Can plate colour promote appetite and joy while dining? An investigative study in Chinese fine dining restaurants
Authors: Chen Yen-Cheng , Tsui Pei-ling , Lee Ching-Sung , Chen Guan-lin 
Published: June 2019

Purpose
This study used the colours of plates as atmospheric stimulus factors in the Mehrabian–Russell model of environmental influence, which served as the study’s basic background theory, to explore how plate colour affects consumer appetite preference and dining emotions in Chinese fine dining restaurants. The paper aims to discuss this issue.

Design/methodology/approach
The study used quantitative surveys and employed purposeful sampling and rolling snowball surveys of consumers in Chinese fine dining restaurants in Taipei; 581 effective surveys were collected from the test subjects. The research tools included a plate colour appetite preference scale and a dining emotion scale.

Findings
There were significant differences in age and gender in terms of appetite preference and plate colour. The plate colours with the highest appetite preference were gold, white and black. There were significant differences in plate colour appetite preference in terms of dining mood, with white and gold plates eliciting positive dining moods.

Originality/value
Most academic papers have focused on studying plates in Western dining, while very few studies have focused on the colour of Chinese dining plates. The greatest contribution and value of this study is its discovery of the colour combination of dining plates that can elicit appetite preferences and positive dining emotions among diners in Chinese fine dining restaurants. This information can be used to stimulate positive dining emotions among consumers and help restaurateurs improve the level of dining aesthetics.
The health-taste trade-off in consumer decision making for functional snacks
Authors: Papoutsi Georgia S. , Klonaris Stathis , Drichoutis Andreas 
Published: June 2019

Purpose
The purpose of this paper is twofold: first, to evaluate the claim that consumers are willing to compromise on taste in order to obtain the potential health benefits from functional snacks; and second, to investigate the effect of expectations for the snacks, blind tasting and product information on hedonic judgments and willingness to pay (WTP).

Design/methodology/approach
A sample of 160 subjects was recruited to participate in a lab experiment that combined hedonic evaluations and a series of non-hypothetical second-price Vickrey auctions, under blind or informed tasting conditions. Participants were also asked to complete a questionnaire about consumer preferences, purchasing habits and demographics.

Findings
Results indicate that tasting and information have economically and statistically significant effects on overall food assessment with respect to prior product expectations. Provision of information regarding functional food components shortly before consumption makes consumers less strict on their taste evaluation and increases their WTP. This indicates that consumers are willing to partly sacrifice the pleasure of taste in order to improve the healthfulness of their diet. When information is provided after taste, it only exerts influence with respect to the carob-based snack. Furthermore, blind tasting has a negative effect on liking, irrespective of the product being evaluated. Finally, the econometric results reveal that older respondents tend to bid higher for functional snacks.

Originality/value
This study contributes to the existing literature not only on the basis of the novelty of results but also on the methodological front, since it showcases the combined use of hedonic tests and auctions with real monetary incentives as a state of the art technique on eliciting consumers’ overall assessment for functional snacks. It also highlights important elements in the toolkit that marketers can use to influence products’ perceived health benefits, and thus consumption choices.

Published: June 2019

Purpose
This paper aims to examine the relationship of internal/external physical environments and emotional well-being and to explore the possible influence of such an association with guest satisfaction and retention considering the moderating role of price perception in the luxury resort hotel context.

Design/methodology/approach
A total of 603 responses were gathered from a field survey at luxury resort hotels. The data were analyzed using quantitative data analyses to achieve research objectives.

Findings
The results from the structural model assessment revealed that both internal and external physical environments elicited emotional well-being, which in turn leads to the increased guest satisfaction and retention. More specifically, internal atmospherics had a stronger impact on triggering subsequent variables compared to external environment factors. The outcomes also indicated the significant mediating role of emotional well-being and satisfaction. Emotional well-being was found to mediate the effect of internal and external physical environments on guest satisfaction, while guest satisfaction mediated the effect of emotional well-being on guest retention. Moreover, price perception significantly moderated the guest satisfaction–guest retention association. Overall, the proposed conceptual framework satisfactorily accounted for variance in guest retention.

Originality/value
The findings help practitioners in luxury resort hotels to develop ways to boost guests’ post-purchase behaviors by using internal/external atmospherics and emotional well-being.
Closing the researcher-practitioner gap
Authors: Hall Hazel , Cruickshank Peter , Ryan Bruce 
Published: June 2019

PurposeThe purpose of this paper is to investigate the extent to which learning gained through participation in three research methods workshops funded by an Arts and Humanities Research Council networking grant was applied in practice.Design/methodology/approachData were collected by online survey and focus group from individuals who participated in the Developing Research Excellence and Methods (DREaM) project workshops in 2011/2012. The survey data were coded and analysed manually, as were the transcribed focus group discussions.FindingsFollowing the conclusion of the DREaM project the participants at the core of the network applied their learning from the workshops to innovate in the workplace and to develop information services, with evident impact on end-users of library and information services. The strongest impact of the DREaM project, however, was found in reports of widened opportunities for the researcher and practitioner cadre members, many of which arose from collaborations. This provides evidence of a second proven strategy (in addition to the provision of research reports in practitioner publications) for narrowing the library and information science (LIS) research-practice gap: the creation of researcher-practitioner networks.Research limitations/implicationsCollaborative interactions between academic researchers and practitioners bring benefits to both network participants themselves and to the wider communities with which they interact. These are likely to be applicable across a range of subject domains and geographies.Practical implicationsNetwork grants are valuable for furnishing learning that may be applied in practice, and for bridging the research-practice gap.Social implicationsIn LIS and other domains that suffer from a research-practice gap (e.g. teaching, social work, nursing, policing, management) the bringing together of researchers and practitioners in networks may address problems associated with misunderstandings between the two communities, and lead to improved services provision.Originality/valueThis study provides an evaluation of network development that goes beyond simply reporting changes in network topology. It does so by assessing the value that network relationships provide to individuals and groups, extending knowledge on mechanisms of collaborative interaction within research networks. It is also the first detailed study of the impact of a UK research council networking grant.

Authors: Bertella Giovanna , Vidmar Benjamin 
Published: June 2019

PurposeThe purpose of this paper is to provoke reflections on the potential contribution of food tourism experiences to achieving the sustainable development goals for eradicating hunger and malnutrition.Design/methodology/approachIn line with the creative analytic practice in scientific inquiry, this study develops and discusses a futuristic scenario inspired by a factual company. The case is based on ideas derived from studies on educational and food tourism and entrepreneurship, more precisely ecopreneurship.FindingsFood tourism can offer an opportunity for discussing food challenges in the context of ideas and projects to alleviate hunger and malnutrition. This study shows that imagining such possibilities and projects is challenging because of the complexity of the issue.Practical implicationsThis study suggests that despite some limitations, educational food tourism experiences might go well beyond the issues of regional development, localism and authenticity. Practitioners, including tourism entrepreneurs and private and public food and tourism organisations, might be essential to exploring alternative food tourism futures in ways that truly contribute to urgent global challenges.Originality/valueThe value of this paper lies in the use of a scenario to imagine and to reflect on the future of food tourism in relation to the global challenges of hunger and malnutrition. The paper suggests that the ideas from tourism studies and ecopreneurship can offer interesting perspectives on future developments in the sector.

Published: June 2019

AbstractCutaneous gnathostomiasis (CG) is a disease caused by ingestion of third‐stage Gnathostoma larva in raw snakes, freshwater fish or frogs. The common causative organisms of CG in Japan include G. nipponicum, G. spinigerum, G. doloresi, G. binucleatum and G. hispidum. We report two cases of CG after eating many raw Japanese icefishes (Salangichthys microdon). In both cases, linear itchy eruptions on the trunk developed after eating many S. microdon. We performed genetic analysis in the first case, which revealed G. nipponicum. Of note, this is the first case of CG diagnosed based on genetic analysis in Japan. In Japan, eating whole small raw freshwater fish is common. The most popular types of raw small freshwater fish consumed in Japan are S. microdon (shirauo in Japanese) and Leucopsarion petersii (shirouo in Japanese). Usually, S. microdon are born in rivers, but live in both the sea and rivers. They feed on small fish and freshwater water fleas and spawn in rivers in the spring. On the other hand, L. petersii are born in rivers, but move to the sea soon after hatching. They feed on plankton such as copepod in the sea. They do not feed on anything when they return to rivers to spawn in the spring. Therefore, we hypothesize that S. microdon are more easily parasitized by G. nipponicum.
Droughts and the ecological future of tropical savanna vegetation
Authors: Sankaran Mahesh 
Published: June 2019

Abstract

Climate change is expected to lead to more frequent, intense and longer droughts in the future, with major implications for ecosystem processes and human livelihoods. The impacts of such droughts are already evident, with vegetation dieback reported from a range of ecosystems, including savannas, in recent years.

Most of our insights into the mechanisms governing vegetation drought responses have come from forests and temperate grasslands, while responses of savannas have received less attention. Because the two life forms that dominate savannas—C3 trees and C4 grasses—respond differently to the same environmental controls, savanna responses to droughts can differ from those of forests and grasslands.

Drought‐driven mortality of savanna vegetation is not readily predicted by just plant drought‐tolerance traits alone, but is the net outcome of multiple factors, including drought‐avoidance strategies, landscape and neighborhood context, and impacts of past and current stressors including fire, herbivory and inter‐life form competition.

Many savannas currently appear to have the capacity to recover from moderate to severe short‐term droughts, although recovery times can be substantial. Factors facilitating recovery include the resprouting ability of vegetation, enhanced flowering and seeding and post‐drought amelioration of herbivory and fire. Future increases in drought severity, length and frequency can interrupt recovery trajectories and lead to compositional shifts, and thus pose substantial threats, particularly to arid and semi‐arid savannas.

Synthesis. Our understanding of, and ability to predict, savanna drought responses is currently limited by availability of relevant data, and there is an urgent need for campaigns quantifying drought‐survival traits across diverse savannas. Importantly, these campaigns must move beyond reliance on a limited set of plant functional traits to identifying suites of physiological, morphological, anatomical and structural traits or “syndromes” that encapsulate both avoidance and tolerance strategies. There is also a critical need for a global network of long‐term savanna monitoring sites as these can provide key insights into factors influencing both resistance and resilience of different savannas to droughts. Such efforts, coupled with site‐specific rainfall manipulation experiments that characterize plant trait–drought response relationships, and modelling efforts, will enable a more comprehensive understanding of savanna drought responses.

AbstractThe role as well as the molecular mechanisms of protectin DX (PDX) in the prevention of hepatic insulin resistance, a hallmark of type 2 diabetes, remains unknown. Therefore, the present study was designed to explore the direct impact of PDX on insulin resistance and to investigate the expression of fetuin‐A and selenoprotein P (SeP), hepatokines that are involved in insulin signalling, in hepatocytes. Human serum levels of PDX as well as fetuin‐A and SeP were determined by high‐performance liquid chromatography (HPLC). Human primary hepatocytes were treated with palmitate and PDX. NF‐κB phosphorylation as well as expression of insulin signalling associated genes and hepatokines were determined by Western blotting analysis. FOXO1 binding levels were measured by quantitative real‐time PCR. Selected genes from candidate pathways were evaluated by small interfering (si) RNA‐mediated gene suppression. Serum PDX levels were significantly (P < 0.05) downregulated, whereas serum fetuin‐A and SeP levels were increased (P < 0.05) in obese subjects compared with healthy subjects. In in vitro experiments, PDX treatment increased AMP‐activated protein kinase (AMPK) phosphorylation and SIRT1 expression and attenuated palmitate‐induced fetuin‐A and SeP expression and insulin resistance in hepatocytes. AMPK or SIRT1 siRNA mitigated the suppressive effects of PDX on palmitate‐induced fetuin‐A through NF‐κB and SeP expression linked to FOXO1 and insulin resistance. Recombinant fetuin‐A and SeP reversed the suppressive effects of fetuin‐A and SeP expression on palmitate‐mediated impairment of insulin signalling. The current finding provides novel insight into the underlying mechanism linking hepatokines to the pathogenesis of hepatic insulin resistance.
Flexible manipulation of Omb levels in the endogenous expression region of Drosophila wing by combinational overexpression and suppression strategy

Published: June 2019

AbstractManipulating an exogenous or endogenous gene of interest at a defined level is critical for a wide variety of experiments. The Gal4/UAS system has been widely used to direct gene expression for studying complex genetic and biological problems in Drosophila melanogaster and other model organisms. Driven by a given tissue‐specific Gal4, expressing UAS‐transgene or UAS‐RNAi (RNA interference) could be used to up‐ or down‐regulate target gene expression, respectively. However, the efficiency of the Gal4/UAS system is roughly predefined by properties of transposon vector constructs and the insertion site in the transgenic stock. Here, we describe a simple way to modulate optomotor blind (omb) expression levels in its endogenous expression region of the wing disc. We co‐expressed UAS‐omb and UAS‐omb‐RNAi together under the control of dpp‐Gal4 driver which is expressed in the omb expression region of the wing pouch. The repression effect is more sensitive to temperature than that of overexpression. At low temperature, overexpression plays a dominant role but the efficiency is attenuated by UAS‐omb‐RNAi. In contrast, at high temperature RNAi predominates in gene expression regulation. By this strategy, we could manipulate omb expression levels at a moderate level. It allows us to manipulate omb expression levels in the same tissue between overexpression and repression at different stages by temperature control.
Host–pathogen interaction after infection of Galleria mellonella with the filamentous fungus Beauveria bassiana
Authors: Vertyporokh Lidiia , Hułas‐Stasiak Monika , Wojda Iwona 
Published: June 2019

AbstractThe filamentous fungus Beauveria bassiana is a natural pathogen of the greater wax moth Galleria mellonella. Infection with this fungus triggered systemic immune response in G. mellonella; nevertheless, the infection was lethal if spores entered the insect hemocel. We observed melanin deposition in the insect cuticle and walls of air bags, while the invading fungus interrupted tissue continuity. We have shown colonization of muscles, air bags, and finally colonization and complete destruction of the fat body—the main organ responsible for the synthesis of defense molecules in response to infection. This destruction was probably not caused by simple fungal growth, because the fat body was not destroyed during colonization with a human opportunistic pathogen Candida albicans. This may mean that the infecting fungus is able to destroy actively the insect's fat body as part of its virulence mechanism. Finally, we were unable to reduce the extremely high virulence of B. bassiana against G. mellonella by priming of larvae with thermally inactivated fungal spores.

AimThe aim of this study was to comprehensively assess dietary intake, nutrition knowledge and food addiction in young people with mental illness.MethodsThis was a three‐arm cross‐sectional study of 16–25‐year‐olds attending community mental health services who met criteria for: (i) first‐episode psychosis (FEP), (ii) ultra‐high risk for psychosis (UHR) or (iii) depression/anxiety. Participants self‐completed three validated questionnaires: (i) Australian Eating Survey, (ii) General Nutrition Knowledge Questionnaire—Revised and (iii) Yale Food Addiction Score Questionnaire.ResultsThirty participants (mean age 19.7 ± 2.5 years) completed the study (10 per study arm); 43% of the energy intake was obtained from energy‐dense, non‐nutritious foods, higher than the recommended upper limit (<15%) and the levels reported in the general population (35%). Mean diet quality score was 33.5 ± 11.8 of 73. Mean food addiction symptom score was 3.3 ± 3.7. Prevalence of food addiction was 37%. Nutrition knowledge was lower in the FEP and UHR participants than the depression/anxiety group (48.2 ± 13.8 and 49.5 ± 8.2 of 88 respectively); however, this difference was not statistically significant.ConclusionsUnhealthy dietary intake was observed in the early stages of mental illness, likely seeding future poor physical health. Further research is needed on the role of food addiction in this population, including effective intervention techniques.
