Assessment of Municipal Solid Waste Management in the Farmgate Area of Dhaka North City Corporation

This investigation is focused on conducting a thorough analysis of Municipal Solid Waste Management (MSWM). MSWM encompasses a range of interdisciplinary measures that govern the various stages involved in managing unwanted or non-utilizable solid materials, commonly known as rubbish, trash, junk, refuse, and garbage. These stages include generation, storage, collection, recycling, transportation, handling, disposal, and monitoring. The waste materials mentioned in this context exhibit a wide range of items, such as organic waste from food and vegetables, paper, plastic, polyethylene, iron, tin cans, deceased animals, byproducts from demolition activities, manure, and various other discarded materials. This study aims to provide insights into the possibilities of enhancing solid waste management in the Farmgate area of Dhaka North City Corporation (DNCC). To accomplish this objective, the research examines the conventional waste management methods employed in this area. It conducts extensive field surveys, collecting valuable data through interviews with local residents and key individuals involved in waste management, such as waste collectors, dealers, intermediate dealers, recyclers, and shopkeepers. The results indicate that significant amounts of distinct waste categories are produced daily. These include food and vegetable waste, which amount to 52.1 tons/day;polythene and plastic, which total 4.5 tons/day;metal and tin-can waste, which amounts to 1.4 tons/day;and paper waste, which totals 5.9 tons/day. This study highlights the significance of promoting environmental consciousness to effectively shape the attitudes of urban residents toward waste disposal and management. It emphasizes the need for collaboration between authorities and researchers to improve the current waste management system.

Data Scale, Data Scope and Platform Enterprise Performance: Insights from Digital Platform M&As

Data is a key asset for digital platforms,and mergers and acquisitions(M&As)are an important way for platform enterprises to acquire it.The types of data obtained from intra-industry and cross-sector M&As differ,as does the extent to which they interact within or between platforms.The impact of such data on corporate market performance is an important question to consider when selecting strategies for digital platform M&As.Based on our research on advertising-driven platforms,we developed a two-stage Hotelling game model for comparing the market performance effects of intra-industry M&As and cross-sector M&As for digital platforms.We carried out an empirical test using relevant data from advertising-driven digital platforms between 2009 and 2021,as well as a case study on Baidu’s M&A activities.Our research discovered that intra-industry M&As driven by“data economies of scale”and cross-sector M&As driven by“data economies of scope”are both beneficial to the market performance of platform enterprises.Intra-industry M&As have a more significant positive effect on the market performance of platform enterprises because the same types of data are easier to integrate and develop the“network effect of data scale”.From a data factor perspective,this paper reveals the inherent economic logic by which different types of M&As influence the market performance of digital platforms,as well as policymaking recommendations for all digital platforms to select M&A strategies based on data scale,data scope,and the network effect of data.

From Differential Mode of Association to Tianxia Worldview:A Study on Chinese Entrepreneurial Spirit

China has made significant strides in economic and social development since reform and opening up over the past four decades.This process has been influenced by the exceptional innovation and entrepreneurship of Chinese business leaders,as well as their profound sentiments of compassion for the world and their country.It is of great significance to foster and promote an entrepreneurial spirit with distinctive Chinese characteristics.Not only is such spirit essential to the high-quality development of enterprises and the economy,but it is also a critical impetus for achieving Chinese modernization.Nevertheless,there is still a paucity of adequate theoretical discourse on the cultural origins and entrepreneurial spirit of outstanding Chinese business leaders.This paper employs the classical grounded theory method to conduct a 10-year follow-up research on 11 representative entrepreneurs and their enterprises.The results indicate that these entrepreneurs exhibit an evolving worldview along the paths of“self-cultivation and moral conduct”,“assisting employees to achieve”,“multilateral symbiosis”,and“the oneness of existence”when interacting with themselves,employees,partners,the general public,and all things in nature.Such entrepreneurial spirit is embodied in this paper as the“Tianxia(all-under-heaven)worldview”.Through theoretical construction,this study defines the concept of“Tianxia worldview”and extensively examines the distinctions and connections between the broadminded“Tianxia worldview”and the kinship-centered“differential mode of association”in terms of internal structure,value orientation,and applicable groups.It is posited that the transition from the former to the latter is a continuous process of transcendence and evolution of the individual mindset.This study has theoretical significance in the context of advancing the research on the Chinese entrepreneurial spirit,transcending the constraints of the management approach based on the“differential mode of association”,and enhancing the research on social responsibility from the perspective of“benefit corporations”.It also has practical value in overcoming the trust dilemma and development impediment of family businesses,ensuring that enterprises consciously fulfill their social responsibilities in a broader social context,and achieving common prosperity and progress for both enterprises and society.

地区空气污染的“压力”与企业绿色转型的“动力”——基于城市PM2.5和公司并购的实证发现

地区空气污染会影响域内各类市场主体行为,包括微观企业决策。碳达峰、碳中和的提出要求各地加强空气污染治理,推动企业绿色转型,而绿色并购是企业绿色转型的重要方式。利用2013—2018年我国A股上市的污染企业发起的并购为样本,并手动搜集整理确定绿色并购样本,实证研究地区空气污染对域内企业绿色转型的影响。研究发现,地区空气污染加剧会提升域内污染企业绿色并购的意愿。在此基础上,通过并购前后企业信息披露质量和社会责任承担变化,研究发现地区空气污染加剧下的企业绿色转型并非源于自主绿色转型发展的内生“动力”,更多是外部“压力”下的“工具主义”行为。从影响路径来看,地区空气污染引致的压力会通过行业竞争和融资约束这两个途径影响污染企业绿色转型的“动力”。最后,异质性检验发现在市场化程度高和非国有企业样本,地区空气污染加剧对企业绿色并购的促进作用更为显著。

随着云计算、大数据、人工智能等数字科技蓬勃发展,数字化创新深刻影响着企业创新与运营模式。利用结构方程模型(SEM)与模糊集定性比较分析方法(fsQCA)分析技术不确定性、市场不确定性、企业家精神、组织学习、组织忘记对企业数字化创新的影响。结果发现:技术不确定性、市场不确定性、企业家精神、组织学习、组织忘记和数字化创新6个要素存在因果线性关系,并发现学习主导型、市场驱动学习型和市场主导型3条数字化创新路径,以及3条非高数字化创新路径。其中,市场驱动学习型最有可能激发数字化创新。结合结构方程模型(SEM)分析结果,比较上述6条路径发现,数字化创新的影响因素具有非对称性,3条非高数字化创新路径并不是3条高数字化创新路径的对立面。

Correction of Corporation Value Assessment Model Based on Corporate Social Responsibility

The performance of corporate social responsibility is conducive to the con- tinuous improvement of their profitability, and promotes the upgrading of corporation value. However, it is difficult to confirm, calculate and check the costs and benefits brought by the implementation of corporate social responsibility under the current ac- counting theory system, so it is difficult to estimate whether the fulfillment of corpo- rate social responsibility has any effects on the corporation value assessment. Therefore, based on corporate social responsibility, the correction mode of corpora- tion value assessment is put forward.

Research on Corporate Social Responsibility Evaluation Based on Improved CRITIC-TOPSIS—A Case Study of Listed Companies in China’s Pharmaceutical Distribution Industry

Corporate social responsibility (CSR) has garnered considerable attention from countries, institutions, enterprises and social groups. However, the lack of research on CSR evaluation system for industries has impeded its development and construction across various industries. Therefore, given the close association of pharmaceutical distribution enterprises with personal health, there exists a pressing need to explore the CSR in this domain. This paper establishes a CSR evaluation index system for pharmaceutical distribution enterprises, employing a combination of documentary analysis and in-depth interviews. This index system comprises 7 CSR criterion layers (e.g., responsible governance and employee responsibility) and 56 index layers. 25 listed companies in China’s pharmaceutical distribution industry are chosen as research objects, and this study also establishes an evaluation model for the CSR of pharmaceutical distribution companies through the improved Criteria Importance Though Intercrieria Correlation (CRITIC) method combined with The Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. The empirical analysis reveals that the responsible governance criterion layer and the social development criterion layer demonstrate the best performance, while the supplier, customer and patient responsibility criterion layer exhibit the worst performance.

A scenario-based clean diesel production strategy for China National Petroleum Corporation

Facing increasingly strict environmental regulations on transportation fuels, China National Petroleum Corporation （CNPC）, the second largest supplier of petroleum products in China, needs to upgrade its transportation fuels. Using the scenario-based analysis method, this paper analyzes how the output and emission related properties, including cetane number, and sulfur and aromatics contents of diesel produced by CNPC, will vary with changes in the configuration of diesel production units in the next 5-10 years. The results showed that, to upgrade its diesel, CNPC needs to adjust its diesel pool by decreasing the share of fluid catalytic cracking （FCC） diesel and increasing the shares of hydrocracking （HDC） and hydrotreating （HDT） diesel. Furthermore, to produce ultra-low-sulfur diesel, straight-run diesel as well as poor diesel blendstocks such as FCC diesel and coker diesel should be hydrotreated before being blended into finished diesel. Developing highly efficient HDC and HDT catalysts and corresponding processes is the key to CNPC economically producing more and cleaner diesel.

A scenario-based clean gasoline production strategy for China National Petroleum Corporation

Facing increasingly strict environmental regulations on transportation fuels, China National Petroleum Corp. （CNPC）, the second largest supplier of petroleum products in China, needs to upgrade its transportation fuels. Using the scenario-based analysis method, this paper analyzes how the emission related properties, including antiknock index, and sulfur, olefin, benzene and aromatics contents of gasoline produced by CNPC, vary with the change in the configuration of gasoline production units in the future 5-15 years. The results showed that for CNPC to upgrade its gasoline, the share of fluid catalytic cracking （FCC） naphtha must be reduced, but just increasing reformate or alkylate and isomerate will result in excessive increase in benzene and aromatics contents or a great loss of gasoline octane number. Therefore, CNPC should suitably control the capacity of its FCC units and increase the capacity of reformer, alkylation and isomerization units. Most importantly, CNPC should dramatically expand the capacity of its hydrotreating or non-hydrotreating gasoline upgrading units to decrease the olefin and sulfur contents in FCC gasoline that takes a dominant share of about 80% in the gasoline pool of China.

Adapting Business of Energy Corporations to Macro-Policies Aiming at a Sustainable Economy. The Case for New Powering of Automobiles

A portfolio of new energy technologies has emerged in the first decade of the 21st Century, and many of them could be used for re-structuring the energy sector towards Sustainable Development. A key subject in this quest is the future of automobile, with possibilities on powering ranging from biofuels to Hydrogen Cars (HC), to Electric Vehicles (EV). In turn, the latter is closely connected with the need to deploy Renewable Energies (RE) for electricity generation. Within such new situation, countries and governments are aware that there are new tools for fighting Global Warming (GW), and new policies could be established for winning this battle against CO2. All these initiatives will affect the future of energy corporations, notably hydrocarbon companies;and it should be noted that it will be difficult for the companies to define long-term strategies if energy policies convey upheavals, sudden changes in promoting alternatives and interruptions on activities. Hence, it is very important to adopt energy policies allowing a smooth evolution of the companies’ activities to the new energy model. After analyzing the alternatives with a forecasting-backcasting methodology, an “eclectic approach” is proposed, with the Plug-in Hybrid car with Flexible Fuel (PiHFF) as the central paradigm in the coming promoting policies.

Computer controlled measurement of spontaneous combustion in coal stockpiles of the Western Lignite Corporation, Turkey

The spontaneous combustion event in coal stockpiles is inevitable when appropriate environmental conditions are available. The objective of a computerized measurement system is to measure temperature changes existing in a coal stockpile. In order to achieve this intention, the electrical signal conversion of temperatures sensed by 20 temperature sensors placed in certain points inside the coal stockpile, the transfer of these electrical signals into computer media by using analogue-digital conversion unit after applying necessary filterization and upgrading processes and the record of these information into a database in particular time intervals are provided. Afterwards, the diagrams of these time-temperature data are plotted. With the help of these graphs, the competent company will be able to examine the behavior of coal stockpiles in terms of spontaneous combustion and take necessary precautions against self-combustion beforehand.

Prevalence of Cesarean Section at Georgetown Public Hospital Corporation, Guyana: An Institution-Based Cross-Sectional Study

The International Healthcare Community recommends that countries do not exceed a 15% rate for cesarean section (CS). Our objective was to determine the prevalence and factors associated with CS at GPHC from July to September 2022. Methods: A cross-sectional study was carried out and data were collected from 1296 mothers, who met the inclusion criteria, through face-to-face interviews after obtaining prior informed consent. We performed descriptive analyses both for the outcome and independent variables. Bivariate and multiple logistic regression were used to identify factors associated with CS with a p-value Results: The prevalence of CS at GPHC was 28.9% (95%CI: 26.5-31.5). Factors associated factors with CS were mothers aged 20 to 34 years (AOR: 1.56, 95%CI: 1.02 - 2.39, P = 0.039);mothers who received more than three minimum wages (AOR: 1.95, 95%CI: 1.29 - 2.97, P = 0.002) and who attended prenatal care at both public and private health facilities (AOR: 2.49, 95% CI: 1.19 - 5.22, P = 0.022). Likewise, the highest Odds of CS were observed in mothers with gestational hypertension (AOR: 2.00, 95%CI: 1.35 - 2.96, P Conclusion: The prevalence of CS is higher than the ideal rate recommended by the International Healthcare Community. More studies are needed to understand the reasons for such high prevalence at GPHC.

Female directors in the boardroom and intellectual capital performance:Does the“critical mass”matter?

This research aims to investigate the influence of female directors on Intellectual Capital Performance(ICP)using a sample of manufacturing-listed companies in China.Our study investigates the link between having two or more female directors and the Modified Value-Added Intellectual Coefficient(MVAIC)methodology,employing the critical mass theory from 2004–2017.We find that having a critical mass of female directors(three or more)shows a significant positive impact on MVAIC and its components,including human capital efficiency,structural capital efficiency,relational capital efficiency,and physical capital efficiency,with physical capital being the critical driver.Our study reveals that the critical mass participation of female directors substantially influences the IC efficiency of privately owned companies compared to state-owned companies.Moreover,the number of female directors also affects the IC performance of manufacturing companies in multiple regions.Our findings support the validity of group classification identified by Kanter and Critical Mass Theory.To the best of our knowledge,this is one of the few pieces of research that studies the role of female board directors in IC performance and Chinese manufacturing firms using MVAIC as an IC measure.

Practice and Outlook of China's Regulation on the Extraterritorial Human Rights Responsibilities of Transnational Corporations

As China’s overseas investment and business operations continue to expand,the issue of human rights risks faced by Chinese transnational corporations abroad has attracted sustained attention from society.In recent years,China has enacted a series of laws,regulations,and policies to better regulate the overseas business conduct of transnational corporations,urging them to respect the human rights of the people in host countries and fulfill their social responsibilities to achieve sustainable development.Meanwhile,China has actively participated in the formulation of the Legally Binding Instrument on Activities of Transnational Corporations and Other Business Enterprises in International Human Rights Law,providing a Chinese solution to promote global governance of transnational corporations.However,in practice,the lack of institutional mechanisms,systems,and industry rules to supervise and guide transnational enterprises in fulfilling their human rights responsibilities,as well as the limited awareness of human rights risks among these enterprises,have resulted in ongoing human rights risks in their overseas business operations,particularly regarding labor rights and environmental rights.In response,China should take its national conditions into consideration and focus on the development trends of human rights issues in the business sector at the international level.Drawing on the experiences of other countries,China should explore and establish institutional and practical measures to regulate the human rights responsibilities of transnational enterprises through legislation,administration,and judiciary actions,in order to address the risks and challenges faced by Chinese enterprises in foreign investments and contribute to the sustainable development of the world and global human rights governance.

Left atrium veno-arterial extra corporeal membrane oxygenation as temporary mechanical support for cardiogenic shock:A case report

BACKGROUND Veno-arterial extra corporeal membrane oxygenation(VA-ECMO)support is commonly complicated with left ventricle(LV)distension in patients with cardiogenic shock.We resolved this problem by transeptally converting VAECMO to left atrium veno-arterial(LAVA)-ECMO that functioned as a temporary paracorporeal left ventricular assist device to resolve LV distension.In our case LAVA-ECMO was also functioning as a bridge-to-transplant device,a technique that has been scarcely reported in the literature.CASE SUMMARY A 65 year-old man suffered from acute myocardial injury that required percutaneous stents.Less than two weeks later,noncompliance to antiplatelet therapy led to stent thrombosis,cardiogenic shock,and cardiac arrest.Femorofemoral VA-ECMO support was started,and the patient underwent a second coronary angiography with re-stenting and intra-aortic balloon pump placement.The VA-ECMO support was complicated by left ventricular distension which we resolved via LAVA-ECMO.Unfortunately,episodes of bleeding and sepsis complicated the clinical picture and the patient passed away 27 d after initiating VA-ECMO.CONCLUSION This clinical case demonstrates that LAVA-ECMO is a viable strategy to unload the LV without another invasive percutaneous or surgical procedure.We also demonstrate that LAVA-ECMO can also be weaned to a left ventricular assist device system.A benefit of this technique is that the procedure is potentially reversible,should the patient require VA-ECMO support again.A transeptal LV venting approach like LAVA-ECMO may be indicated over ImpellaTM in cases where less LV unloading is required and where a restrictive myocardium could cause LV suctioning.Left ventricular over-distention is a well-known complication of peripheral VA-ECMO in cardiogenic shock and LAVA ECMO through transeptal cannulation offers a novel and safe approach for treating LV overloading,without the need of an additional percutaneous access.

Impact of sustainability on financial distress in the air transport industry:the moderating effect of Asia–Pacific

The tremendous impact of the coronavirus pandemic on the global aviation industry has led to many cases of airline financial distress and bankruptcy.The Asia–Pacific region(APAC)contains more than half of the world’s population,and its airlines had the highest profit margin of any region.In this study,we investigate whether corporate sustainability practice can reduce the financial distress risk of air carriers,and,if so,what would the effect be in APAC?We first examine the relationship between environmental,social,and governance disclosure and the likelihood of financial distress of airlines as measured by the Altman Z″-score.Second,we analyze the moderating role of being an APAC airline in this relationship.The findings support the claim that implementing environmental actions may increase financial distress risk,and by improving social and governance activities,airlines can mitigate the risk of financial distress.The negative influence of the environmental pillar and the positive influence of the social pillar can be smaller for APAC airlines.Our study provides empirical evidence of the influence of environmental,social,and governance(ESG)on the likelihood of financial distress in the airline industry.Moreover,we analyze the moderating role of being an APAC airline in the relationship between sustainability and financial distress.This study has significant implications for executives,managers,and policymakers in the aviation industry on ESG strategy decisions and the general issue of sustainability.

Do companies influenced by smart cities pay more attention to green governance?Mechanism and optimal spatial correlation

Smart cities are a way for China to construct an innovative and environmentally conscious nation.The paper examines the impact of smart cities on corporate green governance and provides a theoretical foundation for formulating and executing smart city policy in China.Based on panel data from Chinese A-share listed companies in Shanghai and Shenzhen from 2008 to 2020,this study constructs a multiperiod double-difference model to examine the influence of smart cities on corporate green governance.Additionally,it uses a spatial double-difference model to investigate the spatial spillover effect of smart cities on neighboring areas.The findings indicate that smart cities effectively enhance corporate green governance.Analyzing the influencing mechanisms reveals that resource allocation efficiency,technological innovation,management environmental awareness,and regional environmental enforcement efforts act as mediators.Furthermore,the study reveals that the impact of smart cities on promoting corporate green governance is more pronounced in regions with lower levels of marketization and resource-based cities.Moreover,the research explores the spatial spillover effects of smart cities,with an effective radius of approximately 350 km.The optimal spatial correlation zone for green governance of businesses in neighboring areas in relation to smart cities is within a range of 250-350 km.This is manifested by the significant promotion of green governance in neighboring area businesses facilitated by smart cities.
