It rises massive and magnificent above Salisbury Plain. The extraordinary monoliths of Stonehenge leave us as impressed today as ever—and as baffled. Archaeologists argue about how it was made. Can statisticians tell the answer? Chris Jones thinks they can be of considerable assistance. 相似文献

A data base that provides a multivariate statistical history for each of a number of individual entities is called a pooled cross-sectional and time series data base in the econometrics literature. In marketing and survey literature the terms panel data or longitudinal data are often used. In management science a convenient term might be management data base. Such a data base provides a particularly rich environment for statistical analysis. This article reviews methods for estimating multivariate relationships particular to each individual entity and for summarizing these relationships for a number of individuals. Inference to a larger population when the data base is viewed as a sample is also considered. 相似文献

Community-based rehabilitative exercise programs might be an effective means to improve functional outcomes for hip-fracture patients. The purpose of this study was to evaluate the effectiveness of a community exercise program (CEP) for older adults recovering from hip fracture. Twenty-five older adults (mean age 80.0 +/- 6.0 years; 24 women; 71 +/- 23 days post-hip fracture) participated in this pilot study (17 exercise, 8 control). The CEP involved functional stepping and lower extremity-strengthening exercises. Control participants received only standard outpatient therapy. Measures of functional mobility, balance confidence, falls efficacy, lower extremity strength, and daily physical activity were evaluated at baseline and at 16 weeks. Improvements for self-reported physical activity, mobility, balance, and knee-extensor strength were observed for the CEP group. This study demonstrated that a CEP is beneficial for community-dwelling older adults post-hip fracture. 相似文献

Both labor and management often have a lawyer present their case at an arbitration hearing. This paper investigates whether
the probability of obtaining a favorable arbitration outcome was related to the use of legal counsel. An analysis of 1,284
Canadian non-discipline/discharge cases revealed that a party was more likely to receive a favorable award when it had legal
representation and the other side did not. However, there was no difference in win rates when the outcomes of cases in which
both parties used lawyers were compared with those in which neither side was represented by legal counsel.

This prospective longitudinal study examined the unique and combined effects of neighborhood characteristics on parental behaviors in the context of more distal and more proximal influences. With a sample of 368 mothers from high‐risk communities in 4 parts of the United States, this study examined relations between race (African American or European American), locality (urban or rural), neighborhood characteristics, family context, and child problem behaviors, and parental warmth, appropriate and consistent discipline, and harsh interactions. Analyses testing increasingly proximal influences on parenting revealed that initial race differences in warmth and consistent discipline disappeared when neighborhood influences were considered. Although generally culture and context did not moderate other relations found between neighborhood characteristics, family context, and child behaviors, the few interactions found highlight the complex influences on parenting. 相似文献

The purpose of this paper was to find out whether the relationship between type of contact with agency and/or child in foster care and average number of contacts over time makes any difference in length of stay in foster care. Four types of contacts were examined: Family—Agency, Family Initiated—Agency, Social Worker—Initiated, and Family—Child. Results indicated that there were critical numbers for each contact type found to be statistically significant that would tend to reduce the length of the child's stay in foster care. The importance of contact during the first month of placement was emphasized. 相似文献

No single program seems adequate to serve a highly complex adolescent runaway and homeless youth population. A service program must have many components with each part addressing the needs of a specific and different population. This paper presents a typology of runaway behavior which has three categories. These categories distinguish among runaway and homeless youth by reference to their family situation, psychological characteristics, and length of time out of home. The implications for intervention that follow from these categories are discussed.former Bush fellow at the University of California, Los Angeles. 相似文献

This article uses a case study of the Niagara Movement, which functioned from 1905–1910, to demonstrate that the use of prosopography (collective biographies) is a propitious methodological tool, particularly for those interested in the social-psychological analysis of movement actors within networks. I present a prosopography of the founders of the Niagara Movement. Learning more about the identity of political actors provides clues to the ways strategic choices are made and how collective action frames are developed. The prosopography of the Niagara Movement also provides theoretical insights into discursive processes that are often lost in studies of long movement trajectories. I analyze potential explanations for the absence of organizations such as the Niagara Movement from the civil rights canon, and, through an analysis of talk as a resource for mobilization, pinpoint directions for future researchers interested in micro theories of mobilization. 相似文献
