A new flying wing design has been developed at the Unmanned Systems Lab (USL) at Virginia Tech to serve delivery and remote sensing applications in the developing world. The fully autonomous unmanned aerial vehicle (UAV), named EcoSoar, was designed with the goal of creating a business opportunity for local entrepreneurs in low-resource communities. The system was developed in such a way that local fabrication, operation, and maintenance of the aircraft are all possible. In order to present a competitive financial model for sustained drone services, EcoSoar is made with reliable low-cost materials and electronics. This paper lays out the rapid prototyping and flight experiment efforts that went into polishing the design, test results from an EcoSoar centered drone workshop in Kasungu, Malawi, and finally a range optimization study with flight test validation. / Master of Science / A new humanitarian drone has been developed at the Unmanned Systems Lab (USL) at Virginia Tech. The unmanned aerial vehicle (UAV), named EcoSoar, was designed with the goal of creating a business opportunity for local entrepreneurs in low-resource communities. In order to be a viable solution in the developing world EcoSoar utilizes customizable 3D-printed parts and wings made from cheap materials like posterboard and packing tape. In addition, tools for building the drone have been developed in such a way that anyone can learn to construct and operate EcoSoar regardless of experience. This paper lays out the engineering efforts that went into the design, lessons learned from an EcoSoar-centered workshop in Kasungu, Malawi, and finally offers an upgraded design.

The privileges of integration with the global economy have led developing countries to embark on a path of liberalisation and globalisation. This resulted in rapid growth of inward and outward foreign direct investment from developing countries. In the last two decades there is an increasing trend of outward FDI from developing countries to both developed and developing countries. This dissertation focuses on exploring the literature on outward FDI from developing countries, and internationalisation process of developing country multinationals which are considered to be carriers to investment across international borders. The study has examined the two main strands of literature on outward FDI from developing countries – determinants of outward FDI and internationalisation process. Findings of the systematic review show that there is a dearth of studies in this area of research. Except a number of studies on China and countries of East and South East Asia, there is very limited evidence on outward FDI from developing countries. There is a set of studies on Africa that examine South-South investment flows. Studies on other major developing countries are either non-existent or lack in comprehensiveness. Some studies resulted in contradictory findings about the determinants of outward FDI. This raises the question of sensitivity of variables across geographical locations and time periods, which has not been researched before. Studies on outward FDI also do not make a clear distinction between South-South and South-North FDI flows. Other aspects like sovereign wealth funds and commodity price boom have been ignored in the literature. It is important to investigate outward FDI flows from the major developing economies because of its sheer scope to contribute to academic literature, its policy implications, and also because of its potential to bring development to some of the most impoverished parts of the world.

Business need required a holistic and focussed framework for best practices in the functioning of effective virtual teams, despite the fragmented nature of empirical studies in this field. This study endeavoured to explore the best practices in the functioning of effective virtual teams against four prominent and unique themes linked to purpose, processes, people and technology. The value of this study does not vest in the existence of virtual teams, but in their orderly operation, in terms of best practice and the value proposition of effectiveness. Following an exploratory qualitative strategy, the research was conducted according to the interpretivist branch of the phenomenological tradition, with a transcendental orientation in the social research field. A qualitative multi-case research design for the empirical study was selected, resulting in a non-probability sample within the software sector of the technology industry in South Africa. An original and pre-tested Lime Survey 2.0+ electronic questionnaire instrument was utilised as the instrument to collect information within a cross-sectional time horizon, to work in synchronisation with the collaborative asynchronous electronic architecture of virtual teams. Content analysis was applied to analyse data. The main findings indicated that effective virtual teams purposefully orientate themselves toward excellence through electronic management systems, a specific value system, with a knowledge seeking focus, and a seamless linkage in electronic infrastructure, applications, and platforms which contribute to the functionality of the effective virtual team. The main recommendations were that a pre-existing, functional, collaborative, integrated, electronic management system is regarded as the primary step in founding an effective virtual team. The focus of organisational leadership should be to embrace a holistic value system approach encapsulating specific elements of excellence, such as trust and independence. Human networking practices pursuing and sustaining knowledge are regarded as the key enabler for functioning of effective virtual teams. Lastly, a focussed seamless interface between the various electronic applications, platforms and infrastructures is recommended. / Human Resource Management / D. Com. (Human Resource Management)

Thesis (PhD (Surgical Sciences. Ophthalmology))--Stellenbosch University, 2008. / Purpose: To evaluate the outcome of primary adult optical penetrating keratoplasty (PKP) at a public health service hospital of a developing country. Patients and Methods: A retrospective review was performed of the medical records of every patient 12 years of age or older who underwent PKP for keratoconus, corneal edema, stromal scarring, or stromal dystrophy at King Khaled Eye Specialist Hospital in the Kingdom of Saudi Arabia between January 1, 1997, and December 31, 2001, and for whom a minimum of 3 months’ follow-up was available. Results: Of 910 eyes that met the inclusion criteria, there were 464 eyes with keratoconus, 188 eyes with corneal edema, 175 eyes with stromal scarring, and 83 eyes with stromal dystrophy. For the entire group, the probability of graft survival was 96.7% at 1 year, 86.2% at 3 years, and 80.9% at 5 years. Five-year survival probability was best with keratoconus (96.1%), followed by stromal dystrophy (85.9%), stromal scarring (71.1%), and corneal edema (40.3%). The probability of graft survival differed significantly among the surgical indications at all postoperative intervals (P<0.001). Factors associated with a significantly increased risk of graft failure on multivariate Cox proportional hazard regression analysis included increasing donor tissue age (P = 0.005) and decreasing recipient graft size (P = 0.02). Final visual acuity of 20/40 or better was obtained in 409 (44.9%) eyes. Visual acuity of 20/40 or better was obtained in 336 (72.4%) eyes with keratoconus and in 53 (63.9%) eyes with stromal dystrophy but in only 11 (6.3%) eyes with stromal scarring and 9 (4.8%) eyes with corneal edema (P<0.001). Overall, improvement in vision occurred in 750 (82.4%) eyes, remained the same in 97 (10.7%) eyes, and worsened in 63 (6.9%) eyes. Conclusions: The present study has conclusively demonstrated that primary adult optical PKP can be performed at a public health facility in the Kingdom of Saudi Arabia with graft survival and visual results that are comparable to those obtained in welldeveloped Western facilities. This success is attributed to the presence of a suitable infrastructure that provides modern eye care facilities, donor tissue, and pharmaceuticals to patients who have access to preoperative screening and evaluation, surgical intervention, and postoperative care by well-trained ophthalmologists and ancillary support personnel.

Customers’ satisfaction is a decisive factor in the development process of business which has also an effective impact on contributing a country's GDP. Private banks have been emerged over the time in developing countries where customers’ satisfaction is the driven force of banking industry investigated in Bangladesh. In this study a conventional American Customer Satisfaction Index model has been used over Bangladesh to compare overall performance of banking industry. Customers’ satisfaction in Bangladesh has been measured from the different angle of customers’ perception based on their portfolio. This research has been designed on a quantitative approach followed by survey research method. Questionnaire was administered to collect data through objective list as well as physical interaction with the respondents from different locations in the capital city of Bangladesh named Dhaka. Collected data had been analyzed applying Partial Latent Square (PLS) software program. The study outcomes showed that the perceived quality is the main determinant factor on customer satisfaction towards banks in Bangladesh. It also revealed that significant relationship exists between customers’ satisfaction and customers’ loyalty. The revised model in 2016 represents the benchmark scores of customers’ satisfaction in Bangladesh lagged behind consecutively 18 and 13 scores than that of USA and Taiwan. Considering the study results, we summed the quality of service leads to satisfied customers in turns towards customers loyalty. Banks also can get competitive advantage by evaluating all classes of customers equally through providing superior services to them.

The goal of this research is to establish a link between investments in information and communication technology (ICT) and economic growth in the context of countries that are currently classified by the international community as transitional economies (TE). More specifically, in this study we focus on the relationship between ICT and one of the determinants of economic growth, total factor productivity (TFP). Neoclassical growth accounting and the theory of complementarity provide the theoretical framework on which we build this research. By combining the data obtained from two sources, the World Bank Database and the IT Yearbook, we were able to construct a 10-year data set for 18 TEs spanning the period from 1993 to 2002.Our inquiry is structured as a seven-step process that utilizes six data analytic methods. The first step in our investigation involves Cluster analysis (CA) with the purpose of determining whether or not the selected set of TEs is homogenous. Use of CA allowed us to identify two distinct groups of TEs in our sample, which suggests the heterogeneity of the sample.In the second part of our inquiry, we employ Decision Tree (DT) analysis with the goal of investigating the differences between the clusters of TEs that were generated by the CA in the previous step. We were able to determine that one of the groups of TEs, the "leaders," appears to be wealthier than the other group, the "majority."In the next step of our investigation, we perform Data Envelopment Analysis (DEA) to determine the efficiency of the TEs in our set. We were able to determine that the "leaders" are more efficient than the "majority" not only in terms of the production of the output, but also in terms of the utilization of the inputs.The fourth part of our investigation takes advantage of the DT analysis with the purpose of obtaining the insights into the nature of the differences between the efficient and inefficient TEs. By incorporating the results of the CA into DT analysis we were able to construct the model that suggests, with the high degree of precision, some of the criteria according to which the efficient TEs differ from the inefficient ones.The fifth stage of our investigation involves the use of the Translog regression model for the purpose of determining whether or not there exists a set of investments that are complementary to the investments in ICT. We have determined that there exists a statistically significant interaction effect between the investments in ICT and other variables, representing state of labor, as well as capital investments.The sixth part of our investigation relies on using Structural Equation Modeling (SEM) implemented with Partial Least Squares(PLS)to test for the presence of the relationship between the investments in ICT and the unexplained part of the macroeconomic growth, TFP. We were able to establish the presence of the relationship between the two constructs of our conceptual model, "ICT Capitalization" and "TFP" for the "leaders" group of our sample. The construct "ICT Capitalization" was represented by the three ratio measures, all of which contain variable "Annual investment in telecom" in the denominator, while the Malmquist Index and its components, TC and EC., represented the construct "TFP." Thus, it allows us to state that we have established the presence of the relationship between the investments in ICT and TFP.The last step of the data analysis involves using Classification DT and Neural Network (NN) analyses with the aim of investigating the reasons why some of the TEs exhibit statistically significant relationship between the investments in ICT and TFP, while other TEs do not. We were able to determine that one of the reasons why the "leaders" exhibit the statistically significant relationship between the investments in ICT and TFP is that they have higher level of inputs and more efficient processes of converting the inputs into the outputs than the "majority."

Background: Knowledge translation models to address existing knowledge gaps in different areas of speech-language pathology practice are providing researchers and clinicians the opportunity to improve efficiency and effectiveness of service delivery. As a developing context, public health care in South Africa can scarce afford the luxury of wasting resources and finances on interventions that are inefficient or without proven benefit given the increasing prevalence of chronic burden of disease such as stroke and traumatic related injury, both of which has dysphagia as a symptom. The outcome of the manner, efficiency and consistency of traditional models of dysphagia management currently being implemented in this context were compared to a pre-existing theoretically proven free water protocol for dysphagia management. Method: The primary aim of the current study was to enable knowledge-to-action translation in dysphagia management by determining the feasibility of using a free water protocol for stroke or traumatic brain injured patients presenting with dysphagia in an acute government hospital setting in Gauteng, South Africa. A mouth care training protocol was developed for nurses as a component of the free water protocol. Nurse perceptions on the training and implementation of mouth care were explored. The quantitative aims investigated if there was a difference between traditional and free water management in terms of a) the occurrence of aspiration pneumonia, b) amount of water intake and c) length of hospitalisation. 139 Nurses and 46 patients with dysphagia were participants. A mixed method design was used. The study was conducted in two phases, phase one comprised the ethnography and the nurse training component. Phase two was quantitative and comprised implementation of the free water protocol by the researcher. Thematic content analysis was used for the qualitative data. Quantitative data was analysed using inferential statistics. Results: The mouth care training protocol for nurses was efficient and effective for the current context. Nurses engaged positively with the study by implementing mouth care successfully when necessary for the dysphagic patients. This combined with consistent daily management of dysphagia with patient involvement, facilitated patient compliance, adequate levels of water intake, with no cases of dehydration, and no incidence of aspiration pneumonia at the end of the intervention period. The comparison group in contrast who received the traditional model of dysphagia management showed longer period of hospitalisation and higher consumption of liquids despite recommendations for liquid restricted diets. There were seven cases of aspiration pneumonia at the end of the intervention period in the comparison group. Conclusions & Implications: Despite no statistically significant differences between the study and comparison groups on the specified outcome measures, clinically significant differences were noted. The method employed in the study seemed to facilitate knowledge translation of the free water protocol to a public hospital context in South Africa. The findings of the study suggested that a collaborative partnership between the speech-language pathologist and nurse was attainable and this seemed to have multifaceted mutual benefits to the patient, institution and the respective professions. Improved monitoring of service provision, implementation of protocols based on contextual evidence, importance of knowledge translation in a developing context and an expanded role of the speech-language pathologist responsive to the needs of the context and patient population were some of the implications that arose from the study.
