Estudio sobre la construcción autorregulada del portafolio en el grado de Enfermería

Introduction. This study presents the results of the implementation process of portfolio in the course of four consecutive years. The plan includes three phases (initiation, development and consolidation). The sample is 480 students studying the first year of nursing at the University of Girona. The objective is to evaluate the effectiveness of the instrument and achieve its construction in a self-regulated process. Subjects and methods. The proposed methodology is based on the sequential triangulation between methods. The study of the same empirical unit it’s used two investigation strategies, quantitative and qualitative. Study 1: quantitative, descriptive, longitudinal and prospective. The statistical analysis of paired data for continuous variables that follow a normaldistribution is made with t Student-Fisher test. The correlation between two numerical variables is used the Pearson correlation index. Study 2: qualitative, uses the discussion groups and topics. For textual data analysis is used Atlas.ti. Results. The final score for students who prepare the portfolio is higher (7.78) than the score who do not prepare (7) (p ≤ 0.001). A significant correlation exists between the portfolio score and final score (p ≤ 0.001). The trend study showsa greater sensitivity of the instrument assessment. Conclusion. The final design of the portfolio is characterized by mixed, flexible and encourages the student reflection and empowers the reflection on the continuum of learning

Designing flexible procurement systems

The systems used for the procurement of buildings are organizational systems. They involve people in a series of strategic decisions, and a pattern of roles, responsibilities and relationships that combine to form the organizational structure of the project. To ensure effectiveness of the building team, this organizational structure needs to be contingent upon the environment within which the construction project takes place. In addition, a changing environment means that the organizational structure within a project needs to be responsive, and dynamic. These needs are often not satisfied in the construction industry, due to the lack of analytical tools with which to analyse the environment and to design appropriate temporary organizations. This paper presents two techniques. First is the technique of "Environmental Complexity Analysis", which identifies the key variables in the environment of the construction project. These are classified as Financial, Legal, Technological, Aesthetic and Policy. It is proposed that their identification will set the parameters within which the project has to be managed. This provides a basis for the project managers to define the relevant set of decision points that will be required for the project. The Environmental Complexity Analysis also identifies the project's requirements for control systems concerning Budget, Contractual, Functional, Quality and Time control. The process of environmental scanning needs to be done at regular points during the procurement process to ensure that the organizational structure is adaptive to the changing environment. The second technique introduced is the technique of "3R analysis", being a graphical technique for describing and modelling Roles, Responsibilities and Relationships. A list of steps is introduced that explains the procedure recommended for setting up a flexible organizational structure that is responsive to the environment of the project. This is by contrast with the current trend towards predetermined procurement paths that may not always be in the best interests of the client.

Vocational English in policy and practice

The aim of this licentiate thesis is to examine how, and in what ways, vocational English is a part of English language teaching in the Building and Construc­tion Programme in Sweden, and what the influences are for such pedagogy. The main research question is how policy documents relate to the views of teachers and their educational practice regarding vocational English. The study consists of two parts: a textual policy analysis of the three latest upper secondary school reforms in Sweden (Lgy 70, Lpf 94, and Gy 2011), and semi-structured interviews with practicing English teachers in the Building and Construction Programme. The interviews are categorised by using Spradley’s (1979) semantic relationships and taxonomies. Balls’ (Ball, 1993) and Ozga’s (1990; 2000) concept of policy enactment is used in the analysis as well as Bernstein’s (1990; 2000) theoretical framework of classification, framing, and horizontal and vertical discourse. The results show that five of the six teachers in the interviews work with vocational English in some way. The study also shows that there is a distinct gap between policy and practice. Several of the teachers have the notion that they are supposed to work with vocational English and that it must be written down in policy somewhere. The greatest influence on the teaching for these teachers are their students, either indirectly or directly. Further, the study shows that different frame factors such as time poverty hinders the teachers from reading policy texts and cooperating with the vocational teachers in the Building and Construction Programme.

Ações educativas com portadores de diabetes Mellitus através da educação popular em saúde

Popular Health Education in its emancipatory dimension refers to individuals and groups to exchange knowledge and experiences, allowing them to associate health to the outcomes of their living conditions. Under this view, health workers and health users are subjects of the educative process. Thus, this study aims to identify the key clinical and socio sanitary attributes and promote educational activities with patients with Diabetes Mellitus (DM) in a Family Health Care Unit of the Western Sanitary District, in the city of Natal / RN. It is an action research which uses the references of the Theory of Liberating Education, which is based on a problem-solving pedagogy and that values dialogue in the process of understanding oneself and the world. Thirty-six diabetics, who are residents of the area covered by the health care unit, and thirty health workers participated in the survey. Each group had an average of twelve participants, and the meetings took place at the Unit´s hall, using conversation wheels, group dynamics, life narratives, experiences telling, movie exhibition and discussions, music, knowledge telling, desires, limitations, beliefs and values socially constructed. Data collection took place during the second half of two thousand and thirteen through Free Word Association Technique (FWAT), recordings of conversation wheels, participative observation, group dynamics, testimonies, questionnaires, life narratives and photographs. The empirical material was organized and subjected to three analyzes: thematic content (Bardin), textual statistics analysis by software IRAMUTEQ (Ratinaud), and photographic analysis (Edmund Feldman). The data analyses originated words, expressions, categories, themes and creative situations showing that popular health education is in process of construction, but still very incipient in primary care. The National Policy on Popular Health Education shows us the necessary ways for the transformation of health practices and the build of a more shared and solidary society. The meetings could be place to reverse that normative logic that has been happening over the years in primary care, but that by itself is not enough. It is possible to conclude that the use of active practices, increasing of listening and training on Popular Health Education will enable changes in the scenario where users and health workers deal with diabetes mellitus. Thus we see the popular health education is being timidly incorporated to the educational process of the subjects involved in this study, and far away from the principles of participation, organization of political work, increase opportunities for dialogue, respect, solidarity and tolerance among different actors involved in addressing the health problems that are fundamental to the improvement in building healthy practices of primary care

Plant species identification using multi-scale fractal dimension applied to images of adaxial surface epidermis

This paper presents the study of computational methods applied to histological texture analysis in order to identify plant species, a very difficult task due to the great similarity among some species and presence of irregularities in a given species. Experiments were performed considering 300 ×300 texture windows extracted from adaxial surface epidermis from eight species. Different texture methods were evaluated using Linear Discriminant Analysis (LDA). Results showed that methods based on complexity analysis perform a better texture discrimination, so conducting to a more accurate identification of plant species. © 2009 Springer Berlin Heidelberg.

Vectorized algorithms for quadtree construction and descent

This paper presents vectorized methods of construction and descent of quadtrees that can be easily adapted to message passing parallel computing. A time complexity analysis for the present approach is also discussed. The proposed method of tree construction requires a hash table to index nodes of a linear quadtree in the breadth-first order. The hash is performed in two steps: an internal hash to index child nodes and an external hash to index nodes in the same level (depth). The quadtree descent is performed by considering each level as a vector segment of a linear quadtree, so that nodes of the same level can be processed concurrently. © 2012 Springer-Verlag.

A educação ambiental paraense na fala dos seus pioneiros

Comumente, as abordagens de Educação Ambiental (EA) são baseadas em discussões estabelecidas nos encontros que aconteceram fora do Pará. Levantar as experiências em nível local seria mais enriquecedor, uma vez que estaríamos tratando de assuntos pertinentes à nossa realidade e, portanto, mais atraente para os nossos alunos. Nesse contexto, levantei a minha questão de investigação: Como se deu a constituição da EA no Pará a partir do olhar dos seus pioneiros? Assim, tracei como objetivo desta dissertação: obter informações sobre o histórico da E A em nosso Estado, a partir da fala de seus pioneiros; caracterizar as concepções e as práxis presentes na estruturação de EA no Pará e verificar como é que os discursos de EA elaborados em escala mundial e nacional são compreendidos/entendidos pela fala dos pioneiros. Como instrumento investigativo, optei pela pesquisa qualitativa, baseada nas narrativas de cinco professores que se dedicaram/dedicam ao trabalho de implantação e de implementação da EA no estado do Pará e que estão ligados direta ou indiretamente à UFPA. Para coletados depoimentos, foram utilizadas entrevistas, com 12 questões semiestruturadas, gravadas em áudio, salvas em CD ROM e, posteriormente, transcritas. Além das entrevistas, lancei mão de meu diário de campo como fonte de informação, que foi construído ao longo da pesquisa por meio de percepções sobre os sujeitos e seus contextos, além dos registros de ocorrências diversas, no âmbito da pesquisa. Na busca da produção de novas compreensões das narrativas investigadas, apropriei-me da Análise Textual Discursiva para sistematizar as manifestações dos sujeitos, levando em consideração as peculiaridades e as singularidades de cada entrevistado, a qual deu forma a três eixos temáticos, que trato nesta investigação: i) O contexto dos educadores pioneiros em EA no Pará: constituição e práxis; ii) O cenário da criação da EA no estado do Pará e iii) Os paraenses com relação ao trato e ao relacionamento com o patrimônio ambiental: o resultado das bases fincadas. Na análise dos resultados foi possível constatar que eventos internacionais, associados à história da EA, ocorridos principalmente a partir da década de 1970, repercutiram intensamente nas formações dos entrevistados. Na mesma década, no estado do Pará, contatei várias ações de grupos pioneiros e iniciativas isoladas por parte do estado, o qual elaborou leis e programas, visando dar sistematicidade ao emprego de abordagens da EA. Neste contexto, considero que as estratégias historicamente utilizadas para a organização, implantação e difusão da EA em nosso estado - tanto em nível governamental como não governamental e no ensino formal e não formal -, foram elaboradas de forma desarticuladas e descontínuas. Considerei, como motivações para que os entrevistados iniciassem a jornada pelos caminhos da EA, os itens: relevância do meio ambiente para manutenção da vida no planeta e interesses pessoal e profissional. Por fim, percebi a grande contribuição que os entrevistados deram para a implantação e implementação da EA no Pará, quando em “seus agir” procuraram ressignificar os conhecimentos das determinações apregoadas nos documentos oficiais em EA, em nível mundial nacional e local, para lastrear as sua ações ambientalistas, na realidade paraense.

Collaborative fuzzy clustering algorithms: some refinements and design guidelines

There are some variants of the widely used Fuzzy C-Means (FCM) algorithm that support clustering data distributed across different sites. Those methods have been studied under different names, like collaborative and parallel fuzzy clustering. In this study, we offer some augmentation of the two FCM-based clustering algorithms used to cluster distributed data by arriving at some constructive ways of determining essential parameters of the algorithms (including the number of clusters) and forming a set of systematically structured guidelines such as a selection of the specific algorithm depending on the nature of the data environment and the assumptions being made about the number of clusters. A thorough complexity analysis, including space, time, and communication aspects, is reported. A series of detailed numeric experiments is used to illustrate the main ideas discussed in the study.

A note on DEA models in technology selection:an improvement of Karsak and Ahiska's approach

This paper introduces a compact form for the maximum value of the non-Archimedean in Data Envelopment Analysis (DEA) models applied for the technology selection, without the need to solve a linear programming (LP). Using this method the computational performance the common weight multi-criteria decision-making (MCDM) DEA model proposed by Karsak and Ahiska (International Journal of Production Research, 2005, 43(8), 1537-1554) is improved. This improvement is significant when computational issues and complexity analysis are a concern.

A novel detection method for determining a surgeon's fatigue and hand tremor

The thesis presents new methodology and algorithms that can be used to analyse and measure the hand tremor and fatigue of surgeons while performing surgery. This will assist them in deriving useful information about their fatigue levels, and make them aware of the changes in their tool point accuracies. This thesis proposes that muscular changes of surgeons, which occur through a day of operating, can be monitored using Electromyography (EMG) signals. The multi-channel EMG signals are measured at different muscles in the upper arm of surgeons. The dependence of EMG signals has been examined to test the hypothesis that EMG signals are coupled with and dependent on each other. The results demonstrated that EMG signals collected from different channels while mimicking an operating posture are independent. Consequently, single channel fatigue analysis has been performed. In measuring hand tremor, a new method for determining the maximum tremor amplitude using Principal Component Analysis (PCA) and a new technique to detrend acceleration signals using Empirical Mode Decomposition algorithm were introduced. This tremor determination method is more representative for surgeons and it is suggested as an alternative fatigue measure. This was combined with the complexity analysis method, and applied to surgically captured data to determine if operating has an effect on a surgeon’s fatigue and tremor levels. It was found that surgical tremor and fatigue are developed throughout a day of operating and that this could be determined based solely on their initial values. Finally, several Nonlinear AutoRegressive with eXogenous inputs (NARX) neural networks were evaluated. The results suggest that it is possible to monitor surgeon tremor variations during surgery from their EMG fatigue measurements.

Examining argumentative coherence in essays by undergraduate students of English as a foreign language in Mainland China and their English speaking peers in the United States

I conducted this study to provide insights toward deepening understanding of association between culture and writing by building, assessing, and refining a conceptual model of second language writing. To do this, I examined culture and coherence as well as the relationship between them through a mixed methods research design. Coherence has been an important and complex concept in ESL/EFL writing. I intended to study the concept of coherence in the research context of contrastive rhetoric, comparing the coherence quality in argumentative essays written by undergraduates in Mainland China and their U.S. peers. In order to analyze the complex concept of coherence, I synthesized five linguistic theories of coherence: Halliday and Hasan's cohesion theory, Carroll's theory of coherence, Enkvist's theory of coherence, Topical Structure Analysis, and Toulmin's Model. Based upon the synthesis, 16 variables were generated. Across these 16 variables, Hotelling t-test statistical analysis was conducted to predict differences in argumentative coherence between essays written by two groups of participants. In order to complement the statistical analysis, I conducted 30 interviews of the writers in the studies. Participants' responses were analyzed with open and axial coding. By analyzing the empirical data, I refined the conceptual model by adding more categories and establishing associations among them. The study found that U.S. students made use of more pronominal reference. Chinese students adopted more lexical devices of reiteration and extended paralleling progression. The interview data implied that the difference may be associated with the difference in linguistic features and rhetorical conventions in Chinese and English. As far as Toulmin's Model is concerned, Chinese students scored higher on data than their U.S. peers. According to the interview data, this may be due to the fact that Toulmin's Model, modified as three elements of arguments, have been widely and long taught in Chinese writing instruction while U.S. interview participants said that they were not taught to write essays according to Toulmin's Model. Implications were generated from the process of textual data analysis and the formulation of structural model defining coherence. These implications were aimed at informing writing instruction, assessment, peer-review, and self-revision.

Solving satisfiability, *implication, and equivalence problems in database systems

Satisfiability, implication and equivalence problems are important and widely-encountered database problems that need to be efficiently and effectively solved. We provide a comprehensive and systematic study of these problems. We consider three popular types of arithmetic inequalities, (X op C), (X op Y), and (X op Y + C), where X and Y are attributes, C is a constant of the domain of X, and op $\in\ \{{<},\ {\le},\ {=},\ {\not=},\ {>},\ {\ge}\}.$ These inequalities are most frequently used in a database system, since the first type of inequalities represents $\theta$-join, the second type represents selection, and the third type is popular in deductive databases. We study the problems under the integer domain and the real domain, as well as under two different operator sets.^ Our results show that solutions under different domains and/or different operator sets are quite different. In this dissertation, we either report the first necessary and sufficient conditions as well as their efficient algorithms with complexity analysis, or provide improved algorithms. ^

A representação discursiva da vítima e do réu no gênero sentença judicial

This dissertation aims to identify and describe the phenomenon of discursive representation of victim and defendant in court judgment genre. Researchis part of general theoretical framework of text linguistics and more specifically in textual discourse analysis (ATD) theory developed by Jean-Michel Adam ([2008] 2011). Discursive representation notion proposed by ATD is one of the most important aspects of semantic dimension of the text, being complemented in the work of Grize (1990, 1996) from schematization notion. In this perspective, this work is guided by studies of text linguistics with Koch (2012, 2005, 2004), Marcuschi (2012, 2008, 2005), Rodrigues, Passeggi and Silva Neto (2010, 2012, 2014), with genre Bazerman (2005), Bakhtin (1992) and the juridical discourse with Capez (2012), Pimenta (2007), Lourenço (2013) and Gomes (2013) . Methodologically, is a documentary research, presenting qualitative and descriptive characters and is guided by the inductivedeductive method. Corpus consists of a judicial sentence, criminal, collected electronically from Court of Justice of São Paulo - Judiciary website in consultation Judged1st Degree, with the theme of violence against women. Analysis procedures use semantic categories of discursive representation, such as referencing, predication, modification and the spatial and temporal location. Results are focused on the construction of discursive representation of (victim and defendant) from PdV distinct enunciators, which may approach or distance themselves according to argumentative text orientation. Thus, considering social importance of forensic text and, in particular, court judgment in the lives of citizens, it was possible to realize the importance of developing research that addresses the study of text semantic dimension, especially in construction of representations of discourse objects

A reforma psiquiátrica e a política de saúde mental do Rio Grande do Norte: papéis e funções de profissionais e gestores

This study arose from an interest in knowing the reality of mental health care in Rio Grande do Norte (RN) on the advances and challenges in the intersectoral agreements paths and consolidation of the Psychosocial Care Network (RAPS) from the state. Considering problematic and concerns were defined as objectives: Identify the knowledge of managers of Rio Grande do Norte on the National Mental Health Policy (PNSM) in the RN State; Describe the activities developed by health professionals in the individual service offered in the CAPS from RN; Understanding the relationship of managers’ knowledge on national mental health policy in professionals’ practice working in the the CAPS from the countryside. It is a descriptive study with a quantitative and qualitative approach, carried out in 30 CAPS from RN’s countryside, where 183 professionals answered a structured questionnaire with closed questions about the activities they do in individual care; and 19 mental health coordinators of municipalities and the state coordinator of RAPS were interviewed about their knowledge on the Mental Health Policy. Data were collected after approval by the Research Ethics Committee of the Federal University of Rio Grande do Norte, with the number 508.430 CAAE: 25851913.7.0000.5537 from August through October of 2014 in 26 municipalities with CAPS from the state. Quantitative data were tabulated and analyzed using a descriptive statistics aided by the software Statistical Package for the Social Scienses (SPSS) version 20.0. The qualitative data were prepared in a corpus and analyzed through software Analyse Lexicale par Contexte d’um Ensemble de Segments de Texte (ALCESTE) that allow to perform textual statistical analysis and categorization from their comments, submitted to Bardin content analysis. Five categories were generated approaching the managers’ knowledge, namely: Back to society: leadership and users’ role and autonomy; The gap between policy and practice; Barriers that affect the service; Structuring the Psychosocial Care Network; Multidisciplinary team: attribuitios and activities. The CAPS professionals’ ages ranged from 20 to 58 years, prevailing females, with 76.5% of the total, the majority were social workers (16.8%), psychologists (15.3%), nurses (14.8%) and nursing technicians (14.8%). The results showed precariousness in care associated with physical workload regard to high workload and low wages of the CAPS professionals' and, also, it was possible to observe a large involvement of professionals in care delivery, despite the difficulties encountered in services. It was found little knowledge in managers regarding the National Mental Health Policy having as causes of this reality the poor education and training of these professionals. The responses of professionals working in care reveals strong consistency with what is expected of a psychosocial care service. Points up as a thesis of this study that the psychiatric reform and mental health policy in Rio Grande do Norte is following a structural expansion process, but with precariousness of services from a still unprepared management to act in a psychosocial context.
