Recognition and labeling of faults in wind turbines with a density-based clustering algorithm
Authors: Luo Shuai , Liu Hongwei , Qi Ershi
Published: June 2021

Purpose

The purpose of this paper is to recognize and label the faults in wind turbines with a new density-based clustering algorithm, named contour density scanning clustering (CDSC) algorithm.

Design/methodology/approach

The algorithm includes four components: (1) computation of neighborhood density, (2) selection of core and noise data, (3) scanning core data and (4) updating clusters. The proposed algorithm considers the relationship between neighborhood data points according to a contour density scanning strategy.

Findings

The first experiment is conducted with artificial data to validate that the proposed CDSC algorithm is suitable for handling data points with arbitrary shapes. The second experiment with industrial gearbox vibration data is carried out to demonstrate that the time complexity and accuracy of the proposed CDSC algorithm in comparison with other conventional clustering algorithms, including k-means, density-based spatial clustering of applications with noise, density peaking clustering, neighborhood grid clustering, support vector clustering, random forest, core fusion-based density peak clustering, AdaBoost and extreme gradient boosting. The third experiment is conducted with an industrial bearing vibration data set to highlight that the CDSC algorithm can automatically track the emerging fault patterns of bearing in wind turbines over time.

Originality/value

Data points with different densities are clustered using three strategies: direct density reachability, density reachability and density connectivity. A contours density scanning strategy is proposed to determine whether the data points with the same density belong to one cluster. The proposed CDSC algorithm achieves automatically clustering, which means that the trends of the fault pattern could be tracked.

Authors: Waheed Abdul , Zhang Qingyu , Zafar Abaid Ullah , Zameer Hashim , Ashfaq Muhammad , Nusrat Anam
Published: June 2021

Purpose

This study investigates the impact of corporate social responsibility (CSR) on organizational performance, especially competitive performance (CP) along with moderating role of the organizational culture (OC) from the banking sector of China. Drawing on the stakeholder theory, the first goal is to examine the relationships between CSR and organizational CP. Second, the purpose is to evaluate the moderation of OC between the relationship of CSR and CP, respectively.

Design/methodology/approach

SEM using SmartPLS was majorly engaged to ascertain the relationship and to inquire the assumed hypotheses. The convenience sampling was engaged to collect the data from the Chinese banking market with the help of students, colleagues and personal visits.

Findings

The findings exhibited that CSR both external and internal CSR has significant correlations on organizational CP within banking sector of China. Second, the findings revealed a positive moderation influence of OC between the relationships of CSR and organizational CP. The comprehensive analysis of each factor of CSR on organizational CP was autonomously inspected to understand the insights which ensure that how the incorporation of CSR and OC activities may improve organizational CP.

Research limitations/implications

This study faces numerous limitations related to sample and geographic locations that assure new work possibilities for researchers across the world.

Practical implications

This study equips insightful information for management on how organizations can obtain CP by consolidating CSR and OC activities as their more productive strategic tools. This article endows with potential theoretical and managerial implications with empirical addition to concerned literature of OC, CSR and organizational CP.

Social implications

Understanding OC and CSR activities can provide interesting and helpful insights for the personnel to perform well within the banking institutes.

Originality/value

The topic of CSR and culture has been known as the evolving concept that is getting strong concern for the researchers. The additional work particularly empirical is yet required to explore the insights on CSR and OC themes worldwide, especially in developing nations.
Fabric defect detection based on multi-source feature fusion
Authors: Liu Zhoufeng , Liu Shanliang , Li Chunlei , Li Bicao
Published: June 2021

Purpose

This paper aims to propose a new method to solve the two problems in fabric defect detection. Current state-of-the-art industrial products defect detectors are deep learning-based, which incurs some additional problems: (1) The model is difficult to train due to too few fabric datasets for the difficulty of collecting pictures; (2) The detection accuracy of existing methods is insufficient to implement in the industrial field. This study intends to propose a new method which can be applied to fabric defect detection in the industrial field.

Design/methodology/approach

To cope with exist fabric defect detection problems, the article proposes a novel fabric defect detection method based on multi-source feature fusion. In the training process, both layer features and source model information are fused to enhance robustness and accuracy. Additionally, a novel training model called multi-source feature fusion (MSFF) is proposed to tackle the limited samples and demand to obtain fleet and precise quantification automatically.

Findings

The paper provides a novel fabric defect detection method, experimental results demonstrate that the proposed method achieves an AP of 93.9 and 98.8% when applied to the TILDA(a public dataset) and ZYFD datasets (a real-shot dataset), respectively, and outperforms 5.9% than fine-tuned SSD (single shot multi-box detector).

Research limitations/implications

Our proposed algorithm can provide a promising tool for fabric defect detection.

Practical implications

The paper includes implications for the development of a powerful brand image, the development of “brand ambassadors” and for managing the balance between stability and change.

Social implications

This work provides technical support for real-time detection on industrial sites, advances the process of intelligent manual detection of fabric defects and provides a technical reference for object detection on other industrial

Originality/value

Therefore, our proposed algorithm can provide a promising tool for fabric defect detection.
Dynamic drape behaviours of wool woven suiting fabrics considering real-time use
Authors: Balci Kilic Gonca , Demir Murat , Kilic Musa
Published: June 2021

Purpose

The purpose of this paper is to analyse dynamic drape behaviours of 100% wool woven suiting fabrics considering real-time usage.

Design/methodology/approach

Dynamic drape coefficients of 100% wool woven fabrics were measured at different rotation speeds (25, 75, 125 and 175 rpm) with a commercially used fabric drape tester which works on image processing principle. Average daily walking speed of male and female volunteers was determined and the closest rotation speed was selected to calculate dynamic drape coefficient at walking (DDCw). Besides, bending rigidity and shear deformation properties, which are known to be related to the static drape behaviours of the fabrics, were also measured and the relationships between these parameters and DDCw were examined.

Findings

As a result of the experimental study, it was found that dynamic drape coefficients become greater, which means the fabrics take flatter position, with the increase of the rotation speed. In addition, it was also seen that parameters known to be related to static drape behaviours such as unit weight and bending stiffness have less effect on the dynamic drapes of fabrics. For the estimation of dynamic drape behaviour of fabrics, parameters such as static perimeter, dynamic perimeter, etc. are found more significant.

Originality/value

To date, although studies about dynamic drape behaviours of the fabrics claimed that dynamic drape gives more realistic results for in wearer experience, few of them focused on the rotation speed of dynamic drape tester for real-time usage. As dynamic drape behaviours of fabrics may differ for different rotation speed, determining appropriate speed in accordance with real-time usage gives more realistic results.
Do they practice what they preach? The presence of problematic citations in business ethics research
Authors: Serenko Alexander , Dumay John , Hsiao Pei-Chi Kelly , Choo Chun Wei
Published: June 2021

Purpose

In scholarly publications, citations play an essential epistemic role in creating and disseminating knowledge. Conversely, the use of problematic citations impedes the growth of knowledge, contaminates the knowledge base and disserves science. This study investigates the presence of problematic citations in the works of business ethics scholars.

Design/methodology/approach

The authors investigated two types of problematic citations: inaccurate citations and plagiarized citations. For this, 1,200 randomly selected citations from three leading business ethics journals were assessed based on: (1) referenced journal errors, (2) article title errors and (3) author name errors. Other papers that replicated the same title errors were identified.

Findings

Of the citations in the examined business ethics journals, 21.42% have at least one error. Of particular concern are the citation errors in article titles, where 3.75% of examined citations have minor errors and another 3.75% display major errors – 7.5% in total. Two-thirds of minor and major title errors were repeatedly replicated in previous and ensuing publications, which confirms the presence of citation plagiarism. An average article published in a business ethics journal contains at least three plagiarized citations. Even though business ethics fares well compared to other disciplines, a situation where every fifth citation is problematic is unacceptable.

Practical implications

Business ethics scholars are not immune to the use of problematic citations, and it is unlikely that attempting to improve researchers' awareness of the unethicality of this behavior will bring a desirable outcome.

Originality/value

Identifying that problematic citations exist in the business ethics literature is novel because it is expected that these researchers would not condone this practice.
IFRS adoption and firms’ opacity around the world: what factors affect this relationship?
Authors: Mongrut Samuel , Tello Marín Manuel , Torres Postigo Maria del Carmen , Fuenzalida O’Shee Darcy
Published: June 2021

Purpose

This paper aims to identify what are the moderating factors affecting the relationship between firms’ adoption of international financial and reporting standards (IFRS) and the firm’s opacity.

Design/methodology/approach

This study uses the meta-analysis methodology from Hunter et al. (1982) to find if the mere IFRS adoption reduces firm’s opacity and a meta-regression from Stanley and Jarrell (1989) to identify the moderating factors that may influence this relationship.

Findings

Contrary to previous studies, this study finds a low, negative and nonsignificant correlation between IFRS adoption and firms’ opacity, but this relationship depends on the geographical region. Using 34 results from 28 studies from different continents published between 2005 and 2018 this study finds that IFRS adoption reduces opacity in countries with common law (COML) and with more authorities’ oversight and power to enforce the rules.

Originality/value

This study finds two institutional commonalities between different previous studies that intend to assess the impact of the IFRS adoption upon firms’ opacity: the legal system and the authorities’ oversight power.
SME managers' learning from crisis and effectual behaviour
Authors: Haneberg Dag Håkon
Published: June 2021

Purpose

The COVID-19 pandemic has entailed a critical situation for small- and medium-sized enterprises (SMEs) since restrictions on business activity have been imposed by authorities to reduce infections. The result is that SME managers must manage their firms through a crisis under very challenging conditions. The purpose of the present paper is to address how SME managers respond in the second “wave” of COVID-19 based on their perceived uncertainty as well as eventual learning from the first “wave” in early 2020.

Design/methodology/approach

Four hypotheses are presented, resulting in a theoretical model relating crisis impact, uncertainty, learning from crisis experience and effectuation behaviour. The theoretical model is tested through an empirical questionnaire-based quantitative study of Norwegian SMEs in the bar and restaurant sector, applying structural equation modelling as the analytical technique.

Findings

The results show that impact from COVID-19 leads to both uncertainty and learning and further that uncertainty primarily leads to a focus on affordable loss while learning leads to experimentation behaviour.

Originality/value

The present paper is novel in several ways. First, it empirically studies a unique situation where a crisis encompasses two “waves” of significant impact on the firms in focus. This provides the opportunity to address managers' learning through a crisis for application in a very similar situation later. Second, the present paper provides an empirically supported model of how uncertainty or learning leads to different dimensions of effectuation behaviour in a crisis situation.
Enhancing entrepreneurial learning through mentoring: a situational and generic mentor role taxonomy
Authors: Kubberød Elin , Ladegård Gro
Published: June 2021

Purpose

The experiences materialising as learning tasks in the entrepreneurial context do not automatically transform into effective learning for a novice entrepreneur. In this paper, we develop a comprehensive and situational role taxonomy for entrepreneurial mentoring meant to address this challenge.

Design/methodology/approach

Entrepreneurial mentoring builds on the assumption that it can facilitate the transformation of experience and consequently enhance the learning outcomes for a novice entrepreneur. By integrating and extending the extant research on entrepreneurial learning and mentoring, we argue for a dynamic and situational approach, scrutinising the fit between discrete entrepreneurial learning modes and the mentoring functions targeting them.

Findings

We complete our theorising by developing four propositions and a taxonomy of mentor roles. The role taxonomy comprises a repertoire of four different roles that target the learning modes through learning-enabling mechanisms drawn from the learning literature.

Originality/value

The role taxonomy poses important implications for future entrepreneurship research. The role taxonomy can be directly employed in more targeted, formal training programmes for both mentees and mentors.
How do the current auditing standards fit the emergent use of blockchain?
Authors: Gauthier Marion Pauline , Brender Nathalie
Published: June 2021

Purpose

Blockchain is expected to impact reporting and auditing processes. Indeed, the increasing use of blockchain could affect the nature and extent of information available to auditors and how audits are performed. This paper aims to investigate how auditors are assessing the relevance of the current auditing standards in light of the emergent use of blockchain technology.

Design/methodology/approach

Based on qualitative content analysis, this paper analyzed semi-structured interviews with auditors to understand their shared perception of how the current auditing standards address blockchain’s emergence.

Findings

The findings reveal a growing demand for information technology (IT) auditing standards, as well as a mismatch in timing between the quickly changing IT environment and the regulators’ slowness in releasing new standards or updating standards.

Research limitations/implications

The findings reflect the external auditors’ points of view and cannot be generalized to all countries, but future studies should address the development of specific IT-related auditing standards to better fit the fast-evolving technology environment in ways that consider the other stakeholders’ points of view, including those of the standard setters.

Practical implications

The results of this study show that auditors consider the current auditing standards for IT to be too vague, and they need more guidance on both auditing blockchain and using technologies as audit tools.

Originality/value

The original contribution of this study lies in the in-depth understanding it provides of the adequacy of the current auditing standards to audit companies using blockchain, which is an under-researched topic.
Analyzing glacial lake outburst flood triggers for sustainable disaster risk mitigation: an interpretive structural modelling based approach
Authors: Trivedi Ashish , Chauhan Ankur , Singh Surya Prakash
Published: June 2021

Purpose

Climate change and global warming pose a serious threat to the community as deglaciating environments trigger glacial lake outburst floods (GLOFs). The Sendai framework underpins the role of disaster risk reduction (DRR) for sustainable development, thereby calling for the development of GLOF hazard and risk assessment procedures. This study aims to delineate the enablers of GLOF risk and establish a contextual relationship between them.

Design/methodology/approach

The risk enablers are identified from the extant GLOF literature, and the experts from disaster management area are consulted to explore the underlying contextual relationship among them. An interpretive structural model is developed from the responses to analyze the contextual relationships among the risk enablers.

Findings

The interpretive structural modeling results manifest that seismic activity, temperature and precipitation events, and proximity are key drivers that trigger flash floods from the lakes and an effective assessment of these triggers may contribute significantly to GLOF risk mitigation.

Originality/value

The study models the complex relationship among the risk enablers for a glacial flood hazard that find commonality across all geographic contexts. The findings provide the practitioners of DRR useful insights into these factors and their subsequent impact on others, while conducting hazard assessment of glacial lakes that may contribute to the sustainable development of settlements lying downstream to glacial lakes.
Openness to experience moderates psychological contract breach–job satisfaction tie-in
Authors: Opoku Mensah Abigail , Koomson Samuel
Published: June 2021

Purpose

This paper aims to assess the tie-in between psychological contract breach (PCB) and job satisfaction (JST) amongst medical doctors (MDs) working in two stress-prone regions of Ghana, and further analyses the moderating effect of openness to experience (OPE) on this tie-in.

Design/methodology/approach

Responses from 214 MDs were analysed. Questionnaires were self-administered. Research philosophy was positivism, research approach was quantitative, research design was explanatory and study design was cross-sectional. Test of normality, Kaiser-Meyer-Olkin measure of sampling adequacy and Bartlett’s test of sphericity were applied. Both reflective measurement and structural models were assessed. Path coefficients were analysed using partial least squares (PLS) algorithm tool and moderation effect was conducted using the product indicator approach. Control variables were sex (GEN1), age (GEN2), employment type (GEN3) and tenure (GEN1). A significant level was set at 5%. Smart PLS 2.0 M.3 software was used.

Findings

The analysts found support for a significant moderating effect of OPE on the tie between PCB and JST, such that the consequences of PCB on JST was minimised for MDs who scored high on OPE trait.

Practical implications

PCB, if not addressed, may lead MDs to be less satisfied with their jobs. In stress-prone health zones where PCB exists, MDs who are inspired, creative, self-sufficient, experimenting and visionary are more likely to be satisfied with their job.

Originality/value

This study offers health-care literature on the moderating role of OPE personality dimension on the bond between PCB and JST, using PLS-structural equations modelling, which is a superior and robust analytical tool.
Wind energy in the Gulf Cooperation Council region: progress, challenges and strategies for development
Authors: Connelly Colby , Xydis George
Published: June 2021

Purpose

Until recently, the Gulf Cooperation Council (GCC) region, whose members consist of Saudi Arabia, the United Arab Emirates, Kuwait, Qatar, Oman and Bahrain, has not significantly focused on the green transition. Specifically, wind energy development has made minimal progress relative to that of other regions.

Design/methodology/approach

The abundance of cheap fossil fuels in the region has not incentivized renewable energy development, and where this has taken place solar technologies are often preferred.

Findings

However, lower technology costs together with lost investment opportunities – also common elsewhere in the world, has increased the pressure on the GCC region from developers. This work qualitatively addresses the challenges and the strategies for the wind development in the area. It focuses on the analysis of different proposed type of investments – driven by a state-supported proposed fund – such as utility-scale investments, industry-specific investments, manufacturing investments and regional accelerators.

Originality/value

The work also suggests that Gulf sovereign wealth funds should act as the lead investors under new schemes, such as joint ventures, for wind development in the GCC, using their wealth to offering their populations with new sources of employment as well as energy that is sustainable.
Dispersal potential rather than risk assessment scores predict the spread rate of non‐native pines across New Zealand
Authors: Wyse Sarah V. , Hulme Philip E.
Published: June 2021

Pine (genus Pinus) species are planted extensively for forestry purposes in areas where they are non‐native, with the result that biological invasions by many of these species are of considerable concern in many regions. Owing to the economic importance of these species, management approaches must focus on reducing the risk that they will spread from plantings, which requires access to accurate and rigorous risk analysis protocols. However, while a variety of tools are available that accurately predict which species are likely to naturalise, their performance in forecasting the subsequent rates of spread of species once established remain unproven.

We compared 10 measures of risk that could be used to forecast the likelihood of pine spread, including established risk assessment tools as well as dispersal‐related plant traits: expert assessment of spreading vigour, the Z‐score, the Australian weed risk assessment protocol (WRA), seed terminal velocity, tree height, modelled dispersal potential, and planting effort. We examined the extent to which these measures were consistent in their estimate of risk and assessed their ability to accurately predict the spread rates of 10 non‐native naturalised pine species within New Zealand.

Of the measures of risk assessed here, only the models of dispersal potential were able to significantly predict the species' spread rates within New Zealand. In addition, seed terminal velocity was significantly correlated with expert assessment of the species spreading vigour, indicating these two measures capture similar aspects of risk. Modelled long‐distance dispersal from forests had the greatest explanatory power for the species spread rates in New Zealand.

Synthesis and applications. Common weed risk assessment tools and expert knowledge were unable to predict the spread rates of non‐native naturalised pine species in New Zealand, and should not be used to provide an index of spread risk. Instead, we recommend a move towards the use of dispersal models when assessing the spread risk of these species, even at national scales. Current practices relying on expert assessment are likely to underestimate the spread rate of species currently considered ‘low risk’, suggesting that these tools may be inadequate for predicting spread of these species.
Field boundary features can stabilise bee populations and the pollination of mass‐flowering crops in rotational systems

Published: June 2021

Pollinators experience large spatiotemporal fluctuations in resource availability when mass‐flowering crops are rotated with resource‐poor cereal crops. Yet, few studies have considered the effect this has on pollinator population stability, nor how this might be mitigated to maintain consistent crop pollination services.

We assess the potential of boundary features (standard narrow 1 m grassy margins, hedgerows and wide 4 m agri‐environment margins) to support and stabilise pollinator populations and pollination service in agricultural landscapes under crop rotation. Assuming a 6‐year rotation, we use a process‐based pollinator model to predict yearly pollinator population size and in‐crop visitation rates to oilseed rape and field bean across 117 study landscapes in England with varying amounts of boundary features. We model both ground‐nesting bumblebees and solitary bees and compare the predictions including and excluding boundary features from the landscapes.

Ground‐nesting bumblebee populations, whose longer‐lifetime colonies benefit from continuity of resources, were larger and more stable (relative to the no‐features scenario) in landscapes with more boundary features. Ground‐nesting solitary bee populations were also larger but not significantly more stable, except with the introduction of wide permanent agri‐environment margins, due to their shorter lifetimes and shorter foraging/dispersal ranges.

Crop visitation by ground‐nesting bumblebees was greater and more stable in landscapes with more boundary features, partly due to increased colony growth prior to crop flowering. Time averaged crop visitation by ground‐nesting solitary bees was slightly lower, due to females dividing their foraging time between boundary features and the crop. However, despite this, the minimum pollination service delivered was higher, due to the more stable delivery.

Synthesis and applications. Field boundary features have an important role in stabilising pollinator populations and pollination service in rotational systems, although maintenance of larger semi‐natural habitat patches may be more effective for stabilising less mobile solitary bee populations. We recommend using combinations of boundary features, accounting for pollinator range when spacing features/rotating crops, and synchronising boundary feature management with crop rotation to maximise their stabilising benefits.
Relationships between plant–soil feedbacks and functional traits
Authors: Xi Nianxun , Adler Peter B. , Chen Dongxia , Wu Hangyu , Catford Jane A. , van Bodegom Peter M. , Bahn Michael , Crawford Kerri M. , Chu Chengjin
Published: June 2021

Plant–soil feedbacks (PSF) and functional traits are two active but not well theoretically integrated areas of research. However, PSF and traits are both affected by life‐history evolution, so the two should theoretically be related.

We provide a conceptual framework to link plant functional traits to two types of PSF metrics, and hypothesize that individual PSF (plant performance in conspecific vs. heterospecific soil) should be related to the fast–slow trait spectrum, whereas pairwise PSF (the sum of the individual feedbacks for two species growing in each other's soils) should be related to trait dissimilarity. We performed meta‐analyses to test these hypotheses by compiling two datasets, one dataset consisting of individual PSF values and plant trait values (specific leaf area, SLA; leaf N concentration, LNC; specific root length, SRL; fine root diameter, FRD; plant height; seed mass), and the second consisting of pairwise PSF values and trait dissimilarity.

Our meta‐analyses showed that individual PSF values were more negative in faster‐growing species with greater SLA, LNC and SRL, supporting the growth–defence trade‐off hypothesis. Plant height was positively correlated with individual PSF, perhaps because large, long‐lived plants defend against pathogens better than smaller, shorter‐lived plants. We also found that larger‐seeded species had more positive or less negative PSF, likely reflecting greater tolerance of soil pathogens. The direction of relationships between trait dissimilarity and pairwise PSF varied with trait identity. Dissimilarities in SRL and FRD were negatively correlated with pairwise PSF while height dissimilarity was positively correlated with pairwise PSF. The contrasting relationships may reflect distinct links between trait dissimilarity and niche and fitness differences.

Synthesis. Our results demonstrate how an integration of PSF and trait‐based approaches can advance plant community ecology.
Writing to Barnett Newman: F. N. Souza and the End of Modernism
Authors: Nelson Saul
Published: June 2021

Beginning with an unsolicited letter to Barnett Newman written by the Indian modernist F. N. Souza, this essay seeks to reframe our understanding of the decline of modernism. Art‐historical consensus holds that, as the 1960s progressed, modernist art was swept aside by demands for political engagement to which it could not adapt. Souza's letter complicates this. On one hand, it criticizes Newman's latest paintings for expressing modernist values such as autonomy, transcendence, and universality, for amounting to the claim that ‘colour is ethics’. But on the other, rather than abandoning such concepts, as did most advanced art in the 1960s, Souza demands another, political modernism, one capable of grounding itself in reflection on the movement's historical complicity with colonialism and racism. This was a difficult project, and I reject the view that it was inherently progressive; indeed, I draw out the reactionary attitudes to which it could all‐too‐easily lead. Souza's desire, by 1969, to move beyond these without abandoning the historicity of modernism positions him closer to Newman than his letter suggests. Both proceeded, in ways that refuse the schematic alternatives of traditional art history, by making work that addressed political reality through the reflexive critique of modernism itself.
Epistemic in/justice in patient participation. A discourse analysis of the Dutch ME/CFS Health Council advisory process
Authors: de Boer Marjolein Lotte
Published: June 2021

In healthcare settings, patient participation is increasingly adopted as a possible remedy to ill people suffering from ‘epistemic injustices’ – that is to their unfair harming as knowers. In exploring and interpreting patient participation discourses within the 2013–2018 Dutch Myalgic Encephalomyelitis (ME)/Chronic Fatigue Syndrome (CFS) Health Council advisory process, this paper assesses the epistemological emancipatory value of this participatory practice. It reveals that in the analysed case, patient representatives predominantly offer biomedical knowledge about ME/CFS. They frame this condition as primarily somatic, and accordingly, perceive appropriate diagnostic criteria, research avenues and treatment options as quantifiable, objectifiable and explicitly non‐psychogenic. This paper argues that such a dominant biomedical patient participatory practice is ambiguous in terms of its ability to correct epistemic injustices towards ill people. Biomedicalized patient participation may enhance people's credibility and their ability to make sense of their illness, but it may also undermine their valid position within participatory practices as well as lead to (sustaining) biased and reductive ideas about who ill people are and what kind of knowledge they hold. The final section of this paper offers a brief reflection on how to navigate such biomedicalized participatory practices in order to attain more emancipatory ones.
Unravelling the ‘devolution paradox’: Citizen preferences for self‐rule and for shared rule
Authors: SCHAKEL ARJAN H. , SMITH RODNEY
Published: June 2021

Recent survey research has revealed a ‘devolution paradox’: some citizens who favour stronger regional governments inconsistently desire policy uniformity across regions and state‐wide intervention in policy provision. It is argued and empirically shown that preferences for regional authority can be broken down into preferences for self‐rule – that is, for autonomy for the region – and for shared rule – that is, for collaboration between regional and national governments. Drawing upon the International Constitutional Values Survey, which includes 4,930 respondents from 142 regions in eight countries, it is also shown that preferences for self‐rule and shared rule have different impacts. Preferences for self‐rule translate into a preference for regional reform that strengthens regional autonomy, whereas preferences for shared rule drive preferences for fiscal transfers from richer to poorer regions. These results are important because they can explain why citizens who are in favour of more regional authority may support an apparently ‘paradoxical’ set of policy outcomes.
Coronary (peri)‐arteritis in patients with IgG4‐related disease: A case series from the Central Anatolia Region of Turkey
Authors: Yardimci Gozde Kubra , Ardali Duzgun Selin , Bolek Ertugrul Cagri , Kilic Levent , Canpolat Ugur , Hazirolan Tuncay , Aytemir Kudret , Karadag Omer
Published: June 2021

Objective

Immunoglobulin G4‐related disease (IgG4‐RD) is a newly recognized fibro‐inflammatory disease which affects many systems, as well as the cardiovascular system. Identifying the coronary involvement like periaortitis, coronary periarteritis and pericarditis is important, as they often cause unfavorable outcomes.

Methods

Eighty‐one patients with IgG4‐RD were retrospectively evaluated for symptomatic coronary artery involvement from Hacettepe University Vasculitis Research Center (HUVAC) database. The demographic, laboratory, radiologic and clinical characteristics of the patients were assessed.

Results

Among 81 patients with IgG4‐RD, 6 patients (M/F:5/1) had coronary artery involvement. The patients’ median age was 57 and serum IgG4 levels were above normal except for one case. All patients with coronary arteritis revealed an increased coronary vessel wall thickening and stenotic lesions. The coronary aneurysm and pericarditis were observed in half of the patients. Immunosuppressive treatments were given to all the patients and most of them followed in stable condition.

Conclusion

Coronary arteritis is a rare but notable manifestation of IgG4‐RD. Although coronary periarteritis can cause significant morbidity and mortality, it seems better results can be achieved with early diagnosis and treatment.
Using qualitative data to classify reef fishes into dietary guilds
Authors: Howarth Odette R. , Liggins Libby , Smith Adam N. H.
Published: June 2021

Classification of species into dietary guilds that consume similar food resources can provide a useful framework for understanding ecosystem function. Traditionally, species were assigned to guilds qualitatively rather than quantitatively, largely due to a lack of detailed data on the diets of many species. More recently, detailed dietary data are collected and analysed quantitatively to produce a classification, but the collection of such data is intensive and usually limits a study to a small number of species. Here, we show that quantitative classifications can be built from qualitative data sourced from natural history texts and expert knowledge for well‐known fauna. We collected available data on the presence or absence of nine broad food item categories in the diets of 158 species of fish observed on New Zealand’s shallow rocky reefs. These data were analysed using multivariate statistical methods pioneered by K. R. Clarke and colleagues for use with site‐by‐species ecological survey data. In particular, we adapted a taxonomic dissimilarity measure to take into account a natural hierarchy of the food items, so that, for example, the diets of two species that consume different types of invertebrates were considered more similar to each other than those of, say, invertivores vs piscivores, or carnivores vs herbivores. Our analysis produced five distinct dietary guilds: Herbivore (9 species), Omnivore (11), Invertivore (80), Macro‐carnivore (52) and Piscivore (6). We suggest that invertivores, which made up around half of the species, are likely underrepresented in many studies due to the exclusion of smaller species. The approach of collecting broadly available qualitative data and applying modern multivariate quantitative methods to produce more inclusive dietary classifications may be usefully applied to other well‐known taxonomic groups for which detailed data are scarce.
The Political Intricacies of Common Space: A Rancièrian Approach to the “Public Land Grab”, London
Authors: Volont Louis , Dobson Tom
Published: June 2021

The concept of common space has seen revived attention in activist and academic circles. In a collective and non‐monetised manner, space‐commoners seek participatory control over the urban commonwealth. Lacking, however, within common space research is a deeper understanding of space‐commoning’s assumed politicality. Therefore, this article seeks to come to terms with the concept of politics and, subsequently, to highlight commoners’ possibilities and pitfalls on the road towards it. Mobilising Rancière’s lexicon of “police” and “politics”, the Public Land Grab is discussed. This case inverts the capitalist tool of the land grab in order to oppose capital‐led development and its intrinsic inequalities. We show how commoners subvert legislation (Localism Act) and functionalisation (of land). We firstly conclude that, when critical and tactical, an engagement with municipal institutions may enhance commoning’s political nature. We secondly conclude that political commoning entails a struggle that is quotidian and continuous rather than momentary and disruptive.

Published: June 2021

Discrepancies between registered prescriptions and patients' actual use of medications are described as frequent and often resulting in adverse medication events. We aimed to assess the extent of and causes behind discrepancies between medications listed in the Danish national prescription system (Shared Medication Record) and patients' actual use of medications. We prospectively reconciled medication for 260 consecutively admitted polypharmacy patients (>50 years and ≥5 prescriptions) at two hospitals in the Capital Region of Denmark. The type of discrepancies were determined and the cause of the discrepancies were evaluated as primarily caused by (1) the patient (i.e., intentional or unintentional non‐adherence) or (2) the health care system (i.e., lack of appropriate update of the SMR by physicians in primary or secondary care). There was a median of 12 [IQR 9–15] medications listed and 3 [IQR 1–5] medication discrepancies per patient (total n = 925). The majority (53%) of discrepancies were caused by the health care system, 32% were caused by the patients, of which 70% were intentional non‐adherence, and 15% had an indeterminable cause. In conclusion, discrepancies between medications listed in the Shared Medication Record and actual use of medications were frequent and were most often caused by clinicians not updating the prescription information.

Background

Clinical benefits of local antibiotics as an adjunct to nonsurgical treatment of peri‐implantitis have been widely reported, but most studies evaluated incipient peri‐implantitis lesions, and showed incomplete treatment success rates.

Purpose

To assess the clinical and microbiological outcomes of administering metronidazole in combination with minocycline as a local adjunct to the nonsurgical treatment of peri‐implantitis.

Materials and methods

One hundred and eighteen subjects with peri‐implantitis were recruited in a four‐center, three‐arm, and 12‐week randomized controlled trial. Subjects were randomly assigned to receive one of the following treatments: (a) MM—mechanical debridement + metronidazole‐minocycline ointment, (b) MC—mechanical debridement + minocycline ointment, (c) NST—mechanical debridement only.

Results

Except for four subjects who was excluded during the trial, a total of 114 patients with 114 implants (one implant per each patient) finally completed the trial and were included in the analyses. Multivariate logistic regression analysis revealed that the treatment success rates (absence of bleeding or suppuration on probing, and sites showing pocket probing depth [PPD] ≥5 mm) on at 12 weeks were higher in MM‐group patients (31.6%) and MC‐group patients (20.5%) compared to NST‐group patients (2.7%; p = 0.011 and 0.040, respectively). Subjects with deepest PPD ≥8 mm showed a significant difference in the PPD reduction between MM and MC groups at week 4 (p = 0.025) and week 12 (p = 0.047). Detection ratio of Tannerella forsythia was significantly lower for MM group than MC group (p = 0.038).

Conclusions

Additive use of either MM or MC results in significantly higher treatment success rates compared to sole mechanical debridement in nonsurgical treatment of peri‐implantitis. Moreover, MM contributes to a significantly greater reduction in the PPD compared to MC in deep pockets (cris.nih.go.kr KCT0004557).
The role of inorganic electrolyte (salt) in cellulosic fibre dyeing: Part 2 theories of how inorganic electrolyte promotes dye uptake
Authors: Burkinshaw Stephen M.
Published: June 2021

This review concerns the application of vat dyes, sulphur dyes, azoic colorants, direct dyes and reactive dyes to both natural and man‐made cellulosic fibres from aqueous dyebaths using exhaust dyeing processes and the role of added inorganic electrolyte in such dyeing processes. In this part of the paper, the various theories/hypotheses/concepts which have been proposed to account for the promotional effect exerted by added inorganic electrolyte on dye uptake are reviewed and scrutinised, from the viewpoints of the essential physico‐chemical properties of the five classes of dye used and the fundamental aspects of their application.
Assessment of the UV inkjet ink penetration into laboratory papers within triticale pulp and its influence on print quality

Today the print quality of digital printing techniques has improved and is considered satisfactory and competitive to analogue techniques for certain graphic products. Satisfactory print quality mostly depends on the interaction of ink and printing substrate where ink penetration has an important role. Namely, the ink penetration affects the parameters that describe the print quality together with visual appearance of print density and mottling. Therefore, it is important to select an adequate printing substrate for each printing technique. Awareness of environmental problems related to the shortage of wood raw materials has led to an increase in the use of recycled printing paper and in particular the implementation of new alternative sources of cellulose fibres instead of virgin wood fibres in the papermaking process. In this research the emphasis is precisely on defining the influence of ink penetration into laboratory papers made of triticale pulp on the final print quality. The laboratory printing papers were obtained by mixing triticale pulp with pulp from recycled fibres in three different portions. Papers were thereafter printed by ultraviolet (UV) inkjet printer and the ink penetration within laboratory papers with and without straw pulp was analysed using two methods of ink penetration analysis (microscopic/spectroscopic). The influence of ink penetration on the final print quality was observed and analysed based on several quality parameters (optical ink density, mottling and colorimetric values). These results confirmed that triticale pulp in laboratory papers provides equal print quality compared to laboratory papers made only from pulp from recycled fibres.

Purpose

To investigate the diagnostic accuracy of a different sample preparation protocol for fine needle aspiration cytology (FNAC) of thyroid nodules established during the COVID‐19 pandemic.

Methods

From April 2020, conventional smears during FNAC were ceased according to World Health Organization recommendations due to the increased infection risk for operators, and a new protocol using only liquid‐based cytology (LBC) was adopted. FNACs performed between April and July 2020 (COVID‐19 group) were retrospectively compared with those from December 2019 through March 2020 (Pre‐COVID‐19 group). The distribution of diagnoses based on SIAPEC‐IAP categories and the concordance between cytological and histological results were compared using the chi‐squared test.

Results

Categories based on FNAC for 90 and 82 thyroid nodules in the Pre‐COVID‐19 and COVID‐19 groups showed no significant difference in distribution (P = .081), with the following respective cases (and percentages): TIR1, 7 (8%) and 8 (10%); TIR1C, 0 (0%) and 6 (7%); TIR2, 59 (66%) and

55 (67%); TIR3A, 8 (9%) and 5 (6%); TIR3B, 1 (1%) and 2 (3%); TIR4, 5 (6%) and 1 (1%); and TIR5, 10 (12%) and 5 (7%). Among patients with potentially malignant lesions, surgery was performed for 12/16 (75%) nodules in the Pre‐COVID‐19 and 7/8 (88%) nodules in the COVID‐19 groups, with no significant differences between cytological and histological diagnoses (P = .931).

Conclusion

The new LBC‐only protocol provided similar diagnostic accuracy in comparison with conventional smears, and can be effectively applied during a viral pandemic improving operator safety.
