Identifying a space for young Black Muslim women in contemporary Britain
Young Black Muslim Women (BMW) have complex, intersectional identities and exist at the margins of various identity groupings. Given this, members of the community can face societal relegation across, not only race and gender lines, but across religious ones, too. This paper explores the lived experiences of intragroup discrimination, identity and belonging in 11 young Black Muslim Women in the United Kingdom. In-depth, semi-structured interviews were conducted with participants and thematically analysed through the lens of intersectionality. The use of an intersectional framework facilitated an understanding of the manner in which the sample was multiply marginalised. Two key themes emerged from the interviews: firstly, around experiences of intragroup and intersectional discrimination and, secondly, around the challenges of responding to and coping with the negative effects of such discrimination. Participants discussed the cross-cutting nature through which they faced discrimination: from within the Black community; from within the Muslim community; and as a result of their gender. The non-exclusivity of these three identities result in constant encounters of discrimination along different dimensions to their personal identity. They also developed diverse means of coping with this marginalisation including drawing from religious beliefs and mobile identifications, i.e. performing different aspects of their identities in different contexts. The present study contributes to existing knowledge in its focus on an under-researched group and emphasises the negative effects of intragroup discrimination. The paper importantly highlights the diversity within the Black community and considers the (in)visibility of Black Muslim Women within society
Effect of feed cycling on specific growth rate, condition factor and RNA/DNA ratio of Labeo rohita
A study was conducted to evaluate the effect of feed cycling on specific growth rate, condition factor and RNA/DNA ratio of Labeo rohita. Fingerling L. rohita were randomly collected from Qadria Fish Farm and Hatchery, Multan, Pakistan and divided into control, 5 days and 10 days feed cycling groups. Specific growth rate (% g day-1), body composition, condition factor, and RNA/DNA ratio of individual fish and of each group were calculated. There was a highly significant (
Effect of Feed Cycling on Specific Growth Rate, Condition Factor, Body Composition And Rna/Dna Ratio Of Cirrhinus mrigala.
A randomly selected 60 samples of Cirrhinus mrigala, fingerling sized, were collected from Qadria fish hatchery and farm, Matital road, Multan. Fish were divided into three groups namely, control, 5 and 10 days cyclic feeding group. Specific growth rate (% g day-1), condition factor (K), body composition andRNA/DNA ratio of individual specimen and of each group were calculated. It was found that there was highly significant effect of feed cycling on specific growth rate (P0.05) suggesting a compensatory growth which was independent of length of starvation. Feed cycling had marked effect (
The Spin of Holographic Electrons at Nonzero Density and Temperature
We study the Green's function of a gauge invariant fermionic operator in a
strongly coupled field theory at nonzero temperature and density using a dual
gravity description. The gravity model contains a charged black hole in four
dimensional anti-de Sitter space and probe charged fermions. In particular, we
consider the effects of the spin of these probe fermions on the properties of
the Green's function. There exists a spin-orbit coupling between the spin of an
electron and the electric field of a Reissner-Nordstrom black hole. On the
field theory side, this coupling leads to a Rashba like dispersion relation. We
also study the effects of spin on the damping term in the dispersion relation
by considering how the spin affects the placement of the fermionic quasinormal
modes in the complex frequency plane in a WKB limit. An appendix contains some
exact solutions of the Dirac equation in terms of Heun polynomials.Comment: 27 pages, 11 figures; v2: minor changes, published versio
Concept and Implementation of Pes Program in the Cidanau Watershed: a Lesson Learned for Future Environmental Policy
Objective of the paper is to depict the concept of PES (Payment for Environmental Services) and its implementation in the Cidanau Watershed. This paper is a success story of PES implementation starting from the early adoption of the concept. The study shows that PES has impressed by many institutions, which was then initiated by PT KTI (Krakatau Tirta Industri) as a pilot project of the concept implementation. The main practice of PES implementation activities was promoting conservation farming, including transfer of conservation technology and trees growing. The conservation farming showed good development, which was characterized by more trees planted, more conservation technology applied, and more optimistic expectation for income increase. Moreover, PES Program will not only attract the farmers who participated in the program, but also other farmers who were not included in it. With such promising performance, PES Program can potentially be adopted by farmers and provide solution to various problems encountered in the Cidanau Watershed
Universal scaling properties of extremal cohesive holographic phases
We show that strongly-coupled, translation-invariant holographic IR phases at
finite density can be classified according to the scaling behaviour of the
metric, the electric potential and the electric flux introducing four critical
exponents, independently of the details of the setup. Solutions fall into two
classes, depending on whether they break relativistic symmetry or not. The
critical exponents determine key properties of these phases, like thermodynamic
stability, the (ir)relevant deformations around them, the low-frequency scaling
of the optical conductivity and the nature of the spectrum for electric
perturbations. We also study the scaling behaviour of the electric flux through
bulk minimal surfaces using the Hartnoll-Radicevic order parameter, and
characterize the deviation from the Ryu-Takayanagi prescription in terms of the
critical exponents.Comment: v4: corrected a typo in eqn (3.29), now (3.28). Conclusions unchange
Holographic models for undoped Weyl semimetals
We continue our recently proposed holographic description of single-particle
correlation functions for four-dimensional chiral fermions with Lifshitz
scaling at zero chemical potential, paying particular attention to the
dynamical exponent z = 2. We present new results for the spectral densities and
dispersion relations at non-zero momenta and temperature. In contrast to the
relativistic case with z = 1, we find the existence of a quantum phase
transition from a non-Fermi liquid into a Fermi liquid in which two Fermi
surfaces spontaneously form, even at zero chemical potential. Our findings show
that the boundary system behaves like an undoped Weyl semimetal.Comment: 64 pages, 19 figure
N-player quantum games in an EPR setting
The -player quantum game is analyzed in the context of an
Einstein-Podolsky-Rosen (EPR) experiment. In this setting, a player's
strategies are not unitary transformations as in alternate quantum
game-theoretic frameworks, but a classical choice between two directions along
which spin or polarization measurements are made. The players' strategies thus
remain identical to their strategies in the mixed-strategy version of the
classical game. In the EPR setting the quantum game reduces itself to the
corresponding classical game when the shared quantum state reaches zero
entanglement. We find the relations for the probability distribution for
-qubit GHZ and W-type states, subject to general measurement directions,
from which the expressions for the mixed Nash equilibrium and the payoffs are
determined. Players' payoffs are then defined with linear functions so that
common two-player games can be easily extended to the -player case and
permit analytic expressions for the Nash equilibrium. As a specific example, we
solve the Prisoners' Dilemma game for general . We find a new
property for the game that for an even number of players the payoffs at the
Nash equilibrium are equal, whereas for an odd number of players the
cooperating players receive higher payoffs.Comment: 26 pages, 2 figure
Cooper pairing near charged black holes
We show that a quartic contact interaction between charged fermions can lead
to Cooper pairing and a superconducting instability in the background of a
charged asymptotically Anti-de Sitter black hole. For a massless fermion we
obtain the zero mode analytically and compute the dependence of the critical
temperature T_c on the charge of the fermion. The instability we find occurs at
charges above a critical value, where the fermion dispersion relation near the
Fermi surface is linear. The critical temperature goes to zero as the marginal
Fermi liquid is approached, together with the density of states at the Fermi
surface. Besides the charge, the critical temperature is controlled by a four
point function of a fermionic operator in the dual strongly coupled field
theory.Comment: 1+33 pages, 4 figure
Semi-local quantum liquids
Gauge/gravity duality applied to strongly interacting systems at finite
density predicts a universal intermediate energy phase to which we refer as a
semi-local quantum liquid. Such a phase is characterized by a finite spatial
correlation length, but an infinite correlation time and associated nontrivial
scaling behavior in the time direction, as well as a nonzero entropy density.
For a holographic system at a nonzero chemical potential, this unstable phase
sets in at an energy scale of order of the chemical potential, and orders at
lower energies into other phases; examples include superconductors and
antiferromagnetic-type states. In this paper we give examples in which it also
orders into Fermi liquids of "heavy" fermions. While the precise nature of the
lower energy state depends on the specific dynamics of the individual system,
we argue that the semi-local quantum liquid emerges universally at intermediate
energies through deconfinement (or equivalently fractionalization). We also
discuss the possible relevance of such a semi-local quantum liquid to heavy
electron systems and the strange metal phase of high temperature cuprate
superconductors.Comment: 31 pages, 7 figure
