Although student enrolment in South African universities has significantly increased, the retention and graduation rates remain low. One reason for the low student success is the lack of engagement in their studies. It is therefore very important for universities to determine the various predictors of student engagement. The aim of this study is to establish whether proactive behaviour towards strengths use, proactive behaviour towards deficit improvement and fit with study course have an impact on engagement. Universities need to focus on creating an environment in which students can actively use their strengths and develop their weaknesses for improved study fit and enhanced levels of engagement. The general objective of this research study was to test a structural model of proactive behaviour towards strengths use (PBSU), proactive behaviour towards deficit improvement (PBDI), fit with study course and engagement amongst first-year students, and to test the mediating effect of study course between PBSU/PBDI and engagement. This study was conducted in order to gain more knowledge and a better understanding of the antecedents of engagement amongst first-year students in South African. The Mplus and SPSS programmes were utilised for the statistical analysis of the data. A cross-sectional research design was used with a sample of 692 first-year students of a higher education institution in South Africa. The hypothesised model was tested by performing structural equation modelling. The bootstrapping method was used to identify possible mediating effects of fit with study course. The results confirmed a significant positive relationship between PBDI and engagement but no direct significant relationship between PBSU and engagement (although the significant levels were close to 0.05). The results also indicated a significant positive relationship with PBDI and engagement. PBDI was also found to be positively related to engagement. Furthermore, fit with study course fully mediated the relationship between PBSU and engagement and partially mediated the relationship between PBDI and engagement. After conclusions for the study had been drawn recommendations for the institution, students, as well as for future research were made. / MCom (Industrial Psychology), North-West University, Potchefstroom Campus, 2015

Positiv psykologi har influerat studier om att leva det bra livet. Forskning om karaktärsstyrkor för att öka välbefinnande har tillsammans med betoningen på social kontext bidragit till insatser för att främja ungdomars utveckling. En viktig faktor i ungdomars utveckling har visats vara deras insatser i skolan. Insatsen i skolan på gymnasienivå kan ha ett stort inflytande på introduktionen till vuxenlivet. Studien undersökte vilka relationer som finns mellan ungdomars sociala stöd, välbefinnande och självskattade skolinsats. Detta skedde utifrån tre hypoteser och en frågeställning. I studien deltog 212 gymnasieelever genom att svara på en enkät som bestod av EPOCH Measure of Adolescent Well-Being, Multidimensional Scale of Percieved Social Support samt frågor för självskattad skolinsats. Materialet undersöktes med korrelationer, t-tester och två regressionsanalyser. Slutsatsen var att gymnasieelevers kön, välbefinnande och sociala stöd till olika grad har betydelse för den självskattade skolinsatsen. Ihärdighet visade sig vara den starkaste prediktoren för hur ungdomar skattar sina skolinsatser.

The world of work has changed dramatically in the last decade and constant change has become the new normality. Employees are affected by possible re-organisation, retrenchments and downsizing which affects their behaviours and attitudes at work. Leaders have the responsibility of leading their followers through these difficult times to the best of their ability. A positive leader is seen as someone who recognises and focuses on the strengths and accomplishments of his or her employees. When a leader is positive and has a positive leadership approach, it may influence their followers’ feelings of psychological empowerment, work engagement and satisfaction with life. The objective of this study was to investigate the relationship between positive leadership, psychological empowerment, work engagement and satisfaction with life of employees in a chemical industry. A cross-sectional survey design was used with a convenience sample (n = 322). The measuring instruments used were the Positive Leadership Measure, the Measuring Empowerment Questionnaire, the Work Engagement Scale and the Satisfaction with Life Scale. Confirmatory factor analysis was used to test whether the measures of the constructs were consistent with the understanding of the nature of the constructs and to test whether the data fitted the hypothesised measurement model. Structural Equation Modelling (SEM) was used to examine the structural relationships between the constructs. The results show that there are statistically significant relationships between positive leadership, psychological empowerment, work engagement and satisfaction with life. Positive leadership has an indirect effect on work engagement and satisfaction with life via psychological empowerment. The implication of the results is that the work related aspects of positive leadership, psychological empowerment and work engagement has a positive effect on the non-work related aspect of satisfaction with life. Practical implications and directions for future research are offered. / MCom (Industrial Psychology), North-West University, Vaal Triangle Campus, 2013

Many homeless youth come from foster homes, group homes, and other forms of substitute care. For young people in the child welfare system, elopement represents a major problem as it places them at risk for a number of troubling outcomes. Three studies were undertaken examining elopement among young people living in substitute care in Canada and the United States. The first study explored strengths and needs in a sample of 5,011 children and youth housed in a variety of substitute care settings including foster homes, group homes, residential treatment centres, emergency shelters, and juvenile justice facilities. Results indicated that needs, but not strengths, predicted running among children, while both needs and strengths predicted running among adolescents. Problems with school attendance, substance abuse, and delinquency also predicted running among both children and adolescents, with the exception of young children, for whom substance abuse was not a significant predictor. The second study explored the relationship between trauma, strengths, and elopement in a sample of 2,296 adolescents living in substitute care. Sexual abuse, physical abuse, school violence, and traumatic grief/separation were found to predict elopement. In addition, family violence and community violence predicted running among younger but not older adolescents. Educational strengths predicted a lower risk of running away for all adolescents, while well-being and relationship permanence predicted a lower risk of running among younger and older adolescents, respectively. The impact of strengths on the relationship between trauma and elopement was evaluated, with results suggesting that elopement was not predicted by an interaction between strengths and trauma. The third study was qualitative in nature and explored the perspectives of youth who had run away from substitute care at least once in their lifetime. Youth provided information about their experiences as well as suggestions designed to reduce the prevalence of running away among youth in substitute care. Findings for all three studies were discussed in relation to the literature with implications for research and prevention.

The overall objective of this study is to develop and evaluate a social group work empowerment programme which is aimed at alcohol dependent elderly people's needs and strengths. The thesis consists of four sections: Section A refers to the problem statement, research objectives and procedures which were followed. Furthermore the limitations of this study, the definition of key words as well as the composition of the research report are discussed. The problem statement can be condensed as follows: o Journals all over the world have been pleading for decades that alcohol dependent clients should be exposed to special developed treatment programmes. Opposed to this, it was found that treatment centres in South Africa use one programme for all their clients, irrespective of age. This entails an unfair and unjust service delivery model. From these findings a need for a specialized treatment programme for alcohol dependant clients was identified. o The strengths perspective has been successfully implemented in various service areas of social work. Unfortunately it has not yet been implemented in a controlled study with alcohol dependent elderly through group work services. The problem statement leads to four research aims. Developmental and Utilization Research (DR & U-model) was used as the overall research model. This model was implemented within a mixed methodological design model. Interviews and experimental research were used as quantitative approaches, although some qualitative data were also reported. A case study, as a qualitative approach, was also used. Literature studies were conducted on the themes of alcoholism, social group work, as well as the strengths perspective. Section B consists of the four articles that form the report about the research outcomes. Each article is a report about a particular sub-project of the research and each has, as a self-contained unit, an own research aim, research method and report. Each of these is linked with the central aim, objectives and content of the umbrella research project. The four articles are: Article 1: Profile of alcohol dependent elderly people A comprehensive profile of alcohol dependent elderly is drafted based on the results of interviews and case studies with 56 aged participants. Various strengths, such as a spouse, of alcohol dependent elderly were identified. On the other hand needs, such as effective communication skills, were also identified. Article 2: The nature and practice of a strengths perspective with alcohol dependent elderly people The history of the strengths perspective is outlined within a South African and international context. From the literature study as well as interviews with the aged participants (N=56) and social work practitioners (N=27) various strengths and qualities group work services with alcohol dependent elderly people. Opposed to this, it was found that although this perspective holds many advantages for the alcohol dependent elderly person, it is presently not practised at registered treatment centres in South Africa that were involved in this investigation. Advantages, disadvantages and principles of this perspective are also discussed. Article 3: A social group work empowerment programme with alcohol dependent elderly people A social group work empowerment programme was developed for alcohol dependent elderly, aimed at their special needs, strengths and challenges. The programme was developed in the spirit of empowerment, a strengths perspective, healing and wholeness, as well as music therapy. Thirteen group meetings, such as communication, conflict management, handling of mild depression, managing of loss, HIV/Aids and the aged person, as well as religion and spirituality in old age, were developed and presented to the client group. Special concerns for group work with the aged, such as to use a loud voice and to speak clearly, were identified from the literature and empirical research, and was taken into account during the programme presentation. Article 4: The effect of a social group work empowerment programme on the social functioning of alcohol dependent elderly people The programme was implemented with eight (N=8) aged participants in an experimental group. Eight (N=8) aged participants was in a comparative group and they received the current group work programme offered by the targeted treatment centre. The shortened Affectometer 2 (Kammann & Nett) and Personal Multi-Screening Inventory (Perspective College) were used as quantitative measuring tools at four occasions with both groups. Added to that, the experimental group completed a self-developed qualitative questionnaire once after intervention. According to the quantitative data neither the empowerment programme, nor the current group work programme improved the social function of the alcohol dependent elderly people The qualitative data showed exactly the opposite findings for the experimental group. In Section C a summary of the findings and conclusions of the full research project is provided. Furthermore some recommendations are provided, followed by a discussion on the contribution of the study. Section D consists of various addenda, such as the interview schedules that were used for data collection purposes. The thesis is concluded with a compound bibliography. / Thesis (Ph.D. (Social Work))--North-West University, Potchefstroom Campus, 2006

South African organisations face the challenge of creating organisations that will engage employees in ways that allow for the optimisation of their strengths. This can be achieved by following a strength-based approach (SBA). An SBA aims to achieve optimisation of human functioning, where talents and strengths are the focus and weaknesses are understood and managed. Although previous research suggests that an SBA has positive influences on individual and organisational outcomes, no instrument exists within the South African context that measures employees’ perception of the extent to which they believe their organisation makes use of their strengths and talents. Recently, a new scale was developed to address this need. However, no studies have been done to see how well the items of this scale function. The objectives of this research were to 1) conceptualise an SBA according to literature, 2) determine whether the items in the SBA scale are unidimensional, 3) to determine the internal validity and reliability of the new SBA scale, and 4) make recommendations for future research. A cross-sectional quantitative research design was used whereby online and hardcopy versions of the questionnaire were distributed to participants. A sample of 699 participants was collected from the Gauteng and North-West provinces. Rasch analysis was used to determine the reliability and validity of the items. Acceptable item reliability was found. Both the item and person separation indices were acceptable. Mean infit and outfit indices for both person and item were acceptable. The seven-point frequency-based Likert scale worked satisfactorily overall, although categories 0, 1, and 2 were under-utilised. Finally, the infit and outfit statistics for all eight items functioned satisfactorily, except for one item. Recommendations are made for practice as well as for future research. / Thesis (MA (Industrial Psychology))--North-West University, Potchefstroom Campus, 2012

We present revised measurements of the static electric dipole polarizabilities of K, Rb, and Cs based on atom interferometer experiments presented in [Phys. Rev. A 2015, 92, 052513] but now re-analyzed with new calibrations for the magnitude and geometry of the applied electric field gradient. The resulting polarizability values did not change, but the uncertainties were significantly reduced. Then, we interpret several measurements of alkali metal atomic polarizabilities in terms of atomic oscillator strengths f(ik), Einstein coefficients A(ik), state lifetimes tau(k), transition dipole matrix elements D-ik, line strengths S-ik, and van der Waals C-6 coefficients. Finally, we combine atom interferometer measurements of polarizabilities with independent measurements of lifetimes and C-6 values in order to quantify the residual contribution to polarizability due to all atomic transitions other than the principal ns-np(J) transitions for alkali metal atoms.

The purpose of this study is to explore the important factors that affect graduate employment such as human capital, social capital and university career services. It focuses on the graduate labour market in the UK and uses mixed methods. While quantitative data derive from a survey, qualitative data come from interviews and secondary sources in a case study. The survey includes 947 university graduates and qualitative data consist of 8 interviews, internal and external reports. The findings show that the level of human capital and social capital affect the way graduates find a job and the use of social capital in job searches varies by ethnicity, age and academic level. However, gender and academic discipline do not affect the use of social capital in the UK graduate labour market. Moreover, the study shows that university career services can play an important role in job searches. Overall, however, direct application and online career services are two most widely used methods to find a job. The originality of the research is twofold. Firstly, it illustrates the relationship between two important components in graduates’ job search processes: human capital and social capital. Secondly, it examines the role of an institution: university career services and displays the importance of institutional approaches in building a bridge between students and employers.

Synchronization of an ensemble of oscillators is a phenomenon present in systems of different fields, ranging from social and physical to biological and technological systems. The most successful approach to describe how synchrony emerges in these systems is given by the Kuramoto model. This model as it stands, however, assumes oscillators of fixed natural frequencies and a homogeneous all-to-all coupling strength. The Kuramoto model has been analytically discussed to address the synchronization phenomena of coupled oscillators in the thermodynamic limit (N --> ∞). However, there needs to be a modi cation to address the inevitable in uence of external fields on the pattern of various real life synchronization phenomena which, in general; involves a finite number of oscillators. This research introduces a time dependent coupling strength K(t) which is from the modulation of external elds in the form of, for example, a periodic impulse, in the nite oscillators assembly. A sinusoidal function with some arbitrary values of amplitude and frequency is added to the fixed coupling strength as a perturbation of external elds. Temporal evolution of order parameter r(t) and phase θ(t), both of which measure the degree of synchronization of an assembly of oscillators simultaneously, are compared between uniform and time dependent cases. Graphical comparison are made using a 2 oscillator system, a building block of any finite oscillators case. Also, similar comparisons are performed for a system of 32 oscillators which are chosen randomly as a representative of a nite number of oscillators (2 < N < ∞). A temporal variation of the relative phase angle θ(t) = θ2(t) - θ1(t) in 2 and 32 oscillators systems using uniform and time dependent cases is also a part of this research. This work also introduces a time-dependent coupling strength in the form of a step function. The main objective of using such a function is to keep the synchronized behavior of the oscillators persistently. This behavior can be achieved with the perception that occasional boosting with higher coupling strength K(t) should be enough to sustain synchronous behavior of oscillators which, in general, are tuned with lower K(t). / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2018. / FAU Electronic Theses and Dissertations Collection
