Category: Anxiety

Test anxiety is a combination of physiological over-arousal, tension and somatic symptoms, along with worry, dread, fear of failure, and catastrophizing, that occur before or during test situations. It is a physiological condition in which people experience extreme stress, anxiety, and discomfort during and/or before taking a test. This anxiety creates significant barriers to learning and performance. Research suggests that high levels of emotional distress have a direct correlation to reduced academic performance and higher overall student drop-out rates. Test anxiety can have broader consequences, negatively affecting a student’s social, emotional and behavioural development, as well as their feelings about themselves and school. Highly test-anxious students score about 12 percentile points below their low anxiety peers. Test anxiety is prevalent amongst the student populations of the world. It has been studied formally since the early 1950s beginning with researchers George Mandler and Seymour Sarason. Sarason’s brother, Irwin G. Sarason, then contributed to early investigation of test anxiety, clarifying the relationship between the focused effects of test anxiety, other focused forms of anxiety, and generalized anxiety. Test anxiety can also be labeled as anticipatory anxiety, situational anxiety or evaluation anxiety. Some anxiety is normal and often helpful to stay mentally and physically alert. When one experiences too much anxiety, however, it can result in emotional or physical distress, difficulty concentrating, and emotional worry. Inferior performance arises not because of intellectual problems or poor academic preparation, but because testing situations create a sense of threat for those experiencing test anxiety; anxiety resulting from the sense of threat then disrupts attention and memory function. Researchers suggest that between 25 and 40 percent of students experience test anxiety. Students with disabilities and students in gifted educations classes tend to experience high rates of test anxiety. Students who experience test anxiety tend to be easily distracted during a test, experience difficulty with comprehending relatively simple instructions, and have trouble organizing or recalling relevant information.

Meditations (Medieval Greek: Τὰ εἰς ἑαυτόν, translit. Ta eis heauton, literally “things to one’s self”) is a series of personal writings by Marcus Aurelius, Roman Emperor from 161 to 180 AD, recording his private notes to himself and ideas on Stoic philosophy. Marcus Aurelius wrote the 12 books of the Meditations in Koine Greek as a source for his own guidance and self-improvement. It is possible that large portions of the work were written at Sirmium, where he spent much time planning military campaigns from 170 to 180. Some of it was written while he was positioned at Aquincum on campaign in Pannonia, because internal notes tell us that the first book was written when he was campaigning against the Quadi on the river Granova (modern-day Hron) and the second book was written at Carnuntum. It is unlikely that Marcus Aurelius ever intended the writings to be published and the work has no official title, so “Meditations” is one of several titles commonly assigned to the collection. These writings take the form of quotations varying in length from one sentence to long paragraphs.

The relationship between the stress and strain that a particular material displays is known as that particular material’s stress–strain curve. It is unique for each material and is found by recording the amount of deformation (strain) at distinct intervals of tensile or compressive loading (stress). These curves reveal many of the properties of a material (including data to establish the Modulus of Elasticity, E). Stress–strain curves of various materials vary widely, and different tensile tests conducted on the same material yield different results, depending upon the temperature of the specimen and the speed of the loading. It is possible, however, to distinguish some common characteristics among the stress–strain curves of various groups of materials and, on this basis, to divide materials into two broad categories; namely, the ductile materials and the brittle materials. Consider a bar of cross sectional area A being subjected to equal and opposite forces F pulling at the ends so the bar is under tension. The material is experiencing a stress defined to be the ratio of the force to the cross sectional area of the bar: s t r e s s = F A {displaystyle mathrm {stress} ={tfrac {F}{A}}} Note that for engineering purposes, we often assume the cross-section area of the material does not change during the whole deformation process, which is not true since the actual area will decrease while deforming due to elastic and plastic deformation. The one assuming cross-section area fixed is so called “engineering stress-strain curve”, the latter is “true stress-strain curve”. In a tension test, true strain is less than engineering strain. Thus, a point defining true stress-strain curve is displaced upwards and to the left to define the equivalent engineering stress-strain curve. The difference between the true and engineering stresses and strains will increase with plastic deformation. At low strains (such as elastic deformation), the differences between the two is negligible. Two important effects necessary to understand the true stress are the effects of strain rate susceptibility and strain rate hardening upon the true stress. Time is often neglected in the initial stress-strain curve relations, but at higher strain rates, higher stresses will occur according to the relationship σT=k’ἕTm where m is the strain rate susceptibility. To account for the resistance to necking, the relationship σT=kεTn must also be considered, where n is the strain hardening coefficient and is typically between 0.02 and 0.50, depending upon the material. By combining these two relationships, a relationship of σT=kεTnἕTm can be found. However, as real stresses and strains do not occur uniaxially, considerations for multiaxial stresses must be added to this relationship to model real stresses. This stress is called the tensile stress because every part of the object is subjected to tension. The SI unit of stress is the newton per square meter, which is called the pascal. 1 pascal = 1 Pa = 1 N/m2 Now consider a force that is applied tangentially to an object. The ratio of the shearing force to the area A is called the shear stress. If the object is twisted through an angle q, then the shear strain is: s t r a i n = tan ⁡ q {displaystyle mathrm {strain} =tan {q}} Finally, the shear modulus MS of a material is defined as the ratio of shear stress to shear strain at any point in an object made of that material. The shear modulus is also known as the torsion modulus.

Death anxiety is anxiety caused by thoughts of death. One source defines death anxiety as a “feeling of dread, apprehension or solicitude (anxiety) when one thinks of the process of dying, or ceasing to ‘be'”. Also referred to as thanatophobia (fear of death), death anxiety is distinguished from necrophobia, which is a specific fear of dead or dying people and/or things (i.e., fear of others who are dead or dying, not of one’s own death or dying). Additionally, there is anxiety caused by death-related thought-content, which might be classified within a clinical setting by a psychiatrist as morbid and/or abnormal, which for classification pre-necessitates a degree of anxiety which is persistent and interferes with everyday functioning. Lower ego integrity, more physical problems and more psychological problems are predictive of higher levels of death anxiety in elderly people perceiving themselves close to death. Death anxiety can cause extreme timidness with a person’s attitude towards discussing organ donation and anything to do with death.

A picnic is a meal taken outdoors (al fresco) as part of an excursion – ideally in scenic surroundings, such as a park, lakeside, or other place affording an interesting view, or else in conjunction with a public event such as preceding an open-air theatre performance, and usually in summer. Picnics are usually meant for the late mornings or midday breakfasts, but could also be held as a luncheonette or a dinner event. Descriptions of picnics show that the idea of a meal that was jointly contributed and was enjoyed out-of-doors was essential to a picnic from the early 19th century. Picnics are often family-oriented but can also be an intimate occasion between two people or a large get together such as company picnics and church picnics. It is also sometimes combined with a cookout, usually a form of barbecue; either grilling (griddling, gridironing, or charbroiling), braising (by combining a charbroil or gridiron grill with a broth-filled pot), baking, or a combination of all of the above. On romantic and family picnics, a picnic basket and a blanket (to sit or recline on) are usually brought along. Outdoor games or some other form of entertainment are common at large picnics. In established public parks, a picnic area generally includes picnic tables and possibly other items related to eating outdoors, such as built-in grills, water faucets, garbage containers, and restrooms. Some picnics are a potluck, an entertainment at which each person contributed some dish to a common table for all to share. When the picnic is not also a cookout, the food eaten is rarely hot, instead taking the form of deli sandwiches, finger food, fresh fruit, salad, cold meats and accompanied by chilled wine or champagne or soft drinks.

Fremont Peak is a summit in the Gabilan Range, one of the mountain ranges paralleling California’s central coast. The peak affords clear views of the Salinas Valley, Monterey Bay, the southern part of the Santa Clara Valley, and surrounding mountain ranges. It is located on Rocky Ridge, 11 miles (18 km) northeast of Salinas, California. The peak is the site of Fremont Peak State Park which was established with 188 acres (76 ha) in 1936. Today the park has camping and picnic facilities, and is favored by astronomers for its clear views unsullied by artificial light. The Fremont Peak Observatory Association maintains a 30-inch (760 mm) diameter f/4.8 Newtonian “Challenger” telescope which was built by telescope maker Kevin Medlock in the early 1980s. The peak is also the site of the transmitters for television stations such as KSBW and KCBA and for radio stations such as KDON-FM.

A campsite or camping pitch is a place used for overnight stay in an outdoor area. In UK English, a campsite is an area, usually divided into a number of pitches, where people can camp overnight using tents or camper vans or caravans; this UK English use of the word is synonymous with the US English expression campground. In American English, the term campsite generally means an area where an individual, family, group, or military unit can pitch a tent or park a camper; a campground may contain many campsites. There are two types of campsites: an impromptu area (as one might decide to stop while backpacking or hiking) a designated area with improvements and various facilities (see below).
