How the Temporal Framing of Energy Savings Influences Consumer Product Evaluations and Choice
Authors: Tangari Andrea Heintz , Smith Ronn J. 
Published: March 2012

ABSTRACTConsumer interest in behavior that is good for the environment is increasing, but actual behavior consistent with this objective has not risen accordingly. This may in part be due to consumers not realizing that their environmentally protective behaviors may have tangible future benefits for them. These studies examine the influence of message frames and a consumer's propensity to think about the future for products that have future benefits. More specifically, these studies examine how consumers respond to temporal frames of savings on product packaging for energy efficient products. Two studies suggest that the temporal framing of savings can influence product choice, purchase intentions, attitudes, and perceptions of savings. The results indicate that future‐oriented consumers are likely to have more positive evaluations when savings are framed in the distant future compared to the near future. In addition, there is a mediating effect of perception of savings. These experiments provide information of interest to marketers and researchers regarding the influence of temporal frames and a consumer's temporal orientation on products that have future benefits.
Asymmetric Effects of Regulatory Focus on Expected Desirability and Feasibility of Embracing Self‐Service Technologies

Published: March 2012

ABSTRACTThis research draws on regulatory focus theory to examine the asymmetric effects of regulatory focus (promotion focus versus prevention focus) on expected desirability and feasibility of using self‐service technologies (SSTs) in a retail setting. To study consumers’ SST trial intention from the perspective of regulatory focus theory, this research first integrates the attributes of SSTs explored in prior studies into a desirability–feasibility framework. The proposed asymmetric effects of regulatory focus (promotion focus versus prevention focus) lie in both scope (on desirability, feasibility, versus both desirability and feasibility) and valence (positive versus negative): The promotion focus facilitates consumers to recognize both desirability (consumption value) and feasibility of using SSTs, whereas the prevention focus inhibits consumers from understanding the feasibility‐related attributes of SSTs. In addition, it is proposed that the promotion focus contributes to the easement of consumers’ technology anxiety, whereas the prevention focus has a reverse effect. Furthermore, expected desirability (consumption value) and feasibility both positively influence consumers’ intention to adopt SSTs, whereas technology anxiety negatively affects consumers’ trial intention. Structural equation modeling is used to test the overall model, and the results support the hypotheses in general.
Understanding Consumer Response to Sponsorship Information: A Resource‐Matching Approach
Authors: Deitz George D. , Myers Susan W. , Stafford Marla R. 
Published: March 2012

ABSTRACTSponsorship of sporting teams and events has become an increasingly popular form of corporate and brand communication. Despite the continued growth of sponsorship spending, the corresponding literature base is highly fragmented and little agreement exists related to the psychological mechanisms underlying response. This paper integrates several prominent sponsorship research streams in promoting a “resource‐matching” perspective of cognitive elaboration and attitude change. This research holds that in the absence of clear functional fit between sponsor and event, identifying a basis for sponsor–event fit is likely to require some degree of cognitive effort. The results indicate stronger social identification with the sponsored event influences the favorability they attribute to sponsor motives and promotes stronger perceptions of fit between the sponsor and the sponsored activity. Further, the results indicate fit perceptions mediate the relationship between attribution and sponsorship response. Consistent with ELM theory, when cognitive resources are insufficient for the complexity of the fit‐matching task, social identification may still act as a peripheral cue in driving a positive affective response to sponsorship information.
Investigating Customer Resistance to Change in Transaction Relationship with anInternet Vendor
Authors: Kim Hee‐Woong , Gupta Sumeet 
Published: March 2012

ABSTRACTMany academics and practitioners have reiterated the importance of online customer retention to ensure long‐term profitability. Consequently, a number of studies have identified various means of customer retention. These studies lay significant emphasis on creating customer loyalty. However, retaining customers, especially in the context ofInternet shopping, is very difficult because of the low costs in comparison and switching. Most of the loyalty programs have also shown disappointing results. This study suggests that by tapping on an individual customer's inclination to resist changes in a transaction relationship, anInternet vendor can achieve customer retention. Using status quo bias theory, this study examines customer resistance to change (CRC) as a means of retaining customers in a transaction relationship with theInternet vendor. The empirical study of anInternet bookstore reveals that trust, relative attractiveness, and switching costs together influenceCRC. The empirical results also show thatCRCand switching costs have positive effects on willingness to pay more. Implications for theory and practice are discussed.
Evaluating Advice: Self‐Presentational Biases between High and Low Self‐Monitors
Authors: Harnish Richard J. , Bridges K. Robert , Krajci Matthew D. 
Published: March 2012

ABSTRACTPrevious research has demonstrated that high and low self‐monitors sought advice from others who shared their underlying motivational dispositions. Here, three studies extend the prior research by exploring how consumers’ underlying motives direct the type of advice offered and how it is evaluated. In Study 1, high and low self‐monitors were asked to evaluate the advice they gave others. As predicted, high self‐monitors rated their advice more favorably than did low self‐monitors. The underlying motivation that caused high self‐monitors to evaluate their advice more positively was investigated in Study 2. Results indicated that high self‐monitors rated their advice higher because it appeared to be meeting a social‐adjustive function (i.e., self‐presentational needs). In Study 3, high and low self‐monitors created an advertisement that featured their advice on dating for a fictitious online matchmaking service. As expected, advertisements created by high self‐monitors contained advice that addressed social‐adjustive needs while those created by low self‐monitors contained advice that addressed value‐expressive needs. The results of these studies suggest that underlying motivations of the individual play an active role in how advice is crafted and evaluated.
Does Private Label Quality Influence Consumers’ Decision on Where to Shop?
Authors: Nies Salome , Natter Martin 
Published: March 2012

ABSTRACTWhen consumers decide where to shop, they take several criteria into account. It is not yet clear whether private label (PL) quality is one of these criteria. It is the intention of this study to shed light on this issue because many retailers have invested heavily into the quality of their PLs. They assume that PLs differentiate a store's assortment and image, which should attract customers to the store. This study examines this assumption by use of a simultaneous equation model that links PL‐specific quality evaluations to perceptions of the image of the associated store as well as to the category‐specific share of store visits. Empirical results for 10 product categories show that PL quality positively affects store image perception, and influences consumers in the decision of where to shop.
Bifurcation buckling from a membrane stress state
Authors: Mang Herbert A. , Höfinger Gerhard 
Published: March 2012

SUMMARYA membrane stress state may be considered as a general stress state in which mechanical constraints have been imposed. Therefore, it would appear that there are mathematical subsidiary conditions for bifurcation buckling from such a stress state. In this work, such conditions are derived in the frame of the Finite Element Method. The basic condition follows from disintegration of the second derivative of the mathematical formulation of the so‐called consistently linearized eigenproblem with respect to a dimensionless load parameter. It is used for deriving another condition, characterized by the vanishing of a particular bilinear form. Linear stability analysis and bifurcation buckling from linear prebuckling paths are two special cases for which this condition is satisfied. Sensitivity analysis of bifurcation buckling of a two‐hinged arch, subjected to a uniformly distributed static load, by varying the geometric form of its axis serves the purpose of non‐trivial verification of the derived condition for the special case of a thrust‐line arch.

Improving mass conservation in simulation of incompressible flows
Authors: Ryzhakov P. , Oñate E. , Rossi R. , Idelsohn S. 
Published: March 2012

SUMMARYWe propose a technique for improving mass‐conservation features of fractional step schemes applied to incompressible flows. The method is illustrated by using a Lagrangian fluid formulation, where the mass loss effects are particularly apparent. However, the methodology is general and could be used for fixed grid approaches. The idea consists in reflecting the incompressibility condition already in the intermediate velocity. This is achieved by predicting the end‐of‐step pressure and using this prediction in the fractional momentum equation. The resulting intermediate velocity field is thus much closer to the final incompressible one than that of the standard fractional step scheme. In turn, the predicted pressure can be used as the boundary condition necessary for the solution of the pressure Poisson equation in case a continuous Laplacian matrix is employed. Using this approximation of the end‐of‐step incompressible pressure as the essential boundary condition considerably improves the conservation of mass, specially for the free surface flows of fluids with low viscosity. The pressure prediction does not require the resolution of any additional equations system. The efficiency of the method is shown in two examples. The first one shows the performance of the method with respect to mass conservation. The second one tests the method in a challenging fluid–structure interaction benchmark, which can be naturally resolved by using the presented approach. Copyright © 2012 John Wiley & Sons, Ltd.

AbstractBackgroundFindings on gender differences in the psychological distress of cancer patients have been inconsistent. The objectives of the current study were to examine whether being a parent differentially modulates anxiety and depression in men and women and to compare whether psychological distress differs in male and female patients with and without children.MethodsThere were 235 patients (77% female, 23% male) with different cancer types included in the group with underage children (age <18 years). The comparison group with no children comprised 85 patients. Psychological distress was assessed via the Hospital Anxiety and Depression Scale within 12 months after first diagnosis or during treatment of metastases.ResultsIn the patient group with underage children, women tended to report more anxiety than men. The comparison with the patient group without children, however, revealed that men were significantly more affected by anxiety when they had children, whereas in women, anxiety ratings did not differ between the groups. Men tended to report more depressive symptoms, but depression was not differentially associated with parenthood. A binary logistic regression showed that in men with cancer, anxiety, as well as depression, was highly related to unemployment. In women, occurrence of metastases as well as suffering from other cancer types than breast cancer was associated with higher ratings of anxiety.ConclusionEven though our findings need to be supported in future investigations using larger sample sizes, they imply that male cancer patients with underage children are in particular need of psychosocial support.

Published: March 2012

ABSTRACTBuilding on African migration as a household survival strategy; urban–rural linkages as critical for migrants' continued engagement with origin communities; reintegration in case of return; and safety net for supplementing precarious urban incomes; we examine the role of family ties in rural origin linkages among 1,693 older migrants living in Nairobi informal settlements. Despite the grim of slum residence, 80% of older migrants in Nairobi slums maintained contact with their rural origin homes during a full year of observation. Family‐related factors, especially members of the nuclear family residing in rural origin, explained 45% of explained linkages. Religion, ethnicity, land ownership at origin, and current health and economic statuses are other key predictors. The patterns and reasons of linkages are consistent with migrants' positive contributions to the upkeep of rural origin households. Our findings are well‐anchored in the larger continental literature that has shown the urban migrant as not a ‘disembedded individual’ but instead part of rural origin collectives. Against the weakness of state safety net system, the study sheds crucial light on the enduring importance of sociocultural networks in people's everyday lives, particularly the importance of family ties for older migrants. To the extent that poor health status, being aged 60 years or older, and long duration of residence in the slums, which are predictors of low propensities to maintain contacts with rural origin, are also indicators of diminished social engagement, policy interventions among the urban poor may need to include efforts to enhance rural origin reintegration of the most‐aged individuals.

AbstractLabel‐free electrical detection of consecutive deoxyribonucleic acid (DNA) hybridization/denaturation by means of an array of individually addressable field‐effect‐based nanoplate silicon‐on‐insulator (SOI) capacitors modified with gold nanoparticles (Au‐NP) is investigated. The proposed device detects charge changes on Au‐NP/DNA hybrids induced by the hybridization or denaturation event. DNA hybridization was performed in a high ionic‐strength solution to provide a high hybridization efficiency. On the other hand, to reduce the screening of the DNA charge by counter ions and to achieve a high sensitivity, the sensor signal induced by the hybridization and denaturation events was measured in a low ionic‐strength solution. High sensor signals of about 120, 90, and 80 mV were registered after the DNA hybridization, denaturation, and re‐hybridization events, respectively. Fluorescence microscopy has been applied as reference method to verify the DNA immobilization, hybridization, and denaturation processes. An electrostatic charge‐plane model for potential changes at the gate surface of a nanoplate field‐effect sensor induced by the DNA hybridization has been developed taking into account both the Debye length and the distance of the DNA charge from the gate surface.
New technique of amorphous metal nanoparticles production by liquid drop breakup in an electron beam
Authors: Gorokhov Maxim , Yavsin Denis , Kozhevin Vladimir 
Published: March 2012

AbstractWe report a new technique of amorphous metal nanoparticles fabrication based on generation of liquid metal microdrops, their charging in electron flux with subsequent drops fission. Fission of charged metal drop occurs when its charge exceeds a critical value given by Rayleigh instability condition. Nanosize droplets, resulted from fission, cool down at extremely high rate to produce amorphous metal nanoparticles. Initial metal microdrops are generated at the end of an anode tip exposed to strong electric field and electron flux focused to the tip. The emitted drops then enter an electron beam where they are charged up to instability and are involved in fission process. To eliminate secondary electron emission (SEE) which can prevent drop charging we used electron beams of low energy. With beam energy properly chosen, SEE coefficient is less then unity for all drop sizes and drop charging up to unstable state is ensured. Granular films consisting of amorphous copper particles 2 nm in size are fabricated by the described technique. The results of atomic force microscopy (AFM) and transmission electron microscopy (TEM) studies of the fabricated films are presented. Possible applications of the fabricated structures related to their unusual properties are considered.
The temporal cascade structure of reanalyses and global circulation models
Authors: Stolle J. , Lovejoy S. , Schertzer D. 
Published: March 2012

AbstractThe spatial stochastic structure of deterministic models of the atmosphere has been shown recently to be well modelled by multiplicative cascade processes; in this paper we extend this to the time domain. Using data from the European Centre for Medium Range Weather Forecasting's (ECMWF) reanalyses (ERA40) and two meteorological models (Global Forecast System and Global Environmental Multiscale), we investigate the temporal cascade structures of the temperature, humidity and zonal wind at various altitudes, latitudes and forecast times. First, we estimate turbulent fluxes from the absolute second‐order time differences, showing that the fluxes are generally very close to those estimated in space at the model dissipation scale; thus validating the flux estimates. We then show that temporal cascades with outer scales typically in the range 5–20 days can accurately account for the statistical properties over the range from 6 h up to 3–5 days. We quantify the (typically small) differences in the cascades from model to model, as functions of latitude, altitude and forecast time. By normalizing the moments by the theoretical predictions for universal multifractals, we investigate the ‘Levy collapse’ of the statistics somewhat beyond the outer cascade limit into the low‐frequency weather regime. Although due to finite size effects and the small outer temporal scale, the temporal scaling range is narrow (12–24 h up to 2–10 days), we compare the spatial and temporal statistics by constructing space‐time (Stommel) diagrams, finding space‐time transformation velocities of 450–1000 km day−1, comparable to those predicted based on the solar energy flux driving the system. This transition time‐scale corresponding to planetary size structures objectively defines the transition from usual weather to a low‐frequency weather regime with much lower variability. Finally, we discuss the implications for ensemble forecasting systems, stochastic parametrization and stochastic forecasting. Copyright © 2012 Royal Meteorological Society
Fusion and inference from multiple data sources in a commensurate space
Authors: Ma Zhiliang , Marchette David J. , Priebe Carey E. 
Published: March 2012

AbstractGiven objects measured under multiple conditions—for example, indoor lighting versus outdoor lighting for face recognition, multiple language translation for document matching, etc.—the challenging task is to perform data fusion and utilize all the available information for inferential purposes. We consider two exploitation tasks: (i) how to determine whether a set of feature vectors represent a single object measured under different conditions; and (ii) how to create a classifier based on training data from one condition in order to classify objects measured under other conditions. The key to both problems is to transform data from multiple conditions into one commensurate space, where the (transformed) feature vectors are comparable and would be treated as if they were collected under the same condition. Toward this end, we studied Procrustes analysis and developed a new approach, which uses the interpoint dissimilarities for each condition. We impute the dissimilarities between measurements of different conditions to create one omnibus dissimilarity matrix, which is then embedded into Euclidean space. We illustrate our methodology on English and French documents collected from Wikipedia, demonstrating superior performance compared to that obtained via standard Procrustes transformation. © 2012 Wiley Periodicals, Inc.

Published: March 2012

ABSTRACTThe traditional equalization technologies expose some shortages while people put forward higher demand to quality of communication system and transmission rate. Single‐carrier frequency‐domain equalization (SC‐FDE) is becoming a research hotspot in wideband wireless communication area because of its special predominance. In recent years, the research on SC‐FDE develops quickly. We take a study on feasibility of building SC‐FDE system by comparing performance with orthogonal frequency division multiplexing. This paper takes a study on a dual‐mode direct decision‐least mean square+modify constant modulus algorithm blind equalization algorithm applied in a single‐carrier system. And then, we build the simulation model of image transmission in SC‐FDE system and get the direct and better result through the comparative analysis of image. Copyright © 2012 John Wiley & Sons, Ltd.
Compressive sensing‐based signal compression and recovery in UWB wireless communication system
Authors: Wu Ji , Wang Wei , Liang Qilian , Wu Xiaorong , Zhang Baoju 
Published: March 2012

ABSTRACTIn this paper, we propose a new compressive sensing‐based compression and recovery ultra‐wideband (UWB) communication system. Compared with the conventional UWB system, we can jointly estimate the channel and compress the data, which can also simplify the design of hardware. No information about the transmitted signal is required in advance as long as the channel follows autoregressive process. As an application example, real‐world UWB signal is collected and processed to evaluate the performance of our proposed system. The compression procedure is so simple that we just multiply random Gaussian or Bernoulli matrix with the original data to capture all the information we want. Simulation results show that the data could be perfectly recovered if the compression ratio does not exceed 2.5:1 when Bernoulli matrix is chosen as the sensing matrix.
