Conventional wisdom and scholarly research indicate that to win a policy debate political actors should frame the issue strategically—that is, selectively highlight considerations that mobilize public opinion behind their policy position. Engaging the opponent in a dialogue (i.e., focusing on the same considerations) is portrayed as a suboptimal strategy because political actors forfeit the ability to structure the debate. Using over 40 public opinion polls and a detailed content analysis of news stories, I examine the use of framing and engagement strategies during the 1993–94 debate over health care reform. The analysis shows that engagement was more effective at increasing support for reform than framing. This study is the first to document the role of engagement in a policy debate, and it extends work showing that this strategy is more common in election campaigns than scholars once suspected.

ABSTRACT

This study examined the factors that influence support for campus carry laws among a sample of approximately 2,700 faculty/administrators, staff, and students at a large, public university in Georgia. Although previous research suggests that support for campus carry may differ across groups on campus, there have been no studies that have examined why these differences may exist. In order to shed light on this understudied issue, this study estimated the extent of support for campus carry and examined if the predictors of support varied across campus populations. Results indicated that there were differences in the proportion of each group that supported campus carry with students (57%) reporting a higher level of support than staff (39%) and faculty/administrators (19%). Further, results from multivariate analyses indicated that there are some differences in the factors that predict support for campus carry for faculty/administrators compared to staff and students.  相似文献

From a forensic perspective, a presumptive test, one which indicates the presence or absence of a certain target material such as blood, is an invaluable tool. Among these tests, there are different specificities, sensitivities, and shelf lives. The accuracy of a test is an algebraic combination of the specificity and sensitivity of the test. Each test has limitations as given by its false positive and false negative rates. The aim of this study was to illustrate how the false positive and false negative rates are to be properly determined using a simulation study for the phenolphthalein test. New presumptive tests must be properly evaluated/validated through testing of commonly encountered household items and other potentially probative items usually found at crime scenes, however, the makeup of test sets must appropriately capture all error rates. In order to correctly use these results when the test is applied to an unknown sample recovered at a crime scene, the error rates cannot be applied directly to estimate whether or not the sample is actually the analyte of interest. In a validation study, the forensic scientist calculates the false positive rate as the p(Positive Reaction|Blood), whereas at the scene, the crime scene investigator wishes to determine the p(Blood|Positive Reaction). All crime scene investigators need to ensure that the conditional is not transposed when interpreting such results. Furthermore, this work provides a model for the assessment of a multiple test diagnostic system intended for investigators.  相似文献

Since the mid‐1990s, the federal government has funded numerous relationship skills programs, including some specifically targeting low‐income, unmarried parents, in an effort to strengthen couples’ relationships and increase family stability. The previous research on the effectiveness of these interventions has revealed mixed results about whether such programs can improve the relationships of lower income couples who tend to experience lower relationship quality, lower marriage rates, and higher rates of relationship dissolution. This article draws on in‐depth qualitative data collected during an 18‐month ethnographic study of one federally funded relationship skills program for unmarried, low‐income couples expecting a new baby. Overall, though parents found the financial management lessons included in the classes only minimally useful, if at all, they found other aspects of the program particularly useful for three main reasons: (1) classes allowed parents to focus exclusively on their couple relationships in ways they rarely did otherwise; (2) program incentives helped parents make financial ends meet that month; and (3) parents learned that the challenges they personally experienced were often endemic to the romantic and co‐parenting relationships of unmarried parents who have few resources and experience more challenges that tend to undermine relationship quality, such as financial stress and relational ambiguity. Engaging with other couples around shared challenges normalized couples’ relationship problems and lessened the resentment and animosity that typically characterized their partner interactions. These findings have important implications for healthy marriage and relationship policy. Program developers should avoid lessons that imply low‐income, unmarried parents’ spending habits and family‐formation decisions are deficient. Interventions should instead encourage couples to discuss their shared challenges and minimize their tendency to individualize relational and financial strain.  相似文献

Over the last several decades, Gallup data shows an increased willingness among members of the public to support presidential candidates from a wide range of religious backgrounds, though a nontrivial proportion of the public is still unwilling to vote for an Atheist, Mormon, or Muslim. What underlies this opposition? We argue that voters evaluate candidates from religious out-groups more negatively on a wide range of dimensions considered desirable for political office, and that this bias should be more pronounced among the highly religious. We show support for these arguments using a survey experiment fielded with YouGov. Atheists and Muslim candidates were perceived more negatively on a large set of traits considered desirable for political office compared to candidates from religious in-groups, and Mormon candidates fall somewhere in between. The Atheist and Muslim candidates were also perceived as less competent on a diverse set of issues.

“Bullet wipe” is the material deposited by a bullet on any surface with which it comes into contact after it is fired and may contain debris from the gun barrel, including particles of primer and metal fragments from previously fired bullets. X‐ray analysis is a non‐destructive method by which traces of metallic elements can be visually detected. The analysis of osseous defects for radiodense bullet wipe (RBW) assists in determining the presence or absence of perforating gunshot wounds, especially in fragmented, skeletonized remains. The aim of our current study was to determine the frequency of RBW around entrance firearms injuries that perforated bone. We prospectively analyzed entrance gunshot wounds for RBW over a three‐year period using digital X‐ray analysis (n = 59). We retrospectively reviewed the corresponding autopsy reports to determine the frequency of RBW by biologic sex, reported ancestry, age‐at‐death, location of wound, manner of death, range of fire, bullet caliber, and presence of bullet jacket. Data were analyzed by Fisher's exact test or Chi‐square test with significance levels accepted at p < 0.05. RBW was present in 66% (n = 39) of examined cases. Decedent characteristics did not significantly alter RBW distribution, including biologic sex (p = 0.75), reported ancestry (p = 0.49), and age‐at‐death (p = 0.43). Additionally, the location of the osseous entrance gunshot wound, manner of death, range of fire, and cartridge caliber did not affect RBW detection. All cases involving non‐jacketed rounds (n = 5) showed RBW (p = 0.30). To our knowledge, this study is the first to report the frequency of RBW detection from osseous entrance gunshot wounds.  相似文献
