Assessment of groundwater contamination in an agricultural peri-urban area (NW Portugal): an integrated approach

The excessive use of pesticides and fertilisers in agriculture has generated a decrease in groundwater and surface water quality in many regions of the EU, constituting a hazard for human health and the environment. Besides, on-site sewage disposal is an important source of groundwater contamination in urban and peri-urban areas. The assessment of groundwater vulnerability to contamination is an important tool to fulfil the demands of EU Directives. The purpose of this study is to assess the groundwater vulnerability to contamination related mainly to agricultural activities in a peri-urban area (Vila do Conde, NW Portugal). The hydrogeological framework is characterised mainly by fissured granitic basement and sedimentary cover. Water samples were collected and analysed for temperature, pH, electrical conductivity, chloride, phosphate, nitrate and nitrite. An evaluation of groundwater vulnerability to contamination was applied (GOD-S, Pesticide DRASTIC-Fm, SINTACS and SI) and the potential nitrate contamination risk was assessed, both on a hydrogeological GIS-based mapping. A principal component analysis was performed to characterised patterns of relationship among groundwater contamination, vulnerability, and the hydrogeological setting assessed. Levels of nitrate above legislation limits were detected in 75 % of the samples analysed. Alluvia units showed the highest nitrate concentrations and also the highest vulnerability and risk. Nitrate contamination is a serious problem affecting groundwater, particularly shallow aquifers, especially due to agriculture activities, livestock and cesspools. GIS-based cartography provided an accurate way to improve knowledge on water circulation models and global functioning of local aquifer systems. Finally, this study highlights the adequacy of an integrated approach, combining hydrogeochemical data, vulnerability assessments and multivariate analysis, to understand groundwater processes in peri-urban areas.

The relationship between knowledge acquisition on international assignments and career development: an exploratory study with portuguese repatriates

This paper explores the relationship between the expatriates’ knowledge acquisition (KA) and their career development after an international assignment (IA). The purpose of this paper is to examine the role of expatriates in KA and transfer within International Portuguese multinational corporations. Furthermore, with this empirical study we try to analyse how the knowledge that is acquired and transferred translates into a basis for career development after the IA. This phenomenon has a special relevance in the Portuguese context, because this country is known a growing process of globalization in recent years. Furthermore, (a) there are no empirical studies concerning knowledge transfer and career development of repatriates from Portuguese companies; (b) little is known about the repatriates’ contributions to their home company after IA. This paper is one of the first to focus specifically on the repatriates’ role in KA and transfer from the host company to their Portuguese home company. A qualitative research methodology is used, specifically through an exploratory case study approach, which examines how knowledge management (KM) acquisition or transferring during IA are important for the repatriates’ career development in the Portuguese home company. Data were collected through semi-structured interviews to 42 Portuguese international assignees and 18 organizational representatives from nine Portuguese companies. Preliminary results show that KA and transfer made by Portuguese expatriates contributes directly to their career development. Moreover, evidence reveals that not all repatriates were promoted after their IA; rather some repatriates were even demoted after their IA. Furthermore, the results obtained suggest that the type of knowledge which acquired or transferred plays a central role in the career development after repatriation. According to these results, the paper discusses the major theoretical and practical implications. Suggestions for future research are also presented.

Neurotoxic activity and ultrastructural changes in muscles caused by the brown widow spider Latrodectus geometricus venom

Brown widow spider (Latrodectus geometricus) venom (BrWSV) produces few local lesions and intense systemic reactions such as cramps, harsh muscle pains, nausea, vomiting and hypertension. Approximately 16 protein bands under reducing conditions and ~ 14 bands under non-reducing conditions on a 12.5% sodium dodecyl sulfate-polyacrylamide gel electrophoresis were observed. Neurotoxic clinical manifestations were confirmed in vivo, while proteolytic activity was demonstrated on gelatine film. Severe ultrastructural damages in mice skeletal muscles were observed at 3, 6, 12 and 24 h postinjection with at total of 45 µg of venom protein. Infiltration of eosinophils and ruptures of the cellular membranes were observed in the muscles along with swelling of the nuclear cover and interruption of the collagen periodicity. Altered mitochondrias and autophage vacuoles, nuclear indentation and mitochondria without cristae, slight increment of intermyofibrillar and subsarcolemic spaces and myelinic figures formation were also observed. In the capillary, endothelial membrane unfolding into the lumen was noticed; along with myelinic figures compatible with a toxic myopathy. Swollen sarcotubular systems with lysis of membrane, intense mitochondria autophagia and areas without pinocytic vesicles were observed. Swollen mitochondria surrounded by necrotic areas, myofibrillar disorganization and big vacuolas of the sarcotubular system, degenerated mitochondrium with formation of myelinic figure was seen. Glycogenosomes with small particulate, muscle type glycogen was noticed. Autophagic vacuole (autophagolysosomes) and necrotic areas were also noticed. These damages may be due to interactive effects of the multifactorial action of venom components. However, Latrodectus geometricus venom molecules may also be utilized as neuro therapeutic tools, as they affect neuronal activities with high affinity and selectivity. To our knowledge, the present study is the first ultrastructural report in the literature of muscle injuries and neurological and proteolytic activities caused by BrWSV.

Cutting path as a rural postman problem

The Rural Postman Problem (RPP) is a particular Arc Routing Problem (ARP) which consists of determining a minimum cost circuit on a graph so that a given subset of required edges is traversed. The RPP is an NP-hard problem with significant real-life applications. This paper introduces an original approach based on Memetic Algorithms - the MARP algorithm - to solve the RPP and, also deals with an interesting Industrial Application, which focuses on the path optimization for component cutting operations. Memetic Algorithms are a class of Metaheuristics which may be seen as a population strategy that involves cooperation and competition processes between population elements and integrates “social knowledge”, using a local search procedure. The MARP algorithm is tested with different groups of instances and the results are compared with those gathered from other publications. MARP is also used in the context of various real-life applications.

Effects of a mental health training program on health care worker's knowledge and attitude and practice in Belize

ABSTRACT This study was conducted to assess mental health knowledge, attitude and practices among health care workers in Belize before and immediately after a competency based training program in mental health. A baseline Knowledge, Attitudes and Practices (KAP) survey was given to health personnel, mainly nurses, working primary and secondary care. The intervention was a 13-week face-to-face training course for health care professionals with the objective of increasing their competency in mental health and reducing stigma. After the training a post intervention KAP survey was conducted among the original respondents. 88 health care workers completed the baseline survey and 61 of those respondents completed the post-intervention questionnaire. The results showed that the level of knowledge of the participants had improved by the training intervention and that in general, the intervention was effective in correcting some misconceptions about mental illness and reducing stigmatizing attitudes among the participants.

Knowledge repository framework for crowdsourcing innovation intermediary: a proposal

A crowdsourcing innovation intermediary performs mediation activities between companies that have a problem to solve or that seek a business opportunity, and a group of people motivated to present ideas based on their knowledge, experience and wisdom, taking advantage of technology sharing and collaboration emerging from Web2.0. As far as we know, most of the present intermediaries don´t have, yet, an integrated vision that combines the creation of value through community development, brokering and technology transfer. In this paper we present a proposal of a knowledge repository framework for crowdsourcing innovation that enables effective support and integration of the activities developed in the process of value creation (community building, brokering and technology transfer), modeled using ontology engineering methods.

Contributo das organizações do terceiro setor no desenvolvimento dos países de píngua pficial portuguesa

O empreendedorismo social é um campo que tem vindo a ganhar uma importância crescente nas sociedades atuais, sendo reconhecido como uma ferramenta útil na promoção do desenvolvimento sustentável. Como se trata de um campo emergente, apresenta-se ainda pouco explorado. Em Cabo Verde não existem ainda estudos sobre o tema, embora existam já algumas iniciativas de empreendedorismo social. A investigação foi desenvolvida de forma a responder ao objetivo de se conhecer qual o contributo que as Organizações Não Governamentais para o Desenvolvimento (ONGD) portuguesas têm dado para a sedimentação do empreendedorismo social em Cabo Verde. Assim, procurou-se apurar e analisar as ONGD que desenvolvem projetos em Cabo Verde, as áreas em que estas atuam para promoverem o desenvolvimento economico-social, os meios de financiamentos a que recorrem, as dificuldades encontradas no desenvolvimento das suas atividades, bem como compreender a razão que levou a que Cabo Verde fosse beneficiado com as ações dessas ONGD. Para conseguir atingir estas metas recorreu-se à metodologia qualitativa onde se fez uma análise exploratória e descritiva. A técnica utilizada para a recolha da informação primária foi a entrevista dirigida aos responsáveis de seis ONGD portuguesas que atuam em Cabo Verde, nomeadamente a Associação para a Cooperação Entre os Povos, a Associação de Defesa do Património de Mértola, Instituto Marquês de Valle Flôr, Meninos do Mundo, Terras Dentro e a Associação Raia Histórica. Os resultados deste estudo permitiram identificar que as ONGD portuguesas agem impulsionando o empreendedorismo social em Cabo Verde através da promoção do desenvolvimento integrado e sustentável, apoiado em parcerias estabelecidas com outras organizações locais caboverdeanas. Estes parceiros são atores chave que estão no terreno e possuem o conhecimento da realidade do país. Cabo Verde foi beneficiado pelos projetos por pertencer aos Países Africanos de Língua Oficial Portuguesa e/ou à Comunidade dos Países de Língua Portuguesa. Na obtenção de recursos, a maioria das ONGD portuguesas recorre a recursos em espécie e a voluntários portugueses, desempenhando estes o papel de formadores. A geração de valor social por parte destas entidades é feita muitas vezes de uma forma indireta, através da criação de valor económico que depois se repercute em valor social. Este valor social resulta da sua atuação em várias áreas como a saúde e segurança alimentar, desenvolvimento rural, meio ambiente, educação e formação profissional, emprego, economia alternativa ou microcrédito, pobreza e exclusão social, ambiente, habitação, promoção social e do turismo, capacitação e reforço institucional e coerência das políticas públicas para o desenvolvimento. Sendo Cabo Verde um arquipélago, as principais dificuldades encontradas pelas ONGD na sua atuação prende-se com a acessibilidade às ilhas devido à falta de transportes e meios de comunicação.
