Development of new ecological footprint techniques applicable to consumer electronics

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.In order to extend ecological footprint analysis (EFA) to electronic products, new methods had to be developed which associate the world average bioproductive space per capita and year - the fair Earth share - with an individual product. The problem analysed in this thesis is the need for an environmental assessment tool for electronic products, which uses natural capital accounting. This need arose because so far, electronic products were mainly assessed using life cycle analysis with a focus on toxicity. Since the ecological footprint (EF) is a sustainability indicator, the sustainability discussion and in particular its relevance and implications with regard to the EF is reviewed. The electronic products assessed in this thesis are a personal computer (PC) in an exploratory study, and three mobile phones (two main case studies and one updated case study). To establish the land areas used by the mined materials used in electronic products, a database was developed based on site specific data found in the literature, and on approximations from the density of materials and their overburden. A life cycle energy approach was used to determine the burdens from producing and using a mobile phone. In order to estimate energy requirements for materials for which no data was available, the relationship between abundance and rucksack / overburden values was used in a regression analysis. Direct land use data and results from the energy analysis were used as an inventory for the subsequent EFA. An EF time series was applied to represent a more accurate picture of PC and phone use. This was also necessary since the EF reflects the instantaneous rate (a snapshot) of resource consumption. Key results are that the EF of electronic products are much larger than their actual size and that different electronic products have different EF. Our methodology proved sensitive enough to reveal differences even in small electronic products, given the high benchmark of a fair Earth share, and useful in monitoring space-efficient technology

Green Meetings - a factor of success for a conference and event management company?: The case of JPdL

In the 21st century, climate change and environmental catastrophes are a worldwide acknowl-edged problem, which requires international cooperation and effort from every individual. Therefore more and more businesses realized the urge of taking action and implemented a sus-tainability strategy into their business operations, so also the meeting and event industry. This thesis deals with the subject of environmental sustainability implemented into the meet-ing and event sector. So called “Green Meetings” are meetings, which are planned and executed in a way that causes the least negative impact on the environment. The goal of this thesis is to examine, the impact of a “Green Meeting Strategy” on the competitiveness and profitability of JPdL, a Canadian Conference and Event management company. The analysis provides the base-line for a concept developed for JPdL if they decide to implement a green meeting strategy

The Connection between Health Promotion, Prevention, and Psychosocial Health: An Innovative Action Model

The promotion of psychosocial health among individuals, groups, and society is becoming an increasingly important task and research topic in the field of public health. Psychosocial health is a complex interaction between the psyche of an individual and the social environment in which that individual lives. Promoting psychosocial health is often challenging and complex for health care professionals. Therefore, an important question of public health significance is: how can we address and improve the psychosocial health of individuals, groups, as well as society in general? An interdisciplinary team of specialists at the Department of Health Professions at the Bern University of Applied Sciences, Switzerland, focused on the connection between health promotion, prevention, and psychosocial health. This team newly defined these topics in relation to how they could be synergistically combined to promote psychosocial health. Additionally, they presented an action model to graphically depict their connection. The proposed action model is based upon already well-established concepts, models, frameworks in health promotion, and prevention practice. In a further step, they have depicted them in a way that clearly integrates and combines their core concepts for their practical application in promoting psychosocial health. As these topics are overlapping, their clear illustration is important in promoting their systematic and planned usage. This new and innovative approach encourages the systematic usage of health promotion and prevention for the promotion of psychosocial health. The next step would be the implementation and evaluation of this action model, especially the measurement of the outcome (psychosocial health). The integrative and intentional use of health promotion and prevention is an innovative approach for the promotion of psychosocial health in public health practice

Virulence, persistence and dissemination of Mycoplasma bovis

Bovine mycoplasmosis due to Mycoplasma bovis causes several important bovine diseases such as pneumonia, mastitis, arthritis, otitis, genital disorders or keratoconjunctivitis. Variable surface lipoproteins, adhesion, invasion of host cells, modulation of the host immune system, biofilm formation and the release of secondary metabolites like hydrogen peroxide, as well as synergistic infections with other bacterial or viral pathogens are among the more significantly studied characteristics of the bacterium. The aim of this review is to summarize the current knowledge regarding the virulence of M. bovis and additionally, factors contributing to the dissemination and persistence of this pathogen in the bovine host will be discussed
