One hundred years of peptide chemistry

Emil Fischer is considered to be the founding father of the field of peptide chemistry and originator of the term peptide. In the beginning of the 20th century, Fischer had a clear vision to foresee the day when a protein would be synthesized. Subsequent to this brilliant beginning, progress however was slow for the next 50 years. In 1953, the chemical synthesis of oxytocin by duVigneaud was a landmark achievement. The subsequent decades witnessed the discovery of a vast number of biologically active peptides. The last three decades saw development of multiple simultaneous syntheses, peptide libraries and peptide vaccines. This article is a concise account of the types of peptides discovered and their biological role.     

One hundred years of Bohr model

In this article I shall present a brief review of the hundred-year young Bohr model of the atom. In particular, I will first introduce the Thomson and the Rutherford models of atoms, their shortcomings and then discuss in some detail the development of the atomic model by Niels Bohr. Further, I will mention its refinements at the hand of Sommerfeld and also its shortcomings. Finally, I will discuss the implication of this model in the development of quantum mechanics.     

Policy and Power: One hundred years of Local Education Authorities in Wales

The theme of this article is that, individually and collectively, the local education authorities in Wales have a distinctive history in the 20th century. The thesis is explored mainly by means of three case studies: the reaction of the local authorities to the Education Act of 1902, which eventually escalated into a national movement dubbed 'the Welsh revolt'; the response of some local authorities, particularly in industrial Wales, to the 1932 legislation which required them to replace their free secondary school places with special places; and the attempts of some councils to resist the largely clandestine attempts of the Ministry of Education and its Welsh Department to impose a tripartite system of secondary education against their wishes after 1944. This tradition of independent action in Wales bears on contemporary patterns of power and policy. The article concludes by suggesting that, in an education power structure now radically altered by the creation of the National Assembly for Wales in 1999, the local authorities are regarded more favourably than is the case in England and vested with significantly more responsibility, so making it likely that their future course will diverge increasingly from that of their English counterparts.     

教育学中国化百年反思

教育学作为一门学科,在中国一开始就是“进口”而来的,人们形象地称它是“舶来品”。教育学的引进与教育学的中国化几乎是相伴而生的,教育学中国化经历了六个阶段。解决教育学中国化问题,应注意中国的教育实际,使用科学的研究方法,正确处理学术研究与意识形态的关系,提倡教育学原创性研究,正确处理传承民族文化教育传统与借鉴国外教育理论之间的关系。
