Crises of confidence have plagued the American presidency since the introduction of television into the political sphere. Recognizing from previous research that unpopular incumbents use rhetoric in an effort to regain their credibility, this study looks at these rhetorical choices to see how they constrain or provide opportunities for the incumbent party's successors. Specifically, the study looks at the rhetoric surrounding instances where presidents have dropped 20 points in Gallup approval ratings within the last two years of their terms. The study reveals that an unpopular incumbent's interest in regaining the public's faith is frequently at odds with his successor's interests. Incumbents need to remove themselves as the cause of the crisis, convince the public that they have the solution to the problem, and bide enough time to affect the situation. These choices tend to constrain the simplicity, flexibility, and timeliness of the successor's choices for rhetorically resolving the crises. 相似文献

Contemporary writing about girlhood is often gloomy in tone. Girls are represented as the victims of all manner of social trends: capitalism, consumerism, body obsessions, ‘sexualisation’, pornography, etc. Or girls themselves come under attack for bad behaviour, as ‘ladettes’ or ‘living dolls’. But in some parts of the world at least, young women enjoy more freedom and opportunities than ever before. Looking back over her own lifetime, the author argues that feminism has been a potent force for betterment—a belief that things can and do sometimes improve serves to sustain political projects. 相似文献

An extremely sensitive species-specific ARMS PCR test for the presence of tiger bone DNA 总被引:7,自引:0,他引:7
The survival of the tiger (Panthera tigris) is seriously threatened by poaching to provide raw materials for traditional Chinese medicines (TCMs). Most highly prized are the tiger's bones, which are used in combination with other animal and plant derivatives in pills and plasters for the treatment of rheumatism and other ailments. Hundreds of patent remedies have been produced which claim to contain tiger bone, but proof of its presence is needed if legislation prohibiting the trade in endangered species is to be enforced.A highly sensitive tiger-specific real-time PCR assay has been developed to address this problem. Using primers specific to the tiger mitochondrial cytochrome b gene, successful amplification has been reliably achieved from blood, hair and bone as well as from a range of TCMs spiked with 0.5% tiger bone. Although capable of detecting fewer than 10 substrate molecules, the seven varieties of TCM pills and plasters tested showed no detectable trace of tiger DNA before spiking. Furthermore, sequencing several "tiger bone" fragments seized from TCM shops has shown that they actually originated from cattle and pigs. The potential effects of traditional bone preparation methods, evidence that much lower concentrations are used than alleged on TCM packaging, and substitution of bones from other species all suggest a low likelihood of detecting tiger DNA in patent medicines. Despite this, the basic methods have been thoroughly proven and can be readily applied to derivatives from other Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) protected species, providing a rapid and highly sensitive forensic test for species of origin. Potential applications to the monitoring of wild populations are demonstrated by the successful identification of shed hairs and faecal samples. 相似文献

This article reviews the major forms of violence against women, including sexual assault, intimate-relationship violence, and stalking and outlines the known psychological effects of such victimization. Also discussed are a number of variables that combine to determine the effects of such victimization, including type and characteristics of the assault; victim variables such as demographics, psychological reactions at the time of the trauma, previous victimization history, current or previous psychological difficulties, and general coping style; and sociocultural factors such as poverty, social inequality, and inadequate social support. The implications of this complexity are explored in terms of psychological assessment and the frequent need for multitarget, multimodal treatment approaches. 相似文献

An underexamined component of Erik Erikson's psychosocial theory is the concept of ego strengths. The eight ego strengths are present throughout the life span, but each have their ascendance in conjunction with successful psychosocial stage resolutions. Upon careful analysis of Erikson's writings, the Psychosocial Inventory of Ego Strengths (PIES) was developed to assess this component of psychosocial theory. The measure was scrutinized by several Eriksonian scholars for its face and content validity. Then, two studies were conducted among college samples in the United States and Canada. Evidence for internal consistency was shown for the eight ego strengths, as well as on overall score. Convergent validity was shown between the PIES and assessments of identity achievement, self-esteem, purpose in life, internal locus of control, and sex roles. Discriminant validity was observed in negative correlations between the ego strengths and hopelessness, identity diffusion, identity moratorium, and personal distress. Suggestions for future research utilizing this measure are given. 相似文献

Federalism was a major political issue in 1995 and 1996 withpresidential candidates, congressional leaders, governors, andthe courts weighing in with proposals to shift responsibilityfrom Washington to states and localities. There was more talkthan action, but as the second session of the 104th Congresswound down in the late summer, a major proposal to block grantthe 61-year old Aid to Families with Dependent Children programwas enacted. This enactment allowed both Democrats and Republicansto take political credit, and gave major responsibilities tothe states to implement the new approach to a former entitlementprogram. Five themes characterized the year: (1) federalismwas once again a salient issue; (2) deficit reduction and devolutionwere bound together; (3) the U.S. Supreme Court continued toreexamine and possibly redefine the legal parameters of federalism;(4) state officials became more visible political actors inWashington, D. C.; and (5) states provided key policy and managementleadership. 相似文献

This review specifically addresses the effects on children of observing conjugal violence. A research of six major computer databases revealed 1764 references on family violence of which 29 articles dealt directly with the effects on children. These articles were judged by independent raters using a 56-item rating system designed to analyze methodological and assessment issues of empirical investigations. This analysis summarized these research efforts and indicated the need for more careful consideration of definitional, subject variable, familial stress, and reactive vs long-term effect issues. Additionally, specific proposals for future research were outlined; suggestions related to these issues, and some new directions for investigation were provided. 相似文献

In order to make greater use of dog hairs as forensic evidence, we have developed a robust method for duplex amplification of adjacent 306 and 332bp amplicons within the 5' hypervariable region (5' HVR) of the canine mitochondrial control region. In support of this, a 595bp region covering 35 polymorphic sites has been sequenced from the blood of 105 UK dogs. In total, 30 different haplotypes were observed, 13 only once whilst the commonest was seen 14 times; the overall exclusion capacity is 0.929. One animal was heteroplasmic in blood for a single base deletion and showed phenotypes ranging from near complete deletion to a predominance of the base among a sample of 12 hairs. In contrast, no evidence of heteroplasmy was seen in single hairs from 20 dogs which were not visibly heteroplasmic in blood. Phylogenetic analysis and comparisons with other published databases highlighted instances of possible recurrent mutation which may be relevant when interpreting single base differences between samples. 相似文献
