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.     

酸性蚀刻废液中铜的形态分布及电化学行为

在氯化物体系中，Cu^＋、Cu^2＋均能与Cl^-形成多种形态的配合物，存在形态及分布与溶液中各离子浓度有关。由于各种配合物的稳定性不同，致使Cu^＋、Cu^2＋氯化物的溶解度及电极电位也不同。对酸性蚀刻废液中铜的存在形态、电化学行为、以及采用隔膜电解法回收工艺的可行性进行了分析。

Optimal Size in the Waste Collection Sector

The purpose of this study is to analyze the cost structure of a sample of Italian wastecollection firms in order to assess economies of scale and density and, therefore, definethe optimal size of the firms. A total and a variable translog cost function were estimated using panel data for a sample of 30 firms operating at the provincial level over the period 1991–1995.The empirical evidence suggests that franchised monopoly, rather than side-by-sidecompetition, is the most efficient form of production organization in the waste collection industry. Further, the majority of firms are not operating at optimal scale.     

论死刑的存废与中国死刑制度的现实选择

死刑制度的存废与死刑制度的取向一直是中国理论与立法界争论的热点问题之一,中国现行的死刑制度的存在有其一定的合理性,但在限制和废除死刑的国际趋势下,中国在刑事立法上是否也应该全面废除死刑制度。本文以此为视角,对这一问题进行粗浅的探讨。

Web content mining for comparing corporate and third‐party online reporting: a case study on solid waste management

This study investigates the coverage of solid waste management on 1142 websites maintained by companies, news media and non‐governmental organizations to validate an automated approach to content and language analysis. First, a frequency analysis of waste management terms sheds light on the breadth and depth of their environmental discourses, revealing that corporate and media attention to waste management is small compared with that of non‐governmental organizations. Second, an investigation of their attitudes toward waste management suggests that companies avoid negative information in environmental communication, unlike news media or non‐governmental organizations. Ultimately, an automated tool for ontology building is employed to gain insights into companies' shared understanding of waste management. The ontology obtained indicates that companies conceptualize waste management as a business process rather than framing it from an ecological perspective, which is in line with findings from previous research.
