Full textBackground and research problem: There have been claims in academic literature that social entrepreneurs, such as non-profit organisations and hybrid organisations that pursue social outcomes are architects or innovators of community development. However to date, there is no conclusive empirical evidence to support that claim. Main purpose of the study: The main purpose of this study was to gain an understanding of the opportunities created by social entrepreneurs, as architects of community development, in communities they operate; identify the main challenges that the social entrepreneurs face and come up with recommendations of how social entrepreneurs can deal with these challenges. For the purpose of the study, the focus was on communities especially those ravaged by various social ills. Research methodology: A mixed method approach was adopted as the study was underpinned by two paradigms namely, positivist and interpretivist philosophies. The survey strategy was used in conducting the inquiry. Data was collected using semi-structured questionnaires which were self-administered to 150 community members selected randomly. Semi-structured interviews were conducted with 20 respondents. Computer aided statistical method was used to analyse quantitative data while qualitative data was analysed using noncomputer aided thematic techniques. Main findings, conclusions and recommendations: The study found that the majority of social entrepreneurs studied have been making positive contributions to various aspects of community development. However, none of them has embraced the whole range of community development aspects that are needed for a holistic approach to comprehensive contribution. Reasons for failure to embrace a holistic approach include a lack of social entrepreneurship development framework, and various operational and political challenges. It is also important to mention that the research techniques used are not adequate to measure certain types of social impacts of the social entrepreneur's efforts. For these, additional social impact measuring techniques would need to be developed and employed.

Full textHumanity has experienced more than one pandemic in its history and is well aware of its consequences. In early 2020, the world was rocked by the Covid-19 pandemic, which rapidly spread to the world. Every State has had to introduce drastic measures. Tourism has been slowed down and banned at certain times. The severity of the problem is that the pandemic has a major negative impact on all areas of life, whose rehabilitation is difficult and whose losses are enormous. That is why the study of the problems of tourism business development in Ukraine under Covid-19 conditions is extremely topical.
Людство пережило не одну пандемію за свою історію і добре усвідомлює її наслідки. На початку 2020 року світ сколихнула пандемія Covid-19, яка швидко поширилася на світ. Кожній державі доводилося вводити рішучі заходи. Туризм уповільнений і заборонений у певний час. Серйозність проблеми полягає в тому, що пандемія має серйозний негативний вплив на всі сфери життя, реабілітація яких є складною, а втрати величезні. Тому вивчення проблем розвитку туристичного бізнесу в Україні в умовах Covid-19 є надзвичайно актуальним.

Full textJuliaca ya es una ciudad grande, que crece aceleradamente con desorden y por tanto hay caos entodo sentido, con su población próxima a 300 000 habitantes sin contar la población flotante. Tiene más de 350 asentamientos humanos que estructuran la urbanización, que es un fenómeno demótico actual propio del Perú y de los países del tercer mundo, estimulada por la migración rural y urbana regional y del sur del país, evidenciándose así en demografía el modelo de gravedad de Newton. En el curso de 75 años, desde 1940 que contaba con 6034 habitantes hasta 2007, la población de Juliaca se ha incrementado 50 veces, con una tasa anual de 4%, y se ha convertido en la primera ciudad más poblada del altiplano, la tercera en el sur del Perú después de Arequipa y Tacna, y la undécima ciudad más poblada del Perú. Este fenómeno ha generado vastísimos problemas sociales como el caos en el comercio, transporte, falta de seguridad, falta de infraestructura, servicios básicos de agua, desagüe, inundaciones; por tanto existe conmoción de la población a la centralidad y a la desatinada conducción del gobierno local que no se abastece para una administración adecuada y satisfactoria, por constituir Juliaca una ciudad que se agiganta progresivamente.Con estos antecedentes, Juliaca debe descentralizarse por lo menos en cinco distritos teniendo en cuenta su actual espacio urbanizado, incluido el actual Juliaca y otros cuatro distritos a partir del primer anillo (Circunvalación) que implica varios núcleos de desarrollo urbano. Esto debe ser tarea para las autoridades que buscan revertir el caos y desorden con la soluciónde problemas sociales.

Full textThe author focuses on property formalization, microfinance and their effects on empowering the poor in Peru. For this purpose, the author will first analyze the economic and social conditions in which the microfinance initiative has taken place in Peru as well as its informal economy. Then, the author will explain the advantages and disadvantages that microfinance and property formalization have had as economic tools used to confront the problem of collateral. The author argues that both economic tools, if used together, may have a greater impact in the poor’s economic empowerment. The poor’s economic empowerment will be understood as the decrease in interest rates in the microfinance sector. Hence, Peruvian Microfinance Institutions – represented by Peru’s leading MFI “Microfinanzas Prisma – will be analyzed through regression analyses with intervention variables to simulate the correlations between collateral and interest rates in the microfinance sector. The results demonstrate that formal property, although correlated with interest rates up to a certain point, may not have a significant correlation with interest rates beyond that point. The author will finally interpret the results of the empirical analyses and will make some recommendations that could be implemented as development policies. A proposal would be based on the joint use of microfinance and formal property to further decrease interest rates and therefore empower the individuals borrowing below the point at which collateral has no significance correlation with interest rates. Concepts such as social capital and community organization will be addressed to further enhance the impact of collateral on interest rates

Full textIndustrial symbiosis is a collaborative process of industries geographically located in an industrial park, which facilitates and enables an exchange of products, by-products and wastes to reduce the collective adverse impacts of the emission during the operation of these industries. However, IS faces a number of barriers. Importantly, it has been identified that there is a critical impediment to implementing future IS practices in the area. This is because of the number of barriers such as technical, regulatory, commercial as well as informational. In addition, there is an absence of a proven and well established evaluation methodology to identify the benefits of such practice. The true implications of IS might therefore remain underestimated, thereby failing to convince industry, government and the community to realize the opportunities IS can bring in attaining goals of sustainability in their operations.
The aim of this PhD research was to develop and trial a method for capturing the life cycle environmental, social and economic implications of industrial symbiosis in heavy industrial areas. This research was based on multi-disciplinary approach of examining environmental, social and financial aspects to develop an integrated method. In the Kwinana industrial Area (KIA), the primary research area in Western Australia, the opportunities were significant for such industrial symbiosis to happen because of the co-location of diverse industries. The research hypothesis that informs this thesis is that the assessment of implications of present IS might bring further opportunities for enhancing symbiosis between industries. Though the primary emphasis of the research was in the Kwinana Industrial Area, this approach could be applied to other heavy industrial areas. This site could be significant both nationally and internationally in providing a platform for business responses to regional sustainable development challenges, by documenting best practice and improving approaches for implementing industrial symbiosis.
This research addressed the objectives by using the developed Six Capitals Model (SCM) for identifying environmental, social and economic benefits. The values under these dimensions were analysed with regard to natural, ecosystem, human, social, financial and manufactured capitals for a project of wastewater reclamation for industrial use. Under the environmental dimension, the model revealed that resource conservation and resource security were achieved as a result of the operation of this project. These results are in line with the argument that industrial symbiosis secures and conserves resources due to the possibility of reclaiming the resources that were once discarded. Water contamination has been reduced as a result of the operation of this project. This indicator shows that there is an improvement in maintaining the ecosystem capital.
In terms of human capital, sharing information between industries and opportunities of sharing infrastructure and technology has been improved. Regarding community capital, sharing of information between industries and communities, has increased as a result of this project. Collaboration of government bodies, level of understanding about IS projects due to increasing communication between various stakeholders, and increase of employment opportunities are notable, as value has been generated for community capital since the project started. In terms of financial capital of the project, the majority of the participants did not gain any financial savings in terms of direct costs but rather accrued short term costs. This was due to the infrastructure cost involved as part of installation of pipes and pumps. It was also due to the high cost of the reclaimed water than the scheme water. In addition, the analysis showed that most of the participants of the project did not gain any savings in the indirect costs such as hidden and legal costs, such as permit costs, compliance costs, future fines and penalties. However, as part of manufactured capital, there were savings due to improved business opportunities as well as infrastructure, for business and community collectively.
The results of this thesis show that broader benefits of symbiosis can be achieved, not only from operation of the project, but also from the influence of processes of symbiosis. Among them are connection, communication and collaboration between the project partners. There has been a substantial increase in the networking of industries and formation of multi groups for addressing various issues faced by industry and community in the Kwinana. There has also been a further increase in the transparency of information dissemination and communication through industries council’s website. In addition, there has been an improvement in the rate of participation of community members and groups in the Communities and Industries Forum (CIF) which resulted in the formation of further stakeholder groups by industries council as a platform for addressing the issues of industries and communities.
IS practices strengthen the EIP concept and increase the chances of sustainable industrial development regionally due to collaboration of community of businesses and local and regional community. IS also increases the reputation and license to operate in the community. There are many advantages for using the Model developed in the thesis to assess the benefits of IS. First, the values of ecosystem values maintained are able to be accounted for in addition to natural capital values. The Six Capital Model can also account human capital values in addition to community capital. The Model also accounted the manufactured capital in addition to financial capital and it gives an opportunity to identify the value generated towards community and companies.
Finally, the Model enables a calculation of the internal costs and external costs and benefits so that industries are able to understand the real cost of the projects. One of the main advantages of this method is that with, right indicators, the intangible values of the IS process can also be assessed and reported.

Full textDenna avhandling berör problemlösning i plattformsutvecklingsprocesser. Ett problem avser etthinder som måste övervinnas för att nå ett önskat resultat, medan en lösning betecknas med deaktiviteter som krävs för att nå ett sådant resultat. Med plattform avses den teknologiska grund,bestående av ett antal element, som är avsiktligt planerade och utvecklade för att bilda engemensam struktur via vilken en ström av olika produkter kan utvecklas. Problemlösning iutvecklandet av plattformar är en icke-trivial uppgift eftersom plattformar måste tillgodose bådegemensamhet och särprägel i ett antal produkter. Vidare så är flera designarkitekturersammanflätade i utvecklandet av plattformar, vilket ger upphov till ökad komplexitet. Syftet meddenna avhandling är att undersöka plattformsutveckling från ett problemlösningsperspektiv, isyfte att svara på vilka problemlösningsaktiviteter som bedrivs i plattformutvecklingsprocesser,hur olika strategier för att söka efter lösningar i samband med problemlösning iplattformsutveckling är relaterade till varandra, samt hur problemlösning i plattformsutvecklingkan föreställas. Denna avhandling bygger på två empiriska studier av plattformsutvecklingsprocesseri telekommunikation och fordonsindustrin, och bygger på en kvalitativforskningsmetodik. Resultatet av denna undersökning är en iterativ och dynamisk modell förlösningsökning. Denna avhandling föreslår en skillnad mellan ett problem och ett fel iutvecklandet av telekommunikationsplattformar och fordonsplattformar. Lösningssökandeframstår som ett val mellan att engagera sig i problemlösning eller/och felkorrigering underutvecklandet av plattformar. Lösningssökande framstår också som en sammansmält process avsökande efter nödvändig input, output och de styrande lagar (dvs. lösningar) för att nå ett önskatmål. I denna process är analytisk sökande, riktat sökande, syntetiserad sökande, ochförvaltningen av både återkoppling och framåtkopplingning viktig.

Full textThe objective of the economic dispatch problem of electrical power generation is to schedule the committed generating unit outputs to meet the required load demand while satisfying the system equality and inequality constraints. The thesis formulates single area and multi-area Combined Economic Emission Dispatch (CEED) problem as single criterion, bi-criterion and multi-criteria optimisation problems based on fuel cost and emission criterion functions, constraints over the operational limits of the generator and the tie-lines, and requirements for a balance between the produced power and the system demand and power loss. Various methods, algorithms and softwares are developed to find solution of the formulated problems in single area and multi-area power systems. The developed methods are based on the classical Lagrange's and on the meta-heuristic Particle Swarm Optimisation (PSO) techniques for a single criterion function. Transformation of the bi-criteria or multi-criteria dispatch problem to a single criterion one is done by some existing and two proposed in the thesis penalty factors. The solution of the CEED problems is obtained through implementation of the developed software in a sequential way using a single computer, or in a data-parallel way in a Matlab Cluster of Computers (CC). The capabilities of the developed Lagrange's and PSO algorithms are compared on the basis of the obtained results. The conclusion is that the Lagrange's method and algorithm allows to receive better solution for less computation time. Data-parallel implementation of the developed software allows a lot of results to be obtained for the same problem using different values of some of the problem parameters. According to the literature papers, there are many algorithms available to solve the CEED problem for the single area power systems using sequential methods of optimisation, but they consume more computation time to solve this problem. The thesis aim is to develop a decomposition-coordinating algorithm for solution of the Multi Area Economic Emission Dispatch (MAEED) problem of power systems. The MAEED problem deals with the optimal power dispatch inside and between the multiple areas and addresses the environmental issue during the economic dispatch. To ensure the system security, tie-line transfer limits between different areas are incorporated as a set of constraints in the optimisation problem. A decomposition coordinating method based on the Lagrange's algorithm is developed to derive a set of optimal solutions to minimize the fuel cost and emissions of the multi-area power systems. An augmented function of Lagrange is applied and its decomposition in interconnected sub problems is done using a new coordinating-vector. Task-parallel computing in a Matlab Cluster is used to solve the multi-area dispatch problem. The calculations and tasks allocation to the Cluster workers are based on a shared memory architecture. Implementation of the calculation algorithm using a Cluster of Computers allows quick and simpler solutions to the multi-area CEED problem. The thesis applied the developed algorithms for the various problem formulation scenarios, i.e. fuel cost and emission function with and without valve point loading effect, quadratic and cubic fuel cost and emission functions. The various IEEE benchmark models are used to test the developed Lagrange's and PSO algorithms in the sequential, data-parallel, and task-parallel implementations. Developed methods, algorithms and software programmes can be applied for solution of various energy management problems in the regional and national control centres, smart grid applications, and in education and research institutions.
