1. Self-reported disability in women with fibromyalgia from a tertiary care center
Abstract Background: The World Health Organization Disability Assessment Schedule (WHODAS) 2.0 is a generic instrument to assess disability. Pain and psychological factors seem to play a pronounced disabling role in fibromyalgia (FM). There are few studies that investigate the factors associated with disability in patients with fibromyalgia from the patient

2. Transferência de funções ordinais através de classes de estímulos equivalentes em surdos / Transfer of ordinal functions through stimulus classes in hearing impaired individuals
The bilingual approach, adopted for educating deaf people in Brazil, regards the Brazilian Sign Language (Libras) as the first language and the written Portuguese Language as the instrumental language. The acquisition of the written language may be more difficult than the acquisition of the sign language due to the differences between their ordinal grammatic

4. A influência da técnica do preparo cavitário utilizando laser Er: YAG e dos tipos de materiais restauradores na prevenção de cárie secundária
The influence of the cavity preparation technique and the types of restorative materials containing fluorides in the prevention of the secondary caries lesions was evaluated in this in vitro study. In a logic sequence the subject was approach by four manuscripts. The first study made a bibliographic revision about the laser employment in the prevention of th

5. Análise bayesiana em modelos TRI de três parâmetros. / Bayesian analysis for three parameters IRT models
In this dissertation the bayesian analysis for three parameters IRT (Item Response Theory) models with binaries and ordinals responses, considering the probit model, was discussed. For both cases, binary and ordinal, techniques based on MCCM (Monte Carlo Markov Chain) were used to estimate the items parameters. For binary response model, was considered two d

6. Comparative scaling of different nociceptives and neuropathic pains, by means of various psychophysical methods. / Escalonamento comparativo de diferentes dores nociceptivas e neuropáticas, por meio de métodos psicofísicos variados
The general aim of this study was to scale the different types of pain comparatively, by means of various psychophysical methods and different samples. The specific aims were: to compare the scaling of the different types of pain between the different samples; to compare the derived scales of ordinal judgments with the derived scales of ratio judgments; to v

7. Involvement of Protons as a Substrate for the Sucrose Carrier during Phloem Loading in Vicia faba Leaves 1
The effect of pH on uptake of exogenous sucrose by broadbean (Vicia faba L.) leaf discs without the lower epidermis has been investigated at various sucrose concentrations. The concentration dependence of sucrose uptake showed a biphasic saturation response. At high sucrose concentrations (>20 millimolar), sucrose uptake showed no pH dependence. At low sugar

8. Extended cervicomediastinal thymectomy in the integrated management of myasthenia gravis.
OBJECTIVE: The authors evaluated the response to extended cervicomediastinal thymectomy as a component of the integrated management of patients with myasthenia gravis in a large series of patients from a single institution. The authors evaluated the response to therapy with respect to a graded, multivariate, ordinal scale chosen to reflect the full range of

9. Score Tests for Association between Traits and Haplotypes when Linkage Phase Is Ambiguous
A key step toward the discovery of a gene related to a trait is the finding of an association between the trait and one or more haplotypes. Haplotype analyses can also provide critical information regarding the function of a gene; however, when unrelated subjects are sampled, haplotypes are often ambiguous because of unknown linkage phase of the measured sit

10. Sample size and power estimation for studies with health related quality of life outcomes: a comparison of four methods using the SF-36
We describe and compare four different methods for estimating sample size and power, when the primary outcome of the study is a Health Related Quality of Life (HRQoL) measure. These methods are: 1. assuming a Normal distribution and comparing two means; 2. using a non-parametric method; 3. Whitehead's method based on the proportional odds model; 4. the boots

11. Zoonotic illness--determining risks and measuring effects: association between current animal exposure and a history of illness in a well characterised rural population in the UK.
STUDY OBJECTIVES--To recruit a representative sample of farmworkers, accurately quantify the range and extent of their animal exposures, and measure the associated risks of illness. DESIGN--Inception cohort. SETTING--The study was undertaken among farmworkers living in five local authority areas in the catchment of Hereford and Preston Public Health Laborato
