In the current South African context, job insecurity has become a phenomenon to be reckoned with. Although research on this phenomenon is still scarce, a growing interest in the perceived experience of job insecurity and its different underlying constructs is obvious from the increase of job insecurity research. A comprehensive summary of previous research studies and relevant outcomes is therefore relevant. Up to now, South African studies on job insecurity have accepted the assumptions and context of international research studies on job insecurity. It is now time to investigate the influence of the South Afncan context on this phenomenon and to include this background in future studies. The main objective of this study was to review, investigate, compare, evaluate and interpret existing research, conducted internationally and nationally, in order to set a research agenda through proposing a theoretical model for job insecurity in South Afncan organisations. The model will primarily serve as an academic tool to new research scholars to identify new research problems, existing sources of information, relevant measuring instruments, and contextual variables that may be of interest. The model will also be applicable as a management tool to understand and deal with job insecurity in South Ahcan organisations. A qualitative, descriptive research design was followed to perform content analysis and an extensive literature review. Results of the qualitative content analysis were enhanced with semi-structured interviews with managers from different organisations (N = 24). Results indicated gaps between international and South African research studies as well as the gaps indicated between theory and practice. This was indicated by a comparison between the South African research results and the results from the semi-structured interviews with selected managers. These results were integrated into a proposed model for job insecurity in order to serve as a guideline for future research. It also serves as a tool for managers to be aware of the presence of job insecurity, and to enable them to improve their management intervention. Conclusions and limitations of the study were discussed and recommendations for organisations and for future research were made. / Thesis (M.A. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2007.

In South Africa, the staff of higher education institutions experiences several stressors in their work and home domains. Therefore, it is important to understand how these two life domains are in interaction with each other. The general objective of this study was to investigate how higher education staff experienced work-personal life interaction (WPLI). A sample of 24 higher education staff that was willing to participate in the study was taken from different faculties and departments from a higher education institution in the Free State Province. For the purpose of this research, a qualitative design from a phenomenological approach was used. The specific objectives of this study were to determine the experiences, main dimensions, antecedents, consequences, and strategies in the lives of higher education staff. The results obtained indicated that Afrikaans and African women and men experienced time and strain-based conflict. Their work environment was characterised by a heavy workload, long working hours, resulting in work being taken home, and their home environment was characterised by a demanding family (spouses and children) and household duties. Men and women also thought about things in the family domain (e.g., when their children were sick) while they were at work. This caused a constant spill over, leaving employees tired and stressed. Strategies (e.g., prioritising, planning and time management) and support (e.g., spouses, division of family and household duties, friends and colleagues, as well as the flexible working hours) helped them to cope with this interaction. Recommendations were made for future research and the organisation. / Thesis (M.Com. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2007.

Hardly any research has been done on work-life interaction (WLI) in the mining industry in South Africa. Mining is a high-risk profession and the custom of reducing the occurrence of morbidity and inhumanity in these industries must be gainfully considered. Many of the individuals who work in the mining industry are shift workers. Individuals who are working shifts often appear to have little time for non-work related commitments. Their families, personal health, socialising with friends, maintenance of their households and hobbies do not receive the necessary attention, which cause an imbalance of work and life. The general objective of this research was to study the experience of WLI of two cultural groups (Afrikaans and Setswana-speaking individuals) in the mining industry and more specifically, to determine certain antecedents, consequences and strategies used with regards to WLI. A non-probability purposive voluntary sample of 25 mineworkers was taken from the Northern Cape Province. Participants consisting of males and females were stratified in terms of language (Afrikaans and Setswana). Data collection for this research consisted of a pilot study, qualitative interviews and field notes, The data was transcribed verbatim and checked by independent researchers. Content analysis was used to analyse the data. It was found that Afrikaans males, Setswana males and Setswana females experienced pressure and stress at work, where the Afrikaans females did not have that same experience. Several antecedents (e.g., pressure at work, heavy workload, stress, and family obligations) that led to definite consequences (e.g., lack of quality time for self and family, physical and emotional strains, and low levels of productivity), as well as the strategies (e.g., prioritising, time management, communication and planning) which the different language groups use to cope with their work-life interaction were revealed during interviews. The results also confirmed that there were some major differences between Afrikaans and Setswana-speaking individuals in terms of their experiences of work-life interaction. Recommendations were made for the organisation and for future research. / Thesis (M.Com. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2007

Work and family constitutes the dominant life roles for most adults in contemporary society. In that, work may be interrupted by family and family may be interrupted by work. Work often generates ambivalent feelings; it can create both positive feelings (e.g. gives energy, enables development) and negative feelings (e.g. lack of freedom). Therefore, most people accept the overall life experiences including the various dimensions or domains that play a role in work-personal life interaction, such as, time spent on one domain, pressures experienced, responsibilities carried, sense of loyalty with work and family, as common and conflicting aspects. Recent developments in boundary theory highlighted the fact that integrating, or rather interaction means bordering between the two domains of work and personal life is permeable. The main objective of this study was to investigate work-personal life interaction (WPLI) experiences of Setswana speaking police officials. This study also concentrated on the existence of work-personal life interaction, aspects involved, consequences thereof and coping mechanisms employed by the police officers. A non-probability purposive voluntary sample (n = 12) was taken of Setswana speaking police officials from the Mafikeng area in the North West Province. Data collection was done through a phenomenological method of semi-structured in-depth interviews. Content analysis was used to analyse, quantify and interpret the research data systematically and objectively. Results from the content analysis based on the experiences were recorded as reported. The results indicated that there was a definite interaction between work and personal life. However, some police officials experienced interaction more than others. Furthermore, they also experienced the interaction to be more negative than positive due to organisational stressors and the management style of the organisation. Consequently the participants experienced high levels of strain and difficulty when managing their time and dealing with the interaction between their work and personal lives. The time and strain difficulties induced a lot of conflict in their homes as well as their social lives. However, there were some police officials who experienced positive aspects in their lives regardless of the difficulties of being a police official. In addition, it was identified that they made use of coping mechanisms that acted as a buffer against negative experiences of WPLI. Recommendations were made for both the organisation and for future practice. / Thesis (M.A. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2008.

This study empirically investigates the direct and indirect effects of export promotion programs (EPPs) on firm export performance. Government export promotion programs normally define the premise for successful exporting activities of the corporate sector and play a key role in stimulating international business activities of firms (Cavusgil and Michael, 1990; Marandu, 1995; Seringhaus and Rosson, 1990). While the extant literature on export performance mostly neglected EPPs as an antecedent of export performance, the literature on export promotion fails to relate it to export performance. A very few researchers in this area have focused on a direct relationship between EPPs and firm export performance, however, no study has investigated the effect of EPPs on other determinants of export performance toward establishing any indirect relation between EPPs and export performance. This study attempts to develop and test a comprehensive model of firm export performance that investigates how EPPs directly and indirectly influence firm export performance. Theoretical foundations are drawn from internationalization process and resource-based theories as frameworks for the analysis of the study. The model integrates the use of EPPs, management perception of export market environment, export knowledge, export commitment, and export strategy that influence firm export performance and develops a number of hypotheses. Export promotion programs are classified into two categories according to their similarity of purpose- "market development", and "finance and guarantee" related programs. All other variables in the model are latent and are measured by a set of observed items. The model is tested on primary data obtained from a sample survey of exporting firms drawn from three major export oriented industries in Bangladesh. Structural Equation Modeling (SEM) techniques (in AMOS 5) are used to test the validity of the overall model and the relationship between variables hypothesized in the model. A two stage process is employed whereby the construct measurements are first evaluated, followed by an evaluation of the structural relationships. Analysis of the structural relationships supports most of the hypothesized relationships. The dimensions of export promotion programs are found to positively impact overall export performance. The research findings demonstrate that the use of market development-related export promotion programs influence firm export performance directly as well as indirectly through management perception of the export market environment, export knowledge and commitment. However, finance and guarantee-related export promotion programs indirectly influence export performance through export commitment. The study provides a guideline for managers of firms suggesting how they can benefit from EPPs in improving their positive attitude towards the export market environment, building their knowledge and enhancing commitment to exporting for better success in their international operations. This study provides guidelines to policymakers in designing and targeting export promotion programs effectively. The study also contributes to the literature by examining the indirect impact of EPPs on firm export performance. Finally, the limitations of the study are considered and possible directions for further research outlined.

Background. Despite extensive research the etiology of schizophrenia remains unclear. Whilst a substantial body of research points to a developmental component where early risk factors and maturational processes interact to culminate in psychosis during adulthood, key components and processes are yet to be confirmed. Prospective birth cohort studies, with their longitudinal data drawn from the general population, are vital to better understanding these pathways. To date, birth cohort (BC) studies have found that compared to healthy individuals, those who develop schizophrenia are more likely to display subtle deviations in certain developmental domains during infancy, childhood or adolescence. Yet there had been no recent review of these findings to identify areas of agreement, disagreement or where information was lacking. Aims. The overall aim of this dissertation is two-fold: firstly to identify and consolidate the current literature related to the antecedents of schizophrenia based on birth cohort studies; and secondly to undertake empirical studies based on an Australian birth cohort to address specific issues raised in the preceding review. Methods. The following three papers present empirical studies which use common methods based on an Australian birth cohort. Each study was based on a birth cohort of 3801 young adults born between 1981 and 1984, as part of the Mater University Study of Pregnancy and its outcomes. An extensive range of behavioural, cognitive, physical and social measures had been taken at various stages during their development namely, antenatally, at birth and six months, and at 5, 14 and 21 year follow-ups. Psychiatric diagnoses were obtained at age 21 follow-up from the Composite International Diagnostic Interview (CIDI), or, if this was not available, on a self-report health outcomes checklist; this produced the outcome variable ‘screen-positive non-affective psychosis’ (SP-NAP). The association between antecedents and later SP-NAP were examined using logistic regression adjusted for potentially confounding variables (such as actual age at assessment, cannabis use in adolescence, and gender). Each study also (a) examined differences in case vs. noncase maturation over time; and (b) conducted planned sensitivity and post hoc analyses, such as for source of diagnoses and predictive validity. Analyses were performed using SAS 9.2 (SAS). Results. The main findings of the review were that BC studies of schizophrenia provide important insights into both the maturational antecedents of schizophrenia and putative risk modifying factors. Yet while some antecedents, such as neurocognitive dysfunction, have been well documented, others are less certain (such as postnatal physical growth). There are no studies based on pre-morbid attentional measures. In addition, there were no studies of developmental pathways where continuity of maturation was based on within-individual scores rather than group means. These findings led to three empirical studies based on an Australian birth cohort previously untapped in psychosis research. The first study found that higher levels childhood and adolescent general psychopathology increased the risk of SP-NAP. This effect was less clear for females and when adolescent psychopathology had been rated by mothers at the 14-year follow-up. In contrast, self-reported hallucinations at the 14 year follow-up increased the risk of SP-NAP in both sexes. Males with high psychopathology scores in both childhood and adolescence were at greatest risk, followed by males and females whose ‘social, attention and thought’ scores were either consistently dysfunctional or worsened from childhood to adolescence (3- to 13-fold risk). The second study found that altered physical growth in infancy and adulthood (increased head circumference and height) raised the risk of SP-NAP for females but not males. For cases, there was no evidence of ‘catch-up growth’, i.e., growth retardation at birth being followed by a period of rapid growth. There was also no group difference in pubertal maturation for males or females. The final study found that dysfunction in childhood and adolescent intelligence, attention and speech increased the risk of SP-NAP for males but not females. Males with persistently high scores or who worsened on measures related to childhood and adolescent attentional problems were at greatest risk of SP-NAP. Discussion. While there are some caveats, disturbed developmental antecedents – particularly psychopathology and impaired cognition in males – were more frequently identified in cohort members who developed non-affective psychosis than their peers. More specifically, this disturbed development appeared be in domains which reflect those of the adult disorder and include the possible endophenotypes of psychosis-like experiences, inattention and visuospatial dysfunction. Of interest, self-rated items during adolescence were associated with increased risk of later psychosis. Finally, developmental pathways associated with non-affective psychosis were not uniform in timing but varied depending on such factors as domain and gender. These findings stress that understanding the heterogeneity in developmental pathways is crucial to understanding the heterogeneous nature of the subsequent disorder.

PURPOSE To explain what impacts brand love. METHODOLOGY Quantitative approach, using online surveys, with a total of 462 participants. Additionally, a qualitative method was applied in the pre-study, using semi-structured in-depth interviews, and a total of 12 respondents. FINDINGS Previous literature lack of concern for parallel studies has a divergent effect in explaining what impacts brand love. A consolidated approach can explain brand love antecedents as the combination of brand evaluation, brand identification, and experience value. In additional findings, brand category has a rather small influence in brand love, and, brand love is a phenomenon not exclusive to one particular brand category. LIMITATIONS The findings of this research account for 50% of explanatory power, further exploration and qualitative tests are needed in order to identify the remaining explanatory power. IMPLICATIONS The results of this research suggest a consolidated model that can be used by researchers to extend the understanding of what antecedes brand love. Additionally, the model is a starting point for avoiding future divergence in literature. For managers, the findings present a three-faceted suggestion on how to use brand love antecedents. ORIGINALITY This study consolidates a divergent field of study, and by doing so, creates a new understanding of what impacts brand love. Additionally, the pre-study has an unorthodox methodological approach, and uses a qualitative method as a screening process, rather than an exploration process.

We examine the moderating role of the situational and organizational contexts in determining unethical managerial behavior, applying the case-survey methodology. On the basis of a holistic, multiple-antecedent perspective, we hypothesize that two key constructs, moral intensity and situational strength, help explain contextual moderating effects on relationships between managers'; individual characteristics and unethical behavior. Based on a quantitative analysis of 52 case studies describing occurrences of real-life unethical conduct, we find empirical support for the hypothesized contextual moderating effects of moral intensity and situational strength. By examining these complex contextual moderators, we aim to contribute to organizational ethics research as we shed light on the critical role that context may play in influencing unethical managerial behavior.

Background: In the advent of multi-sided platforms defying traditional business models, sustaining long-term scale and success of platforms remains a great challenge to date. At the same time, customer engagement prevails as a superior factor enhancing customer loyalty in the current relationship marketing theory. Hence, utilizing customer engagement as a social tool to attract and sustain users could pose an appropriate answer for the struggles of platform businesses. Purpose: The purpose of this study is to validate context-specific relationships of customer engagement within a nomological network for multi-sided platform settings. By doing so, we particularly want to investigate context- specific antecedents in MSP settings leading to customer engagement and subsequently test its potential outcome of the continued use of the platform. Approach: By employing the pioneering example of Korea’s ubiquitous multi-sided platform KakaoTalk, we constructed a context-specific nomological network around customer engagement based on the platform’s perceived functionalities and characteristics. Applying structural equation modeling, we investigated our theorized path relationships between the major constructs of our research model. Findings: Our results suggested that the theorized context-specific nomological network around customer engagement can be validated in multi-sided platform settings. Hereby, customer engagement functioned as a strong predictor of user loyalty without being influenced by other relational constructs represented by relationship commitments. Additionally, a platform’s utility and especially its social experience embodied substantial factors that initially lead to customer engagement in the first place. Conclusion: Implications for this study contribute to both practitioners and scholars. While platform managers are guided with practical ideas to exploit customer engagement, the general literature of customer engagement is supported with a contextual study validating the applicability of the nomological network around customer engagement in the setting of multi- sided platforms.

Exit is an inevitable part of any business relationship. However, despite its importance, exit in buyer–supplier relationships is still a poorly understood phenomenon. Building on previous studies, this thesis addressed these concerns by empirically: a) identifying the economic and social antecedents that influence the exit decision; and b) validating how the antecedents of exit are related with the choice of exit strategies. To achieve these objectives, first, a systematic literature review was conducted to identify 82 studies that documented existing research on exit in buyer–supplier relationships. Second, informed by Transaction Cost Economics and Social Exchange Theory, a set of 88 testable hypotheses was developed and a survey captured data from 505 recently terminated relationships involving UK based firms. Finally, for data analysis, statistical techniques were employed including: a) analysis of variance; b) independent sample t–tests; c) multiple logistic regression; and d) multi–nomial logistic regression. The empirical findings of this thesis validated that: a) there are 8 economic and 14 social antecedents that influence the exit decision; b) lending support to extant research on exit, 57 hypotheses were accepted; c) 12 multiple logit models confirmed the relationship between a set of antecedents and exit strategies; and d) 6 multinomial logit models validated the relationship between a set of antecedents and a choice of one exit strategy over another. The results suggest that the influence of antecedents on the choice of exit strategies was subject to how the antecedents were analysed. The contributions of this research to Supply Chain Management literature are that we know now: a) which economic and social antecedents influence the exit decision; b) how individual antecedents affect exit strategies; c) how antecedents combine to affect exit strategies; and d) how antecedents combine to affect the choice of one exit strategy over another. This work provides an exit management tool box comprising a combination of data collection instrument, empirically derived framework and models that enables the managers to timely review the strength and weaknesses of their business relationships and their management processes.
