Pengaruh Bukaan terhadap Kenyamanan Suhu pada Masjid Jakarta Islam Center
Pemanasan suhu pada Jakarta Utara meningkat hingga 2°C dengan rata-rata 32°C. Elemen bangunan yang dapat menurunan suhu yakni bukaan. Masjid Jakarta Islamic Center merupakan bangunan pada area Jakarta Utara yang menggunakan sistem penghawaan alami. Bukaan yang dominan pada masjid yakni jenis kerawangan, dimana jenis ini minim dalam mengalirkan udara kedalam bangunan. Untuk itu perlu dilakukannya pengkajian mengenai keadaan bukaan yang berpengaruh pada penurunan suhu di masjid. Metode yang digunakan pada penelitian ini deskriptif analisis kuantitatif melalui pengukuran lapangan dengan validasi data melalui simulasi software ANSYS 14.5 serta kuesioner. Penelitian dilakukan pada ruangan masjid yang masih menggunakan sistem penghawaan alami. Untuk hasil penelitian menunjukkan suhu didalam ruang bekisar 28°C - 30°C, kondisi tersebut masih melewati batas dari standar suhu normal ruangan tropis, dan keadaan bukaan berkisar 22,3% berbanding dengan luas dinding masjid, dimana kondisi ini juga masih kurang dari standar luasan bukaan yang telah ditetapkan. Hasil penelitian menunjukkan adanya penurunan suhu yang terjadi dengan adanya luas bukaan yang ditambah pada jenis kerawangan, dimana rekomendasi desain luas bukaan yakni 57,8% berbanding dengan luas dinding masjid dan dapat menurunkan suhu hingga 27,2°C
Examining Why and for Whom Reflection Diversity Training Works
This research introduces a novel approach to diversity training by theoretically developing and empirically testing a model that considers a new training exercise aimed at improving proximal and distal pro-diversity outcomes. This new training exercise, reflection, is proposed to be effective at increasing pro-diversity attitudes and behaviors due to the promotion of one\u27s internal motivations to respond without prejudice. Further, we test a critical trainee characteristic, social dominance orientation (SDO), as a boundary condition of our proposed effects. Results from an online experiment with two time points indicate that reflection can be an effective diversity training exercise and leads to better pro-diversity attitudes and behaviors through one\u27s internal motivation to respond without prejudice. Social dominance orientation moderated these indirect effects, such that reflection was more effective for those high in SDO, counter to expectations. Implications of this research and future directions are discussed
Nano-porosity in GaSb induced by swift heavy ion irradiation
Nano-porous structures form in GaSb after ion irradiation with 185 MeV Au ions. The porous layer formation is governed by the dominant electronic energy loss at this energy regime. The porous layer morphology differs significantly from that previously reported for low-energy, ion-irradiated GaSb. Prior to the onset of porosity, positron annihilation lifetime spectroscopy indicates the formation of small vacancy clusters in single ion impacts, while transmission electron microscopy reveals fragmentation of the GaSb into nanocrystallites embedded in an amorphous matrix. Following this fragmentation process, macroscopic porosity forms, presumably within the amorphous phase.The authors thank the Australian Research Council for

How prior knowledge of LGB identities alters the effects of workplace disclosure
© 2017 Elsevier Inc. Decisions to reveal one\u27s sexual orientation are assumed to be a volitional choice. Prior research has shown, however, that people often learn about the lesbian, gay, or bisexual (LGB) identities of others through indirect means, such as gossip and stereotypical cues (Ambady, Hallahan, & Conner, 1999; Colgan, Creegan, McKearney, & Wright, 2007). We conduct two studies to determine the effects of these forms of prior identity-related knowledge on disclosure outcomes. First, a pre-test of study assumptions demonstrates that recipients of minority sexual orientation disclosures often have prior knowledge of those identities. Second, a survey study examining the target\u27s perspective finds that LGB people often suspect when others have prior knowledge of their identities, and this expected prior knowledge moderates the relationship between identity-management and subsequent experiences of discrimination. Lastly, a lab experiment manipulating the level of prior identity-related knowledge establishes that this information directly influences interpersonal workplace outcomes of disclosures through perceptions of awkwardness but not through liking. Together, these studies demonstrate support for our model of prior identity-related knowledge and highlight the importance of examining both prior identity-related knowledge as well as identity management strategies in predicting LGB workplace experiences
Mapping Ecotourism Potential in Bangladesh: The Integration of an Analytical Hierarchy Algorithm and Geospatial Data
The significance of ecotourism has been increasing due to its potential for biodiversity preservation, economic advancement, and the promotion of sustainability awareness. In this research, geospatial analysis and the Analytical Hierarchy Process (AHP) was employed to identify feasible ecotourism sites in Bangladesh. The study applied Geographical Information System–Remote Sensing (GIS-RS) parameters and weighted overlay techniques for selected ecotourism characteristics, such as natural attractiveness, topographic features, accessibility, proximity to facilities, and community characteristics. The study found that a significant proportion (around 44%) of Bangladesh’s land exhibits high potential for ecotourism. Cox’s Bazar, Chittagong, and Rangamati are particularly favorable ecotourism locations. However, some difficulties emerge in regions that are not easily reachable, such as mangrove forests, and in densely inhabited localities like Dhaka. The research also identified the ecological costs linked with ecotourism, such as the exhaustion of resources, the fragmentation of habitats, contamination, and the disruption of wildlife. The primary recommendations to address the adverse effects include educating the local populace, enforcing regulatory measures, implementing efficient waste management systems, enforcing a stringent code of conduct, providing economic incentives to the local communities, and addressing the issue of food security. The cartographically delineated potential zones have the potential to function as a navigational instrument for global travelers and facilitate the decision-making process of policymakers in the realm of sustainable land resource management in Bangladesh. This study enhances the understanding of the potential of ecotourism and offers valuable insights for advancing responsible and sustainable tourism practices within the nation
Nutrition Situation Analysis in the UAE: A Review Study
This review study aimed to assess the nutrition situation in the UAE using published data from 2010 to 2022. It highlights the gaps and challenges that prevail in addressing the nutrition-related problems in the UAE and the opportunities that have been overlooked. The available literature indicates that the UAE is burdened with more than one form of nutrition-related problems, including being underweight, being overweight, obesity, micronutrient deficiencies, and nutrition-related chronic diseases. It is clear that data on micronutrient deficiencies, protein-energy malnutrition, obesity, diabetes, and other nutrition-related diseases among the UAE population are extremely scarce. The UAE has a high prevalence of obesity and diabetes; however, limited studies have been conducted to document this nutritional phenomenon. Few examples of published data are available assessing the burden of stunting, wasting, and being underweight among children under five years of age. Despite the importance of protein-energy malnutrition, no recent publications analyze its prevalence within the UAE population. Therefore, future studies must be conducted, focusing on malnutrition. Based on the literature, and bearing in mind the magnitude of the health issues due to the UAE population\u27s nutrition negligence, there is an urgent need to assess the population\u27s nutrient behaviors, to aid policy decision-makers in developing and implementing effective health policies and strategies
Assessing Large Language Models on climate information
As Large Language Models (LLMs) rise in popularity, it is necessary to assess their capability in critically relevant domains. We present a comprehensive evaluation framework, grounded in science communication research, to assess LLM responses to questions about climate change. Our framework emphasizes both presentational and epistemological adequacy, offering a fine-grained analysis of LLM generations spanning 8 dimensions and 30 issues. Our evaluation task is a real-world example of a growing number of challenging problems where AI can complement and lift human performance. We introduce a novel protocol for scalable oversight that relies on AI Assistance and raters with relevant education. We evaluate several recent LLMs on a set of diverse climate questions. Our results point to a significant gap between surface and epistemological qualities of LLMs in the realm of climate communication
The Association Between Exposure to COVID-19 and Mental Health Outcomes Among Healthcare Workers
Due to the unprecedented impact of the COVID-19 pandemic on health care systems, there has been great interest in the mental wellbeing of healthcare workers. While most studies investigated mental health outcomes among frontline vs. non-frontline healthcare workers, little is known about the impact of various work-related variables. The present study aimed to examine the association between work-related [i.e., having contact with COVID-19 patients, being redeployed due to the pandemic and availability of sufficient personal protective equipment (PPE)] and subjective (i.e., worries about getting infected or infecting others) exposures and self-reported mental health outcomes (i.e., psychological distress, depressive symptoms, and posttraumatic stress symptoms). Between February and May 2021, 994 healthcare workers employed at a variety of healthcare settings in the Netherlands filled out an online survey as part of the COVID-19 HEalth caRe wOrkErS (HEROES) study. Mental health outcomes were measured using the General Health Questionnaire-12, the Patient Health Questionnaire-9, and the Primary Care PTSD Screen for DSM-5. Approximately 13% reported depressive symptoms, 37% experienced psychological distress, and 20% reported posttraumatic stress symptoms. Multilevel linear models consisted of three levels: individual (work-related and subjective exposures), healthcare center (aggregated redeployment and availability of sufficient PPE), and regional (cumulative COVID-19 infection and death rates). Worries about infection were associated with all three mental health outcomes, whereas insufficient PPE was associated with psychological distress and depressive symptoms. There were no differences in outcomes between healthcare centers or provinces with different COVID-19 infection and death rates. Our findings highlight the importance of adequate PPE provision and the subjective experience of the COVID-19 pandemic. These factors should be part of interventions aimed at mitigating adverse mental health outcomes among healthcare workers during the COVID-19 pandemic
