- Description: The synthesis of graphene quantum dots (GQDs) using organic compounds as carbon sources via bottom-up approaches has been widely developed, whereas their hybrids with other materials have been previously achieved post-synthetically via multi-step procedures. A novel approach for the preparation of supramolecular hybrid conjugates of GQDs and phthalocyanines (Pcs) via an in situ one-step bottom-up route was employed in this study. The as-synthesized GQDs and their Pc conjugates were characterized using different spectroscopic techniques and their photophysicochemical properties evaluated. Notably, the singlet oxygen quantum yields of the Pcs in the presence of GQDs were found to be 0.51 and 0.74 for 1-GQDs and 2-GQDs, respectively, as compared to the Pcs alone (0.18 and 0.70 for complex 1 and 2, respectively). The increase in triplet quantum yield (ΦT) values is complemented by a decrease in fluorescence quantum yield (ΦF). ΦT value of 0.96 obtained for the complex 2 after conjugation with GQDs is better or higher than the value of 0.74 as reported in the literature when complex 2 was conjugated to semiconductor QDs. Hence, this novel approach resulted in the derivation of hybrid materials with potentials for various photophysicochemical applications such as photodynamic therapy and photocatalysis.

- Description: Online appendix to the authors’ paper published in Social Indicators Research under the title: ‘The Best and Worst Times of Life for South Africans: Evidence of universal reference standards in evaluations of personal well‐being using Bernheim’s ACSA’. From the introduction: The Anamnestic Comparative Self‐Assessment (Bernheim’s ACSA), a measure of personal well‐being, was applied in the 10th annual round of the nationally representative South African Social Attitudes Survey (SASAS), a research infrastructure that has been administered by the Human Sciences Research Council (HSRC) since 2003. The target population for the survey was individuals aged 16 and over who live in South Africa. The multi‐stage sampling frame used by SASAS is based on census enumerator areas and data is weighted to the South African population using Statistics South Africa’s mid‐year population estimates as a benchmark. A total of 2’521 persons were interviewed in October and November 2012 by trained fieldworkers in their homes. Each interview was conducted in the respondent’s home language. ACSA was translated into the eleven official national languages. The SASAS 2012 study of ACSA follows on two earlier South African studies conducted in the Eastern Cape Province: a small pilot study conducted in 2005/6, followed by a larger representative community survey with some 1’000 respondents in 2007. ACSA uses a self‐anchoring scale. SASAS 2012 survey respondents were asked to think, first of their best period in life, and then of their worst period in life. These two periods represent the anchors of an 11‐ point scale running from ‐5 over a mid‐point (0), to +5. Text placed above the negative ‐5 anchor of the scale read: ‘As bad as the WORST period in my life’; text above the positive +5 anchor read: ‘As good as the BEST period in my life’. The respondents were asked to rate their present well‐being relative to these two periods on the scale. Their descriptions of these two extreme periods were recorded verbatim at the time of the interview. Later they were classified by domain in life based on the guidelines for the standard multiple‐choice format provided for recording ACSA anchors. This classification system is recommended by the ACSA scales’ initiator, Jan Bernheim and his colleagues. This online appendix to our Social Indicators Research article (‘The best and worst times of life for South Africans: Evidence of universal reference standards in evaluations of personal well‐being using Bernheim’s ACSA’) reports in greater detail the substantive contents of the survey responses to the ACSA anchoring process. The anchors of the ACSA scale serve as the reference standards for evaluating one’s life. Importantly, our 2012 SASAS survey respondents were invited to make explicit their choice of reference standards when reviewing their lives. This data offers a unique opportunity to gain rich insights into what matters for South Africans when they think about their quality of life and personal well‐being.

- Description: The optical limiting (OL) properties of 3,5-dipyrenylvinyleneBODIPY dyes that contain both electron withdrawing and donating moieties have been investigated by using the z-scan technique at 532 nm in the nanosecond pulse range. The extension of the π-conjugation at the 3,5-positions with pyrenylvinylene groups results in a ca. 200 nm red shift of the main BODIPY spectral band to ca. 700 nm, so there is relatively weak absorbance at 532 nm under ambient light conditions. Reverse saturable absorbance (RSA) profiles are observed in response to incident pulsed laser light that is consistent with a two photon absorption-assisted excited state absorption (ESA) mechanism in CH2Cl2 solution and when the dyes are embedded in poly(bisphenol carbonate A) (PBC) polymer thin films. This demonstrates that 3,5-divinyleneBODIPY dyes are potentially suitable for use in OL applications, since limiting threshold fluence (Ilim) values of below 0.95 J cm−2 are observed when thin films are prepared.

- Description: Novel pentadecylphenoxyl substituted homoleptic sandwich–type metallophthalocyanines: bis (complexes 2 and 4 containing Eu and Dy, respectively) and tris (complexes 3 and 5 containing Eu and Dy, respectively) 2,9,16,23–tetrakis–(3–pentadecylphenoxyl) phthalocyanines and cadmium based (Ag–CdSeTe/ZnTeSe) nanocrystals (NCs) were synthesized. The nonlinear optical (NLO) behavior of the metallophthalocyanines and their composites with NCs were investigated using the open aperture Z–scan technique at excitation wavelength of 532 nm with 10 ns pulse. All of the samples exhibited interesting NLO attributes: among all the sandwich–type complexes, complex 5 afforded the most efficient NLO features accounting for large nonlinear absorption coefficient (βeff) value of 3500 cm/GW and limiting threshold (Ilim) value of 0.43 J cm−2. Overall, the composites of the triple decker sandwich–type complexes with Ag–CdSeTe/ZnTeSe yielded the best NLO characteristics with 3 and 5 accounting for the largest βeff value of 5500 cm/GW and Ilim value of 0.09 J cm−2. The synthesized complexes and their composites with NCs could be viable and efficient NLO absorber due to their interesting NLO activities.

- Description: We report the dosimetric features of ultra-high molecular weight polyethylene (UHMWPE) using luminescence optically stimulated using 470 nm blue light. Samples irradiated to between 1 and 1000 Gy produces luminescence that increases with irradiation dose to produce a linear dose response between 1 and 1000 Gy. The sample was determined not to be affected by pre-dose in tests using a pre-dose of 4000 Gy. This characteristic precludes the need for elaborate background erasing routines typical of dosimetry experiments. The signal has good reproducibility. We used this property to test recovery of ‘unknown’ doses with encouraging results. It was observed that luminescence can also be stimulated using 870 nm infrared light. The dose response, fading, pre-dose effect and the ability to optically stimulate luminescence from the polymer is discussed in terms of curing involving free-radicals.

- Description: The concept of Quality by Design (QbD) was introduced as a method of building quality into the product during the initial stages of manufacturing. This study explores the suitability of utilising QbD to optimise a legacy product. With the aid of QbD, a higher level of quality assurance and product knowledge was achieved. Sound scientific and risk-based decisions allowed for a robust manufacturing process with inherent operational quality and flexibility. By the establishment a quality target product profile (QTPP) and determining the influence of the critical processing parameters (CPP's) on the product's critical quality attributes (cQA's) the process understanding of Product X can be more accurately defined. The relationships between several explanatory variables will be explored by using a sequence of Design of Experiments (DoE) to obtain an optimal response. The DoE were performed and analysed using Minitab® statistical software version 17.0 (Minitab Inc., United Kingdom). A Response Surface Methodology (RSM) using a central composite experimental design (CCD) was utilised to capture the data. The data was analysed using the collection of statistical models (ANOVA) to analyse the differences between the means and their associated procedures. Input variables investigated were: compression machine tooling shape, hardness, and loss on drying LOD (post drying). The significant value (α) of 0.05 helped to determine if the null hypothesis would be accepted or rejected. The DoE identified the factors that had the highest risk of affecting the output variables and helped to establish the design space. Post completion of the DoE, a confirmatory batch was made which served as a diagnostic tool for evaluating the effectiveness of the generated model. The establishment of a strategy to control the variables and responses is of critical importance in order to appropriately use the flexibility given to products developed or optimised using QbD principles. This study show that the structured approach used in Quality by Design methodology can be successfully applied to optimise a commercialised legacy product.

- Description: X-ray request forms are used at hospitals and primary health care centres (PHCC) by health care professionals (HCP) to communicate with radiologists and radiographers when referring patients for ionising radiographic (x-rays) examinations. The x-ray request form and the radiological report are medico-legal documents. However, the importance of adequately completed x-ray request forms, appear to be underestimated. The HCP must write a brief clinical history on the x-ray request form that justifies the ionising radiographic (x-ray) examination referral, enabling radiographers and radiologists to have a better understanding of the patient’s clinical condition. An adequately completed x-ray request form assist the radiographer to make decisions regarding patient safety techniques and standard operating protocols that need to be applied. The radiologist will also have a better understanding of the patient’s clinical condition when reporting on the x-ray projections based on the clinical information supplied on the x-ray request form. The primary objective of this study was to explore and describe the adequacy of completion of x-ray request forms in order to optimise ionising radiographic referrals (x-ray requests) to ensure patient safety during ionising radiographic examinations at PHCC’s in NMBHD. A quantitative research design with an explorative, descriptive, and contextual approach was undertaken. The data was collected using an evaluation form checklist that the radiographer responsible for the requested x-ray examination completed. Data was gathered at all five PHCC’s, offering x-ray services, in the NMBHD by qualified radiographers evaluating the adequacy of completion of the x-ray request forms using an evaluation form checklist with an online program QuestionPro. Strategies to ensure validity and reliability in the study were undertaken. Ethical principles adhered to included informed consent, privacy, anonymity and confidentiality, gaining ethical permission to do the study and approval to enter the research site. The results of the study revealed that none of the 582 x-ray request forms evaluated were adequately completed. The fields on the x-ray request forms that were most frequently completed were the surname, clinical history, examination requested and the referring HCP details all had a total percentage correct completion of 90% and above. The fields most frequently omitted were last menstrual period (LMP) of females of child-bearing age and an indication of previous x-rays. The patient’s age and how to address the patient were also frequently incomplete. The researcher made recommendations to the NMBHD on how the x-ray referral system by means of the x-ray request form could be optimised of in order to increase patient safety during ionising radiographic (x-ray) examinations. Recommendations made to the Nelson Mandela Bay Health District (NMBHD) was based on the findings of the research study to ensure optimisation of x-ray requests concerning the completion of the x-ray request forms to ensure patient safety during x-ray examination procedures. Recommendations to the NMBHD were as follows:Education and training, Distribution of guidelines, Keeping a record of HCP’s qualifications, Consent form must be completed for all female patients of child-bearing age, Redesign the current x-ray request form. The researcher also made recommendations for possible future studies which could also increase patient safety during x-ray examinations and were as follows. The researcher suggested that this research could be applied at both public and private hospitals as well as in other health districts in the Eastern Cape to evaluate the adequacy of the completion of the x-ray request forms in the Eastern Cape. The researcher suggested a research study be done at PHCC’s in NMBHD, on the justification and the dose levels used for the frequently requested x-rays. The researcher recommended an accessible health information exchange system for radiography in Port Elizabeth and surrounding health institutions to reduce repeated x-ray requests for patients who visit different health institutions for the same clinical problem. The researcher concluded from the results of the statistical analyses of the study that generally the adequacy of completion of the x-ray request forms at the PHCC’s in NMBHD was average. Improperly or incomplete fields on the x-ray request forms were observed from the results. Indicating that referring HCP’s at the PHCC’s of NMBHD could optimise the x-ray referral system by means of correct, accurate and comprehensive completion of the x-ray request form to ensure patient safety during ionising radiographic examinations.

- Description: Dye-sensitized solar cells (DSSC) were fabricated by incorporating graphene materials as catalysts at the counter electrode. Platinum was also used as a catalyst for comparison purposes. Different phthalocyanines: hydroxyl indium tetracarboxyphenoxy phthalocyanine (1), chloro indium octacarboxy phthalocyanine (2) and dibenzoic acid silicon phthalocyanine (3) were used as dyes. Complex 3 gave the highest power conversion efficiency (η) of 3.19% when using nitrogen doped reduced graphene oxide nanosheets (NrGONS) as a catalyst at the counter electrode, and TiO2 containing rGONS at the anode. The value is close to 3.8% obtained when using Pt catalyst instead of NrGONS at the cathode, thus confirming that NrGONS is a promising candidate to replace the more expensive Pt. The study also shows that placing rGONS on both the anode and cathode improves efficiency.

- Description: The importance of human resources has been highlighted by many academic studies in recent times. This increase in interest has been a result of evidence that shows that employees contribute significantly to an organisation’s ability to gain a sustainable competitive advantage as well as to achieve increased efficiencies. It is therefore imperative that organisations retain this valuable asset to prevent the negative outcomes associated with high employee turnover. A high level of employee turnover tends to be exacerbated when these employees happen to be part of the core employees within the business. The organisation that motivated this study experienced an unacceptable level of core employee turnover. This study therefore aimed at identifying the organisational factors that influenced core employee turnover and in doing so, also ascertaining what relationship existed between these factors. The factors identified in the study were employee engagement, HRM practices, organisational culture, organisational support and organisational structure. These factors were uncovered and discussed by conducting a thorough review of the literature available on the subject. The literature review not only revealed the benefits associated with these factors, but also showed that the absence of these organisational factors has a negative influence on employee turnover. The study also utilised quantitative methods to collect and analyse data from respondents in the selected organisation. This focused on their opinions regarding the relationship between the various organisational factors and turnover intention. The data obtained indicated that all of the independent variables identified displayed a linear negative relationship with turnover intention and it could therefore be concluded that negative perceptions on employee engagement, HRM practices, organisational culture, perceived organisational support and organisational structure all had a negative impact on turnover intention. It was also noted that perceived organisational support displayed the strongest negative relationship with turnover intention. Consequently it can therefore be recommended that in order for organisations to retain core employees, it is necessary to develop robust systems that address employee needs on employee engagement, HRM practices, organisational culture, organisational support and organisational structure. A further recommendation made is that careful attention should be given to developing employee perceptions on organisational support, as the results showed that this is the most important factor in influencing core employee turnover behaviour.

- Description: Aesthetics was never a subject or a separate philosophy in the traditional philosophies of black Africa. This is however not a justification to conclude that it is nonexistent. Indeed, aesthetics is a day to day affair among Africans. There are criteria for aesthetic judgment among African societies which vary from one society to the other. The Yorùbá of Southwestern Nigeria are not different. This study sets out to examine how the Yorùbá make their aesthetic judgments and demonstrate their aesthetic philosophy in decorating their orí, which means head among the Yorùbá. The head receives special aesthetic attention because of its spiritual and biological importance. It is an expression of the practicalities of Yorùbá aesthetic values. Literature and field work has been of paramount aid to this study. The study uses photographs, works of art and visual illustrations to show the various ways the head is adorned and cared for among the Yoruba. It relied on Yoruba art and language as a tool of investigating the concept of ori and aesthetics. Yorùbá aesthetic values are practically demonstrable and deeply located in the Yorùbá societal, moral and ethical idealisms. It concludes that the spiritual importance of orí or its aesthetics has a connection which has been demonstratively established by the Yorùbá as epressed in the images and illustrations used in this paper.

- Description: One of the functions art serves is to visually document history for generations to come. Even with the development of writing, the artists have continued to document various aspects of what they encounter in their various communities. In Nigeria with particular reference to painting, several artists have used their paintings as visual documentaries. The introduction of the camera as a tool for documenting did little to dissuade these painters from continuing this role. This paper therefore examined selected paintings of artists in Nigeria, whose works reveal historical evidences and culture of a people. Paintings cutting across the various genres such as portraits, landscapes scenes, architecture, festivals and cultural issues from pre-independence Nigeria to the present were selected for examination and analysis. The paper explores a descriptive and comparative analysis of the selected paintings vis-à-vis the various subjects they have recorded. It concludes that these paintings show significant historical evidences that can be used to reconstruct history and others aspects of the society where the need may arise. Painters in Nigeria more than other artists have been able to record history with their works because of the pictorial and compositional peculiarity of painting as an art form.

- Description: The Yorùbá courtyard is an important architectural space in traditional Yorùbá architecture that has not received adequate scholarly attention. This paper examines the courtyards in the palace of certain chiefs and Ọwá Obòkun in Iléṣà, in southwest Nigeria. Fieldwork identified about ten courtyards in the palace of the Ọwá, four in the Rísàwè palace, and two in the palaces of the Léjọkà and Ọdọlé of Iléṣà. It uses these courtyards as models for courtyards in Yorùbá architecture. The study revealed that most of the courtyards in the Ọwá’s palace are generally not used for one specific function, though some are used mainly for religious purposes. The courtyards in the palaces of the chiefs are more functional, and better maintained than those of the Ọwá’s palace. The paper concludes that—considering their ancient and social function—the courtyards form a melting point within Yorùbá architecture. It suggests that efforts be made to ensure that the existing courtyards in these palaces are designated as landmark architecture and properly cared for to serve as tourist attractions.

- Description: Family businesses play an important role worldwide and in South Africa, in terms of their economic contribution and their ability to create jobs. However, the unwillingness of next generation family members (NGFMs) to join the family business seriously jeopardises its long-term survival. This is a matter of great concern for family business owners who in general have a strong desire to pass on the business to the next generation and to preserve the family’s legacy. Of the many factors relating to a person’s choice of career, parents are by far the most influential. Against this background, the purpose of this study was to gain a better understanding of the influence that parents have on the NGFM’s intentions to join the family business as well as the factors that moderate this influence. Establishing how parents influence an NGFM’s intention to join the family business makes an important theoretical contribution to family business, succession and entrepreneurial literatures, and holds both practical and theoretical relevance. The literature review provided an overview of the field of family business and discussed the nature of these businesses. Several frameworks, theories and perspectives relating to family businesses were elaborated on. The important role that family businesses play in the economies of countries and the unique challenges they face were highlighted. One of the most important challenges facing family businesses is that of transgenerational succession and the willingness of the next generation to make the family business their career choice. Several behaviour and career choice theories were discussed, particularly in relation to the South African context, and a summary of all the factors influencing career choice in terms of these theories was presented. Several parental influences on career choice were identified and examined in detail, namely Parent–child relationship, Parents’ job characteristics, Parental financial security, Parental job satisfaction, Parental identification, Parental expectations, Parental support and Parental style. Additionally, the influence of each parental influences on NGFMs, in a family business context, was highlighted. Based on anecdotal and empirical support, these parental influences were hypothesised as influencing the dependent variable in this study, namely Intention to join the family business. Based on the social cognitive career theory, Self-efficacy and Outcome expectations were hypothesised as moderating the aforementioned relationships. This study adopted a positivist research paradigm and a quantitative methodological approach that was deductive in nature. The methodology adopted to collect primary data was a cross-sectional analytical survey. A structured questionnaire was distributed to respondents who were identified by means of judgemental sampling and 453 completed questionnaires were subjected to statistical analysis. The validity of the scales measuring the dependent, moderating and independent variables was assessed by means of factor analysis and the reliability thereof by calculating Cronbach’s alpha coefficients. Both descriptive and inferential statistics were calculated. Multiple regression analysis (MRA) was used to assess the hypothesised relationships. The findings show that only one third of the respondents agreed that they had Intentions to join the family business. Furthermore, the results of the MRA reported significant and positive relationships between the independent variables Parental expectations, Perceived parental outcomes, and Parental identification, and the dependent variable Intention to join the family business. The results of the moderated regression analysis revealed that Self-efficacy and Outcome expectations do not moderate the relationships between all the parental influences investigated and Intention to join the family business as hypothesised. However, a significant positive relationship at the ten per cent confidence level was reported between the interaction effect, Self-efficacy x Perceived parental outcomes, and Intention to join the family business. A significant positive relationship at the five per cent confidence level was also reported between the interaction effect Outcome expectations x Parental identification, and Intention to join the family business. Based on the findings of this study, numerous recommendations were made. This study makes a contribution to both theory and practice. In terms of theory, the results have highlighted the applicability of both the theory of planned behaviour and the social cognitive career theory in explaining an NGFM’s Intention to join the family business. In addition, the applicability of these theories in the family business context has been confirmed. This study also contributes to the family business literature in that it provides new insights into how parents influence one of family businesses’ biggest challenges, namely their children not wanting to take over the family business. In terms of practice, the findings show that that several of the parental influences investigated do indeed increase the intention of NGFMs to join the family business. It is anticipated that these findings will encourage parents who own family businesses to take note of how they influence their children’s decision whether to join them in the family business, and ultimately to contribute to its possible long-term survival and success.

- Description: This investigation springs from the realization that academic achievement is influenced by different environmental factors. The influence of parental involvement on learners’ academic achievement has been recognized globally by experts in the education industry. As integral as parental involvement is, education industry is yet to come to terms on the best type of parental involvement needed for the teaching and learning of Mathematics in high schools especially at the transition phase. The aim of this study was to establish the relationship between parental involvement and grade 8 learners’ academic achievement in Mathematics. Quantitative research method was used for data collection. The data was collected with the use of parental involvement questionnaire for learners (PIQL) and learners Mathematics academic achievement scores. The research was conducted in six schools (public and private) within the East London Education District. The total sample size was 460 Grade 8 learners who were randomly selected across the board. The outcomes of the investigation revealed that parental involvement enhances the academic achievement of grade 8 learners irrespective of a definition of it or the measure of achievement. Furthermore, the results of this findings indicate that good parenting styles, parental support and parental educational background (r = 0.54; P < 0.05), (r =0.20; P< 0.05), (r = 0.68; P < 0.05) respectively are prerequisite for learners’ academic achievement in mathematics, showing that the variables are significantly related to learners academic achievement in mathematics; while parental involvement in the area of communication and family structure were very weak (r = 0.05; P > 0.05), (R=0.09; R2=.005; P < 0.05). This study therefore, recommended that parental involvement should be beefed up especially in areas of communication and family structure, by both the parents and teachers in order to enhance learners’ academic achievement in Mathematics.

Furthermore, the results of this findings indicate that good parenting styles, parental support and parental educational background (r = 0.54; P < 0.05), (r =0.20; P< 0.05), (r = 0.68; P < 0.05) respectively are prerequisite for learners’ academic achievement in mathematics, showing that the variables are significantly related to learners academic achievement in mathematics; while parental involvement in the area of communication and family structure were very weak (r = 0.05; P > 0.05), (R=0.09; R2=.005; P < 0.05). This study therefore, recommended that parental involvement should be beefed up especially in areas of communication and family structure, by both the parents and teachers in order to enhance learners’ academic achievement in Mathematics.

- Description: While parental involvement in homework is significant, few parents are able to assist in rural communities. The purpose of this study was to investigate the way parents and/or caregivers in rural communities are involved in the homework of their children. The main question was to find how parents in rural communities get involved in homework. The study adopted an interpretive paradigm, a qualitative approach, and a case study design to guide data collection and interpretation. Data was collected in two public combined schools in the King William’s Town District of the Eastern Cape Department of Education (ECDoE). One-on-one semi-structured interviews were used to collect data from parents, educators and principals whilst focus group interviews were used with learners. Documents were collected for background context of the schools. Documents collected include the school journals, learner portfolios, staff establishment, and school timetable. Schools were chosen purposefully because of their rural context and convenience to the researcher. Purposive sampling was also used in the selection of participants. To enhance the trustworthiness of the study, data sources were triangulated, participants were allowed to use their own language, data was mechanically recorded and transcribed and verbatim quotes were used in analysing data. The study found that all participants in both schools supported the need for parents to be involved in homework. Educators, largely, had a pessimistic view about parents; they felt that the parents do not meet their expectations in terms of assisting learners with homework. The study found that although parents see the need for their involvement in homework, in reality they are not always involved. Those parents who are able to assist with homework use a variety of strategies like assisting with the actual homework, referring their children to those who can assist, monitoring and supervising, assisting financially, and organising infrastructure. The study also found that there are several challenges facing parents in rural communities that hinder them from assisting optimally. These include negative attitude towards homework, lack of subject knowledge, irresponsibility, lack of finances and material resources, community commitments, not having enough time, family responsibilities, lack of commitment by learners, and homework overload. These challenges suggest that many parents in rural communities may not be able to provide the necessary leadership for modelling purposes to learners. This can be attributed to several exogenous and exogenous factors that have an impact on homework completion by learners. This study, in addition, found that participants have a good sense of what can be done to improve parental involvement in homework. These include the revival of Adult Basic Education (ABET), the need for integrated efforts by Non-Governmental Organizations (NGOS), government departments, schools, and community organizations to improve infrastructure in rural communities, have awareness campaigns on the significance of parental involvement, provision of access to Information Communication Technology (ICT), establishment of homework support groups and quiz clubs, provision of incentives for parental assistance, and reduction of child labour.

- Description: This study on parental involvement in Early Childhood Development in the Bubi district of Zimbabwe investigates parents’ experiences with involvement in the education development of children under six years. Early Childhood Development in Zimbabwe is a community based programme, hence the interest on parents in their involvement in the education and development. To investigate this phenomenon a thorough background of the Bronfenbrenner’s ecological systems theory was employed. The theory is based on the principles of interconnectedness within settings and the linkages between settings that affect individual development. The study focused on the immediate, being the microsystems. The interpretive paradigm and the qualitative approach were employed to explore the parents’ experiences with involvement in the education development of children under six years. Purposive sampling was used to select a small sample of two Heads of schools, four Early Childhood Development teachers and sixteen parents; these were from two schools in the Bubi district of Matabeleland, North Province of Zimbabwe. Obtained results reveal that all the stakeholders involved in the study seem to have limited knowledge of parental involvement. It also emerged that the involvement in the district is biased towards the physical needs of the school only. The results also revealed that there are so many factors that contribute to the non-involvement of parents in their children’s education and development such as poverty, lack of knowledge, culture and attitude, just to mention a few. In view of the findings the study recommends that the Government should provide statutory instruments that clearly state the role of the parents, especially because of the fact that, currently, the programme in the country is community based. The colleges should also empower student teachers during their training on parental involvement.

- Description: Foundation Phase in many schools is dominated by females and there are no or few male teachers in these grades. Foundation Phase comprises both boys and girls and if girls need female teachers to teach them, so the boys also need male teachers. One of the reasons why males do not want to teach in the Foundation Phase is the gender stereotype that Foundation Phase is a woman’s job, which deprive young learners the benefits that they could enjoy by having male teachers in their early years. The objectives of this study were to establish the parents’ perceptions about male teachers’ underrepresentation in the Foundation Phase; to determine how parents and their children can benefit from being taught by male teachers in the FP; to ascertain what challenges parents perceive are experienced by male teachers in the FP and to ascertain how SGB parent component can attract male teachers for FP teaching in their schools. The study was conducted in the East London Education District from three primary schools in urban, semi-urban and rural school settings. The schools selected were those that have male teachers in the FP in Grade R, 1, 2 and 3. A purposeful sample of nine parents who have children in male teacher classes in the Foundation Phase were used; three parents from each school. Qualitative data were generated through semi-structured interviews and observations, using phenomenology design. Thematic analysis was conducted on the basis of the themes that emerged from the participants’ responses to the research questions. This study adopted an interpretive paradigm to get an understanding of parents’ perceptions about male teachers’ underrepresentation in the FP from parents who have children in the male teacher classes in the FP. The findings indicated that parents feel a need for male teachers in the FP to act as disciplinarians. They also noted that their children who are taught by male teachers have good behaviours. Benefits like gender equality, improvement in sports, confidence of learners in doing their work and grooming and balancing for higher levels. It has appeared that parents also understand that male teachers experience challenges of being unaccepted by the parents of learners and also by their female colleagues. These challenges stem from the fact that teaching in FP is associated with being nannies which is a female duty; males are associated with child abuse and are thought to be paedophiles and there a great lack of trust due to these associations pointed at them. Parents in their responses have shown that they are for the view that the SGB parent component should ensure that male teachers are employed in the FP by recommending them (male teachers) in the posts at Foundation Phase level and that it should be adopted in their schools.

- Description: There is a growing body of research on sexual citizenship that focuses attention on gender and which bridges the gap between public and private life in order to rethink citizenship from a feminist perspective. This is in contrast to understandings of citizenship that promote policies of sexual regulation and a heteronormative ideal of citizenship. My research takes the form of a qualitative case study. Using data from two focus group discussions, fifteen personal diaries, as well as social media posts, I analyse participation in the Silent Protest, an annual anti-rape protest, through the lens of sexual citizenship. I look at how participation in the protest promotes or inhibits inclusive and process-based understandings of sexual violence and sexualities issues. Data were analysed using thematic analysis and the results of the analysis are presented into two parts. The first part of the analysis discusses the politics of affect and witnessing as two processes through which allies’ understandings of sexual violence are shaped. The second part of analysis shows that the Silent Protest contributes to people’s knowledge and understandings of sexual violence in relation to sexualities in a range of ways. Examples of inclusive understandings are: (1) insights about rape in relation to gender and heteronormative inequalities, culture and patriarchal dominance; (2) understanding of critical sexual citizenship in relation to sexual violence; and (3) understanding of politics of recognition (the need for recognition of the importance of safe spaces for formal and informal support for victim-survivors and recognition of victim-survivors’ identities). However, some of the understandings are limited to emotion and affect dynamics. In some ways, therefore, the Silent Protest fails to promote understandings significant to inclusive citizenship, including understandings of entitlements to non-discriminatory sexual health care services and legal services.

- Description: This study aimed at assessing the impact of communication on the sustainability of poverty alleviation programmes established for selected beneficiaries in the rural community of Lifajaneng. This is conducted with the purpose of understanding how the Mafeteng community engages in the poverty alleviation projects carried out within their area of residence, so as to encourage more commitment in participation. The conceptual framework for this study is the empowerment approach and the study is informed by two theories; the participatory communication theory and the diffusion of innovation theory. The study employed the mixed method approach to gather and analyze the data; that is using questionnaires, focus group discussions and face to face interviews to solicit for information from project participants and project managers. The quantitative data was presented and analyzed through charts and graphs buttressed with themes that emerged in the qualitative data. The study revealed that the sustainability of the poverty alleviation projects remains questionable due to a number of challenges. The results reflect that communities are more comfortable when the mother language (Sesotho) is used predominantly as the medium of communication. The results also reflected that meetings had a higher attendance rate if called for by local leaders through word of mouth followed by communications done telephonically. Mainstream media such as radio and newspapers were the least effective when mobilizing the communities for meetings related to the poverty alleviation projects in the poor community. The study also unfolded the following issues; lack of full participation and commitment of the beneficiaries, inadequate funding to allow sufficient training of the beneficiaries. This is because the funds had some strings attached and the beneficiaries had their own expectations of the funds, therefore the objectives and the limits of the funder did not match the objectives and the limitations of the beneficiaries. Hence, the end results are lack of motivation for the beneficiaries.
