Conceptualizations of valence and instrumentality: A fourfold model

Within the framework of valence-instrumentality (VI) theory, a fourfold model is developed to predict the contribution which is made by one outcome of an alternative to the valence of that alternative. The proposed model uses four subjective conditional probabilities which are based on the presence and absence of an alternative, and on the occurrence and nonoccurrence of an outcome. Valence is defined as the difference between the attractiveness values of the occurrence of an alternative (or an outcome) and the nonoccurrence of an alternative (or an outcome). Also, differences between subjective probabilities replace instrumentalities. Alternative valence-instrumentality formulations are analyzed in relation to the proposed fourfold model. The proposed model can be understood as a consistent application of Vroom's model (1964, Work and motivation, New York: Wiley), while other models are judged to be relatively deficient. The fourfold model, in combination with a matrix formulation of expectancy concepts, addresses a number of criticisms of VI theory and makes possible a test of the theory within the limits of its own assumptions.     

A review of time-motion analysis and combat development in mixed martial arts matches at regional level tournaments

Mixed martial arts (MMA) have become a fast-growing worldwide expansion of martial arts competition, requiring high level of skill, physical conditioning, and strategy, and involving a synthesis of combat while standing or on the ground. This study quantified the effort-pause ratio (EP), and classified effort segments of stand-up or groundwork development to identify the number of actions performed per round in MMA matches. 52 MMA athletes participated in the study (M age = 24 yr., SD = 5; average experience in MMA = 5 yr., SD = 3). A one-way analysis of variance with repeated measurements was conducted to compare the type of action across the rounds. A chi-squared test was applied across the percentages to compare proportions of different events. Only one significant difference (p < .05) was observed among rounds: time in groundwork of low intensity was longer in the second compared to the third round. When the interval between rounds was not considered, the EP ratio (between high-intensity effort to low-intensity effort plus pauses) was 1:2 to 1:4. This ratio is between ratios typical for judo, wrestling, karate, and taekwondo and reflects the combination of ground and standup techniques. Most of the matches ended in the third round, involving high-intensity actions, predominantly executed during groundwork combat.     

The Impact of Children's Language Ability on Parent Cognitions and Harsh Discipline Practices

This study examined associations between children's language ability and maternal cognitions about the intentionality and aversiveness of child behaviour, and mothers' reported harsh discipline responses to child misbehaviour. We tested associations with each type of cognition separately as well as in a single model to explore their unique associations. Participants included 69 mothers and their 18‐ to 37‐month‐old children. Mothers completed the Parenting Scale and were asked to rate the aversiveness and intentionality cognitions in response to eight common toddler problem behaviours. The Preschool Language Scale was administered to the children by an objective evaluator. A path analysis demonstrated that children's language ability was associated with maternal intentionality cognitions about their children's behaviour, which, in turn, was associated with mothers' harsh discipline. These findings highlight the importance of examining developmental markers of harsh parenting. Copyright © 2013 John Wiley & Sons, Ltd.     

The Ant and the Grasshopper: Adolescents’ Time Perspective,Satisfaction with Life and the Mediating Role of Hope

The present study examined the predictive role played by the three time perspective’s dimensions (Present-Hedonistic, Present-Fatalistic and Future) on the satisfaction with life and the mediational role of hope in adolescence, using cross-sectional data. Participants were 675 adolescents (333 males and 342 females), with a mean age of 17.4 years (SD = .84). Adolescents lived in Rome and its surroundings regions and attended the 3th or the 4th year of high school. A structural equation modeling was used. The results shown that Present-Hedonistic predicts directly and indirectly (through agency) the life satisfaction; Future and Present-Fatalistic predicts indirectly (through agency) the life satisfaction; the Present-Hedonistic and Future predicted the pathway, but it does not seem to play a role of mediator. This model is the same for males and females. These results offers new useful guidance to adolescents’ counsellors and educators that should endeavor to increase the hope of both Present and Future oriented adolescents.     

Role of muscarinic M1 receptors in inhibitory avoidance and contextual fear conditioning

The objective of the present study was to observe the effects of pre-training or post-training administration of dicyclomine, a M1 muscarinic antagonist, on inhibitory avoidance (IA) and contextual fear conditioning (CFC) and to investigate if the effects observed with the pre-training administration of dicyclomine are state-dependent. For each behavioral procedure (IA and CFC) groups of Wistar male rats were treated with saline or dicyclomine either 30 min before training (pre-training), immediately after training or 30 min before training/30 min before test (pre-training/pre-test). The animals were tested 24 h after training. The acquisition of IA and CFC was impaired by pre-training administration of dicyclomine. The consolidation of both tasks was not affected by dicyclomine given immediately after training. Pre-training/pre-test administration of dicyclomine impaired both tasks, an effect similar to that observed in the group which only received pre-training administration. Pre-test treatment induced dissociation between both tasks, impairing CFC retrieval, without interfering with the animals avoidance response. These results show that the dicyclomine did not affect IA and CFC consolidation, suggesting specific involvement of M1 muscarinic receptor only in acquisition these tasks, and these effects was not state-dependent. However, it is possible that the retrieval of these tasks may be mediated, at least in part, by different neurochemical mechanisms and may be dissociated by dicyclomine.     

Negative Emotion in the Workplace: Employee Jealousy and Envy

Nine hypotheses were developed from the emerging literature on negative emotion in the workplace. In order to test these hypotheses, the responses of 167 employed master's students to measures of individual differences (self-esteem and Machiavellianism), work unit attributes (autonomy, competitive reward, and supervisory considerateness) and personal response variables (sense of control, organization-based self-esteem, and propensity to quit) were analyzed with bivariate and hierarchical regression analyses. Results of these analyses were generally supportive of the predicted relationships. Findings are interpreted as indicating the utility of the constructs of employee jealousy and envy for understanding individual experiences of interpersonal stress.     

Psychometric Evaluation of the Parent Anger Scale

This study assessed the factor structure and psychometric properties of the Parent Anger Scale in a sample of 326 parents of children ages 2–18 years. Exploratory factor analysis identified a two-factor solution: parent anger experience and parent anger expression. Subscales based on the items of each factor demonstrated excellent internal consistency and concurrent validity with measures of other negative affect and parent discipline. The Parent Anger Scale subscales also evidenced incremental validity, predicting discipline behaviors uniquely above that predicted by parents’ general anger and general anxiety. Specifically, analyses indicated that the Parent Anger Scale experience and expression scores were each unique predictors of inconsistent and punitive parental discipline after controlling for the influences of general anger and anxiety. However, only the Parent Anger Scale expression score had a significant incremental effect in negatively predicting positive parenting above the effects of parents’ general anger and anxiety. Results suggest that the Parent Anger Scale is a valid and useful measure for assessing anger specific to the parent-child context. However, additional research exploring the factor analytic structure and predictive value of the Parent Anger Scale in a clinical sample is needed.     

The utility of transactional and transformational leadership for predicting performance and satisfaction within a path‐goal theory framework

In a test of hypotheses derived from the integration of principles of path‐goal theory ( House, 1996 ) and transformational leadership theory ( Bass, 1985 ), data collected from 179 high school teachers and their principals were examined with hierarchical regression analysis. Augmentation analysis indicated that transactional leadership had a stronger role in explaining unique criterion variance beyond the contribution of transformational leadership, than did transformational leadership relative to transactional leadership. In addition, both the transactional and transformational leadership had a negative interactive relationship for predicting the outcome of performance, such that leader vision and leader intellectual stimulation were more positively correlated with employee performance when leader use of contingent reward was low. These augmentation effects, in conjunction with the findings of negative moderation, suggest that transactional leadership may have greater potential predictive value than previously assumed.     

Predicting employee turnover from performance,satisfaction, and leader-member exchange

As part of a study of the role of supervision in, predicting turnover, 105 nurses provided confidential data on leader-member exchange and satisfaction with supervision, while their supervisors provided performance evaluation information. Although results reaffirmed an inverse correlation between employee performance and turnover (r=–.23p<.05), only directional support was obtained for the hypothesis that performance moderates the relationship between satisfaction with supervision and turnover. Turnover was also not found to be curvilinearly related to performance. Additionally, the, results did not replicate an earlier finding that leader-member exchange is a strong predictor of empolyee turnover. The results are interpreted as underscoring the difficulty of predicting turnover from affect, and the need to, develop refined theoretical models that specifically link these constructs.     

Psychometric characteristics of the Parenting Scale in a Vietnamese sample

The Parenting Scale (PS) is a well‐established instrument for measuring discipline practices in Western populations. However, whether the PS is a valid and reliable measure in Eastern populations is not known. Thus, this study examined the psychometric properties of the PS in a sample of 433 Vietnamese parents of children aged 2–7 years. Confirmatory factor analyses (CFAs) examined the commonly used Reitman et al.'s two‐factor and Rhoades and O'Leary's three‐factor solutions. Neither factor structure fit the data. An exploratory factor analysis identified a 12‐item one‐factor and 14‐item two‐factor solutions that overlapped substantially with established factor structures. The one‐factor solution reflected Lax/Overreactive parenting and the two‐factor solution consisted of Lax/Overreactive and Hostile subscales. The factor structures were confirmed via multigroup CFA. Internal consistencies were acceptable and ranged between .70 and .85. Each factor was positively associated with parent anger, dysfunctional cognitions about child behaviour, and externalising child behaviour problems. However, when entered simultaneously in a regression, Hostile discipline was not uniquely associated with child behaviour. Overall, results support the potential utility of the 12‐item one‐factor PS as a measure of dysfunctional parenting practices for Vietnamese parents.
