A first step towards the improvement of daily dietary behaviors is forming an intention to change one's nutrition. However, an intention by itself is not sufficient for successful action. Rather, to translate intentions into behavior, careful planning is recommended. Thus, planning constitutes a mediator between the intention and the behavior. However, if a person lacks self-efficacy, this mediation might fail. Previous research in Costa Rica and South Korea has identified perceived self-efficacy as a moderator of the intention-planning-behavior relationship. To examine further the moderator role of self-efficacy, two additional studies were designed in Thailand and Germany. Study 1 surveyed 1718 Thai university students in terms of a low-fat diet; Study 2 surveyed 1140 German internet users in terms of their fruit and vegetable consumption at two measurement points in time, 6 months apart. Intentions served as predictor, planning as mediator, self-efficacy as moderator, and behaviors as outcomes. First, intentions were translated into nutrition behaviors by planning. Second, self-efficacy moderated this mediation in both studies: The strength of the mediated effect increased along with levels of self-efficacy, even when accounting for baseline behaviors. For planning to mediate the intention-behavior relation, people must not harbor self-doubts. If they lack self-efficacy, intentions are not well translated into nutrition behavior through planning. 相似文献

Mentoring is prototypically intended to advance the personal and professional growth of new employees at work. Although meta‐analyses have found that receiving mentoring can result in beneficial outcomes for employees' career success, employees may perceive barriers to obtaining a mentor. The present research examined antecedents and consequences to perceived barriers to mentoring in business and administrative jobs in a field study over 2 years. Socioeconomic origin, positive affectivity, organizational development culture, and previous mentoring experience predicted perceived barriers to mentoring after 2 years. New employees' perceived barriers to mentoring at Time 1 predicted changes in mentoring received and income after 2 years. Implications of this study, including a proposed mentoring training program, and directions for future research are discussed. 相似文献

In a study often referred to as "classic," Condry and Condry (1976) showed a videotaped infant to participants, telling half of them the infant was a boy and half it was a girl. Participants who thought they were viewing a boy rated the infant's reaction to a jack-in-the-box as anger; those who thought they were viewing a girl rated the reaction as fear. Participants in the present partial replication of the Condrys' study did not rate the infant differently based on the infant's gender label, although there was evidence that participants' own sex affects their perception of an infant's emotionality. Results were discussed in light of inconsistent results among other gender-labeling studies and relevant methodological, historical, and theoretical issues. 相似文献

Common arguments for truth in religious pluralism absolutize an ultimate or lived component of religion, reducing a positive
affirmation of plurality to deeper unity or exclusion. The arguments of John Hick, William Connolly, Nicholas Rescher, and
S. Mark Heim fall into such a trap. By considering how an indeterminate concept of ultimacy, proposed by Robert C. Neville,
fares against the problems their arguments raise, it will be shown that such a concept of ultimacy can both give rise to and
grow out of communal experiences and the nature of the world. The indeterminate ultimate, communal experiences, and the world
pluralize themselves once understood in mutual relation. 相似文献

This paper emphasizes the value of family-centered care. Discussion highlights family-centered philosophies (e.g., Systems of Care [SOCs]) and practice models (i.e., wraparound) and identifies discrepancies between conceptualizations and actual practice. Data from multiple sources detail issues in fidelity to family-centered values and needs and risks experienced by siblings of children with severe emotional disturbance and their caregivers. This discussion provides a springboard for policy recommendations to strengthen family support programming and enhance family-centered care, from modifying funding streams such that systems extend their reach beyond children with full-blown, diagnosable problems (those meeting standards of "medical necessity), to supporting prevention and early intervention initiatives that address families as targets for intervention. Recommendations include ensuring that communities with SOC funding address the needs of families; broadening Medicaid rules and definitions; expanding the range of reimbursable activities and services; and increasing funding for evaluating family-centered care models and family support programming. 相似文献
