High-pressure electrical resistivity behaviour of nanocrystalline perovskite (La,Sr)(Mn,Fe)O3

We report here the electrical resistivity of nanocrystalline perovskite-structured La–Sr manganites as a function of pressures up to 8?GPa, at room temperature. The nanocrystalline perovskite manganites were prepared by the sol–gel technique and found to have crystallite sizes of 12–18?nm. The pressure dependence of the electrical resistivity shows a first-order phase transition at 0.66(2)?GPa and a subtle phase transition between 3.5 and 3.8?GPa. The first-order transition at 0.66?GPa can be related to the transition from localized-electron to band magnetism.     

Observation of planar stacking faults in a Ti-rich two-phase Ti-Al alloy after deformation at elevated temperatures

It is a common observation that in two-phase Ti-Al-based binary alloys, deformation of the gamma phase occurs by 1/2<110]-type ordinary dis-location activity and twinning associated with 1/6<112] type partials. In the present study the microstructure of a new Ti-Al-based alloy (Ti-47at.% Al-2at.%Mn-2at.%Nb+ 0.8 vol.% TiB₂) with a duplex microstructure consisting of primary equiaxed gamma grains and lamellar alpha₂+ gamma colonies was studied by transmission electron microscopy (TEM) after deformation at elevated temperatures. Planar stacking faults were found in the gamma laths. A detailed contrast analysis by TEM shows that these planar stacking faults lying on {111} planes are bound by all the fcc variants of the Shockley partial dislocations of type 1/6<121>, in contrast with the observations in stoichiometric binary TiAl alloys, where only 1/6<112]-type Shockley partials are found to be associated with the true twins. It is proposed that the addition of ternary and quaternary elements such as Mn and Nb promotes the other variants of the fcc-like dissociations (not common in L1₀structure) in the present alloy.     

Negative affectivity,perceived occupational stress,and health during organisational restructuring: A follow-up study

Abstract

This paper presents a survey of the relationships among multiple indicators of perceived occupational stress, trait negative affectivity, and later mental and physical health symptoms, among 157 Australian public servants during organisational restructuring. It was hypothesised that individual differences in negative affectivity would inflate the relationships between perceived stress and later strain as assessed by health symptoms in the follow-up phase. The possible role of negative affectivity in moderating the stress-strain relationships was also investigated. Multiple regression analyses conducted with depressive and physical health outcomes separately indicate that the only significant predictors of depressive symptoms were negative affectivity and role insufficiency, whereas the significant predictors of physical health symptoms were role ambiguity, physical environment, and negative affectivity. None of the interaction terms involving occupational stress and negative affectivity was found to be significant Implications of the findings are discussed in the context of the research literature on work stress, particularly the role of negative affectivity in inflating the stress-strain relationship and indications for future research.     

The effect of perceived financial vulnerability on prosocial activity

Our research examines the effect of subjective financial vulnerability on prosocial activity. First, data from the European Survey of Health, Aging and Retirement (SHARE) revealed that higher assessment of one's financial vulnerability might be associated with prosocial motivation for social activities. Next, we manipulated participants' perception of their relative financial position compared to their peers and found that participants randomly assigned to the low financial position condition were more willing to volunteer than participants assigned to the high financial position condition. In Study 3, we manipulated participants' financial advantage. Participants who were disadvantaged in the experimental settings were more willing to volunteer and donate to charity compared to participants with financial advantage. In our final study, we examined willingness to donate to in‐group and out‐group help organizations and found that individuals of lower perceived financial standing may be motivated by the goal of increasing the strength of the social group, rather than by expectations of direct reciprocity. We also found that emotional distress mediates the relationship between perceived financial vulnerability and prosocial behavior. In line with earlier research illustrating that lower financial status promotes prosociality on an interpersonal level, we demonstrate that even momentary perception of relative financial disadvantage and vulnerability promotes prosociality in the broader social context.     

Social support,strain, and glycemic control: A path analysis

Social support and strain have been linked with many health outcomes. However, less is known about whether these psychosocial factors are associated with Type 2 diabetes risk. This study uses the Midlife in the United States (MIDUS) dataset to examine the relationship between social support and strain from friends, family members, and spouse/partners and blood hemoglobin A1c levels in married/cohabiting adults who have not been diagnosed with diabetes. In addition, health locus of control is examined as a possible mediator. The study's findings suggest that support from friends is negatively associated with HbA1c levels, indicating a relationship between better glycemic control and social support from friends, and an indirect association for spouse/partner support. A direct effect for internal health locus of control was also found.     

Resource replacement and psychological well-being during unemployment: The role of family support

There is an established inverse relationship between unemployment and psychological wellbeing. However, little is known about the processes that underlie this relationship. Using latent deprivation, conservation of resources, and social capital to form a theoretical framework, this study explored the relationship between the latent benefits associated with employment, family support, and financial strain. In a sample of 174 unemployed individuals, latent benefits were shown to partially mediate the relationship between family support and psychological well-being. Additionally, this mediation was moderated by financial strain, with latent benefits being more related to psychological well-being in those with greater financial strain. These findings provide guidance in understanding how to better address the needs that contribute to psychological well-being in those who are unemployed.     

Private Investigations of White‐Collar Crime Suspicions: A Qualitative Study of the Blame Game Hypothesis

The activity of private investigations by fraud examiners is a business of lawyers, auditors, and other professionals who investigate suspicions of financial crime by white‐collar criminals. This paper presents results from an empirical study of investigation reports. The available sample consists of 28 reports written mostly by auditing firms such as Deloitte, Ernst & Young, and PwC. The blame game can occur at two stages in a private investigation. First, the mandate formulated by a client may point investigators in a specific direction. Next, investigators sometimes suffer from a tunnel view of predetermined opinions. In the sample of 28 investigations reports, more than half of them involve potential blame game victims.

Are you tired? Spillover and crossover effects of emotional exhaustion on the family domain

This paper examines the spillover and crossover effects of emotional exhaustion on marital satisfaction for both employees and partners as well as on employee work–family conflict and partner family–work conflict. It investigates how the transmission of psychological strain from the workplace to the family domain mediates these relationships. In a sample of 226 employee–partner dyads from manufacturing, electronics, banking, service industries and public organizations, the results support the notion that employees' emotional exhaustion spawns negative strain in the home. More specifically, the results of spillover mediation analyses show the relationships between emotional exhaustion and employee marital satisfaction/work–family conflict in the home. In a crossover model, the results indicate that employee psychological strain mediates the relationships between emotional exhaustion and the marital satisfaction of partners/family–work conflict in partners. These findings provide supports for spillover and crossover models to investigate a direction for the effectiveness of emotional exhaustion on family issues. Theoretical and practical implications of the results are discussed, and directions for future research are offered.     

Do couples who play together stay together? A longitudinal dyadic examination of shared leisure,financial distress,and relationship outcomes

We examined whether shared leisure offers protection against negative associations between financial distress and relationship quality (satisfaction and commitment) for lower- and higher-income couples. We expected husbands' and wives' reports of shared leisure would be protective of the effects of financial distress (Time 2) on relationship satisfaction (Time 3) and commitment (Time 4) for higher-income couples (but not lower-income couples). Participants were drawn from a nationally representative, longitudinal study of US newly married couples. The analytic sample included both members of 1382 different-gender couples with data across the three sampled waves of data collection. Shared leisure was largely protective of the effects of financial distress on husbands' commitment for higher-income couples. For lower-income couples, higher shared leisure exacerbated this effect. These effects were only found at extreme levels of household income and shared leisure. When considering if couples who play together stay together, our findings suggest that it can, but it is critical to understand the financial situation of the couple and the resources they may have to support shared leisure activities. Professionals working with couples should consider their financial situation when making recommendation to engage in shared leisure, such as going out for recreation.
