Team project-based learning has become increasingly common in higher education. This study aimed to characterise and understand students' team learning experiences in team project-based learning by ...considering various aspects, such as individual qualities, teamwork, task, and instructor support. K-means clustering analysis was performed using eleven variables: team learning preference, co-regulation, team efficacy, team climate, team trust, psychological safety, team interaction, perceived team loafing, task authenticity, the frequency of instructor feedback, and usefulness of instructor feedback. Data were collected from students who were involved in team project-based learning at a South Korean university in the 2nd semester of 2021, and 782 responses were used in the analysis. Consequently, six clusters were identified, each showing different patterns of individual team learning attitudes and skills, teamwork, task authenticity, and instructor feedback. Following the cluster analysis, one-way ANOVA was performed, finding significant differences in team performance and team learning satisfaction between clusters. Based on these findings, important factors in team learning are discussed, and implications of enhancing team project-based learning are presented.
A recalled memory is deemed authentic when it accurately represents how one experienced the original event. However, given the convincing research in cognitive science on the constructive nature of ...memory, this inevitably leads to the question of the ‘bounds of authenticity’. That is, how similar does a memory have to be to the original experience to still count as authentic? In this paper we propose a novel account of ‘Situated Authenticity’ which highlights that the norms of authenticity are context-dependent. In particular, we show that each of the three core functions of episodic memory (self, social and directive) is correlated with patterned changes in levels of conceptualization (e.g., concrete construal versus abstract construal of the event). We support this theoretical account with existing empirical data. We conclude the paper by showing how our account of Situated Authenticity supplements ongoing discussions on memory contextualism, and providing an outline of how our account, which is currently elaborated targeting a phenomenological level, may also be elaborated on a processing level using the concept of representational format.
This article analyzes the tensions and dynamics which exist between “new” speakers and other speakers, such as traditional or native speakers of minority languages (MLs), in an attempt to discover ...just how much of a barrier to communication are the (perceived) differences which are purported to exist between them. The dynamics between “new” and native speakers seem to be complex and nuanced, and “(in)authenticity” can be indexed through accent, the lexicon and grammatical structures, both by local users and more widely by researchers and other interested third parties, reflecting a wide range of ideo-logical stances. Using a critical sociolinguistic framework, these differences are examined from the perspective of the power differentials among and between various ML speakers/users in two situations of language endangerment, Breton and Yiddish. The reproduction of “symbolic violence”, as described by Bourdieu (1991), which results from such differentials can hinder language revitalization projects and can run counter to the interests of the language community in question. Both settings appear to share a commonality of experience that is wider than just the two language communities under scrutiny here and possible ways of reconciling such differences are examined toward the end of the article.
Understanding the sense of authenticity of heritage attractions is important for tourism management and marketing because presentation, interpretation and verification has a direct bearing on ...motivations to visit and engage with heritage tourism sites. This paper establishes relationships among the concepts of culturally specific motivation, perception of authenticity, engagement and attendant behavioral consequences based on domestic visitors' experiences at Japanese heritage sites. It further extends Kolar and Zabkar's (2010) model of authenticity by including concepts of serious leisure, heritage related behaviors, self-connection and their effects over engagement using Partial Least Square, whereby both formative and reflective scales are included. The structural model is tested with a sample of 768 visitors in a culturally specific setting of Japanese heritage sites. The empirical validation of the conceptual model supports the research hypotheses. These findings contribute to a better understanding of visitors' perceptions and valuation of authenticity in Japanese tourist attractions. Several implications can be drawn from the study findings and interesting directions for future research are provided.

Purpose
This study aims to investigate consumer perceptions of inauthenticity due to adulteration of a narrative brand ending by using the research context of the final season and ending of the ...television series, Game of Thrones.
Design/methodology/approach
Two data sets totalling 2,032 online comments detailing consumer reactions to the final season of Game of Thrones were analysed using thematic analysis and human interpretive analysis. The coding was an iterative and continuous process, and posts were returned to and re-examined to refine codes and groupings as the analysis progressed.
Findings
The results indicate consumers perceived the ending of the eighth and final season of the television series, Game of Thrones, did not meet their expectations and was not authentic due to rushed writing and illogical character and plot developments. Consumers judged this adulteration was so great that it was a moral violation and transgression. Consumers also sought to assign blame for the inauthenticity, which they attributed to the writers and showrunners, who became the subject of revenge behaviours.
Originality/value
This study indicates consumers of narrative brands, due to their strong emotional attachments to their characters and storyworlds, may perceive unexpected and extensive changes to them as moral violations and transgressions and thus inauthentic. Consumers establish the authenticity of a narrative brand by regularly scrutinising narrative and character development against their expectations as shaped by prior narrative content. Due to their emotional attachment, consumers may attempt to attribute blame for the inauthenticity. The findings have not been established in prior research, and inauthenticity in a narrative brand context is also explored for the first time.
PurposeThe purpose of this paper is to find out how the overall destination experiences of the foreign tourists in India are influenced by the perceived authenticity of the street foods and the ...degree of their variation/modification. It will also discuss how these characteristics further influence the tourists’ behavioural intentions (intention to revisit and word-of-mouth).Design/methodology/approachData have been collected from 263 foreign tourists visiting Delhi at various street food vending sites using location intercept technique through structured questionnaire. Different ad hoc scales were adapted based on previous studies for measuring the perception of authenticity, ability to adapt, cultural disparity and overall perceived experience. The partial least squares method was applied to achieve the dual estimation of the measurement and the structural model.FindingsResult indicates that perceived authenticity and cultural disparity have a positive influence on the overall perceived experiences of the foreign tourists. It is also found that the degree of variation/modification in the street foods condenses the authenticity perception of the tourists. Findings reveal that the tourists are less influenced by the cultural disparity when they are able to adapt to diverse cultures and simultaneously authenticity have a larger effect on their overall destination experiences.Originality/valueAlthough various studies have been conducted in the past related to the food experiences of tourists at various destinations, this will be the first attempt to find out how the overall destination experiences of the foreign tourists in India are influenced by the perceived authenticity of the street foods and the degree of their variation/adaptation. It will help the stakeholders to appropriately align the gastronomic product and enhance the tourists’ overall destination experiences.
This study explores whether and how varying levels of social media influencers (SMIs) personal authenticity affect consumer behavior in four experimental studies. Though consumers who perceive SMIs ...as being authentic express greater intention to purchase products endorsed by the SMIs, authenticity does not influence non-purchase behaviors. SMI authenticity also affects purchase intentions through trustworthiness and inspirational capacity. However, authenticity is not always necessary to influence consumer behavior. Inauthentic SMIs still can inspire consumers and positively influence their intentions to purchase hedonic products. These findings add value to existing literature and can inform effective SMI marketing strategies for various product categories.
•Authentic social media influencer (SMI) increases consumer purchase intention.•SMI trustworthiness and inspiration sequentially mediate this relationship.•SMI personal authenticity has no effect on non-purchase related consumer behavior.•Inauthentic SMIs still can inspire consumers to purchase hedonic products.

Gas chromatography hyphenated to ion mobility spectrometry (GC-IMS) is a powerful, two-dimensional separation and detection technique for volatile organic compounds (VOC). Low detection limits, high selectivity and robust operation characterize it as an ideal tool for non-target screening (NTS) approaches. Combined with multivariate data analysis, it has been successfully applied to several areas in food science, such as authenticity control and flavor profiling. The recorded raw data feature high numbers of variables due to the high scan speeds of the instrument. Additionally, NTS approaches - by design - record more data than required. Therefore, reducing the number of variables is a key step in any machine learning pipeline to reduce overfitting, overlong training times and model complexity. The aim of the study is a comparison between the two most used dimensionality reduction techniques, PCA and PLS, regarding interpretability, as a tool to find marker compounds, and performance as a preprocessing step for supervised learning. Both feature per variable visualizations, which allows easy interpretation of results and retains a connection to the input data, which can lead to the discovery of marker compounds. A GC-IMS dataset about the botanical origin of honey is used, and all formatting steps necessary to apply PCA and PLS to higher dimensional data and obtain intuitive figures are explained. To evaluate effectiveness as a preprocessing step in a supervised pipeline four supervised algorithms were fitted with PCA or PLS variable reduction. PLS proved to be a more effective step in a supervised workflow in terms of accuracy, while PCA is highly effective for revealing preprocessing weaknesses such as misalignments.
A simple, sensitive, specific and fast method based on the loop-mediated isothermal amplification (LAMP) technique and cleavable molecular beacon (CMB) was developed for chicken authentication ...detection. LAMP and CMB were used for DNA amplification and amplicon analysis, respectively. Targeting the mitochondrial cytochrome b gene of chickens, five primers and one CMB probe were designed, and their specificity was validated against nine other animal species. The structure of CMB and concentrations of dNTPs, MgSO
4
, betaine, RNase H2, primers and CMB were optimized. The CMB-LAMP assay was completed within 17 min, and its limit of detection for chicken DNA was 1.5 pg μL
−1
. Chicken adulteration as low as 0.5% was detected in beef, and no cross-reactivity was observed. Finally, this assay was successfully applied to 20 commercial meat products. When combined with our developed DNA extraction method (the extraction time was 1 min: lysis for 10 s, washing for 20 s and elution for 30 s), the entire process (from DNA extraction to results analysis) was able to be completed within 20 min, which is at least 10 min shorter than other LAMP-based methods. Our method showed great potential for the on-site detection of chicken adulteration in meat.
