Leaf Functional Traits and Forest Structure of Tropical Dry Forest Species Along a Rainfall Gradient in Florida and Puerto Rico

This study examined how different rainfall regimes affect a set of leaf functional traits related to plant stress and forest structure in tropical dry forest (TDF) species on limestone substrate. One hundred fifty eight individuals of four tree species were sampled in six ecological sites in south Florida and Puerto Rico, ranging in mean annual rainfall from 858 to 1933 mm yr-1. Leaf nitrogen content, specific leaf area (SLA), and N:P ratio of evergreen species, but not deciduous species, responded positively to increasing rainfall. Phosphorus content was unaffected in both groups. Canopy height and basal area reached maxima of 10.3 m and 31.4 m2 ha-1, respectively, at 1168 mm annual rainfall. Leaf traits reflected soil properties only to a small extent. This led us to the conclusion that water is a major limiting factor in TDF and some species that comprise TDF ecosystems are limited by nitrogen in limestone sites with less than ~1012 mm rainfall, but organismal, biological and/or abiotic forces other than rainfall control forest structure in moister sites.

Life Experiences of Youth Who Were Born with HIV Infection in Puerto Rico: The Voices of Young Survivors

The effectiveness of antiretroviral therapy (ART) transformed the pediatric HIV epidemic. The disease changed significantly over the course of three decades: while early in the epidemic it was almost always fatal, it has become a chronic condition. This study examined how perinatally-infected youth experience the impact of HIV in their lives. A qualitative study using interpretative phenomenological analysis (IPA) was conducted. Twenty in-depth interviews were carried out among 12 women and 8 men aged 18 to 30 years in Puerto Rico. These were conducted in Spanish, audio-recorded, transcribed and translated into English. While narrating their experiences, participants were interpreting what the situation meant to them and how they make sense of it. Three topics emerged: (1) perception and response to treatment and illness, particularly their lived experiences with ART; (2) disclosure experiences; and (3) family matters. Most participants challenged their therapy, in most cases to force their caregivers to disclose their status. Problems with adherence were attributed to busy schedules or forgetfulness. Participants experienced the disfiguring adverse effects of ART, which they endured for years without being informed that ART was the cause of these. Participants’ experiences with disclosure demonstrated the importance of validating them as individuals capable of managing their health. The paternalistic approach of withholding their diagnosis to spare them suffering resulted in increased anxiety. Participants acknowledged the difficulties of revealing their HIV status to their partners. They referred to family and friends as essential in coping with HIV. However, some encountered discrimination and stigma within their families. Participants who had suffered the loss of their parents found other parental figures such as adoptive parents or other family members. Most participants expressed a desire to have children. Perinatally HIV-infected youth will require health services for the rest of their lives. The adult health care into which they transition should consider their needs and journey. Services should consider including family members. This study underscores the need for improved access to mental health services. It is also essential to transcend medical treatment and develop a broader perspective of health care. Health care services should include reproductive decision-making counselling services.

ANALYSIS OF GENDER RELATIONS IN THE INDUSTRIAL COMMUNITY OF AGUIRRE, PUERTO RICO

This thesis is a study of the gender relations of the residents of Aguirre, Puerto Rico, between 1940 and 1991. The primary goal of the project was to explore how gender roles and relations in the Aguirre community were impacted by the social class system introduced by the Aguirre Sugar Company. This project was based on the interpretation of the past and present situation of the Aguirre community using oral history, by conducting a series of interviews among its residents. The interviews resulted in three main themes. First, the concepts of `normal and natural' were used to distinguish gender roles. Second, Aguirreños identified `family as community', since through the family individuals built their gender identity and learned the basic rules of coexistence within the social hierarchy of the community. Third, although the gender and class roles were clear in the community, `resistance and negotiation' occurred in the home and at the Company between those of different gender and social classes. The Aguirre Sugar Company was one of the principal influences on the construction of the Aguirreños identity, and left a mark on the past, present and future generations.

Resistance performances: (Re)constructing spaces of resistance and contention in the 2010-2011 University of Puerto Rico student movement

On the night of April 20, 2010, a group of students from the University of Puerto Rico (UPR), Río Piedras campus, met to organize an indefinite strike that quickly broadened into a defense of accessible public higher education of excellence as a fundamental right and not a privilege. Although the history of student activism in the UPR can be traced back to the early 1900s, the 2010-2011 strike will be remembered for the student activists’ use of new media technologies as resources that rapidly prompted and aided the numerous protests. ^ This activist research entailed a critical ethnography and a critical discourse analysis (CDA) of traditional and alternative media coverage and treatment during the 2010 -2011 UPR student strike. I examined the use of the 2010-2011 UPR student activists’ resistance performances in constructing local, corporeal, and virtual spaces of resistance and contention during their movement. In particular, I analyzed the different tactics and strategies of resistance or repertoire of collective actions that student activists used (e.g. new media technologies) to frame their collective identities via alternative news media’s (re)presentation of the strike, while juxtaposing the university administration’s counter-resistance performances in counter-framing the student activists’ collective identity via traditional news media representations of the strike. I illustrated how both traditional and alternative media (re)presentations of student activism developed, maintained, and/or modified students activists’ collective identities. ^ As such, the UPR student activism’s success should not be measured by the sum of demands granted, but by the sense of community achieved and the establishment of networks that continue to create resistance and change. These networks add to the debate surrounding Internet activism and its impact on student activism. Ultimately, the results of this study highlight the important role student movements have had in challenging different types of government policies and raising awareness of the importance of an accessible public higher education of excellence.^

Perdurabilidad empresarial caso grupo empresarial Oikos S.A.

En Colombia se puede ver un alto número de creación de medianas y pequeñas empresas, pero un alto porcentaje de éstas no logran perdurar en el tiempo y cierran, mostrando así un grado significativo de morbilidad de las empresas colombianas. Según el Global Entrepreneurship Monitor – GEM , el 10,52% de las empresas que nacen en Colombia no son perdurables, por esta razón el estudio de la perdurabilidad de empresas del país ayuda a identificar cuáles son los componentes claves que han tenido durante sus años de vida y de igual forma cómo estos han ayudado a que perduren, logrando así ayudar a la correcta constitución de PYMES y a su vez se traduzca en la disminución de las tasas de desempleo que tiene el país. El Grupo de Investigación de Perdurabilidad de la Universidad del Rosario, ha identificado los siguientes trece componentes: Identidad Organizacional, Formalización para el Gobierno, Cohesión Social para la Acción, Reconocimiento por el Entorno y el Sector, diferenciación, Dinámica Social de los Empleados, Factores que aportan a la Eficiencia, Consolidación, Gestión Integral, Conocimiento de Entorno y Mercado, Eficiencia en Procesos y Gestión Financiera. Con la información recolectada y las encuestas realizadas, se obtuvo información de los empleados del Grupo Empresarial Oikos S.A., para determinar cuáles componentes se encontraban en la empresa y cuáles tenían mayor relevancia, corroborando de este modo si estos trece componentes contribuyen a la medición de la perdurabilidad empresarial.

Privacidad e intimidad en las interacciones virtuales

El presente trabajo es una revisión de la literatura de investigación en Ciberpsicología centrada en las categorías de privacidad, intimidad, identidad y vulnerabilidad, y en la forma como estas se desarrollan en las redes sociales virtuales. Los principales hallazgos indicaron que son los jóvenes quienes dedican gran parte de su tiempo a interactuar en dichas redes, y a su vez, dado el manejo que les dan, tienen mayor exposición ante los posibles riesgos de estas, como el matoneo, las conductas auto lesivas, la explotación sexual y los trastornos de la alimentación. Se describen estos riesgos y se proponen posibles soluciones.

Educación legal clínica y litigio estratégico en Iberoamérica.

Esta obra es resultado de investigación sobre dos conceptos de enorme importancia para la educación jurídica en Iberoamérica: la educación legal clínica como modelo pedagógico en construcción y el litigio estratégico como herramienta de incidencia social y política. Se considera que el proceso de construcción de las clínicas en la región es un hito en la educación jurídica iberoamericana y existen evidencias que permiten afirmarlo, ya que se trata de historias paralelas que se fortalecieron por los intercambios de aprendizajes y experiencias a través de las redes. De igual manera se desarrolla el concepto de litigio estratégico o estructural y se examina la forma como inciden en dicha propuesta las alianzas estratégicas. Se pasa luego a una profundización sobre la agenda de las clínicas y los temas prioritarios de Derechos Humanos en Iberoamérica. Examen que se realiza a partir de casos reales que se han trabajado las clínicas. Se concluye en la necesidad del surgimiento de nuevas clínicas y de más proyectos de investigación.

Geometría dinámica : una opción novel para la capacitación de maestros.

Resumen tomado de la publicación

Libros de texto y selección de vocabulario.

Se trata aquí de un proceso normal de enriquecimiento de conceptos en que los llamados sinónimos, que rara vez lo son , constituyen un aumento de matices que determinan el progresivo encuadramiento y dilatación del amplio y coherente mundo de la palabra. La reacción ante nuestro tema propuesto: vocabulario básico y pruebas de grado, seguido de una serie de valiosas contribuciones al tema desde distintos ángulos educativos, prueba claramente que la cuestión es de interés para todos los que, de una manera u otra, se preocupan de la enseñanza de idiomas. Hoy lo hemos orientado en el terreno más amplio que los que toquen el tema de los libros de texto, tengan en cuenta no un aspecto material y económico de la cuestión, sino el más fundamental de la adaptabilidad de los mismos a la edad mental del alumno. Recientemente, ha publicado la Universidad de Puerto Rico un tomo resultado del recuento de más de siete millones de palabras de distintas fuentes, que nos muestra cuales son las palabras más frecuentes del español hablado en la isla y un utilísimo recuento de formas flexionadas, verbos y nombres, de enorme interés para el conocimiento de la morfología del español usado allí. En él quedan de relieve y fundadas estadísticamente diversas peculiaridades lingüísticas ya apuntadas en estudios precedentes. Hoy cuando van cobrando importancia y actualidad los métodos estadísticos en la lingüística, este tipo de estudios nos trae un aire de modernidad que hay que valorar debidamente. No hay duda de que con interés mucho se puede hacer en la selección en el vocabulario para que nuestros libros escolares sean más atractivos y más eficaces.
