Multifunctional fibrous wound dressings for refractory wound healing

Refractory wounds have always been an important issue to healthcare systems, whose healing process is always delayed by multiple factors, including bacterial infections, chronic inflammation, and excessive exudates, etc. Employing multifunctional wound dressings is recognized as an effective strategy to deal with refractory wounds, which has yielded promising outcomes in recent years. Among these advanced wound dressings, fibrous dressings have gained growing attention due to their unique merits. Such wound dressings have demonstrated great potential in delivering theranostic agents, such as antibacterial agents, anti-inflammatory drugs, growth factors, and diagnostic probes, etc., for the purposes of accelerating wound healing. This paper reviews the development of multifunctional fibrous dressings and their applications in treating refractory wounds. The construction approaches of novel fibrous dressing with capabilities of antibacterial, anti-inflammation, exudate management and diagnosis were also introduced. Furthermore, the existing problems and challenges are also discussed briefly.

人才吸引力因素与政策工具契合关系研究以河北省为例

人才是第一资源,人才引进培养是经济社会发展的一个关键,近年来我国各地纷纷出台吸引人才的重磅政策.为探求人才政策工具对人才的吸引力情况,在构建人才吸引力因素理论模型基础上,通过对178位人才问卷调查获得人才吸引力关键因素,对河北省163份人才政策文本进行数据挖掘,分析政策工具与人才吸引力因素的契合关系.研究得出创新氛围、人才培训培养、人才激励评价、创新创业支持、人才服务和薪资待遇等方面契合度高,政策效果较佳;工作场所仪器设备条件、配偶子女安置和住房补贴的契合关系为政策不足,应加大政策制定;人才载体和医疗社会保障的契合关系为政策冗余,需加强政策实施.

共享自动驾驶汽车使用意愿模型及其影响因素

为了构建共享自动驾驶汽车(shared autonomous vehicles，SAV) 的使用意愿模型并分析其影响因素，通过使用时机和使用频率来体现公众对SAV的使用意愿；采用验证性因子分析将态度潜变量转化为潜变量得分，以此将态度潜变量引入传统的有序Logit模型；提出SAV使用意愿的有序Logit模型构建方法，并建立基于个人属性、通勤特征、态度潜变量的SAV使用意愿模型.研究发现:是否使用过滴滴拼车、工作单位停车费、自动驾驶态度对使用时机和3种价格(1，2，3元/km) 下的使用频率有显著影响；使用过滴滴拼车、工作单位收取停车费、支持自动驾驶的群体倾向于频繁地、更早地使用SAV出行；公众期望以1元/km或 2元/km即不超过目前滴滴拼车的价格使用SAV.
