Staying Calm and Cultivating Poise

Marcus Aurelius practiced psychotherapy in the more pretentious and stilted style appropriate, perhaps, to his time and position. From this philosopher-emperor each of us will do well to absorb the following quotation: "Begin the morning by saying to yourself, I shall meet with the busybody, the ungrateful, arrogant, deceitful, envious, unsocial. All these things happen to them by reason of their ignorance of what is good and evil."

Why shouldn't we be prepared beforehand to view all these people with pity instead of resentment? Their attitude toward us and their abuse of us has really nothing to do with us, but means merely an exploitation of their peculiarities. To prepare ourselves in this way to meet ridicule, abuse, and the like means no more than for a sailor to be ready to put down the helm in a squall. If we should set about learning to sail a boat, this is one of the first things we should do, but we pay very little attention to learning how to run ourselves. On this point Epictetus says, "Cease to make yourselves slaves. Is there not some advantage to be gained from this man? From all: even a reviler. Does not the wrestler gain advantage from him with whom he exercises before the combat? The greatest. And just in the same manner I can exercise myself with this man - and the heavier he is the better for me; and it is surely an advantage to me when I am exercised in gentleness of temper. This is knowing how to gain an advantage from men."

The brief maxim should be constantly at command to clench such suggestions. Try keeping these in mind as you go about your daily live. "These are the annoyances incident to my business. To fret when they occur means that I cannot manage my business without friction." Another is this (for use when subordinates show stupidity), "If he had my brains he'd have my job". And finally (as a shield against everyday annoyances and resentments), "Never touched me."

I can think of no better illustration of the way such maxims should be ready for immediate use than the following instance, in which the laugh, by the way, was on me. I was walking with a friend one day when an automobile came up behind us, announcing its approach by one of those peculiar notes so far from the honk of a self-respecting goose that it can be described neither as a groan, grunt, growl, nor scream, but rather as possessing the discordant elements of all four. " Don't you hate those freak horns!" I exclaimed, rather petulantly. "I used to," he said, "but since reading your book I say to myself, 'Never touched me!'"

This incident marks the progress respectively of my friend and myself in mental training. For I have no hesitation in presenting myself, not as a past-master, but rather as a student-instructor in this branch of practical philosophy.

One of the principal depressing emotions we have to curb to preserve our poise are anger. And under anger we must include the moderate degree of anger known as fret. What makes us fret? We all know the expression "Mad as a wet hen". Suppose you were asked what makes the hen mad, you probably would answer, "Why, because she is wet"; but for the real reason we must go further back - she is mad because she insists on being dry. If she could forego that insistence she would remain unruffled, wet as well as dry.

Similarly, I think I am mad because so-and-so has called me a liar, a coward, or a what-not. But the underlying cause of my anger is that I can't stand being called such names. If I took a notion to practice philosophy to the extent of seeing how much instead of how little I could stand, I might finally be wishing some one would try it on, to see if I couldn't remain cool under the provocation, and simply say to myself, "Never touched me." "Any one can stand what he likes; it takes the philosopher to stand what he doesn't like."

There is no sharp line of division between the legitimate airing of a grievance and going into a state of fret. Nor is it fretting quietly to go about the adjustment of the grievance. Fret means internal turmoil externalized, not by effective work, but by wailing and gnashing of teeth.

You can spot a fretter from the tone and pitch of his voice. This test is not infallible but as a rule you can spot a fretter by his voice. When someone frets, his vocal cords tighten and produces a high-pitched, disagreeable tone which merges into the whine of chronic discontent.

I heard such a high-pitched voice inquiring the waiter one morning at breakfast, "How many eggs are there in this bacon and eggs?" "I don't know, sir, I think two... that is the usual number." "Well, I wish you would go and see"; and the waiter did so, returning shortly to announce with beaming face, "There are three, sir; they generally put in two, but this time they put in three." But even this cheerful news produced no change in the expression or the voice of the fretter, who despondently observed, "I knew the proportions were wrong." If you ever find yourself getting into this state of mind try the experiment of saying to yourself, " Don't pitch your voice so high!"

I once knew a man who was so obsessed with dust. If you inquired about his health, he would answer, " Pretty bad, thank you, and the dust is something awful!" If you admired a picture, he would say, "The composition may be good, but the frame is the kind that catches the dust." If you mentioned the Arctic regions, he would wish himself there to be out of the dust. When we finally had a fall of snow that covered the dust, I expected to find him beaming, but no - with the same tried expression and the same high-pitched voice he said the dust would be as bad as ever in a little while.

It is surprising how many things we can't stand if we cultivate our "can’t-standability." The degree of anger known as getting mad may be dismissed with an appeal to our vanity, thus: Consider the very angry woman. How unbecoming it is - how it lacks in dignity! Why, she is almost black in the face because her emotion interferes with her circulation, and causes a stasis of venous blood in the superficial vessels of her countenance! If she could look in the glass now, and if she knew enough physiology to realize that controlling the emotions also controls the circulation, she would wish never to be angry again.

It is worth while for us to profit by this observation; and if it chances that we are the object of her wrath, we shall do well to curb the natural reflex which will make our face as black as hers, and we shall maintain the role of spectator, disinterested and unaffected.

When real improvement has taken place in these directions there is not only a change in the manner of thinking, but a noticeable change of personality, which includes control of the body likewise. Indeed, to control the body or mind alone is to manage only one horse of a team.

3 laws of memory or of thinking that you must know

There are 3 laws of memory or of thinking that you must know if you are serious about developing a sharp memory.

The first and principal thing the pupil requires to do in this lesson after learning the definition of thefollowing Three Laws - is to be able to clearly understand the examples under each Law, and whether they verify or illustrate that Law.

LAW I
INCLUSION indicates that there is an overlapping of meaning between two words, or that there is a prominent idea or sound that belongs to both alike, or that a similar fact or property belongs to two events or things as, to enumerate a few classes:- Whole and Part -

(Earth, Poles) (Ship, Rudder) (Forest, Trees)
(Air, Oxygen) (House, Parlor) (Clock, Pendulum)
(Knife, Blade) (India, Punjab) (14, 7) (24, 12)
Genus and Species. - (Animal, Man) (Plant, Thyme)
(Fish, Salmon) (Tree, Oak) (Game, Pheasant)
(Dog, Retriever) (Universal Evolution, Natural Selection)
(Silver Lining, Relief of Lucknow)
(Empress Queen, Victoria) (Money, Cash)

Abstract and Concrete. [The same Quality appears both in the Adjective and in the Substantive.] -
(Dough, Soft.) (Empty, Drum.) (Lion, Strong.)
(Eagle, Swift.) (Courage, Hero.) (Glass, Smoothness.)
(Gold, Ductility.) (Sunshine, Light.) (Fire, Warmth.)

Similarity of Sound.
(Emperor, Empty.) (Salvation, Salamander.)
(Hallelujah, Hallucination.) (Cat, Catastrophe.)
(Top, Topsy.)
[Inclusion by sound is not punning.]

Simple Inclusion embraces cases not found in either of the foregoing classes, but where there is something in common between the pairs, as
(Church, Temple.) (Pocket, Black Hole.)

LAW II
EXCLUSION means Antithesis. One word excludes the other, or both words relate to one and the same thing, but occupy opposite positions in regard to it, as

(Riches, Poverty.) (Hot, Cold.) (Old, Young.)
(Damp, Dry.) (Life, Death.) (Love, Hate.) (Joy, Sorrow.)
(Courage, Cowardice.) (Health, Sickness.)
(Righteous, Wicked.) (Beauty, Ugliness.) (Peace, War.)

LAW III
CONCURRENCE is the sequence or co-existence of impressions or ideas that have been either accidentally or causally together. It is either the accidental conjunction of experiences or the operation of cause and effect; since even in the latter case, it is merely the sensuous facts of immediate succession that we know about, as

(Gravitation, Newton, Apple.)
(Dives, Lazarus, Abraham, Bosom.) (Pipe, Tobacco.)
(Michaelmas, Goose.) (Columbus, America.)
(Bartholomew Diaz, Cape of Good Hope.)
(Grandmother, Knitting) (Socrates, Hemlock.)
(Bruce, Spider.) (Nelson, Trafalgar.)
(Demosthenes, Seashore, Stammering, Pebbles.)
(Job, Patience.) (Wedding, Slippers, Cake.)
(Wellington, Bonaparte, Waterloo.)
(Depression, Fall of Silver.) (Lightning, Thunder.)

In the case of the following pairs, one word has been so often appropriated to the other, that there seems to be something in common in the meaning of the terms - but it is not so, they are mere cases of Concurrence, but of almost indissoluble Concurrence.

For instance, a man might examine a "spade" in all its parts and might even make one after a model, and not even know what "dig" means. The mention of "dig" is as likely to make us think of pickaxe as of spade. "Spade" does not mean "dig" nor does "dig" mean spade. "Dig" merely means the action of the "spade," or the use to which it is put. Hence this pair of words does not furnish an example of Inclusion. But as "dig" is frequently appropriated to "spade" - as we have often thought of those words together - this is a case of strong Concurrence. The term "swoop" is almost exclusively applied to "eagle."

A certain action or movement of the eagle is termed swooping. But "eagle" does not mean "swoop," nor does "swoop" mean "eagle." We always think of "eagle" when we think of "swoop," but we do not often think of "swoop" when we think of "eagle." It is not In, but Con.

Visitor Identification Methods Through Urchin

If I save an interesting-page, I see a file named "urchin" in javascript format. But I did'nt find it if I sae mine. So, I try to find more about this item in google search engine. Finally, I found a site explained about it.

I will re-write here about the explanation so that I keep it in my this dear-blog directory.

The site explanation is folowing :

Overview

Urchin has five different methods for identifying visitors and sessions, depending on available information. Of these, the patent-pending Urchin Traffic Monitor (UTM) is a highly accurate system that was specifically designed to identify unique visitors, sessions, exact paths, and return frequency behavior. There are a number of visitor loyalty and client reports that are only available when using the UTM System. The UTM System is easy to install and is highly recommended for all businesses.

In addition to the UTM System, Urchin can use IP addresses, User-Agents, Usernames, and Session-IDs to identify sessions. The following table compares the abilities of each of the five identification techniques:

AbilityIP OnlyIP+User-AgentUsername Session ID UTM
Identifies non-proxied sessions XXX XX

XX
Defeats most provider caching


XX
Defeats browser caching



X

X
X

X

X

Data Model

The underlying model within Urchin for handling unique visitors is based on a hierarchical notion of a unique set of visitors interacting with the website through one or more sessions. Each session can contain one or more hits and pageviews. Pageviews are kept in order so that a path through the website for each session is understood. As shown in the diagram, the Visitor represents an individual's interaction with the website over time. Each unique visitor will have one or more sessions, and within each session is zero or more pageviews that comprise the path the visitor took for that session.

Proxying and Caching

In attempting to identify and track unique visitors and sessions, we are basically going against the nature of the web, which is anonymous interaction. Particularly troublesome to tracking visitors are the increasingly common proxying and caching techniques used by service providers and the browsers, themselves. Proxying hides the actual IP address of the visitor and can use one IP address to represent more than one web user. A user's IP address can change between sessions and in some cases multiple IP addresses will be used to represent a cluster of users. Thus, it is possible that one visitor will have different IP addresses for each hit and/or different IP addresses between sessions.

Caching of pages can occur at several locations. Large providers look to decrease the load on their network by caching or remembering commonly viewed pages and images. For example, if thousands of users from a particular provider are viewing the CNN website, the provider may benefit from caching the static pages and images of the website and delivering those pieces to the users from within the provider's network. This has the effect of pages being delivered without the knowledge of the actual website.

Browser caching adds to the question. Most browsers are configured to only check content once per session. If a visitor lands on the home page of a particular website, clicks to a subpage, and then uses the back-button to go back to the home page, the second request of the home page is most likely never sent to the website server, but pulled from the browser's memory. An analysis of paths may result in an incomplete path missing the cached pages.

In the above diagram, the actual path taken through the website by the client is shown at the top, while the apparent path from the server's point of view is shown at the bottom. In this case, before proceeding to Page-3 the user goes back to the Page-1. The server never sees this request and from its point of view it appears the user went directly from Page-2 to Page-3. There may not even be a link from Page-2 to Page-3.

Visitor Identification Methods

As mentioned previously, Urchin has five different methods for identifying visitors, sessions and paths. The more sophisticated methods which can address the above issues may require special configuration of your website. The following descriptions describe the workings of each method in more detail.

1. IP-Only: The IP-Only method is provided for backward compatibility with Urchin 3, and for basic IT reporting where uniquely identifying sessions is not needed. This method uses only the IP Address to identify visitor sessions. Thirty minutes of inactivity will constitute a new session. The only data requirements for using this method is a timestamp and IP Address of the visitor.

2. IP-Agent: The default method, which requires no additional configuration, uses the IP address and user-agent (browser) information to determine unique sessions. A configurable thirty-minute timeout is used to identify the beginning of a new session for a visitor. While this method is still susceptible to proxying and caching, the addition of the user-agent information can help detect multiple users from one IP address. In addition, this method includes a special AOL filter, which attempts to reduce the impact of their round-robin proxying techniques. This method does not require any additional configuration.

3. Usernames: This method is provided for secure sites that require logins such as Intranets and Extranets. Websites that are only partially protected should not use this method. The Username identification is taken directly from the username field in the log file. This information is generally logged if the website is configured to require authentication. This method uses a thirty-minute period of inactivity to separate sessions from the same username.

4. Session ID: The fourth visitor identification method available in Urchin is the Session ID method, which can use pre- existing unique session identifiers to uniquely identify each session. Many content delivery applications and web servers will provide session ids to manage user interaction with the webserver. These session ids are typically located in the URI query or stored in a Cookie. As long as this information is available in the log data, Urchin can be configured to take advantage of these identifiers. Using session ids provides a much more accurate measurement of unique sessions, but still does not identify returning unique visitors. This method is also susceptible to some forms of caching including the above example.

In many cases, the ability to use session ids may already be available, and thus, the time required to configure this feature may be short. For dynamically generated sites, taking advantage of this feature should be straightforward. The result is more accurate visitor session and path analysis.

5. Urchin Traffic Monitor (UTM): The last method for visitor identification available in Urchin is the Urchin Tracking Module. This system was specifically designed to negate the effects of caching and proxying and allow the server to see every unique click from every visitor without significantly increasing the load on the server. The UTM system tracks return visitor behavior, loyalty and frequency of use. The client-side data collection also provides information on browser capabilities.

The UTM is installed by including a small amount of JavaScript code in each of your webpages. This can be done manually or automatically via server side includes and other template systems. Complete details on installing UTM are covered in the articles later in this section.

Once installed, the Urchin Traffic Monitor is triggered each time someone views a page from the website. The UTM Sensor uniquely identifies each visitor and sends one extra hit for each pageview. This additional hit is very lightweight and most systems will not see any additional load. The Urchin engine identifies these extra hits in the normal log file and uses this additional data to create an exact picture of every step taken by the users. This method also identifies visitors and sessions uniquely so that return visitation behavior can be properly analyzed. While this method takes a little extra time to configure, it highly recommended for comprehensive detailed analytics.


Genetic Signpost from Genographic Project

This is explain about genome in our body which is generated from our parents. The explanation is in swf format (credit : nationalgeographic)







Are you an expert in genetic? I am interesting in this field since in my junior high school. It is so wonderfull to know how is our body create by the "generated-code". How about "clonning"?. That is another higher of human achieving in science and technology. (yeah, I thought)...any opinion from you?

Oil spills into Kan. river as flooding continues

OSAWATOMIE, Kan. - An oil spill added to the misery caused by widespread flooding Monday as thousands of evacuees in Kansas, Oklahoma and Texas waited for water to recede from their homes.

Kansas got a break from the weather Monday, but more rain was scattered over Texas and eastern Oklahoma, the latest in nearly two weeks of storms. It was the 20th straight day that rain had fallen in Oklahoma City.

“It’s such a dynamic situation,” said Parker County, Texas, spokesman Joel Kertok. “We get a break, and then it starts raining again.” LINK

Kansas officials said Monday they were trying to contain damage from the Coffeyville Resources oil refinery spill in the Verdigris River in Coffeyville, Kan., that occurred over the weekend as raging floodwaters wreaked havoc through the southeast part of the state.

Sea Urchin Genome Reveals Striking Similarities to Humans

Scientists already knew that the creatures, which resemble underwater hedgehogs, are one of only a few invertebrates (animals without backbones) on the human branch of the evolutionary tree.

Purple sea urchins feast on the remains of
a giant kelp in Carmel Bay, California.


Scientists have completed sequencing the genome of
the California purple urchin—revealing surprising
new information about just how
closely urchins resemble humans and
how vital a role the marine creatures play
in ocean ecosystems.

But a new sequence of the California purple urchin's genome reveals that the marine creatures and humans bear a striking number of similarities. (See related photo: "Sea Urchin Genome Decoded".)

"Comparing all the genes of the sea urchin, it's actually quite similar to us," said George Weinstock, who led the sequencing project. Weinstock is co-director of the Human Genome Sequencing Center at Baylor College of Medicine in Houston, Texas.

The sea urchin is one of the few marine organisms whose genome has been sequenced. The study therefore also provides insights into the vital role of sea urchins in many marine ecosystems.

"Sea urchins are major grazers in shallow seas of many parts of the world's oceans ... and they are the main prey of many top predators," said John Pearse, a biologist at the University of California, Santa Cruz.

Results from the sequencing project and accompanying articles, including one by Pearse, will appear in tomorrow's issue of the journal Science.

Kelp Forests

Sea urchins, which feed mainly on algae, live in environments that alternate between species-rich kelp forests and sea urchin-dominated "barrens."

"They are known to limit sea grass and kelp production and consequently the diversity and complexity in communities supported by these producers," Pearse said.

He compares sea urchins to rabbits and other grazers found on land.

"Sea urchins are the main prey of many top predators—including crabs, lobsters, fish, and sea otters—that directly limit their abundance, comparable to how coyotes, hawks, and owls limit the abundance of rabbits," Pearse said.

With a diminishing population of sea otters in California's Monterey Bay, for example, the population of sea urchins has multiplied. The sea urchins are reportedly chewing up the kelp forest in the area and upsetting the ecosystem. (Related video: "Killer Whale Mystery at Monterey Bay".) There are other factors that influence sea urchins' ecological role, including interactions among different urchin species.

"Populations of some species tend to explode and devastate the communities they are in, while others rarely do so," Pearse said. "Knowledge of their genome might allow people to better understand the underlying mechanisms that lead to such differences."

Sea urchins can also be used by scientists to detect toxic chemicals.

"One of the things in the genome project has been to come up with a very detailed description of the defense mechanism that sea urchins have to deal with toxic chemicals," Weinstock, of Baylor College of Medicine, said.

"Understanding their sensitivities and resistances could potentially help fine-tune our use of them, in terms of understanding the marine environment."

Humans are also directly affecting sea urchin populations. Sea urchin roe, or ovaries, are a delicacy in Korea and Japan.

The U.S. sea urchin fishery has been in decline in recent years, however, because of reduced demand from Japanese consumers. (Related: "Seafood May Be Gone by 2048, Study Says"

[November 2, 2006].)

Human Cousin?

The urchin's usefulness as a model for developmental biology was another major reason for the sequencing project.

Scientists have long used sea urchins to study fertilization and early development in humans.

"The series of steps that happen after an egg is fertilized by a sperm ... those very early events turn out to be the same in the sea urchin as they are in the human," Weinstock said.

The scientists identified more than 23,000 genes in the 814 million base pairs, or "letters," of DNA code taken from the sea urchin.

The sea urchin represents the first sequenced genome from the echinoderms, which are the closest known relatives of the chordates, the group that includes vertebrates, animals with spinal columns.

The genome includes analogs to many essential human genes that were previously thought to be exclusive to vertebrates.

But missing among the sea urchin genes are some genes found in flies and worms. This, scientists say, shows that sea urchins are closer kin to humans than beetles, flies, crabs, and clams.

"Humans and sea urchins have a common ancestor," Weinstock said.

The eyeless sea urchin also has genes associated with taste, smell, hearing, balance—and surprisingly, even vision.
