Investigating leader-member exchange and employee envy: An evidence from the information technology industry
Authors: Nandedkar Ankur 
Published: May 2018

AbstractThis study investigates the dynamics of supervisor-subordinate relationship, commonly referred in leadership literature as leader-member exchange (LMX), in the context of envy, and its associated consequences. Building on the affective events theory, we hypothesize that employees who do not share a good relationship with their supervisors (low-quality LMX) will be envious of the peers that maintain great relationship (high-quality LMX) with the supervisor. As a result, they will restrict knowledge sharing, and engage in uncivil behaviors. Hierarchical regression was used to test hypotheses on data derived from a sample of 204 software engineers working across various information technology firms in India. The study found support for all of the proposed hypotheses and extends research in the field by demonstrating negative consequences of envy in the workplace.
Eli-Twist sewing thread – an alternative to conventional thread
Authors: Regar Madan Lal , Sinha Sujit Kumar , Choubisa Bhavna 
Published: May 2018

Purpose
Sewing thread plays an important role in transforming a two-dimensional fabric into three-dimensional garment. Over the years, ring spinning has been dominating the yarn market because of its consistent performance. Eli-Twist spinning system, a new method of yarn manufacture, provides a product with improved mechanical and physical properties than the conventional ring-spun yarn. It is the process of producing a two-ply compact yarn with improved fibre utilisation. The purpose of this paper is to assess the feasibility of using Eli-Twist yarn as a sewing thread and to compare its performance with conventional thread.

Design/methodology/approach
In this study, regular polyester and Indian cotton were used to produce the Eli-Twist and conventional TFO thread. Three different blends (100 per cent polyester, 50/50 polyester/cotton [P/C] and 100 per cent cotton) were taken to produce three different counts (39.4 tex, 29.5 tex and 23.6 tex) from each composition. The hairiness, tenacity, breaking elongation and coefficient of yarn-to-metal friction of threads were tested and a comparative analysis was made. The seam performance of all the threads was judged by seam strength, seam efficiency and seam elongation.

Findings
The results show that the mass irregularity and imperfections are more or less similar for both types of threads. Eli-Twist sewing thread has shown less friction, less hairiness and higher tensile strength. The Eli-Twist sewing thread was found to be better than the conventional two-ply sewing thread. The seam performance parameters, such as seam strength, seam efficiency and seam elongation of the Eli-Twist thread showed significantly improved performance.

Originality/value
The main concern of this study is delineating the performance of the Eli-Twist sewing thread. No study in this regard has been reported so far. The improved physical and mechanical behaviour of the Eli-Twist yarn has prompted to assess its performance as sewing thread.
Mapping information literacy using the Business Research Competencies
Authors: Howard Heather A. , Wood Nora , Stonebraker Ilana 
Published: May 2018

Purpose
Librarians in higher education have adopted curriculum mapping in an effort to determine where effective information literacy instruction can help fill gaps in the curriculum and prepare students for both coursework and future research demands. While curriculum mapping has been used widely across academia, few studies have considered business curriculum and the development of information literacy instruction. This paper aims to provide an overview of the current landscape of curriculum mapping across business courses at two institutions and a replicable methodology for other institutions.

Design/methodology/approach
In this paper, the authors will examine two case studies at large research universities that evaluate curriculum mapping against the BRASS Business Research Competencies at the undergraduate and the graduate business levels.

Findings
This study found that the Business Research Competencies are a valid method to evaluate in both case studies. Curriculum mapping also uncovered various gaps in business education across the curricula at both institutions and led to open discussions with faculty in an effort to improve the success of students both during their degree programs and into their careers.

Originality/value
This study provides a framework and methodology for evaluating business curriculums against robust standards to improve student success. With examples from undergraduate and graduate programs, the results of this project promise to have long-lasting implications on the development of curriculums across business programs, including the value of librarian support in developing Business Research Competencies.
Personal values and value congruence of public administration graduate students: An exploratory study in China
Authors: Zhong Wei , Bao Yuanjie 
Published: May 2018

AbstractExplorations on the value profiles of current and prospective public organisation employees in China are scarce. The current study investigates this critical issue. Data were collected via a questionnaire from graduate students enrolled in a school of public administration in China. The sample consisted of both full‐time students who were prepared to pursue their careers in public organisations upon graduation, and part‐time students who were mostly public organisation employees. Multivariate analyses of covariance (MANCOVAs) and analyses of covariance (ANCOVAs) were used for data analysis. The results show that there are consistent value preferences among all students, and some noteworthy patterns in the relationship between value profiles and demographic and work‐related features. The results also shed light on whether a unique value set could differentiate various types of organisations, and demonstrate that employees in the core public service perceive higher level of value congruence than those in parapublic sectors. These findings provide implications and insights for the management practices in public organisations.

Published: May 2018

AbstractA flow‐injection analysis tandem mass spectrometry (FIA MSMS) method was developed for rapid quantitative analysis of 10 different inorganic and organic explosives. Performance is optimized by tailoring the ionization method (APCI/ESI), de‐clustering potentials, and collision energies for each specific analyte. In doing so, a single instrument can be used to detect urea nitrate, potassium chlorate, 2,4,6‐trinitrotoluene, 2,4,6‐trinitrophenylmethylnitramine, triacetone triperoxide, hexamethylene triperoxide diamine, pentaerythritol tetranitrate, 1,3,5‐trinitroperhydro‐1,3,5‐triazine, nitroglycerin, and octohy‐dro‐1,3,5,7‐tetranitro‐1,3,5,7‐tetrazocine with sensitivities all in the picogram per milliliter range. In conclusion, FIA APCI/ESI MSMS is a fast (<1 min/sample), sensitive (~pg/mL LOQ), and precise (intraday RSD < 10%) method for trace explosive detection that can play an important role in criminal and attributional forensics, counterterrorism, and environmental protection areas, and has the potential to augment or replace several of the existing explosive detection methods.
The price of protection: a defensive endosymbiont impairs nymph growth in the bird cherry‐oat aphid, Rhopalosiphum padi

Published: May 2018

AbstractBacterial endosymbionts have enabled aphids to adapt to a range of stressors, but their effects in many aphid species remain to be established. The bird cherry‐oat aphid, Rhopalosiphum padi (Linnaeus), is an important pest of cereals worldwide and has been reported to form symbiotic associations with Serratia symbiotica and Sitobion miscanthi L‐type symbiont endobacteria, although the resulting aphid phenotype has not been described. This study presents the first report of R. padi infection with the facultative bacterial endosymbiont Hamiltonella defensa. Individuals of R. padi were sampled from populations in Eastern Scotland, UK, and shown to represent seven R. padi genotypes based on the size of polymorphic microsatellite markers; two of these genotypes harbored H. defensa. In parasitism assays, survival of H. defensa‐infected nymphs following attack by the parasitoid wasp Aphidius colemani (Viereck) was 5 fold higher than for uninfected nymphs. Aphid genotype was a major determinant of aphid performance on two Hordeum species, a modern cultivar of barley H. vulgare and a wild relative H. spontaneum, although aphids infected with H. defensa showed 16% lower nymph mass gain on the partially resistant wild relative compared with uninfected individuals. These findings suggest that deploying resistance traits in barley will favor the fittest R. padi genotypes, but symbiont‐infected individuals will be favored when parasitoids are abundant, although these aphids will not achieve optimal performance on a poor quality host plant.
CEO risk‐taking incentives and relative performance evaluation
Authors: Black Dirk E. 
Published: May 2018

AbstractThis paper examines how changes in CEO risk‐taking incentives are associated with changes in the use of relative performance evaluation (RPE) in CEO contracts. Using a shock to the accounting for executive stock options (FAS 123R), I confirm that risk‐taking incentives and option grants declined following FAS 123R using a within‐firm design, but not a within‐CEO‐firm design. Decreased risk‐taking incentives lead executives to invest in projects with lower systematic risk and can result in reduced incentives to hedge exposure to systematic risk in CEO compensation contracts via RPE. However, CEO relative risk aversion increases with decreases in risk‐taking incentives, potentially increasing incentives to protect CEO wealth from systematic performance via RPE. Testing these competing predictions, I find modest evidence consistent with reduced RPE surrounding FAS 123R, suggesting that when CEO risk‐taking incentives are reduced, so are incentives to shield CEO pay from systematic performance.

SummaryCompromised eggshell quality causes considerable economic losses for the egg industry. Breeding for improved eggshell quality has been very challenging. Eggshell quality is a trait that would greatly benefit from marker‐assisted selection, which would allow the selection of sires for their direct contribution to the trait and would also allow implementation of measurements integrating a number of shell parameters that are difficult to measure. In this study, we selected the most promising autosomal quantitative trait loci (QTL) affecting eggshell quality on chromosomes 2, 3, 6 and 14 from earlier experiments and we extended the F2 population to include 1599 F2 females. The study was repeated on two commercial populations: Lohmann Tierzucht Rhode Island Red line (n = 692 females) and a Hy‐Line White Plymouth Rock line (n = 290 progeny tested males). We analyzed the selected autosomal QTL regions on the three populations with SNP markers at 4–13 SNPs/Mb density. QTL for eggshell quality were replicated on all studied regions in the F2 population. New QTL were detected for eggshell color on chromosomes 3 and 6. Marker associations with eggshell quality traits were validated in the tested commercial lines on chromosomes 2, 3 and 6, thus paving the way for marker‐assisted selection for improved eggshell quality.
Influence of maternal obesity on Bishop Score and failed induction of labour: A retrospective cohort study in a regional tertiary centre
Authors: Little Jessica , Nugent Rachael , Vangaveti Venkat 
Published: May 2018

BackgroundMaternal obesity is a growing health concern that has previously been associated with increased need for induction of labour (IOL) and caesarean section (CS) rates. Currently, limited evidence explores the influence of maternal body mass index (BMI) on Bishop Score (BS) and outcome of IOL. This study hypothesises that maternal obesity will lead to a lower BS at presentation, higher rates of failed IOL, and increased CS rates.AimsTo explore the influence of maternal obesity on BS and likelihood of failed IOL.MethodsA retrospective cohort analysis was conducted of all live, term, singleton, cephalic deliveries initiated with IOL across normal BMI (18.00–24.99), overweight BMI (25.00–29.99), and obese BMI (>30.00) at the Townsville Hospital and Health Service (THHS) between July 2011 to June 2016. Student’s t‐test, χ2 test, and binary logistic regression were used for statistical analysis. BS and failed IOL, defined as CS with cervical dilatation <3 cm, were the primary outcome measures. Delivery mode was the secondary outcome measure.ResultsA total of 1543 women were included, 678 with normal BMI, 370 with overweight BMI, and 495 with obese BMI. Obese women are more likely to have a low BS (<5) at presentation (unadjusted odds ratio (OR) 1.5 (1.1–2.0), P < 0.05), an increased rate of failed IOL (adjusted OR (aOR) 1.6 (1.0–2.5), P < 0.05) and increased CS rate (aOR 1.1 (1.0–1.9), P < 0.05), compared to normal weight women.ConclusionsMaternal obesity is associated with a lower BS, more difficult IOL process, and increased risk of failed IOL and CS.
Evolution of the central West Greenland margin and the Nuussuaq Basin: Localised basin uplift along a stable continental margin proposed from thermochronological data
Authors: Jess Scott , Stephenson Randell , Brown Roderick 
Published: May 2018

AbstractThe Late Cenozoic is typically considered a time of widespread episodic tectonic uplift along the West Greenland continental margin (36–2 Ma), similar to other margins across the North Atlantic, such as Norway, East Greenland and the UK. The present study re‐examines and remodels onshore thermochronological data from central West Greenland and the Cretaceous Nuussuaq Basin, utilising a Bayesian modelling approach and new concepts related to radiation damage within apatite. These new thermal histories indicate that slow‐protracted cooling has occurred across the southern extent of the margin during the Mesozoic and Cenozoic, whereas those from within the Nuussuaq Basin display reheating through the Late Cretaceous/Palaeogene and cooling to present. Results suggest that no significant Late Cenozoic uplift has occurred along the southern margin, while cooling in the Nuussuaq Basin is consistent with events outlined in the basin's stratigraphy and implies uplift during volcanism and an isostatic response to the unroofing of the lithosphere has elevated the modern topography. These results imply significant tectonism in the region ceased by ~45 Ma, yet have wider implications regarding how low temperature thermochronology data are treated and our understanding of the postrift evolution of passive margins.

AbstractAimsTo investigate depolarization and repolarization durations in people with Type 1 diabetes, including the relationship to age.Methods855 persons with Type 1 diabetes without known heart disease were included and matched with 1710 participants from a general population study. Clinical examinations, questionnaires and biochemistry were assessed. A 10‐second 12‐lead ECG was performed and analysed digitally.ResultsQTc was longer in people with Type 1 diabetes compared to controls (414±16 vs. 411±19 ms, P <0.001), and particularly so in young people with Type 1 diabetes. The fully adjusted increase was 13.8 ms (95% confidence interval (CI): 8.6–19.0 ms, P <0.001) at age 20 years and 3.4 ms (CI: 1.5–5.3 ms, P<0.001) at age 40 years. The rate‐corrected QRSc was increased in people with Type 1 diabetes (97±11 vs. 95±11 ms, P <0.001) and was age‐independent (P =0.5). JTc was increased in the young people with Type 1 diabetes (10.7 ms (CI: 5.4–16.0 ms, P <0.001) at age 20 years), but not in older people with Type 1 diabetes (interaction age‐diabetes, P <0.01).ConclusionsFor people with Type 1 diabetes, cardiac depolarization is increased at all ages, whereas repolarization is increased only relatively in young people with Type 1 diabetes. Hence, young people with Type 1 diabetes may be more prone to ventricular arrhythmias. The findings contribute to the understanding of sudden cardiac death in young people with Type 1 diabetes.
No further improvement in pregnancy‐related outcomes in the offspring of mothers with pre‐gestational diabetes in Bavaria, Germany, between 2001 and 2016
Authors: Beyerlein A. , Lack N. , von Kries R. 
Published: May 2018

AbstractAimsTo investigate whether there has been further improvement in the risk of adverse outcomes in pregnancies in women with diabetes during 2008–2016 in Bavaria, Germany.MethodsUsing cross‐sectional data on all 1716 170 deliveries in Bavarian hospitals between 2001 and 2016, we assessed the risks of stillbirth, early neonatal death, preterm delivery, large for gestational age, malformations, low Apgar score and low umbilical cord pH by maternal group with diabetes (gestational, pre‐gestational, or none) separately for 2001–2007 and 2008–2016. We also investigated the associations of specific risk factors such as maternal smoking with respect to early mortality and malformations in each group with diabetes during 2008–2016.ResultsNo further reduction in the risk for any adverse outcome in mothers with pre‐gestational diabetes and their offspring during 2008–2016 was observed. Maternal smoking, multiple delivery and substandard antenatal care were the strongest additional predictors of both early perinatal mortality and malformations for mothers with pre‐gestational diabetes. The respective risks were lower and also decreased over time for mothers with gestational diabetes.ConclusionsNo significant improvement has been achieved in the management of pregnancies affected by pre‐gestational diabetes during the last decade. The apparent risk reductions in women with gestational diabetes may partly be due to a change in diagnostic criteria over time. Women with pre‐gestational diabetes who smoke, carry more than one child, or are not regularly seen during pregnancy, may need particular attention.
Vertical stratification of scolytine beetles in temperate forests
Authors: Procházka Jiří , Cizek Lukas , Schlaghamerský Jiří 
Published: May 2018

AbstractAlthough most studies exploring the vertical distribution of arthropods in forests have been limited to discrete comparisons between understorey and canopy, few have sampled across multiple heights.We studied vertical distribution of scolytine beetle flight activity in temperate lowland broadleaf and montane beech‐fir forests using flight interception traps arranged in vertical transects with traps placed 0.4, 1.2, 7, 14, and 21 m above ground. In each forest type 15 vertical transects (75 traps) were used.The assemblages sampled at 0.4 and 1.2 m above ground (undergrowth) clearly differed from those at 7, 14, and 21 m (midstorey and canopy).Ambrosia‐fungi feeder abundance peaked at 1.2 m in the mountains, whereas in the lowland they were almost evenly distributed from 1.2 to 21 m. Phloem feeders were significantly more abundant in the midstorey and canopy than in the undergrowth.Height preferences of eleven species were identified. Four species were associated with traps exposed at 7, 14, or 21 m, whereas seven species were associated with the height of 1.2 m. No species was associated with the 0.4 m height.To cover entire scolytine assemblages of forest stands, sampling should thus not be restricted to the usually sampled understorey level, but also cover the canopy.
Exploitation of lettuce waste flour to increase bread functionality: effect on physical, nutritional, sensory properties and on consumer response
Authors: Plazzotta Stella , Sillani Sandro , Manzocco Lara 
Published: May 2018

SummaryPhenol and fibre‐rich flour obtained by air‐drying and grinding of lettuce waste was partially substituted (26, 53, 170 and 575 g kg−1) to wheat flour to produce functional bread. The addition of flour progressively decreased dough leavening capacity while increased bread moisture and firmness. Lettuce waste flour significantly increased the polyphenolic content (up to 3.4 g GAE kg−1) of bread samples and enhanced their antioxidant activity by 200%. Bread containing 170 and 575 g kg−1 of lettuce waste flour presented sensory properties and consumer acceptability comparable to those of commercial wholemeal bread with similar rye bran content. Bread containing at least 170 g kg−1 of lettuce waste flour could be associated to nutritional claims related to its enhanced fibre content (>30 g kg−1). Data obtained by conjoint analysis demonstrate the possibility of increasing consumer preference for lettuce waste flour bread by proper nutritional (fibre content) and sustainability (lettuce waste valorisation) claims.

OBJECTIVESTo evaluate physicians' views on advance care planning, goals of care, and end‐of‐life conversations.DESIGNRandom sample telephone survey.SETTINGUnited States.PARTICIPANTSPhysicians (primary care specialists; pulmonology, cardiology, oncology subspecialists) actively practicing medicine and regularly seeing patients aged 65 and older (N=736; 81% male, 75% white, 66% aged ≥50.MEASUREMENTSA 37‐item telephone survey constructed by a professional polling group with national expert oversight measured attitudes and perceptions of barriers and facilitators to advance care planning. Summative data are presented here.RESULTSNinety‐nine percent of participants agreed that it is important to have end‐of‐life conversations, yet only 29% reported that they have formal training for such conversations. Those most likely to have training included younger physicians and those caring for a racially and ethnically diverse population. Patient values and preferences were the strongest motivating factors in having advance care planning conversations, with 92% of participants rating it extremely important. Ninety‐five percent of participants reported that they supported a new Medicare fee‐for‐service benefit reimbursing advance care planning. The biggest barrier mentioned was time availability. Other barriers included not wanting a patient to give up hope and feeling uncomfortable.CONCLUSIONWith more than half of physicians reporting that they feel educationally unprepared, there medical school curricula need to be strengthened to ensure readiness for end‐of‐life conversations. Clinician barriers need to be addressed to meet the needs of older adults and families. Policies that focus on payment for quality should be evaluated at regular intervals to monitor their effect on advance care planning.
