This study is focussed on public and private sector The study is confined to industrial Public companies in the states of Kerala and Orissa along with companies in India. undertakings only. sector and private sector private sector companies in other states were studied. Even though the original plan of 190 companies as the sample size could not be accomplished, as the responses were very poor, but data could be collected frmn 6 public and 5 private sector companies in Kerala, 8 public and 8 private sector companies in Orissa along with 27 private sector companies in other states totalling to 54 companies. The number of years of data collected varies from 2 years to 6 years. Factors which are affecting capital expenditures and hence leading to the performance of private sector compared to public sector companies are studied. After the study and analysis, comparisons are made between public sector and private sector, and suitable recomendations are made so that public sector industries can also perform equally well as the private sector industries in India.

This document examines the time-series properties of the wage differentials that arise between the public and private sector in Colombia during the sample period 1984 to 2005. We Find conflicting results in unit-root and stationary tests when looking at wage differentials at an aggregate level (such as for men, women or both). However, when we analyse wage differentials at higher levels of disaggregation, treat them jointly as a panel of data, and allow for the presence of potential cross section dependence, there is more supportive evidence for the view that wage differentials are stationary. This implies that although wage differentials do exist, they have not been consistently increasing (or decreasing) over time.

Road transport and shipping are copious sources of aerosols, which exert a 9 significant radiative forcing, compared to, for example, the CO2 emitted by these sectors. An 10 advanced atmospheric general circulation model, coupled to a mixed-layer ocean, is used to 11 calculate the climate response to the direct radiative forcing from such aerosols. The cases 12 considered include imposed distributions of black carbon and sulphate aerosols from road 13 transport, and sulphate aerosols from shipping; these are compared to the climate response 14 due to CO2 increases. The difficulties in calculating the climate response due to small 15 forcings are discussed, as the actual forcings have to be scaled by large amounts to enable a 16 climate response to be easily detected. Despite the much greater geographical inhomogeneity 17 in the sulphate forcing, the patterns of zonal and annual-mean surface temperature response 18 (although opposite in sign) closely resembles that resulting from homogeneous changes in 19 CO2. The surface temperature response to black carbon aerosols from road transport is shown 20 to be notably non-linear in scaling applied, probably due to the semi-direct response of clouds 21 to these aerosols. For the aerosol forcings considered here, the most widespread method of 22 calculating radiative forcing significantly overestimates their effect, relative to CO2, 23 compared to surface temperature changes calculated using the climate model.

GPS technology has been embedded into portable, low-cost electronic devices nowadays to track the movements of mobile objects. This implication has greatly impacted the transportation field by creating a novel and rich source of traffic data on the road network. Although the promise offered by GPS devices to overcome problems like underreporting, respondent fatigue, inaccuracies and other human errors in data collection is significant; the technology is still relatively new that it raises many issues for potential users. These issues tend to revolve around the following areas: reliability, data processing and the related application. This thesis aims to study the GPS tracking form the methodological, technical and practical aspects. It first evaluates the reliability of GPS based traffic data based on data from an experiment containing three different traffic modes (car, bike and bus) traveling along the road network. It then outline the general procedure for processing GPS tracking data and discuss related issues that are uncovered by using real-world GPS tracking data of 316 cars. Thirdly, it investigates the influence of road network density in finding optimal location for enhancing travel efficiency and decreasing travel cost. The results show that the geographical positioning is reliable. Velocity is slightly underestimated, whereas altitude measurements are unreliable.Post processing techniques with auxiliary information is found necessary and important when solving the inaccuracy of GPS data. The densities of the road network influence the finding of optimal locations. The influence will stabilize at a certain level and do not deteriorate when the node density is higher.

Life-cycle assessment (LCA) is a technique that is used worldwide by clients and their design team to assess the impact of
their projects on the environment. The main advantage of LCA is in supporting decision making with quantitative data. LCA inventories
can be either fully developed or streamlined. Fully developed LCAs are time-consuming and costly to prepare. Streamlined LCAs can be
used as an effective decision-making tool when considering environmental performance during the design process, but with a loss of
inventory completeness. Acknowledging the advantages and disadvantages of both types of LCA, this paper proposes a hybrid LCA
method that uses input-output data to fill in those gaps routinely left in conventional LCA inventories.

This paper captures development of the GDAL as understood by its instigators as a platform for reform. The GDAL would respond to the challenge being put before education and training providers to prepare young people to create and engage with a learning society through their capacity for lifelong learning. These teacher education students would, ideally, bring skills and knowledge already gained in a professional career. While they would gain teacher registration they were better conceptualized as professional educators for an emerging post compulsory education, training and employment sector: it was expected that graduates would not only teach in schools but would also move readily within the network of learning spaces that young people increasingly experience in their formal education. In the process, they would be a force for change, seeding reform within secondary schools. As a 'teacher' these graduates would have the credibility to challenge the entrenched practices of other teachers. It is the story of 'what happened' as a consequence of this specific aim that I am telling today.

Government policy in Australia is increasingly encouraging training organisations in the Vocational Education and Training (VET) sector to adopt flexible delivery approaches, but some researchers are sounding a note of caution. Evidence is emerging that Australian VET learners are not universally ready for flexible delivery, and this is reflected in high attrition rates and low pass rates. The literature on flexible delivery identifies a number of specific factors that can impact on the success of adult learners. However, there seems to be agreement that failure or dropout is not determined by a single factor, but by the interaction of a number of factors that build up over time. To understand these factors, we need to understand the learners - what their participation in education means to them, the context in which they are studying, and the numerous inter-connected factors that contribute to their failure to achieve a successful outcome. This paper discusses four case studies from a research project that followed up a small number of adult learners who enrolled in flexible delivery VET courses but did not achieve a successful outcome.

This study examines the current status of cross-cultural management (CCM) in Australia.

The study is based on Reyes' (2004) Ph.D research of a qualitative nature in five organisations in the public and private sectors selected from a sample of organisations which appear to lead the field in Australia in respect of CCM. Literature is also surveyed to present a picture of the current legal and institutional setting of CCM in Australia and provide a context for the study.

Analysis of the findings highlights the gap between cross-cultural rhetoric and action in workplace situations. Problems are identified leading to incomplete and inadequate implementation of CCM in the respondent organisations. The study argues for the need for management to take a systems approach to the formulation and implementation of CCM. Some suggestions are made for improvements in the future.

Government policy in Australia is increasingly encouraging training organisations in the Vocational Education and Training (VET) sector to adopt flexible delivery approaches. This policy shift is supported by key VET stakeholders including Industry Training Advisory Boards. A recurring theme in VET policy documents is an apparent confidence that flexible delivery can meet the diverse needs of individual learners while at the same time providing cost savings. Yet evidence is emerging that Australian VET learners are not typically ready for flexible delivery, and this lack of readiness is reflected in high attrition rates and low pass rates in many flexibly delivered courses. One research project found that over 70% of learners in the Australian VET sector do not have the learning capabilities required to be ready for flexible delivery. A recent review of the module outcomes achieved by VET students nationally found that students studying by external/correspondence and self-paced unscheduled modes had lower module completion rates than students studying by other delivery strategies.

Research on student progress in flexible delivery within the Australian VET sector has largely been quantitative. That research provides useful statistical data on completion and attrition rates for various modes of delivery, but does not explore the reasons underlying the high attrition rates found in flexible delivery. The qualitative research that is available tends to focus on students who successfully complete their courses, not on those who withdraw. As a result, the Australian literature on flexible delivery in the VET sector is lacking in-depth qualitative information about students who enrol in courses but do not complete. In comparison, the broader literature on distance education and flexible delivery in other educational sectors offers some useful insights into student attrition, and can be can be used to inform research into attrition within the Australian VET sector.

This paper reports on aspects of a research project that followed up six adult learners who enrolled in VET courses but who either failed assessment or withdrew. The research project presented the students’ stories in the form of narrative case studies, focussing on the detailed examination of the barriers that each student experienced, and analysing these barriers in relation to issues raised in the literature. This paper reports on two particular themes that emerged from that research project. The literature on distance education and flexible delivery argues that:


· student dropout is often not determined by a single factor, but by the interaction of a number of factors that build up over time;

· students who experience difficulties when studying by flexible delivery can often be reluctant to access the support that is available to them.

This paper uses these themes as a point of reference in presenting the stories of some of the students who participated in the research project.
