Campaigns are an interactive process in which candidates, outside groups, the media, and voters communicate with each other to create an information environment that allows the various participants to construct meaning and form an understanding of the candidates and the campaign. Presidential primaries add a layer of complexity to this process as candidates and the press deal with both local and national audiences. In this article, we analyze the campaign communications in the 2000 Republican presidential primary in South Carolina—including candidate ads, mailings, and phone calls; local and national newspaper coverage; and network television coverage. We find that there was a disconnect as news media often focused on events and issues that diverged from the messages of the candidates' campaigns. In addition, we find substantial differences between local and national media coverage of the primary resulting from their distinct audiences and the reporters' own understanding of the local context that created significantly different information environments for voters in the state and those out of the state. We consider the implications of these findings for how voters and journalists understand the candidates as well as the challenges presidential candidates face in simultaneously campaigning locally and nationally.  相似文献

Evidence supports the use of acceptance and commitment therapy (ACT) for well-being and behavior change among parents. This study examined the impact of a brief ACT intervention on positive parenting strategies, psychological flexibility, and distress among parents who have experienced relationship violence.As part of a larger study, 43 parents were recruited from a community outreach center and completed measures of parenting, ACT processes, and distress. Participants were pseudo-randomly assigned to either receive their treatment-as-usual (TAU) or ACT plus TAU. Twenty-five participants received four weekly sessions of ACT plus TAU, and 18 received TAU only. Positive parenting behaviors among parents in the ACT?+?TAU group improved immediately following treatment compared to the TAU group. Improvements were maintained six weeks following treatment. The hypothesis that psychological flexibility would mediate improvements was not supported.The present study provides initial, preliminary support for the secondary benefits of brief, broad ACT interventions for positive parenting behaviors among parents who have experienced relationship violence. Clinical implications for implementing ACT for parents who have experienced relationship violence and methodological limitations are discussed.  相似文献

As interest in registered sex offenders proves to be a popular topic among community members, the media, and legislators alike, researchers must continue to examine the experiences of this offender group. Sex offender registration and community notification laws are diverse across states, creating a difficult and confusing environment for registered sex offenders post-conviction. Often, registered sex offenders report experiences with social stigmatization and physical isolation from their communities as a result of their labeled status. This leads them to be distrustful of outsiders; researchers included. This paper examines the experiences of researchers who have conducted three quantitative and qualitative research projects focused on registered sex offenders and life on the registry. In addition to highlighting the challenges in conducting this type of research, this paper provides a discussion of four specific challenges that may occur when gathering data from community sex offender samples, and several recommendations to overcome these challenges.  相似文献

Abstract: The forensic sciences are under review more so than ever before. Such review is necessary and healthy and should be a continuous process. It identifies areas for improvement in quality practices and services. The issues surrounding error, i.e., measurement error, human error, contextual bias, and confirmatory bias, and interpretation are discussed. Infrastructure is already in place to support reliability. However, more definition and clarity of terms and interpretation would facilitate communication and understanding. Material improvement across the disciplines should be sought through national programs in education and training, focused on science, the scientific method, statistics, and ethics. To provide direction for advancing the forensic sciences a list of recommendations ranging from further documentation to new research and validation to education and to accreditation is provided for consideration. The list is a starting point for discussion that could foster further thought and input in developing an overarching strategic plan for enhancing the forensic sciences.  相似文献

This research partially tests Akers’ social structure-social learning theory (SSSL). The data was collected online through a self-report questionnaire and nearly half (48.8%) of the sample of 812 college students reported visiting a porn site. To better understand this self-report behavior, bivariate correlations and three binary logistic regression analyses were conducted. In Model A, participants who were male, Hispanic, had more years in college, and more inclined toward homosexuality had an increased likelihood of visiting a porn site. In Model B, again, gender, ethnicity, year in school, and the sexuality scale were significant predictors. However, race appeared as significant for the first time along with number of sex partners, and frequency of masturbation, indicating that participants who were Black, had a greater number of sexual partners, and masturbated more frequently had an increased likelihood of visiting porn site. As with the first and second models, gender, race, sexuality scale, and frequency of masturbation were significant predictors in Model C. Additionally, differential peer association, differential reinforcement, and definitions favorable were significant, indicating that participants who had greater association with peers who viewed porn, who had observed someone watching porn and decided to mimic their behaviors, and who had defined visiting porn sites favorably had an increased likelihood of visiting a porn site. Overall, Akers’ SLT variables fully mediated ethnicity, year in school, and number of sex partners, but it only partially mediated gender, race, and sexuality scale.  相似文献

Résumé Cet article constitue une proposition théorique et méthodologique afin d'étudier les conditions menant à la mise en oeuvre du droit et, plus particulièrement, au déclenchement du processus pénal dans des situations concrètes. En utilisant de nombreux travaux empiriques et théoriques, les auteurs ont privilégié trois dimensions analytiques. Premièrement, les déterminants susceptibles d'affecter la mise en oeuvre du système pénal seront examinées. En deuxième lieu, une attention particulièrement sera accordée à l'identité des renvoyants. Enfin, les motifs à l'origine de la décision de renvoyer une affaire vers le système pénal seront discutés.   相似文献

In criminal justice, researchers have identified disenfranchised grief, or the denial of empathy and social support during the grieving process, in family members who have lost relatives through imprisonment and execution. Although both of these situations involve the physical removal of the offender from the family members’ lives, non-physical losses may also prompt the grieving process. One of these non-physical losses is a psychosocial loss, in which the person the family members knew is now gone. Given the public stigma of the label “sex offender” and the collateral consequences that occur as a result of that label, it is possible that sex offender significant others experience a psychosocial loss. The current research is an exploratory study that used qualitative interviews with 29 spouses and significant others of convicted sex offenders to explore if and how disenfranchised grief impacts sex offender partners. Findings support both the existence of and the detrimental impact of disenfranchised grief on sex offender partners.  相似文献

Online vendors are offering a new legal high, 4‐methylpentedrone (4‐MPD). Information for potential users provided by internet vendors of 4‐MPD includes incorrect structures and nonexistent CAS numbers. A sample of 4‐MPD was obtained and analyzed using GC‐MS, NMR, and LC‐EIS. The fragmentation data from the GC‐MS and LC‐EIS produced an M‐1 ion that suggested the molecular mass was 219 amu, rather than 205 amu as calculated for 4‐methylpentedrone. The difference in molecular mass corresponded to the addition of a methyl group. Based on the mass and fragmentation pattern, two standards were synthesized, 2‐(ethylamino)‐1‐(4‐methylphenyl)‐1‐pentanone and 1‐(4‐methylphenyl)‐2‐(propylamino)‐1‐butanone. The synthesis involved bromination of the appropriate ketone followed by the reaction with ethylamine or propylamine. Based on the NMR data and unique fragmentation patterns produced by these molecules, the sample was identified as 2‐(ethylamino)‐1‐(4‐methylphenyl)‐1‐pentanone, not 4‐methylpentedrone.  相似文献
