Given the implications of stigma for HIV/AIDS prevention and control of the epidemic, as emphasized by UNAIDS, this study analyzes the Brazilian academic production on health, AIDS, stigma, and discrimination, available in the SciELO database from 2005 to 2010. Brazilian research on the theme is modest as compared to the international literature, but the studies follow the same trend of focusin...

Scholarly and anecdotal evidence suggests that despite an increasing tolerance for diversity among many Americans, workplace discrimination is on the rise. This article addresses the role that learning, or more specifically barriers to learning, plays in the perpetuation of discrimination. We use several organizationally based learning theories to illustrate ways in which firms may fail to lear...

Price discrimination refers to the practice of dynamically varying the prices of goods based on a customer’s purchasing power and willingness to pay. In this paper, motivated by several anecdotal accounts, we report on a three-week experiment, conducted in search of price discrimination in airline tickets. Despite presenting the companies with multiple opportunities for discriminating us, and c...

A psychophysical method is proposed to separate the contrast dependence of internal response and its noise. The resulting contrast relationships represent a signature of the visual processing stage that limits the human observer's performance. The method was applied to contrast discrimination for sustained and transient Gabor patches with a 3 cycle/deg spatial carrier. For both stimulus types t...

The present study explores if EEG spectral parameters can discriminate between healthy elderly controls (HC), Alzheimer's disease (AD) and vascular dementia (VaD) using. We considered EEG data recorded during normal clinical routine with 114 healthy controls (HC), 114 AD, and 114 VaD patients. The spectral features extracted from the EEG were the absolute delta power, decay from lower to higher...

Earlier research has shown that power relationships at workplaces are constructed by power structures. Processes related to power always influence the working conditions for (in this study in elderly care) the working groups involved. Power structures are central for intersectional analysis, in the sense that the intersectional perspective highlights aspects such as gender and ethnicity (subjec...

Article IV imposes prohibitions on interstate discrimination that are central to our status as a single nation, yet the Constitution also grants Congress broad power over interstate relations. This raises questions with respect to the scope of Congress's power over interstate relations, what is sometimes referred to as the horizontal dimension of federalism. In particular, does Congress have th...

In this paper a new method is proposed that can be used to differentiate faults from switching transients. The method is primarily intended for use in systems where fast fault detection and fast fault clearing before the first peak of the fault current are required. An industrial system, in which high short-circuit power is desired but in which high shortcircuit currents cannot be tolerated is ...

A computer simulation of nonlinear correlators with (-k)th-law nonlinearity has been implemented. The nonlinearity is applied to the input-image power spectrum, with either a matched filter or a phase-only filter representing the reference object. Optimal correlators (with an exactly known power spectrum of the background-image component) and suboptimal correlators have been studied in order to...
