This study aims to measure the overall technical efficiency score and analyze its determinants in the Vietnamese shipping industry. The data used in the study is the enterprise census data set collected by the General Statistics Office of Vietnam from 2016 to 2020. A major difference in this study compared to other empirical studies about the efficiency in Vietnam is that we applied the stochastic frontier analysis with four random components. The results of measuring efficiency scores show that: The average overall technical efficiency (OTE) score of Vietnamese shipping firms is 0.539. In which the persistent technical efficiency (PTE) score averaged 0.883 and the transitory technical efficiency (TTE) score averaged 0.60. It shows that the potential for operational efficiency of Vietnamese shipping firms is still very large. The results of the analysis of the determinants of OTE showed that. Internal firm characteristics such as firm size, firm age, return on equity of firm have a positive effect on OTE. And state-owned firms are less efficient than non-state firms. Besides, factors such as participation in international shipping, the quality of economic institutions also have a positive relationship with OTE. However, financial constraint, specifically the level of credit outstanding, is the main cause of slowing OTE growth.

To cope, preserve market position, and achieve sustainable competitive advantage (SCA), companies should put operations strategy into action systematically and coherently. In this vein, the purpose of this study is to evaluate small and medium-sized (SME) pharmaceutical firms in southern Vietnam considering their current strategic orientation, development path, and sustanability of competitive advantage. The method used in this research is Sense and Respond (S&R), supported with combination of different tools. The data has been gathered from six companies utilizing two questionnaires: “Manufacturing strategy index (MSI)” and “S&R”. The results show that, all case companies act as Analyzer both in the past and in the future when employing operations strategy. In all case companies, quality found to be the most important competitive priority in the past and future, and the main source of competitive advantage. Furthermore, spearhead technology and knowledge (T&K) found to be the main source of risk in operations strategy and SCA. The Weak Market Test demonstrates that the research results are consistent with the actual situations of the case companies. The research concludes that S&R method works well in evaluating the operative SCA of pharmaceutical SMEs.

Ports and terminals are directly related to world economic development due to international trade. In this sense, port management has expanded actions in terms of sustainability and mainly linked to circular economy (CE). The port environment is not alien to society's developments and for that it needs to improve its efficiency and operability, reducing the waste of time, processes and waste generated within it. In this context, this research links the Lean 4.0 concept with the circular economy as an alternative for the development of the port sector. The study is based on highlighting the challenges and advantages of implementing CE in ports through Lean 4.0. To achieve the objective of this research, a literature review was carried out based on the Sytematic Research Flow - SSF method proposed by Ferenhof and Fernandes (2016), followed by a content analysis based on Bardin (2011). Based on the findings, it was possible to list the key elements linked to Lean 4.0 correlated with the circular economy to stimulate the sustainability of the port sector. It was identified that Lean 4.0 presents itself as a simplifier for the implementation of the circular economy culture, since it enables the alignment of people to identify waste, stimulates innovation and the development of a culture aimed at continuous improvement in the sector.

According to the World Health Organization (WHO), health inequities refer to those dimensional, measurable, and avoidable differences between socially, economically, demographically, or geographically defined population groups. In Mexico, despite several advances in health services and infrastructure, there are health inequities in rural communities, particularly those with indigenous population. These communities have limited or non-existent healthcare facilities, medical equipment, transport infrastructure, medicines, and human resources such as doctors and nurses. In this work, a conceptual design of a healthcare network is proposed to serve a region with several rural communities with limited healthcare resources. The designed network allocates rural communities to the most appropriate facilities based on (a) a vulnerability community index, and (b) a facility service index. The application of the conceptual network led to a hierarchical referral scheme between communities and different types of healthcare facilities to improve medical services and infrastructure planning. These results can support the decisions aimed to expand already existent facilities, replace multiple basic facilities with an appropriate number of larger and more advanced facilities, and determine the transportation infrastructure required to reach these facilities.

The current research is to ascertain the effect of human resources (HR) policies and procedures on employees. The study is based on the quantitative method. The employees at the United Arab Emirates universities are the selected audience. Google Forms was used to disperse the survey, where 100 responses were collected in this study. The questionnaire adopted a Likert scale of seven points. Tests such as factor loading, internal consistency, Convergent Validity (AVE), Discriminant validity, Coefficient of determination (R2) and adjusted (R2), Path Coefficient (β), and t-test through ADANCO were conducted. This research shows that performance evaluation of all other variables, such as compensation, promotion practices, training and development, and employee involvement in decisions, has a really beneficial impact on PEP. The current research helps universities to plan the practices of HR and increase the PEP of their teachers. This is because it has the potential to provide professors, academic leaders, and supervisors with fresh perspectives that will aid in the spread of knowledge and the efficient operation of the academic workplace. Employee turnover in UAE government agencies is affected by management style and a lack of employee empowerment, according to the study. There were signs that workers' distaste for centralized leadership influenced their desire to remain with their current employers. Many research papers have been done on this topic in developed countries. However, none of these studies has been accomplished.

In today's manufacturing industry, digital transformation has become a focal point for academia and practitioners due to its potential to drive supply chain management and sustainability outcomes. This transformation provides numerous opportunities to improve strategic, tactical, and operational capabilities to meet sustainability goals. However, the high level of uncertainty associated with digital transformation programs has created doubts among many manufacturing companies about the successful adoption of digital transformation in their supply chain processes. While previous studies have examined digital transformation technologies and their implementations in supply chains, little attention has been given to the drivers and barriers associated with adopting digital technologies for sustainable supply chains, especially in the context of manufacturing. Therefore, this study aims to fill this gap by providing a comprehensive overview of digital transformation adoption in manufacturing supply chains and identifying the critical drivers and barriers to successful digital transformation implementation. A total of six barriers and eleven drivers have been selected from the literature. Finally, this study provides insights for decision-makers to overcome the main barriers that hinder the successful implementation of digital technologies in supply chain functions, which can lead to a higher ethical supply chain level from a sustainability and operational efficiency perspective.

One of the significant challenges that the world is confronting is road traffic accidents. The aim of this study is to determine the key factors contributing to traffic collision accidents and to utilize an ordinal regression model to identify the factors that contribute to accident severity. This will be achieved by fitting a suitable equation based on a dataset obtained from the Traffic Institute's database for the year 2021. The findings from the ordinal logistic regression analyses indicate that weather conditions, road surface, speed limit and illumination levels are significant factors that contribute to the severity of crashes with p-values of 0.003, 0.085, 0.025 and .002 respectively. Hour of the day, day of the week, week and governorate are insignificant in collision accidents in Jordan in 2021. In this comprehensive study on traffic collision accidents in Jordan during 2021, our analysis has revealed some significant findings. Our data indicates that the peak period for traffic collision accidents was between 18:00 to 18:59, and Thursday was found to have the highest number of incidents. In terms of the month, July recorded the highest number of accidents. It was also noted that Amman had the largest share of accidents. These findings highlight the need for increased awareness and stricter enforcement of traffic regulations during peak periods and in high-risk areas.

The food supply chain (FSC) is made up of producers, traders and processors who bring the product from supply to demand through logistical processes. Food supply chains require specific methodologies for their current diagnosis, evaluation and improvement. Logistics in food supply chain requires to be managed according to its nature. This article identifies the different methodologies through a systematic literature review of publications from 2005 to 2022, using Web of Science, Scopus and Google Scholar search engines, in order to establish the state of the art. As a result of this review, a new taxonomy is proposed and includes the following methodological groups: management, qualitative, quantitative, multi-criteria decision-making (MCDM), statistics, machine learning, mathematical modelling, discrete simulation, system dynamics and others. The methodologies of characterization, evaluation and improvement are classified into two main groups of logistical means and modes. The performance measures most commonly used in the methodologies by the researchers were also identified. From the article, discussions, challenges and trends are generated to identify possible future research and different gaps.

The increase in computer computing power and the development of simulation software make it possible to realise very accurate predictions of the impact of decisions on systems. The cost of investments in streamlining logistics and manufacturing systems is usually high. Therefore, verifying whether the implemented improvement will have a real intended impact on the system is necessary. The use of simulation helps reduce the risk of uncertainty in such projects. The article describes the simulation performed in the software Tecnomatix Plant Simulation 15.2 and their use in its described methodology for simulation study with achieved results. The study was carried out to streamline manual assembly in a company engaged in the production of car seats, namely car rear seats and their manipulation processes. The simulation itself was supposed to answer the question of whether it is possible to produce faster customer line tact and whether it is possible to reduce the number of workers without influencing line performance. The very design of the content and number of simulation experiments was realised in two main aspects. These aspects are whether changing the organisation of the workplace will bring the desired effect and whether the installation of new equipment can improve performance even more. The resulting solution helped reduce the investment uncertainty and estimated that the best two solutions would increase the assembly line performance by 0.94% or 6.89%, respectively.

Academic research on third-party logistics operators selecting warehouse management systems is scarce at best, based on found 86 area-specific studies written in English. Only 17 studies had mentions of 3PL and WMS but did not directly reference 3PL using WMS. Eighty-six studies covering four main categories contributed to understanding ongoing research in WMS characteristics and the 3PL context. One category is warehouse characteristics relevant to WMS, and the others concern the warehouse management system as its taxonomy, functions, features, and deployment considerations. Within these four categories, 17 subtopic areas were identified. WMS deployment considerations had the highest number of subtopics (ten), being the most focused area for WMS selection considerations for the system's successful implementation and operation usage. WMS functions and features category contained only a subtopic, indicating a need for additional research on operational functions in management systems and 3PL operations context. Award-winning 3PL validated our findings, utilizing their extensive industry experience. Based on the 3PLs validation review, fast-developing and technology areas, such as digitalization and the newest warehouse management technologies, were the only areas missing from the academic literature. Research is carried out to map the missing specific digitalization, technology-based research, development, innovation possibilities, and WMS sustainability-related knowledge gaps. By addressing the knowledge gap in existing literature, the study significantly contributes to understanding WMS utilization in the 3PL context, providing new insights into WMS characteristics overview, advancing research in 3PL logistics selecting WMS, and defining future research venues of WMS aspects.
