Through youth organizing initiatives, young people conduct research into social issues and build power to address these issues. This study examines the developmental interplay between the cognitive components of two of the most influential civic developmental constructs—critical consciousness and psychological empowerment—through analysis of interviews with 19 current and former participants in a youth organizing initiative in San Bernardino, CA, all of whom identify as Latinx. Most participants clearly articulated viewpoints consonant with the cognitive components of critical consciousness and psychological empowerment, but these were much more pronounced among those who had been involved for longer periods of time. Findings provide insights into distinctions and crosscurrents between critical reflection and cognitive empowerment, and into the settings and processes leading to their development. Cycles of action and reflection can support the simultaneous development of critical reflection and cognitive empowerment.

For the first time in nearly 50 years, a population of a nearly extinct frog has been re-discovered in the San Bernardino National Forest’s San Jacinto Wilderness. Biologists from the U.S. Geological Survey (USGS) assessing suitability of sites tore-establish frogs and scientists from the San Diego Natural History Museum retracing a 1908 natural history expedition both rediscovered the rare Mountain Yellow-legged Frog (Rana muscosa) in the San Jacinto Wilderness near Idyllwild, California.

Los bosques templados requieren de un monitoreo periódico con el fin de lograr un manejo sustentable. Los sensores remotos permiten hacer estimaciones de manera indirecta bajo el supuesto de que existe una correlación estadística entre datos satelitales y parámetros forestales. El objetivo del presente trabajo fue estimar el área basal (G), el volumen forestal (Vta) y la biomasa forestal aérea (W) mediante datos espectrales del satélite Sentinel 2A en la Comunidad de San Bernardino de Milpillas Chico, Pueblo Nuevo, Durango. Se realizó un análisis de correlación entre información dasométrica procedente de 22 Sitios Permanentes de Investigación Forestal y de Suelos (SPIFyS) e información espectral de alta resolución del sensor Sentinel 2A. Posteriormente, se generó un modelo de regresión múltiple para cada parámetro forestal. El coeficiente de correlación (r) más alto se observó en el NDVI con valores de 0.77, 0.68 y 0.76 para los parámetros forestales de Vta, G y W, respectivamente. Los modelos desarrollados explicaron 59 % de la varianza total observada en el Vta (RCME=57.60 m3 ha-1), 58 % en W (RCME=39.29 Mg ha-1), y 51 % en G (RCME=4.40 m2 ha-1). El NDVI fue la principal variable predictiva en los tres modelos. Los datos de Sentinel 2A con resolución de 10 m en combinación con información dasométrica derivada de SPIFyS mostraron una buena capacidad para el mapeo de parámetros forestales en bosques templados.

In 2018 the Anthropology Museum at California State University San Bernardino (USA) opened an exhibition entitled In|Dignity. The collaborative endeavour combined social science techniques, documentary photography, and theatre performances to present first person narratives of 43 community members. Participants represented marginalized demographics and intersectional identities that extended far beyond standardized approaches to ‘diversity’. Their stories provided an intimate look into experiences of discrimination, microaggressions, harassment, exclusion, and other affronts to self-worth and barriers to community belonging. This article argues that connecting individuals through telling and listening to stories is a valid strategy to promote social justice. In|Dignity provides one case study of a museum using the narrative form and the processes of exhibition development to disrupt power hierarchies, uplift community concerns, and promote human dignity.

Abstract Background In the U.S., non-Hispanic Black individuals are disproportionately represented amongst COVID-19 mortalities. The COVID-19 vaccines are poised to change this outcome; however, inequitable access and decades of medical mistreatment have resulted in healthcare mistrust and an associated low uptake within this group. Loma Linda University (LLU) houses the largest mass vaccination site in San Bernardino County (SBC) California; nevertheless, there has been a perpetual low representation of Black vaccinees. To increase the number of Black persons vaccinated, a selected team at LLU leveraged a community-academic partnership model to address vaccine hesitancy and increase access to the COVID-19 vaccines. The objective of this study was to evaluate the number of Black persons vaccinated in community settings compared to the mass clinic. Methods LLU developed a tiered approach to increase COVID-19 vaccinations within Black SBC communities. The first tier engaged faith leaders with the academic community in disseminating COVID-19 health information, the second included culturally representative LLU healthcare professionals in the delivery of COVID-19 educational webinars, and the third was to conduct low barrier, remote-site vaccination clinics, within targeted Black communities. Following these efforts, we compared the number of Black individuals vaccinated in the LLU mass clinic to those vaccinated in the community remote-site clinics. Results The remote-site COVID-19 vaccination clinics commenced in February 2021. From February 1 until April 30, 2021, 24,808 individuals were vaccinated in the LLU mass clinic with a first dose (Pfizer or Moderna) or single dose (Janssen) of a COVID-19 vaccine, however, only 908 (3.7%) were Black vaccinees. Contrastingly, the LLU remote site clinics vaccinated 1,542 individuals with a first or single dose of a COVID-19 vaccine. Of those vaccinees, 675 (44%) were Black. Conclusion The multi-tiered community approach (remote-site vaccination clinics) resulted in a necessary overrepresentation of Black vaccinees, previously underrepresented in the LLU traditional mass vaccination clinic effort (44% vs. 3.7%, respectively). Further research is warranted to examine the key elements to increase vaccinations amongst minoritized groups.

This paper explores and contextualizes recent activism in 2019-2020 around Amazon’s San Bernardino airport warehouse expansion. While California has become a nexus for US debates on the rights of gig labour and tech workers, this coalition focused particularly on intersections of worker rights and environmental justice. The highly polluting air cargo centre, they argued, would worsen air quality and constitute environmental racism in the predominantly Hispanic, working-class San Bernardino. This coalition used creative tactics and data practices informed by place-specific histories of economic and environmental activism, to re-imagine algorithmically mediated work and link it to ongoing struggles. Analyzing primary materials and media coverage of this diverse coalition, we find a strategy unified around economic justice, environmental justice, and community benefits. This case study contributes a framework for worker-centric, site-specific analyses of internet technologies and sustainability. By exploring this intersection, we hope to provide insight into building more equitable internet infrastructures and designing technological systems in solidarity with affected communities, workers, and environments.

To determine if there were significant differences produced by 5 of the most prevalent causes of equine enterocolitis, we studied retrospectively the gross and microscopic pathology of 90 cases of enterocolitis submitted to the San Bernardino laboratory of the California Animal Health and Food Safety Laboratory. Included were cases caused by Clostridium perfringens type C (CP; n = 20), Clostridioides difficile (CD; n = 20), Paeniclostridium sordellii (PS; n = 15), Salmonella enterica subspecies enterica serovar Typhimurium (ST; n = 20), and NSAID intoxication (NS; n = 15). Grossly, necrotizing hemorrhagic typhlocolitis was seen most frequently in cases of CD, ST, and NS disease. Cases of CP and PS had enteritis or colitis in similar percentages. Congestion, hemorrhage, and pleocellular inflammatory infiltrates followed by mucosal and submucosal necrosis were the main lesions found in horses with enteritis or colitis produced by any of the etiologic agents investigated. Severe lesions were more frequent in cases of CD and CP than in cases associated with any of the other 3 etiologies. Pseudomembranes were observed with similar prevalence in the small intestine and colon affected by all agents studied. Thrombosis of the lamina propria and/or submucosa was observed in ~50% of the cases of enteritis and colitis by all etiologies, except for PS, in which the majority of the cases had thrombosis. Gross and microscopic lesions of enterocolitis were not sufficiently specific for any of these etiologic agents to enable these enteritides to be distinguished by gross and/or histologic examination.

Four new latest Pleistocene slip rates from two sites along the northwestern half of the San Bernardino strand of the San Andreas fault suggest the slip rate decreases southeastward as slip transfers from the Mojave section of the San Andreas fault onto the northern San Jacinto fault zone. At Badger Canyon, offsets coupled with radiocarbon and optically stimulated luminescence (OSL) ages provide three independent slip rates (with 95% confidence intervals): (1) the apex of the oldest dated alluvial fan (ca. 30–28 ka) is right-laterally offset ~300–400 m yielding a slip rate of 13.5 +2.2/−2.5 mm/yr; (2) a terrace riser incised into the northwestern side of this alluvial fan is offset ~280–290 m and was abandoned ca. 23 ka, yielding a slip rate of 11.9 +0.9/−1.2 mm/yr; and (3) a younger alluvial fan (13–15 ka) has been offset 120–200 m from the same source canyon, yielding a slip rate of 11.8 +4.2/−3.5 mm/yr. These rates are all consistent and result in a preferred, time-averaged rate for the past ~28 k.y. of 12.8 +5.3/−4.7 mm/yr (95% confidence interval), with an 84% confidence interval of 10–16 mm/yr. At Matthews Ranch, in Pitman Canyon, ~13 km northwest of Badger Canyon, a landslide offset ~650 m with a 10Be age of ca. 47 ka yields a slip rate of 14.5 +9.9/−6.2 mm/yr (95% confidence interval). All of these slip rates for the San Bernardino strand are significantly slower than a previously published rate of 24.5 ± 3.5 mm/yr at the southern end of the Mojave section of the San Andreas fault (Weldon and Sieh, 1985), suggesting that ~12 mm/yr of slip transfers from the Mojave section of the San Andreas fault to the northern San Jacinto fault zone (and other faults) between Lone Pine Canyon and Badger Canyon, with most (if not all) of this slip transfer happening near Cajon Creek. This has been a consistent behavior of the fault for at least the past ~47 k.y.
