Cinema attendance during crises is there a relationship between cinema attendance and the state of the economy in France in the period 1992-2012?

O presente estudo teve como objetivo testar se a situação econômica teve um impacto sobre os hábitos de consumo de cinema na França, no período contemporâneo (1992-2012). O estudo aborda a relação entre indicadores econômicos e consumo de cinema em um nível agregado e, em seguida, analisa se os vários tipos de filmes, tipos de cinemas e categorias de cinéfilos foram mais ou menos foram afetados pelo estado da economia. No nível agregado, estudos semelhantes já foram realizados em outros países. Este estudo confirma os resultados para a França: como em outros países desenvolvidos, a situação da economia tem pouca influência no consumo de cinema e o setor é resiliente. Este trabalho também traz novas análises detalhadas sobre o comportamento de vários sub-tipos de filmes, segmentos de locais e categorias de consumidores. Ele demonstra que para a maior parte dessas sub-categorias, drivers do mercado são oferta e preço, e que a situação da economia tem pouca influência. Quanto ao tipo de cinema, o estudo argumenta que, comparativamente, cinemas grandes conseguem crescer durante o período de crise.

Estrutura e dinâmica da interação de éteres de celulose com surfactantes

As técnicas de fluorimetria, condutometria, viscosimetria, turbidimetria, espalhamento de luz e espalhamento de raios-X a baixo ângulo (SAXS) foram empregadas no estudo da agregação de diferentes surfactantes aniônicos em presença de soluções aquosas diluídas de (hidroxipropil)celulose (HPC) 0,25% m/m, (hidroxipropilmetil)celulose (HPMC) 0,20% m/m e HPMC 0,10% m/m / NaCl 0,10 mol L-1. Também foram investigadas através de SAXS soluções concentradas de HPC (30, 40 e 50% m/m). Admitindo-se uma faixa geral de concentração, entre 10-4 e 10-1 mol L-1, foram utilizados neste estudo os surfactantes colato de sódio (CS), deoxicolato de sódio (DC), derivados dos sais biliares, e o alquilsintético dodecilsulafato de sódio (SDS). Observou-se que os polímeros contribuem diferentemente no processo de agregação de cada surfactante, evidenciado pela mudança dos valores da concentração de agregação crítica (CAC) em relação à concentração micelar crítica (CMC). Os resultados condutométricos confirmaram a interação éteres de celulose/sais biliares, embora a mesma tenha se mostrado mais fraca em relação a éteres de celulose/SDS. Os dados termodinâmicos demonstraram que a formação de agregados polímero/surfactante apresenta maior estabilidade do que as próprias micelas livres. Os resultados de viscosimetria e turbidimetria evidenciaram as diferenças estruturais entre HPC e HPMC, assim como entre os surfactantes. Através do espalhamento de luz dinâmico, verificou-se a existência de dois modos de correlação, rápido e lento. O primeiro é atribuído à cadeia polimérica isolada, agregados polímero/surfactante intramoleculares ou mesmo a micelas livres. Por sua vez, o modo lento relaciona-se a clusters poliméricos ou agregados polímero/surfactante intermoleculares. Adicionalmente, as curvas de distribuição dos tempos de relaxação demonstraram a influência de cada surfactante sobre a dinâmica dos polímeros. Tal influência é percebida antes mesmo da CAC, contrariando o modelo da interação polímero/surfactante proposto por Cabane. Os resultados de SAXS acusaram a formação de domínios líquido-cristalinos em xx soluções concentradas de HPC, assim como confirmaram a presença de micelas livres a altas concentrações de surfactantes nos sistemas diluídos. Em linhas gerais, os resultados indicaram a interação dos polímeros com SDS mais efetiva do que os mesmos polímeros e os sais biliares. No que tange à natureza do polímero, a HPC mostrou uma maior estabilidade na sua interação com os surfactantes do que a HPMC.

Trabalho escravo contemporâneo e Estado capaz no Brasil

This thesis demonstrates the exercise of slave labor in the context of free or decent work, in contemporary times, supported by the federal constitution 1988 Brazil than places like fundamentals "the dignity of the human person" and "the social values of work and free enterprise" , and is as fundamental objectives of the Federative Republic of Brazil "build a free, just and united society," "guarantee national development", "eradicate poverty and marginalization and reduce social and regional inequalities", "promote the well all without prejudice of origin, race, sex, color, age and any other forms of discrimination. " It is considered that the analytical work category interacts both conceptually as an integral part of the capitalist development model as a driving force to the definition of State Capable. The panorama of acquired rights and rights infringed upon evidences the presence, or not, of the Brazilian state. Highlights, however, as state functions are being performed under the auspices of the Democratic State of Rights. So the original question that motivated this work is: To what extent the Brazilian government is structured to implement measures that can eradicate modern-day slavery? This question led to questions as: The Brazilian state has never failed in implementing the policy of "eradication to work analogous to slavery"? The answer the research questions were outlined using the dialectical materialist historical method under a sociological perspective in order to draw relationships and interrelationships between the current situation of the concept contemporary slavery and its historical roots. In the theoretical framework considers the conceptual approach regarding the capable state in order to answer the question regarding the eradication policy to contemporary forced labor and the Brazilian nation-state's ability to put it into action. In this sense, it employed concepts such as state, nation-state and capable state, from the interpretations of Bresser-Pereira, including the discussion regarding the formation of the arrangements and conservative and progressive political alliances. The research subject was analyzed from the reports published in 2013 by the Ministry of Labour after the Special Group of the inspection actions for Mobile Inspection (GEFM) to Combat Labour Analogous to Slave. The study of public policies related to the eradication program to work analogous to slavery takes up the discussion regarding the conditionality of free labor, or decent, in contemporary Brazil, and reveals that in Brazil the effectiveness or efficacy of government actions comply with governing the Federal Constitution-88, namely, to preserve "the dignity of the human person" and "the social values of work and free enterprise" is an ongoing process. There are advances, but these are conditioned to Brazil stage in the formation of the nation state and the national society.

Homogeneous middles vs. heterogeneous tails, and the end of the ‘Inverted-U’: the share of the rich is what it’s all about

This paper examines the current global scene of distributional disparities within-nations. There are six main conclusions. First, about 80 per cent of the world’s population now live in regions whose median country has a Gini not far from 40. Second, as outliers are now only located among middle-income and rich countries, the ‘upwards’ side of the ‘Inverted-U’ between inequality and income per capita has evaporated (and with it the statistical support there was for the hypothesis that posits that, for whatever reason, ‘things have to get worse before they can get better’). Third, among middle-income countries Latin America and mineral-rich Southern Africa are uniquely unequal, while Eastern Europe follows a distributional path similar to the Nordic countries. Fourth, among rich countries there is a large (and growing) distributional diversity. Fifth, within a global trend of rising inequality, there are two opposite forces at work. One is ‘centrifugal’, and leads to an increased diversity in the shares appropriated by the top 10 and bottom 40 per cent. The other is ‘centripetal’, and leads to a growing uniformity in the income-share appropriated by deciles 5 to 9. Therefore, half of the world’s population (the middle and upper-middle classes) have acquired strong ‘property rights’ over half of their respective national incomes; the other half, however, is increasingly up for grabs between the very rich and the poor. And sixth, Globalisation is thus creating a distributional scenario in which what really matters is the income-share of the rich — because the rest ‘follows’ (middle classes able to defend their shares, and workers with ever more precarious jobs in ever more ‘flexible’ labour markets). Therefore, anybody attempting to understand the within-nations disparity of inequality should always be reminded of this basic distributional fact following the example of Clinton’s campaign strategist: by sticking a note on their notice-boards saying “It’s the share of the rich, stupid”.

Turnout and quorum in referenda

We analyse the effect of turnout requirement in referenda in the context of a group turnout model. We show that a participation quorum requirement may reduce the turnout so severely that it generates a "quorum paradox": in equilibrium, the expected turnout exceds the participation quorum only if this requirement is not imposed. Moreover, a participation quorum does not necessarily imply a bias for the status quo. We also show that in order to induce a given expected turnout, the quorum should be set at a level that is lower than half tha target, and the effect of a participation quorum on welfare is ambiguous. On the one hand, the quorum decreases voters' welfare by misrepresenting the will of the majority. On the other hand, it might also reduce the total cost of voting. Finally, we show that an approval quorum is essentially equivalent to a participation quorum.

Compósitos Portland-biopolímeros para cimentação de poços de petróleo

The oil production in mature areas can be improved by advanced recovery techniques. In special, steam injection reduces the viscosity of heavy oils, thus improving its flow to surrounding wells. On the other hand, the usually high temperatures and pressures involved in the process may lead to cement cracking, negatively affecting both the mechanical stability and zonal isolation provided by the cement sheath of the well. The addition of plastic materials to the cement is an alternative to prevent this scenario. Composite slurries consisting of Portland cement and a natural biopolymer were studied. Samples containing different contents of biopolymer dispersed in a Portland cement matrix were prepared and evaluated by mechanical and rheological tests in order to assess their behavior according to API (American Petroleum Institute) guidelines. FEM was also applied to map the stress distribution encountered by the cement at bottom bole. The slurries were prepared according to a factorial experiment plan by varying three parameters, i.e., cement age, contents of biopolymer and water-to-cement ratio. The results revealed that the addition of the biopolymer reduced the volume of free water and the setting time of the slurry. In addition, tensile strength, compressive strength and toughness improved by 30% comparing hardened composites to plain Portland slurries. FEM results suggested that the stresses developed at bottomhole may be 10 to 100 times higher than the strength of the cement as evaluated in the lab by unconfined mechanical testing. An alternative approach is proposed to adapt the testing methodology used to evaluate the mechanical behavior of oilwell cement slurries by simulating the confined conditions encountered at bottornhole

Contribuição ao estudo da isonomia na tributação sob a perspectiva da ordem econômica

The study aims to investigate the limits of state intervention via induction on Economic Order, especially in cases regarding tax equality, through the analysis of their effects on economic development and on free competition from the perspective of economic efficiency and the Constitution. Thus, the work seeks to demonstrate that the achievement of equality in taxation is important in that it strengthens the economic relations in terms of efficiency, protects competition and fosters economic development to reduce regional and social inequalities and other constitutional desiderata. A dissertation is characterized by interdisciplinarity and was divided into two parts. The first is to discuss the legal meaning of equality from the doctrinal analysis of the principle and the relationship between equality and justice in the economic sense without rejecting its philosophical content. It is noteworthy that hermeneutics and the philosophy of language are useful tools for achieving equality in presenting the pragmatic methodologies applicable to the subject in terms of corrective justice. Based on these general assumptions, is going to study the tax equality and their characteristics, the corollary of the ability to pay and its relation to the economic capacity and the issue of progressivity in taxation as an ideal of distributive justice. The second part concerns the legal foundations of Economic Order and its relation to extrafiscality as a means of economic regulation in order to investigate the efficiency of this induction in order to promote economic development, free competition and tax equality itself to reduce inequalities and distributing wealth. Within this context, we investigated the scope of the constitutional principles of economic order, free enterprise and free competition, and favored differential treatment for small and medium enterprises, the issue of regional development for the reduction of regional and social inequalities, the problem the "fiscal war" and finally the efficiency from the perspective of Economic Analysis of Law

Livre expressão :para que te quero? o interesse público no ensino do Jornalismo

The main objective of this research was studying the meanings of the freedom of expression and what professors of Journalism think about the way those meanings are used in pedagogical practices. The term freedom of expression is commonly used in journalism even though it is not so studied, consequently we don t have a word to define it. Therefore, we related the term freedom of expression in Journalism teaching to the condition as the object of this study, aiming to establish a connection among the term, the right, free expression and the endurance of the right. The theorical support to understand the dynamic of the meanings of the freedom of expression in the social practice of Journalism teaching was based in the Hegeliana dialetic theorical principles and in the language philosophy more specifically in Bakhtin s perspective from which we can mention the social auditorium, immediate conditions of production and a wider social horizon as the main categories of analysis. This study is a qualitative research with an interacionist perspective anchored in a semi-structured interview as a privileged method of data collecting made with ten professors from Journalism graduation. The analysis reveals that, in the interviewers perspective, there would be a deceiving practice from freedom of expression in the journalism teaching in which emerges either in speeches with handbills spreading the fear and/or under a stimulus form to concealment

ACUTE TOXICITY and ENVIRONMENTAL RISK of OXYTETRACYLINE and FLORFENICOL ANTIBIOTICS TO PACU (Piaractus mesopotamicus)

The oxytetracyline (OTC) and florfenicol (FLO) are the most used antibiotics for bacterial disease control in fish. The aims are: estimating the lethal concentration 50% initial (LC(I) 50;48h) of OTC (Terramicina (R)) and FLO (Aquaflor (R)) for pacu (Piaractus mesopotamicus); classifying OTC and FLO according to the acute toxicity and the risk of environmental intoxication; and assessing OTC and FLO dilution effect in water quality variables. Fish were acclimatized for 10 days in a bioassay room at 27 +/- 2 degrees C. Then nine animals (three each concentration) were exposed to 7.0; 7.5; 8.0 or 8.5 mg L(-1) of OTC or to 600.0; 700.0; 800.0; 900.0 and 1000.0 mg L(-1) of FLO and a control treatment. The water quality variables recorded daily were: pH, temperature, electric conductivity, and dissolved oxygen. OTC and FLO were classified according to acute toxicity and environmental risk. The estimated OTC LC(I) 50;48h for pacu is 7.6 mg L(-1) and the estimated FLO is > 1000 mg L(-1). OTC reduced the dissolved oxygen concentration, and it was considered moderately toxic, causing risk of environmental intoxication to pacu. FLO is not toxic; it does not cause risk of environmental intoxication to pacu and does not change water quality variables.

Observations on helminth infections of free-living and captive rheas (Rhea americana) in Brazil

The present work describes helminth infection of eight free-living and 12 captive rheas (Rhea americana) from, respectively, Pantanal of Mato Grosso do Sul State, and Jaboticabal, São Paulo State, Brazil. Captive birds were young and had a high mortality rate, while free-living birds were adult and apparently healthy. Infections were evaluated by post-mortem examination of internal organs and recovery of helminths using standard parasitological procedures. Seven species of nematodes (Sicarius uncinipenis, Torquatoides crotophaga, Deletrocephalus dimidiatus, D. cesarpintoi, Paradeletrocephalus minor, Capillaria venteli and Dicheilonema rheae) and two species of cestodes (Houttuynia struthionis and Chapmania tauricolis) were identified. P. minor, which inhabits the large intestine, was the most common helminth in free-living birds (63.9%). In captive rheas, a mean parasitic load of 173 helminths per host was found. The gizzard of these birds was the most parasitized organ and S. uncinipenis was most common (92.5%). Parasitism of free-living and captive birds and associated pathology are discussed.

A escrita e a criança com síndrome de Down: uma relação possível na escola regular

The school inclusion is based on respect for diversity and the belief that everyone has the capacity to learn and develop, for this the school needs to prepare itself to meet the differences and provide a meaningful learning for everyone, including those with Down syndrome. It is in the interaction with others that children develop their skills and exchange substantial experiences to learn the school and non school knowledge. Among the knowledge the school must offer students, there is one that is indispensable to the present society; the writing, because writing is a way to Interact, to communicate and to build autonomy to relate in society. Before exposed, the research that started this study aimed to investigate the level of the writing conceptualization of children with Down syndrome during the literacy process in a regular school of the private school network in the city of Natal/RN. For carrying out this study, initially we conducted a qualitative research, using the bibliographical as a methodological recourse, seeking to the deepening of information, based on the literature about the subject, which allowed us to collect data about people with Down syndrome, their education and the process of the writing acquisition. Later, a case study was performed, involving free observation in the room and interviews with teachers and children, trying to verify how this writing acquisition process occurs by children with Down syndrome. The data analyzed and information recorded demonstrated that the school inclusion, when taken seriously, benefits the learning of writing for children who have intellectual deficit, and, mainly, they develop in this environment and are able to learn to write, as long as their own pace are respected

A precarização do trabalho do enfermeiro na estratégia saúde da família: contribuição ao debate

This study makes an analysis of the work of nurse of the, uncovering the meaning of work and of precarious work for the nurse. aims to analyze the forms of precariousness of work of the nurse of Family Health Strategy the municipality of Pau dos Ferros-RN, Brazil. This is a qualitative study with analysis of the categories that emerged from search through dialog with the authors studied in theoretical framework of the sense of human work, the world of work actual and the precariousness of work in health. Used if the methodology of thematic oral history and semi-structured interview as an instrument for data collection and information. Participated 07 nurses of. There was predominance of females, with civil state married, with age between 29 and 47 years, inserted as nurses in Family Health Strategy 1 to 9 years. All referred satisfaction with work. Emerged 02 main meanings of work, whichever the design of work as a source of human and practical transforming of reality, with the sense of perform an action by the individual facilitator and suffers change. Include the precarious work not only as the absence of links labor and social protection, unlike the thought of the Ministry of Health, similar to the design of the study, the precariousness understood yet as the absence of participation of workers in the spaces work management and running of the work and the absence of structural conditions and infra-structural where the work process takes place. evidenced the totality of nurses inserted in Family Health Strategy by public tender. Refer have labor rights guaranteed. Don´t include under which legal arrangements are governed. The researched reality does not have a policy desprecarização nursing work of Family Health Strategy. Concluded the municipality presents progress and setbacks for the precariousness of work of the nurse of Family Health Strategy. The collective work in health is a challenge in researched reality and the policy of desprecarização of the work of the management of education and work was not evidenced. Despite the implementation of the public tender these professionals have a degree of precariousness of work, with the accumulation gradient of responsibilities, some lack of working conditions in structural aspects, infra-structural and means and instruments

Síntese e caracterização de aluminofosfato impregnado com molibdênio/zinco visando a dessulfurização por adsorção

Discussions about pollution caused by vehicles emission are old and have been developed along the years. The search for cleaner technologies and frequent weather alterations have been inducing industries and government organizations to impose limits much more rigorous to the contaminant content in fuels, which have an direct impact in atmospheric emissions. Nowadays, the quality of fuels, in relation to the sulfur content, is carried out through the process of hydrodesulfurization. Adsorption processes also represent an interesting alternative route to the removal of sulfur content. Both processes are simpler and operate to atmospheric temperatures and pressures. This work studies the synthesis and characterization of aluminophosphate impregnate with zinc, molybdenum or both, and its application in the sulfur removal from the gasoline through the adsorption process, using a pattern gasoline containing isooctane and thiophene. The adsorbents were characterized by x-ray diffraction, differential thermal analysis (DTG), x-ray fluorescence and scanning electron microscopy (SEM). The specific area, volume and pore diameter were determined by BET (Brunauer- Emmet-Teller) and the t-plot method. The sulfur was quantified by elementary analysis using ANTEK 9000 NS. The adsorption process was evaluated as function of the temperature variation and initial sulfur content through the adsorption isotherm and its thermodynamic parameters. The parameters of entropy (ΔS), enthalpy variation (ΔH) and free Gibbs energy (ΔG) were calculated through the graph ln(Kd) versus 1/T. Langmuir, Freundlich and Langmuir-Freundlich models were adjusted to the experimental data, and the last one had presented better results. The thermodynamic tests were accomplished in different temperatures, such as 30, 40 and 50ºC, where it was concluded the adsorption process is spontaneous and exothermic. The kinetic of adsorption was studied by 24 h and it showed that the capability adsorption to the adsorbents studied respect the following order: MoZnPO > MoPO > ZnPO > AlPO. The maximum adsorption capacity was 4.91 mg/g for MoZnPO with an adsorption efficiency of 49%.
