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

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 support and the staff at the ANU Heavy Ion Accelerator Facility for their continued technical assistance.

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

The emergence of synaesthesia in a Neuronal Network Model via changes in perceptual sensitivity and plasticity

Synaesthesia is an unusual perceptual experience in which an inducer stimulus triggers a percept in a different domain in addition to its own. To explore the conditions under which synaesthesia evolves, we studied a neuronal network model that represents two recurrently connected neural systems. The interactions in the network evolve according to learning rules that optimize sensory sensitivity. We demonstrate several scenarios, such as sensory deprivation or heightened plasticity, under which synaesthesia can evolve even though the inputs to the two systems are statistically independent and the initial cross-talk interactions are zero. Sensory deprivation is the known causal mechanism for acquired synaesthesia and increased plasticity is implicated in developmental synaesthesia. The model unifies different causes of synaesthesia within a single theoretical framework and repositions synaesthesia not as some quirk of aberrant connectivity, but rather as a functional brain state that can emerge as a consequence of optimising sensory information processing

Impact of English private tuition classes on students’ academic performances: the case of ordinary level students in Sammanthurai Education Zone

The purpose of the paper is to identify the influence of private tuition classes on students’ academic performance and the other factors that influence student academic achievement among ordinary level students in the Sammanthurai zone. The sample of the study was enrolled 100 respondents by random sampling technique and questionnaire survey used to collect data from participants. A quantitative research method deals with quantifying and analyzing variables in order to get results. The data collected was analyzed using regression and Chi-square test via SPSS 21. This study reveals that the number of students takes up private tuition classes for English subjects is increasing. The number of students among the students engaging in English private tuition classes, which were failed in the ordinary level final examination, is very less. So, it stated that there is a significant role for private tuition classes in students’ academic performances. From the questionnaire responses, the researcher was able to found out the other relative factors which support the students in their academic activities. They are environment, social skills, and parents’ education level as well. Even though, English is in the second language level for every Tamil-speaking individual. As a reason, the students living in the Sammanthurai zone and especially Tamil medium students are facing many untold hardships and problems in capturing the English language

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

Altered processing of sensory stimuli in patients with migraine

Migraine is a cyclic disorder, in which functional and morphological brain changes fluctuate over time, culminating periodically in an attack. In the migrainous brain, temporal processing of external stimuli and sequential recruitment of neuronal networks are often dysfunctional. These changes reflect complex CNS dysfunction patterns. Assessment of multimodal evoked potentials and nociceptive reflex responses can reveal altered patterns of the brain's electrophysiological activity, thereby aiding our understanding of the pathophysiology of migraine. In this Review, we summarize the most important findings on temporal processing of evoked and reflex responses in migraine. Considering these data, we propose that thalamocortical dysrhythmia may be responsible for the altered synchronicity in migraine. To test this hypothesis in future research, electrophysiological recordings should be combined with neuroimaging studies so that the temporal patterns of sensory processing in patients with migraine can be correlated with the accompanying anatomical and functional changes
