The impact of the new wine common market organization (CMO) on behavioural loyalty towards product attributes: A case from Italy
Authors: Corsi Armando Maria , Overton Sarah Rann , Casini Leonardo 
Published: April 2014

ABSTRACTThis paper explores the changes in consumers' loyalty towards wine after the launch of the new common market organization (CMO) (European Council Regulation (EC) No. 479/2008) in 2008. The analysis of wine purchases in the AC Nielsen Consumer Panel in 2009 and 2010 was compared to analogous work conducted in 2003–2005 and 2006–2008. Loyalty towards wine attributes— price, quality designation and packaging format—was measured using standard brand performance measures together with a newer metric, the polarization index, which has not been used before to highlight or explain the factors behind shifts in loyalty. The analysis revealed that post‐CMO reform increases in consumer loyalty towards the following: (i) standard 0.75‐L wine bottles; (ii) quality‐classified, protected designation of origin wines; and (iii) higher‐price‐point wines. The paper elaborates these findings, explaining how changes in consumers' loyalty patterns can be used to quantify the success of recent policy changes, which can be tracked in a reasonably short time frame thanks to the polarization index.

The real difference between consumers' perceptions of private labels and national brands
Authors: Nenycz‐Thiel Magda , Romaniuk Jenni 
Published: April 2014

ABSTRACTThis paper documents the application of prior knowledge about response patterns in brand image data for private label (PL) brands. We investigate if a well‐known pattern about response level and usage experience also holds for PLs. The main finding is that advertised national brands (NBs) enjoy a higher level of knowledge amongst their non‐users than do PLs. We did not find this to be the case for small non‐advertised NBs and small PLs. The finding emphasises the importance of advertising for NBs to maintain their position. Well‐branded and appropriately scheduled advertising leads to building up brand associations in consumers' memory, which increases the probability of thinking about or noticing a brand. We suggest that the higher knowledge among NB non‐users is the main advantage NBs have over PLs in the market. We provide implications of the findings for managers and academia.

Neural correlates of sensory‐enabling presentation: An fMRI study of image zooming and rotation video effects on online apparel shopping
Authors: Jai Tun‐Min (Catherine) , O'Boyle Michael W. , Fang Dan 
Published: April 2014

ABSTRACTFor experience products, such as apparel, sensory‐enabling presentations that provide a sense of tactile experience have been suggested as an effective strategy to reduce perceived risk and increase the likelihood of a pleasurable shopping experience. Using functional Magnetic Resonance Imaging (fMRI), we investigated whether sensory‐enabling presentations, specifically, image zooming and rotation videos, would evoke different cognitive and affective brain functions during product evaluation and purchase decision processes. The results suggested that whereas image zooming may evoke more visual perception in the product evaluation process, the rotation view evokes more mental imagery, pleasure, and reward anticipation during the purchase decision process.

Authors: Ma Manling , Xue Feixue , Yang Chao , Xia Wujiong 
Published: April 2014

AbstractThe photochemical behavior of bicyclo[2.1.1]hexyl derivatives was investigated by irradiation with a 450 W medium‐pressure mercury lamp in acetonitrile solution. The irradiation of methyl bicyclo[2.1.1]hexane‐5‐carbonylbenzoate (1a) led to both Norrish type II cyclization and cleavage products with a molar ratio of 1:2.2, whereas the irradiation of methyl 5‐methylbicyclo[2.1.1]hexane‐5‐carbonylbenzoate (1b) afforded the only Norrish/Yang photocyclization compound as the sole product. Such results were illustrated by several geometric parameters for Norrish/Yang photoreaction as ϕ1, ϕ4 and β obtained from the crystal structures. Furthermore, asymmetric photochemical studies using ionic chiral auxiliary technique were also conducted in the solid state.

Financial Factors Influencing the Quality of Corporate Social Responsibility and Environmental Management Disclosure: A Quantile Regression Approach
Authors: Ortas Eduardo , Gallego‐Alvarez Isabel , Álvarez Etxeberria Igor 
Published: April 2014

AbstractThis paper revisits the influence of companies’ financial factors on the extent of corporate environmental sustainability reporting (CESR) in an impressive sample of 3931 companies operating in 51 industries and 59 countries. A CESR composite index is constructed for each company that focuses on the G3 core environmental indicators from the Global Reporting Initiative because they are material for most organizations. In a methodological innovation, this study employs a quantile regression that unfolds certain interesting effects of financial drivers on the intensity of CESR that have not previously been revealed. Considering a combination of the main underlying theories of corporate sustainability reporting – legitimacy theory, agency theory, political costs theory, and signal theory – offers a better understanding of the complex structure of the dependencies found among factors such as company size, leverage, return on assets, research and development spending, market return and market capitalization, and commitment to environmental reporting.

Flow cytometry as a rapid and reliable method to quantify sperm viability in the honeybee Apis mellifera
Authors: Paynter Ellen , Baer‐Imhoof Barbara , Linden Matthew , Lee‐Pullen Tracey , Heel Kathy , Rigby Paul , Baer Boris 
Published: April 2014

AbstractAn important measure of male quality is sperm viability; i.e., the percentage of live sperm within an ejaculate, as this provides an accurate measure of the number of sperm potentially available for egg fertilization. Sperm viability is often determined by fluorescence microscopy using dyes that differentially stain viable and nonviable sperm, but the technique has a number of limitations. Here, a flow cytometry (FCM) method was developed, which allows the rapid determination of honeybee sperm viability, facilitating high throughput analyses. Using samples with known sperm viabilities, it was found that data obtained from FCM were more accurate and less variable compared with data obtained for the same samples using fluorescence microscopy. It was also found that a previously reported additional population of honeybee sperm found in datasets using FCM is caused by freeze–thawing samples. In conclusion, the method described here allows to quantify sperm viability of honeybees quickly and with high accuracy. This will be of great value for future scientific research and could also be of value to guide future bee breeding programs, given the agricultural importance of honeybees as pollinators. © 2014 International Society for Advancement of Cytometry
Traffic matrix estimation: Advanced‐Tomogravity method based on a precise gravity model
Authors: Zhou Haifeng , Tan Liansheng , Ge Fei , Chan Sammy 
Published: April 2014

SummaryTraffic matrix (TM) is extremely important in many networking operations. This paper proposes a novel approach of TM estimation in large‐scale IP networks, termed as Advanced‐Tomogravity method, which is based on a precise gravity model and the tomography method. First, the precise gravity model is proposed on the basis of the existing generalized gravity model by introducing a relativity factor vector parameter, which defines the relativity between the solution of the existing generalized gravity model and its real TM. The solution obtained from this precise gravity model is then refined by the basic model of the tomography method. By mathematical analysis, we give the explicit expression of the relativity factor vector parameter in the proposed precise gravity model by the Moore–Penrose inverse and the minimum‐norm least‐square solution. The vector parameter is subsequently determined with the aid of small amount of historical real data of TM. A general algorithm of the proposed approach is therefore designed. Finally, our approach is validated by simulation using the real data of the Abilene Network. The simulation results indicate that it reduces the relative errors to less than one‐half, better tracks not only the dynamic fluctuations but also the overall mean behavior of traffic flow.

Published: April 2014

AbstractTragendes Mauerwerk wird nicht nur vertikalen, sondern auch horizontalen Kräften ausgesetzt, z. B. aus Wind‐ und Erdbebenlasten. Der Mörtel muss die (vertikalen und horizontalen) Lasten zwischen den Steinen übertragen. Das Verhalten des Mörtels bis zu den ersten Rissen, aber vor allem auch nach Erreichen der Zugfestigkeit entscheidet über die Tragfähigkeit des gesamten Mauerwerksverbandes. Dazu ist die Kenntnis der bruchmechanischen Eigenschaften des Mörtels notwendig. In dieser Arbeit werden diese Eigenschaften von unterschiedlichen Mörteln mit Hilfe der Keilspaltmethode nach Tschegg untersucht. Es kommen die bei Altbauten oft vorhandenen Kalkmörtel sowie die heutzutage üblichen Kalkzement‐ und Zementmörtel zum Einsatz. Die Kraft‐Rissöffnungs‐Kurven, die Kerbzugfestigkeit sowie die Bruchenergien stellen die ermittelten Werte dar. Diese Ergebnisse sollen besonders im Hinblick auf die Ermittlung der Druck‐ und Schubfestigkeit von Bestandsmauerwerk von Nutzen sein.Uni‐ and biaxial fracture behaviour of mortar in brick masonry. Load‐bearing walls are not only exposed to vertical, but also horizontal loading conditions, e.g. from wind or earthquakes. The mortar has to transmit the (vertical and horizontal) loads between the bricks. The behaviour of the mortar up until the first cracks appear, but also mainly after reaching the tensile strength decides about the load bearing capacity of the whole masonry. Hence, knowledge about the fracture mechanical behaviour of mortar is essential. In this article the fracture mechanical properties of different mortars are analyzed using the wedge splitting test according to Tschegg. Lime mortar as well as nowadays used lime cement mortars and cement mortar are tested. The former is often used in still existing old buildings. Force versus crack opening curves, notch tensile strength and fracture energy are the determined values. These results will be useful with regard to the pressure and shear capacity of existing brick masonry.
Einfluss der Belastungsrichtung auf die einaxiale Druckfestigkeit von Proben aus Vollziegeln

Published: April 2014

AbstractAus der Geologie ist vor allem bei geschieferten Gesteinen ein Einfluss der Belastungsrichtung auf die einaxiale Druckfestigkeit bekannt. Dieser Einfluss lässt sich vor allem aus der Lage der einzelnen Schieferflächen bzw. Klüften zur Richtung der Lasteinleitung ableiten. Diese Eigenschaft kann durch unerwartete geringere Festigkeiten zu Problemen bei der Abschätzung der Tragfähigkeit führen. Im Rahmen dieses Beitrags wird am Beispiel durchgeführter kleinmaßstäblicher Labortests die Fragestellung behandelt, ob sich eine Abhängigkeit von der Belastungsrichtung auch für Vollziegel feststellen lässt. Hierzu wurden Bohrkerne aus zwei Chargen historischer Mauerziegel sowie aus handelsüblichen Normalformat‐Mauerziegeln entnommen. Die Druckfestigkeit wurde mittels einaxialen Druckversuchs nach EN 772‐1 bestimmt. Hierbei zeigt sich, dass insbesondere bei maschinell gefertigten Ziegeln ein Einfluss in Abhängigkeit von der Richtung der Lasteinleitung auftritt. Bei den historischen Ziegeln zeigt sich ein Einfluss nur in sehr geringer Weise, insbesondere weil die deutlich größeren Inhomogenitäten im Werkstoff andere Effekte überlagern. Für die Abschätzung der Tragfähigkeit von bestehenden Bauwerken aus Mauerwerk können die Ergebnisse dieser Arbeit einen wertvollen Beitrag liefern. Gerade bei Bestandsbauwerken ist der Einfluss nicht bekannter Materialparameter eine wichtige Grundlage für die Beurteilung.Influence of loading direction on the uniaxial compressive strength of solid brick. The influence of the loading direction on the uniaxial compressive strength is well known from geology in case of cleavage stones. This relation is caused by both the orientation of the single cleavages, the laminar interlock and the gaps within the stone to the loading direction. These phenomenons can cause problems in evaluating the performance of existing structures due to the fact of unexpected low values for the compressive strength. Within this contribution it is discussed, based on small‐scale laboratory tests if this correlation is also valid for brick stones. For this purpose two charges from historical bricks from the 19th century and from one series of new bricks disked‐shaped specimens were taken. These drill cores were conditioned to equal testing conditions and loaded up to failure according to EN 772‐1. These tests show, that in case of machine‐made bricks there is an influence of the loading direction to the value of the compressive strength. In case of historical bricks the influence of the loading direction does not exceed the uncertainties and inhomogeneity which are given by the raw material and the manufacturing procedure. The results of this contribution can be used for the assessment of existing structures made of masonry. In these cases material parameters often are unknown and have to be determined by experimental testing.
The Cd6 gene as a permissive locus for targeted transgenesis in the mouse
Authors: Ichise Hirotake , Ichise Taeko , Sasanuma Hiroki , Yoshida Nobuaki 
Published: April 2014

SummaryThe introduction of a transgene into the genome through homologous recombination or sequence‐specific enzymatic modification is a key technique for producing transgenic mice. The Rosa26 gene has been widely used to produce transgenic mice because the gene is transcriptionally active in various cell types and, at many developmental stages, is permissive for constitutive expression of integrated transgenes, and is dispensable for normal development. However, permissive loci other than Rosa26 are needed to generate mice that harbor multiple transgenes for complex studies. Here, we identified the Cd6 locus on mouse chromosome 19 as a transgene integration site in a transgenic mouse strain showing widespread reporter expression. Using this locus, we generated a knock‐in mouse line that harbors a CAG promoter‐driven reporter transgene, and found that the homozygous transgenic mice are viable and fertile, although transgene insertion disrupted Cd6 gene expression. The transgene on the Cd6 locus expressed reporter genes extensively throughout embryos, neonates, and adults. Combined with the Cre/loxP binary system, blood and lymphatic endothelial cell‐specific reporter expression from the transgenic locus was achieved. These results suggest that Cd6 is valuable as an alternative site for targeted transgenesis. genesis 52:440–450, 2014. © 2014 Wiley Periodicals, Inc.
Barriers to Resource Efficiency Innovations and Opportunities for Smart Regulations − the Case of Germany
Authors: Jordan Nino David , Lemken Thomas , Liedtke Christa 
Published: April 2014

ABSTRACTThere are a variety of economic and ecological benefits to increased resource efficiency. Social, institutional and technical innovations can all contribute towards efficiency increases. Companies face different hurdles in fostering such innovation. Small and medium‐sized companies are subject to specific constraints that may prevent them from benefiting from innovation‐induced resource efficiency improvements. Qualitative interviews were conducted among German small and medium‐sized enterprises (SMEs) and intermediaries to identify barriers for resource efficiency innovations and to elaborate a policy mix at the federal level that could help SMEs to overcome these. We found five major barriers to resource efficiency innovations in German SMEs, comprising deficits in innovation culture, inter‐firm cooperation along the value chain, finance, awareness and take‐up of government funds. We propose a distinct policy mix as a response to this situation. The policy mix comprises the interlocking and synergistic elements of government funding schemes, innovation agents and innovation laboratories.

Towards a Systematic Framework for the Analysis of Environmental Policy Integration
Authors: Runhaar Hens , Driessen Peter , Uittenbroek Caroline 
Published: April 2014

ABSTRACTEnvironmental policy integration (EPI) refers to the incorporation of environmental concerns in non‐environmental policy sectors. EPI aims to avoid conflicts between environmental and other policy objectives and to enhance environmental policy by directly targeting the driving forces of environmental degradation. In practice, however, the potential of EPI has not been fully utilized. Scientific knowledge of EPI is found in several, largely isolated, bodies of literature (on EPI, climate policy integration and environmental impact assessment/strategic environmental assessment) and does not provide an adequate answer to the question of what EPI strategies work, where and why. A systematic framework based on comparative empirical research is required to contribute to more effective EPI strategies. In this paper we formulate a research agenda for the development of such a framework on the governance of EPI that is robust, i.e. builds on other theories of environmental governance and policy change and that envisages large‐scale, international comparative empirical analysis.

Published: April 2014

AimTo compare survival on different beta‐blockers in heart failure.Methods and resultsWe identified all Danish patients ≥35 years of age who were hospitalized with a first admission for heart failure and who initiated treatment with a beta‐blocker within 60 days of discharge. The study period was 1995–2011. The main outcome was all‐cause mortality and all‐cause hospitalization. Cox proportional hazard models were used to compare survival. The study included 58 634 patients of whom 30.121 (51.4%) died and 46.990 (80.1%) were hospitalized during follow‐up. The mean follow‐up time was 4.1 years. In an unadjusted model carvedilol was associated with a lower mortality [hazard ratio (HR) 0.737, 0.714–0.761] compared with metoprolol (reference) while bisoprolol was not associated with an increased mortality (HR 1.020, 0.973–1.069). In a model adjusted for possible confounders and stratified according to beta‐blocker dosages, patients that received high‐dose carvedilol (≥50 mg daily) had a lower all‐cause mortality risk (HR 0.873, 0.789–0.966) than patients receiving high‐dose (≥200 mg daily) metoprolol (reference). High‐dose bisoprolol (≥10 mg daily) was associated with a greater risk of death (HR 1.125, 1.004–1.261). High‐dose carvedilol was associated with significantly lower all‐cause hospitalization risk (HR 0.842, 0.774–0.915) than high‐dose metoprolol (reference), while high‐dose bisoprolol had insignificantly lower risk than high‐dose metoprolol (HR 0.948, 0.850–1.057).ConclusionsHeart failure patients receiving high‐dose carvedilol (≥50 mg daily) showed significantly lower all‐cause mortality risk and hospitalization risk, compared with other beta‐blockers.

Published: April 2014

AbstractPalladium nanoparticles, prepared by the hydrogenation of Pd(dba)2 in the presence of a tris‐imidazolium iodide as stabilizer, act as an efficient catalyst for Heck and copper‐free Sonogashira reactions with a range of aryl iodides and bromides at 0.2 mol‐% Pd loading. Moreover, we describe a convenient protocol for the fluoride‐free Hiyama coupling of vinylsilanes with aryl iodides that involves the use of sodium hydroxide as promoter in a methanol/water mixture. Under the developed conditions, one‐pot, double Heck and Hiyama–Heck reactions are successfully achieved.
