Despite the importance of critical media work, much is to be learned about breast cancer representations within media discourses and the implications for women’s identity construction. Building on research from Australia from a discursive perspective, this article used an eclectic approach to critical discourse analysis to explore the cultural construction of breast cancer in 25 detailed stories within Canada’s two national newspapers, The Globe and Mail and the National Post. Ten images accompanying stories and 17 advertisements/public service announcements were also analyzed to contextualize discourses and subject positions/identities within the stories. Analysis of this media affords the unique opportunity to explore taken for granted assumptions and prevailing meanings about breast cancer and the implications for subjectivity. Two primary discourses were identified: a discourse of biomedicine and a discourse of healthism. Subject positions identified included “breast cancer survivor,” “the good consumer,” and the “medical expert.” The psychological, social, political, and health promotion implications are discussed.  相似文献

The simultaneous speech of six 4-year-old girls was investigated within three-party conversation. The data reveal two major types of overlap, one providing instances of turn completion projections and the other reflecting tension for the turn at speaking. The data are discussed in terms of the Sacks, Schegloff, and Jefferson (1974) model of conversational interaction.  相似文献

Rodent models have been especially useful for investigating adolescent ethanol exposure. However, there is a paucity of studies examining sex differences in behavioral intoxication from adolescent ethanol drinking. Here, we used an ethanol drinking model to investigate if adolescent rats of both sexes readily drink ethanol to measurable behavioral intoxication, indicated by increased impulsive action and motor incoordination. Beginning on postnatal day (P) 28, male and female Long‐Evans rats were given 30‐min access to a solution of sucrose (20%) or sweetened ethanol (20% sucrose +15% ethanol) every other day until P60 and once after 2 weeks of forced abstinence (on P75). On alternate (nondrinking) days, rats were reinforced with a food pellet for making a cued nosepoke response. Beginning on P56, rats were tested in this task after drinking sessions to assess ethanol‐induced changes in impulsive action, defined as premature responding prior to cue presentation. Motor coordination was assessed before and after drinking sessions using an incline plane test. Adolescent male and female rats readily consumed ethanol to behavioral intoxication, measured as reduced motor coordination. Following forced abstinence, females displayed greater ethanol‐induced impulsive action. These studies provide evidence for sex differences in behavioral intoxication following adolescent ethanol drinking.  相似文献

Tattoos are increasing in popularity, yet minimal research has examined implicit attitudes or the relationship between implicit and explicit attitudes toward tattooed individuals. Seventy-seven online participants (Mage = 36.09, 52% women, 78% white, 26% tattooed) completed measures assessing implicit and explicit attitudes toward tattooed individuals. Results revealed evidence of negative implicit attitudes, which were associated with less perceived warmth, competence, and negative explicit evaluations. However, implicit attitudes were not correlated with measures of disgust or social distance. In addition, age predicted implicit prejudice, but other individual difference measures—such as personal tattoo possession, political identity, and internal/external motivations to respond without prejudice—did not. These findings are discussed in terms of how attitudes toward tattooed individuals may be multifaceted, and research may benefit from measuring implicit and explicit attitudes.  相似文献

Community violence is recognized as a major public health problem (WHO, World Report on Violence and Health, 2002) that Americans increasingly understand has adverse implications beyond inner-cities. However, the majority of research on chronic community violence exposure focuses on ethnic minority, impoverished, and/or crime-ridden communities while treatment and prevention focuses on the perpetrators of the violence, not on the youth who are its direct or indirect victims. School-based treatment and preventive interventions are needed for children at elevated risk for exposure to community violence. In preparation, a longitudinal, community epidemiological study, The Multiple Opportunities to Reach Excellence (MORE) Project, is being fielded to address some of the methodological weaknesses presented in previous studies. This study was designed to better understand the impact of children’s chronic exposure to community violence on their emotional, behavioral, substance use, and academic functioning with an overarching goal to identify malleable risk and protective factors which can be targeted in preventive and intervention programs. This paper describes the MORE Project, its conceptual underpinnings, goals, and methodology, as well as implications for treatment and preventive interventions and future research.  相似文献

This pilot study examined changes in parenting skills and child behavior following participation in an online positive parenting skills program designed for young children with traumatic brain injury (TBI). Thirty-seven families with a child between 3 and 9 years of age who sustained a moderate to severe TBI were randomly assigned to one of two interventions: online parenting skills training (n = 20) or access to Internet resources on managing brain injury (n = 17). Parent–child interaction observations and parent ratings of child behavior were collected pre- and post-treatment. Generalized estimating equations and mixed models were used to examine changes in parenting skills and child behavior problems as well as the moderating role of family income on treatment response. Participants in the parenting skills group displayed significant improvements in observed positive parenting skills relative to participants in the Internet resource group. Income moderated improvements in parent ratings of child behavior, with participants in the low-income parenting skills group and high-income Internet resource group reporting the greatest improvements in behavior. This is the first randomized controlled trial examining online parenting skills training for families of young children with TBI. Improvements in positive parenting skills and child behavior support the utility of this intervention, particularly for families from lower socioeconomic backgrounds.  相似文献

Recent studies demonstrate a requirement for the Extracellular signal Regulated Kinase (ERK) mitogen-activated protein kinase (MAPK) cascade in both the induction of long-lasting forms of hippocampal synaptic plasticity and in hippocampus-dependent associative and spatial learning. In the present studies, we investigated mechanisms by which ERK might contribute to synaptic plasticity at Schaffer collateral synapses in hippocampal slices. We found that long-term potentiation (LTP) induced with a pair of 100-Hz tetani does not require ERK activation in mice whereas it does in rats. However, in mice, inhibition of ERK activation blocked LTP induced by two LTP induction paradigms that mimicked the endogenous θ rhythm. In an additional series of studies, we found that mice specifically deficient in the ERK1 isoform of MAPK showed no impairments in tests of hippocampal physiology. To investigate ERK-dependent mechanisms operating during LTP-inducing stimulation paradigms, we monitored spike production in the cell body layer of the hippocampus during the period of θ-like LTP-inducing stimulation. θ-burst stimulation (TBS) produced a significant amount of postsynaptic spiking, and the likelihood of spike production increased progressively over the course of the three trains of TBS independent of any apparent increase in Excitatory Post-Synaptic Potential (EPSP) magnitude. Inhibition of ERK activation dampened this TBS-associated increase in spiking. These data indicate that, for specific patterns of stimulation, ERK may function in the regulation of neuronal excitability in hippocampal area CA1. Overall, our data indicate that the progressive increase in spiking observed during TBS represents a form of physiologic temporal integration that is dependent on ERK MAPK activity.  相似文献

Although there has been considerable interest in the effects of errors on subsequent performance, relatively few studies have considered the effects of non-error events that contain some performance-relevant information, such as correct performance on critical trials. In the present article, we propose and assess a hypothesis of performance reactivity. In support of this hypothesis, we provide evidence of performance decrements following both incorrect and correct responses but not following performance-irrelevant events. More specifically, in a continuous response task (Sustained Attention to Response Task), we (1) replicate previous findings that errors of commission on rare NOGO trials produce decrements in subsequent performance, and (2) observe that correct withholds to NOGO trials produce decrements in subsequent accuracy relative to task-irrelevant tones. These results corroborate a hypothesis that some error-related effects on subsequent performance are not unique, but are instead a particularly salient version of a more general performance-reactivity effect.  相似文献
