  • Description: Context: Despite the multiple differences between athletic events and sports, they all share the sporadic bouts of moderate to extreme intensities and all require some contribution from an integrated bioenergetic system to allow for optimal performance. Although D’ is often considered as an ‘anaerobic work capacity’, such a definition is over-simplistic and its precise composition is nebulous, especially given the mixed findings of the experimental evidence. Clearly, further research is needed to provide a more complete understanding of the D’ parameter, as well as the speed reserve(range of speeds exceeding critical speed) especially within high-intensity exercise. Purpose (Aim): The aim of this study is to determine whether a short term high-intensity speed training intervention within the severe intensity domain effects speed reserve in athletic and non-athletic individuals considered moderately trained.Methods: A quantitative research design was used. Participantscompletedbaseline testing (pre-test), after which they were assigned into two groups. Both groups received a HIIT training program, with group 1 (G140%) receiving a program based on intensity prescription (work bouts performed at 140% of CS)and group 2 (G90-s) receiving a program based on time intervals (work bouts performed for 90-s). HIIT sessions were performed twice-weekly for a total of 6-weeks. A post-test assessment was then conducted by both groups to determine whether any changes have accrued in any of the physiological variables in question. Participants of the study met a specific criterion(18 –30 years of age, residing in Nelson Mandela Bay, and met the minimum fitness requirements). Results: No significant between-group differences were evident prior to and following cessation of the HIIT intervention. Findings that can be highlighted holistically include improvements in CS(G140%: M = 0.62 m.s-1; G90-s: M = 0.46 m.s-1)and 𝑉̇𝑂2𝑚𝑎𝑥 (G140%: +3.81 ml.kg-1.min-1; G90-s: +5.19 ml.kg-1.min-1)and a decrease in fatigue index (G140%: M = -6.75%; G90-s: M = -4.38%) and D’(G140%: M = -56.34 m; G90-s: M = -18.36 m).Normative data were generated for athletic and non-athletic participants using the standard nine (Stanine) categorization to facilitate interpretation and recommendations of key parameters for coaches and clinicians. Moreover, a deterministic model was also generated which revealed novel interactions and the strength of the relationship between variables-potentially opening new and innovative areas of future research. Conclusions: The interval durations and speeds utilised in the present study were insufficient to stimulate an increase in D’. To elicit an increase of D’, one would have to decrease the duration of the intervals performed(i.e. < 90-sec), while increasing speed at which the intervals performed at some speed greater than 140% of CS, but below MSS. Further research is needed to understand the physiological underpinning of the D’ parameter both in isolation and in conjunction with CS. It is clear that D’ is influenced by parameters such as MSS, 𝜏d and FI%; therefore, these sub-parameters should be explored further as potentiators for moderating the D’ parameter.

  • Description: Purpose: Stage 3 of the pharmaceutical process validation lifecycle, is called continued process verification (CPV). CPV is the final stage of lifecycle management and is intended to provide ongoing assurance that during routine production that a process remains in a state of control. Since CPV is a relatively new focus area for regulators, many legacy products will not have undergone Stage 3 process validation. Therefore, an opportunity existed to review the impact and challenges of implementing CPV on a legacy product. Methodology: This study employed quantitative analysis to evaluate the impact of CPV on process stability and end product quality for Product X, a legacy product manufactured at a generics manufacturing facility. Initial Stage 3a CPV was used to review historical process data and identify special cause variation. Corrective and preventative actions were taken to address these statistical outliers and the impact of these process changes were evaluated in Stage 3b. Results: CPV implementation appeared to have an effect on process control, stability and capability for Product X. In Stage 3b, an increase in statistical outliers along with significant changes to process mean and standard deviation were seen for the critical process parameters, average mass and hardness. An improvement in process capability for the critical quality attributes, assay and dissolution, was also seen. Conclusion: The largest benefit of CPV implementation, especially for a legacy product, is the process knowledge gained. This provided opportunities for process improvement and ultimately benefited patient safety.

  • Description: Probation officers, as social workers, play a central role in the child justice system. They are expected to collaborate with various stakeholders within the multi-stakeholder child justice system. They have to meet the various expectations of these stakeholdersthatincludepolice, prosecutors, lawyers and magistrates while ensuring the best interest of the children involved in the child justice system. Despite the important rolethat isplayed by probation officers in the system, there is a gap in literature on the experiences and coping strategies of probation officers in fulfilling their roles within a multi-stakeholder context. This was a qualitative study that was exploratory-descriptive and contextual in design. A non-probability purposive sampling technique was employed to identify probation officers who are working in Vhembe district, Limpopo and who have a minimum of two years working experience as probation officers. Individual semi-structured interviews were conducted with the selected probation officers, and the data collected was analysed using thematic data analysis. The trustworthiness of the research process and the findings was enhanced by employing a variety of data verification strategies. This research contributes to a greater understanding of probation officers’ experiences and coping strategies in fulfilling their role within the multi-stakeholder child justice system. Thestudy revealed that most probation officers experienced difficulties in fulfilling their role within the multi-stakeholder child justice system. They needed resources, supervisors who understand probation services and full support from the department and other child justice stakeholders. The study revealed various coping strategies that probation officers employed in order to cope with fulfilling their role. Probation Officers use personal resources as a coping strategy, draw support from their colleagues andregard job satisfaction as a coping strategy.

  • Description: School is a rich source of information about the world, history, nature and its phenomena. Learning is an important part in young people lives and it begins at school. A young person can learn various subjects and facts in schools that would be life-long remembered. Schools can thus be regarded as an important instrument contributing to the positive development of young people.These young people are born into families and in addition to the school the family is regarded as the basic source of strength, nurturance and support for its individual members as well as ensuring stability and generational continuity. Families also play a key role in the development of young people. However, many families struggle with socio-economic issues like poverty, substance abuse and conflict amongst parents and caregivers. The focus of this study is on factors within the school environment that enhance the resilience of high school learnerswhere their experiences of the family’s less than ideal socio-economic situation and challenges create barriers to learning. Literature shows that the school is a place where learners spend the largest portion of their time per day. When learners leave homeforschool, they become the responsibility of the teacher. Teachers in high schools are thus challenged to facilitatereal support to vast number of learners who facedifficult issues in their personal lives. The researcher was interested to know what these young people regard as the factors in school that enhance their resilience despite difficult family circumstances. This study employed a qualitative research approach, embedded in an explorative anddescriptive research design.The sample of the study was drawn from young people who have successfully completed high school. A non-probability, volunteer sampling technique wasemployed to recruit ten young people. They were interviewed using semi-structured interviews. The research ethics such as voluntary participation, informed consent, confidentiality and principle of no harm to participants were adhered to. To ensure the trustworthiness of the data, the researcher observed aspects of credibility, transferability, dependability and conformability. The findings of the study couldcontribute to local knowledge and an increased understanding of aspects of the school that supportresilience-building for young people from challenging circumstances. Young people interviewed in the study came from backgrounds where they experienced various socio-economic challenges, they were able to reflect on strengths in their family systems, personal strengths and how it influences their choices. They also spoke about the positive role the school played in building their resilience and made valuable contributions about how the school can be responsive to students with varying strength-sets.

  • Description: Rationale: Although there has been active promotion of breastfeeding for the past decades in South Africa, there has been inadequate support from multiple role players. Strategies that do not engage important family members, such as grandmothers in supporting breastfeeding are likely to fail. In many African countries, grandmothers often make critical decisions about early child feeding practices, particularly for first-time mothers. Despite the influence grandmothers have, limited studies have been done in South Africa to assess whether it is possible to change breastfeeding outcomes by empowering grandmothers as well as including them in intervention programmes. Nelson Mandela University, in collaboration with the United Nations Children Education Fund (UNICEF) and a local Non-Governmental Organisation (NGO), recently launched a breastfeeding support programme, Sakha Esethu. The aim was to capacitate both primary and secondary caregivers to enable them to provide optimal breastfeeding support for mothers in various communities. However, it was important to explore the perceptions of grandmothers regarding breastfeeding to assess whether improved breastfeeding knowledge will translate into changed perceptions and therefore improved support for exclusive breastfeeding in communities in Nelson Mandela Bay. Aim: The study aimed to describe and explore the perceptions of grandmothers regarding breastfeeding after participating in a breastfeeding support programme in Nelson Mandela Bay health district (NMBHD). Methodology: The study followed a descriptive-exploratory, contextual study design with a qualitative approach. The four ethical principles that guided the study were: autonomy, non-maleficence, beneficence and justice. The researcher conducted five focus group discussions (FGD) at ECD centres in NMBHD, where 34 grandmothers participated in the study. Participants were chosen using a purposively sampling technique and data was collected using FGD interviews. Verbatim transcription was done after every FGD and data was analysed using the eight steps of Tesch’s analysis technique. An independent coder with experience in qualitative data analysis assisted to verify the codes generated. vi Results: Four major themes and eleven subthemes emerged through data analysis. The identified themes were: (1)Participant knowledge regarding breastfeeding. Participants reflected on poor knowledge on the perceived maternal benefits of breastfeeding, variance on the optimal duration of breastfeeding and recognised myths and cultural taboos related to breastfeeding, such as the use of traditional mixes, “dirty” breastmilk and perceived milk insufficiency; (2) Views on complementary feeding. The subthemes that emerged included: Participants shared their views on the age of introduction for complementary foods and feeding practices for infants; (3) Challenges related to breastfeeding. The challenges identified included: challenges for working mothers and those attending school, lack of family support and societal support for EBF, lack of support from healthcare professionals relating to initiation and continuation of breastfeeding and difficulties coping with breast health. (4) Participants enthused about the impact of being supported to optimise breastfeeding.Participants were able to share on the camaraderie benefits experienced from the Sakha Esethu group as well as on the support grandmothers can provide. Conclusion and Recommendations: This study confirmed that participation of grandmothers in the Sakha Esethu programme had an impact on changes in grandmothers’ perceptions regarding breastfeeding. However, the programme can be further improved by placing more emphasis on aspects i.e. maternal benefits of breastfeeding, during mentor training. Furthermore, there is a need to strengthen healthcare worker support and training, especially with regards to adapting counselling strategies to include breastfeeding challenges and cultural beliefs.

  • Description: The primary aim of this study was to compare the effect of a standardised versus customised high-intensity interval training programmeon performance indicators of endurance trained male cyclists utilising a standardised method of prescribing intervals in comparison to a customised method of prescribing intervals based on training feedback. The study was exploratory and quasi-experimental in nature and utilized a quantitative approach. A quasi-experimental, pretest-postestcontrol group study design was used. A total number of 22 participants that met the inclusion criteria were included in the study by means of purposive sampling. The participants were subdivided into an experimental group (n=11) and a control group (n=11)by means of random stratification in order to ensure performance equality between the two groups. The experimental group completed a High-Intensity Interval Training (HIIT) block of 28 days (four weeks) with three weeks of interval-based sessions and one recovery week ending off the block. The programmeutilised the same “anaerobic” type intervals (10 x 30 seconds at 170% PPO with 4 minutes 30 seconds recovery) as the control group, performed twice per week for three consecutive weeks. The Lamberts and Lambert submaximal cycling test (LSCT) was used to determine whether a participant in the experimental group could start his HIIT session on a particular day.Participants were notallowed to start their HIIT session if twoor more of the set criteria weremet.If the participants did not qualify to participate in a HIIT session they were required to perform a low intensity training session in the same venue. Differences between the pre-and post-test showed statistically non-significant improvements (p>0.05) from pre-to post-test for both the experimental and control groups in respect of the physiological variables measured (gas exchange threshold, respiratory compensation point, maximal oxygen consumption). The experimental group did however show more positive, but statistically non-significantimprovements in peak power output. The findings of this study therefore showed that no significant within group nor between group improvements were achieved utilizing a standised versus customised HIIT training programme over the four-week study period. The findings do however suggest that the LSCT may have merit in prescribing HIIT sessions in trained athletesas suggested by the improvements of the experimental group’s peak power output.

  • Description: The primary aim of this study was to compare the Index of Coordination (IdC) for both sprint and endurance swimming and running of less-skilled level triathletes. The researchutilised a quantitative approach, specifically exploratory, with a one group post-test-only research design. Twenty participants from the triathlon community, ages 18 years and older, were selected via purposive and convenient sampling. The participants were expected to complete a total of four physical tests, namely 50 m sprint swim, 1500 m endurance swim, 50 m sprint run,and 5000 m endurance run, on four separate days, over a period of two weeks. The data was collected by video recording each participant performing each of the four different tests andcoded frame-by-frame onDartfish Video Solution (10.0).The IdCwas derived by identifying the time-in markers and time-out markers for both left and right arms when swimming; and by identifying the time-on markers and time-off markers for both left and right legs when running. The results revealed significant differencesbetweenthe IdCvalues ofsprint swimming and endurance swimming(p<0.001); sprint running andendurance running(p<0.001); sprint swimming andsprint running(p<0.001); andendurance swimmingandendurance running(p<0.001).The top performersin each testwere significantly faster than bottom performers(sprint swimming: p<0.001; sprint running:p<0.001; endurance swimming: p<0.001; endurance running: p<0.001) but no significant group differences on associated IdC were found(sprint swimming: p=0.535; sprint running: p=0.857; endurance swimming: p=0.132; endurance running: p=0.775).Bothendurance tests were divided into three equal portions and it was found that 23% ofthe fastest trial endurance swim time can be explained by the IdC obtained in portion three(p=0.032); and that 62% of the fastest trial endurance run time can be explained by the IdC obtained in portion one(p<0.001). The overall findings of the study suggest that an IdC mode is considered efficient relative to the environmental contextand thatIdCis relative to skill level or alternatively independent of performance times. The IdC, therefore, remains inconclusive as an alternative method but warrants further investigation particularly in longer distance endurance events.

  • Description: In elite fastball sports, such as cricket, performance occurs at the limit of human capability as the time constraints of perceiving and acting are severe. Cricket batsmen are therefore required to use the two sources of advanced information (kinematic cues and situational probability) to anticipate an upcoming delivery to negate the effects of the time constraints. The source of information that will be focused on in this study will be situational probability, with the aim being to determine the interaction between bowling sequence and field placement as sources of situational probability used by skilled cricket batsmen to predict a bowler’s intention. Four different conditions were created according to the situational probability information presented to the batsmen, namely no sources, sequence alone, field placement alone, and both sources. Fifteen skilled cricket batsmen were required to face deliveries projected by a bowling machine and make predictions as to where the next delivery outcome was going to pitch based on perceived situational probability information and attempt to make successful bat-ball contact. In order to compare the use and importance of the four conditions of situational probability information,prediction accuracy, response accuracy and the initial movement time of the batsmen were recorded and analysed. Results of the study revealed no significant difference between conditions of situational probability presented to batsmen for prediction accuracy, response accuracy, and initial movement time. However, significant differences were found between categories of congruence for prediction accuracy results. The prediction accuracy results reveal that batsmen equally value each source of situational probability information and that when sources were presented in conjunction with each other, no enhancement in anticipatory performance or interception of the cricket ball occurred.The results of the current study suggest that it is not necessarily the number of sources present, but rather the relevance of the source that is most important for a batsman to predict the outcome of a delivery. The prediction accuracy of batsmen is dependent on the nature of the information presented rather than the amount of information presented. Performers draw upon more pertinent information variables according to the relevance to the task at hand.The response accuracy results reveal that the batsmen have the required action capabilities to make successful bat-ball contact regardless of whether or not they correctly anticipate the upcoming delivery’s landing position.

  • Description: The ability to anticipate the bowler’s intention is vital in skilled cricket batting. Two perceptual-cognitive skills used for anticipation include use of kinematic information and the use of situational probability information. This study aims to investigate the interaction between two sources of situational probability (action preferences of bowlers and opposition field placement) used by skilled cricket batsmen to anticipate the bowler’s intention in an in-situ setting. Fifteen skilled cricket batsmen were required to predict the delivery outcome (landing position) of 72 deliveries bowled by a bowling machine before attempting to strike each delivery. These deliveries were divided into four conditions of situational probability: no sources (control trials); field placement alone; action preference alone; and both field placement and action preferences. Data were collected according to batsmen’s prediction accuracy, response accuracy, and initial movement time. In the presence of situational probability information, batsmen were able to predict delivery outcome significantly better than chance level (25%) and control trials. Results revealed significant differences between sources of situational probability in terms of batsmen’s prediction accuracy but not response accuracy or initial movement time. In cricket batting, it appears that some sources of situational probability information are more valuable than others.

  • Description: In the twenty-first century the internet has become a pervasive part of individuals’ lives and their relationships, changing the way individuals connect, develop and maintain their romantic relationships. The way in which couples use the internet can have a significant impact on their relationship satisfaction, which is often a predictor of the length and success of their relationship. Although the internet is valued for many features, the nature of the internet creates the risk for some individuals to become addicted to the medium which is associated with psychological and relational difficulties. The present study aimed to explore the impact of problematic internet use on individuals’ satisfaction with their offline intimate relationships. A quantitative, non-experimental, cross-sectional, research design was utilised, where participants from Nelson Mandela University completed an online survey (N=388). A non-probability, purposive sampling method was employed with an inclusion criteria which required participants to have daily internet access and to be in a committed romantic relationship. The study analysed four primary variables, namely, online preoccupation, adverse effects of online behaviour, social interactions and general relationship satisfaction. The results of the study were discussed through the lens of the Couple and Family Technology (CFT) framework to explain the processes that underlie the relationship between these variables and indicated that problematic internet use and relationship satisfaction is negatively related. The present study contributes to the body of literature and offers indications for future, in-depth research studies within the field of cyberpsychology.

  • Description: Background: The global, exponential growth in the elderly population and increased longevity has been well documented. South Africa has the highest proportion of older population in sub-Saharan Africa. Empirical research is lacking on the efficacy of exercise interventions for the elderly to prevent fall risk and increase independent living associated with quality of life. Maintenance of muscular strength of the lower body is important to compensate for various physiological deficits due to the ageing process. Aim: The aim of the study was to determine the effects of an eight-week lower extremity strength training intervention on balance and postural control in female elderly, aged 65 years and older, living in a high socio-economic, urban, residential area in Nelson Mandela Bay in the Eastern Cape region of South Africa. Design and Methods: A true-experimental, pre-test, post-test study design, was used with a comparative experimental and control group. A total number of 21 participants met the inclusion criteria and were randomly assigned to an experimental or control group. The experimental group participated in an eight-week strength training intervention, attending exercise sessions, twice a week. Peak isometric strength of the knee flexors/extensors, adductors/abductors of the hip, and plantar / dorsi-flexors of the ankle were assessed post-intervention, using the FET2 handheld dynamometer. Balance was assessed by means the displacement of centre of pressure during the limits of stability and the ellipse area for postural sway assessment on a Kistler force plate, post-intervention. Medial/lateral displacement of centre of pressure and the mean velocity while descending a self-designed, two-step stair case, were determined after the intervention by measures obtained from a Kistler force plate. Descriptive statistics were calculated for measures of central tendency including means standard deviations. T-scores were used to standardise results obtained. Non-parametric, inferential statistics were used to determine the statistical significance of the results. The Wilcoxon matched pairs test and the Mann-Whitney U tests determined the significance of within group comparisons. Statistical significance was set at p<0.05. Spearman rank order correlations were used to measure the strength of associations Results: Lower extremity isometric strength in musculature around the hip, knee and ankle joints, as well as postural sway in a stationary position with eyes opened, have improved significantly after an eight-week resistance training Programme. Improvements in balance has been indicated by limits of stability in the postural sway stance with eyes closed, and dynamic balance during stair descending, were both not significant. Conclusion: The importance of physical interventions to enable the elderly in living a healthy and independent lifestyle should be promoted in all settings. Muscle strength gains and postural sway improvements could have been attributed to neural adaptation and calls for further investigation into the efficacy of strength training over longer durations. The relevance of incorporating stair negotiation as a functional activity of daily living should potentially be included in exercise Programmeprescription by biokineticists, as insufficient control of dynamic balance has been reported to increase fall risk.

  • Description: Non-communicable diseases have become a major cause of mortality, resulting in 55% of deaths in South Africa in 2015. Educators seem to be a high-risk population with high rates of obesity and hypertension. This study, a quantitative descriptive study, was completed with primary school educators in Nelson Mandela Bayas the study population, with the aim of better understanding their knowledge, perceptions and practices with regard to a healthy lifestyle in order to manage and improve their staff wellness, and investigates these areas separately as objectives. A focus was placed on salt and sugar intake in light of recent legislation and taxation on these items in South Africa. The study has three components, namely; anthropometry, a dietary intake assessment via 24-hour dietary recalls and a behavioural questionnaire. Ethics was considered by ensuring the anonymity of participants, using participant numbers and ensuring the written consent of all participants before the commencement of the study. Data collection took place over a period of three days. Educators showed high levels of obesity, with 45,7%(n=21)being categorised as obese class three. Twenty-five percent of the participants reported to have been diagnosed with hypertension. Participants fared well with questions that referred to more general knowledge of nutrition and aspects of staff wellness that was looked at showed that 47,7 % described their job performance as ‘good’, while also noting that 20,5þlt that everything was an effort most of the time. Recommendations include the benefit of an Employee Wellness Programme in order to educate and encourage teachers around different aspects of their health and wellness. Intrinsic motivation is necessary and drastic changes need to be made in order to improve the dire situation in this population of the country.

  • Description: The focus of this study is on mothers, motherhood and the Babies in Mind programme as an early intervention strategy for mothers in South Africa. The rate of maternal mental ill health in our country is alarming. Research consistently confirms that maternal mental health directly affects infant and child mental health. One of the major determinants of mental health is mother-infant attachment. Studies have indicated the range of deleterious effects that maternal mental ill-health and mother-infant attachment issues have on offspring from infancy to adulthood. This has implications for the mental health of future generations and society at large. Researchers have called for evidence-based interventions that address maternal mental health and mother-infant attachment, especially in developing countries. South Africa has no national prevention or treatment programme to address these needs. This study investigated the Babies in Mind programme as an early intervention option to address the gap in promoting maternal mental health and mother-infant attachment. A social constructionist, narrative study was employed to meet the objectives of the study. The aim was to explore mothers’ perceptions of the impact of the Babies in Mind programme, with particular reference to their mental health and their relationships to their infants. Focus was placed on understanding the social constructions of motherhood at the community level and how these constructions were reconstructed through the programme. Purposive sampling was employed and focus groups were conducted to collect the relevant data. The data was analysed using thematic analysis. The findings indicated that mothers’ experiences of the Babies in Mind programme were positive and there were improvements in their mental health and relationships to their infants. A relationship model for mothers was developed based on the themes that emerged from the data analysis.

  • Description: Many research studies propose that we have an ageing population with an increased number of people living past the age of 85 years. Ageing is accompanied by a gradual decline in physical, mental and sensory abilities. Older people may have experienced trauma throughout their lives, and very often, their symptoms of trauma are regarded as part of the ageing process rather than actual symptoms of trauma. In addition, older people often do not seek help throughout their lives for various reasons. While there is research available about older people and trauma, little is known about Eye Movement Integration(EMI)therapy as a treatment intervention in treating symptoms of trauma in older persons. The purpose of this research was an explorative and descriptive study of older people’s responses to EMI therapy as a treatment intervention for their symptoms of trauma. More specifically, the study was designed to determine how older people process their symptoms through EMI therapy and whether they view it as valuable. This qualitative study used an exploratory-descriptive research design with a non-probability, purposive sampling method. The EMI therapy sessions were offered to older adults in the Knysna area who presented with symptoms of trauma. From this group, only those who were able and willing to engage in therapeutic interviews formed part of the research. As part of the study, they consented to the use of their inventories from the EMI sessions as a qualitative document analysis and taking part in qualitative interviews to explore their views on the usefulness of EMI therapy to deal with their trauma. The findings emphasise that older people are not familiar with EMI. However, they view their experience of it in a positive light and regard it as a useful treatment intervention for treating their symptoms. Moreover, EMI seems to be a brief and cost-effective trauma intervention with practical benefits for older adults. The results from this study can assist social work professionals, specifically those working with older people, to address and improve the overall health and emotional wellbeing of older people. Data verification methods ensured the validity of this study

  • Description: Rationale: Lunchboxes that parents prepare for preschool children have been noted to fall short of the recommended paediatrics dietary standards. No research has been done in Nelson Mandela Bay (NMB) to describe the perceptions of parents preparing the lunch boxes, particularly in underprivileged communities, and if nutrition education strategies can improve these practices. This study answered the following research question: How can nutrition education programmes play a role in parents’ perceptions about the content of the lunchboxes of children attending early childhood development centres (ECD) in underprivileged communities of NMB metropole? Aim: The research aimed at describing and exploring parents’ perceptions of the content of pre-school children’s lunch boxes following a nutrition programme.Methods: This descriptive, explorative study adopted a qualitative approach. Twenty-five participants were selected conveniently while five pre-schools were purposively sampled. Following the nutrition programme, data was collected through five Focus Group (FG) discussions and five interviews and was thematically analysed. The ethical principles that guided the study included justice, beneficence and autonomy. Results and Discussion: Five major themes and seventeen sub-themes emerged (1) Participants described the typical foodstuff in children’s lunch boxes which included both high quality and lower-quality foods and fluids; (2) Participants provided views (such as food preferences) on lunch box choices; (3) Principals appraised lunch box rules and the significance of revised rules to improve the lunch boxes;(4) Challenges such as poverty limited healthy food choices; (5) Participants commented on initiatives noted following the nutrition training; for instance, some schools commenced the cultivation of vegetable gardens. Conclusion and Recommendations: The study highlights that specific parent programmes helped to improve healthy lunch box choices in the study population. There is a need for parent programmes tailored to fathers. Dieticians and nutritionists in NMB can train practitioners as change agents in their respective schools.

  • Description: Occupational noise-induced hearing loss (NIHL) develops as a result of continuous excessive noise-exposure levels above 85 dB(A) occupational exposure limit (OEL), over an average period of eight hours per day. Many employees incur hearing loss during a period of five to ten years of employment. Noise-induced hearing loss can be prevented and even be eliminated if the exposed employees adhere to the proper and consistent use of hearing protection devices (HPDs). However, non-compliance makes it impossible to eliminate NIHL. The purpose of the study was to explore and describe the perceptions of employees working in an automotive manufacturing company with regard to the use of HPDs and to make recommendations to the company’s management in relation to the findings of the study. A qualitative, explorative, descriptive and contextual design was used to conduct this study. The research sample comprised all employees working in noise-zone areas above 85 dB(A). Purposive sampling was used to select the research sample. The data were collected by using in-depth interviews. The data analysis was conducted by using Tesch’s method of data analysis. A pilot study was conducted before the main study. Ethical considerations were adhered to throughout the study. The main findings revealed that the participants at the automotive manufacturing company were knowledgeable about the use of different types of HPDs that are used in their work environment even though some participants do not use it all the time. Most employees were aware of the hazardous noise levels emitted by hydraulic presses in their areas, however, some employees become accustomed to the level of noise and ignore using HPDs. Some employees reported use of their preferred types of HPDs. However, issues like comfort design and work-related communications were factors influencing the use of HPDs. In conclusion, it is evident that the people were knowledgeable about the types of hearing protection devices that are used in their areas and the reasons for them. However, the study findings revealed that the employees are not directly involved in selecting the type of HPDs with which they are comfortable. This could have a negative effect on the employees’ morale and their compliance with the use of HPDs. Based on the research findings, the recommendations were made, according to training and future research.

  • Description: Sexual and reproductive health education in South Africa appears to be failing young people as evidenced by the numbers of unplanned pregnancies and sexually transmitted diseases resulting from poor sexual health decision making. High-risk behaviours amongst youth are likely to be a product of the interplay of multiple risk factors on individual and interpersonal levels. The Auntie Stella: Teenagers Talk about Sex, Life and Relationships, is a sexual and reproductive health education toolkit with developmentally timed interventions for sexual and reproductive health education for adolescents. This tool kit has been successfully utilized in such countries as Zimbabwe, Tanzania, Malawi, Mozambique and Zambia. The study aimed to establish if the University health care professionals, including HIV counsellors and nurses, perceive Auntie Stellato be a useful sexual health and reproduction education programme to generate knowledge and prompt and promote safer sexual behaviour. An exploratory descriptive qualitative research design was be utilized, and purposive sampling was employed. Data was collected via focus groups where the toolkit was administered and discussed. Six focus groups were conducted with 12 participants from the Nelson Mandela University’s Campus Health Clinics. The data obtained was analyzed using Braun and Clarke’s (2006) six-step method of thematic analysis. The findings of this study revealed that the Nelson Mandela University health care professionals perceived the Auntie Stellatoolkit as being useful and applicable to the university context in terms of relatability. They expressed thatthe programme is ideally youth-friendly and appropriate for university students. The findings of this small study may have important implications for future research of implementation of sexual and reproductive health education programmes in Higher Education Institutions.

  • Description: Pharmacy graduates in South Africa are expected to undertake a compulsory one-yearinternship in diversepharmacy settings. These settings includethe industrial pharmacy sector,where they are expected to integrate furtherthe knowledge and skills they have acquired during their undergraduate training before entering into the pharmacy profession. The success of graduatesduring the internship,therefore, depends amongst other thingson their perceptions of preparedness. However, the perceptions of South African pharmacy graduates preparedness for the industrial pharmacy settingis not reportedin light of the shift in global pharmacy education from product-based to patient-based education which thus provided the impetus for this study.Semi-structured interviews with individual pharmacy graduateswere utilised to explorethe perceptions of the preparedness regarding the technical and generic skills required of an industrial pharmacy intern. Inductive data analysisculminated in thedevelopment of themes and subthemes. A lack of preparedness as perceived by graduateswas a result of a lack of industrial pharmacy experientialwork-basedpractical training and patient-focused education. Graduates perceived themselves to be fairly prepared with communication and teamwork skills; however, their problem-solving skills werenot clear due tothe scope of work ofanintern pharmacist which hinders them from solvingproblems.Though graduates expressed that they had acquired adequate theoretical training, the lack of practical application resulted in inadequate technical skills preparedness. Graduatespreparedness for the industrial pharmacy can be improved by work-based placements of students in the industry pharmacy setting which will assist students to integrate theory with practice.

  • Description: Traumatic Stress Disorder (PTSD). While the literature provides detailed and comprehensive approaches and counselling modalities to working with clients who experience traumatic events, there is not much evidence on the experiences of individuals who reside in high crime communities. It follows, that the psychological and emotional experiences, as well as needs of such individuals may present with specific requirements from the therapeutic alliance. This study aimed to explore the psychological and emotional effects of repeated exposure to high crime and violence and the implications this posed to traumatic experiences. The study further aimed to develop a set of guidelines that can be drawn upon when working therapeutically with clients who reside in high crime communities. The study draws on a qualitative methodology and 17 participants were interviewed. The transcripts were analysed using thematic analysis and five themes were identified, relevant to the aims and objectives that were set. The findings suggest that the psychological and emotional experiences of individuals who reside in high crime communities, is experienced at a more heightened and prolonged period, thus making the psychotherapeutic intervention employed, more specific. To this effect, the guidelines developed provide specific strategies and approaches thatwere developed based on the themes identified and verified by a panel of psychological experts. The study contributes to the field of trauma, counselling and violence, in that it focuses on an area of trauma that has not been adequately focused on withinthe South African context, as well as in global contexts.
