Species distribution modeling is used to study changes in biodiversity and species range shifts, two currently well-known manifestations of climate change. The focus of this study is to explore how distributions of suitable habitat might shift under climate change for shrub communities within the Santa Monica Mountains National Recreation Area (SMMNRA), through a comparison of community level to individual species level distribution modeling. Species level modeling is more commonly utilized, in part because community level modeling requires detailed community composition data that are not always available. However, community level modeling may better detect patterns in biodiversity. To examine the projected impact on suitable habitat in the study area, I used the MaxEnt modeling algorithm to create and evaluate species distribution models with presence only data for two future climate models at community and individual species levels. I contrasted the outcomes as a method to describe uncertainty in projected models. To derive a range of sensitivity outcomes I extracted probability frequency distributions for suitable habitat from raster grids for communities modeled directly as species groups and contrasted those with communities assembled from intersected individual species models. The intersected species models were more sensitive to climate change relative to the grouped community models. Suitable habitat in SMMNRA's bounds was projected to decline from about 30-90% for the intersected models and about 20-80% for the grouped models from its current state. Models generally captured floristic distinction between community types as drought tolerance. Overall the impact on drought tolerant communities, growing in hotter, drier habitat such as Coastal Sage Scrub, was predicted to be less than on communities growing in cooler, moister more interior habitat, such as some chaparral types. Of the two future climate change models, the wetter model projected less impact for most communities. These results help define risk exposure for communities and species in this conservation area and could be used by managers to focus vegetation monitoring tasks to detect early response to climate change. Increasingly hot and dry conditions could motivate opportunistic restoration projects for Coastal Sage Scrub, a threatened vegetation type in Southern California.

It has been identified in the literature that there exists a link between the built environment and non-motorized transport. This study aims to contribute to existing literature on the effects of the built environment on cycling, examining the case of the whole State of California. Physical built environment features are classified into six groups as: 1) local density, 2) diversity of land use, 3) road connectivity, 4) bike route length, 5) green space, 6) job accessibility. Cycling trips in one week for all children, school children, adults and employed-adults are investigated separately. The regression analysis shows that cycling trips is significantly associated with some features of built environment when many socio-demographic factors are taken into account. Street intersections, bike route length tend to increase the use of bicycle. These effects are well-aligned with literature. Moreover, both local and regional job accessibility variables are statistically significant in two adults' models. However, residential density always has a significant negatively effect on cycling trips, which is still need further research to confirm. Also, there is a gap in literature on how green space affects cycling, but the results of this study is still too unclear to make it up. By elasticity analysis, this study concludes that street intersections is the most powerful predictor on cycling trips. From another perspective, the effects of built environment on cycling at workplace (or school) are distinguished from at home. This study implies that a wide range of measures are available for planners to control vehicle travel by improving cycling-level in California.

I present a new framework for qualitative assessment of the current green purchasing practices of U.S. state governments. Increasing demand from citizens for green public purchasing has prompted state governments to adopt new, and improve existing, practices. Yet there has been little assessment of public green purchasing in academic research; what has been done has not provided the conceptual support necessary to assess green purchasing practices as a single component of the procurement process. My research aims to fill that gap by developing a conceptual framework with which to assess the status of green purchasing practices and by applying this framework to determine and describe the status of green purchasing in the five most populous U.S. states. The framework looks at state purchasing practices through the lenses of policy, policy implementation, and transparency.

Beginning in 2011, California’s most recent drought has brought four years of some of the warmest and driest seasons on record. Mendota, California in the San Joaquin Valley is a microcosm of the struggles many agriculture communities face when water resources are scarce. Known as the “cantaloupe capital of the world,” agriculture represents over half of Mendota’s economy, making unemployment one of the many challenges they face. However, community members are working to move forward and preserve the place they call home.

Medota has a population of about eleven thousand people with over 96 percent of them being Hispanic. The stories of elected officials, field workers, farmers, police, school leaders and local business owners give testament to a mounting fear for future water allocation. But their voices also give way to a shared belief—the community’s resilience will persevere through California’s drought. Mendota is presented through a multi-media piece that uses photos, videos and descriptive articles to showcase both their hardship and hope.

The public education system in the United States is one of the nation's most powerful and influential institutions. Although this system was and continues to be viewed as a societal equalizer, the institution of public education was never constructed to support equity. This paper examines educational inequity by analyzing American history state standards in Arizona, California, New Mexico, Montana, and Oklahoma. American history state standards are carefully curated to construct a dominant "American story." For this project three frameworks were utilized to analyze the five state standards: Timeframe of Inclusion, Life Domains, and Population Characterization. These three frameworks helped unpack the state standards, which overall do not holistically include Latino or Native American historical elements. This paper supports the need to reconstruct the American history state standards in Arizona, California, New Mexico, Montana, and Oklahoma to more accurately represent Native American and Latino contributions and historical elements.

Dual Language Immersion programs have been growing exponentially as a result of an urgent need for globally competent, bilingual or multilingual citizens. The US is currently facing a language deficit, which negatively affects national security, international relations and even the economy. If America wants to stay in contention as one of the strongest world powers, the US needs to foster more interest in learning foreign languages earlier and invest in the development of foreign language education. The purpose of this paper is to provide an overview of the history and implementation of different Dual Language Immersion program models. The geographical scope of the paper will cover historical background in Canada and the current implementation of Dual Language Immersion models in three Southwestern states: California, Utah and Arizona. The paper also outlines challenges related to the implementation of these dual language immersion programs.

Sentencing reform has been the subject of much debate in the 21st century and has resulted in a great deal of consternation in state and federal systems of government (Chesney-Lind, 2012). The public does not view incarceration as an important topic needing attention or requiring change, which makes invisible the needs and histories of prisoners as a consequence of not addressing them (Connor, 2001). Through an analysis of the spectrum of women’s crime, ranging from non-violent drug trafficking to homicide, I conclude within this paper that the criminal justice system was written as a male-oriented code of addressing crime, which has contributed to women being made into easier targets for arrest and female imprisonment at increasing rates for longer lengths of time.
In the last decade, California’s imprisoned population of women has increased by nearly 400% (Chesney-Lind, 2012). The focus of this thesis is to discuss the treatment—or lack thereof—of women within California’s criminal justice system and sentencing laws. By exploring its historical approach to two criminal actions related to women, the Three Strikes law (including non-violent drug crimes) and the absence of laws accounting for experiences of female victims of domestic violence who killed their abusers, I explore how California’s criminal code has marginalized women, and present a summary of the adverse effects brought about by the gender invisibility that is endemic within sentencing policies and practice. I also discuss recent attempted and successful reforms related to these issues, which evidence a shift toward social dialogue on sentencing aiming to address gender inequity in the sentencing code. These reforms were the result of activism; organizations, academics and individuals successfully raised awareness regarding excessive and undue sentencing of women and compelled action by the legislature.
By method of a feminist analysis of these histories, I explore these two pertinent issues in California; both are related to women who, under harsh sentencing laws, were incarcerated under the state’s male-focused legislation. Responses to the inequalities found in these laws included attempts toward both visibility for women and reform related to sentencing. I analyze the ontology of sentencing reform as it relates to activism in order to discuss the implications of further criminal code legislation, as well as the implications of the 2012 reforms in practice. Through the paper, I focus upon how women have become a target of arrest and long sentences not because they are strategically arrested to equalize their representation behind bars, but because the “tough on crime” framework in the criminal code cast a wide and fixed net that incarcerated increasingly more women following the codification of both mandatory minimums and a male-oriented approach to sentencing (Chesney-Lind et. al, 2012).

In its 1993 decision Daubert v. Merrell Dow Pharmaceuticals, Inc., the US Supreme Court established the Daubert Standard for evaluating the admissibility of scientific knowledge as evidence in US federal courts. When it began in trial court, the case addressed whether or not Bendectin, an anti-nausea medication taken during pregnancy, caused birth defects. However, after the trial court dismissed the case for lack of admissible evidence, Daubert v. Merrell Dow Pharmaceuticals, Inc. advanced through appeals courts to the US Supreme Court, where the Justices defined the criteria by which scientific knowledge, which for them included a least theories based on evidence, expert testimony from scientists, and scientific techniques, could be introduced and used in court cases as evidence. The Daubert Standard states that the judge of a case is responsible for determining what claims are admissible as scientific knowledge and as evidence in the case. The admissibility should be determined by the falsifiability of the claims, by whether or not they had passed peer reviewed, by the general scientific acceptance of the claims, and for techniques, by their error rates of the techniques. Daubert v. Merrell Dow Pharmaceuticals, Inc. set a landmark precedent in the US judicial system and influenced most subsequent legal cases that appealed to science to establish facts in trials.

Sindell v. Abbott Laboratories was a 1980 California case that established the doctrine of market share liability for personal injury cases. For such liability, when a drug causes personal injury and the manufacturer of the drug cannot be identified, each producer is responsible for paying the settlement in proportion to the percentage of the market they supplied. Judith Sindell and Maureen Rogers brought the case against the producers of diethylstilbestrol (DES), which their mothers had taken during pregnancy to prevent miscarriage and other complications. Sindell and Rogers alleged that their mothers' ingestions of DES during pregnancy later caused Sindell and Rogers to develop cancers at the onset of puberty, but they could not identify the specific manufacturer of the drug. The market share liability ruling in Sindell allowed millions of DES-affected individuals to seek restitution for reproductive cancers caused by prenatal exposure to DES.

In 1928 Ezra Seymour Gosney founded the non-profit Human Betterment Foundation (HBF) in Pasadena, California to support the research and publication of the personal and social effects of eugenic sterilizations carried out in California. Led by director Gosney and secretary Paul Popenoe, the HBF collected data on thousands of individuals in California who had been involuntarily sterilized under a California state law enacted in 1909. The Foundation's assets were liquidated following Gosney's death in 1942. In 1943, Gosney's daughter donated the remaining assets to the California Institute of Technology (Caltech) in Pasadena, California to establish the Gosney research fund for biological research. Between 1928 and 1942, the HBF published extensively on what they believed to be the benefits of sterilization to both patient and society. The HBF and its members existed within the larger context of the American eugenics movement and scientific institutions, including the Eugenics Record Office at Cold Spring Harbor Laboratory in Cold Spring Harbor, New York, which bolstered the movement's goals of the control of human reproduction and human heredity. Moreover, the model sterilization legislation written by the HBF was disseminated throughout the world to eugenics enthusiasts eager to pass laws limiting the reproduction of people they considered to be unfit.
