Abstract

The decline of Trade Unionism in the UK in the 1980s has been well documented. Union density down from 53% in 1979 to 38% in 1980. The proportion of private sector plants with recognised Trade Unions down by 10 percentage points. Progressive legislative changes have outlawed closed shop arrangements resulting in a dramatic decline in such relationships by 1990. Following on from evidence provided by a survey into changing union presence in the 1980s (see Gregg and Yates, 1991), NIESR in conjunction with the LBS has undertaken a major new survey of the impact of the recession on company behaviour. This will include basic questions on union presence and institutions and pay setting systems (including pay freezes).

Abstract

Purpose

This study aims (1) to numerically investigate the characteristics of a human cough jet in a quiescent environment, such as the variation with time of the velocity field, streamwise jet penetration and maximum jet width. Two different turbulence modelling approaches, the unsteady Reynolds-averaged Navier–Stokes (URANS) and large eddy simulation (LES), are used for comparison purposes. (2) To validate the numerical results with the experimental data.

Design/methodology/approach

Two different approaches, the URANS and LES, are used to simulate a human cough jet flow. The numerical results for the velocity magnitude contours and the spatial average of the two-dimensional velocity magnitude over the corresponding particle image velocimetry (PIV) field of view are compared with the relevant PIV measurements. Similarly, the numerical results for the streamwise velocity component at the hot-wire probe location are compared with the hot-wire anemometry (HWA) measurements. Furthermore, the numerical results for the streamwise jet penetration are compared with the data from the previous experimental work.

Findings

Based on the comparison with the URANS approach and the experimental data, the LES approach can predict the temporal development of a human cough jet reasonably well. In addition, the maximum width of the cough jet is found to grow practically linearly with time in the far-field, interrupted-jet stage, while the corresponding axial distance from the mouth of the jet front increases with time in an approximately quadratic manner.

Originality/value

Currently, no numerical study of human cough flow has been conducted using the LES approach due to the following challenges: (1) the computational cost is much higher than that of the URANS approach; (2) it is difficult to specify the turbulent fluctuations at the mouth for the cough jet properly; (3) it is necessary to define the appropriate conditions for the droplets to obtain statistically valid results. Therefore, this work fills this research gap.

Abstract

Purpose

The purpose of this monograph is to present the first English translation of a unique French colonial report on women living under colonial rule in West Africa.

Design/methodology/approach

The issue begins with a discussion of the contribution this report makes to the history of social development policy in Africa, and how it serves the on‐going critique of colonisation. This is followed by the English translation of the original report held in the National Archives of Senegal. The translation is accompanied by explanatory notes, translator’s comments, a glossary of African and technical terms, and a bibliography.

Findings

The discussion highlights contemporary social development policies and practices which featured in identical or similar forms in French colonial social policy.

Practical implications

As the report demonstrates, access to basic education and improving maternal/infant health care have dominated the social development agenda for women in sub‐Saharan Africa for over a century, and will continue to do so in the foreseeable future in the Millennium Development Goals which define the international community’s agenda for social development to 2015. The parallels between colonial and post‐colonial social policies in Africa raise questions about the philosophical and cultural foundations of contemporary social development policy in Africa and the direction policy is following in the 21st century.

Originality/value

Though the discussion adopts a consciously postcolonial perspective, the report that follows presents a consciously colonial view of the “Other”. Given the parallels identified here between contemporary and colonial policy‐making, this can only add to the value of the document in exploring the values that underpin contemporary social development practice.
