Authors: Silva Alexandre , Figueiredo Elisabete , Truninger Mónica , Eusébio Celeste , Forte Teresa 
Published: April 2021

PurposeThe purpose of this paper is to explore and typify the characteristics and diverse features of urban speciality stores selling rural provenance food, taking the case of three cities in Portugal.Design/methodology/approachThe study was based on hierarchical cluster analysis, performed upon data collected from a survey to 113 shops, located in Aveiro (n = 15), Lisbon (n = 56) and Porto (n = 42).FindingsThe study identified three clusters of shops according to the type of rural provenance products sold, services provided and clientele characteristics: the wine focused, the rural provenance focused and the generalist. The study confirms that in Portugal, small food retail outlets, with different rural provenance patterns and degrees of specialization have considerably grown in large cities over the last decade.Research limitations/implicationsThe study contributes to typifying urban speciality food stores selling rural provenance products and to addressing critical research gaps on this topic. The study highlights the dynamism of small food retail outlets and their significance, mediating and responding to changing patterns of food consumption in urban spaces.Originality/valueThis study contributes to a better understanding and characterization of food speciality shops in urban settings and their links with rural territories of provenance, an under-researched topic on the food retail literature.

Published: April 2021

Purpose
Virtual reality (VR) offers unique features of a three-dimensional (3D) model during early design stages in the virtual environment with immersive functions. Although the potential of VR is to increase the effectiveness and productivity of the project phases from initial concept design to detailed design preparation. VR adoption in the United Kingdom (UK) Architectural Engineering and Construction (AEC) sector is slow compared to other sectors. This research focuses on ascertaining the drivers and barriers of VR in construction projects in the UK.

Design/methodology/approach
The study adopts an online survey design. It uses Bristol Online Survey (BOS) to create a structured questionnaire that is used to assess UK construction professionals using a convenience sampling technique. Therefore, researcher uses descriptive and inferential technique for data analysis and presentation based on Statistical Package for Social Sciences (SPSS) to analyze the questionnaire.

Findings
The research findings revealed the most significant barriers to VR adoption in UK construction industry were lack of skills/expertise and cultural change. Hence, the main drivers of VR adoption as rated by the professionals in the UK construction industry are improved safety, improved quality and improved productivity.

Practical implications
The identification and assessment of the drivers and barriers to VR adoption could advance VR adoption among construction professionals and other stakeholders of the UK AEC sector. This could also be extended to developing countries, given the status of VR as being in the developing stage.

Originality/value
This study provides valuable insights to construction professionals and stakeholders to plan actions that could enhance the drivers and mitigate the barriers of VR. This study's main contribution is to group and classify various drivers and barriers into easily understood categories, in order to potentiate the drivers and reduce the barriers effectively. The groupings could be used as benchmarks in similar studies in developing countries.
Urbanization in Saudi Arabia and sustainability challenges of cities and heritage sites: heuristical insights
Authors: Alqahtany Ali , Aravindakshan Sreejith 
Published: April 2021

PurposeThe purpose of this paper is to explore the trajectories of the urbanization process in Saudi Arabia in its regional context from the unification of the country by King Abdul Aziz Al Saud in 1932 to the present time, and the urbanization impact on the status and management of cultural heritage in the Kingdom.Design/methodology/approachOur study design integrated a well-articulated theoretical frame of sustainability to gain a heuristical understanding of urbanization in Saudi Arabia, and its link to cultural heritage. The methodological approach was mixed in nature involving (1) literature search and review, (2) analysis of public documents and databases, (3) analysis of photographs and (4) expert interviews.FindingsOne of the most obvious findings reached in this study is that there is considerable trade-off between heritage site conservation, population and economic demand for increased urbanization. Hence, with increasing urbanization pressures, the value of the heritage site may be rethought based on Saudi Arabia's economic and cultural conservation perspectives.Research limitations/implicationsSince our data are mostly of textual narrative in origin, precise predictions were difficult or impossible for many reasons such as non-linearity, and non-equilibrium dynamics, context and scale dependence as well as the historical exigency of urbanization. However, the same theoretical framework can be applied to appropriate longitudinal/ time series data for predictive analyses, which can be taken up as a future research agenda.Originality/valueThis paper analyzes the urbanization process and sustainability challenges of cultural heritage sites employing a mixed methodological approach, embedded in a holistic theoretical framework of sustainability.
Health disparities among older women in India during the COVID-19 pandemic
Authors: Tomar Aditi , Hossain Md Mahbub 
Published: April 2021

PurposeOlder women in India continually experience disparities in health. The legally enforced lockdown in India has impacted both physical and psychosocial well-being of the populace. Amid the restrictions on mobility during the lockdown, older adults are presented with challenges such as impaired access to healthcare services, nonavailability of attendants and prolonged social isolation. Due to these challenges, disparities related to gender and age may considerably widen. The potential health threats may particularly afflict older women, who bear a disproportionate threat to illnesses, compared to their male counterparts.Design/methodology/approachThis commentary explores how health threats among older Indian women may have worsened during the lockdown. The authors also propose recommendations for expanding health and social care to older women in India.FindingsApproaches aimed at strengthening gerontological social work must be duly adopted, especially during the ongoing pandemic. Public institutions and development partners should utilize and if needed, overhaul existing resources and policies to adequately serve this marginalized group. Older women, especially those residing in unbearable circumstances, should be identified and brought under comprehensive care coverage within the social landscape.Originality/valueThis article proposes recommendations to foster gerontological social work among older Indian women.
Do female directors drive intellectual capital performance? Evidence from Indian listed firms
Authors: Smriti Neha , Das Niladri 
Published: April 2021

PurposeThe purpose of this paper is to investigate the significance of board gender diversity (BGD) on the firm's intellectual capital (IC) performance of 272 Indian firms listed on the National Stock Exchange during 2007–2019. Considering the recent regulatory amendment by the Indian regulatory system (Security Exchange Board of India, 2018) which mandates at least one female independent directors on boards of all listed companies.Design/methodology/approachBased on theories and literature reviews, hypotheses were developed. This paper uses the proportion of female director on board and proportion of female independent directors to measure BGD and modified value-added intellectual coefficient (MVAIC) methodology to measure firms' IC performance. Two-step system-generalised method of moment panel data regression analysis has been employed to identify the variables that significantly affect IC performance.FindingsThis paper finds female representation on boards has a significant impact on MVAIC; capital employed efficiency shows the strongest association with female directors on board, followed by structural capital efficiency and human capital efficiency, while relational capital efficiency shows no significant effect. The results further demonstrate that female independent director has a significant but negative impact on IC.Research limitations/implicationsAs the study is limited to the listed firms of an emerging economy with a mandatory female quota for boards. Thus to increase the generalizability of findings, future research can be extended to include all listed and non-listed firms from another emerging economy with a mandatory female quota.Practical implicationsFrom the practical perspective, this study bridges the gap between theory and practice in terms of providing a deeper understanding to the policymakers and Indian regulatory bodies like the Ministry of Corporate Affairs and Securities Exchange Board on the importance of including female members on board as a vital contributing factor for leveraging firm's intangible performance.Originality/valueUsing resource dependency theory and agency, this study extends the literature on IC efficiency and female representation on boards by presenting the research outcome for Indian listed firms. This paper, addressing the recent changes introduced by Indian regulators and using the female independent directors on board, is amongst the first attempts to assess the relevance of BGD and IC performance. This issue has still not been discussed and analysed by researchers in India.

Authors: Reguera-Alvarado Nuria , Bravo-Urquiza Francisco 
Published: April 2021

PurposeThe main objective of this paper is to analyze the influence of multiple directorships, as a critical component of board social capital, on CSR reporting. This study also explores the moderating effect of certain board attributes on multiple directorships.Design/methodology/approachThe authors’ sample is composed of Spanish listed firms in the Madrid Stock Exchange for the period 2011–2017. A dynamic panel data model based on the Generalized Method of Moments (GMMs) is employed.FindingsRelying on a resource dependence view, the authors’ results highlight an ambiguously positive association between multiple directorships and the level of CSR reporting. In particular, this relationship is positively moderated by both board size and gender diversity.Research limitations/implicationsThese findings contribute to academic debates concerning the value of board members intellectual capital. In particular, the authors emphasize the importance of board social capital, as well as the need to consider the context in which directors make decisions.Practical implicationsThis evidence may prove helpful to firms when configuring the board of directors, and for regulators and professionals when refining their legislations and recommendations.Originality/valueTo the best of the authors' knowledge, this is the first study that empirically analyzes the impact of an important element of board social capital, such as multiple directorships, on CSR reporting, which has become crucial in financial markets.
Land‐use history alters the diversity, community composition and interaction networks of ectomycorrhizal fungi in beech forests

Published: April 2021

Abstract

Forests have expanded across Europe over the last centuries as a consequence of farmland (agricultural and pasture) abandonment. Agricultural practices usually increase soil fertility and reduce the diversity and abundance of ectomycorrhizal (ECM) fungi, essential mutualists of many woody species in temperate and Mediterranean forests. The recovery of this biotic interaction after the cessation of human activities is, thus, crucial for the re‐establishment of functional forest ecosystems.

Here we addressed the legacies of past land use and the recovery of the mutualism between ECM fungi and Fagus sylvatica trees in recent beech forests (<50 years) in Northeast Spain. Soil and root samples were collected in six long‐established and eight recent beech forests to analyse soil abiotic properties and the ECM fungi associated with beech roots (Illumina DNA metabarcoding of ECM tips).

Up to 609 amplicon sequence variants (ASVs) of ECM fungi were identified, with 220 ASVs found in both forest types. Recent forests had a significantly lower soil organic matter and phosphorus content, which had a significant effect on the community structure of ECM fungi in beech roots. Moreover, beech trees in recent forests interacted with less fungal taxa but had a higher relative abundance of Ascomycota. Tarzetta spp. (Ascomycota, Pezizales) and Lactarius blennius (Basidiomycota, Russulales) emerge as the particular taxa associated with recent and long‐established forests respectively.

More specialized mutualistic networks with a lower species normalized degree were found in recent forests, which might result in a lower quality and resilience of the ECM mutualism.

Synthesis. Land‐use history modulated the mycorrhizal symbiosis in regenerating beech forests through changes in soil organic matter and nitrogen, which were the main drivers of the differences in fungal community composition and functional types associated with beech trees in recent forests.
Kaluza's Law and Secondary Stress
Authors: Goering Nelson 
Published: April 2021

AbstractKaluza’s law is a proposed restriction in the metre ofBeowulfagainst the resolution of light‐heavy sequences: words likecyning‘king’ can only resolve and count as the equivalent of a single heavy syllable under more restricted circumstances than can words such aswudu‘wood’. There has been debate about how to define these ‘restricted circumstances’, with many investigators claiming that this limitation holds only under ‘secondary stress’ (sometimes broadened to include subordinated stress in general). This article reviews the operation of Kaluza’s law inBeowulf, arguing that the correct conditioning is the position immediately following a heavy syllable. The level of stress carried by the (non‐)resolving sequence is irrelevant. A phonological explanation for this restriction may be that the resolution ideally produces bimoraic (light‐light) units; accordingly, resolution of light‐heavy sequences, which is anomalous from a typological and phonological perspective, is only permitted in word‐initial position, or in metrical equivalents.
US federal farm payments and farm size: Quantile estimation on panel data
Authors: Haque Samiul 
Published: April 2021

AbstractThe marginal effect of government payments on farm size of US corn/soy and wheat producers is currently contested. This paper uses a quantile estimator with a restricted access panel dataset. Payments are positively associated with farm size; the association is statistically significant at select percentiles of the farm size distribution, but the statistical significance is not systematically related to farm size. Although the marginal effect is qualitatively larger for bigger farms, their differences are not statistically significant. This study does not provide any empirical evidence to suggest that federal farm dollars cause (i) only large farms to grow bigger or (ii) large farms to grow more than small farms.

Published: April 2021

AbstractLudwig's angina is characterized by inflammation of the sublingual and submandibular spaces and is mainly caused by odontogenic infection, which leads to cellulitis of the soft tissues of the floor of the mouth and the neck. This causes asphyxia due to elevation and posterior deviation of the tissues of the floor of the mouth. We report a fatal case of airway obstruction due to Ludwig's angina. A woman in her forties who had no physical complications, but had a mental illness, was undergoing outpatient dental treatment for caries in the first premolar of the left mandible. She was admitted to a psychiatric hospital because of insomnia caused by pain, where she developed cardiopulmonary arrest while sleeping and died 14 days after onset of the dental infection. Postmortem computed tomography (PMCT) prior to autopsy showed swelling of the soft tissues—from the floor of the mouth to the oropharyngeal cavity, the supraglottic larynx, and the prevertebral tissue. Autopsy revealed a markedly swollen face and neck, an elevated tongue, and a highly edematous epiglottis and laryngopharyngeal mucosa. There was also cellulitis and abscess of the facial, suprahyoid, and neck musculature, which suggested that the cause of death was asphyxiation due to airway obstruction. This was an alarming case, with mental illness leading to risk of severe odontogenic infection, and in which obesity and use of antipsychotic medication might have acted synergistically leading to airway obstruction. This is also a case of Ludwig's angina captured by PMCT, which has rarely been reported.

Published: April 2021

AbstractAndrogen receptor (AR) is an important target for the treatment of prostate cancer, and mutations in the AR have an important impact on the resistance of existing drugs. In this work, we performed molecular dynamics simulations of the existing marketed antiandrogens flutamide, nilutamide, bicalutamide, enzalutamide, apalutamide, darolutamide, and its main metabolite ORM15341 in complex with the wild‐type and F876L mutant AR. We calculated the residue‐specific binding free energy contribution of the wild‐type and mutant ARs with the AS‐IE method and analyzed the hotspot residues and the binding free energy contributions of specific residues before and after the mutation. In addition, we analyzed the total binding obtained by adding residue binding energy contributions and compared the results with experimental values. The obtained residue‐specific binding information should be very helpful in understanding the mechanism of drug resistance with respect to specific mutations and in the design of new generation drugs against possible new mutations.
‘They became my second family’: Children's relational lives and relationship‐based practice in residential care in the Philippines
Authors: Roche Steven , Flynn Catherine , Mendes Philip 
Published: April 2021

AbstractDespite the widespread utilization of residential care in the Philippines, little is known about the lives and circumstances of children living within these contexts. In response, this article presents an analysis of children and young people's experiences of living in residential care, specifically focusing on their social networks, relationships and the relationship‐based practices of their caregivers. Drawing on 50 qualitative interviews with children and young people currently or previously living in residential care, as well as a range of social workers and programme staff, this study identifies the highly relational lives of children and young people who cite extensive and close relationships with residential care staff, peers and family. Analysis reveals that children conceptualize ‘family’ as embodied in their residential care programme, drawing attention to the collective support and security offered, while also detailing the role of their spirituality as an important support. Relationship‐based practices are utilized by caregivers who offer long‐term, emotionally close and stable relationships with children to support their well‐being. These findings highlight the centrality of relationship‐based interventions and the maintenance of children's relational lives as a core practice, offering insights into the development of practice in these settings.
The role of intraoperative radiotherapy in advanced rectal cancer: a meta‐analysis
Authors: Fahy Matthew R. , Kelly Michael E. , Power Foley Megan , Nugent Timothy S. , Shields Conor J. , Winter Des C. 
Published: April 2021

AbstractAimPatients with locally advanced and locally recurrent rectal cancer (LARC/LRRC) experience higher rates of local recurrence (LR) and poorer overall survival than patients with primary rectal cancer restricted to the mesorectum despite improved neoadjuvant treatment regimens and radical surgical procedures. Intraoperative radiotherapy (IORT) has been suggested as an adjunctive tool in the surgical management of these challenging cases. However, clear evidence regarding the oncological benefit of IORT is sparse. The aim of this review was to update this evidence in the era of standardized neoadjuvant radiotherapy administration.MethodA systematic review of patients who received IORT as part of multimodal treatment for advanced rectal cancer from 2000 to 2020 and an analysis of IORT and surgery/external beam radiotherapy (EBRT) groups was performed. The primary endpoint was the rate of LR between the two groups.ResultsSeven papers met the predefined criteria. LR was reduced by the addition of IORT when compared with the surgery/EBRT alone group (14.7% vs. 21.4%; OR 0.55, 95% CI 0.27–1.14; p = 0.11). There was no increase in reported genitourinary morbidity, wound issues, pelvic collections or anastomotic leak in those patients who received IORT. Notably, there was no survival difference between the two groups.ConclusionThe addition of IORT to current treatment strategies in the management of patients with LARC/LRRC is associated with a lower rate of locoregional recurrence without increased morbidity. However, this marks a highly selective group of patients, with heterogeneity regarding indications, prior neoadjuvant treatments and/or IORT dosing.
