The public's willingness to discuss their preference for organ donation with family members.

We sought to assess the public's willingness to discuss their preference for organ donation with family members and to identify factors associated with willingness to discuss donation. We categorized individuals (N = 4365) with a preference for donation according to their willingness to discuss donation and used ordinal logistic regression analysis to identify factors related to their level of willingness. About half of those who want to donate have discussed this with a family member. Others were at various stages with respect to their commitment to discuss donation. Those in the more committed stages were more likely than others to have signed an organ donor card, to have seen information about organ donation, to be male, to be white or Hispanic, to know about donation issues, and to be comfortable with the idea of their own death. The decision to donate is ultimately made by family members of a suitable candidate for donation, yet nearly half of those who wish to donate have not made their wishes known. Interventions targeted to individuals at different stages of commitment are needed so that more family members can respond in accordance with their loved one's wishes.

The use of designated drivers by US college students: a national study.

A representative national sample of students attending 4-year colleges in the United States reported whether they had served as or had ridden with a designated driver in the past 30 days and how much alcohol they had consumed the last time they used this prevention strategy. Among drinkers (those who had consumed alcohol in the past year), 36% said they had served as a designated driver in the past 30 days; of these, 40% said they usually binged when they drank but had not done so the last time they served as the designated driver, with the vast majority either abstaining or having 1 drink. Among drinkers, 37% reported riding with a designated driver in the past 30 days; of these, 22% said they did not usually binge but did so the last time they had a designated driver because they had had 1 or more extra drinks. Among college students, using designated drivers is now a well-established strategy for avoiding impaired driving.

Rape and physical attractiveness: judgments concerning likelihood of victimization.

Subjects in two studies were shown portraits of 32 young women who varied widely in physical attractiveness. Subjects were told that half of these women had been victims of a crime and half had not. Their job was to sort the portraits correctly into those two categories. In both studies, attractive women were more often categorized as victims of rape. In Study 2, attractive women were not more likely to be categorized as having been beaten and robbed. Correlation analyses showed that the association between physical attractiveness and presumed criminal victimization was significantly higher for rape than for being beaten and robbed.

Strategies to reduce driving under the influence of alcohol.

The purpose of this review is to update research on the prevention of alcohol-related traffic deaths since the 1988 Surgeon General's Workshop on Drunk Driving. Four primary areas of research are reviewed here: (a) general deterrence policies, (b) alcohol control policies, (c) mass communications campaigns, including advertising restrictions, and (d) community traffic safety programs. Modern efforts to combat drunk driving in the United States began with specific deterrence strategies to punish convicted drunk drivers, and then evolved to include general deterrence strategies that were targeted to the population as a whole. Efforts next expanded to include the alcohol side of the problem, with measures installed to decrease underage drinking and excessive alcohol consumption. In the next several years, greater efforts are needed on all these fronts. Also needed, however, are programs that integrate drunk driving prevention with other traffic safety initiatives.

Requesting organ donation: an interview study of donor and nondonor families.

BACKGROUND: Approximately half of the families asked to consider donation of a relative's organs decline to give consent. Understanding the difference between stated public support of organ donation and actual behavior is key to decreasing the shortage of donor organs. OBJECTIVES: To gain insight into the experiences of potential donor families and to define features of the donation-request process and other factors that are associated with consent for organ donation. METHODS: A structured telephone interview was conducted with the immediate next of kin of 164 medically suitable potential organ donors. Interviews 30 to 60 minutes long were held with members of both donor and nondonor families 4 to 6 months after the death of the study participant's relative. RESULTS: Several factors were associated with consent for organ donation: characteristics of the patient and the patient's family, beliefs and attitudes about organ donation and transplantation, whether the family knew the deceased's wishes about donation, the family's satisfaction with the hospital care that their relative received, specific aspects of the donation-request process, and the family's understanding of brain death. CONCLUSIONS: Organ donation rates could be increased by enhancing the quality of hospital care and ensuring that the request for donation is handled in a way that meets the families' informational and emotional needs.

Does cigarette print advertising adhere to the Tobacco Institute's voluntary advertising and promotion code? An assessment.

OBJECTIVES: This investigation examined whether, despite the Tobacco Institute's Voluntary Cigarette Advertising and Promotion Code, current cigarette print advertising communicates culturally positive messages to youth about smoking. METHODS: Nine hundred thirteen students in grades 6-8 (ages 10-15) were shown a sample of four contemporary cigarette print ads (Camel, Marlboro, Newport, and Virginia Slims) and completed structured written assessments designed to capture their perceptions of each ad. RESULTS: Across the four ads, between 37% and 84% of the students reported that the ads communicated to them that smoking will make people popular, cool, successful in life, sexy, attractive, and healthy. Sizeable percentages of students reported that the ads show people using the product in an "exaggerated" way, and that what people in the ads are doing requires "exercise and physical energy." The median estimated age of the models in the ads was under age 25 for four out of the six models. CONCLUSIONS: As perceived by adolescents, current cigarette print advertising violates basic tenets of the Voluntary Code, thus bringing into question the tobacco industry's ability to self-regulate image advertising. These findings suggest that the FDA ruling to prohibit image advertising for tobacco in publications with significant youth readership deserves serious consideration.

Explaining brain death: a critical feature of the donation process.

To examine how a family's understanding of brain death may affect the decision to donate, an interview study was conducted with the immediate next of kin of 164 medically suitable organ donor candidates. Telephone interviews were conducted with members of both donor and nondonor families 4 to 6 months after the relative's death. Only 61% of the donor and 53% of the nondonor respondents said they had received an explanation of brain death. Few respondents reported that the hospital or organ procurement organization staff used visual aids to clarify or reinforce the information they were given. Next of kin who decided against donation had far less understanding of brain death than did those who decided in favor of it. Before making an organ donation request, healthcare providers must inquire about and address common misunderstandings people have about brain death. Healthcare teams should develop and be trained on a clear protocol for communicating with the families of patients who may be potential organ donors.

When the tobacco industry controls the news: KKR, RJR Nabisco, and the Weekly Reader Corporation.

BACKGROUND: The Weekly Reader Corporation was acquired in 1991 by K-III Communications, whose majority shareholder is Kohlberg Kravis Roberts & Co. (KKR), best known for its leveraged buyout of tobacco conglomerate RJR Nabisco. Among other student newspapers, Weekly Reader publishes Current Events for students in grades 6-10 (ages 11-16). OBJECTIVE: To explore how KKR's ownership might have affected the content of tobacco-related news stories in Current Events, which reaches students at the very ages when many begin to experiment with tobacco. METHODS: A content analysis was conducted of 182 issues of Current Events, 71 pre-acquisition and 111 post-acquisition. Tobacco-related news was reported in four articles in the pre-acquisition issues and in 12 articles in the post-acquisition issues. RESULTS: The content of tobacco-related news stories shifted after KKR's acquisition to portray tobacco as a "forbidden fruit" that is attractive to teenagers. This was done by focusing on new policies and programmes to discourage teenagers from smoking, the mythical threat of prohibition, and the supposed popularity of smoking, while giving relatively little attention to the health consequences of tobacco use. CONCLUSIONS: After engineering a stock swap with Bordens in 1995, KKR no longer directly owns RJR Nabisco stock. This case study underscores the need for public health advocates to be watchful of the tobacco industry's efforts to control public access to news about tobacco.

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.
