Milliseconds matter: an introduction to microstrategies and to their use in describing and predicting interactive behavior

Interactive behavior is constrained by the design of the artifacts available (e.g., a mouse and button) as well as by the ways in which elementary cognitive, perceptual, and motor operations can be combined. Any 2 basic activities, for example, (a) moving to and (b) clicking on a button, can be combined to yield a limited number of microstrategies. The results of an experimental study suggest that alternative microstrategies can be deployed that shave milliseconds from routine interactive behavior. Data from a usability study are used to explore the potential of microstrategies for (a) bracketing the range of individual performance, (b) profiling individual differences, and (c) diagnosing mismatches between expected and obtained performance. These 2 studies support the arguments that the microstrategies deployed can be sensitive to small features of an interface and that task analyses at the millisecond level can inform design.     

异体造血干细胞移植问题、发展与思考

异体造血干细胞移植(Allo-HSCT)已成为治疗恶性血液病及其他各种疾病的有效方法之一。在Allo-HSCT中由于供体和受体免疫屏障的存在。从而一开始就是一个供受体矛盾的对立统一的过程。对其中矛盾的研究和解决充满了辩证唯物的哲学思想。也促使Allo-HSCT技术不断发展。新的方法和理念不断出现。使Allo-HSCT治疗白血病的疗效不断提高。

Mitigating disruptive effects of interruptions through training: what needs to be practiced?

It is generally accepted that, with practice, people improve on most tasks. However, when tasks have multiple parts, it is not always clear what aspects of the tasks practice or training should focus on. This research explores the features that allow training to improve the ability to resume a task after an interruption, specifically focusing on task-specific versus general interruption/resumption-process mechanisms that could account for improved performance. Three experiments using multiple combinations of primary tasks and interruptions were conducted with undergraduate psychology students. The first experiment showed that for one primary and interruption task-pair, people were able to resume the primary task faster when they had previous practice with the interruption. The second experiment replicated this finding for two other sets of primary and interruption task-pairs. Finally, the third experiment showed that people were able to resume a primary task faster only when they had previous practice with that specific primary and interruption task-pair. Experience with other primary and interruption task-pairs, or practice on the primary task alone, did not facilitate resumption. This suggests that a critical component in resuming after an interruption is the relationship between two tasks. These findings are in line with a task-specific mechanism of resumption and incompatible with a general-process mechanism. These findings have practical implications for developing training programs and mitigation strategies to lessen the disruptive effects of interruptions which plague both our personal and professional environments.     

Social Representations of Human Rights Amongst Czech University Students

The Universal Declaration of Human Rights is a general legislative framework for democratic societies. Studying the social representations of these basic human rights helps to explain how people understand and assess the basic rights and how these rights relate to everyday life. Over 400 Czech university students rated the 30 articles of the Declaration of Human Rights on various scales (degree of understanding, personal relevance, consequences for individual responsibility, for government, political parties, etc.). A semantic space was identified in which concepts (i.e. the Articles of the Declaration) could be located. A typology (clusters) of articles was then established within that semantic space. A factor analysis of the scales resulted in a two-dimensional solution (‘positive attitude’ and ‘personal influence’). Five clusters of assessed articles were identified within this semantic space.

Culture in the context of intercultural negotiation.

This study explores culture's effect on behaviors and outcomes in intercultural negotiation and examines how those effects are moderated by role. Eighty U.S. and international students took part in a previously developed negotiation task (Pruitt, 1981) and completed Hui and Triandis's (1986) individualism‐collectivism (INDCOL) scale. Negotiation interactions were coded for information sharing, offers, and distributive tactics. Findings show that a negotiation dyad's collectivism is positively associated with higher joint profit. The effects of culture on both communication behaviors and joint outcomes, however, differ by role of the negotiator. In particular, seller collectivism has larger and more consistent effects on communication behavior and joint profit than buyer collectivism. Results support a ‘culture in context’ perspective of negotiation that takes into account negotiator qualities, contextual and structural features of the negotiation, and mediating processes in addition to cultural values.     

ON THE PRAGMATICS OF SOCIAL THEORY: THE CASE OF ELIAS'S “ON THE PROCESS OF CIVILIZATION”

This paper proposes a new approach to the study of sociological classics. This approach is pragmatic in character. It draws upon the social pragmatism of G. H. Mead and the sociology of texts of D. F. McKenzie. Our object of study is Norbert Elias's On the Process of Civilization. The pragmatic genealogy of this book reveals the importance of taking materiality seriously. By documenting the successive entanglements between human agency and nonhuman factors, we discuss the origins of the book in the 1930s, how it was forgotten for 30 years, and how in the mid‐1970s it became a sociological classic. We explain canonization as a matter of fusion between book's material form and its content, in the context of the paperback revolution of the 1960s, the events of May 1968, and the demise of Parsons’ structural functionalism, and how this provided Elias with an opportunity to advance his model of sociology.
