High-performance work practices, career satisfaction, and service recovery performance: a study of flight attendants
Authors: Karatepe Osman M. , Vatankhah Sanaz 
Published: April 2015

Purpose– The purpose of this paper is to propose and test a conceptual model that examines career satisfaction (CSAT) as a mediator of the effects of high-performance work practices (HPWPs) on service recovery performance, drawing from social information processing and Bagozzi’s (1992) reformulation of attitude theories.Design/methodology/approach– Data were gathered from flight attendants, with a time lag of two weeks in the private airline companies in Iran. The relationships were gauged using structural equation modeling.Findings– The results suggest that career opportunities seem to be the most important indicator of HPWPs, followed by rewards, selective staffing, empowerment, teamwork, job security and training. The results further suggest that the availability of HPWPs boosts flight attendants’ CSAT and that, in turn, results in elevated levels of service recovery performance.Originality/value– This study contributes to the current literature by linking HPWPs, as manifested by selective staffing, job security, training, empowerment, rewards, teamwork and career opportunities, to service recovery performance through CSAT based on data obtained from flight attendants.

Nakamura, I., Goto, Y. & Sato, K. (2015) . Journal of Animal Ecology, 84, 590–603.Logging cameras and accelerometers have opened our eyes to the secret lives of many enigmatic species. Here some of the new opportunities provided by this technology are reviewed. Recent discoveries are highlighted including the observation of selective feeding on energy‐rich parts of prey. As such, biologging cameras provide new opportunities for consideration of selective feeding within the same sort of theoretical framework (marginal value theory/optimal foraging) that exploitation of prey patches has been examined. A recent study with the world's largest bony fish, the ocean sunfish (Mola mola), is highlighted where animal‐borne cameras allowed the ground‐truthing of data sets collected with depth recorders and accelerometers. This synergistic use of a range of biologging approaches will help drive an holistic understanding of the free‐living behaviour of a range of species.

Published: April 2015

Summary

The recent development of miniaturized saltwater immersion geolocators has made it possible to track and record activity of even the smallest seabird species over extended periods of time.

The resulting activity data comprise of various time stamps and immersion times integrated over 10‐min intervals. Generally, such data sets are large and complex which makes analysis a daunting task, especially in the absence of dedicated software solutions.

We developed Actave.net as a freely accessible, web‐based (http://www.actave.net) analysis tool for complex activity data that provides cloud‐based and automatic computation of daily aggregates of various activity parameters based on recorded immersion data. The tool furthermore calculates various astronomical parameters (e.g. moon illumination) based on locational information derived from geolocation.

Actave.net provides maps and graphs for data exploration, download of processed data for modelling and statistical analysis, and tools for sharing results with other users (e.g. collaborators). Currently, the tool supports the most frequently used M‐Series immersion loggers (BAS/Biotrack Ltd), but support for a broader range of device types as well as expanded analysis functionality is planned for future releases.

Published: April 2015

BackgroundVitamin D deficiency is common. What the optimum level of vitamin D in pregnancy and whether vitamin D supplementation in pregnancy confers improved health benefits remain controversial.AimTo assess vitamin D status in pregnant women in a maternity service that recommends routine antenatal screening and advises supplementation where necessary, and to assess relationships between early pregnancy vitamin D levels and changes in vitamin D across pregnancy with pregnancy outcomes.Materials and MethodsVitamin D serum concentrations were measured in early and late pregnancy. The relationships between initial vitamin D status, maternal factors and pregnancy outcomes were estimated. Change in vitamin D over pregnancy was quantified. The relationship between change in vitamin D over pregnancy and pregnancy outcomes was also estimated.ResultsOf 1550 women, 849 (55%) were vitamin D deficient (<50 nmol/L), 571 (37%) were insufficient (50–74 nmol/L), and 130 (8%) were replete (≥75 nmol/L) in early pregnancy. Factors associated with deficiency were increased body mass index, pregnancy in either winter or spring months, and maternal country of birth (South‐East, South and East Asia, and Africa). Vitamin D deficiency or insufficiency in early pregnancy was significantly associated with developing gestation diabetes mellitus. Levels of vitamin D significantly increased over pregnancy among nonreplete women. Increasing vitamin D over pregnancy was not related to pregnancy outcomes.ConclusionVitamin D ‘deficiency’ is common but may not be associated with most adverse pregnancy outcomes. Routine vitamin D testing of all pregnant women does not appear warranted.

Published: April 2015

AbstractBackgroundPatients with elevated basal tryptase (sBT) >15 μg/l and anaphylaxis may have an underlying mastocytosis. A monoclonal mast cell activation syndrome with aberrant mast cells (MC) at extracutaneous sites has been described in patients with severe hypotension or anaphylaxis.MethodsAs MC in patients with elevated sBT might be altered in the skin as well, we studied MC in normal neck skin in anaphylaxis and urticaria patients with elevated sBT.ResultsA mean of 93.1 (SD 19.1) MC/mm² was counted in normal neck skin in 14 patients with anaphylaxis, 84.0 (SD 13.6) in seven patients with urticaria, 142.0 (SD 24.0) in two patients with eczema, 124.4 (SD 43.2) in five patients with systemic mastocytosis (SM) in comparison with autopsy skin (39.1 MC/mm², SD 12.4). In five of 14 (35.7%) of the anaphylaxis and three of five (60%) SM patients more than 25% of MC were spindle shaped and expressed CD25 antigen.ConclusionsWe could show for the first time that the normal skin can harbour clonal MC in anaphylaxis patients. Analogous to the criteria for mastocytosis, we suggest a skin score criteria including an elevated number of MC, spindle shape, CD25 expression, c‐Kit mutation and sBT values >20 μg/l. In patients with anaphylaxis and elevated sBT, skin should be biopsied and, as with the approach for mastocytosis diagnosis in the bone marrow, MC should be analysed for their number, clonality and c‐Kit mutation. This approach should be confirmed in further studies. Patients with aberrant skin MC should be handled as mastocytosis patients.

Published: April 2015

AbstractPurposeTo quantify subjective visual metamorphopsia in newly diagnosed patients suffering from diabetic macular oedema (DME) and other macular abnormalities and to evaluate anti‐VEGF treatment effect.MethodsPatients with DME, subfoveal choroidal neovascularization (CNV) secondary to age‐related macular degeneration (AMD) or retinal venous occlusion (RVO) were recruited. Metamorphopsia score (Mscore) was calculated using M‐Charts at baseline and at the end of a series of anti‐VEGF injections.ResultsFifteen eyes of 10 patients with DME, 14 eyes of 13 patients with AMD‐CNV and five patients with RVO were included in this study. At baseline, positive Mscore was observed in 46.6% of eyes with DME, 50% of eyes with AMD‐CNV and four of five eyes with RVO. Treatment led to a complete metamorphopsia reduction (Mscore = 0) in 71.4% of DME patients, 35.7% of AMD and 0% of RVO patients.ConclusionWe suggest that the M‐charts may serve as an additional test for diagnosis and follow‐up, complementary to morphological evaluation by imaging, in diabetic patients facing their first anti‐VEGF treatment.
Endoscopic appearance and location dictate diagnostic yield of biopsies in eosinophilic oesophagitis

Published: April 2015

SummaryBackgroundAcknowledging that eosinophilic esophagitis (EoE) is a disease with variable involvement throughout the oesophagus, studies have suggested a minimum of five biopsies to diagnose EoE. Although it is accepted that furrows and exudates appear to represent areas of inflammation, no research to date has looked specifically at EoE endoscopic findings to see if eosinophilic infiltrate correlates with specific endoscopic findings.AimTo evaluate the distribution of eosinophils in EoE and determine whether endoscopic appearances predict the degree of eosinophilia at various locations of the oesophagus.MethodsWe performed a prospective cross sectional study of EoE (treated and untreated) patients to study the distribution of eosinophils according to endoscopic findings. The oesophagus of 10 EoE patients were biopsied up to 32 times in a circumferential manner. The mucosal changes were documented at the site of each biopsy. Histological determination of eosinophil counts and related histopathology of the oesophagus were then correlated with endoscopic findings. Similar biopsy assessments were made in treated (resolved) EoE patients (n = 6) to determine the permanence of specific endoscopic appearances.ResultsA total of 16 patients were biopsied (10 EoE, 6 treated EoE). A total of 432 biopsies were obtained in all with 294 biopsies from 10 EoE subjects. Eosinophil density was increased distally in the majority of EoE patients. Biopsies performed in areas of exudates and furrows demonstrated higher eosinophil counts. Lines and normal‐appearing oesophagi in EoE subjects were not commonly associated with elevated eosinophil counts (>15 eos/HPF). Rings alone without associated furrows or plaques did not demonstrate elevated eosinophil counts and were seen in resolved EoE (Rx‐EoE) as well as in active EoE patients.ConclusionsEosinophilic esophagitis remains a variable disease with some patients manifesting extensive disease throughout the oesophagus. Characteristics of furrows and exudates found during endoscopy are associated with higher peak eosinophil counts, requiring fewer biopsies to make a diagnosis. Lines and otherwise normal appearances of the oesophagus suggest a milder mucosal eosinophilia, requiring substantial biopsies to adequately identify fields with diagnostic eosinophil counts.
Marginal and happy? The need for uniqueness predicts the adjustment of marginal immigrants
Authors: Debrosse Régine , de la Sablonnière Roxane , Rossignac‐Milon Maya 
Published: April 2015

Marginalization is often presented as the strategy associated with the worst adjustment for immigrants. This study identifies a critical variable that buffers marginal immigrants from the negative effects of marginalization on adjustment: The need for uniqueness. In three studies, we surveyed immigrants recruited on university campuses (n = 119, n = 116) and in the field (n = 61). Among marginal immigrants, a higher need for uniqueness predicted higher self‐esteem (Study 1), affect (Study 2), and life satisfaction (Study 3), and marginally higher happiness (Study 2) and self‐esteem (Study 3). No relationship between the need for uniqueness and adjustment was found among non‐marginal immigrants. The adaptive value of the need for uniqueness for marginal immigrants is discussed.
Fishing for jaws in early vertebrate evolution: a new hypothesis of mandibular confinement
Authors: Miyashita Tetsuto 
Published: April 2015

ABSTRACTThe evolutionary origin of the vertebrate jaw persists as a deeply puzzling mystery. More than 99% of living vertebrates have jaws, but the evolutionary sequence that ultimately gave rise to this highly successful innovation remains controversial. A synthesis of recent fossil and embryological findings offers a novel solution to this enduring puzzle. The Mandibular Confinement Hypothesis proposes that the jaw evolvedviaspatial confinement of the mandibular arch (the most anterior pharyngeal arch within which the jaw arose). Fossil and anatomical evidence reveals: (i) the mandibular region was initially extensive and distinct among the pharyngeal arches; and (ii) with spatial confinement, the mandibular arch acquired a common pharyngeal pattern only at the origin of the jaw. The confinement occurredviaa shift of a domain boundary that restricted the space the mesenchymal cells of the mandibular arch could occupy. As the surrounding domains replaced mandibular structures at the periphery, this shift allowed neural crest cells and mesodermal mesenchyme of the mandibular arch to acquire patterning programs that operate in the more posterior arches. The mesenchymal population within the mandibular arch was therefore no longer required to differentiate into specialized feeding and ventilation structures, and was remodelled into a jaw. Embryological evidence corroborates that the mandibular arch must be spatially confined for a jaw to develop. This new interpretation suggests neural crest as a key facilitator in correlating elements of the classically recognized vertebrate head ‘segmentation’.

Published: April 2015

AbstractUnderstanding the effect of changing stress conditions on multiphase flow in porous media is of fundamental importance for many subsurface activities including enhanced oil recovery, water drawdown from aquifers, soil confinement, and geologic carbon storage. Geomechanical properties of complex porous systems are dynamically linked to flow conditions, but their feedback relationship is often oversimplified due to the difficulty of representing pore‐scale stress deformation and multiphase flow characteristics in high fidelity. In this work, we performed pore‐scale experiments of single‐ and multiphase flow through bead packs at different confining pressure conditions to elucidate compaction‐dependent characteristics of granular packs and their impact on fluid flow. A series of drainage and imbibition cycles were conducted on a water‐wet, soda‐lime glass bead pack under varying confining stress conditions. Simultaneously, X‐ray micro‐CT was used to visualize and quantify the degree of deformation and fluid distribution corresponding with each stress condition and injection cycle. Micro‐CT images were segmented using a gradient‐based method to identify fluids (e.g., oil and water), and solid phase redistribution throughout the different experimental stages. Changes in porosity, tortuosity, and specific surface area were quantified as a function of applied confining pressure. Results demonstrate varying degrees of sensitivity of these properties to confining pressure, which suggests that caution must be taken when considering scalability of these properties for practical modeling purposes. Changes in capillary number with confining pressure are attributed to the increase in pore velocity as a result of pore contraction. However, this increase in pore velocity was found to have a marginal impact on average phase trapping at different confining pressures.
Is there a relation between religiosity and customer loyalty in the Chinese context?
Authors: Tang Gui , Li Dong 
Published: April 2015

AbstractThe prevalent and complicated religiosity inside Chinese consumer makes it interesting but difficult to investigate the relation between their religiosity and consumer behaviour. Based on the marketing and psychology background in the Chinese context, this study explored the relationship between Chinese religiosity and their customer loyalty. Cross‐sectional survey data and statistical methods were used to compare customer loyalty under different levels of religiosity. The results reveal significant and positive differences of customer loyalty among consumers with different extent of religiosity in most product categories. This study puts forward a new perspective for marketers to predict and develop loyal customers, even to promote marketing segmentation and customer value.
Corporate sustainability: perception and response by older consumers
Authors: Stolz Johannes , Bautista Rafael 
Published: April 2015

AbstractThis study empirically investigates the importance of environmental sustainability in the decision‐making of older consumers when purchasing consumer goods. Moreover, their perception of corporate sustainability is analyzed. Applying an online survey, effects are measured separately among German (n = 486) and Spanish (n = 503) respondents. By dividing the respondents in young (18–34 years), middle‐aged (35–49 years) and older people (>50 years), we particularly examine the cohort of older respondents. By the use of structural equation modeling, the impact of perceived corporate sustainability on the consumer's effort to act sustainably is evaluated to derive a better understanding in the Spanish and German market on how to address the concerns of the steadily increasing segment of older consumers. Even though price and brand of consumer goods play a significant role in the purchase decisions of the older respondents, our findings emphasize a considerable interest in the environmental impact of their purchases. Perceived price and quality of the sustainable products offer leads them to act in an environmentally sustainable manner.
Association of physicochemical with technological properties of wheat
Authors: Banu Iuliana , Aprodu Iuliana 
Published: April 2015

SummaryThis study focused on twenty‐five different European common wheat varieties and aimed to identify correlations between the most important quality characteristics. When considering the physicochemical characteristics of the wheat samples, our results indicated that milling value is not correlated with vitreous kernel and test weight, but is correlated with gliadin/glutenin. The technological properties of the whole‐wheat flours estimated by means of Mixolab indicated rather good protein quality and the ability to form doughs with good stability in case of most of the samples. Technological behaviour of the flour was affected by dietary fibres and pentosan contents. The starch behaviour was positively correlated with the pentosan contents. The principal components analysis allowed establishing correlations between physicochemical, technological and nutritional parameters of wheat varieties. This finding is important for efficient selecting among wheat varieties, especially when healthy cereal‐based foods are desired.
Towards an understanding of the role of business intelligence systems in organisational knowing
Authors: Shollo Arisa , Galliers Robert D. 
Published: April 2015

AbstractRecent advances in information technology (IT), such as the advent of business intelligence (BI) systems, have increased the ability of organisations to collect and analyse data to support decisions. There is little focus to date, however, on how BI systems might play a role in organisational knowledge creation – in organisational knowing. We develop a conceptual framework of organisational knowing based on a synthesis of the literature, and use this as a framework to investigate how BI systems facilitate knowing in a case organisation. We identify two practices triggered by BI systems that distinguish them from prior applications of IT: the ability to initiate problem articulation and dialogue, and that of data selection (e.g. to address information needs of organisational decision makers at different managerial levels). This study provides empirical evidence of the performative outcome of BI systems in relation to organisational knowing through the practices of articulation and data selection. It provides a practice perspective on BI and focuses on the role of BI systems in organisational knowing thereby opening up a new departure for BI research that considers the implications of BI systems in organisations with actual practice in mind.

Published: April 2015

AbstractPurposeTo assess dietary and nutritional changes among the elderly following pros‐thodontic rehabilitation. Another objective was to study the relationship, if any, between diet and nutrition, with extent of edentulism and different types of prosthodontic treatment.Materials and MethodsOne hundred and thirty‐five patients who satisfied the inclu‐sion and exclusion criteria and agreed to be a part of the study after informed consent were recruited to this longitudinal study. Following selection, they were investigated on four aspects: dental examination, dietary assessment, anthropometric assessment, and serum biochemical assessment. All measurements were collected twice, first at baseline and then 6 months following prosthodontic rehabilitation. Treatment modalities included were complete denture (CD), removable partial denture (RPD), and fixed partial denture (FPD). The RPD group was of two types: distal extension prosthesis (RPDD) and tooth‐supported prosthesis (RPDT). Change (post‐pre) in outcome measures was compared by one‐way ANOVA, and significance of mean difference between the groups was done by Tukey's honestly significance difference post hoc test.ResultsThe improvement in diet was found to be: CD > RPDD > RPDT > FPD. Significant improvement in weight (p < 0.001), BMI (p < 0.001), protein (p < 0.001), carbohydrate (p = 0.021), calorie (p < 0.001), iron (p = 0.002), and vitamin B (p < 0.001) in group CD as compared to partially edentulous patients (group RPDD + RPDT + FPD) was noted. The protein and calorie intake increased significantly in group RPD as compared to group FPD in partially edentulous patients.ConclusionProsthetic rehabilitation becomes increasingly important as the level of edentulism increases to improve dietary, anthropometric, and biochemical parameters.
