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 environmentally effected 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 practiced pa ...

Rendille People
The Rendille (also known as Rendille, Reendile, Rendili, Randali, Randile, and Randille) are a Cushitic ethnic group inhabiting the 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 the Great Lakes after splitting off from the Cushitic-speaking peoples in the Horn region, following wide population expansions by various Nilotic and Bantu ethnic groups. Traditionally, they have been nomadic pastoralists, tending camels, sheep, goats and cattle. The camels were generally kept in the northern parts of their territory and the cattle in the southern section. The Rendille traditionally practice infibulation. This practice has its origins in Ancient Egypt which is well documented. According to Grassivaro-Gallo and Viviani, some people believe the custom was brought to the Horn of Africa from the Arabian Peninsula during antiquity. History Also known as the � ...

Kenya
Kenya, officially the Republic of Kenya, is a country located in East Africa. With an estimated population of more than 52.4 million as of mid-2024, Kenya is the 27th-most-populous country in the world and the 7th most populous in Africa. Kenya's capital and largest city is Nairobi. Its second-largest and oldest city is Mombasa, a major port city located on Mombasa Island. Other major cities within the country include Kisumu, Nakuru & Eldoret. Going clockwise, Kenya is bordered by South Sudan to the northwest (though much of that border includes the disputed Ilemi Triangle), Ethiopia to the north, Somalia to the east, the Indian Ocean to the southeast, Tanzania to the southwest, and Lake Victoria and Uganda to the west. Kenya's geography, climate and population vary widely. In western, rift valley counties, the landscape includes cold, snow-capped mountaintops (such as Batian, Nelion and Point Lenana on Mount Kenya) with vast surrounding forests, wildlife and ...

Samburu People
The Samburu are a Nilotic peoples, Nilotic people of north-central Kenya. Traditionally, they are semi-nomadic pastoralists who primarily herd cattle but also keep sheep, goats and camels. They refer to themselves as Lokop or Loikop, a term with varied interpretations among the Samburu. Some believe it means "owners of the land" ("lo" meaning ownership and "nkop" meaning land) while others have different interpretations. The Samburu speak the Samburu dialect of the Maasai language, Maa language, a Nilotic languages, Nilotic language which is also spoken by 22 other sub tribes of the Maa community commonly known as the Maasai people, Maasai. Some suggest that the Samburu are a distinct tribe separate from the Maasai, a view that some Samburu people accept today. Samburu National Reserve is one of the well known wildlife conservation areas in Kenya. Within the Maa community of Kenya and Tanzania, the Samburu sub-tribe is the third largest, following the Kisonko (Isikirari) of ...

Dopamine
Dopamine (DA, a contraction of 3,4-dihydroxyphenethylamine) is a neuromodulatory molecule that plays several important roles in cells. It is an organic chemical of the catecholamine and phenethylamine families. It is an amine synthesized by removing a carboxyl group from a molecule of its precursor chemical, L-DOPA, which is 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. The brain includes several distinct dopamine pathways, one of which plays a major role in the motivational component of reward-motivated behavior. The anticipation of most types of rewards increases the level of dopamine in the brain, and many addictive drugs increase dopamine release or block its reuptake into neurons following release. Other brain dopamine pathways are involved in motor control and in controllin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ADHD
Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterised by symptoms of inattention, hyperactivity, impulsivity, and emotional dysregulation that are excessive and pervasive, impairing in multiple contexts, and developmentally inappropriate. ADHD symptoms arise from executive dysfunction. Impairments resulting from deficits in self-regulation such as time management, inhibition, task initiation, and sustained attention can include poor professional performance, relationship difficulties, and numerous health risks, collectively predisposing to a diminished quality of life and a reduction in life expectancy. As a consequence, the disorder costs society hundreds of billions of US dollars each year, worldwide. It is associated with other mental disorders as well as non-psychiatric disorders, which can cause additional impairment. While ADHD involves a lack of sustained attention to tasks, inhibitory deficits also can lead to diffic ... [...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. However, these estimates may be inaccurate as females tend to have fewer symptoms, as identified in the DSM-IV, and thus tend to be under-diagnosed due to these sex differences in predicting ADHD. When diagnosed via the ICD-10 criteria, hyperkinetic disorder Hyperkinetic disorder was a neuropsychiatric condition that was thought to emerge in early childhood. Its features included an enduring pattern of severe, developmentally-inappropriate symptoms of inattention, hyperactivity, and impulsivity acr ... (the ICD-10 term for severe ADHD) gives rates between 1 and 2 percent in this age group. Cited so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
