Czech Study of Public Policy in the Perspective of Three Dominant Approaches
Authors: Novotný Vilém
Published: February 2016

The Velvet Revolution in 1989 did not represent only a fundamental change of the political regime, but also the beginnings of contemporary Czech study of public policy and policy expertise. This article aims to present its significant institutional aspects on the basis of a systematic analysis drawing on deLeon, Trent and Stein’s models of (sub)discipline development. It assumes that the development of a field of study is driven by the interaction between its inner dynamics and the surrounding environment (society, state and international academic community). The article identifies three dominant approaches in the configuration of the Czech field - Prague public policy, Brno political science and Brno social policy - and it focuses on their supporting infrastructure, frames of reference and contacts with the international academic community. Finally, it outlines the study’s development stages, revealing that Czech study of public has been quickly catching up with its Western counterparts.
Public Policy Programmes and Policy Analysis Instruction in the Czech Republic
Authors: Veselý Arnošt , Zelinková Anna
Published: February 2016

The aim of the paper is to provide the first systematic review of instruction in public policy programmes (PPP) in the Czech Republic and examine the role and nature of policy analysis therein. First, the Czech higher education system is briefly described. Second, an overview of PPP in the Czech Republic is provided. This analysis is based upon a publicly available list of degree programmes accredited by the Ministry of Education, Youth and Sports, an internet search, e-mail correspondence with public policy and policy analysis instructors, and syllabuses. It is shown that while a diverse set approaches is used, the classical “positivist” perspective is clearly dominant. Third, using survey data (N = 192) we analyse the views of Public and Social Policy graduates on the importance of competences in practice and the quality of actually learnt competences. Last, preliminary conclusions on public policy/policy analysis instruction in the Czech Republic are discussed. It is shown that public policy instruction is rather fragmented and is institutionalized under different disciplines. The respondents were most satisfied with gaining skills in the areas of policy analysis, ability to orient oneself and acquire new knowledge, and strategic and analytical thinking. In contrast, they were least satisfied with acquiring organizational skills, practical professional experience and skills, and computer literacy.
Radiated Information Infiltration Channel Concerning Programme Based Solutions for Information Protection Prior to its Non-Invasive Acquisition
Authors: Kubiak Ireneusz
Published: February 2016

The methods for protection of non-public information against electromagnetic infiltration are very important issue that requires constant development of technological advancement of the devices on which such information is processed. The current methods are the solutions regarding construction of the devices and organisation oriented solutions that are related mainly to physically limiting access to such information. The new area concerning electromagnetic protection of processed information by means of electricity is the programme based methods. These, however, do not deal with the issues of cryptographic information protection. The programme based protection uses special shapes of fonts, which having passed through the Radiated Information Infiltration Channel (RIIC) make reading of protected data impossible. This is achieved through eliminating specific character elements (roots, sheriffs, arcs) and maximising the degree of similarity between them. However, the assimilation should not make the original characters, i.e. those displayed on the screen of the device that processes these data harder to differentiate between them.

Yet, is maximising the degree of similarity between the characters of a safe font decisive for electromagnetic security?

The article presents two font solutions of similar character shape, which are however much different from one another in terms of their degree of recognisability on the output of the RIIC due to structural detail. This shows that maximising similarity between characters in their original form does not have to increase the degree of resistance to recognition of the secondary characters.
Failure Issues in WiFi Networks Applied in Intelligent Home Systems
Authors: Lech Piotr , Purczyński Jan , Kornatowski Eugeniusz , Włodarski Przemysław
Published: February 2016

This article presents current research on failure issues in the IEEE 802.11g wireless network that can be easily applied in the intelligent home system. Different systems in different communication models coexisted with each other in the same time of operation. As a result of many observations the new statistical model of communication system failures was developed. During normal operation there should be no connection loss in the ideal case. However, when transmitting devices are located on the edge of the wireless network range, the connection could be lost. The problem of reconnections cannot be ignored in the process of automation devices control, especially when dealing with sensitive data transmitted using e.g. Internet of Things technologies. One of the possible scenarios that could take place after link failure is the stability loss of the system or issues with data integrity. All research presented in this work could help in performing new computer simulations, and as a consequence - by appropriate designing of queueing systems - preventing data loss.

Ray-Tracing-Based Event Detection and 3D Visualization for Automated Video Surveillance System
Authors: Przybyło Jaromir , Jabłoński Mirosław
Published: February 2016

Automated and intelligent video surveillance systems play important role in current home care and facilities security applications. Among many research problems is graphical visualization of semantic messages to the human operator that he can percept information in more natural way. The other essential research question is how to recognize 3D objects and their state on the monitored scene only from their views (2D images from the camera). In this paper we continue our previous work on data fusion in visualization of 3D scene semantic model and propose to recognize events and states of scene objects under surveillance in an automatic way using feedback provided by the renderer. We developed ray-tracing based visualization for surveillance system, that is capable of recognizing object’s state and at the same time present relevant information to the human operator.
‘Set Adrift’: Fatalism as Organizational Culture at Canadian Seaports
Authors: Quigley Kevin F. , Mills Bryan
Published: February 2016

This paper takes an anthropological approach to understanding the governance of seaport security in Canada; it uses cultural theory and the concepts of regulation and integration as key determinants in understanding how organizations respond to risk. This paper draws on data from 29 semi-structured interviews with transportation specialists, including owners, operators, managers and regulators. Nine of the interview subjects came from seaports, in particular. The interviews occurred between 2011 and 2013. We argue that Canadian seaports exist in an area of confusing multi-level governance; they are immovable, are expected to be competitive and serve a number of (at times competing) public and private sector interests. These institutional arrangements have resulted in a security environment that is heavily regulated, but the community itself is not well integrated. Interview subjects raise concerns about the ports’ ability to respond to security threats. The paper then uses cultural theory to examine alternative governance arrangements enhancing, for example, community, competition or regulation. While most options to improve security will likely reduce the competitiveness of the seaports, it would help to instill more confidence among port staff and enhance organizational learning.
Beating the market betting on NHL hockey games
Authors: Buttrey Samuel E.
Published: February 2016

This article describes a method for predicting the outcome of National Hockey League (NHL) games. We combine a model for goal scoring and yielding, and one for penalty commission, in a Markov-type computation and a simulation model that produce predicted probabilities of victory for each team. Where these differ substantially from the market probabilities, we make “bets” according to a simple strategy. Our return on investment is both positive and statistically significant.
Is there a Pythagorean theorem for winning in tennis?
Authors: Kovalchik Stephanie Ann
Published: February 2016

Bill James’ discovery of a Pythagorean formula for win expectation in baseball has been a useful resource to analysts and coaches for over 30 years. Extensions of the Pythagorean model have been developed for all of the major professional team sports but none of the individual sports. The present paper attempts to address this gap by deriving a Pythagorean model for win production in tennis. Using performance data for the top 100 male singles players between 2004 and 2014, this study shows that, among the most commonly reported performance statistics, a model of break points won provides the closest approximation to the Pythagorean formula, explaining 85% of variation in season wins and having the lowest cross-validation prediction error among the models considered. The mid-season projections of the break point model had performance that was comparable to an expanded model that included eight other serve and return statistics as well as player ranking. A simple match prediction algorithm based on a break point model with the previous 9 months of match history had a prediction accuracy of 67% when applied to 2015 match outcomes, whether using the least-squares or Pythagorean power coefficient. By demonstrating the striking similarity between the Pythagorean formula for baseball wins and the break point model for match wins in tennis, this paper has identified a potentially simple yet powerful analytic tool with a wide range of potential uses for player performance evaluation and match forecasting.
The Role of Voluntary Organisations in Constructing the Common Identity and Mobilising of Polish Community in Southeastern Lithuania
Authors: Frėjutė-Rakauskienė Monika
Published: February 2016

This paper is based on a series of qualitative (semi-structured) interviews conducted by the author with representatives of Polish civic organisations in southeastern Lithuania (the towns of Eišiškės, Jašiūnai, Pabradė, Šalčininkai, Švenčionys, Švenčionėliai, and Turgeliai). Data was collected from January 2013 to June 2014 as part of a research project to investigate ethnic, civic, regional, and local identities of ethnic minorities in southeastern Lithuania. The project was carried out by the Institute for Ethnic Studies at the Lithuanian Social Research Centre and was funded by the Research Council of Lithuania. The paper discusses the role of voluntary organisations operating in Southeastern Lithuania in mobilising the Polish community. The author investigates the activity of Polish organisations as they maintain and construct the identity (ethnic, civic, local and regional) of local community. Part of the research strategy is to recognise the content and means by which these organisations appeal to collective memory to create and affirm Polish identity. An analysis of interview data shows that the activities of organisations predominantly target the Polish community and their aims are to promote and foster Polish culture, language, and history. The Polish civic and political organisations and their leaders play active roles in identity building and mobilising the Polish Community in southeastern Lithuania. Referencing and recalling collective memories of the Polish ethnic group is an important tool for building a collective identity that lack local and regional dimensions.
Parallel implementation of the cascade mass-conserving semi-Lagrangian transport scheme
Authors: Shashkin Vladimir V. , Tolstykh Mikhail A.
Published: February 2016

Modern atmospheric models for climate simulations require accurate and efficient, locally mass-conservative and monotonic numerical schemes for treating the transport of atmospheric constituents. One of the ways to design such schemes is Finite-Volume Semi-Lagrangian approach (FVSL). FVSL schemes are characterised by the computational efficiency advantage due to the possibility of using large time-steps and efficient treatment of multiple transported quantities (tracers). This article presents massively parallel and multi-tracer efficient version of the recently developed 3D cascade FVSL transport scheme. Using hybrid distributed-shared memory parallelism with 1D MPI domain decomposition in latitude and OpenMP computations for longitude loops allows to use efficiently up to 1600 computational cores. We hope this number will grow with the future growth of the number of shared memory cores per computational node. Multi-tracer optimisations of the scheme (mostly, developing multi-tracer efficient monotonic filter) allow to reduce the cost of transporting additional tracer to 18–23% of running the scheme with one tracer.
Numerical Simulations of Blast Loads from Near-Field Ground Explosions in Air
Authors: Dobrociński Stanisław , Flis Leszek
Published: February 2016

Numerical simulations of air blast loading in the near-field acting on the ground have been performed. A simplified blast model based on empirical blast loading data representing spherical and hemispherical explosive shapes has been simulated. Conwep is an implementation of the empirical blast models presented by Kingery and Bulmash, which is also implemented in the commercial code LS-DYNA based on work done by Rahnders-Pehrson and Bannister. This makes it possible to simulate blast loads acting on structures representing spherical and hemispherical explosive shapes of TNT with reasonable computational effort as an alternative to the SPH and Eulerian model. The CPU time for the simplified blast model is however considerably shorter and may still be useful in time consuming concept studies. Reasonable numerical results using reasonable model sizes can be achieved not only for modelling near-field explosions in air but most areas of geotechnical. Calculation was compared with blast SPH and Eulerian model.
Some Considerations on Horizontal Displacement and Horizontal Displacement Coefficient B
Authors: Tajduś Krzysztof , Tajduś Antoni
Published: February 2016

Mining-induced deformations of the ground surface and within the rock mass may pose danger not only for surface constructions but also for underground objects (e.g., tunnels, underground storages, garages), diverse types of pipelines, electric cables, etc. For a proper evaluation of hazard for surface and underground objects, such parameters as horizontal displacement and horizontal deformations, especially their maximum values, are of crucial importance. The paper is an attempt at a critical review of hitherto accomplished studies and state of the art of predicting horizontal displacement u, in particular the coefficient B, whose value allows determination of the value of maximum displacement if the value of maximum slope is known, or the value of maximum deformation if the value of maximum trough slope is recognized. Since the geodesic observations of fully developed subsidence troughs suggest that the value of the coefficient depends on the depth H, radius of main influences range r and properties of overburden rock, in particular the occurrence of sub-eras Paleogene and Neogene layers (old name: Quaternary and Tertiary) with low strength parameters, therefore a formula is provided in the present paper allowing for the estimation of the influence of those factors on the value of coefficient B.
Electrical Conduction in Transition-Metal Salts
Authors: Grado-Caffaro M.A. , Grado-Caffaro M.
Published: February 2016

We predict that a given transition-metal salt as, for example, a K2CuCl4·2H2O–type compound, can behave as an electrical conductor in the paramagnetic case. In fact, we determine the electrical conductance in a salt of this type. This conductance is found to be quantised in agreement with previous well-known results. Related mathematical expressions in the context of superexchange interaction are obtained. In addition, we determine the corresponding (macroscopically viewed) current density and the associated electron wave functions.
New Book Chronicle
Authors: Witcher Robert
Published: February 2016

With over half of the world's population living in cities, urbanism is one of the defining characteristics of the contemporary age. In the past, by contrast, most people lived scattered in villages and rural settlements. Yet pre-industrial cities still exerted a disproportionate influence on society, economy and culture. InCities that shaped the ancient world,John Julius Norwichcollects 40 of the most influential. Taking inspiration from this urban super league, this instalment of New Book Chronicle tackles a selection of new volumes, each concerned with one of the cities identified by Norwich, taking us 5000 years and 13 000 km from Ur to Tikal. Each book also presents a different publication format, offering the opportunity to think not only about the individual cities, but also how we write about them.

Published: February 2016

Primary intestinal lymphangiectasia (PIL), also known as Waldmann’s disease, is an exudative enteropathy resulting from morphologic abnormalities in the intestinal lymphatics. In this article, we describe a 12-year-old boy with PIL that led to protein-losing enteropathy characterized by diarrhea, hypoalbuminemia associated with edema (serum albumin level: 1.0 g/dL), and hypogammaglobulinemia (serum IgG level: 144 mg/dL). Severe hypoalbuminemia, electrolyte abnormalities, and tetany persisted despite a low-fat diet and propranolol. Everolimus (1.6 mg/m2/day) was added to his treatment as an antiangiogenic agent. With everolimus treatment, the patient’s diarrhea resolved and replacement therapy for hypoproteinemia was less frequent. Hematologic and scintigraphy findings also improved (serum albumin level: 2.5 g/dL). There were no adverse reactions during the 12-month follow-up. To the best of our knowledge, this is the first report of everolimus use in a patient with PIL.
SCOUR DURATION AT STRUCTURES AT STEADY FLOW CONDITIONS
Authors: LAUVA Oskars , GJUNSBURGS Boriss
Published: February 2016

One of the reasons of the bridge crossings failure or damage in flow is the unpredicted depth of scour near foundations. The aim of this study is to find the equilibrium time near elliptical guide banks. Analysis of the literature shows that there are no methods or formulas to calculate equilibrium time of scour near elliptical guide banks. In the formulas used in calculating equilibrium time at piers or abutments, different parameters are not taken into consideration. These parameters include: contraction rate of the flow, Froude number, bed layering, sediment movement parameters, local flow modification, ratio relative local and critical velocities, and relative depth. The differential equation of the bed sediment movement in clear water was used and method for computing equilibrium time of scour near elliptical guide banks was elaborated. New hydraulic threshold criterion is proposed for the calculation of equilibrium time of scour. Computer modeling results were compared with equilibrium time of scour which were calculated by the presented method and they were in agreement.
EXPERIMENTAL INVESTIGATION OF ENERGY CHARACTERISTICS OF EVACUATED TUBE HEAT-PIPE SOLAR COLLECTOR SYSTEM
Authors: KAVOLYNAS Antanas , DREJERIS Rolandas
Published: February 2016

Evacuated tube heat-pipe solar collector system with closed heat pipe has been experimentally investigated. Experiments have been fulfilled using the solar imitator whose energy irradiance on the surface of the solar collector at the constant ambient conditions is 800 W/m². Energy characteristics of the solar collector system with different flow-rates of the heat-transfer agent have been investigated using various flow-rate speeds of the heat-transfer agent. It has been stated that the increase of the flow-rate of the heat-transfer agent in the system from 0.01 to 0.12 kg/s would minimize the average collector efficiency from 0.81 to 0.55. When the reduced flow-rate of the heat-transfer agent has been used in the system, the higher temperature of the hot water is reached in the storage tank and at the same time the temperature of the heat-transfer agent in the system is increased. Thus, more energy has been lost in the pipeline and hot water storage tank, but less energy is used for the circulation of the heat-transfer agent energy. Increasing the agent flow-rate speed in the system has reduced the heat losses in the pipeline, but more energy is used for the energy circulation of the heat-transfer agent. Therefore, the medium efficiency of the solar collector system has changed insignificantly (0.47 ± 0.01).

Authors: KRUPIČKA Josef , ŠAŘEC Petr , NOVÁK Petr
Published: February 2016

Physical properties of commercial fertilizers play important role from precision application point of view. Granulometric evaluation is usually performed by sieve separation according ČSN 01 5030 standard. The main subject of this work is the presentation of separation results when vertical airflow is used with NPK 20-8-8 and Dolophos fertilizers. The sample was divided into 8 individual specimens of 0.5 kg weight that was measured repeatedly. Every class of the specimen was than sieved on the sieves with holes 2 mm, 3.5 mm, and 5 mm resulting four new subclasses characterized by the sieve mesh dimension. It was achieved by statistical evaluation that relative frequencies are in agreement with N-distribution. It is clear from achieved values that in NPK 20-8-8 fertilizer samples there are 92.25 % of particles with dimension from 3.15 to 5 mm and 7.0 % with dimension from 2 to 3.15 mm. In fertilizer Dolophos there are 50.87 % of particles with dimension from 3.15 to 5 mm and 47.54% with dimension from 2 to 3.15 mm.
COMPARISON OF CONCRETE COMPRESSIVE STRENGTH VALUES OBTAINED USING REBOUND HAMMER AND DRILLED CORE SPECIMENS
Authors: SADZEVICIUS Raimondas , SANKAUSKIENE Tatjana , MILIUS Petras
Published: February 2016

Durability of reinforced concrete structures depends on the maintenance conditions, surveillance, and well-timed repair of structures or reconstructions. Usually, the main attention falls on the durability determination based on the evaluation of change of main physical –mechanical properties, especially, on the compression strength of concrete. In this study, tests with the rebound hammer and concrete cores extracted from the existing reinforced concrete elements in hydraulic structures are presented. The comparison of strength values obtained with the rebound hammer and the concrete core specimens of reinforced concrete in hydraulic structures is carried out. The research was performed during the scientific expedition in the period of 2010–2014. The investigated objects are allocated in hydroschemes of Druskininkai, Marijampolė, Klaipėda districts. It was established that the results obtained using the non-destructive method were by 17 % higher than the ones obtained by performing the destructive test. However, it can be said that despite this fact, the non-destructive method offers simplicity and rapidity in use: test results are readily available on site and there is a possibility to test concrete strength of those structures where cores cannot be drilled due to thin-walled or densely reinforced structures.

Published: February 2016

The aim of this paper is a comparison of the operating parameters of combine harvesters in a selected farm. The working parameters were measured and evaluated on combine harvesters of the New Holland brand by different concepts of threshing. Field evaluation trials of combine harvester were carried out on private farm field in Central Bohemia region during the season of 2013 and 2014. Working parameters in this case mean the performance and economic indicators of the operation. Performance of the machines was measured per hectare, number of harvested hectares per day, respectively per hour or season. Fuel consumption was measured in litres and converted per hectare. Costs are calculated as fixed and variable and then summarized as total cost for a given machine. Experiments show differences in performance parameters of various threshing system of combine harvester. Tangential concept of NH CS660 had on average hourly performance of 3.1 ha h-1 the axial concept of NH CR960 had an average hourly performance of 4.6 ha h-1. Specific fuel consumption by the same throughput rate (6.5 kg s-1) is higher by using axial system (1.9 l t-1) than by tangential system (1.2 l t-1).
Predicting American Movie Genre Categories from Linguistic Characteristics
Authors: Berber Sardinha Tony , Veirano Pinto Marcia
Published: February 2016

The goal of the current study is to explore the possibility of correctly classifying movie transcripts into movie genres by means of a Discriminant Function Analysis (DFA) based on a previous comprehensive multidimensional (MD) analysis of American cinema. MD analysis is a framework for describing the salient characteristics of text varieties by means of multivariate statistical techniques, notably factor analysis. Traditionally, MD analysis has been restricted to the study of register variation, being largely ignored in text classification research. In the MD analysis reported, a large genre-diversified movie corpus was tagged for lexico-grammatical features with the Biber tagger and the resulting factor scores were used as input for the DFA. The results showed that particular movie genres could be successfully predicted from the MD analysis, thereby lending credence to movie genre distinctions, while at the same time stressing the robustness of MD factor scores as reliable predictors of genre distinctions.

Published: February 2016

ABSTRACT The objective of this study was to analyze the phenotypic correlation and path analysis of traits related to plant architecture, earliness and grain yield in F2, BC1 and BC2 generations, from crosses between cowpea cultivars BRS Carijó and BR14 Mulato. Most phenotypic correlations of the examined traits were concordant in statistical significance, with approximate values among the examined generations. For the trait seed weight, significant and positive phenotypic correlations were observed in the three generations only for the trait number of secondary branches. The values of the direct effects were in agreement with the values of the phenotypic correlations, which indicate true association by the phenotypic correlation among the traits of grain yield examined. Path analysis indicated that the selection of productive plants will result in early plants and an increased number of secondary branches. In F2, plants with shorter length of the main branch and shorter length of secondary branches can be obtained. The causal model explained 15 to 30% of the total variation in grain weight in relation to the traits examined. The analyses indicated the possibility of selecting plants with a higher and early grain yield, shorter length of primary branches and lower number of nodes, which are important variables for mechanical or semi-mechanical harvesting.

Published: February 2016

RESUMO O potássio (K) influencia diretamente a produtividade do coqueiro anão por ser ativador de enzimas envolvidas na respiração e fotossíntese, entre outras funções. No entanto em muitos casos sua aplicação no solo não tem proporcionado teores foliares adequados. Avaliou-se a influência de níveis de adubação potássica, com KCl, no solo e na axila foliar, nos teores de nutrientes em coqueiro anão verde (Cocos nucifera L.). O experimento foi conduzido, de 31/05/2007 a 31/05/2008, em pomar comercial, em Campos dos Goytacazes, em Neossolo Quartzarênico Órtico típico, no delineamento experimental em blocos casualizados, com cinco tratamentos e 16 repetições. Os tratamentos consistiram em duas formas de aplicação (no solo e na axila da folha 9) e dois níveis de KCl (1666 e 3333 g de KCl por planta, por ano), níveis 1 e 2 no solo e (833 e 1666 g planta-1 ano-1), níveis 1 e 2 na axila, parceladas em quatro aplicações sendo uma a cada três meses, além de uma testemunha sem KCl. Coletaram-se amostras foliares antes da primeira adubação e três meses após cada adubação. A aplicação de KCl proporcionou aumento dos teores foliares de K e de Cl e diminuiu o de Mg. Os teores foliares de N; P; Ca; S; B; Cu; Fe; Mn e Zn não foram influenciados pelos tratamentos. A aplicação de potássio na axila foliar permite maior absorção desse nutriente pelas plantas. A aplicação foliar minimiza as perdas e possibilita reduzir as quantidades de fertilizante potássico aplicadas.

Mudança organizacional e satisfação no trabalho: um estudo com servidores públicos do estado de Minas Gerais
Authors: Marques Antônio Luiz , Borges Renata , Reis Isabella do Couto
Published: February 2016

Resumo Um dos fatores importantes para compreender as causas da satisfação ou da insatisfação do trabalhador logo após um processo de mudança organizacional é identificar as reações do indivíduo a essa mudança na perspectiva de um contínuo, que varia entre resistência ativa em uma extremidade até cooperação total em outro extremo. Portanto, o objetivo deste estudo é compreender as implicações da mudança organizacional nos níveis de satisfação no trabalho, a partir das reações individuais à mudança. Com isso, foi realizado um survey no governo de Minas Gerais com 679 servidores para avaliar os impactos da avaliação de desempenho individual (ADI). Os dados obtidos por meio de questionários indicam que existe uma relação direta entre mudança e satisfação no setor público. Os resultados sugerem que os servidores que avaliam as mudanças de forma positiva e não resistem a elas estão mais satisfeitos com o trabalho.

Crescimento clássico e crescimento retardatário: um novo enfoque para políticas de desenvolvimento
Authors: MAGALHÃES JOÃO PAULO DE ALMEIDA
Published: February 2016

RESUMO O artigo defende a tese de que, diferentemente do que acontece nos países desenvolvidos, em que o crescimento depende dos níveis de poupanças e de inovações tecnológicas, nos países subdesenvolvidos o crescimento está condicionado à disponibilidade de mercado. Em termos de política econômica, isso significa que nos desenvolvidos o esforço deve ser no sentido da criação de poupanças e inovações tecnológicas de nível adequado, enquanto nos subdesenvolvidos o importante é garantir mercado do dinamismo e dimensões necessários à eliminação de seu atraso econômico. O não reconhecimento dessa diferença, resultante de a Economia do Desenvolvimento não ter proposto modelo específico para o crescimento retardatário, tem levado a sérios erros nas políticas de desenvolvimento.
From gold money to fictitious money
Authors: PRADO ELEUTÉRIO F. S.
Published: February 2016

ABSTRACT In the nineteenth century, money appear primarily as gold. In the twenty-first century, it appears as strictly fiduciary money. It is known that Marx said very clearly that the golden money was the effective basis of the monetary and credit system. Had the historical development finally shown that his theory of value and money would be false? Marxists have struggled continually with this problem. This paper tries to show that exist a simple and good answer to this crucial question. It comes just developing a little the dialectics of commodities and money found on Marx's Capital.
The concept of emerging power in international politics and economy
Authors: FONSECA PEDRO CEZAR DUTRA , PAES LUCAS DE OLIVEIRA , CUNHA ANDRÉ MOREIRA
Published: February 2016

ABSTRACT This paper aims to analyze the concept of emerging power established to the understanding of international affairs. The work observes that the use of the lexicon emerging - regarding to markets, countries or powers - as qualifier for a range of international relations phenomena became a constituent part of the matter. In spite of that, the empirical denotation of the predicate is ahead of the amount of efforts on its theoretical contextualization. Our methodological hypothesis is that the rational denial of the concepts prevailing connotative spectrum by acknowledging the embedded wisdom about cognate phenomena synthesizes a theoretical framework on its accurate use.

Published: February 2016

RESUMO Provavelmente, a questão do método seja uma das mais controvertidas discussões relacionadas à obra de Keynes. As controvérsias podem ser resumidas em três principais linhas: (i) o atomismo ou o organicismo como unidade de análise econômica de Keynes; (ii) a continuidade ou a descontinuidade das bases filosóficas, em termos epistemológicos e metodológicos, do pensamento de Keynes; e (iii) a especulação acerca do método científico utilizado por Keynes. O objetivo do artigo centra-se na última das linhas da controvérsia, qual seja, discutir o método científico na obra de Keynes. Subjacente a tal objetivo, apesar dos indícios de que o método do autor está relacionado tanto ao indutivo quanto ao histórico-indutivo, explorar-se-á o primeiro método, uma vez que, por um lado, ele diz respeito à teoria do conhecimento (epistemologia) desenvolvida por Keynes em seu Treatise on Probability e, por outro lado, ele está presente em algumas de suas importantes obras econômicas.

ABSTRACT The present study aims to evaluate crop, pasture and forest land prices in Brazil, between 1994 and 2010, in the light of Post-Keynesian theory. The results provide evidence that land, more than just a simple factor of production, must be conceived of as an economic asset. In fact, the price of rural land is determined not only by the expected profitability deriving from agricultural activities but also by the agents' expectations about its future appreciation and liquidity in an economic environment permeated with uncertainty. In this context, as an object of speculation, land has been particularly important as a store of value.

RESUMO Este texto discute os dados e os principais fatos estilizados da dinâmica da formação bruta de capital fixo (FBCF) no brasil após 1995. apresenta, ademais, especificações econométricas para a dinâmica trimestral da FBCF no período 1996-2012 que levantam hipóteses causais ainda relativamente inexploradas na literatura. os dados apresentados evidenciam as dinâmicas distintas da FBCF em máquinas e equipamentos e construções - e, consequentemente, o papel fundamental da primeira variável na dinâmica da FBCF total da economia. as estimativas apresentadas sugerem choques cambiais, nos preços internacionais de commodities e na FBCF pública como mecanismos causais da dinâmica trimestral da FBCF brasileira.
Goldmann e o estruturalismo genético
Authors: Löwy Michael
Published: February 2016

Resumo: O presente artigo é resultante de palestra proferida pelo Professor Michael Löwy na PUC-SP em 1985 sobre a obra de Goldmann, em particular do conceito de estruturalismo genético, inspirado na obra de Marx, para designar o método dialético. O estruturalismo genético é um conceito amplo, compreendido enquanto método que busca analisar totalidades estruturadas, e observar qual é a dialética entre o todo e as partes. Goldmann foi influenciado pela obra de Lukács, pela epistemologia genética de Piaget, enfatizando o processo histórico de constituição do objeto na sua totalidade e de constituição de sujeitos coletivos, na qual as classes sociais apresentam centralidade. O conceito tem aplicação no terreno particular da cultura, mas também como definição de método das ciências sociais e de aplicação em todos os terrenos do conhecimento social.

Resumo: Este artigo consolida resultados de uma pesquisa realizada em dez municípios brasileiros, que buscou analisar a dinâmica de acompanhamento das condicionalidades de saúde do Programa Bolsa Família. A ideia central consistiu em abordar variáveis que poderiam afetar o desempenho municipal na gestão do programa, tais como: porte populacional e magnitude da população a ser coberta; estrutura e capacidade técnico-gerencial dos municípios; oferta e organização da Atenção Básica em Saúde e arranjos intersetoriais.
EVIDÊNCIAS ARQUEOLÓGICAS PARA A ORIGEM DOS TUPI-GUARANI NO LESTE DA AMAZÔNIA
Authors: Almeida Fernando Ozorio de , Neves Eduardo Góes
Published: February 2016

Resumo Grupos falantes de línguas da família Tupi-Guarani estavam espalhados por vastas regiões da América do Sul na época da chegada dos europeus. Durante décadas, especulou-se sobre o processo de dispersão desses grupos por um território tão grande. Neste artigo indica-se que o estudo da história dos grupos falantes de línguas tupi-guarani da Amazônia Oriental, produtores de cerâmica da Subtradição Tupinambá da Amazônia, é uma peça fundamental para a compreensão de fenômenos de mobilidade e da complexidade interna dos Tupi-Guarani.
O Comportamento do Preço da Terra Agrícola: um modelo de painel de dados espaciais

Published: February 2016

Resumo: O presente artigo analisou o comportamento do preço da terra agrícola nos municípios do Paraná no período de 1999-2011. Partindo da revisão bibliográfica dos principais estudos nacionais sobre o tema, foi possível identificar os determinantes do preço da terra e os métodos utilizados. Neste sentido, optou-se por estimar um modelo para o preço da terra via painel de dados espaciais. As estimativas indicaram que o valor bruto da produção agropecuária, a valorização patrimonial, o financiamento total à agropecuária, a relação investimento-receita municipal, o percentual da área plantada do município com soja e a incorporação da dependência espacial do preço da terra são variáveis que explicam o preço da terra no estado do Paraná. Estas explicariam 84% dos preços e indicaram que há maior ajuste intrapainel, sendo os efeitos espaciais mais intensos no próprio município e em relação ao todo. Em especial, o modelo proposto avançou em termos estruturais, com a incorporação de variáveis coletadas para todos os 399 municípios do Paraná, e em termos metodológicos, ao estimar via painéis de dados a influência dos efeitos de espacialidade sobre o preço da terra agrícola, destacando a importância da localização e da vizinhança na determinação de tal preço.

Resumo: O estudo teve por objectivo fazer a caracterização dos atributos de qualidade de duas variedades (Solo e Local) de papaia produzida em Santiago, Cabo Verde, e definir os atributos que os distribuidores procuram. Foram realizadas avaliações físico-químicas, sensorial e um estudo de mercado. Os parâmetros avaliados foram o peso, cor interior e exterior, textura, espessura da polpa, pH, acidez titulável, SST, fez-se avaliação sensorial a aplicação de um questionário aos importadores de papaia. Os parâmetros SST, Acidez, pH e peso variam significativamente com as variedades, sendo as papaias da variedade Local mais pesadas. A textura varia em função dos graus de maturação, a firmeza apresenta uma diminuição ao longo do amadurecimento, na deformação percebe-se um decréscimo com o avançar da maturação, nos parâmetros de cor interna e externa as diferenças encontram-se na interação entre Variedade e Estado de maturação. A variedade Solo foi mais valorizada na avaliação sensorial assim como no preço, certificação/selo qualidade e doçura pelos distribuidores.

Resumo: O aumento da pressão sobre os recursos hídricos tem levado muitos países a reconsiderarem os mecanismos utilizados na indução do uso eficiente da água, especialmente na agricultura irrigada. Estabelecer o preço correto da água é um dos mecanismos de tornar mais eficiente a alocação da água. O presente trabalho tem como objetivo a análise dos impactes económicos, sociais e ambientais de políticas de preço da água. A metodologia utilizada foi a Programação Linear, aplicada ao Perímetro Irrigado do Vale de Caxito, Província do Bengo, a 45 km de Luanda, que tem como fonte o rio Dande. Foram testados três cenários relativos a políticas de tarifação de água: tarifa volumétrica simples, tarifa volumétrica variável, e tarifa fixa por superfície. As principais conclusões mostram que, do ponto de vista do uso eficiente da água na agricultura, os melhores resultados obtêm-se com a tarifa volumétrica variável; do ponto de vista social, a tarifação volumétrica simples apresenta os melhores resultados; o método de tarifa volumétrica variável foi o mais penalizador, reduzindo rapidamente a área das culturas mais consumidoras de água, sendo o melhor do ponto de vista ambiental. Qualquer um dos métodos traz aspetos negativos relativamente à redução da margem bruta total.
