Gestão de recursos humanos no Serviço Florestal do Nordeste

Dissertação de Mestrado, Ciências Económicas e Empresariais, 12 de setembro de 2018, Universidade dos Açores.Atualmente, para muitas organizações, os colaboradores já não são vistos como meros custos, são apontados como um dos principais fatores de vantagem competitiva da organização. Tendo em conta que os recursos humanos são agentes importantes para o sucesso de uma organização é importante também conhecer como as práticas de Gestão de Recursos Humanos (GRH) são aplicadas pelas organizações. Assim, o presente estudo teve como objetivo geral estudar as práticas de GRH numa organização, sendo que a organização escolhida foi uma entidade pública da Região Autónoma dos Açores - o Serviço Florestal do Nordeste (SFN). Para o objetivo ser alcançado optou-se pela metodologia de estudo de caso, recorrendo-se a um conjunto de técnicas de recolha de informação tais como: entrevista ao responsável dos recursos humanos e análise documental.ABSTRACT: Nowadays, for many organizations, employees are no longer seen as mere costs, they are singled out as one of the main competitive advantage factors of the organization. Given that human resources are important agents for the success of an organization, it is also important to know how Human Resources Management (HRM) practices are applied by organizations. Thus, the present study had as general objective to study the HRM practices in an organization, and the chosen organization was a public entity of the Autonomous Region of the Azores - the Forest Service of the Nordeste. In order to achieve this objective, the methodology of case study was chosen, using a set of information collection techniques such as interviewing the human resources manager and documentary analysis

Actuação de três basidiomicetas sobre a madeira de Eucalyptus globulus Labill.

Analisou-se o modo de actuação de três dos Basidiomicetos decompo- sitores da madeira do E. globulus (Coriolus versicolor, Stereum hirsutum e Daedalea quercinaj mais frequentes nas toiças provenientes da exploração daquela essência em talhadia. Tinhamos com este estudo o fim de seleccionar os fungos que poderiam vir a ser futuramente utilizados em inoculações artificiais daquela biomassa para acelerar o processo de degradação das mesmas. Pretendia-se, assim, apresentar uma alternativa à prática habitual de remoção das toiças no final da exploração. A comparação da actividade dos fungos na madeira de E. globulus (borne e cerne) foi feita através de inoculação laboratorial de provetes durante 21, 42, 63 e 84 dias e os resultados daquela actividade foram avaliados pela perda de peso dos provetes e pelas suas variações nos teores em azoto, celulose, lenhina, pentosanas e substâncias solúveis. A apreciação dos resultados obtidos permite-nos indicar o C. versicolor como o fungo mais adequado para o fim em vista, por ter sido aquele que originou maior perda de peso na madeira (borne-42% e cerne-27,5%) ao fim de 84 dias e o que se revelou capaz de despolimerizar a celulose e a lenhina no borne e no cerne. O S. hirsutum mostrou fraca actividade decompositora e esta bastante restrita ao borne. D. quercina originou um tipo de decomposição desfavorável do ponto de vista ecológico visto atacar sobretudo a celulose, com a consequente acumulação de lenhina, que é mais dificilmente degradávelinfo:eu-repo/semantics/publishedVersio

Composition of context aware mobile services using a semantic context model

Context-awareness has been regarded as an important feature for mobile services. However, only a few services are sensible to context and the features that are context-aware are still limited. Composition of Web services has received much interest in business-to-business or enterprise application, but not so much interest in business-to- consumer applications. This paper presents iCas, a novel architecture that enables the creation of context-aware services on the fly, and discusses its main components. We compare our approach with similar systems and point out the main differences and advantages. To explore context-awareness to support service composition, iCas uses SeCoM, a semantic model to represent context. The main parts of this model are explained as well the advantages of using a semantic model to represent context. We also describe the use of our approach in an university campus to provide pedagogical features and assist the socio-pedagogical interaction of various types of users

Pesquisa de microrganismos em dispensadores de antissépticos, desinfetantes e detergentes num hospital

As Infeções Associadas aos Cuidados de Saúde (IACS) estão entre as principais causas de mortalidade em todo o mundo. Adquiridas em meio hospitalar, resultam da incorreta desinfeção praticada, desde dispositivos médicos a superfícies hospitalares e práticas de higienização de profissionais de saúde. O presente trabalho teve como principais objetivos verificar a existência de microrganismos em dispensadores de antissépticos, desinfetantes e detergentes em diferentes serviços na Unidade de Saúde de Bragança; e identificar e testar o perfil de sensibilidade dos microrganismos detetados. As amostras recolhidas foram semeadas em Gelose Columbia + 5% de sangue de carneiro, incubadas a 37ºC durante 48 horas. Em caso de crescimento bacteriano procedeu- se à repicagem das colónias para meio Gelose Columbia + 5% de sangue carneiro e/ ou para meio MacConkey para obtenção de culturas puras. A identificação bacteriana e determinação do perfil de sensibilidade aos diferentes antimicrobianos foi realizada com recurso ao aparelho Vitek 2 da BioMérieux. De entre as 151 amostras semeadas, 25 apresentaram crescimento de microrganismos, constituindo uma percentagem de contaminação de 17%. Os microrganismos mais frequentemente isolados foram Staphylococcus hominis, Sphingomonas paucimobilis e Staphylococcus epidermidis com uma percentagem de 20%, 20% e 16%, respetivamente. Algumas das bactérias isoladas demonstraram perfis de resistências preocupantes que apesar de pertencerem a um grupo de bactérias comensais, estes são responsáveis por IACS. É essencial que se tomem medidas relativas ao manuseamento e acondicionamento de todas as soluções, para que se consiga diminuir a taxa de contaminação das mesmas e, consequentemente, as IACS.info:eu-repo/semantics/publishedVersio

Exploring graph topology via matrix factorization to improve Wikification

Challenges faced by authors and reviewers of encyclopedic content include the identification of which candidate concepts in one article should be linked to other articles, since concepts should be selected if they are able to provide a deeper understanding of the article topic, and ambiguity resolution. This task is called wikification. Wikification is normally addressed as a classification problem. Many supervised and semi-supervised techniques have been proposed to deal with wikification: their aim is to learn, from examples of concepts, which instances should be wikified. We observed that, although one encyclopedia can be viewed as a concept graph, supervised techniques seldom explore the richness of information provided by the graph topology: they normally only take advantage of statistical features related to concepts and the association among them. In this work, we address wikification as the problem of predicting the edges of a graph. Unlike previous approaches, our model fully explores the graph topology in the prediction task by using a matrix factorization technique. We also include in our model features related to concepts and its associations. Upon experimenting our approach with a sample of Wikipedia, we achieved gains up to 20% over a state-of-the-art baseline.CAPESCNPqFAPEA

This text presents: a running example and its context (organization of the collections in a museum); concepts of wikis as a tool to allow computer supported cooperative work (cscw); concepts of se- mantic technologies and knowledge representation; concepts and examples of semantic wikis; anatomy of a semantic wiki (reasoning tools, storage, querying); and research directions.Laboratorio de Investigación y Formación en Informática Avanzad

Filteryedping: a dwell-free eye typing technique

The ability to type using eye gaze only is extremely important for individuals with a severe motor disability. To eye type, the user currently must sequentially gaze at letters in a virtual keyboard and dwell on each desired letter for a specific amount of time to input that key. Dwell-based eye typing has two possible drawbacks: unwanted input if the dwell threshold is too short or slow typing rates if the threshold is long. We demonstrate an eye typing technique, which does not require the user to dwell on the letters that she wants to input. Our method automatically filters out unwanted letters from the sequence of letters gazed at while typing a word. It ranks candidate words based on their length and frequency and presents them to the user for confirmation. Spell correction and support for typing words not in the corpus are also included.São Paulo Research Foundation (FAPESP) (grant #2012/01510-0)CAPESCNP

Mobile video annotations: a case study on supporting rehabilitation exercises

Annotations enable us to highlight key points or add information to content presented, for instance, on paper or digital media. Even though smartphones and tablets facilitate video capturing, currently only few applications allow limited video annotations using the mobile device itself. Given that video annotations can assist many tasks that depend or can be enhanced by video capturing, in previous work we have contributed with a tool for allowing multimodal video annotation using mobile devices. Upon experimenting with the tool, we identified that reviewing rehabilitation exercise videos can be especially enhanced with video annotations. Professionals in the field of physiotherapy and occupational therapy can add relevant annotations for their patients to improve performance of their exercises. After an evaluation with a specialist in occupational therapy, we identified new requirements associated with the monitoring of patients. We then identified the opportunity to develop a monitoring system with the collaboration of two rehabilitation specialists. Since these two specialists work with mirror therapy, we defined requirements that are relevant for this type of therapy. The system was developed to support the monitoring of exercises combined with video recording and annotation capabilities. The system aims to support rehabilitation therapy by distance: therapists can monitor patients as they record videos that are sent for evaluation. We identified requirements that may be applied in many scenarios, however mirror therapy demanded many specific requirements related to the recording of videos.Coordination for the Improvement of Higher Education Personnel (CAPES)São Paulo Research Foundation (FAPESP, grant #2011/17040-0)National Council for Scientific and Technological Development (CNPq

Use of smartphones by older adults: characteristics and reports of students enrolled at a University of the Third Age (U3A)

Introduction: The increase in mobile device users aged > 60 years reflects a transformation in the information and communication technology (ICT) area. Supporting older adults in their digital literacy is a complex task. New skills for the digital age should be developed. Objective: To describe the sociodemographic characteristics of older adults on a digital literacy program, including patterns of use, reasons for learning, in addition to the difficulties and benefits reported regarding the use of technology. Methodology: A quantitative and qualitative study based on a digital literacy program within a U3A context involving professionals in the fields of gerontology and computing was conducted. Result: The program involved 317 older adults, most of whom were women (64.5%). Mean age of participants was 60-74 years (82%). Regarding characteristics, 44.2% were married, 40.7% had finished high school, 77.3% were retired, 65.1% earned ≤ 4 minimum wages, and 74.1% were not engaged in paid employment. Prior to participation, despite the high frequency of smartphone use (87.6%), 77.9% reported having a poor user experience. The most prevalent purposes for using smartphones were “Communication” (93.3%), “Strengthening affectional bonds with family and friends” (66.2%) and “Search for general information” (48.7%). The assessment of self-efficacy revealed that participants lacked competence for complex activities. Conclusion: The interest of older Brazilians in using smartphones is clear. Therefore, understanding previous competencies, as well as the obstacles faced by this group, is pivotal in aiding the process of digital inclusion.Introduction: The increase in mobile device users aged > 60 years reflects a transformation in the information and communication technology (ICT) area.
