产学合作中的知识生产效率——基于“模式Ⅱ”的实证研究

 本文利用1998-2008年中国29个省市高校与企业的面板数据,以产学联合申请专利数为产出变量,通过构建随机前沿知识生产函数,探究了“模式Ⅱ”情境下应用导向、跨学科研究、参与者异质性、组织多样性对知识生产效率的影响,并对比分析了区域间知识生产的平均效率及影响因素的边际效应。研究表明：我国区域知识生产效率水平的格局为：东部＞中部＞西部;“模式Ⅱ”情境下企业的人才与资金投入对知识生产有显著的正向影响,而高校知识存量对产学合作中的知识生产贡献度更高,并且该过程具有规模报酬递减的属性;应用导向等影响因素对知识生产效率均有显著的正向影响,但是存在区域与时效上的差异性,应用导向与参与者异质性对东部地区的边际影响较大,东部地区企业参与知识生产的边际效果高于中西部地区,政府介入产学合作对中西部地区知识生产具有长效的正向影响。

mtDNA analysis of the human remains buried in the sarcophagus of Federico II

The sarcophagus containing the remains of Federico II, located in the Cathedral of Palermo (Sicily, Italy), was opened on 1998 to perform a multidisciplinary survey [1]. Next to the remains of Federico II and in close contact with them were laying two other skeletons belonging, according to historical records, to Pietro II di Aragona and to an anonymous person (“The Third Individual”), probably a woman. The bones appeared severely deteriorated. Chemical analysis performed on bone samples excluded that the bodies underwent some kind of embalming process. The analysis of mtDNA from bone samples taken from the three skeletons was successful in only one of the two labs involved. The HVR1-mtDNA sequence (region: from nt 16,035 to nt 16,395), obtained from the bone samples of Federico II and “The Third Individual” appear identical but bear double peaks at the same nucleotide positions, suggesting mixing (i.e. contamination) of different mtDNA types. The HVR1 sequence obtained from the bone sample of Pietro II di Aragona does not present double peaks and differ from the Cambridge Reference Sequence (CRS) at six nucleotide positions. Cloning experiment of the Federico II amplicon demonstrated that the mixed mtDNA types are only two: one identical to CRS, the other identical to the sequence of Pietro II di Aragona. A reconstruction of these data are proposed in the Discussion. Due to the problematic context in which this study was carried out (mixed and deteriorated biological material, failure to replicate results in two different labs), our results and reconstruction can only be offered on a tentative basis. It is hoped that the data presented in this study will reveal useful, for future comparison, if further molecular genetics research will be carried out on the royal dynasties that ruled Sicily in the early centuries of the past millennium.

The effects of affective and cognitive treatment on attitude change toward ethnic minority groups

The purpose of this study was to compare the effects of cognitive and affective treatments on the attitudes of white university students in Hawaii (a place where many ethnic minority groups live with little overt discrimination and where no one racial group, such as the whites, is in the majority) toward ethnic minority groups. It was hypothesized that the rank order of the groups from most favorable to least favorable in social distance and attitude for and against ethnic minority groups, would be: Affective Treatment, Cognitive Treatment, Hawaii Control, and Mainland Comparison Group. The Social Distance Scale and Prejudice and Rationality Scale were used as pretest and posttest instruments in the Fall, 1980 with 94 Brigham Young University—Hawaii Campus (BYU—HC)and30 Brigham Young University (BYU) in Utah undergraduate students. Analysis of covariance led to supporting the three hypotheses at the 0.01 significance level. It was found that the Affective Treatment Group consistently had a greater change in attitude toward ethnic minorities followed by the Cognitive, Hawaii Control, and Mainland Comparison Groups. It was concluded that the affective treatment was the most effective in changing attitudes toward ethnic minority groups.

Verbal Fluency and Verbal Short-Term Memory in Adults with Down Syndrome and Unspecified Intellectual Disability

The purpose of this study was to examine verbal fluency and verbal short-term memory in 12 adults with Down syndrome (DS) and 12 adults with Intellectual Disability (ID) of unspecified origin, matched for receptive vocabulary and chronological age. Participants’ performance was assessed on two conditions of a verbal fluency test, namely, semantic and phonemic fluency. In addition to the total number of correct words produced, the use of clustering and switching strategies was also evaluated. In order to investigate the likely relations of verbal short-term memory with the test variables, a digit span task was administered. According to the results of the study, the two groups differed significantly on the average phonemic cluster size, with the ID group outperforming the DS group. Regarding the within-group comparisons, a relatively similar pattern of results was found for the two groups, indicating higher scores on all the measures involved in the semantic test than the phonemic one. The examination of the relation of verbal short-term memory with the verbal fluency test measures revealed that, in the DS group, only the total words produced in the semantic and the phonemic test and the number of phonemic switches were significantly associated with verbal short-term memory. Additionally, in both groups, word productivity in the semantic and the phonemic test was positively associated with the number of switches. The observed similarities and differences in the performance of the two groups, as well as the associations that emerged among the test variables in each group, are discussed.
