Resident's perceptions on impacts of hosting the “Guimarães 2012 European Capital of Culture

. Residents tend to have high expectations about the benefits of hosting a mega‐event. So, it was not surprising that the nomination of Guimarães, Portugal, as the 2012 European Capital of Culture (2012 ECOC) had raised great expectations in the local community towards its socio‐economic and cultural benefits. The present research was designed to examine the Guimarães residents’ perceptions on the impacts of hosting the 2012 ECOC approached in two different time schedules, the pre‐ and the post‐event, trying to capture the evolution of the residents` evaluation of its impacts. For getting the data, two surveys were applied to Guimarães` residents, one in the pre‐event phase, in 2011, and another in the post‐event phase, in 2013. This approach is uncommonly applied to Portugal data and it is even the first time it was done to a Portuguese European Capital of Culture. After a factor analysis, the results of t‐tests indicate that there were significant differences (p<0.05) between the samples from the pre‐ and post‐2012 ECOC on two positive impact factors (Community’ benefits and Residents’ benefits) and one negative impact factor (Economic, social and environmental costs). Respondents also showed a negative perception of the impacts in all dimensions, except Changes in habits of Guimarães residents. 

Reproduction of Leishmania (Leishmania ) infantum chagasi in conditioned cell culture growth medium

Leishmanias can be produced by inoculation in conditioned McCoy cell culture growth medium (CGM). Leishmania (Leishmania) infantum chagasi (100 parasites) grown in NNN medium was inoculated in 2.5 mL CGM, kept in plates (24 wells) and its multiplication was observed for five days (120 hours). After day 5, the medium was saturated with the flagellate forms of the parasite (promastigotes). The reproduction of the leishmanias was observed every 24 hours and the number of parasites was calculated by counting the parasites in a drop of 10 µ L and photomicrographied. So the number of Leishmanias was adjusted to 1 mL volume. The advantage of the technique by isolation of Leishmania in CGM demonstrated in this study is its low cost and high efficacy even with a small quantity of parasites (10² promastigotes) used as inoculum. Additionally, isolation of the leishmania can be obtained together with an increase in their density (180 times) as observed by growth kinetics, within a shorter time. These results justify the use of this low-cost technique for the isolation and investigation of the behavior and multiplication of Leishmania both in vertebrates and invertebrates, besides offering means of obtaining antigens, whether whole antigens (leishmanias) or the soluble antigens produced by the parasites which may be useful for the production of new diagnostic kits.

Kinetics of growth of Leishmania (Leishmania) chagasi cycle in McCoy cell culture

The kinetics of growth of Leishmania performed in vitro after internalization of the promastigote form in the cell and the occurrence of the transformation of the parasite into the amastigote form have been described by several authors. They used explants of macrophages in hamster spleen cell culture or in a human macrophage lineage cell, the U937. Using microscopy, the description of morphologic inter-relationship and the analysis of the production of specific molecules, it has been possible to define some of the peculiarities of the biology of the parasite. The present study shows the growth cycle of Leishmania chagasi during the observation of kinetic analysis undertaken with a McCoy cell lineage that lasted for a period of 144 hours. During the process, the morphologic transformation was revealed by indirect immunofluorescence (IF) and the molecules liberated in the extra cellular medium were observed by SDS-PAGE at 24-hour intervals during the whole 144-hour period. It was observed that in the first 72 hours the promastigote form of L. chagasi adhered to the cell membranes and assumed a rounded (amastigote-like) form. At 96 hours the infected cells showed morphologic alterations; at 120 hours the cells had liberated soluble fluorescent antigens into the extra cellular medium. At 144 hours, new elongated forms of the parasites, similar to promastigotes, were observed. In the SDS-PAGE, specific molecular weight proteins were observed at each point of the kinetic analysis showing that the McCoy cell imitates the macrophage and may be considered a useful model for the study of the infection of the Leishmania/cell binomial.

Bioelectrochemically-assisted reductive dechlorination of 1,2-dichloroethane by a Dehalococcoides-enriched microbial culture

The aim of this study was to verify the possibility to use a polarized graphite electrode as an electron donor for the reductive dechlorination of 1,2-dichloroethane, an ubiquitous groundwater contaminant. The rate of 1,2-DCA dechlorination almost linearly increased by decreasing the set cathode potential over a broad range of set cathode potentials (i.e., from −300 mV to −900 mV vs. the standard hydrogen electrode). This process was primarily dependent on electrolytic H2 generation. On the other hand, reductive dechlorination proceeded (although quite slowly) with a very high Coulombic efficiency (near 70%) at a set cathode potential of −300 mV, where no H2 production occurred. Under this condition, reductive dechlorination was likely driven by direct electron uptake from the surface of the polarized electrode. Taken as a whole, this study further extends the range of chlorinated contaminants which can be treated with bioelectrochemical systems.

ISO 9001 Quality Management Systems through the Lens of Organizational Culture

Both managers and scholars have convictions about the organizational approaches that best support organizational performance of the respective organizations and its Quality Management Systems. After a literature review of ISO 9001 Quality Management Systems (including the changes introduced by the 2015 edition), Organizational Culture theories are addressed and input from a CEO´s focus group was gathered. The importance of organizational culture for the success of Quality Management Systems and the achievement of the organizational desired results is highlighted. The article advances a proposal to analyze ISO 9001 International Standard through the lens of organizational culture theories identifying a stronger open systems approach (influence of the environment, dynamic perspective, need for survival) of the 2015 ISO 9001 edition when compared with the 2008 one. This provides additional knowledge both to scholars and practitioners for a better understanding of the culture issues that can maximize ISO 9001 Quality Management Systems 2015 edition contributions to organizational enduring success.

Comparison of direct immunofluorescence, conventional cell culture and polymerase chain reaction techniques for detecting respiratory syncytial virus in nasopharyngeal aspirates from infants

A total of 316 samples of nasopharyngeal aspirate from infants up to two years of age with acute respiratory-tract illnesses were processed for detection of respiratory syncytial virus (RSV) using three different techniques: viral isolation, direct immunofluorescence, and PCR. Of the samples, 36 (11.4%) were positive for RSV, considering the three techniques. PCR was the most sensitive technique, providing positive findings in 35/316 (11.1%) of the samples, followed by direct immunofluorescence (25/316, 7.9%) and viral isolation (20/315, 6.3%) (p < 0.001). A sample was positive by immunofluorescence and negative by PCR, and 11 (31.4%) were positive only by RT-PCR. We conclude that RT-PCR is more sensitive than IF and viral isolation to detect RSV in nasopharyngeal aspirate specimens in newborn and infants.

Immunoperoxidase technique using an anti-Leishmania (L.) chagasi hyperimmune serum in the diagnosis of culture-confirmed American tegumentary leishmaniasis

The present study reports the production of the rabbit anti-Leishmania (L.) chagasi hyperimmune serum, the standardization of the immunohistochemistry (IHC) technique and the evaluation of its employment in cutaneous leishmaniasis (CL) lesions diagnosed by Leishmania sp. culture isolation. Thirty fragments of active CL lesions were examined as well as 10 fragments of cutaneous mycosis lesions as control group. IHC proved more sensitive in detecting amastigotes than conventional hematoxylin-eosin (HE) stained slides: the former was positive in 24 (80%) biopsies whereas the latter, in 16 (53%) (p = 0.028). The reaction stained different fungus species causing cutaneous mycosis. Besides, positive reaction was noticed in mononuclear and endothelial cells. Nevertheless, this finding was present in the control group biopsies. It is concluded that IHC showed good sensitivity in detecting amastigotes.

No âmbito da unidade curricular Tese/Dissertação do 2ºano do Mestrado em Engenharia Eletrotécnica – Ramo Sistemas e Planeamento Industrial do Instituto Superior de Engenharia do Porto, o presente trabalho descreve o estágio curricular efetuado num projeto industrial de melhoria em parceria com o Kaizen Institute, uma empresa de consultoria operacional. Este projeto foi desenvolvido numa empresa de produção e redistribuição de artigos de papelaria e escritório, a Firmo AVS – Papeis e Papelaria,S.A.. O acordo efetuado entre o Kaizen Institute e a Firmo AVS foi o de promover e incutir a cultura da melhoria continua e da mudança de atitudes e comportamentos por parte dos colaboradores da Firmo, sendo que numa fase inicial o foco do projeto foi o departamento de produção de envelopes, designada por área piloto, expandindo-se posteriormente a metodologia Kaizen aos restantes departamentos. A realização deste projeto teve como objetivo a implementação de conceitos elementares de melhoria continua nomeadamente alguns pilares ou ferramentas do Total Flow Management (TFM) e do Kaizen Management System (KMS) na empresa Firmo, de forma a reduzir ou eliminar desperdícios, incremento do envolvimento dos colaboradores, melhoria da comunicação e trabalho em equipa, estandardização de processos produtivos, criação de normas de trabalho, utilização de ferramentas SMED para a redução de tempos improdutivos e aumento da produtividade. Várias foram as dificuldades presentes no terreno para a implementação destes objetivos mas com as diversas ferramentas e workshops realizados na organização, conseguiu-se o envolvimento de todos os colaboradores da organização e a obtenção de resultados satisfatórios nomeadamente ao nível da comunicação e trabalho em equipa, organização e limpeza dos postos de trabalho, standard work (normalização do trabalho), diminuição do lead time nos processos produtivos e consequente aumento de produtividade.

An organizational culture approach to performance in information technology micro-firms

This study aims to analyze and compare micro-firms’ organizational culture related to organizational performance. A case study methodology was used based on four firms, competitors among themselves in the Information Technology business, focusing on the years between 2008-2013. Findings pointed out many similarities to larger firms, but some specificities of micro-firms were found and propositions were defined: clan culture predominance is related to best performing micro-firms; the configuration of several culture types seemed to be the most suitable for obtaining good organizational results, provided that they do not focus only on hierarchy and market types of culture; the market culture predominance perception by employees is associated with low job satisfaction; and, after a certain time in business, micro-firms, as do larger companies, seek to standardize and control processes. Recognizing that organizational culture is considered important to firms’ results, this study sheds some light on that important factor for micro-firms.

Adenovirus respiratory infection: significant increase in diagnosis using PCR comparing with antigen detection and culture methods

Adenovirus (AdV) respiratory infections are usually described as being associated with high mortality rates. Laboratory diagnosis is essential for the establishment of the appropriate therapy, and for guiding the implementation of preventive measures in order to prevent the spread of the infection. Aiming to analyze the sensitivity and specificity of the laboratorial diagnosis methods available, we compared antigen detection by indirect immunofluorescence assay (IF), and a specific nested polymerase chain reaction (PCR), to detect AdV in respiratory samples collected from patients admitted to hospital with acute respiratory disease. Positive samples were inoculated into a cell culture to confirm the results. We analyzed 381 samples from the nasopharyngeal aspirates collected during the year 2008; of these, 2.6% tested were positive for adenovirus through IF and 10% through PCR; positive isolation was obtained in 40% and 26% of these cases, respectively. Most infected patients were children under six months of age, and despite of the fact that a significant number of patients required intensive care, the mortality rate was low (5%). In conclusion, molecular methods were found to be useful for rapid diagnosis of adenovirus infections with higher sensitivity than antigen detection; their introduction permitted a significant increase in diagnoses of adenovirus infections.

Assessment of physical impairments in leprosy patients: a comparison between the world health organization (who) disability grade and the Eye-Hand-Foot Score

This cross-sectional study assessed the grade of physical impairments in 61 individuals with leprosy receiving multidrug therapy (MDT) under the Brazilian Unified Health System (SUS), and residing in Campina Grande, Paraíba State, Brazil. Impairments were assessed using the disability grade (DG) standardized by the WHO, and the EHF score (Eye-Hand-Foot sum of impairment scores). Impairments were detected in 25 (41%) of the subjects. A total of 14 (23%) patients scored DG 1, while 11 (18%) were assigned DG 2. The EHF score ranged from 1 to 10 points in the group of patients with physical impairments, with a mean score of 3.6 points. The majority of individuals with impairments were affected in at least two sites. We conclude that the EHF score showed overlapping impairments in the segments examined and may be more appropriate than the DG classification system for describing the degree of physical impairment of leprosy patients.

A cultura organizacional e as competências de gestão dos líderes organizacionais: estudo de caso na Dorel Portugal

É sabido da importância que a cultura organizacional tem na competitividade das empresas e o papel que os líderes têm na definição e manutenção dessa cultura. O estudo de caso que aqui se apresenta pretende identificar a cultura organizacional e a congruência com as competências de gestão no contexto específico da Dorel Portugal, empresa do setor têxtil, de produção e fabrico de artigos para criança e bebé. Como referenciais teóricos, foram abordados os conceitos de cultura organizacional, de competências e de liderança, na perspetiva de autores como Schein (1999, 2004), Cameron (2004, 2011) e Quinn (1990, 2011). Participaram neste estudo de caso 43 colaboradores da Dorel Portugal, 6 deles são gestores de topo da organização. Em termos de metodologia foi seguida uma metodologia de estudo de caso e a recolha de dados para a sua análise efetivou-se através de uma pesquisa de campo in loco, com aplicação de questionários a todos os indivíduos sobre a cultura organizacional e as competências de gestão dos líderes, instrumentos baseados no Modelo dos Valores Contrastantes de Quinn e Rohrbaugh (1983) e entrevistas semi-estruturadas aos indivíduos com cargos de direção. Os resultados indicam que a perceção da cultura na organização estudada é predominantemente baseada na orientação para o Mercado, para o Clã e para a Hierarquia, existindo no entanto diferentes perceções de cultura (subculturas) por departamentos. Os resultados demonstraram que embora os líderes organizacionais mobilizem as suas competências de gestão de acordo com a cultura de empresa, segundo a auto avaliação e a perceção dos subordinados existem papéis nos quais devem alargar o seu leque de competências, essencialmente aqueles relativos às culturas de Clã e de Adocracia.

Implementação de ações estratégicas: participação dos alunos na vida da escola

O presente trabalho de projeto resulta de um estudo dos espaços de participação, dos alunos dos 2.º e 3.º ciclo do ensino básico, na vida da escola, permitindo a construção de um dispositivo de intervenção, que pretende implementar ações estratégicas que visem a ampliação desses espaços de participação. O seu desenvolvimento teórico assenta na necessidade da revitalização da cultura democrática participativa, através de uma maior e melhor participação. Neste campo, a escola, como lugar de interação quotidiana dos seus alunos, tem um papel importante a desempenhar na capacitação de uma participação ativa. Para tal urge a necessidade de implementação de ações estratégicas, em coerência com os documentos estruturantes da organização e de todos os seus órgãos de administração e gestão, de forma a instituir a mudança e a inovação na cultura de trabalho como um dos aspetos chave para o sucesso organizacional da escola. O trabalho de projeto foi realizado numa escola pública dos 2.º e 3.º ciclos e a amostra do estudo, foi composta por 401 alunos dos 2.º e 3.º ciclos e 31 professores Diretores de Turma. Os instrumentos de recolha de dados foram dois inquéritos por questionário, um para aplicar aos alunos, e outro aos Diretores de Turma, e a análise de conteúdo dos documentos orientadores da escola. Os resultados mostraram que os alunos possuem uma débil participação na vida da escola, quer ao nível dos documentos orientadores, quer na sua representação nos diferentes órgãos. No plano de ação, é apresentado um conjunto de propostas, que pretendem constituir-se como um dispositivo para colmatar esta debilidade.
