Here is a sample paraphrase: From Ron Bachman, "Reaching for the Sky. While the Sears Tower is arguably the greatest achievement in skyscraper engineering so far, it's unlikely that architects and engineers have abandoned the quest for the world's tallest building.
Summary Duringthe Task Force on Community Preventive Services the Task Forcean independent nonfederal task force, conducted a systematic review of scientific evidence regarding the effectiveness of firearms laws in preventing violence, including violent crimes, suicide, and unintentional injury.
The following laws were evaluated: The Task Force found insufficient evidence to determine the effectiveness of any of the firearms laws or combinations of laws reviewed on violent outcomes.
Children and youth today are exposed to a wide range of factors that have been associated with violence not only within the.

Note that insufficient evidence to determine effectiveness should not be interpreted as evidence of ineffectiveness.
This report briefly describes how the reviews were conducted, summarizes the Task Force findings, and provides information regarding needs for future research. Of 28, firearms-related deaths in an average of 79 per day, In the early s, rates of firearms-related homicide, suicide, and unintentional death in the United States exceeded those of 25 other high-income nations i.
In addition, estimates of annual secondhand firearms transactions i. Further, an estimated 0. Thus, the total number of firearms transactions could be as high as 9. Rates of firearm ownership in the United States also exceed those of 14 other nations for which data are available, with the exception of Finland 9.
Of the estimated million firearms owned in the United States at the time of the NSPOF survey, 65 million were handguns; 70 million, rifles; 49 million, shotguns; and the remainder were other guns 7.
Among handgun owners, An estimated 10 million handguns, one sixth of the handguns owned, were regularly carried by their owners, approximately half in the owners' cars and the other half on the owners' persons.
The manufacture, distribution, sale, acquisition, storage, transportation, carrying, and use of firearms in the United States are regulated by a complex array of federal, state, and local Violence in schools research paper and regulations. This review examines firearms laws as one of many approaches to reducing firearms violence 10, This report is one in a series of topics included in the Community Guide, a resource that includes multiple systematic reviews, each focusing on a preventive health topic.
A short overview of the process used by the Task Force to select and review evidence and summarize its findings is included in this report. A full report on the findings and additional evidence including discussions of possible additional benefits, potential harms, existing data problems, research gaps, and directions for future research will be published in the American Journal of Preventive Medicine.
Methods The Community Guide's methods for conducting systematic reviews and linking evidence to recommendations have been described elsewhere In brief, for each Community Guide topic, a multidisciplinary team the systematic review development team conducts a review consisting of the following steps: The group generated a comprehensive list of strategies and created a priority list of interventions for review on the basis of 1 the potential to reduce violence in the U.
The interventions included in this review address several of the objectives outlined in Healthy People 13the disease prevention and health promotion agenda for the United States. Many of the Healthy People objectives outlined in Chapter 15, "Injury and Violence Prevention," relate to firearms laws and their proposed effects on violence-related outcomes Box.
Journal articles, government reports, books, and book chapters were included in this review. Because the purpose of this review was to assess the effectiveness of firearms laws in preventing violence, studies of firearms laws were reviewed only if they assessed at least one violent outcome.
The outcome measures evaluated to determine the effect of each intervention were violent crimes i. Aggravated assault was considered a health-related outcome insofar as it is "an unlawful attack by one person upon another for the purpose of inflicting severe or aggravated bodily injury" 2.
Similarly, robbery was considered a health-related outcome insofar as it is "the taking or attempting to take anything of value from the care, custody, or control of a person or persons by force or threat of force or violence or by putting the victim in fear" 2.
For each of the firearms laws, the team developed an analytic framework indicating possible causal links between that intervention and one or more of the predefined outcomes of interest. Each study meeting the inclusion criteria was evaluated with a standardized abstraction form 14 and was assessed for suitability of study design and threats to validity On the basis of the number of threats to validity, studies were characterized as having good, fair, or limited execution.
Results for each outcome of interest were obtained from each study that met the minimum quality criteria. Measures that were adjusted for the effects of potential confounders were used in preference to crude effect measures.
If two or more studies of a firearms law overlapped in terms of population, time period, and outcomes studied, the systematic review development team chose the study with the fewest execution flaws and the best design to represent effects of the intervention.
A median was calculated as a summary effect measure for each outcome of interest. For bodies of evidence consisting of seven or more studies, an interquartile range was calculated as an index of variability. Unless otherwise noted, the results of each study were represented as a point estimate for the relative change in the violent outcome rate associated with the intervention.
The body of evidence of effectiveness was characterized as strong, sufficient, or insufficient on the basis of the number of available studies, the suitability of study designs for evaluating effectiveness, the quality of execution of the studies, the consistency of the results, and the median effect size The Community Guide uses systematic reviews to evaluate the evidence of intervention effectiveness, and the Task Force makes recommendations based on the findings of these reviews.
The strength of each recommendation is based on the strength of the evidence of effectiveness i. Other types of evidence can also affect a recommendation. For example, evidence that harms from an intervention outweigh improved outcomes might lead to a recommendation against use of the intervention.
If interventions are found to be effective, they are evaluated for cost effectiveness by using economic evaluation guidelines developed for the Community Guide World Health Organization (WHO), London School of Hygiene and Tropical Medicine and South African Medical Research Council, Global and regional estimates of violence against women: prevalence and health effects of intimate partner violence and non-partner sexual violence and Executive summary, WHO, Geneva, , accessed 29 April The Online Writing Lab (OWL) at Purdue University houses writing resources and instructional material, and we provide these as a free service of the Writing Lab at Purdue.

This systematic review examined outcome evaluations of primary prevention strategies for sexual violence perpetration. The review had two goals: 1) to describe and assess the breadth, quality, and evolution of evaluation research in this area; and 2) to summarize the best available research evidence for sexual violence prevention practitioners by categorizing programs with regard to their.
