Authors: Lau Patrick W. C. , Wong Del P. , Ngo Jake K. , Liang Y. , Kim C. G. , Kim H. S. 
Published: July 2014

AbstractThis study examined the effects of a 6‐week intermittent exercise training, at different intensities, on body composition, functional walking and aerobic endurance in overweight children. Forty‐eight overweight children (age: 10.4 ± 0.9 years) were randomly assigned to either intervention or control group. Lower and higher intensity intermittent exercise groups (LIIE and HIIE) performed intermittent running three times a week. LIIE performed more intervals at a lower intensity [16 intervals at 100% of individual maximal aerobic speed (MAS), 8 minutes in total], and HIIE performed fewer intervals at a higher intensity (12 intervals at 120% of MAS, 6 minutes in total). Each interval consisted of a 15‐second run at the required speed, followed by a 15‐second passive recovery. After 6 weeks, HIIE had a significantly (p < 0.05) higher percentage reduction in sum of skinfolds (i.e. calf and triceps), and significantly (p < 0.05) fewer steps during the functional obstacle performance, as compared with LIIE and control group. Significant improvement (p < 0.05) was found in intermittent aerobic endurance for HIIE as compared to the control group. Higher intensity intermittent training is an effective and time‐efficient intervention for improving body composition, functional walking and aerobic endurance in overweight children.
repfdr: a tool for replicability analysis for genome-wide association studies
Authors: Heller Ruth , Yaacoby Shay , Yekutieli Daniel 
Published: July 2014

Abstract
Motivation: Identification of single nucleotide polymorphisms that are associated with a phenotype in more than one study is of great scientific interest in the genome-wide association studies (GWAS) research. The empirical Bayes approach for discovering whether results have been replicated across studies was shown to be a reliable method, and close to optimal in terms of power.
Results: The R package repfdr provides a flexible implementation of the empirical Bayes approach for replicability analysis and meta-analysis, to be used when several studies examine the same set of null hypotheses. The usefulness of the package for the GWAS community is discussed.
Availability and implementation: The R package repfdr can be downloaded from CRAN.

Solar system chemical abundances corrected for systematics
Authors: Gonzalez Guillermo 
Published: July 2014

Abstract
The relative chemical abundances between CI meteorites and the solar photosphere exhibit a significant trend with condensation temperature. A trend with condensation temperature is also seen when the solar photospheric abundances are compared to those of nearby solar twins. We use both these trends to determine the alteration of the elemental abundances of the meteorites and the photosphere by fractionation and calculate a new set of primordial Solar system abundances.

Authors: Ravelli Alberto , Villanacci Vincenzo , Cadei Moris , Fuoti Maurizio , Gennati Giada , Salemme Marianna 
Published: July 2014

ABSTRACTObjectives:Dilated intercellular spaces (DIS) in the esophageal epithelium can be induced by acid and reduced by proton pump inhibitors (PPI), and are thus considered a marker of gastroesophageal reflux disease (GERD). Over the years, however, DIS have also been reported in esophagitis unrelated to GERD. Because DIS have never been formally measured in eosinophilic esophagitis (EoE), we aimed at detecting and measuring DIS in EoE before and after nutritional or pharmacological therapy.Methods:In 22 children with EoE, DIS were measured by morphometry and transmission electron microscopy (TEM), before and after treatment with topical steroids (n = 16) and/or exclusion diet (n = 13). A total of 30 children undergoing upper gastrointestinal endoscopy with biopsy for nonesophageal disorders acted as controls.Results:In controls, the mean (±standard deviation [SD]) number of esophageal eosinophils was 0.91 (±0.47) and the mean DIS values were 0.62 (±0.08) μm at morphometry and 0.33 (±0.24) μm at TEM. In patients with EoE, the mean (±SD) number of esophageal eosinophils decreased from 31.8 (±6.96) to 6.64 (±5.01) (P < 0.0001), and the mean DIS values decreased from 2.26 (±0.21) to 1.23 (±0.20) μm at morphometry (P < 0.0001), and from 2.24 (±0.28) to 0.98 (±0.19) μm at TEM (P < 0.0001), respectively, before and after treatment.Conclusions:DIS are a prominent morphological feature of EoE, in which they can be significantly reduced by an appropriate non‐PPI therapy.
IL‐6 572 C/G, 190 C/T, and 174 G/C Gene Polymorphisms in Children's Malnutrition
Authors: Marginean Cristina O. , Banescu Claudia , Voidazan Septimiu , Duicu Carmen 
Published: July 2014

ABSTRACTObjectives:The aim of the present study was to establish the correlations between the polymorphisms of the genes interleukin‐6 (IL‐6) 572, 190, and 174 in children's malnutrition.Methods:We assessed 283 hospitalized children and divided them into 2 groups: group I (control) included 110 patients with normal nutritional status, median (range) age 10.90 (1–18) years; and group II consisted of 173 malnourished patients, median (range) age 10.70 (1–18) years.Results:The 2 groups underwent IL‐6 572 cytosine allele (C)/guanine allele (G), 190 C/thymine allele (T), and 174 G/C polymorphism testing, measurement of anthropometric indicators (mid‐upper arm circumference and tricipital skinfold thickness [TST]), and paraclinical evaluation (protein, albumin). We observed that the GG and CG genotypes were more frequent in malnourished children for the IL‐6 174 gene (P = 0.0001), whereas the CT heterozygous genotype was more frequent in the malnourished group for the IL‐6 190 gene (P = 0.003). Body mass index (BMI), middle upper arm circumference (MUAC), TST, and low serum albumin levels correlated with the GG and CG genotypes of the IL‐6 572 and IL‐6 174 genes, and with the CT genotype of the IL‐6 190 gene, in children with malnutrition, whereas the IL‐6 190 TT genotype was a protective factor for malnutrition (P = 0.0001).Conclusions:Malnutrition is more frequently associated in children with IL‐6 174 G allele carriers (GG and CG genotypes), whereas IL‐6 190 TT genotype has a protective function. In malnourished children, the IL‐6 572/190/174 GG/CT/CG, GG/CT/GG, GG/CC/GG, and GG/CC/CG combined genotypes are more frequent.
Utility of Gastrointestinal Fluoroscopic Studies in Detecting Stricture After Neonatal Necrotizing Enterocolitis
Authors: Wiland Emily L. , South Andrew P. , Kraus Steven J. , Meinzen‐Derr Jareen 
Published: July 2014

ABSTRACTObjectives:We report our institution's 5‐year experience with upper gastrointestinal study with small bowel follow‐through (UGI‐SBFT) and contrast enema (CE) for the diagnosis of a post–necrotizing enterocolitis (NEC) stricture. We hypothesized that sensitivity and specificity of UGI‐SBFT and CE were <85% in diagnosing a post‐NEC stricture.Methods:A retrospective observational cohort study was performed. Included patients were neonates diagnosed as having Bell's modified stage 2 or 3 NEC who had undergone UGI‐SBFT and/or CE to evaluate for a stricture. Exploratory laparotomy was used to definitively determine the stricture presence, which was confirmed by pathology. An infant was categorized as having no stricture if no surgical intervention occurred or if no stricture was reported on pathology following surgical resection.Results:A total of 56 patients met inclusion criteria, with 51 UGI‐SBFT and 85 CE performed. A total of 25 patients were diagnosed as having a stricture. For small bowel (SB) strictures, CE compared with UGI‐SBFT has a higher sensitivity (0.667 vs 0.00) and a similar specificity (0.857 vs 0.833). For SB and/or colonic strictures, CE has a sensitivity of 0.667 and a specificity of 0.951. Strictures were more likely to be found on imaging in symptomatic infants compared with those in asymptomatic infants (28% vs 8%, P = 0.002).Conclusions:CE should be the initial study in the diagnostic workup for a post‐NEC stricture because this test has a higher likelihood of detecting a stricture if it is present. As a result of low sensitivity of UGI‐SBFT and/or CE in the diagnosis of a post‐NEC stricture, a negative study should not rule out the diagnosis of a stricture in persistently symptomatic patients.

ABSTRACTObjectives:This European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) position statement provides a comprehensive guide for health care providers to manage percutaneous endoscopic gastrostomy tubes in a safe, effective, and appropriate way.Methods:Relevant literature from searches of PubMed, CINAHL, and recent guidelines was reviewed. In the absence of evidence, recommendations reflect the expert opinion of the authors. Final consensus was obtained by multiple e‐mail exchange and during 3 face‐to‐face meetings of the gastroenterology committee of the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition.Results:Endoscopically placed gastrostomy devices are essential in the management of children with feeding and nutritional problems. The article focuses on practical issues such as indications and contraindications.Conclusions:The decision to place an endoscopic gastrostomy has to be made by an appropriate multidisciplinary team, which then provides active follow‐up and care for the child and the device.
Intergenerational recruiting: the impact of sales job candidate perception of interviewer age
Authors: Allen Concha , Schetzsle Stacey , L. Mallin Michael , Bolman Pullins Ellen 
Published: July 2014

Purpose
– The purpose of this paper is to determine the effects from perceptions of age disadvantageness when job candidates are interviewing with recruiters from different age groups. More specifically, the authors examine the issues of intergenerational recruiting through the lens of social identity theory (SIT) and relational demography. Using these theoretical underpinnings, problems that result from dissatisfaction with between group inequities in the recruiting process are explored.

Design/methodology/approach
– Using these theoretical underpinnings, problems that result from dissatisfaction with between group inequities in the recruiting process are explored. Results from a survey of 176 undergraduate students actively pursuing sales positions provide evidence that candidate perceptions are influenced by age of the interviewer.

Findings
– The results support that sales job candidates do indeed feel disadvantaged when interviewed by older recruiters. Compared to interviewers from a more similar age in-group interviewer, the respondents felt a greater difficulty in establishing commonality and credibility and they felt the need to establish dependability, demonstrate professionalism, energy, and enthusiasm with an older out-group interviewer. Interestingly, sales job candidates did not feel lower levels of job confidence relative to the age-group of the interviewer.

Research limitations/implications
– The study reflects the perceptions of sales job applicants sampled from only two universities in the same region of the USA. Generalizations outside of this job applicant population (i.e. major and geography) cannot be made based on this limited group of respondents. Additionally, outcomes were not explored in this paper, so there is no way to know with certainty that these feelings of disadvantageness translate to concrete differences in results, such as lower job acceptance.

Practical implications
– From a recruiting/hiring managers’ perspective, they should be mindful that younger sales job candidates may feel uncomfortable or disadvantaged relative to age/generational differences. This could potentially even impact a recruit's desire to consider a company and accept a job offer, based on perceived organizational cultural differences. Educators need to prepare college students for the interview process. They should make students aware that they may feel the need to compensate for feelings that stem from intergeneration differences.

Originality/value
– From a theory perspective, the study applies the SIT to a human resource and recruiting context to better understand possible recruiting barriers that may be particularly relevant in today's changing recruitment environment. This represents one of only a few empirical research efforts that has attempted to explain intergenerational recruiting issues relative to SIT. In addition to the use of SIT and relational demography, this paper introduces a unique context.
Feeling dissimilar and helping others? A conceptual analysis
Authors: Yung Chou Shih , Chang Tree , Han Bo 
Published: July 2014

Purpose
– The purpose of this paper is to explore how perceived visible, work value, and informational dissimilarity affect an individual's helping behavior. Additionally, it investigates the moderating roles of the need for affiliation and need for achievement.

Design/methodology/approach
– A theoretical analysis was performed.

Findings
– It is proposed that perceived visible, work value, and informational dissimilarity will have a negative impact on an individual's helping behavior. Additionally, it is posited that the need for affiliation and need for achievement will positively moderate the negative relationship between perceived dissimilarity and helping behavior.

Research limitations/implications
– This paper provides additional insight into antecedents of helping behavior, and offers a theoretical basis for future research that examines the relationship between subjective diversity and discretionary behaviors in organizations.

Practical implications
– This paper has several important implications. First, managers are recommended to implement effective educational approaches, such as role-playing, that help eliminate employees’ negative perceptions of dissimilarity and promote willingness to help co-workers. Second, managers should reinforce shared vision, values, and goals, which in turn may encourage interpersonal cooperative behaviors. Third, managers should facilitate the dissemination of knowledge and information that are crucial to individual performance. Fourth, managers are encouraged to provide employees with trainings on effective interpersonal processes such as inclusion and emotional management. Finally, managers should increase the degree of task interdependence, which may promote high levels of helping behavior.

Originality/value
– This paper is one of the very few studies that link helping behavior with subjective perceptions of dissimilarity. More importantly, this paper highlights the importance of the interaction between dissimilarity perceptions and internal driving forces.
The impact of users’ verbal/imagery cognitive styles on their Web search behavior
Authors: Hariri Nadjla , Asadi Maryam , Mansourian Yazdan 
Published: July 2014

Purpose
– The purpose of this paper is to investigate the effects of verbal-imagery cognitive styles of information searching behavior of users in using the Web.

Design/methodology/approach
– In all, 44 participants were recruited for this study. The participants’ cognitive styles were measured by using Riding's Cognitive Style Analysis test. Three search tasks were designed based on Kim's search task definitions. Moreover, an individual lab session was arranged and then participants’ memos were analyzed using content analysis.

Findings
– In all, 48 strategies in four categories of behaviors in searching the Web were identified. There were associations between users’ cognitive styles and their information searching behavior. The participants’ selection of the search initiation behaviors varied, so that imagers suffered from more varied initial behavior than verbalizers. The verbalizers tended to search in a narrow area, then broadening the area and following structured navigation and reading behavior to process information, while imagers tended to search in a general area, then narrowing down the search and adopting mixed navigational styles and mixed behaviors to process information. This study revealed that there was a difference in search performance of verbalizers and imagers descriptively, as verbalizers spent more time compared to imagers and imagers visited more nodes than verbalizers for the tasks completion. In addition, the task was an important variable influencing the search performance. Based on the key findings (search initiation behaviors, formulating search queries, navigational behaviors, information processing behaviors), a conceptual pattern of Web searching and cognitive styles is presented.

Research limitations/implications
– The study provides a new understanding of Web users’ information search behavior based on cognitive styles which contributes to the theoretical basis of Web search research. It also raises various questions within the context of user studies

Originality/value
– The paper adopted a mixed approach in the area of information searching on the Web. A valuable contribution lies in the methods developed.
Exploring employee perceptions of Web 2.0 virtual communities from the perspective of knowledge sharing
Authors: Yan Yalan , Zha Xianjin , Yan Ming 
Published: July 2014

Purpose– With the development of Web 2.0 virtual communities, the authors see a useful platform for knowledge sharing. However, knowledge sharing in virtual communities still remains a big challenge given the concern of knowledge quantity and quality. The purpose of this paper is to explore the effect of individual differences on knowledge contributing, knowledge seeking, trust and norm of reciprocity. This study also explores the mean difference between knowledge seeking and knowledge contributing as well as the correlations between knowledge seeking, knowledge contributing, trust and reciprocity so as to provide some guidance for knowledge management practice in China.Design/methodology/approach– Data collected from 430 users of Web 2.0 virtual communities were used for data analysis. The independent samplest-test, one-way analysis of variance (ANOVA), paired samplest-test and correlation analysis were employed.Findings– The independent samplest-test and one-way ANOVA present the effect of individual differences on knowledge contributing, knowledge seeking, trust and norm of reciprocity. The paired samplest-test suggests that employees are more likely to seek knowledge from than contribute knowledge to Web 2.0 virtual communities. The correlation analysis suggests there are positive correlations between knowledge contributing, knowledge seeking, trust and reciprocity.Practical implications– Knowledge management initiatives in Chinese organizations are encountered relatively less frequently, compared with western countries. The authors suggest the findings of this study provide useful insights into the informal knowledge sharing in Web 2.0 virtual communities, which is helpful for guiding knowledge management practice in China.Originality/value– Based on knowledge quantity and knowledge quality whose significance cannot be over-emphasized in virtual communities, this study explores employee perceptions of Web 2.0 virtual communities from the perspective of knowledge sharing, which the authors think provides a new view for knowledge sharing research and practice alike in China.
Intentionality attributions and humiliation
Authors: Varela-Neira Concepción , Vázquez-Casielles Rodolfo , Iglesias Víctor 
Published: July 2014

Purpose
– This paper aims to determine whether intentionality attributions have an effect on the customer’s complaint and switching behavior after a service failure, after accounting for the effects of the traditional dimensions of attribution (stability and controllability), and to examine whether intentionality attributions give rise to humiliation and to what degree this negative emotion enables us to understand the customer’s complaint and switching behavior after a service failure.

Design/methodology/approach
– A contribution of this investigation is that it studies real complaint and switching behaviors, as the few studies that focus on understanding customers’ complaint and defection behaviors mostly analyze customers’ intentions.

Findings
– The results of the study indicate that intentionality attributions have an effect on the customer’s switching behavior after a service failure, in addition to the impact of the traditional dimensions of attribution. The findings also show that humiliation is the emotion that mediates the relationship between intentionality attributions and switching behavior, opposite to other emotions that may also be related to attributions. Finally, the results also support that the effect of attribution of intentionality on complaint behavior is indirect; it only exists because attribution of intentionality influences negative emotions like humiliation, which in turn influences complaint behavior.

Practical implications
– To understand what makes customers complain after a service failure or switch service providers without giving them first the possibility of recovering the failure may help managers reduce the damage caused by the failure and increase the company’s profits.

Originality/value
– This study will try to contribute to the service failure research by analyzing the role of two variables that have not been analyzed before in this context: intentionality attribution and humiliation.
