The present study was conducted with 1,632 college vocational students in North Carolina to test the job satisfaction postulate of Rusbult's (1980a) investment model. The model postulate, that satisfaction is a function of perceived positive and negative outcomes, received support and proved to be defensible even after controlling for a broad array of situational variables. This postulate has also received empirical support from studies of satisfaction with business relationships, friendships, and romantic associations. The present study also introduced a new measure of outcomes: the Perceived Outcomes of College Life measure. 相似文献

Newlyweds' preferences for the sex of their prospective children were explored via forced-choice surveys. The results indicate that the ideal family size has changed over the past 20 years from 3–4 children to 2–3 children. The desire to have children of both sexes has not changed. However, in families with an unequal gender ratio, a majority of boys was preferred over a majority of girls. Boys were preferred as first-born children among those with a preference, although the no preference option was chosen by nearly three quarters of the sample. There was great variance in the amount of agreement within couples on the ideal family formation, and there was more disagreement than agreement, indicating a potential source of conflict for newlyweds. 相似文献

Error theories about morality often take as their starting point the supposed queerness of morality, and those resisting these arguments often try to argue by analogy that morality is no more queer than other unproblematic subject matters. Here, error theory (as exemplified primarily by the work of Richard Joyce) is resisted first by arguing that it assumes a common, modern, and peculiarly social conception of morality. Then error theorists point out that the social nature of morality requires one to act against one's self‐interest while insisting on the categorical, inescapable, or overriding status of moral considerations: they argue that morality requires magic, then (rightly) claim that there is no such thing as magic. An alternate eudaimonist conception of morality is introduced which itself has an older provenance than the social point of view, dating to the ancient Greeks. Eudaimonism answers to the normative requirements of morality, yet does not require magic. Thus, the initial motivation for error theory is removed. 相似文献

One of the most consistent findings in the criminological literature is that African American males are arrested, convicted, and incarcerated at rates that far exceed those of any other racial or ethnic group. This racial disparity is frequently interpreted as evidence that the criminal justice system is racist and biased against African American males. Much of the existing literature purportedly supporting this interpretation, however, fails to estimate properly specified statistical models that control for a range of individual-level factors. The current study was designed to address this shortcoming by analyzing a sample of African American and White males drawn from the National Longitudinal Study of Adolescent Health (Add Health). Analysis of these data revealed that African American males are significantly more likely to be arrested and incarcerated when compared to White males. This racial disparity, however, was completely accounted for after including covariates for self-reported lifetime violence and IQ. Implications of this study are discussed and avenues for future research are offered. 相似文献

Abstract Premarital counseling programs have been proliferating in the United States since their appearance in the 1930s. In order to evaluate the success such programs have had in preparing couples to build successful marriages, reduce the incidence of divorce and prevent unsuccessful marriages from occurring, the authors reviewed those programs which outlined standardized intervention procedures and utilized dependent measures to assess the program's effectiveness. Thirteen programs met these criteria. In general, premarital counseling programs were found to be atheoretical in their approach to intervention, loosely designed and nonspecific as to their goals. 相似文献

Eighty male subjects participated in a tetradic weighted-majority game in which a coalition was required to control the division of the payoff. The amount of the payoff and/of the probability of receiving the payoff were varied. The data strongly supported the hypothesis that subjects would prefer the coalition with the largest expected value (size of payoff x probability of success = expected value) rather than the coalition with the largest payoff or the coalition with the highest probability of success. However, contrary to expectations, the 'division of rewards was found to be a function of the relative assigned resources of the coalition members, despite the lack of a logical connection between the assigned resources and the rules governing obtaining the payoff. 相似文献

Employees of a corporation who had undergone considerable training for effective teamwork were asked to brainstorm about a job-relevant issue in groups of four or alone. One half of the groups brainstormed alone first, and the other half brainstormed as a group before brainstorming alone. Participants were also asked to rate their performance and indicate whether they would perform better in groups or alone on a brainstorming task. Consistent with past laboratory research, groups generated only about half as many ideas as a similar number of individuals (nominal group), and group brainstorming led to more favorable perceptions of individual performance. Participants also believed that they would brainstorm more effectively in a group than alone. These results indicate that productivity losses in brainstorming groups are not restricted to laboratory groups. Such losses occur even in groups who work together on a daily basis, have considerable training in group dynamics, and are dealing with a job-relevant issue. The sequence of alone to group brainstorming did not influence overall productivity. The relation of this research to that of facilitated and electronic brainstorming is discussed. 相似文献

Over the years, people have searched for deception cues in the liar's behavior. However, the sender's incentives to lie might be more revealing than behavior. In Experiment 1, an incentive was developed that was predictive of lying. Judges with access to incentive information in addition to behavior achieved almost perfect lie/truth detection. This was not a result of the speakers' behavior being transparent (Experiment 2) but because incentive information was useful to separate lies from truths (Experiments 2 and 3). Experiment 3 revealed that people may forego perfectly diagnostic contextual cues to base their judgments on illusory behavioral cues. 相似文献

Much of what we need to plan for our survival is already known, but what we know, how we know, and who knows is divided up between disciplines. Thus much of the problem of ensuring our survival is a matter of learning across the disciplines. We identify four modes through which we bring disciplinary knowledge together: the unity of science, integrated assessment, heuristic models, and distributed learning networks. Although none of them are perfect, we can learn how to put our knowledge together across the disciplines much better than we do. 相似文献

Three aspects of electronic communications technology are described: convergence of modes, communities of interest, and impacts on culture. Nine recurring aspects of technology and its use, which are particularly pertinent to our time, are discussed. 相似文献
