M. H. Bond (2002) (see record 2002-00183-002), A. P. Fiske (2002) (see record 2002-00183-003), S. Kitayama (2002) (see record 2002-00183-004), and J. G. Miller (2002) (see record 2002-00183-005) joined D. Oyserman, H. M. Coon, and M. Kemmelmeier (2002) (see record 2002-00183-001) in highlighting limitations of the individualism-collectivism model of culture. Concern is warranted; nevertheless, individualism-collectivism helps structure discourse on the influence of culture on the mind. To avoid level-of-analysis entanglements, Oyserman et al propose an integrative model that includes distal, proximal, and situated cultural features of societies and internalized models of these features, highlights the importance of subjective construal, and uses evolutionary perspectives to clarify the basic problems cultures address. Framed this way, it is clear that, depending on situational requirements, both individualism- and collectivism-focused strategies are adaptive; thus, it is likely that human minds have adapted to think both ways.

This paper describes several low‐cost methods for fabricating flexible electronic circuits on paper. The circuits comprise i) metallic wires (e.g., tin or zinc) that are deposited on the substrate by evaporation, sputtering, or airbrushing, and ii) discrete surface‐mountable electronic components that are fastened with conductive adhesive directly to the wires. These electronic circuits—like conventional printed circuit boards—can be produced with electronic components that connect on both sides of the substrate. Unlike printed circuit boards made from fiberglass, ceramics, or polyimides, however, paper can be folded and creased (repeatedly), shaped to form three‐dimensional structures, trimmed using scissors, used to wick fluids (e.g., for microfluidic applications) and disposed of by incineration. Paper‐based electronic circuits are thin and lightweight; they should be useful for applications in consumer electronics and packaging, for disposable systems for uses in the military and homeland security, for applications in medical sensing or low‐cost portable diagnostics, for paper‐based microelectromechanical systems, and for applications involving textiles. 相似文献

Melting temperatures of zirconium carbide were investigated in validating a novel thermal analysis technique for refractory materials. Commercial ZrC0.96 powder was densified by spark plasma sintering to >96% relative density after 6–30 min at 2173–2453 K under 40–100 MPa. Sintered ceramics were heated to >4000 K via pulsed laser heating. Mean values for solidus and liquidus transitions were 3451 and 3608 K, respectively, in fair agreement with the present phase diagram. Postmelting analysis revealed dendritic microstructure and composition consistent with single-phase ZrC. Subsurface gas porosity and ZrC–C eutectic indicate complex processes occurring during melting and freezing. 相似文献

Erythropoietin (EPO) regulation of red blood cell production and its induction at reduced oxygen tension provides for the important erythropoietic response to ischemic stress. The cloning and production of recombinant human EPO has led to its clinical use in patients with anemia for two and half decades and has facilitated studies of EPO action. Reports of animal and cell models of ischemic stress in vitro and injury suggest potential EPO benefit beyond red blood cell production including vascular endothelial response to increase nitric oxide production, which facilitates oxygen delivery to brain, heart and other non-hematopoietic tissues. This review discusses these and other reports of EPO action beyond red blood cell production, including EPO response affecting metabolism and obesity in animal models. Observations of EPO activity in cell and animal model systems, including mice with tissue specific deletion of EPO receptor (EpoR), suggest the potential for EPO response in metabolism and disease. 相似文献

Longitudinal stability of temperamental exuberance and social–emotional outcomes in early childhood.
Degnan Kathryn A.; Hane Amie Ashley; Henderson Heather A.; Moas Olga Lydia; Reeb-Sutherland Bethany C.; Fox Nathan A. 《Canadian Metallurgical Quarterly》2011,47(3):765
The goals of the current study were to investigate the stability of temperamental exuberance across infancy and toddlerhood and to examine the associations between exuberance and social–emotional outcomes in early childhood. The sample consisted of 291 4-month-olds followed at 9, 24, and 36 months and again at 5 years of age. Behavioral measures of exuberance were collected at 9, 24, and 36 months. At 36 months, frontal electroencephalogram (EEG) asymmetry was assessed. At 5 years, maternal reports of temperament and behavior problems were collected, as were observational measures of social behavior during an interaction with an unfamiliar peer in the laboratory. Latent profile analysis revealed a high, stable exuberance profile that was associated with greater ratings of 5-year externalizing behavior and surgency, as well as observed disruptive behavior and social competence with unfamiliar peers. These associations were particularly true for children who displayed left frontal EEG asymmetry. Multiple factors supported an approach bias for exuberant temperament but did not differentiate between adaptive and maladaptive social–emotional outcomes at 5 years of age.

Although incivility has been identified as an important issue in workplaces, little research has focused on reducing incivility and improving employee outcomes. Health care workers (N = 1,173, Time 1; N = 907, Time 2) working in 41 units completed a survey of social relationships, burnout, turnover intention, attitudes, and management trust before and after a 6-month intervention, CREW (Civility, Respect, and Engagement at Work). Most measures significantly improved for the 8 intervention units, and these improvements were significantly greater than changes in the 33 contrast units. Specifically, significant interactions indicating greater improvements in the intervention groups than in the contrast groups were found for coworker civility, supervisor incivility, respect, cynicism, job satisfaction, management trust, and absences. Improvements in civility mediated improvements in attitudes. The results suggest that this employee-based civility intervention can improve collegiality and enhance health care provider outcomes.

Food additives and substances considered “generally recognized as safe” must not be allowed in food unless there is a reasonable certainty in the minds of competent scientists that the substance is not harmful under the intended conditions of use. Scientists determine safety by ensuring that the expected exposure is less than the acceptable daily intake. The U.S. Food and Drug Administration (FDA) provides guidance documents to assist safety assessors in this analysis. A November 2011 workshop sponsored by The Pew Charitable Trusts, the Institute of Food Technologists, and the journal Nature reviewed the agency's exposure assessment approaches. More than 70 experts from government (including FDA), industry, academia, and public interest organizations examined the principles underlying dietary exposure assessments for substances added to human food, and responded to questions about current methods. FDA's approach was seen as serving the agency reasonably well, but participants identified opportunities for improvement. Although reaching a consensus was not a goal, general agreements emerged that FDA should develop a science‐based framework to prioritize and reassess prior safety decisions, and conduct more extensive postmarket monitoring. Participants discussed the possibility of harmonizing different approaches to assess dietary exposure. They generally agreed that collaboration, communication, and exchanging scientific information between agencies and stakeholders would help assessors use the most current information to make better decisions. Participants identified data gaps and opportunities to fill the gaps using new tools and technologies. Participants generally agreed on the need to consider all dietary sources in a cumulative dietary exposure assessment. 相似文献

The rise and 'fall' of expert systems in medicine 总被引:1,自引:0,他引:1
Heather Heathfield 《Expert Systems》1999,16(3):183-188
This paper represents a personal perspective on the last 13 years of research in medical artificial intelligence and expert systems, and describes the progress of the discipline from its inception to its current status. The challenges faced by researchers are examined, and it is argued that (despite the claims) theoretical and technical limitations are not the major barriers to the successful implementation of medical artificial intelligence and expert systems, but rather more complex professional and organizational issues are at stake. 相似文献
