Does whom you work with matter? Effects of referent group gender and age composition on managers' compensation.

Much research has examined gender and age effects on compensation, concluding that a wage gap exists favoring men and negative stereotypes against older workers persist. Although the effect of an employee's gender or age has been widely studied, little work has examined the impact of the demographic characteristics of a focal employee's immediate referent groups (e.g., subordinates, peers, or supervisors) on pay. The effect of the gender and age composition of a focal manager's subordinates, peers, and supervisor on the manager's compensation levels was investigated in a sample of 2,178 managers across a wide range of organizations and functional areas. After controlling for a number of human capital variables, results indicated that not only does a wage gap favoring men exist, but also managerial pay is lower when managers' referent groups are largely female, when subordinates are outside the prime age group, and when peers and supervisors are younger.

Effect of beta-glucan from oats and yeast on serum lipids

Heart disease is the leading cause of death in the U.S. One way to reduce the risk of developing the disease is to lower serum cholesterol levels by making dietary changes. In addition to reducing intake of total fat, saturated fat, and dietary cholesterol, serum cholesterol can be further reduced by added fiber, especially from sources rich in beta-glucan. In this review, two sources of beta-glucan are described; one source is oats and the other yeast. Their chemical structures and physical properties are compared, and their effect on serum lipid levels is described. Oat beta-glucans are found in various breakfast cereals and snacks. Usually, several servings of these products are required to meet the Food and Drug Administration's claim of reducing the risk of heart disease. The yeast-derived fiber is a more concentrated source of beta-glucan than the oat product. It is currently being tested in a wide variety of food products.     

ERC – An object-oriented refinement calculus for Eiffel

We present a refinement calculus for transforming object-oriented (OO) specifications (or contracts) of classes into executable Eiffel programs. The calculus includes the usual collection of algorithmic refinement rules for assignments, if-statements, and loops. However, the calculus also deals with some of the specific challenges of OO, namely rules for introducing feature calls and reference types (involving aliasing). The refinement process is compositional in the sense that a class specification is refined to code based only on the specifications (not the implementations) of the classes that the specification depends upon. We discuss how automated support for such a process can be developed based on existing tools. This work is done in the context of a larger project involving methods for the seamless design of OO software in the graphical design notation BON (akin to UML). The goal is to maintain model and source code integrity, i.e., the software developer can work on either the model or the code, where (ideally) changes in one view are reflected instantaneously and automatically in all views.Correspondence and offprint request to: Richard F.

A framework for real-time discrete event control

The TTM/RTTL (timed transition model with real-time temporal logic) framework is presented for modeling, specifying, and analyzing real-time discrete-event systems. TTMs are used to represent the process of the plant and its controller. RTTL is the assertion language for specifying plant behavior and verifying that a controller satisfies the specification. The framework adapts features from the program verification literature which are useful for posing problems of interest to the control engineer, such as modular synthesis and design. Examples are used to illustrate the ideas presented. The authors' published analytical results are summarized and referenced     

Partner unsupportive responses, avoidant coping, and distress among women with early stage breast cancer: Patient and partner perspectives.

This 18-month longitudinal study examined the associations among partner unsupportive behavior, avoidant coping, and distress experienced by 219 women with early stage breast cancer. The role of patient and partner ratings of unsupportive behavior were evaluated. Results indicated that patient and partner ratings of unsupportive behavior were highly correlated. Growth curve modeling suggested that unsupportive behavior, from both patient and partner perspectives, predicted more avoidant coping and distress. When partner and patient perceptions were placed in the same model, patient perceptions mediated the association between partners' ratings of their unsupportive behavior and patient distress. Avoidance also mediated the association between unsupportive behavior and distress, extending prior cross-sectional findings. Results highlight the long-term detrimental effects of partners' unsupportive behavior on the quality of life of women with early stage breast cancer.

Use of the Mental Health Inventory with adolescents: A secondary analysis of the Rand Health Insurance Study.

Few instruments exist for the assessment of adolescent mental health. In order to examine the appropriateness of the Mental Health Inventory (MHI) for use with adolescents, secondary analyses were conducted of the large subsample (n?=?953) of adolescents who participated in the community-based Rand Health Insurance Study. The reliability and readability of the MHI were confirmed. Subscales reflecting Psychological Well-Being and Psychological Distress were derived. The MHI, with its adolescent norms, is recommended for the assessment of adolescent mental health, particularly in studies in which comparison to a nonpsychiatric, normative adolescent population is indicated.

Deciding properties of timed transition models

Real-time distributed systems are modeled by a times transition model (TTM). For any finite-state TTM, decision procedures are provided for checking a small but important class of properties (specified in real-time temporal logic). The procedures are linear in the size of the system reachability graph. The class of properties includes invariance, precedence, eventuality and real-time response specifications     

Social support from family and friends as a buffer of low spousal support among mothers of critically ill children: A multilevel modeling approach.

Objective: To investigate whether social support from family and friends (family/friend support) attenuated ("buffered") adverse effects of having low spouse support (spousal support) among mothers of children undergoing hematopoietic stem cell transplantation (HSCT). Design: One hundred sixty-three married mothers who were their child's primary caregiver during treatment completed assessments during the child's hospitalization for HSCT and 3-, 6-, and 12-months post-HSCT. Measures: Family/friend support and spousal support were assessed during hospitalization. Maternal physical and mental health-related functioning (the main outcome measures) were assessed at all timepoints. Results: Multilevel modeling was used to analyze trajectories of maternal functioning. Findings indicated that mothers with low spousal support and low family/friend support demonstrated the worst functioning across all timepoints. Mothers with low spousal support and high family/friend support demonstrated significantly better functioning, supporting the hypothesized buffering effect. Their functioning compared to the functioning of mothers with high spousal support. Moreover, mothers with high family/friend support demonstrated trajectories of physical health-related functioning that were more stable than the trajectories of mothers with low family/friend support. Conclusion: These findings have clinical implications in addition to advancing knowledge of social support processes among couples coping with the shared stressor of a child's life-threatening illness and treatment.

Social-cognitive processes as moderators of a couple-focused group intervention for women with early stage breast cancer.

Objective: The purpose was to examine whether social-cognitive variables would moderate the efficacy of a couple-focused group intervention (CG) for women diagnosed with early stage breast cancer. Design: Participants (N = 238) were randomly assigned to 6 sessions of a couple-focused group versus usual care. Intent to treat growth curve modeling analyses indicated that emotional expression and emotional processing moderated CG effects on depression. Main Outcome Measures: The primary outcome measures for this study were psychological distress and psychological well-being. Results: Treatment attrition analyses separating out participants assigned to but not attending CG indicated that emotional expression, emotional processing, and protective buffering moderated the effects of CG among those who attended CG with the most consistent effects noted for emotional processing on indicators of distress and well-being. Conclusion: The CG intervention may be more effective for patients who begin the group experience using emotional approach coping strategies to deal with cancer.
