Authors: Linstrom Christopher J. , Silverman Carol A. , Yu Guo‐Pei 
Published: March 2009

AbstractObjectives/Hypothesis:The aim was to examine short‐ and long‐term efficacy of the bone‐anchored hearing aid (BAHA) on adults with single‐sided deafness.Study Design:Prospective investigation.Methods:The outcome measures included the Hearing in Noise Test (HINT), Abbreviated Profile of Hearing Aid Benefit (APHAB), and Single‐Sided Deafness Questionnaire (SSD). The BAHA group comprised seven adults with single‐sided deafness and the control group comprised 20 adults with essentially normal‐hearing sensitivity, bilaterally. The outcome measures were administered in the unaided, directional BAHA, and omnidirectional BAHA conditions after 1 month, 6 months, and 12 months of BAHA use. A repeated measures analysis of variance (ANOVA) model was used to evaluate the data (for the SSD, a nonparametric analog of ANOVA was employed).Results:None of the factors (time, HINT condition, amplification status) or their interactions were significant predictors of change in signal‐to‐noise ratio (SNR) from baseline over time on the HINT. The mean SNR (non–baseline‐subtracted) was significantly lower in the directional BAHA versus the unaided status and in the omnidirectional BAHA versus the unaided status, but only under the noise in front, speech lateralized to the bad ear HINT condition. Significant short‐ and long‐term BAHA benefit was observed on the APHAB (all subscales except Aversiveness) and SSD (all questionnaire items).Conclusions:Our results show short‐ and long‐term efficacy for the BAHA in adults with single‐sided deafness for recognition of speech in noise (noise in front, speech lateralized to the bad ear) and on subjective measures of benefit.

Local delivery of glial cell line–derived neurotrophic factor improves facial nerve regeneration after late repair
Authors: Barras Florian M. , Kuntzer Thierry , Zurn Anne D. , Pasche Philippe 
Published: March 2009

AbstractObjectives/Hypothesis:Facial nerve regeneration is limited in some clinical situations: in long grafts, by aged patients, and when the delay between nerve lesion and repair is prolonged. This deficient regeneration is due to the limited number of regenerating nerve fibers, their immaturity and the unresponsiveness of Schwann cells after a long period of denervation. This study proposes to apply glial cell line‐derived neurotrophic factor (GDNF) on facial nerve grafts via nerve guidance channels to improve the regeneration.Methods:Two situations were evaluated: immediate and delayed grafts (repair 7 months after the lesion). Each group contained three subgroups: a) graft without channel, b) graft with a channel without neurotrophic factor; and c) graft with a GDNF‐releasing channel. A functional analysis was performed with clinical observation of facial nerve function, and nerve conduction study at 6 weeks. Histological analysis was performed with the count of number of myelinated fibers within the graft, and distally to the graft. Central evaluation was assessed with Fluoro‐Ruby retrograde labeling and Nissl staining.Results:This study showed that GDNF allowed an increase in the number and the maturation of nerve fibers, as well as the number of retrogradely labeled neurons in delayed anastomoses. On the contrary, after immediate repair, the regenerated nerves in the presence of GDNF showed inferior results compared to the other groups.Conclusions:GDNF is a potent neurotrophic factor to improve facial nerve regeneration in grafts performed several months after the nerve lesion. However, GDNF should not be used for immediate repair, as it possibly inhibits the nerve regeneration. Laryngoscope, 2009
More power to X‐rays: New developments in X‐ray spectroscopy
Authors: Guo T. 
Published: March 2009

AbstractRecent developments in X‐ray spectroscopy in the last decade are reviewed. A specific emphasis is placed on displaying the strong natural connection between X‐ray spectroscopy and materials science. Brief explanations of several X‐ray spectroscopic methods are given. X‐ray spectroscopic instruments such as table‐top X‐ray sources are discussed in detail, whereas those employing synchrotron and other sources are briefly addressed. The spectroscopic methods and results from materials investigations are reviewed according to their positions in a 3D parameter space of time, length, and energy. New experimental measurements on atoms, molecules, nanomaterials, and bulk materials that include insulators, semiconductors, metals and magnetic materials using both static and time‐resolved methods are reviewed.
Consumer decision making and variety of offerings: The effect of attribute alignability
Authors: Herrmann Andreas , Heitmann Mark , Morgan Robert , Henneberg Stephan C. , Landwehr Jan 
Published: March 2009

AbstractIn recent years, many companies have considerably increased their number of offering varieties. The underlying rationale for such product strategies is substantiated by the belief that assortment proliferation would better satisfy customers' diverse preferences. However, empirical evidence exists suggesting that if there are too many varieties to choose from, customers sometimes either refrain from making a purchase at all, or else resort to simple selection heuristics. This article approaches the issue of assortment variety from a decision‐theoretical perspective, by positing circumstances under which expanding the number of varieties will positively or negatively affect consumer behavior. Herein, the concept of attribute alignability provides explanatory potential. Two experimental studies are presented which analyze the effect of the number of product varieties on customers' decision‐making behavior by means of manipulating the choice settings in a virtual car configurator. It can be shown that whether the product attributes in question are alignable or nonalignable is the decisive factor in explaining customer decision making under variety. Furthermore, “pseudo‐alignability”is achieved easily via the relabeling of product options. These findings yield concrete managerial insights for the customer‐oriented design of product lines consisting of a basic product and several varieties derived from it. ©2009 Wiley Periodicals, Inc.
Selecting the right cause partners for the right reasons: The role of importance and fit in cause‐brand alliances
Authors: Lafferty Barbara A. 
Published: March 2009

AbstractCause‐brand alliances (CBAs) are becoming a routine strategy to enhance the image of the brand and the cause and to encourage brand sales. This research conducted two studies to evaluate importance and fit as selection criteria for the cause partner. Study 1 evaluated the relative importance of a cause on attitudes and purchase intent for a familiar versus an unfamiliar brand. Results suggested that importance of the cause had an effect on attitudes and purchase intent for an unfamiliar brand but not for a familiar brand. Based on an unexpected finding in Study 1, a second study was conducted that addressed the issue of cause–brand fit. Results show that perceptions of logical fit between the cause and the brand does not have an effect for either the familiar or unfamiliar brand. These findings suggest that the importance of the cause may be a more relevant criterion for optimizing a CBA for an unfamiliar brand but, unlike other forms of alliances and contrary to popular anecdotal belief, perceptions of fit may not be relevant for either familiar or unfamiliar brand. ©2009 Wiley Periodicals, Inc.
The brand anchoring effect: A judgment bias resulting from brand awareness and temporary accessibility
Authors: Esch Franz‐Rudolf , Schmitt Bernd H. , Redler Joern , Langner Tobias 
Published: March 2009

AbstractFollowing the Selective Activation, Reconstruction, and Anchoring (SARA) and consumer‐based brand equity models, high awareness brands are expected to serve as anchors for forming impressions of co‐branded entities. Comparing the brand personality profiles of fictitious brand alliances with high and low awareness brands, the brand anchoring effect is found in Studies 1 and 2. Moreover, Study 3 shows that the effect generalizes to specific brand characteristics and results from making brand‐related information more available. Future research on brand awareness and on the brand anchoring effect is discussed. © 2009 Wiley Periodicals, Inc.
Spectral‐spatial pulse design for through‐plane phase precompensatory slice selection in T‐weighted functional MRI

Published: March 2009

AbstractT‐weighted functional MR images suffer from signal loss artifacts caused by the magnetic susceptibility differences between air cavities and brain tissues. We propose a novel spectral‐spatial pulse design that is slice‐selective and capable of mitigating the signal loss. The two‐dimensional spectral–spatial pulses create precompensatory phase variations that counteract through‐plane dephasing, relying on the assumption that resonance frequency offset and through‐plane field gradient are spatially correlated. The pulses can be precomputed before functional MRI experiments and used repeatedly for different slices in different subjects. Experiments with human subjects showed that the pulses were effective in slice selection and loss mitigation at different brain regions. Magn Reson Med 61:1137–1147, 2009. © 2009 Wiley‐Liss, Inc.

Published: March 2009

AbstractIn this article, we consider the k‐edge connected subgraph problem from a polyhedral point of view. We introduce further classes of valid inequalities for the associated polytope and describe sufficient conditions for these inequalities to be facet defining. We also devise separation routines for these inequalities and discuss some reduction operations that can be used in a preprocessing phase for the separation. Using these results, we develop a Branch‐and‐Cut algorithm and present some computational results. © 2009 Wiley Periodicals, Inc. NETWORKS, 2010

Published: March 2009

AbstractBackground: Adjuvant therapy improves breast cancer survival but is underutilized by Black women. Few interventions have addressed this problem. This preliminary report describes the process we used to develop a decision‐support intervention for Black women eligible for adjuvant therapy. Aims were to use qualitative methods to describe factors that influence Black women's adjuvant therapy decisions, use these formative data to develop messages for a treatment decision‐support intervention, and pilot test the acceptability and utility of the intervention with community members and newly diagnosed women.Methods: Thirty‐four in‐depth interviews were conducted with breast cancer patients in active treatment, survivors and cancer providers to gather qualitative data. Participant ages ranged from 38 to 69 years. A cultural framework was used to analyze the data and to inform intervention messages. Most women relied on their providers for treatment recommendations. Several women reported problems communicating with providers and felt unprepared to ask questions and discuss adjuvant treatment options. Other factors related to treatment experiences were: spiritual coping, collectivism and sharing breast cancer experiences with other Black survivors.Results: Using these formative data, we developed an intervention that is survivor‐based and includes an in‐person session which incorporates sharing personal stories, communication skills training and decision support. Intervention materials were reviewed by community members, researchers/clinicians and patients newly diagnosed with breast cancer.Conclusion: Patients reported satisfaction with the intervention and felt better prepared to talk with providers. The intervention will be tested in a randomized trial to enhance decision support and increase use of indicated adjuvant treatment. Copyright © 2009 John Wiley & Sons Ltd.

AbstractBACKGROUNDChronic intra‐prostatic inflammation and obesity are thought to influence prostate carcinogenesis. Thus, variants in genes in these pathways could be associated with prostate cancer risk.METHODSWe genotyped 17 common single nucleotide polymorphisms (SNPs) in RNASEL, TLR4, IL1B, IL6, IL8, IL10, TNF, CRP, ADIPOQ, LEP, PPARG, and TCF7L2 in 258 white prostate cancer cases and 258 matched controls nested in CLUE II. Single‐locus analyses were conducted using conditional logistic regression. TagSNPs were selected in IL10, CRP, and TLR4 and haplotype analyses were done.RESULTSThe A allele of IL10 −1082G>A (rs1800896), known to result in lower levels of this anti‐inflammatory cytokine, was positively associated with risk (AG vs. GG, OR = 1.69, 95% CI: 1.10–2.60; AA vs. GG, OR = 1.81, 95% CI: 1.11–2.96; P
trend = 0.02). Associations of IL10 haplotypes with prostate cancer were explained by high linkage disequilibrium between two tagSNPs (rs1800890 and rs3024496) and −1082G>A. A TLR4 candidate SNP (rs4986790; AG/GG vs. AA, OR = 0.60, 95% CI: 0.33–1.08; Ptrend = 0.09), known to have decreased expression and be associated with lower circulating levels of inflammatory mediators, and tagSNP (rs10116253; CC vs. TT, OR = 3.05, 95% CI: 1.11–8.41), but not haplotypes, were associated with risk. None of the other candidate SNPs or haplotypes was statistically significantly associated with risk.CONCLUSIONOur prospective study suggests that genetic variation in IL10 and possibly TLR4 is associated with prostate cancer risk. Although none of the SNPs in the obesity genes tested was associated, this does not rule out a complex role of obesity and its metabolic consequences in prostate cancer etiology.

AbstractBACKGROUNDA phase I/II trial was conducted to assess feasibility and tolerability of tumor associated antigen peptide vaccination in hormone sensitive prostate carcinoma (PC) patients with biochemical recurrence after primary surgical treatment.METHODSNineteen HLA‐A2 positive patients with rising PSA without detectable metastatic disease or local recurrence received 11 HLA‐A*0201‐restricted and two HLA class II synthetic peptides derived from PC tumor antigens subcutaneously for 18 months or until PSA progression. The vaccine was emulgated in montanide ISA51 and combined with imiquimod, GM‐CSF, mucin‐1‐mRNA/protamine complex, local hyperthermia or no adjuvant. PSA was assessed, geometric mean doubling times (DT) calculated and clinical performance monitored.RESULTSPSA DT of 4 out of 19 patients (21%) increased from 4.9 to 25.8 months during vaccination. Out of these, two patients (11%) exhibited PSA stability for 28 and 31 months which were still continuing at data cut‐off. One patient showed no change of PSA DT during vaccination but decline after the therapy. Three patients had an interim PSA decline or DT increase followed by DT decrease compared to baseline PSA DT. Three of the responding patients received imiquimod and one the mucin‐1‐mRNA/protamine complex as adjuvant; both are Toll‐like receptor‐7 agonists. Eleven (58%) patients had progressive PSA values. The vaccine was well tolerated, and no grade III or IV toxicity occurred.CONCLUSIONMulti‐peptide vaccination stabilized or slowed down PSA progress in four of 19 cases. The vaccination approach is promising with moderate adverse events. Long‐term stability delayed androgen deprivation up to 31 months. TLR‐7 co‐activation seems to be beneficial.

Published: March 2009

AbstractOrthorhombic (O) and tetragonal (T) modifications of TlInS2 were grown by sulfur vapor annealing of monoclinic (M) crystals. Lattice parameters and syngony of the grown crystals were determined from X‐ray investigations (Laue, Weissenberg, rocking crystal and powder diffractions). The lattice parameters a = 6.88 Å, b = 14.04 Å, c = 4.02 Å, Z = 4 and a = b = 7.76 Å, c = 26.6 Å, Z = 20 as well as space groups (SG), P212121 and P41212 were ascribed to O and T modifications, correspondingly. The transition of M‐crystals to O‐ or T‐phase takes place through the intermediate disordered state of M‐phase in which the unit packets with c ≈ 15 Å are randomly positioned along the c‐axis. From photoconductivity (PC) edge it was found that the band gap of O‐TlInS2 (Eg = 2.52 ± 0.01 eV) is slightly higher whereas that of T‐TlInS2 (Eg = 1.87 ± 0.01 eV) is noticeably lower than the band gap of M‐TlInS2.

Published: March 2009

AbstractEpitaxial thin films of CuIn1‐xGaxS2 (0 ≤ x ≤ 1) were grown on single‐crystalline (111)cub‐oriented silicon substrates by means of molecular beam epitaxy from elemental sources. Employing reflection high energy electron diffraction and Rutherford backscattering spectroscopy the twinning characteristics and the composition of the films were determined, respectively. X‐ray diffraction measurements in transmission geometry were performed to determine the lattice mismatch to the substrate. The degree of twinning of the epitaxial films shows a highly non‐linear dependence on their gallium content x. The transition point between high twinning regime (low gallium content) and low twinning regime (high gallium content) is at xt = 0.74. The twinning characteristics are discussed and compared to lattice mismatch and metastable ordering types. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Published: March 2009

AbstractThe photoluminescence analysis of CdS/CdTe interface layer of CdS/CdTe heterojunction has been carried out in the 15‐100 K temperature range. An attempt to correlate observed PL features with the CdSx Te1–x layer presence at the interface of the heterojunctions was made.It is assumed the 1.525 eV band has an excitonic origin and 1.37X PL band is a characteristic impurity band due to CdSTe layer. Comparative plots showing SnO2/CdTe PL spectra are given as well. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Analysis of bound‐exciton emissions of CuInS2 crystals

Published: March 2009

AbstractThe time‐resolved photoluminescence of excitons in bulky crystalline CuInS2 grown by the Hot‐Press method is investigated. The spectra show the main peak at 1.510 eV on which we focus in this work and higher‐energy‐side tail. From the excitation intensity dependence of the emission intensity, the emission at 1.510 eV is attributed to the bound exciton and the charge state of defect center associated with the bound exciton is most likely to be ionized. The decay of the emission shows single‐exponential curve with decay‐time constant of 126 ps. According to the binding energy dependence of the emission lifetime of the bound excitons, we estimate that the emission is dominated by nonradiative recombination or relaxation to lower states. We also discuss the origin of defects associated with the bound exciton and assigned it to be S‐vacancy as a donor center. The origin of other defects binding excitons is speculated.

On t and EWMA t charts for monitoring changes in the process mean
Authors: Zhang Lingyun , Chen Gemai , Castagliola Philippe 
Published: March 2009

AbstractThe performance of an X‐bar chart is usually studied under the assumption that the process standard deviation is well estimated and does not change. This is, of course, not always the case in practice. We find that X‐bar charts are not robust against errors in estimating the process standard deviation or changing standard deviation. In this paper we discuss the use of a t chart and an exponentially weighted moving average (EWMA) t chart to monitor the process mean. We determine the optimal control limits for the EWMA t chart and show that this chart has the desired robustness property. Copyright © 2009 John Wiley & Sons, Ltd.
Some results on the variogram in time series analysis
Authors: Khachatryan Davit , Bisgaard Søren 
Published: March 2009

AbstractData used for monitoring and control of industrial processes are often best modeled as a time series. An important issue is to determine whether such time series are stationary. In this article we discuss the variogram—a graphical tool for assessing stationarity. We build on previous work and provide further details and more general results including analytical structures of variogram for various non‐stationary processes, and illustrate with a number of examples of variograms using standard data sets from the literature and simulated data sets.
