AbstractImportanceNursing home residents have been disproportionately impacted by the COVID-19 epidemic. Prevention recommendations have emphasized frequent testing of healthcare personnel and residents, but additional strategies are needed to protect nursing home residents.ObjectiveWe developed a reproducible index of nursing home crowding and determined whether crowding was associated with incidence of COVID-19 in the first months of the COVID-19 epidemic.Design, Setting, and ParticipantsPopulation-based retrospective cohort study of over 78,000 residents of 618 distinct nursing homes in Ontario, Canada from March 29 to May 20, 2020.ExposureThe nursing home crowding index equalled the average number of residents per bedroom and bathroom.OutcomesPrimary outcomes included the cumulative incidence of COVID-19 infection and mortality, per 100 residents; introduction of COVID-19 into a home (≥1 resident case) was a negative tracer.ResultsOf 623 homes in Ontario, we obtained complete information on 618 homes (99%) housing 78,607 residents. A total of 5,218 residents (6.6%) developed COVID-19 infection, and 1,452 (1.8%) died with COVID-19 infection as of May 20, 2020. COVID-19 infection was distributed unevenly across nursing homes: 4,496 (86%) of infections occurred in just 63 (10%) of homes. The crowding index ranged across homes from 1.3 (mainly single-occupancy rooms) to 4.0 (exclusively quadruple occupancy rooms); 308 (50%) homes had high crowding index (≥2). Incidence in high crowding index homes was 9.7%, versus 4.5% in low crowding index homes (p<0.001), while COVID-19 mortality was 2.7%, versus 1.3%. The likelihood of COVID-19 introduction did not differ (31.3% vs 30.2%, p=0.79). After adjustment for regional, nursing home, and resident covariates, the crowding index remained associated with increased risk of infection (RR=1.72, 95% Confidence Interval [CI]: 1.11-2.65) and mortality (RR=1.72, 95%CI: 1.03-2.86). Propensity score analysis yielded similar conclusions for infection (RR=2.06, 95%CI: 1.34-3.17) and mortality (RR=2.09, 95%CI: 1.30-3.38). Simulations suggested that converting all 4-bed rooms to 2-bed rooms would have averted 988 (18.9%) infections of COVID-19 and 271 (18.7%) deaths.Conclusions and RelevanceCrowding was associated with higher incidence of COVID-19 infection and mortality. Reducing crowding in nursing homes could prevent future COVID-19 mortality.

ABSTRACTIMPORTANCEIdentifying potential Covid-19 patients in the general population is a huge challenge at the moment. Given the low availability of infected Covid-19 patients clinical data, it is challenging to understand and comprehend similar and complex patterns in these symptomatic patients. Laboratory testing for Covid19 antigen with RT-PCR | (Reverse Transcriptase) is not possible or economical for whole populations.OBJECTIVETo develop a Covid risk stratifier model that classifies people into different risk cohorts, based on their symptoms and validate the same.DESIGNAnalysis of Covid cases across Wuhan and New York were done to identify the course of these cases prior to being symptomatic and being hospitalised for the infection. A dataset based on these statistics were generated and was then fed into an unsupervised learning algorithm to reveal patterns and identify similar groups of people in the population. Each of these cohorts were then classified and identified into three risk levels that were validated against the real world cases and studies.SETTINGThe study is based on general population.PARTICIPANTSThe adult population were considered for the analysis, development and validation of the modelRESULTSOf 1 million observations generated, 20% of them exhibited Covid symptoms and patterns, and 80% of them belonged to the asymptomatic and non-infected group of people. Upon clustering, three clinically obvious clusters were obtained, out of which the Cluster A had 20% of the symptomatic cases that were classified into one cohort, the other two cohorts, Cluster B had people with no symptoms but with high number of comorbidities and Cluster C had people with few leading indicators for the infection with few comorbidities. This was then validated against 300 participants whose data we collected as a part of a research study through our Covid-research tool and about 92% of them were classified correctly.CONCLUSIONA model was developed and validated that classifies people into Covid risk categories based on their symptoms. This can be used to monitor and track cases that rapidly transition into being symptomatic which eventually get tested positive for the infection in order to initiate early medical interventions.
Buy one painting, get two names. On the valuation of artist collaborations in the art market
Authors: Radermecker Anne-Sophie V. 
Published: June 2020

PurposeTo analyze the market reception of multi-authored works of art through the lens of collaborative old master paintings (“formal/prestige collaboration”). This paper tests whether multi-authored attribution strategies (i.e. naming two artists as brand names) affect buyers' willingness to pay differently from single-authored works in the auction market.Design/methodology/approachThis case study focuses on collaborative paintings by Flemish masters, based on a data set comprising 11,630 single-authored and collaborative paintings auctioned between 1946 and 2015. Hedonic regressions have been employed to test whether or not co-branded artworks are differently valued by buyers and how the reputation of each artist might influence valuation.FindingsDespite the opportunity for buyers to purchase one artwork with two brand names, this study reveals that the average value of collaborative paintings is statistically lower than that of single-authored paintings. This is especially true when a reputed master was involved in the collaboration. The present findings suggest that the valuable characteristics of formal collaborations (i.e. double brand name, dual authorship and reputation, high-quality standards) are no longer perceived and valued as such by buyers, and that co-branding can affect the artist brand equity because of a contagion effect. We argue that integral authorship is more valued than partial authorship, suggesting that the myth of the artist as a lone genius is still well-anchored in purchasing habits.Research limitations/implicationsPrestige collaborations are a very particular form of early co-branding in the art world, with limited data available. Further research should consider larger samples to reiterate the analysis on other collaboration forms in order to challenge the current findings.Practical implicationsResearchers and living artists should be aware that brand building and co-branding are marketing strategies that may generate negative effects on prices in the art market. The perceived and market value of co-branded works are time-varying, and depends on both the context of reception of these works and the reputation of the artists at time t.Originality/valueThis market segment has never been considered in art market studies, although formal collaboration is one of the earliest documented forms of co-branding in the art world. This paper provides new empirical evidence from the auction market, based on buyers' willingness to pay, and it further highlights the reception of multi-authored art objects in Western art markets that particularly value individual creators.

Published: June 2020

PurposeThis paper searches for integration methods proposed by different authors that assess the life cycle of a building using models of building information modeling (BIM) and it also compares and discusses them.Design/methodology/approachSystematic literature review (SLR) is selected as the main research method of the present paper, aiming to collect and critically analyze multiple research studies. This paper is not only limited to studies where the whole life cycle has been assessed but also includes other papers which only integrated BIM to analyze carbon footprint, embodied carbon dioxide (CO2) or energy consumption.FindingsTaking into account the countries that have published articles about the subject, it is possible to deduce that it has been studied in all of the continents, except Africa. In comparison with other continents, Asia and Europe have developed more studies. Furthermore, 76% of the 34 selected articles were published in journals and only 24% in conferences proceedings, and the number of papers that relates life cycle assessment (LCA) methods using BIM has grown from 2013 to 2015, proving that the current theme is relevant. Several aspects of this literature review show the need to develop automated processes for LCA of buildings during the project's development phase. There is already a tendency to compare LCA results for buildings applied to BIM models, contributing to decision-making related to alternate projects, selection of materials, suppliers and components from an environmental perspective.Originality/valueIn the current global scenario, it is the notorious negative impact on the environment over the years caused by the architecture, engineering and construction industry (AEC). The integration of BIM–LCA can reduce time and improve the application of environmental analysis. Moreover, the proper application of a LCA method to evaluate the environmental impacts of the project can be hindered due to lack of information in the database about the materials or due to failures in the interoperability between BIM software and the LCA tool.

Policymakers can learn from the country lessons and experiences in agriculture and nutrition policy.Originality/valueThis paper provides one of the only overviews of global policy on agriculture and nutrition during the period 2010–2020.
Hybrid processes for a new era of strategic foresight
Authors: Pinto Jean Paul , Medina Javier 
Published: June 2020

Purpose
This paper aims to propose a new strategic foresight process that combines aspects from science fiction, speculative design and tools linked to organizational processes, first, to generate potential new services and products and, second, to reduce problems associated with the construction of low-impact and irrelevant scenarios for decision-making processes. As a new proposal, it invites reflection and debate.

Design/methodology/approach
After reviewing the literature on the key concepts that represent the essence of strategic foresight, as well as the traditional processes to reflect on the future, a proposal for a new hybrid, integrative foresight process that allows moving from imagination to the materialization of scenarios will be presented.

Findings
The new hybrid process makes evident the need to articulate strategic foresight with other areas of knowledge and management tools to build scenarios with greater impact on decision-making and greater added value from strategic foresight to organizational processes.

Originality/value
The proposed integrative model articulates tools that already exist, but the originality of the proposal lies in that there are no models that integrate science fiction, speculative design, and other organizational tools in a single process.
Financial ratio analysis of law firm's strategy and job satisfaction
Authors: Han Seonghee , Song KiKyung , Whang Eunyoung 
Published: June 2020

PurposeJob satisfaction along with a work–life balance of attorneys in law firms has become an important issue to the legal industry. This paper examines the relationship between strategic positioning of law firms and the job satisfaction of their associates.Design/methodology/approachUsing 1,108 firm year observations of US law firms from 2007 to 2016, this paper examines how a firm's strategic positioning affects the job satisfaction of its associates. The strategic positioning is measured with two financial ratios derived from modified DuPont analysis: revenue per lawyer (RPL) and leverage (LEV). To compare the level of associates' job satisfaction depending on law firms' RPL and LEV, this paper uses t-tests. In addition, this paper adopts OLS regression and simultaneous equations to examine the relation between law firms' strategic positioning and their associates' job satisfaction.FindingsThis paper shows that associates in the law firms with a high LEV strategy have lower job satisfaction because these firms provide a more demanding work environment than in the firms with a high RPL strategy.Originality/valueThis paper first documents empirical evidence that a firm's strategic positioning significantly influences job satisfaction of its employees, using data on the legal industry which is human-capital-intensive and is considered one of the sectors that provide the most notorious work environments.

Published: June 2020

PurposeRestructuring swine and pork value chain plays important role in agriculture reformation of Vietnam, the top global pork-lover and swine producer worldwide. This study aims at investigating the modernization of its entire swine-to-pork value chain.Design/methodology/approachThis study combines the secondary data and primary data. The secondary data included the publications, procurements, databases from both worldwide and in Vietnam. Primary data comprised the results from field-trips in March 2018 and February 2019 that used in-depth interviews with representative key persons of involving stake-holders.FindingsThe prevalence of contract farming, vertical expansion and conglomerate mergers mainly boost vertical coordination in the industry, which creates three hierarchy paradigms of governance named the full- and semi-vertically integrated model, and the formal coordinating relation institution. Consequently, consolidation has occurred and lead the swine and pork value chain toward modernization.Research limitations/implicationsThis study generalizes its first trends of the modernization of the swine-to-pork industry instead of provides its concreted impacts to the involved stakeholders.Social implicationsSwine and pork industries retain historical and socio-political issues in Vietnam. Social problems are going to raise if number of traditional swine producers are failed in the competition from the equipped large-scale producers leading by the giant vertically-integrated contractors.Originality/valueThis study provides the empirical synthesis of the vertical coordination in entitle swine and pork value chain of Vietnam through combining the view of the strategic alliance of the firm and global value chain governance.
Teaching with OER during pandemics and beyond
Authors: Van Allen Jennifer , Katz Stacy 
Published: June 2020

PurposeOpen Educational Resources (OER) are learning materials openly licensed so that others may retain, reuse, revise, remix or redistribute (the 5Rs) these materials. This paper aims to raise awareness of OER by providing a rationale for using these learning materials and a strategy for educators to get started with OER during the collective crisis and beyond.Design/methodology/approachUsing a broad research base and anecdotes from personal experience, the authors make the case that OER improves student access to learning materials and improves the learning experience in both PK-12 and higher education contexts.FindingsThe authors define and describe the benefits of OER to provide practical suggestions educators can implement during the pandemic and beyond.Practical implicationsTo support educators in finding and using OER, this paper highlights repositories that include a breadth of various learning materials across subject areas and educational contexts. The authors provide specific suggestions for finding, personalizing and contextualizing OER.Originality/valueThis work not only provides an overview of OER with particular considerations for educators during the COVID-19 pandemic but also makes the case that OER should be integrated into classrooms beyond the pandemic.
ICT proficiency: perspectives of Tangaza University College librarians in Kenya
Authors: Agava Stanislaus L. , Underwood Peter G. 
Published: June 2020

PurposeThis study aims to assess the information and communications technology (ICT) proficiency of library and information science (LIS) professionals working in Tangaza University College (TUC) Library, Kenya.Design/methodology/approachA qualitative research design using a single case study was adopted in the study, which gathered data through a census. Data were collected using a structured interview.FindingsThe study findings indicated that the majority of TUC librarians have very high ICT competence in basic ICT and some Web technologies; however, they lack technical ICT skills. Furthermore, though ICT courses are offered during LIS professional training, TUC librarians lack opportunities to implement some of their advanced ICT skills. Lack of funding, time, practical lessons, personal interest, training opportunities and ICT obsolescence were highlighted as challenges librarians encounter in their pursuit of acquiring ICT skills.Practical implicationsThe study recommends that regular ICT-related training programmes be conducted for librarians and be offered in the form of workshops, seminars and conferences. Furthermore, there is a need for an academic curriculum in LIS schools to have more practical ICT-related components. Library staff should be encouraged to develop a personal interest in pursuing ICT skills, and librarians should also make use of ICT training opportunities that are freely available online for personal development.Originality/valueThe study is beneficial to those concerned with developing training programmes for librarians to strengthen areas deemed to have shortcomings.
The influence of post-visit emotions on destination loyalty
Authors: Godovykh Maksim , Tasci Asli D.A. 
Published: June 2020

Purpose
The influence of different factors including emotional states on loyalty has been previously discussed in the literature. However, the influence of post-visit emotions evoked by emotional stimuli on tourist loyalty lacks empirical attention. The purpose of this study is to investigate the effects of post-visit emotional stimuli on destination loyalty.

Design/methodology/approach
The study applied an online scenario-based experimental design to identify the impact of positive and negative affective pictorial stimuli on destination loyalty. A sample of 500 adult US residents who visited Orlando within the past 12 months was recruited to take part in the experiment. One-way ANOVA was used to compare the loyalty of three groups, two of which were manipulated with emotional stimuli, positive pictures and negative pictures and one control group with no pictures.

Findings
Results show that it is possible to influence visitor loyalty after visitation. Post-visit exposure to positive emotional stimuli generates higher levels of destination loyalty, while negative emotional stimuli generate lower levels of destination loyalty, in comparison with no stimuli scenario.

Originality/value
The study adds to the literature by providing support for the influence of post-visit emotional stimuli on destination loyalty, which lacked empirical attention, thus, far. As visitor experience lasts much longer than the visit itself, the study results are significant for increasing destination loyalty after the trip.

Published: June 2020

AbstractThe association of psoriasis with thyroid dysfunction has been investigated. However, it remains unclear; some papers indicate it, and others do not. In this study, we evaluate the prevalence of thyroid dysfunction in patients with psoriasis vulgaris (PsV), psoriatic arthritis (PsA), generalized pustular psoriasis (GPP) and erythrodermic psoriasis (EP), and the association of thyroid dysfunction with inflammation. Data on 201 psoriatic patients visiting our hospital from January 2014 to November 2017 (159 men and 42 women; 74 PsV, 42 PsA, 38 GPP and 47 EP) were retrospectively analyzed. Thirty‐three percent of psoriatic patients had thyroid dysfunction. The percentage of patients with thyroid dysfunction was the highest in those with EP (60% EP, 42% GPP, 19% PsA, 19% PsV). The prevalence of thyroid dysfunction decreased significantly when patients switched from EP to PsV or PsA (58% vs 17%; median, 20.5; range, 4–65 months). Most of the patients with thyroid dysfunction had low thyroxine syndrome (serum levels of free thyroxine are low, but serum thyroid‐stimulating hormone level is normal). Patients with thyroid dysfunction demonstrated significantly higher CD3+ and CD4+ T‐cell absolute count levels than those without thyroid dysfunction. Meanwhile, patients with thyroid dysfunction demonstrated lower immunoglobulin (Ig)A and IgM levels than those without thyroid dysfunction. Finally, patients with thyroid dysfunction demonstrated higher elevated serum C‐reactive protein levels than those without dysfunction in total, although there were no statistical differences. Our data indicate that thyroid dysfunction in patients with psoriasis may be associated with inflammation caused by psoriasis.
