Avaliação da performance do árbitro de futebol 11 : estudo de caso

O aumento da carga física do jogo de futebol provocou uma maior exigência e desenvolvimento na condição física dos jogadores e por inerência, nos árbitros. Assim o presente estudo procurou identificar e desenvolver um teste para a avaliação dos árbitros de futebol. Foi realizada uma análise sistemática para identificação e descrição da produção científica na área da arbitragem no sentido de sustentar o argumento de insuficiência dos testes vigentes e propor o novo teste que denominámos ETSOR. Após esta, foi realizada uma aplicação piloto com recurso ao método de estudo de caso para testagem do ETSOR. Os resultados revelaram que existe uma dispersão nas formas e conteúdos abordados face à caracterização do árbitro de futebol de 11. A partir do método de meta-análise, é apresentada uma proposta de categorização dos conteúdos. Os resultados revelaram também que o teste FIFA não identifica as intensidades irregulares que decorrem das situações do jogo, nem representa a uma distribuição das intensidades dos esforços dos árbitros nas situações de jogo. O Teste ETSOR, como teste ecológico, capta em termos de densidade, de distribuição, de variação da potência e de resistência, os esforços dos árbitros nas situações de jogo, como testa a características das intensidades máximas da atividade do árbitro. Por último, os resultados reforçaram que este processo que se deve estender de forma periodizada ao longo de cada época tornando-se útil, na medida em que permite a otimização e monitorização da prestação do árbitro.

Visitabilidade-vivenciabilidade em assentamentos informais : um estudo da acessibilidade de percursos urbanos no Conjunto Santa Terezinha em Fortaleza-CE

This research approaches the issue of accessibility in informal settlements, seeking for the challenges and limits defined by informal urban settings, about the application of accessibility parameters. Take the empirical universe as the Conjunto Santa Terezinha, located in Fortaleza- Ce. Initially, the study presents a reflection about the housing issue in Brazil and the informal settlementes in view of the Right to the City. In this sense, the main references are, the works of Suzanne Pasternak (2008), Nabil Bonduki (1998) and Erminia Maricato (1996-97), among others. Follows with the discussion of the concepts and classifications of this type of settlement, making a content analysis of legislation and regulations relating to accessibility and proposed the discussion of the accessible route as the right strategy for the city. In another step, the methodology of 'walking together' created by Dischinger (2000) was applied in a passage previously chosen, which the researcher follows the disabled person during the journey through city making records like photos and video. The comments and perceptions are compared to the spatial analysis of urban morphology, made from the method of Del Rio (1990) and Panerai (2006), and the parameters of NBR 9050. Knowledge of the area is enriched by the methodology of the production of space made by Henri Lefebvre in his book 'The production of space' (1974) with these categories: space conceived, perceived and lived. Another key reference of this author it s the book 'The Right to the City' (991), which allowed in-depth reflections on the social function of town. In conclusion, the study finds that to guarantee a minimum access conditions in informal sittlements it´s necessary to know the specifics of their morphology, their relations and urban practices in view of the visitability- experiencebility, describing it as complementary concepts

Intervention for organizational innovation: a case study

This article is intended to report an intervention in a SME of the IT sector, aiming at an organizational change process towards a greater proactivity of employees. The presentation of the case includes the diagnosis, intervention, and the beginning of the implementation of innovation projects, based on an adapted model of third generation large-group organizational change methods. In addition to the steps followed, small-world analysis techniques were used, with the intention of determining the existing communication networks; also, a content analysis of collected success stories was made, in order to suggest strong points for a future organizational culture. The results clarified the desirable characteristics of an intervention method with large groups, adapted to Portuguese companies, and effective in organizational innovation project design. The analysis of the success stories helped to determine the strengths of an orientation for the future, while the use of measures of small-world networks allowed us to analyze the existing informal organization. Although this study does not include the completion of the projects, due to difficulties in the company, it can provide a solid basis for application in future interventions.

O gigantesco passo da artilharia de campanha de 1914 para 1918

O presente trabalho de investigação tem como objetivo geral investigar os grandes progressos e inovações da Artilharia de Campanha no decorrer da Primeira Guerra Mundial. O período analisado está inserido no conflito da Primeira Guerra Mundial de 1914-1918, que se caracterizou fundamentalmente por ser um conflito onde existiu pouca mobilidade, uma quantidade excessiva de mortes e um desenvolvimento progressivo de armamento pesado para fazer face ao impasse provocado por uma guerra essencialmente de trincheiras. O crescimento exponencial da artilharia tornou-se, então, uma urgente necessidade num conflito onde a inovação dos materiais se sobrepôs à quantidade de homens. Para a elaboração deste trabalho de investigação aplicada, tendo como modelo o método da investigação histórica, foi analisada, numa abordagem diacrónica, o desenvolvimento da materiais e doutrinas utilizados pelas unidades de artilharia, sendo destacados essencialmente os exércitos da Alemanha, França e Grã-Bretanha. Por outro lado, numa abordagem sincrónica, foram identificadas as distintas inovações tais como o nascimento de novos tipos de artilharia, grande diversificação nas munições, tendência para a artilharia de tiro indireto substituir a de tiro direto, desenvolvimentos no controlo do tiro, novas formas de comunicação, artilharia de muito maior alcance, entre outros, pelo que este trabalho tem como finalidade demonstrar o papel da artilharia na criação do sistema de trincheiras e posteriormente no ultrapassar da imobilidade destas. Este trabalho baseia-se na análise de conteúdo de fontes primárias manuscritas e impressas, textuais e iconográficas, nacionais e internacionais, diretamente relacionadas com o tema abordado.

DNA extraction and RAPD markers to assess the genetic similarity among Gelidium sesquipedale (Rhodophyta) populations

A simple method developed for genomic DNA isolation from fungus was tested on the red alga, Gelidium sesquipedale (Clem.) Born et Thur., which is commercially exploited for its high sulfated polysaccharide (agar) content. This method is faster, cheaper, and less toxic than conventional phenol/chloroform methods. Random amplified polymorphic DNA (RAPD) amplifications were performed successfully without the necessity of purifying the DNA. RAPD markers were used to investigate the genetic similarity among three natural populations of G. sesquipedale from southern Portugal. Bulked-genomic DNA samples of 15 different individuals were made in each population. These can be conceived of as a sample of the population DNA. Of the 62 primers screened, 41 produced bands and 22 revealed polymorphisms. Genetic similarities among populations were high. Populations that are further away from each other have the lowest similarity coefficients, whereas the intermediate Ingrina population, located on the south coast, showed higher genetic similarity with the Odeceixe population located on the southwest coast, than with the Sao Rafael southern population. This suggests a higher genetic flow between Odeceixe and Ingrina or the result may be a founder effect in the sense that the species has propagated from the east coast to the south coast of Portugal. We conclude that the use of this isolation method with RAPD analysis is appropriate to characterize the genetic variability of this commercial species along its geographical distribution. Large sample sizes can be screened at a relatively low cost. Finding genetic markers for commercial populations of C. sesquipedale may be of industrial interest.

The conversation on political issues on Twitter: an analysis of the participation and frames in the debate on the 'Wert law' and evictions in Spain

The aim of this study is to determine which social agents are involved in the political debate on Twitter and whether the interpretive hegemony of actors that have traditionally been the most prominent is tempered by the challenge of framing shared with audiences. The relationship between the interpretations expressed and the profiles of participants is analyzed in comparison with the frames used by mainstream media. The chosen methodology combines content analysis and discourse analysis techniques on a sample of 1,504 relevant tweets posted on two political issues –the approval of the education law LOMCE and the evictions caused by the crisis, which have also been studied in the front pages of four leading newspapers in Spain. The results show a correlation between political issue singularities, frames and the type of discussion depending on the participants.

Inter-industry analysis and monetary policy evaluations in the Korean flow of funds accounts

This study mainly aims to provide an inter-industry analysis through the subdivision of various industries in flow of funds (FOF) accounts. Combined with the Financial Statement Analysis data from 2004 and 2005, the Korean FOF accounts are reconstructed to form "from-whom-to-whom" basis FOF tables, which are composed of 115 institutional sectors and correspond to tables and techniques of input–output (I–O) analysis. First, power of dispersion indices are obtained by applying the I–O analysis method. Most service and IT industries, construction, and light industries in manufacturing are included in the first quadrant group, whereas heavy and chemical industries are placed in the fourth quadrant since their power indices in the asset-oriented system are comparatively smaller than those of other institutional sectors. Second, investments and savings, which are induced by the central bank, are calculated for monetary policy evaluations. Industries are bifurcated into two groups to compare their features. The first group refers to industries whose power of dispersion in the asset-oriented system is greater than 1, whereas the second group indicates that their index is less than 1. We found that the net induced investments (NII)–total liabilities ratios of the first group show levels half those of the second group since the former's induced savings are obviously greater than the latter.

Exploring Hidden Coherent Feature Groups and Temporal Semantics for Multimedia Big Data Analysis

Thanks to the advanced technologies and social networks that allow the data to be widely shared among the Internet, there is an explosion of pervasive multimedia data, generating high demands of multimedia services and applications in various areas for people to easily access and manage multimedia data. Towards such demands, multimedia big data analysis has become an emerging hot topic in both industry and academia, which ranges from basic infrastructure, management, search, and mining to security, privacy, and applications. Within the scope of this dissertation, a multimedia big data analysis framework is proposed for semantic information management and retrieval with a focus on rare event detection in videos. The proposed framework is able to explore hidden semantic feature groups in multimedia data and incorporate temporal semantics, especially for video event detection. First, a hierarchical semantic data representation is presented to alleviate the semantic gap issue, and the Hidden Coherent Feature Group (HCFG) analysis method is proposed to capture the correlation between features and separate the original feature set into semantic groups, seamlessly integrating multimedia data in multiple modalities. Next, an Importance Factor based Temporal Multiple Correspondence Analysis (i.e., IF-TMCA) approach is presented for effective event detection. Specifically, the HCFG algorithm is integrated with the Hierarchical Information Gain Analysis (HIGA) method to generate the Importance Factor (IF) for producing the initial detection results. Then, the TMCA algorithm is proposed to efficiently incorporate temporal semantics for re-ranking and improving the final performance. At last, a sampling-based ensemble learning mechanism is applied to further accommodate the imbalanced datasets. In addition to the multimedia semantic representation and class imbalance problems, lack of organization is another critical issue for multimedia big data analysis. In this framework, an affinity propagation-based summarization method is also proposed to transform the unorganized data into a better structure with clean and well-organized information. The whole framework has been thoroughly evaluated across multiple domains, such as soccer goal event detection and disaster information management.

Violência conjugal percebida por um menor em contexto familiar e suas consequências psicossociais

A violência como fenómeno social e familiar, não é um problema atual, desde sempre esteve presente, sendo que a sua exposição apresenta diferentes intensidades em diferentes momentos da sua evolução. Como fenómeno mundial, percorreu todas as culturas, etnias, tipos de economia e regimes políticos (Sagim, 2003). O objectivo da presente investigação é a violência conjugal percebida por um menor em contexto familiar e suas consequências psicossociais: estudo de caso. Método: A metodologia escolhida é qualitativa e é designada por naturalista. O método utilizado foi o estudo de caso e a recolha de dados foi a entrevista (semi-estruturada) e fez-se a descodificação desta através da análise de conteúdo, que foi organizada em várias categorias . Instrumentos: Questionário sócio demográficos (filha); Guião de Entrevista para adultos(mãe), semi-estruturada; Entrevista Clínica Semi–Estruturada (SCICA);A Escala de Sinalização do Ambiente Natural Infantil (S.A.N.I.); O teste projectivo Pata Negra de Corman (filha). Participantes: R de 12 anos de idade, sexo feminino, caucasiana, possui o 9º ano de escolaridade Resultados: Verificou-se que R tem uma boa capacidade de coping e resolução de problemas, indo do encontro referido por alguns autores nos meus estudos, sendo que noutros não se enquadra no perfil defendido pela literatura. Referindo segundo o DSM-5, R apresenta alguma sintomatologia clínica como a ansiedade de separação, revelando insegurança e medo da perda dos afetos por parte dos progenitores. Conclusão: : Concluiu-se ainda que alguns estudos referem que nem todas as crianças expostas à violência intrafamiliar responderão negativamente, uma vez que a presença de fatores de proteção tèm um papel fundamental. Entre estes, o ambiente escolar, o relacionamento com a vizinhança e o suporte advindo de demais membros familiares, entre outros (Sani, 2008).

Hälsoundersökning av asylsökande personer - ur ett distriktssköterskeperspektiv : En kvalitativ intervjustudie

The Swedish health care system has in recent years been faced with a challenge in relation to the increased inflow of refugees. Under Swedish law, asylum seekers should be provided the opportunity to receive health screening to determine the risk of infection and the possible need for care, as well as information about the Swedish health care to be provided. The health screening is conducted by district nurses and nurses. The purpose of this study was to investigate the nurses' experience of conducting health screening of asylum seekers. A qualitative study with semi-structured interviews was used as method of data collection. A total of eleven interviews were conducted with district nurses in two counties, in eight cities. Data from the interviews were analyzed using qualitative content analysis. This resulted in three main themes, Health screening characteristics vary, Cultural differences affect the meeting and Challenging for the district nurse. The results showed that the district nurses' organization of and the approach to the health screenings differ.  The mental health of asylum seekers is seen by district nurses in a high degree and this is experienced problems with the care. Intercultural competence and improved communications capabilities were key elements associated with health screening of asylum seekers. The term 'health care that cannot be postponed "was considered difficult to assess and there is a risk that asylum seekers receive incongruent treatment.

Factors influencing the use of evidence based practice among physiotherapists and occupational therapists in their clinical work

Background: Evidence-based practice (EBP) is a process through which research is applied in daily clinical practice. Occupational therapists (OTs) and physiotherapists (PTs) are expected to work in line with EBP in order to optimise health care resources. This expectation is too seldom fulfilled. Consequently, research findings may not be implemented in clinical practice in a timely manner, or at all. To remedy this situation, additional knowledge is needed regarding what factors influence the process of EBP among practitioners. The purpose of the present study was to identify factors that influence the use of EBP and the experienced effects of the use of EBP among PTs and OTs in their clinical work. Method: This was a qualitative interview study that consisted of six group interviews involving either OTs or PTs employed by the Jönköping County Council in the South of Sweden. Resulting data were analysed using content analysis. Results: The analysis resulted in the following categories: “definition of evidence and EBP”, “sources of evidence”, “barriers to acquiring evidence and to using evidence in clinical work”, “factors that facilitate the acquisition of evidence and the use of evidence in clinical work”, and “personal experiences of using EBP”. Basing clinical practice on scientific evidence evoked positive experiences, although an ambivalent view towards acting on clinical experience was evident. Participants reported that time for and increased knowledge about searching for, evaluating, and implementing EBP were needed. Conclusion: Because OTs are more oriented towards professional theories and models, and PTs are more focused on randomised controlled trials of interventions, different strategies appear to be needed to increase EBP in these two professions. Management support was considered vital to the implementation of EBP. However, the personal obligation to work in line with EBP must also be emphasised; the participants apparently underestimate its importance.

Retaining formal volunteers in volunteer based organizations

Abstract Problem Formal Volunteers in volunteer based organizations drop out at a fast pace due to many reasons like lack of interest what they are doing, conflict among volunteers, lack of motivation, job dissatisfaction due to prolonged volunteering etc.  which is causing to improper functioning of these organizations and reaches a point where these volunteer based organizations find it difficult to function properly. The author in this study tries to address this particular issue of this drop out of formal volunteers. Purpose The purpose of this study is to explore the factors which helps in the retention of formal volunteers in a volunteer based organization for a longer period. Method The research in this paper is done in a qualitative way with primary data collected in the form of participant observation and open interview in two voluntary organizations. The collected data is analyzed in content analysis. The secondary data is collected in the form of necessary documents provided by the participating organizations. Results Many factors were found to influence retention of volunteers namely Job satisfaction, Motivation, Public Service Motivation, Organizational Commitment, Mission Attachment, Work load, Relationship with Coworkers, Justice of Organization, Flexible Timing, Training & Orientation.  Conclusions Recommendations to improve retention is mentioned and a future model is also proposed. The result obtained from this research can be generalized to other form of small scale volunteer organizations where the major employees are formal volunteers.
