The purpose of this article is to describe how one university counseling center went about the process of changing its management style and subsequent service delivery. In a relatively short period of time the center went from the traditional director-staff relationship to a collective governance process. This shared governance process is based on the assumptions that the product of collective planning, shared responsibilities, and group decision making enhance morale, creativity, and productivity. As a result of the arduous tasks involved in the shift of administrative styles, the center has established group accountability, collective decision making, open communication, and total group program development. For this center's staff the transition to nonauthoritarian governance has been both stimulating and exciting. However, the process of change involves high risks, continual cooperation, and a climate of support. Without these ingredients the potential for creative management will be sharply reduced.  相似文献

Objective. To further understanding of the stability and variability in maternal behavior across tasks, time, and sibling pairs. Design. Mothers (a total of 451) were observed separately in interactions with two of their children across two tasks and three time points. Independent observers rated responsive and negative maternal behaviors. Results. Moderate to large correlations across tasks (responsivity = .51; negativity = .41), time points (responsivity = .40; negativity = .38), and siblings (responsivity = .56; negativity = .49) were found. Although these correlations indicate significant stability (i.e., consistency) of maternal behavior, they also indicate variability, with unexplained variance ranging from 69–84% for responsivity and 75–86% for negativity. Conclusions. Proportions of maternal behavior across tasks, time, and siblings can and cannot be accurately predicted given examination of maternal behavior in a comparable task, later time point, or sibling. The current study underscores the importance of considering both stability and variability as equally critical components for understanding maternal behavior.  相似文献

This paper describes an Australian sample of 78 single and 107 partnered mothers who entered or re‐entered tertiary study as mature age students. 27% were early school leavers; of those who had matriculated, early marriage and/or early pregnancy were major reasons for non‐continuance with study, and this was particularly the case among those who subsequently became single mothers. Both partnered and single were enrolled in more traditionally female courses of study than were younger female students attending the same institutions. Some four‐fifths of the sample felt they were managing their time, work, relationships, finances and overall coping poorly or very poorly. However their academic performance was well above average. The single mothers felt they were coping rather better than the married, especially with regard to money (despite being poorer), relationships and time. Overall satisfaction with university life was very high, with the main benefits reported by both single and partnered mothers being self‐esteem, knowledge, intellectual interests and intelligence. Career benefits and financial potential were mentioned less often as main benefits and only slightly more frequently by the single mothers. The question is raised of whether mature age women students, as well as female school leavers, should be encouraged to enter non‐traditional courses of study.  相似文献

The study reported herein was designed to use eye movement data, collected during solution of complex figural analogies, to test the premise that enhanced feedback mechanisms and opportunities for dual coding of figural stimulus information result in the allocation of an increased percentage of information-processing resources to rule application activities. Subjects were given items from the Advanced Progressive Matrices under elaborated feedback, subject verbalization, or standard procedures. Results indicate that elaborative testing conditions, involving elaborated feedback or subject verbalization, enhance the rule-governed nature of information processing during inductive reasoning by augmenting feedback and dual coding.  相似文献

A survey was conducted in eight secondary schools located in two watersheds in Gujarat and Rajasthan (semi-arid region of India) to assess students’ perceptions about groundwater scarcity issues and the impact of the scarcity on their educational opportunities. Survey responses to a detailed questionnaire by a cohort of students in both watersheds; school attendance records of year 8 class students (13–14 years old) and responses gathered via a socio-economic survey involving 500 families in the study area were used in the study. In both watersheds, >90% students identified groundwater scarcity as a major issue. Required to work at home or farm, about 65% students in Gujarat and 60% in Rajasthan missed school for up to 2 days/month; and a smaller proportion (~ 30%) missed schools for 4 or more days/month. School absenteeism was found to be linked with gender; female students missed schools more frequently than their male counterpart. The school attendance records in Rajasthan showed that the frequency of female students missing schools for 5 or more days/month was on an average 2–10 times greater than that for males. The gender difference in absenteeism in all schools was statistically significant (P?<?.018**). The study highlighted that groundwater scarcity in the study area, and consequent demand on their time for household work including fetching drinking water are contributing factors towards limiting their educational and economic opportunities. Groundwater scarcity can be one of the key factors that can limit inclusiveness and empowerment of women and need to be considered in policy-making.  相似文献
