Influencia del estilo de vida, el sexo, la edad y el IMC sobre la salud física y psicológica en jóvenes universitarios
Authors: Angelucci Luisa Teresa , Cañoto Yolanda , Hernández María Jimena
Published: September 2017

Los posibles cambios en los estilos de vida que se producen al ingresar en la universidad, en conjunto con otros factores, impactan la salud, tanto física como mental de los jóvenes y, por lo tanto, su desempeño académico y social; siendo necesario entonces, analizar la relación estilos de vida-salud en esta población. Así, el objetivo de la investigación fue determinar la influencia del estilo de vida, el sexo, la edad y el índice de masa corporal sobre la salud física y psicológica de jóvenes universitarios, mediante una investigación explicativa con un diseño prospectivo único. Se usó una Escala de Estilos de Vida, un Cuestionario de Salud General (GHQ-28), una Escala de Salud física y una hoja de identificación. Se evidenció que los 312 universitarios de la muestra, en general, gozan de buena salud. Reportan dificultades del sueño, gripe, dolor de huesos y cabeza. Presentan niveles bajos de depresión y malestar psicológico, con niveles moderados-bajos de ansiedad. Manifiestan hábitos inadecuados en alimentación, actividad física y chequeos médicos y, el consumo de drogas es bajo. Por medio de una regresión múltiple, se obtuvo que a mayor inadecuados hábitos de sueño y frecuencia de chequeos médicos mayores síntomas físicos. Mayor ansiedad se encuentra en mujeres, jóvenes con problemas de sueño y personas que consumen drogas. A menor edad y mayores problemas de sueño mayor depresión. El malestar psicológico  se presenta con menor actividad física y problemas de sueño. Los resultados sugieren la conveniencia de crear programas de prevención en la universidad, tomando en cuenta los estilos de vida de los jóvenes

Authors: Alves Joatã Soares Coelho , Bendassolli Pedro Fernando , Gondim Sônia Maria Guedes
Published: September 2017

El objetivo de esta investigación fue verificar el papel predictor del trabajo emocional en la incidencia del burnout en policías militares. Participaron 525 militares profesionales: 408 hombres y 117 mujeres. Tres escalas adaptadas para portugués fueron usadas en el estudio: Emotional Labour Scale, Emotion Work Requirements Scale y la subescala de agotamiento emocional de Maslach Burnout Inventory. Análisis de regresión múltiple fueron realizados para evaluar el poder predictivo de las dimensiones de trabajo emocional y de variables sociodemográficas sobre el burnout. Los resultados indican que todas las dimensiones de trabajo emocional se mostraron como predictores de burnout: variedad e intensidad de las emociones, frecuencia de interacción con sospechosos y criminales, regulación profunda y regulación superficial, y la necesidad de expresar emociones positivas como parte del trabajo policial. Haber completado la escuela secundaria, ser Cabo y actuar en el servicio extremo también fueron predictores de burnout. Las evidencias del impacto del trabajo emocional y del cargo en la incidencia de burnout ponen en evidencia la importancia de dar atención especial a la salud y al desarrollo de competencias socioemocionales de policías militares

Published: September 2017

Se tuvo como objetivo comparar el perfil comportamental de niños con enfermedades crónicas de la piel (dermatitis atópica, psioriasis y vitiligo). Fue realizado un estudio transversal con un muestreo por conveniencia. Participaron 26 madres, con hijos entre 6 y 12 años y diagnósticos de enfermedades crónicas de la piel. Los instrumentos utilizados fueron el Child Behavior Checklist for ages 4/18 (cbcl 4/18) y el formulario sociodemográfico. Se realizó una comparación entre grupos de niños con diferentes enfermedades crónicas de piel en cuanto a las competencias sociales y problemas de comportamiento, por medio de la prueba no paramétrica de Kruskal-Walis (p < 0,05). Los resultados indicaron diferencias estadísticamente significativas entre los tres grupos en cuanto a la competencia global, social, escolar y para actividades. Niños con dermatitis atópica presentaron menor competencia para actividades y niños con vitiligo para competencia social. Los tres grupos presentaron baja frecuencia de niños con perfil clínico para competencia escolar y alta frecuencia de niños clasificados como clínicas para problemas de comportamiento. Se discute el papel de las dermatosis crónicas en el desarrollo de problemas de comportamiento y competencias sociales.

Validação da versão portuguesa da Escala de Motivação Situacional (sims) em contextos académicos
Authors: Paixão Olímpio , Gamboa Vítor , Valadas Sandra
Published: September 2017

La Escala de Motivación Situacional (sims) busca evaluar la motivación experimentada en el desempeño de una tarea específica. El objetivo de esta investigación fue el de validar la versión portuguesa, con una muestra de 409 estudiantes, al intentar reproducir su estructura factorial. Los resultados demuestran una consistencia interna adecuada respecto a las subescalas. La validez del constructo fue evaluado con Análisis Factorial Confirmatorio. Los valores de contribución de cada factor y los índices de ajuste señalan la necesidad de eliminar de dos ítems, que, por su turno, van de encuentro a resultados de otros estudios de validación. En general, los resultados indican que la sims está compuesta por cuatro factores consistentes y demuestran su calidad psicométrica. La escala parece ser una buena medida de autorrelato para evaluar la motivación intrínseca, regulación identificada, regulación externa, y desmotivación situacional, pudiendo ser utilizada en la evaluación del constructo en el contexto académico portugués
La comprensión simbólica de imágenes digitales que representan acciones dirigidas hacia un fin
Authors: Jauck Daniela Eva , Peralta Olga Alicia
Published: September 2017

Los dispositivos digitales están cada vez más presentes en la vida cotidiana y han comenzado a utilizarse en la comunicación y el aprendizaje a edades muy tempranas. Aunque padres y educadores suponen que los pequeños comprenden la función simbólica de sus imágenes, la incipiente pero creciente investigación en el área no ha arrojado resultados claros al respecto. El objetivo del presente estudio fue indagar si los niños pequeños comprenden que las imágenes provistas por una tablet representan acciones que pueden ocurrir en la realidad. Presentamos a niños de 24, 30 y 36 meses de edad imágenes de acciones cotidianas en secuencias que no mostraban el resultado de la acción. Luego, los niños debían escoger un objeto real que ostentaba el resultado de la acción. Encontramos que a los 30 y 36 meses, pero no a los 24, los niños comprenden que las imágenes representan una acción que puede ocurrir en la realidad. Los resultados se discuten en torno a la comprensión simbólica de imágenes y a la comprensión de acciones intencionales cuyo fin los niños deben imaginar.
Searching, Shaping, and the Quest for Superior Performance
Authors: Gavetti Giovanni , Helfat Constance E. , Marengo Luigi
Published: September 2017

This article has three premises. First, much strategy work has tended to focus more on search than shaping the business context. Second, prior research has yet to precisely define and elucidate conceptually what it means to shape the business context. We argue that shaping entails creating or changing the payoff structure—the mapping between the choices that firms make and the payoffs to them—for all firms in a particular business context. Third, research has paid limited attention to the interdependencies between search and shaping, and to what we call the “paradox of shaping.” That is, firms face the paradox that although they can improve their performance by shaping the business context or landscape, the more often other firms reshape the landscape and the more elements of the landscape that other firms alter, the less sustainable are any competitive advantages derived from shaping. Taken together, these premises highlight an important gap–that most theories and formal models of firm performance, strategic opportunities, and competitive advantage, miss an important component of the profitability equation—and addressing it is precisely what this article aspires to do.

Management of syndesmotic injuries of the ankle
Authors: de-las-Heras Romero Jorge , Alvarez Ana María Lledó , Sanchez Fernando Moreno , Garcia Alejandro Perez , Porcel Pedro Antonio Garcia , Sarabia Raul Valverde , Torralba Marina Hernandez
Published: September 2017

Injuries to the tibioperoneal syndesmosis are more frequent than previously thought and their treatment is essential for the stability of the ankle mortise. Recognition of these lesions is essential to avoid long-term morbidity. Diagnosis often requires complete history, physical examination, weight-bearing radiographs and MRI. Treatment-oriented classification is mandatory. It is recommended that acute stable injuries are treated conservatively and unstable injuries surgically by syndesmotic screw fixation, suture-button dynamic fixation or direct repair of the anterior inferior tibiofibular ligament. Subacute injuries may require ligamentoplasty and chronic lesions are best treated by syndesmotic fusion. However, knowledge about syndesmotic injuries is still limited as recommendations for surgical treatment are only based on level IV and V evidence.

Rapid, Secure Drug Testing Using Fingerprint Development and Paper Spray Mass Spectrometry
Authors: Costa Catia , Webb Roger , Palitsin Vladimir , Ismail Mahado , de Puit Marcel , Atkinson Samuel , Bailey Melanie J
Published: September 2017

BACKGROUND

Paper spray mass spectrometry (PS-MS) is a technique that has recently emerged and has shown excellent analytical sensitivity to a number of drugs in blood. As an alternative to blood, fingerprints have been shown to provide a noninvasive and traceable sampling matrix. Our goal was to validate the use of fingerprint samples to detect cocaine use.

METHODS

Samples were collected on triangular pieces (168 mm2) of washed Whatman Grade I chromatography paper. Following application of internal standard, spray solvent and a voltage were applied to the paper before mass spectrometry detection. A fingerprint visualization step was incorporated into the analysis procedure by addition of silver nitrate solution and exposing the sample to ultraviolet light.

RESULTS

Limits of detection for cocaine, benzoylecgonine, and methylecgonine were 1, 2, and 31 ng/mL respectively, with relative standard deviations < 33%. No matrix effects were observed. Analysis of 239 fingerprint samples yielded a 99% true-positive rate and a 2.5% false-positive rate, based on the detection of cocaine, benzoylecgonine, or methylecgonine with use of a single fingerprint.

CONCLUSIONS

The method offers a qualitative and noninvasive screening test for cocaine use. The analysis method developed is rapid (4 min/sample) and requires no sample preparation.
The timing and times of painting
Authors: Heywood Ian
Published: September 2017

This article explores three aspects of painting and time: first, the experience of growing older with painting and paintings, particularly those of the recent past, second, the contrast between looking dated, a frequent characteristic of paintings of the recent past, and looking new or contemporary, and finally, the distinction between the ways in which painting is both the subject and the object of time, what I will call the ‘timing of painting’, its capacity to work with time and critical efforts, some historical, others more recent, to assign painting a place in its epoch, its ‘times’.
The viscosity of duration: Painterly surface and the phenomenology of time in the London paintings of Frank Auerbach
Authors: Robinson Anne
Published: September 2017

This article aims to examine our perceptions of temporality in painterly surface and investigate the relationship between subjective perceptions of temporality and emotional ‘affect’ in encounters with painting. Frank Auerbach’s London paintings are taken as examples of ‘painterly’ surface with which to consider the elastic temporality of painting. At the centre of this investigation are the engaged and embodied artist and the engaged spectator, encountering the ‘strangeness’ of painterly surface as an intense experience, offering an enhanced sense of lived temporality: both caught in a circuit defined by Merleau-Ponty: ‘For painters, the world will always be yet to be painted...’.

The discursive array: Towards a politics of painting as time–space production
Authors: Chilver John
Published: September 2017

Modernist articulations of time in painting – based on phenomenological approaches – are not viable today. The adequate recipient of today’s accelerated information flows is more machinic than human: human perception is no longer adequate to technological temporalities. Painting ought now to approach time in registers other than the perceptual. Rejecting the terms of MoMA’s ‘The Forever Now’ exhibition, the argument turns to Buren’s notion of the in situ as a valuable attempt to re-think painting as time–space production. But Buren’s position is based on flaws in his ‘Function of the studio’ essay, and ends up supplying architectural decoration for urban redevelopment that is a far cry from his youthful ambitions. The text then considers conflations of in situ with discursive production in Gillick and Bourriaud. After a critical reading of Joselit’s ‘Painting beside itself’ essay, artworks by Merlin Carpenter, Jutta Koether and Lucy McKenzie are examined. McKenzie’s recent work devises fruitful tactics for interweaving affective opacities and discursive frames. McKenzie is able to play with rhetorics of in situ production without succumbing to reductive understandings of site and authenticity, and without conflating time–space production with discursive production. Such a discursive array can elaborate the dissonances between the discursive and the affective.
Between Bare Life and Everyday Life: Spatializing Europe’s Migrant Camps
Authors: Katz Irit
Published: September 2017

The migrant and refugee camps that proliferated in Europe over recent years reflect extreme, if not bipolar, architectural conditions. While fenced carceral camps with prefabricated units were created top-down by state and municipal authorities, informal makeshift camps of tents and self-made shelters were formed bottom-up along Europe’s migration routes. These contrasting spatial typologies often appear side by side in the open landscapes of rural fields, in urban landscapes at the heart or in the fringes of cities, and in the architectural landscapes of abandoned institutions and facilities such as factories, prisons, airports, and military barracks. The different ways in which camps are created, function, and are managed by multiple and changing actors and sovereignties, substantially influence the form of these spaces. So far, however, the radically different spatial typologies of the camp and the intersections between them have not been comparatively analysed. Based on empirical studies of the recently created migrant camps in Europe, this paper sets out to investigate their various configurations, what they reflect, and how they correspond with the culture and politics that shape them. While this paper mainly focuses on three particular camps in northern France – the container camp in Calais, the makeshift camp in Calais known as the “Jungle,” and La Linière camp in Grande-Synthe – it offers observations and analytical strategies relevant to camp spaces in other spaces and contexts and to camp studies more broadly.
Cryostructuring of polymer systems. 47. Preparation of wide porous gelatin-based cryostructurates in sterilizing organic media and assessment of the suitability of thus formed matrices as spongy scaffolds for 3D cell culturing

Published: September 2017

New gelatin-based cryostructurates have been elaborated and tested as scaffolds for three-dimensional (3D) cell culturing. Scaffold preparation included dissolution of Type A gelatin in dimethylsulfoxide, freezing of such solution, cryoextraction of crystalline phase with cold ethanol, cross-linking of gelatin with carbodiimide in ethanol medium, treatment of the matrix with ethanolic solution of Tris and tanning of the matrix with formaldehyde dissolved in ethanol. The use of organic media during all the preparation stages ensured the sterility of the scaffolds. The matrices thus prepared were seeded with human adipose tissue multipotent mesenchymal stromal cells to confirm the biocompatibility of scaffolds and their possibility to provide necessary environment for the cell growth and differentiation. The cells attached onto the surface of the pore walls, proliferated and differentiated into osteogenic and adipogenic lineages. These results demonstrate that gelatin-based cryostructurates prepared in the sterility ensuring organic media can be used as scaffolds for tissue engineering purposes.
Genuin wissenschaftssprachliche Strukturen
Authors: Thielmann Winfried
Published: September 2017

Lange Zeit galt es als ausgemacht, dass Fach- und Wissenschaftssprache ein- und dasselbe sind. Anliegen dieses Beitrags ist es zu zeigen, dass wissenschaftliche Varietäten zwar qua se fachlich sind, darüber hinaus aber Mittel und Strukturen aufweisen, die im Zusammenhang mit sprachlich zu bearbeitenden wissenschaftstypischen Zwecken stehen. Wissenschaftliche Einzelvarietäten sind daher als Resultate von Sprachausbau zu verstehen, der, auf wissenschaftstypische Zwecke bezogen, an den je spezifischen einzelsprachlich vorgehaltenen Möglichkeiten ansetzt. Für eine Didaktik des Deutschen als fremder Wissenschaftssprache sind in diesem Zusammenhang besonders solche genuin wissenschaftssprachlichen Strukturen einschlägig, die unauffällig sind: diejenigen der alltäglichen Wissenschaftssprache sowie diejenigen der wissenschaftlichen Eristik, die sich vor allem in der illokutiven Dimension realisieren.

Published: September 2017

Lustering, a technique which involved the application of coloured translucent glazes over gilding and silvering was widely used to enrich and decorate altarpieces in the Baroque period. The decorations consist of a micrometric multilayered structure including several color glazes, metallic leaves and bole applied over a plaster ground. The collection of Baroque altarpieces, the oldest dating 1671 and the newest 1775 from the cathedral of Tortosa (Catalonia), is a perfect case of study of the materials used and the techniques employed throughout the period. Further information is obtained from the analysis of the reaction and aging compounds resulting from the interaction among the compounds present in the layers and between the different layers. A combination of sensitive analytical techniques, Synchrotron based μ-XRD and μ-IR and SEM-EDS which enabled the luster samples to undergo analysis without altering their original layered microstructure were selected. The nature of the compounds used to produce the yellow, green, red and blue glazes (pigments, pigment lakes and resins), metallic leaves and boles is presented. Relevant information from historical and conservation viewpoints about the origin and nature of the materials used, the making of the lusters and their reactivity and aging are also discussed.

Published: September 2017

Starting from a critical evaluation of the Question-Answer (Q-A) test that has been used by many theoreticians for establishing the linguistic category of Rheme/Focus, this collective chapter, a by-product of our larger CNRS-project about Information Structuring and Typology (ISTY) introduces a methodology based on a Minimal Communicative Utterance (MCU – often an Answer) and its extensions – Binary Strategy 1 (Theme-Rheme) and Binary Strategy 2 (Rheme-Mneme) as dialogic information structuring (IS) constructions. Section 2 reviews the presentation of Polar and Referent Qs and their Answers in the grammars of several European languages – Finno-Ugric (Estonian, Finnish, Sami) and Indo-European (French, Swedish) – and emphasizes the necessity to take into account discourse typology. Section 3 investigates the formal and semantic correlations of Q-A pairs taken from authentic corpora in various dialogue situations (orally transmitted Northern Sami and its recent written variants, Estonian conversations, French political debates). Section 4 is dedicated to a survey of Qs and As in three Southeast-Asian languages (Mandarin Chinese, Thai and Vietnamese), and a comparison of discourse particles as IS devices in the two groups of languages. The general conclusion suggests new approaches to some unsolved research questions (prosody, “theme-prominence”, interaction of syntax and IS structures).
Influence of Hot Rolling Process on the Microstructure and Mechanical Properties of a Press Hardening Steel
Authors: Hu Kuanhui , Zhou Guifeng
Published: September 2017

In this article, microstructure and mechanical properties of a press hardening steel prepared with different rolling parameters are studied, and the effects of the rolling processes are analyzed. The results show that when the finishing rolling temperatures are 870°C and 900°C and the coiling temperature rises from 640°C to 700°C, the strength of the press hardening steel increases and the elongation decreases. The yield strength of the steel prepared with low finishing rolling temperature is high, but the tensile strength has little difference, and the elongation decreases quickly. The microstructures consist of ferrite and pearlite, but as the coiling temperature rises, the amount of the alloy-carbide precipitates in the ferrite, and grain boundary is reduced significantly. The interlamellar spacing of pearlite gradually becomes narrow and the density of dislocation lines in the ferrite increases slightly. The press hardening steel rolled at the finishing temperature of 900°C and coiled at 670°C has excellent balance of mechanical properties. The yield strength, ultimate tensile strength, and elongation are 370 MPa, 598 MPa, and 19 %, respectively.
Insights into DDT Resistance from the Drosophila melanogaster Genetic Reference Panel
Authors: Schmidt Joshua M , Battlay Paul , Gledhill-Smith Rebecca S , Good Robert T , Lumb Chris , Fournier-Level Alexandre , Robin Charles
Published: September 2017

Insecticide resistance is considered a classic model of microevolution, where a strong selective agent is applied to a large natural population, resulting in a change in frequency of alleles that confer resistance. While many insecticide resistance variants have been characterized at the gene level, they are typically single genes of large effect identified in highly resistant pest species. In contrast, multiple variants have been implicated in DDT resistance in Drosophila melanogaster; however, only the Cyp6g1 locus has previously been shown to be relevant to field populations. Here we use genome-wide association studies (GWAS) to identify DDT-associated polygenes and use selective sweep analyses to assess their adaptive significance. We identify and verify two candidate DDT resistance loci. A largely uncharacterized gene, CG10737, has a function in muscles that ameliorates the effects of DDT, while a putative detoxifying P450, Cyp6w1, shows compelling evidence of positive selection.

It is evident that the speed of scholarly communication goes up tendentious if research products are commu­nicated via social networking platforms. Research­ers use the functionality of these platforms without any difficulties and get means for the fast spread of their achievements and for finding research partners. Speed, flexibility and simplicity become the essential conditions for information infrastructure products if there is an intention to reach the leading position in the market. The unquestionable priority of scholarly communication platforms in Lithuania is given to Web of Science, Scopus, ScienceDirect. Nevertheless, a breakthrough is seen in the global permanent identi­fiers for researchers in ResearcherID and ORCID, the global social networking platforms for researchers ResearchGate and Academia.edu or other. The prog­ress of these products is ensured through the flexible functionality provided with precise insights into the needs of researchers, and it is realized through the interoperability of various information systems. This phenomenon is relevant to the develop­ment of the Lithuanian national information system eLABa. This paper presents the research made to examine the factors of scientific communication that recently leads to the future developments of eLABa repository. Results of this research indi­cate the duplication of data preparation, supply and preservation processes, too, and suggest the interoperability between the systems and processes of the Research Council of Lithuanian, the Research and Higher Education Monitoring and Analysis Center, the national data archive MIDAS, systems of research institutions, the Center of Information Technologies in Education, Claritative Analytics Web of Science, Scopus, DOAJ, SherpaRomeo, Creative Commons, ResearchGate, Academia.edu, ORCID and Google Scholar and The Data Bank of National Bibliography.
Pasitenkinimo bibliotekų paslaugomis gyvenimo kokybės kontekste indeksas: Lietuvos AVB atvejis
Authors: Pečeliūnaitė Angelė
Published: September 2017

The article deals with the problem related to the impact of public libraries’ services on the consumer. The paper presents the summarized results of the independent research (the quality of life interface between library activities and community members) – the index of the satisfaction of services (IS) of the Lithuania counties’ public libraries in the context of quality of life. The index was calculated with an evaluate of the weights of the services, coupled with the impact on quality of life. It was determined that the general index of satisfaction with information services is the largest, but it should be noted that active users are more satisfied with the training organized by the library. Currently, the impact of training on the quality of life is very significant, as it increases social inclusion, reduces information exclusion and strengthens self-confidence. The statistical analysis showed that the IS does not differ significantly between the different Lithuania counties’ public libraries, but statistically significantly depends on the demographic data of population. It is noticed that the competence and helpfulness of librarians was most strongly felt in direct contact, so it largely due to exposure to greater satisfaction with the services, and we believe that effective communication is an additional factor that increases IS. It is important to notice that the impact of the Lithuanian counties’ public libraries services on the consumer’s quality of life is significant. We can confirm the statement that public libraries are a good business for the society.

The Internet of Things is an integral part of the future Web part, which is defined as a global and dynamic network infrastructure, which is capable of self-configuring and is based on standardized and compatible communications protocols, where physical and virtual objects have identification characteristics, physical attributes, virtual personalities that use intelligent interfaces and are directly integrated into the unified information network. The resources of the Internet of Things and services are globally distributed within the information network, so it is necessary to have a mechanism which allows the identification of global smart devices, their services and resources. Typically, the identification consists of the assigning names for the resources and the mechanism of the addressing resources in order to discover and access the remote resources of the Internet of things. Modern networks use the Universal Resource Identifier (URI), which identifies a global resource, its type and a set of equivalent names. The URI uniquely allows to identify physical objects, which are located anywhere in the world, using the Electronic Product Code (EPC) technology. EPC allows URI to also be used with Radio-Frequency Identification (RFID). The RFID technology is used for marking and tracing items, which is based on the use of the frequency signal of the radio in the object tag for information recording and reading. This technology in literature is mentioned as one of the main identification and realization measures of the Internet of Things. The purpose of this article is to review and compare the identification methods of objects of the Internet of Things.
Emigracijos diskurso rėminimas Lietuvos interneto dienraščiuose
Authors: Nabažaitė Erika
Published: September 2017

Primarily, mass media, together with online dailies, which became popular due to its activity changes, makes an increasing impact on thinking, beliefs and conduct of the society. By emphasizing aspects of various actual social issues of the society in news agendas, such as emigration, and framing them in a discourse, mass media influences an attitude of the society toward the issue of emigration; it forms an assessment of the country of origin and induces to make decisions whether to stay or leave a country. The article presents the results of a pilot research of emigration discourse framing in Lithuanian online dailies delfi.lt and 15min.lt. Precisely, the research aims at examining an emigration discourse constructed in Lithuanian online dailies and identifying the role of mass media in representing an issue of emigration. The research is carried out by combining the methods of a quantitative content analysis and a critical discourse analysis under the discourse research methodology of N. Fairclough.Furthermore, the research has revealed that the role of mass media in representing emigration can be assessed as a formation of tendencies and regularities that motivate to depart from Lithuania. The pursuit of mass media to form tendencies is revealed by a demand to enlighten an issue of emigration in a field of political realities and international events, which are particularly significant to Lithuania, to provide a topic of emigration in the most readable news sections of online dailies, not describing it in detail, but relating it to the most favorable public realities, namely, the welfare of the people and the financial situation of the country. The issue of emigration presented in mass media is constructed by a negative one-sided discourse, which forms positive frames of emigration. Moreover, it has been ascertained that a negative valuation of Lithuania as the country of origin is predominant in online dailies. There are very distinct tendencies to propagate an economic migration, whereas a positive evaluation of the country is very abstract and it does not reveal any specific peculiarities of Lithuania, which would be a reason to stay in this country. Finally, the emigration discourse in online dailies can by characterized by an emotional, biased rhetoric, which further intensifies an expression of tendencies formed by mass media.

La información actual sobre el uso de inhibidores de la producción de ácido clorhídrico (inhibidores de bomba de protones y antagonistas de los receptores de histamina H2), en pacientes no críticos hospitalizados para la profilaxis de úlceras por estrés escontroversial. Con el fin de evaluar la pertinencia de este grupo de medicamentos en conformidad con el riesgo de sangrado gastrointestinal medido por la escala de Herzig et al. {Risk factors for nosocomial gastrointestinal bleeding and use of acid-suppressivemedication in non-critically ill patients, J. Gen. Intern. Med., 28(5), 683-690 (2013)}, se realizó un estudio observacional descriptivo longitudinal con recolección retrospectiva de la información, el cual incluyó todos los pacientes mayores de 18 años sin sangrado gastrointestinal y con más de tres días de hospitalización, en el servicio de medicina interna de un hospital de tercer nivel de Bogotá. Según esta escala, el 64% de los pacientes se clasificó en bajo riesgo, el 22,3% en medio-bajo, el 6,7% en medioalto,y el 6,7% en alto. La prescripción profiláctica de inhibidores de la secreción ácidase realizó en el 67% de los pacientes de bajo riesgo, en el 57% de los de medio-bajo y en el 100% de los pacientes de riesgo medio-alto y alto. Cerca de la mitad (55,35%) de los pacientes recibieron un antiulceroso sin requerirlo; por lo tanto, se recomiendarealizar actividades educativas dirigidas al personal prescriptor, con el fin de hacer un uso adecuado de este grupo de medicamentos.
Chloride ingress in concrete: limestone addition effects

This paper presents analysis and evaluation of experimental results of chloride ingress and chloride-induced corrosion resistance of concrete made with Portland limestone cement (PLC). The results were mined from 169 globally published studies from 32 countries since 1989, yielding a matrix of 20 500 data points. This study showed that chloride ingress in concrete increases with increasing limestone (LS) content, within the range permitted in BS EN 197-1:2011. However, this effect is less for PLC concrete mixes designed for strength equal to corresponding Portland cement (PC) concrete mixes than those designed on an equal water/cement (w/c) basis. The results also showed that Eurocode 2 specifications for chloride exposure, in terms of characteristic cube strength of concrete or w/c ratio, may need to be reviewed for the use of LS with PC. This study also investigated other influencing factors such as cement content, LS fineness, the method of producing PLC, aggregate volume content and particle size, combined chloride and sulfate environment, curing and exposure temperature. A comparison was made for the performance of PLC concrete in terms of pore structure and related properties, strength, carbonation and chloride ingress. Procedures to improve the resistance of PLC to chloride ingress in concrete are proposed.
EVALUACIÓN DE INVERSIONES A LARGO PLAZO EN EL SECTOR FARMACÉUTICO
Authors: Martínez Garcés Josnel
Published: September 2017

El presente artículo tiene como objetivo analizar los métodos de evaluación de las inversiones a largo plazo en activos fijos, tecnología y capacitación del recurso humano, utilizados por el sector farmacéutico del estado de Zulia (Venezuela). Metodológicamente, es de tipología descriptiva, con un diseño no experimental de campo y transversal. La población fue constituida por las siete (7) farmacias inscritas y activas en el Registro Municipal de la Alcaldía Bolivariana del municipio Jesús Enrique Lossada del Estado de Zulia al mes de mayo de 2015. Se utilizó el cuestionario estructurado como instrumento de recolección de datos aplicado a los gerentes y/o administradores, quienes fueron las unidades informantes; el mismo fue validado por cinco (5) expertos y mediante el nivel de confiabilidad, siendo el Alpha-Cronbach de 0,89. Los resultados demuestran que si bien pocas empresas acuden a los métodos tradicionales para evaluar las inversiones en propiedades, planta, equipos y tecnología, la mayoría aplica los destinados a evaluar inversiones en capacitación del talento humano. En conclusión, los métodos menos usados son aquellos que requieren la aplicación de fórmulas aritméticas (VPN, TIR, IR), evidenciando así que estas empresas carecen de personal calificado para usar e interpretar estos últimos. Se recomienda maximizar su uso para garantizar la salud financiera de estas organizaciones, así como aplicar los correctivos cuando la capacitación brindada al trabajador no produzca el efecto esperado. ABSTRACTThis article aims to analyze the methods of assessing long-term investments in fixed assets, technology and training of human resources used by the pharmaceutical sector of Zulia (Venezuela). Methodologically, the typology is descriptive, with a non-experimental field not a cross design. The chosen sample consisted of seven (7) registered and duly active pharmacies in the Municipal Register of the Bolivarian Mayor City of Losada - State of Zulia in May 2015. A well structured questionnaire was used as an instrument for data collection applied to managers and / or administrators who were reporting units. It was validated by five (5) experts and the level of reliability using the Cronbach Alpha was 0.89. Results show that while only a few companies flock to traditional methods to evaluate investments in property, plant, equipment and technology, the majority applies them to assess the investment used for the training of human talent. In conclusion, the least used methods are those that require the application of arithmetic formulas (NPV, IRR, IR) thus showing that these companies lack qualified personnel for the use and interpretation of these methods. It is strongly recommended, in order to maximize its use, to ensure that these organizations are financially healthy, and at the same time proceed to apply the necessary correctives when the training provided to the worker does not produce the desired effect.

Authors: Valdez David Mireya
Published: September 2017

La Red de Relaciones Socioproductivas es una forma de trabajo cooperativo que involucra a actores de un espacio rural, dedicados a la producción y comercialización de rubros agropecuarios determinados, así como del desarrollo de la idiosincrasia cultural local. En esta investigación, se utilizó el método etnográfico que permitió explicar las pautas para la configuración de una red en el municipio Andrés Eloy Blanco del Estado Lara, Venezuela. Para ello se utilizaron las técnicas de grafos de Euler, que determinó los nodos, la ideográfica que permitió clasificar los elementos de la red y que posteriormente a través del método etnográfico analizó la estructura funcional de la misma. Se concluyó, que las pautas para la configuración de esta red facilitará el establecimiento de relaciones socioproductivas encaminadas a mejorar la calidad de vida de sus integrantes, con incidencia en el desarrollo de su territorio, que activa la capacidad de interrelación entre los integrantes de las organizaciones, ya que implica no solo un sector, sino todos los sectores interconectados, no solo entre ellos mismos sino con aquellas organizaciones y actores que les brinden oportunidades y beneficios.

Este artículo tiene como propósito analizar las relaciones fronterizas entre España y Marruecos, entre las ciudades de Ceuta y Tetuán y de Melilla y Nador, y la necesidad de incorporar un servicio público de transporte entre estas ciudades. Actualmente, las ciudades autónomas disponen de una serie de ventajas económicas y fiscales, y se consideran claves para la UE. Aunque los pasos de Tarajal y de Beni Ensar son muy transitados no se dispone de un servicio de transporte público regular en autobús que comunique las ciudades. La economía marroquí se encuentra en un proceso de apertura y debe desarrollar el sector transportes, en infraestructuras y servicios, debido a la contribución de este sector respecto a otros sectores económicos. La metodología utilizada es de tipo de descriptivo basada en el análisis documental. Los resultados obtenidos muestran la necesidad de formalizar y regular la movilidad de los habitantes de ambos países dada la peculiaridad geográfica de las ciudades de Ceuta y Melilla.
