Under environmental regulations, the government restricts the economic activities of polluting OEMs (Original Equipment Manufacturers) in order to improve ecological and economic efficiency. The most direct measure is to limit the production capacity of the companies. Under the condition of limited capacity, the order selection strategy of OEMs will be the direct determinant of the company’s own profits. In the foundry market, there are many low-profit orders, while the number of high-profit orders is limited and uncertain. Companies who choose to wait for high-profit orders must bear the waiting costs and the risk of losing a certain profit. Therefore, it is of great significance for the long-term development of the company to select orders to obtain the best profit under the condition of limited production capacity. This paper takes polluting OEMs as the research object and studies the optimal order selection problems of companies under environmental regulations by establishing order selection decision models for different foundry cycles under the condition of limited production capacity. The study found that in the single foundry cycle, there will be an optimal waiting-time threshold for high-profit orders. Based on this optimal waiting-time threshold, the corresponding order selection strategy can be effectively formulated. However, in the multi-foundation cycle, since the optimal waiting-time threshold of high-profit orders is affected by the long-term average profit, the company’s optimal order selection strategy is based on the long-term average profit maximization.

Vietnam’s rapidly increasing leather and footwear export trade has made a significant contribution to the country’s economic development over recent years. However, the rapid growth of the leather industry causes considerable pollution, which poses increased risks to the environment and human health. A number of policies have been introduced by the government of Vietnam to mitigate the environmental pollution from the tanning industry. They include requirements for tanneries to (i) submit environmental impact assessment reports, (ii) install wastewater treatment systems, and (iii) pay wastewater fees. However, many tanneries in Vietnam did not comply with these regulations. This study aimed at investigating the compliance of Vietnam’s tanneries with environmental regulations and to explore policy recommendations for improving their compliance based on a survey of 54 tanneries in Hanoi, Quangnam and Hochiminh city. The results showed that medium-sized and large tanneries responded positively to environmental regulations while none of the small household tanneries surveyed were found to comply. The main reasons for the latter’s non-compliance were found to be the lack of technical and financial capacity. Nonetheless, the compliance rate of tanneries in general was found to be much higher than that of other industrial sectors in Vietnam. Inspections, production capacity, location of firms, and type of tannery were found to be significant factors affecting compliance. Raising the penalties for non-compliance, increasing monitoring activities to detect offenders, and employing a multi-stakeholder and collective action approach were seen as possible strategies to bring about the greening of the tanning industry.

 Abstract Generally speaking, media is extensively used as the means to disseminate news and information pertaining to business, social, political and religious concerns. A portion of the time and space of media has now become an important device to generate economic and social activities that include advertising, marketing, recreation and entertainment. The Government regards them as an essential form of relaying news and information to its citizens and at the same time utilizes them as a powerful public relations’ mechanism. The effects of media are many and diverse, which can either be short or long term depending on the news and information. The effects of media can be found on various fronts, ranging from the political, economic and social, to even religious spheres. Some of the negative effects arising from the media are cultural and social influences, crimes and violence, sexual obscenities and pornography as well as liberalistic and extreme ideologies. This paper sheds light on these issues and draws principles from Islam to overcome them. Islam as revealed to humanity contains the necessary guidelines to nurture and mould the personality of individuals and shape them into good servants. Key Words: Media, Negative Effects, Means, Islam and Principles.

BACKGROUND In the span of COVID-19, the mortality rate has been different from one country to another. As a country in the Middle East Iraq has a critical position, lies between Iran and Turkey while both countries coronavirus cases increase on daily basis, while Iranian mortality rate record is high similar to Turkey. After Wuhan city of China, Lombard of Italy, Qum city in Iran has the highest number of COVID-19 as a first country in the Middle East. OBJECTIVE aim of this study is to show the effect of BCG vaccine during pandemic diseases, especially nowadays at the time of COVID-19. One of the crucial observations is the government preparedness and strategic planning prior pandemics, in which the BCG vaccine is an attenuated live vaccine for control of tuberculosis (TB). BCG vaccine has a non-specific immune effect that is used against pathogens like bacteria and viruses, through the promotion of pro-inflammatory cytokines' secretion. METHODS An epidemiological study has been performed, and it shows that some countries are more prone to contagious diseases like COVID-19, regardless of the main cultural, religious, societal similarities among the three mentioned countries. The information data has been collected from WHO reports and worldometer in 18 February 2020 to 10 May 2020. Regarding the efficacy of the BCG vaccine, relevant data has been retrieved from Google scholar, Pub-med and BCG world-atlas. RESULTS COVID-19 mortality rates are at peak in Iran and Turkey while the mortality rate is very low in Iraq, while the patients that died in Iraq all had history of other long-term diseases as heart disease, blood pressure, cancer etc. CONCLUSIONS From the experiences of the three countries in the life span of COVID-19, the historical plan of BCG vaccine in Iraq in cooperation with WHO since the last decades it shows that COVID-19 mortality rate is lower than other countries due to the early vaccination of the Iraqis, otherwise Iraq is more fragile than Iran and Turkey due to the poor conditions of Iraq in terms of economics, politics, war and other aspects.

BACKGROUND Rural physician undersupply is a universal concern, leading to sudden physician absenteeism or unavailability on occasion. While media and social networking services may help mitigate these emergencies, information is lacking about their actual contribution in times of physician absenteeism. On December 30, 2016, the director and sole physician of Takano Hospital in Fukushima, Japan, died. The physician’s passing placed many hospitalized patients in danger. This sudden case of physician unavailability, named the Takano Hospital Crisis, provoked massive attention from the general public, in the media and on social media networks such as Twitter. OBJECTIVE The aim of this study was to analyze newspaper articles, tweets and Twitter accounts relating to Takano Hospital Crisis. METHODS Newspaper articles and tweets were searched for keywords associated with Takano Hospital Crisis and its former director between October 2016 and June 2017. We first evaluated the chronological change in the number of articles and tweets, and the number of characters and relevant keywords in the articles. Then tweets and influencers who were popular on the Twitter platform from December 30, 2016 to February 28, 2017, were categorized. RESULTS We assessed 151 newspaper articles and 67,006 tweets. The results show that number of newspaper articles and tweets steeply increased and then diminished within the first month of the incident. The median number of characters in newspapers articles was 436 and the most frequent keyword was medical doctor. There were 753 original tweets that were retweeted more than four times from December 30, 2016 to February 28, 2017. Of these, 245 (32.5%) expressed concern. Notable influencers were journalists, news media outlets, and healthcare professionals that helped with fund raising and providing clinical service in the hospital. CONCLUSIONS Twitter could temporarily function in cases of sudden physician absenteeism to attract volunteers and funding, however, this would not be a long-term solution. In a more general context, a long-term effort of supports from the hospitals themselves and the government will be required to manage the persistent state of physician absenteeism.

Two low-level armed conflicts, Indonesia’s East Timor and Ivory Coast’s post-2010 election crises, provide detailed qualitative evidence of highly structured intergovernmental organizations (IGOs) engaging in effective civil warpreventing activities in member-states. Highly structured IGOs threatened and sanctioned each of these states and offered (long-term) benefits conditional on successful crisis resolution. The governments were aware of and responded to these IGOs’ concerns, as did the rebels in these respective cases. The early stages of the conflict in Syria in 2011 provide a counterpoint. With Syria’s limited engagement in only few highly structured IGOs, the Syrian government ignored international calls for peace. And, without highly structured IGOs’ counterweight to curtail the government, the rebels saw little reason to stop their armed resistance. The result was a brutal and deadly civil war that continues today.

As for the academics and policymakers, more attention has been given to the issue on how to reduce environmental pollution through the cooperation of environmental regulation and local officials’ promotion incentives. With the use of a city-level panel data of 266 Chinese cities from 2005 to 2016, this study preliminary explores the impacts of environmental regulations, local officials’ promotion incentives, and their interaction terms on urban environmental pollution at national and regional levels by using the spatial Durbin model. The results indicate that the impacts of environmental regulations and local officials’ promotion incentives on urban environmental pollution have achieved the desired goal with the other’s cooperation, and their interaction term’s coefficients on urban environmental pollution are significantly negative. Moreover, spatial heterogeneity is established, and the uneven development of urban environmental pollution among different regions deserves more attention. In order to effectively reduce the level of urban environmental pollution in China, the government should focus on such solutions as enhancing the implementation and supervision efficiency of environmental regulation, optimizing the performance appraisal system of local officials, improving the synergistic effects of environmental regulations and local officials’ promotion incentives, and establishing a multi-scale spatial cooperation mechanism based on both geographical and economic correlations.

Improving the livelihoods of communities living in fragile ecosystems, such as tropical forests, is among the main strategies to promote their conservation and preserve wildlife. In the Ecuadorian Amazon, farmers’ cooperatives are recognized as an important mechanism to improve the socioeconomic conditions of local communities. This study analyzes the integration of pyrolysis processes to convert agricultural waste into biochar as a way to implement the bioeconomy in these organizations. We found that post-harvesting processes in the studied farmers’ cooperatives are similar, and coffee husks are a potential feedstock to produce biochar. Although the environmental policies in Ecuador consider the valorization of agricultural waste, we did not find any specific standard to regulate the operation of pyrolysis facilities. Nonetheless, conversion of agricultural waste into biochar can contribute to (i) replacement of subsidized fossil fuels used in drying processes, (ii) prevention of environmental pollution caused by accumulation of waste, (iii) emergence of new income sources linked with the provision of carbon sequestration services, and (iv) the long-term maintenance of soil fertility. Currently, demonstration projects are needed to stimulate collaboration among farmers’ cooperatives, academia, the government, international cooperation agencies, and existing forest conservation initiatives.

Research on flourishing public bike-sharing systems has been widely discussed in recent years. In these studies, many existing works focus on accurately predicting individual stations in a short time. This work, therefore, aims to predict long-term bike rental/drop-off demands at given bike station locations in the expansion areas. The real-world bike stations are mainly built-in batches for expansion areas. To address the problem, we propose LDA (Long-Term Demand Advisor), a framework to estimate the long-term characteristics of newly established stations. In LDA, several engineering strategies are proposed to extract discriminative and representative features for long-term demands. Moreover, for original and newly established stations, we propose several feature extraction methods and an algorithm to model the correlations between urban dynamics and long-term demands. Our work is the first to address the long-term demand of new stations, providing the government with a tool to pre-evaluate the bike flow of new stations before deployment; this can avoid wasting resources such as personnel expense or budget. We evaluate real-world data from New York City’s bike-sharing system, and show that our LDA framework outperforms baseline approaches.

The government of Afghanistan promotes saffron production as a means to achieve economic development while reducing the widely spread opium cultivation in the country by providing necessary support to its farmers via saffron farmer service centers. This study investigates the causal effects of relevant attributes of potential saffron production promotion policies on the participation probabilities of saffron farmers. This study applies a randomized conjoint experiment to primary survey data of 298 farmers in Herat Province, which is perceived by the government as the center of saffron production in the country. The proposed hypothetical saffron production promotion policy consists of six attributes, namely, provision of machinery equipment, weather-based crop insurance, accessibility to long-term loans, location of saffron farmer service centers, provider of services, and annual payment. In the randomized conjoint experiment design, the respondents rank two alternative policies and policies against the status quo. The desirable policy comprises the machinery provision, long-term (up to 5 years) loan accessibility, an easily accessible service center, and policy implementation by international non-governmental organizations (NGOs). The estimated results reveal that saffron farmers are highly supportive of the proposed saffron promotion policy and that their willingness to pay is as high as 17% of their per capita income.

Focusing on Italy's Middle East policies under the second Berlusconi (2001–2006) and the second Prodi (2006–2008) governments, this article assesses the manner and extent to which the observed foreign policy shifts between the two governments can be explained in terms of the rebalancing between a ‘Europeanist’ and a transatlantic orientation. Arguing that Rome's policy towards the Middle East hinges less on Italy's specific interests and objectives in the region and more on whether the preference of the government in power is to foster closer ties to the United States or concentrate on the European Union, the analysis highlights how these swings of the pendulum along the EU–US axis are inextricably linked to a number of underlying structural weaknesses of Rome's foreign policy. In particular, the oscillations can be explained by the prevalence of short-term political (and domestic) considerations and the absence of long-term, substantive political strategies, or, in short, by the phenomenon of ‘politics without policy’ that often characterises Italy's foreign policy.
