"What exactly is the problem with our roads? Is it maintenance, is it workmanship of contractors? Why don't our roads have a long lifespan, "Obasanjo queried a team from the ministry of works, housing and urban development.The former president urged the ministry in charge of road construction and maintenance to pay more attention on awards of contracts to companies that are incapable of delivering roads with long lifespan. "The roads in Nigeria do not justify the investments put into it," Obasanjo said.
According to the Minister of Works, Dr. Hassan, close to $ 48 million was set aside in the 2008 budget for road construction and maintenance but the roads are still in bad shapeObasanjo noted that the deterioration of roads was worsened by the collapse of the rail system and inland water ways is responsible for the burden of haulage of all industrial, agricultural, petroleum and commercial goods and services to road network.
Reaction time techniques were used to examine the role of attention in the construction and maintenance of expectancies. In Experiment I, a primed letter matching task, expectancies were observed through a delay (cost) in responding to misprimed letter arrays. A secondary probe task was interpolated between prime and array letters on some of the trials, with attentional demands inferred from delayed responding to probes. By varying the amount of time between onset of the prime and either a probe or letter array, it was found that there is attentional involvement (as reflected in probe inhibition) prior to the observation of expectancies (as reflected in letter matching cost). It was also found that the interpolation of an attention-demanding probe task did not entirely disrupt primed expectancies. Experiment II found that an expectancy persists even when an interpolated distractor task signals that the expectancy is no longer valid. These expectancies were found to decay as a function of time. The implications of these results for attention allocation and memory activation views of expectancy were discussed.
Anyone who has ever wandered the showroom of a car dealership knows the difference between the base model and the one with all the latest options and extras. And they sure know which one is more fun to drive.A tennis court can be like that. It can include just the basic necessities, or it can involve spending a little more and choosing those things that punch up the experience a few notches. Making choices can be pretty confusing. You might have thought that once you've selected a court surface, the rest of the decisions flow naturally. Well, yes and no. The choice of a surface (acrylic-coated asphalt or concrete, cushioned, sand-filled turf, modular, clay or fast-dry material) does tend to dictate some of the types of options and extras a court will have. The type of court also will dictate some choices. A residential court, for example, may require amenities designed to make the court an activity and social center for the family, such as a seating area or outdoor kitchen. A club may have courts designed specifically for teaching and others tailored toward competition.
Do you need a ball machine? How about a shade shelter? Would changing booths come in handy? How about lights and divider netting? Do you need a practice wall? How about a trash can to help keep things neat and clean? The answers depend on your intended use, your budget, and your preferences. It's easy to get carried away. So what is the best way to figure out what you need and what you want versus what you can afford? Simple. Just think of it the same way as if you were buying a car. All you need is a legal pad (or your computer or PDA) and a little time to think. Oh, and most important of all, a long conversation with the person who builds your tennis court.
