The impact of global forces on the individual: empirical evidence from the German clothing industry

Starting from theoretical perspectives on globalisation, the following article analyses how current working conditions are affected by globalisation processes. For this purpose, recent developments in the German clothing sector are traced back to the power of economic globalisation processes. Characterising the German clothing sector as pioneer in economic globalisation, we use empirical findings to illustrate how current processes of globalisation influence the work place: At organisational level, corporate strategies aim at rationalisation, standardisation and flexibilisation of work in order to response to the economic pressure of global markets. At individual level these strategies, in turn, speed up working processes and intensify working processes for the employees. Although these developments form strong trends, we conclude that the local embeddedness of companies is still of high importance with regard to organisational and individual consequences of globalisation.

Psychometric Properties of the Portuguese Version of the Posttraumatic Growth Inventory Short Form Among Divorced Adults

The aim of this study was to develop and validate a Portuguese version of the Short Form of the Posttraumatic Growth Inventory (PTGI-SF). Using an online convenience sample of Portuguese divorced adults (N = 482), we confirmed the oblique five-factor structure of the PTGI-SF by confirmatory factor analysis. The results demonstrated the measurement invariance across divorce initiator status groups. Total score and factors of PTGI-SF showed good internal consistency, with the exception of the New Possibilities factor, which revealed an acceptable reliability. The Portuguese PTGI-SF showed a satisfactory convergent validity. In terms of discriminant validity, posttraumatic growth assessed by the Portuguese PTGI-SF was a distinct factor from posttraumatic psychological adjustment. These preliminary findings suggest the cultural adaptation and also psychometric properties of the present Portuguese PTGI-SF to measure posttraumatic growth after personal crisis.

Paracoccidioides brasilienses isolates obtained from patients with acute and chronic disease exhibit morphological differences after animal passage

The basis for virulence in Paracoccidioides brasiliensis is not completely understood. There is a consensus that the sequencial in vitro subcultivation of P. brasiliensis leads to loss of its pathogenicity, which can be reverted by reisolation from animal passage. Attention to morphological and biochemical properties that are regained or demonstrated after animal passage may provide new insights into factors related to the pathogenicity and virulence of P. brasiliensis. We evaluated morphological characters: the percentage of budding cells, number of buds by cell and the diameter of 100 mother cells of yeast-like cells of 30 P. brasiliensis isolates, before and after animal passage. The isolates were obtained from patients with different clinical forms of paracoccidioidomycosis (PCM): acute form (group A, n=15) and chronic form (group C, n=15). The measurement of the yeast cell sizes was carried out with the aid of an Olympus CBB microscope coupled with a micrometer disc. We measured the major transverse and longitudinal axes of 100 viable cells of each preparation. The percentage of budding cells as also the number of buds by cell was not influenced by animal passage, regardless of the source of the strain (acute or chronic groups). The size values of P. brasiliensis isolates from groups A and C, measured before the animal passage exhibited the same behavior. After animal passage, there was a statistically significant difference between the cell sizes of P. brasiliensis isolates recovered from testicles inoculated with strains from groups A and C. The maximum diameter of mother cells from group A isolates exhibited a size of 42.1mm in contrast with 32.9mm exhibited by mother cells from group C (p<0.05). The diameter of 1500 mother cells from group A isolates exhibited a medium size of 16.0mm (SD ± 4.0), a value significantly higher than the 14.1mm (SD = ± 3.3) exhibited by 1500 mother cells from group C isolates (p<0.05). Our results reinforce the polymorphism exhibited by P. brasiliensis in biological material and the need for further investigations to elucidate the role of morphological parameters of the fungus in the natural history of the disease.

Effect of active components from Garlic on AGEs formation

Advanced glycation end-products are Maillard reaction products that are found in thermal processed food. This compounds are often referred as unhealthy for human diet, namely because of their capacity to form amino-acid dimers. There is a broad range of answers to get about how these products are formed, how they interact with the organism and how these reactions can be inhibited to prevent the referred effects. Some compounds from garlic are thought to be able to inhibit these reactions. This study using spectrophotometric, High Performance Liquid Chromatography-Tandem Mass Spectrometry (HPLC-MS/MS) and Fourier transformed infrared spectroscopy (FTIR) analysis, helps to understand better not only not only the effect of some compounds obtained from garlic, diallyl sulfide (DAS), diallyl disulfide (DADS) and diallyl trisulfide (DATS), on these AGEs production reaction, but also helped to understand better the reaction itself.

Hoje em dia, com os avanços constantes na indústria, novas áreas começam cada vez mais a ser foco de atenção por parte das organizações. Motivados pela procura de melhores condições para os seus colaboradores e por todos os benefícios que este tipo de intervenção oferece, tanto a curto, como principalmente a médio e longo prazo, a Grohe Portugal, mais especificamente o seu departamento de montagem, achou relevante potenciar a aplicação da Ergonomia nos seus postos de trabalho. Posto isto, esta dissertação pretende apresentar o trabalho desenvolvido junto da organização que teve como objetivo projetar e executar uma linha de montagem que tivesse em consideração os seguintes aspetos: • Ergonomia; • Automatização ou semi-automatização de operações; • Simplificação de aspetos operacionais; • Sistemas de abastecimento mais robustos e de fácil uso; • Simplificação de setups; • Definição de dimensões normalizadas para futuros projetos. As soluções encontradas tiveram como objetivo primordial satisfazer o maior número possível de colaboradores, sendo que para tal foram utilizados dados referentes a antropometria da população Portuguesa. Para a realização e conclusão deste projeto, o trabalho foi decomposto em varias etapas, de entre as quais se destacam: • Analise e estudo dos métodos de montagem; • Levantamento de todos os componentes e operações que constituem o processo de fabrico das diversas famílias onde foram implementados novos projetos; • Definição e uniformização da estrutura das novas linhas de montagem; • Estudo e definição da disposição dos componentes na nova linha, bem como da sua forma de abastecimento; • Projeto da linha de montagem em 3D com recurso ao software SolidWorks (DassaultSystemes, 2014); • Montagem final da linha, bem como o acompanhamento da sua fase de arranque. Durante o estagio foi ainda pensado e implementado um projeto paralelo com vista a constante manutenção e melhoria do departamento de montagem cujo objetivo, através de “plant walks”, e detetar de entre outras, situações de falta de identificação de componentes ou equipamentos, degradação de ferramentas, fugas ou derrames nas linhas, etc. O balanco final do trabalho foi bastante positivo, tendo-se alcançado melhorias em alguns índices de qualidade, tempos de abastecimento e condições ergonómicas dos postos de trabalho que sofreram intervenção, tendo essas melhorias resultado numa avaliação positiva por parte dos colaboradores que integram essas mesmas linhas.

Efeitos imediatos da técnica de desrotação do atlas de Rocabado e do SNAG C1/2 de Mulligan na amplitude do teste de flexão-rotação em indíviduos com cefaleia cervicogénica : um ensaio clínico aleatório

RESUMO: A cefaleia cervicogénica é uma forma comum de dor de cabeça, que tem sido associada à existência de uma disfunção das estruturas da coluna cervical superior. Estudos recentes mostram uma grande incidência dessa disfunção a nível de C1-C2, avaliada pelo teste de flexão-rotação. Vários terapeutas manuais, como Brian Mulligan e Mariano Rocabado, têm sido sugerido técnicas de tratamento para este tipo de disfunção. Contudo, a evidência acerca da efectividade dessas técnicas é escassa. Desenho do estudo: Foi efectuado um ensaio clínico aleatório, duplamente cego, composto por três fases: pré-intervenção, intervenção e pós-intervenção. Objectivos: Avaliar e comparar os efeitos imediatos de duas técnicas de Terapia Manual Ortopédica (SNAG C1/2 de Mulligan e técnica de desrotação do atlas de Rocabado), na amplitude de movimento de rotação do segmento vertebral C1-C2, em indivíduos com história de cefaleia cervicogénica e com limitação no teste de flexão-rotação. As técnicas de tratamento foram usadas de forma isolada, em comparação a um grupo placebo. Métodos: Uma amostra de 60 indivíduos, com cefaleia cervicogénica e limitação do teste de flexão-rotação, foram aleatoriamente distribuídos por três grupos: SNAG C1/2 de Mulligan, técnica de desrotação do atlas de Rocabado e grupo placebo. O outcome primário foi a amplitude de movimento obtida no teste de flexão-rotação, que foi medido antes e imediatamente após a intervenção. Resultados: Imediatamente após a intervenção, a amplitude verificada no teste de flexão-rotação aumentou 21.8º (DP, 4.68) no grupo submetido ao SNAG C1/2 de Mulligan, 15º (DP, 5.07) no grupo em que foi aplicada a técnica de desrotação do atlas de Rocabado e 0.65º (DP, 0.67) no grupo placebo. Uma ANOVA modelo misto, 2 por 3, revelou efeito principal significativo do tempo (p<.001) e grupo (p<.001), assim como uma interacção significativa entre grupo e tempo (p<.001), relativamente à variável amplitude do teste de flexão-rotação. Estes resultados indicam que as diferenças verificadas entre os grupos eram dependentes do momento de avaliação. Uma comparação múltipla post hoc revelou que quer as técnicas de Mulligan, quer de Rocabado, produziram efeitos significativamente maiores que a intervenção placebo na amplitude de movimento do teste de flexão-rotação (p<.001 e p=.001, respectivamente). No entanto,não se verificou uma diferença significativa no que diz respeito à efectividade de ambas as técnicas de Terapia Manual Ortopédica aplicadas (p=.42). Conclusão: Esta investigação sugere que as duas técnicas de Terapia Manual Ortopédica avaliadas produziram efeito clínica e estatisticamente significativo na amplitude do teste de flexão-rotação. No entanto, não se verificaram diferenças entre as duas técnicas, no que diz respeito ao seu efeito no ganho de amplitude de movimento. Os resultados obtidos fornecem evidência preliminar sobre a efectividade de ambas as intervenções no tratamento da redução de amplitude de movimento em indivíduos com história de cefaleia cervicogénica.-------------------------------ABSTRACT:Background: Cervicogenic headache is a common form of headache arising from dysfunction in structures of the upper cervical spine. Recent studies have shown a high incidence of C1/2 dysfunction, evaluated by the flexion-rotation test (FRT). Several manual therapists have suggested different approaches to manage that dysfunction, such as Brian Mulligan and Mariano Rocabado. However, the evidence of the effectiveness of those manual techniques is anedoctal. Design: Randomized double blinded controlled trial with three phases: pre-intervention, intervention and post-intervention. Objectives: To determine and compare the immediate effects of two manual therapy techniques (Mulligan’s SNAG C1/2 and Rocabado’s atlas’ derotation technique) in the range of motion of C1-C2 vertebral segments, in cervicogenic headache patients and with limitation on the flexion-rotatoin test. The treatment techniques were used as single treatments against a placebo group. Methods: A sample of 60 subjects with cervicogenic headache and FRT limitation were randomly allocated into one of three groups: Mulligan’s C1/2 SNAG, Rocabado’s atlas derotation technique or placebo group. The primary outcome was the flexion rotation test range, which was measured before and immediately after the intervention. Results: Immediately after the application of the interventions, FRT range increased by 21.8º (SD, 4.68) for the Mulligan’s C1-2 SNAG group, 15º (SD, 5.07) for the Rocabado’s atlas derotation technique and 0.65º (SD, 0.67) for the placebo group. A 2-by-3 mixedmodel ANOVA a significant main effect of time (p<.001) and group (p<.001), as well as a significant interaction between group and time (p<.001) for the variable FRT range. These results indicate that group differences were dependent on time. A pairwise post hoc comparison revelad that both the Mulligan and Rocabado techniques produced significantly more effect on FRT range of motion than the placebo intervention (p<.001 and p=.001, respectively). However, there was not a significant difference between the effectiveness of the two manual therapy techniques (p=.42).Conclusion: This investigation’s findings suggest that both Mulligan’s C1/2 SNAG and Rocabado’s atlas derotation techniques produced a clinically and statistically significant effect on FRT range, but there were no changes between the two techniques in their effectiveness. These results provide preliminary evidence for the efficacy of both manual therapy techniques in the management of individuals with cervicogenic headache and FRT limitation.

Questing one Brazilian query: reporting 16 cases of Q fever from Minas Gerais, Brazil

Q fever has been considered non-existing in Brazil where reports of clinical cases still cannot be found. This case-series of 16 patients is a result of a systematic search for such illness by means of clinical and serologic criteria. Serologic testing was performed by the indirect microimmunofluorescence technique using phase I/II C. burnetii antigens. Influenza-like syndrome was the most frequent clinical form (eight cases - 50%), followed by pneumonia, FUO (fever of unknown origin), mono-like syndrome (two cases - 12.5% each), lymphadenitis (one case - 6.3%) and spondylodiscitis associated with osteomyelitis (one case - 6.3%). The ages varied from four to 67 years old with a median of 43.5. All but one patient had positive serologic tests for phase II IgG whether or not associated with IgM positivity compatible with acute infection. One patient had both phase I and phase II IgG antibodies compatible with chronic Q fever. Seroconvertion was detected in 10 patients. Despite the known limitations of serologic diagnosis, the cases here reported should encourage Brazilian doctors to include Q fever as an indigenous cause of febrile illness.

BIWiki - Using a Business Intelligence Wiki to Form a Virtual Community of Practice for Portuguese Master's Students

Web 2.0 software in general and wikis in particular have been receiving growing attention as they constitute new and powerful tools, capable of supporting information sharing, creation of knowledge and a wide range of collaborative processes and learning activities. This paper introduces briefly some of the new opportunities made possible by Web 2.0 or the social Internet, focusing on those offered by the use of wikis as learning spaces. A wiki allows documents to be created, edited and shared on a group basis; it has a very easy and efficient markup language, using a simple Web browser. One of the most important characteristics of wiki technology is the ease with which pages are created and edited. The facility for wiki content to be edited by its users means that its pages and structure form a dynamic entity, in permanent evolution, where users can insert new ideas, supplement previously existing information and correct errors and typos in a document at any time, up to the agreed final version. This paper explores wikis as a collaborative learning and knowledge-building space and its potential for supporting Virtual Communities of Practice (VCoPs). In the academic years (2007/8 and 2008/9), students of the Business Intelligence module at the Master's programme of studies on Knowledge Management and Business Intelligence at Instituto Superior de Estatistica e Gestao de Informacao of the Universidade Nova de Lisboa, Portugal, have been actively involved in the creation of BIWiki - a wiki for Business Intelligence in the Portuguese language. Based on usage patterns and feedback from students participating in this experience, some conclusions are drawn regarding the potential of this technology to support the emergence of VCoPs; some provisional suggestions will be made regarding the use of wikis to support information sharing, knowledge creation and transfer and collaborative learning in Higher Education.

A comparison between thin film solar cells made from co-evaporated CuIn1-xGaxSe2using a one-stage process versus a three-stage process

Until this day, the most efficient Cu(In,Ga)Se2 thin film solar cells have been prepared using a rather complex growth process often referred to as three-stage or multistage. This family of processes is mainly characterized by a first step deposited with only In, Ga and Se flux to form a first layer. Cu is added in a second step until the film becomes slightly Cu-rich, where-after the film is converted to its final Cu-poor composition by a third stage, again with no or very little addition of Cu. In this paper, a comparison between solar cells prepared with the three-stage process and a one-stage/in-line process with the same composition, thickness, and solar cell stack is made. The one-stage process is easier to be used in an industrial scale and do not have Cu-rich transitions. The samples were analyzed using glow discharge optical emission spectroscopy, scanning electron microscopy, X-ray diffraction, current–voltage-temperature, capacitance-voltage, external quantum efficiency, transmission/reflection, and photoluminescence. It was concluded that in spite of differences in the texturing, morphology and Ga gradient, the electrical performance of the two types of samples is quite similar as demonstrated by the similar J–V behavior, quantum spectral response, and the estimated recombination losses.

Evaluation of three different DNA extraction methods from blood samples collected in dried filter paper in Plasmodium subpatent infections from the Amazon region in Brazil

Asymptomatic Plasmodium infection is a new challenge for public health in the American region. The polymerase chain reaction (PCR) is the best method for diagnosing subpatent parasitemias. In endemic areas, blood collection is hampered by geographical distances and deficient transport and storage conditions of the samples. Because DNA extraction from blood collected on filter paper is an efficient method for molecular studies in high parasitemic individuals, we investigated whether the technique could be an alternative for Plasmodium diagnosis among asymptomatic and pauciparasitemic subjects. In this report we compared three different methods (Chelex®-saponin, methanol and TRIS-EDTA) of DNA extraction from blood collected on filter paper from asymptomatic Plasmodium-infected individuals. Polymerase chain reaction assays for detection of Plasmodium species showed the best results when the Chelex®-saponin method was used. Even though the sensitivity of detection was approximately 66% and 31% for P. falciparum and P. vivax, respectively, this method did not show the effectiveness in DNA extraction required for molecular diagnosis of Plasmodium. The development of better methods for extracting DNA from blood collected on filter paper is important for the diagnosis of subpatent malarial infections in remote areas and would contribute to establishing the epidemiology of this form of infection.
