Indecisive students often present with social skills problems, which may make academic and vocational decision‐making tasks difficult and complex for them. Moreover, choices regarding one's future require the ability to gather information, to search for help and support, to stave off intrusiveness and pressures, and to communicate one's decisions. Social competencies, particularly, play a significant role in vocational guidance activities. This article presents a training program devised to augment assertive competencies in indecisive students choosing a university course of study. Intended aims and the analyses to assess the efficacy of the intervention through self‐evaluation and role‐play assessment are described.  相似文献

Cohen (1997) employed the term “classical” diaspora in reference to the Jews. Indeed, a vast corpus of work recognizes the Jewish people as examples of quintessential diasporic groups. However, a broader conceptualization of the term diaspora allows for the inclusion of immigrant communities that would be otherwise sidelined in the conventional literature on diaspora. This study is therefore a departure from the traditional diasporic literature, which tends to use the Jewish Diaspora as the archetype. It favours, rather, the classification of three principal broad historical waves in which the Jewish Diaspora can be interpreted as part of a classical period. The historicizing of diasporization for the purpose of this paper is achieved by an empirical discussion of the three major historical waves that influenced the diasporic process throughout the world: the Classical Period, the Modern Period, and the Contemporary or Late‐modern Period. The paper discusses these three critical phases in the following manner: first, reference is made to the Classical Period, which is associated primarily with ancient diaspora and ancient Greece. The second historical phase analyses diaspora in relation to the Modern Period, which can be interpreted as a central historical fact of slavery and colonization. This section can be further subdivided into three large phases: (1) the expansion of European capital (1500–1814), (2) the Industrial Revolution (1815–1914), and (3) the Interwar Period (1914–1945). The final major period of diasporization can be considered a Contemporary or Late‐modern phenomenon. It refers to the period immediately after World War II to the present day, specifying the case of the Hispanics in the United States as one key example. The paper outlines some aspects of the impact of the Latin American diaspora on the United States, from a socio‐economic and politico‐cultural point of view. While the Modern and Late‐modern periods are undoubtedly the most critical for an understanding of diaspora in a modern, globalized context, for the purpose of this paper, more emphasis is placed on the latter period, which illustrates the progressive effect of globalization on the phenomenon of diasporization. The second period, the Modern Phase is not examined in this paper, as the focus is on a comparative analysis of the early Classical Period and the Contemporary or Late‐modern Period. The incorporation of diaspora as a unit of analysis in the field of international relations has been largely neglected by both recent and critical scholarship on the subject matter. While a growing number of studies focus on the increasing phenomenon of diasporic communities, from the vantage of social sciences, the issue of diaspora appears to be inadequately addressed or ignored altogether. Certain key factors present themselves as limitations to the understanding of the concept, as well as its relevance to the field of international relations and the social sciences as a whole. This paper is meant to clarify some aspects of the definition of diaspora by critiquing the theories in the conventional literature, exposing the lacunae in terms of interpretation of diaspora and in the final analysis, establishing a historiography that may be useful in comparing certain features of “classical” diaspora and “contemporary” diaspora. The latter part of the paper is intended to provide illustrations of a contemporary diasporic community, using the example of Hispanics in the United States.  相似文献

Who votes in ASA elections? This article examines data on voter turnout from two recent presidential contests of the American Sociological Association in an analysis of the determinants of election participation. Extending the 1981 Ridgeway and Moore study of voting dynamics in the ASA, we hypothesize that intraorganizational networks and particular demongraphic characteristics link ASA members to the discipline in a manner analogous to the way such factors operate in the national electorate. On the basis of data compiled from 1985 and 1986 ASA election returns, we find that network factors are the most salient determinants of voting behavior. We conclude that those organizational ties that effectively link members, however directly or indirectly, to the larger Association are the most predictive of propensity to vote.  相似文献

Summary In this paper the factorial structure of some asset returns quoted at the Milan stock exchange is analyzed in order to detect the presence of a dynamic component. The maximum likelihood estimates of the dynamic model, for which a space-state representation and the Kalman filter were used, are compared with the estimates of the static model via the information criteria. There is no evidence of dynamic factors underlying the analyzed samples of asset returns, while one static factor seems to be relevant.

Models of Neurotoxicity: Extrapolation of Benchmark Doses in Vitro   总被引:4,自引:0,他引:4  
In risk assessment, no observed exposure level (NOAEL) and benchmark dose (BMD) are usually derived either from epidemiological studies in humans or from animal experiments. In many in vitro studies, concentration-effect/response curves have been analyzed using different mathematical models finalized to the identification of EC50. In the present article, we propose a model to fit dose-response curves in vitro. The BMD approach has been used to compare the cell viability (MIT assay) of different rat (C6 and PC12, glial and neuronal, respectively) and human cell lines (D384 and SK-N-MC, glial and neuronal, respectively) after 24-hour exposure to the following neurotoxic substances: manganese chloride (MnCl2), methyl-mercury (Me-Hg), and the enantiomers of styrene oxide (SO). For all rat and human cell lines, the potency of the examined compounds was: MnCl2 < S-SO < R-SO < Me-Hg. A preliminary comparison with in vivo toxicity data for these substances gave rise to consistent results. Whereas a reasonable agreement between in vitro and in vivo data has been found for Mn and styrene oxide, a wide scatter of LOAEL has been reported for Me-Hg and these appear to be either much higher or lower than the BMD for the MIT assay we observed in vitro.  相似文献

Summary In this paper the minimum of the expected value of the product of three random variables is studied as their joint distribution function varies in the Fréchet class associated to the three given marginal distribution functions. The general problem is studied for three positive valued random variables and a lower bound for the minimum is provided. The case of three uniformly distributed random variables in [0, 1] is analyzed in more detail and an upper bound for the minimum is given. The Author conjectures that the distribution correspondent to the upper bound is a solution of the problem. Paper written with the contribution of MURST (funds 40%).  相似文献
