In software reliability theory many different models have been proposed and investigated. some of these models intuitively match reality better than others. The properties of certain statistical estimation procedures in connection with these models are also model-dependent. In this paper we investigate how well the maximum likelihood estimation procedure and the parametric bootstrap behave in the case of the very well-known software reliability model suggested by Jelinski and Moranda (1972). For this study we will make use of simulated data. 相似文献

An explanatory model of adolescent problem behavior (problem drinking, cigarette smoking, and general delinquency) based on protective and risk factors in the individual and in 4 social contexts (family, peer group, school, and neighborhood) is employed in school‐based samples from the People's Republic of China (N=1,739) and the United States (N=1,596). Despite lower prevalence of the problem behaviors in the Chinese sample, especially for girls, a substantial account of problem behavior is provided by the same protective and risk factors in both countries and for both genders. Protection is generally higher in the Chinese sample than in the U.S. sample, but in both samples protection also moderates the impact of risk. Despite mean differences in psychosocial protective and risk factors, as well as in problem behavior, in the 2 samples—differences that may reflect societal variation—the explanatory model has, to a large extent, cross‐national generality. 相似文献

This paper examines the socialization and adjustment experiences of newcomers to organizations from a role stress perspective. A longitudinal field study is reported which tested a three-stage socialization model using physiological and psychological distress symptoms, general satisfaction, and intention to leave the organization as indicators of newcomer adjustment. Data were collected from newcomers (the focal role) (N = 91) at three times during me study and also from their supervisors (the role senders) (N = 41). While the data confirmed the general utility of the model, it also suggested some revisions by way of new and altered pathways between some of the variables. 相似文献

Where funded by government, prevalence studies have typically led to the development of services for problem gamblers and their families. Such assessments of the need for services have been seen as the appropriate political response to growing expressions of concern about problem gambling that often follow moves to legislate for an increasing range of gambling products. This theme is apparent for Australia, Canada, New Zealand and the United States. In this paper, initiatives in these different jurisdictions are briefly summarized and tabulated. 相似文献

Twenty-eight adolescent bulimics were compared to 201 psychiatrically hospitalized non-eating disordered patients. Non-eating disordered patients were found to be reliably more aggressive, delinquent, and under-controlled than patients with bulimia nervosa. Sexual abuse was found to be less prevalent among bulimic adolescents than comparison adolescents. No significant between group differences were achieved on any measure of alcohol/drug abuse. The behavioral profiles of substance abusing bulimics were highly similar to those of non-eating disordered patients. Three months follow-up of bulimic patients found that they were less depressed, had less somatization, and were less overcontrolled; however, they showed no reliable improvements in eating attitudes/behaviours or drug/alcohol use. 相似文献

As an element of formal organizational structure, strategy has arisen as an icon of an increasingly organization-based society, while the application of technology to perform organizational functions has become an accepted aspect of contemporary life. Combined, strategy and technology suggest organizational orderliness, rationality, and efficiency. A variety of literatures has recognized the symbolic role of strategy and technology, as well as professional endeavor, in legitimating organizational functioning and change, wherein the vested political interests of an organization's strategic apex may be veiled by a rhetoric of objectivity and professionalism. However, this literature has remained largely theoretical in nature. An ethnographic field study of the Big 6 public accounting firms examined the interpenetration of strategy, technology, and internal social processes. It found, for example, that audit technologies were developed and unilaterally implemented by the strategic apex of the firms to achieve such stated objectives as enhancing auditor “efficiency.” However, the implemented technologies were frequently resisted, transformed, and redirected to serve the ends of the operating core, or practitioner subculture, of the firms. Thus, strategy, technology, and social process are seen as interpenetrated within the active political-social milieu that is public accounting. 相似文献

This study explored the promotion of recycling in multi-family dwellings. An experimental design investigated four behavior
change techniques: biweekly postcards giving specific feedback to each dwelling unit as to quantity and contamination of the
recyclables, newsletters giving general information on recycling and the amount recycled by the city as a whole, written pledges
committing households to recycle for a specified period, and volunteer coordinators who distributed information and answered
questions from residents. The effectiveness of these techniques was compared against that of a control group. The findings
suggest that volunteer coordinators are not an effective intervention technique in multi-family dwellings, and that feedback
and commitment techniques are useful mainly for managing contamination in medium sized complexes. The data also suggest that
the size of a multi-family dwelling complex significantly affects the amount of recyclables collected and the level of contamination.
Smaller complexes with less than ten units recycled up to three times the amount on a per unit basis as complexes with more
units. Smaller units also had fewer problems with contamination in their recyclables. Several explanations are offered for
the poor participation and performance in larger complexes. 相似文献
