This paper summarizes the results of previous work on the microscopic observation of linear dichroism found in dyed fibres (polyesters, polyamides, wool, silk, cotton, viscose, acrylics and acetates) and in pigmented fibres as well as the measurements on these fibre classes using microspectrophotometry with plane polarized light (MSP-PPL). The validation of this method is discussed and a practical tool is proposed for comparing fibre traces with control fibres. The limitations and strengths of this method are also revised. 相似文献
We analyze the way in which individual academics and research groups organize their third mission activities before and after the institutionalization of third mission strategies by the university governing body. Drawing on the literature, we put forward an interpretative framework that links central entrepreneurial or engaged strategies with the way academics organize their third mission activities. Then, we propose an application of this frame to the case of the University of Florence (Italy), before and after its transition to more structured entrepreneurial and engaged models. We use a mix of quantitative and qualitative analysis. A cluster analysis allows identifying different types of academics involved in the third mission based on the way they organize their activities. Furthermore, a set of interviews to academics complements the comparison and the interpretation of the clusters obtained. The following paths of change emerge: (1) increased proportion of academics involved in third mission activities; (2) bottom-level initiatives that are aligned with central strategies; and (3) increased heterogeneity of bottom-level organization forms, with a relative loss of importance of the group dimension with respect to the individual academics and an increased specialization of research groups.
In the present studies, we aimed to show that the perceived procedural fairness of societal actors’ multicultural decisions promotes ethnic minority members’ societal identification. These enhanced identification levels, in turn, contribute to better psychological health and well-being. Firstly, a vignette study in a sample of African Americans explored the effect of procedural fairness climate on identification. The second and third studies used self-report questionnaires. Study 2 consisted of a sample of sojourners in a university context, Study 3 analyzed online data through an African American sample. The studies provided evidence for the effect of procedural fairness climate on increased societal identification, which in turn mediates the fairness effect on increased well-being and psychological health. Societal actors can use procedural fairness to increase well-being when making decisions that involve ethnic minorities.
Considerable research has focused on the reliability and validity of informant reports of family behavior, especially maternal
reports of adolescent problem behavior. None of these studies, however, has based their orientation on a theoretical model
of interpersonal perception. In this study we used the social relations model (SRM) to examine family members’ reports of
each others’ externalizing and internalizing problem behavior. Two parents and two adolescents in 69 families rated each others’
behavior within a round-robin design. SRM analysis showed that within-family perceptions of externalizing and internalizing
behaviors are consistently due to three sources of variance; perceiver, target, and family effects. A family/contextual effect
on informant reports of problem behavior has not been previously reported. 相似文献
This paper seeks to analyze the policies on the cultural field implemented in Chile in recent years, explaining how expertise became fundamental and, more specifically, how this expertise evolved from that of an expert intellectual to that of an expert professional. The paper is based on the general hypothesis that the cultural field needs to be viewed in the context of a growing differentiation and autonomization of Chilean society, but that there are some interesting nuances to its evolution, particularly with regard to the transformation of expertise. This article argues that the expert in culture has a twofold nature, which is illustrated through drawing a timeline from the 1980s to the present, marking certain milestones in Chile’s national and cultural history. This timeline incorporates the intellectual work of two of Chile’s most important contemporary sociologists and experts in culture and cultural policies, Manuel Antonio Garretón and José Joaquín Brunner. A sample of their publications is analyzed and then contrasted to documents on cultural policy since the approval of the country’s institutional framework for culture in 2003, when the National Council for Culture and the Arts was created, gauging the influence of the expert intellectual on this new institutional framework and the thrust of public policies on culture. The paper concludes that the figure of the expert in culture has shifted from the “expert intellectual” to the expert of a professional kind, although the theoretical work of the former has continued to influence the debate around cultural policies to this day. 相似文献
Drawing on institutional theory, this article articulates qualitative insights from a program of research on Canadian health technology‐based ventures to examine the rules that characterize economic policy, capital investment, and regulatory approval as well as the way these institutions enable and constrain the development of ventures at an early stage. Our findings clarify how economic policy integrates these ventures into the entrepreneurial domain, how capital investment configures them for economic value extraction, and how regulatory approval fully releases their market value. These findings help to revisit current policy modernization initiatives by calling attention to the convergence among the three institutions. Rather than operating solely as a source of constraints, these institutions provide a highly integrated market‐oriented space for health technology‐based entrepreneurial activities to unfold. 相似文献
The purpose of this paper is to discuss how fascism may be identified by its actions, the stages through which a fascist rule takes power, and how to recognize it before it does so. The thesis is that a fascist takeover of a democratic government is rapid and unexpected. Its goal is a revolutionary reversal of representative government in the name of the people, while it accomplishes the opposite: a single-party corporate regime that replaces individual liberty with subtle, bureaucratic, and overt types of coercion. Rather than generate a generic definition of the many types of fascism, it is more useful to study how it affects the lives of ordinary people, the milieu out of which it develops, and what its precursors look like. Understanding fascism entails studying it from the point of view of those who lived under it and recorded their experiences, as well as from the analytic perspectives of social scientists. As Robert O. Paxton observes: “The fascist phenomenon was poorly understood at the beginning in part because it was unexpected.”1Robert O. Paxton, “The Five Stages of Fascism,” in Fascism: Critical Concepts in Political Science, edited by Roger Griffin, vol. I (2004), Chapter 14, 305–26.View all notes We are facing the question again in 2017 with the surprise election of Donald Trump as the forty-fifth president of the United States by a minority of the popular vote and the evident support of the white nationalist milieu. Paxton proposes a five-stage theory for understanding fascism in its many varieties. A developmental sequence is proposed against which current events in the United States may be assessed. 相似文献
