A consumption timecycle: contextually situated and temporally recurring experiences
Authors: Ryynänen Toni , Heinonen Visa 
Published: August 2020

Purpose
Temporal consumption experiences have been conceptualised as universal, subjective or practice-based experiences. Little research, though, addresses such experiences in conjunction with the repeated and situational consumption events that bring them about. The purpose of this paper is to extend current knowledge by examining how the temporal and situational intertwine during consumption events. For this purpose, the concept of a consumption timecycle based on the research data is constructed.

Design/methodology/approach
The paper takes a longitudinal and researcher-led approach to study temporal consumption experiences. The data was collected through participant observations, video recordings and personal subjective introspections during three consecutive annual Nordic motorcycle consumer trade shows (2014–2016). The data was analysed using an interpretive approach.

Findings
The results demonstrate five temporalities that characterise a consumption timecycle as follows: emerging, core, intensifying, fading and idle-time temporalities. The features of these temporal experiences are presented in the conclusions section of the paper.

Research limitations/implications
Recalled temporal experiences are mediated experiences and they differ from lived experiences. The transferability or generalisability of the results might be limited, as the case is situated in the Nordic context.

Originality/value
The paper presents the novel concept of a consumption timecycle that extends current debates about consumer time. The consumption timecycle is contrasted with established temporal concepts in consumer and marketing research.

Published: August 2020

AbstractIntroductionLife review writing can be used to improve depressive symptoms in well older adults, but it is unclear whether the reminiscing, writing, or socialising is associated with the improvements. This study assessed the feasibility of a controlled trial comparing life review writing with two active control groups designed to isolate the acts of (a) engaging in a meaningful leisure activity and (b) socialising.MethodsTwenty‐four participants from a 100‐bed assisted living facility were enrolled in the study. Participants ranged in age from 70 to 98 years (M = 83.9, SD = 7.6). Eight 1‐hour weekly sessions were held, with participants assigned to one of three groups: (a) life review writing, (b) painting, or (c) coffee from around the world. At baseline, participants completed a demographic and health questionnaire, the Mini‐Cog, and the Geriatric Depression Scale Short Form (GDS‐15). The GDS‐15 was administered again at weeks 4 and 8, along with the health questionnaire at post‐test.ResultsNearly 25% (N = 24) of the facility's residents attended at least one session, with an average attendance rate of 66.4%, or 5.3 sessions. However, to achieve this participation rate, our original plan to employ random assignment had to be abandoned. The groups were a partial success insofar as we successfully isolated engaging in a meaningful activity in the painting group, but the writing group engaged in less reminiscing than hoped. At post‐test, seven participants reported health, mood, and social life benefits. GDS‐15 scores fluctuated over time, with no significant improvement from pre‐ to post‐test.ConclusionThe residents’ low willingness to be randomised creates a serious selection bias, but randomising volunteers into different activities runs counter to client‐centred therapy. To scrutinise the mechanisms of change of life review writing, we recommend comparing two writing groups: one that reminisces and one that does not.
Role of soy lecithin on emulsion stability of dairy beverages treated by ultrasound
Authors: Nyuydze Collette , Martínez‐Monteagudo Sergio I 
Published: August 2020

The objective of this work was to evaluate the impact of soy lecithin during the formation and stability of oil‐in‐water ultrasound emulsions. Pre‐emulsions formulated with either 0%, 0.025% and 0.05% of soy lecithin were sonicated at different acoustic intensities (42–70 W/cm2) for 5 min. Dynamic rheology showed an improved stability of the ultrasound emulsions at high acoustic intensity and without soy lecithin, displaying a distinctive viscoelastic region and a behaviour of weak gel. During 21 days of storage at 4°C, the particle size slightly increased (470–500 nm), while the mechanical spectra remained unchanged. The outcomes of this investigation suggest that ultrasound can be used as manufacturing aid for the formulation of dairy‐based emulsions.

Abstract

Forecasting the responses of biodiversity to global change has never been more important. However, many ecologists faced with limited sample sizes and shoestring budgets often resort to extrapolating predictive models beyond the range of their data to support management actions in data‐deficient contexts. This can lead to error‐prone inference that has the potential to misdirect conservation interventions and undermine decision‐making. Despite the perils associated with extrapolation, little guidance exists on the best way to identify it when it occurs, leaving users questioning how much credence they should place in model outputs. To address this, we present dsmextra, a new R package for measuring, summarizing and visualizing extrapolation in multivariate environmental space.

dsmextra automates the process of conducting quantitative, spatially explicit assessments of extrapolation on the basis of two established metrics: the Extrapolation Detection (ExDet) tool and the percentage of data nearby (%N). The package provides user‐friendly functions to (a) calculate these metrics, (b) create tabular and graphical summaries, (c) explore combinations of covariate sets as a means of informing covariate selection and (d) produce visual displays in the form of interactive html maps.

dsmextra implements a model‐agnostic approach to extrapolation detection that is applicable across taxonomic groups, modelling techniques and datasets. We present a case study fitting a density surface model to visual detections of pantropical spotted dolphins Stenella attenuata in the Gulf of Mexico.

Predictive modelling seeks to deliver actionable information about the states and trajectories of ecological systems, yet model performance can be strongly impaired out of sample. By assessing conditions under which models are likely to fail or succeed in extrapolating, ecologists may gain a better understanding of biological patterns and their underlying drivers. Critical to this is a concerted effort to standardize best practice in model evaluation, with an emphasis on extrapolative capacity.

Published: August 2020

AbstractHeterogeneity is a hallmark of cancer. For various cancer outcomes/phenotypes, supervised heterogeneity analysis has been conducted, leading to a deeper understanding of disease biology and customized clinical decisions. In the literature, such analysis has been oftentimes based on demographic, clinical, and omics measurements. Recent studies have shown that high‐dimensional histopathological imaging features contain valuable information on cancer outcomes. However, comparatively, heterogeneity analysis based on imaging features has been very limited. In this article, we conduct supervised cancer heterogeneity analysis using histopathological imaging features. The penalized fusion technique, which has notable advantages—such as greater flexibility—over the finite mixture modeling and other techniques, is adopted. A sparse penalization is further imposed to accommodate high dimensionality and select relevant imaging features. To improve computational feasibility and generate more reliable estimation, we employ model averaging. Computational and statistical properties of the proposed approach are carefully investigated. Simulation demonstrates its favorable performance. The analysis of The Cancer Genome Atlas (TCGA) data may provide a new way of defining/examining breast cancer heterogeneity.

ZusammenfassungHintergrund2018 wurde ein Update der 2013 erstmalig publizierten S3‐Leitlinie für die „Diagnostik, Therapie und Nachsorge des Melanoms“ im Rahmen des Leitlinienprogramms Onkologie (OL) mit einer Aktualisierung der bestehenden leitlinienbasierten Qualitätsindikatoren (QI) veröffentlicht.Patienten und MethodikEine multidisziplinäre und interprofessionelle Arbeitsgruppe überarbeitete die leitlinienbasierten Qualitätsindikatoren auf Basis der neuen, starken Empfehlungen (Empfehlungsgrad A) des Leitlinien‐Updates, einer systematischen Recherche internationaler Indikatoren und den Ergebnissen der Qualitätsindikatoren aus zertifizierten Hautkrebszentren nach einem standardisierten, mehrstufigen Prozess.ErgebnisseAusgehend von ursprünglich zwölf leitlinienbasierten Qualitätsindikatoren aus dem Jahre 2013 wurde 2018 ein aktualisiertes Set mit neun Indikatoren verabschiedet. Vier Qualitätsindikatoren wurden unverändert beibehalten, zwei modifiziert, zwei gestrichen und drei neue ergänzt. Im Gegensatz zur Primärentwicklung konnten bei der Aktualisierung Ergebnisse von den in Hautkrebszentren implementierten Qualitätsindikatoren berücksichtigt werden.SchlussfolgerungenLeitlinienbasierte Qualitätsindikatoren können in der Onkologie durch die enge Zusammenarbeit zwischen Leitliniengruppe und Zertifizierungskommission implementiert werden. Die gemessenen Ergebnisse bilden die Basis für die Aktualisierung sowohl der Leitlinie als auch des QI‐Prozesses und geben Auskunft über die Versorgungsrealität, die Leitlinienadhärenz, aber auch über die Implementierbarkeit der Qualitätsindikatoren selbst. Dieser Prozess kann transparent dargestellt werden, ist dynamisch und muss daher regelhaft aktualisiert werden.
Systemische Immunsuppression in Zeiten von COVID‐19: Müssen wir umdenken?
Authors: Grabbe Stephan , Beissert Stefan , Enk Alexander 
Published: August 2020

ZusammenfassungDie aktuelle SARS‐CoV‐2 Pandemie gefährdet vor allem ältere Menschen mit kardiopulmonalen und metabolischen Vorerkrankungen. In aktueller Diskussion ist jedoch auch, ob Patienten unter immunsuppressiver Therapie ebenfalls ein höheres Risiko haben, im Fall einer COVID‐19‐Erkrankung einen schweren Krankheitsverlauf zu erleiden. Grundsätzlich gibt es derzeit jedoch keine Datenlage für eine generelle Reduktion oder Pausierung einer Immunsuppression bei Patienten mit Autoimmunerkrankungen in Zeiten der SARS‐CoV‐2‐Pandemie. Da es jedoch derzeit weder eine wirksame Therapie, noch einen entsprechenden Impfschutz gibt, sollten wir uns gezielt mit der Problematik chronisch‐immunsupprimierter Patienten beschäftigen. Um Risiken für Patienten zu minimieren, sollte die Indikation für eine solche Therapie mit besonderer Sorgfalt gestellt werden. Insbesondere sollten Immuntherapeutika, die langfristige Effekte erzeugen (zum Beispiel Rituximab) mit besonderer Vorsicht eingesetzt werden. Demgegenüber könnten immunmodulierende Substanzen, die keine Immunsuppression induzieren (zum Beispiel systemische Immunglobuline, Doxycyclin) oder die intrinsische Wirkungen auf SARS‐CoV‐2 haben (Calcineurininhibitoren, Chloroquin, Hydroxychloroquin), eine sinnvolle Alternative darstellen.

ZusammenfassungDie durch das Coronavirus SARS‐CoV‐2 verursachte Krankheit COVID‐19 hat sich zu einer Pandemie entwickelt. Bei der Betrachtung von dermatologischen und allergologischen Krankheiten, die potenziell von COVID‐19 betroffen sind, stehen wir vor komplexen Herausforderungen, die Pathogenese und Beeinflussung verschiedener immunologischer Signalwege einschließen. Medizinische Behandlungen müssen daher im Zusammenhang mit dieser Infektion oft neu bewertet und in Frage gestellt werden.Dieser Übersichtsartikel fasst den aktuellen Wissensstand zu COVID‐19 hinsichtlich der wichtigsten dermatologischen und allergologischen Erkrankungen zusammen. Es werden aber auch die medizinischen Bereiche beschrieben, für die keine ausreichenden Daten vorliegen. Unter Zusammenfassung der publizierten Daten und grundsätzlicher pathophysiologischer Überlegungen werden hier Schlussfolgerungen für das Management unserer Patienten während der Pandemie gezogen. Wir konzentrieren uns auf häufige Hauterkrankungen mit komplexer immunologischer Pathogenese: Psoriasis, Ekzeme einschließlich atopischer Dermatitis, Typ‐I‐Allergien, blasenbildende Autoimmundermatosen, Kollagenosen, Vaskulitiden und Hautkrebserkrankung. Da viele weitere Hauterkrankungen verwandte oder vergleichbare immunologische Reaktionsmuster aufweisen, können pathophysiologisch ähnliche entzündliche Dermatosen möglicherweise auch mit ähnlichen therapeutischen Überlegungen und Schlussfolgerungen während der Pandemie behandelt werden. Daher soll diese Übersicht Behandlungsempfehlungen auf der Basis bisher publizierter Daten und Empfehlungen zu Therapieentscheidungen auch über die hier diskutierten, häufigsten Erkrankungen hinaus liefern.
Post‐socialist constitutions: The de jure–de facto gap, its effects and determinantsa
Authors: Metelska‐Szaniawska Katarzyna 
Published: August 2020

AbstractThe aim of this paper is to contribute to the debate on constitutional rules and their economic effects by extending focus to the de jure–de facto constitutional gap. First, evidence is provided that size of this gap matters as higher gaps lower the effectiveness of the constitutional commitment mechanism. Second, several explanations of this gap are identified, in particular relating to the democratization process, political conflict, age and comprehensiveness of the constitution. The conclusions are based on an empirical study for the unique setting of the post‐socialist countries of Europe and Asia, which all enacted new constitutional frameworks after 1989 and it is shown that in some of these countries constitutions acted as blueprints.
Inter‐observer variability of two grading systems for equine glandular gastric disease
Authors: Tallon Rose , Hewetson Michael 
Published: August 2020

AbstractBackgroundEquine glandular gastric disease (EGGD) is recognised as a separate entity to equine squamous gastric disease (ESGD) and it is recommended that lesions are graded differently. Currently, no validated scoring system exists for EGGD.ObjectivesTo determine inter‐observer reliability of two previously described grading systems for EGGD and to assess if agreement improved with gastroscopy experience, specialist training or familiarity with the descriptive system.Study designCross‐sectional survey.MethodsA link to an electronic questionnaire containing 20 images of glandular lesions was circulated. Respondents were asked to score lesions using descriptive terminology and a 0‐2 verbal rating scale (VRS). Krippendorff's alpha reliability estimate was used to assess inter‐rater agreement. A mixed effects model was used to determine which descriptive categories were associated with lesions being described as severe and decision to treat.ResultsEighty‐two veterinarians responded, 49 diplomates and 33 non‐diplomates. There was no agreement when all four descriptive variables were combined (α = 0.19). Agreement was fair to moderate for severity (α = 0.52), distribution (α = 0.44), appearance (α = 0.38) and shape (α = 0.32). Agreement for the VRS was similar to that for severity (α = 0.53). Agreement was better among diplomates across all categories. Lesion appearance and shape, but not distribution, were associated with both a decision to treat; and lesions being described as severe (P =< .05). A VRS score 2/2 was associated with a lesion being described as severe (OR 75.2, 95% CI 51.12‐110.48, P =< .001).Main limitationsIntra‐observer variability was not assessed. The number of images is relatively small, and the decision to treat is based on several factors in practice.ConclusionsOverall, agreement for the descriptive system was poor. Better delineation of descriptive category boundaries and characteristics should be determined. Agreement was similar when comparing the severity category and the VRS. Extrapolation to a VRS based on lesion severity may therefore be possible.

Published: August 2020

AimThe present study aimed to examine the prevalence of dual sensory impairment, and to identify its risk factors among community‐dwelling older adults in Selangor.MethodsSecondary analysis was carried out on data collected by the Grand Challenge Project among older adults aged ≥65 years from Selangor. Data on sociodemographic information, medical history, cognitive function and functional performance were obtained through face‐to‐face interviews using standardized questionnaires. Visual acuity was measured using the Early Treatment Diabetic Retinopathy Study (ETDRS) chart while hearing was assessed using pure‐tone audiometry. Descriptive analysis was used to measure the prevalence of the impairments, and logistic regression analysis was used to identify the risk factors.ResultsThe prevalence of dual sensory impairment and hearing impairment were at 10.5% and 76.2% respectively. Multivariate logistic regression analysis revealed that participants with lower cognitive scores were associated with dual sensory impairment (odds ratio, 0.90; 95% confidence interval, 0.83–0.98), while smoking was found associated with hearing impairment (odds ratio, 6.58; 95% confidence interval, 1.51–28.65).ConclusionDual sensory impairment is common among older adults in Selangor. The association between dual sensory impairment and cognitive function suggests the need to have visual and hearing screening on older adults for early detection particularly those at risk of cognitive impairment. The prevalence of hearing impairment was reported high among older adults and smokers appeared to be at higher risk of the impairment. Geriatr Gerontol Int 2020; 20: 911–916.

SummaryBackgroundHealth Care Professionals struggle to initiate conversations about overweight in toddlerhood. A novel 3D body size scale (3D BSS) may facilitate engagement with this topic during pediatric appointments.ObjectivesTo explore barriers and facilitators to using the 3D BSS through a mixed‐methods design.MethodsFor the qualitative phase, parents of toddlers (n = 38) participated in semi‐structured interviews introducing the 3D BSS of 4–5‐year‐old children. For the quantitative phase, pre‐ and post‐interview questionnaires were administered to ascertain the acceptability of the 3D BSS.ResultsParents rated the 3D BSS as “very” (n = 20, 52.6%) to “moderately” (n = 12, 31.6%) acceptable. Thematic analysis revealed four barriers to acceptability: i) the sensitive nature of child weight, ii) the belief that weight does not determine health, iii) the visual normalisation of overweight and iv) the need to account for individual variation in growth patterns. However, these barriers could be overcome through three facilitators: i) the provision of expert guidance ii) the value of simple tools, and iii) tailoring conversations to familial needs.ConclusionsParents considered the 3D BSS an acceptable visual resource to discuss child weight during routine appointments. However, the acceptability of the tool was conditional on a sensitive, collaborative, and tailored delivery approach.
On Some Characteristics of Gaussian Covariance Functions
Authors: De Iaco Sandra , Posa Donato , Cappello Claudia , Maggio Sabrina 
Published: August 2020

SummaryThe concepts of isotropy/anisotropy and separability/non‐separability of a covariance function are strictly related. If a covariance function is separable, it cannot be isotropic or geometrically anisotropic, except for the Gaussian covariance function, which is the only model both separable and isotropic. In this paper, some interesting results concerning the Gaussian covariance model and its properties related to isotropy and separability are given, and moreover, some examples are provided. Finally, a discussion on asymmetric models, with Gaussian marginals, is furnished and the strictly positive definiteness condition is discussed.
