Learning from the news: Experiments in media,modality, and reporting about star wars

This study explores what ordinary American adults learn from news reported in different communications modalities and media. In the first experiment, the text of news items about Star Wars is held constant but the communications modality varies. In the second experiment, news reports reflect the journalistic style of television, newspaper, and magazine reporting. In the modality experiment, subjects learned equally well from the audiovisual, audio, or print versions of the stories. In the media experiment, subjects in the magazine and television conditions gained substantially more information than those in the newspaper condition; but when subjects were asked to apply information to policy judgments about Star Wars, magazine readers were more dovish than television viewers. For Star Wars news, it appears that the content and characteristic style of a news medium have important effects on news comprehension, particularly for the least informed and least interested members of the public.     

The Local News Story: Is Quality a Choice?

The conventional wisdom about local TV news is that quality journalism does not sell and that only by focusing on crime, disasters, and other “soft news” can newscasts get good ratings. Political scientists have decried the poor quality of TV news as a betrayal of the press's mandate to inform citizens of the important policy issues of the day so that they can hold government officials accountable. This study tests the proposition that audiences prefer low effort, tabloid journalism by looking at external measures of commercial success—the Nielsen ratings data. Utilizing data from a 5‐year study matching the content quality of 33,911 local news stories from 154 TV stations in 50 TV markets nationwide to corresponding ratings success, we show that solid reporting and a focus on significant issues actually produce better ratings than slapdash or superficial tabloid journalism. Additionally, we find that strategy-oriented coverage of political campaigns that focuses on the horserace does not build an audience. These surprising results have practical implications for democratic practice and local TV news production.     

On the margins of soy farms: traditional populations and selective environmental policies in the Brazilian Cerrado

In the Cerrado, the expansion of soybean cultivation since the 1990s has coincided with the strengthening of environmental regulations. We analyze how the two main environmental policies – Protected Areas and the Forest Code – have played out at the ground level in western Bahia state. These policies in Cerrado have not been designed to curb the expansion of this agricultural frontier. These norms have, on the contrary, accommodated this expansion because the way environmental managers selectively choose environmental problems and publicize them through specific information systems depreciates traditional fire-dependent production systems. These ‘politics of selection’ are likely to increase competition for resources in the margins of soybean agriculture, which is where traditional populations have now become confined.     

Elimination rates of breath alcohol

Legal driving limits are set coequally with 0.5 g/L blood alcohol concentration (BAC) or 0.25 mg/L breath alcohol concentration (BrAC) in Austria as well as in other European countries. As mostly some time elapses between BrAC measurement and driving offence, a back calculation of alcohol concentrations is often required. The calculation of hourly BrAC elimination rates can thereby help to avoid unnecessary variances. A study with 59 participants was performed under social conditions. BrAC was determined with the legally accredited Alcotest 7110 MK III A every 30 min, and concomitantly venous blood samples were drawn. Five hundred and four BrAC/BAC value pairs were evaluated. The overall mean peak BrAC was calculated with 0.456 mg/L (±0.119 mg/L standard deviation). The mean hourly BrAC elimination rate was overall determined with 0.082 mg/L per h (0.050–0.114, 95% range). Mean rate of females (0.087 mg/L h⁻¹) and the according 95% limits were statistically significantly higher than of males (mean rate 0.078 mg/L h⁻¹, p < 0.04). Our results confirm the possibility to implement hourly BrAC elimination rates, provided that adequate statistical ranges and basic forensic scientific rules that have been set up for alcohol back calculations are observed.

How do GM/non GM coexistence regulations affect markets and welfare?

This paper presents a theoretical economic model assessing the effects of the level of mandatory genetically modified (GM) and non-GM coexistence regulations on market and welfare outcomes. We assume vertical differentiation of GM and non-GM goods on the consumer side. Producers of non-GM crops face a probability of having their harvest downgraded if gene flow from GM fields raises its content in genetically modified organisms (GMOs) above the labeling threshold. The government may impose on GMO producers mandatory ex ante isolation distances from non-GM fields in order to decrease the probability of non-GM harvest downgrading. It may also introduce an ex post compensation to non-GMO farmers for profit losses due to harvest downgrading, with a compensation fund financed by GMO producers and/or the state. Assuming endogenous crop choices and prices, we study the effects of ex ante regulation and ex post liability on four outcomes: market equilibrium, the achievement of coexistence, and both global and interest group welfare.
