Researchers conclude that only about five percent of adults in America have the winter variant of SAD‚ and less than one percent have the summer variant (Khazan). NAMI defines the classic winter form of SAD as “recurrent

Industry: Friend or Foe? The restaurant industry can be a fickle friend. Business trends directly with the economy and is linked with a dizzying amount of other factors‚ enough to make any manager go crazy. Yet at the same time the industry is lucrative and therefore enticing. The industry has been a contributing factor in the slow recovery from economic recession and is showing growth in sales (Stensson‚ 2011). Specifically‚ the fast food industry if projected to grow at a slightly higher

Sample Paper Population definitionSuccessful statistical practice is based on focused problem definition. In sampling‚ this includes defining the population from which our sample is drawn. A population can be defined as including all people or items with the characteristic one wishes to understand. Because there is very rarely enough time or money to gather information from everyone or everything in a population‚ the goal becomes finding a representative sample (or subset) of that population.

Pandemic influenza occurs when a new or novel strain of influenza virus capable of spreading easily from person to person emerges. Since it is a new strain‚ there is often little or no immunity to it and it may spread rapidly‚ creating a global outbreak.

Statistical mechanics or statistical thermodynamics[note 1] is a branch of physics that applies probability theory‚ which contains mathematical tools for dealing with large populations‚ to the study of the thermodynamic behavior of systems composed of a large number of particles. Statistical mechanics provides a framework for relating the microscopic properties of individual atoms and molecules to the macroscopic bulk properties of materials that can be observed in everyday life‚ therefore explaining
