High self-esteem predicts personal resilience but also predicts zealous and antisocial reactions to various threats, such as, failure, uncertainty, and mortality salience. The present research supports a basic motivational interpretation of high self-esteem that can account for its resilient but also its zealous and antisocial tendencies. An experimentally manipulated uncertainty threat caused participants with high self-esteem to react with heightened Relative Left Frontal (F7/F8) EEG Activity, a common neural marker of resilient approach-motivation. As predicted by past theorizing on offensive defensiveness (McGregor, 2006), the obtained pattern of neural results mirrors the interaction effect of self-esteem and threat on various antisocial defenses. It is accordingly suggested that reactive approach-motivation processes may help provide an integrative account for some of the angry, zealous, proud, risky, ideological, meaning-seeking, and worldview defense reactions to various threats that have been reported in the social psychological literature. 相似文献

Explicit solutions are obtained for a sequence of limiting distributions of response probabilities for the two experimenter-controlled events learning model of Bush and Mosteller [2]. A generalization to thes experimenter-controlled events model is found. 相似文献

A longitudinal study tested the self-determination theory (SDT) process model of health behavior change for glycemic control within a randomized trial of patient activation versus passive education. Glycosylated hemoglobin for patients with Type 2 diabetes (n=159) was assessed at baseline, 6 months, and 12 months. Autonomous motivation and perceived competence were assessed at baseline and 6 months, and the autonomy supportiveness of clinical practitioners was assessed at 3 months. Perceptions of autonomy and competence were promoted by perceived autonomy support, and changes in perceptions of autonomy and competence, in turn, predicted change in glycemic control. Self-management behaviors mediated the relation between change in perceived competence and change in glycemic control. The self-determination process model fit the data well. 相似文献

This article tenders an inaugural discussion of how conceptual change theory can contribute to deeper understandings of what is conceptually involved when people attempt (or succeed) to transition from multi- and interdisciplinarity to transdisciplinarity. After explaining the nuances of Newtonian thinking (framed as formal rather than postformal thinking), the article shares a comparison of multi-, inter-, and transdisciplinarity along four dimensions. Special attention is given to Nicolescuian transdisciplinarity, an approach predicated on the new sciences of quantum physics, chaos theory, and living systems theory (rather than Newtonian and Cartesian thinking). Nicolescuian transdisciplinarity is a new methodology for creating knowledge and it comprises three axioms: multiple Levels of Reality and the Hidden Third; the Logic of the Inclusive Middle; and, knowledge as complex, emergent, and embodied. The discussion then turns to an overview of three basic approaches to conceptual change theory: knowledge as theory, knowledge as elements, and knowledge as context. The author then applies conceptual change theory to understand what is involved in moving toward transdisciplinary thinking, including four elements necessary for conceptual change to occur (intelligibility, plausibility, fruitfulness, and dissatisfaction with existing conceptualizations and mental models). The article concludes with the idea that transdisciplinary thinking is a form of postformal thinking (especially paradigmatic order thinking) and suggests that future conceptual shifts toward transdisciplinarity involve achieving a transdisciplinary conceptual tipping point. 相似文献

The left ventricular assist device was originally designed to be surgically implanted as a bridge to transplantation for patients
with chronic end-stage heart failure. On the basis of the REMATCH trial, the US Food and Drug Administration and the US Centers
for Medicare & Medicaid Services approved permanent implantation of the left ventricular assist device as a destination therapy
in Medicare beneficiaries who are not candidates for heart transplantation. The use of the left ventricular assist device
as a destination therapy raises certain ethical challenges. Left ventricular assist devices can prolong the survival of average
recipients compared with optimal medical management of chronic end-stage heart failure. However, the overall quality of life
can be adversely affected in some recipients because of serious infections, neurologic complications, and device malfunction.
Left ventricular assist devices alter end-of-life trajectories. The caregivers of recipients may experience significant burden
(e.g., poor physical health, depression, anxiety, and posttraumatic stress disorder) from destination therapy with left ventricular
assist devices. There are also social and financial ramifications for recipients and their families. We advocate early utilization
of a palliative care approach and outline prerequisite conditions so that consenting for the use of a left ventricular assist
device as a destination therapy is a well informed process. These conditions include: (1) direct participation of a multidisciplinary
care team, including palliative care specialists, (2) a concise plan of care for anticipated device-related complications,
(3) careful surveillance and counseling for caregiver burden, (4) advance-care planning for anticipated end-of-life trajectories
and timing of device deactivation, and (5) a plan to address the long-term financial burden on patients, families, and caregivers. 相似文献
