Text Analysis
Content analysis is the study of documents and communication artifacts, known as texts e.g. photos, speeches or essays. Social scientists use content analysis to examine patterns in communication in a replicable and systematic manner. One of the key advantages of using content analysis to analyse social phenomena is their non-invasive nature, in contrast to simulating social experiences or collecting survey answers. Practices and philosophies of content analysis vary between academic disciplines. They all involve systematic reading or observation of text (literary theory), texts or artifacts which are Coding (social sciences), assigned labels (sometimes called codes) to indicate the presence of interesting, semantics, meaningful pieces of content. By systematically labeling the content of a set of text (literary theory), texts, researchers can analyse patterns of content Quantitative research, quantitatively using Statistics, statistical methods, or use Qualitative research, quali ...

Document
A document is a writing, written, drawing, drawn, presented, or memorialized representation of thought, often the manifestation of nonfiction, non-fictional, as well as fictional, content. The word originates from the Latin ', which denotes a "teaching" or "lesson": the verb ' denotes "to teach". In the past, the word was usually used to denote written proof useful as evidence of a truth or fact. In the computer age, Computer Age, "document" usually denotes a primarily textual computer file, including its structure and format, e.g. fonts, colors, and Computer-generated imagery, images. Contemporarily, "document" is not defined by its transmission medium, e.g., paper, given the existence of electronic documents. "Documentation" is distinct because it has more denotations than "document". Documents are also distinguished from "Realia (library science), realia", which are three-dimensional objects that would otherwise satisfy the definition of "document" because they memorialize ...

Discourse Analysis
Discourse analysis (DA), or discourse studies, is an approach to the analysis of written, spoken, or sign language, including any significant semiotic event. The objects of discourse analysis (discourse, writing, conversation, communicative symbolic interactionism, event) are variously defined in terms of coherent sequences of sentence (linguistics), sentences, propositions, speech acts, speech, or Conversation Analysis#Turn-taking organization, turns-at-talk. Contrary to much of traditional linguistics, discourse analysts not only study language use 'beyond the sentence boundary' but also prefer to analyze 'naturally occurring' language use, not invented examples. Text linguistics is a closely related field. The essential difference between discourse analysis and text linguistics is that discourse analysis aims at revealing social psychology (sociology), socio-psychological characteristics of a person/persons rather than text structure. Discourse analysis has been taken up in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Validity (statistics)
Validity is the main extent to which a concept, conclusion, or measurement is well-founded and likely corresponds accurately to the real world. The word "valid" is derived from the Latin validus, meaning strong. The validity of a measurement tool (for example, a test in education) is the degree to which the tool measures what it claims to measure. Validity is based on the strength of a collection of different types of evidence (e.g. face validity, construct validity, etc.) described in greater detail below. In psychometrics, validity has a particular application known as test validity: "the degree to which evidence and theory support the interpretations of test scores" ("as entailed by proposed uses of tests"). It is generally accepted that the concept of scientific validity addresses the nature of reality in terms of statistical measures and as such is an epistemological and philosophical issue as well as a question of measurement. The use of the term in Validity (logic), logic i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inter-rater Reliability
In statistics, inter-rater reliability (also called by various similar names, such as inter-rater agreement, inter-rater concordance, inter-observer reliability, inter-coder reliability, and so on) is the degree of agreement among independent observers who rate, code, or assess the same phenomenon. Assessment tools that rely on ratings must exhibit good inter-rater reliability, otherwise they are not test validity, valid tests. There are a number of statistics that can be used to determine inter-rater reliability. Different statistics are appropriate for different types of measurement. Some options are joint-probability of agreement, such as Cohen's kappa, Scott's pi and Fleiss' kappa; or inter-rater correlation, concordance correlation coefficient, intra-class correlation, and Krippendorff's alpha. Concept There are several operational definitions of "inter-rater reliability," reflecting different viewpoints about what is a reliable agreement between raters. There are three oper ...

Reliability (statistics)
In statistics and psychometrics, reliability is the overall consistency of a measure. A measure is said to have a high reliability if it produces similar results under consistent conditions:It is the characteristic of a set of test scores that relates to the amount of random error from the measurement process that might be embedded in the scores. Scores that are highly reliable are precise, reproducible, and consistent from one testing occasion to another. That is, if the testing process were repeated with a group of test takers, essentially the same results would be obtained. Various kinds of reliability coefficients, with values ranging between 0.00 (much error) and 1.00 (no error), are usually used to indicate the amount of error in the scores. For example, measurements of people's height and weight are often extremely reliable.The Marketing Accountability Standards Board (MASB) endorses this definition as part of its ongoinCommon Language: Marketing Activities and Metrics Pr ...

Social Constructionism
Social constructionism is a term used in sociology, social ontology, and communication theory. The term can serve somewhat different functions in each field; however, the foundation of this Conceptual framework, theoretical framework suggests various facets of social reality—such as concepts, beliefs, Social norm, norms, and Value (ethics and social sciences), values—are formed through continuous interactions and negotiations among society's members, rather than Empirical research, empirical observation of Reality, physical reality. The theory of social constructionism posits that much of what individuals perceive as 'reality' is actually the outcome of a dynamic process of construction influenced by Convention (norm), social conventions and Social structure, structures. Unlike phenomena that are innately determined or biologically predetermined, these social constructs are collectively formulated, sustained, and shaped by the social environment, social contexts in which t ...

Natural Disaster
A natural disaster is the very harmful impact on a society or community brought by natural phenomenon or Hazard#Natural hazard, hazard. Some examples of natural hazards include avalanches, droughts, earthquakes, floods, heat waves, landslides - including submarine landslides, tropical cyclones, volcanism, volcanic activity and wildfires. Additional natural hazards include blizzards, dust storms, firestorms, hails, ice storms, sinkholes, thunderstorms, tornadoes and tsunamis. A natural disaster can cause list of natural disasters by death toll, loss of life or property damage, damage property. It typically causes economic damage. How bad the damage is depends on how well people are Emergency management, prepared for disasters and how strong the buildings, roads, and other Infrastructure, structures are. Scholars have argued the term "natural disaster" is unsuitable and should be abandoned. Instead, the simpler term ''disaster'' could be used. At the same time, the type of haz ...

Empirical Evidence
Empirical evidence is evidence obtained through sense experience or experimental procedure. It is of central importance to the sciences and plays a role in various other fields, like epistemology and law. There is no general agreement on how the terms ''evidence'' and ''empirical'' are to be defined. Often different fields work with quite different conceptions. In epistemology, evidence is what Justification (epistemology), justifies beliefs or what determines whether holding a certain belief is rational. This is only possible if the evidence is possessed by the person, which has prompted various epistemologists to conceive evidence as private mental states like experiences or other beliefs. In philosophy of science, on the other hand, evidence is understood as that which ''Scientific method#Confirmation, confirms'' or ''disconfirms'' Hypothesis#Scientific hypothesis, scientific hypotheses and arbitrates between competing theories. For this role, evidence must be public and uncont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foucauldian Discourse Analysis
Foucauldian discourse analysis is a form of discourse analysis, focusing on power relationships in society as expressed through language and practices, and based on the theories of Michel Foucault. Overview Subject of analysis Besides focusing on the meaning of a given discourse, the distinguishing characteristic of this approach is its stress on power relationships. These are expressed through language and behaviour, and the relationship between language and power. This form of analysis developed out of Foucault's genealogical work, where power was linked to the formation of discourse within specific historical periods. Some versions of this method stress the genealogical application of discourse analysis to illustrate how discourse is produced to govern social groups. The method analyses how the social world, expressed through language, is affected by various sources of power. As such, this approach is close to social constructivism, as the researcher tries to understand how ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technoculture
Technoculture is a neologism that is not in standard dictionaries but that has some popularity in academia, popularized by editors Constance Penley and Andrew Ross in a book of essays bearing that title. It refers to the interactions between, and politics of, technology and culture. Programs of study "Technoculture" is used by a number of universities to describe subject areas or courses of study. UC Davis, for instance, has a program of technocultural studies. In 2012, the major merged with Film Studies to form Cinema and Techno-Cultural Studies (CaTS), but in 2013 is being reviewed to become Cinema and Technoculture (see below); the University of Western Ontario offers a degree in Media, Information and Technoculture (which they refer to as MIT, offering an "MIT BA"). UC Riverside is in the process of creating a program in technocultural studies beginning with the creation of a graduate certificate program in "Science Fiction and Technoculture Studies."

Privacy
Privacy (, ) is the ability of an individual or group to seclude themselves or information about themselves, and thereby express themselves selectively. The domain of privacy partially overlaps with security, which can include the concepts of appropriate use and Information security, protection of information. Privacy may also take the form of bodily integrity. Throughout history, there have been various conceptions of privacy. Most cultures acknowledge the right of individuals to keep aspects of their personal lives out of the public domain. The right to be free from unauthorized invasions of privacy by governments, corporations, or individuals is enshrined in the privacy laws of many countries and, in some instances, their constitutions. With the rise of technology, the debate regarding privacy has expanded from a bodily sense to include a digital sense. In most countries, the right to digital privacy is considered an extension of the original right to privacy, and many count ...

Inductive Reasoning
Inductive reasoning refers to a variety of method of reasoning, methods of reasoning in which the conclusion of an argument is supported not with deductive certainty, but with some degree of probability. Unlike Deductive reasoning, ''deductive'' reasoning (such as mathematical induction), where the conclusion is ''certain'', given the premises are correct, inductive reasoning produces conclusions that are at best ''probable'', given the evidence provided. Types The types of inductive reasoning include generalization, prediction, statistical syllogism, argument from analogy, and causal inference. There are also differences in how their results are regarded. Inductive generalization A generalization (more accurately, an ''inductive generalization'') proceeds from premises about a Sample (statistics), sample to a conclusion about the statistical population, population. The observation obtained from this sample is projected onto the broader population. : The proportion Q of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
