This study examines the theory of planned behavior (TPB) and the multidimensional ethics scale (MES). Variables from both are included to determine which ones significantly correlate with student ethical behavioral intention in an academic setting. Using a survey, responses are collected from undergraduate business students from two southwestern universities in the United States using a scenario-based approach, looking at individual situations and group situations. SmartPLS was used to assess the results for four scenarios. From the theory of planned behavior, attitude was a significant predictor of behavioral intention across all four scenarios while subjective norm was significant in one scenario. From the multidimensional ethics scale, moral equity and relativism were significant in one group scenario while moral equity and utilitarianism were each significant in an individual scenario. The findings indicate support for the use of the TPB and the MES when exploring ethics in an academic setting and for the need to study both individual and group situations. A discussion of the findings and implications is given.  相似文献

In a variety of measurement situations, the researcher may wish to compare the reliabilities of several instruments administered to the same sample of subjects. This paper presents eleven statistical procedures which test the equality ofm coefficient alphas when the sample alpha coefficients are dependent. Several of the procedures are derived in detail, and numerical examples are given for two. Since all of the procedures depend on approximate asymptotic results, Monte Carlo methods are used to assess the accuracy of the procedures for sample sizes of 50, 100, and 200. Both control of Type I error and power are evaluated by computer simulation. Two of the procedures are unable to control Type I errors satisfactorily. The remaining nine procedures perform properly, but three are somewhat superior in power and Type I error control.A more detailed version of this paper is also available.  相似文献

Home visiting services for caregivers of infants and young children have been found to be an effective method for promoting child development. Unfortunately, such services suffer from high rates of attrition, suggesting the need to identify factors related to client retention in services. Research has indicated that the client-provider relationship is an important predictor of client retention in home visiting services; however, measures to assess this relationship are limited. This study reports on a pilot test of the Client Perceptions of Home Visitors Questionnaire, developed to assess home visiting clients’ perceptions of their relationship with their home visitor. The measure was completed by 39 diverse home visiting clients during pregnancy in a midwestern town in the United States. The scale was found to have good internal consistency. Validity analyses found that the scale was positively associated with client satisfaction with services and perceived provider cultural sensitivity. The scale was also positively associated with retention in services at an 8-month follow-up. Additional research should examine the measure's psychometrics with larger samples.  相似文献

When intrafaith couples' religion strictly prohibits premarital sexual intercourse, negotiating sexual intimacy can become a multilayered process of identity negotiation that compounds the difficulty of sexual communication. Through the lens of relational turbulence theory, this study explored how devout Christian couples negotiate sexual intimacy by reanalyzing qualitative interview data the first author collected in 2017 from 16 self-identified Christians (8 heterosexual couples). Seven themes revealed how relational uncertainty, partner interference, and partner facilitation manifested in the context of sexual intimacy negotiation. Themes of relational uncertainty experience and prevention included assumption of shared values, relationship talk, and sexual behaviors as an uncertainty catalyst. Partner facilitation and interference emerged as themes of sexual escalation and de-escalation including snowball effect, pinpointing underlying motivations for boundary violations, gatekeeping sexual temptation, and drawing from shared values of sacrifice and prayer. These interpretive findings advance the literature on relational turbulence theory and provide Christian dating couples with practical advice for how to negotiate sexual intimacy in committed premarital relationships.  相似文献

Childhood obesity is a serious health concern that is not yet fully understood. Previous research has linked obesity with neurobehavioral factors such as behavior, cognition, and brain morphology. The causal directions of these relationships remain mostly untested. We filled this gap by using the Adolescent Brain Cognitive Development study cohort comprising 11,875 children aged 9–10. First, correlations between the age- and sex-specific 95th BMI percentile (%BMIp95) and neurobehavioral measures were cross-sectionally analyzed. Effects were then aggregated by neurobehavioral domain for causal analyses. Behavioral genetic Direction of Causation modeling was used to test the direction of each relationship. Findings were validated by longitudinal cross-lagged panel modeling. %BMIp95 correlated with impulsivity, motivation, psychopathology, eating behavior, and cognitive tests (executive functioning, language, memory, perception, working memory). Greater %BMIp95 was also associated with reduced cortical thickness in frontal and temporal brain areas but with increased thickness in parietal and occipital areas. Similar although weaker patterns emerged for cortical surface area and volume. Behavioral genetic modeling suggested causal effects of %BMIp95 on eating behavior (β = 0.26), cognition (β = 0.05), cortical thickness (β = 0.15), and cortical surface area (β = 0.07). Personality/psychopathology (β = 0.09) and eating behavior (β = 0.16) appeared to influence %BMIp95. Longitudinal evidence broadly supported these findings. Results regarding cortical volume were inconsistent. Results supported causal effects of obesity on brain functioning and morphology. The present study highlights the importance of physical health for brain development and may inform interventions aimed at preventing or reducing pediatric obesity.

Research Highlights

  • A continuous measure related to obesity, %BMIp95, has correlations with various measures of brain functioning and structure
  • Behavioral genetic and longitudinal modeling suggest causal links from personality, psychopathology, and eating behavior to %BMIp95
  • Results also indicate directional links from %BMIp95 to eating behavior, cognition, cortical thickness, and cortical surface area
  • Obesity may play a role for healthy brain development during childhood

LA Universal Self reports his phenomenology, according to which, as he puts it, ‘I am the universe’. The Interviewer challenges the report in a variety of ways, and LA Universal Self responds to each challenge. A traditional Universal Self mysticism is given a new physicalist interpretation.  相似文献

Over the past two decades the educational policies of neo-liberal nation states have exhibited contradictory tendencies, promoting both bureaucratic standardization of curriculum and standardized evaluation on the one hand, and postmodern diversification on the other. Despite recent increases in bureaucratic standardization, I argue that the economic, social and cultural effects of globalization will pressure these states towards postmodern diversification of educational arrangements to strengthen their perceived legitimacy.  相似文献

Policy is the product of a group struggle between contending factions who constantly strive to weight policy creation and decision making in their favor. Within social service settings, resource policies promoted by management compete with service policies of social workers. Management familiarity with information technology (IT) rewards operational advantage in resource application at the expense of social work personnel. Within the Israeli Ministry of Labour and Social Affairs this has enhanced the position of the manager. Social workers failed to incorporate IT within the natural systems approach resulting in a state of disempowerment vis à vis IT itself. The social worker will be able to avail himself of IT only consequent to redefinition of social services organization policy based on social work concepts such as social change, involvement, informal organization and empowerment. His current interest is the knowledge base of social work. He has written widely on social work and the personal social services, with particular reference to dependency, empowerment and new technology.  相似文献
