Published: February 2015

AbstractPolypyrrole (PPy)/cellulose (PPCL) composite papers were fabricated by vapor phase polymerization. Importantly, the vapor-phase deposition of PPy onto cellulose was assisted by employing different co-vapors namely methanol, ethanol, benzene, water, toluene and hexane, in addition to pyrrole. The resulting PPCL papers possessed high mechanical flexibility, large surface-to-volume ratio and good redox properties. Their main properties were highly influenced by the nature of the co-vaporized solvent. The morphology and oxidation level of deposited PPy were tuned by employing co-vapors during the polymerization, which in turn led to change in the electrochemical properties of the PPCL papers. When methanol and ethanol were used as co-vapors, the conductivities of PPCL papers were found to have improved five times, which was likely due to the enhanced orientation of PPy chain by the polar co-vapors with high dipole moment. The specific capacitance of PPCL papers obtained using benzene, toluene, water and hexane co-vapors was higher than those of the others, which is attributed to the enlarged effective surface area of the electrode material. The results indicate that the judicious choice and combination of co-vapors in vapor-deposition polymerization (VDP) offers the possibility of tuning the morphological, electrical and electrochemical properties of deposited conducting polymers.
Language Exposure in Bilingual Toddlers: Performance on Nonword Repetition and Lexical Tasks
Authors: Brandeker Myrto , Thordardottir Elin 
Published: February 2015

Purpose
The amount of language exposure is correlated with bilingual lexical development, but findings are mixed on how exposure relates to nonword repetition (NWR), a complex skill involving both short-term processing and long-term vocabulary knowledge. We extend previous work to a younger age group by investigating the role of exposure on NWR versus vocabulary, along with the effect of item construction and scoring.

Method
Sixty typically developing children (ages 2;5–3;6[years;months]) were assessed for NWR and receptive and expressive vocabulary. Participants ranged in amount of previous exposure to English and French from 0% to 100% and were tested in both languages if able to participate, even with very limited exposure (28 completed testing in both languages, 11 completed testing in English only, 21 completed testing in French only).

Results
Correlational analyses showed moderate to strong associations between the amount of exposure and vocabulary in that language, whereas the relationship of exposure with NWR was weak or nonsignificant, depending on scoring method. NWR correlated with vocabulary in English only. Performance on NWR was affected by nonword length but unaffected by wordlikeness.

Conclusions
NWR and vocabulary were differently related to language exposure. The underlying mechanisms of NWR at this age appeared mainly reliant on short-term processes, in contrast to long-term vocabulary knowledge.
Intentional and Reactive Inhibition During Spoken-Word Stroop Task Performance in People With Aphasia
Authors: Pompon Rebecca Hunting , McNeil Malcolm R. , Spencer Kristie A. , Kendall Diane L. 
Published: February 2015

Purpose
The integrity of selective attention in people with aphasia (PWA) is currently unknown. Selective attention is essential for everyday communication, and inhibition is an important part of selective attention. This study explored components of inhibition—both intentional and reactive inhibition—during spoken-word production in PWA and in controls who were neurologically healthy (HC). Intentional inhibition is the ability to suppress a response to interference, and reactive inhibition is the delayed reactivation of a previously suppressed item.

Method
Nineteen PWA and 20 age- and education-matched HC participated in a Stroop spoken-word production task. This task allowed the examination of intentional and reactive inhibition by evoking and comparing interference, facilitation, and negative priming effects in different contexts.

Results
Although both groups demonstrated intentional inhibition, PWA demonstrated significantly more interference effects. PWA demonstrated no significant facilitation effects. HC demonstrated significant reverse facilitation effects. Neither group showed significant evidence of reactive inhibition, though both groups showed similar individual variability.

Conclusions
These results underscore the challenge interference presents for PWA during spoken-word production, indicating diminished intentional inhibition. Although reactive inhibition was not different between PWA and HC, PWA showed difficulty integrating and adapting to contextual information during language tasks.

Authors: Kapsner-Smith Mara R. , Hunter Eric J. , Kirkham Kimberly , Cox Karin , Titze Ingo R. 
Published: February 2015

Purpose
Although there is a long history of use of semi-occluded vocal tract gestures in voice therapy, including phonation through thin tubes or straws, the efficacy of phonation through tubes has not been established. This study compares results from a therapy program on the basis of phonation through a flow-resistant tube (FRT) with Vocal Function Exercises (VFE), an established set of exercises that utilize oral semi-occlusions.

Method
Twenty subjects (16 women, 4 men) with dysphonia and/or vocal fatigue were randomly assigned to 1 of 4 treatment conditions: (a) immediate FRT therapy, (b) immediate VFE therapy, (c) delayed FRT therapy, or (d) delayed VFE therapy. Subjects receiving delayed therapy served as a no-treatment control group.

Results
Voice Handicap Index (Jacobson et al., 1997) scores showed significant improvement for both treatment groups relative to the no-treatment group. Comparison of the effect sizes suggests FRT therapy is noninferior to VFE in terms of reduction in Voice Handicap Index scores. Significant reductions in Roughness on the Consensus Auditory-Perceptual Evaluation of Voice (Kempster, Gerratt, Verdolini Abbott, Barkmeier-Kraemer, & Hillman, 2009) were found for the FRT subjects, with no other significant voice quality findings.

Conclusions
VFE and FRT therapy may improve voice quality of life in some individuals with dysphonia. FRT therapy was noninferior to VFE in improving voice quality of life in this study.

Published: February 2015

The mechanisms involved in the development of severe angioobliterative pulmonary arterial hypertension (PAH) are multicellular and complex. Many of the features of human severe PAH, including angioobliteration, lung perivascular inflammation, and right heart failure, are reproduced in the Sugen 5416/chronic hypoxia (SuHx) rat model. Here we address, at first glance, the confusing and paradoxical aspect of the model, namely, that treatment of rats with the antiangiogenic vascular endothelial growth factor (VEGF) receptor 1 and 2 kinase inhibitor, Sugen 5416, when combined with chronic hypoxia, causes angioproliferative pulmonary vascular disease. We postulated that signaling through the unblocked VEGF receptor VEGFR3 (or flt4) could account for some of the pulmonary arteriolar lumen–occluding cell growth. We also considered that Sugen 5416–induced VEGFR1 and VEGFR2 blockade could alter the expression pattern of VEGF isoform proteins. Indeed, in the lungs of SuHx rats we found increased expression of the ligand proteins VEGF‐C and VEGF‐D as well as enhanced expression of the VEGFR3 protein. In contrast, in the failing right ventricle of SuHx rats there was a profound decrease in the expression of VEGF‐B and VEGF‐D in addition to the previously described reduction in VEGF‐A expression. MAZ51, an inhibitor of VEGFR3 phosphorylation and VEGFR3 signaling, largely prevented the development of angioobliteration in the SuHx model; however, obliterated vessels did not reopen when animals with established PAH were treated with the VEGFR3 inhibitor. Part of the mechanism of vasoobliteration in the SuHx model occurs via VEGFR3. VEGFR1/VEGFR2 inhibition can be initially antiangiogenic by inducing lung vessel endothelial cell apoptosis; however, it can be subsequently angiogenic via VEGF‐C and VEGF‐D signaling through VEGFR3.
MESMER: minimal ensemble solutions to multiple experimental restraints
Authors: Ihms Elihu C. , Foster Mark P. 
Published: February 2015

Abstract
Motivation: Macromolecular structures and interactions are intrinsically heterogeneous, temporally adopting a range of configurations that can confound the analysis of data from bulk experiments. To obtain quantitative insights into heterogeneous systems, an ensemble-based approach can be employed, in which predicted data computed from a collection of models is compared to the observed experimental results. By simultaneously fitting orthogonal structural data (e.g. small-angle X-ray scattering, nuclear magnetic resonance residual dipolar couplings, dipolar electron-electron resonance spectra), the range and population of accessible macromolecule structures can be probed.
Results: We have developed MESMER, software that enables the user to identify ensembles that can recapitulate experimental data by refining thousands of component collections selected from an input pool of potential structures. The MESMER suite includes a powerful graphical user interface (GUI) to streamline usage of the command-line tools, calculate data from structure libraries and perform analyses of conformational and structural heterogeneity. To allow for incorporation of other data types, modular Python plugins enable users to compute and fit data from nearly any type of quantitative experimental data.
Results: Conformational heterogeneity in three macromolecular systems was analyzed with MESMER, demonstrating the utility of the streamlined, user-friendly software.

A numerical technique for linear elliptic partial differential equations in polygonal domains
Authors: Hashemzadeh P. , Fokas A. S. , Smitheman S. A. 
Published: February 2015

Integral representations for the solution of linear elliptic partial differential equations (PDEs) can be obtained using Green's theorem. However, these representations involve both the Dirichlet and the Neumann values on the boundary, and for a well-posed boundary-value problem (BVPs) one of these functions is unknown. A new transform method for solving BVPs for linear and integrable nonlinear PDEs usually referred to as the
unified transform
(
or the Fokas transform
) was introduced by the second author in the late Nineties. For linear elliptic PDEs, this method can be considered as the analogue of Green's function approach but now it is formulated in the complex Fourier plane instead of the physical plane. It employs two
global relations
also formulated in the Fourier plane which couple the Dirichlet and the Neumann boundary values. These relations can be used to characterize the unknown boundary values in terms of the given boundary data, yielding an elegant approach for determining the
Dirichlet to Neumann map
. The numerical implementation of the unified transform can be considered as the counterpart in the Fourier plane of the well-known boundary integral method which is formulated in the physical plane. For this implementation, one must choose (i) a suitable basis for expanding the unknown functions and (ii) an appropriate set of complex values, which we refer to as collocation points, at which to evaluate the global relations. Here, by employing a variety of examples we present simple guidelines of how the above choices can be made. Furthermore, we provide concrete rules for choosing the collocation points so that the condition number of the matrix of the associated linear system remains low.
Designations and consumer perceptions
Authors: Marano Marcolini Carla , Parras Rosa Manuel , Lopez-Zafra Esther 
Published: February 2015

Purpose
– The purpose of this paper is to analyze the labeling and denominations of olive oils and to examine to what extent these factors confuse consumers. Specifically, the authors analyze the extent to which the different denominations of olive oil prevent consumers from distinguishing among the types of olive oil. Furthermore, the authors analyze whether the current generic names of olive oil affect consumer perceptions regarding the product’s various qualities and characteristics.

Design/methodology/approach
– The authors performed an experiment with 128 participants divided into two groups (experimental n=64 and control n=64). In the pretest, participants completed a survey with 12 terms related to olive oil. The experimental group was then trained in the meaning of each term, after which the group returned to complete the same survey.

Findings
– The authors can confirm H1 and H2. Results show that there is no clear knowledge regarding some of these terms.

Social implications
– This study provides positive implications to both consumers, providing them a clear information, and producers and marketers, helping distinguish in the market olive oils of more quality.

Originality/value
– This paper is pioneer in the literature. The authors provide a number of proposals and amendments regarding olive oil names to improve the knowledge and clarity of olive oil with direct implications for agricultural policy.
Consumer perceptions of food quality in Malaysia
Authors: Chamhuri Norshamliza , Batt Peter J 
Published: February 2015

Purpose
– The purpose of this paper is to gain an understanding of the quality cues that consumers look for in purchasing fresh meat and fresh fruit and vegetables in Malaysia. Through a perceived quality model, this paper identifies the implicit, intrinsic, extrinsic and credence quality cues consumers’ use in their decision to purchase fresh meat and fresh fruit and vegetables.

Design/methodology/approach
– This study utilised the shopping mall intercept survey method. Data were collected from traditional markets and modern retail outlets in the Klang Valley region in Malaysia. A structured questionnaire was designed to measure consumer’s perceptions and experiences of food quality when purchasing fresh meat and fresh fruit and vegetables from retail outlets. In this study, univariate data analysis (descriptive analysis, one-way analysis of variance) and exploratory factor analysis were performed to analyse the data sets.

Findings
– Freshness (intrinsic cue), was the most frequently cited variable when respondents thought about the quality of both product categories. Other variables included price and cleanliness (extrinsic cues) and Halal (credence cue), which was associated with the quality of fresh meat. Quality was associated with freshness, food safety, nutrition and value. Exploratory factor analysis identified food safety (implicit cue) as the most important construct in the respondents’ evaluation of quality for both fresh meat and fresh fruit and vegetables.

Originality/value
– There is a paucity of research focusing on consumer’s perceptions and experiences of food quality in the purchase of fresh meat and fresh produce in Malaysia. The findings of this research may assist the Malaysian food industry by providing new insights into the consumers’ perceptions of food quality.
Consumer perceptions and attitudes of organic food products in Eastern China
Authors: Xie Biao , Wang Liyuan , Yang Hao , Wang Yanhua , Zhang Mingli 
Published: February 2015

Purpose
– In response to food scares related to high levels of agro-chemical residues sometimes found on foods, consumers in China increasingly demand for organic foods. As little is known on consumer perceptions and attitudes toward organic food products, the purpose of this paper is to gain insight into the purchase of organic food products by consumers and to explore the main factors driving this process.

Design/methodology/approach
– Mixed (quantitative and qualitative) market survey approaches were used to provide a potentially deeper insight into consumer’s perspective and could help get a better picture of the complex factors involved.

Findings
– The main trigger for purchasing organic food products is that consumers expect them to be healthier and safer. The respondents who have bought organic food products tend to have a higher education level and disposable incomes, be families with children and be older than those who have not bought them. The main barriers to increasing the market share of organic food products are the consumers’ lack of knowledge, the relatively high price premium and the lack of availability of organic food products. Informing consumers about unique characteristics of organic production methods, the decline in the prices of and increasing the availability of organic food products to its customers might be a promising strategy to develop the market for organic food products.

Originality/value
– This paper provides a unique insight into buying behavior and attitudes of organic consumers in China. The results of the research could provide information for the organic food industry to expand its market and improve its profitability and reliability.
Consumer motivation and willingness to pay for “safer” vegetables in Ghana
Authors: Yahaya Iddrisu , Yamoah Fred A. , Adams Faizal 
Published: February 2015

Purpose– The purpose of this paper is to assess consumer motivation and willingness to pay (WTP) for “safer” vegetables from the use of non-treatment options of wastewater use in urban/peri-urban vegetable production.Design/methodology/approach– As a theoretical basis, consumer theory of maximizing utility being an indicator of individual preference was examined through choice experiment (CE) method to measure the WTP for value of safety within the context of health reduced risk (pathogen reduction) of illness. WTP was tested empirically using survey data from 650 households in the two largest cities in Ghana (Accra and Kumasi) that are characterized by a number of well-established vegetable producers who use wastewater in their production and a large urban and peri-urban vegetable consumer market.Findings– Experience of vegetable borne diseases drives the need for safer vegetables and income and gender are key demographic factors influencing WTP. It was further found that consumers are willing to pay an average amount of GH¢ 4.7 ($2.40) per month for a technology change that would result in the production of “safer” vegetables.Research limitations/implications– Understanding WTP offers insight into consumer concerns, behaviour and their readiness to pay for safer vegetable options. However, a further consideration of the impact of the combinations of the various non-treatment options on pathogen reduction and the assessment of the financial viability of each option will collectively ensure an efficient and cost-effective implementation of the technologies.Practical implications– WTP insight gained has implications for vegetable production, marketing and public health policy. The understanding from the findings forms a solid basis to canvass for certification system for urban/peri urban vegetables. The information provided also helps to formulate effective public education on the safety of vegetables.Originality/value– Measuring WTP for safer vegetables by Ghanaian urban/peri-urban consumers is novel. The CE approach is robust and the findings can inform vegetable production and marketing decisions as well as public health policy formulation.

Published: February 2015

Purpose– The purpose of this paper is to uncover the effects of perceived transaction convenience (PTC) and perceived transaction speed (PTS) on unified theory of acceptance and use of technology (UTAUT) in the context of m-payment.Design/methodology/approach– A predictive analysis approach was used to examine the PTC and PTS using a two-stage partial least square (PLS) and neural network (NN) analyses.Findings– The findings reveal that only effort expectancy (EE) and facilitating conditions (FC) were discovered to significantly influence BI. More importantly, PTC was found to have positive significant relationship with EE and performance expectancy (PE). Moreover, PTS also supported the positive relationship with BI and EE.Practical implications– The findings of the study provided further insights to mobile payment service providers, online banking industry players, and all decision makers and stakeholders involved.Originality/value– Despite of many attempts devoted to understand m-payment adoption, the effects of PTC and PTS on m-payment are not well understood.
Fuzzy association rule mining for fashion product development
Authors: Lee Carmen Kar Hang , Tse Y.K. , Ho G.T.S. , Choy K.L. 
Published: February 2015

Purpose
– The emergence of the fast fashion trend has exerted a great pressure on fashion designers who are urged to consider customers’ preferences in their designs and develop new products in an efficient manner. The purpose of this paper is to develop a fuzzy association rule mining (FARM) approach for improving the efficiency and effectiveness of new product development (NPD) in fast fashion.

Design/methodology/approach
– The FARM identifies the hidden relationships between product styles and customer preferences. The knowledge discovered help the fashion industry design new products which are not only fashionable, but are also saleable in the market.

Findings
– To evaluate the proposed approach, a case study is conducted in a Hong Kong-based fashion company in which a real-set of data are tested to generate fuzzy association rules. The results reveal that the FARM approach can provide knowledge support to the fashion industry during NPD, shorten the NPD cycle time, and increase customer satisfaction.

Originality/value
– Compared with traditional association rule mining, the proposed FARM approach takes the fuzziness of data into consideration and the knowledge represented in the fuzzy rules is in a more human-understandable structure. It captures the voice of the customer into fashion product development and provides a specific solution to deal with the challenges brought by fast fashion. In addition, it helps increase the innovation and technological capability of the fashion industry.
