中国城市生活垃圾分类回收问题研究——对日本城市垃圾分类经验的借鉴

中国城市的生活垃圾总量呈逐年增长的态势,而目前城市垃圾处理采用的主要方式仍是露天堆放和卫生填埋,这必然要带来垃圾污染、资源浪费和垃圾处理场地紧张等问题.垃圾分类回收是解决上述问题的最好出路.中国的垃圾分类回收难以实施的症结主要表现在观念滞后、理论研究缺乏和政府的工作力度不够.日本具有很好的城市垃圾分类回收的经验,即国家政府重视、地方政府统计数据完备、有切实可行的削减目标以及对居民进行系统而细致的教育等,很值得借鉴.     

对散手运动员疲劳产生机制及其恢复手段的探讨

进入21世纪以来,散手比赛中运动员技术水平和竞技能力日益提高,其运动特点决定了要对运动员进行高强度、高密度的训练。这就难免在运动和训练过程中出现疲劳,必将对系统训练和运动寿命等造成影响,怎样恢复便成为了一个重要的问题,本文针对散手运动员疲劳产生的原因,提出了疲劳恢复的方法和手段。

服务补救悖论是否有效，是否能够被实际运用一直是服务营销的一个争论内容。只有在清晰的界定其内涵，分析和评价了服务补救悖论的有效性和道德性以后，才能指明实施服务补救悖论的条件、程序和注意事项，从而澄清在此问题上的理论分歧和企业面临的实际困惑，有助于服务类企业更好地实施服务补救悖论以提升顾客满意度。     

印刷车间再热的热回收节能策略

针对夏季印刷车间空气处理过程中,由于控制室内温湿度波动而采取再热措施造成冷热抵消的能源浪费现象, 根据空气处理过程焓湿图分析了西安某印刷车间夏季空气处理产生再热的原因,并在对印刷产生有机废气采用局部排 风进行有效收集处理的基础上,针对性地提出了利用热回收以补偿再热负荷的思路。比较了几种常见热回收装置的特 点,根据对印刷有机废气催化处理后排放尾气的温度,选择了热管式显热回收方式,进而分析了其传热量及显热回收效 率的计算过程,突出了其节能优势,最终达到充分利用废热节能的目的。     

The study of mental distress and the (re)construction of identities in men and women with experience of long-term mental distress

This article explores the possibility of using a theoretical framework drawn from disability studies in the field of mental health, and the study of identity (re)construction in the recovery process. In this PhD project, 33 narratives were analysed using framework analysis. The analysis showed that disablism was present and powerful in the participants’ lives, and also showed how disablism shaped how the participants thought and felt about themselves. As Carol Thomas argues, when analysing disablism one should also focus on who we are and are prevented from being, as disabled people. The conclusion is that processes of oppression were central when it comes to understanding the (re)construction of identities. A disability studies perspective is thus relevant in the field of mental distress, and can be used to enhance the understanding of the process of identity (re)construction.     

Construction of Simultaneous Confidence Intervals for Ratios of Means of Lognormal Distributions

For constructing simultaneous confidence intervals for ratios of means for lognormal distributions, two approaches using a two-step method of variance estimates recovery are proposed. The first approach proposes fiducial generalized confidence intervals (FGCIs) in the first step followed by the method of variance estimates recovery (MOVER) in the second step (FGCIs–MOVER). The second approach uses MOVER in the first and second steps (MOVER–MOVER). Performance of proposed approaches is compared with simultaneous fiducial generalized confidence intervals (SFGCIs). Monte Carlo simulation is used to evaluate the performance of these approaches in terms of coverage probability, average interval width, and time consumption.     

Disaster Management from a POM Perspective: Mapping a New Domain

We have reviewed disaster management research papers published in major operations management, management science, operations research, supply chain management and transportation/logistics journals. In reviewing these studies, our objective is to assess and present the macro level “architectural blue print” of disaster management research with the hope that it will attract new researchers and motivate established researchers to contribute to this important field. The secondary objective is to bring this disaster research to the attention of disaster administrators so that disasters are managed more efficiently and more effectively. We have mapped the disaster management research on the following five attributes of a disaster: (1) Disaster Management Function (decision‐making process, prevention and mitigation, evacuation, humanitarian logistics, casualty management, and recovery and restoration), (2) Time of Disaster (before, during and after), (3) Type of Disaster (accidents, earthquakes, floods, hurricanes, landslides, terrorism and wildfires etc.), (4) Data Type (Field and Archival data, Real data and Hypothetical data), and (5) Data Analysis Technique (bidding models, decision analysis, expert systems, fuzzy system analysis, game theory, heuristics, mathematical programming, network flow models, queueing theory, simulation and statistical analysis). We have done cross tabulations of data among these five parameters to gain greater insights into disaster research. Recommendations for future research are provided.     

国民经济恢复时期城乡关系的变化及影响

改变对立的城乡关系,减少城乡差别,是中国共产党成立以来一直奋斗并为之努力去实现的一个重要目标。国民经济恢复时期中国共产党采取了若干措施来缩小城乡差距,推动城乡关系的改变,主要有废除生产资料私有制和剥削制度,城乡居民政治权力的平等化,重视农业的基础性地位,以城市为中心领导和带动乡村发展,慎重处理城乡关系中最为突出的“剪刀差”问题,大力发展城乡文化教育等。在中共和各级政府的领导下,经过全民共同努力,一种新型的、与以前相较而言较为协调的城乡关系渐渐形成,在政治、经济、精神文化等方面出现了新的特点。在肯定国民经济恢复时期中国共产党为构建新型城乡关系所做的种种努力的同时,还需要看到这种努力所带来的变化存在的不足,以及所带来的长期负面影响,故不宜将其无限拔高,应作辩证的分析和客观的评价。     

After the accident: Survivors' perceptions of recovery following road trauma

Road accidents affect thousands of lives each year in Australia. This article discusses findings from three years of research into survivors of major road trauma. The research aimed to examine how survivors of road trauma understood their own experiences of recovery, after sustaining serious orthopaedic injuries and undergoing rehabilitation at a Victorian rehabilitation centre. Seventy-nine respondents completed a self-administered survey and 24 of these respondents then participated in in-depth telephone interviews. Using an ecological framework, the research focused on psychosocial and subjective factors in recovery. The qualitative aspects of recovery are presented - the analysis of perceptions of trauma, recovery, recovery resources and coping in the future. Four main themes of recovery are identified - finding a new fit, the privacy of suffering, anticipatory coping and survivor pride. These themes highlight the complexity of the recovery process.
