Hungarian Agriculture at the Dawn of EU Accession

EUROCHOICES, Issue 1 2004
Imre Nemeth
Summary Hungarian AgricuIture at the Dawn of EU Accession Hungary and Hungarian agriculture nurse high hopes for EU-accession. Agriculture and rural development were of pivotal importance during the accession negotiations, in the accession referendum and the preparations for accession. The success in integrating our agriculture into the CAP and the single market will substantially influence public opinion in the post-accession years. We expect our membership to stabilise market conditions and to improve development possibilities in rural areas where there is great demand for better employment and living conditions. These benefits will emerge from our integration into the single market, our involvement in decision-making and from the backing of EU resources. But the challenges of EU membership also evoke fears amongst Hungarian farmers. The transformation of agriculture is incomplete, agricultural incomes and investments are stagnant, rural infrastructure is somewhat weak and marketing systems are rather inefficient. Hungarian farmers have difficulty accepting the relatively low levels of direct aids whereas they face full health and food safety restrictions from day one of accession. The CAP Reform of June 2003 confuses and slows down our preparatory work. Hungarian agriculture, however, is determined to respond to the challenges of accession. Our common Europe will prove stronger with Hungarian agriculture, and Hungarian agriculture has to become stronger through our EU membership. L'agriculture hongroise au temps zéro de I'accession OLa Hongrie et l'agriculture hongroise mettent de grands espoirs dans L'accession à l'Union Européenne. L'agriculture et le développement rural ont été au centre des négotiations sur l'accession, du référendum associé et des mesures préparatoires correspondantes. l'opinion publique sera grandement influenceée, dans les années qui suivront l'accession, par le succés de l'intégration de notre agriculture dans la politique agricole commune et le marché unique. De notre appartenance à l'UE, nous attendons la stabilisation des marchés et l'amélioration des perspectives de développement dans les zones rurales oú le besoin de meilleures conditions de vie et d'emploi se fait sentir avec acuité. Ces avantages devraient provenir de notre intégration dans le marché unique, de notre participation aux décisions collectives et d'un soutien à la mesure des ressources de l'Union Européenne. Cependant, les défis de l'intégration européenne ne vont pas aussi sans susciter des craintes chez les agriculteurs hongrois. La transformation de l'agriculture est incompléte, les revenus et les investissements stagnent, les infrastructures rurales sont insuffisantes et l'organisation des marchés inefficace. Les agriculteurs hongrois acceptent difficilement de ne bénéficier que d'aides directes relativement faibles, alors que, dés le premier jour de l'accession, ils seront soumis à tous les réglements communautaires en matiére de santé et de sécurité alimentaires. La réforme de la PAC en juin 2003 complique encore et ralentit les travaux préparatoires à l'accession. Néanmoins, l'agriculture hongroise est résolue à relever le défi. L'Europe commune sera plus forte avec l'agriculture hongroise et cette derniére sera renforcée par son appartenance à l' Europe Ungarische Landwirtschaft kurz vor dem EU-Beitritt Ungarn und die ungarische Landwirtschaft setzen große Hoffnungen in den EU-Beitritt. Die Landwirtschaft und die Entwicklung des ländlichen Raums waren in den Beitrittsverhandlungen, beim Volksentscheid zum Beitritt und bei den Vorbereitungen des Beitritts von entscheidender Bedeutung. Das Gelingen bei der Integration unserer Landwirtschaft in die GAP und den Binnenmarkt wird die öffendiche Meinung in den Jahren nach dem Beitritt entscheidend beeinflussen. Wir erhoffen uns von unserer Mitgliedschaft stabilere Marktbedingungen und bessere Entwicklungsmöglichkeiten im ländlichen Raum, wo Verbesserungen im Hinblick auf Beschäftigungssituation und Lebensbedingungen dringend erforderlich sind. Dies wird durch unsere Integration in den Binnenmarkt, unseren Beitrag zur Entscheidungsfindung und mit Hilfe von EU-Ressourcen erfolgen. Die Herausforderungen der EU-Mitgliedschaft rufen jedoch bei den ungarischen Landwirten auch Ängste hervor. Die Transformation der Landwirtschaft ist noch nicht abgeschlossen, die ländwirtschaftlichen Einkommen und die Investitionen stagnieren, die landliche Infrastruktur ist recht schwach entwickelt und die Vermarktung ist relativ ineffizient. Die ungarischen Landwirte können nur schwer akzeptieren, dass ab dem ersten Tag ihres Beitritts zwar alle Gesundheits- und Nahrungs-mittelsicherheitsbestimmunge n eingehalten werden müssen, aber nur geringe direkte Beihilfen gewährt werden. Die Reform der GAP vom Juni 2003 irritiert und verzögert unsere Vorbereitungen. Die ungarische Landwirtschaft ist jedoch entschlossen, sich den Herausforderungen des Beitritts zu stellen. Unser gemeinsames Europa wird mit der ungarischen Landwirtschaft noch stärker, und die ungarische Landwirtschaft muss durch unsere EU-Mitgliedschaft gestärkt werden. [source]

Experimental research of pool boiling heat transfer in horizontal narrow spaces

HEAT TRANSFER - ASIAN RESEARCH (FORMERLY HEAT TRANSFER-JAPANESE RESEARCH), Issue 5 2004
Enshen Long
Abstract Much progress has been made in high-performance electronic chips, the miniaturization of electronic circuits and other compact systems recently, which brings about a great demand for developing efficient heat removal techniques to accommodate these high heat fluxes. With this objective in mind, experiments were carried out on five kinds of test elements with distilled water and ethanol as working liquids. The test elements used in these experiments consisted of five parallel discs with diameters varying from 5 mm to 40 mm. The experiments were performed with the discs oriented horizontally and uniform heat fluxes applied at the bottom surfaces. The influence of narrow spacing, space size, working liquid property, and heat flux on boiling heat transfer performance in narrow spaces has been investigated. Experimental results showed that the boiling heat transfer coefficient of a narrow space was 3 to 6 times higher than that of pool boiling when the narrow space size and heat flux combine adequately, but the critical heat flux was lower than that of pool boiling. © 2004 Wiley Periodicals, Inc.

A terminal-controlled vertical handover decision scheme in IEEE 802.21-enabled heterogeneous wireless networks

INTERNATIONAL JOURNAL OF COMMUNICATION SYSTEMS, Issue 7 2009
Jung-Shyr Wu
Abstract The seamless internetworking among heterogeneous networks is in great demand to provide ,always-on' connectivity services with quality of service (QoS) provision, anywhere at anytime. The integration of wireless-fidelity (Wi-Fi) and wireless metropolitan area networks (WiMAX) networks can combine their best features to provide ubiquitous access, while mediating the weakness of both networks. While it is challenging to obtain optimized handover decision-based dynamic QoS information, users can improve their perceived QoS by using the terminal-controlled handover decision in a single device equipped with multiple radio interfaces. The IEEE 802.21 aims at providing a framework that defines media-independent handover (MIH) mechanism that supports seamless handover across heterogeneous networks. In this paper, an multiple attributes decision making-based terminal-controlled vertical handover decision scheme using MIH services is proposed in the integrated Wi-Fi and WiMAX networks to provide ,always-on' connectivity QoS services. The simulation results show that the proposed scheme provides smaller handover times and lower dropping rate than the RSS-based and cost function-based vertical handover schemes.

International political marketing: a case study of United States soft power and public diplomacy

JOURNAL OF PUBLIC AFFAIRS, Issue 3 2008
Henry H. Sun
Political marketing can be categorized with three aspects: the election campaign as the origin of political marketing, the permanent campaign as a governing tool and international political marketing (IPM) which covers the areas of public diplomacy, marketing of nations, international political communication, national image, soft power and the cross-cultural studies of political marketing. IPM and the application of soft power have been practiced by nation-states throughout the modern history of international relations starting with the signing of the Treaty of Westphalia in 1648. Nation-states promote the image of their country worldwide through public diplomacy, exchange mutual interests in their bilateral or multilateral relation with other countries, lobby for their national interests in international organizations and apply cultural and political communication strategies internationally to build up their soft power. In modern international relations, nation-states achieve their foreign policy goals by applying both hard power and soft power. Public diplomacy as part of IPM is a method in the creation of soft power, as well as, in the application of soft power. This paper starts with the definitional and conceptual review of political marketing. For the first time in publication, it establishes a theoretical model which provides a framework of the three aspects of political marketing, that is electoral political marketing (EPM), governmental political marketing (GPM) and IPM. This model covers all the main political exchanges among six inter-related components in the three pairs of political exchange process, that is candidates and party versus voters and interest groups in EPM ; governments, leaders and public servants versus citizens and interest groups in GPM, including political public relations and lobbying which have been categorized as the third aspect of political marketing in some related studies; and governments, interest group and activists versus international organizations and foreign subjects in IPM. This study further develops a model of IPM, which covers its strategy and marketing mix on the secondary level of the general political marketing model, and then, the third level model of international political choice behaviour based the theory of political choice behaviour in EPM. This paper continues to review the concepts of soft power and public diplomacy and defines their relation with IPM. It then reports a case study on the soft power and public diplomacy of the United States from the perspectives of applying IPM and soft power. Under the framework of IPM, it looks at the traditional principles of US foreign policy, that is Hamiltonians, Wilsonians, Jeffersonians and Jacksonians, and the application of US soft power in the Iraq War since 2003. The paper advances the argument that generally all nation states apply IPM to increase their soft power. The decline of US soft power is caused mainly by its foreign policy. The unilateralism Jacksonians and realism Hamiltonians have a historical trend to emphasize hard power while neglecting soft power. Numerous reports and studies have been conducted on the pros and cons of US foreign policy in the Iraq War, which are not the focus of this paper. From the aspect of IPM, this paper studies the case of US soft power and public diplomacy, and their effects in the Iraq War. It attempts to exam the application of US public diplomacy with the key concept of political exchange, political choice behaviour, the long-term approach and the non-government operation principles of public diplomacy which is a part of IPM. The case study confirms the relations among IPM, soft power and public diplomacy and finds that lessons can be learned from these practices of IPM. The paper concludes that there is a great demand for research both at a theoretical as well as practical level for IPM and soft power. It calls for further study on this subject.

International political marketing: a case study of its application in China

JOURNAL OF PUBLIC AFFAIRS, Issue 4 2007
Henry H. Sun
The practice of International Political Marketing can be seen increasingly in the foreign relations of independent states. A review of relevant Political Marketing and International Relations publications reveals close linkage between the two. Based on the review, this paper categorizes political marketing into three aspects: the election aspect, the governing aspect (permanent campaign) and the international aspect of political marketing. The focus of this study is on international political marketing which was defined based on the review. This paper then reports a case study of the utilization of International Political Marketing by the government of the People's Republic of China. It looks at the recent events of China's accession of the WTO in 2001, China's hosting of Sino-African Summit in 2006 and the on going promotion of China's image of ,Peaceful Development and Cooperation'. The paper advances the argument that practically all nation states and international organizations apply International Political Marketing to both their strategic planning as well as conduct of day-to-day affairs. The paper concludes that there is a great demand both at a theoretical as well as practical level for International Political Marketing, requiring further study.

Production of ,-Galactosyl Epitopes via Combined Use of Two Recombinant Whole Cells Harboring UDP-Galactose 4-Epimerase and ,-1,3-Galactosyltransferase

BIOTECHNOLOGY PROGRESS, Issue 4 2000
Xi Chen
,-Galactosyl epitopes (or ,-Gal, oligosaccharides with a terminal Gal,1,3Gal sequence) are a class of biologically important oligosaccharides in great demand in bulk quantities for basic and clinical studies on preventing hyperacute rejection in pig-to-primate organ xenotransplantaion. A truncated bovine ,-1,3-galactosyltransferase, the key enzyme responsible for the biosynthesis of the terminal structure of ,-Gal, was cloned and overexpressed previously. The acceptor specificity was further studied in the present paper, and lactose and galactose derivatives were found to be good acceptors. To develop a more proficient reaction process, we report herein an example of an efficient enzymatic synthesis of ,-Gal oligosaccharides catalyzed by the combination of two recombinant Escherichia coli whole cells harboring the genes of a UDP-galactose 4-epimerase and the ,-1,3-galactosyltransferase, respectively. Using lactosyl azide (LacN3) as the acceptor for the glycosyltransferase, the combined use of the two recombinant cells efficiently produced ,-Gal epitope Gal,1,3LacN3 in 60,68% yield. [source]

Specific Labeling of Peptidoglycan Precursors as a Tool for Bacterial Cell Wall Studies

CHEMBIOCHEM, Issue 4 2009
Vincent van Dam
Abstract Wall chart: The predominant component of the bacterial cell wall, peptidoglycan, consists of long alternating stretches of aminosugar subunits interlinked in a large three-dimensional network and is formed from precursors through several cytosolic and membrane-bound steps. The high tolerance of the cell wall synthesis machinery allows for the use of labeled precursor derivatives to study diverse aspects of bacterial cell wall synthesis and interaction with antibiotics. Because of its importance for bacterial cell survival, the bacterial cell wall is an attractive target for new antibiotics in a time of great demand for new antibiotic compounds. Therefore, more knowledge about the diverse processes related to bacterial cell wall synthesis is needed. The cell wall is located on the exterior of the cell and consists mainly of peptidoglycan, a large macromolecule built up from a three-dimensional network of aminosugar strands interlinked with peptide bridges. The subunits of peptidoglycan are synthesized inside the cell before they are transported to the exterior in order to be incorporated into the growing peptidoglycan. The high flexibility of the cell wall synthesis machinery towards unnatural derivatives of these subunits enables research on the bacterial cell wall using labeled compounds. This review highlights the high potential of labeled cell wall precursors in various areas of cell wall research. Labeled precursors can be used in investigating direct cell wall,antibiotic interactions and in cell wall synthesis and localization studies. Moreover, these compounds can provide a powerful tool in the elucidation of the cell wall proteome, the "wallosome," and thus, might provide new targets for antibiotics. [source]

Not all roads lead to Rome,a review of quality of life measurement in adults with diabetes

DIABETIC MEDICINE, Issue 4 2009
J. Speight
Abstract Aims Quality of life (QoL) is recognized widely as an important health outcome in diabetes, where the burden of self-management places great demands on the individual. However, the concept of QoL remains ambiguous and poorly defined. The aim of our review is to clarify the measurement of QoL in terms of conceptualization, terminology and psychometric properties, to review the instruments that have been used most frequently to assess QoL in diabetes research and make recommendations for how to select measures appropriately. Methods A systematic literature search was conducted to identify the ten measures most frequently used to assess QoL in diabetes research (including clinical trials) from 1995 to March 2008. Results Six thousand and eight-five abstracts were identified and screened for instrument names. Of the ten instruments most frequently used to assess ,QoL', only three actually do so [i.e. the generic World Health Organization Quality of Life (WHOQOL) and the diabetes-specific Diabetes Quality of Life (DQOL) and Audit of Diabetes-Dependent Quality of Life (ADDQoL)]. Seven instruments more accurately measure health status [Short-Form 36 (SF-36), EuroQoL 5-Dimension (EQ-5D)], treatment satisfaction [Diabetes Treatment Satisfaction Questionnaire (DTSQ)] and psychological well-being [Beck Depression Inventory (BDI), Hospital Anxiety and Depression Scale (HADS), Well-Being Questionnaire (W-BQ), Problem Areas in Diabetes (PAID)]. Conclusions No single measure can suit every purpose or application but, when measures are selected inappropriately and data misinterpreted, any conclusions drawn are fundamentally flawed. If we value QoL as a therapeutic goal, we must ensure that the instruments we use are both valid and reliable. QoL assessment has the proven potential to identify ways in which treatments can be tailored to reduce the burden of diabetes. With careful consideration, appropriate measures can be selected and truly robust assessments undertaken successfully. [source]
