Geodetic coordinatesGeodetic coordinates are a type of curvilinear orthogonal coordinate system used in geodesy based on a reference ellipsoid. They include geodetic latitude (north/south) φ, longitude (east/west) λ, and ellipsoidal height h (also known as geodetic height). The triad is also known as Earth ellipsoidal coordinates (not to be confused with ellipsoidal-harmonic coordinates). Longitude measures the rotational angle between the zero meridian and the measured point. By convention for the Earth, Moon and Sun, it is expressed in degrees ranging from −180° to +180°.
Spatial reference systemA spatial reference system (SRS) or coordinate reference system (CRS) is a framework used to precisely measure locations on the surface of Earth as coordinates. It is thus the application of the abstract mathematics of coordinate systems and analytic geometry to geographic space. A particular SRS specification (for example, "Universal Transverse Mercator WGS 84 Zone 16N") comprises a choice of Earth ellipsoid, horizontal datum, map projection (except in the geographic coordinate system), origin point, and unit of measure.
Preventable causes of deathPreventable causes of death are causes of death related to risk factors which could have been avoided. The World Health Organization has traditionally classified death according to the primary type of disease or injury. However, causes of death may also be classified in terms of preventable risk factors—such as smoking, unhealthy diet, sexual behavior, and reckless driving—which contribute to a number of different diseases. Such risk factors are usually not recorded directly on death certificates, although they are acknowledged in medical reports.
Childhood obesityChildhood obesity is a condition where excess body fat negatively affects a child's health or well-being. As methods to determine body fat directly are difficult, the diagnosis of obesity is often based on BMI. Due to the rising prevalence of obesity in children and its many adverse health effects it is being recognized as a serious public health concern. The term 'overweight' rather than 'obese' is often used when discussing childhood obesity, as it is less stigmatizing, although the term 'overweight' can also refer to a different BMI category.
Participation biasParticipation bias or non-response bias is a phenomenon in which the results of elections, studies, polls, etc. become non-representative because the participants disproportionately possess certain traits which affect the outcome. These traits mean the sample is systematically different from the target population, potentially resulting in biased estimates. For instance, a study found that those who refused to answer a survey on AIDS tended to be "older, attend church more often, are less likely to believe in the confidentiality of surveys, and have lower sexual self disclosure.
Sion, SwitzerlandSion (sjɔ̃; Sitten ˈzɪtn̩; Seduno; Sedunum) is a Swiss town, a municipality, and the capital of the canton of Valais and of the district of Sion. it had a population of (known as Sédunois(es)). On 17 January 1968, the former municipality of Bramois merged into the municipality of Sion. On 1 January 2013, the former municipality of Salins merged into the municipality of Sion, and on 1 January 2017, Les Agettes did the same. Landmarks in Sion include the Basilique de Valère and the Château de Tourbillon.
Biel/BienneBiel/Bienne (official bilingual wording; biːl, bjɛn) is a town and a municipality in the Biel/Bienne administrative district in the canton of Bern in Switzerland. Biel/Bienne lies on the language boundary between the French-speaking and German-speaking parts of Switzerland, and is bilingual throughout. Biel is the German name for the town; Bienne its French counterpart. The town is often referred to in both languages simultaneously. Since 1 January 2005, the official name has been "Biel/Bienne".
AarauAarau (ˈaːraʊ, ˈɑːræu̯) is a town, a municipality, and the capital of the northern Swiss canton of Aargau. The town is also the capital of the district of Aarau. It is German-speaking and predominantly Protestant. Aarau is situated on the Swiss plateau, in the valley of the Aare, on the river's right bank, and at the southern foot of the Jura Mountains, and is west of Zürich, south of Basel and northeast of Bern. The municipality borders directly on the canton of Solothurn to the west. It is the largest town in Aargau.
Local tangent plane coordinatesLocal tangent plane coordinates (LTP), also known as local ellipsoidal system, local geodetic coordinate system, or local vertical, local horizontal coordinates (LVLH), are a spatial reference system based on the tangent plane defined by the local vertical direction and the Earth's axis of rotation. It consists of three coordinates: one represents the position along the northern axis, one along the local eastern axis, and one represents the vertical position.
EthnocentrismEthnocentrism in social science and anthropology—as well as in colloquial English discourse—means to apply one's own culture or ethnicity as a frame of reference to judge other cultures, practices, behaviors, beliefs, and people, instead of using the standards of the particular culture involved. Since this judgment is often negative, some people also use the term to refer to the belief that one's culture is superior to, or more correct or normal than, all others—especially regarding the distinctions that define each ethnicity's cultural identity, such as language, behavior, customs, and religion.
