Perceptions of Interscholastic Equestrian Association Members Regarding the Take the Reins Magazine: a Readership Study

Guided by the uses and gratifications theory, the researcher sought to determine the Interscholastic Equestrian Association (IEA) members' self-reported readership behaviors and perceptions of the Take the Reins magazine. The population included dues-paying members of the IEA who reported an accessible email address (N = 9,203). The initial email was sent to the population of which 463 were invalid due to frame errors, leaving the accessible population of N = 8,740. A total of 1,043 individuals participated in the questionnaire for a response rate of 11.9%. Descriptive survey research methodology was used to collect and analyze perceptions of readers regarding content, design, utility, and overall perception of the magazine. Data was collected via an online Qualtrics instrument in March 2014. The typical respondent is a 17-year-old female member who receives Take the Reins magazine and is primarily active in Hunt Seat equitation. IEA members perceive the magazine's general appearance and quality of photos and illustrations to be good. They perceive the magazine's content to be good in regard to the range and variety of topics, understandability of information, and quality of writing. To some degree, IEA members perceive the magazine to portray information accurately and objectively. They are most interested in stories about IEA events and horses. Overall, they are impressed with the magazine. IEA members do not wish for the magazine to be offered via the Internet. Additional research should be conducted to evaluate why the members have these perceptions.Agricultural Educatio

Potencial hidrogeniônico de antimicrobianos, segundo os fatores ambientais temperatura e luminosidade

The objective of this experimental study was to measure the pH of antibiotics administered by intravenous infusion - ceftriaxone sodium, vancomycin hydrochloride, metrodinazole, penicillin G potassium and amikacin sulfate - after reconstitution with sterile water and dilution with NaCl 0.9% or dextrose 5% in water, according to temperature and luminosity of the environment. The results showed that variation in the drugs' pH was less than 1.0 value and that some antibiotics remained acidic after dilution and maintained this chemical profile in all situations studied, suggesting that the studied environmental factors did not change the solutions' acid base characteristic. Some pH values measured characterize risk for the development of chemical phlebitis and infiltration, and it is important for clinical practice to emphasize the profile of intravenous solutions of antibiotics, considering method of dilution, and time to infusion.El objetivo de este estudio experimental fue medir el pH de los antibióticos de administración intravenosa ceftriaxona sódica, clorhidrato de vancomicina, metronidazol, penicilina G potásica y sulfato de amikacina, después de reconstitución con agua destilada y dilución con NaCl a 0,9%, o suero glucosado a 5%, considerando la influencia de la temperatura y luminosidad ambientales, así como el tiempo de exposición, en el comportamiento químico de esos fármacos. Los resultados demostraron variaciones que no ultrapasaron 1,0 (valor de pH) y que algunos antimicrobianos, eminentemente ácidos después de la dilución, mantuvieron ese comportamiento en todas las situaciones estudiadas, no sugiriendo la influencia de factores ambientales en el comportamiento químico de las soluciones. Considerando que algunos valores de pH encontrados pueden contribuir para el desarrollo de flebitis química e infiltración, es importante enfatizar que para la práctica clínica en salud, existe la necesidad de conocer las características de las soluciones de infusión intravenosa, considerando el tipo de dilución y el tiempo de infusión.O objetivo deste estudo experimental foi medir o pH dos antibióticos de administração intravenosa ceftriaxona sódica, cloridrato de vancomicina, metronidazol, penicilina G potássica e sulfato de amicacina, após reconstituição com água destilada e diluição com NaCl 0,9%, ou soro glicosado 5%, considerando a influência da temperatura e luminosidade ambientais, assim como do tempo de exposição, no comportamento químico desses fármacos.
