A Curriculum Model: Engineering Design Graphics Course Updates Based on Industrial and Academic Institution Requirements

Engineering design graphics courses taught in colleges or universities should provide and equip students preparing for employment with the basic occupational graphics skill competences required by engineering and technology disciplines.  Academic institutions should introduce and include topics that cover the newer and more efficient graphics techniques and technologies developed through research by academic institutions and professional organizations as well as information obtained from experienced engineering design graphics practitioners.  This paper presents the systematic approach used at the University of Nebraska at Kearney (UNK), Department of Industrial Technology (ITEC), to update and improve its existing multidiscipline engineering design graphics course.   Twenty five engineering design graphics course syllabi, all from programs accredited by either the Association of Technology, Management, and Applied Engineering (ATMAE) or the Accreditation Board for Engineering and Technology (ABET), were reviewed in this study.  A review of the course syllabi identified 20 of the most commonly taught engineering design graphics topics.  The 20 topics were used to develop a survey instrument subsequently sent to the top 10 employers of ITEC students majoring in Construction Management, Industrial Distribution, and Telecommunications Management.  The results obtained from the employer survey were analyzed and used to update the introductory engineering design graphics course at UNK so that engineering design graphics topics taught are consistent with academia and kept current and relevant to the needs of industry

Independent and combined effects of improved water, sanitation, and hygiene, and improved complementary feeding, on child stunting and anaemia in rural Zimbabwe: a cluster-randomised trial.

BACKGROUND: Child stunting reduces survival and impairs neurodevelopment. We tested the independent and combined effects of improved water, sanitation, and hygiene (WASH), and improved infant and young child feeding (IYCF) on stunting and anaemia in in Zimbabwe. METHODS: We did a cluster-randomised, community-based, 2 × 2 factorial trial in two rural districts in Zimbabwe. Clusters were defined as the catchment area of between one and four village health workers employed by the Zimbabwe Ministry of Health and Child Care. Women were eligible for inclusion if they permanently lived in clusters and were confirmed pregnant. Clusters were randomly assigned (1:1:1:1) to standard of care (52 clusters), IYCF (20 g of a small-quantity lipid-based nutrient supplement per day from age 6 to 18 months plus complementary feeding counselling; 53 clusters), WASH (construction of a ventilated improved pit latrine, provision of two handwashing stations, liquid soap, chlorine, and play space plus hygiene counselling; 53 clusters), or IYCF plus WASH (53 clusters). A constrained randomisation technique was used to achieve balance across the groups for 14 variables related to geography, demography, water access, and community-level sanitation coverage. Masking of participants and fieldworkers was not possible. The primary outcomes were infant length-for-age Z score and haemoglobin concentrations at 18 months of age among children born to mothers who were HIV negative during pregnancy. These outcomes were analysed in the intention-to-treat population. We estimated the effects of the interventions by comparing the two IYCF groups with the two non-IYCF groups and the two WASH groups with the two non-WASH groups, except for outcomes that had an important statistical interaction between the interventions. This trial is registered with ClinicalTrials.gov, number NCT01824940. FINDINGS: Between Nov 22, 2012, and March 27, 2015, 5280 pregnant women were enrolled from 211 clusters. 3686 children born to HIV-negative mothers were assessed at age 18 months (884 in the standard of care group from 52 clusters, 893 in the IYCF group from 53 clusters, 918 in the WASH group from 53 clusters, and 991 in the IYCF plus WASH group from 51 clusters). In the IYCF intervention groups, the mean length-for-age Z score was 0·16 (95% CI 0·08-0·23) higher and the mean haemoglobin concentration was 2·03 g/L (1·28-2·79) higher than those in the non-IYCF intervention groups. The IYCF intervention reduced the number of stunted children from 620 (35%) of 1792 to 514 (27%) of 1879, and the number of children with anaemia from 245 (13·9%) of 1759 to 193 (10·5%) of 1845. The WASH intervention had no effect on either primary outcome. Neither intervention reduced the prevalence of diarrhoea at 12 or 18 months. No trial-related serious adverse events, and only three trial-related adverse events, were reported. INTERPRETATION: Household-level elementary WASH interventions implemented in rural areas in low-income countries are unlikely to reduce stunting or anaemia and might not reduce diarrhoea. Implementation of these WASH interventions in combination with IYCF interventions is unlikely to reduce stunting or anaemia more than implementation of IYCF alone.

Local knowledge as a source of community resilience

Local knowledge can serve a source of local community resilience that provides an enabling capacity for people to sustain their livelihoods and adapt to environmental changes or new environments. This knowledge was evidenced as capable of resurfacing when contingent opportunities arise. This contribution draws upon case studies of emerging self-mobilised social learning processes in the recollection and application of agricultural knowledge as revealed in immigrant gardeners’ narratives in New York City, United States and narratives from relocated farming communities in Sebakwe, Zimbabwe. In these narratives the communities draw upon their reserves of local knowledge to respond to changes within their local environments. Such knowledge can serve as a source of community resilience through enabling people to sustain their livelihoods and community wellbeing, and thus adapt to environmental changes and displacement.Keywords: Local knowledge, community resilience, narratives
