Graphical abstract Highlights • Technology cost and utility rate structure are key drivers of economic viability of solar and storage systems. • Solar-plus-storage systems are more often economical under time of use and demand charge rates. • Savings from storage-only projects come mainly from demand charge reductions; solar combined with storage also provides energy charge savings. • Savings from solar with storage is largely independent of building load variability, likely due to the energy cost reductions from the solar. Abstract This paper explores the economics of solar-plus-storage projects for commercial-scale, behind-the-meter applications. It provides insight into the near-term and future solar-plus-storage market opportunities across the U.S. We explore the impacts of location, building load profile, technology cost, utility rate structure, and policies on solar-plus-storage economic viability, and identify which factors are most significant to project economics. While savings from storage-only projects are largely derived from demand charge reductions, solar combined with storage also provides significant energy charge savings. A common assumption is that load profiles with peaks are likely candidates for savings from storage, due to the opportunity for demand charge reduction. Our results indicate that potential for savings from combining solar with storage is independent of building load variability, likely due to the energy cost reductions from the solar. Systems are more often economical under time of use and demand charge rates, particularly when demand charges are >$10 per kilowatt. Where systems were found to be economical, expected lifetime savings averaged between 7%–10%, with savings of 30% in numerous cases. Near term markets exist for solar-plus-storage in locations such as California and New York. As technology prices drop, the number of building types that can benefit increase, and additional markets appear in Colorado, New Mexico, and Alaska.

Recently, the US has dramatically expanded immigration enforcement. At the same time, some advocates have sought to support “good” immigrants. This paper considers how the resulting good/bad binaries affect undocumented immigrants. I examine a case study in Los Angeles, where policing intertwined with protection. Based on participant observation and interviews, I show that respondents believed state agents classified them either as “bad” criminals or “good”, immigrants. To the extent immigrants identified as “good”, they credited the US with offering them “freedom” and hoped for political inclusion. At the same time, in what I call moralizing regulation, they also performed “good” behaviour and distinguished themselves from those seen as “bad”. Some also tied “good” behaviour to femininity and “acting white”. At the extreme, they blamed other migrants for inviting state mistreatment. The effects were ambivalent: while immigrants appreciated US support, they also adopted and adapted to the state’s moral norms. [ABSTRACT FROM AUTHOR]

This paper describes the role of televised sports in married life. It documents how adults integrate televised sports into their relationship with their spouse and evaluate its impact on that relationship. Telephone interviews were conducted with 399 married adults residing in San Francisco and Indianapolis. Respondents were asked about their own TV sports viewing behaviors as well as those of their spouse. Televised sports appears to play a generally positive albeit small role in marital life. TV sports viewing often is a shared activity and does not appear to trigger many scheduling or TV viewing conflicts. And, when such conflicts occurs, they appear to be resolved amicably and easily. It may be that accommodations for differing interests in TV sports are resolved early in a marital relationship, along with other accommodations that marriage often dictates. [ABSTRACT FROM AUTHOR]

Heroin overdose, more accurately termed ‘heroin-related overdose’ due to the frequent involvement of other drugs, is the leading cause of mortality among regular heroin users. (Degenhardt et al., 2010) Heroin injectors are at greater risk of hospital admission for heroin-related overdose (HOD) in the eastern United States where Colombian-sourced powder heroin is sold than in the western US where black ‘tar’ heroin predominates. (Unick et al., 2014) This paper examines under-researched influences on HOD, both fatal and non-fatal, using data from a qualitative study of injecting drug users of black tar heroin in San Francisco and powder heroin in Philadelphia Data were collected through in-depth, semi-structured interviews carried out in 2012 that were conducted against a background of longer-term participant-observation, ethnographic studies of drug users and dealers in Philadelphia (2007–12) and of users in San Francisco (1994–2007, 2012). Our findings suggest three types of previously unconsidered influences on overdose risk that arise both from structural socio-economic factors and from the physical properties of the heroin source-types: 1) retail market structure including information flow between users; 2) marketing techniques such as branding, free samples and pricing and 3) differences in the physical characteristics of the two major heroin source forms and how they affect injecting techniques and vascular health. Although chosen for their contrasting source-forms, we found that the two cities have contrasting dominant models of drug retailing: San Francisco respondents tended to buy through private dealers and Philadelphia respondents frequented an open-air street market where heroin is branded and free samples are distributed, although each city included both types of drug sales. These market structures and marketing techniques shape the availability of information regarding heroin potency and its dissemination among users who tend to seek out the strongest heroin available on a given day. The physical characteristics of these two source-types, the way they are prepared for injecting and their effects on vein health also differ markedly. The purpose of this paper is to examine some of the unexplored factors that may lead to heroin-related overdose in the United States and to generate hypotheses for further study.

The aim of this paper is to present the initial results of a study on Maya-Yucatecan migrant women who have settled permanently in Los Angeles, California. The reasons that led them to migrate are addressed as well as the way they came to the United States and joined the work force. Certain aspects that permitted their insertion into Los Angeles society are highlighted, together with identity recovery practices to show that adaptation to the host culture is slow, irregular and incomplete, but enough for them to deploy survival strategies. The paper is based on the assumption that female migration lends this phenomenon specific characteristic that warrant special attention. Accordingly, the analysis of the document is based on an interpretation of the meaning of the actions, for which the content of ten in-depth interviews conducted in Los Angeles in 2012 was used.

This paper explores the way in which psychologists classified immigrant children as feebleminded through the use of intelligence testing and how state organisations consequently segregated them from public schools based on the scientific evidence. First, I show the way in which the psychologist Lewis Terman utilised intelligence testing to identify immigrant children deemed feebleminded. I focus closely on a survey and on his methodology and analysis. I then discuss the possibilities of education for the feebleminded and the segregation of immigrant children from regular classroom of public schools. Through his survey, Terman concluded that the exceptionally high ratio of feebleminded children in the tested region was caused by the large population of immigrant children, although the selection of the sample was often subjective, leading to “miscalculation” in his analysis. Terman’s survey was influential in terms of segregating feebleminded children by stating their incurability; possibilities of education for the feebleminded were thus denied. At his suggestion, special classes and schools, along with a home for the feebleminded, were established. Terman’s psychological survey was a cue for psychologists to enter the school system. The State Board of Education was not only attempting to discover the percentage of feebleminded children but also trying to apply psychology to school training. With the cooperation of the Board, the training of teachers for the feebleminded proceeded. [ABSTRACT FROM PUBLISHER]

Introduction Collabo RATE is a brief patient survey focused on shared decision making. This paper aims to (i) provide insight on facilitators and challenges to implementing a real-time patient survey and (ii) evaluate Collabo RATE scores and response rates across multiple clinical settings with varied patient populations. Method All adult patients at three United States primary care practices were eligible to complete Collabo RATE post-visit. To inform key learnings, we aggregated all mentions of unanticipated decisions, problems and administration errors from field notes and email communications. Mixed-effects logistic regression evaluated the impact of site, clinician, patient age and patient gender on the Collabo RATE score. Results While Collabo RATE score increased only slightly with increasing patient age ( OR 1.018, 95% CI 1.014-1.021), female patient gender was associated with significantly higher Collabo RATE scores ( OR 1.224, 95% CI 1.073-1.397). Clinician also predicts Collabo RATE score (random effect variance 0.146). Site-specific factors such as clinical workflow and checkout procedures play a key role in successful in-clinic implementation and are significantly related to Collabo RATE scores, with Site 3 scoring significantly higher than Site 1 ( OR 1.759, 95% CI 1.216 to 2.545) or Site 2 (z=−2.71, 95% CI −1.114 to −0.178). Discussion This study demonstrates that Collabo RATE can be used in diverse primary care settings. A clinic's workflow plays a crucial role in implementation. Patient experience measurement risks becoming a burden to both patients and administrators. Episodic use of short measurement tools could reduce this burden. [ABSTRACT FROM AUTHOR]

Concern is growing in the United States regarding the potential for health insurance benefit designs to discriminate against persons living with HIV as research demonstrates that such practices are occurring. A recent complaint filed against health insurers in seven states alleges that some health insurance companies have been using benefit designs that discourage enrollment of people living with HIV either by not covering essential HIV medications or by requiring cost-sharing for these prohibitively expensive medications. Legislators across the country have reacted by introducing legislation to address these growing problems. This paper describes Assembly Bill 339, legislation passed in California in 2015 and going into effect on 1 January 2017, which provides protection for people living with HIV by requiring coverage for single-tablet regimens to manage HIV while placing a cap on patient cost-sharing. Given California’s size and influence, and the uncertainty of the future of the Affordable Care Act, this legislation has the potential to influence the national policy debate.

Purpose Worldwide efforts to identify individuals infected with the hepatitis C virus (HCV) focus almost exclusively on community healthcare systems, thereby failing to reach high-risk populations and those with poor access to primary care. In the USA, community-based HCV testing policies and guidelines overlook correctional facilities, where HCV rates are believed to be as high as 40 percent. This is a missed opportunity: more than ten million Americans move through correctional facilities each year. Herein, the purpose of this paper is to examine HCV testing practices in the US correctional system, California and describe how universal opt-out HCV testing could expand early HCV detection, improve public health in correctional facilities and communities, and prove cost-effective over time. Design/methodology/approach A commentary on the value of standardizing screening programs across facilities by mandating all facilities (universal) to implement opt-out testing policies for all prisoners upon entry to the correctional facilities. Findings Current variability in facility-level testing programs results in inconsistent testing levels across correctional facilities, and therefore makes estimating the actual number of HCV-infected adults in the USA difficult. The authors argue that universal opt-out testing policies ensure earlier diagnosis of HCV among a population most affected by the disease and is more cost-effective than selective testing policies. Originality/value The commentary explores the current limitations of selective testing policies in correctional systems and provides recommendations and implications for public health and correctional organizations.

This paper asks what a “cultural turn” in transportation geography might look like. In taking seriously Susan Hanson's claim that transportation geography has become a “moribund corner” of the discipline, this paper suggests a set of new avenues for inquiry. To do so, the paper draws on fieldwork I conducted in California's East Bay, as well as the story a fictitious transit system called the “B-Line.” Despite being a fiction, I argue that the B-Line offers an excellent entry point into mapping what a “cultural turn” in transportation geography might entail. Speaking to the larger theme of “doing cultural geography,” this essay argues that doing cultural geography not only means continuing to explore questions of representation, ideology, and cultural meaning, but it also means applying those questions to areas of study like transportation geography—areas where such questions remain largely unexplored.

Scholars typically study affluent neighbourhoods resisting annexation by poorer adjacent cities. This paper focuses on the mirror image of this problem: municipal underbounding—the unwillingness of cities to annex poor neighbouring areas. In the paper, such local governments are called reluctant cities and it is suggested that urban studies scholars need to reach a better understanding of the practice. Here, a seemingly counter-intuitive case from California is documented where adjacent cities were convinced to annex poor neighbourhoods, designated as colonias. It is suggested that there may be opportunities for local co-operation leading to annexation. The important role of federal infrastructure funding is noted and the need for deeper involvement of residents of annexed neighbourhoods in decision-making is emphasised. Although race was not an issue in this case study, it is likely to be an important concern in annexations and the literature’s call for regional approaches and institutional reforms is supported.

For Salvadorans who relocated to the United States, the marginalization imposed by American society, the victimization enacted by Mexican gangs and their negative experience with El Salvador's practice of citizenship brought them to create the Mara Salvatrucha (MS-13) and modify 18th Street gangs in the neighborhoods of Los Angeles. Living on the fringes of society, they were kept from attaining the social, civil and economic benefits of a liberal democratic model of citizenship. This paper claims that, in order to survive, they took it upon themselves to create a parallel model of citizenship, combining anarchism with ''citizenship as agency'' under the gang structure. Following Philip Oxhorn's analysis of models of citizenship, this study examines how Salvadoran refugees came to create such alternative citizenship in the framework of the MS-13 and 18th Street gangs. Analysis asserts that the structure and development of membership in the gangs is not a coincidence, but rather a response to their marginalization, negative experience of state citizenship, and their participation in public arenas modeled as an extension of social contracts. Understanding the views of these, now transnational, gangs in terms of citizenship can aid policymakers and Central American governments as they approach these groups, eliminating violence and promoting development.

Background: Knowledge of patient characteristics, surgical fixation, graft choice, outcomes, and concurrent injuries of revision anterior cruciate ligament reconstruction (ACLR) is limited. Purpose: To describe the current cohort of revision ACLR captured by a community registry and the outcomes observed in the registered patients. Study Design: Case series; Level of evidence, 4. Methods: Patients who underwent revision ACLR registered between February 2005 and June 2014, by 200 surgeons in 46 hospitals, were evaluated. The Kaiser Permanente ACLR Registry (KPACLRR) collected data intraoperatively and postoperatively using paper forms, electronic medical records, administrative claims data, and patient-reported outcomes. The KPACLRR cohort was longitudinally followed, and outcomes were prospectively ascertained. Outcomes (ie, revisions, subsequent operative procedures, deep surgical site infections, and deep venous thrombosis) were adjudicated via a chart review. Descriptive statistics were employed. Results: Of 2019 patients who underwent revision ACLR, at a median follow-up of 2.2 years (interquartile range, 1.0-3.8 years), 212 (10.5%) required subsequent operative procedures, and 86 (4.3%) were revised a second time. At the time of revision, 55.1% of the patients had at least 1 concurrent meniscal injury, and 26% of those were repairable. Cartilage injuries were present in 42.0% of patients. Deep surgical site infections occurred in 12 patients (0.6%), deep venous thrombosis occurred in 5 patients (0.3%), and 1 patient (0.1%) had a pulmonary embolism. Conclusion: Revision ACLR can be performed with a low short-term revision rate and relatively few complications. At the time of revision, nearly half of these patients had an irreparable meniscal injury, and slightly less than half had a cartilage injury. A large community-based ACLR registry is useful in informing surgeons of current treatment practices, prevalence of concurrent injuries, and outcomes associated with the procedures, especially infrequent procedures such as revision ACLR.

In the first three decades of the twentieth century, the Los Angeles metropolitan area emerged as the fastest growing urban–industrial economy on the Pacific Coast. This was a significant achievement for a city without a natural harbour. Despite formidable barriers presented by physical geography, the gradual development of a deep-water harbour in Los Angeles was fundamental to the emergence of oil-based capitalism in Southern California. In the first three decades of the twentieth century, under the municipal governance of a Board of Harbor Commissioners, private oil companies developed Los Angeles Harbor into a modern transhipment facility comprising infrastructures and technologies dedicated to the efficient transportation, storage, and refining of petroleum and petroleum-based products. From this perspective, Los Angeles Harbor needs to be understood as a long-term, fixed-capital investment into oil-based energy as fuel for industry and transportation. As a transhipment facility, Los Angeles Harbor also functioned as a critical outlet for surplus energy after the discovery of several large fields in the Los Angeles Basin in the early 1920s. By focusing on a particular built landscape, this paper aims to contribute insight into how geographies of fixed-capital investment play a role in the regional dynamics of energy transition and establishment.

Purpose Despite the existence of minimum age laws for juvenile justice jurisdiction in 18 US states, California has no explicit law that protects children (i.e. youth less than 12 years old) from being processed in the juvenile justice system. In the absence of a minimum age law, California lags behind other states and international practice and standards. The paper aims to discuss these issues. Design/methodology/approach In this policy brief, academics across the University of California campuses examine current evidence, theory, and policy related to the minimum age of juvenile justice jurisdiction. Findings Existing evidence suggests that children lack the cognitive maturity to comprehend or benefit from formal juvenile justice processing, and diverting children from the system altogether is likely to be more beneficial for the child and for public safety. Research limitations/implications Based on current evidence and theory, the authors argue that minimum age legislation that protects children from contact with the juvenile justice system and treats them as children in need of services and support, rather than as delinquents or criminals, is an important policy goal for California and for other national and international jurisdictions lacking a minimum age law. Originality/value California has no law specifying a minimum age for juvenile justice jurisdiction, meaning that young children of any age can be processed in the juvenile justice system. This policy brief provides a rationale for a minimum age law in California and other states and jurisdictions without one. [ABSTRACT FROM AUTHOR]

This paper examines how race, class, and gender intersect to shape professional Latinos’ entrepreneurial incorporation, as observed by the conditions that prompt professional Latinos to start a business, including access to capital and experiences with discrimination. In-depth interviews with professional Latino business owners in Los Angeles reveal that individual human capital – via resources and wealth accrued through corporate careers – facilitates entrepreneurial activity. Race, ethnicity, and gender, as intersectional social group identities, combine with class to shape variegated impacts on access to capital and business experiences by gender and target market. Ethnicity is a resource for those serving the coethnic community and is more significant in shaping business ownership experiences for men who target a racially/ethnically diverse clientele, whereas gender and race are more salient for women outside the coethnic community. This study contributes to the ethnic enterprise literature by going beyond ethnicity to demonstrate that multiple dimensions of identity shape professional Latino/as’ entrepreneurial incorporation.

This paper argues that citizens are capable of developing and promoting complex policy symbols, and that these symbols include supporting frames that explain and justify them. Based on a long-term study of education policies in Los Angeles, California, the paper uses interpretive methods to reconstruct and analyze these frames. Citizens developed two specific policy symbols while the district was engulfed in a desegregation debate; citizens identified schools as places where students gained academic knowledge and as institutions that affected broader race relations. However, education policy in Los Angeles could not support these two symbols over a long period of time, and a political movement to end mandatory busing eventually caused the academic symbol (originally the weaker of the two symbols) to become dominant. This trend reflects broader national discussions, in which education is now discussed in terms of standards and accountability and is evidence of continuing racism in US policy.

Abstract: The performance of Calpine''s Geysers steam field from startup in 1960 to 2008 is described in this paper. Since October 2003, Calpine has received approximately 482L/s of tertiary-treated reclaimed water from the City of Santa Rosa. To accommodate and derive benefit from this water, Calpine has converted 20 wells (ten producers, six shut-in, two observation, and two suspended wells) to high-rate injection service. Additional nine wells were also converted to low-rate injectors that receive 12.6L/s or less. Annual recovery factors (i.e., fieldwide increase in annual steam production divided by annual injection) for the first 5 years of Santa Rosa Geysers Recharge Project (SRGRP) operation have been estimated at 17.6%, 26.1%, 37.1%, 39% and 44.6%, respectively; reasonably close to or slightly higher than the values, predicted prior to SRGRP startup. Using a revised definition that includes the amount of un-boiled water in the reservoir, the annual recovery factors turn out to be 17.6%, 16.1%, 14.6%, 12.4% and 12.2% from year one through year five. Improvements in the wellfield, water injection, and power plant modifications from January 1995 through December 2008 are also discussed in this paper. [Copyright &y& Elsevier]

Critics often mourn a loss of publicness in cities due to the increased presence of antiterror security zones and related behavioral and access controls, although recent work suggests that security landscapes have shifted from the hard, intense, militarized architecture of the late 1990s-early 2000s to a softer, less obtrusive approach more commonly seen today. Nonetheless, these studies are mostly anecdotal in nature: few studies attempt to back these claims with empirical evidence and even fewer connect this physical security imposition with the policies and plans governing its implementation and operation. In this paper I describe results of site visits to Civic Centers and Financial Districts in New York City, Los Angeles, and San Francisco. In each neighborhood I catalog security landscapes using a simple tool to assess the intensity, duration, and location of individual security zones. I find that the security landscape covers between 3.4% and 35.7% of publicly accessible space in the districts studied, and that this landscape is most prevalent and intense in New York City. I also find that security zones governed by multistakeholder networks are more intense and militarized than zones managed by a single entity. By understanding how the policies impact physical security, albeit in a relatively small sample of cities and districts, we can better predict what the future of urban security measures might hold. This paper provides empirical grounding to more common theoretical speculations regarding the future of the urban security landscape in the global West. [ABSTRACT FROM AUTHOR]

This paper examines the geographies of justice movements in Rotterdam in The Netherlands and Los Angeles in the United States. In their wider national and international frameworks movements in both countries continue to contest unjust forms of urbanization characterized by neoliberal initiatives that undermine the socioeconomic status of low-income residents. These movements are constituted by relations that stretch across several geographical levels. There remain, however, significant differences in their spatial organizational form: Rotterdam is characterized by loose networks of local associations which relate to constellations of nationally based Christian churches, unions, and humanist organizations, whereas networks between associations, unions, and university activists in Los Angeles have undergone institutionalization at the urban level. We show that movement territorialization is particularly evident at the urban level in Los Angeles while embedded at the national level in the shadow of state - corporatist institutional legacies and power relations in Rotterdam. By drawing upon important insights from several economic geographers, we develop a conceptual framework for explaining the spatialities of contention and contribute to contemporary controversies over relationality, territoriality, and political action at a variety of scales. A normative implication of the paper concerns the learning capacities of contesting actors to forge alliances and achieve their ambitions within path-dependent institutional frameworks.

This paper focuses on the process of institutional change at the leading ports of the United States: Los Angeles and Long Beach. In order to do so, it makes use of the structure of provision-approach and the concept of regime politics which allows for a systematic analysis and comparison. Key questions are: how are both ports institutionally structured? How do they evolve in relation to each other? And what is the role of agency in this process? The paper reveals how both ports remain institutionally different in spite of competition. This persistent institutional diversity can be explained by that fact that institutions represent territorially rooted structures of power in which competitive performance will not always be the decisive interest.

This paper explores the multiple expressions of Central American immigrant Pentecostalism in the Pico Union district of Los Angeles. Drawing on in-depth ethnographic fieldwork in three temples and informal conversations with over 30 active Pentecostals, this paper shows that Central American immigrant Pentecostals tend to congregate on the basis of “congregational homophily,” or shared social and cultural characteristics, especially in terms of age, marital status, presence of infirmities or ailments, and national/regional origin. This paper also explores the ways in which Central American immigrant Pentecostals tailor their religious practices to reflect their “congregational homophily” through the differential inclusion/exclusion of practices such as healing, “roommating,” and formal and informal discussions of shared histories. By focusing on “congregational homophily” and the active constructions and reconstructions of Central American immigrant Pentecostalism, we gain more insight into the ways some Central American immigrants negotiate their lives and experiences in the increasingly fettered social, cultural, and political topography of contemporary Los Angeles.

Long Beach, California is home to the largest population of Cambodians outside Cambodia and is the symbolic and actual center of the worldwide Cambodian diaspora. Despite the significance of this community for both Cambodians and Long Beach, little is known about the social, historical, political, and economic processes leading to its formation. This paper situates the growth of the community within particular historical moments at both national and local levels through a chronological presentation of key events from the 1950s through the 1990s. The paper provides insights into the experiences of a largely refugee population and the new Asian immigration to the United States. [ABSTRACT FROM AUTHOR]

Through narratives taken from life history interviews with an indigenous Mexican male immigrant in California, this paper examines the connection between masculinities and the learning of dominant languages associated with access to economic opportunities. In portraying the teller's engagements with work and education in both countries, these life history narratives index the way changing social contexts have caused him to emphasise different masculinities at different times in his life. Specifically, this paper explores the way a serious work injury led the teller to place new emphasis on learning English and computer skills in order to reconstruct a kind of ‘technical masculinity’ that he had previously found little scope for in the United States.

The purpose of this paper is to draw out some of the implications of the 9/11 Commission Report for California's Homeland Defense and Security and to address government failures identified in that report. The question the paper addresses is: How can we design organizational arrangements and staff them to institutionalize imagination, foster organizational adaptability, and overcome ineffective operational management? A Matrixed Networks Model is proposed to "restructure" the way California government is organized to achieve the performance objectives alluded to in the above research question.
