Connor-Davidson Resilience Scale
The Connor-Davidson Resilience Scale (CD-RISC) was developed by Kathryn M. Connor and Jonathan R.T. Davidson as a means of assessing resilience. The CD-RISC is based on Connor and Davidson's operational definition of resilience, which is the ability to "thrive in the face of adversity." Since its development in 2003, the CD-RISC has been tested in a several contexts with a variety of populations (see Generalizability) and has been modified into different versions (see Forms).

Universal Medicine
Universal Medicine (UniMed) (UM) is a socially harmful cult founded and led by Serge Benhayon, a former bankrupt tennis coach from New South Wales (NSW) Australia who has no medical qualifications. It sells "Esoteric healing" products, music, publications, workshops and courses. None of the healing modalities are evidence based or have been proven effective by scientific research. Uruguayan-born Benhayon founded the group in 1999 after receiving what he described as an "energetic impress" while on the toilet. A NSW Supreme Court jury found it was true to say that he leads a "socially dangerous" and "socially harmful cult", "intentionally indecently touched" clients and "is a charlatan who makes fraudulent medical claims". In a British court ruling, UM was found to be "a cult with some potentially harmful and sinister elements". The organisation and unregulated health service provider is principally located in Goonellabah and Wollongbar, near Lismore, NSW, Australia. Its European headquarters are known as "The Lighthouse" and is situated between Tytherington and Frome, Somerset, England. The signature treatments practised and taught by Universal Medicine are "esoteric breast massage", "esoteric healing", "ovarian readings", "chakra-puncture", "esoteric connective tissue therapy" and "esoteric ovary massage". All treatments were devised by non-registered health practitioner Serge Benhayon, who has claimed the business grosses at least AUD$2 million a year from courses and retreats. The followers of its doctrine "The Way of the Livingness" are known collectively as "The Student Body". "The Teachings" are classified into meditation, self-care, nutrition, exercise, music, reincarnation, psychological wellbeing and the esoteric, and are supported by audio, books, and online lectures. Serge Benhayon describes himself as a "seer", calls himself the "Ascended Master", and followers call him the "new Messiah". They also believe he "was the one sent from (the mythical kingdom of) Shambhala to awaken us all", is the only human to have achieved the "highest level of initiation" on earth and claim the NSW Supreme Court ruling against him is "totally untrue". In the British court ruling, the doctrine was said to be one of "erroneous and malign beliefs". While Benhayon has denied engaging in unethical practices, significant evidence to the contrary has been documented.

Forensic Toxicology
Forensic toxicology is the use of toxicology and disciplines such as analytical chemistry, pharmacology and clinical chemistry to aid medical or legal investigation of death, poisoning, and drug use. The primary concern for forensic toxicology is not the legal outcome of the toxicological investigation or the technology utilized, but rather the obtainment and interpretation of results. A toxicological analysis can be done to various kinds of samples. A forensic toxicologist must consider the context of an investigation, in particular any physical symptoms recorded, and any evidence collected at a crime scene that may narrow the search, such as pill bottles, powders, trace residue, and any available chemicals. Provided with this information and samples with which to work, the forensic toxicologist must determine which toxic substances are present, in what concentrations, and the probable effect of those chemicals on the person. In the United States, forensic toxicology can be separated into 3 disciplines: Postmortem toxicology, human performance toxicology, and forensic drug testing (FDT). Postmortem toxicology includes the analysis of biological specimens taken from an autopsy to identify the effect of drugs, alcohol, and poisons. A wide range of biological specimens may be analyzed including blood, urine, gastric contents, oral fluids, hair, tissues, and more. The forensic toxicologist works with pathologists, medical examiners, and coroners to help determine the cause and manner of death. In human performance toxicology, a dose-response relationship between a drug(s) present in the body and the effects on the body are examined. This field of forensic toxicology is responsible for building and implementing laws such as driving under the influence of alcohol or drugs. Lastly, forensic drug testing (FDT) is the detection of drug use among individuals in the workplace, sport doping, drug-related probation, and new job applicant screenings. Determining the substance ingested is often complicated by the body's natural processes (see ADME), as it is rare for a chemical to remain in its original form once in the body. For example: heroin is almost immediately metabolised into another substance and further to morphine, making detailed investigation into factors such as injection marks and chemical purity necessary to confirm diagnosis. The substance may also have been diluted by its dispersal through the body; while a pill or other regulated dose of a drug may have grams or milligrams of the active constituent, an individual sample under investigation may only contain micrograms or nanograms.

Field
In physics, a field is a physical quantity, represented by a scalar, vector, or tensor, that has a value for each point in space and time. For example, on a weather map, the surface temperature is described by assigning a number to each point on the map; the temperature can be considered at a certain point in time or over some interval of time, to study the dynamics of temperature change. A surface wind map, assigning an arrow to each point on a map that describes the wind speed and direction at that point, is an example of a vector field, i.e. a 1-dimensional (rank-1) tensor field. Field theories, mathematical descriptions of how field values change in space and time, are ubiquitous in physics. For instance, the electric field is another rank-1 tensor field, while electrodynamics can be formulated in terms of two interacting vector fields at each point in spacetime, or as a single-rank 2-tensor field. In the modern framework of the quantum theory of fields, even without referring to a test particle, a field occupies space, contains energy, and its presence precludes a classical "true vacuum". This has led physicists to consider electromagnetic fields to be a physical entity, making the field concept a supporting paradigm of the edifice of modern physics. "The fact that the electromagnetic field can possess momentum and energy makes it very real ... a particle makes a field, and a field acts on another particle, and the field has such familiar properties as energy content and momentum, just as particles can have." In practice, the strength of most fields diminishes with distance, eventually becoming undetectable. For instance the strength of many relevant classical fields, such as the gravitational field in Newton's theory of gravity or the electrostatic field in classical electromagnetism, is inversely proportional to the square of the distance from the source (i.e., they follow Gauss's law). A field can be classified as a scalar field, a vector field, a spinor field or a tensor field according to whether the represented physical quantity is a scalar, a vector, a spinor, or a tensor, respectively. A field has a consistent tensorial character wherever it is defined: i.e. a field cannot be a scalar field somewhere and a vector field somewhere else. For example, the Newtonian gravitational field is a vector field: specifying its value at a point in spacetime requires three numbers, the components of the gravitational field vector at that point. Moreover, within each category (scalar, vector, tensor), a field can be either a classical field or a quantum field, depending on whether it is characterized by numbers or quantum operators respectively. In this theory an equivalent representation of field is a field particle, for instance a boson.

Socialist Party of America
The Socialist Party of America (SPA) was a multi-tendency democratic socialist and social democratic political party in the United States formed in 1901 by a merger between the three-year-old Social Democratic Party of America and disaffected elements of the Socialist Labor Party of America which had split from the main organization in 1899. In the first decades of the 20th century, it drew significant support from many different groups, including trade unionists, progressive social reformers, populist farmers and immigrants. However, it refused to form coalitions with other parties, or even to allow its members to vote for other parties. Eugene V. Debs twice won over 900,000 votes in presidential elections (1912 and 1920) while the party also elected two Representatives (Victor L. Berger and Meyer London), dozens of state legislators, more than a hundred mayors and countless lesser officials. The party's staunch opposition to American involvement in World War I, although welcomed by many, also led to prominent defections, official repression and vigilante persecution. The organization was further shattered by a factional war over how to respond to the October Revolution in Imperial Russia in 1917 and the establishment of the Communist International in 1919—many members left the party in favor of the Communist Party USA. After endorsing Robert M. La Follette's presidential campaign in 1924, the party returned to independent action at the presidential level. It had modest growth in the early 1930s behind presidential candidate Norman Thomas. The party's appeal was weakened by the popularity of President Franklin D. Roosevelt's New Deal, the organization and flexibility of the Communist Party under Earl Browder and the resurgent labor movement's desire to support sympathetic Democratic Party politicians. A divisive and ultimately unsuccessful attempt to broaden the party by admitting followers of Leon Trotsky and Jay Lovestone caused the traditional "Old Guard" to leave and form the Social Democratic Federation. While the party was always strongly anti-fascist as well as anti-Stalinist, its opposition to American entry in World War II cost it both internal and external support. The party stopped running presidential candidates after 1956, when its nominee Darlington Hoopes won fewer than 6,000 votes. In the party's last decades, its members, many of them prominent in the labor, peace, civil rights and civil liberties movements, fundamentally disagreed about the socialist movement's relationship to the labor movement and the Democratic Party and about how best to advance democracy abroad. In 1970–1973, these strategic differences had become so acute that the Socialist Party of America changed its name to Social Democrats, USA. Leaders of two of its caucuses formed separate socialist organizations, the Democratic Socialist Organizing Committee and the Socialist Party USA, the former of which became a precursor to the largest socialist organization in the United States in 2017, the Democratic Socialists of America.

Adverse Possession
Adverse possession, sometimes colloquially described as "squatter's rights",[lower-alpha 1] is a legal principle that applies when a person who does not have legal title to a piece of property—usually land (real property)—attempts to claim legal ownership based upon a history of possession or occupation of the land without the permission of its legal owner. In general, a property owner has the right to recover possession of their property from unauthorized possessors through legal action such as ejectment. However, in the English common law tradition, courts have long ruled that when someone occupies a piece of property without permission and the property's owner does not exercise their right to recover their property for a significant period of time, not only is the original owner prevented from exercising their right to exclude, but an entirely new title to the property springs up in the adverse possessor. In effect, the adverse possessor becomes the property's new owner.[lower-alpha 2] Over time, legislatures have created statutes of limitations that specify the length of time that owners have to recover possession of their property from adverse possessors. In the United States, for example, these time limits vary widely between individual states, ranging from as low as five years to as many as 40 years. Although the elements of an adverse possession action are different in every jurisdiction, a person claiming adverse possession is usually required to prove non-permissive use of the property that is actual, open and notorious, exclusive, adverse, and continuous for the statutory period.[lower-alpha 3] Personal property, traditionally known as "chattel", may also be adversely possessed, but owing to the differences in the nature of real and chattel property, the rules governing such claims are rather more stringent, and favor the legal owner rather than the adverse possessor. Claims for adverse possession of chattel often involve works of art.

Constitutive Role of Communication in Organizations
The focal point of the communicative constitution of organizations is that “organization is an effect of communication not its predecessor”. This approach, also referred to as the CCO perspective, posits that "elements of communication, rather than being fixed in advance, are reflexively constituted within the act of communication itself".

Thin Filament Structure and Assembly
The actin containing tropomyosin and troponin decorated thin filaments form one of the crucial components of the contractile apparatus in muscles. The thin filaments are organized into densely packed lattices interdigitated with myosin-based thick filaments. The crossbridge interactions between these myofilaments drive muscle contraction, and the degree of myofilament overlap is a key factor of contractile force determination.

GIS Applications
A Geographic Information System (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data. GIS applications are tools that allow users to create interactive queries (user-created searches), analyze spatial information, edit data in maps, and present the results of all these operations. GIS (more commonly GIScience) sometimes refers to geographic information science (GIScience), the science underlying geographic concepts, applications, and systems. Since the mid-1980s, geographic information systems have become valuable tool used to support a variety of city and regional planning functions. GIS can refer to a number of different technologies, processes, techniques and methods. It is attached to many operations and has many applications related to engineering, planning, management, transport/logistics, insurance, telecommunications, and business. For that reason, GIS and location intelligence applications can be the foundation for many location-enabled services that rely on analysis and visualization. GIS can relate unrelated information by using location as the key index variable. Locations or extents in the Earth space–time may be recorded as dates/times of occurrence, and x, y, and z coordinates representing, longitude, latitude, and elevation, respectively. All Earth-based spatial–temporal location and extent references should be relatable to one another and ultimately to a "real" physical location or extent. This key characteristic of GIS has begun to open new avenues of scientific inquiry.

Classifications of Routing Protocols in Ad hoc Networks
Wireless Mobile Ad-hoc Networks (WANETs-MANETs) are one of the most in-demand networks in our day and age, being widely used in military fields, disaster environments, autonomous robots, vehicular networks, rural and urban environments, and UAV applications. This is due to the remarkable features of versatility, robustness, and self-configuration with no infrastructure. Such networks' main objective is to deliver reliable data transmission directly to nodes such routers, access points, smartphones, and vehicles with dynamically adjusting the data routes in accordance with the network conditions and GPS information. However, mobility in ad hoc networks is yet the crucial issue due to the dynamic changes of the network topology; this makes data routing a substantial challenge. To this end, choosing or design the proper routing protocol plays important role in establishing robust, secure and efficient data communication for randomly distributed and unrestricted movement of nodes.
