This article concerns the relations between personality and quality of life. In the first part, we discuss different conceptualizations of personality and quality of life. We argue that personality affects quality of life by influencing how people approach and react to critical life situations. In the second part, we address the beneficial role played by two individual difference variables in promoting quality of life: dispositional optimism and goal adjustment. Literature is reviewed demonstrating that dispositional optimism facilitates subjective well-being and good health, mediated by a person's coping behaviors. In addition, we discuss studies that examine people who confront unattainable goals. The reported evidence supports the conclusion that individual differences in people's abilities to adjust to unattainable goals are associated with a good quality of life.  相似文献

OBJECTIVE: To examine the extent to which the public's desire for social distance from people with schizophrenia is influenced by beliefs about the disorder and stereotypes about those suffering from it. METHODS: In spring 2001, we carried out a representative survey of individuals of German nationality aged 18 years and over (n = 5025). Each subject was given a fully structured interview that began with the presentation of a vignette. RESULTS: Both labelling and beliefs about the disorder's causes and prognosis, as well as the perception that those suffering from it are unpredictable and dangerous, had an impact on the public's desire for social distance. However, the latter proved to be more important. As expected, respondents who identified the disorder depicted in the vignette as mental illness, those who blamed the individual for its development, and those who anticipated a poor prognosis expressed a stronger desire for social distance. Endorsing biological factors as a cause was also associated with increased social distance. CONCLUSIONS: Our findings have important implications for interventions aimed at reducing stigma and discrimination related to schizophrenia. Targeting the stereotype of unpredictability and dangerousness appears to be particularly important.  相似文献

In nursing literature, Heideggerian hermeneutics, as expounded in Being and Time , is taken well near unanimously to be an invitation to explore tradition and culture. Understanding, we are told in the name of Heidegger, is to be found in the realm of common meanings and shared practices. This interpretation of what Heidegger is about in Being and Time is neither unchallengeable nor unchallenged. While a number of scholars can be found to agree with it, there are many others who see it as an utter misreading of Heidegger. In their judgement, it is an interpretation diametrically opposed to what Heidegger sets forth in his treatise. For researchers interested in invoking Heidegger or following a Heideggerian approach, this is a frustrating impasse. The only valid starting point for resolving it, this article suggests, is a close reading of what Heidegger actually says in the pages of Being and Time .  相似文献

Solitary necrotic nodule of the liver is an unusual lesion that is often an incidental finding on abdominal imaging, intraoperative examination, or post mortem. Most reported cases of solitary necrotic nodule have been in males, and over three quarters of these lesions have occurred in the right lobe of the liver. Pathologically, solitary necrotic nodule is a benign lesion characterized by a completely necrotic core that is often partly calcified, surrounded by a dense hyalinized fibrous capsule containing elastin fibres. The ultrasound appearance of solitary necrotic nodule is usually of a “target” lesion with a hyperechoic center, while on CT scan they appear as non-enhancing hypodense lesions that are typical of metastatic adenocarcinoma or peripheral cholangiocarcinoma. The impression of malignancy is further enforced with the finding of necrotic cellular material on biopsy and the macroscopically hard and “gritty” nature of the nodules. Currently, permanent histopathology of solitary necrotic nodules is the only accurate method of diagnosis. However, solitary necrotic nodules are usually of a bilobed or lobulated shape that is unusual for malignant liver lesions, and they often lie in close proximity to hepatic inflow structures. Solitary necrotic nodule should be suspected in liver lesions with this configuration, location, and on a biopsy showing a large amount of necrosis.  相似文献

Background: Intervention trials with self-selected participants have shown that mailed stage-targeted print materials can increase participation in physical activity in the short term. We examined the effects of a mailed stage-targeted print intervention designed to promote physical activity, in a random sample of adults living in a regional city.Method: Participants (n = 462, 40–60 years of age) were randomly allocated to an intervention in - 227) or control group (n - 235). Measures included validated 2-week physical activity recall and stage of motivational readiness for physical activity. The intervention consisted of a single mailing of a letter and full-color stage-targeted booklets (specific to precontemplation, contemplation, preparation, and action/maintenance) 1 week postbaseline. Follow-up interviews were conducted at 2 and 6 months postbaseline.Results: After 2 months, participants in the intervention group were significantly More likely to meet the current American College of Sports Medicine/Centers for Disease Control and Prevention recommendation for sufficient physical activity than those in the control group (adjusted odds ratio [OR] - 2.40; 95% confidence interval [CI] = 1.44–3.99). After 6 months, intervention participants who reported receiving and reading the intervention materials were significantly more likely to be meeting the sufficient physical activity criterion compared with the control group (adjusted OR = 2.03; 95% Cl = 1.16–3.56).Conclusions: The stage-targeted print intervention was effective in promoting short-term increases in physical activity and was most effective for participants who recognized and used the materials. This low-cost, generalizable intervention has demonstrated potential as a practical population-based physical activity promotion strategy. Further research is required before widespread dissemination would be justified, as additional strategies may be required to ensure sustained change.

Summary The BTA Test is an adjunctive test for the diagnosis and management of bladder cancer. For estimation of its potential in the management of patients with transitional-cell cancer (TCC) a review of published results was undertaken. Three prospective studies were analyzed, in which a total of 699 patients with a history of TCC were enrolled. The BTA Test was performed on voided urine and compared with either voided-urine or bladder-wash cytologic analysis in a blinded fashion. In all three studies the sensitivity of the BTA Test was more than double that of cytology, irrespective of whether the cytologic analysis was performed on voided or bladder-wash samples. The third study also included an additional 225 patients undergoing evaluation for hematuria, and TCC was found in 67 cases. The BTA Test detected 70% of these tumors, whereas cytology detected only 25%. The BTA Test is a simple, rapid test that can diagnose a substantial percentage of patients having new or recurrent bladder TCC. Its complete role in the management of such patients remains to be defined.  相似文献

A new dual-energy x-ray CT algorithm is presented which makes use of both pre- and post-reconstruction data in an iterative manner to achieve accurate beam hardening correction and decomposition into basis materials. The technique does not require a calibration phantom and also does not require accurate estimation of the effective energies of the polyenergetic x-ray beams. It does however, require a knowledge of the incident x-ray spectra. For the situation where the incident spectra are unknown, a method is given whereby sufficiently accurate approximations to the spectra can be determined from attenuation measurements. Decomposition into basis materials makes use of spatial and energy information and an 'a priori' knowledge of the composition and attenuating properties of various tissue types. Any total number of basis materials may be used within the limitation that a subset containing a maximum of three materials is used for any individual pixel. Results of a computer simulation show that the algorithm produces accurate measurements of the concentrations of both high and low atomic number materials such as bone mineral, collagen, fat and air. However the results of a phantom study show that the measurement of the concentrations of low atomic number basis materials may be subject to systematic errors arising from uncertainties in the published values of linear attenuation coefficients.  相似文献
