Scabies, caused by an infestation of the skin with the itch mite (Sarcoptes scabiei), is highly contagious and classified as a prevalent neglected tropical diseases. The current diagnostic approach relies solely on clinical judgment based on symptoms, history, and microscopic observation by an experienced dermatologist. To enhance sensitivity and specificity, we developed an alternative method based on mite-derived DNA. Our method involves a quick DNA release from skin scraping samples and Loop-Mediated Isothermal Amplification (LAMP) targeting the scabies mite-specific DNA sequences, enabling diagnosis within 30 minutes. Importantly, no cross-reactivity was observed when the sample was contaminated by two house dust mite species, and false positives were barely detected. Currently, we are in the process of developing a Point-of-Care Testing (POCT) kit for a scabies survey targeting school-age children in Timor-Leste as a global health project.

Silage inoculants, crucial in modern silage production, comprise beneficial microorganisms, primarily lactic acid bacteria (LAB), strategically applied to forage material during ensiling. This study aimed to compare the effectiveness of various inoculants produced by different companies. Five treatments were evaluated, including a control group: T1 (Lactobacillus plantarum), T2 (Lactobacillus plantarum + Pediococcus pentosaceus), T3 (Lactobacillus plantarum + Pediococcus pentosaceus + Lactobacillus buchneri), T4 (Lactobacillus plantarum + Lactobacillus acidophilus + Lactobacillus bulgaricus), and T5 (Lactobacillus plantarum + Pediococcus pentosaceus + Enterococcus faecium). Italian ryegrass was harvested at the heading stage and treated with these silage inoculants. Samples were collected over a 60-day ensiling period. Co-inoculation with L. plantarum and P. pentosaceus (T2) resulted in significantly higher CP compared to the control group co-inoculation exhibited with resulted in Lactobacillus plantarum and Pediococcus pentosaceus in the T2 treatment exhibited higher CP content of 106.35 g/kg dry matter (DM). The T3 treatment, which included heterofermentative bacterial strains such as Lactobacillus buchneri, exhibited an increase in acetic acid concentration (11.15 g/kg DM). In the T4 treatment group, which utilized a mixed culture of Lactobacillus acidophilus and Lactobacillus bulgaricus, the NH3-N/TN content was observed to be the lowest (20.52 g/kg DM). The T5 containing Enterococcus faecium had the highest RFV (123) after 60 days. Expanding upon these findings, the study underscores not only the beneficial effects of particular inoculant treatments on silage quality but also underscores the potential of customized inoculation strategies in maximizing nutrient retention and overall silage preservation.

This research investigated the preparation of activated carbon derived from Krabok (Irvingia malayana) seed shells to improve the quality of crude glycerol obtained during biodiesel production. The activated carbon was prepared using a dry chemical activation method with NaOH, utilizing an innovative biomass incinerator. The results revealed that the resulting KC/AC-two-step exhibited favorable physicochemical adsorption properties, with a high surface area of 758.72 m2/g and an iodine number of 611.10 mg/g. These values meet the criteria of the industrial product standard for activated carbon No. TIS 900-2004, as specified by the Ministry of Industry in Thailand. Additionally, the adsorption efficiency for methylene blue reached an impressive 99.35 %. This developed activated carbon was then used to improve the quality of crude glycerol obtained from biodiesel production. The experimental results showed that the KC/AC-two-step increased the purity of crude glycerol to 73.61 %. In comparison, commercially available activated carbon (C/AC) resulted in a higher crude glycerol purity of 81.19 %, as analyzed by the GC technique. Additionally, the metal content (Zn, Cu, Fe, Pb, Cd, and Na) in purified glycerol using KC/AC-two-step was below the standards for heavy metals permitted in food and cosmeceuticals by the Food and Drug Administration of Thailand and the European Committee for Food Contact Materials and Articles. As a result, it can be inferred that Krabok seed shells have favorable properties for producing activated carbon suitable as an adsorbent to enhance crude glycerol purity. Furthermore, the improved crude glycerol from this research has potential for various industrial applications.

Marine industry generates tons of waste, which is usually discarded or used for production of fish feed and low-value silage. However, marine residual raw materials (e.g., skins, heads, liver, and roe after fish gutting and processing) contain lipids rich in omega-3 fatty acid, which has several beneficial physiological effects such as maintenance of normal cardiac function, normal brain function, and normal vision. Food fortification with omega-3 fatty acid derived from marine residual raw materials can therefore provide health benefits and contribute to a circular food system. The current research explores consumer acceptance of the food fortified with microencapsulated fish oil derived from marine residual raw materials. Consumers may be hesitant to try these products due to food neophobia associated with tendency to eat foods with familiar ingredients. The idea of ingredients from normally discarded food parts may seem disturbing. However, there is a growing concern about low utilization of bioresources. Thus, conflicting goals may be in place and there is a need for research on motivations and barriers for consumption of this type of food. To address this, focus group interviews were conducted with 42 Norwegian consumers (7 groups, 4-7 participants each). The sample represented different age groups (20-55 years), genders, educational backgrounds, and income levels. Each participant received a compensation of ca. USD 30. The focus groups discussed food habits, attitude towards the fortified food and utilizing residual raw materials, and reasons for intake/no intake of such food. The interviews were transcribed and analyzed using the constant comparative method. The results indicate that the informants have limited experience with fortified food. However, they demonstrate positive attitude towards the foods fortified with microencapsulated fish oil and appreciate the utilization of residual raw materials. Health benefits are one of the important motivations. Still, the informants are concerned about the fishy taste, as the flavor is also quite crucial. Another barrier is an expected high price for such food. Adding fish oil may also be a problem for vegetarians and consumers with allergies. Thus, transparent information about the food ingredients is essential. The results also highlight the importance of food’s sensory characteristics. The current study advances understanding of the consumer acceptance of the food with residual raw materials (so far under investigated in the literature), and thus provides a basis for finding an efficient strategy for communicating its benefits to consumers. It also provides societal health benefits and positive environmental effects due to the increased intake of omega-3 and better utilization of unused bioresources.

It is difficult to optimize the process parameters of directly preparing carbonaceous mesophase (CMs) by solvothermal method using coal tar as raw material. To solve this problem, a Decision Tree model for CMs preparation (DTC) was established based on the relationship between the process parameters and the yields of CMs. Then, the importance of variables in the preparation process for CMs was predicted, the relationship between experimental conditions and yields was revealed, and the preparation process conditions were also optimized by the DTC. The prediction results showed that the importance of the variables was raw material type, solvothermal temperature, solvothermal time, solvent amount, and additive type in order. And the optimized reaction conditions were as follows: coal tar was pretreated by decompress distillation and centrifugation, the solvent amount was 50.0 ml, the solvothermal temperature was 230 °C, and the reaction time was 5 h. These prediction results were consistent with the actual experimental results, and the error between the predicted yields and the actual yields was about − 1.1%. Furthermore, the prediction error of DTC method was within the acceptable range when the data sample sets were reduced to 100 sets. These results proved that the established DTC for chemical process optimization can effectively lessen the experimental workload and has high application value.

Herein, a facile bottom–up approach for producing nitrogen-doped carbon quantum dots (N-CQDs) was carried out by the hydrothermal treatment of microcrystalline cellulose, in the presence of different nitrogen sources (blank/urea/ammonia water/ethanediamine(EDA)/Hexamethylenetetramine). The result showed that the fluorescence intensity and quantum yields (QYs) of N-CQDs with different nitrogen sources are all higher than that without nitrogen source. Compared with the other three nitrogen sources, N-CQDs prepared by EDA not only have the highest fluorescence intensity but also the largest QYs of 51.39%. Therefore, EDA was chosen as the nitrogen source to prepare N-CQDs. The obtained N-CQDs are uniform spherical particles with a diameter of 2.76 nm. The N-CQDs also exhibit excitation-dependent and long-wave emission properties. The emission range of N-CQDs is 470–540 nm. Moreover, N-CQDs as fluorescent agents successfully acted on purple LEDs (λem = 365 nm) to achieve white LEDs light emission. At the same time, a fluorescent thin layer chromatography plate was successfully prepared using N-CQDs, silica gel G and Sodium carboxymethylcellulose as raw materials. The separation trajectory of mixed sample of Sudan red III and kerosene on the fluorescent TLC plate is obviously clearer than that of the TLC plate.

This paper examined farmers’ perceptions and preferences for improved varietal traits in the Wenchi and Offinso North Municipalities of Ghana. Data from 306 randomly selected tomato farmers were analyzed using perception indices, Kendall’s Coefficient of concordance and the Poisson regression model. The results show that tomato farmers are willing to adopt an improved variety with long shelf life, good fruit quality and large fruit size. The study further indicates that tomato farmers lack requisite skills in pest and disease management. The number of varietal attributes preferred by farmers was positively influenced by sex of farmer, education, experience in tomato cultivation, household size, access to credit, FBO membership, extension contacts farm size and off-farm income. These factors and attributes need to be carefully considered by breeders and policy makers in the development of an improved tomato variety to enhance its uptake. The major constraints identified in tomato production include limited access to capital followed by low commodity prices coupled with low demand with the least constraint being access to tractors for land preparation. The potential of adoption of improved tomato varieties in Ghana will be augmented through paragenetic measures towards addressing these constraints.

Introduction Business event are much important to economies of many destinations all over the world (Jago, Mair, Deery, & Bergin-Seers, 2008). As the term, “business events” is referred to be the MICE industry, encompassing with Meeting, Incentive, Conference/Convention, and Exhibition. The MICE industry underpins tourist visitation for many destinations. Such destinations have transferred into making substantial investments to provide the meeting/exhibition facilities and hotel needed for business events. Announced in the 5th of MICE and Luxury Travel Conference, India will generate 6.5 million outbound incentive tourists by 2030. Especially in these years, the number of MICE outbound tourists has been more than 1.5 million and the number of Luxury travel tourists has been up to 3.6 million (India Infoline Housing Finance Limited [IIFL], 2017). Research for one of the business events that remains in minority is incentives. Incentive travel, also known as IT, is defined as one of worldwide management tools which uses special travel experiences or recognizes participants who exceed the expectation on performance (Society of Incentive Travel Executives [SITE], 2013). According to the Incentive Federation, the number of U.S. business using non-cash rewards has raised dramatically from just 26% in 1996 to 84% of all U.S. businesses in 2016 (Incentive Federation, 2017). Incentive travel is becoming a field in which not only attractions and venues matter, but also the organization of parallel training activities and conferences around an incentive activity is possible (Celuch, 2014). The United States remains a primary destination for 82% of U.S. planners choosing U.S. in 2017 (Incentive Federation, 2017). Another popular incentive destination, Australia is also viewed as one of ideal destinations for incentive travel. Tourism Australia in 2008 indicated that 34% of incentive travelers is from China, 12% is from New Zealand, and 10% is from Japan. Taiwan has received over 10 million travelers from abroad in 2016. However, tourists from India traveling to Taiwan are only 33,000 passengers. According to report in 2016, International Congress & Conference Association [ICCA] announced that Taipei City has held 83 international conference and become top 10 destinations in Asia for The Best Stop to Meet Asia. However, is Taiwan a good incentive travel destination for India? Despite a limited amount of information on expenditure and the number of incentive programs, numerous gaps remain in our understanding of this sector of business events and cross-culture marketing, including how incentive travel organizers in India select their travel destination? And how this process may differ in source markets? This exploratory study aims to examine these site selection factors in the incentive travel context and identify any similarities and differences in how incentive travel is conceptualized, planned, and organized in India. Literature review Incentive Travel The incentive market has seldom been studied in great depth as an individual segmentation. Lewis (1983) carried out a concept that incentive travel represents a sizable market segment for hotel companies in many destination areas. Sheldon (1995) highlighted that travel was regarded as a motivating reward or incentive among America’s Fortune 100 companies, and that travel incentives were mostly used by companies in the service sector. Shinew and Backman (1995) identified the “trophy value” of travel incentives, and proposed that incentive travel allows long-lasting positive engagement in staffs’ job performance. Xiang and Formica (2007) used cognitive mapping to understand how incentive travel managers view the business environment, concluding with fast-pacing of incentive travel market, and global structural changes presenting challenges to incentive planners. Budget and cost, uniqueness of the destination, and availability of suitable facilities were thought to be factors influencing the choice of destination for incentive travel (Mair, 2005); however, this has not yet been demonstrated in empirical research. Convention Site Selection According to Crouch and Ritchie (1997) “the choice of destination can make or break the convention”. The first research by Fortin and Ritchie (1977) was considered the process undertaken by meeting planners when deciding on which location to choose for annual meeting or convention. The nine factors identified by Crouch and Ritchie (1997) are accessibility, local support, extra-conference opportunities, accommodation, meeting facilities, information, site environment and other criteria. Despite knowledge of the convention site selection process, very little research has considered how different types of meetings choose their destinations. In one of the few studies to consider the site selection process of incentive planners, Del Chiappa (2012) suggests a certain degree of “destination inaccessibility” could make incentive location being more extraordinary and exclusive. Mair, Jin, and Yoo (2016) indicated that incentive travel planners across three market- China, Australia, and America, shares similar perceptions on what characterizes incentive trips but differ slightly in the planning and operational phase pertinent to varying company characteristics and requirements. However, little is known about the cultural differences in incentive programs from one nation to the next. Methodology This research is an exploratory qualitative research, using in-depth interviews with incentive travel organizers, public relations professionals, company and staff who has participated in incentive travel to Taiwan and other Asian countries. Eight in-depth interviews (between 30 and 60 minutes) were carried out in India. The data collecting method is snowball sampling and 11 interviewees were invited by incentive organizers’ recommendations, while a list of qualified tour operators/specialists authorized by national tourism bureaus and organization (e.g., Ministry of Tourism Government of India or Travel Agents Association of India Active Member) are consulted as a sample frame, shown as table 1. Further, all interviewees were senior managers in their companies. For in-depth interviews, researcher has traveled to Mumbai, New Delhi and Jamshedpur in India between 12th and 26th Jan, 2018. Interviewees were asked to give some background on their incentive business. They were also asked to give information on how their incentive programs were structured and how they cooperate both with their incentive clients and with local suppliers of their incentive trips. Finally, they were asked in open-ended questions about their views on site selection, with eight site selection factors identified by Crouch and Ritchie (1997) and the outline designed by Mair, et al (2016). Findings This study explored site selection of incentive travel from the perspective of incentive planners, company, and participants. The finding suggests that the most popular incentive travel destination for Indian is Thailand with low expense and luxury hospitality. Most important part for choosing a destination is considering about food and beverage since there are a lot of vegetarian and chef should be familiar with Indian cuisine, for instance, foods in Singapore is more likely to be accepted by Indian. Both the operators and staffs from the company indicate that Indian travelers would like to have Indian cuisine and Bollywood show during the incentive trips, instead of local and cultural performance from the destination. Conference and accommodation facilities in China is well-prepared for MICE but expense is too high. Accessibility to Taiwan or to any countries won’t be a problem for incentive travel planners; nevertheless, there is still few direct flight from India to Taiwan which will influence the budget on overseas transportation. In addition, unfamiliarity with destination image of Taiwan reduces intention of visiting. However, since a new destination will be a motivator for encouraging employees to work hard, novelty destination for incentive trip is still important. One incentive travel planners suggest that enhancing the destination image by story-telling would help attracting Indian’s interests. Perceived risk will be reduces depending on local support (DMC). Incentive planners in India illustrate although decision maker is the representatives from companies, however, planners would give several packages of different countries, depending on budgets, basing on destination information from public relations professionals. It is obvious that public relations professionals and travel agencies are critical characters for site selection in India. F&B and budget are major considerations differing from other markets- China, Australia, and America. Conclusions This article interviewed incentive operators, public relations professionals, and company purchase incentive travel, and examined how incentive travel is conceptualized, planned, and organized in India. The study suggests government and bureau relating to MICE should get well prepared for cross-cultural incentive traveler, according to Indian culture. In addition, destination imagine promotion would be another effort for planners to select a site for incentive program. Since incentive planners in India are not familiar with Taiwan, local support/ DMC could look for public relations professionals from India as a connection, and put more focus on India as a potential market. Further study should explore the site selection in different countries, and marketing strategies. A limitation of this research that should be acknowledged is the small sample size. However, the initial conclusions from this research suggest that, while the site selection factors identified in other markets provide a useful place to start, incentive travel organizers do not rely on same factors. The findings from this project will provide a basis for future research in the area of incentive, and useful information for incentive planners/organizers in Taiwan and worldwide.

Introduction Although hotel employees are trained to deliver the best service, service failures may happen at any time because service is delivered by people to people (Susskind, 2002). Moreover, customers are more impressed by failed services than good services (Titz, 2001). According to the recovery paradox, customers have higher satisfaction level after experiencing a service failure if they receive satisfactory service recovery or compensation (McCollough & Bharadwaj, 1992). With the development of information communication technology and mobile device, customers can receive personalized services in recent days (Migacz, Zou, & Petrick, 2018). They also can easily share their experience on the online review platforms such as TripAdvisor, as well as select hotels based on shared online reviews (Liu & Park, 2015; Nieto-Garaía, Muñoz-Gallego, & González-Benito, 2017). Therefore, it is important for hotel managers to understand the mechanisms for service failure and recovery strategy. Thus, this study aims to examine the relationship between different emotion, customer engagement and brand loyalty under the context from the luxury hotels in China that different service failure compensation strategies are adopted. Particularly, the following two research questions are aimed to be addressed: First, do emotions (anger, regret and helplessness) significantly affect hotel brand loyalty through customer engagement? Second, does compensation type (immediate vs. delayed) significantly affect customer engagement and hotel brand loyalty based on customers’ emotions? The results of this study will benefit industry practitioners for formulating effective service failure recovery strategies. Theoretical frameworks and hypotheses development Stimulus-Organism-Response framework Stimulus-Organism-Response (S-O-R) framework is a commonly used form of behavioral research in which events or occurrences are said to be the result of certain stimulus leading to a certain response, following a set of organism processes (Kim & Lennon, 2013; Mehrabian & Russell, 1974). In behavioral research, the S-O-R theory explains “how” something happens and a variance theory describes “why” (Chiles, 2003). We adopted the S-O-R framework in an attempt to explain the effect of the compensation types (immediate vs. delayed) on hotel brand loyalty. In our research model, customer engagement is used an intervening construct on the causal relationship between emotions of customer (anger and regret as a retrospective emotions, helplessness as a prospective emotion) (Gelbrich, 2010) and hotel brand loyalty. Customer engagement is composed of multidimensional concepts of identification, enthusiasm, attention, absorption, and interaction (So, King, & Spark, 2014). Our model thus explains four basic processes of relationship impact on service failure as “stimulus”, emotions and customer engagement as “organism”, and hotel brand loyalty as “response”. This study also emphasizes compensation type as “moderator”. The model shows how to enhance the understanding of emotions that affect hotel brand loyalty through customer engagement based on the moderating effect of compensations type. Customer engagement It is important for a firm to manage customers to improve a firm’s performance. Customer management has transformed from customer transactions, to relationship marketing, and then engaging customers (Pansari and Kumar 2017). There are different definition about customer engagement and most of them define customer engagement as the activity of the customer toward the firm. For example, Pansari and Kumar (2017) define customer engagement as how customer contributes to the firm by “the mechanics of a customer’s value addition to the firm, either through direct or/and indirect contribution.” Vivek et al. (2012) define customer engagement as “the intensity of an individual’s offerings or organizational activities, which either the customer or the organization initiates” (p.127). It has been discussed that customer engagement has been affected by customer emotion and also has significant impact on behaviour intention and brand loyalty. However it has not been discussed under service failure context and when different types of compensation strategies are employed. This study therefore aims to explore this mechanics. Under hospitality context, So, King and Sparks (2014) develop five factors to measure customer engagement: identification, enthusiasm, attention, absorption, and interaction. Since this study also examine hotel guest customers, we adopt the scale of So et al. (2014) due to its comprehensiveness and consistent context. Service failure and emotion Customer emotion is an important antecedent of customer engagement. Currently firms have been shifted their focus from selling products to emotional connection with their customers (Pansari and Kumar 2017). Positive emotion may enhance customer engagement and thereby improve customer loyalty. But when service failure occurs, customers have different negative emotions including anger, frustration, helplessness, regret amongst others. These negative emotions of customers disappoint customers themselves and reduce customer loyalty. Different emotions may have different impact on customer engagement. Anger often refers to the attributes of others such as the service providers (Weiner, 1985) whereas regret often refers to the service failure locus of customer himself/herself such as the customer is regret to choose this service provider (Roseman, 1991). Both anger and regret refer to retrospective emotions and when customer would like to solve questions they may also negative emotion of helplessness which is called prospective emotions (Davidow, 2003; Gelbrich, 2010). This study aims to examine and differentiate the impact of two retrospective emotions of anger and regret and one prospective emotions of helplessness. The first hypothesis is therefore proposed: H1: Anger has negative impact on customer engagement. H2: Regret has negative impact on customer engagement. H3: Helplessness has negative impact on customer engagement. Service failure compensation Though service providers aim to deliver zero fault service, it is inevitable service failure may occur that may bring customers anger and dissatisfaction and damage the customer loyalty thereby. It is found that compensation is an effective way to comfort and delight the dissatisfied customers. Therefore, it is important to formulate effective compensation strategy when service failure occurs. Different compensation strategies such as monetary or nonmonetary (Fu et al. 2015), immediate or delayed compensation (Boshoff, 1997; Davidow, 2003), may be suitable to different contexts/situations. According to prospect theory, a customer is risk-reverse in case of gains. A customer may value products available now more than products obtained in the future due to the higher certainty of the former. Similarly, immediate compensation has less uncertainty than delayed compensation, and therefore is supposed to have higher value. Therefore customers with anger are assumed to have higher customer engagement when immediately compensated. On the other hand, regret customers attribute failure to himself/herself and therefore less expect compensation. The immediate compensation may lead to unfair and thereby less effect than delayed compensation. Therefore immediate compensation may not always be superior over the delayed one under different contexts. We therefore propose the second hypothesis: H1a: Compensation type (immediate vs. delayed) moderates the relationship between anger and customer engagement. H2a: Compensation type (immediate vs. delayed) moderates the relationship between regret and customer engagement. H3a: Compensation type (immediate vs. delayed) moderates the relationship between helplessness and customer engagement. Brand loyalty Brand loyalty refers to the loyalty of a customer toward the brand both behaviourally and attitudinally (Dick and Basu 1994; Li and Petrick 2008; So, King, Sparks, and Wang 2013). It is a key goal of marketing activities, and its antecedents have been extensively examined such as satisfaction, perceived quality, received value, and brand trust, amongst others. Customer engagement, as the activity of a customer toward to a firm, is naturally viewed to influence brand loyalty. This study therefore adopts brand loyalty as the consequence of customer engagement. Furthermore, we would like to examine if compensation types have moderating effect between customer engagement and brand loyalty. We therefore propose below two hypotheses: H4: customer engagement has positive impact on brand loyalty. H4a: Compensation type (immediate vs. delayed) moderates the relationship between customer engagement and brand loyalty. The research model is shown in Figure 1 where all hypotheses are demonstrated. Our research model is developed based on the S-O-R framework in which emotions are antecedent of customer engagement, and customer engagement impacts hotel brand loyalty. This research model also shows the moderating effects of compensation types has on causal relationships between the aforementioned constructs. Methodology Scenario design Scenario based questionnaire is designed to obtain quantitative data for analysis. Based on the interview with hotel managers/operators, one service failure scenario and two compensation scenarios (immediate and delayed) are designed. In-depth interviews with a couple of hotel managers and guests were conducted to verify the realisation of the scenarios formulated. The questionnaire begins with a screening question: in the previous 12 months have you ever had experience staying in a four- or five-star hotel? The survey would only continue if the answer is “yes”. Then the participant is asked to write down the name of this hotel and read the below service failure scenario thereby. Service failure scenario: Imagine you have checked into this hotel again. During your stay in hotel, you send your coat for laundry. It is a nice coat and you bought it a year ago with the price of 1000RMB. However when you collect the cleaned coat, you notice that there is a damage on your coat which makes you cannot dress this coat anymore. You therefore call the service counter for complain. Immediate and delayed compensation scenarios were designed as follows: Immediate compensation scenario: after 15 minutes, the duty manager of the hotel went to our hotel and expressed his sincere apology. You showed him about the damage and informed him the original price of your coat. The manager offered you the cash compensation with the original price of your coat and you agree with this. After half an hour you received 1000RMB cash as the compensation. Delayed compensation scenario: after 15 minutes, the duty manager of the hotel went to your room and expressed his sincere apology. You showed him about the damage and informed him the original price of your coat. The manager said according to the hotel policy, they need to check how this happened and confirm the price of your coat first before making the compensation for you. After two weeks you left the hotel, you received 1000RMB compensation which is transferred into your bank account directly. Participant emotion is measured after the participants read the service failure scenario and before they read the compensation scenario. Each participant is randomly assigned to be involved in one compensation scenario only. Customer engagement and hotel brand loyalty are measured after the compensation happened. Variable measurement Customer engagement is measured using 25-item scale developed by So et al. (2014) in which five factors are involved: identification, enthusiasm, attention, absorption, and interaction. Particularly, identification is measured by four attributes: “When someone criticizes this brand, it feels like a personal insult”, “When I talk about this brand, I usually say we rather than they”. “This brand’s successes are my successes”. “When someone praises this brand, it feels like a personal compliment”. Enthusiasm is measured by five attributes: “I am heavily into this brand”. “I am passionate about this brand” “I am enthusiastic about this brand” “I feel excited about this brand” “I love this brand”. Attention is measured by five attributes: “I like to learn more about this brand” “I pay a lot of attention to anything about this brand” “Anything related to this brand grabs my attention” “I concentrate a lot on this brand” “I like learning more about this brand” . Absorption is measured by five attributes: “When I am interacting with the brand, I forget everything else around me” “Time flies when I am interacting with the brand” “When I am interacting with brand, I get carried away” “When interacting with the brand, it is difficult to detach myself” “In my interaction with the brand, I am immersed” “When interacting with the brand intensely, I feel happy”. Interaction is measure by five attributes: “In general, I like to get involved in brand community discussions” “I am someone who enjoys interacting with likeminded others in the brand community” “I am someone who likes actively participating in brand community discussions” “In general, I thoroughly enjoy exchanging ideas with other people in the brand community” “I often participate in activities of the brand community”. Three emotion of anger, regret and helplessness are included as the measurement of emotion. Particularly, according to Gelbrich (2010), three attributes are adopted to measure anger “I would feel angry with the hotel/hotel employees”, “I would feel mad with the hotel/hotel employees”, and “I would feel furious about the hotel/hotel employees”. Three statements are employed to measure regret (Tsiros & Mittal 2000): “I would feel sorry for choosing this hotel”, “I regretted choosing this hotel”, and “I should have chosen another hotel”. Four statements are used to measure helplessness (Gelbrich 2010): “I would feel helpless”, “I would feel lost”, “I would feel defenceless”, and “I would feel stranded.” Five statements are used to measure brand loyalty (So, King, Sparks, & Wang 2013): “I would say positive things about this brand to other people.” “I would recommend this brand to someone who seeks my advice.” “I would encourage friends and relatives to do business with this brand.” “I would consider this brand my first choice to buy services.” “I would do more business with this brand in the next few years.” A seven-point Likert scale ranging from 1 (=disagree strongly) to 7 (=agree strongly) is adopted for all measurement. Data collection and analysis method In-depth interview with managers from upscale hotels and customers will be used to finalize scenarios. Opinions of academic experts will be used to revise variable measurements and questionnaires. Convenience sampling method will be adopted to obtain about 400 respondents who has experience of staying at four- or five-stars hotels in China in the previous year. Regarding with data analysis, Partial least square structural equation modelling (PLS-SEM) is used to test the hypotheses proposed. Expected results The manipulation check has been conducted to verify the scenarios designed. The negative relationship between emotions and customer engagement are expected and compensation timing (delayed or immediate) may moderate this relationship. Most importantly, it is expected that this moderating effect varies when different emotions and customer engagement are examined. Contributions The theoretical contributions have three folders. Firstly, this study first considers compensation timing into the examination of relationship between different negative emotions and customer engagement, after service failure occurs. Secondly, this study adopts stimulus-organism-response theory to explore the mechanism how service failure could be well recovered by relationships of different negative emotions, effective compensation type, customer engagement, and brand loyalty. Thirdly, this study applies second order factor for the measurement of customer engagement and also divides negative emotions into retrospective and prospective ones to shed light on customer engagement in the context of service failure and compensation. The practical implication of this study will benefit industry practitioners for their formulation of compensation strategies. Especially as the development of big data, hotel industry is able to adopt different strategies for individuals to maximize customer experience. The findings of this study could propose different strategies for different situations/individuals thereby.

This study was conducted to examine the influences of two human chorion gonadotrophins (hCGs) being injected into young or aged (45- to 65-week old) outbred (ICR) mice on developmental capacity of oocytes retrieved. In vitro-culture and parthenogenetic activation of oocytes retrieved were employed for the assessment. Superovulation was determined as being induced when more than 25 oocytes were retrieved. No aged mice were superovulated, while in contrast, 67-100% were superovulated in the 6- to 8-week-old (young) mice. In the aged, hCG injection yielded better retrieval (5 vs. 13 to 14.8 oocytes/mouse). Overall, no significant difference between two hCGs was detected but between the young and aged, significant differences in maturational arrest (0% vs. 39% MI arrest and 46% vs. 15% degeneration) and developmental capacity (24% vs. 46% 8-cell embryo development) were detected. In conclusion, hCG injection contributes to increasing oocyte retrieval from aged outbred mice, but the kinds of gonadotrophin influenced the efficiency of hyperstimulation induction in specific ages.

The extragalactic background suggests half the energy generated by stars was reprocessed into the infrared (IR) by dust. At z1.3, 90% of star formation is obscured by dust. To fully understand the cosmic star formation history, it is critical to investigate infrared emission. AKARI has made deep mid-IR observation using its continuous 9-band filters in the NEP field (5.4 deg2), using 10% of the entire pointed observations available throughout its lifetime. However, there remain 11,000 AKARI infrared sources undetected with the previous CFHT/Megacam imaging (r ~25.9ABmag). Redshift and IR luminosity of these sources are unknown. These sources may contribute signicantly to the cosmic star-formation rate density (CSFRD). For example, if they all lie at 1< z <2, the CSFRD will be twice as high at the epoch. We are carrying out deep imaging of the NEP eld in 5 broad bands (g; r; i; z; and y) using Hyper Suprime-Camera (HSC), which has 1.5 deg field of view in diameter on Subaru 8m telescope. This will provide photometric redshift information, and thereby IR luminosity for the previously-undetected 11,000 faint AKARI IR sources. Combined with AKARI's mid-IR AGN/SF diagnosis, and accurate mid- IR luminosity measurement, this will allow a complete census of cosmic star-formation/AGN accretion history obscured by dust.

Our understanding of dust emission, interaction, and evolution, is evolving. In recent years, electric dipole emission by spinning dust has been suggested to explain the anomalous microwave excess (AME), appearing between 10 and 90 Ghz. The observed frequencies suggest that spinning grains should be on the order of 10nm in size, hinting at polycyclic aromatic hydrocarbon molecules (PAHs). We present data from the AKARI/Infrared Camera (IRC) due to its high sensitivity to the PAH bands. By inspecting the IRC data for a few AME regions, we nd a preliminary indication that regions well-tted by a spinning- dust model have a higher 9 m than 18 m intensity vs. non-spinning-dust regions. Ongoing eorts to improve the analysis by using DustEM and including data from the AKARI Far Infrared Surveyor (FIS), IRAS, and Planck High Frequency Instrument (HFI) are described.

Technology-mediated communication is established as a key channel for firms to interact with consumers, who can choose between a rapidly expanding variety of devices types and interaction modes such as live-chats, video calls, voice-controlled virtual assistants, or online avatars. However, frustrated consumers report publicly about their negative experience and attribute their discontent to a lack of authenticity of the technology-mediated encounter. In technology-mediated contexts consumers often cannot relate to tangible products and observable behavior of a service employee to judge the authenticity of the encounter. Thus, it is unknown how consumers form their authenticity evaluation. We address this gap by exploring the concept of authenticity in technology-mediated consumer-firm interactions. Based on 41 qualitative in-depth interviews we provide a framework of consequences and antecedents of authenticity perception. Most importantly, we identify three different categories of cues from which consumers infer to judge the authenticity of an encounter: the interaction counterpart, the communication quality and the brand experience

This study addresses the influence of corruption on firm innovation in Chinese market. Using both the logit model and a fuzzy-set analytical approaches based on a new official sample of 2700 privately-owned and 148 state-owned firms over the period of 2011 to 2013, the study add further evidence to growing methodological consideration regarding complexity theory. The results show a significant negative effect of corruption on firm innovation, additional, firm sale and education and market have a positive bearing on innovation activity. However, the government ownership firms have a negative and significant effect on innovation. The findings have important implication for theory, practitioners and policy-making and shed light on a new perspective to focus on the long run effect of corruption.
