Determinants of export performance among small to medium enterprises in Zimbabwe

Karambakuwa, Tapuwa Roseline January 2017 (has links)
There is consensus that Small to Medium Enterprises (SME) exports play a critical role in the development of economies. It has been widely acknowledged in empirical research done around the world that small businesses make a significant contribution to economic development, employment, competitiveness and the reduction of regional disparities. However, empirical literature gives conflicting evidence on the determinants of export performance among SMEs. The study contributes towards the debate on SME exports by: (i) investigating the variables that determine export performance among SMEs in Zimbabwe (ii) establishing the competi-tiveness of Zimbabwe’s exports and (iii) ascertaining the major constraints faced by SME ex-porters in Zimbabwe The researcher gathered data from 120 SMEs and 10 institutions in Zimbabwe for the period 2009 to 2015. SME samples were chosen from Harare, Mashonaland Central and Mashonaland East provinces while all 10 of the institutions were chosen from Harare province. Convenient non-probability sampling method was used to select SMEs while stratified sampling technique was applied in the selection of institutions. Both qualitative and quantitative research methods were employed. For the quantitative approach, panel data ordinary least squares method was used in the form of the gravity model of trade. Export intensity (used as a measure of exports) was regressed against support institutions, business ownership, research & development, educational years, use of export processing zones, product type, export years, firm size, firm age, gender, distance from trading partner, Gross Domestic Product (GDP) of trading partner, and GDP of Zimbabwe. The random effects estimation method was used, basing on results from the Durbin-Wu-Hausman test. The null hypothesis was based on the premise that the variables under study do not determine export intensity of SMEs in Zimbabwe. Other null hypothesis were that the major constraint faced by SME exporters in Zimbabwe is not access to finance and that Zimbabwe’s exports are not competitive in the mining, agricultural and manufacturing sectors. The revealed comparative advantage index was computed to measure the competitiveness of Zimbabwe’s exports.For the qualitative approach, the study used the triangulation method which involved combining and utilising the questionnaire, interviews and focus group discussions. The results from the study indicated that following variables increased export intensity of Zimbabwean SMEs; business ownership, use of export processing zones, export years, firm size, and GDP of trading partner. The following variables have an inverse relationship with the export intensity of Zimbabwean SMEs: gender, distance from trading partner and research & development. The results also indicated that these further variables do not determine the export intensity of SMEs in Zimbabwe: support institutions, years of education, product type, firm age and GDP of Zimbabwe. The major constraint faced by exporting SMEs in Zimbabwe is limited access to finance. Zimbabwe is competitive in the agricultural and mining sector exports, but not in manufacturing sector exports The policy implication of the findings is that SME support needs to go beyond support institutions when it comes to SME export promotion. Further SMEs in the agriculture and mining sectors need to be promoted for export growth since Zimbabwe is competitive in these sectors. However the manufacturing sector cannot be ignored, since many economies have developed due to exports of manufactured products and a country needs to have balanced export growth in both primary and manufacturing sectors. In order to have motivated, career SME exporters, entrepreneurship education should begin from primary school right up to university so as to improve entrepreneurial aspirations, attitudes and behaviour in the long run.

The British anti-shipping campaign in the Mediterranean 1940-1944 : comparing methods of attack

Hammond, Richard James January 2011 (has links)
From the Italian declaration of war on 10 June 1940 through to the end of December 1944, the British and their allies waged a major campaign against Axis shipping in the Mediterranean. Uniquely for the British, this campaign took the form of a combined arms offensive throughout its conduct, and utilized all four methods of attacking shipping; surface vessels, submarines, aircraft and mine warfare. This thesis approaches the campaign thematically, examining each of the four methods individually. The priority given to the campaign, the forces and equipment available throughout, the tactics used and their development, the successes achieved in numbers and tonnage of merchant vessels sunk and the losses in numbers and casualties are all considered for each method. By examining these factors and the relevant quantitative data, the efficacy of each form of attack is determined and a final comparison of the four different methods made. The thesis concludes that overall, torpedo aircraft were the most effective method due to their ratio of high success and low number of personnel casualties, despite considerable losses of aircraft. Submarines were also very successful but ultimately more costly. The thesis demonstrates that mine warfare might well have achieved significant results had a greater priority been placed on it and that surface vessels no longer retained the ability to operate successfully for sustained periods in an anti-shipping role unless in an area of aerial and naval superiority.

Autonomus sea trade, possibility for the near future? : A study on the possibility and probability of unmanned vessel trade, economical sustainability and willingness from ship and cargo owners. / Autonom sjöfart, möjlig för handeln i snar framtid? : En studie om möjligheten och troligheten att ha obemannade fartyg i handelsflottan, ekonomisk hållbarhet och villighet från rederier och lastägare.

Modin, Albert January 2022 (has links)
The advanced technology has influenced every industry including the automotive sector, communication industry, maritime, and electronic sector. Through a qualitative research method this study aims to explore the possibility of employing unmanned and automated sea vessels in sea trade along with its major benefits and challenges to get a clearer view of where and when unmanned and automated sea vessels is going to change the future of the maritime sector. It also includes the willingness of ship owners and cargo operators to adopt the new technology. The findings indicate the existence of autonomous ships in the coming 10-years but legislation needs to be adopted for making the autonomous shipping possible for international trade. The conclusion being that autonomous ships are the future of the shipping or maritime industry. Cost-effectiveness is the potential benefit while legislation has been considered a major challenge. / Avancerad teknologi har påverkat varenda industi inkluderat bilindustrin, kommunikation, sjöfartsindustrin och den elektroniska sektorn. Genom en kvalitativ undersökningsmetodförsöker den här studien utforska möjligheten av användningen av obemannadeochautonoma fartyg inom handelsflottan tillsammans med dess största fördelar ochutmaningar för att få en bättre bild av var och när autonoma fartyg kommer att bliframtiden för den maritima sektorn. Den inkluderar även villigheten från redareochlastägare att ta till sig den nya teknologin. Resultaten visar på en trolighet att nybyggeninom en 10 års period kommer vara planerade men lagstiftningen måste ändras för attgöra autonoma båtar möjlig för internationell handel. Slutsatsen är att autonomafartygär framtiden för sjöfarten och den maritima industrin där kostnadseffektivitetenär denstörsta fördelen och lagstiftning anses vara den största utmaningen

What makes a passenger ship a legend: The future of the concept of legend in the passenger shipping industry

Coggins Jr., Andrew Oscar 16 December 2004 (has links)
Cruising, a ten million plus passenger, multi-billion dollar, world-wide industry, is one of tourism's fastest growing sectors. With many new ships entering the market each year, ships must capture the public imagination in order to compete. Over the years the ships that have done this have become legends. This study investigates the qualities necessary for a passenger ship to be identified as a legendary ship and asks how companies make their ships stand out as legends. This study proposes that legendary ships, "grand hotels of the sea," are extensions of other hospitality and tourism legends. Using the Grounded Theory Approach, in which the theory emerges from data, notable ships and their properties were identified from the literature. Integration of categories, factors, and their constituent properties under a Constant Comparative Method created a model of the legendary ship. A Delphi Panel tested and confirmed these properties as well as the study's initial model. It also produced a pool of legendary ships and additional properties. The results were further validated by the passenger shipping public using a world-wide electronic survey. Respondents rated intangible properties such as "External Appearance," "Internal Layout," "Quality of Service and Cuisine," "Funnel Design and Shape," "Repeat Passenger Patronage," "Legacy," "History," "Media Attention," "Speed," "Marine Technology," and "Route;" and the tangible properties of "Facilities, Fittings, and Furnishings," "Size," "Speed," "Marine Technology," and "Non Marine Technology," on their importance and named up to ten ships they considered legendary. Factor analysis was used to divide the properties into four composite factors - "Attractiveness," "Significance," "Power," and "Competitive Advantage." Cluster analysis of the ships produced four legend classifications - "Grand Legends," "Legends," "Demi Legends," and "Personal/Local Legends." Results confirmed the thesis that legendary status is based on superiority across a combination of factors. Those with more intangible properties were found to be stronger, with "Attractiveness," and "Significance" being the strongest. Significantly, no modern cruise ships placed in the top three legend classifications; except Queen Mary 2, built, marketed, and viewed as an ocean liner; indicating that the public views ocean liners and cruise ships as distinct entities. / Ph.
