Engaging in times of COVID-19 and beyond: theorizing customer engagement through different paradigmatic lenses
Authors: Karpen Ingo Oswald , Conduit Jodie 
Published: July 2020

PurposeThe purpose of this paper is to consider a broadened suite of paradigmatic lenses to help better understand customer engagement during and beyond COVID-19. During this period of uncertainty and economic downturn, many customers are questioning their ways of living and being, and thus businesses are engaging customers in new and evolving ways. To appreciate this broadened realm of engagement requires researchers and businesses to embrace existential humanism as an alternative, yet complementary, paradigmatic lens.Design/methodology/approachThis is a conceptual paper. The authors consider three distinct paradigmatic lenses on human (inter)action—economic rationalism, institutionalism and existential humanism—and apply these lenses to deepen the underlying theorizing of the customer engagement concept. Further, the authors illustrate how customers engage with businesses in distinct ways, seeking meaning congruent with the challenges faced during COVID-19.FindingsThe authors argue that the common tripartite model of cognitive, emotional and behavioral customer engagement, typically informed by reductionist and unilateral paradigmatic lenses, is insufficient to understand why customers seek to engage with businesses during and after COVID-19.Originality/valueIn providing a broader paradigmatic perspective, the authors make a plea for a stronger consideration and activation of spiritual engagement in marketing. The current COVID-19 environment challenges extant philosophical assumptions of engagement theorizing, which we address by way of existential humanism. The authors contribute through a more differentiated perspective of engagement, accounting for a broader spectrum of human experience. This enables more informed theorizing across levels of abstraction, while emphasizing diverse avenues for future engagement for a time even beyond COVID-19.
Mind the gap: identifying barriers to students engaging in creative practices in higher education
Authors: Solé Lluís , Sole-Coromina Laia , Poole Simon Ellis 
Published: July 2020

PurposeCreativity is nowadays seen as a desirable goal in higher education. In artistic disciplines, creative processes are frequently employed to assess or evaluate different students' skills. The purpose of this study is to identify potential pitfalls for students involved in artistic practices in which being creative is essential.Design/methodology/approachThree focus groups involving Education Faculty members from different artistic disciplines allowed for the identification of several constraints when creativity was invoked. This initial study used a quantitative approach and took place in the “Universitat de Vic” (Catalonia, Spain).FindingsFindings suggest a correlation with existing literature and simultaneously point at some nuances that require consideration: emerging aspects embedded in creative processes that may help decrease some limiting effects that being creative can generate.Research limitations/implicationsThe main limitations of this research derive from the very nature of the methodological approach. Focus group has been the single used source. Other means of collecting data, such as the analysis of programs, could be used in the future.Originality/valueThis case study, while culturally specific, offers a useful insight into the potential of further work in non-artistic disciplines but crucially across disciplines. It has tremendous value for the development of intercultural understanding in the higher education sector, specifically in terms of assessment.
Maintenance management practices for green building projects: towards hybrid BIM system
Authors: Ismail Zul-Atfi 
Published: July 2020

PurposeIn general, maintenance management is considered as part of the construction sector for the larger service of post-construction activity and process. However, as green building (GB) construction projects grow in scale and complexity, interconnections between the mentioned activities and processes can be noticed in a problematic planning performance management to monitor the GB components for the corrective and preventive maintenance action. Issues often arise during construction activity and pose a problem for the society due to the poor and improper maintenance execution, such as the recent fire in the Grenfell Tower (14 June 2017, about 80 fatalities).Design/methodology/approachThe concept of maintenance management practices of GB and main features of Information and Communication Technology (ICT) tools and techniques were based on analysis of number of literature reviews in GB scenarios.FindingsThe research results described are concerned with an integrated system to analyse information and building a decision-making support in maintenance planning in GB based on robust data collection about concrete failures and causes, provide appropriate planning decision and reduce risks of GB failure throughout the lifetime.Originality/valueThe paper concludes that implementing a research framework for developing such a system can help improve the performance of maintenance planning of GB design, construction and maintenance operations.
‘Your wealth is your health’: the fundamental causes of inequalities in diabetes management outcomes: a qualitative analysis
Authors: O'Donnell Shane 
Published: July 2020

AbstractFundamental Cause Theory (FCT) is among the most influential explanations for health inequalities. The theory posits that the social gradient in health persists because higher‐socioeconomic status (SES) groups are systematically more able to take advantage of new medical innovations and health‐enhancing knowledge due to their greater access to resources. Taking the life histories of people with diabetes (PwD) (N = 17) in the Republic of Ireland as a case study, this paper aims to elucidate the behaviours and agencies underlying 'fundamental causality' through examining how PwD of contrasting SES respond to disease management information. Findings highlight how the most common barriers to effective diabetes control were chronic psychological distress, combined with the cultural significance of alcohol consumption, which was central to both the social and economic subsistence of male participants in particular. However, higher‐SES groups were more likely to experience a 'turnabout' in their life, whereby they could remove themselves from the conditions giving rise to their distress and move into a social space where more health‐enhancing behaviours were possible. It concludes with a discussion of potential mechanisms that may explain why such turnabouts were more likely to occur in the case of higher‐SES groups and the implications for FCT.
Field detection of urease and carbonic anhydrase activity using rapid and economical tests to assess microbially induced carbonate precipitation
Authors: Medina Ferrer Fernando , Hobart Kathryn , Bailey Jake V. 
Published: July 2020

SummaryMicrobial precipitation of calcium carbonate is a widespread environmental phenomenon that has diverse engineering applications, from building and soil restoration to carbon sequestration. Urease‐mediated ureolysis and CO2 (de)hydration by carbonic anhydrase (CA) are known for their potential to precipitate carbonate minerals, yet many environmental microbial community studies rely on marker gene or metagenomic approaches that are unable to determine in situ activity. Here, we developed fast and cost‐effective tests for the field detection of urease and CA activity using pH‐sensitive strips inside microcentrifuge tubes that change colour in response to the reaction products of urease (NH3) and CA (CO2). The urease assay proved sensitive and useful in the field to detect in situ activity in biofilms from a saline lake, a series of calcareous fens, and ferrous springs, finding relatively high urease activity in lake samples. Incubations of lake microbes with urea resulted in significantly higher CaCO3 precipitation compared to incubations with a urease inhibitor, showing that the rapid assay indicated an on‐site active metabolism potentially mediating carbonate precipitation. The CA assay, however, showed less sensitivity compared to the urease test. While its sensitivity limits its utility, the assay may still be useful as a preliminary indicator given the paucity of other means for detecting CA activity in the field. Field urease, and potentially CA, activity assays complement molecular approaches and facilitate the search for carbonate‐precipitating microbes and their in situ activity, which could be applied toward agriculture, engineering and carbon sequestration technologies.
Virtual reality for acute and chronic pain management in adult patients: a narrative review
Authors: Chuan A. , Zhou J. J. , Hou R. M. , Stevens C. J. , Bogdanovych A. 
Published: July 2020

SummaryVirtual reality is a computer‐generated environment that immerses the user in an interactive artificial world. This ability to distract from reality has been utilised for the purposes of providing pain relief from noxious stimuli. As technology rapidly matures, there is potential for anaesthetists and pain physicians to incorporate virtual reality devices as non‐pharmacological therapy in a multimodal pain management strategy. This systematic narrative review evaluates clinical studies that used virtual reality in adult patients for management of acute and chronic pain. A literature search found 690 citations, out of which 18 studies satisfied the inclusion criteria. Studies were assessed for quality using the Jadad and Nottingham‐Ottawa Scales. Agreement on scores between independent assessors was 0.87 (95%CI 0.73–0.94). Studies investigated virtual reality use: intra‐operatively; for labour analgesia; for wound dressing changes; and in multiple chronic pain conditions. Twelve studies showed reduced pain scores in acute or chronic pain with virtual reality therapy, five studies showed no superiority to control treatment arms and in one study, the virtual reality exposure group had a worsening of acute pain scores. Studies were heterogeneous in: methods; patient population; and type of virtual reality used. These limitations suggest the evidence‐base in adult patients is currently immature and more rigorous studies are required to validate the use of virtual reality as a non‐pharmacological adjunct in multimodal pain management.
Politics Disrupted? Collective Intentionality, Inaugural Performativity, and Institutional Receptivity in Undocumented Migrant Struggles
Authors: Swerts Thomas 
Published: July 2020

AbstractCritical scholarship on “the promise‐of‐the‐political” thesis customarily understands undocumented migrant struggles (UMS) as being politically disruptive. However, the question of what gets disrupted, how, by whom, and to what effect tends to be ignored. Building on insights from the empirical literature on UMS and ethnographic research of the “Solidarity March With and Without Papers”, this paper argues that three conditions need to be in place for UMS to be disruptive. First, undocumented activists need to craft collective intentions to challenge the institutional order in and through joint action. Second, protest acts need to effectively interrupt everyday routines symbolising the status quo and instigate replication. Third, UMS need to unsettle and force a response from the order in ways that defy existing institutional logics. These findings are translated into a research agenda that proposes to investigate the relative importance of collective intentionality, inaugural performativity and institutional receptivity for UMS.

AbstractImportanceRetinal ganglion cells endure significant metabolic stress in glaucoma but maintain capacity to recover function. Nicotinamide, a precursor of NAD+, is low in serum of glaucoma patients and its supplementation provides robust protection of retinal ganglion cells in preclinical models. However, the potential of nicotinamide in human glaucoma is unknown.BackgroundTo examine the effects of nicotinamide on inner retinal function in glaucoma, in participants receiving concurrent glaucoma therapy.DesignCrossover, double‐masked, randomized clinical trial. Participants recruited from two tertiary care centres.ParticipantsFifty‐seven participants, diagnosed and treated for glaucoma.MethodsParticipants received oral placebo or nicotinamide and reviewed six‐weekly. Participants commenced 6 weeks of 1.5 g/day then 6 weeks of 3.0 g/day followed by crossover without washout. Visual function measured using electroretinography and perimetry.Main outcome measuresChange in inner retinal function, determined by photopic negative response (PhNR) parameters: saturated PhNR amplitude (Vmax), ratio of PhNR/b‐wave amplitude (Vmax ratio).ResultsPhNR Vmax improved beyond 95% coefficient of repeatability in 23% of participants following nicotinamide vs 9% on placebo. Overall, Vmax improved by 14.8% [95% CI: 2.8%, 26.9%], (P = .02) on nicotinamide and 5.2% [−4.2%, 14.6%], (P = .27) on placebo. Vmax ratio improved by 12.6% [5.0%, 20.2%], (P = .002) following nicotinamide, 3.6% [−3.4%, 10.5%], (P = .30) on placebo. A trend for improved visual field mean deviation was observed with 27% improving ≥1 dB on nicotinamide and fewer deteriorating (4%) compared to placebo (P = .02).ConclusionsNicotinamide supplementation can improve inner retinal function in glaucoma. Further studies underway to elucidate the effects of long‐term nicotinamide supplementation.

AbstractBackgroundWhile Staphylococcus aureus (S. aureus) colonization has been thoroughly studied in atopic dermatitis (AD), where S. aureus is related to flares and considered a trigger factor, S. aureus colonization in hand eczema (HE) has only been sparsely studied.ObjectivesTo examine the 1‐week prevalence of S. aureus colonization in HE patients, and its association with severity, HE subtype, AD, and nasal S. aureus colonization compared with healthy controls.MethodsIn a case‐control study of 50 adult HE patients and 50 healthy controls, bacterial swabs from lesional skin (patients only), non‐lesional skin (dorsal hand), and the nasal cavity were sampled for culturing of S. aureus on days 1, 3, 5 and 8. Participants were characterized by demographics, AD, HE subtype, filaggrin gene mutation status, and HE severity.ResultsTwenty‐seven HE patients (54%) were colonized with S. aureus on the hand compared to one control (2%) (P < .01). Nasal S. aureus colonization was found in 72% of patients and 22% of controls (P < .01). For patients, S. aureus colonization on the hands was associated with an atopic HE subtype and HE severity (P = .01 and P < .01, respectively).ConclusionsBoth hand and nasal S. aureus colonization were highly prevalent among HE‐patients and may have an impact on the persistence of HE.
The rise of coffee in the Brazilian south‐east: tariffs and foreign market potential, 1827–40†
Authors: Absell Christopher David 
Published: July 2020

AbstractDuring the period spanning independence in 1822 to mid‐century, Brazil's south‐east shifted from specializing in the export of cane sugar to coffee. This article explores the mechanism underlying this shift by exploiting a wealth of new monthly data on the Brazilian and international coffee and cane sugar markets during the period 1827–40. It argues that the timing of the coffee boom was driven by a rapid increase in foreign market potential associated with the abolition of the tariff on coffee in the US. It estimates that American tariff reform served to increase coffee exports and African slave imports by around one‐fifth. American firms, with indirect links to the slave trade, rapidly became major players in the export market in Rio de Janeiro, while non‐American firms, traditionally specialized in continental European destinations, turned their sights on the American market.

AimTo evaluate outcomes as well as prognostic factors of transarterial chemoembolization (TACE) in intermediate‐stage hepatocellular carcinoma (HCC) with preserved liver function to determine positioning of TACE.MethodsOf 158 treatment‐naïve patients with intermediate‐stage HCC who received initial TACE from February 2007 to January 2016, 113 patients met the following inclusion criteria: no combined therapy within 4 weeks after initial TACE, and Child–Pugh score under 7. Response rate and overall survival were evaluated. The prognostic factors were investigated in univariate and multivariate analyses using Cox proportional hazards models. The deterioration of liver function after repeated TACE was also evaluated.ResultsThe response rate was 92.7% (complete response, 63.3%; partial response, 29.4%). The median survival time was 45.2 months. Survival rates at 1, 2, and 3 years were 90.4%, 77.0%, and 60.8% respectively. Age ≥ 75 years (P = 0.022), serum α‐fetoprotein level ≥ 200 ng/mL (P = .010), tumor number ≥ 11 (P = 0.008), and heterogeneous enhancement on dynamic computed tomography (P = 0.024) were poor prognostic factors. The deterioration rate of Child–Pugh score and albumin–bilirubin grade was 18.5% and 12.3%, respectively, after the first TACE, 15.6% and 5.1%, respectively, after the second TACE, and 14.5% and 11.1%, respectively, after the third TACE.ConclusionSuperselective TACE can achieve high tumor response rates with prolonged overall survival for patients with intermediate‐stage HCC with preserved liver function. Age, serum α‐fetoprotein level, tumor number ≥ 11, and heterogeneous enhancement on dynamic computed tomography indicated significantly poor prognosis.

AbstractWe report incidence rates for pressure injuries seen in an acute hospital in Singapore that were classified as Stage 3 or Stage 4. The characteristics of patients and the factors that explain variation in the primary outcome of duration of hospital stay are summarized. Existing data were available from Singapore General Hospital for all admissions from January 2016 to December 2019. Univariable analysis was done and a multivariable Poisson regression model estimated. Incidence rates declined from 4.05 to 3.4 per 1000 admissions in the 48 months between 2016 and 2019. The vast majority were community acquired with 75% in admission from the patients' home. Factors that explain variation in length of stay were, ethnicity; site of injury; community versus healthcare associated; inter‐hospital transfer; fracture as reason for admission; and the number of days between admission and assessment of wound by specialist nurse. Stage 3 and 4 injuries arise in a home environment most often and are subsequently managed in acute hospital at high cost. These are novel epidemiological data from a hospital in the tropics where the potential to improve outcomes, implement screening and prevention, and thus increase the performance of health services is strong.
Leaf carbohydrates assimilation and metabolism affect seed yield of rapeseed with different waterlogging tolerance under the interactive effects of nitrogen and waterlogging

Published: July 2020

AbstractWaterlogging is a main factor causing rapeseed (Brassica napus L.) yield loss, and reasonable nitrogen (N) applications can compensate for this loss. To investigate the effects of N rates on seed yield of waterlogged rapeseed, the waterlogging‐tolerant rapeseed variety ZS 9 and sensitive variety GH01 were waterlogged for 0 and 10 days with five leaves at the seedling stage under four N rates (0, 90, 180 and 270 kg/ha). Waterlogging significantly decreased seed yield, while N application can alleviate the yield loss. The yield decrease rate of waterlogged GH01 was greater than that of ZS 9 under the same N rate. During the seedling and bolting stage, the leaf photosynthetic rate (Pn) and ribulose‐1,5‐bisphosphate carboxylase/oxygenase (Rubisco) activity increased, while activities of adenosine diphosphate glucose pyrophosphorylase (AGPase), sucrose synthase (SuSy) and sucrose phosphate synthase (SPS) decreased with more N under the same watering conditions. Compared to the plants without waterlogging, the leaf Pn and Rubisco activity, starch and sucrose contents of waterlogged rapeseed decreased at the two stages; activities of AGPase, SuSy and SPS of waterlogged rapeseed decreased at the seedling while increased at the bolting stage for both the two varieties. At the flowering stage, the Pn, the activities of Rubisco, AGPase, SuSy, SPS and contents of sucrose, starch increased with more N application for both ZS 9 and GH01. Compared to the plants without waterlogging, the Pn and Rubisco activity for waterlogged plants of the two varieties increased; the waterlogged plants of tolerant variety had higher activities of AGPase, SuSy and SPS, while those of sensitive variety was significantly lower. However, the decreased starch and sucrose content were found in both tolerant and sensitive varieties. The activities of AGPase, SuSy and SPS at flowering were highly positively correlated with yield under the interactive effects of N and waterlogging. These results suggested that the flowering stage is the most important stage that N had the positive regulation on waterlogged rapeseed growth. The carbohydrates translocation from leaves to seeds of the tolerant variety were enhanced after waterlogging, while that of the sensitive variety was still inhibited. This was the main reason for the difference in yield between the two waterlogged varieties.

AbstractIn this study, we investigated the validity of a stealth assessment of physics understanding in an educational game, as well as the effectiveness of different game‐level delivery methods and various in‐game supports on learning. Using a game calledPhysics Playground, we randomly assigned 263 ninth‐ to eleventh‐grade students into four groups: adaptive, linear, free choice and no‐treatment control. Each condition had access to the same in‐game learning supports during gameplay. Results showed that: (a) the stealth assessment estimates of physics understanding were valid—significantly correlating with the external physics test scores; (b) there was no significant effect of game‐level delivery method on students' learning; and (c) physics animations were the most effective (among eight supports tested) in predicting both learning outcome and in‐game performance (e.g. number of game levels solved). We included student enjoyment, gender and ethnicity in our analyses as moderators to further investigate the research questions.
