Sex, age, season, and habitual physical activity of older Japanese: the Nakanojo study

The interactions of sex, age, season, and habitual physical activity were examined in 41 male and 54 female Japanese age 65-83 yr, using a pedometer/accelerometer that determined step counts and amounts of physical activity (<3 and >3 metabolic equivalents [METs]) throughout each 24-hr period for an entire year. All 3 measures were greater in men than in women. In women, age was negatively correlated with step count and activity <3 METs, but in men, it was correlated with step count and activity >3 METs. Irrespective of sex or age, all 3 activity variables were low in the winter, peaking in spring or autumn. In the summer, step counts matched the annual average, but durations of activity <3 and >3 METs were, respectively, longer and shorter than in other seasons. These findings have practical implications for those promoting physical activity for older adults.     

Effects of exercise training with weighted vests on bone turnover and isokinetic strength in postmenopausal women

The effects of 12 wk of exercise training using weighted vests on bone turnover and isokinetic strength were evaluated in postmenopausal women randomly assigned as exercisers (EX; n = 9) or controls (CON; n = 7). Training included 3 multimodal exercise sessions per wk wearing weighted vests. The vest load was progressively increased each wk to a maximum of 15% of body weight. Bone turnover was determined from resting levels of serum osteocalcin and NTx. Knee and ankle strength were measured at 60 degrees/s and 180 degrees/s using an isokinetic dynamometer. After 12 wk, NTx decreased by 14.5% (P 相似文献   

The Characteristics of Children with a Disability Looked After away from Home and their Future Service Needs

Correspondence to Professor Roy McConkey, School of Nursing, University of Ulster, Newtownabbey, N. Ireland BT37 0QB. E-mail: r.mcconkey{at}ulster.ac.uk Summary Little is known about the characteristics of children with disabilitieswho meet the British legal definition of ‘looked after’children. Data were obtained on 108 such children living withinone geographical area in Northern Ireland and who spent 90 daysor more in a 12-month period living away from the family home.However, this figure may under-estimate the numbers, given thedifficulties in tracking children aged over 14 years who wereadmitted to hospitals on a short- or long-term basis. The medianage of the children was 14 years; most had learning disabilitiesallied with challenging behaviours, communication difficulties,autism and some were technologically dependent. Many of theirfamilies experienced a range of problems. One-third of the childrenwere accommodated in various residential settings but half ofthese placements were in hospital or adult residential accommodation.However, there were marked differences in the services providedto this client group by the four provider agencies. Future serviceneeds included increased respite breaks for families and theprovision of both more residential placements and more appropriateaccommodation, especially for teenagers. The dilemmas in reconcilingthe need for local, but specialized, service provision are discussed.     

Gambling over the life course and treatment-seeking

The purpose of this study is to investigate change in gambling behaviours over the life course, and, correspondingly, the treatment-seeking behaviours of 86 people who met the criteria for at-risk (participants endorsing two to four items on the South Oaks Gambling Screen [SOGS]) and problem gamblers (participants endorsing five or more items on the SOGS) over the last five years. Data were obtained from informants during semi-structured interviews using Structured Clinical Interview for DSM-IV axis I and axis II disorders (SCID I and II), SOGS and treatment-seeking interviews. The results showed three groups of gambling behaviours over the life course. A first group started gambling early on and continued participating in recreational gambling until its participants were between 40 and 50 years of age, during which time they became problem gamblers. A second group transitioned from recreational gambling to problem gambling over a short period of time; its participants were aged between 40 and 50. Lastly, a third group which was exposed to gambling later on in life, mostly after retirement, developed gambling problems quickly. Psychopathology was prevalent in all groups, given that 98% suffered from a mental health problem during their life, and 62% within the last six months. Participants who made use of the services available mostly turned to medical and specialized mental services for brief periods, usually when in crisis. In terms of problem gambling, the results argue in favour of maintaining dedication toward treatment, especially in the presence of co-morbidity.     

Notebooks as Projects in a History Course

This article focuses on high school students' knowledge and notions of citizenship after taking the United States Citizenship and Immigration Services (USCIS) Naturalization Test. The students' test results and responses show emerging support for the need to make changes to the test as well as the students' limited conceptions of citizenship. In addition, this study's methodological benefits and challenges are discussed with implications for future research and practice.     

A cross‐cultural study of the phasic progression of self‐esteem in teen challenge

An attempt is made to analyze the effects of the Teen Challenge program in the self‐esteem of rehabilitants, and to determine if, indeed, any relationship exists. The importance of self‐esteem as a psycho‐social concept has emerged in recognition of man's needs for feelings of self‐worth. Central to this concept are the seminal formulations of White, Cooley, Coopersmith, Goffmann, and Harris. Additionally, Maslow's “hierarchy of needs” brings this concept into focus. Cooley notes that self‐concept emerges as a result of a series of interactions and appraisals of other people. The self‐concept, as it relates to self‐esteem, is also of major concern to the Teen Challenge program, the subject of this research. Teen Challenge is a therapeutic community seeking the resocialization of drug addicts, criminals, juvenile delinquents, prostitutes, alcoholics and other deviant types. This program is a three‐phase (orientation; training; re‐entry), one‐year residential program which uses the soteriological approach (conversation‐catharsis) as the starter‐mechanism to resocialization. According to a recent, federally funded, follow‐up study, 86 per cent of those who graduated from this program seven years previously had not recidivated. If indeed these statistics are valid, this would merit further research to determine variables significant to the resocialization process. This research assumes that self‐esteem is one such variable, though perhaps only one of many. It is further assumed that this would be low upon entry, and would progress consistently in a positive direction throughout one's stay in the program. Data was collected from centers in six different countries for a cross‐cultural comparison. To avoid contamination, all residents immediately upon entry into the Teen Challenge program in 1975 were tested using the Rosenberg “Self‐Esteem Scale.” Residents were tested again at the mid‐point of their stay using the S.E.S., and retested again when eligible for graduation one year later. Although an analysis of variance did not indicate a consistant increase in self‐esteem as hypothesized, low scores upon induction zoomed up in phase one, dipped slightly during the second phase, then resumed their climb in phase three, reaching an apex at the time of graduation. The over‐all trend for all centers, however, from low to high was highly significant. These results have heuristic potential.     

The Emergence and the Effects of Therapeutic Factors in Groups

ABSTRACT

This article explores the emergence of therapeutic factors in domestic violence men's group, as well as their effects on participants and the group. The authors conducted semistructured interviews with 72 men from groups in Quebec, after their fourth session. Thirty-eight of these men were met again, following their 16th session. A critical incident technique permitted us to identify various therapeutic factors. Three key factors are discussed: imparting information, hope, and cohesion. The authors found different processes influencing their development, particularly the roles of the worker, other members, and the group as a whole. These factors helped members meet their objectives and by their interdependency also contributed to group development. The authors made links with mutual aid and identified implications for research and practice.     

IASWG Standards for Social Work Practice with Groups: The Case of Quebec Practices

The International Association for Social Work with Groups (IASWG) proposes Standards of social group work that are intended to act as minimum standards that can be applied internationally. The aim of this article is to examine group work practices in Quebec in the light of IASWG Standards. To address this question, secondary analysis of existing data from a study undertaken in Quebec is presented. Results indicate that group work practices in Quebec tend to be rather structured (e.g., selection criteria, norms). The discussion shows that the IASWG Standards are useful for critically examining Quebec practices but also provides information that could contribute to the improvement of these Standards.     

Assessing the Potential Impact of the HIV-1 Epidemic on Orphanhood and the Demographic Structure of Populations in sub-Saharan Africa

Much of the debate on the demographic consequences of the HIV epidemic in sub-Saharan Africa has so far centred around the plausibility of population declines in areas where unprecendently high rates of population growth have recently been in evidence. In this article, the authors use a mathematical model, which combines epidemiological and demographic processes, to illustrate how, under a broad range of impacts on population growth, major changes in demographic features, such as the extent of orphanhood within populations, are likely to occur. At the same time, HIV epidemics are liable to cause significant shifts in the age and sex composition of affected populations, which may have important implications for the ways in which they are best able to cope with the increases in orphanhood, as well as those in infant, early childhood and adult mortality.
