Abstract

Purpose

This study aims to analyze the literature on knowledge management on intellectual capital, social capital and its contribution to Iranian companies’ innovation.

Design/methodology/approach

To investigate knowledge management’s relationship on intellectual capital, social capital and innovation, using structural equation modeling based on data collected from 205 chief executive officers, production managers and marketing managers of Iranian companies. The research instrument is a standard questionnaire consisting of 109 questions in which 5 of them are demographic questions, 26 questions were asked to reveal the knowledge management process, 40 questions for intellectual capital, 21 for social capital and 17 for innovation.

Findings

The results show that knowledge management has a positive and significant relationship between intellectual capital and social capital. Knowledge management did not have a significant effect on innovation. However, intellectual capital and social capital have a significant effect on innovation. On the other hand, knowledge management mediated by intellectual capital and social capital has a positive and significant indirect effect on innovation.

Originality/value

The paper includes the implications for developing knowledge management and intellectual, social capital leading to innovation in manufacturing companies. Knowledge management can improve the innovation performance of a company if it is shared and applied effectively. This study addresses an important subject and the findings may be used by professionals and managers or another person interested in advancing knowledge management that leads to innovation.

Abstract

Purpose

Science and technology diplomacy (STD) is an emerging area in the field of public policy and technology management. The purpose of this study is to overview the concept of STD based on the two approaches “Science and Technology” and “Diplomacy” to explain its necessity for Non-Aligned Movement member countries.

Design/methodology/approach

To design the work, principal domains and sub-domains of STD are identified based on the thematic analysis. By using MAXQDA software, the initial codes are analyzed and validated for the case study. Then, six areas and 29 sub-areas are identified based on the fuzzy Delphi and the framework is designed.

Findings

STD is defined from six scopes, including political, economics, law and legal issues, social sciences, philosophy and science and technology. Each scope has its own mechanism that is discussed in the article.

Originality/value

This work is one of the first in the literature of science and technology policy making.

Abstract

Purpose

The paper seeks to provide an adaptive fuzzy logic controller for permanent magnet synchronous motor (PMSM) under direct torque control (DTC) algorithm to minimize the torque ripple.

Design/methodology/approach

The design methodology is based on vector control analysis. MATLAB simulations supported with experimental study under C++ are used to execute the proposed work.

Findings

The results show that considerable torque ripple reduction as well as considerable current ripple reduction can be achieved by utilizing adaptive fuzzy switching algorithm to fire the inverter supplying the PMSM.

Research limitations/implications

This research is limited to PMSM, however the research can be extended to include other AC motors as well. In addition, the following points can be studied, the effects of harmonics in control signals on the torque ripple. Digital and active filters as solution to these harmonics can be also addressed. The actual mathematical relation between the torque ripple and flux ripple can be studied to set the flux and torque bands width in reasonable value.

Practical implications

Based on existence DTC control system, it is only required to change the software‐switching algorithm, to provide smooth torque, given that the switching frequency of the inverter module is more than or equal to 15 kHz and the system is supplied with timers. In addition, a relatively higher DC voltage may be required to achieve higher speed compared with the traditional DTC.

Originality/value

In this paper, the stator flux position, and errors due to deviations from reference values of the torque and stator flux are used to select two active vectors while at the same time the absolute value of the torque error and the stator flux position are fuzzified to adapt the switching of the inverter in order to control the applied average voltage level in such a way as to minimize the torque ripple, so instead of fixed time table structure, a fuzzy logic is used to calculate the switching time for the selected vectors and no PI controller is used as the case in the traditional‐space vector modulation. This work is directed to motor drive system designers who seek highly smooth torque performance with fast response.

Abstract

Purpose

The purpose of this paper is to examine the various anti-corruption strategies used to fight economic and financial crimes in both the public and private sectors in Iran.

Design/methodology/approach

This paper relied essentially on a secondary source of information. Materials used were collected in an eclectic manner from published outlets such as journal publications, books, online sources and newspaper reports. Also, official documents and statutes were also used. This study’s scope is limited to issues and analysis relating to measures adopted to combat corruption in Iran.

Findings

The legal and institutional frameworks analysed indicated that Iran has a robust anti-corruption scheme. However, there is no adequate measure available to gauge the effectiveness of these measures.

Practical implications

The paper concludes that conventional anti-corruption methods are not enough to fight corruption in this present time, thus, the implementation of whistle-blower policy and allowing freedom of operation of the civil society organisations and media would assist in the fight against corruption in Iran.

Originality/value

The paper provides the legal and institutional anti-corruption frameworks in Iran. It explores the three major approaches or methods of combating corruption and other corrupt practices in Iran.

Abstract

Purpose

The purpose of this study is to provide a comprehensive conceptual internal whistleblowing model for accounting students and then test it empirically. To this end, by considering the mediating role of professional commitment (PC) and the moderating effect of the perceived moral intensity (PMI), the anticipatory socialization's impact on whistleblowing intentions has been investigated.

Design/methodology/approach

An ex-post quantitative research design has been adopted for this survey study. The statistical population of the study consisted of Iranian undergraduate accounting students close to graduation in 2020. The study utilized a self-administered survey of 211 accounting students from 8 public universities; besides, to examine the proposed hypotheses, it utilized the partial least squares structural equation modeling analysis.

Findings

The results of testing the hypotheses indicate that the constructs of anticipatory socialization (AS), PC and PMI have positive effects on whistleblowing intentions; besides, PC in the relationship between AS and whistleblowing intentions plays a complementary partial mediating role. In addition, PMI moderates the effect of PC on whistleblowing intentions, as well as the mediated effect of AS on whistleblowing intentions via PC.

Social implications

The results of this study indicate the importance of considering trait syntheses of ethics education for undergraduate students, and the need to address and familiarize students with ethical principles, goals and missions of the accounting profession in society.

Originality/value

This study, by providing a moderated mediation conceptual model, examines the important functions that AS, PC and PMI might have created in the whistleblowing process, and also provides some empirical evidence in this area; As a result, it leads to the expansion of theoretical and empirical knowledge in this field.

Abstract

Purpose

The dual epidemic of non-communicable diseases (NCDs) and human immuno-deficiency virus (HIV) in Sub-Saharan Africa has increased substantially in recent years, with cardiovascular disease representing a significant contributor to the regional burden of disease. Very little is known about the cardiovascular health of people deprived of their liberty in the region. The purpose of this study was to collate extant literature on the topic.

Design/methodology/approach

A scoping review mapped and described what is known about cardiovascular disease in prison populations in Sub-Saharan Africa. A systematic search of empirical literature with no date limitation was conducted in English. Sixteen studies representing six Sub-Saharan African countries (Cameroon, Nigeria, Guinea, Burkina Faso, Ghana and Ethiopia) were charted, categorised and thematically analysed.

Findings

Seven key themes were identified: custodial deaths and autopsy; cardiorespiratory fitness and exercise; cardiovascular disease and elderly people in prison; cardiovascular disease and women in prison; dietary deficiencies; influence of sleep patterns on cardiovascular disease; and other associated risk factors. Most natural deaths at autopsy of custodial deaths were due to cardiovascular disease. Cardiorespiratory fitness was low in prisons, and poor sleep patterns and dietary deficiencies are likely contributors to the burden of cardiovascular disease in prisons. The needs of elderly and female prison populations are ill-considered.

Originality/value

To the best of the authors’ knowledge, this is the first known attempt to scope extant literature on cardiovascular disease in Sub-Saharan African prisons. A strategic focus on the cardiovascular health of people in prison is warranted. Routine monitoring and expansion of existing prison health-care services and integration of NCD services with infectious disease (HIV and tuberculosis) programmes in prisons are required.

Abstract

Purpose

The purpose of this study is to propose an extended reliability method for an industrial motor drive by integrating the physics of failure (PoF).

Design/methodology/approach

Industrial motor drive systems (IMDS) are currently expected to perform beyond the desired operating conditions to meet the demand. The PoF of the subsystem affects its reliability under such harsh operating circumstances. It is crucial to estimate reliability by integrating PoF, which helps in understanding its impact and to develop a fault-tolerant design, particularly in such an integrated drive system. An integrated PoF extended reliability method for industrial drive system is proposed to address this issue. In research, the numerical failure rate of each component of industrial drive is obtained first with the help of the MIL-HDBK-217 military handbook. Furthermore, the mathematically deduced proposed approach is modeled in the GoldSim Monte Carlo reliability workbench.

Findings

From the results, for a 15% rise in integrated PoF, the reliability and availability of the entire IMDS dropped by 23%, resulting in an impact on mean time to failure (MTTF).

Originality/value

The integrated PoF of the motor and motor controller affects industrial drive reliability, which falls to 0.18 with the least MTTF (2.27 years); whose overall reliability of industrial drive drops to 0.06 if it is additionally integrated with communication protocol.
