Supporting the voice and choice of students : Promoting self-determination in the classroom: an observational study of teacher motivational behaviorNurmi, Bo January 2010 (has links)
<p>Motivation is an important factor when trying to understand human behavior and well-being (Ryan & Deci, 2002), especially for teachers since the occupation involves making students perform certain behaviors (Reeve, 2002). Building on the Self-Determination Theory perspective of motivation the aim of this observational study was to describe and analyze the relation between teacher motivational behavior and student behaviors. The study was conducted over a three week period of observing one class in junior high school and their teachers. The results suggest that when teachers make students aware of themselves, their inner resources and support their choice, self-determined forms of motivation is increased. These findings are discussed as well as structured in a theoretical didactical model which describes how different conditions create different psychological responses.</p>

Mergers and Acquisitions: : Their impact on technological performanceMaloney, Brendan January 2006 (has links)
<p>This Thesis examines the impact of mergers and acquisitions (M&As) on the subsequent technological performance of the related firms. The investigated firms are selected according to their strategic choice which consists in seeing M&As as a shortcut for acquiring technological assets and capabilities and therefore the subsequent technological performance. The relatedness issue as well as the resource-based view of the firm are theoretical hints, which effectiveness on technological performance is discussed. A more managerial approach using case studies is also used in order to demonstrate a new organisational form of cooperation, derived from strategic alliances and M&As. With the help of the Renault-Nissan Alliance it is argued that this hybrid form presents many capacities for developing a successful integration process, and subsequently enhancing technological performance.</p>

Relatedness as an Indicator of Group Cohesion and Its Relationship to Outcomes of a Group-Based CBSM Intervention for Women Who have Completed Treatment for Breast CancerMorillo-Falero, Maria del Rosario 17 August 2009 (has links)
Group delivered empirically supported therapies have been reported to have beneficial effects for cancer patients. However, little is known about the relationship between group cohesion and outcomes of these interventions. This study tested the hypothesis that group cohesion relates to the effects of a group intervention. Participants included 56 women with Stage I to II breast cancer who had completed a 10-week CBSM intervention 3 to 12 months after undergoing surgery and adjuvant therapy. Groups of 3 - 5 participants met weekly for sessions of approximately 1 hour and 45 minutes duration. All participants were assessed at baseline (2 weeks prior to beginning the intervention) and at follow-up (12 weeks after enrollment in the study). Cohesion was measured at the end of each intervention session by External Comfort (EC), a factor of the relatedness scale of the Stuttgarter Bogen instrument (1976). EC denotes an aspect of the sense of comfort of an individual within the group that is dependent on how the group participant relates to other members. EC score for session 9 (EC9), and change in EC from session 2 to session 9 (calculated as a change score, i.e., session 9 score minus session 2 score), were used for analyses as independent variables in simple linear regression models. Dependent variables were also calculated as a change score (i.e., follow-up minus baseline) and included benefit finding (Post Traumatic Growth Inventory PTGI, total score and its 5 factors), depression (CESD), urinary cortisol, and natural killer cell function (total percent, number and cytotoxicity). Results yielded a positive change in EC from session 2 to session 9 (M = 2.29, S.D. = 2.67). Regression analyses indicated a significant negative relationship between change in EC9 and change in total PTGI scores (beta= -.450, p= .011), and change in Factor 1 Relating to Others (beta=-.414, p=.021). A marginally significant negative relationship was observed between change in EC from session 2 to session 9 and the New Possibilities Factor of the PTGI (beta=-.323, p=.077). A median split, by change in EC, indicated that participants with high EC scores throughout the intervention showed an increase in total PTGI scores, and in two of the five PTGI factors at follow-up. In contrast, participants who initially scored lower values in EC showed no change in these variables. These results suggest that the longer it takes an individual to feel comfortable in the group, the less the individual would be able to find benefit from their cancer experience after the intervention.

The Influence of Parent-Child Relatedness and Social Support on Depressive Symptoms in Asthmatic Children: Tests of ModerationCummings, Lawanda 28 July 2006 (has links)
The Brofenbrenner(1979) ecological theory was applied to examine the relationship between parent and child depressive mood and the moderation of relational quality at two levels; 1) parent-child (within family) and 2) family-social support (outside family) levels. It was hypothesized that both levels would buffer the predictive association of parent to child depressive mood. At the first level, the parent-child depressive mood association was qualified by an interaction with relatedness (categorized as inadequate and adequate) that approached a conventional level of significance, R2 = .023, F(1,101) = 2.77, p = .099. At the second level, the addition of social support as a moderator yielded a R2 =.028, F(1,101) = 3.11, p = .081. Exploratory analyses were performed to clarify each moderation. The findings suggest that relational quality within and outside the family have the potential to serve as protective factors in regards to depressive symptoms for children with asthma.

Socio-Ecology and Behavior of Crop Raiding Elephants in the Amboseli ecosystemChiyo, Patrick Ilukol January 2010 (has links)
<p>Abstract</p>
<p>Risky foraging is a male reproductive tactic in most polygynous mammals. It is speculated to result from intense intra-sexual reproductive competition. Consequently this behavior has been speculated to increase a male's reproductive competitiveness. However, individual males may differ in their propensity to take foraging risks. </p>
<p>We therefore conducted a study on crop raiding behavior (a risky foraging strategy) in African elephants from the greater Amboseli ecosystem, in southern Kenya. We specifically examined the population sizes, gender and patterns of raiding elephants and investigated the effect of crop-raiding and genetic heterozygosity on male body size. We also examined the influence of age and genetic relatedness on observed patterns of association. Finally, we examined the role of life history milestones, association patterns and social structure on the acquisition of crop raiding behavior among wild free ranging male African elephants. With regard to the influence of association patterns on crop raiding behavior, we were specifically interested in understanding the mechanisms by which social learning might occur among male elephants.</p>
<p>Our results showed that 241elephants from different populations in the ecosystem converged to raid farms. Approximately 35% of raiders were from Amboseli National Park, and the rest were other populations in the ecosystem. We observed only post-pubertal males but not females to raid. About one third of post-pubertal males from the Amboseli population were raiders. We found evidence of habitual raiding by some individuals. Crop raiding predicted post-pubertal male size, with raiders being larger than non-raiders. This result suggests that taking risks pays off for males. Our results also showed that other variables known to influence growth like genetic heterozygosity had no effect on size-for-age in male elephants, because low-heterozygosity males were rare. The probability that an individual male is a crop raider was greater for older individuals than young males. The probability that a male is a raider was greater when his two closest associates were raiders versus when they were not raiders and when a male's second closest associate was older, versus when his second closest associate was of similar age or younger. These results suggest that increasing energetic demands associated with life history milestones and social learning play a significant role in the initiation of crop raiding behavior. Raiders did not cluster into separate social units from non-raiders, probably due to the nature of social learning exhibited by this species and due to the diffuse nature of male elephant social units.</p>
<p>These results have implications for understanding the evolution of risky foraging behavior in males, and for understanding the role of kin selection, dominance hierarchies and social learning in male elephant social systems. Results also have implications for understanding the spread of adaptive complex behavior in natural populations.</p> / Dissertation

Relationships Between Courage, Self-construals And Other Associated VariablesYalcindag, Bilge 01 September 2009 (has links) (PDF)
As an age old virtue, courage has been linked to several characteristics / however, the number of empirical studies discussing these linkages is few. Also, the literature lacks a proper self report measure of courage. With these voids in mind, the aims of the present research are threefold: a) to develop a new scale to measure courage which has been mostly understood in terms of being able to present oneself in a genuine way, perseverance under difficult circumstances, and pursuit of morally right behavior / b) to investigate self related differences in courage within the context of Balanced Integration and Differentiation (BID) Model of self (imamoglu, 2003) and c) to explore the relationship between courage and other proposed related constructs. A set of questionnaires including the Courage Scale, BID Scale (imamoglu, 1998), Battery of Interpersonal Capabilities (Paulhus, & / Martin 1988), Moral Courage Scale (Bronstein et al, 2007), Short Form of Authenticity Scale (imamoglu et al, 2009), Hope Scale (Snyder et al, 1991), and Voice Scale (Van Dyne, & / LePine, 1998) have been administered to 313 university students (182 female, 127 males and 4 not specified). Results suggested that the newly developed Courage Scale had acceptable levels of internal consistency. Also, it showed converging patterns with Moral Courage Scale which is a more specific measure of the concept throughout different analyses. In congruence with the literature, courage was positively correlated with voice behavior and certain personality characteristics such as self-confidence, assertiveness or honesty. Based on the results, it was concluded that people who have balanced and separated-individuated selves (i.e. who had satisfied both individuational and relational needs and who had satisfied only individuational need, respectively) had higher scores of courage than other self types indicating the importance of intrapersonal developmental orientation for courage. However, both individuation and relatedness were powerful predictors of courage in regression analyses. Results involving a proposed model of courage as a latent variable (predicted by the Courage and Moral Courage Scales) indicated that relatedness, individuation and hope predicted courage indirectly through the mediation of authenticity while the latter two variables also predicted it directly. The study contributed to the literature by exploring the role of self on courage for the first time, by specifying various empirical relationships among concepts that are regarded close to courage and by suggesting a model of courage. The results were discussed in terms of limitations and suggestions as well.
