Political attitudes as predictors of the multiple dimensions of mental health stigma.

Background: Mental health (MH) stigma is multidimensional and remains common in the United States and throughout the world. While sociopolitical attitudes such as right-wing authoritarianism (RWA) have emerged as strong predictors of some aspects of MH stigma, no study has assessed the relationship between RWA and multidimensional components of MH stigma, or linked this relationship to a theory of stigma.

Aims: The association between RWA and multiple stigma outcomes, including stereotypes, attributions/negative affect, social distance, microaggressions and help-seeking self-stigma was assessed controlling for covariates, including education, age, social desirability, race/ethnicity, gender, geographic location and prior contact with mental illness.

Sociodemographic Predictors of Sex Offender Stigma: How Politics Impact Attitudes, Social Distance, and Perceptions of Sex Offender Recidivism.

Stigma toward general criminal offenders has been found to be particularly salient among community members who identify as politically conservative; however, less is known about how political identification relates to stigma toward sex offenders. This is a particularly important area of inquiry, given that criminal jurisprudence and politics legitimatize stigmatizing labels attributed to sex offenders through laws and policies that apply specifically to this group. A nonrandom sample ( N = 518) of participants living in the United States was recruited for this survey study.

Experimental demonstration of quantum source coding.

We report an experimental demonstration of Schumacher's quantum noiseless coding theorem. Our experiment employs a sequence of single photons, each of which represents three qubits in terms of eight spatial and polarization modes. We initially prepare each photon in one of a set of eight nonorthogonal code word states corresponding to the value of a block of three binary letters.

Entanglement of indistinguishable particles shared between two parties.

Using an operational definition we quantify the entanglement, E(P), between two parties who share an arbitrary pure state of N indistinguishable particles. We show that E(P)< or =E(M), where E(M) is the bipartite entanglement calculated from the mode-occupation representation. Unlike E(M), E(P) is superadditive.
