Malaise (band)
As a medical term, malaise is a feeling of general discomfort, uneasiness or lack of wellbeing and often the first sign of an infection or other disease. The word has existed in French since at least the 12th century. The term is often used figuratively in other contexts, in addition to its meaning as a general state of angst or melancholy. Cause Malaise is a non-specific symptom and can be present in the slightest ailment, such as an emotion (causing fainting, a vasovagal response) or hunger (light hypoglycemia), to the most serious conditions (cancer, stroke, heart attack, internal bleeding, etc.). Malaise expresses a patient's uneasiness that "something is not right" that may need a medical examination to determine the significance. Malaise is thought to be caused by the activation of an immune response, and the associated pro-inflammatory cytokines. Figurative use "Economic malaise" refers to an economy that is stagnant or in recession (compare depression). The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emotion
Emotions are mental states brought on by neurophysiological changes, variously associated with thoughts, feelings, behavioral responses, and a degree of pleasure or displeasure. There is currently no scientific consensus on a definition. Emotions are often intertwined with mood, temperament, personality, disposition, or creativity. Research on emotion has increased over the past two decades with many fields contributing including psychology, medicine, history, sociology of emotions, and computer science. The numerous theories that attempt to explain the origin, function and other aspects of emotions have fostered more intense research on this topic. Current areas of research in the concept of emotion include the development of materials that stimulate and elicit emotion. In addition, PET scans and fMRI scans help study the affective picture processes in the brain. From a mechanistic perspective, emotions can be defined as "a positive or negative experience that is as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malaise Era
Malaise era is a term describing U.S.-market cars from roughly 1973 to 1983. The U.S. federal government released several mandates to reduce pollution and improve the fuel efficiency and safety of cars in this era, which while successful, ultimately resulted in the death of the 1960s-style American muscle car, a marked drop in performance in most American vehicles, and a change in visual styling away from 1960s design cues to generally less popular stylings in the 1970s. Origin of the term The term "malaise era", coined by journalist Murilee Martin, refers to U.S. President Jimmy Carter's malaise speech in which he discussed America's failure to deal with the 1979 oil crisis. Martin claimed the era began in 1973, when the U.S. government released new crash bumper regulations, and ended in 1983, when the Ford Mustang saw a significant performance increase after almost a decade of low performance. The term has since entered wider use, being seen in numerous automotive blogs as w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herman Kahn
Herman Kahn (February 15, 1922 – July 7, 1983) was a founder of the Hudson Institute and one of the preeminent futurists of the latter part of the twentieth century. He originally came to prominence as a military strategist and systems theorist while employed at the RAND Corporation. He became known for analyzing the likely consequences of nuclear war and recommending ways to improve survivability, making him one of the historical inspirations for the title character of Stanley Kubrick's classic black comedy film satire ''Dr. Strangelove''.Paul Boyer, 'Dr. Strangelove' in Mark C. Carnes (ed.), ''Past Imperfect: History According to the Movies'', New York, 1996. In his commentary for ''Fail Safe'', director Sidney Lumet remarked that the Professor Groeteschele character is also based on Herman Kahn. Kahn's theories contributed heavily to the development of the nuclear strategy of the United States. Background Kahn was born in Bayonne, New Jersey, the son of Yetta (née Kosl ...

Depression (economics)
An economic depression is a period of carried long-term economical downturn that is result of lowered economic activity in one major or more national economies. Economic depression maybe related to one specific country were there is some economic crisis that has worsened but most often reflexes historically the American Great Depression and similar economic status that may be recognized as existing at some country, several countries or even in many countries. It is often understood in economics that economic crisis and the following recession that maybe named economic depression are part of economic cycles where slowdown of economy follows the economic growth and vice versa. It is a result of more severe economic problems or a ''downturn'' than the economic recession, recession itself, which is a slowdown in economic activity over the course of the normal business cycle of growing economy. Economic depressions maybe also characterized by their length or duration, and maybe showing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recession
In economics, a recession is a business cycle contraction when there is a general decline in economic activity. Recessions generally occur when there is a widespread drop in spending (an adverse demand shock). This may be triggered by various events, such as a financial crisis, an external trade shock, an adverse supply shock, the bursting of an economic bubble, or a large-scale Anthropogenic hazard, anthropogenic or natural disaster (e.g. a pandemic). In the United States, a recession is defined as "a significant decline in economic activity spread across the market, lasting more than a few months, normally visible in real GDP, real income, employment, industrial production, and wholesale-retail sales." The European Union has adopted a similar definition. In the United Kingdom, a recession is defined as negative economic growth for two consecutive quarters. Governments usually respond to recessions by adopting expansionary macroeconomic policies, such as monetary policy, incr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economic Malaise
Economic stagnation is a prolonged period of slow economic growth (traditionally measured in terms of the GDP growth), usually accompanied by high unemployment. Under some definitions, "slow" means significantly slower than potential growth as estimated by macroeconomists, even though the growth rate may be nominally higher than in other countries not experiencing economic stagnation. Secular stagnation theory The term "secular stagnation" was originally coined by Alvin Hansen in 1938 to "describe what he feared was the fate of the American economy following the Great Depression of the early 1930s: a check to economic progress as investment opportunities were stunted by the closing of the frontier and the collapse of immigration". Warnings similar to secular stagnation theory have been issued after all deep recessions, but they usually turned out to be wrong because they underestimated the potential of existing technologies.Pagano and Sbracia (2014"The secular stagnation hypo ...

Cytokines
Cytokines are a broad and loose category of small proteins (~5–25 kDa) important in cell signaling. Cytokines are peptides and cannot cross the lipid bilayer of cells to enter the cytoplasm. Cytokines have been shown to be involved in autocrine, paracrine and endocrine signaling as immunomodulating agents. Cytokines include chemokines, interferons, interleukins, lymphokines, and tumour necrosis factors, but generally not hormones or growth factors (despite some overlap in the terminology). Cytokines are produced by a broad range of cells, including immune cells like macrophages, B lymphocytes, T lymphocytes and mast cells, as well as endothelial cells, fibroblasts, and various stromal cells; a given cytokine may be produced by more than one type of cell. They act through cell surface receptors and are especially important in the immune system; cytokines modulate the balance between humoral and cell-based immune responses, and they regulate the maturation, growth, and resp ...

Internal Bleeding
Internal bleeding (also called internal hemorrhage) is a loss of blood from a blood vessel that collects inside the body. Internal bleeding is usually not visible from the outside. It is a serious medical emergency but the extent of severity depends on bleeding rate and location of the bleeding (e.g. head, torso, extremities). Severe internal bleeding into the chest, abdomen, retroperitoneal space, pelvis, and thighs can cause hemorrhagic shock or death if proper medical treatment is not received quickly. Internal bleeding is a medical emergency and should be treated immediately by medical professionals. Signs and symptoms At first, there may be no symptoms of internal bleeding. If an organ is damaged and it bleeds, it can be painful. Over time, internal bleeding can cause low blood pressure (hypotension), increased heart rate (tachycardia), increased breathing rate (tachypnea), confusion, drowsiness, and loss of consciousness. A patient may lose more than 30% of their blood v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heart Attack
A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops to the coronary artery of the heart, causing damage to the heart muscle. The most common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck or jaw. Often it occurs in the center or left side of the chest and lasts for more than a few minutes. The discomfort may occasionally feel like heartburn. Other symptoms may include shortness of breath, nausea, feeling faint, a cold sweat or feeling tired. About 30% of people have atypical symptoms. Women more often present without chest pain and instead have neck pain, arm pain or feel tired. Among those over 75 years old, about 5% have had an MI with little or no history of symptoms. An MI may cause heart failure, an irregular heartbeat, cardiogenic shock or cardiac arrest. Most MIs occur due to coronary artery disease. Risk factors include high blood pressure, smoking, diabetes, lack of e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stroke
A stroke is a medical condition in which poor blood flow to the brain causes cell death. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. Both cause parts of the brain to stop functioning properly. Signs and symptoms of a stroke may include an inability to move or feel on one side of the body, problems understanding or speaking, dizziness, or loss of vision to one side. Signs and symptoms often appear soon after the stroke has occurred. If symptoms last less than one or two hours, the stroke is a transient ischemic attack (TIA), also called a mini-stroke. A hemorrhagic stroke may also be associated with a severe headache. The symptoms of a stroke can be permanent. Long-term complications may include pneumonia and loss of bladder control. The main risk factor for stroke is high blood pressure. Other risk factors include high blood cholesterol, tobacco smoking, obesity, diabetes mellitus, a previous TIA, end-st ...
