Állami támogatások és gazdasági teljesítmény. Támogatás-túladagolás a magyar gazdaságfejlesztésben? (An overdose of state aid in the Hungarian economy)

Magyarországon az elmúlt évtizedben a vállalatoknak nyújtott állami támogatás GDP-arányosan számolva az európai uniós átlag 2,7-szerese volt. A cikk megvizsgálja, hogy a támogatások hatása megjelenik-e a magyar gazdaság beruházási, foglalkoztatási, jövedelemtermelési teljesítményében és versenyképességében. Arra a következtetésre jut, hogy egyik területen sem jobb a helyzet, mint azokban az országokban, amelyekben lényegesen alacsonyabb a támogatási arány. A mikroszintű elemzések, értékelések sem támasztják alá azt a vélekedést, hogy az állami támogatások érzékelhetően javítják a gazdasági teljesítményt. A források bősége önmagában is okoz hatékonysági problémákat, mert sok program és szervezet versenyez egymással. A rossz (gyengébb hatékonysági követelményeket támasztó) programok kiszorítják a jó programokat. Ha a versenyképességet érdemben befolyásoló tényezők, például a kedvező jogi szabályozási környezet és az üzleti szolgáltatások jól működő piacai nem adottak, akkor ezek hiányát nem ellensúlyozza a támogatások magas szintje. Magyarország az idén indult hétéves programozási időszakban tovább kívánja növelni a vállalatoknak nyújtott állami támogatások mértékét, miközben nincs egyértelmű válasz arra a kérdésre, hogy milyen módon növelhető a támogatási rendszer jelenleg alacsony hatékonysága. _____ State aid given to enterprises as a proportion of Hungary�s GDP has been 2.7 times the EU average over the past decade. The article examines whether any impact of this high level of state aid can be discerned in investment, employment, income- generation performance, or competitiveness of the Hungarian economy. It seems that in none of these areas is the situation better than in countries that have a markedly lower rate of state aid. Micro-level analyses and evaluations do not support the belief that state aid appreciably improves economic performance. A wealth of resources on its own can cause problems with efficiency, as many programs and organizations compete with each other. Bad (less demanding) programs nudge out the good ones. If the factors significantly determining competitiveness, including a favourable legal and regulatory environment and well-functioning markets of business services, are not in place, a high level of state aid cannot be a proxy for them. In the seven-year programming period beginning this year, Hungary plans to further increase the amount of state aid to enterprises, while there is no clear answer as to how to improve the currently poor efficiency of the state aid system.

The effect of the advanced placement examination for credit policy by the Florida State universities on the acceleration of a student's postsecondary education

The purpose of this research study was to determine if the Advanced Placement program as it is recognized by the universities in the Florida State University System (SUS) truly serves as an acceleration mechanism for those students who enter an SUS institution with passing AP scores. Despite mandates which attempt to control uniformity of policy, each public university in Florida determines which courses will be exempted and the number of credits they will grant for passing Advanced Placement courses.^ This is a descriptive study in which the AP policies of each of the SUS institutions were compared. Additionally, the college attendance and graduation data on members of a cohort of 593 Broward County high school graduates of the class of June, 1992 were compared. Approximately 28% of the cohort members entered university with passing Advanced Placement scores.^ The rate of early and on time graduation was significantly dependent on the Advanced Placement standing of the students in the cohort. Given the financial and human cost involved, it is recommended that all state universities bring their Advanced Placement policies into line with each other and implement a uniform Advanced Placement policy. It is also recommended that a follow-up study be conducted with a new cohort bound under the current 120 credit limitation for graduation. ^

‘State failure’ and the extraterritorial use of force in self-defence against non-state actors

The thesis is first and foremost the examination of the notion and consequences of ‘state failure’ in international law. The disputes surrounding criteria for creation and recognition of states pertain to efforts to analyse legal and factual issues unravelling throughout the continuing existence of states, as best evidenced by the ‘state failure’ phenomenon. It is argued that although the ‘statehood’ of failed states remains uncontested, their sovereignty is increasingly considered to be dependent on the existence of effective governments. The second part of this thesis focuses on the examinations of the legal consequences of the continuing existence of failed states in the context of jus ad bellum. Since the creation of the United Nations the ability of states to resort to armed force without violating what might be considered as the single most important norm of international law, has been considerably limited. State failure and increasing importance of non-state actors has become a greatly topical issue within recent years in both scholarship and the popular imagination. There have been important legal developments within international law, which have provoked much academic, and in particular, legal commentary. On one level, the thesis contributes to this commentary. Despite the fact that the international community continues to perpetuate a notion of ‘statehood’ which allows the state-centric system of international law to exist, when dealing with practical and political realities of state failure, international law may no longer consider external sovereignty of states as an undeniable entitlement to statehood. Accordingly, the main research question of this thesis is whether the implicit and explicit invocation of the state failure provides sufficient legal basis for the intervention in self-defence against non-state actors in located in failed states. It has been argued that state failure has a profound impact, the extent of which is yet to be fully explored, on the modern landscape of peace and security.

Human Herpesvirus-6 And Cytomegalovirus Dna In Liver Donor Biopsies And Their Correlation With Hla Matches And Acute Cellular Rejection.

Herpesvirus reactivation is common after liver transplantation. Analyze the presence of cytomegalovirus (HCMV) and human herpesvirus-6 (HHV-6) DNA in liver donor biopsies, seeking to better understand issues involving human donor leukocyte antigens (HLA)-A, B and DR, as well as correlations with acute cellular rejection. Fifty-nine liver transplantation patients were investigated for the presence of HCMV and HHV-6 DNA in liver donor biopsies, using the Nested-PCR technique. The clinical donor information and HLA matches were obtained from the São Paulo State Transplant System. The recipients' records regarding acute cellular rejection were studied. Seven (11.8%) biopsies were positive for HCMV DNA and 29 (49%) were positive for HHV-6 DNA. In 14 donors with HLA-DR 15 nine had HHV-6 DNA positive liver biopsy with a tendency for significant association (p=0.09), 22 recipients developed acute cellular rejection and 9/22 were positive for HLA-DR 15 (p=0.03; χ(2)=4.51), which was statistically significant in univariate analysis and showed a tendency after multivariate analysis (p=0.08). HHV-6 DNA was prevalent in liver donors studied as well as HLA-DR 15. These findings suggest that patients with HLA-DR 15 in liver donor biopsies develop more rejection after liver transplantation.

Eficácia na utilização de córneas no transplante penetrante

PURPOSES: 1) To verify the impact of the creation of the Single Technical Record (STR) at the University of Campinas (Unicamp) Hospital das Clínicas, on the preservation period of corneas which were used in elective penetrating keratoplasties, and 2) to compare the primary failure incidence in cornea penetrating keratoplasties regarding the periods before and after the creation of STR. METHODS: A retrospective study was conducted at the Unicamp Hospital, which evaluated 15 consecutive cornea penetrating keratoplasties between January 1st and April 30th, 2000 and 24 consecutive penetrating keratoplasties between May 1st and September 20th of the same year (corneas under the control of the STR), totaling 39 keratoplasties. RESULTS: The mean time between cornea preparation and transplantation was 3.8 days (±1.78) in the period before STR creation, and 6.0 days (±2.97) after STR creation, representing a 36.7% increase in the preservation time. There was a statistically significant difference (p=0.02) between the two groups. No corneal primary failure was observed among the 39 transplanted patients in both groups. CONCLUSION: Based on the results of this study, it can be concluded that this new concept of the State Transplantation System has caused a statistically significant increase in the conservation period of corneas, which may reduce the period of a clear transplant due to an increased loss of endothelial cells, as well as increase the primary failure incidence or result in a high number of corneas that cannot be used due to having exceeded the preservation time recommended by the literature.

Práticas educacionais distintas: a psicologia no ensino médio paulista

Este artigo visa discutir, à luz da aprovação do Parecer n. 38/06 do Conselho Nacional de Educação que torna obrigatório o ensino de Filosofia e Sociologia no ensino médio, a pertinência do ensino de Psicologia, em particular no Estado de São Paulo, onde esta disciplina vem progressivamente perdendo espaço. Subsidia o debate, pesquisa de caráter etnográfico, composta por dois estudos de caso realizados em estabelecimentos de ensino, um público e um privado, do município de São Paulo, onde foram acompanhadas aulas de Psicologia mediante observação e analisadas questões relativas ao ensino dessa disciplina. Aspectos característicos de cada escola levaram a refletir sobre as disparidades do sistema educacional paulista, conduzindo à discussão sobre o ensino de Psicologia e sua contribuição, como ciência, nesse cenário.

Áreas de vulnerabilidade para co-infecção HIV-aids/TB em Ribeirão Preto, SP

OBJETIVO: Identificar áreas de vulnerabilidade para os casos novos de co-infecção HIV/tuberculose (TB). MÉTODOS: Estudo descritivo ecológico realizado por meio do georreferenciamento dos casos novos de HIV/TB notificados em Ribeirão Preto, SP, em 2006. Os dados foram obtidos do sistema de informação estadual paulista de notificação de TB. Os casos novos de co-infecção HIV/TB foram analisados conforme características sociodemográficas e clínicas e, posteriormente, georreferenciados na base cartográfica do município segundo endereço residencial. Os setores do município foram categorizados em três níveis socioeconômicos: inferior, intermediário e superior, com base na análise de componentes principais das variáveis do censo demográfico de 2000 (renda, instrução e percentagem de domicílios com cinco ou mais moradores). Foi calculada a incidência da co-infecção HIV/TB para cada nível socioeconômico. RESULTADOS: A co-infecção HIV/TB acometeu mais adultos do sexo masculino em idade economicamente ativa e a forma pulmonar da TB foi a mais comum. A distribuição espacial mostrou que as incidências nas áreas com níveis socioeconômicos intermediários e inferiores (8,3 e 11,5 casos por 100 mil habitantes, respectivamente) foram superiores àquela (4,8 casos por 100 mil habitantes) de nível socioeconômico superior. CONCLUSÕES: A taxa de incidência de co-infecção HIV/TB analisada por níveis socioeconômicos mostrou padraÞo espacial de distribuiçaÞo não homogêneo e apresentou valores mais altos em áreas de maior vulnerabilidade social. O estudo diagnosticou aìreas geograìficas prioritaìrias para o controle da co-infecção e a tecnologia do sistema de informação geográfica pode ser empregada no planejamento das ações em saúde pelos gestores municipais.

Sequential production of amylolytic and lipolytic enzymes by bacterium strain isolated from petroleum contaminated soil

Amylases and lipases are highly demanded industrial enzymes in various sectors such as food, pharmaceuticals, textiles, and detergents. Amylases are of ubiquitous occurrence and hold the maximum market share of enzyme sales. Lipases are the most versatile biocatalyst and bring about a range of bioconversion reactions such as hydrolysis, inter-esterification, esterification, alcoholysis, acidolysis, and aminolysis. The objective of this work was to study the feasibility for amylolitic and lipolytic production using a bacterium strain isolated from petroleum contaminated soil in the same submerged fermentation. This was a sequential process based on starch and vegetable oils feedstocks. Run were performed in batchwise using 2% starch supplemented with suitable nutrients and different vegetable oils as a lipase inducers. Fermentation conditions were pH 5.0; 30 degrees C, and stirred speed (200 rpm). Maxima activities for amyloglucosidase and lipase were, respectively, 0.18 and 1,150 U/ml. These results showed a promising methodology to obtain both enzymes using industrial waste resources containing vegetable oils.

Extraction of manganese peroxidase produced by Lentinula edodes

Lentinula edodes, commonly called shiitake, is considered a choice edible mushroom with exotic taste and medicinal quality. L. edodes grows very well and produces a range of enzymes when cultivated on eucalyptus residues. Development of appropriate experimental procedures for recovery and determination of enzymes became a widely important cash crop. In this work, enzymes produced by L. edodes were extracted using different pH buffer and determined regarding peroxidases and proteases. Lignin peroxidase (LiP) was not detected in the extracts based on veratryl alcohol or azure B oxidation. Proteases were very low while Mn-peroxidases (MnP) predominated. The optimal pH for MnP recovery was 5.0, under agitation at 25 degrees C. The oxidation of phenol red decreased after dark-colored small compounds or ions were eliminated by dialysis. The extract of L. edodes contained components of high molecular weight, such as proteases or high polyphenol, that could be involved in the LiP inactivation. L. edodes sample previously submitted to dialysis was also joined to UP of Phanerochaete chrysosporium and a total inhibition of UP was observed. (C) 2007 Elsevier Ltd. All rights reserved.

Biochemical and Functional Characterization of a Metalloprotease from the Thermophilic Fungus Thermoascus aurantiacus

Protease production was carried out in solid state fermentation. The enzyme was purified through precipitation with ethanol at 72% followed by chromatographies in columns of Sephadex G75 and Sephacryl S100. It was purified 80-fold and exhibited recovery of total activity of 0.4%. SDS-PAGE analysis indicated an estimated molecular mass of 24.5 kDa and the N-terminal sequence of the first 22 residues was APYSGYQCSMQLCLTCALMNCA. Purified protease was only inhibited by EDTA (96.7%) and stimulated by Fe(2+) revealing to be a metalloprotease activated by iron. Optimum pH was 5.5, optimum temperature was 75 degrees C, and it was thermostable at 65 degrees C for 1 h maintaining more than 70% of original activity. Through enzyme kinetic studies, protease better hydrolyzed casein than azocasein. The screening of fluorescence resonance energy transfer (FRET) peptide series derived from Abz-KLXSSKQ-EDDnp revealed that the enzyme exhibited preference for Arg in P(1) (k(cat)/K(m) = 30.1 mM(-1) s(-1)).

Production and characteristics comparison of crude beta-glucosidases produced by microorganisms Thermoascus aurantiacus e Aureobasidium pullulans in agricultural wastes

The purified beta-glucosidase of Aureobasidium pullulans ER-16 is one of more thermostable enzyme reported to date. Considering the unfeasibility of using purified enzyme for industrial application, it was interesting to analyze this property for the crude enzyme. Thermophilic fungus Thermoascus aurantiacus CBMAI-756 and mesophilic A. pullulans ER-16 were cultivated in different hemicellulosic materials on solid-state cultivation for beta-glucosidase production. Wheat bran was most appropriate for beta-glucosidase production by both microorganisms. T. aurantiacus exhibited maximum enzyme production (7.0 U/ml or 70 U/g) at 48-72 h and A. pullulans a maximum (1.3 U/ml or 13 U/g) at 120 h. Maximum activities were at 75 degrees C with optimum pH at 4.5 and 4.0, for T aurantiacus and A. pullulans, respectively. A. pullulans`s beta-glucosidase was more pH stable (4.5-10.0 against 4.5-8.0) and more thermostable (90% after 1 h at 75 degrees C against 85% after 1 h at 70 degrees C) than the enzyme from the thermophilic T. aurantiacus. The t((1/2)) at 80 degrees C were 50 and 12.5 min for A. pullulans and T. aurantiascus, respectively. These data confirm the high thermostability of crude beta-glucosidase from A. pullulans. Both beta-glucosidases were strongly inhibited by glucose, but ethanol significantly increased the activity of the enzyme from T. aurantiacus. (C) 2008 Elsevier Inc. All rights reserved.

Residence time distributions of gas flowing through rotating drum bioreactors

Residence time distribution studies of gas through a rotating drum bioreactor for solid-state fermentation were performed using carbon monoxide as a tracer gas. The exit concentration as a function of time differed considerably from profiles expected for plug flow, plug flow with axial dispersion, and continuous stirred tank reactor (CSTR) models. The data were then fitted by least-squares analysis to mathematical models describing a central plug flow region surrounded by either one dead region (a three-parameter model) or two dead regions (a five-parameter model). Model parameters were the dispersion coefficient in the central plug flow region, the volumes of the dead regions, and the exchange rates between the different regions. The superficial velocity of the gas through the reactor has a large effect on parameter values. Increased superficial velocity tends to decrease dead region volumes, interregion transfer rates, and axial dispersion. The significant deviation from CSTR, plug flow, and plug flow with axial dispersion of the residence time distribution of gas within small-scale reactors can lead to underestimation of the calculation of mass and heat transfer coefficients and hence has implications for reactor design and scaleup.

Evidence of thermostable amylolytic activity from Rhizopus microsporus var. rhizopodiformis using wheat bran and corncob as alternative carbon source

Rhizopus microsporus var. rhizopodiformis produced high levels of alpha-amylase and glucoamylase under solid state fermentation, with several agricultural residues, such as wheat bran, cassava flour, sugar cane bagasse, rice straw, corncob and crushed corncob as carbon sources. These materials were humidified with distilled water, tap water, or saline solutions-Segato Rizzatti (SR), Khanna or Vogel. The best substrate for amylase production was wheat bran with SR saline solution (1:2 v/v). Amylolytic activity was still improved (14.3%) with a mixture of wheat bran, corncob, starch and SR saline solution (1:1:0.3:4.6 w/w/w/v). The optimized culture conditions were initial pH 5, at 45 degrees C during 6 days and relative humidity around 76%. The crude extract exhibited temperature and pH optima around 65 degrees C and 4-5, respectively. Amylase activity was fully stable for 1 h at temperatures up to 75 degrees C, and at pH values between 2.5 and 7.5.

Production of beta-fructofuranosidases by Aspergillus niveus using agroindustrial residues as carbon sources: Characterization of an intracellular enzyme accumulated in the presence of glucose

The production of beta-fructofuranosidases by Aspergillus niveus, cultivated under submerged fermentation using agroindustrial residues, was investigated. The highest productivity of beta-fructofuranosidases was obtained in Khanna medium supplemented with sugar cane bagasse as carbon source. Glucose enhanced the production of the intracellular enzyme, whereas that of the extracellular one was decreased. The intracellular beta-fructofuranosidase was a trimeric protein of approximately 141 kDa (gel filtration) with 53.5% carbohydrate content, composed of 57 kDa monomers (SDS-PAGE). The optimum temperature and optimum pH were 60 degrees C and 4.5, respectively. The purified enzyme showed good thermal stability and exhibited a half-life of 53 min at 60 degrees C. beta-Fructofuranosidase activity was slightly activated by Cu(2+), Mn(2+), Mg(2+), and Na(+) at 1 mM concentration. The enzyme hydrolyzed sucrose, raffinose, and inulin, with K(d) values of 5.78 mM, 5.74 mM, and 1.74 mM, respectively. (C) 2008 Elsevier Ltd. All rights reserved.

Production of fibrolytic enzymes by Aspergillus japonicus C03 using agro-industrial residues with potential application as additives in animal feed

Solid-state fermentation obtained from different and low-cost carbon sources was evaluated to endocellulases and endoxylanases production by Aspergillus japonicus C03. Regarding the enzymatic production the highest levels were observed at 30 degrees C, using soy bran added to crushed corncob or wheat bran added to sugarcane bagasse, humidified with salt solutions, and incubated for 3 days (xylanase) or 6 days (cellulase) with 70% relative humidity. Peptone improved the xylanase and cellulase activities in 12 and 29%, respectively. The optimum temperature corresponded to 60 degrees C and 50-55 degrees C for xylanase and cellulase, respectively, both having 4.0 as optimum pH. Xylanase was fully stable up to 40 degrees C, which is close to the rumen temperature. The enzymes were stable in pH 4.0-7.0. Cu(++) and Mn(++) increased xylanase and cellulase activities by 10 and 64%, respectively. A. japonicus C03 xylanase was greatly stable in goat rumen fluid for 4 h during in vivo and in vitro experiments.
