Objective: Malaysia is currently facing a phenomenon where a growing portion of its older population experiencing a decline in their employment participation rate. Simultaneously, most job vacancies are filled by foreign workers as a result of a labour shortage. One of the ways to substitute foreign workers is to utilise skilfully and experienced older workers. However, such requires the willingness of business organizations to hire these workers. Therefore, the main objective of the present study is to predict the relationship of managers’ attitudes and subjective norm with their intention to hire older workers, with age as a moderating variable.
Methodology: The Theory of Planned Behaviour was identified to include the age of respondents as the moderator on the relationships between attitudes and hiring intention. Cross-sectional data were collected from managers of business organizations via personal administered quantitative surveys questionnaire. Hypotheses were tested using structural equation modelling (SEM-PLS).
Results: The response rate was 78% (n=468). The research model accounted for a moderate portion of the variance in overall hiring intention (R2=0.377) and future hiring intention (R2=0.392). The findings suggested that: (1) attitudes and subjective norm are related to overall hiring intention and future hiring intention; (2) age has a moderating effect on the relationship between attitudes and overall hiring intention, but there is no moderating effect on the relationship between attitudes and future hiring intention.
Implication: The empirical result has important implications for human resource strategists, academic researchers and public policymakers as it serves as an additional fuel to combat the nation's acute labour shortage by hiring able and willing older workers.

Published: May 2020

Misconceptions of teaching mathematics in elementary schools often occur, not only to students but also experienced by teachers. Elementary school teachers are required to master many subjects where not all learning material (one of them mathematics) can be mastered by the teacher well. An elementary school teacher may be proficient in the field of language, but on the other hand is weak in the field of mathematics. So that it should be suspected, one of the causes of misconception in students is the teacher. Therefore, through a qualitative research approach, the types and causes of misconceptions in mathematics learning in elementary schools will be revealed by teachers. Research data was revealed through questionnaires and interviews. The findings show that there have been "type misconceptions: pre-conception, undegenneralization, and modeling error" that are stable, permanent and rooted in mathematics teaching in elementary schools
L’Hybridation: une étude sur l’apprentissage de langues étrangères

Published: May 2020

This article is the partial result of an investigation carried out with the students of the Degree Program in Modern Languages ​​of the University of Caldas, Colombia. This research was likewise integrated into a second study concerning the Didactics of the Grammar of Foreign Languages. The research arose from the linguistic hybridization that language teachers have perceived in the correction of the written production of students who simultaneously learn several languages. We analyze, in the current investigation, the phenomenon of linguistic transfer through a corpus of authentic texts written by students. This research focuses on two primary objectives: to identify the phenomenon of transfer at the scriptural level and to determine the pedagogical implications of the language loan in the simultaneous learning of several foreign languages. The methodology is based on an analytical-descriptive approach whose instruments for collecting information were an interview, a survey and a corpus of 50 authentic texts produced by the students. We made a description of the discursive unit and then we carried out a morphosyntactic, semantic and pragmatic analysis of each text. The systematization of the information gathered threw us among the conclusions that the mixture of languages ​​in written production is essentially due to the similarity between them, that is, due to their nature of related languages ​​and the approach used for teaching foreign languages, it facilitates the transfer phenomenon when the learning of several linguistic codes occurs simultaneously.

Published: May 2020

Uno de los problemas que enfrentan los niños de educación primaria pertenecientes a los pueblos originarios hablantes de lenguas indígenas, es la escasez de materiales y recursos educativos que atiendan a sus necesidades formativas, sobre todo, considerando el desplazamiento que enfrenta buena parte de las lenguas y culturas indígenas en nuestro país. En este sentido, es un desafío generar estrategias y recursos para preservar estas lenguas frente a las dominantes y de adaptarse a las nuevas formas de comunicación propiciados por las tecnologías de la información y la comunicación.
Como futura docente y formadora de docentes, hablantes de una lengua indígena, se tiene la responsabilidad de contribuir a preservar esta lengua. El Plan de estudios de educación normal propone adecuar contenidos y materiales de regiones culturales y lingüísticas afines al contexto de los alumnos y en los programas de educación primaria indígena se establece: usar la lengua indígena en otras prácticas sociales del lenguaje, donde generalmente se utiliza el español (SEP, 2017 p. 226).
Para atender a estas orientaciones curriculares y a las necesidades del contexto de una escuela primaria indígena, se elabora un libro electrónico con las herramientas tecnológicas que ofrecen Storyjumper y PowerPoint y el uso de la lengua hñähñu, variante lingüística Otomí del Valle del Mezquital. Para el contenido se consideró una forma en la que se moldea la cosmovisión en función de la lengua y la cultura propia de una comunidad indígena (Villavicencio y Salgado, 2014) donde se desarrollan prácticas profesionales, por lo que se define como núcleo temático “el maíz”, a partir del cual se pretende promover alimentos saludables.

Published: May 2020

The high costs of qualified liquid fuels in remote areas of Siberia and the Far East, as well as significant stocks of wood biomass in these areas determine the relevance of the presented studies. The integrated processing of woody biomass into synthetic liquid fuel and electricity will increase the energy and economic efficiency of processing technological waste, as well as improve the environmental situation in these areas. The aim of the work is technical and economic optimization of parameters modular installations of the combined production of electricity and methanol from woody biomass. The article presents an analysis of previously performed work on the topic of research and, based on them, selected one of the most effective ways to process wood biomass - oxidative conversion of this raw material to produce gas enriched in hydrogen and carbon oxides, synthesis of qualified liquid fuels and generating electricity when burning purge gas synthesis process. The technological scheme of modular plants for combined biomass-based production of electricity and synthetic liquid fuel, its mathematical model of its elements and the scheme as a whole are given. On the basis of the selected methods, optimization studies of the operation of a modular energy technology installation were carried out. Analysis of the results showed that the combined production of electricity and methanol based on biomass increases the thermal efficiency of the process by 12% and reduces investment by 15-20% compared with separate production. With an internal rate of return of capital of 15%, the cost of methanol from biomass will be 275-317 dollars per ton. At such a cost, methanol can compete with both boiler-furnace and motor fuels in the eastern regions of Russia.

One of the current trends at present is the development of small energy, which is a particularly urgent task for the Russian Federation with its vast territories and the specifics of the electric power system. In the Russian Federation, the bulk of the electricity is generated at large power plants and transmitted through power lines. 60–70% of the country's territory lacks a centralized power supply, where more than 20 million people live, and the development of small and micro-energy facilities is necessary. Using a synchronous electric reciprocating machine with permanent magnets in power plants of a modular type makes it possible to rationally design an autonomous power supply source, to obtain the most optimal design. The development of methodological design decisions and the optimization of engine design parameters as part of generating and drive complexes is an important scientific task. A mathematical description of thermodynamic processes in a free-piston internal combustion engine, electromechanical and thermal processes occurring in a synchronous electric reciprocating machine with permanent magnets is developed, which is a necessary condition for designing and optimizing the design of an autonomous electric power complex. According to theoretical calculations, in the Matlab application, on the basis of the additional Simulink module, a simulation model of a free-piston internal combustion engine, linear current load calculation units, stator magnetic induction, magnetic induction created by permanent inductor magnets, electromagnetic force were developed and calculated. The created procedure for calculating the parameters of the electromagnetic component of the force of a synchronous machine with permanent magnets allows you to calculate and optimize the design parameters of the inductor and stator element of the electric motor under consideration. Thus, this will allow us to design electric machines with improved energy characteristics, due to the use of the obtained simulation results, which will allow us to use them more efficiently in the composition of generating and drive complexes.

ABSTRACT
Introduction: On Aug. 29, 2005, Hurricane Katrina made landfall along the Gulf Coast of the United States, resulting in the evacuation of more than 1.5 million people, including nearly 6000 physicians. This article examines the relocation patterns of physicians following the storm, determines the impact that the disaster had on their lives and practices, and identifies lessons learned.
Methods: An Internet-based survey was conducted among licensed physicians reporting addresses within Federal Emergency Management Agency-designated disaster zones in Louisiana and Mississippi. Descriptive data analysis was used to describe respondent characteristics. Multivariate logistic regression was performed to identify the factors associated with physician nonreturn to original practice. For those remaining relocated out of state, bivariate analysis with x2 or Fisher exact test was used to determine factors associated with plans to return to original practice.
Results: A total of 312 eligible responses were collected. Among disaster zone respondents, 85.6 percent lived in Louisiana and 14.4 percent resided in Mississippi before the hurricane struck. By spring 2006, 75.6 percent (n = 236) of the respondents had returned to their original homes, whereas 24.4 percent (n = 76) remained displaced. Factors associated with nonreturn to original employment included family or general medicine practice (OR 0.42, 95 percent CI 0.17–1.04; P = .059) and severe or complete damage to the workplace (OR 0.24, 95 percent CI 0.13–0.42; P &lt; .001).
Conclusions: A sizeable proportion of physicians remain displaced after Hurricane Katrina, along with a lasting decrease in the number of physicians serving in the areas affected by the disaster. Programs designed to address identified physician needs in the aftermath of the storm may give confidence to displaced physicians to return.
