, The Moral Teaching of the New Testarnent (New York: Seabury, 1973) and the two works of Pierre Grelot, Sens Oh1·etien de l'Ancien Testarnent 2nd ed.

ASHLEY, O.P. 2) The predominant literary form of the Bible which holds it together is narrative. How then can we draw moral principles from such narratives? To treat them as cautionary tales with an obvious moral does great injustice to their psychological richness and moral ambiguity.3 3) The Bible primarily uses not a literal but a symbolic type of language appropriate to the mysteries it reveals. These symbols or images can mold ethical attitudes and affections but they cannot be reduced to literal concrete moral norms without danger of distortion.4 4) Granted that both Testaments contain many prescriptive statements, they are so embedded in their historical contexts and so related to situations that are now obsolete, that it is impossible to believe they oblige us today. Can we really believe that women must be veiled (I Cor 11: 10) or that slaves should obey their masters (Ti 2: 9)? 5 5) The early Church, and perhaps Jesus himself, expected the eschaton within a lifetime. Consequently, the New Testament provides only an " interim ethics " which is useless as a guide in a continuing sinful world.6 6) We read in Ephesians 2: 15 that Jesus "in his own flesh John H.

He is especially critical of the first method and gives preference to the last. s" To put the matter most sharply, Jesus does not provide a valid ethics for today. His... (shrink)

Do humans start life with the capacity to detect and mentally represent the objects around them? Or is our object knowledge instead derived only as the result of prolonged experience with the external world? Are we simply able to perceive objects by watching their actions in the world, or do we have to act on objects ourselves in order to learn about their behavior? Finally, do we come to know all aspects of objects in the same way, or are some (...) aspects of our object understanding more epistemologically privileged than others? -/- "The Origins of Object Knowledge" presents the most up-to-date survey of the research into how the developing human mind understands the world of objects and their properties. It presents some of the best findings from leading research groups in the field of object representation approached from the perspective of developmental and comparative psychology. Topics covered in the book all address some aspect of what objects are from a psychological perspective; how humans and animals conceive what they are made of; what properties they possess; how we count them and how we categorize them; even how the difference between animate and inanimate objects leads to different expectations. The chapters also cover the variety of methodologies and techniques that must be used to study infants, young children, and non-human primates and the value of combining approaches to discovering what each group knows. -/- Bringing together leading researchers, communicating the most contemporary and exciting findings within the field of object representation, this volume will be an important work in the cognitive sciences, and of interest to those across the fields of developmental and comparative psychology.

Alasdair MacIntyre once famously asked “is patriotism is a virtue?” but never quite answered the question. In this paper, I seek to provide a more concrete response by analyzing whether patriotism fits the model of an Aristotelian natural virtue. Since Aristotle himself does not offer an extensive discussion of patriotism as a virtue, I take my inspiration from St. Thomas who does clearly regard something like patriotism as a part of the natural virtue of piety. After exploring the significance of (...) Thomas’s key claim that patriotism is owed to the “sources of our being,” I sketch the structure of moral virtue in Aristotle with an emphasis on his claim that all the virtues are. Finally, I show how patriotism fits the model of an Aristotelian natural moral virtue and conclude by addressing a few natural objections. (shrink)

A unifying theory of general anesthetic-induced unconsciousness must explain the common mechanism through which various anesthetic agents produce unconsciousness. Functional-brain-imaging data obtained from 11 volunteers during general anesthesia showed specific suppression of regional thalamic and midbrain reticular formation activity across two different commonly used volatile agents. These findings are discussed in relation to findings from sleep neurophysiology and the implications of this work for consciousness research. It is hypothesized that the essential common neurophysiologic mechanism underlying anesthetic-induced unconsciousness is, as with (...) sleep-induced unconsciousness, a hyperpolarization block of thalamocortical neurons. A model of anesthetic-induced unconsciousness is introduced to explain how the plethora of effects anesthetics have on cellular functioning ultimately all converge on a single neuroanatomic/neurophysiologic system, thus providing for a unitary physiologic theory of narcosis related to consciousness.

The language of propositional modal logic is extended by the introduction of sequents. Validity of a modal sequent on a frame is defined, and modal sequent-axiomatic classes of frames are introduced. Through the use of modal algebras and general frames, a study of the properties of such classes is begun.

In two studies we investigated whether people evidence an effect of moral contamination with respect to hypothetical organ transplants. This was achieved by asking participants to make judgements after presenting either positive or negative background information about the donor. In the first study, positive/negative background information had a corresponding effect on three judgements with attitudes to a heart transplant most pronounced by negative background information relative to good information and controls. This effect was replicated in the second study with both (...) heart and liver transplantation. Negative effects were stronger than positive effects in all conditions consistent with a negativity bias, but again stronger with regards to organs than controls. These results confirm findings from surveys that reveal real patients are concerned about moral contamination following organ transplantation and show that this bias in evident even in hypothetical, non-life-threatening scenarios. In a third study we found a significantly stronger moral contagion effect in Japanese relative to English participants, suggesting that concerns about moral contagion may be moderated by culture.

Although young children might be uncertain about the nature of certain representations, most modern adults would explicitly maintain that photographs have no ongoing physical connection the objects that they depict. We demonstrate here in three studies that destruction of a photograph of a sentimental object produces significantly more electrodermal activity than destruction of photographs of other control objects. This response is not attributable to anxiety about being observed whilst destroying the picture, nor is it entirely due to simple visual association (...) ‐ the same response occurs when the photograph does not resemble the object. We suggest that this effect may reflect a tacit acceptance of “sympathetic magic”. (shrink)

Despite the popularity of equality as a political value, egalitarianism as a political theory has never, I think, been fully or successfully defended. I aim in this paper to begin the defense of such a view. The egalitarianism I have in mind has as its ideal a condition of equal wellbeing for all persons at the highest possible level of well-being, i.e. maximum equal well-being. Egalitarianism holds that society should be arranged so as to promote and maintain this state. Defending (...) such a view involves, as I see it, three tasks. First, the ideal I have Just mentioned must be made clearer and more specific and its implications for the distribution of particular goods such as material possessions and liberty must be revealed. Second, positive arguments must be given in support of an equal distribution of well-being as a requirement of morality and Justice. And, thirdly, arguments to the effect that there are Just or Justified inequalities which seriously outweigh the claims of equality must be rebutted. (shrink)
