Star power: the evolution of celebrity endorsement research
Authors: Yang Wan 
Published: November 2017

Purpose
The aim of this paper is to summarize the celebrity endorsement literature to identify trends and challenges related to key research areas. Based on a critical review of existing literature, this paper presents several recommendations regarding potential future directions of celebrity endorsement research in hospitality and tourism.

Design/methodology/approach
The paper presents a critical review of literature from both the general marketing and hospitality and tourism fields.

Findings
Over the past decade, significant progress has been made in hospitality and tourism celebrity endorsement research, with several new constructs being revealed and tested. However, the extant findings are rather mixed and inconclusive because industry features have not been systematically examined and study contexts and samples have varied widely. To advance the hospitality and tourism celebrity endorsement research, an extended meaning transfer model with six propositions is proposed. Several areas for future research are also discussed.

Practical implications
This paper offers up-to-date findings on celebrity endorsement to practitioners, and the proposed extended meaning transfer model can provide marketers useful guidelines on selecting appropriate endorsers for their products/brands.

Originality/value
In previous studies, scholars mainly used one or more of the three types of celebrity endorser selection models and only examined specific antecedents of effective endorsement. To date, researchers have not yet conceptualized a modified model that captures the unique features of the hospitality and tourism industry and reconciles the mixed findings in the extant literature. This paper proposes an extended meaning transfer model to explain the endorser selection process, provides a good foundational understanding of the extant celebrity endorsement research and makes several recommendations regarding future research directions for hospitality and tourism scholars with implications for practitioners.

Authors: Kandampully Jay , Zhang Tingting(Christina) , Jaakkola Elina 
Published: November 2017

Purpose
In the contemporary hospitality industry, superior customer experiences are essential in gaining customer loyalty and achieving a competitive advantage. However, limited research addresses this subject. The purpose of this study is to advance scholarly research on customer experience management (CEM) in the hospitality field by providing a comprehensive overview of the key elements of CEM, a framework for managing customer experience and a rich agenda for research.

Design/methodology/approach
An extensive literature review produces a comprehensive overview of the existing knowledge of CEM. A synthesis of previous literature reveals the need for additional, contemporary information sources. The study is, therefore, supplemented by invited commentaries on CEM from senior scholars and hospitality managers.

Findings
The proposed model takes a holistic perspective on managing a positive customer experience, through collaboration among marketing, operations, design, human resources and strategy, in association with technology and social media.

Research limitations/implications
The literature review and commentaries from leading experts reveal six areas for further research on CEM in the hospitality industry.

Originality/value
This study provides a comprehensive, systematic review of CEM literature and detailed understanding of the mechanisms for managing customer experiences in the hospitality industry. It integrates state-of-the-art CEM knowledge in the generic business context, along with principles of hospitality management, and advances CEM research by emphasizing the need for collaboration among marketing, operations and human resources.
Analytic perspectives on online purchasing in hotels: a review of literature and research directions
Authors: Morosan Cristian , Bowen John T. 
Published: November 2017

Purpose
As scholarly research in online purchasing increases in size and scope, understanding the manner in which consumers engage during online purchasing in hotels is critical. The purpose of this study is to provide an analysis of the current online purchasing research pertaining to the hotel industry.

Design/methodology/approach
A content analysis was conducted of 85 peer-reviewed articles published between 2006 and 2016 in hospitality and tourism journals to uncover the most critical aspects of online purchasing in hotels. Keyword searches and specific search parameters (e.g. literature time frame and locus of search) guided the review of the articles selected for the analysis.

Findings
This study recognizes that the discrete transaction per se represents the focal element in the hospitality scholarly research in online purchasing. It also recognizes the importance of the overall encompassing hospitality experience in creating and appropriating value for all stakeholders. Finally, the review found a strong orientation toward self-reported survey data as indicative of online transactions and the steps that precede them online.

Research limitations/implications
The study recognizes the present focus on discrete transactions and recommends expanding the focus to tap into more comprehensive purchasing processes that are mediated by technology.

Practical implications
The analysis presented here offers practitioners insight into the value chain member and consumer behaviors that could be feasibly converted into actionable managerial practices.

Originality/value
In contrast to the reviews discussing online purchasing, this study provides a unique broad analytical perspective on the relationships among buyers, sellers, products, retail interfaces and consumer decision processes that characterize the hotel online purchasing environment, as reflected in the past 10 years of hospitality and tourism literature.
Lean readiness – the case of the European pharmaceutical manufacturing industry
Authors: Garza-Reyes Jose Arturo , Betsis Ioannis E. , Kumar Vikas , Radwan Al-Shboul Moh’d Anwer 
Published: November 2017

PurposeThe purpose of this paper is to assess the quality practices of European pharmaceutical manufacturers to determine the level of readiness of this industrial sector to implement and/or sustain lean manufacturing (LM).Design/methodology/approachAn assessment framework developed by Al-Najemet al.(2013) was adapted to evaluate how ready European pharmaceutical manufacturers are to implement and/or sustain LM. Therefore, the lean readiness (LR) level of these organisations was assessed through six quality practices related to LM. These included: processes, planning and control, human resources, top management and leadership, customer relations, and supplier relations. One research question and three hypotheses were formulated and tested using a combination of descriptive statistics and non-parametric Mann-Whitney tests. Data were collected through a survey questionnaire distributed to 310 European pharmaceutical manufacturers and responded by 37 of these organisations.FindingsOverall, the results of this study indicate an inadequate level of LR for the participating firms. Simultaneously, it was concluded that factors such as company size, type of relationships with suppliers and ISO 9000 certification do not have an effect on the quality practices, and hence LR level, of European pharmaceutical manufacturing organisations.Practical implicationsThis study provides crucial information regarding the LR level of European pharmaceutical manufacturers, which can now be aware of the areas in their practices that require further improvement towards a successful lean journey. Simultaneously, organisations in the pharmaceutical sector that intend to implement LM can consider the results of this study and evaluate their readiness level. Managers can, therefore, refer to this research and use it as a platform to take better decisions regarding what quality aspects of their operations need to be enhanced to successfully deploy or sustain a lean strategy.Originality/valueThis research is one of the very few studies that have focussed on evaluating whether the European pharmaceutical manufacturing industry is ready to successfully implement or sustain LM. Therefore, this research expands the limited existent body of knowledge of LM in this industry.
The effect of oil shocks and cyclicality in hiding Indian twin deficits
Authors: Goyal Ashima , Kumar Abhishek 
Published: November 2017

PurposeThe purpose of this paper is to estimate the relationship between the current account (CA) and fiscal deficit (FD), and the real exchange rate for India, for the managed float period 1996 Q2 to 2015 Q4, after controlling for output growth and oil shocks. It also examines the cyclicality of the CA, the size of each shock, and assesses whether aggregate demand, forward-looking smoothing, or supply shocks dominate outcomes.Design/methodology/approachThe authors use several variants of structural vector autoregression (SVAR), implemented with quarterly Indian data, to control for effects of oil prices, and the output cycle, and then see how FD shocks affect the current account deficit (CAD) and the real exchange rate. For robustness, the authors tried different identifications, changed variable definitions, added new variables, or substituted with other variables. The cyclicality issue is addressed by examining the effect of growth shocks. The relative size of each shock is assessed through co-movement decompositions of the forecast errors. Responses to shocks help identify dominant influences on India’s CAD.FindingsThe CAD is found to be countercyclical. A FD shock raises the CAD, but high impact growth shocks and large variance oil shocks lead to overall divergence of the deficits. There is some support for the aggregate demand channel, but it is moderated by supply shocks and compositional effects. Consumption is sticky rather than forward-looking.Originality/valueThe paper contributes to the literature by including supply shocks, compositional effects, cyclicality, real interest and exchange rate in a theoretically and empirically consistent way for the analysis of twin deficits. The large empirical literature on twin deficits in EMs has not yet done this. There is no study using quarterly data in an SVAR allowing the dynamic relationship between the variables to be explored. The extensions bring in the supply side and compositional effects qualify the working of both the channels, with empirical exercises supporting theoretical predictions.
The more connected, the better? Impact of connectedness on volatility and price discovery in the Korean financial sector
Authors: Jeong DeokJong , Park Sunyoung 
Published: November 2017

PurposeThe purpose of this paper is to empirically analyze the effect of the increasing connectedness among financial institutions in the Korean financial market, as it affects the market microstructure in the stock market. Thus this work, first, analyzes the trend and characteristics of connectedness in the Korean financial sector. This work then demonstrates the impacts of connectedness on volatility and price discovery in the stock market.Design/methodology/approachThe entire Korean financial sector is analyzed from January 1990 to July 2015, including the periods of the 1997 Asian crisis and the 2007/2008 global financial crisis. This paper quantifies the connectedness between financial institutions using network methodology. Densely connectedness specifically refers to the cases in which a node experiences strong-lagged return spillover from and/or to itself.FindingsConnectedness is established as an important determinant of stock price discovery. This paper illustrates that connectedness increases on significant economic events such as the 1997 Asian crisis and the 2007/2008 global financial crisis. Furthermore, this paper demonstrates that the more densely connected a particular financial institution, the more volatile the stock price and the less accurate the stock price quality.Research limitations/implicationsUnderstanding the financial system from a network perspective has been on the rise after the 2007/2008 global financial crisis. This work helps regulators and policy makers understand the full implications of introducing new policies that can more closely connect financial institutions.Originality/valueThis paper precisely captures financial institutions’ connectedness by including all types of financial institutions at the micro level. Additionally, this paper links connectedness to market microstructure in the stock market.
Free‐living chemoautotrophic and particle‐attached heterotrophic prokaryotes dominate microbial assemblages along a pelagic redox gradient

Published: November 2017

SummaryUsing the anoxic Cariaco Basin as a natural laboratory, particle association of bacterial and archaeal taxa was assessed by iTag sequencing and qPCR gene assays of samples spanning an oxic–anoxic–euxinic gradient. A total of 10%–12% of all bacterial and archaeal cells were found in the particle‐associated (PA) fraction, operationally defined as prokaryotes captured on 2.7 µm membranes. Both redox condition and size fraction segregated bacterial taxa. Archaeal taxa varied according to redox conditions, but were similar between size fractions. Taxa putatively associated with chemoautotrophic sulfur oxidation and nitrification dominated the free‐living (FL) fraction throughout the oxycline (< 1–120 µM O2) and upper anoxic layer. Bacteria in the oxycline's PA fraction included taxa known to be aerobic and anaerobic chemoorganotrophs. At shallow anoxic depths, PA taxa were primarily affiliated with anaerobic sulfate (
)‐reducing lineages. PA fractions in the most sulfidic samples were dominated by taxa affiliated with CH4 oxidizing, fermenting and
reducing lineages. Prevalence of particle‐associated
‐reducing taxa and abundant sulfur‐oxidizing taxa in both size fractions across the oxic–anoxic interface is consistent with the cryptic sulfur cycling concept. Bacterial assemblage diversity in the PA fraction always exceeded the FL fraction except in the most oxic samples, whereas Archaeal diversity was not consistently different between size fractions. Our results suggest that these particle‐associated and free‐living bacterial assemblages are functionally different and that the interplay between particle microhabitats and surrounding geochemical regimes is a strong selective force shaping microbial communities throughout the water column.
Pregnancy weight gain by gestational age and stillbirth: a population‐based cohort study
Authors: Johansson K , Hutcheon JA , Bodnar LM , Cnattingius S , Stephansson O 
Published: November 2017

ObjectiveTo study the association between total and early pregnancy (<22 completed weeks) weight gain and risk of stillbirth, stratified by early‐pregnancy body mass index (BMI).DesignPopulation‐based cohort study.SettingStockholm‐Gotland Region, Sweden.PopulationPregnant women with singleton births (n = 160 560).MethodsPregnancy weight gain was standardised into gestational age‐specific z‐scores. For analyses of total pregnancy weight gain, a matched design with an incidence density sampling approach was used. Findings were also contrasted with current Institute of Medicine (IOM) weight gain recommendations.Main outcome measuresStillbirth defined as fetal death at ≥22 completed weeks of gestation.ResultsFor all BMI categories, there was no statistical association between total or early pregnancy weight gain and stillbirth within the range of a weight gain z‐score of −2.0 SD to +2.0 SD. Among normal‐weight women, the adjusted odds ratio of stillbirth for lower (−2.0 to −1.0 SD) and higher (+1.0 to +1.9 SD) total weight gain was 0.85 (95% CI; 0.48–1.49) and 1.03 (0.60–1.77), respectively, as compared with the reference category. Further, there were no associations between total or early pregnancy weight gain and stillbirth within the range of weight gain currently recommended by the IOM. For the majority of the BMI categories, the point estimates at the extremes of weight gain values (<−2.0SD and ≥2.0 SD) suggested protective effects of low weight gain and increased risks of high weight gain, but estimates were imprecise and not statistically significant.ConclusionWe found no associations between total or early pregnancy weight gain and stillbirth across the range of weight gain experienced by most women.Tweetable abstractThere was no association between weight gain during pregnancy and stillbirth among most women.

Published: November 2017

SummaryThe substitution of natural gas by renewable biomethane is an interesting option to reduce global carbon footprint. Syngas fermentation has potential in this context, as a diverse range of low‐biodegradable materials that can be used. In this study, anaerobic sludge acclimatized to syngas in a multi‐orifice baffled bioreactor (MOBB) was used to start enrichments with CO. The main goals were to identify the key players in CO conversion and evaluate potential interspecies metabolic interactions conferring robustness to the process. Anaerobic sludge incubated with 0.7 × 105 Pa CO produced methane and acetate. When the antibiotics vancomycin and/or erythromycin were added, no methane was produced, indicating that direct methanogenesis from CO did not occur. Acetobacterium and Sporomusa were the predominant bacterial species in CO‐converting enrichments, together with methanogens from the genera Methanobacterium and Methanospirillum. Subsequently, a highly enriched culture mainly composed of a Sporomusa sp. was obtained that could convert up to 1.7 × 105 Pa CO to hydrogen and acetate. These results attest the role of Sporomusa species in the enrichment as primary CO utilizers and show their importance for methane production as conveyers of hydrogen to methanogens present in the culture.
Development of a specific fluorescent phage endolysin for in situ detection of Clostridium species associated with cheese spoilage
Authors: Gómez‐Torres Natalia , Dunne Matthew , Garde Sonia , Meijers Rob , Narbad Arjan , Ávila Marta , Mayer Melinda J. 
Published: November 2017

SummaryLate blowing defect (LBD) is a major cause of spoilage in cheeses, caused by the growth of Clostridium spp. in the cheese matrix. We investigated the application of CTP1L, a bacteriophage endolysin active against Clostridium tyrobutyricum, and its enzymatically active and cell wall‐binding domains (EAD and CBD) attached to green fluorescent protein (GFP) to detect dairy‐related Clostridium species by fluorescence microscopy. GFP‐CTP1L and GFP‐CBD demonstrated specificity for Clostridium spp. by labelling 15 and 17 of 20 Clostridium strains, respectively, but neither bound to other members of the cheese microbiota. However, GFP‐EAD did not label any Clostridium strain tested. Unexpectedly, GFP‐CTP1L and GFP‐CBD were also able to bind to clostridial spores. In addition, GFP‐CBD allowed us to visualize the vegetative cells of C. tyrobutyricum directly in the matrix of a LBD cheese. Site‐directed mutants of GFP‐CTP1L and GFP‐CBD were made to examine the amino acids involved in binding and oligomer formation. Oligomerization was not essential for binding, but specific mutations in the CBD which affected oligomer formation also affected binding and lytic activity. We conclude that GFP‐CTP1L and GFP‐CBD could be good biomarkers for rapid detection of Clostridium spores in milk, so measures can be taken for the prevention of LBD in cheese, and also provide effective tools to study the development of Clostridium populations during cheese ripening.
Assessment of Future Drought Conditions in the Chesapeake Bay Watershed
Authors: Kang Hyunwoo , Sridhar Venkataramana 
Published: November 2017

AbstractImpacts of climate change on the severity and intensity of future droughts can be evaluated based on precipitation and temperature projections, multiple hydrological models, simulated hydrometeorological variables, and various drought indices. The objective of this study was to assess climate change impacts on future drought conditions and water resources in the Chesapeake Bay (CB) watershed. In this study, the Soil and Water Assessment Tool (SWAT) and the Variable Infiltration Capacity model were used to simulate a Modified Palmer Drought Severity Index (MPDSI), a Standardized Soil Moisture index (SSI), a Multivariate Standardized Drought Index (MSDI), along with Coupled Model Intercomparison Project Phase 5 (CMIP5) climate models for both historical and future periods (f1: 2020‐2049, f2: 2050‐2079). The results of the SSI suggested that there was a general increase in agricultural droughts in the entire CB watershed because of increases in surface and groundwater flow and evapotranspiration. However, MPDSI and MSDI showed an overall decrease in projected drought occurrences due to the increases in precipitation in the future. The results of this study suggest that it is crucial to use multiple modeling approaches with specific drought indices that combine the effects of both precipitation and temperature changes.

BackgroundPreclinical evidence suggests that general anesthetics can dose dependently induce neurodegeneration in the developing brains of animals which can be reliably determined by measurement of blood S100β, but this correlation remains unclear in humans. We hypothesized that S100β would not be increased in cord arterial blood of fetuses exposed briefly to general anesthetics during a C‐section, compared with epidural anesthesia.MethodsA prospective observational clinical study comparatively measured changes of brain damage biomarker S100β ratio of umbilical artery over vein (changes after fetus circulation) immediately after delivery under C‐section with either epidural or general anesthesia. Newborn blood gas measurements, APGAR scores, and maternal well‐being were also compared.ResultsCompared with epidural anesthesia, general anesthesia resulted in the lower S100β ratio of umbilical artery over the vein (medium 2.64 [quartiles 1.39, 3.45] vs. medium 1.59 [quartiles 0.88, 2.01], P = 0.031), without changing the S100β level in the vein of the mother. There was no significant difference between general and epidural anesthesia when comparing other maternal and newborn parameters.ConclusionS100β levels in newborn after C‐section is lower with general anesthesia than epidural anesthesia, with unclear mechanisms.
