Perceived health problems in swimmers according to the chemical treatment of water in swimming pools

The objective of this study was to determine which chemical treatment used for disinfecting water in indoor swimming pools had the least impact on users' perceptions of health problems, and which generated the greatest satisfaction with the quality of the water. A survey on satisfaction and perceived health problems was given to 1001 users at 20 indoor swimming pools which used different water treatment methods [chlorine, bromine, ozone, ultraviolet lamps (UV) and salt electrolysis]. The findings suggest that there is a greater probability of perceived health problems, such as eye and skin irritation, respiratory problems and skin dryness, in swimming pools treated with chlorine than in swimming pools using other chemical treatment methods. Pools treated with bromine have similar, although slightly better, results. Other factors, such as age, gender, time of day of use (morning and afternoon) and type of user (competitive and recreational), can also affect the probability of suffering health problems. For all of the above, using combined treatment methods as ozone and UV, or salt electrolysis produces a lower probability of perceived health problems and greater satisfaction.

女性主义伦理学视野下道德教育的性别和谐

女性主义伦理学研究表明,道德是有“性别”之分的,男女两性在道德价值重心、思维方式和发展方式上均有差异。但道德教育理论和实践中客观存在的性别歧视,导致道德教育的性别失衡和性别冲突,从而限制了道德教育的发展。实现道德教育的性别和谐应该消除性别歧视,重新定义道德和有道德的人,使道德教育的核心概念包容女性气质。在此基础上,重建道德教育大厦,使其矗立于理性和情感的根基之上。

A survey on the light-fastness properties of organic-based Alaska Native artifacts

A series of light-fastness tests were conducted on a group of ethnographic objects that will be on exhibit at the Smithsonian Institution Arctic Studies Center, a recent addition to the Anchorage Museum at Rasmuson Center in Alaska. The objects surveyed belong to the collections of the Smithsonian National Museum of Natural History and the Smithsonian National Museum of the American Indian. This work was designed as a feasibility study on the use of a micro-fading tester as a non-contact and non-destructive technique to evaluate the light-stability of materials present in ethnographic collections. A broad range of objects containing a wide variety of materials were selected for the study. The materials investigated included a variety of dyes applied on silk, cotton, and wool substrates along with some unusual materials such as tanned skin and seal gut skin. The results from this investigation have allowed establishing exhibition recommendations taking into consideration the sensitivity of each object, light levels in the museum building, and estimated light exposures based on the duration of the exhibit. The micro-fading tester has proven to be a very useful tool for determining the light-stability of ethnographic materials without causing any harm to the objects. Objects containing equivalent materials are usually classified under a general category based on their probable sensitivity to light. However, micro-fading test results have permitted the detection of dissimilarities among some of these objects, which could be associated to variations in prior fading histories, the quality of raw materials, and different preparation methods.     

Emotions’ management within the Real Madrid football club business model

Recent changes in the sports industry – derived from increasing financial pressures – have led to the update of existing business models. Particularly in football, the dominant clubs develop new business models based on the spectators’ commitment to the sport. Packed stadiums attract more people who consume both the matches and the many other associated goods and services. In an experience economy, the lever is the tapping of their emotions by an increasingly sophisticated value proposal. Groups of passionate supporters lead the way to the establishment of communities with a common interest in the club. Following a qualitative methodology (interviews and other texts’ analysis) our study of the Real Madrid Football Club (RM) business model suggests that one of the biggest football clubs in the world is creating a business model based on the emotions of its supporters. This finding could be useful for other clubs in many different countries.
