Introduction to this Special Issue     

Lina?KashyapEmail author 《International journal for the advancement of counseling》2004,26(4):337-339

In 2001, for the first time in the history of the International Association for Counselling, International Conference was held in a developing Asian country–India, with the theme Families in Transition–Counselling in Transition–Meeting the Challenges Ahead. This special issue contains some of the presentations made by Indian participants during this conference which best reflect the challenges and diversities of counseling efforts with families in India. The first article was specially written for this issue in order to give an international relationship of this journal an in depth contextual understanding of Indian families in transition and the challenges they pose to the contemporary Indian counselor. Two articles are reflected to counseling families affected by socio-politial and economic changes. Five authors have written on counseling related to physical and mental disability/addiction and last two articles are reflected to authors experiences as family counselors.  相似文献   

Kinetics study on biomass pyrolysis for fuel gas production     

陈冠益  方梦祥  ANDRIES J  骆仲泱  SPLIETHOFF H  岑可法 《浙江大学学报(A卷英文版)》2003,4(4):441-447

Kinetic knowledge is of great importance in achieving good control of the pyrolysis and gasification process and optimising system design. An overall kinetic pyrolysis scheme is therefore addressed here. The kinetic modelling incorporates the following basic steps: the degradation of the virgin biomass materials into primary products (tar, gas and semi-char), the decomposition of primary tar into secondary products and the continuous interaction between primary gas and char. The last step is disregarded completely by models in the literature. Analysis and comparison of predicted results from different kinetic schemes and experimental data on our fixed bed pyrolyser yielded very positive evidence to support our kinetic scheme.

普通话二字组词语的动态声调     

韩军华 《滨州学院学报》2002,18(1):38-40

普通话二字组词语不同的声调组合方式 ,使前后位声调产生不同的动态变化形式。前位声调的动态变化明显表现在上声调变为低降调和中升调上 ;后位声调的动态变化则表现在调值的明显改变上。后位声调的动态变化更为普遍 ,应该引起足够的重视  相似文献   

Does prior mathematics knowledge really lead to variation in elementary statistics performance? Evidence from a developing country     

George Woodward  Don Galagedera 《International Journal of Educational Development》2006,26(6):631-639

A model incorporating prerequisite mathematics performance and other variables deemed to be associated with learning elementary statistics (ES) is developed. The relationship between ES performance and the explanatory variables is well represented by the logistics form. Aptitude, effort and motivation are the only significant explanatory variables of ES performance. Since prerequisite mathematics is not significant, statistical thinking at the tertiary level may be mostly intuitive and non-mathematical. Students with low aptitude experience increasing returns to effort over the first half of the feasible effort interval, while high-aptitude students experience diminishing returns at all levels of effort. The levels of effort required to achieve a minimum pass are interpreted.  相似文献   

The robed baron: The academic profession in the Italian university     

Martinotti  Guido  Giasanti  Alberto 《Higher Education》1977,6(2):189-207

The Italian academic profession is subject to complex bureaucratic structures and many strains as the result of rapid academic expansion but very limited resources. The ladder up the academic profession is both complicated and very difficult. Norms of professionalism are in conflict with the traditional patron system. This paper analyzes the current situation of the academic profession in Italian universities, and stresses a discussion of the career ladder and how it works in the academic system.Data for this paper have been collected as part of a research grant no. 73.00982.09 from the Consiglio Nazionale delle Ricerche.  相似文献

Teaching Undergraduate Mathematics on the Internet     

Johann?EngelbrechtEmail author  Ansie?Harding 《Educational Studies in Mathematics》2005,60(2):253-266

This is Part 2 of a two-part study of how APOS theory may be used to provide cognitive explanations of how students and mathematicians might think about the concept of infinity. We discuss infinite processes, describe how the mental mechanisms of interiorization and encapsulation can be used to conceive of an infinite process as a completed totality, explain the relationship between infinite processes and the objects that may result from them, and apply our analyses to certain mathematical issues related to infinity.  相似文献
