Systems biology is the rapidly growing and heavily funded successor science to genomics. Its mission is to integrate extensive bodies of molecular data into a detailed mathematical understanding of all life processes, with an ultimate view to their prediction and control. Despite its high profile and widespread practice, there has so far been almost no bioethical attention paid to systems biology and its potential social consequences. We outline some of systems biology's most important socioethical issues by contrasting the concept of systems as dynamic processes against the common static interpretation of genomes. New issues arise around systems biology's capacities for in silico testing, changing cultural understandings of life, synthetic biology, and commercialization. We advocate an interdisciplinary and interactive approach that integrates social and philosophical analysis and engages closely with the science. Overall, we argue that systems biology socioethics could stimulate new ways of thinking about socioethical studies of life sciences.  相似文献

SUMMARY

The majority of gay male couples are not monogamous. Relationship clinicians can help gay male couples to have a healthy sexually open relationship by working from a family systems perspective. This approach requires the therapist to have an understanding of family systems theory, the Enneagram (a personality topology), gay male sexual culture, as well as being clear of negative countertransference. Assessment of functionality of sexually open gay male relationships is described.  相似文献

ABSTRACT

This article traces how managed care became a quick fix to curb out-of-control healthcare costs rather than a real effective approach to managing care. To date, the impact has been not only a negative experience, but impediment to treating couples facing relationship and related problems. The author is optimistic about how managed care will evolve to recognize the importance of couples and family treatment as we enter the future with integrated systems of healthcare. ? The future will also require significant shifts in the thinking and practice patterns of providers and an emphasis on quality and outcomes.  相似文献

In 2 experiments, dynamic systems theory predictions concerning intrinsic dynamics and variability of bimanual coordination were examined at different developmental stages. In Experiment 1, ten 4-, 6-, 7-, 8-, and 10-year-old children and adults performed unimanual dominant, unimanual nondominant, and bimanual continuous circle drawing. All tasks were performed at the participants' preferred rate, size, and mode of coordination. The 4-, 6-, and 7-year-old children produced larger circles with longer durations than those of the 8- and 10-year-olds and the adults. That finding demonstrates that younger children display different intrinsic dynamics than older children and adults. The 4-, 6-, and 7-year-old children also displayed more variability in bimanual coordination (more time in less stable patterns of coordination, higher standard deviation in relative phase) and produced more transitions between coordination patterns than the 8- and 10-year-olds and the adults. In Experiment 2, the same participants performed bimanual circles at increasing rates. Consistent with predictions of the HKB model (H. Haken, J. A. S. Kelso, & H. Bunz, 1985), the number of transitions decreased as speed increased. Some support was found for the notion that age-related variables of attention and rate contribute to the increased variability in young children's bimanual coordination.  相似文献

Abstract

Technological developments increasingly permit the collection of longitudinal data sets in which the data structure contains a large number of participants N and a large number of measurement occasions T. Promising new dynamical systems approaches to the analysis of large N, large T data sets have been proposed that utilize both between-subjects and within-subjects information. The COGITO project, begun over a decade ago, is an early large N?=?204, large T?=?100 study that collected high quality cognitive and psychosocial data. In this introduction, I describe the COGITO project and conceptual and statistical issues that arise in the analysis of large N, large T data sets. I provide a brief overview of the five papers in the special section which include conceptual pieces, a didactic presentation of a dynamic structural equation approach, and papers reporting new statistical analyses of the COGITO data set to answer substantive questions. Although many challenges remain, these new approaches offer the promise of improving scientific inquiry in the behavioral sciences.  相似文献

Summary

This article provides a brief reflection on how the Change of Seasons treatment model developed and the reasons for its success with Aboriginal men. Parallels between Aboriginal perspectives, or worldviews, and Ken Wilber's transpersonal psychology, Rupert Sheldrake's fields theory, and Peter Senge's systems thinking are also discussed. Practical rituals and ceremonies that have been successfully integrated into psychoeducational group counselling as practiced in the Change of Seasons model are explained. These musings are included to initiate further dialogue on holistic approaches to counselling and other community initiatives.  相似文献

The prevalence of trauma and its negative impact on humankind have created a burgeoning awareness of the need for systems that are trauma-informed across the lifespan. A collaborative project with the National Partnership to End Interpersonal Violence (NPEIV) sought out research as a call-to-action to mitigate the impact of trauma. The following is Part II of an introduction to a special double-issue focused on theoretical and applied approaches to using trauma-informed care in multi-disciplinary, mental and physical health, criminal justice, school-based, and community settings. Consideration is given to essential issues such as resilience, self-care, and intersectional cultural awareness. Introspective exploration of biases was encouraged to address barriers to implementing trauma-informed care.  相似文献

Sixty-seven United States Navy maintainers (55 men and 12 women) representing both the aviation and surface communities participated in an experiment examining the efficacy of a simulation to assist technicians in rapidly understanding a system's state. Participants were assigned to one of three groups based on the technicians' experience and one of two experimental conditions: simulation (SIM) or technical manual (TM). The experimental task consisted of a series of eight questions regarding the condition of the S-3 aircraft's nose wheel steering (NWS) system given a set of initial aircraft conditions. To aid in performance of the experimental task, participants assigned to the TM condition were given a paper copy of the S-3 aircraft's organizational maintenance manual for the NWS system, and participants assigned to the SIM condition were given a laptop computer running a computer-based interactive model of the S-3 NWS system. Results showed that regardless of level of expertise, participants assigned to the SIM condition answered questions significantly faster than participants assigned to the TM condition. Further, technicians experienced in nonaviation maintenance assigned to the SIM condition answered questions significantly more accurately than experienced nonaviation technicians assigned to the TM condition.  相似文献

The paper reviews central concepts and research findings of attachment theory emphasizing its clinical relevance to psychoanalytically informed clinicians. We then turn to a historical analysis in order to understand why Bowlby's work was dismissed within psychoanalytic circles and the reasons why Bowlby's contributions and attachment theory have begun to have a significant impact among clinicians within the last ten years.  相似文献

This article combines a constructivist grounded theory approach with a focus on structuration theory to propose a new mental model for understanding motivation in the context of solving complex problems in contemporary business-to-business (B2B) settings. This study uses the interpretative tradition of qualitative research to conduct in-depth interviews of 24 B2B sales professionals and subsequently analyze their lived experiences. Findings indicate that intrinsic motivation stems attitudinally from a need to foster an identity of helping customers, introducing a concept called “interpersonal identification” with customers. That identity motivates the development of more cognitively intense sales proposals using a more holistic proposal development process – referred to herein as “systems-savvy selling.” While interpersonal relationships have long been components of B2B relationships, this study challenges laypeople’s stereotypes of salespeople who use interpersonal relationships to improve business outcomes. Instead, systems-savvy selling helps salespeople build interpersonal relationships and use business outcomes as feedback to strengthen interpersonal relationships and their identification with customers. Unexpectedly, it also finds that dual-role sales managers, who have roles both in selling and managing, confront a paradox of self versus others when managing systems-savvy selling processes. By sampling within an industry in which the research team benefits from significant expertise, the constructivist grounded theory approach relying on semistructured, in-depth interviews used herein leverages the research team’s expertise while controlling for industry-level effects.  相似文献
