Although public relations is seen as a function that contributes to the greater good of society and the performance of an organisation (ref. Grunig, 2006b:3; Grunig, Grunig & Dozier, 2002:xii), the function does not, for various reasons, always deliver on this promise (ref. Gray, 2004:26–27; Grunig et al., 2002:166, 169, 192; Steyn, 2000c:40; Tobin, 2004:56; Van Ruler, 1997:248, 263; 2004a:123). Practitioners and professional bodies from various countries have researched, and tried to overcome the variables negatively influencing practitioners, through various methods. However, no study has provided a comprehensive prioritised list of all the variables influencing practitioners' contribution to organisational performance. In addition none of these actions has led to a sustainable solution for the profession where a critical mass of practitioners can keep the promise of contributing to the greater good of society and the performance of the organisation. In light of this problem, this study tries to understand how public relations practitioners can enhance their contribution to organisational performance, by examining the variables influencing practitioners in contributing to organisational performance. The study is framed within the relational, reflective, two–way symmetrical and feminist paradigms, supported by the general excellence theory as meta–theory, and the relationship management and corporate communication role theories. The multidimensional paradigm was specifically selected to accommodate the complex research context (Grunig, 1989:18; 2006a; Valin, 2004). From theory it was established that public relations contributes to organisational performance by assisting organisations to adapt to their changing environment by providing strategic information from the environment to the organisation that could reduce uncertainty in the organisation's strategic decision–making (Grunig et al., 2002:xi; Raupp & Van Ruler, 2006:18; Steyn, 2000c:27; Valin, 2004). Through this process the organisation's triple bottom line goals are aligned with the realities of the environment in which it operates (Moss et al., 2000:283; van Tonder & van Rheede van Oudtshoorn, 2006:149). This then creates long–term relationships with stakeholders that creates many benefits for the organisation (Grunig, 2006b:3, 6; Grunig et al., 2002:xi, 10, 11; Grunig & Haung, 2000:32; Hon & Grunig, 1999:7–9, 11; Phillips, 2006a:34, 35; 2006b:212). Within South Africa specifically, corporate communication practitioners perform the roles of strategist, manager and technician in order to complete the above tasks (Steyn, 2000b:1–42; 2000c:20–43). The research methodology followed to gather data to answer the General research question, is both exploratory and interpretive. The research started with a literature study, followed by semi–structured interviews with four purposefully selected practitioners and the chairpersons of the two professional bodies (PRISA and IABC) in order to verify the variables identified in literature, and possibly identify new variables pertaining to the South African environment. These variables, together with those identified in literature, were then used to construct a questionnaire completed by public relations practitioners active in the 1 319 top performing South African organisations as per South Africa's Top 300 National Companies List (Fletcher, 2007:1–330) and the Financial Mail Top 200 Companies List (Williams, 2005:1–168). A response rate of 19.9% was achieved. The qualitative data was content analysed and the quantitative data analysed by means of Statistica (StatSoft Inc., 2007) and SPSS (SPSS Inc., 2007) data analysis software. In order to determine the relationships between the variables influencing practitioners, structural equation modelling, by means of AMOS (SPSS Inc., 2009) software, was used. In essence it was found that practitioners should take ownership and manage the variables influencing their performance. Furthermore, 13 variables pertaining to the individual–, industry– and professional–levels were statistically verified as the most important variables influencing practitioners. Due to the specific relationship between these variables, it would seem that enhancing any of these 13 variables would enhance the practitioner's contribution to organisational performance. The main contribution of the study is to add to the discussion on the how the profession can manage its contribution to organisational performance by categorising and empirically verifying a list of all variables influencing practitioners' performance and by suggesting a model indicating the relationship between the most important variables influencing practitioners. / Thesis (Ph.D. (Communication Studies))--North-West University, Potchefstroom Campus, 2011.

Hierdie proefskrif handel oor 'n selfaktualiseringsbenadering tot bestuursukses binne 'n finansiele instelling. Die stand punt word gehuldig dat bestuurders wat reeds hoer vlakke van selfaktualisering bereik het oor die persoonlikheidskenmerke (intrapersoonlike, interpersoonlike en werkskenmerke) beskik wat tot bestuursukses lei. Hierdie standpunt, wat gegrond is op die uitgangspunte van die humanistiese benadering, is nog nie in finansiele instellings nagevors nie. Die volgende literatuurdoelstellings is in hierdie navorsing bereik: 'n Ge"integreerde beskouing van die vernaamste humanistiese persoonlikheidsteoriee, wat dien as metateoretiese raamwerk vir hierdie navorsing, is daargestel. - Die konsep selfaktualisering is omskryf en die persoonlikheidskenmerke van die selfaktualiserende persoon is ge"identifiseer. - Die konsep bestuursukses is omskryf en die persoonlikheidskenmerke van die suksesvolle bestuurder is ge"identifiseer. - Meetbare bestuursukseskriteria asook meetinstrumente vir die meet daarvan is ge"identifiseer. 'n Psigometriese toetsbattery is saamgestel uit die Algemene Gesondheidsvraelys, Verstandelike-helderheidstoets, Sestien-persoonlikheidsfaktorvraelys, Persoonlikeorienteringsvraelys, Rottervraelys, RGN Gevallestudietegniek-enbesluitnemingsvraelys en die Biografiese vraelys. Hierdie meetinstrumente is as klassifikasieveranderlikes gebruik om die meetbare komponente van die konstruk selfaktualisering by bestuurders van 'n finansiele instelling te meet. Besuursukses, as kriteriumveranderlike, is met die prestasiebestuurevaluering- en werknemer -effektiwiteitsvraelys gemeet. Uit die statistiese analise (meervoudigeregressie-analise) blyk dit dat 15 klassifikasieveranderlikes met bestuursukses verband hou. Die meervoudige korrelasie R (aangepas vir getal gevalle en getal klassifikasieveranderlikes) is gelyk aan 0,54. Daar is dus in hierdie navorsing 'n verband gevind tussen die konsepte selfaktualisering en bestuursukses soos gemeet by bestuurders van 'n finansiele instelling. Verskeie klassifikasieveranderlikes toon 'n paraboliese verband met bestuursukses. Dit dui daarop dat 'n relatiewe aanwesigheid of sterkte van spesifieke persoonlikheidskenmerke noodsaaklik is vir bestuursukses. lndien 'n sekere optimale punt egter oorskry word, het dit 'n nadelige effek op bestuursukses. Die gevolgtrekking word gemaak dat die evalueringstegnieke en psigometriese instrumente wat in hierdie navorsing gebruik is en wat 'n verband (reglynig of parabolies) met bestuursukses getoon het, binne die finansiele instelling gebruik kan word om bestuurders met bestuurspotensiaal te identifiseer. Aanbevelings is ten opsigte van die gebruikswaarde van die konsep selfaktualisering vir die praktyk en vir verdere navorsing geformuleer. / This thesis examines the self-actualisation approach to management success within a financial institution. The premise is that managers who have already reached high levels of self-actualisation possess the personality traits (intrapersonal, interpersonal and work traits) that lead to management success. This premise, which is based on the points of view of the humanistic approach, has not yet been researched in a financial institution. The following literature objectives were achieved in this research: - An integrated view of the major humanistic personality theories, which serve as metatheoretic framework for this research, has been compiled. - The concept of self-actualisation has been defined and the personality traits of the self-actualising person identified. - The concept of management success has been defined and the personality traits of the successful manager identified. - Measurable management success criteria as well as measuring instruments for measuring these criteria have been identified. A psychometric test battery has been compiled from the General Health Questionnaire, Mental Alertness Test, Sixteen Personality Factor Questionnaire, Personal Orientation Questionnaire, Rotter Questionnaire, HSRC Case Study Technique and Decision-making Questionnaire and the Biographical Questionnaire. These measuring instruments were used as classification variables to measure the measurable components of the selj-actualisation construct among managers of a financial institution. Management success, as a criterion variable, was measured using the performance management evaluation and employee effectiveness questionnaires. From the statistical analysis (multiple-regression analysis) it is evident that 15 classification variables relate to management success. The multiple correlation R (adjusted for number of cases and number of classification variables) equals 0,54. A relation has therefore been found in this research between the concepts of selfactualisation and management success as measured in managers of a financial institution. Several classification variables show a parabolic relation to management success. This indicates that a relative presence or strength of specific personality traits is essential for management success. However, when a certain optimal point is exceeded, this has a detrimental effect on management success. The conclusion is reached that the evaluation techniques and psychometric instruments used in this research, which showed a relation (whether rectilineal or parabolic) with management success, may be employed at a financial institution to identify managers with management potential. Recommendations in respect of the usefulness of the self-actualisation concept for the practical environment and for future research were formulated. / Industrial and Organisational Psychology / DCom (Bedryfsielkunde)

Job insecurity in the workplace has become an increasingly important trend in organisational research. The appraisal of job insecurity by individuals plays a significant part in how reactions manifest in the experiences of workplace stressors, job satisfaction, positive and negative work attributes and social support. However, there is a lack of research regarding specific workplace stressors at work leading to certain outcomes like safety behaviour, turnover intention and mental health, especially within a South African working context. Job insecurity has also been classified as a workplace stressor. The existence of other stressors tends to increase the ultimate effect of insecurity for the individual. The attempts from organisational management to manage this phenomenon are therefore crucial in decreasing the negative effects of job insecurity and increasing the productivity of the organisation. In order to measure the job insecurity levels of employees, it is important to make use of valid and reliable job insecurity measures. An absence of empirical research on validity and reliability studies in terms of job insecurity in South African is evident. The main objectives of this research were: 1) to establish the psychometric properties of a measure of job insecurity in a selected gold mining company in South Africa; 2) to determine the influence of job insecurity and work stress (i.e. role conflict, clarity and overload) on worker safety performance and if coping could moderate this; 3) to investigate the theoretical and empirical relationships between job stressors (task completion ambiguity and task quality ambiguity), competency demands, employability perceptions, job satisfaction and turnover intention over time, and 4) to investigate if social support has a mediating effect between positive interpersonal attributes, negative interpersonal attributes, job insecurity and subsequent health. To achieve the first objective, a cross-sectional design was used (N = 566), including various business units of a South African-based gold mining company. The assessment of the psychometric properties of a measure of quantitative and qualitative job insecurity for employees was determined through construct (structural) equivalence, exploratory factor analysis and multivariate analysis of variance to calculate the comparison of the factor structure for the different cultural groups. For qualitative job insecurity, the scale shows low equivalence for the African languages group. Statistically significant differences were found between the levels of job insecurity of employees in terms of gender. The second objective, concerning the investigation into the relationship of work stress and job insecurity with unsafe behaviour at work, was achieved with across-sectional survey design (N = 771). The hypothesised model included the influence of role conflict, role ambiguity, role overload, and job insecurity on unsafe work behaviour. Coping was introduced as a moderator in this relationship. The results indicated that when employees experience work stress and job insecurity, their safety compliance is low. This relationship was also moderated by a coping strategy of Avoidance. To achieve the third objective, a longitudinal study was conducted and data was gathered by means of an electronic survey, with 771 employees participating at Time 1, and 345 participating at Time 2. Results for predicting employees’ turnover intentions, experience of task completion and quality ambiguity, external employability and job satisfaction made a direct contribution in predicting their turnover intention. No mediating role of job satisfaction between job stressors, competency demands and employability perceptions on the one hand and turnover intentions on the other hand, were found. Addressing the fourth objective in investigating the moderating role of social support between the relationship of experiencing positive interpersonal (communication with the manager and feedback), negative interpersonal experiences (powerlessness and interpersonal conflict), job insecurity (quantitative and qualitative) and health, was met with a longitudinal random sample of employees in different business units in one selected multi-national mining company based in South Africa (N = 771). Results for these employees indicated that all the proposed variables, except feedback from the manager, were statistically significantly related to health. No moderating effect for social support could be found over time, but it was shown that interpersonal conflict at work is a longitudinal predictor of employee health. By way of conclusion, the implications of the research were discussed and recommendations for managers and for future research were made. / Thesis (PhD (Industrial Psychology))--North-West University, Potchefstroom Campus, 2013.
