The purpose of this paper is to develop a multi-criterion group decision-making (MCGDM) method by combining the regret theory and the Choquet integral under 2-tuple linguistic environment and apply the proposed method to deal with the supplier selection problem.

When making a decision, the decision-maker is more willing to choose the alternative(s) which is preferred by the experts so as to avoid the regret. At the same time, the correlative relationships among the criterion set can be sufficiently described by the fuzzy measures, later the evaluations of a group of criteria can be aggregated by means of the Choquet integral. Hence, the authors cope with the MCGDM problems by combining the regret theory and the Choquet integral, where the fuzzy measures of criteria are partly known or completely unknown and the evaluations are expressed by 2-tuples. The vertical and the horizontal regret-rejoice functions are defined at first. Then, a model aiming to determine the missing fuzzy measures is constructed. Based on which, an MCGDM method is proposed. The proposed method is applied to tackle a practical decision-making problem to verify its feasibility and the effectiveness.

The vertical and the horizontal regret-rejoice functions are defined. The relationships of the fuzzy measures are expressed by the sets. A model is built for determining the fuzzy measures. Based on which, an MCGDM method is proposed. The results show that the proposed method can solve the MCGDM problems within the context of 2-tuple, where the decision-maker avoids the regret and the criteria are correlative.

The paper proposes an MCGDM method by combining the regret theory and the Choquet integral, which is suitable for dealing with a variety of decision-making problems.

The purpose of this paper is to propose a consensus method for multi-attribute group decision-making (MAGDM) problems based on preference-approval structure and regret theory, which can improve the efficiency of decision-making and promote the consensus level among individuals.

First, a new method to obtain the reference points based on regret theory and expert weighting method is proposed. Second, a consensus reaching method based on preference-approval structure is proposed. Then, an adjustment mechanism to further improve the consensus level between individuals is designed. Finally, an example of the assessment of elderly care institutions is used to illustrate the feasibility and effectiveness of the proposed method.

The feasibility and validity of the proposed method are verified by comparing with the advanced two-stage minimum adjustment method. The compared results show that the proposed method is more consistent with the actual situation.

This paper presents a consensus reaching method for MAGDM based on preference-approval structure, which considers the avoidance behaviors of individuals and reference points. Decision makers (DMs) can use this approach to rank and categorize alternatives while further increasing the level of consensus among them. This can further help determine the optimal alternative more efficiently.

A new MAGDM problem based on the combination of regret theory and individual reference points is proposed. Besides, a new method of obtaining experts' weights and a consensus reaching method for MAGDM based on preference-approval structure are designed.

Power structure research examines core issues in the discipline of sociology; yet this important area of study is declining because of the conceptual, theoretical, and methodological problems. In this paper, I address each of these problems and proposing solutions. I then test the validity of my proposed solutions by conducting empirical analyses examining how big business and labor political action committee (PAC) contributors influence U.S. House decision making. My findings vividly show significant big business influence on House decision making, but negligible labor influence. These findings carry considerable implications for power structure theorizing and research, and provide a solid foundation for future power structure work.

Institutional theory assumes practice adoption and subsequent decoupling. However, there is a range of alternative organizational theories that challenge this view and offer instead their reinterpretation, extension and modification of institutional predictions with regard to the adoption and possible range of various responses and processes that follow the decision to adopt. This paper aims to review this spectrum of theories and suggest how they clarify, supplement, correct, restrict and/or abandon some institutional explanations and predictions.

Extensions and alternatives to institutional theory are mainly motivated by the need to have a theory of practice adoption and variation, and a plethora of alternative practice adoption theories currently exists in the literature. The authors review these theories and compare them against institutional theory and against each other.

The analysis revealed shortcomings and advantages of alternative theories compared to institutional theory and against each other. It is suggested which theory is most useful in each domain of application. The authors review and compare institutional theory, Scandinavian institutionalism, management fashion theory, virus theory and institutional inertia theory and analyze how and whether they are able to reproduce the success of institutional theory and successfully address and resolve its shortcomings and gaps. The authors conclude by discussing whether regular emergences of new theories that account for the idea-handling stage of diffusion signals institutional theory’s limit of validity in this domain.

The problem of idea emergence/diffusion/disappearance and adoption/variation/use are fundamentally different, but both of them motivated researchers to go beyond institutional theory. Despite being the dominant theory of organizations internally consistent and explaining a wide range of empirical observations, it is evident that institutional theory is not a complete theory. This paper contributes to this problem by exploring and comparing existing candidates for practice variation theory.

The main purpose of this paper is first to discern the overwhelming influence of Kantian thought in the development of mainstream political economic doctrines. In this we will show that the Kantian philosophical influence has introduced an abiding element of duality in all matters of the western liberal theory of social contract and political economy. The nature of Kantian moral philosophy will be shown to have left the study of political economy by and large ethically neutral by treating the role of morals, ethics and values exogenously to the economic system. We will then introduce some substantive elements of an alternative approach to the treatment of ethics and values in the socio‐economic system. We will show that in the alternative approach to the study of social contract theory and political economy the ethical considerations appear as endogenous elements and strongly negate the Kantian principle of duality and individualistic rationalism.

This study is centered on the identification of the most appropriate Technology Adoption (TA) model for investigating the adoption of Industry 4.0 technologies within pharmaceutical and related enterprises. The aim is to facilitate a smooth transition to advanced technologies while concurrently achieving environmental sustainability.

Selection of a suitable TA theory is carried out using a hybrid multi-criteria decision-making (MCDM) approach incorporating PIvot Pairwise RElative Criteria Importance Assessment (PIPRECIA) and Fuzzy Measurement of alternatives and ranking according to Compromise solution (F-MARCOS) methods. A group of three experts is formulated for the ranking of criteria and alternatives based on those criteria.

The results indicate that out of all six TA models considered unified theory of acceptance and use of technology (UTAUT) model gets the highest utility function value, followed by the technical adoption model (TAM). Further, sensitivity analysis is conducted to confirm the validity of the MCDM model employed.

Challenging times like COVID-19 pointed out the importance of technology in the pharmaceutical and healthcare sectors. TA studies in this area can help in the identification of critical factors that can assist pharmaceutical firms in their efforts to embrace emerging technologies, enhance their outputs and increase their efficiency.

The novelty of this research lies in the fact that the utilization of a TA theory prior to its implementation has not been witnessed in existing scholarly literature. The utilization of a TA theory, specifically within the pharmaceutical industry, can assist enterprises in directing their attention toward pertinent factors when contemplating the implementation of emerging technologies and achieving sustainable development.

This paper responds to ongoing calls to develop alternative management theory to guide management practice. In particular, the purpose of the paper is to demonstrate the merit of developing sustainable management theory and organizational practices that parallel conventional management theory and practices. Sustainable theory is based on a variation of virtue theory that seeks to achieve multiple forms of well-being for multiple stakeholders in the immediate as well as distant future. To illustrate the approach, the authors develop a sustainable variation of goal setting theory.

The paper includes three parts. First, the authors establish the need for developing sustainable management theory (based on virtue theory) that parallels conventional management theory. Second, the authors identify and briefly review the main tenets of goal setting theory and then describe a Sustainable variation of this theory. Finally, the authors discuss the implications of the paper for management and organization theory and practice.

The conceptual arguments for a sustainable version of goal setting theory based in virtue are supported by research and practitioner examples.

Although there is growing concern regarding the shortcomings of management theory and practice based on a materialist-individualist moral-point-of-view, few alternatives have been discussed in detail. This paper presents an alternative based in virtue theory and illustrates how it relates to goal setting theory and practice.

Current economic conditions have identified a complication if not conflict in the application of valuation analysis assumptions with the free fall in asset prices observed since 2007. Discrepancies in debt obligations (from prior periods) with underlying collateral value have been opined to be an unforeseen anomaly. This investigation aims to observe an alternative perspective using data from 1900 to the present.

This 110‐year period of observation shows that return (value) volatility is the characteristic norm of the market system. Showing volatility as a fundamental characteristic of economic and property performance supports conjecture by definition, observation and rationality that valuation analysis had to be successfully employed in prior down cycles and across divergent economic regimes. A systematic literature search was conducted to identify the application of specific value theory, premises and concepts with appropriate valuation techniques in given economic regimes. The variables derived from the literature and practices observed and designated as operating across time emphasizing recorded recessions are then tested for statistically significant associations using χ² tests.

The findings show that traditional value techniques are successfully applied in stabilized and even accelerated growth periods, but weaken and even break down during down markets. Alternative approaches and techniques are emphasized and developed during these periods that address specific problems but are befitting more general issues. The alternative perspectives are then observed to operate, generating much debate for extended periods. They are then incorporated as orthodox or disappear as issues. This study identifies a statistical link between the economic and valuation concerns of the Great Depression of the 1930s and the current Great Recession of 2007‐2009. The more relevant finding, however, is that the period following the depression of the 1930s, which shows a period characterized as using innovation and alternative valuation techniques, was continued into a period that ran from the 1950s into the mid‐1990s. This was a period of stabilization, at least into the early 1980s. The deregulation of the 1980s generated a period of fewer cycles but major magnitude shifts in the less frequent measures of volatility. Unfortunately, the sophistication in debate concerning valuation procedure and valuation premises, as statistically measured, declined from the 1990s into the present period. The present economy reflects statistical measures similar to those observed from 1900‐1930.

Given the 110 years considered in the study, the findings should not be considered original with regard to assisting the general welfare or professional decision making. However, given that the market shifted from being a useful institution to assist in the allocation and distribution of property to being a religious caveat that could only result in perfect solutions to solve all social needs, wants and ills, the findings emphasizing valuation techniques based on rational value premises that can operate to assist inference of future events subject to divergent and cyclical operations might be calmed to offer very useful assistance with procedure based on fundamentals and expression of behaviour that has long been vilified. The uses of the patterns identified in this study need to be incorporated into causal analysis.

Decision-making problems in emergency plan selection for epidemic prevention and control (EPAC) are generally characterized by risky and uncertainty due to multiple possible emergency states and vagueness of decision information. In the process of emergency plan selection for EPAC, it is necessary to consider several obvious features, i.e. different states of epidemics, dynamic evolvement process of epidemics and decision-makers' (DMs') psychological factors such as risk preference and loss aversion.

In this paper, a novel decision-making method based on cumulative prospect theory (CPT) is proposed to solve emergency plan selection of an epidemic problem, which is generally regarded as hybrid-information multi-attribute decision-making (HI-MADM) problems in major epidemics. Initially, considering the psychological factors of DMs, the expectations of DMs are chosen as reference points to normalize the expectation vectors and decision information with three different formats. Subsequently, the matrix of gains and losses is established according to the reference points. Furthermore, the prospect value of each alternative is obtained and the comprehensive prospect values of alternatives under different states are calculated. Accordingly, the ranking of alternatives can be obtained.

The validity and robustness of the proposed method are demonstrated by a case calculation of emergency plan selection. Meanwhile, sensitivity analysis and comparison analysis with fuzzy similarity to ideal solution (FTOPSIS) method and TODIM (an acronym in Portuguese for interactive and MADM) method illustrate the effectiveness and superiority of the proposed method.

An emergency plan selection method is proposed for EPAC based on CPT, taking into account the psychological factors of DMs.
