It will describe the model’s development and outline its core clinical components. The practice of therapy will be described as well as recent developments within the model. Some key criticisms will be raised, followed by a case example which highlights the therapeutic focus of Bowen’s approach. This is the author’s version of the work. It is posted here by permission of Australian Academic Press for personal use, not for redistribution. The definitive version was published in Australian and New Zealand Journal of Family Therapy (ANZJFT) Vol.20 No.2 1999 pp 94-103). Introduction Murray Bowen's family systems theory (shortened to 'Bowen theory' from 1974) was one of the first comprehensive theories of family systems functioning (Bowen, 1966, 1978, Kerr and Bowen, 1988). While it has received sporadic attention in Australia and New Zealand, it continues to be a central influence in the practice of family therapy in North America. It is possible that some local family therapists have been influenced by many of Bowen's ideas without the connection being articulated. For example, the writing of Guerin...

...www.asbiology101.wordpress.com An introduction to the microscope and magnification MAGNIFICATION AND RESOLUTION Because cells are too small to be seen with the naked eye, the light microscope was developed to produce enlarged and more detailed images of cells. The magnification of an image is how much bigger it appears under the microscope than it is in real life, and is worked out using the following formula: magnification = image size ÷ actual size unit metre decimetre centimetre millimetre micrometre nanometre picometre symbol m dm cm mm μm nm pm metres 1 0.1 0.01 0.001 0.000 001 0.000 000 001 0.000 000 000 01 However, magnification on its own does not increase the level of detail seen, it just increases the size. The term resolution refers to the ability to see two distinct points separately. For example, if the resolution of a light microscope is 200nm (0.2μm), this means it can see any two different points as separate objects if they are 200nm apart or more; but if they are any closer than this amount, they appear as one object. THE LIGHT MICROSCOPE Light microscopes use a number of lenses to produce an image that can be viewed directly at the eyepiece. Light passes from a bulb under the stage, through a condenser lens and then through the specimen. This beam of light is passed through an objective lens and then the eyepiece lens. The light microscope usually has a number of objective lenses which can be rotated into position...

The consequences should be absent if the hypothesis is not correct. Conclusion: Formulate the simplest general rule that organizes the hypothesis, predicted effects, and experimental findings. What is the principle of falsifiability? For a hypothesis to be considered scientific it must be testable?it must, in principle, be capable of being proven wrong. Fact: A phenomenon about which competent observers can agree. Theory: A synthesis of a large body of information that encompasses well-tested hypotheses about certain aspects of the natural world. Law: A general hypothesis or statement about the relationship of natural quantities that has been tested over and over again and has not been contradicted. Also known as a principle. Evidence: which serves to either support or counter a scientific theory or hypothesis. Experiment: is a test carried out in order to discover whether a theory is correct or what the results of a particular course of action would be . What did Galileo do to challenge Aristotle?s belief that heavy objects fall faster than lighter objects? Galileo very carefully examined Aristotle?s hypothesis. Then he...

...largely structural improvements, such as more instructional time, minimum course requirements for high school diplomas, and an emphasis on local planning efforts to promote efficiency and effectiveness. The desire to improve student achievement was there, but the focus on content-that is, a comprehensive, specific vision of what students actually needed to know and be able to do-was lacking. Standards are a bold initiative. Through content standards in the core subjects, California began to redefine the state’s role in public education. For the first time, the knowledge and skills that students needed to acquire were explicitly stated for the most part by grade level, although science standards at the high school level were organized by discipline. The standards are rigorous. Students who master this content are on a par with those in the best educational systems in other states and nations. The content is attainable by all students, given sufficient time, except for those few who have severe disabilities. We continue to regard the standards as firm but not unyielding; they will be modified in future years to reflect new research and scholarship. Standards describe what to teach, not how to teach it. Standards-based education maintains California’s tradition of respect for local control of schools. To help students achieve at high levels, local...

...Chapter 2 ENERGY CONVERSION AND GENERAL ENERGY ANALYSIS W hether we realize it or not, energy is an important part of most aspects of daily life. The quality of life, and even its sustenance, depends on the availability of energy. Therefore, it is important to have a good understanding of the sources of energy, the conversion of energy from one form to another, and the ramifications of these conversions. Energy exists in numerous forms such as thermal, mechanical, electric, chemical, and nuclear. Even mass can be considered a form of energy. Energy can be transferred to or from a closed system (a fixed mass) in two distinct forms: heat and work. For control volumes, energy can also be transferred by mass flow. An energy transfer to or from a closed system is heat if it is caused by a temperature difference. Otherwise it is work, and it is caused by a force acting through a distance. We start this chapter with a discussion of various forms of energy and energy transfer by heat. We then introduce various forms of work and discuss energy transfer by work. We continue with developing a general intuitive expression for the first law of thermodynamics, also known as the conservation of energy principle, which is one of the most fundamental principles in nature, and we then demonstrate its use. Finally, we discuss the efficiencies of some familiar energy conversion processes, and examine the impact on energy conversion on the environment. Detailed treatments...

...Answers to Conceptual Integrated Science End-of-Chapter Questions Chapter 1: About Science Answers to Chapter 1 Review Questions 1 The era of modern science in the 16th century was launched when Galileo Galilei revived the Copernican view of the heliocentric universe, using experiments to study nature’s behavior. 2 In Conceptual Integrated Science, we believe that focusing on math too early is a poor substitute forconcepts. 3 We mean that it must be capable of being proved wrong. 4 Nonscientific hypotheses may be perfectly reasonable; they are nonscientific only because they are not falsifiable—there is no test for possible wrongness. 5 Galileo showed the falseness of Aristotle’s claim with a single experiment—dropping heavy and lightobjects from the Leaning Tower of Pisa. 6 A scientific fact is something that competent observers can observe and agree to be true; a hypothesis is an explanation or answer that is capable of being proved wrong; a law is a hypothesis that has been tested over and over and not contradicted; a theory is a synthesis of facts and well-tested hypotheses. 7 In everyday speech, a theory is the same as a hypothesis—a statement that hasn’t been tested. 8 Theories grow stronger and more precise as they evolve to include new information. 9 The term supernatural literally means “above nature.” Science works within nature, not above it. 10 They rely on subjective personal experience and do not lead to testable hypotheses. They lie outside...

Copyright 2005 by the Natural Resources Defense Council. Natural Resources Defense Council issue paper Commercial Nuclear Power EXECUTIVE SUMMARY Because of the sheer magnitude and urgency of the global climate challenge, the United States must consider all forms of energy—as long as they do not otherwise undermine international and environmental security. Unfortunately, the nuclear power industry in its present state suffers from too many security, safety, and environmental exposure problems and excessive costs to qualify as a leading means to combat global warming pollution. Large-scale nuclear plants remain uneconomic to build. And while the nuclear fuel cycle emits little global warming pollution, nuclear power still poses globally significant risks that need to be further reduced, including:...

Isolated system * Boundary prevents the system from exchanging BOTH matter & energy with its surroundings. * Both matter and energy within the system are fixed & finite because none can enter and none can leave the system. * Imaginary – impossible for any real boundary to be so perfectly insulated that energy can neither enter or escape. 2. Closed system * Boundary permits the exchange of energy, but not matter within its surroundings * Matter within the system is finite but energy is exchangeable in and out of the system 3. Open system * Boundary permits exchange of both energy and matter * Ie.

...Association of Home Builders. organization website “www.nahb.com” Built Green- organization website “www.builtgreen.net” These “organizations” are organized around the idea that a group of individuals have found merit and acheivement in creating better building practices that benefit the environment and an owner’s built habitat. The individuals probably understood that creating an organization would benefit their agenda more efficiently and effectively than just a charter or group. The organizations then have the interest of their members. Their members have founded these organizations simply to provide better building practices, cleaner environment, more effecient energy use, and better overall quality life built directly from the green building elements. The National Association of Home Builders (NAHB) does not appear to have been started with the initial effort to create green building practices. This organization has been around longer than the green building movement began its’ roots, but has watched the trends of the housing market, evaluated the financial systems within this industry, and have forecast from these analysis. Provided, the NAHB has seen a growing interest in the community to create higher quality homes and businesses while also protecting the environment.
