Biopsychosocial correlates of weight status perception in Australian adolescents

This study examined the utility of the biopsychosocial model to predict accuracy of weight status perception among Australian adolescents. The factors included in this framework were: age, gender, and BMI-z (biological factors); satisfaction with body weight and shape (psychological factors); socioeconomic status, peer weight (social factors). Cross-sectional data, including measured height and weight, and self-reported weight status, was obtained from 2954 adolescents (mean age = 14.6, 56% male) who participated in the It's Your Move! study. Accuracy of weight status perception was associated with gender, BMI-z, SES, and weight and shape satisfaction. Gender differences in weight status perception were moderated by satisfaction with weight. In boys, weight satisfaction was associated with perceived healthy weight; in girls, it was associated with perceived healthy weight and underweight. Moderately overweight adolescents are most at risk of underestimating their weight status and could benefit from education about the boundaries of the healthy weight range.     

Can there be reasoning with degrees of belief?

In this paper I am concerned with the question of whether degrees of belief can figure in reasoning processes that are executed by humans. It is generally accepted that outright beliefs and intentions can be part of reasoning processes, but the role of degrees of belief remains unclear. The literature on subjective Bayesianism, which seems to be the natural place to look for discussions of the role of degrees of belief in reasoning, does not address the question of whether degrees of belief play a role in real agents’ reasoning processes. On the other hand, the philosophical literature on reasoning, which relies much less heavily on idealizing assumptions about reasoners than Bayesianism, is almost exclusively concerned with outright belief. One possible explanation for why no philosopher has yet developed an account of reasoning with degrees of belief is that reasoning with degrees of belief is not possible for humans. In this paper, I will consider three arguments for this claim. I will show why these arguments are flawed, and conclude that, at least as far as these arguments are concerned, it seems like there is no good reason why the topic of reasoning with degrees of belief has received so little attention.     

The German Adaptation and Standardization of the Personality Assessment Inventory (PAI)

An attempt was made to evaluate the relationship between left-handedness and oppositional tendencies through the use of the White Space (S) response on the Rorschach. Right and left-handed males were administered the Rorschach, and it was found that the left-handed subjects gave significantly more S responses than did the right-handed males. It was felt that the results of this study indicated the existence of a relationship between hand-preference and oppositional tendency. Caution was raised concerning the assumption that oppositional tendencies foster left-handedness. It was pointed out that opposition could also be produced by being left-handed.     

Discriminating Clinical From Nonclinical Manifestations of Test Anxiety: A Validation Study

Test anxiety, although being a very common, severe, and impairing psychological disorder, is not coded as a separate diagnosis in the DSM or ICD. In the present study we investigated whether the Test Anxiety Inventory can be used to discriminate clinical and subclinical levels of test anxiety by comparing patients who seek treatment for their test anxiety in an outpatient clinic with carefully matched students with normal test anxiety. The data from 47 test-anxious patients as well as 41 healthy university students were examined. Results show that a cutoff score of ≥ 80 in the Test Anxiety Inventory can discriminate the clinical group from the control students. The symptom pattern of test anxiety was very consistent in the clinical group regardless of the principal diagnosis allocated by the treating clinician. Comorbid depression did not affect the severity of test anxiety. The motivation to avoid failure was one of the most important differences between patients who sought help for their test anxiety and students with nonclinical levels of test anxiety.     

How Inspecting a Picture Affects Processing of Text in Multimedia Learning

We investigated how a picture fosters learning from text, both with self‐paced presentation and with short presentation before text. In an experiment, participants (N = 114) learned about the structure and functioning of a pulley system in one of six conditions: text only, picture presentation for 150 milliseconds, 600 milliseconds, or 2 seconds, or self‐paced before text, or self‐paced concurrent presentation of text and picture. Presenting the picture for self‐paced study time, both before and concurrently with text, fostered recall and comprehension and sped up text processing compared with presenting text only. Moreover, even inspecting the picture for only 600 milliseconds or 2 seconds improved comprehension and yielded faster reading of subsequent text about the spatial structure of the system compared with text only. These findings suggest that pictures, even if attended for a short time only, may yield a spatial mental scaffold that allows for the integration with verbal information, thereby fostering comprehension.

Shared Leadership and Innovation: The Role of Vertical Leadership and Employee Integrity

Purpose

The purpose of this study was to investigate the relationship between shared leadership, as a collective within-team leadership, and innovative behavior, as well as antecedents of shared leadership in terms of team composition and vertical transformational and empowering leadership.

Design/Methodology/Approach

Data were obtained from a field sample of 43 work teams, comprising 184 team members and their team leaders from two different companies. Team leaders rated the teams’ innovative behavior and their own leadership; team members provided information on their personality and their teams’ shared leadership.

Findings

Shared and vertical leadership, but not team composition, was positively associated with the teams’ level of innovative behavior. Vertical transformational and empowering leadership and team composition in terms of integrity were positively related to shared leadership.

Implications

Understanding how organizations can enhance their own innovation is crucial for the organizations’ competitiveness and survival. Furthermore, the increasing prevalence of teams, as work arrangements in organizations, raises the question of how to successfully manage teams. This study suggests that organizations should facilitate shared leadership which has a positive association with innovation.

Originality/Value

This is one of the first studies to provide evidence of the relationship between shared leadership and innovative behavior, an important organizational outcome. In addition, the study explores two important predictors of shared leadership, transformational and empowering leadership, and the team composition in respect to integrity. While researchers and practitioners agree that shared leadership is important, knowledge on its antecedents is still in its infancy.     

Sales Force Motivation Using Travel Incentives: Some Empirical Evidence

This study examines the use of travel incentives as motivators for a commission only life insurance sales force in the United Kingdom. A sample of 1,083 sales representatives reported that travel is a strong motivator and valued more highly than several other types of incentives.     

Planning bridges the intention–behaviour gap: Age makes a difference and strategy use explains why

Objective: This study examines age-differential association patterns between intentions, planning and physical activity in young and middle-aged individuals. The effectiveness of planning to bridge the intention–behaviour gap is assumed to increase with advancing age. We explore the use of behaviour change strategies that include selection, optimisation and compensation (SOC) as underlying mechanisms for age differences. Methods: In N = 265 employees of a national railway company (aged 19–64 years), intentions, planning, SOC strategy use and physical activity were assessed at baseline (Time 1) and again 1 month later (Time 2). Hypotheses were tested in two different path models. Results: Age moderates the extent to which planning mediates the intention–behaviour relation due to an increasing strength of the planning–behaviour link. As a possible psychological mechanism for these age differences, we identified SOC strategy use as a mediator of the age by planning interaction effect on physical activity. Conclusion: These findings suggest differential mechanisms in behaviour regulation in young and middle-aged individuals.
