Drivers of bat researchers’ intent to adopt field hygiene practices

open access: yesConservation Biology, EarlyView.
Abstract Infectious disease is a growing threat to wildlife, with zoonotic transmission most likely at the human–wildlife interface. One underappreciated activity at this interface is fieldwork with wild animals, but associated risks can be mitigated through field hygiene (FH) practices, such as using personal protective equipment and other appropriate

慢性阻塞性肺疾病患者血清IgE含量与支气管舒张试验临床相关性

open access: yesZhongguo shiyan zhenduanxue, 2008
目的探讨慢性阻塞性肺疾病患者血清IgE含量与支气管舒张试验临床相关性。方法取67例COPD患者,血清用散射速率比浊法测定其IgE含量,并进行FEV1及其改善率测定,对所得数据进行统计学分析。结果IgE值与FEV1进行相关性分析和显著性检验呈负相关(r=-0.301 ...

Using customs data to understand overlooked trade in non‐CITES birds between Africa and Asia

open access: yesConservation Biology, EarlyView.
Abstract The international trade in live birds poses risks to animals, people, and biodiversity. To effectively mitigate these risks, decision‐makers require information on the volume, dynamics, and direction of trade. Despite Africa once being the largest exporter of birds by region, very little data exist on recent trade in live birds not listed on ...

Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery

open access: yesConservation Biology, EarlyView.
Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.

三江平原不同类型湿地土壤酶活性及其与营养环境的关系

open access: yesShuitu Baochi Xuebao, 2008
对三江平原3种典型湿地(毛苔草湿地、小叶章湿地、岛状林湿地)的土壤酶活性、土壤养分进行了研究,探讨了不同湿地土壤酶与土壤养分及酶活性间的相关性。结果表明:不同湿地土壤酶活性和土壤养分含量有较大差异。土壤蔗糖酶、脲酶、过氧化氢酶、淀粉酶活性与土壤有机质、全氮、碱解氮含量变化趋势一致,表现为毛苔草湿地>小叶章湿地>岛状林湿地。酸性磷酸酶活性表现为岛状林湿地>毛苔草湿地>小叶章湿地;纤维素酶活性则表现为毛苔草湿地>岛状林湿地>小叶章湿地。经分析,土壤酶活性和养分密切相关,且酶活性间存在一定的相关关系,其中脲酶、

Striking a Balance: Stakeholder Perceptions of Risk in Horse Racing

open access: yesEquine Veterinary Journal, EarlyView.
ABSTRACT Background Thoroughbred racing is a major industry, and in recent years, public concerns about equine safety have become more prominent, particularly in relation to on‐track injuries and fatalities. This has challenged the industry's social licence to operate (SLO).

Integrating Various Types of Feedback in L2 Writing Instruction: Teachers' and Students' Perspectives

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Due to advances in natural language processing and artificial intelligence, automated feedback, teacher feedback, and peer feedback have been available for teachers to utilize in their L2 writing classrooms. Integrating these kinds of feedback in L2 writing instruction remains challenging.

Profiling EFL Students’ Motivation and Anxiety in Collaborative Learning: Associations With Teachers’ Support, Self‐Regulated Learning, and Achievement

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Previous research has established the relationships between motivation, anxiety, teachers’ support, and self‐regulated learning (SRL) in English‐as‐a‐foreign‐language (EFL) learning. Most of the studies, however, have taken a variable‐centered approach in addressing the variable correlations, while learners’ characteristics and variable links ...

不同肥胖指数与胰岛素抵抗的相关性比较

open access: yesZhongguo shiyan zhenduanxue, 2017
目的分析长春地区40岁及以上居民肥胖相关衡量指标与胰岛素抵抗的相关性,选择一种简单、有效的预测胰岛素抵抗的指标。方法共纳入长春地区9273名研究对象,记录性别、年龄及一般情况,测量其身高、体重、腰围以及臀围,并根据测量结果计算体质量指数(BMI)、腰围身高比值、腰围臀围比值,并依据现有诊断标准计算肥胖患病率;同时进行空腹血糖、空腹胰岛素水平测定,计算稳态模型评估的胰岛素抵抗指数(HOMA-IR)、定量胰岛素敏感性检测指数(QUICKI);从而计算肥胖指标与HOMA-IR及QUICKI的相关系数r ...
