辨析中国专利制度中的禁止反悔规则 《最高人民法院关于审理侵犯专利权纠纷案件应用法律若干问题的解释》中关于“无效宣告程序中放弃的技术”的规定及相关案例分析

我国现在的专利制度似乎正在实施所谓的全面禁止反悔规则。一方面,在专利侵权诉讼中,专利权人可因专利申请过程中或者专利无效宣告程序中所作的限缩性修改和陈述而被禁止反悔,另一方面,在专利无效宣告程序和专利无效诉讼程序中,他又可因自己在专利侵权法律程序中的陈述而被禁止反     

The Role of Preschool Relational and Physical Aggression in the Transition to Kindergarten: Links With Social-Psychological Adjustment

Research Findings: The transition to kindergarten has important ramifications for future achievement and psychosocial outcomes. Research suggests that physical aggression may be related to difficulty during school transitions, yet no studies to date have examined the role of relational aggression in these transitions. This article examines how engagement in preschool physical and relational aggression predict psychosocial adjustment during the kindergarten school year. Observations and teacher reports of aggression were collected in preschool, and kindergarten teachers reported on student–teacher relationship quality, child internalizing problems, and peer acceptance in kindergarten. Results suggested that preschool physical aggression predicted reduced peer acceptance and increased conflict with the kindergarten teacher. High levels of relational aggression, when not combined with physical aggression, were related to more positive transitions to kindergarten in the domains assessed. Practice or Policy: These data lend support to the need for interventions among physically aggressive preschoolers that target not only concurrent behavior but also future aggression and adjustment in kindergarten. Thus, educators should work to encourage social influence in more prosocial ways among aggressive preschoolers.     

Phonological recoding,orthographic decoding,and comprehension skills during reading acquisition

To become skillful readers, children have to acquire the ability to translate printed words letter by letter into phonemic representations (phonological recoding) and the ability to recognize the written word forms holistically (orthographical decoding). Whereas phonological recoding is the key for learning to read and useful for recognizing unknown or low-frequent words, orthographical decoding is often more efficient and takes less time, thus facilitating reading processes on the sentence and text level. Several studies with English-speaking children provided evidence for the relevance of the two routes but the question whether and to what extent both word recognition skills contribute to reading comprehension in young German readers requires further clarification. Based on data from a cross-sectional study with German primary school children we investigated whether and to what extent both types of word recognition skills are associated with sentence (N = 666) and text comprehension skills (N = 149) and how these relationships develop from Grade 2 to 4. The results indicate that both phonological recoding skills and orthographical decoding skills are important for reading comprehension skills. Their relative weight does not change across grade levels.     

But I’m Married: Understanding Relationship Status and College Students’ Sexual Behaviors

Sexual health programs on college campuses are often directed toward single individuals with a focus on sexual risk. Using a sample of college students, this study examines how relationship status relates to sexual behaviors and may be a factor for sexual risk. Based on the study's results, expansion of sexual health programming on college campuses to include those married and in committed relationships is justified.     

Learning science content through socio-scientific issues-based instruction: a multi-level assessment study

Science educators have presented numerous conceptual and theoretical arguments in favor of teaching science through the exploration of socio-scientific issues (SSI). However, the empirical knowledge base regarding the extent to which SSI-based instruction supports student learning of science content is limited both in terms of the number of studies that have been conducted in this area and the quality of research. This research sought to answer two questions: (1) To what extent does SSI-based instruction support student learning of science content? and (2) How do assessments at variable distances from the curriculum reveal patterns of learning associated with SSI-based instruction? Sixty-nine secondary students taught by three teachers participated in the study. Three teachers implemented an SSI intervention focused on the use of biotechnology for identifying and treating sexually transmitted diseases. We found that students demonstrated statistically and practically significant gains in content knowledge as measured by both proximal and distal assessments. These findings support the claim that SSI-based teaching can foster content learning and improved performance on high-stakes tests.
