“Science is Everywhere,but No One Knows It”: Assessing the Cultural Distance to Science of Rural South African Publics

ABSTRACT

In science communication, a prerequisite for reaching different parts of a society is to find out how these publics experience and interpret science. Since rural South African publics are perceived to exhibit a large cultural distance to science, the present exploratory study aimed to know in more detail how rural South Africans perceive and understand science in their local and social contexts. Theoretical notions on cultural distance and the methodological approach of segmentation studies were considered. Semi-structured interviews with rural South Africans were carried out in four towns (n?=?52) that differ with respect to having a large scientific installation in their vicinity, or not. Sensitively comparing local and social contexts helped identifying three different publics who differed regarding their perceptions of science; however, the large scientific installations only made a difference in perceptions for those publics who were generally less exposed to and less knowledgeable about science.     

The influence of public transportation on housing values

Transit-oriented development (TOD) is becoming an increasingly common development strategy with potential consequences on property values. This study explores the potential relationship between the proximity to public transportation and housing values. The objective is achieved by performing a hedonic regression using the 2013 American Housing Survey (AHS) sample, which includes 25 metro areas. In 2013, the AHS added a topical supplement addressing public transportation issues which makes understanding public transportation impacts on housing values more feasible. In this study, being located within half a mile of a public transportation stop was a significant factor in explaining housing values for 6 out of 25 metro areas. This research is important to real estate practitioners operating within TODs as proximity to public transportation may significantly influence property values.     

Factors influencing perceptions of aquatic ecosystems

While factors influencing perceptions of drinking water have been well studied, those of aquatic ecosystems have been to lesser extent. We conducted a review to improve awareness of these factors. Environmental factors found to influence public perceptions of aquatic ecosystems were presence/absence of water plants and algae, presence/absence of floating debris, the odor, movement (for flowing waters) and clarity/turbidity of the water, and the type, condition, setting, naturalness, and overall aesthetic appeal of the ecosystem. Sociocultural factors found to influence public perceptions of aquatic ecosystems included age, education, gender, and place-based knowledge. We provide perspectives of how managers can better meet the diverse social demands placed on aquatic ecosystems. The importance and benefits of considering these perspectives may be especially beneficial where significant multi-generational and culturally relevant place-based knowledge exist.     

宿迁市公众环境意识调查研究

采用问卷调查与社会访问相结合的方法,对江苏省宿迁市居民的环境意识进行了调查。统计结果表明宿迁市居民对当地环境处于基本满意阶段,并认为政府对环境保护工作比较重视;宿迁市公众具备了一定的环境保护基础知识．但是环境意识比较低,环境保护行为相对滞后,需要政府加以引导,加强环境宣传教育,提高民众的环境意识。     

条件价值评估法研究居民改善空气质量需求

采用条件价值评估方法,调查了北京市居民改善空气质量的支付意愿,初步分析居民对空气质量这种公共环境物品的需求状况,探讨了影响居民对公共环境物品需求的人口和社会经济因素.研究结果表明,居民的经济状况是影响对公共环境物品需求的重要因素,居民的经济状况比较好则对公共环境物品的需求越高,但是支付意愿与家庭收入弹性<1.随着教育水平的提高,对公共环境物品的需求也增加.另外,性别和健康状况也影响居民对公共环境物品的需求.从政策实施的角度来看,政府必须完善人们对公共环境物品需求偏好的表达机制,才能制定政策实现公共环境物品的有效供给.     

简述环境影响评价中的公众参与

环境影响评价制度是一项重要的环境法律制度,公众参与是环境影响评价程序的关键。其目的是使项目能被公众认可,提高项目的环境和经济效益。我国的《环境影响评价法》对公众参与的主体、对象、范围、方式所做的规定还不能令人满意。借鉴西方国家和港台地区立法的先进经验,我们应当通过使法律具有可操作性、协调好国家干预和公众参与、赋予公众提起环境诉讼的权利、加强公众宣传、保证信息透明等方式对其加以完善。     

2019年扬州市公共场所健康危害因素监测结果分析

为了提升扬州市公共场所卫生状况和传染病防控能力,按照国家标准于2019年对扬州市宾馆(酒店)类、沐浴类、理发店类、美容店类和候车室类5类公共场所的健康危害因素(空气质量和公共用品用具)进行监测,按照《公共场所卫生指标及限值要求》(GB 37488—2019)进行评价。结果表明,共监测空气质量样品216份,合格率为84.26%,共监测公共用品用具1 414份,合格率为96.46%,不同场所的空气质量合格率和公共用品用具微生物指标合格率差异均具有统计学意义(P 0.05)。不同类型公共用品用具监测项目中,金黄色葡萄球菌的合格率最高(100%),而真菌总数的合格率最低(93.75%)。各类公共用品用具中,拖鞋合格率最低(91.67%),床单相对较高(99.70%)。扬州市公共卫生状况总体良好,在空气质量监测中,物理项目和微生物项目合格率较低,在公共用品用具监测中,细菌总数和大肠菌群存在不合格现象。     

A human-centered framework for innovation in conservation incentive programs

The promise of environmental conservation incentive programs that provide direct payments in exchange for conservation outcomes is that they enhance the value of engaging in stewardship behaviors. An insidious but important concern is that a narrow focus on optimizing payment levels can ultimately suppress program participation and subvert participants’ internal motivation to engage in long-term conservation behaviors. Increasing participation and engendering stewardship can be achieved by recognizing that participation is not simply a function of the payment; it is a function of the overall structure and administration of the program. Key to creating innovative and more sustainable programs is fitting them within the existing needs and values of target participants. By focusing on empathy for participants, co-designing program approaches, and learning from the rapid prototyping of program concepts, a human-centered approach to conservation incentive program design enhances the propensity for discovery of novel and innovative solutions to pressing conservation issues.     

Molecular tools for bathing water assessment in Europe: Balancing social science research with a rapidly developing environmental science evidence-base

The use of molecular tools, principally qPCR, versus traditional culture-based methods for quantifying microbial parameters (e.g., Fecal Indicator Organisms) in bathing waters generates considerable ongoing debate at the science–policy interface. Advances in science have allowed the development and application of molecular biological methods for rapid (~2 h) quantification of microbial pollution in bathing and recreational waters. In contrast, culture-based methods can take between 18 and 96 h for sample processing. Thus, molecular tools offer an opportunity to provide a more meaningful statement of microbial risk to water-users by providing near-real-time information enabling potentially more informed decision-making with regard to water-based activities. However, complementary studies concerning the potential costs and benefits of adopting rapid methods as a regulatory tool are in short supply. We report on findings from an international Working Group that examined the breadth of social impacts, challenges, and research opportunities associated with the application of molecular tools to bathing water regulations.
