20余年来大陆学者关于华侨华人与抗日战争研究述评

20余年来,大陆史学界对华侨与抗日战争关系的研究硕果累累.这些研究主要集中在华侨投身抗日救亡运动的原因和特点,华侨对祖国抗战的主要贡献,抗战期间有关各方的侨务政策,战时华侨领袖和著名人物以及华侨与太平洋战争等方面.     

我国现行羁押制度实施中的问题、原因及对策

羁押是我国侦查机关采取刑事强制措施所导致的一种后果,羁押制度设置的目的是为了防止犯罪嫌疑人有妨碍刑事诉讼或重新犯罪的行为。我国现行的羁押制度在具体实施中存在着诸多问题,羁押过程中违反法律、侵犯人权的行为时有发生。为了在维护被羁押人合法权益的前提下顺利推进刑事侦查工作,必须对我国现行的羁押制度进行改革。     

Causes of brain drain and solutions: The Taiwan experience

Over the years, Taiwan has experienced “brain drain”, as more than 80 percent of its students who completed their graduate study in the United States have failed to return. Instead, they have found their ways into the faculties of American colleges and universities or employment opportunities in various research organizations and industries. This article examines brain drain, its origin in Taiwan, and government response. One of the major findings of this study is that the elite emigration in Taiwan has been caused by a host of complex academic, social, economic, and personal factors. Second, Taiwan’s brain drain into the United States is primarily a case of “education and migration.” It is an outflow of college graduates, not an exodus of trained scientists and engineers; therefore, Taiwan’s manpower loss in the short run is not as serious as the case where mature and experienced scientists and professionals leave. Furthermore, whereas a large number of college graduates leave each year to study abroad, a much larger number of the graduating class does remain in Taiwan. To reverse Taiwan’s brain drain, the government of the Republic of China (ROC) has already implemented an ambitious program to recruit Taiwan’s highly trained talents from overseas. Taiwan’s successful experience could be emulated by other developing countries. Shirley L.

新型鸡痘病毒穿梭载体的构建及其体外表达

为构建用于筛选的新型鸡痘病毒载体,采用染色体步移技术对鸡痘病毒282E4株TK基因的下游序列进行测序,并结合扩增出的左右同源重组臂TKL、TKR片段、启动子、MCS及终止信号构建出三表达盒穿梭载体pTKE3。采用基因工程技术将绿色荧光蛋白EGFP基因克隆入3个启动子的下游,构建出pTKE3-A、pTKE3-B、pTKE3-C验证表达盒质粒。结果显示,构建的3个验证质粒分别与鸡痘病毒282E4株共转染鸡胚成纤维细胞,均可在转染12h后观察到绿色荧光。结果表明,构建的三表达盒载体均可成功表达外源基因,这为进一步构建多价重组鸡痘病毒活载体疫苗奠定了基础。     

手印固有荧光的检测

目的提高手印的成功率.方法用自然光、多波段光源对五种纸张上的汗液与油脂手印进行检验.结果470纳米下的固有荧光检测对手印显现非常有效.结论手印的固有荧光检测应作为手印显现标准程序的第一步.     

胶带粘面上的手印显现

论就业成本与高职毕业生就业的关系

随着高校扩招后毕业生就业高峰的到来,高职院校毕业生就业面临着种种问题和挑战。高职学生为了能够就业,纷纷增加就业成本,当然就业成本与就业率存在着某种程度的正比例关系,但两者关系并不是绝对的,我们应转变理念,从多方面降低高职学生的就业成本,同时对高职院校学生的就业进行机制创新,从而真正提高高职院校学生的就业率。     

Effects of a competency-based counseling training program for correctional officers

The purposes of this study were (a) to determine whether a competency-based counseling training program can be effective in developing the counseling skills of correctional officers with diverse backgrounds and (b) to examine if participants would demonstrate positive changes in counseling skills regardless of their differences among a variety of demographic variables. One hundred and six correctional officers were selected to participate in this study. Both qualitative and quantitative research methods were applied for collecting and analyzing data. The results indicate that the participants' counseling skills were significantly improved. Because the participants demonstrated positive changes in their overall counseling skills, the present research further supports no significant difference among a variety of variables. The training program also brought out deeper reflection on the significant learning experiences, greater theoretical knowledge, as well as greater understanding of the counseling work for the participants.     

mRNA荧光复合扩增系统鉴别正常和异常精液初探

目的构建mRNA荧光复合扩增体系,实现对不同种类精液(尤其是无精症精液)的区分鉴别。方法收集正常、少精症及无精症的精液样本,制备精斑样本后提取细胞总RNA,利用逆转录PCR技术扩增2个精子特异mRNA标记(PRM1、PRM2)、2个精浆特异mRNA标记(TGM4、SEMG1)和2个管家基因mRNA标记(TEF、UCE)。结果正常精液样本可检测到全部精液mRNA标记表达;少精症精液样本虽然可检测到全部mRNA标记表达,但精子特异mRNA标记表达量较低;无精症精液样本不能检测到精子mRNA标记,只能检测到精浆特异mRNA标记。结论利用mRNA荧光复合扩增系统可以实现对正常和无精症精液的区分,而正常精液和少精症精液相比差异无统计学意义。
