Research has shown that individual-level characteristics such as socioeconomic status and political interest are becoming more important as predictors of news consumption in a rapidly changing media environment. Despite this general trend, this article argues that the importance of individual-level predictors of news consumption varies between national media environments. We use extensive survey data from 16 European countries and multilevel modeling in order to investigate both contextual-level and cross-level effects on news consumption. The results show that media environment characteristics have additional effects on news consumption beyond the effects of individual-level characteristics such as education and political interest, but also moderating impacts on these individual-level predictors of news consumption. More specifically, national media environments characterized by higher levels of newspaper-centrism are related to smaller gaps in newspaper reading between those with high and low levels of education and political interest. Lower degrees of newspaper-centrism are, on the other hand, related to a weaker “lower-class bias” of television news and larger gaps in news consumption between those with and without high political interest. These findings are discussed in light of previous research on news consumption, knowledge, and participation gaps as well as cross-national comparative research.  相似文献

Bangladesh has made remarkable progress in increasing education access in the last 20 years. However, substantial inequalities in educational attainment remain even though equity in education is a central government objective. The article argues that weaknesses in education sector governance are crucial to understanding these persistent inequalities. At the level of the budget, anti‐poor biases in allocation decisions are shown to be the result of the budget's role in political management and the lack of effective accountability mechanisms. The spearhead of government attempts to address education inequality at the primary level has been the conditional cash transfer programme for poor children. The article shows that the programme has failed to target the poor and suggests that this has been due to the weaknesses and contradictions in the governance of the programme. Strengthening the links between policy and implementation through improvements in the governance of the sector are crucial if inequality is to be addressed and national education goals achieved.

Each year, reports occur of deaths in individuals, while struggling against physical restraint. The mechanism of these deaths remains unclear. This study aimed to determine the effect of wrist restraint on cardiorespiratory function during maximal exercise. Twelve healthy volunteers underwent 3 incremental maximal exercise tests on a cycle ergometer. In a randomized order, they exercised while unrestrained, with the wrists tied in front of the body or wrists tied behind the back. The primary outcome measures were the number of minutes exercised in each position and heart rate and whole blood lactate level for each stage and on reaching maximum exercise capacity. The mean exercise duration was 19 minutes 6 seconds unrestrained (95% confidence interval [CI] 16 minutes 52 seconds to 20 minutes 57 seconds), 18 minutes 51 seconds (95% CI 17 minutes 51 seconds to 20 minutes 50 seconds) with arms restrained in front and 16 minutes 51 seconds (95% CI 14 minutes 6 seconds to 19 minutes 20 seconds) with the arms restrained behind the body (P = 0.16). There was no significant difference in heart rate or lactate measurements. It is probable that other factors make a more important contribution than wrist restraint behind the body to cardiorespiratory compromise in a struggling and fatigued individual.  相似文献

This study analyzes reinforcing spirals between news media use and two manifestations of political engagement: political interest and participation intention. Drawing on a three-wave panel study among adolescents, we test the Virtuous Circle Thesis (VCT) in both an online and an offline setting, by distinguishing between selection effects and media effects as key ingredients of the VCT. Overall, the findings lend mixed support to the general argument. While the relationship between specific forms of news media use and political interest appears to be driven primarily by selection effects, reciprocal relations were found mainly between television news and participation intention. The VCT assumption of reciprocal influences was supported most clearly when adolescents’ total news media use was considered. Taken together, virtuous circles appeared to operate rather similarly online and offline.  相似文献

This study uses a tracer survey of secondary school completers in Tanzania to analyse the impact of educational qualifications on labour market earnings. We show that the rates of return to the highest educational qualifications for wage employees are not negligible and, at the margin, provide an investment incentive. However, we find little evidence of human capital effects in the earnings determination process for the self-employment sector. Introducing controls for father's educational background and a set of school fixed effects designed to proxy for school quality and potential labour market network effects reduces the estimated rates of return to educational qualifications. A comparison of our results with the available evidence from other countries in the region suggest that, despite an extremely small secondary and university education system, the private rates of return to education in the Tanzanian wage employment sector are comparatively low.  相似文献

Congenital diaphragmatic hernia (CDH) is a defect seen in approximately 1 in 3500 live births. A complication of CDH is the herniation of abdominal contents into the chest cavity through the defect, which may prevent normal intrauterine development of the lungs. The resultant pulmonary hypoplasia and pulmonary hypertension causes respiratory distress in the newborn, usually requiring some form of intervention before the defect is surgically corrected (Embryology for Surgeons. Baltimore, MD: Williams & Wilkins; 1994:491-539). Extracorporeal membrane oxygenation, which involves cannulation of the superior vena cava (SVC), is often used to manage these infants. However, the mediastinal shift that often occurs with CDH can cause an abnormal acute angulation of the SVC, which during cannulation can result in trauma and possible perforation of the SVC. We present 2 autopsy cases where the infants accidentally died as a result of extracorporeal membrane oxygenation cannulation.  相似文献
