Exploring parental factors and their influence on early adolescent sexual health

Black and Hispanic youth experience the largest burden of sexually transmitted infections, teen pregnancy, and childbirth (Hamilton, Martin, & Ventura, 2011). Minority youth are disporportionately more likely to sexually debut at every age and debut before the age of 13 compared to whites (Centers for Disease Control and Prevention, 2011). However, there is little known about pre-coital sexual activity or protective parental factors in early adolscent minority youth. Parental factors such as parent-child communication and parental monitoring influence adolescent sexual behaviors and pre-coital sexual behaviors in early adolescence. Three distinct methods were used in this dissertation. Study one used qualitative methods, semi-structured, in-depth, individual interviews, to explore parent-child communication in African American mother-early adolescent son dyads. Study two used quantitative methods, secondary data analysis of a cross sectional study, to conduct a moderation analysis. For study three, I conducted a systematic review of parent-based adolescent sexual health interventions. Study one found that mothers feel comfortable talking about sex with adolescents, provide a two-prong sexual health message, and want their sons to tell their when they are thinking of having sex. Study found that parental monitoring moderates the relation between parent-child communication and pre-coital sexual behaviors. Study three found that interventions use a variety of theory, methods, and strategies and that no parent-based programs target faith-based organizations, mother-son or father-daughter dyads, or parents of LGBTQ youth. Adolescent sexual health interventions should consider addressing youth-to-parent disclosure of sexual activity or intentions to debut, addressing both parent-child sexual health communication and parental monitoring, and using a theoretical framework.^

Social integration, health behaviors and health status among Mexican-American women in the *southwestern United States

Using the Hispanic Health and Nutrition Examination Survey (HHANES), this research examined several health behaviors and the health status of Mexican American women. This study focused on determining the relative impact of social contextual factors: age, socioeconomic status, quality of life indicators, and urban/rural residence on (a) health behaviors (smoking, obesity and alcohol use) and (b) health status (physician's assessment of health status, subject's assessment of health status and blood pressure levels). In addition, social integration was analyzed. The social integration indicators relate to an individual's degree of integration within his/her social group: marital status, level of acculturation (a continuum of traditional Mexican ways to dominant U.S. cultural ways), status congruency, and employment status. Lastly, the social contextual factors and social integration indicators were examined to identify those factors that contribute most to understanding health behaviors and health status among Mexican American women.^ The study found that the social contextual factors and social integration indicators proved to be important concepts in understanding the health behaviors. Social integration, however, did not predict health status except in the case of the subject's assessment of health status. Age and obesity were the strongest predictors of blood pressure. The social contextual factors and obesity were significant predictors of the physician's assessment of health status while acculturation, education, alcohol use and obesity were significant predictors of the subject's assessment of health status. ^

Ethnic comparisons of adolescent sexual risk -taking and preventive behavior

For adolescents, unprotected sexual intercourse is the primary cause of sexually transmitted disease (STD), including Human Immunodeficiency Virus (HIV) infection (virus which causes Acquired Immunodeficiency Syndrome (AIDS)), and pregnancy. Although many studies on adolescent sexual behavior have addressed racial/ethnic differences, few studies have examined the relation between race/ethnicity while controlling for other sociocultural and psychosocial variables. The purpose of this study is to examine the relationship between racial/ethnic categories and selected sociocultural and psychosocial variables, with reported adolescent sexual risk-taking and preventive behavior.^ A self-administered questionnaire was used to collect information from 3132 students in a Texas school district (Section 3.5.2). The instrument contained approximately 100 questions on demographic characteristics, sexual behavior, and psychosocial determinants of sexual behavior. Based on the findings of this study, the following major conclusions are made: (1) There are differences in reported sexual risk-taking and preventive behavior among Black, Hispanic and White adolescents in this study. The stratified analysis by gender further suggests significant gender differences in reported sexual behavior among the three racial/ethnic groups. (2) Gender, living arrangement, academic grades, and language spoken at home modified the association between reported sexual risk-taking and preventive behavior and race/ethnicity in this study. This suggests that these sociocultural variables should be considered in future research and practice involving multicultural populations. (3) There are differences in selected psychosocial determinants among the three racial/ethnic groups and between males and females. These differences were consistent with the reported sexual risk-taking and preventive behaviors among race/ethnicity and gender for adolescents in this study. The findings support the consideration of psychosocial determinants in research and interventions addressing adolescent sexual behavior among different racial/ethnic groups.^ Based on the results of this study, two recommendations for practice are made. First, health professionals developing interventions for adolescents from different cultural backgrounds and gender need to be familiar with the specific sociocultural and psychosocial factors which will reduce risky sexual behavior, and promote protective behavior. Second, the need for immediate, realistic, and continuous HIV/STD and pregnancy prevention programs for children and adolescents should be considered. ^

The impact of school year work on adolescent *development

In recent decades, work has become an increasingly common feature of adolescent life in the United States. Once assumed to be an inherently positive experience for youth, school year work has recently been associated with several adverse effects, especially as the number of hours of weekly work increases. The purpose of this dissertation was to describe the impact of school year work on adolescent development in a sample of high school students from rural South Texas, an area where economically-disadvantaged and Hispanic students are heavily represented.^ The first study described the prevalence and work circumstances of 3,565 10$\rm\sp{th}$ and 12$\rm\sp{th}$ grade students who responded to anonymous surveys conducted in regular classrooms. The overall prevalence of current work was 53%. Prevalence differed by grade, college-noncollege-bound status, and parent education. Fifty percent of employed students worked to support consumer spending.^ The second study examined the effects of four levels of work intensity on the academic, behavioral, social, mental and physical health of students. The following negative effects of intense work were reported: (1) decreased engagement in school, satisfaction with leisure time, and hours of weeknight and weekend sleep, and (2) increased health risk behaviors and psychological stress. The negative effects of intense work differed by gender, grade, ethnicity, but not by parent education.^ The third study described the prevalence of injury in the study population. A dose response effect was observed where increasing hours of weekly work were significantly related to work-related injury. The likelihood of being injured while employed in restaurant, farm/ranch, and construction work was greater than the probability of being injured while working in factory/office/skilled, yard, or retail work when compared to babysitting. Cuts, shocks/burns and sprains were the most common injuries in working teens.^ Students, parents, educators, health professionals and policymakers should continue to monitor the number of weekly hours that students work during the school year. ^

First -year mortality and survival among infants with selected congenital anomalies in Texas, 1995 to 1997

Congenital anomalies have been a leading cause of infant mortality for the past twenty years in the United States. Few registry-based studies have investigated the mortality experience of infants with congenital anomalies. Therefore, a registry-based mortality study was conducted of 2776 infants from the Texas Birth Defects Registry who were born January 1, 1995 to December 31, 1997, with selected congenital anomalies. Infants were matched to linked birth-infant death files from the Texas Department of Health, Bureau of Vital Statistics. One year Kaplan-Meier survival curves, and mortality estimates were generated for each of the 23 anomalies by maternal race/ethnicity, infant sex, birth weight, gestational age, number of life-threatening anomalies, prenatal diagnosis, hospital of birth and other variables. ^ There were 523 deaths within the first year of life (mortality rate = 191.0 per 1,000 infants). Infants with gastroschisis, trisomy 21, and cleft lip ± palate had the highest first year survival (92.91%, 92.32%, and 87.59%, respectively). Anomalies with the lowest survival were anencephaly (5.13%), trisomy 13 (7.41%), and trisomy 18 (10.29%). ^ Infants born to White, Non-Hispanic women had the highest first year survival (83.57%; 95% CI: 80.91, 85.88), followed by African-Americans (82.43%; 95% CI: 76.98, 86.70) and Hispanics (79.28%; 95% CI: 77.19, 81.21). Infants with birth weights ≥2500 grams and gestational ages ≥37 weeks also had the highest first year survival. First year mortality drastically increased as the number of life-threatening anomalies increased. Mortality was also higher for infants with anomalies that were prenatally diagnosed. Slight differences existed in survival based on infant's place of delivery. ^ In logistic regression analysis, birth weight (<1500 grams: OR = 7.48; 95% CI: 5.42, 10.33; 1500–2499 grams: OR = 3.48; 95% CI: 2.74, 4.42), prenatal diagnosis (OR = 1.92; 95% CI: 1.43, 2.58) and number of life-threatening anomalies (≥3: OR = 22.45; 95% CI: 11.67, 43.18) were the strongest predictors of death within the first year of life for all infants with selected congenital anomalies. To achieve further reduction in the infant mortality rate in the United States, additional research is needed to identify ways to reduce mortality among infants with congenital anomalies. ^

Prevalence and risk factors of asthma and work -related asthma among U.S. adults: Data from the Third National Health and Nutrition Examination Survey, 1988--1994

This cross-sectional analysis of the data from the Third National Health and Nutrition Examination Survey was conducted to determine the prevalence and determinants of asthma and wheezing among US adults, and to identify the occupations and industries at high risk of developing work-related asthma and work-related wheezing. Separate logistic models were developed for physician-diagnosed asthma (MD asthma), wheezing in the previous 12 months (wheezing), work-related asthma and work-related wheezing. Major risk factors including demographic, socioeconomic, indoor air quality, allergy, and other characteristics were analyzed. The prevalence of lifetime MD asthma was 7.7% and the prevalence of wheezing was 17.2%. Mexican-Americans exhibited the lowest prevalence of MD asthma (4.8%; 95% confidence interval (CI): 4.2, 5.4) when compared to other race-ethnic groups. The prevalence of MD asthma or wheezing did not vary by gender. Multiple logistic regression analysis showed that Mexican-Americans were less likely to develop MD asthma (adjusted odds ratio (ORa) = 0.64, 95%CI: 0.45, 0.90) and wheezing (ORa = 0.55, 95%CI: 0.44, 0.69) when compared to non-Hispanic whites. Low education level, current and past smoking status, pet ownership, lifetime diagnosis of physician-diagnosed hay fever and obesity were all significantly associated with MD asthma and wheezing. No significant effect of indoor air pollutants on asthma and wheezing was observed in this study. The prevalence of work-related asthma was 3.70% (95%CI: 2.88, 4.52) and the prevalence of work-related wheezing was 11.46% (95%CI: 9.87, 13.05). The major occupations identified at risk of developing work-related asthma and wheezing were cleaners; farm and agriculture related occupations; entertainment related occupations; protective service occupations; construction; mechanics and repairers; textile; fabricators and assemblers; other transportation and material moving occupations; freight, stock and material movers; motor vehicle operators; and equipment cleaners. The population attributable risk for work-related asthma and wheeze were 26% and 27% respectively. The major industries identified at risk of work-related asthma and wheeze include entertainment related industry; agriculture, forestry and fishing; construction; electrical machinery; repair services; and lodging places. The population attributable risk for work-related asthma was 36.5% and work-related wheezing was 28.5% for industries. Asthma remains an important public health issue in the US and in the other regions of the world. ^

El ensayo enfermo : Alcides Arguedas y la radiología

Me propongo estudiar en la ensayística de Alcides Arguedas (Bolivia) el lenguaje que utilizó la formación racial cientificista en Hispanoamérica en los comienzos del siglo XX, algunos años antes de los excesos nazifascistas, cuando fue desacreditado por la opinión pública. Mi precepto primero y desde el que comienzo todo mi estudio es la idea de que raza y discursividad son inseparables, por esto, analizaré la representación verbal que confirmará, por una parte, la artificiosidad de lo postulado como "verdad científica" y, por otra, la complicidad que en la forja de esa ilusión una y otra vez han tenido miembros de lo que Ángel Rama llamó "ciudad letrada". Arguedas, en particular, proyectó la imagen de un sujeto que es capaz de relacionar lo estético, lo político y lo científico, logrando en muchas oportunidades ser la personificación de la conciencia nacional.

Fray Alonso de la Veracruz : ensayo de síntesis

El artículo presenta una síntesis de la obra escrita de Veracruz y, en parte, también de su acción. De tal modo, se exponen sus escritos filosóficos, en materia de lógica (Recognitio Summularum y Dialectica Resolutio) y de filosofía natural (Physica Speculatio), y las relecciones en las que se ocupó de los títulos de la conquista y la condición de los indios (De dominio infidelium y De decimis). También es propósito del trabajo proporcionar, a quien quiera continuar con el tema, una guía de buena parte de la abundante literatura secundaria que se ha ocupado de Fray Alonso de la Veracruz. Veracruz es un importante representante de la escolástica novohispana del siglo XVI, y simboliza el comienzo del trasplante filosófico que bajo el signo de la escolástica se extendería en Iberoamérica hasta el siglo XVIII y parte del XIX.

Pizarrón: una escritura con gruesa letra y tiza blanca sobre la América Hispana

Nos proponemos conmemorar aquí los cien años del nacimiento de uno de los destacados intelectuales del siglo XX, cuya obra fuera ampliamente reconocida en nuestro ámbito cultural: nos referimos al escritor venezolano Arturo Uslar Pietri (1906- 2001) quien dedicara su larga vida a transitar diversos caminos del saber. Publicó su primer artículo periodístico a los catorce años; el último, el de la despedida, en su columna del diario El Nacional, aparecería en enero de 1998. Habían transcurrido setenta y ocho años. Cumplirá este aspecto relevante de su producción desde la mirada que le imprime el comunicador social, tarea que se suma a su labor de educador, en los escritos de la columna semanal que titulara Pizarrón. Dejará registrados así destacados artículos de opinión que darán a conocer las ideas de nuestros grandes hombres, entre los que se encuentra el propio Uslar, al tiempo que contribuyen a formar la opinión pública desde las columnas de la prensa y de este modo procura testimoniar tanto nuestra historia política como los registros más destacados de nuestra cultura.

El pensamiento ensayístico y la historiografía de las ideas filosóficas en una cultura bifronte : algunas consideraciones a partir de José Gaos y Carlos Astrada

En este trabajo analizamos dos momentos significativos de la historiografía de las ideas filosóficas en la problematización de la atribución de primacía del ensayo en el despliegue del filosofar hispanoamericano. Desarrollamos este enfoque en nuestra lectura de las obras de José Gaos y Carlos Astrada.

El concepto de imperio en José Vasconcelos

El hombre siempre ha sentido la necesidad de dejar constancia de sus acciones, especialmente en el ocaso de sus días. El resultado de estas inquietudes produjo el surgimiento de los denominados escritos autobiográficos o autorreferenciales. Se considera aquí el concepto de “imperialismo" de José Vasconcelos (1882-1959), expresado en sus Memorias. El pensador consideró a este tema como uno de los mayores desafíos que debía enfrentar América Latina. Se analiza la relación hegemónica que desarrolló Gran Bretaña con esta región, y posteriormente la de EEUU. Finalmente se desarrolla la solución que ofrece para enfrentar este problema: la defensa de un nacionalismo hispánico.

La filosofía en el plan de estudios del Deán Funes : el contexto hispanoamericano

Se relaciona el Plan de Estudios preparado por Gregorio Funes para la Universidad de Córdoba (1813) con otros similares y contemporáneos elaborados en Santa Fe de Bogotá, Lima y Quito. El interés principal recae en los estudios de filosofía. Los planes representan un momento de transición hacia la modernidad, con la consiguiente crítica a la escolástica y la decisión de reemplazar la física aristotélica.

Tutaque sit inter inprobos innocentia : aspectos teóricos e práticos sobre os limítes da autoridade régia no reino hispano-visigodo de Toledo segundo as fontes júridicas e conciliares do reinado de Chintila (636-640).

Las construcciones teóricas elaboradas a lo largo de la Antigüedad Tardía buscaban, en su gran mayoría, poner en destaque la autoridad y el poder que deberían ser ejercidos por el rey en el espacio geográfico de su reino. Además de la evidente herencia del pensamiento político clásico romano, que ya apuntaba la supremacía teórica del magistrado o del princeps respecto al cuerpo social y político, el modelo cristiano del princeps christianus sacratissimus, que se construye a partir del siglo IV, ofrecía la perspectiva de que el gobernante debería imponer las leyes para hacer valer la justicia a los inocentes. Tales ideas se mantuvieron en el reino hispanovisigodo de Toledo y para tanto tenemos indicios en las fuentes isidorianas, conciliares y leges antiquas. Sin embargo, la antitesis entre teoría y el ejercicio práctico del poder se presenta muy claramente en las disputas nobiliarias afectando directamente el poder del rey y todas sus atribuciones. Es el caso del reinado de Chintila (636-640), en el cuál la ley tenía como principal objetivo la protección de los grupos de apoyo político del monarca.

De la España africana a la América teocrática : notas sobre el ideario de Simón Bolívar

Las ideas de Simón Bolívar sobre América y sobre Europa han recibido alguna atención de los investigadores. Mucho menos las que expresó sobre Asia y África. Aunque fueron marginales a su pensamiento, la reunión de sus alusiones al respecto permite arrojar alguna luz sobre la reflexión de la Independencia y sobre los cambios que el Libertador experimentó en su percepción del naciente mundo que aparecía ante sus ojos. Partiendo de una actitud orientalista y despectiva inicial, con el tiempo llegó a pensar que el Oriente no podía descartarse como influencia en las instituciones americanas.

El comercio librario y la transmisión de la filosofía a Hispanoamérica : (siglos XVI al XVIII)

La transmisión de la filosofía al continente americano puede rastrearse materialmente por medio del examen de las redes comerciales que procuraron la numerosa llegada de libros que alimentaron a las primeras bibliotecas coloniales. En ellas se resguardaron variadas obras filosóficas y humanísticas fueron fundamentales en la promoción y desarrollo de la cultura escrita y la educación. Al revisar algunos aspectos centrales del comercio, el control librario y la colección de obras afines en las primeras bibliotecas privadas y religiosas, se pretende reconstruir al menos en sus rasgos característicos el devenir de la filosofía en el Nuevo Mundo.
