英语内在格习得的语段伸缩及其参照—认知的序列离散性

本文通过汉译英内在格句翻译测试探究了内在格习得进程中的语段伸缩与参照—认知的序列离散样态.结果显示:四类内在格句的习得难度影响到语段的局部性伸展长度、收窄长度以及语段接口重装形态;三个组别在参照点与认知标的上表征为铰链型序列组合(弱震颤离散化)、黏着型序列组合(强震颤离散化)以及松散型序列组合(超强震颤离散化).语段伸...

山西省高校新聘专任教师队伍结构探析

近五年,山西省高校新聘专任教师队伍与以前相比,在性别比例、学历层次、学科比例等方面发生了一些新变化。本文以山西省高校教师岗前培训所获取的第一手统计数据为依据,着重对这些变化及其背后的动因进行阐述和探讨,并结合山西经济社会发展实际,提出了一些建设性的解决方案。     

从社会调查看民国时期华北地区的人口状况

从李景汉和当时其他学者的调查入手,考察华北地区人口的性别比例和增长类型,从而引出对人地关系的探讨,并且以后者为重点。同时,从人地关系的分析中,还可以得知农民并非是一个愚昧、落后的群体,他们对农业生产、日常生活的安排都是有一定合理性的,在他们的生活中潜藏着一种朴素的智慧。     

Age and sex influences on running mechanics and coordination variability

The purpose of this study was to examine the impact of age on running mechanics separately for male and female runners and to quantify sex differences in running mechanics and coordination variability for older runners. Kinematics and kinetics were captured for 20 younger (10 male) and 20 older (10 male) adults running overground at 3.5 m · s^?1. A modified vector coding technique was used to calculate segment coordination variability. Lower extremity joint angles, moments and segment coordination variability were compared between age and sex groups. Significant sex–age interaction effects were found for heel-strike hip flexion and ankle in/eversion angles and peak ankle dorsiflexion angle. In older adults, mid-stance knee flexion angle, ankle inversion and abduction moments and hip abduction and external rotation moments differed by sex. Older compared with younger females had reduced coordination variability in the thigh–shank transverse plane couple but greater coordination variability for the shank rotation–foot eversion couple in early stance. These results suggest there may be a non-equivalent aging process in the movement mechanics for males and females. The age and sex differences in running mechanics and coordination variability highlight the need for sex-based analyses for future studies examining injury risk with age.

制约逻辑与情报推理

逻辑科学在情报学学科中几乎主要地被应用于情报检索领域,而情报检索领域中涉及推理的内容主要地散见于人工智能推理机制中。人工智能研究以正统数理逻辑为其逻辑理论工具。由于正统数理逻辑把原本能确保不循环的推理格式处理成同语反复的恒真的真值函数。因而建立在这种逻辑理论基础之上的人工智能专家系统并不能真正实现从已知到新知的必然过渡。情报推理仍需要寻求一种更合适的逻辑理论工具。     

Adolescents’ motives for selling sex in a welfare state – A Swedish national study

In addition to money or other compensation, other motives for selling sex may be important in a welfare country such as Sweden. The aim of this study was to carry out an exploratory investigation of adolescents’ motives for selling sex in a population-based survey in Sweden. A total of 5839 adolescents from the third year of Swedish high school, mean age 18.0 years, participated in the study. The response rate was 59.7% and 51 students (0.9%) reported having sold sex. Exploratory factor analysis and hierarchical cluster analysis were used to identify groups of adolescents according to underlying motives for selling sex. Further analyses were carried out for characteristics of selling sex and risk factors. Three groups of adolescents were categorized according to their motives for selling sex: Adolescents reporting; 1) Emotional reasons, being at a greater risk of sexual abuse, using sex as a means of self-injury and having a non-heterosexual orientation. 2) Material but no Emotional reasons, who more often receive money as compensation and selling sex to a person over 25 years of age, and 3) Pleasure or no underlying motive for selling sex reported, who were mostly heterosexual males selling sex to a person under 25 years of age, the buyer was not known from the Internet, the reward was seldom money and this group was less exposed to penetrative sexual abuse or using sex as a means of self-injury. In conclusion, adolescents selling sex are a heterogeneous group in regard to underlying motives.
