Violence and aggression continue to be both public health and economic concerns. The field of violence prediction has undergone a series of changes in an attempt to best assess risk including using unstructured clinical judgment, actuarial measures, and structured professional judgment. Although prediction has become more accurate with improved measures, a new generation has recently emerged with an emphasis on understanding violence, as opposed to merely predicting it, to shift the focus towards violence prevention. In addition to the creation of measures, researchers have sought to identify specific risk factors for aggression and violence including static and dynamic risk factors. Despite research demonstrating associations between neuropsychological and social-cognitive factors, violence risk measures continue to omit these variables. The current study developed a multi-faceted, theoretical model of aggression including social-cognitive, neuropsychological, personality, and psychiatric factors. A community, male sample (N = 1,192) collected through Amazon's MTurk responded to a series of self-report measures and neuropsychological tasks. Utilizing structural equation modeling (SEM), I created a model predicting aggression. Several important paths were significant including from entity theory to aggression, mediated by hostile attribution bias, schizotypy to aggression, mediated by both hostile attribution bias and disinhibition, substance use to aggression mediated by disinhibition, and psychopathy to aggression directly. This model provides a framework for future research that focuses on process factors of violence and aggression.

In today’s technological environment, organizational capabilities for managing change are regarded as important for business survival and growth. In particular, dynamic organizational capabilities have attracted considerable research interest over the past decade. Recently several studies have suggested that dynamic capabilities may be associated with a concept termed organizational fitness. What is not clear in this emerging research stream is whether firms with superior organizational fitness are more likely to prosper than unfit firms. In addition, relatively little attention has been directed toward creating a systemic model of dynamic capabilities that explains organizational fitness. The nature of fitness has been intensively debated in the biological sciences over a period of several decades. A confusing variety of fitness definitions have emerged from this literature. The lack of an agreed definition of fitness has resulted in several streams of research on organizational fitness. As a result of this fragmentation, there has been little progress toward answering the question of how to measure organizational fitness. The fragmentation in organizational fitness literature is problematic, because research into the relationship between organizational fitness and firm performance is not well-advanced. In this study, organizational fitness is defined in terms of organizational capability to produce variation. By defining fitness in this way, the tautological criticisms leveled against existing concepts of fitness are avoided. The definition of fitness proposed here accommodates both an evolutionary learning perspective and a perspective of strategic management, and thus reflects an integrative approach to the concept. A notable feature of the literature exploring organizational fitness is that it has been focused on large corporations. However, a growing body of literature suggests that SMEs are different from large firms and need to be examined in their own right. SMEs are important contributors to business in most countries throughout the world. This study addresses that perceived gap in the literature and asks: What relationship, if any, is there between organizational fitness and business performance for SMEs? Theory is developed and tested here by means of a large sample of SMEs in New Zealand. Two distinct aspects of organizational fitness are identified for SMEs. First, survival fitness is associated with generic combinative capabilities. Second, growth fitness is associated with knowledge assimilation and transformation. SME growth fitness and survival fitness are each found to be positively related to business performance under a variety of contexts. Further, an increase of growth fitness and survival fitness provides a means of alleviating selection pressures for SMEs. That is, dynamic capabilities of knowledge assimilation and integration are found to be positively associated with SME business performance. In contrast to studies that advocate SME development of context-dependent capabilities, the findings of this study suggest an alternative perspective: variable selection pressures can be influenced by SMEs with a high level of survival and growth fitness.

Bronfenbrenners Process-Person-Context-Time model was used to examine the relationships among the process of negative parenting, the person characteristics of child temperament and early aggressive behaviour and the contexts of family income (in)adequacy and maternal depression from infancy to school entry and their effects on the outcome of aggressive behaviour in boys at school entry. The sample included 361 boys in two-parent families who participated in the Canadian National Longitudinal Survey of Children and Youth (NLSCY). Structural equation modeling was used with a repeated measures longitudinal design. The model explained 43% of the variance in boys aggressive behaviour at school age. The results indicated that, by preschool age, boys and mothers behaviours are well established, and that process, person, and context variables all influence the persistence of boys aggressive behaviour. The strength of the effects of these variables increased with their proximity to the developing child and decreased over time. By school age, concurrent effects were not significant. The addition of the contextual variables resulted in ill-fitting models. Modification indices suggested the ill fit was localized in modeling the persistence of maternal depression, and not in the relationship between maternal depression and the other variables in the model. Modification indices also suggested there may be reciprocal effects between boys aggressive behaviour and both negative parenting and maternal depression, but this was not tested. Future research using a cross-lagged panel design could clarify these relationships. This study contributes to a growing body of research on the development of aggressive behaviour in children and underscores the importance of examining the contribution of the multiple levels of process, person, context, and time to the development of aggressive behaviour. Findings of this study provide evidence that the effects of proximal processes and proximal contexts on the development of boys aggressive behaviour are strongest in infancy and toddlerhood, and their consequences extend through to school entry. Initiating prevention and intervention efforts in early childhood that provide parents-to-be and parents of young children with practical direction in ways to engage in positive and responsive interactions with their children would do more to reduce the development of aggressive behaviour in children than would later interventions aimed at changing entrenched behaviours in both parents and children.

Adjustment, particularly in adulthood, is a vague concept discussed among researchers. Most often researchers only consider lack of involvement in problem behavior as criteria for positive adjustment. Furthermore, it is unclear what factors influence the likelihood of adjustment and the influence of race on these factors is unknown. The current study proposed a composite of male adult adjustment that considers what the Wellness Model terms the “wholeness” of an individual. In addition, adolescent predictors of adult adjustment and the influence of race on factors influencing adjustment were examined in a longitudinal sample of 481 males. Results revealed 4 profiles of adjustment: 1 profile that included individuals who were overall adjusted, 2 profiles that included individuals who were moderately adjusted, and 1 profile of individuals who were maladjusted. The majority of the sample was identified as adjusted in that they were financially responsible, did not have psychological problems, engaged in little to no acts of delinquency, and acknowledged at least adequate social support. Note, however, that these individuals did engage in some substance use. The smallest profile of individuals was those who were maladjusted in that they engaged in excessive delinquency, used both drugs and drank alcohol heavily, and lacked a positive support system. However these individuals were also absent of psychological problems and were financially responsible. Findings also uncovered predictors of adjustment, such that high levels of depression, physical punishment, and poor relationships with peers were associated with only moderate levels of adjustment regardless of race. Furthermore, racial differences in predictors of adjustment were found. Anxiety and parent/child communication were associated with only moderate adjustment for African American but not Caucasian males. In contrast, mother’s arrest and peer delinquency were associated with only moderate adjustment for Caucasian American but not African American males. Recommendations for prevention and intervention strategies are discussed.

Urban forest management is being increasingly recognized as a viable policy vehicle for improving the overall quality of life in urban regions, promoting economic well-being as well as mitigating some of the environmental impacts of urbanization. As a complex system of ecological merit, the urban forest is ultimately dependent upon community-directed efforts to protect and maintain its health, largely through tree ordinances. An understanding of how values and other social factors trigger public concern for and management of the local urban forest is important because of ramifications of community urban forestry policy on regional ecosystem functional capacity. This dissertation investigates the influence of individual experience with trees, knowledge about trees, and tree-related attitudes and beliefs on public support for management strategies to protect the urban forest. Attitude theory forms the foundation of the empirical approach used in this study. Drawing from place theory, attitudes representing Sense of Place were hypothesized to also play a role in explaining variation in homeowners’ support of urban forest protection strategies. Data were obtained from a public opinion survey of 800 homeowners living in a major urban area in Southern Appalachia and joined with measurements of tree canopy density. Geographic information systems software was used to create measures of tree canopy density from Light Detection and Ranging data for varying aerial extents around the survey respondents’ properties. Theoretical constructs were formulated and deployed in structural equation models to test the validity of the hypothesized relationships among the constructs, representing predictors of public support for urban forest protection policy. The modeling results showed that place-based contexts are significant in the prediction of community willingness to support higher levels of urban forest protection. Findings from this study suggest that although the presence of urban trees in one’s neighborhood leads a homeowner to place greater importance on various attributes of trees, this does not automatically lead to support for strong tree ordinances. One also must have a basis of attachment to tree places, which is predicted by tree knowledge and experience with caring for trees around one’s home. In conclusion, limitations and suggestions for future research are provided.

The current study examined the factors that affect female political participation in students at women’s colleges and coeducational institutions. The first part of the study consisted of building a model to explain female political participation based on previous research findings. The second part of the study consisted of examining differences between the model and the levels of participation among the two groups. Results showed that only self-esteem, femininity, feminist identification and knowledge of female political leaders significantly impacted political participation. No structural differences in the model were found between the groups. Students at women’s colleges had significantly higher means in political activity than their counterparts at coeducational institutions but there were no significant mean differences in political participation.

This study examined sense of community (SOC) and participant engagement in the first 12 months of a longitudinal, group-based intervention program for parents, Legacy for ChildrenTM. Previous research in self-help/mutual support groups and alternative living environments for recovering addicts suggested SOC may positively influence engagement in programs and may be an active ingredient to the success of such programs. Literature on SOC has been limited by cross-sectional investigations and lacked a developmental perspective of changes in SOC over time. This study examined the following questions: 1) Does SOC with the parenting program differ between intervention and control participants at 6 months and 12 months following entry into Legacy? 2) How do baseline levels of social support, stress, and self-efficacy relate to sense of community with the parenting program? 3) Do intervention participants’ baseline demographic and psychological characteristics relate to attendance and engagement in the first 20 weeks of parent groups? 4) Does participant engagement predict SOC with the parenting program over time? Does early SOC predict later engagement? Study hypotheses were examined using repeated measures ANOVA, hierarchical linear regression, and structural equation modeling. The sample included 289 mothers recruited at the Miami Legacy for Children intervention site; eligible mothers were adults, received Medicaid, were English speaking, and had a newborn child. Mothers were randomly assigned to the intervention or control group. Results of the structural model using only intervention participants suggest that attendance and engagement in parent groups contributed significantly and positively to sense of community with the program over time. The intervention group had a slightly higher SOC with the program than the control group. However, levels of SOC with the program declined from 6 to 12 months among intervention participants while stability or slight increases in SOC characterized the control participants’ SOC during this time. Regardless of experimental condition, changes in SOC within the first year of the program were small in magnitude and suggest that changes in SOC between groups may take more time to evaluate fully. Implications of these findings to the development of SOC in intervention settings are discussed.

Political behavior prevails in organizations. Recently, organization researchers dedicate themselves to the issues related to perceptions of organization politics. The motivation of those organization studies is nothing more than the willingness of improving organization commitment, in turns to enhance long-term competitiveness in organizations. This study is based on the Revised Model of Perceptions of Organizational Politics, Ferris et al (2002), to discuss the relationship among perceptions of organizational politics, organizational commitment, job satisfaction and organizational cynicism. The study also examines whether the perceptions of organizational politics through mediating effects, job satisfaction and organizational cynicism, will influence organizational commitment. After using structural equation modeling¡]SEM¡^ to analyze the research data in 2008, provided by Political Perception Research Team, which is led by Prof. Chin-Ming Ho, the new findings include: 1.For the influence of perceptions of organizational politics to organization commitment: ¡§general political behavior¡¨ shows a significant positive correlation; for ¡§go along to get ahead¡¨, it is not notable; regarding ¡§pay and promotion policies¡¨, it represents significant negative correlation.. 2.There is significant negative impact between perceptions of organizational politics and job satisfaction. 3.There is significant positive impact between perceptions of organizational politics and organizational cynicism. 4.Job satisfaction has positive impact to organizational commitment. 5.Organization cynicism has negative impact to organizational commitment. 6.Job satisfaction and organizational cynicism are the mediators of organizational commitment and perceptions of organization politics.

The community development in Taiwan has its unique connotation and meaning, some scholars pointed that the key to the continuous promotion of community development is in the self identity, collective participation and active support. Promotion of community development fears discontinuity. The phenomenon that commonly appears is discontinuity of residents¡¦ participation or unsatisfactory cohesive force of community. As a consequence, the community development is regarded as a mean to enable collective action of community residents, what affects the communities to enable an effective collective action is an issue to be discussed in the study. There are four purposes of this study : firstly; is to get to know the theoretical base of local community development task in Taiwan; secondly; to proof the effect among social capital, community empowerment and collective action; thirdly; to explore the operation strategies for ¡§urban¡¨ and ¡§rural¡¨ community development and lastly, to combine social capital, community empowerment and collective action theories related aspects to construct a ¡§continuous development model¡¨ for the community development in Taiwan. The research variables with regard to the community collective action of this study include: ¡§civic engagement¡¨, ¡§interpersonal trust¡¨, ¡§social networks¡¨, ¡§community empowerment¡¨, ¡§individual and social benefits (incentives)¡¨ etc., with community participants (effective sample size of 573 people in total) from 19 community development associations as research objects; including 10 communities in Kaohsiung city (urban community), 9 communities in Kaohsiung county and Tainan county (rural community), with questionnaires acquired to proceed reliability analysis and exploratory factor analysis, using Structural Equation Modeling (SEM) to construct variables and model test that affect the collective action of community residents for community development. According to analysis of overall sample, there is certain effect of civic engagement on social capital, community empowerment on social capital, social capital on collective action, and individual and social benefits (incentives) on collective action; moreover, a direct impact of community empowerment is shown on the collective action. According to the model fit outcomes, urban community samples are more close to ideal standard, followed by overall sample. The suggestions and strategies proposed upon the research outcomes were mainly divided into 3 directions : first of all, to increase activity management and construct interactive network from social capital perspective; second, to advance identification affection through learning capability from community empowerment perspective; eventually, to provide incentives to enable an interest from collective action perspective. There shall be positive and effective influence on the community collective action once the community development is planned and fulfilled as per 3 dimensions recommended by the study.
