自由区是一个国家或地区采取的“境内关外”的制度安排,也是一个国家法律意义上的“例外空间”。迪拜广泛的自由区体系促进了经济的转型发展,被认为是区域和全球自由区发展的典范。迪拜自由区通过法律、金融、税收、移民、监管等制度建设,不断提升其教育国际竞争力和开放程度,使其成为重要的区域性教育枢纽。同时,迪拜建立各具特色的教育自由区,吸引来自全球的高等教育机构,并为本土和国际学生提供与母校同质的多元课程。迪拜自由区教育对外开放的主要优势在于自由区作为“例外空间”为教育发展提供了差别监管的自由环境,完善的规则框架为教育开放提供了有力的制度保障,但其教育开放仍存在商业性与学术性、本地化与国际化等矛盾与挑战。迪拜自由区教育对外开放的经验教训可以为进一步深化中国特色自由贸易港和自由贸易试验区的制度设计、制度开放与制度创新提供启示和借鉴。

作为当今国际社会中不可忽视的一个政府间国际组织,法语国家组织出于促进多边教育文化合作的历史需求,满足独特政治文化格局的社会需求,以及适应可持续发展议程的全球治理需求,积极开展多边教育治理。法语国家组织将教育与培训融入总体战略框架,旨在加强法语国家在国际舞台上的地位和影响,改善多边主义和全球治理,以及推动实现可持续发展。法语国家组织旗舰教育治理项目主要包括以双语教育为原则的小学教育,以改善就业为目标的职业培训和以信息技术为媒介的教师教育。实践表明,法语国家组织以法语文化扩大了治理影响力,以多边主义提升了治理合法性,以非洲国家放大了治理有效性。

目的:三叉神经痛有多种微创介入治疗方式,各种方法的疗效不同,对于首选治疗方案仍有争议。本研究旨在比较原发性三叉神经痛(primary trigeminal neuralgia,PTN)患者首次接受经皮球囊压迫术(percutaneous balloon compression,PBC)介入治疗和射频热凝术(radiofrequency thermocoagulation,RT)治疗后疼痛复发再接受PBC在治疗效果等方面的差异,以期为患者提供更科学、精准的治疗方案。方法:回顾性分析2020年1月至2021年12月广西医科大学第二附属医院疼痛科收治的103例PTN患者的临床资料,其中首次接受PBC治疗的患者49例(PBC组),RT术后疼痛复发接受PBC治疗的患者54例(RT+PBC组)。比较2组患者术前疼痛评分,术中卵圆孔形态、卵圆孔面积、球囊容积、压迫时长,术后第1天(T1)、第7天(T2)、第14天(T3)、1个月(T4)、3个月(T5)、1年(T6)各时间点的疼痛评分及疼痛复发情况等的差异,并分析术后复发情况与疼痛评分的相关性。结果:2组间一般资料、术前疼痛评分、卵圆孔形态、卵圆孔面积、T1~T3疼痛评分的差异均无统计学意义(均P>0.05)。与RT+PBC组比较,PBC组球囊充盈容积较小,T4~T6的疼痛评分较低,疼痛复发例数较少(均P<0.05),疼痛复发情况与T2~T6的疼痛评分均呈正相关(分别r=0.306、0.482、0.831、0.876、0.887,均P<0.01)。结论:PTN患者首次介入治疗建议选择PBC,在治疗效果和疼痛复发情况等方面均优于RT治疗后疼痛复发再选择PBC治疗。

明晰社会-生态因素对旅游目的地生态系统服务时空格局影响,对实现区域旅游高质量发展和生态环境保护具有重要的现实意义。以典型旅游城市黄山市为案例地,剖析了黄山市2000—2020年的产水量、土壤保持、碳固存、生境质量、旅游休闲5类生态系统服务时空演变特征及其社会-生态因子的作用强度,旨在揭示生态系统服务的时空分异与旅游目的地经济发展之间的联系。结果表明:(1)时间序列上,2000—2020年黄山市的产水量均值先增长后下降,土壤保持服务呈上升趋势,碳固存、生境质量和旅游休闲3项生态系统服务呈下降趋势;(2)空间分布上,产水和土壤保持服务的高值区分布在黄山山脉和南部低山丘陵处,低值区广泛分布在中部和北部;碳固存、生境质量和旅游休闲服务除黄山风景区、黔县和新安江河谷盆地的数值较低外,其余区域高值区集聚明显。5类生态系统服务冷热点空间分布差异明显,但整体有重叠性。(3)影响因子方面,自然因子影响力最强,经济因子和旅游因子次之。然而,经济因子和旅游因子的影响力在不断提升,自然因子虽仍占主导地位,但解释作用在不断减弱。两两因子交互作用主要表现为非线性增强或者双因子增强的关系,即产生“1+1>2”的效果。(4)驱动机制方面,旅游城镇化系统-土地系统-自然环境系统之间相互博弈又协同发展,共同影响黄山市生态系统服务。本研究为旅游导向型城市生态系统服务与旅游经济发展之间的积极互动提供理论支撑。
