Relationships of Job and Family Involvement, Family Social Support, and Work–Family Conflict with Job and Life Satisfaction

A model of the relationship between work and family that incorporates variables from both the work-family conflict and social support literatures was developed and empirically tested. This model related bidirectional work-family conflict, family instrumental and emotional social support, and job and family involvement to job and life satisfaction. Data came from 163 workers who were living with at least 1 family member. Results suggested that relationships between work and family can have an important effect on job and life satisfaction and that the level of involvement the worker assigns to work and family roles is associated with this relationship. The results also suggested that the relationship between work and family can be simultaneously characterized by conflict and support. Higher levels of work interfering with family predicted lower levels of family emotional and instrumental support. Higher levels of family emotional and instrumental support were associated with lower levels of family interfering with work. (PsycINFO Database Record (c) 2013 APA, all rights reserved)

Black-Hole Transients and the Eddington Limit

I show that the Eddington limit implies a critical orbital period P_crit(BH) = 2d beyond which black-hole LMXBs cannot appear as persistent systems. The unusual behaviour of GRO J1655-40 may result from its location close to this critical period.Comment: 3 pages, no figures; to appear in MNRA

The design and evaluation of a vibrotactile progress bar

We present an investigation into the use of Tactons to present progress information. Progress bars are common but must compete for screen space and visual attention with other visual tasks. We created a tactile progress indicator, encoding progress into a series of vibrotactile pulses. An experiment comparing the tactile progress indicator to a standard visual one showed a significant improvement in performance and an overall preference for the tactile display

Resilience–Recovery Factors in Post-traumatic Stress Disorder Among Female and Male Vietnam Veterans: Hardiness, Postwar Social Support, and Additional Stressful Life Events

Structural equation modeling procedures were used to examine relationships among several war zone stressor dimensions, resilience-recovery factors, and post-traumatic stress disorder symptoms in a national sample of 1,632 Vietnam veterans (26% women and 74% men). A 9-factor measurement model was specified on a mixed-gender subsample of the data and then replicated on separate subsamples of female and male veterans. For both genders, the structural models supported strong mediation effects for the intrapersonal resource characteristic of hardiness, postwar structural and functional social support, and additional negative life events in the postwar period. Support for moderator effects or buffering in terms of interactions between war zone stressor level and resiliencerecovery factors was minimal

Rationality of moduli of vector bundles on curves

The moduli space M(r,d) of stable, rank r, degree d vector bundles on a smooth projective curve of genus g>1 is shown to be birational to M(h,0) x A, where h=hcf(r,d) and A is affine space of dimension (r^2-h^2)(g-1). The birational isomorphism is compatible with fixing determinants in M(r,d) and M(h,0) and we obtain as a corollary that the moduli space of bundles of rank r and fixed determinant of degree d is rational, when r and d are coprime. A key ingredient in the proof is the use of a naturally defined Brauer class for the function field of M(r,d).Comment: 21 pages, Latex2e (with AMS packages

Understanding the role of local safety groups in managing safety practices between micro construction firms and principal contractors

Construction projects incorporate the input of a range of tradesmen and different sized firms, ranging from micro to large organisations. Working practices of micro construction firms are carried out in an informal manner while larger organisations tend to adopt more formal on-site management techniques. Many micro firms seek to develop long-term relationships with large principal contractors and a major strain on their relationships stem from the difference in safety management techniques they employ. Faced with a fundamental shift in their style of safety management, workers of micro construction firms must successfully negotiate this challenge. Against this background, records from the Health and Safety Executives show year on year reductions in accident and incident rates in the East Midlands, an indication that the safety practices on projects are being implemented more effectively. Some of this success has been attributed to the efforts of local safety groups, such as Nottinghamshire Occupational Safety and Health Association (NOSHA). As such, it is important that the interdependencies between large principal contractors and micro firms, and the role that safety groups such as NOSHA play in managing this relationship are better understood. This paper presents interviews conducted with some members of NOSHA. This is the first of two phases of empirical work. The roles that the members of the local safety group perform have been found to go beyond simply promoting safety awareness and safety knowledge on site. They have been found to help in conflict resolution among the various construction parties. Such practices help create a harmonious working environment and subsequently lead to long-term working relations
