Segregation of copper in an Fe–Cu alloy under pulsed electric current

Effect of electric current on the segregation of copper precipitates in the Fe–13.6Cu alloy is evaluated. Results of this approach present two stages of segregation, namely, grain-boundary segregation during the solidification and interphase-boundary segregation during the decomposition of a solid solution. The segregation becomes apparent not only because the thermodynamic barrier for segregation is decreased, but also because the diffusion is greatly enhanced. Based on the thermodynamic and kinetic aspects, the segregation process under electric current would be of great interest and of physical importance because this kind of electric current-induced segregation was much stronger than the thermal diffusion segregation.     

The Energy Walk: Experimenting with Aesthetic Methods in STS?

Abstract

In 2014 the research group Alien Energy, based at the IT University of Copenhagen, performed an experiment into the potential of creative intervention as an ethnographic method, in researching the development of new energy forms, such as wave- and geothermal energy. To this end the Energy Walk was created: a carefully choreographed and digitally guided audio walk leading the participant around the harbour area of the Danish town Hanstholm, whilst telling stories of energy and infrastructures. In this paper I argue, that the walk manoeuvres a layered landscape of energetic and infrastructural visibility and invisibility, hereby sensitizing the participant to the manifold energy forms constantly present in our daily lives. Drawing on the aesthetic philosophy of John Dewey I argue, that in doing so, the walk effectively facilitates what he calls an aesthetic experience, and suggest that the walk might best be understood in terms of aesthetic experimentation as a relevant method in STS research.     

“Working with Couples: Satir and the Tao,”

SUMMARY

One of Virginia Satir's greatest gifts to the world was the use of herself as an instrument of healing. By daring to use all of her-self-body, mind and spirit-the connections Virginia made with others were warm and real. Besides being authentically caring, Satir worked out of a pluralistic and comprehensive theoretical base to individualize each intervention. By co-creating strong, trusting relationships she inspirited others with her own life-force energy, and enabled them to become more fully human. Able to put her own ego needs aside, Virginia modeled how to join common sense with a sense of high purpose.     

Imagining ethical globalization: The contributions of a care ethic

Approaches to global ethics have drawn on a number of diverse theoretical traditions, such as Kantianism and utilitarianism. While emerging frameworks contribute to a growing awareness of and interest in ethics within a global society, the values that they prioritize are not adequate for realizing a just, equitable and fair system of global governance. This article considers the possibilities of an alternative ethic—a feminist ethic of care—and explores how it can bear on present circumstances, including global inequity and injustice. This care ethic has been put forward as a viable normative approach to politics and policy. Little attention, however, has been paid to the potential of a care ethic within the globalization and ethics debate. This article illustrates how the values and corresponding principles of care, grounded in relationships and responsibilities, are essential to responding adequately to the current challenges of globalization. By examining the relevance of care in this context, the article seeks to broaden dominant ethical worldviews and contribute to the articulation of normative tools for examining globalization while at the same time avoiding the trappings of conventional universality—the abstract and a priori thinking typically associated with conceptions of global ethics.     

Relational dynamics of charismatic organization: The complementarity of love and power

Abstract: This paper outlines a new theory of structural transformation in charismatic systems by postulating a complementary relationship between love and power. Radical reorganization of social organization, the function of charismatic systems, requires mobilizing and realigning enormous amounts of social energy. The source of this social energy is love. When patterned as communion, love fuses the group into an undifferentiated whole and releases the social energy previously locked up as institutionalized structure.

Released from structure or form, however, social energy is highly volatile and produces immense pressures towards instability. Counterbalancing the pressure from communion, a strong, collective order of power functions to harness and align the energy, thereby promoting group stability and enhancing the prospects for structural transformation. Data from a national study of sixty urban communal organizations are used to ground key aspects of the theory.     

Learning to Optimize Speed,Accuracy, and Energy Expenditure: A Framework for Understanding Speed-Accuracy Relations in Goal-Directed Aiming

Over the last century, investigators have developed a number of models to explain the relation between speed and accuracy in target-directed manual aiming. The models vary in the extent to which they stress the importance of feedforward processes and the online use of sensory information (see D. Elliott, W. F. Helsen, & R. Chua, 2001, for a recent review). A common feature of those models is that the role of practice in optimizing speed, accuracy, and energy expenditure in goal-directed aiming is either ignored or minimized. The authors present a theoretical framework for understanding speed-accuracy tradeoffs that takes into account the strategic, trial-to-trial behavior of the performer. The strategic behavior enables individuals to maximize movement speed while minimizing error and energy expenditure.     

地市级医院医学人文继续教育现状分析——以湖南省6所医院为例

为了解地市级医院医学人文继续教育现状,对湖南省6所地市级医院的医护人员采用问卷调查的方法收集信息,共回收672份有效问卷。数据分析显示,湖南省地市级医院对医学人文继续教育重视程度还有待进一步加强;医院开展医学人文继续教育活动的频率较低,教育方法和手段比较单一,不能因地制宜地与医护人员实际工作有机结合;开展医学人文继续教育的内容和形式没有做到与时俱进。建议地市级医院要高度重视医学人文继续教育工作,积极探索医学人文继续教育新模式,创新医学人文继续教育方式方法,合理凝练医学人文继续教育内容,建立医学人文继续教育激励机制,进一步提升医护人员医学人文素养。     

国内外健康人文研究主题演化的计量分析

采用SciMAT软件、Bicomb软件和SPSS 23.0软件,分别对国内外健康人文研究论文的关键词和研究主题等进行了计量分析。结果表明,健康人文作为一个多学科交融的新领域,研究范围日趋广阔。相比之下,国外健康人文的发文量多、研究主题丰富,国内健康人文研究有着很大发展空间。研究提示,健康人文区别于医学人文的特性将愈加明显,健康人文的研究领域将愈加广阔而深入,护理的健康人文特征将更加鲜明,大健康人文的发展将成为重要方向。
