High-throughput combinatorial database of electronic band structures for inorganic scintillator materials

For the purpose of creating a database of electronic structures of all the known inorganic compounds, we have developed a computational framework based on high-throughput ab initio calculations (AFLOW) and an online repository (www.aflowlib.org). In this article, we report the first step of this task: the calculation of band structures for 7439 compounds intended for the research of scintillator materials for γ-ray radiation detection. Data-mining is performed to select the candidates from 193,456 compounds compiled in the Inorganic Crystal Structure Database. Light yield and scintillation nonproportionality are predicted based on semiempirical band gaps and effective masses. We present a list of materials, potentially bright and proportional, and focus on those exhibiting small effective masses and effective mass ratios.     

Community acceptance and willingness-to-pay for a hypothetical Zika vaccine: A cross-sectional study in Indonesia

Background

Understanding people’s perceptions of the economic benefits of a potential Zika vaccine (ZV) is critical to accelerating its introduction into either public sector programs or private market. The aim of this study was to assess the acceptance and willingness-to-pay (WTP) for a hypothetical ZV and the associated explanatory variables in Indonesia.

Effectiveness of multimedia presentations in improving understanding of technical terminologies and concepts: a pilot study

In legal cases, ensuring that members of the judiciary and juries have an appropriate understanding of the evidence being presented is integral to the delivery of justice. This pilot study uses a questionnaire-type survey, in Indonesia and Taiwan (Republic of China) to determine the utility of multimedia presentations as a training tool for educating Judiciary and Linguistic (representing educated laypersons) groups. Participants’ understanding of three digital forensic terms was compared; before and after watching videos on the corresponding topics. The findings suggested that 80% of the participants experienced improved comprehension of specific technical terms after watching the multimedia videos. However, improvement in comprehension from viewing the videos reduces with age (ρ = –0.189 with a P value of 0.033 at 95% level of confidence). The study also found that the features of the video (e.g. analogy) affect participant’s understanding. The findings suggested that multimedia presentations are an effective means of improving understanding of technical terminologies and concepts.
