Effects of Temperature on Age‐0 Atlantic Menhaden Growth in Chesapeake Bay
Authors: Humphrey Jennifer , Wilberg Michael J. , Houde Edward D. , Fabrizio Mary C. 
Published: September 2014

AbstractAtlantic Menhaden Brevoortia tyrannus is an economically and ecologically important forage fish in the western Atlantic Ocean. In the Chesapeake Bay, its recruitment has been low since the late 1980s, prompting questions on how environmental factors may affect its productivity. Growth is an important component of production, but causes of spatial and temporal variability in growth of age‐0 Atlantic Menhaden are not fully understood. Our objective was to quantify the effect of temperature on spatial and temporal variability in growth of age‐0 Atlantic Menhaden in Chesapeake Bay. We analyzed data on mean length and temperature for years 1962–2011 from nine regions of Chesapeake Bay. We developed a linear model that relates mean total length of Atlantic Menhaden to cumulative growing degree‐days (GDDs) in Chesapeake Bay and validated the model using data that were withheld from the initial parameter estimation. The temperature threshold that best described variability in growth was 14°C, a temperature substantially higher than the physiological threshold for growth. The GDD model explained almost 80% of the variability in mean length over time (within and among years) and among regions. In a model validation exercise, it accurately predicted mean length in tributary subregions of the bay not included in the original model fitting. The GDD model requires only temperature data to effectively predict growth, making it simpler to apply than models requiring more complex approaches.Received August 22, 2013; accepted May 30, 2014

Abstract
In routine diagnostics, real-time reverse transcriptase quantitative PCR (RT-qPCR) has become a powerful method for fish health screening. Collection, transportation, and storage conditions of specimens could dramatically affect their integrity and could consequently affect RT-qPCR test results. In this study, to assess the expression profile of elongation factor 1 alpha (ELF-1α) gene, head kidney (HK) tissues from Atlantic Salmon Salmo salar were exposed at room temperature, 4°C, −20°C, and −80°C as well as in 70% ethanol for 6, 12, 24, 48, and 72 h. Data showed a significant increase of RT-qPCR cycle threshold (Ct) values for ELF-1α ranging from 14.7 to 26.5 cycles for tissues exposed to room temperature. In order to mimic the sample transportation conditions, different temperatures of storage were used and tissue quality was evaluated using ELF-1α gene expression. Data showed that Ct values for ELF-1α increased significantly when the tissues were transported on ice for 2 h, stored at −20°C, thawed on ice for 6 h, and stored again at −80°C. The HK tissues collected from Atlantic Salmon challenged with viral hemorrhagic septicemia virus (VHSV) through intraperitoneal injection were exposed at room temperature for 0, 6, 12, 24, 48, 72, and 96 h. Data showed a good correlation of values for ELF-1α and VHSV Ct although the ELF-1α mRNA of the host degraded faster than the RNA of VHSV. Based on these data, HK tissues could be transported on ice or ice packs without the quality of the tissue being affected when stored at −80°C upon arrival at the laboratory. In addition, 70% ethanol could be used as a preservative for long-distance transportation. For an efficient diagnostic test, a duplex VHSV–ELF-1α was developed and optimized. Data showed that the sensitivity of the duplex assay for VHSV was similar to the singleplex.

Histopathologic Changes in Disease-Resistant-Line and Disease-Susceptible-Line Juvenile Rainbow Trout Experimentally Infected with Flavobacterium psychrophilum
Authors: Marancik David P. , Leeds Timothy D. , Wiens Gregory D. 
Published: September 2014

Abstract
A challenge to selectively breeding fish populations for improved disease resistance in aquaculture is an incomplete understanding of how artificial selection affects innate immunity at the host–pathogen level. The objective of this study was to determine whether Rainbow Trout Oncorhynchus mykiss bred for differential susceptibility to bacterial cold-water disease exhibited altered tissue damage and cellular inflammatory response following experimental challenge with Flavobacterium psychrophilum. Fish from disease-resistant (ARS-Fp-R) and disease-susceptible (ARS-Fp-S) lines were experimentally challenged as juveniles, and mortalities, as well as survivors, were sampled for histopathology during the acute phase of the disease. Microscopic lesions were quantified or semiquantified and statistically compared for changes over time and between genetic lines. Significant progression in the degree of perisplenitis, splenic necrosis, splenic inflammatory infiltrates, average splenic ellipsoid area, total splenic ellipsoid area, and peritonitis was present over time in both genetic lines on at least one postinfection time point. No differences were found between renal inflammatory infiltrates and renal hematopoietic cell depletion over time. Perisplenitis was significantly lower in fish from the ARS-Fp-R line on day 9 postinfection than in fish from the ARS-Fp-S line. The ARS-Fp-R line demonstrated a trend towards reduced splenic necrosis compared with the ARS-Fp-S line that approached significance, and fish from the ARS-Fp-S line were 3.6 times more likely than fish from the ARS-Fp-R line to have a higher splenic necrosis lesion score after day 3 postinfection. These findings support the hypothesis that differential survival is a result of divergence in disease magnitude and not altered disease course between genetic lines. Characterization of histopathologic changes between genetic lines and over time helps elucidate mechanisms of disease resistance and contributes to our understanding of disease pathogenesis in fish infected with F. psychrophilum.

Heart rate variability to assess ventilatory threshold in ski‐mountaineering
Authors: Cassirame Johan , Tordi Nicolas , Fabre Nicolas , Duc Sébastien , Durand Fabienne , Mourot Laurent 
Published: September 2014

AbstractThe capacity to predict the heart rate (HR) and speed at the first (VT1) and second (VT2) ventilatory thresholds was evaluated during an incremental ski‐mountaineering test using heart rate variability (HRV). Nine skiers performed a field test to exhaustion on an alpine skiing track. VT1 and VT2 were individually determined by visual analysis from gas exchanges (VT1V and VT2V) and time‐varying spectral HRV analysis (VT1fH, VT2fH and VT2H). VT1 could not be determined with the HRV methods used. On the contrary, the VT2 was determined in all skiers. No significant difference between HR and speed at VT2H and VT2V was observed (174.3 ± 5.6 vs. 174.3 ± 5.3 bpm, and 6.3 ± 0.9 and 6.3 ± 0.9 km h–1, respectively). Strong correlations were obtained for HR (r = 0.91) and speed (r = 0.92) at VT2H and VT2V with small limits of agreement (±3.6 bpm for HR). Our results indicated that HRV enables determination of HR and speed at VT2 during a specific ski‐mountaineering incremental test. These findings provide practical applications for skiers in order to evaluate and control specific training loads, at least when referring to VT2.
Using the gonadosomatic index to estimate the maturity ogive: application to Chilean hake (Merluccius gayi gayi)
Authors: Flores Andrés , Wiff Rodrigo , Díaz Eduardo 
Published: September 2014

Abstract
The proportion of mature fish at age or length is one of the most important population attributes in assessing reproductive potential. This proportion is usually named the maturity ogive. The most crucial step in estimating this proportion deals with maturity staging assessed by macroscopic or histology analysis. Macroscopic analysis is relatively inexpensive but usually introduces large amount of error. Histology is the most accurate method for maturity staging but is expensive and time consuming. Here, we propose using the gonadosomatic index (GSI) as an alternative way to estimate the maturity ogives. A logistic multinomial model was implemented to separate immature, mature-active, and mature-inactive fish, based only on their value of GSI. We evaluated the performance of the GSI-based method by comparing the results with ogives estimated from macroscopic and histological staging using the extensive database available for Chilean hake (Merluccius gayi gayi). Maturity ogives from GSI analysis were evaluated at the start and end of the reproductive season. Results showed that, in all cases analysed, maturity ogives from GSI were closer to the ogives based on histology than those from macroscopic staging. Comparing across periods, those maturity ogives computed at the start of the reproductive season give estimates very similar to those from histological staging. To have unbiased estimates of maturity ogives from GSI analysis, we recommend using data from the start of the reproductive season to minimise the frequency of spent fish. In addition, the assumption of the isometry between gonad and gutted weight across maturity stages needs to be tested before the use of this GSI method. The analyses presented here provide a promising method to estimate maturity ogives when histological staging data are lacking or when macroscopic analysis is suspected to have large amounts of errors.
Disk dissipation timescale of pre-main sequence stars in Taurus
Authors: Takagi Yuhei , Itoh Yoichi , Oasa Yumiko 
Published: September 2014

Abstract
We present the results of an age determination study of pre-main sequence stars in the Taurus star-forming region. The ages of 10 single stars with masses of 0.5–1.1 M⊙ were derived from the surface gravities, estimated from high-resolution optical and near-infrared spectroscopy. The equivalent width ratios of nearby absorption line pairs were employed for the surface gravity diagnostic, which directly reflects the parameters of the stellar atmosphere without any veiling correction. From a comparison of determined ages and near-infrared color excesses such as J − H, J − K, and J − L, the inner disk lifetime of the young stars with 0.5–1.1 M⊙ in Taurus is estimated to be 3–4 Myr.
Overview of Intraoperative Neurophysiological Monitoring During Spine Surgery
Authors: Shilian Parastou , Zada Gabriel , Kim Aaron C. , Gonzalez Andres A. 
Published: September 2014

Summary:
Intraoperative neurophysiologic monitoring has had major advances in the past few decades. During spine surgery, the use of multimodality monitoring enables us to assess the integrity of the spinal cord, nerve roots, and peripheral nerves. The authors present a practical approach to the current modalities in use during spine surgery, including somatosensory evoked potentials, motor evoked potentials, spinal D-waves, and free-run and triggered electromyography. Understanding the complementary nature of these modalities will help tailor monitoring to a particular procedure to minimize postoperative neurologic deficit during spine surgery.
A tale of oblivion: Ida Noddack and the ‘universal abundance’ of matter
Authors: Santos Gildo Magalhães 
Published: September 2014

Ida Noddack was a German chemist who in 1925, with her husband Walter Noddack, discovered element 75 (rhenium) and possibly element 43 (technetium). She is also known to have anticipated, by nine years, the possibility of nuclear fission. This article focuses on Ida's hypothesis that all elements are present in any mineral. Ida related the relative abundance of the elements in the Universe to hypothetical properties of the atomic nuclei. This allowed her to speculate about a different Periodic Table in which isotopes might be the cause of unexpected features of periodicity. Ida Noddack faced many professional obstacles because of her scientific nonconformity and gender, the resentment of physicists against intrusion in their field, and the overall difficulty of research under and after the Nazi regime.
HIV/AIDS in Lebanese prisons: challenges and proposed actions
Authors: Ammar Diala , Cordova Alberto 
Published: September 2014

Purpose
– The purpose of this paper is to discuss the extent of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) crisis in Lebanese prisons, propose functional reforms for Roumieh prisons (the country's largest male top-security prison), and outline the main challenges to HIV/AIDS prevention, intervention, and treatment.

Design/methodology/approach
– All recommendations were based on previous successful stories, international prison standards as well as cultural considerations.

Findings
– This paper argues that prevention and interventions starts within the prison community including inmates, guards, and other prison and provision of appropriate health care, education, and prison infrastructure.

Social implications
– These strategies are not only important in limiting prevention and transmission of HIV/AIDS, but also contribute in optimizing quality of life within the prison system.

Originality/value
– This paper is the first of its kind to discuss the prison situation in Lebanese prisons in terms of public health promotion and reforms.
“Seek, test, treat and retain” for hepatitis C in the United States criminal justice system
Authors: Larney Sarah , G. Beckwith Curt , D. Zaller Nickolas , T. Montague Brian , Rich Josiah 
Published: September 2014

Purpose
– The purpose of this paper is to consider the potential benefits and challenges of applying a strategy of “seek, test, treat and retain” (STTR) to hepatitis C virus (HCV) in the US criminal justice system.

Design/methodology/approach
– The authors draw on the published literature to illustrate how each component of STTR could be applied to HCV in the US criminal justice system, and describe challenges to the implementation of this strategy.

Findings
– The burden of morbidity and mortality associated with chronic HCV infection in the USA is increasing and without significantly increased treatment uptake, will likely continue to do so for several decades. The authors argue that the US criminal justice system is an ideal focus for HCV case finding and treatment due to a high prevalence of infection and large volume of individuals in contact with this system. STTR would identify large numbers of HCV infections, leading to opportunities for secondary prevention and primary care. Important challenges to the implementation of STTR include treatment costs and training of prison medical providers.

Originality/value
– This paper highlights opportunities to address HCV in the US criminal justice system.
Managing information for collaborative networks
Authors: Durugbo Christopher 
Published: September 2014

Purpose
– The purpose of this paper is to explore the orientations of collaborative networks (CNs) for managing integrated information flow. It seeks to analyse and shed light into the main priorities of firms for sharing and coordinating information with CN partners. These priorities are needed to enhance practices to trade-off and integrate flows where appropriate for maximising profits and performance.

Design/methodology/approach
– In this study, inductive multiple-case logic is applied to research how six industrial firms manage integrated information flow in relation to their collaborative networked organisations (CNOs). Guided by an interpretivism epistemology, 22 face-to-face and 13 telephonic semi-structured interviews were conducted with 14 key informants in six industrial firms. Interview data were analysed in line with the research agenda to understand orientations for integrated information flow.

Findings
– The research finds that CN management is enhanced when flow integration for industrial firms is skill, project, agreement and relationship oriented. The investigation also finds that CNO flow integration could be enhanced when industrial firms confront and prioritise schemes for fluidity prevention, systematised templates, procedural prompts, implementation checklists, confidence building, issuance policies and concern separation.

Originality/value
– The major contribution of this paper is an exposition on priorities for integrated information flow within CNs. It also offers insights that suggest industrial firms can boost the performance of their CNOs by: working in small knit highly skilled teams, tactically implementing manufacturability and marketability programmes, strategising their production contracts and strengthening their company-customer-supplier ties.
Innovation with IS usage: individual absorptive capacity as a mediator
Authors: Wang Weiwei , Liu Luning , Feng Yuqiang , Wang Tienan 
Published: September 2014

Purpose– After information systems (IS) implementation, many organizations report that system underutilization causes the failure to meet expected IS investment returns. It is imperative to understand the way to leverage employees’ fullest potential in the IS usage. The paper aims to discuss these issues.Design/methodology/approach– Anchoring on absorptive capacity (ACAP) theory, the authors develop an employee innovation model. Using survey data and structural equation modeling, this research investigates how perceived organizational levers affect innovation with IS usage (INVU) by introducing individual ACAP as a mediator.Findings– The authors find general support for the research model through a survey of 205 employees using SAP business intelligence systems in China. The empirical data shows that three interrelated components of individual ACAP significantly contribute to INVU. The findings also suggest that, both fairness of reward and job autonomy are key organizational levers for the utility of individual ACAP. Furthermore, their effects on INVU can be fully mediated by individual ACAP.Originality/value– The authors empirically unpack and validate individual ACAP in IS innovation situation. The findings provide academics and practitioners with an understanding of how management can inspire employees’ potential in implemented system innovation.
Integration and consistency between web and mobile services
Authors: Yang Shuiqing , Wang Yan , Wei June 
Published: September 2014

Purpose
– Attracted by tremendous market opportunities of mobile business, many web services providers have started to expand their web services from traditional PC-based environment into the mobile-based environment. However, success in the web services cannot guarantee the success in the mobile services. The purpose of this paper is to identify factors that influence consumer evaluation and use of mobile shopping services in a web-mobile service extension context.

Design/methodology/approach
– Based on categorization theory, this paper focusses on the role of integration and consistency between web and mobile services. A research model was created and empirically tested on data collected from 298 mobile shopping users in China.

Findings
– The structural equation modeling analysis indicates that evaluation of source (web service quality) positively affect evaluation of target (perceived mobile service quality and flow in mobile services). The study also found that the relationships between source and target (perceived integration and perceived consistency) play an important role in determining evaluation of the target, which in turn shapes intention to use mobile services.

Research limitations/implications
– The survey is based on mobile shopping consumers. Caution is required in any effort to generalize the findings to other research contexts. Factors influencing a consumer's extension or adoption decisions in regard to different mobile services may not be the same, or the degree of influence may differ. Continued studies can test and compare our findings in different mobile services contexts.

Practical implications
– The results of the findings provide specific methods for managing the process of web-mobile service extension. The results also indicate the importance of perceived consistency in shaping consumers’ evaluation of the extended mobile services in practical environments.

Originality/value
– The present study extends the categorization theory to a multi-channel context and examines mobile services adoption from a cross-environment perspective. It considers evaluation of source, evaluation of target, and the relationships between source and target, which enriches the innovation adoption literature by providing a holistic insight into the evaluation and use of mobile services.
