“…These scholars (Lopez-Escobar et al, 1998;Kiousis et al, 1999;Golan and Wanta, 2001;McCombs and Ghanem, 2001) suggest a framing effect whereby attribute salience is transmitted to the public. Attributes may be defined as cognitive-concrete information about a particular political candidate's stand on specific issues for example-or affective, whether a particular question is reported in a positive or negative light.…”

Low density lipoprotein (LDL) particle size is inversely associated with plasma triglyceride concentration in cross-sectional analyses. In the present study, changes in the LDL particle size of 227 participants of the Framingham Offspring Study were analyzed longitudinally by nondenaturing gradient gel electropho-resis at two examinations that were separated by 3-4 years. All subjects had triglyceride concentrations <400 mg/dl at both exams. Using laser scanning densitometry to assess mean LDL particle size, 56% of samples displayed a change in size: 41% had a one-band size change, 13% had a two-band change, and 2% had a three-band change. These changes in size corresponded to a 15% change in pattern type, based on pattern A and B terminology. There was a significant inverse association between change in LDL size and change in triglyceride (/><0.0001) and glucose (p<0.004) concentrations, body weight (p<0.02), and age (p<0.03). There was also a significant positive association with change in high density lipoprotein (HDL) cholesterol concentration (p<0.0001). Change in LDL cholesterol concentration, as calculated by use of the Friedewald formula, however, showed no significant association with change in LDL size (p<0.9). There was also no significant association with change in smoking or blood pressure, but there was a nonsignificant inverse trend associated with alcohol intake (p<0.08j. Women had more significant changes than men, but the relation between change in LDL size and change in lipids was the same for women and men. In stepwise regression analyses of biochemical indices, change in triglyceride concentration produced the best single-variable model (r=0.460). When change in HDL cholesterol concentration was added to the model, the r value increased slightly to 0.481 for the two-variable model. No other variables entered the model. We conclude that the amount of circulating triglyceride appears to be the single most important factor affecting LDL particle size and that LDL size can be modulated by changes in plasma triglyceride concentration.

“…Políticas para aumentar la cobertura informativa relacionada con los principios de cultura de la legalidad Si el número de noticias es bajo, las referencias a los principios mencionados incluidos en el flujo informativo sobre crimen organizado, violencia y la guerra contra el tráfico de drogas podría no hacer una diferencia real en la percepción y actitudes del público. Las menciones constantes en una cobertura abundante son necesarias para colocar estos temas en las agendas individuales de lectores y audiencias (Escobar, Llamas y McCombs, 1998;McCombs, 2004;McCombs y Bell, 1996), y para "cultivar" en ellos las cogniciones y actitudes a largo plazo conducentes a un refuerzo de la cultura de la legalidad (Gerbner, 1998;Morgan y Shanahan, 2010;Nabi y Sullivan, 2001). …”

ResumenEste trabajo analiza y discute la cobertura noticiosa sobre el crimen organizado, la violencia y la guerra del Gobierno mexicano contra el narcotráfico en ocho periódicos de la región fronteriza México-Texas. El propósito fue identificar el grado en el que la cobertura promueve u obstaculiza los principios de la cultura de legalidad. Con base en el diagnóstico, el trabajo sugiere posibles políticas para que los periodistas, autoridades locales y federales y profesores de escuelas de Periodismo y Comunicación puedan tomar para reforzar la cultura de la legalidad a través de los medios noticiosos. El trabajo se basó en un análisis de contenido de dos semanas de cobertura de ocho periódicos diarios con circulación en la región fronteriza México-Texas: El Diario (Nuevo Laredo), El Mañana (Reynosa), Noreste (Matamoros) y El Norte en el noreste mexicano, y The Laredo Morning Times (Laredo, Texas), McAllen Monitor (McAllen), The Brownsville Herald (Brownsville) y The Express-News (San Antonio) en el sureste de Texas. La unidad de análisis fue la noticia sobre inseguridad, violencia, narcotráfico, corrupción o combate al crimen organizado en ambos lados de la frontera. El trabajo concluye con una discusión sobre las implicaciones de la cobertura actual, así como con recomendaciones puntuales de posibles políticas que los actores involucrados podrían tomar para promover, reforzar y consolidar la cultura de la legalidad en los lectores y ayudar en el establecimiento de bases para una solución a largo plazo del crimen y la violencia en la región.

“…Recently, some scholars have suggested a second-level agenda-setting effect, the 'attributes' associated with a particular issue or object (Lopez-Escobar et al, 1998;Kiousis et al, 1999;Golan and Wanta, 2001;and McCombs and Ghanem, 2001). Second-level effects transmit attribute salience to the public.…”

Images of Globalisation in the Mass Media

Increasing flows of goods, capital and labour across various national borders have signalled the ever-increasing integration or 'globalisation' of international markets. The impacts of globalisation are complex and multidimensional and have been intensely debated in the academic literature. Likewise, globalisation and its impacts have also gained attention in the mass media. Yet findings on the way globalisation has been portrayed in the mass media are mixed. In this paper, we examine the conceptual evolution and overall progression of tone of globalisation coverage in the Associated Press from 1984 to 2004. We find that AP reporters have weaved a number of key themes in their stories: growth and efficiency, poverty, employment, environment and migration among others. More-over, we find 'balance' in reporting to the extent that both sides of an argument are presented in an article. However, in absolute terms reporting is skewed in favour or against a specific issue depending on story narrative employed. Our empirical results go some way to reconciling why news organisations feel they present balanced and objective coverage while proponents and opponents on a specific issue feel that coverage is biased one way or the other.
