The use of the cervicograph with the incorporated action and alert lines in labour management in developing country obstetrics is now well established and patients in labour in Port Moresby have been thus managed since 1973. In this study the cerviograph was introduced in hospitals and health centres in Enga Province and the results analysed. Despite intensive tuition in its use, a large number of cervicographs were incorrectly constructed, especially in health centres, and its introduction made little difference to operative delivery or perinatal mortality rates. The proportion of patients crossing the action line was much higher than in Post Moresby but this difference was probably also largely due to the inaccuracy of many cervicographs. It is likely that these difficulties will not be overcome until many more nurses with intensive training in the use of the cervicograph are available and until more deliveries take place ...

There has been growing international consensus on issues related to child labour - evident in various declarations, platforms, conventions, programmes of action etc. Child labour is the economic exploitation of children, or performance of any work that is likely to be hazardous or to interfere with the child's health or physical, mental, spiritual, moral or social development. Poverty is the principal cause of child labour. Mostly the children work to support their families and also for their own survival. Paradoxically, however, child labour further aggravates the poverty syndrome as it usually deprives the children of education and opportunity to acquire skills for developing earning potentials. Other causes of child labour include family indebtedness, the lack or poor quality of schooli...

High levels of unemployment are a permanent feature in the urban areas of many developing countries. South Africa is no exception in this regard. Poverty and hardship caused by unemployment force many participants in the labour market to venture into the urban informal economy in order to survive. The activities of the waste pickers fall within the urban informal economy. In spite of the fact that waste pickers are a common sight in the urban areas of Pretoria and other South African cities, remarkably little is known about them and scant attention is paid to them. The aim of the study was to establish a socio-economic profile of the street waste pickers in Pretoria and to describe the social interaction and relationship dynamics between the waste pickers and their families, each other, th...

This paper analyses the effectiveness of non-formal schools for working children in Jalandhar, Punjab, India, in mainstreaming child labourers into the formal education system through incentivised, informal schooling. Using a family fixed effects model and sibling data as an equivalent population comparison group, I find that the non-formal schools effectively provide an alternative to formal primary education and also show high success rates of mainstreaming and maintaining children into post-primary education relative to the control group. I find that the children within the non-formal schools are 40.47-50.07% more likely to still be studying relative to the sibling-inclusive control group, and have 1.976 to 3.389 years less of a gap in educational attainment. I conclude that the child l...

This work deals with a study on estimation of energy consumption in eight readily defined unit operations of cashew nut processing. Data for analysis were collected from nine cashew nut mills stratified into small, medium and large categories to represent different mechanization levels. Series of equations were developed to easily compute requirements of electricity, fuel and labour for each of the unit operations. The computation of energy use was done using spreadsheet program on Microsoft Excel. The results of application test of the equations show that the total energy intensity in the cashew nut mills varied between 0.21 and 1.161MJ/kg. Electrical energy intensity varied between 0.0052 and 0.029MJ/kg, while thermal energy intensity varied from 0.085 to 1.064MJ/kg. The two identified energy intensive operations in cashew nut processing are cashew nut drying and cashew nut roasting, altogether accounting for over 85% of the total energy ...

Using longitudinal data from Ukraine we examine the extent of any long-lasting effects of exposure to the Chernobyl disaster on the health and labour market performance of the adult workforce. Variation in the local area level of radiation fallout from the Chernobyl accident is considered as a random exogenous shock with which to try to establish its causal impact on poor health, labour force participation, hours worked and wages. There appears to be a significant positive association between local area-level radiation dosage and perception of poor health, though much weaker associations between local area-level dosage and other specific self-reported health conditions. There is also some evidence to suggest that those who lived in areas more exposed to Chernobyl-induced radiation have sig...

High angle conveyor systems in open pit mining offer many advantages over the traditional, truck only, haulage systems, including: (1) superior energy efficiency (2) less dependency on petroleum products (3) less sensitivity to inflation (4) less labour (5) less excavation for the amount of ore recovered, and (6) less ramp construction and maintenance costs. This paper presents the sandwich belt high angle conveyor as the vital link to optimisation of inpit conveying systems. High angle conveyor development to date is discussed, beginning with studies in 1979, to the first large scale prototype in 1983, through the numerous commercial installations. Discussion continues with the high angle conveyor systems to suit the various open pit mining operations and the corresponding characteristics of the system components, particularly the high angle conveyor. The range of high angle conveyor systems from the low capacity (up to 1 814 t/h), low lift ...

The paper seeks to illuminate everyday work practices in the economic spaces of Malaysia's business process outsourcing (BPO) industry. It draws upon empirical evidence from call centre staff and promotes analytical sensitivity to the experience of labour and spatiotemporal relations within the offshore back offices of multinational corporations located in Cyberjaya, Malaysia. The analysis provides an empirical snapshot of how IT-facilitated work practices in the global information economy are embedded and socially reproduced in everyday settings. To this end, the paper engages anthropologically with BPO labour, and critiques -globalist- representations of economic and social transformation frequently articulated through an abstract, dehumanized space of networks and flows often seen to wa...

This article reviews the little examined early work of the Greek Marxist and state theorist, Nicos Poulantzas (1936-1979). In his first book, Nature du choses et droit of 1965, the young scholar developed a sociology of law culled from the insights of philosophical ontology. The article sets out the central claims of that book and reflects on its place in Poulantzass intellectual development. Drawing on Heidegger, Sartre and Marx, Poulantzas proposed a species of Natural Law theory that unified `facts' and `values' by grounding legal concepts in a theory of social praxis centred on material labour. Legal categories were thus irreducible to ahistorical essences but were, rather, expressions of mankinds struggle to realize its intrinsic freedom. As we shall see, although flawed and in key re...

Abstract We provide the first firm-level evidence of the impact of the trade in producer services (-offshoring-) on the labour market. Using a new data set from the UK that measures trade in services at the firm level, we find no evidence that importing intermediate services is associated with job losses or greater worker turnover. Using regression to control for observable differences between firms that import service inputs and those that do not, we show that firms that start importing intermediate services experience faster employment growth than equivalent firms that do not. This seems likely to be the result of positive demand shocks, which cause a simultaneous increase in employment, output, and use of imported service inputs.

Radiation decontamination of dry ingredients, herbs and enzyme preparations is a technically feasible, economically viable and safe physical process. The procedure is direct, simple, requires no additives and is highly efficient. Its dose requirement is moderate. Radiation doses of 3-10 kGy (0.3-1 mrad) have proved sufficient to reduce the viable counts to a satisfactory level. Ionising radiations do not cause any significant rise in temperature. The flavour, texture or other important technological or sensory properties of most ingredients are not influenced at radiation doses necessary for satisfactory decontamination, and radiation obviates the chemical residue problem. The microflora surviving radiation decontamination of dry ingredients are more susceptible to subsequent antimicrobial treatments. Recontamination can be prevented as the product can be irradiated in its final packaging. Irradiation could be carried out in commercial containers and would result in considerable ...

The design of a gaging head for a portable radionuclide X-ray fluorescence analyzer is described. The gaging head is designed as a construction unit system which enables the application of lateral reflexion geometry as well as of coaxial geometry. It is designed so that adjustment from one geometry to the other is labour and time saving. The selection of characteristic radiation is performed by a couple of Ross' differential filters. These filters are prepared by a novel technique developed by our laboratory. The filter exchange is effected by the longitudinal move of the couple of filters encapsulated in a holder. The shift of the filters is controlled by means of a triggering mechanism situated in the body of the gaging head handle. This design makes is possible to handle the gaging head during measurements with one hand. A simple interchange of the absorption filter for the transmissive filter allows the operator to avoid any unwanted shift of the head during ...

Placental insufficiency, inducing hypoxia-ischaemia, is considered a major cause of neuronal injury and impaired post natal development. Placental insufficiency alters the metabolism of arachidonic acid and its oxidation products. Premature labour and low-birth-weight infants are associated with reduced intrauterine blood-flow and infections of the reproductive tract. Thyroidal activity is depressed in undernutrition (placental insufficiency). Premature infants require extra vitamin C for normal tyrosine metabolism (tyrosine is the thyroxine precursor). Among the symptoms indicating infantile cretinism, which appear during 3-5 months of age are: delayed union of skull bones, torpid behaviour, slow feeding, cyanosis during feeding, excessive sleepiness, enlarged tongue, umbilical herniation, flabby musculature, short stature and delayed development. These symptoms have all been described in low-birth-weight infants and sudden infant death syndrome victims by various ...

Exposure to crystalline silica dust causes multiple diseases, but silicosis and silica dust-associated tuberculosis (TB), in particular, are the two diseases that remain high on the list of occupational health priorities in low-income countries and that still occur in some high-income countries. The prevalence of silica-related TB is exacerbated by the human immunodeficiency virus (HIV) epidemic in low-income countries. This review describes the morphology of silica and the variable potency of the different forms. Sources of crystalline silica are discussed, with emphasis on less commonly recognised sources, such as small-scale mining operations and agriculture. Trends in the prevalence of silicosis are also presented. Although efforts have been made for many years in most countries to reduce silica dust levels, silicosis continues to occur even in young people. The clinical and pathological features and diagnosis of silicosis, with emphasis on chest radiography, are described. The ...

For large transmission steel towers to be built in a mountainous area, caisson type pile foundations are often applied. The works for construction of this kind of foundation are manned operations such as drilling, arranging reinforcements, concrete laying, etc. in a narrow vertical pit which is 3m in diameter and about 20m in depth, but securing labour force of good quality for such works becomes increasingly difficult. In order to cope with the above situation and achieve reduction of costs, shortening of construction period, improvement of safety, saving of manpower, etc. a power supply company and construction companies have developed jointly a method of unmanned construction in a caisson type pile foundation pit. This method consists of the use of a caisson type pile full size excavator (this consists of an excavator proper, a vacuum soil discharging device, a monitor/controller, a load crane and a reaction pad, and performs continuously unmanned operations in ...

The Canadian wind energy industry is experiencing rapid and unprecedented growth. The year 2006 saw the installation of 534 MW of wind energy across Canada, representing approximately $1 billion in new investment. It is anticipated that the wind energy industry will help to create jobs and training opportunities for many Canadians, as well as provide ongoing economic benefits to local communities through municipal tax and land lease payments. However, many challenges remain if Canada is to meet, or exceed, its objective of a total of 10,000 MW in installed wind energy by 2015. This conference provided a forum for wind industry member, academics and representatives of both governmental and non-governmental agencies to discuss issues related to wind energy development. The conference was divided into 3 streams. The policy stream examined issues related to the Canadian Wind Power Production Incentive (WPPI) program, as well as various federal policies regarding environmental assessments ...

Dimensional variability studies and published dimensional variability standards have been used by the foundry industry for years as an indicator of the casting process` ability to produce uniform parts. These studies are an extremely useful tool in the continuous ``dimensional dialogue`` between foundries and customers. The nature of these studies, and of the current tolerancing systems used by casting designers, leaves room for some misinterpretation and misuse of these study results. This paper contains two important discussions. The first part explains exactly what these studies represent. Following this is a brief explanation on dimensional and geometric tolerances and how they communicate dimensional requirements.

The costs used for the overhead line are actual numbers for a line scheduled to be built by a utility. The underground circuit costs were developed using the same criteria of line rating, contingencies, and location. Often cost comparisons between overhead and underground lines are made using figures taken from studies with widely varying assumptions. This project attempts to provide a comparison by studying the costs of overhead and underground lines following the same route and using the same design assumptions. Caution must be used, however, in extending the results of this study beyond its original intent. It is site-specific and may be representative of only one area of the country. 9 refs., 23 figs., 18 tabs.

Accurate engineering cost estimates are critical in developing bids for new work, and for effective resource allocation and project control. This study reports on design estimating methods found in the literature, and on the results of two empirical studies of how estimating techniques are used in professional practice and their accuracy. The study found great reliance on a classic {open_quotes}activity analysis{close_quotes} approach to estimating design resources, and significant hazards in commonly used parametric techniques. The study found that project managers expect their estimates to be accurate (with 80% confidence interval) of between -10% to +25%. The study also found that actual bids between engineering firms had a much greater range (-40% to +45%) than can be explained by accuracy. Perhaps most importantly the study found that none of the sampled ...
