Numerology

...oldwitchcraft.com 3 INTRODUCTION The science of numerology can be traced back thousands of years. The Chinese, Japanese, Greek, Hebrews, Egyptians, Phoenicians, early Christians, Mayans, and Incas all used some form of numerology to gain a deeper understanding of themselves and the universe. Numerology is perhaps the easiest of the occult arts to understand and use. All you need is the birth date and the complete name of an individual to unlock all of the secrets that the numbers hold. (Most authorities agree that the full birth name as recorded on your birth certificate is the name that must be used for all calculations involving name.) There are eleven numbers used in constructing Numerology charts. These numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, and 22. Larger numbers that occur from adding the numbers in the complete birth date or from the values assigned to each name are reduced by adding the digits together until the sum achieved is one of the core numbers. Merely add the components of the larger number together (repeatedly, if necessary) until a single digit (or the "master" numbers 11 or 22) results. Each of these numbers represents different characteristics and expressions. Master numbers are the only exception to rule of reducing to the single digit. The master numbers 11 and 22 are intensified versions of the single digit number they replace (2 and 4). These numbers suggest a potential for a high degree of learning and/or achievement very often in a more stressful environment...

...to the majority, it is never without costs for the minority. Concerns over sovereignty often slow or stop integration attempts. The creation of single markets in the EU and North America means that many markets that were formerly protected from foreign competition are now more open. This creates major investment and export opportunities for firms within and outside these regions. The free movement of goods across borders, the harmonization of product standards, and the simplification of tax regimes make it possible for firms based in a free trade area to realize potentially enormous cost economies by centralizing production in those locations within the area where the mix of factor costs and skills is optimal.

Review of Fellini's 81/2

...8½ Produced by Angelo Rizzoli. Directed by Federico Fellini. Screenplay by Federico Fellini, Tullio Pinelli, Ennio Flaiano, Brunello Rondi. Viewers expecting to sit back, relax and switch off for a couple of hours - this film is not for you. A barrage of dream sequences interrupted by brief encounters with endless characters; this is a piece of shamelessly self indulgent psychoanalysis on Fellini's part. Of course, this is exactly what he intended. The main character is that of Guido (played by Fellini himself) a director unable to complete his latest film and loosely based on the identity of his own creator (Fellini). Fellini has been able to achieve the effect of mise en abyme not only through the dream sequences but also with this being an autobiographical piece. Viewers are intentionally lulled into the false belief that they are watching a film about Fellini, not the character Guido. Throughout, obvious references to the films chaos and irregularities are made by characters through their criticism of the unfinished, fictional film. When giving Guido notes on his film, one character calls it 'a chain of gratuitous episodes' which pretty much describes Fellini's 8½ to perfection. In another scene Guido is criticised for his obsession with depicting 'Italy's Catholic conscience' which is also a reoccurring motif of Fellini's. He plays this game with the viewer by highlighting the inadequacies of his own film through the criticism of the fictional one. An endless array...

Chapter 8 Unit Guides

...8.3 While other countries have more formal parties, America’s political parties are decentralized, with city, state, and national bodies. State governments are responsible for holding elections, and each state has its own special party organization. Although government in the states level is becoming more formal, a majority of presidential campaigning is done through the candidate’s personal campaign organization. Each state has a different way to carry out elections. One factor they decide on is which type of primary to have: closed, open, or blanket. Until the 1930’s, party machines, which were commonly corrupt, had a huge influence over city governments. By using the patronage system, they kept members loyal by giving them important positions in government. While local parties have declined today, county-level parties have had more activity in their elections. Each party has its own national committee. The national committee is in charge of writing the party platform and nominating a presidential and vice presidential candidate to represent the party at the national convention. During nonelection years, the national committee is in charge of maintaining the party organization. 8.4 During the elections, parties attract voters with their accomplishments and promises. Those who are attracted to these party’s platforms form coalitions in support of certain policies. Presidents don’t rely as much on coalitions as they used to because television has allowed them easier access...

...History of National Women's History Month The Beginning As recently as the 1970's, women's history was virtually an unknown topic in the K-12 curriculum or in general public consciousness. To address this situation, the Education Task Force of the Sonoma County (California) Commission on the Status of Women initiated a "Women's History Week" celebration for 1978. We chose the week of March 8 to make International Women's Day the focal point of the observance. The activities that were held met with enthusiastic response, and within a few years dozens of schools planned special programs for Women's History Week, over one-hundred community women participated in the Community Resource Women Project, an annual "Real Woman" Essay Contest drew hundreds of entries, and we were staging a marvelous annual parade and program in downtown Santa Rosa, California. Local Celebrations In 1979, a member of our groups was invited to participate in Women's History Institutes at Sarah Lawrence College, attended by the national leaders of organizations for women and girls. When they learned about our county-wide Women's History Week celebration, they decided to initiate similar celebrations within their own organizations and school districts. They also agreed to support our efforts to secure a Congressional Resolution declaring a "National Women's History Week." Together we succeeded! In 1981, Sen. Orrin Hatch (R-UT) and Rep. Barbara Mikulski (D-MD) co-sponsored the first Joint Congressional...

8 Seconds Critique

...8 Seconds Justin Richard ENG225 Instructor Schmidt December 19, 2011 8 Seconds There are thousands of movies that can be broken down and analyzed but there are a handful of films that tell a story about a cowboy doing what he loves most. In the 1994 film entitled, 8 Seconds, one should stop and analyze all the elements from the story that was told to the overall textual themes that showed why this film was truly a heartwarming experience through the life of Lane Frost. All directors have a story to tell through a film being created. He or she will use either a chronological order or a non-linear order to help guide the audience through the story. Goodykoontz & Jacobs (2011) states, “Most movies follow a standard chronological order, which means that events in the movie’s plot follow the same order they would occur in the story, the order of real time” (p 2.3). John Avildsen, the director of 8 Seconds, used a chronological order to escort the audience through Lane’s life from the time he was a young child riding sheep at the fair to a world champion bull rider. The story starts in 1968 as a kid trying to hold on for dare life in a sheep riding contest at the local fair somewhere in Oklahoma. Immediately following this scene, the director takes us to Lane riding bulls in the All Teen Rodeo Championships; which Frost wins first place after riding a bull for eight seconds. After the early years of learning the techniques of riding bulls from his father he...
