The statistical characterisation and synthetic reproduction of a polycrystalline material's microstructure is assisted by mathematically representing its morphology by a tessellation model. The generalised balanced power diagram (GBPD) is a tessellation model that was shown in previous studies to accurately reproduce the microstructure morphology of various materials by closely matching micrographs obtained through electron microscopy. These studies employed costly optimisation procedures to determine the best-fit model parameters, limiting the scalability of the model. In this work, it is shown that setting the tessellation cell parameters to values such that the shape moments of the corresponding grains are matched results in a quality of fit that is commensurate with optimisation procedures. This fitting approach decouples the interaction among grains when fitting the tessellation parameters and, most notably, provides analytical, closed-form expressions for all the model parameters. The performance of this parameter fitting approach is demonstrated on multiple micrographs of various materials, and it compares similarly to the performance of optimisation procedures reported in recently published literature. As the fitted parameter values are obtained through trivial computations, this approach enables extensive scalability of the GBPD model such that it can be used to represent extremely large characterisation data sets.  相似文献

In newly formed groups, informal hierarchies emerge automatically and readily. In this study, we argue that emergent group hierarchies enhance group performance (Hypothesis 1) and we assume that the more the power hierarchy within a group corresponds to the task‐competence differences of the individual group members, the better the group performs (Hypothesis 2). Twelve three‐person groups and 28 four‐person groups were investigated while solving the Winter Survival Task. Results show that emerging power hierarchies positively impact group performance but the alignment between task‐competence and power hierarchy did not affect group performance. Thus, emergent power hierarchies are beneficial for group performance and although they were on average created around individual group members' competence, this correspondence was not a prerequisite for better group performance.  相似文献

This study examines the work experiences of domestic workers in the context of socio-economic-political legislation promulgated to protect their social rights in the new South Africa. It gains insight into the power relations and embedded tensions between employers and domestic workers with the aim of identifying forms of oppression affecting domestic workers. In-depth interviews were conducted with nine female domestic workers employed in African households and analyzed using thematic content analysis. Results indicate that despite inclusion in labour legislation, domestic workers remain a vulnerable group. They experience oppression in the form of exploitation, marginalization, powerlessness, violence and some class-based cultural imperialism. Despite this, agency and resistance in the face of oppression was a key finding. Although some gains may have been obtained through inclusion in legislation, the asymmetrical power relationship with employers remains problematic.  相似文献

ABSTRACT

The philosophical-psychological Lvov-Warsaw School, derived from the philosophical tradition of Franz Brentano, developed his concept of intentionality for many years in an original way. This is particularly evident in Kazimierz Twardowski’s theory of actions and products and Tadeusz Tomaszewski’s theory of action. Kazimierz Ajdukiewicz’s semantic epistemology is also an important yet unfinished achievement (though less related to the issue of intentionality), in the light of which cognitive processes are organically embedded in cultural artefacts and, more specifically, in language. Despite the extraordinary wealth of the Lvov-Warsaw School’s achievements, the theoretical findings of Twardowski and his disciples allow for the extraction of relatively consistent conclusions regarding the specifics of human cognition. Achievements of the Polish school of psychology seem to be important in the long ongoing discussion on the topic of the nature of cognitive processes and the mind.  相似文献

Power and organizational hierarchies are ubiquitous to social institutions that form the foundation of modern society. Power differentials may act to constrain or enhance people’s ability to make good ethical decisions. However, little scholarly work has examined perceptions of this important topic. The present effort seeks to address this issue by interviewing academics about hypothetical ethical problems that involve power differences among those involved. Academics discussed what they would do in these scenarios, often drawing on their own experiences. Using a think-aloud protocol, participants were prompted to discuss their reasoning and thinking behind their ethical decisions. These interview data were content analyzed using a semantic analysis program that identified a number of distinct ways that academics think about power differences and abuses in ethical situations. Implications of these findings are discussed.  相似文献

Creativity is an important component of human intelligence, and imbuing artificially intelligent systems with creativity is an interesting challenge. In particular, it is difficult to quantify (or even qualify) creativity. Recently, it has been suggested that conditions for attributing creativity to a system include: appreciation, imagination, and skill. We demonstrate and describe an original computer system (called DARCI) that is designed to produce images through creative means. We present methods for evaluating DARCI and other artificially creative systems with respect to appreciation, imagination, and skill, and use these methods to show that DARCI is arguably a creative system.  相似文献

Abstract

This comparison study examined the relation between presumed level of exposure to the accident at Chernobyl in 1986 to symptoms of post-traumatic stress disorder (PTSD) and other psychological symptoms (depression, somatization, anxiety, obsessive-compulsive style and interpersonal sensitivity), life events and the negative appraisal of the events surrounding the accident. The sample (N = 708) included new immigrants from the former Soviet Union (Confederation of Independent States) who arrived in Israel since 1989 from more exposed areas (n = 137), less exposed (n = 240) and a comparison sample (n = 331) who immigrated from other republics. The exposed groups had higher mean scores on all psychological outcome measures than the comparison group, particularly symptoms of PTSD. Both subsequent stressful life events and a negative, cognitive assessment of events contributed to present psychological distress, independent of exposure.  相似文献

The neoliberal regime has significant consequences for the psychotherapies. In particular, the idea that individuals is deserving of support from society and government when they need it – for example in managing the inevitable stresses of the life cycle – is being displaced by an ideology of total individual responsibility. Psychotherapies framed around relational conceptions of the self find themselves particularly out of key with this dominant way of thinking. Governmental approaches to developmental needs become more instrumental, measurement-oriented and ‘disciplinary’ in this situation. Market incentives and disciplinary sanctions are introduced to ensure that institutions and their personnel conform to governmental directives. There is pressure on psychotherapists to adapt to this instrumentalised environment to survive. However, ‘expressive individualisation’ was also stimulated by the cultural liberation of the 1960s, and survives alongside the ‘possessive individualism’ of neoliberalism. This alternative culture has not been entirely suppressed, and therapies continue to be sought which offer the possibility of self-understanding and growth, although the pressure is for such therapies to become luxury goods. What is at risk under neoliberalism is the idea that society should support the self-development and self-understanding of all its citizens, as an aspect of a modern kind of democratic citizenship.  相似文献

Previous research suggests that there is a relationship between social contexts (e.g., economic growth, engagement in wars) and motives within populations. In particular, high achievement motive is associated with subsequent economic growth, which in turn increases power motive. Increased national achievement and power motives have been argued to precede social changes that lead to decreased affiliation motives, and engagement in wars. The present study aimed to examine differences in achievement, power, and affiliation motives between 266 college students in China (a nation with sustained high economic growth) and 255 college students in the USA (a nation with previously strong but now slowing economic growth, and engaged in war). Analysis of personal strivings suggested that Chinese college students showed significantly higher levels of achievement motive than the American college students, but American college students showed significantly higher levels of affiliation motive than Chinese college students. Overall, males exhibited higher achievement motivation than females. No significant interaction effects were found for gender by location for any of the three motives. The findings are discussed in relation to previous research.  相似文献
