Published: July 2012

SUMMARYViral hepatitis is recognized as one of the most frequently reported diseases, and especially in China, acute and chronic liver disease due to viral hepatitis has been a major public health problem. The present study aimed to analyse and predict surveillance data of infections of hepatitis A, B, C and E in Wuhan, China, by the method of time-series analysis (MemCalc, Suwa-Trast, Japan). On the basis of spectral analysis, fundamental modes explaining the underlying variation of the data for the years 2004–2008 were assigned. The model was calculated using the fundamental modes and the underlying variation of the data reproduced well. An extension of the model to the year 2009 could predict the data quantitatively. Our study suggests that the present method will allow us to model the temporal pattern of epidemics of viral hepatitis much more effectively than using the artificial neural network, which has been used previously.

Published: July 2012

AbstractObjectivesTo describe our experience in the management of coronary artery anomalies both in an adult and in a paediatric population and to compare the two groups for finding out differences in terms of angiographic incidence and treatment.Patients and methodsDatabases at the Department of Cardiology of San Martino Adult's Hospital and of Gaslini Children's Hospital were searched for all patients with a diagnosis of coronary artery anomaly who underwent coronary angiography between 1994 and 2006.ResultsCoronary anomalies were diagnosed in 76 (1%) adult patients. Anomalous left circumflex artery was the commonest coronary anomaly (25%). Anomalous left coronary artery from pulmonary artery and myocardial bridges were the only anomalies responsible for angina-like symptoms. No patients except the one with anomalous left coronary artery from pulmonary artery needed surgical intervention. In the paediatric population, we found 28 (0.9%) patients with coronary anomalies. Anomalous left coronary artery from pulmonary artery was the most common anomaly (48%) and always required emergency surgical treatment; in addition there were two patients with stenosis of the left main coronary artery.ConclusionCoronary artery anomalies may be associated with very acute, even life-threatening symptoms in children, whereas they are usually clinically silent and detected by accident on coronary angiography in adults. Recognition of coronary artery anomalies enables early treatment or close follow-up in children, whereas it could be useful in case of cardiac surgery in adults.
Direct observation of kinetic traps associated with structural transformations leading to multiple pathways of S-layer assembly

Published: July 2012

The concept of a folding funnel with kinetic traps describes folding of individual proteins. Using in situ Atomic Force Microscopy to investigate S-layer assembly on mica, we show this concept is equally valid during self-assembly of proteins into extended matrices. We find the S-layer-on-mica system possesses a kinetic trap associated with conformational differences between a long-lived transient state and the final stable state. Both ordered tetrameric states emerge from clusters of the monomer phase, however, they then track along two different pathways. One leads directly to the final low-energy state and the other to the kinetic trap. Over time, the trapped state transforms into the stable state. By analyzing the time and temperature dependencies of formation and transformation we find that the energy barriers to formation of the two states differ by only 0.7 kT, but once the high-energy state forms, the barrier to transformation to the low-energy state is 25 kT. Thus the transient state exhibits the characteristics of a kinetic trap in a folding funnel.
Quantifying Latent Impacts of an Introduced Piscivore: Pulsed Predatory Inertia of Lake Trout and Decline of Kokanee
Authors: Schoen Erik R. , Beauchamp David A. , Overman Nathanael C. 
Published: July 2012

AbstractIntroduced long‐lived predators often cause significant impacts on their prey, but these impacts can be masked from detection due to high “predatory inertia”: time lags in population growth and dietary ontogeny. We evaluated whether predation by introduced lake trout Salvelinus namaycush could explain the 88% decline in escapement of kokanee Oncorhynchus nerka during 2005–2009 in Lake Chelan, Washington. We quantified the strength and trend of predation impacts with field sampling, a hydroacoustic assessment of kokanee production, and bioenergetics and age‐structured population models of lake trout. Lake trout consumption of kokanee exceeded kokanee production, indicating strong predation impacts at the start of the decline. Fully piscivorous lake trout (>550 mm fork length) were responsible for 83% of this predation. The population model predicted that a pulse of strong stocked cohorts crossed this piscivorous size threshold, causing the biomass of fully piscivorous lake trout to expand by roughly 70–300% during 2004–2009 and driving predation pressure to peak levels. Together, these results suggested that lake trout predation was a large and growing source of kokanee mortality during the decline. Counterintuitively, predation pressure was projected to increase even if the numbers of harvestable lake trout declined, as strong cohorts grew to piscivorous size while succumbing to mortality. Angler catch rates of lake trout declined by 40% during 2004–2007, as was predicted by the population model; this decline in catch masked the rise in predation pressure. This analysis demonstrates the potential for introduced predators exhibiting high predatory inertia to cause strong, latent impacts on prey that would be unexpected based on harvest trends and prior dynamics alone. Forward‐looking monitoring and modeling analyses are clearly advantageous for managers who seek to maintain ecosystems in long‐term “balance” by detecting and reversing incipient changes in predation.
Visible Implant Elastomer (VIE) Tags for Marking Small Rainbow Trout
Authors: Leblanc C. A. , Noakes D. L. 
Published: July 2012

Abstract
Being able to individually follow fish &lt;40 mm in length is a challenge for fish research. In the present study we examined whether the use of visible implant elastomer (VIE) tags is suitable for research on first-feeding rainbow trout Oncorhynchus mykiss raised under laboratory conditions. We assessed the effect of tagging and tagging location on the growth and survival of juveniles over a 34-d period. We also documented the retention rate and visibility of the tags under natural light. This study validates the use of VIE tags for 25–40-mm fish under laboratory conditions, using the base of the dorsal fin and upper or lower caudal fin as tagging locations.

A new approach to detect coherent modes using microwave reflectometry
Authors: Estrada T. , Happel T. , Blanco E. 
Published: July 2012

Abstract
A new approach to detect coherent modes using microwave reflectometry is presented. The proposed approach is based on the modulation of the reflecting layer in the poloidal direction due to the presence of rotating coherent MHD modes. The applicability of the approach is demonstrated, using either conventional or Doppler reflectometry, in plasmas with a high background turbulence level where the standard analysis method fails.

Abstract
Summary: We developed MolBioLib to address the need for adaptable next-generation sequencing analysis tools. The result is a compact, portable and extensively tested C++11 software framework and set of applications tailored to the demands of next-generation sequencing data and applicable to many other applications. MolBioLib is designed to work with common file formats and data types used both in genomic analysis and general data analysis. A central relational-database-like Table class is a flexible and powerful object to intuitively represent and work with a wide variety of tabular datasets, ranging from alignment data to annotations. MolBioLib has been used to identify causative single-nucleotide polymorphisms in whole genome sequencing, detect balanced chromosomal rearrangements and compute enrichment of messenger RNAs (mRNAs) on microtubules, typically requiring applications of under 200 lines of code. MolBioLib includes programs to perform a wide variety of analysis tasks, such as computing read coverage, annotating genomic intervals and novel peak calling with a wavelet algorithm. Although MolBioLib was designed primarily for bioinformatics purposes, much of its functionality is applicable to a wide range of problems. Complete documentation and an extensive automated test suite are provided.

Authors: Ahrendsen Bruce L. , Katchova Ani L. 
Published: July 2012

PurposeThe purpose of this research is to evaluate the financial performance measures calculated and reported by the Economic Resource Service (ERS) from Agricultural Resource Management Survey (ARMS) data. The evaluation includes the calculation method and the underlying assumptions used in obtaining the reported values. Recommendations for improving the information reported are proposed to ERS.Design/methodology/approachThe financial measures calculated and reported are compared with those recommended by the Farm Financial Standards Council (FFSC). The underlying assumptions are identified by analyzing the software code used in calculating the values reported. The values reported by ERS are duplicated and alternative methods for calculating the financial performance measures are considered. The values obtained from the various calculation methods are compared and contrasted.FindingsRecommendations for ERS include: calculate and report the financial measures recommended by FFSC, note values that are imputed, periodically update and validate assumptions used in calculating imputed values, review its policy for flagging estimates as statistically unreliable, report medians and other select percentiles, and consider reporting the percent of farm businesses that have values within critical zones.Originality/valueA total of four methods for calculating financial performance measures are compared and contrasted. These are the aggregate mean, sample mean, sample median, and percentage of farm businesses with values in critical zones.
What drives Greek consumer preferences for cask wine?
Authors: Chrysochou Polymeros , Corsi Armando Maria , Krystallis Athanasios 
Published: July 2012

PurposeCask wine (bag‐in‐box, soft pack) has not received considerable attention in wine marketing research, but interest among winemakers and consumers has been increasing steadily. However, little is known about what drives consumer preferences for cask wine and, furthermore, what the profile of the cask wine consumer is. This study aims at filling this gap.Design/methodology/approachBased on a web‐based survey, the best‐worst scaling (BWS) method was applied to measure the importance of attributes that Greek consumers assign when choosing cask wine. Then, a latent class clustering analysis based on the importance ratings of the attributes was applied in order to segment the Greek cask wine market.FindingsThe most important attributes were found to be price, quality and convenience packaging, whereas brand, grape variety and origin were found to be the least important ones. In relation to structure, the Greek cask wine market was found to consist of four distinct segments that were labelled as connoisseurs, convenience seekers, experienced and risk averse. These segments showed differences in relation to their past experience and in the importance given to intrinsic (quality, taste, origin) as opposed to extrinsic cues (brand, price, convenience packaging).Research limitations/implicationsTwo main strategic directions are suggested to Greek cask wine producers: they can either maintain the current approach to the market by providing a “simple”, not particularly refined wine, or adopt a sustainable eco‐friendly positioning.Originality/valueThis study contributes to the understanding of what drives consumers' preferences for cask wine, something that few studies have done until now. Moreover, this is the first study to use the BWS method for this type of product.
Brokering knowledge from universities to the marketplace
Authors: Berbegal‐Mirabent Jasmina , Sabaté Ferran , Cañabate Antonio 
Published: July 2012

PurposeThis study aims to conceptualise the role of knowledge transfer offices (KTOs) as knowledge brokers (KBs) and identify which factors are most significantly related with their performance for supporting public‐private research organizations (PROs), testing the authors' hypothesis for the Spanish case.Design/methodology/approachAn empirical analysis is conducted based on data from RedOTRI 2008 annual report about 63 Spanish KTOs. A multiple lineal regression model is carried on each of the selected variables representative of KTOs' performance (number of priority patents, revenues from industry collaboration and number of spin‐offs) in order to establish possible relationships with some factors related to the knowledge process that characterize KTOs' activity.FindingsA theoretical framework conceptualizing the KTOs' role as knowledge brokers is suggested. Factors positively influencing KTOs' performance are PRO's total annual expenses, the type of PRO, the KTO age, the existence of a science park, the explicit regulation of intellectual property rights, the number of specialized full‐time staff of the KTO and the availability of a patent stock.Practical implicationsThe practical implication is the identification of those critical factors for the day‐to‐day operation of Spanish KTOs in their different ways of transferring knowledge, drawing managerial and organisational practices that may improve their performance.Originality/valueThis paper provides two original contributions for literature on knowledge transfer: a theoretical framework for the conceptualisation of KTOs as KBs, and the categorisation and further analysis of factors closely related to the performance of KTOs. A set of managerial implications for a better improvement of such institutions is presented.
A simulation model with synchronization manufacturing stations
Authors: Lin Feng‐Jyh , Chen Yi‐Min 
Published: July 2012

PurposeThe aim of this paper is to develop an efficient analytical procedure to evaluate performance of the most general pull production systems particularly when multiple‐part‐types are involved. The authors consider a kanban controlled production system that can be modelled as a closed queuing network with different product classes. The production line is decomposed into stages which consist of one or several stations and an output buffer. Each stage is associated with a given number of kanbans. The main idea of this analytical algorithm is to analyze each subnetwork individually using a product form approximation technique. The iterative procedure is used to find the unknown parameters.Design/methodology/approachThe authors design a multiclass queuing network that can be used to represent kanban controlled production systems. To solve this model, three procedures are used: decompose the original network into M subnetworks, convergence of unknown parameters in each subnetwork, and convergence of unknown parameters in the original network. The authors now describe these procedures separately.FindingsThe main contribution of this paper is the formulation of the problem of kanban controlled production systems with several part‐types. The methodology is based on approximate formula with decomposition and is applicable to more general manufacturing environments. The authors' method can be applied to both limited and unlimited demands. The analytical algorithm designed in this work has demonstrated excellent performance in analyzing kanban controlled production systems.Originality/valueThe methodology of this algorithm is based on approximate formula and is applicable to more general manufacturing environments.

Various legal concerns and theories were developed from this information.FindingsThe various legal theories were organized into a three‐category framework: Monitoring; 'Mposters; and Message.Practical implicationsThis framework should be useful to brand managers to protect their brand against unauthorized use, imitation or unfavourable affiliations in social media.Originality/valueThis work is the first to develop a managerial framework of legal issues to address unauthorized and unfavourable use of a brand identity in social media.
Socio‐ecological consequences of charitable food assistance in the affluent society: the GermanTafel
Authors: Lorenz Stephan 
Published: July 2012

PurposeCharitable food assistance in affluent societies shows a polarisation between growing abundance, on the one hand, and social exclusion, on the other. It establishes a connection between both sides. In Germany, such charity is especially represented by the so‐calledTafelnon‐profit organisation. The purpose of this article will be to explore the structural problems of the non‐profit organisations' charitable practices.Design/methodology/approachThis qualitative study encompassedTafelinitiatives, the donating businesses and the people on the receiving end.FindingsIt will be shown that collecting and distributing excess food is at least an ambivalent, to some degree even conflictive means and that it is hardly the solution to the social and ecological problems addressed. Charitable food assistance contributes more to cementing exclusion and excess rather than to overcoming them.Originality/valueThe article will draw conclusions on unrealistic views of exclusion and problematic operations of the movement itself.
Rethinking the role of church in a socio‐democratic welfare state
Authors: Hiilamo Heikki 
Published: July 2012

PurposeThe purpose of this paper is to focus on the role of church in relation to state in providing support for needy.Design/methodology/approachThe analysis takes place in a Nordic welfare state context between two recessions in the early 1990s and late 2000s. The welfare state regime hypothesis suggests that the kind of traditional assistance the church lends to the poor would die out in the course of “socio‐democratic” welfare state development, a statement analogous with the secularization hypothesis.FindingsWith data on the volume of poverty alleviation activities of the Finnish Evangelical Lutheran Church it is shown that after decades of marginalization, the role of the church's poverty alleviation became more pronounced after the recession in the early 1990s and continued to do so throughout the economic collapse of 2008.Research limitations/implicationsThe results give ground to challenge the conventional clear cut conception of the universal Nordic welfare state model.Originality/valueEuropean welfare state research has focused on the links between religious values, religious cleavages and the shaping of the welfare state but has mostly ignored the role of faith‐based institutions in improving welfare. The current economic crisis may provide religious institutions a window of opportunity to expand their poverty alleviation activities.
Temporal causality and the dynamics of crime in Turkey
Authors: Halicioglu Ferda 
Published: July 2012

PurposeThe purpose of this paper is to study empirically the dynamics of crime in Turkey at aggregate and disaggregate levels and provide empirical evidence of temporal causality between crime, health, income, divorce, urbanization and security expenditures.Design/methodology/approachThe paper employs bounds testing cointegration procedure, augmented causality tests and variance decompositions.FindingsThe empirical results suggest the existence of cointegration amongst the variables. Augmented Granger causality tests and variance decomposition analyses indicate the different level, long‐term associations between the variables.Practical implicationsConclusions drawn from this study could be useful for the policy makers and practitioners in international law organizations.Originality/valueThe paper provides first‐time, comprehensive, time‐series evidence on the dynamics of crime in Turkey using the framework of cointegration and causality tests.
Property evaluation of 304L stainless steel fabricated by selective laser melting
Authors: Abd‐Elghany K. , Bourell D.L. 
Published: July 2012

PurposeAdditive manufacturing raw material cost has been recently confirmed as a significant obstacle to widespread deployment of these technologies in industry. Aiming at reducing the cost of the selective laser melting (SLM) process, the purpose of this paper is to evaluate the different properties of products fabricated by SLM using low‐cost ($10/Kg) feedstock 304L stainless steel powders. The entire process cost was also evaluated.Design/methodology/approachUsing an experimental approach, 24 samples with different shapes and sizes were fabricated with layer thickness of 30, 50 and 70 μm and laser scanning speed set at 70 and 90 mm/s. Part geometry, dimensional tolerance, surface quality, density, mechanical properties and microstructure were evaluated.FindingsResults confirmed that the SLM of low‐cost 304L powder was successful and could produce functional parts with fine details and small wall thickness. Using small layer thickness and low scanning speed improved the properties by more than 20 per cent. At a layer thickness of 30 μm and speed of 70 mm/s, density was 92 per cent and hardness was 190 HV. At layer thickness of 70 μm porosity increases and cracks started to form which decreased strength and ductility. The steel remained austenitic with no carbide films at grain boundaries due to the high melting and cooling cycles.Research limitations/implicationsThis research was limited to 304L powders. Future work should be done on different materials and should include the effect of post processing heat treatment on improving the mechanical properties and microstructure.Practical implicationsThe cost of the SLM process using feedstock powders was less than 10per cent of the cost of using the special powders from a machine manufacturer with almost no effect on product quality.Originality/valueThe paper describes how cost reduction in the SLM process was achieved by using 304L powder.
