Factors That Influence Willingness to Help the Homeless

Homelessness is an ongoing challenge for many families and individuals. Many struggle to meet their basic needs for food, clothing and shelter. Unfortunately, we know very little about the people who directly help homeless people meet these needs. The present study examines the relationships between empathy, religion, household income, political orientation, gender, race, and people's expressed willingness to assist the homeless. Results demonstrate a strong and consistent link between empathy and willingness to help. Moderately consistent associations are found for religion and race. Limitations, suggestions for further research, and for practical application are discussed.     

The effect of guided relaxation and exercise imagery on self-reported leisure-time exercise behaviors in older adults

The purpose of this study was to examine the effects of a 6-wk intervention that used guided relaxation and exercise imagery (GREI) to increase self-reported leisure-time exercise behavior among older adults. A total of 93 community-dwelling healthy older adults (age 70.38 ± 8.15 yr, 66 female) were randomly placed in either a placebo control group or an intervention group. The intervention group received instructions to listen to an audio compact disk (CD) containing a GREI program, and the placebo control group received an audio CD that contained 2 relaxation tracks and instructions to listen to music of their choice for 6 wk. Results revealed that listening to a GREI CD for 6 wk significantly increased self-reported leisure-time exercise behaviors (p = .03). Further exploration of GREI and its effects on other psychological variables related to perceived exercise behaviors may substantiate its effectiveness.     

Effects of Sexually Transmitted Infection Status,Relationship Status,and Disclosure Status on Sexual Self-Concept

Research has indicated that having a sexually transmitted infection (STI) such as genital herpes and genital human papilloma virus (HPV) can have a negative impact on an individual's sexuality. The current study was designed to evaluate the effect of STI status, relationship status, and disclosure status on various dimensions of sexual self-concept. A questionnaire that evaluated the above variables was completed by 117 individuals with genital herpes, 82 individuals with HPV, and 75 individuals with no STI. The results demonstrated that having herpes or HPV had a significant negative impact on aspects of sexual self-concept. It does not appear that an individual's relationship status is a factor associated with the impact of having an STI on the sexual self-concept. Respondents who had disclosed their STI to their partners, however, had significantly more positive feelings about aspects of their sexual self-concept than those who had not disclosed their STI to their partners. The implications of these research findings for health practitioners are discussed.

He then explains the measures which are taken to plan, control, and research the use of personnel. He deals in detail with the development of a computer based information system, attempts to determine the cost effectiveness of manpower, and the use of the Behavioural Sciences in a positive effort to shape personnel relations in the company. Finally, he mentions a number of changes which are likely to influence personnel strategy in the future.     

Toward an Epidemiology of Safety and Security Risks: An Organizational Vulnerability Assessment in International Airports

International airports are complex sociotechnical systems that have an intrinsic potential to develop safety and security disruptions. In the absence of appropriate defenses, and when the potential for disruption is neglected, organizational crises can occur and jeopardize aviation services. This investigation examines the ways in which modern international airports can be “authors of their own misfortune” by adopting practices, attitudes, and behaviors that could increase their overall level of vulnerability. A sociotechnical perspective, the macroergonomic approach, is applied in this research to detect the potential organizational determinants of vulnerability in airport operations. Qualitative data nurture the case study on international airports produced by the present research. Findings from this study highlight that systemic weaknesses frequently reside in areas at the intersection of physical, organizational, and social spaces. Specific pathways of vulnerability can be drawn across these areas, involving the following systemic layers: individual, task, tools and technology, environment, and organization. This investigation expands the existing literature on the dynamics that characterize crisis incubation in multiorganization, multistakeholder systems such as international airports and provides practical recommendations for airport managers to improve their capabilities to early detect symptoms of organizational vulnerability.     

Receptivity to Change in a General Medical Practice

In this paper, Pettigrew, Ferlie and McKee's concepts of receptive and non receptive contexts for change are examined using data from an evaluation study of a general medical practice implementing a Personal Medical Services Pilot between 1998 and 2001. Four questions concerning the applicability, associatedness, temporality and dynamism of the eight factors Pettigrew et al. identified as constitutive of receptivity are used in the analysis, which extends the original model through an operationalization yielding 21 ‘focal questions’. Although the process of change at the fieldwork site was stalled, the receptivity model is shown to have been a useful tool in identifying the factors blocking change. The analysis shows that when the eight factors are conceptualized in terms of the strength, direction and continuity of their influence, the receptivity metaphor provides a distinctive tool for the analysis of change. The paper concludes that further refinement of the model could provide a basis for the derivation of change management typologies.     

The bias of the mle of box's degrees of freedom correction factor for correlation in anova

Approximate expressions for the mean and variance of the MLE of Box's 2-way ANOVA degrees of freedom factor are given for the case when the usual F test for column effects is appropriate even though there is correlation across columns. A simulation study is performed showing the approximations are good for a variety of numbers of rows and columns. The results confirm that the estimated degrees of freedom factor is badly biased when no factor at all should be used.     

Relationship between balance and gait stability in healthy older adults

Age-related adaptations during walking create a more stable walking pattern, which is less effective for forward progression and might be related to balance deficiencies. This study determined the relationship between walking stability and measures of balance in older adults. Seventeen older and 20 young adults performed the Berg Balance Test (BBT) and walked 10 m. Walking velocity (WV) and cadence were measured, and a gait-stability ratio (GSR) was calculated. Higher GSR indicated that a greater portion of the gait cycle was spent in double-limb support. Age-group comparisons established declines in BBT scores and WV and increases in GSR with age. Significant relationships were identified for BBT Item 12 (alternate stepping on a stool) with WV (r =.58, r(2) =.34) and GSR (r = -.74, r(2) =.54). The correlation of BBT Item 12 with GSR was stronger than with WV (p <.05). Results indicated a strong relationship between increased gait stability and decreased balance for a dynamic weight-shifting task. Therefore, GSR is a better indicator of balance deficits during walking than is WV alone.     

Work in unemployment - occupied or preoccupied? A review

This review explores the literature on the concept of work in unemployment and its relationship to health. A range of literature about the activities of unemployed people is reviewed and discussed with reference to three questions: What do unemployed people do?, What activities are associated with the health of unemployed people? and Do unemployed people work? From the literature, two groups of unemployed people are described: those who are characterised by active patterns of activity and those characterised by passive patterns. It is argued that the active group is psychologically healthier than the passive group. Concepts of work in both groups of unemployed individuals are presented, arguing that the active group seeks to replace employment with other work activities and that the passive group are engaged in work also, but that this presents as fret and preoccupation about their situation. These concepts of work are presented in the context of three major theoretical models of the personal impact of unemployment. Finally, implications for practice and directions for future research are suggested.
