THE EFFECT OF INBREEDING ON SOCIALITY IS STUDIED THEORETICALLY FOR THE EVOLUTION OF INTERACTIONS BETWEEN SIBLINGS IN CERTAIN MIXED MATING SYSTEMS THAT GIVE RISE TO INBREEDING: sib with random mating and selfing with random mating. Two approaches are taken. First, specific models of altruism are studied for the various mating systems. In the case of the additive model, inbreeding facilitates the...

Objective: Psychological wellbeing and ego-resiliency are highly affected in a chronic disease like type 2 diabetes mellitus (T2DM), where psychological interventions are considered as an option. The present study, therefore, aimed to investigate the effectiveness of cognitive-behavioral therapy (CBT) on psychological wellbeing and ego-resiliency of T2DM in Sabzevar, Iran. Materials and Method...

This paper asks whether individuals consider the value future generations will receive from environmental quality when deciding what level of environmental protection to provide. Using data on life expectancy, I develop two tests for altruism towards future generations. One, a test for strong altruism, asks whether individual motives are purely altruistic when deciding to provide environmental ...

It is essential for corporate social responsibility that staff can trust its leaders. This paper argues that trust in leaders depends on the relationship between the leader’s values, words and actions. If they are in line, employees can trust the leader. If they are not, distrust prevails. Five alternative relationships between values, words and actions can be identified: (1) values = words = a...

In Caenorhabditis elegans, as in other animals, Notch-type signaling mediates numerous inductive events during development. The mechanism of Notch-type signaling involves proteolytic cleavage of the receptor and subsequent transport of the receptor intracellular domain to the nucleus, where it acts as a transcriptional regulator. Notch-type signaling activity is modulated by post-translational ...

This study investigated gender, age group and locality differences in adolescent athletes' self-determination motivation and goal orientations in track and field. It also examined the relationship between the self-determination theory and achievement goal theory. A total of 632 (349 boys, 283 girls) adolescent athletes (aged 13-18 years) completed the Sports Motivation Scale and Task and Ego Or...

Exerting self-control in a first task weakens self-control performance in a subsequent unrelated task (ego depletion). In self-control research new strategies are required to investigate the ego-depletion effect, which has recently been shown to be more fragile than previously assumed. Moreover, the relation between ego depletion and trait self-control is still unclear, as various studies have ...

In this study, we examined interfering thoughts during sport competition among university volleyball players as a function of dominant goal orientation and outcome. In particular, we investigated the performance worries and thoughts of escape experienced while performing in athletes with high task and low ego orientation and athletes with high ego and low task orientation. Goal orientations wer...

Ego state therapy (EST) evolved from a psychodynamic understanding of personality as a product of an individual's ego states to a conceptualization of how ego-energized and object-energized elements are bound together to cope with a traumatic event. Neurobiological studies now substantiate Watkins's war neuroses conceptualizations. Because of their severity, trauma memories are encoded in the s...
