Integrated reporting and changes in management control systems in large Japanese companies
Authors: Hosoda Masahiro
Published: December 2020

Purpose

This study aims to examine the integration of integrated reporting (IR) into the formal control systems (FCSs) early adopters use to implement IR, and investigate whether it drives informal control systems (ICSs) change at this early stage.

Design/methodology/approach

A case study was conducted in seven large Japanese companies. Data were gathered through semi-structured interviews and e-mail exchanges with the managers responsible for developing integrated reports in Japanese companies that excel in IR practices. Content analysis was adopted to analyze the data.

Findings

The results showed incremental changes to the integration of IR into FCSs. However, the integration may not cause radical changes to ICSs because all sample companies recognized the importance and necessity of embedding integrated thinking in all levels of companies to put it into practice for value creation over time.

Originality/value

This study contributes to IR research from an internal corporate perspective. Specifically, this study provides new knowledge on the relationships between IR and MCSs. This research also gives new insight into operationalization and internalization of sustainability in terms of IR and MCSs in companies, not only in Japan, but also worldwide.
Integrating management control systems, mindfulness and sustainability: an occupational health and safety perspective
Authors: Shahbaz Wahab , Sajjad Aymen
Published: December 2020

Purpose

The purpose of this paper is to integrate the notions of management control systems (MCS), mindfulness and sustainability, and introduce a framework demonstrating how sustainability outcomes – specifically occupational health and safety (OHS) improvements – can be accomplished by incorporating mindfulness-based interventions (or mindfulness-based training) as an effective MCS enabler.

Design/methodology/approach

The authors have conducted an integrative literature review to synthesize the knowledge of the mindfulness, sustainability and MCS literatures with a specific focus on OHS.

Findings

The findings revealed that there is a dearth of research that has investigated the potential linkages between mindfulness, MCS and sustainability. While some studies have explored the role of MCS in promoting sustainability and corporate social responsibility concepts, as well as the linkages between mindfulness and sustainability, this paper specifically looked at how mindfulness-based interventions can be applied in the organizational context to enhance OHS sustainability outcomes.

Research limitations/implications

This paper introduces a framework that shows how mindfulness-based interventions, as a means of MCS, can be used to enhance desired OHS sustainability outcomes.

Originality/value

This paper extends the sustainability, mindfulness and MCS literature by explicating how mindfulness-based interventions can be used as one of the key MCS enablers that support sustainability and OHS outcomes. Accordingly, the authors argue that this is one of the few early review papers that have investigated the potential connections between mindfulness, sustainability and MCS in the OHS context.
Ethics, code of conduct and ethical climate: implications for human resource development
Authors: Alizadeh Amin , Dirani Khalil M. , Qiu Shaoping
Published: December 2020

Purpose

The purpose of this paper is twofold: first, to point out the importance of having an ethics-related course for human resource development (HRD) graduate programs; and second, to highlight HRD potential to minimize ethical misconducts through an ethical filter in organizations.

Design/methodology/approach

This paper is conceptual in nature. The authors used their own experiences in HRD programs, looked at HRD graduate programs’ curricula in different universities and reviewed literature on ethics and HRD to develop a conceptual model. The model is to guide future studies and identify the role of HRD practices to create an ethical climate in organizations.

Findings

In this paper, the authors illustrate the connection between HRD practices and ethical climate in organizations by providing a conceptual framework. In the concluding paragraphs, the authors provide a discussion, implications and recommendations for future studies.

Originality/value

The authors highlight the limited research conducted on how ethics and ethical dilemmas need to be represented in HRD practitioners’ activities and practices. Many graduate-level HRD students do not receive enough training on ethics, whereas it is their responsibility to help improve organizational ethical climate and educate and prepare human resources to minimize ethical misconducts and wrongdoings. The paper provides a framework for HRD practitioners to create a strong ethical climate in their organizations.
Understanding quotation extraction and attribution: towards automatic extraction of public figure’s statements for journalism in Indonesia
Authors: Purnomo W.P. Yohanes Sigit , Kumar Yogan Jaya , Zulkarnain Nur Zareen
Published: December 2020

Purpose

Extracting information from unstructured data becomes a challenging task for computational linguistics. Public figure’s statement attributed by journalists in a story is one type of information that can be processed into structured data. Therefore, having the knowledge base about this data will be very beneficial for further use, such as for opinion mining, claim detection and fact-checking. This study aims to understand statement extraction tasks and the models that have already been applied to formulate a framework for further study.

Design/methodology/approach

This paper presents a literature review from selected previous research that specifically addresses the topics of quotation extraction and quotation attribution. Research works that discuss corpus development related to quotation extraction and quotation attribution are also considered. The findings of the review will be used as a basis for proposing a framework to direct further research.

Findings

There are three findings in this study. Firstly, the extraction process still consists of two main tasks, namely, the extraction of quotations and the attribution of quotations. Secondly, most extraction algorithms rely on a rule-based algorithm or traditional machine learning. And last, the availability of corpus, which is limited in quantity and depth. Based on these findings, a statement extraction framework for Indonesian language corpus and model development is proposed.

Originality/value

The paper serves as a guideline to formulate a framework for statement extraction based on the findings from the literature study. The proposed framework includes a corpus development in the Indonesian language and a model for public figure statement extraction. Furthermore, this study could be used as a reference to produce a similar framework for other languages.
Corporate social responsibility reporting: meeting stakeholders expectations or efficient allocation of resources?
Authors: Rashid Afzalur
Published: December 2020

Purpose

This study aims to examine whether corporate social responsibility (CSR) reporting adds any value to the firm.

Design/methodology/approach

This study uses content analysis to capture the specific CSR-related attributes and to construct a CSR reporting index. The data is manually collected from 115 publicly listed firms on the Dhaka Stock Exchange. The companies audited financial statements were the source of data. This study uses an ordinary least square regression analysis to examine the relationship between CSR reporting and firm performance.

Findings

The results of this study show that firms’ involvement in CSR activities and related reporting has a significant positive influence on firm performance only under an accounting-based performance measure. However, firms’ involvement in CSR activities and related reporting has a significant negative influence on firm performance under a market-based performance measure.

Research limitations/implications

This study is subject to some limitations, such as the subjectivity or judgement associated in the coding process.

Practical implications

The findings of this study imply that firms may be involved in CSR reporting to meet the stakeholders’ expectations, CSR reporting does not necessarily increase the intrinsic value of the firm.

Originality/value

This study supports the stakeholder theory and contributes to the literature on the practices of CSR reporting in the context of developing countries.
The management (or lack thereof) of COVID-19 in Brazil: implications for human rights and public health
Authors: da Luz Scherf Erick , Viana da Silva Marcos Vinicius , S. Fachini Janaina
Published: December 2020

Purpose

The purpose of this paper is to explore how the COVID-19 pandemic has been managed in Brazil, especially at the Federal Administrative level, with the focus being on the implications for human rights and public health in the country.

Design/methodology/approach

The research is built on a qualitative design made up of a case-study and review of the literature and is based on inductive reasoning.

Findings

Main conclusions were that: by not making sufficient efforts to safeguard the lives of Brazilians or to strengthen public health institutions amid the pandemic, Bolsonaro’s Administration may be violating the rights to life and health, among others, by omission; it was demonstrated that the President has worked unceasingly to bulldoze anti-COVID-19 efforts, which can be better explained through the concepts of necropolitics and neoliberal authoritarianism.

Research limitations/implications

One of the limitations to this research is that this paper was not able to discuss more thoroughly which other human rights norms and principles (apart from the right to health, life and the duty to protect vulnerable populations) have possibly been violated amid the COVID-19 pandemic in the country. Overall, this research can help expand the literature on human rights in health management during and after emergency times.

Originality/value

This paper focuses on recent events and on urgent matters that need to be addressed immediately in Brazil. This study provides an innovative health policy/human rights analysis to build an academic account of the ongoing pandemic in the largest country in South America.
Enhancing employees’ knowledge sharing through diversity-oriented leadership and strategic internal communication during the COVID-19 outbreak
Authors: Lee Yeunjae , Tao Weiting , Li Jo-Yun Queenie , Sun Ruoyu
Published: December 2020

Purpose

This study aims to examine the effects of diversity-oriented leadership and strategic internal communication on employees’ knowledge-sharing behavior during a crisis situation, coronavirus (COVID-19) outbreak in particular. Integrating knowledge sharing research with internal crisis communication literature as well as self-determination theory, the mediating roles of employees’ intrinsic needs satisfaction are also identified.

Design/methodology/approach

An online survey was conducted with 490 full-time employees in the USA across industry sectors during the COVID-19 outbreak.

Findings

Results suggest that diversity-oriented leadership contributes to transparent internal communication during a crisis and increases employees’ satisfaction of autonomy, competence and relatedness needs. Transparent internal communication also increases employees’ intrinsic needs satisfaction, which in turn fosters their job engagement and knowledge-sharing behavior during the crisis.

Originality/value

This study is one of the earliest studies to demonstrate the effectiveness of diversity-oriented leadership and strategic internal crisis communication in enhancing employees’ knowledge-sharing behavior, especially in the context of COVID-19.
Organizational adoption of 3D printing technology: a semisystematic literature review
Authors: Ukobitz Desiree Valeria
Published: December 2020

Purpose

Three-dimensional (3D) printing (3DP) offers a promising value proposition across multiple manufacturing industries. Despite the variety of production benefits the technology entails, its rate of adoption is still low compared to industry forecasts. In face of this challenge, industry as well as academia requires more information and guidance. This review aims to examine the characteristics of the existing body of research on the organizational adoption of 3DP as well as its underlying theoretical concepts. The most common criteria driving adoption will be derived, such as to facilitate the managerial decision-making process. Pathways for future research will be presented.

Design/methodology/approach

This study underlies a bibliometric literature review and additionally applies content analysis to systematically investigate the existing body of research and group decision criteria along the four major pillars of strategic decision-making.

Findings

The contributions of this paper are threefold. First, the bibliometric analysis reveals interesting aspects of the existing body of research. The most prominent characteristics of the contemporary literature are reflected along descriptive indicators, such as industry, method, model, origin, research outlet or adoption drivers, thus granting relevant insights into academia and practice. Second, the most notable adoption models are carefully analyzed on their inherent attributes and their application fit for the context of organizational 3DP adoption. Findings, for instance, revealed the dominance of diffusion of innovation (DOI) across the existing body of research and divulge that this construct is generally applied in combination with user-centered decision frameworks to yield more precise results. Third, an ample range of opportunities for future research are detected and thoroughly explained. Among others, the authors identified a clear lack of information on the impact environmental variables and contingency factors exerted on the organizational adoption of 3DP. Guidance in relation to the sourcing of industry data, usage of adoption frameworks and avenues for future scientific projects is supplied.

Originality/value

This study represents the first semi-systematic literature review on the organizational adoption of 3DP. Thus, it not only offers a valuable evaluation guide for potential adopters but also determines a future research agenda.

Authors: N. Parthasarathi , K.S. Satyanarayanan
Published: December 2020

Purpose

Technological innovations in the construction field correspond to a wider revolution in metropolitan life and in structural design. With the demand for advanced concrete technology, the introduction of new reinforced materials in concrete, namely, iron, steel and other reinforcing elements. Reinforcement in concrete is developed in the centuries back and several advancements are being stirred to improvise the properties of the concrete through reinforcements. On the basis of this finding from the earlier research studies, a reinforcement methodology is practiced on the current study to investigate the deflection of the M30 mix concrete frame under thermal load conditions.

Design/methodology/approach

For the examination, corner and the middle frame are considered with the reinforcement provided on four zones with 16-mm diameter for compression and 8-mm diameter is used for the stirrup at 150 mm c/c spacing. The load is applied to the column with live and wall load of 3.5 kN/m and 14.7KN/m. The experimentation is carried out by the finite element analysis strategy in ABAQUS simulation software with five test conditions with the bare frame at single, two and three-bay infill. The model of the frame is developed and meshed with the meshing type of C3D8T under 8-node thermally coupled brick mesh type for the mesh size of 25 mm.

Findings

From the simulation outcome, the effect of thermal gradient on the reinforced concrete is analyzed and its structural properties are plotted as performance graphs in the result section.

Originality/value

Under the thermal load condition, the model is simulated for 180 min for five different cases and analyzed the deflection parameters such as deformation, stress and failure rate.

Authors: Bonamigo Andrei , Frech Camila Guimarães
Published: December 2020

Purpose

This study aims to recognize industry 4.0 opportunities and challenges associated with the co-creation of value in industrial services and to propose a theoretical framework for smart industrial services systems.

Design/methodology/approach

The authors carried out a systematic literature review based on the systematic search flow method; thereafter, the authors used the content analysis proposed by Bardin (2011) to analyze the resulting portfolio.

Findings

The authors identified a total of five industry 4.0 opportunities and five challenges for co-creating value in industrial services. Drawing upon these findings, this paper builds a theoretical framework for the smart industrial services system, in which the industry 4.0 opportunities arise from the digitally mediated inter-firm interactions and the challenges related to the resources of this system.

Research limitations/implications

This study may not have enabled a complete coverage of all existing peer-reviewed articles in the field of value co-creation in industrial services associated with the industry 4.0 technologies. Also, the framework is constrained by being theoretical rather than empirically grounded.

Practical implications

The findings give managers support to devise strategies for overcoming the barriers that impede them from taking advantage of the opportunities offered by industry 4.0 for co-creating value in industrial services.

Originality/value

This paper’s uniqueness is to identify the industry 4.0 opportunities and challenges for value co-creation in the context of industrial services and to propose a framework for the smart industrial services system.

Authors: Enakrire Rexwhite Tega
Published: December 2020

Purpose

The purpose of this study is to investigate data literacy (DL) for teaching and learning in higher education institution, as data has become a crucial component in the accomplishment of task and decision-making in diverse sector, specifically higher education institutions (HEIs), where students’ records, results and research activities are managed in data form.

Design/methodology/approach

This study adopted the interpretive content/document analysis harvested from database of Web of Science in this study. The use of content/document analysis became essential to establish appropriate empirical evidence that relates to this study. This was to support the argument of detailed systematic examination, which the author establishes in the study. The interpretive content/document analysis was based on systematic literature review on specific objectives.

Findings

Findings indicates that DL is crucial in HEIs. Different types of data collection methods, such as rating scale, reporting, questionnaire, interview, observation, checklist, project, registration, assignment and performance test, were noticed in specific institutional cases. Subsequent conceptual and pedagogical foundations in processing data were obtain through continuous reskilling to acquire adequate knowledge and skills of DL. Social media and institutional repository are now used to digitise data. Different types of skills and abilities were used to search, analyse, adopt and share data in HEIs. This study recommends strategies of the use of different databases for data digitisation and creation of awareness on DL education in HEIs in Africa, specifically Nigeria.

Originality/value

This study is insightful with the understanding of DL in HEIs. The significance in this era of digital literacy become essential, as the need to have the knowledge and application of the use of data is important because of how it serves scholar in decision-making and planning in organisational productivity. The rationale towards this study on DL was on the basis that the world is a global village and without data, no organisation or HEIs could function adequately. Several types of data collected, such as rating scale, reporting, questionnaire, interview, observation, checklist, project, registration, assignment and performance test, have transformed institutional cases, for better and quality management operations. The subsequent conceptual and pedagogical foundations in processing data resulted in continuous reskilling, to sharpen learn and unlearn enterprise.
Blockchain ETFs: dynamic correlations and hedging capabilities
Authors: Pavlova Ivelina
Published: December 2020

Purpose

In this paper, the authors examine the interconnectedness of four blockchain exchange-traded funds (ETFs) with other financial markets, such as stocks and cryptocurrencies.

Design/methodology/approach

A multivariate dynamic conditional correlation model is used to model the relationship of blockchain ETFs with equity and cryptocurrency markets. Risk-minimizing hedge ratios are calculated following the methods used in studies by Kroner and Sultan (1993) and Sadorsky (2012).

Findings

The empirical results show a high degree of correlation of blockchain ETF returns with returns of the NASDAQ Composite Index, while the level of comovement with Bitcoin is relatively low.

Research limitations/implications

The results imply that blockchain ETFs may be suitable for hedging purposes in a portfolio holding Bitcoin. Furthermore, investing in blockchain ETFs appears similar to investing in NASDAQ.

Originality/value

To the best of the authors’ knowledge, no studies have investigated the dynamic relationship of blockchain ETFs and other financial assets.
What does labor displacement mean for management consulting firms?
Authors: Ribes Edouard
Published: December 2020

Purpose

This study aims to empirically investigate the effects of labor displacement on US management consulting (MC) firms.

Design/methodology/approach

This paper leverages standard linear regressions to identify and discuss correlations between progresses made in terms of labor displacement and the evolution of MC firms performance indicators.

Findings

In the context of US MC practices, the study shows that for every percent of work displaced, production costs are reduced by $3.7/h on average. It also highlights that as prices also go down by $3.3/h on average per percent of work displaced, off/near-shoring increases MC practices profitability. Displacing labor is yet a transformation that occurs mainly in very large firms (i.e. more than 1,000+ employees) and its full potential takes more than 4–5 years to realize.

Originality/value

This study provides new empirical benchmarks of the effect of labor displacement on MC firms. This study shows how long off/near-shoring takes to reach its full maturity.
Predicting employees’ engagement in environmental behaviours with supply chain firms
Authors: Amin Izzat , Zailani Suhaiza , Rahman Muhammad Khalilur
Published: December 2020

Purpose

The aim of this study is to investigate the employee perceptions of organizational support for environmental behaviours and its impact on innovative environmental behaviours and frequency of involvement in upstream oil and gas supply chain management. The study also examines a new area where environmental work culture has been introduced as a facilitator on the relationship between employees’ perceptions and engagement in supply chain management.

Design/methodology/approach

Self-administered questionnaires were used for collecting data from supply chain managers in production arrangement contractor and service provider company in Kuala Lumpur. Partial least squares was used for data analysis.

Findings

The findings reveal that supervisory support for environmental initiatives and environmental training is positively related to employees’ perception of organizational support for environmental behaviours, while rewards provided by the organization for environmental behaviours are not associated with it. The employees’ perceptions of organizational support for environmental behaviours have a significant impact on employees’ engagement in environmental behaviours in both forms of employees’ frequency of involvement and employees’ innovative environmental behaviours. The findings also show that environmental work culture moderates positively the impacts of organization’s support practices (supervisory support for environmental initiatives and rewards provided by the organization for environmental) on employees’ perception of organizational support for environmental behaviours.

Originality/value

The study critically examines the possible impact of enablers of engagement in environmental behaviours and how employees’ perceptions of organizational support reflect their engagement towards environmental behaviours of the organizational practices. The findings are useful for supply chain management practitioners in terms of exerting environmental behaviours and facilitating employees’ environmental behaviours in the upstream oil and gas supply chain management sector.
Federal intervention of police under section 14141 – a state-of-the-art literature review
Authors: Ostrowe Jason W.
Published: December 2020

Purpose

The purpose of this state-of-the-art review is to explore the empirical literature on federal intervention of police under 42 USC Section 14141.

Design/methodology/approach

A five-stage scoping review of the empirical literature related to 14141 was conducted through searches of scholarly databases and gray literature.

Findings

This scoping review revealed 21 empirical studies of 14141 published between 2002 and 2020 in criminal justice, criminology, legal and gray literature. Researchers employed various methodologies and designs to study 14141 reflecting the complexity of evaluating a multistage and multi-outcome federal intervention of police. The success of 14141 to reform police agencies is mixed. The empirical evidence suggests that application of this law is fraught with trade-offs and uncertainties including de-policing, increased crime and organizational difficulties in sustaining reform. Overall, more research would assist in understanding the efficacy of this federal mechanism of police accountability and reform.

Originality/value

This review is the first synthesis of the empirical literature on 14141. In consideration of the current national police crisis, findings help illuminate both what is known about federal intervention and areas for future research.
Making sense of cost-consciousness in social work
Authors: Bukh Per Nikolaj , Christensen Karina Skovvang , Svanholt Anne Kirstine
Published: December 2020

Purpose

This paper aims to explore how the introduction of new accounting information influences the understandings of cost-consciousness. Furthermore, the paper explores how managers use accounting information to shape organizational members’ understanding of changes, and how focusing on cost-consciousness influence professional culture within social services.

Design/methodology/approach

The paper is based on a case study, drawing on sensemaking as a theoretical lens. Top management, middle management and staff specialists at a medium-sized Danish municipality are interviewed.

Findings

The paper demonstrates how accounting metaphors can be effective in linking cost information and cost-consciousness to operational decisions in daily work practices. Further, the study elucidates how professionalism may be strengthened based on the use of accounting information.

Research limitations/implications

The study is context specific, and the role of accounting in professional work varies on the basis of the specific techniques involved.

Practical implications

The paper shows how managers influence how professionals interpret and use accounting information. It shows how cost-consciousness can be integrated with social work practices to improve service quality.

Originality/value

The paper contributes to the literature on how accounting information influences social work. To date, only a few papers have focused on how cost-consciousness can be understood in practice and how it influences professional culture. Further, the study expands the limited accounting metaphor research.
Perceptions of safety among visitors to China: feeling safe in an unfamiliar environment
Authors: Zou Yongguang , Mawby Rob I.
Published: December 2020

Purpose

The purpose of this paper is to address four questions: Firstly, how do tourists perceive safety from crime, specifically from robbery or violence, alongside other safety concerns? Secondly, are those who are concerned about crime also concerned about other threats to their well-being? Thirdly, how are their perceptions of safety affected by their perceptions of the local community? Finally, how are their perceptions affected by their personal and touristic characteristics?

Design/methodology/approach

Findings

Firstly, tourists did not generally see crime, specifically robbery or violence, as a problem; secondly, there was only a weak relationship between concern about crime and concern about other threats to their well-being; thirdly, in contrast, their perceptions of safety were strongly affected by their perceptions of the local community; and finally, their perceptions were affected by their personal and touristic characteristics, but not necessarily in the ways suggested by earlier research.

Research limitations/implications

The research sample was small and the questionnaire short. Only English-speaking visitors were included.

Practical implications

The tourism sector needs to appreciate role of local people in engendering feelings of safety.

Social implications

The attitude of the local community and their relationship with tourists is fundamental to helping visitors feel safe.

Originality/value

This is the first criminological paper to compare fear of crime with the other safety issues confronting tourists and to relate these concerns to relationships with host community.
An empirical investigation of factors influencing the environmental reporting quality: evidence from France
Authors: Moalla Marwa , Salhi Bassem , Jarboui Anis
Published: December 2020

Purpose

This study empirically tests a comprehensive set of relevant factors to explain environmental reporting quality. This study aims to understand whether environmental assurance has a direct effect on “environmental reporting quality”. In addition, this study also aims to examine the relationship between corporate governance and the quality of environmental reporting as measured by voluntary and timely reporting.

Design/methodology/approach

A number of econometric techniques are used including panel data specifications using a sample of French listed companies in SBF120 for the period 2012–2017.

Findings

The results demonstrate that the presence of an environmental audit committee and the size of the environmental external assurance firm has a significant effect on the level of voluntary reporting of environmental information. The results also reveal that the presence of the environmental audit committee, as well as the corporate social responsibility (CSR) committee, the size of the environmental external assurance and corporate governance index, affect the timely environmental reporting.

Research limitations/implications

This study helps all market participants to more comprehensively evaluate the quality of environmental reporting in the French context and highlights whether various factors could affect the quality of the environmental information disclosed using a multi-theoretical framework.

Originality/value

This paper fills the gap in the literature by highlighting an unexplored field of literature about the quality of environmental reporting by linking on the division of the quality of environmental information reporting into sub-dimensions (voluntary reporting and timely reporting) in the French context. To the knowledge, no empirical study has been done on the timely reporting of environmental information in the French context or other contexts. The originality of the work consists of the fact that it is one of the first works that deal with the relationship between environmental external assurance, corporate governance and the quality of environmental reporting.
Generation control of isolated small hydro power plant by using DECSA optimized FPI controller
Authors: Nayak Jyoti Ranjan , Shaw Binod , Dewangan Neeraj Kumar
Published: December 2020

Purpose

In this work, generation control of an isolated small hydro plant (SHP) is demonstrated by applying optimal controllers in speed governor and hydraulic turbine system. A comparative analysis of application of fuzzy PI (FPI) and PID controller is conferred for generation control (both power and terminal voltage) of an SHP. The controllers are designed optimally by using crow search algorithm (CSA) and novel hybrid differential evolution crow search algorithm (DECSA). The purpose of this paper is to settle the voltage and real power to improve the quality of the power.

Design/methodology/approach

In this work, the controllers (PID and FPI) are implemented in speed governor and excitation system of SHP to regulate power and terminal voltage. Differential evolution and CSA are hybridized to enhance the performance of controller to refurbish the power and terminal voltage of SHP.

Findings

The proposed DECSA algorithm is applied to solve ten benchmark functions, and the effectiveness of DECSA algorithm over CSA and DE is demonstrated in terms of best value, mean and standard deviation. CSA and DECSA algorithms optimized controllers (PID and FPI) are used to design SHP with the capability to contribute power and voltage of better quality. The comparative analysis to substantiate the competence of DECSA algorithm and FPI controller is demonstrated in terms of statistical measures of power and voltage of SHP. Robustness analysis is performed by varying all system parameters to prove the effectiveness of the proposed controller.

Originality/value

The proposed algorithm and FPI controller are applied individually to improve the quality of the power of SHP. DE, CSA and DECSA algorithms are implemented to solve benchmark equations. The solutions of all benchmark equations contributed by DECSA algorithm is converged rapidly and having minimum statistical measures as compared to DE and CSA algorithms. The DECSA algorithm and FPI controller are proposed with superior competence to enhance the generator performances by conceding undershoot, overshoot and settling time of power and terminal voltage. DECSA-based FPI controller contributes a noticeable improvement of the performances over other approaches.
Ownership type and earnings gap decomposition: Evidence from the Ghanaian labor market
Authors: Botchway Ebo , Asiedu Kofi Fred
Published: December 2020

We present evidence of sector earnings gap decomposition in the Ghanaian labor market for the period 2009–2015. With a sample of 200 workers from state‐owned enterprises (SOEs) and 250 from privatized enterprises (PEs), we use the Mincerian wage equation, with the Oaxaca–Blinder and Juhn–Murphy–Pierce decompositions on earnings, and observe that the two ownership categories differ regarding personal characteristics and institutional factors, with employees in PEs receiving a wage premium (64%) over their SOE counterparts. In addition, employee observed characteristics explain only 36% of the earnings differential. The PE‐SOE differential is small at the top quartiles compared with previous studies. However, individuals at the bottom of the wage distribution in the public sector earn far lower than their counterparts in the private sector, signaling that low‐level SOE workers have not gained much despite the single spine salary structure policy initiated by the Government in 2008 to bridge the wage gap. This study contributes to wage analysis and decomposition by focusing on individual and institutional factors—personal characteristics, sector, and government policy—that are traditionally not combined in extant literature.
The Craft of Anne Ryan's Collages
Authors: Richmond Susan
Published: December 2020

Between 1948 and 1954, Anne Ryan produced over 400 small‐scale collages out of worn fabrics and handmade paper. Although this work earned her a fruitful affiliation with the Betty Parsons Gallery in New York, its ‘feminine’ delicacy distinguished it from the bold styles generally associated with the artist's abstract expressionist peers. Revisiting the presupposition of a ‘feminine’ touch, this essay assesses the collages in light of Ryan's expertise as a sewer. Drawing from feminist theories on the significance of everyday embodied knowledge, it is argued that the artist defined the limits of her practice through careful material and tactile choices, demonstrating what is proposed to be a craft expertise engrained over a lifetime of handling threads and fabrics. Such claims, in turn, have broader bearing on how we continue to write about the relationship between modernist art and the structures, skills, and habits of the domestic everyday.
Neoproterozoic Crustal Reworking and Growth in the Zhangbaling Uplift, Tan–Lu Fault Zone: Evidence from the Feidong Complex and Zhangbaling Group
Authors: NIU Manlan , CAI Qianru , WU Qi , YUAN Xiaoyu , SUN Yi , LI Xiucai , LI Chen , ZHU Guang , LI Zhensheng , ZHANG Shuai
Published: December 2020

Intensive mid‐Neoproterozoic magmatism is the salient feature of the Yangtze Block, preserving abundant information about crustal reworking and growth. Zircon U–Pb–Lu–Hf isotope analysis was performed on material from the Feidong Complex (FDC) and Zhangbaling Group (ZBLG) of the Zhangbaling Uplift, in order to determine the age and magmatic source of the Neoproterozoic igneous rocks as well as the detrital provenance for the sedimentary rocks, to further provide important data for understanding the mid‐Neoproterozoic crustal evolution of the Northeast Yangtze Block. The amphibolite and gneissic granites in the Feidong Complex (FDC) gave similar protolith ages of 782–776 Ma. The synmagmatic zircons exhibited variable negative ∊Hf(t) values of –26.9 to –8.3. Early (ca. 2.4 Ga) to late Paleoproterozoic (ca. 2.0–1.9 Ga) inherited zircons were found in the gneissic monzogranite, with negative ∊Hf(t) values of –11.2 to –7.2, indicating strong reworking of the ancient crustal materials of the Northeast Yangtze Block. Whereas the amphibolites represent minor crustal growth through emplacement of continental rifting‐related mafic magmas. The quartz–keratophyres in the Xileng Formation of the ZBLG in contrast systematically yield young protolith crystallization ages of 754–727 Ma with high ∊Hf(t) values of –2.0 to +5.6, indicating their derivation from the reworking of juvenile crustal materials. The detrital zircons from the metasiltstone in the Beijiangjun Formation yield variable 206Pb/238U ages (871–644 Ma) with a peak age at 741 ± 11 Ma and ∊Hf(t) values of –4.3 to +5.3, which is consistent with those of the Xileng Formation, but distinct from the FDC, indicating that the provenance of the metasiltstone is primarily the underlying Xileng Formation. The mid‐Neoproterozoic igneous and sedimentary rocks of the Zhangbaling Uplift were products from continental rifting zones along the northern margin of the Yangtze Block, situated in different positions from the Susong Complex and the Haizhou Group. The transition from ancient to juvenile crustal sources for felsic magmatic rocks is attributed to gradually increased crustal extension during continental rifting.

Home range dynamics and movement are central to a species' ecology and strongly mediate both intra‐ and interspecific interactions. Numerous methods have been introduced to describe animal home ranges, but most lack predictive ability and cannot capture the effects of dynamic environmental patterns, such as the impacts of air and water flow on movement.

Here, we develop a practical, multi‐stage approach for statistical inference into the behavioural mechanisms underlying how habitat and dynamic energy landscapes—in this case how airflow increases or decreases the energetic efficiency of flight—shape animal home ranges based around central places. We validated the new approach using simulations, then applied it to a sample of 12 adult golden eagles Aquila chrysaetos tracked with satellite telemetry.

The application to golden eagles revealed the effects of habitat variables that align with predicted behavioural ecology. Further, we found that males and females partition their home ranges dynamically based on uplift. Specifically, changes in wind and sun angle drove differential space use between sexes, especially later in the breeding season when energetic demands of growing nestlings require both parents to forage more widely.

This method is easily implemented using widely available programming languages and is based on a hierarchical multistate Ornstein–Uhlenbeck space use process that incorporates habitat and energy landscapes. The underlying mathematical properties of the model allow straightforward computation of predicted utilization distributions, permitting estimation of home range size and visualization of space use patterns under varying conditions.
Neuroimaging and Cognitive Evidence for Combined HIV‐Alcohol Effects on the Central Nervous System: A Review

Alcohol use disorder (AUD) among people living with HIV (PLWH) is a significant public health concern. Despite the advent of effective antiretroviral therapy, up to 50% of PLWH still experience worsened neurocognition, which comorbid AUD exacerbates. We report converging lines of neuroimaging and neuropsychological evidence linking comorbid HIV/AUD to dysfunction in brain regions linked to executive function, learning and memory, processing speed, and motor control, and consequently to impairment in daily life. The brain shrinkage, functional network alterations, and brain metabolite disruption seen in individuals with HIV/AUD have been attributed to several interacting pathways: viral proteins and EtOH are directly neurotoxic and exacerbate each other’s neurotoxic effects; EtOH reduces antiretroviral adherence and increases viral replication; AUD and HIV both increase gut microbial translocation, promoting systemic inflammation and HIV transport into the brain by immune cells; and HIV may compound alcohol’s damaging effects on the liver, further increasing inflammation. We additionally review the neurocognitive effects of aging, Hepatitis C coinfection, obesity, and cardiovascular disease, tobacco use, and nutritional deficiencies, all of which have been shown to compound cognitive changes in HIV, AUD, and in their comorbidity. Finally, we examine emerging questions in HIV/AUD research, including genetic and cognitive protective factors, the role of binge drinking in HIV/AUD‐linked cognitive decline, and whether neurocognitive and brain functions normalize after drinking cessation.
Empowering Australian insecticide resistance research with genetic information: the road ahead

Insecticides are important for chemical control of arthropod pests in agricultural systems but select for resistance as an adaptive trait. Identifying the genetic mechanism(s) underpinning resistance can facilitate development of genetic markers, which can be used in monitoring programs. Moreover, understanding of genetic mechanisms in a broader population genetic context can be used to infer the origins of resistance, predict the dynamics of resistance evolution and evaluate the efficacy of different management strategies. Transitioning genetic information successfully into practical solutions requires overcoming two major hurdles. Firstly, genetic mechanisms must be identified to develop genetic markers. Secondly, routine use of genetic markers is required to build substantial spatio‐temporal data on the distribution and frequency of resistance alleles. In this study, we demonstrate large knowledge gaps on the genetic mechanisms of insecticide resistances in Australia using eight established arthropod pests important to the grains industry: Bemisia tabaci (silverleaf whitefly), Frankliniella occidentalis (western flower thrips), Halotydeus destructor (redlegged earth mite), Helicoverpa armigera (cotton bollworm), Myzus persicae (green peach aphid), Plutella xylostella (diamondback moth), Tetranychus urticae (two‐spotted spider mite) and Thrips tabaci (onion thrips). Many resistances have not been characterised at the genetic level in most pests, even for chemical MoA groups with a long history of use in Australia. Moreover, monitoring of resistance is spatio‐temporally patchy, which precludes examination of long‐term trends or predictive modelling. We suggest that leveraging cumulative global knowledge of resistances to develop a priori candidate genes, and incorporation of genomic approaches, can help overcome the hurdles of embracing genetic information in resistance management. We highlight the recently invasive Spodoptera frugiperda (fall armyworm) as a case study where genetic markers and genomic approaches should prove useful in rapidly assessing the risk of this species to the Australian grains industry and other agricultural commodities. The uptake of genetic information into management can only occur once its benefit to empower insecticide resistance research is fully realised. Ultimately, the road ahead requires amalgamation of multifaceted data (genes, environment and spatio‐temporal replication) to better understand and predict the dynamics of resistance evolution.

Objective

To evaluate the dementia knowledge of allied health professionals and identify their specific learning needs.

Methods

An online survey was conducted with allied health professionals enrolled in the Understanding Dementia Massive Open Online Course, a free course open to anyone, worldwide. The primary outcome measure was the Dementia Knowledge Assessment Scale, assessed prior to course commencement.

Results

The survey was completed by 1591 participants. The mean dementia knowledge score was 35.0 (SD 8.4), with 13% (n = 207) achieving a target score of 45/50 or above, indicating comprehensive dementia knowledge. Key knowledge gaps were in the areas of dementia onset and non‐pharmacological management of behavioural and psychological symptoms of dementia.

Conclusions

Allied health professionals surveyed had significant gaps in dementia knowledge. Educators planning dementia curriculum for allied health professionals could consider addressing areas of knowledge related to the identified items, with view to providing a foundation for excellence in dementia care.
