Jordanian oncology nurses' knowledge of managing chemotherapy-induced nausea and vomiting
Authors: Al Qadire Mohammad , Alkhalaileh Murad
Published: May 2018

Background:

health practitioners, especially oncology nurses, play an important role in assessing and managing chemotherapy-induced nausea and vomiting (CINV). Oncology nurses need adequate knowledge and skills to optimally assess and manage CINV in oncology settings.

Aim:

the study intended to assess Jordanian oncology nurses' knowledge of assessing and managing CINV.

Methods:

a cross-sectional design was used to survey 229 oncology nurses working in oncology units in three hospitals.

Findings:

most participants were female (62.9%). The age rage was 21–55 years, with a mean age of 29.9 years (SD=6.2). The mean overall knowledge score was low at 4.7 (SD=3.5) (95% CI=4.40–5.01). Poor knowledge of CINV assessment and management were noted.

Conclusion:

oncology nurses' knowledge about the assessment and management of CINV is inadequate, and improvements in knowledge are needed. An educational intervention is recommended, which needs to be tested to ensure that it is both effective and feasible to provide.

Corrosion inhibition of 1018 carbon steel with some ethoxylated fatty amides in hydrochloric acid solution
Authors: Al-Nowaiser F. M.
Published: May 2018

The effect of three compounds of ethoxylated fatty amides with different number of ethylene oxide unit on the corrosion of 1018 carbon steel in 1M HCl has been studied using weight loss and galvanostatic polarization measurements. The percentage inhibition efficiency was found to increase with increasing concentration of inhibitor, number of ethylene oxide unit and with decreasing temperature. The inhibitive effect of these compounds was explained on the basis of adsorption on the metal surface, through their ethoxy groups. The adsorption process follows Langmuir adsorption isotherm. The effect of temperature on the rate of corrosion in the absence and presence of these compounds was also, studied. Some activated thermodynamic parameters were calculated.

Published: May 2018

An experimental investigation has been carried out to understand the effect of split injection concepts on the emission level particularly on the reduction of Nitrogen oxide emission is accompanied with the reduction of Brake thermal efficiency, hence to offset the reduction of thermal efficiency blend of diesel and oxygenated compound Di-ethylene glycol have been used as fuel for the analysis.Thus the emission characteristics of diesel- Di-ethylene glycol are investigated using the single cylinder direct injection naturally aspirated diesel engine using split injection method involving double lobed cams. The double lobed cam was designed to inject fuel in the proportion of 40-60% with an interval of 8Ú between pilot and main injection. The oxygenated compounds Di-ethylene glycol is blended with diesel fuel in the proportion 5% and 7% by volume. The engine was tested using Eddy current dynamometer at a speed of 1500 r.p.m from no load to full load using diesel, 5% and 7% diesel-Diethylene Glycol blend using single injection and split injection. The AVL smoke meter and krypton gas analyzer are used for measuring emission parameters values. The emission curves such as CO, CO2, HC, NOx and smoke with respect to brake power are plotted for both single injection and single injection and compared. From the results, it is found that NOx emission is drastically reduced with split injection using diesel but slightly higher with diesel- Di-ethylene Glycol blend.

Published: May 2018

The Polycrystalline (CdSe)1-x(ZnS)x semiconductor powder with 0<=x<=1 was prepared by controlled co-precipitation method. Pellets made out of the powder, sintered at 800o C in nitrogen atmosphere was used for studies. Electrical conductivity of these samples increased with increasing the temperature from 77-300o K. At a given temperature an increase in conductivity with the increase in composition was observed in samples with x = 0.2 to 0.4 where as decrease in conductivity with the increase in composition occurs in samples with x = 0.7 to 1. For all samples, activation energies were calculated from the linear portions of log s vs 1000/T and the values range between 0.021 eV to 0.042 eV measurements of all samples are found to be negative, indicating n-type conduction in temperature region 77-300oK.From TEP and conductivity studies, carrier concentration and their mobilities were deduced and all the results were reported and suitable reasons were attributed for each observation made.
Detection of Crack and Spallation of Oxide Scales using Acoustic Emission Technique
Authors: Mathiazhagan P.
Published: May 2018

Acoustic Emission has been finding increasing application for monitoring of aging infrastructures. The materials undergo degradation mechanism during long service exposure at high temperature. Experiments have been carried out on recently developed steel grades P91, P92 and E911 used in thermal power plant materials using acoustic emission (AE) technique under isothermal oxidation in air at 950°C and 1000°C upto 5h. AE parameters count and voltage level shows negligible during isothermal heating for the alloys at these temperatures until the test duration, however a sudden increase is AE activity is found while cooling. An enormous increase in AE activity occurs after the start of cooling has been related to spallation of oxide layers. A very large increase in AE parameters for P92 and E911 alloy at 1000°C during cooling from this temperature has been related to cracking of oxide scale. The oxidation specimen was analyzed using various surface analytical techniques such as scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDAX).

Authors: Kumbhar S. R. , Maji Subhasis , Kumar Bimlesh
Published: May 2018

Smart materials are materials with properties that can be significantly altered in a controlled fashion by external stimuli, such as stress, temperature, pH, moisture, electric or magnetic fields. An elastomer comprising a matrix interspersed with micron sized ferromagnetic particles is known as a Magnetorheological Elastomer (MRE). The rheological properties of MREs are altered by the application of an external magnetic field. The characteristic response of MRE is influenced by many factors including; the elastomer matrix, the size, distribution, composition and percentage volume of the ferromagnetic particles, and whether the ferromagnetic particles are aligned in chains or randomly dispersed. During the past two decades the interest in intelligent material based solutions has shown a huge growth. Present work deals with the study of preparation method of Magnetorheological Elastomer mould and testing for its dynamic behaviour. Micron size iron particles are used for the preparation of MRE in order to increase number of iron particles in elastomer matrix. Two different types of MRE moulds are prepared and their dynamic response has been studied. Comparison has been done between MRE mould cured with magnetic field and without magnetic field by testing them with and without application of magnetic field. The results obtained are satisfactory and can be applied for automotive sector to reduce noise and vibrations.

Published: May 2018

Infrared (Visible-Near Infrared-Shortwave Infrared (VNIR-SWIR)) spectroscopy is a cost-effective technique for mineral identification in the field. Modern hand-held spectrometers are equipped with on-board spectral libraries that enable rapid, qualitative analysis of most minerals and facilitate recognition of key alteration minerals for exploration. Spectral libraries can be general or customized for specific mineral deposit environments. To this end, careful collection of spectra in a controlled environment on pure specimens of key minerals was completed using the National Mineral Reference Collection (NMC) of the Geological Survey of Canada. The spectra collected from specimens in the ‘Kodama Clay Collection’ were processed using spectral plotting software and each new example was validated before being added to a group of spectra considered for incorporation into the on-board library of the handheld ASD-TerraSpec Halo near-infrared (NIR) mineral identification instrument. Spectra from an additional suite of mineral samples of the NMC containingREE, U, Th, and/or Nb are being prepared for a new, publicly available spectral library. These minerals commonly occur in carbonatite or alkali intrusive deposits, and as such will assist in the exploration for critical metals.
Strategic design practices in digital innovation: Findings from strategic design projects with industry
Authors: Price Rebecca , Kleinsmann Maaike
Published: May 2018

Such is the prevalence of digital systems within today’s organizations that design projects that deal with digital subject matter are inherently strategic. Therefore, the aim of this article is to contribute an understanding of how design practices in digital innovation are informed by strategic renewal. To pursue this inquiry, the article seeks to understand how strategic designers operate in ill-defined but opportunity-rich contexts on projects that concern digital innovation. A practice-led methodology is applied to document an engagement with a fast-moving consumer goods (FMCG) firm for ten weeks – with six design teams responding to design briefs set by the client. The findings are that strategic designers apply design methods and techniques to translate technology-centred briefs into fundamentally human-centred problems to be solved. The strategic ambitions of the client and human-centred emphasis can guide designer practice during the otherwise uncertain and complex journey of digital innovation. Further, this article contributes new knowledge regarding strategic design practice and the nature of hidden constraints that are present during digital innovation.

Authors: Yadav Raghabendra , Chen Baochun , Yuan Huihui , Lian Zhibin
Published: May 2018

The dynamic testing of large-scale structures continues to play a significant role in earthquake engineering research. The pseudo-dynamic test (PDT) is an experimental technique for simulating the earthquake response of structures and structural components in time domain. A Concrete Filled Steel Tube (CFST) built-up pier is a modified form of CFST laced column in which CFST members are connected with RC web in longitudinal direction and with steel tube in transverse direction. For this study, a CFST built-up pier is tested under seven different earthquake time histories having scaled PGA of 0.05g. From the experiment acceleration, velocity, displacement and load time histories are observed. The pier experienced maximum acceleration due to Imperial Valley earthquake and minimum due to Wenchuan earthquake. For the Imperial Valley earthquake the acceleration is magnified by 17 times while for the Wenchuan earthquake the acceleration is magnified by 10 times. The frequency of the pier is found to be 1.41 Hz. The result shows that this type of pier has excellent static and earthquake resistant properties.

Published: May 2018

The Experiment was conducted to study effects of binder mineral addition to the hatchery waste based pelletprocessingon its proximate component and energy value. The study may be beneficial to emerge a new feed resource for local farm businesses. The hatchery wastes those comprised of 30% of egg shells, 60% of un-hatched eggs, and 10% of culled DOC were blended, and mixed with 10% of cassava cake meal(W/W), then mixed well with mineral adsorbent (bentonites or zeolites) at 0, 1, 2, 3, 4 and 5% (W/W). The mixture was conditioned at 80 ºC for 15 min, and extruded to make a pellet with 6 mm of diameter and 30 mm in length, and dried into warm air flow dryer. The moisture, crude protein (CP), ash, ether extract (EE), crude fiber (CF), apparent metabolizable energy (AME), true metabolizable energy (TME), metabolizability(MET) and nitrogen retention (NR) were observed in each pellet. Result of the experiment showed that moisture of pellet was decreased (P<0.05) by zeolites or bentonites addition. Even though the effect ofbinder mineral addition gave different patterns, concentrations of ash, crude protein, ether extract and crude fiber of pellet product were increased by increasing level of mineral adsorbent (P<0.05). Nutrient availability as was represented by AME, TME, MET, and NR were increased by zeolites and bentonites additions (P<0.05). In conclusion, supplementations of bentonites and zeolites in the hatchery waste based pelletcould improve its proximate component concentration and nutrient availability.

Authors: Sanders Ted J.M. , Demberg Vera , Hoek Jet , Scholman Merel C.J. , Asr Fatemeh Torabi , Zufferey Sandrine , Evers-Vermeul Jacqueline
Published: May 2018

In this paper, we show how three often used and seemingly different discourse annotation frameworks – Penn Discourse Treebank (PDTB), Rhetorical Structure Theory (RST), and Segmented Discourse Representation Theory – can be related by using a set of unifying dimensions. These dimensions are taken from the Cognitive approach to Coherence Relations and combined with more fine-grained additional features from the frameworks themselves to yield a posited set of dimensions that can successfully map three frameworks. The resulting interface will allow researchers to find identical or at least closely related relations within sets of annotated corpora, even if they are annotated within different frameworks. Furthermore, we tested our unified dimension (UniDim) approach by comparing PDTB and RST annotations of identical newspaper texts and converting their original end label annotations of relations into the accompanying values per dimension. Subsequently, rates of overlap in the attributed values per dimension were analyzed. Results indicate that the proposed dimensions indeed create an interface that makes existing annotation systems “talk to each other.”
Pregnancy luteoma: a rare presentation and expectant management
Authors: Duru Coteli Sinem Ayse , Orgul Gokcen , Salman Mehmet Coskun
Published: May 2018

Pregnancy luteoma (PL) is a rare cause of non-neoplastic masses in pregnancy. PLs are usually asymptomatic. However, general symptoms like pelvic pain, lumbalgia, constipation or virilization due to active hormone secretion can be detected as the clinical findings of these benign cysts. The definitive diagnosis of PL is most commonly possible with a pathological evaluation after surgical intervention. Therefore, we present a successful management of PL with close follow-up until delivery. Beside the suspicion of malignancy by ultrasonography and magnetic resonance imaging (MRI), the cytological evaluation of ascites revealed benign cells which was helpful to decide expectant management.
A Broadband Impedance-Matching Method for Microstrip Patch Antennas Based on the Bode-Fano Theory
Authors: Bonenberger Christopher M. A. , Kark Klaus W.
Published: May 2018

Considering the narrow bandwidth of microstrip antennas, but also their applicability in upcoming technologies, this paper addresses the problem of wide-band matching, the theoretical bounds on the matching bandwidth and low-cost and low-complexity matching strategies. In this context the Bode-Fano bounds of single mode, linearly polarized aperture-coupled microstrip antennas is evaluated, optimized and compared to the theoretical bounds on matching bandwidth of other common feeding technologies. A detailed study of the input impedance of aperture-coupled patch antennas shows how to widen the Fano bounds. Based on this, a straight-forward and effective method to optimize the Fano bound is given. After optimization of the antennas input impedance, basic matching techniques can be applied, to exploit the enlarged bandwidth potential. As an example a

Effects of wet-pressing induced fiber hornification on hydrogen bonds of cellulose and on properties of eucalyptus paper sheets
Authors: Chen Yangmei , Jiang Yu , Wan Jinquan , Wu Qitang , Wei Zebin , Ma Yongwen
Published: May 2018

The supramolecular structure of eucalyptus pulp cellulose was studied by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) and water retention value (WRV) after subjecting the pulp to pressures of 0.1, 0.2, 0.3, 0.4 and 0.5 MPa. It was interpreted from the FTIR spectra of the sheets after pressing that the amount of intermolecular hydrogen bonds (HBinter) first increased and then decreased as a function of increasing pressure, while the number of the intramolecular hydrogen bonding (HBintra) exhibited an opposite trend. In the pressed fibers, the number of HBintraO(6)H· · ·O(3′) increased by 16% compared to the un-pressed fibers, while the number of HBinterO(2)H· · ·O(6) and O(3)H· · ·O(5) decreased by 23% at 0.3 MPa. XRD analysis showed that the crystallite size corresponding to the diffraction peaks for (002) lattice planes and the crystallinity of eucalyptus fibers were the lowest at a pressure of 0.3 MPa. Pressing produced an irreversible reduction of fiber pore volume, which was manifested by reduced WRV data.
Breakdown Cause and Effect Analysis. Case Study
Authors: Biały Witold , Ružbarský Juraj
Published: May 2018

Every company must ensure that the production process proceeds without interferences. Within this article, the author uses the term “interferences” in reference to unplanned stoppages caused by breakdowns. Unfortunately, usually due to machine operators’ mistakes, machines break, which causes stoppages thus generating additional costs for the company. This article shows a cause and effect analysis of a breakdown in a production process. The FMEA as well as quality management tools: the Ishikawa diagram and Pareto chart were used for the analysis. Correction measures were presented which allowed for a significant reduction in the number of stoppages caused by breakdowns.
R&D in Poland: Is the Country Close to a Knowledge-Driven Economy?
Authors: Chybowska Dorota , Chybowski Leszek , Souchkov Valeri
Published: May 2018

Poland has a strong ambition to evolve rapidly into a knowledge-driven economy. Since 2004, it has been the largest beneficiary of European Union cohesion policy funds among all member states. Between 2007 and 2013, Poland was allocated approximately EUR 67 billion, whereas for 2014-2020 the EU budget earmarked EUR 82.5 billion for Polish cohesion policy. This means that in the coming years, Poland’s R&D intensity will grow. But the question remains: is 27 years of free market economy enough to enable a country’s economy to become knowledge-based ? This paper offers an analysis of Polish R&D expenditures and investments in terms of their sources (business, government or higher education sectors), types (European Union or state aid) and areas of support (infrastructure, education or innovation). It also characterises the Polish R&D market with its strengths and weaknesses. Then, it examines the process of technology transfer in Poland, comparing it to best practice. Finally, the paper lays out the barriers to effective commercialisation that need to be overcome, and attempts to answer the question raised in its title.

Electro-osmotic flow of a third-grade fluid past a channel having stretching walls
Authors: Parida Mamata , Padhy Sudarsan
Published: May 2018

The electro-osmotic flow of a third grade fluid past a channel having stretching walls has been studied in this paper. The channel height is taken much greater than the thickness of the electric double layer comprising of the Stern and diffuse layers. The equations governing the flow are obtained from continuity equation, the Cauchy’s momentum equation and the Poisson-Boltzmann equation. The Debye-Hückel approximation is adopted to linearize the Poisson-Boltzmann equation. Suitable similarity transformations are used to reduce the resulting non-linear partial differential equation to ordinary differential equation. The reduced equation is solved numerically using damped Newton’s method. The results computed are presented in form of graphs.

Published: May 2018

In the this paper, a new modified method is proposed for solving linear and nonlinear Lane-Emden type equations using first kind Chebyshev operational matrix of differentiation. The properties of first kind Chebyshev polynomial and their shifted polynomial are first presented. These properties together with the operation matrix of differentiation of first kind Chebyshev polynomial are utilized to obtain numerical solutions of a class of linear and nonlinear LaneEmden type singular initial value problems (IVPs). The absolute error of this method is graphically presented. The proposed framework is different from other numerical methods and can be used in differential equations of the same type. Several examples are illuminated to reveal the accuracy and validity of the proposed method.

Development of Diagnostic SNP Markers To Monitor Hybridization Between Sika Deer (Cervus nippon) and Wapiti (Cervus elaphus)
Authors: Ba Hengxing , Li Zhipeng , Yang Yifeng , Li Chunyi
Published: May 2018

Sika deer (Cervus Nippon) and wapiti (Cervus elaphus) are closely related species and their hybridization can result in significant allele-shift of their gene pool. Additive genetic effects and putative heterotic effects of their hybridization on growth performance could confer considerable economic advantage in deer farming. Here, we used double-digest restriction site-associated DNA sequencing technology (ddRAD-seq) and detected ∼320,000 genome-wide SNPs from 30 captive individuals: 7 sika deer, 6 wapiti and 17 F1 hybrids (reciprocal cross). By screening observed heterozygosity of each SNP across four taxonomic groups, we report for the first time a resource of 2,015 putative diagnostic SNP markers (species-specific SNPs for sika deer and wapiti), which can be used to design tools for assessing or monitoring the degree of hybridization between sika deer and wapiti. These ddRAD-seq data and SNP datasets are also valuable resources for genome-wide studies, including trait discovery for breeders of domestic deer.

Published: May 2018

Field experiment was carried out during the growing season in 2014 year on the soil of good rye complex in Experimental Research Station in Lipnik near Stargard. It was examined three variants of fertilisation: 0 – control (KP), N – (KP+N) and S – (KP+N+S). The maize, cultivar P8609, developed very well and responded positively to the fertilisation. Fertilisation with nitrogen and sulphur, as a calcium sulphate containing 17 % sulphur (= 42.5 % SO3) (variant S), as by-product from industrial Flue-gas desulphurisation, had a positive influence on the biometric features of maize plants (height, height to the first cob and thickness of the stems) and physiological parameters (SPAD – leaf greenness index and the assimilation area index – LAI). We found a significant effect of fertilisation with nitrogen and sulphur, as a calcium sulphate (variant S), on yield of fresh mass. There has been an increase of approx. 8 %, from 48.6 t·ha-1 in the variant N (PK+N) to 52.6 t·ha-1. Also the yield of dry mass increased from approx. 25.2 t·ha-1 on the variant N (PK+N) to 25.3 t·ha-1 (variant S). The evaluated grain yield of maize increased from approx. 10 (variant N) to 10.7 t·ha-1, i.e. of 8 %, after using of nitrogen and sulphur fertilisers (variant S).

En este artículo se busca trazar una red de relaciones intertextuales e interdiscursivas a partir de la imagen del curupira. En la primera parte se propone una lectura del “Canto del kurupira y el toche”, interpretado por Alba Lucía Cuéllar, reparando en el contexto ritual de enunciación de los cantos. En la segunda parte se realiza un itinerario de lectura que recorre tres textos literarios donde aparece el curupira. Este ejercicio permite identificar ciertos vínculos entre la tradición oral y la tradición literaria ilustrada, evidenciando una larga historia de intercambios y transferencias culturales que continúa vigente. Asimismo, se manifiestan las tensiones que emergen de una lectura que se debate entre la interpretación del texto literario y el acercamiento a las culturas orales.
Tejiendo nuevos enlaces: La revitalización de una colección etnográfica por la plataforma Compartir Saberes.
Authors: Scholz Andrea
Published: May 2018

Compartir Saberes empezó como proyecto piloto de colaboración entre el Museo Etnológico de Berlín y la Universidad Nacional Experimental Indígena del Tauca (Uneit), Venezuela. La idea básica de tal colaboración, inspirada por la museología crítica, es revitalizar una parte de la colección etnográfica histórica tejiendo nuevos enlaces entre los artefactos y las llamadas culturas de origen, entre el presente y el pasado y entre representantes de diferentes instituciones y países. En el texto se revelan las dificultades y contradicciones que surgieron a lo largo del proyecto. Con toda la problemática, un resultado importante es la creación de una plataforma web para la investigación compartida de la colección etnográfica. Su funcionamiento se explica usando un canasto yeꞌkwana como ejemplo. Al final se plantea si el canasto, además de ser ejemplo y metáfora, sirve como categoría heurística para la red de relaciones que se va tejiendo con el proyecto.
El concepto de taypi ch'ixi como aporte al estudio de la poesía mapuche bilingüe
Authors: Stocco Melisa
Published: May 2018

En los tejidos andinos aymara, el taypi es el centro que ordena las simetrías, asimetrías y ritmos de la práctica textil. Silvia Rivera Cusicanqui retoma el concepto para referirse a un taypi chꞌixi como el espacio donde lo indígena y lo occidental se entretejen y donde se evidencia la vitalidad de la compleja trama cultural latinoamericana. El presente trabajo busca indagar en la profundidad conceptual y la aplicabilidad de nociones como chꞌixi y taypi para analizar la práctica autotraductora en la actual poesía originaria bilingüe como un espacio intermedio pleno de tensiones, un tejido urdido en el conflicto y la complementariedad entre lenguas, culturas y subjetividades. Se analizarán poemas y metatextos de dos autores mapuche, Leonel Lienlaf y Adriana Paredes Pinda, en los que se plantea la tensión entre oralidad y escritura.
Perspectivas híbridas, concepções descentradas: Estéticas do porvir em Laços de família de Clarice Lispector
Authors: Barretto de Castro Thales Augusto
Published: May 2018

La propuesta de este artículo es discutir de qué forma una determinada estética literaria de la materia, presente en la literatura de Clarice Lispector, embiste en la disolución del racionalismo occidental, contribuyendo para la revisión de fronteras tenues pensadas modernamente en relaciones dicotómicas, tales como humanidad y animalidad, naturaleza y sociedad, objetividad y subjetividad, trascendencia e inmanencia, entre otras. En ese sentido, la percepción del mundo presente en algunas narrativas clariceanas puede aproximarse a aquel aspecto del perspectivismo multinaturalista amerindio, que extiende la condición humana a otras especies del universo, dotándolas de intencionalidad. Así, anhelando tejer un diálogo entre antropología y literatura, este ensayo parte del análisis de algunos textos de Clarice Lispector con el fin de interpretarlos, sobre todo, bajo la luz de los postulados teóricos de Eduardo Viveiros de Castro y de Bruno Latour.

Este artículo propone un análisis poético de algunos fragmentos de los cantos marubo que traduzco de modo indirecto del portugués al español: “Raptada por el rayo” (Kaná kawã), “Payé Flor de Tabaco” (Rome Owe Romeya) y “Origen de la vida breve” (Roka), compilados y traducidos por el antropólogo brasilero Pedro Niemeyer Cesarino en su texto Quando a terra deixou de falar: cantos da mitología marubo (2013). Ello con el fin de abordar las imágenes del traducir que nos traen los cantos, tales como el trato con las voces venidas de lejos a las que intenta responder el chamán-traductor con su escucha en “Raptada por el rayo”, la “troca de ojos” invocando su operar como cantador y doble en “Payé Flor de Tabaco” o el canto de la brevedad que recuerda la traducción como variación entre variaciones, siempre transitoria y fragmentaria en “Origen de la vida breve”. Esto me permitirá seguidamente indicar las contribuciones de la poética chamánica marubo para pensar el acto de traducción.
Trama, tejido: pensar la construcción cultural
Authors: Pizarro Ana Irene
Published: May 2018

La multiplicidad de flujos culturales, así como su movimiento interno entre los diferentes sistemas literarios, nos conducen a pensar un sistema de relaciones en donde interfieren varios aportes culturales al mismo tiempo o en secuencia, en una escala de tiempo específica para cada situación, en donde los cruces pueden o no consolidarse y en donde cada flujo posee en el momento una energía diferenciada a partir del contexto histórico —y por esto los hay hegemónicos y subalternos—. Se puede observar un tejido, una trama, en movimiento constante.
Herramientas culturales y transformaciones mentales: Las tecnologías de la información y la comunicación en perspectiva histórico-cultural
Authors: Rodríguez Arocho Wanda C.
Published: May 2018

Este ensayo tiene el propósito de argumentar que el enfoque histórico-cultural (EHC) es una herramienta conceptual útil para comprender y explicar algunas de las principales transformaciones mentales generadas e impulsadas por la creación y el uso de las nuevas Tecnologías de la Información y la Comunicación (TIC). En la elaboración del argumento examino la tesis central del EHC sobre la sociogénesis de la mente y el planteamiento con respecto a que el uso de herramientas y símbolos en la actividad humana cambia la naturaleza de esta y da paso a transformaciones en las funciones mentales. Utilizaré investigaciones procedentes de la arqueología cognitiva y la ciberpsicología para ejemplificar las principales transformaciones en el curso de la historia evolutiva de la especie. De ahí, pasaré a analizar las transformaciones que la investigación contemporánea ha documentado en usuarios de las TIC, en diversas disciplinas. Concluiré con el análisis de lo que esas transformaciones implican para la psicología y la educación.
La complejidad del conocimiento profesional docente y la formación del conocimiento práctico del profesorado
Authors: Rodríguez Pech Juanita , Alamilla Morejón Pedro
Published: May 2018

En el presente ensayo se argumenta acerca de la complejidad de los saberes implicados en la práctica docente, estos han sido descritos en la literatura como diversos, tanto por su contenido como por su representación. Se discute la dualidad existente entre la teoría y la práctica como fuentes del saber profesional docente, así como las razones que se han aducido para explicar la aparente separación entre ambas. Se presenta también el conocimiento práctico del profesorado como un constructo que podría representar un modo de reconciliación de dichos saberes, por cuanto permite la integración reflexiva de distintas fuentes de conocimiento en uno aparentemente de mayor relevancia para la práctica docente. Finalmente, se plantean algunas de las implicaciones que el desarrollo del conocimiento práctico tiene en la formación del profesorado.
Tecnologías en línea populares para viajar: ¿cuáles utilizan los jóvenes universitarios para hacer turismo?
Authors: Castro Ricalde Diana , Peñaloza Suárez Laura , Tamayo Salcedo Ana Leticia
Published: May 2018

Este artículo tiene como objetivo mostrar las herramientas tecnológicas en línea más populares que permiten la planificación y realización de viajes y cuáles son usadas por el estudiantado universitario que se está formando como profesional en Turismo, reconociendo como problema en el ámbito educativo el desconocimiento de las tecnologías utilizadas por el segmento de alumnos y considerando sus efectos en el proceso enseñanza y aprendizaje en un campo dominado por dichas herramientas. Como parte de los fundamentos teóricos se considera el Determinismo Tecnológico, y como método de análisis un enfoque mixto -cuantitativo y cualitativo- para conocer cómo hace turismo online la juventud, qué tecnologías prefiere y qué condiciones determinan sus formas de viajar. Dicha metodología abarcó la aplicación de las técnicas de cuestionario digital y Grupo Focal; la encuesta comprendió una muestra de 236 estudiantes de todos los semestres de la Licenciatura en Turismo de la Universidad Autónoma del Estado de México, y el Focus Group integrado por un total de 10 jóvenes del periodo 2017A. Como parte de los resultados fueron identificadas las herramientas que utilizan comúnmente para comunicarse y buscar información en Internet antes de realizar un viaje; las tecnologías que facilitan la personalización de sus desplazamientos y lo que requieren conocer de Internet para facilitar la realización del turismo y el E-commerce. En las conclusiones se sintetiza qué hace falta conocer en la Universidad en términos de tecnologías para enseñar y aprender durante la formación profesional y así favorecer la realización del E-Tourism.

Los caminos hacia una enseñanza no tradicional de la química
Authors: Ordaz González Gabriel José , Mostue Maj Britt
Published: May 2018

Es preocupante cómo todavía hay docentes (de química) que piensan que la enseñanza es llenar con conocimientos a quienes serían “contenedores vacíos”, es decir, los estudiantes. Posiblemente, esta concepción tradicional-expositiva asumida en la praxis pedagógica contribuye a que la enseñanza de la química esté (o se mantenga) en crisis. El propósito de este ensayo es presentar algunas reflexiones sobre el rol del docente de química a partir de una mejor conceptualización de la enseñanza y del aprendizaje que la ofrecida por la educación tradicional. Esto, como un recordatorio y un llamado de atención para que las personas docentes asuman los retos en la enseñanza de esta ciencia. Una educación, concebida para promover la autonomía en el aprendizaje y la metacognición, obliga al profesorado de química a “enseñar” una ciencia más contextualizada, desde un pensamiento multinivel y con criticismo. Lo anterior, podría contribuir a un mejor entendimiento del conocimiento químico y coadyuvar en los procesos formativos.
Clientelismo y Sistema Político. El Caso del Servicio Exterior Costarricense (1940-1990). Algunos Apuntes Preliminares.
Authors: Cascante Segura Carlos Humberto
Published: May 2018

Este artículo analiza a grandes rasgos las relaciones entre sistema político y servicio exterior, mediante el concepto de clientelismo empleado en las Ciencias Políticas. El objetivo central es determinar la existencia de un sistema clientelar que permitió el desarrollo de un modelo político durante la segunda mitad del siglo XX, a partir del estudio de la integración y patrones seguidos por el grupo de personas que desempeñaron el cargo de jefes de misión. Desde esta perspectiva el estudio sugiere la existencia de ese sistema, así como ciertas pautas que pueden explican su éxito y funcionamiento.

Análisis del impacto en Costa Rica de los ciclones tropicales ocurridos en el Mar Caribe desde 1968 al 2007
Authors: Alfaro Martínez Eric J. , Quesada Adolfo , Solano Chaves Flora Julieta
Published: May 2018

El estudio de la actividad de los ciclones tropicales, así como su caracterización histórica en la región centroamericana, es una prioridad para apoyar las actividades de mitigación del impacto que estos fenómenos provocan en las diversas zonas del istmo. Basado en lo anterior, en este trabajo se definen para Costa Rica, los años de alto o bajo impacto por el paso de ciclones tropicales en el Caribe considerando variables asociadas a la trayectoria del evento, la permanencia del mismo cerca del istmo y la frecuencia de los fenómenos en la cuenca. El análisis mostró que la mayor probabilidad de ocurrencia de los ciclones tropicales cerca de América Central se presenta durante el trimestre agosto-setiembre-octubre. Se observó también, que durante los años que mostraron altas ocurrencias de ciclones cerca de América Central, el Atlántico Tropical Norte presentó campos con anomalías positivas en la temperatura superficial del mar y la humedad relativa en 700 hPa, y negativas en la presión media al nivel del mar. Además, Costa Rica posee una rica fuente en información sobre desastres de origen natural que afectaron directamente centros poblacionales y diversos sectores socio-económicos, como el agropecuario, energía y transporte, entre otros. Esto permitió el detalle de los desastres sufridos en Costa Rica por ciclones tropicales durante las últimas cuatro décadas. El trabajo indicó que la tendencia encontrada en el reporte anual de impactos por eventos hidrometeorológicos, no puede ser explicada totalmente por efectos climáticos, lo que hace necesario incluir variables de otro tipo, como las socio-económicas.
