Routinely, mothers are exposing their babies to media crafted specifically for this age group. This study seeks to ascertain the reason. What beliefs do mothers hold regarding the marketing of such media and the expected benefits to their young ones? How does the use of videos such as Baby Einstein benefit the mother? Although mothers reported that video creators want them to think the videos are educational, they are skeptical. However, they continue to let babies watch this "safe" content. Among the 28 mothers interviewed for this project, only four claimed to always watch with their child; the remainder used "video time" to do household chores. Overwhelmingly, mothers heard positive comments about videos from fellow parents, but rarely heard from their pediatricians about possible negative effects on the under-two' s.展开更多

Tepoztlan is a municipality in the northern part of the State of Morelos, located in the South-Central of Mexico. It is a magical town situated on the slopes of the Tepozteco Mountain. It is recognized as one of the most attractive places in the aforementioned state. Its relative proximity to Mexico City makes this town an attractive tourist destination for visitors. The importance of this issue lies mainly in the fact that tourism is one of the largest sources of income and employment generation for the country, so it is essential to strengthen the tourism infrastructure through federal programs of social participation, which promotes the development from the bottom to top. With that objective, the Mexican government created a federal program primarily with the purpose of contributing to the development of rural tourism. So, the "Magic Towns" program emerged as a strategy to generate resources for certain communities and increase the tourist offer. Tepoztlan was one of the first towns to enter the program, so it is relevant to analyze if the benefits generated by this program related to employment are perceived by the population. That is to say, to know the opinion of the settlers on the increase and the conditions of the employment that tourism generates and how the denomination of magical town influences this. Regarding the method used, we can say that it is a research with a quantitative approach, a questionnaire was designed as an instrument for data collection. The sample was obtained by the sampling method called: simple random probabilistic sampling. The results presented here correspond to a sample of 119 inhabitants of Tepoztlan. In summary, the research on this subject allows us to conclude that there is an increase in the generation of jobs in Tepoztl/m since its denomination as Magical Town; however, the working conditions and remuneration generated by tourism are perceived as low and far from the expectations of the population.展开更多
