This paper aims to study a multi-level reinjection current source converter (MLR-CSC) that adds attracting properties such as the self-commutation and pulse multiplication to the thyristor converter, which is of great significance for increasing the device capacity and reducing current harmonics on the grid side. Particularly, designing advantageous driving methods of the reinjection circuit is a critical issue that impacts the harmonic reduction and operation reliability of the MLR-CSC.

To deal with the mentioned issue, this paper takes the five-level reinjection current source converter (FLR-CSC), which is a type of the MLR-CSC, as the research object. Then, a method that can fully use combinations of five-level reinjection switching functions based on the concept of decomposition and recombination is proposed. It is worthy to mention that the proposed method can be easily extended to other multi-level reinjection circuits. Moreover, the working principle of the three-phase bridge circuit based on semi-controlled thyristors in the FLR-CSC that can achieve the four-quadrant power conversion is analyzed in detail.

Finally, the simulation and experimental results of FLR-CSC verify the effectiveness of the proposed reinjection circuit driving method and the operating principle of four-quadrant power conversion in this paper.

The outstanding features of the proposed driving method for FLR-CSC in this paper include combinations of reinjection switching functions that are fully exploited through three simple steps and can be conveniently extended to other multi-level reinjection circuits.

With the function of reconstructing and promoting traditional industries in China, logistic service industry (LSI) still consumes a great deal of energy. The purpose of this paper is to empirically analyse the relationship between energy consumption of logistics and its influential factors in China, and through this, identify the most important factor and give a significant research of this factor afterwards.

Using a quantitative analysis of the industry composition of energy consumption and the structure of energy consumption in LSI, the serious condition of China's energy conservation of LSI was found. Correlated analysis and co‐integration analysis were adopted to identify how these factors affected the energy conservation of LSI and how to construct environmental logistics in China.

The paper found mileage traveled by train is the most important factor of energy consumption in LSI, while traveling miles of highway is the second. The former was negative correlation with the total of energy consumption while the latter was positive correlation.

Because of the deficiency of data in China, this research is based on the data of 30 years, which is not testified as long enough for this research. This would indicate that the conclusions of this paper are approximate values. A closer look should be taken at the effectiveness of some of the other factors suggested in the previous research on this topic.

The paper outlines ways to effectively construct environmental logistics in China which would promote the energy conservation and sustainable development of this country. Since the total consumption of energy in China accounts for a certain proportion of the world, this will benefit other countries as well.

This paper is one of the first of its kind to develop and empirically analyze the relationship between energy consumption of LSI and its influential factors in China. It uniquely contributes towards helping us find approaches to constructing China's environmental logistics and will have far‐reaching implications for other developing countries.

Drawing upon the framework of social exchange theory, this study investigated the influence of work-life balance, procedural justice and distributive justice on job satisfaction and turnover intention among Vietnamese millennials.

Employing a quantitative research method, the authors collected a sample of 258 millennial participants in Vietnam. Utilizing the method of multiple regression analysis, the collected data were rigorously examined.

The results showed that job satisfaction is negatively related to the turnover intention of the millennial generation in Vietnam. Distributive justice is a stronger predictor of job satisfaction than procedural justice. Of particular note, the study revealed an intriguing result: work-life balance does not have a significant influence on job satisfaction among millennials.

Leveraging insights from national cultural theories, the authors' findings provide some insightful explanations of what drives millennials in Vietnam to consider leaving their organizations.

The study provides some insights for policymakers in Vietnam and other similar developing countries to reform their approach at managing the millennial generation.

The research addresses the existing gap in literature by delving into the underlying factors driving the propensity of Vietnamese millennials to frequently switch jobs.

This study examines the impact of China's trade and foreign direct investment (FDI) on Africa's global value chain (GVC) participation and economic upgrading.

The study covered 48 African countries, cutting across the western, eastern, central, southern and northern subregions to cover the heterogeneity of the continent. The study adopted feasible generalized least squares panel VAR-Granger causality Wald test and system generalized methods of moments techniques for estimation.

Overall, China's FDI to Africa and US-Africa trade have a linear relationship with Africa's GVC involvement and economic upgrading. The findings suggest that although China-Africa trade has a positive impact on GVC engagement and upgrading, the marginal effect decreases in the face of US-Africa and EU-Africa trade.

This study provides new evidence on the impact of China's FDI and trade on African economies' GVC participation and economic upgrading. To the best of the authors’ knowledge, this is the first study to empirically explore the effects of China's FDI and trade on Africa's GVC integration and economic upgrading as well as from the perspectives of backward and forward GVC participation. Furthermore, the study empirically examines whether the effects of Africa's economic cooperation with China relative to its GVC engagement differ from those of Europe (EU) and the US via a comparative regression.

This paper aims that mobile health (mHealth) applications have emerged as a key tool to support public health. However, there are only a few studies examining the influences of health-related ascribes on continuance intention to use mHealth apps and how these influences are contingent on gender in the mHealth app using context.

This study takes the protection motivation theory as a theoretical framework to examine the ordered relationship between threat and coping appraisals and their impacts on continuance intention to use mHealth apps. In addition, this study further extends the literature on gender differences into the mHealth app's context to investigate the moderating role of gender. The suggested hypotheses are confirmed by a structural equation modeling approach and multigroup investigation employing survey data of 345 users of Spring Rain Doctor in China, a typical mHealth app.

The findings suggest that the impact of perceived disease threat on user's continuance intention is mediated entirely by coping appraisals. Furthermore, the three coping appraisals' impacts are contingent upon gender. Specifically, response efficacy is more crucial for male users in forecasting continuance intention, whereas self-efficacy and response cost have a more salient influence on continuance intention for female users.

This study examines the ordered influences of threat and coping appraisal, moderated by gender, on continuance intention on use mHealth apps. These findings could contribute to relevant theoretical and practical implications.

Gift-givers are often confronted with the possibility of choosing gifts that are inconsistent with their own attitudes (“attitude-inconsistent gifts”). For example, a gun opposer may be faced with the possibility of choosing gun paraphernalia as a gift, and a vegetarian might be forced to consider the possibility of choosing a steakhouse gift card as a gift. This study aims to compare givers’ decision-making when they are confronted with the possibility of choosing attitude-inconsistent gifts with their decision-making when they are faced with the possibility of choosing gifts that are neither inconsistent nor consistent with their attitudes (“attitude-neutral gifts”).

Seven experimental studies test the hypotheses. These studies have participants make decisions as givers and use a variety of gifts, giver-recipient relationships, gifting occasions and dependent variables, as well as both consequential and hypothetical decisions.

Givers strategically avoid choosing attitude-inconsistent (vs attitude-neutral) gifts, even when they believe that these kinds of gifts are the ones that recipients desire the most. This aversion emerges because givers anticipate that choosing an attitude-inconsistent (vs attitude-neutral) gift would cause them to experience a higher level of psychological discomfort.

This research documents a novel gift-giving phenomenon (givers’ aversion to attitude-inconsistent gifts), one of the most widespread forms of intentional preference-mismatching in gift-giving (givers’ avoidance of attitude-inconsistent gifts when they believe that these kinds of gifts are the ones that recipients desire the most), and a psychological mechanism that has a strong influence on givers’ decision-making but was yet to be explored in the gift-giving literature (givers’ anticipations of psychological discomfort). Collectively, these facets improve the field’s understanding of consumer gift-giving and call into question the assumption that gift-giving is aimed predominantly at pleasing the recipient.

This research suggests that if gift-givers want to be more financially efficient, they should refrain from contemplating the feelings of psychological discomfort that they would experience from choosing an attitude-inconsistent gift and instead focus on selecting the gift that the recipient desires the most. Moreover, it indicates that gift-givers’ tendency to avoid preferred, attitude-inconsistent gifts can have undesirable social and well-being consequences. Finally, it suggests that firms’ bottom lines may be harmed by givers’ aversion to attitude-inconsistent gifts, and that firms selling products that are likely attitude-inconsistent for segments of consumers should think carefully about advertising those products as gifts.

The gift-giving literature has recently documented multiple cases of givers intentionally refraining from choosing the gifts that they believe best match recipients’ preferences. Yet, the present work shows that there was a considerable gap in this segment of the gift-giving literature. Specifically, the present research documents a previously unexplored, but highly common, instance in which intentional preference-mismatching in gift-giving occurs: whenever a potential gift is attitude-inconsistent. Moreover, this work sheds light on a psychological mechanism that plays an important role in givers’ decision-making but was yet to be explored in the gift-giving literature: givers’ anticipated feelings of psychological discomfort.

The purpose of this paper is to assess the water quality parameters resulting on: First, the flow direction in biofilters (ascending or descending), second, constructed wetland (CW) with local plant species and third, the combined system for the removal of organic matter and nutrients pollutants from water in arid regions.

An integrated system is presented and tested in situ with a vertical up-flow and down-flow biofilters. Two configurations schemes are followed by a three separated horizontal subsurface CWs: two planted with Phragmites australis, Typha latifolia and the third unplanted. The methodology is based on a statistical analysis of the collected data.

The present experiment demonstrated that the wetlands planted with P. australis and T. latifolia showed the highest removal. Moreover, T. latifolia performed better than P. australis for most of the parameters, notably in the first system, whereas the wetland efficiency indicated that P. australis contributed greatly to the removal of TP in the first system and NO₃-N in the second system. In general, for the highest removal efficiencies of the combined biofilters and wetlands system, the present study demonstrated that the first system performed better than the second for all the parameters.

The originality of the research is that it compares in situ two biofilter systems: vertical up-flow and down-flow biofilters. To avoid the effects of domestic wastewater that is discharged directly without treatment in the Oued Righ channel or in the lake, this integrated system can be one of the alternatives for wastewater treatment, as it reveals the need to protect aquatic ecosystems in arid regions, and can decrease the risks to human health and the environment.

This article analyzes recent Japanese efforts to recruit care labor from seven Asian countries to identify the relative contributions to migrants and their respective countries' health systems. Besides considering the factors affecting migration from, and benefits to, sending countries, it asks how differences in the role of public and private actors may matter.

The study uses two stages of analysis. The first uses quantitative and qualitative data for seven countries that send care labor migrants to Japan to identify differences in benefits for individual migrants and health care systems in the sending countries. The second stage examines recent initiatives for funding care worker training in Japan to assess the relative impacts of different public-private cooperative arrangements, especially in terms of Vietnam.

In addition to general migration policy mechanisms provided by the destination country, bilateral relationships and foreign assistance, along with economic, demographic and health care conditions in the origin countries, contribute to the relative benefits of migration. Among countries supplying care labor to Japan, Vietnam is obtaining the most benefits for its health care system in return.

Responding to central concerns surrounding care labor migration, the article compares across countries sending care workers to a single country. The comparison highlights a constellation of factors that contribute the greatest benefits. The article identifies how different types of public and private relationships can influence this process. The study provides observations applicable to other welfare states developing care labor migration relationships.

The enormous amount of waste generated and the scarcity of natural resources worldwide have encouraged societies and industries to adopt the Circular Supply Chain (CSC) concept. With a focus on zero-waste generation, Circular Economy (CE) mimics the ecosystem cycle as an alternative to the traditional linear economic model. This paper aims to investigate the evolution of research themes in this research area, hence, trace the trajectory of development in the field of CSC.

The authors conduct scientometric analysis using Pajek and VOSviewer software to identify key themes in the Circular Supply Chain Management (CSCM) field. The Citation Path Analysis (CPA), including Main Path and Local Path analysis, has been followed by a critical review of the papers. This paper includes highlighting the interrelationships between the information flows in the topic of study as well as an analysis of keywords co-occurrence.

The analysis of keywords co-occurrence revealed that the earlier years of research in CSC were more inclined toward value chain, stakeholders and green supply chains, whereas, in recent years, topics like logistics, Industry 4.0 and food supply chain have been more focused upon. Further, the Main Path Analysis (MPA) revealed an evolving trajectory that examines challenges and opportunities in CSC, the economic aspects of implementing CSC, the impact on the firm's revenue growth and collaboration between multiple echelons of a supply chain and Industry 4.0.

The adoption of scientometrics analysis unveils the hidden flow of information, various themes of research and their interconnections. The development of research trajectories and progressive attention paid to certain topics is also discovered. The research findings could be used by researchers for further theoretical and research development.

This paper traces the path of development in the field of CSC and its emerging trends and provides a thorough understanding of the same. It enables research scholars to conduct an in-depth study in the CSC domain, adding to the body of literature.
