Occurrence and Distribution of a Diatom-Diazotrophic Cyanobacteria Association during a Trichodesmium Bloom in the Southeastern Arabian Sea

Symbiotic diatom-diazotrophic cyanobacteria association (DDA) of Rhizosolenia hebetata and Rhizosolenia formosa with endosymbiotic cyanobacteria Richelia intracellularis was noticed and documented for the first time during a bloom of the cyanobacterium Trichodesmium erythraeum in the oligotrophic shelf waters along Kochi and Mangalore transects, southeastern Arabian Sea (SEAS), during spring intermonsoon (April 2012). Although the host is frequently seen, the symbiont is rarely reported in the Indian EEZ. The presence of nitrogen-fixing symbiotic association of Rhizosolenia-Richelia along with Trichodesmium erythraeum highlights the significance of DDAs on the nutrient and energy budgets of phytoplankton in the oligotrophic environments of the Arabian Sea during spring intermonsoon

Role of the cultural values as a key part in the implementing of healthy practices : exploratory research

El concepto de organización saludable cada vez toma más fuerza en el ámbito empresarial y académico, a razón de su enfoque integral y al impacto generado en distintos grupos de interés. Debido a su reciente consolidación como concepto, existe un limitado cuerpo de investigación en torno al tema. Para contribuir a la generación de conocimiento en este sentido, se desarrolló un estudio exploratorio el cual tenía como objetivo identificar la relación existente entre la implementación de prácticas saludables en las organizaciones y los valores culturales. En el estudio participaron 66 sujetos a quienes se les administró un cuestionario compuesto por nueve variables, cinco provenientes del modelo de Hofstede (1980) y cuatro más que evaluaban la implementación de prácticas organizacionales saludables. Los resultados obtenidos muestran que los valores culturales predicen la implementación de prácticas saludables.

The playful as a psycho-pedagogic method: one experience in preventing youth drug dependence

This participatory action research was based on a experience of educational intervention on La Cruz and Bello Oriente (Manrique-Medellin), a marginal zone in the northeastern part of the Commune 3 in Medellin,. Colombia. In this marginal sector, psychosocial problems seem to be associated to limited educational and employment opportunities, domestic violence, illegal armed forces, sexual abuse, social discrimination, and lack of adequate public services, among others.  All these are also considered as risk factors for drug dependency.  We used a structured interview designed to identify leisure tendencies, use of free time, and tendencies in recreational activities. Data from the interview were triangulated with information collected by observation and in field work and used to build a psycho-pedagogic method based on play and leisure activities. The effects of the use of this educational intervention on the satisfaction of human needs were analyzed in light of the theory of Manfred Max-Neef. Results point out the need for new educational strategies aimed to promote creativity, solidarity, mental, physical and social health, more enthusiasm and motivation and in general, positive attitudes that help prevent drug dependence.

Sleep quality perception in youth population

To assess sleep habits and sleep quality perception in a Colombian and Mexican youth sample. Materials and methods: following a sleep diary methodology with a questionnaire of 27 categorical and quantitative items, the assessment was done immediately upon awakening. Results: it was applied to 317 high school (n= 189) and undergrads (n= 128) in Bogotá, Colombia (n= 197) and México City, México (n= 120); 147 females (46,4%) and 170 males (53,6%). The mean age was 18,6 ± 2,81 years with a median and mode of 17 years. The Cronbach’s alpha obtained from 135 measurements during the study period was 0,86 and 0,57 from the mean values of 27 scale items. An inverse correlation was found between hours of sleep per night and number of naps (r= -0,12; p= 0,029); 38% of participants did not nap and slept on average 7,6 night hours or more (X2= 2,78; p= 0,047). The men took more naps than women (men 76,5%; women 55,6%; X2= 15,26; p= 0,000). A reduction of hours of sleep per night and the need for naps was significantly associated with participants’ gender. The mean and median hours of sleep per night (7,2 hours) was used to classify the population into two groups: sleep (+) 7,3 or more hours and sleep (-) 7,2 hours or less. These groups were compared. Conclusions: youth population evaluated showed a reduction of hours of sleep per night was found. This was associated to naps frequency and participant gender.
