The urban waste transfer network plays an important role in urban life, and the site selection and route planning involved are not only research issues in the field of logistics systems, but also closely related to the field of social and people’s livelihood. In this paper, starting from the overview of the urban waste transfer network problem, a two-layer model of site selection and route optimization is constructed, and the genetic algorithm and the improved ant colony algorithm are used to study them respectively.

Purpose: The study aims to develop insights on the progress made in agreeing upon the set of macroeconomic factors be included in the arbitrage pricing theory (APT). Theoretical Framework: The paper is brief review of relevant literature focusing on studies that have tested different macroeconomic factors for possible relationship with stock returns. Design/Metho- dology/Approach: A brief overview of the literature was performed to determine the macroeconomic factors with a positive relationship with stock returns to be used in the APT from studies on the cost of capital evaluations. Findings: The article contributes to the relevant literature by showing that there is consensus on interest rate as the macroeconomic factor that strongly explains the relationship with stock returns. Other microeconomic factors such as inflation, exchange rates, money supply and industrial production showed strong prospects but require more tests. Research, Practical & Social Implications: The article identifies the macroeconomic factors that need further studies based on the prospects shown in the studies reviewed. Practically, the article contributes to narrowing the research gap on macroeconomic factors to be used in the APT. Originality/Value: The article adds value to the body of knowledge by showing that only interest rate has been agreed upon as the macroeconomic factor with a positive relationship with stock returns. The article also narrows the gap of the set of macroeconomic factors that need further testing thereby hastening the process leading to the use of the APT.

This article evaluated the total factor productivity of Ethiopian banks from 2011 to 2020 using the DEA-based Malmquist productivity index and one-step system GMM dynamic data approaches. The study covered the 14 banks that were operational during the study period and examined the regressive, stable, and progressive nature of their productivity taking into account both the production and intermediary role of banks. We used constant returns to scale to compare the efficiency and productivity and establish a benchmark for bank performance. Interest expense, operating non-interest expense, and deposits were used as input variables and interest income, operating non-interest income, and loan and advances as output variables to analyze the productivity change of banks in their production role while deposits and loans were used as input and output variables, respectively to study productivity change of banks in their intermediation role. The study concludes nominal efficiency change both due to improved operations and management practices as well as increased economies of scale and deterioration in technological efficiency. We also conclude nominal regress in total bank factor productivity during the study period and a regressive, and progressive impact of technology, and improved management practices on the productivity of Ethiopian banks, respectively. Consequently, we suggest a thorough feasibility study in the technology choice of banks.

Coffee farming sector is affected by two main factors; the coffee price at international market goes up and down depending on the current situation. On the other hands the cost of farms’ inputs changes up-down due to inflation and others related factors. These factors have a negative impact on profitability of coffee farming to the extent that some farmers are demotivated. There is therefore a need for an innovative solution to this problem. The coffee-based tourism is regarded as a growth niche tourism market and may come up with solutions to problems the coffee sector is facing. This paper’s main objectives are to assess the potential contribution of Coffee based tourism to the coffee sector, and to identify factors that may promote or hinder the coffee-based tourism development in Nyamasheke District. The study followed a qualitative research methodology. Data were collected through face-to-face interviews with ten Coffee Washing Stations managers, four farmers representing coffee farmers organizations and the District’s Vice Mayor of economic affairs. Respondents were selected purposively because are not only involved in the coffee farming business but are also interested in the development of the coffee sector. The study found that Coffee Based Tourism may contribute to the improvement of coffee production as it may motivate coffee farmers to improve their farming activities, improve the coffee farmers’ livelihood, and improve the coffee sector in Rwanda. The SWOT analysis presents factors that may promote or hinder the coffee-based tourism in that district. Strength and opportunities are the promoting factors, while weakness and treats depict the hindering factors. In addition, this paper concludes by arguing that the success of this new venture would depend heavily on the central government and the local government’s will through policy development and other supports needed to develop this business venture.

This study focus on understanding the relationship between strategic leadership and innovative performance. To test the theoretical model quantitative method was applied. This study was conducted on 345 white collar employees working in the manufacturing sector in Istanbul, Turkey. For the research, data collection method questionnaire application was implemented during May, June, July, and August in 2021. The survey response rate is 77%. As a result of the factor and correlation analysis there is positive and significant relationship between strategic leadership and innovative performance. According to correlation analysis transformational leadership (r = 0.712) and political leadership (r = 0.703) sub-dimensions have a higher correlation with innovative performance, managerial (r = 0.498) and ethical leadership (r = 0.543) have a positive relation with innovative performance as well. According to ANOVA test results, it was also found that there are differences in the perception of strategic leadership based on age level. Followers at 20 - 30 ages have higher strategic leadership perceptions than others.

The objective of this study was to test the impact of digital financial inclusion on trade openness using a panel of 16 African countries observed over a 17-year period from 2002 to 2018. T > N, this study favors a methodology based on static panel estimates using the generalized least squares (GLS) method. The results obtained revealed that only one variable (logGDP) out of the five retained has a statistically significant influence on trade openness at the 1% level (p > t = 0.06) with a coefficient opposite to the predicted sign of (﹣0.2371655). This coefficient shows that the decrease in national production in these countries by 0.23% leads to a decrease in the level of trade by 1%. In relation to the variable of interest (ATMs), it was found that it negatively and significantly influences trade openness at the 1% level. When the level of trade decreases by 0.6%, it means that the use of digital finance has decreased by 1%. Also, the study finds an R2 within of meaning 0.0527 that at 5.27% the fluctuations in trade in these economies are explained by the model variables.

In this paper we will discuss and analyze the existed situation in upcoming strong Greek ports, their development and the new opportunities that arise for investors. This study analyses the reforms and examines the port governance configurations and the reform process as it unfolded over the last 12 years until today’s tenders for sale majority stake and sub-concessions of the terminals. This discussion includes an examination of the background conditions (port sector developments, natural sources of energy, economic and political context) aiming to understand the foundations of the endorsed decisions and of the apparent delays to progress announced reform programs. The paper also discusses the evolution of the container ports and other ports in Greece, recording the increased market concentration that followed the concession of the Port of Piraeus terminal, as well as the different trends in other important Greek regional ports, like port of Alexandroupoli, Kavala, Patra, Igoumenitsa, Elefsina and Heraklion, as regards throughput, investments, and commercial relations, that were observed in the case of the privately operated container port.

The objective of this project is to produce knowledge about hybrid food systems positioned between short and long circuits, addressing their economic, social, and environmental performances and the conditions of their sustainability, to co-construct with project partners a method and support tools for their sustainable development. These systems are particularly complex, with interactions between actors, interactions between performance indicators of various kinds, new vocabulary and new practices centered on human relationships, with very little formalization. To tackle this problem, we propose a new system engineering approach based on meta-modeling to consider the flow, the requirements and performance indicators. After presenting the problem, we will detail our approach and its implementation. We will end with a review and perspectives.

The rapid rise of short video platform has created a broad platform for live delivery, which has become a very hot new way of shopping, so many businesses and individuals have brought goods and sold goods through various online live delivery platforms. However, some businesses sell fake and shoddy goods through live broadcasts without conscience. Based on the idea of game theory, this paper constructs a mixed strategy game model with the participation of the supervision department and merchants of short video platform, analyzes the Nash equilibrium of the mixed strategy of the game model, and further constructs a mixed strategy model with the participation of government regulators, short video platform regulators and merchants. It is found that the lower the supervision cost of short video platform and the higher the fine, the smaller the probability of merchants selling unqualified goods. The probability of strict supervision of short video platform is affected by the size of its fine; The lower the detection cost of government supervision department and the greater the reward for strict supervision of short video platform, the higher the probability of strict supervision of short video platform; The probability of random inspection by government supervision departments is influenced by its punishment, detection cost and strict supervision cost of short video platform.

Due to increasing digitalization, the German banking sector is undergoing a massive period of change. This threatening challenge is massively influenced by demographic change, supervision and regulation, the low-interest phase and technological progress. In the last twenty years, mergers of regional banks, staff reduction measures and the closure of their traditional bank branches have been the order of the day. Banks in Germany are therefore forced to deal with the introduction of omni-channel concepts. The aim of the research is to make a statement on the extent to which the two distribution channels “bank advisor” and “traditional bank branch” will still play an active role for regional banks in Germany in the future. The results of standardized interviews with bank experts (N = 43) in Germany form the core of this study. This paper summarizes the findings of the quantitative research descriptively. Furthermore, the article critically examines the academic discussion on the digital transformation of banks in Germany, especially savings and cooperative banks. This article is structured as follows: Introduction, Literature Review, Methodology, Results and Discussion, Conclusions, Limits and Directions for further Research. The results of this article can be useful for researchers and bank practitioners to identify and utilize the strategic change potential under omni-channel aspects due to the digital transformation.
