Purpose Although natural science disciplines significantly contribute to sustainable development goals (SDGs), little research attends to how higher education institutions (HEIs) influence the development of leadership skills needed among sustainability leaders. This paper aims to examine the leadership development experiences of natural scientists at the forefront of disciplines associated with SDGs to identify barriers and drivers to sustainability leadership skills development at HEIs. Design/methodology/approach A mixed-methods comparative study was used, integrating qualitative interviews among 21 natural scientists and 11 non-scientists, two focus group discussions and a cross-sectional survey of 221 leaders. The theory of planned behaviour was used as the analytical frame to identify themes emerging from the data as facilitators or barriers to leadership development. Findings There was a statistically significant difference between scientists and non-scientists in the attitudes, beliefs and perceptions that drive participation in leadership development activities. Attitudes belittling leadership skills, limited integration of leadership skills in medical, engineering and agricultural curricula and a social identity of superior learning efficacy impede natural scientist students at HEIs from engaging in leadership development. Research limitations/implications Further research using a larger sample could assess the prevalence and effect of the drivers and barriers on sustainability leadership effectiveness. Practical implications Beyond integrating leadership skills in HEIs curricula, the development of sustainability leadership requires deliberate elevation of the value of leadership skills within natural sciences, specifically by addressing attitudes, beliefs and workload challenges that impede scientists' engagement in co-curricular activities. Originality/value Integrating multiple disciplines provides generalised insights into the context of leadership development among natural scientists at HEIs. This study identifies specific drivers and barriers affecting leadership development at HEIs in a developing country setting.

Abstract Background Artemisinin-based combination therapy (ACT), the treatment of choice for uncomplicated falciparum malaria, is unaffordable and generally inaccessible in the private sector, the first port of call for most malaria treatment across rural Africa. Between August 2007 and May 2010, the Uganda Ministry of Health and the Medicines for Malaria Venture conducted the Consortium for ACT Private Sector Subsidy (CAPSS) pilot study to test whether access to ACT in the private sector could be improved through the provision of a high level supply chain subsidy. Methods Four intervention districts were purposefully selected to receive branded subsidized medicines - “ACT with a leaf”, while the fifth district acted as the control. Baseline and evaluation outlet exit surveys and retail audits were conducted at licensed and unlicensed drug outlets in the intervention and control districts. A survey-adjusted, multivariate logistic regression model was used to analyse the intervention’s impact on: ACT uptake and price; purchase of ACT within 24 hours of symptom onset; ACT availability and displacement of sub-optimal anti-malarial. Results At baseline, ACT accounted for less than 1% of anti-malarials purchased from licensed drug shops for children less than five years old. However, at evaluation, “ACT with a leaf” accounted for 69% of anti-malarial purchased in the interventions districts. Purchase of ACT within 24 hours of symptom onset for children under five years rose from 0.8% at baseline to 26.2% (95% CI: 23.2-29.2%) at evaluation in the intervention districts. In the control district, it rose modestly from 1.8% to 5.6% (95% CI: 4.0-7.3%). The odds of purchasing ACT within 24 hours in the intervention districts compared to the control was 0.46 (95% CI: 0.08-2.68, p=0.4) at baseline and significant increased to 6.11 (95% CI: 4.32-8.62, p Conclusions These data demonstrate that a supply-side subsidy and an intensive communications campaign significantly increased the uptake and use of ACT in the private sector in Uganda.
