“应然”与“实然”视角下体育竞赛表演权的法律保护研究

体育竞赛表演的法律保护一直是倍受争议的问题.在"实然"视角下,国际条约及有关法规没有把体育竞赛表演纳入表演的法律保护中,我国著作权法及实施条例也没有把体育竞赛表演纳入表演法律保护中.在"应然"视角下,从洛克的劳动理论、人格财产论、经济激励理论及社会现实需要的角度论述了体育竞赛表演保护的必要性和可行性,认为体育舞蹈、武术、花样游泳、花样滑冰、艺术体操、健美操等体育项目应受著作权法保护.     

论检察机关如何应对最高人民法院《关于办理刑事案件排除非法证据若干问题的规定》的出台对刑事案件发回重审的影响

多次、反复、随意发回重审问题一直是中国司法审判中存在的问题,而最高人民法院《关于办理刑事案件排除非法证据若干问题的规定》的出台增加了需要发回重审的刑事案件的数量,包括：二审法院对排除非法证据的请求不予理睬应当发回重审;二审法院对排除非法证据的请求不置可否,而实际上会以事实不清、证据不足为由发回重审;一审法院没有支持排除非法证据的请求,而二审法院认为应当排除的,取证行为严重侵害被追诉人宪法权利的情况下,应发回重审;一审法院支持排除非法证据的请求,而二审法院认为不应当排除的,一审法院没有对证据进行质证的情况下,案件应发回重审。对此,检察机关应当建立检察机关内部、外部的联动沟通机制,强化检察机关的法律监督职责,加强对公安机关侦查程序合法性的监督以及法院可能滥用发回重审裁量权的监督。

The effect of language specific factors on early written composition: the role of spelling,oral language and text generation skills in a shallow orthography

Spelling skills have been identified as one of the major barriers to written text production in young English writers. By contrast oral language skills and text generation have been found to be less influential in the texts produced by beginning writers. To date, our understanding of the role of spelling skills in transparent orthographies is limited. The current study addressed this gap by examining the contribution of spelling, oral language and text generation skills in written text production in Italian beginner writers. Eighty-three children aged 7–8 years participated in the study. Spelling, lexical retrieval, receptive grammar, and written sentence generation and reformulation skills were assessed and children were asked to write a text on a set topic. A factor analysis revealed that the children’s written text production was captured by three factors: productivity, complexity and accuracy. In contrast to results from children learning to write in opaque orthographies, such as English, this study showed that receptive grammar and written sentence generation skills accounted for significant variance in measures of productivity, complexity and accuracy in Italian children’s written text production. Spelling skills contributed to text accuracy and quality and explained more variance than receptive grammar in microstructural accuracy. By contrast, oral grammatical skills explained more variance in text quality than spelling. The current study shows the differential impact of language systems, such as Italian, on written text production. Implications for assessment and instruction are outlined.
