A dolgozat a politikatudomány és közgazdaság-tudomány határán álló kivonulás-tiltakozás-hűség modell lényegét járja körbe. Az Albert O. Hirschman által felépített gondolati keret szemléleti frissessége és sajátos megközelítési módja rendkívül termékenyítően hatott az elmúlt évtizedekben a társadalomtudományok fejlődésére. Mégis viszonylag periferikus helyet foglal el a közgazdaság-tudományon belül, miközben például a rendszerváltás és az azt követő társadalmi feszültségek megjelenése szempontjából is sokoldalúan használható fogalmi keretről van szó. A válság indukálta turbulens környezet még inkább rávilágít arra, hogy ma is időszerű perspektívát kínál a hanyatlás politikai gazdaságtana, azaz hasznos elemzési kapaszkodó nyújt az úgynevezett Hirschman-trilemma a társadalmi és gazdasági folyamatok értelmezéséhez. ________ The article concerns the "exit, voice, and loyalty" concept, which straddles the border of political science and economics. This theoretical framework, invented by Albert O. Hirschman, has exercised a fruitful influence in the social sciences in the last few decades, through its fresh features and original approach. However, it holds a peripheral position in economics and plays an undervalued role in eco-nomic education in Hungary, even though it can be flexibly applied in analyses of such phenomena as the economic transition and the ensuing social tensions. Moreover the very turbulence of the conditions brought about by the crisis show that the political economy of decline offers a relevant perspective, so that the Hirschman trilemma is a practical analytical tool for understanding social and economic processes.

Tanulmányunkban az Albert 0. Hirschman által kialakított „kivonulás, tiltakozás, hűség” koncepció metaelméleti felhasználásával a „kapitalizmus változatai” elméletet vesszük bírálat alá. Egyrészt arra mutatunk rá, hogy már a különböző piacgazdasági modellek tipologizálásához használt vállalatelméleti dimenziójú elemzések is építkeznek a Hirschman-trilemmából, másrészt arra hívjuk fel a figyelmet, hogy olyan sajátos eszközről van szó, amely a tőke- és munkaerő-piaci folyamatok elemzésére támaszkodva új perspektívát is kínál a kapitalista gazdaságok komparatív vizsgálatához. A dolgozat terjedelmi okokból az empirikus kutatásokat megalapozó elméleti alapozásra szorítkozik. ____ In our study we deal with the critical analysis of the “varieties of capitalism” theory by using the “exit, voice, and loyalty” meta-theory invented by Albert O. Hirschman. The paper emphasizes that on the one hand the analyses of the theory of the firm and business used for the classification of distinct market models are also building upon the “Hirschman trilemma”, and on the other hand, it draws attention to the fact that the Hirschmanian method based on labor market and capital market offers a new perspective for the comparative analysis of capitalist economies. The focus of the article is only the theoretical foundation of empirical studies as a result of limitation of scope.

This study explores two important aspects of entrepreneurship — liquidity constraints and serial entrepreneurs, with an additional analysis of occupational choice among wage workers. In the first essay, I revisit the question of whether entrepreneurs face liquidity constraints in business formation. The principle challenge is that wealth is correlated with unobserved ability, and adequate instruments are often difficult to identify. This paper uses the son's birth order as an instrument for household wealth. I exploit the data available in the Korean Labor and Income Panel Study, and find evidence of liquidity constraints associated with self-employment in South Korea. The second essay develops and tests a model that explains entry into serial entrepreneurship and the performance of serial entrepreneurs as the result of selection on innate ability. The model supposes that agents establish businesses with imperfect information about their entrepreneurial ability and the profitability of business ideas. Agents continually observe signals with which they update their beliefs, and this process eventually determines their next business choice. Selection on ability induces a positive correlation between entrepreneurial experience (measured by previous business earnings and founding experience) and serial business formation, as well as its subsequent performance. The predictions in the model are tested using panel data from the NLSY79. The analysis permits a distinction to be made between selection on innate ability and learning by doing. Motivated by previous empirical findings that white-collar workers had higher turnover rates than blue-collar workers during firm expansion, the third essay further examines job turnover among workers with or without specific skills. I present a search-matching model, which predicts that when firm growth is driven by technological advance, workers whose skills are specific to the obsolete technology show a higher tendency to separate from their jobs. This hypothesis is tested with data from the PSID. I find supportive evidence that in the context of technological change, having an occupation requiring specific skills, such as computer specialists or engineers, increases the odds of job separation by nearly eight percent. ^

This study investigated the effects of two types of bilingual education programs (two-way and transitional) on the academic performance, attitudes, and metacognitive awareness of 5th grade students who entered kindergarten or first grade with different levels of English proficiency. The multi-stage sample consisted of students who had participated in each program for a period of at least five years. A mixed model design allowed for the collection of quantitative and qualitative data that were analyzed accordingly and integrated. ^ The findings indicated no significant differences between the two groups on measures of academic achievement in English. Significant differences were found in the number of semesters required for the students to become proficient English speakers. An important conclusion, based on these findings, was that the students enrolled in the two-way bilingual education (TWBE) programs learned English faster. Moreover, they maintained a high level of proficiency in Spanish, scoring significantly higher than the transitional bilingual education group on measures of Spanish reading ability.^ Questionnaire and interview data indicated that the students in the two-way bilingual education programs tended to use more Spanish for recreational purposes and tended to rate themselves as more proficient Spanish speakers than their peers. Conversely, the students enrolled in the transitional bilingual education programs tended to rate themselves as more proficient in English than their peers. ^ The level of English language proficiency upon entering school (five years later) was found to make a difference in academic achievement, as measured by standardized tests. Five years of schooling did not fully eliminate the gap in academic performance between students with different ESOL entry levels at kindergarten. However, entry level did not have an effect on attitudes towards bilingualism. ^ It is concluded that, although there was no significant difference between the two groups on measures of academic achievement in English, TWBE and transitional programs have differential effects. Students in the TWBE programs acquired oral language at a faster rate, developed literacy skills in their native language, and acquired more positive attitudes towards bilingualism. Theoretical, methodological, and policy implications of the findings are discussed. ^

Organizations of the Social Economy in Spain accounted for 13% of employment and 12% of GDP in 2013, according to the Spanish Confederation fo Social Economy. Also, according to various institutions and studies, the role of Social Economy has become relevant due to they represent a model promoting the creation of collective business projects with greater sustainability and potential than models of individual self-employment. However, despite all this, there are few academic studies or sectoral reports analyzing employment in this sector, especially in the case of youth employment. This study aims to fill this gap in the literature analyzing the scared available data in order to show the numbers and characteristics of youth employment in this sector. Results show the weight of youth employment in the Social Economy is higher than the economy overall.

Following the intrinsically linked balance sheets in his Capital Formation Life Cycle, Lukas M. Stahl explains with his Triple A Model of Accounting, Allocation and Accountability the stages of the Capital Formation process from FIAT to EXIT. Based on the theoretical foundations of legal risk laid by the International Bar Association with the help of Roger McCormick and legal scholars such as Joanna Benjamin, Matthew Whalley and Tobias Mahler, and founded on the basis of Wesley Hohfeld’s category theory of jural relations, Stahl develops his mutually exclusive Four Determinants of Legal Risk of Law, Lack of Right, Liability and Limitation. Those Four Determinants of Legal Risk allow us to apply, assess, and precisely describe the respective legal risk at all stages of the Capital Formation Life Cycle as demonstrated in case studies of nine industry verticals of the proposed and currently negotiated Transatlantic Trade and Investment Partnership between the United States of America and the European Union, TTIP, as well as in the case of the often cited financing relation between the United States and the People’s Republic of China. Having established the Four Determinants of Legal Risk and its application to the Capital Formation Life Cycle, Stahl then explores the theoretical foundations of capital formation, their historical basis in classical and neo-classical economics and its forefathers such as The Austrians around Eugen von Boehm-Bawerk, Ludwig von Mises and Friedrich von Hayek and most notably and controversial, Karl Marx, and their impact on today’s exponential expansion of capital formation. Starting off with the first pillar of his Triple A Model, Accounting, Stahl then moves on to explain the Three Factors of Capital Formation, Man, Machines and Money and shows how “value-added” is created with respect to the non-monetary capital factors of human resources and industrial production. Followed by a detailed analysis discussing the roles of the Three Actors of Monetary Capital Formation, Central Banks, Commercial Banks and Citizens Stahl readily dismisses a number of myths regarding the creation of money providing in-depth insight into the workings of monetary policy makers, their institutions and ultimate beneficiaries, the corporate and consumer citizens. In his second pillar, Allocation, Stahl continues his analysis of the balance sheets of the Capital Formation Life Cycle by discussing the role of The Five Key Accounts of Monetary Capital Formation, the Sovereign, Financial, Corporate, Private and International account of Monetary Capital Formation and the associated legal risks in the allocation of capital pursuant to his Four Determinants of Legal Risk. In his third pillar, Accountability, Stahl discusses the ever recurring Crisis-Reaction-Acceleration-Sequence-History, in short: CRASH, since the beginning of the millennium starting with the dot-com crash at the turn of the millennium, followed seven years later by the financial crisis of 2008 and the dislocations in the global economy we are facing another seven years later today in 2015 with several sordid debt restructurings under way and hundred thousands of refugees on the way caused by war and increasing inequality. Together with the regulatory reactions they have caused in the form of so-called landmark legislation such as the Sarbanes-Oxley Act of 2002, the Dodd-Frank Act of 2010, the JOBS Act of 2012 or the introduction of the Basel Accords, Basel II in 2004 and III in 2010, the European Financial Stability Facility of 2010, the European Stability Mechanism of 2012 and the European Banking Union of 2013, Stahl analyses the acceleration in size and scope of crises that appears to find often seemingly helpless bureaucratic responses, the inherent legal risks and the complete lack of accountability on part of those responsible. Stahl argues that the order of the day requires to address the root cause of the problems in the form of two fundamental design defects of our Global Economic Order, namely our monetary and judicial order. Inspired by a 1933 plan of nine University of Chicago economists abolishing the fractional reserve system, he proposes the introduction of Sovereign Money as a prerequisite to void misallocations by way of judicial order in the course of domestic and transnational insolvency proceedings including the restructuring of sovereign debt throughout the entire monetary system back to its origin without causing domino effects of banking collapses and failed financial institutions. In recognizing Austrian-American economist Schumpeter’s Concept of Creative Destruction, as a process of industrial mutation that incessantly revolutionizes the economic structure from within, incessantly destroying the old one, incessantly creating a new one, Stahl responds to Schumpeter’s economic chemotherapy with his Concept of Equitable Default mimicking an immunotherapy that strengthens the corpus economicus own immune system by providing for the judicial authority to terminate precisely those misallocations that have proven malignant causing default perusing the century old common law concept of equity that allows for the equitable reformation, rescission or restitution of contract by way of judicial order. Following a review of the proposed mechanisms of transnational dispute resolution and current court systems with transnational jurisdiction, Stahl advocates as a first step in order to complete the Capital Formation Life Cycle from FIAT, the creation of money by way of credit, to EXIT, the termination of money by way of judicial order, the institution of a Transatlantic Trade and Investment Court constituted by a panel of judges from the U.S. Court of International Trade and the European Court of Justice by following the model of the EFTA Court of the European Free Trade Association. Since the first time his proposal has been made public in June of 2014 after being discussed in academic circles since 2011, his or similar proposals have found numerous public supporters. Most notably, the former Vice President of the European Parliament, David Martin, has tabled an amendment in June 2015 in the course of the negotiations on TTIP calling for an independent judicial body and the Member of the European Commission, Cecilia Malmström, has presented her proposal of an International Investment Court on September 16, 2015. Stahl concludes, that for the first time in the history of our generation it appears that there is a real opportunity for reform of our Global Economic Order by curing the two fundamental design defects of our monetary order and judicial order with the abolition of the fractional reserve system and the introduction of Sovereign Money and the institution of a democratically elected Transatlantic Trade and Investment Court that commensurate with its jurisdiction extending to cases concerning the Transatlantic Trade and Investment Partnership may complete the Capital Formation Life Cycle resolving cases of default with the transnational judicial authority for terminal resolution of misallocations in a New Global Economic Order without the ensuing dangers of systemic collapse from FIAT to EXIT.

Résumé : La variation de la [Ca2+] intracellulaire participe à nombreux de processus biologiques. Les cellules eucaryotes expriment à la membrane plasmique une variété de canaux par lesquelles le calcium peut entrer. Dans les cellules non excitables, deux mécanismes principaux permettent l'entrée calcique; l'entrée capacitative de Ca2+ via Orai1 (SOCE) et l'entrée calcique activé par un récepteur (ROCE). Plusieurs protéines clés sont impliquées dans la régulation de ces voies d'entrée calcique, ainsi que dans l'homéostasie calcique. TRPC6 est un canal calcique impliquée dans l'entrée calcique dans les cellules à la suite d’une stimulation d’un récepteur hormonal. TRPC6 transloque à la membrane cellulaire et il y demeure jusqu'à ce que le stimulus soit retiré. Les mécanismes qui régulent le trafic et l'activation de TRPC6 sont cependant encore peu connus. Des découvertes récentes ont démontré qu'il y a un rôle potentiel de Rho kinase dans l'activité de TRPC6. Rho kinase est activée par la petite protéine G RhoA qui peut être activée par les protéines G hétérotrimériques Gα12 et Gα13. En plus de Gα12 et Gα13, les protéines de désensibilisation des GPCR β -arrestin 1 et / ou β-arrestin 2 peuvent aussi activer RhoA. Le but de notre étude est d'examiner la participation des protéines Gα12/13 et β-arrestin 1/ β-arrestin 2 dans l'activation de TRPC6 et de la protéine Orai1. Nous avons utilisé des ARN interférant (siRNA) spécifiques pour induire une réduction de l'expression de Gα12/13 ou β-arrestin 1/β-arrestin 2. La conséquence sur l’entrée de Ca2+ dans les cellules a été ensuite déterminée par imagerie calcique en temps réel suite à une stimulation par la vasopressine (AVP), thapsigargin ou carbachol. Nous avons donc identifié que dans des cellules A7r5, une lignée cellulaire de musculaires lisses vasculaires où le canal TRPC6 exprimé de manière endogène, la diminution de l’expression des protéines Gα12 ou Gα13 ne semble pas modifier l’entrée Ca2+ induit par l’AVP par rapport aux cellules témoins. D'autre part, la diminution de l’expression β-arrestin 1 ou β-arrestin 2 dans des cellules HEK 293 ainsi que des cellules HEK 293 exprimant de façon stable TRPC6 (cellules T6.11) ont augmenté l’entrée de Ca2+ induite par thapsigargin, un activateur pharmacologique de SOCE. Des études de co-immunoprécipitation démontrent une interaction entre la β-arrestin 1 et STIM1, alors qu'aucune interaction n'a été observée entre les β-arrestin 1 et Orai1. Nous avons de plus montré à l'aide d'analyse en microscopie confocale que la diminution de l’expression β-arrestin 1 ou β-arrestin 2 n’influence pas la quantité d’Orai1 à la périphérie cellulaire. Cependant, des résultats préliminaires indiquent que la diminution de l’expression β-arrestin 1 ou β-arrestin 2 augmente la quantité de STIM1-YFP dans l'espace intracellulaire et diminue sa quantité à la périphérie cellulaire. En conclusion, nous avons montré que les β-arrestin 1 ou β-arrestin 2 sont impliquées dans l'entrée capacitative de Ca2+ (SOCE) et contrôlent la quantité de STIM1 dans le réticulum endoplasmique.

Statewide exit exams are often believed to have a positive impact on school effectiveness and the alignment between instructional practice and state standards because of their mandatory nature and the stakes attached for students and teachers. They may also, however, lead to teaching to the test and to a perceived de-professionalization of the teaching role. While some studies suggest a narrowing of contents and an increase in teacher-centered instruction, little is known about how the impact on instructional practices and teacher cognitions varies between different exam systems. This study compares the strategies teachers use to prepare their students for the exams at the end of upper secondary education in Finland, Ireland, and the Netherlands using a standardized questionnaire survey with responses from 385 teachers. The goal was to develop hypotheses about the relationship between differences in the exam procedures and the stakes attached, and the differences in teacher preparation strategies. The results suggest country-specific variations regarding teacher beliefs as to how much time should be spent on exam preparation; however, there were smaller differences in the strategies applied. Regression analyses indicated that the way in which preparation intensity was associated with the stakes for students and schools, and the attitudes towards the exams themselves varied across the three countries. The different exam systems appeared to affect preparation in markedly different ways, but nevertheless led to the exercise of comparable strategies. (DIPF/Orig.)

Hydrocephalus has been known to affect humans since the birth of human medicine as it is described by Hippocrates. The management of this condition is however still dodged by challenges due to a poor understanding of its pathophysiology. The ventriculoperitoneal shunt presents considerable problems especially with respect to infection and shunt malfunction. Low income countries, that currently face the greater burden of paediatric hydrocephalus. experience an increased challenge with ventriculoperitoneal shunts due to a shortage of qualified personnel to handle shunt complications. Recent advances in neuro-endoscopic surgery have presented opportunities for alternative treatment options for hydrocephalus such as endoscopic third ventriculostomy (ETV). This paper explores the alternative views in the pathophysiology of hydrocephalus and how they explain the effectiveness of ETV in treating hydrocephalus arising from a variety of causes.

Over the past 15 years, the number of international development projects aimed at combating global poverty has increased significantly. Within the water and sanitation sector however, and despite heightened global attention and an increase in the number of infrastructure projects, over 800 million people remain without access to appropriate water and sanitation facilities. The majority of donor aid in the water supply and sanitation sector of developing countries is delivered through standalone projects. The quality of projects at the design and preparation stage is a critical determinant in meeting project objectives. The quality of projects at early stage of design, widely referred to as quality at entry (QAE), however remains unquantified and largely subjective. This research argues that water and sanitation infrastructure projects in the developing world tend to be designed in the absence of a specific set of actions that ensure high QAE, and consequently have relatively high rates of failure. This research analyzes 32 cases of water and sanitation infrastructure projects implemented with partial or full World Bank financing globally from 2000 – 2010. The research uses categorical data analysis, regression analysis and descriptive analysis to examine perceived linkages between project QAE and project development outcomes and determines which upstream project design factors are likely to impact the QAE of international development projects in water supply and sanitation. The research proposes a number of specific design stage actions that can be incorporated into the formal review process of water and sanitation projects financed by the World Bank or other international development partners.

This thesis is an interdisciplinary piece of academic research, situated within Critical Theory but engaging with other disciplines, mainly Political Economy and Politics, to tackle the topic at hand; sovereign debt crises. The thesis deals with the Problem of Debt and, more specifically, the Problem of Prolonged Sovereign Debt Crises, which is described in this thesis as the phenomenon of the “Debt Trap”. The specific question that will occupy us in this thesis is why countries appear unable to exit these prolonged debt crises. By exiting a debt crisis, we mean here a state of affairs in which a country has managed to render its debt sustainable, regain its democratic sovereignty, achieve economic recovery and, what is more, mitigate adverse effects of the crisis, especially in what human development, social inequality and poverty rates are concerned. This question is tackled through the use of an interdisciplinary approach that combines critical theory perspectives -which are grouped in two paradigms, the Subjectivity paradigm and the genealogies of Capitalism paradigm- with financialisation literature. The purpose is to form an interdisciplinary intellectual framework that will allow us to analyse with a critical perspective the two case studies of the Greek crisis from 2009 to 2015 and the Argentinean crisis from 1983 to 2005. The aim of the thesis is to develop a theoretical framework that allows us to deconstruct the various ideological approaches to these two particular cases of Debt traps, including neoclassical and neoliberal approaches, Conservative and Keynesian approaches and uncover the political, economic and class relation that underpin the prolonged crises that the two countries have experienced.

To evaluate whether dyspareunia is associated with HIV status in menopausal women and also to assess which factors are associated with dyspareunia in a group of HIV-positive menopausal women. A cross-sectional study was conducted with 178 HIV-negative and 128 HIV-positive women aged 40-60 years. The Short Personal Experiences Questionnaire (SPEQ) was used to collect data. Sociodemographic, clinical, behavioural and reproductive factors were evaluated, as well as factors related to the HIV infection. Dyspareunia was defined as pain during intercourse. A bivariate analysis and Poisson multiple regression analysis were performed. Overall, 41.4% of the HIV-positive women reported dyspareunia compared with 34.8% of the HIV-negative women (p=0.242). In the HIV-positive women, bivariate analysis revealed an association between dyspareunia and having a steady partner (p=0.047); the woman's partner having undergone HIV testing (p=0.020); vaginal dryness (p<0.001); muscle/joint pain (p=0.021); physical/emotional violence (p=0.049); urinary incontinence (p=0.004); and the use of lamivudine/zidovudine (p=0.048). The Poisson multiple regression analysis found an association between dyspareunia and vaginal dryness (prevalence ratio (PR)=1.96, 95% CI 1.10 to 3.50, p=0.023) and urinary incontinence (PR=1.86, 95% CI 1.06 to 3.27, p=0.031). Dyspareunia was common in this group of HIV-positive women and was associated principally with vaginal dryness and urinary incontinence. The importance of treating dyspareunia within the context of sexual health in this group of women should be emphasised and appropriate management of this issue may reduce the likelihood of lesions on the vaginal wall, which may act as a portal of entry for other infections.
