Validation Theory and Culturally Relevant Curriculum in the Information Literacy Classroom
In four separate undergraduate information literacy classes where students predominantly identified as Latinx, two instruction library faculty revamped the standard information literacy curriculum to emphasize Latinx scholarship. They affirmed student life experience as authority in order to understand how validation theory affects the student scholar identity of first year Latinx college students from a large metropolitan area in the U.S.-Mexico border region. The two librarians who designed and team-taught these information literacy sessions are also both Latinx and come from urban borderlands backgrounds. Both identify as first-generation college students and one identifies as having a mixed status family background

UNIVERSIDAD Y PLANIFICACIÓN ESTRATÉGICA EN EL ECUADOR
Approach to strategic planning is an urgent requirement in the Ecuadorian educational system; special attention deserves the University for its proactive and anticipating needs and changes character. This transformation will not be provided without the necessary strategic intention that must pass to become part of the organizational culture of managers and institutions. Higher education strategic planning is a process highly inclusive, systemic, opened to criticism, where it does not discriminate any process, organized in various times or stages, which allows you to develop, among others, objectives and strategies in different time horizons, which need external and internal information responds to the demands of the environment and of the institution itself, and whose results require follow-up and constant evaluation to ensure the fulfillment of the goals. The identification, definition and improvements of processes and procedures are articulated to an inevitable developmental strategic intention that guarantees the achievement of a dynamic of continuous improvement but they must own a benchmark implicit in the Mission of the educational organization, which cannot be based in the decision and the future of one or several leaders display if not in the prospective study which is obtained by determining the relevance of different disciplines and institutions.
El abordaje de la planificación estratégica es un requerimiento impostergable en el sistema educativo ecuatoriano, especial atención merece la universidad por su carácter proactivo y anticipador de necesidades y cambios. Esta transformación no podrá concretarse sin la necesaria intención estratégica que debe pasar a formar parte de la cultura organizacional de los directivos y las instituciones. La planificación estratégica en la educación superior es un proceso altamente inclusivo, sistémico, aperturado a la crítica, donde no se discrimina ningún proceso, organizado en varios momentos o fases que permite formular, entre otros, objetivos y estrategias en diferentes horizontes de tiempo, que necesita información externa e interna, responde a las demanda del entorno y de la propia institución, y cuyos resultados requieren de seguimiento y evaluación constante que asegure el cumplimiento de las metas trazadas. La identificación, definición y perfeccionamientos de procesos y procedimientos van articulados a una inevitable intención estratégica desarrollista que garantiza la consecución de una dinámica de mejoras continuas pero estas tienen que poseer un referente implícito en la misión de la organización educacional, la cual no puede basarse en la decisión y visualización del futuro de uno o varios líderes si no en el estudio prospectivo que se obtiene determinando la pertinencia de las distintas especialidades e instituciones
Symbolic powers of monomial ideals and Cohen-Macaulay vertex-weighted digraphs
In this paper we study irreducible representations and symbolic Rees algebras
of monomial ideals. Then we examine edge ideals associated to vertex-weighted
oriented graphs. These are digraphs having no oriented cycles of length two
with weights on the vertices. For a monomial ideal with no embedded primes we
classify the normality of its symbolic Rees algebra in terms of its primary
components. If the primary components of a monomial ideal are normal, we
present a simple procedure to compute its symbolic Rees algebra using Hilbert
bases, and give necessary and sufficient conditions for the equality between
its ordinary and symbolic powers. We give an effective characterization of the
Cohen--Macaulay vertex-weighted oriented forests. For edge ideals of transitive
weighted oriented graphs we show that Alexander duality holds. It is shown that
edge ideals of weighted acyclic tournaments are Cohen--Macaulay and satisfy

YSE-PZ: A Transient Survey Management Platform that Empowers the Human-in-the-Loop
The modern study of astrophysical transients has been transformed by an
exponentially growing volume of data. Within the last decade, the transient
discovery rate has increased by a factor of ~20, with associated survey data,
archival data, and metadata also increasing with the number of discoveries. To
manage the data at this increased rate, we require new tools. Here we present
YSE-PZ, a transient survey management platform that ingests multiple live
streams of transient discovery alerts, identifies the host galaxies of those
transients, downloads coincident archival data, and retrieves photometry and
spectra from ongoing surveys. YSE-PZ also presents a user with a range of tools
to make and support timely and informed transient follow-up decisions. Those
subsequent observations enhance transient science and can reveal physics only
accessible with rapid follow-up observations. Rather than automating out human
interaction, YSE-PZ focuses on accelerating and enhancing human decision
making, a role we describe as empowering the human-in-the-loop. Finally, YSE-PZ
is built to be flexibly used and deployed; YSE-PZ can support multiple,
simultaneous, and independent transient collaborations through group-level data
permissions, allowing a user to view the data associated with the union of all
groups in which they are a member. YSE-PZ can be used as a local instance
installed via Docker or deployed as a service hosted in the cloud. We provide
YSE-PZ as an open-source tool for the community.Comment: 23 pages, 9 figures, submitted to PAS
Relapse of unusual localization of classic seminoma with post-chemotherapy transformation
Germ cell tumor is the most common cancer among males in the 20–39 year-old age range, representing 21% of invasive cancer diagnose. The vast majority of testicular tumors in this age range are germ cell tumors. There are two types of malignant tumors, the pure seminoma cell and non-seminomatous germinal cell tumors (NGCT). We present the case of a patient who underwent a testicular tumor surgery, classic seminoma stage I, receiving two cycles of adjuvant carboplatin chemotherapy. During the follow up, an elevation on the alpha-fetoprotein level was observed, thus the final diagnosis was adenopatic recurrence of the Yolk Sac tumor.-----------------------------------------------------------------Cite this article as: Urena MD, Legeren M, Galvez F, Villaescusa A, Aparicio J, Jurado JM, Blancas I, Sanchez MJ, Romera AL, Martinez AP, Quiñonez E, Dulcey I, Puche JL.

Body indices and basic vital signs in Helicobacter pylori positive and negative persons
It has been hypothesized that Helicobacter pylori (Hp) infection may contribute to reduced stature, risk of hypertension or obesity. The aim was to evaluate body indices in Hp positive and negative persons. A total of 2436 subjects (4–100 years old) were tested for Hp status by 13Curea breath test. Data on height and weight were collected for 84%, and blood pressure for 80% of the study subjects. The prevalence of Hp infection was 41.6%. The odds ratio for a 10-year increase in age was 1.21 (95% CI 1.17–1.25, p-value <0.001). Statistically significant negative association of Hp positivity with body height was most pronounced in the younger age groups, while a positive association of Hp positivity with body mass index was only seen in those aged 15+ years. There was a negative effect of Hp positivity on systolic and diastolic blood pressure in subjects below 25 and a relatively strong positive effect on blood pressure in subjects over 65 years. Residual confounding by social characteristics as a possible explanation for the associations of Hp positivity with height and blood pressure cannot be excluded. Unmeasured factors related to social and family environment may cause the apparent association between Hp positivity and children’s growth and blood pressure
Liver surgery in the presence of cirrhosis or steatosis: Is morbidity increased?
<p>Abstract</p> <p>Background data</p> <p>The prevalence of steatosis and hepatitis-related liver cirrhosis is dramatically increasing together worldwide. Cirrhosis and, more recently, steatosis are recognized as a clinically important feature that influences patient morbidity and mortality after hepatic resection when compared with patients with healthy liver.</p> <p>Objective</p> <p>To review present knowledge regarding how the presence of cirrhosis or steatosis can influence postoperative outcome after liver resection.</p> <p>Methods</p> <p>A critical review of the English literature was performed to provide data concerning postoperative outcome of patients presenting injured livers who required hepatectomy.</p> <p>Results</p> <p>In clinical studies, the presence of steatosis impaired postoperative outcome regardless the severity and quality of the hepatic fat. A great improvement in postoperative outcome has been achieved using modern and multidisciplinary preoperative workup in cirrhotic patients. Due to the lack of a proper classification for morbidity and a clear definition of hepatic failure in the literature, the comparison between different studies is very limited. Although, many surgical strategies have been developed to protect injured liver surgery, no one have gained worldwide acceptance.</p> <p>Conclusion</p> <p>Surgeons should take the presence of underlying injured livers into account when planning the extent and type of hepatic surgery. Preoperative and perioperative interventions should be considered to minimize the additional damage. Further randomized trials should focus on the evaluation of novel preoperative strategies to minimize risk in these patients. Each referral liver center should have the commitment to report all deaths related to postoperative hepatic failure and to use a common classification system for postoperative complications.</p
