What are the best energy sources? "Best" depends on many factors - how the energy is being used, where it is being used, what energy sources are available, which sources are most convenient and reliable, which5 are easiest to use, what each costs, and the effects on public safety, health, and the environment. Making smart energy choices means understanding resources and their relative costs and benefits. Some energy sources have advantages for specific10 uses or locations. For example, fuels from petroleum are well suited for transportation because they pack a lot of energy in a small space and are easily transported and stored. Small hydroelectric installations are a good solution for supplying power or mechanical energy close15 to where it is used. Coal is widely used for power generation in many fast-developing countries - including China, India, and many others - because domestic supplies are readily available. Efficiency is an important factor in energy costs.20 How efficiently can the energy be produced, delivered, and used? How much energy value is lost in that process, and how much ends up being transformed into useful work? Industries that produce or use energy continually look for ways to improve efficiency, since this is a key to25 making their products morecompetitive. The ideal energy source - cheap, plentiful, and pollution-free - may prove unattainable in our lifetime, but that is the ultimate goal. The energy industry is continuing to improve its technologies and practices, to30 produce and use energy more efficiently and cleanly. Energy resources are often categorized as renewable or nonrenewable. Renewable energy resources are those that can be replenished quickly - examples are solar power,35 biomass, geothermal, hydroelectric, wind power, and fast-reaction nuclear power. They supply about seven percent of energy needs in the United States; theother 93 percent comes from nonrenewables. The two largest categories of renewable energy now in use in the U.S.40 are biomass - primarily wood wastes that are used by the forest products industry to generate electricity and heat - and hydroelectricity. Nonrenewable energy resources include coal, oil, natural gas, and uranium-235, which is used to fuel45 slow-reaction nuclear power. Projections of how long a nonrenewable energy resource will last depend on many changeable factors. These include the growth rate of consumption, and estimates of how much of the remaining resources can be economically recovered. New exploration50 and production technologies often increase theability of producers to locate and recover resources. World reserves of fossil energy are projected to last for many more decades - and, in the case of coal, for centuries.In: http://www.classroom-energy.org/teachers/energy_tour/pg5.html

     It now seems to me that what matters most in the majority
of organizations is to have reasonably intelligent, hard-working
managers who have a sense of pride and loyalty toward their
organization; who can get to the root of a problem and are inclined
toward action; who are decent human beings with a natural empathy
and concern for people; who possess humor, humility, and common
sense; and who are able to couple drive with stick-to-it-iveness* and
patience in the accomplishment of a goal.
     It is the ability to make positive things happen that most
distinguishes the successful manager from the mediocre or
unsuccessful one. It is far better to have dependable managers who
can make the right things happen in a timely fashion than to have
brilliant, sophisticated, highly educated executives who are excellent
at planning and analyzing, but who are not so good at implementing.
The most cherished manager is the one who says “I can do it,” and
then does.
     Many business schools continue to focus almost exclusively
on the development of analytical skills. As a result, these schools are
continuing to graduate large numbers of students who know a great
deal about analyzing strategies, dissecting balance sheets, and using
computers — but who still don’t know how to manage!
     As a practical matter, of course, schools can go only so far
in teaching their students to manage. Only actual work experience
will fully develop the kinds of managerial traits, skills, and virtues
that I have discussed here.

When I talk with librarians about thinking of themselves as designers, sometimes they demur. "Designer? I cant even draw a stick figure!" But you dont need to. Whether you know it or not, youre already a designer.

Every time librarians create a bookmark, decide to house a collection in a new spot, or figure out how a new service
might work, theyre making design decisions. This is what I like to call design by neglect or unintentional design. Whether library employees wear name tags is a design decision. The length of loan periods and whether or not you charge fines is a design decision. Anytime you choose how people will interact with your library, youre making a design decision. All of these decisions add up to create an experience, good or bad, for your patrons.

When we are mindful of our roles as library experience designers, we can make more informed design choices. This awareness can provide better experiences for our patrons and demonstrate that we care about them.

Really. People will notice, [CONJUNCTION] not necessarily consciously, if we [VERB] the time to think about them when were developing our services. The secret here is not to think of library patrons, users, or customers: we need to think of people. We need to consider their lives and what theyre trying to accomplish. This act, which can only be done by cultivating the skill of empathy, is the most important ? and perhaps the most difficult ? part of user experience design.

UN announces program to help hunger hot spots

A UN agency rolled out a $ 214 million program Tuesday to help 16 needy places hit hard by high prices for food and oil, amid a crisis already making it hard for aid groups to provide enough food for the worlds hungry.

The World Food Program said almost 1 billion poor people around the world are struggling to survive amid the higher prices. The agency is trying to reach those in critical need of assistance in Africa, Asia and the Caribbean.

"Food prices are not abating, and the worlds most vulnerable have exhausted their coping strategies", said Josette Sheeran, the agencys executive director. "Our action plan is targeted and customized to help the most vulnerable meet their urgent needs.
"The plan will provide assistance to groups such as pregnant women, undernourished children and people living in urban areas affected most by the food crisis.

The Rome-based agency also hopes to cut transportation costs and help support farmers in countries where emergency food can be bought locally.

But the agency already faces "obstacles" in procuring food, particularly when trying to buy supplies locally, spokeswoman Brenda Barton said.
"At the markets we have been buying food it has become just too expensive", Barton told The Associated Press by telephone. And she added: "a lot of markets just dont have any food to buy."

 Generation Y
By Sally Kane, About.com Guide

Born in the mid-1980"s and later, Generation Y legal professionals are in their 20s and are just entering the workforce. With numbers estimated as high as 70 million, Generation Y (also -1- as the Millennials) is the fastest growing segment of today"s workforce. As law firms compete for available talent, employers cannot ignore the needs, desires and attitudes of this vast generation. Below are a few common traits that define Generation Y.

Tech-Savvy: Generation Y grew up with technology and rely on it to perform their jobs better. Armed with BlackBerrys, laptops, cellphones and other gadgets, Generation Y is plugged-in 24 hours a day, 7 days a week. This generation prefers to communicate through e-mail and text messaging rather than face-to-face contact and -2- webinars and online technology to traditional lecture-based presentations.

Family-Centric: The fast-track has lost much of its appeal for Generation Y who is willing to trade high pay for fewer billable hours, flexible schedules and a better work/life balance. While older generations may view this attitude as narcissistic or lacking commitment, discipline and drive, Generation Y legal professionals have a different vision of workplace expectations and prioritize family over work.

Achievement-Oriented: Nurtured and pampered -3- parents who did not want to make the mistakes of the previous generation, Generation Y is confident, ambitious and achievement-oriented. They have high expectations of their employers, seek out new challenges and are not afraid to question authority. Generation Y wants meaningful work and a solid learning curve

Team-Oriented: As children, Generation Y participated in team sports, play groups and other group activities. They value teamwork and seek the input and affirmation of others. Part of a no-person-left-behind generation, Generation Y is loyal, committed and wants to be included and involved.

Attention-Craving: Generation Y craves attention in the forms of feedback and guidance. They appreciate being kept in the loop and seek frequent praise and reassurance. Generation Y may benefit greatly from mentors who can help guide and develop their young careers.
