MADD Massachusetts versus Senator Burke: a media advocacy case study.

In 1991, the Massachusetts legislature considered a bill that would have allowed a drunk driving defendant's refusal to take a breathalyzer test to be admitted as evidence in a criminal trial. After the measure passed in both houses, a state senator used a parliamentary maneuver to prevent it from being prepared for the governor's signature. Mothers Against Drunk Driving (MADD) employed media advocacy techniques to alert the public, but the senator was unyielding and the legislative calendar ran out with the bill unsigned. Because of MADD's efforts, however, the senate president put the bill on a "fast track" the following year. The news media's focussed attention on MADD's protests exposed deep schisms among its volunteer leadership regarding the nature and purpose of the organization and the appropriateness of using confrontational media strategies advance its agenda. Paralyzed by the lack of consensus, MADD Massachusetts was rendered a far less effective advocate for policy change.

Options for increasing organ donation: the potential role of financial incentives, standardized hospital procedures, and public education to promote family discussion.

Required request laws that mandate hospital personnel to request organ donations have not substantially increased the supply of organs for transplantation. Frustration caused by the continuing shortage of organs has led several experts to promote controversial options for expanding the pool of available organs, including the offer of financial incentives. Pilot programs to test the use of incentives are warranted, but such experiments must be approached cautiously, given the moral qualms they might raise and the availability of other options. One promising strategy is to install standardized hospital procedures to ensure that all potential donors are identified, that every family is approached about the possibility of donation, and that the request is properly structured. The second strategy is to refocus public education to encourage family discussion about organ donation so that the families of those individuals who are disposed to donate will be more likely to grant consent when asked.

A review of national television PSA campaigns for preventing alcohol-impaired driving, 1987-1992.

We present a content analysis of 137 public service announcements (PSAs) focused on alcohol-impaired driving that aired nationally on U.S. television between 1987 and 1992. Our findings include the following: 1) Most PSAs were intended to reach an undifferentiated general audience, not necessarily those who are at greatest risk for driving after drinking. 2) Most PSAs were designed to create awareness of the problem of alcohol-impaired driving or to promote individual behavior change. 3) More PSAs were developed on the use of designated drivers than on any other subject. 4) About two-thirds of the PSAs included one or more celebrities who speak directly to the audience. Past media campaigns have tended to ignore the fact that people's behavior is profoundly shaped by their environment, which in turn is shaped by public policy. We recommend that future mass media campaigns against alcohol-impaired driving focus on building support for changes in institutional structures, public policy or law that will motivate, support, and sustain the efforts of individuals to alter their behavior. Television PSAs can play an important but somewhat limited role in support of this effort. Greater emphasis will need to be given instead to media advocacy strategies, including paid radio advertising. We further recommend that the principal organizations concerned about alcohol-impaired driving share their plans and develop a common communications strategy that will advance the public policy agenda proposed by the Surgeon General's Workshop on Drunk Driving.

Protein-protein interactions and glycerophospholipids in bromovirus and nodavirus RNA replication.

The plant bromoviruses and animal nodaviruses are distinct groups of positive strand RNA viruses that have proven to be useful models for RNA replication studies. Bromoviruses encode two large proteins required for RNA replication: 1a contains domains implicated in helicase and capping functions, and 2a contains a central polymerase-like domain. Using immunoprecipitation and far-western blotting, we have now shown that 1a and 2a form a specific complex in vitro and have mapped the interacting domains. Molecular genetic data implicate the 1a-2a complex in RNA replication and suggest that it supports coordinate action of the putative helicase, polymerase, and capping domains. The locations of the interacting 1a and 2a domains have implications for replication models and the evolution of virus genomes bearing homologous replication genes in fused vs. divided forms. For the nodavirus Flock house virus (FHV), a true RNA replicase has been isolated that carries out complete, highly active replication of added FHV RNA, producing newly synthesized positive strand RNA in predominantly ssRNA form. Positive strand RNA synthesis in this FHV cell-free system is strongly dependent on the addition of any of several glycerophospholipids. Positive strand RNA synthesis depends on the complete glycerophospholipid structure, including the polar head group and diacyl glycerol lipid portion, and is strongly influenced by acyl chain length.

"Drugs and AIDS--reaching for help": a videotape on AIDS and drug abuse prevention for criminal justice populations.

This article describes the development of a videotape targeted at persons under supervision of the criminal justice system. The videotape seeks to encourage those who use illicit drugs to enter drug treatment and to motivate those at risk for exposure to human immunodeficiency virus (HIV) to alter behaviors that may transmit infection. The criminal justice system presents an important opportunity to deliver such messages, particularly to a large population of persons briefly detained in a jail or lockup and released without subsequent incarceration. Evidence suggests that, even in this audience, knowledge of how to prevent exposure to HIV is widespread, yet those at risk often fail to take appropriate precautions: motivating behavior change demands more than imparting information. In order to shape this videotape, we analyzed the target audience and developed a drama-based approach that applies the framework of social learning theory, the health belief model, and principles of social marketing. This article describes the integration of that theoretical framework into the production process, content, and strategy of the videotape.

Relapse prevention: an emerging technology for promoting long-term drug abstinence.

This article reviews relapse prevention strategies that can be applied after primary drug treatment. To sustain their own recovery, ex-addicts must learn a program of self-management to cope with drug cravings and social pressures to use drugs, become integrated into a new social network, learn to find pleasure in drug-free activities, and find new ways of responding to emotional stress and physical pain. While additional research is needed to identify the very best methods, there is now sufficient evaluation data to argue that practitioners should incorporate this approach as an integral part of their treatment services.

Reducing AIDS and other STDs among inner-city Hispanics: the use of qualitative research in the development of video-based patient education.

We report on the use of qualitative research in the design of video-based interventions aimed at reducing AIDS and other sexually transmitted diseases (STDs) among inner-city Hispanics. Focus groups, personal interviews, and clinic observations were conducted in the South Bronx and Queens, New York, to inform the development of culturally sensitive video-based materials for improving prevention education provided at inner-city STD clinics. Findings elucidate culturally defined gender roles and responsibilities regarding the introduction of condom use into primary and nonprimary relationships, as well as other norms, attitudes, and behaviors reducing the effectiveness of current AIDS and other STD prevention efforts. Too often, educational materials--including an increasing number of videos--are based on untested assumptions about what information should be provided rather than adequate formative research. One reason may be that the literature contains few accounts of how the empirical evidence obtained through such research can be translated into theoretically sound interventions. This paper explicates such a process.

Obesity as a characterological stigma: the issue of responsibility and judgments of task performance.

A study was conducted to investigate whether beliefs about the cause of a person's obesity would influence attributions made about that person's task performance. 168 high school girls were shown a videotape of an obese or normal-weight confederate playing a game and performing either above or below average. Half of the subjects seeing the obese girl were led to believe that her obesity was due to a glandular disorder beyond her control. Subjects rated the obese target as more self-indulgent and less self-disciplined than the normal-weight target, except when her obesity was said to have resulted from a glandular disorder. However, subjects did not differentially attribute the confederate's task performance as a function of her weight or her perceived responsibility for it. Corroborating the results of earlier studies, no evidence was found that these high school girls subscribe to the stereotype of the "jolly" fat person.

Neuropeptides within the nucleus tractus solitarii modulate the central cardiovascular control process.

Local administration of small amounts of vasopressin, angiotensin or endothelin into the nucleus tractus solitarii elicits similar decreases in blood pressure and heart rate. These central effects oppose the peripheral action of these hormones on the cardiovascular system. The baroreceptor-heart-reflex, however, is influenced differentially: vasopressin and angiotensin II enhances the sensitivity of the reflex but angiotensin III impairs it. In this way the cardiovascular system may be adjusted to different demands including those related to electrolyte and fluid homeostasis.

The role of designated driver programs in the prevention of alcohol-impaired driving: a critical reassessment.

We review the "designated driver" concept and the current debate over its role in preventing alcohol-impaired driving. In our view, the focus on this strategy by broadcasters, the alcohol industry, and various public service groups has deflected attention from other alcohol-related problems that account for the vast majority of deaths and injuries associated with alcohol use. This focus has also distracted many public health advocates and policymakers from the bigger and more important jobs of increasing public awareness of the social, environmental, and economic factors that influence alcohol consumption and promoting debate on legislation and other public policy solutions to alcohol-impaired driving. As part of a comprehensive strategy, we strongly encourage a renewed focus on "sobriety checkpoints," strict enforcement of laws against alcohol sales to minors, alcohol advertising reform, increased excise taxes, and other public policy initiatives supported by the Surgeon General. These measures will curb underage and heavy alcohol consumption and will create a legal and social environment in which individuals are motivated to avoid impaired driving through several alternative strategies, including but not limited to the use of designated drivers.

"The responsibility to inform, the power to act": a conference for New England college newspaper editors on the role of the campus press in addressing substance use issues.

College newspapers are a powerful but underutilized medium for educating students on health issues, including those related to drug and alcohol use on campus. Editors of these publications are in a position to wield significant influence among their readers. In addition to communicating factual information about the prevalence and impact of substance use among college students, editors can use the press to advocate changes in students' attitudes and behaviors and in college or community policies that affect substance use. A pilot conference was held to help New England college newspaper editors perceive the importance of their role in educating their peers about substance use and other health-related issues, and to offer concrete suggestions as to how they can incorporate these topics into an "activist" campus press.

A critical analysis of "moderation" advertising sponsored by the beer industry: are "responsible drinking" commercials done responsibly?

This analysis reveals several important advertising trends by the U.S. beer industry, whose purported aim has been to promote "moderation" in drinking. First, the brewers' prevailing interest in promoting consumption has resulted in the use of slogans and messages that ignore the fact that certain people should not drink at all, and, in certain circumstances, that no one should drink. Second, these ads do not consistently make clear that the acts of drinking and driving should remain entirely separate. Third, several aspects of these commercials undermine whatever moderation message they may provide, in particular the use of themes and images that are similar to the beer companies' regular brand promotions. In order to present an acceptable public health message, moderation advertising must not be dominated by glamorous presentations of alcohol consumption. In short, it must be done more responsibly.

Preventing AIDS and other STDs through condom promotion: a patient education intervention.

We report on two studies that assessed the impact of a soap-opera style videotape on inner-city STD (sexually transmitted disease) patients' knowledge about and attitudes toward condom use, and willingness to redeem coupons for free condoms. Subjects in the first study who viewed the videotape (and participated in a brief oral recall session) had higher knowledge scores and more accepting attitudes than subjects who did not (knowledge test means of 11.1 versus 7.9, attitude index means of 13.0 versus 11.3). The intervention was most effective among those who were relatively poorly educated and, to a lesser extent, among those who reported less frequent use of condoms and fewer sex partners. In the second study, intervention group subjects were more likely than control group subjects to redeem coupons. Both groups exhibited a high level of interest in the free condoms. We argue that education and accessibility to free condoms can increase condom use and that health care providers have a vital role in promoting this form of STD prevention.
