Cambiando el canal: An ethnographic study on American Latino audiences\u27 preferred Spanish media outlet based on their ethnic dialect, demographic location and adolescent upbringing

With the current issues revolving around the Latino community including the lack of Latino inclusivity within the media and the absence of Hispanic heritage nuances within second- and third-generation Latinos, this study looks into the reasoning behind Latinos’ preferred Spanish media network. By combining qualitative and quantitative reasoning, this mixed-methodology breaks down the issues revolving around Spanish speaking households and what factors cause them to choose Univision or Telemundo. In connection to my previous McNair research, this thesis will use previous Hispanic television research, the survey results from a ten-question survey to individual Latinos and a series of interviews with Latin men and women asking them questions about which Spanish-based network they prefer. By using these selected methods, the research will show a direct miscorrelation (and perhaps misunderstanding) on the reason Latinos pick their preferred Spanish media network. Our findings showed that many factors are taken into account when deciding which network they prefer, including what their parents prefer and whether they are a second or third-generation American Latino. The results also showed many American Latinos between the ages of 18-34 only watch Spanish-based television because their parents watch it, without thinking about how the network caters to their dialectal needs

A Critical Assessment of Geographic Clusters of Breast and Lung Cancer Incidences among Residents Living near the Tittabawassee and Saginaw Rivers, Michigan, USA

Objectives. To assess previously determined geographic clusters of breast and lung cancer incidences among residents living near the Tittabawassee and Saginaw Rivers, Michigan, using a new set of environmental factors. Materials and Methods. Breast and lung cancer data were acquired from the Michigan Department of Community Health, along with point source pollution data from the U.S. Environmental Protection Agency. The datasets were used to determine whether there is a spatial association between disease risk and environmental contamination. GIS and spatial techniques were combined with statistical analysis to investigate local risk of breast and lung cancer. Results and Conclusion. The study suggests that neighborhoods in close proximity to the river were associated with a high risk of breast cancer, while increased risk of lung cancer was detected among neighborhoods in close proximity to point source pollution and major highways. Statistically significant (P ≤ .001) clusters of cancer incidences were observed among residents living near the rivers. These findings are useful to researchers and governmental agencies for risk assessment, regulation, and control of environmental contamination in the floodplains

Impact of Performance - B ased Contracting on Product Reliability : An Empirical Analysis

Using a proprietary data set provided by a major manufacturer of aircraft engines, we empirically investigate how product reliability is impacted by the use of two different types of after-sales maintenance support contracts: time and material contracts (T&MC) and performance-based contracts (PBC). We offer a number of competing arguments based on the theory of incentives that establish why product reliability may increase or decrease under PBC. We build a two-stage econometric model that explicitly accounts for the endogeneity of contract choices, and find evidence of a positive and significant effect of PBC on product reliability. The estimation of our model indicates that product reliability is higher by 25%–40% under PBC compared to under T&MC, once the endogeneity of contract choice is taken into account. Our results are consistent with two mechanisms for reliability improvement under PBC: more frequent scheduled maintenance and better care performed in each maintenance event

Service Competition and Product Quality in the U.S. Automobile Industry

We study the impact of service attributes (warranty length, after-sales service quality) on consumer demand in the U.S. automobile industry, examining the presence of complementarities/substitution between service attributes and product quality. Our results estimate a median willingness to pay for one year of a warranty of approximately $850, which is equivalent to 3.1% of the median vehicle price in our sample. We find that, for a car with median characteristics, the effect on consumer utility of a 1% price decrease is equivalent, all else being equal, to increasing product quality by 2.2%, and is in turn equivalent to increasing the warranty length by 8%. Our results also indicate that service attributes play a compensatory role with respect to product quality; i.e., the impact of warranty length and service quality on demand increases when product quality decreases. Conversely, both service metrics are complementary with respect to demand; i.e., the better the service quality, the higher the marginal effect of longer warranties. Our results thus imply that, in our period of analysis, warranties played a more important role for American firms than for foreign firms, consistent with the fact that American manufacturers exhibited lower product quality and higher service quality than non-American firms

Labor supply response to income taxation in Mexico

Resumen: El presente artículo examina el efecto de las tasas marginales del impuesto sobre la renta en el mercado laboral en México, utilizando una versión modificada del modelo de tributación sobre la renta personal de Rosen (1976). El estudio analiza las reacciones de los trabajadores asalariados del sector formal ante los cambios en la tasa marginal del impuesto sobre la renta. Prestamos especial atención a la muestra, con el fin de controlar en nuestros cálculos el problema del alto índice de evasión fiscal en México. Comprobamos como las horas de trabajo disminuyen cuando las tasas marginales del impuesto sobre la renta aumentan. Abstract: This paper examines the effect of marginal income tax rates on labor supply in Mexico using a modified version of Rosen´s (1976) personal income taxation model. The study analyzes how salaried workers of the formal sector react to changes in the marginal income tax rate. Special attention is given to the sample, in order to control the problem of the high level of tax evasion in Mexico in our estimation. We find evidence that hours of work diminish when marginal income tax rates increase

Lasso Estimation of an Interval-Valued Multiple Regression Model

A multiple interval-valued linear regression model considering all the cross-relationships between the mids and spreads of the intervals has been introduced recently. A least-squares estimation of the regression parameters has been carried out by transforming a quadratic optimization problem with inequality constraints into a linear complementary problem and using Lemke's algorithm to solve it. Due to the irrelevance of certain cross-relationships, an alternative estimation process, the LASSO (Least Absolut Shrinkage and Selection Operator), is developed. A comparative study showing the differences between the proposed estimators is provided

Finite-Temperature Collective Dynamics of a Fermi Gas in the BEC-BCS Crossover

We report on experimental studies on the collective behavior of a strongly interacting Fermi gas with tunable interactions and variable temperature. A scissors mode excitation in an elliptical trap is used to characterize the dynamics of the quantum gas in terms of hydrodynamic or near-collisionless behavior. We obtain a crossover phase diagram for collisional properties, showing a large region where a non-superfluid strongly interacting gas shows hydrodynamic behavior. In a narrow interaction regime on the BCS side of the crossover, we find a novel temperature-dependent damping peak, suggesting a relation to the superfluid phase transition

Análisis tipológico de bloques lineales de vivienda social: España 1950-1983. El caso de Andalucía occidental

A main challenge that cities will need to face in the next few years is the regeneration of the social housing estates built during the decades of 1950s, 1960s and 1970s. One of the causes of their obsolescence is the mismatch between their hous-ing typologies and the contemporary needs. The main target of this study is to contribute to take a step forward in the un-derstanding of these typologies to be able to intervene on them efficiently. With this purpose, a study on 42 linear blocks built in Spain between 1950 and 1983 in western Andalusia has been carried out. The analysis includes three stages: 1) classification of the houses in recognizable groups; 2) an identification of the most used spatial configurations and 3) definition of their programmatic and size characteristics. As a result, a characterization of linear blocks is proposed as a reference model for future regenerative interventions.La regeneración de los grandes conjuntos de vivienda social construidos en las décadas de 1950, 1960 y 1970 se ha convertido en uno de los grandes retos que la ciudad tendrá que afrontar en los próximos años. Una de las causas de su obsolescencia es la inadecuada adaptación de sus tipologías de vivienda a los requisitos y expectativas de la sociedad contemporánea. El objetivo principal de este estudio es avanzar en el conocimiento de estas tipologías para poder intervenir eficazmente sobre ellas. Con este propósito se han analizado 42 bloques lineales proyectados entre 1950 y 1983 en Andalucía occidental. El estudio incluye tres fases de análisis: 1) clasificación de las viviendas en grupos reconocibles; 2) identificación de las distribuciones más utilizadas, y 3) análisis de sus características dimensionales y programáticas básicas. Todo esto permite establecer una caracterización de la vivienda social en bloque lineal que puede servir de referencia para futuras intervenciones de regeneración
