Ariaal
The Ariaal are northern Kenyan pastoralists. They claim descent from cattle-owning Samburu who captured significant herds of camels and learned how to manage them from their eastern neighbours, the Rendille. This led them to adopt the Rendille culture, language, and other Rendille practices, such as monogamy. Before Kenya independence, the separation between the cattle and camel economies was vividly reflected in the division between an Ariaal elder's senior wife, whose family would be reared as Ariaal, and his junior wives who lived with his cattle as Samburu. In effect, such elders continued to straddle the boundary between monogamous camel-owning Ariaal and polygynous cattle-owning Samburu, speaking both languages and participating in both cultures. An Ariaal person killing a lion is highly respected. Ethnological studies They have been the subject of much study by anthropologists, especially Elliot Fratkin. More recent work has been conducted by Bettina Shell-Duncan, Benja ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pastoralism
Pastoralism is a form of animal husbandry where domesticated animals (known as "livestock") are released onto large vegetated outdoor lands (pastures) for grazing, historically by nomadic people who moved around with their herds. The animal species involved include cattle, camels, goats, yaks, llamas, reindeer, horses and sheep. Pastoralism occurs in many variations throughout the world, generally where environmental characteristics such as aridity, poor soils, cold or hot temperatures, and lack of water make crop-growing difficult or impossible. Operating in more extreme environments with more marginal lands means that pastoral communities are very vulnerable to the effects of global warming. Pastoralism remains a way of life in many geographic areas, including Africa, the Tibetan plateau, the Eurasian steppes, the Andes, Patagonia, the Pampas, Australia and many other places. , between 200 million and 500 million people globally practised pastoralism, and 75% ...

Rendille People
The Rendille (also known as Rendille, Reendile, Rendili, Randali, Randile, and Randille) are a Cushitic-speaking ethnic group inhabiting the northern Eastern Province of Kenya. Etymology The ethnonym ''Rendille'' translates as "Holders of the Stick of God". Overview The Rendille are believed to have originally migrated down into the Great Lakes after splitting off from the Somali people in the Horn region, following a southward population expansions by the Oromo and the Somalis. Traditionally, they are nomadic pastoralists, tending camels, sheep, goats and cattle. The camels are generally kept in the northern part of their territory and the cattle in the southern section. Additionally, the Rendille traditionally practice infibulation. This practice has it’s origins in Ancient Egypt which is well documented. Also, according to Grassivaro-Gallo and Viviani (1992), some believe the custom was first brought to the Horn region from the Arabian peninsula during antiquity, and was ...

Samburu People
The Samburu are a Nilotic people of north-central Kenya. Samburu are semi-nomadic pastoralists who herd mainly cattle but also keep sheep, goats and camels. The name they use for themselves is Lokop or Loikop, a term which may have a variety of meanings which Samburu themselves do not agree on. Many assert that it refers to them as "owners of the land" ("lo" refers to ownership, "nkop" is land) though others present a very different interpretation of the term. Samburu speak the Samburu dialect of the Maa language, which is a Nilotic language. The Maa language is also spoken by other 22 sub tribes of the Maa community otherwise known as the Maasai. Many Western anthropologists tried to carve out and create the Samburu tribe as a community of its own, unaffiliated to its parent Maasai community, a narrative that seems that many Samburu people today hold. There are many game parks in the area, one of the most well known is Samburu National Reserve. The Samburu sub tribe is the third ...

Dopamine
Dopamine (DA, a contraction of 3,4-dihydroxyphenethylamine) is a neuromodulatory molecule that plays several important roles in cells. It is an organic compound, organic chemical of the catecholamine and phenethylamine families. Dopamine constitutes about 80% of the catecholamine content in the brain. It is an amine synthesized by removing a carboxyl group from a molecule of its precursor (chemistry), precursor chemical, L-DOPA, which is biosynthesis, synthesized in the brain and kidneys. Dopamine is also synthesized in plants and most animals. In the brain, dopamine functions as a neurotransmitter—a chemical released by neurons (nerve cells) to send signals to other nerve cells. Neurotransmitters are synthesized in specific regions of the brain, but affect many regions systemically. The brain includes several distinct dopaminergic pathway, dopamine pathways, one of which plays a major role in the motivational component of reward system, reward-motivated behavior.

ADHD
Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterised by excessive amounts of inattention, hyperactivity, and impulsivity that are pervasive, impairing in multiple contexts, and otherwise age-inappropriate. ADHD symptoms arise from executive dysfunction, and emotional dysregulation is often considered a core symptom. In children, problems paying attention may result in poor school performance. ADHD is associated with other neurodevelopmental and mental disorders as well as some non-psychiatric disorders, which can cause additional impairment, especially in modern society. Although people with ADHD struggle to focus on tasks they are not particularly interested in completing, they are often able to maintain an unusually prolonged and intense level of attention for tasks they do find interesting or rewarding; this is known as hyperfocus. The precise causes of ADHD are unknown in the majority of cases. Genetic factors play an import ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epidemiology Of Attention Deficit Hyperactive Disorder
Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder characterized by difficulty focusing attention, hyperactivity, and impulsive behavior. Treatments generally involve behavioral therapy and/or medications (stimulants and non-stimulants). ADHD is estimated to affect about 6 to 7 percent of people aged 18 and under when diagnosed via the DSM-IV criteria. When diagnosed via the ICD-10 criteria, hyperkinetic disorder (the ICD-10 term for severe ADHD) gives rates between 1 and 2 percent in this age group. Cited source of Cowen (2012): Children in North America appear to have a higher rate of ADHD than children in Africa and the Middle East - however, this may be due to differing methods of diagnosis used in different areas of the world. If the same diagnostic methods are used rates are more or less the same between countries. Africa In 2020, a meta-analysis of studies found that 7.47% of children and adolescents across Africa have ADHD. ADHD was found mor ...
