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

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.

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
The Last Soviet Eastern
Alexander Proškin along with the screenwriter Edgar Dubrovský changed the Soviet eastern paradigm in 1987. All the previous ones had been set in the times of the Civil War or immediately afterwards. The Cold Summer of 1953, as it stands out from the title, does not. The eastern had always been set in the wildest period of the Soviet history and the intense heroism of that period in order to create an attractive dramatic situation (Biele slnko púšte /The White Sun of the Desert/, Nikto nechcel umierať /Nobody Wanted to Die/, Transsibírsky expres /Transsiberian Express/, Svoj medzi cudzími, cudzí medzi svojmi /Alone Amongst Strangers, Alone Amongst Fellows/, Svieť, svieť, hviezda moja /Shine, Shine, My Star/ etc. It was not possible to depict the 1950s as a negative „wild“ situation until the mid-1980s (actually, it was, soon after the 20th Party Congress, but it did not last long and it led to persecution of many including Solzhenitsyn)
Crypto and digital currencies- will governments allow these forms of new payments?
Since the 2010s cryptocurrencies have started to acquire a popularity never seen before, influencing the way the general population, investors, and governments treat investments. It is no surprise that central banks are pursuing their own digital currency in order to boost the security of transactions and reduce counterfeiting. Throughout this paper, we are going to analyze and compare the market valuation of the ten most valuable cryptocurrencies and explain if it is possible that one of them could become a viable and widely used currency in the future. Additionally, we are going to examine the central banks that will pursue their own digital currency and the reasons as of why they chose to venture into this new uncharted technology
On the area of the symmetry orbits in symmetric spacetimes with Vlasov matter
This paper treats the global existence question for a collection of general
relativistic collisionless particles, all having the same mass. The spacetimes
considered are globally hyperbolic, with Cauchy surface a 3-torus. Furthermore,
the spacetimes considered are isometrically invariant under a two-dimensional
group action, the orbits of which are spacelike 2-tori. It is known from
previous work that the area of the group orbits serves as a global time
coordinate. In the present work it is shown that the area takes on all positive
values in the maximal Cauchy development.Comment: 27 pages, version 2 minor changes and correction
