Because they were participating in a concurrent panel study, 222 older adults had been asked how much help they would expect to receive in a hypothetical emergency before experiencing two separate floods. For the subsample suffering losses or injuries during the floods, Study 1 examined the accuracy of their expectations, as well as possible changes in them, as a result of help actually received. Generally, victims received much less help than they had expected to receive prior to the floods. Preflood expectation of support predicted help from kin, whereas loss and education predicted help from nonkin sources. However, subsequent expectations did not change as a result of the level of help received. Using the total sample, Study 2 examined the broader issue of whether the disaster itself affected subsequent perceptions of support. Flood exposure, as measured at both individual and community levels, was associated with declines in perceptions of support and social participation.  相似文献

Social networks with two sets of actors   总被引:1,自引:0,他引:1  
Traditional network research analyzes relational ties within a single group of actors: the models presented in this paper involve relational ties exist beteen two distinct sets of actors. Statistical models for traditional networks in which relations are measured within a group simplify when modeling unidirectional relations measured between groups. The traditional paradigm results in a one-mode socionatrix; the network paradigm considered in this paper results in a two-mode socionatrix; A statistical model is presented, illustrated on a sample data set, and compared to its traditional counterpart. Extensions are discussed, including those that model multivariate relations simultaneously, and those that allow for the inclustion of attributes of the individuals in the group.We thank the Editor and two anonymous reviewers for their helpful comments. We are also grateful to George Barnett for allowing us to analyze his data.  相似文献

In four experiments, observers attempted to align two sets of oblique edges to parallel. The contexts for these alignments included lines in isolation (2-D control), lines embedded in orthogonal drawings of same-oriented and different-oriented boxes (3-D objects), and each of these viewed against backgrounds depicting strong linear perspective (3-D backgrounds). A consistent distortion was observed in the alignments of different-oriented boxes relative to control lines, indicating that the parallel lines in these stimuli appeared to diverge toward the top of the picture. Furthermore, thisbox alignment illusion decreased with interstimulus distance, whereas alignment distortions in control lines and same-oriented boxes increased with distance. Viewing the stimuli against 3-D backgrounds produced a dramatic reversal of the illusion, with control lines now appearing to converge more than the boxes. These results suggest that the illusion reflects basic processes involved in pictorial depth perception.  相似文献

Summary This essay has been by necessity a gloss of a complex look at the relations of power, control, and personal identity construction in a workplace. Features of the nature of the work process combine with social strategies to construct a reproductive self-referential system. Corporate organizations are central institutions in contemporary life; they make developmental decisions for individuals and for society as a whole. While they are in this sense political to the core, we have not done enough to understand how this politics works or to explore its relation to people in a democratic society. Using a phenomenologically-based communication analysis enables a sensitive analysis of the multiple forms of power and domination as they exist in corporate sites. Although I have given only an outline of one case study here, this example suggests that phenomenologically-based projects can show harmful and unwarranted control, and can be a first step to fostering corporate practices that lead to decisions which are less wasteful of resources and more fully accomplish the goals of democratic society.Funding for the research project from which the case study was derived was provided by the Rickart Malmsten Foundation (Sweden).  相似文献

As researchers become more interested instudying the influences of the male gender role onpeople's physical and psychological well-being, measuresof several male role domains have been created,including psychological agency, traditional attitudestowards men, and masculine gender role stress (MGRS).These measures of the male gender role, however,typically have been constructed and validated using only samples of men. This restriction introducesquestions about the reliability and validity of theseinstruments in samples of women, leading to problemswhen generalizing findings to this group. The present study addressed these issues by examining thefactor structure, factor correlations, and latent meansof these three male role measures for a sample of mostlyCaucasian men and women, using multiple group confirmatory factor analytic techniques.Results showed only the dimensionality of the agenticpersonality traits differed significantly for men andwomen. The interrelationships among and latent means of agency, attitudes, and MGRS differed by sex.These findings demonstrate the utility of the currentconceptualization of sex and gender; in other words,that gender is not totally determined by sexand that men and women internalize many of the samegender cues, but differentially endorse them to varyingdegrees.  相似文献

Determinate solutions for the indeterminate common factor ofp variables satisfying the single common factor model are not unique. Therefore an infinite sequence of additional variables that conform jointly with the originalp variables to the original single common factor model does not determine a unique solution for the indeterminate factor of thep variables (although the solution is unique for the factor of the infinite sequence). Other infinite sequences may be found to determine different solutions for the factor of the originalp variables. The paper discusses a number of theorems about the effects of additional variables on factor indeterminacy in a model with a single common factor and draws conclusions from them for factor theory in general.  相似文献

An on-line assessment system is briefly described. Previous positive evaluation studies are summarized. Results of studies of staff acceptance and staff preparedness for change are reported. Findings are interpreted in terms of the need for planning for change. Implications related to the acceptance of other on-line computer systems in psychology are discussed.  相似文献

Twenty subjects judged the average lightness and darkness of paired Munsell gray papers according to magnitude estimation and category rating instructions. The data from category rating were approximately consistent with an averaging model but those from magnitude estimation were not. An analysis in terms of a two-stage model suggested that category ratings and magnitude estimates of each attribute were produced on the basis of the same composition rule, but implicated different output transformations. In judging darkness, subjects appeared to have reversed the scales employed in judging lightness, by a linear transformation in the case of category rating and by a reciprocal transformation in the case of magnitude estimation. However, differences between the input parameters obtained from judgments of lightness and darkness suggested that the scales of these attributes constructed from judgments of average magnitude may be biased.  相似文献

Male and female subjects read four paragraphs portraying successful (experiment 1) or unsuccessful (experiment 2) males or females in masculine or feminine occupations, with a supportive or nonsupportive spouse. The likelihoods of various conflicts, consequences, and causes of the success or failure were rated. Generally, ratings of more negative consequences were associated with lack of spouse support for a career pursuit. Spouse support influenced perceptions of female more than male success. The sex-association of the career proved to be an important determinant of perceptions of conflict, consequences, and attributions for the success or failure. Although male and female occupations had been equated for status, female jobs appeared to be generally devalued relative to male jobs.  相似文献
