Telecommunications Data Retention
Data retention defines the policies of persistent data and records management for meeting legal and business data archival requirements. Although sometimes interchangeable, it is not to be confused with the Data Protection Act 1998. The different data retention policies weigh legal and privacy concerns against economics and need-to-know concerns to determine the retention time, archival rules, data formats, and the permissible means of storage, access, and encryption. In the field of telecommunications, data retention generally refers to the storage of call detail records (CDRs) of telephony and internet traffic and transaction data ( IPDRs) by governments and commercial organisations. In the case of government data retention, the data that is stored is usually of telephone calls made and received, emails sent and received, and websites visited. Location data is also collected. The primary objective in government data retention is traffic analysis and mass surveillance. By ana ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grade Retention
Grade retention or grade repetition is the process of a student repeating a grade due to failing on the previous year. An alternative to grade retention due to failure is a policy of social promotion, with the idea that staying within their same age group is important. Social promotion is the obligatory advancement of all students regardless of achievements and absences. Social promotion is used more in countries which use tracking to group students according to academic ability. Some academic scholars believe that underperformance must be addressed with intensive remedial help, such as summer school or after-school programs in contrast to failing and retaining the student. In most countries, retention rates are currently decreasing. In the United States, grade retention can be used in kindergarten through to twelfth grade; however, students in grades seven through twelve are usually only retained in the specific failed subject due to each subject having its own specific class ...

Urinary Retention
Urinary retention is an inability to completely empty the bladder. Onset can be sudden or gradual. When of sudden onset, symptoms include an inability to urinate and lower abdominal pain. When of gradual onset, symptoms may include loss of bladder control, mild lower abdominal pain, and a weak urine stream. Those with long-term problems are at risk of urinary tract infections. Causes include blockage of the urethra, nerve problems, certain medications, and weak bladder muscles. Blockage can be caused by benign prostatic hyperplasia (BPH), urethral strictures, bladder stones, a cystocele, constipation, or tumors. Nerve problems can occur from diabetes, trauma, spinal cord problems, stroke, or heavy metal poisoning. Medications that can cause problems include anticholinergics, antihistamines, tricyclic antidepressants, cyclobenzaprine, diazepam, nonsteroidal anti-inflammatory drugs (NSAID), amphetamines, and opioids. Diagnosis is typically based on measuring the amount ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Employee Retention
Employee retention is the ability of an organization to retain its employees and make sure the sustainability of employees. Employee retention can be represented by a simple statistic (for example, a retention rate of 80% usually indicates that an organization kept 80% of its employees in a given period). Employee retention is also the strategies employers use to try to retain the employees in their workforce. A distinction should be drawn between low-performing employees and top performers, and efforts to retain employees should be targeted at valuable, contributing employees. Employee turnover is a sign of deeper issues that have not been resolved, which may include low employee morale, absence of a clear career path, lack of recognition, poor employee-manager relationships or many other issues. A lack of job satisfaction and commitment to the organization can also cause an employee to withdraw and begin looking for other opportunities. Pay sometimes plays a smaller role in ind ...

Variable Retention
Variable retention is a relatively new silvicultural system that retains forest structural elements for at least one rotation in order to preserve environmental values associated with structurally complex forests. Some examples for environmental values are forest cover connectivity, soil stabilization, microclimate under retained trees, habitats associated with live or dead trees and species diversity due to habitat preservation, and wildlife corridor preservation. Variable retention also aids in emulation of natural disturbances by leaving behind some residual structure from previous stand which is typical for stand replacing disturbances Traditional silviculture systems such as clearcut, patch cut, shelterwood, etc. are focused on maximizing timber production and future regeneration of the trees. Variable retention on the other hand is focused on what is retained Value of variable retention Variable retention is gradually becoming a popularly promoted tool for helping resolve ...

Customer Retention
Customer retention refers to the ability of a company or product to retain its customers over some specified period. High customer retention means customers of the product or business tend to return to, continue to buy or in some other way not defect to another product or business, or to non-use entirely. Selling organizations generally attempt to reduce customer defections. Customer retention starts with the first contact an organization has with a customer and continues throughout the entire lifetime of a relationship and successful retention efforts take this entire lifecycle into account. A company's ability to attract and retain new customers is related not only to its product or services, but also to the way it services its existing customers, the value the customers actually perceive as a result of utilizing the solutions, and the reputation it creates within and across the marketplace. Successful customer retention involves more than giving the customer what they expect. G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Memory And Retention In Learning
Human memory is the process in which information and material is encoded, stored and retrieved in the brain. Memory is a property of the central nervous system, with three different classifications: short-term, long-term and sensory memory. The three types of memory have specific, different functions but each are equally important for memory processes. Sensory information is transformed and encoded in a certain way in the brain, which forms a memory representation. This unique coding of information creates a memory. Memory and retention are linked because any retained information is kept in human memory stores, therefore without human memory processes, retention of material would not be possible. In addition, memory and the process of learning are also closely connected. Memory is a site of storage and enables the retrieval and encoding of information, which is essential for the process of learning. Learning is dependent on memory processes because previously stored knowledge fun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retention Rate
The term "retention rate" is used in a variety of fields, including marketing, investing, education, in the workplace and in clinical trials. Maintaining retention in each of these fields often results in a positive outcome for the overall organization or school, or pharmacological study. In marketing, retention rate is used to count customers and track customer activity irrespective of the number of transactions (or dollar value of those transactions) made by each customer. "''Retention rate is the ratio of the number of retained customers to the number at risk".'' In contractual situations, it makes sense to talk about the number of customers currently under contract and the percentage retained when the contract period runs out." This term should not be confused with growth (decline) in customer counts. Retention refers only to existing customers in contractual situations. "In non-contractual situations (such as catalog sales), it makes less sense to talk about the ''current'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retention Election
A judicial retention election (or retention referendum) is a periodic process in some jurisdictions whereby a judge is subject to a referendum held at the same time as a general election. The judge is removed from office if a majority of votes are cast against retention. A judicial retention vote differs from a regular election in that voters are not asked to choose from a list of candidates — the judges on the ballot do not have opponents. Rather, the voter chooses between electing the incumbent judge to a further term in office (i.e. voting in favor of "retention") or voting against. In addition, the judge's party affiliation is typically not listed on the ballot. A judge is deemed to have been retained if ballots cast in favor of retention outnumber those against. By way of example, judicial retention elections are used in the U.S. state of Illinois. In the 2008 general election, the voters of Cook County, Illinois were asked to vote on the following: Additional instruc ...

Water Retention (medicine)
Edema, also spelled oedema, and also known as fluid retention, dropsy, hydropsy and swelling, is the build-up of fluid in the body's tissue. Most commonly, the legs or arms are affected. Symptoms may include skin which feels tight, the area may feel heavy, and joint stiffness. Other symptoms depend on the underlying cause. Causes may include venous insufficiency, heart failure, kidney problems, low protein levels, liver problems, deep vein thrombosis, infections, angioedema, certain medications, and lymphedema. It may also occur after prolonged sitting or standing and during menstruation or pregnancy. The condition is more concerning if it starts suddenly, or pain or shortness of breath is present. Treatment depends on the underlying cause. If the underlying mechanism involves sodium retention, decreased salt intake and a diuretic may be used. Elevating the legs and support stockings may be useful for edema of the legs. Older people are more commonly affected. The wo ...

News Server Operation
A news server is a collection of software used to handle Usenet articles. It may also refer to a computer itself which is primarily or solely used for handling Usenet. Access to Usenet is only available through news server providers. Articles and posts End users often use the term "posting" to refer to a single message or file posted to Usenet. For articles containing plain text, this is synonymous with an article. For binary content such as pictures and files, it is often necessary to split the content among multiple articles. Typically through the use of numbered Subject: headers, the multiple-article postings are automatically reassembled into a single unit by the newsreader. Most servers do not distinguish between single and multiple-part postings, dealing only at the level of the individual component articles. Headers and overviews Each news article contains a complete set of header lines, but in common use the term "headers" is also used when referring to the News Overv ...
