Extending the dramaturgical framework in marketing: Drama structure, drama interaction and drama content in shopping experiences
Authors: Moisio Risto , Arnould Eric J. 
Published: July 2005

AbstractThe dramaturgical framework in marketing provides a rich theoretical framework for understanding shopping experiences. The purpose of this paper is to extend the current dramaturgical framework on shopping experiences by distinguishing between drama structure, drama interaction and drama content. The extended dramaturgical framework provides a more comprehensive understanding of the ways in which cultural resources, active consumer agency and formal components of shopping performances contribute to shopping experiences.

Dressing for the thrill: An exploration of why women dress up to go shopping
Authors: Johnstone Micael‐Lee , Conroy Denise M. 
Published: July 2005

AbstractThis paper focuses on the pleasurable aspects of shopping from an experiential perspective, ritual behaviour being the focal point. This research adopts an interpretive methodological approach and relies on phenomenological interviews with a range of women to explain how ritual behaviour and ritual artefacts contribute to pleasurable shopping experiences. The findings suggest that the dressing ritual is an important determinant of whether or not the shopping experience will be perceived as pleasant or unpleasant. Equally important, the ritual of dressing was found to play an important role for many of the participants in their maintenance of self. Copyright © 2005 John Wiley & Sons, Ltd.
Thrift shopping: Combining utilitarian thrift and hedonic treat benefits
Authors: Bardhi Fleura , Arnould Eric J. 
Published: July 2005

AbstractThrough an ethnography of shopping that takes place in five thrift stores in a US midwestern town, the authors examine the role of thrift in a shopping process that is both economic and hedonic—‘thrift shopping’. Taking a dialectical perspective on the study of shopping (Sherry, 1990), Miller's (1998) findings on the role of thrift are extended by showing that in the thrift shopping context thrift coexists with treat, and the pursuit of thrift can itself become a hedonic experience. In addition, the authors identify six ways in which consumers practise thrift in thrift shopping and the hedonic benefits that they derive from this money‐saving activity. The findings challenge the traditional frugality perspective of dichotomising thrift and hedonic desire being opposite and contradictory orientations. Copyright © 2005 John Wiley & Sons, Ltd.
Exploring the ‘shopping imaginary’: The dreamworld of women's magazines
Authors: Stevens Lorna , Maclaran Pauline 
Published: July 2005

AbstractThis paper focuses on the consumer imagination and, more specifically, on the imaginary shopping spaces which women's magazines create. It addresses the anticipatory, imaginary and experiential consumption which this medium invites. The paper explores how women's magazines function as ‘dreamworlds’ of shopping; and how contemporary readers consume these imaginary shopping spaces. In order to illustrate what the authors term the ‘shopping imaginary’, they draw on findings from a study of women's experiential consumption of magazines, which show the multifaceted ways around which imaginary consumption is explored and enjoyed by women. The study suggests that women's magazines, like department stores, are spaces that facilitate and celebrate just looking and browsing, and, above all, they are shopping spaces that address the power of the imagination within them.

The future of mall research: Current trends affecting the future of marketing research in malls
Authors: Frost‐Norton Tammie 
Published: July 2005

AbstractThe Marketing Research Association (MRA) Annual Conference in Boston, MA (5–7 June, 2004), held a panel discussion as part of the workshop portion of the conference regarding quantitative research. The panel was made up of: Janet Baldi, Vice President of Data Collection & Data Quality for Rothstein‐Tauber/Directions for Decisions (RTI‐DFD); Jackie Weise, Executive Vice President and Principal for Market Trends, Inc.; Kim Fitzgerald, Manager–Market Research for Hasbro Inc.; and Tammie Frost‐Norton. The moderator of the panel was Wendy Dodek, Moderator for Insight Research & Training. The purpose of the panel discussion was to look at current practices of conducting consumer research in malls, the changes occurring due to decisions by buyers of mall research, the health of mall research and the possibilities for the future of mall research. Current trends show less consumer research being conducted via mall intercept, and more being conducted online and with database pre‐recruited interviewing. The future health of mall research may depend on mall facility owners' reactions to existing problems, and their ability to capitalise on the weaknesses of internet data collection. Stability of mall data collection facilities may come from selecting the best possible mall for strong consumer research, and that may be more important in the future than it has ever been. Discussions from the panellists indicate that mall data collection also would need to return to the basics to ensure timeliness and quality. Mall facility owners need to market the unique strengths of each mall's respondent base. Although the discussion here centres on developments in US mall research, the majority of the findings will be relevant to practitioners of shopping‐centre or high‐street‐based interviewing in the UK and other countries.

The symbolic servicescape: Your kind is welcomed here
Authors: Rosenbaum Mark S. 
Published: July 2005

AbstractThis paper expands Bitner's (1992) servicescape framework by conceptualising the existence of a symbolic servicescape. To date, researchers primarily have explored how consumers respond to physical elements within a consumption setting's built environment, however, commercial establishments have a history of discriminating against ethnic consumers. Thus, ethnic consumers may respond to other environmental elements when formulating marketplace approach/avoidance decisions. This paper reveals that ethnic consumers respond to a symbolic servicescape, defined as objects and artefacts that evoke similar meanings across members of specific ethnic groups. Using photo‐elicitation methodology, the author demonstrates how Jewish and homosexual consumers interpret symbols within consumption settings and how these symbols impact on approach/avoidance behaviour.

Atypical CTSK transcripts and ARNT transcription read‐through into CTSK
Authors: Giraudeau Fabienne S. , Walhin Jean‐Philippe , Murdock Paul R. , Spurr Nigel K. , Gray Ian C. 
Published: July 2005

AbstractThe aryl hydrocarbon receptor nuclear translocator (ARNT) and cathepsin K (CTSK) genes lie in a tandem head‐to‐tail arrangement on human chromosome 1. The two genes are in extremely close proximity; the usual CTSK transcription start site is less than 1.4 kb downstream of the end of the longest reported ARNT transcript. By generating an RT‐PCR product that overlaps both the 3′ end of ARNT and the 5′ end of CTSK, we show that ARNT transcripts may extend through the ARNT–CTSK intergenic region and progress into the CTSK gene. Furthermore, by using quantitative RT‐PCR from several tissues to detect the ARNT expression signature in CTSK introns, we show that ARNT transcripts can read through into CTSK as far as CTSK intron 3, extending approximately 3.7 kb downstream of the end of the longest previously described ARNT mRNA. Given that ARNT and CTSK are expressed in an overlapping range of tissues, ARNT read‐through may have a negative impact on CTSK transcript levels by interfering with CTSK expression. We also present evidence for novel CTSK transcripts following sequence analysis of CTSK‐derived ESTs and RT‐PCR products. These transcripts show alternate 5′ splicing and or 5′ extension and are sometimes initiated from a cryptic alternative promoter which is upstream of the known CTSK promoter and possibly in the 3′ UTR of ARNT.

Authors: Hartman Stefanie , Touchton Greg , Wynn Jessica , Geng Tuoyu , Chong Nelson W. , Smith Ed 
Published: July 2005

AbstractThe pineal gland is the circadian oscillator in the chicken, regulating diverse functions ranging from egg laying to feeding. Here, we describe the isolation and characterization of expressed sequence tags (ESTs) isolated from a chicken pineal gland cDNA library. A total of 192 unique sequences were analysed and submitted to GenBank; 6% of the ESTs matched neither GenBank cDNA sequences nor the newly assembled chicken genomic DNA sequence, three ESTs aligned with sequences designated to be on the Z_random, while one matched a W chromosome sequence and could be useful in cataloguing functionally important genes on this sex chromosome. Additionally, single nucleotide polymorphisms (SNPs) were identified and validated in 10 ESTs that showed 98% or higher sequence similarity to known chicken genes. Here, we have described resources that may be useful in comparative and functional genomic analysis of genes expressed in an important organ, the pineal gland, in a model and agriculturally important organism.

Sensitivity of Transmission Surface Plasmon Resonance (T‐SPR) Spectroscopy: Self‐Assembled Multilayers on Evaporated Gold Island Films
Authors: Doron‐Mor Ilanit , Cohen Hagai , Barkay Zahava , Shanzer Abraham , Vaskevich Alexander , Rubinstein Israel 
Published: July 2005

AbstractThe distance dependence of the localized surface plasmon (SP) extinction of discontinuous gold films is a crucial issue in the application of transmission surface plasmon resonance (T‐SPR) spectroscopy to chemical and biological sensing. This derives from the usual sensing configuration, whereby an analyte binds to a selective receptor layer on the gold film at a certain distance from the metal surface. In the present work the distance sensitivity of T‐SPR spectroscopy of 1.0–5.0 nm (nominal thickness) gold island films evaporated on silanized glass substrates is studied by using coordination‐based self‐assembled multilayers, offering thickness tuning in the range from ∼1 to ∼15 nm. The morphology, composition and optical properties of the Au/multilayer systems were studied at each step of multilayer construction. High‐resolution scanning electron microscopy (HRSEM) showed no apparent change in the underlying Au islands, while atomic force microscopy (AFM) indicated flattening of the surface topography during multilayer construction. A regular growth mode of the organic layers was substantiated by X‐ray photoelectron spectroscopy (XPS). Transmission UV‐visible spectra showed an increase of the extinction and a red shift of the maximum of the SP band upon addition of organic layers, establishing the distance dependence of the Au SP absorbance. The distance sensitivity of T‐SPR spectroscopy can be varied by using characteristic substrate parameters, that is, Au nominal thickness and annealing. In particular, effective sensitivity up to a distance of at least 15 nm is demonstrated with 5 nm annealed Au films. It is shown that intensity measurements, particularly in the plasmon intensity change (PIC) presentation, provide an alternative to the usually measured plasmon band position, offering good accuracy and the possibility of measuring at a single wavelength. The present distance sensitivity results provide the basis for further development of T‐SPR transducers based on receptor‐coated Au island films.
Group‐Selective Ring‐Closing Enyne Metathesis
Authors: Maifeld Sarah V. , Lee Daesung 
Published: July 2005

AbstractThe ring‐closing metathesis (RCM) of dienynes represents a powerful methodology for the construction of mono‐ and bicyclic systems containing 1,3‐diene functionality. Despite its synthetic potential, the utility of dienyne RCM is significantly reduced due to poor group selectivity. To circumvent this shortcoming, several strategies utilizing steric hindrance, electronic variation, relay metathesis and ring‐closure kinetics have been implemented to exert control over the reaction pathways. This article highlights a variety of methods to achieve group‐selective enyne RCM of dienynes.
Curcumin‐induced antiproliferative and proapoptotic effects in melanoma cells are associated with suppression of IκB kinase and nuclear factor κB activity and are independent of the B‐Raf/mitogen‐activated/extracellular signal‐regulated protein kinase pathway and the Akt pathway

Published: July 2005

AbstractBACKGROUNDNuclear factor‐κB (NF‐κB) plays a central role in cell survival and proliferation in human melanoma; therefore, the authors explored the possibility of exploiting NF‐κB for melanoma treatment by using curcumin, an agent with known, potent, NF‐κB‐inhibitory activity and little toxicity in humans.METHODSThree melanoma cell lines (C32, G‐361, and WM 266‐4), all of which had B‐raf mutations, were treated with curcumin, and the authors assessed its effects on viability ((3‐[4,5‐dimethylthiazol‐2‐yl]2,5‐diphenyltetrazolium bromide assay) and apoptosis (flow‐cytometric analysis of annexin V/propidium iodide‐stained cells). Curcumin‐treated cells also were examined for NF‐κB binding activity (electrophoretic mobility shift assay) and for the activity of its upstream regulator, IκB kinase (IKK) (immune complex kinase assay). In addition, relevant signaling, as reflected by B‐Raf kinase activity (kinase cascade assay), and steady‐state levels of activated, downstream effectors, as reflected by mitogen‐activated signal‐regulated protein kinase (MEK), extracellular signal‐regulated protein kinase (ERK), and Akt phosphorylation levels (immunoblots), were assessed.RESULTSCurcumin treatment decreased cell viability of all 3 cell lines in a dose‐dependent manner (50% inhibitory concentration = 6.1–7.7 μM) and induced apoptosis. NF‐κB and IKK were active constitutively in all melanoma cell lines examined, and curcumin, under apoptosis‐inducing conditions, down‐regulated NF‐κB and IKK activities. However, curcumin did not inhibit the activities of B‐Raf, MEK, or ERK, and Akt phosphorylation was enhanced. Furthermore, in the presence of curcumin, the Akt inhibitor 1L‐6‐hydroxymethyl‐chiro‐inositol 2‐[(R)‐2‐O‐methyl‐3‐O‐octadecylcarbonate] no longer suppressed Akt phosphorylation.CONCLUSIONSCurcumin has potent antiproliferative and proapoptotic effects in melanoma cells. These effects were associated with the suppression of NF‐κB and IKK activities but were independent of the B‐Raf/MEK/ERK and Akt pathways. Cancer 2005. © 2005 American Cancer Society.
Tests of radial basis functions in the 3D DRM‐MD
Authors: Natalini Bruno , Popov Viktor 
Published: July 2005

AbstractSeveral global as well as compactly supported radial basis functions were tested in the boundary element dual reciprocity method‐multi domain approach (DRM‐MD) applied to 3D potential problems. Compactly supported radial basis functions (CS‐RBFs) showed the highest accuracy, while the augmented thin plate splines (ATPS) showed the highest consistency in terms of accuracy and convergence for the two examples considered, the Poisson and the advection–diffusion equations. A problem for implementation of the CS‐RBFs is the lack of guidelines in choosing the size of the support, which showed to have large influence on the accuracy and convergence when these types of RBFs are used. The ATPS showed satisfactory accuracy and since its use does not involve any extra parameters, at the moment it is this function that is the choice of the authors for use in the DRM‐MD.

Authors: Tan Song Ting , Wendorff Joachim H. , Pietzonka Clemens , Jia Zhi Hong , Wang Gui Qing 
Published: July 2005

AbstractSuperparamagnetic polymer nanofibers intended for drug delivery and therapy are considered here. Magnetite (Fe3O4) nanoparticles in the diameter range of 5–10 nm were synthesized in aqueous solution. Polymer nanofibers containing magnetite nanoparticles were prepared from commercially available poly(hydroxyethyl methacrylate), PHEMA, and poly‐L‐lactide (PLLA) by the electrospinning technique. Nanofibers with diameters ranging from 50 to 300 nm were obtained. Nanofibers containing up to 35 wt % magnetite nanoparticles displayed superparamagnetism at room temperature. The blocking temperature was about 50 K for an applied field of 500 Oe, and the saturation magnetization was 3.5 emu g−1 and 1.1 emu g−1 for Fe3O4/PHEMA and Fe3O4/PLLA nanofibers, respectively, and depended on the amount of Fe3O4 nanoparticles in the nanocomposites. To test such magnetic nano‐objects for applications as drug carriers and drug‐release systems we incorporated a fluorescent albumin with dog fluorescein isothiocyanate (ADFI).
Microarray analysis of gene expression during epithelial–mesenchymal transformation
Authors: LaGamba Damian , Nawshad Ali , Hay Elizabeth D. 
Published: July 2005

AbstractOne of the most fundamental biological processes in development, as well as a primary mechanism for tumor metastasis, is epithelial–mesenchymal transformation (EMT). To gain a greater understanding of this transition, we have obtained a genomic profile of the critical stages before and during this rapid change in morphology in the developing mouse palate. By isolating the medial edge epithelium of each palatal shelf, we were able to obtain pure gene expression data without contamination from surrounding mesenchymal cells. Our results support the important role of the TGF‐β/Smad signal transduction pathway in the stimulation of EMT by means of up‐regulation of the EMT‐inducing gene, LEF‐1. We document changes in gene expression profiles during palatal adherence and subsequent transformation of the medial edge epithelial seam that suggests a high number of LEF‐1 target genes promote cellular transformation to mesenchyme. These include genes involved in cell adhesion, polarity, cytoskeletal dynamics, migration, and intracellular signaling. This knowledge of the changes in gene expression levels during palatogenesis should lead to a better understanding of the mechanisms of EMT.

Authors: Karabulut Ihsan , Topcu Ali , Yorulmaz Asli , Tekin Aziz , Ozay Dilek Sivri 
Published: July 2005

AbstractHazelnut (Corylus avellana L.) oil was chemically refined using industrial refining conditions. Crude hazelnut oil was obtained by pre‐pressing‐solvent extraction methods and refined by neutralization, bleaching and deodorization in industrial scale. The changes in color, free fatty acids, fatty acid composition, tocopherol and phytosterol contents were determined after each step of refining. The main color change was observed during bleaching. Fatty acid composition, mainly oleic acid (81%), did not change significantly during the process. At the end of the refining, the amounts of total tocopherol and phytosterol decreased from 51.89 to 46.67 mg/100 g and from 168.04 to 141.48 mg/100 g, respectively. The biggest losses of both tocopherols and sterols were observed after neutralization. Deodorization caused a slight decrease in the amount of sterols. α‐Tocopherol (36.19 mg/100 g), β‐tocopherol (9.3 mg/100 g), and γ‐sitosterol (120.28 mg/100 g) were the predominant unsaponifiables in refined hazelnut oil.
Crystallization of cocoa butter with and without polar lipids evaluated by rheometry, calorimetry and polarized light microscopy

Published: July 2005

AbstractIn this investigation, we evaluated the crystallization process of triacylglycerols (TAG) in unrefined cocoa butter (CB) and in CB without polar lipids (CB‐WPL), under non‐isothermal and isothermal conditions. These conditions were obtained by cooling from 80 °C at a cooling rate of 1 °C/min until achieving particular crystallization temperatures (i.e., 18.5 °C, 19.0 °C, 19.5 °C, and 20 °C), at which isothermal crystallization studies were done. Phase shift angle rheograms (δ) showed that the onset of crystallization during the non‐isothermal stage, independently of the crystallization temperature (TCr) used, was 59.8 ± 3.7 °C in CB and 39.5 ± 1.5 °C in CB‐WPL. These results pointed out the nucleating role of phosphatidylcholine (26.53 ± 0.04%) and phosphatidylethanolamine (57.14 ± 0.07%), the main phospholipids present in the CB used in this investigation. Under similar crystallization conditions, differential scanning calorimetry (DSC) provided an onset of crystallization during the non‐isothermal stage of 15.0 ± 0.0 °C in CB‐WPL and of 15.5 ± 0.1 °C in CB. Then, δ rheograms were more sensitive to detect the nucleating role of phospholipids than DSC. Under isothermal conditions, both DSC and δ rheograms showed that shorter times were needed in CB‐WPL to complete crystallization than in CB. In the same way, at all TCr investigated, a higher crystallization rate was achieved in CB‐WPL than in CB, this as measured by the crystallization rate constant (z) of the Avrami equation. These results showed that crystallization of α and β' polymorphs took longer in CB than in CB‐WPL, pointing out that polar lipids delayed the α‐to‐β' polymorphic transition. Additional results confirmed that polar lipids affect the kinetics of TAG crystallization in CB. However, polar lipids do not affect the thermodynamic properties of the crystals [i.e., heat of fusion (δHM), temperature of fusion (TM')], the storage modulus at the end of the crystallization process (i.e., G' of pseudo‐equilibrium), or the mechanism of crystal growth (i.e., the Avrami index, n).
Antioxidant activity of polar extracts from olive oil and olive mill wastewaters: an EPR and photometric study

Published: July 2005

AbstractPolar extracts from olive oil and olive mill wastewaters (OMW) were isolated and examined as direct scavengers of free radicals. In order to evaluate their potent antioxidant capacity, two experimental procedures were undertaken: electron paramagnetic resonance (EPR) in combination with a spin‐trapping technique and a photometric procedure based on the formation of the N,N‐dimethyl‐p‐phenylenediamine colored radical cation (DMPD+.). In the EPR study, free radicals were generated by oxidizing the lipid moiety of low‐density lipoprotein or lecithin micelles by Cu2+. Stable radical spin adducts were produced using the spin trap α‐phenyl‐t‐butylnitrone. The formation of the three‐line EPR signal was inhibited in the presence of compounds with known antioxidant activity or of polar extracts with potent antioxidant activity. The antioxidant activity of polar extracts from olive oil and OMW was also measured using the N,N‐dimethyl‐p‐phenylenediamine (DMPD) colorimetric procedure. The antioxidant capacity of the extracts tested was expressed as trolox equivalents per mg of antioxidant. The extraction procedures of olive oil seem to affect olive oil content in antioxidants and, consequently, the corresponding antioxidant capacity. Tannin‐rich polar extracts isolated from the OMW are much more potent in scavenging free radical formation than polyphenol‐rich polar extracts from olive oil.
