One Builds the Bridge: Structures for Serving First Generation Students with Information Literacy Instruction

Colleges and universities designated as Hispanic Serving Institutions (HSI) struggle to demonstrate \u27servingness\u27 within the existing structures of higher education. Librarians welcoming and engaging first generation students can integrate Garcia\u27s multidimensional framework for servingness into information literacy instruction by focusing on culturally relevant pedagogy as a structure for serving students. This workshop will explore instruction aimed towards first-generation graduate students at HSIs, focusing on characteristics such as social capital. Presenters will discuss specific research-based instructional strategies such as high impact practices and leave attendees equipped with tools to promote action.Participants will be able to:1. understand the characteristics of Hispanic Serving Institutions and the multidimensional model of servingness. 2. adapt strategies discussed to enhance information literacy instruction for all students, particularly graduate students from historically marginalized groups

Collecting First-Generation Voices in Academic Libraries and Archives

First-generation college students have a profound impact both inside and outside the classroom on the strategic goals of universities, yet in-depth, firsthand information about their experiences are difficult for researchers and university administrators to find. Oral histories are a data-rich method of collecting narratives that legitimize the perspectives of underrepresented communities whose stories are often absent from the written record. This article provides a brief overview of first-generation populations, a review of literature relating to the increasing involvement of libraries and archives in capturing and preserving the stories of underdocumented communities in the twenty-first century, and shares three case studies of first-generation initiatives at public universities in California, Colorado, and Nebraska

Digital psychology: reflections on the study of human behavior in the information technology era

La transformación digital es un tema vigente de gran importancia debido a la amplitud con la que está afectando la vida de las personas a nivel global. Se presentan reflexiones sobre la modificación del comportamiento que está teniendo lugar durante este proceso. Sobre todo, la tecnología digital ha impulsado una interacción algorítmica que ha provocado un incremento en la necesidad de una alfabetización digital en las personas para mantenerse funcional en el contexto cotidiano y enfatizado la necesidad de un enfoque en solución de problemas en la educación superior con miras a sostener el funcionamiento social digitalizado. Se propone que se debe hacer un esfuerzo investigativo para acompañar el proceso de desarrollo de competencias digitales en esta transición a los mundos compuestos y compartidos.Digital transformation is a current topic of great importance due to the extent to which it is affecting the lives of people globally. Reflections on the behavior modification that is taking place during this process are presented. Above all, digital technology has promoted an algorithmic interaction that has caused an increase in the need for digital literacy in people to remain functional in the daily context and emphasized the need for a problem-solving approach in higher education with a view to sustain digitized social functioning. It is proposed that a research effort should be made to accompany the process of developing digital skills in this transition to composite and shared worlds

Potencial alelopático de cinco espécies da família Annonaceae

Allelopathy refers to the ability that certain plant has to interfere in the metabolism of another by substances released into the environment, causing harmful or beneficial effects. The aim of this work was to evaluate the allelopathic effects of metanolic extracts from shoots (leaves and stems) of Annona crassiflora, A. coriacea, A. dioica, A. sylvatica and Duguetia furfuracea (Annonaceae), at 1% (m/v) concentration on germination and early growth of lettuce seedlings. Treatments consisted of three replicates of 25 lettuce seeds distributed in Petri dishes containing two sheets of germitest paper and 3 mL of extracts, maintained at 25ºC with white light. The control treatment was only watered with distilled water. The counting of normal seedlings, time of germination and length of radicle and hypocotyl were evaluated at four and seven days after sowing. Extracts were characterized about pH and phytochemical prospection. The methanolic extracts from Annonaceae altered all the parameters analyzed, significantly reducing the germination percentage and vigor of lettuce seeds and affecting adversely the time of germination in relation to the control. Extracts also caused radicle and hypocotyls growth inhibition.Alelopatia se refere à capacidade que determinada planta tem de interferir no metabolismo de outra, por meio de substâncias liberadas no ambiente, causando efeitos danosos ou benéficos. O objetivo deste trabalho foi avaliar os efeitos alelopáticos de extratos metanólicos da parte aérea (folhas e caules) de Annona crassiflora, A. coriacea, A. dioica, A. sylvatica e Duguetia furfuracea (Annonaceae), na concentração de 1% (m/v) sobre a germinação e no crescimento inicial de plântulas de alface. Os testes foram realizados em triplicatas com 25 sementes de alface distribuídas em placas de Petri contendo duas folhas de papel germitest e 3 mL dos extratos, mantidas a 25ºC sob luz branca constante. Água destilada foi utilizada no tratamento controle. A contagem das plântulas normais, o tempo médio de germinação e comprimento de radícula e de hipocótilo foram avaliados aos quatro e sete dias após a semeadura. Os extratos foram caracterizados quanto ao pH e perfil fitoquímico. Os extratos metanólicos das plantas de Annonaceae alteraram todos os parâmetros analisados, reduzindo significativamente a porcentagem de germinação e o vigor de sementes de alface, além de afetarem negativamente o tempo médio de germinação em relação ao controle. Os extratos também causaram inibições no comprimento radicular e de hipocótilo

Hypofractionated radiotherapy in postmastectomy locally advanced breast cancer: an interim report on acute toxicities and dosimetry

Background: There is a growing interest in the use of hypofractionation in the setting of post-mastectomy radiation therapy (PMRT). Here, we present an interim report on the acute toxicities and the dosimetry of a 15-day hypofractionated regimen. Materials and methods: Patients aged 18–75 years who underwent mastectomy and had pathological stage IIB–IIIC or any clinical stage who had received neoadjuvant chemotherapy were treated with PMRT at a dose of 43.5 Gy in 15 fractions. Acute toxicities were scored using Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Results: Between September 2020 and September 2021, 92 patients were enrolled in the study. Majority experienced grade 1 dermatitis during the course of treatment. Skin toxicities peaked two weeks after PMRT in which 57 patients (62%) had grade 2 dermatitis and 6 patients (7%) had grade 3 dermatitis. Most resolved one month after treatment, with all resolving at three months. Grade 2 fatigue occurred in 4 patients (4%). There were no grade 3 fatigue or pneumonitis of any grade. The average V95% for the chest wall, axilla, and supraclavicular fossa were 91.5%, 99.3%, and 97.5%, respectively. Average ipsilateral lung V17 was 43.6%, while the mean heart dose averaged at 3.46 Gy. Conclusion: This interim report showed that hypofractionated PMRT is associated with a low incidence of clinically significant acute toxicities. With the use of the 3-dimensional conformal radiotherapy technique and volume-based planning, adequate target volume coverage and acceptable heart doses were achieved, although with a slightly higher ipsilateral lung dose

Antiobesity Effects of Hydroethanolic Extract of Jacaranda decurrens

Obesity is a worldwide epidemic that reduces life expectancy; therefore, the search for new alternative and effective treatments is ongoing. The aim of the present investigation was to identify the chemical compounds in the hydroethanolic extract of leaves of Jacaranda decurrens subsp. symmetrifoliolata and to evaluate their toxicity and antiobesity effects. High-performance liquid chromatography was used to identify the chemical constituents, and acute toxicity was evaluated in rats treated with doses of 2 and 5 g·kg−1 body mass. The antiobesity effect was determined in rats with hypercaloric diet-induced obesity. Our results revealed the presence of compounds, such as jacaric, ursolic, and oleic acids, as well as luteolin, quercetin, and kaempferol, in the extract. The acute toxicity tests revealed that rats treated with elevated doses of the extract showed no signs of toxicity. The extract induced reduction in total body mass and the white adipose tissue depots. The obese rats treated with the extract showed an increased fluid intake and feces excretion while their serum total cholesterol and triglyceride levels decreased compared to those in the controls, without any hematological changes. Taken together, the results showed that the constituents of J. decurrens extracts included phenolic compounds and exhibited antiobesity effects with no toxicity

Estrategias combinadas para la obtención de un vino Tannat con un contenido moderado de alcohol

Resumen En este trabajo se buscó a través de la combinación de 2 estrategias reducir el contenido de alcohol en vinos de la variedad Tannat. La primera estrategia consistió en el screening dentro de clones uruguayos de Tannat Con este fin se muestrearon durante tres vendimias consecutivas 10 clones uruguayos de Tannat y se utilizó como referencia el clon francés 717 en viñedos. De los clones estudiados 4 presentaron durante la vendimia 2023 un contenido significativamente inferior de alcohol que el clon 717, manteniendo los componentes responsables de su calidad sensorial (aromas glicosidados, antocianos totales). Mientras que la segunda estrategia fue realizar un screening de levaduras no-Saccharomyces nativas aisladas de viñedos uruguayos para utilizar en conjunto con la cepa Saccharomyces cerevisiae Lalvin BM4x4 Lalleman (utilizada como referencia para vinificar vino Tannat). Se estudió el comportamiento de 4 géneros de levaduras (Candida zemplinina, Metschnikowia pulcherrima, Metschnikowia fructicola y Hanseniaspora uvarum), en microvinificaciones en símil vino. Estas estrategias fueron seleccionada por que además de permitir la reducción de alcohol en vinos Tannat en forma conjunta le aportan una identidad propia de nuestro país
