流动的光影——从电影色情描写看女性边缘文化地位

色情渗入了整个消费领域,而女性身体与色情描写有着天然联系,在色情电影中尤其突出,在电影中,女性的美丽、罪恶都成为了消费的对象,女性的地往日益边缘化。     

Bovine TMEM95 gene: Polymorphisms detecting in five Chinese indigenous cattle breeds and their association with growth traits

BackgroundTransmembrane protein 95 (TMEM95) plays a role in male fertility. Previous studies showed that genes with a significant impact on reproductive traits can also affect the growth traits of livestock. Thus, we speculated that the genetic variation of TMEM95 gene may have effects on growth traits of cattle.ResultsTwo SNPs were genotyped. The rs136174626 and rs41904693 were in the intron 4 and 3′-untranslated region, respectively. The linkage disequilibrium analysis illustrated that these two loci were not linked. The rs136174626 was associated with six growth traits of Nanyang cattle, four traits of Luxi cattle, and three traits of Ji’an cattle. For rs41904693 locus, the GG individuals had greater body height and abdominal girth in Ji’ an cattle than TT and TG individuals. In Jinnan cattle, GG and TT individuals had greater body height, height at hip cross, body length, and heart girth than TG individuals. The potential splice site prediction results suggest that the rs136174626 may influence the splicing efficiency of TMEM95, and the miRNA binding site prediction results showed that the rs41904693 may influence the expression of TMEM95 by affecting the binding efficiency of Bta-miR-1584 and TMEM95 3′-UTR.ConclusionsThe findings of the study suggested that the two SNPs in TMEM95 could be a reliable basis for molecular breeding in cattle.How to cite: Guo X, Zhang S, Yang H, et al.

Hepatic Enzyme’s Reference Intervals and Their Modulating Factors in Western Indian Population

The reference intervals (RIs) of serum aminotransferases and Gamma-glutamyl transferase (GGT) have been established many years ago. Recent RIs are not available. The prospective study was conducted to re-evaluate the RIs of liver enzymes and the effect of demographic and anthropometric variables on them in western Indian population. A total of 1059 blood donors comprised the study population. Anthropometry and serum liver enzymes levels were measured. Subjects were categorized into normal weight and overweight by using body mass index (BMI) and waist circumference (WC). For RI determination, non-parametric methodology recommended by IFCC/CLSI was adopted. Mann–Whitney test and Spearman’s rank correlation were used for statistical analysis. Upper limit of normal reference value of liver enzymes were lower in female compared to male. (ALT—23.55 F vs 36.00 M, GGT—34.58 F vs 36.20 M) When RI of liver enzymes were calculated according to body mass index, the upper limit of normal of ALT and GGT were higher in overweight group compared to normal weight group. (ALT—38.00 vs 27.00 IU/L and GGT—37.59 vs 35.26 IU/L). In both male and female, liver enzymes correlated significantly with age. WC and BMI were positively correlated with AST, ALT and GGT in both subgroups and the correlation was stronger in male. Demographic factors should be considered for making liver enzyme tests more clinically relevant. Gender based partitioning should be adopted for serum alanine aminotransferase (ALT) and GGT reference values for Western Indian population.     

古代形神问题的系统解读——兼论“心之官则思”的科学性

古代形神或身心问题是小系统与大系统、低层次与高层次之间的关系问题。优化和调整人的心理结构可以促成创造性思维形成的观点是证明“心之官则思”科学性的逻辑基础。不能一面承认心理结构是形成思维活动的基础,一面又否认“心之官则思”的科学性;其实,二者在本质内容上是一致的。对“心之官则思”的科学解读,标志着用系统方法研究形神问题的成功。

Some Consequences of Prompting Novice Physics Students to Construct Force Diagrams

We conducted a series of experiments to investigate the extent to which prompting the construction of a force diagram affects student solutions to simple mechanics problems. A total of 891 university introductory physics students were given typical force and motion problems under one of the two conditions: when a force diagram was or was not prompted as part of the solution. Results indicated that students who were prompted to draw the force diagram were less likely to obtain a correct solution than those who were not prompted to solve the problem in any particular way. Analysis of the solution methods revealed that those students prompted to use a diagram tended to use the formally taught problem‐solving method, and those students not prompted to draw a force diagram tended to use more intuitive methods. Students who were prompted to draw diagrams were also more likely to depict incorrect forces. These results may be explained by two factors. First, novice students may simply be more effective using intuitive, situational reasoning than using new formal methods. Second, prompting the construction of a force diagram may be misinterpreted by the student as a separate task, unrelated to solving the problem. For instruction, the results of this study imply that ignoring students’ prior abilities to solve problems and their necessary developmental stages in learning formal problem‐solving techniques may lead to serious mismatches in what is taught and what is intended to be learned.
