Oliver Wang interviews documentary filmmaker Arthur Dong. Originally from San Francisco, Dong began his career as a student filmmaker in the 1970s before releasing the Oscar-nominated short film, Sewing Woman in 1982. Since then, his films have focused on the role of Chinese and Asian Americans in entertainment industries as well as on anti-LGBQ discrimination. In the interview, Wang and Dong discuss Dong's beginnings as a high school filmmaker, his decision to turn the story of his seamstress mother into Sewing Woman, his struggle to bring together the Asian American and queer film communities and his recent experience in staging a “Hollywood Chinese” exhibit inside a renovated bar in West Hollywood.

Aim: This paper aims to explain the added value increasing method of reject coal which has not utilized by the company. Methodology and Results: The method to increase added value in this study used the agglomeration process of briquettes form that changing composition by adding biomass. The biomass functions to minimize bottom ash produced from burning briquettes so that the briquettes burn entirely. Stages processes in this study consist of characterization, briquetting, physical test, and chemical test. Based on the analysis, reject coal still has a high calorific value of 5,929 cal/gr. Shapes and sizes that were not following needs of coal market or consumer due to reject coal to be a waste. Briquettes have been successfully produced and meet specification requirements based on applicable regulations in Indonesia. Besides physical properties, the briquette meet density requirements which are greater than or equal to 1 gr/cm3 and shatter index value is less than 0.5%. The gas emission test shows below threshold, which is CO 0-30 ppm, H2S 0-3.6 ppm, and NOx is not detected. After evaluation, it showed that by adding 30% biomass, ignition time could be decreased and remaining unburned briquettes or bottom ash was reduced as much as 68.68%. Conclusion, significance and impact study: The bio-coal briquettes is a strategic solution to environmental problems and alternative energy sources that are environmentally friendly, because CO and H2S emissions are still below the threshold, even for NOx not detected. Making Bio-coal briquettes as a solution to the utilization of reject coal mining waste to be used as an alternative energy source has been successfully carried out.

The New South Wales State Government has embarked on a multi-billion dollar programme of pollution abatement in Sydney, The socio-economic and political factors which have prompted this are described, These illustrate the complexities of dealing with pollution problems while social values alter, public organisations experience administrative change and financial pressures, and politicians try to balance environmental and economic objectives, The technical progress of the Sydney initiatives to reduce storm water runoff and sewer overflow pollution is also outlined.

When suicidal behavior is reported, student affairs officers on many campuses notify parents as one component of a multifaceted campus suicide prevention plan. In response to proposals to mandate parent notification, the author argues that practical considerations warrant against expanding state laws to require notification following campus suicide attempts. The recent experience with parent notice at one university confirms the work of earlier researchers who concluded that parents rarely withdraw suicidal students from enrollment. Although a policy of sending the letters may deter further episodes of selfdestructive behavior, parents once alerted to the situation are not likely to intervene in a manner that will reduce significantly the risk of suicide.

This chapter addresses India’s more recent experience of populism at the national level. While India has avoided a return to authoritarianism since the Emergency, populism has been a recurrent feature of Indian politics. The persistence of divided party rule between the national and subnational levels has meant an uneasy tension between two different modes of political mobilization for national office. National–subnational coalitions based on the distribution of pork have undergirded several Congress party governments. However, such coalitions remain inherently unstable given the autonomy of India’s subnational unit, and they are vulnerable to outflanking by populist appeals over the heads of state governments. The electoral success of the BJP under Modi in 2014 illustrates the appeal of populist mobilization in a vertically fragmented patronage-based system.

AbstractThis article examines a subset of multilateral forums dealing with security problems posed by digital technologies, such as cyber warfare, cyber crime and lethal autonomous weapons systems (LAWS).1 It identifies structural issues that make it difficult for multilateral forums to discuss fast-moving digital issues and respond in time with the required norms and policy measures. Based on this problem analysis, and the recent experience of regulating cyber conflict and LAWS through Groups of Governmental Experts, the article proposes a schema for multilateral governance of digital technologies in armed conflict. The schema includes a heuristic for understanding human–machine interaction in order to operationalize accountability with international humanitarian law principles and international law applicable to armed conflict in the digital age. The article concludes with specific suggestions for advancing work in multilateral forums dealing with cyber weapons and lethal autonomy.

General practitioners (GPs) play a critical role in patient acceptance of vaccination. Vaccine hesitancy (VH) is a growing phenomenon in the general population but also affects GPs. Few data exist on VH among GPs. The objectives of this analysis of a population of GPs in the Belgian Wallonia-Brussels Federation (WBF) were to: (1) determine the prevalence and the features of VH, (2) identify the correlates, and (3) estimate the discrepancy in vaccination’s behaviors between the GPs’ children and the recommendations made to their patients. An online survey was carried out among the population of general practitioners practicing in the WBF between 7 January and 18 March 2020. A hierarchical cluster analysis was carried out based on various dimensions of vaccine hesitancy: perception of the risks and the usefulness of vaccines as well as vaccine recommendations for their patients. A total of 251 GPs answered the survey. The average percentage of moderate to high vaccine hesitancy was 50.6%. Three factors were independently associated with increased risk of vaccine hesitancy: an age <50 years old, having no children, and having no contact with selected vaccine-preventable disease (measles, complicated influenza, chronic hepatitis B (HBV), bacterial meningitis, or cervical cancer) in the past 5 years. VH was associated with controversies on vaccines’ safety. GPs who had vaccinated their children against six diseases (MMR, meningococcus C (MenC), HBV, and HPV) tended not to recommend the same vaccines to their patients. Among GPs with all children vaccinated against HBV, only 37.5% recommended catch-up HBV immunization to their patients. In this small cohort of GP, moderate to high VH was associated with controversies on vaccines’ safety and with specific personal characteristics (age <50, no children, and no recent experience with a serious VPD). As previously reported, GPs have different vaccine prescription attitude toward their patients and children. These findings should be confirmed in larger cohorts.
