Can advanced technology affect customer-based brand equity in service firms? An empirical study in upscale hotels
Authors: Šeric Maja , Gil-Saura Irene , Mollá-Descals Alejandro 
Published: December 2015

Purpose– The purpose of this paper is to empirically test the impact of perceived information and communication technology (ICT) on creation of brand equity within service firms, more specifically upscale hotels. The relationships between ICT and three brand equity dimensions, i.e. brand image, perceived quality, and brand loyalty are examined.Design/methodology/approach– The empirical research was conducted in 20 upscale hotels in Rome-Italy, collecting data from 335 guests.Findings– Advanced ICT directly influences perceived quality and image, while the impact of ICT on loyalty is mediated by perceived quality. Additionally, positive and significant relationships are found between the three brand equity dimensions.Research limitations/implications– The lack of significance of ICT impact on loyalty needs further attention. Future studies could center on this specific relationship, examining whether hotel companies that implement technology efficiently are able to deal with loyalty.Practical implications– Managers are encouraged to invest in advanced technologies as their adoption and subsequent perception among guests can shape brand image and perceived service quality, thus influencing brand equity from the consumer perspective.Originality/value– The contributions of this paper are fourfold. First, the ICT and customer-based brand equity concepts are studied together in the hotel context. Second, the inter-relationship among the three brand equity dimensions is analyzed. Third, the model is tested from the guest perceptive, as customers themselves can provide the most valuable inputs for business strategies. Finally, the work contributes to the service field by providing an empirical evidence on the potential and impact of advanced technology.
COMAT: core ontology of matter
Authors: Madalli Devika , Sulochana Anila , Singh Abhinav Kumar 
Published: December 2015

Purpose
– Matter is an important topic of science as a discipline since its inception. Nevertheless, along with the evolution of semantic web, matter has got equal importance among the ontology developers. The current work describes an ontology of matter that the authors developed in the lab. The purpose of this paper is to come up with an exhaustive list of concepts and relations to cover matter domain under one umbrella, after identifying the gaps in the present ontologies.

Design/methodology/approach
– Ontology was developed following faceted analytico-synthetic approach of knowledge organization. The authors followed hybrid developmental approach which includes top-down as well as bottom-up development strategy, for creating classes and subclasses. The authors modelled matter domain comprehensively considering different aspects of matter. The theories behind the modelling approach helps to maintain the consistency of further extensions.

Findings
– Final ontology has around 280 concepts and as many as 60 properties which include both object property and datatype property.

Research limitations/implications
– There exists very vague definition of concepts in different subject areas, as matter is a domain of study in physics, chemistry, material science, metallurgy, etc. Same material has been adopted differently depending upon purpose of its study/use in that field. For example aspirin is simply a chemical compound in chemistry, whereas in medicine it is also an agent.

Practical implications
– Present work claims to influence the ontology engineers to develop more extension to this core ontology of matter (COMAT). Also this will find its use in information retrieval, semantic annotations and in several other semantic knowledge-based systems.

Originality/value
– COMAT is the most recent work of the domain. Originality lies in the way matter domain has been looked up, from a very wide perspective, as well as in the approach of modelling the domain.
Performance and accuracy analysis of semantic kernel functions
Authors: Manuja Manoj , Garg Deepak 
Published: December 2015

Purpose
– Syntax-based text classification (TC) mechanisms have been overtly replaced by semantic-based systems in recent years. Semantic-based TC systems are particularly useful in those scenarios where similarity among documents is computed considering semantic relationships among their terms. Kernel functions have received major attention because of the unprecedented popularity of SVMs in the field of TC. Most of the kernel functions exploit syntactic structures of the text, but quite a few also use a priori semantic information for knowledge extraction. The purpose of this paper is to investigate semantic kernel functions in the context of TC.

Design/methodology/approach
– This work presents performance and accuracy analysis of seven semantic kernel functions (Semantic Smoothing Kernel, Latent Semantic Kernel, Semantic WordNet-based Kernel, Semantic Smoothing Kernel having Implicit Superconcept Expansions, Compactness-based Disambiguation Kernel Function, Omiotis-based S-VSM semantic kernel function and Top-k S-VSM semantic kernel) being implemented with SVM as kernel method. All seven semantic kernels are implemented in SVM-Light tool.

Findings
– Performance and accuracy parameters of seven semantic kernel functions have been evaluated and compared. The experimental results show that Top-k S-VSM semantic kernel has the highest performance and accuracy among all the evaluated kernel functions which make it a preferred building block for kernel methods for TC and retrieval.

Research limitations/implications
– A combination of semantic kernel function with syntactic kernel function needs to be investigated as there is a scope of further improvement in terms of accuracy and performance in all the seven semantic kernel functions.

Practical implications
– This research provides an insight into TC using a priori semantic knowledge. Three commonly used data sets are being exploited. It will be quite interesting to explore these kernel functions on live web data which may test their actual utility in real business scenarios.

Originality/value
– Comparison of performance and accuracy parameters is the novel point of this research paper. To the best of the authors’ knowledge, this type of comparison has not been done previously.
Integrated population modelling reveals a perceived source to be a cryptic sink

Published: December 2015

SummaryDemographic links among fragmented populations are commonly studied as source‐sink dynamics, whereby source populations exhibit net recruitment and net emigration, while sinks suffer net mortality but enjoy net immigration. It is commonly assumed that large, persistent aggregations of individuals must be sources, but this ignores the possibility that they are sinks instead, buoyed demographically by immigration.We tested this assumption using Bayesian integrated population modelling ofGreenland white‐fronted geese (Anser albifrons flavirostris) at their largest wintering site (Wexford,Ireland), combining capture–mark–recapture, census and recruitment data collected from 1982 to 2010. Management for this subspecies occurs largely on wintering areas; thus, study of source‐sink dynamics of discrete regular wintering units provides unprecedented insights into population regulation and enables identification of likely processes influencing population dynamics atWexford and among 70 otherGreenland white‐fronted goose wintering subpopulations.Using results from integrated population modelling, we parameterized an age‐structured population projection matrix to determine the contribution of movement rates (emigration and immigration), recruitment and mortality to the dynamics of the Wexford subpopulation.Survival estimates for juvenile and adult birds at Wexford and adult birds elsewhere fluctuated over the 29‐year study period, but were not identifiably different. However, per capita recruitment rates at Wexford in later years (post‐1995) were identifiably lower than in earlier years (pre‐1995). The observed persistence of theWexford subpopulation was only possible with high rates of immigration, which exceeded emigration in each year. Thus, despite its apparent stability,Wexford has functioned as a sink over the entire study period.These results demonstrate that even large subpopulations can potentially be sinks, and that movement dynamics (e.g. immigration) among winters can dramatically obscure key processes driving subpopulation size. Further, novel population models which integrate capture–mark–recapture, census and recruitment data are essential to correctly ascribing source‐sink status and accurately informing development of site‐safeguard networks.
Interannual variation and long‐term trends in proportions of resident individuals in partially migratory birds

Published: December 2015

SummaryPartial migration – a part of a population migrates and another part stays resident year‐round on the breeding site – is probably the most common type of migration in the animal kingdom, yet it has only lately garnered more attention. Theoretical studies indicate that in partially migratory populations, the proportion of resident individuals (PoR) should increase in high latitudes in response to the warming climate, but empirical evidence exists for few species.We provide the first comprehensive overview of the environmental factors affecting PoR and the long‐term trends in PoR by studying 27 common partially migratory bird species in Finland.The annual PoR values were calculated by dividing the winter bird abundance by the preceding breeding abundance. First, we analysed whether early‐winter temperature, winter temperature year before or the abundance of tree seeds just before overwintering explains the interannual variation in PoR. Secondly, we analysed the trends in PoR between 1987 and 2011.Early‐winter temperature explained the interannual variation in PoR in the waterbirds (waterfowl and gulls), most likely because the temperature affects the ice conditions and thereby the feeding opportunities for the waterbirds. In terrestrial species, the abundance of seeds was the best explanatory variable. Previous winter's temperature did not explain PoR in any species, and thus, we conclude that the variation in food availability caused the interannual variation in PoR. During the study period, PoR increased in waterbirds, but did not change in terrestrial birds.Partially migratory species living in physically contrasting habitats can differ in their annual and long‐term population‐level behavioural responses to warming climate, possibly because warm winter temperatures reduce ice cover and improve the feeding possibilities of waterbirds but do not directly regulate the food availability for terrestrial birds.

Published: December 2015

ObjectiveTo synthesize new findings from the THRIVE Research Collaborative (The Research Initiative Valuing Eldercare) related to the Green House (GH) model of nursing home care and broadly consider their implications.Data SourcesInterviews and observations conducted in GH and comparison homes, Minimum Data Set (MDS) assessments, Medicare data, and Online Survey, Certification and Reporting data.Study DesignCritical integration and interpretation of findings based on primary data collected 2011–2014 in 28 GH homes (from 16 organizations), and 15 comparison nursing home units (from 8 organizations); and secondary data derived from 2005 to 2010 for 72 GH homes (from 15 organizations) and 223 comparison homes.Principal FindingsImplementation of the GH model is inconsistent, sometimes differing from design. Among residents of GH homes, adoption lowers hospital readmissions, three MDS measures of poor quality, and Part A/hospice Medicare expenditures. Some evidence suggests the model is associated with lower direct care staff turnover.ConclusionsRecommendations relate to assessing fidelity, monitoring quality, capitalizing opportunities to improve care, incorporating evidence‐based practices, including primary care providers, supporting high‐performance workforce practices, aligning Medicare financial incentives, promoting equity, informing broad culture change, and conducting future research.
Evidence of ameliorated Middle Weichselian climate and sub‐arctic environment in the western Baltic region: coring lake sediments at Klintholm, Møn, Denmark
Authors: Houmark‐Nielsen Michael , Bennike Ole , Lemdahl Geoffrey , Lüthgens Christopher 
Published: December 2015

Coring through glaciotectonically stacked Quaternary sediments situated below sea level on the island of Møn, Denmark, recovered a succession of interstadial sediments of Middle Weichselian age. Plant and animal remains including insects found in laminated sand and mud indicate deposition in a lake surrounded by dwarf shrubs, herbs, mosses and rare trees. The insect fauna indicates a mean July temperature of 8–12 °C, suggesting an arctic to sub‐arctic environment, while winter temperatures around −8 to −22 °C suggest periglacial conditions with permafrost. Luminescence dating of sediment samples gave ages from 48–29 ka, and radiocarbon dating indicates deposition of plant fragments between 45 and 36 kaBP. The fossil assemblage from Møn shows close resemblance to those from other sites with similar ages found in the vicinity of the western Baltic Basin.

AbstractHomeobox genes play important roles in craniofacial morphogenesis. However, the characteristics of the transcription factor Hoxc during palate formation remain unclear. We examined the immunolocalization patterns of Hoxc5, Hoxc4, and Hoxc6 in palatogenesis of cleft palate (Eh/Eh) mice. On the other hand, mutations in the FGF/FGFR pathway are exclusively associated with syndromic forms of cleft palate. We also examined the immunolocalization of Fgfr1 and Erk1/2 to clarify their relationships with Hoxc in palatogenesis. Some palatal epithelial cells showed Hoxc5 labeling, while almost no labeling of mesenchymal cells was observed in +/+ mice. As palate formation progressed in +/+ mice, Hoxc5, Hoxc4, and Hoxc6 were observed in medial epithelial seam cells. Hoxc5 and Hoxc6 were detected in the oral epithelium. The palatal mesenchyme also showed intense staining for Fgfr1 and Erk1/2 with progression of palate formation. In contrast, the palatal shelves of Eh/Eh mice exhibited impaired horizontal growth and failed to fuse, resulting in a cleft. Hoxc5 was observed in a few epithelial cells and diffusely in the mesenchyme of Eh/Eh palatal shelves. No or little labeling of Fgfr1 and Erk1/2 was detected in the cleft palate of Eh/Eh mice. These findings suggest that Hoxc genes are involved in palatogenesis. Furthermore, there may be the differences in the localization pattern between Hoxc5, Hoxc4, and Hoxc6. Additionally, Hoxc distribution in palatal cells during palate development may be correlated with FGF signaling. (228/250 words) © 2016 Japanese Teratology Society
Do patient characteristics influence efficacy and renal outcomes in liver transplant patients receiving everolimus?

Published: December 2015

AbstractData from the 24‐month randomized, multicenter, open‐label H2304 study in 719 de novo liver transplant recipients were analyzed to evaluate the influence of variables potentially affecting immunological or renal response: recipient age, gender, end‐stage disease, hepatitis C virus (HCV) status, and Model for End‐stage Liver Disease score and estimated glomerular filtration rate (eGFR) at randomization (day 30). Treated BPAR was similar between everolimus with reduced tacrolimus (EVR + Reduced TAC) vs. conventional tacrolimus‐based therapy (TAC Control) in all subpopulations, with a trend to lower risk under everolimus with reduced tacrolimus (EVR + Reduced TAC) in patients <60 yrs and HCV‐negative recipients. Risk of graft loss or death was similar in both treatment groups for all subpopulations. The change in eGFR to month 24 showed a benefit for EVR + Reduced TAC vs. TAC Control in all subpopulations other than those with the lowest baseline eGFR (30 to <55 mL/min/1.73m2), with a significant difference in favor of EVR + Reduced TAC for younger recipients (<60 yr), female patients, HCV‐negative patients and those with baseline eGFR of 55 to <70 mL/min/1.73 m2. Everolimus with reduced tacrolimus maintains efficacy to at least two yr after liver transplantation even in patients with risk factors for rejection, with particular renal benefits in specific patient subpopulations.

AbstractParasites can, in theory, have large impacts on the survival of fish populations. One method to evaluate such impacts on anadromous species is to apply manipulative field experiments in which parallel groups of antiparasitically treated and non‐treated fish are simultaneously released and then subsequently recaptured as returning adults. A systematic review and meta‐analysis on all such Norwegian studies on Salmo salar provided a data set for the time period 1996 to 2011 on 118 release groups comprising 657 624 fish released and 3989 recaptured. The overall risk ratio (RR) was estimated to be 1.18 (95% CI: 1.07–1.30). The effect varied strongly between groups, (Higgins I2 = 40.1%). Over 70% of this heterogeneity could be explained by the release location, time period and baseline survival. The most important predictor variable was baseline survival. In groups with low recapture in the control group (low baseline survival), the effect of treatment was high (RR = 1.7), while in groups with high recapture in the control group (high baseline survival), there was no effect of treatment (RR ~ 1.00). The most prevalent parasite in the region affected by the drugs administered was Lepeophtheirus salmonis. Hence, the meta‐analysis supports the hypothesis that L. salmonis contributes to the mortality of S. salar during outward migration. However, the effect of treatment was not consistent, but was evidently strongly modulated by other risk factors. The results suggest that the population‐level effects of parasites cannot be estimated independently of other factors affecting the marine survival of S. salar.
The impact of endodontic access on the biaxial flexure strength of dentine‐bonded crown substrates – an in vitro study
Authors: Kelly R. D. , Palin W. M. , Tomson P. L. , Addison O. 
Published: December 2015

AbstractAimTo investigate how preparation of a simulated access cavity into ceramic materials suitable for the manufacture of dentine‐bonded crowns (DBCs) impacted on biaxial flexural strength (BFS) determined as a monolithic structure and in a more clinically representative resin‐cemented form.MethodologyOne hundred and twenty feldspathic and 120 leucite‐reinforced ceramic disc‐shaped specimens were divided into eight groups (n = 30). All groups received ‘fit’ surface treatments representative of pre‐cementation modifications and of cementation prior to preparation of a representative endodontic access cavity through the sample. BFS was determined for both ‘intact’ and the ‘annular’ disc‐shaped specimens which had received simulated endodontic access. Newly reported analytical solutions were used to calculate BFS of the ‘annular’ specimens. Statistical analysis included two‐way anovas (α = 0.05) and Weibull analysis. Fractographic examination provided insight into the fracture mechanisms.ResultsA two‐way anova identified a significant impact of material (P < 0.01) and of resin coating (P < 0.01) on the mean BFS of intact specimens. For the annular ceramic specimens, the substrate material significantly impacted on mean BFS (P < 0.01), but the effect of resin coating was dependent on the substrate type (P < 0.01).ConclusionsEndodontic access cavity preparation modified the critical defect population of the all‐ceramic restorative materials investigated. The strength of a predominantly glassy ceramic following endodontic access can be maintained if adhesive cementation was used; however, the beneficial effects of adhesive cementation on ceramic reinforcement were lost on leucite‐reinforced ceramics following access cavity preparation. Replacement restoration for these materials would be recommended clinically following endodontic access as opposed to repair of the access cavity using a direct restorative material.
Illuminating vitamin D effects on B cells – the multiple sclerosis perspective
Authors: Rolf Linda , Muris Anne‐Hilde , Hupperts Raymond , Damoiseaux Jan 
Published: December 2015

SummaryVitamin D is associated with many immune‐mediated disorders. In multiple sclerosis (MS) a poor vitamin D status is a major environmental factor associated with disease incidence and severity. The inflammation in MS is primarily T‐cell‐mediated, but increasing evidence points to an important role for B cells. This has paved the way for investigating vitamin D effects on B cells. In this review we elaborate on vitamin D interactions with antibody production, T‐cell‐stimulating capacity and regulatory B cells. Although in vitro plasma cell generation and expression of co‐stimulatory molecules are inhibited and the function of regulatory B cells is promoted, this is not supported by in vivo data. We speculate that differences might be explained by the B‐cell–Epstein–Barr virus interaction in MS, the exquisite role of germinal centres in B‐cell biology, and/or in vivo interactions with other hormones and vitamins that interfere with the vitamin D pathways. Further research is warranted to illuminate this tube‐versus‐body paradox.
