Body image and femininity of Latina breast cancer survivors

El cáncer del seno es el cáncer más común entre mujeres latinas que viven en los Estados Unidos. Todavía queda mucho que aprender sobre el impacto del cáncer del seno en Latinas. Investigaciones sobre sobrevivientes del cáncer del seno se han enfocado en la experiencia de mujeres recientemente diagnósticadas que han sobrevivido hasta cinco años desde el diagnóstico. Está menos estudiado el caso de las Latinas sobrevivientes del cáncer del seno a largo plazo (mas de cinco años). Este estudio pretende a contribuir a las investigaciones de percepciónes sobre su cuerpo y su femenidad de sobrevivientes Latinas del cáncer del seno. Usando metodología cualitativa, 25 Latinas que son sobrevivientes de cáncer del seno cinco años o más entre las edades de 28 y 83, específicamente las de origen Mexicano residiendo en California, fueron entrevistadas sobre sus experiencias sobre cáncer del seno. Los resultados mostraron que la percepción de las Latinas sobre su cuerpo, femenidad y bienestar es socialmente contruida

The impact of immigration-related challenges and deportation worries on the well-being of latinos in the U.S.

Increased public awareness of immigration issues creates challenges for Latinos and the deportation of undocumented immigrants in record numbers is a source of worry in the Latino community in the U.S. Very few studies have examined how the preceding factors impact the lives and outlook of Latinos-specifically their quality of life, their confidence in the future, and their situation in the U.S. Using large nationally representative data, it was found that the challenges posed by increased public awareness of immigration issues and the worries associated with immigration indeed negatively affected the lives and outlook of Latinos. It was found that challenges and worries had independent and additive effects on the dependent variables. Further, deportation worries affected quality of life and/or situation in the U.S. for Latinos who were citizens and non-citizens.La deportación de inmigrantes indocumentados en cantidades récord es una fuente de preocupación en la comunidad Latina en los Estados Unidos. Además, el aumento de la concienciación de los ciudadanos sobre las cuestiones de inmigración crea retos para los latinos. Muy pocos estudios han examinado cómo estos factores afectan las vidas y perspectivas de los latinos, concretamente su calidad de vida, su confianza en el futuro y su situación en los Estados Unidos. El análisis de la Encuesta Nacional de Latinos 2007 realizada por el Pew Hispanic Center indicó que los desafíos resultantes de una mayor conciencia pública sobre las cuestiones de inmigración y las preocupaciones asociadas de la inmigración en realidad afectó negativamente a las vidas y perspectivas de los latinos. El análisis demostró que los retos y preocupaciones tenían efectos independientes y aditivos sobre las variables dependientes. Además, la preocupación sobre la deportación afecta a la calidad de vida y a la situación de los latinos ciudadanos y no ciudadanos de los Estados Unidos

Products of finite connected subgroups

For a non-empty class of groups L, a finite group G = AB is said to be an L-connected product of the subgroups A and B if e L for all a e A and b e B. In a previous paper, we prove that, for such a product, when L = S is the class of finite soluble groups, then [A, B] is soluble. This generalizes the theorem of Thompson that states the solubility of finite groups whose two-generated subgroups are soluble. In the present paper, our result is applied to extend to finite groups previous research about finite groups in the soluble universe. In particular, we characterize connected products for relevant classes of groups, among others, the class of metanilpotent groups and the class of groups with nilpotent derived subgroup. Additionally, we give local descriptions of relevant subgroups of finite groups

Study on the vibration characteristics of the telescope T80 in the Javalambre astrophysical observatory (JAO) aimed at detecting invalid images

The location of large telescopes, generally far from the data processing centers, represents a logistical problem for the supervision of the capture of images. In this work, we carried out a preliminary study of the vibration signature of the T80 telescope at the Javalambre Astrophysical Observatory (JAO). The study analyzed the process of calculating the displacement that occurs because of the vibration in each of the frequencies in the range of interest. We analyzed the problems associated with very low frequencies by means of simulation, finding the most critical vibrations below 20 Hz, since they are the ones that generate greater displacements. The work also relates previous studies based on simulation with the real measurements of the vibration of the telescope taken remotely when it is subjected to different positioning movements (right ascension and/or declination) or when it performs movement actions such as those related to filter trays or mirror cover. The obtained results allow us to design a remote alarm system to detect invalid images (taken with excess vibration)

Modified filtered-x hierarchical lms algorithm with sequential partial updates for active noise control

In the field of active noise control (ANC), a popular method is the modified filtered-x LMS algorithm. However, it has two drawbacks: Its computational complexity higher than that of the conventional FxLMS, and its convergence rate that could still be improved. Therefore, we propose an adaptive strategy which aims at speeding up the convergence rate of an ANC system dealing with periodic disturbances. This algorithm consists in combining the organization of the filter weights in a hierarchy of subfilters of shorter length and their sequential partial updates (PU). Our contribution is threefold: (1) we provide the theoretical basis of the existence of a frequency-depend-ent parameter, called gain in step-size. (2) The theoretical upper bound of the step-size is compared with the limit obtained from simulations. (3) Additional experiments show that this strategy results in a fast algorithm with a computational complexity close to that of the conventional FxLMS

Products of finite connected subgroups

For a non-empty class of groups $\cal L$, a finite group $G = AB$ is said to be an $\cal L$-connected product of the subgroups $A$ and $B$ if $\langle a, b\rangle \in \cal L$ for all $a \in A$ and $b \in B$. In a previous paper, we prove that for such a product, when $\cal L = \cal S$ is the class of finite soluble groups, then $[A,B]$ is soluble. This generalizes the theorem of Thompson which states the solubility of finite groups whose two-generated subgroups are soluble. In the present paper our result is applied to extend to finite groups previous research in the soluble universe. In particular, we characterize connected products for relevant classes of groups; among others the class of metanilpotent groups and the class of groups with nilpotent derived subgroup. Also we give local descriptions of relevant subgroups of finite groups
