Spatial characteristics and restructuring model of the agro-cultural heritage site in the context of culture and tourism integration.

Tourism promotes the economic development of agro-cultural heritage sites while causing the problem of spatial alienation, so exploring the spatial alienation problems based on the integration of culture and tourism is of great significance for achieving the sustainable development of tourism in agro-cultural heritage sites. This study took the Yuanyang Hani Terrace agro-cultural heritage site as the research area, constructed the model of the spatial system of the agro-cultural heritage site based on the classical grounded theory, and analyzed the spatial characteristics of the agro-cultural heritage site. The results show that the spatial disorder of the agro-cultural heritage site is caused by the interaction of the imbalance of physical space, the fragmentation of cultural space and the complications of social space.

Visitor Engagement, Relationship Quality, and Environmentally Responsible Behavior.

Visitor environmentally responsible behavior (ERB) is helpful for promoting the sustainable development of tourist destinations. Existing studies on visitor ERB tend to either focus on restraining visitors' environmental misconducts or rely on visitors' psychological factors. Based on the theory of engagement, this paper constructs a theoretical model to explain visitors' self-conscious ERB.

Population exposure-response model to support dosing evaluation of ixekizumab in patients with chronic plaque psoriasis.

Ixekizumab (LY2439821), a humanized immunoglobulin G subclass 4 (IgG4) monoclonal antibody that selectively binds and neutralizes interleukin (IL) 17A has demonstrated efficacy in the treatment of psoriasis. A population pharmacokinetics-pharmacodynamics model was developed using NONMEM 7.2 to describe the temporal relationship between ixekizumab concentrations and absolute Psoriasis Area and Severity Index (PASI) scores from a phase 2 dose-finding study in chronic plaque psoriasis.

[Tourism function zoning of Jinyintan Grassland Scenic Area in Qinghai Province based on ecological sensitivity analysis].

Based on the statistical data of natural ecology and social economy in Jinyintan Grassland Scenic Area in Qinghai Province in 2008, an evaluation index system for the ecological sensitivity of this area was established from the aspects of protected area rank, vegetation type, slope, and land use type. The ecological sensitivity of the sub-areas with higher tourism value and ecological function in the area was evaluated, and the tourism function zoning of these sub-areas was made by the technology of GIS and according to the analysis of eco-environmental characteristics and ecological sensitivity of each sensitive sub-area. It was suggested that the Jinyintan Grassland Scenic Area could be divided into three ecological sensitivity sub-areas (high, moderate, and low), three tourism functional sub-areas (restricted development ecotourism, moderate development ecotourism, and mass tourism), and six tourism functional sub-areas (wetland protection, primitive ecological sightseeing, agriculture and pasture tourism, grassland tourism, town tourism, and rural tourism).

[Chlorophyll content and net photosynthetic rate of Machilus pauhoi and M. leptophylla].

By using SPAD-502 chlorophyll meter, LI-6400 portable photosynthesis system, and spectrophotometer, the leaf SPAD value, net photosynthetic rate (Pn), and chlorophyll (a + b) content (Ct) of 3-year-old Machilus pauhoi and M. leptophylla seedlings were measured, and the relationships of SPAD value with Pn and Ct were analyzed. The M.
