Status is a valued workplace resource that facilitates career success, yet little is known regarding whether and how cultural orientation affects status attainment. We integrate status characteristics theory with the literature on individualism and collectivism and propose a cultural patterning in the determinants of status. Four studies (= 379) demonstrate that cultural orientation influences the tendency to view high status individuals as competent versus warm (Study 1), uncover cultural differences in both individuals’ tendency to engage in competence and warmth behaviors to attain workplace status (Study 2) and evaluators’ tendency to ascribe status to individuals who demonstrate competence versus warmth (Study 3), and verify that cultural differences in the effects of competence and warmth on status perceptions, and in turn performance evaluations, generalize to real world interdependent groups (Study 4). Our findings advance theory on the cultural contingencies of status attainment and have implications for managing diversity at work.  相似文献

This paper explores the meaning of a patient's hallucinatory experiences in the course of a five times a week analysis. I will locate my understanding within the context of André Green's ideas on the role of the framing structure and the negative hallucination in the structuring of the mind. The understanding of the transference and countertransference was crucial in the creation of meaning and enabling the transformations that took place in the analytic process. Through a detailed analysis of a clinical example the author examines Bion's distinction between hysterical hallucinations and psychotic hallucinations and formulates her own hypothesis about the distinctions between the two. The paper suggests that whilst psychotic hallucinations express a conflict between life and death, in the hysterical hallucination it is between love and hate. The paper also contains some reflections on the dramatic nature of the analytic encounter.  相似文献

胰岛素研究的新突破   总被引:2,自引:0,他引:2  
人类与糖尿病抗争的历史最早可上溯到公元前1500年前,但直到20世纪20年代胰岛素才由生理学家FredrickBanting等发现。自此,挽救了数以百万计的糖尿病患者的生命。随后,人们在研究胰岛素如何调节物质代谢时,意外发现含胰岛素的激化液(Glucose-insulin-potassium,GIK)可改善急性心脏梗死患者的症状。提示,胰岛素还具有其它多方面的生理功能。近期研究证明,胰岛素确有抗心肌坏死与凋亡、进而保护缺血再灌注心肌的作用,这再次引起了人们对胰岛素进行深入研究的兴趣。从胰岛素的发现到对其新的作用机制的认识给我们带来许多有益的启示。  相似文献

If we study the behavior of organisms, we must understand the ontological status of both “organism” and “behavior.” A living organism maintains itself alive by constantly interacting with the environment, taking in energy and discarding waste. Ontologically, an organism is a process. Its interactions with the environment, which constitute its behavior, are processes also, because the parts of any process are themselves processes. Processes serve functions, and the function of a process must be part of its identity. A process, by definition, extends in time. Time is the fundamental and universal measure of behavior. All processes have the property of scale. Activities of an organism have parts that are themselves activities on a smaller time scale. Scale varies continuously, and behavior may be studied on as large or as small a time scale as seems necessary. When researchers refer to the “structure” of behavior, they refer to smaller-scale activities. Attaching a switch to a lever or key is convenient, but one should never confuse operation of a switch with a unit of behavior. Shimp's (2020) “molecular” measures are small-scale measures. The molecular view based on discrete events has outlived its usefulness and should be replaced by a multiscale molar paradigm.  相似文献

We propose a latent topic model with a Markov transition for process data, which consists of time-stamped events recorded in a log file. Such data are becoming more widely available in computer-based educational assessment with complex problem-solving items. The proposed model can be viewed as an extension of the hierarchical Bayesian topic model with a hidden Markov structure to accommodate the underlying evolution of an examinee's latent state. Using topic transition probabilities along with response times enables us to capture examinees' learning trajectories, making clustering/classification more efficient. A forward-backward variational expectation-maximization (FB-VEM) algorithm is developed to tackle the challenging computational problem. Useful theoretical properties are established under certain asymptotic regimes. The proposed method is applied to a complex problem-solving item in the 2012 version of the Programme for International Student Assessment (PISA).  相似文献

Integrated Project Delivery (IPD) has the potential to overcome inefficiencies of traditional delivery methods by enhancing collaboration among project participants, and is therefore gaining popularity in the Architecture, Engineering and Construction (AEC) industry. For owners considering an IPD approach and are incapable or unprepared to pursue a “pure” IPD project, an IPD-ish approach could be an alternative option. IPD mode is featured by implementing a range of fundamental principles. However, investigations on application of IPD-ish principles to actual construction projects are highly limited. This research mainly focused on a Cognitive Task Analysis (CTA) of the application of IPD principles to the design and construction of an IPD-ish project, and presenting a case study on an underground campus-parking facility. A case study for CTA was designed in this study: a project progress map was developed, wherein seven project phases were defined; by analyzing the project goals and technical measures in each project phase, six key IPD elements was summarized, and a few specific work measures for addressing these elements were discussed. For owners or participants intending to plan an IPD-ish project, the results of the study provide a few references on the selection and application of IPD principles in each project phase.  相似文献

表象、知觉和记忆是一个整合的认知系统。由于知觉和记忆提供了表象生成的材料,因而三者共享相似的表征,并激活广泛而相似的脑区。然而在认知加工过程上三者存在一定的差异。与知觉相比,表象的编码方式更抽象、更依赖过去经验的参与且处理细节能力更弱;与记忆相比,表象更容易受无关信息的干扰。未来对三者关系的研究应关注不同来源和不同类型的表象与知觉、记忆之间的关系,以及工作记忆在三者关系中所起的作用。  相似文献
