The aim of this study was to examine the self‐monitoring of weight on a daily basis over a long period of time in order to understand the process of weight regain. An obese female client measured her weight every morning over a period of 10 years. The subject made a total of 2081 weight measurements. Thus, her weight was measured on 67% of all possible days. After the initial weight loss a pattern of gradual weight gain was observed. The subject gained weight during August and September, and at the end of December, in particular. Furthermore, her weight increased slightly at the weekends. This case study highlights the advantage of self‐monitoring of weight on a daily basis. Individual patterns of weight change possibly associated with season and weekly variation may be crucial when obese subjects try to maintain their weight after weight loss. However, it may take several months or even years to detect the weekly and yearly rhythms or other patterns in the data. Thus, self‐control of weight is problematic, since patterns in the weight regain process are difficult to detect. This may be one reason why self‐control of weight is so difficult. 相似文献

In this study we aim to increase our understanding of leadership in anaesthesia teams by investigating the relationship between substitutes for leadership, leadership behaviour, and team performance in situations with varying levels of routine and standardization. The present study relied on video recordings of 12 anaesthesia teams in a simulated setting with the occurrence of a nonroutine event. Clinical team performance was measured by the speed of adequate team reaction to this event. The leadership behaviours observed were coded either as content oriented (e.g., information transmission) or structuring (e.g., assigning tasks). Results showed that leadership behaviour changed depending upon the level of routine of a situation, the degree of standardization, and, to some extent, on the experience of team members. Leadership tends to be positively related to team performance during nonroutine and low standardized situations but negatively related to team performance in routine and highly standardized situations. Furthermore, leadership is only slightly related to team member experience. This study improves our understanding of influences of substitutes for leadership on successful leadership behaviour in anaesthesia teams. The findings also lead to suggestions for both further research and the enhancement of team leadership in critical care. 相似文献

We explored whether teams develop shared perceptions regarding the quantity and quality of information and the extent of participation in decision making provided in an environment of continuous change. In addition, we examined whether change climate strength moderated relationships between change climate level and team outcomes. We examined relationships among aggregated change information and change participation and aggregated team outcomes, including two role stressors (i.e., role ambiguity and role overload) and two indicators of well-being (i.e., quality of worklife and distress). Questionnaires were distributed in an Australian law enforcement agency and data were used from 178 teams. Structural equation modelling analyses, controlling for a marker variable, were conducted to examine the main effects of aggregated change information and aggregated change participation on aggregated team outcomes. Results provided support for a model that included method effects due to a marker variable. In this model, change information climate was significantly negatively associated with role ambiguity, role overload, and distress, and significantly positively associated with quality of worklife. Change participation climate was significantly positively associated with quality of worklife. Change climate strength did not moderate relationships among change climate level and team outcomes. 相似文献

Based on the insight that culture shapes resistance to change in an organization, and the recognition that cultures of organizations are embedded in a broader societal culture, this study seeks to provide empirical evidence on how societal-based cultural understandings and values within an organization serve as a source of resistance to change among employees. The study is based on a case study of a medium-sized Turkish company. The study shows how certain managerial decisions toward a professionally running organizational design are difficult to implement due to societal-based patterns of understandings and meaning systems gathered around status, hierarchy, and emotion-based (personalized) relations in the company. 相似文献

This study identified temporal conditions when membership change may enhance or diminish team functioning. Using a longitudinal repeated measures design surveying 41 R&D teams, this study examined whether team tenure moderated the relationship of membership change with open discussion and team performance. The results illustrated that increasing membership change was positively associated with both open discussion and team performance for newly formed teams, whereas this association was negative for long-serving teams. Thus, what matters is not so much whether a team's membership changes but rather whether the team's longevity supports or impedes adaptation to personnel changes. 相似文献

Commitment to change is considered the glue that binds people and change goals. Still, few studies have explored how employees develop their commitment to organizational change. The present study examined the relationship between supervisor competence and support, and employee's commitment to change. Participants were 210 full-time employees from two public organizations that had recently faced major change interventions resulting from governmental directives. As predicted, perceived supervisor support fully mediated the positive relationship between competence and affective and normative commitment to change. On the other hand, supervisor competence was negatively related to continuance commitment to change. These findings illustrate how supervisors can shape employees' reactions to change. 相似文献

Empirical research on the effects of functional diversity on team innovation has yielded largely inconsistent results, showing positive, negative, as well as nonsignificant effects. For capitalizing on the positive potential inherent in functionally diverse teams, opening the black box between cross-functionality and team innovation by analysing mediating and moderating processes thus seems to be highly relevant. In this article, task and relationship conflicts are introduced as mediators of functional diversity and team innovation. Within this framework, transformational leadership is discussed as a moderator. It will become apparent that the role of transformational leadership in fostering the innovativeness of cross-functional teams is rather ambiguous. The discussed mediators and the moderator transformational leadership are integrated into a comprehensive framework and propositions for future research are derived. 相似文献

The aim of this study was to explore two of the mechanisms by which transformational leaders have a positive influence on followers. It examined the mediating role of follower's leader and group identification on the associations among different transformational leader behaviours and follower job satisfaction and supervisor-rated job performance. One hundred and seventy-nine healthcare employees and 44 supervisors participated in the study. The results from multilevel structural equation modelling provided results that partially supported the predicted model. Identification with the leader significantly mediated the positive associations between supportive leadership, intellectual stimulation, personal recognition, in the prediction of job satisfaction and job performance. Leader identification also mediated the relationship between supportive leadership, intellectual stimulation, personal recognition, and group identification. However, group identification did not mediate the associations between vision leadership and inspirational communication, in the prediction of job satisfaction and job performance. The results highlight the role of individualized forms of leadership and leader identification in enhancing follower outcomes. 相似文献

Building on an interactionist approach, the present study investigated the moderating role of two task design characteristics, namely task autonomy and feedback from job, in the relationship between dispositional resistance to change and innovative work behaviour. Consistent with a trait activation perspective, it was specifically hypothesized that dispositional resistance to change would have a stronger, positive association with innovative performance when autonomy and feedback were high than when they were low. In a sample of 270 employees from the public sector, task autonomy was found to significantly interact with both composite resistance to change and with three of the four dimensions (routine seeking, short-term thinking, and emotional reaction). Simple slope analyses specifically revealed that individuals high in short-term thinking and emotional reaction exhibited positive relationships with innovative behaviour only in the case of high task autonomy, whereas in the case of low autonomy the relationship was nonsignificant. Furthermore, feedback from job was found to moderate the relationship between overarching dispositional resistance to change, short-term thinking, and emotional reaction, on one hand, and innovative performance, on the other, such that a positive and significant association emerged only in the case of high feedback. 相似文献
