Chinese L2 acquisition of sense relatedness for shàng “to go up”
Authors: Liang Haiyan , Sullivan Karen 
Published: May 2019

AbstractThis paper examines the relations between the senses of the Chinese polysemous verbshàng“to go up”, in an effort to understand how the various senses of polysemous words are organized in the L1 and L2 lexicons and to shed light on the role they might play in L2 polysemy acquisition. To this end, we analyzed the senses of shàng at the conceptual level, then used these findings to inform an empirical study of the sense relatedness as perceived by L1 and L2 participants. A developmental pattern is identifiable across the L2 proficiency groups. Specifically, the sense relations identified by the L2 groups increasingly approximate those identified by L1 as their proficiency level grows. Both native speakers and learners base their perceptions of sense relatedness on purported conceptual metaphors as well as other factors such as transitivity, function and concreteness – though the two groups apply these concepts in different ways. These findings suggest that learners can access the same conceptual tools as native speakers, but are using these tools in a way that differs from native speakers. Conclusions support the cognitive motivations behind polysemous senses and teaching-oriented findings that overlap in L1 and L2. Conceptual universals should be helpful in L2 vocabulary acquisition.

Authors: Buchukuri T. , Chkadua O. 
Published: May 2019

Abstract
Dirichlet- and Neumann-type boundary value problems of statics are considered in three-dimensional domains with cuspidal edges filled with a homogeneous anisotropic medium. Using the method of the theory of a potential and the theory of pseudodifferential equations on manifolds with boundary, we prove the existence and uniqueness theorems in Besov and Bessel-potential spaces, and study the smoothness and a complete asymptotics of solutions near the cuspidal edges.
Quasi-Linearisation Methods for a Non-Linear Heat Equation with Functional Dependence
Authors: Leszczyński Henryk 
Published: May 2019

Abstract
We consider a heat equation with the non-linear right-hand side which depends on certain Volterra-type functionals acting on the unknown function and on its gradient. We give some natural sufficient conditions for the existence and uniqueness of solutions to this equation. The solution is obtained as a limit of a fast convergent sequence of successive approximations obtained by the quasi-linearisation method.
Typology and contexts of article errors: Investigation into the use of English articles by Hong Kong Cantonese ESL learners
Authors: Chan Alice Yin Wa 
Published: May 2019

Abstract
This paper provides a taxonomy of errors in the use of English articles by Hong Kong Cantonese ESL learners. A study was conducted with 387 Hong Kong Cantonese ESL learners, including 65 students from three local universities and 322 students from five local secondary schools. They did two free writing tasks of about 200–300 words. Over 600 pieces of free writing were obtained. The use of English articles was analyzed and errors were identified. Irrespective of learners’ proficiency levels, similar types of article errors have been observed. While over-extension errors and under-extension errors are both quite common, co-occurrence errors are nearly non-existent. Intended generic reference triggers most problems, although this reference has been least attempted. The function of the noun phrase in which an article error occurs may play a part in error severity, with Object creating most problems for learners, yet the precise effects of noun functions are yet to be determined. It is suggested that more emphasis be put on the teaching of English articles to learners at different proficiency levels. Advanced learners, such as university students, should be engaged in metalinguistic analyses uncovering the subtle differences between the use of different articles in the same linguistic context.
How Much Should a Person Know? Moral Inquiry & Demandingness
Authors: Hartford Anna 
Published: May 2019

Abstract
An area of consensus in debates about culpability for ignorance concerns the importance of an agent’s epistemic situation, and the information available to them, in determining what they ought to know. On this understanding, given the excesses of our present epistemic situation, we are more culpable for our morally-relevant ignorance than ever. This verdict often seems appropriate at the level of individual cases, but I argue that it is over-demanding when considered at large. On the other hand, when we describe an obligation to know that avoids over-demandingness at large, it fails to be sufficiently demanding in individual cases. The first half of this paper is dedicated to setting up this dilemma. In the second half, I show that it cannot be easily escaped. Finally, I suggest that this dilemma impedes our ability to morally appraise one another’s ignorance, and even our own.
Feasibility of Noncontact Chemical Identification and Mapping for Steel Corrosion Using Portable Raman Spectroscopy
Authors: Zhou Zijie , Park Jeong Hoon , Kang Gyu-Hong , Yun Hae-Bum 
Published: May 2019

Abstract
This article presents the portable Raman spectroscopy as a novel noncontact chemical sensing technique for steel corrosion analysis that can be used in field bridge inspection. To validate its feasibility, the portable system was tested with four steel specimen sets by gradually increasing the complexity of corrosion products in atmospheric corrosion. A software algorithm was developed to process a large set of Raman spectra for automated chemical identification and two-dimensional chemical mapping. The portable Raman spectroscopy has advantages over conventional nondestructive evaluation techniques because (i) absolute chemical identification of corrosion products is possible without involving field calibration, (ii) no surface preparation is necessary, (iii) it allows for field inspection for periodic or in situ corrosion analysis, (iv) and because, being a noncontact portable sensing technique, it can be combined with a drone or robot for automated bridge inspection.

Published: May 2019

Abstract
This article presents the results of an experimental study conducted to assess the effect of sustained elevated temperature on the mechanical properties of ultrahigh performance concrete (UHPC). UHPC mixtures were prepared with four different dosages of polypropylene (PP) fibers, and each mixture was exposed to a sustained pre-spalling elevated temperature of 300°C for five durations. The experimental data indicate that the used PP fibers were effective in providing sufficient strength and ductility to UHPC mixtures at room temperature. However, the PP fibers ceased to function as reinforcement in UHPC specimens that were exposed to the elevated temperature for 60 minutes. With an increase in the exposure period after melting of the fibers, the specimens exhibited a brittle mode of failure accompanied with an enhancement in the compressive strength and compressive modulus of toughness and a reduction in the modulus of elasticity and flexural strength. The significance of two variables (exposure duration and fiber content) was evaluated, and correlations between the mechanical properties and selected parameters were obtained by conducting a statistical analysis of the experimental data.

AbstractBinary expression systems like the LexA-LexAop system provide a powerful experimental tool kit to study gene and tissue function in developmental biology, neurobiology, and physiology. However, the number of well-defined LexA enhancer trap insertions remains limited. In this study, we present the molecular characterization and initial tissue expression analysis of nearly 100 novel StanEx LexA enhancer traps, derived from the StanEx1 index line. This includes 76 insertions into novel, distinct gene loci not previously associated with enhancer traps or targeted LexA constructs. Additionally, our studies revealed evidence for selective transposase-dependent replacement of a previously-undetected KP element on chromosome III within the StanEx1 genetic background during hybrid dysgenesis, suggesting a molecular basis for the over-representation of LexA insertions at the NK7.1 locus in our screen. Production and characterization of novel fly lines were performed by students and teachers in experiment-based genetics classes within a geographically diverse network of public and independent high schools. Thus, unique partnerships between secondary schools and university-based programs have produced and characterized novel genetic and molecular resources in Drosophila for open-source distribution, and provide paradigms for development of science education through experience-based pedagogy.

Published: May 2019

Simulated learning experiences (SLEs) assist students to acquire knowledge and skills and are an effective teaching tool in physiotherapy education. The aim of this project was to explore physiotherapy student attitudes towards SLEs as a preparatory component of an introductory clinical placement. The project was a quasi-experimental, pre/post-test repeated measures design. Participants were second year physiotherapy students (n = 57) allocated to a placement which included one week of SLEs and three weeks in a healthcare setting. The SLE week consisted of sessions to develop students’ clinical skills in preparation for placement. Data on participant attitudes towards SLEs were collected via anonymous survey before and after the SLE week, and at the completion of the three week clinical placement. Attitudes of respondents (n = 43) towards SLEs were significantly more positive at the completion of the SLE week. At the completion of the three week clinical placement, all responses remained more positive than at the commencement of the project, however participant responses were generally less positive than at the conclusion of the week of SLEs. Students valued the use of SLEs in preparing for introductory clinical placements. Simulated learning experiences should be considered as a useful tool for pre-placement preparation for early year physiotherapy.
La Salud Mental, un verdadero problema de salud pública
Authors: Cuellar Rivas Lina Ximena 
Published: May 2019

La OMS define la salud Mental como “un estado de bienestar en el cual el individuo es consciente de sus propias capacidades y puede afrontar las tensiones normales de la vida, puede trabajar de forma productiva y fructífera y es capaz de hacer una contribución a su comunidad”.
Dentro de los determinantes de la salud mental además de las características individuales como la capacidad para gestionar nuestros pensamientos, emociones e interacciones con los demás, están los factores: sociales, culturales, económicos, políticos y ambientales en las cuales se incluyen el contexto político como las políticas nacionales, la protección social, el nivel de vida, las condiciones laborales y las redes de apoyo comunitarias.
Dentro de los factores asociados con problemas en salud mental están: la pobreza, enfermedades crónicas, maltrato o abandono en especial en población infantil, abuso de sustancias en especial en la adolescencia, población adulta mayor, grupos minoritarios como: indígenas, sometidos a discriminaciones y violaciones de derechos, población LGTBI, prisioneros o expuestos a conflictos armados o desastres naturales u otras emergencias humanitarias1.
En los países de ingresos bajos y medios, entre un 76% y un 85% de las personas con trastornos mentales graves no reciben tratamiento; en los países de ingresos elevados oscila entre un 35% y un 50%1.

En Colombia se viene observado el incremento de los problemas y trastornos mentales y del comportamiento y la epilepsia, los años de vida potencialmente perdidos por el suicidio, la prevalencia de consumo de alcohol y otras sustancias psicoactivas, las elevadas cifras de violencia2.
Nuevos miedos en la literatura policial de Chile y Argentina
Authors: Muniz Gabriela 
Published: May 2019

El elemento fundante del miedo en la narrativa policial adquiere forma acorde a la sociedad aludida. El objeto temido es cambiante porque se refiere a un presente y puede ser identificado tanto en los tópicos narrativos como en la forma en que estos son narrados. Este artículo busca entender la relación entre el éxito editorial que tiene hoy el género policial en dos países del Cono Sur, Argentina y Chile, y los miedos específicos que estos textos sobre crimen señalan. Teniendo como marco teórico los estudios sobre el miedo y siguiendo la idea de Jacques Rancière de que toda política deriva en reflexión estética, se analiza la manera en que escritores chilenos y argentinos (Roberto Bolaño, Mario Valdivia, Josefina Licitra, Mariana Enríquez y Claudia Piñeiro) enmarcan, explican o distribuyen el mundo sensible, mostrando nuevas manifestaciones del miedo comprendido en lo que sería un “realismo capitalista”. En este caso en particular, se trata de un temor producto de la vulnerabilidad generada en un contexto neoliberal cuyo leitmotiv es el consumo y la exclusión.

Published: May 2019

Logistics outsourcing as a conscious business decision to move internal work or activities to an external supplier has become a means of minimizing cost, reducing internal workload and gaining core competency for organizations as well as Oil and Gas companies in recent times. In spite of the enormous advantages of logistics outsourcing as reported by previous studies such as cost reduction, effective base and warehouse management, improved safety, risk sharing, Knowledge transfer, training and development. However, research has shown that logistics outsourcing have, other times turned into a wellspring of corporate disappointment and dissatisfactions. In this work, the challenges that could lead to an unsuccessful logistics outsourcing were investigated to uncover the inherent challenges and recommend possible solutions to overcoming them. The sample size was focused on the managers and assistant managers in the selected oil and gas companies and their logistics providers. A total of 350 copies of questionnaire titled Logistics outsourcing and organizational performance questionnaire (LOOPQ) was designed and administered to elicit primary information and data from respondents who were chosen from the oil and gas companies and service providers with a 90% respondent rate. Secondary data was obtained from company records. The data for this study were analyzed using the Statistical Package for Social Sciences (SPSS) for both descriptive and inferential statistics. The present study found that the failure of logistics outsourcing in the oil and gas companies can be connected to any of these challenges. The study have exposed the major challenges of logistics outsourcing in the oil and gas companies and recommended that a strategic management of logistics outsourcing which can overcome the challenges inherent in logistics outsourcing and improve organizational performance in the oil and gas industry should include: Provision of New/Standard equipment and regular maintenance by logistics providers, Effective communication network between logistics providers and the selected oil and gas companies under study, provide motivation for members of staff, Advanced Customer/Client Relation Management, ensure good Quality Assurance and Control and effective monitoring of projects.
Infant Feeding and Cardiovascular Disease: A multi-staged analysis from global to country data
Authors: Abul-Fadl Azza M.A. , Al-Jawaldeh Ayoub 
Published: May 2019

Background: Death from cardiovascular disease (CVD) is the leading cause of death globally and in particular in the Eastern Mediterranean region (EMR). The relationship between early feeding practices and CVD remains to be fully established.
Aim: To examine the relationship between early infant feeding practices as risk factors of death from CVD with a focus on high blood pressure (HBP) in the 22 countries of the EMR.
Methods: First: global and regional data were compiled for deaths from CVD, HBP, nutritional deficiencies. Second: data from the EMR countries were compiled for adult obesity, high cholesterol (HC) and blood sugar (HBS) and pollution. Countries from the EMR were divided into high and low risk by HBP and biochemical data. Third: deaths from wasting, stunting, non-exclusive and discontinued breastfeeding and nutritional deficiencies including anemia, vitamin A deficiency, low bone mineral density and Zinc deficiency, were compared in both groups. Fourth: a small scale in-depth study (SSIDS) was conducted for 32 breastfed and 28 non-breastfed mother-child pairs under-five years of age. HBP and high density lipoproteins (HDL) and low density lipoproteins (LDL) and highly sensitive C-reactive protein (HsCRP) were measured.
Findings: Nine EMR countries were identified as high risk for CVD with HBP, obesity, HC and HBS and pollution. Deaths from nutritional deficiencies and feeding practices were higher in this group. In the SSIDS, HsCPR was significantly lower in mothers and children who were breastfed and HDL significantly higher in children introduced foods after 6 months of age.
Conclusions: Optimal infant feeding practices contribute directly and indirectly to reducing deaths from CVD.
