情态动词否定之研究

Palmer认为在英语语法中 ,最难描写的莫过于情态助动词系统 (Palmer,1 979:preface)。情态动词之所以纷繁复杂、难以描写是因为它们在各种英语文体中使用频率极高 ,并且表达的意义与人的情感和意念有着密切关系。由于情态动词的意义的多样性和模糊性 ,其否定形式及范围也是复杂多变的。我们可以依据Palmer对三类情态动词(推测性、义务性、原动性 )和两种情态级别 (可能级、必定级 )的划分 ,对情态动词的否定范围及语义进行分类分级研究 ;同时 ,鉴于可能级和必定级情态动词否定之间的语义约同现象 ,对逻辑等式Not -possible =Necessary -not;Not -necessary=Possible -not在情态动词句式中的操作规律加以探讨 ,结果表明该等式为解释情态动词否定形式间的互补现象提供了逻辑依据

虚拟实验在人才培养中的作用

虚拟仪器系统是测控技术和计算机技术相结合的产物。虚拟仪器在教学中的应用,改革了传统的实验教学方法,有效地强化了实验教学的效果。在阐述运用虚拟仪器技术改革实验教学方法的基础上,探讨了虚拟实验对人才培养的作用和意义,认为在当前高校连年扩大招生规模、在校生迅速增加、实验教学仪器设备不适应教育发展要求、高校实验教学与工程技术实际脱节的情况下,采用虚拟仪器实验能弥补传统仪器实验教学存在的不足,符合高校教学改革的发展趋势和培养人才的实际需要。     

“需要层次论”与高校思想政治工作

心理学家马斯洛认为人的需要共分为五个层次,并由低级需要向高级需要递进.辩证的运用这一理论,重视并合理满足高校师生的需要,以此达到激励作用,提高思想政治工作的实效性,是我们应该"拿来"并加以研究的课题.

Forced to work and liberated from work

The work-welfare nexus is essential in all social policy regimes. The question is in what situations individuals should be entitled to social welfare benefits and in which situations they should be obliged to work. Social welfare law and administrative practices define mechanisms that separate the deserving poor from people able to work. This article analyses the functions and character of these "separation mechanisms" in Sweden during three periods in history: a) in rural society in the late 19th century; b) in industrial society during the successful years of the Swedish model from World War II until the late 1970s; and c) the present, including the period of welfare retrenchment and reconsideration since the early 1980s. The conclusion is that Swedish social policy has always been strongly work-oriented, but the specific form and content of the work ethic has varied under the influence of different ideologies and handled in different social policy institutions. Under specific conditions the work line has been either generous or restrictive and it has been based on structural attempts to improve the opportunities to work as well as on attempts to strongly pressure the individual to work. The work line of today is seen as an interesting attempt to combine an effort to create good work through improved work conditions and an effort to reinforce elements of work enforcement in the social insurance system.     

Employment and filial relations: Is there a conflict?

Since children, particularly daughters, are among the most important sources of help and support for older Americans, it has been suggested that women's increasing employment will affect filial relations. Empirical evidence on this issue is inconsistent, in part due to the use of nonprobability samples. Few studies have measured effects for men. We attempt to broaden the scope of this question beyond help to the frail elderly by asking whether employment affects filial relations in general. We examine effects of hours employed on telephone contact, visiting, feelings of closeness, filial attitudes, and assistance to biological parents, for an area probability sample of men and women over 40. There are no effects of employment for men or women on contact, closeness, or assistance. For the vast majority of this population sample, contact and assistance involve few hours per week, and thus do not seem to conflict with employment.     

论学生社团建设与高校思想政治工作的融合
