With the rapid development of niche tourism, green tourism activity has become known to the wider public. By taking into account the extended theory of planned behaviour (TPB), this study takes natural dyeing experience as a case study, with the aim of determining the tourist purchase intention of green products under the destination experience scenario. A quantitative approach was adopted, and 349 valid sets of data were collected from individuals who have participated in natural dyeing activities. Partial least squares–structural equation modelling (PLS–SEM) analysis was conducted to test the conceptual model. The results indicate that experience value (EV) had a significant impact on green purchase conception and intention. In addition, subjective norm had a significant positive influence on tourism green purchase attitude. However, environmental knowledge failed to predict green purchase attitude and perceived behavioural control. The PLS–SEM analysis confirmed the extended TPB model, which showed relatively good predictive validity. Findings suggest that TPB mediated the relationship between EV and purchase intention. The extended model considerably contributes to improving understanding of the impact on green tourism products and dissects theoretical and practical implications to practitioners. Apart from strengthening the experience value from attaining, learning, escapism, and fantasy aspects, on the basis of previous literature, this study concludes that practically, environmental education regarding the experimental environment in tourism destinations in China should return to green activity itself and induce the support of green tourism products. Tourism marketers should trigger personal green knowledge through sense experience in the process of stimulating and promoting green tourism activities, as well as stimulate purchasing power.

ObjectiveAccurate diagnosis and prognosis of frontotemporal lobar degeneration (FTLD) during life is an urgent concern in the context of emerging disease-modifying treatment trials. Few CSF markers have been validated longitudinally in patients with known pathology, and we hypothesized that CSF neurofilament light chain (NfL) would be associated with longitudinal cognitive decline in patients with known FTLD-TAR DNA binding protein ~43kD (TDP) pathology.MethodsThis case-control study evaluated CSF NfL, total tau, phosphorylated tau, and β-amyloid1-42 in patients with known FTLD-tau or FTLD-TDP pathology (n = 50) and healthy controls (n = 65) and an extended cohort of clinically diagnosed patients with likely FTLD-tau or FTLD-TDP (n = 148). Regression analyses related CSF analytes to longitudinal cognitive decline (follow-up ∼1 year), controlling for demographic variables and core AD CSF analytes.ResultsIn FTLD-TDP with known pathology, CSF NfL is significantly elevated compared with controls and significantly associated with longitudinal decline on specific executive and language measures, after controlling for age, disease duration, and core AD CSF analytes. Similar findings are found in the extended cohort, also including clinically identified likely FTLD-TDP. Although CSF NfL is elevated in FTLD-tau compared with controls, the association between NfL and longitudinal cognitive decline is limited to executive measures.ConclusionCSF NfL is associated with longitudinal clinical decline in relevant cognitive domains in patients with FTLD-TDP after controlling for demographic factors and core AD CSF analytes and may also be related to longitudinal decline in executive functioning in FTLD-tau.

Purpose– This paper aims to investigate the benefits derived from sustainable office buildings in People’s Republic of China (PRC) through their green features, with particular reference to energy efficiency.Design/methodology/approach– A survey on operating costs, energy impacts, productivities from property managers and tenants of sustainable office buildings was conducted in Shenzhen, PRC. All survey data were collected from a portfolio of 12 sustainable office buildings and from 76 responses out of more than 400 tenants who had moved into these buildings from conventional office buildings.Findings– Most tenants were concerned with sustainable operations, practices and policies. Some of them held that sustainable office buildings contribute to higher productivity and less sick time. These buildings typically consume less electricity and water, and have higher occupancy rates and rents.Research limitations/implications– There are only 40 sustainable office buildings in Shenzhen, and our study, albeit with proper methodology, with 12 sample buildings may not reflect entirely the attitudes of tenants and property managers of sustainable office buildings in Shenzhen. Advisably, future works can be carried out on a larger scale in other main cities of PRC to obtain a more comprehensive and precise evaluation on which strategic sustainable central/local government policies might be formulated.Originality/value– The concept of facilities management on sustainable buildings, especially on their derived benefits, is relatively new in developing countries such as China. This study is one of the first attempts in this area. In addition, this paper also contributes to existing literature by looking into the green lease provisions and operating policies of these sustainable buildings.
