Mobile usage in travel: bridging the supplier-user gap
Authors: Linton Heather , Kwortnik Robert J. 
Published: January 2019

PurposeConsumer-driven technology innovations are transforming travel behavior. However, travel suppliers are still struggling to grasp their customers’ desires regarding mobile device usage in travel and also face other barriers. This paper aims to take a two-pronged approach to identify the gap between what travelers would like to do on mobile devices and what suppliers currently offer and to provide insights from technology industry experts on future trends.Design/methodology/approachThis paper uses two exploratory studies: a consumer survey to understand travelers’ needs and wants regarding mobile devices and a qualitative study to learn more about how travel suppliers are responding and to identify barriers. Statistical techniques include ANOVA tests to identify individual differences and factor analyses to discover patterns in the data.FindingsConsumers would like to do more on mobile devices than is currently available; therefore, industry providers must be more forward-thinking with technology development and overcome the barriers identified in this paper.Research limitations/implicationsGiven the limitations to existing supplier offerings and capabilities, travelers were asked what they would like to do on mobile devices. Although marketing and technology personnel from various companies were interviewed, other perspectives exist.Originality/valueThis paper contributes to the technology adoption and service-supplier innovation literatures by helping mobile technology service providers in the travel industry better understand and bridge the supplier-user gap. Suggestions to close this gap and predictions from technology industry experts are included to direct future actions.
The social servicescape: understanding the effects in the full-service hotel industry
Authors: Line Nathaniel Discepoli , Hanks Lydia 
Published: January 2019

PurposeUnderstanding how other customers affect hotel consumption behavior is an important topic in the hospitality literature. While existing research has typically explored the effects of active interactions among consumers, this study aims to better understand the effects of passive interactions. Accordingly, this research conceptualizes the hotel social servicescape as a function of the mere presence of the other social actors that occupy the hotel’s shared consumption space.Design/methodology/approachTo operationalize this construct, data were collected from a sample of 1,019 recent consumers of full-service hotel experience in the USA.FindingsThe findings suggest that the social servicescape can significantly affect satisfaction and behavioral intentions in the domain of leisure-driven hotel experiences.Research limitations/implicationsThe results support the hypothesis that the mere presence of others significantly affects leisure travelers’ perceptions of the hotel consumption experience. Accordingly, these findings indicate that the makeup of the hotel servicescape is not limited to the traditionally acknowledged physical elements of the space.Practical implicationsThe results suggest that in addition to managing the physical aspects of the service environment, hotel managers should take steps to manage the social aspects of the servicescape as well.Originality/valueThis paper is the first to provide an operational account of the social servicescape in the domain of full-service hotels. Additionally, nomological validity is established by examining the downstream effects on satisfaction and behavioral intentions.
Carbon footprint and financial evaluation of an aeronautic component production using different manufacturing processes
Authors: Loukopoulos Andreas , Katsiropoulos Christos Vasilios , Pantelakis Spiros G. 
Published: January 2019

Purpose
The purpose of this paper is to quantify the environmental footprint and cost and thus compare different manufacturing scenarios associated with the production of aeronautical structural components.

Design/methodology/approach
A representative helicopter canopy, i.e., canopy of the EUROCOPTER EC Twin Star helicopter described in Pantelakis et al. (2009), has been considered for the carbon footprint (life cycle energy and climate change impact analysis) along with the life cycle costing analysis. Four scenarios – combinations of different manufacturing technologies (autoclave and resin transfer molding (RTM)) and end-of-life treatment scenarios (mechanical recycling and pyrolysis) are considered.

Findings
Using the models developed the expected environmental and cost benefits by involving the RTM technique have been quantified. The environmental impact was expressed in terms of energy consumption and of Global Warming Potential-100. From an environmental standpoint, processing the canopy using the RTM technique leads to decreased energy demands as compared to autoclaving because of the shorter curing cycles exhibited from this technique and thus the less time needed. As far as the financial viability of both processing scenarios is concerned, the more steps needed for preparing the mold and the need for auxiliary materials increase the material and the labor cost of autoclaving as compared to RTM.

Originality/value
At the early design stages in aeronautics, a number of disciplines (environmental, financial and mechanical) should be taken into account in order to evaluate alternative scenarios (material, manufacturing, recycling, etc.). In this paper a methodology is developed toward this direction, quantifying the environmental and financial viability of different manufacturing scenarios associated with the production of aeronautical structures.
Gamification and entrepreneurial intentions
Authors: Ruiz-Alba José L. , Soares Anabela , Rodríguez-Molina Miguel Angel , Banoun Arnaud 
Published: January 2019

Purpose
The purpose of this paper is to investigate how gamification can influence entrepreneurial intentions (EI) of a group of users of an online platform provided by a private company.

Design/methodology/approach
A quantitative research strategy was used with a sample of 220 respondents. These respondents were tested before and after the gamification experience.

Findings
Main findings support literature suggesting a clear effect of attitudes towards behaviour and perceived behavioural control on EI, in line with the theory of planned behaviour (TPB). Once the basic assumptions of TPB were confirmed, the authors tested the effects of gamification comparing before and after results. Main findings highlight an increase of these effects after the gamification experience, aligned with the self-determination theory.

Practical implications
These findings suggest that gamification is able to influence entrepreneurial behaviours. This contributes to both companies and educators’ knowledge on training for EI with gamification and the use of online platforms to this effect. Recommendations are provided.

Originality/value
This is the first study that investigates the impact of gamification on EI and how gamification can influence the different relationships between the antecedents of EI.

Published: January 2019

ProblemThe Staphylococcus aureus has been found to be associated with clinical endometritis of cow. The result of oral antibiotic remains poor. Therefore, this study investigates the role of nisin in endometritis.Method of studyThe effect of nisin on the growth and cell wall of S aureus were determined in vitro. Besides the blank control group, animals with established post‐partum were inoculated with 0.1 mL S aureus intravaginally. Two days post‐inoculation, the animals were administered nisin (25 mg/kg), kanamycin (30 mg/kg), and water (model group) for 7 days. On the seventh day, serum and uterine organs were obtained for pro‐ and anti‐inflammatory analysis. The uterine tissue samples were weighed, and histopathological analysis was performed.ResultsThe results showed that nisin had an inhibitory effect on the growth and cell wall formation of S aureus. Nisin and kanamycin treatment prevented a S aureus‐induced decrease in pro‐inflammatory cytokines and promoted an increase in the level of serum anti‐inflammatory cytokines in the endometrium of these animals. Nisin and kanamycin, significantly decreased (P < 0.05) the endometritis‐induced increases in uterine weight, restored endometrial architecture and significantly (P < 0.05) normalized uterine neutrophils to control levels. Additionally, improved levels of B7‐2, IFN‐γ, IL‐2, and IL‐8 were observed when treated with nisin.ConclusionOur findings suggest that nisin compared favorably with kanamycin in endometritis prevention, suggesting that nisin can be used in S aureus‐induced endometritis by protecting the uterus from S aureus infection.

Published: January 2019

AbstractIntroductionSecond trimester asymptomatic cervical dilation is a significant risk factor for early preterm birth. The objective of this study is to evaluate whether transvaginal ultrasound cervical length (CL) predicts asymptomatic cervical dilation on physical exam in women with short cervix (CL ≤25 mm) and no prior preterm birth.Material and methodsSecondary analysis of a randomized trial on pessary in asymptomatic singletons without prior preterm birth diagnosed with CL ≤25 mm between 18+0/7 and 23+6/7 weeks. Participants had transvaginal ultrasound and physical cervical exam and were randomized to pessary or no pessary with all patients with cervical length ≤20 mm offered vaginal progesterone. The primary outcome was to determine whether CL was predictive of asymptomatic physical cervical dilation ≥1 cm using receiver operating characteristic curve.ResultsIn all, 119 women were included. Based on receiver operating characteristic curve, CL ≤11 mm was best predictive of cervical dilation ≥1 cm, with 75% sensitivity, 80% specificity, and area under the curve 0.73 (0.55‐0.91), P = 0.009. Cervical length ≤11 mm had increased incidence of cervical dilation ≥1 cm on physical exam (30% vs 3%, odds ratio 12.29 (3.05‐49.37) P < 0.001) with a negative predictive value of 97%. Patients with ≥1 cm dilation had increased preterm birth <37 weeks (75% vs 39%, P = 0.03) compared to those not dilated. Women with a CL ≤11 mm had increased preterm birth <37 weeks (77% vs 31%, P < 0.001), preterm birth <34 weeks (63% vs 22%, P < 0.001), and lower birthweight (1552 ± 1047 vs 2560 ± 1072 g, P < 0.001) compared to women with CL >11 mm.ConclusionsAmong singletons without prior preterm birth diagnosed with short cervix (≤25 mm), CL ≤11 mm may identify a subgroup of patients at high risk for asymptomatic cervical dilation and poor perinatal outcome. Physical exam should be considered and adjunctive preterm birth prevention measures should be studied in singletons with CL ≤11 mm.

Published: January 2019

AbstractAimTo determine the relationship between neonatal phototherapy and future risk of clinically significant hemangioma.MethodsWe analysed a cohort of 678 879 infants born after 34 weeks gestation comprising 3 975 242 person‐years of follow‐up over 11 years (2006–2016). The exposure was phototherapy the first 28 days of life. The outcome was hemangioma that required in‐hospital treatment during follow‐up. We estimated hazard ratios (HR) and 95% confidence intervals (CI) for the association of phototherapy with risk of hemangioma, accounting for preterm birth, low birthweight and congenital anomalies.ResultsThe incidence of hemangioma was greater in neonates who received phototherapy than in untreated infants, but there was no association in adjusted models (HR 1.19, 95% CI 0.89–1.58). Risk of hemangioma was elevated in infants who received phototherapy and were born late preterm (HR 2.35, 95% CI 1.51–3.64), with low birthweight (HR 1.91, 95% CI 1.12–3.24), or with anomalies (HR 5.09, 95% CI 3.42–7.58). Without phototherapy, these three risk factors were more weakly associated with hemangioma.ConclusionNeonatal phototherapy in infants with predisposing risk factors may increase the chance of hemangioma, but confirmation in further studies is needed.

SUMMARYBackgroundChronic hepatitis B has been linked to lymphoma with contradictory results.AimTo investigate the association between chronic hepatitis B and lymphoma by using a nationwide population‐based cohort.MethodsRecords of patients diagnosed with chronic hepatitis B (hepatitis B virus [HBV] cohort) or without (non‐HBV cohort) during 2004‐2007 were retrieved from the Taiwan National Health Insurance Research Database. Age, sex, comorbidities, and medical visits were matched using propensity scores between both cohorts, and they were followed up longitudinally until 2012 to determine any new lymphoma development.ResultsA total of 203 031 patients were included in each cohort with a mean follow‐up of 7‐9 years. The lymphoma incidence rate was significantly higher in the HBV cohort than in the non‐HBV cohort (29.4 vs 15.9 per 100 000 person‐years, P < 0.0001). After adjustment for comorbidities and medical visits, HBV infection was found to be an independent risk factor associated with the development of lymphoma (hazard ratio [HR]: 2.07, 95% confidence interval [CI]: 1.76‐2.43, P < 0.0001) and non‐Hodgkin's lymphoma (HR: 2.18, 95% CI: 1.80‐2.65, P < 0.0001); specifically with an increased risk of diffuse large B‐cell lymphoma (HR: 2.69, 95% CI: 2.05‐3.52, P < 0.0001), other B‐cell lymphoma (HR: 3.11, 95% CI: 1.89‐5.11, P < 0.0001), and also for multiple myeloma (HR: 1.63, 95% CI: 1.10‐2.42, P = 0.016). The association was significant even after excluding lymphoma development within the first year (HR: 2.08, 95% CI: 1.75‐2.47, P < 0.0001).ConclusionsChronic hepatitis B is temporally associated with a 2‐fold increased risk of lymphoma, particularly with B‐cell non‐Hodgkin's lymphoma, and also an increased risk for multiple myeloma.

AbstractIn Japan, the first endoscopic surgery, a laparoscopic cholecystectomy, was performed in 1990. Since then, the operative procedure has been standardized, and the safety and usefulness of endoscopic surgery have been evaluated. In accordance with the social acceptance of endoscopic surgery as a less‐invasive surgery, the number of endoscopic procedures has been increasing in all surgical domains. The Japan Society for Endoscopic Surgery (JSES) has played an important role in the development of endoscopic surgery in Japan. For example, JSES established a technical skills certification system for surgeons to train instructors how to teach safe endoscopic surgery, and the organization performs a national survey every 2 years. In 2015, a total of 211 953 patients underwent endoscopic surgery in all surgical domains, including abdominal, thoracic, mammary and thyroid gland, cardiovascular, obstetrics and gynecology, urologic, orthopedic, and plastic surgery. The course of laparoscopic surgery's development and its current status are reported here based on the results of the most recent questionnaire survey conducted by JSES.
Winter wheat (Triticum aestivum) response to Barley yellow dwarf virus at various nitrogen application rates in the presence and absence of its aphid vector, Rhopalosiphum padi

Published: January 2019

AbstractBarley yellow dwarf (BYD) is one of the most common diseases of cereal crops, caused by the phloem‐limited, cereal aphid‐borne Barley yellow dwarf virus (BYDV) (Luteoviridae). Delayed planting and controlling aphid vector numbers with insecticides have been the primary approaches to manage BYD. There is limited research on nitrogen (N) application effects on plant growth, N status, and water use in the BYDV pathosystem in the absence of aphid control. Such information will be essential in developing a post‐infection management plan for BYDV‐infected cereals. Through a greenhouse study, we assessed whether manipulation of N supply to BYDV‐infected winter wheat, Triticum aestivum L. (Poaceae), in the presence or absence of the aphid vector Rhopalosiphum padi L. (Hemiptera: Aphididae), could improve N and/or water uptake, and subsequently promote plant growth. Similar responses of shoot biomass and of water and N use efficiencies to various N application rates were observed in both BYDV‐infected and non‐infected plants, suggesting that winter wheat plants with only BYDV infection may be capable of outgrowing infection by the virus. Plants, which simultaneously hosted aphids and BYDV, suffered more severe symptoms and possessed higher virus loads than those infected with BYDV only. Moreover, in plants hosting both BYDV and aphids, aphid pressure was positively associated with N concentration within plant tissue, suggesting that N application and N concentration within foliar tissue may alter BYDV replication indirectly through their influence on aphid reproduction. Even though shoot biomass, tissue N concentration, and water use efficiency increased in response to increased N application, decision‐making on N fertilization to plants hosting both BYDV and aphids should take into consideration the potential of aphid outbreak and/or the possibility of reduced plant resilience to environmental stresses due to decreased root growth.
Reliably Assessing Growth with Longitudinal Diagnostic Classification Models
Authors: Madison Matthew J. 
Published: January 2019

AbstractRecent advances have enabled diagnostic classification models (DCMs) to accommodate longitudinal data. These longitudinal DCMs were developed to study how examinees change, or transition, between different attribute mastery statuses over time. This study examines using longitudinal DCMs as an approach to assessing growth and serves three purposes: (1) to define and evaluate two reliability measures to be used in the application of longitudinal DCMs; (2) through simulation, demonstrate that longitudinal DCM growth estimates have increased reliability compared to longitudinal item response theory models; and (3) through an empirical analysis, illustrate the practical and interpretive benefits of longitudinal DCMs. A discussion describes how longitudinal DCMs can be used as practical and reliable psychometric models when categorical and criterion‐referenced interpretations of growth are desired.
First field evidence for alloparental egg care in cooperatively breeding fish
Authors: Josi Dario , Taborsky Michael , Frommen Joachim G. 
Published: January 2019

AbstractHelping behaviour in cooperative breeders has been intensively studied in many animal taxa, including arthropods, birds and mammals. In these highly social systems, helpers typically engage in brood care and the protection of dependent young. Such helping systems also exist in cooperatively breeding cichlid species of Lake Tanganyika. However, breeding in these species happens in clefts, narrow holes or shelters underneath stones. Therefore, direct brood care by breeders and helpers has thus far only been observed under artificial laboratory conditions. Under natural conditions, brood care behaviour has been estimated indirectly by determining the time spent in the breeding chamber, or by the number of visits to the breeding chamber. The reliability of such substitutes needs to be validated, for instance, by demonstrating alloparental egg care of helpers through direct observations in nature. Here, we describe direct egg care by a male helper of the cooperatively breeding cichlid Neolamprologus savoryi in the field. The helper inspected and cleaned the eggs and defended them against predators. By reconstructing the genetic relatedness using microsatellite markers, we show that the helper was the son of the breeding male, but unrelated to the breeding female. The genetic mother of the helper was defending a different territory next to the one where the helper showed alloparental egg care. This indicates that the helper had dispersed inside the male territory to assist another female to care for his half‐siblings. These results demonstrate alloparental egg care without reproductive share in a fish species under natural conditions, underlining that helping behaviour in cooperatively breeding fish has a strong non‐self‐serving component.
Colopexy dehiscence preceding an episode of large colon volvulus, followed by repeat colopexy, in three Thoroughbred broodmares
Authors: Hall M. D. , Rodgerson D. H. 
Published: January 2019

SummaryThree Thoroughbred mares that had undergone previous colopexy following surgical correction of a large colon volvulus presented for colic signs unresponsive to medical management. Exploratory laparotomy was elected and a midline celiotomy was performed in the caudal aspect of the ventral abdomen in each mare. Examination of the cranial abdomen revealed the large colon was not adhered to the ventral body wall, indicating dehiscence of the previous colopexy. Further examination of the abdomen in each mare revealed a 360‐degree large colon volvulus. The previous colopexy site appeared as a linear haemorrhagic area of fibrosis in one mare and a pale area of fibrosis in two mares. The large colon volvulus was corrected and a second colopexy was then performed using the same technique as the first colopexy – by incorporating 10–12 cm of the lateral free band of the left ventral colon into the midline linea alba closure using number 3 polyglactin 910 (Vicryl®). The mares each recovered uneventfully from anaesthesia and were discharged 2–10 days later. Two of the mares are still alive at the time of manuscript submission, 475 and 789 days post‐operatively. The third mare survived 4 years post‐operatively, following which she was lost to follow‐up. Data available from our clinic indicate an incidence rate of 0.79% for colopexy dehiscence followed by a repeat episode of large colon volvulus. This phenomenon should be considered as a differential diagnosis when a mare that previously underwent a colopexy presents with severe signs of colic.
