AbstractAlthough previous research has indicated an elevated prevalence of posttraumatic stress disorder (PTSD) and other mental health problems among veterans of Operations Iraqi Freedom and Enduring Freedom following deployment, most of this research has been cross‐sectional and has focused on a limited range of military groups and outcome criteria. This investigation was a longitudinal study of U.S. Air Force security forces assigned to a year‐long high‐threat ground mission in Iraq to determine the degree to which airmen's emotional and behavioral health and committed relationships were adversely impacted by an extended deployment to a warzone. Participants were a cohort of 164 security forces airmen tasked to a 365‐day deployment to train Iraqi police. Airmen completed study measures both prior to and 6–9 months following deployment. Rates of deterioration in individual and interpersonal adjustment were both significant and medium to large in magnitude of effect, d = 0.43 to 0.90. Results suggest that the negative effects of deployment are related to levels of traumatic experiences and do not spontaneously remit within the first 6–9 months following return from deployment—particularly among those service members having relatively lower levels of social support.
The Effect of Requests for Positive Evaluations on Customer Satisfaction Ratings
Authors: Jones Michael A. , Taylor Valerie A. , Reynolds Kristy E. 
Published: January 2014

ABSTRACTIn order to focus service employees’ attention on delivering high levels of customer satisfaction, many companies directly reward (or punish) employees who deliver high (low) levels of satisfaction as reported in companies’ formalized satisfaction measurement processes. As a result, many frontline service employees attempt to influence their customers’ satisfaction evaluation by specifically asking them for positive ratings on surveys completed after the service encounter. Using psychological reactance theory, this research considers the impact of requests for positive evaluations on customers’ satisfaction and future intentions. The results indicate that customers who were asked to provide a positive evaluation actually report lower levels of satisfaction compared to customers who were not asked. The results also indicate that the request for positive evaluation has a negative influence on customers’ repurchase intentions and positive word‐of‐mouth intentions, but only for customers who had a more internal locus of control compared to those with a more external locus of control.
Using Polynomial Regression Analysis and Response Surface Methodology to Make a Stronger Case for Value Congruence in Place Marketing
Authors: Zenker Sebastian , Gollan Tobias , Van Quaquebeke Niels 
Published: January 2014

ABSTRACTValues are an important concept in marketing because they comprise part of peoples’ identity and can thus help marketers separate and target different audiences. Unsurprisingly, places and their marketing initiatives increasingly try to appeal to (potential) residents’ identity by communicating core values. While the notion of value congruence is not novel, most empirical methods in marketing to date only account for the degree rather than the level of congruence. To address this issue, the present article utilizes polynomial regression and response surface methodology (Edwards & Parry, ) in the context of place marketing. Accordingly, the first study shows that the perceived congruence of residents’ own values and the values of stereotypical city inhabitants significantly affect residents’ feelings about their own cities (N = 1257), but with different effects for different values and levels of congruence. This finding holds not only for popular target groups such as the “creative class” but also across all groups. The second study (N = 449) shows that city slogans can effectively communicate specific values and that value congruence leads to a more positive evaluation of the city brand. Finally, the article discusses the benefits of differentiating between levels of congruence both in marketing research in general, and place brand management in particular.
Exploring Attitudes and Affiliation Intentions toward Consumers Who Engage in Socially Shared Superstitious Behaviors: A Study of Students in the East and the West
Authors: Wang Di , Oppewal Harmen , Thomas Dominic 
Published: January 2014

ABSTRACTExisting literature on superstitious beliefs focuses on consumer purchasing behavior. However, little is known about how superstition‐based consumption behaviors are socially perceived. This paper investigates students’ attitudes toward consumers who engage in socially shared superstitious behaviors. Two studies show that students from Eastern and Western countries have negative attitudes and lower affiliation intentions toward consumers engaging in socially shared superstitious behaviors. As predicted by social judgment theory, this effect is driven by perceived low competence but not by perceived warmth. These negative attitudes and lower affiliation intentions are moderated by the student's superstitiousness. The managerial implications of social perceptions regarding consumer superstitious behavior are discussed.
Effects of Sponsorship Disclosure Timing on the Processing of Sponsored Content: A Study on the Effectiveness of European Disclosure Regulations
Authors: Boerman Sophie C. , van Reijmersdal Eva A. , Neijens Peter C. 
Published: January 2014

ABSTRACTThis study investigates whether the timing of sponsorship disclosure affects viewers’ processing of sponsored content, and whether a disclosure influences the persuasive effect of the sponsored content. A model is proposed in which sponsorship disclosure enhances the recognition of sponsored television content as advertising, which leads to critical processing of the sponsored content. Ultimately, this negatively affects the attitude toward the brand in the sponsored content. This model was supported, but only when the disclosure was displayed prior to or concurrent with the sponsored content. These effects were not found for a sponsorship disclosure shown at the end of the program after the sponsored content. Theoretically, the findings emphasize the importance of disclosure timing. A disclosure displayed prior to or concurrent with the sponsored content, primes the sponsored content and provides sufficient processing time, so viewers recognize the content as advertising and can process it critically. In addition, the findings show that persuasion knowledge and critical processing are important underlying mechanisms for the effect of sponsorship disclosure on brand attitude. Regarding the practical implications for legislators and advertisers, this research demonstrates that sponsorship disclosure can make viewers aware of the sponsored content in television programs. Furthermore, this changes the processing of sponsored content and can also ultimately lead to resistance against persuasion.
How Visual Brand Identity Shapes Consumer Response
Authors: Phillips Barbara J. , McQuarrie Edward F. , Griffin W. Glenn 
Published: January 2014

ABSTRACTMost brands are represented visually in print advertisements, and these visual representations must consistently identify the brand to the consumers who encounter it. At the same time, some of the particular visual elements used to represent the brand must change over time, because it is not acceptable to run the same ad year after year without refreshing its visual content. To explore these issues, a qualitative exploration was conducted with ad agency art directors and ordinary consumers. The focus was the criteria used by each group to determine when changes in the visual representation of the brand succeed, by staying consistent with the brand's identity, or fail, by violating expectations. Professionals, with their greater aesthetic sensitivity, had a more narrow latitude of acceptance for changes. A follow‐up experiment with consumers showed that aesthetically aware consumers were likewise more sensitive to alterations in visual brand identity than consumers for whom aesthetics were not central. Results are interpreted in terms of assimilation effects and degree of incongruity along with the moderating effect of aesthetic skill.
Preparation of Functional Polyamine Scaffolds via Mitsunobu Post‐Polymerization Modification Reactions
Authors: Kakuchi Ryohei , Theato Patrick 
Published: January 2014

A Mitsunobu reaction of trifluoroacetamide (TFA amide) and alcohols is used in a post‐polymerization modification process. The reaction is conducted on polystyrene (PSt) bearing 20 mol% TFA amide groups with 4‐methyl benzyl alcohol in the presence of a N,N,N′,N′‐tetramethylazodicarboxamide and tributylphosphine as mediators. The Mitsunobu reaction on polymer proceeds efficiently, as confirmed by the obvious precipitation generation during the reaction and the conversion of TFA amide moiety reached 88.6% confirmed by 19F NMR measurement, yielding PSt bearing tertiary TFA amide moieties. The obtained polymers featuring tertiary TFA amide moieties are deprotected in the presence of tetrabutylammonium hydroxide as a base to afford corresponding polymers featuring functionalized polyamine scaffolds with 92.5% conversion. In addition, the precise structural assignment is proven by synthesis and analysis of the model monomeric compounds and the respective model polymers.

Numerical inversion of laplace transform via wavelet in partial differential equations
Authors: Hsiao Chun‐Hui 
Published: January 2014

This article presents a rational Haar wavelet operational method for solving the inverse Laplace transform problem and improves inherent errors from irrational Haar wavelet. The approach is thus straightforward, rather simple and suitable for computer programming. We define that P is the operational matrix for integration of the orthogonal Haar wavelet. Simultaneously, simplify the formulae of listing table (Chen et al., Journal of The Franklin Institute 303 (1977), 267–284) to a minimum expression and obtain the optimal operation speed. The local property of Haar wavelet is fully applied to shorten the calculation process in the task.The operational method presented in this article owns the advantages of simpler computation as well as broad application. We still can obtain satisfying solution even under large matrix. Moreover, we do not have numerically unstable problems. © 2013 Wiley Periodicals, Inc.

AbstractObjectiveIn children, CNS‐directed cancer therapy is thought to result in decreased cerebral white matter volumes (WMV) and subsequent neurocognitive deficits. This study was designed as a prospective validation of the purported reduction in WMV, associated influential factors, and its relationship to neurocognitive deficits in a very large cohort of both acute lymphoblastic leukemia (ALL) and malignant brain tumors (BT) survivors in comparison to an age similar cohort of healthy sibling controls.ProceduresThe effects of host characteristics and CNS treatment intensity on WMV were investigated in 383 childhood cancer survivors (199 ALL, 184 BT) at least 12 months post‐completion of therapy and 67 healthy siblings that served as a control group. t‐Tests and multiple variable linear models were used to assess cross‐sectional WMV and its relation with neurocognitive function.ResultsBT survivors had lower WMV than ALL survivors, who had less than the control group. Increased CNS treatment intensity, younger age at treatment, and greater time since treatment were significantly associated with lower WMV. Additionally, cancer survivors did not perform as well as the control group on neurocognitive measures of intelligence, attention, and academic achievement. Reduced WMV had a larger impact on estimated IQ among females and children treated at a younger age.ConclusionsSurvivors of childhood cancer that have undergone higher intensity therapy at a younger age have significantly less WMV than their peers and this difference increases with time since therapy. Decreased WMV is associated with significantly lower scores in intelligence, attention, and academic performance in survivors. Pediatr Blood Cancer 2014;61:1074–1079. © 2014 Wiley Periodicals, Inc.

ABSTRACTIntroductionLow first‐trimester serum concentrations of hyperglycosylated human chorionic gonadotrophin (hCG‐h) predict later preeclampsia. We studied whether serum hCG‐h at 14–17 weeks of pregnancy also predicts preeclampsia alone or combined with placental growth factor (PlGF) and soluble vascular endothelial growth factor 1 (sVEGFR‐1).MethodsWe conducted a nested case–control study comprising 55 women with subsequent preeclampsia, 21 with gestational hypertension, 30 with a small‐for‐gestational‐age infant, and 83 controls. Serum concentrations of hCG‐h, proportion of hCG‐h to hCG (%hCG‐h), PlGF, and sVEGFR‐1 were converted to multiples of the medians (MoMs) adjusted for gestational age.ResultsConcentrations of hCG‐h or %hCG‐h did not differ between women with subsequent preeclampsia and controls. In women with subsequent preeclampsia, PlGF was lower (0.62 MoM) than in controls (P < 0.001). In receiver‐operating characteristics curve analysis for the prediction of preeclampsia, the area under the curve for hCG‐h or %hCG‐h was not significantly different from 0.5, whereas that for PlGF was 0.746 (95% confidence interval, 0.656–0.836; P < 0.001). Combining hCG‐h or %hCG‐h with PlGF did not improve the prognostic value.ConclusionsSerum hCG‐h did not improve prediction of preeclampsia in the second trimester. © 2014 John Wiley & Sons, Ltd.
YieldOpt, a model to predict the power output and energy yield for concentrating photovoltaic modules
Authors: Steiner Marc , Siefer Gerald , Hornung Thorsten , Peharz Gerhard , Bett Andreas W. 
Published: January 2014

AbstractIn this work, we discuss three empirical models and introduce one more detailed model named YieldOpt. All models can be used to calculate the power output and energy yield of concentrating photovoltaic (CPV) modules under different ambient conditions. The YieldOpt model combines various modeling approaches: simple model of the atmospheric radiative transfer of sunshine for the spectral irradiance, a finite element method for thermal expansion, ray tracing for the optics, and a SPICE network model for the triple‐junction solar cell. YieldOpt uses a number of constant and variable input parameters, for example, the external quantum efficiency of the cells, the temperature‐dependent spectral optical efficiencies of the optics, the tracking accuracy, the direct normal irradiance, the aerosol optical depth, and the temperature of the lens and the solar cell. To verify the accuracy of the models, the I‐V characteristics of five CPV modules have been measured in a 10‐min interval over a period of 1 year in Freiburg, Germany. Four modules equipped with industrial‐standard lattice‐matched triple‐junction solar cells and one module equipped with metamorphic triple‐junction solar cells are investigated. The higher accuracy of YieldOpt compared with the three empirical models in predicting the power output of all five CPV modules during this period is demonstrated. The energy yield over a period of 1 year was predicted for all five CPV modules with a maximum deviation of 5% by the three empirical models and 3% by YieldOpt.

Luminescent down‐shifting experiment and modelling with multiple photovoltaic technologies

Published: January 2014

AbstractLuminescent down shifting (LDS) is a viable way for improving the short‐wavelength response of many photovoltaic technologies, such as cadmium telluride, copper‐indium‐gallium‐(di)selenide and multi‐crystalline silicon solar cells. In this work, we compare the experimental performance of LDS layers fabricated with six organic dyes—both alone and in mixtures—and two polymers with the theoretical predictions obtained by three different approaches: ray‐tracing simulations and two novel theoretical models. The first model is an analytical description of the LDS process and can reproduce the external quantum efficiency of the solar cell with LDS. The second one is based on a collection of figures of merit that address a desired property of the LDS. The three methods show an excellent agreement with the experimental results in the predicted variation of the short‐circuit current (to within 0.5% in most cases) and help to understand the key factors that influence the performance of LDS, such as the optical coupling, surface roughness and scattering or edge losses. This agreement, regardless of the materials used for LDS and the underlying PV technology, not only supports the validity of the models but also suggests this theoretical formalism as a tool for designing optimised LDS layers in the future.

Synthesis of anionic carbosilane dendrimers via “click chemistry” and their antiviral properties against HIV
Authors: Arnáiz Eduardo , Vacas‐Córdoba Enrique , Galán Marta , Pion Marjorie , Gómez Rafael , Muñoz‐Fernández MA Ángeles , de la Mata F. Javier 
Published: January 2014

ABSTRACTThe synthesis and characterization of four families of anionic carbosilane dendrimers bearing carboxylate, phosphonate, naphthylsulfonate, and sulfate terminal groups prepared by cycloaddition of azide–alkyne catalyzed by copper (CuAAC) are presented here. For the preparation of these anionic carbosilane dendrimers, two strategies starting from azide‐terminated carbosilane dendrimers were followed: (i) click coupling of neutral alkynes followed by derivatization into anionic moieties or (ii) click coupling of anionic alkynes. Both strategies require different reaction conditions in order to accommodate the different substrate polarities. These anionic dendrimers, in general, do not present cell toxicity in vitro until concentration up to 20 µM. Therefore, they can be used in inhibition experiments in concentrations below this limit. We have observed that dendrimers bearing phosphonate groups possess poor anti‐HIV capabilities in vitro in PBMCs, while carboxylate dendrimers can reduce HIV infection levels moderately. On the other hand, sulfate and naphthylsulfonate dendrimers are powerful anti‐HIV agents and their antiviral activity is generation and concentration dependent. © 2014 Wiley Periodicals, Inc. J.

ABSTRACTPolyhydroxyurethane bearing silicone backbone was prepared by polyaddition of silicone diamines with a bifunctional five‐membered cyclic carbonate prepared from the corresponding diepoxide and CO2. Polymerization in propylene glycol methyl ether acetate proceeded smoothly, and polymers could be obtained in high yields under appropriate conditions. The introduced silicone moieties improved the hydrophobicity and lowered the glass transition temperature keeping thermal stability. © 2014 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

“What Motivates Her”: Motivations for Considering Labial Reduction Surgery as Recounted on Women's Online Communities and Surgeons' Websites
Authors: Zwier Sandra 
Published: January 2014

Abstract

Introduction
Increasing numbers of women are seeking labial reduction surgery. We studied the motivations for considering labial reduction surgery as recounted on women's online communities and surgery provider's websites.

Aims
The study analyzed motivations for considering labial reduction surgery expressed by women on online communities, looked at the role of the women's age and nationality, compared findings with motivations indicated on the websites of an international sample of surgery providers, and identified similarities to and differences from what is known from extant studies.

Methods
Quantitative content analysis of the posts of 78 American, British, and Dutch women on online communities, and 40 international surgery providers' websites about labial reduction surgery was conducted.

Main Outcome Measures
Main outcome measures concerned the incidence and prominence of different motivational categories (functional/emotional and discomfort/enhancement related). Differences in motivations as a function of age, national background, and women's vs. surgeons' stated motivations were tested.

Results
Emotional discomfort regarding self-appearance and social and sexual relationships was found to be the most frequent and most prominent motivation for considering labial reduction surgery on women's online communities, regardless of age and national background. Functional discomfort and desired emotional enhancement ranked second. Very few age or national differences were found. The surgeons' websites recognized functional discomfort more and elaborated upon emotional issues in sexual relationships less than members of the online communities.

Conclusions
Feelings of emotional and psychosexual distress in addition to functional distress are a highly prevalent motivation among women considering labial reduction surgery. Emotional distress appears to be greater and more freely emphasized when women communicate on online communities, while functional issues appear to receive greater notice on surgery provider's websites.
