Pro-Environmental Civic Participation in the USA: The Effects of Social Media, Pro-Environmental Lifestyle and Climate Experiences

This study addresses the link between social media use and pro-environmental civic participation considering the moderating effect of social media affordances (public realm) on one hand, and lifestyle behaviors and climate change experiences (personal realm) on the other. We combine communication theory and behavioral models and using a sample of USA individuals (N = 7225) based on the American Trends Panel to predict variations in pro-environmental behavior. We show that social networks rather than information are more effective in predicting pro-environmental behavior. Moreover, a pro-environmental lifestyle as well as climate change experiences at the community level increase the likelihood for pro-environmental participation. However, affordances related to socioeconomic variations generate variations to pro-environmental civic participation. We conclude that in order to capture the depth of pro-environmental civic participation, it is necessary to theoretically and empirically bridge between private and public expressions of pro-environmental awareness.

Study on Robust H_∞ Filtering in Networked Environments

This paper is concerned with the robust H ∞ filter problem for networked environments, which are subject to both transmission delay and packet dropouts randomly. By employing random series which have Bernoulli distributions taking value of 0 or 1, the data transmission model is obtained. Based on state augmentation and stochastic theory, the sufficient condition for robust stability with H ∞ constraints is derived for the filtering error system. The robust filter is designed in terms of feasibility of one certain linear matrix inequality （LMI）, which is formed by adopting matrix congruence transformations. A numerical example is given to show the effectiveness of the proposed filtering method.

Comparative Analysis of Different Sampling Rates on Environmental Sound Classification Using the Urbansound8k Dataset

Environmental sound classification (ESC) has gained increasing attention in recent years. This study focuses on the evaluation of the popular public dataset Urbansound8k (Us8k) at different sampling rates using hand crafted features. The Us8k dataset contains environment sounds recorded at various sampling rates, and previous ESC works have uniformly resampled the dataset. Some previous work converted this data to different sampling rates for various reasons. Some of them chose to convert the rest of the dataset to 44,100, as the majority of the Us8k files were already at that sampling rate. On the other hand, some researchers down sampled the dataset to 8000, as it reduced computational complexity, while others resampled it to 16,000, aiming to achieve a balance between higher classification accuracy and lower computational complexity. In this research, we assessed the performance of ESC tasks using sampling rates of 8000 Hz, 16,000 Hz, and 44,100 Hz by extracting the hand crafted features Mel frequency cepstral coefficient (MFCC), gamma tone cepstral coefficients (GTCC), and Mel Spectrogram (MelSpec). The results indicated that there was no significant difference in the classification accuracy among the three tested sampling rates.

环境产品贸易网络的结构特征及演进机制——基于共建“一带一路”国家的实证

加强环境产品贸易合作是推进区域绿色发展的重要途径。该研究基于社会网络分析视角,利用2000—2020年共建“一带一路”国家的54种环境产品贸易数据构建环境产品贸易网络,采用时间指数随机图模型(TERGM),探究区域环境产品贸易网络结构特征及其演化机制。研究发现:①样本区间内,环境产品贸易网络密度和平均聚类系数总体呈上升趋势,平均路径长度缩减,网络直径较短,但是受疫情影响,2020年网络特征指标数值明显下降。②意大利、中国、韩国和新加坡的点出度与点入度排名位于前列,在贸易网络中发挥“桥梁”与“枢纽”作用。中国后来居上,成为点出度与点入度最高的国家,引领区域环境产品贸易发展。③欧洲与亚洲是环境产品贸易网络中贸易合作最密集的两个地区,非洲、拉丁美洲地区的共建“一带一路”国家具有较少的环境产品贸易关系,且源自板块外进口关系数显著多于出口关系数。④TERGM分析表明,环境产品贸易网络存在显著的互惠性、连通性、稳定性和变异性。工业增加值、经济自由度和绿色创新存在发送效应和接收效应,人均GDP、环境规制存在发送效应。地理距离不利于形成环境产品贸易合作。⑤环境保护型产品、可再生能源产品、环境监测分析与评价设备贸易网络的形成和演化具有异质性。基于该结论,从引领区域绿色低碳发展、因地制宜深化环保产业合作、加快环保产业转型升级等方面,提出了深化和拓展“一带一路”环境产品贸易关系的对策建议。
