Factors influencing the quality of rural human settlements in a peripheral metropolitan area based on a structural equation model: A case study from Beijing

Rural human settlement is a significant indicator of the living standards of rural residents, and its improvement can contribute to promoting the positive interaction between inhabited environment and the social, economic, and resource environment in the countryside. Based on 557 valid questionnaires of satisfaction evaluation of human settlement in the peripheral metropolitan area of Beijing, this paper analyzed the elemental characteristics and factors influencing human settlement quality using multivariate statistical analysis and a structural equation model. The result shows that, first, the rural residents in a peripheral metropolitan area of Beijing are generally satisfied with the quality of human settlement (satisfaction rate is 66.2%). Specifically, the natural and social environment of the countryside is excellent and harmonious and corresponding standard of countryside infrastructure is advanced, but the quality of public services and follow-up management of facilities are in urgent need of improvement and the imbalance between revenue and expenditure of rural households has led to a continuous increase in the pressures of life. Second, factors such as social atmosphere, appearance of the village, entertainment, living costs, fundamental public services, and production costs have significant effects on human settlement quality in this peripheral metropolitan area, with social atmosphere as the main one. Living costs and supporting services are the main constraints to improvement in the quality of human settlement.     

Sustainable outsourcing: a practice survey and research opportunities

This paper addresses the issue of the sustainability imperative and its influence on outsourcing practice. The research initially finds that there is currently little or no work that explores sustainable or green outsourcing, other than in an information technology context. This lack of research on sustainable outsourcing practice in the industrial organisation sector led to the development of this research study. This exploratory study used a qualitative survey tool to investigate current industrial practice. Manufacturing managers in 57 organisations formed the survey sample. The data were analysed by comparison and clustering of responses of survey participants. This study contributes five key findings that demonstrate current industrial practice which includes: 32% of respondents state that sustainability is not a factor in their outsourcing decision making and 65% of small- and medium-sized enterprises had never heard of the ‘triple bottom line’ concept. Future research needs are identified and proposed highlighting that urgent development of research is required in outsourcing performance measurement and also in considering sustainability as a new manufacturing competitive priority.     

大型商业建筑室内步行街商铺火灾荷载调查研究

以我国不同城市的5家大型商业建筑为调查对象,通过现场调查及数据统计分析等方法,对其室内步行街两侧329家商铺的火灾荷载进行调查研究。对不同经营业态商铺数量在所调查商铺总数中所占比例及其地面面积进行了统计,并且获得了商铺内部可燃物种类、数量、质量、分布等情况。按照不同的经营业态,对所调查店铺的火灾荷载密度进行了统计和计算,得出了3种不同分位值的火灾荷载密度,并比较分析了不同经营业态店铺的火灾荷载密度,为大型商业建筑火灾危险性分析及火灾场景设定提供了基础数据。     

基于游客满意度提高乡村旅游经济效益的研究——以威海市河口胶东渔村为例

实现顾客满意是提高企业经营质量管理的重要手段之一,作者将其应用于乡村旅游业经济效益的研究.该研究在形成乡村旅游业游客满意度量表的基础上,加入游客花费的统计指标,使用多元回归分析技术发现游客满意与旅游花费之间统计上呈显著的负相关关系,使用逻辑斯谛回归来进行游客推荐、重游意愿两个二分变量的影响因素的研究,发现游客推荐及重游意愿均受游客花费影响,同时重游意愿还受到游客性别、年龄、收入因素的影响.     

A field experiment characterizing variable detection rates during plant surveys

Surveys aimed at finding threatened and invasive species can be challenging due to individual rarity and low and variable individual detection rates. Detection rate in plant surveys typically varies due to differences among observers, among the individual plants being surveyed (targets), and across background environments. Interactions among these 3 components may occur but are rarely estimated due to limited replication and control during data collection. We conducted an experiment to investigate sources of variation in detection of 2 Pilosella species that are invasive and sparsely distributed in the Alpine National Park, Australia. These species are superficially similar in appearance to other yellow-flowered plants occurring in this landscape. We controlled the presence and color of flowers on target Pilosella plants and controlled their placement in plots, which were selected for their variation in cover of non-target yellow flowers and dominant vegetation type. Observers mimicked Pilosella surveys in the plots and reported 1 categorical and 4 quantitative indicators of their survey experience level. We applied survival analysis to detection data to model the influence of both controlled and uncontrolled variables on detection rate. Orange- and yellow-flowering Pilosella in grass- and heath-dominated vegetation were detected at a higher rate than nonflowering Pilosella. However, this detection gain diminished as the cover of other co-occurring yellow-flowering species increased. Recent experience with Pilosella surveys improved detection rate. Detection experiments are a direct and accessible means of understanding detection processes and interpreting survey data for threatened and invasive species. Our detection findings have been used for survey planning and can inform progress toward eradication. Interaction of target and background characteristics determined detection rate, which enhanced predictions in the Pilosella eradication program and demonstrated the difficulty of transferring detection findings into untested environments.     

濮阳市工业污染特征与产业布局调整路径探析

基于2017年濮阳市第二次全国污染源普查数据,采用聚类分析和核密度分析的方法对濮阳市行业结构特征、工业污染集聚特征进行了分析。结果表明,濮阳市支柱行业为石化行业,工业总产值占比36.92%,远高于其他行业;非金属矿物制品企业数量最多,污染物排放总量最高;颗粒物排放量占濮阳市工业污染源排放总量的33%,占比最高;非金属矿物制品业与石油、煤炭及其他燃料加工业是濮阳市废气污染物的主要来源,石油、煤炭及其他燃料加工业与农副产品加工业是濮阳市废水污染物的主要来源;濮阳市产业集聚区是污染物产排的重要区域,其污染物产生量占濮阳市污染物产生总量的95.49%,污染物排放量占濮阳市排放总量的63.05%。而非产业集聚区的污染物排放量占濮阳市排放总量的36.95%,是精准治污的重点。针对濮阳市产业结构和产业布局现状,提出,重新整合辖区非金属矿物制品业,继续做强石化行业,兼顾发展污染物排放强度低的行业;挖掘产业集聚区减排潜力,建设绿色产业集聚区是经济与环境协调发展的重要途径;非产业集聚区企业应因地制宜,政策引导,发挥中小企业自主能动性,提升环境质量。以期为濮阳市产业布局调整提供技术支持。
