Abstract

The study of information is central to the science of Cybernetics. The communication and processing of information takes place, in general, by means of signals, which represent or describe (in other words symbolize) the entities to which the information relates. The present paper examines one of the foundation problems of Cybernetics: the principles of representing entities and the relations between them by systems of symbols. It treats these principles as extensions and generalizations of the fundamental concepts of measurement.

Abstract

Purpose

As the role of AI on human teams shifts from a tool to a teammate, the implementation of AI teammates into knowledge-intensive crowdsourcing (KI-C) contest teams represents a forward-thinking and feasible solution to improve team performance. Since contest teams are characterized by virtuality, temporality, competitiveness, and skill diversity, the human-AI interaction mechanism underlying conventional teams is no longer applicable. This study empirically analyzes the effects of AI teammate attributes on human team members’ willingness to adopt AI in crowdsourcing contests.

Design/methodology/approach

A questionnaire-based online experiment was designed to perform behavioral data collection. We obtained 206 valid anonymized samples from 28 provinces in China. The Ordinary Least Squares (OLS) model was used to test the proposed hypotheses.

Findings

We find that the transparency and explainability of AI teammates have mediating effects on human team members’ willingness to adopt AI through trust. Due to the different tendencies exhibited by members with regard to three types of cognitive load, nonlinear U-shaped relationships are observed among explainability, cognitive load, and willingness to adopt AI.

Originality/value

We provide design ideas for human-AI team mechanisms in KI-C scenarios, and rationally explain how the U-shaped relationship between AI explainability and cognitive load emerges.

Abstract

Purpose

This study aims to investigate customer experience (CE) and its relationship with intermediate variables to analyze the impact of digital banking (DB) on banks’ financial performance (FP) before Covid-19 and during the lockdown in Vietnam.

Design/methodology/approach

These research data are from a survey of Vietnamese customers. The survey was deployed to a sample of 238 and 218 customers of 20 Vietnamese commercial banks via email in 2018Q4 and 2020Q2, respectively. FP is measured using banks’ quarterly financial statements before Covid-19 and during the lockdown.

Findings

CE with DB had a significant and positive impact on FP via customer satisfaction before Covid-19, while the other two intermediate variables (word-of-mouth [WoM] and trust) had no considerable impact. During the lockdown, only WoM had a positive impact on FP. These findings indicate that before Covid-19, when customers could easily interact with their bank through many touchpoints, customer satisfaction with DB services created higher FP for the bank. However, during the lockdown, DB became the customer’s main touchpoint and WoM mediated the CE–FP relationship.

Originality/value

During the national lockdown from the beginning of the Covid-19 pandemic in January 2020, customers in Vietnam may have had different experiences with DB when no alternate modes of payment were available. The study uses Covid-19 as a moderator variable to offer different viewpoints and findings related to CE with DB and its impact on FP.

Abstract

Purpose

Project selection management is a matter of challenge for project-oriented organizations, particularly, if the decision-makers are confronted with limited resources. One of the main concerns is selecting an optimal subset that can successfully satisfy the requirements of the organization providing enough resources to the best subset of the project. The projects for which there are not enough resources or those requiring whole resources of the organization will collapse soon after failed to success. Therefore, the issue is in the risk of choosing a set of projects so that can make a balance in investment versus on collective benefit.

Design/methodology/approach

A model is presented for project selection and has been tested on the 37 available projects. This model could increase the efficiency of the whole subset of the project significantly in comparison to the other model and it was because of choosing a diverse subset of projects.

Findings

Provides a general framework for project selection and a diverse and balanced subset of projects to increase the efficiency of the selected subset. Also, reduces the impact of uncertainty risk on the project selection process.

Research limitations/implications

For the purposes of project selection, any project whose results are uncertain is a risky project because, if the project fails, it will reduce combined project value. For example, a pharmaceutical company’s R&D project is affected by the uncertain results of a specific compound. If the company invests in different compounds, a failure with one will be offset by a good result on another. Therefore, with selecting a diverse set of projects, this paper will have a different set of risks.

Originality/value

This paper discusses the risk of selecting or being responsible for selecting a project under uncertainty. Most of the projects in the field of project selection generally consider the risks facing the projects or existing models that do not take into account the risk.

Abstract

Purpose

The purpose of this paper is to present the factors associated with the employee barriers while implementing lean manufacturing within the small- and medium-scale enterprises (SMEs).

Design/methodology/approach

The structural equation modelling approach is employed to develop the initial model drawing a sample survey of 133 small and medium enterprises. The result of the study shows that the lack of well-trained and experienced staff, lack of knowledge about existing specialist, cultural resistance to change are acting as the employee barriers while implementing lean manufacturing in SMEs. Then, a further study has been conducted to develop the employee barrier model with these three factors and its contributing variables using specification search representing the sample of 117 small and medium enterprises using the following fit function criteria: Chi-square (C), Chi-square-df (C-df), Akaike information criteria, Browne-Cudeck criterion, Bayes information criterion, Chi-square divided by the degrees of freedom (C/df) and significance level (p).

Findings

The lack of well-trained and experienced staff, lack of knowledge about existing specialist, and cultural resistance to change with 19 associated elements were considered in the questionnaire. Specification search was carried out to build up the model on the collected data from 117 SMEs. The results of the specification search identified that these three factors with 15 key variables are significant to employee barrier while implementing lean manufacturing in SMEs.

Research limitations/implications

The limitation of the study was that the sample size of the study was relatively small for further research, large sample size more than 117 are to be expected.

Practical implications

The present study has explored an unfocused area of lean implementation in small and medium enterprises. The results obtained from the study are expected to help researchers, academics, and professionals for the further studies in the domain of lean manufacturing.

Social implications

To implement and understand the lean manufacturing system, government of the many countries around the world are helping and encouraging by providing financial assistance for training professionals and establishing professional associations. However, many industries are not successful in lean implementation. This research work provides to develop a strategy to tackle employee barriers for successful lean implementation.

Originality/value

Very little research has been carried out exploring employee barriers while implementing lean manufacturing in SMEs. This paper will provide value to academics, researchers and practitioners of lean by way of providing insight into significant employee barriers for lean implementation, especially in Indian industries.

Abstract

This paper analyzes the stability and the welfare properties of R&D cooperations in an oligopolistic market with n firms. It is shown that the sizes of stable coalitions vary significantly with the kind and the actual value of spillovers, the institutional arrangement of cooperation between the firms and the underlying stability concept. Moreover, the welfare maximizing coalition is rarely a stable equilibrium outcome, hence there is scope for political intervention. However, the informational requirements on part of the policy makers are high, and they are at risk to adopt inappropriate measures that are detrimental to social welfare.

Abstract

In this research, we analyze the impact of catastrophe events on risk-neutral densities which can be implied from European option markets. As catastrophe events we consider the destruction of the nuclear power plant at Fukushima and the downgrading of U.S. sovereign debt in 2011. In an event study, we analyze the impact on European blue chip index options traded at EUREX. We find that after a short adaption period, probability mass of especially risk-neutral density functions derived from long-term options is shifted toward the right side. Thus, very good states of the economy become more expensive indicating higher prices for deep out-of-the-money options. This signifies that there has been speculation on a recovery of the German stock market after the shocks.

Abstract

Purpose

This paper aims to introduce a new fault protection scheme for microgrid DC networks with ring buses.

Design/methodology/approach

It is well recognized that the protection scheme in a DC ring bus microgrid becomes very complicated due to the bidirectional power flow. To provide reliable protection, the differential current signal is decomposed into several basic modes using adaptive variational mode decomposition (VMD). In this method, the mode number and the penalty factor are chosen optimally by using arithmetic optimization algorithm, yielding satisfactory decomposition results than the conventional VMD. Weighted Kurtosis index is used as the measurement index to select the sensitive mode, which is used to evaluate the discrete Teager energy (DTE) that indicates the occurrence of DC faults. For localizing cable faults, the current signals from the two ends are used on a sample-to-sample basis to formulate the state space matrix, which is solved by using generalized least squares approach. The proposed protection method is validated in MATLAB/SIMULINK by considering various test cases.

Findings

DTE is used to detect pole-pole and pole-ground fault and other disturbances such as high-impedance faults and series arc faults with a reduced detection time (10 ms) compared to some existing techniques.

Originality/value

Verification of this method is performed considering various test cases in MATLAB/SIMULINK platform yielding fast detection timings and accurate fault location.

Abstract

This study samples 78 business decision‐makers whose cases were part of an alternative dispute resolution (ADR) process, i.e., the Public Construction Commission (PCC), which operates under the government in Taiwan, between 1997 and early 2000. The authors propose an interaction between two variations of trust—category‐based trust and experience‐based trust—and hypothesize that decision‐makers’ perceived identity with new versus old government ideology and past justice experiences (with the PCC) would jointly affect their decision preferences. The results partially support these hypotheses. The authors emphasize the critic role of trustworthiness of the third‐party ADR providers. We conclude with a discussion of the implications of the findings.

Abstract

Purpose

The current study aims to ascertain how green entrepreneurial orientation (GEO) affects green innovation performance (GIP) through the mediating mechanism of the knowledge creation process (KCP) and whether or not these associations can be strengthened or hampered by the moderating impacts of resources orchestration capabilities (ROC).

Design/methodology/approach

The research used data from managers at various levels in 154 manufacturing enterprises in Pakistan to evaluate the relationships among the constructs using hierarchical regression analysis and moderated mediation approach.

Findings

The study indicates that GEO substantially impacts firms' GIP. GEO and GIP's relationship is partially mediated by two KCP dimensions: knowledge integration (KI) and knowledge exchange (KE). Furthermore, ROC amplifies not only the effects of GEO on KE but also the effects of KE on GIP. The moderated mediation results demonstrate that KE has a greater mediating influence on GEO and GIP when ROC is higher.

Research limitations/implications

To better understand GEO's advantages and significance, future studies should look into the possible moderating mechanisms of environmental, organizational culture/green capability in the association between GEO, KCP and GIP.

Practical implications

The research helps expand the field of green entrepreneurship and GIP literature by providing a deeper knowledge of GEO and offering insight into how to boost GI in manufacturing firms.

Originality/value

This research helps fill in knowledge gaps in the field by delving further into the mechanisms by which GEO promotes GIP, both directly and indirectly, via the mediating role of KCP and the moderating impacts of ROC.
