Business intelligence (BI) is an umbrella term that refers to a variety of software applications that analyze a company’s data and extract useful insights to help managers make better strategic decisions. Business intelligence includes activities such as data mining, which searches out and analyzes data from multiple sources across the enterprise, and sometimes from outside sources, to identify patterns and relationships that might be significant, as well as online statistical analysis, querying, and reporting. Many managers like getting BI information via a business performance dashboard because it provides a user-friendly way to view and navigate through information.

“My dear knights whom I love, always remember this: whether you seek for a vision, or do humble service as monks, or fight to right wrongs. Whatever you do, your aim must be to make yourself useful to the world by the work for which you are best fitted.”

~By King Arthur

I have been reading the books, “King Arthur and His Knights” in these days and I am very much moved by the above quote. That is really impressive.

Einstein assumed that physical laws remain the same for both the moving observer and the stationary one, including observer and the stationary one, including that the speed of light is the same for both. These simple assumptions have great consequences, called the special theory of relativity. Time merges with space, objects shrink in the direction of motion, the speed of light in a vacuum cannot be exceeded, and mass can be converted into energy or energy into mass.

By 1915, Einstein had worked out the consequences for one observer accelerating with respect to the other. He assumed that gravity is the same as the force that keeps a body moving in a straight line (ignoring friction or other forces). This leads to the general theory of relativity, which implies that gravity results from mass causing space to curve.

In the movie, Adrian Helmsley (Chiwetel Ejiofor), the American Geogolist say the White House Chief of Staff Carl Anheuser (Oliver Platt):  “People have RIGHT to know that.” And yes, I am strongly agree on that. We have right to know what is happening around us. The Earth is our home, it is where we are born and a place we will rest in peace. So, we should at least know what is happening to our home.

Exactly the same as in the Christian Legend, goverment has built the very big ship which can carry selected people, animals and some treasures so that we can continue our human race during the dark period and bring all the stories of the past to the youngsters. But I oppose with that idea. It works very well because it is movie. As in reality, they are more like dreaming. When the world really comes to its end, it takes million of years to transform itself to become a place which is suitable for living things to live. So, our youngsters are not going to survive till this period and even if they can, who knows how they are going to start the world again ? It is a mystery.

Sigmund Freud argued that we repress early memories , presumably because they are painful . Although we do not have access to them , he maintained , they are still present in the brain and can thus affect our psychological well-being . Cognitive psychologists , in contrast , argue that early memories are simply not stored in any format that we can access . This may be primarily because we lack language during infancy , so memories must be recorded nonverbally . Finally , neuroscientists note that the hippocampus , an area of brain involved in forming memories , matures fairly early in life . Thus , they believe early memories must be shipped off to the neocortex-an area involved in higher-level cognitive processes-for long-term storage . Because the neocortex is relatively immature until the toddler or preschool period , it stands to reason that young children would have relatively poor long-term memories . All of these explanations apply only to facts and events that can be consciously recalled . Little is known about memories acquired unconsciously , such as learning how to toss a ball . These memories seem to remain intact later in life , although how they are retrieved is a mystery.

Because humans have such a poor understanding of randomness , it is very difficult for us to produce randomness on our own . Try this yourself . On a computer keyboard , type a long string of random characters . As you type , you will notice that it is difficult producing data that would be considered truly random . Chances are you will have many asdf and uiop sequences in your typing .

To make matters worse , the harder you try to be random , the more predictable you become (e.g.,you might purposely avoid any redundancy or obvious patterns and as a rusult create other predictable patterns ) . Consider the ” guess-which-hand ” game . Put an object in one of your hands , place both hands behind your back , and ask a child to guess which hand the object is in . At that point , their guess will be somewhat random . Play it again and this time their guess is largely based on the result of the last game (e.g., if they correctly guessed the left hand last time , they might try guessing the left hand again next time ) . On the other hand , they might be smarter and expect you to switch so they guess the right hand . Play the game repeatedly and you will see patterns develop in both your selection and the child’s response .

If you give someone a handful of pennies and ask them to spread the pennies out randomly on a table , you will find that at first glance , most people seem capable of arranging the pennies in a manner that looks random . But , often if you look closely , there is some pattern that defines the randomness ( e.g., although the pennis look randomly arranged , the space between each panny might actually be the same ) . In our attempt to create randomness , we will fall back to some pattern .

Our lack of randomness is evident in our passwords . We tend to use words close to our personal lives or our environment . We pick numbers and words that mean something to us rather than selecting from the entire range of avaliable words . We might try to open a dictionary to a random page and pick a word , but even where we open the book or what part of the page we select from has bias .

Anger can have a detrimental effect on physical and emotional health . It is often a signal that something needs to be dealt with and if left unchecked , anger can lead to violence . Therapists sometimes teach their clients to express their anger in a physical way by hitting cushions or screaming out . Sometimes , however , this can have the effect of strengthening the angry feelings , so it is far better to change your irrational beliefs and then try and resolve the matter in a practical way .

The lack of order , however , does not guarantee that something is random . A sequence is noly random if there is no way it can be reproduced given any circumstances or information ( e.g., the value of Pi appears random but there is a specific method used to reproduce those digits ).

It is difficult to actually determine if a sequence is truly random ; therefore we look at several properties of a sequence to determine its randomness :

1. Even Distribution An equal probability of distribution over the entire set of data .
2. Unpredictability Any one piece of data has no relationship to any previous data and provides no information about the data to follow.
3. Uniqueness It would be extremely rare to randomly produce the same sequence of data more than once . The longer the sequence , the more unique it becomes .

These three properties deem random data impossible to guess , therefore making randomness a vital element for strong passwords .

Unfortunately , completely random passwords are very difficult to remember and even if we could remember them , creating them would be a complicated task .

Work stress

 It has been suggested that work is the biggest cause of stress in the western world today . The pace of change in the way we work has never been as great . People have to cope with new information technology , longer working hours and short-term contracts . A job is no longer for life . As job insecurity increases , people are more likely to remain in a job that is perhaps safe but not necessarily suited to them .

Family and relationship stress

People experience high levels of stress in their relationships . From marital conflict and difficult children to alcoholism and violence the problem are wide and varied . These issues need to be properly addressed otherwise the consequences can be serious , leading to separation , divorce and family breakdown .

The stress of bereavement

The loss of a loved one is a devastating life experience . When we lose someone close , it is natural to go through a process of mourning . The emotions and stages of the grieving process will vary from person to person . First there is the initial shock of the loss and at this time it is common to experience a feeling of numbness . Anger , guilt , and despair follow as the reality of the loss deepens . This is followed by recovery as the person accepts the bereavement and begins to rebuild their life . It is important to acknowledge the grief and talk to someone close .

The stress of Financial problems

Financial problems obviously cause an enormous amount of stress . The loss of a job , an addition to gambling or mounting bills can lead to family tensions . Ignoring the problem will only make matters worse . When faced with money worries , it is important not to panic . Instead talk to your debtors and set realistic budget .

The stress of Change

Changes in our life , however big or small , whether positive or negative , can create stress . Major life changes such as starting a new job , getting married or moving house can challenge our abilities to cope . This is particularly true if we experience too many changes in a short period of time . Although change is an inevitable part of life , it makes sense to plan ahead . Whenever possible do not take on too much at once .

Environmental stress

Our environment is a big factor in the cause of stress . We have to contend with crowded trains , noisy traffic and polluted cities . These conditions can lead to health-related problems such as asthma , allergies and migraine headaches . We cannot easily escape the environment we live in . However , healthy eating , exercise and regular breaks can help us to better cope with the stresses and strains of city life .

When a person believes demands made of them exceed their ability to cope they will experience stress .

The technical name for these demands is ” stressors ” and the resulting wear and tear on the body is the stress .

We may think of stress as a relatively new phenomenon ; in fact , it has been with us for millions of years . Many years ago when men and women lived in caves life-threatening situation occured on a daily basis . Cave dwellers hunting for food were regularly exposed to physical dangers from other predators or the environment in which they lived .

Faced with a threat the body reacts immediately – there is a rush of adrenaline , heightened muscle tension , faster heart rate and raised blood pressure . Blood pumps to the muscles and brain causing the body to become alert and as strong as possible for , in order to survive , a hunter would have to respond either by fighting the threat or running away from it . This is called the ” flight and fight response ” and is activated whenever a person is faced with an emergency . Physiologist Walter B Cannon first described it over 100 years ago .

The flight or fight response is still experienced by people today and is , of course , appropriate whenever we are faced with a real emergency . However , unlike our ancestors , we are rarely faced with such life-threatening situations . Screaming children , nagging bosses and work deadlines are very unpleasant but hardly life-threatening . The problem is that nature does not know this and will prepare the same fight or flight response . This leave the body in a high state of arousal which it is a unable to utilise .

So if everyday pressures mount up and a person is in this state for long periods of time , their body soon suffers and the experience becomes distress .
