Health perception among the elderly in India: A gender perspective
Authors: Akhtar Saddaf Naaz , Saikia Nandita
Published: December 2021

There is an urgent need to understand and study the gender-based comprehensive own-perception approaches about health status. Our primary interest is to elucidate and capture whether and what determinants of gender disparity exist in own-perception about current and change in health status in Indian settings among the elderly. Therefore, we intended to examine the gender disparity in own-perception and their differences among the elderly in India. We used cross-sectional data from the 75th National Sample Survey Organizations (NSSO), collected from July 2017 to June 2018. The analytical sample constitutes 42759 cases of the elderly (eliminating two points of transgender). Thus, 21902 older men and 20857 older women have been considered. Two different measurements of own-perception about health status among the elderly have been used. We have calculated absolute gaps in the prevalence of current self-perception and change in health status by background characteristics. We carried out an ordered logistic regression model (or proportional odds model) to determine the predictors of health perception among the elderly. There is a clear gap between men and women in terms of rating poor perception about health; men generally have reported higher perception about their current health status when it comes to rating them excellent in terms of socio-economic outcomes like income, place of residence, and household structure. Despite numerous limitations, this study addressed the significant public health concern, which is crucial to address the challenge of the elderly health and their perception of well-being.

New goal-oriented requirements extraction framework for e-health services: a case study of diagnostic testing during the COVID-19 outbreak
Authors: Alotaibi Youseef , Subahi Ahmad F.
Published: December 2021

Purpose

This paper aims to introduce the goal-oriented requirements extraction approach (GOREA). It is an elicitation approach that uses, specifically, healthcare business goals to derive the requirements of e-health system to be developed.

Design/methodology/approach

GOREA consists of two major phases: (1) modelling e-health business requirements phase and (2) modelling e-health information technology (IT) and systems requirements phase. The modelling e-health business requirements phase is divided into two main stages: (1) model e-health business strategy stage and (2) model e-health business environment stage. The modelling e-health IT and systems requirements phase illustrates the process of obtaining requirements of e-health system from the organizational goals that are determined in the previous phase. It consists of four main steps that deal with business goals of e-health system: (1) modelling e-health business process (BP) step; (2) modelling e-health business goals step; (3) analysing e-health business goals step; and (4) eliciting e-health system requirements step. A case study based on the basic operations and services in hospital emergency unit for checking patient against COVID-19 virus and taking its diagnostic testing has been set and used to examine the validity of the proposed approach by achieving the conformance of the developed system to the business goals.

Findings

The results indicate that (1) the proposed GOREA has a positive influence on the system implementation according to e-health business expectations; and (2) it can successfully fulfil the need of e-health business in order to save the citizens life by checking them against COVID-19 virus.

Research limitations/implications

The proposed approach has some limitations. For example, it is only validated using one e-health business goal and thus it has to be authenticated with different e-health business goals in order to address different e-health problems.

Originality/value

Many e-health projects and innovations are not established based on robust system requirements engineering phase. In order to ensure the success delivery of e-health services, all characteristics of e-health systems and applications must be understood in terms of technological perspectives as well as the all system requirements.
Will contractors pursue unsustainable practices following environmental recovery? A highway case in China
Authors: Shang Ting , Hu Xin , Ye Kunhui , Tam Vivian W. Y.
Published: December 2021

Purpose

This study aims to map out contractors' thoughts on construction-related environmental recovery as an excuse for deliberately carrying on unsustainable construction.

Design/methodology/approach

A typical highway construction project in China was investigated. Textual materials were collected through semistructured interviews. Content analysis was conducted to derive qualitative data from the textual materials.

Findings

The research findings reveal a trend of environmental recovery associated with construction activities. It is found that contractors utilize this trend to maintain unsustainable construction. Furthermore, the effects of environmental recovery equip local governments with a tolerance for environmental degradation, and the environmental tolerance allows contractors to continue unsustainable construction without being discovered.

Originality/value

This paper presents an environmental recovery-based perspective on unsustainable construction and sheds some light on the promotion of sustainable construction.
Improvement of random forest by multiple imputation applied to tower crane accident prediction with missing data
Authors: Jiang Ling , Zhao Tingsheng , Feng Chuxuan , Zhang Wei
Published: December 2021

Purpose

This research is aimed at predicting tower crane accident phases with incomplete data.

Design/methodology/approach

The tower crane accidents are collected for prediction model training. Random forest (RF) is used to conduct prediction. When there are missing values in the new inputs, they should be filled in advance. Nevertheless, it is difficult to collect complete data on construction site. Thus, the authors use multiple imputation (MI) method to improve RF. Finally the prediction model is applied to a case study.

Findings

The results show that multiple imputation RF (MIRF) can effectively predict tower crane accident when the data are incomplete. This research provides the importance rank of tower crane safety factors. The critical factors should be focused on site, because the missing data affect the prediction results seriously. Also the value of critical factors influences the safety of tower crane.

Practical implication

This research promotes the application of machine learning methods for accident prediction in actual projects. According to the onsite data, the authors can predict the accident phase of tower crane. The results can be used for tower crane accident prevention.

Originality/value

Previous studies have seldom predicted tower crane accidents, especially the phase of accident. This research uses tower crane data collected on site to predict the phase of the tower crane accident. The incomplete data collection is considered in this research according to the actual situation.
She-E-Os and innovation: do female CEOs influence firm innovation?
Authors: Javaid Hafiz Mustansar , Ain Qurat Ul , Renzi Antonio
Published: December 2021

Purpose

This paper empirically investigates whether female CEOs (She-E-Os) have an effect on firm innovation among Chinese listed firms based on patent data. This study also delved further by looking at whether the internal corporate environment moderates the effect of female CEOs on innovation, that is, state ownership. Finally, this study investigates an additional test of financial constraints to examine whether financial constraints also moderate the impact of female CEOs on firm innovation.

Design/methodology/approach

This study used the data of all A-share listed companies on the Shanghai and Shenzhen stock exchanges for the period from 2008 to 2017. The authors use ordinary least squares regression as a baseline methodology, along with firm-fixed effect, lagged measure of female CEOs, alternative measures of innovation, Heckman two-step model and negative binomial regression to check and control the possible issue of endogeneity.

Findings

The authors’ findings show that CEO gender plays an important role in producing higher levels of innovation output by improving the governance structure. However, female CEOs have no effect on state-owned enterprises' (SOEs) innovation activities, which suggests that the main goal of SOEs is achieving sociopolitical objectives. Furthermore, female CEOs' influence on innovation output is weaker in firms with financial constraints.

Social implications

This study adds to the emerging global discussion on gender diversity. Many legislative bodies require a quota for women on corporate boards due to gender inequality. This study's findings reinforce such guidelines by emphasizing the economic benefits of including women in top management positions.

Originality/value

This study provides new insights by highlighting the role of female CEOs in increasing firms' innovation activities. Additionally, this study provides evidence on whether the internal corporate environment (state ownership and financial constraints) moderates female CEOs' effect on innovation.
Chinese entrepreneurs and workers at the crossroad: the role of social networks in ethnic industrial clusters in Italy
Authors: Biggeri Mario , Braito Lisa , Caloffi Annalisa , Zhou Huanhuai
Published: December 2021

Purpose

This paper aims to analyse the evolution of Chinese industrial ethnic clusters in Italy, by focusing on the role of social networks and the processes behind the phenomenon of Chinese worker exploitation and entrepreneur “self-exploitation”.

Design/methodology/approach

The case study is a sub-cluster of micro and small enterprises owned by Chinese entrepreneurs within the leather industrial district of Florence, Italy. This research adopts the following mixed methods: a small-scale survey to capture the characteristics of the sub-cluster and a social network analysis to describe cluster evolution, complemented by life-course interviews conducted with key informants and entrepreneurs.

Findings

Migrant social capital and social networks play a central role in the evolution of the case study sub-cluster. Social networks play a supportive role in migration, job creation, entrepreneurship formation and the creation of business opportunities. Simultaneously, they enhance the phenomenon of worker exploitation and entrepreneur self-exploitation. Furthermore, the more the business community grows, the more the economic performance of ethnic enterprises depends on agglomeration forces produced by the cluster.

Practical implications

The findings suggest a series of potential policies to upgrade the ethnic enterprises' capacities, to increase their formality and inclusion in the Italian social and economic systems and sub-cluster.

Originality/value

To the authors’ knowledge, this paper is the first attempt to examine the evolution of social networks in relation to the phenomenon of Chinese worker exploitation and entrepreneur self-exploitation in an ethnic industrial sub-cluster.
Management innovation: the influence of institutional pressures and the impact on competitive advantage
Authors: Alshumrani Salha , Baird Kevin , Munir Rahat
Published: December 2021

Purpose

Drawing on DiMaggio and Powell's (1983) perspective of institutional theory, this study examines the influence of institutional pressures on the adoption of management innovation and the subsequent impact of management innovation on competitive advantage.

Design/methodology/approach

Data were obtained from 156 middle-level managers in Australia using a survey questionnaire, with data analysed using structural equation modelling.

Findings

The results show that internal coercive pressures and normative pressures are positively associated with both dimensions of management innovation (i.e. practices and techniques). However, external coercive pressures were found to negatively influence management innovation techniques, and no association was found between mimetic pressures with either dimension of management innovation. Finally, both dimensions of management innovation were found to exhibit a positive influence on competitive advantage.

Originality/value

The findings provide organisations with an insight into the institutional factors that affect their ability to introduce new management practices and techniques (i.e. management innovation) and the role of management innovation in enhancing competitive advantage.
Digital entrepreneurship and emancipation: exploring the nexus in a conflict zone
Authors: Hassan Sharfa , Mir Ajaz Akbar , Khan Sher Jahan
Published: December 2021

Purpose

This paper aims to examine the emergence of digital entrepreneurship in a conflict environment to explore the emancipatory potential of digital technology in a rare context. The purpose of this paper is to take a micro-level investigation of digital entrepreneurs operating in a violent in-conflict area.

Design/methodology/approach

The analysis is based on multiple case studies from a violent conflict zone in India. This study used interview data from 10 digital entrepreneurs from the state of Jammu and Kashmir. Field data was collected with progressive rounds of interviews with the entrepreneurs, supplemented by published statistics and secondary data sources, and analysis was done with the help of qualitative data analysis software NVivo.

Findings

The context directed entrepreneurial behaviour and the motivation to start digital ventures. Entrepreneurs realized the potential of technology but its successful use was contingent upon their social positionalities. The digital entrepreneurial engagement of the entrepreneurs is classified into four dimensions: social digital entrepreneurship; business entrepreneurship; knowledge entrepreneurship; and institutional entrepreneurship.

Originality/value

The findings of the study contribute to the digital entrepreneurship literature by illustrating how a rare context influences venturing into technology sectors. The study advances the creative technology use, these in-conflict entrepreneurs with their existing resources maneuvered to create socially ingrained digital ventures. The study provides evidence to “conditional emancipation” attributable to digital entrepreneurship owing to the conflictual context in question.

The role of retailers during brand scandals: insights from a case study
Authors: Kapoor Sunaina , Banerjee Saikat , Signori Paola
Published: December 2021

Purpose

The role of retailers in influencing consumer attitude during a brand scandal is quite complex, as retailers are in direct contact with both marketers and consumers. The purpose of the exploratory research is to propose a theoretical model to capture the influences retailers exercise on consumers during brand scandals.

Design/methodology/approach

A qualitative approach has been adopted in the study. The study employs the grounded theory approach on the data collected by conducting in-depth interviews with 25 retailers.

Findings

Four contextual conditions and six behavioral antecedents of the retailer's role in the context of the brand scandal were identified. Then, the study finds that companies tend to follow two broad approaches during a brand scandal to address retailers' queries and apprehensions. On these bases, the study proposes a six-pronged typology to better understand retailers' role in shaping consumers' brand perception.

Originality/value

Existing literature has not paid adequate attention to this aspect of retailers' role in influencing consumer choices during brand scandal. To the best of the authors' knowledge, there is no prior research which investigates the role and influence of retailers in shaping consumer attitude during brand scandals. It is important to underline that the current research advocates retailers' significant role during a performance-based brand scandal. Specifically, the authors explored a health-related defective scandal of a well-known food brand. In addition, the study focuses on traditional grocery retailers, which already have special relationships with their consumers. Based on retailer perspectives, the authors' contribution is also updating the discussion of branding theory in case of scandals. The identified variables and constructs may be used for empirical investigation on the role of retailers in shaping consumer attitudes toward the scandalized brand.
Global vs local: analysis of the consumer-brand relationships in India
Authors: Sengupta Aniket , Wesley Scarlett , Cavender RayeCarol , Lee Min Young
Published: December 2021

Purpose

The purpose of this study is to analyze two global brands (i.e. Benetton and Tommy Hilfiger) and one Indian brand (i.e. Wills Lifestyle) in terms of general brand impression, brand specific associations and brand commitment. In addition, the study investigates how the regional differences in India and Indian consumers' affinity towards global brands influence the consumer-brand relationships.

Design/methodology/approach

The research framework has been developed based on consumer-brand relationship theory. The consumer–brand relationship is an important indicator of the success of brands, especially when brands attempt to expand to other markets (Roper and Parker, 2006; Bastos and Levy, 2012). Three brand types were chosen for this study. The choice of the US global brand is Tommy Hilfiger, the European global brand is United Colors of Benetton, and the Indian domestic brand is Wills Lifestyle. The study utilized a repeated measure (split-plot) design involving more than two independent groups. A split-plot analysis of variance analyses a design in which a repeated measure (i.e. within subjects) factor is crossed with a between-subjects (i.e. treatment variable) factor.

Findings

The results confirm the importance of global brands over local brands in the Indian apparel consumer market. This study also examined how Indian consumers' affinity for global brands influences their evaluation of the global brands and the local Indian brands.

Originality/value

The study expands the literature on Indian consumer brand preferences through the investigation of three brands. The theoretical background of the study is the consumer-brand relationship theory that explains the importance of consumer–brand relationship when brands attempt to expand to other markets.
COVID-19 and agri-food value chain: a systematic review and bibliometric mapping
Authors: Das Naba Kumar , Roy Arup
Published: December 2021

Purpose

The COVID-19 has had a diversified and dynamic impact on the food and agricultural sector, particularly in the agri-food value chain. Although a good number of articles were published in various countries and continents covering various aspects of the impact of COVID-19 on the agri-food value chain, no significant studies were found related to the mapping of published literature to know about the scenario and current trend research. The study aims to perform a systematic review and bibliographic mapping in the agri-food value chain to provide insights into the same.

Design/methodology/approach

Articles included in the Scopus database from January 1, 2020 to July 10, 2021 are considered. After initial screening and inclusion criteria, 41 articles have been selected to perform a systematic review which is published in the agri-food value chain. In addition to this, by considering the growth of the online food market, systematic mapping with the application of bibliometric analysis is performed to know the trend of the publications. Co-occurrence analysis with VOS viewer software version 1.6.16 is used for making network maps and supports the visualization of these maps.

Findings

The synthesis of the findings reveals that four broad themes recur in the articles: namely, food security and crisis during the pandemic, food price fluctuations, the impact of COVID-19 and disruption in the agri-food value chain and resilience strategies to strengthen the value chain. Alongside, the synthesis of the findings, this study describes the geographical coverage, methodologies used, sector/industry-specific context of the articles and scope of future research. In co-occurrence analysis with keywords, four clusters are identified related to the online food market and are categorized as “COVID-19 and Online food delivery services,” “Consumer satisfaction to online food delivery services,” “Food delivery system” and “Demographic impact on online food market.”

Research limitations/implications

The study considers only the article from the Scopus database and article published between January 1, 2020 and July 10, 2021. Future studies are encouraged related to impact analysis studies of resilient strategies suggested by various authors by considering multiple databases.

Originality/value

This study will be beneficial for scholars and policymakers to know what is trending in the agri-food value chain and policymakers can implement various resilience strategies as discussed to mitigate the impact. The future research scope highlighted in this paper will encourage scholars and academicians to explore this area and will provide in-depth understanding.
Family members as hybrid owner-managers in family-owned newspaper companies: handling multiple institutional logics
Authors: Boers Börje , Andersson Thomas
Published: December 2021

Purpose

This article aims to increase the understanding of the role of individual actors and arenas in dealing with multiple institutional logics in family firms.

Design/methodology/approach

This study follows a case-study approach of two family-owned newspaper companies. Based on interviews and secondary sources, the empirical material was analysed focussing on three institutional logics, that is, family logic, management logic and journalistic logic.

Findings

First, the authors show how and in which arenas competing logics are balanced in family-owned newspaper companies. Second, the authors highlight that family owners are central actors in the process of balancing different institutional logics. Further, they analyse how family members can become hybrid owner-managers, meaning that they have access to all institutional logics and become central actors in the balancing process.

Originality/value

The authors reveal how multiple institutional logics are balanced in family firms by including formal actors and arenas as additional lenses. Therefore, owning family members, especially hybrid owner-managers, are the best-suited individual actors to balance competing logics. Hybrid owner-managers are members of the owner families who are also skilled in one or several professions.
Broadening international mentoring: contexts and dynamics of expatriate and HCN intercultural mentoring
Authors: van Bakel Marian , Vaiman Vlad , Vance Charles M. , Haslberger Arno
Published: December 2021

Purpose

To enlarge the focus on international mentoring beyond traditional company-assigned expatriates, this conceptual paper examines important contexts and dynamics of intercultural mentoring involving traditional expatriates and host country nationals (HCNs), with both as mentors and mentees.

Design/methodology/approach

This conceptual paper explores how intercultural mentoring in different contexts can guide the individual professional development of expatriates and HCNs, and in doing so, contributes to MNC knowledge management and organization development.

Findings

Major contributions of this paper include increased attention to the role of culture in mentoring, and an illumination of important intercultural mentoring opportunities and imperatives involving traditional company-assigned expatriates and HCNs, who are key global talent players in MNC knowledge management and overall operations performance. This paper also provides practical recommendations on how organizations can facilitate mentoring within a global context, as well as suggestions for viable avenues for future research, including further extending the global talent reach of international mentoring.

Originality/value

This paper emphasizes the importance of taking the intercultural context into account when planning and managing mentoring in MNCs and outlines how culture can affect mentoring relationships involving traditional company-assigned expatriates and HCNs. This contextual aspect has often been neglected in the extant literature, yet can be crucial for the success of mentoring relationships that cross cultural borders. With its inclusion of HCNs, this paper also expands the picture of international mentoring beyond the traditional focus on company-assigned expatriates.
The potential of virtual global mobility: implications for practice and future research
Authors: Selmer Jan , Dickmann Michael , Froese Fabian J. , Lauring Jakob , Reiche B. Sebastian , Shaffer Margaret
Published: December 2021

Purpose

The COVID-19 pandemic has forced global organizations to adopt technology-driven virtual solutions involving faster, less costly and more effective ways to work worldwide even after the pandemic. One potential outcome may be through virtual global mobility (VGM), defined as the replacement of personal physical international interactions for work purposes with electronic personal online interactions. The purpose of this article is to establish VGM as a theoretical concept and explore to what extent it can replace or complement physical global work assignments.

Design/methodology/approach

This perspectives article first explores advantages and disadvantages of global virtual work and then discusses the implementation of VGM and analyses to what extent and how VGM can replace and complement physical global mobility.

Findings

Representing a change of trend, long-term corporate expatriates could become necessary core players in VGM activities while the increase of the number of global travelers may be halted or reversed. VGM activities will grow and further develop due to a continued rapid development of communication and coordination technologies. Consequently, VGM is here to stay!

Originality/value

The authors have witnessed a massive trend of increasing physical global mobility where individuals have crossed international borders to conduct work. The authors are now observing the emergence of a counter-trend: instead of moving people to their work the authors often see organizations moving work to people. This article has explored some of the advantages, disadvantages, facilitators and barriers of such global virtual work. Given the various purposes of global work the authors chart the suitability of VGM to fulfill these organizational objectives.
A qualitative study of hospital clinical staff perceptions of their interactions with healthcare middle managers
Authors: Kendrick Madeleine , Kendrick Kevin B. , Taylor Nicholas F. , Leggat Sandra G.
Published: December 2021

Purpose

The authors explored clinical staff perceptions of their interactions with middle management and their experiences of the uncongeniality of their working environment.

Design/methodology/approach

Semi-structured interviews of clinical staff from an Australian public health service's Emergency, Surgery and Psychiatry departments. Volunteer interview transcripts were inductively coded using a reflexive thematic content analysis.

Findings

Of 73 interviews, 66 participants discussed their interactions with management. Most clinicians considered their interactions with middle management to be negative based on a violation of their expectations of support in the workplace. Collectively, these interactions formed the basis of clinical staff perceptions of management's lack of capacity and fit for the needs of staff to perform their roles.

Practical implications

Strategies to improve management's fit with clinicians' needs may be beneficial for reducing uncongenial workplaces for healthcare staff and enhanced patient care.

Originality/value

This article is among the few papers that discuss interactions with management from the perspective of clinical staff in healthcare. How these perspectives inform the perception of workplace uncongeniality for clinicians contributes greater understanding of the factors contributing to adversarial relationships between clinicians and managers.
Influence of stakeholders' perception on value creation and measurement: the case of football clubs
Authors: Perechuda Igor , Čater Tomaž
Published: December 2021

Purpose

The presented study aims to identify and classify the value factors that influence the value of football clubs from the stakeholder perspective, while also discussing how these factors can affect the choice of valuation methods. The paper considers how value should be measured from the perspective of stakeholders. Research focuses on clubs embedded deeply in a wide interrelated network of stakeholders.

Design/methodology/approach

A mixed research approach was established in order to obtain a more holistic understanding of value creation, value factors and measurement. The research builds on observational study with a mix of retrospective longitudinal study of Polish men's football clubs and interviews with stakeholders, which are then triangulated as part of a critical discussion on valuation methods.

Findings

The results show the most significant value factors determined by the stakeholders. The study discusses which performance and value measures should be used to measure value for the stakeholders of football clubs. Intellectual capital methods and asset-based methods should definitely be relied on as part of measuring the performance of football clubs within the stakeholders' network. All findings suggest the use of the multivariate valuation method in accordance with previous research.

Originality/value

The classified key value factors enable the management of football clubs to properly manage stakeholder relationships and address various stakeholders' concerns in a sustainable way. The paper proposes a research process, which may also be implemented in other studies in the non-profit sector and contributes to the literature in the fields of sports management.
Short‐selling pressure and year‐over‐year MD&A modifications
Authors: Maharjan Johan , Lee Seung Won
Published: December 2021

Using the SEC's Regulation SHO as a natural experiment, we examine the effect of an increase in short selling pressure on the year‐over‐year modification of management discussion and analysis (MD&A) section of firms' 10‐K reports. We find that the elevated threat of short selling, resulting from the removal of short‐sale constraint, causes the randomly selected pilot firms to modify the MD&A section less relative to the previous year than non‐pilot firms during the Regulation SHO period (2005–2007). Moreover, cross‐sectional analyses indicate that this effect is pronounced in firms with moderately good news; firms that increase investment or equity issuance; larger or overvalued firms; and firms with conservative managers, financial stability, and opaque information environments.
Fears and freedoms: A qualitative analysis of older adults’ basic psychological needs for autonomy, competence, relatedness and beneficence
Authors: Dendle Kelli , Buys Laurie , Vine Desley , Washington Tracy
Published: December 2021

Objectives

Self‐determination theory posits three universal psychological needs: autonomy, competence and relatedness. Beneficence has recently been proposed as an important behaviour for improved well‐being and eudaimonia. This study sought to qualitatively examine older adults’ experiences of basic psychological needs satisfaction and frustration.

Methods

Three separate and simultaneous national online focus groups were undertaken over four consecutive days. Older Australians (n =103) explored home and community life. Themes were identified using reflexive thematic analysis.

Results

Older adults are challenged in satisfying their psychological needs, especially around the time ‐ and after‐ they retire and as mobility decreases. Beneficence emerged as important for well‐being, congruent with evidence that beneficence influences well‐being beyond basic psychological need fulfilment.

Conclusions

Satisfactions and frustration may manifest differently for older adults than for other groups. Thus, their experiences may not adequately be captured by self‐report measures. Novel themes of ‘fears and freedoms’ were identified in the study. Fear pertained to the loss of autonomy and the freedom to spend time as one wishes.
Rituximab‐induced mild encephalopathy with a reversible splenial lesion syndrome (MERS): An adverse effect to add to the list
Authors: Thabet Maissa , Atig Amira , Fathallah Neila , Guiga Ahmed , Ben Yahia Wissal , Ouni Bouraoui , Ghannouchi Neirouz
Published: December 2021

Mild encephalopathy with a reversible splenial lesion syndrome (MERS) is a rare clinico‐radiological entity. Rituximab (RTX)‐induced MERS has never been described before. Herein, we report the case of a 33‐year‐old patient diagnosed since 2017, with an IgG4‐related disease (IgG4‐RD). This diagnosis was retained in the face of a prolonged fever, sicca syndrome, hepatic damage and renal pseudotumour associated to a high level of IGg4 at 2.8 g/L with suggestive renal histology. The patient was treated with corticosteroid therapy with persistence of renal impairment and nephrotic syndrome indicating RTX therapy. The patient received his first dose of RTX and presented neurological and respiratory impairments a few hours afterwards. An infectious investigation comprising a SARS CoV‐2 PCR and viral PCRs (VZV, herpes and CMV) on cerebrospinal fluid (CSF) were negative. The HBV, HCV, HIV, Parvo B19, CMV, EBV, herpes, mycoplasma and syphilis serologies as well as Legionella antigenuria were also negative. The patient had received intravenous immunoglobulins (IVIG) and methylprednisone, associated with sodium valproate with favourable outcome. The diagnosis of MERS induced by RTX was retained in our patient according to clinical and radiological features. We herein report the first case of MERS following RTX in a patient treated for IgG4‐RD.
How do humans group non‐rigid objects in multiple object tracking?: Evidence from grouping by self‐rotation
Authors: Hu Luming , Zhao Chen , Wei Liuqing , Talhelm Thomas , Wang Chundi , Zhang Xuemin
Published: December 2021

Previous studies on perceptual grouping found that people can use spatiotemporal and featural information to group spatially separated rigid objects into a unit while tracking moving objects. However, few studies have tested the role of objects’ self‐motion information in perceptual grouping, although it is of great significance to the motion perception in the three‐dimensional space. In natural environments, objects always move in translation and rotation at the same time. The self‐rotation of the objects seriously destroys objects’ rigidity and topology, creates conflicting movement signals and results in crowding effects. Thus, this study sought to examine the specific role played by self‐rotation information on grouping spatially separated non‐rigid objects through a modified multiple object tracking (MOT) paradigm with self‐rotating objects. Experiment 1 found that people could use self‐rotation information to group spatially separated non‐rigid objects, even though this information was deleterious for attentive tracking and irrelevant to the task requirements, and people seemed to use it strategically rather than automatically. Experiment 2 provided stronger evidence that this grouping advantage did come from the self‐rotation per se rather than surface‐level cues arising from self‐rotation (e.g. similar 2D motion signals and common shapes). Experiment 3 changed the stimuli to more natural 3D cubes to strengthen the impression of self‐rotation and again found that self‐rotation improved grouping. Finally, Experiment 4 demonstrated that grouping by self‐rotation and grouping by changing shape were statistically comparable but additive, suggesting that they were two different sources of the object information. Thus, grouping by self‐rotation mainly benefited from the perceptual differences in motion flow fields rather than in deformation. Overall, this study is the first attempt to identify self‐motion as a new feature that people can use to group objects in dynamic scenes and shed light on debates about what entities/units we group and what kinds of information about a target we process while tracking objects.
Lateglacial and Holocene sedimentary dynamics in northwestern Baffin Bay as recorded in sediment cores from Cape Norton Shaw Inlet (Nunavut, Canada)
Authors: Stevenard Nathan , Montero‐Serrano Jean‐Carlos , Eynaud Frédérique , St‐Onge Guillaume , Zaragosi Sébastien , Copland Luke
Published: December 2021

The physical, sedimentological, mineralogical and elemental geochemical properties of sediment cores AMD1803‐02BC and 01PC from the Cape Norton Shaw Inlet were investigated to reconstruct glacial sediment discharges from southeastern Manson Icefield and document the impact of ice–ocean interactions on the sediment dynamics and opening of the North Water Polynya (NOW) in northwestern Baffin Bay since the last deglaciation. Laminated glaciomarine sediments rich in quartz and feldspar are observed prior to 11 cal. ka BP and were probably deposited by hyperpycnal currents triggered by the local retreat of the southern margin of the Innuitian Ice. Detrital proxies suggest that Early Holocene sediment dynamics were mainly influenced by sea ice and iceberg rafting and meltwater discharges related to the deglaciation of eastern Smith (~11 to 10.65 cal. ka BP) and Jones (~10.7 cal. ka BP) sounds. This also provides an upper limit to the timing of formation of the NOW. The high detrital carbonate contents during 8.8 to 6.6 cal. ka BP confirm that enhanced carbonate‐rich sediment export from Nares Strait to northern Baffin Bay occurred during and after the deglaciation of Kennedy Channel (8.8 to 8.2 cal. ka BP). Canadian Shield sediment inputs have dominated since 6.6 cal. ka BP, indicating that sedimentation is mainly influenced by Cape Norton Shaw glacier discharges. The lower level of sedimentation recorded in core 01PC during the Middle to Late Holocene suggests an accelerated landward retreat of the Cape Norton Shaw glaciers in response to warmer marine conditions. During the Neoglacial period, higher sedimentation rates and detrital proxies in the cores suggest increased glacial erosional processes, probably associated with the long‐term declines in boreal summer insolation and glacier growth. Finally, mineralogical and grain‐size data in core 02BC support the idea that increased Arctic atmospheric temperatures have had an important influence on the glacial dynamics during the industrial period.
Place‐based civic science—collective environmental action and solidarity for eco‐resilience

Background

Educating children and young people (CYP) from marginalized communities about environmental crises poses a unique dilemma as educators strive to prepare them to deal with the climate crisis without compounding the stressors and fear of an unlivable future many already face. We explored how place‐based civic science (PBCS) can provide opportunities to engage youth in environmental understanding and action through teamwork in which youth feel that they belong to a group larger than themselves and gain a sense of hope from working with others toward shared goals. We argue that combining PCBS pedagogies of collective action and collaborative learning spaces can help to buffer against distress as CYP grapple with global environmental crises.

Methods

We drew from qualitative responses (student reflections and public presentations) of 486 6–12th graders (majority students of color) on what they learned from participating in PBCS projects. Projects involved egalitarian partnerships between adults from environmental organizations, teachers and student teams studying and acting together to mitigate problems and presenting their efforts in public venues.

Results

Students’ qualitative responses revealed an identification with their team and its goal forged through the work, respect for their voice, belief in their capacity and confidence to take collective action and even enjoyment of working together to address community concerns.

Conclusions

PBCS through collective learning/action in student teams and nonhierarchical intergenerational partnerships, and connections that CYP forge with organizations in the broader community, can help to build CYP’s agency and efficacy while addressing “emotionally heavy” issues such as climate change.

Background

The Japanese baseline series (JBS), established in 1994, was updated in 2008 and 2015. The JBS 2015 is a modification of the thin‐layer rapid‐use epicutaneous (TRUE) test (SmartPractice Denmark, Hillerød, Denmark). No nationwide studies concerning the TRUE test have previously been reported.

Objectives

To determine the prevalence of sensitizations to JBS 2015 allergens from 2015 to 2018.

Methods

We investigated JBS 2015 patch test results using the web‐registered Skin Safety Care Information Network (SSCI‐Net) from April 2015 to March 2019.

Results

Patch test results of 5865 patients were registered from 63 facilities. The five allergens with the highest positivity rates were gold sodium thiosulfate (GST; 25.7%), nickel sulfate (24.5%), urushiol (9.1%), p‐phenylenediamine (PPD; 8.9%), and cobalt chloride (8.4%). The five allergens with the lowest positivity rates were mercaptobenzothiazole (0.8%), formaldehyde (0.9%), paraben mix (1.1%), mercapto mix (1.1%), and PPD black rubber mix (1.4%).

Conclusions

Nickel sulfate and GST had the highest positivity rates. The JBS 2015, including a modified TRUE test, is suitable for baseline series patch testing.
An analytically derived delineation of the West African Coastal Province based on bivalves
Authors: Caballero‐Herrera José Antonio , Olivero Jesús , von Cosel Rudo , Gofas Serge
Published: December 2021

Aim

To assess the pattern of biotic regions (BR) and their boundaries, to detect chorotypes and to relate these patterns to key environmental factors.

Location

Eastern Atlantic Ocean.

Time period

Recent.

Taxon studied

Bivalvia.

Methods

Distributions were scored for 595 species. Operational geographical units are classified hierarchically using Baroni‐Urbani & Buser similarity index, clusters were assessed for statistical significance with the ‘RMacoqui 1.0’ software using G tests of independence, and chorotypes were inferred likewise from similarity between species distributions.

Results

Three strong biotic boundaries delimit four BR: (1) European Atlantic and Mediterranean; (2) West African, from western Sahara to southern Angola; (3) Baia dos Tigres/Namibia; and (4) Saint Helena/Ascension. The West African BR is subdivided by two weak boundaries into three subordinate BR: the tropical region proper, the north‐western African transition zone and the cluster (southern Angola/São Tomé/Cape Verde Islands). Of the 429 species present in West Africa, 261 (60.7%) are endemic, and 19 genera (7.2%) are endemic. Sixteen chorotypes were identified; the European BR is correlated with chorotypes C5 (149 species mostly European and Mediterranean) and C3 (38 species mostly in northern Europe), whereas the West African BR is mainly characterized by chorotype C6 (221 species). Some discontinuous distribution patterns of tropical West African species were identified as chorotypes, but subordinate to chorotype C6. The West African BR is mainly characterized by sea surface temperature and chlorophyll; characterization without the islands also involved the extensive sandy coast. The north‐western African transition region is characterized by an arid climate and few rivers and influenced by seasonal upwelling. The cluster of southern Angola, Sao Tomé and Cape Verdes contrasts with the remainder of West Africa in having a predominantly rocky shore.

Main conclusions

The present analyses provide an objective regionalization based on species occurrences, which supports the traditional recognition of West Africa as a major biotic region with a high level of endemism. Attention is called on that the unique endemic component is insufficiently represented in current marine protected areas.
