Multiple commitments and behaviors: a mixed concept approach
Authors: Hoppe Daniel 
Published: May 2017

PurposeThe purpose of this paper is to investigate the interrelationships between different foci of commitment, namely, department commitment (DC) and corporate brand commitment (CBC), and their relationship toward favorable employee behavior on the same level of aggregation.Design/methodology/approachA survey at a maximum care hospital in Germany was conducted (N= 366).FindingsIntegrating two contrasting frameworks (“key mediating concept” and “compatibility concept”) into a mixed model by using the accessibility-diagnosticity framework, support for the predictive nature of DC on CBC was found. Based on the compatibility principle, relationships between DC and department citizenship behavior (DCB) as well as between CBC and brand citizenship behavior (BCB) are empirically supported. Negligible spillover effects were found.Research limitations/implicationsUnderstanding the relationship between DC and CBC shows new ways to strengthen CBC, as the generation of DC has synergetic effects on favorable employee behaviors. DC facilitates employee behavior supporting the department and has an indirect impact on BCB, which is extremely important in service sectors with limited differentiation potential.Originality/valueThis paper provides a new theoretical reasoning to derive relationships between different foci of commitments applicable for future research. Additionally, it is the first implementation of CBC in a multi-foci framework of commitments and favorable employee behaviors. Moreover, it is the first application of the BCB construct in a healthcare context. Finally, empirical support for a mixed concept approach over past models in a multi-foci framework is provided.
To (or not to) label products as artisanal: effect of fashion involvement on customer perceived value
Authors: Bhaduri Gargi , Stanforth Nancy 
Published: May 2017

PurposeThis paper aims to understand whether product descriptor cues related to artisanal qualities can help marketers to delineate their clothing product offerings to consumers by influencing consumers’ perceived product values and the effect (if any) of consumers’ fashion clothing involvement on such value perceptions. In today’s intensely competitive market environment marked by minimal product differentiation, marketers are often using the terms artisan, handcrafted or similar to indicate that their products are different, produced with care, are of higher quality and even premium.Design/methodology/approachFor the study, a 2 (Involvement: High/Low) × 4 (Cues: Control/Artisan-made/Part of a curated collection/Handcrafted) × 2 (products replications: Jeans/Handbags) mixed model repeated measures experiment was designed. A sample of 487 adult female US consumers was recruited using a market-based research firm.FindingsResults indicated that framing luxury products as artisanal using product descriptor cues influenced the perceived value of these products. Moreover, consumers’ fashion involvement positively influenced their perceived value for artisanal luxury products.Originality/valueThe study is one of the few attempts in understanding the value of artisanal luxury products. Given the importance of the artisanal luxury industry to the global economy, focusing on how consumers perceive the value of artisanal luxury products is important to marketers and practitioners as well as academicians. From a theoretical perspective, the study indicates fashion involvement as a predictor of consumers’ perceived value, thereby filling a gap in literature. The study used two different product categories to aid in generalizability of the results.
A review of passive self-sensing tag
Authors: Xu Yawei , Dong Lihong , Wang Haidou , Jing Jiannong , Lu Yongxiang 
Published: May 2017

Purpose
Radio frequency identification tags for passive sensing have attracted wide attention in the area of Internet of Things (IoT). Among them, some tags can sense the property change of objects without an integrated sensor, which is a new trend of passive sensing based on tag. The purpose of this paper is to review recent research on passive self-sensing tags (PSSTs).

Design/methodology/approach
The PSSTs reported in the past decade are classified in terms of sensing mode, composition and the ways of power supply. This paper presents operation principles of PSSTs and analyzes the characteristics of them. Moreover, the paper focuses on summarizing the latest sensing parameters of PSSTs and their matching equipment. Finally, some potential applications and challenges faced by this emerging technique are discussed.

Findings
PSST is suitable for long-term and large-scale monitoring compared to conventional sensors because it gets rid of the limitation of battery and has relatively low cost. Also, the static information of objects stored in different PSSTs can be identified by a single reader without touch.

Originality/value
This paper provides a detailed and timely review of the rapidly growing research in PSST.
Intraspecific variability and reaction norms of forest understorey plant species traits

Published: May 2017

Summary

Trait‐based models of ecological communities typically assume intraspecific variation in functional traits is not important, although such variation can change species trait rankings along gradients in resources and environmental conditions, and thus influence community structure and function.

We examined the degree of intraspecific relative to interspecific variation, and reaction norms of 11 functional traits for 57 forest understorey plant species, including: intrinsic water‐use efficiency (iWUE), Δ15N, five leaf traits, two stem traits and two root traits along gradients in light, nitrogen, moisture and understorey cover.

Our results indicate that interspecific trait variation exceeded intraspecific variation by at least 50% for most, but not all traits. Intraspecific variation in Δ15N, iWUE, leaf nitrogen content (LNC) and root traits was high (47–70%) compared with most leaf traits and stem traits (13–38%).

Δ15N varied primarily along gradients in abiotic conditions, while light and understorey cover were relatively less important. Intrinsic water‐use efficiency was related primarily to light transmission, reflecting increases in photosynthesis relative to stomatal conductance. Leaf traits varied mainly as a function of light availability, with some reaction norms depending on understorey cover. Plant height increased with understorey cover, while stem‐specific density was related primarily to light. Resources, environmental conditions and understorey cover did not contribute strongly to the observed variation in root traits.

Gradients in resources, environmental conditions and competition all appear to control intraspecific variability in most traits to some extent. However, our results suggest that species cross‐over (i.e. trait rank reversals) along the gradients measured here are generally not a concern.

Intraspecific variability in understorey plant species traits can be considerable. However, trait data collected under a narrow range of environmental conditions appears sufficient to establish species rankings and scale between community and ecosystem levels using trait‐based models. Investigators may therefore focus on obtaining a sufficient sample size within a single set of conditions rather than characterizing trait variation across entire gradients to optimize sampling efforts.

Summary

In visually driven seed dispersal mutualisms, natural selection should promote plant strategies that maximize fruit visibility to dispersers. Plants might increase seed dispersal profitability by increasing conspicuousness of fruit display, understood as a plant strategy to maximize fruit detectability by seed dispersers.

The role of different plant traits in fruit choice and consumption by seed dispersers has been broadly studied. However, there is no clear evidence about the importance of the traits that increase conspicuousness of fruit display. Because strategies to maximize conspicuousness of fruit display are diverse, and usually are expected to be costly, we would expect that individual plant species will produce an efficient combination of traits.

We explored this prediction with 62 fleshy fruited plant species of a subtropical Andean forest (Southern Yungas), and using a large dataset of fruit consumption by birds (4476 records). Conspicuousness of fruit display was characterized by both fruit and plant traits including chromatic contrast, size, exposure, aggregation and crop size of fruits. We also considered phylogenetic effects on phenotypic variation.

Fruit consumption was explained by fruit chromatic contrast depending on fruit crop size. These traits revealed low phylogenetic effects, with the exception of four plant clades at different levels in the phylogenetic tree. Negative correlations between pairs of traits support our assumption that fruit display traits are costly, suggesting natural selection favours parsimonious evolutionary pathways.

Plant species seem to rely on conspicuousness of fruit display by a combination of traits that might minimize costs of fruit display. This appears adaptively relevant to improve communication with mutualistic animals, to increase fruit consumption in a community context and, ultimately, to enhance the profitability of seed dispersal.

In Vitro Digestion and Fermentation of Microencapsulated Tributyrin for the Delivery of Butyrate
Authors: Donovan Joseph D. , Bauer Laura , Fahey George C. , Lee Youngsoo 
Published: May 2017

AbstractButyrate possesses negative sensory qualities and is most effectively utilized in the intestine to provide energy to the colonocyte for the maintenance of intestinal health. Butyrate has also shown promise in the treatment of intestinal disorders and diseases such as short bowel syndrome, inflammatory bowel disease, and colon cancer. To modify sensory properties, intestinal release, and butyrate production capabilities, tributyrin (TB) was microencapsulated in whey protein isolate (WPI)‐based and gamma‐cyclodextrin (GC)‐based materials. Using an in vitro digestion and fermentation model, microcapsules containing TB were monitored for their release and production of butyrate in vitro. All samples containing TB showed limited butyrate release (<5%) during oral and gastric stages. In the small intestinal phase, all microcapsules containing TB released approximately 75% of their total butyrate with no significant differences (P > 0.05) across formulations. During the fermentation phase, GC‐based microcapsules produced significantly more butyrate (P < 0.001) on a molar basis than all WPI‐based microcapsules. Butyrate production increased significantly (P < 0.001) over each time interval with GC‐based microcapsules having the highest during the 12 h of fermentation. The GC‐based TB encapsulation systems were able to effectively deliver butyrate to the small intestine and generate butyrate in the large intestine. These microcapsules may, therefore, be beneficial for the maintenance of intestinal health and improvement of disease states across all areas of the gastrointestinal tract.
A general sampling formula for community structure data
Authors: Haegeman Bart , Etienne Rampal S. 
Published: May 2017

Summary

The development of neutral community theory has shown that the assumption of species neutrality, although implausible on the level of individual species, can lead to reasonable predictions on the community level. While Hubbell's neutral model and several of its variants have been analysed in quite some detail, the comparison of theoretical predictions with empirical abundance data is often hindered by technical problems. Only for a few models the exact solution of the stationary abundance distribution is known and sufficiently simple to be applied to data. For other models, approximate solutions have been proposed, but their accuracy is questionable.

Here, we argue that many of these technical problems can be overcome by replacing the assumption of constant community size (the zero‐sum constraint) by the assumption of independent species abundances.

We present a general sampling formula for community abundance data under this assumption. We show that for the few models for which an exact solution with zero‐sum constraint is known, our independent species approach leads to very similar parameter estimates as the zero‐sum models, for six frequently studied tropical forest community samples.

We show that our general sampling formula can be easily confronted to a much wider range of datasets (very large datasets, relative abundance data, presence‐absence data, and sets of multiple samples) for a large class of models, including non‐neutral ones. We provide an R package, called SADISA (Species Abundance Distributions under the Independent Species Assumption), to facilitate the use of the sampling formula.
Bystander Cardiopulmonary Resuscitation Is Clustered and Associated With Neighborhood Socioeconomic Characteristics: A Geospatial Analysis of Kent County, Michigan

AbstractObjectivesGeographic clustering of bystander cardiopulmonary resuscitation (CPR) is associated with demographic and socioeconomic features of the community where out‐of‐hospital cardiac arrest (OHCA) occurred, although this association remains largely untested in rural areas. With a significant rural component and relative racial homogeneity, Kent County, Michigan, provides a unique setting to externally validate or identify new community features associated with bystander CPR. Using a large, countywide data set, we tested for geographic clustering of bystander CPR and its associations with community socioeconomic features.MethodsSecondary analysis of adult OHCA subjects (2010–2015) in the Cardiac Arrest Registry to Enhance Survival (CARES) data set for Kent County, Michigan. After linking geocoded OHCA cases to U.S. census data, we used Moran's I‐test to assess for spatial autocorrelation of population‐weighted cardiac arrest rate by census block group. Getis‐Ord Gi statistic assessed for spatial clustering of bystander CPR and mixed‐effects hierarchical logistic regression estimated adjusted associations between community features and bystander CPR.ResultsOf 1,592 subjects, 1,465 met inclusion criteria. Geospatial analysis revealed significant clustering of OHCA in more populated/urban areas. Conversely, bystander CPR was less likely in these areas (99% confidence) and more likely in suburban and rural areas (99% confidence). Adjusting for clinical, demographic, and socioeconomic covariates, bystander CPR was associated with public location (odds ratio [OR] = 1.19; 95% confidence interval [CI] = 1.03–1.39), initially shockable rhythms (OR = 1.48; 95% CI = 1.12–1.96), and those in urban neighborhoods (OR = 0.54; 95% CI = 0.38–0.77).ConclusionsOut‐of‐hospital cardiac arrest and bystander CPR are geographically clustered in Kent County, Michigan, but bystander CPR is inversely associated with urban designation. These results offer new insight into bystander CPR patterns in mixed urban and rural regions and afford the opportunity for targeted community CPR education in areas of low bystander CPR prevalence.
Determinants of Blood Brain‐Derived Neurotrophic Factor Blood Levels in Patients with Alcohol Use Disorder

Published: May 2017

BackgroundBlood brain‐derived neurotrophic factor (BDNF) levels are influenced by both addiction and mood disorders, as well as somatic conditions, gender, and genetic polymorphisms, leading to widely varying results. Depressive symptoms and episodes are frequently observed in patients with alcohol use disorder, and vary widely over time, making it a challenge to determine which aspects are specifically involved in variations of serum BDNF levels in this population.MethodsWe assessed 227 patients with alcohol dependence involved in a detoxification program, at baseline and after a follow‐up of 6 months, for the Alcohol Use Disorders Identification Test score, the length of alcohol dependence, and the number of past detoxification programs. The Beck Depression Inventory and information on current tobacco and alcohol use, suicidal ideation, body mass index, age, gender, and psychotropic treatments were also collected. Serum BDNF (ELISA) and 2 genetic polymorphisms of the BDNF gene (Val33Met and rs962369) were analyzed.ResultsThe presence of the Met allele, 2 markers of the history of alcohol dependence (gamma glutamyl transferase and the number of past treatments in detoxification programs), and the presence of a depressive episode (but not depressive score) were significantly associated with the 2 blood levels of BDNF at baseline and after 6 months. After controlling for baseline BDNF levels, the presence of the Met allele and an ongoing depressive episode were the only variables associated with changes in BNDF levels after 6 months.ConclusionsLow serum BDNF levels are associated with characteristics related to alcohol consumption and mood disorders, and variants of the BDNF gene in alcohol use disorder patients. The factors that most strongly influenced changes in serum BDNF levels following treatment in an alcohol detoxification program were variants of the BDNF gene and ongoing depression.

Published: May 2017

SummaryContemporary data are lacking for procedural practice, training provision and outcomes for awake fibreoptic intubation in the UK. We performed a prospective cohort study of awake fibreoptic intubations at a tertiary centre to assess current practice. Data from 600 elective or emergency awake fibreoptic intubations were collected to include information on patient and operator demographics, technical performance and complications. This comprised 1.71% of patients presenting for surgery requiring a general anaesthetic, with the majority occurring in patients presenting for head and neck surgery. The most common indication was reduced mouth opening (26.8%), followed by previous airway surgery or head and neck radiotherapy (22.5% each). Only five awake fibreoptic intubations were performed with no sedation, but the most common sedative technique was combined target‐controlled infusions of remifentanil and propofol. Oxygenation was achieved with high‐flow, heated and humidified oxygen via nasal cannula in 49.0% of patients. Most operators had performed awake fibreoptic intubation more than 20 times previously, but trainees were the primary operator in 78.6% of awake fibreoptic intubations, of which 86.8% were directly supervised by a consultant. The failure rate was 1.0%, and 11.0% of awake fibreoptic intubations were complicated, most commonly by multiple attempts (4.2%), over‐sedation (2.2%) or desaturation (1.5%). The only significant association with complications was the number of previous awake fibreoptic intubations performed, with fewer complications occurring in the hands of operators with more awake fibreoptic intubation experience. Our data demonstrate that awake fibreoptic intubation is a safe procedure with a high success rate. Institutional awake fibreoptic intubation training can both develop and maintain trainee competence in performing awake fibreoptic intubation, with a similar incidence of complications and success compared with consultants.

SummarySome short procedures require deep neuromuscular blockade, which needs to be reversed at the end of the procedure. Forty‐four patients undergoing elective laryngeal micro‐surgery were randomly allocated into two groups: rocuronium 0.45 mg.kg−1 with neostigmine (50 μg.kg−1 with glycopyrrolate 10 μg.kg−1) reversal (moderate block group) vs. rocuronium 0.90 mg.kg−1 with sugammadex (4 mg.kg−1) reversal (deep block group). The primary outcome was the intubating conditions during laryngoscopy secondary outcomes included recovery of neuromuscular block; conditions for tracheal intubation; satisfaction score as determined by the surgeon; onset of neuromuscular block; and postoperative sore throat. The onset of neuromuscular block was more rapid, and intubation conditions and ease of intra‐operative laryngoscopy were more favourable, and the satisfaction score was lower in the moderate block group compared with the deep block group. No difference was found in the incidence of postoperative sore throat. In laryngeal micro‐surgery, the use of rocuronium 0.9 mg.kg−1 with sugammadex for reversal was associated with better surgical conditions and a shorter recovery time than rocuronium 0.45 mg.kg−1 with neostigmine.
