For many years,scholars haveinvestigated instructional design expertise anddescribed the difficulty definingit. A lack of a clear definition, inclusive of primary components,poses a measurement problemfor those seeking to evaluate the development of expertise. An overarching aim of this study is to gather evidence to support a definition of instructional designexpertise(IDE)which includes knowledge, skills, and dispositions. Instructional design dispositions have not received muchattention, but dispositions (e.g., adaptability,flexibility)are often described as distinguishing traits of expertdesigners. ExistingID competency instrumentsevaluatethe perceived importance of knowledge and skills butare limited in trackingdevelopment past competency. They also do not adequately considerdispositions.The purpose of this research was to describe the development of the Instructional Design Dispositions and Expertise Index. Instrument development procedures includeditem generation,expert review, think-aloud sessions, and a small-scale item tryout. Over 200 designers agreedknowledge, skills, and dispositions are important components of expertise. Qualitative data corroboratedquantitativefindingsfurther illuminatinga relationship between these componentsand quality instructional design. Initial evidence of content and construct validity for the instrument isestablished. A validated expertise instrument wouldallow us to more fully understand and evaluate expertiseand its development, whichcould inspire innovation ininstructional design research, theory, and practice.<br>

The rapid advancement in technology-based systems, especially those related to the Internet and World Wide Web, has led to fundamental changes in how banks interact with customers. These developments have propelled banks to be innovative and use alternative delivery channels such as electronic banking with a view to attract more customers, create value for customers, enhance customer satisfaction and ultimately obtain customer loyalty. Within the South African context, a gap in research was identified that dealt with the conceptualisation and measurement of electronic banking service quality. Furthermore, no single empirical or conceptual study could be found that put up the four constructs identified in this study that tested the causal relationships of these constructs. Against this backdrop, the study‘s principal objective was to develop and validate a measuring scale of electronic banking service quality for the South African banking sector. The study also sought to determine the causal relationships amongst the four constructs of the study, namely electronic banking service quality, customer value, customer satisfaction and customer loyalty. To address these research objectives, the study applied a two-phase design in conducting the research in an effort of enhancing and maximising the outcome of this research endeavour. Phase I of this study comprised a literature review and focus group interviews (qualitative research). An extensive literature review was conducted as an inductive method to build the theoretical foundation of the study, generate the initial pool of items, and define and conceptualise the constructs. Using a deductive method, the focus group interviews were used to generate original items for the development of the scale. Phase II of the study comprised scale refinement and validation of the scale through various interactive statistical applications such as exploratory factor analysis (EFA) and structural equation modelling (SEM) (quantitative method). Using an exploratory factor analysis, eight determinant dimensions were extracted that constitute electronic banking service quality (EBSQ). These dimensions in accordance of their importance are reliability, system availability, privacy and security, website aesthetics, ease of use, functionality, efficiency, and contact and responsiveness. The Pearson‘s correlation coefficient between each of the eight dimensions and EBSQ was above 0.6 at p<0.01 level of significance showing practical significance. Similarly, the Pearson‘s correlation coefficient among the four constructs, namely EBSQ, customer value, customer satisfaction and customer loyalty, revealed that there are evidence positive linear correlations among these constructs. T-test statistics and non-parametric correlations were computed to determine the influence of demographic variables such as gender, age, education and income on the perceptions of customers of electronic banking service quality dimensions, electronic banking service quality as a whole, customer value, customer satisfaction and customer loyalty. Employing comprehensive and best practice (inductive and deductive research methods), a measuring scale has been developed and validated for the South African banking sector (primary objective of this study). The purification and validation of the scale involved rigorous statistical methods including exploratory factor analysis followed by confirmatory factor analysis through structural equation modelling (SEM) to ensure the reliability, validity and robustness of the scale. Moreover, the study endeavoured to contribute to the theoretical conceptualisation of electronic banking service quality (EBSQ), which is a relatively new concept in South Africa, and indeed, globally. Eight dimensions of EBSQ have identified and operational definition provided for. The dimensions identified in this research can be used to better understand EBSQ, and to measure and improve service quality levels in the banking sector. Ultimately, a model has been proposed providing South African banks with an instrument to measure, manage, and improve their electronic banking service quality. The model has established the building blocks of electronic banking service quality by identifying the main dimensions or attributes of electronic banking service quality that can be used to improve service quality levels. Furthermore, the study determined the causal relationships among four constructs, namely (I) electronic banking service quality (EBSQ), (II) customer value, (III) customer satisfaction and (IV) customer loyalty through regression path estimates (coefficients), mediation analysis and standardised regression weights. Understanding the intricate relationships among these constructs will definitely enhance the banks‘ approach to customer relationship management (CRM) in this digital era in their quest to provide quality services and devise appropriate customer service solutions. In light of the findings of this research, several managerial implications and recommendations are offered. Amongst others, the research revealed that reliability, privacy and security are the top concerns customers have with regard to electronic banking. Therefore, it is recommended that banks invest in the robustness of the websites for banking transactions by using cutting-edge technology to protect their customers from illicit criminal activity, as security and trust are of crucial importance to customers when engaging in online transactions. The sample size (310) used in this research is consistent with previously developed and validated scales and sufficiently meets the requirements of sample adequacy for the study of this nature. Using the scale developed and validated in this study, future research endeavours are recommended to use a bigger sample size to test the robustness of this scale, and obtain more exact and organisation-specific customer perceptions of electronic banking services. It may be worthwhile for future studies to consider developing a measuring instrument from a different perspective, that is, from other customer groups, namely internal customers (employees) of the banks. / PhD (Marketing Management)--North-West University, Vaal Triangle Campus, 2015.

The aim of the present work is to develop a tool for identification of Motor Third Party Liability insurance contracts which are at risk of cancellation. Methods for explorative data analysis, building a logistic regression model, comparing models and their validation and calibration are presented. Several models are developed on the real dataset using mentioned methods and then the final one is chosen. Behavior of the final model is verified by the validation on the out-of-time sample. Last step is calibration of the model to the expected value of the future portfolio cancellation rate.

The study presented in this thesis investigates Offshore Information Technology Outsourcing (IT offshoring) relationships from clients’ perspective. With more client companies outsourcing their IT operations offshore, issues associated with the establishment and management of IT offshoring relationships have become very important. With the growing volume of offshore outsourcing, the numbers of failures are also increasing. Therefore, both clients (service receivers) and suppliers (service providers) face increasing pressure to meet with the objectives of IT offshoring initiatives. Improving the quality of the relationship between client and supplier has frequently been suggested in the literature as probable solution area, however not much literature and empirical evidence is available in this respect. The aim of the study is to make a theoretical and practical contribution by studying the interplay between the critical factors influencing the relationship intensity level of the exchange partners and suggest measures that can potentially increase the success rate in IT offshoring engagements. The objectives of this study are: 1. To identify the relevant critical factors and explore its causes and effects (antecedents and consequences) on the relationship intensity significance level. 2. To develop an integrated conceptual framework combining the hypothetical relationship among these identified critical factors. 3. To empirically validate the conceptual framework. To accomplish the first objective and building the theoretical platform for the second objective, three research questions are identified and answered through empirical study backed by literature evidence. The second objective is addressed through an integrative conceptual framework by analysing the related studies across other disciplines, gaps in the existing theories and models in the outsourcing literature. Coupled with literature gap analysis, the researcher adopted some of the relevant features from across various disciplines of management and social sciences that are relevant to this study. After that, the third objective, the research hypotheses are validated with empirical examination conducted in Europe. Seven research hypotheses are developed based on literature analysis on the relationship of the key constructs in the conceptual framework. This study is explanatory and deductive in nature. It is underpinned mainly by a quantitative research design with structured questionnaire surveys conducted with stratified sampling of 136 client organisations in Europe. Individual client firm is the unit of analysis for this study. Data analysis was conducted using partial least squares (PLS) structural equation modelling techniques. In this research, empirical support was found for most of the research hypotheses and conclusions of the study is derived. An investigation into trust as a concept is used to denote relationship intensity, as the central construct of the framework. The validated conceptual framework and tested hypothesis results are the main contributions of this study. The results of this study will also be useful in terms of adopting the conceptual framework linked with hypotheses as a point of reference to begin with, in order to accomplish a healthy exchange relationship. However, a further deep dive and fine tuning the sub-units/composition characteristics of each critical factor may be needed for individual outsourcing initiative(s). This study is particularly relevant to the client-supplier firms already engaged in a relationship but can also be useful to those clients who are planning to begin their journey in IT offshoring in the near future, as a preparatory platform.

Male-perpetrated intimate partner violence (IPV) against women remains as a pervasive and detrimental issue both in the United States and globally. Researchers, counselors, and others often develop psychological measures to help understand the causes of IPV in an effort to prevent this issue from occurring. Debate still persists within IPV research as to the definitive factors that contribute to the perpetration of IPV. The socio-feminist perspective remains as the predominant theoretical basis that drives IPV research and understanding. Despite this, no psychological measure grounded in this theory that predicts IPV perpetration proclivities has been developed and validated to date. The purpose of the current project was to develop and validate a psychological measure that predicts a likelihood to physically abuse a female intimate partner among heterosexual men – the Likelihood to Physically Abuse (LPA) scale. The development of which followed the methods of previously developed and validated measures of likelihood to rape and likelihood to sexually harass. Two studies were conducted that utilized two, independent and samples of adult, English-speaking American men. Study I involved a review of the literature to develop the LPA scale and initial internal reliability testing. Two hundred men were recruited using Qualtrics and were administered the LPA scale online. In Study II, three hundred men were recuited using Qualtrics and were administered the LPA scale along with other measures related to male-perpetrated IPV online. The purpose of the second study was to further test the internal reliability of the LPA scale and test the construct and external validity of this measure. The results from both studies demonstrated good internal reliability and initial evidence for good construct validity of the LPA scale. The LPA scale was concluded to show promising reliability and validity. However, the external validity results require further investigation. Implications for future IPV research and applications, and limitations are discussed.

Global concerns about the preparedness of engineering Ph.D. students for professional practice are not new. In the U.S., educational reform has focused on the research experiences of students to foster better preparation. Yet, little is known about which aspects of students’ research experiences are essential to prepare them for practice due to the heterogeneity of the experiences, and what opportunities they have in their research to practice being a professional. The goal of this study was to develop and initially validate an instrument that measures students’ perceptions of their research experiences utilizing an ontological theoretical framework that focuses on what it means to become a professional. This framework simplified the heterogeneity and allowed for the investigation of how the research experiences of engineering Ph.D. students are providing opportunities for students to practice being a professional. Four distinct phases of development were utilized to accumulate validity evidence for the instrument: a development phase that focused on question generation and review: an initial pilot test that centered on an Exploratory Factor Analysis on responses (n = 236) from a large Midwestern University; a second pilot test that centered on a Confirmatory Factor Analysis on responses (n = 215) from multiple universities; and a Group Analysis phase that tested statistical differences between groups. Three key results emanated from this work. First, the accumulated validity evidence justifies the intended use of the instrument as a research and program evaluation survey to assess engineering Ph.D. students’ research experiences for opportunities to practice being a professional. Second, the results suggest that, on average, students had fewer opportunities to work with professionals (i.e., take on others’ forms of practice) in their research experiences than other types of opportunities. Third, the results suggest that research experiences can be categorized into those that provide significantly more and significantly fewer opportunities for students to practice being a professional. Higher education tends to focus on the epistemological aspects of professional practice preparation, but utilizing an ontological approach can identify gaps in preparation. Implications of the opportunities identified in this study are discussed for faculty, students, other researchers, instrument users, engineering administrators, and national program administrators, with a focus on providing more opportunities to students to practice being a professional. The utilization of an ontological approach for engineering Ph.D. students’ research experiences, including tangible examples and a call for a new vision for U.S. engineering Ph.D. research experiences, are discussed.
