AbstractTo identify individual differences and potential factors influencing age-related cognitive decline and disease, we created MindCrowd. MindCrowd is a cross-sectional web-based assessment of simple visual (sv) reaction time (RT, index of processing speed) and paired-associate learning (PAL, index of verbal episodic memory). svRT and PAL results were combined with 22 survey questions. Analysis of MindCrowd’s svRT data revealed education and reported stroke as potential modifiers of changes in processing speed and memory from younger to older ages (ntotal=75,666,nwomen= 47,700,nmen= 27,966; ages 18-85 years old, mean (M)Age= 46.54, standard deviation(SD)Age= 18.40). To complement this work, we evaluated complex recognition reaction time (cvrRT) in the UK Biobank cohort (ntotal=158,249nwomen= 89,333nmen= 68,916; ages 40-70 years old,MAge= 55.81,SDAge= 7.72). Similarities between the UK Biobank and MindCrowd were assessed using a subset of the MindCrowd cohort. Labeled UKBb MindCrowd (ntotal=39,795,nwomen= 29,640,nmen= 10,155; ages 40-70 years old,MAge= 56.59,SDAge= 8.16), this subset was carefully selected to mirror the UK Biobank. An identical linear model (LM) was used to assess both cohorts. The LM revealed similarities between MindCrowd and the UK Biobank across most results, despite obvious cohort differences (e.g., US vs. the UK). Notable divergent findings from the UK Biobank included (1) a first-degree family history of Alzheimer’s disease (FHAD) was associated with longer RTs in only. (2) Compared to being a man with more education, being a woman was associated with longer cvrRT length differences observed from younger to older ages. Divergent results from UKBb MindCrowd include more education and reported smoking. More education was associated with shorter and smoking longer cvrRTs differences observed from younger to older ages. Collected with our prior work, MindCrowd is beginning to reveal the intricate network connecting processing speed, memory, and cognition to healthy and pathological brain aging.

AbstractWe present an exploratory cross-sectional analysis of the effect of season and weather on Freesurfer-derived brain volumes from a sample of 3,279 healthy individuals collected on two MRI scanners in Hartford, CT, USA over a 15 year period. Weather and seasonal effects were analyzed using a single linear regression model with age, sex, motion, scan sequence, time-of-day, month of the year, and the deviation from average barometric pressure, air temperature, and humidity, as covariates. FDR correction for multiple comparisons was applied to groups of non-overlapping ROIs. Significant negative relationships were found between the left- and right-cerebellum cortex and pressure (t = −2.25, p = 0.049; t = −2.771, p = 0.017). Significant positive relationships were found between left- and right-cerebellum cortex and white matter between the comparisons of January/June and January/September. Significant negative relationships were found between several subcortical ROIs for the summer months compared to January. An opposing effect was observed between the supra- and infra-tentorium, with opposite effect directions in winter and summer. Cohen’s d effect sizes from monthly comparisons were similar to those reported in recent psychiatric big-data publications, raising the possibility that seasonal changes and weather may be confounds in large cohort studies. Additionally, changes in brain volume due to natural environmental variation have not been reported before and may have implications for weather-related and seasonal ailments.

Published: July 2020

AbstractGrowth Differentiation Factor-15 (GDF-15), though emerged as a novel marker in gynecological cancers, is yet to be recognized in clinical diagnostics. Eligible studies were sorted from multiple online databases, namely PubMed, Cochrane, ClinicalTrials.gov, Google Scholar, Web of Science, Embase, Scopus, LILACS, OpenGrey. From six studies, histopathologically diagnosed cases without prior treatment, and with diagnostic accuracy data for GDF-15 in gynecological cancers, were included. Our meta-analysis shows that GDF-15 has pooled diagnostic odds ratio of 12.74 at 80.5% sensitivity and 74.1% specificity, and an AUC of 0.84. Hence, GDF-15 is a potential marker to differentiate gynecological malignancy from non-malignant tumors.
Rapid Systematic Review Exploring Historical and Present Day National and International Governance during Pandemics
Authors: Lowry Elizabeth , Taddese Henock , Bowman Leigh R. 
Published: July 2020

AbstractIntroductionPandemics have plagued mankind since records began, and while non-communicable disease pandemics are more common in high-income nations, infectious disease pandemics continue to affect all countries worldwide. To mitigate impact, national pandemic preparedness and response policies remain crucial. And in response to emerging pathogens of pandemic potential, public health policies must be both dynamic and adaptive. Yet, this process of policy change and adaptation remains opaque. Accordingly, this rapid systematic review will synthesise and analyse evaluative policy literature to develop a roadmap of policy changes that have occurred after each pandemic event, throughout both the 20th and 21st Century, in order to better inform future policy development.Methods and AnalysisA rapid systematic review will be conducted to assimilate and synthesise both peer-reviewed articles and grey literature that document the then current pandemic preparedness policy, and the subsequent changes to that policy, across high-, middle- and low-income countries. The rapid review will follow the PRISMA guidelines, and the literature search will be performed across five relevant databases, as well as various government websites to scan for grey literature. Articles will be screen against pre-agreed inclusion/ exclusion criteria, and data will be extracted using a pre-defined charting table.Ethics and DisseminationAll data rely on secondary, publicly available data sources; therefore no ethical clearance is required. Upon completion, the results of this study will be disseminated via the Imperial College London Community and published in an open access, peer-reviewed journal.Article SummaryStrengths and Limitations of this StudyThis systematic review protocol is the first to focus on a longitudinal analysis of pandemic preparedness policy development across low, middle and high income country settingsThis protocol and subsequent review benefit from increased transparency, a systematised strategy (PRISMA), and a reduction in the risk of bias, through publication in an open access journalThis review will also capture grey literature - studies published outside peer-reviewed journalsThis review protocol and methodology is not as robust as systematic reviews, therefore will lack some of the robustness often associated will classical systematic reviewsRegistration NumberOpen Science Framework: 10.17605/OSF.IO/VKA39
Peer-to-peer evaluations as narcissistic devices: fabricating an entrepreneurial community
Authors: Van den Bussche Penelope , Dambrin Claire 
Published: July 2020

PurposeThis paper investigates online evaluation processes on peer-to-peer platforms to highlight how online peer evaluation enacts neoliberal subjects and collectives.Design/methodology/approachThe paper uses netnography (Kozinets, 2002) to study the online community of Airbnb. It is also based on 18 interviews, mostly with Airbnb users, and quantitative data about reviews.FindingsResults indicate that peer-to-peer platforms constitute biopolitical infrastructures. They enact and consolidate narcissistic entrepreneurs of the self through evaluation processes and consolidating a for-show community. Specifically, three features make evaluation a powerful neoliberal agent. The object of evaluation shifts from the service to the user's own worth (1). The public nature of the evaluation (2) and symetrical accountability between the evaluator and the evaluatee (3) contribute to excessively positive reviews and this keeps the market fluid.Social implicationsThis paper calls for problematization of the idea of sharing in the so-called “sharing economy”. What is shared on peer-to-peer platforms is the comfort of engaging with people like ourselves.Originality/valueThis paper contributes to the literature on online accounting by extending consideration of evaluation beyond the review process. It also stresses that trust in the evaluative infrastructure is fostered by narcissistic relationships between users, who come to use the platform as a mirror. The peer-to-peer context refreshes the our knowledge on evaluation in a corporate context by highlighting phenomena of standardized spontaneity and euphemized evaluation language. This allows evaluation processes to incorporate a market logic without having to fuel competition.
Hedonic, emotional and willingness-to-pay response to beers of a different type in Brazil
Authors: Zanetta Luis D'Avolgio , Umebara Matheus Takamori Costa , Costa João Paulo , Takeda Douglas Koji , Da Cunha Diogo Thimoteo 
Published: July 2020

PurposeThe purpose of this paper was to evaluate the differences between common Brazilian beer and pure malt beer in the responses of hedonic scaling, willingness to pay and emotional response.Design/methodology/approachTwo types of beer were selected to be tested – a common beer: Pilsen Skol and pure malt beer: Pilsen Eisenbahn. All the analysis was conducted under three labeling conditions: blind; labeled; inverted label with 70 participants in each test. A nine-point hedonic scale evaluated the acceptance. The consumer was questioned how much he/she would be willing to pay for a bottle of beer that he/she tasted. A questionnaire was elaborated based on the EsSense profile to evaluate emotions; 25 emotions were evaluated using a five-point scale. The socioeconomic status was defined based on consumer's household characteristics.FindingsThe acceptance score, positive emotions and willingness to pay were higher for pure malt beer in the labeled test and for common beer (labeled as pure malt) in the inverted test. The findings highlight that information, such as beer type and socioeconomic status, could influence consumer responses by altering hedonic perceptions, emotions and commercial value attributed to different beers. In general, the beer type did not affect the evaluated variables.Practical implicationsBrewing industry should explore in their marketing strategies and state clearly the pure malt label. In restaurants, owners can explore pure malt beers as a strategy for garnering different customer profiles. Technological and production investments should be encouraged to reduce the product price, favoring the final consumer.Originality/valueThis study contributes to understanding the growth in the consumption of pure malt beers in Brazil. Moreover, it brings an overview of the influence of the label/information on regular Brazilian consumers.
Re-emergency of Ebola in the Democratic Republic of Congo: synergizing the preparedness and response measures with the sustainable development goals
Authors: Balikuddembe Joseph Kimuli 
Published: July 2020

PurposeThis paper attempts to discuss the synergies between the sustainable development goals (SDGs) and Ebola preparedness and response – with a specific outlook about how the five (5) targets in SDG.3 can be prioritized and integrated into the measures taken against the battle of Ebola virus disease (EVD) in the Democratic Republic Congo (DRC) as well as any other sporadic health disasters and emergencies elsewhere.Design/methodology/approachThis paper draws on the published literature, including reports, peer-reviewed articles, statistical data and relevant documents identified from authenticated sources.FindingsSustainable development, which is the nitty-gritty of SDGs, is underscored as a germane in almost all regional and international frameworks. However, as traditional natural hazards persist, alongside the persistence of civil conflicts and instability, socioeconomic challenges such as EVD pose serious hindrances to SDGs, and achieving them by 2030 might be a deferred dream, especially in low- and middle-income countries such as DRC.Practical implicationsThis paper will help to inform the decisions of bureaucrats at different levels, especially those aimed at promoting and integrating health into sustainable development.Originality/valueThe recent 2018 EVD outbreaks in DRC, which galvanized the regional and global attention, call for an approach that elucidates an interaction between the SDGs and countermeasures of responding to this deadly disease in the DRC and elsewhere.

Published: July 2020

PurposeThe present study proposes the analysis of DRM strategies that had been implemented into subnational development plans and public policy instruments in the States of Chiapas and Tabasco, located in Southeast Mexico. It describes the methodological phases for the implementation of those strategies and the participatory process, with a multi-level approach, carried out with multiple stakeholders and UNDP advisory.Design/methodology/approachFor this research, two case studies were developed to highlight the factors which make successful DRM in development plans and policies. It included the compilation and review of documents generated by UNDP-PMR program on the mainstreaming process in the past four years, interviews with key actors in the states of Chiapas and Tabasco, such as governmental officers, national and international ONG's, UN agencies and rural communities' leaders.FindingsThe review of these case studies demonstrate that for developing countries like Mexico, the process to strengthening institutions setting, needs being present in the field and creating alliances and synergies to generate advocacy processes from a capacity development approach. Having not only an output approach in projects but also mainly an impact strategy, both at the local and the sectoral levels, along with a mid-term timeline and budget, are some of the hallmarks of UNDP-PMR program work.Originality/valueThis study showed two original experiences of mainstreaming DRM into subnational development policies in high risk contexts. These experiences had the participation of multiple stakeholders from local governments and communities. Nowadays, these two experiences are being implemented in the territories despite political administration changes in the last years.
A symbiotic organisms search algorithm-based design optimization of constrained multi-objective engineering design problems
Authors: Ustun Deniz , Carbas Serdar , Toktas Abdurrahim 
Published: July 2020

PurposeIn line with computational technological advances, obtaining optimal solutions for engineering problems has become attractive research topics in various disciplines and real engineering systems having multiple objectives. Therefore, it is aimed to ensure that the multiple objectives are simultaneously optimized by considering them among the trade-offs. Furthermore, the practical means of solving those problems are principally concentrated on handling various complicated constraints. The purpose of this paper is to suggest an algorithm based on symbiotic organisms search (SOS), which mimics the symbiotic reciprocal influence scheme adopted by organisms to live on and breed within the ecosystem, for constrained multi-objective engineering design problems.Design/methodology/approachThough the general performance of SOS algorithm was previously well demonstrated for ordinary single objective optimization problems, its efficacy on multi-objective real engineering problems will be decisive about the performance. The SOS algorithm is, hence, implemented to obtain the optimal solutions of challengingly constrained multi-objective engineering design problems using the Pareto optimality concept.FindingsFour well-known mixed constrained multi-objective engineering design problems and a real-world complex constrained multilayer dielectric filter design problem are tackled to demonstrate the precision and stability of the multi-objective SOS (MOSOS) algorithm. Also, the comparison of the obtained results with some other well-known metaheuristics illustrates the validity and robustness of the proposed algorithm.Originality/valueThe algorithmic performance of the MOSOS on the challengingly constrained multi-objective multidisciplinary engineering design problems with constraint-handling approach is successfully demonstrated with respect to the obtained outperforming final optimal designs.

Learning outcomes
Expected learning objectives students will be able to examine the possible reasons for a company’s poor performance using relevant business tools. Students will be able to critically assess the role of technology and social media in the gem and jewellery industry in Dubai. Students will be able to analyse the customer segmentation approach used by five diamonds and to critically analyse its advantages and disadvantages. Students will be able to use the SWOT framework to identify the key weaknesses of and threats to five diamonds and identify the strengths and opportunities that the company needed to capitalize on, to be more competitive in the industry and generate high profitability. Students will be able to critically analyse the fit between the firm’s current business strategy and its business environment and develop a “turnaround” strategy.

Case overview/synopsis
Five diamonds were a trading company that dealt in gems and jewellery, natural pearls and branded watches. The company had been founded by Mustafa Al Fardan in 2003 and was currently run by his son Mohammed Al Fardan who held the position of General Manager. The company was based in Dubai, United Arab Emirates (UAE) with two local branches and eight international branches in China, France, India, Switzerland, Hong Kong and the UK. The branches were located in Palm Strip Jumeirah and in the Jumeirah Al Naseem Hotel, in the Umm Sequim area. The Palm Strip Jumeirah region is one of the largest and crowded areas in Dubai with world-class facilities such as hotels, clinics, restaurants, beaches and clubs, making it a perfect location for tourists. The Umm Sequim region is in the same area where the iconic seven-star hotel, Burj Al Arab, is located. The place is also a “must be” place for tourists and has recorded a significant increase in traffic at different times of the year. Despite their strong presence locally and internationally, the firm was facing fierce competition from the hostile business environment. Industry trends and the business environment were changing the local and global gems and jewellery industry landscape. These changes had offset five diamonds’ business strategy and its long-held business tradition. As a result, the company yearly profit had started to plummet. The company needed to revise its existing business strategy and the way it operated in the market. Failure to do so would have resulted in the firm missing the huge growth opportunity and also put itself into jeopardy.

Building maintenance practices in Malaysia: a systematic review of issues, effects and the way forward
Authors: Hauashdh Ali , Jailani Junaidah , Abdul Rahman Ismail , AL-fadhali Najib 
Published: July 2020

PurposeIn recent years, there have been many concerns about issues surrounding building maintenance, which are continually increasing. However, there is a lack of comprehensive studies on building maintenance issues, their effects and the way forward. Therefore, the purpose of this paper is to carry out a comprehensive review of building maintenance issues, their effects and the way forward. It also aims to develop a conceptual model that can support future research.Design/methodology/approachA systematic review of the literature published from 2009 to 2019 was carried out. Five relevant databases were searched, based on this study's search terms, and a narrative synthesis of the results from the included studies was carried out. Studies were eligible for inclusion if they fulfilled the inclusion criteria of this systematic review.FindingsThis study has identified and classified building maintenance issues, their effects and the way forward, and also developed a conceptual model that demonstrates the association between issues, their effects and the way forward. The way forward of the conceptual model focuses on effective management, technical capability, development of human resources and cost optimisation.Originality/valueThis paper addresses an important topic: the aspect in which it differs from existing studies is that, in the latter, the researchers studied a single sub-issue, whereas this systematic review includes a comprehensive study of building maintenance issues. Furthermore, this review has demonstrated how the way forward can moderate issues and their effects.
Employers' perspectives on work readiness in construction: are project management graduates hitting the ground running?
Authors: Borg Jessica , Scott-Young Christina M. 
Published: July 2020

PurposeThere is a need for graduates who can quickly adjust and thrive within the current increasingly dynamic project-based workplaces. The purpose of this paper is to present the employers' perspectives on the work readiness of project management graduates entering the Australian construction industry.Design/methodology/approachTo gain the industry's perspective, qualitative in-depth interviews were conducted with key informants from 18 different construction companies that employ project management graduates.FindingsThematic analysis revealed that from the employers' perspective, work readiness constitutes (1) empathic communication, (2) passion and (3) technical construction knowledge. Graduates' areas of strength (e.g. application of technology) and weakness (e.g. responding to confrontational situations) were identified.Practical implicationsThe findings provide valuable insights into employers' perspectives of the work readiness of project management graduates which can serve as feedback to universities to assist in aligning their educational programmes with industry needs.Social implicationsWhile employers recognize that the responsibility for fostering work readiness should be shared between themselves and universities, this research highlights that currently adequate collaboration does not occur. This paper advocates for both universities and employers to be open to engaging in the conversation to enhance graduate work readiness.Originality/valueNo research to date has investigated the work readiness of project management graduates, nor whether their work readiness levels meet employers' requirements. This paper addresses this gap.
