Taschenbuch. Zustand: Neu. Neuware - Open and accountable government is one of the bedrock principles of our democracy. Yet, virtually since inauguration day, questions have been raised about the Bush Administration's commitment to this principle. News articles and reports by independent groups over the last four years have identified a growing series of instances where the Administration has sought to operate without public or congressional scrutiny. At the request of Rep. Henry A Waxman, this report is a comprehensive examination of secrecy in the Bush Administration. It analyses how the Administration has implemented each of our nation's major open government laws. The report finds that there has been a consistent pattern in the Administration's actions: laws that are designed to promote public access to information have been undermined, while laws that authorise the government to withhold information or to operate in secret have repeatedly been expanded. The cumulative result is an unprecedented assault on the principle of open government.

Taschenbuch. Zustand: Neu. Neuware - Immigration has always been a source of debate for the American public. During the early part of the 20th century Americans had concerns about the effects of European immigrants. Today similar concerns are being raised about Latin American immigrants. This book presents selected decennial census data on the foreign-born population of the United States from 1850 to 2000. This book provides the background knowledge necessary to examine the tables in a detailed and informed manner. The tables provide statistics that reveal all the trends in immigration during the last century of America's history. It is fully indexed.

Buch. Zustand: Neu. Neuware - Teaching is a profession which is so enormous and so packed with significance that the issues related to it have a consistently high ranking with members of society in virtually every public opinion poll. These issues include multicultural education, teacher training and accreditation, burn-out, teaching under conditions particular to a world-wide certain country, student behaviour and preparation, computers in the classroom, parental influence on the teaching process, the changing curriculum and its meaning for teaching, budgetary problems, and a multitude of similar issues. This book presents issues current to the field from educators and researchers from around the globe.

Buch. Zustand: Neu. Neuware - The acquired immunodeficiency syndrome (AIDS), is a disease of the body's immune system caused by the human immunodeficiency virus (HIV). AIDS is characterised by the death of CD4 cells (an important part of the body's immune system), which leaves the body vulnerable to life-threatening conditions such as infections and cancers. This book explores how this deadly virus has affected America and high-risk children, and presents reports on different forms of funding provided by the international and United States governments, and the fluctuating rates of AIDS cases.

Buch. Zustand: Neu. Neuware - This book presents fresh analyses of the burning issues in Afghanistan -- a country of ancient trade and commerce and modern foreign invasions and terrorism. At this time it is impossible to predict the probability of success of the Western military efforts to superimpose their version of a modern (and interdependent) country on the wildly independent and sometimes vicious clans roaming this desolate country.

Buch. Zustand: Neu. Neuware - In a world of seemingly never-ending technological advances, questions of ethics take on even more significance than in the past. Conflicts of interest abound and pressure mounts at every turn for more profits, higher incomes, power and instant gratification leads to the temptation to ignore questions of ethics. This book presents new and interesting research on ethical issues in the modern day.

Taschenbuch. Zustand: Neu. Neuware - The contents of this volume focuses on the relationship between passive smoking and cardiovascular pathology. Findings concerning the harmful effects of passive smoking, namely isolated or public exposure to someone else's smoking, began in the 1970's. This book reflects the current views on the relationship between cardiovascular pathology and passive smoking providing the main achievements obtained with the findings on the subject. The book presents the factors that influence negatively both a normal and diseased heart and blood vessels of non-smokers exposed to environmental smoking by means of different chapters structured with a sequence that begin from normal patterns until reaching the final step: irreversible damage of the heart and blood vessels.

Buch. Zustand: Neu. Neuware - North Korea is officially described as a socialist republic governed according to the ideology of Juche (loosely, 'self-reliance'). Kim Il-Sung, the founder of North Korea, was the country's first and only president; in the North Korean constitution he is described as the Eternal President of the Republic: 'The DPRK and the entire Korean people will uphold the great leader Comrade Kim Il-sung as the eternal President of the Republic.' The de facto head of state and government is Kim Jong-Il, who is Chairman of the National Defence Commission. The legislature of North Korea is the Supreme People's Assembly, or SPA; the current President of the SPA is Kim Yong Nam. The other senior government leader is the Premier, currently Pak Pong-ju. North Korea is a single-party state. The governing party is the Democratic Front for the Reunification of the Fatherland, a coalition made up of three smaller parties, the Workers Party of Korea, the Korean Social Democratic Party and the Chondoist Chongu Party. These parties nominate all candidates for office and hold all seats in the Supreme People's Assembly. North Korea seems to delight in its self-appointed role as an international trouble-maker, rogue state and budding nuclear power. Much of the world seems to regard it as a lose cannon -- but a potentially dangerous one rather than simply an irritating tiny, poverty-stricken, isolated country led by a short person with tall hair. This book focuses on the flurry of activities engaged in by North Korea.

Buch. Zustand: Neu. Neuware - An ecosystem is a complex of interconnected living organisms inhabiting a particular area or unit of space, together with their environment and all their interrelationships and relationships with the environment having a well-maintained ecological processes and interactions. It is characterised by the abundance of individual species populations; interspecies relationships; activity of organisms; physical and chemical characteristics of environment; flows of matter, energy, and information; and description of changes of these parameters with time. Hence, its surroundings can be categorised into physical and biological environment, which are self-defined, self-maintained and self-sustained dynamic natural systems. The physical environment comprises of lithosphere, hydrosphere and atmosphere, while the living beings in the biosphere constitute biological environment. The biosphere contains many delicate biological processes that have taken billions of years to evolve and there is a natural equilibrium for life sustaining processes dependent on relatively slow rates of recycling. These natural processes as well as resources are being over driven by human activities to meet the growing demands of the population. These developmental activities by humans ignoring the ecosystems and functional aspects are instrumental in bringing about irreversible changes in the ecosystem and their environment. The concern now is on the rise for the changes due to human induced activities that are proving detrimental, as it has exceeded the recycling rates of natural processes, which are altering the very nature of the environment. These changes are drastic, both to the environment and its inhabitants alike. Under such circumstances, it is necessary to do a retrospective analysis of the present situation to identify the degree of seriousness of different kinds of anthropogenic activities on the environment, plausible measures to curb further damaging to environment and better ways to live in harmony with the environment.

Buch. Zustand: Neu. Neuware - Business ethics is a form of the art of applied ethics that examines ethical rules and principles within a commercial context, the various moral or ethical problems that can arise in a business setting, and any special duties or obligations that apply to persons who are engaged in commerce. Business ethics can be both a normative and a descriptive discipline. As a corporate practice and a career specialisation, the field is primarily normative. In academia descriptive approaches are also taken. The range and quantity of business ethical issues reflects the degree to which business is perceived to be at odds with non-economic social values. Historically, interest in business ethics accelerated dramatically during the 1980s and 1990s, both within major corporations and within academia. For example, today most major corporate websites lay emphasis on commitment to promoting non-economic social values under a variety of headings (eg: ethics codes, social responsibility charters). In some cases, corporations have redefined their core values in the light of business ethical considerations (e.g. BP's 'beyond petroleum' environmental tilt). This book presents and discusses new and important issues in the field.

Buch. Zustand: Neu. Neuware - Photochemical reactions are the main class of chemical processes. These processes provide for life on Earth, since due to photochemical processes, plants absorb carbon oxide from the atmosphere changing them into the 'meal' for all creatures on Earth. Together with 'good' photochemical processes there are some 'bad' as well. This book is about photodestruction and light stabilisation and is devoted to these processes. For example, the heterochain polymers. They are the main class of large-tonnage polymers, which are used for manning a great variety of polymer and composite materials (including nanocomposites).

Buch. Zustand: Neu. Neuware - Breast cancer is a malignant tumour that has developed from cells of the breast. A malignant tumour is a group of cancer cells that may invade surrounding tissues or spread (metastasize) to distant areas of the body. The disease occurs almost entirely in women, but men can get it as well. The main types of breast cancer are ductal carcinoma in situ, invasive ductal carcinoma, lobular carcinoma in situ, invasive lobular carcinoma, medullary carcinoma, and Paget's disease of the nipple . About 1 of 8 women will get it in her lifetime. This book presents the latest research in this field.

Buch. Zustand: Neu. Neuware - Geothermal energy is a form of renewable energy derived from heat deep in the earth's crust. Enormous amounts of thermal energy are continuously generated by the decay of radioactive isotopes of underground rocks and stored in our globe's interior. This heat is as inexhaustible and renewable as solar energy. This heat is brought to the near-surface by thermal conduction and by intrusion into the earth's crust of molten magma originating from great depth. As groundwater is heated, geothermal energy is produced in the form of hot water and steam. The heated groundwater can be used for direct heating of homes and greenhouses, for vegetable drying, and for a number of other uses. These are known as direct uses of geothermal energy. Geothermal energy is also used for electricity production. This book presents leading-edge research in a field destined for increased attention throughout the world.

Buch. Zustand: Neu. Neuware - A fuel cell is an electrochemical energy conversion device. It produces electricity from external supplies of fuel (on the anode side) and oxidant (on the cathode side). These react in the presence of an electrolyte. Generally, the reactants flow in and reaction products flow out while the electrolyte remains in the cell. Fuel cells can operate virtually continuously as long as the necessary flows are maintained. Fuel cells differ from batteries in that they consume reactants, which must be replenished, while batteries store electrical energy chemically in a closed system. Additionally, while the electrodes within a battery react and change as a battery is charged or discharged, a fuel cell's electrodes are catalytic and relatively stable. Fuel cells are very useful as power sources in remote locations, such as spacecraft, remote weather stations, large parks, rural locations, and in certain military applications. A fuel cell system running on hydrogen can be compact, lightweight and has no major moving parts. Because fuel cells have no moving parts, and do not involve combustion, in ideal conditions they can achieve up to 99.9999% reliability. This equates to less than one minute of down time in a six year period. This book presents new leading-edge research in the field.

Buch. Zustand: Neu. Neuware - The environment is considered the surroundings in which an organism operates, including air, water, land, natural resources, flora, fauna, humans and their interrelation. It is this environment which is both so valuable, on the one hand, and so endangered on the other. And it is people which are by and large ruining the environment both for themselves and for all other organisms. This book reviews the latest research in this field which is vital for everyone.

Buch. Zustand: Neu. Neuware - Nanotechnology is a 'catch-all' description of activities at the level of atoms and molecules that have applications in the real world. A nanometre is a billionth of a metre, about 1/80,000 of the diameter of a human hair, or 10 times the diameter of a hydrogen atom. Nanotechnology is now used in precision engineering, new materials development as well as in electronics; electromechanical systems as well as mainstream biomedical applications in areas such as gene therapy, drug delivery and novel drug discovery techniques. This book presents the latest research in this frontier field.

Buch. Zustand: Neu. Neuware - In psychology, motivation refers to the initiation, direction, intensity and persistence of behaviour. Motivation is a temporal and dynamic state that should not be confused with personality or emotion. Motivation is having the desire and willingness to do something. A motivated person can be reaching for a long-term goal such as becoming a professional writer or a more short-term goal like learning how to spell a particular word. Personality invariably refers to more or less permanent characteristics of an individual's state of being (eg: shy, extrovert, conscientious). As opposed to motivation, emotion refers to temporal states that do not immediately link to behaviour (e.g., anger, grief, happiness). This book presents that latest research in this field.

Buch. Zustand: Neu. Neuware - Sleep apnea or sleep apnoea is a sleep disorder characterised by pauses in breathing during sleep. These episodes, called apneas (literally, 'without breath'), each last long enough so one or more breaths are missed, and occur repeatedly throughout sleep. There are two distinct forms of sleep apnea: Central and Obstructive. Breathing is interrupted by the lack of effort in Central Sleep Apnea, but from a physical block to airflow despite effort in Obstructive Sleep Apnea. In Mixed Sleep Apnea, both types of events occur. Regardless of type, the individual affected with sleep apnea is rarely (if ever) aware of having difficulty breathing, even upon awakening. Sleep apnea is recognised as a problem by others witnessing the individual during episodes, or is suspected because of its effects on the body. This volume offers new and valuable research developments.

Buch. Zustand: Neu. Neuware - Deoxyribonucleic acid (DNA) is a chemical found primarily in the nucleus of cells. DNA is a long, spiralling molecule that orchestrates the cell's daily operations and provides the genetic blueprint for the physical characteristics of all living organisms. It is the molecule that encodes genetic information in the nucleus of cells. It determines the structure, function and behaviour of the cell. DNA is made up of two complementary strands, the strands intertwine like a spiral staircase to form a structure called a double helix. Subunits, called bases, are the rungs of the staircase. The four nucleotides in DNA contain the bases: adenine (A), guanine (G), cytosine (C), and thymine (T). This volume presents the latest research from around the world.

Buch. Zustand: Neu. Neuware - Vitamin A is a generic term for a large number of related compounds. Retinol (an alcohol) and retinal (an aldehyde) are often referred to as preformed vitamin A. Retinal can be converted by the body to retinoic acid, the form of vitamin A known to affect gene transcription. Retinol, retinal, retinoic acid, and related compounds are known as retinoids. Beta-carotene and other carotenoids that can be converted by the body into retinol are referred to as provitamin A carotenoids. Hundreds of different carotenoids are synthesised by plants, but only about 10 % of them are provitamin A carotenoids. This book presents important new research in the field.

Buch. Zustand: Neu. Neuware - In psychology, motivation refers to the initiation, direction, intensity and persistence of behaviour (Geen, 1995). Motivation is a temporal and dynamic state that should not be confused with personality or emotion. Motivation is having the desire and willingness to do something. A motivated person can be reaching for a long-term goal such as becoming a professional writer or a more short-term goal like learning how to spell a particular word. Personality invariably refers to more or less permanent characteristics of an individual's state of being (e.g., shy, extrovert, conscientious). As opposed to motivation, emotion refers to temporal states that do not immediately link to behaviour (e.g., anger, grief, happiness). This important book is dedicated to motivation of health behaviours.
