Jigsaw: investigative analysis on text document collections through visualization

This article describes the Jigsaw system for helping investigative analysis across collections of text documents. Jigsaw provides multiple visualizations of the documents and the entities within them to help investigators discern embedded stories and plots. Our early focus within Jigsaw has not been on legal documents and E-discovery, but we feel that the system may have potential in these areas as well. This article illustrates Jigsaw’s views and operations using Enron email archives as example documents

International Outsourcing and the Skill Structure of Labour Demand in the United Kingdom

This paper investigates empirically the link between international outsourcing and the skill structure of labour demand in the United Kingdom. It is the first detailed study of this issue for the UK. Outsourcing is calculated using import-use matrices of input-output tables for manufacturing industries for the period 1982 to 1996. Estimating a system of variable factor demands, our main results show that international outsourcing has had a strong negative impact on the demand for unskilled labour. Hence, international outsourcing is an important component in explanations of the changing skill structure of manufacturing industries in the United Kingdom.Outsourcing; Fragmentation; Trade; Wages; Skill-biased technological change

Analysis of Influence of Heat Transfer Conditions on the Upper Cover to Heat Transfer in Thermosyphon

Numerical analysis of thermal conditions of a two-phase closed thermosyphon using the software package ANSYS FLUENT has been carried out. Temperature distributions at various heat transfer conditions on upper cover and different heat flow on bottom cover of thermosyphon have been obtained

International fragmentation and relative wages in the UK

This paper re-examines the trade-based explanation of increased wage inequality in developed countries by focusing on international outsourcing. It is the first detailed study to address the effects of outsourcing on labour markets in the UK. In a recent paper, Feenstra and Hanson (1996) estimate the effect of international outsourcing on wage inequality in the US. This paper extends the FH approach by using more detailed definitions of outsourcing and skill. The analysis applies to UK manufacturing over the period 1982-1997. Extending the analysis to the 1990s is considered to be crucial as outsourcing is predominantly a phenomenon of the 1990s. The econometric results suggest that technical change, import penetration and outsourcing all play an important role in explaining UK wage inequality. Outsourcing may account for about half of the increase in domestic wage inequality

International fragmentation and relative wages in the UK

While growing wage inequality is of ongoing concern in many developed countries, there still does not exist a consensus on the predominant source of this trend. Some argue that skill-biased technological change is responsible for the shift in the relative demand of skilled workers while others hold increased import competition from low-wage countries reducing employment for the unskilled responsible for the growing income divide within countries. This paper re-examines the trade-based explanation by focussing on international outsourcing. In a recent paper, Feenstra and Hanson (1996) estimate the effect of international outsourcing on wage inequality in the US. This paper extends the FH approach using more detailed definitions of import penetration and outsourcing as well as data for UK manufacturing industries for the period 1982-1996. The econometric results suggest that technical change and import penetration matter for wage inequality (although the effect of the latter depends crucially on whether or not estimations are weighted) while the role of outsourcing cannot be clearly determined
