We examine the two traditions of content analysis: the first in which one substitutes words of a text with categories, and the second in which one looks for clusters of words that may refer to a theme. In the first tradition, preexisting dictionary categories give meaning to the words; in the second, meaning comes after the fact. Preexisting dictionary categories (the substitution model) are calibrated instruments applied within experimental designs that leave no space for doubt; meanwhile, the ability of the correlational model to conjure up complex themes from fragments of a text yields no unique solution. These differences have bearings on the production of new social knowledge. We expound on the epistemological foundations of the two traditions of interpretation and draw from them decision rules upon which one may rely for choosing among appropriate content-analytic tactics. Two reasons make this essay timely and critical: (1) the increasing variety of new content-analyticsoftware for particular purposes and (2) the almost exclusive focusing on software and technology at the expense of adjusting the choice of the software to the nature of the text. Two studies, one in historiometry, the other in autobiography, illustrate the liabilities and benefits of the two models of content analysis.  相似文献

The purpose of this study was to (a) compare the occupational sex stereotypes of 366 college students with those reported by Shinar in 1975, and (b) examine the relationships between demographic, experiential, and attitudinal variables and these occupational sex stereotypes. The results indicated a significant difference in occupational ratings from Shinar's study, with females' perceptions shifting more than males' perceptions. In addition, subjects' gender, tenure with female managers, and attitudes toward women as managers, were shown to be significant predictors of occuptational ratings. The implications of these findings for both employees and managers are then discussed.  相似文献

在我国上市公司“既分又配”的现象普遍存在,这种有悖于一般财务政策的行为为什么会存在呢?国内的学者很少进行研究,本文就在已经分红的基础上从影响“既分又配”股利政策的因素人手,通过实证分析,发现仅有资产规模、净资产盈利率、股市行情等对“既分又配”有明显的影响,而且影响的方向与我们预期的相同。但是,企业的成长能力、股权自由流量的影响并没有得到实证分析的证明,有待于进一步研究。  相似文献

实践中,行政不作为违法给公民、法人及其他组织的合法权益造成的损害程度不亚于行政作为违法,我国的《国家赔偿法》在此方面的规定存在不足。本文将从该法有关行政不作为违法的立法缺失入手,肯定国家对此应当承担赔偿责任,浅析此举的意义,最后分析了如何将《国家赔偿法》中行政不作为违法纳入国家赔偿机制。  相似文献

关于基本经济制度的三点探索   总被引:2,自引:0,他引:2  
党的十六大重申社会主义初级阶段的基本经济制度,不仅再次肯定公有制为主体,并且把多种所有制经济包括私营经济也纳入,是对传统理论的一大突破。这是从现阶段的实际出发,有着多样的现实条件。强调两个"毫不动摇",澄清了不同看法,其结果很可能形成混合经济居大的格局:宏观上是多种所有制经济并存,微观上是产权多元化的股份制公司为典型。坚持和完善基本经济制度,有一系列的对策,除深化国有、集体企业改革和鼓励、支持、引导非公有制经济发展外,令人想起毛泽东曾经讲过的四句话:"公私兼顾、劳资两利、城乡互助、内外交流"。  相似文献

Individuals, differing in productivity and life expectancy, vote over the size and type of a collective annuity. Its type is represented by the fraction of the contributive (Bismarckian) component (based on the worker's past earnings) as opposed to the non‐contributive (Beveridgean) part (based on average contribution). The equilibrium collective annuity is either a large mostly Bismarckian program, a smaller pure Beveridgean one (in accordance with empirical evidence), or nil. A larger correlation between longevity and productivity, or a larger average life expectancy, both make the equilibrium collective annuity program more Beveridgean, although at the expense of its size.  相似文献

In equity markets, it is common to find calendar anomalies, which have been the subject of several studies in recent decades, even some of them showing that over time these anomalies have disappeared. In this context, this paper analyzes one of these anomalies, the end-of-the-month effect, in both return and volatility in six Latin American stock markets, namely Brazil, Mexico, Chile, Colombia, Peru and Argentina during the period of 1993-2011. The importance of the evidence for the existence of this anomaly is to allow testing whether the effect has been disappearing over time. The findings of this research show the existence of positive abnormal returns and abnormal volatilities on days associated with the change of months for most of the countries under analysis. This research was performed according to three different periods defined in the literature to analyze the impact of the end-of-the-month effect. This research not only examines the key indexes of each market, but also the individual stocks of each, giving a much larger and demanding sample, which can lead to better conclusions about the existence of the phenomenon. Also, the transaction volume analysis is included to validate some hypotheses related with the high cash flow in the turn-of-month period.  相似文献
