Abstract

Purpose

In order to make full use of the generalized greyness of interval grey number, this paper analyzes the properties and its applications of generalized greyness.

Design/methodology/approach

Firstly, the static properties of generalized greyness in bounded background domain, infinite background domain and infinitesimal background domain are analyzed. Then, this paper gives the dynamic properties of generalized greyness in bounded background domain, infinite background domain and infinitesimal background domain and explains the dialectical principle contained in it. Finally, the generalized greyness is used to judge the effectiveness of interval grey number transformation.

Findings

The results show that the generalized greyness of interval grey number has relativity, normativity, unity, eternity and conservation. The static and dynamic properties of generalized greyness are the same in the infinite and infinitesimal background domain, while they are different in the bounded background domain. The generalized greyness can be used as an index to judge whether the grey number transformation is greyness or information preservation.

Practical implications

The research shows that the generalized greyness can be used as an index to judge the validity of the grey number transformation and also can be applied in grey evaluation, grey decision-making and grey prediction and so on.

Originality/value

The paper succeeds in realizing the mathematical principle of “white is black”, the “greyness clock-slow effect” of the value domain of interval grey number and the generalized greyness conservation principle, which provides a theoretical basis for the rational use of generalized greyness of interval grey number.

Abstract

Purpose

The purpose of this paper is to develop a small data set forecasting method to improve the effectiveness when making managerial decisions.

Design/methodology/approach

In the grey modeling process, appropriate background values are one of the key factors in determining forecasting accuracy. In this paper, grey compensation terms are developed to make more appropriate background values to further improve the forecasting accuracy of grey models.

Findings

In the experiment, three real cases were used to validate the effectiveness of the proposed method. The experimental results show that the proposed method can improve the accuracy of grey predictions. The results further indicate that background values determined by the proposed compensation terms can improve the accuracy of grey model in the three cases.

Originality/value

Previous studies determine appropriate background values within the limitation of traditional grey modeling process, while this study makes new background values without the limitation. The experimental results would encourage researchers to develop more accuracy grey models without the limitation when determining background values.

Abstract

According to status construction theory, a social attribute becomes imbued with status value through its association with valued resources. Yet, explanations for such associations have received scant attention. I propose that social identity processes may lead agents controlling resources to over-allocate to in-group members. This generates a doubly dissimilar situation in which actors are differentiated both with respect to a nominal characteristic and resources, leading the characteristic to become imbued with status value. I find support for this elaboration in a sample of newly founded organizations. I discuss the implications of this elaboration for further developments in status construction theory.

Abstract

The Northern Echo has long provided its newspaper in a digital form. It is now looking to use the Internet to widen its customer base and information remit. To this end two initiatives have been launched: it now provides background information to support and enhance the stories it publishes and it also runs an online reference service, which largely provides information on matters of local and national concern. This article describes and evaluates these initiatives and looks forward to their future.

Abstract

Purpose

China is by far the world’s largest energy consumer and importer. Reasonably forecasting the trend of China’s total energy consumption (CTEC) is of great significance. The purpose of this paper is to propose a new-structure grey system model (NSGM (1, 1)) to forecast CTEC.

Design/methodology/approach

Two matrices for computing the parameters of NSGM (1, 1) were defined and the specific calculation formula was derived. Since the NSGM (1, 1) model increases the number of its background values, which improves the smoothness effect of the background value and weakens the effects of extreme values in the raw sequence on the model’s performance; hence it has better simulation and prediction performances than traditional grey models. Finally, NSGM (1, 1) was used to forecast China’s total energy consumption during 2016-2025. The forecast showed CTEC will grow rapidly in the next ten years.

Findings

Therefore, in order to meet the target of keeping CTEC under control at 4.8 billion tons of standard coal in 2020, Chinese government needs to take necessary measures such as transforming the economic development pattern and enhancing the energy utilization efficiency.

Originality/value

A new-structure grey forecasting model, NSGM (1, 1), is proposed in this paper, which improves the smoothness and weakens the effects of extreme values and has a better structure and performance than those of other grey models. The authors successfully employ the new model to simulate and forecast CTEC. The research findings could aid Chinese government in formulating energy policies and help energy exporters make rational energy yield plans.

Abstract

The underdetermination argument establishes that scientists may use political values to guide inquiry, without providing criteria for distinguishing legitimate from illegitimate guidance. This chapter supplies such criteria. Analysis of the confused arguments against value-laden science reveals the fundamental criterion of illegitimate guidance: when value judgments operate to drive inquiry to a predetermined conclusion. A case study of feminist research on divorce reveals numerous legitimate ways that values can guide science without violating this standard.

Abstract

Purpose

This study investigates the relationship between buyer-supplier top management team (TMT) demographic misalignment (defined as differences in TMT composition based on background, age and gender) and environmental performance (EVP).

Design/methodology/approach

The empirical setting is publicly held US manufacturing firms that are present in both the Kinder, Lydenberg and Domini’s (KLD's) annual EVP ratings and Bloomberg's supply chain database. The study employs panel data regression methods on an unbalanced panel dataset of 7,493 dyad-year observations comprising 427 unique firms.

Findings

The research shows that misalignment in functional background and gender composition between TMTs have a negative outcome on both the buyer's and the suppliers' EVP. However, increasing presence of females across TMTs has a positive influence on EVP. Further, the research shows that misalignment based on age between the TMTs does not impact EVP in any significant way. On the contrary, increasing age across TMTs is a significant predictor of EVP.

Originality/value

This study builds on existing works in TMT heterogeneity and adds context to the heightening belief in the positive linkage between heterogeneity and performance through extension to a boundary spanning interfirm context.

Abstract

As described in the z-Tree (Zurich Toolbox for Readymade Economic Experiments) tutorial (Fischbacher, 2002), use of the z-Tree software for designing and administering research experiments is quite straightforward. z-Tree is likely to be a viable alternative for accounting researchers interested in administering a computerized experimental game, and it could offer some advantages over web-based administration or use of complicated spreadsheet tools. With little or no programming experience and no familiarity with z-Tree, a researcher can likely program the example experiment described herein to be functional within a day and ready to administer within a week. Thus, one appeal of z-Tree is the ease of programming and execution and possibly reduced investment of time by the researcher. This tutorial describes use of the z-Tree software to program a noninteractive accounting research experiment; as such, it should serve as a supplemental and more specific tutorial, with many illustrations, for accounting researchers considering using the z-Tree program.

The purpose of this paper is to present the adoption and application of the causal mapping method for cognitive distances measurement in the multicultural domain.

Abstract

Purpose

The purpose of this paper is to present the adoption and application of the causal mapping method for cognitive distances measurement in the multicultural domain.

Design/methodology/approach

Causal mapping was used to estimate differences in mental models between participants. The developed method was applied in a multicultural setting for the selection of teaching cases.

Findings

In the main study, 129 people participated in the test. Overall, 7,217 relationships were tested. A set of demographic variables were used to test the reliability and external validity of the method. The method proved to be reliable and easy to apply. A smaller second study is an application example of the method.

Research limitations/implications

The main study proposes a formula for distance ratio calculation. Moreover, this formula proved to be externally valid and reliable. Thus, it is of interest for further research in this domain.

Practical implications

Practitioners are provided with a tool for the analysis of intercultural differences with the example of the perception of cultural values to develop a better understanding and improve education in a multicultural setting. Study 2 proposes an example of the methodology application.

Originality/value

This is the first application of causal mapping in the field of values research performed in a multicultural education setting. The formula for comparing causal maps is improved upon, and an application for the field of multicultural university classes is provided.

Abstract

Purpose

The purpose of this paper is to provide a platform for young British Muslims in Tower Hamlets to share their perspectives on British values and identity, in light of the increased pressure schools are facing to actively promote “British values”.

Design/methodology/approach

Three focus groups were convened of 16-18 year olds, two all-male (one with five and one with six participants) and one all-female (five participants). Discussions were audio recorded with the data subjected to a form of thematic analysis that divided the raw data into three different categories: individual, group and group interaction data.

Findings

All but one of the participants defined themselves as British, largely due to a strong connection with British values. A minority felt this understanding was reflected back to them by society. However, the majority felt that, as ethnically Bengali and as Muslims, the opposite was the case. By judging the strength of an individual’s Britishness against the strength of their adherence to British values the government’s British values agenda is only serving to reinforce the isolation of those that feel excluded.

Originality/value

While the identities of young people, British people, and Muslims have been widely explored, there is little research that looks at the intersection of all three.
