Self-control,parental crime,and discipline across three generations

The objective of this study is to examine the relationships between self-control, parental crime, and use of discipline across three generations. Data spanning 30 years from the National Longitudinal Survey of Youth, are analyzed using Structural Equation Modeling. This study focuses on whether different types of discipline used by parents predict the self-control of each successive generation. We also examine whether self-control and criminal activities of parents are predictive of parenting and resulting self-control of children. We find that discipline has a weak relationship to self-control but that parental crime and self-control do relate to the self-control of later generations.     

A modal ontology of properties for quantum mechanics

Our purpose in this paper is to delineate an ontology for quantum mechanics that results adequate to the formalism of the theory. We will restrict our aim to the search of an ontology that expresses the conceptual content of the recently proposed modal-Hamiltonian interpretation, according to which the domain referred to by non-relativistic quantum mechanics is an ontology of properties. The usual strategy in the literature has been to focus on only one of the interpretive problems of the theory and to design an interpretation to solve it, leaving aside the remaining difficulties. On the contrary, our aim in the present work is to formulate a “global” solution, according to which different problems can be adequately tackled in terms of a single ontology populated of properties, in which systems are bundles of properties. In particular, we will conceive indistinguishability between bundles as a relation derived from indistinguishability between properties, and we will show that states, when operating on combinations of indistinguishable bundles, act as if they were symmetric with no need of a symmetrization postulate.     

Cognitive Fatigue During Testing: An Examination of Trait,Time-on-Task,and Strategy Influences

Two-wave data from a large sample of employees (N = 1,155) 25–65 years of age were used to evaluate rank-order and mean level stability and change in supervisor-rated job performance obtained twice (4 years apart). Results showed moderated levels of rank-order stability across the career span. However, although rank order stability increased during the first phases of one’s career, peaking at age 55, it then demonstrated a decline from age 55 to age 65. Patterns of mean-level change showed that job performance was generally higher for younger workers than for older workers. All in all, our results support the value of investigating different definitions of job performance change and offers insights for planning/programming and implementing interventions aimed to improve (or maintain) job performance.     

The link between women's body image disturbances and body-focused cancer screening behaviors: A critical review of the literature and a new integrated model for women

A large body of literature demonstrates the association between body image disturbances and health compromising behaviors among women (e.g., pathological eating, substance use, inappropriate exercise). However, given that disturbed body image is a pervasive problem, it is likely inversely related to health maintenance behaviors. Cancer screenings for breast, skin, and cervical cancer represent an important type of health maintenance behavior, yet adherence rates are low. Given the body-focused nature of these screenings, body image may be a salient predictor. This paper reviews the literature on the relationship between body image disturbances and cancer screening behaviors among women culminating in the proposal of a theoretical model. This model posits that body shame and body avoidance predict performance of cancer screenings and that variables drawn from the cancer literature, including risk perception, health anxiety, subjective norms, and self-efficacy, may moderate this relationship. Clinical implications and suggestions for research are discussed.     

Reduced Verbal Memory Retention is Unrelated to Sleep Disturbance During Pregnancy

This study investigated episodic and procedural memory retention in early and late pregnancy and whether memory retention was related to sleep disruption. Twenty‐six women in the third trimester of pregnancy, 20 women in the first trimester of pregnancy, and 24 non‐pregnant controls were administered a battery of verbal and visual episodic memory tasks and two procedural memory tasks before undergoing an overnight sleep study. Memory retention was assessed the following morning. Results indicated that as compared with controls, both pregnant groups had reduced retention in verbal episodic memory but were unimpaired on visual and procedural memory tasks. The pregnant women also demonstrated significant disruption of sleep patterns. Reduced verbal memory retention during pregnancy was not attributable to any measure of sleep; however, small correlations between some indices of sleep and memory do not allow full dismissal of the sleep‐dependent memory consolidation hypothesis.     

Character Disposition and Behavior Type: Influences of Valence on Preschool Children's Social Judgments

The authors studied the influences of valence information on preschool children's (n = 47) moral (good or bad), liking (liked or disliked by a friend), and consequence-of-behavior (reward or punishment) judgments. The authors presented 8 scenarios describing the behavior valence, positive valence (help, share), negative valence (verbal insult, physical aggression), and disposition valence (nice or mean) of characters in social interaction with a friend. Overall, character disposition and behavior valence significantly influenced children's judgments. Moral, liking, and consequence-of-behavior judgments varied significantly by character disposition for both positive behavior scenarios. In contrast, there were fewer significant findings as a function of character disposition for negative behavior scenarios, suggesting that the negative behavior cue somewhat diminished the effect of character disposition on children's judgments. The authors discuss preschool students’ coordination of information about valence of behavior and character disposition and the students’ reluctance to judge that misbehavior warrants punitive consequence.     

Horizontal Plane Head Stabilization During Locomotor Tasks

Frequency characteristics of head stabilization were examined during locomotor tasks in healthy young adults (N = 8) who performed normal walking and 3 walking tasks designed to produce perturbations primarily in the horizontal plane. In the 3 walking tasks, the arms moved in phase with leg movement, with abnormally large amplitude, and at twice the frequency of leg movement. Head-in-space angular velocity was examined at the predominant frequencies of trunk motion. Head movements in space occurred at low frequencies (< 4.0 Hz) in all conditions and at higher frequencies (> 4.0 Hz) when the arms moved at twice the frequency of the legs. Head stabilization strategies were determined from head-on-trunk with respect to trunk frequency profiles derived from angular velocity data. During natural walking at low frequencies (< 3.0 Hz), head-on-trunk movement was less than trunk movement. At frequencies 3.0 Hz or greater, equal and opposite compensatory movement ensured head stability. When arm swing was altered, compensatory movement guaranteed head stability at all frequencies. Head stabilization was successful for frequencies up to 10.0 Hz during locomotor tasks Maintaining head stability at high frequencies during voluntary tasks suggests that participants used feedforward mechanisms to coordinate head and trunk movements. Maintenance of head stability during dynamic tasks allows optimal conditions for vestibulo-ocular reflex function.     

A Commentary on Charles Goodwin's Co-Operative Action for Learning Scientists

ABSTRACT

This commentary summarizes the argument Charles Goodwin presents in Co-Operative Action (Co-A, 2018 Goodwin, C. (2018). Co-operative action. New York, NY: Cambridge University Press. [Google Scholar]), his most recent book. Through exploration of the breadth of conceptual and methodological tools that he has built over the course of his career and represents in this book, we suggest paths forward for Learning Sciences towards engaging in more equitable and relational research.     

Can Perceptions of Supervisor-Related Ethical Climate Influence How High-Impression Managers Admit Past Unethical Behavior?

In this study, we investigated how the perceptions of ethical climate as it relates to supervisor behavior and impression management are related to admission of past unethical behavior in a sample of Canadian Army personnel. We expected that among respondents who perceive less ethical supervisor-related climate, the relationship between Impression Management (IM) and the admission of past unethical behavior should be significant and positive. In contrast, among respondents who perceive a more ethical supervisor-related climate, the relationship between IM and self-report past unethical behavior should be weak or nonsignificant, and the frequency of admission of past unethical behavior should be low. Although moderation occurred, it was not as hypothesized. IM predicted admission of having obeyed, or witnessed others obey an unlawful command when perceptions of supervisor-related ethical climate were low, and not when perceptions of supervisor-related ethical climate were high. However, higher (vs. lower) impression managers admitted less past unethical behavior, regardless of their perceptions of supervisor-related ethical climate. These results suggest that high impression managers do not admit to having obeyed or witnessed others obey an unlawful command in the past, regardless of their perceptions of the ethical climate as it relates to supervisor behavior.
