The economy-wide impacts of the labour intensification of infrastructure expenditure in South Africa

This paper examines the performance of public works in addressing both micro and macroeconomic policy objectives relating to growth, employment and poverty reduction in South Africa. The microeconomic analysis suggests that while participation in a public works programme may contribute to a reduction in the depth of poverty, with improvements in participation in education and nutrition, and have positive psychosocial benefits, the impact of a short-term programme may not be significant in terms of a reduction in headcount poverty or improvements in asset ownership (material or financial). In this case the public works programme income may function essentially as a temporary wage shock, since the insurance function of the transfer is limited by the short duration of the employment period. From a macroeconomic perspective, a social accounting matrix (SAM) is used to estimate the impact of shifting R3 billion expenditure from machine to labour based infrastructure provision over a one year period. The SAM indicates that the impact would be to increase employment by 1%, the income of the poorest quintile by 2% (if employment were exclusively targeted to this group) and GDP by 0.1%. While these are positive outcomes, they are not significant in terms of South Africa's overall economic and employment performance. The conclusion is drawn that from both a macro and microeconomic perspective, there is reason to be cautious about the potential of a national public works programme based on shifting the labour intensity of infrastructure provision, and offering short-term employment opportunities, to have a significant impact on poverty, employment or growth.

The Perceptions about ASD’s Rising Rates: A Comparison between the General Public and ASD Professionals.

The research conducted for this project answered the question: what are the public’s perceptions about ASD and its rising rates and how do these compare to the perceptions of professionals providing services to children with ASD? The participants of this research study were both male and female of a non-specific age group that work with children diagnosed with ASD, and those who have no contact with children diagnosed with ASD. 49.5% of survey respondents were professionals that have contact with students with ASD and 50.5% of respondents were those who have no contact with children diagnosed with ASD.The majority of both professionals and the general public believed that it is because of more awareness, knowledge, research, and early intervention, which aligns with what I found in my research. There isn’t necessarily a growing number of people with ASD, but there is a growing number of diagnoses because we can now better identify it. 17% of the general public still believe ASD is caused by environmental factors. Some listed by respondents were food additives, medications, vaccines, and parenting techniques

Evaluation of a Technology-Based Survivor Care Plan for Breast Cancer Survivors: Pre-Post Pilot Study.

BACKGROUND: As of 2016, almost 16 million individuals were cancer survivors, including over 3.5 million survivors of breast cancer. Because cancer survivors are living longer and have unique health care needs, the Institute of Medicine proposed a survivor care plan as a way to alleviate the many medical, emotional, and care coordination problems of survivors. OBJECTIVE: This pilot study for breast cancer survivors was undertaken to: (1) examine self-reported changes in knowledge, confidence, and activation from before receipt to after receipt of a survivor care plan; and (2) describe survivor preferences for, and satisfaction with, a technology-based survivor care plan. METHODS: A single group pretest-posttest design was used to study breast cancer survivors in an academic cancer center and a community cancer center during their medical visit after they completed chemotherapy. The intervention was a technology-based survivor care plan. Measures were taken before, immediately after, and 1 month after receipt of the survivor care plan. RESULTS: A total of 38 breast cancer survivors agreed to participate in the study. Compared to baseline levels before receipt of the survivor care plan, participants reported increased knowledge both immediately after its receipt at the academic center (P\u3c.001) and the community center (P\u3c.001) as well as one month later at the academic center (P=.002) and the community center (P\u3c.001). Participants also reported increased confidence immediately following receipt of the survivor care plan at the academic center (P=.63) and the community center (P=.003) and one month later at both the academic center (P=.63) and the community center (P\u3c.001). Activation was increased from baseline to post-survivor care plan at both the academic center (P=.05) and community center (P\u3c.001) as well as from baseline to 1-month follow-up at the academic center (P=.56) and the community center (P\u3c.001). Overall, community center participants had lower knowledge, confidence, and activation at baseline compared with academic center participants. Overall, 22/38 (58%) participants chose the fully functional electronic survivor care plan. However, 12/23 (52%) in the community center group chose the paper version compared to 4/15 (27%) in the academic center group. Satisfaction with the format (38/38 participants) and the content (37/38 participants) of the survivor care plan was high for both groups. CONCLUSIONS: This study provides evidence that knowledge, confidence, and activation of survivors were associated with implementation of the survivor care plan. This research agrees with previous research showing that cancer survivors found the technology-based survivor care plan to be acceptable. More research is needed to determine the optimal approach to survivor care planning to ensure that all cancer survivors can benefit from it

Control of inherited structures and mechanical heterogeneities on the internal deformation of the Dolomites Indenter, eastern Southern Alps: a multi-scale analogue modelling study

During the Cenozoic evolution of the Alps, the Adriatic plate is traditionally considered as a rigid indenter. The structure of the northernmost part of the Adriatic plate in the eastern Southern Alps of Italy and Slovenia, referred to as Dolomites Indenter (DI), however, demonstrates significant internal deformation. Mostly Miocene shortening is accommodated within a WSW-ENE striking, S-vergent fold-and-thrust belt overprinting a pre-existing platform-basin geometry related to Jurassic extension. In this contribution we present two new sets of physical analogue experiments, addressing the effect of lateral crustal heterogeneities on the internal deformation of the DI on crustal- and lithospheric scale. The upper crust of the western Trento platform (western DI) is compositionally heterogeneous linked to Permian intrusives and extrusives (i.e., Athesian Volcanic Complex). Together with inherited basement structures this lateral heterogeneity, which strengthened the platform locally, is key for understanding upper crustal deformation and surface uplift patterns associated with Miocene basin inversion. We present brittle crustal-scale analogue experiments with inversion of pre-scribed platform-basin geometries, which indicate that variations in thickness, shape, and basement structure of especially the western platform (WP) have impact on timing and uplift of the DI’s upper crust. The mentioned variations in crustal composition, lead, compared to the reference model with simple platform-basin geometry, to (i) overall fewer thrust sheets, (ii) footwall cut-offs of the frontal thrust further in the hinterland, and to (iii) longer and flatter flats of the frontal thrust. Regarding the topographic evolution, a variation in, e.g., basement structure shows strain localization at the margin of the basal plate and stronger uplift within the southern part of the WP compared to limited uplift of the northern WP, which is consistent with documented little vertical movement north of the Valsugana fault system since the Jurassic. On the scale of the lithosphere, new analogue experiments with pre-scribed platform and basin geometries in the upper crust show similar lateral variations in thrust fault orientation across transfer zones as crustal-scale analogue models (Sieberer et al., 2023). Additionally, lateral variability of ductile lower crustal thickness predicts stronger uplift in areas of thicker lower crust. Documented thickening of the lower crust in some parts of the Southern Alps close to areas of higher uplift, tentatively interpreted being Miocene in age (Jozi Najafabadi et al., 2022), might support this finding. Ultimately our crustal and lithosphere-scale modelling predictions will be validated by high resolution low-temperature thermochronological data which cover the entire Dolomites Indenter
