Latina Titans: A Journey of Inspiration

This qualitative research examined the journey of renowned female leadership in higher education. Two top level Latina administrators of universities were interviewed extensively to discover their journey to leadership. The theoretical framework used was Latina critical race theory, feminist theory, and counter-storytelling. Themes that surfaced were strong supportive mother, fervent faith, humble beginnings, mentors, intelligence, and challenges not obstacles. These guiding themes serve as a path for Latinas who aspire to higher educational leadership positions

Latina School Leadership: Breaking the Mold and Rising to the Top

For this qualitative research study, interviews with two Latina school leaders revealed their journeys to leadership. The theoretical framework used was Latina critical race theory, feminist theory, and counter storytelling. Identified themes were strong supportive mother, fervent faith, humble beginnings, mentors, intelligent, and challenges not obstacles. These guiding themes serve as a path for Latinas who aspire to public school leadership positions

Disparity In The Superintendency

This paper examines the career aspirations of female and male central office administrators and their reasons for or against pursuing a superintendency, in the Texas, K-12 public school arena. Information unique to seeking and attaining superintendencies by these central office administrators will be presented, to assist with illuminating gender specific commonalities and differences, between all of the superintendent aspirants, involved in the study. This study provides insight, as to why gender disparity persists in the office of the superintendency, despite the availability of similarly, talented female and male central office administrators who aspire to gain the position of superintendent

Small-Scale and Large-Scale Interventions to Improve [State] Student’s College Readiness

We are conducting two interventions aimed at improving entering students’ college readiness and mathematics placement. The small-scale intervention is aimed at working with students on the university campus. Students who are targeted have high school course work indicating that they have experience in Calculus or Pre-Calculus courses, but whose placement tests have not indicated they are ready for Calculus. At our institution this is a significant number of students and the goal of the project is to develop methods to address and accelerate students in this category. The course design, to take advantage of the students’ prior experience, emphasizes practice and mastery using a commercial software [1]. The large-scale intervention is a high school course developed by [Author1] for local high schools. Students who have completed their high school mathematics course work but who have not achieved the state’s college readiness standard [2] are targeted. The students in the course have had experience in their high school classes in all of the concepts in the state standard, but have not had the chance to practice and master the material. The course we have developed emphasizes practice and mastery like the small-scale one, but participating school districts could not afford the commercial software. Thus we have built a course around the WebWork software [3] that is available through a free and open license. [1] Assessment and Learning in Knowledge Spaces, https://www.aleks.com/ , McGraw Hill.

Fibrin clot structure remains unaffected in young, healthy individuals after transient exposure to diesel exhaust

Exposure to urban particulate matter has been associated with an increased risk of cardiovascular disease and thrombosis. We studied the effects of transient exposure to diesel particles on fibrin clot structure of 16 healthy individuals (age 21- 44). The subjects were randomly exposed to diesel exhaust and filtered air on two separate occasions. Blood samples were collected before exposure, and 2 and 6 hours after exposure. There were no significant changes on clot permeability, maximum turbidity, lag time, fibre diameter, fibre density and fibrinogen level between samples taken after diesel exhaust exposure and samples taken after filtered air exposure. These data show that there are no prothrombotic changes in fibrin clot structure in young, healthy individuals exposed to diesel exhaust

The Bolocam Galactic Plane Survey IV: 1.1 and 0.35 mm Dust Continuum Emission in the Galactic Center Region

The Bolocam Galactic Plane Survey (BGPS) data for a six square degree region of the Galactic plane containing the Galactic center is analyzed and compared to infrared and radio continuum data. The BGPS 1.1 mm emission consists of clumps interconnected by a network of fainter filaments surrounding cavities, a few of which are filled with diffuse near-IR emission indicating the presence of warm dust or with radio continuum characteristic of HII regions or supernova remnants. New 350 {\mu}m images of the environments of the two brightest regions, Sgr A and B, are presented. Sgr B2 is the brightest mm-emitting clump in the Central Molecular Zone and may be forming the closest analog to a super star cluster in the Galaxy. The Central Molecular Zone (CMZ) contains the highest concentration of mm and sub-mm emitting dense clumps in the Galaxy. Most 1.1 mm features at positive longitudes are seen in silhouette against the 3.6 to 24 {\mu}m background observed by the Spitzer Space Telescope. However, only a few clumps at negative longitudes are seen in absorption, confirming the hypothesis that positive longitude clumps in the CMZ tend to be on the near-side of the Galactic center, consistent with the suspected orientation of the central bar in our Galaxy. Some 1.1 mm cloud surfaces are seen in emission at 8 {\mu}m, presumably due to polycyclic aromatic hydrocarbons (PAHs). A ~0.2\degree (~30 pc) diameter cavity and infrared bubble between l \approx 0.0\degree and 0.2\degree surrounds the Arches and Quintuplet clusters and Sgr A. The bubble contains several clumpy dust filaments that point toward Sgr A\ast; its potential role in their formation is explored.

The Molecular Gas Environment in the 20 KMS−1 Cloud in the Central Molecular Zone

We recently reported a population of protostellar candidates in the 20 kms−1 cloud in the Central Molecular Zone of the Milky Way, traced by H2O masers in gravitationally bound dense cores. In this paper, we report high-angular-resolution (_3′′) molecular line studies of the environment of star formation in this cloud. Maps of various molecular line transitions as well as the continuum at 1.3 mm are obtained using the Submillimeter Array. Five NH3 inversion lines and the 1.3 cm continuum are observed with the Karl G. Jansky Very Large Array. The interferometric observations are complemented with single-dish data. We find that the CH3OH, SO, and HNCO lines, which are usually shock tracers, are better correlated spatially with the compact dust emission from dense cores among the detected lines. These lines also show enhancement in intensities with respect to SiO intensities toward the compact dust emission, suggesting the presence of slow shocks or hot cores in these regions. We find gas temperatures of &100 K at 0.1-pc scales based on RADEX modelling of the H2CO and NH3 lines. Although no strong correlations between temperatures and linewidths/H2O maser luminosities are found, in high-angular-resolution maps we notice several candidate shock heated regions offset from any dense cores, as well as signatures of localized heating by protostars in several dense cores. Our findings suggest that at 0.1-pc scales in this cloud star formation and strong turbulence may together affect the chemistry and temperature of the molecular gas
