Abstract: The consumption of wine is influenced by seemingly contradictory antecedents such as perceived authenticity and novelty. This paper aims to explore the influence novelty and authenticity have on wine consumption, in the context of the moderating variables of regionality (i.e. single and multi-region wines) and price (low and high). The research attempts to further understand wine consumption by establishing a conceptual model built on existing wine literature. To address the hypotheses and research questions, a panel of 658 consumers who regularly purchased wines produced by the Australian wine industry were recruited. These participants completed a self-administered questionnaire containing stimuli to measure perceived authenticity, perceived novelty, perceived quality, attitudes and purchase intent towards a wine manipulated to have a low vs high price level, as well as single vs multi-regional label. To examine these variables, the study conducted a confirmatory factor analysis (CFA) to confirm the dimensionality of the constructs and structural equation modeling with both path and multi-group analyses to investigate the hypothesised relationships. The findings revealed that both authenticity and novelty simultaneously influence perceived quality. Additionally, it was acknowledged that there is no significant difference in wine consumption between single and multi-regional wines reinforcing current trends of collaboration within the wine industry. Finally, the results also showed that price does moderate wine consumption revealing ideal prices for wine with particular regional branding strategies. The current research is the first to show that authenticity and novelty simultaneously and positively influence consumer’s perceived quality of Australian wine. The findings are also the first to show that consumer evaluation of single and multi-origin wines was positive and yielded no significant difference, suggesting that branding wines with multi-origins or multi-region do not change consumers’ perception.

Abstract: Hydrodistillation was used to obtain the essential oil from pomelo (Citrus grandis L.) peels collected in Vietnam. The effects of extraction variables including size of material, temperature, extraction time, and water-to-material ratio on the yield of essential oil were investigated. In addition, to assess the quality of pomelo essential oil, the chemical composition was compared. The optimized conditions were as follows: material size of grind, temperature 120 °C, water to material ratio 5 mL/g, and extraction time 105 min., respectively. The chemical composition of the pomelo oil was then determined by GC-MS, where 5 components were identified, of which, limonene was the highest (97.1%). This method can be considered as a green method of extraction method as it is less energy intensive process and offers high performance. The results are expected to aid in justification of hydrodistillation in industrial applications and in refining of extraction parameters.

Abstract: Gac fruit contains extraordinarily high levels of carotenoids that are well-known as strong antioxidants with an attractive yellow-orange-red colour. The aim of this study was to investigate the effects of different pre-treatments and air drying temperatures on colour characteristics, total carotenoid content (TCC) and total antioxidant activity (TAA) of resultant Gac fruit powder. Results showed that pre-soaking in solutions of ascorbic acid or bisulfite prior to air drying at low temperature of 40°C was effective in preserving TCC and TAA. Loss of TCC and TAA increased as drying temperatures increased (50, 60, 70, and 80°C). Moreover, the colour characteristics of Gac powder, such as chroma and hue angle, were not significantly affected by pre-treatments and air drying temperatures. The sorption isotherm curve of Gac aril powder has sigmoid shape.

Abstract: The purpose of this paper is to examine the predictive power of anger and its associated appraisal dimensions of consumer responses to two different public relations incidents. A natural quasi-experiment was conducted within a month after the public relations incidents. Participants randomly viewed one of the two videos relating to the incidents. Path analysis was used to examine the direct and indirect effects of anger, acceptability appraisal, motivational incongruence appraisal, relevance appraisal and other accountability appraisal on consumers’ intention to harm the brand and future purchase intention. Appraisals of acceptability, motivational incongruence and relevance, but not other accountability, have both direct and indirect effects on anger and its motivational tendency. Acceptability appraisal directly increases consumers’ intention to harm, whereas relevance appraisal directly increases their intention to harm and reduces future purchase intention. The degree to which these appraisal structure and anger occur account for the level of negative consumer responses toward the two public relations incidents. The current findings empirically replicate the erse consumer responses toward two public relations incidents and use anger and its appraisal structure to account for the negative responses. This provides researchers and practitioners a framework to explain and manage consumers’ reaction toward different public relations incidents. The current findings not only support the motivational role of anger and its accompanying appraisals in public relations incidents, but also demonstrate their predictive power in the given contexts.

Abstract: Four different factors involved in the aqueous enzymatic extraction of the bioactive compounds, including total polyphenols, total flavonoids, total saponins, and vitamin C, from ultrasound pretreated noni (Morinda citrifolia L.) powder were examined. The study showed that the most suitable enzymatic extraction conditions for the content of the bioactive compounds were obtained at the concentration of enzyme (mixture of pectinase and cellulase, at 1:1, w/w) at 0.5% dry weight (d.w.), the water-to-powder ratio of 16/1 (mL/g), and the incubation temperature at 60oC for 45 min when ultrasonic pretreatment was fixed at 50 ± 5˚C for 10 min. Under those conditions, the highest content of total polyphenols, flavonoids, saponins, and vitamin C was found to be 12.53 ± 0.09 mg GAE/g d.w., 6.45 ± 0.61 mg QE/g d.w., 56.02 ± 2.45 mg AE/g d.w., and 1.04 ± 0.09 mg AA/g d.w., respectively. For comparison, the results indicated that the application of ultrasound and enzymes has shown to be effective in improving aqueous extraction. Therefore, it can be concluded that the present extraction method is a novel and green alternative method for extracting bioactive compounds from noni fruit.

Abstract: The aim of the study was to explore the feasibility of using telepresence robots to encourage interactive communication in dementia care, from the perspective of family carers. Qualitative findings from semi-structured interviews with six family carers. Generally, family carers reported a feeling of presence and connectedness when talking to their family member via the telepresence robots. They reported the robots as helping to enhance longer conversations and social connection with their family member. Telepresence may offer potential to encourage social connection, in particular where families are unable to make regular visits to the nursing home.

Abstract: Consumers are known to show a paradoxical tendency to favour both familiar and novel marketing stimuli such as products and advertisements. However, an explanation for this paradox has yet to be proposed. This provides immense challenges for marketing practices that conventionally strive to build familiarity (e.g. building awareness, recognition, recall, and customer relationships). Using the emotion differentiation framework, this theoretical paper shows that this paradox is a result of two distinct emotions – liking and interest. Specifically, consumers like familiarity but are interested in novelty. This paper offers six empirical propositions to: (1) differentiate interest from liking (2) show that liking motivates consumers to favour familiarity whereas interest motivates consumers to prefer novelty (3) demonstrate that interest accounts for previously explained boundary conditions of the familiarity–liking effect and (4) provide insights to explain previous conflicting findings in the field of innovation, advertising, and consumer psychology research.

Abstract: This study aims to examine why online consumers watch Mukbang, a type of South Korean online entertainment show, by exploring the antecedents of consumers’ attitude toward Mukbang from a cross-cultural perspective. Data was collected from 114 Asians and 129 Caucasian participants using a self-administered questionnaire online. Data was then analysed using structural equation modelling. Similarities and differences were noted for both the s les. The findings show that Asians tend to watch Mukbang due to host attractiveness and social normative influence, while Caucasians watch such shows due to host attractiveness, perceived novelty and social normative influence. Practical implications are provided for traditional and digital marketers, advertisers and broadcast jockeys so they are better equipped with insights on online consumer behaviour, marketing strategies and conceptualisation of videos.

Abstract: Lime juice is rich in bioactive components and exerts a wide range of therapeutic effects, especially antioxidant activity. Freeze concentration is considered an essential method to maintain the nutritional values and bioactives of fruit juices. This study aimed to compare the ability in enriching ascorbic acid, total phenolic compounds, and major flavonoids and the antioxidant activity (DPPH) of concentrated lime juices prepared by vacuum and freeze-concentrations. The ascorbic acid in the juices was analyzed using the HPLC-PDA method. The total phenolic content and DPPH inhibition ability were measured by the colorimetric method. The polyphenol profiles of two lime varieties (C. latifolia and C. limonia) were qualitatively analyzed using LC-TOF MS/MS then, the major juices’ flavonoids were analyzed by HPLC-PDA against/based on commercial standards. The results showed that C. latifolia was superior to C. limonia in ascorbic acid, TPC, major flavonoids, and antioxidants. C. latifolia was also more erse than C. limonia in its polyphenol profile through the identified compounds (18 vs. 15). Freeze-concentrated lime juices were significantly higher than the vacuum-concentrated counterparts in ascorbic acid (mean difference from 9.41 to 22.01 mg, p 0.01), and TPC (from 60.76 to 149.88 mgGAE). The quantification of major flavonoids showed that the freeze-concentrated lime juices retained high levels of hesperidin, eriocitrin, and rutin (p 0.01) whereas the vacuum concentration preserved higher ones in diosmin and naringin (p 0.01). The freeze-concentrated lime juice was significantly higher than vacuum-concentrated lime juices in the DPPH scavenging activity by at least 15% (p 0.01). Overall, freeze concentration enriched bioactive compounds in lime juices almost threefold and improved antioxidants at least twofold. Thus, freeze concentration is promising for the industry in producing high-quality lime juice to preserve its thermal liable bioactive component.

Abstract: Skin-transmitted pathogens have threatened humans since ancient times. We investigated whether skin-transmitted pathogens were a subclass of disgust stimuli that evoked an emotional response that was related to, but distinct from, disgust and fear. We labelled this response "the heebie jeebies". In Study 1, coding of 76 participants' experiences of disgust, fear, and the heebie jeebies showed that the heebie jeebies was elicited by unique stimuli which produced skin-crawling sensations and an urge to protect the skin. In Experiment 2,350 participants' responses to skin-transmitted pathogen, fear-inducing, and disgust-inducing vignettes showed that the vignettes elicited sensations and urges which loaded onto heebie jeebies, fear, and disgust factors, respectively. Experiment 3 largely replicated findings from Experiment 2 using video stimuli (178 participants). Results are consistent with the notion that skin-transmitted pathogens are a subclass of disgust stimuli which motivate behaviours that are functionally consistent with disgust yet qualitatively distinct.

Abstract: The study aimed to optimise the ultrasound-assisted aqueous extraction of oil, β-carotene and lycopene from powdered microwave-dried gac arils. Ultrasound power, extraction time, powder particle size and the ratio of water to gac powder during the extraction, the centrifugal force used to recover the extracted components were investigated. Microwave-drying followed by aqueous extraction without ultrasound-assistance and air-drying followed by aqueous extraction with or without ultrasound-assistance was also carried out for comparisons. The gac material left behind after the extractions was also investigated using scanning electron microscopy (SEM). The results showed that ultrasound power of 32 W/g of aril powder, extraction time of 20 min, powder particle sizes of 0.3–0.5 mm, a ratio of water to powder of 9 g/g and a centrifugal force of 6,750× g gave optimal extraction efficiencies for oil (90%), β-carotene (84%) and lycopene (83%), and the oil had a low peroxide value (PV) of 2.2 meq/kg. The SEM analysis confirmed that the combination of microwave-drying followed by ultrasound-assisted aqueous extraction caused strong disruption of the gac aril cellular structures, which was consistent with the high extraction of oil, β-carotene and lycopene obtained with the combination. It was concluded that gac oil containing high amounts of β-carotene and lycopene and having a low PV could be extracted using microwave-drying and ultrasound-assisted aqueous extraction.

Abstract: Gac fruit ( Momordica cochinchinensis Spreng) aril contains high levels of bioactive compounds including β-carotene, lycopene and fatty acids. Therefore, it is important to find an extraction method of Gac oil resulting in the highest content of bioactive compounds. The effects of microwave and air-drying pre-treatments of Gac aril prior to hydraulic pressing and Soxhlet extraction on the oil yield, nutrients and chemical properties of the oil were compared. Results showed that the highest oil yield could be obtained when the aril was microwave-dried before Soxhlet extraction. This finding was explained by microstructural changes of the dried arils. Microwave-drying prior to pressing resulted in the highest content of β-carotene (174 mg/100 mL) and lycopene (511 mg/100 mL) in the oil extract. Oleic acid (48%) and linoleic acid (18%) were found to be the dominant fatty acids in the oil extracts. Gac oil with the lowest acid (0.69 mg KOH/g) and peroxide values (1.80 meq O 2 /kg) was extracted when microwave-drying was applied prior to pressing. It can be concluded that the microwave drying pre-treatment before pressing was better than the air-drying pre-treatment for extracting Gac oil of high quality.

Abstract: To develop and psychometrically test the Engagement of a Person with Dementia Scale. It is important to study engagement in people with dementia when exploring the effectiveness of psychosocial interventions that can promote meaningful activity, stimulation and well-being, through an increase in positive emotions and an improvement in quality of life. The Engagement of a Person with Dementia Scale was developed based on current literature and previous research work on a video coding tool to ascertain the effect of psychosocial interventions on engagement in people with dementia. Using the Delphi technique, the content validity of the scale was evaluated by 15 dementia experts and formal/informal dementia carers. Psychometric properties of the scale were evaluated using 131 videos of people with dementia presented with PARO-a therapeutic, interactive, robotic seal-in long-term aged care facilities. A 10-item scale was established following the rewording, combining and elimination of prospective items, with revisions made to the instructions for using and scoring the scale. An overall consensus with agreement for the scale was established among the panel of experts. The scale demonstrated robust internal consistency, inter-rater and test-retest reliability and convergent and discriminant validity. This study successfully developed the Engagement of a Person with Dementia Scale, with established content validity and psychometric properties. The scale assesses the behavioural and emotional expressions and responses of engagement by people with dementia when partaking in a psychosocial activity in five areas: affective, visual, verbal, behavioural and social engagement.

Abstract: Lime ( Citrus latifolia ) juice concentrate is rich in vitamin C and phenolic compounds exerting a range of health benefits. Spray drying converts fruit juice into powder and offers convenience for industrial applications. The appropriate spray drying conditions for lime juice prepared by freeze concentration are rarely reported. Thus, this study aimed to investigate the effects of inlet temperature (130-170°C) and feed flow rate (20-40 mL/min) on drying yield, total ascorbic and phenolic contents (TPC) of the dried lime powder from spray drying of freeze-concentrate lime juice (containing 22% solid). The inlet drying temperature influenced the yield, total ascorbic acid and phenolic contents of the lime powders. The drying using an inlet temperature of 130°C resulted in the dried lime powder with ascorbic acid and phenolic contents of 113.1 mg/100 g and 1268 mgGAE/100 g, respectively and an acceptable yield (90.1%). The most appropriate feed flow rate was 30 mL/min which resulted in lime powder with high yield, total ascorbic acid and phenolic content. In conclusion, the high-quality spray-dried powder can be processed at the 130°C inlet temperature and 30 mL/min of feed flow rate. At these conditions, the obtained powder had a 45% lime solid and suitable moisture content (4.5%) and water activity ( 0.25) that would be stable for storage.

Abstract: It is well-known that bioactive compounds have many positive advantages for human health. The extension of their shelf life and their applications in the food and pharmaceutical sectors are important issues. Microencapsulation is one of the proven methods to protect bioactive compounds and enable various applications. In this chapter, microencapsulation technology, including the important steps of understanding the physicochemical properties of the bioactive compounds, selection of suitable encapsulation, and microencapsulation methods, is presented. Understanding of physicochemical properties of bioactive compounds and wall materials is the first important step. There are a variety of microencapsulation methods that can be selected to encapsulate the bioactive compounds, depending on the application purpose of the resultant microencapsulated product. In addition, the release rate and release mechanism of microencapsulated particles also play an important role, determined by the selection of wall materials and microencapsulation methods. Finally, methods to evaluate the physicochemical stability of the solution before microencapsulation and the characterization of the microencapsulated particles are also presented. Several ex les of successful encapsulation technology and recommendations for further studies of the bioactive compounds are also reported throughout the chapter.& nbsp br

Abstract: Neuroimaging technologies such as electroencephalogram and magnetic resonance imaging allow us to analyze consumers’ brains in real time as they experience emotions. These technologies collect and integrate data on consumers’ brains for big data analytics. The purpose of this paper is to identify new opportunities and challenges for neuromarketing as an applied neuroscience. The authors discuss conceptual and methodological contributions of neuromarketing based on studies that have employed neural approaches in market-related investigations, explaining the various tools and designs of neuromarketing research. The authors identify marketing-related questions to which neuroscientific approaches can make meaningful contributions, evaluating several challenges that lie ahead for neuromarketing. The authors summarize the contributions of neuromarketing and discuss synergistic findings that neuromarketing has the potential to yield. The authors ask: do consumers’ self-reported choices and their neural representations tell different stories? what are the effects of subtle and peripheral marketing stimuli? and can neuromarketing help to reveal the underlying causal mechanisms for perceptual and learning processes, such as motivation and emotions? The authors identify marketing-related questions to which neuroscientific approaches can make meaningful contributions, evaluating several challenges that lie ahead for neuromarketing. To the best of the authors’ knowledge, no current review has identified avenues for future research in neuromarketing and the emerging challenges that researchers may face. The current paper aims to update readers on what neuroscience and other psychophysiological measures have achieved, as well as what these tools have to offer in the field of marketing. The authors also aim to foster greater application of neuroscientific methods, beyond the more biased ost-test methods such as self-report studies, which currently exist in consumer research.

Abstract: Do consumers really like familiarity and therefore dislike novelty? This is a central question that has resonated through different fields of marketing and psychology. Past research has found that people heuristically associate familiarity to liking, but they also prefer novelty in certain motivational contexts. This paper presents three studies to show that novelty does not result in liking but instead, evokes interest—a similar but functionally different positive affective experience. Specifically, we show that people feel interested toward and therefore favour a product when it is subjectively perceived to be new or said to be new, even when the novel product is objectively identical to its counterpart. Novelty, however, was found to be unrelated to liking. These findings suggest that consumers’ paradoxical tendency to favour both familiarity and novelty is manifested in ways beyond a general emotional valence account. Specifically, familiarity appears to evoke liking whereas novelty appears to evoke interest.

Abstract: Previous research has indicated that frontal midline theta (FMθ) reflects a domain-general cognitive control mechanism of the prefrontal cortex. Brain imaging studies have shown that the inhibition of implicit stereotypes was dependent on this domain-general cognitive control mechanism. Based on this knowledge, the present study investigated the neural oscillatory correlates of implicit gender stereotype control in an extrinsic affective Simon task (EAST) using electrophysiological methods. Participants in this task conducted verification to white gender names and colored gender traits, and their behavioral response and electroencephalogram (EEG) were recorded during their performances. As predicted, stereotype-inconsistent trials resulted in reduced response accuracies and slower response times than stereotype-consistent trials. For the event-related potential (ERP) results, the enhanced performance of stereotype-inconsistent trials was accompanied by an enhanced N400 litude but an attenuated late positive potential litude. In contrast, early attentional components such as P2 and N2 as well as their litudes were impacted by the experimental manipulations and in idual differences in gender factors. In addition, based on time–frequency (TF) analysis, we found that the enhanced performance of stereotype-inconsistent trials was also accompanied by an event-related synchronization on the frontal theta oscillation. This frontal theta appeared at a late processing stage and persisted across a time window from N400 to late positive potential. Additionally, this enhanced frontal theta effect was not modulated by the experimental manipulations and in idual differences in gender factors. Based on these findings, the feature of frontal theta oscillation in the implicit gender stereotype control process was discussed.

Abstract: Contact researchers have overlooked (a) the mechanisms that explain the association between negative contact and prejudice, (b) the effects of positive and negative contact on outcomes beyond prejudice, and (c) the importance of testing contact effects cross-culturally. In the present article, we addressed these gaps in the literature by drawing on data from White Americans ( N = 207 Study 1), Hong Kong Chinese ( N = 145 Study 2), and Buddhist Thais ( N = 161 Study 3). Specifically, we examined positive and negative contact as predictors of old-fashioned and modern prejudice toward, and negative metaperceptions about, Black Americans, Mainland Chinese, and Muslim Thais, respectively. We also tested intergroup anxiety as a mediator of the associations between positive and negative contact, and all intergroup outcomes. Across three studies, positive contact predicted reduced intergroup anxiety, prejudice, and negative metaperceptions, while negative contact predicted increased intergroup anxiety, prejudice, and negative metaperceptions. Negative contact, however, was the more consistent predictor of intergroup attitudes. Intergroup anxiety emerged as a robust mediator of the relationships between both types of contact and all intergroup outcomes. We thus present the first test of a model of positive and negative contact that holds across both Western and non-Western contexts.

Abstract: Theory proposes that interest is a positive emotion that may either broaden attention to facilitate processing of new information, or narrow attention to preserve engagement with new information. To our knowledge, no research has directly examined the effect of interest on attentional scope. Across four experiments, we show that traits associated with the propensity to experience interest-specifically, trait curiosity and internal boredom proneness-are associated with a narrower scope of attention. We also find that, instead of broadening, interest actually narrows attentional scope in comparison to a neutral state and awe. Challenging the conventional notion that all positive emotions broaden cognition and attention, our findings suggest that specific emotions influence attention in ways that extend beyond a general emotional valence effect.

However, the assessment of engagement for people with dementia in relation to our current work that uses social robots is fraught with challenges. The Video Coding - Incorporating Observed Emotion (VC-IOE) protocol that focuses on six dimensions of engagement: emotional, verbal, visual, behavioral, collective and signs of agitation was therefore developed. This paper provides an overview of the concept of engagement in dementia and outlines the development of the VC-IOE to assess engagement in people with dementia when interacting with social robots.

Abstract: Gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter, plays a role in regulating neuronal excitability. Polyphenols naturally occur in plants and help to prevent or reverse damage in cells caused by aging, the environment, and lifestyle. Edible sprouts such as mung beans are a valuable source that presents high content of bioactive compounds. These contents in raw mung beans are very low, but they increase significantly during germination. The objectives of this study were to determine the most appropriate germination conditions, including air relative humidity (80%, 90%, and 99%), salt concentrations (0, 0.5%, 1.0%, and 1.5%), and light conditions (dark, LED, and UV-C) during the soaking and incubation processes to maximize the content of GABA and polyphenols. The results showed that all investigated treatments (air relative humidity, salt, and light) increased GABA and polyphenol levels, but LED lighting and air relative humidity of 90% were the most effective. Under those conditions, the content of GABA and polyphenols in the germinated mung beans increased about 12 and 2 times, respectively. Furthermore, the changes in GABA and polyphenol contents were different under different soaking and incubation conditions. In conclusion, the nutritional quality of mung beans, in terms of GABA and polyphenols, could be improved by controlling light and air relative humidity during germination. It is also recommended that the germination conditions, including air relative humidity, soaking in water or salt, soaking time, and incubation time should be selected depending on the desired content of GABA or polyphenols.
