The background impact in HEI math lectures: an experience in math in the 1st year of Accounting and Management Degree

It is a fact, and far from being a new one, that students have been entering Higher Education courses with many different backgrounds in terms of secondary school programs they attended. The impact of these basic skills is a general and worldwide challenge, fundamentally when facing some specific “constructive” subjects like foreign languages and Mathematics. Working with students with an extensive variety of Math qualifications is an outrageous challenge when they enter an advanced Math course, leading to an almost generalized expectations’ failure - from students enrolled in course and from their teachers, who feel powerless in trying to monitor knowledge construction from completely different “starting points”. If teachers’ "haste" is average, more than half of the students do not “go along” and give up, even before experiencing any kind of evaluation procedure. On the contrary, if the “speed” is too low, others are discouraged (feeling not progressing at all) and the teacher runs the risk of not meeting the minimum objectives (general and specific) of its course, which may have a negative impact on students’ future training development. Failure in Mathematics, despite being a recurrent and global issue, does not have any “magical solution”, however, in general, teachers in this area seem untiring, searching, investigating, trying and implementing new and old “recipes” to tackle and demystify this subject. In this article we describe a project developed in a Math course, with the first year students from an Accounting and Management bachelor degree, and its outcomes since it was brought to practice, revealing its impact in students’ success, from approval to dropout rates, in this course. We will shortly describe students’ differentiated Math backgrounds, their results in a pre-assessment analysis and how we try to deal with these differences and level them up, having in mind the same “finish line”. One should never forget that all these students where officially accepted in higher education institutions, so they are ones’ reality, the reality of institutions whose name one should value and strive to defend.

Diseño e implementación de un sistema de soporte de decisiones para el Centro de Documentación Regional “Juan Bautista Vázquez”

El volumen de datos en bibliotecas ha aumentado enormemente en los últimos años, así como también la complejidad de sus fuentes y formatos de información, dificultando su gestión y acceso, especialmente como apoyo en la toma de decisiones. Sabiendo que una buena gestión de bibliotecas involucra la integración de indicadores estratégicos, la implementación de un Data Warehouse (DW), que gestione adecuadamente tal cantidad de información, así como su compleja mezcla de fuentes de datos, se convierte en una alternativa interesante a considerar. El artículo describe el diseño e implementación de un sistema de soporte de decisiones (DSS) basado en técnicas de DW para la biblioteca de la Universidad de Cuenca. Para esto, el estudio utiliza una metodología holística, propuesto por Siguenza-Guzman et al. (2014) para la evaluación integral de bibliotecas. Dicha metodología evalúa la colección y los servicios, incorporando importantes elementos para la gestión de bibliotecas, tales como: el desempeño de los servicios, el control de calidad, el uso de la colección y la interacción con el usuario. A partir de este análisis, se propone una arquitectura de DW que integra, procesa y almacena los datos. Finalmente, estos datos almacenados son analizados y visualizados a través de herramientas de procesamiento analítico en línea (OLAP). Las pruebas iniciales de implementación confirman la viabilidad y eficacia del enfoque propuesto, al integrar con éxito múltiples y heterogéneas fuentes y formatos de datos, facilitando que los directores de bibliotecas generen informes personalizados, e incluso permitiendo madurar los procesos transaccionales que diariamente se llevan a cabo.

Despliegue de escenarios de entrenamiento en seguridad utilizando técnicas de virtualización con clonado rápido

La formación y preparación constante del personal de TI es una de las estrategias más efectivas para mejorar la calidad, estabilidad y seguridad de las redes y servicios asociados. En esta línea, el CEDIA ha venido implementando cursos y talleres de capacitación dirigidos a sus miembros y, dentro del CSIRT-CEDIA, se ha pensado en la posibilidad de optimizar los procesos asociados al despliegue de la infraestructura necesaria para proveer a los participantes de éstas capacitaciones, con el material personalizado adecuado, en las áreas de seguridad informática. Es así que se decidió usar técnicas de virtualización para aprovechar los recursos disponibles, pero aun cuando esto en sí no es una tendencia nueva, el uso de una copia completa del disco virtual para cada participante, no sólo resulta impráctico en cuestión de tiempo, sino también en cuanto al consumo de almacenamiento necesario. Este trabajo se orienta justamente a la optimización en los tiempos y consumos asociados a los procesos de replicación de un mismo equipo y disco virtuales para uso particularizado de varios participantes.

Qualidade nos serviços turísticos náuticos no Alto Douro Vinhateiro: perspetiva dos clientes internos (colaboradores)

No contexto atual, marcado pela crise económica e financeira, as organizações dos serviços turísticos procuram aliar o conceito de qualidade com os seus serviços, de modo a satisfazer os clientes internos (colaboradores) e os clientes externos (turistas) e a garantir a prestação de um serviço personalizado e de excelência. O objetivo da presente dissertação consiste em proporcionar uma visão geral da qualidade dos serviços turísticos náuticos efetuados na região do Alto Douro Vinhateiro (ADV), junto dos clientes internos (colaboradores). Para o efeito, foi aplicado um inquérito a 117 colaboradores de diversas organizações dos serviços turísticos náuticos da região do ADV e realizada uma pesquisa exploratória e descritiva. Os resultados obtidos demonstram que existem aspetos a serem melhorados nas organizações (preocupação com os colaboradores; formação especifica; condições de trabalho; maior dialogo entre chefias e colaboradores; atribuição de carga horária e de folgas) para que os colaboradores se sintam satisfeitos. Por outro lado, verificou-se que as perceções sobre a qualidade nos serviços turísticos náuticos são iguais em ambos os géneros; Abstract: Quality in Nautical Touristic Services in Alto Douro Vinhateiro – The Internal Clients (Collaborators) Perspective In the actual context marked by the economic and financial crisis, the organizations of touristic services are looking to ally the concept of services with their services, in order to satisfy internal customers (collaborators) and external costumers (tourists) and to guarantee the installment of an excellent and personalized service. The aim of this thesis is to provide an overview of the quality of nautical tourism services made in the region of Alto Douro Vinhateiro, with internal clients (employees). For this purpose it applied a survey of 117 employees from various organizations of nautical tourism services of the ADV region and conducted an exploratory and descriptive research. The results show that there are areas to be improved in organizations (preoccupation with employees; specific training,; working conditions; greater dialogue between managers and employees; allocation of hours and days off) so that employees can feel satisfied- Moreover it was found that the perceptions of the quality of nautical tourism services are equal in both sexes.

Projeto Fénix : inovação na organização pedagógica no 1º ciclo : estudo de caso

A dissertação que aqui se apresenta resulta de um trabalho de investigação junto de um Agrupamento de Escolas que adotou, a partir do ano letivo 2011/2012, como medida de promoção de sucesso educativo, o Projeto Fénix. Teoricamente, este estudo pretendeu analisar a escola enquanto organização social em que a comunidade escolar e social são partes interessadas na inovação e na mudança; esclarecer o conceito de projeto nos quadros dos novos regimes de autonomia e de gestão das escolas; compreender a importância e o papel dos projetos educacionais como fatores promotores de mudança e inovação pedagógica nas organizações escolares. Assim, adotando uma metodologia de trabalho de caráter qualitativo, descritivo e interpretativo procurou-se, através de um estudo de caso, analisar as medidas organizacionais que a escola assumiu para dar um apoio mais personalizado aos alunos que evidenciavam dificuldades de aprendizagem, nomeadamente, na disciplina de português; de que forma se procedeu à sua implementação na prática diária e o impacto do projeto nos professores e alunos; e, ao mesmo tempo analisar a relevância e o sentido da avaliação no decorrer e no término de um projeto, como importante processo de apoio à transformação, à melhoria, à transparência, no desenvolvimento de projetos educativos. A concretização destes objetivos só foi possível graças à colaboração da direção do agrupamento que autorizou a consulta de vários documentos essenciais e de todos os outros intervenientes no processo (alunos, professores, diretora, coordenadores e encarregados de educação), que prontamente se disponibilizaram para responderem às entrevistas. Sucintamente pode dizer-se que o estudo permitiu perceber que a implementação do Projeto Fénix, no geral, foi bem aceite por toda a comunidade educativa, mesmo tratando-se de um desafio ambicioso que exigiu determinação, rigor e trabalho de equipa, no qual alunos, professores e pais se comprometeram a melhorar o sucesso educativo. Apesar dos entraves que surgiram em consequência das políticas economicistas e de contenção, do quadro político atual, e da falta de recursos humanos (bolsa de professores de apoio), a nova organização pedagógica fundamentada pelo Projeto Fénix conseguiu melhorar o clima de aprendizagem, recuperar os alunos com mais dificuldades de aprendizagem e aprimorar as excelências.

Eph kinases and their ligands ephrins act in concert with sex hormones in regulating blood pressure

Les Erythropoietin-producing hepatocyte (EPH) sont la plus grande famille de récepteurs tyrosine kinase. Leurs ligands, les éphrines (EFNs), sont aussi des molécules exprimées à la surface cellulaire. Les EPH/EFNs sont impliqués dans de nombreux processus biologiques. L'hypertension artérielle (PA) est une maladie chronique qui, aujourd'hui, est devenue un problème médical critique dans le monde entier et un enjeu de santé publique. La découverte de nouvelles thérapeutiques de l'hypertension sont d'une grande importance pour la santé publique. Jusqu’à tout récemment, il existe seulement quelques études concernant le rôle de l’axe EPH/EFNs sur la fonction des cellules musculaires lisses vasculaires (CMLV). Dans nos études précédentes, nous avons montré qu'EPHB6 et EFNB1, de concert avec les hormones sexuelles, régulent la PA. Dans la présente étude, nous avons constaté que les différents membres de la famille EPH/EFN peuvent réguler soit positivement, soit négativement, la contractilité des CMLV et la PA: tandis que EPHB4 et EFNB2 appartiennent à la première catégorie, EFNB1, EFNB3 et EPHB6 appartiennent à la deuxième. In vivo, des souris males, mais non pas des femelles, porteuses d’une mutation EPHB4 (KO) spécifique du muscle lisse présentent une PA diminuée, comparée aux souris témoins (WT). Les CMLV de souris EPHB4 KO, en présence de testostérone, ont montré une contractilité réduite lors de la stimulation par la phényléphrine (PE). Au niveau moléculaire, la phosphorylation de la protéine kinase II dépendante de Ca2+/calmoduline et de la kinase de la chaine légère de la myosine (CLM) est augmentée, tandis que la phosphorylation de la kinase de la CLM est réduite dans les CMLV KO lors de la stimulation par PE, par rapport au WT CMLV. Cela fournit une base moléculaire à la réduction de la PA et de la contractilité des CMLV chez les souris EPHB4 KO. EFNB2 est le ligand majeur de l’EPHB4. Comme attendu, les souris EFNB2 KO spécifique du muscle lisse avaient un phénotype de PA semblable, quoique non identique, aux souris EPHB4 KO. Les souris mâles EFNB2 KO, mais pas femelles, sous régime régulier ou riche en sel, présentent une PA réduite, par rapport à leurs homologues WT. Au niveau cellulaire, les CMLV des souris KO ont montré une contractilité réduite lors de la stimulation par PE par rapport aux témoins WT. Une région de l’acide aminé (aa) 313 à l’aa 331 dans la partie intracellulaire d’EFNB2 est essentielle pour la signalisation inverse qui régule la contractilité des CMLV, selon des études de mutation-délétion. Dans une étude de génétique humaine, nous avons identifié, dans le gène EFNB2, six SNP qui étaient associées significativement au risque d'hypertension artérielle, de façon dépendante du sexe, ce qui corrobore nos résultats chez les souris. En revanche, la délétion du gène EFNB3 (KO) chez les souris femelles aboutit à une PA élevée et à une augmentation des résistances des petites artères in vivo, améliore la contractilité des petites artères ex-vivo et augmente la contractilité des CMLV in vitro. Les souris mâles KO ont une PA normale, mais la castration conduit à une augmentation significative de la PA dans les souris KO, mais pas dans les souris WT. Les CMLV des souris KO femelles ont montré une phosphorylation accrue de la CLM et une phosphorylation réduite de la kinase de la CLM, ce qui fournit à nouveau une base moléculaire aux phénotypes de PA et de contractilité des CMLV observés. Ce changement de signalisation est attribuable à une protéine adaptatrice Grip1. En effet, dans une étude d'association pan génomique par le Consortium International pour la Pression Sanguine, un SNP dans le gène GRIP1 a approché le seuil de significativité de la valeur p pour son association avec la pression diastolique. Nos recherches, pour la première fois, ont révélé que EPH/EFNs sont de nouveaux composants dans le système de régulation de la PA. Les membres de la famille EPH/EFN peuvent agir comme des forces Yin et Yang pour régler finement le tonus des vaisseaux pour assurer l'homéostasie de la PA et de sa régulation. Ces effets de EPH/EFNs dépendent du sexe et des niveaux d’hormones sexuelles. À partir de ces nouvelles connaissances, nous pourrions développer une nouvelle thérapie personnalisée pour l’hypertension artérielle, utilisant des antagonistes d'hormones sexuelles ou des thérapies de remplacement d'hormones sexuelles, selon les niveaux d'hormones sexuelles des patients et les mutations dans les gènes de l'EPH/EFN.

Extracting reusable document components for variable data printing

Variable Data Printing (VDP) has brought new flexibility and dynamism to the printed page. Each printed instance of a specific class of document can now have different degrees of customized content within the document template. This flexibility comes at a cost. If every printed page is potentially different from all others it must be rasterized separately, which is a time-consuming process. Technologies such as PPML (Personalized Print Markup Language) attempt to address this problem by dividing the bitmapped page into components that can be cached at the raster level, thereby speeding up the generation of page instances. A large number of documents are stored in Page Description Languages at a higher level of abstraction than the bitmapped page. Much of this content could be reused within a VDP environment provided that separable document components can be identified and extracted. These components then need to be individually rasterisable so that each high-level component can be related to its low-level (bitmap) equivalent. Unfortunately, the unstructured nature of most Page Description Languages makes it difficult to extract content easily. This paper outlines the problems encountered in extracting component-based content from existing page description formats, such as PostScript, PDF and SVG, and how the differences between the formats affects the ease with which content can be extracted. The techniques are illustrated with reference to a tool called COG Extractor, which extracts content from PDF and SVG and prepares it for reuse.

NGS y Metagenómica

The Next Generation Sequencing (NGS) allows to sequence the whole genome of an organism, compared to Maxam and Gilbert and Sanger sequencing that only allow to sequence, hardly, a single gene. Removing the separation of DNA fragments by electrophoresis, and the development of techniques that let the parallelization (analysing simultaneously several DNA fragments) have been crucial for the improvements of this process. The new companies in this ambit, Roche and Illumina, bet for different protocols to achieve these goals. Illumina bets for the sequencing by synthesis (SBS), requiring the library preparation and the use of adapters. Likewise, Illumina has replaced Roche because its lower rate of misincorporation, making it ideal for studies of genetic variability, transcriptomic, epigenomic, and metagenomic, in which this study will focus. However, it is noteworthy that the last progress in sequencing is carried out by the third generation sequencing, using nanotechnology to design small sequencers that sequence the whole genome of an organism quickly and inexpensively. Moreover, they provide more reliable data than current systems because they sequence a single molecule, solving the problem of synchronisation. In this way, PacBio and Nanopore allow a great progress in diagnostic and personalized medicine. Metagenomics provide to make a qualitative and quantitative analysis of the various species present in a sample. The main advantage of this technique is the no necessary isolation and growth of the species, allowing the analysis of nonculturable species. The Illumina protocol studies the variable regions of the 16S rRNA gene, which contains variable and not variables regions providing a phylogenetic classification. Therefore, metagenomics is a topic of interest to know the biodiversity of complex ecosystems and to study the microbiome of patients given the high involvement with certain microbial profiles on the condition of certain metabolic diseases.

TORP: The Open Robot Project A Framework for Module-Based Robots

The development of robots has shown itself as a very complex interdisciplinary research field. The predominant procedure for these developments in the last decades is based on the assumption that each robot is a fully personalized project, with the direct embedding of hardware and software technologies in robot parts with no level of abstraction. Although this methodology has brought countless benefits to the robotics research, on the other hand, it has imposed major drawbacks: (i) the difficulty to reuse hardware and software parts in new robots or new versions; (ii) the difficulty to compare performance of different robots parts; and (iii) the difficulty to adapt development needs-in hardware and software levels-to local groups expertise. Large advances might be reached, for example, if physical parts of a robot could be reused in a different robot constructed with other technologies by other researcher or group. This paper proposes a framework for robots, TORP (The Open Robot Project), that aims to put forward a standardization in all dimensions (electrical, mechanical and computational) of a robot shared development model. This architecture is based on the dissociation between the robot and its parts, and between the robot parts and their technologies. In this paper, the first specification for a TORP family and the first humanoid robot constructed following the TORP specification set are presented, as well as the advances proposed for their improvement.

Discovery and validation of serologic biomarkers for the diagnosis and prognosis of invasive candidiasis by computational immunomics

Invasive candidiasis (IC) is an opportunistic systemic mycosis caused by Candida species (commonly Candida albicans) that continues to pose a significant public health problem worldwide. Despite great advances in antifungal therapy and changes in clinical practices, IC remains a major infectious cause of morbidity and mortality in severely immunocompromised or critically ill patients, and further accounts for substantial healthcare costs. Its impact on patient clinical outcome and economic burden could be ameliorated by timely initiation of appropriate antifungal therapy. However, early detection of IC is extremely difficult because of its unspecific clinical signs and symptoms, and the inadequate accuracy and time delay of the currently available diagnostic or risk stratification methods. In consequence, the diagnosis of IC is often attained in advanced stages of infection (leading to delayed therapeutic interventions and ensuing poor clinical outcomes) or, unfortunately, at autopsy. In addition to the difficulties encountered in diagnosing IC at an early stage, the initial therapeutic decision-making process is also hindered by the insufficient accuracy of the currently available tools for predicting clinical outcomes in individual IC patients at presentation. Therefore, it is not surprising that clinicians are generally unable to early detect IC, and identify those IC patients who are most likely to suffer fatal clinical outcomes and may benefit from more personalized therapeutic strategies at presentation. Better diagnostic and prognostic biomarkers for IC are thus needed to improve the clinical management of this life-threatening and costly opportunistic fungal infection...
