Modular product architectures have generated numerous benefits for companies in terms of cost, lead-time and quality. The defined interfaces and the module’s properties decrease the effort to develop new product variants, and provide an opportunity to perform parallel tasks in design, manufacturing and assembly. The background of this thesis is that companies perform verifications (tests, inspections and controls) of products late, when most of the parts have been assembled. This extends the lead-time to delivery and ruins benefits from a modular product architecture; specifically when the verifications are extensive and the frequency of detected defects is high. Due to the number of product variants obtained from the modular product architecture, verifications must handle a wide range of equipment, instructions and goal values to ensure that high quality products can be delivered. As a result, the total benefits from a modular product architecture are difficult to achieve. This thesis describes a method for planning and performing verifications within a modular product architecture. The method supports companies by utilizing the defined modules for verifications already at module level, so called MPV (Module Property Verification). With MPV, defects are detected at an earlier point, compared to verification of a complete product, and the number of verifications is decreased. The MPV method is built up of three phases. In Phase A, candidate modules are evaluated on the basis of costs and lead-time of the verifications and the repair of defects. An MPV-index is obtained which quantifies the module and indicates if the module should be verified at product level or by MPV. In Phase B, the interface interaction between the modules is evaluated, as well as the distribution of properties among the modules. The purpose is to evaluate the extent to which supplementary verifications at product level is needed. Phase C supports a selection of the final verification strategy. The cost and lead-time for the supplementary verifications are considered together with the results from Phase A and B. The MPV method is based on a set of qualitative and quantitative measures and tools which provide an overview and support the achievement of cost and time efficient company specific verifications. A practical application in industry shows how the MPV method can be used, and the subsequent benefits

BACKGROUND: International organisations, e.g. WHO, stress the importance of competent registered nurses (RN) for the safety and quality of healthcare systems. Low competence among RNs has been shown to increase the morbidity and mortality of inpatients. OBJECTIVES: To investigate self-reported competence among nursing students on the point of graduation (NSPGs), using the Nurse Professional Competence (NPC) Scale, and to relate the findings to background factors. METHODS AND PARTICIPANTS: The NPC Scale consists of 88 items within eight competence areas (CAs) and two overarching themes. Questions about socio-economic background and perceived overall quality of the degree programme were added. In total, 1086 NSPGs (mean age, 28.1 [20-56]years, 87.3% women) from 11 universities/university colleges participated. RESULTS: NSPGs reported significantly higher scores for Theme I "Patient-Related Nursing" than for Theme II "Organisation and Development of Nursing Care". Younger NSPGs (20-27years) reported significantly higher scores for the CAs "Medical and Technical Care" and "Documentation and Information Technology". Female NSPGs scored significantly higher for "Value-Based Nursing". Those who had taken the nursing care programme at upper secondary school before the Bachelor of Science in Nursing (BSN) programme scored significantly higher on "Nursing Care", "Medical and Technical Care", "Teaching/Learning and Support", "Legislation in Nursing and Safety Planning" and on Theme I. Working extra paid hours in healthcare alongside the BSN programme contributed to significantly higher self-reported scores for four CAs and both themes. Clinical courses within the BSN programme contributed to perceived competence to a significantly higher degree than theoretical courses (93.2% vs 87.5% of NSPGs). SUMMARY AND CONCLUSION: Mean scores reported by NSPGs were highest for the four CAs connected with patient-related nursing and lowest for CAs relating to organisation and development of nursing care. We conclude that the NPC Scale can be used to identify and measure aspects of self-reported competence among NSPGs.

Este estudo tem por finalidade identificar perspectiva dos profissionais de Recursos Humanos a correlação entre as competências gerenciais e a relação construída entre líderes de diferentes níveis hierárquicos e suas equipes diretas, bem como o impacto na percepção da pressão e do estresse pelas suas respectivas equipes. Um dos desafios que gerentes e outros líderes encontram é como manter um time motivado e mobilizado em um ambiente de pressão crescente, seja decorrente de uma expansão ou uma retração do seu mercado. No primeiro capítulo e no segundo capítulos fazemos a introdução e a definição do Problema, os objetivos e delimitações do estudo. No terceiro capítulo caminhamos pela história do trabalho, da organização e do homem, buscando fundamentar no tempo a jornada em busca do equilíbrio trabalho e trabalhador, o lugar do homem na construção desta história e alguns importantes pensadores da gestão de pessoas. Este capítulo abre portas para entendermos o capítulo seguinte, no qual estudamos o estresse e, em particular, o estresse ocupacional. Mostramos, ainda, a diferença entre pressão – que está no ambiente externo- e estresse, que deriva da percepção do indivíduo. O interesse neste tema é decorrente da constatação prática de que a pressão aumenta em tempos de retração do mercado, mas também aumenta em períodos em o mercado está aquecido. Logo, se houver uma correlação entre como uma equipe ou um liderado ‘percebe’ o seu líder, essa informação poderá ser útil para a Gestão de Pessoas. Aprofundamos o conceito de Suporte Social, a rede que protege o colaborador nem contextos de alta pressão e demos maior ênfase ao papel do líder como importante fonte deste suporte. No quinto capítulo analisamos o tema conflito por ser um dos temas que mais impactam o estresse ocupacional. As relações de trabalho são, por sua natureza, relações de longo prazo, o que faz do manejo adequado do conflito no ambiente de trabalho um assunto relevante na agenda do gerente. Entretanto, seu manejo adequado depende tanto do diagnóstico correto, bem como da relação de confiança construída pelo líder. Embora cientes de que parte significativa dos conflitos está relacionada às estruturas e estratégias corporativas, propositalmente dirigimos nossa atenção aos gerentes e líderes que compõem a massa de liderança dessas organizações visando provocar idéias que possam contribuir para a melhoria das relações e dos resultados. No sexto capitulo apresentamos a Metodologia e no último capítulo apresentamos e discutimos o resultado da pesquisa realizada com profissionais de Recursos Humanos de grandes empresas, buscando, através do olhar do RH, uma percepção sobre as lideranças de cada empresa e a comparação entre líderes com maior ou menor capacidade de negociação junto à sua equipe. O estudo usou uma grade flexível suportada por um questionário semi-estruturado e os dados foram tratados usando a metodologia da Análise de Conteúdo sem que fosse necessário um tratamento estatístico devido ao tamanho da amostra. O estudo apontou para a necessidade de uma exploração mais profunda do tema uma vez que a literatura e os resultados iniciais demonstraram um importante papel da chefia direta na percepção grupal do estresse e no clima organizacional. Ao concluir o trabalho a pesquisa oferece algumas ponderações sobre o papel das lideranças e o papel das corporações na equalização de equipes que vivem sob pressão constante.

Este trabalho se propõe a analisar o fenômeno das organizações em Rede, dando ênfase às Redes Sociais baseando-se no conceito de que são formadas por laços de solidariedade, com valores coletivos. Redes são sistemas organizacionais que concentram indivíduos e instituições, de forma democrática e participativa, em tomo de objetivos afins. As redes se caracterizam pelas relações horizontais, de ações dinâmicas e que visam ao trabalho integrado. Os tipos de redes variam no que tange a autonomia dos atores e a interdependência que os mesmos estabelecem entre si, mas em comum este estilo de gestão busca uma maior participação e compromisso dos atores envolvidos. O trabalho está dividido em quatro capítulos: O primeiro pretende introduzir o leitor ao tema em que a pesquisa está inserida: redes sociais e intercâmbio cultural. O segundo capitulo apresenta o cenário em que o tema está inserido. O terceiro capítulo apresenta a pesquisa empírica, na qual é utilizado o método de estudo de caso, com a finalidade de investigar o processo de implementação de uma organização em rede - Rede Latitudes - cujo objetivo é o de promover o intercâmbio e a cooperação cultural nestes países. E finalmente, no quarto e último capítulo pretende-se averiguar até que ponto a teoria se aplica na prática. Como se dá o processo de implementação de uma rede com característica social.

O objetivo geral deste estudo consistiu em identificar as dimensões da burocracia e relacioná-las aos elementos de disfunção burocrática existentes em uma unidade da administração pública estadual, no âmbito da Criminalística, que influenciam a Qualidade de Vida no Trabalho (QVT), considerando as abordagens humanista e restritiva, no contexto da Coordenadoria Geral de Perícias (CGP), a partir da percepção dos servidores lotados nesta unidade da Segurança Pública. Utilizou-se a pesquisa descritiva por meio de uma abordagem qualitativa de estudo de caso, com amostra constituída por peritos criminais do Instituto de Criminalística "Hercílio Macellaro" (ICHM), lotados na Capital do Estado, Campo Grande - MS. O método de coleta de dados adotado para a constatação das disfunções burocráticas foi um questionário com assertivas fechadas de alternativas de múltipla escolha, cujo modelo de resposta compõe-se por quatro níveis de gradação (sempre, muitas vezes, poucas vezes, nunca), elaborado a partir do modelo de Maia e Pinto (2007). Em outro momento, foi aplicado o questionário apresentando questões que abordavam os elementos da QVT propostos por Werther e Davis (1983), adaptado para o presente estudo. Para este questionário, as questões foram apresentadas em escala polarizada de satisfação do tipo Likert, composta por cinco alternativas (discordo totalmente, discordo parcialmente, não concordo nem discordo, concordo parcialmente e concordo totalmente), caracterizando a opinião do participante. A interpretação dos dados permitiu analisar a existência de quatro elementos de disfunção burocrática: internalização das regras, excesso de formalismo, rotinas e registros, resistência às mudanças e exibição de sinais de autoridade. De uma lado, a abordagem humanista foi possível analisar que os respondentes da pesquisa evidenciam ruídos na comunicação, tanto vertical quanto horizontal, o que indica a necessidade de mais transparência e clareza possível dentro e entre as equipes nos departamentos e destes com os superiores hierárquicos, a fim de proporcionar maior entendimento entre todos os envolvidos e a eliminação de conflitos que possam ocorrer através de informações distorcidas. Por outro lado, a análise da abordagem restritiva sobre a QVT neste estudo permitiu observar a predominância da racionalidade instrumental no contexto organizacional do ICHM, uma vez que está voltada somente para atender a seus processos organizacionais fundamentados no binômio técnica versus produção. Pode-se, assim, considerar que o ICHM está fortemente ligado ao modelo de organização burocrática, exteriorizado por quatro níveis de disfunções burocráticas. Além disso, como pretexto pela busca da eficiência, eficácia e efetividade, a práxis organizacional do ICHM parece convergir para dois modelos de produção: fordista e taylorista, as quais reforçam a corrente restritiva da QVT, que parece confirmar a manutenção da coisificação do sujeito em relação ao objeto, isto é, quando se pensava que o ser orgânico pudesse desfrutar do desenvolvimento tecnológico alcançado em várias ciências, paradoxalmente, o que tem sido visto é o trabalho como um fim em si mesmo.

Boal, Malvasia, Sercial and Verdelho are the main white grape varieties used in Madeira wine production. To estimate the free fraction of varietal aroma compounds of these varieties, 39 samples of musts were analysed to determine their content of monoterpenols and C13 norisoprenoids (terpenoids), using dynamic headspace solid-phase microextraction coupled with gas chromatography–mass spectrometry. The r-values for linearity studies of the analytical method used, varied between 0.977 (nerolidol) and 0.999 (linalool). The repeatability for each compound varied between 2.5% (citronellol) and 11.8% (β-ionone). The mean values from three vintages (1998, 1999 and 2000) confirmed that these musts have differentiated contents of terpenoids. In opposition to Verdelho musts, Malvasia showed the highest free terpenoids content. In order to establish relations between the compounds and the varieties under investigation, principal component analysis and linear discriminant analysis were applied to the data, revealing a good separation and classification power between the four groups as a function of varietal origin.

The current paper aims at analyzing customer retention in Internet provider services. For this study, we sought to understand what are the client's expectations regarding the services available and compare them with management perception in relation to the use of those services. Identifying the coherence level between the two points of view, management and client, it is possible to pinpoint how service is assessed in real conditions. Then, from this point on, a new vision can be implemented on available services, and new customer service strategies aiming at best serving to their expectation and need, can be rethought. The exploratory research was utilized. It was based on case study, and quantitative and qualitative methods were used. The quantitative method was done by applying the cluster technique with six variables of control derived from the six main services, whose definition was done through qualitative survey of the internal management team. Then, an structured interview with 443 clients, from a probabilistic sample of 800 costumers. The total number of active clients of the internet provider is of 10.677. Client perception in relation to services varied, if compared with the four services that were under the managerial metric method, this comparison showed a more positive evaluation than the real use of the service. Thus, it was observed that the value of each service available for the client depends on his/her perception of it, regardless of using or not the offered service. As a result, it is possible to understand which services offered by the company under study effectively contribute to a good client-company relationship, and the upkeep of those clients

The present dissertation analyzes the performance and acting of the Rio Grande do Norte Public Ministery, in the strategic perspective, while responsible Institution for the defense of the collective rights. The comprehension of this theme inserts in a context of modernization of the public administration, in which is inserted, as well as their functional and structural changes, in a reality of innovations there is passing the organizations, looking to rescue the legitimacy of the government organizations, aligning them to the democratic values of the society. It detaches the strategic administration and the public administration and it exposes the strategic performance about the central point of the study, focusing in the development of the organization in the last four years, and other relative subjects to the acting. It is a unic case study, framed in the characteristics of the qualitative approaches - descriptive and exploratory. The analysis showed, through the method of content analysis, by the criterion of thematic categorization, that MP / RN come developing in an intense way,and it detaches that the changes already happened reflect a good strategic acting of the Institution, especially in the structural and functional areas, showing the strategic conscience of this, although that is not still enough to consider it as a strategic organization, and it concludes that there is still a lot for doing, and that the occurrence of an administration typically strategic in the extent of MP/RN is possible, with the conscience and participation of all, members and servants

You cannot teach architectonic design, but only learn it. This sentence was, during some decades, especially during the modernism, the starting point, adopted by several architectonic design professors, when they had to approach their subject. An attitude that, some years ago, was reviewed and fighted by area s experts. This paper join this criticism, and try to add something to the pre-existing discussion, analyzing with the case-study method all the subjects related with architectonic design of the Architecture and Urbanism degree, at Universidade Federal do Rio Grande do Norte CAU/UFRN . The aim is to identify and analyze the teaching methodologies used by the professors and their effects related to the students. To reach this purpose four different methods were used: i) Professors interviews; ii) Different forms submitted to students and professors; iii) Daily practice s observation, developed during classes; iv) Documents analysis about the degree (historical development and subjects) and about the subjects themselves (summaries, table of contents and planning). Studying the results, it was possible to underline that, in spite of the efforts of some of the professors to find a way to teach with more appropriate educational and pedagogic bases, some of the teaching methodologies, criticized in articles dealing with the matter, were still used. With regard to these, the research pointed out some suggestions that could help to improve the teaching and learning process, joining professors and students that are the most important subjects of the teaching activity. Developing the idea living in the paper s title Teaching and learning , it s now clear that only the practice, through the improvement of the pedagogic techniques, together with critical analysis can help the professors to reach a relationship level, regarding the teaching and learning process, as that described in the epigraph s text, into which teaching and learning, can t be done only by one of the process subject, but must be lived by both of them: professors and students

The starting point of the present work consisted of investigating the development of biotechnology in the Northeast region of Brazil from the perspective of a Regional Innovation System (RIS). The theoretical framework adopted relied on the approaches and concepts presented by the Neo-Schumpeterian perspective. This framework was chosen because, by means of the Innovation System concept, this literature allows us to analyze the relationships and configurations of actors, as well as the role of the state and of social, science and technology, and economic policies in the studied region. The analysis considered four selected dimensions: physical infrastructure, human capital, scientific production, and funding. These variables were chosen because they allow us to verify the possibilities and limitations of developing a biotechnology RIS in the Northeast of Brazil, and these elements would help in answering the question behind this dissertation. The location of the physical infrastructure was determined by means of bibliographic and documental research and interviews with heads of institutions that do biotechnology research. Regarding human capital, the analysis focused on resource training in biotechnology, highlighting graduate courses and research groups in the area. To measure knowledge production, we delimited scientific collaboration among researchers in the field of biotechnology as the focus of this category. For the funding dimension, information was gathered from reports available at the websites of national and state funding agencies. The data was analyzed through method triangulation, involving quantitative and qualitative research stages. To back the analyses, we revisited the integration policies in the area of Science, Technology and Innovation. Our analysis has shown that these policies play a crucial role in the development of biotechnology in the region being studied. The data revealed that the physical infrastructure is concentrated in only three states (Bahia, Ceará, and Pernambuco). In this regard, the Northeast Biotechnology Network (Renorbio) stands out as a strategic actor, enabling states with poor infrastructure to develop research through partnerships with institutions located in another state. We have also verified that the practices involving human resource training and knowledge production are factors that enable the emergence of a regional system for biotechnology in the studied region. As limitations, we have verified the low immersion level of regional actors, the heterogeneity of socioeconomic indicators, the lack of financial resources, and a low innovation culture in the business sector. Overall, we have concluded that the development of a Regional Innovation System in Biotechnology, based on the current regional dynamics, depends on an effective change in the behavior of the social agents involved, both in the national and regional dimensions as well as in the public and private spheres

The increasing use of fossil fuels in line with cities demographic explosion carries out to huge environmental impact in society. For mitigate these social impacts, regulatory requirements have positively influenced the environmental consciousness of society, as well as, the strategic behavior of businesses. Along with this environmental awareness, the regulatory organs have conquered and formulated new laws to control potentially polluting activities, mostly in the gas stations sector. Seeking for increasing market competitiveness, this sector needs to quickly respond to internal and external pressures, adapting to the new standards required in a strategic way to get the Green Badge . Gas stations have incorporated new strategies to attract and retain new customers whom present increasingly social demand. In the social dimension, these projects help the local economy by generating jobs and income distribution. In this survey, the present research aims to align the social, economic and environmental dimensions to set the sustainable performance indicators at Gas Stations sector in the city of Natal/RN. The Sustainable Balanced Scorecard (SBSC) framework was create with a set of indicators for mapping the production process of gas stations. This mapping aimed at identifying operational inefficiencies through multidimensional indicators. To carry out this research, was developed a system for evaluating the sustainability performance with application of Data Envelopment Analysis (DEA) through a quantitative method approach to detect system s efficiency level. In order to understand the systemic complexity, sub organizational processes were analyzed by the technique Network Data Envelopment Analysis (NDEA) figuring their micro activities to identify and diagnose the real causes of overall inefficiency. The sample size comprised 33 Gas stations and the conceptual model included 15 indicators distributed in the three dimensions of sustainability: social, environmental and economic. These three dimensions were measured by means of classical models DEA-CCR input oriented. To unify performance score of individual dimensions, was designed a unique grouping index based upon two means: arithmetic and weighted. After this, another analysis was performed to measure the four perspectives of SBSC: learning and growth, internal processes, customers, and financial, unifying, by averaging the performance scores. NDEA results showed that no company was assessed with excellence in sustainability performance. Some NDEA higher efficiency Gas Stations proved to be inefficient under certain perspectives of SBSC. In the sequence, a comparative sustainable performance and assessment analyzes among the gas station was done, enabling entrepreneurs evaluate their performance in the market competitors. Diagnoses were also obtained to support the decision making of entrepreneurs in improving the management of organizational resources and promote guidelines the regulators. Finally, the average index of sustainable performance was 69.42%, representing the efforts of the environmental suitability of the Gas station. This results point out a significant awareness of this segment, but it still needs further action to enhance sustainability in the long term

We did a numerical investigation of the propagation of short light pulses in the region of 1.55 mu m and the conversion efficiency (CE) for the four wave mixing generation (FWM) of ordinary and dispersion decreasing fibers for use in wavelength division multiplexing (WDM) systems, Our simulations studies three different profiles, linear, hyperbolic. and constant, One conclude that for all the profiles there is decrease of the conversion efficiency with the increase in the channel separation. The hyperbolic profile present a higher efficiency of around 1000 above in magnitude compared with the others profiles at 0.2 nm of channel separation. We calculate the conversion efficiency versus the fiber length for the three profiles. The conversion efficiency for the hyperbolic profile is higher when compared to the constant and linear profiles. The other interesting point of the hyperbolic profile is that the increase of the CE in the beginning of the fiber does not show my oscillation in the CE value (log eta), which was observed for the constant and linear profiles. For all the profiles there is an increase of the conversion efficiency with the increase of the pump power. The compression factor C-i for the generated FWM signal at omega(3) was measured along the DDF's and the constant profile fibers. One can conclude that with the use of decreasing dispersion profile (DDF) fibers one can have a control of the (CE) conversion efficiency and the compression factor of the four wave mixing (FWM) generation in WDM systems.

Hypertensive syndromes in pregnancy (HSP) are configured as one of the major complications in the pregnancy and postpartum period and can lead premature newborn and subsequent hospitalization of the newborn to the Neonatal Intensive Care Unit (NICU). This study aimed to analyze the perceptions, meanings and feelings of mothers on the hypertensive syndromes in pregnancy and premature obstetric labor. The research was qualitative and has a theoretical methodological the Social Representations Theory(SRT) in the approach to the Central Nucleus Theory. The study included 70 women, mean age 29 years, predominantly school to high school, most of them married or in consensual union, primiparous and prevalence of cesarean delivery occurred between 32 and 37 weeks of pregnancy.The data were collected from may to december 2008 in the Maternity School Januário Cicco in Natal , and obtained through the following instruments for data collection: questionnaire including questions about socio-demographic status; the Free Words Association Test (FWAT) and and verbalized mental image construction used three stimuli: such as pregnancy with high blood pressure, preterm birth and NICU, and interview with the following guiding question: what it meant for you to have a pregnancy with high blood pressure and consequently the birth of a premature baby? Data analysis was performed using multi-method obtained from the data processing by EVOC (Ensemble Programmes Permettant L 'Analyze des Évocations) and ALCESTE (Analyse Lexicale par Contexte d'un Ensemble de Segment de Texte) and thematic analysis in categories. The results will be presented in four thematic units under the following representative universes: HSP, prematurity as a result of HSP, NICU and the social representations of mothers on the hypertensive disorder of pregnancy sequenced premature birth and hospitalization of the child in the NICU. The results obtained by multimethod analyses showed similar constructions and point to death as the central nucleus and negative aspects, coping strategies, need of care, knowledge about the disease, fragility and meanings of the NICU as peripheral elements. It is considered that the perceptions, meanings and feelings of puerperal women in relation to HSPs and to premature delivery are a negative social representation, with representational elements that may have influenced the adverse effects on the disease and its consequences. We suggest action on the peripheral elements of this representation, with adequate orientation, early diagnosis, effective conduct, receptive attitude on the part of the team, health promotion measures and effective public policies, in order to improve the care provided to puerperal women, making them feel welcome and minimizing their suffering
