Muscular ideal media images and men's body image: Social comparison processing and individual vulnerability.

Abstract: The study aimed to investigate the role of social comparison processes in men's responses to images of muscular-ideal male beauty. A sample of 104 male university students viewed either 15 television commercials containing images of men who epitomize the current muscular ideal, or 15 nonappearance c

Electrons and photons colliding with atoms: development and application of the convergent close-coupling method

Abstract: The substantial progress that has occurred during the 1990s in the field of electron-atom-collision theory is discussed. We show how a solution of a small-model three-body problem, using the convergent close-coupling method, has led to numerous applications involving real atomic collision systems. Consequently many fundamental electron-atom collision processes are considered as 'solved', and accurate collision data of interest to science and industry have become available. However, we suggest that the present has only just seen the birth of modern atomic collision theory. There are many more important collision problems to be tackled, with guidance coming from experiment being as important as ever.

Cramer-Rao lower bounds for QAM phase and frequency estimation

Abstract: In this paper, we present the true Cramer-Rao lower bounds (CRLBs) for the estimation of phase offset for common quadrature amplitude modulation (QAM), PSK, and PAM signals in AWGN channels. It is shown that the same analysis also applies to the QAM, FSK, and PAM CRLBs for frequency offset estimation. The ratio of the modulated to the unmodulated CRLBs is derived for all QAM, PSK, and PAM signals and calculated for specific cases of interest. This is useful to determine the limiting performance of synchronization circuits for coherent receivers without the need to simulate particular algorithms. The hounds are compared to the existing true CRLBs for an unmodulated carrier wave (CW), BPSK, and QPSK. We investigated new and existing QAM phase estimation algorithms in order to verify the new phase CRLB. This showed that new minimum distance estimator performs close to the QAM bound and provides a large improvement over the power law estimator at moderate to high signal-to-noise ratios.

Validity of the malnutrition screening tool as an effective predictor of nutritional risk in oncology outpatients receiving chemotherapy

Abstract: To determine the relative validity of the Malnutrition Screening Tool (MST) compared with a full nutrition assessment by the scored Patient Generated-Subjective Global Assessment (PG-SGA) and to assess MST inter-rater reliability in patients receiving chemotherapy. An observational, cross-sectional study was conducted at an Australian public hospital in 50 oncology outpatients receiving chemotherapy. Inter-rater reliability was assessed in a subsample of 20 patients. According to PG-SGA global rating, the prevalence of malnutrition was 26%. The MST was a strong predictor of nutritional risk relative to the PG-SGA (100% sensitivity, 92% specificity, 0.8 positive predictive value, 1.0 negative predictive value). MST inter-rater reliability was acceptable with agreement by administration staff/nursing staff/patient and the dietitian in 18/20 cases (kappa=0.83; p0.001). The MST has acceptable relative validity, inter-rater reliability, sensitivity, and specificity to identify chemotherapy outpatients at risk of malnutrition and, hence, is an acceptable nutrition screening tool in this patient population.
