What do we know about information security governance?
Authors: Schinagl Stef , Shahim Abbas
Published: February 2020

Purpose

This paper aims to review the information security governance (ISG) literature and emphasises the tensions that exist at the intersection of the rapidly changing business climate and the current body of knowledge on ISG.

Design/methodology/approach

The intention of the authors was to conduct a systematic literature review. However, owing to limited empirical papers in ISG research, this paper is more conceptually organised.

Findings

This paper shows that security has shifted from a narrow-focused isolated issue towards a strategic business issue with “from the basement to the boardroom” implications. The key takeaway is that protecting the organisation is important, but organizations must also develop strategies to ensure resilient businesses to take advantage of the opportunities that digitalization can bring.

Research limitations/implications

The concept of DSG is a new research territory that addresses the limitations and gaps of traditional ISG approaches in a digital context. To this extent, organisational theories are suggested to help build knowledge that offers a deeper understanding than that provided by the too often used practical approaches in ISG research.

Practical implications

This paper supports practitioners and decision makers by providing a deeper understanding of how organisations and their security approaches are actually affected by digitalisation.

Social implications

This paper helps individuals to understand that they have increasing rights with regard to privacy and security and a say in what parties they assign business to.

Originality/value

This paper makes a novel contribution to ISG research. To the authors’ knowledge, this is the first attempt to review and structure the ISG literature.
RegBoost: a gradient boosted multivariate regression algorithm
Authors: Li Wen , Wang Wei , Huo Wenjun
Published: February 2020

Purpose

Inspired by the basic idea of gradient boosting, this study aims to design a novel multivariate regression ensemble algorithm RegBoost by using multivariate linear regression as a weak predictor.

Design/methodology/approach

To achieve nonlinearity after combining all linear regression predictors, the training data is divided into two branches according to the prediction results using the current weak predictor. The linear regression modeling is recursively executed in two branches. In the test phase, test data is distributed to a specific branch to continue with the next weak predictor. The final result is the sum of all weak predictors across the entire path.

Findings

Through comparison experiments, it is found that the algorithm RegBoost can achieve similar performance to the gradient boosted decision tree (GBDT). The algorithm is very effective compared to linear regression.

Originality/value

This paper attempts to design a novel regression algorithm RegBoost with reference to GBDT. To the best of the knowledge, for the first time, RegBoost uses linear regression as a weak predictor, and combine with gradient boosting to build an ensemble algorithm.
Analysis of sustainability presence in Spanish higher education
Authors: Sánchez-Carracedo Fermín , Sureda Carbonell Bàrbara , Moreno-Pino Francisco Manuel
Published: February 2020

Purpose

This paper aims to analyze the presence of sustainability in 16 Spanish higher education curricula in the fields of education and engineering.

Design/methodology/approach

The methodology uses two instruments: sustainability map and sustainability presence map. These instruments enable analysis of the number of subjects that develop sustainability and the sustainability presence level in each curriculum; identification of what domain levels of the learning taxonomy sustainability is most developed; and analysis of whether a correlation exists between the sustainability presence and the number of subjects that develop sustainability in each curriculum.

Findings

A wide variety of subjects develop sustainability in a given degree, depending on the university. The presence of sustainability is more homogeneous in education degrees than in engineering degrees. Education degrees have a greater presence of sustainability in the lower domain levels of taxonomy, while in engineering degrees the lower levels of taxonomy have a lower presence of sustainability than the higher levels. Finally, a correlation appears to exist between the number of subjects that develop sustainability in the curriculum and the sustainability presence. However, engineering degrees seem to need fewer subjects than education degrees to achieve the same degree of sustainability presence.

Originality/value

This paper proposes a methodology to measure sustainability presence that can be applicable to the curricula of a higher education degree if the corresponding sustainability map is available. To the authors’ knowledge, this is the largest study yet conducted to analyze the presence of sustainability in different higher education curricula.
Fear of terrorism and its correlates in young men and women from the United States and South Korea
Authors: Hong Fang , Lin Yijing , Jang Mikyung , Tarullo Amanda , Ashy Majed , Malley-Morrison Kathleen
Published: February 2020

Purpose

The purpose of this study was to examine associations between fear of terrorism and several predictors (gender and nationality) and outcomes (moral disengagement, authoritarianism, aggression and social anxiety) in the USA and South Korean young adults. Of particular interest were the potential moderating and mediating roles of moral disengagement between fear of terrorism and the other outcomes.

Design/methodology/approach

Samples of 251 college students from the USA and 211 college students from South Korea completed survey packets including measures of fear of terrorism, moral disengagement, authoritarianism, aggression and social anxiety.

Findings

US participants expressed greater concern about a terrorist threat to their country, while South Koreans worried more about terrorist threats to their family or themselves. Females in both countries reported greater fear of terrorism and social anxiety. In both countries, fear of terrorism was associated with aggression, social anxiety and moral disengagement. Mediation analyses showed that fear of terrorism exerted a significant direct effect and an indirect effect via moral disengagement on aggression and authoritarianism in the US sample. Moderation analyses revealed that moral disengagement moderated the relationship between fear of terrorism and social anxiety in the Korean sample.

Research limitations/implications

This study has the common limitations of cross-sectional studies; i.e. it cannot prove causal relationships.

Practical implications

The findings support Albert Bandura’s view that efforts to address the excesses of counterterrorism and other negative outcomes of fear of terrorism, attending to issues of moral disengagement may be helpful.

Originality/value

The authors findings provide support for the view that fear of terrorism is associated with negative psychological and social outcomes and that moral disengagement can play an important role in those negative outcomes. Moreover, it adds to evidence that the negative role of moral disengagement shows considerable generalizability across gender and two very different cultures.

Financial exclusion as a consequence of counter-terrorism financing
Authors: Malakoutikhah Zeynab
Published: February 2020

Purpose

The purpose of this paper is to analyse the unintended consequences, financial exclusion, of counter-terrorism financing regulations in terms of their impact on financial inclusion and, consequently, the creation of an ineffective counter-terrorism financing framework. A further aim is to make recommendations to mitigate these unintended consequences.

Design/methodology/approach

This subject is examined by using the practices of a range of countries and organisations. The interdisciplinary approach of the paper is highlighted, which comprises criminal law, banking law, international law and human rights law.

Findings

Financial exclusion is a focal point that results in ineffective counter-terrorism measures which are caused mostly by the formal financial sector, in particular, the banking system. The financial exclusion also leads to counter-productive counter-terrorism financing through a low risk-appetite, de-risking, de-banking, financial exclusion and using unregulated or less-regulated and supervised financial systems.

Originality/value

No article comprehensively analyses financial exclusion as a consequence of counter-terrorism financing framework. The paper examines the process of counter-terrorism financing regulations, which leads to financial exclusion. In addition, the impact of financial exclusion on all relevant actors, such as individuals, correspondent banking relationships, money and value transfer services, charities and virtual currencies, is examined.

Authors: Kalovya Omari Zuberi
Published: February 2020

Purpose

The paper aim at empirical examination of the predictors of the occupational fraud losses by drawing insights evolving fraud theoretical frameworks.

Design/methodology/approach

A survey of fraud professionals and witnesses in Tanzania was administered to collect data which profiled perpetrators, victims, losses and elements of financial pressure, opportunity, capability and rationalization. A total of 109 responses were analyzed through ordinary least squares regressions.

Findings

The study found that apart from organizational and individual level predictors, interactive fraud elements, incorporating situational factors and moderated by fraudster’s history have significant influence in explaining the magnitude of observed fraud losses.

Research limitations/implications

The findings of this study have implications for researchers and managers in business in enhancing understanding of the predictors of the occupational fraud losses in general, and specifically in streamlining the efforts to prevent, detect and resolve fraud on timely basis so as to minimize the frequencies and magnitudes of occupational fraud losses.

Originality/value

The study provides unique insights through empirical analysis that draws predictors from both prior literature and existing fraud theoretical frameworks. Unlike other studies relative importance of each individual, organizational and situational factors including interaction effects of key variables, are discussed.

Authors: Zeferino Emanuel Fernando Samasseca , Mpofu Khumbulani , Makinde Olasumbo Ayodeji , Ramatsetse Boitumelo Innocent , Daniyan Ilesanmi Afolabi
Published: February 2020

Purpose

The determination of the appropriate site for the location of a research institute represents a multi-criteria problem which requires a scientific approach for decision-making. The research centre in this study is an institute that intends to carry out the state-of-the-art research activities and provide the requisite skills to expedite and optimize the manufacturing of rail cars in South Africa. Hence, the selection of a suitable and conducive location capable of achieving these aforementioned objectives in an effective manner is a problem which requires scientific justification for the allocation of the weights and biases. In light of this, using various decision techniques, this paper aims to establish a suitable framework for the location selection of the research institute which is capable of meeting the short- and long-term objectives of the institute.

Design/methodology/approach

This aim was achieved by ascertaining the suitability of potential location alternatives using the factor rating (FR) and centre of gravity (CoG) technique.

Findings

The CoG revealed that any location within the longitude of 28.28 and latitude of −25.75 (with a Cartesian coordinate position of 5053.62; 2718.69) is suitable for the research institute, while the result of the FR/weighted score matrix revealed that location J3 with a weighted score of 72.6% is the most suitable location for the research institute with the longitude of 5053.62 and latitude of 2718.69.

Practical implications

The results of this paper helped decision-makers in locating the given research institute which is currently operational.

Originality/value

The present study is focussed on the application of location decision techniques in the research institute scenario. The combination of FR and CoG techniques for the selection of the most suitable location for a research institute amidst conflicting criteria has not been widely reported by the existing literature.
Structural equation modelling – FTOPSIS approach for modelling barriers to product development in medical device manufacturing industries
Authors: Kirkire Milind Shrikant , Rane Santosh B. , Abhyankar Gayatri Jayant
Published: February 2020

Purpose

The purpose of this paper model and prioritizes barriers to product development in medical device manufacturing industries using an integrated “structural equation modelling” (SEM) and “fuzzy technique for order performance by similarity to ideal solution” (FTOPSIS) framework.

Design/methodology/approach

Barriers to medical device development (MDD) are adopted from literature. The initial structural model is proposed, exploratory factor analysis and confirmatory factor analysis are used to determine factor loading and model fit, respectively. Further, FTOPSIS is used to rank the barriers and sensitivity analysis is carried to check the robustness of results. The results are discussed in detail and the recommendations to overcome the barriers are presented.

Findings

Barriers analysed and prioritized in this research significantly hinder the MDD. The expert survey is used to develop an initial structural equation model of barriers to MDD, find the reliability and validity of the model. Based on the opinion of the experts, the barriers are divided into three categories – internal, policy and induced barriers. FTOPSIS is applied to rank and prioritize the barriers based on views from these three classes of experts. More reliance on imported devices leading to increased imports (B11) and lack of uniform regulatory standards (B6) are found to have the highest rank together, indicating these to be the most important barriers from the perspective considered here. Sensitivity analysis indicates that the factors are less sensitive to the weights of criteria further confirming the reliability of the initial solution.

Research limitations/implications

The prioritization of barriers may vary based upon experts. Policymakers, existing and new device developers need to give utmost importance to these barriers, which will help to accelerate the indigenous development of medical devices to overcome the present dependence on imports.

Practical implications

This paper demonstrates an integrated structural based modelling and prioritization technique for statistical modelling and prioritization of barriers to MDD. The results and recommendations will help policymakers and manufacturers to increase the indigenous share of medical devices. The integrated methodology can be effectively applied where the need for the combined quantitative and qualitative approach is there.

Originality/value

This paper demonstrates an effective structural based modelling and prioritization technique. It can be effectively applied in various fields, it will help policymakers and manufacturers to increase the indigenous share of medical devices.
Factors affecting dividend policy in manufacturing companies in Indonesia Stock Exchange
Authors: Wahjudi Eko
Published: February 2020

Purpose

The purpose of this paper is to analyze the variables that significantly affect dividend policy.

Design/methodology/approach

This research uses a type of comparative causal research (causal-comparative research), where the fact or event is identified as an influenced variable (dependent variable) and the variables that influence (independent variable) are investigated. In this study, the authors want to examine the effect of collateralizable assets, growth in net assets, liquidity, leverage and profitability of dividend policy by using quantitative approach. The data used are secondary data obtained from Indonesia Stock Exchange website with website address: www.idx.co.id.

Findings

The results showed that collateralizable assets have a negative, but not significant, effect on dividend policy. This shows that the high collateralizable assets do not affect the policy of the dividend of manufacturing companies. The second variable, growth in net assets, has a negative and significant effect on dividend policy. This shows that the higher growth in net assets will lower the dividend policy of manufacturing companies. Furthermore, the results show that liquidity has a negative and significant effect on dividend policy. This indicates that higher liquidity will lower the dividend policy of manufacturing companies. Furthermore, result that leverage has a negative and significant effect on dividend policy is obtained. This suggests that the higher leverage will lower the dividend policy of the manufacturing company. And lastly, profitability has a negative, but not significant, effect on dividend policy. This shows that high profitability does not affect dividend policy of manufacturing companies.

Originality/value

The authors contribute to prior research by providing the empirical evidence on the impact of collateralizable assets, growth in net assets, liquidity, leverage and profitability on dividend policy in Indonesia market as an emerging market.
The mediating effects of product innovation in relation between knowledge management and competitive advantage
Authors: Wahyono Wahyono
Published: February 2020

Purpose

The purpose of this paper is to examine the mediating effect of product innovation on the relation between the knowledge management and competitive advantage. To analyze the effect of knowledge management on innovation, the effect of knowledge management on competitive advantage and the effect of innovation on competitive advantage in small and medium enterprises in food products are taken into account.

Design/methodology/approach

The approach used in this study was quantitative approach. The population in this study was all the small and medium entrepreneurs of typical food products of Riau and Central Java Indonesia, which consisted of 238 business units: secondary data of Industry, Trade and Cooperative Service and SME Riau and Central Java Province at 2016. The data analysis method was structural equation modeling, using three measurement models (reflection of three research variables, equivalent to the first-order factor analysis).

Findings

Product innovation mediated the effect of knowledge management on the competitive advantage. It indicated that the higher the knowledge management, the higher the competitive advantage would be, if mediated by higher product innovation. The test results showed that knowledge management had positive and significant effect on product innovation. The positive effect showed that the better the knowledge management by the entrepreneurs of small and medium enterprises of typical food products of Riau, the better is the product innovation and vice versa.

Originality/value

This paper examines the mediating effects (using Sobel test) of product innovation on the relation between knowledge management and competitive advantage (no previous research on this relation), and the study is conducted on SMEs in Indonesia, especially in Riau and Central Java provinces. Previous studies on knowledge management and other factors affecting competitive advantage are also mostly performed on smaller samples, that is in one work unit or department. Although the variables were the same, this study was conducted on different sample units.
Presenting a legal and regulatory analysis of the United Arab Emirates’ past, present and future legislation on combating money laundering (ML) and terrorist financing (TF)
Authors: Naheem Mohammed Ahmad
Published: February 2020

Purpose

This paper aims to study the three levels of anti-money laundering (AML) and combating of terrorist financing (CTF) regulations that apply to banks and financial institutions listed within the country. The paper aims to determine risks arising from globalised financial centres within the United Arab Emirates (UAE) and potential improvements deficiencies that may otherwise serve as conduits for criminal and terrorist organisations. There is a significant body of literature that covers the advance of AML/CTF legislation in the Dubai-based free trade zone, the Dubai International Financial Centre (DIFC). Though free trade zones are scattered across the UAE, the DIFC has the highest foreign investment in the country with an expanded international network.

Design/methodology/approach

The UAE has made progress as part of its fight against money laundering (ML) and terrorist financing (TF). This paper studies the legislative stance by analysing the country’s AML/CTF laws. Also, the advances of global financial centres in the UAE have created layers of regulation, each regulator with their own set of rules. This paper attempts to study the regulations and the level of their enforcement to combat ML and TF.

Findings

This paper finds significant regulatory oversight in certain frameworks set within the UAE’s financial system. However, the paper finds secondary literature and evaluations conducted by international bodies that suggest some deficiencies within the mechanisms, that are being resolved by the country’s regulatory agencies. The UAE’s advancing network of financial institutions has created a global chain of monetary transfers, which offers some possibility of ML also extending to TF. Though the country has made progress, there remain a few flaws that can be exploited by criminal and terrorist organisations.

Practical implications

ML has the possibility to damage markets if allowed in excess. This is not the case with the UAE, and large unverified transactions are investigated by the regular authorities. ML is now a matter of concern when funds acquired through illegal means may be used to directly finance terrorism.

Originality/value

This paper tests the UAE’s mechanisms to combat ML and TF in the context of the country’s advancing of a global central financial market. There is a need to understand these regulations as investors within the UAE and abroad may sometimes face risk if ML/TF deficiencies are exploited by criminal and terrorist organisations. This paper provides an insight into the country’s infrastructure to combat ML and TF and also weighs its performance as per international standards and guidelines.
The art of conversation: design cybernetics and its ethics
Authors: Westermann Claudia
Published: February 2020

Purpose

The purpose of this paper to discuss ethical principles that are implicit in second-order cybernetics, with the aim of arriving at a better understanding of how second-order cybernetics frames living in a world with others. It further investigates implications for second-order cybernetics approaches to architectural design, i.e. the activity of designing frameworks for living.

Design/methodology/approach

The paper investigates terminology in the second-order cybernetics literature with specific attention to terms that suggest that there are ethical principles at work. It further relates second-order cybernetics to selected notions in phenomenology, pragmatism and transcendental idealism. The comparison allows for conclusions about the specificity of a second-order inquiry. In line with the thematic focus of this journal issue on the framing of shared worlds, the paper further elaborates on questions relating to the activity of designing “worlds” in which people live with others.

Findings

The paper highlights that a radical openness toward the future and toward the agency of others is inscribed in the conception of second-order cybernetics. It creates a frame of reference for conceiving social systems of all kinds, including environments that are designed to be inhabited.

Originality/value

The paper identifies an aesthetics grounded in the process of living-with-others as an ethical principle implicit in second-order cybernetics thought. It is an aesthetics that is radically open for the agency of others. Linking aesthetics and ethics, the paper’s contributions will be of specific value for practitioners and theoreticians of design. Considering second-order cybernetics as a practice generally dealing with designing, it also contributes to the wider second-order cybernetics discourse.
Understanding the role of individual differences in mobile SNS addiction
Authors: Gong Mingchuan , Xu Mengli , Luqman Adeel , Yu Lingling , Masood Ayesha
Published: February 2020

Purpose

The phenomenon of mobile social networking site (SNS) addiction has become increasingly severe nowadays and brings adverse outcomes to users’ daily life and work efficiency. However, there are relatively few research probes into the formation process of mobile SNS addiction behavior, and how demographic factors (e.g. gender and age) influence users’ addiction behavior. Adopting the stimulus–organism–response (S–O–R) framework, this study examines the effects of three types of technological functions (enjoyment, sociability and information value) on flow in relation to mobile SNS addiction. The authors further proposed gender and age as moderators, which play important roles in influencing the formation of mobile SNS addiction behavior.

Design/methodology/approach

This study examines the formation of mobile SNS addiction with a particular focus on the WeChat app. The authors use a field survey study conducted in China with 351 subjects of WeChat app users to examine thestudy model.

Findings

The results demonstrate that addictive behavior is determined by users’ flow states of using mobile SNS. The flow states, in turn, are influenced by three types of technological functions (enjoyment, sociability and information value). In addition, gender and age act as vital moderators in the model.

Originality/value

First, the authors empirically examine the formation of SNS addiction on the mobile device by adopting the S–O–R framework, which may enrich the addiction literature. Second, the authors reveal the moderating roles of age and gender in affecting the formation process of addiction behavior further. The findings of this research deepen our understanding of users’ addiction behavior. Third, the findings also offer rich insights to prevent mobile SNS addiction.
Compact electrothermal model of laboratory made GaN Schottky diodes
Authors: Górecki Krzysztof , Górecki Paweł
Published: February 2020

Purpose

The purpose of this paper is to propose a simple electrothermal model of GaN Schottky diodes, and its usefulness for circuit-level electrothermal simulation of laboratory-made devices is proved.

Design/methodology/approach

The compact electrothermal model of this device has the form of a subcircuit for simulation program with integrated circuit emphasis. This model takes into account influence of a change in ambient temperature in a wide range as well as influence of self-heating phenomena on dc characteristics of laboratory-made GaN Schottky diodes. The method of model parameters estimation is described.

Findings

It is shown that temperature influences fewer characteristics of GaN Schottky diodes than classical silicon diodes. The discussed model accurately describes properties of laboratory made GaN Schottky diodes. Additionally, the measured and computed characteristics of these diodes are shown and discussed.

Research limitations/implications

The presented model together with the results of measurements and computations is dedicated only to laboratory-made GaN Schottky diodes.

Originality/value

The presented investigations show that characteristics of laboratory-made GaN Schottky diodes visibly change with temperature. These changes can be correctly estimated using the compact electrothermal model proposed in this paper. The correctness of this model is proved for four structures of such diodes characterised by different values of structure area and a different assembly process.

Authors: Balkin David B. , Trevino Len J. , Fitza Markus , Gomez-Mejia Luis R. , Tadikonda Harsha
Published: February 2020

Purpose

The purpose of this study is to identify antecedent factors in addition to merit that contribute to the designation of first author on a publication. A second purpose is to provide knowledge of the significance and implications of being designated first author on a research article in the management discipline. A third purpose is to propose directions for further research.

Design/methodology/approach

The study consists of an empirical analysis of archival data gathered from 780 authors of 260 coauthored articles from top-tier journals and uses logit regression to analyze the data.

Findings

The empirical analysis shows that under certain conditions author need and author power are factors that combine with merit as antecedents to the designation of being the first author of an article.

Originality/value

To the best of the authors’ knowledge, this is the first empirical study that identified antecedent factors that contribute to first authorship beyond the prescribed factor of merit which professional norms in management assume is the one and only factor that contributes to being designated as first author.
Do consumers support the cross-border charitable activities as the same?
Authors: Tong Zelin , Li Tingting , Feng Wenting , Zhou Yuanyuan , Zhou Ling
Published: February 2020

Purpose

This study aims to investigate the impact of cross-border charitable activities on host- and home-country consumers based on the social identity theory.

Design/methodology/approach

Through an extensive literature review and two experimental designs, this study establishes the research framework and hypothesises the relationships between the constructs.

Findings

National power moderates the impact of cross-border charitable activities on host- and home-country consumers. In particular, compared to countries with high national power, countries with low national power undertaking cross-border charitable activities will receive more positive reactions from the host-country consumers, and, conversely, more negative reactions from the home-country consumers.

Research limitations/implications

From the consumer perspective, this study finds that brand cross-border charitable activities have different influences on consumers in different countries because of an identity transformation mechanism that exists between the “insiders” and the “outsiders”, which is different from the assumptions of western theories.

Practical implications

The findings provide insights for undertaking brand cross-border charitable activities.

Originality/value

Previous studies, which are based on social identity categorisation, assume that cross-border charitable activities have a more positive impact on home-country consumers than host-country consumers. However, this study adopts the research paradigm of social identity relationisation and draws an opposite conclusion, which not only expands the theory of local intergroup interaction, but also clarifies how brand cross-border charitable activities influence Chinese consumers.
Changes in commissioning home care: an English survey
Authors: Davies Sue , Hughes Jane , Davies Karen , Dalgarno Elizabeth , Jasper Rowan Elaine , Chester Helen , Roberts Amy , Challis David
Published: February 2020

Purpose

The purpose of this study is to examine changes in the nature, form and range of commissioning arrangements for home care.

Design/methodology/approach

Data from two discrete national surveys of English local authorities with social service responsibilities were used. In the first, undertaken in 2007, responses from 111 of the 151 local authorities (74%) were received; in the second, undertaken in 2017, responses from 109 local authorities (72%) were received. A combined data set of 79 complete cases, 52% of local authorities, was created. Percentage point differences across the two time periods were calculated and tested to identify significant changes and a systematic analysis of the free-text responses regarding intended changes to the commissioning process in each data set was undertaken.

Findings

Findings identified substantial changes in some aspects of the commissioning of home care in the 2007-2017 decade. Collaboration between stakeholders had increased, particularly regarding the identification of future needs. Improved conditions of service and remuneration for home care workers were evident within the commissioning process. Standardised charges for home care (regardless of time and day) had also become more widespread. Initiatives to prompt providers to deliver more personalised care were more evident.

Originality/value

This paper describes the evolution of commissioning arrangements for home care in localities in response to national policy initiatives. It provides guidance to commissioners in meeting the needs of current service users and emphasises the importance of collaboration with stakeholders, particularly providers, in securing future capacity.
Actors’ reflexivity and engagement in the formation of new accounting tools during university hybridization
Authors: Aleksandrov Evgenii
Published: February 2020

Purpose

This paper aims to investigate the unfolding dynamics and evolving processes relating to the formation of accounting tools by university actors. It answers the research questions: How do individual actors engage in the formation of new accounting tools during university hybridisation? Specifically, what forms of reflexivity do these actors display in various phases of university hybridisation?

Design/methodology/approach

This is a longitudinal case study of the development of new accounting tools in one Russian technical university from 2010 to 2016. It is based on an institutional work perspective, involving 29 interviews, documentary analysis, and observations of internal meetings relating to new accounting tools’ formation.

Findings

The findings show that academics themselves were gradually engaged in the marginalisation of academic demands in university governance in favour of managerialism via accounting. Nevertheless, the role of accounting morphed over time from a dysfunctional and negative carrier of managerial ideology and its domination, to what could arguably be considered a mediation device between academic and managerial demands. These dynamic processes and the role of accounting within them are explained by the constant challenge stemming from the involvement of several groups of actors in institutional work, which is often unpredictable and fluid due to the intricate play of plural reflexivities and actors’ identities during university hybridisation.

Originality/value

This paper advances the field by showing that the engagement and reflexivity of academics in the formation of accounting tools is not a “panacea” to deal with hybridisation within universities. The results highlight several obstacles, including variation in the reflexive capacities of actors within the university, leading to a reflexivity lag and reflexivity trap.
Super-resolution measurement method for passive wireless resonant surface acoustic wave sensor
Authors: Liu Boquan
Published: February 2020

Purpose

This study aims to use resonant surface acoustic wave (SAW) sensors, which have advantages in the harsh application environments, to measure different physical parameters such as temperature, pressure and force. For SAW sensors, the locality in measurement resolution by the effective time is poor, it cannot give the detailed results of SAW echoes.

Design/methodology/approach

To promote the application of SAW sensor, this paper proposes a convex program-based super-resolution measurement method to recover the missing spectral line and enhance frequency resolution.

Findings

The proposed method reduces the reliance on effective time and improves the measurement resolution of SAW sensors. The performance was validated by experiments.

Originality/value

The limited resolution capability restricts the benefit of SAW technology in harsh environments. The proposed method shed light on SAW measurement resolution increase, exploiting its full potential and leading to commercial applications.

Published: February 2020

Pulsed dye laser‐resistant port‐wine stains present a therapeutic challenge. The aim of this study was to evaluate the efficacy and safety of photodynamic therapy for treating these lesions. A total of 67 patients with pulsed dye laser‐resistant cervicofacial port‐wine stains were retrospectively assessed after undergoing photodynamic therapy mediated with a combination of hemoporfin and 532‐nm light. For objective evaluation of photodynamic therapy efficacy, first, the colorimetric changes in the port‐wine stain lesions were evaluated according to the L*a*b* color coordinate system, then the values of color changes (ΔE) and blanching rate were calculated. For subjective evaluation of improvement, photographs taken before and after photodynamic therapy were evaluated by three independent assessors blindly. Patient satisfaction was also used as a factor in the subjective evaluation. Adverse events were recorded after treatment. The median ΔE decreased significantly from the pretreatment value of 13.42 to 9.90 at the 2‐month follow up (P < 0.001). The median blanching rate of port‐wine stains was 28.04% after an average of 1.21 sessions of photodynamic therapy. Based on the overall visual assessment, 46.2% patients showed excellent or good levels of improvement (>50% color blanching). Adverse events were minimal, transient and self‐limiting. In conclusion, photodynamic therapy serves as an alternative means to treat pulsed dye laser‐resistant port‐wine stains.

Because broad genetic diversity has recently been detected in Torque teno sus viruses (TTSuV1 and TTSuVk2), the viral genome detection method needs to be improved to understand the prevalence of these viruses. Here, we established single PCR‐based detection methods for the TTSuV1 and TTSuVk2a genomes with newly designed primer pairs and applied them to investigate the prevalence of TTSuV1 and TTSuVk2a in Japanese pig populations. The results revealed that 98.2% and 81.7% of the pig farms tested positive for the TTSuV1 and TTSuVk2a genomes, respectively, indicating that both TTSuV1 and TTSuVk2a are widespread in Japan.
An overview of siderophore biosynthesis among fluorescent Pseudomonads and new insights into their complex cellular organization

Published: February 2020

Siderophores are iron‐chelating molecules produced by bacteria to access iron, a key nutrient. These compounds have highly diverse chemical structures, with various chelating groups. They are released by bacteria into their environment to scavenge iron and bring it back into the cells. The biosynthesis of siderophores requires complex enzymatic processes and expression of the enzymes involved is very finely regulated by iron availability and diverse transcriptional regulators. Recent data have also highlighted the organization of the enzymes involved in siderophore biosynthesis into siderosomes, multi‐enzymatic complexes involved in siderophore synthesis. An understanding of siderophore biosynthesis is of great importance, as these compounds have many potential biotechnological applications because of their metal‐chelating properties and their key role in bacterial growth and virulence. This review focuses on the biosynthesis of siderophores produced by fluorescent Pseudomonads, bacteria capable of colonizing a large variety of ecological niches. They are characterized by the production of chromopeptide siderophores, called pyoverdines, which give the typical green colour characteristic of fluorescent pseudomonad cultures. Secondary siderophores are also produced by these strains and can have highly diverse structures (such as pyochelins, pseudomonine, yersiniabactin, corrugatin, achromobactin and quinolobactin).
Digital harm and addiction: An anthropological view
Authors: SUTTON THEODORA
Published: February 2020

A broad trend of anti‐tech rhetoric has raised fears about the dangers of digital overuse and reliance and suggests that technology is addictive, unnatural or harmful. Some people have limited their hours of ‘screen time’ or resorted to the practice of ‘digital detoxing’ – a catch‐all term to describe temporarily ‘leaving’ the digital world. Using her ethnographic work in a North American digital detox retreat, the author considers an anthropological approach to digital harm and addiction that emphasizes their socially constructed nature. Following Horst and Miller (2012) and the view that digital harms are socially constructed, she argues that digital technology will be removed in different places for different reasons, and that geographically bound cultural values are vital to understanding how digital harms come to be imagined and counteracted. Whether or not digital use will ever be proven to be clinically harmful, digital harm is best viewed as a ‘social fact’.

Objective

To establish the age‐specific centiles of serum anti‐müllerian hormone (AMH) levels in Chinese women, and to explore the use of multiples of median (MoM) AMH levels for the diagnosis of polycystic ovary syndrome (PCOS).

Design

An observational study.

Setting

University‐affiliated hospitals and community clinics.

Population

We included 3137 healthy women aged 20–44 years recruited prospectively or who had archived serum samples from previous research projects. Another validation cohort of 751 women with PCOS as well as ovulatory controls, which was a convenient sample of women attending for infertility or menstrual disorders, was also studied.

Methods

The serum samples were assayed for AMH by the automated Access AMH assay.

Main outcome measures

Age‐specific reference ranges were constructed on the primary cohort with the Lambda‐Mu‐Sigma method. The MoM AMH of each subject in the validation cohort was calculated.

Results

Centile curves of serum AMH level against age were established. MoM AMH was significantly higher in women with PCOS than in controls (P < 0.05). The area under the ROC curve was 0.852 (95% confidence interval [CI] 0.825–0.877) (P < 0.0001) for discriminating women with PCOS from ovulatory controls by MoM AMH.

Conclusions

We established a set of year‐by‐year age‐specific reference ranges of serum AMH levels in Chinese women. The MoM AMH derived from this set of reference ranges is a promising tool to replace antral follicle count in the diagnosis of PCOS.

Tweetable abstract

A set of age‐specific reference ranges of AMH levels was established in Chinese women. Multiples of median AMH may be used to diagnose PCOS.
Detection of Inflicted Bruises by Alternate Light: Results of a Randomized Controlled Trial

Published: February 2020

Bruises are often difficult to detect on victims of violence, potentially impacting investigation and prosecution. The purpose of our randomized controlled trial was to measure the effectiveness of an alternate light source (ALS) within visible and long ultraviolet spectrums at improving bruise detection compared to white light over time. We also examined the effects of skin color, age, gender, localized fat, and injury mechanism on bruise detection. Participants included 157 healthy adults with balanced sampling across six skin color categories. Bruises were created under the controlled application of a paintball pellet and dropped weight to one upper and lower arm, respectively. Using a crossover design, both bruises were examined 21 times over 4 weeks. Ten different wavelength (350–535 nm) and filter (yellow, orange, red) combinations were used. Multilevel models were used to analyze 2903 examinations on both upper and lower arms. Results in multivariable models showed after controlling for other covariates 415 and 450 nm using a yellow filter had greater odds of detecting evidence of bruising than white light (Upper Arm: 415 nm: OR = 5.34, 95% CI: 4.35–6.56; 450 nm: OR = 4.08, 95% CI: 3.36–4.96). Under either light source, being female and having more localized fat had increased odds of detecting bruises created by the dropped weight (female: OR = 2.96, 95% CI: 2.37–3.70; fat: OR = 1.21, 95% CI: 1.09–1.34). Our results support ALS as an appropriate tool to enhance concurrent physical assessment of bruises in the presence of known history of injury. Future development and evaluation of clinical practice guidelines for ALS application are needed.
