La medicina de la educación física y el deporte en España (1940-2002) : aproximación bibliométrica

[ES] Actualmente el análisis de la producción científica es objeto de atención de estudiosos/as que, con las limitaciones propias de todo sistema de evaluación, proponen la utilización de unos indicadores para conocer la productividad de los/las científicos y el impacto de sus actividades. La productividad científica de un investigador/a se mide generalmente por el número de artículos originales de investigación que pública, el número de patentes o el desarrollo y aplicación de nuevas técnicas. Habrá que considerar con cautela que la cantidad no significativas calidad. La presión que el investigador/a sufre sobre todo en el ámbito académico, puede provocar distorsiones en el análisis. Sin embargo como mínimo la producción de un científico significa que éste cara a la investigación es activo. El por qué de este tipo de análisis y su implantación en la evaluación investigadora, viene determinado por intentar tener unos indicadores que midan e interpreten el conocimiento científico y su crecimiento. La información básica la ofrecen las publicaciones y la aplicación a éstas de técnicas bibliométricas. Los indicadores bibliométricos se dirigen a medir la cantidad, impacto y significado de la producción científica. Deben manejarse teniendo en cuenta siempre sus limitaciones. Un trabajo se considera más o menos importantes y tiene la posibilidad de ser difundido más o menos rápidamente en función de la revista donde se publique. El rigor más o menor exigente de los filtros de los manuscritos, hacen que la publicación un recursos con una calidad determinada. Un número alto de citas de los trabajos presuponen una contribución al conocimiento. Pero el simple recuento de publicaciones tiene defectos, no se tiene en cuenta la creatividad, la influencia y la calidad de los conocimientos que contienen.

A corpus of Middle English medical prologues in the Sloane Collection of The British Libray: an introduction to the genre in prose

[ES] Esta tesis trata sobre los prólogos a textos ingleses de carácter médico escritos o copiados en forma de prosa durante el siglo XV. En este trabajo se han contemplado dos objetivos generales: por un lado, la creación de un corpus con todos los prólogos inéditos que cumplen con estos criterios y que se encuentran en la colección de Sloana en la British Library de Londres, según Voigts & Kurtz: Scientific an Medical Writtings in Old and Middle English: An Electronic Reference (2000); y por otro, la presentación de estod prólogos como conjunto, incluyendo: los datos recopilados sobre la codicología de los manuscritos, afiliación de los textos, sus fuentes y el dialecto utilizado. Asimismo, como parte de esta presentación, se aporta un análisis original de la estructura, forma y contenido de los materiales seleccionados para el estudio. El propósito de esta tesis es llenar un hueco en la literatura académica acerca de los prólogos a textos médicos escritos en inglés medieval tardío, tal y como lo señala Voigts (1982:54)

CAMINOS ANTIGUOS DEL NUEVO MUNDO Bolivia - Sudamérica, Siglos XIV - XVII, através de fuentes arqueológicas y etnohistóricas

La tesis "CAMINOS ANTIGUOS DEL NUEVO MUNDO Bolivia - Sudamerica, Siglos XV - XVII, através de fuentes arqueológicas y etnohistóricas", expone una compleja red vial en el territorio hoy conocido como Bolivia: corazón de Sudamérica (llamado así por su posición central en el subcontinente. Es el primer estudio arqueológico-histórico sobre el transporte en Bolivia, un vasto territorio, conocido por los Inkas (Siglo XIII) como Antisuyu y Collasuyu, una tierra desconocida, inexplorada, montañosa y selvática, poblada por diversas culturas, que habían desarrollado un sistema de tráfico fluvio-terrestre, que les permitiera recorrer tan extenso y contrastado territorio entre Andes y Amazonía. Los españoles le llamaban Alto Perú hacia el 1538, creando en 1559 la Real Audiencia de Charcas principal institución del Alto Perú, que pertenecía al Virreinato del Perú hasta 1776, año en el que se crea el Virreinato del Río de La Plata y el Alto Perú pasa a ser parte de este último. El Alto Perú se independiza de la Corona española en 1826, creándose la República de Bolivia. Sobre la base del primer mapa de Bolivia de 1859, en el que se hace un primer levantamiento de las redes camineras y la complementación con mapas más antiguos del Archivo General de Indias de Sevilla, se desarrolla el presente estudio, complementado con trabajos arqueológicos en la región e investigaciones en los Archivos Históricos de La Paz, Tarija, Santa Cruz y Buenos Aires que contienen manuscritos coloniales inéditos anexados en la presente tesis . El estudio es un aporte importante en el estableciemiento del Qapacñan o Caminos reales y sagrados de los Inkas, por cuanto Bolivia siendo un territorio central en Sudamérica fue un enclave cultural no solo en el periodo inka sino también pre inka. El estudio apunta a conocer la real dimensión del periodo prehistórico inka y pre inka en la región, en cuanto la mayoría de las vías actuales o  modernas, se encuentran sobre un trazado antiguo cuyos restos conservan aún la construcción formal de la ingenieria inka o pre inka. Las fuentes etnohistóricas que complementan la investigación corresponden principalmente a los siglos XV a XVII e información arqueológica concerniente al Periodo Inka (siglos XIV – XV aprox.).

Il Lessico d’amore nei primi tre libri delle Odi di Orazio

Il presente studio si è posto come obiettivo quello di redigere un lessico dei termini d’amore nella poesia di Orazio, e, specificamente, dei lemmi presenti nei primi tre libri delle Odi. L’interesse per la lirica del Venosino ci ha indotti ad affrontarne la lettura non solo considerando quelle che sono le tematiche diremo topiche della sua poetica ( modus, angulus, mors, tempus, cura, solo per citare quelle più significative ), ma anche quelle meno note, quale appunto il tema dell’amore, oggetto di questo lavoro. Si è proceduto così all’analisi di ogni singolo libro di ogni ode, catalogandone ed analizzandone rispettivamente tutte le occorrenze di quei termini che abbiamo ritenuto essere propri del lessico amoroso. Il commento ad ogni libro è stato supportato dagli studi di Nisbet-Hubbard per il primo ed il secondo libro delle Odi ( cfr. R.G.M. Nisbet-M. Hubbard, A commentary on Horace: Odes Book 1, Oxford 1970; R.G.M. Nisbet-M. Hubbard, A commentary on Horace: Odes Book 2, Oxford 1978 ) e Nisbet-Rudd per il terzo ( cfr. R.G.M. Nisbet-Rudd, A commentary on Horace: Odes Book 3, Oxford, 2003 ). Trattandosi di un lessico è stato altresì fondamentale il contributo dell’ Index uerborum amatorium ( Cfr. R. Pichon, De sermone amatorio apud Latinos elegiarum scriptores, Paris 1902 ) e del ThLL. Si è infine proceduto ad individuare quei termini maggiormente significativi nell’ambito della poesia d’amore in generale, il cui riflesso è presente anche nella poesia oraziana, con una particolare attenzione al rapporto che intercorre tra Orazio e la tradizione neoterica ed elegiaca e al lessico dei colori, che vanta numerose occorrenze nella poesia d’amore, soprattutto in riferimento alla bellezza muliebre e maschile e che quindi appare di rilevante importanza per comprendere l’estetica della poesia oraziana nel ritrarre la forma degli amanti che popolano i suoi più celebri versi d’amore.

America's Shifting Color Line? Reexamining Determinants of Latino Racial Self-Identification

Objectives. Latinos are the nation's largest minority group and will double in size by 2050. Their size coupled with the fact that Latinos do not constitute a separate race raises questions about Latinos' incorporation into the U. S. racial hierarchy. This article explores patterns of Latino racial identity formation, examining the determinants of racial identity. Methods. Using the 2006 Latino National Survey, I estimate multinomial logit and ordered probit models of identification choices. Results. Latino racial identity is strongly associated with several factors, including socioeconomic status, measures of perceived discrimination and commonality, and measures of acculturation/assimilation. Most Latinos have a broader, more complex understanding of race. Furthermore, some Latinos do believe that they occupy a unique position in the racial hierarchy. Conclusions. The results suggest that the color line W. E. DuBois argued has long divided our nation may eventually shift.

Spanish-English Codeswitching in Email Communication

While spoken codeswitching (CS) among Latinos has received significant scholarly attention, few studies have examined written CS, specifically naturally-occurring CS in email. This study contributes to an under-studied area of Latino linguistic practices by reporting the results of a study of CS in the emails of five Spanish-English bilingual Latinos. Methods are employed that are not often used in discourse analysis of email texts, namely multi-dimensional scaling and tree diagrams, to explore the contextual parameters of written Spanish-English CS systematically. Consistent with the findings of other studies of CS in CMC, English use was most associated with professional or formal contacts, and use of Spanish, the participants’ native language, was linked to intimacy, informality, and group identification. Switches to Spanish functioned to personalize otherwise transactional or work-related English-dominant emails. The article also discusses novel orthographic and linguistic forms specific to the CMC context.

Latino Teen Pregnancy in Texas: Prevalence, Prevention, and Policy

Texas is home to over one million Latino teens who are at risk for negative reproductive health outcomes, such as teen pregnancy and STIs. Teen pregnancy disproportionately impacts the health of Latino teens in Texas and places them at risk of continued high rates of poverty, school dropout, and unemployment unless Texas makes a concerted effort to reduce its teen pregnancy rate. The birth rate among Latina girls is astonishing: 98 per 1000 Latinas (aged 15-19) are giving birth. This translates to over 32,000 births each year among Latina teens, costing almost $98 million in direct medical expenditures and well over $638 million if other costs are included. Most teens become sexually experienced while they are of school age, which translates to an estimated 414,583 sexually experienced Latino students attending Texas public schools. Of these Latino youth, 237,466 report being currently sexually active, and 89,000 report having had four or more sexual partners in their lifetime. While causes of teen pregnancy are complex, the solutions to teen pregnancy are known. Texas needs an effective, comprehensive approach to address the sexual health needs of Texas Latino youth that includes: statewide implementation and monitoring of evidence-based sex education for middle school and high school students, access to reproductive health services for students who are already sexually experienced, and widespread training on adolescent sexual health for teachers, service providers, and parents. By tackling teen pregnancy, we can positively impact the future and well-being of not only Latinos, but of all Texans, and subsequently can contribute to the social and economic success of Texas.

Ethnic Minority Children’s Active Commuting to School and Association with Physical Activity and Pedestrian Safety Behaviors

Background: Children's active commuting to school, i.e. walking or cycling to school, was associated with greater moderate-to-vigorous physical activity, although studies among ethnic minorities are sparse. Objectives: Among a low-income, ethnic minority sample of fourth grade students from eight public schools, we examined (1) correlates of active commuting to school and (2) the relationship between active commuting to school and moderate-to-vigorous physical activity. Methods: We conducted a cross-sectional analysis of baseline measurements from a sample of participants (n=149) aged 9-12 years from a walk to school intervention study in Houston, Texas. The primary outcome was the weekly rate of active commuting to school. Daily moderate-to-vigorous physical activity, measured by accelerometers, was a secondary outcome. Child self-efficacy (alpha=0.75), parent self-efficacy (alpha=0.88), and parent outcome expectations (alpha=0.78) were independent variables. Participant characteristics (age, gender, race/ethnicity, distance from home to school, acculturation, and BMI percentile) were independent sociodemographic variables. We used mixed-model regression analyses to account for clustering by school and a stepwise procedure with backward elimination of non-significant interactions and covariates to identify significant moderators and predictors. School-level observations of student pedestrians were assessed and compared using chi-square tests of independence. Results: Among our sample, which was 61.7% Latino, the overall rate of active commuting to school was 43%. In the mixed model for active commuting to school, parent self-efficacy (std. beta = 0.18, p=0.018) and age (std. beta = 0.18, p=0.018) were positively related. Latino students had lower rates of active commuting to school than non-Latinos ( 16.5%, p=0.040). Distance from home to school was inversely related to active commuting to school (std. beta = 0.29, p<0.001). In the mixed model for moderate-to-vigorous physical activity, active commuting to school was positively associated (std. beta = 0.31, p <0.001). Among the Latino subsample, child acculturation was negatively associated with active commuting to school (std. beta = -0.23, p=0.01). With regard to school-level pedestrian safety observations, 37% of students stopped at the curb and 2.6% looked left-right-left before crossing the street. Conclusion: Although still below national goals, the rate of active commuting was relatively high, while the rate of some pedestrian safety behaviors was low among this low-income, ethnic minority population. Programs and policies to encourage safe active commuting to school are warranted and should consider the influence of parents, acculturation, and ethnicity.

Saturday Morning Television Advertisements Aired on English and Spanish Language Networks along the Texas-Mexico Border

Objectives: The aim of this content analysis study is to characterize the TV advertisements aired to an at-risk child population along the Texas-Mexico border. Methods: We characterized the early Saturday morning TV advertisements aired by three broadcast network categories (U.S. English language, U.S. Spanish language, and Mexican Spanish language) in Spring 2010. The number, type (food related vs. non-food related), target audience, and persuasion tactics used were recorded. Advertised foods, based on nutrition content, were categorized as meeting or not meeting current dietary guidelines. Results: Most commercials were non-food related (82.7%, 397 of 480). The majority of the prepared foods (e.g., cereals, snacks, and drinks) advertised did not meet the current U.S. Dietary Guidelines. Additionally, nutrition content information was not available for many of the foods advertised on the Mexican Spanish language broadcast network category. Conclusions: For U.S. children at risk for obesity along the Texas-Mexico border exposure to TV food advertisements may result in the continuation of sedentary behavior as well as an increased consumption of foods of poor nutritional quality. An international regulatory effort to monitor and enforce the reduction of child-oriented food advertising is needed. Editors' Note: This article was submitted in response to the first issue of the Journal of Applied Research on Children: Latino Children.

Use of cognitive interviewing in the development of a Spanish language genetic knowledge instrument

Study purpose. Genetic advances are significantly impacting healthcare, yet recent studies of ethnic group participation in genetic services demonstrate low utilization rates by Latinos. Limited genetic knowledge is a major barrier. The purpose of this study was to field test items in a Spanish-language instrument that will be used to measure genetic knowledge relevant to type 2 diabetes among members of the ethnically heterogeneous U.S. Latino community. Accurate genetic knowledge measurement can provide the foundation for interventions to enhance genetic service utilization. ^ Design. Three waves of cognitive interviews were conducted in Spanish to field test 44 instrument items Thirty-six Latinos, with 12 persons representative of Mexican, Central and South American, and Cuban heritage participated, including 7 males and 29 females between 22 and 60 years of age; 17 participants had 12 years or less of education. ^ Methods. Text narratives from transcriptions of audiotaped interviews were qualitatively analyzed using a coding strategy to indicate potential sources of response error. Through an iterative process of instrument refinement, codes that emerged from the data were used to guide item revisions at the conclusion of each phase; revised items were examined in subsequent interview waves. ^ Results. Inter-cultural and cross-cultural themes associated with difficulties in interpretation and grammatical structuring of items were identified; difficulties associated with comprehension reflected variations in educational level. Of the original 44 items, 32 were retained, 89% of which were revised. Six additional items reflective of cultural knowledge were constructed, resulting in a 38-item instrument. ^ Conclusions. Use of cognitive interviewing provided a valuable tool for detecting both potential sources of response error and cultural variations in these sources. Analysis of interview data guided successive instrument revisions leading to improved item interpretability and comprehension. Although testing in a larger sample will be essential to test validity and reliability, the outcome of field testing suggests initial content validity of a Spanish-language instrument to measure genetic knowledge relative to type 2 diabetes. ^ Keywords. Latinos, genetic knowledge, instrument development, cognitive interviewing ^

The effect of acculturation on diabetes prevalence in Hispanics: A systematic review

Context. The high prevalence of diabetes among Hispanics in the U.S. has stimulated increased interest in the role culture plays in Hispanics' risk of diabetes. It is critical to identify gaps in the existing research and to determine the relationship between acculturation and diabetes prevalence in the Hispanic population. ^ Objective. To review the current literature to evaluate the effects of acculturation on diabetes prevalence among Hispanic Americans. ^ Methods. A literature search of diabetes-related studies was conducted. Studies were selected for review if they reported at least one acculturation measure, used Hispanics adults (ages 18 and older) and included information regarding the diabetes prevalence of Hispanics and/or Latinos. Only those that examined acculturation by diabetes prevalence for Hispanics were included in the review. ^ Results. Sixteen studies were reviewed that met the search criteria and these studies used distinct measures of acculturation that captured four primary dimensions: time (duration of exposure to U.S. culture), language, culture and residence. Data represented studies conducted in a variety of settings, such as healthcare facilities in a state or region of the U.S. and nationally representative surveys. The data indicate positive, negative and no significant relationship with diabetes. Depending on the measure of acculturation used and gender the association between acculturation and diabetes varied. ^ Conclusions. There is no clear association between acculturation and diabetes prevalence; it can not be determined based on the available literature. Many of the studies examining this relationship found non-significant results and the directionality of the relationship varied greatly depending on the type of measure used, the number of measures used, and the study population. Ideal studies of acculturation should concentrate on investigating the links between time measures of acculturation, location of residence and changing beliefs, values and norms. A comprehensive acculturation scale is needed to better understand the complex relationship between diabetes prevalence amongst Hispanics and acculturation. ^

Latino perceptions of and barriers to preventive healthcare maintenance in the southwest United States

Between the 1990 and 2000 Censuses, the Latino population accounted for 40% of the increase in the nation’s total population. The growing population of Latinos underscores the importance for understanding factors that influence whether and how Latinos take care of their health. According to the U.S. Department of Human Health Service’s Office of Minority Health (OMH), Latinos are at greater risk for health disparities (2003). Factors such as lack of health insurance and access to preventive care play a major role in limiting Latino use of primary health care (Institute of Medicine, 2005). Other significant barriers to preventive health care maintenance behaviors have been identified in current literature such as primary care physician interaction, self-perceived health status, and socio-cultural beliefs and traditions (Rojas-Guyler, King, Montieth and 2008; Meir, Medina, and Ory, 2007; Black, 1999). Despite these studies, there remains less information regarding interpersonal perceptions, environmental dynamics and individual and cultural attitudes relevant to utilization of healthcare (Rojas-Guyler, King, Montieth and 2008; Aguirre-Molina, Molina and Zambrana, 2001). Understanding the perceptions of Latinos and the barriers to health care could directly affect healthcare delivery. Improved healthcare utilization among Latinos could reduce the long term health consequences of many preventable and manageable diseases. The purpose of this study was to explore Latino perceptions of U.S. health care and desired changes by Latinos in the U.S. healthcare system. The study had several objectives, including to explore perceived barriers to healthcare utilization and the resulting effects on health among Latinos, to describe culturally influenced attitudes about health care and use of health care services among Latinos, and to make recommendations for reducing disparities by improving healthcare and its utilization. The current study utilized data that were collected as part of a larger study to examine multidimensional, cross-cultural issues relevant to interactions between healthcare consumers and providers. Qualitative methods were used to analyze four Spanish-language focus group transcripts to interpret cultural influences on perceptions and beliefs among Latinos. Direct coding of transcript content was carried out by two reviewers, who conducted independent reviews of each transcript. Team members developed and refined thematic categories, positive and negative cases, and example text segments for each theme and sub-theme. Incongruities of interpretations were resolved through extensive discussion. Study participants included 44 self-identified Latino adults (16 male, 28 female) between age 18 and 64 years. Thirty seven (84.1%) of the participants were immigrants. The study population comprised eight ethnic subgroups. While 31% of the participants reported being employed on a full-time basis, only 18.4% had medical insurance that was private or employee sponsored. Five major themes regarding the perceptions and healthcare utilization behaviors of Latinos were consistent across all focus groups and were identified during the analysis. These were: (1) healthcare utilization, experience, and access; (2) organizational and institutional systems; (3) communication and interpersonal interactions between healthcare provider, staff, and patient; (4) Latinos’ perception of their own health status; (5) cultural influences on healthcare utilization, which included an innovation termed culturally-bound locus of control. Healthcare utilization was directly influenced by healthcare experience, access, current health status, and cultural factors and indirectly influenced by organizational systems. There was a strong interdependence among the main themes. The ability to communicate and interact effectively with healthcare providers and navigate healthcare systems (organizational and institutional access) significantly influenced the participant’s health care experience, most often (indirectly) impacting utilization negatively. ^ Research such as this can help to identify those perceptions and attitudes held by Latinos concerning utilization or underutilization of healthcare systems. These data suggest that for healthcare utilization to improve among Latinos, healthcare systems must create more culturally competent environments by providing better language services at the organizational level and more culturally sensitive providers at the interpersonal level. Better understanding of the complex interactions between these impediments can aid intervention developments, and help health providers and researchers in determining appropriate, adequate, and effective measurers of care to better increase overall health of Latinos.^

Social cognitive theory and factors associated with Mexican-American parents' beliefs, attitudes and practices regarding communication with their adolescent children about sex

Latinos have the highest teen birth rate nationally. Cameron County, Texas is primarily Latino (Mexican-American). This mixed-method study (n=43) examines Mexican-American parents of adolescents' beliefs, attitudes and practices regarding communication with their adolescent children about sex. Social Cognitive Theory (SCT) constructs self-efficacy, behavioral determinism, environment, outcome expectations and reciprocal determinism can be influences on frequency and quality of parent-adolescent sex communication.^ This study describes Mexican-American parents' of adolescents recollections of their own experiences associated with learning about sexuality. It also examines the attitudes and practices regarding communication about sex and the self-efficacy and behavioral capability of participants to teach their adolescent children about sex and sexually transmitted infections. ^ Negative childhood experiences (shame, lies and trauma) of the parents in this study played a key role in terms of their desire to communicate more comprehensively about sexuality with their own children than did their parents. While participants' reported low self-efficacy and behavioral capability to communicate with their adolescent children about sex, they reported relatively high frequency and quality of communication, with 75% of participants receiving a high quality score and over 44% reporting frequent communication with their adolescent children about sex. A Chi square analysis and Fisher's Exact Score revealed no association between acculturation status, gender or having a child who has mothered/fathered a baby and the frequency or quality of communication about sex with adolescent children. Study participants also gave specific recommendations for method, content and setting of sex education for their children and themselves. Promotora delivery of information and education in a comfortable, culturally appropriate neighborhood setting, as well as parent –child learning sessions were identified as possible approaches to address improve self-efficacy and behavioral capability of parents communicating with their adolescent children about sex.^ The results of this analysis provide public health practitioners and interested community entities data to identify and develop interventions that use a theoretical, evidence-based framework for culturally appropriate interventions to encourage and equip Mexican-American parents to effectively communicate with their adolescent children about sexuality, and ultimately to address the high rates of teen pregnancy in this U.S.-Mexico border community. ^

The role of social support in HIV prevention among young Latino men who have sex with men

The purpose of this formative study was to determine and prioritize the HIV-prevention needs of Latino young men who have sex with men (YMSM) in Chihuahua (Mexico), Texas, and California, based on YMSM and service provider perceptions of the factors affecting the assimilation and implementation of HIV-preventive behaviors. These factors included: perceived social support, identification of the modes of HIV transmission, perceived risk of HIV, perceived norms and attitudes of peers.^ The study, drawn from a secondary data set, was a convenience sample of providers (n=8) and clients (n=15). Participants completed face-to face interviews and a survey instrument. Interviews were analyzed to identify common themes and congruence among client groups, and among clients and providers. Providers’ understanding of theoretical constructs of interventions was also assessed. Survey data were analyzed to determine variable frequencies and their congruence to the qualitative analysis. ^ The results revealed several differences and many commonalities in the assimilation of protective messages. Client and provider perceptions were congruent across all domains. Providers demonstrated intuitive command of theoretical concepts but inconsistently verbalized their application. Both clients and providers recognized Latinos possessed high HIV-knowledge levels, despite inconsistent protective behaviors. Clients and providers consistently identified important reasons leading to inconsistent protective behaviors, such as: lack of access to targeted information and condoms, self-esteem, sexual identification, situational factors, decreased perceived HIV-risk, and concerns about homophobia, stigma, and rejection. Other factors included: poverty, failure to reach disenfranchised populations, and lack of role models/positive parental figures. The principal conclusion of the study was that there is a need for further study to understand the interrelationship between larger socioeconomic issues and consistent protective behaviors.^
