- Description: The Western Indian Ocean hosts the second largest coastal population on the planet and supports 4 million tons of fish catches annually yielding $943 million in revenues and employment. However, it has been warming at a rate faster than any other region of the tropical oceans over the last century thereby placing the challenges of fluctuating fish supply and changes in ocean productivity on coastal communities. With the global food system under mounting pressure, governments need to understand the relationship between fish supply and food security to avoid overseeing the important role fish and fisheries play in ensuring food security. This study provides an alternative view and measurement of food security at a national level by assessing the impact that macroeconomic variables and climate change have on fish supply in Kenya, South Africa, and Tanzania as case study countries of the Western Indian Ocean. Vector Error Correction Models were run to analyse the impact of economic growth, fishing effort, lending interest rates, and climate change on marine food security for the period of 1980-2016. Agricultural employment was used as a proxy for fishing effort. In general, the relationship between fish supply and fishing effort is negative in the short run and positive in the long run for Kenyan marine fisheries, South African total capture and marine fisheries, and Tanzanian capture fisheries. These results therefore oppose the theoretical expectations. Sea surface temperature, as a proxy of climate change, was found to have a negative impact overall on fish supply and therefore exerts a negative impact on marine food security in all three countries. The results emphasise the need to use disaggregated fisheries statistics to better understand the complex relationship between macroeconomic variables and fish supply. By doing so, more effective food security policies can be created in attempt to mitigate the potential negative impacts of climate change on marine food security in the Western Indian Ocean.

The quality of tertiary healthcare in the Port Elizabeth - Eastern Cape province hospital complex

- Description: The goal of this study was to carry out a comprehensive assessment of the quality of healthcare in the Port Elizabeth Hospital Complex in the province of the Eastern Cape in South Africa. The assessment was made on the basis of the perceptions of patients of the features of the hospital and the services which it provides to patients. A quantitative research design was adopted to conduct the study. The data was derived from a questionnaire which the research assistants administered to patients in a number of surgical clinics in the hospital. Across-sectional sample of 350 patients, who were making their first follow-up visits after having previously been admitted to the hospital to undergo surgical procedures, was obtained by making use of convenience sampling. The researcher made use of the modified SERVQUAL scale for hospital services in order to measure the extent to which the participants agreed with statements pertaining to five specific dimensions of the quality of service, namely, tangibles, reliability, responsiveness, assurance, and empathy. The overall gap score was negative (-0.52), which indicates that the respondents perceived that the quality of healthcare which the hospital provided was unsatisfactory. Although the gap scores for each of five of the dimensions of quality were negative, the two dimensions whose gap scores reflected the highest levels of dissatisfaction were reliability (-0.66) and responsiveness (-0.63). The findings of this study could assist the Department of Health of the Eastern Cape Provincial Government to appreciate the perceptions of the public of the quality of healthcare which the Port Elizabeth Hospital Complex provides to patients. The recommendations which are made on the basis of the findings of this study could assist policymakers and members of the senior management of the hospital complex to formulate policies which result in substantial improvements in the quality of healthcare in the hospital complex. Further research is still needed to identify the factors which adversely affect the performance of the staff of the hospital and limit their ability to provide satisfactory healthcare consistently to patients.
