Place attachment has been a research focus in the fields of park and recreation management. Place attachment plays an important role in promoting sustainable development of parks and mountain tourism destination, however, there are limited studies that identified the spatial patterns of place attachment, especially in the context of mountain tourism destinations in China. Also, the geospatial spectrum of visitors is usually broad, examining the multivariate relationships among spatial proximity, perceived authenticity, and place attachment are essential for mountain tourism destinations to promote destination image and strengthen emotional bonding with targeted visitor groups. In this study, we selected an iconic and highly visited park, Jiuzhai Valley National Park in China, as our study site and conducted an on-site visitor survey to collect 557 samples. Study uses factor analysis and the structure equation model to analyze the relationship among spatial proximity, perceived authenticity, and place attachment. Results validate the two-dimension structure of place attachment and perceived authenticity. Study findings suggest that spatial proximity has significant impacts on existential authenticity and place identity, but has no significant impacts on place dependence. Perceived authenticity has a positive impact on place attachment. Study results advance the theories of place attachment and provide effective strategies to enhance emotional attachment between visitors and mountain tourism destinations.

A palygorskite/carbon composite was prepared through hydrothermal treatment of palygorskite and cellulose, and its adsorption behavior for methylene blue (MB) was investigated. The effect of adsorption conditions on the capacity and kinetics was also investigated. The adsorption kinetics of MB onto the composite is best described by a pseudo-second-order equation. The adsorption isotherms conform to the Langmuir isothermal adsorption equation. The adsorption thermodynamic parameters calculated from the isotherms indicate that the adsorption of MB on the composite is endothermic. [New Carbon Materials 2015, 30(1): 71–78]

Organophilic palygorskite/carbon composites were prepared through a green hydrothermal carbonization process using palygorskite clay and cheap cellulose as raw materials. The effects of reaction temperature (210 °C to 250 °C) and time (2 h to 48 h) on the product structures were investigated, and a potential reaction mechanism was proposed. Nanocarbon particles (10 nm in diameter) were loaded onto the palygorskite surface (220–250 °C, 12 h or 210 °C, 24–48 h). Results from the Fourier transform infrared and X-ray photoelectron spectroscopy showed that the resultant palygorskite/carbon composites contained organic groups, including CH , CH2 , CH CH and C O. The coating mechanisms of palygorskite and nanocarbon were also discussed. The contribution of organic carbon to organophilic improvement was further confirmed by the static adsorption of phenol. The removal rate of phenol from aqueous solution increased with hydrothermal time and temperature, indicating that the loading of nanocarbon particles with organic groups made an important contribution for the organic modification of palygorskite. The palygorskite/carbon obtained at 250 °C in 48 h exhibited the highest adsorption (92 wt.%) of phenol, which was slightly higher than that of commercial active carbon (90 wt.%) and significantly higher than that of unmodified palygorskite (18 wt.%).

Objective To verify the therapeutic methods and clinical efficacy on stump stomach atony after subtotal gastrectomy (SSASG) treated with acupuncture and TDP. Methods Fifty-three cases were divided into an observation group (23 cases) and a control group (30 cases) according to the random number table. In the observation group, acupuncture was applied in combination with TDP. The main acupoints were Zusānl ( ST 36), Pishū ( BL 20), Weishū ( BL 21) and Zhōngwan ( CV 12). The treatment was given once per day. 10 treatments made one session. Two sessions of treatment were required. In the control group, Motilium was prescribed for oral administration, 10 mg each time, three times per day, continuously for 20 days. The changes in the relevant parameters in electrogastrogram (EGG) were observed before and after treatment. The efficacy was assessed. Results The principle frequency and the waveform reaction area of EGG were improved apparently after treatment in both groups (all P Conclusion Acupuncture in combination with TDP can effectively treat SSASG. This therapy apparently improves the gastric motility, tremendously promotes the gastrointestinal peristalsis and recovers the gastrointestinal function after operation. The efficacy of it is superior to that achieved by the oral administration of Motilium.

A novel C-band hole-coupled bandpass filter with metallized post (or via-hole) arrays directly embedded in middle of the microstrip line is presented in this letter.The proposed filter removes via-hole arrays embedded along waveguide section from the half-mode substrate integrated waveguide filter, while the new concept simplifies the structure of previous filter. Simulated and experimental results show that the proposed filter of this paper has good performances of low insertion loss, return loss, and better rejection characteristics. The insertion loss of measured four-pole filter is about 0.8 dB, and the return loss is better than −25 dB in the whole passband. Keeping the advantages of excellent performances, the proposed filter can be constructed more conveniently and is suitable for low-cost planar circuit. © 2011 Wiley Periodicals, Inc.

Carbon nanotubes (CNTs) doped TiO2/glass fiber reinforced plastics (GRP) hybrid materials with different TiO2and CNTs contents were prepared by first step sol-gel and then hand lay-up method, using modified CNTs doped tetrabutyl titanate as precursor. The results showed that high TiO2and CNTs contents obtained GRP with high temperature stability and high electrical conductivity, but slowed down the solidification process of epoxy resin to obtain GRP.

Perovskite-type LaFeO(3) and alpha-Fe(2)O(3) with high specific surface areas were directly prepared with appropriate stearic acid-nitrates ratios by a novel stearic acid solution combustion method. The obtained powders were characterized by XRD, FT-IR and XPS techniques. The catalytic activities of perovskite-type LaFeO(3) and alpha-Fe(2)O(3) for the thermal decomposition of octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) were investigated by TG and TG-EGA techniques. The experimental results show that the catalytic activity of perovskite-type LaFeO(3) was much higher than that of alpha-Fe(2)O(3) because of higher concentration of surface-adsorbed oxygen (O(ad)) and hydroxyl of LaFeO(3). The study points out a potential way to develop new and more active perovskite-type catalysts for the HMX thermal decomposition.

The distribution of social resource is not only affected by social conditions such as economic, political and cultural factors, but also influencing society in return. Three distribution modes: market dominated invisible hand mode, government dominated visible hand mode, and non-governmental organization dominated the third hand mode all have certain kind of drawbacks. In the context of public administration with collaborative governance, market, government, and non-governmental organizations are in different fields, adopting diverse methods to allocate resources. These three parts learn from and impact each other, leading to the best resource exploitation, which realizes the maximization of social public benefit.

Taking the textile industry as an example, with the help of a series of input-output indicator, this paper calculates and analyses the agglomeration trend and regional distribution of the overall Chinese textile industry, conducts the Stewart Granger causality test on the relationship between spatial agglomeration degree and agglomeration profits of the textile industries, and discovers the balanced relationship and bi-directional causality relationship between spatial agglomeration level and agglomeration profits of the whole textile industries. But from the perspective of regional analysis, some areas with higher agglomeration level has the inversion phenomenon that the cost-benefit indicator is lower than the national average, and the trends of excessive agglomeration, production factors' congestion and decreased profits can be proved from more intuitional scatter diagram. Research findings provide theoretical support on how to guide the interregional flow of production factors scientifically, how to achieve industrial gradient shift, how to optimize the resources allocation.
