Via telephone, a national probability sample of 1464 respondents randomly received one of three question versions of a voter turnout question in the months of December, January, and February, following the November 1998 Congressional elections in the United States. The long version form contained memory cueing techniques and face-saving response options, the short form, modeled after the 2000 American National Election Studies (ANES) question, included only the face-saving response options, and the standard form, modeled after ANES questions used before 2000, included neither. The long form led to significantly lower reported turnout in comparison to both the short and standard forms, indicating that the long form successfully reduced vote overreporting in comparison to the other question versions.  相似文献

This study examines the relationship between vulnerability factors and recidivism by testing the hypothesis that first offenders who repeat delinquencies display more high-risk factors than those who do not repeat delinquencies. Four factors are identified which distinguish recidivists from nonrecidivists in a sample of first offenders matched by age and sex. Results are discussed from an epidemiological and early-intervention perspective.Data collected in 1980 were supported by the Research Associates, Clarke Institute of Psychiatry, University of Toronto, Toronto, Ontario, Canada.Received MSW from University of Michigan, 1972. Major research interests are juvenile delinquency and early intervention.Received Ph.D. in psychology from Washington University, St. Louis, Missouri, 1957.

Research interests are cognitive development and mental health-care delivery.  相似文献

Objectives

Prospective person memory refers to situations where one is asked to be on the lookout for a missing or wanted individual. Some researchers have hypothesized that because people see missing person alerts for multiple people over a period of time, that people habituate to missing persons alerts much like they do to car alarms. The purpose of this research was to test that hypothesis.

Methods

Some participants saw three different mock missing person videos, depicting three different target individuals, with one video being shown on each of 3 days (Monday, Wednesday, Friday). Other participants engaged in unrelated tasks on the first 2 days and saw a single mock missing person video on the third day. All participants were told that if they saw a person from a mock missing person video and contacted the experimenters they would win a cash prize. On the final day of the study, the target individual was located in the hallway a short distance from the experiment room in a location that participants had to pass on their way out of the building.

Results

Correct sightings of the target individual were significantly lower in the multiple video condition than in the single video condition.

Conclusions

The results suggest that overuse of missing person alert systems can decrease their effectiveness in a manner consistent with a “car alarm” effect.

The Conservative party spent £1.2 million on Facebook during the UK 2015 general election campaign. This enabled the party to target specific voters in marginal constituencies with tailored messages. Their use of Facebook in 2015 shows how central digital media had become to their campaign communication. It also shows, however, that this communication may be compromising the principles of fair and open elections in the UK, for example by allowing parties to effectively bypass constituency spending limits and avoid transparency. Unless electoral legislation and regulation are changed to take account of developments in digital media they are liable to become increasingly anachronistic and ineffective.  相似文献

This article conceptualizes what strict liability is in the criminal law. Four properties are found to be individually necessary, only jointly sufficient, for there to be the kind of moral blameworthiness that must underlie any just punishment: prima facie wrongdoing, absence of justification, prima facie culpability, and absence of excuse. Whenever criminal liability is imposed without the presence of one or more of these properties, the liabuility is said to be strict.  相似文献

Although homeless youth face a higher risk of victimization and mental health problems, little is known about school victimization and mental health outcomes for school-attending homeless youth. This study examined the relationship between school climate and school-related victimization and mental health problems among homeless youth. Multivariate analyses were conducted to examine the relationship between school climate factors and school victimization, suicidal ideation, and depression tendency in a representative sample of 1,169 school-attending homeless youth in 9th and 11th grades in California. Findings show that school-attending homeless youth are at high risk of being victimized at school and have high rates of depression tendency and suicidal ideation. Positive school climate, especially perceived high expectations from teachers and safety in school, was associated with lower rates of school victimization and mental health problems. The role of supportive school climate in the lives of school-attending homeless youth is discussed and future implications are suggested.  相似文献
