Borotellurite glass had been widely applied in the field of optical communications and devices. In this work, holmium oxides doped borotellurite glass had been successfully fabricated via conventional melt-quenched technique. The structural properties of holmium doped tellurite glass were found using x-ray diffraction (XRD) method. The nonexistence of sharp peaks in XRD pattern shows that the inclusion of holmium tellurite glass leads to the formation long range of disorderness. The optical properties of the glass system such as refractive index and optical band gap energy are investigated using UV-Vis spectrophotometer. The value of refractive index is found in nonlinear trend along with holmium oxides concentration. It is found that the refractive index is more than 2 at 0.01, 0.03 and 0.04 of holmium concentrations. The optical band gap energy was found in similar trend with refractive index which is in nonlinear pattern. ? 2021 Trans Tech Publications Ltd, Switzerland...

Human activity has boosted carbon dioxide emissions, causing temperatures to rise. The average temperature on Earth is roughly 15��C, but it has been much higher and lower in the past. There are natural climatic changes, but experts say temperatures are already rising faster than at any other period in history. Unplanned urbanization can sometimes backfire, causing negative consequences that harm the economy and contribute to environmental damages, especially in developing countries like Bangladesh. Because of the strong association between land use/land cover and land surface temperature (LST), the study attempted to analyze and estimate LULC and seasonal (both summer and winter) LSTs using Landsat satellite images at 5-year intervals from 1995 to 2020. Later, the study forecasted both LULC and seasonal LSTs for 2030 and 2040 using cellular automata (CA) and artificial neural network (ANN) algorithms for Rajshahi district. As supporting parameters for determining the magnitude of .....

The global use of Web 2.0 applications has generated enormous volumes of user content. Drawing on cognitive load theory, this study examines unexplored factors that influence gift purchase intention of tourists. The authors identify localization and real-time information for shaping tourists' gift purchase intention, which is facilitated by reduced cognitive overload. Analyzes of the study relies on a sample of 273 foreign tourists in Malaysia. A cross-sectional quantitative study is conducted using partial least square structural equation modeling. Results showed that location-based user-generated content and real-time information significantly affect gift purchase intention of tourists. Moreover, real-time information partially mediates the relationship between location-based user-generated content and gift purchase intention. ? 2021 Akdeniz University Publishing House.

This study seeks to gauge the mastery levels of the overall basic science process skills (BSPS) and the specific BSPS amongst the Malay and the Orang Asli upper primary students. The 36-multiple-choice-item BSPS Test was administered to a total of 348 years 4, 5 and 6 students from an urban primary school in Malaysia. The analyses were performed descriptively and inferentially utilizing an independent samples ttest and one-way ANOVA. The findings indicated that: (1) the Malay students showed an acceptable mastery level for the skills of classifying (71.12%) and predicting (67.43%); (2) the Orang Asli students failed to show an acceptable mastery level across all the BSPS; (3) there were statistically significant differences in the mastery levels across all the BSPS between the Malay and the Orang Asli students, favouring the former; (4) among the Malays, year 6 students achieved markedly higher than year 4 students in classifying, and that years 6 students achieved markedly higher than.....

The writing of argumentative essays promotes higher-order thinking skills amongst students regardless of their level of studying only when it involves collaborative argumentation. Hence, argumentation researchers recommend that teachers use group argumentation to teach argumentative essays since Vygotsky?s sociocultural theory believed that group argumentation improves students? writing skills. The study?s objective is to explore the use of group argumentation during the teaching of argumentative essays in English as a Second Language (ESL) classrooms in Malaysia. Hence, the involvement of practitioners is significant so that the full extent of the problem is known rather than being interpreted solely by researchers. This qualitative study was conducted on nine ESL teachers through convenience sampling. Data was collected through online interviews and analyzed using thematic analysis. The findings demonstrated that ESL teachers did not practice group argumentation when teaching argumen.....

Several concerted movements toward mathematical modeling have been seen in the last decade, reflecting the growing global relationship between the role of mathematics in the context of modern science, technology and real life. The literature has mainly covered the theoretical basis of research questions in mathematical modeling and the use of effective research methods in the studies. Driven by the Realistic Mathematics Education (RME) theory and empirical evidence on metacognition and modeling competency, this research aimed at exploring the interrelationships between metacognition and mathematical modeling and academic year level as a moderator via the SEM approach. This study involved 538 students as participants. From this sample, 133 students (24.7%) were from the first academic year, 223 (41.4%) were from the second and 182 (33.8%) were from the third. A correlational research design was employed to answer the research question. Cluster random sampling was used to gather the samp.....

This article examined the consequences of linking health as a regional security issue. Securitisation Theory (hereinafter ST) is an innovative approach to understand how Non-Traditional Security (from now on NTS) is deemed as a posing threat to a referent object. Prioritising NTS issue as a security threat enables the issue to receive a higher degree of importance from policymakers, thereby gathering the resources needed in dealing with the threat. However, addressing NTS issues also bring negative implications; it can divert attention from more concerning issues. This article, therefore, investigated the consequences of securitising health issues at the Southeast Asian level. This was done through triangulating academic materials, ASEAN?s official statements, and semi-structured elite interviews on Southeast Asian health policy discourses between 1967 and 2010. This study argues that while there are some disadvantages to regional efforts in constructing pandemic disease as a regional .....
