Fundamental insights on when social network data are most critical for conservation planning
Conservation Biology, Volume 34, Issue 6, Page 1463-1472, December 2020., 2020 Abstract As declines in biodiversity accelerate, there is an urgent imperative to ensure that every dollar spent on conservation counts toward species protection. Systematic conservation planning is a widely used approach to achieve this, but there is growing concern that it must better integrate the human social dimensions of conservation to be ...

An Improved Method of Intravenous Infusion Exhaust Specialized in Operating Room During Anesthesia [PDF]
与普通病房静脉输液排气操作比较，手术室麻醉期间静脉输液准备具有特殊性，主要表现在手术室使用管径较粗的输血器代替普通输液器，使用三通阀代替管径很细的头皮针。前者是便于术中必要时快速输液/输血，后者是便于麻醉医生追加药物。另外，手术室麻醉期间的静脉输液操作比较频繁、时间相对紧迫、排气必须成功。鉴于手术室麻醉期间静脉输液准备的特殊性，笔者设计出一套改进的静脉输液排气方法。该方法巧妙地运用流体力学原理，恰当地融入美学元素，将手术室麻醉期间静脉输液排气操作表现得美仑美奂。在保证排气成功的前提下，该方法操作时间短 ...

On Japanese Legal Protection on Product Configuration and Relevant Reference [PDF]
, 2016 商品形态可以理解为以商品形状为基础，结合商品图案或颜色所形成的整体外观。商品形态的保护可以分为两个层次：作为商业标识时应受到免于混淆的保护；作为智力成果时对于酷似性模仿商品的交易行为的规制。商品形态的模仿，也就可以分为混淆商品来源的模仿与不正当利用他人智力成果的模仿。这两种模仿行为本质上都是利用他人商业成就而未付出实质性努力的行为，即俗称“搭便车”的不正当竞争行为。我国现行法律没有明确“商品形态”的法律概念，对于商品形态的前述两个层次的保护是不完善的。本文将在介绍日本《不正竞争防止法 ...
