Online Volunteering
Virtual volunteering refers to volunteer activities completed, in whole or in part, using the Internet and a home, school, telecenter, or work computer or other Internet-connected device, such as a smartphone or a tablet. Virtual volunteering is also known as online volunteering, remote volunteering or e-volunteering. Contributing to free and open source software projects or editing Wikipedia are examples of virtual volunteering. In practice In one study, over 70 percent of online volunteers chose assignments requiring one to five hours a week and nearly half chose assignments lasting 12 weeks or less. Some organizations offer online volunteering opportunities which last from ten minutes to an hour. A unique feature of online volunteering is that it can be done from a distance. People with restricted mobility or other special needs participate in ways that might not be possible in traditional face-to-face volunteering. Likewise, online volunteering may allow people to overcome s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volunteering
Volunteering is a voluntary act of an individual or group wikt:gratis, freely giving time and labor for community service. Many volunteers are specifically trained in the areas they work, such as medicine, education, or emergency rescue. Others serve on an as-needed basis, such as in response to a natural disaster. Etymology and history The verb was first recorded in 1755. It was derived from the noun ''volunteer'', in 1600, "one who offers himself for military service," from the Middle French ''voluntaire''. In the non-military sense, the word was first recorded during the 1630s. The word ''volunteering'' has more recent usage—still predominantly military—coinciding with the phrase ''community service''. In a military context, a volunteer military, volunteer army is a military body whose soldiers chose to enter service, as opposed to having been conscripted. Such volunteers do not work "for free" and are given regular pay. 19th century During this time, America expe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Online Tutoring
Online tutoring is the process of tutoring in an online, virtual, or networked, environment, in which teachers and learners participate from separate physical locations. Aside from space, literature also states that participants can be separated by time. Online tutoring is practiced using many different approaches for distinct sets of users. The distinctions are in content and user interface, as well as in tutoring styles and tutor-training methodologies. Definitions associated with online tutoring vary widely, reflecting the ongoing evolution of the technology, the refinement and variation in online learning methodology, and the interactions of the organizations that deliver online tutoring services with the institutions, individuals, and learners that employ the services. This Internet-based service is a form of micropublishing. Concept and definitions An institution, website or individual can offer online tutoring through an internal or external tutoring website or through a l ...

ClickWorkers
ClickWorkers was a small NASA experimental project that uses public volunteers (nicknamed "clickworkers" on the site) for scientific tasks. Clickworkers are able to work when, and for however long they choose, doing routine analysis that would normally require months of work by scientists or graduate students. The web site and database were created and maintained by one engineer, Bob Kanefsky, and advised by two scientists, Nadine Barlow and Virginia Gulick. The pilot study was sponsored by the NASA Ames Director's Discretionary Fund. As of March 31, 2020, the Clickworkers volunteer program appears to be defunct. None of the links to the program are functional, as of that date. Identifying Martian craters The original phase ran from November 2000 to September 2001, identifying and classifying the age of craters on Mars images from Viking Orbiter that had already been analyzed by NASA. The goal was to answer two meta-science questions: # Is the public ready, willing, and able ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Personal Digital Assistant
A personal digital assistant (PDA), also known as a handheld PC, is a variety mobile device which functions as a personal information manager. PDAs have been mostly displaced by the widespread adoption of highly capable smartphones, in particular those based on iOS and Android. A PDA has an electronic visual display. Most models also have audio capabilities, allowing usage as a portable media player, and also enabling many of them to be used as telephones. Nearly all modern PDAs can access the Internet, intranets or extranets via Wi-Fi or Wireless WANs, letting them include a web browser. Sometimes, instead of buttons, PDAs employ touchscreen technology. The first PDA, the Organiser, was released in 1984 by Psion, followed by Psion's Series 3, in 1991. The latter began to resemble the more familiar PDA style, including a full keyboard. The term ''PDA'' was first used on January 7, 1992 by Apple Inc.

Crowdsourcing
Crowdsourcing involves a large group of dispersed participants contributing or producing goods or services—including ideas, votes, micro-tasks, and finances—for payment or as volunteers. Contemporary crowdsourcing often involves digital platforms to attract and divide work between participants to achieve a cumulative result. Crowdsourcing is not limited to online activity, however, and there are various historical examples of crowdsourcing. The word crowdsourcing is a portmanteau of "crowd" and " outsourcing". In contrast to outsourcing, crowdsourcing usually involves less specific and more public groups of participants. Advantages of using crowdsourcing include lowered costs, improved speed, improved quality, increased flexibility, and/or increased scalability of the work, as well as promoting diversity. Crowdsourcing methods include competitions, virtual labor markets, open online collaboration and data donation. Some forms of crowdsourcing, such as in "idea competiti ...

Micro-volunteering
Micro-volunteering describes a volunteer, or team of volunteers, completing small tasks that make up a larger project. These tasks often benefit a research, charitable, or non-governmental organization. It differs from normal volunteerism as the tasks take only minutes to a few hours, and the volunteer does not make a long-term commitment. As a form of virtual volunteering, the tasks are usually distributed and completed online via an internet-connected device, including smartphones. It typically does not require an application process, screening or training period, takes only minutes or a few hours to complete, and does not require an ongoing commitment by the volunteer. History At the global level, in 2000 the United Nations Volunteers programme launched the Online Volunteering service to provide a venue where individuals from across the globe can take action for sustainable human development by supporting the activities of development organizations over the Internet.

Mobile Communication
Mobile telephony is the provision of telephone services to phones which may move around freely rather than stay fixed in one location. Telephony is supposed to specifically point to a voice-only service or connection, though sometimes the line may blur. Mobile phones connect to a terrestrial cellular network of base stations ( cell sites), whereas satellite phones connect to orbiting satellites. Both networks are interconnected to the public switched telephone network (PSTN) to allow any phone in the world to be dialed. In 2010 there were estimated to be five billion mobile cellular subscriptions in the world. History According to internal memos, American Telephone & Telegraph discussed developing a wireless phone in 1915, but were afraid that deployment of the technology could undermine its monopoly on wired service in the U.S. Public mobile phone systems were first introduced in the years after the Second World War and made use of technology developed before and ...

Distributed Computing
A distributed system is a system whose components are located on different computer network, networked computers, which communicate and coordinate their actions by message passing, passing messages to one another from any system. Distributed computing is a field of computer science that studies distributed systems. The components of a distributed system interact with one another in order to achieve a common goal. Three significant challenges of distributed systems are: maintaining concurrency of components, overcoming the clock synchronization, lack of a global clock, and managing the independent failure of components. When a component of one system fails, the entire system does not fail. Examples of distributed systems vary from service-oriented architecture, SOA-based systems to massively multiplayer online games to peer-to-peer, peer-to-peer applications. A computer program that runs within a distributed system is called a distributed program, and ''distributed programming' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tag (metadata)
In information systems, a tag is a keyword or term assigned to a piece of information (such as an Internet bookmark, multimedia, database record, or computer file). This kind of metadata helps describe an item and allows it to be found again by browsing or searching. Tags are generally chosen informally and personally by the item's creator or by its viewer, depending on the system, although they may also be chosen from a controlled vocabulary. Tagging was popularized by websites associated with Web 2.0 and is an important feature of many Web 2.0 services. It is now also part of other database systems, desktop applications, and operating systems. Overview People use tags to aid classification, mark ownership, note boundaries, and indicate online identity. Tags may take the form of words, images, or other identifying marks. An analogous example of tags in the physical world is museum object tagging. People were using textual keywords to classify information and objects long b ...

Pastoral Care
Pastoral care is an ancient model of emotional, social and spiritual support that can be found in all cultures and traditions. The term is considered inclusive of distinctly non-religious forms of support, as well as support for people from religious communities. Definition Modern context Pastoral care as a contemporary term is distinguished from traditional pastoral ministry, which is religious (primarily Christian) and historically tied to Christian beliefs. Institutional pastoral care departments in Europe are increasingly not only multi-faith but inclusive in particular of non-religious, humanist approaches to providing support and comfort. Just as the theory and philosophy behind modern pastoral care is not dependent on any one set of beliefs or traditions, so pastoral care is relating gently and skillfully, with the inner world of individuals from all walks of life, and the elements that go to make up that persons sense of self, their inner resources, resilience and capac ...

Podcast
A podcast is a program made available in digital format for download over the Internet. For example, an episodic series of digital audio or video files that a user can download to a personal device to listen to at a time of their choosing. Streaming applications and podcasting services provide a convenient and integrated way to manage a personal consumption queue across many podcast sources and playback devices. There also exist podcast search engines, which help users find and share podcast episodes. A podcast series usually features one or more recurring hosts engaged in a discussion about a particular topic or current event. Discussion and content within a podcast can range from carefully scripted to completely improvised. Podcasts combine elaborate and artistic sound production with thematic concerns ranging from scientific research to slice-of-life journalism. Many podcast series provide an associated website with links and show notes, guest biographies, transcripts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
