考虑次固结的吹填土单桩负摩阻力计算研究

本研究主要目的在于提供一种考虑场地吹填土次固结时变效应的吹填土单桩桩侧桩侧负摩阻力计算方法,该方法通过对场地吹填土进行一维场地吹填土次固结试验,获得孔隙比-时间对数(e-lgt)曲线,利用曲线拟合获得场地吹填土次固结系数及相应计算参数,计算任意时刻的场地吹填土次固结时变沉降量,获得桩侧桩侧负摩阻力中性点位置,并进一步计算得到总的桩侧桩侧负摩阻力。该研究成果可为快速成陆的吹填场地基桩工程设计和施工提供参考。

危险废物刚性填埋场设计造价初析

2019年9月30日,《危险废物填埋污染控制标准》(GB 18598—2019)颁布.新标准中明确提出了刚性填埋场的适用范围,补充了旧标准中对原柔性填埋场未能约定的固体废物的处置手段.文章以广东某拟建的刚性填埋场为案例,在其结构规划过程中对不同设计高度下的危险废物填埋场的主体结构造价成本进行了分析.通过对同条件下不同高...     

Consumer engagement with brands on social network sites: A cross-cultural comparison of China and the USA

To advance theoretical understanding of consumer engagement on social media, this cross-cultural study evaluates how culture influences consumers’ engagement levels and activities on brand pages of social network sites. It further evaluates the underlying motivations and engagement mechanisms in two culturally distinct countries, China and the USA. Specifically, social media dependency, parasocial interaction, and community identification are examined as the key antecedents of consumer-brand engagement. The results confirm the effects of the proposed antecedents and reveal both cultural differences and similarities between Chinese and American consumers’ engagement with brand pages on social network sites.

Managing solid waste in small hotels

Collectively, small hotels constitute a significant solid waste management (SWM) problem. Little research has focused on the SWM practices of small hotels. In the United Kingdom, much of the solid waste generated by small hotels goes to landfill. This study uses a constructionist approach to investigate SWM issues in small hotels in a local authority in Wales and examines the role of the public sector in helping small hotels manage their solid waste effectively. The results revealed that only a minority of small hotels were considering the adoption of sustainable SWM practices, either because hoteliers felt negatively about sustainable SWM alternatives or perceived challenges – an issue which necessitates government intervention. At the time of this study, the public sector provided only very modest services to enhance SWM practices. This study proposes a best practice model for the public sector to encourage small hotels to manage their solid waste effectively, in order to reduce or even eliminate waste for landfill. Local authorities' support is required to make waste management hierarchy options more accessible to small hotels and should incentivise better waste management through increasing the gap between the costs of landfill and recycling waste.     

World Heritage Site: an effective brand for an archeological site?

This study examines whether branding archeological sites as World Heritage Sites (WHSs) will affect potential demand patterns. The study's research objectives are (1) to explore awareness of potential visitors to the brand and logo of WHS; (2) to investigate the effects of the designation on tourists' future behaviors; (3) to clarify whether the number of sites designated (3 versus 10) has an effect on future visitation patterns; and (4) to reveal possible relationships between the perception of a site as part of the world heritage and UNESCO's designation. This study commenced with an exploratory stage followed by administration of structured questionnaires focusing on inbound tourists to Caesarea, an archeological historical site in Israel. The findings indicate only moderate visitor awareness of the WHS title and logo, implying low brand equity as well as insignificant effects on future demand patterns. Moreover, visitors' willingness to pay (WTP) as well as overall motivation to visit seems to decline following the designation. However, visitors' perception of the site as world heritage is positively linked to WTP. The number of designated sites within a particular state is found to have a positive effect on future demand patterns. Based on the findings specific recommendations are offered.
