Religion and Attitudes toward Same-Sex Marriage among U.S. Latinos

Objectives. This study examines links between multiple aspects of religious involvement and attitudes toward same-sex marriage among U.S. Latinos. The primary focus is on variations by affiliation and participation, but the possible mediating roles of biblical beliefs, clergy cues, and the role of religion in shaping political views are also considered. Methods. We use binary logistic regression models to analyze data from a large nationwide sample of U.S. Latinos conducted by the Pew Hispanic Forum in late 2006. Results. Findings highlight the strong opposition to same-sex marriage among Latino evangelical (or conservative) Protestants and members of sectarian groups (e.g., LDS), even compared with devout Catholics. Although each of the hypothesized mediators is significantly linked with attitudes toward same-sex marriage, for the most part controlling for them does not alter the massive affiliation/attendance differences in attitudes toward same-sex marriage. Conclusions. This study illustrates the importance of religious cleavages in public opinion on social issues within the diverse U.S. Latino population. The significance of religious variations in Hispanic civic life is likely to increase with the growth of the Latino population and the rising numbers of Protestants and sectarians among Latinos

Faith, Race-Ethnicity, and Public Policy Preferences: Religious Schemas and Abortion Attitudes among U.S. Latinos

Research has demonstrated that white conservative Protestants are more opposed to abortion than their Catholic counterparts. At the same time, conservative Protestantism has made significant inroads among U.S. Latinos. This study augments existing research on religion and racial-ethnic variations in abortion attitudes by comparing levels of support for legalized abortion among Catholic and conservative Protestant Latinos. Data are drawn from a nationally representative sample of U.S. Latinos. Significantly greater opposition to abortion is found among religiously devout conservative Protestant Latinos when compared with their Catholic counterparts. Latino Catholicism, which functions as a near-monopolistic, highly institutionalized faith tradition among Hispanics, produces weaker antiabortion attitudes than those exhibited in Latino conservative Protestantism. Among Latinos, conservative Protestantism operates as a niche voluntaristic faith. These factors produce a religious schema that yields robust antiabortion attitudes. This study has important implications for understanding the intersection of race-ethnicity, religion, and public policy preferences

Implantation of 3D-Printed Patient-Specific Aneurysm Models into Cadaveric Specimens: A New Training Paradigm to Allow for Improvements in Cerebrovascular Surgery and Research.

AimTo evaluate the feasibility of implanting 3D-printed brain aneurysm model in human cadavers and to assess their utility in neurosurgical research, complex case management/planning, and operative training.MethodsTwo 3D-printed aneurysm models, basilar apex and middle cerebral artery, were generated and implanted in four cadaveric specimens. The aneurysms were implanted at the same anatomical region as the modeled patient. Pterional and orbitozygomatic approaches were done on each specimen. The aneurysm implant, manipulation capabilities, and surgical clipping were evaluated.ResultsThe 3D aneurysm models were successfully implanted to the cadaveric specimens' arterial circulation in all cases. The features of the neck in terms of flexibility and its relationship with other arterial branches allowed for the practice of surgical maneuvering characteristic to aneurysm clipping. Furthermore, the relationship of the aneurysm dome with the surrounding structures allowed for better understanding of the aneurysmal local mass effect. Noticeably, all of these observations were done in a realistic environment provided by our customized embalming model for neurosurgical simulation.Conclusion3D aneurysms models implanted in cadaveric specimens may represent an untapped training method for replicating clip technique; for practicing certain approaches to aneurysms specific to a particular patient; and for improving neurosurgical research

A DFT and QTAIM Study of Organic Molecules (PAZ, CHR, TCNQ, PTZ, PMA and BINA) with Possible Application in Molecular Electronic

Se hicieron cálculos UB3LYP con las bases DGDZVP y 6-311G(d) para estudiar seis moléculas orgánicas (PAZ, CHR, TCNQ, PTZ, PMA y BINA). Se usó la teoría cuántica de átomos en moléculas (QTAIM) para describir los tipos de enlace químico presentes en estas moléculas. Las energías de interacción se correlacionaron con los valores de la densidad electrónica, la densidad de energía potencial y el laplaciano de la densidad en los puntos críticos de enlace (BCP). Las interacciones C-S, C-N, C-C, C-O y C-H se clasificaron como capa compartida y los enlaces S-S, como capa cerrada usando el laplaciano de ρ(r). Cuando se consideró la relación |V(r)|/G(r), se clasificaron las interacciones S-S como capa cerrada intermedia.Abstract: UB3LYP calculations with the DGDZVP and 6-311G(d) basis sets have been used to study 6 organic molecules (PAZ, CHR, TCNQ, PTZ, PMA and BINA). Bader’s Quantum Theory of Atoms in Molecules (QTAIM) has been used for describing different types of chemical bonding present in these molecules. Interactions energies were correlated with the values of the electron density, the potential energy density, and the Laplacian of the density at the bond critical points (BCPs). The C-S, C-N, C-C, C-O y C-H interactions were classified as shared shell and the S-S bonds as closed shell using the Laplacian of ρ(r). When it was considered the ratio |V(r)|/G(r), we could classify the S-S interactions as transit closed shell

Clasificación del álgebra de Lie, leyes de conservación y soluciones invariantes para un caso particular de la ecuación generalizada e Levinson-Smith

In this study, we examine a specific instance of the generalized Levinson-Smith equation, which is linked to the Liènard equation and holds significant importance from the perspectives of physics, mathematics, and engineering. This underlying equation has practical applications in mechanics and nonlinear dynamics and has been extensively explored in the qualitative scheme. Our approach involves applying the Lie group method to this equation. By doing so, we derive the optimal generating operators for the system that pertain to the specific instance of the generalized Levinson-Smith equation. These operators are then used to define all invariant solutions associated with the equation. In addition, we demonstrate the variational symmetries and corresponding conservation laws using Noether's theorem. Finally, we categorize the Lie algebra related to the given equation.En este estudio, examinamos una instancia específica de la ecuación generalizada de Levinson-Smith, que está vinculada con la ecuación de Liènard y tiene una gran importancia desde las perspectivas de la física, las matemáticas y la ingeniería.

Nuestro enfoque implica aplicar el método de grupos de Lie a esta ecuación. Al hacerlo, obtenemos los operadores generadores óptimos del sistema que se refieren a la instancia específica de la ecuación generalizada de Levinson-Smith.

Además, demostramos las simetrías variacionales y las leyes de conservación correspondientes utilizando el teorema de Noether. Finalmente, categorizamos el álgebra de Lie relacionada con la ecuación dada

Antibiotic Resistance in Animal and Environmental Samples Associated with Small-Scale Poultry Farming in Northwestern Ecuador

The effects of animal agriculture on the spread of antibiotic resistance (AR) are cross-cutting and thus require a multidisciplinary perspective. Here we use ecological, epidemiological, and ethnographic methods to examine populations of Escherichia coli circulating in the production poultry farming environment versus the domestic environment in rural Ecuador, where small-scale poultry production employing nontherapeutic antibiotics is increasingly common. We sampled 262 “production birds” (commercially raised broiler chickens and laying hens) and 455 “household birds” (raised for domestic use) and household and coop environmental samples from 17 villages between 2010 and 2013. We analyzed data on zones of inhibition from Kirby-Bauer tests, rather than established clinical breakpoints for AR, to distinguish between populations of organisms. We saw significantly higher levels of AR in bacteria from production versus household birds; resistance to either amoxicillin-clavulanate, cephalothin, cefotaxime, and gentamicin was found in 52.8% of production bird isolates and 16% of household ones. A strain jointly resistant to the 4 drugs was exclusive to a subset of isolates from production birds (7.6%) and coop surfaces (6.5%) and was associated with a particular purchase site. The prevalence of AR in production birds declined with bird age (P 0.01 for all antibiotics tested except tetracycline, sulfisoxazole, and trimethoprim-sulfamethoxazole). Farming status did not impact AR in domestic environments at the household or village level. Our results suggest that AR associated with small-scale poultry farming is present in the immediate production environment and likely originates from sources outside the study area. These outside sources might be a better place to target control efforts than local management practices

Endoventricular patch plasty for dyskinetic anteroapical left ventricular aneurysm increases systolic circumferential shortening in sheep

ObjectiveEndoventricular patch plasty (Dor procedure) has gained favor as a surgical treatment for heart failure associated with large anteroapical myocardial infarction. We tested the hypotheses that the Dor procedure increases systolic circumferential shortening and longitudinal shortening in noninfarcted left ventricular regions in sheep.MethodsIn 6 male Dorsett sheep, the left anterior descending coronary artery and its second diagonal branch were ligated 40% of the distance from the apex to the base. Sixteen weeks after myocardial infarction, a Dor procedure was performed with a Dacron patch that was 50% of the infarct neck dimension. Two weeks before and 2 and 6 weeks after the Dor procedure, animals underwent magnetic resonance imaging with tissue tagging in multiple short-axis and long-axis slices. Fully three-dimensional strain analyses were performed. All 6 end-systolic strain components were compared in regions 1 cm, 2 cm, 3 cm, and 4 cm below the valves, as well as in the anterior, posterior, and lateral left ventricular walls and the interventricular septum.ResultsCircumferential shortening increased from before the Dor procedure to 6 weeks after repair in nearly every left ventricular region (13/16). The greatest regional change in circumferential shortening was found in the equatorial region or 2 cm below the base and in the posterior wall (from 9.0% to 18.4%; P < .0001). Longitudinal shortening increased 2 weeks after the Dor procedure but then returned near baseline by 6 weeks after the Dor procedure.ConclusionThe Dor procedure significantly increases systolic circumferential shortening in nearly all noninfarcted left ventricular regions in sheep
