The purpose of the present article is to make a critical analysis to the dominant classic epidemiological positionthat explains health-disease duality from genetics and lifestyles. It talks about how political, economic, cultural,environmental and demographic structure are strongly influenced by the social determinant of health, related tosanitary inequities, which may pose barriers to the adoption of healthy lifestyles, especially to people in extremepoverty, armed conflict, disasters and other hard conditions, which are prevailing circumstances in low andmiddle income countries. It discusses the need to transcend the paradigm of health education which is highlyprescriptive and does not offer the expected results. The research is documentary, and was based on a journalisticliterature review. It concludes that it is necessary to transcend into a holistic paradigm to explain the healthdis...

Proteins are versatile biopolymers in living systems that show a great diversity of functions based on the order of their amino acids. Many protein functions, whether mechanical or regulatory, emerge from interactions with other proteins and macromolecules. This dissertation describes the development and adaptation of new computational models to investigate structural and dynamic properties of protein interactions. Two main systems were investigated: the regulation of the actin cytoskeleton and the control of DNA transcription by nuclear factor B (NF-kB). During the study of the regulation of the actin cytoskeleton, mechanical and dynamic properties were estimated using polymer theory. A simplified model of actin filament polymerization was developed. Through simulations, it was shown that actin networks containing Arp2/3 undergo abrupt releases of tension. For the study of DNA interacti...

Background: Trolling is a very topical phenomenon, but much less studied unlike other problems related to new technologies. The present study evaluated the levels of trolling in adults from sadism and internet addiction. Method: For this purpose, an intentional sample of 708 adults of both genders (56% women, age M = 25 years SD = 8.7), from the Autonomous City of Buenos Aires (CABA) and Greater Buenos Aires (GBA), Argentina is selected. Participants answered the Trolling Questionnaire by Buckels et al., On Sadistic Tendencies by Paulhus et al., On Internet Addiction by Lam-Figueroa et al. and a demographic questionnaire. The data indicated that both vicarious sadism, outright sadism, and dysfunctionality in Internet use were predictors of trolling. Results: The results suggested an association of trolling with age and differences according to gender. A structural model to predict trolli...

In recent years, climate change has doubled its impact worldwide due to different anthropogenic activities, altering the climatic variability of atmospheric elements and meteorological phenomena that play a relevant role in establishing life on the planet. Thus, the behaviour of climatic elements was evaluated and analysed between the period 2000-2020 in the provinces of Chupaca, Huancayo and Concepción del Valle del Mantaro, by means of the synoptic climatology method using MATLAB software to process hydrometeorological data (TX, TI, RR and RH) provided by SENAMHI. The behaviour of these variables resulted in an increase from -0.5°C to 6°C of TI, TX increased the value of the year 2000-2020 with a +6°C and the amplitude of the values of the distribution of the whisker box, regarding RR from the year 2011-2020 the value of 500 mm decreased to 200 mm in the station "F" while the value...

In the media industry, fast innovations and increasing competition require a high degree of corporate leadership (Koryak, Mole, Lockett, et al., 2015). The study of leadership appears to be an increasingly relevant issue. This research aims to find out to what extent leaders (editors and publishers) behave and understand their roles in Chilean and Spanish newsrooms. A questionnaire was applied to measure and identify leadership traits that are considered crucial, thus making possible to acknowledge transformational leaders and differentiate efficient leaders from ineffective. The results show that editors believe they have the ability to inspire, share goals and understand what is important, in contrast with the working experiences of their employees, that often have a low opinion of media companies as places to work.

Previous studies carried out by Perales et al. in medical students of San Marcos University (SMU), reported global suicidal behavior’s life prevalences (L.P.) (wish to die, suicidal ideation, suicidal plan and suicidal attempt) of 30%; and specifically of suicidal attempt, 4% while in undergraduate social work students were 57.7% and 14.8% respectively. Not having data on this problem in Education and Physical Education’s undergraduate students in Peru the present study is addressed to estimate the life-prevalences of these behaviors in this student population. OBJECTIVE: To identify students of SMU’ Education and Physical Education Schools who had presented suicidal behavior and to estimatethe life prevalence (L.P.) and its associated variables in this population. METHODOLOGY: Analytic, transversal study in the students registered in 2011 in those two Schools. Previously validated...

The present study proposes to characterize the relationship between upbringing styles and ADHD related behaviors. This involved the participation of 46 parents of children belonging to the elementary school Juan A. Mateos, who were asked to respond to the Adaptation of the Parenting Questionnaire, and the survey of diagnostic criteria for Attention deficit disorder and hyperactivity. We performed an X2 test of the data obtained for the variables of upbringing style and suspected ADHD referred by adults (parents and teachers), suggesting a relationship between authoritarian parenting style and non-suspected ADHD by parents, also showing according to the appreciation of teachers a relationship between permissive parenting style and suspected ADHD.

Debate on single-sex vs. coeducational schooling has increased over the last years. The purpose of the following study is to produce empirical evidence on this debate by comparing the frequency of disruptive behaviors in students thatattend single-sex and coeducational schools, in order to find statistical correlation.The frequency of disruptive behaviors in students coming from 5 single-sex schools was compared to that coming from 5 coeducational ones. Data came from 844 students aged 14, attending public schools in Callao, Peru. Students from single-sex schools showed less frequent disruptive behavior in each of the three measured categories—disruptive behaviors, behaviors that show lack of responsibility and anti-social behavior. A weak correlation was found between each of the three categories and the main variable. The study controlled for extraneous variables.

The aim of this study was to analyze the role of different socioeconomic backgrounds in tax compliance behavior at different tax rates. Additionally, we examine the effect of the source of income (whether if it is earned or endowed) on tax behavior. In the first study, students from Argentina and Spain performed an anagram task to earn profits and then they declared their earnings at different tax rates. In the second study, students from Argentina were endowed with an income at the beginning of the experiment and then they declared their earnings at different tax rates. Significant cross-cultural differences were observed at high tax rates. Also, when income was earned, participants declared significant more than when de income was endowed. The results show the importance to consider sociocultural aspects when making public policy and the role of income source in tax behavior.

The present work reports the simulation of a wet scrubber coupled to an UASB reactor. The scrubber consisted of baffles, packed bed of sponge material, an acrylic tube and all the connections necessary to bring the H2S‐ladden biogas. The purpose of the equipment is to eliminate some of the gases coming out of the reactor, through their oxidation by the dissolved oxygen provided by the microalgae present in the water from the tertiary lagoon. Hydrogen sulfide is a foul‐ smelling and toxic gas which can cause death at high concentrations, and can also cause damage to the structures with which it comes into contact. The scrubber was installed on the site of CITRAR‐UNI and the behavior of the equipment was monitored during three weeks by following the temperature, pH and the concentrations of sulfates and dissolved oxygen. The results have shown that the scrubber was effectively an oxi...
