Familias Sanas: an Intervention Designed to Increase rates of Postpartum Visits among Latinas  

PubMed Central

Familias Sanas (Healthy Families) is an educational intervention implemented and tested with low-income, immigrant Latina mothers. The program was designed to reduce existing health disadvantages of Latinas by empowering them to take active part in the management of their health and by encouraging them to advocate for themselves. Familias Sanas was implemented at a prenatal clinic located at a major urban hospital in the southwestern U.S. The efficacy of the intervention was evaluated through a randomized control trial measuring the participants’ rate of postpartum visits and other relevant well-being measures. Initial findings show a significant effect of the intervention, with participants in the experimental group returning for their postpartum clinic visit at a higher rate in comparison with the control group. The results are discussed from a culturally specific perspective. Practice, policy, and research implications and recommendations are provided.

Factores predictores de inicio y cesaci?n de tabaquismo en una cohorte de mujeres chilenas con 5,5 a?os de seguimiento  

PubMed Central

Background Chilean women have one of the highest smoking prevalence in the world. Aim To estimate the main factors associated with smoking initiation and quitting among a cohort of adult women living in a low socioeconomic status area of Santiago, Chile. Material and methods A random population-based sample of 1,100 women, 18 years and older, were selected from a community located in the South East area of Santiago. Sociodemographic, as well as smoking, beliefs, behaviors, stages of change and nicotine addiction level were recorded during a personal interview. After an average follow-up period of 5.5 years, women were re-evaluated. Results Seventy-three percent of women completed the study. At baseline, 39% of women were smokers. At the end of the study, there was an absolute smoking rate reduction of 7.1% (p<0.001). The main variables associated with smoking initiation were younger age (Odds ratio (OR): 1.08, 95% confidence intervals (CI): 1.05–1.12), higher education level (OR: 1.2, 95% CI: 1.07–1.35), and having fewer children (OR: 1.3 95% CI: 1.01–1.66). Factors related with quitting were younger age of onset (OR: 1.06 95% CI: 1.02–1.1), higher level of nicotine dependence (OR: 4.22, 95% CI: 1.74–10.27), and higher perception of smoking addiction (OR: 4.34, 95% CI: 2–9.09). Stage of change was associated with smoking cessation but its effect was diluted after adjusting for the level of nicotine addiction. Conclusions Sociodemographic and family factors were the main variables related with initiation, whereas age of onset, belief of addiction, and nicotine dependence were the main factors related with cessation. Women with a high motivation for quitting should be evaluated for nicotine addiction level to define the best strategy for intervention (Rev Méd Chile 2009; 137: 1001–9).

Nutrient adequacy and diet quality in non-overweight and overweight Hispanic children of low socioeconomic status - the VIVA LA FAMILIA Study  

PubMed Central

Objective The role of diet quality and nutrient adequacy in the etiology of childhood obesity is poorly understood. The specific aims of these analyses were to 1) assess overall diet quality and nutrient adequacy, and 2) test for association between weight status and diet in children from low socioeconomic status (SES) Hispanic families at high risk for obesity. Design A cross-sectional study design was used to assess dietary intake in low-SES non-overweight and overweight Hispanic children enrolled in the VIVA LA FAMILIA Study. Multiple-pass 24-h dietary recalls were recorded on two random, weekday occasions. Diet quality was evaluated according to United States (US) Dietary Guidelines. Nutrient adequacy was assessed using z-scores based on estimated average requirement (EAR) or adequate intake (AI). Subjects/Setting The study included 1030 Hispanic children and adolescents, ages 4-19 y, in Houston, Texas who participated between November 2000 and August 2004. Statistical analysis STATA was used for generalized estimating equations and random effects regression. Results Diet quality did not adhere to US dietary guidelines for fat, cholesterol, saturated fatty acids, fiber, added sugar and sodium. Although energy intake was significantly higher in overweight children, food sources, diet quality, macro- and micronutrient composition were similar between non-overweight and overweight children. Relative to EAR or AI, mean nutrient intakes were adequate (70-98% probability) in the non-overweight and overweight children, except for vitamins D and E, pantothenic acid, calcium and potassium for which z-scores cannot be interpreted given the uncertainty of their AI's. Conclusion While the diets of low-SES, non-overweight and overweight Hispanic children were adequate in most essential nutrients, other components of a healthy diet, which promote long-term health, were suboptimal. Knowledge of the diet of high risk Hispanic children will inform nutritional interventions and policy.

Observaciones del disco solar y de una protuberancia quiescente en radiación ultravioleta  

NASA Astrophysics Data System (ADS)

Observaciones del disco solar y de una protuberancia quiescente en el rango de longitudes de onda ultravioleta fueron obtenidas con el instrumento CDS (Coronal Diagnostic Spectrograph) y SUMER (Solar Ultraviolet Measurements of emitted radiation) a bordo de la sonda SOHO. El propósito es investigar las velocidades macroscópicas de varias especies metálicas que se observan tanto en el disco solar como en el plasma de las protuberancias. Para calcular las velocidades del disco solar aplicamos una técnica mixta para modelar la distribución de estructuras en UV en el Sol quieto. Las velocidades macroscópicas en las protuberancias se calcularon a partir de los corrimientos Doppler en cada línea espectral y luego se tomaron las del disco solar como referencia. Obtuvimos valores absolutos para las velocidades macroscópicas entre 5 y 40 km/seg. También detectamos comportamientos diferentes en las velocidades de las protuberancias en el centro con respecto a los bordes.

Heterochromatin heterogeneity in Hypostomus prope unae (Steindachner, 1878) (Siluriformes, Loricariidae)from Northeastern Brazil  

PubMed Central

Abstract Cytogenetic analyses using C-banding and chromosomal digestion by several restriction enzymes were carried out in four populations (named A, B, C and D) of Hypostomus prope unae (Loricariidae, Hypostominae) from Contas river basin, northeastern Brazil. These populations share 2n=76 and single NORs on the second metacentric pair but exclusive karyotype forms for each locality. Populations A and B presented conspicuous terminal and interstitial heterochromatic blocks on most of acrocentric chromosomes and equivalent to NORs with differences in both position and bearing pair. Population D showed evident marks at interstitial regions and interspersed with nucleolar region while population C presented interstitial and terminal heterochromatin segments, non-coincident with NORs. The banding pattern after digestion with the endonucleases Alu I, Bam HI, Hae III and Dde I revealed a remarkable heterogeneity within heterochromatin, allowing the identification of distinctive clusters of repeated DNA in the studied populations, besides specific patterns along euchromatic regions. The analysis using restriction enzymes has proved to be highly informative, characterizing population differences and peculiarities in the genome organization of Hypostomus prope unae.

[Il ruolo del cervelletto nella depressione unipolare e bipolare: una rassegna delle principali evidenze neurobiologiche].  

PubMed

riassunto. Evidenze derivanti da numerosi studi condotti sia su pazienti affetti da patologie cerebellari sia su soggetti sani suggeriscono che il cervelletto eserciti, oltre a un ruolo ormai ben definito nel controllo e nella regolazione delle funzioni motorie, una significativa attività di modulatore del tono dell'umore, del comportamento e delle funzioni cognitive. In questo lavoro di revisione abbiamo passato in rassegna tutti quegli studi di neuroimaging volti a indagare la presenza di alterazioni cerebellari sia morfologiche sia funzionali in pazienti affetti da disturbo bipolare (DB) e disturbo depressivo maggiore (DDM), ipotizzando l'esistenza di un meccanismo fisiopatologico alla base di questi disturbi, che coinvolga, almeno in parte, il cervelletto. Allo stesso scopo, sono stati esaminati anche quegli studi post mortem che indagavano la presenza di alterazioni cellulari e molecolari a partire da campioni di tessuto cerebellare, per esempio alterazioni delle proteine mitocondriali, della tirosin-chinasi B e del brain-derived neurotrophic factor (BDNF), del fattore di trascrizione SP4, della proteina fibrillare acida della glia (GFAP). In totale sono stati esaminati 28 studi, 12 inerenti le alterazioni morfologiche e funzionali del cervelletto nel DB, 13 inerenti le alterazioni morfologiche e funzionali del cervelletto nel DDM e 4 inerenti le alterazioni cerebellari post mortem in entrambi i disturbi. Dal nostro lavoro di revisione, in linea con quanto presente nella letteratura internazionale, emerge l'interessante ipotesi che il cervelletto funzioni come un "pacemaker emotivo" e che quindi una sua lesione potrebbe tradursi nell'incapacità dell'individuo di rimanere in equilibrio sulla sottile linea dell'eutimia, giustificando in questo modo la comparsa di profonde oscillazioni emotive sia sul versante depressivo sia su quello maniacale.

Most of the asteroids families are a consequense of a high speed colission between one of those bodies against a smaller one. In an attemp to understand the distribution of sizes, rotational velocities, shapes and other characteristics of the fragments, we are carrying out studies and numerical simulations. Particularly, our work is oriented to study the distribution of rotational periods and sizes of asteroids members of diverses families, specially Maria and Themis. In this sense, photometric observations in order to calculate their sizes and rotational periods are realized. Moreover, we are working on a collisional model that relates the observed rotational periods of the fragments with that one of the original body. In this work we present the results of the observations carried out with the 1.54 reflector of the Bosque Alegre Astrophysical Station.

Electrochemistry and in situ scanning tunnelling microscopy of pure and redox-marked DNA- and UNA-based oligonucleotides on Au(111)-electrode surfaces.  

PubMed

We have studied adsorption and electrochemical electron transfer of several 13- and 15-base DNA and UNA (unlocked nucleic acids) oligonucleotides (ONs) linked to Au(111)-electrode surfaces via a 5'-C6-SH group using cyclic voltammetry (CV) and scanning tunnelling microscopy in aqueous buffer under electrochemical potential control (in situ STM). 2,2',6',2''-Terpyridine (terpy) onto which the transition metal ions Fe(2+/3+), Os(2+/3+) and Ru(2+/3+) could be coordinated after UNA monolayer formation was attached to UNA via a flexible linker. The metal centres offer CV probes and in situ STM contrast markers, and the flexible UNA/linker a potential binder for intercalation. CV of pure and mercaptohexanol diluted ON monolayers displayed reductive desorption signals but also, presumably capacitive, signals at higher potentials. Distinct voltammetric signals arise on metal binding. Those from Ru-binding are by far the strongest and in accord with multiple site Ru-attachment. In situ STM disclosed molecular scale features in varying coverage on addition of the metal ions. The Ru-derivatives showed a bias voltage dependent broad maximum in the tunnelling current-overpotential correlation which could be correlated with theoretical frames for condensed matter conductivity of redox molecules. Together the data suggest that Ru-units are bound to both terpy and the UNA-DNA backbone. PMID:23073185

Lipozyme(®) TL IM (Theremomyces lanuginosus lipase immobilized on silica) in toluene catalyzes the acylation of the 2'-OH over the 3'-OH group in 5'-O-(4,4'-dimethoxytrityl)-2',3'-secouridine (5'-O-DMT-2',3'-secouridine) in a highly selective fashion in moderate to almost quantitative yields. The turn over during benzoyl transfer reactions mediated by vinyl benzoate or benzoic anhydride was faster than in acyl transfer reactions with vinyl acetate or C(1) to C(5) acid anhydrides; except in the case of butanoic anhydride. The 2'-O-benzoyl-5'-O-DMT-2',3'-secouridine obtained by Lipozyme(®) TL IM catalyzed benzoylation of 5'-O-DMT-2',3'-secouridine was successfully converted into its 3'-O-phosphoramidite derivative in satisfactory yield, which is a building block for the preparation of oligonucleotides containing the uracil monomer of UNA (unlocked nucleic acid).

Review of antiviral and immunomodulating properties of plants of the Peruvian rainforest with a particular emphasis on Una de Gato and Sangre de Grado.  

PubMed

Viral diseases, including emerging and chronic viruses, are an increasing worldwide health concern. As a consequence, the discovery of new antiviral agents from plants has assumed more urgency than in the past. A number of native Amazonian medicines of plant origin are known to have antimicrobial and anti-inflammatory activity, although only a few have been studied for their antiviral properties and immunomodulating effects. Those most studied include: Sangre de Grado (drago) (Croton lechleri) in the Euphorbiaceae family and Una de Gato (Uncaria tomentosa) in the Rubiaceae family. This article reviews the chemical composition, pharmacological properties, state of current research, clinical use, and potential antiviral and immunomodulating activity of these and other plants from the Peruvian Amazon.

Filling the gap in LNA antisense oligo gapmers: the effects of unlocked nucleic acid (UNA) and 4'-C-hydroxymethyl-DNA modifications on RNase H recruitment and efficacy of an LNA gapmer.  

PubMed

Stability against nucleases, affinity for the targeted mRNA and the ability to recruit RNase H are prerequisites for antisense oligonucleotide (AON) applications where gene expression knockdown is required. Typically chimeric gapmer AON designs are used with a central continuous stretch of RNase H recruiting nucleotides (e.g. phosphorothioate DNA), flanked by affinity and stability-enhancing modified nucleotides. However, many types of nucleotide modifications in the central DNA gap can disturb RNase H function. Here we present studies into two different types of nucleotide modifications, a flexible acyclic RNA analog named unlocked nucleic acid (UNA) and 4'-C-hydroxymethyl-DNA in the gap of an LNA (locked nucleic acid) flanked gapmer. We compared the efficacy of mRNA degradation by the gap modified LNA antisense gapmers in cell-free assays and cultured cells. This study shows that both UNA and 4'-C-hydroxymethyl-DNA gap insertions are compatible with RNase H activity when used sparingly. However, multiple 4'-C-hydroxymethyl-DNA modifications are better tolerated by RNase H than multiple UNA modifications in the gap. Furthermore, this report shows that LNA gapmer AONs with multiple 4'-C-hydroxymethyl-DNA moieties in the gap can mediate target knockdown in vivo. PMID:19603119

Revision curricular a partir de un analisis comparativo de las discrepancias en los curriculos de una escuela de optometria en Puerto Rico con las competencias requeridas para las agencias de revalida y acreditacion 2004  

NASA Astrophysics Data System (ADS)

El proposito de esta investigacion, un estudio cualitativo de caso, fue comparar y contrastar el curriculo vigente de la Escuela de Optometria de la UIAPR con las competencias y estandares requeridos por las agencias de acreditacion y de revalida. Con este proposito, decidimos realizar una revision y un analisis de documentos: el prontuario de cada uno de los cursos de los curriculos implantados en el 1993 y en el 2001; las competencias y estandares establecidos por las agencias de revalida y de acreditacion; y las estadisticas en las que se analiza el porcentaje de estudiantes que aprueban cada una de las partes de los examenes de revalida entre el 1998 al 2003. Se realizaron entrevistas dirigidas para dar apoyo y complementar la revision y el analisis de estos documentos. Los participantes de las entrevistas fueron tres estudiantes de la clase de optometria del 2004 (ultima clase del curriculo del 1993); tres estudiantes de la clase de optometria del 2005 (primera clase graduanda del curriculo vigente) y tres profesores y/o directores de los Departamentos de Ciencias Basicas, Ciencias Clinicas y Cuidado al Paciente. Esta investigacion se enmarco en el modelo de evaluacion curricular de discrepancia de Malcolm Provus y en el modelo de desarrollo basado en competencias. Uno de los hallazgos mas importantes del estudio es que los cambios que se implantaron al curriculo del 2001 no han logrado que los estudiantes mejoren su ejecucion en los examenes de revalida. Por otro lado, se encontro que el curriculo vigente atiende completamente los estandares de la practica de Optometria, pero no las competencias. Esta informacion fue validada mediante el uso de una tabla de cotejo para el analisis de los cursos y de la informacion obtenida de las entrevistas. El estudio determina y concluye que existen discrepancias entre los prontuarios de los cursos del curriculo y las competencias requeridas por la agencia de revalida. Segundo, que el Departamento de Ciencias Basicas es el que presenta mas deficiencias en el desarrollo de las competencias. El investigador recomienda disenar e implantar un curriculo basado en competencias y proveer formacion en didactica y procesos de aprendizaje a los profesores.

La Familia: methodological issues in the assessment of perinatal social support for Mexicanas living in the United States.  

PubMed

Do Mexicanas receive social support from a close network of family and friends during the perinatal period? To answer this question, a longitudinal ethnographic study followed 28 urban Mexican-origin women living in the US from their last trimester of pregnancy through their first month post-partum. A total of 93 interviews with Mexicanas focused on health and social support. All of the women lived in a large western city in the US but varied in their acculturation and income levels. Analyses identified four social support themes from women's experience (the emic analysis) and four social support typologies from the researcher (etic) analyses. The kinds of support women described as emanating from their support networks were inductively identified as Helping with Daily Hassles, Showing Love and Understanding, Being There for Me, and My Family Failing Me. Approximately half of the women reported densely supportive networks. The other women were disconnected from their support networks, or dealt with antagonism or instability in their networks. Women's perceptions of social support differed from the judgements made by the researcher about received support. Specifically, women perceived more network members in the supportive category than did the researcher by a factor of 1.4, and fewer network members in the disconnected category by a factor of 0.7. From an emic perspective, women listed only half as many antagonistic network members compared to the etic analysis (a factor of 0.50). These emic/etic discrepancies complicate clinical assessment of social support, but suggest that data on social support should be collected as part of the clinical processes of perinatal risking. To enhance assessment of social support, a clinically relevant guide is proposed for use by practitioners caring for Mexicanas in the perinatal period. PMID:11676402

Evaluacion de proceso del programa de educacion afectivo-sexual Ni ogros ni princesas.  

PubMed

RESUMEN Fundamento: En 2008, se puso en marcha el programa Ni ogros ni princesas en 12 centros de secundaria de Asturias (España) para incorporar la educación afectivo-sexual. El programa proponía 14 actividades, dirigidas a alumnado, profesorado y familias. Este estudio recoge la evaluación de proceso de esta intervención, en relación a la ejecución de las actividades, participación, satisfacción, utilidad percibida y propuestas de mejora. Métodos: La población de estudio fueron los 12 centros que participaron en el programa, y su alumnado, profesorado y familias. Se obtuvo información sobre la ejecución de actividades mediante un cuestionario de seguimiento; se recogió la satisfacción y utilidad percibida con cuestionarios auto-administrados para alumnado y profesorado; también se recogieron sus propuestas de mejora, y las de las familias, en grupos focales. Resultados: El número medio de actividades realizadas por los 12 centros fue 11,6. Se implicaron 185 docentes (26%), que impartieron sesiones al 81% del alumnado en estos 12 centros. El número medio de sesiones impartidas fue 6 en cada nivel de la ESO. El 79% del profesorado se sintió bastante/muy satisfecho con su actuación y al 65% del alumnado le gustaron bastante/mucho estas sesiones. Más del 60% de estudiantes y docentes consideraron que estas sesiones servían bastante/mucho para aumentar conocimientos, reflexionar, mejorar la igualdad, conocer otras opiniones y favorecer el respeto a la diversidad sexual. Entre las propuestas de mejora, más horas para la educación sexual, liberación horaria para el profesorado, y más actividades para familias. Conclusiones: El programa fue una intervención novedosa y percibida como útil para incorporar la educación sexual en los centros de secundaria, ya que contó con un gran nivel de ejecución, así como una alta participación, satisfacción y utilidad percibida por el alumnado y profesorado.

Movimiento regular y caótico en cúmulos globulares

Los cúmulos globulares exhiben diferentes grados de elipticidad y se mueven en el campo gravitatorio de la galaxia a la que pertenecen. Las órbitas de sus estrellas no necesitan, por ello, conservar la energía ni el momento angular, y resulta probable la presencia de movimientos caóticos. Como paso preliminar de una investigación más extensa, presentamos aquí los resultados de un estudio de órbitas estelares en un cúmulo globular levemente triaxial que describe una órbita circular dentro de una galaxia. Las órbitas se investigan utilizando dos métodos: 1) La clasificación por frecuencias de D.D. Carpintero y L.A. Aguilar (1998, MNRAS, en prensa), y 2) Los exponentes de Lyapunov (subrutina LIAMAG, gentilmente suministrada por D. Pfenniger). Utilizando diversos espacios de condiciones iniciales, investigamos las familias de órbitas de las estrellas del cúmulo. Confirmamos la presencia de órbitas caóticas, particularmente en las zonas externas del cúmulo, y discutimos su importancia para la estructura del cúmulo.

This means that the pathway regulation is integrated to the whole plant metabolism. Starch degradation is a

Fixed a profile of pulsating luminosity and for a previously studied state equation, it can be demostrated that the frequency of the profile coincides with the frequency of oscillation of the star`s surface. It is proven also that the collapse of a strange star is slower a hundred times that the corresponding to a star of normal matter.

C/1999 S4 (LINEAR): la morte di una cometa  

NASA Astrophysics Data System (ADS)

The comet C/1999 S4 was expected to be a moderately bright object during summer 2000. It was observed by visual, photographic and CCD techniques. The derived light curve shows that the comet reached a brightness maximum (mag. 6 around July 26) corresponding to the total dissolution of its nucleus. From the analysis of the light curve a double maximum was detected, the dissolution event appearing to start around July 20. Several morphological changes were also observed during the apparition in relation to partial fragmentation events. The comet aspect completely changed during the final disruption. Relevant changes in the plasma tail were observed and they are probably related both to the activity of the nucleus and to the solar wind. A perspective anti-tail was detected in early July.

Comunicaci?n de pareja y VIH en mujeres en desventaja social  

PubMed Central

Introducción La epidemia de VIH y SIDA se ha diseminado rápidamente a nivel mundial tendiendo a la feminización, pauperización y heterosexualización. La comunicación de pareja en torno el VIH es descrita como uno de los factores protectores en la adquisición de esta enfermedad, favoreciendo la adopción de conductas sexuales seguras tales como la negociación de pareja y la utilización de preservativo, consideróndose como un pilar fundamental en la incorporación de medidas de autocuidado en la sexualidad femenina. Objetivo Determinar el nivel de comunicación de pareja en torno al VIH en mujeres chilenas en desventaja social. Metodología Cuatrocientas noventa y seis mujeres contestaron la entrevista inicial de la investigación “Testing an HIV/AIDS Prevention Intervention for Chilean Women” (RO1 TW 006977 PI Cianelli). Se utilizó la escala “Health protective sexual communication scale (HPC)” (0–10 puntos). Se realizó un análisis descriptivo utilizando el programa SPSS 16.0. Resultados El promedio del nivel de comunicación de pareja fue de 3,26 ± 2,7 puntos con la pareja principal, de 2,52 ± 2,48 puntos con una segunda pareja y de 0 puntos con una tercera pareja. Los temas de menor comunicación entre las parejas fueron el uso de preservativo y la realización del test para VIH antes de tener relaciones sexuales. Conclusión Las mujeres de la muestra presentan bajos niveles de comunicación de pareja en relación a VIH con todas sus parejas sexuales. Son necesarias estrategias que potencien este tópico dentro de las intervenciones de prevención de VIH y SIDA de manera de fortalecer la adopción de conductas de autocuidado en torno al tema.

Displacing the video camera from the perfect focus, a disk or an annulus of light is recorded with a refractor or a reflector, respectively, only if it is the image of a real lunar flash. Inserting a spectroscope between the telescope objective and the video camera the spectrum of the flash light is recorded which may give useful informations about the chemistry and the physics of the event. Spurious flashes, normally due to cosmic rays or to camera noise, do not change their aspect in out of focus images nor in the dispersed ray beam.

Promoviendo una Alimentaci?n Saludable (PAS) Design and Methods: Engaging Latino Families in Eating Disorder Treatment  

PubMed Central

The use of culturally sensitive intervention could improve mental health care for the eating disorders treatment in the Latino population. The aim of this report is to describe the rationale, design, and methods of the ongoing study entitled “Engaging Latino families in eating disorders treatment.” The primary aim of the study is to compare (a) the combined effect of individual cognitive behavioral therapy for bulimia nervosa (CBT-BN) that has been previously adapted for the Latino population plus Family Enhanced (FE) modules, with (b) the standard adapted individual CBT-BN in a proof-of-principle study with 40 Latina adults with eating disorders and one relative or significant other per patient. We hypothesize that 1) the feasibility, acceptability, and adherence of participants in CBT-BN+ FE will be superior to individual CBT-BN only; 2) relatives in CBT-BN+ FE will report greater treatment satisfaction, greater reduction in family conflict, and greater decreases in caregiver burden than relatives in the individual CBT-BN only condition; and 3) patients who participate in CBT-BN+ FE will show trends towards greater decreases in ED symptoms compared with patients in CBT-BN only; although power will be limited to detect this difference. However, we predict that they will show greater retention in treatment, greater treatment satisfaction, and greater decreases in family conflict than patients in CBT-BN only. The completion of this investigation will yield important information regarding the acceptability and feasibility of a culturally sensitive evidence-based treatment model for Latinos with eating disorders.

Gli indici di colore come indicatori del meccanismo che governa la luminosità di una cometa: luce solare riflessa o fluorescenza  

NASA Astrophysics Data System (ADS)

Colour indexes derived by aperture photometry on cometary comae in VRI Johnson/Cousins bands give a way to understand the mechanism dominating the brightness of a comet: reflected sunlight or fluorescence. Considering that V band is dominated by C2 gas emission and that R and I on the contrary have few gas contamination, the colour index determined as a function of the coma diameter is a key parameter. In an hypothetical purely dusty coma we expect a constant colour index close to the solar one and nearly constant with aperture. If gas is present we can have a differentiation within the coma and a non constant colour index, in this case the colour index is "bluer" in the external halo. The effect was clearly observed in C/2001 A2 and C/2000 WM1.

Desarrollo de una Interfaz de Control para un Observatorio Astronómico Robotizado con fines educativos en la Facultad de Ciencias Exactas; Físicas y Naturales de la UNSJ  

NASA Astrophysics Data System (ADS)

We report the development and the construction of an Interface to Control a robotized Astronomical Observatory (ICOA), which allows to control the operation of an observatory based on a Meade LX200 telescope. The interface operates together with a computer to control and supervise all the local variables of the observatory, and can take the control of it in risky situations. It serves as a link among the control computer and all the necessary devices for the astronomical observation such as the telescope, the dome, the weather station, the CCD camera, the calibration devices and the security devices. The computer receives orders from an operator who can be or not at the site of observation. The goal of this robotized observatory is the operation in a secure, autonomous and unattended way, with the purpose of to be used remotely by the students of the "Facultad de Ciencias Exactas, Físicas y Naturales" of the UNSJ.

Consequences of antenna design in telemetry studies of small passerines [Consecuencias en el disen??o de una antena en un estudio de radiotelemetria para paserinos  

USGS Publications Warehouse

Entanglement and mortality of Palila (Loxioides bailleui), an endangered Hawaiian honeycreeper, occurred when birds were radio-tagged with transmitters equipped with a long, limp, solder-tipped antenna. Birds were found suspended in trees by their transmitter antenna on eight occasions. Although these birds eventually freed themselves or were freed by us, at least one bird died afterwards. For radio telemetry studies of small passerine species we recommend avoiding transmitters equipped with an antenna that is bulbous at the tip, >16 cm in length, limp, and shiny.

Terrestrial and airborne laser scanner techniques applied to rock slope instability analysis: the case of Einser-Cima Una (Sexten Dolomites, Italy)  

NASA Astrophysics Data System (ADS)

A representative characterization of a rock instability phenomenon is a fundamental task in the understanding of its evolution and the forecasting of possible further slope failure. The first step towards a complete study of the unstable slope consists in its detailed geometrical, geomechanical and kinematical characterization in order to generate a high resolution 3D digital model of the investigated area, recognize the main discontinuity sets of the rock mass, evaluate displacements and deformations occurred between subsequent surveys. This kind of study can be carried out by means of remote sensing techniques like terrestrial (TLS) and airborne laser scanner (ALS), which allow detailed investigations of a rock cliff in remote and safe mode. In particular, TLS allows the acquisition of the sub-vertical cliffs, whereas ALS provides information over wide areas with higher performances in sub-planar surfaces. These remote sensing techniques has been applied to analyze the northern rock wall of Einser-Cima (Fischleintal-Val Fiscalina, Sexten Dolomites, Bozen, Italy), whose higher portion was involved by a large (45000 m3) rock collapse occurred on October 12th, 2007. Two TLS measurements sessions were carried out, in November 2007 and in October 2008 respectively, considering two suitable viewpoints placed at about 200 m distance from the main failure surface, providing a sampling step of 10 cm. The analysis of TLS data allowed a detailed reconstruction of the surface geometry as well as a description of orientation, persistence, spacing and aperture of the rock mass discontinuity sets and the characterization of orientation and roughness of the failure planes. Moreover, comparisons between the two TLS-based point clouds allowed the analysis of displacements and deformations, as well an accurate evaluation of the open joint apertures. ALS data of the whole region acquired by the Geological Service of Bozen Province in 2004-2005 was also available. These data, having a mean sampling step of about 40-50 cm, represents the conditions before the cited 2007 landslide. In this way, direct comparison between the ALS and TLS data provided a volume estimate of the fallen rock mass. Integration of ALS and TLS data allowed also the characterization of the main structural and geomechanical features, both at the slope scale and on wider area. Finally, the obtained values about joint apertures were validated by direct measures provided by extensometers installed in higher critical joints.

Herbarium of the university of malaga (Spain): vascular plants collection.  

PubMed

The herbarium of University of Málaga (MGC Herbarium) is formed by four biological collections. The vascular plants collection (MGC-Cormof) is the main collection of the herbarium. MGC-Cormof dataset aims to digitize and publish data associated with over 76.000 specimens deposited in the collection, of which 97.2% of the specimens are identified at species level. Since 2011, the University of Malaga's Central Research Service (SCAI) has been responsible for maintaining the herbariums and the dataset. The collection is growing continuously, with an annual intake of about 1.500 specimens. Nearly 96% of the collection is digitized, by Herbar v3.7.1 software (F. Pando et al. 1996-2011), making over 73.000 specimens accessible through the GBIF network (http://data.gbif.org/datasets/resource/8105/). At present, 247 families and 8.110 taxa, distributed in angiosperms (93.97%), ferns and fern allies (4.89%) and gymnosperms (1.14%), constitute the MGC-Cormof collection. The families and genera best represented in the collection are Compositae, Leguminosae, Gramineae, Labiatae, Caryophyllaceae, Teucrium, Silene, Asplenium, Linaria and Quercus. Most of the specimens are from the Western Mediterranean Region, fundamentally Southern Spain (Andalusia: 82% of specimens) and Northern Morocco (2.17%). Approximately, 63% of the specimens are georeferenced. The identification of the specimens in the collection has been carried out by the plant biology department at the University of Malaga and plus 40% of the specimens has been reviewed by experts. The MGC-Cormof dataset has been revised by DarwinTest v3.2 tool (Ortega-Maqueda and Pando 2008) before being published in GBIF. The data included in this database are important for conservation works, taxonomy, flora, cartography, phenology, palynology, among others. El Herbario de la Universidad de Málaga (Herbario MGC) está constituido por cuatro colecciones biológicas. La colección de plantas vasculares (MGC Cormof) es la colección principal del herbario.

Nesting biology, morphological remarks, and description of the mature larva of Mellinus arvensis obscurus (Hymenoptera: Crabronidae) in Nepal  

SciTech Connect

Recently re-named as a sub-species of Mellinus arvensis, Mellinus arvensis obscurus Handlirsch 1888 was investigated ecologically and morphologically in Nepal, in order to underline the most important differences with the well known M. arvensis arvensis. Mellinus arvensis obscurus females nested in clumped aggregations on inclined plains at high altitudes, both on sunny bare soil and on a shaded grassy one. Beginning of monsoon season probably interfered with wasp activity, and females performed few provisioning flights during the day. Prey consisted of a broad range of Diptera, except for one case of a spider. Many females were observed not provisioning a nest but floating on the nesting site, and many intraspecific interactions suggested a high degree of usurpation attempts. At least one species of flies and two of ants probably acted as natural enemies of the wasp. Morphological observations on females showed that the Nepal population shares more similarities (shape of tergite I, body punctation) with the European populations than with the closer Japanese population; melanization is strong, according to west-east and altitudinal cline. The mature larva of M. arvensis obscurus Handlirsch is described, illustrated, and compared with the other mature larva of the genus. The differences between both larvae mainly lie in the presence/absence, and number or differentiation of integumental structures. We conclude that morphological traits are more important than ecological and behavioral ones in distinguishing M. arvensis obscurus from M. arvensis arvensis. (author) [Spanish] En el presente articulo se aportan los resultados y conclusiones de un estudio, llevado a cabo en Nepal, en el que se abordaron aspectos ecologicos, comportamentales y morfologicos (tanto del ultimo estado de la fase larvaria como del adulto) de Mellinus arvensis obscurus Handlirsch 1888. El principal objetivo del estudio radicaba en mostrar las principales diferencias que separan a esta subespecie de la bien estudiada subespecie nominal. Mellinus arvensis obscurus nidifica a gran altitud, en terreno inclinado, con y sin vegetacion, expuesto en mayor o menor medida al sol y en agregaciones muy compactas. Durante la estacion lluviosa la hembras llevan a cabo pocos vuelos de aprovisonamiento. Las presas pertenecen al orden de los dipteros, aunque, en una ocasion se observo el aporte de una arana. Gran numero de las interacciones intraespecificas observadas sugieren un alto grado de intentos de usurpacion de nidos. Los enemigos naturales mas sobresalientes pertenecen al orden de los dipteros y a la familia de los formicidos. Del estudio morfologico del adulto, mencionaremos que la foma del terguito 1 y la escultura del cuerpo, en las hembras de las poblaciones del Nepal, son mas semejantes a los de las hembras de las poblaciones europeas que no a los de las japonesas. De la fase larvaria se describe el ultimo estado larvario, a la vez que se compara con la otra larva madura ya descrita del genero. Las diferencias entre ambas larvas maduras radican en la presencia/ausencia, numero o diferenciacion de las estructuras tegumentarias. El estudio finaliza concluyendo que los rasgos morfologicos son mas importantes, que los aspectos ecologicos y comportamentales, a la hora de establecer una separacion entre las dos subespecies (author)

Variability of cadmium, copper and zinc levels in molluscs and associated sediments from Chile.  

PubMed

The concentrations of cadmium, copper and zinc in mussel and sediment samples collected together from eight different geographical coastal areas of Chile were determined. The mussels studied were 'Chorito Maico', 'Almejas' and 'Navajuelas Chilenas' (Perumytilus purpuratus, Semelle solida and Tagellus dombeii, respectively). Sampling was carried out in July and September 1992 and January and April 1993 (winter, spring, summer and autumn seasons in Chile, respectively). The metal levels in these mussels varied among species; there were several sites where the metal concentrations in molluscs approached or exceeded the criteria levels for Cd, Cu and Zn in shellfish products: 1, 10 and 50 ppm ww respectively, which are regarded as safe levels for human consumption. The results of metal levels in sediments showed two areas clearly polluted with Cu. Strong relationships between Cu concentrations in the three molluscs and sediments were found; weak correlations were observed for Zn in S. solida. PMID:15091389

Phytoreovirus-like sequences isolated from salivary glands of the glassy-winged sharpshooter Homolodisca vitripennis (Hemiptera: Cicadellidae)  

SciTech Connect

The salivary glands of the Glassy-winged sharpshooter (GWSS), Homalodisca vitripennis Germar 1821, (syn. H. coagulata, Hemiptera: Cicadellidae) were collected and used to produce a cDNA library. Examination by BLASTX analyses identified 2 viral sequences, one a 610-base pair fragment and a second 839-base pair fragment, both of which had significant homology to viruses within the genus Phytoreovirus. Resequencing of the fragments confirmed sequence validities. These sequences were used for in silico protein translation and BLASTP analysis confirming the established homology. While the GWSS is the primary vector of Pierce's disease of grapes, this is the first report that GWSS may be a vector of a phytoreoviruses. Phylogenetic and homology comparisons with BLASTX, BLASTP, and PAUP analyses indicated that the viral sequences isolated from GWSS were closely related to the viruses in the Family Reoviridae, Genus Phytoreovirus, specifically Rice Dwarf Phytoreovirus (RDV). RDV is the only plant reovirus that is not limited to the phloem. Phytoreoviruses are transmitted in a propagative manner by cicadellid leafhoppers (Hemiptera: Cicadellidae), which acquire and transmit them during feeding. Phytoreoviruses have been reported from Agallian, Agalliopsis, Nephotettix, and Recilia, genera of leafhoppers, with evidence for transovarial transmission. The GWSS, although considered to feed primarily from the xylem, ingests from other plant tissues, such as the phloem and mesophyll during probing similar to other leafhoppers. The feeding behavior and wide host range of the GWSS provides an overlapping condition for these two organisms, leafhopper and virus. GWSS will feed from grasses as a transitory host, and on herbaceous and woody plants as primary hosts, which may favor the acquisition and transmission of Phytoreovirus by this leafhopper. Monitoring for an increase of Phytoreovirus spread in graminaceous crops that are in proximity to vineyards or tree crop orchards, where GWSS occurs, such as in southern California, will provide a better understanding of the potential role of the GWSS as a disease vector in the spread of phytoreoviruses and other plant pathogens. The sequences have been deposited in NCBI database under the accession numbers (EF058280) for GWSS-V1, WHSg013C11 and (EF058281) for GWSS-V2, WHSg024H02. (author) [Spanish] Dos fragmentos de 610 y 839 pares de bases fueron aislados apartir de una genoteca de expresion derivada de las glandulas salivales del cucarron de las alas cristalinas (GWSS), Homalodisca vitripennis, Germar 1821 (syn. H. coagulata) el cual es vector de la enfermedad de Pierce de las uvas. Los resultados de alineamiento utilizando BLASTX, BLASTP y el analisis filogenetico utilizando PAUP indicaron que los fragmentos de DNA estaban relacionado de manera mas cercana a viruses en la familia Reoviridae, genero Phytoreovirus, y especificamente a los virus del enanismo del arroz (RDV) y al virus del tumor de las grietas (WTV). El cucarron de las alas cristalinas es un saltahoja que se alimenta no solo del xilema sino tambien del floema y del mesofilo. Saltahojas del genero Agallian, son los principales vectores de WTV, el cual infecta el floema de plantas dicotiledoneas tumoraciones en las hojas y en las raices. WTV es transmitido por saltahojas y es el unico reovirus que es capaz de infectar tanto tejidos del xilema como del floema. El comportamiento alimentario del GWSS y su amplio rango de hospederos que incluye pastos y plantas herbaceas y lenosas podria proveer la interaccion entre estos dos organismos facilitando la adquisicion y tranmision de fitoreovirus por el GWSS. Un adecuado monitoreo de el incremento en la expansion de reoviruses en cultivos de gramineas asociados al los vinedos en donde GWSS ocurre en regiones tales como el sur de California, y en general el sur de los Estados Unidos, podria proveer un mejor entendimiento del papel del GWSS como vector de fitoreovirus y otros patogenos de plantas.

Quality management systems for fruit fly (Diptera: Tephritidae) sterile insect technique  

SciTech Connect

The papers presented in this issue are focused on developing and validating procedures to improve the overall quality of sterile fruit flies for use in area-wide integrated pest management (AW-IPM) programs with a sterile insect technique (SIT) component. The group was coordinated and partially funded by the Joint FAO/IAEA Programme of Nuclear Techniques in Food and Agriculture, International Atomic Energy Agency, Vienna, Austria, under a five-year Coordinated Research Project (CRP) on 'Quality Assurance in Mass-Reared and Released Fruit Flies for Use in SIT Programmes'. Participants in the CRP from 16 countries came from both basic and applied fields of expertise to ensure that appropriate and relevant procedures were developed. A variety of studies was undertaken to develop protocols to assess strain compatibility and to improve colonization procedures and strain management. Specific studies addressed issues related to insect nutrition, irradiation protocols, field dispersal and survival, field cage behavior assessments, and enhancement of mating competitiveness. The main objective was to increase the efficiency of operational fruit fly programs using sterile insects and to reduce their cost. Many of the protocols developed or improved during the CRP will be incorporated into the international quality control manual for sterile tephritid fruit flies, standardizing key components of the production, sterilization, shipment, handling, and release of sterile insects. (author) [Spanish] Los articulos presentados en este numero se enfocan en el desarrollo y la validacion de procedimientos para mejorar la calidad total de moscas de las frutas esteriles para su uso en programas de manejo integrado de plagas en donde la tecnica del insecto esteril (TIE) es uno de los componentes clave. El grupo fue coordinado y parcialmente financiado por la Division Conjunta de Tecnicas Nucleares para la Alimentacion y la Agricultura de la FAO/OIEA, Viena, Austria, por un periodo de cinco anos bajo el proyecto de Investigacion Coordinada (PIC) sobre 'el Aseguramiento de la Calidad de Moscas de las Frutas Criadas y Liberadas para su Uso en Programas de TIE'. Los participantes en el PIC representan 16 paises con experiencia en campos de investigacion basica y aplicada. Para asegurar que los procedimientos desarrollados fueran apropiados y pertinentes, se realizaron una variedad de estudios para el desarrollo de protocolos para evaluar la compatibilidad y para mejorar los procedimientos de colonizacion y manejo de cepas salvajes. Estudios especificos trataron asuntos relacionados con la nutricion de insectos, los protocolos de irradiacion, la dispersion y supervivencia en el campo, evaluacion del comportamiento en jaulas de campo, y el mejoramiento de la competitividad sexual. Los objetivos fundamentales fueron el aumentar la eficiencia y reducir los costos de los programas operacionales de control de moscas de las frutas donde TIE es utilizada. Muchos de los protocolos desarrollados o mejorados durante el PIC seran incorporados en el Manual Internacional de Control de Calidad para Moscas Estriles de la familia Tephritidae, para estandarizar componentes claves como la produccion, esterilizacion, envio, manejo y liberacion de insectos esteriles.

USGS Publications Warehouse

Recent changes in the landscape of scientific publishing prompted the Publications Overview Committee of the American Fisheries Society (AFS) to review the Society's portfolio of scientific journals. We evaluated journals based on metrics in two categories: (1) citation-based measures of the influence of a journal on the scientific literature, and (2) measures of the cost-effectiveness of a journal (citation rate adjusted for subscription cost). Over the long-term, we found that ecology journals had far stronger citation-based influence than fisheries and aquatic sciences journals, and that journals publishing primarily basic research had stronger influence than journals publishing applied research (including four AFS journals and Fisheries magazine). In evaluating the current status of fisheries and aquatic sciences journals, we found that metrics of influence and cost-effectiveness provided considerably different portrayals of journals relative to their peers. In terms of citation-based influence, we found that the AFS journal Transactions of the American Fisheries Society (TAFS) and Fisheries magazine were competitive with highly regarded peer fisheries journals, but that North American Journal of Aquaculture (NAJA) and Journal of Aquatic Animal Health (JAAH) were less influential than their peers. The citation-based influence of North American Journal of Fisheries Management (NAJFM) was intermediate between TAFS/Fisheries and NAJA/JAAH. For journals like NAJFM and NAJA, we expect that much of the scientific influence on policy and management is not captured by citations in the primary literature, and alternative methods of evaluation may be needed. All of the AFS journals ranked highly with regard to cost-effectiveness because their subscription costs are low, and these rankings are in accordance with membership needs and the strategic mission of AFS to provide broad and timely dissemination of scientific information. We conclude by suggesting ways to increase the influence of AFS journals without compromising their accessibility and affordability, and offer advice about methods and frequency for future journal evaluations. ?? 2009.

LINEs mobilize SINEs in the eel through a shared 3' sequence.  

PubMed

We characterized members of the LINE (UnaL2) and SINE (UnaSINE1) families from the eel genome and found that these LINE/SINE partners share similar 3' tails. A retrotransposition assay in HeLa cells demonstrated that the 3' conserved tail of UnaL2 is necessary for its retrotransposition. This 3' tail is recognized in trans by the UnaL2 reverse transcriptase at a surprisingly high rate, and that of UnaSINE1 can also be recognized, thus providing experimental evidence that a SINE can be mobilized by the retrotransposition machinery of a partner LINE. We also demonstrated that short repeats at the 3' end of UnaL2 are required for retrotransposition suggesting that UnaL2 retrotransposes in a manner reminiscent of the reverse transcriptase activity of telomerases.

Effects of a conditional cash transfer programme on child nutrition in Brazil  

PubMed Central

Abstract Objective To examine the association between Brazil’s Bolsa Familia programme (BFP), which is the world's largest conditional cash transfer programme, and the anthropometric indicators of nutritional status in children. Methods Using the opportunity provided by vaccination campaigns, the Brazilian government promotes Health and Nutrition Days to estimate the prevalence of anthropometric deficits in children. Data collected in 2005–2006 for 22?375 impoverished children under 5 years of age were employed to estimate nutritional outcomes among recipients of Bolsa Família. All variables under study, namely child birth weight, lack of birth certificate, educational level and gender of family head, access to piped water and electricity, height for age, weight for age and weight for height, were converted into binary variables for regression analysis. Findings Children from families exposed to the BFP were 26% more likely to have normal height for age than those from non-exposed families; this difference also applied to weight for age. No statistically significant deficit in weight for height was found. Stratification by age group revealed 19% and 41% higher odds of having normal height for age at 12–35 and 36–59 months of age, respectively, in children receiving Bolsa Familia, and no difference at 0–11 months of age. Conclusion The BFP can lead to better nutritional outcomes in children 12 to 59 months of age. Longitudinal studies are needed to confirm these findings.

Thermodynamics of RNA duplexes modified with unlocked nucleic acid nucleotides  

PubMed Central

Thermodynamics provides insights into the influence of modified nucleotide residues on stability of nucleic acids and is crucial for designing duplexes with given properties. In this article, we introduce detailed thermodynamic analysis of RNA duplexes modified with unlocked nucleic acid (UNA) nucleotide residues. We investigate UNA single substitutions as well as model mismatch and dangling end effects. UNA residues placed in a central position makes RNA duplex structure less favourable by 4.0–6.6?kcal/mol. Slight destabilization, by ?0.5–1.5?kcal/mol, is observed for 5?- or 3?-terminal UNA residues. Furthermore, thermodynamic effects caused by UNA residues are extremely additive with ?G°37 conformity up to 98%. Direct mismatches involving UNA residues decrease the thermodynamic stability less than unmodified mismatches in RNA duplexes. Additionally, the presence of UNA residues adjacent to unpaired RNA residues reduces mismatch discrimination. Thermodynamic analysis of UNA 5?- and 3?-dangling ends revealed that stacking interactions of UNA residues are always less favourable than that of RNA residues. Finally, circular dichroism spectra imply no changes in overall A-form structure of UNA–RNA/RNA duplexes relative to the unmodified RNA duplexes.

Scienza dei servizi  

NASA Astrophysics Data System (ADS)

I servizi sono oramai centrali nella vita sociale di ogni Paese. L'aspettativa di ogni attore sociale, sia esso cittadino/utente e/o istituzione, è quella di ricevere da uno scambio che ha alla base un servizio un contributo che si caratterizza per una qualità intrinseca. Il mantenimento di tale promessa richiede all'azienda erogatrice un forte coinvolgimento, nel disegno del servizio, degli utenti ed una capacità di gestione della conoscenza; ciò è particolarmente significativo per quei servizi che si caratterizzano per una forte personalizzazione o complessità progettuale. Disegnare un servizio, metterlo in produzione e gestirne l'erogazione ha una complessità variabile in base al grado di coinvolgimento dei destinati ed alle dimensioni critiche che esprimono le condizioni di fattibilità di un servizio di qualità appropriato alle attese degli utilizzatori. Ugualmente la globalizzazione dell'economia e la scarsità delle risorse ha portato l'attenzione, ai fini della sostenibilità delle condizioni sopra richiamate, di una ricerca di modelli e strumenti che permettano una valutazione e una standardizzazione dei processi di produzione ed erogazione secondo condizioni di economicità. Tali primi e sintetici elementi hanno condotto diversi attori istituzionali, grandi imprese ed università attraverso i loro centri di ricerca, ad una azione di riflessione sul grado di "ingegnerizzazione" dei processi sottesi alla erogazione dei servizi ed in particolare ai servizi che attuano le politiche dei grandi settori di base dell'economia di una Nazione: educazione, sanità, sociale, sviluppo infrastrutture ecc.

The primary purpose of this manuscript is to provide an overview of multilevel modeling for Psychosomatic Medicine readers and contributors. The manuscript begins with a general introduction to multilevel modeling. Multilevel regression modeling at two-levels is emphasized because of its prevalence in psychosomatic medicine research. Simulated datasets based on some core ideas from the Familias Unidas effectiveness study are used to illustrate key concepts including: communication of model specification, parameter interpretation, sample size and power, and missing data. Input and key output files from Mplus and SAS are provided. A cluster randomized trial with repeated measures (i.e., three-level regression model) is then briefly presented with simulated data based on some core ideas from a cognitive behavioral stress management intervention in prostate cancer.

Determinação de elementos próprios dos asteróides troianos: comparação entre as teorias semi-analítica e sintética  

NASA Astrophysics Data System (ADS)

Além do cálculo semi-analítico de elementos próprios dos asteróides Troianos (Beaugé & Roig 2001, Icarus 153, 391), recentemente foi apresentado um novo conjunto destes elementos próprios determinado através de uma teoria sintética (Knenezevic & Milani 2003, comunicação pessoal). As bases de dados contendo estas determinações estão disponiveis na pagina web do Asteroid Dynamical Site (http://hamilton.dm.unipi.it/cgi-bin/astdys/astibo). Nesta comunicação apresentamos os primeiros resultados de um estudo comparativo entre ambos conjuntos de elementos próprios, analisando suas vantagens e desvantagens, assim como os limites de precisão de cada conjunto. Mostramos que os elementos próprios sintéticos são mais precisos que os smi-analíticos para grandes amplitudes de libração do ângulo s = l-lJup, embora acontece o contrario para os corpos cuja amplitude de libração é muito pequena. Finalmente discutimos a influencia destes erros na determinação de familias de asteroides e da estrutura resonante em torno dos pontos Lagrangeanos L4 e L5.

Approaches to community nursing research partnerships: a case example.  

PubMed

Every community is unique and has special strengths and health-related needs, such that a community-based participatory research partnership cannot be formed and implemented in a predetermined, step-by-step manner. In this article, we describe how the Community Partnership Model (CPM), designed to allow flexible movement back and forth through all action phases, can be adapted to a variety of communities. Originally developed for nursing practice, the CPM has evolved into approaches for the collaborative initiation and maintenance of community partnerships. The model is informed by the recognition that cultural, social, economic, and knowledge backgrounds may vary greatly between nurse researchers and their community partners. The Familias En Acción violence prevention project exemplifies the use of the CPM in a transcultural partnership formation and implementation process. The collaborative approaches of the model guide community and research partners to interconnect and move flexibly through all partnership phases, thereby facilitating sustainability and community self-advocacy.

Incentivos para atraer y retener personal de salud de zonas rurales del Per?: un estudio cualitativo  

PubMed Central

El objetivo fue identificar incentivos de atracción y retención en zonas rurales y distantes de Ayacucho, Perú. Fueron realizadas entrevistas en profundidad con 80 médicos, enfermeras, obstetras y técnicos (20 por grupo) de las zonas más pobres y con 11 funcionarios. No existen políticas sistemáticas de atracción y retención de personal de salud en Ayacucho. Los principales incentivos, en orden de importancia, fueron mejoras salariales, oportunidades de formación y capacitación, estabilidad laboral y nombramiento, mejoras en infraestructura y equipos, e incremento del personal. Se mencionaron también mejoras en la vivienda y alimentación, mayor cercanía con la familia y reconocimiento por el sistema de salud. Existen coincidencias y singularidades entre los distintos grupos sobre los incentivos clave para estimular el trabajo rural, que deben considerarse al diseñar políticas públicas. Las iniciativas del Estado deben comprender procesos rigurosos de monitoreo y evaluación, para asegurar que las mismas tengan el impacto deseado.

Activities of Daily Living in Mexican American Caregivers: The Key to Continuing Informal Care  

PubMed Central

La familia drives elder care in Mexican–American (MA) families, but nursing home placement can result from day-to-day caregiving demands that increase caregiver difficulty with activities of daily living (ADLs). Using life course perspective, this article describes the initial data wave of 31 MA caregivers from a descriptive, longitudinal, mixed-methods study of 110 MA caregivers and care recipients over 15 months in their caregiving trajectories. Fifteen of 31 caregivers consistently indicated “no help needed” on the Katz ADL, whereas all but one reported “help needed” during semistructured interviews with cultural brokers. In addition to the discrepancy between results on the Katz ADL and interviews, findings include consideration of nursing home placement by moderately acculturated caregivers and minimization of their illnesses by caregivers. Additional methods of MA caregiver assessment may be needed due to the questionable accuracy of the Katz ADL; additional research should explore minimization and acculturation in MA caregivers.

[Implementation of multi-strategy programs: a proposal for an evaluation matrix].  

PubMed

The programs that seek to achieve comprehensive changes involve the relationship between different public policies, understanding the diversity of social demands in each context and enhancing a participative dynamic. Due to the complexity of these experiences, it is important to review the traditional perspectives and discuss alternatives. Based on the analytical framework of the so-called theory-driven evaluation, the core focus of which is the analysis of the validity of the concepts that link processes and results and the exploratory case study of the qualitative character of the federal Bolsa Familia cash transfer program, the paper proposes a methodological matrix as its main result to support the evaluation of interventions related to health promotion, food security and poverty reduction.

The impact of public expenditure on undernourishment distribution in Mexico.  

PubMed

The status of undernourishment in children under the age of five in Mexico is open to debate. Linked to poverty, underweight and stunting, the rates of undernourishment are reported to be diminishing, although poverty remains an incessant problem. This study was done to determine whether there is an association between public expenditure and underweight and stunting distribution in Mexico based on data from the 2006 health and population census and from macroeconomic, social, and demographic variables. We used principal component analysis to reduce the number of variables and analyze their behavior. Multiple regressions showed that underweight and stunting are significantly associated with the marginalization index, support from the Sistema Nacional para el Desarrollo Integral de la Familia (DIF) supplies and breakfast program, the gross domestic product per capita, and expenditure from the Opportunities program. Further, public expenditure aimed to combat undernourishment is inadequately oriented to address the needs of the poor. PMID:23986379
