Hierarchical power and personality in leader-member exchange
Authors: Yoon David J. , Bono Joyce E. 
Published: September 2016

PurposeThe purpose of this paper is to examine the role of supervisor and subordinate personality in high quality supervisor-subordinate (leader-member exchange; LMX) relationships.Design/methodology/approachIn this field study, 142 supervisors drawn from a leadership development program, and 509 of their subordinates, completed a personality survey and reported on the quality of their relationships.FindingsSelf and partner personality (agreeableness and extraversion), and the match between them were predictors of LMX. Consistent with approach/inhibition theory of power, personality traits of relationship partners had a stronger effect when the partner held a position of power (i.e. supervisors) than when the partner was a subordinate.Practical implicationsThe results inform organizational selection by showing the importance of supervisory traits for the formation of high quality supervisor-subordinate relationships. They may also help organizations facilitate the development of high quality supervisory relationships. The findings also suggest that it is critical to consider the balance of power when assessing LMX, along with factors that lead to its development, or benefits that ensue from it.Originality/valueTo date, there is an assumption that certain traits predict the development of high quality relationships between supervisors and subordinates. The results point out the importance of considering the role of power in LMX relationships. The paper shows that the effects of supervisory traits, which are rarely examined in the context of LMX relationships, more strongly predict LMX than do the traits of subordinates.
Yes, we complain … so what?
Authors: Aubé Caroline , Rousseau Vincent 
Published: September 2016

PurposeThe purpose of this paper is to theorize and test a model concerning the role of complaining behaviors in work teams. Despite the prevalence of workplace complaining, there is no consensus in the literature regarding the consequences of those behaviors and the extent to which they are harmful.Design/methodology/approachUsing a multisource approach and a team-level design, the authors collected data from 82 teams (i.e. 394 members and their 82 immediate superiors) working in a Canadian public safety organization.FindingsThe results show that complaining behaviors are negatively related to two effectiveness outcomes (i.e. team performance and team process improvement) and that meaningfulness mediates these relationships. The results also reveal that task interdependence moderates the relationship between complaining behaviors and meaningfulness. More specifically, complaining behaviors have a stronger relationship with meaningfulness when the level of task interdependence is high.Originality/valueThe present study contributes to the literature on counterproductive behaviors by deepening the understanding of emergent states and outcomes stemming from workplace complaining, particularly in work teams. The findings of this study highlight the negative consequences that complaining behaviors may have in a team setting, the underlying mechanism involved in these relationships, and the moderating role of task interdependence.
Making friends and enemies on social media: the case of gun policy organizations
Authors: Merry Melissa 
Published: September 2016

Purpose
The purpose of this paper is to explore the role of interest groups in the formation of online echo chambers and to determine whether interest groups’ use of social media contributes to political polarization.

Design/methodology/approach
This study used a content analysis of nearly 10,000 tweets (from 2009 to 2014) by the Brady campaign to Prevent Gun Violence and the National Rifle Association to examine how groups engage with their political allies and opponents.

Findings
The results indicated that both groups engaged primarily with their supporters on Twitter while avoiding confrontation with their opponents. In particular, both groups used hashtags designed to reach their supporters, retweeted messages almost exclusively from other users with whom they agreed, and disproportionately used Twitter handles of their allies, while avoiding the use of Twitter handles of their opponents.

Practical implications
The findings suggest that interest groups’ use of social media accelerates the formation of online echo chambers, but does not lead to an increase in polarization beyond existing levels, given practices that maintain civility between opposing sides.

Originality/value
This is one of few studies to examine the role of interest groups in the formation of online echo chambers. It also uses a novel approach – the examination of both the interactions that occur among social media users and those that are explicitly avoided.
Coherent campaigns? Campaign broadcast and social messaging
Authors: Bode Leticia , Lassen David S. , Kim Young Mie , Shah Dhavan V. , Fowler Erika Franklin , Ridout Travis , Franz Michael 
Published: September 2016

Purpose
Despite the growing use of social media by politicians, especially during election campaigns, research on the integration of these media into broader campaign communication strategies remains rare. The purpose of this paper is to ask what the consequences of the transition to social media may be, specifically considering how Senate candidates’ use of a popular social network, Twitter, is related to their messaging via broadcast media in the form of campaign advertising, in terms of content and tone.

Design/methodology/approach
To address this research question, a unique data set combining every tweet (10,303) and every television ad aired (576,933 ad airings) by candidate campaigns for the US Senate during the 2010 campaign is created. Using these data, tweets and ads are analyzed for their references to issues as well as their overall tone.

Findings
Findings demonstrate that social messaging often resembles broadcast advertising, but that Twitter nonetheless occupies a unique place in modern campaigns in that its tone tends to be quite different than that of advertisements.

Research limitations/implications
This sheds light on a larger debate about whether online campaigning has produced a fundamental change in election practices or whether new media simply extend “campaigning as usual.”

Originality/value
This study uses a novel data set, encompassing the complete universe of ads and tweets distributed by candidates for Senate in 2010.

Authors: Schroeder Eileen E. , Zarinnia E. Anne 
Published: September 2016

Purpose
This paper aims to describe the conversations and collaborative problem-solving strategies initiated by a small group of faculty working collegially across five University of Wisconsin–Whitewater (UW) campuses to address the state shortage of school librarians.

Design/methodology/approach
This is a case study of the development of the consortium; its curriculum design and redesign and course development based on Conversation Theory, a set of common principles; and new directions in the library field.

Findings
This consortium developed a virtual department structure and a curriculum that has addressed the needs of the state and overcome bureaucratic hurdles.

Originality/value
The structure of the consortium; the use of the Conversation Theory to guide its development, curriculum and course design; and solutions to problems that arose could benefit other collaborative efforts.
Marine transient electromagnetic sounding of deep buried hydrocarbon reservoirs: principles, methodologies and limitations
Authors: Barsukov Pavel O. , Fainberg Edward B. 
Published: September 2016

ABSTRACTThe possibility of a time‐domain electromagnetic sounding method using excitation and measurement of vertical electric fields to search for and identify deeply buried reservoirs of hydrocarbons offshore is investigated. The method operates on source–receiver offsets, which are several times less than the depth of the reservoir. Geoelectric information is obtained from the transient responses recorded in the pauses between the pulses of electric current in the absence of the source field. The basics of the method, as well as its sensitivity, resolution, and the highest accessible depth of soundings for various geological conditions in a wide range of sea depths, are analyzed. For the analysis, 1D and 3D geoelectric models of hydrocarbon reservoirs are used. It is shown that under existing technologies of excitation and measurement of vertical electric fields, the highest accessible depth of soundings can be up to 4 km. Technology for the inversion and interpretation of transient responses is demonstrated on experimental data.
Review of research grant allocation to psychosocial studies in diabetes research
Authors: Jones A. , Vallis M. , Cooke D. , Pouwer F. 
Published: September 2016

AbstractAimsTo estimate and discuss the allocation of diabetes research funds to studies with a psychosocial focus.MethodsAnnual reports and funded‐research databases from approximately the last 5 years (if available) were reviewed from the following representative funding organizations, the American Diabetes Association, the Canadian Diabetes Association, Diabetes Australia, Diabetes UK, the Dutch Diabetes Research Foundation and the European Foundation for the Study of Diabetes, in order to estimate the overall proportion of studies allocated research funding that had a psychosocial focus.ResultsAn estimated mean of 8% of funded studies from our sample were found to have a psychosocial focus.ConclusionsThe proportion of funded studies with a psychosocial focus was small, with an estimated mean ratio of 17:1 observed between funded biomedical and psychosocial studies in diabetes research. While several factors may account for this finding, the observation that 90% of funded studies are biomedical may be partly attributable to the methodological orthodoxy of applying biomedical reductionism to understand and treat disease. A more comprehensive and systemic whole‐person approach in diabetes research that resembles more closely the complexity of human beings is needed and may lead to improved care for individuals living with diabetes or at risk of diabetes.

Published: September 2016

AbstractAimTo investigate the safety and efficacy of insulin degludec/liraglutide (IDegLira), a novel combination product, as add‐on therapy for people with Type 2 diabetes uncontrolled on sulphonylurea therapy.MethodsIn this 26‐week, double‐blind trial, adults with Type 2 diabetes [HbA1c 53–75 mmol/mol (7.0–9.0%)] were randomized to IDegLira (n = 289) or placebo (n = 146) as add‐on to pre‐trial sulphonylurea ± metformin, titrating to a fasting glycaemic target of 4.0–6.0 mmol/l. Treatment initiation was at 10 dose steps, and maximum dose was 50 dose steps (50 units insulin degludec/1.8 mg liraglutide).ResultsThe mean HbA1c decreased from 63 mmol/mol (7.9%) to 46 mmol/mol (6.4%) with IDegLira and to 57 mmol/mol (7.4%) with placebo [estimated treatment difference –11 mmol/mol (95% CI –13; –10) or –1.02% (95% CI –1.18; –0.87); P < 0.001]. The HbA1c target of 53 mmol/mol (<7%) was achieved by 79.2% of participants in the IDegLira group vs 28.8% in the placebo group [estimated odds ratio 11.95 (95% CI 7.22; 19.77); P < 0.001]. Mean weight change was +0.5 kg with IDegLira vs –1.0 kg with placebo [estimated treatment difference 1.48 kg (95% CI 0.90; 2.06); P < 0.001]. Confirmed hypoglycaemia occurred in 41.7 and 17.1% of IDegLira‐ and placebo‐treated participants, respectively, with rates of 3.5 vs 1.4 events/patient‐years of exposure [estimated rate ratio 3.74 (95% CI 2.28; 6.13); P < 0.001]. IDegLira was generally well tolerated. The rates of serious adverse events were 20.3 and 8.0 per 100 patient‐years of exposure with IDegLira and placebo, respectively, without obvious patterns in the type of events.ConclusionsIDegLira can be used in people uncontrolled with sulphonylurea ± metformin to improve efficacy with a safety profile in line with previous DUAL trials.
Issues that support the creation of ICT workarounds: towards a theoretical understanding of feral information systems
Authors: Spierings Anthony , Kerr Don , Houghton Luke 
Published: September 2016

Abstractenterprise system (ES) software is often supplemented independently by end users who develop personal solutions that establish connections between the required business practices and the ES. One solution is a type of information and communications technology workaround, a feral information system (FIS) – defined as a workaround designed to achieve certain requirements by using any information technology tool that an end user uses in conjunction with, or instead of, the mandated information system. To explore this, we conducted a case study at a large utility company. We conclude that feral information systems are not a behavioural deviance. FISs are by‐products of end users seeking operational efficiency, namely, to nullify additional transactional costs imposed by the ES. Our findings suggest that end users of ES will fall into one of four modes of operation: mode 1, where end users submit to the ES; mode 2, where they dismiss the ES; mode 3, where they develop an FIS that remains hidden from the ES proponents; and mode 4, where they operate the FIS in open defiance of the ES proponents. In this research, we deliberately take the practitioner view and, therefore, outline how different pressures help to create an FIS as a response to a poorly mandated ES. We also make a theoretical contribution by exploring issues that lead to workarounds and suggest that future research into these modes of operation can be theorized in future proposed studies.
A two‐stage forecasting approach for short‐term intermodal freight prediction
Authors: Moscoso‐López José Antonio , Turias Ignacio , Jiménez‐Come Maria Jesús , Ruiz‐Aguilar Juan Jesús , Cerbán María del Mar 
Published: September 2016

AbstractThe forecasting of the freight transportation, especially the short‐term case, is an important topic in the daily supply chain management. Intermodal freight transportation is subject to multiple complex calendar effects arising in the port environment. The use of prediction methods provides information that may be helpful as a decision‐making tool in the management and planning of operations processes in ports. This work addresses the forecasting problem on a daily basis by a novel two‐stage scheme combination to offer reliable predictions of fresh freight weight on Ro‐Ro (roll‐on/roll‐off) transport for 7 and 14 days ahead. The study compares daily forecasting with a weekly forecasting approach. The applies database preprocessing and Bayesian regularization neural networks (BRNN) in Stage I. In Stage II, an ensemble framework of the best BRNN models is used to enhance the Stage I forecasting. The results show that the models assessed are a promising tool to predict freight time series for Ro‐Ro transport.
TRADE SIZE CLUSTERING IN THE E‐MINI INDEX FUTURES MARKETS
Authors: Wang Qin , Zhang Jun 
Published: September 2016

AbstractWe compare trade size clustering of morning, afternoon, and after‐hours trades in both the E‐mini S&P 500 and E‐mini NASDAQ‐100 futures markets. Morning and afternoon volatility is higher than after‐hours volatility. Morning and afternoon trades cluster more at round sizes than do after‐hours trades, and morning and afternoon trades cluster more on days with macroeconomic announcements than without announcements. Taken together, our results are consistent with the prior literature that trade size clustering increases with volatility.
LOST IN TRANSLATION: WHICH STOCK PRICES BEAR THE BURDEN TO ADJUST TO EXCHANGE RATES?
Authors: Lockwood Jimmy , Lockwood Larry , Lau Sie Ting 
Published: September 2016

AbstractWe examine the role of competing exchanges to restore price parity following currency shocks during 2008, a year characterized by dramatic currency volatility. Burdens on the NYSE and home market to restore price parity for cross‐listed stocks are more dynamic than previously thought. Adjustments in NYSE prices are not uniform across stocks, are often less than home market adjustments, and are strongly influenced by differences in order execution quality. We quantify the effect of currency shocks using a three‐system error correction model, and show that currency shocks exert independent and profound effects as prices gravitate to restore price parity.
RANKINGS AND TRENDS IN FINANCE PUBLISHING: AN ITERATIVE APPROACH
Authors: Crook Matthew D. , Walkup Brian R. 
Published: September 2016

AbstractUsing a sample of 20 finance journals from 1985 to 2014, we develop a robust, iterative loop ranking system for journals, universities, and doctoral programs across five‐year intervals. Unlike past models, our dynamic model requires minimal reliance on external rankings. New journals create an immediate impact on rankings, likely because they attract high‐profile authors in early issues. Niche journals rank higher than broad‐based journals outside the top five. Our results demonstrate increased productivity of international universities and nonacademic institutions relative to U.S. universities. International doctoral programs experience similar increases in graduate productivity. Over time, collaboration between authors at different institutions increases.
The role of two branched‐chain amino acid transporters in Staphylococcus aureus growth, membrane fatty acid composition and virulence
Authors: Kaiser Julienne C. , Sen Suranjana , Sinha Anshul , Wilkinson Brian J. , Heinrichs David E. 
Published: September 2016

SummaryThe branched‐chain amino acids (BCAAs) are vital to both growth and virulence of the human pathogen Staphylococcus aureus. In addition to supporting protein synthesis, the BCAAs serve as precursors for branched‐chain fatty acids (BCFAs), which are predominant membrane fatty acids, and, in association with the global regulatory protein CodY, the BCAAs are key co‐regulators of virulence factors. Despite these critical functions, S. aureus represses Leu and Val synthesis, instead preferring to acquire them from the extracellular milieu. We previously identified BrnQ1 as a BCAA transporter, yet a brnQ1 mutant remained capable of BCAA acquisition. Here, we describe BcaP as an additional BCAA transporter, and determine that it plays a secondary role to BrnQ1 during S. aureus growth in a chemically defined medium. Furthermore, membrane fatty acid composition analysis revealed that BrnQ1, and not BcaP, is required for transporting Leu and Val to be used for iso‐BCFA synthesis. Despite a predominant role for BrnQ1 in vitro, both BrnQ1 and BcaP are required for S. aureus fitness in vivo in a hematogenous spread infection model and a nasal colonisation model. These data demonstrate the importance of BrnQ1 and BcaP for growth, environmental adaptation and virulence of S. aureus.

Published: September 2016

PurposeWe aimed to identify a combined prognostic factor for predicting better performance in risk stratification.Materials and MethodsWe reviewed the clinical and pathological variables of 316 patients with oral squamous cell carcinoma (OSCC) who underwent surgery. To identify a combined predictor, principal component analysis (PCA) was performed.ResultsUnivariate analysis showed that the independent prognostic variables for overall survival (OS) were pathologic T stage (T1 vs T4, HR = 1.99, 95% CI: = 1.083–3.675, P = 0.026) and pathologic N stage (N0 vs N2, HR=1.90, 95% CI: = 1.17–3.08, P = 0.008). In the multivariate analysis, only pathologic T stage was significant (P = 0.006 and P = 0.007); however, the multivariate model was not significant (P = 0.191). The multivariate model became significant by including lymph node ratio (LNR) instead of pathologic N stage (P = 0.0025 in numeric LNR, P = 0.0007 in categorized LNR). Also, the performance of prediction model was improved by a combined prognostic factor (P = 0.0002).ConclusionsThe newly identified combined prognostic factor included resection margin, differentiation, and LNR, and they were insignificant factors independently except for LNR. This combined prognostic factor showed a good performance although it did not include molecular markers; therefore, it may be used conveniently for risk stratification of patients with OSCC by combining only clinical information.
A robust, high‐throughput method for computing maize ear, cob, and kernel attributes automatically from images

Published: September 2016

SummaryGrain yield of the maize plant depends on the sizes, shapes, and numbers of ears and the kernels they bear. An automated pipeline that can measure these components of yield from easily‐obtained digital images is needed to advance our understanding of this globally important crop. Here we present three custom algorithms designed to compute such yield components automatically from digital images acquired by a low‐cost platform. One algorithm determines the average space each kernel occupies along the cob axis using a sliding‐window Fourier transform analysis of image intensity features. A second counts individual kernels removed from ears, including those in clusters. A third measures each kernel's major and minor axis after a Bayesian analysis of contour points identifies the kernel tip. Dimensionless ear and kernel shape traits that may interrelate yield components are measured by principal components analysis of contour point sets. Increased objectivity and speed compared to typical manual methods are achieved without loss of accuracy as evidenced by high correlations with ground truth measurements and simulated data. Millimeter‐scale differences among ear, cob, and kernel traits that ranged more than 2.5‐fold across a diverse group of inbred maize lines were resolved. This system for measuring maize ear, cob, and kernel attributes is being used by multiple research groups as an automated Web service running on community high‐throughput computing and distributed data storage infrastructure. Users may create their own workflow using the source code that is staged for download on a public repository.
Por fuera del esencialismo. Dispositivos desidentificadores en Clarice Lispector y Nicola Constantino
Authors: Herrero Mariela 
Published: September 2016

<p>El presente artículo propone un análisis comparativo entre dos objetos estéticos provenientes de diferentes disciplinas artísticas. El objetivo del mismo está orientado a dar cuenta de cierta expansión o desborde que estos objetos experimentan en la búsqueda y el intento por cuestionar la noción de frontera disciplinar y especificidad del medio, entendido como algo estático y acabado. Se trata de rastrear de qué modo estos gestos, que se enmarcan en el contexto más amplio y complejo del arte contemporáneo latinoamericano, exceden los límites del arte y se exhiben como objetos mutantes, en fluctuación constante, problematizando la categoría de obra y conduciendo a una desidentificación de los soportes y los materiales con que estas son producidas. </p>
