Somatosensory system

The somatosensory system, also known as somatic senses, touch or tactile perception, is a complex sensory system. It is considered one of the five traditional senses. It is made up of a number of different receptors, including thermoreceptors, photoreceptors, mechanoreceptors and chemoreceptors. It also comprises essential processing centres, or sensory modalities, such as proprioception, mechanoreception (touch), thermoception (temperature), and nociception (pain). The sensory receptors cover the skin and epithelial tissues, skeletal muscles, bones and joints, internal organs, and the cardiovascular system.

Somatic senses are sometimes referred to as somesthetic senses, with the understanding that somesthesis includes touch, proprioception and (depending on usage) also haptic perception.

Processing primarily occurs in the primary somatosensory area in the parietal lobe of the cerebral cortex: information is sent from the receptors via sensory nerves, through tracts in the spinal cord and finally into the brain.

Major

Major is a military rank of commissioned officer, with corresponding ranks existing in many military forces. When used unhyphenated, in conjunction with no other indicators, the rank is just senior to that of an army captain and right below the rank of lieutenant colonel. It is considered the most junior of the field officer ranks.

Majors are typically assigned as specialized executive or operations officers for battalion-sized units of 300 to 1,200 soldiers. In some militaries, notably France and Ireland, the rank of major is referred to as commandant, while in others it is known as captain-major. It is also used in some police forces and other paramilitary rank structures, such as the New York State Police, New Jersey State Police and several others. As a police rank, Major roughly corresponds to the UK rank of Superintendent.

When used in hyphenated or combined fashion, the term can also imply seniority at other levels of rank, including general-major or major general, denoting a mid-level general officer, and sergeant major, denoting the most senior NCO of a military unit. The term Major can also be used with a hyphen to denote the leader of a military band such as in pipe-major or drum-major.

Hard Times

Hard Times – For These Times (commonly known as Hard Times) is the tenth novel by Charles Dickens, first published in 1854. The book appraises English society and highlights the social and economic pressures of the times.

Background

Hard Times is unusual in several respects. It is by far the shortest of Dickens' novels, barely a quarter of the length of those written immediately before and after it. Also, unlike all but one of his other novels, Hard Times has neither a preface nor illustrations. Moreover, it is his only novel not to have scenes set in London. Instead the story is set in the fictitious Victorian industrial Coketown, a generic Northern English mill-town, in some ways similar to Manchester, though smaller. Coketown may be partially based on 19th-century Preston.

One of Dickens's reasons for writing Hard Times was that sales of his weekly periodical, Household Words, were low, and it was hoped the novel's publication in instalments would boost circulation – as indeed proved to be the case. Since publication it has received a mixed response from critics. Critics such as George Bernard Shaw and Thomas Macaulay have mainly focused on Dickens's treatment of trade unions and his post–Industrial Revolution pessimism regarding the divide between capitalist mill owners and undervalued workers during the Victorian era. F. R. Leavis, a great admirer of the book, included it--but not Dickens' work as a whole--as part of his Great Tradition of English novels.
