- Description: A comprehensive academic support at the public nursing college is important. Despite this, there is no such support in public nursing colleges in the Eastern Cape Province of South Africa. The aim of the study was to develop an academic support programme for students in order to improve their success in Higher Education. The study endeavoured to answer the following questions: What are the academic support needs of students at the public nursing college in the Eastern Cape of South Africa? What conceptual framework can be developed for the academic support programme of students? What academic support programme can be developed for students at the public nursing college? What guidelines can be developed for implementation of academic support programme of students? The objectives were: to describe academic support needs of students at the public nursing college in the eastern Cape Province of South Africa; to develop a conceptual framework for the academic support programme for students at the public nursing college in the Eastern Cape of South Africa; to develop an academic support programme for students at the public nursing college in the Eastern Cape in south Africa and lastly to describe guidelines for implementation and evaluation of the academic support programme. The research design used in this study was quantitative, qualitative, descriptive, evaluative, and theory generation. The study was conducted according to four phases. Phase one focussed on academic supports needs of the student. Phase two focussed on development of conceptual framework for the students at the public nursing college in Eastern Cape Province. Phase three focussed on the development of the academic support programme for the students, whereas phase four focussed on description of guidelines for implementation and evaluation of the academic support programme. The population of the study consisted of students undergoing training in a four-year programme at the Public Nursing College. The target population was the students in the same programme from level one to level four of training. The sampling technique used was a probability sampling with multi-stage and cluster sampling techniques being utilized. The total sample was n=333 participants. A quantitative self-developed questionnaire was used to collect empirical data. The questionnaire consisted of eight sections. Descriptive data was analysed using Statistic Package of Social Sciences (SPSS) version 24. Exploratory factor analysis was conducted on the descriptive data collected in phase one. Concept analysis and identification were done through the utilisation of exploratory factor analysis. The conceptual framework for the academic support programme was identified through the analysed factors. Fifteen factors were derived from the descriptive data. The conceptual framework of the academic support programme discussed in Chapter 5 was used also in the development of the academic support programme. It is in this chapter that assumptions, context, stakeholders, process, outcome, dynamics and, lastly, the recipient were discussed, along with a description of the programme. The programme was evaluated in accordance with the criteria for programme evaluation. The recommendations brought forward for the academic support programme were: The guidelines have to be tested for the implementation of the programme; benchmarking should be done to compare with other institutions of higher learning regarding their academic support programmes; an academic brochure regarding academic support must be available in the college and should be given to students on arrival as part of a package; and neutral researcher should conduct the same research in the same college.

- Description: This thesis focuses on the developmental impact of rural-urban migration in Nigeria. While, recognising the negative impact of rural-urban migration, the study argues that in order to benefit internal migrants as well as rural development, there must be a paradigm shift to focus on how the benefits of migration on development can be achieved. It is proposed that rural-urban migration occurs as a response to economic, education, health, social and environmental factors. The challenges confronting rural areas are urban bias development paradigm pursued by the successive governments resulting in rural underdevelopment that exacerbates the rural urban disparity. And the neglect of agriculture in rural areas resulting from the discovery of oil in Nigeria. The study revealed that flawed policies adopted by successive Nigerian governments led to joblessness, entrenched social inequality and opportunities. One of the outcomes of these short-sighted policies was rural underdevelopment, which accelerated rural-urban migration in Nigeria. However, the study also demonstrates that the income flows from the migrants to the various rural households has contributed to improvement in the living standard of the households. The fragmentary approaches to rural development that is currently the case in Nigeria would not generate the required level of development and growth needed in the rural communities to improve the living standard. Thus, there is need for a policy framework in Nigeria, which would encourage the private sector to play a vital role in contributing their part in the provision of infrastructural facilities in the rural communities. Although this thesis is a case study of the impact of rural-urban migration on rural development in Nigeria, it can serve to appreciate the role migration can play in promoting development both in rural and urban areas in Nigeria and other Saharan Africa countries.

- Description: Eight series of thirty (30) novel heteroleptic ruthenium(II) complexes were designed, synthesized and spectroscopically characterized, with the following general molecular formulae as [Ru(bdmpmar)(H2dcbpy)(NCS)]+, [Ru(bdmpmar)(vpdiinp)(H2dcbpy)]2,+, [Ru(bdmpmar)(vpbpp)(H2dcbpy)]2+,[Ru(H2dcbpy)2(N^)(NCS)]+, [Ru(H2dcbpy)2(N^)2]2+, [Ru(H2dcbpy)(N^)2(NCS)2], [Ru(H2dcbpy)(N^)(NCS)3]– and [Ru(vptpy)(H2dcbpy)(N^^^)]2+ where bdmpmar is a tridentate ligand of N,N-bis(3, 5-dimethylpyrazol-1-yl-methyl) aromatic organic compound (such aromatic organic compounds(Ar) are anthranilic acid, 4-methoxy-2-nitroaniline, aniline, toluidine, cyclohexylamine and anisidine), vpdiinp represents a monodentate ligand of 11-(4-vinylphenyl)diindeno[1,2-b:2’,1’-e]pyridine, vpbpp represents a monodentate ligand of 4-(4-vinylphenyl)-2.6-bis(phenyl)pyridine and vptpy represents a tridentate ligand of 4’-(4-vinyl)-2,2’:6’,2’’-terpyridine. Meanwhile, N^ represents any of the monodentate ligands of either vpdiinp or vpbpp and (N^^^) represents any of the monodentate ligands either of vpdiinp or vpbpp or NCS as disclosed in series VIII. The complexes were characterized by conductivity measurement, solubility, melting point, UV-Vis, PL, FTIR (ATR), NMR, Cyclic and square wave voltammetry. Nine chelating ligands, comprising of six (6) tripodal chelating ligands, two (2) vinyl monodentate ligands and one (1) vinyl tridentate ligand, were used for the synthesis of ruthenium(II) complexes ATR-FTIR spectra of all the ruthenium(II) complexes measured as solid samples, exhibited fine resolution IR bands in region between 3473-3438 cm-1 of carboxylic group in H2dcbpy. The bands in the range 3040-2950 cm-1 were ascribed to C-H bond stretching for the CH3 groups. The coordination of NCS group in the sphere of ruthenium(II) complexes related to series I, IV, VI VII and one compound of series VIII was investigated by ATR-FTIR spectroscopy. Bands in the range of 2116-2106 cm-1 and 777-770 cm-1 are ascribed to the respective N=C and the C=S bond stretching vibration which confirms the N-coordination of the SCN group. For all the complexes, the stretching vibration of Ru-N bonding was between 466 and 411 cm-1 due to coordination of the nitrogen atoms of the ligands to ruthenium central metal atom. The introduction of the two vinyl monodentate ligands (vpdiinp and vpbpp) in the coordination sphere of [Ru(bdmpmar)(vpdiinp)(H2dcbpy)]2+, [Ru(bdmpmar) (vpbpp)(H2dcbpy)]2+, [Ru(H2dcbpy)2(N^)(NCS)]+, [Ru(H2dcbpy)2(N^)2]2+, [Ru(H2dcbpy)(N^)2(NCS)2], [Ru(H2dcbpy)(N^)(NCS)3]– and [Ru(vptpy)(H2dcbpy)(N^^^)]2+ respectively, all related to series II, III, IV, V, VI, VII and two compounds of series VIII ruthenium(II) complexes, has been studied using the 1H and 13C NMR spectroscopy techniques. The 1H NMR spectra of series II-VII and the two compounds of series VIII of the ruthenium(II) complexes show multiplets in the aromatic region above 6 ppm due to the presence of either vpdiinp or vpbpp ligand, situated in different magnetic environment. However, no splitting pattern was observed in series I and part of VIII complexes possibly due to the absence vinyl monodentate subunits (vpdiinp and vpbpp) in series I and one of compound in series VIII ruthenium(II) complexes show no signals of complex splitting patterns. Carbon-13 NMR spectra data of series I to VIII ruthenium(II) complexes show most resonance signals range in the aromatic region of (δ 116.54-199.63ppm) corresponding to the molecular formulation of ruthenium(II) complexes incorporating 4,4-dicarboxy-2,2’-bipyridine, bdmpmar, vptpy, vpdiinp or vpbpp and NCS ligands respectively, depending on the intrinsic ligand variations. Carbon-13 NMR spectra data of series I, IV, VI VII and one compound in VIII show resonance peaks within the range 130-135 ppm are ascribed to NCS ligand confirming the presence of N-coordinated thiocyanate. Cyclic voltammograms of series I-IV and VI-VIII complexes display ruthenium-based oxidative peaks and the pyridines ligand-based reductive peaks. The redox behavior of complexes 4-12, 14-16, 18-20, 24-26 and 30 is dominated by the Ru(II)/R(III) redox couple in region (E1/2 between 0.53 and 1.18) and the pyridines ligand-based redox couples in the region between (E1/2 between −0.25 and −1.45). The photophysical property studies of the Ru(II) complexes are determined through the acquisitions of the absorption spectra, which tends to have profound effect on the short circuit current of DSSC. The absorption maxima were tuned by the introduction and variation of six (6) tripodal chelating ligands, two (2) vinyl monodentate ligands and one (1) vinyl tridentate ligand. From the studies, the results show that series IV, V, VI, VII and VIII complexes of molecular formula [Ru(H2dcbpy)2(N^)(NCS)]2+, [Ru(H2dcbpy)2(N^)2]2+, [Ru(H2dcbpy)(N^)2(NCS)2]2+, [Ru(H2dcbpy)(N^)(NCS)3]2+ and [Ru(vptpy)(H2dcbpy)(N^^^)]2+ respectively, have higher and multiple local absorption maxima near-IR region than the complexes of series I, II and III of molecular [Ru(bdmpmar)(H2dcbpy)(NCS)]2,+, [Ru(bdmpmar)(vpdiinp)(H2dcbpy)]2,+, [Ru(bdmpmar)(vpbpp)(H2dcbpy)]2,+respectively.

- Description: Let G be the cyclic group Zpn _ Zqm _ Zr where p; q; r are distinct primes and n;m 2 Z+. Using the criss-cut method by Murali and Makamba, we determine in general the number of distinct fuzzy subgroups of G. This is achieved by using the maximal chains of subgroups of the respective groups, and the equivalence relation given in their research papers. For cases of m, the number of fuzzy subgroups is _rst given, from which the general pattern for G is achieved. Murali and Makamba discussed the number of fuzzy subgroups of Zpn _ Zqm using the cross-cut method. A brief revisit of the group Zpn _Zqm is done using the criss-cut method. The formulae for _nding the number of distinct fuzzy subgroups in each of the cases is given and proofs provided. Furthermore, we classify the fuzzy subgroups of the group Zp1_Zp2__ _ __Zpn for p1; p2; _ _ _ ; pn distinct primes and n 2 Z+ using the criss-cut method. An algorithm for counting the distinct fuzzy subgroups of this group is developed.

- Description: The topic of social cash transfers is often viewed with scepticism. In the context of fragile states, questions of misuse, inaccessibility of social services, dependency and sustainability are often raised. This study sought to examine the transformative potential of social cash transfers on child wellbeing in fragile contexts through a case study of the social cash transfer pilot scheme in Bomi County of Liberia. The study specifically set out to to assess the relevance of cash transfers in the context of child wellbeing; determine how the wellbeing of child recipients of cash transfers had transformed; and analyse the determinants of the transformative effects of cash transfers on child wellbeing. The study adopted a quasi-experimental, mixed method, and cross-sectional research design. It utilised existing household survey datasets of the mid term and end term evaluations of the Bomi County pilot social cash transfer scheme conducted in Liberia in 2012 and 2015 respectively. A sample size of 224 (about 12percent of the sample frame) was used where Confidence Level was 95percent and P=0.5. This sample size was divided equally between households receiving cash (experimental group) and households with the same characteristics although not receiving cash transfers (control group). For the qualitative method, 66 participants were purposively sampled. A total of 34 participants participated in the indepth interviews, 32 children were sampled for focus group discussions. These were divided into 16 children from the experimental group and 16 children from the control group. Quantitative data sets were analysed in Statistical Package for Social Sciences (SPSS), and qualitative data was analysed through thematic analysis. The findings from the study provide a persuasive case for the transformative potential of social protection in fragile contexts. The study confirms the relevance of social cash transfers in promoting child wellbeing through empowering families to address children‘s physical and dependency-related vulnerabilities and institutional disadvantage. The study also confirms the transformative effects of social cash transfers on child health, food consumption, education, housing conditions, household assets, and child labour. In addition, the results indicate that social cash transfers mitigated gender based institutionalised disadvantage, created safe and protective environments for children and positively impacted on the local economy. However, the study also showed that, to a limited extent, social cash transfers had unintended impacts, particularly increase in child labour, where children were requested to sell in family petty businesses, and instances in which recipients misused the cash. The transformative effects of social cash transfers on child wellbeing were dependent on the size of the transfer, priorities in the use of cash, decision-making dynamics, and fairness of the selection process. The study proffers a Child Sensitive Transformative Social Cash Transfer Model based on the determinants of the impact of social cash transfer. The study ends by highlighting the critical role of social protection in infusing a transformative dimension to social work practice in fragile contexts, with a view to addressing equity, gender equality and child rights through confronting child vulnerabilities and institutionalised disadvantage.
