Validation of the accuracy of household reporting of subsistence fishing catch and effort: a Fijian case study

Abstract  The accuracy of household reporting of subsistence fishing catch and effort and seafood consumption on the Fijian island of Ono-i-Lau was studied. A creel survey was carried out concurrently to validate the household survey data. Reported estimates of fishing participation, effort, and fish consumption were not significantly different to the creel survey estimates. Householder's appeared to overestimate the number of fish from the most abundant family Lethrinidae, and underestimate rarer fish. However, there was no significant difference between the reported and observed contribution of the majority of finfish families and invertebrate taxa. The reported and observed catch rate estimates were not significantly different, indicating that Ono-i-Lau villagers are relatively accurate in their estimation of the number and size of fish from recalled catches.     

不同环境条件下几种高寒草甸植物的非克隆繁殖投入和生长

通过对高寒草甸生态系统金露梅灌丛、矮嵩草草甸、围栏矮嵩草草甸以及模拟地球增温效应下5种植物繁殖投入和生长特性的测定,结果表明,矮嵩草、麻花艽、苔草以及美丽风毛菊的叶长沿对照矮嵩草草甸、0TC、围栏以及金露梅灌丛呈现上升趋势,只是灌丛中苔草和麻花艽两种植物的叶长较围栏和OTC有所下降,而环境变化对植物的叶宽的影响较小。苔草在金露梅灌丛中的繁殖投入最大,其次是矮嵩草草甸和围栏,OTC中苔草的繁殖投入几乎为零。围栏与矮嵩草草甸内苔草的繁殖投入差异不显著,而两者中植物的繁殖投入与金露梅灌丛相比,差异性显著(P<0.05)。矮火绒草在矮嵩草草甸中的繁殖投入最大,其次是0Tc和围栏,灌丛中矮火绒草的繁殖投入最小。OTC与矮嵩草草甸内矮火绒草的繁殖投入差异不显著,而OTC与围栏中矮火绒草的繁殖投入差异性显著(P<0.05)。由此我们可以得出一个结论:繁殖投入随环境梯度的变化,反映了植物繁殖对策和繁殖投入在整个生活史特征中的可塑性。     

Relationships between catch and effort in Fijian multispecies reef fisheries subject to different levels of exploitation

Abstract The catch-per-unit-effort (CPUE) and value-of-catch-per-unit-effort (VPUE) of reef-associated fish species from six Fijian native fishing grounds ( qoliqoli ) subject to different fishing intensities were determined using records of fishing activity from a voluntary logbook scheme. Line and spear fishing techniques were used for more than half the total fishing time (h person^-1 d^-1) in all qoliqoli , and yet the favoured technique in a given qoliqoli was frequently less efficient (lower CPUE) than other techniques. The popularity of relatively ineffective fishing methods implies that fishermen did not always attempt to maximize their catch rates. To compare fishing effort in different qoliqoli , all effort was rescaled on the basis of its recorded efficiency (measured as multispecies CPUE) and expressed as hours equivalent to boat-based spear fishing over coral by day to catch fish for sale. Total fishing intensity in the six qoliqoli ranged from 72 to 4310 h km^-2 reef year^-1. The relationship between catch and effort was linear at all fishing intensities, suggesting that the qoliqoli were all fished on a sustainable basis. Furthermore, whilst there was a significant difference in CPUE and VPUE between the one or two qoliqoli with lowest fishing intensity and all the others, there were no significant differences between these other qoliqoli in terms of the VPUE of the saleable multispecies boat catch or the CPUE of species from piscivorous and carnivorous genera ( Epinephelus, Lethrinus and Plectropomus ) which the fishermen prefer to catch.

依法管理在高校思想政治辅导员工作中的应用

高校思想政治辅导员在学生管理工作中,缺少依法管理的意识和观念,应培养自身的法治意识,在工作中依法管理,加强对学生的法治教育,促进高校学生管理工作法治化、制度化、规范化。     

金融消费者保护问题的框架性思考

金融消费者是为生活消费需要而购买、使用金融商品或接受金融服务的人,具有追求盈利最大化、抗风险能力差以及弱势地位突出等特点。现阶段我国有关金融消费者权益保护方面的工作同发达国家相比还很不完善,存在缺乏专项立法、相关法律滞后、缺乏专业纠纷解决机制以及对金融消费者合法权益保护不到位等问题,急需国家相关部门出台相关政策文件改善和解决。     

论房屋征收与补偿过程中的维权机制

随着现阶段城市建设速度的加快，各地因拆迁行为引发的争议越来越激烈。为了更好地协调城市发展与私人权益的关系，2011年1月21日国务院颁布了《国有土地上房屋征收与补偿条例》（简称《征收条例》，下同）。与先前的《城市房屋拆迁管理条例》相比较，《征收条例》无论在立法的价值目标、具体的实施机制方面都有很大的区别。以《征收条例》和相关立法作为制度框架，构建并逐步完善房屋征收与补偿过程中的维权机制，有助于使得包括《征收条例》在内的上述立法得以贯彻实现，从而使得利益博弈在市场经济、法治国家的轨道上进行。     

美国军事司法禁止强制性自证其罪规则解读

美国军事司法禁止强制性自证其罪规则,与"米兰达规则"有着本质区别。尽管二者在法源上相同,但建立的规则不同。美国军事司法禁止强制性自证其罪规则确立了禁止刑讯逼供原则、预先告知原则和非法证据排除规则,但虐囚事件充分暴露了美国军事司法禁止强制性自证其罪规则的本质。     

对自诉权的理论解构

自诉权源于个体的一种自我保护,它的理论基础在于权利保护和程序正义。本对对自诉权的构成要素、属性进行了分析。本文认为,自诉权的构成要素有三个方面:自诉权主体、自诉权的行为对象与效力以及自诉权的内容。自诉权的主要属性有三个方面:自诉权是一种自然之权也是法定之权、自诉权是一种诉权、自诉权是一种相对权也是一种非强制性权利。
