Attachment Styles And Male Sex Addiction, James L. Zapf, Jay Greiner [email protected], James Carroll Jan 2008

Attachment Styles And Male Sex Addiction, James L. Zapf, Jay Greiner [email protected], James Carroll

Walden Faculty and Staff Publications

This study addresses the adult romantic attachment styles of sexually addicted men. The Sexual Addiction Screening Test and the Experiences in Close Relationships Revised were used to determine the presence of a sexual addiction and the participants’ style of romantic attachment. ANOVA revealed that sexually addicted men are more likely to relate with insecure attachment styles. Specifically, sexually addicted men were found to have higher anxiety F(1, 38) = 6.122, p < .05 and avoidance F(1, 37) = 4.685, p < .05 in their romantic relationships. Treatment for male sexual addicts should address both addiction and relationship insecurity.

The purpose of this quantitative study was to examine how educators perceive male and female bullies when they are described as exhibiting identical behavior. Goffman's theory of frames formed the theoretical foundation for this study. The independent variable of this study was gender of bully, and the three dependent variables were internalizing behavior, externalizing behavior, …


A Mathematical Approach For Technology Selection In The Presence Of Slightly Non-Homogeneous Technologies, Reza Farzipoor Saen Jan 2008

A Mathematical Approach For Technology Selection In The Presence Of Slightly Non-Homogeneous Technologies, Reza Farzipoor Saen

International Journal of Applied Management and Technology

The assumption of classical technology selection models is based on complete homogeneity of technologies. In spite of this assumption in many applications some technologies do not comprehensively consume common inputs to comprehensively supply common outputs. The objective of this paper is to propose a model for selecting slightly non-homogeneous technologies. A numerical example demonstrates the application of the proposed method.

Prevalence of onychomycosis, as high as 26.9% in the general population, can be reduced by improving current antifungal treatment. This could be accomplished by understanding prognostic factors, especially healthy nail growth, associated with achieving complete cure. This population-based study aimed to evaluate if healthy nail length or percentage of total full nail length as healthy can be early indictors for complete cure. Logistics regression analyses were performed by comparing variables between a population who achieved the complete cure and a population who failed after both populations received the same antifungal treatment in two large randomized double-blinded clinical trials that assessed …


Student -Teacher Relationships And Their Effect On Student Achievement At The Secondary Level, Cheryl Dix Modlin Jan 2008

Student -Teacher Relationships And Their Effect On Student Achievement At The Secondary Level, Cheryl Dix Modlin

Walden Dissertations and Doctoral Studies

Previous research has demonstrated that adolescent learning increases with a proactive type of student-teacher relationship. However, due to the lack of common expectations for a positive student-teacher relationship, a disconnection occurs for some students, who then may become disengaged at school and may not reach their full potential academically, socially, or developmentally. This mixed method sequential, exploratory design focused on a Midwestern secondary school of approximately 250 students. The disconnection between students and teachers was addressed by investigating positive student-teacher relationships; student achievement; and the connection between student-teacher relationships and achievement. Qualitative data were collected using focus groups of students …

Children’S Goal Profiles And Perceptions Of The Motivational Climate: Interactive Association With Self-Determined Motivation And Affective Patterns In Physical Education, Sam Carr, Daniel A. Weigand Jan 2008

Children’S Goal Profiles And Perceptions Of The Motivational Climate: Interactive Association With Self-Determined Motivation And Affective Patterns In Physical Education, Sam Carr, Daniel A. Weigand

Journal of Social, Behavioral, and Health Sciences

Developing an understanding of youngster’s motivation for physical education (PE) is becoming increasingly important. This study examined the interactive effects of children’s multiple goal profiles and perceptions of the motivational climate on indices of self-determined motivation and affect in 429 students (201 boys, 228 girls; M age = 11.2, SD = .39) in northwest England. MANOVA results revealed a significant (p < .05) main effect for goal profiles and perceived motivational climate. Moreover, a significant interaction between goal profiles and perceived climate was found: Children with high mastery/high performance profiles had high levels of intrinsic motivation and identified regulation, regardless of the climate. In contrast, other profile groups (i.e., high mastery/low performance, low mastery/high performance, low mastery/low performance) were more likely to have high levels of intrinsic motivation and identified regulation from exposure to a perceived mastery climate. These results are discussed in terms of the contribution they appear to make to recent analyses of multiple goals.

Ho'oponopono: Assessing The Effects Of A Traditional Hawaiian Forgiveness Technique On Unforgiveness, Matthew B. James

Walden Dissertations and Doctoral Studies

This study expanded on the existing empirical research on forgiveness and specifically ho'oponopono, a traditional Hawaiian forgiveness process. An extensive literature review revealed that while forgiveness has gained in popularity among researchers and clinicians, few therapeutic process-based models have been researched. Furthermore, ho'oponopono has not been studied as a process-based approach to forgiveness. Therefore, the purpose of the present between-groups, within-groups, repeated measures study was to assess the effects of the application of ho'oponopono (focused on a specific transgressor) on levels of unforgiveness, as measured by the Transgression-Related Interpersonal Motivations Inventory (TRIM). The participants (N = 79) were randomly divided …
