Os cadernos de física: algumas inquietações sobre o currículo oficial do Estado de São Paulo

The assumptions of Marxist philosophy helps us understand the inherent contradictions of the historical process. The category mode of production is understood as the means and the ends for which mankind produces and reproduces reality objectively and subjectively. The temporal evolution of the mode of production has spurred antagonistic social classes, which are the world capitalist bourgeoisie and proletariat. At the rise of the current mode of production each class produced a pedagogy according to your interests. The proposal of the workers is centered on unity between teaching and non-alienated labor, enabling the development of human potential and building a new social order. The last historical period was marked by the implementation of the neoliberal agenda to reduce social spending and market liberalization. The educational reforms of the state of São Paulo followed the same goals. From the program São Paulo Faz Escola, São Paulo School Curriculum was introduced in the State of São Paulo, which integrates several documents. The Student Notebook, separated by discipline and delivered bimonthly to students of public schools, is one of those publications. Specifically, the physics notebook brings a content with no depth, where theories are presented by minimizing the mathematical formalism for a broad education that meets the needs for dynamize the economy

A indústria farmacêutica no Brasil: um estudo do impacto socioeconômico dos medicamentos genéricos

Recently, some countries outside the Triad (Japan, Europe and the United States) have assumed an important role in the pharmaceutical scenario, as large producers, among them stand out Brazil. In the 90s, there were major institutional transformations and the pharmaceutical industry has undergone a reverse specialization process, because liberalization has discouraged production of pharmaceutical chemicals and dependence of imports increased. The law of generics medicines in 1999 emerged as an attempt to increase the population's access to medicines equivalent to ones with brand, with more affordable prices. As a result of this law there was a strengthening of the national capital and a major attraction for foreign companies to brazilian market. This study aims to assess the development trajectory of the country, showing how path-dependence has culminated in greater empowerment of national pharmaceutical industries after the Generics Law in 1999

O comércio internacional de tecnologias ambientais: a inserção do Brasil e da China

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)

Estratégias de política de desenvolvimento industrial pós-abertura econômica

This work intends to analyze the industrial policy strategies adopted by Brazil after economic liberalization. Initially will be compared the different views around the problem: the liberal model, which advocates less state involvement and horizontal policies, and the model that advocates active industrial policies with participation of the state and that are based on the South Korean model. The South Korean experience will be analyzed, especially for evaluation of consistency between objectives and instruments. Will be analyzed also the liberal strategies implemented by Brazil during the 1990s, and finally, the policies adopted after 2003, highlighting objectives, instruments and results by 2014

Políticas e desenvolvimento do estado de Mato Grosso após abertura comercial: análise da visão de dois empresários atuantes no setor

After realizing two interviews, with distinct managers/businessmen working in the cotton industry, the objective is to put in evidence the political, economical and social factors that contributed to the formation and configuration of the Mato Grosso state, after the trade liberalization that occurred in the early 90's, it's effects and consequences in the eyes of the interviewed. The study of public policies is primordial to the discovery of the configuration of determined place, evaluating advances and possible errors in the social, economical and environmental areas. Through the analysis of the interviews it has been found that the urban centers have been developing with a direct link to the industrial activities related to agriculture and that the labor work force have also been attracted because of these changes, and as a consequence this labor force is now becoming more specialized to be able to accompany the jobs requirements in the industry. Analyzing the interviews, it is possible to highlight some information about the development of Mato Grosso, among those the following factors and public policies. The creation and expansion of the cities in the state are possible through public and private investment in infrastructure the socioeconomic development of the state is linked with the advances made in the private sector that grows because of advances made in crops technology in contrast to the occupation of the cerrado, in relation to the cotton crops. The problems that Mato Grosso is facing are mainly linked to the region infrastructure, that can count on investment plans to transportation and production flow that dates before the globalization era. The pattern that is seen today with top of the line agricultural production, big monoculture with high productivity and the arrival of multinational giants, was implanted because of two important events: the trade liberalization in the 1990's and the cambial depreciation in the 1999's...

Learning Democracy Together in School? : Student and Teacher Attitudes in Bosnia and Herzegovina

The principal aim of this study is to examine attitudes and values, through questionnaires, among students and teachers in the last grade of primary school (grade 8) regarding issues related to authoritarianism, democracy, human rights, children rights, conflict resolution and legislation in Bosnia and Herzegovina. A second aim is to explore and analyze the role of the international community in the democratization and education processes in the light of globalization in this country through secondary sources of data, site visits and observations. Analysis of the student sample reveals suspicion towards democracy, especially when democracy was associated with politics and politicians. When the issue of democracy was de-contextualized from Bosnia and Herzegovina realities in the questionnaire, students showed more positive attitudes towards it. Students generally agreed with very strong authoritarian statements. High achieving students were more democratic, more socially responsible, more tolerant regarding attitudes towards religion, race and disabilities, and less authoritarian compared to low achievers. High achievers felt that they had influence over daily events, and were positive towards social and civil engagement. High achievers viewed politics negatively, but had high scores on the democracy scale. High achievers also agreed to a larger extent that it is acceptable to break the law. The more authoritarian students were somewhat more prone to respond that it is not acceptable to break the law. The major findings from the teacher sample show that teachers who agreed with non-peaceful mediation, and had a non-forgiving and rigid approach to interpersonal conflicts, also agreed with strong authoritarian statements and were less democratic. In general, teachers valued students who behave respectfully, have a good upbringing and are obedient. They were very concerned about the general status of education in society, which they felt was becoming marginalized. Teachers were not happy with the overloaded curricula and they showed an interest in more knowledge and skills to help children with traumatic war experiences. When asked about positive reforms, teachers were highly critical of, and dissatisfied with, the educational situation. Bosnia and Herzegovina is undergoing a transition from a state-planned economy and one party system to a market economy and a multi party system. During this transition, the country has become more involved in the globalization process than ever. Today the country is a semi-protectorate where international authorities intervene when necessary. The International community is attempting to introduce western democracy and some of the many complexities in this process are discussed in this study. Globalization processes imply contradictory demands and pressures on the education system. On one hand, economic liberalization has affected education policies —a closer alignment between education and economic competitiveness. On the other hand, there is a political and ideological globalization process underlying the importance of human rights, and the inclusiveness of education for all children. Students and teachers are caught between two opposing ideals — competition and cooperation.

Development and characterization of a distributed measurement system for the evaluation of voltage quality in electric power networks

The research activity carried out during the PhD course in Electrical Engineering belongs to the branch of electric and electronic measurements. The main subject of the present thesis is a distributed measurement system to be installed in Medium Voltage power networks, as well as the method developed to analyze data acquired by the measurement system itself and to monitor power quality. In chapter 2 the increasing interest towards power quality in electrical systems is illustrated, by reporting the international research activity inherent to the problem and the relevant standards and guidelines emitted. The aspect of the quality of voltage provided by utilities and influenced by customers in the various points of a network came out only in recent years, in particular as a consequence of the energy market liberalization. Usually, the concept of quality of the delivered energy has been associated mostly to its continuity. Hence the reliability was the main characteristic to be ensured for power systems. Nowadays, the number and duration of interruptions are the “quality indicators” commonly perceived by most customers; for this reason, a short section is dedicated also to network reliability and its regulation. In this contest it should be noted that although the measurement system developed during the research activity belongs to the field of power quality evaluation systems, the information registered in real time by its remote stations can be used to improve the system reliability too. Given the vast scenario of power quality degrading phenomena that usually can occur in distribution networks, the study has been focused on electromagnetic transients affecting line voltages. The outcome of such a study has been the design and realization of a distributed measurement system which continuously monitor the phase signals in different points of a network, detect the occurrence of transients superposed to the fundamental steady state component and register the time of occurrence of such events. The data set is finally used to locate the source of the transient disturbance propagating along the network lines. Most of the oscillatory transients affecting line voltages are due to faults occurring in any point of the distribution system and have to be seen before protection equipment intervention. An important conclusion is that the method can improve the monitored network reliability, since the knowledge of the location of a fault allows the energy manager to reduce as much as possible both the area of the network to be disconnected for protection purposes and the time spent by technical staff to recover the abnormal condition and/or the damage. The part of the thesis presenting the results of such a study and activity is structured as follows: chapter 3 deals with the propagation of electromagnetic transients in power systems by defining characteristics and causes of the phenomena and briefly reporting the theory and approaches used to study transients propagation. Then the state of the art concerning methods to detect and locate faults in distribution networks is presented. Finally the attention is paid on the particular technique adopted for the same purpose during the thesis, and the methods developed on the basis of such approach. Chapter 4 reports the configuration of the distribution networks on which the fault location method has been applied by means of simulations as well as the results obtained case by case. In this way the performance featured by the location procedure firstly in ideal then in realistic operating conditions are tested. In chapter 5 the measurement system designed to implement the transients detection and fault location method is presented. The hardware belonging to the measurement chain of every acquisition channel in remote stations is described. Then, the global measurement system is characterized by considering the non ideal aspects of each device that can concur to the final combined uncertainty on the estimated position of the fault in the network under test. Finally, such parameter is computed according to the Guide to the Expression of Uncertainty in Measurements, by means of a numeric procedure. In the last chapter a device is described that has been designed and realized during the PhD activity aiming at substituting the commercial capacitive voltage divider belonging to the conditioning block of the measurement chain. Such a study has been carried out aiming at providing an alternative to the used transducer that could feature equivalent performance and lower cost. In this way, the economical impact of the investment associated to the whole measurement system would be significantly reduced, making the method application much more feasible.

Effetti degli accordi Euro-Mediterrani sul comparto dell'ortofrutta fresca

In 1995, the European Union (EU) Member States and 12 Mediterranean countries launched in Barcelona a liberalization process that aims at establishing a free trade area (to be realized by 2010) and at promoting a sustainable and balanced economic development by the adoption of a new generation of Agreements: the Euro-Mediterranean Agreements (EMA). For the Mediterranean partner countries, the main concern is a better access for their fruit and vegetable exports to the European market. These products represent the main exports of these countries, and the EU is their first trading partner. On the other side, for the EU the main issue is not only the promotion of its products, but also the protection of its fruit and vegetables producers. Moreover, the trade with third countries is the key element of the Common Market Organization of the sector. Fruit and vegetables represent a very sensitive sector since their high seasonality, high perishability, and especially since the production of the Mediterranean countries is often similar to the European Mediterranean’s countries one. In fact, the agreements define preferences at the entrance of the EU market providing limited concessions for each partner, for specific products, limited quantities and calendars. This research tries to analyze the bilateral trade volume for fresh fruit and vegetables in the European and Italian markets in order to assess the effects of Mediterranean liberalization on this sector. Free trade of agricultural products represents a very actual topic in international trade and the Mediterranean countries, recognised as big producers of fruit and vegetables, as big exporters of their crops and actually significantly present on the European market, could be high competitors with the inward production because the outlet could be the same. The goal of this study is to provide some considerations about the competitiveness of mediterranean fruit and vegetables productions after Barcelona Process, in a first step for the European market and then also for the Italian one. The aim is to discuss the influence of the euro-mediterranean agreements on the fruit and vegetables trade between 10 foreign Mediterranean countries (Algeria, Egypt, Israel, Jordan, Libya, Lebanon, Morocco, Tunisia, Syria, and Turkey) and 15 EU countries in the period 1995-2007, by means of a gravity model, which is a widespread methodology in international trade analysis. The basic idea of gravity models is that bilateral trade from one country to another (as the dependent variable) can be explained by a set of factors: - factors that capture the potential of a country to export goods and services; - factors that capture the propensity of a country to imports goods and services; - any other forces that either attract or inhibit bilateral trade. This analysis compares only imports’ flows by Europe and by Italy (in volumes) from Mediterranean countries, since the exports’ flows toward those foreign countries are not significant, especially for Italy. The market of fruit and vegetables appears as a high heterogeneous group so it is very difficult to show a synthesis of the analysis performed and the related results. In fact, this sector includes the so called “poor products” (such as potatoes and legumes), and the “rich product”, such as nuts or exotic fruit, and there are a lot of different goods that arouse a dissimilar consumer demand which directly influence the import requirements. Fruit and vegetables sector includes products with extremely different biological cycles, leading to a very unlike seasonality. Moreover, the Mediterranean area appears as a highly heterogeneous bloc, including countries which differ from the others for economic size, production potential, capability to export and for the relationships with the EU. The econometric estimation includes 68 analyses, 34 of which considering the European import and 34 the Italian import and the products are examined in their aggregated form and in their disaggregated level. The analysis obtains a very high R2 coefficient, which means that the methodology is able to assess the import effects on fruit and vegetables associated to the Association Agreements, preferential tariffs, regional integration, and others information involved in the equation. The empirical analysis suggests that fruits and vegetables trade flows are well explained by some parameters: size of the involved countries (especially GDP and population of the Mediterranean countries); distances; prices of imported products; local production for the aggregated products; preferential expressed tariffs like duty free; sub-regional agreements that enforce the export capability. The euro-mediterranean agreements are significant in some of the performed analysis, confirming the slow and gradual evolution of euro- Mediterranean liberalization. The euro-mediterranean liberalization provides opportunities from one side, and imposes a new important challenge from the other side. For the EU the chance is that fruit and vegetables imported from the mediterranean area represent a support for local supply and a possibility to increase the range of products existing on the market. The challenge regards the competition of foreign products with the local ones since the types of productions are similar and markets coincide, especially in the Italian issue. We need to apply a strategy based not on a trade antagonism, but on the realization of a common plane market with the Mediterranean countries. This goal could be achieved enhancing the industrial cooperation in addition to commercial relationships, and increasing investments’ flows in the Mediterranean countries aiming at transforming those countries from potential competitors to trade partners and creating new commercial policies to export towards extra European countries.

Cooperation and competition in the air transport market: current scenario, possible evolutions and analytical tools

dall'avvento della liberalizzazione, aeroporti e vettori hanno vissuto cambiamenti. Il maggior miglioramneto nella gestione degli aeroporti è una gestione più commerciale ed efficiente. Le forme di regolazione economica e le caratteristiche della gestione manageriale sono state indagate. Dodici paesi sono stati scelti per indagare la situazione del trasporto aereo mondiale, fra questi sia paesi con un sistema maturo sia paesi emergenti. La distribuzione del traffico è stata analizzata con l'indice HHI per evidenziare aeroporti con concentrazione maggiore di 0,25 (in accordo con la normativa statunitense); il sistema aeroportuale è stato analizzato con l'indice di Gini e con l'indice di dominanza. Infine, la teoria dei giochi si è dimostrata un valido supporto per studiare il mercato del trasporto aereo anche con l'uso di giochi di tipo DP

Le società a capitale pubblico locale per i servizi pubblici locali di rilevanza economica: condizioni per la costituzione e il mantenimento, e limiti operativi.

Oggetto della ricerca è l’esame del ruolo attuale della partecipazione pubblica locale in società per l’erogazione di servizi pubblici locali di rilevanza economica, nel nuovo contesto normativo caratterizzato dalla residualità dell’autoproduzione, dalla liberalizzazione, dall’organizzazione del servizio in ambiti territoriali, e dalle esigenze di contenimento della spesa locale, acuite dalla crisi economica-finanziaria. Si sono distinte quattro tipologie di società: nel caso di servizi gestiti in regime di esclusiva, le società a capitale pubblico-privato con socio privato operativo scelto mediante gara, le società in house affidatarie dirette, e le società affidatarie in quanto selezionate in procedure ad evidenza pubblica; nel caso di servizi sottratti al regime di esclusiva, le società che eroghino il servizio liberalizzato. L’indagine si è focalizzata sulle condizioni di costituzione e di mantenimento di tali società, e si è approfondito quel particolare aspetto del loro regime giuridico costituito dai limiti operativi. L’analisi è stata condotta esaminando le nuove disposizioni, le posizioni giurisprudenziali e le letture della dottrina relative alle società disciplinate come forme di gestione di servizi pubblici locali di rilevanza economica, relative alla funzionalizzazione dell’attività degli enti territoriali e delle società da questi partecipate, e relative alla tutela della concorrenza.

I rapporti di collaborazione tra vettori

L’elaborato ha ad oggetto l’analisi delle possibili forme di collaborazione tra vettori nei diversi settori del trasporto, con particolare attenzione all’ambito aeronautico e marittimo. Negli ultimi decenni l’incremento del livello di concorrenza tra i competitors su scala planetaria, a seguito della progressiva liberalizzazione e globalizzazione dei trasporti, ha indotto i vettori ad adottare nuove strategie commerciali dirette alla condivisione del rischio, alla riduzione dei costi di esercizio, all’espansione delle proprie reti e alla flessibilizzazione dei processi interni di adeguamento alle continue espansioni e contrazioni del mercato. Hanno, così, fatto la loro comparsa modelli contrattuali nuovi che differiscono per struttura, livello di integrazione delle parti coinvolte e grado di complessità dell’accordo. Nell’elaborato, pertanto, sono state attentamente esaminate le molteplici figure giuridiche generate dalla prassi commerciale, come gli accordi di codesharing, interlining, wet lease, dry lease, franchising, le grandi alleanze strategiche presenti sia in ambito aeronautico, sia in quello marittimo, le Conferences e i Consorzi. La ricerca, in particolare, è focalizzata, alla luce della prassi contrattuale e della normativa nazionale, comunitaria ed internazionale vigente, sui problemi di qualificazione giuridica di tali accordi e, conseguentemente, sulla disciplina di volta in volta ad essi applicabile, sul loro oggetto, regolamento contrattuale e contenuto. Si è proceduto poi ad uno studio comparativo-contrastivo delle differenze tra le varie forme di partnership e all’approfondimento delle questioni concernenti la tutela degli utenti dei servizi di trasporto, siano essi passeggeri o mittenti. Sono affrontati, infatti, con accurata indagine i profili di responsabilità dei vettori coinvolti, sulla base del quadro normativo di riferimento. Nel corso della ricerca si è data anche particolare attenzione all’analisi della compatibilità degli accordi tra vettori con la disciplina comunitaria della concorrenza, registrando una tendenza della Comunità a piegare l’interpretazione delle norme in materia alle superiori esigenze dell’economia, in considerazione delle peculiarità del mercato del trasporto.

Essays in Environmental Economics

This dissertation comprises four essays on the topic of environmental economics and industrial organization. In the first essay, we develop a two-country world differential game model with a polluting firm in each country to investigate the equilibrium of the game between firms when they decide to trade or not and to see under which conditions social welfare coincides with the market equilibrium. In the second essay, we built a model where firms strategically choose whether to participate in an auction/lottery to attain pollution permits, or instead invest in green R&D, to show that, somewhat counterintuitively, a desirable side effect of the auction is in fact that of fostering environmental R&D in an admissible range of the model parameters. The third essay investigates a second-best trade agreement between two countries when pollution spillovers are asymmetric to examine the strategic behavior of governments in using pollution taxes and tariffs under trade liberalization. The fouth essay studies the profitability of exogenous output constraint in a differential game model with price dynamics under the feedback strategies.

Essays in Industrial Organization

This dissertation comprises four essays on the topic of industrial organization and environmental economics. The first essay investigates the profitability of horizontal mergers of firms with price adjustments. We take a differential game approach and both the open-loop as well as the closed-loop equlibria are considered. In the second essay, using the same approach as the first one, we study the profitability of horizontal merger of firms where the demand function is nonlinear. We take into consideration the open-loop equilibrium. The third essay studies the profitability of exogenous output constraint in a differential game model with price dynamics under the feedback strategies. The fourth essay investigates a second-best trade agreement between two countries when pollution spillovers are asymmetric to examine the strategic behavior of governments in using pollution taxes and tariffs under trade liberalization.
