Purchase Behavior and Psychophysiological Responses to Different Price Levels
Authors: Somervuori Outi , Ravaja Niklas 
Published: April 2013

ABSTRACTThe aim of the study was to examine emotional processes when product prices for different brands were changed. In a within‐subjects design, the participants were presented purchase decision trials with 14 different products (seven private label and seven national brand products) whose price levels were changed while their facial electromyography (EMG) and electrodermal activity were recorded. The results suggest that low prices and national brand products induce higher positive emotions indexed with zygomatic EMG compared to high prices and private label products. Also, positive emotions are related to greater purchase intent. Naturally, a low price has also a direct positive influence on purchase intent. However, the involvement of emotions and the influence that price and brand have on elicitation of emotions may be one explanation for consumers’ varying purchase behavior. The results highlight the importance of emotional factors in pricing research and support the usefulness of psychophysiological measures in the consumer research.

Published: April 2013

ABSTRACTThis study investigates the influence of bi‐ and multilingual product packaging on product evaluation. Study 1 compared product evaluations of the same product in an English‐only (English), English‐Spanish (bilingual), and English‐Spanish‐French (trilingual) packaging. The bilingual product received the lowest evaluation. Adding French mitigated this effect as did attributing a relatively high price (vs. a low price) to the product. Study 2 investigated the drivers of the culture of targeting effect and found that whether one believes that Hispanics buy lower quality products was one of the drivers.
Task‐Relationship‐Self: A Framework for Understanding Service Encounter Behaviors

Published: April 2013

ABSTRACTResearch conducted over past decades has investigated selected service encounter behaviors from either a customer or service provider perspective. However, a comprehensive, dual‐perspective framework is lacking. Such a framework is needed to organize knowledge of these behaviors, and thereby provide structure, clarity, and parsimony to the field. This paper describes a three‐tier framework of service encounter behavior that was developed by applying grounded theory principles to interviews with customers, service employees, and other stakeholders. These informants described many ways in which they behave when executing service exchanges, dealing with service difficulties, and managing themselves in the process. Using an iterative inductive approach, a conceptual framework was developed in which specific (Tier 1) behaviors were placed within broader (Tier 2) categories, and these lower classification levels were, in turn, interpreted within a conceptual space defined by the (Tier 3) dimensions of task, relationship, and self. This framework was then elaborated and refined by reference to the psychology and marketing literature, a set of 157 audio‐recorded service interactions, and an expert panel study. The paper includes comparisons between the framework and those previously proposed, propositions regarding service encounter processes and outcomes, and implications for future research and practice.
Very high cycle fatigue of VDSiCr spring steel under torsional and axial loading

Published: April 2013

AbstractVery high cycle fatigue (VHCF) properties of VDSiCr spring steel are investigated with ultrasonic equipment under fully reversed cyclic torsion loading and under cyclic axial loading at load ratios R = –1, R = 0.1 and R = 0.5. Shot‐peened specimens with surface finish similar to valve springs in combustion engines are tested until limiting lifetimes of 1010 cycles. Under cyclic torsion loading, specimens either fail below 106 cycles with crack initiation at the surface or they do not fail. Under cyclic axial loading, failures above 109 cycles were found for all load ratios with crack initiation at the surface or at internal inclusions. Ratio of mean endurance limit (50% failure probability at 1010 cycles) under fully reversed cyclic torsion and cyclic tension‐compression loading is 0.86. Cyclic torsion loading slightly below the endurance limit leads to cyclic softening first followed by cyclic hardening whereas cyclic stability is found for tension‐compression loading. Cyclic torsion reduces surface compression stresses whereas they are hardly affected by cyclic tension‐compression loading. Mean endurance limit at 1010 cycles for R = 0.1 is 61% of the endurance stress amplitude at load ratio R = –1, and for R = 0.5 it is 44% of the tension‐compression endurance limit. Endurance limits for cyclic torsion and cyclic tension‐compression loading are comparable, if effective stress amplitude is used that considers cyclic normal stresses and residual compression stresses at the surface.

Published: April 2013

AbstractThe elastic properties of a material are an important factor for the designing and dimensioning of structural and functional components with respect to the dimensional stability, the spring‐back behavior or the fatigue properties. The present work is focused on the impact of the elastic anisotropy on a rolling contact loading of a severely deformed ferritic steel. Linear profiles produced by the newly developed forming process called linear flow splitting are considered to be well suitable as linear guides, due to their reduced surface roughness and highly increased surface hardness. Orientation data obtained by EBSD measurements are used for the calculation of the elastic tensors of the severely deformed parts applying the geometric mean in addition to the classical Voigt and Reuss approaches. The produced profiles exhibit a strong elastic anisotropy in the plane parallel to the desired rolling contact surface showing a strong gradient in forming rate. The evaluation of the stresses in the rolling contact area of the formed microstructure is estimated by the implementation of the determined compliance tensors into a finite element rolling‐contact model. In comparison to results with a homogeneous and isotropic material model the results are analyzed with respect to the rolling contact loading based on the von Mises failure criterion.

ScopeFlavanol‐rich foods are known to exert beneficial effects on cardiovascular health. The biological effects depend on bioavailability of flavanols which may be influenced by food matrix and dose ingested. We compared the bioavailability and dose‐response of epicatechin from whole apple and an epicatechin‐rich extract, and the effects on plasma and urinary nitric oxide (NO) metabolites.Methods and resultsIn a randomized, placebo‐controlled, crossover trial, subjects consumed drinks containing 70 and 140 mg epicatechin from an apple extract and an apple puree containing 70 mg epicatechin. Blood and urine samples were collected for 24 h post ingestion. Maximum plasma concentration, AUC(0–24 h), absorption and urinary excretion were all significantly higher after ingestion of both epicatechin drinks compared with apple puree (p < 0.05). Time to maximum plasma concentration was significantly later for the puree compared with the drinks (p < 0.01). Epicatechin bioavailability was >2‐fold higher after ingestion of the 140 mg epicatechin drink compared to the 70 mg epicatechin drink (p < 0.05). Excretion of NO metabolites was higher for all test products compared with placebo, which was significant for the high dose drink (p = 0.016).ConclusionsOral bioavailability of apple epicatechin increases at higher doses, is reduced by whole apple matrix and has the potential to increase NO bioavailability.

SUMMARYBora is the binding partner of Aurora A, which is required for its activation and phosphorylation of Polo like kinase 1 (Plk1), and is involved in the spindle assembly and progress of the cell cycle during mitosis. In this study, we examined the expression, localization, and function of Bora during mouse oocyte meiosis. The expression level of Bora was increased during oocyte meiotic maturation, with an elevated level at metaphase. Immunofluorescence analysis showed that Bora was concentrated as a dot shortly after germinal vesicle breakdown (GVBD), associating first with the surrounding chromosomes and then with the spindle throughout oocyte meiotic maturation. Further experiments confirmed that Bora co‐localized with α‐tubulin at prometaphase/metaphase, but dissociated from α‐tubulin at anaphase/telophase. In metaphase‐II‐arrested oocytes, Bora was evenly distributed in the cytoplasm after treatment with a microtubule‐depolymerizing agent, or recruited to the spindle after treatment with a microtubule‐polymerizing agent, indicating that Bora was physically connected to the meiotic spindle and α‐tubulin at metaphase. Furthermore, inhibition or depletion of Bora by either anti‐Bora antibody or Bora siRNA microinjection significantly reduced the rates of GVBD and inhibited first polar body extrusion; caused morphologically defective spindles and misaligned chromosomes; arrested maturing oocytes at prometaphase/metaphase‐I stage, or left oocytes and their first polar bodies with severely misaligned chromosomes and defective spindles; and/or caused the disappearance of Aurora A and Plk1 at the spindle. These results indicated that Bora acts as a critical regulator of Aurora A and Plk1, and is involved in microtubule organization during oocyte meiosis. Mol. Reprod.

Effective transfer properties of partially saturated geomaterials with interfaces using the immersed interface method
Authors: Do Duc Phi , Hoxha Dashnor 
Published: April 2013

SUMMARYThe present work aims at introducing an efficient numerical approach based on the immersed interface method to estimate the effective thermal conductivity and permeability of geomaterials as porous media with either perfect or debonded interfaces. The first part deals with the problem of the overall thermal properties of a medium containing perfectly bonded inclusions. The evolution of the homogenized properties with respect to the properties of individual constituents, the volume fraction, the spatial distribution, and the shape of inclusions is highlighted. The second part of the paper is devoted to the case of imperfectly bonded inclusions. An extension of the immersed interface method in this context makes it possible to study other aspects that have an influence on the effective properties such as the interfacial resistance and the size of inclusions. The application of the proposed numerical tool to some porous rocks in partially saturated condition shows good agreement with the available experimental results and demonstrates the performance and the flexibility of the developed procedure.Copyright © 2013 John Wiley & Sons, Ltd.
Fenced In: Intimacy and Mobility in Highlands Papua New Guinea
Authors: Maclean Neil 
Published: April 2013

AbstractThis paper is organised around the analysis of an ‘event’; a truck trip from Kwima, a Maring speaking settlement in the Western Highlands of Papua New Guinea, to Banz in the Wahgi Valley and an evening spent on the road. The event forms a standpoint from which to assess the impact of the decline of civic space, and faltering legacy of colonial governmentality, in the Jimi since 1980. I describe the emergence of new forms of mobility based around the nexus between local forms of business and trucks. In particular I focus on new and anxious forms of masculine inside relationships, understood as a transformation of a habitus of intimacy, round which such mobility is built. I argue that this transformation should be understood in terms of the dialectical relationship between business as an expansive profit oriented project on the one hand, and its anchoring in clan defined space on the other. At the same time the event provides a vantage point to reflect on the nature of long‐term fieldwork, the methodological significance of the subjectivity of the ethnographer, and the nature of ethnographic error.
Black hole quantum mechanics in the presence of species
Authors: Dvali G. , Gomez C. , Lüst D. 
Published: April 2013

AbstractRecently within the context of a microscopic quantum theory, the Black Hole's Quantum N‐Portrait, it was shown that continuous global symmetries are compatible with quantum black hole physics. In the present paper we revise within the same framework the semi‐classical black hole bound on the number of particle species Nspecies. We show that unlike the bound on global charge, the bound on species survives in the quantum picture and gives rise to a new fundamental length‐scale, Lspecies = √(Nspecies) LP, beyond which the resolution of species identities is impossible. This finding nullifies the so‐called species problem. This scale sets the size of the lightest quantum black hole in the theory, Planckion. A crucial difference between the gravitational and non‐gravitational species emerges. For gravitational species, the lightest black holes are exactly at the scale of perturbative unitarity violation, which is a strong indication for self‐UV‐completion of gravity. However, non‐gravitational species create a gap between the perturbative unitarity scale and the lightest black holes, which must be filled by some unitarity‐restoring physics. Thus, self‐UV‐completion of gravity implies that the number of non‐gravitational species must not exceed the gravitational ones.
Ranking multiple docking solutions based on the conservation of inter‐residue contacts

Published: April 2013

ABSTRACTMolecular docking is the method of choice for investigating the molecular basis of recognition in a large number of functional protein complexes. However, correctly scoring the obtained docking solutions (decoys) to rank native‐like (NL) conformations in the top positions is still an open problem. Herein we present CONSRANK, a simple and effective tool to rank multiple docking solutions, which relies on the conservation of inter‐residue contacts in the analyzed decoys ensemble. First it calculates a conservation rate for each inter‐residue contact, then it ranks decoys according to their ability to match the more frequently observed contacts. We applied CONSRANK to 102 targets from three different benchmarks, RosettaDock, DOCKGROUND, and Critical Assessment of PRedicted Interactions (CAPRI). The method performs consistently well, both in terms of NL solutions ranked in the top positions and of values of the area under the receiver operating characteristic curve. Its ideal application is to solutions coming from different docking programs and procedures, as in the case of CAPRI targets. For all the analyzed CAPRI targets where a comparison is feasible, CONSRANK outperforms the CAPRI scorers. The fraction of NL solutions in the top ten positions in the RosettaDock, DOCKGROUND, and CAPRI benchmarks is enriched on average by a factor of 3.0, 1.9, and 9.9, respectively. Interestingly, CONSRANK is also able to specifically single out the high/medium quality (HMQ) solutions from the docking decoys ensemble: it ranks 46.2 and 70.8% of the total HMQ solutions available for the RosettaDock and CAPRI targets, respectively, within the top 20 positions.

Published: April 2013

AbstractBackgroundAdvanced flexible endoscopes and instruments with multiple degrees of freedom enable physicians to perform challenging procedures such as the removal of large sections of mucosal tissue. However, these advanced endoscopes are difficult to control and require several physicians to cooperate.MethodsIn this article, we present a robotic system that allows the physician to control an instrument in an intuitive way, using a haptic device. Performance with the robotic and conventional control methods were compared in a human subjects experiment. Subjects used both methods to tap a series of targets. They performed four trials while looking at the endoscopic monitor, and two trials while looking at the instrument directly.ResultsSubjects were significantly faster using the robotic method, 54 s vs 164 s. Their performance in the second trial was significantly improved with respect to the first trial.ConclusionsThis study provides evidence that the robotic control method can be implemented to improve the performance of physicians using advanced flexible endoscopes.

An extended probabilistic model building genetic network programming using both of good and bad individuals
Authors: Li Xianneng , Mabu Shingo , Hirasawa Kotaro 
Published: April 2013

AbstractClassical estimation of distribution algorithms (EDAs) generally use truncation selection to estimate the distribution of the good individuals while ignoring the bad ones. However, various researches in evolutionary algorithms (EAs) have reported that the bad individuals may affect and help solving the problem. This paper proposes a new method to use the bad individuals by studying the substructures rather than the entire individual structures to solve reinforcement learning (RL) problems, which generally factorize their entire solutions to the sequences of state–action pairs. This work was studied in a recent graph‐based EDA named probabilistic model building genetic network programming (PMBGNP), which could solve RL problems successfully, to propose an extended PMBGNP. The effectiveness of this work is verified in an RL problem, namely robot control. Compared to other related work, results show that the proposed method can significantly speed up the evolution efficiency. © 2013 Institute of Electrical Engineers of Japan.

AbstractObjectiveTo estimate the incidence of Bartholin duct cysts and abscesses in the Republic of Korea during 2009.MethodsA national patient sample (n = 599 186) was obtained from Korean Health Insurance Review and Assessment Service data and analyzed to estimate the incidence of Bartholin duct cysts and abscesses among Korean women in 2009.ResultsThere were 587 Bartholin duct cysts and 757 Bartholin duct abscesses during 2009. The total incidence of Bartholin duct cysts and abscesses was 0.55 per 1000 person‐years and 0.95 per 1000 person‐years, respectively. In women aged 35–50 years, the incidence was 1.21 per 1000 person‐years and 1.87 per 1000 person‐years, respectively. In multivariate logistic regression analysis, the incidence of Bartholin duct cysts and abscesses was associated with age (P < 0.01), but not with season or socioeconomic status, among women aged 15–50 years. The main operation performed was marsupialization (45.2%) for Bartholin duct cysts and incision (71.5%) for Bartholin duct abscesses.ConclusionThe incidence of Bartholin duct cysts and abscesses increased with age until menopause, decreasing thereafter.

AbstractObjectiveTo determine whether use of uterine balloon tamponade (UBT) for management of uncontrolled postpartum hemorrhage (PPH) by community‐based providers in a resource‐limited setting could be feasible, effective, and safe.MethodsIn rural South Sudan, community providers were trained and equipped with a simple UBT device consisting of a catheter, condom, and syringe. Snowball sampling identified cases of UBT use since training. Semi‐structured interviews were conducted among community providers, referral facility providers, patients, and patient family members. Interview transcripts were analyzed using qualitative methods.ResultsThirteen cases were identified and 24 interviews related to community‐based UBT use were conducted. Qualitative analysis revealed several major themes. Community providers applied UBT in appropriate clinical situations. UBT was effective for controlling PPH, even among severely ill patients. Referral was difficult and lengthy owing to the austere setting, but simple UBT appeared to mitigate these challenges. Communities had some initial fears, yet ultimately embraced UBT. Equipment and supplies were largely maintained. There was universal satisfaction with UBT among patients, family members, and providers. One death occurred among the 13 cases, although it was probably not attributable to PPH.ConclusionTraining and UBT device provision are simple, affordable, and effective for managing uncontrolled PPH in a resource‐limited setting.

AbstractThis study investigates the importance of contextual factors on the efficacy of ISO 9000 adoption. We explore the role of various contextual factors at the firm‐level (i.e., technology intensity, labor productivity, and labor intensity) and industry‐level (i.e., industry efficiency level, industry competitiveness, industry sales growth, and industry ISO 9000 adoption level) that potentially impact the efficacy of ISO 9000 adoption. We carry out a hierarchical linear modeling (HLM) analysis based on objective financial data from 438 U.S. manufacturing firms. The results show that firms with low technology intensity, low labor productivity and high labor intensity reap more benefit from ISO 9000 adoption. Firms in industries with low efficiency levels, high competition, high sales growth and low ISO 9000 adoption levels also obtain more benefit from the adoption. Our research provides supporting evidence for the context‐dependent proposition of ISO 9000 adoption. Given the significant costs and resources involved, it is crucial for operations managers to assess to what extent ISO 9000 might benefit their performance before embarking on the implementation process.

Published: April 2013

Einleitung
Gesundheits- und Bewegungsförderung sind auch in stationären Pflegeeinrichtungen zu einem Thema geworden. In der Praxis führen jedoch Informationsdefizite und Umsetzungsprobleme dazu, dass besonders körperlich und kognitiv stark beeinträchtigte Nutzer nur eingeschränkt Zugang zu bewegungsförderlichen Interventionen haben. Zur Verbesserung der Situation bedarf es sowohl einer Neu- und Weiterentwicklung der Angebote, als auch der Verbesserung der Information über existierende Konzepte.
