Research Design

During the last five years the use of acupuncture in female infertility as an adjuvant to conventional treatment in assisted reproductive technology (ART) has increased in popularity.The present paper briefly discusses clinical and experimental data on the effect of acupuncture on uterine and ovarian blood flow, as an analgesic method during ART, and on endocrine and metabolic disturbances such as

The primary aim of the proposed study is to examine the efficacy of an 8-month supervised, high-intensity progressive resistance training and impact loading programme in comparison with a supervised machine-based isometric exercise training programme using the bioDensity system in older men with low bone mass. We will also determine the safety and acceptability of each exercise training mode. Intervention group responses will be compared with those of a self-selected, non-randomised control sample of sex-matched and age-matched men who will follow their usual lifestyle activities for 8 months. Apparently healthy men over 50 years with low bone mass, screened for medical conditions and medications known to adversely affect bone health, will be recruited. Eligible participants will be randomly allocated to 8 months of either exercise programme with block randomisation based on presence or absence of osteoporosis medications. A twice-weekly, 30-minute, supervised exercise programme wil...

We compared the effectiveness of two extinction interventions, extinction by omission and noncontingent delivery of reinforcement, to treat aggressive behavior with a 10-year-old boy. Before the intervention, a functional analysis revealed that aggression was maintained by positive reinforcement in the form of attention. The extinction by omission intervention consisted of ignoring aggressive behavior. Noncontingent reinforcement involved delivering attention to the boy on a fixed-time schedule. Both treatments were compared using a multielement research design. Noncontingent reinforcement produced a more rapid elimination of aggression. Additionally, the schedule of noncontingent reinforcement was gradually thinned during the intervention. Finally, both parents successfully implemented the noncontingent schedule of reinforcement independently for up to 5 weeks after treatment.

Unique in its integration of theory and application, this comprehensive book explains survey design, implementation, data analysis, and continuing data management, including how to effectively incorporate the latest technology (e.g., SurveyMonkey and Qualtrics). Data management and analysis are demonstrated and explained through statistical software including SPSS, SAS, and Stata. In addition to helping students develop a complete understanding of survey research from start to finish, the authors also address the challenges and issues of specific disciplines.

Bu kitap; duygusal ve davranışsal bozukluklara sahip öğrenciler hakkında bilgi sahibi olmak isteyen sınıf öğretmenleri, özel eğitim öğretmenleri ve alanda çalışan uzmanlar için hazırlanmış giriş niteliğinde bir uygulama kitabıdır. Her bir bozukluğun nedeni, tanımlanması, güncel araştırmalar ışığında verilmeye çalışılmış ve okul ortamındaki pratik uygulamalarla da anlatım zenginleştirilmiştir. Bunlara ek olarak belirli bir bozukluğun tüm yönlerine ilişkin temel yaklaşımla birlikte bilimsel olarak geliştirilmiş müdahele yöntemleri de verilmeye çalışılmıştır.

Bu kitabın alanda yeni çalışmaya başlayan öğretmenler kadar güncel verilerle desteklenen tanı koyma ve müdahele stratejilrine önem vermesi nedeniyle alanda uzun süredir çalışmakta olan öğretmenlere ve uzmanlara da yararlı olacağını düşünmekteyiz.

Comparative reviews of whole-body magnetic resonance imaging (WB-MRI) and positron emission tomography/computed tomography (CT; with different radiotracers) have shown that metastasis detection in advanced cancers is more accurate than with currently used CT and bone scans. However, the ability of WB-MRI and positron emission tomography/CT to assess therapeutic benefits has not been comprehensively evaluated. There is also considerable variability in the availability and quality of WB-MRI, which is an impediment to clinical development. Expert recommendations for standardising WB-MRI scans are needed, in order to assess its performance in advanced prostate cancer (APC) clinical trials. To design recommendations that promote standardisation and diminish variations in the acquisition, interpretation, and reporting of WB-MRI scans for use in APC. An international expert panel of oncologic imagers and oncologists with clinical and research interests in APC management assessed biomarker ...

Interest in the development of functions that estimate the likelihood of an individual suffering a future cardiovascular disease (CVD) event has increased in recent times (e.g. Framingham sheets, SCORE-Systematic COronary Risk Estimation, PROCAM, etc.). However, the estimates of absolute risk may show substantial variations between different populations, because of geographical, cultural, social, behavioural and genetic differences, as well as various methodological issues related to the predictive models employed. We sought to calibrate the SCORE equations to the Greek population. We used the SCORE system that offers an estimation of total fatal CVD risk in "high" and "low" CVD risk European countries. The project pulls together a pool of datasets from 12 European countries and 2.7 million person-years of observation. A mathematical procedure to adjust the risk estimates for individual countries was applied, based on local mortality and risk factor prevalence da...

A central commitment of current reforms in science education is that all students, regardless of culture, gender, race, and/ or socioeconomic status, are capable of understanding and doing science. The study “Bridging the Gap: Equity in Systemic Reform” assessed equity in systemic reform using a nested research design that drew on both qualitative and quantitative methodologies. As part of the study, case studies were conducted in two urban middle schools in large Ohio cities. The purpose of the case studies was to identify factors affecting equity in urban science education reform. Data were analyzed using Kahle's (1998) equity metric. That model allowed us to assess progress toward equity using a range of research-based indicators grouped into three categories critical for equitable education: access to, retention in, and achievement in quality science education. In addition, a fourth category was defined for systemic indicators of equity. Analyses indicated that the culture and climate of the case study schools differentially affected their progress toward equitable reform in science education. © 2001 John Wiley & Sons, Inc.

In this work, the vibrational spectral analysis was carried out using Raman and infrared spectroscopy in the range 100-4000 cm(-1) and 50-4000 cm(-1), respectively, for the title molecules. The molecular structure, fundamental vibrational frequencies and intensity of the vibrational bands are interpreted with the aid of structure optimizations and normal coordinate force field calculations based on Hartee Fock (HF) and density functional theory (DFT) method and different basis sets combination. The complete vibrational assignments of wave numbers were made on the basis of potential energy distribution (PED). The scaled B3LYP/6-311++G(d,p) results show the best agreement with the experimental values over the other methods. The effects due to the substitutions of methyl group and halogen bond were investigated. The results of the calculations were applied to simulated spectra of the title compounds, which show excellent agreement with observed spectra.
