The effect of supply chain learning on flexibility performance: an empirical study
No full textToday’s intensely competitive business is undergoing significant shifts, which render it a challenging environment to compete in. Production processes are evolving as customer demands change, which leads to greater variability. Firms must respond to changing environmental conditions to remain sustainable. Companies today look for ways to overcome their problems not only on their own but also with their supply chains. Reduced cost and improved performance are two significant benefits of supply chain management. Because companies can work together in the face of challenging market conditions throughout their supply chains, it makes sense for them to collaborate. When companies work together, they can collaborate to produce better-designed products and more efficient manufacturing processes. Learning, supply chain integration, and flexibility throughout the supply chain are critical to successful supply chain management.
In this study, the effect of supply chain learning on supply chain integration and production flexibility has been investigated. The mediating role of supply chain integration on the impact of supply-chain learning on production flexibility has been tested. For this purpose, survey data was collected from the 144 companies selected out of Turkey's largest exporting companies. The data were analyzed via structural equation modeling and process macro methods. As a result of the structural equation model analysis, it was found that supply chain learning significantly affects the chain’s integration and its production flexibility. As a result of the intermediation test, it was determined that the integration of the supply chain has a vital intermediary role regarding the effect of supply chain learning on the flexibility of production

Modelling and simulation of charge transport phenomena in graphene on SiO2 / Si substrate and graphene on complex oxide substrates
Full text linkGraphene and silicon are two prominent lithium-ion battery anode materials that have recently received a lot of attention. In this paper we have modelled and simulated the charge transport phenomena in Graphene on Si / SiO2 and SrTiO3 substrates. The Graphene monolayer's interface with the SrTiO3 (111) surface is analyzed using ab initio density-functional measurements. Both charge and heat flows are produced in solids, at the same time when an electrochemical potential is available, bringing about novel properties. The band structure and the electron dissolution process decide the Seebeck coefficient and electrical conductivity. It has been discovered that the interaction of Graphene with SiTiO3 accommodates electronic properties, Seebeck coefficient, and electronic conductivity. For the Graphene / SrTiO3 interface, the best values for the Seebeck coefficient were calculated. All the findings of this work suggest that the Graphene-SrTiO3 (111) and Graphene-Si structure could exhibit interesting quantum transport behavior
An overview about multiple intelligences: a comparative study with business administration students of two private universities in southern Brazil
Full text linkExperts claim for more studies on Theory of Multiple Intelligences in higher education classrooms. There is a lack of information on the characteristics of multiple intelligence in universities in developing countries, such as Brazil, as they can assist in the education of students in a wide variety of fields. This study aims to analyze and compare the types of multiple intelligences among bachelor students of Business Administration programs in private universities. We conducted a quantitative study based on survey with students from two private universities in the southern Brazil. The results indicated that the academic profile of both programs has similarity in the average frequency of most of the identified intelligences. The intelligences identified that showed statistically significant differences between academics are: logical-mathematical, interpersonal, musical and naturalistic. In general, the most developed multiple intelligences are: logical-mathematical, interpersonal, intrapersonal and bodily-kinesthetic. In addition, the least developed are: spatial, linguistic, musical and naturalistic
Monetary policy and banking intermediation in CBDC economy
Full text linkIncreased dissemination of information and communication technologies in the economy has led many central bankers around the world to consider the introduction of money in the digital form. In academic literature, various central bank digital currency (CBDC) issues from technical design to political influence are discussed, although until now it has not been fully implemented in any country except the Bahamas. The central bank digital currency (CBDC) is an additional form of national currency that combines the properties of cash and bank accounts. This study mainly aims to provide a comprehensive analysis of monetary policy in the CBDC economy. to meet the aim of the study, the study applies an agent-based model that has six types of economic agents and complicated interaction algorithms. The various design parameters are employed to study the dynamics of endogenous variables. Model simulations suggest that CBDC introduction leads to reduced macroeconomic volatility and price stability. Furthermore, the study provides evidence of the increased efficiency of the interest rate channel of the monetary policy transmission mechanism and the negative consequences of possible banking disintermediation. Based on the results obtained, the study concludes that the CBDC impact the economy through changes in the monetary base, strengthening the structural liquidity deficit, banking disintermediation, and increasing the fiscal policy capabilities. The proposed agent-based model provides a theoretical foundation for the further study of monetary policy and banking intermediation in the CBDC economy
Rationale for the need to use blockchain technology to record and control operations for the export of grain (the example of Ukraine)
Full text linkDespite the steady export of Ukrainian grain growth, the net profit from its sales does not increase, and most times, even falls. That is why it became necessary to find out the reasons for the current situation and find ways out of it. The most common method for solving such problems in the modern world is the implementation of blockchain and related technologies (smart contracts, cryptocurrencies, etc.). This article is devoted to studying the economic need for the use of blockchain technologies to monitor grain for export in Ukraine and the analysis of foreign experience blockchain implementation to agricultural supply chains to adapt the best practices to Ukrainian realities. As a result of a theoretical study, the article identified problems in Ukrainian grain export, analyzed the results of using blockchain to solve similar problems in foreign countries, and also identified ways to use world experience in this area. In addition, the authors offered practical recommendations for changing and complementing the existing technological and logistic stages of grain export in Ukraine. It was also found that blockchain technologies, because of their properties such as decentralized control, security, traceability, and control of transactions, could solve most of the problems that arise in the grain supply chain from grower to end consumer. The authors have proposed a generalized multilayer system that includes a "Data input layer", a "Data store layer", and a "User's layer", which most fully considers the peculiarities of agriculture in Ukraine. However, the question of these technologies introducing cost and the economic feasibility of their use for farms of various sizes remains is still unclear, and will be considered by the authors in their following works
A Customer complaint from a telecommunication company: a Bayesian data analysis
Full text linkThis study considers a customer complaint dataset due to the technical services provided by a telecommunications company collected for 134 consecutive weeks from the first week of January 2018 up to the year 2019. The total count of weekly complaints is the sum of different causes, which characterizes compositional data. The data was analyzed assuming a Poisson regression model for the weekly total complaint count data in presence of a random factor and compositional models both under a Bayesian approach using existing MCMC (Monte Carlo Markov Chain) to get the posterior summaries of interest. The obtained results are of great importance to improve the service quality of the company
Analysis of industry 4.0 and their impact on port environmental management
Full text linkIndustry 4.0 (I4.0) is a reality in several business segments worldwide. Technologies (I4.0) collaborate to improve production processes, in manufacturing or in services. The use of these technologies in port operations for container handling can assist in environmental management and allows the service system to be sustainable. This research analyzed the use of technologies from I4.0, applied in port handling operations of containers, to verify their impact on environmental management. Some ports, of great international relevance, were searched for data collection regarding the use of I4.0 technologies and environmental management (port sustainability). These data were analyzed to understand the relationship between those technologies and sustainability in logistics operations (green operation). The focus of this study was to analyses some container terminal operations of five ports, to assess the use of I4.0 technologies and their impact, or not, on sustainable environmental management. The method of carrying out the research was the application of an online questionnaire to five Ports: Los Angeles (USA), Hamburg (Germany), Rotterdam (Netherlands), Singapore (Singapore) and Busan (South Korea) exclusively for container terminals. Public materials available on the websites of each port were also used. The questionnaire was developed by reviewing the literature on the topic (Digital Business – I4.0 and Sustainability – green operations). An online survey to collect information took place between September-2019 to June-2020, which was complemented with publicly accessible material on the internet. The collected data were treated statistically for analysis of the research information applied in the ports (mean, standard deviation, significance level, Kolmogorov-Smirnov Test, critical statistical value, correspondence analysis and relative frequency). Overall information was collected from 20 container terminals. Experts (managers and supervisors) responded the online survey
An ethics crisis and corporate failure in food and beverage companies. evidence from Zimbabwe
Full text linkLack of adherence to ethics and principles appears to have been one of the main causes of corporate financial distress around the world. A lot of unethical practices have contributed to revenue leakages and reluctance by investors to buy a stake in the industry. The prevalence of unethical practices, illegal behavior, illicit and deceptive practices in food and beverage companies is an unsolved issue. The aim of the research was to find out the effect of ethical problems on company’s financial performance in food and beverage industry. The high failure rate of brands in the food and beverage companies has given the researcher interest to investigate the impact of ethics on financial performance of a company. Due to the diverse nature of food and beverage industry, an action research inquiry of 20 interviews and 100 questionnaires was conducted. A mixed method convergent approach was used to analyse collected data using questionnaires and interviews. Findings from the study that there is strong positive relationship between ethical conduct of employees, managers, business conduct and the financial performance of food manufacturing company. The study results show that ethical branding significantly enhances the firm's reputation; and good reputation reinforces the brand in turn. Ethical branding can provide the company with a differential advantage as a growing number of consumers become more ethically conscious. It is therefore recommended that, ethical issues should be considered in all company departments and embedded into total quality management processes of an organization as it affect potential investors and customers
