International Research Project on Job Retention and Return to Work Strategies for Disabled Workers: Germany

[Excerpt] The International Research Project on Job Retention and Return to Work Strategies for Disabled Workers is an initiative of the International Labour Organisation (ILO) and the Global Applied Research and Information Network on Employment and Training (GLADNET). It reflects ILO and GLADNET joint aims of establishing a base for cross-national research and strengthening links between research analysis and policy reform in the field of employment of disabled people. The Project is a response to a combination of developments which highlight the need for more effective policies and practices in support of workers whose prospects of remaining in employment are jeopardised by work injury, illness or disability. Persons with disabilities are increasingly claiming rights to stay in work as well as to access employment. Pressures on state budgets, the rising costs of compensation claims and disability benefits, and changes in the structure of the labour market are strengthening policies in favour of job retention and return to work. Enterprises are developing their own strategies to minimise the costs of disability and to retain valued employees. Overall, the balance of responsibility is shifting from the state to the enterprise. Policies and practices to prevent disabled workers from leaving work unnecessarily, and to facilitate rapid return to employment if job loss cannot be prevented, are recent developments in many countries. The cross-national exchange of information on initiatives and their effects is limited. The first aim of this Project has been to gather information about what has been attempted, by whom, for what purposes, in which contexts and to what effects. The second, more ambitious, aim, is to examine the interaction between the various policies and practices, identify dysfunctions, and work towards more coherent and cost-effective strategies for job retention and return to work which might be applied in different national systems. The ultimate objective is to identify strategies which can be put into effect in the workplace

Efficient Decomposition of Dense Matrices over GF(2)

In this work we describe an efficient implementation of a hierarchy of algorithms for the decomposition of dense matrices over the field with two elements (GF(2)). Matrix decomposition is an essential building block for solving dense systems of linear and non-linear equations and thus much research has been devoted to improve the asymptotic complexity of such algorithms. In this work we discuss an implementation of both well-known and improved algorithms in the M4RI library. The focus of our discussion is on a new variant of the M4RI algorithm - denoted MMPF in this work -- which allows for considerable performance gains in practice when compared to the previously fastest implementation. We provide performance figures on x86_64 CPUs to demonstrate the viability of our approach

Stock Markets and Business Cycle Comovement in Germany before World War I: Evidence from Spectral Analysis

This paper examines the comovement of the stock market and of real activity in Germany before World War I under the effcient market hypothesis. We employ multivariate spectral analysis to compare rivaling national product estimates to stock market behavior in the frequency domain. Close comovement of one series with the stock market enables us to decide between various rivaling business cycle chronologies. We find that business cycle dates obtained from deflated national product series are severely distorted by interference with the implicit price deflator. Among the nominal series, the income estimate of Hoffmann (1965) correlates best with the stock market, while the tax based estimate of Hoffmann and Müller (1959) is too smooth especially before 1890. We find impressive comovement between the stock market and nominal wages, a sub-series of Hoffmann's income estimate. We can show that a substantial part of this nominal wage series is driven by data on real investment activity. Our findings confirm the traditional business cycle chronology for Germany of Burns and Mitchell (1946) and Spiethoff (1955), and lead us to discard later, rivaling business cycle chronologies.Business Cycle Chronology, Imperial Germany, Spectral Analysis, Effcient Market Hypothesis
