Drawing as Process: Expansiveness Through Constraint
This paper explores the concept of drawing as a time-based practice, where the process is the core of the artwork rather than the finished product. I divide my artistic concerns into four chapters, each advancing on the previous one, to discuss my drawing practice, which allows for exploration of time and space across a wide array of media and styles of representation. I embrace impulse and intuition in the mark-making process, letting go of control while prioritizing the form of depicted figures over their image. This paper highlights the importance of my inner contradiction and how the process reflects my thought patterns, rather than simply the result. Additionally, I find affinity in the works of referenced artists and writers, including Amy Sillman, Brian Rutenberg, Steffani Jemison, and Sarah Sze, as their theories that examine the process of making are relevant to my practice. Eventually, my improvised experiments of drawing in my thesis artwork, Geese, Why Geese?, exemplify the features of my works that explore the boundaries between progress and product, discipline and madness, and opens new possibilities to find expansiveness through constraint
A poor man's positive energy theorem: II. Null geodesics
We show that positivity of energy for stationary, or strongly uniformly
Schwarzschildian, asymptotically flat, non-singular domains of outer
communications can be proved using Galloway's null rigidity theorem.Comment: Latex2e, 24 A4 pages, minor change
Cauchy horizons in Gowdy space times
We analyse exhaustively the structure of \emph{non-degenerate} Cauchy
horizons in Gowdy space-times, and we establish existence of a large class of
non-polarized Gowdy space-times with such horizons.
Added in proof: Our results here, together with deep new results of H.
Ringstr\"om (talk at the Miami Waves conference, January 2004), establish
strong cosmic censorship in (toroidal) Gowdy space-times.Comment: 25 pages Latex. Further information at http://grtensor.org/gowdy
Classifiers With a Reject Option for Early Time-Series Classification
Early classification of time-series data in a dynamic environment is a
challenging problem of great importance in signal processing. This paper
proposes a classifier architecture with a reject option capable of online
decision making without the need to wait for the entire time series signal to
be present. The main idea is to classify an odor/gas signal with an acceptable
accuracy as early as possible. Instead of using posterior probability of a
classifier, the proposed method uses the "agreement" of an ensemble to decide
whether to accept or reject the candidate label. The introduced algorithm is
applied to the bio-chemistry problem of odor classification to build a novel
Electronic-Nose called Forefront-Nose. Experimental results on wind tunnel
test-bed facility confirms the robustness of the forefront-nose compared to the
standard classifiers from both earliness and recognition perspectives
Does asymptotic simplicity allow for radiation near spatial infinity?
A representation of spatial infinity based in the properties of conformal
geodesics is used to obtain asymptotic expansions of the gravitational field
near the region where null infinity touches spatial infinity. These expansions
show that generic time symmetric initial data with an analytic conformal metric
at spatial infinity will give rise to developments with a certain type of
logarithmic singularities at the points where null infinity and spatial
infinity meet. These logarithmic singularities produce a non-smooth null
infinity. The sources of the logarithmic singularities are traced back down to
the initial data. It is shown that is the parts of the initial data responsible
for the non-regular behaviour of the solutions are not present, then the
initial data is static to a certain order. On the basis of these results it is
conjectured that the only time symmetric data sets with developments having a
smooth null infinity are those which are static in a neighbourhood of infinity.
This conjecture generalises a previous conjecture regarding time symmetric,
conformally flat data. The relation of these conjectures to Penrose's proposal
for the description of the asymptotic gravitational field of isolated bodies is
discussed.Comment: 22 pages, 4 figures. Typos and grammatical mistakes corrected.

Paths to the Baccalaureate at a Hispanic-Serving Institution: The Lived Experiences of Latinos who Entered Higher Education at the Community College
The U.S. Census indicates that Hispanic participation in postsecondary education tripled between 1996 and 2016. If the traditional outcome measure of the six-year graduation rate is used, however, increased participation has not resulted in an increased number of Latinos who complete a bachelor’s degree. Further, typical examinations of baccalaureate completion have focused on the starting point—beginning at a community college or beginning at a four-year college or university and compare percentages of completion by race or ethnicity. Findings of such studies point to the disparity in bachelor’s degree completion rates between Latinos and other racial and ethnic groups and that the disparity is even greater among individuals who begin postsecondary education at the community college. This paper follows an anti-deficit approach to gain a greater understanding of the complexities of baccalaureate completion of Latina/o students beyond the common measure of a six-year timeframe and the simplified starting point of the community college. Learning from the success of the participants may provide insight helpful to educational leaders who seek to provide access and facilitate the success of Latino students

EVOLUTION OF STIGMA: UNDERSTANDING THE PROGRESSION OF STIGMA ON RECEIVING MENTAL HEALTH SERVICES WITHIN LATINX COMMUNITIES IN THE INLAND EMPIRE
The stigmatization of mental health services within the Latinx community has led to the underutilization of these services within this population. This study examined whether the stigma on receiving mental health services has evolved over the years within the Latinx community of the Inland Empire region. An analysis of the evolution of this stigma brings insight on why this stigma exists, and what has made it increase or decrease. The study was conducted through a qualitative procedure; Individual interviews were conducted where the information gathered was analyzed through thematic analysis to identify overlapping ideas and topics. The findings supported that the perspectives on mental health services within the Latinx community differ according to generations, and that the stigma has decreased over the years. To improve mental health within the Latinx community, there needs to be efforts to destigmatize receiving mental health services. Additionally, To improve and sustain the goals of the public sector and to provide the adequate services, the mental health needs of the Latinx community need to be met. A better understanding of the stigmatization of mental health services will improve the services provided by social workers and all other mental health services providers
On "many black hole" space-times
We analyze the horizon structure of families of space times obtained by
evolving initial data sets containing apparent horizons with several connected
components. We show that under certain smallness conditions the outermost
apparent horizons will also have several connected components. We further show
that, again under a smallness condition, the maximal globally hyperbolic
development of the many black hole initial data constructed by Chrusciel and
Delay, or of hyperboloidal data of Isenberg, Mazzeo and Pollack, will have an
event horizon, the intersection of which with the initial data hypersurface is
not connected. This justifies the "many black hole" character of those
space-times.Comment: several graphic file
