Bam Earthquake

This study aimed to identify issues that arose during the early response stage of the Bam earthquake as perceived by the aid workers. Eleven people who had been involved in the Bam earthquake response, and who were working for the Red Crescent in Iran or the Kerman University of Medical Science teams, were interviewed. These groups were two of the main organizations providing assistance to victims of the Bam earthquake. The authors used two nonrandom sampling methods, namely, purposive and snowball sampling. The interviewees identified two main barriers for achieving an effective response at the early stage aftermath of the earthquake, as follows: first, the lack of accurate information on the location and extent of the earthquake due to shortage in communication tools and, second, inadequate training on different challenges posed in relation to the disaster, before the earthquake occurred.

This exploratory study sought to uncover service provider perspectives on the early response to COVID-19 in a small community in an advanced industrialized country - the homelessness support sector of the Central Okanagan, British Columbia. Following a case study approach, snowball sampling was utilized in May and June 2020 to achieve a sample size of 30 through a mix of one-on-one interviews and open-ended surveys. Qualitative thematic analysis was used to uncover commonalities among interview responses. Common themes are discussed in relation to three areas of questioning including challenges, successes, and mitigations/areas for future support. While the community came together to support the response, there were challenges and concerns regarding safety and personal protective equipment supplies, social distancing and knowledge transmission within the homeless community, access to food and water, and lack of space for isolating positive cases. The findings illustrate possible research, practice, public health policy, and emergency planning considerations within smaller communities.

The Israel-Palestine conflict is one of the most complex issues in nature; the issues of sovereignty, territorial issues, and much more are still unresolved in the Israeli-Palestine conflict. More specifically, this ongoing conflict had affected the Palestinians' life, identity, psychology, and development. A thorough literature review reveals that there is an absence of scholarly research in the area of academic migration of Palestinian scholars about the educational challenges in Indian universities. This research uses a qualitative approach with case study methods. The researcher used field study and Snowball Sampling methods to select the study samples. The in-depth perception of six cases was analyzed on the issues of their stay in India, educational challenges in universities, a pedagogical transaction in the classroom, and the different cultural contexts (of their home country and destination country). The study revealed the academic disparities they face about language were problematic, and this hampered the conversation. Critically understanding the international scenario and position of the Palestinian scholars, this research study will contribute to the development of an empathetic understanding of the students from different conflict zones.

Objectives: The aim of this study was to investigate the actual condition of the students of University of Rajshahi (RU) regarding drug abuse and addiction. Using case study method the research was conducted with four objectives: (a) to find out how respondents began drug abuse; (b) to discover the causes of their drug addiction; (c) to understand the process of their drug abuse; and (d) to find out the economic, social and health effects of drug abuse. Methods: Case study method was used in this research. Through snowball sampling 18 drug- addicted students of RU were selected as respondents. In-depth interview with a schedule was used to collect data from the respondents in January 2019. Results: Findings of the study show that the causes of drug addiction included curiosity, frustration, friends’ request, neglect from family and friends etc. The drugs which they usually abused were Yaba, Phensydyle, Ganja (Weed), Chuani etc. Their average monthly expenditure for collecting drugs was in between Taka 8,000-10,000. They collected those drugs from rickshaw pullers at different points within the campus and from Mizaner Mor, Budhpara slum and other places outside the campus. The respondents opined that drugs were available if sufficient money could be spent. The respondents had senior and junior fellow students and local boys as companions while taking drugs. Most of them faced physical problems after taking drugs, and some of them tried to get rid of this curse of drug addiction. Conclusion: The findings of this research show that the rate of drug addiction among the students of RU was quite alarming. Therefore, all stakeholders including the students, guardians, teachers, university authority, the law makers and law enforcing agencies, researchers, civil society, NGO’s and the state must come forward together to combat this formidable foe.

Abstract In this paper, we propose a new methodology and test system to enable the early detection and precise localization of Time-Dependent-Dielectric-Breakdown (TDDB) occurrence in Back-End-of-Line (BEOL) interconnection. The methodology is implemented as a novel Integrated Reliability Test System (IRTS). In particular, through our methodology and test system, we can easily synchronize electrical measurements and emission microscopy images to gather more accurate information and thereby gain insight into the nature of the defects and their relationship to chip manufacturing steps and materials, so that we can ultimately better engineer these steps for higher reliable systems. The details of our IRTS will be presented along with a case study and preliminary analysis results.

Abstract Inclusion of cerium (Ce) oxide particles as an abrasive into chemical mechanical planarization (CMP) slurries has become popular for wafer fabs below the 45nm technology node due to better polishing quality and improved CMP selectivity. Transmission electron microscopy (TEM) has difficulties finding and identifying Ce-oxide residuals due to the limited region of analysis unless dedicated efforts to search for them are employed. This article presents a case study that proved the concept in which physical evidence of Ce-rich particles was directly identified by analytical TEM during a CMP tool qualification in the early stage of 20nm node technology development. This justifies the need to setup in-fab monitoring for trace amounts of CMP residuals in Si-based wafer foundries. The fact that Cr resided right above the Ce-O particle cluster, further proved that the Ce-O particles were from the wafer and not introduced during the sample preparation.

The research, which was conducted in the village of Oepaha, Nekamese District, Kupang Regency, from June to July 2019, aims to identify marketing channels, capabilities and margins, and the share and benefits of celery marketing for farmers. The location of the research was determined using purposive sampling methods, considering that the location was the most important supplier area for celery in Kupang Regency. The population in this study was the farming community in Oepaha Village, Nekamese district, Kupang Regency,in the amount of 96 celery farmers. The sampling methods is carried out by simple random sampling according to the Slovenian formula, so that a sample of 49 celery farmers is obtained. Sampling for marketing institutions was determined by selecting the marketing institutions which directly involved in celery marketing using snowball sampling methods. In the end, respondents selected marketing institutes consisting of village collectors amounted to 4 people and retailers amounted to 4 people. The analysis of the data used in this study includes descriptive analysis, marketing margin analysis, farmer's share analysis and marketing profit analysis. The results showed that the marketing channel for celery carried out by farmers consisted of two channels, namely farmers directly to consumers and farmers to consumers through intermediaries, namely village collectors and retailers. Celery marketing functions that arise are the functions of sales, purchases, transport, standardization and financing and market information on the zero level channel,while sales, purchasing, transportation, storage, standardization, and financing, as well as market information, run on the second level channel. The marketing margin at zero level is Rp. 51.000,-, while the second level marketing channel is Rp. 17,000 at the collector and Rp. 34,000 at the retailer. The percentage of farmer’s share received by farmers is 25% at zero level and 25% at second level channel. The profit from celery marketing in the zero level marketing channel is Rp. 8.261 (farmers), the second level marketing channel is Rp. 16,688 (farmers), Rp. 15.267 (collectors' traders), Rp. 28,029 (retailers).

Cities and nations worldwide are pledging to energy and carbon neutral objectives that imply a huge contribution from buildings. High-performance targets, either zero energy or zero carbon, are typically difficult to be reached by single buildings, but groups of properly-managed buildings might reach these ambitious goals. For this purpose we need tools and experiences to model, monitor, manage and optimize buildings and their neighborhood-level systems. The paper describes the activities pursued for the deployment of an advanced energy management system for a multi-carrier energy grid of an existing neighborhood in the area of Milan. The activities included: (i) development of a detailed monitoring plan, (ii) deployment of the monitoring plan, (iii) development of a virtual model of the neighborhood and simulation of the energy performance. Comparisons against early-stage energy monitoring data proved promising and the generation system showed high efficiency (EER equal to 5.84), to be further exploited.

Abstract Background Organisational change in health systems is common. Success is often tied to the actors involved, including their awareness of the change, personal engagement and ownership of it. In many health systems, one of the most common changes we are witnessing is the redevelopment of long-standing hospitals. However, we know little about how hospital staff understand and experience such potentially far-reaching organisational change. The purpose of this study is to explore the understanding and experiences of hospital staff in the early stages of organisational change, using a hospital redevelopment in Sydney, Australia as a case study. Methods Semi-structured interviews were conducted with 46 clinical and non-clinical staff working at a large metropolitan hospital. Hospital staff were moving into a new building, not moving, or had moved into a different building two years prior. Questions asked staff about their level of awareness of the upcoming redevelopment and their experiences in the early stage of this change. Qualitative data were analysed using thematic analysis. Results Some staff expressed apprehension and held negative expectations regarding the organisational change. Concerns included inadequate staffing and potential for collaboration breakdown due to new layout of workspaces. These fears were compounded by current experiences of feeling uninformed about the change, as well as feelings of being fatigued and under-staffed in the constantly changing hospital environment. Nevertheless, balancing this, many staff reported positive expectations regarding the benefits to patients of the change and the potential for staff to adapt in the face of this change. Conclusions The results of this study suggest that it is important to understand prospectively how actors involved make sense of organisational change, in order to potentially assuage concerns and alleviate negative expectations. Throughout the processes of organisational change, such as a hospital redevelopment, staff need to be engaged, adequately informed, trained, and to feel supported by management. The use of champions of varying professions and lead departments, may be useful to address concerns, adequately inform, and promote a sense of engagement among staff.
