Social science integration at state and federal fish and wildlife organizations in the United States
Conservation Biology, Volume 39, Issue 2, April 2025.Abstract Increasingly, conservation professionals and scholars recognize the need for more holistic integration of social science in fish and wildlife management. This call is often framed around the complexity of 21st century conservation challenges and changing societal values toward fish and wildlife and its management.

Sexuality, Gender &Policy, Volume 7, Issue 3, Page 305-321, August 2024.Abstract The study sought to explore barriers to menstrual education between maternal figures and young girls. Menstruation is a key part of the reproductive process and affects young adolescent girls. Menstrual blood is perceived as contaminating and impure, leading to the socialization of women and girls undergoing menstruation to feel soiled and ...

Design and Implementation of ProductAffective Tendency Analysis System Based on User Comments [PDF]
, 2016 Web2.0时代，用户不仅仅是网络内容的消费者，也同时是互联网内容的生产者。网络上产生了大量的用户评价信息，这些评价信息不仅能给消费者提供对商品的参考，而且能给生产者反馈产品信息，了解自己产品的不足并加以改进。大数据时代人工来做这些工作是不现实的。如何通过使用自然语言处理技术，从大量数据中自动提取出评价对象以及找到用户对某种产品所持有的情感倾向是当前研究的热点。 本文以某电商网站上的某款冰箱产品为研究代表，研究了基于评论信息的评价对象抽取与情感倾向分析技术。本文主要内容和创新点如下： 1 ...

Challenges and opportunities in human dimensions behind cat–wildlife conflict
Conservation Biology, Volume 38, Issue 4, August 2024.Abstract Because global anthropogenic activities cause vast biodiversity loss, human dimensions research is essential to forming management plans applicable to biodiversity conservation outside wilderness areas. Engaging public participation is crucial in this context to achieve social and environmental benefits.

Gaoya dianqi, 2010 以变压器油中溶解气体和变压器故障之间的关系为基础,提出了一种自适应分级多分类支持向量机变压器故障诊断方法。此方法基于模式识别特征提取的思想,采用不同的输入向量,对变压器有无故障和故障类型判别时,采取分级决策结构。采用自适应优化算法对多分类支持向量机进行优化,通过诊断效果和不同类型故障识别率的比较,得出变压器油中溶解气体的组分含量比值更能反映变压器故障类型,最终测试效果比较和支持向量机参数分析,可以看出该方法具有较高的准确率和良好的泛化能力。

Research of Esophagus Disease-aided diagnosis Based on Ultrasonic Endoscope Image [PDF]
, 2015 食管疾病是常见疾病之一，对人们的健康产生了严重的威胁。随着超声内镜(EUS)应用的发展和普及，提高了食管成像清晰度，成为临床诊治的必要诊断工具。超声内镜可为食管疫病的诊断及给出合理的治疗方案给予非常大的帮助，但是国内外对EUS诊断主要依靠内镜医师个人经验，缺乏客观诊断依据，因此使得EUS的应用受到限制。由此看来利用计算机技术对食管疾病进行辅助诊断是非常有意义的。 本文主要研究三类食管EUS图像分类的问题，包括食管早癌、食管平滑肌瘤以及正常食管。首先对EUS图像进行去噪处理，之后提取EUS图像的特征点 ...

Conservation Biology, Volume 38, Issue 3, June 2024.Abstract Multifunctional landscapes that support economic activities and conservation of biological diversity (e.g., cattle ranches with native forest) are becoming increasingly important because small remnants of native forest may comprise the only habitat left for some wildlife species. Understanding the co‐occurrence between wildlife and disturbance
