EMERGING TECHNOLOGIES: COMMERCIAL READINESS INDEX (CRI) FOR MEDICAL ADDITIVE MANUFACTURING (AM)
ArticleTechnology Readiness Level (TRL) is widely used as a measure of technology maturity. However, TRL is not necessarily a good indicator of commercial readiness. In the renewable energy sector a Commercial Readiness Index (CRI) is used where only a technology with a high TRL qualifies for commercial readiness. Similarly TRL is used to measure the maturity of Additive Manufacturing (AM) technologies. This research proposes a Commercial Readiness Index (CRI) for Additive Manufacturing. A case-study on maxillofacial Ti6Al4V implants manufactured with AM is referred to
Work family conflict amongst females in a service organisation in the Western Cape
Magister Commercii - MComIn recent years, there has been a proliferation in research on work-family conflict which has become more prevalent in recent years due to the economic climate in which increasingly large numbers of women are entering or returning to the labour market. Finding equilibrium in work and family arenas has also become more important to South African employees. Traditional gender roles have evolved and the role of females as homemakers is no longer the norm. However, an alternative set of social standards have not yet been established as a substitute to new patterns of work and family life. As a result, it is important to focus on concerns relating to female experiences in the workplace to try and overcome the effects of work-family conflict on females.Job stress and role stress have increased dramatically in work and family life, as more women attempt to balance responsibilities at home whilst simultaneously trying to overcome challenges faced with at the office. Typically role ambiguity, role overload and role interference arises and ultimately produces two forms of conflict: time-based conflict and strain-based conflict. Self-efficacy and implementing coping strategies are means to overcome this.The objective of this study was to explore and add to existing research done on work-family conflict amongst females in the workplace. More specifically the study is to determine whether relationships exist between the variables: job stress, role stress, role overload, inter-role conflict, spousal support, coping behaviours; job, family and life satisfaction, emotional exhaustion; the nature of the relationships and the causal impacts between these variables.Two hundred questionnaires were administered and 150 were returned to women employed in a service oriented organisation in the Western Cape.The statistical package for social sciences (SPSS) was utilized to analyze and present data in this research with frequency tables and graphical illustrations to provide information on key demographic variables in this study. The results reveal that there are statistically significant relationships amongst work overload and work-family conflict (WFC). There was also a significant relationship between parental overload and WFC. Moreover, the strongest relationship emerged between WFC and family-to-work conflict (FWC). Females experiencing WFC showed a tendency to rely on problem-focused coping strategies. In addition, there was an inverse relationship between job satisfaction and WFC.
There was a significant difference in WFC based on age, tenure, number of children, income and tenure. There was no significant difference in WFC on the basis of marital status. There were statistically significant differences in FWC based on some of the biographical characteristics of the respondents. There was a significant difference in FWC based on age, tenure, income and occupation.Approximately 35% of the variance in WFC can be explained by age, education, income, work overload, parental overload and spousal support. These variables account for 33.53% of the variance in WFC, and suggest that other unexplored variables could explain the variance in WFC levels experienced by respondents. Approximately 38% of the variance in role stressors can be attributed to age, education, income, work overload, parental overload and spousal support in relation to FWC. The results which emanated from the current study assist in furthering an understanding of WFC and FWC. Individual and organisational implications are discussed and recommendations are made to further enhance this study with additional research into this area being warranted
“Without a mother”: caregivers and community members’ views about the impacts of maternal mortality on families in KwaZulu-Natal, South Africa.
BACKGROUND: Maternal mortality in South Africa is high and a cause for concern especially because the bulk of deaths from maternal causes are preventable. One of the proposed reasons for persistently high maternal mortality is HIV which causes death both indirectly and directly. While there is some evidence for the impact of maternal death on children and families in South Africa, few studies have explored the impacts of maternal mortality on the well-being of the surviving infants, older children and family. This study provides qualitative insight into the consequences of maternal mortality for child and family well-being throughout the life-course.
METHODS: This qualitative study was conducted in rural and peri-urban communities in Vulindlela, KwaZulu-Natal. The sample included 22 families directly affected by maternal mortality, 15 community stakeholders and 7 community focus group discussions. These provided unique and diverse perspectives about the causes, experiences and impacts of maternal mortality.
RESULTS AND DISCUSSION: Children left behind were primarily cared for by female family members, even where a father was alive and involved. The financial burden for care and children’s basic needs were largely met through government grants (direct and indirectly targeted at children) and/or through an obligation for the father or his family to assist. The repercussions of losing a mother were felt more by older children for whom it was harder for caregivers to provide educational supervision and emotional or psychological support. Respondents expressed concerns about adolescent’s educational attainment, general behaviour and particularly girl’s sexual risk.
CONCLUSION: These results illuminate the high costs to surviving children and their families of failing to reduce maternal mortality in South Africa. Ensuring social protection and community support is important for remaining children and families. Additional qualitative evidence is needed to explore differential effects for children by gender and to guide future research and inform policies and programs aimed at supporting maternal orphans and other vulnerable children throughout their development.Web of Scienc
Client-centred design evolution via functional prototyping
The product design process involves communication of potential design solutions to customers. Fully functional prototypes are most suitable for this because they are readily accepted and allow simultaneous evaluation of all design criteria. However, they are often seen as expensive, time-consuming and not fully representative of the final product material. Therefore, they are usually reserved for customer validation of the final design rather than to keep them involved in every product evolution iteration. This research proposes that rapid prototypes should be used to facilitate a method referred to as Customer Interaction through Functional Prototypes (CIFP). An action research methodology was employed to test the efficacy of applying this method to a real-world product design brief. Customers were able to fully evaluate the aesthetic, ergonomic and functional parameters of the product during every design iteration. This resulted in accelerated product development, sensitivity to the client's needs, a new dimension of 'natural' communication and a successful product design
Why Are Outcomes Different for Registry Patients Enrolled Prospectively and Retrospectively? Insights from the Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF).
Background: Retrospective and prospective observational studies are designed to reflect real-world evidence on clinical practice, but can yield conflicting results. The GARFIELD-AF Registry includes both methods of enrolment and allows analysis of differences in patient characteristics and outcomes that may result. Methods and Results: Patients with atrial fibrillation (AF) and ≥1 risk factor for stroke at diagnosis of AF were recruited either retrospectively (n = 5069) or prospectively (n = 5501) from 19 countries and then followed prospectively. The retrospectively enrolled cohort comprised patients with established AF (for a least 6, and up to 24 months before enrolment), who were identified retrospectively (and baseline and partial follow-up data were collected from the emedical records) and then followed prospectively between 0-18 months (such that the total time of follow-up was 24 months; data collection Dec-2009 and Oct-2010). In the prospectively enrolled cohort, patients with newly diagnosed AF (≤6 weeks after diagnosis) were recruited between Mar-2010 and Oct-2011 and were followed for 24 months after enrolment. Differences between the cohorts were observed in clinical characteristics, including type of AF, stroke prevention strategies, and event rates. More patients in the retrospectively identified cohort received vitamin K antagonists (62.1% vs. 53.2%) and fewer received non-vitamin K oral anticoagulants (1.8% vs . 4.2%). All-cause mortality rates per 100 person-years during the prospective follow-up (starting the first study visit up to 1 year) were significantly lower in the retrospective than prospectively identified cohort (3.04 [95% CI 2.51 to 3.67] vs . 4.05 [95% CI 3.53 to 4.63]; p = 0.016). Conclusions: Interpretations of data from registries that aim to evaluate the characteristics and outcomes of patients with AF must take account of differences in registry design and the impact of recall bias and survivorship bias that is incurred with retrospective enrolment.

When the Remedy is Worse than the Disease: Adjusting Survey Income Data for Price Differentials, with Special Reference to Mozambique
Making cities mental health friendly for adolescents and young adults
Urban life shapes the mental health of city dwellers, and although cities provide access to health, education and economic gain, urban environments are often detrimental to mental health1,2. Increasing urbanization over the next three decades will be accompanied by a growing population of children and adolescents living in cities3. Shaping the aspects of urban life that influence youth mental health could have an enormous impact on adolescent well-being and adult trajectories4. We invited a multidisciplinary, global group of researchers, practitioners, advocates and young people to complete sequential surveys to identify and prioritize the characteristics of a mental health-friendly city for young people. Here we show a set of ranked characteristic statements, grouped by personal, interpersonal, community, organizational, policy and environmental domains of intervention. Life skills for personal development, valuing and accepting young people’s ideas and choices, providing safe public space for social connection, employment and job security, centring youth input in urban planning and design, and addressing adverse social determinants were priorities by domain. We report the adversities that COVID-19 generated and link relevant actions to these data. Our findings highlight the need for intersectoral, multilevel intervention and for inclusive, equitable, participatory design of cities that support youth mental health
Who is accessing public-sector anti-retroviral treatment in the Free State, South Africa? An exploratory study of the first three years of programme implementation
<p>Abstract</p> <p>Background</p> <p>Although South Africa has the largest public-sector anti-retroviral treatment (ART) programme in the world, anti-retroviral coverage in adults was only 40.2% in 2008. However, longitudinal studies of who is accessing the South African public-sector ART programme are scarce. This study therefore had one main research question: who is accessing public-sector ART in the Free State Province, South Africa? The study aimed to extend the current literature by investigating, in a quantitative manner and using a longitudinal study design, the participants enrolled in the public-sector ART programme in the period 2004-2006 in the Free State Province of South Africa.</p> <p>Methods</p> <p>Differences in the demographic (age, sex, population group and marital status) socio-economic (education, income, neo-material indicators), geographic (travel costs, relocation for ART), and medical characteristics (CD4, viral load, time since first diagnosis, treatment status) among 912 patients enrolled in the Free State public-sector ART programme between 2004 and 2006 were assessed with one-way analysis of variance, Bonferroni post-hoc analysis, and cross tabulations with the chi square test.</p> <p>Results</p> <p>The patients accessing treatment tended to be female (71.1%) and unemployed (83.4%). However, although relatively poor, those most likely to access ART services were not the most impoverished patients. The proportion of female patients increased (<it>P </it>< 0.05) and their socio-economic situation improved between 2004 and 2006 (<it>P </it>< 0.05). The increasing mean transport cost (<it>P </it>< 0.05) to visit the facility is worrying, because this cost is an important barrier to ART uptake and adherence. Encouragingly, the study results revealed that the interval between the first HIV-positive diagnosis and ART initiation decreased steadily over time (<it>P </it>< 0.05). This was also reflected in the increasing baseline CD4 cell count at ART initiation (<it>P </it>< 0.05).</p> <p>Conclusions</p> <p>Our analysis showed significant changes in the demographic, socio-economic, geographic, and medical characteristics of the patients during the first three years of the programme. Knowledge of the characteristics of these patients can assist policy makers in developing measures to retain them in care. The information reported here can also be usefully applied to target patient groups that are currently not reached in the implementation of the ART programme.</p
HIV Prevention in High-Risk Women in South Africa: Condom Use and the Need for Change
INTRODUCTION: Young women are at disproportionate risk of HIV infection in South Africa. Understanding risk behaviors and factors associated with ability to negotiate safe sex and condom use is likely to be key in curbing the spread of HIV. Traditionally prevention efforts have focused on creating behavioral changes by increasing knowledge about HIV/AIDS. METHODS: This was a cross-sectional analysis from a prospective observational cohort study of 245 women at a high-risk of HIV infection in KwaZulu-Natal, South Africa. RESULTS: Participants demonstrated a high level of HIV/AIDS knowledge. Overall, 60.3% of participants reported condom use. Reported condom use at last sexual encounter varied slightly by partner type (57.0% with steady versus 64.4% with casual partners), and self-perceived ability to choose to use a condom was significantly lower with steady partners compared to casual partners (p<0.01). In multivariate analysis, women who had high school education were more likely to use condoms at their last sex encounter compared to those with only primary school education (RR of 1.36 (95% Confidence Interval (CI) 1.06-1.75) and 1.46 (95% CI 1.13-1.88) for grades 8-10 and 11-12, respectively). Those who used condoms as a contraceptive method were twice as likely to use condoms compared to women who did not report using them as a contraceptive method. Greater perceived ability to choose to use condoms was associated with higher self-reported condom use at last encounter, irrespective of partner type (RR = 2.65 (95% CI 2.15-32.5). DISCUSSION: Self-perceived ability to use condoms, level of formal education and condom use as a contraceptive were all significantly associated with self-reported condom use at last sexual encounter. These findings suggest that that gender inequality and access to formal education, as opposed to lack of HIV/AIDS knowledge, prevent safer sexual practices in South Africa
Multidimensional Poverty and Child Survival in India
Background: Though the concept of multidimensional poverty has been acknowledged cutting across the disciplines (among economists, public health professionals, development thinkers, social scientists, policy makers and international organizations) and included in the development agenda, its measurement and application are still limited. Objectives and Methodology: Using unit data from the National Family and Health Survey 3, India, this paper measures poverty in multidimensional space and examine the linkages of multidimensional poverty with child survival. The multidimensional poverty is measured in the dimension of knowledge, health and wealth and the child survival is measured with respect to infant mortality and under-five mortality. Descriptive statistics, principal component analyses and the life table methods are used in the analyses. Results: The estimates of multidimensional poverty are robust and the inter-state differentials are large. While infant mortality rate and under-five mortality rate are disproportionately higher among the abject poor compared to the nonpoor, there are no significant differences in child survival among educationally, economically and health poor at the national level. State pattern in child survival among the education, economical and health poor are mixed. Conclusion: Use of multidimensional poverty measures help to identify abject poor who are unlikely to come out of poverty trap. The child survival is significantly lower among abject poor compared to moderate poor and non-poor. We urge t
