The purpose of this paper is to study conducted electromagnetic interference (EMI) of the high-low voltage DC/DC converter based on GaN high-electron-mobility transistors (HEMTs) in electric vehicle, and design EMI filters to suppress the conducted EMI.

The conducted EMI propagation model is established through simulation and analysis studying the influences of parasitic parameters, operation mode, output power and near-field capacitive coupling effects on conducted EMI of the DC/DC converter and comparing the suppression effects of EMI filters with different topologies to select the best EMI filter.

It is shown that parasitic parameters, operation mode, output power and near-field capacitive coupling effects can affect the conducted EMI of the DC/DC converter, and EMI filters of the CLC topology can effectively suppress the conducted EMI below the limit of CISPR 25.

Analysis of conducted EMI and design of EMI filters greatly facilitate further explorations and studies on EMI problems of the high-low voltage DC/DC converter based on GaN HEMTs.

The hefty fines levied on credit institutions in recent years for cases of misconduct, including poor behavioural standards, operational control deficiencies and regulatory breaches more broadly, has been defined by regulatory authorities and the financial sector more broadly as ‘conduct risk’. There is no official definition of conduct risk, as conduct risk profiles are unique to each firm and, therefore, there can never be a one-size-fits-all framework in place. Conceptually, conduct risk is a broad notion that touches every part of an enterprise framework, including culture, customer contact, corporate governance, ethics and integrity, conflicts of interest and compliance, amongst others. As a result, credit institutions tend to associate conduct risk with regulatory censure, financial detriment, poor customer outcomes, and, importantly, reputational damage. In light of the significant consequences of misconduct, recent regulatory measures have sought to specifically target these drivers. In this chapter the author discussed the regulatory spotlight on conduct risk, which continues to top the regulators’ agenda in view of its seriousness and considered the role of the board in managing conduct risk, whilst elaborating on the importance of board evaluations in this respect.

The use of structured literature review methods like bibliometric analysis is growing in the management fields, but there is limited knowledge on how they can be facilitated by technology. Hence, we conducted a broad overview of software tools, their roles, and limitations in structured (bibliometric) literature reviewing activities. Subsequently, we show that several software tools are freely available to aid in searching the literature, identifying/ extracting relevant publications, screening/assessing quality of the extracted data, and performing analyses to generate insights from the literature. However, their applications may be confronted with several challenges such as limited analytical and functional capabilities, inadequate technological skills of researchers, and the fact that the researcher's insights are still needed to generate compelling conclusions from the results produced by software tools. Consequently, we contribute toward advancing the methodologies for performing structured reviews by providing a comprehensive and updated overview of the knowledge base of key technological software tools and the conduct of structured or bibliometric literature reviews.

This study aims to examine how academic library directors conducted meetings in the change process and the factors influencing the approaches used.

Bolman and Deal's reframing change model provided the foundation for this research. An online survey was sent to 1,010 academic library directors in the USA. The response rate was 59 percent. The qualitative data were analyzed using content analysis. The collected quantitative and qualitative data were analyzed using descriptive (frequencies, percentages, means, standard deviations) and inferential statistics (binary and multinomial logistic regressions).

Most directors used multiple approaches to conduct meetings in the change process. The structural and human resource approaches were the most frequent single approaches. Regression analysis confirms that demographics, human capital, and library variables play significant roles in conducting meetings.

Data in this study were collected from directors in libraries of doctoral granting, master‐granting, and baccalaureate‐only colleges, and universities. Accordingly, the results of the study might not be generalized to college and university libraries outside this classification.

This paper provides a useful overview of the approaches used to conduct meetings in the change process and the factors influencing the approaches used.

Directors may use the results to reflect on different options of the strategies for conducting meetings in the change process and balance the weight of the factors' influences. The results may also help librarians better understand various approaches to conducting meetings in the change process.

This study aims to investigate whether firms involved in a major corruption scandal, with broad ramifications across several emerging and advanced markets, design the content of their corporate codes of conduct to either improve corporate ethical standards and practices or merely manipulate the impression of stakeholders.

This study adopts an impression management perspective. It uses content analysis techniques to examine the codes of conduct adopted by seven Brazilian engineering and construction multinationals accused of corruption. The analysis covered five major themes: (1) forms of corruption, (2) values or principles, (3) interested parties, (4) procedures and routines and (5) punitive action.

The study provides detailed evidence that the codes of conduct adopted by these firms are mere artifices that aimed at meeting legal requirements but do not target the relevant corporate audience involved in grand corruption. At best, such a code may impede petty and bureaucratic corruption.

This research contributes to improving the understanding of how Latin American multinationals adopted codes of conduct after a major scandal and how they failed—at least to some extent—to design codes complying with established corporate governance principles. It shows that management manipulated the impression of stakeholders by selectively adopting or omitting certain terms, examining or concealing various issues and addressing mainly petty crimes rather than grand corruption. It also identifies areas where Western ethical values conflict with established practices and cultural norms in Latin America.

The World Bank-sponsored public financial management reforms attempt to instil fiscal discipline through techno-managerial packages. Taking Ghana's integrated financial management information system (IFMIS) as a case, this paper explores how and why local actors engaged in counter-conduct against these reforms.

Interviews, observations and documentary analyses on the operationalisation of IFMIS constitute this paper's empirical basis. Theoretically, the paper draws on Foucauldian notions of governmentality and counter-conduct.

Empirics demonstrate how and why politicians and bureaucrats enacted ways of escaping, evading and subverting IFMIS's disciplinary regime. Politicians found the new accounting regime too constraining to their electoral and patronage politics and, therefore, enacted counter-conduct around the notion of political exigencies, creating expansionary fiscal conditions which the World Bank tried to mitigate through IFMIS. Perceiving the new regime as subverting their bureaucratic identity and influence, bureaucrats counter-conducted reforms through questioning, critiquing and rhetorical venting. Notably, the patronage politics of appropriating wealth and power underpins both these political and bureaucratic counter-conducts.

This study contributes to the critical accounting understanding of global public financial management reform failures by offering new empirical and theoretical insights as to how and why politicians and bureaucrats who are supposed to own and implement them nullify the global governmentality intentions of fiscal disciplining through subdued forms of resistance.

Supplier codes of conduct are amongst the most widely used practices in sustainable procurement programs. While there are limitations and risks involved in using supplier codes of conduct (including the risk of greenwashing, a weak link to action and the inability of supplier to comply), there is only a modest amount of research on the topic, other than content analysis. We aim to contribute to research both lessons learned, over a two-decade period, about the implementation and use of a supplier code of conduct from a case study, as well as, to suggest further research that can support the industry and enrich insight into the effective adoption of supply codes of conduct.

Thanks to the support of our co-author from Bayer we are able to share lessons learned by the global procurement team of Bayer and use these as a basis for suggesting questions for further research. The approach of this paper centres on the adoption and implementation of the supplier code of conduct in an effort to complement existing research on supplier codes of conduct that is largely focused on code of conduct content, less on the implementation of codes of conduct. The collaboration with our co-author from Bayer enables direct access to experiences and managerial perspectives. By considering the two-decade journey towards more sustainable supply chain management at Bayer, we are able to achieve a longitudinal perspective on adoption and implementation aspects.

Bayer ensures personal and community engagement in its sustainable procurement program in order to drive action and improve decision making along the value chains. The company regularly updates its code of conduct to stay aligned with its maturity and complements the code of conduct with a continuous improvement focus, supported by both generic and industry-specific consortia. The company has not yet been able to establish direct visibility into the conduct of tier 2 and up suppliers.

This paper helps close a gap in the literature and provides input into industry efforts in one of the most widely used practices in sustainable procurement. We hope that the research questions that we developed based on the first 20+ years of Bayer’s learning journey towards sustainable procurement will inspire research that can impact industry efforts towards creating a more sustainable future.

This paper explores the historical roots of environmental accountability in the Niger Delta region of Nigeria by focusing on the campaigns for social and environmental justice by writer Ken Saro-Wiwa and the indigenous Ogoni people.

The methods consist of an analysis of books, diaries, letters and poems written by Ken Saro-Wiwa as well as books, reports and audio recordings of panel discussions which capture the Ogoni struggle, Ken Saro-Wiwa’s activism and its impacts. The authors’ approach to the data is sensitised by Foucault’s notion of counter-conduct as it enables the authors to better grasp the creative agency of Saro-Wiwa and the Ogoni as they struggle and campaign for political autonomy, environmental justice and accountability.

The authors’ findings illustrate how Ken Saro-Wiwa’s books, letters, poems, diaries and articles provide early accounts of environmental injustices and the absence of accountability in the Niger Delta. They highlight how Saro-Wiwa and the Ogoni movement deploy counter-conduct to subvert existing power and accountability structures through innovative strategies, effective mobilisation and communication at local and international levels. The authors’ findings also highlight how these have led to specific forms of accountability for human rights and the environment at local and global levels. They also show how Saro-Wiwa’s activism and the Ogoni struggle have inspired a new generation of environmental activists and new ways of demanding accountability.

This paper presents, for the first time, an account of the historical roots of environmental accountability practices from an African and developing country context. Its focus on the historical roots of environmental accountability is also unique as it expands the view beyond the origins of environmental accounting to look more broadly at the origins of environmental accountability practices.

This paper aims to report a non-randomized control study undertaken to investigate prevalence and correlates of conduct disorder among male secondary education students in South-West Nigeria and to assess the impact of a problem-solving skills and attributional retraining (PSSAR) intervention with this population.

In total, 787 male students from two schools were screened for conduct disorder. All participants who met criteria for the disorder were allocated to either treatment (n = 55) or control (n = 47) groups. Outcome measures comprised the strengths and difficulties questionnaire (SDQ; teacher and student versions) and the teacher rating of students’ aggressive behaviors.

Of the sample, 13% were found to present with difficulties that met criteria for conduct disorder. The presence of these difficulties correlated with several demographic variables, including parental conflict and alcohol use. A statistically significant reduction in mean scores was observed for the treatment group in the student rating of the SDQ emotional subscale and total difficulties scores. Teacher ratings were less consistent in that conduct problems, prosocial behavior and total difficulties increased following the intervention, whereas peer problems and aggressive behavior were reported by teachers to reduce. No statistically significant change was found in the outcome measures for the control group.

In resource-constrained settings, school-based interventions are an important means through which treatment gaps in child and adolescent mental health can be addressed.

In resource-constrained settings, school-based interventions are an important means through which treatment gaps in child and adolescent mental health can be addressed. This study’s findings offer some preliminary support for the PSSAR intervention for conduct disorder in this context and indicate areas for further research.
