Previous content analyses of sex on television have relied on differing measures and sampling strategies, which makes it difficult to compare patterns of sexual portrayals over time. This large-scale study (N = 2,817 programs) examines the sexual messages presented on television across both broadcast and cable channels over a 5-year period, applying identical measures to three biennial samples of program content. Results demonstrate that sexual talk and behavior are highly frequent aspects of the television environment. Talk about sex is shown more often than sexual behavior, though both types of content increased significantly from 1997/1998 to 2001/2002. Over that time span, the percentage of shows portraying sexual intercourse doubled from 7 to 14%. Results also show that topics related to sexual risks or responsibilities (e.g., condom use, abstinence) are increasingly included on television, but nonetheless remain infrequent overall. Such safe sex messages occur most frequently in program environments where they are most relevant (i.e., when sexual intercourse is included in the story). The content analysis findings are discussed in terms of their implications for audience effects.  相似文献

This study examines the effect of primary and secondary control on 3 major outcomes experienced by visually impaired older adults, that is, functional ability, adaptation to vision loss, and positive affect. The authors' theoretical model is based on the J. Heckhausen and R. Schulz (1995) control framework, as well as a conceptual integration of these outcomes, and they hypothesized that control beliefs can substantially contribute to explaining interindividual differences in these outcomes. A path model applied to data from a sample (N = 90) of visually impaired older adults, suffering from age-related macular degeneration, the major cause of vision loss in old age, generally supports this expectation.  相似文献

Little has been reported regarding how women make decisions about genetic carrier screening for Ashkenazi Jewish genetic disease and cystic fibrosis (CF), and for fluorescent in situ hybridization (FISH) during pregnancy. Thirty-seven women who underwent genetic counseling and prenatal diagnosis were interviewed about their prenatal decision making. Respondents were largely Caucasian (95%), and undergoing prenatal diagnosis because of maternal age (78%). Sixty-three percent of those who reported having genetic carrier screening correctly defined it; 83% felt positively about it. Primary reasons reported for electing screening were: to get information, to be prepared, perception of risk, wanting peace of mind and percieved inability to care for an affected child. Women who declined screening felt they had very little or no risk, and some were deterred by cost. Ninety-five percent of respondents elected to have FISH; most were motivated by its speed in providing information and peace of mind or by timing of when the procedure was performed. Those who declined FISH reported being less concerned about having an affected child, receiving bad news, or waiting 2 weeks for results and slightly less affected by their feelings toward medical testing or physician's suggestion. These findings suggest decision-making factors differ between those electing and declining adjunct prenatal testing and increased knowledge about these factors may impact the way in which these services are offered by health care professionals. Prospective research with a larger population will be useful in further delineating the factors that influence prenatal decisions about adjunct testing measures.  相似文献

Previous research has shown that separate information sources, activated closely together in time, can induce errors suggestive of memory blends. In Experiment 1, homophones were used to induce such memory errors. In a study task, participants made relatedness judgments to word pairs that included homophones (e.g., PAWS-BEAR). During this task, one group (study-similar) maintained memory loads with words that were orthographically similar to the presented homophones (e.g., JAWS). Another group (test-similar) maintained memory loads similar to those obtained for the study homophone's alternate spelling (e.g., CAUSE). A third group maintained no memory load during the task. In a surprise recognition test, participants were presented both previously viewed homophones (PAWS) and non-presented alternate spellings (PAUSE). We hypothesized that partially activated alternate spellings, in conjunction with the orthographically similar memory words, would result in the creation of blended memories. The results followed suit: The test-similar condition produced significantly elevated false alarms, relative to both the study-similar and the no-load conditions. Experiment 2 replicated these results while including memory loads to control for potential orthographic confusions. The findings are discussed in terms of multiple, episodic memories later activated as single, blended memories.  相似文献

We used the Rasch (1980) model to develop new pictures for the Thematic Apperception Test (C. D. Morgan & Murray, 1938; McClelland, Atkinson, Clark, & Lowell, 1953) or picture story exercise to measure need for achievement (nAch). In Experiments 1 and 2, we analyzed stories to assess the difficulty level of a total of 8 pictures using the multifaceted Rasch model with picture difficulty, story probe difficulty, and participant ability as facets with a partial credit model (FACETS; Linacre, 2005). A total of 6 pictures were retained and 4 new ones added for Experiment 3 in which 201 participants wrote 6 stories to a random set of the 10 pictures. FACETS analysis revealed improved person separation reliability. In Experiment 4, 206 participants wrote 1 story to the Studying picture either before or after filling out a battery of achievement-related questionnaires. The 2 experimental groups did not differ in the amount of nAch in their stories. The coder facet was demonstrated with 2 independent coders using the revised coding system for nAch.  相似文献

Evidence-based medicine has been defined as the conscientious and judicious use of current best evidence in making clinical decisions. This paper will attempt to explicate the terms "conscientious" and "judicious" within the evidence-based medicine definition. It will be argued that "conscientious" and "judicious" represent virtue terms derived from virtue ethics and virtue epistemology. The identification of explicit virtue components in the definition and therefore conception of evidence-based medicine presents an important starting point in the connection between virtue theories and medicine itself. In addition, a unification of virtue theories and evidence-based medicine will illustrate the need for future research in order to combine the fields of virtue-based approaches and clinical practice.  相似文献

Family stories have long been recognized as a vehicle for assessing components of a family's emotional and social life, including the degree to which an immigrant family has been willing to assimilate. Transnationalism, defined as living in one or more cultures and maintaining connections to both, is now increasingly common. A qualitative study of family stories in the family of those who appear completely "American" suggests that an affiliation with one's home country is nevertheless detectable in the stories via motifs such as (1) positively connotated home remedies, (2) continuing denigration of home country "enemies," (3) extensive knowledge of the home country history and politics, (4) praise of endogamy and negative assessment of exogamy, (5) superiority of home country to America, and (6) beauty of home country. Furthermore, an awareness of which model--assimilationist or transnational--governs a family's experience may help clarify a clinician's understanding of a family's strengths, vulnerabilities, and mode of framing their cultural experiences.  相似文献

In the present study, the authors investigated the effects of framing of options on risky decision making in groups of younger adults (M = 23.8 years, n = 192) and older adults (M = 69.1 years, n = 192). The participants were assigned to one of three scenarios varying in the goods at stake (human lives, paintings, money). The authors observed a majority preference in favor of the risky options after negative, but not positive framing. They also found, as they had predicted, that the type of framing effect varied across scenarios, with a bidirectional framing effect for the life-death scenario and unidirectional (risk averse) framing effects when public property (paintings) or personal property (money) were at stake. It is important to note that these choice preference patterns were highly similar across the age groups, which reinforced the conclusion that younger and older adults are equally susceptible to framing effects.  相似文献
