Through referenced literature and examples, examine the range of theories of what an entrepreneur is and how they contribute to the economy and society - Essay Example the term is applied, certain elements are constant: entrepreneurs are persons of certain psychological qualities and unique abilities who, through these qualities, contribute wealth and energy to an economy and social benefits beyond business. There are a whole range of theories as to what makes an entrepreneur. Regarding the assertion that entrepreneurs are born, not made...Shane (2010) asserts this may be only half true if one is speaking about genetic traits. One of the more modern empirical investigations was done by Collins and Moore and published in their exceptional analysis in The Enterprising Man. (delete words) Seeking to prove their theory that entrepreneurs represents certain psychological traits, they employed the Thematic Apperception Tests (TAT) test. The subject, presented with a set of cards with human figures in a variety of settings, creates a story including elements describing the event shown; what has led up to it; what the characters in the picture are feeling and thinking; and the outcome of the event. The test assumes certain results about the subject’s personality in relationship to entrepreneurship—workaholics rarely every satisfied; patronizing with subordinates; suspect and rejecting of authority—that within the Collins and Moore psychological profile theory represents early childhood relationships with adults in the entrepreneurs life. (Roberts, 1991: 50). Throughout other studies, however, while there appears to be a clear relationship between entrepreneurship and achievement motivation across a number of measurement instruments (Edwards Personal Preference Scale, the Mehrabian Scale, and the TAT (1) Sexton and Bowman (1986) found inconsistencies that challenge the blind acceptance of this theory, and that ‘students and nonstudents (entrepreneurs, potential entrepreneurs, and nonentrepreneurs) differ on a variety of characteristics which are supposed to be stable across time and situations according to personality

ALS (amyotrophic lateral sclerosis) Term Paper Example | Topics and Well Written Essays - 1500 words

ALS (amyotrophic lateral sclerosis) - Term Paper Example This may cause paralysis at the later stages of the disease. If a muscle is affected by death of its motor neurons, this means that it does not get nourishment. Therefore, the muscle wastes away (atrophy) leading to hardening of the muscle (sclerosis). The main characteristic of this disorder is the destruction and death of the motor neurons in the brain and spinal cord in which before their destruction they develop inclusions in their structures-the axon and cell bodies that are rich in protein. The proteins are believed to be as a result of a problem in the degeneration of protein and these inclusions have a substance called ubiquitin and this combines with one of the proteins associated with ALS for example TAR DNA binding protein. (Murray, 2006) As the motor neurons get destroyed in the lateral and anterior parts of the spinal cord, the neurons are replaced by astrocytes that cause sclerosis. The degeneration of the upper motor neurons that is located in the cortex of the brain results in paralysis, increased reflexes and stiffness of the affected muscles. The degeneration of the motor neurons that is located in the in stem and the horn-like part at the anterior of the spinal cord results in flaccid paralysis, weakness of muscles and atrophy of the muscles, decreased reflexes and decrease in the muscle tone. The initial symptoms of this disorder are generally, muscle weakness affecting mostly those of the arms and legs, cramping, difficulty in swallowing, problems in speech and breathing and stiffness of the muscle that has been affected. (Murray, 2006) When the clinical manifestation is first noticed in the arms and legs, it is referred to as limb-onset ALS whereas if the symptoms affect the speech first it is called bulbar-onset ALS. The bulbar symptoms include difficulty in speech, difficulty in swallowing, drooling, atrophy and fasciculation of the tongue. When the upper motor neurons are affected, the disorder is
