本文对青海省职业教育发展中存在的突出问题进行了较深入地分析,针对这些问题,从完善青海省职业教育办学模式、改善教学方式、提高教学水平等方面提出了一些切实可行的建议。     

Die ‘Krüppelfürsorge’ in der Weimarer Republik. Zwischen eigenem Standpunkt und diskursiver Anschlussfähigkeit an eugenische Argumentationsstrukturen

The ‘Krüppelfürsorge’ during the Weimar Republic. Oscillating between an Own Position and the Adoption of Eugenic Arguments. This article examines the discourse about physical disability led by the German ‘Krüppelfürsor‐ge’. It deals with the exhibition GeSoLei (Gesundheitspflege, soziale Fürsorge and Leibesübungen), which took place in Düsseldorf in 1926. The GeSoLei was one of the most popular platforms of the healthy and aesthetic body in the 1920s. It stood in the context of the German ‘national recovery’ after World War I and collected all types of medical, social and athletic professionals to expose their work to a broader audience. Also representatives of the so called ‘Krüppelfürsorge’ presented themselves and at the same time their perspective on people with physical disabilities on this exhibition. The article points out the ambivalent character of their perspective and shows the mixture of including and excluding people with physical disabilities, which was typical for the view of the ‘Krüppelfürsorge’. It demonstrates that the ‘Krüppelfürsorger’ on the one hand were quite progressive towards people with disabilities, but on the other hand showed a striking openness towards eugenic values.     

The Secret History of TANU: Rumor,Historiography and Muslim Unrest in Contemporary Dar Es Salaam

This article explores historical rumors and narratives told by Muslims of Dar es Salaam, contending that Julius Nyerere, TANU founder and first president of independent Tanzania, was an inexperienced schoolteacher thrust into the role of political activist through sponsorship of the Muslim community. This history was allegedly hidden by the current government to cover up not only Nyerere’s meteoric rise to a position of leadership, but also subsequent actions that wrested the movement from Muslims and other early TANU leaders to monopolize power for himself and upcountry elites. Just as academic historians critique the teleological trajectory of many nationalist histories, these rumors critique Tanzanian nationalist history through appropriating its historiographic form to forefront postcolonial grievances. The discursive nature of such rumors articulates the discontent permeating the postcolonial Muslim community of Dar es Salaam. And as political speech in action, rumors are instrumental in mobilizing new postcolonial political configurations.     

Design Methodology for Seismic Upgrading of Substandard Reinforced Concrete Structures

This article presents a design methodology for seismic upgrading of existing reinforced concrete (RC) buildings. The methodology is based on the modification of the deflected shape of the structure so as to achieve a near-uniform distribution of interstorey drift along the building height, thereby eliminating damage localization. Yield Point Spectra are utilized for the definition of demand and a direct displacement-based design approach is implemented. The fundamental steps of the method are described in detail, including a systematic evaluation of assumptions and limitations. A full-scale tested structure is used as a case study for assessment and verification of the proposed methodology. Alternative retrofit scenarios are set according to target response and performance levels. The role of the target deflected response shape and its influence on the outcome of the retrofit strategy is investigated. The viability of the alternative retrofit scenarios is studied for different ground motions including near-fault earthquake records.     

20世纪美国残疾人就业权利的缘起、制度化与困境

在某种意义上,20世纪的美国历史也是一部残疾人的民权运动史。如果说经济大萧条初步唤醒了残疾人的就业权利意识,两次世界大战开启了美国伤残军人康复与就业援助的机制建设,第三次科技革命则加速了残疾人就业权利保障的制度化进程。从公共就业计划、残疾人社会保障保险计划、补充收入保障计划,到《1973年残疾人康复法》,再到《1990年美国残疾人法》,残疾人的就业权利经历了被漠视、依附于福利救济、向实现平等权利转变等阶段,给美国的政治、经济、社会、思想领域留下了诸多挑战和值得思考的问题。由于法律在解决社会问题上存有局限、残疾人对各种福利保障资助的依赖、根深蒂固的偏见等因素,美国残疾人争取平等权利之路仍任重而道远。     

Design and Assessment Spectra for Retrofitting of RC Buildings

This article presents a novel approach for deriving Retrofit Design Spectra (RDS) that are intended for use in preliminary development and assessment of seismic upgrading scenarios of existing structures. The new spectral representation relates the characteristics of the intervention method chosen as the core of the upgrading strategy, with the ductility and strength demand of the retrofitted structure. The methodology utilized for the derivation of the RDS is based on the Capacity Spectrum Method where the capacity curve is described by relationships for global and local intervention methods that are parameterized in terms of fundamental response quantities. The proposed spectra provide direct insight into the complex interrelation between the characteristics of the intervention method and the implications of the upgrading scenario on demand. Alternative retrofit solutions are thus assessed in an efficient way. A case study is used to illustrate practical application of the new approach.     

SEISMIC REHABILITATION OF SHORT RECTANGULAR RC COLUMNS

Non-ductile response of structural elements, particularly columns, has been the cause of numerous documented failures during earthquakes. The objective of this experimental study was to evaluate the non-linear behaviour of non-ductile reinforced concrete short columns under lateral cyclic deformations and to evaluate rehabilitation schemes. Three reinforced concrete short columns were tested under cyclic lateral loads and constant axial load. The behaviour and effectiveness of different rehabilitation systems using carbon fibre reinforced polymers (CFRP) were investigated. Two different techniques to improve concrete confinement were used in the two rehabilitated specimens. It was found that it is possible to eliminate the non-ductile modes of failure of short column using anchored CFRP wraps. In addition, an analytical model to predict the confining effect and the total shear resistance of rectangular reinforced concrete columns with anchored fibre wraps was introduced. The confinement model is an extension to an available model for concrete confined by steel reinforcement. The model was used to predict the shear capacity of the tested specimens and has shown good results.     

Assessment of Multi-Wythe Stone Masonry Subjected to Seismic Hazards

Heritage stone buildings are typically vulnerable to seismic events. Results of an experimental program were analyzed to evaluate the shear strength and intrinsic damping of stone masonry representative of the West Block of the Canadian Parliamentary Precinct in Ottawa. Eight representative wall specimens with different rehabilitation schemes had been tested under different static and dynamic loadings. Each wall had wythes of sandstone and limestone connected by a rubble core. The results show the shear strength of the walls could be predicted accurately and that no strengthening scheme was particularly beneficial. The effective viscous damping ratios varied between 7 and 9%.     

The Peerage and the Revolution of 1688

Four points support the thesis that the English nobility played a critical role in the revolution. First, the later 17th‐century aristocracy was energetic, wealthy, and connected in ways facilitating political action within, and subsequently outside, the parliamentary arena. Second, it was a class conscious of status and privilege which many policies of James II bumped up against inadvertently, but often with negative consequence. Third, most peers were observant protestants in an age when religious belief, or at least the externals of practice, still mattered greatly. Fourth, habits of deference and traditional spheres of influence at the local level remained surprisingly intact despite intensive royal effort to reshape the lieutenancies, commissions of the peace, and municipal and other corporate bodies. Resistance to repeal of the Test Acts was the issue around which a leadership group emerged in the aristocracy. Initially it focused on a parliamentary solution in which an absolute majority in the house of lords could be counted on to stand firm no matter how the Commons might vote. In the absence of that opportunity and in the face of other events regarded as inimical to class, nation and the protestant interest, many peers turned away from natural alliance with the crown and – in the case of a forward group – conspired with the prince of Orange. Ultimately, more than a third of the nobility aligned itself with those peers intent on constraining the king's freedom of political action, an important factor contributing to his decision to flee.
