Working Conditions Laws Report 2012: A Global Review

[Excerpt] Labour legislation to address working conditions can cover an array of subjects that affect the employment relationship and workers’ well-being in the workplace. This report will focus on legislation regarding three important elements: working time (Chapter 1), maternity protection (Chapter 2), and minimum wages (Chapter 3). The material used in this study will be drawn predominantly from the ILO Working Conditions Laws Database, which was most recently updated in 2011-2012 (see Box 1 below). Given that the information in the database covers a vast amount of legal information from over 150 countries, this report will focus on selected essential provisions. The framework for presenting the national legislative information in this publication is based on the structure of the relevant ILO Conventions and Recommendations for each subject, which is meant to help provide a simple method for presentation and comparison. This report builds upon previous editions produced in 2010 and 2008. The reports of 2008 and 2010, which used a similar framework to present the material, were based mainly on regions of the world. However, while the 2008 and 2010 reports disaggregated industrialised countries and CIS and Eastern European countries in Europe, for the 2012 edition a framework is adopted that better reflects the data contained in the Working Conditions Law Database and the working conditions legislation that exists in different regions of the world. Thus, while in the information in all other regions is ordered the same manner, the industrialised countries have been placed in the appropriate regions and the Eastern European countries have been classified with Europe and CIS countries

Exploring Kuwaiti mathematics: student-teachers' beliefs toward using Logo and mathematics education

The main objective of this study is to explore the effect of one taught course, a Logo module, on Kuwaiti elementary mathematics student-teachers’ beliefs about Information and Communication Technology (ICT) and Logo. The Logo module incorporated ICT, in particular the Logo programming language, as a cognitive tool, that supports the constructivist perspective for mathematics instruction. The Logo module comprised of 24-sessions (deducted from the hours of the Methods of Teaching Mathematics course) and was non-compulsory and non-credit bearing. It was developed and taught by the researcher during the Fall semester 2007 at the College of Basic Education in the State of Kuwait. The researcher was not employed by the College of Basic Education: his only relationship with the College was to conduct his research there. The intention of the module was to give student-teachers the opportunity to experiment with a powerful innovation in a practical mathematics instruction context, both as students and as teachers, thus, enable them to reflect on and reevaluate their beliefs about the nature of mathematics, the teaching and learning of mathematics, and using Logo as an ICT tool. The study explores how participation in the Logo module course may have influenced these beliefs and promoted more positive beliefs toward using ICT and in particular Logo programming language in their future mathematics classroom, and its potential to reform education and enhance students’ learning. The fact that Logo is not used yet in Kuwaiti schools for mathematics education is one of the drivers of this study

Numerical Simulation of Fully Grouted Rock Bolts

This chapter describes the application of numerical modelling to civil and mining projects, particularly rock bolting, developing a Final Element (FE) model for the bolt, grout, rock, and two interfaces under axial and lateral loading, verifying the model, analysing the stress and strains developed in the bolt and surrounding materials. Numerical methods are the most versatile computational methods for various engineering disciplines because a structure is discritised into small elements and the constitutive equations that describe the individual elements and their interactions are constructed. Finally, these numerous equations are solved together simultaneously using computers. The results from this procedure include the stress distribution and displacement pattern within a structure. Numerical modelling includes analytical techniques such as finite elements, boundary elements, distinct elements, and other numerical approaches that depend upon the material. The finite element method FEM is considered to evaluate the behaviour of materials and their interactions in a fully grouted bolt which is installed in a jointed rock mass. The simulations were carried out by ANSYS code
