Does School Tracking Affect Equality of Opportunity? New International Evidence This paper investigates whether at the interaction between family background and school tracking affects human capital accumulation. Our a priori view is that more tracking should reinforce the role of parental privilege, and thereby reduce equality of opportunity. Compared to the current literature, which focuses o...

Researchers continue to be interested in those subjects generally regarded as fundamental to bilingual education: second language acquisition, biliteracy, curriculum development, dual language pedagogy, the relation of first and second language development, assessment of language development in bilinguals, and others. Studies in these areas should and no doubt will continue. My task in this pre...

this paper proposes a control strategy for a cable-suspended robot based on sliding mode approach (smc) which is faced to external disturbances and parametric uncertainties. this control algorithm is based on lyapunov technique which is able to provide the stability of the end-effecter during tracking a desired path with an acceptable precision. the main contribution of the paper is to calculat...

Conventional history of the predominant, research-based model of business education (RBM) traces its origins to programs initiated by the Ford Foundation after World War II. This paper maps the elite network responsible for developing behavioral science and the Ford Foundation agenda. Archival records of the actions taken by central nodes in the network permit identification of the original vis...

This article reviews trends and issues related to adult nephrology fellowship education in the United States. The number of nephrology fellowship programs and trainees has continued to increase slowly despite limitations in funding of graduate medical education. The use of the Electronic Residency Application System has provided information for the first time on the number, demographics, and be...

In recent years there has been significant growth in the use of 3D virtual worlds for e-learning and distance education. These immersive environments offer the ability to create complex, highly interactive simulations using in-world modelling and scripting tools. Virtual learning environments support teaching and learning in an educational context, offering the functionality to manage the prese...

This is the first of two papers that provide extensive data and analysis on the two major approaches to clinical veterinary education, which either provide students with experience of a broad range of species (often defined as omni/general clinical competence), or just a few species (sometimes just one), usually termed 'tracking'. Together the two papers provide a detailed analysis of these two...

Organizations are introducing biometric devices into various sections of the economy for various reasons. What began as a security feature for a limited number of government organizations has been adapted to such diverse uses as paying for school children’s lunches to tracking employees’ work attendance. From an organizational perspective, justifications for use of biometric devices are plentif...

object detection plays an important role in successfulness of a wide range ofapplications that involve images as input data. in this paper we have presented anew approach for background modeling by nonconsecutive frames differencing.direction and velocity of moving objects have been extracted in order to get anappropriate sequence of frames to perform frame subtraction. stationary parts ofbackg...
