为探究大学生寝室用电安全意识的现状及分析性别和年级两个变量对其的影响,本文采用问卷调查的方法对大学生进行调查。调查步骤分为预试问卷编制、预试、问卷可靠度分析、正式问卷确定和正式调查。利用SPSS24.0软件对调查结果进行独立样本t检验、单因子独立样本变异数分析(ANOVA分析)等操作,使分析结果更加科学和准确。最终得出结论:大学生寝室用电安全意识在安全认知知识方面较为深刻,在安全认知体验方面有一定的察觉能力,在安全认知监测方面还急需加强学习。另外,性别因素对安全意识有一定影响,年级因素对安全意识没有显著影响。并根据以上结论提出提了高大学生用电安全意识的对策。  相似文献

以对氨基苯磺酸为重氮组分,α-萘胺为显色剂,采用便携式分光光度计,建立了环境水体中亚硝酸盐氮的现场快速测定方法,并将其用于玛纳斯河流域地下水污染调查评价。结果表明:亚硝酸盐氮在0.010~0.200 mg/L时有良好的线性关系,方法检出限为0.003 mg/L,加标回收率(n=5)为90.0%~104.0%,相对标准偏差为0.54%~1.27%,测定结果能够准确反映不同位置环境水体中亚硝酸盐的污染程度。该方法测试成本低,操作简便、快捷,尤其适用于地表水及地下水水质污染调查评价及污染事故的应急监测分析等领域。  相似文献

In this study, we examine aspects of community values and perspectives on goods and services received from the river along with issues related to sustainable management of the river. The study reveals that the contemporary values placed on rivers by communities are mostly associated with recreational and leisure activities. The distance from the river and age of the participants appeared as the most influential social demographic factors affecting participants' perspectives on river health. The study indicates that people tend to develop a strong bond with the natural resources around them and the amount of time spent at a location is directly related to the strength of this relationship. To assess the general river condition and health, a number of visual indicators (e.g., floating debris) were suggested. If properly standardised and calibrated, such indicators have the potential to develop cost-effective monitoring tools for detecting seasonal and spatial changes in river health.  相似文献

The present study employed a quantitative survey to ascertain whether the external pressure of environmental risk management (ERM) on commercial banks was a contributing factor to their ERM behavior. Data was obtained using questionnaires from 204 branches of commercial banks located in the Yangtze River Delta of China. The relationship between external pressure and behavior was tested using a linear structural relations model through path analysis. The results revealed that external pressure of ERM was significantly and positively related to the behavior and that pressure from governmental regulations was the most important contributing factor in the passive feedback behavior and preventive behavior of commercial banks. The pressure from markets was the most important contributing factor in banks’ active participation behavior; the pressure from community and NGOs was the most important contributing factor in their enthusiastic behavior.  相似文献

ABSTRACT

Limited research to date has qualitatively explored the perceptions members of the public who are not environmental activists hold of environmentalists. Therefore a qualitative survey was conducted with 89 US residents aged 21–53 (Mage?=?32.74, SDage?=?7.89) to obtain an in-depth understanding of how non-activists within the public perceive environmentalists. Data obtained were analyzed using thematic analysis and demonstrated that non-activist perceptions of environmentalists contained both positive and negative components. Environmentalists were seen to value nature and to be actively involved in bringing about positive environmental change (positive component), yet were also viewed as aggressive in their behaviors and stubborn in their beliefs (negative component). Further still, it was found that environmentalists were more likely to be perceived positively when they engaged in individual-level, private sphere behaviors (such as recycling), and negatively when they engaged in collective-level, public sphere behaviors (such as protesting). These findings not only challenge the assumption that members of the public typically evaluate environmentalists negatively, they also outline why some individuals may fail to identify as an environmentalist and engage in pro-environmental behavior. Furthermore, they also provide some insight as to why some environmentalists find it difficult to advocate for system change that results from collective action within the public sphere.  相似文献

Abstract

This paper describes the results from a pesticide residue survey conducted in relation to the 1980 spraying of insecticides in New Brunswick (Canada) to preserve the coniferous forest from an on‐going spruce buciworm infestation. A total of 465 water and air samples were collected from 12 sites throughout the Province.

In water, fenitrothion was usually detected at about the same time that spraying occurred in the immediate area of the sites. The maximum that was ever detected was 2 0.0 ppb and persistence was usually United to a few days except in a small pond where fenitrothion was detected for a total of 18 consecutive days. Aminofenitrothion was also detected at a maximum of 8.0 ppb.

Fenitrothion was only detected occasionally in air samples the maximum being 1.2 ng/dm3. However, aminofenitrothion was present in several air samples at c. maximum of 12.0 ng/dm 3.  相似文献

Global demand for elephant ivory is contributing to illegal poaching and significant decline of African elephant (Loxondonta africana) populations. To help mitigate decline, countries with legal domestic ivory markets were recommended by the Convention on International Trade in Endangered Species of Wild Fauna and Flora to close domestic markets for commercial trade. However, implementing stricter regulations on wildlife trade does not necessarily mean compliance with rules will follow. Using an online questionnaire, we examined the relationship between self-reported compliance with ivory trade regulations among 115 ivory traders in the United Kingdom and 4 dimensions (control, deterrence, legitimacy, and social norms) hypothesized to influence compliance with conservation regulations. Although most traders supported regulations, a large number did not always check that they comply with them when trading objects containing ivory. The main factors influencing compliance with ivory trade regulations were traders’ ability to comply and their perceptions of the regulations and punishments to deter illegal trade. These findings demonstrate the utility of conservation criminology to improve wildlife trade regulations and identify opportunities to reduce illegal ivory entering the market in the United Kingdom. Compliance could be improved by clearer regulations that facilitate easier detection of illegal ivory products and stronger prosecution of violations.  相似文献

Istanbul is one of the world's cities most vulnerable to seismic events. According to seismologists, the probability of a severe earthquake in the next 30 years is approximately 40 per cent. Following an outline of the seismicity of this vital Turkish city and a summary of current seismic risks and mitigation studies, this paper presents the results of a survey conducted in two districts of Istanbul, Avcilar and Bakirkoy. The survey comprised some 60 questions on the seismic risk perceptions of individuals and requested basic personal data, such as on age, education level, employment type, financial income, and gender. Despite various differences among the survey population, such as academic background and level of financial income, responses were surprisingly similar, especially in terms of having no plan for a safer house. The data may help those planning mitigation programmes and public awareness campaigns on preparedness and particularly mitigation in highly vulnerable regions.  相似文献

In this paper, we construct a model in which the impact of pollution on health is exerted through both direct and indirect channels. The indirect channel is captured by a production function in which the principal health-improving factor, income growth, can be realized only in the cost of pollution increase. This model is then tested by the aggregated chronicle disease data in over 78 Chinese counties. Our results show, after attaining the threshold of 8 μ g/m^2, continuous increase in industrial SO2 emission density will lead the ratio of population suffering chronicle diseases, among which respiratory diseases occupy a significant proportion, to rise. However, owing to technological progress in pollution control activities, the needed SO2 emission to produce one unit of GDP diminishes with time. Therefore, the negative effect from pollution augmentation on public health seems to be recompensed more and more by the positive effect of economic growth.  相似文献
