Practices and trends of telework in the Portuguese industry: the results of surveys in the textile, metal and software sectors

The aim of the TeleRisk Project on labour relations and professional risks within the context of teleworking in Portugal – supported by IDICT – Institute for Development and Inspection of Working Conditions (Ministry of Labour), is to study the practices and forms of teleworking in the manufacturing sectors in Portugal. The project chose also the software industry as a reference sector, even though it does not intend to exclude from the study any other sector of activity or the so-called “hybrid” forms of work. However, the latter must have some of the characteristics of telework. The project thus takes into account the so-called “traditional” sectors of activity, namely textile and machinery and metal engineering (machinery and equipment), not usually associated to this type of work. However, telework could include, in the so-called “traditional” sectors, other variations that are not found in technologically based sectors. One of the evaluation methods for the dynamics associated to telework consisted in carrying out surveys by means of questionnaires, aimed at employers in the sectors analysed. This paper presents some of the results of those surveys. It is important to mention that, being a preliminary analysis, it means that it does not pretend to have exhausted all the issues in the survey, but has meant that it shows the bigger tendencies, in terms of teleworking practices, of the Portuguese industry.

The paper also highlights major current trends, drivers of change and future prospects in this sector.

International partner selection Indian technical textile market

Due to a combination of a vast agricultural industry and a tremendously growing technical textile industry, Ludvig Svensson identified India as target market for possible expansion through domestic production and supply. However, Svensson needed additional information about the industry structure and key players. Therefore, this project focused on a detailed analysis of the technical textile market and its players by following the international partner selection process. Thereby, five key players were identified as potential partners, as well as the need for additional research to determine alternative entry modes, as the market does not currently seem to be receptive for Svensson products.

Genetic and functional analysis of the bacillus subtilis BSP1 gam cluster

Mannans (linear mannan, glucomannan, galactomannan and galactoglucomannan) are the major constituents of the hemicellulose fraction in softwoods and show great importance as a renewable resource for fuel or feedstock applications. As complex polysaccharides, mannans can only be degraded through a synergistic action of different mannan-degrading enzymes, mannanases. Microbial mannanases are mainly extracellular enzymes that can act in wide range of pH and temperature, contributing to pulp and paper, pharmaceutical, food and feed, oil and textile successful industrial applications. Knowing and controlling these microbial mannan-degrading enzymes are essential to take advantage of their great biotechnological potential. The genome of the laboratory 168 strain of Bacillus subtilis carries genes gmuA-G dedicated to the degradation and utilization of glucomannan, including an extracellular -mannanase. Recently, the genome sequence of an undomesticated strain of B. subtilis, BSP1, was determined. In BSP1, the gmuA-G operon is maintained, interestingly, however, a second cluster of genes was found (gam cluster), which comprise a second putative extracellular β-mannanase, and most likely specify a system for the degradation and utilization of a different mannan polymer, galactoglucomannan. The genetic organization and function of the gam cluster, and whether its presence in BSP1 strain results in new hemicellulolytic capabilities, compared to those of the laboratory strain, was address in this work. In silico and in vivo mRNA analyses performed in this study revealed that the gam cluster, comprising nine genes, is organized and expressed in at least six different transcriptional units. Furthermore, cloning, expression, and production of Bbsp2923 in Escherichia coli was achieved and preliminary characterization shows that the enzyme is indeed a β-mannanase. Finally, the high hemicellulolytic capacity of the undomesticated B. subtilis BSP1, demonstrated in this work by qualitative analyses, suggests potential to be used in the food and feed industries.

Ética e Responsabilidade Social Empresarial – A contribuição das empresas na promoção da equidade e da justiça social: análise a partir da experiência de algumas empresas do setor têxtil do Norte de Minas – MG – Brasil

Os efeitos da mundialização do capital e as implicações do neoliberalismo reconfiguraram os mercados e geraram alterações no comportamento dos indivíduos. Esses novos cenários de produção do social alteram as definições dos papéis dos atores tradicionais e conduzem-nos ao questionamento do sentido das suas ações. Assim, interessa-nos, particularmente, analisar a corresponsabilidade das empresas no desenvolvimento social e humano e no processo de transformação social. Essa reflexão obriga-nos a tecer considerações sobre a definição do estatuto económico das empresas e as suas finalidades éticas, ou a articulação entre, por um lado, os constrangimentos de gestão que pesam sobre as empresas a curto prazo e o plano singular e, por outro lado, as suas funções económicas a médio e a longo prazo e o plano do conjunto da sociedade. Esta discussão tem sido feita dentro dos esforços de teorização sobre a “responsabilidade social das empresas” (RSE). O presente estudo busca contribuir para uma discussão sobre o significado desta responsabilidade. Para tal, fizemos um inventário das dimensões associadas na literatura às práticas de RSE a partir das quais construímos uma tipologia das diferentes modalidades de responsabilidade que podem ser invocadas. Procurámos perceber como, e em que medida, as dimensões em que são promovidas como marcas da responsabilidade social das empresas se encontram distribuídas em tecidos económicos comuns, ou seja, tecidos económicos significativos de um ponto de vista intencional ou compreensivo e representativos, ao mesmo tempo, no plano extensivo, de práticas responsáveis nos planos da equidade e da justiça social. Esta orientação justifica-se pelo facto de, para além do conhecimento de práticas emblemáticas, o nosso estudo visa a compreensão de contextos socioeconómicos marcados por grandes disparidades na distribuição dos indicadores de equidade económica e de justiça social e onde, portanto, práticas empresariais responsáveis poderiam ter um significado e um efeito importantes na perspetiva da transformação das situações. Na realização da pesquisa empírica, optámos pela região Norte de Minas Gerais, no Brasil. Optámos, ainda, pelo setor do téxtil, tendo em conta: a sua importância para a região; a sua interdependência entre níveis de responsabilidade diferentes; a grande abrangência das atividades económicas envolvidas; a distribuição da atividade por empresas de diferentes dimensões e escalas e o número importante de trabalhadores abrangidos. Esta escolha do setor e do território possibilitou a consideração de diferentes vetores de análise: os modos de produção; as dimensões de empresas; os níveis de implicação no processo de globalização; os modos de inserção na economia; os setores implicados na cadeia produtiva; os tipos de trabalho – responsável e irresponsável. Neste estudo, procura-se identificar as práticas responsáveis, de acordo com a tipologia que construímos, com intuito de elencar quais têm sido as boas (ou más) práticas das empresas no Norte de Minas na perspetiva da RSE. Isto significa que, em oposição às modalidades de prática que se ajustam à definição de RSE, se perfilam outras que não obedecem aos critérios da certificação, existindo ainda muitas que poderemos considerar de irresponsabilidade, à luz dos valores éticos e de justiça social promovidos pelo label RSE.

Fuel switching

The present Master dissertation is a project whose main objective is to identify value creation opportunities through fuel switching in the Portuguese industry, services, agriculture and fishing sectors. Fuel switching opportunities are characterized by type of fuel transition, type of technology transition, economy subsectors prone to have fuel switching and value created through fuel shift. Results suggest tomato concentrate, dairy, beer manufacturing and sugar refining subsectors is where prevalence of fuel oil steam boilers is high, for such cases conversion to natural gas steam boilers should result in operations having a ratio of NPV over CAPEX larger than ten and a payback period just under one year. Results further suggest food, beverages, textile, chemicals and wood subsectors currently operate between ten and twenty cogeneration Diesel engines that can be either modified to operate with natural gas or replaced by new natural gas cogeneration systems. Financial modeling indicates that both options have great value creation potential. The current analysis aims to be used by natural gas suppliers and energy project promoters to identify new potential deals as well as by heavy energy consumers to mitigate their energy related costs.
