Contrasting Population Demographics of Invasive Silver Carp between an Impounded and Free-Flowing River
Authors: Stuck Jason G. , Porreca Anthony P. , Wahl David H. , Colombo Robert E. 
Published: February 2015

Abstract
Extensive research has been conducted on Silver Carp Hypopthalmicthys molitrix in the heavily modified Illinois River in the midwestern United States due to the potential for populations to enter the Great Lakes; however, little research has been conducted on populations in unimpounded rivers. The Wabash River is an unimpounded large river in the U.S. Midwest that may be a good model for studying Silver Carp in unregulated river ecosystems that could potentially be invaded if reproducing populations in the Great Lakes are established. In this study we compared population demographics of Silver Carp in the Wabash and Illinois rivers. Abundance was over three times greater in the Illinois than in the Wabash River, although Wabash River Silver Carp had significantly greater mean length, age, and condition and a higher growth rate than did Illinois River Silver Carp. Although the heavily modified and degraded environment in the Illinois River may have aided in the rapid expansion of Silver Carp, intraspecific competition, increased commercial fishing, and competition with native species have likely reduced condition, decreased growth rate, and increased mortality rate of the population. Differences between Silver Carp populations in the Illinois and Wabash rivers suggest that the impacts of invasion may be reduced in ecosystems with little modification.

Published: February 2015

Abstract
We quantified tag retention, survival, and growth in juvenile, captive-reared Humpback Chub Gila cypha marked with three different tag types: (1) Biomark 12.5-mm, 134.2-kHz, full duplex PIT tags injected into the body cavity with a 12-gauge needle; (2) Biomark 8.4-mm, 134.2-kHz, full duplex PIT tags injected with a 16-gauge needle; and (3) Northwest Marine Technology visible implant elastomer (VIE) tags injected under the skin with a 29-gauge needle. Estimates of tag loss, tagging-induced mortality, and growth were evaluated for 60 d with each tag type for four different size-groups of fish: 40–49 mm, 50–59 mm, 60–69 mm, and 70–79 mm TL. Total length was a significant predictor of the probability of PIT tag retention and mortality for both 8-mm and 12-mm PIT tags, and the smallest fish had the highest rates of tag loss (12.5–30.0%) and mortality (7.5–20.0%). Humpback Chub of sizes 40–49 mm TL and tagged with VIE tags had no mortality but did have a 17.5% tag loss. Growth rates of all tagged fish were similar to controls. Our data indicate Humpback Chub can be effectively tagged using either 8-mm or 12-mm PIT tags with little tag loss or mortality at sizes as low as 65 mm TL.

Abstract

Objectives
SMT19969 is a novel antimicrobial under clinical development for the treatment of Clostridium difficile infection (CDI). The objective was to determine the comparative susceptibility of 82 C. difficile clinical isolates (which included ribotype 027 isolates and isolates with reduced metronidazole susceptibility) to SMT19969, fidaxomicin, vancomycin and metronidazole and to determine the killing kinetics and post-antibiotic effects of SMT19969, fidaxomicin and vancomycin against C. difficile.

Methods
MICs were determined by agar incorporation. Killing kinetics and post-antibiotic effects were determined against C. difficile BI1, 630 and 5325 (ribotypes 027, 012 and 078, respectively).

Results
SMT19969 showed potent inhibition of C. difficile (MIC90=0.125 mg/L) and was markedly more active than either metronidazole (MIC90 = 8 mg/L) or vancomycin (MIC90 = 2 mg/L). There were no differences in susceptibility to SMT19969 between different ribotypes. Fidaxomicin was typically one doubling dilution more active than SMT19969 and both agents maintained activity against isolates with reduced susceptibility to metronidazole. In addition, SMT19969 was bactericidal against the C. difficile strains tested, with reductions in viable counts to below the limit of detection by 24 h post-inoculation. Vancomycin was bacteriostatic against all three strains. Fidaxomicin was bactericidal although reduced killing was observed at concentrations &lt;20 × MIC against C. difficile BI1 (ribotype 027) compared with other strains tested.

Conclusions
These data demonstrate that SMT19969 is associated with potent and bactericidal activity against the strains tested and support further investigation of SMT19969 as potential therapy for CDI.

Inhalational Anesthetics Disrupt Postsynaptic Density Protein-95, Drosophila Disc Large Tumor Suppressor, and Zonula Occludens-1 Domain Protein Interactions Critical to Action of Several Excitatory Receptor Channels Related to Anesthesia
Authors: Tao Feng , Chen Qiang , Sato Yuko , Skinner John , Tang Pei , Johns Roger A. 
Published: February 2015

AbstractAbstract
Halothane and isoflurane disrupted PDZ domain–mediated interactions between potassium channel Kv1.4 and GluA2 subunit of AMPA receptor with their respective binding partners. Neither agent affected binding of γ-aminobutyric acid type B receptors with their binding partners. Anesthetics affected binding to PDZ1 and PDZ2 but not PDZ3 domains. Anesthetics interfere with PDZ domain–mediated protein–protein interactions of several receptors that are important to neuronal function.
Supplemental Digital Content is available in the text.

Background:
The authors have shown previously that inhaled anesthetics disrupt the interaction between the second postsynaptic density protein-95, Drosophila disc large tumor suppressor, and zonula occludens-1 (PDZ) domain of postsynaptic density protein-95 (PSD-95) and the C-terminus of N-methyl-d-aspartate receptor subunits NR2A and NR2B. The study data indicate that PDZ domains may serve as a molecular target for inhaled anesthetics. However, the underlying molecular mechanisms remain to be illustrated.

Methods:
Glutathione S-transferase pull-down assay, coimmunoprecipitation, and yeast two-hybrid analysis were used to assess PDZ domain–mediated protein–protein interactions in different conditions. Nuclear magnetic resonance spectroscopy was used to investigate isoflurane-induced chemical shift changes in the PDZ1–3 domains of PSD-95. A surface plasmon resonance–based BIAcore (Sweden) assay was used to examine the ability of isoflurane to inhibit the PDZ domain–mediated protein–protein interactions in real time.

Results:
Halothane and isoflurane dose-dependently inhibited PDZ domain–mediated interactions between PSD-95 and Shaker-type potassium channel Kv1.4 and between α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor subunit GluA2 and its interacting proteins—glutamate receptor–interacting protein or protein interacting with c kinase 1. However, halothane and isoflurane had no effect on PDZ domain–mediated interactions between γ-aminobutyric acid type B receptor and its interacting proteins. The inhaled anesthetic isoflurane mostly affected the residues close to or in the peptide-binding groove of PSD-95 PDZ1 and PDZ2 (especially PDZ2), while barely affecting the peptide-binding groove of PSD-95 PDZ3.

Conclusion:
These results suggest that inhaled anesthetics interfere with PDZ domain–mediated protein–protein interactions at several receptors important to neuronal excitation, anesthesia, and pain processing.
Biliary Atresia
Authors: Feldman Amy G. , Mack Cara L. 
Published: February 2015

ABSTRACTBiliary atresia is a rare disease of unclear etiology, in which obstruction of the biliary tree causes severe cholestasis leading to cirrhosis and ultimately death if left untreated. Biliary atresia is the leading cause of neonatal cholestasis and the most frequent indication for pediatric liver transplantation. Any infant with persistent jaundice beyond 2 weeks of life needs to be evaluated for biliary atresia with fractionation of the bilirubin into conjugated and unconjugated portions. Early performance of a hepatoportoenterostomy in the first 45 days of life to restore bile flow and lessen further damage to the liver is thought to optimize outcome. Despite surgery, progressive liver scarring occurs, and 80% of patients with biliary atresia will require liver transplantation during childhood.
The practice of strategic performance measurement systems
Authors: Silvi Riccardo , Bartolini Monica , Raffoni Anna , Visani Franco 
Published: February 2015

Purpose– For over 20 years, management control literature has indicated the importance of supporting the strategy development and implementation process with strategic performance measurement systems (SPMS) and integrating traditional financial indicators with a set of multidimensional forward-looking measures focusing on the long term and linked to cause-effect relationships. Nevertheless, knowledge on the specific SPMS models used in practice and their effectiveness in supporting the managerial decision-making process is still fragmented and ambiguous. The purpose of this paper is to first analyse the SPMS models used in practice, also considering the role of strategy and firm size as drivers of adoption, thereafter analysing the capability of SPMS models to provide managers with measures that are consistent with their strategic information needs.Design/methodology/approach– The research is based on a survey involving 88 Italian medium-large sized firms (or subsidiaries of multinational firms) operating on a global level.Findings– The cluster analysis identifies two very different SPMS models used in practice. The first is the Short-term Financial Model, and as its name indicates, is based on short-term, internally focused and unconnected financial indicators. The second is the Multidimensional Additive Model, which integrates financial and non-financial measures but without a fully developed fit with the strategy. The research primarily indicates unsatisfied information needs in both clusters, presenting a significant challenge to the further development of existing SPMS models and in defining new theoretical SPMS frameworks.Practical implications– The adoption of an incremental approach to SPMS, simply adding new operational and strategic non-financial measures without a real fit with the strategy does not increase the information effectiveness of the system.Originality/value– The paper analyses the characteristics and use of SPMS models in practice from an exploratory perspective, defining and applying a model to evaluate the information effectiveness of SPMS.

Authors: Dutra Ademar , Ripoll-Feliu Vicente Mateo , Fillol Arturo Giner , Ensslin Sandra Rolim , Ensslin Leonardo 
Published: February 2015

Purpose
– The purpose of this paper is to know what scientific literature presents about the theme evaluation of seaport performance, thus enabling the construction of knowledge in the researchers and the identification of gaps in the research that will lead to advances in the area from the identification of the characteristics of a portfolio of relevant international publications.

Design/methodology/approach
– From the basic philosophical (constructivism), of the kind strategy (research-action) and the method used for the accomplishment of such strategy (structured process knowledge development process – constructivist (ProKnow-C)) the current research has a qualitative approach.

Findings
– From the analysis of the bibliographic portfolio composed of 23 articles, the main results were: focus of the evaluation of seaport performance is on operational and tactical efficiency rather than on strategic and global performance; the majority of the studies does not relate to the reality experienced by seaport managers due to the limited interaction with these managers, evidencing a distance of the researchers from the object of their research; and performance evaluation was barely used/explored as a tool to support management, only for the sake of evaluation itself.

Research limitations/implications
– The search occurred in the databases Web of Science, Scopus, Proquest, Ebsco, Sciece Direct and Wiley.

Originality/value
– The identification of gaps that might promote advances in this field of knowledge, once the seaport segment is not exploring the potential that performance evaluation can offer and is already available in literature.
Risk indicators for managing the energy procurement process
Authors: Verbano Chiara , Crema Maria 
Published: February 2015

Purpose
– Energy commodities are characterised by rigid demand and high price volatility, linked to many variables such as climate factors, exchange rates, availability of resources. At the same time, the authorities often set prices, so wholesale energy companies need to create margins carefully by managing the procurement process and selecting appropriate tools to manage the risks associated with the volatility of energy prices. The purpose of this paper is to analyse and evaluate price and volume risks in the energy procurement process considering a “non-speculative” point of view, which is understudied in the literature review.

Design/methodology/approach
– The paper adopts a quantitative approach to risk evaluation, based on accounting indicators, and applies it to a large Italian energy wholesale company.

Findings
– A set of key risk indicators to measure price and volume risks is presented in the results, split into synthesis risk, unbalanced risks, modulation risks and risks derived from bilateral contracts. These indicators are applied to the case study, and each risk is prioritised and discussed.

Originality/value
– This contribution is one of the first attempts to analyse energy procurement risks in a non-speculative approach. The proposed method allows: first, to evaluate and prioritise the three major types in the energy procurement process, second, to observe the trend of risk exposure, third, the performance measurement of the procurement process, and fourth, benchmarking activities if widely implemented in the energy sector.

Conceptualizing open agile software development life cycle (OASDLC) model
Authors: Misra Subhas C. , Singh Virender 
Published: February 2015

Purpose
– Software development life cycle (SDLC) has always been the core methodology for any software engineer that depicts the entire development process which an organization is bound to utilize to achieve successful software. The purpose of this paper is to bring forth a conceptual model after analysing the best practices in SDLC, and extracting the best out of agile methodologies and the open source software, thereby bringing forward an optimised structure.

Design/methodology/approach
– The OASDLC is hypothesized specifically for “Brihaspati” project and is formulated keeping in mind the gaps and limitations posed by existing SDLC models. OASDLC is further put to test for achieving lower costs and efforts involved. The tests are further substantiated by means of hypothesis validation through execution of a survey based research.

Findings
– It has been observed that the present conceptual model further optimizes the efforts involved while adopting such a practice.

Originality/value
– This paper proposes a novel SDLC model so as to achieve a best practice for a software project. On analysing the issues involved such as tight budget and timelines, it led the authors to formulate a newer concept “Open Agile Software Development Life Cycle model” (OASDLC).
Patterns of variation and correlation in quality control characteristics of segment installation
Authors: Hosseininasab S. Mohammad E. , Ershadi Mohammad Javad 
Published: February 2015

Purpose
– Evaluation of the quality and performance of a tunnel lining during the installation of segments are the main objects of tunneling projects. Because the quality is affected by several attributes, the purpose of this paper is an appropriate multivariate data analysis that is helpful in extracting applicable knowledge of the data collected regarding the related attributes of the initial installed rings.

Design/methodology/approach
– Principal component analysis (PCA) is used to analyze the data obtained by the quality control team. The authors use canonical correlation analysis (CCA) to extract some linear combinations of the original attributes of the two groups that produce the largest correlations with the second set of variables.

Findings
– The authors reduce the dimensionality of the original data set for further analyses, and use a small number of uncorrelated variables rather than a larger set of correlated variables to take effective and efficient action to control the quality of the tunnel lining. The authors also explore the correlation structure and relationship between two main groups of characteristics used for assessing the quality of the installed rings. Then, instead of a large number of the original characteristics in the two groups, the authors can easily control these few to attain a reasonable quality for the tunnel lining.

Originality/value
– This is a case study, and for each ring selected for inspection, 16 different characteristics are measured and the observations are recorded. The authors use PCA and CCA to analyse the data and interpret the results. Although the methods are not new, applying them to this data results in useful and informative outcomes and interpretation.

Authors: Thakur Rakhi , Srivastava Mala 
Published: February 2015

Purpose
– The purpose of this paper is to develop and empirically test a conceptual model to establish how consumer innovativeness can be used as a variable to positively influence online retailing adoption intention both directly and reducing consumer perceived risk (PR).

Design/methodology/approach
– The literature concerning personal innovativeness toward information technology and major components of PR have been systematically reviewed to develop a conceptual model. The impact of innovativeness and PR on online shopping adoption intention has been empirically validated by structural equation modeling using a sample of 433 internet users in India.

Findings
– Results reveals consumer innovativeness as a key construct to improve online retail adoption intention both directly and by its effective role in reducing consumer risk perception of using internet channel for making purchase of physical goods.

Originality/value
– There is a lack of studies which connect consumer innovativeness and PR in the online retailing context especially in Indian scenario. The results expand one’s knowledge on this relationship, propounding interesting empirical evidence of the model among current and potential online shoppers.
Testing the decoy effect in the presence of store brands
Authors: Sellers-Rubio Ricardo , Nicolau-Gonzalbez Juan-Luis 
Published: February 2015

Purpose
– The purpose of this paper is to test decoy effect in the framework of sales promotion, by conducting several experiments to figure out how this decoy effect is influenced by the presence or absence of a store brand.

Design/methodology/approach
– Several experiments have been conducted to test the validity of the decoy effect and rule out some explanations for the changes in demand that take place. The experiments consider three brands (two national brands and one store brand). All the brand names and prices employed in the experiment are real.

Findings
– The results indicate that, as expected, the inclusion of a decoy in the choice set significantly increases the consumer’s relative preference for the promoted product; however, more importantly, the results also show that store brand consumers are more influenced by a decoy than national brand consumers.

Originality/value
– This paper presents the first evidence of the decoy effect in the presence of store brands.
