In this paper, a stochastic model of a closed-loop supply chain (CLSC) with one risk-averse manufacturer, one risk-averse retailer and one risk-averse third party is developed. To analyze how the members make decisions about wholesale price, collection rate, retail price and sales effort under different decision-making structures, the optimal decision problem under uncertain price and sales effort-dependent demand is studied through development of four game theoretical models. The equilibrium results between various models are compared and the optimal decisions from each member’s perspective are investigated. According to the results, the third party-led model has better performance than manufacturer-led model. The cooperation mode of manufacturer and retailer is beneficial for the whole chain and customers and the cooperation mode of manufacturer and third party is the most effective model to collect the used-product. Finally, to increase the performance of decentralized CLSC compared with the centralized CLSC, a coordination contract is developed. The results indicate that this contract is advantageous for the members of CLSC, the customers, and the environmental issues.

Permutation flow shop scheduling problems have been an interesting area of research for over six decades. Out of the several parameters, minimization of makespan has been studied much over the years. The problems are widely regarded as NP-Complete if the number of machines is more than three. As the computation time grows exponentially with respect to the problem size, heuristics and meta-heuristics have been proposed by many authors that give reasonably accurate and acceptable results. The NEH algorithm proposed in 1983 is still considered as one of the best simple, constructive heuristics for the minimization of makespan. This paper analyses the powerful job insertion technique used by NEH algorithm and proposes seven new variants, the complexity level remains same. 120 numbers of problem instances proposed by Taillard have been used for the purpose of validating the algorithms. Out of the seven, three produce better results than the original NEH algorithm.

This study aimed at testing the potential impact of the disclosure of the main variables of sustainable development on the quality of financial reports, in a developing country, Iraq, where there is a lack of research in this area. To achieve its goal this study relied on an analysis of a sample from 91 financial reports of the Iraqi commercial banks listed on the Iraq Stock Exchange during the period 2012-2018. Our results prove that disclosure of the dimensions of sustainable development as a whole has a positive impact on the quality of financial reports in commercial banks in Iraq. The paper recommends conducting more research and studies on the dimensions of sustainable development in the future for other sectors such as industrial and service sectors linking it with other variables such as the cost of capital, or inconsistency of information.

E-commerce market of Pakistan is instable which causes low performance of e-logistic industry. Thus, logistic industry of Pakistan is lacking as compared to other developing countries such as China, India, and Malaysia. Low performance is majorly based on low staff service quality, inappropriate website design and goods traceability system. As remedies of these issues, the current study introduced firm’s IT capability and information communication technology (ICT). The primary objective of this study is to investigate the determinants of e-logistic firm’s performance in Pakistan. To achieve this objective, quantitative research approach along with cross-sectional research design was used. By using the survey method, 300 questionnaires were distributed among the managerial staff of e-logistic companies. Smart PLS 3 was used as a statistical tool. It is found that staff service quality, website design and e-traceability had significant and positive relationships with firm’s e-logistic performance. Moreover, firm’s IT capability as a moderator enhanced the positive effect of staff service quality, website design and e-traceability. Nevertheless, information communication technology (ICT) positively mediated the relationship between e-traceability and firm’s e-logistic performance. Hence, firm’s IT capability and information communication technology (ICT) are the key elements to decrease various issues of staff service quality, website design and e-traceability. The study is much significant for practitioners and e-logistic companies to enhance performance by focusing on firm’s IT capability and information communication technology (ICT).

It was found that earnings per share and dividend yield had a positive and significant relationship with share prices, while book value had a negative one.

The influence of military-political instability at the state security has special consequences and cannot be ignored. That is why the methods of economic security calculations should be adapted to modern conditions. Significant changes in economic, political, social conditions in Ukraine because of the influence of military events cause the necessity of developing approaches to calculations of economic security level. The article aims at analyzing active methods of calculations of economic security level to adapt their indicators to actual economic circumstances in Ukraine and the world. Indicators of the economic security have been composed of budget, money-credit, foreign exchange, debt, known banking financial market security, banking security. Every component of economic security has factors of war influence, which, as a result, correlates with the integral indicator of economic security. The relevance and indispensability of reinforcement of the economy’s competitiveness on security foundations are substantiated. The authors’ methods of calculation of an integral indicator of economic security have been suggested. A taxonomic indicator is used to measure the level of security. Conclusions regarding the preconditions, capacity, and availability of tendencies of economic security in regions of the country have been made. Strategic priorities of the state policy for reinforcement of economic security have been substantiated.

Land acquisition and resettlement issues related to hydropower and irrigation works have always been one of the hot issues in Vietnam mountainous areas for many years. Although the Government has introduced many policies to ensure the rights of resettled people, as well as protect their lives, the effectiveness of these policies seems to be still insignificant, because many resettled people still face many difficulties in their daily life, especially income. The research is conducted within the project titled “The urgent issues in resettlement implementation for the ethnic minorities in Vietnam mountainous areas” and funded by National Council for Science and Technology Policy in 2016-2020 (CTDT/16-20) under Committee for Ethnic Minority Affairs. Applying Likert-scale and Propensity Score Matching (PSM), this study shows that 34% of the resettled households have a lower income, specifically estimated to be 8.0 - 13.1 million VND/household/year or 1.7 - 3.0 million VND/person/year lower than the income of the controlled group. However, agricultural income is not significantly different between resettled households and controlled households. This article only focuses on clarifying the impact of the resettlement policy on the general income and agricultural income of ethnic minority households; while methods to create jobs, increase income, and reduce poverty sustainably for ethnic minority households in the resettlement sites should be conducted in another research in the future.
