College students (N = 446) and faculty (N = 97) completed a survey examining views of cheating. Agreement was noted on most situations. When differences were noted, students tended to be stricter than faculty in their evaluations and were more likely than faculty to label a situation as cheating. Opinions and views of cheating were influenced more by behavior, whether “premeditated” or “opportunistic,” than by intention.  相似文献

This article reports the results of a positive youth development (PYD) intervention for adolescents in alternative high schools (209 African American and Hispanic American adolescents, aged 14–18; 118 females and 91 males). The intervention was guided by a self‐transformative model of PYD (Eichas, Meca, Montgomery, & Kurtines, 2014). This model proposes that the actions youth take to define themselves function as active ingredients in positive development over the life course. Consistent with the self‐transformative model, results provided support for direct or mediated intervention effects on the self‐transformative processes of self‐construction and self‐discovery, life goal development, identity synthesis, and internalizing problems. The findings illustrate the utility of using a self‐transformative approach to PYD in work with marginalized youth populations.  相似文献

Cancer is a genetic disorder.Although heredi-tary cancers account for only a small fraction of all tumors,most cancers are caused by a variable mix of heredity and environment that leads to accumulations of genetic alterations and then uncontrolled cell pro-liferations(Kops et al.,2005).In addition,genetic alteration is one of the a few most important bio-logical factors that determine the diagnosis and prognosis of different cancers and dictate the treat-ment strategies for cancer patients.Fu…  相似文献

Abstract

Rural landholders are undergoing extended economic hardship, manifested in a range of social and ecological problems that limit the capacity of local areas to recover to economic levels necessary to sustain settlement. The uncertain influence of climate on production represents just one of the range of risk factors that landholders must face. Survival depends on the capacity of landholders to respond strategically to the stress which these risk factors generate. Our research indicates landholders’ capacity to modify land‐management practices, are dictated by their underlying personality traits and by presence or absence of other psychiatric morbidity. Where stresses exist, the capacity of people to respond actively to a planned problem solution diminishes. The psychological profiles of people tend to fall into three groups ‐ those who can generally cope; those who can usually cope but undergo dysfunctional episodes under acute stresses, and those who generally cannot cope.

In the grazing lands of central western Queensland, our findings suggest a predominant personality profile consistent with an ability to cope with isolation and the other particular challenges that characterise this way of life. There are two important implications in these results. The first relates to land stewardship and has significant lessons for government intervention in terms of rural policy and approaches to extension. In particular, there are lessons pertinent to the success of Landcare and associated community based initiatives. The second relates to the broad area of rural health as highlighted by the alarming rates of suicide found in rural Australia. In previous decades, those with personality styles less well‐suited to this industry, found employment in nearby rural towns. This option has declined as government policy has favoured the withdrawal of services and resources, hastening depopulation of rural areas. The resultant weakening of the social fabric of rural society is a cause of tension and stress with serious health implications. Previous approaches to rural sociology have not emphasised individual personality traits in seeking to understand the complexity of the human‐environment relationships which determine land use. Nor has personality been invoked is assessing the potential of landholders to adopt ecologically sustainable practices. Further research is planned to consolidate our findings through comparative investigations in other branches of rural industry. JAgr Educ Ext (2001, 7, 3, pp 167–178)  相似文献

Two Lagrange multiplier (LM) methods may be used in specification searches for adding parameters to models: one based on univariate LM tests and respecification of the model (LM‐respecified method) and the other based on a partitioning of multivariate LM tests (LM‐incremental method). These methods may result in extraneous parameters being included in models due to either sampling error or the model being misspecified. A 2‐stage specification search may be used to reduce errors due to misspecification. In the 1st stage, parameters are added to models based on LM tests to maximize fit. Second, parameters added in the 1st stage are deleted if they are no longer necessary to maintain model fit. Illustrations are presented to demonstrate that errors due to misspecification occur with the LM‐respecified method and are even more likely with the LM‐incremental approach. These illustrations also show how the deletion stage can help eliminate some of these errors.  相似文献
