Knowledge and attitudes of nurses towards alcohol and related problems: the impact of an educational intervention

An exploratory study of quasi-experimental approach that aimed to verify the impact of an educational intervention on attitudes and knowledge of nurses towards alcohol use and associated problems. The sample included 185 nurses, divided into two groups: 84 submitted to a training course and formed the experimental group. Data were collected through a knowledge survey and an attitude scale. The attitudes of the participants of both groups were positive. There were no significant differences between groups in relation to knowledge. The strongest predictors of positive attitudes were possessed preparation to act with chemical dependents (OR = 2.18), "have received increased workload during graduation on the theme, 'alcohol and other drugs'" (OR = 1.70), and "completed graduate school" (OR = 2.59). The educational intervention had a positive impact on the attitudes of nurses towards alcoholics, work and interpersonal relationships with such clientele.

All materials should be delivered with the proper certifications, invoices, or bill of lading. These records should indicate when the shipment arrived, the amount and identification of material delivered, and the laboratory report certification number, invoice number, and ticket number.

Health problems of nursing workers in a public educational institution

Objective: To identify the issues occurred with nursing workers through a Health Monitoring System for Nursing Workers (SIMOSTE) and to describe the consequences of those problems. Method: This is a quantitative, exploratory and descriptive study realized in a teaching hospital in the west region of the city of São Paulo. Results: From the SIMOSTE, 1.847 occurrences were registered in a six month period. Within the main occurrences, medical licenses, work related accidents with and without removals; psychiatric consultations and psychotherapy were highlighted. Conclusion: The data points out to the need for the development of new health vigilance actions to notify accidents and illness related to work, besides the prevention of issues. 


STRATEGIES TO SURPASS THE VULNERABILITY OF THE SMALL ISLAND STATES WITH FEW RESOURCES: THE CASE OF CAPE VERDE

The problem of small Island Developing States (SIDS) is quite recent, end of the 80s and 90s, still looking for a theoretical consolidation. SIDS, as small states in development, formed by one or several islands geographically dispersed, present reduced population, market, territory, natural resources, including drinkable water, and, in great number of the cases, low level of economic activity, factors that together, hinder the gathering of scale economies. To these diseconomies they come to join the more elevated costs in transports and communications which, allies to lower productivities, to a smaller quality and diversification of its productions, which difficult its integration in the world economy. In some SIDS these factors are not dissociating of the few investments in infrastructures, in the formation of human resources and in productive investments, just as it happens in most of the developing countries. In ecological terms, many of them with shortage of natural resources, but integrating important ecosystems in national and world terms, but with great fragility relatively to the pollution action, of excessive fishing, of uncontrolled development of tourism, factors that, conjugated and associated to the stove effect, condition the climate and the slope of the medium level of the sea water and therefore could put in cause the own survival of some of them. The drive to the awareness of the international community towards its problems summed up with the accomplishment by the United Nations in the Barbados’s Conference, 1994 where the right to the development was emphasized, through the going up the appropriate strategies and the Programme of Action for the Sustainable Development of the SIDS. The orientation of the regional and international cooperation in that sense, sharing technology (namely clean technology and control and administration environmental technology), information and creation of capacity-building, supplying means, including financial resources, creating non discriminatory and just trade rules, it would drive to the establishment of a world system economically more equal, in which the production, the consumption, the pollution levels, the demographic politics were guided towards the sustainability. It constituted an important step for the recognition for the international community on the specificities of those states and it allowed the definition of a group of norms and politics to implement at the national, regional and international level and it was important that they continued in the sense of the sustainable development. But this Conference had in its origin previous summits: the Summit of Rio de Janeiro about Environment and Development, accomplished in 1992, which left an important document - the Agenda 21, in the Conference of Stockholm at 1972 and even in the Conference of Ramsar, 1971 about “Wetlands.” CENTRO DE ESTUDOS AFRICANOS Occasional Papers © CEA - Centro de Estudos Africanos 4 Later, the Valletta Declaration, Malta, 1998, the Forum of Small States, 2002, get the international community's attention for the problems of SIDS again, in the sense that they act to increase its resilience. If the definition of “vulnerability” was the inability of the countries to resist economical, ecological and socially to the external shocks and “resilience” as the potential for them to absorb and minimize the impact of those shocks, presenting a structure that allows them to be little affected by them, a part of the available studies, dated of the 90s, indicate that the SIDS are more vulnerable than the other developing countries. The vulnerability of SIDS results from the fact the they present an assemblage of characteristics that turns them less capable of resisting or they advance strategies that allow a larger resilience to the external shocks, either anthropogenic (economical, financial, environmental) or even natural, connected with the vicissitudes of the nature. If these vulnerability factors were grouped with the expansion of the economic capitalist system at world level, the economic and financial globalisation, the incessant search of growing profits on the part of the multinational enterprises, the technological accelerated evolution drives to a situation of disfavour of the more poor. The creation of the resilience to the external shocks, to the process of globalisation, demands from SIDS and of many other developing countries the endogen definition of strategies and solid but flexible programs of integrated development. These must be assumed by the instituted power, but also by the other stakeholders, including companies and organizations of the civil society and for the population in general. But that demands strong investment in the formation of human resources, in infrastructures, in investigation centres; it demands the creation capacity not only to produce, but also to produce differently and do international marketing. It demands institutional capacity. Cape Verde is on its way to this stage.

Reverse transcription quantitative real-time polymerase chain reaction reference genes in the spared nerve injury model of neuropathic pain: validation and literature search.

BACKGROUND: The reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR) is a widely used, highly sensitive laboratory technique to rapidly and easily detect, identify and quantify gene expression. Reliable RT-qPCR data necessitates accurate normalization with validated control genes (reference genes) whose expression is constant in all studied conditions. This stability has to be demonstrated.We performed a literature search for studies using quantitative or semi-quantitative PCR in the rat spared nerve injury (SNI) model of neuropathic pain to verify whether any reference genes had previously been validated. We then analyzed the stability over time of 7 commonly used reference genes in the nervous system - specifically in the spinal cord dorsal horn and the dorsal root ganglion (DRG). These were: Actin beta (Actb), Glyceraldehyde-3-phosphate dehydrogenase (GAPDH), ribosomal proteins 18S (18S), L13a (RPL13a) and L29 (RPL29), hypoxanthine phosphoribosyltransferase 1 (HPRT1) and hydroxymethylbilane synthase (HMBS). We compared the candidate genes and established a stability ranking using the geNorm algorithm. Finally, we assessed the number of reference genes necessary for accurate normalization in this neuropathic pain model. RESULTS: We found GAPDH, HMBS, Actb, HPRT1 and 18S cited as reference genes in literature on studies using the SNI model. Only HPRT1 and 18S had been once previously demonstrated as stable in RT-qPCR arrays. All the genes tested in this study, using the geNorm algorithm, presented gene stability values (M-value) acceptable enough for them to qualify as potential reference genes in both DRG and spinal cord. Using the coefficient of variation, 18S failed the 50% cut-off with a value of 61% in the DRG. The two most stable genes in the dorsal horn were RPL29 and RPL13a; in the DRG they were HPRT1 and Actb. Using a 0.15 cut-off for pairwise variations we found that any pair of stable reference gene was sufficient for the normalization process. CONCLUSIONS: In the rat SNI model, we validated and ranked Actb, RPL29, RPL13a, HMBS, GAPDH, HPRT1 and 18S as good reference genes in the spinal cord. In the DRG, 18S did not fulfill stability criteria. The combination of any two stable reference genes was sufficient to provide an accurate normalization.

O Processo de Raciocínio na Teoria dos Constrangimentos Aplicado numa Instituição de Ensino Superior

A Teoria dos Constrangimentos (TOC) ou das Restrições tem-se mostrado uma valiosa ferramenta de gestão, auxiliando na identificação dos constrangimentos que limitem a capacidade das empresas na prossecução da sua meta. Assim, para as restrições não físicas, a TOC desenvolveu o Processo de Raciocínio que é composto por ferramentas de análise lógica que dão subsídios para o diagnóstico de problemas bem como a formulação de soluções e planos de acção para implementá-las. Neste contexto, este trabalho se propõe a determinar a adequação do Processo de Raciocínio da Teoria dos Constrangimentos numa Instituição de Ensino Superior (IES) como forma de diagnosticar os problemas e propor soluções capazes de permitir a empresa uma melhoria contínua do seu desempenho. Serão avaliadas as ferramentas que compõem o Processo de Raciocínio, que são: Árvore de Realidade Actual, Diagrama de Dispersão de nuvens, Árvore de Realidade Futura, Árvore de Pré-Requisitos e Árvore de Transição. O trabalho inicia-se com uma pesquisa bibliográfica seguida de uma pesquisa de campo e finalizando com uma aplicação do PR numa IES localizada na ilha de São Vicente. A colecta de informações para a análise processou-se mediante a aplicação de um questionário fechado aos discentes e funcionários, questionário aberto aos docentes e entrevista estruturada aos dirigentes, elaborados em coerência com os objectivos que este estudo pretende atingir. Os resultados da aplicação do método aqui apresentado permitiram chegar as conclusões apontadas no capítulo final deste trabalho The Theory of Constraints (TOC) or Restriction Theory has proved to be a valuable management tool, assisting in the identification of constraints that restrict the ability of companies in the pursuit of its goals. Therefore, for the nonphysical constraints, TOC developed the Thinking Process (TP) that consists of logical analysis tools that provide a basis for diagnosing problems and formulating solutions and action plans to implement them. This study aims, thus, to determine the suitability of the use of the Thinking Process of the Theory of Constraints in a Higher Education Institution (HEI) as a way to diagnose problems and propose solutions that enable the firm to continually improve their performance. We will evaluate the tools that make up the TP, which are: Current Reality Tree, Evaporating Cloud Diagram, Future Reality Tree, Prerequisites Tree and Transition Tree. The work starts with a literature review, followed by a field search, and finishes with an application of the reasoning process in a higher education institution, located in São Vicente. The collection of the data for the analysis was processed through the application of a closed questionnaire to students and staff, opened questionnaire to teachers and interviews to management, drafted in line with the objectives that this study aims to reach. The results of the application of the method presented here, allowed us to reach the conclusions drawn in the final chapter of this work.

Análise Económica e Financeira como Instrumento de Apoio ao Processo Decisório

O foco central deste relatório consiste em mostrar a total importância da Análise Económica e Financeira como instrumento de apoio ao processo decisório. No contexto actual onde a concorrência é cada vez mais forte e a busca pela competitividade é uma necessidade constante, as empresas necessitam de informações precisas e oportunas para apoiar o processo decisório. A escassez de recursos financeiros e o elevado custo, aliado com a falta de planeamento e controle, têm contribuído para que muitas empresas encerrem suas actividades. A tomada de boas decisões torna-se, então, um factor crucial para assegurar a sobrevivência, crescimento e permanência da empresa no mercado. Neste sentido, buscamos trazer para todos os interessados alguns conceitos e técnicas fundamentais de análise e medição da performance económica e financeira das empresas que será igualmente útil, quer a nível académica, como também a nível profissional. Procuramos evidenciar a importância de se conhecer os indicadores que podem ser vistos como alertas de possíveis falências de empresas e com base nisso, tomar decisões que determinam que estratégias utilizar para enfrentar a concorrência. A finalizar este relatório procedemos a uma pesquisa Estudo de Caso que engloba uma análise económica e financeira, baseada na análise das Demonstrações Financeiras e demais informações complementares da TRANSCOR-SV, S.A. Foram explorados alguns conceitos relacionados com o tema, mostrando de forma simples e objectiva a situação de como a empresa vem actuando no mercado. Constámos algumas deficiências, pois, foram verificados alguns pontos fracos. Diante dos problemas, sugerimos formas de mudanças e de viabilidade dos mesmos. Esperamos, então, que este relatório contribua para a empresa analisar melhor a forma de administrar a parte económica e financeira e demais sectores.The central focus of this report consists of showing to total importance of the Analysis Economic and Financial as support instrument to the ruling process. In the context actual where the competition is more and more strong and the search for the competitiveness is a constant need, the companies need necessary and opportune information to support the ruling process. The shortage of financial resources and the high cost, ally with the planning lack and control, they have been contributing so that a lot of companies contain their activities. The socket of good decisions becomes, then, a crucial factor to assure the survival, growth and permanence of the company in the market. In this sense, we looked for to bring for all the interested parties, some concepts and fundamental techniques of analysis and measurement of the performance economic and financial of the companies, which will be equally useful, he/she wants to academic level, as well as at professional level. We tried to evidence, the importance of knowing the indicators that you/they can be seen as alerts of possible bankruptcies of companies and with base in that, to make decisions that determine which strategies to use to face the competition. To conclude this report we proceeded to a research Study of Case that includes an analysis economic and financial, based on the analysis of the Financial Demonstrations and other complementary information of TRANSCOR-S.V., S.A. Some concepts related with the theme were explored, showing the situation of simple form and objective of as the company is acting in the market. It was verified some deficiencies, because, some weak points were verified. Before the problems, we suggested forms of changes and of viability of the same ones.We waited, then, which this report contributes to company to analyze the form better of administering the part economic and financial and other sectors.

The investigation of deaths in custody: a qualitative analysis of problems and prospects.

The right to be treated humanely when detained is universally recognized. Deficiencies in detention conditions and violence, however, subvert this right. When this occurs, proper medico-legal investigations are critical irrespective of the nature of death. Unfortunately, the very context of custody raises serious concerns over the effectiveness and fairness of medico-legal examinations. The aim of this manuscript is to identify and discuss the practical and ethical difficulties encountered in the medico-legal investigation following deaths in custody. Data for this manuscript come from a larger project on Death in Custody that examined the causes of deaths in custody and the conditions under which these deaths should be investigated and prevented. A total of 33 stakeholders from forensic medicine, law, prison administration or national human rights administration were interviewed. Data obtained were analyzed qualitatively. Forensic experts are an essential part of the criminal justice process as they offer evidence for subsequent indictment and eventual punishment of perpetrators. Their independence when investigating a death in custody was deemed critical and lack thereof, problematic. When experts were not independent, concerns arose in relation to conflicts of interest, biased perspectives, and low-quality forensic reports. The solutions to ensure independent forensic investigations of deaths in custody must be structural and simple: setting binding standards of practice rather than detailed procedures and relying on preexisting national practices as opposed to encouraging new practices that are unattainable for countries with limited resources.

A novel bioinformatics pipeline to discover genes related to arbuscular mycorrhizal symbiosis based on their evolutionary conservation pattern among higher plants.

BACKGROUND: Genes involved in arbuscular mycorrhizal (AM) symbiosis have been identified primarily by mutant screens, followed by identification of the mutated genes (forward genetics). In addition, a number of AM-related genes has been identified by their AM-related expression patterns, and their function has subsequently been elucidated by knock-down or knock-out approaches (reverse genetics). However, genes that are members of functionally redundant gene families, or genes that have a vital function and therefore result in lethal mutant phenotypes, are difficult to identify. If such genes are constitutively expressed and therefore escape differential expression analyses, they remain elusive. The goal of this study was to systematically search for AM-related genes with a bioinformatics strategy that is insensitive to these problems. The central element of our approach is based on the fact that many AM-related genes are conserved only among AM-competent species. RESULTS: Our approach involves genome-wide comparisons at the proteome level of AM-competent host species with non-mycorrhizal species. Using a clustering method we first established orthologous/paralogous relationships and subsequently identified protein clusters that contain members only of the AM-competent species. Proteins of these clusters were then analyzed in an extended set of 16 plant species and ranked based on their relatedness among AM-competent monocot and dicot species, relative to non-mycorrhizal species. In addition, we combined the information on the protein-coding sequence with gene expression data and with promoter analysis. As a result we present a list of yet uncharacterized proteins that show a strongly AM-related pattern of sequence conservation, indicating that the respective genes may have been under selection for a function in AM. Among the top candidates are three genes that encode a small family of similar receptor-like kinases that are related to the S-locus receptor kinases involved in sporophytic self-incompatibility. CONCLUSIONS: We present a new systematic strategy of gene discovery based on conservation of the protein-coding sequence that complements classical forward and reverse genetics. This strategy can be applied to diverse other biological phenomena if species with established genome sequences fall into distinguished groups that differ in a defined functional trait of interest.

Optimised search heuristic combining valid inequalities and tabu search

This paper presents an Optimised Search Heuristic that combines a tabu search method with the verification of violated valid inequalities. The solution delivered by the tabu search is partially destroyed by a randomised greedy procedure, and then the valid inequalities are used to guide the reconstruction of a complete solution. An application of the new method to the Job-Shop Scheduling problem is presented.

Iterated local search

Iterated Local Search has many of the desirable features of a metaheuristic: it is simple, easy to implement, robust, and highly effective. The essential idea of Iterated Local Search lies in focusing the search not on the full space of solutions but on a smaller subspace defined by the solutions that are locally optimal for a given optimization engine. The success of Iterated Local Search lies in the biased sampling of this set of local optima. How effective this approach turns out to be depends mainly on the choice of the local search, the perturbations, and the acceptance criterion. So far, in spite of its conceptual simplicity, it has lead to a number of state-of-the-art results without the use of too much problem-specific knowledge. But with further work so that the different modules are well adapted to the problem at hand, Iterated Local Search can often become a competitive or even state of the artalgorithm. The purpose of this review is both to give a detailed description of this metaheuristic and to show where it stands in terms of performance.

Solving two production scheduling problems with sequence-dependent set-up times

In today’s competitive markets, the importance of goodscheduling strategies in manufacturing companies lead to theneed of developing efficient methods to solve complexscheduling problems.In this paper, we studied two production scheduling problemswith sequence-dependent setups times. The setup times areone of the most common complications in scheduling problems,and are usually associated with cleaning operations andchanging tools and shapes in machines.The first problem considered is a single-machine schedulingwith release dates, sequence-dependent setup times anddelivery times. The performance measure is the maximumlateness.The second problem is a job-shop scheduling problem withsequence-dependent setup times where the objective is tominimize the makespan.We present several priority dispatching rules for bothproblems, followed by a study of their performance. Finally,conclusions and directions of future research are presented.
