Assessing Life Balance and Work Addiction in High‐Pressure,High‐Demand Careers

Life balance is indicative of creating and sustaining a meaningful and satisfying quality of living. Contrarily, work addiction is overinvesting in work‐related behaviors, thereby truncating important life‐balance domains. Given a growing body of literature specific to life balance and the increasing incidence of work addiction and burnout among professionals, the authors evaluated life balance and work addiction among 409 professionals in high‐pressure, high‐demand careers. A strong relationship between life‐balance domains and the propensity toward work addiction was noted. Specifically, stress/anxiety and sleep disturbances were identified as work addiction indicators reducing perceptions of life balance. Counselors should assess these critical domains with clients working in high‐pressure, high‐demand careers and be prepared to support these professionals as they restructure their lives to improve life‐balance domains.     

Leptin inhibits and ghrelin augments hypothalamic noradrenaline release after stress

Metabolic conditions affect hypothalamo-pituitary-adrenal responses to stressful stimuli. Here we examined effects of food deprivation, leptin and ghrelin upon noradrenaline release in the hypothalamic paraventricular nucleus (PVN) and plasma adrenocorticotropic hormone (ACTH) concentrations after stressful stimuli. Food deprivation augmented both noradrenaline release in the PVN and the increase in plasma ACTH concentration following electrical footshocks (FSs). An intracerebroventricular injection of leptin attenuated the increases in hypothalamic noradrenaline release and plasma ACTH concentrations after FSs, while ghrelin augmented these responses. These data suggest that leptin inhibits and ghrelin facilitates neuroendocrine stress responses via noradrenaline release and indicate that a decrease in leptin and an increase in ghrelin release after food deprivation might contribute to augmentation of stress-induced ACTH release in a fasting state.     

Mediating relationship between body mass index and the direct measures of the Theory of Planned Behaviour on physical activity intention

This research examines (a) the interrelationships between body mass index (BMI), the direct measures of the Theory of Planned Behaviour (TPB) and physical activity intention and (b) the potential mediation effects of the direct measures of the TPB in the relationship between BMI and physical activity intention in a sample of Australian adults. A total sample of 1,062 respondents participated in a computer-assisted telephone-interview (CATI) survey comprised of a standardised introduction; questions regarding TPB and physical activity; and standard demographic questions. BMI for each participant was calculated from self-reported height and weight. Separate regression analyses were performed to examine the mediating effects of each of the direct measures of the TPB on the predictive relationship between the BMI and physical activity intention, as proposed by Baron and Kenny (Journal of Personality and Social Psychology, 51(6), 1173 - 1182, 1986). Findings indicated that the direct measure of attitude and perceived behavioural control mediated the relationship between BMI and physical activity intention. However, the direct measure of subjective norm failed to act as a mediating mechanism. To date there has been no research that has examined the mechanism by which body mass may affect physical activity behaviour. Given the current focus for health promotion specialists on promoting physical activity as a strategy for reducing overweight and obesity, a theoretical understanding of weight-related barriers to physical activity may aid in the development of future interventions and community physical activity programs, particularly those targeting overweight and obese populations.     

Monkeys match and tally quantities across senses

We report here that monkeys can actively match the number of sounds they hear to the number of shapes they see and present the first evidence that monkeys sum over sounds and sights. In Experiment 1, two monkeys were trained to choose a simultaneous array of 1-9 squares that numerically matched a sample sequence of shapes or sounds. Monkeys numerically matched across (audio-visual) and within (visual-visual) modalities with equal accuracy and transferred to novel numerical values. In Experiment 2, monkeys presented with sample sequences of randomly ordered shapes or tones were able to choose an array of 2-9 squares that was the numerical sum of the shapes and sounds in the sample sequence. In both experiments, accuracy and reaction time depended on the ratio between the correct numerical match and incorrect choice. These findings suggest monkeys and humans share an abstract numerical code that can be divorced from the modality in which stimuli are first experienced.     

Feedlot veterinarians' moral and instrumental beliefs regarding antimicrobial use in feedlot cattle

This cross‐sectional survey research study examined the role moral beliefs play in predicting behavioural beliefs and attitudes and the role that subjective norms play in predicting moral beliefs. Using a self‐administered questionnaire, one hundred and three feedlot veterinarians completed measures of behavioural beliefs, referent others, perceived constraints and moral beliefs regarding recommendations to use antimicrobials in four situations (i.e. acutely sick cattle, chronically sick cattle, at‐risk cattle and high‐risk cattle). Regression analysis and F‐tests indicate moral beliefs as contributing significant increases in R² to models predicting behavioural beliefs regarding antimicrobial use in each situation. In addition, subjective norms contribute a significant increase in R² in models predicting moral beliefs in each of the four situations. The results indicate the effects of moral beliefs on behavioural beliefs are somewhat contingent on the condition; that is the level of risk associated with treating cattle with antimicrobials, the level of risk of not doing so, and the effectiveness of the antimicrobial in situations such as acute illness or being at‐risk of illness.

Using E-Z reader to model the effects of higher level language processing on eye movements during reading

Although computational models of eye-movement control during reading have been used to explain how saccadic programming, visual constraints, attention allocation, and lexical processing jointly affect eye movements during reading, these models have largely ignored the issue of how higher level, postlexical language processing affects eye movements. The present article shows how one of these models, E-Z Reader (Pollatsek, Reichle, & Rayner, 2006c), can be augmented to redress this limitation. Simulations show that with a few simple assumptions, the model can account for the fact that effects of higher level language processing are not observed on eye movements when such processing is occurring without difficulty, but can capture the patterns of eye movements that are observed when such processing is slowed or disrupted.     

Equity Sensitivity Revisited: Contrasting Unidimensional and Multidimensional Approaches

Purpose  Past research has shown little support for direct relationships between equity sensitivity and various equity-relevant criteria. Recent work by Davison and Bing (J Manag Issues 20: 131–150, 2008) suggests that equity sensitivity consists of separate input- and outcome-focus dimensions and that these dimensions are associated with such criteria in an interactive fashion. The current study extends this research by theoretically strengthening and empirically testing their two-dimensional model. Design/methodology/approach  We surveyed adults who were working at least 30 h a week at three time periods to temporally separate measurement of predictors and criteria (n = 172). Findings  Results provide support for the two-dimensional model. Input and outcome focus interacted to explain variance in individuals’ satisfaction and self-reported job performance even after controlling for demographic characteristics, personality, and social desirability. By contrast, the original ESI only significantly predicted one of 10 dependent variables. Implications  Whereas a ratio has been historically used as the basis for evaluating equity, employing independent dimensions and investigating their interaction seems more appropriate to assess individuals’ equity sensitivity. The current study suggests a multidimensional measure of equity sensitivity may better reflect the original theoretical underpinnings of the construct. Originality/value  The current study enhances our understanding of equity theory in general, and equity sensitivity in particular, by drawing attention to the multidimensional nature of the equity sensitivity construct. In particular, it extends the work of Davison and Bing (J Manag Issues 20: 131–150, 2008) by revisiting Huseman et al.’s (Acad Manag Rev 12: 222–234, 1987) original conceptualization of equity sensitivity. In doing so, we broaden its utility as a potential unique predictor of organizationally relevant criteria.     

Balance Theory Applied to Service Quality: A Focus on the Organization, Provider, and Consumer Triad

As quality experts have focused primarily on manufacturing, theoretical frameworks for examining quality in the service sector are lacking. In order to fill this gap, Heider's (1958) balance theory is applied to explain how service organization, service provider, and consumer interrelationships influence service quality. Propositions are offered pertaining to: (a) how and why positive or negative relationships among the parties in this triad are developed, and (b) the consequences of these relationships on service quality, affective outcomes, and withdrawal behaviors. Examination of the service triangle within this framework can enhance understanding of quality service delivery and guide future research efforts in the continuous improvement domain.
