Schizophrenic public administration reform in Hungary. Tension between anti-NPM systemic and pro-NPM organizational reforms

The aim of the paper is to highlight the main characteristics of the recent Hungarian public administration reform, as well as to reveal the inconsistent nature of some of its elements and to describe the connected risks. The starting point of the article is the Magyary Zoltán public administration development programme. The reform steps are compared to the ideal type NPM approach. The Hungarian public administration reform can be characterized by strong centralization and the revitalization of Hungarian anti-liberal traditions at macro level, and by the support of the enhancement of market rules and management at micro level.

Kritikai menedzsmentelméletek – irányzatok és törésvonalak (Critical Management Studies: Streams and Debates)

A tanulmány a kritikai menedzsmentelméletek (KME) területére nyújt bevezetést a Hidegh – Gelei – Primecz (2014) által a Vezetéstudomány hasábjain kezdeményezett cikksorozat részeként. A KME fogalmát a korábbi, szervezetelméleti paradigmákat ismertető tanulmányoktól eltérő módon, a mátrixokon át-/ túllépve lépcsőszerűen tárgyalja. Bemutatja, hogyan definiálhatjuk kritikai módon a menedzsmentet és a menedzsmentelméleteket, majd a KME meghatározása és három legfontosabb jellemzője (denaturalizáció, teljesítményelv-ellenesség, reflexivitás) következik. A cikk ismerteti a KME három legmarkánsabb irányzatát: a posztmodernizmust, a kritikai elméletet és a kritikai realizmust, valamint az irányzatok közötti főbb vitapontokba nyújt betekintést. ____ The article provides an introduction into Critical Management Studies (CMS) continuing the series of papers about CMS started by Hidegh – Gelei – Primecz (2014) on the pages of Budapest Management Review. CMS is defined here in a different way as in the previously published Hungarian articles which were based on the Burrell-Morgan matrix (1979). This study exceeds the boundaries of the matrix by introducing management and management studies as a critical field step by step. The definition of CMS is followed by the main features of the field: denaturalization, anti-performativity and reflexivity (Fournier – Grey, 2000). Finally, the paper discusses the three most prevailing streams of CMS: postmodernism, critical theory and critical realism by providing an insight into the main debates among them.

Active Surface Deformation Technology for Management of Marine Biofouling

Biofouling, the accumulation of biomolecules, cells, organisms and their deposits on submerged and implanted surfaces, is a ubiquitous problem across various human endeavors including maritime operations, medicine, food industries and biotechnology. Since several decades, there have been substantial research efforts towards developing various types of antifouling and fouling release approaches to control bioaccumulation on man-made surfaces. In this work we hypothesized, investigated and developed dynamic change of the surface area and topology of elastomers as a general approach for biofouling management. Further, we combined dynamic surface deformation of elastomers with other existing antifouling and fouling-release approaches to develop multifunctional, pro-active biofouling control strategies.

This research work was focused on developing fundamental, new and environment-friendly approaches for biofouling management with emphasis on marine model systems and applications, but which also provided fundamental insights into the control of infectious biofilms on biomedical devices. We used different methods (mechanical stretching, electrical-actuation and pneumatic-actuation) to generate dynamic deformation of elastomer surfaces. Our initial studies showed that dynamic surface deformation methods are effective in detaching laboratory grown bacterial biofilms and barnacles. Further systematic studies revealed that a threshold critical surface strain is required to debond a biofilm from the surface, and this critical strain is dependent on the biofilm mechanical properties including adhesion energy, thickness and modulus. To test the dynamic surface deformation approach in natural environment, we conducted field studies (at Beaufort, NC) in natural seawater using pneumatic-actuation of silicone elastomer. The field studies also confirmed that a critical substrate strain is needed to detach natural biofilm accumulated in seawater. Additionally, the results from the field studies suggested that substrate modulus also affect the critical strain needed to debond biofilms. To sum up, both the laboratory and the field studies proved that dynamic surface deformation approach can effectively detach various biofilms and barnacles, and therefore offers a non-toxic and environmental friendly approach for biofouling management.

Deformable elastomer systems used in our studies are easy to fabricate and can be used as complementary approach for existing commercial strategies for biofouling control. To this end, we aimed towards developed proactive multifunctional surfaces and proposed two different approaches: (i) modification of elastomers with antifouling polymers to produce multifunctional, and (ii) incorporation of silicone-oil additives into the elastomer to enhance fouling-release performance.

In approach (i), we modified poly(vinylmethylsiloxane) elastomer surfaces with zwitterionic polymers using thiol-ene click chemistry and controlled free radical polymerization. These surfaces exhibited both fouling resistance and triggered fouling-release functionalities. The zwitterionic polymers exhibited fouling resistance over short-term (∼hours) exposure to bacteria and barnacle cyprids. The biofilms that eventually accumulated over prolonged-exposure (∼days) were easily detached by applying mechanical strain to the elastomer substrate. In approach (ii), we incorporated silicone-oil additives in deformable elastomer and studied synergistic effect of silicone-oils and surface strain on barnacle detachment. We hypothesized that incorporation of silicone-oil additive reduces the amount of surface strain needed to detach barnacles. Our experimental results supported the above hypothesis and suggested that surface-action of silicone-oils plays a major role in decreasing the strain needed to detach barnacles. Further, we also examined the effect of change in substrate modulus and showed that stiffer substrates require lower amount of strain to detach barnacles.

In summary, this study shows that (1) dynamic surface deformation can be used as an effective, environmental friendly approach for biofouling control (2) stretchable elastomer surfaces modified with anti-fouling polymers provides a pro-active, dual-mode approach for biofouling control, and (3) incorporation of silicone-oils additives into stretchable elastomers improves the fouling-release performance of dynamic surface deformation technology. Dynamic surface deformation by itself and as a supplementary approach can be utilized biofouling management in biomedical, industrial and marine applications.

Études in vivo et in vitro sur le potentiel néphroprotecteur de plantes médicinales anti-diabétiques de la pharmacopée traditionnelle des Cris de la Baie-James

Notre équipe a identifié le thé Labrador [Rhododendron groenlandicum L. (Ericaceae)] comme une plante potentiellement antidiabétique de la pharmacopée traditionnelle des Cris de la Baie James orientale. Dans la présente étude, nous avons évalué les effets néphroprotecteurs potentiels de la plante. De la microalbuminurie et de la fibrose rénale ont été développées chez des souris alimentées avec une diète grasse (DG). Le R. groenlandicum améliore d’une façon non-significative la microalbuminurie, avec des valeurs de l’aire sous la courbe (ACR) diminuant de 0.69 à 0.53. La valeur de la fibrose rénale qui était, à l’origine, de 4.85 unités arbitraires (UA) dans des souris alimentées à la DG, a chuté à 3.27 UA après avoir reçu un traitement de R. groenlandicum. Le R. groenlandicum a réduit la stéatose rénale de presque la moitié alors que l’expression du facteur de modification Bcl-2 (Bmf) a chuté de 13.96 UA à 9.43 UA. Dans leur ensemble les résultats suggèrent que le traitement avec R. groenlandicum peut améliorer la fonction rénale altérée par DG. Dans l’étude subséquente, notre équipe a identifié 17 espèces de la forêt boréale, de la pharmacopée traditionnelle des Cris de la Baie James orientale, qui ont présenté des activités biologiques prometteuses in vitro et in vivo dans le contexte du DT2. Nous avons maintenant examiné ces 17 extraits afin d’identifier lesquels possèdent un potentiel cytoprotecteur rénale en utilisant des cellules Madin Darby Canine Kidney (MDCK) mises à l’épreuve dans un médium hypertonique. Nous concluons que plusieurs plantes antidiabétiques Cris exercent une activité de protection rénale qui pourrait être pertinente dans le contexte de la néphropathie diabétique (ND) qui affecte une proportion importante des Cris. La G. hispidula et la A. balsamea sont parmi les plantes les plus puissantes dans ce contexte et elles semblent protectrices principalement en inhibant la caspase 9 dans la voie de signalisation apoptotique mitochondriale. Finalement, nous avons utilisé une approche de fractionnement guidée par un test biologique pour identifier les fractions actives et les composés de A. balsamea avec un potentiel de protection rénale in vitro dans des cellules MDCK mises au défi avec un médium hypertonique. La fraction d’hexane (Hex) possède le potentiel le plus élevé parmi toutes les fractions de solvant contre les dommages cellulaires induits par le stress hypertonique. Dans des études précédentes, trois composés purs ont été identifiés à partir de la fraction Hex, à savoir, l’acide abiétique, l’acide déhydroabiétique et le squalène. L’acide abiétique se distinguait par son effet puissant dans le maintien de la viabilité des cellules MDCK (AnnV-/PI-) à un niveau relativement élevé (augmentation de 25.48% relative au stress hypertonique, P<0.0001), ainsi qu’une réduction significative (diminution de 20.20% par rapport au stress hypertonique, P<0.0001) de l’apoptose de stade précoce (AnnV+/PI-). L’acide abiétique peut donc servir à normaliser les préparations traditionnelles d’A. balsamea et à trouver des applications potentielles dans le traitement de la néphropathie diabétique. Les trois études ont été intrinsèquement liées les unes aux autres, par conséquent, nous avons réussi à identifier R. groenlandicum ainsi que A. balsamea comme nouvelles plantes prometteuses contre la néphropathie diabétique. Nous croyons que ces résultats profiteront à la communauté crie pour la gestion des complications diabétiques, en particulier la néphropathie diabétique. En parallèle, nos données pourraient faire avancer l'essai clinique de certaines plantes médicinales de la pharmacopée traditionnelle des Cris de la Baie James orientale du Canada.

Construção das capacidades organizacionais de tecnologia da informação no contexto dos sistemas institucionais integrados de gestão da UFRN

The IT capability is a organizational ability to perform activities of this role more effectively and an important mechanism in creating value. Its building process (stages of creation and development) occurs through management initiatives for improvement in the performance of their activities, using human resources and IT assets complementary responsible for the evolution of their organizational routines. This research deals with the IT capabilities related to SIG (integrated institutional management systems), built and deployed in UFRN (Universidade Federal do Rio Grande do Norte) to realization and control of administrative, academic and human resources activities. Since 2009, through cooperative agreements with federal and educational institutions of direct administration, UFRN has supported the implementation of these systems, currently involving more than 30 institutions. The present study aims to understand how IT capabilities, relevant in the design, implementation and dissemination of SIG, were built over time. This is a single case study of qualitative and longitudinal nature, performed by capturing, coding and analysis from secondary data and from semi-structured interviews conducted primarily with members of Superintenência de Informática, organizational unit responsible for SIG systems in UFRN. As a result, the technical, of internal relationship and external cooperation capabilities were identified as relevant in the successful trajectory of SIG systems, which have evolved in different ways. The technical capacity, initiated in 2004, toured the stages of creation and development until it reached the stage of stability in 2013, due to technological limits. Regarding the internal relationship capability, begun in 2006, it toured the stages of creation and development, having extended its scope of activities in 2009, being in development since then. Unlike the standard life cycle observed in the literature, the external cooperation capability was initiated by an intensity of initiatives and developments in the routines in 2009, which were decreasing to cease in 2013 in order to stabilize the technological infrastructure already created for cooperative institutions. It was still identified the start of cooperation in 2009 as an important event selection, responsible for changing or creating trajectories of evolution in all three capacities. The most frequent improvements initiatives were of organizational nature and the internal planning activity has been transformed over the routines of the three capabilities. Important resources and complementary assets have been identified as important for the realization of initiatives, such as human resources technical knowledge to the technical capabilities and external cooperation, and business knowledge, for all of them, as well as IT assets: the iproject application for control of development processes, and the document repository wiki. All these resources and complementary assets grew along the capacities, demonstrating its strategic value to SINFO/UFRN

Desempenho internacional de empresas exportadoras: um modelo estrutural baseado em capacidades organizacionais e ambiente

The internationalization as an organizational phenomenon fundamentally strategic had as theoretical contributions some Schools that throughout the decades 60, 70, and 80 developed behavioral and economic approaches in order to explain the process. The behavioral approach deals with the perception of phenomenon as a gradual process from the perspective of the executives behavior (JOHANSON and VAHLNE, 1977; HALLÉN and WIEDERSHEIM - PAUL, 1979; CZINKOTA, 1985). This phenomenon in permanent theoretical and managerial evolution made an opportunity to build this investigation, whose goal is to analyse the impact comes from organizational capabilities and the external environment on the international performance of exporting firms. For both, were used as theoretical basis two types of analysis for the comprehension of international performance: Strategic Management - Industrial Organization and Resource-Based View and International Businesses - Current Economic and Behavioral. It was made a cross-sectional survey-based explanatory research, including 150 exporting companies with operations in the Northeast of Brazil. A conceptual model was made with eight constructs and eight research hypotheses, representative of the effects of external factors on international performance. The data were processed using the Exploratory Factor Analysis and Structural Equation Modeling. The structural equations model was reespecified and estimated through the use of the maximum-likelihood method up to achieve adequated values of indexes of adjustment. As the main theoretical contribution, were identified organizational and physical resources which shows the importance of the management skills development, of the learning capability and capability to establish strategic alliances abroad. That because the knowledge, as the operational point of view as in its strategic application, offers to organization conditions of market positioning which can create opportunities sustainable competitive advantages and which impact the performance of international companies

Analise das melhores práticas em business process management: estudo de casos em organizações hospitalares de Natal/RN

O gerenciamento dos processos organizacionais vem sendo estudado pela ciência administrativa como forma de romper com o paradigma da estrutura organizacional funcional através da Gestão por Processos. O Business Process Management ( BPM alinhado às estratégias organizacionais e suportado cada vez mais pela Tecnologia da Informação (TI), proporciona clareza nas diversas pontas do processo colaborando para sua melhoria contínua com o objetivo de gerar valor agregado ao cliente. As organizações de saúde estão entre as empresas prestadoras de serviço pouco estudadas em relação ao gerenciamento por processos. Assim, este estudo analisou por meio de um estudo empírico de natureza qualitativa, como estão sendo conduzidos os processos organizacionais hospitalares à luz das melhores práticas em BPM. A pesquisa foi realizada através do estudo de casos múltiplos realizados em duas organizações hospitalares na cidade de Natal/RN. A literatura de referência apresentou diversos fatores para um desempenho otimizado em BPM, tratados nesta pesquisa como as melhores práticas em BPM. A partir da revisão da literatura foi elaborada uma síntese das melhores práticas de BPM que serviu de base para elaboração do modelo da pesquisa utilizado para coleta e análise dos dados. Este modelo indicou onze categorias que foram utilizadas para elaboração do roteiro de estrevistas semi-estruturadas, através da técnica de análise de conteúdo, com categorização de grade fechada. As categorias foram agrupadas em duas dimensões: Elementos relacionados à gestão ( governança ; liderança , alinhamento estratégico , cultura e conhecimento ) e elementos relacionados aos processos ( desenho , responsável , executores , tecnologia da informação e indicadores ), e ainda foi identificada uma terceira categoria: escritório de processos . Para seleção dos sujeitos desta pesquisa foi adotada a estratégia em cadeia ou bola de neve . Foi possível identificar que todas as categorias apontadas no modelo de pesquisa emergem entre os fatores buscados pelas organizações hospitalares para o gerenciamento por processos com destaque para categorias: cultura ; conhecimento ; desenho ; tecnologia da informação e indicadores . Em complemento às categorias de análise, foram identificadas dificuldades relacionadas à comunicação e integração dos diversos elos do processo. Além disso, constatou-se que nos hospitais investigados há um desvio do conceito de BPM no que diz respeito a seu objetivo final: agregar valor ao cliente. A pesquisa concluiu que o gerenciamento por processos nas organizações hospitalares investigadas encontra-se em fase inicial ou em desenvolvimento, sendo necessário superar as barreiras da comunicação e edificar uma cultura organizacional orientada às necessidades dos clientes para aplicação das melhores práticas de BPM, desta forma pesquisas futuras sobre este tema em outras organizações hospitalares, podem facilitar um estudo comparativo e ampliar o conhecimento no assunto

PHC Production Management System Based on RFID

At present, in large precast concrete enterprises, the management over precast concrete component has been chaotic. Most enterprises take labor-intensive manual input method, which is time consuming and laborious, and error-prone. Some other slightly better enterprises choose to manage through bar-code or printing serial number manually. However, on one hand, this is also labor-intensive, on the other hand, this method is limited by external environment, making the serial number blur or even lost, and also causes a big problem on production traceability and quality accountability. Therefore, to realize the enterprise’s own rapid development and cater to the needs of the time, to achieve the automated production management has been a big problem for a modern enterprise. In order to solve the problem, inefficiency in production and traceability of the products, this thesis try to introduce RFID technology into the production of PHC tubular pile. By designing a production management system of precast concrete components, the enterprise will achieve the control of the entire production process, and realize the informatization of enterprise production management. RFID technology has been widely used in many fields like entrance control, charge management, logistics and so on. RFID technology will adopt passive RFID tag, which is waterproof, shockproof, anti-interference, so it’s suitable for the actual working environment. The tag will be bound to the precast component steel cage (the structure of the PHC tubular pile before the concrete placement), which means each PHC tubular pile will have a unique ID number. Then according to the production procedure, the precast component will be performed with a series of actions, put the steel cage into the mold, mold clamping, pouring concrete (feed), stretching, centrifugalizing, maintenance, mold removing, welding splice. In every session of the procedure, the information of the precast components can be read through a RFID reader. Using a portable smart device connected to the database, the user can check, inquire and management the production information conveniently. Also, the system can trace the production parameter and the person in charge, realize the traceability of the information. This system can overcome the disadvantages in precast components manufacturers, like inefficiency, error-prone, time consuming, labor intensity, low information relevance and so on. This system can help to improve the production management efficiency, and can produce a good economic and social benefits, so, this system has a certain practical value.

Um sistema multiagente multidimensional para simulação de processos de produção e gestão social de um ecossistema urbano: uma abordagem baseada na integração de artefatos organizacionais, normativos, físicos e de comunicação no JaCaMo

Esta dissertação apresenta a modelagem de uma ferramenta baseada em SMA para a simulação da produção e gestão social de um ecossistema urbano, a organização social do Projeto da Horta San Jeronimo(SJVG), localizado no Parque San Jeronimo Sevilha, Espanha, que e coordenado pela confederação Ecologistas en Accion . Estes processos sociais observados no projeto do SJVG são caracterizados pela ocorrência de uma serie de interações e trocas sociais entre os participantes. Além disso, os comportamentos periódicos, interações e comunicações são regulados pelo Regimento de Normas Internas, estabelecidos pela comunidade em assembleia, sob a supervisão e coordenação da confederação EA. O SMA foi concebido como um sistema JaCaMo multidimensional, composto por cinco dimensões integradas: a população de agentes, os artefatos normativos (a organização), os artefatos físicos (o ambiente dos agentes), artefatos de comunicação (o conjunto de interações) e os artefatos normativos (política normativa interna). A ferramenta utilizada no projeto e o framework JaCaMo, uma vez que apresenta suporte de alto nível e modularidade para o desenvolvimento das três primeiras dimensões acima mencionadas. Mesmo tendo enfrentado alguns problemas importantes que surgiram adotando o framework JaCaMo para desenvolvimento do Projeto SJVG-SMA, como: (i) a impossibilidade de especificação da periodicidade no modelo MOISE, (II) a impossibilidade de definir normas, seus atributos básicos (nome, periodicidade, papel a que se aplica) e as sanções, e (III) a inexistência de uma infraestrutura modular para a definição de interações através da comunicação, foi possível adotar soluções modulares interessantes para manter a ideia de um SMA de 5 dimensões, desenvolvidos na plataforma JaCaMo. As soluções apresentadas neste trabalho são baseadas principalmente no âmbito do Cartago, apontando também para a integração de artefatos organizacionais, normativos, físicos e de comunicação.

As inovações organizacionais do PROCANA

Nos países ocidentais, a pesquisa científica financiada com recursos públicos vem sofrendo reformas dramáticas nas últimas duas décadas (Simpson, 2003). Considerando os resultados dessas reformas, este artigo investiga como as mesmas aconteceram no Brasil, como os programas de pesquisa foram afetados e qual estilo de organização emergiu das reformas. Pretende-se analisar essas questões empiricamente, usando um estudo de caso. Então, o objetivo específico desse artigo é analisar as inovações organizacionais criadas dentro de um programa de pesquisa público brasileiro – o Programa de melhoraento genético da cana-de-açúcar do IAC (PROCANA) – para enfrentar as reformas nos modelos de atuação do Estado na área de C&T, superar os limites geográficos da pesquisa agrícola, dar mais eficiência à P&D e gerar produtos adaptados às necessidades dos usuários.

The importance of organizational commitment to knowledge management

In recent years, Knowledge Management (KM) has assumed great importance in the literature on business and management. However, we still have so little understanding of the human issues in KM processes. Thus, this research aims to contribute to analysing the importance of Organizational Commitment (OC) to KM. First, we used the Cardoso (2003) Knowledge Management Questionnaire (QGC) that embraces all organizational activities around knowledge processes and distinguishes four dimensions of KM. Secondly we applied the Quijano, Masip, Navarro and Aubert (1997) questionnaire (ASH-ICI) that distinguishes two types of commitment (personal and instrumental) into four dimensions. These two questionnaires were applied with 300 employees in the Portuguese industrial ceramics sector. Through multiple regression analysis we found that levels of organizational commitment are statistically important to KM dimensions. Furthermore, our analysis indicates that personal commitment is more important than need commitment. These results are discussed and Organizational Behaviour specialists and Work and Organizational psychologists are challenged to assume more responsibility and an active role in KM studies and practices and to explore human issues in this field.

A criaçao de climas organizacionais geradores de criatividade e de inovação organizacional: Estudos de caso em contextos culturais diferenciados

Devido ao contexto económico vivido actualmente, de muita concorrência e de incerteza, impõe-se a aposta em fazer diferente, em fazer melhor e a um menor custo. Tal caminho pode ser percorrido com recurso à criatividade e inovação resultando deste binómio elementos potenciadores de mais-valias para a empresa e para o consumidor. Será que o ambiente organizacional influencia o aparecimento de criatividade e inovação? A opinião de que o ambiente é realmente muito importante para tal acontecer é partilhada por vários autores. A cultura organizacional, a forma como é considerado o indivíduo dentro da organização, como é feita a gestão de talentos, a forma como são encorajadas as ideias de todos os indivíduos pode realmente ser um factor decisivo para facilitar e encorajar a criatividade e inovação na empresa. A abordagem empírica assenta num estudo qualitativo, para o qual foram seleccionadas três empresas. A selecção de duas das empresas teve em conta o seu posicionamento no mercado como empresas inovadoras e a terceira pelo facto do seu core business estar directamente relacionado com a criatividade. Através do estudo realizado conclui-se que a cultura e o clima organizacional, ou seja, a forma como é visto o colaborador, como lhe é dado poder de decisão, como é reconhecido o seu esforço, trabalho e empenho, influencia os níveis de criatividade e inovação dentro da Organização. ABSTRACT; Due to the current economic context, marked by a fierce competition and uncertainty, it is necessary to focus on making differently, better and cheaper. Such path can be followed using creativity and innovation. Profit-boosting elements for the company and the consumer. Does the work environment affect the occurrence of creativity and innovation? Several authors share the opinion that the environment is very important for that occurrence. The organizational culture, the way how the individual is perceived inside the organization, how the management of talents is made, the ideas from all individuals are seen, can be a major to facilitate and encourage creativity and innovation in the company.
