Fifty Shades of Leather and Misogyny: An Investigation of Anti-Woman Perspectives among Leathermen
The Fifty Shades books and films shed light on a sexual and leather-clad subculture predominantly kept in the dark: bondage, discipline, submission, and sadomasochism (BDSM). Such new interest in this community also generated widespread misconceptions about the sexual practices that take place in these circles, especially in regard to the treatment of women. In the current study, we investigate how a BDSM or “leather” identity is related to attitudes toward women. We use a nationally representative sample of U.S. adult men aged 18–64 stratified by U.S. Census categories of age, race/ethnicity, and census region (N = 1474) and a subsample of leathermen (n = 65; 58% hetero-leather identified and 42% nonhetero- leather identified). Specifically, we explore leather identity as it relates to the support of laws/policies helping women, non-feminist identity, patriarchal gender norms, and the stigmatization of lesbian, bisexual, transgender, and queer (LBTQ) women among both hetero and non-hetero leathermen. Overall, our findings indicate a robust relationship between these anti-woman perspectives and leatherman identity that is especially pronounced among hetero leathermen and demonstrate the importance of continuing to consider how leather identity shapes misogyny among leathermen
Entanglement generation in harmonic chains: tagging by squeezing
We address the problem of spring-like coupling between bosons in an open
chain configuration where the counter-rotating terms are explicitly included.
We show that fruitful insight can be gained by decomposing the time-evolution
operator of this problem into a pattern of linear-optics elements. This allows
us to provide a clear picture of the effects of the counter-rotating terms in
the important problem of long-haul entanglement distribution. The analytic
control over the variance matrix of the state of the bosonic register allows us
to track the dynamics of the entanglement. This helps in designing a global
addressing scheme, complemented by a proper initialization of the register,
which quantitatively improves the entanglement between the extremal oscillators
in the chain, thus providing a strategy for feasible long distance entanglement
distribution.Comment: 8 pages, 8 figures, RevTeX
Detecting nonlocal Cooper pair entanglement by optical Bell inequality violation
Based on the Bardeen Cooper Schrieffer (BCS) theory of superconductivity, the
coherent splitting of Cooper pairs from a superconductor to two spatially
separated quantum dots has been predicted to generate nonlocal pairs of
entangled electrons. In order to test this hypothesis, we propose a scheme to
transfer the spin state of a split Cooper pair onto the polarization state of a
pair of optical photons. We show that the produced photon pairs can be used to
violate a Bell inequality, unambiguously demonstrating the entanglement of the
split Cooper pairs.Comment: 11 pages, 9 figures, v3 with added reference
Static and dynamical quantum correlations in phases of an alternating field XY model
We investigate the static and dynamical patterns of entanglement in an
anisotropic XY model with an alternating transverse magnetic field, which is
equivalent to a two-component one-dimensional Fermi gas on a lattice, a system
realizable with current technology. Apart from the antiferromagnetic and
paramagnetic phases, the model possesses a dimer phase which is not present in
the transverse XY model. At zero temperature, we find that the first derivative
of bipartite entanglement can detect all the three phases. We analytically show
that the model has a "factorization line" on the plane of system parameters, in
which the zero temperature state is separable. Along with investigating the
effect of temperature on entanglement in a phase plane, we also report a
non-monotonic behavior of entanglement with respect to temperature in the
anti-ferromagnetic and paramagnetic phases, which is surprisingly absent in the
dimer phase. Since the time dynamics of entanglement in a realizable physical
system plays an important role in quantum information processing tasks, the
evolutions of entanglement at small as well as large time are examined.
Consideration of large time behavior of entanglement helps us to prove that in
this model, entanglement is always ergodic. We observe that other quantum
correlation measures can qualitatively show similar features in zero and finite
temperatures. However, unlike nearest-neighbor entanglement, the
nearest-neighbor information theoretic measures can be both ergodic as well as
non-ergodic, depending on the system parameters.Comment: 20 Pages, 13 Figures, 2 Tables, Published versio
Culture in Mind - An Enactivist Account: Not Cognitive Penetration But Cultural Permeation
Advancing a radically enactive account of cognition, we provide arguments in favour of the possibility that cultural factors permeate rather than penetrate cognition, such that cognition extensively and transactionally incorporates cultural factors rather than there being any question of cultural factors having to break into the restricted confines of cognition. The paper reviews the limitations of two classical cognitivist, modularist accounts of cognition and a revisionary, new order variant of cognitivism – a Predictive Processing account of Cognition, or PPC. It argues that the cognitivist interpretation of PPC is conservatively and problematically attached to the idea of inner models and stored knowledge. In abandoning that way of understanding PPC, it offers a radically enactive alternative account of how cultural factors matter to cognition – one that abandons all vestiges of the idea that cultural factors might contentfully communicate with basic forms of cognition. In place of that idea, the possibility that culture permeates cognition is promoted
