Authors: Mutlu Bulent , Paudel Ashok , Ileri Cigdem , Atas Halil , Yildizeli Bedrettin , Kepez Alper 
Published: June 2016

Background Our aim was to determine the prevalence of coronary artery − pulmonary artery collaterals in patients with chronic thromboembolic pulmonary hypertension (CTEPH) by retrospectively evaluating coronary angiograms of eligible consecutive patients who had undergone pulmonary endarterectomy (PEA). We also aimed to evaluate predictors and potential clinical associates of these collaterals.
Methods Coronary angiograms of 83 consecutive CTEPH patients who had undergone coronary angiography before PEA operation between January 1, 2012 and June 1, 2015 were retrospectively evaluated for presence of coronary artery − pulmonary artery collaterals. Medical records of all patients were also retrospectively reviewed for demographic information, cardiovascular risk factors, preoperative right heart catheterization reports, operation reports, and follow-up data. Data of CTEPH patients with coronary artery − pulmonary artery collaterals were compared with data of CTEPH patients without such collaterals.
Results There were 15 patients (18.1%) with definite and 4 patients (4.8%) with probable coronary artery − pulmonary artery collaterals among the study population. CTEPH patients with collaterals had higher preoperative pulmonary artery pressures, higher pulmonary vascular resistance (PVR) and lower cardiac index values compared with CTEPH patients without collaterals. However, CTEPH patients with collaterals displayed higher amount of reduction in PVR after PEA compared with patients without collaterals. There were no significant differences between groups regarding incidence of reperfusion injury or mortality.
Conclusion Prevalence of coronary artery − pulmonary artery collaterals seems to be increased in our CTEPH patients compared with the general population. The presence of coronary artery − pulmonary artery collaterals is often combined with proximal disease with the possibility of increased reduction of PVR after PEA operation.
Reduction in Spring Flow Threatens Rio Grande Silvery Minnow: Trends in Abundance during River Intermittency
Authors: Archdeacon Thomas P. 
Published: June 2016

AbstractHabitat fragmentation and changes in flow regime can structure fish assemblages, resulting in extirpations or invasions. A guild of freshwater stream fishes that spawn semi‐buoyant, nonadhesive eggs directly in the water column are particularly susceptible to extirpation in fragmented streams. The pelagic broadcast‐spawning Rio Grande Silvery Minnow Hybognathus amarus was listed as endangered in 1994 and has been intensely managed since. I used mean May flows and the number of times the channel dried within a year to predict numbers of Rio Grande Silvery Minnow captured in isolated pools in the Middle Rio Grande, New Mexico. Adult Rio Grande Silvery Minnow numbers increased as previous year's mean May discharge increased, and generally decreased with each subsequent drying event. Similarly, numbers of young‐of‐year Rio Grande Silvery Minnow increased with increasing mean May discharge in the current year. However, young‐of‐year minnow were either very abundant or nearly absent in isolated pools, depending on mean May discharge. Overall trends show a strong decrease in total yearly numbers of adult and young‐of‐year Rio Grande Silvery Minnow collected in isolated pools from 2009 to 2014, coupled with an increase in the proportion of hatchery‐reared adults. Overall numbers fell from >1,000/km in 2009 to <15/km in 2014. Hatchery‐reared fish increased from 0% in 2009 collections to 90% in 2014 collections. Managers should focus recovery efforts on providing spring flows that improve recruitment, and avoiding consecutive years of low spring flow because any population recovery will likely be negated by three consecutive years of recruitment failure. A self‐sustaining population of Rio Grande Silvery Minnow is unlikely without management options that mitigate the effects of multiyear droughts.Received August 3, 2015; accepted February 12, 2016 Published online June 21, 2016
Fish and Blue Crab Density along a Riprap‐Sill‐Hardened Shoreline: Comparisons with Spartina Marsh and Riprap
Authors: Balouskus Richard G. , Targett Timothy E. 
Published: June 2016

AbstractWetland managers have historically considered riprap‐sill structures (a type of “living shoreline” consisting of a rock sill that is placed low in the intertidal zone, with native vegetation planted between the sill and the shore) to be more ecologically sound than the riprap that is traditionally applied for shoreline stabilization in estuaries. However, little research has been conducted to compare the macrofauna associated with riprap‐sill and riprap‐hardened shorelines. Density and diversity of fish and blue crabs Callinectes sapidus were compared via weekly sampling along a riprap‐sill shoreline, a riprap shoreline, and a shoreline fringed with smooth cordgrass Spartina alterniflora marsh in the Delaware Coastal Bays during summer 2010. Seining was conducted to quantitatively sample the shore zone and shallow subtidal regions, and minnow traps were used to determine the presence or absence of fishes in the mid‐ to upper‐intertidal zone of each shoreline type. Temporally persistent differences in macrofaunal density and diversity were evident among the three shoreline types. In terms of fish density and diversity metrics, riprap‐sill was more similar to the smooth cordgrass shoreline than to the traditional riprap shoreline. These results provide evidence for the biological advantage of riprap‐sill over traditional riprap as a shoreline modification structure; spatial confirmation by further studies at different locations is warranted.Received October 27, 2015; accepted March 15, 2016 Published online June 21, 2016
ACE: adaptive cluster expansion for maximum entropy graphical model inference
Authors: Barton J. P. , De Leonardis E. , Coucke A. , Cocco S. 
Published: June 2016

Abstract
Motivation: Graphical models are often employed to interpret patterns of correlations observed in data through a network of interactions between the variables. Recently, Ising/Potts models, also known as Markov random fields, have been productively applied to diverse problems in biology, including the prediction of structural contacts from protein sequence data and the description of neural activity patterns. However, inference of such models is a challenging computational problem that cannot be solved exactly. Here, we describe the adaptive cluster expansion (ACE) method to quickly and accurately infer Ising or Potts models based on correlation data. ACE avoids overfitting by constructing a sparse network of interactions sufficient to reproduce the observed correlation data within the statistical error expected due to finite sampling. When convergence of the ACE algorithm is slow, we combine it with a Boltzmann Machine Learning algorithm (BML). We illustrate this method on a variety of biological and artificial datasets and compare it to state-of-the-art approximate methods such as Gaussian and pseudo-likelihood inference.
Results: We show that ACE accurately reproduces the true parameters of the underlying model when they are known, and yields accurate statistical descriptions of both biological and artificial data. Models inferred by ACE more accurately describe the statistics of the data, including both the constrained low-order correlations and unconstrained higher-order correlations, compared to those obtained by faster Gaussian and pseudo-likelihood methods. These alternative approaches can recover the structure of the interaction network but typically not the correct strength of interactions, resulting in less accurate generative models.

The positive effects of population-based preferential sampling in environmental epidemiology
Authors: Antonelli Joseph , Cefalu Matthew , Bornn Luke 
Published: June 2016

Summary
In environmental epidemiology, exposures are not always available at subject locations and must be predicted using monitoring data. The monitor locations are often outside the control of researchers, and previous studies have shown that “preferential sampling” of monitoring locations can adversely affect exposure prediction and subsequent health effect estimation. We adopt a slightly different definition of preferential sampling than is typically seen in the literature, which we call population-based preferential sampling. Population-based preferential sampling occurs when the location of the monitors is dependent on the subject locations. We show the impact that population-based preferential sampling has on exposure prediction and health effect estimation using analytic results and a simulation study. A simple, one-parameter model is proposed to measure the degree to which monitors are preferentially sampled with respect to population density. We then discuss these concepts in the context of PM2.5 and the EPA Air Quality System monitoring sites, which are generally placed in areas of higher population density to capture the population's exposure.

Published: June 2016

AbstractGene set enrichment analysis (GSEA) is an ubiquitously used tool for evaluating pathway enrichment in transcriptional data. Typical experimental design consists in comparing two conditions with several replicates using a differential gene expression test followed by preranked GSEA performed against a collection of hundreds and thousands of pathways. However, the reference implementation of this method cannot accurately estimate small P-values, which significantly limits its sensitivity due to multiple hypotheses correction procedure.Here we present FGSEA (Fast Gene Set Enrichment Analysis) method that is able to estimate arbitrarily low GSEA P-values with a high accuracy in a matter of minutes or even seconds. To confirm the accuracy of the method, we also developed an exact algorithm for GSEA P-values calculation for integer gene-level statistics. Using the exact algorithm as a reference we show that FGSEA is able to routinely estimate P-values up to 10−100with a small and predictable estimation error. We systematically evaluate FGSEA on a collection of 605 datasets and show that FGSEA recovers much more statistically significant pathways compared to other implementations.FGSEA is open source and available as an R package in Bioconductor (http://bioconductor.org/packages/fgsea/) and on GitHub (https://github.com/ctlab/fgsea/).
The risk and return of farm real estate and the “bad data problem”
Authors: Kuethe Todd 
Published: June 2016

Purpose– The purpose of this paper is to explore the consequences of appraisal smoothing in the estimation of the risks and returns of farm real estate. It examines the degree to which the risk and return characteristics of farm real estate are an artifact of the methods used to measure aggregate property values.Design/methodology/approach– A multifactor asset pricing model is estimated using farm real estate returns in a manner consistent with prior research, as well as using farm real estate returns calculated using two synthetic unsmoothing procedures developed in the real estate finance literature.Findings– The model suggests that unsmoothed farm real estate returns exhibit characteristics that differ from those suggested by prior research. The unsmoothed returns suggest a stronger correlation with economy wide investment risks.Originality/value– This is the first study to evaluate the impacts of appraisal smoothing in a farm real estate context. It provides a simple framework for addressing many of the pricing anomalies associated with farmland.

Published: June 2016

Purpose
– This paper is based on a crop insurance implementation currently undergoing in Haiti. The purpose of this paper is to present the development of a program tailored to rice production in the Artibonite Valley, the challenges and opportunities that are arising from the exercise as well as pitfalls and ways to avoid them.

Design/methodology/approach
– The Système de Financement et d’Assurances Agricoles en Haïti’s approach for the development of crop insurance is in accordance with 13 concepts considered essential in the implementation of agricultural insurance programs. The case study is presented through each of these 13 fundamental concepts.

Findings
– The paper provides an insight on challenges any organization will face when implementing crop insurance for smallholder farmers. It points out notably that close collaboration of executing agencies with local partners is essential from data collection through insurance development and delivery and that all participants should receive a specific training tailored to their level of education and understanding.

Social implications
– Haiti is one of the poorest countries on the planet. Smallholder farmers could benefit a lot from crop insurance. It could help them stabilize their income when facing crop losses due to natural hazards or uncontrollable natural events.

Originality/value
– This paper fulfills an identified need to share real case studies exposing challenges faced when implementing crop insurance for smallholder farmers.

Graduate and Post-graduate.

Case overview
The Future Group is the most profitable retailer in India without having any foreign direct investment (FDI). In September 2013, the retailer launched its online retailing platform, “Big Bazaar Direct” (BBD). BBD is a franchisee-based model which aims to partner with people having rich customer networks to reach more shoppers. This novice idea of BBD is the result of Big Bazaar’s greater mind share over its market share. Mr Kishore Biyani, CEO Future Group, has lot of expectation from this business model.

Expected learning outcomes
The outcomes include: to familiarize students with Indian Retail Industry; to develop student’s skills in critically analyzing an online retail-based new business model; and to explain key factors that work for success of a retail-based business model.

Corruption in Russia: IKEA’s expansion to the East (A-D)
Authors: Müller Urs 
Published: June 2016

Subject area
Business ethics corruption governance and compliance integrity management international management intercultural and cross-cultural management internationalization corporate social responsibility (CSR).

Study level/applicability
The case has successfully been used with a wide range of audiences from masters/MBAs to Executives. It will also work with undergraduates.

Case overview
This four-part case series can be used to discuss business ethics, compliance/governance, integrity management, reacting to and preparing against corruption in the context of internationalization and allows to also briefly touching upon the issue of CSR. Case (A) describes a challenge IKEA was facing, while trying to enter Russia in 2000. The company was preparing to open its first flagship store on the outskirts of Moscow, only the first of several planned projects. After substantial investments in infrastructure and logistics, IKEA focused on marketing, but quickly faced a sudden complication. Its major ad campaign in the Moscow Metro with the slogan “[e]very 10th European was made in one of our beds” was labeled “tasteless”. IKEA had to stop the campaign because it “couldn’t prove” the claim. Soon Lennart Dahlgren, the first general manager of IKEA in Russia must have realized that the unsuccessful ad campaign was going to be the least of his problems: A few weeks before the planned opening, the local utility company decided not to provide their services for the store if IKEA did not pay a bribe. What should IKEA and Lennart Dahlgren do? Was there any alternative to playing the game the Russian way, and paying? The subsequent cases (B), (C) and (D) describe IKEA’s creative response to the challenges described in case (A), and then report about new challenges with alleged corruption within IKEA and in the legal environment, and finally raise the question whether IKEA can be considered to have a (corporate social) responsibility to fight corruption on a societal level to build the platform for its own operation in Russia.

Expected learning outcomes
Responding to a threatening corruption demand (here: responding to an outside demand for a bribe), avoiding corruption from the outside, cross-cultural differences in drawing the line for corruption, preventing corruption within the organization, (corporate social) responsibility of firms to improve the political/legal/social/moral environment in which they operate are the expected learning outcomes.

Teacher discourse supporting peer collaboration in mathematics
Authors: Yamaji Akane 
Published: June 2016

Purpose– The purpose of this paper is to focus on a two-year lesson study by a teacher exploring peer collaboration and examines a teacher’s discourse that might generate a mathematical participation structure in which students needing help are likely to participate.Design/methodology/approach– A math class conducted by a teacher in a Tokyo secondary school was observed for two years. The teacher’s questions in whole-class discussions were analyzed quantitatively and qualitatively. Then, the teacher received feedback and retrospectively wrote his viewpoint or concerns.Findings– The following features of the teacher’s questions were observed: no bias in any questions; various questions soon after group discussion, including easy expression of unstructured thoughts; and a consistent view of learning, such as not ending learning despite having received answers. These features were not fixed strategies, but one end of the reflective trajectory in considering the relation between students’ growth and lessons’ mathematical content. Possibly, this reflective cycle might support participate structure in which students learn collaboratively.Originality/value– Long-term observation and spending time with one class enabled the researcher to investigate lesson study systematically and showed the significance of teachers and researchers studying together.
The role of approach and avoidance motivation in employee voice
Authors: Ma Chao 
Published: June 2016

Purpose
– The purpose of this paper is to develop a model of the processes through which approach and avoidance motivation influence constructive and defensive voice behavior, with the moderating role of workplace ostracism and contingent self-esteem.

Design/methodology/approach
– The paper is conceptual and quantitative study should be conducted to explore the propositions proposed in this paper.

Findings
– This paper proposes that approach motivation is positively related to constructive voice while avoidance motivation is positively related to defensive voice. In addition, workplace ostracism and contingent self-esteem/importance of performance to self-esteem (IPSE) are examined as two moderators of the motivation-voice behavior relationship.

Practical implications
– By understanding employees’ different motives underpinning the voice behavior explained in this paper, it may be easier for management to take measures to facilitate constructive voice and abate defensive voice. Organizations may wish to formulate policies and regulations and to foster a climate to prevent ostracism from happening. Programs designed to develop employees with high IPSE may be implemented.

Originality/value
– Most of empirical work on voice has focussed on employee voice behaviors with positive attributes. This paper adopts approach and avoidance motivation as two antecedents, and grounded in self-regulation theory, exploring both positive and negative types of voice behavior. This paper also examines how negative interpersonal behavior such as ostracism affects voice behavior, and provide insights on upside of contingent self-esteem.
Satisfaction of learning, performance, and relatedness needs at work and employees’ organizational identification
Authors: Kumar Manish , Jauhari Hemang 
Published: June 2016

Purpose– In today’s scenario when loyalty can no longer be demanded from employees, the extent of organizational identification (OID) of employees predicts outcomes of organizational interest. It is therefore essential for organizations to foster the sense of oneness in employees. Since, need satisfaction lies at the core of human motivation, the purpose of this paper is to test if satisfaction of learning, performance, and relatedness needs at workplace could influence employees’ identification with the organization.Design/methodology/approach– For this study, the authors collected data from 365 professionals representing diverse work backgrounds and analysed it using structural equation modelling approach.Findings– Results suggest that OID is positively influenced by satisfaction of these three needs and about 45 per cent of its variance is explained by these needs.Originality/value– The study corroborates the relevance of the three needs in organizational context. Although not a part of design of the study, nonetheless the study sheds light on methodological and theoretical possibilities of salience of needs. Therefore to the best of awareness, this study stands apart from other studies exploring relationship of disparate needs with OID. The authors believe the study enriches social identity theory literature in indicating that researchers should not only consider focusing on relationship of needs variables with OID but also the dynamics of interaction between various needs among themselves as well as on their differential relationship with OID.
