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.

Understanding visitors' level of engagement with tourist attractions is vital for successful heritage management and marketing. This paper develops a scale to measure visitors' level of engagement in tourist attractions. It also establishes a relationship between the drivers of engagement and level of engagement using Partial Least Square, whereby both formative and reflective scales are included. The structural model is tested with a sample of 625 visitors at Kelvingrove Museum in Glasgow, UK. The empirical validation of the conceptual model supports the research hypotheses. Whilst prior knowledge, recreational motivation and omnivore-univore cultural capital positively affect visitors' level of engagement, there is no significant relationship between reflective motivation and level of engagement. These findings contribute to a better understanding of visitor engagement in tourist attractions. A series of managerial implications are also proposed.

Interface engineering of organic-inorganic halide perovskite solar cells (PSCs) plays a pivotal role in achieving high power conversion efficiency (PCE). In fact, perovskite photoactive layer needs to work synergistically with the other functional components of the cell, such as charge transporting/active buffer layers and electrodes. In this context, graphene and related twodimensional materials (GRMs) are promising candidates to tune "on demand" the interface properties of PSCs. In this work, we fully exploit the potential of GRMs by controlling the optoelectronic properties of hybrids between molybdenum disulfide (MoS2) and reduced graphene oxide (RGO) as hole transport layer (HTL) and active buffer layer (ABL) in mesoscopic methylammonium lead iodide (CH3NH3PbI3) perovskite (MAPbI3)-based PSC. We show that zero-dimensional MoS2 quantum dots (MoS2 QDs), derived by liquid phase exfoliated MoS2 flakes, provide both holeextraction and electron-blocking properties. In fact, on the one hand, intrinsic n-type doping-induced intra-band gap states effectively extract the holes through an electron injection mechanism. On the other hand, quantum confinement effects increase the optical band gap of MoS2 (from 1.4 eV for the flakes to > 3.2 for QDs), raising the minimum energy of its conduction band (from -4.3 eV for the flakes to -2.2 eV for QDs) above the one of conduction band of MAPbI3 (between -3.7 and -4 eV) and hindering electron collection. The van der Waals hybridization of MoS2 QDs with functionalized reduced graphene oxide (f-RGO), obtained by chemical silanization-induced linkage between RGO and (3-mercaptopropyl)trimethoxysilane, is effective to homogenize the deposition of HTLs or ABLs onto the perovskite film, since the two-dimensional (2D) nature of RGO effectively plug the pinholes of the MoS2 QDs films. Our "graphene interface engineering" (GIE) strategy based on van der Waals MoS2 QD/graphene hybrids enable MAPbI3-based PSCs to achieve PCE up to 20.12% (average PCE of 18.8%). The possibility to combine quantum and chemical effects into GIE, coupled with the recent success of graphene and GRMs as interfacial layer, represents a promising approach for the development of next-generation PSCs.

The energy band edge positions of MoS2 flakes and MoS2 QDs were determined from OAS and UPS measurements detailed along the text, while those of the other materials were taken from literature: FTO, 52 TiO2, 52 MAPbI3, 134-139 spiro-OMeTAD 52 and Au 52 .

Purpose The purpose of this study is to review and synthesise recent studies in the sharing economy literature and identify the knowledge gap and future opportunities for hospitality and tourism researchers. Design/methodology/approach The study commences by introducing sharing economy models and strategic frameworks for profitable service enabler performance. Following this, it identifies emerging overarching theories (e.g. complexity theory, social exchange theory, norm activation model, and value co-creation) and some emerging themes (i.e. trust and reputation, disruptive behaviour, choice and segmentation, pricing strategies, socially excluded consumers, personality and satisfaction) in current hospitality and tourism studies from top-tier journals. Findings The findings of the study suggest new paths for advancing theoretical and practical implications for hospitality and tourism studies. Practical implications The themes, models and overarching theories reviewed in this study are relevant and insightful across the fulcrum of hospitality and tourism research. It offers several useful guides for practitioners and academics to trace relevant literature on different aspects of sharing economy and perceptibly highlight the gaps in existing studies. Originality/value The paper provides new directions to broaden interdisciplinary and multidisciplinary approaches undertaken by scholars within both the field of hospitality and tourism management and beyond.

Interface engineering is performed by the addition of graphene and related 2 D materials (GRMs) into perovskite solar cells (PSCs), leading to improvements in the power conversion efficiency (PCE). By doping the mesoporous TiO layer with graphene flakes (mTiO +G), produced by liquid-phase exfoliation of pristine graphite, and by inserting graphene oxide (GO) as an interlayer between the perovskite and hole-transport layers, using a two-step deposition procedure in air, we achieved a PCE of 18.2 %. The obtained PCE value mainly results from improved charge-carrier injection/collection with respect to conventional PSCs. Although the addition of GRMs does not influence the shelf life, it is beneficial for the stability of PSCs under several aging conditions. In particular, mTiO +G PSCs retain more than 88 % of the initial PCE after 16 h of prolonged 1 sun illumination at the maximum power point. Moreover, when subjected to prolonged heating at 60 °C, the GO-based structures show enhanced stability with respect to mTiO +G PSCs, as a result of thermally induced modification at the mTiO +G/perovskite interface. The exploitation of GRMs in the form of dispersions and inks opens the way for scalable large-area production, advancing the possible commercialization of PSCs.

Framed by social exchange theory and Weber’s theory of substantive and formal rationality, this study investigates the mediating role of residents’ perceptions of tourism impacts. It examines whether community attachment, environmental and cultural attitudes, economic gain, and community involvement directly impact upon residents’ support for tourism development, or if their influences are mediated by perceptions of tourism impacts. Data were collected from residents within two historical cities in Iran: Kashan and Tabriz. The findings reveal that residents’ perceptions of tourism impacts play a significant mediating role in shaping the relationships between community attachment, environmental attitudes, and economic gain on support for tourism development. However, the results do not support the indirect effects of cultural attitudes and involvement on support for tourism development. This study thus extends extant knowledge by highlighting the mediating role played by residents’ perceptions of tourism impacts, comparing direct and indirect effects on support for tourism development.

Purpose Recognising tourists’ increasing desire for authentic destination-specific experiences, the hospitality industry has responded by increasing provision of innovative culinary activities. This study aims to use the concepts of serious leisure and terroir to examine how knowledge, physical environment and service quality influence co-creation within the culinary tourism context. Design/methodology/approach Following cooking class participation, 575 domestic Iranian tourists were surveyed. These educational classes provide opportunities to learn about local foods alongside peers in an interactive setting. Consistent with the benefits of serious leisure, this consumption context could prove conducive to stimulating co-creation. Findings Prior knowledge strongly influences tourists’ reflective and recreational motives for participation (i.e. the benefits of serious leisure). This shapes how tourists evaluate physical environments and service quality therein; influencing value co-creation and supporting serious leisure as the conceptual lens through which to understand experiential culinary consumption. Research limitations/implications The proposed conceptual model was tested on domestic tourists following class participation. However, in suggesting that visually-stimulating, tactile premises with the olfactory appeal can encourage co-created experiences, the findings are relevant to service touch-point management more generally. Originality/value Recognizing the influential role played by the physical and social aspects of experiential consumption, the serious leisure framework improves an extant understanding of value co-creation.
