In this article the authors explore the use of “California,” its translations, and associated phrases in the nine languages collected in the Google Books corpora since 1525. The article graphs the use across time, analyzes the data, and considers some of the reasons behind the peaks and troughs of the usage of “California” and related phrases. For those new to computational corpus analysis, this article introduces the techniques and concepts of corpus analysis, explains the strengths and weaknesses of large-scale, longitudinal studies of language, and describes the specific methods applied in this analysis. Across all languages, the frequency of “California” increases steadily until the late 1990s. The article also examine the use of the notable but infrequently used phrase “California dream.” Visualizations of the analyses accompany the article, as well as additional graphs comparing the use of Los Angeles to San Francisco and Northern California to Southern California since 1800.

Abstract Introduction The COVID-19 pandemic has resulted in societal-level changes to sleep and other behavioral patterns. Objective, longitudinal data would allow for a greater understanding of sleep-related changes at the population level. Methods N= 163,524 deidentified active Fitbit users from 6 major US cities contributed data, representing areas particularly hard-hit by the pandemic (Chicago, Houston, Los Angeles, New York, San Francisco, and Miami). Sleep variables extracted include nightly and weekly mean sleep duration and bedtime, variability (standard deviation) of sleep duration and bedtime, and estimated arousals and sleep stages. Deviation from similar timeframes in 2019 were examined. All analyses were performed in Python. Results These data detail how sleep duration and timing changed longitudinally, stratified by age group and gender, relative to previous years’ data. Overall, 2020 represented a significant departure for all age groups and both men and women (P<0.00001). Mean sleep duration increased in nearly all groups (P<0.00001) by 5-11 minutes, compared to a mean decrease of 5-8 minutes seen over the same period in 2019. Categorically, sleep duration increased for some and decreased for others, but more extended than restricted. Sleep phase shifted later for nearly all groups (p<0.00001). Categorically, bedtime was delayed for some and advanced for others, though more delayed than advanced. Duration and bedtime variability decreased, owing largely to decreased weekday-weekend differences. WASO increased, REM% increased, and Deep% decreased. Additional analyses show stratified, longitudinal changes to sleep duration and timing mean and variability distributions by month, as well as effect sizes and correlations to other outcomes. Conclusion The pandemic was associated with increased sleep duration on average, in contrast to 2019 when sleep decreased. The increase was most profound among younger adults, especially women. The youngest adults also experienced the greatest bedtime delay, in line with extensive school-start-times and chronotype data. When given the opportunity, the difference between weekdays and weekends became smaller, with occupational implications. Sleep staging data showed that slightly extending sleep minimally impacted deep sleep but resulted in a proportional increase in REM. Wakefulness during the night also increased, suggesting increased arousal despite greater sleep duration. Support (if any) This research was supported by Fitbit, Inc.

The Cretaceous and early Cenozoic species of the shallow-marine, warm-water bivalve Plicatula from California (United States) and Baja California (Mexico) are reviewed, and three new species are named. All of these species are representatives of Plicatula and not of the closely related taxon Harpax, which is associated with high-latitude and cool-water regions. The earliestknown Cretaceous species of Plicatula from the study area is P. variata Gabb, 1864, from Lower Cretaceous (Hauterivian Stage) strata in northern California, and our studies show it to be conspecific with Plicatula onoensis Anderson, 1958.Plicatula allisoni new species is from Lower Cretaceous (Albian Stage) strata in Baja California, Mexico. Plicatula modjeskaensis new species is from Upper Cretaceous (Turonian Stage) strata in the Santa Ana Mountains, southern California. A possible new species from the same strata is also mentioned. A poorly preserved specimen of Plicatula? sp. is known from Upper Cretaceous (upper Campanian to lower Maastrichtian) strata in northern California.The only Paleocene species of Plicatula from the study area is P. ostreiformis Stanton, 1896, from lower Paleocene strata of Lake County, northern California, and our studies show it to be conspecific with Ostrea buwaldana Dickerson, 1914. The only previously described Eocene species of Plicatula from the study area is P. juncalensis Squires, 1987, from lower middle Eocene (“Capay Stage”) strata of Los Angeles County, southern California. Plicatula surensis new species is from middle lower Eocene (“Capay Stage”) strata in Baja California Sur, Mexico. In addition, there is a Plicatula? sp. from Eocene strata of Baja California Sur, Mexico.Although Plicatula is of uncommon occurrence north of Baja California, its thermophilic trait makes it useful in recognizing periods of warm climate.

<p>Monitoring temporal changes in seismic wavespeed can inform our understanding of the evolution of crustal rocks’ mechanical state caused by perturbations in stress field, damages, and fluids. Furthermore, imaging these time-lapse changes in space can help unravel the response of rocks with different elastic properties. In this study, we analyze the spatiotemporal variations of seismic wavespeed in Southern California from 2007 to 2017. We compute the Green’s functions by daily cross-correlations using ambient noise at over three hundred broadband seismic stations. Instead of calculating simply the linear regressions of travel-time shifts over lag-times, which only resolves homogeneous changes, we scrutinize the variations of travel-time shifts at different lag-times and frequencies using coda-wave sensitivity kernels, in order to probe the spatial distribution of wavespeed changes. The long-term and large-scale analysis allows us to investigate the mechanical response of different crustal materials to various transient processes. As an example we use the 2010 Mw 7.2 El Mayor-Cucapah Earthquake (EMC) and show that large coseismic wavespeed reductions occur in Salton Sea area and the Los Angeles sedimentary basin. In the latter region, the ground motion amplification and high susceptibility of sedimentary materials explain the remote signature of the earthquake. In the Salton Sea region, particularly in the geothermal area with highly pressurized fluids, the non-linear crustal response illustrated by wavespeed changes can be analyzed with regard to the high-level micro-seismicity triggered by EMC.</p>

SAN FRANCISCO, Nov. 11 (AP)—Blood donated by family members and friends is more likely to carry hepatitis and some other diseases than is blood from anonymous donors, a Government study has found... The study, financed by the National Institutes of Health, is the first large-scale examination of the safety of directed donations, Mr. Williams said. It involved examination of the records of 1,099,341 donations by 699,702 donors in Los Angeles, Oklahoma City, Detroit, San Francisco and the Baltimore-Washington area. One screening test showed that 2.6 percent of donations from friends and relatives were infected with hepatitis B, compared with 1.8 percent of blood-bank donations, Mr. Williams said. Donations from friends and family members were also more likely to be contaminated with hepatitis C, syphilis and a virus HTLV-1, that can cause cancer.

California is regularly impacted by floods and droughts, primarily as a result of too many or too few atmospheric rivers (ARs). This study analyzes a two-decade-long hourly precipitation dataset from 176 California weather stations and a 3-hourly AR chronology to report variations in rainfall events across California and their association with ARs. On average, 10-40 and 60-120 hours of rainfall in southern and northern California, respectively, are responsible for more than half of annual rainfall accumulations. Approximately 10-30% of annual precipitation at locations across the state is from only one large storm. On average, northern California receives 25-45 rainfall events annually (40-50% of which are AR-related). These events typically have longer durations and higher event-precipitation totals than those in southern California. Northern California also receives more AR landfalls with longer durations and stronger Integrated Vapor Transport (IVT). On average, ARs contribute 79%, 76%, and 68% of extreme-rainfall accumulations (i.e., top 5% events annually) in the north coast, northern Sierra, and Transverse Ranges of southern California, respectively. The San Francisco Bay Area terrain gap in the California Coast Range allows more AR water vapor to reach inland over the Delta and Sacramento Valley, and thus, influences precipitation in the Delta’s catchment. This is particularly important for extreme precipitation in the northern Sierra Nevada, including river basins above Oroville Dam and Shasta Dam. This study highlights differences between rainfall and AR characteristics in coastal versus inland northern California, differences that largely determine the regional geography of flood risks and water-reliability. These analyses support water resource, flood, levee, wetland, and ecosystem management within the catchment of the San Francisco estuary system by describing regional characteristics of ARs and their influence on rainfall on an hourly timescale.

Filipino festivals (also “Philippine festivals”) in southern California are lively, dynamic events that draw multigenerational and multicultural crowds to enjoy food, partake in traditional games and crafts, buy Filipino pride gear, and watch a variety of acts that showcase the talent and creativity of Filipino Americans. Inclusive of those who identify as immigrant, U.S.-born, and transnational, Filipinos from across the region convene to express pride and promote visibility as an overlooked and marginalized ethnic group in the United States. The first public performances by Filipinos in the United States were in exhibits curated by colonial officials at the St. Louis World’s Fair in 1904 to justify colonization of the Philippines. Presented as an uncivilized people in need of American tutelage, this stereotyping of Filipinos as primitives motivated pensionados or students from the Philippines to represent themselves; they organized Rizal Day starting in 1905, which valorized national Philippine hero José Rizal, in order to highlight their identity as modern, educated people. New immigrants, who were mostly rural, single men from the northern Philippines, arrived in the 1930s and frequented taxi dance halls in which Filipino jazz musicians and dancers flourished. Yet the established Filipino community criticized these venues as places of vice that were lacking in family and traditional cultural values. Philippine folk dances were not prevalent among Filipino Americans until after the Philippine Bayanihan Folk Dance Company appeared on the Ed Sullivan Show in 1958. Due to their influence, Filipino American folk dance troupes were established across the nation, presenting Philippine cultures through stylistically diverse dances such as the Indigenous or Tribal suite, the Muslim or “Moro” suite, and the Maria Clara or Spanish-influenced suite. Folk dance performance became a hallmark of festivals such as the Philippine Folk Festival, which has been held annually in San Diego since 1979 (renamed the Philippine Cultural Arts Festival in 1996). In Los Angeles, the Festival of Philippine Arts and Culture began in 1992, attracting thousands from around the region. These large-scale public Filipino festivals in southern California offer opportunities to gain insight into the variety of ways in which Filipino Americans creatively express a range of experiences, interests, and concerns. While folk dance troupes and traditional music ensembles such as Spanish-influenced rondalla (plucked string instruments) are most visibly tied to representations of Philippine traditions, rappers, DJs, spoken word artists, hip-hop dance crews, R&B singers, and rock bands demonstrate Filipinos’ mastery of American popular forms. With origins in community celebrations since the early 1900s, Filipino festivals of the early 21st century reflect changes and continuities in California’s Filipino communities, which have adapted to internal dynamics, larger societal forces, and engagement with the homeland of the Philippines.

Regulatory requirements and social constraints make it necessary to evaluate the environmental effects of a project and to incorporate into the design features to minimize adverse environmental impacts. This paper presents a case history of efforts to meet these requirements for a coastal power plant in southern California, Southern California Edison Company and San Diego Gas & Electric Company are jointly now constructing two additional units to the existing San Onofre Nuclear Generating Station, Being added are Units 2 and 3, The site, about 84 acres (34 ha,), is located within Camp Pendleton, a United States Marine Corps Base, about halfway between San Diego and Los Angeles, Califoria, The site (See Figure 1) is situated on the edge of a narrow coastal plain that extends from the coastline to a range of low hills, two miles inland, that have a maximum elevation of 1,725 feet (525 m) above sea level. The plain terminates at the beach in a line of wave-straightened cliffs, extending 60 to 80 feet (18 to 24m) above a narrow sandy beach. Numerous ravines are cut into the cliffs as a result of erosion by storm runoff from the coastal plain, Oceanographic features at the San Onofre site include a sandy bottom which slopes gradually to a depth of 60 feet (18 m) at about 10,000 feet (3,000 m) offshore. Mean maximum summer surface water temperature is about 73°F (23°C). During the fall and winter the water column is usually thermally homogeneous with a minimum temperature of approximately 56°F (13°C). Ocean currents at the site are chiefly tidally induced, although large scale low velocity circulation patterns are generally present. Very near to the southern California coast, local currents are influenced primarily by a combination of wind, tide, and local topography. The total current is ordinarily the sum of components due to wind, tide, and perhaps large-scale ocean circulations. Speed of the total current measured at San Onofre typically ranges from 0.10 to 1,75 knots, but averages 0.2 knots. San Onofre, Units 2 and 3 are being constructed southeast of, and immediately adjacent to existing Unit 1. Both the existing and the units under construction generate electrical power by using pressurized water nuclear reactors. Unit 1 has a capacity of 450 MWe and began commercial operation in 1968, Units 2 and 3 will each have a rated electrical output of 1,100 MWe. Commercial operation of Unit 2 is scheduled to begin in October 1981, and Unit 3 in January of 1983,
