Abstract:

Improvements to construction health and safety were driven by primary legislation promulgated in the 1970s and by subsequent regulations, codes and official guidance. In parallel social psychology, management and leadership theories were developing practical means for achieving health and safety objectives and reducing accidents and incidents of ill health. Despite the notable improvements that were achieved in countries with strong legislatives bases, the reduction in the rate of accidents has been significant but at the same time substantially falling short of providing safe and healthy work

Abstract:

Background: The physiological daily requirement for salt is low (1-2g) and most populations around the world are eating much more than this. Excess salt consumption progressively increases blood pressure levels throughout life, and this is one of the biggest contributors to cardiovascular diseases worldwide. The evidence in support of the adverse effect of salt on human health is very strong and widely accepted. Fortunately there is now increasingly firm evidence demonstrating the health benefits that can be achieved through salt reduction as well as broad consensus that, for most count

Abstract:

Optimum construction worker (CW) performance is required to achieve project delivery within project parameters. It is not always the case as CWs are regularly exposed to hazards, involved in accidents, their productivity is poor, they suffer from ill health, suffer from work-related musculoskeletal disorders (WMSDs) and contractors lack resources to allocate towards H&S. However, the lack or the absence of health and safety (H&S) measures, which the aforementioned depend on, has a negative impact on workers’ performance.

Abstract:

Background: Avian influenza is a serious infectious disease attracting great concerns of the world. It not only results in a huge economic loss but also poses a great threat to public health, and poultry production plays a major role of transmission as well as a locus of pathogen evolution, mutation and adaptation of avian influenza virus between wild birds and humans. Therefore, biosecurity measures along the poultry supply chains are important to prevent and control avian influenza. My objective was to summarize the past and present various measures against avian influenza in the industrial,

The prosperity of small micro and medium enterprises (SMME’s) in the construction industry is vital for the improvement of the South African economy. Unfortunately, the poor safety record of this industry negatively affects the sustainability of SMME’s and augments the loss of human lives. Owners and managers of SMME’s in the construction industry are usually financially fragile and unaware of the direct and an indirect cost associated with injuries that may result in potential profit loss and ultimately, bankruptcy.

Companies are expected to reduce the impact on society caused by its operations while at the same time, generate profit for its stakeholders. One way to satisfy both parts is by creating shared values. As the trend of servitization becomes more popular the ability of Product-Service Systems (PSS) to deliver additional value to customers arises. PSS provides an opportunity for developing a sustainable business model to benefit both the society and the stakeholders. A sustainable PSS can be based on the Triple Bottom Line dimensions, environment, economic, and social. Since the economic and envi

Abstract:

Health and safety issues have always been a major problem and concern in the construction industry. Wherever reliable records are available, construction is found to be one of the most dangerous on health and safety criteria, particularly in developing countries. Efforts have been made to address this problem, but the results have been far from satisfactory, as construction accidents continue to dominate the overall construction industry. Despite the programs implemented by government authorities and measures introduced by companies themselves, the number of construction accidents still remain

Abstract:

Mankind, and the development of people, exists due to risk-taking behaviour. It is not that humans should not take risks, but rather the ability to identify the magnitude of risk exposure in order that mankind‟s actions would be so selected as to mitigate exposed risk factors, that no harm should befall them. The approach to health and safety (H&S) has always been to manage H&S environmental factors that could have a negative impact on people, capital, and organisational systems. However, the critical component of human risk-taking behaviour that would have a far greater impact has rarely been

This is due to the fact that consumers tend to consume less red meat and more chicken and pork that are perceived to be healthier due to the negative publicity surrounding red meat and health. The nutritional emphasis is on leaner carcasses and an increase in the consumption of polyunsaturated fatty acids while reducing the ratio of n-6:n-3 polyunsaturated fats in the diet.

Abstract:

Introduction. Stone crushing in Dar-es-Salaam Tanzania is largely an informal occupational activity, with approximately 7000 workers exposed to varying level of respirable dust. A highly marginalized, self employed, informal stonecrusher is prone to multiple work related risks, particularly dust related respiratory diseases. Aim. This study, the first to be done among informal stone crushers in Southern Africa, aimed at determining the prevalence of dust related respiratory outcomes and relationships between these health endpoints and exposure to respirable dust in this sample of stonecrushers

Abstract:

Patent protection grants the patent holder with a market monopoly, free from market competition allowing the patentee to charge any price; therefore medicines are sold at prices much higher than the marginal cost of production and distribution. The connection between international trade and intellectual property has aggravated human rights and public health concerns surrounding the inaccessibility of essential medicines. The World Trade Organisation‘s Trade Related Aspects of Intellectual Property Rights (TRIPS) Agreement is an international instrument which has greatly impacted intellectual p

Abstract:

The study investigated the feasibility of including DPOAEs in the annual medical surveillance test battery for the identification of NIHL in a group of employees in a manufacturing industry in KwaZulu-Natal. Feasibility was investigated by exploring the sensitivity, specificity and predictive efficiency of DPOAEs, the ability of DPOAEs to detect subtle noise-induced cochlea changes, the test-retest reliability of DPOAEs and lastly, the duration of time taken to conduct the DPOAE test bilaterally. A cross-sectional and repeated measures within-in participant design was utilized in the study. A
