High-pressure structural stability studies have been carried out on tungsten boride W2B5 up to maximum pressure of 36 GPa using a Mao-Bell diamond-anvil cell at beamline BR-12 of the ELETTRA synchrotron facility (λ = 0.68881 Å). The hexagonal phase (S.G:P63/mmc) of W2B5 is stable up to the maximum pressure studied. The bulk modulus is estimated to be ~347 GPa using the Birch–Murnaghan equation of state. The variation of lattice parameters and bond lengths B–B and W–B have been studied and the c-axis is seen to be marginally more compressible than the a-axis. 相似文献

Treatment decision-making in chronic illness poses long-lasting effects on the health status of patients. In Western individualistic cultures, they are independently taken by the individual in collaboration with doctors contrary to the collectivistic Indian context, where it’s decided by families with little or no involvement of patients. Religious beliefs, patient–doctor interaction, and resilience measures of 100 CAD patients were used to assess their religious beliefs, patient–doctor interaction, and resilience (predictors). Hierarchical Regression Analysis was conducted to test for the significance of the proposed model. Religious beliefs, patient–doctor interaction, and resilience collectively predicted the significant change in decision-making styles, somatic symptoms, anxiety, social dysfunctions, depression, and general health total of the participants. While the treatment decision-making is heavily contingent upon the social factors namely – religious beliefs, patient–doctor interaction, and resilience, there may yet be some underlying psychological factors that have not been explored in the present study. 相似文献

Despite the potential for artificial intelligence (AI)-enabled technologies in healthcare, their benefits are limited owing to the numerous challenges of cognitive engagement. This research paper explores the factors of “cognitive engagement with AI-enabled technologies” and its impact on the customers' benefits and value creation. A mixed-method study was utilized in the Indian health-care setup where AI-based technology is developing. The qualitative findings shed light on the factors of cognitive engagement with AI-enabled technologies. Grounded on the theories of customer benefit, an integrative framework of customer-perceived financial, experiential, psychological, and functional benefits, alongside perceived instrumental and terminal values, was developed. The quantitative findings of PLS-SEM explain the dynamics of the patients' cognitive engagement with AI-enabled technologies. The results enrich a more nuanced understanding of how the patient benefits of AI applications have different impacts on perceived value. The study concludes with theoretical and practical implications. 相似文献

This is a review essay of Jeff McMahan's recent book The Ethics of Killing: Problems at the Margins of Life (OUP: 2002). In the first part, I lay out the central features of McMahan's account of the wrongness of killing and its implications
for when it is permissible to kill. In the second part of the essay, I argue that we ought not to accept McMahan's rejection
of species membership as having any bearing on whether it is permissible to kill a particular individual, as there are ways
of understanding its relevance that are more plausible than McMahan allows.

This article featuring India constitutes one of five articles in a collection of essays on local capacity-building in research
ethics by graduates from the University of Toronto’s Joint Centre for Bioethics MHSc in Bioethics, International Stream program
funded by the Fogarty International Center for Advanced Study in the Health Sciences. Research ethics is a growing area of
work and interest in India. Ethics review remains the weakest component in the mechanism of good clinical practice, and there
is a severe dearth of professionals trained in ethics who can provide leadership. Although the Indian Good Clinical Practice
Guidelines, the Indian Medical Council Act, and the Drugs and Cosmetics Act require that the Indian Council of Medical Research’s
ethical guidelines be followed as a mandatory requirement for physicians who conduct research, there is a pervasive lack of
awareness of basic requirements guiding the ethical conduct of research. There is a great need to strengthen India’s research
ethics capacity and regulatory framework for research. 相似文献

This study examined if task motivational imagery suggestions could facilitate a semantic priming effect, relative to general
relaxation suggestions and no specific suggestions; and if the participants’ hypnotizablity moderated the effects of the three
types of instructions. Participants (n = 127) were assigned randomly in groups to one of the three instructional conditions (imagery, relaxation, or control) and
two versions of a stimulus list for counterbalancing. A 3-way analysis of variance suggested that the semantic priming effect
was found to be stronger for stimulus list version 2 than for version 1. A stronger semantic priming effect was found for
the high, relative to the low and medium, hypnotizable groups. When medium hypnotizable participants were excluded, an instructional
group X hypnotizability group interaction was found for list 1 suggesting that while the low hypnotizable participants benefited
more from the relaxation suggestion, the high hypnotizables benefited more from the imagery instruction. The results suggest
that imagery instructions may moderate automatic processes for highly hypnotizable individuals. 相似文献

Many pluralistic nations are witnessing vigorous debate about multiculturalism. In the U.S., Americans generally embrace principles of ethnic diversity but dislike minorities who express strong ethnic identification. Two experiments examined this seeming contradiction by differentiating between ethnic identity expressed in private vs. public by non-White and White individuals. Then we tested whether individuals' identity expressions differentially affected perceivers' construal of their entire ethnic group as legitimately American. Results indicated that at a conscious level, White and non-White ethnic groups were held to the same standard and construed as significantly less American when members expressed their ethnic identity publicly vs. privately. However, at an unconscious level, a double standard emerged: non-White ethnic groups were implicitly rejected as less American if members expressed ethnic identity publicly, while White ethnics were implicitly accepted as legitimate Americans regardless of where they expressed ethnic identity. 相似文献

This study tested the notion that the construction and telling of a collaborative group story would facilitate the development of group cohesion within the context of an actual classroom setting over the duration of the course. Participants were 125 students in 8 classes (4 experimental, 4 control) of a group psychotherapy course that focused on the principles and techniques of cognitive behavior therapy in conjunction with psychodrama techniques. Results showed significantly higher cohesion scores in the experimental condition compared to the control condition, suggesting that collaborative story building and telling is a viable strategy for improving group cohesion. 相似文献

Based on longitudinal multilevel modeling and using a multi-informant strategy, this study examines trajectories of externalizing problem behavior (EPB) in childhood as predicted by parental behavior (absolute level of parenting [ALP] and parental differential treatment [PDT]), parental self-efficacy (PSE), child personality and sibling relationships. Besides main effects, several interactions were tested. The effects of changes in parenting on changes in EPB were also examined. A total of 119 families from the French-speaking area of Belgium rearing a child (3- to 5-year-olds at the onset of the study) referred for EPB were studied. The effects of both level-of and changes-in mothers' ALP were partially confirmed, but for fathers, only ALP was predictive. There were some significant interactions between ALP and PDT for both parents. Mothers' PSE explained some variance in EPB, additional to that explained by the parenting measures. Some parenting by personality and by sibling relationship interactions were found. 相似文献
