This study examined the possible selves, goals, and perceptions of “time left” of older adults soon after they entered a life plan community as independent living residents. There has been little research regarding the effect of this life transition on older adults’ self-concept, hopes, and fears. Eighteen residents participated in one-hour personal interviews about their reasons for moving, their possible selves, goals, and perception of time left. Time left was measured in two ways: residents were asked to estimate the number of years they had left and were also asked to mark, on a novel visual analogue measure, how “limited” or “expanded” their time left felt to them. Residents were found to have an average of 6.18 possible selves in total, with more hoped-for possible selves (m = 4.39) than feared possible selves (m = 1.78). The majority of the goals were maintenance goals, followed by self-improvement goals and then avoidance goals. Residents estimated that they would live for 11.64 more years, and the majority reported that this felt like “a lot of time.” Based on their responses to the novel visual analogue measure of time left, two-thirds of the participants reported that their time left felt “expanded” rather than “limited.” Consistent with predictions based on socioemotional selectivity theory, participants with longer subjective life expectancies reported more self-improvement goals and more hoped-for selves. Participants identified more possible selves than documented in previous studies, including almost twice as many hoped-for possible selves.  相似文献

This study examined the association of census level, observational, and parent-reported neighborhood characteristics on the verbal and behavioral competencies of a national sample of Canadian preschoolers (N = 3,350). Children's verbal ability scores were positively associated with residing in neighborhoods with affluent residents and negatively associated with residing in neighborhoods with poor residents and in neighborhoods with low cohesion, even after controlling for family socioeconomic factors. Behavior problem scores were higher when children lived in neighborhoods that had fewer affluent residents, high unemployment rates, and neighborhoods with low cohesion, after controlling for family socioeconomic factors. These findings are discussed in light of neighborhood studies of children in the United States in the mid-1990s.  相似文献

We examined how raters and tasks influence measurement error in writing evaluation and how many raters and tasks are needed to reach a desirable level of .90 and .80 reliabilities for children in Grades 3 and 4. A total of 211 children (102 boys) were administered three tasks in narrative and expository genres, respectively, and their written compositions were evaluated in widely used evaluation methods for developing writers: holistic scoring, productivity, and curriculum-based writing scores. Results showed that 54 and 52% of variance in narrative and expository compositions were attributable to true individual differences in writing. Students’ scores varied largely by tasks (30.44 and 28.61% of variance), but not by raters. To reach the reliability of .90, multiple tasks and raters were needed, and for the reliability of .80, a single rater and multiple tasks were needed. These findings offer important implications about reliably evaluating children’s writing skills, given that writing is typically evaluated by a single task and a single rater in classrooms and even in some state accountability systems.  相似文献

Parenting practices (problem-solving and disciplinary styles) in a sample of 99 young, low-income, African-American multigenerational families were examined, using home-based observations of grandmothers and young mothers (mean age at first birth; 18.3; range = 13.3 to 25.5), interacting separately with 3-year-old children. A risk and resilience approach was applied in studying African-American families' behavior in harsh social contexts, and included a consideration of the role of kin, shared child rearing between mothers and grandmothers, coresidence, and adolescent parenthood. Mothers and grandmothers did not differ in the mean level of the quality of their parenting practices. Similarly, few significant correlations in parenting quality across generations were evident, and these primarily involved negative dimensions of parenting between younger childbearers and grandmothers. No main effect of mothers' age at first birth on mothers' parenting was found. In contrast, there was a main effect of grandmother coresidence on both mothers' and grandmothers' parenting, which was negative. Moreover, the interaction between coresidence and mothers' age at first birth indicated that multigenerational families most likely to provide positive parenting were those where older mothers did not reside with the grandmother. Yet, in families with very young mothers, coresiding grandmothers showed higher quality of parenting than did non-coresiding grandmothers.  相似文献

225 children (ages 4 to 8, 103 girls, 37.5% Mexican-American) participated, reporting who provides support, frequency of receiving different types of support, and satisfaction with support received. These reports were subjected to factor analyses and results did not fit a prior conceptualization. Exploratory factor analyses resulted in a three factor solution that was both more interpretable and the solutions were more similar for reports of frequency of receiving support and satisfaction. A total of six subscale scores were computed, three each for the frequency and the satisfaction items, which were subsequently labelled: informational/emotional, recreational, and practical support. Analyses of the empirically derived subscale scores suggested that young, pre- and early elementary school-aged children responded to questions about their social support in reasonably reliable and valid ways. Significant correlations with indices of perceived competence and acceptance resulted. Remarkably little is known about young children's perceptions of their social worlds, or specifically the nature of support they think is available or that they actually receive. These data suggest that gathering this information from the children themselves is feasible. Ultimately such information should be critical for the design and evaluation of early childhood curricula instructing children about social relations generally, and specifically, who they can turn to for support.  相似文献

This study examines the process of change among grade 4 teachers (students aged 9–10 years) who participated in a yearlong Teacher Quality Grant innovation program. The concerns-based adoption model (CBAM), which informed the design and implementation of the program, was used to examine the process of change. Two questions guided the investigation: (1) How did teachers’ concerns about and levels of use of the innovation evolve during the course of the project? (2) What changes in teachers’ perceptions and practices arose as a result of the innovation? Results showed that several of the teachers’ concerns evolved from self/task toward impact. With continued support, several participants achieved routine levels of use, which they sustained beyond the project.  相似文献

Based on literature from the domains of organization science, marketing, accounting, and management information systems, this review article examines the theoretical basis of the information overload discourse and presents an overview of the main definitions, situations, causes, effects, and countermeasures. It analyzes the contributions from the last 30 years to consolidate the existing research in a conceptual framework and to identify future research directions.  相似文献

This study used data from the Panel Study of Income Dynamics and its 1997 Child Development Supplement to examine how family income matters for young children's development. The sample included 753 children who were between ages 3 and 5 years in 1997. Two sets of mediating factors were examined that reflect two dominating views in the literature: (1) the investment perspective, and (2) the family process perspective. The study examined how two measures of income (stability and level) were associated with preschool children's developmental outcomes (Woodcock-Johnson [W-J] Achievement Test scores and the Behavior Problem Index [BPI]) through investment and family process pathways. Results supported the hypothesis that distinct mediating mechanisms operate on the association between income and different child outcomes. Much of the association between income and children's W-J scores was mediated by the family's ability to invest in providing a stimulating learning environment. In contrast, family income was associated with children's BPI scores primarily through maternal emotional distress and parenting practices. Level of income was associated with W-J letter-word scores and income stability was associated with W-J applied problem scores and BPI, even after all controls were included in the models.  相似文献

This case study describes the efforts of librarians to integrate mobile devices, collaboration tools, and resources into a School of Medicine third-year pediatric clerkship. Additional class emphasis is on evidence-based searching and journal article evaluation and presentation. The class objectives ensure that students are comfortable with mobile devices and collaboration tools. Over the eight-year history of the course, student acceptance of the mobile devices used diminished as the devices aged, necessitating the evaluation and selection of new technologies. Collaboration tools and mobile applications employed in the course evolved to accommodate curriculum changes.  相似文献
