  • Popular American films penetrate nearly every aspect of contemporaryWestern life, and to an only somewhat lesser degreemost all cultures of the world. Historically, there are powerful sociological, cultural, economic, and even political reasons for this, but we would also argue thatHollywood-style filmhas evolved so that filmmakers havemore control over the attention of filmgoers (Smith 2006) and, in essence, the humanmind. One source of evidence concerns the changing pattern of shot lengths.

  • When there are frictions in setting nominal wages, however, a riseintherealwagerequiresthatinflationbeallowedtodriftdown.Theinflation targeting central bank, seeing this drift down in inflation, cuts the interest rate to keep inflation on target. In our model, this cut in the interest rate triggers a credit boom and makes the economic expansion much bigger than is socially optimal. In a situation like this, a central bank that ‘leans against the wind’ when credit expands sharply would raise welfare by reducing the magnitude of the boom-bust cycle....

  • There is more direct evidence of domestication of the South American camelids than of the old world ones. The archaeological evidence suggests that llama and alpaca were domesticated at very high altitudes of 4000 to 5000 m in the Andes of southern Peru and western Bolivia. An approximate time of first domestication would be about 6000 years BP. This period has been based on changes in the type of molar teeth and the increasing numbers of bones of young as compared to old animals found at archaeological sites. ...

  • Scientists do not know exactly what causes most adrenal cortical tumors. Over the past few years, they have made great progress in understanding how certain changes in a person's DNA can cause cells in the adrenal gland to become cancerous. DNA is the molecule that carries the instructions for nearly everything our cells do. We usually look like our parents because they are the source of our DNA. However, DNA affects more than the way we look. It also determines our risk for developing certain diseases, including some types of cancer.

  • Development initiatives in the past have emphasized genetic improvement, usually through the introduction of exotic genes, arguing that improved feed would have no effect on indigenous birds of low genetic potential. There is a growing awareness of the need to balance the rate of genetic improvement with improvement in feed availability, health care and management. There is also an increased recognition of the potential of indigenous breeds and their role in converting locally available feed resources into sustainable production.

  • If camels and other stock can be based far away from a water source, the total area available for grazing is greatly increased, the stocking rate can be lowered and the dangers of environmental degradation are reduced. In simple terms, a doubling of the interval between successive visits to water results in a four-fold increase in the area available for pasture, with a corresponding reduction in grazing pressure. More especially, the time period between successive waterings has an important bearing on the carrying capacity and the degradation risk of a given area.

  • Nutrition is taught in each and every grade from kindergarten through tenth grade in over 90 percent of all public schools; it is taught in eleventh and twelfth grades in over 80 percent of schools (figure 1 and table 2). These statistics do not reflect the proportion of students participating at each grade level, but give a broad overview of nutrition education offerings. The percent of schools with nutrition education requirements is substantially lower at each grade level than the percent of schools that teach nutrition.

  • The retirement crisis is directly attributable to the failure of the “three-legged stool” of retirement security. Traditionally, defined benefit pension plans (“pensions”), personal savings, and Social Security were seen as the three pillars creating a solid foundation for our retirement system. Each should play an important role in supporting people in old age. However, the stool, never sturdy, has become increasingly wobbly as pensions have disappeared and the middle class is finding it harder and harder to save. ...

  • The cancer registry is an essential part of any rational programme of can- cer control. Its data can be used in a wide variety of areas of cancer control ranging from etiological research, through primary and secondary preven- tion to health-care planning and patient care. Although most cancer reg- istries are not obliged to do more than provide the basis for such uses of the data, they possess the potential for developing and supporting important research programmes making use of the information they collect....

  • The hazardous and harmful use of alcohol is a major global contributing factor to death, disease and injury: to the drinker through health impacts, such as alcohol dependence, liver cirrhosis, cancers and injuries; and to others through the dangerous actions of intoxicated people, such as drink– driving and violence or through the impact of drinking on fetus and child development. The harmful use of alcohol results in approximately 2.5 million deaths each year, with a net loss of life of 2.

  • Thus, ultrafine dusts of the same dimensions as nanoparticles mainly penetrate the body via inhalation and are deposited in the lungs. A portion of these dusts can be distributed directly to the brain via the olfactory nerves. The lungs do not necessarily succeed in totally eliminating these undesirable particles, which then cause pulmonary inflammation. This can lead to the development of lung diseases specific to the nature of the dusts that caused them.

  • Thus, in living cells, the rates of anterograde and retrograde transport between the two organelles appear to have a substantial effect on the morphology of the Golgi. The effect of the balance between anterograde and retrograde transport on the morphology of the ER remains to be explored. Recently, increasing evidence has suggested that alteration in Golgi morphology during mitosis is not a passive process but rather an active one, which is highly coordinated with entry into mitosis and its progression.

  • The life cycle of the retrovirus consist of several steps. It begins with the binding of the viral envelope to cellular receptors, which enables fusion of the viral envelope with the cellular membrane. Consequently, the viral particle is uncoated, liberating the viral core into the cell cytoplasm. The viral DNA is reverse transcribed to DNA. Then, the viral DNA is transported to the nucleus where it is integrated into the host cell’s genome. From there, viral DNA is transcribed to RNA, some of which is translated to proteins.

  • and gait is mostly derived from studies that measured and reported EF as a composite score [12,18,19]. Relatively few studies have focused on the age-related deficits in specific components of executive function and most of these studies were based on a traditional set of tests of executive function, without detailing specific components. The conclusions drawn from these studies might, therefore, be limited by their methodologies. The putative executive measures might not load on a single executive construct, and might overlap with each other [20,21].

  • The tax-exempt money market is more complex than the taxable money market. That’s largely because of a supply-and-demand imbalance for very short-term municipal securities. There’s a high level of demand for these issues—much of it coming from individuals who want to minimize their tax bill by placing their cash in a tax-exempt money market mutual fund. But supply is limited.
