- Description: Employees in any industry need to continuously update their skills in order to be knowledgeable and competitive. Conducting a needs assessment plays an instrumental role in ensuring that continuous professional development (CPD) training is relevant to the target audience. In many organisations, however, CPD training programmes are often planned and delivered without a comprehensive needs assessment first being undertaken. This was a quantitative study that used a descriptive survey design and an online survey tool for data collection and analysis. Using an all-inclusive sample, the purpose of this study was to explore and describe CPD needs of medical sales representatives at an international medical devices company that operates in South Africa. Descriptive and inferential statistics were used to analyse the data. Research findings are depicted in frequencies, percentages, tables and figures. The findings of the study reveal specific training needs of the respondents and the shortcomings of the existing CPD offerings. The findings show that the CPD training offered by the company under study is mostly product specific and about sales. The respondents have highlighted that they would like to see more practical training to be incorporated into the CPD training programmes. It was also noted that the respondents would like to provide more input into the training programmes that are being offered by the company under study. The study has also identified areas where the company can improve in order to make these CPD training opportunities a more satisfying, educational and developmental experience for the employees. While the study focuses on one company, findings are relevant for other similar companies, as well as companies in other industries, since CPD at the workplace is a necessity in any competitive business environment or industry in order to increase productivity, sales, staff retention and customer satisfaction.

- Description: Midwives are part of the multidisciplinary team in maternal units and have the bulk of the obstetrical and midwifery responsibilities. The responsibilities being referred to include provision of perinatal care and support to grieving women who have lost their babies at birth and to their families. The care referred to in this study is focused mainly on the grieving women and not on the midwife. By virtue of midwives being present in the event of perinatal loss or caring for a woman who experienced perinatal loss, midwives are compelled to be involved and are bound to experience deep emotions. Furthermore, there is little formal support available for midwives caring for women with perinatal loss in Nelson Mandela Bay Health District (NMBHD) and South Africa at large. The purpose of this study was to obtain a deeper understanding of coping and support needs of midwives caring for women with perinatal loss in the NMBHD. The objectives developed for this study were: explore and describe the facilitating conditions that will enable midwives to care for women with perinatal loss in the in NMBHD; explore and describe the inhibitory conditions that prevent midwives from caring for women with perinatal loss in the NMBHD; identify and describe support needs for midwives caring for women with perinatal loss in the NMBHD and develop coping and support recommendations for midwives caring for women with perinatal loss in the NMBHD. After permission had been granted by the Nelson Mandela university and approval from other relevant authorities had been received data collection was conducted between November 2018 and January 2019, using qualitative research design and interviews. The research population included all midwives working in Midwife Obstetric units (MOUs) and referral hospitals in NMBHD. Purposive sampling was used, and the data collection method was semi-structured and audio-taped in one-on-one interviews with midwives. Sample size was determined by data saturation. The number of participants was thirteen and two of these participants formed part of the pilot study. The collected data was analysed using the seven steps of Framework Analysis from which three themes emerged namely: Midwives rely on their own coping mechanisms vi to deal with perinatal loss; Midwives expressed how management influenced the way they coped with perinatal loss events; Midwives expressed the need for psychological and emotional support. Trustworthiness was maintained by observing Lincoln and Guba’s principles of credibility, transferability, dependability and confirmability. The researcher ensured that the Belmont Report ethical principles were maintained throughout the study. Three main coping and support recommendations for midwives caring for women with perinatal loss in the NMBHD were developed using an adapted version of the AGREE II Tool. The recommendations were: Recommendation 1: Facilitate various forms of peer assistance to prepare and support midwives caring for women with perinatal loss; Recommendation 2: Provide formal support systems in the labour unit to assist midwives to care for women with perinatal loss; and Recommendation 3: Strengthen existing EAPs and provide unit-based psychological and emotional support in order to accommodate the needs of midwives caring for women with perinatal loss.

There havebeen few studies done on the coping mechanisms of unemployed Registered Counsellors in the South African context. This field of study is particularly important as Registered Counsellors are the primarymentalhealth care professionals;therefore,their role in psychology is of utmost importance. This study focused on exploring the coping mechanisms of unemployed Registered Counsellors. A qualitative research approach was followed in order to gaina comprehensive understanding regardingthe perceived coping strategies. A combination of purposive,non-probability and snowball sampling techniques was employedto select participants and semi-structured interviews were conducted with them to explore and describe their coping mechanisms. Lazarus and Folkman’stheorywas utilised to provide a theoretical understanding of the coping mechanisms. Unemployment is perceived to cause stress and may lead to maladaptive coping strategies. It was perceived to have an impact on the professional’s goalsand increased financial strain in their lives. However, communication, social and family support, positive attitudes, availability to opportunities and advocacy for the profession were identified as effective coping mechanisms. The majority of the participants perceived good communication about the situation and supportive relationships to be the most effective strategies to be utilised in their lives.

- Description: Trauma exposure and PTSD are widespread health concerns in South Africa. This country is also extremely culturally diverse. The effects of cultural position on PTSD development are unknown. The objective was to explore these possibilities in detail. Individuals eighteen years or older with a stable pre-existing PTSD diagnosis participated in semi-structured voice recorded interviews. Both participants displayed clear conscious changes in cultural position following trauma exposure, some of which are believed to be due to a failure of support and acknowledgement from their collective. This would have contributed to PTSD development. Main themes identified were reactions of others and a paradigm shift. Further, more detailed research is required in this field.

- Description: Context: Swimming is a highly competitive sport, with elite swimmers and coaches constantly looking for ways to improve and challenge themselves to meet new performance goals. The implementation of technology in swimming has proven to be a vital tool in athlete monitoring and in providing coaches with additional information on the swimmer’s performance. Example of this technology is the use of inertial sensory devices such as tri-axial accelerometers. The accelerometers can be used to provide kinematic information with regards to the swimmer’s stroke rate, stroke length and stroke mechanics. In a typical training session, coaches would have to manually time and count their swimmer’s strokes to be able to gain the kinematic information they require. Hence, the use ofinertial sensory technology, such as accelerometers, would provide the necessary information coaches require, allowing them to concentrate on other performance aspects such as theirswimmer’s technique.Aim and objectives: The aim of this study was to determine the kinematic parameters and swimming stroke mechanics that could be derived from tri-axial accelerometers, during a 200-m individual medley (IM) event in South African national level swimmers. Three objectives were set to meet the aim of the study. The first was to identify and differentiate each of the stroking styles using tri-axial accelerometers. The second was to identify and differentiate the kinematic parametersand stroke mechanicsfor all four strokes using tri-axial accelerometers. The third objective was to implement machine learning to automate the identification and interpretation of the accelerometer data. Method:A quantitative, non-experimental descriptive one group post-test only design was used, in which 15 national level swimmers, of which seven male and eight female (mean ±SD: age: 20.9 ± 2.90 years; height: 173.28 ± 10.61 cm; weight: 67.81 ± 8.09 kg; arm span: 178.21 ± 12.15 cm) were tested. Three anthropometric measures were taken (height, weight and arm span) prior to testing, with two tri-axial accelerometers and Polar V800watch and heart rate belt attached to the swimmers left wrist, upper-back and chest, respectively. All swimmerswere required to perform three main swimming sets: 50-m IM, 100-m variation and 200-mIM. Variousdescriptivestatisticsincluding mean, standard deviation and confidence intervals (95%)were used to describe the data. with further inferential statistics including paired t-test, intra-class correlation and Bland Altman analysis wereused to describe the relationship ivbetween the accelerometer and the manually estimated parameters. Additionally, arepeated measures one-way ANOVA (with post-hoc Tukey HSD test) werealso used in an inter-comparison of the stroke parameters between each of the stroking styles. A confusion matrix wasused to measure the classification accuracy of the machine learning model implemented on the accelerometer data.Results:The accelerometers proved successful in identifyingand discerningthe stroke mechanics for each of the four stroking styles, with the use of video footage to validatethe findings. In the stroke kinematic differentiation, theBland Altman analysisresultsshowed an agreement between themanual method and accelerometer-derived estimates, although a discrepancy was evident for several of the kinematic parameters, with a significant difference found with the estimated lap time, average swimming velocity and stroke rate (paired t-test: p <0.001 for all swim sets). The inter-comparison between the stroke parameters per stroking style showed a significant difference with average swimming velocity (repeated one-way ANOVA: F = 1789.37, p <0.001), averages stroke rate (repeated one-way ANOVA: F = 671.70, p <0.001) and average stroke length (repeated one-way ANOVA: F = 346.46, p<0.001) for the population group tested. Furtheranalysis with post-hoc Tukey HSD test showed no significant difference wereevident for the average swimming velocity(Tukey: p > 0.05for all strokes)andbetween freestyle and backstroke for the average stroke rate and stroke length (Tukey:p = 0.0968 andp = 0.997, respectively).Lastly, the machine learning model found a classification accuracy of 96.6% in identifyingand labelling the stroking styles fromthe accelerometer data.Conclusion: It was shown that the tri-axial accelerometers were successful in the identification and differentiation of all the stroking styles, stroke mechanics and kinematics, although a discrepancy was found with the average swimming velocity, stroke rate and lap time estimations. The machine learning model implemented proved the benefits of using artificial intelligence to ease the data process and interpretation by automatically labelling the accelerometer data. Therefore, the use of tri-axial accelerometers as a coaching aid has major potential in the swimming community. However, further research is required to eliminate the time-consuming data processingand to increasetheaccuracy of the accelerometer in the measurement of all the stroke kinematics.

- 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: 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: 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.

- 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. A platform for continued support and discussion was organised via a social media (Whatsapp) support group. Twelve 7guidelines were suggested for the implementation of intervention programmes such as the Babies in Mind programme at the community level.

- 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
