Abstract
A fuzzy symmetric threshold (ST) function is defined to be a fuzzy set over the set of functions. All ST functions have full memberships in this fuzzy set. For n variables, there are (2n+2) ST functions. A distance measure between a nonsymmetric threshold function and the set of all ST functions is defined and investigated. An explicit expression for the membership function of a fuzzy ST function is defined through the use of this distance measure. An algorithm for obtaining this distance measure is presented with illustrative examples. It is also shown that any function and its complement always have the same grade of membership in the class of fuzzy ST functions. Applications to concise function representation and simple function implementation are also presented with examples. In addition, most inseparable unsymmetric functions are defined and investigated. Fuzzy ST functions are relevant to the development of practical applications of fuzzy methods and might contribute to the state of the art in the implementations of fuzzy methods in the areas requiring utilization of ST functions.

Abstract
Purpose
Sales organizations embrace technological innovation. However, salespeople’s willingness to use new technology influences a firm’s return on investment, representing a significant concern for the organization. These concerns highlight tensions regarding the tradeoffs associated with technology implementations. The purpose of this study is to offer insights that help reduce the complexities of sales technology (ST) by exploring the changing dynamics of contemporary business relationships.
Design/methodology/approach
This paper synthesizes the ST literature using the service ecosystem perspective to propose the sales techno-ecosystem (STE) framework, providing new insights into organizational decision-making related to the ongoing digital transformation of sales tasks.
Findings
This synthesis of the ST literature with the service ecosystem seeks to clarify the impact of technology within the evolving nature of buyer–seller relationships by providing four unique perspectives.
Research limitations/implications
Perspective 1 reviews the sales-service ecosystem framework and develops the theoretical underpinnings and relevant terminologies. Perspective 2 summarizes critical aspects of the ST literature and provides foundations for future research in the STE. Perspective 3 offers a more granular view, explicating roles and contexts prevalent in buyer–seller–technology interactions. Perspective 4 provides a set of tenets and advances research questions related to each tenet.
Practical implications
The culmination of these four perspectives is the introduction of five key tenants designed to help guide strategy and research.
Originality/value
The paper advances Hartmann et al. (2018) service ecosystem paradigm by explicating critical aspects of its ST domain to generate insights for theory and practice.

Abstract
Purpose
Mitigating the energy trilemma (ET) is of great importance for dealing with climate change and realizing carbon neutrality. To this end, effectively assessing the level of the ET is essential. The purpose of this study is to evaluate the current situation and the spatio-temporal changes of the ET in the whole of China.
Design/methodology/approach
Moreover, based on provincial-level data in China for the period 2002–2017, and by using the dynamic estimation model, we aim to determine the specific marginal impacts of smart transportation (ST) on the ET, and the possible channels through which ST works on the ET.
Findings
We thus present the following findings: (1) The performance of both ET and its three pillars is gradually improving in China. Moreover, the situation tends to vary dramatically among various regions and provinces, and the gap between the best performers and the worst is large. (2) ST plays a significant role in inhibiting the ET, a finding that remains robust after a series of tests. And (3) the ET eradication effect of ST is caused mainly by improved innovation, advanced technical efficiency, and the increasing energy scale.
Originality/value
Accordingly, we put forward some policy recommendations to help tackle ET and accelerate ST in China.

Abstract
Purpose
The purpose of this paper is twofold: first, to advance a set of recommendations concerned with enhancing residential strata title (ST) communities’ preparation for property management in a world of climate change (CC) and second, to examine the Australian ST community’s perceptions of the recommendations advanced.
Design/methodology/approach
The study comprised three empirical phases: three meetings with an 11 person industry reference group, conduct of 18 exploratory interviews and also an on-line questionnaire survey. The survey was designed to gauge the relative merit of sixteen recommendations developed during the study’s exploratory interview phase. The survey was completed by 450 individuals representing a broad cross-section of ST stakeholders.
Findings
The study’s findings are extensive. Amongst them it is notable that the survey respondents ranked procedures taken prior and during a ST building’s construction as more important CC management opportunities than steps and procedures implemented post-building construction.
Research limitations/implications
While considerable care was taken to approach the analysis of interview data in an objective manner, it should be acknowledged that, like any research based on qualitative data, a researcher’s background is bound to introduce some biases in the way that themes in the collected data are determined and interpreted.
Practical implications
The range of practical implications arising from the study are very evident from the range of issues addressed in the 16 recommendations advanced by the study. These implications range widely from internal management suggestions such as identifying a CC champion in ST complexes, to insurance issues such as creating a low insurance or “uninsurable” ST building category.
Social implications
The survey findings reveal the extent to which expressed opinions concerning how best to adapt ST buildings and communities for CC are affected by the stakeholder group that is expressing the opinion. This highlights the likelihood that any new ST policy making relating to CC is likely to become highly politicised due to conflicting lobbying interests represented by these distinct ST stakeholders.
Originality/value
The study is believed to embody an exceedingly high level of originality. It is the first to: provide an examination of the vulnerability of ST complexes to CC, and advance recommendations concerned with changes that should be made to the building and management of ST complexes in order to address the CC challenge.

Abstract
Purpose
In the postmodern consumer society, factors such as sustainability, responsible behaviour and digital environment have direct consequences on rethinking sustainable tourism promotion through 2.0 communication policy embedded within a specific cultural context. The aim of this research is to analyse and discuss the application of 2.0 systems thinking (ST) in three countries (France, UK and Serbia) to promote sustainable tourism thinking.
Design/methodology/approach
Online tourism ads available on YouTube, Vimeo, and Dailymotion, related to the cultural contexts of the UK, France and Serbia, have been analysed through a qualitative approach based on the use of visual methods. Furthermore, sustainable tourism dimensions and discourses have been identified in each context by applying intra- and intertextual analysis.
Findings
The results show that the use of 2.0 ST to promote sustainable tourism should take into account environmental and socio-cultural issues in each cultural context. These findings show that both the UK and France promote sustainable tourism logic through applying a 2.0 ST. This is not the case with Serbia where online sustainable tourism videos are underrepresented and the online content is different from the one in the UK and France.
Research limitations/implications
This research might help tourism researchers and professionals to understand cultural differences when promoting sustainable tourism through a 2.0 communication and online videos. The results show that tourism system has to be considered as a complex and a dynamic framework where intense interlinking of social media with political, cultural, promotional, and organizational aspects of tourism systems in different countries is present.
Practical implications
The proposed framework in this study represents a tool that will enable tourism professionals to improve their sustainable tourism communication, especially the environmental and socio-cultural dimensions when considering a 2.0 communication approach.
Originality/value
The original aspect of this research is related to the analysis of interactive videos in tourism studies and to the introduction of a new framework based on 2.0 ST, used to promote sustainable tourism in a cross-cultural context.

– The purpose of this paper is to investigate the degree of corporate financial distress (DOFD) and relationship between ownership structure and the DOFD in China.
Abstract
Purpose
The purpose of this paper is to investigate the degree of corporate financial distress (DOFD) and relationship between ownership structure and the DOFD in China.
Design/methodology/approach
The authors estimate the DOFD across a sample of 378 Chinese-listed companies that got into financial distress between 2000 and 2008. The DOFD reflects long-term solvency capability, short-term liquidity capability, development capability, risk level, profitability capability, operating capacity, and cash flow capability. The authors analyze the relationship between ownership structure and the DOFD in these companies, using the panel data analysis method.
Findings
The authors find that a concentrated ownership structure is negatively related to the DOFD. Further, the results indicate that a state-owned status helps firms in decreasing their DOFD and that the separation of cash-flow rights and control rights is positively related to the DOFD. The authors also found that the Chinese special treatment (ST) system needs further improvement. The reason is that ST firms can be classified into “value” ST firms and “garbage” ST firms. They have different DOFD and change trend, so they should not be treated equally.
Originality/value
This paper find that Chinese ST system and previous research are not helpful for risk-seeking investor to distinguish and evaluate “value” ST firms and “garbage” ST firms. It is unfair to warn and punish this two kinds of firms equally, so ST system should be improved. The authors also suggest that risk-seeking investor can choose ST firms that have a concentrated ownership structure and are controlled by the state or local government. These findings are not observed in previous studies.

Abstract
Investigates urban bias in state policy making in Mexico. Refers to literature claiming that rural poverty in developing nations is a major problem because capitalism reflects an urban bias. Examines social security coverage for the rural poor in Mexico and notes that there are great variations depending on area, suggesting that social security coverage is politically negotiable. Outlines briefly the historical development of Mexico’s welfare state and uses a power resource model to demonstrate how groups with competing interests go about securing benefits from the state. Cites literature on dependency theory, indicating that rural groups have failed to mobilize politically and have therefore not secured the same state resources (such as social security benefits and housing) as urban groups, yet argues that this does not always apply in Mexico, partially due to party politics and bureaucratic paternalism. Explains how data was collected to examine regional variations in social security coverage among the rural poor and how the data was analysed. Reveal that workers in important international export markets (such as cotton and sugar) have greater political leverage in obtaining better social security benefits. Notes also that areas supporting the political party in power obtain better benefits. Concludes, therefore, that rural workers are not powerless in the face of urban capitalism and that urban bias and dependency theories do not reflect the situation in Mexico – rather social security benefits are politically negotiable.

Abstract
Purpose
Stakeholder theory (ST) argues that providing value to external stakeholders is the best way to ensure long-term business health. However, when the theory was formed, information technology (IT) played a small role in organizational operations and strategy. Although IT research recognizes stakeholders, the theoretical underpinnings of ST are rarely recognized within this context. The purpose of this paper is to remedy this issue by reviewing ST through the lens of technology adoption and training and presenting propositions for business alignment and organizational success.
Design/methodology/approach
This paper conducted a comprehensive literature review to examine all extant research at the intersection of ST, IT and information systems (IS). A total of 25 papers were retained, published between 1993 and 2016, using multiple sources for search.
Findings
Too little IT research has recognized the theoretical foundations of ST. These theoretical foundations have the potential to expand the focus of research and practice to recognize the wider impacts of technological developments. A total of six propositions are presented to highlight the need for a greater focus on external stakeholders throughout all stages of IS design, development and implementation to improve the performance of IT-related projects and IT-business units.
Originality/value
The paper addresses the research gap by integrating ST with IT and IS, providing theory-based recommendations to improve their functions within organizations. A review of all extant research at the intersection of these topics is provided.

Abstract
Purpose
The purpose of this paper is to investigate the influence of intellectual capital (IC) on the performance of Malaysian automotive manufacturing firms. It also examines the role of strategic thinking (ST) as a moderating variable in the relationship between IC and performance in these firms.
Design/methodology/approach
This study used a quantitative approach, with an initial sample of 228 firms in Malaysia. Partial least squares structural equation modelling (PLS-SEM) was employed to test the study hypotheses.
Findings
The results of the PLS-SEM analysis are as follows: Human capital (HC) and relational capital (RC) have significant effect on performance, but not structural capital (SC). ST has no moderating effect on the relationship between RC or SC and performance although it does moderate the relationship between performance and HC.
Research limitations/implications
Together with the government, CEOs hold responsibility for ensuring that organizations practice effective ST and IC. With the assistance of government, CEOs should exert every effort to be leaders in this matter. In addition, CEOs of automotive manufacturing firm should reduce their emphasis on classical ways of managing organizations processes.
Practical implications
The findings offer guidance to automotive firms considering how to develop IC and ST to improve performance, especially in Malaysia and Southeast Asia.
Originality/value
This is the first study to examine the moderating effect of ST on the relationship between IC and performance worldwide.

Abstract
This study investigates the impact of the enhanced continuous disclosure regime introduced in December 2002 on several measures of information risk in NZX‐listed stocks. We employ two microstructure models and an intraday data set to measure information risk in a sample of 71 stocks. Our empirical results show that the reforms enacted in December 2002 had no significant effect on either the level of information‐based trading or the adverse selection component of market spreads in our sample of NZX‐listed stocks.
