The aim of this thesis is to explore investment opportunities of the Czech population, the ability of businesses to obtain needed capital for their investment plans and possibilities to obtain these funds from individuals through securities. The main part of this work is to evaluate the dependence between the securities markets and the growth of gross domestic product between 2006 - 2012. For the research, graphical and correlation analysis were used. Due to detected dependencies between gross domestic product and the bond market, issuance of bonds with a five-month delay of the positive fluctuation of gross domestic product was recommended. The final section is concentrates on prediction of the future development of the bond market, which proved to be unpredictable.

Das in diesem Beitrag beschriebene automatische Verfahren findet bei klassischen geodätischen Berechnungsaufgaben ausgehend von gegebenen Startgrößen (z. B. Festpunktkoordinaten, Messwerte) Berechnungsmöglichkeiten für alle anderen relevanten Größen. Bei redundanten Startgrößen existiert meist eine Vielzahl unterschiedlicher Berechnungsmöglichkeiten, die alle gefunden und deren Ergebnisse berechnet werden. Wenn die Berechnung mehrdeutig ist, aber nur endlich viele Lösungen existieren, werden alle Lösungen gefunden und berechnet. Durch den Vergleich unterschiedlicher Berechnungsergebnisse besteht die Möglichkeit, grobe Fehler in den Startgrößen aufzudecken und ein robustes Endergebnis zu generieren. Das Verfahren arbeitet nicht stochastisch, setzt also kein stochastisches Modell der Messwerte voraus. Die Beschreibung wird mit Beispielen illustriert. Das Verfahren wurde als Webserver-Script realisiert und ist frei im Internet verfügbar. / This contribution describes an automatic method, which can be applied to classical geodetic computation problems. Starting from given input quantities (e. g. coordinates of known points, measurements) computation opportunties for all other relevant quantities are found. For redundant input quantities a multitude of different computation opportunties exists, which are all found automatically, and their results are computed. If the computation is non-unique, but only a finite number of solutions exist, then all solutions are found and computed. By comparison of the different computation results there is the opportunity to detect gross errors in the input quantities and to produce a robust final result. The method does not work stochastically, so no stochastic model of the observations is required. The description of the algorithm is illustrated with the help of examples. The method was implemented as a webserver script and is available for free in the internet.

No caso da experiência brasileira, o desenvolvimento do Terciário no contexto da recente reestruturação econômica teve participação importante. Na década de 1990 a economia nacional foi palco de grandes transformações, nas quais alguns serviços reestruturados e/ou "modernizados" e mais dinâmicos permitiram maior agilidade econômica. O reordenamento da economia nacional e as novas formas de inter-relacionamento setorial vêm exercendo efeitos sobre a localização de muitas atividades econômicas, abrindo novas janelas de oportunidade. Temia-se que essas transformações levassem à "desindustrialização" e uma concentração do PIB e das ocupações nas macro-regiões e nos estados mais desenvolvidos (notadamente os que apresentam as maiores estruturas industriais). Mas a análise dos dados sobre o crescimento do PIB no Brasil nos leva a crer numa forte interdependência dos serviços com o desempenho da Indústria e da Agricultura. Não há elementos suficientes para afirmar que tenha havido uma autonomização apontando um rearranjo no qual o Terciário passe a ditar a dinâmica do desenvolvimento econômico. A evolução das ocupações mostra um crescimento maior justamente de serviços distributivos e produtivos, fortemente influenciados pelas atividades produtivas industriais e agroindustriais. Mesmo que se trate de uma estratégia de redução de custos frente à elevada tributação da folha de pagamento, isso não afasta as evidências de que a sinergia de determinados serviços com outros setores da economia não tenha aumentado consideravelmente nas duas últimas décadas. Quanto à concentração regional foi possível constatar uma redistribuição do PIB (IBGE) e das ocupações (PNAD/IBGE) em direção das macrorregiões periféricas. O papel dos setores recentemente reestruturados do Terciário nacional nesse processo é o objeto de estudo dessa tese. Esses setores fortaleceram seu poder de influir no desenvolvimento econômico setorial e regional do Brasil. Mas mesmo esses setores tendo aumentado sua contribuição ao crescimento do PIB do Brasil, este aumento foi pequeno perto do aumento das ocupações (PNAD) nos grupos de apoio a produção a que pertencem (serviços distributivos e serviços produtivos) e o aumento das ocupações nos setores tradicionais foi muito elevado (serviços coletivos e serviços pessoais). / Abstract: The following thesis discusses some issues on the role played by some specific kinds of services in economic development. Within Brazilian experience, the Tertiary Sector development was very significant in the context of recent economic restructuring. Through the 1990's Brazilian national economy was a scenario of great transformation in which a few restructured and / or modernized, more dynamic services made room for greater economic agility. National economy's rearrangement and the new features of economic sectors inter-relations have been causing impacts on economic activity location and presenting new opportunities. One feared these transformations would cause "de-industrialization" and GDP and occupational concentration on more developed macro-regions and states (especially within those which hold the biggest industrial structures). But analysis on Brazilian GDP growth data leads to the finding of great service interdependency regarding Industry and Agriculture economic performances. There are no sufficient elements to support the theoretical point of view that there has been a tertiary self-determination, a change towards an economic arrangement in which the Services Sector would guide the dynamics of economic development. Labor market behavior shows a higher occupational growth precisely on productive and distributive services, which are strongly influenced by industrial and agri-industrial productive activities. Even when that kind of behavior is guided by a firm strategy of cost reduction - due to high payroll taxation - it does not erase strong evidence of increasing synergy between certain services and other economic activity sectors in the two last decades. As to regional concentration of economic activities, it has been possible to identify redistribution of GDP (IBGE data) and occupations (PNAD-IBGE data) towards peripheral macro-regions. The role of recently restructured activities of the national Tertiary Sector within that process of change is the aim of this thesis. These activities have strengthened their power of influence on Brazilian sector and regional economic development. Despite having an increased in Brazilian GDP growth, these tertiary activities are more significant when it comes to their higher labor increased (PNAD-IBGE data), i.e., the volume of occupations provided by production-support service activities (distributive and production services); and the increase of occupations in the traditional sectors was high to (collective and social services). / Doutorado / Economia Social e do Trabalho / Doutor em Desenvolvimento Economico

The density amplitude of an isolated quantum vortex line in superfluid 4He is calculated using a generalized Gross-Pitaevskii (G-P) equation. The generalized G-P equation for the order parameter extends the usual mean-field approach by replacing the interatomic potential in the ordinary G-P equation by a local, static T matrix, which takes correlations between the particles into account. The T matrix is a sum of ladder diagrams appearing in a diagrammatic expansion of the mean field term in an exact equation for the order parameter. It is an effective interaction which is much softer than the realistic interatomic Morse dipole-dipole potential from which it is calculated. A numerical solution of the generalized G-P equation is required since it is a nonlinear integro-differential equation with infinite limits. For the energy denominator in the T matrix equation, a free-particle spectrum and the observed phonon-roton spectrum are each used. For the fraction of particles in the zero-momentum state (Bose-Einstein dondensate) which enters the equation, both a theoretical value of 0.1 and an experimental value of 0.024 are used. The chemical potential is adjusted so that the density as a function of distance from the vortex core approaches the bulk density asymptotically. Solutions of the generalized G-P equation are not very dependent on the choice of energy denominator or condensate fraction. The density profile is a monotonically increasing function of the distance from the vortex core. The core radius, defined to be the distance to half the bulk density, varies from 3.7 A to 4.7 A, which is over three times the experimental value of 1.14 A at absolute zero.

This thesis attempts to measure the growth of the Bolivian informal sector. The study estimates the growth of the informal sector by defining it as the difference between the formal sector's reported real gross national product (GNP) and forecasted values of real GNP. The first chapter describes the Bolivian economy, defines its informal sector, and presents reasons for this sector's growth. Related research in informal activity, theoretical discussions, and perspectives are presented in the second chapter. Chapter III describes methodological research used in the analysis of the data. Chapter IV describes the results of the investigation. Conclusions and recommendations for the informal sector are provided in chapter V. The results show that it is possible to measure informal activity in a macro setting

The role of energy in wealth and development is evident but the manner that a population’s access to energy effects overall growth is unclear. Understanding the role of energy in society can impact policies to push improvement in underdeveloped countries. Therefore, it is necessary to know how energy improves quality of life and what improvements need to be made to provide the necessary resources to underdeveloped populations. The first half of the thesis focuses on the role of energy use in society and its effect on human development. It is established that underdeveloped countries are in fact positively affected from increased energy access. Additionally, that the use of renewables will improve all the aspects of human development: health, wealth, and education. These results suggest that policy makers should focus on increasing clean energy in developing countries to also improve overall development. The second half shifts to the design and characterization of a water tunnel and the role it has in understanding fluid flow for near-wall visualization. Using refractive index matching (RIM) this experimental method can be used to study micro-surfaces that could improve efficiency in transportation or renewable energy. The water tunnel herein can achieve turbulent flows, unlike previous RIM designs.

traders are perceived to extract monopoly rents from farmers by offering very low prices. However, little attempt has been made to understand the behaviour of private traders and the factors that influence their behaviour. This study, therefore, examines the behaviour of private traders and determines the factors influencing their behaviour by means of the Chi-squared test. It further identifies the characteristics of smallholder farmers and private traders transacting with each other and examines the pricing, grading and weighting systems used by private traders, as well as the relationship that exists between farmers and private traders. Understanding private trader behaviour, factors influencing this behaviour, and the relationship between farmers and these private traders are important questions and have great implications for policy. Primary data was used in this study which involved interviews and direct observations with both private traders and smallholder farmers. The sample sizes for private traders and smallholder farmers were 50 and 200, respectively. The data was collected in the Kalomo District of Zambia between June and August, 2015. Only those farmers that transact with private traders or use assembly traders as the marketing channel were included in this study. The data collected was analysed using gross marketing margin, the Chi-squared test and descriptive statistics. The measure of the extent of opportunistic behaviour was also used to achieve the study objectives. The findings show that the mean price paid by private traders was ZMW 0.989 (USD 0.13) per kg and private traders were the ones who determine the prices and grades of maize. The private traders also weigh the maize and the smallholder farmers have little control on the final weight of the maize, as they do not participate in the weighing. This indicates that the private traders have power in the determination of the weight of maize. The majority of the private traders were found to behave opportunistically, accounting for 58 % of the surveyed traders. Experience and education level of the private traders were found to influence their behaviour. Given the importance of the above factors in influencing private trader behaviour, particularly experience and education, the results suggest that monitoring of the maize trading could potentially significantly reduce opportunistic behaviour among these less-experienced and less-educated traders. Lastly, the study reveals that 68.5 % of the smallholder farmers did not trust the private traders, whereas 46 % of the private traders did trust the farmers. The findings of this study indicate great potential for public sector investments in organisations that ensure standard weights (such as the Zambia Weights and Measures Agency 'ZWMA') and grades for maize. The ZWMA is the Zambian organisation responsible for enforcing weight institutions. An agency enforcing grading institutions for the smallholder maize farmers, however, does not exist in Zambia. Investment in such organisations would increase the levels of trust between farmers and traders, as neither would be suspicious of the weight or grade obtained, and possible opportunistic behaviour would be reduced. The suggestions and recommendations given by this study should help reduce the possibilities for opportunistic behaviour and exploitation of smallholder farmers. Because this study is in line with Zambia's poverty reduction plan to reduce poverty levels through increased agricultural production and improved maize trading among smallholder farmers, the recommendations given will help improve maize trading and the livelihoods of smallholder farmers. This is because they will be able to sell their maize at higher prices owing to reduced opportunistic behaviour of private traders, thus realising profits. The development of a grading system will lead to a better trading environment for both smallholder farmers and private traders, as both parties will be certain of the maize quality. In conclusion, a trading environment where organisations and institutions are in place, monitored and enforced to ensure reliable grading and weighing systems will help improve maize trading by smallholder farmers and private traders in Zambia. The improved maize trading will be the result of reduced opportunistic behaviour. This will ultimately increase the welfare of smallholder farmers and improve their livelihoods, which will contribute towards the reduction of the poverty levels in Zambia. / Dissertation (MSc (Agric))--University of Pretoria, 2016. / Agricultural Economics, Extension and Rural Development / MSc (Agric) / Unrestricted

Thesis (MTech (Business Administration))--Cape Peninsula University of Technology, 2018. / The purpose of this study was to determine the influence of internal controls on sustainability of small and medium enterprises (SMEs) in Harare’s Central Business District (CBD), Zimbabwe. The question at the core of this research is: to what extent do internal controls influence the sustainability of SMEs in Harare’s Central Business District, Zimbabwe. SMEs are perceived to be of paramount importance for the economic affluence of countries the world over, mainly because of their pronounced benefaction and contribution to livelihoods of the dwellers of a country and the gross domestic product (GDP). SMEs have been credited for playing a leading role when it comes to innovation, significant export revenue, custom-suited goods, services provision to society, employment opportunities, and social contribution. This can also be attributed to SMEs operating in Zimbabwe despite the volatility of the Zimbabwean economy. The Zimbabwean business environment, in general, is constantly changing. The changes can be attributed to an eruptive economic environment and unstable political atmosphere. The resultant effect is the departure of larger businesses and investors from the country. Generally, this leaves a great opportunity for SMEs not to be subjected to stiff competition from larger businesses. SMEs are indeed enjoying this space, braving the conditions to start up; however, their operations are short-lived. For SMEs to brave the fortuity of such an unpredictable environment, a system of internal controls must be in place. Research has placed emphasis on internal controls and sustainability of large organisations, while little to no attention has been given to SMEs. The little research on internal controls and sustainability in the context of SMEs has mostly been done in developed countries. Despite this, internal controls and sustainability have not been extensively implemented in the context of developing countries. The need to determine the influence of internal controls on sustainability of SMEs underlines this research. This report adopted a positivist philosophy that entailed utilizing a survey questionnaire to collect data from 150 SMEs operating in Harare’s CBD, Zimbabwe. The sample was further split into Active SMEs and Dormant SMEs (the control group). Data were analysed through Statistical Package for the Social Sciences (SPSS) Version 25 to spawn statistical and descriptive results. To determine reliability of data, Cronbach’s alpha value was employed. The results indicate SMEs are not implementing controls as they ought to and those SMEs that have controls in place do not ensure that they are adhered to effectively and efficiently in order for them to achieve their desired objectives.
