This study aims to prepare an imprinted composite membrane with grafted temperature-sensitive blocks for the efficient adsorption and separation of rhenium(Re) from aqueous solutions.

PVDF resin membrane was used as the substrate, dopamine and chitosan (CS) were used to modify the membrane surface and temperature-sensitive block PDEA was grafted on the membrane surface. Then acrylic acid (AA) and N-methylol acrylamide (N-MAM) were used as the functional monomers, ethyleneglycol dimethacrylate (EGDMA) as the cross-linker and ascorbic acid-hydrogen peroxide (Vc-H₂O₂) as the initiator to obtain the temperature-sensitive ReO4⁻ imprinted composite membranes.

The effect of the preparation process on the performance of CS–Re–TIICM was investigated in detail, and the optimal preparation conditions were as follows: the molar ratios of AA–NH₄ReO₄, N-MAM and EGDMA were 0.13, 0.60 and 1.00, respectively. The optimal temperature and time of the reaction were 40 °C and 24 h. The maximum adsorption capacity of CS–Re–TIICM prepared under optimal conditions was 0.1071 mmol/g, and the separation was 3.90 when MnO4⁻ was used as the interfering ion. The quasi first-order kinetics model and Langmuir model were more suitable to describe the adsorption process.

This work focused on the sulphonation modification research of highly crosslinking non-polarity macroporous adsorption resin (MAR) LX1180; the adsorption behaviour of LX1180 and its chloromethylation- and sulphonation-modified products (LX1180-Cl and LX1180-SO₃₋); and the influence of the structure parameters matching degree of MAR and flavonoids on the adsorption feature and adsorption kinetics.

LX1180-SO₃₋ was obtained by the processes of chloromethylation first and then sulphonation. LX1180-Cl and LX1180-SO₃₋ were prepared through the principle of substitution reaction from LX1180 and LX1180-Cl, respectively. First, Monochloromethyl ether (ME), pre-treated ZnCl₂, NaCl and iron powder were added into the swollen LX1180 to obtain the chloromethylated LX1180. Thereafter, NaCl, NaOH and SAA were added into the swollen LX1180-Cl to obtain the sulphonation modification LX1180. The conditions were investigated and optimised; the structures of LX1180-Cl and LX1180-SO₃₋ were characterised by Fourier transform infrared chromatography (FTIR) and a specific surface area instrument. Finally, the adsorption kinetics and adsorption isotherm were used to evaluate the adsorption capacity of LX1180-Cl and LX1180-SO₃₋ for flavonoids, and the adsorptions and desorptions of LX1180-SO₃₋ with different sulphonation degree on different flavonoids were investigated systemically.

Results showed that LX1180-Cl and LX1180-SO₃₋ had been prepared successfully, and that after the sulphonation, the adsorption capacity tended to increase with the increase of adsorption time, and the equilibrium adsorption capacity of LX1180-SO₃₋ was also higher than that of LX1180.

The research only investigated the adsorption and desorption properties for only one kind of functional group, and other functional groups should also be studied in future work.

This contribution can provide a further base for the research of separation and purification of natural products with the aim to improve food additive removal or isolation and purification of flavonoids used for healthcare applications.

The adsorptions and desorptions of LX1180-SO₃₋ with different sulphonation degree on different flavonoids were investigated. The relationship between sulphonation degree and the adsorption and desorption capacities of flavonoids were also explored, and the results showed that with the increase of sulphonation degree, the adsorption of LX1180-SO₃₋ to rutin and cyanidin was maximum, while the desorption ratio was minimum at the same sulphonation degree; this phenomenon could be ascribed to the variation in the polarity matching degree.

The purpose of this paper is to propose a conceptual model investigating the impact of three constructs, environmental uncertainty, power asymmetry and information sharing on opportunism engagement in exchange relationships.

Data were collected from procurement or sales managers of 99 manufacturing firms in Kampala, Uganda’s capital using a cross-sectional survey. Hypotheses were tested in both the agricultural and non-agricultural manufacturing sectors using multiple regression runs in the SPSS software.

Environmental uncertainty increases opportunism in the agricultural sector whilst power asymmetry increases opportunism in the non-agricultural sector. Across both sectors, information sharing does not have a significant impact on opportunism.

This paper contributes to a deeper understanding of opportunism in a developing country context by highlighting the contextual factors within the agricultural and non-agricultural manufacturing sectors that influence opportunism engagement under conditions of environmental uncertainty, power asymmetry and information sharing. This paper presents implications for practice and policy to minimise opportunism with the goal of enhancing the participation of Ugandan manufacturing firms in global supply chains.

This study compares the role of procedural justice in motivating organizational retaliatory behaviors between two employee samples, one American and the other Taiwanese. The cross‐national generality of procedural justice effects on retaliation are examined with regard to three issues. First, this study considers the comparability of the link between procedural justice and retaliation between the two national samples. Second, it examines whether procedural justice effects on retaliation are mediated by organizational identity in both samples, as has been found in previous research based on U.S. employees (Tyler & Blader, 2000). Third, it investigates whether procedural justice is defined similarly in the two samples. Results indicate moderate cultural variation in the influence of procedural justice on retaliation and in the mediating role of organizational identity. Specifically, although procedural justice was slightly less predictive of retaliation among the Taiwanese sample, the association between justice and retaliation for these respondents was fully (as opposed to partially) mediated by organizational identity. Significant national differences also emerged in the meaning of procedural justice. Taiwanese employees demonstrated a balanced influence of relational and instrumental concerns when making overall procedural fairness perceptions, while U.S. employees defined procedural fairness primarily in terms of relational concerns.

Drawing on and extending the socially embedded model of thriving, this paper aims to investigate how and when customer participation promotes hospitality frontline employees’ engagement in extra-role service behavior.

A two-wave questionnaire survey was carried out among frontline service employees and their immediate supervisors in a four-star business hotel in Eastern China. Path analysis using Mplus 8.3 examined a multilevel moderated mediation model.

Customer participation has a positive effect on frontline employees’ experience of thriving, which in turn promotes their engagement in extra-role service behavior. Nevertheless, supervisors’ negative affect weakens the positive effect of customer participation.

Hotels could implement employee assistance programs, arrange training on emotional regulation and positive psychology and create a fun work environment to help alleviate supervisors’ experience of negative affect so as to lessen its adverse effect on frontline employees’ perception of customer participation.

First, this work is one of the few studies exploring how customer participation affects frontline employees’ well-being (in terms of thriving) and extra-role service behavior, which advances extant value co-creation literature. Second, the moderating role of supervisors’ negative affect enriches the limited understanding of when customer participation might not bring firm benefits. Third, by uncovering customer participation as an antecedent of employee thriving, this study extends thriving research that only attends to contexts located within organizations.

Because justice is inherently norm‐based, understanding people's perceptions of fairness in organizations requires considering the prevailing cultural standards in which those organizations operate. Social scien‐tists study cross‐cultural differences in justice primarily to comprehend the connection between culture and fairness, providing insight into the different meanings of justice around the world, and to assess the generalizability of culture‐bound organizational justice phenomena. The present studies focus on assessing generalizability, but fall short of doing so optimally because they suffer from several conceptual and methodo‐logical problems that are endemic in this literature. Cross‐cultural research suggests that although concerns about justice may be universal, operationalization of justice standards is highly particularistic. Finally, I address Gallon's Problem as it pertains to justice—that is, how observed connections between culture and justice perceptions may be inflated spuriously because of inevitable cultural diffusion. In closing, I note that the present research appears to be aimed more squarely at theory‐development rather than theory‐testing, which is appropriate, given the current state of the literature.

This study aims to investigate Chinese doctoral dissertations in supply chain management (SCM) by providing an overview of the evolution of this topic over the past 25 years.

This study reviews 1,945 doctoral dissertations in SCM from 39 Project 985 universities in China.

The annual number of SCM doctoral dissertations in China varied significantly over time, and the top producers are all strong players in the SCM field with long histories of research. The dissertations use multiple methods, of which mathematical, econometric modeling and simulation, and survey are the most frequently used. Most of the frequently used theories are borrowed from other disciplines. Traditional research topics are frequently investigated in Chinese doctoral dissertations in SCM, but the popular research topics differ by period.

This study has examined Chinese doctoral dissertations in SCM through a literature review. This study provides implications for research topics, methodological approaches, and theoretical lenses for future research. It also disseminates Chinese SCM knowledge to the global academic network to stimulate more SCM research.

In the digital economy, as artificial intelligence applications increase, big data analytical capability (BDAC) plays a crucial role, and intellectual capital is growing in importance. This study aims to examine the possible benefits and effects of intellectual capital, BDAC and integrations on operational performance.

This study collected data from firms in Asia, and a total of 257 senior managers completed a questionnaire. Confirmatory factor analysis and structural equation modeling (SEM) is used for statistical analysis.

Intellectual capital positively correlates with BDAC, and BDAC positively relates to internal integration but not to external integration. Furthermore, both internal integration and external integration positively correlate with operational performance. This study supports that internal integration is a significant mediator in the influence of BDAC on operational performance.

First, the authors provide empirical evidence that intelligent capital in intangible resources helps firms to build BDAC. Second, this study stresses the importance of BDAC in business, which enhances the integration of the whole supply chain and results in superior operational performance.

This is a first attempt from the perspective of intelligent capital and uses SEM to emphasize the relationships among BDAC, supply chain integration and performance based on unique and irreplaceable intangible resources, thus providing a new perspective on the contributing factors of BDAC.
