  • I do not know what prompted me to apply for the post of Primary Health Care Alcohol Liaison Worker and Counsellor with the Acorn Community Drug and Alcohol Service in Surrey, other than that it somehow felt right. I had not previously had experience of working with people with alcohol problems. It was late 1994 and I had recently left my job as a Fundholding Manager at a GP surgery in Guildford, having earlier completed my diploma training in person-centred counselling and psychotherapy.

  • Life cycle analysis, examining all stages in using a re- source, is central to the full cost accounting needed to guide public policy and private investment. A previous study examined the life cycle stages of oil, but without systematic quantification. 24 This pa- per is intended to advance understanding of the measurable, quantifiable, and qualitative costs of coal. In order to rigorously examine these different damage endpoints, we examined the many stages in the life cycle of coal, using a framework of en- vironmental externalities, or “hidden costs.

  • Soil communities are important aspects of biodiversity and they are involved in many important ecosystem processes, particularly nutrient cycling. Soil chemistry is neither an aspect of biodiversity nor one of the primary causes of change addressed by this project. Nevertheless, understanding mechanisms of change and correctly attributing effects to causes are central to the project, making it necessary to understand the soil chemistry at sites.

  • Our planet’s atmosphere is thought to have changed gradually and over a very wide range of CO2 concentrations throughout history. From ancient atmospheric gases trapped in ice bubbles, we have strong evidence indicating that atmospheric CO2 values reached minimum concentrations of approximately 180 parts per million during the Last Glacial Maximum, which was only 15,000 years ago. At the other extreme, calculations suggest that some 500 million years ago the atmospheric CO2 concentrations may have been about 4000 to 5000 parts per million....

  • The main objectives of this study were to examine the effects of coastal eutrophication on fi sh communities, and on local recreational fi shery and commercial pikeperch fi shery on the northern coast of the Gulf of Finland. The study focused on freshwater species, as they live their entire life cycle in the most eutrophied areas, i.e., the archipelago and inner bays. Freshwater species are important for the very popular recreational fi shery, forming the bulk of the annual total catch.

  • Impoverishing the local resource base can impoverish wider areas: deforestation by highland farmers causes flooding on lowland farms; factory pollution robs local fishermen of their catch. Such grim local cycles now operate nationally and regionally. Dryland degradation sends environmental refugees in their millions across national borders. Deforestation in Latin America and Asia is causing more floods, and more destructive floods, in downhill, downstream nations. Acid precipitation and nuclear fallout have spread across the borders of Europe.

  • HE ADDISON-WESLEY SERIES on Organization Development is legendary in the Organizational Development field and the basis for the change field. Its impact on the field of OD, and on the authors in particular, was and still is profound. This new Jossey-Bass Series is the 21st-Century version of the original theory and practice series. The three editors of the earlier books were Edgar Schein, Warren Bennis, and the late Richard Beckhard—true pioneers, founders, and “godfathers” of the field.

  • The taxanes include paclitaxel and docetaxel. These agents differ from the vinca alkaloids in that the taxanes stabilize microtubules against depolymerization. The "stabilized" microtubules function abnormally and are not able to undergo the normal dynamic changes of microtubule structure and function necessary for cell cycle completion. Taxanes are among the most broadly active antineoplastic agents for use in solid tumors, with evidence of activity in ovarian cancer, breast cancer, Kaposi's sarcoma, and lung tumors.

  • The rapid pace of change in the regulation of building energy performance has already created tremendous problems for the construction industry and the proposed acceleration of regulatory change towards zero carbon new buildings by 2020 will only widen the gulf between ambitious Government policy and the ability of the industry to deliver. The need for a radical overhaul in education and practice in the construction industry is urgent and undeniable.

  • The study of how biodiversity is spread around the world is known as bio- geography. Mite harvestmen illustrate one of the most common patterns in bio- geography, called vicariance: species become separated from each other when geographical barriers emerge. Those barriers can be formed by oceans, as in the case of the mite harvestmen; they can also be separated by rising mountains, spreading deserts, and shifting rivers. The other major pattern in biogeography, known as dispersal, occurs when species themselves spread away from their place of origin.

  • This document should be of interest to a broad audience interested in reducing greenhouse gas (GHG) emissions to the atmosphere. It was developed for regulatory organizations, project developers, and national and state policymakers to increase awareness of existing and developing monitoring, verification, and accounting (MVA) techniques. Carbon dioxide (CO2) sinks are a natural part of the carbon cycle; however, natural terrestrial sinks are not sufficient to absorb all the CO2 emitted to the atmosphere each year.

  • In response to climate change, many countries are likely to invest in even more infrastructure for coastal defenses and flood control to reduce the vulnerability of human settlements to climate change. Increased water shortages will increase demand for new irrigation facilities and new reservoirs. Similarly, natural ecosystems can reduce vulnerability to natural hazards and extreme climatic events and complement, or substitute for, more expensive infrastructure investments to protect coastal and riverine settlements.

  • A woman's hormone balance plays a part in most endometrial cancers. Many of the risk factors for endometrial cancer affect estrogen levels. Before change of life, the ovaries are the main source of the 2 main types of female hormones -- estrogen and progesterone. The balance between these hormones changes during a woman's menstrual cycle each month. A shift in the balance of these 2 hormones toward more estrogen increases a woman's risk for getting endometrial cancer.

  • This section explores the effect of CEO compensation on firm risk. We have noted in Section I that the effect of an increase in firm risk on CEO’s wealth depends on how much of this wealth comes from stock options relative to other forms of compensation such as salary and stock holdings. For a CEO who cares about percentage changes in wealth rather than absolute changes in wealth, we can measure this effect through the total CEO wealth elasticity with respect to stock volatility.

  • In many cases, young women and girls are not treated equally to young men and boys. We know that family values and gender roles are inherited from our forefathers and foremothers and that cultural environments also influence gender dynamics. I understand that I have the ability and that I am empowered enough to break this cycle. It is my responsibility to remember this when I become a mother. Everything depends on the will of communities to accept this kind of change and most of the time young people are more open to change....

  • All the necessary information and data were collected from both medical records of the patients and special questionnaires that were designed by our staff in 1996 for this purpose. Statistical analysis was carried out descriptively by using frequency and percentage. Presence of TB in the patients was confirmed by identifying the microorganism in the tissues detecting pathological changes in favour of TB and/or having past history of pulmonary TB associated with its anatomical complications such as cavitation, bronchiectasis, and bronchial stenosis.

  • The tumor suppressor p16 INK4a has functions beyond cell-cycle control via cyclin-dependent kinases. A coordinated remodeling ofN- and O-glycosyla-tion, and an increase in the presentation of the endogenous lectin galectin-1 sensing these changes on the surface of p16 INK4a -expressing pancreatic carcinoma cells (Capan-1), lead to potent pro-anoikis signals.
