10 Steps For Self-Hypnosis
April 28, 2008
Hypnosis is “a trance-like state that resembles sleep but is induced by a person whose suggestions are readily accepted by the subject.” The technique is used for medical purposes to relieve anxiety or otherwise improve or alter behavior. It is also used in popular stage acts in which subjects are persuaded to perform bizarre feats. Other variations include mass-hypnosis, in which crowds are simultaneously influenced, and auto suggestion in which a subject persuades them.
Steps For Self-Hypnosis
- Go to a comfortable, private place and sit in any comfortable chair or couch. Whether you sit or lie, ensure you do not cross your legs or any part of your body.
- Make sure you are not going to be disturbed for at least half an hour.
- Close your eyes and try to rid your mind of any feelings of fear, stress, or anxiety. When you begin, you will find it difficult not to think. You may find that thoughts keep intruding. When this happens, don’t try to force the thoughts out. Observe them impartially, and then let them slip away.
- Recognize the tension in your body. Beginning with your toes, imagine the tension slowly falling away from your body and vanishing. Imagine it freeing each body part one at a time starting with your toes and working its way up your body. Visualize each part of your body becoming lighter and lighter as the tension is removed. Relax your toes, then your feet. Continue with your calves, thighs, hips, stomach and so on, until you’ve relaxed each portion, including your face and head. Using imagery techniques of something you find comforting or soothing, such as water can be effective as well.
- Take slow, deep breaths. When you exhale, see the tension and negativity leaving in a dark cloud. As you inhale, see the air returning as a bright force filled with life and energy.
- Appreciate the fact that you are now extremely relaxed. Imagine you are at the top of a flight of 10 stairs. Tell yourself that you are going to descend the stairs, counting each step down, starting at 10. Picture each number in your mind. Imagine that each number you count is further down and one step closer to the bottom. After each number, you will feel yourself drifting further and further into deep relaxation. As you take each step, imagine the feel of the step under your feet. Keep counting and stepping down until you reaches the bottom. Once you reach the bottom imagine that you are happy and relaxed. Consider rolling your eyes gently back into your head.
- At this point, you should begin to address the issue you’re concerned about. Speak in the present tense. Your subconscious mind does not understand negatives in speech – avoid using statements with negative connotation.
- Repeat your statements to yourself as many times as you wish.
- When you are satisfied, say to yourself that you will now count upwards from 0 to 10, and when you reach the number 10, you will slowly rise back to normal consciousness and remain calm and relaxed. Proceed to count upwards, again picturing the numbers in detail.
- Once you have ascended, give yourself a few moments before opening your eyes, and take your time getting up.
Earth Day
April 24, 2008
Earth Day was established in 1970 at a time when social activism was at a high. U.S. senator Gaylord Nelson recognized a growing environmental concern that had barely been addressed by the legislature. In setting aside April 22 to recognize human impact on the environment, Nelson hoped first and foremost to raise the awareness of politicians.
Nelson certainly achieved his goal. More than 20 million Americans participated in this first Earth Day celebration, causing voter-hungry politicians to take notice. The overwhelming response helped generate a new political focus on the environment. As that focus has become increasingly global, more people than ever are celebrating Earth Day around the world.
Earth Day is one of two different observances, both held annually during spring in the northern hemisphere, and autumn in the southern hemisphere. These are intended to inspire awareness of and appreciation for the Earth’s environment. The United Nations celebrates an Earth Day each year on the March equinox, a tradition that was founded by peace activist John McConnell in 1969. A second Earth Day, which was founded by U.S. politician Gaylord Nelson as an environmental teach-in in the late 1960s, is celebrated in many countries each year on April 22.
Founded by the organizers of the first April 22 Earth Day in 1970, Earth Day Network promotes environmental citizenship and year round progressive action worldwide. Earth Day Network is a driving force steering environmental awareness around the world. Through Earth Day Network, activists connect change in local, national, and global policies. Earth Day Network’s international network reaches over 17,000 organizations in 174 countries, while the domestic program engages 5,000 groups and over 25,000 educators coordinating millions of community development and environmental protection activities throughout the year. Earth Day is the only event celebrated simultaneously around the globe by people of all backgrounds, faiths and nationalities. More than a half billion people participate in Earth Day Network campaigns every year.
Physiology of blushing
April 22, 2008
There is evidence that the blushing region is anatomically different in structure. The facial skin, for example, has more capillary loops per square millimeter and generally more vessels per unit volume than other skin areas. In addition, blood vessels of the cheek are wider in diameter, are nearer the surface, and visibility is less diminished by tissue fluid. These specific characteristics of the architecture of the facial vessels led.
Mellander and his colleagues reported evidence for special vasodilatations mechanisms. They studied buccal segments of the human facial veins in vitro. Unlike veins from other areas of the skin, facial veins responded with an active myogenic contraction to passive stretch and were therefore able to develop an intrinsic basal tone. Additionally Mellander showed that the veins in this specific area were also supplied with beta-adrenoceptors in addition to the common alpha-adrenoceptors. These beta-adrenoceptors could exert a dilator mechanism on the above-described basal tone of the facial cutaneous venous plexus. Mellander and his colleagues propose that this mechanism is involved in emotional blushing. Drummond has partially confirmed this effect by pharmacological blocking experiments. In a number of trials, he blocked both alpha-adrenergic receptors and beta-adrenergic receptors. Blushing was measured at the forehead using a dual channel laser Doppler flow meter. Subjects were undergraduate students divided into frequent and infrequent blushers according to self-report. Their mean age was 22.9 years, which is especially favorable for assessing blushing, since young subjects are more likely to blush and blush more intensively. The subjects underwent several procedures, one of which was designed to produce blushing. Alpha-adrenergic blockade with phentolamine had no influence on the amount of blushing in frequent or in infrequent blushers, indicating that release of sympathetic vasoconstrictor tone does not substantially influence blushing. This result was expected since vasoconstrictor tone in the facial area is known to be generally low. Beta-adrenergic blockade with propranolol on the other hand decreased blushing in both frequent and infrequent blushers. However, despite complete blockade, blood flow still increased substantially during the embarrassment and blushing inducing procedure. Additional vasodilator mechanisms must therefore be involved. So far, no specific mechanism has been suggested.
Photobucket
April 16, 2008
Photobucket is an image hosting, video hosting, slideshow creation and photo sharing website. It was founded in 2003 by Alex Welch and Darren Crystal and received funding from Trinity Ventures.
Photobucket was named the fastest growing site of 2005 according to Nielsen/Netratings and now ranks as a Top 50 site by traffic according to ComScore. As of Mid-December, 2007 Photobucket claims to have over 5,000,000,000 (5 billion) images uploaded to their site. Since new members are constantly joining, this result in more simultaneous uploads and thus the rate at which the numbers climb is constantly increasing. In March 2007 Photobucket had a market share of 41.4 percent of U.S. visits to photography web sites. As of March 28, 2007 Fortune Magazine reports that Photobucket has 36 million registered users and adds 85,000 new users per day. Fortune Magazine claims that more users visit Photobucket each month than Facebook. 56% of users are under 35, and 52% are female. According to TechCrunch, 300,000 unique websites link back to Photobucket. Photobucket’s investment bank, Lehman Brothers, values the company at $300 – $400 million or more
Features of Photobucket
Photobucket is usually used for personal photographic albums, remote storage of avatars displayed on Internet forums, and storage of videos. Photobucket’s image hosting is often used for eBay, MySpace (now a corporate cousin), Bebo, Neopets and Facebook accounts, LiveJournals or other blogs, and message boards. They advertise 99.9% uptime, and offer 1 GB free storage (5 GB with paid account), 100 GB free bandwidth (unlimited with paid account). Photobucket does not host sexually explicit content. Photobucket may drop content holders at their will for violating the TOS without giving any further details. Photobucket supports FTP, but the user must be a Pro account holder. Windows XP Publisher is supported as an alternative to FTP. It is available in free accounts.
Artificial Intelligence
April 11, 2008
Artificial intelligence (AI) is both the intelligence of machines and the branch of computer science that aims to create it.
Major AI textbooks define artificial intelligence as “the study and design of intelligent agents,” where an intelligent agent is a system that perceives its environment and takes actions, which maximize its chances of success. AI can be seen as a realization of an abstract intelligent agent (AIA), which exhibits the functional essence of intelligence. John McCarthy, who coined the term in 1956, defines it as “the science and engineering of making intelligent machines.”
Among the traits that researchers hope machines will exhibit are reasoning, knowledge, planning, learning, communication, perception and the ability to move and manipulate objects. General intelligence (or “strong AI”) has not yet been achieved and is a long-term goal of AI research.
AI research uses tools and insights from many fields, including computer science, psychology, philosophy, neuroscience, cognitive science, linguistics, ontology, operations research, economics, control theory, probability, optimization and logic. AI research also overlaps with tasks such as robotics, control systems, scheduling, data mining, logistics, speech recognition, facial recognition and many others. Other names for the field have been proposed, such as computational intelligence, synthetic intelligence, intelligent systems, or computational rationality
A headache
April 8, 2008
A headache is a condition of pain in the head; sometimes neck or upper back pain may also be interpreted as a headache. It ranks amongst the most common local pain complaints.
The vast majority of headaches are benign and self-limiting. Common causes are tension, migraine, eyestrain, dehydration, low blood sugar, and sinusitis. Rare are headaches due to life-threatening conditions such as meningitis, encephalitis, cerebral aneurysms, extremely high blood pressure, and brain tumors. When the headache occurs in conjunction with a head injury the cause is usually quite evident.
Treatment of an uncomplicated headache is usually symptomatic with over-the-counter painkillers such as aspirin, paracetamol, or ibuprofen, although some specific forms of headaches may demand other, more suitable treatment. It may be possible to relate the occurrence of a headache to other particular triggers, which can then be avoided.
Diagnosis for headaches
While, statistically, headaches are most likely to be harmless and self-limiting, some specific headache syndromes may demand specific treatment or may be warning signals of more serious disorders. Some headache subtypes are characterized by a specific pattern of symptoms, and no further testing may be necessary, while others may prompt further diagnostic tests.
Headache associated with specific symptoms may warrant urgent medical attention, particularly sudden, severe headache or sudden headache associated with a stiff neck; headaches associated with fever, convulsions or accompanied by confusion or loss of consciousness; headaches following a blow to the head, or associated with pain in the eye or ear; persistent headache in a person with no previous history of headaches; and recurring headache in children.
The most important step in diagnosing a headache is for the physician to take a careful history and to examine the patient. In the majority of cases the diagnosis will be a “primary headache” which means that the headache, whilst unpleasant is not an occurring as a manifestation of a more serious condition. The main types of primary headache are tension headache, migraine and the trigeminal autonomic cephalalgias of which cluster headache is an example. As it is often difficult for patients to recall the precise details regarding each headache, it is often useful for the sufferer to fill-out a “headache diary” detailing the characteristics of the headache. When the headache does not clearly fit into one of the recognized primary headache syndromes or when atypical symptoms or signs are present then further investigations are justified. Computed tomography scans of the brain or sinuses are commonly performed, or magnetic resonance imaging in specific settings. Blood tests may help narrow down the differential diagnosis, but are rarely confirmatory of specific headache forms.
