Conceptos y aplicaciones sobre flujos densos en la hidráulica de ríos
Authors: Brea José Daniel , Spalletti Luis , Hopwood Haroldo Juan , Spalletti Pablo
Published: November 2015

Los flujos densos han sido estudiados desde diferentes disciplinas, como la geología y la hidráulica. En general, en la hidráulica fluvial se apunta a las aplicaciones prácticas en el campo de la ingeniería por lo que es necesaria la cuantificación de los procesos. Para ello, los desarrollos que parten de conocer la física del problema, analizando las fuerzas en juego, y que plantean ecuaciones que resuelven la dinámica, resultan los más adecuados. En ese contexto, han sido desarrolladas expresiones complejas que intentan incluir las variables que afectan el fenómeno a partir del comportamiento reológico de los flujos densos, y que permiten su estudio mediante modelación numérica. En la bibliografía, a partir de enfoques similares, se han desarrollado relaciones para definir los umbrales de las distintas clases de flujos hiperconcentrados. La dificultad para la determinación de los datos básicos en la aplicación de dichos desarrollos, complica el uso de estas herramientas, por lo que en la práctica ingenieril en problemas de flujos densos, en general se utilizan expresiones empíricas. A modo de ejemplo, se presentan aplicaciones en la alta cuenca del río Bermejo, en el norte argentino, en las que se analizan las características del fenómeno y la información disponible, describiéndose también las expresiones que dan los parámetros básicos a utilizar en el diseño de obras.

Authors: Olabarrieta M. , Medina Raúl , Lomónaco Tonda Pedro
Published: November 2015

En este artículo se analiza, mediante un modelo numérico, el efecto de la interacción ola-corriente en la propagación de la onda de marea en el interior de los estuarios. En concreto, se estudia la influencia de diferentes campos de oleaje incidentes en la desembocadura sobre la propagación de la onda de marea a lo largo del estuario. Los resultados obtenidos muestran que en los estuarios cuya desembocadura está sometida a la incidencia de oleaje relativamente energético, la onda de marea sufre un efecto similar a lo que produciría un aumento de la rugosidad o longitud del estuario. Más aún, aunque el oleaje se disipe totalmente en la zona más cercana a la desembocadura, sus efectos se hacen notables a lo largo de todo el estuario. Estas alteraciones en la propagación de la onda de marea tienen importantes implicaciones en la morfología de los estuarios, tanto a corto como a medio y largo plazo. Consecuentemente, modificaciones en las condiciones de oleaje en las zonas exteriores de los estuarios (construcción de diques de abrigo, espigones de canalización, etc.) conllevan variaciones en la morfología general interior de los mismos.

Abstract. The chemical link between isoprene and formaldehyde (HCHO) is a strong, non-linear function of NOx (= NO + NO2). This relationship is a linchpin for top-down isoprene emission inventory verification from orbital HCHO column observations. It is also a benchmark for overall mechanism performance with regard to VOC oxidation. Using a comprehensive suite of airborne in situ observations over the Southeast US, we quantify HCHO production across the urban-rural spectrum. Analysis of isoprene and its major first-generation oxidation products allows us to define both a "prompt" yield of HCHO (molecules of HCHO produced per molecule of freshly-emitted isoprene) and the background HCHO mixing ratio (from oxidation of longer-lived hydrocarbons). Over the range of observed NOx values (roughly 0.1–2 ppbv), the prompt yield increases by a factor of 3 (from 0.3 to 0.9 ppbv ppbv−1), while background HCHO increases by more than a factor of 2 (from 1.5 to 3.3 ppbv). We apply the same method to evaluate the performance of both a global chemical transport model (AM3) and a measurement-constrained 0-D chemical box model. Both models reproduce the NOx dependence of the prompt HCHO yield, illustrating that models with updated isoprene oxidation mechanisms can adequately capture the link between HCHO and recent isoprene emissions. On the other hand, both models under-estimate background HCHO mixing ratios, suggesting missing HCHO precursors, inadequate representation of later-generation isoprene degradation and/or under-estimated hydroxyl radical concentrations. Moreover, we find that the total organic peroxy radical production rate is essentially independent of NOx, as the increase in oxidizing capacity with NOx is largely balanced by a decrease in VOC reactivity. Thus, the observed NOx dependence of HCHO mainly reflects the changing fate of organic peroxy radicals.
Radar and satellite investigations of equatorial evening vertical drifts and spread F

Published: November 2015

Abstract. We analyzed pre-midnight equatorial F region observations made by the 30 MHz coherent backscatter radar of São Luis, Brazil between August 2010 and February 2012. These measurements were processed, and used to create monthly maps of the echo occurrence as a function of local time and height. The maps show the inter-annual variability associated with equatorial spread F (ESF) occurrence in the Brazilian longitude sector. We also constructed monthly curves of the evening vertical drifts, for the Brazilian sector, using measurements by the ion velocity meter (IVM) onboard the C/NOFS satellite. The IVM evening drifts show a good overall agreement with the Scherliess and Fejer (1999) empirical model. Measured and model drifts show the development of the pre-reversal enhancement (PRE) of the vertical plasma drifts during ESF season. Using joint radar and satellite measurements, we found that evening (18:00–18:30 LT) mean non-negative drifts provide a necessary but not sufficient condition for the occurrence of topside ESF echoes. Evening downward (negative) drifts preceded the absence of topside ESF irregularities.

Abstract. Coupled ice sheet-ocean models capable of simulating moving grounding lines are just becoming available. Such models have a broad range of potential applications in studying the dynamics of marine ice sheets and tidewater glaciers, from process studies to future projections of ice mass loss and sea level rise. The Marine Ice Sheet-Ocean Model Intercomparison Project (MISOMIP) is a community effort aimed at designing and coordinating a series of model intercomparison projects (MIPs) for model evaluation in idealized setups, model verification based on observations, and future projections for key regions in the West Antarctic Ice Sheet (WAIS). Here we describe computational experiments constituting three interrelated MIPs for marine ice sheet models and regional ocean circulation models incorporating ice shelf cavities. These consist of ice sheet experiments under the Marine Ice Sheet MIP third phase (MISMIP+), ocean experiments under the ice shelf-ocean MIP second phase (ISOMIP+) and coupled ice sheet-ocean experiments under the MISOMIP first phase (MISOMIP1). All three MIPs use a shared domain with idealized bedrock topography and forcing, allowing the coupled simulations (MISOMIP1) to be compared directly to the individual component simulations (MISMIP+ and ISOMIP+). The experiments, which have qualitative similarities to Pine Island Glacier Ice Shelf and the adjacent region of the Amundsen Sea, are designed to explore the effects of changes in ocean conditions, specifically the temperature at depth, on basal melting and ice dynamics. In future work, differences between model results will form the basis for evaluation of the participating models.

Abstract. Our current knowledge of broad-scale patterns of primary production in the Southern Ocean is derived from satellite ocean-colour estimates of chlorophyll a (Chl a) in the open ocean, typically in spring-summer. Here, we provide evidence that large-scale intra-ice phytoplankton surface aggregation occur off the coast of Antarctica during austral autumn, and that these "blooms" are largely undetected in satellite ocean-colour time series (which mask the ice-covered ocean). We present an analysis of (i) true-colour (visible) satellite imagery in combination with (ii) conventional ocean-colour data, and (iii) direct sampling from a research vessel, to identify and characterise a large-scale intra-ice algal occurrence off the coast of East Antarctica in early autumn (March) 2012. We also present evidence of these autumn "blooms" in other regions (for example, Princess Astrid Coast in 2012) and other years (for example, Terra Nova Bay in 2015) implying regular and widespread occurrence of these phenomena. The occurrence of such undetected algal accumulations implies that the magnitude of primary production in the Southern Ocean is currently underestimated.
Deconstrucción de los relatos evangélicos de la pasión. Sobre el arraigo de la ficción en la Historia de las religiones
Authors: Bermejo Fernando
Published: November 2015

Las más elementales exigencias de rigor crítico e independencia siguen a menudo sin cumplirse hoy en día en la reconstrucción histórica de la figura del judío Yeshua ben Yosef (Jesús el galileo), en parte porque el carácter inconsistente de las fuentes evangélicas no es tomado en serio. El presente artículo analiza las incongruencias de los relatos de la pasión, muestra en ellos los indicios de un proceso de despolitización, y señala el carácter insostenible de varias afirmaciones clave de muchos historiadores contemporáneos sobre el predicador galileo.

Tourism Development in the Dutch Wadden Area: Spatial-Temporal Characteristics and Monitoring Needs
Authors: Sijtsma Frans J. , Broersma Lourens , Daams Michiel N. , Hoekstra Hendrik , Werner Gelijn
Published: November 2015

The paper presents a spatial and temporal analysis of tourism in the Dutch Wadden area and identifies policy dilemmas and monitoring needs. The analysis is temporal because historical, current and future aspects of tourism development are addressed; it is spatial because the spatial differentiaton of tourism within the Wadden area is examined. For the assessment of the historical and current situation focus is on visitor and employment data and especially the relative degree of specialization of the local economy on tourism. For the future direction of tourism and possible investment options, the paper draws on surveyed views of 91 tourism entrepreneurs in the Wadden area. On the basis of this spatial and temporal analysis, the paper identifies policy dilemmas that differ substantially among the Wadden islands, the Waddensea, and the mainland Wadden coast. Drawing on this in depth empirical analysis the paper theoretically aims to enrich the Tourism Area Life Cycle (TALC) concept and the monitoring it implies. In response to the needs of monitoring sustainablilty, the paper argues for a broader yet still minimal extension of TALC. It argues for a four quadrant TALC – named TALC-4q – in which four perspectives on tourism development are combined: market, ecology and nature, regional labor market and policy. The combination of monitoring visitor flows and market share, together with ecological quality, employment size and share, and the consensus on policy, is expected to refine the accuracy of the TALC concept and fuel its wider use in the search for sustainable tourism. 
Being a good spy: Legitimizing access to web-based observation
Authors: Grønning Ingeborg
Published: November 2015

Observation of online forums is a relevant methodological approach for researchers in several disciplines. However, ethical guidelines on such observations challenge the ethically concerned researcher. In this paper, I reflect on how I carried out my observation of an online weight-loss forum, and how I could have conducted it differently to meet ethical standards and the demands of high-quality research. After receiving approval from the forum administrators to observe the forum, information about my project on obesity was posted online. Some of the participants reacted negatively to my presence in the forum. This paper draws on the evolving discussion between researcher and participants on the complex issue of research ethics, particularly informed consent, in studying closed forums on the Internet. It is suggested that evaluating whether participants are harmed is more important than the public/private divide when considering whether informed consent is necessary.
Ethics and collective identity building: Scandinavian semicommunication and the possibilities of Philippine ethics
Authors: Lasquety-Reyes Jeremiah , Alvarez Allen
Published: November 2015

How should national societies build legitimate and inclusive collective identities amidst prolific multiculturalism and linguistic diversity? We argue that cultural ownership of particular ways of framing ethics should be part of this collective identity building process. We should avoid unfair domination of minority cultural identities, but how do we do this when ethical discourses themselves tend to be shaped by particular dominant identities? We look into the case of the challenges that a particular multicultural society, the Philippines, faces in its ongoing collective identity building project on three levels: (1) ethnic and linguistic differences (e.g. differences between Tagalog, Cebuano, Maranao, etc.), (2) the historical layers of foreign culture (e.g. Islamic, Spanish, and American) that have each influenced these distinct cultural identities in different degrees, and (3) the apparent domination of Tagalog linguistic culture over others. Our answer to the question of legitimate and inclusive collective identity comes from an inter-linguistic dialogue that can be effected between cultures by harnessing similarities of ethical concepts, without compromising cultural differences. We present three different possible approaches under the following headings: (1) Pilipino ethics, (2) Filipino ethics and (3) Philippine ethics, each representing a particular stance to the dominant Tagalog linguistic culture. We argue for the third option, which is the most inclusive because of how it equalizes the status of all participating cultures in the dialogue. We also draw from the possibilities afforded by the phenomena of Scandinavian semicommunication (Haugen 1966) and what this practice offers in making collective identity building more inclusive.
Å leve et menneskeverdig liv - Martha Nussbaums globale helseetikk
Authors: Lysaker Odin
Published: November 2015

Nylig igangsatte FN Post-2015, sin nye utviklingsagenda. Sentralt er en global kamp for bedret helse, hvor det å leve et menneskeverdig liv står i sentrum. Imidlertid er forståelsen av selve helsebegrepet omstridt. Noen mener at det bør knyttes an til jus og menneskerettigheter, mens andre foreslår etikk og menneskeverd. Dette hviler i sin tur på motstridende menneskesyn i den globale helseetiske diskursen, nemlig mennesket som enten autonomt eller avhengig. I artikkelen analyserer jeg denne debatten ut fra det jeg hevder er Martha Nussbaums globale helseetikk, som baseres på hennes kapabilitetstilnærming så vel som begrep om ‘helse som livskvalitet’. Min konklusjon er at Nussbaums normative begrunnelse for Post-2015 ut fra et kroppslig forankret menneskeverd er det mest overbevisende av de to konkurrerende svarene.Nøkkelord: global helseetikk, Martha Nussbaum, menneskeverd, menneskerettigheter, post-2015English summary: Living a dignified life - Martha Nussbaum's global health ethicsThe UN recently launched Post-2015, which is its new development agenda. Central here is the global struggle for improved health, in which what it takes to live a dignified life is stressed. However, the understanding of the notion of health is disputed. Some believe that it should be linked to law and the human rights, while others suggest ethics and human dignity. Which in turn rests on conflicting stands in the global health ethical discourse regards to the view of humanity, namely either as autonomous or dependent. In the paper I analyse this discourse, in which my point of departure is Martha Nussbaum’s capabilities approach as well as her concept of health as life quality. This I read exactly as a global health ethics. Thus, I conclude that between the two competing answers, Nussbaum’s normative justification for Post-2015 on the basis of bodily grounded human dignity is the most convincing.Keywords: global health ethics, Martha Nussbaum, human dignity, human rights, Post-2015
Understanding Identity Making in the Context of Sociopolitical Involvement among Asian and Pacific Islander American Lesbian and Bisexual Women
Authors: Battle Juan , Harris Angelique , Donaldson Vernisa , Mushtaq Omar
Published: November 2015

This study examines how Asian and Pacific Islander American (API) lesbians and bisexual women form identities within the context of occupying both ethnic and sexual minority social statuses. To do so, we examine the correlates of sociopolitical involvement within minority communities among a sample of 175 API lesbian and bisexual women. The findings suggest that feeling connected to lesbian, gay, bisexual, and transgender (LGBT) communities plays the most influential role in their sociopolitical involvement within both LGBT and people of color (POC) communities, while comfort in racial communities plays a negative role on LGBT sociopolitical involvement but has no impact on POC sociopolitical involvement. We then discuss implications for identity formation.
4G/4G PAI-1 gene variant in a patient with non-healing ulcers
Authors: Peluso Heather , Caffrey Julie A. , Milner Stephen M.
Published: November 2015

Plasminogen activator inhibitor is a serine protease inhibitor from the serpin gene family that modulates fibrin clot breakdown.PAI-1 irreversibly inhibits tissue plasminogen activator (t-PA) and urokinase plasminogen activator (u-PA) from activatingplasminogen. PAI-1 also inhibits integrin-vitronectin and vitronectin-vitronectin interactions that are essential for cell migration,adhesion, and angiogenesis. We describe a patient, who developed chronic non-healing ulcers after minimal trauma to severalareas of his body. Genetic testing revealed the 4G/4G homozygous genotype for the polymorphism in the promoter regionof the PAI-1 gene. Increased PAI-1 activity prevents the breakdown of the fibrin clot and cell migration to remodel damagedtissue. A combination of poor clot fibrinolysis and cell recruitment to the site of injury may explain our patient’s non-healingulcers following minor traumatic injury. Early treatment with excision and skin grafting may benefit patients presenting withnon-healing ulcers and the homozygous 4G/4G PAI-1 variant. To our knowledge, there have been no reports in the literatureassociating PAI-1 overexpression and chronic non-healing wounds.
Notes on the representational possibilities of projective quadrics in four dimensions
Authors: Bácsó Sándor , Szilasi Zoltán
Published: November 2015

The paper deals with hyper-quadrics in the real projective 4-space. According to [1] there exist 11 types of hypersurfaces of 2nd order, which can be represented by 'projective normal forms' with respect to a polar simplex as coordinate frame. By interpreting this frame as a Cartesian frame in the (projectively extended) Euclidean 4-space one will receive sort of Euclidean standard types of hyper-quadrics resp., hypersurfaces of 2nd order: the sphere as representative of hyper-ellipsoids, equilateral hyper-hyperboloids, and hyper-cones of revolution. It seems to be worthwhile to visualize the "typical" projective hyper-quadrics by means of descriptive geometry in the (projectively extended) Euclidean 4-space using Maurin's method [4] or the classical (skew) axonometric mapping of that 4-space into an image plane.
On four-dimensional crystallographic groups
Authors: Horváth Eszter
Published: November 2015

In his paper [12] S. S. Ryshkov gave the group of integral automorphisms of some quadratic forms (according to Dade [6]). These groups can be considered as maximal point groups of some four-dimensional translation lattices in E^4. The maximal reflection group of each point group, its fundamental domain, then the reflection group in the whole symmetry group of the lattice and its fundamental domain will be discussed. This program will be carried out first on group T. G. Maxwell [9] raised the question whether group T was a reflection group. He conjectured that it was not. We proved that he had been right. We shall answer this question for other groups as well. Finally we shall give the location of the considered groups in the tables of monograph [4]. We hope that our elementary method will be useful in studying linear algebra and analytic geometry. Futhermore, 4-dimensional geometry with some visualisation helps in better understanding important concepts in higher-dimensional mathematics, in general.
New style in teaching word processing
Authors: Arató Mátyás , Bujdosó Gyöngyi
Published: November 2015

Teaching word processing is confined to looking through some menus and showing some functions of a word processor program, although technology presents just a small part of forming layouts. This fact causes that people who are writing documents spend a lot of time by trying to form, e.g., title pages or inner pages.
The present paper deals with a design of an online course on word processing that fits better the needs of many users. The online course is designed for teaching (LA)TEX by leading the students to the technical issues of the typesetting system through layout and grammar rules: demonstrates the most important basic recommendations of typography and grammar rules through samples, and shows how to program the currently displayed layout in the (LA)TEX programming languages. This methodology suits better the common working habit, and can be a useful help in word processing documents.

Typical mistakes in Mental Cutting Test and their consequences in gender differences
Authors: Németh Brigitta , Sörös Csilla , Hoffmann Miklós
Published: November 2015

Spatial ability of first year university students is measured and evaluated in this paper. We used standard Mental Cutting Test (MCT), where a body is given by perspective view and correct cross section has to be chosen. While gender differences in MCT are reported by several papers including our earlier results, much less known are the reasons of these differences. Here we show that typical mistakes (answers to problems which are close to be correct) can be one of the possible reasons, since female students made typical mistakes in some cases more frequently than males.

Human Identification by Gait Using Time Delay Neural Networks
Authors: Mashagba Eman
Published: November 2015

This paper proposed human identification method by gait. Human gait is a type of biometric features and related to the physiological and behavioral features of a human. In this paper, a feature vector of gait motion parameters is extracted from each frame using image segmentation methods, and categorized into different categories. Two of these categories were used to form the gait motion trajectories; Category one: Gait angle velocity: angle velocity hip, angle velocity knee, angle velocity thigh and angle velocity shank. Category two: Gait angle acceleration: angle acceleration hip, angle acceleration knee, angle acceleration thigh and angle acceleration shank for each image sequence. Finally, the TDNN method with different training algorithms is used for recognition purpose. This experiment is done on our own database. This research  developed a method which  achieves a higher  recognition rate in the training set 100% and in the testing set 83%. Also, category one  establishes gait motion features to be used in human gait identification applications using different training algorithms, While category two achieved a higher recognition rate by trainrb algorithm.
Improved Recommender for Location Privacy Preferences
Authors: A. Hadi Anas , Cazalas Jonathan
Published: November 2015

Location-based services are one of the fastest growing technologies. Millions of users are using these services and sharing their locations using their smart devices. The popularity of using such applications, while enabling others to access user’s location, brings with it many privacy issues. The user has the ability to set his location privacy preferences manually. Many users face difficulties in order to set their preferences in the proper way. One solution is to use machine learning based methods to predict location privacy preferences automatically. These models suffer from degraded performance when there is no sufficient training data. Another solution is to make the decision for the intended user, depending on the collected opinions from similar users. User-User Collaborative Filtering (CF) is an example within this category. In this paper, we will introduce an improved machine learning based predictor. The results show significant improvements in the performance. The accuracy was improved from 75.30% up to 84.82%, while the privacy leak was reduced from 11.75% up to 7.65%. We also introduced an integrated model which combines both machine learning based methods and collaborative filtering based methods in order to get the advantages from both of them.
Trusted Base Stations-Based Privacy Preserving Technique in Location-Based Services
Authors: Aqib Muhammad , Cazalas Jonathan
Published: November 2015

With the advent in mobile and internet technologies, there is a significant increase in the number of users using smartphones and other internet based applications. There are a large number of applications available online that use the internet and provide useful information to the users. These include ones that provide location-based services e.g. google maps etc. These applications provide many facilities to the users who want information regarding a specific area or directions using an optimal path to a destination. Due to these reasons, the number of clients using these applications is increasing on a daily basis. Although these services are very useful and are making it easy for us to get information about our surroundings, some issues are also linked with the use of these applications and their services. One of the more significant issues of using these services is privacy with respect to sending personal location information to location-based services servers. Researchers have provided many solutions to solve these issues. One of the solutions is through caching and use of k-anonymity techniques. In this paper, we have proposed a method to solve the privacy issue that uses caching data approach to reduce the number of queries sent to the location-based services server. We also discuss the use of the concept of k-anonymity when no relevant data is available in cache, and queries are sent to the server.
Influence of Chitosan-Alginate Microcapsules Containing Anti-Vibrio Harveyi IgY in the Gastrointestinal Tract Simulation
Authors: Punyokun Kawin , Hongprayoon Ratchanee , Srisapoome Prapansak , Sirinarumitre Theerapol
Published: November 2015

Egg yolk immunoglobulin (IgY) is an alternative treatment for the prevention of gastrointestinal infections in pigs, cows, chickens and fish. In our previous report, we preliminarily proved that anti-V. harveyi IgY had effective potential to control luminous disease in black tiger shrimp. However,IgY activity may be reduced or destroyed by gastric conditions, particularly low pH and digestive enzymes. Therefore, it is necessary to find an effective method to preserve the therapeutic function of IgY antibodies during gastric passage. Chitosan-alginate microcapsules have been developed to protect IgY from gastric inactivation. The processing factors included different forms of chitosan and alginate, while a CaCl2 concentration and encapsulation medium was investigated. The optimum results were obtained under the following conditions: High Mw chitosan concentration 0.2% (w/v), medium viscosity alginate concentration 2% (w/v), CaCl2 concentration 0.5% (w/v). The stability of IgY in simulated gastric fluid (SGF, pH 1.2) was greatly improved by encapsulation in chitosan-alginate microcapsules, and retained greater than 90% activity after 2 h exposure to SGF. Less than 10% IgY was released upon the microcapsules’ exposure to SGF for 2 h, and more than 80% IgY was released upon the microcapsules’ exposure to simulated intestinal fluid (SIF, pH 6.8) for 16 h. 
Application of Social Network Analysis for Analyzing the Relationships between Root and Direct Causes of Defects
Authors: Brink Chantelle Van Den , Han Sangwon
Published: November 2015

This paper addresses the application of social network analysis (SNA) in understanding and representing the relationships between the root and direct causes of defects. The root and direct causes of construction defects were identified through extensive literature review, and the thoroughness of the identified causes was confirmed by examining 91 non-conformance reports. The SNA software UCINET was used to visually map the links between the direct and root causes for identifying the root causes that accounted for the majority of direct causes and defects. A measure of centrality and adjacency indicated that the root cause Constructor Error/Omission was directly linked to seven of the ten identified direct causes. It was also determined that eliminating this root cause together with Transportation Error would reduce the number of defects by 90%. Since the root causes responsible for the majority of direct causes as well as the largest number of defects could be identified using SNA, it is concluded that SNA is a valuable tool for recognizing where resources should be employed for the elimination of defects.

Published: November 2015

There is a relation between Emotional intelligence, knowledge management and culture of each organization. In this research the impact of organizational cultures have been studied. The methodology has been used for this research was descriptive. According to type and size of their projects, organizational culture was estimated as bureaucratic in seven organizations. The Quinn organizational culture questionnaire along with several interviews with managers verified the bureaucratic culture in four organizations. The applied tool for data collection was a questionnaire consisting of 33 questions. Moreover, the sample size was 344 employees in four organizations. To investigate the reliability of the questionnaire the Cronbach’s alpha value has been measured and the validity has been confirmed by the field. Moreover, according to Goleman’s emotional intelligence model the five factors have been measured in the selected organizations. Also the knowledge management‘s Model presented by Nonaka and Takeuchi has been used by considering four presented elements.

The results demonstrated that in the bureaucratic cultures, externalization and combination are in a proper status. Analyzing the research data depicted the relationship between different dimensions of emotional intelligence and the ability of individuals in different aspects of converting the knowledge. For example Social skill and empathy ability of individuals have a positive and significant relationship with socialization. 
Necessity of Clinical Engineers to Improve Present Health Technology Management in Developing Countries

Published: November 2015

Developing countries such as Bangladesh, Nepal, Bhutan, Indonesia and so many could not introduce clinical engineering professional (CEP) in health technology management (HTM) science. As a result, they could not establish the safe health technology management. Conversely, CEP has been introduced by developed countries in HTM for about last 35 years long and thereby established a safe health care system. We noticed the continual problem in the health care management system. To overcome this continual problem, we think that clinical engineering professional is very much necessary to proper implementation of health technology management in developing countries in order to ensure the safe health care system. CEP will train to HTM personnel and a safe health care management will be established in developing countries. The modern medical technology will be involved by the proper practice of HTM and CEP. This pioneer professional will keep the whole HTM with good functional condition. Therefore, we conclude that introducing of CEP is badly necessary to improve the existing unhealthy HTM as well as health care system of the developing countries.HTM personnel will understand the necessity of CEP as well as health care planners. This paper will guide to the existing personnel of HTM and help them to understand the importance roles of CEP. Among these counties, the health care technology management system seems to very problematic. Continually, it is observing that the health care technology management performance is twisting with the increase of sophisticated medical devices. Authors firmly believe that an excellent benefit can be obtained by introducing skilled clinical engineers in the health services of developing countries as Bangladesh. 
Transmigrant Farmers Adaptation to Rainfed Rice Field and Irrigated Rice Field in North Luwu Regency, South Sulawesi - Indonesia
Authors: Meiyani Eliza
Published: November 2015

This research is aimed to study the anthropology of transmigration, particularly on transmigrants' adaptation to different cultural background and environment of their new place. There are three analyzed variables in this research: the farmers' basic ability, culture (tradition), and motivation which might closely related to their adaptation capability in a new location. This is a quantitative research and it was conducted in Malangke District, North Luwu Regency, South Sulawesi. Multi-stage cluster random sampling was used as the sampling method. There were 400 samples taken in this study which consist of 200 farmers of rainfed ricefield and 200 farmers of irrigated rice field. The data was taken by conducting several interviews which are based on a question list and observation. Then the data was analyzed using factor (main component) analysis, path analysis, and product-moment correlation analysis. The result shows that transmigrants' adaptation capability is not influenced only by the new physical environment condition where they live, but also their origin as well as the social, economic, and cultural factors that become parts of their life.

A gamificação vem sendo bastante utilizada no ensino como ferramenta de apoio e motivação através de mecânicas de jogos. Por ser um área de pesquisa recente, mas que vem apresentando resultados ao longo dos anos junto a comunidade brasileira de informática na educação é necessário analisar e consolidar suas contribuições de modo a caracterizá-las. Este trabalho busca investigar e entender melhor como gamificação contribui no processo ensino-aprendizagem bem como identificar em que medida é aplicado a este campo. Assim, este artigo apresenta um mapeamento sistemático do uso de gamificação em softwares educativos no contexto das pesquisas brasileiras apresentadas em eventos nacionais.
How should laboratories measure mycobacterial load?
Authors: Theron Grant
Published: November 2015

The ability to accurately and reproducibly quantify mycobacteria in a cost-effective manner is essential for both basic and applied tuberculosis (TB) research. In immunology, laboratory-based experiments are frequently performed to compare the effect of regulatory T-cells on mycobacterial kill under different conditions
A comparison of cost for mycobacterial load determination in research laboratories

Background. Mycobacterial load determination is a critical quantitative measure needed in many clinical and research laboratory studies and selection depends on several factors including sensitivity, dynamic range and turnaround time. However, there are no data about cost, which is an important selection determinant. We therefore performed a cost analysis of five quantitative mycobacterial load assays.

Methods. The costs of five mycobacterial quantification techniques were compared in a hypothetical single experiment (control and intervention) performed in triplicate. Assays evaluated were: mycobacterial colony-forming units (MCFU) using 7H10-Middlebrook solid media, automated liquid culture (BACTEC-MGIT-960), [3H]-uracil incorporation assays, luciferase-reporter construct bioluminescence, and quantitative polymerase chain reaction (PCR) (Xpert-MTB/RIF) using serial dilutions of Mycobacterium tuberculosis. Costs associated with consumables, equipment and personnel were included and expressed in 2015 South African rands and US dollars.

Results. The least costly technique was the luminescence reporter construct assay (R85.68/$6.72) whereas the most expensive technique was the Xpert MTB/RIF PCR (R388.02/$30.42). The high cost of the PCR assay was mainly attributable to the costly Xpert MTB/RIF cartridges. Although the MCFU by solid culture had a similar cost compared with uracil incorporation and Xpert MTB/RIF, the purchase price of the equipment required to perform the latter assays was ~2 - 10 times higher.

Conclusion. Taking into consideration the turnaround time, capital costs, discriminatory ability, the running costs (excluding staff) of the luminescence reporter assay are the lowest. Where time to result is critical, more expensive techniques such as the Xpert MTB/RIF should be used. In a clinical setting where automated culture and Xpert are routinely performed, quantitative load from time to positivity and cycle thresholds will provide extra data without additional cost.
Hypersensitivity pneumonitis
Authors: Khalfey H
Published: November 2015

Hypersensitivity pneumonitis (HP) refers to the inflammatory lung condition that arises from inhalational exposure to various (mostly organic) antigens with the development of lymphocytic alveolitis and granulomatous pneumonitis. A myriad of antigens have been implicated and the list continues to grow. The clinical features are varied, implicated antigens protean, and the investigations complementary in making a diagnosis, but the condition remains a difficult one to diagnose, mostly due to a lack of clinical suspicion. In this article we discuss HP, its aetiology, clinical features as well as diagnosis and management.

Published: November 2015

Background. Obstructive sleep apnoea syndrome (OSAS) is associated with increased morbidity and mortality. However, there are few studies from Nigeria that have evaluated the prevalence of OSAS in medical outpatient clinics.

Objective. To determine the degree of the risk of OSAS among patients attending the medical outpatient clinic of the Federal Medical Centre, Owo, South-West Nigeria.

Methods. A cross-sectional survey was conducted among 208 medical outpatients using the Berlin questionnaire and the Epworth sleepiness scale (ESS).

Results. The mean (standard deviation) age of participants was 53.8 (16.5) years, 110 (52.9%) were female, and 73.1% of participants had a high likelihood of sleep-disordered breathing (HSDB). Subjects with a high body mass index (BMI) were more likely to have sleep -disordered breathing when compared with those with a normal BMI (26 (96.3%) v. 7 (29.2%), p<0.001). The respondents with multiple primary morbidities were about 24 times more likely to have HSDB compared with respondents with a single morbidity (p=0.009). The odds of having HSDB was 16 times greater in those with hypertension compared with patients with asthma (odds ratio 16, 95% confidence interval 3 - 83, p=0.001). The Berlin questionnaire and the ESS were useful screening tools in the Nigerian setting.

Conclusion. In resource-poor settings in Africa, where there is an emphasis on screening and treating diseases of poverty, patients with medical conditions such as high BMI and hypertension should be screened for OSAS.
Du regard en soi au regard de l’autre
Authors: Gendron-Langevin Maud
Published: November 2015

Cet article propose une analyse réflexive sur un projet d’ethno-théâtre thérapie en milieu scolaire avec des élèves en difficulté d’adaptation. La notion de regards superposés est explorée sous trois angles : en groupe de thérapie, en représentation théâtrale et en différé via un documentaire. Le témoin actif est défini en tenant compte des risques et du potentiel relatifs au processus thérapeutique. La notion de regard en groupe de dramathérapie et en classe d’art dramatique est mise en perspective afin d’ouvrir sur un possible échange entre ces disciplines qui utilisent toutes deux les outils du théâtre et de l’art dramatique à des fins différentes.
Le surtitrage intralingual au théâtre… ou son absence : une étude de cas des Belles-Soeurs à Paris
Authors: Laliberté Michèle
Published: November 2015

Cet article fait le point sur l’évolution du débat linguistique entourant la présentation des Belles-Soeurs en France, en faisant l’analyse de l’interdiscours sur le joual relevé dans les dossiers de presse de 2012 et en le comparant aux propos des journalistes qui avaient vu la pièce de Tremblay à Paris en 1973. Le second volet de cette étude est une réflexion sur la pertinence du surtitrage lorsqu’il s’agit de présenter une pièce de théâtre dont la langue de départ est bien celle du public cible, mais dont la variante diatopique pose un problème de compréhension pour l’auditoire. L’analyse de l’interdiscours sur le joual révèle que le débat est empreint d’émotion et que cette composante affective, sous-jacente au discours des différents intervenants, pourrait avoir influencé les propos des journalistes de la presse écrite. L’auteure conclut qu’il serait intéressant de rendre au surtitrage intralingual ses lettres de noblesse en considérant toutes les avenues qu’il serait en mesure de créer pour la représentation théâtrale, et cela sur les plans dramaturgique, esthétique et interculturel.
