简介:少数民族地区光棍的产生有其独特机制。以黔东南B乡侗寨为考察对象,研究发现,族群认同、高密度亲缘“拉力”与传统婚姻规范共同形塑女性“逆外流化”,既成为强化本地通婚圈的力量,但也造成本地通婚圈内婚姻资源供需错位,婚姻“寻觅”被迫走向全国婚姻市场。悖论在于,在非积累型家计模式下,本地男性的家庭积累能力难以支付全国婚姻市场上的女性“要价”,且男性个体教育水平、社交能力等综合素质条件较差,难以与其他地区的男性竞争。在这种弱竞争力下,少数民族地区男性既无法从全国婚姻市场上获得婚配机会,又难以在本地通婚圈内获得充沛的婚姻资源,其婚配几率受到双重结构挤压,因而光棍产生具有结构必然性。缓解光棍压力及其社会后果,关键在于教育水平提升、破除婚姻禁忌及优化劳动力配置,提升婚姻竞争力。
简介:洛杉矶快艇队本赛季充满了惊奇,他们不但坐稳了西部前四,而且更是以克里斯·保罗与昌西·比卢普斯双控位的组合震惊联盟。保罗、比卢普斯和卡隆·巴特勒的加盟让快艇队的季票瞬间卖空,历史上也第一次在球票销售方面能与同城兄弟湖人队相抗衡。造成这些效应的原因不仅仅是被球迷们戏称为"饱嗝组合"的保罗与布雷克·格里芬的表演,比卢普斯与德安德鲁·乔丹的配合也开辟了另一条火线。许久之前,联盟中就曾有过两名伟大的组织后卫同时上场的情况发生,但也仅仅是个案。今日的快艇绝对是历史上打法最独特的球队之一,两名杰出控卫传球的路线不是在地板上,而是在篮圈上,而两名内线"双塔组合"格里芬与乔丹更是轮番在空中等着,将"空中接力"这一高难动作常态化了。"双控卫组合"加"双塔组合",快艇队的变态打法真够"顶你个肺了"。尽管双控卫从来没有成为NBA中的主流,但此后它一定会对整个篮球领域产生革命性的冲击。
