The new discipline of exobiology formed from the intertwining of origin of life research with the search for life or its building blocks on other planets, from 1957-1973. The field was inherently highly interdisciplinary, yet it coalesced very quickly and was responsible in its first twenty years for numerous important contributions to twentieth century life science and planetary sciences such as climatology, the study of mass extinctions, etc. NASA played a very important role in catalyzing the rapid consolidation of exobiology, (...) both through research grants and through sponsored meetings that overcame disciplinary boundaries, bringing together scientists from diverse backgrounds. The presence of a handful of prominent senior scientists such as Joshua Lederberg, Melvin Calvin and Norman Horowitz helped gain credibility for exobiology, in the face of criticism and competition from existing life sciences disciplines. Tensions within the exobiology research community and between NASA-funded science and the academic research community are explored, as are such milestones of discipline formation as journals and professional societies.

What are cells? How are they related to each other and to the organism as a whole? These questions have exercised biology since Schleiden and Schwann (1838–1839) first proposed cells as the key units of structure and function of all living things. But how do we try to understand them? Through new technologies like the achromatic microscope and the electron microscope. But just as importantly, through the metaphors our culture has made available to biologists in different periods and places. These (...) two new volumes provide interesting history and philosophy of the development of cell biology. Reynolds surveys the field's changing conceptual structure by examining the varied panoply of changing metaphors used to conceptualize and explain cells – from cells as empty boxes, as building blocks, to individual organisms, to chemical factories, and through many succeeding metaphors up to one with great currency today: cells as social creatures in communication with others in their community. There is some of this approach in theVisionsedited collection as well. But this collection also includes rich material on the technologies used to visualize cells and their dialectical relationship with the epistemology of the emerging distinct discipline of cell biology. This volume centres on, but is not limited to, ‘reflections inspired by [E.V.] Cowdry's [1924 volume]General Cytology’; it benefits from a conference on the Cowdry volume as well as a 2011 Marine Biological Lab/Arizona State University workshop on the history of cell biology.

The purpose of the present paper is to formulate and resolve a certain puzzle surrounding God's existence and the standard attributes traditionally assigned to God.

In a recent symposium on Descartes' ontological argument, Norman Malcolm has restated a rather ingenious version of St Anse1m's ontological argument. 1 The purpose of the present paper is to assess the merits of this particular version of the ontological argument.

In 2012, a U.S. Institute of Medicine report called for a different approach to health care: “Left unchanged, health care will continue to underperform; cause unnecessary harm; and strain national, state, and family budgets.” The answer, they suggested, would be a “continuously learning” health system. Ethicists and researchers urged the creation of “learning health organizations” that would integrate knowledge from patient‐care data to continuously improve the quality of care. Our experience with an ongoing research study on atrial fibrillation—a trial known (...) as IMPACT‐AFib—gave us some insight into one of the challenges that will have to be dealt with in creating these organizations. Although the proposed educational intervention study placed no restrictions on what providers and health plans could do, the oversight team argued that the ethical principle of beneficence did not allow the researchers to be “bystanders” in relation to a control group receiving suboptimal care. In response, the researchers designed a “workaround” that allowed the project to go forward. We believe the experience suggests that what we call “bystander ethics” will create challenges for the kinds of quality improvement research that LHOs are designed to do. (shrink)

The contribution of this work is a classification of corporate social action underlying the Social Ratings Data compiled by Kinder Lydenburg Domini Analytics, Inc. We compare extant typologies of corporate social action to the results of our exploratory factor analysis. Our findings indicate four distinct latent constructs that bear resemblance to concepts discussed in prior literature. Akey finding of our research is that positive and negative social action are both empirically and conceptually distinct constructs and should not be combined in (...) future research. Additionally, we recommend that some prior research results be reconsidered to determine whether these newly derived measures might clarify some previous findings. (shrink)

Moral distress is a major problem for nurses, other clinicians, and the health system itself. But if properly understood and responded to, it is also a promising guide for healthcare improvement. When individuals experience moral distress or burnout, their reports must be seen as crucial data requiring careful attention to the individuals and to the organization. Distress and burnout will often point to important opportunities for system improvements, which may in turn reduce the experience of distress. For this potential virtuous (...) cycle to happen, individuals must be able to articulate their concerns without fear of retribution, and organizational leaders must be able to listen in an undefensive, improvementoriented manner.

Although leaders in the field of ethics have for many years pointed to the crucial role that organizations play in shaping healthcare ethics, organizational ethics remains a relatively undeveloped area of ethics activity. Clinical ethics committees are an important source of potential expertise, but new skills will be required. Clinical ethics committees seeking to extend their purview to organizational issues will have to respond to three challenges—how to gain sanction and support for addressing controversial and sensitive issues, how to develop (...) an acceptable process, and how to make a difference on the ground. The article presents practical suggestions for how clinical ethics committees meet these challenges. (shrink)

James E. Bruce explores the relationship between morality and God’s free choices in the thought of Francis Turretin. The first book-length treatment of Turretin’s natural law theory, Rights in the Law provides an important theological backdrop to Early Modern moral and political philosophy. Turretin affirms Thomas Aquinas’s approach to the natural law, calling it the common opinion of the Reformed orthodox, but he develops it, too, by introducing a threefold scheme of right —divine, natural, and positive—to explain how change (...) within the law is possible. For example, God can change the specific day for Sabbath observance from Saturday to Sunday—from positive right—without changing the natural law precept that finite creatures ought to rest. Yet even with respect to the natural law God is still free. God can make a world in which there is no such thing as murder: he can choose not to make a world that contains such a thing as man. What God cannot do is make a murderable man. So God’s free choices determine the natural law insofar as the natural law is constituted by the nature of the things that God has chosen to create.

It is shown that if ZF is consistent, then so is ZFC + GCH + "There is a graph with cardinality ℵ 2 and chromatic number ℵ 2 such that every subgraph of cardinality ≤ ℵ 1 has chromatic number ≤ ℵ 0 ". This partially answers a question of Erdos and Hajnal.

Abstract: This paper discusses global corporate citizenship in the twenty-first century. The primary focus is on the responsibility of management educators to foster among students an understanding of the causes and consequences of business activitiy that creates organizational wealth, including the role of stakeholders. The modern corporation is a stakeholder enterprise: stakeholders enable the business to create wealth and require that it distribute wealth appropriately. The stakeholder enterprise model, which has been so economically successful, also implies corporate citizenship responsibilities. The (...) Clarkson Principles are discussed as a means through which educators and managers can better understand and address the challenges of corporate citizenship in the modern world. (shrink)

While the prevalence of opioid use disorder among pregnant women has multiplied in the United States in the last decade, buprenorphine treatment for peripartum women with OUD has been administered to reduce risks of repeated cycles of craving and withdrawal. However, the maternal behavior and bonding in mothers with OUD may be altered as the underlying maternal behavior neurocircuit is opioid sensitive. In the regulation of rodent maternal behaviors such as licking and grooming, a series of opioid-sensitive brain regions are (...) functionally connected, including the ventral pallidum. In humans, these brain regions, interact with the supplementary motor area to regulate maternal behaviors and are functionally dysregulated by opioids. It is unclear how these brain regions respond to the emotions of their child for mothers receiving BT. In this functional magnetic resonance imaging pilot study in 22 mothers within the first postpartum year, including six mothers receiving BT and 16 non-OUD mothers as a comparison group, we devised a child face mirroring task in fMRI settings to assess maternal responses to pictures of facial expressions of own child and an unknown child in an empathic mirroring condition and a non-mirroring observation condition. In each condition, faces of neutral, ambiguous, distressed, and joyful expressions of each child were repeatedly displayed in a random order. The response of SMA during empathic mirroring vs. non-mirroring of own child was reduced among BT/OUD vs. CG. Within MBN, the left VP, critical for parental sensitivity, had a similar deficit. This study outlines potential mechanisms for investigating the risks of deficits in the neural responses to actual maternal sensitivity and parenting behavior in mothers with OUD, and potential targets for interventions that reduce stress and augment maternal behavior and child outcome.

Should mental health insurance cover only disorders found in DSM‐IV, or should it be extended to treatment for ordinary shyness, unhappiness, and other responses to life's hard knocks?

Several canonical partition theorems are obtained, including a simultaneous generalization of Neumer's lemma and the Erdos-Rado theorem. The canonical partition relation for infinite cardinals is completely determined, answering a question of Erdos and Rado. Counterexamples are given showing that in several ways these results cannot be improved.

The Alexandrian emphasis on smallness, elegance, and slightness at the expense of grand themes in major poetic genres was not preciosity for its own sake: although the poetry was written by and for scholars, it had much larger sources than the bibliothecal context in which it was composed. Since the time of the classical poets, much had changed. Earlier Greek poetry was an intimate part of the life of the city-state, written for its religious occasions and performed by its citizens. (...) But eh conquests of Alexander had altered the structure and the boundaries of the Greek world to an astonishing degree. Alexandria, the center of the poetic culture of the new age, was a city that had not even existed at the time of Euripides; it was in Egypt, not in Greece, and was a huge, polyglot community. As immigrants immersed in a new, impersonal, and bureaucratic society, the poets not unreasonably sought out what was small, intimate, and personal in their verses. The heroes of early Greek poetry are larger than life; those of Alexandrian poetry are life-size. They are human, like us; they have a childhood and an old age; they are afraid or in love or caught in a rainstorm. It was simply one way of reducing the world to more manageable dimensions. At the same time, the new world of Alexandria needed a new poetry. To continue writing epics about a mythology that seemed very far away was senseless; it was impossible to recapture either the style or the immediacy of Homer, lyric poetry, or Attic tragedy. The scholar-poets of Alexandria admired the literature of classical Greece; for them Homer was incomparable and inimitable, to be studied—but not to be copied. Far better, then, to find a new voice on a more manageable scale: instead of oral epic, erudite epyllion; instead of lyric, epigram; instead of tragedy, mime. The poets of an urban and unheroic world might long for but could never re-create the grandeur of the past. James E. G. Zetzel is associate professor of classics at Princeton University and editor of the Transactions of the American Philological Association.

If the death of Jesus is nothing less than God's Christ hanging on a cross, we cannot speak about God—and ourselves—in any customary way. How do we preach this word of the cross as the word of life? Our answer points toward an apocalyptic homiletic.
