The experience of "beauty" often involves an interpretation of some entity as being in balance and harmony with nature, which may lead to feelings of attraction and emotional well-being. Because this can be a subjective experience, it is often said that "beauty is in the eye of the beholder. There is evidence that perceptions of beauty are evolutionarily determined, that things, aspects of people and landscapes considered beautiful are typically found in situations likely to give enhanced survival of the perceiving human's genes.[3][4] Etymology[edit] The classical Greek noun for "beauty" was κάλλος, kallos, and the adjective for "beautiful" was καλός, kalos. Historical view of beauty[edit] Florence Cathedral and dome. Plato considered beauty to be the Idea (Form) above all other Ideas.[10] Aristotle saw a relationship between the beautiful (to kalon) and virtue, arguing that "Virtue aims at the beautiful Beauty is truth, truth beauty, —that is all.

Fire The ignition and extinguishing of a pile of wood shavings Slow motion fire sequence 1000 frame/s The fire maps show the locations of actively burning fires around the world on a monthly basis, based on observations from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. The colors are based on a count of the number (not size) of fires observed within a 1,000-square-kilometer area. Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Physical properties Chemistry Fires start when a flammable and/or a combustible material, in combination with a sufficient quantity of an oxidizer such as oxygen gas or another oxygen-rich compound (though non-oxygen oxidizers exist that can replace oxygen), is exposed to a source of heat or ambient temperature above the flash point for the fuel/oxidizer mix, and is able to sustain a rate of rapid oxidation that produces a chain reaction.

Bradley University: Body & Beauty Standards With images of ideal beauty bombarding us daily, it is easy to forget that standards of beauty are arbitrary and they vary greatly both from one culture to another and over time. Such variations in ideals of beauty often reflect the roles women and men are expected to fulfill in a given society. For instance, in contexts where women are valued mainly for their fertility—their ability to bear and nurture children—often full-bodied women with broad hips and ample breasts are considered the most beautiful. In societies such as Fiji, large bodies are a symbol of one’s status and power. But as social conditions and gender roles change, so do ideas about beauty. Why is the American body ideal for women so thin today? Does this tell us anything about the roles we expect men and women to fulfill? Can you think of any “plus-size” celebrities today?

Leadership Theories[edit] Early western history[edit] The trait theory was explored at length in a number of works in the 19th century. Most notable are the writings of Thomas Carlyle and Francis Galton, whose works have prompted decades of research.[4] In Heroes and Hero Worship (1841), Carlyle identified the talents, skills, and physical characteristics of men who rose to power. In Galton's Hereditary Genius (1869), he examined leadership qualities in the families of powerful men. Rise of alternative theories[edit] In the late 1940s and early 1950s, however, a series of qualitative reviews of these studies (e.g., Bird, 1940;[5] Stogdill, 1948;[6] Mann, 1959[7]) prompted researchers to take a drastically different view of the driving forces behind leadership. Reemergence of trait theory[edit] New methods and measurements were developed after these influential reviews that would ultimately reestablish the trait theory as a viable approach to the study of leadership. Attribute pattern approach[edit]

Male Bodies and Beauty throughout the ages | The Macaronis We have to acknowledge that in this day and age – as it has forever been – beauty matters. Our definition of beauty is based on the media saturation which we are bombarded with on a daily basis. For instance, the idea of tanned = gorgeous has only appeared recently — it would stand to reason that with all the lead-based paints and powder that was used, pale was beautiful as it indicated that you had no need to stand about in the sun all day. As a society, we perceive people who have traits which we consider admirable: self restraint, indefatigable dedication to an idea, sacrifice to epitomise the current standards of beauty – mirrored so closely in the way we view the working world. Personally, all that leaves me completely cold. why yes, that is a plastic knigget on a my little pony Of course, lacking a tardis, I can’t go back in time and drag examples of said bodies to parade before you. For the time periods, I’m shamelessly nicking the structure of “The List” from Speak Its Name.

Masculinity Masculinity is a set of qualities, characteristics or roles generally considered typical of, or appropriate to, a man. It can have degrees of comparison: "more masculine", "most masculine'". The opposite can be expressed by terms such as "unmanly" or epicene.[1] A near-synonym of masculinity is virility (from Latin vir, man). Constructs of masculinity vary across historical and cultural contexts. The dandy, for instance, was regarded as an ideal of masculinity in the 19th century, but is considered effeminate by modern standards.[2] Traditional masculine norms, as described in Dr. Nature versus nurture[edit] Hegemonic masculinity[edit] Direct competition of physical skill and strength is a feature of masculinity which appears in some form in virtually every culture on Earth. Traditional avenues for men to gain honor were that of providing adequately for their families and exercising leadership.[11] Connell has labelled the traditional male roles and privileges hegemonic masculinity.

How men's perfect body types have changed throughout history A precursor to the fop, the Macaronis were originally British young men who went abroad, fell in love with the Italian food "maccaroni" and the European style of dress. According to historian Geri Walton, the men would commonly order maccaroni to show off that they recently visited Italy and eventually got the nickname "macaronis." From the 1775 book Easy Phraseology, Joseph Baretti wrote "Strange, that this word has so much changed of its meaning in coming from Italy to England: that in Italy it should mean a block-head, a fool; and mean in England a man fond of pompous and affected dress!" They began to wear more fashionable and slightly feminine clothing. A trim figure was preferred as their many layers clung to the body. Basically, they were the hipsters of their day. Eventually, Macaronis became a laughing stock. People resented this womanly look and it soon fell out of fashion and placed a greater importance on looking properly masculine.

Injury The knee of a patient is examined with help of radiography after an injury. An injury is damage to a biological organism caused by physical harm.[1] Major trauma is injury that can potentially lead to serious outcomes. Classification[edit] The United States Bureau of Labor Statistics developed the Occupational Injury and Illness Classification System (OIICS). nature,part of body affected,source and secondary source, andevent or exposure. The OIICS was first published in 1992 and has been updated several times since.[2] The World Health Organization developed the International Classification of External Causes of Injury (ICECI). mechanism of injury,objects/substances producing injury,place of occurrence,activity when injured,the role of human intent, and additional modules. The Orchard Sports Injury Classification System (OSICS) is used to classify injuries to enable research into specific sports injuries.[4] By ultimate cause[edit] By modality[edit] By location[edit] By activity[edit]

DESDE LA PREHISTORIA AL S. XX | LOS CÁNONES DE BELLEZA A LO LARGO DE LA HISTORIA El cuerpo humano debía estar armónicamente proporcionado, utilizaban el puño como unidad de medida, así codificaron la estatura perfecta de las personas en 18 puños: 2 para el rostro, 10 desde los hombros hasta las rodillas y los 6 restantes para las piernas y los pies. En consecuencia, una mujer o un hombre eran “bellos” si medían 18 veces su propio puño y estaban debidamente proporcionados como establecía el canon. Según el canon de belleza egipcio una mujer debía ser delgada, con pequeños miembros pero de caderas anchas y pechos pequeños y torneados, solían ensalzar su belleza mediante joyas y bisutería. Su preocupación por mantener el cuerpo lo mas perfecto posible, les llevo a conocer muy bien la naturaleza para obtener de ella todos aquellos productos que les ayudase a conseguirlo. Los egipcios no se preocupan por su cuerpo ni más ni menos de lo que lo hacemos hoy en día. GRECIA (S. La belleza dependía de la intervención de Dios como consecuencia del auge del cristianismo. 1. 2. 3.

Risk Risk is the potential of losing something of value, weighed against the potential to gain something of value. Values (such as physical health, social status, emotional well being or financial wealth) can be gained or lost when taking risk resulting from a given action, activity and/or inaction, foreseen or unforeseen. Risk can also be defined as the intentional interaction with uncertainty. Risk perception is the subjective judgment people make about the severity of a risk, and may vary person to person. Any human endeavor carries some risk, but some are much riskier than others.[1] Definitions[edit] Firefighters at work Risk can be defined in a variety of ways. Basic definitions[edit] The probability of something happening multiplied by the resulting cost or benefit if it does. International Organization for Standardization[edit] The ISO 31000 (2009) / ISO Guide 73:2002 definition of risk is the 'effect of uncertainty on objectives'.

Sexualidad y erotismo en la Prehistoria | Revista Internacional de Andrología La investigación arqueológica y antropológica permite interpretar de forma objetiva el modo de vida de nuestros ancestros, y el estudio del arte paleolítico proporciona muchas pistas acerca de cómo los individuos de aquella época interpretaban el entorno y se comportaban. No sólo su interés por la reproducción, sino también su sexualidad quedan patentes en algunas de sus obras. No cabe duda de que la reproducción humana durante la última glaciación permitió la supervivencia de la especie en lo que constituye uno de los mejores ejemplos de nuestra capacidad adaptativa. Hace 25-15 mil años (ka), en plena última glaciación Würm, las condiciones climáticas fueron extraordinariamente duras. El clima era muy frío y seco, aunque hubo algunos períodos cortos en los que estas condiciones mejoraron. En aquella época la población humana era muy limitada. El arte prehistórico nace, posiblemente, como una respuesta sicológica a la ansiedad generada por un entorno misterioso y casual. Figura 1. Dr.

Blood Human blood fractioned by centrifugation. Plasma (upper layer), buffy coat (middle, white colored layer) and erytrocite layer (bottom) can be seen. Blood circulation: Red = oxygenated Blue = deoxygenated Human blood magnified 600 times Frog blood magnified 600 times Fish blood magnified 600 times In vertebrates, it is composed of blood cells suspended in blood plasma. Vertebrate blood is bright red when its hemoglobin is oxygenated. Jawed vertebrates have an adaptive immune system, based largely on white blood cells. Medical terms related to blood often begin with hemo- or hemato- (also spelled haemo- and haemato-) from the Greek word αἷμα (haima) for "blood".
