Putting theory to work: the use of theory in construction research

Attention to epistemology, theory use and citation practices are all issues which distinguish academic disciplines from other ways of knowing. Examples from construction research are used to outline and reflect on these issues. In doing so, the discussion provides an introduction to some key issues in social research as well as a reflection on the current state of construction research as a field. More specifically, differences between positivist and interpretivist epistemologies, the role of theory in each and their use by construction researchers are discussed. Philosophical differences are illustrated by appeal to two published construction research articles by Reichstein et al. and Harty on innovation (Reichstein, Salter and Gann, 2005; Harty, 2008). An analysis of citations for each highlights different cumulativity strategies. The potential contribution of mixed research programmes, combining positivist and interpretivist research, is evaluated. The paper should be of interest to early researchers and to scholars concerned with the ongoing development of construction research as an academic field.

A web based decision support system for status assessment in advanced parkinson

The purpose of this work is to develop a web based decision support system, based onfuzzy logic, to assess the motor state of Parkinson patients on their performance in onscreenmotor tests in a test battery on a hand computer. A set of well defined rules, basedon an expert’s knowledge, were made to diagnose the current state of the patient. At theend of a period, an overall score is calculated which represents the overall state of thepatient during the period. Acceptability of the rules is based on the absolute differencebetween patient’s own assessment of his condition and the diagnosed state. Anyinconsistency can be tracked by highlighted as an alert in the system. Graphicalpresentation of data aims at enhanced analysis of patient’s state and performancemonitoring by the clinic staff. In general, the system is beneficial for the clinic staff,patients, project managers and researchers.

Rollbaserad åtkomstkontroll med geografisk avgränsning : En systematisk litteraturgenomgång av det befintliga kunskapstillståndet inom ämnesområdet

Rollbaserad åtkomstkontroll är en standardiserad och väl etablerad modell för att hantera åtkomsträttigheter i informationssystem. Den vedertagna ANSI-standarden 359-2004 saknar dock stöd för att geografiskt avgränsa rollbehörigheter. Informationssystem som behandlar geografiska data och de senaste årens ökade spridning av mobila enheter påkallar ett behov av att sådana rumsliga aspekter diskuteras inom kontexten av rollbaserad åtkomstkontroll. Arbetet syftar till att bringa klarhet i hur det befintliga kunskapstillståndet inom ämnesområdet rollbaserad åtkomst kontroll med geografisk avgränsning ser ut, och vilka aspekter hos detta som står i behov av vidare utveckling. Genom de teoretiska referensramar som skapats vid inledande litteraturstudier har en efterföljande systematisk litteraturgenomgång möjliggjorts, där vetenskapligt material selekterats genom fördefinierade urvalskriterier. Sammanställningen och analysen av den systematiska litteraturgenomgångens resultat har i samverkan med de teoretiska referensramarna lett fram till arbetets huvudsakliga kunskapsbidrag: en områdesöversikt där ämnets state-of-the-art presenteras och en strukturerad lista över angelägna forsknings- och utvecklingsbehov inom området.

Humorforskning i svenska organisationer och arbetslivssammanhang : en litteraturöversikt

Research on humor in Swedish organizational and working life contexts: a literature review The objective of this study was to provide a more coherent picture of research on humor in Swedish organizational and working life contexts, where even non-strictly organizational studies were included due to their high relevance in the research area. A systematic review of the literature published during the last 15 years was used to summarize an obviously undeveloped research area in Sweden. Published peer-reviewed articles that primarily examine humor were analyzed. Seventeen representative articles have been found and systematically reviewed and compared focusing on four questions: purposes and contexts of the studies, theoretical approaches, methods and main results. The analysis identifies four focal points that describe current state of humor research in Sweden: 1) positive function of humor appears to be a predominant research issue while humor’s subversive function, power relations and negative functions are less represented, 2) limited comparative studies of different contexts 3) biased theoretical approaches and limited studies of theory developing approach 4) overrepresented qualitative research approach. The above issues were discussed in relation to relevant international humor research.

A generalization of judds method of out-steady-state comparisons in perfect foresight models

We show that Judd (1982)’s method can be applied to any finite system, contrary to what he claimed in 1987. An example shows how to employ the technic to study monetary models in presence of capital accumulation.

Fiscal multipliers in an incomplete markets economy

This paper studies the behavior of fiscal multipliers in two different economic environments: complete markets and incomplete markets. Based on steady state analysis, output multipliers are found within a range between 0.49 and 0.66, when the markets are complete. Under incomplete markets, output multiplier was found in an interval between 0.75 and 0.94. These results indicates that the market structure, which reflects the degree of risk sharing and the intensity of the precautionary motive faced by individuals, plays a key role in determining the fiscal multipliers. In the second part of the paper, was performed an exercise to analyze the dynamic response of macroeconomic aggregates to an exogenous and unexpected rise in government spending financed by lump-sum taxes. In this case, impact output multipliers varies in a range between 0.64 and 0.68, under complete markets, and within 1.05 and 1.20 when markets are incomplete. The results found under incomplete markets are very close to that found on related literature which usually uses an econometric approach or calibrated/estimated New Keynesian models. These results shows that taking into account the deficiencies in the insurance mechanisms can be an interesting way to reconcile theoretical models with the results found on related current literature, without the need of ad-hoc assumptions relative to price stickness.

Transparência no governo do Estado do Rio de Janeiro: análise e recomendações

O presente trabalho apresenta um diagnóstico e uma análise da transparência no governo do estado do Rio de Janeiro. Desde a sanção da Lei de Acesso a Informações – LAI no Brasil, lei n° 12.527/2011, e as regulamentações dos governos subnacionais, o estado do Rio de Janeiro tem sido avaliado negativamente por instituições de ensino e pesquisa e por metodologias desenvolvidas pelo próprio governo federal, no sentido principal de garantir o direito fundamental de acesso à informação. Para caracterizar a situação do Rio de Janeiro, foi realizada uma análise da transparência sob quatro dimensões: (i) legal; (ii) tecnológica; (iii) organizacional; e (iv) política. Disto, decorre o desafio que conduz o presente trabalho, que é o de aperfeiçoar a transparência fluminense, mediante a sistematização de diretrizes com recomendações de melhoria, a partir das normas vigentes, das boas práticas no setor público e das inadequações do governo fluminense, também apontando os benefícios específicos que as medidas concretas podem gerar. Ao final, são sugeridos passos para melhorar o compromisso do estado com a transparência pública.

Fatores de decisão da adoção do gás natural na geração de energia elétrica em pequena escala em postos de combustíveis: um estudo de anális de decusão usando o processo de hierarquia analítica AHP

A modeling of criterias and alternatives is through and applied a questionnaire based on method AHP to proprietors of gas stations. The considered alternatives had been the maintenance of the current state with electric energy of the deliverer and the generation in small scale based on the natural gas. The used criteria had been Cost of the Investment, Final Cost of the Energy, Operational cost, Ambient Benefits, Risk and Variation of Costs. The study it was carried through in the city of Natal, RN in ranks that make use of the natural as for resale, where the generation alternative on the basis of the available gas is present. The main results evidence in a dimension the viability of use of method AHP with questionnaire by means of validation of the judgments with analysis of variance beyond proper the normal mechanisms of analysis of consistency to the method. The main results of the analysis help to show that in this in case that the profile of models of criteria and judgments of the actors is similar, with the final evidence of that it has a dominance of the maintenance of the energy of the deliverer. The main criterion to influence this decision was the risk

Uma aplicação de análise de decisão com o método AHP Processo de hierarquia analítica: um estudo sobre adoção de Sistema eletrônico de cobrança no Transporte público urbano

This thesis carries through an application of Analysis of Multicriterion Decision with use of the method of Analytical Hierarchy Process (AHP) in the problematic one of taking of decision of the adoption of electronic collecting in the system of urban transport in the country, a subject that has been controversial. A modeling of criteria and alternatives is carried through and applied a questionnaire based on method AHP the excellent actors in the system of urban transport - Leading of the Managing Agency Public Municipal theatre of Urban Transports, Controller of Company of Bus, Controller of Labor union, Controller of Union of Companies, Communitarian Leader. The considered alternatives were: the maintenance of the current state with collectors, the implementation of electronic collection without collectors, and the implementation of electronic collection with collectors. The used criteria were: job, impact in the fare, control of the system, easiness of use, information. The study was carried through in the city of Natal, RN, where if the adoption of electronic collection argues and where this implementation in some bus lines between Natal and Parnamirim exists, city that integrates the region of the great Natal. The main results of the method evidence in a dimension, the viability of use of method AHP with questionnaire by means of validation of the judgments with analysis of variance beyond proper the normal mechanisms of analysis of consistency to the method, and in another one, the contribution of the analysis boarding multicriterion to become the judgments more clearly. The main results of the analysis help to show that although to models of criteria and distinct judgments of the actors, the method evidenced that it has inclination the adoption of the electronic collection on the current situation, even so with divergences between the maintenance or not of the collector. The research points to the possibility of accomplishment of the application of the AHP in successive rounds of judgments

Da polêmica sobre a pós-modernidade aos 'desafios' lyotardianos à Filosofia da Educação

As relações entre pós-modernidade e educação tem sido objeto de inúmeras pesquisas, bem como de certa polêmica no âmbito da Filosofia da Educação, a começar pela própria conceituação da pós-modernidade até chegar às posições filosóficas engendradas por ela. em quase todas essas pesquisas e polêmicas, A condição pós-moderna, de Jean François Lyotard, se configura como uma referência importante, porém raramente as obras subseqüentes a essa são mencionadas, deixando uma parte de seu legado filosófico de fora de tais discussões e, particularmente, de suas eventuais contribuições para a educação. Tendo em vista esse limiar dos estudos sobre o assunto, o presente artigo procura desenvolver uma interpretação acerca do pensamento lyotardiano, privilegiando a análise das obras subseqüentes ao seu livro mais polêmico, com o objetivo de situar o seu projeto filosófico para além de um marco da pós-modernidade e de discutir as suas contribuições à Filosofia da Educação na atualidade. Mediante tal interpretação, recupera-se um projeto filosófico que lança alguns 'desafios' à Filosofia da Educação referentes ao deslocamento de sua problemática epistemológica para a estética, nutrida por um pensamento capaz de elucidar a face complexa e obscura da educação, a sua sombra inumana, e o diferendo constitutivo do ensino, inapreensíveis pela linguagem e pela comunicação. Assim, esperamos que tal projeto possa ser compreendido não por aquilo que traz de polêmico à Filosofia da Educação, mas pelo que a desafia no tempo presente, como uma reescrita da modernidade.

Determination of the geographical origin of Brazilian wines by isotope and mineral analysis

In the present research, we studied wines from three different south Brazilian winemaking regions with the purpose of differentiating them by geographical origin of the grapes. Brazil's wide territory and climate diversity allow grape cultivation and winemaking in many regions of different and unique characteristics. The wine grape cultivation for winemaking concentrates in the South Region, mainly in the Serra GaA(0)cha, the mountain area of the state of Rio Grande do Sul, which is responsible for 90% of the domestic wine production. However, in recent years, two new production regions have developed: the Campanha, the plains to the south and the Serra do Sudeste, the hills to the southeast of the state. Analysis of isotopic ratios of (18)O/(16)O of wine water, (13)C/(12)C of ethanol, and of minerals were used to characterize wines from different regions. The isotope analysis of delta(18)O of wine water and minerals Mg and Rb were the most efficient to differentiate the regions. By using isotope and mineral analysis, and discrimination analysis, it was possible to classify the wines from south Brazil.
