Learning analytics in practice: setting up a laboratory for action research at the Universitat Oberta de Catalunya

Since its inception in 1994 as a purely online university, the Universitat Oberta de Catalunya(UOC) has been able to position itself among the main universities of the Catalan and Spanish university systems. Most of the students at the UOC (currently more than 60,000) are adults who have a profile that could hardly fit into the traditional university system, thus finding in the UOC an opportunity to start or continue their higher education grades, in a very innovative environment. The intensive use of ICT for both theteaching/learning processes and management allowsresearchers and practitioners to obtain data aboutwhat takes place in the UOC Virtual Campus, which is continuously being improved according to suchfindings.

La construcción narrativa de la identidad en un contexto educativo intercultural = The narrative construction of identity in a intercultural educative setting

En este trabajo se expone e ilustra un modelo teórico para entender las funciones de la identidad, así como los mecanismospsicosociales asociados a su construcción: “Modelo Evolutivo y Funcional de la Identidad Mediada” (MEBIM). La identidad, mediada narrativamente, cumple una función personal orientada a la dirección de la propia vida, así como una función sociocultural vinculada a la búsqueda de reconocimiento de los derechos de los grupos sociales a los que uno se siente apegado. Se ilustran los factores asociados a la construcción de la identidad personal (sí mismos posibles, transiciones vitales, vínculo afectivo) y sociocultural (acción-transformación e identificación simbólica) a partir de 12 historias de vida realizadas con mestizos e indígenasde la Universidad Intercultural de Chiapas (México). Se sugiere que en contextos educativos formales, como la escuela o la Universidad, se deben propiciar narrativas personales y socioculturales con el objetivo de optimizar la identidad en un mundo a la vez globalizado y plural

Agenda de proves diagnòstiques

El TFC neix d'una necessitat real, d'una empresa privada del sector sanitari, la qual ens requereix crear una aplicació web que anomenarem "Agenda de proves diagnòstiques" que ens servirà per monitoritzar quin és l'estat actual en què es troben les visites que han arribat al centre per poder assignar-li els recursos necessaris (Dr./Dra. i sala d'exploració).

Un análisis comparativo del papel del bucle fonológico versus la agenda visoespacial en el cálculo en niños de 7-8 años = A comparative analysis of the phonological loop versus the visuo-spatial sketchpad in mental arithmetic tasks in 7-8 y.o. children

En esta investigación se ha estudiado la relación entre dos subsistemas de la memoria de trabajo (buclefonológico y agenda viso-espacial) y el rendimiento en cálculo con una muestra de 94 niños españolesde 7-8 años. Hemos administrado dos pruebas de cálculo diseñadas para este estudio y seis medidassimples de memoria de trabajo (de contenido verbal, numérico y espacial) de la «Batería de Testsde Memoria de Treball» de Pickering, Baqués y Gathercole (1999), y dos pruebas visuales complementarias.Los resultados muestran una correlación importante entre las medidas de contenido verbaly numérico y el rendimiento en cálculo. En cambio, no hemos encontrado ninguna relación con las medidasespaciales. Se concluye, por lo tanto, que en escolares españoles existe una relación importanteentre el bucle fonológico y el rendimiento en tareas de cálculo. En cambio, el rol de la agenda viso-espaciales nulo

Setting priorities in clinical and health services research: Properties of an adapted and updated method

Objectives: The objectives of this study is to review the set of criteria of the Institute of Medicine (IOM) for priority-setting in research with addition of new criteria if necessary, and to develop and evaluate the reliability and validity of the final priority score. Methods: Based on the evaluation of 199 research topics, forty-five experts identified additional criteria for priority-setting, rated their relevance, and ranked and weighted them in a three-round modified Delphi technique. A final priority score was developed and evaluated. Internal consistency, test–retest and inter-rater reliability were assessed. Correlation with experts’ overall qualitative topic ratings were assessed as an approximation to validity. Results: All seven original IOM criteria were considered relevant and two new criteria were added (“potential for translation into practice”, and “need for knowledge”). Final ranks and relative weights differed from those of the original IOM criteria: “research impact on health outcomes” was considered the most important criterion (4.23), as opposed to “burden of disease” (3.92). Cronbach’s alpha (0.75) and test–retest stability (interclass correlation coefficient = 0.66) for the final set of criteria were acceptable. The area under the receiver operating characteristic curve for overall assessment of priority was 0.66. Conclusions: A reliable instrument for prioritizing topics in clinical and health services research has been developed. Further evaluation of its validity and impact on selecting research topics is required

Salesperson's customer orientation in the personal selling process and in the use of personal selling techniques in the business-to-business setting

Selling is much maligned, often under-valued subject whose inadequate showing in business schools is in inverse proportion to the many job opportunities it offers and the importance of salespeople bringing incomes to companies. The purpose of this research is to increase the understanding of customer-oriented selling and examine the influence of customer-oriented philosophy on selling process, the applicability of selling techniques to this philosophy and the importance of them to salespeople. The empirical section of the study is two-fold. Firstly, the data of qualitative part was collected by conducting five thematic interviews among sales consultants and case company representatives. The findings of the study indicate that customer-oriented selling requires the activity of salespeople. In the customer-oriented personal selling process, salespeople invest time in the preplanning, the need analysis and the benefit demonstration stages. However, the findings propose that salespeople today must also have the basic capabilities for executing the traditional sales process, and the balance between traditional and consultative selling process will change as the duration of the relationship between the salesperson and customer increases. The study also proposes that selling techniques still belong to the customer-oriented selling process, although their roles might be modest. This thesis mapped 75 selling techniques and the quantitative part of the study explored what selling techniques are considered to be important by salespeople in direct selling industry when they make sales with new and existing customers. Response rate of the survey was 69.5%.

Generic and professional caring in a Chinese setting: an ethnopraphic study

The objective of the present study is to describe the cultural care practices, meanings, values and beliefs which form the basis of caring in a Chinese context. The research has its starting point in a caring science perspective and a qualitative research approach with interpretative ethnography as methodological guideline. The theoretical perspective is formed by elements of the theory of caritative caring, developed by Eriksson, and the theory of Culture Care Diversity and Universality, developed by Leininger. Previous research of suffering, culture and caring is described and also a presentation of actual transcultural nursing research as well as a presentation of the social structure dimensions of Chinese culture is included in the theoretical background. The empirical part includes patients and relatives, nurses and Hu Gongs as informants. The data collected are analysed based on Geertz’s idea of forming “thick descriptions” through examining the “what, how and why” of people’s actions. The findings show that the family has a prominent position in Chinese caring practices. The patient plays an unobtrusive role and a mutual dependence between the patient and the family members is evident. The professional nursing care is an extended act which includes the family in the caring relationship. The care practices of the Chinese nurse are characterized by great professional nursing skills. Suffering is described by the informants as being caused by disease, pain and social circumstances. “Social suffering” is described as worse than physical or mental suffering. Culturally competent and congruent care is a prerequisite for avoiding cultural pain, imposition and blindness when caring for the suffering human being. The findings of the present study necessitate a broadening in caring theory to include the family in the caring relationship. A further conclusion is that a broadening in our perception and understanding of culture would promote the delivery of culturally competent and congruent care. Suffering need to be seen as enclosed in cultural patterns of how it is expressed, interpreted, understood and relieved. Care and caring need to be seen as embedded in culture and the care practices values and beliefs have to be congruent with the cultural patterns where the care is provided.

Interesse dos estudantes pela medicina de família: estado da questão e agenda de pesquisa

Com a criação e a expansão do Programa Saúde da Família no Brasil, a Medicina de Família e Comunidade (MFC), como especialidade médica, ganhou destaque por ser a mais adequada a esse trabalho. Recentes parcerias entre os ministérios da Saúde e da Educação têm procurado regular a formação de recursos humanos em saúde para atender às demandas de consolidação do Sistema Único de Saúde (SUS) no âmbito da graduação e da pós-graduação. Houve investimento no aumento no número de vagas de residência em MFC, mas parece haver uma incongruência entre o que os futuros médicos almejam em suas carreiras e as necessidades do SUS, o que é demonstrado pelo número de vagas ociosas nesses programas. Com o objetivo de elencar hipóteses explicativas do desinteresse por essa especialidade, fizemos uma revisão de trabalhos que enfocaram essa temática. Encontramos que pouco prestígio, baixos salários, pouca vivência em atenção primária durante a graduação e elevada dívida com a universidade foram os fatores mais recorrentes. Concluímos que é necessário investigar essas hipóteses em nossa realidade, motivo pelo qual propomos uma agenda de pesquisa nessa direção.

Studies in offset ink setting

The offset printing process is complex and involves the meeting of two essentially complex materials, printing ink and paper, upon which the final product is formed. It can therefore be expected that a multitude of chemical and physical interactions and mechanisms take place at the ink-paper interface. Interactions between ink and paper are of interest to both the papermakers and ink producers, as they wish to achieve better quality in the final product. The objective of this work is to clarify the combined influence of paper coating structure, printing ink and fountain solution on ink setting and the problems related to ink setting. A further aim is to identify the mechanisms that influence ink setting problems, and to be able to counteract them by changing properties of the coating layer or by changing the properties of the ink. The work carried out for this thesis included use of many techniques ranging from standard paper and printability tests to advanced optical techniques for detection of ink filaments during ink levelling. Modern imaging methods were applied for assessment of ink filament remain sizes and distribution of ink components inside pigment coating layers. Gravimetric filtration method and assessment of print rub using Ink-Surface-Interaction-Tester (ISIT) were utilized to study the influence of ink properties on ink setting. The chemical interactions were observed with the help of modified thin layer chromatography and contact angle measurements using both conventional and high speed imaging. The results of the papers in this thesis link the press operational parameters to filament sizes and show the influence of these parameters to filament size distribution. The relative importance between the press operation parameters was shown to vary. The size distribution of filaments is important in predicting the ink setting behaviour, which was highlighted by the dynamic gloss and ink setting studies. Prediction of ink setting behaviour was also further improved by use of separate permeability factors for different ink types in connection to filtration equations. The roles of ink components were studied in connection to ink absorption and mechanism of print rub. Total solids content and ratio of linseed oil to mineral oil were found to determine the degree of print rub on coated papers. Wax addition improved print rub resistance, but would not decrease print rub as much as lowering the total solids content in the ink. Linseed oil was shown to absorb into pigment coating pores by mechanism of adsorption to pore walls, which highlights the need for sufficient pore surface area for improved chromatographic separation of ink components. These results should help press operators, suppliers of printing presses, papermakers and suppliers to papermakers, to better understand the material and operating conditions of the press as it relates to various print quality issues. Even though paper is in competition with electronic media, high quality printed products are still in demand. The results should provide useful information for this segment of the industry.

Setting efficiency indicators for center pivots

In this study, it was discussed the efficiency criteria in each of the elements that compose a central pivot, and this analysis was applied to two sets of systems located in regions of Cruz Alta and Santo Augusto, state of Rio Grande do Sul, Brazil. The methodology used combines water and energy assessment through an indicator called Normalized Specific Consumption in Irrigation (C ENI), allowing thus a comparison between equipment and projects. The C ENI in Cruz Alta region showed 72% of the equipment above the standard (8.68 kWh mm-1 ha-1 100m-1), and in Santo Augusto region 64.28% with consumption above the standard. The mean irrigation efficiency for Cruz Alta region was 29.85%, with standard deviation of 5.41%, and for Santo Augusto region, it was 29.02%, with standard deviation of 5.15%.
