Are You An Emissary of Jesus Christ?: Justice, The Catholic Church and the Chicano Movement
In 1969, Católicos Por La Raza (CPLR) emerged as an ethnic protest group against the injustices of the American Catholic Church in San Diego and Los Angeles, California. CPLR was critical of the Catholic hierarchy\u27s inconsistencies in relation to the Chicano community. As one of the wealthiest institutions, the Catholic Church was doing very little for a community that made up the largest part of the Church\u27s membership. For CPLR, the Christian message of justice was not practiced by the leaders of the Church. In Los Angeles, Chicanos were asking why the Archdiocese chose to close a high school in the barrio, due to lack of funds, but could still afford to build a three million dollar cathedral in downtown Los Angeles. In San Diego, Chicanos were asking the Catholic Church to become intimately involved in the everyday struggles of the Chicano community. Within this dialogue emerged a clear concept of justice and its meaning for CPLR members in relationship to the hierarchy of the American Catholic Church
Introduction
From the margins, we find ourselves well positioned to tell other stories -- life histories, traditions, and cultural myths which typically go unheard in dominant society.[2] As illustrated in the lead article, A Pattern of Possibility: Maxine Hong Kingston\u27s Woman Warrior, by Thelma J. Shinn, such stories are meronymic -- mero from the Greek meaning part -- because our unique social location allows us to see beyond the dominant mythos and tell other parts of the story. Telling these stories is not only empowering to those whom we name, but it also changes and transforms the official storyline itself. Life stories of marginalized peoples demonstrate time and again that there is no one story, no one way of seeing, thinking, or feeling. Moreover, the core of these stories and identities reveal multiple parts of a more inclusive story, a more inclusive way of thinking. Further, meronymic stories unveil the complex operations of power and domination which have denied and suppressed other voices. This special issue of Explorations in Ethnic Studies on race, class, and gender is devoted to telling the other parts of the story
Detection of the relaxation rates of an interacting quantum dot by a capacitively coupled sensor dot
We present a theoretical study of the detection of the decay time scales for
a single-level quantum dot by means of a capacitively coupled sensor dot, which
acts as an electrometer. We investigate the measurement back-action on the
quantum-dot decay rates and elucidate its mechanism. We explicitly show that
the setup can be used to measure the bare quantum-dot relaxation rates by
choosing gate pulses that minimize the back-action. Interestingly, we find that
besides the charge relaxation rate, also the rate associated to the fermion
parity in the dot can be accessed with this setup.Comment: 15 pages, 6 figure
Non-equilibrium correlations and entanglement in a semiconductor hybrid circuit-QED system
We present a theoretical study of a hybrid circuit-QED system composed of two
semiconducting charge-qubits confined in a microwave resonator. The qubits are
defined in terms of the charge states of two spatially separated double quantum
dots (DQDs) which are coupled to the same photon mode in the microwave
resonator. We analyze a transport setup where each DQD is attached to
electronic reservoirs and biased out-of-equilibrium by a large voltage, and
study how electron transport across each DQD is modified by the coupling to the
common resonator. In particular, we show that the inelastic current through
each DQD reflects an indirect qubit-qubit interaction mediated by off-resonant
photons in the microwave resonator. As a result of this interaction, both
charge qubits stay entangled in the steady (dissipative) state. Finite shot
noise cross-correlations between currents across distant DQDs are another
manifestation of this nontrivial steady-state entanglement.Comment: Final versio
About the limits of microfiltration for the purification of wastewaters
In the past, microfiltration was widely used as a
pretreatment step for wastewater stream purification
purposes. Experiences performed during the last years
shows that microfiltration fails to maintain its
performances for longer period of times. Many case studies
demonstrate that the adoption of microfiltration leads to
the failure of the overall process; the severe fouling of the
microfiltration membranes leads to high operating costs
with the consequence to make the treatment of the
wastewater economically unfeasible. The boundary flux
concept is a profitable tool to analyze fouling issues in
membrane processes. The boundary flux value separates an
operating region characterized by reversible fouling
formation from irreversible one. Boundary flux values are
not content, but function of time, as calculated by the subboundary
fouling rate value. The knowledge of both
parameters may fully describe the membrane performances
in sub-boundary operating regimes. Many times, for
wastewater purification purposes, ultrafiltration
membranes appear to be suits better to the needs, even they
exhibit lower permeate fluxes compared to microfiltration.
Key to this choice is that ultrafiltration appears to resist
better to fouling issues, with a limited reduction of the
performances as a function of time. In other words, it
appears that ultrafiltration exhibit higher boundary flux
values and lower sub-boundary fouling rates. In this work,
after a brief introduction to the boundary flux concept, for
many different wastewater streams (more than 20,
produced by the most relevant industries in food,
agriculture, manufacture, pharmaceutics), the boundary
flux and sub-boundary fouling rate values of different
microfiltration and ultrafiltration membranes will be
discussed and compared. The possibility to successfully
use microfiltration as a pretreatment step strongly depends
on the feedstock characteristics and, in detail, on the
particle size of the suspended matter. In most cases,
microfiltration demonstrates to be technically unsuitable
for pretreatment purposes of many wastewater streams; as
a consequence, the adoption of microfiltration pushes
operators to exceed boundary flux conditions, therefore
triggering severe fouling, that leads to economic
unfeasibility of the process in long terms
Immunity of Volunteer Health Care Providers in Texas: Bartering Legal Rights for Free Medical Care (Comment)
This comment will explore the ramifications of recent Texas legislation affecting the indigent beneficiaries of free health care services and why we elect this particular option of caring for the poor. This comment will delve into the idea of health care as a fundamental human right and how this idea relates to the American definition of poverty. The problem of inadequate access to health care among the poor will be examined, with a discussion of the recent creation of volunteer immunity in Texas and similar legislation in other states. This comment will also evaluate the reliance of the poor on charity. Finally, alternative solutions will be proposed to the problem of indigent access to health care
Sound Healing
Most people would imply that music is used for solely entertainment, artistic expression, celebration, ceremony, or communication. Whether we are musically inclined or not, music is the one thing that genuinely connects humans from all cultures and corners of the earth. Another application of music is sound healing, a therapeutic practice that utilizes different signals and vibrations to improve the physical and emotional health of individuals, groups, and cultures. This can entail listening to various musical experiences (such as a concert), singing along to a favorite song or chant, dancing to the beats of other music, meditating, or playing an instrument. Specific instruction from a specialized practitioner might incorporate a one-on-one or an in-group type of session. Usually, sessions involve sitting or lying down while listening to formulated music or sounds played through a monitor either from special instruments that have been around for centuries or incorporating frequency and sound vibrations applied using special instrumental tools, such as a tuning fork. This research paper will describe what sound is, how sound can travel from a physiological standpoint, and the components used to identify a sound. In addition, the author will touch on the origins of sound healing from ancient times, different types of sound therapies based upon performance, specific instruments and tools, and the science, psychological theories, and methods of these applied practices. This research aims to examine, educate, and discuss sources of overall well-being for potential healing through sound as medicine for the past, present, and future. However, scientists, physicians, professors, and licensed therapists have yet to partake in adequate healthcare-related research on this topic, leaving further room for evidence to support these claims
Time scales in the dynamics of an interacting quantum dot
We analyze the dynamics of a single-level quantum dot with Coulomb
interaction, weakly tunnel coupled to an electronic reservoir, after it has
been brought out of equilibrium, e.g. by a step-pulse potential. We investigate
the exponential decay towards the equilibrium state, which is governed by three
time scales. In addition to the charge and spin relaxation time there is a
third time scale which is independent of the level position and the Coulomb
interaction. This time scale emerges in the time evolution of physical
quantities sensitive to two-particle processes.Comment: Version accpeted in PR
