Work-based predictors of mortality: A 20-year follow-up of healthy employees.

Objectives: This study investigated the effects of the Job-Demand-Control-Support (JDC-S) model's components, workload, control, peer and supervisor social support, on the risk of all-cause mortality. Also examined was the expectation that the above work-based components interact in predicting all-cause mortality. The study's hypotheses were tested after controlling for physiological variables and health behaviors known to be risk factors for mortality. Main Outcome Measure: The design used was prospective. Baseline data were obtained from healthy employees (N = 820) who underwent periodic health examinations in 1988. Follow-up data on all-cause mortality were obtained from the participants' computerized medical file, kept by their HMO, in 2008. The baseline data covered socioeconomic, behavioral, and biological risk factors in addition to the components of the JDC-S model. During the period of follow-up, 53 deaths were recorded. Data were analyzed using Cox regressions. Results: Only one main effect was found: the risk of mortality was significantly lower for those reporting high levels of peer social support. The study found two significant interactions. Higher levels of control reduced the risk of mortality for the men and increased it for the women. The main effect of peer social support on mortality risk was significantly higher for those whose baseline age ranged from 38 to 43 but not for the older than 43 or the younger than 38 participants. Conclusion: Peer social support is a protective factor, reducing the risk of mortality, while perceived control reduces the risk of mortality among men but increases it among women.

NIR Fluorogenic Dye as a Modular Platform for Prodrug Assembly: Real‐Time in vivo Monitoring of Drug Release

The ability to monitor drug release in vivo provides essential pharmacological information. We developed a new modular approach for the preparation of theranostic prodrugs with a turn‐ON near‐infrared (NIR) fluorescence mode of action. The prodrugs release their chemotherapeutic cargo and an active cyanine fluorophore upon reaction with a specific analyte. The prodrug platform is based on the fluorogenic dye QCy7; upon removal of a triggering substrate, the dye fluoresces, and the free drug is released. The evaluated camptothecin prodrug was activated by endogenous hydrogen peroxide produced in tumor cells in vitro and in vivo. Drug release and in vitro cytotoxicity were correlated with the emitted fluorescence. The prodrug activation was effectively imaged in real time in mice bearing tumors. The modular design of the QCy7 fluorogenic platform should allow the preparation of numerous other prodrugs with various triggering substrates and chemotherapeutic agents. We anticipate that the development of real‐time in vivo monitoring tools such as that described herein will pave the way for personalized therapy.     

Driving styles and their associations with personality and motivation

The associations between driving styles and the Big-Five personality factors and perceived costs and benefits of driving were examined in order to obtain a more comprehensive understanding of driving styles. Questionnaires tapping driving style, personality traits, motivations for driving, and background variables were completed by 320 drivers (150 men and 170 women). The results show that each driving style is associated with a unique set of sociodemographic, personality, and motivational factors. The reckless and angry styles were both endorsed more by men than women, by younger drivers, and by those displaying higher levels of Extroversion and thrill seeking, and lower levels of Agreeableness and Conscientiousness. However, whereas the reckless style was also predicted by the perceived costs of driving-related distress, as well as higher perceived risk to life among those with higher education, the angry style was also predicted by perceptions of both control and annoyance among more educated drivers. The anxious style was endorsed more by women, and by drivers lower on Conscientiousness and higher on Neuroticism. Individuals reporting this style regard driving as a cause of distress and annoyance, and, depending on their level of education, perceive it as entailing more risk to life and as a potential damage to their self-image (higher education), or as providing more opportunities for impression management (lower education). The careful driving style was endorsed more by women, and associated with higher Agreeableness, Conscientiousness, and Openness, along with higher pleasure (especially among younger drivers), but lower thrill seeking and worries about damage to self-esteem. The discussion focuses on the importance of looking at driving styles and their predictors holistically in order to design practical interventions suited to different profiles of drivers.     

Evaluation of a program to enhance young drivers’ safety in Israel

Young drivers in Israel, as in other parts of the world, are involved in car crashes more than any other age group. The graduated driver licensing system in Israel requires that all new drivers be accompanied by an experienced driver whenever they drive for the first 3 months after obtaining a driving license. In an effort to make the accompanied driving phase more effective, a novel program which targets both young drivers and their parents was initiated in 2005. The program administers a personal meeting with the young driver and the accompanying parent scheduled for the beginning of the accompanied driving phase. In this meeting guidance is given regarding best practices for undertaking the accompanied driving, as well as tips for dealing with in-vehicle parent–teen dynamics. Through 2008, almost 130,000 families of young drivers have participated in the program.     

Others' anger makes people work harder not smarter: The effect of observing anger and sarcasm on creative and analytic thinking.

The authors examine whether and how observing anger influences thinking processes and problem-solving ability. In 3 studies, the authors show that participants who listened to an angry customer were more successful in solving analytic problems, but less successful in solving creative problems compared with participants who listened to an emotionally neutral customer. In Studies 2 and 3, the authors further show that observing anger communicated through sarcasm enhances complex thinking and solving of creative problems. Prevention orientation is argued to be the latent variable that mediated the effect of observing anger on complex thinking. The present findings help reconcile inconsistent findings in previous research, promote theory about the effects of observing anger and sarcasm, and contribute to understanding the effects of anger in the workplace.

Does hardiness contribute to mental health during a stressful real-life situation? The roles of appraisal and coping.

Israeli recruits (N?=?276) completed questionnaires on hardiness, mental health, cognitive appraisal, and ways of coping at the beginning and end of a demanding, 4-month combat training period. Path analysis revealed that 2 components of hardiness—commitment and control measured at the beginning of the training—predicted mental health at the end of the training through the mediation of appraisal and coping variables. Commitment improved mental health by reducing the appraisal of threat and the use of emotion-focused strategies and by increasing secondary appraisal. Control improved mental health by reducing the appraisal of threat and by increasing secondary appraisal and the use of problem-solving and support-seeking strategies.

The effects of positive emotion priming on self-reported reckless driving

Five studies examined the effects of positive emotion priming on the willingness to drive recklessly. In all five, young drivers were exposed to one of the following primes of positive affect: a positive mood story; happy memories; an exciting film; a relaxing film; or thoughts on the meaning in life. Following the prime, the participants were asked to report on their willingness to drive recklessly. The responses were compared to those of groups exposed either to neutral affect, another kind of positive affect, or negative affect priming. In two of the studies, participants were also asked to report on their driving styles (risky, anxious, angry, or careful) as a second dependent variable. Positive affect, especially in the form of arousal, was found to be related to higher willingness to drive recklessly. Although men tended to report higher intentions to drive recklessly, men and women did not react differently to the emotional induction. Most interestingly, positive emotions of a relaxing nature, as well as thinking about the meaning in life, lowered the willingness to engage in risky driving. The discussion emphasizes the importance of looking for new ways to use positive emotions effectively in road safety interventions, and considers the practical implications of the studies.
