California Association of School Psychologists (CASP) adopted a Position Paper in March, 2014 intended to support school psychologists in California in electing to use a process known as Patterns of Strengths and Weaknesses (PSW) as one of three methods specified in IDEA 2014 and California Code of Regulations, Title 5, to identify students being assessed for Specific Learning Disability (SLD). The CASP Position Paper recommends use of a Multi-Tiered System of Supports (MTSS) for assisting students who are experiencing learning difficulties. Suggested methods include a comprehensive evaluation using data from multiple sources such as response to instruction and intervention, direct observations across time and settings, record reviews, interviews, and direct assessment to identify the student's strengths and weaknesses in cognitive and academic skill areas. Critical elements of the PSW model are described.

This brief article examines the community services delivered to youth with autism spectrum disorder (ASD) in a Southern Californian city as a way to better understand ASD service provision and service attitudes. Specific goals of the study were to identify the services being delivered within the area, and how the use, perceived evidence, and value attached to these services mapped onto recent systematic ASD service reviews. Forty-six providers completed the ASD Strategies and Interventions Survey (ASD-SIS), which consisted of 21 treatment strategies and 22 interventions packages commonly used with children with ASD. Participants: (1) indicated each treatment strategy and intervention package they use, and (2) rated the perceived evidence and value of each treatment strategy and intervention package they endorsed using. Results demonstrated that a variety of treatment strategies and intervention packages, both with and without an established evidence base, were reportedly being delivered to youth with ASD through community-based agencies. Additionally, a large number of providers reported not knowing the evidence of many treatment strategies and intervention packages. Finally, although no relationship was found between evidence base and use, perceived evidence, and value for treatment strategies, providers reported significantly higher use, perceived evidence, and value for established intervention packages. Results demonstrate the need to more effectively disseminate strategies that can support providers in selecting services to deliver to youth with ASD, and underscore the need to better understand the community service landscape on a larger scale.

My Turn is software used to manage several Covid-19 mass vaccination campaigns in California. The objective of this article is to describe the use of My Turn at two points of dispensing in California and comment on process improvements to reduce manual tasks of six identified processes of vaccination–registration, scheduling, administration, documentation, follow-up, and digital vaccine record–and paper. We reviewed publicly available documents of My Turn and patients vaccinated at George R. Moscone Convention Center in San Francisco and Oakland Coliseum Community Vaccination Clinic. For publicly available documents of My Turn, we examined videos of My Turn on YouTube, and documentation from EZIZ, the website for the California Vaccines for Children Program. For patients, we examined publicly available vaccination record cards on Instagram and Google. At the George R. Moscone Convention Center, 329,608 vaccines doses were given. At the Oakland Coliseum Community Vaccination Clinic, more than 500,000 vaccine doses were administered. The use of My Turn can be used to reduce manual tasks and paper for mass vaccinating patients against Covid-19. [ABSTRACT FROM AUTHOR]

Archives are not straightforward repositories of history. Instead, they authorize which stories are remembered. In this article we apply the insights of cultural geographers and other influential scholars of archives to analyze the political dimensions of archiving activist histories. A small group of antiprison activists produced a personal archive during the 1990s and 2000s documenting brutality behind bars and efforts to dismantle solitary confinement in California prisons. After being deemed too dangerous to be opened to the public by university archivists, and without a permanent home, the papers were at risk of being lost to history. By presenting our work building this archive, we analyze the limitations of institutional libraries and the vital role played by individuals and independent institutions willing to preserve dangerous papers, and we show how preserving histories of state violence and opposition can become a deeply personal and risky endeavor.

Mission statements have become increasingly important for the accreditation of business universities and colleges. Thus, understanding similarities and differences in the content of business school mission statements is especially timely. The mission statement is also the first component of the strategic management process. It provides the framework or context within which strategies are formulated. This descriptive/informative study aims to present a background that describes and explains institutional mission statements and removes the so-called uncertainty encompassing the foci while preserving exceptional quality--a necessary quality for a compelling mission statement. We question whether all California State University (CSU) and The State University of New York (SUNY) business colleges/schools have developed enduring and inspiring mission statements for their employees and students? While no specific rule regarding length exists, we examined the word count length of these two school system mission statements. Institutions must not make their mission statements too long or too short, or they will risk losing focus and missing essential elements to guide their organization. The mission statement must be long enough to achieve its purpose. Based on our findings, we recommend that all CSU and SUNY campuses embrace a more straightforward, easy-to-understand, hard-hitting, lasting, and inspirational mission statement for their business colleges/schools, one directly relevant to faculty, staff, students, and their families.

Ignition of waste paper sludge at elevated temperatures to produce electricity in power generation plants utilizing fluidized bed combustion generates paper sludge ash. Due to the high concentration of lime and gelignite in paper sludge ash, it is expected that it will play a vital role as a cementitious material. This paper investigates the use of paper sludge ash to improve the mechanical properties of the granular materials, which are suitable to subbase course for road and building constructions. Also, a comparison study with the use of Portland cement as an additive to granular materials has been covered. The mechanical properties were evaluated by conducting the California bearing ratio test for the two adopted methods. Moreover, the compressive strength of the samples using paper sludge ash and cement are investigated. In accordance to the California bearing ratio test, 4% paper sludge ash was indicated as the optimum ash content at which the California bearing ratio value increased by 173% and 111% in comparison with untreated material and 6% cement, respectively. On the other hand, and by means of the compressive strength, the granular materials with 4% paper sludge ash has compressive strength higher than those with 6% cement. [ABSTRACT FROM AUTHOR]

The migration literature contends that, unlike other immigrants, refugees resettled in the US benefit from a federal program of integration. These claims do not consider the barriers that may complicate the implementation of resettlement policy. Based on 16 months of ethnographic fieldwork at a refugee resettlement agency in California, I argue that the organizational structure of the US Resettlement Program shapes how caseworkers provide resettlement services on a daily basis. The financial insecurity of Resettlement Agencies coupled with high stakes government oversight creates an organizational culture of vulnerability where caseworkers rely on discretion as they put resettlement policy into practice. Caseworkers develop coping mechanisms to get by as they simultaneously attend to the demands of their funders and their refugee clients. Given these structural constraints and limited resources, caseworkers instrumentalize paperwork as a discretionary tool. When files and documents are privileged over the quality and extent of resettlement services, caseworkers creatively utilize paperwork to separate policy from practice in order to protect themselves and appease their refugee clients. This policy of integration instead becomes a practice of paper integration , which problematizes prior theories and assumptions about US refugee resettlement. This practice of paper integration ultimately affects the services that arriving refugees receive and the degree to which they benefit from this ostensible program of integration.

Objective: The association between higher registered nurses (RN) staffing (educational level and number) and better patient and nurse outcomes is well-documented. This discussion paper aims to provide an overview of safe staffing policies in various high-income countries to identify reform trends in response to recurring nurse workforce challenges., Methods: Based on a scan of the literature five cases were selected: England (UK), Ireland, California (USA), Victoria and Queensland (Australia). Information was gathered via a review of the grey and peer-reviewed literature. Country experts were consulted for additional information and to review country reports., Results: The focus of safe staffing policies varies: increasing transparency about staffing decisions (England), matching actual and required staffing levels based on patient acuity measurement (Ireland), mandated patient-to-nurse ratios at the level of the nurse (California) or the ward (Victoria, Queensland). Calibration of the number of patients by the number of nurses varies across cases. Nevertheless, positive effects on the nursing workforce (increased bedside staffing) and staff well-being (increased job satisfaction) have been consistently documented. The impact on patient outcomes is promising but less well evidenced., Conclusion: Countries will have to set safe staffing policies to tackle challenges such as the ageing population and workforce shortages. Various approaches may prove effective, but need to be accompanied by a comprehensive policy that enhances bedside nurse staffing in an evidence-based, objective and transparent way., Competing Interests: Declaration of Competing Interest The authors report no declarations of interest., (Copyright © 2020 Elsevier B.V.

The aim of this work was to fill the gap in California pest management by evaluating coverage and spatial uniformity of spray rig designs used in California strawberry production. Coverage can be improved up to 30% if the important design parameters are identified, which would reduce pests. Field evaluations were conducted in beds with 4 canopy lines in Santa Maria, CA on 162 cm beds and in Oxnard, CA on 172 cm beds as well as in beds with 2 canopy lines in Watsonville, CA on 122 cm beds and 132 cm beds. Water-sensitive paper cards placed adaxial and abaxial, both horizontally and vertically on plant canopies located near the middle and edge of the bed were used as the evaluation criteria. Data were analyzed by regression. Results from spray evaluations (n = 21) included recording the nozzle used, manifold height, number of nozzles per bed, volume sprayed, nozzle pressure, and tractor speed, as well as determining the percent coverage from 1,568 water-sensitive spray cards. Increasing nozzle pressure can potentially increase coverage by 9.18%. Positioning the nozzle closer to the canopy level can also significantly increase coverage. [ABSTRACT FROM AUTHOR]

Introduction: Fresno, California, is home to more than 30,000 Hmong. The purpose of this research was to explore the utilization of Hmong shamans 40 years after the first Hmong immigrants arrived in the United States. Hmong shamanism is examined to identify and analyze changes to shamans' practices or patients., Methods: Using grounded theory, semistructured interviews were conducted with a convenience sample of 20 shamans in their homes. Transcribed data were qualitatively analyzed., Results: Shamans continue to train and practice in this community; utilization by older patients persists while young adult patients have become the fastest-growing group of users. Healing rituals have changed in response to the legalities of animal sacrifice in urban areas and the time demands of work schedules., Discussion: Nurses' awareness that the availability of biomedicine does not preclude the continuing or recurring utilization of traditional healers can facilitate understanding of culturally defined health care needs.

This paper focuses on the sacred text-production work of a Nyingma Buddhist group based in Berkeley, California. It unpacks their selective engagement with the tools afforded to them by digitisation and new media. Digitisation projects – appearing in growing numbers – offer a powerful resource for the re-assembly of Tibetan Buddhist textual collections scattered in the political upheaval of recent decades. Yet the meeting place between the digital and the sacred is sometimes contested in this context where sacred text is an embodiment of the Buddha's speech. This paper argues that the choice to print ink-and-paper texts is more than a simple rehearsal of tradition and in fact demands alternative forms of engagement with the potential offered by media tools. It explores how the moral invectives contained within sacred Tibetan texts become reshaped through the prisms of contemporary media and the American sponsorship landscape. [ABSTRACT FROM AUTHOR]

The archetype of the self underlies the ego-complex at its root and source in the unconscious. None of these assigns to the self the role that I feel to be so essential in the syndrome. SP 50-52 sp In regard to the method of study of these processes of the archaic, unconscious psyche in psychosis, I find myself baffled as to how to set up anything like a scientific approach to the material. In this hypothesis the model is easy to visualize but difficult to understand in terms of experience; the self is seen in this case as the center of the total psychic organism, and the ego is subsumed within this totality as the center of the field of consciousness only, that is, of contents accessible to consciousness; between the two are the autonomous complexes, which are groupings of contents not accessible to ego-consciousness (Figure 1). Reconstitutive process in the psychopathology of the self1: The following paper by J.W. Perry is published with permission from the Annals of the New York Academy of the Sciences where it was first published in January 1962. The imagery I refer to is a whole class of symbolic representations of centrality and organization, of order and highest authority; I hope to demonstrate that in these we see representations of the self and processes that transform or reorganize the self in the unconscious psyche.

Background and Context: Continuous improvement and networked improvement science have emerged as prominent approaches to improving schools. Although continuous improvement approaches have generated promising results in education, how these efforts come to be enacted remains a crucial question that can generate insight into how these approaches can be improved. Purpose and Objective: Our study is focused on understanding how improvement is performed by focusing on the process of generating a shared aim statement in a teacher-preparation improvement network. We seek to understand how practitioners within a network (a) engage a central tension (between language acquisition and multilingualism), (b) negotiate this tension, and (c) reach a settlement that results in a shared aim. Setting: This study takes place in a teacher-preparation improvement network as part of the California Teacher Education Research and Improvement Network (CTERIN). The focus of the network centered on improving the preparation of candidates to build on multilingual students' strengths. Participants: The improvement network that is the focus of our research consists of 49 teacher educators across eight teacher preparation programs as well as three facilitators who were part of CTERIN, including the two authors of this study. Research Design: Our analysis examines the interactions among teacher educators and improvement facilitators to unveil the practices that they engaged in to produce a shared aim. Data for this study include audio and video recordings of three 90-minute videoconference meetings, audio-video of a two-day in-person convening, and improvement artifacts such as fishbone and driver diagrams. Findings: Our study highlights the range of practices that practitioners engaged in and how those evolved as they negotiated and settled a tension between language acquisition and multilingualism. As the process of generating an aim unfolded, teacher educators engaged in the practices of aspirationalizing, dualizing, recentering, rerouting, clarifying, tuning, and converting. Conclusions and Recommendations: We argue that these practices make visible that the process of generating an aim statement is a complex and complicated process that requires negotiation and a recognition that some perspectives are foregrounded and others are backgrounded. Understanding this process has implications for how improvement facilitators engage practitioners in the process of doing improvement and generates theory of improvement implementation by highlighting how disparate teams, individuals, and organizations reaching sharedness requires negotiating, foregrounding, and backgrounding.

As improving equity becomes prioritized in higher education, Offices of Institutional Research (OIRs) find themselves in a central position to identify and address educational inequities faced by racially minoritized students. However, their potential to serve as a catalyst for organizational change has yet to be fulfilled. In this study, we present a critical discourse analysis of mission statements to understand how these OIRs describe their function and purpose in the California Community Colleges system. Results are based on 108 reviewed statements. These results reveal a limited discourse around race and equity. None of the statements in our sample included the word race or any words stemming from it such as racism or racial disparity. The majority (86%) of statements omitted equity from their purpose, failing to describe how OIRs can serve to improve equitable outcomes in community college. Our work prompts the field to reimagine their role within the community college they serve by becoming race-conscious and equity-minded in the ways they articulate their role and function as major hubs of institutional data.

Objective Healthcare and mortality costs of secondhand smoke (SHS) exposure at home among nonsmokers in California were estimated for the year 2009. Methods Costs were estimated with an epidemiological model using California SHS home exposure rates and published relative risks. Healthcare costs included nine conditions, and mortality was estimated for four perinatal and three adult conditions. Three mortality-related measures were estimated: deaths, years of potential life lost (YPLL) and the value of lost productivity. Results SHS-attributable healthcare costs totalled over $241 million. The most costly conditions for children and adolescents were attention deficit hyperactivity disorder ($7.8 million) and middle ear disease ($5.6 million). For adults, the most costly conditions were ischaemic heart disease (IHD) ($130.0 million) and asthma ($67.4 million). Deaths of 821 Californians were attributable to SHS exposure in the home, including 27 infants whose mothers smoked while pregnant and 700 adults who died from IHD. These deaths represented a loss of over 13 000 YPLL and $119 million in lost productivity. Conclusions The economic impact of SHS exposure in the home totalled $360 million in California in 2009. Policies that reduce exposure to SHS at home have great potential for reducing healthcare and mortality costs. [ABSTRACT FROM AUTHOR]

Objectives Exposure of adults to secondhand smoke (SHS) has immediate adverse effects on the cardiovascular system and causes coronary heart disease. The current study evaluated brief self-report screening measures for accurately identifying adult cardiology patients with clinically significant levels of SHS exposure in need of intervention. Design and setting A cross-sectional study conducted in a university-affiliated cardiology clinic and cardiology inpatient service. Patients Participants were 118 non-smoking patients (59% male, mean age=63.6 years, SD=16.8) seeking cardiology services. Main outcome measures Serum cotinine levels and self-reported SHS exposure in the past 24 h and 7 days on 13 adult secondhand exposure to smoke (ASHES) items. Results A single item assessment of SHS exposure in one’s own home in the past 7 days was significantly correlated with serum cotinine levels (r=0.41, p<0.001) with sensitivity ≥75%, specificity >85% and correct classification rates >85% at cotinine cut-off points of >0.215 and >0.80 ng/mL. The item outperformed multiitem scales, an assessment of home smoking rules, and SHS exposure assessed in other residential areas, automobiles and public settings. The sample was less accurate at self-reporting lower levels of SHS exposure (cotinine 0.05-0.215 ng/mL). Conclusions The single item ASHES-7d Home screener is brief, assesses recent SHS exposure over a week's time, and yielded the optimal balance of sensitivity and specificity. The current findings support use of the ASHES- 7d Home screener to detect SHS exposure and can be easily incorporated into assessment of other major vital signs in cardiology. [ABSTRACT FROM AUTHOR]

There has been vigorous debate within the state of California and elsewhere as to what constitutes appropriate procedures for determining whether an individual qualifies for special education and related services under the category of specific learning disability (SLD). Within the professional literature, there is growing support for educational agencies to adopt an approach to SLD identification that emphasizes the importance of an individual's pattern of cognitive and achievement strengths and weaknesses (PSW). In 2014, the California Association of School Psychologists released a position paper endorsing this approach. As a vehicle for examining the PSW model, we respond critically to three fundamental positions taken in the position paper: (a) diagnostic validity for the model has been established; (b) cognitive profile analysis is valid and reliable; and (c) PSW data have adequate treatment utility. We conclude that at the present time there is insufficient support within the empirical literature to support adoption of the PSW method for SLD identification. Implications for professional practice are discussed.

The California Association of School Psychologists (CASP) responds to a critique of the Association's Position Paper: "Specific Learning Disabilities and Patterns of Strengths and Weaknesses" (2014, March. Available: http://casponline.org/about-casp/publications/) by McGill and Busse. The CASP offers corrections to McGill and Busse's three critiques and clarifies the Association position that the assessment of students suspected of having a Specific Learning Disability involves a comprehensive evaluation that provides information regarding both environmental factors that include data on instruction and interventions as well as within-child factors such as response to intervention and the student's pattern of academic and specific cognitive strengths and weaknesses.

The article discusses a meeting with theme ‘‘Making Sound Waves'' of the National Hearing Conservation Association (NHCA) that was held in San Diego, California. Topics discussed include improve the success of Hearing Loss Prevention Programmes for preventing the progression of noise-induced hearing loss (NIHL), use of personal protective equipment (PPE) in the form of hearing protection devices (HPDs) such as ear plugs, and predicting noise exposures across workers in the mining industry.

This paper presents an overview of the process of entanglement at the 25th International Philosophy of Nursing Conference (IPNC) at University of California at Irvine held on August 18, 2022. Representing collective work from the US, Canada, UK and Germany, our panel entitled 'What can critical posthuman philosophies do for nursing?' examined critical posthumanism and its operations and potential in nursing. Critical posthumanism offers an antifascist, feminist, material, affective, and ecologically entangled approach to nursing and healthcare. Rather than focusing on the arguments of each of the three distinct but interrelated panel presentation pieces, this paper instead focuses on process and performance (per/formance) and performativity as relational, connected and situated, with connections to nursing philosophy. Building upon critical feminist and new materialist philosophies, we describe intra‐activity and performativity as ways to dehierarchise knowledge making practices within traditional academic conference spaces. Creating critical cartographies of thinking and being are actions of possibility for building more just and equitable futures for nursing, nurses, and those they accompany—including all humans, nonhumans, and more than human matter.

A version of this paper was given as the Inaugural Steven Edwards Memorial Lecture at the 25th conference of the International Philosophy of Nursing Society 16th August 2022. Using the literary meaning of 'whither', that is 'to what place', this paper will explore the role of philosophy in nursing, past, present, and future. The paper will begin with some thoughts on the history of nursing philosophy, its development as a subject and the scholarly activities that have led to where it sits today. The establishment of the journal Nursing Philosophy, the Annual Nursing Philosophy Conference, the International Philosophy of Nursing Society (IPONS) and their influence on nursing both in the academy and in practice will be discussed. The concept of nursing philosophy as a discipline will be considered, and how this fits with nursing theory, and nursing knowledge. Philosophical questions central to understanding contemporary nursing in a globalised world will be explored and the use of analytical philosophy and philosophical method in addressing such questions. The paper will conclude by looking to the future; what the role of philosophy might be in shaping nursing as a discipline and in the preparation of future practitioners. [ABSTRACT FROM AUTHOR]

Earthquake nowcasting has been proposed as a means of tracking the change in large earthquake potential in a seismically active area. The method was developed using observable seismic data, in which probabilities of future large earthquakes can be computed using Receiver Operating Characteristic methods. Furthermore, analysis of the Shannon information content of the earthquake catalogs has been used to show that there is information contained in the catalogs, and that it can vary in time. So an important question remains, where does the information originate? In this paper, we examine this question using stochastic simulations of earthquake catalogs. Our catalog simulations are computed using an Earthquake Rescaled Aftershock Seismicity ("ERAS") stochastic model. This model is similar in many ways to other stochastic seismicity simulations, but has the advantage that the model has only 2 free parameters to be set, one for the aftershock (Omori‐Utsu) time decay, and one for the aftershock spatial migration away from the epicenter. Generating a simulation catalog and fitting the two parameters to the observed catalog such as California takes only a few minutes of wall clock time. While clustering can arise from random, Poisson statistics, we show that significant information in the simulation catalogs arises from the "non‐Poisson" power‐law aftershock clustering, implying that the practice of de‐clustering observed catalogs may remove information that would otherwise be useful in forecasting and nowcasting. We also show that the nowcasting method provides similar results with the ERAS model as it does with observed seismicity. Plain Language Summary: Earthquake nowcasting was proposed as a means of tracking the change in the potential for large earthquakes in a seismically active area, using the record of small earthquakes. The method was developed using observed seismic data, in which probabilities of future large earthquakes can be computed using machine learning methods that were originally developed with the advent of radar in the 1940s. These methods are now being used in the development of machine learning and artificial intelligence models in a variety of applications. In recent times, methods to simulate earthquakes using the observed statistical laws of earthquake seismicity have been developed. One of the advantages of these stochastic models is that it can be used to analyze the various assumptions that are inherent in the analysis of seismic catalogs of earthquakes. In this paper, we analyze the importance of the space‐time clustering that is often observed in earthquake seismicity. We find that the clustering is the origin of information that makes the earthquake nowcasting methods possible. We also find that a common practice of "aftershock de‐clustering", often used in the analysis of these catalogs, removes information about future large earthquakes. Key Points: Earthquake nowcasting tracks the change in the potential for large earthquakes, using information contained in seismic catalogsWe analyze the information contained in the space‐time clustering that is observed in earthquake seismicityWe find that "aftershock de‐clustering" of catalogs removes information about future large earthquakes that the nowcasting method uses [ABSTRACT FROM AUTHOR]

Timely evaluation and reperfusion have improved the myocardial salvage and the subsequent recovery rate of the patients hospitalized with acute myocardial infarction (MI). Long waiting time and time-consuming procedures of in-hospital diagnostic testing severely affect the timeliness. We present a Poincare pattern ensemble-based method with the consideration of multi-correlated non-stationary stochastic system dynamics to localize the infarct-related artery (IRA) in acute MI by fully harnessing information from paper-based Electrocardiogram (ECG). The vectorcardiogram (VCG) diagnostic features extracted from only 2.5-s long paper ECG recordings were used to hierarchically localize the IRA—not mere localization of the infarcted cardiac tissues—in acute MI. Paper ECG records and angiograms of 106 acute MI patients collected at the Heart Artery and Vein Center at Fresno California and the 12-lead ECG signals from the Physionet PTB online database were employed to validate the proposed approach. We reported the overall accuracies of 97.41% for healthy control (HC) vs. MI, 89.41 ± 9.89 for left and right culprit arteries vs. others, 88.2 ± 11.6 for left main arteries vs. right-coronary-ascending (RCA) and 93.67 ± 4.89 for left-anterior-descending (LAD) vs. left-circumflex (LCX). The IRA localization from paper ECG can be used to timely triage the patients with acute coronary syndromes to the percutaneous coronary intervention facilities. [ABSTRACT FROM AUTHOR]

Hydraulic jacking is a serious threat to concrete spillway chutes, demonstrated by the catastrophic spillway chute failure at California's Oroville Dam in 2017. To improve the understanding of uplift pressure and joint flow developed at open, offset joints and enable design and evaluation of anchors, drain systems, and joint remediations that could help prevent such failures, laboratory tests were performed in a supercritical flume furnished with a model joint where the gap width to offset height ratio was varied over a 725∶1 range. The tests included measurement of boundary layer velocity profiles approaching the joint. Uplift pressures were normalized to the velocity head near the boundary, which is related to the depth-wise velocity profile exponents determined in the experiments and can be estimated for field applications from the chute friction factor. The normalized uplift varies with the joint aspect ratio and the flow depth to offset height ratio. The new relations reduce the uncertainty of modeled uplift pressures by a factor of 2.87 over previous methods. Example applications demonstrate practical upper limits for potential uplift pressure. Subsequent articles will address discharge into offset joints, the dissipation of uplift via drainage, and the effect of different methods for remediating existing offsets to reduce uplift. Practical Applications: Concrete spillway chutes develop cracks and must necessarily be constructed with joints, both of which are prone to displacement over time that may create offsets into the flow. Flow striking such offsets is brought suddenly to rest, similar to a pedestrian tripping on a sidewalk crack. The local stoppage of flow at the offset creates dangerously high pressures that can be injected into the foundation, leading to erosion beneath the slab and potential uplift failure, often called 'hydraulic jacking'. This mechanism has caused several notable failures including the Oroville Dam spillway in 2017. Protection against such failures is usually provided by a combination of the weight (thickness) of the slab itself, anchors that hold the slab down, and subsurface drains that reduce the buildup of pressure. This paper provides experimentally based equations for predicting uplift pressure to enable effective design of new spillways and evaluation of existing spillways. The new equations are significantly more accurate than previous methods because they account for the roughness of the chute surface and the reduced flow velocity near the boundary. Subsequent papers will address flow rate through joints, pressure dissipation by drainage, and methods for treating existing offsets to reduce potential uplift. [ABSTRACT FROM AUTHOR]

Planning for future ocean conditions requires historical data to establish more informed ecological baselines. To date, this process has been largely limited to instrument records and observations that begin around 1950. Here, we show how marine macroalgae specimens from herbaria repositories may document long-term ecosystem processes and extend historical information records into the nineteenth century. We tested the effect of drying and pressing six macroalgae species on amino acid, heavy metal and bulk stable isotope values over 1 year using modern and archived paper. We found historical paper composition did not consistently affect values. Certain species, however, had higher variability in particular metrics while others were more consistent. Multiple herbaria provided Gelidium (Rhodophyta) samples collected in southern Monterey Bay from 1878 to 2018. We examined environmental relationships and found δ15N correlated with the Bakun upwelling index, the productivity regime of this ecosystem, from 1946 to 2018. Then, we hindcasted the Bakun index using its derived relationship with Gelidium δ15N from 1878 to 1945. This hindcast provided new information, observing an upwelling decrease mid-century leading up to the well-known sardine fishery crash. Our case study suggests marine macroalgae from herbaria are an underused resource of the marine environment that precedes modern scientific data streams. [ABSTRACT FROM AUTHOR]
