Development of the vertebrate pancreas is a complex stepwise process comprising regionalization, cell differentiation, and morphogenesis. Studies in zebrafish are contributing to an emerging picture of pancreas development in which extrinsic signaling molecules influence intrinsic transcriptional programs to allow ultimate differentiation of specific pancreatic cell types. Zebrafish experiments have revealed roles for several signaling molecules in aspects of this process; for example our own work has shown that retinoic acid signals specify the pre‐pancreatic endoderm. Time‐lapse imaging of live zebrafish embryos (...) has started to provide detailed information about early pancreas morphogenesis. In addition to modeling embryonic development, the zebrafish has recently been used as a model for pancreas regeneration studies. Here, we review the significant progress in these areas and consider the future potential of zebrafish as a diabetes research model. (shrink)

In this paper, we look at the new frontier of e-commerce, the ethical challenges it is facing and discuss some of the problems encountered and some of the solutions that are evolving. The areas of concern include the impact on other businesses, investors and consumers. Problems regarding financial reporting, intellectual property and privacy are discussed.

In this exploratory study, we look at the professed values that people have, and their performance in a negotiation. We found relations between Schwartz values and conflict handling behaviors, and distributive, integrative, and compatible negotiation outcomes in a controlled environment using Actor-Partner Interdependence Model (APIM) analysis.

Covering popular, historical, scientific, and cultural aspects of death and the hereafter, The Afterlife Book tackles the big questions of death and dying-and life. It looks for objective answers but often comes away with subjective answers, both well-reasoned and profound. It looks at the natural cycles of birth, life, death, and (possibly) rebirth. This engrossing book looks at death rituals across the globe and the many competing views of the afterlife-and the shared connections between them. Includes an extensive appendix of (...) testimonials by people who have had afterlife experiences. (shrink)

Clerical frames for nursing practice: missionary nurses at Rehoboth This paper presents a discourse analysis of publications of the Christian Reformed Church regarding its Rehoboth Mission near Gallup, New Mexico, among the Navajo. All issues of The Banner, Acts of Synod of the Christian Reformed Church, the Rehoboth Hospital Bulletin, and the Annual Report of the Rehoboth Mission from 1880 to the present were reviewed for references to health‐care at Rehoboth from 1903 to 1943. Four religiously framed discourses were identified: (...) discourses justifying provision of health‐care at the mission, discourses of the Navajos as immature and potentially dangerous, needing to be civilized, discourses of cleanliness, and discourses of calling. This paper adds to a growing body of knowledge about religious frames within which nurses have practiced in North America. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Incorporating Religion into Psychiatry:Evidenced–Based Practice, Not a Bioethical DilemmaMary D. MollerFor over sixteen years I was the owner and clinical director of an advanced practice nurse–managed outpatient rural psychiatric clinic staffed by APNs, a social worker, a licensed counselor and several graduate students. Many of our patients were victims of severe and often brutal trauma and abuse suffered at the hands of family, friends, and various professionals including spiritual (...) leaders. We also uncovered sources of abuse suffered from those involved in occult practices ranging from seemingly innocent white witchcraft (Wicca, Paganism, New Age) that includes such activities as astral projection and remote viewing to the darkest possible black witchcraft (perpetrating evil, incanting evil spirits, casting spells and hexes, creating dissociative identities) such as occurs in ritual abuse and satanic rites. Both types of witchcraft also typically involved family, friends, various professionals, and spiritual leaders. Recognizing the controversy surrounding the reality of witchcraft I am sharing a story that I hope will help break down the barriers that prevent many patients from receiving the treatment that would provide the most benefit to recovery.Seeking services for these patients led me on an intense personal and professional journey that included a profound Christian born–again experience at almost 50 years of age. My professional career grew in nearly indescribable terms as a result of the incorporation of prayer and deliverance ministry as part of the services we selectively provided. Today I always include assessment of spiritual experiences a patient has as well as spiritual supports that are available with every new patient intake. For patients who indicate that prayer is one of their supports, I ask if they would like prayer at the conclusion of the session. The gratitude that is expressed by individuals who appreciate being able to pray with a psychiatric provider is often profound.In the field of psychiatry there has been a long–standing and distinct taboo regarding incorporating religious and spiritual aspects of life experience into treatment unless it is to frame most of these discussions within the context of psychosis. This stems from the advent of psychoanalysis in which religion was deemed a neurosis and atheism became the goal. Some still hold to that belief and there certainly remains controversy regarding the incorporation of prayer into routine outpatient or inpatient care. The essential starting point is the determination of accurate differential diagnosis, which can often be a lengthy process. The clinician must be careful about distinguishing between religious experiences and religious delusions, and often this takes time to sort out. The determination of the etiology of hearing the voice of God or the devil or demons must be carefully parsed and framed within the context of the situation and culture the patient describes. If the clinician denies the existence of God or the devil or demons or the practice of witchcraft, the patient’s descriptions of such experiences will be quickly [End Page 206] labeled psychotic. The patient may then experience a lengthy hospitalization and treatment with psychotropic medications that can have an extremely negative effect on the possibility of recovery. Once I witnessed the level of healing that occurs with carefully administered spiritual interventions that are related to specific spiritual experiences that are based on the patient’s belief system, there was no going back to using only allopathic medication and non–spiritual psychosocial interventions, even in spite of the criticisms from others. The key is to understand and respect the patient’s belief system, if this is not congruent with the practitioner’s belief system, then practitioner must refer out.In the United States, an increasing persecution of Christianity and a devaluing of the Judeo–Christian heritage of our Constitution are creating a climate of intolerance to the expression of religious values resulting in an expectation that Christians should compromise their beliefs for the sake of political correctness. As a doctorally prepared psychiatric–mental health advanced practice nurse I experienced a profound born–again Christian experience that ultimately led to study of the Hebrew roots of Christianity and I now worship in a Messianic Jewish synagogue. It is impossible for me to not include the concept of spirituality into... (shrink)

In their own words: nurses’ discourses of cleanliness from the Rehoboth Mission For nurses of the nineteenth and early twentieth centuries, cleanliness was often seen as a virtue next to godliness. For missionary nurses, this analogy took on multiple meanings. This study focuses on discourses of cleanliness at one site of missionary nursing in the early twentieth century: the Rehoboth Mission and its hospital, which provided health‐care to the Navajo in the southwestern USA from 1903 to 1965. Data sources included (...) denominational publications, institutional records, correspondence, questionnaires and interviews of the Dutch–American missionary nurses who practiced at the Rehoboth Mission. Discourse analysis was conducted on references to cleanliness, hygiene and sanitation in these texts. Secondary discourses of embodiment in daily practice, initiation and assimilation, caring, ignorance, environmental factors and gendered work were identified and analyzed. The study interrogates the whiteness of the nurses’ dominant culture and sheds light on nurses’ relationships with normative discursive frames that reflect and perpetuate inequalities, discredit non‐dominant practices, and leave little room for competing discourses. It also illustrates a blurring of religion and health‐care, and the need for a reflective and informed stance as a basis for cultural competence. (shrink)

Traditionally, certified public accountants (CPAs) have served a unique role in the world of commerce and the profession of accounting. They perform an attest function and thereby serve as the chief providers of relevant, high quality accounting information to the decision making public. CPAs are licensed practitioners, who as expert independent accountants express opinions about an entity'sfinancial statements. Their license provides them with the exclusive right to perform this attest function. This monoploy relies on the concept of independence that is (...) the normative standard of accountancy. It is this perceived independence of auditors which provides credibility, reliability and trust in the financial accounting information upon which stakeholders depend to make informed decisions. Now, however, we see the environment in which CPAs operate undergoing rapid change. Both the globalization of business operations and technological advances have radically changed how and where accountants work and the speed at which things happen. The very nature of accounting information services is evolving; moving from a concentration on audits to an increasing reliance on consulting and assurance services. New ethical issues have been raised by this confluence of changes in the accounting environment. Noteworthy is that the application of the principle of independence by CPAs has been called into question by no other than the SEC. Are those stakeholders who depend upon the independence of CPAs at risk? The influence of insiders has significantly increased as accounting firms perform multiple tasks for the same clients. This paper discusses the different groups who can potentially impair the independence of auditors and the steps that are being taken to enhance the "independence" of the auditors. (shrink)

Many have preached the need for business schools to "teach" ethics, but very few have considered that business schools should also adopt and implement their own codes. The authors' previous research indicates that there is a perceived need for a code of ethics for business schools. Currently, relatively few schools have in fact adopted codes of ethics applicable to all the constituents of the institution. Proposals made to businesses to help them determine which values should be included in a corporate (...) code do not appear to adequately address the distinctive issues faced in an academic environment. In an earlier survey, the authors identified general principles of conduct that seemed to encompass the values expressed by the respondents. Relying on research that has indicated that ideally a code of ethics should be inspirational and value oriented rather than prescriptive and proscriptive, the authors herein propose ten values and correlating definitions that would provide a framework for a business school code of ethics.

The aim of this exploratory study was to examine client demographics and expectations, reasons for use, sensations during treatment, and perceived outcomes of Pranic Healing, an energy healing system lacking in scientific documentation but whose use in the general population is becoming more widespread internationally. This study consisted of a cross-sectional survey of adults (18+ years of age) receiving care from 12 Pranic Healing practices in four different states in the U.S. (N = 179) completing online questionnaires. Closed-ended response sets (...) were analyzed descriptively, while qualitative data were analyzed using content analysis. Reasons to use the therapy included physical, mental/emotional, and metaphysical issues, dissatisfaction with conventional care, and overall well-being. Expectations of care included enhanced abilities, cure or relief, or unsure. Respondents were more likely to cite a specific problem from which they needed alleviation than to cite overall health or wellness as their goal. Sensations experienced were reported to be of a relaxing nature and not, as was hypothesized, of an energizing nature. Results show that those who use Pranic Healing fit the sociodemographic profile of CAM (complementary and alternative medicine) users in the United States, that their reasons for use are not homogeneous, and that preliminary descriptive data from a selective subsample of respondents indicated that some respondents are experiencing positive outcomes attributed to this modality.

In the years 1961-1972 Marie-Thirhse d'Alverny published in "Archives d'Histoire Doctrinale et Littiraire du Moyen Age 11 fascicles of a study of the codicological tradition of the Latin Avicenna. In these she identifies and describes more than 150 Latin manuscripts of the Avicennan corpus preserved in European libraries, thus laying the foundation for work later published in the "Avicenna Latinus series. These fascicles are photomechanically reprinted here, together with hitherto unpublished material concerning another 30 manuscripts compiled from Professor d'Alverny's papers (...) by Simone van Riet and Pierre Jodogne. The compilers have also added a list of corrigenda as well as an index of manuscripts discussed and an index of names and works. (shrink)

We hypothesize that effective collaboration is facilitated when individuals and environmental components form a synergy where they work together and regulate one another to produce stable patterns of behavior, or regularity, as well as adaptively reorganize to form new behaviors, or irregularity. We tested this hypothesis in a study with 32 triads who collaboratively solved a challenging visual computer programming task for 20 min following an introductory warm‐up phase. Multidimensional recurrence quantification analysis was used to examine fine‐grained (i.e., every 10 (...) s) collective patterns of regularity across team members' speech rate, body movement, and team interaction with the shared user interface. We found that teams exhibited significant patterns of regularity as compared to shuffled baselines, but there were no systematic trends in regularity across time. We also found that periods of regularity were associated with a reduction in overall behavior. Notably, the production of irregular behavior predicted expert‐coded metrics of collaborative activity, such as teams' ability to construct shared knowledge and effectively negotiate and coordinate execution of solutions, net of overall behavioral production and behavioral self‐similarity. Our findings support the theory that groups can interact to form interpersonal synergies and indicate that information about system‐level dynamics is a viable way to understand and predict effective collaborative processes.

What is the nature of mathematical knowledge? Is it anything like scientific knowledge or is it sui generis? How do we acquire it? Should we believe what mathematicians themselves tell us about it? Are mathematical concepts innate or acquired? Eight new essays offer answers to these and many other questions.

Objective Adolescents have had very limited access to research on biomedical prevention interventions despite high rates of HIV acquisition. One concern is that adolescents are a vulnerable population, and trials carry a possibility of harm, requiring investigators to take additional precautions. Of particular concern is preventive misconception, or the overestimation of personal protection that is afforded by enrolment in a prevention intervention trial. Methods As part of a larger study of preventive misconception in adolescent HIV vaccine trials, we interviewed 33 (...) male and female 16–19-year-olds who have sex with men. Participants underwent a simulated HIV vaccine trial consent process, and then completed a semistructured interview about their understanding and opinions related to enrolment in a HIV vaccine trial. A grounded theory analysis looked for shared concepts, and focused on the content and process of adolescent participants’ understanding of HIV vaccination and the components of preventive misconception, including experiment, placebo and randomisation. Results Across interviews, adolescents demonstrated active processing of information, in which they questioned the interviewer, verbally worked out their answers based upon information provided, and corrected themselves. We observed a wide variety of understanding of research concepts. While most understood experiment and placebo, fewer understood randomisation. All understood the need for safer sex even if they did not understand the more basic concepts. Conclusions Education about basic concepts related to clinical trials, time to absorb materials and assessment of understanding may be necessary in future biomedical prevention trials. (shrink)
