How History Shaped Women\u27s Healthcare
At the beginnings of civilizations around the world, many of these inhabitants worshipped goddesses that connected them to the world and earth. However, invaders from male-dominated civilizations worked diligently to eliminate the faces and ideas of a woman in power. As time progressed, other events like the witch craze continued to minimize the influence of midwives and healers, creating a medical dynamic where only men “knew” the ways of a woman’s body. Thus, the birth of gynecology and American medicine put notions into place that did not allow women to pursue medical careers, further eradicating the possibility for a woman to understand her body and use it for her power. Industrialization during the turn of the twentieth century created a socioeconomic divide that left two different classes of women with different access to medical treatments. Overall, the constant exclusion and dehumanization of women throughout history affected the future of women’s healthcare in society

Minimal Models from W-Constrained Hierarchies via the Kontsevich-Miwa Transform
A direct relation between the conformal formalism for 2d-quantum gravity and
the W-constrained KP hierarchy is found, without the need to invoke
intermediate matrix model technology. The Kontsevich-Miwa transform of the KP
hierarchy is used to establish an identification between W constraints on the
KP tau function and decoupling equations corresponding to Virasoro null
vectors. The Kontsevich-Miwa transform maps the -constrained KP
hierarchy to the minimal model, with the tau function being
given by the correlator of a product of (dressed) (or )
operators, provided the Miwa parameter and the free parameter (an
abstract spin) present in the constraints are expressed through the ratio
and the level .Comment: 11 pp REVISED (minor changes in the presentation, easier to read
The Transition to College Process in PR-CETP Scholars
This article describes a study about the experiences of a group of students during the transition from high school to college. The students are future teachers who evidenced a high level of academic achievement in high school and received merit scholarships from the Puerto Rico Collaborative for Excellence in Teacher Preparation (PR-CETP). Two groups of students were compared: those who sustained a high GPA during their freshman year, and those who did not and, therefore, no longer qualified for the scholarship. The study was carried out through focused interviews with eight students, from three universities, four of whom maintained the scholarship and four who did not. Findings indicate that the main problems encountered were academic and social, and that the students received support from their families during the entire process. Regarding formal support, they pointed out that they felt highly satisfied with the services provided by PR-CETP and the universities, but they also pointed out (particularly those who lost the scholarship) that they needed additional services from the universities. They suggested, for example, better tutoring, and social activities among the scholars. The interviewed students, in general, consider that they faced the transition successfully since most of them described their academic, emotional, and social status as satisfactory at the time of the interviews
Chemical Oscillations out of Chemical Noise
The dynamics of one species chemical kinetics is studied. Chemical reactions
are modelled by means of continuous time Markov processes whose probability
distribution obeys a suitable master equation. A large deviation theory is
formally introduced, which allows developing a Hamiltonian dynamical system
able to describe the system dynamics. Using this technique we are able to show
that the intrinsic fluctuations, originated in the discrete character of the
reagents, may sustain oscillations and chaotic trajectories which are
impossible when these fluctuations are disregarded. An important point is that
oscillations and chaos appear in systems whose mean-field dynamics has too low
a dimensionality for showing such a behavior. In this sense these phenomena are
purely induced by noise, which does not limit itself to shifting a bifurcation
threshold. On the other hand, they are large deviations of a short transient
nature which typically only appear after long waiting times. We also discuss
the implications of our results in understanding extinction events in
population dynamics models expressed by means of stoichiometric relations
