Comparacion de dos tecnicas anestesicas para legrado uterino

Metodología: se realizó un estudio descriptivo para evaluar las ventajas de la técnica regional sobre la técnica general en mujeres ASA 1 y 2 en Hospital Occidente de Kennedy. Se evaluaron los signos vitales, tiempo de recuperación, analgesia postoperatoria y efectos colaterales. Resultados: se incluyeron un total de 177 pacientes, 79 con anestesia regional y 98 pacientes con anestesia general. Los resultados en el postoperatorio mostraron que no hay diferencias estadísticamente significativas en cuanto a manejo de dolor, efectos colaterales, variación en signos vitales. Se encontró una diferencia significativa en el tiempo de recuperación p=0,02 siendo la técnica espinal 20 minutos en promedio más prolongada. Discusión: ambas técnicas suponen una buena opción como técnica anestésica para pacientes llevadas a legrado obstétrico, a pesar que el tiempo de recuperación fue mayor en el grupo de técnica espinal, se obtuvo un mejor manejo del dolor, sin el requerimiento de otros analgésicos durante el postoperatorio.

Existen diferencias farmacocinéticas y tiempos de despertar entre mujeres y hombres con anestesia total intravenosa

Introducción: La anestesia total intravenosa (TIVA) es ampliamente usada y reportada en la literatura como técnica para disminuir la respuesta a la laringoscopia e intubación, en la inducción y mantenimiento de una adecuada anestesia, además de una mejor estabilidad hemodinámica y recuperación pos anestésica; sin embargo no existen un gran número de estudios que comparen el uso de TIVA, determinando si existen diferencias en el perfil farmacocinético según el género del paciente. Objetivo: Describir diferencias farmacocinéticas y de los tiempos de despertar y salida a la unidad de cuidados pos anestésicos (descarga), según el género; en pacientes que reciben TIVA, con remifentanil y propofol, orientado por Stangraf. Metodología: Estudio observacional analítico de corte transversal, en pacientes llevados a cirugía bajo TIVA en el Hospital Occidente de Kennedy en el periodo de junio de 2013 a Enero de 2014.Usando SPSS versión 20 Windows, se analizaron los datos mediante pruebas Kolmogorov-Smirnov y Shapiro-Wilk y U de Mann Withney. Un valor de p menor 0.05 fue aceptado como estadísticamente significativo. Resultados: Se aplicaron pruebas de normalidad y no se encontraron diferencias estadísticamente significativas entre género. El tiempo de despertar fue 9.36 minutos para mujeres y 11.26 minutos para hombres. Los tiempos de descarga fueron 10.71 minutos para mujeres y 12.82 minutos para hombres. Discusión. El tiempo de despertar y descarga no es diferente entre mujeres y hombres en los pacientes analizados. Se requieren estudios adicionales entre grupos poblacionales de diversas condiciones farmacocineticas para corroborar los datos.

Defining a framework for the evaluation of information

In any enterprise, decisions need be made during the life cycle of information about its management. This requires information evaluation to take place; a little-understood process. For evaluation support to be both effective and resource efficient, some sort of automatic or semi-automatic evaluation method would be invaluable. Such a method would require an understanding of the diversity of the contexts in which evaluation takes place so that evaluation support can have the necessary context-sensitivity. This paper identifies the dimensions influencing the information evaluation process and defines the elements that characterise them, thus providing the foundations for a context-sensitive evaluation framework.

Resource allocation analysis of the stochastic diffusion search

The Stochastic Diffusion Search (SDS) was developed as a solution to the best-fit search problem. Thus, as a special case it is capable of solving the transform invariant pattern recognition problem. SDS is efficient and, although inherently probabilistic, produces very reliable solutions in widely ranging search conditions. However, to date a systematic formal investigation of its properties has not been carried out. This thesis addresses this problem. The thesis reports results pertaining to the global convergence of SDS as well as characterising its time complexity. However, the main emphasis of the work, reports on the resource allocation aspect of the Stochastic Diffusion Search operations. The thesis introduces a novel model of the algorithm, generalising an Ehrenfest Urn Model from statistical physics. This approach makes it possible to obtain a thorough characterisation of the response of the algorithm in terms of the parameters describing the search conditions in case of a unique best-fit pattern in the search space. This model is further generalised in order to account for different search conditions: two solutions in the search space and search for a unique solution in a noisy search space. Also an approximate solution in the case of two alternative solutions is proposed and compared with predictions of the extended Ehrenfest Urn model. The analysis performed enabled a quantitative characterisation of the Stochastic Diffusion Search in terms of exploration and exploitation of the search space. It appeared that SDS is biased towards the latter mode of operation. This novel perspective on the Stochastic Diffusion Search lead to an investigation of extensions of the standard SDS, which would strike a different balance between these two modes of search space processing. Thus, two novel algorithms were derived from the standard Stochastic Diffusion Search, ‘context-free’ and ‘context-sensitive’ SDS, and their properties were analysed with respect to resource allocation. It appeared that they shared some of the desired features of their predecessor but also possessed some properties not present in the classic SDS. The theory developed in the thesis was illustrated throughout with carefully chosen simulations of a best-fit search for a string pattern, a simple but representative domain, enabling careful control of search conditions.

Content validation for level of use of feature rich systems: a Delphi study of electronic medical records systems

Introduction. Feature usage is a pre-requisite to realising the benefits of investments in feature rich systems. We propose that conceptualising the dependent variable 'system use' as 'level of use' and specifying it as a formative construct has greater value for measuring the post-adoption use of feature rich systems. We then validate the content of the construct as a first step in developing a research instrument to measure it. The context of our study is the post-adoption use of electronic medical records (EMR) by primary care physicians. Method. Initially, a literature review of the empirical context defines the scope based on prior studies. Having identified core features from the literature, they are further refined with the help of experts in a consensus seeking process that follows the Delphi technique. Results.The methodology was successfully applied to EMRs, which were selected as an example of feature rich systems. A review of EMR usage and regulatory standards provided the feature input for the first round of the Delphi process. A panel of experts then reached consensus after four rounds, identifying ten task-based features that would be indicators of level of use. Conclusions. To study why some users deploy more advanced features than others, theories of post-adoption require a rich formative dependent variable that measures level of use. We have demonstrated that a context sensitive literature review followed by refinement through a consensus seeking process is a suitable methodology to validate the content of this dependent variable. This is the first step of instrument development prior to statistical confirmation with a larger sample.

Communicating uncertainties in sea surface temperature

A project on sea surface temperature is generating new climate data records from satellite observations. The data are independent of in situ observations and are harmonious across satellite sensors to maximize stability and have realistic, context-sensitive uncertainty estimates at all spatial and temporal scales. The project, part of the European Space Agency Climate Change Initiative (SST CCI), now seeks to establish a useful method for communicating uncertainty in sea surface temperatures. This goal was the impetus for a workshop held in November 2014 in Exeter in the United Kingdom, summarised in this article.

Contemporary Approaches to Translation in the Classroom : A study of students' Attitudes and Strategies

The purpose of this study is to explore the strategies and attitudes of students towards translation in the context of language learning. The informants come from two different classes at an Upper Secondary vocational program. The study was born from the backdrop of discussions among some English teachers representing different theories on translation and language learning, meeting students endeavoring in language learning beyond the confinement of the classroom and personal experiences of translation in language learning. The curriculum and course plan for English at the vocational program emphasize two things of particular interest to our study; integration of the program outcomes and vocational language into the English course - so called meshed learning – and student awareness of their own learning processes. A background is presented of different contrasting methods in translation and language learning that is relevant to our discussion. However, focus is given to contemporary research on reforms within the Comparative Theory, as expressed in Translation in Language and Teaching (TILT), Contrastive Analysis and “The Third Space”. The results of the students’ reflections are presented as attempts to translate two different texts; one lyric and one technical vocational text. The results show a pragmatic attitude among the students toward tools like dictionaries or Google Translate, but also a critical awareness about their use and limits. They appear to prefer the use of first language to the target language when discussing the correct translation as they sought accuracy over meaning. Translation for them was a natural and problem-solving event worth a rightful place in language teaching.

Utmaningen från andra berättelser : En studie om moraliskt omdöme, utvidgat tänkande och kritiskt reflekterande berättelser i dialogbaserad feministisk etik

The present study has a threefold aim: First, the theoretical aim is to give a contribution to refinement of the theory of dialogue based feminist ethics, concerning the understanding of judgment and narration within such an ethics.  The study also has an empirical aim, defined as to clarify what kind of knowledge, relevant to the moral judgment of an engaged outsider actor, can be received from dialogical interpretation and analysis of a limited selection of critically reflecting life stories. Third, a methodological aim is defined as to develop an approach to interpretation and analysis of reflecting life stories, which renders the storyteller visible as a reflecting moral subject, and makes the story accessible as a source of knowledge for the moral judgment of an engaged outsider actor. The thesis combines philosophical reflection and argumentation, with a narrative-hermeneutic method for interpretation of life stories, relating the two to each other in a hermeneutic process.  The theoretical reflection draws on Seyla Benhabibs theory of communicative ethics. A dialogue based model for moral justification and a likewise dialogue based model for political legitimacy are at the heart of this universalistic theory, although in combination with a conception of a narratively and hermeneutically constituted context sensitive moral judgment, based on Hannah Arendt’s concept “enlarged thought”. In the reflection, this model is related to other feminist theorizing within the tradition of dialogue based feminist ethics, as found in the works of Iris M. Young, Georgia Warnke and Shari Stone-Mediatore. The empirical study draws on three critically reflecting life stories from Israeli-Palestinian women activists for a just peace. The methodology for interpretation and analysis that is worked out combines dialogical interpretation as presented in Arthur W. Frank’s socio-narratology with a method for structural analysis derived from Shari Stone-Mediatores theory of storytelling as an expression of political resistance struggle. The results show that some stories drawing on marginalized experiences have a potential­ to stimulate further public debate through their capacity to enable a stereoscopic seeing, elucidating a tension between ideologically structured discourse and non-linguistic experience; implying that narrative-hermeneutic competence should be considered crucial for public debate.  

O Corpo do grupo corpo: os movimentos das obras Benguelê, Lecuona e Onqotô

In this research, we invite to reflection by a phenomenological gaze on the body, through the description of some works of contemporary Brazilian dance company Grupo Corpo. This Company was chosen intentionally to give us elements in their creations to interrogate the understanding of the body and sensitive. Thus, as we launch issues in this dissertation: that body dance in Grupo Corpo? And as we can see, a phenomenological approach, an understanding of the body and sensitive works in that company? Building on this, the works are to be questioned Benguelê (1998/2003), Lecuona (2004) and Onqotô (2005). It is intended, through these works, coreological approaching the discourse of philosophical discourse and give movement to phenomenological thought of Maurice Merleau-Ponty, in special the sensitive, flesh of the body, the investment in the sensory world as a merger, calling the know body and its power to take chances, to incorporate the world, language, culture, create and choose. Thus, these openings is where thought enters this research. This consistency, we used the phenomenological attitude of Maurice Merleau-Ponty as a methodological approach, since in their study the philosopher takes a look expressive on the body, forming a sensitive language that is expressed in the movements, which deepens the arguments of the Phenomenology a new arrangement for knowledge as a result of our experience in the lived world. The reflections presented here aim to take us to the amazement, the unthinking, whom many still impose epistemological challenges, including understanding the body of knowledge and sensitive

As construções adverbiais em mente: análise funcionalista e implicações para o ensino de língua materna

This research aims at investigating the constructions with adverbials in ly, based on the view of contemporaneous linguistic functionalism, such as proposed by Givón, Hopper, Thompson, Traugott, Furtado da Cunha, as well as the cognitivist notion of language, through construction grammar support upon the patterns of Goldberg and the prototypes theory. The cognitive functional approach adopted here considers the change as a proper and inherent phenomenon of language and understands the linguistic phenomenon as resulting from effective use of language. Another aspect to be considered to the realization of this study is the fact that the formation adjective + ly is a word construction mechanism really productive, which generates interests on linguistic description. In a particular way, our leading objective is to exam the constructions with adverbials in ly in the context of language in use, in its oral and written forms, looking for to apprehend the meaning multiple manifestations forged in the use. Bearing this in mind, we worked with data from the Corpus Discurso & Gramática (Natal). There are, in the data, adverbs ended in ly that take the signification of mode, as foreseen in traditional models, but there are also other significations, for instance, the modalizador in its different manifestations. The results show that this adverb is a linguistic mark that carries in its constitution the multissêmico and multifunctional character, which interferes extremely in the ordination of this category, assuming a position sometimes pre-verbal, sometimes post-verbal. Other aspect observed refers to the relationship between the adverb and the verb, with emphasis on the compatibility or restriction between them, option which is related to the semantic aspect. The data in analysis legitimate the use in different constructions with adverb ended in ly in various genres, as follows: personal experience narrative, retold narrative, local description, proceeding account, opinion account, both in oral as in written language

Procedimentos de abertura e fechamento de tópicos na interação em sala de aula

This study is part of interactional perspective, focusing on Conversation Analysis theories, from the Textual Interactive Perspective and Text Linguistics . This research, from its guiding questions, aims at understanding the interaction between teacher and students in the process of the knowledge construction as well as at describing, analyzing and understanding aspects of topical organization speech in the classroom in elementary school, observing the opening and closing procedures of the speech topics in that particular space. Considering that the procedures for opening and closing of discursive topics occur through language marks, we tried to identify which speech marks are used in the opening and closing of the topics studied in the classroom, in interaction during the collaborative process of the discourse established between teacher and students. Therefore, this study is based on authors who analyze specific questions of the text in real context of language use: Koch (1993, 1999), Jubran et al (1991), Jubran (2006), Pine (2005), Penhavel (2010), Galembeck (2012), Barros (1991), Marcuschi (1986 , 1990, 1991 , 1998 , 1999, 2003 , 2004a), Kerbrat - Orecchioni (2006), Favero (1999, 2002) and Galvão (2004, 2010). As a methodology of investigation, the study is focused on the postulates of ethnographic research in order to carry out data collection, through audio and video recordings which were transcribed, according to the NURC project proposal, with some adaptations. Data analysis showed that the procedures for opening and closing of the speech topics occurred by the use of discourse markers, in particular the marker "then", allowing us to understand that these elements are important in the topical organization speech, contributing to ensure textual cohesion and coherence. We conclude that the organization of the discursive topic in the classroom occurs through events that support the explicitness of the content of teaching and learning, considering the diverse necessity of an institutional academic plan, whose main objective is the construction of knowledge

Reqsys-MDD: uma ferramenta para mapeamento entre modelos de features e requisitos em linhas de produto de software

The approach Software Product Line (SPL) has become very promising these days, since it allows the production of customized systems on large scale through product families. For the modeling of these families the Features Model is being widely used, however, it is a model that has low level of detail and not may be sufficient to guide the development team of LPS. Thus, it is recommended add the Features Model to other models representing the system from other perspectives. The goals model PL-AOVgraph can assume this role complementary to the Features Model, since it has a to context oriented language of LPS's, which allows the requirements modeling in detail and identification of crosscutting concerns that may arise as result of variability. In order to insert PL-AOVgraph in development of LPS's, this paper proposes a bi-directional mapping between PL-AOVgraph and Features Model, which will be automated by tool ReqSys-MDD. This tool uses the approach of Model-Driven Development (MDD), which allows the construction of systems from high level models through successive transformations. This enables the integration of ReqSys-MDD with other tools MDD that use their output models as input to other transformations. So it is possible keep consistency among the models involved, avoiding loss of informations on transitions between stages of development

Aprendizagem de línguas e léxico: a negociação de significado em práticas telecolaborativas

This paper is a qualitative ethnographic study that aims to present reflections on negotiation events in teletandem interactions, a synchronous telecollaborative context of language learning, within the scope of the interaction strategies adopted by participants to achieve comprehensibility. The project Teletandem Brasil: foreign languages for all (Telles, 2006) matches up native or proficient speakers of a foreign language with Brazilian undergraduate students to learn each other's language, by communicating synchronically with application softwares like Skype, Oovoo or MSN. on this paper, based on the interpretive perspective of Hermeneutics, we analyze excerpts of teletandem interactions of partnerships established between students of a Brazilian university and American universities. The excerpts presented here have been taken from different moments of the research studies conducted at the teletandem laboratories of UNESP Assis and Sao Jose do Rio Preto and are part of the database of the works of Santos (2008) and Garcia (2010). In this article, in the data analysis, we highlight the focus on form and on lexicon as characteristics of the interactions and analyze how the negotiations happen in this learning context mediated by technology. Among results we may highlight the prevailing of external feedback as a trigger to negotiation moves, the occurrence of adjustment processes between participants to get adapted to each other's interaction behavior, as well as the evolution of this behavior as interactants get familiarized with the computer-mediated communication context, under the shape of changes in the participants choices regarding negotiation of meaning along their interaction experience.
