El Instituto: Centering Language, Culture, and Power in Bilingual Teacher Professional Development

Teacher education programs have the obligation to prepare bilingual teachers, new and established, to challenge pervasive deficit and racist ideologies, to cultivate students’ identities/knowledges, and to thwart oppressive ideologies through counter-hegemonic discourses. This paper presents a case study of El Instituto, one Hispanic Serving Institution’s immersive professional development program for Spanish-speaking bilingual teachers in Los Angeles County. Conducted entirely in Spanish, the program aimed to center teachers’ sociocultural realities and community cultural wealth while honoring their linguistic capital, deepening their Spanish-language knowledge, and developing critical consciousness. Findings suggest that utilizing a sociocultural approach to simultaneously study Spanish language and critical pedagogy while centering teachers’ community cultural wealth led to deep insights about intersections of languages and culture within larger power structures that cultivate systemic oppression. However, epistemological shifts about fostering more humanizing and critical professional development for bilingual educators are necessary to achieve these goals

La violencia intrafamiliar y su influencia en el logro de aprendizajes de los estudiantes de un ceba del distrito de Otuzco, 2020

Este estudio se realizó para describir cómo la violencia intrafamiliar influye en el logro de aprendizajes de los educandos de un CEBA del distrito de Otuzco. En cuanto a la metodología, se desarrolló bajo el enfoque cualitativo, donde se empleó el método inductivo y de acuerdo a su objetivo es de tipo fenomenológico, de modo que, se llegó a entender las vivencias de los participantes en cuanto a la violencia intrafamiliar y de qué manera impactan en el logro de sus aprendizajes. Las participantes fueron 6 estudiantes del 1° y 2° ciclo del CEBA del distrito de Otuzco, los cuales fueron evaluados mediante entrevistas focalizadas. En los resultados se encontró que tres adolescentes señalan a sus padres como quienes imponen las reglas en el hogar, asimismo, dos de ellas señalan que sus parejas son quienes cumplen esa función y dos de las participantes son excluidas por sus suegras en la toma de decisiones, del mismo, en la involucración y responsabilidad familiar en cuanto a los asuntos académicos de las adolescentes, existe comunicación con la tutora por iniciativa de la misma mas no de los padres. En tres casos cuentan con sus tías quienes las motivan a continuar con sus estudios. Se logró concluir que la violencia intrafamiliar influye en el logro de aprendizajes de las alumnas de un CEBA del distrito de Otuzco, perjudicando sus emociones y motivaciones, además de su atención y concentración, como resultado no priorizan un tiempo para realizar sus actividades académicas.Tesi

Analysis of Hendra Virus Fusion Protein N-Terminal Transmembrane Residues

Hendra virus (HeV) is a zoonotic enveloped member of the family Paramyoxviridae. To successfully infect a host cell, HeV utilizes two surface glycoproteins: the attachment (G) protein to bind, and the trimeric fusion (F) protein to merge the viral envelope with the membrane of the host cell. The transmembrane (TM) region of HeV F has been shown to have roles in F protein stability and the overall trimeric association of F. Previously, alanine scanning mutagenesis has been performed on the C-terminal end of the protein, revealing the importance of β-branched residues in this region. Additionally, residues S490 and Y498 have been demonstrated to be important for F protein endocytosis, needed for the proteolytic processing of F required for fusion. To complete the analysis of the HeV F TM, we performed alanine scanning mutagenesis to explore the residues in the N-terminus of this region (residues 487–506). In addition to confirming the critical roles for S490 and Y498, we demonstrate that mutations at residues M491 and L492 alter F protein function, suggesting a role for these residues in the fusion process

La soberanía alimentaria: Cultivando nuevas alianzas entre campo, bosque y ciudad

In June, 2008, we convoked a forum and workshop in Chiapas, Mexico to strengthen alliances among farmers’ organizations, conservationists and academics. Speakers outlined the evolution of the relations among production systems, forests and biodiversity from the prehispanic era through the current crisis in the neoliberal economic model and industrial agriculture. They also framed a new conservation paradigm that prioritizes the role of farmers. We formed working groups that elaborated proposals for collaboration among the participating sectors. Cooperative networks emerged as appropriate structures for coordinating action and facilitating the exchange of information and support at various geographic scales. Solidarity-based markets are a venue where diverse interests converge, favoring the formation of such networks. We also identified some specific issues for collaboration, including: agrofuels and energy sovereignty, environmental services and rural education. Biodiversity and food sovereignty are the two axes of this agenda for cooperation that forms part of an international struggle to reconstruct our food systems.En junio de 2008 convocamos un foro-taller en Chiapas, México para potencializar alianzas entre organizaciones campesinas, conservacionistas y académicos. Los ponentes trazaron la evolución de las relaciones entre sistemas productivos, bosques y biodiversidad desde la época prehispánica hasta la actual crisis de la economía neoliberal y la agricultura industrial. También delinearon un nuevo paradigma para la conservación en donde los campesinos son protagonistas. En grupos de trabajo, elaboramos propuestas para cimentar una agenda común entre los distintos sectores representados. Las redes de cooperación emergieron como estructuras para coordinar acción y facilitar el intercambio de información y apoyo a distintas escalas geográficas. Los mercados solidarios son la confluencia de diversos intereses en dónde se pueden constituir dichas redes. También identificamos algunos temas específicos de trabajo, entre ellos: los agrocombustibles y la soberanía energética, los servicios ambientales y la educación para el campo. La biodiversidad y la soberanía alimentaria y territorial son los ejes de esta agenda de cooperación, que forma parte de una lucha internacional para reconstruir nuestros sistemas alimenticios

Persistent Exposure to Mycoplasma Induces Malignant Transformation of Human Prostate Cells

Recent epidemiologic, genetic, and molecular studies suggest infection and inflammation initiate certain cancers, including those of the prostate. The American Cancer Society, estimates that approximately 20% of all worldwide cancers are caused by infection. Mycoplasma, a genus of bacteria that lack a cell wall, are among the few prokaryotes that can grow in close relationship with mammalian cells, often without any apparent pathology, for extended periods of time. In this study, the capacity of Mycoplasma genitalium, a prevalent sexually transmitted infection, and Mycoplasma hyorhinis, a mycoplasma found at unusually high frequency among patients with AIDS, to induce a malignant phenotype in benign human prostate cells (BPH-1) was evaluated using a series of in vitro and in vivo assays. After 19 weeks of culture, infected BPH-1 cells achieved anchorage-independent growth and increased migration and invasion. Malignant transformation of infected BPH-1 cells was confirmed by the formation of xenograft tumors in athymic mice. Associated with these changes was an increase in karyotypic entropy, evident by the accumulation of chromosomal aberrations and polysomy. This is the first report describing the capacity of M. genitalium or M. hyorhinis infection to lead to the malignant transformation of benign human epithelial cells and may serve as a model to further study the relationship between prostatitis and prostatic carcinogenesis

Placemaking through community and adaptable design (The Case of Coffee Park) (First Design Iteration).

Using participatory planning and community design methodologies (i.e. open planning, pattern language design, placemaking, community planning charrettes, planning-in-situ and wikiplanning) this project explores solutions to revitalize Coffee Park -- a small park along the CN railway in West Montreal. This is a complex site that shows issues of unsafety, lack of mobility and sense of place. The objective of this project is to integrate the park to its larger urban context to improve the mobility, safety and overall quality of life in this public space. After a series of visioning workshops, brainstorming sessions, two community planning charrettes and an open planning exercise, this project incorporates inputs from stakeholders, students and ordinary citizens into a collaborative urban design project. The project proposes strategies of urban re-stitching and regeneration through adaptable design and open community planning.

Quantitative 18F-AV1451 Brain Tau PET Imaging in Cognitively Normal Older Adults, Mild Cognitive Impairment, and Alzheimer's Disease Patients

Recent developments of tau Positron Emission Tomography (PET) allows assessment of regional neurofibrillary tangles (NFTs) deposition in human brain. Among the tau PET molecular probes, 18F-AV1451 is characterized by high selectivity for pathologic tau aggregates over amyloid plaques, limited non-specific binding in white and gray matter, and confined off-target binding. The objectives of the study are (1) to quantitatively characterize regional brain tau deposition measured by 18F-AV1451 PET in cognitively normal older adults (CN), mild cognitive impairment (MCI), and AD participants; (2) to evaluate the correlations between cerebrospinal fluid (CSF) biomarkers or Mini-Mental State Examination (MMSE) and 18F-AV1451 PET standardized uptake value ratio (SUVR); and (3) to evaluate the partial volume effects on 18F-AV1451 brain uptake.Methods: The study included total 115 participants (CN = 49, MCI = 58, and AD = 8) from the Alzheimer's Disease Neuroimaging Initiative (ADNI). Preprocessed 18F-AV1451 PET images, structural MRIs, and demographic and clinical assessments were downloaded from the ADNI database. A reblurred Van Cittertiteration method was used for voxelwise partial volume correction (PVC) on PET images. Structural MRIs were used for PET spatial normalization and region of interest (ROI) definition in standard space. The parametric images of 18F-AV1451 SUVR relative to cerebellum were calculated. The ROI SUVR measurements from PVC and non-PVC SUVR images were compared. The correlation between ROI 18F-AV1451 SUVR and the measurements of MMSE, CSF total tau (t-tau), and phosphorylated tau (p-tau) were also assessed.Results:18F-AV1451 prominently specific binding was found in the amygdala, entorhinal cortex, parahippocampus, fusiform, posterior cingulate, temporal, parietal, and frontal brain regions. Most regional SUVRs showed significantly higher uptake of 18F-AV1451 in AD than MCI and CN participants. SUVRs of small regions like amygdala, entorhinal cortex and parahippocampus were statistically improved by PVC in all groups (p < 0.01). Although there was an increasing tendency of 18F-AV-1451 SUVRs in MCI group compared with CN group, no significant difference of 18F-AV1451 deposition was found between CN and MCI brains with or without PVC (p > 0.05). Declined MMSE score was observed with increasing 18F-AV1451 binding in amygdala, entorhinal cortex, parahippocampus, and fusiform. CSF p-tau was positively correlated with 18F-AV1451 deposition. PVC improved the results of 18F-AV-1451 tau deposition and correlation studies in small brain regions.Conclusion: The typical deposition of 18F-AV1451 tau PET imaging in AD brain was found in amygdala, entorhinal cortex, fusiform and parahippocampus, and these regions were strongly associated with cognitive impairment and CSF biomarkers. Although more deposition was observed in MCI group, the 18F-AV-1451 PET imaging could not differentiate the MCI patients from CN population. More tau deposition related to decreased MMSE score and increased level of CSF p-tau, especially in ROIs of amygdala, entorhinal cortex and parahippocampus. PVC did improve the results of tau deposition and correlation studies in small brain regions and suggest to be routinely used in 18F-AV1451 tau PET quantification
