Investigating innovation diffusion,social influence,and personal inner forces to understand people's participation in online e-waste recycling

By integrating the elaboration likelihood model (ELM), innovation diffusion theory (IDT) and social cognition theory (SCT), this study constructs a research model through which to explore the key factors and their influence mechanisms to understand people's participation in online e-waste recycling. Based on the ELM, we believe that people's behavioral intention to participate in online e-waste recycling is affected by the information processing of central and peripheral routes. Based on IDT, we take the perceived innovation characteristics as the key elements of the central route and consider social influence as the key element of the peripheral route. At the same time, we consider personal inner force factors, based on SCT, as the functional condition of the information processing mode to explore the moderating effects of privacy concern, pricing fairness concern, and environmental concern on the information processing of the central and peripheral routes. By taking discarded mobile phones as an example, we collect 475 valid samples to test our research model using the structural equation modelling (SEM) approach. The results confirm that perceived innovation characteristics and social influence are two factors that motivate people to participate in online e-waste recycling and that the three kinds of inner forces have different moderating effects on perceived innovation characteristics and social influence. Based on the above findings, this study puts forward some policy proposals.     

Solid waste management in Mexico’s offshore platform construction: determining potential supply for a reverse logistics process

One of the UN Millennium Development Goals (MDG’s) is to ensure environmental sustainability. This has led international agencies to regulate the generation of waste, specifically solid waste, which is an issue of international significance. This research is an analytical, statistical, historical and deductive investigation that focuses on the management of municipal solid waste and special handling waste (SHW), specifically, the one generated in the construction of offshore platforms in Mexico. A comparative analysis of the waste generated domestically and in the construction of offshore platforms is done. This work proposes the introduction of a third party operator that, through reverse logistics, would develop strategies to recover, reuse or recycle SHW. The level of compliance of the Waste Management Plans of platform construction companies in Mexico is also analyzed. Currently, nine construction companies distributed in the states of Tabasco, Tamaulipas and Veracruz are building offshore platforms in Mexico. Particularly, the south zone of Tamaulipas has become, since the seventies, the largest provider of offshore platforms. These companies are required by law to report the amount of municipal solid waste and SHW that they generate. However, when analyzing the data provided, results show a great area of opportunity. With a proper management of waste, its recovery and/or disposal would be much more efficient. Data collected in the yards of construction is presented, as well as the current situation of the waste in the offshore platform construction industry and possible methods to strengthen environmental policy in solid waste in Mexico.     

经济发展与环境治理的跷跷板：官员竞争博弈下的策略变化

经济发展和环境治理是关系社会福利水平的两个重要指标，但具体到地方官员施政中，不同的官员有不同的策略安排。文章首先基于博弈模型构建了一个官员竞争博弈场景，通过逻辑推导，证明官员在竞争博弈中的相对优劣状态差异是导致官员策略差异的原因。其次，运用倾向得分匹配方法实证检验官员策略差异对辖区“经济福利”和“环境福利”的影响。回归结果发现，官员年龄差对环境治理会有不同影响;低于平均年龄的官员在FDI、税收、固定资产投资等“经济福利”指标上显著高于同级官员2.59万元、0.13万元和0.41万元；而高于平均年龄的官员比同级同行在“环境福利”上有更优秀的表现，在固体废弃物、废气、废水等指标上显著低于同级官员的52吨、21吨和6吨。作为弥补，较年轻官员会采取“踩跷跷板”策略，在一些显性环境治理指标上“适度有为”，例如提高环保投入占比，以回应中央及公众的关切。从理论分析和实证结果中得到的政策启示是在干部晋升考核体系中应进一步突出“绿色发展”的重要性并强化官员的全局意识，激励官员关注辖区非经济福利。

适用于宽带网络波形的基于定价策略的时隙选择

针对宽带网络波形（Wideband Networking Waveform,WNW）的多信道二维时频资源,以减小网络资源浪费为优化目标,提出了一种基于定价策略的时隙选择方法（Pricing Strategy Based Slot Selection,PSSS）。该方法通过接纳控制保障资源分配的公平性,采用对偶优化建模与椭圆搜索法实现最优的时隙选择。理论分析证明该方法能够在多项式级别时间复杂度内搜索到时隙选择的最优解。仿真结果表明,提出的PSSS算法通过较低资源浪费获得了较低的容量冗余度,能够有效地解决WNW多信道网络的时隙选择问题。

Food safety knowledge and practices of consumers in the U.S.A.

Use of safe food handling practices in the home could reduce the number of foodborne illnesses. The objective of this project was to obtain baseline data on the safe food handling knowledge and practices of consumers to aid in the development of effective educational programmes. A food handling questionnaire was developed and completed by 426 Nebraskan respondents. Knowledge and practice questions were based on the most important contributory factors in reported foodborne illness outbreaks. Knowledge scores (correct responses) ranged from 2 to 29 with a mean of 20 ± 4. When compared with the knowledge score, the respondents' education level, where they lived and their sex were statistically significant. Almost all (96%) of the respondents stated that they practised safe food handling when persons were infected. Approximately half of the respondents indicated that they practised safe food handling when handling contaminated raw foods and using foods from unsafe sources. About 45% of the respondents inappropriately left foods at room temperature. One-third of the survey respondents improperly held hot foods. Cross-contamination was a concept understood by 75% of the respondents. Results indicate that food safety education should be targeted on specific groups who are less knowledgeable about safe food handling practices. Results also indicate that a number of respondents knew proper food handling concepts but did not put those concepts into practice. Therefore, increasing the adoption of safe food handling practices by consumers should become an important aspect for educators in food safety educational programmes.
