The relationship between organizational citizenship behavior (OCB) and two organizational rewards—salary and promotion—was examined. Employee gender also was tested as a moderator. Data from 440 individuals employed in multiple settings indicated that individuals who reported engaging more frequently in OCB directed toward the organization (OCBO) also reported receiving more promotions. Further, results indicated that gender was a moderator such that the relationship between OCBO and promotion was stronger for males than for females. The results also revealed an interaction between OCB directed toward individuals (OCBI) and OCBO. Specifically, high OCBI and low OCBO related to lower promotion rates than did low OCBI and low OCBO. Results are discussed in terms of implications for individual career development.  相似文献

Previous reports have indicated a small, positive relationship between physical activity and cognition. However, the majority of research has focused on older adults, with few studies examining this relationship during earlier periods of the life span. This study examined the relationship of physical activity to cognition in a cross-section of 241 community-dwelling individuals 15-71 years of age with a task requiring variable amounts of executive control. Data were analyzed with multiple regression, which controlled for age, sex, and IQ. Participants reported their physical activity behavior and were tested for reaction time (RT) and response accuracy on congruent and incongruent conditions of a flanker task, which manipulates interference control. After controlling for confounding variables, an age-related slowing of RT was observed during both congruent and incongruent flanker conditions. However, physical activity was associated with faster RT during these conditions, regardless of age. Response accuracy findings indicated that increased physical activity was associated with better performance only during the incongruent condition for the older cohort. Findings suggest that physical activity may be beneficial to both general and selective aspects of cognition, particularly among older adults.  相似文献

Two theoretical perspectives (i.e., standpoint theory and the communication boundary management theory) were used to investigate the comments that 39 female information technology (IT) employees made during focus groups as they discussed issues related to workplace barriers and voluntary turnover. The revealed causal mapping method was used to analyze the women’s responses. Voluntary turnover decisions were influenced by work schedule flexibility, family responsibilities, work stress, job qualities, and lack of consistency in workplace policies. Perceived barriers to promotion were linked to lack of respect, ageism, stress, and work schedule flexibility. Differences emerged between explicitly stated and implicitly embedded responses. Women explicitly discussed issues consistent with previous IT research; however their implicit statements often addressed barriers not commonly linked with IT advancement and turnover concerns.  相似文献

Summer camps have been recognized as a valuable means of delivering services to children with chronic illnesses. Although these camps exist in abundance across the United States, they have been largely underrepresented in the clinical psychology literature. Particularly, there is a staggering discrepancy between the number of camps in existence and the number of published articles pertaining to the systematic evaluation of these camps. We outline the potential benefits of camping programs for children who are chronically ill, describe the importance of systematically evaluating them, and provide a model for this evaluative process. We describe an evaluation of a diabetes summer camp and present implications of this study for camp decision makers and clinical psychologists working in pediatric medical settings.  相似文献

For twenty years the Nuprl (“new pearl”) system has been used to develop software systems and formal theories of computational mathematics. It has also been used to explore and implement computational type theory (CTT)—a formal theory of computation closely related to Martin-Löf's intuitionistic type theory (ITT) and to the calculus of inductive constructions (CIC) implemented in the Coq prover.

This article focuses on the theory and practice underpinning our use of Nuprl for much of the last decade. We discuss innovative elements of type theory, including new type constructors such as unions and dependent intersections, our theory of classes, and our theory of event structures.

We also discuss the innovative architecture of Nuprl as a distributed system and as a transactional database of formal mathematics using the notion of abstract object identifiers. The database has led to an independent project called the Formal Digital Library, FDL, now used as a repository for Nuprl results as well as selected results from HOL, MetaPRL, and PVS. We discuss Howe's set theoretic semantics that is used to relate such disparate theories and systems as those represented by these provers.  相似文献

This qualitative study evaluated benefits and challenges of the occupation of owning a communal pet dog living permanently at an adult psychiatric rehabilitation facility. Twenty-three participants (12 staff, 11 clients) completed surveys, interviews, and focus groups. Data were analyzed through multiple coding, member checking, and triangulation. Three major themes emerged: (a) positive emotional experiences, (b) challenges of dog ownership, and (c) supporting engagement in meaningful occupation. While experiences of participant’s were broadly positive, challenges with adopting a dog in its puppy stage of development were acknowledged. A novel finding recognizing positive impacts on the well-being of staff was found.  相似文献

Praise and other forms of attention may not function as reinforcers for the behavior of children with autism. Previous research demonstrated that contingently pairing praise with reinforcers (response stimulus) can establish praise as a conditioned reinforcer. We evaluated a procedure for establishing praise as a generalized conditioned reinforcer (pair praise with four reinforcers) and compared it with a procedure to establish praise as a conditioned reinforcer (pair praise with one reinforcer). We compared the two conditions in a reversal design with “praise” and “no programmed consequence” conditions rapidly alternated after pairing phases. With three out of five participants with autism, responding in the “pair‐with‐four” condition showed higher levels of responding or more increasing trends compared with that in “pair‐with‐one” condition. We also replicated previous contingent pairing research with two participants in a multiple baseline across participants design. A limitation was the absence of manipulating motivating operations in assessing the efficacy of praise as a generalized conditioned reinforcer. Nevertheless, these data contribute to the research on establishing praise as a reinforcer, and we recommend directions for future research.  相似文献

Understanding the specific contexts where spirituality may or may not be helpful has been identified as a priority in spirituality and health research. The study aims were to clarify the helpfulness of spirituality and the interrelationships among transformation, spirituality, and forgiveness in this community-based group offered in a societal context of violence. Sixteen group participants from the Bahamas were selected and interviewed. Nine participants were female (56%); 75% identified as Black and 25% identified as White/Caucasian. NVivo 11 software was used. Transformation and spirituality themes were prevalent: themes related to prayer, group connection, and compassion were prominent. Selected spirituality themes were proximal to transformation themes, particularly forgiving others. The group process themes were closely linked to transformation themes. Participants noted that modelling by the group provided support for them to forgive and change. These findings may inform future efforts to intervene in communities experiencing violence and societal fragmentation.  相似文献

This paper analyzes the work of Christopher Southgate with a view toward interpreting his insights into the integrity of creation, redemption and theodicy in light of Saint Augustine's theology. Drawing on various contributions that Southgate has made, this paper seeks to establish parallels, connections and some agreement between his work and the great African bishop without papering over the obvious disagreements over the Fall, Original Sin, the premises of salvation and biblical hermeneutics.  相似文献
