Published: January 2015

AbstractWe have engineered the electronic structure at the interface between Cu2O and ZnO nanorods (NRs) array, through adjusting the carrier concentration of Cu2O. The electrodeposition of Cu2O at pH 11 acquired the highest carrier concentration, resulting in the largest interfacial electric field between Cu2O and ZnO, which finally led to the highest separation efficiency of photogenerated charge carriers. The optimized Cu2O/ZnO NRs array p-n heterostructures exhibited enhanced PEC performance, such as elevated photocurrent and photoconversion efficiency, as well as excellent sensing performance for the sensitive detection of glutathione (GSH) in PBS buffer even at applied bias of 0 V which made the device self-powered. Besides, the favorable selectivity, high reproducibility and extremely wide detection range, make such heterostructure a promising candidate for PEC biosensing applications, probably for the extended field of PEC water splitting or other solar photovoltaic beacons.

Published: January 2015

AbstractWe demonstrate an 80-μm-thick film (which is around 15% of the thickness of the human epidermis), which is a highly sensitive hybrid functional gauge sensor and was fabricated from poly(vinylidene fluoride) (PVDF) and ZnO nanostructures with graphene electrodes. Using this film, we were able to simultaneously measure pressure and temperature in real time. The pressure was monitored from the change in the electrical resistance via the piezoresistance of the material and the temperature was inferred based on the recovery time of the signal. Our thin film system enabled us to detect changes in pressure as small as 10 Pa which is pressure detection limit was 103-fold lower than the minimum level required for artificial skin and to detect temperatures in the range 20–120°C.

Published: January 2015

AbstractTopological insulators (TIs) are enticing prospects for the future of spintronics due to their large spin-orbit coupling and dissipationless, counter-propagating conduction channels in the surface state. However, a means to interact with and exploit the topological surface state remains elusive. Here, we report a study of spin pumping at the TI-ferromagnet interface, investigating spin transfer dynamics in a spin-valve like structure using element specific time-resolved x-ray magnetic circular dichroism and ferromagnetic resonance. Gilbert damping increases approximately linearly with increasing TI thickness, indicating efficient behaviour as a spin sink. However, layer-resolved measurements suggest that a dynamic coupling is limited. These results shed new light on the spin dynamics of this novel material class and suggest great potential for TIs in spintronic devices, through their novel magnetodynamics that persist even up to room temperature.

Authors: Yun Daeyeon , Park Jungyong , Yun Kwang‐Seok 
Published: January 2015

Proposed is a helical piezoelectric structure for a highly stretchable energy harvester to be applied on the human body. The proposed device consists of two counter‐wound helical structures around a zcore structure made of an elastic fabric string. The inner fabric helix is used to separate the outer piezoelectric helix from the core to obtain a highly stretchable device. When stretched by 60% of its initial length, the device generates a maximum output voltage and power of 140 Vp‐p and 0.6 mW, respectively, at an operation frequency of 4 Hz.
Low start‐up voltage dc–dc converter with negative voltage control for thermoelectric energy harvesting
Authors: Lei Pui‐Sun , Chang Robert Chen‐Hao , Chia Chu‐Hsiang , Lee Ming‐Shiun 
Published: January 2015

This Letter presents a low start‐up voltage dc–dc converter for low‐power thermoelectric systems which uses a native n‐type MOS transistor as the start‐up switch. The start‐up voltage of the proposed converter is 300 mV and the converter does not need batteries to start up. The negative voltage control is proposed to reduce the leakage current caused by native n‐type transistor and increase the efficiency. The proposed converter was designed using standard 0.18 µm CMOS process with chip size of 0.388 mm2. The peak efficiency is 63% at load current of 1.5 mA. The proposed converter provides output voltage >1 V at maximum load current of 3.2 mA.
Deep profiling of multitube flow cytometry data

Published: January 2015

Abstract
Motivation: Deep profiling the phenotypic landscape of tissues using high-throughput flow cytometry (FCM) can provide important new insights into the interplay of cells in both healthy and diseased tissue. But often, especially in clinical settings, the cytometer cannot measure all the desired markers in a single aliquot. In these cases, tissue is separated into independently analysed samples, leaving a need to electronically recombine these to increase dimensionality. Nearest-neighbour (NN) based imputation fulfils this need but can produce artificial subpopulations. Clustering-based NNs can reduce these, but requires prior domain knowledge to be able to parameterize the clustering, so is unsuited to discovery settings.
Results: We present flowBin, a parameterization-free method for combining multitube FCM data into a higher-dimensional form suitable for deep profiling and discovery. FlowBin allocates cells to bins defined by the common markers across tubes in a multitube experiment, then computes aggregate expression for each bin within each tube, to create a matrix of expression of all markers assayed in each tube. We show, using simulated multitube data, that flowType analysis of flowBin output reproduces the results of that same analysis on the original data for cell types of &gt;10% abundance. We used flowBin in conjunction with classifiers to distinguish normal from cancerous cells. We used flowBin together with flowType and RchyOptimyx to profile the immunophenotypic landscape of NPM1-mutated acute myeloid leukemia, and present a series of novel cell types associated with that mutation.

Published: January 2015

Abstract
Summary: Accurate prediction of amyloid-forming amino acid sequences remains an important challenge. We here present an online database that provides open access to the largest set of experimentally characterized amyloid forming hexapeptides. To this end, we expanded our previous set of 280 hexapeptides used to develop the Waltz algorithm with 89 peptides from literature review and by systematic experimental characterisation of the aggregation of 720 hexapeptides by transmission electron microscopy, dye binding and Fourier transform infrared spectroscopy. This brings the total number of experimentally characterized hexapeptides in the WALTZ-DB database to 1089, of which 244 are annotated as positive for amyloid formation.
Availability and implementation: The WALTZ-DB database is freely available without any registration requirement at http://waltzdb.switchlab.org.

Abstract

Background
Integrated vector management strategies depend on local eco-bio-social conditions, community participation, political will and inter-sectorial partnership. Previously identified risk factors for persistent Triatoma dimidiata infestation include the presence of rodents and chickens, tiled roofs, dirt floors, partial wall plastering and dog density.

Methods
A community-based intervention was developed and implemented based on cyclical stakeholder and situational analyses. Intervention implementation and evaluation combined participatory action research and cluster randomized pre-test post-test experimental designs. The intervention included modified insecticide application, education regarding Chagas disease and risk factors, and participatory rodent control.

Results
At final evaluation there was no significant difference in post-test triatomine infestation between intervention and control, keeping pre-test rodent and triatomine infestations constant. Knowledge levels regarding Chagas disease and prevention practices including rodent control, chicken management and health service access increased significantly only in intervention communities. The odds of nymph infection and rat infestation were 8.3 and 1.9-fold higher in control compared to intervention communities, respectively.

Conclusion
Vector control measures without reservoir control are insufficient to reduce transmission risk in areas with persistent triatomine infestation. This integrated vector management program can complement house improvement initiatives by prioritizing households with risk factors such as tiled roofs. Requirement for active participation and multi-sectorial coordination poses implementation challenges.
Staff views of a music therapy group for people with intellectual disabilities and dementia: a pilot study
Authors: Bevins Shelley , Dawes Simone , Kenshole Athena , Gaussen Kathryn 
Published: January 2015

Purpose
– Despite the longstanding use of music therapy with people with intellectual disabilities and the growing evidence base for using music therapy as a tool to aid behavioural and psychological symptoms of dementia in the general population, there is little work published which details the use of music therapy groups for people with intellectual disabilities who have a diagnosis of dementia. The purpose of this paper is to report a qualitative evaluation of staff views of a music therapy group for people with intellectual disabilities and dementia.

Design/methodology/approach
– Carers of service users attending the group were interviewed either individually or through a focus group in order to ascertain their views about the music therapy group. The interview transcripts were then analysed using thematic analysis.

Findings
– Two core themes and eight sub themes emerged from the data. These themes show that the group was felt to be pleasurable and enjoyable for the service users and that some tangible benefits of attending the group were observed by staff members. Notwithstanding the positive feedback, the results also suggested that more work is needed to inform carers of the goals and purpose of such groups. Further psycho-education for carers is suggested as a strategy to support future groups to run successfully.

Originality/value
– There is little published research into the use of music therapy for people with intellectual disabilities who also have dementia. The current paper provides a starting point for future work in the area and further recommendations for future practice and research are considered.
Who cooks from scratch and how do they prepare food?
Authors: Worsley Tony , Wang Wei Chun , Wijeratne Pradeep , Ismail Sinem , Ridley Stacey 
Published: January 2015

Purpose
– There is increasing interest in the domestic preparation of food and with the postulated health benefits of “cooking from scratch”. The purpose of this paper is to examine the demographic and food preparation associations of this term in order to examine its operational value.

Design/methodology/approach
– A national online survey was conducted during 2012 in Australia among 1,023 domestic food providers, half of whom were men. Questions were asked about cooking from scratch, demographic characteristics, food preparation practices and interest in learning about cooking.

Findings
– Three quarters of the sample reported they often or always “cooked from scratch” (CFS). More women than men always CFS; fewer 18-29 year olds did so often or always but more of the over 50s always did so; fewer single people CFS than cohabiting people. No statistically significant ethnic, educational background or household income differences were found. High levels of cooking from scratch were associated with interest in learning more about cooking, greater use of most cooking techniques (except microwaves), meat and legume preparation techniques, and the use of broader ranges of herbs, spice, liquids/ sauces, other ingredients and cooking utensils.

Research limitations/implications
– In future work a numerical description of the frequency of cooking from scratch should be considered along with a wider range of response options. The data were derived from an online panel from which men were oversampled. Caution is required in comparisons between men and women respondents. The cross-sectional nature of the sample prevents any causal attributions from being drawn from the observed relationships. Further replication of the findings, especially the lack of association with educational background should be conducted.

Originality/value
– This is the first study to examine the associations of demographic characteristics and cooking practices with cooking from scratch. The findings suggest that cooking from scratch is common among Australian family food providers and signifies interest in learning about cooking and involvement in a wide range of cooking techniques.
Teaching outbreak investigation to undergraduate food technologists
Authors: Karlsen Hanne , Mehli Lisbeth , Wahl Erik , Staberg Ragnhild Lyngved 
Published: January 2015

Purpose– Investigations of food-borne outbreaks are complex and require multidisciplinary collaboration. The purpose of this paper is to help food technologists face this challenge and be competent members of a multidisciplinary team, a study module on the investigation of a “real-life” food-borne outbreak was developed.Design/methodology/approach– The module design was based on the principles of inquiry-based learning with the purpose to motivate and activate students with challenging assignments. The didactic impact of the module was evaluated as a qualitative case study with questionnaires, reflection assignments and interviews of students and lecturers.Findings– A teaching module developed by an external professional taking part in the academic environment provides a learning environment well adapted to the curriculum, as well as bringing first-hand realism and enthusiasm into the classroom. The external lecturer’s dedication to the subject was appreciated by the students. A majority of the students believed that the outbreak investigation simulation play gave a better understanding of how food-borne outbreaks are investigated. A majority of the students 68 per cent (2011) and 82 per cent (2012) believed that what they learned in this module would be useful in a future work situation.Research limitations/implications– There are some limitations to the study, the most important one being the small sample size, and as the classes rarely exceeds 30 students, the use of a control group was not logistically feasible.Originality/value– Teaching food technologists to become knowledgeable professionals in this field will constitute a valuable contribution to the multidisciplinary food-borne outbreak investigation team. In turn, this may increase confidence among the general public in the food industry.

Authors: Assiouras Ioannis , Liapati Georgia , Kouletsis Georgios , Koniordos Michalis 
Published: January 2015

Purpose– The purpose of this paper is to investigate the impact of brand authenticity on brand attachment and subsequently on consumer behaviour related to food brands.Design/methodology/approach– Results are derived from primary data collected from a consumer sample in Greece. Respondents rate their brand authenticity and brand attachment for two well established authentic Greek brands in the food industry.Findings– The study confirms that brand authenticity predicts the brand attachment, while brand attachment influences consumers purchase intentions, willingness to pay more and promote the brand.Practical implications– The benefits of brand authenticity should not be ignored and should be protected by the brand managers of food brands because it can be the one of the competitive advantages that can be leveraged in the competitive food industry sector.Originality/value– It provides the required empirical support for the impact of brand authenticity on brand attachment and behavioural intentions in the food industry.
The region-of-origin (ROO) effect on purchasing preferences
Authors: Chamorro Antonio , Rubio Sergio , Miranda F. Javier 
Published: January 2015

Purpose
– The purpose of this paper is to analyse the “region-of-origin” effect in the purchase of cava, a sparkling wine. Cava is a multiregional designation of origin: although it is a product typical of a particular Spanish region (Catalonia), it is also produced in other regions in Spain.

Design/methodology/approach
– The technique of conjoint analysis is used to identify the structure of the preferences of cava consumers, and to evaluate how that structure is affected by the inclusion of a message that highlights the regional origin of the product. A survey was conducted among 473 wine buyers in the region of Extremadura (Spain).

Findings
– The main findings show that the “region-of-origin” effect is significant for the regional buyer of this type of wine, and that the sales of regional brands of cava would be greater if their regional origin were emphasized by indicating the location of the producer in a prominent place on the label. Moreover, three segments of purchasers differentiated by their preference structure are identified.

Originality/value
– The novelty of the study lies in the fact that this PDO is a multiregional designation of origin, and that the technique used, conjoint analysis, is applied not only to determine the buyer’s preference structure, but also to evaluate how that structure is affected when the regional origin of the product is highlighted in the message to the purchaser. This study is of value to academic researchers, wineries managers, and regional governments as it highlights important aspects to design marketing strategies and trade policies.
Global brands or local heroes?: evidence from the Spanish beer market
Authors: Calvo Porral Cristina , Levy-Mangin Jean-Pierre 
Published: January 2015

Purpose
– The purpose of this paper is to investigate how consumers perceive and evaluate local and global brands – in a developed mature European market.

Design/methodology/approach
– For this purpose, four dimensions and two consequences of brand equity are evaluated, based on consumers’ standpoint. Structural equation modeling is carried out in order to analyze results obtained.

Findings
– The findings suggest that brand loyalty, brand image and perceived quality exert the higher influence on consumers’ brand value; while there are relevant differences in consumer’s assessment toward local and global brands.

Originality/value
– This study provides local and global brand marketers with further specific knowledge on how to market and enhance their brands’ value in a globalized increasingly competitive world.
The influence of celebrity chefs on a student population
Authors: Lane Samantha Rosemary , Fisher Stephanie Margaret 
Published: January 2015

Purpose
– The purpose of this paper is to investigate the exposure of a student population to celebrity chef television programmes, to assess the influence these figures have, and how they are perceived.

Design/methodology/approach
– A survey was conducted through an online questionnaire distributed at Bath Spa University. The approach included asking respondents why they watched programmes featuring celebrity chefs; to select a named celebrity chef whom they thought had most influenced their food habits, and to name particular chefs relating to campaign descriptions.

Findings
– A significant proportion of the study group watched television programmes fronted by celebrity chefs (84 per cent); the main reason for watching was for entertainment. Overall, reported influence was insignificant, though Jamie Oliver was selected as the chef with most influence on the respondent’s food habits. Jamie Oliver’s campaign to improve school dinners was also the most recognised, and celebrity chefs were generally viewed positively.

Research limitations/implications
– The study population was quite specific in its gender, age and ethnicity, and therefore might not be representative of wider society. Further work could consider gender differences in chef influence, as well as different forms of exposure.

Originality/value
– Despite their ubiquity, academic research into the role of the celebrity chef in modern society is limited, where very few studies have assessed the influence of named chefs or the public perception of these figures. This paper gives an insight into this under-researched field.
Effect of food service-brand equity on consumer-perceived food value, physical risk, and brand preference
Authors: Wang Edward S.-T. 
Published: January 2015

Purpose
– Although food product value and food safety is widely acknowledged as a critical concern by consumers, little empirical evidence exists regarding how food product value is created and how product risk decreases as a result of service-brand equity. The purpose of this paper is to explore whether food service-brand equity (i.e. brand awareness and brand image) affects consumer-perceived food value, food physical risk, and brand preference.

Design/methodology/approach
– In this study, data were collected from steakhouse consumers using a convenience sample (n=386). Structural equation modelling was used to analyse the survey data.

Findings
– The results reveal that service-brand awareness and brand image produce considerably dissimilar effects on consumer-perceived food value and risk. Brand awareness positively affects consumer-perceived food value but does not influence perceived physical risk. By contrast, brand image negatively influences perceived physical risk and positively affects brand preference, but it does not add perceived value to the food product.

Originality/value
– This study is the first to address these concerns, which are essential for understanding the role of service-brand equity in developing food-risk and value perceptions, and brand preference.
