Investigation of completion Rates of Engineering students
No full textThe 2002 first year engineering cohort completion rates were investigated to the end of 2006. About 20% of these students actually graduated from engineering during this time and approximately 60% had discontinued the course altogether. A support program (QUTMAC) is run along side the mathematics units in the first year. Students who used this service were twice as likely to complete their course compared to those who did not
Measuring and analyzing German and Spanish customer satisfaction of using the iPhone 4S Mobile Cloud service
Full text linkThis paper presents the customer satisfaction analysis for measuring popularity in the Mobile Cloud, which is an emerging area in the Cloud and Big Data Computing. Organizational Sustainability Modeling (OSM) is the proposed method used in this research. The twelve-month of German and Spanish consumer data are used for the analysis to investigate the return and risk status associated with the ratings of customer satisfaction in the iPhone 4S Mobile Cloud services. Results show that there is a decline in the satisfaction ratings in Germany and Spain due to economic downturn and competitions in the market, which support our hypothesis. Key outputs have been explained and they confirm that all analysis and interpretations fulfill the criteria for OSM. The use of statistical and visualization method proposed by OSM can expose unexploited data and allows the stakeholders to understand the status of return and risk of their Cloud strategies easier than the use of other data analysis
Necrológio de Victor Giudice: artimanhas ficcionais em tempos ditatoriais
Full text linkTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em Literatura.A presente tese tem como objetivo abordar as narrativas de Necrológio, obra inaugural de Victor Giudice, publicada em 1972, em sua relação com o período ditatorial brasileiro. Assim como outros artistas do contexto, o escritor se utiliza de estratégias para driblar a censura da ditadura militar. Com Necrológio, Giudice assume o papel de artífice de sua própria época através da carnavalização da temática da morte, uma protagonista da qual seus personagens se tornam simulacros. Através do fantástico e da metamorfose, o autor expõe personagens que são inquilinos de um universo desumanizado.The present thesis aims to approach Necrológio, Victor Giudice's inaugural book published in 1972, in its relations to Brazilian dictatorship. Victor Giudice, as many other artists in that context, uses strategies to trick censorship in the dictatorial period. With Necrológio, Giudice takes the role of artificer of his own time through the carnavalization of the thematic of death, the main protagonist of his book to which his characters function as simulacra. Through the fantastic and the matamorphosis, the author exposes characters that inhabit a deshumanized universe
An Introductory Approach to Risk Visualization as a Service
Full text linkThis paper introduces the Risk Visualization as a Service (RVaaS) and presents the motivation, rationale, methodology, Cloud APIs used, operations and examples of using RVaaS. Risks can be calculated within seconds and presented in the form of Visualization to ensure that unexploited areas are ex-posed. RVaaS operates in two phases. The first phase includes the risk modeling in Black Scholes Model (BSM), creating 3D Visualization and Analysis. The second phase consists of calculating key derivatives such as Delta and Theta for financial modeling. Risks presented in visualization allow the potential investors and stakeholders to keep track of the status of risk with regard to time, prices and volatility. Our approach can improve accuracy and performance. Results in experiments show that RVaaS can perform up to 500,000 simulations and complete all simulations within 24 seconds for time steps of up to 50. We also introduce financial stock market analysis (FSMA) that can fully blend with RVaaS and demonstrate two examples that can help investors make better decision based on the pricing and market volatility information. RVaaS provides a structured way to deploy low cost, high quality risk assessment and support real-time calculations
Current preferences of Southern Mediterranean Countries and their erosion after variations of the entry price system
Full text linkIt has been calculated the value of the preference margin granted to Euro-Mediterranean partners in the cases of reduced entry prices in force, and then it has been simulated the impact of EU trade liberalisation for F&V on such values after two different alternatives of EP system variations resulting from a WTO agreement. The results of current preferences indicate that in monetary terms there is only a significant relevance of the preferential EPs in the case of Moroccan tomatoes and, to a lesser extent, in Moroccan clementines. Very little is the relevance for Jordanian tomatoes and cucumbers and Moroccan courgettes, cucumbers and artichokes. In the cases of oranges from Egypt, Morocco, Israel and Jordan, preferential EP has not meant potential monetary transfers to these preference-receiver countries. Instead, the ad valorem tariff exoneration seems crucial in almost all the products. With regard to the erosion of preferences as a result of a WTO agreement, the magnitude of the erosion depends crucially on the variation/no-variation of the current trigger EPs, and the undermining of preferences is concentrated mostly on Moroccan tomatoes.Entry prices, erosion of trade preferences, Euro-Mediterranean trade, fruits and vegetables, International Relations/Trade,
On Monetary Policy, Unemployment, and Economic Growth
Full text linkRecognizing the possible relation between investments, economic growth and unemployment, and how there is not an established impact of an unlikely productive project failure on the secondly mentioned variables, we address such relation and asses theoretically the effect of different instruments of monetary policy on the mentioned macroeconomic indicators. To do this we modify two models of economic growth by considering the role of entrepreneurs, risk takers, and a monetary authority which is the average agent of the economy that is assumed to be aware of how the inflation can damage equally the individuals' life style, independently of their particular levels of income, finding that the impact of the monetary instruments depends on the behavior of the population
Emptiness Existence: A Free-Strategic view
Full text linkWe formulate a theorem on the emptiness existence followed by its matematicall proof, that takes as a base a single axiom named hipoteticity i.e. an element exists iff it has a structure
On Behavioral Macroeconomics, Globalization, and Economic Growth
Full text linkWe assess theoretically the effect of forming a free trade union on the total production of a nation, where such effects are caused by the absorption of technologies. A popular metaphor describes the people as crabs in a bucket because when one crab tries to scape, the others pull it down avoiding a possible way out for all of them. Given this knowledge, posteriorly and independently of the income inequality levels, we extend our analyses to consider the effect of envy in a macroeconomic level on the total production, and draw the implications which this phenomenon has on the formation of free trade unions. We make strategic policy recommendations to allow the achievement of a globalization that benefits each member nation, where we show that the great trade union might have to start with gradual and charitable subregional agreements
Towards a Democratization of Knowledge with Topological Emphasis in Economics
Full text linkWe formulate and prove a theorem which consists in how the natural endogenous antagonist interaction of agents who look for understanding a generalizable phenomenon, results in a tendency towards chaos. This takes us to the final absolution of implementing the majority rule as the only instrument that generates socially acceptable knowledge, escaping from the chaos tendency. Finally, we extend our analysis to consider the arise of multiple simultaneous antagonist postures on the explanation of a phenomenon, and through an application of the Pythagoras theorem, we prove that it takes less effort or sacrifice for an agent to learn strategically to get an explanation, than if she was the creator of the concerning knowledge, which implies different consequences of possible topological private and public tendencies
Expectations Over Durable Assets: How to Avoid the Formation of Value Bubbles.
Full text linkThere is a finite set of characteristics which can be present in a durable asset adding value to it, and that are not necessarily part of it in the moment of its adquisition. We represent formally how the expectations over the possible future characteristics of these goods influence its price, and get the conditions for the formation of bubbles, which allows us to propose mechanisms to avoid this kind of instinctive collective regimes. Posteriorly we extend our analysis to consider the case of monopoly and of an m-firms oligopoly producing these kinds of goods, finding that the cardinality of the firm(s)' possible plans of production to maximize benefits is the same. We show relation between the assets' prices and the cardinalities of the sets of suppliers, assets' varieties and entry consumers, with an indirect dependence on the rentlabor wages. We model boundedly an analysis of the effect of tendencies like corruption on newly informed and non-bayesian probabilities that constitute the prices. Finally, some extra provided mechanisms to avoid bubbles focus in reverting badly programed rule of thumbs, to get back to the rightgreat rules respec
