For 30 days, 50 women with primary fibromyalgia syndrome reported daily progress and effort toward a health–fitness and a social–interpersonal goal and the extent to which their pain and fatigue hindered their accomplishment. They also carried palmtop computers to assess their sleep and their pain, fatigue, and positive and negative mood throughout the day. Analyses of the person–day data set showed than on days during which pain or fatigue increased from morning to evening, participants perceived their goal progress to be more attenuated by pain and fatigue. Unrestorative sleep the night before predicted the following day's effort and progress toward accomplishing health–fitness goals, but not social–interpersonal goals. Finally, participants who reported more progress toward social–interpersonal goals on a given day were more likely to evidence improvements in positive mood across the day, regardless of any changes in pain or fatigue that day.

PCR/SSOP typing methods were used to analyze the HLA Class II DRB1, DQA1, DQB1 and DPB1 loci of samples from three African American populations of Colombia. Forty samples from the Cauca (Pacific), and twenty samples each from the Choco (North Pacific Coast) and the Providencia (Caribbean island) populations, were collected and the Class II loci analyzed under the auspices of the Expedicion Humana. Despite the limited number of samples analyzed, the African Colombian populations exhibit a very high degree of class II polymorphism. A great diversity of DRB1 alleles was found, with representatives from all serological classes, including 19 DRB1 alleles in the Providencia, 16 in the Cauca and 14 in the Choco groups. In addition, a novel DQB1*02 allele (*0203) was found in two individuals from the Cauca population of the Pacific Coast. The sequence of the DQB1*0203 allele, associated with DR3, differs from DQB1*0201 by only one nucleotide substitution (C-->A) in the second position of codon 57, resulting in an Ala to Asp change. The addition of DQB1*0203 brings the total number of DQB1 alleles identified to date to 26. HLA class II diversity is much greater in these African Colombian populations than that seen in nearby Amerindian populations. Analysis of regional Colombian African American HLA population genetics is discussed with respect to the Colombian Amerindian HLA genetics described in an accompanying paper. 相似文献

对RFIC收发机设计来说,您需要大量的不同模拟技术和功能,如无线局域网(WLAN)或IEEE 802.11b中集成RFIC收发机发射部分应用的频域(谐波平衡)、混合频域和时域(电路包络)、电磁和混合数字域、频域和时域(无线测试台)。这些模拟技术速度快、效率高,对仍然使用传统时域模拟器的RFIC设计人员来说,他们仍应非常关注这些模拟技术。 相似文献

Discusses factors responsible for the previous neglect of substance abuse by health care professions and describes changes that have made it possible to include this field in clinical education and training. Various factors contributed to the neglect of substance abuse, including the social, psychological, and political distance between clinicians and those with intoxicant problems; the disruptive impact of early psychoanalytic thinking; and clinicians' lack of faith in the efficacy of treatment. As a more treatment-oriented group developed intoxicant problems, treatment facilities and techniques improved, leading to a greater optimism about outcome among clinicians. These and other changes make further education in this field feasible and desirable. A sample curriculum is presented for a full year's course of 26 2-hr seminars on this topic.

Applied probit analysis to 15 sets of data to specify the relationship between length of treatment and patient benefit. Data were based on more than 2,400 patients, covering a period of over 30 yrs of research. The probit model resulted in a good fit to these data, and the results were consistent across the studies, allowing for a meta-analytic pooling that provided estimates of the expected benefits of specific "doses" of psychotherapy. Analysis indicated that by 8 sessions approximately 50% of patients were measurably improved, and approximately 75% were improved by 26 sessions. Further analyses showed differential responsiveness for different diagnostic groups and for different outcome criteria. Findings hold promise for establishing empirical guidelines for peer review and 3rd-party financial support of psychotherapy.

This article proposes 2 new approaches to test a nonzero population correlation (ρ): the hypothesis-imposed univariate sampling bootstrap (HI) and the observed-imposed univariate sampling bootstrap (OI). The authors simulated correlated populations with various combinations of normal and skewed variates. With αset=.05, N≥10, and ρ≤0.4, empirical Type I error rates of the parametric r and the conventional bivariate sampling bootstrap reached .168 and .081, respectively, whereas the largest error rates of the HI and the OI were .079 and .062. On the basis of these results, the authors suggest that the OI is preferable in alpha control to parametric approaches if the researcher believes the population is nonnormal and wishes to test for nonzero ρs of moderate size.

In-plane shear behaviour of profiled steel sheeting 总被引:2,自引:0,他引:2
This paper will describe the behaviour of profiled steel sheeting under inplane shear and its application in building frames. Analytical models for shear strength and stiffness of the profiled steel sheeting are developed and validated by small scale model tests and finite element analyses. The strength, stiffness, failure modes and strain conditions are found to be greatly influenced by the boundary condition of the sheeting. The values of several factors related to the mode of attachment of the sheeting to practical building frames are studied to verify the suitability of design equations. 相似文献

Equivalency testing, a statistical method often used in biostatistics to determine the equivalence of 2 experimental drugs, is introduced to social scientists. Examples of equivalency testing are offered, and the usefulness of the method to the social scientist is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

The basal forebrain is important in cognitive processing. Most studies have focused on the importance of this area in mnemonic processing. However, the nucleus basalis magnocellularis (NBM), which is a major component of the basal forebrain, may also be involved in attentional processes. Attention can influence the sensitivity of perceptual processes, as assessed by discriminability, or the selection of response strategies, as assessed by bias. This experiment examined whether temporary inactivation of the NBM, using the gamma-aminobutyric acid (GABA) agonist muscimol, would interfere with attention. Each rat was tested in a 2-choice reaction time (RT) task in which stimulus frequency was varied. RT and error rate increased, and discriminability decreased following muscimol infusions into the NBM. Bias was unchanged. The pattern of results provides evidence that the NBM is important in attention, and this influence of the NBM acts primarily on perceptual aspects of attention.

Eight experiments were conducted to explore the relationships between goal level, valence, and instrumentality. Valence, measured in terms of anticipated satisfaction across a range of performance levels, was strongly but negatively related to goal level. This finding was explained by showing that low goals entail using less stringent standards for self-evaluation than do high goals. Instrumentality was positively associated with goal level. Ss believed that trying for hard goals would be more likely to give them a sense of achievement, develop their skills, and prove them competent than would trying for easy goals. Ss also believed that high goals would lead to more practical (job and life) benefits, as well as more pride and self-respect, than would low goals.
