Psychology (PSYCH) , 2019, DOI: 10.4236/psych.2019.104028
Abstract: This study analyzes the relationship between self-esteem, in secondary school students, mainly of rural origin, with the ethnic condition, taken into consideration for this purpose the use of the language, in which we compare the Mayan speakers and non-Mayan speakers of a region of Yucatan, Mexico, in men and women. Quantitative, cross-sectional study, with a simple random sample of 1452 Yucatan high school students, by means of a self-administered questionnaire. The main results are that 22% of the population has a low self-esteem level, with significant differences by age (p = 0.028) and in negative self-esteem score in the variable Maya-speaker and not Maya-speaker (p = 0.023). There were also differences between the condition of rural and urban. The prevention and care of mental health in adolescence must take into account the peculiarities of cultural contexts and gender determinants, to strengthen the autonomy and self-esteem of new generations, educational programs based on studies that take into account the determinants social gender and ethnicity, now blurred before the global communication processes.
Los múltiples rostros de la pobreza en una comunidad maya de la Península de Yucatán
Robles-Zavala, Edgar;
Estudios sociales (Hermosillo, Son.) , 2010,
Abstract: the aim of this study is to rescue the voice of the most impoverished and marginalized households in a mayan community in the yucatan peninsula. the study adopted the sustainable livelihoods approach as the analytical framework, which identifies the assets of the households, the institutional constraints that determine the access of these assets, as well as the vulnerability contexts determined by external factors to the households or the community. qualitative and quantitative techniques were used to analyze the discourses of 70 households. the study concluded that poverty in the households is closely linked to the institutional structure which has limited the development capabilities in the community. the institutional constraints include corruption, and a lack of institutional ability to determine the real needs of the community. these problems may be addressed through local participatory policies.

The Yucatan Peninsula’s groundwater is experiencing increases in degradation due to swelling population and tourism; yet little is known about sources and transport of contaminants in drinking water supplies. The karst allows for rapid transport of microbial and chemical contaminants to the subsurface, resulting in significantly increased potential for pollution of groundwater. The objective of this research is to determine the occurrence, source, and extent of fecal contamination in the Tulum region of the Peninsula. A multi-analytical approach was undertaken in impacted and unimpacted groundwater locations; measurements included physicochemical parameters, total coliform and E. coli, Bacteroides (human vs total) and caffeine. The results indicate a variation in geochemistry from impacted to protected sites. The total coliform and E. coli show fecal contamination is wide spread. However, the presence of human Bacteriodes and caffeine in the water in the Tulum well field indicates that the recent human activities next to the well field are impacting the drinking water supply. This project is an assessment of the area’s current water quality conditions and the probable impact that the aforementioned growth would have on the area’s water supply. By applying multiple source parameter measurements, including molecular microbiology and chemical indicators it was confirmed the extent of fecal contamination of human origin covered the entire sampling region.

Abstract: Borna Disease Virus (BDV) causes a progressive non-suppurative meningoencephalitis that sometimes occurs in mortality; this disease has been reported for over two centuries ago in horses, sheep and cats in Central Europe and some regions of Asia. Currently, it is known that it causes neurological symptoms in various species of vertebrates including human beings. In Yucatan, Mexico, there is a single serological report about the circulation of BDV in schizophrenia patients; however, nothing is known about the circulation in animals. We obtained serum samples of 100 horses without apparent clinical signs caused by BDV infection, from various sites in the region. Antibodies against BDV were detected by electrochemiluminescence immunoassay (ECLIA) method with three recombinant proteins: BDV p24, BDV p40 and BDV p10 as antigens; obtaining a high seroprevalence of 44% (44/100). This study generates the first report of the probable activity of the BDV in healthy horses in Mexico and has expanded the infiltration area of BDV in the world. Nevertheless, several molecular investigations are required to detect BDV-RNA circulating and find sequences for clarification of the origin of BDV in Mexican horses.

Psychology (PSYCH) , 2016, DOI: 10.4236/psych.2016.714175
Abstract: Registration of deaths classified as femicide, is an issue that occupies a breach of law, and that in this matter inconsistencies and absences in the information generated persist and persist in popular culture a strong stigma that various social groups and affected (victims) lead to underreporting of gender violence. Documentary research that conducted to determine the association of geographic areas and social factors related to violence to women occurred in the state of Yucatan during 2004 to 2014. Of the major findings of this study are: there are significant differences in the presence of domestic violence with the economic sector with a value of the test statistic of 13,500 with two degrees of freedom, a significant difference with a P-value of 0.001 (P-value < 0.05) was obtained, and P-value 0.000 (P-value < 0.05) for the murders of women. Geospatial distribution shows that the municipalities highest number of cases reported are found in large cities, and related to the three sectors of economic activity. Geographical distribution is North, South and East of the state. We conclude that it is required to have a surveillance system for the prevention of gender violence, also provide therapy to both men and women who have lived or have used violence systematically and taught by trained and sensitive to provide such care staff, and thus prevent deaths from gender violence.

Yolanda Oliva Pe?a, Andrés Santana Carvajal, Luis Cambranes Puc, Ricardo Ojeda Rodríguez
Psychology (PSYCH) , 2018, DOI: 10.4236/psych.2018.915168
Abstract: The objective of this work was to determine the magnitude and frequency of school violence in the eastern part of the state of Yucatan, Mexico, which is populated primarily by Maya-speakers and also by communities of high social marginalization, factors associated with adolescence, and the condition of gender, by contexts that have been poorly documented in the face of the phenomenon of violence in secondary schools. Quantitative study through a self-applied survey of 1432 high school students is possible to conclude that the conditions of gender, social and ethnic marginalization are elements that come together in vulnerabilities to present violence in social contexts with a strong magnitude. The students show similar proportions of violence in to teachers (93%), a significant difference in women than the recorded by men (p = 0.000), with a greater number of cases in moderate and severe intensity. Peer violence is manifested a statistically significant difference by men and women, in which women reflect a greater intensity, with a higher number of cases in violence of moderate and severe intensity (p = 0.000).

Spatial and temporal structure of fish assemblages in a hyperhaline coastal system: Ría Lagartos, Mexico
Peralta-Meixueiro, Miguel Angel;Vega-Cendejas, María Eugenia;
Neotropical Ichthyology , 2011, DOI: 10.1590/S1679-62252011005000033
Abstract: the spatial and temporal fish species assemblages were analyzed throughout two annual cycles (2004-2005 and 2007-2008) in the ría lagartos lagoon system, mexico, via non-parametric multivariate analyses. we compared density and biomass of fish species among five habitat types defined by combinations of structure and environmental characteristics (hyperhaline, rocky, seagrass, channel, and marine), and three climatic seasons (dry, rainy, and northerlies). a total of 11,187 individuals distributed in 32 families and 63 species were collected. the most numerically abundant species were floridichthys polyommus and cyprinodon artifrons, while sphoeroides testudineus contributed to the greatest biomass. species composition consisted mainly of estuarine and euryhaline marine species. spatially, a saline gradient was observed with marine conditions in the mouth, and increasing to over 100 in the inner zone of the system. species richness, diversity and biomass declined from the mouth to the inner zone, while density showed an inverse tendency, with the highest values in the inner zone. thus the salinity was the variable that best explained the spatial fish assemblages" structure. the ichthyofauna composition did not change over time, but the dominant species varied with the years. the abundance of juvenile specimens, suggest that the different habitats are used as feeding and breeding zones; hence it is proposed that protection strategies be pursued not only for the lagoon system but also for the northern zone of the yucatan peninsula.

Abstract: the objective was to analyze the abundance and distribution of snappers and groupers in the yucatan shelf. we analyzed forty-five samples of ichthyoplankton that were taken from oceanographic research (yucatan03-a) during september 2003. superficial tows were made with a bongo net. a total of 3,963 organisms were collected, they belong to 50 fish families. three families (carangidae, gobiidae y clupeidae) represented more than 50% of the density. lutjanidae and serranidae families were within the nine most abundant families, with a total density of 713.8 ±60 org./100 m3. serranidae family is represented by species of the genus anthias, diplectrum, epinephelus, liopropoma, serranus and epinephelus fulvus, whereas lutjanidae is represented by lutjanus analis, l. campechanus, l. griseus and l. synagris. the highest density species was l. synagris, representing 28.9% of material reviewed, followed by e. fulvus, l. analis and l. campechanus. the analysis of the cluster of stations allowed identifying three oceanographic zones at a horizontal level: west, center and upwelling (in the east). the groupers larvae were distributed mainly in the center whereas snappers larvae were distributed in the east of the shelf, this suggests that the spawning of these families occurred in different parts of the shelf, avoiding in this way the competition for food in their first larval stages. the current of yucatan promotes an ekman transportation that produces an upwelling that generates an increment of phytoplankton, zooplankton and ichthyoplakton that favors the fish recruitment, a fast growth and a diminution of their larval stage.
