audience. Limitations in current research methodologies While the above examples show how the different languages are used on signs within Singapore, there is scant data on the motivations behind these variations seen, as exemplified by the advisory for "No Alcohol" sales in Little India, which showcased a rare variation from the usage of the four main languages that are commonly seen on most advisory signs. Similarly, the Ministry of Health, in a response to a feedback requesting all hospitals to have four languages on its entrances, has claimed that usage of pictorial signages was better in conveying messages, as opposed to using all four languages. Due to problems in the research methodology and lack of governmental statutes that explain these variations, the study on the linguistics landscape in Singapore remain as a controversial field. These problems include non-linearity, where the large numbers of variations seen in Singapore prevents the application of any trends to understand the landscape; and also the lack of any standard legislation that determines any fixed rules on usage of languages on signs. Controversies In a 2012 pilot program, SMRT trains began announcements of station names in both English and Mandarin Chinese so as to help Mandarin Chinese-speaking senior citizens cope better with the sudden increase in new stations. However, this received mixed reactions from the public. Some people pointed out that there were senior citizens who did not speak Mandarin, while others complained of feeling alienated. In reaction to this, SMRT claimed that the announcements were only recorded in English and Mandarin because the Malay and Tamil names of stations sounded very similar to the English names. In 2013, a group of Tamil speakers petitioned the Civil Aviation Authority of Singapore to include Tamil instead of Japanese on all the signs in the Singapore Changi Airport. Even though only 5% of the Singapore population speaks Tamil, they argued that since Tamil is one of the four official languages of Singapore, it should be used to reflect Singapore's multi-racial background. In 2014, there were reports of erroneous translations on road signs of popular tourist attractions such as Lau Pa Sat and Gardens by the Bay made by the Singapore Tourism Board, mostly involving English to Tamil translations. According to The Straits Times, rectifications are underway to ensure that the translations are now correct. Media and the arts The free-to-air channels in Singapore are run by Mediacorp and
