Este trabajo de investigación es pionero y original ya que nunca antes se ha realizado un estudio de la gineta (Genetta genetta) dentro del ámbito valenciano y más concretamente sobre la relación de su distribución con los factores geográficos que la condicionan en el PN Sierra de Mariola. Un mejor conocimiento de su ocupación en el espacio será de interés para la definición de medidas de gestión de fauna del Parque. Utilizando técnicas de fototrampeo se han recopilado 95.372 imágenes con algún contacto animal. De estas imágenes, el 0,10% de las fotografías registradas son de gineta y se ha detectado su presencia en 8 de las 63 cuadrículas (4 Km2) del PN Sierra de Mariola (12,70%). Este estudio ha permitido integrar la información recopilada en campo con las bases de datos existentes para concluir que la situación de la gineta en Sierra de Mariola no es preocupante.

A crioterapia é prática comum na medicina esportiva, pela praticidade, facilidade de acesso e baixo custo, possuindo vantajoso uso na Saúde Pública. No entanto, os efeitos analgésicos do gelo tem pouca base objetiva e sistematizada em termos de técnicas, duração e frequência. O objetivo deste estudo foi sintetizar através da revisão sistemática (RS) as evidências relativas à efetividade da crioterapia para o tratamento das entorses de tornozelo de atletas. A RS é um método de pesquisa observacional e retrospectivo, pelo qual se tratam artigos, preferencialmente Ensaios Clínicos Aleatórios – ECA, como sujeitos da investigação, com rigorosos critérios de inclusão e exclusão e, quando possível, realiza-se uma macro estatística dos resultados – metaanálise. No presente RS, foram consultados cinco bancos de dados - Medline, Embase, Cochrane, Lilacs e PEDro para buscar ECA sobre crioterapia com os desfechos dor, edema, rigidez e função. Resultados: 289 estudos foram identificados inicialmente, dos quais nove com tratamentos isolados ou associados à crioterapia, porém apenas um preencheu aos critérios de inclusão, cujo N era 121 atletas, dos quais 64 receberam a crioterapia (funcional) e 57 no grupo controle (imobilização). Maior probabilidade para o evento dor foi observada no grupo controle, após 3 e 12 meses. A RS revelou uma lacuna em ECA dentro do tema, mas não encontrou efeito adverso na prática da crioterapia, sendo um princípio analgésico importante, sobretudo em lesões de tecidos moles.

Enquadramento: A parentalidade é um tema de saúde com muita relevância na sociedade atual, intervindo o seu exercício na promoção da saúde e bem-estar da criança. A parentalidade envolve acontecimentos stressantes, nomeadamente em situações de problemas de saúde e necessidades básicas e de resposta ao comportamento da criança, como é o caso do choro/birra e no momento de alimentação, procurando a maioria dos cuidadores responder ao problema de forma independente enquanto outros solicitam apoio dos profissionais de saúde. Objetivo: Identificar recomendações concretas, baseadas na evidência científica, de boas práticas e recomendações a transmitir aos pais para lidarem com o choro /birras e no momento da alimentação da criança. Métodos: Realizou-se uma revisão sistemática da literatura de estudos realizados nos idiomas português, inglês e espanhol, publicados entre 2009 e 2014, em bases de dados internacionais CINAHL® Plus with Full-Text, Nursing & Allied Health Collection, Cochrane Central Register of Controlled Trials; Cochrane Database of Systematic Reviews (CDSR) e Database of Abstracts of Reviews of Effects (DARE), MedicLatina , MEDLINE, com recurso a diversos descritores e operadores booleanos e recorrendo a dois revisores que avaliaram a qualidade dos estudos metodológicos. Resultados: Após avaliação crítica, foram excluídos 50 estudos e incluídos 7, sendo um de grau de evidência A, dois de evidência B e 4 de evidência D. Os outcomes evidenciaram que para gestão da parentalidade o aconselhamento deve feito pelo profissional de referência, que se necessário deverá acompanhar os pais através de contacto telefónico e visita domiciliária sobretudo se mães inexperientes. Os profissionais devem ampliar os seus conhecimentos sobre as dúvidas e preocupações que os pais têm sobre a educação dos seus filhos consultando os espaços de discussão online. A etnia e nacionalidade das mães tem forte impacto sobre os métodos usados para acalmar o bebé, pelo que os cuidados devem ser culturalmente congruentes. Na abordagem do choro/ birras torna-se necessário conhecer o normal desenvolvimento da criança e em que contextos surgem para minimizá-las, sendo importante que os pais dêem à criança atenção positiva, instituindo rotinas. Para melhorar o momento da alimentação os pais devem reconhecer que até aos dois anos decorre a janela de oportunidade de aprendizagem de rotinas e de novos sabores, salientando-se a importância do ambiente de atenção e reciprocidade durante as refeições. Conclusão: Os enfermeiros devem procurar orientar a sua prática com base nas evidências científicas e tendo como base o estudo efectuado, salienta-se a promoção da parentalidade positiva como central para a abordagem dos comportamentos de choro/birra e no momento da alimentação da criança. Palavras – chaves: educação parental, enfermeiro, aleitamento materno, alimentação, birra, choro, relação pais-filhos.

This doctoral thesis originates from an observational incongruence between the perennial aims and aspirations of economic endeavour and actually recorded outcomes, which frequently seem contrary to those intended and of a recurrent, cyclical type. The research hypothesizes parallel movement between unstable business environments through time, as expressed by periodically fluctuating levels of economic activity, and the precipitation rates of industrial production companies. A major problem arose from the need to provide theoretical and empirical cohesion from the conflicting, partial and fragmented interpretations of several hundred historians and economists, without which the research question would remain unanswerable. An attempt to discover a master cycle, or superimposition theorem, failed, but was replaced by minute analysis of both the concept of cycles and their underlying data-bases. A novel technique of congregational analysis emerged, resulting in an integrated matrix of numerical history. Two centuries of industrial revolution history in England and Wales was then explored and recomposed for the first time in a single account of change, thereby providing a factual basis for the matrix. The accompanying history of the Birmingham area provided the context of research into the failure rates and longevities of firms in the city's staple metal industries. Sample specific results are obtained for company longevities in the Birmingham area. Some novel presentational forms are deployed for results of a postal questionnaire to surviving firms. Practical demonstration of the new index of national economic activity (INEA) in relation to company insolvencies leads to conclusions and suggestions for further applications of research into the tempo of change, substantial Appendices support the thesis and provide a compendium of information covering immediately contiguous domains.

This paper describes the knowledge elicitation and knowledge representation aspects of a system being developed to help with the design and maintenance of relational data bases. The size algorithmic components. In addition, the domain contains multiple experts, but any given expert's knowledge of this large domain is only partial. The paper discusses the methods and techniques used for knowledge elicitation, which was based on a "broad and shallow" approach at first, moving to a "narrow and deep" one later, and describes the models used for knowledge representation, which were based on a layered "generic and variants" approach. © 1995.

The aim of this work was to develop a new methodology, which can be used to design new refrigerants that are better than the currently used refrigerants. The methodology draws some parallels with the general approach of computer aided molecular design. However, the mathematical way of representing the molecular structure of an organic compound and the use of meta models during the optimization process make it different. In essence, this approach aimed to generate molecules that conform to various property requirements that are known and specified a priori. A modified way of mathematically representing the molecular structure of an organic compound having up to four carbon atoms, along with atoms of other elements such as hydrogen, oxygen, fluorine, chlorine and bromine, was developed. The normal boiling temperature, enthalpy of vaporization, vapor pressure, tropospheric lifetime and biodegradability of 295 different organic compounds, were collected from open literature and data bases or estimated. Surrogate models linking the previously mentioned quantities with the molecular structure were developed. Constraints ensuring the generation of structurally feasible molecules were formulated and used in commercially available optimization algorithms to generate molecular structures of promising new refrigerants. This study was intended to serve as a proof-of-concept of designing refrigerants using the newly developed methodology.

The Brazilian CAPES Journal Portal aims to provide Information in Science and Technology (IST) for academic users. Thus, it is considered a relevant instrument for post-graduation dynamics and the country´s Science and Technology (S&T) development. Despite its importance, there are still few studies that focus on the policy analysis and efficiency of these resources. This research aims to fill in this gap once it proposes an analysis of the use of the CAPES Journal Portal done on behalf of the master´s and doctoral alumni of the Post Graduate Program in Management (PPGA) at the Federal University of Rio Grande do Norte (UFRN). The operationalization of the research´s main objective was possible through the specific objectives: characterize graduate profile as CAPES Journal Portal users b) identify motivation for the use of CAPES Journal Portal c) detect graduate satisfaction degree in information seeking done at CAPES Journal Portal d) verify graduate satisfaction regarding the use of the CAPES Journal Portal e) verify the use of the information that is obtained by graduates in the development of their academic activities. The research is of descriptive nature employing a mixed methodological strategy in which quantitative approach predominates. Data collection was done through a web survey questionnaire. Quantitative data analysis was made possible through the use of a statistical method. As for qualitative analysis, there was use of the Brenda Dervin´s sense-making approach as well as content analysis in open ended questions. The research samples were composed by 90 graduate students who had defended their dissertation/thesis in the PPGA program at UFRN in the time span of 2010-2013. This represented by 88% of this population. As for user profile, the analysis has made evident that there are no quantitative differences related to gender. There is predominance of male graduates that were aged 26 to 30 years old. As for female graduates, the great majority were 31 o 35 years old. Most graduates had Master´s degree scholarship in order to support their study. It was also seen that the great majority claim to use the Portal during their post graduation studies. The main reasons responsible for non use was: preference for the use of other data bases and lack of knowledge regarding the Portal. It was observed that the most used information resources were theses and dissertations. Data also indicate preference for complete text. Those who have used the Portal also claimed to have used other electronic information fonts in order to fulfill their information needs. The information fonts that were researched outside in the Portal were monographs, dissertations and thesis. Scielo was the most used information font. Results reveal that access and use of the Portal has been done in a regular manner during post graduation studies. But on the other hand, graduates also make use of other electronic information fonts in order to meet their information needs. The study also confirmed the important mission performed by the Portal regarding Brazilian scientific communication production. This was seen even though users have reported the need for improvement in some aspects such as: periodic training in order to promote, encourage and teach more effective use of the portal; investment aiming the expansion of Social Sciences Collection in the Portal as well as the need to implement continuous evaluation process related to user satisfaction in regarding the services provided.

Purpose- Entrepreneurship education (EEd) plays a crucial role in the development of entrepreneurs and the enhancement of entrepreneurial activities in every economy. This paper examined what Higher education Institutions (HEIs) do in learning and teaching of entrepreneurship in general and how entrepreneurship development takes place in Nigerian HEIs. The outcome from this study will enable a deeper understanding on what HEIs do EEd, with more exposure as to what the areas and focus of research is in the Nigerian context. Design/methodology/approach- The study adopted a systematic literature review approach- drawing from a computerized search of five selected data bases, using predetermined key words by the researchers. Findings: The main finding of this paper is that, related concepts like skills, intention, drive and attitude have been use in expounding discussions on the outcome of EEd, but very little has been written on entrepreneurial mind-set (EMS), of which other studies have suggested that it’s a crucial point in the journey of an entrepreneurs (Reed & Stoltz, 2011; Quality Assurance Agency for Higher Education (QAA), 2012; Neneh, 2012). Furthermore, learning and teaching of entrepreneurship in Nigerian HEIs seems to be more on creating awareness (about entrepreneurship) than actual preparation for entrepreneurship (For entrepreneurship). Research limitations/implications- The paper is limited since it is based on a review of literature from a selected databases- covering a specific time span. This potentially excludes other studies outside this time span. A more comprehensive overview of these contributions would benefit from employing tools such as Google Scholar, for an overview of the sub–domains online. Originality/value – There are limited studies that focus on the issue of entrepreneurial mind-set in entrepreneurship education in Africa, specifically Nigeria. This paper and its focus in particular, have laid down pioneering ground work for research on entrepreneurial mind-set development in Nigerian entrepreneurship education.

Bakgrund: Psykisk ohälsa ökar i hela världen, även i Sverige, främst hos den unga, kvinnliga befolkningen. Psykiska problem är ofta kopplade till somatisk ohälsa. Kvaliteten på den somatiska vården blir ofta sämre, mycket på grund av att många sjuksköterskor inte har tillräckligt med kunskap och erfarenhet inom psykiatriska omvårdnaden. Syfte: Föreliggande arbete avser att undersöka sjuksköterskors attityder och erfarenheter av patienter med psykisk ohälsa inom den somatiska vården. Metod: Litteraturöversikt av vetenskapliga artiklar. Litteratursökning i databaser med hjälp av lämpliga sökord. Artiklarnas kvalitet granskas sedan med hjälp av granskningsmallar. Resultat: Sammanlagt granskades 15 artiklar, varav 8 kvalitativa och 7 kvantitativa. Undersökningen visar att sjuksköterskor ofta har negativa erfarenheter av att vårda patienter med psykisk ohälsa. En förklaring kan vara bristande kunskap och färdigheter, vilket leder till rädsla, frustration och stress i mötet med dessa patienter. Även miljön nämns som som en stress- och orsaksfaktor till detta. Dessa faktorer leder till att sjuksköterskor till övervägande del har negativa attityder mot denna patientgrupp. Slutsats: Slutsatsen av undersökningen visar att de identifierade bristerna när det gäller kunskap och färdigheter bland annat leder till otrygghet vid vård av patienter med psykisk ohälsa inom den somatiska vården. Förbättring av detta tillstånd kan uppnås genom att höja sjuksköterskors kompetens, t.ex. genom att lägga större vikt på den psykiatriska omvårdnaden inom den praktiska utbildningen.
