Advanced Search Boolean Search Within all of the search fields, the Boolean Operators AND (also + or &), OR, and NOT (also -) allow you to perform searches that specify logical relationships between terms. By default, an AND relationship between each of the terms you enter is established except for the Author field (see Author Searching below). Author Searching To search for multiple authors, separate each author name with either AND or OR. Phrases To bypass the default use of the AND relationship between the terms you enter, wrap your terms in quotes. Wildcards Wildcards allow you to construct a query with approximate search terms. Stemming You can expand your search by enabling stemming. Enabling stemming will automatically include the root terms of the words you have used in your search. Narrow Your Search to Specific Journals If you want to search within specific journals, click on the "Modify Selection" button in the Journal Titles section. Save Your Search

Patterns in Flow-Based Programming (Apr., 2005) J. Paul Morrison In recent years, the concept of "pattern" seems to be have caught the imagination of many in the information technology (IT) industry. This concept was developed extensively by C. Alexander, first in his seminal book "Notes on the Synthesis of Form", and then later in "The Timeless Way of Building" and "A Pattern Language". Here is a quote from the 1994 book by the author of this paper, "Flow-Based Programming" (ISBN 0-442-01771-5): It is a truism that most businesses in the Western world would stop functioning if it were not for the efforts of tens of thousands, if not hundreds of thousands, of application programmers. The significant fact ... is that application programming in its present form really is hard and in fact has not progressed all that much since the days of the first computers. Flow-Based Programming (FBP) is a technology that addresses these fundamental problems by breaking away from the purely sequential, von Neumann architectural style.

Flat Earth The paradigm of a spherical Earth appeared in Greek philosophy with Pythagoras (6th century BC), although most Pre-Socratics retained the flat Earth model. Aristotle accepted the spherical shape of the Earth on empirical grounds around 330 BC, and knowledge of the spherical Earth gradually began to spread beyond the Hellenistic world from then on.[2][3][4][5] The modern misconception that educated Europeans at the time of Columbus believed in a flat Earth, and that his voyages refuted that belief, has been referred to as the myth of the flat Earth.[6] Historical development[edit] Ancient Near East[edit] The Jewish conception of a flat earth is found in biblical and post-biblical times.[7][8][9] In early Egyptian[10] and Mesopotamian thought the world was portrayed as a flat disk floating in the ocean.

New Journal of Physics Within the last two decades, quantum technologies (QT) have made tremendous progress, moving from Nobel Prize award-winning experiments on quantum physics (1997: Chu, Cohen-Tanoudji, Phillips; 2001: Cornell, Ketterle, Wieman; 2005: Hall, Hänsch-, Glauber; 2012: Haroche, Wineland) into a cross-disciplinary field of applied research. Technologies are being developed now that explicitly address individual quantum states and make use of the ‘strange’ quantum properties, such as superposition and entanglement.

Polarity Theory & Principles, Energy Healing, Esoteric Healing. Spiritual Healing Principles By virtue of these elements, the physical human body is created. The body is a composite of the interaction of the five elements (which are electromagnetic in nature) in the physical domain. The body, then, is an electromagnetic energy system expressing the dynamic interplay of the five elements from their most subtle to their most dense forms. Each form manifests a unique anatomy, with the most subtle form expressed as a "wireless" circuitry directing the flow of energy in its etheric state. Thus are created not only all aspects of the body, but also the totality of human expression, described by Dr. Stone as the Pentamirus combination of the elements.The student is also introduced to the idea that healing and disease are processes that can be described in energetic terms. Pierre Pannetier Dr Stone's successor teaching at Heartwood The body is seen as an intricate and dynamic interplay of the Three Principles and Five Elements which creates its subtle anatomy and physiology.

Religious cosmology Biblical cosmology[edit] The Bible was formed over many centuries, by many authors, and reflects shifting patterns of religious belief; consequently, its concepts of cosmology are not always consistent.[1][2] Nor should the Biblical texts be taken to represent the beliefs of all Jews or Christians at the time they were put into writing: the majority of those making up Hebrew Bible or Old Testament in particular represent the beliefs of only a small segment of the ancient Israelite community, the members of a late Judean religious tradition centered in Jerusalem and devoted to the exclusive worship of Yahweh.[3] Christianity/modern Judaism[edit] Around the time of Jesus or a little earlier, the Greek idea that God had actually created matter replaced the older idea that matter had always existed, but in a chaotic state. This concept, called creatio ex nihilo, is now the accepted orthodoxy of most denominations of Judaism and Christianity. Mormon cosmology[edit] Islamic cosmology[edit]

Pourquoi est-il si difficile de changer ? Parfois nous connaissons ce qui nous rend malheureux et ne faisons pas ce qui pourrait changer. Pourquoi reproduire sciemment les mêmes erreurs ? Comment en finir avec ce scénario répétitif ? Pourquoi ne changeons-nous pas, alors que nous sommes conscients des problèmes qui proviennent de la répétition des mêmes comportements ? À force d’écouter des histoires de vie dramatiques, j’ai été amené à m’intéresser à leurs trames et à mettre en relation ces récits avec les scénarios de films représentant des métaphores, ce qui facilite le dialogue en thérapie cognitive. Un scénario de vie est une situation piège dans laquelle un sujet se débat, sans succès, et qui se répète en de nombreuses occasions tout au long de la vie. Un rôle distribué une fois pour toutes Figée dans son personnage, la personne scénarisée va maintenir des relations stéréotypées et insatisfaisantes avec les autres.

A First Course in Linear Algebra (A Free Textbook) Open Content Mathematics Curriculum This is an evolving description of books and software that could be used to design a totally open undergraduate mathematics curriculum. This is meant to be a selective list, so you can consider these to be personal recommendations, not just links I've found promising. First some comprehensive software, then lower-division (including introductory programming), concluding with upper-division (alphabetically by subject). OpenLink Data Explorer Extension Laissez-faire learning Many of us are familiar with the term “laissez-faire economics.” What does “laissez-faire” mean? From the French, it literally means, “let do,” or by implication, let it be. In the fall of 2005, I officially began my homeschool career. I couldn’t help wondering if I was denying my son, and even myself, some momentous life mile marker, a rite of passage that every mother dreads, yet looks forward to. It started out easily enough, if a bit anti-climactic. So, what does it take to convince you that homeschooling works? My two children have never been to school. They often wonder how I make my children do their work. When I answer “no,” they look dubious. For three years, I dutifully researched and ordered curriculum which covered all of the subjects taught in most schools, whether public or private. I questioned whether or not I was “doing the right thing.” Laissez-Faire. I never suggested to him that he “learn” any of these things. Therefore I submit “laissez-faire learning.”
