Evening Trail (6710068953)
Evening is the period of a day that starts at the end of the afternoon and overlaps with the beginning of night. The exact times when evening begins and ends depend on location, time of year, and culture, but it is generally regarded as beginning when the Sun is low in the sky and lasting until the end of twilight. Depending on the speaker, it may start as early as 5 p.m. and to last until night. It may be used colloquially to include the last waning afternoon shortly before sunset. Etymology The word is derived from the Old English ''ǣfnung'', meaning 'the coming of evening, sunset, time around sunset', which originated from ''æfnian'', meaning "become evening, grow toward evening". The Old English ''æfnian'' originated from ''æfen'' (eve), which meant "the time between sunset and darkness", and was synonymous with even (Old English ''æfen''), which meant the end of the day.

Fact-checking
Fact-checking is the process of verifying factual information, in order to promote the veracity and correctness of reporting. Fact-checking can be conducted before (''ante hoc'') or after (''post hoc'') the text is published or otherwise disseminated. Internal fact-checking is such checking done in-house by the publisher; when the text is analyzed by a third party, the process is called external fact-checking. The US remains the largest market for fact-checking. Research suggests that fact-checking does indeed correct perceptions among citizens, as well as discourage politicians from spreading false or misleading claims. However, corrections may decay over time or be overwhelmed by cues from elites that promote less accurate claims. Political fact-checking is sometimes criticized as being opinion journalism. A review of US politics fact-checkers shows a mixed result of whether fact-checking is an effective way to reduce misconceptions, and whether the method is reliable. Histo ...

Source (journalism)
In journalism, a source is a person, publication, or knowledge other record or document that gives timely information. Outside journalism, sources are sometimes known as "news sources". Examples of sources include but are not limited to official records, publications or broadcasts, officials in government or business, organizations or corporations, witnesses of crime, accidents or other events, and people involved with or affected by a news event or issue. According to Shoemaker (1996) and McQuail (1994), there are a multitude of factors that tend to condition the acceptance of sources as bona fide by investigative journalists. Reporters are expected to develop and cultivate sources, especially if they regularly cover a specific topic, known as a "beat". Beat reporters must, however, be cautious of becoming too close to their sources. Reporters often, but not always, give greater leeway to sources with little experience. For example, sometimes a person will say they don't want ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
