Background: Geographic weights are vital in the floating catchment area (FCA) method of accessibility measurements due to their simulation of spatial barriers in various ways. When modelling population demand, geographical weights with different distance decay coefficients can reflect diverse distance tolerances in facility utilization and could lead to erratic accessibility results. Quantifying accessibility as the sum of weighted supply-demand ratios can alleviate the distance decay coefficient's influence and generate stable geographic patterns. However, the effects of weighted ratios on different FCA models and resources have not been investigated. Methods: To identify impacts of weighted ratios on various FCA variants, this study contrasted the accessibility calculated from the sum of ratios (access) and the sum of weighted ratios (access ratios) within three prevalent FCA models: enhanced two-step FCA (E2SFCA), modified two-step FCA (M2SFCA), and three-step FCA (3SFCA). In addition, the accessibilities of various resources evaluate the stability of the weighted ratios' effect. This study therefore examined the accessibilities to primary schools, job opportunities, and major hospitals in Shanghai. Shanghai is a case study that provides lessons on using big data to measure accessibility in metropolitan areas. Results: Geographic weights can not only mitigate the impact of the distance decay coefficients, but can also eliminate model features,  which reduces the performance of the M2SFCA's supply decay and the 3SFCA's population demand adjustment in accessibility results. Moreover, weighted ratios tend to overestimate accessibility in marginal communities that lie within fewer catchments, regardless of the resource type. This tendency can lead to an epistemological trap that creates an inaccurate and counter-intuitive perception of resource distribution in a given area. Conclusions: The results identify a gap between the methodological logic and the empirical perception in accessibility measurements. This study concludes that the use of geographic weights needs to be cautious and epistemologically consistent.

Method Approach

The industrial sector is one of the important sector in supporting the development of a region. Utilization of land around the river that is used for industrial activities will affect the quality of river water. The river can be polluted by waste personinating from industries that operating around the river. The catchment area that used for industry, agriculture, urban development, and the use of land for making roads (gravel or footpaths) can affect the flow of surface water and sediments that it brings to the river. Waste generated from industrial activities can pollute rivers which are a source of water for daily needs and affect the development of biota in them. This can affect river water quality

The Impact

The prediction of the stability of a protein is a very important issue in computational biology. Indeed, missense mutations are frequently associated to a change in protein stability, leading usually to destabilization, unfolding and aggregation. However, the direct measurement of the effect of mutations on proteins' stability is often impaired by the large number of mutations that can affect a protein sequence. Therefore, predicting the impact of a mutation on this feature is of remarkable interest to infer the phenotypic effects associated to a genotypic variation. For this reason, many different predictors of the effects of mutations on protein stability have been developed during the past years, and they are available online as Web servers. In the present work, we applied several tools based on different approaches to predict the stability of three proteins involved in the different forms of the rare disease galactosemia, and we compare their different results, describing also the problems that we had to face, the solutions that we have adopted and the lessons learnt from this case study.

Pre Service Teacher

For any different objectives of teaching EYL at primary schools in Indonesia, qualified EYL teachers are urgently needed. Pre-service teaching program is expected to provide experience of using proper English language in classroom setting. This case study aimed at describing the first language (L1) instruction used by the pre-service teachers of English for Young Learners (EYL) at the Universitas Muhammadiyah Malang (UMM). The findings depicted that L1 was used as a language of instruction to explain the materials and to clarify the instruction given in L2. It is recommended for the pre-service teachers of EYL to use L2 with demonstration, L2 Context Clues, and L1 translation. Ultimately, the use of L1 in L2 teaching is mandatory to communicate the topic and enhance the students - pre-service teacher interactions. As for meeting the purpose of interaction, the use of L1 should involve actional, conversational, and non-verbal competences. In the long run, the impact of L1 in L2 learning in earlier levels can be recognized from good interpersonal communication in English.

The Impact

<p style="text-align: justify;">This research explores the impact of effective leadership and targeted interventions in closing the achievement gap of disadvantaged pupils in primary schools. Findings suggest that the case study schools use effective school leaders and a range of targeted interventions including early intervention, small group additional teaching, one-to-one tuition, peer tutoring, parental involvement, booster class, mastery learning, pastoral care, and enrichment programmes. Each of the above success factors and intervention strategies was explored in detail in the paper. The overall conclusions of this study are that the case study schools have closed the achievement gap between disadvantaged pupils and their peers through providing effective school leaders and the use of a range of effective intervention strategies. We would suggest that the case study schools’ stories of how they have closed the achievement gap through providing strong school leaders and the use of targeted interventions are of local and national significance. Our research also suggests the possibilities for further research. The recommendations from the study are that there is a need to replicate and expand this research with a larger sample of the study, in order to explore in detail what works in schools.</p>

Every society is stratified in different classes and they are mainly measured through economic conditions. Diversity among the people in terms of their position, status, abilities is a very common phenomenon in this world. Age, gender, nationality, ethnicity, power, economy are a few influencing factors which are promoting divisions among the group. This research is about social status which trigers lexicon shifts on nucluer family of lembar society. This aims at finding out factors which lead to lexicon shift as well where the shifts mainly occur. The participants were 20 from low socio-economic status with span of age 20 to 50; no particular gender takes into account. Data obtained from this research clearly shows that peoples’ inclination towards prestigious variety comes after their desire to be upper class like. People’s social network/mobility is one of the influencing factor determines people to shift the language. People who possess good education, job opportunities and wealth obviously influence low economic people to use high standard language.

Abstract Remarkable efforts have been made in Translation and Interpreting Studies to test the subservient habitus hypothesis formulated by Simeoni (1998) in his seminal work. In the face of increasing evidence that translators tend to reproduce a given society’s or community’s prevalent norms and contribute to the stability of such norms (Toury 1978), subversive translation practices have been reported (Delabastita 2011; Woods 2012) and indeed promoted as a way of fostering social and cultural change (Levine 1991; Venuti 1992). However, insights into how translators’ subservient or subversive habitus develop and depart from each other are still lacking. In order to shed light on this gray area, this article scrutinizes the contrasts between the habitus of professional legal translators who acquiesce to and who reject the norms governing their positions in the field. Special attention is given to those who decide to abandon the translation field. Their behavior is examined by relating habitus to forms of socialization and studying the implications of their strategies. Based on a case study drawn from interview data, this article focuses on the social practices of resistance and rebellion vis-à-vis subservience, and the impact of both on translation workplaces, work processes, and translators’ futures.
