Four experiments explored the processes that bridge between referent selection and word learning. Twenty‐four‐month‐old infants were presented with several novel names during a referent selection task that included both familiar and novel objects and tested for retention after a 5‐min delay. The 5‐min delay ensured that word learning was based on retrieval from long‐term memory. Moreover, the relative familiarity of objects used during the retention test was explicitly controlled. Across experiments, infants were excellent at referent selection, but very poor at retention. Although the highly controlled retention test was clearly challenging, infants were able to demonstrate retention of the first 4 novel names presented in the session when referent selection was augmented with ostensive naming. These results suggest that fast mapping is robust for reference selection but might be more transient than previously reported for lexical retention. The relations between reference selection and retention are discussed in terms of competitive processes on 2 timescales: competition among objects on individual referent selection trials and competition among multiple novel name–object mappings made across an experimental session. 相似文献

This study examines the friendship patterns of older adults living in rural and urban areas. The sample consisted of 132 urban adults and 126 rural adults, 65 years of age and older. Respondents were randomly selected and interviewed in their own homes. While both groups were involved in joint social activities and helping behaviors with their friends, there was a distinction in the type of involvement according to geographical location.Karen Roberto is Assistant Professor and Coordinator of the Gerontology Program at the University of Northern Colorado. Her current research interests include women's health issues in aging and older people's involvement with informal support networks. Dr. Roberto holds a Ph.D. in Human Development from Texas Tech University.Jean Pearson Scott is Associate Professor in the Department of Human Development and Family Studies at Texas Tech University. Dr. Scott earned her Ph.D. from the University of North Carolina at Greensboro and is currently conducting research on Alzheimers Disease in the family and the rural elderly.This is a revised version of a paper presented at the Families and Close Relationships: Individuals in Social Interaction Conference, Lubbock, TX, February, 1982.This study was supported by a grant from AARP Andrus Foundation and the Institute for University Research, College of Home Economics, Texas Tech University, Lubbock, Texas 79409. 相似文献

The authors describe a medical center-based randomized trial aimed at determining the feasibility and effectiveness of partnering patients and primary-care providers with an exercise health counselor. Study participants included 165 veterans age 70 years and older. The primary end point was change in physical activity at 3 and 6 months comparing patients receiving high-intensity physical activity counseling, attention control counseling, and usual care after receiving standardized clinic-based counseling. We noted a significant Group x Time interaction (p = .041) for physical activity frequency and a similar effect for caloric expenditure (p = .054). Participants receiving high-intensity counseling and usual care increased physical activity over the short term, but those with usual care returned to baseline by the end of the study. The intervention was well received by practitioners and patients. We conclude that partnering primary-care providers with specialized exercise counselors for age- and health-appropriate physical activity counseling is effective. 相似文献

ABSTRACTGrandfamilies, family structures in which grandparent(s) co-reside with and assume a primary caregiving role for at least one grandchild, are increasingly common in the United States. This qualitative, exploratory study, informed by family communication patterns theory (FCPT), illuminated the reported communication beliefs and practices of grandparents who serve as primary caregiver to at least one grandchild. Hybrid thematic analysis, combining FCTP with inductive analysis, was used to analyze 21 semi-structured interviews with grandparents. Results yielded four themes describing grandparents’ reported communicative practices: creating opportunities for listening and dialogue, talking about emotion, emphasizing openness, and allowing questioning; and three themes describing the impact of second-chance parenting: increased resources, acquired wisdom, and matured emotionally. Implications for grandfamily communication research in light of hybrid analyses and FCPT are discussed. 相似文献

AbstractObjective: The current study aims to validate the PERMA-Profiler, a well-known well-being measure, among a sample of student veterans. Participants: A sample of 205 student veterans were recruited from universities across the United States. Method: Cross-sectional research design was used in this study. Measurement structure of the PERMA-Profiler was evaluated using exploratory factor analysis (EFA). Convergent, divergent, and criterion-related validity was tested using Pearson correlation coefficients and Kruskal-Wallis test. Results: The EFA results yielded a two-factor solution for student veterans. Factors are named as emotional character strengths and performance character strengths. Conclusions: The PERMA-Profiler is a multidimensional scale with good reliability and acceptable levels of convergent, divergent, and criterion-related validity. The PERMA-Profiler can help researchers and practitioners better gauge well-being in student veterans. Implications will be discussed. 相似文献

AbstractObjective: The purpose of this study was to explore differences in oral health among students by military service status in postsecondary settings. Participants: Secondary data were obtained from the American College Health Association’s 2011–2014 National College Health Assessment II. Method: Demographic characteristics of the study sample were explored by calculating frequencies and percentages by military service status. Research questions were explored with maximum likelihood multiple logistic regression. Results: Service member and veteran students are at greater risk for neglecting health behaviors associated with positive oral health, including that they were less likely to get dental exams and that those who deployed in the past were the least likely to be practicing good oral health. Conclusions: The results suggest that improving oral health will contribute to improving health and mental health outcomes in this population, and provide important information for health specialists working with service members and veterans on college campuses. 相似文献

ABSTRACTThe optimal learner for prediction modeling varies depending on the underlying data-generating distribution. Super Learner (SL) is a generic ensemble learning algorithm that uses cross-validation to select among a ‘library’ of candidate prediction models. While SL has been widely studied in a number of settings, it has not been thoroughly evaluated in large electronic healthcare databases that are common in pharmacoepidemiology and comparative effectiveness research. In this study, we applied and evaluated the performance of SL in its ability to predict the propensity score (PS), the conditional probability of treatment assignment given baseline covariates, using three electronic healthcare databases. We considered a library of algorithms that consisted of both nonparametric and parametric models. We also proposed a novel strategy for prediction modeling that combines SL with the high-dimensional propensity score (hdPS) variable selection algorithm. Predictive performance was assessed using three metrics: the negative log-likelihood, area under the curve (AUC), and time complexity. Results showed that the best individual algorithm, in terms of predictive performance, varied across datasets. The SL was able to adapt to the given dataset and optimize predictive performance relative to any individual learner. Combining the SL with the hdPS was the most consistent prediction method and may be promising for PS estimation and prediction modeling in electronic healthcare databases. 相似文献

ABSTRACTThis study explores living conditions of people in Senegalese fishing communities in relation to environmental change and unregulated fishing by foreign boats, weakening local opportunities and increasing forced migration of youth, creating problems for the future development of local fishery communities. It employs a postcolonial perspective and analyzes data collected through interviews with individuals from Senegalese fishing communities, social workers and relevant documents. The results show local reactions based on alliances between social workers and local community members to overfishing and the need for national and global structural changes. It is argued that EU’s fishing agreements with Senegalese government is one of the reasons behind youths’ forced migration to EU countries and that the betterment of the living conditions of fishery communities in Senegal requires not only already emerging alliances between social workers and local community members, but also national and global structural changes to protect Africa’s fishing communities and local fisheries. 相似文献

This paper argues that at a time when policy guidance urged closer collaboration and joint working between health and social services, the long-established cultural and professional gaps were widening and deteriorating. Drawing on data from four research sites, the paper argues that the deterioration was rooted principally in practitioners' preoccupations with changes within their own organizations and daily work, resulting from a major period of change in both health and social services, which, ironically, was at the expense of the joint working which the "Caring for People" reforms required. As the policy environment changes again, under the Labour government, it is likely that health and social care practitioners will be working within further organizational turbulence and change. It will be crucial that those changes are managed in such a way that they avoid the very real danger of compounding the problems which our respondents identified. 相似文献
