Implicit theories and personality patterns in child-victim sex offenders

Research has suggested that child sex offenders hold thematically distinct cognitive distortions, which Ward and Keenan (1999) call Implicit Theories. The aim of this preliminary study was to investigate the relationship between offenders’ Implicit Theories and their personality related cognitions. The variables were measured using the Implicit Theory Questionnaire and Millon’s (1990) MCMI-III personality scales. Subjects were 28 male sex offenders against children serving a custodial sentence in New Zealand, who elected to participate in a treatment program. A majority of participants had personality scale scores that reached the clinical threshold. Results found that dependant, depressive and schizoidal personality patterns significantly correlated with Implicit Theories. Clinical and theoretical implications are discussed.

Analyzing international travelers' profile with self-organizing maps

It is generally agreed that knowledge is the most valuable asset to an organization. Knowledge enables a business to effectively compete with its competitors. In the tourism context, an in-depth knowledge of the profile of international travelers to a destination has become a crucial factor for decision makers to formulate their business strategies and better serve their customers. In this research, a self-organizing map (SOM) network was used for segmenting international travelers to Hong Kong, a major travel destination in Asia. An association rules discovery algorithm is then utilized to automatically characterize the profile of each segment. The resulting maps serve as a visual analysis tool for tourism managers to better understand the characteristics, motivations, and behaviors of international travelers.

Family interactions and the development of borderline personality symptoms

This thesis investigated the emergence of borderline personality disorder in adolescence. It found that adolescent sensitivity to, and maternal socialization of, aggressive behaviour is associated with borderline pathology. Change in pathology over time was related to adolescent dysphoric behaviour and sensitivity to inconsistent displays of maternal negative emotion.

Different personality measures for different business outcomes : a comparison of selection criteria used for a management training program

Reports a study in which the MBTI, FIRO-B and PP measures were correlated with employee performance indicators of high potential candidates for management development. The participants were 37 middle level managers in a large trans-national company. Results indicate a disturbing disconnect between measures used in training and development and actual business outcomes that can be presumed to express organisational priorities and goals.

Investigating the female profile of autism

An investigation into the hypothesis that females with high functioning autism present in a way that is not congruent with our current understanding of autism, as our current understanding is largely based on a male profile of autism. Autistic females were found to present differently socially, emotionally and behaviourally from autistic males.

Prediction of chlorine and THMs concentration profile in bulk drinking water distribution systems from laboratory data

Nearly all drinking water distribution systems experience a "natural" reduction of disinfection residuals. The most frequently used disinfectant is chlorine, which can decay due to reactions with organic and inorganic compounds in the water and by liquid/solids reaction with the biofilm, pipe walls and sediments. Usually levels of 0.2-0.5 mg/L of free chlorine are required at the point of consumption to maintain bacteriological safety. Higher concentrations are not desirable as they present the problems of taste and odour and increase formation of disinfection by-products. It is usually a considerable concern for the operators of drinking water distribution systems to manage chlorine residuals at the "optimum level", considering all these issues. This paper describes how the chlorine profile in a drinking water distribution system can be modelled and optimised on the basis of readily and inexpensively available laboratory data. Methods are presented for deriving the laboratory data, fitting a chlorine decay model of bulk water to the data and applying the model, in conjunction with a simplified hydraulic model, to obtain the chlorine profile in a distribution system at steady flow conditions. Two case studies are used to demonstrate the utility of the technique. Melbourne's Greenvale-Sydenham distribution system is unfiltered and uses chlorination as its only treatment. The chlorine model developed from laboratory data was applied to the whole system and the chlorine profile was shown to be accurately simulated. Biofilm was not found to critically affect chlorine decay. In the other case study, Sydney Water's Nepean system was modelled from limited hydraulic data. Chlorine decay and trihalomethane (THM) formation in raw and treated water were measured in a laboratory, and a chlorine decay and THM model was derived on the basis of these data. Simulated chlorine and THM profiles agree well with the measured values available. Various applications of this modelling approach are also briefly discussed.

Clarifying the Effort-Reward Imbalance Model : the role of personality

The thesis aimed to identify the sources of stress experienced by a sample of Australian police officers. It was guided by the Effort-Reward Imbalance Model, augmented with Type A personality components. The findings support the research model and suggest that interventions to reduce stress should focus on reward and recognition.
