    2013-02-01

    California law has standards for physical education (PE) instruction in K-12 public schools; audits found that the Los Angeles Unified School District did not enforce the standards. In 2009, the district adopted a PE policy to comply with these standards. This study aimed to evaluate the outcomes of the PE policy in district schools. PE class observations were conducted using the System for Observing Fitness Instruction Time in the 2010-2011 and 2011-2012 school years in an income-stratified random sample of 34 elementary, middle, and high schools to assess changes in PE class size, class duration, and time students spent in moderate to vigorous physical activity. PE class duration increased in high-income elementary schools. Mean class size decreased in low-income middle schools. There was limited implementation of the PE policy 2 years after passage. Opportunities exist to continue monitoring and improving PE quantity and quality.

  10. Starting school healthy and ready to learn: using social indicators to improve school readiness in Los Angeles County.

    Science.gov (United States)

    Wold, Cheryl; Nicholas, Will

    2007-10-01

    School readiness is an important public health outcome, determined by a set of interdependent health and developmental trajectories and influenced by a child's family, school, and community environments. The same factors that influence school readiness also influence educational success and health throughout life. A California cigarette tax ballot initiative (Proposition 10) created new resources for children aged 0 to 5 years and their families statewide through county-level First 5 commissions, including First 5 LA in Los Angeles County. An opportunity to define and promote school readiness indicators was facilitated by collaborative relationships with a strong emphasis on data among First 5 LA, the Children's Planning Council, and the Los Angeles County Public Health Department, and other child-serving organizations. A workgroup developed school readiness goals and indicators based on recommendations of the National Education Goals Panel and five key domains of child well-being: 1) good health, 2) safety and survival, 3) economic well-being, 4) social and emotional well-being, and 5) education/workforce readiness. The Los Angeles County Board of Supervisors and First 5 LA Commission adopted the school readiness indicators. First 5 LA incorporated the indicators into the results-based accountability framework for its strategic plan and developed a community-oriented report designed to educate and spur school readiness-oriented action. The Los Angeles County Board of Supervisors approved a countywide consensus-building plan designed to engage key stakeholders in the use of the indicators for planning, evaluation, and community-building activities. School readiness indicators in Los Angeles County represent an important step forward for public health practice, namely, the successful blending of an expanded role for assessment with the ecological model.

    1999-04-01

    The UCLA School of Medicine's Interactive Multi-media Exercises (IMMEX) Project began its outreach into pre-college education in the Los Angeles area in 1993. The project provides a model in which software and technology are effectively intertwined with teaching, learning, and assessment (of both students' and teachers' performances) in the classroom. The project has evolved into a special collaboration between the medical school and Los Angeles teachers. UCLA faculty and staff work with science teachers and administrators from elementary, middle, and high schools. The program benefits ethnically and racially diverse groups of students in schools ranging from the inner city to the suburbs. The project's primary goal is to use technology to increase students' achievement and interest in science, including medicine, and thus move more students into the medical school pipeline. Evaluations from outside project evaluators (West Ed) as well as from teachers and IMMEX staff show that the project has already had a significant effect on teachers' professional development, classroom practice, and students' achievement in the Los Angeles area.

  12. Capistrano unified school district works with San Onofre NGS

    International Nuclear Information System (INIS)

    Osterfield, M.A.; Cramer, E.N.

    1992-01-01

    A unique arrangement has the science coordinator for Capistrano Unified School District's (CUSD) grades kindergarten through eight (K-8) as a part-time contract employee at San Onofre Nuclear Generating Station (SONGS). The purpose is to assess the science capabilities at SONGS useful to CUSD teachers and to assist in making them available. This is different from the usual single-teacher renewal program or from part-time employment. This creates several unique situations for SONGS and the 23 K-8 schools in CUSD, supplementing the existing program of optional science field trips to SONGS. This approach also interests the developing mind in science before being turned off by uninteresting, user-unfriendly, bookish approaches

  13. Understanding parents' concerns about their children with autism taking public school transportation in Los Angeles County.

    Science.gov (United States)

    Angell, Amber M; Solomon, Olga

    2018-05-01

    There are a number of recent US news media reports of children and youth with autism becoming lost, injured, or even dying while taking public school transportation, yet research on this problem is scarce. This ethnographic study examines the experiences of 14 parents whose children with autism take public school transportation in Los Angeles County. We present two case studies of children with autism being "lost" while in transit from school to home on the bus to (1) describe how the situation was experienced, responded to, and managed by the parents; (2) consider three interrelated themes that emerged from interviews with 14 parents, related to children's safety, independence, and participation, across multiple contexts and analytic levels; and (3) discuss the findings in relation to US news media reports of incidents involving children with autism on school buses to identify specific weaknesses in school transportation infrastructure, particularly in the context of privatization, that create conditions in which children with autism can "fall through the cracks" in potentially life-threatening ways. We argue that there is a critical need to address transportation accessibility for individuals on the autism spectrum to ensure their safety and support their independence and community participation.

  3. The Sexuality Education Initiative: a programme involving teenagers, schools, parents and sexual health services in Los Angeles, CA, USA.

    Science.gov (United States)

    Marques, Magaly; Ressa, Nicole

    2013-05-01

    In response to abstinence-only programmes in the United States that promote myths and misconceptions about sexuality and sexual behaviour, the comprehensive sexuality education community has been sidetracked from improving the sexuality education available in US schools for almost two decades now. Much work is still needed to move beyond fear-based approaches and the one-way communication of information that many programmes still use. Starting in 2008 Planned Parenthood Los Angeles developed and launched a teen-centred sexuality education programme based on critical thinking, human rights, gender equality, and access to health care that is founded on a theory of change that recognises the complex relationship between the individual and broader environment of cultural norms, socio-economic inequalities, health disparities, legal and institutional factors. The Sexuality Education Initiative is comprised of a 12-session classroom sexuality education curriculum for ninth grade students; workshops for parents; a peer advocacy training programme; and access to sexual health services. This paper describes that experience and presents the rights-based framework that was used, which seeks to improve the learning experience of students, strengthen the capacity of schools, teachers and parents to help teenagers manage their sexuality effectively and understand that they have the right to health care, education, protection, dignity and privacy.

    Schools officials owe a duty of care to all the students in their custody. An emerging, but not unanimous, judicial consensus seems to agree that school board officials have a greater legal duty when supervising students with disabilities. A case on this important issue arose in "Jennifer C. v. Los Angeles Unified School District"…

    2015-01-02

    On August 4, 2014, the Acute Communicable Disease Control Program of the Los Angeles County Department of Public Health received a report of three aseptic meningitis cases among football players at a county high school. An investigation was conducted to determine the extent of the outbreak, identify potential exposures, and recommend control measures. An outbreak-associated aseptic meningitis case was defined as an illness of any team or family member with onset during July 28-August 11 with 1) cerebrospinal fluid pleocytosis and negative bacterial culture or 2) an emergency department visit with headache, fever, and stiff neck. Ten cases were identified; nine in males, and one in a female; patient ages ranged from 13 to 17 years. All the patients sought care at an emergency department, and five were hospitalized, resulting in 12 total hospital days. All 10 patients have recovered. Eight patients were football players, and two were siblings of football players. The most affected subgroup was the junior varsity football team, with seven cases out of 57 players (attack rate = 12.3%); the relative risk for aseptic meningitis was higher among players who were linemen than among those who were not linemen (relative risk = 5.4 [p = 0.03]). Of the 10 patients, eight tested positive by polymerase chain reaction for enterovirus, and two were not tested. Echovirus testing was performed at the California Viral and Rickettsial Disease Laboratory. Of the eight specimens testing positive for enterovirus, seven tested positive for echovirus 30, and one specimen could not be typed because of insufficient quantity.

  14. Effectiveness of the Solar Panels in the Castro Valley Unified School District Based on Projected Amount of Energy to be Produced

    Science.gov (United States)

    Sparks, J. R.; Palmer, T. C.; Siegel, A. P.

    2014-12-01

    In recent years Americans have warmed to the idea of installing solar panels to their homes and businesses. These panels help reduce the cost of receiving energy from power plants that lose a lot of energy in transportation. These power plants provide energy by burning gas or coal producing emissions that add to the growing problem of pollution and global warming. In 2010 the Castro Valley Unified School District decided to add solar panels to Canyon Middle School, Castro Valley High School, and Castro Valley Adult School. We researched whether the solar panels reached their projected amount of energy (74%) for the sites where the panels were placed. The solar panels at all three sites were found to exceed these projected amounts. The solar panels at each site produce a little over 74% for the each school.

    2018-01-01

    Full Text Available The preponderance of studies about viceregal angelic series, and the widespread belief that the representation of apocryphal angels is a specific peculiarity of viceregal angelology, have created such a close relation between it and the apocryphal angels, that they are even considered as synonymous. However, both the texts and the presence of this angels in the spanish convents of the XVII century, evidence that the apocryphal angels appeared and they were represented in Spain long before that in its american viceregal. Therefore, it is here where their origins and their meaning should be sought.

    In the early 1890s, Edward L Doheny, a mining prospector down on his luck, observed residents of Los Angeles gathering brea from the area's tar pits for use as fuel in coal-scarce California. Realizing that this crude tar was petroleum that had congealed upon contact with the open air, Doheny explored the residential neighborhood near Westlake Park, pooled resources with Charles A Canfield, an old mining crony, and purchased a city lot for $400. This paper reports that drilling wells in the Los Angeles City field posed the problem of making oil production compatible with urban living. Residents had to deal with noise, dirt, traffic, odors, and waste disposal. At least one solution to the waste disposal problem proved unique. A homeowner with a rig in his backyard had no place for a sump in which to run waste water and mud. However, his house had a basement, and that's where the mud went

  19. BUSINESS ANGELS AND INVESTMENTS

    Directory of Open Access Journals (Sweden)

    CLAUDIA ISAC

    2015-12-01

    Full Text Available In this paper we have synthesized a part of legislative and conceptual elements linked to a new model of investors which is increasingly publicized in Romania, business angels. In the first part of the paper we have presented theoretical notions related to the concept of investments and to the importance of the investment decision at managerial level. Modern investments regarding, in particular, the launch of some products and services as well as the start-up of companies are dependent on the source of funding that can take many forms, one of them being that of business angels. Thus, the legislative framework in Romania represents an opportunity not only for those looking for sources of financing but also for investors seeking more flexible and more advantageous ways to place capital. Thus, at the end of the paper we have tried to reveal the main fiscal facilities from EU member countries in order to be studied by any business angel and the most important organizations offering information on the business angels’ portfolio.

    International Nuclear Information System (INIS)

    Georgi, H.

    1980-01-01

    Unified gauge theories such as SU(5) of particle interactions are built on the colour SU(3) and SU(2) x U(1) gauge theories which apparently describe strong and weak and electromagnetic interactions at distances as small as 10 -16 cm. In this article the classical reasons for going beyond SU(3)xSU(2)xU(1) to a fully unified theory such as SU(5) are reviewed, and a new reason formulated. A class of imaginary worlds similar to our own is considered and it is shown that unification is possible only in ours. This suggests that the low-energy interactions are unique in that they are constructed to make unification possible. (author)

    2013-04-01

    Century old GR fails to unify quantum physics, nuclear force or distinguish between the mass of living bodies from inert mass. Probabilistic gravity [1] explains strong coupling (nuclear force). The natural log of the age of the universe, 10E60 in Planck times, equaling 137 (1/Alpha) extends physics to deeper science, if we stand on the shoulders of giants like Feynman and Gamow. Implications of [1] are that it is not the earth, but M and S numbers of the particles of the earth are remotely interacting with corresponding numbers of the particles of the moon and the sun respectively, neglecting other heavenly bodies in this short draft. This new physics is likely to enable creative scientific minds to throw light on a theoretical basis for an otherwise arbitrary cosmological constant, uniformity of microwave background, further vindication of Boltzmann, quantum informatics, Einstein’s later publicized views and more, eliminating the need to spend money for implicitly nonexistent quantum gravity and graviton.[4pt] [1] Journal of Physical Science and Applications 2 (7) (2012) 265-268.

    In the late 1950s and early 1960s, during the height of protests and actions by civil rights activists against de facto school segregation in the Los Angeles area, the residents of a group of small cities fought to break away from the Los Angeles City Schools and create a new, independent school district. If established, the district would serve white pupils nearly exclusively, preserving and reinforcing racially segregated schools in the area. Proponents of the plan were residents of the maj...

    The new film Angels & Demons starring Tom Hanks and directed by Ron Howard is being premiered worldwide on 15 May, but you could see it 10 days earlier at a special preview screening as the CERN Press Office has a limited number of tickets to give away. Preview of the new CERN website to be published on 5 May. Opinion is split among CERNois when talking about Dan Brown’s book Angels & Demons. Should he be praised for bringing particle physics into the spotlight or should he be demonised for the ‘creative liberties’ he took - for example, although it would be useful for the international collaborations, CERN doesn’t actually have its own private airport and supersonic jet. But love it or hate it, with the upcoming release of the multi-million dollar Hollywood film adaptation, Angels & Demons will introduce a huge new audience to CERN.

    This paper reports on a pedagogical introduction that attempts to unify the strong and electroweak interactions. Unifying groups discussed include SU(5), SO(10), and E 6 . Particular attention is paid to the questions of whether the low-energy gauge group (that accessible at accelerator experiments in the foreseeable future) extends beyond SU(3) x SU(2) L x U(1). Low-energy studies of neutral-current effects, direct production of gauge bosons, and new fermions all can shed light on this question. Brief remarks are made concerning the role of monopoles, cosmic strings, baryogenesis, supersymmetry, and higher dimensions in this program

    In this talk I discuss the present status of these theories and of their observational and experimental implications. In section II, I briefly review the standard SU 3 sup(c) x SU 2 x U 1 model of the strong and electroweak interactions. Although phenomenologically successful, the standard model leaves many questions unanswered. Some of these questions are addressed by grand unified theories, which are defined and discussed in Section III. The Georgi-Glashow SU 5 model is described, as are theories based on larger groups such as SO 10 , E 6 , or SO 16 . It is emphasized that there are many possible grand unified theories and that it is an experimental problem not only to test the basic ideas but to discriminate between models. (orig./HSI)

  7. A unified universe

    DEFF Research Database (Denmark)

    2018-01-01

    We present a unified evolution of the universe from very early times until the present epoch by including both the leading local correction R2 and the leading non-local term R1□2R to the classical gravitational action. We find that the inflationary phase driven by R2 term gracefully exits...... in a transitory regime characterized by coherent oscillations of the Hubble parameter. The universe then naturally enters into a radiation dominated epoch followed by a matter dominated era. At sufficiently late times after radiation–matter equality, the non-local term starts to dominate inducing an accelerated...... expansion of the universe at the present epoch. We further exhibit the fact that both the leading local and non-local terms can be obtained within the covariant effective field theory of gravity. This scenario thus provides a unified picture of inflation and dark energy in a single framework by means...

    Recent decades have seen research into the conditions necessary for the formation of the monotonic potential shape in the sheath, appearing at the plasma boundaries like walls, in fluid, and kinetic approximations separately. Although either of these approaches yields a formulation commonly known as the much-acclaimed Bohm criterion (BC), the respective results involve essentially different physical quantities that describe the ion gas behavior. In the fluid approach, such a quantity is clearly identified as the ion directional velocity. In the kinetic approach, the ion behavior is formulated via a quantity (the squared inverse velocity averaged by the ion distribution function) without any clear physical significance, which is, moreover, impractical. In the present paper, we try to explain this difference by deriving a condition called here the Unified Bohm Criterion, which combines an advanced fluid model with an upgraded explicit kinetic formula in a new form of the BC. By introducing a generalized polytropic coefficient function, the unified BC can be interpreted in a form that holds, irrespective of whether the ions are described kinetically or in the fluid approximation.

  14. Beyond the Unified Model

    Science.gov (United States)

    Frauendorf, S.

    2018-04-01

    The key elements of the Unified Model are reviewed. The microscopic derivation of the Bohr Hamiltonian by means of adiabatic time-dependent mean field theory is presented. By checking against experimental data the limitations of the Unified Model are delineated. The description of the strong coupling between the rotational and intrinsic degrees of freedom in framework of the rotating mean field is presented from a conceptual point of view. The classification of rotational bands as configurations of rotating quasiparticles is introduced. The occurrence of uniform rotation about an axis that differs from the principle axes of the nuclear density distribution is discussed. The physics behind this tilted-axis rotation, unknown in molecular physics, is explained on a basic level. The new symmetries of the rotating mean field that arise from the various orientations of the angular momentum vector with respect to the triaxial nuclear density distribution and their manifestation by the level sequence of rotational bands are discussed. Resulting phenomena, as transverse wobbling, rotational chirality, magnetic rotation and band termination are discussed. Using the concept of spontaneous symmetry breaking the microscopic underpinning of the rotational degrees is refined.

    Tohoku University was the first National University to admit three women students in Japan in 1913. To support the university's traditional ``open-door'' policy, various projects have been promoted throughout the university since its foundation. A government plan, the Third-Stage Basic Plan for Science and Technology, aims to increase the women scientist ratio up to 25% nationwide. In order to achieve this goal, the Tohoku Women's Hurdling Project, funded by the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT), was adopted in 2006. This project is threefold: support for child/family, improvement of facilities, and support for the next generation, which includes our Science Angels program. ``Science Angels'' are women PhD students appointed by the university president, with the mission to form a strong support system among each other and to become role-models to inspire younger students who want to become researchers. Currently, 50 women graduate students of the natural sciences are Science Angels and are encouraged to design and deliver lectures in their areas of specialty at their alma maters. Up to now, 12 lectures have been delivered and science events for children in our community have been held-all with great success.

    Science.gov (United States)

    Balcerak, Ernie

    2012-01-01

    Laboratory and field studies have indicated that glyoxal (chemical formula OCHCHO), an atmospheric oxidation product of isoprene and aromatic compounds, may contribute to secondary organic aerosols in the atmosphere, which can block sunlight and affect atmospheric chemistry. Some aerosols are primary aerosols, emitted directly into the atmosphere, while others are secondary, formed through chemical reactions in the atmosphere. Washenfelder et al. describe in situ glyoxal measurements from Pasadena, Calif., near Los Angeles, made during summer 2010. They used three different methods to calculate the contribution of glyoxal to secondary atmospheric aerosol and found that it is responsible for 0-0.2 microgram per cubic meter, or 0-4%, of the secondary organic aerosol mass. The researchers also compared their results to those of a previous study that calculated the glyoxal contribution to aerosol for Mexico City. Mexico City had higher levels of organic aerosol mass from glyoxal. They suggest that the lower contribution of glyoxal to aerosol concentrations for Los Angeles may be due to differences in the composition or water content of the aerosols above the two cities.

After the extraordinary success of Dan Brown's "Da Vinci Code", one of his earlier novels "Angels & Demons", published in 2000, has now become a best seller and has generated a flood of questions about CERN. This detective story is about a secret society, the Illuminati, who wish to destroy the Vatican with an antimatter bomb stolen from - wait for it - CERN! Inevitably, CERN has been bombarded with calls about the technologies described in the novel that are supposed to be under development in the Laboratory. The Press Office has always explained that, even if the novel appears to be very informative, it is in fact a mixture of fact and fiction.

  18. PORTRAIT IN LITERATURE AND GRAPHIC ART: THE CASE OF THE FIERY ANGEL

    Directory of Open Access Journals (Sweden)

    2017-06-01

    Full Text Available This essay analyzes portraits in several editions of The Fiery Angel published during This essay analyzes portraits in several editions of The Fiery Angel published during Bryusov’s lifetime and claims that the portrait was as a universal point of convergence for verbal and visual arts. The dialogue between literature and graphics in the context of the synthesis of arts sheds new light on the possibilities for interdisciplinary research. The time of the “beautiful book” was a time of great artists and illustrators who introduced the peculiarities of their own style and the manner of their artistic schools into their art. Books were commonly decorated with vignettes and famous paintings. Portraits, as well as plates in general, were of the highest quality. They were ornamental and illusory, with every minute detail finely drawn out. Yet, in the second edition of the novel Bryusov deliberately included medieval engravings and portraits. A comparative analysis of the verbal portraits in The Fiery Angel and engraved portraits in the book (Ruprecht, Heinrich, Faust, Mephistopheles, Renata, and Madiel demonstrates that both the main and the secondary characters of the novel are picturesque and multidimensional whereas the xylographic portraits rather reveal conventionality and simplicity of the medieval time. This way Bryusov was seeking to debase clichе’s, especially as regards Agrippa von Nettesheim and Faust: according to Bryusov, the character of Agrippa had already become a clichе’d image and so was the popular engraving of the scientist that he reproduced in the middle of the sixth chapter of the 1909 edition. Juxtaposing the verbal and the graphic portraits in The Fiery Angel helps us better understand the function of the verbal portrait in a Symbolist text that was determined by the author’s design, on the one hand, and by various “instruments” of different arts, on the other.

    A standard SU(2)xU(1) theory is discussed. It is based on an assumption that the left components of fields form doublets, and the rignt ones - singlets. From the weak interaction lagrangian an expression is obtained for the effective hamiltonian describing neutrino-lepton processes. The results of discussing the experimental status of the unified theories of weak and electromagnetic interactions are in agreement with the simplest version of the unified theories - the Weinberg-Salam theory. It has been noted that the accuracy of the experiments (not exceeding 20%) is insufficient and no information is available on diagonal terms of the hamiltonian

  4. On the History of Unified Field Theories

    Directory of Open Access Journals (Sweden)

    Goenner Hubert F.M.

    2004-01-01

    Full Text Available This article is intended to give a review of the history of the classical aspects of unified field theories in the 20th century. It includes brief technical descriptions of the theories suggested, short biographical notes concerning the scientists involved, and an extensive bibliography. The present first installment covers the time span between 1914 and 1933, i.e., when Einstein was living and working in Berlin - with occasional digressions into other periods. Thus, the main theme is the unification of the electromagnetic and gravitational fields augmented by short-lived attempts to include the matter field described by Schrödinger's or Dirac's equations. While my focus lies on the conceptual development of the field, by also paying attention to the interaction of various schools of mathematicians with the research done by physicists, some prosopocraphical remarks are included.

    1994-05-01

    Full Text Available Recent American science fiction (which commercially dominates world science fiction incorporates two schools of thought, ‘cyberpunk' and ‘hard SF’. which may be read to embody, respectively, radical/liberal and patriotic/ conservative propaganda. This article, after attempting to define aspects of these schools, examines Queen of Angels by Greg Bear (who before producing that text had been a proponent of hard SF. This text is shown to have strong elements of cyberpunk (possibly, to judge by one critical review, appealing to a cyberpunk audience but to have transformed and inverted the radical and liberal themes of cyberpunk into conservative themes. The text thus illuminates philosophical and technical differences between the schools. It is suggested that the imagery of cyberpunk, and perhaps that of science fiction in general, is liable to such reversals of ideological significance.

    We present a unified description of effective interaction theories in both algebraic and graphic representations. In our previous work, we have presented the Rayleigh–Schrödinger and Bloch perturbation theories in a unified fashion by introducing the main frame expansion of the effective interaction. In this work, we start also from the main frame expansion, and present various nonperturbative theories in a coherent manner, which include generalizations of the Brandow, Brillouin–Wigner, and Bloch–Horowitz theories on the formal side, and the extended Krenciglowa–Kuo and the extended Lee–Suzuki methods on the practical side. We thus establish a coherent and comprehensive description of both perturbative and nonperturbative theories on the basis of the main frame expansion.

  16. Split supersymmetry in unified models

    International Nuclear Information System (INIS)

    Dutta, Bhaskar; Mimura, Yukihiro

    2005-01-01

    In the context of split supersymmetry, the gaugino mass spectrum seems to be very important to satisfy the dark matter content of the universe and the gauge coupling unification. In this Letter, we have considered various sources of gaugino masses in the context of unified models. We show that the gaugino mass spectrum varies in different unification pictures. In the context of SU(5), we have found that the bino/wino mass ratio can be close to one at the weak scale which is helpful to satisfy the WMAP data. The gluino/wino mass ratio is also different from the usual scenario of unified gaugino masses. The gaugino masses can be around one TeV and m SUSY is chosen so that the gluino mass does not create any cosmological problem. In the context of the Pati-Salam model, we show that the gluino mass can be made very heavy even after maintaining the unification of the gauge couplings

    Although dental decay is preventable, it remains the most common pediatric chronic disease. We describe a public health approach to implementing a scalable and sustainable school-based oral health program for low-income urban children. The Los Angeles Trust for Children's Health, a nonprofit affiliated with the Los Angeles Unified School District, applied a public health model and developed a broad-based community-coalition to a) establish a District Oral Health Nurse position to coordinate oral health services, and b) implement a universal school-based oral health screening and fluoride varnishing program, with referral to a dental home. Key informant interviews and focus groups informed program development. Parent surveys assessed preventative oral health behaviors and access to oral health services. Results from screening exams, program costs and rates of reimbursement were recorded. From 2012 to 2015, six elementary schools and three dental provider groups participated. Four hundred ninety-one parents received oral health education and 89 served as community oral health volunteers; 3,399 screenings and fluoride applications were performed on 2,776 children. Sixty-six percent of children had active dental disease, 27 percent had visible tooth decay, and 6 percent required emergent care. Of the 623 students who participated for two consecutive years, 56 percent had fewer or no visible caries at follow-up, while only 17 percent had additional disease. Annual program cost was $69.57 per child. Using a broad based, oral health coalition, a school-based universal screening and fluoride varnishing program can improve the oral health of children with a high burden of untreated dental diseases. © 2017 American Association of Public Health Dentistry.

    The objective of this article is to describe chiropractic professional identity as espoused by the Los Angeles College of Chiropractic. Professional identity is a construct that begins formation prior to career selection, can be considered the backbone of health care education, and has been linked to career success. Los Angeles College of Chiropractic's professional identity is shaped by a philosophy of health care that is focused on vitalism, holism, naturalism, therapeutic conservatism, critical rationalism, phenomenology, humanism, and interprofessionalism. Other distinguishing aspects include portal-of-entry professionals with broad diagnostic skills; a focus on spine care; promotion of public-health; and delivery of manual treatments. The chiropractic professional identity at the Los Angeles College of Chiropractic focuses on serving the needs of the people who entrust their health to its graduates and will continue to evolve on the basis of many factors, such as politics, social perceptions, and economic conditions.

    2007-06-01

    As the first generation of women who received cosmetic breast implants ages, questions remain about cancer risk. This study is an update of the Los Angeles Augmentation Mammaplasty Study and examines cancer risk among women with long-term exposure to breast implants. The authors conducted a record linkage cohort study of patients with cosmetic breast implants by abstracting from records of the private practices of 35 board-certified plastic surgeons in Los Angeles County, California. They included 3139 Caucasian women who received cosmetic breast implants between 1953 and 1980. Spanish-surnamed women, nonresidents of Los Angeles County, and patients with prior subcutaneous mastectomy or breast cancer were excluded. Cancer outcomes through 1994 were ascertained through record linkage with the Los Angeles County Cancer Surveillance Program. With a mean follow-up period of 15.5 years, 43 cases of breast cancer were observed, compared with 62.6 expected, based on Los Angeles County population-based incidence rates (standardized incidence ratio, 0.69; 95% CI, 0.50 to 0.93). Significant increases were observed for cancer of the lung and bronchus (standardized incidence ratio, 2.14; 95% CI, 1.42 to 3.09) and vulvar cancer (standardized incidence ratio, 3.47; 95% CI, 1.39 to 7.16). The breast cancer results of this study are consistent with the previous reports of the Los Angeles study as well as with several other long-term cohort studies. Lung cancer has previously been found to be increased in this cohort and also in some, but not most, other studies. The increased risk of vulva cancer has previously been observed in this cohort and just one other.

    We apply the Skyrme model to dense hadronic matter, which provides a unified approach to high density, valid in the large N c limit. In our picture, dense hadronic matter is described by the classical soliton configuration with minimum energy for the given baryon number density. By incorporating the meson fluctuations on such ground state we obtain an effective Lagrangian for meson dynamics in a dense medium. Our starting point has been the Skyrme model defined in terms of pions, thereafter we have extended and improved the model by incorporating other degrees of freedom such as dilaton, kaons and vector mesons

    Objectives. We examined correlations between gender, race, sexual identity, and technology use, and patterns of cyberbullying experiences and behaviors among middle-school students. Methods. We collected a probability sample of 1285 students alongside the 2012 Youth Risk Behavior Survey in Los Angeles Unified School District middle schools. We used logistic regressions to assess the correlates of being a cyberbully perpetrator, victim, and perpetrator–victim (i.e., bidirectional cyberbullying behavior). Results. In this sample, 6.6% reported being a cyberbully victim, 5.0% reported being a perpetrator, and 4.3% reported being a perpetrator–victim. Cyberbullying behavior frequently occurred on Facebook or via text messaging. Cyberbully perpetrators, victims, and perpetrators–victims all were more likely to report using the Internet for at least 3 hours per day. Sexual-minority students and students who texted at least 50 times per day were more likely to report cyberbullying victimization. Girls were more likely to report being perpetrators–victims. Conclusions. Cyberbullying interventions should account for gender and sexual identity, as well as the possible benefits of educational interventions for intensive Internet users and frequent texters.

  9. Evidence of inadequate ventilation in portable classrooms: results of a pilot study in Los Angeles County.

    Shendell, D G; Winer, A M; Weker, R; Colome, S D

    2004-06-01

    The prevalence of prefabricated, portable classrooms (portables) for United States public schools has increased; in California, approximately one of three students learn inside portables. Limited research has been conducted on indoor air and environmental quality in American schools, and almost none in portables. Available reports and conference proceedings suggest problems from insufficient ventilation due to poor design, operation, and/or maintenance of heating, ventilation and air conditioning (HVAC) systems; most portables have one mechanical, wall-mounted HVAC system. A pilot assessment was conducted in Los Angeles County, including measurements of integrated ventilation rates based on a perfluorocarbon tracer gas technique and continuous monitoring of temperature (T) and relative humidity (RH). Measured ventilation rates were low [mean school day integrated average 0.8 per hour (range: 0.1-2.9 per hour)]. Compared with relevant standards, results suggested adequate ventilation and associated conditioning of indoor air for occupant comfort were not always provided to these classrooms. Future school studies should include integrated and continuous measurements of T, RH, and ventilation with appropriate tracer gas methods, and other airflow measures. Adequate ventilation has the potential to mitigate concentrations of chemical pollutants, particles, carbon dioxide, and odors in portable and traditional classrooms, which should lead to a reduction in reported health outcomes, e.g., symptoms of 'sick building syndrome', allergies, asthma. Investigations of school indoor air and environmental quality should include continuous temperature and relative humidity data with inexpensive instrumentation as indicators of thermal comfort, and techniques to measure ventilation rates.

  12. Towards a Unified Programming Language

    DEFF Research Database (Denmark)

    Madsen, Ole Lehrmann

    2000-01-01

    The goal of research in programming languages should be to develop languages that integrates the best of concepts and constructs from the various programming paradigms. We do not argue for a multi-paradigm language, where the programmer alternates between the different paradigms/styles. Instead, we...... find that the languages of the future should integrate the best available concepts and constructs in such a way that the programmer does not think of multiple paradigms when using a given language. In this paper, we describe to what extent the BETA language has been successful in obtaining a unified...... style and where more research is needed. In addition to traditional paradigms such as object-oriented-, imperative-functional- and logic programming, we also discuss concurrent programming and prototype-based programming. We discuss language features such as the BETA pattern construct, virtual...

  13. A unified plant information network

    1986-01-01

    Technology is bringing power plants fully into the age of computerization. Microcomputers, data base managers, networking, and friendly, expert software are principal technology factors. Monitoring will improve, and the number and power of computers is increasing. The huge information flow will cause computers to be integrated into a communication network. The total plant operating triangle includes process, engineering, and management systems. The total network will integrate all of these into a Total Unified Plant Information Network (TUPIN). Software will take the type of information beyond monitored data. Analysis will improve through direct access to logical, physical, and procedural models by end users. Information management will improve through widespread use of hierarchical, relational, and expert data base managers. Expert systems will aid in diagnostics and interpretation. The goal is to automate plant operations to enhance safety and performance and to reduce cost by making both the plants and the personnel more expert

  14. Cosmology and unified gauge theory

    Science.gov (United States)

    Oraifeartaigh, L.

    1981-09-01

    Theoretical points in common between cosmology and unified gauge theory (UGT) are reviewed, with attention given to areas of one which have proven useful for the other. The underlying principles for both theoretical frameworks are described, noting the differences in scale, i.e., 10 to the 25th cm in cosmology and 10 to the -15th cm for UGT. Cosmology has produced bounds on the number of existing neutrino species, and also on the mass of neutrinos, two factors of interest in particle physics. Electrons, protons, and neutrinos, having been spawned from the same massive leptons, each composed of three quarks, have been predicted to be present in equal numbers in the Universe by UGT, in line with necessities of cosmology. The Grand UGT also suggests specific time scales for proton decay, thus accounting for the observed baryon assymmetry.

  15. Unifying physical concepts of reality

    1983-08-01

    Physics may be characterized as the science of matter and energy. It anchors the two ends of the frontiers of science: the frontier of the very small and the frontier of the very large. All of the phenomena that we observe and study at the frontiers of science - all external experiences - are manifestations of matter and energy. One may, therefore, use physics to exemplify both the diversity and unity of science. This theme will be developed in two separate examples: first by sketching, very briefly, the historical origins of frontiers of the very small and very large and the converging unity of these two frontiers; and then by describing certain unifying concepts that play a central role in physics and provide a framework for relating developments in different sciences.

  16. Phenomenology of unified gauge theories

    Part I of these lectures treats the standard Glashow-Weinberg-Salam model of weak and electromagnetic interactions, discussing in turn its basic structure and weak neutral currents, charged currents, mixing angles and CP violation, and the phenomenology of weak vector and Higgs bosons. Part II of the lectures discusses the structure of theories of dynamical symmetry breaking such as technicolour, phenomenological consequences, frustrations and alternatives. The third part of these lectures offers the standard menu of grand unified theories (GUTs) of the strong, weak and electromagnetic interactions, including an hors d'oeuvre of constraints on the parameters of the standard model, a main course of baryon number violating processes, and desserts which violate lepton number and CP. The fourth and final part goes through different attempts to remedy the inadequacies of previous theories by invoking supersymmetry and reaching out towards gravitation. (orig./HSI)

  19. A unifying philosophy of governance

    Directory of Open Access Journals (Sweden)

    Sankarshan Acharya

    2012-09-01

    Full Text Available Bertrand Russell won Nobel Prize for arguing that science has triumphed over religion. Since religions are based on god, Russell’s argument implies that science has triumphed over both religion and god. But neither Russell nor anyone else has ever defined religion and god, rationally. The assertion about triumph of science (which is founded on rationality over concepts such as religion and god (which are not defined rationally or scientifically in the extant literature cannot be rational. This paper offers a novel rational philosophical foundation for the concepts of god, religion and science in which the claim that science triumphs over religion is redundant. This paper also presents substantial new insights about epistemic truths to help resolve current problems facing humanity like financial moral hazard and terrorism which have unnerved nations worldwide. The humanity now begs to answer a fundamental question of how we can govern ourselves. This paper offers a coherent set of credible answers. In particular, it offers a coherent unified philosophy about how humans have universally formed beliefs to govern themselves and how this philosophy could help resolve current problems. The universal rendering of beliefs articulated here subsumes the extant characterization of probability beliefs in mathematics, science, engineering, economics, religion and philosophy. The universal beliefs so articulated in this paper obviate the currently prevalent philosophical conflicts between religion and science or between theism and atheism and paves the way for optimal governance for prosperity amid stability. This philosophy also offers a rational characterization of the spiritual notion of Nirvana or salvation of the soul and the notion of epistemic truth. The unifying philosophy can help humanity achieve unity, stability and prosperity, sans financial moral hazard, antagonism, wars, nuclear proliferation, global warming and atmospheric pollution.

    2012-01-01

    We present a unified model for the structure and appearance of accretion powered sources across their entire luminosity range from galactic X-ray binaries (XRB) to luminous quasars, with emphasis on AG N and their phenomenology. Central to this model is the notion of MHD winds launched by the accretion disks that power these objects. These winds provide the matter that manifests as blueshifted absorption features in the UV and X-ray spectra of a large fraction of these sources; furthermore, their density distribution in the poloidal plane determines their "appearance" (i.e. the column and velocity structure of these absorption features and the obscuration of the continuum source) as a function of the observer inclination angle (a feature to which INTEGRAL has made significant contributions). This work focuses on just the broadest characteristics of these objects; nonetheless, it provides scaling laws that allow one to reproduce within this model the properties of objects extending in luminosity from luminous quasars to XRBs. Our general conclusion is that the AGN phenomenology can be accounted for in terms of three parameters: The wind maSS flux in units of the Eddington value, m(dot), the observers' inclination angle Theta and the logarithmic slope between the 0/UV and X-ray fluxes alpha(sub ox); however because of a correlation between alpha(sub ox) and UV luminosity the number of significant parameters is two. The AGN correlations implied by this model appear to extend to and consistent with the XRB phenomenology, suggesting the presence of a truly unified underlying structure for accretion powered sources.

  4. Modeling smog along the Los Angeles-Palm Springs trajectory

    International Nuclear Information System (INIS)

    Hanna, S.R.

    1976-01-01

    Observations of smog concentrations and wind patterns during the summer of 1973 in Los Angeles, Pomona, Riverside, Banning, and Palm Springs, California are presented which show that high oxidant concentrations at Banning and Palm Springs are often due to advection of smog from source regions in the more densely populated western part of the Los Angeles basin. At Pomona and Riverside, advection from upwind source regions combines with the effects of local emissions to cause long durations of high oxidant concentrations with peak times in the mid afternoon. An empirical model for the diurnal oxidant variation is suggested which satisfactorily simulates observed concentrations. More complex models which include chemical kinetics systems do not perform very satisfactorily at the rural stations of Banning and Palm Springs, especially at night when observed oxidant concentrations remain high

    A unified nuclear reaction theory is a formalism for the scattering reactions of many-body nuclear systems which is capable of describing both direct interaction and compound nucleus formation processes. The Feshbach projection operator formalism is the original unified nuclear reaction theory. An alternative unified nuclear reaction theory called the X-matrix formalism is described. The X-matrix formalism is a generalization of the Brown-de Dominicis formalism. It does not require projection operators and is readly applied to rearrangement collisions

    A data model empowers us to store, retrieve and manipulate data in a unified way. We consider the biological data consists of DNA (De-Oxyribonucleic Acid), RNA (Ribonucleic Acid) and protein structures. In our Bioinformatics Lab (Bioinformatics Lab, Alkhawarizmi Institute of Computer Science, University of Engineering and Technology, Lahore, Pakistan), we have already proposed two data models for DNA and protein structures individually. In this paper, we propose a unified data model by using the data models of TOS (Temporal Object Oriented System) after making some necessary modifications to this data model and our already proposed the two data models. This proposed unified data model can be used for the modeling and maintaining the biological data (i.e. DNA, RNA and protein structures), in a single unified way. (author)

    We present a unified universal quantum cloning machine, which combines several different existing universal cloning machines together, including the asymmetric case. In this unified framework, the identical pure states are projected equally into each copy initially constituted by input and one half of the maximally entangled states. We show explicitly that the output states of those universal cloning machines are the same. One importance of this unified cloning machine is that the cloning procession is always the symmetric projection, which reduces dramatically the difficulties for implementation. Also, it is found that this unified cloning machine can be directly modified to the general asymmetric case. Besides the global fidelity and the single-copy fidelity, we also present all possible arbitrary-copy fidelities.

    Chatterjee, Avik; Gillman, Matthew W; Wong, Mitchell D

    2015-12-01

    To determine the relationship between household chaos and substance use, sexual activity, and violence-related risk behaviors in adolescents. We analyzed cross-sectional data among 929 high-school students in Los Angeles who completed a 90-minute interview that assessed health behaviors and household chaos with the 14-question Chaos, Hubbub, and Order Scale (CHAOS). Using the generalized estimating equation and adjusting for personal, parental, and family covariates, we examined associations of CHAOS score with substance use, sexual activity, and violent behavior outcome variables. We also examined the role of depression and school engagement as mediators. Mean (SD) age of the 929 students was 16.4 (1.3) years, 516 (55%) were female, and 780 (84%) were Latino. After adjustment, compared with students with CHAOS score 0, those students with the greatest scores (5-14) had ORs of 3.1 (95% CI 1.1-8.7) for smoking, 2.6 (95% CI 1.6-4.4) for drinking, 6.1 (95% CI 1.8-21) for substance use at school, and 1.9 (95% CI 1.1-3.3) for fighting in the past 12 months. Associations between CHAOS score and sexual risk and other violent behaviors were not significant. Depression and school engagement attenuated the associations. In this group of adolescents, greatest CHAOS score was associated with increased odds of risky health behaviors, with depression and school engagement as potential mediators. In the future, CHAOS score could be measured to assess risk for such behaviors or be a target for intervention to reduce chances of engaging in these behaviors. Copyright © 2015 Elsevier Inc.

  20. Understanding Global Change (UGC) as a Unifying Conceptual Framework for Teaching Ecology: Using UGC in a High School Biology Program to Integrate Earth Science and Biology, and to Demonstrate the Value of Modeling Global Systems in Promoting Conceptual Learning

    Science.gov (United States)

    Levine, J.; Bean, J. R.

    2017-12-01

    Global change science is ideal for NGSS-informed teaching, but presents a serious challenge to K-12 educators because it is complex and interdisciplinary- combining earth science, biology, chemistry, and physics. Global systems are themselves complex. Adding anthropogenic influences on those systems creates a formidable list of topics - greenhouse effect, climate change, nitrogen enrichment, introduced species, land-use change among them - which are often presented as a disconnected "laundry list" of "facts." This complexity, combined with public and mass-media scientific illiteracy, leaves global change science vulnerable to misrepresentation and politicization, creating additional challenges to teachers in public schools. Ample stand-alone, one-off, online resources, many of them excellent, are (to date) underutilized by teachers in the high school science course taken by most students: biology. The Understanding Global Change project (UGC) from the UC Berkeley Museum of Paleontology has created a conceptual framework that organizes, connects, and explains global systems, human and non-human drivers of change in those systems, and measurable changes in those systems. This organization and framework employ core ideas, crosscutting concepts, structure/function relationships, and system models in a unique format that facilitates authentic understanding, rather than memorization. This system serves as an organizing framework for the entire ecology unit of a forthcoming mainstream high school biology program. The UGC system model is introduced up front with its core informational graphic. The model is elaborated, step by step, by adding concepts and processes as they are introduced and explained in each chapter. The informational graphic is thus used in several ways: to organize material as it is presented, to summarize topics in each chapter and put them in perspective, and for review and critical thinking exercises that supplement the usual end-of-chapter lists of

  1. Giordano da Pisa and the language of angels

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available Among the issues about the angels considered by the Dominican preacher Giordano da Pisa, this essay studies the problem of their language. The question of the locutio angelica had become quite relevant in the scholastic thought from the XIIIth century and had been widely discussed by Thomas Aquinas and Giles of Rome; the study of this argument in Giordano da Pisa’s sermons shows the transition in the homiletic texts of a highly speculative theme and we can see how the preacher, who combines rather freely the positions of Thomas and Giles, filters the question for his lay public, simplifying the more difficult passages.

  3. Unified theory in the worldline approach

    Directory of Open Access Journals (Sweden)

    James P. Edwards

    2015-11-01

    Full Text Available We explore unified field theories based on the gauge groups SU(5 and SO(10 using the worldline approach for chiral fermions with a Wilson loop coupling to a background gauge field. Representing path ordering and chiral projection operators with functional integrals has previously reproduced the sum over the chiralities and representations of standard model particles in a compact way. This paper shows that for SU(5 the 5¯ and 10 representations – into which the Georgi–Glashow model places the left-handed fermionic content of the standard model – appear naturally and with the familiar chirality. We carry out the same analysis for flipped SU(5 and uncover a link to SO(10 unified theory. We pursue this by exploring the SO(10 theory in the same framework, the less established unified theory based on SU(6 and briefly consider the Pati–Salam model using SU(4×SU(2×SU(2.

    2007-01-01

    A new unified method which allocates transmission losses either to buses in a pool market or to individual transactions in a bilateral contract market is presented in this paper. A detailed derivation of the method is given. A bus-loss matrix and a transaction-loss matrix are developed to show the interactions between bus injections and transactions. It is further demonstrated that the ''Physical-power-flow-based'' method can be obtained as an approximation of this unified approach under certain simplifying assumptions. Test systems are used to illustrate how the proposed method behaves under different possible scenarios. (author)

    We show that there is a way to unify distribution functions that describe simultaneously a classical signal in space and (spatial) frequency and position and momentum for a quantum system. Probably the most well known of them is the Wigner distribution function. We show how to unify functions of the Cohen class, Rihaczek's complex energy function, and Husimi and Glauber-Sudarshan distribution functions. We do this by showing how they may be obtained from ordered forms of creation and annihilation operators and by obtaining them in terms of expectation values in different eigenbases.

  10. Letting Los Angeles Go: Lessons from Feral Landscapes

    Directory of Open Access Journals (Sweden)

    Joan Woodward

    2004-06-01

    Full Text Available Los Angeles is home to numerous feral landscapes: designed gardens no longer receiving intentional care. These are cultivated gardens, usually composed of plants from myriad global climate types, which have been abandoned or neglected and have adapted to native rainfall or unintentional water sources such as broken irrigation systems. They are found in canyons and ridges swept by fire, along rights-of-way where properties were condemned for freeways, in once-glorious neighbourhoods fallen on hard times, and in places where speculation places properties on hold. They are found in all regions and are particularly vivid in Los Angeles, proclaimed as "Lurch City" by Cuff (2000, where disruptive urban convulsions are frequent. These sites are rich with information pertinent to conceivable futures in which supplemental resources and care may not be reliable. This article portrays selected feral landscapes, briefly describes their responses to pervasive urban forces over time, and extracts design attributes to consider when creating future resilient landscapes. Scrutiny of these landscapes' decline and tenacity reveals a telling view of a region's volatility and global context and reminds us to take into account probable neglect when shaping future landscapes.

    2014-03-01

    Full Text Available Sea angels, Clione limacina and Paedoclione doliiformis, are small, floating sea slugs belonging to Gastropoda, and their gonads are a bright orange-red color. Sea angels feed exclusively on a small herbivorous sea snail, Limacina helicina. Carotenoids in C. limacina, P. doliiformis, and L. helicina were investigated for comparative biochemical points of view. β-Carotene, zeaxanthin, and diatoxanthin were found to be major carotenoids in L. helicina. L. helicina accumulated dietary algal carotenoids without modification. On the other hand, keto-carotenoids, such as pectenolone, 7,8-didehydroastaxanthin, and adonixanthin were identified as major carotenoids in the sea angels C. limacina and P. doliiformis. Sea angels oxidatively metabolize dietary carotenoids and accumulate them in their gonads. Carotenoids in the gonads of sea angels might protect against oxidative stress and enhance reproduction.

  5. Radial and Regge excitations in unified, grand unified and subconstituent models

    International Nuclear Information System (INIS)

    Schnitzer, H.J.

    1981-01-01

    Necessary group theoretic conditions for all elementary gauge bosons and fermions of an arbitrary renormalizable gauge theory to lie on Regge trajectories are reviewed. It is then argued that in properly unified gauge theories all particles of a given spin lie on Regge trajectories. This then implies that a properly unified gauge theory has no local U(1) factor groups, and no massive fermion singlets. A consideration of the general pattern of Regge and radial recurrences to be expected in quantum field theories suggests that the presence or absence of spin 3/2 quarks and/or leptons in the TeV region will provide crucial clues to enable one to distinguish between various classes of unified, grand unified, and subconstituent models. The correct interpretation of such excited fermions will require correlation with the higgs boson mass and possible radial and Regge excitations of the weak vector bosons. (orig.)

  9. The Demon-Angel method in systematic safety assessment

    International Nuclear Information System (INIS)

    Vassakis, A.G.

    1999-01-01

    Since 'design for safety' of large engineering systems with a high level of innovation requires an exhaustive safety analysis and since a subsequent corrective action may become a very large bottleneck in improving such a system, fundamental knowledge in designing safe systems is essential. The lack of any 'rule of thumb' makes such knowledge a matter of personal experience rather than the subject of an academic course. This paper proposes a new method for the theoretical safety study of different system configurations independently of any particular application. This method aims to help the construction of a 'rule of thumb' for what is a safe system and what is not. The Demon and Angel ideas are explained and the schematic presentation of these elements is introduced. Four representative case studies demonstrate the use of this method

  10. Sibling deidentification in the clinic: devil vs. angel.

    Science.gov (United States)

    Schachter, F F

    1985-09-01

    A four-member family structure consisting of two siblings contrasting in personality (sibling deidentification) and each identified with a different parent (split-parent identification) was recently reported (15). In well-functioning families, this tetrad or quadrangle is wide-spread in the first pair of siblings in the family and tends to be more common in same-sex pairs, suggesting that sibling deidentification is designed to mitigate the relatively intense sibling rivalry characteristic of these pairs and hence to maintain family harmony. In this collated case report, deidentification is found to follow the same pattern in 39 clinic first pairs. However, contrasting attributes are varied and nonevaluative in nonclinic pairs but mainly "good-bad" in clinic pairs, with polarization extreme. Results suggest that nonclinic siblings negotiate their identity (being) much as they negotiate about possessions (having) and that negotiations are blocked in clinic pairs, freezing mythic devil or angel identity. Intervention is directed at dislodging this block.

    Gargus, Gerald Vincent

    This investigation represents an in-depth understanding of teacher professional development at the Alexander Science Center School, a dependent charter museum school established through a partnership between the California Science Center and Los Angeles Unified School District. Three methods of data collection were used. A survey was distributed and collected from the school's teachers, resulting in a prioritized list of teacher professional development needs, as well as a summary of teachers' opinions about the school's existing professional development program. In addition, six key stakeholders in the school's professional development program were interviewed for the study. Finally, documents related to the school's professional development program were analyzed. Data collected from the interviews and documents were used to develop an understand various components of the Alexander Science Center School's professional development program. Teachers identified seven areas that had a high-priority for future professional development including developing skills far working with below-grade-level students, improving the analytical skills of student in mathematics, working with English Language Learners, improving students' overall reading ability levels, developing teachers' content-area knowledge for science, integrating science across the curriculum, and incorporating hands-on activity-based learning strategies to teach science. Professional development needs identified by Alexander Science Center School teachers were categorized based on their focus on content knowledge, pedagogical content knowledge, or curricular knowledge. Analysis of data collected through interviews and documents revealed that the Alexander Science Center School's professional development program consisted of six venues for providing professional development for teachers including weekly "banked time" sessions taking place within the standard school day, grade-level meetings, teacher support

  12. Climate Change and Adaptation Planning on the Los Angeles Aqueduct

    2009-12-01

    This study provides an assessment of the potential impacts of climate change on the Eastern Sierra Nevada snowpack and snowmelt timing, using a combination of empirical (i.e., data-based) models, and computer simulation models forced by GCM-projected 21st century climatology (IPCC 2007 AR4 projections). Precipitation from the Eastern Sierra Nevada is one of the main water sources for Los Angeles' more than 4 million people - a source whose future availability is critical to the city's growing population and large economy. Precipitation in the region falls mostly in winter and is stored in the large natural reservoir that is the snowpack. Meltwater from the Eastern Sierra is delivered to the city by the 340-mile long Los Angeles Aqueducts. The analysis is focused on the nature of the impact to the LAA water supplies over the 21st century due to potential climate change, including volume of precipitation, the mix of snowfall and rainfall, shifts in the timing of runoff, interannual variability and multi-year droughts. These impacts further affect the adequacy of seasonal and annual carryover water storage, and potentially water treatment. Most of the snow in the 10,000 km^2 Mono-Owens basins that feed the LAA occurs in a relatively narrow, 10-20 km wide, high-elevation band on the steep slopes of 20 smaller basins whose streams drain into the Owens River and thence LAA. Extending over 240 km in the north-south direction, these basins present special challenges for estimating snowpack amounts and downscaling climate-model data. In addition, there are few meteorological stations and snow measurements in the snow-producing parts of the basins to drive physically based hydrologic modeling.

  13. Immigrant incorporation in the garment industry of Los Angeles.

    Science.gov (United States)

    Light, I; Bernard, R B; Kim, R

    1999-01-01

    This study expands immigrant social network theory and examined employment patterns in the garment industry in Los Angeles, California, among Latino workers employed by Asian immigrant entrepreneurs. The study determined that a large percentage of immigrant employees found their jobs through the immigrant economy. Entrepreneurship increased the supply of local jobs and expanded the economy at destination at no expense to natives. Immigrant entrepreneurs bought firms from nonimmigrant owners or started new ones with an immigrant labor supply. Massey's index is flawed due to its exclusion of the role of entrepreneurs. Migration networks facilitate entrepreneurship, but some ethnic groups have fewer entrepreneurs, such as Mexicans and Central Americans. A 1993 Los Angeles survey identified 3642 garment factories in its county. Mean employment was 27.1 persons. The garment industry was the 4th largest industry in the area in 1996, with 98,700 employees. It represented 6% of all wage and salary employees in the City and 5.5% of the immigrant labor force in the County in 1990. 93% of garment workers in 1990 were immigrants. It is estimated that 51% of garment factory owners were Asians; most employees were Latinos. Census figures on sewing machine operators indicated 47.3% of owners were Whites and 42.45 were Asians. 53.3% of employees were other ethnic groups, 14.5% were Asians, and 32.2% were Whites. It is estimated that 47.2% of total employment was due to the immigration economy. 71.5% of the total employment in the garment industry was in the immigrant sector.

    2017-07-04

    An apparatus and method for extending the scalability and improving the partitionability of networks that contain all-to-all links for transporting packet traffic from a source endpoint to a destination endpoint with low per-endpoint (per-server) cost and a small number of hops. An all-to-all wiring in the baseline topology is decomposed into smaller all-to-all components in which each smaller all-to-all connection is replaced with star topology by using global switches. Stacking multiple copies of the star topology baseline network creates a multi-planed switching topology for transporting packet traffic. Point-to-point unified stacking method using global switch wiring methods connects multiple planes of a baseline topology by using the global switches to create a large network size with a low number of hops, i.e., low network latency. Grouped unified stacking method increases the scalability (network size) of a stacked topology.

  16. Finite Unified Theories and the Higgs boson

    CERN Document Server

    Heinemeyer, Sven; Zoupanos, George

    2012-01-01

    All-loop Finite Unified Theories (FUTs) are very interesting N = 1 supersymmetric Grand Unified Theories (GUTs) realising an old field theory dream, and moreover have a remarkable predictive power due to the required reduction of couplings. Based on this theoretical framework phenomenologically consistent FUTs have been constructed. Here we review two FUT models based on the SU(5) gauge group, which can be seen as special, restricted and thus very predictive versions of the MSSM. We show that from the requirement of correct prediction of quark masses and other experimental constraints a light Higgs-boson mass in the range M_h ~ 121 - 126 GeV is predicted, in striking agreement with recent experimental results from ATLAS and CMS. The model furthermore naturally predicts a relatively heavy spectrum with colored supersymmetric particles above ~ 1.5 TeV in agreement with the non-observation of those particles at the LHC.

  17. Can the laws of physics be unified ?

    CERN Document Server

    Langacker, Paul

    2017-01-01

    The standard model of particle physics describes our current understanding of nature's fundamental particles and their interactions, yet gaps remain. For example, it does not include a quantum theory of gravity, nor does it explain the existence of dark matter. Once complete, however, the standard model could provide a unified description of the very building blocks of the universe. Researchers have been chasing this dream for decades, and many wonder whether such a dream can ever be made a reality. Can the Laws of Physics Be Unified? is a short introduction to this exciting frontier of physics. The book is accessibly written for students and researchers across the sciences, and for scientifically minded general readers. Paul Langacker begins with an overview of the key breakthroughs that have shaped the standard model, and then describes the fundamental particles, their interactions, and their role in cosmology. He goes on to explain field theory, internal symmetries, Yang-Mills theories, strong and electro...

    Beginning with the expounding of Einstein understanding of advantages and disadvantages of general relativity theory, the authors proceed to consideration of what the complete unified theory have to be according to Einstein. The four theories which can be considered as ''unified'', namely weyl and Calutsa ones, worked out a half of century ago, and twistor twisting and supersymmetry theories, nowadays attracting attention, are briefly described and discussed. The authors come to a conclusion that achievements in elementary-particle physics have to affect any future theory, that this theory has to explain the principle contradictions between classical and quantum field theories, and that finally it can lead to change of the modern space-time model as a four-dimensional variety

    Alvarez, Jose L.; Quevedo, Hernando; Sanchez, Alberto

    2008-01-01

    In the space of thermodynamic equilibrium states we introduce a Legendre invariant metric which contains all the information about the thermodynamics of black holes. The curvature of this thermodynamic metric becomes singular at those points where, according to the analysis of the heat capacities, phase transitions occur. This result is valid for the Kerr-Newman black hole and all its special cases and, therefore, provides a unified description of black hole phase transitions in terms of curvature singularities.

    Neutrino mixing in a grand unified theory in which the neutrino mass matrix is determined by the Gell-Mann-Ramond-Slansky mechanism was investigated. With an arbitrary real right-handed Majorana mass matrix which incorporates three neutrino mass scales, the effects of the up-quark mass matrix are found to be dominant and as a result no significant mixing of ν/sub e/ occurs, while ν/sub μ/ - ν/sub γ/ mixing can be substantial

    In a unified theory of human reciprocity, the strong and weak forms are similar because neither is biologically altruistic and both require normative motivation to support cooperation. However, strong reciprocity is necessary to support cooperation in public goods games. It involves inflicting costs on defectors; and though the costs for punishers are recouped, recouping costs requires complex institutions that would not have emerged if weak reciprocity had been enough.

  7. Cosmic strings in unified gauge theories

    International Nuclear Information System (INIS)

    Everett, A.E.

    1981-01-01

    Some spontaneously broken gauge theories can give rise to stringlike vacuum structures (vortices). It has been pointed out by Vilenkin that in grand unified theories these can be sufficiently massive to have cosmological implications, e.g., in explaining the formation of galaxies. The circumstances in which such structures occur are examined. They do not occur in the simplest grand unified theories, but can occur in some more elaborate models which have been proposed. The cross section for the scattering of elementary particles by strings is estimated. This is used to evaluate the effect of collisions on the dynamics of a collapsing circular string, with particular attention to the question of whether energy dissipation by collision can reduce the rate of formation of black holes by collapsed strings, which may be unacceptably large in models where strings occur. It is found that the effect of collisions is not important in the case of grand unified strings, although it can be important for lighter strings

  8. Coset realization of unifying W-algebras

    International Nuclear Information System (INIS)

    Blumenhagen, R.; Huebel, R.

    1994-06-01

    We construct several quantum coset W-algebras, e.g. sl(2,R)/U(1) and sl(2,R)+sl(2,R)/sl(2,R), and argue that they are finitely nonfreely generated. Furthermore, we discuss in detail their role as unifying W-algebras of Casimir W-algebras. We show that it is possible to give coset realizations of various types of unifying W-algebras, e.g. the diagonal cosets based on the symplectic Lie algebras sp(2n) realize the unifying W-algebras which have previously been introduced as 'WD -n '. In addition, minimal models of WD -n are studied. The coset realizations provide a generalization of level-rank-duality of dual coset pairs. As further examples of finitely nonfreely generated quantum W-algebras we discuss orbifolding of W-algebras which on the quantum level has different properties than in the classical case. We demonstrate in some examples that the classical limit according to Bowcock and Watts of these nonfreely finitely generated quantum W-algebras probably yields infinitely nonfreely generated classical W-algebras.

  9. Unified strength theory and its applications

    CERN Document Server

    Yu, Mao-Hong

    2004-01-01

    This is a completely new theory dealing with the yield and failure of materials under multi-axial stresses. It provides a system of yield and failure criteria adopted for most materials, from metallic materials to rocks, concretes, soils, polymers etc. The Unified Strength Theory has been applied successfully to analyse the elastic limit, plastic limit capacities, the dynamic response behavior for some structures under static and moderate impulsive load, and may be implemented in some elasto-plastic finite element computer codes. The Unified Strength Theory is described in detail and by using this theory a series of results can be obtained. The Unified Strength Theory can improve the conservative Mohr-Coulomb Theory, and since intermediate principal stress is not taken into account in the Mohr-Coulomb theory and most experimental data is not pertainable to the Mohr-Coulomb Theory, a considerable economic benefit may be obtained. The book can also increase the effect of most commercial finite element computer ...

  10. Proton decay in grand unified theories

    International Nuclear Information System (INIS)

    Lucha, W.

    1984-01-01

    Interactions which violate the conservation of baryon and lepton number represent an intrinsic part of all grand unified theories (GUTs) of strong and electroweak interactions. These new interactions - predicted within the framework of GUTs - generate B and L violating four-fermion interactions via the exchange of superheavy particles which cannot be ascribed a well-defined baryon or lepton number. The effective coupling constant of these four-fermion interactions might be large enough to make the proton decay detectable by the present generation of experiments. In this review the basic concepts of conventional as well as supersymmetric GUTs relevant for proton decay are sketched. The baryon number violating sector of grand unified theories is discussed in more detail. Special emphasis is laid on the various selection rules arising as consequences of low-energy gauge invariance and supersymmetry for proton decay. These selection rules already determine the coarse pattern of the resulting decay modes and branching ratios without any reference to or detailed knowledge of the underlying grand unified theory. Finally the numerous theoretical predictions are summarized and confronted with experiment. (Author)

  11. The three constituencies of the state: why the state has lost unifying energy.

    We address resurgent populism by examining structural processes of state transformation in the UK, the US and France. Scholars stress the 'unifying energy of the state', a set of institutions and policies capable of limiting inequalities and defending legal regimes. One characteristic of modern Western statehood were packages of policies designed to integrate social groups and territories in part by ensuring common standards of provision and social citizenship across the nation state. This echoes James Scott's critical analysis of the modernist project of the state (1998). This 'unifying energy' had different origins including nationalist movements, combatting external influence or powers, war, and preparing citizens for the rigours of industrialization. Overcoming class differences and territorial differences (including cultural, social and economic differences) was a major source of mobilization to feed this 'unifying energy of the state' in France, Italy or Spain for instance. Political and cultural identities are related in significant part to respective nation states. We argue that this 'unifying energy' was an essential component of statehood in Europe and in the US. It is now largely lost. We explain why and the significance of its displacement. © London School of Economics and Political Science 2017.

    2018-02-12

    Observations of smog over the Los Angeles Basin (LAB) links high oxidant mixing ratios with poor visibility, sometimes smog by blimp in a Lagrangian-like format. The experiment on September 6, 1973, demonstrated that a blimp could travel with the wind across the LAB, observing ozone (O 3 ) and precursors, and particles of different size ranges. These included condensation nuclei (CN) concentrations dominated by particles of ≤ 0.1 µm diameter and light scattering coefficient (b sc ) representing mainly particles of 0.1-2.0 µm diameter. The results indicated a pollutant variation similar to that measured at a fixed site. Ozone was produced in an air mass, reaching a maximum of ~400 ppb in the presence of nitrogen oxides (NO x ) and nonmethane hydrocarbons (NMHCs), then declined. Although the photochemistry was developing, b sc grew with O 3 mixing ratio to a quasi-steady state at ~9-10 × 10 -4  m -1 , decreasing in value much later with decease in O 3 . The light scattering coefficient was found to be positively associated with the O 3 mixing ratio, whereas CN concentrations were negatively proportional to O 3 mixing ratio. The blimp experiment was supported with aircraft vertical profiles and ground-level observations from a mobile laboratory. The blimp flight obtained combined gas and particle changes aloft that could not be obtained by ground or fixed-wing aircraft measurements alone. The experiment was partially successful in achieving a true Lagrangian characterization of smog chemistry in a constrained or defined "open" air mass. The Los Angeles experiment demonstrated the use of a blimp as a platform for measurement of air pollution traveling with an air mass across an urban area. The method added unique data showing the relationship between photochemical smog chemistry and aerosol dynamics in smog. The method offers an alternative to reliance on smog chamber and modeling observations to designing air quality management strategies for reactive

    2016-12-01

    Full Text Available Rett syndrome is a neurodevelopmental genetic disorder and, because of some behavioral characteristics, individuals affected by the disease are known as silent angels. Girls with Rett syndrome perform stereotyped movements, they have learning difficulties, their reaction time is prolonged, and they seem alienated in the environment. These children require constant pediatric, neurological and orthopedic care. In the treatment of Rett syndrome physical therapy, music therapy, hydrotherapy, hippotherapy, behavioral methods, speech therapy and diet, are also used. In turn, psychological therapy of the syndrome is based on the sensory integration method, using two or more senses simultaneously. In 80% of cases, the syndrome is related to mutations of the MECP2 gene, located on chromosome X. The pathogenesis of Rett syndrome is caused by the occurrence of a non-functional MeCP2 protein, which is a transcription factor of many genes, i.e. Bdnf, mef2c, Sgk1, Uqcrc1. Abnormal expression of these genes reveals a characteristic disease phenotype. Clinical symptoms relate mainly to the nervous, respiratory, skeletal and gastrointestinal systems. Currently causal treatment is not possible. However, researchers are developing methods by which, perhaps in the near future, it will be possible to eliminate the mutations in the MECP2 gene, and this will give a chance to the patient for normal functioning.

  6. Evaluating Community Partnerships Addressing Community Resilience in Los Angeles, California

    2018-03-01

    Full Text Available Community resilience has grown in importance in national disaster response and recovery efforts. However, measurement of community resilience, particularly the content and quality of relationships aimed at improving resilience, is lacking. To address this gap, we used a social network survey to measure the number, type, and quality of relationships among organizations participating in 16 coalitions brought together to address community resilience in the Los Angeles Community Disaster Resilience project. These coalitions were randomized to one of two approaches (community resilience or preparedness. Resilience coalitions received training and support to develop these partnerships and implement new activities. Both coalition types received expert facilitation by a public health nurse or community educator. We also measured the activities each coalition engaged in and the extent to which partners participated in these activities at two time points. We found that the community resilience coalitions were initially larger and had lower trust among members than the preparedness communities. Over time, these trust differences dissipated. While both coalitions grew, the resilience community coalitions maintained their size difference throughout the project. We also found differences in the types of activities implemented by the resilience communities; these differences were directly related to the trainings provided. This information is useful to organizations seeking guidance on expanding the network of community-based organizations that participate in community resilience activities.

    Pincetl, Stephanie; Porse, Erik; Cheng, Deborah

    2016-08-01

    In the Los Angeles metropolitan region, nearly 100 public and private entities are formally involved in the management and distribution of potable water—a legacy rooted in fragmented urban growth in the area and late 19th century convictions about local control of services. Yet, while policy debates focus on new forms of infrastructure, restructured pricing mechanisms, and other technical fixes, the complex institutional architecture of the present system has received little attention. In this paper, we trace the development of this system, describe its interconnections and disjunctures, and demonstrate the invisibility of water infrastructure in LA in multiple ways—through mapping, statistical analysis, and historical texts. Perverse blessings of past water abundance led to a complex, but less than resilient, system with users accustomed to cheap, easily accessible water. We describe the lack of transparency and accountability in the current system, as well as its shortcomings in building needed new infrastructure and instituting new water rate structures. Adapting to increasing water scarcity and likely droughts must include addressing the architecture of water management.

    2012-01-01

    The Coastal Los Angeles Basin study unit is approximately 860 square miles and consists of the Santa Monica, Hollywood, West Coast, Central, and Orange County Coastal Plain groundwater basins (California Department of Water Resources, 2003). The basins are bounded in part by faults, including the Newport-Inglewood fault zone, and are filled with Holocene-, Pleistocene-, and Pliocene-age marine and alluvial sediments. The Central Basin and Orange County Coastal Plain are divided into a forebay zone on the northeast and a pressure zone in the center and southwest. The forebays consist of unconsolidated coarser sediment, and the pressure zones are characterized by lenses of coarser sediment divided into confined to semi-confined aquifers by lenses of finer sediments. The primary aquifer system in the study unit is defined as those parts of the aquifer system corresponding to the perforated intervals of wells listed in the California Department of Public Health (CDPH) database of public-supply wells. The majority of public-supply wells are drilled to depths of 510 to 1,145 feet, consist of solid casing from the land surface to a depth of about 300 to 510 feet, and are perforated below the solid casing. Water quality in the primary aquifer system may differ from that in the shallower and deeper parts of the aquifer systems.

  10. LEP constraints on grand unified theories

    International Nuclear Information System (INIS)

    Sarkar, Utpal

    1993-01-01

    Recent developments on grand unified theories (GUTs) in the context of the LEP measurements of the coupling constants are reviewed. The three coupling constants at the electroweak scale have been measured at LEP quite precisely. One can allow these couplings to evolve with energy following the renormalization group equations for the various groups and find out whether all the coupling constants meet at any energy. It was pointed out that the minimal SU(5) grand unified theory fails to satisfy this test. However, various extensions of the theory are still allowed. These extensions include (i) supersymmetric SU(5) GUT, with some arbitrariness in the susy breaking scale arising from the threshold corrections, (ii) non-susy SU(5) GUTs with additional fermions as well as Higgs multiplets, which has masses of the order of TeV, and (iii) non-renormalizable effect of gravity with a fine tuned relation among the coupling constants at the unification energy. The LEP results also constrain GUTs with an intermediate symmetry breaking scale. By adjusting the intermediate symmetry breaking scale, one usually can have unification, but these theories get constrained. For example, the left-right symmetric theories coming from GUTs can be broken only at energies higher than about ∼10 10 GeV. This implies that if right handed gauge bosons are found at energies lower than this scale, then that will rule out the possibility of grand unification. Another recent interesting development on the subject, namely, low energy unification, is discussed in this context. All the coupling constants are unified at energies of the order of ∼10 8 GeV when they are embedded in an SU(15)GUT, with some particular symmetry breaking pattern. But even in this case the results of the intermediate symmetry breaking scale remain unchanged. (author). 16 refs., 3 figs

    I present an argument, based on the topology of the universe, why there are three generations of fermions. The argument implies a preferred unified gauge group of SU(5), but with SO(10) representations of the fermions. The breaking pattern SU(5)→SU(3)xSU(2)xU(1) is preferred over the pattern SU(5)→SU(4)xU(1). On the basis of the argument one expects an asymmetry in the early universe microwave data, which might have been detected already

    Pechen, Alexander; Brif, Constantin; Wu, Rebing; Chakrabarti, Raj; Rabitz, Herschel

    2010-01-01

    Many proposals have been put forth for controlling quantum phenomena, including open-loop, adaptive feedback, and real-time feedback control. Each of these approaches has been viewed as operationally, and even physically, distinct from the others. This work shows that all such scenarios inherently share the same fundamental control features residing in the topology of the landscape relating the target physical observable to the applied controls. This unified foundation may provide a basis for development of hybrid control schemes that would combine the advantages of the existing approaches to achieve the best overall performance.

    Leading order gravitational corrections to the Einstein-Hilbert action can lead to a consistent picture of the universe by unifying the epochs of inflation and dark energy in a single framework. While the leading local correction induces an inflationary phase in the early universe, the leading...... nonlocal term leads to an accelerated expansion of the universe at the present epoch. We argue that both the leading UV and IR terms can be obtained within the framework of a covariant effective field theory of gravity. The perturbative gravitational corrections therefore provide a fundamental basis...

  20. A unified view of "how allostery works".

    Science.gov (United States)

    Tsai, Chung-Jung; Nussinov, Ruth

    2014-02-01

    The question of how allostery works was posed almost 50 years ago. Since then it has been the focus of much effort. This is for two reasons: first, the intellectual curiosity of basic science and the desire to understand fundamental phenomena, and second, its vast practical importance. Allostery is at play in all processes in the living cell, and increasingly in drug discovery. Many models have been successfully formulated, and are able to describe allostery even in the absence of a detailed structural mechanism. However, conceptual schemes designed to qualitatively explain allosteric mechanisms usually lack a quantitative mathematical model, and are unable to link its thermodynamic and structural foundations. This hampers insight into oncogenic mutations in cancer progression and biased agonists' actions. Here, we describe how allostery works from three different standpoints: thermodynamics, free energy landscape of population shift, and structure; all with exactly the same allosteric descriptors. This results in a unified view which not only clarifies the elusive allosteric mechanism but also provides structural grasp of agonist-mediated signaling pathways, and guides allosteric drug discovery. Of note, the unified view reasons that allosteric coupling (or communication) does not determine the allosteric efficacy; however, a communication channel is what makes potential binding sites allosteric.

    Spreadsheet software is often the tool of choice for ad-hoc tabular data management, processing, and visualization, especially on tiny data sets. On the other hand, relational database systems offer significant power, expressivity, and efficiency over spreadsheet software for data management, while lacking in the ease of use and ad-hoc analysis capabilities. We demonstrate DataSpread, a data exploration tool that holistically unifies databases and spreadsheets. It continues to offer a Microsoft Excel-based spreadsheet front-end, while in parallel managing all the data in a back-end database, specifically, PostgreSQL. DataSpread retains all the advantages of spreadsheets, including ease of use, ad-hoc analysis and visualization capabilities, and a schema-free nature, while also adding the advantages of traditional relational databases, such as scalability and the ability to use arbitrary SQL to import, filter, or join external or internal tables and have the results appear in the spreadsheet. DataSpread needs to reason about and reconcile differences in the notions of schema, addressing of cells and tuples, and the current "pane" (which exists in spreadsheets but not in traditional databases), and support data modifications at both the front-end and the back-end. Our demonstration will center on our first and early prototype of the DataSpread, and will give the attendees a sense for the enormous data exploration capabilities offered by unifying spreadsheets and databases.

  2. SO(10) supersymmetric grand unified theories

    Science.gov (United States)

    Dermisek, Radovan

    The origin of the fermion mass hierarchy is one of the most challenging problems in elementary particle physics. In the standard model fermion masses and mixing angles are free parameters. Supersymmetric grand unified theories provide a beautiful framework for physics beyond the standard model. In addition to gauge coupling unification these theories provide relations between quark and lepton masses within families, and with additional family symmetry the hierarchy between families can be generated. We present a predictive SO(10) supersymmetric grand unified model with D 3 x U(1) family symmetry. The hierarchy in fermion masses is generated by the family symmetry breaking D 3 x U(1) → ZN → nothing. This model fits the low energy data in the charged fermion sector quite well. We discuss the prediction of this model for the proton lifetime in light of recent SuperKamiokande results and present a clear picture of the allowed spectra of supersymmetric particles. Finally, the detailed discussion of the Yukawa coupling unification of the third generation particles is provided. We find a narrow region is consistent with t, b, tau Yukawa unification for mu > 0 (suggested by b → sgamma and the anomalous magnetic moment of the muon) with A0 ˜ -1.9m16, m10 ˜ 1.4m16, m16 ≳ 1200 GeV and mu, M1/2 ˜ 100--500 GeV. Demanding Yukawa unification thus makes definite predictions for Higgs and sparticle masses.

    The task of elucidating the mechanism of solubility enhancement using hydrotropes has been hampered by the wide variety of phase behaviour that hydrotropes can exhibit, encompassing near-ideal aqueous solution, self-association, micelle formation, and micro-emulsions. Instead of taking a field guide or encyclopedic approach to classify hydrotropes into different molecular classes, we take a rational approach aiming at constructing a unified theory of hydrotropy based upon the first principles of statistical thermodynamics. Achieving this aim can be facilitated by the two key concepts: (1) the Gibbs phase rule as the basis of classifying the hydrotropes in terms of the degrees of freedom and the number of variables to modulate the solvation free energy; (2) the Kirkwood-Buff integrals to quantify the interactions between the species and their relative contributions to the process of solubilization. We demonstrate that the application of the two key concepts can in principle be used to distinguish the different molecular scenarios at work under apparently similar solubility curves observed from experiments. In addition, a generalization of our previous approach to solutes beyond dilution reveals the unified mechanism of hydrotropy, driven by a strong solute-hydrotrope interaction which overcomes the apparent per-hydrotrope inefficiency due to hydrotrope self-clustering.

  4. A unified dynamics for micro and macrosystems

    An explicit model allowing a unified description of micro and macrosystems is exhibited. Firstly, a modified quantum dynamics for the description of macroobjects is constructed and it is shown that it forbids the occurrence of linear superpositions of states localized in far away spatial regions and induces an evolution agreeing with classical mechanics. This dynamics also allows a description of the evolution in terms of trajectories. To set up a unified description of all physical phenomena, a modification of the dynamics, with respect to the standard Hamiltonian one, is then postulated also for microscopic systems. It is shown that one can consistently deduce from it the previously considered dynamics for the centre of mass of macroscopic systems. Choosing in an appropriate way the parameters of the so obtained model one can show that the standard quantum theory for microobjects, the quantum mechanical wave packet reduction with fixed pointer positions, and the classical behaviour for macroobjects can be all derived in a consistent way. Moreover, in the case of a macroscopic system one can obtain, by means of appropriate approximations, a description of the evolution in terms of a phase-space density distribution obeying a Fokker-Planck diffusion equation.

    The results gathered here on simple Lie algebras have been selected with attention to the needs of unified model builders who study Yang-Mills theories based on simple, local-symmetry groups that contain as a subgroup the SUsup(w) 2 x Usup(w) 1 x SUsup(c) 3 symmetry of the standard theory of electromagnetic, weak, and strong interactions. The major topics include, after a brief review of the standard model and its unification into a simple group, the use of Dynkin diagrams to analyze the structure of the group generators and to keep track of the weights (quantum numbers) of the representation vectors; an analysis of the subgroup structure of simple groups, including explicit coordinatizations of the projections in weight space; lists of representations, tensor products and branching rules for a number of simple groups; and other details about groups and their representations that are often helpful for surveying unified models, including vector-coupling coefficient calculations. Tabulations of representations, tensor products, and branching rules for E 6 , SO 10 , SU 6 , F 4 , SO 9 , SO 5 , SO 8 , SO 7 , SU 4 , E 7 , E 8 , SU 8 , SO 14 , SO 18 , SO 22 , and for completeness, SU 3 are included. (These tables may have other applications.) Group-theoretical techniques for analyzing symmetry breaking are described in detail and many examples are reviewed, including explicit parameterizations of mass matrices. (orig.)

  6. A Unified Theoretical Framework for Cognitive Sequencing.

    The capacity to sequence information is central to human performance. Sequencing ability forms the foundation stone for higher order cognition related to language and goal-directed planning. Information related to the order of items, their timing, chunking and hierarchical organization are important aspects in sequencing. Past research on sequencing has emphasized two distinct and independent dichotomies: implicit vs. explicit and goal-directed vs. habits. We propose a theoretical framework unifying these two streams. Our proposal relies on brain's ability to implicitly extract statistical regularities from the stream of stimuli and with attentional engagement organizing sequences explicitly and hierarchically. Similarly, sequences that need to be assembled purposively to accomplish a goal require engagement of attentional processes. With repetition, these goal-directed plans become habits with concomitant disengagement of attention. Thus, attention and awareness play a crucial role in the implicit-to-explicit transition as well as in how goal-directed plans become automatic habits. Cortico-subcortical loops basal ganglia-frontal cortex and hippocampus-frontal cortex loops mediate the transition process. We show how the computational principles of model-free and model-based learning paradigms, along with a pivotal role for attention and awareness, offer a unifying framework for these two dichotomies. Based on this framework, we make testable predictions related to the potential influence of response-to-stimulus interval (RSI) on developing awareness in implicit learning tasks.

    2011-09-01

    The purpose of this work is to investigate Grand Unified Theories (GUTs) and to make the link with passed and upcoming experiments. The structure of this thesis is as follows. In the first chapter, we will briefly review the sequence of arguments leading to the Higgs mechanism, then to the different concepts underlying physics beyond the Standard Model, and to the paradigm of extra dimensional supersymmetric grand unified theories. At each level of the argumentation, we will mention the different solutions available. The second chapter introduces more formally supersymmetry and extra dimensions, focusing in particular on the aspects of symmetry breaking. Then, in the third chapter, we present in details the two frameworks of extra dimensional theories in which we worked, called supersymmetric gauge-Higgs unification (GHU) and holographic grand unification (HGU) as well as the developments and modifications we brought to them. The fourth chapter is devoted to the low energy viability of the GHU framework, as well as its phenomenological implications. The fifth chapter presents a more generic study of the property of GUT-scale degenerate Higgs mass matrix, common to both frameworks. Finally, the sixth chapter is devoted to the viability and phenomenological implications of the HGU framework, with special emphasis on lepton flavour violation. This quantitative study takes properly into account effects of matrix anarchy, as well as exact flavour observables. The results obtained should generalize, at least qualitatively, to any other model with similar localization and supersymmetry breaking features

    Full Text Available The Shield (FX 2002-08 and The Wire (HBO 2002-08 are two of the most ever critically acclaimed TV-shows and they both can be seen as the finest developed film noir proposals produced in television. The Wire transcends the cop-show genre by offering a multilayered portrait of the whole city of Baltimore: from police work to drug dealing, getting through stevedores’ union corruption, tricks of local politics, problems of the school system and some unethical journalism practices. On the other, The Shield offers a breathtaking cop-show that features in the foreground the moral ambiguity that characterizes the noir genre. Both series display complementary realist strategies (a neorealist aesthetic in The Wire; a cinéma vérité pastiche in The Shield that highlight the importance of city landscape in their narrative. Baltimore and Los Angeles are portrayed not only as a dangerous and ruined physical places, but are also intertwined with moral and political issues in contemporary cities, such as race, class, political corruption, social disintegration, economical disparities, the limitations of the system of justice, the failure of the American dream and so on. The complex and expanded narrative of The Wire and The Shield, as Dimemberg has written for film noir genre, “remains well attuned to the violently fragmented spaces and times of the late-modern world”. Therefore, this article will focus on how The Wire and The Shield (and some of their TV heirs, such as Southland and Justified reflect and renew several topics related to the city in the film noir tradition: the sociopolitical effects of showing the ruins of the centripetal industrial metropolis, the inferences of filming in actual places, the dramatic presence of what Augé coined as “no-places”, the bachelardian opposition between home and city, or the streets as an urban jungle where danger lurks in every corner.

  10. Molecular basis for Duarte and Los Angeles variant galactosemia

    Human erythrocytes that are homozygous for the Duarte enzyme variant of galactosemia (D/D) have a characteristic isoform on isoelectric focusing and 50% reduction in galactose-1-phosphate uridyltransferase (GALT) enzyme activity. The Duarte biochemical phenotype has a molecular genotype of N314D/N314D. The characteristic Duarte isoform is also associated with a variant called the {open_quotes}Los Angeles (LA) phenotype,{close_quotes} which has increased GALT enzyme activity. We evaluated GALT enzyme activity and screened the GALT genes of 145 patients with one or more N314D-containing alleles. We found seven with the LA biochemical phenotype, and all had a 1721C{r_arrow}T transition in exon 7 in cis with the N314D missense mutation. The 1721C{r_arrow}T transition is a neutral polymorphism for leucine at amino acid 218 (L218L). In pedigree analyses, this 1721C{r_arrow}T transition segregated with the LA phenotype of increased GALT activity in three different biochemical phenotypes (LA/N, LA/G, and LA/D). To determine the mechanism for increased activity of the LA variant, we compared GALT mRNA, protein abundance, and enzyme thermal stability in lymphoblast cell lines of D and LA phenotypes with comparable genotypes. GALT protein abundance was increased in LA compared to D alleles, but mRNA was similar among all genotypes. We conclude that the codon change N314D in cis with the base-pair transition 1721C{r_arrow}T produces the LA variant of galactosemia and that this nucleotide change increases GALT activity by increasing GALT protein abundance without increasing transcription or decreasing thermal lability. A favorable codon bias for the mutated codon with consequently increased translation rates is postulated as the mechanism. 23 refs., 3 figs., 4 tabs.

    This study, based on interviews with Mexican documented and undocumented women workers in Los Angeles county, finds that most of the women in both categories work in factories. Contrary to popular impression, only 10% of the undocumented women in this survey are engaged in private household employment, although 19% were so employed when they 1st came to the US. Despite this obvious change in occupation, in general occupational mobility from 1st jobs is insignificant. On the average, undocumented women's hourly rate of pay was 40 US cents higher than the minimum wage, and US$1.57 lower than the average documented women's wages. Within the same occupational category, the undocumented women earned less per hour. The smallest difference occured in the 'laborer's' category. Another departure from popular impression was that, 76% of undocumented workers were paid by check. The figure was 94% for documented women workers. The respondents who said they were paid in cash were most likely to be in the private household sector. 80% of the undocumented workers did not think that they were discriminated against in their jobs, suggesting that they are a rather timid group of workers who believe that they have no real options regarding their work life, and are relatively satisfied with what they have. Almost all the women said that they came to the US with the intention of staying permanently, or as long as they are not caught and sent back to Mexico, which is their biggest fear. Better job and better pay are the most important reasons given by most women for coming. Being temporarily laid off would not prompt them to return to Mexico, as they are confident that their chances of finding another minimum wage paying job are better in the US. A closek knit network of support usually tides them over during their period of joblessness.

    Real-time and integrated measurements of gaseous and particulate pollutants were conducted inside five conventional diesel school buses, a diesel bus with a particulate trap, and a bus powered by compressed natural gas (CNG) to determine the range of children's exposures during school bus commutes and conditions leading to high exposures. Measurements were made during 24 morning and afternoon commutes on two Los Angeles Unified School District bus routes from South to West Los Angeles, with seven additional runs on a rural/suburban route, and three runs to test the effect of window position. For these commutes, the mean concentrations of diesel vehicle-related pollutants ranged from 0.9 to 19 microg/m(3) for black carbon, 23 to 400 ng/m(3) for particle-bound polycyclic aromatic hydrocarbon (PB-PAH), and 64 to 220 microg/m(3) for NO(2). Concentrations of benzene and formaldehyde ranged from 0.1 to 11 microg/m(3) and 0.3 to 5 microg/m(3), respectively. The highest real-time concentrations of black carbon, PB-PAH and NO(2) inside the buses were 52 microg/m(3), 2000 ng/m(3), and 370 microg/m(3), respectively. These pollutants were significantly higher inside conventional diesel buses compared to the CNG bus, although formaldehyde concentrations were higher inside the CNG bus. Mean black carbon, PB-PAH, benzene and formaldehyde concentrations were higher when the windows were closed, compared with partially open, in part, due to intrusion of the bus's own exhaust into the bus cabin, as demonstrated through the use of a tracer gas added to each bus's exhaust. These same pollutants tended to be higher on urban routes compared to the rural/suburban route, and substantially higher inside the bus cabins compared to ambient measurements. Mean concentrations of pollutants with substantial secondary formation, such as PM(2.5), showed smaller differences between open and closed window conditions and between bus routes.

    Strains of Lactobacillus bulgaricus and Angel Yeast were combined to ferment raw pork and make pork jerky. After fermentation, the jerky was dried and then tested for sensory evaluation, pH and free amino acid content. The results showed that the optimal conditions for fermentation using L. bulgaricus and Angel Yeast were: a pH of 6.5, a 1:1 (v/v) ratio of L. bulgaricus to Angel Yeast, a fermentation time of 42 h and temperature of 25 °C. The results showed that the pork jerky fermented with the combined strains was not very sour which was close to the pH of 7.0 and had a higher free amino acid content which was more than 68.3 mg/100 g compared with the pork jerky fermented by either L. bulgaricus or Angel Yeast alone. Overall, the results demonstrate that fermentation of raw pork with combined strains of L. bulgaricus and Angel Yeast improves the quality and flavor of pork jerky.

    The purpose of the present study was to determine user satisfaction with Nanny Angel Network (nan), a free childcare service for mothers undergoing cancer treatment. All 243 living mothers who had used the nan service were invited by telephone to participate in an online research survey; 197 mothers (81%) consented to participate. The survey, sent by e-mail, consisted of 39 items divided into these categories: demographics, supports, use, satisfaction, and general comments. Of the 197 mothers who consented to receive the e-mailed survey, 104 (53%) completed it. More than 90% of the mothers were very satisfied with the help and support from their Nanny Angel. Many mothers mentioned that the Nanny Angel was most helpful during treatment and medical appointments, with 75% also mentioning that their Nanny Angel helped them to adhere to their scheduled medical appointments. However, 64% felt that they had not received enough visits from their Nanny Angel. Satisfaction with the nan childcare provider was high, but mothers wished the service had been available to them more often. Our study highlights the importance of providing childcare to mothers with inadequate support systems, so as to allow for greater adherence to treatment and medical appointments, and for more time to recover.

The Brazilian population is multiethnic, and the correct characterization of the Hb D is important, mainly because the method available for detection of abnormal hemoglobins, present a migration in the same zone at alkaline pH, for Hb S, D, and G for example. In this paper we studied a family with an abnormal hemoglobin like S in alkaline electrophoresis, by appropriated methods including HPLC and molecular analysis, characterized as hemoglobin D Los Angeles.As doenças hereditária da hemoglobina são as mais comuns doenças monogênicas e atualmente bem conhecidas do ponto de vista molecular, fato este que propiciou um avanço no seu controle e manuseio.

The inflaton can be a flat direction including right-handed sneutrino and the waterfall field is a GUT Higgs. The spectral index is ns = 0.96 which fits very well with recent data by PLANCK satellite. There is no both thermal and non-thermal gravitino problems. Non-thermal leptogenesis can be resulted from the decay of right-handed sneutrino which plays (part of) the role of inflaton.

    2002-01-01

    It is shown that embedding a four-dimensional flipped SU(5) model in a five-dimensional SO(10) model preserves the best features of both flipped SU(5) and SO(10). The missing partner mechanism, which naturally achieves both doublet-triplet splitting and suppression of d=5 proton decay operators, is realized as in flipped SU(5), while the gauge couplings are unified as in SO(10). The masses of down quarks and charged leptons, which are independent in flipped SU(5), are related by the SO(10). Distinctive patterns of quark and lepton masses can result. The gaugino mass M 1 is independent of M 3 and M 2 , which are predicted to be equal

    1976-01-01

    The problem of generally covariant extension of Lorentz invariant field equations, by means of covariant derivatives extracted from the nonsymmetric unified field, is considered. It is shown that the contracted curvature tensor can be expressed in terms of a covariant gauge derivative which contains the gauge derivative corresponding to minimal coupling, if the universal constant p, characterizing the nonsymmetric theory, is fixed in terms of Planck's constant and the elementary quantum of charge. By this choice the spinor representation of the linear connection becomes closely related to the spinor affinity used by Infeld and Van Der Waerden (Sitzungsber. Preuss. Akad. Wiss. Phys. Math. Kl.; 9:380 (1933)) in their generally covariant formulation of Dirac's equation. (author)

    Generation and disposal of wastes has been responsible for many economical, ecological and public health problems. In order to manage hazardous wastes in an environment friendly manner, many technical and administrative procedures should be implemented, including prevention, control of generation, and final disposal. A software named SUGERE - a unified system for waste management - is being developed. It is an easy to use tool that integrates all the steps involved in hazardous and radioactive waste management. This system is intended to help generators, transporters and owners of treatment, storage and disposal facilities to manage hazardous and radioactive wastes, by assuring compliance with environmental laws and consumer requirements. This paper presents the current status of the SUGERE software, developed using Borland Delphi package. The nuclear industry is used as a reference for developing this work. (author)

    2013-01-01

    A Unified Grand Tour of Theoretical Physics invites its readers to a guided exploration of the theoretical ideas that shape our contemporary understanding of the physical world at the fundamental level. Its central themes, comprising space-time geometry and the general relativistic account of gravity, quantum field theory and the gauge theories of fundamental forces, and statistical mechanics and the theory of phase transitions, are developed in explicit mathematical detail, with an emphasis on conceptual understanding. Straightforward treatments of the standard models of particle physics and cosmology are supplemented with introductory accounts of more speculative theories, including supersymmetry and string theory. This third edition of the Tour includes a new chapter on quantum gravity, focusing on the approach known as Loop Quantum Gravity, while new sections provide extended discussions of topics that have become prominent in recent years, such as the Higgs boson, massive neutrinos, cosmological perturba...

  5. A Unifying Theory of Biological Function.

    Science.gov (United States)

    van Hateren, J H

    2017-01-01

    A new theory that naturalizes biological function is explained and compared with earlier etiological and causal role theories. Etiological (or selected effects) theories explain functions from how they are caused over their evolutionary history. Causal role theories analyze how functional mechanisms serve the current capacities of their containing system. The new proposal unifies the key notions of both kinds of theories, but goes beyond them by explaining how functions in an organism can exist as factors with autonomous causal efficacy. The goal-directedness and normativity of functions exist in this strict sense as well. The theory depends on an internal physiological or neural process that mimics an organism's fitness, and modulates the organism's variability accordingly. The structure of the internal process can be subdivided into subprocesses that monitor specific functions in an organism. The theory matches well with each intuition on a previously published list of intuited ideas about biological functions, including intuitions that have posed difficulties for other theories.

    Systems, apparatuses, and methods for managing a unified shared virtual address space. A host may execute system software and manage a plurality of nodes coupled to the host. The host may send work tasks to the nodes, and for each node, the host may externally manage the node's view of the system's virtual address space. Each node may have a central processing unit (CPU) style memory management unit (MMU) with an internal translation lookaside buffer (TLB). In one embodiment, the host may be coupled to a given node via an input/output memory management unit (IOMMU) interface, where the IOMMU frontend interface shares the TLB with the given node's MMU. In another embodiment, the host may control the given node's view of virtual address space via memory-mapped control registers.

Section 1 contains some basic points concerning the structure of the standard strong and electroweak interactions prior to grand unification. A detailed expose of GUTs is attempted in sect. 2, including their basci principles and their consequences for particle physics. The minimal, simplest GUT, SU 5 is analysed in some detail and it will be used throughout these lectures as the GUT prototype. Finally, sect. 3 contains the most important cosmological implications of GUTs, including baryon number generation in the early Universe (in rather lengthy detail), dissipative processes in the very early Universe, grand unified monopoles, etc. (orig./HSI)

    Wali, K.C.

    1989-01-01

    This chapter presents an introduction into Grand Unified Theories. After a discussion of the general features to be expected in any such theory, and of the motivations for them, a detailed presentation of SU(5) theory is given. The group structures, particle multiplets, gauge and Higgs bosons are explained. The two stages of spontaneous symmetry breaking via the Higgs model, are calculated individually and in combination. Fermion mass matrices and relations between quark and lepton masses are derived. predictions of SU(5) theory, calculated using renormalization group methods, are derived. The chapter ends with discussions that bring together particle physics and cosmology, including the baryon asymmetry problem, phase transitions in the very early universe, and singularities like domain walls, vortex lines and monopoles.

  11. Supersymmetric grand unified theories and cosmology

    International Nuclear Information System (INIS)

    Lazarides, G.; Shafi, Q.

    1983-01-01

    By examining the behavior of supersymmetric grand unified theories (GUT's) in the very early universe we find two classes of realistic models. In one of them supersymmetry is broken at or near superheavy GUT scale. The cosmological implications of such models are expected to be similar to those of nonsupersymmetric GUT's. In the second class of models, the superheavy GUT scale is related to the supersymmetry-breaking scale in the manner of Witten. Two types of cosmological scenarios appear possible in this case, either with or without an intermediate (new) inflationary phase. They can be experimentally distinguished, since the former predicts an absence and the latter an observable number density of superheavy monopoles. A mechanism for generating baryon asymmetry in such models is pointed out

  12. A unified approach to the Darwin approximation

    International Nuclear Information System (INIS)

    Krause, Todd B.; Apte, A.; Morrison, P. J.

    2007-01-01

    There are two basic approaches to the Darwin approximation. The first involves solving the Maxwell equations in Coulomb gauge and then approximating the vector potential to remove retardation effects. The second approach approximates the Coulomb gauge equations themselves, then solves these exactly for the vector potential. There is no a priori reason that these should result in the same approximation. Here, the equivalence of these two approaches is investigated and a unified framework is provided in which to view the Darwin approximation. Darwin's original treatment is variational in nature, but subsequent applications of his ideas in the context of Vlasov's theory are not. We present here action principles for the Darwin approximation in the Vlasov context, and this serves as a consistency check on the use of the approximation in this setting

    An outline of the physical concepts evolution is given from the ancient philosophers to the present time. With qualitative explanations about the meaning of the theories that is the milestones of these concepts evolution, it mentions the ideas which lead the studies to the conception of a unified field theory. Chronologically, it has brief information about the ideas of Laplace (mechanical determinism), Maxwell (the field concept), Einsten (the space-time structure), Heisenberg and Schroedinger (the quantum mechanics), Dirac (the relativistic quantum and the antiparticles), Gell-Mann (the quarks), Weinberg-Salam (Weak interactions and eletromagnetic unification), H. Georgi and S. Glashon (strong interactions plus Weinberg-Salam), Kaluza-Klein (a fifth space-time coordinate), and Zumino-Weiss (supersymmetry and supergravity). (G.D.F.) [pt

  14. Preface to a GUT (Grand Unified Theory)

    International Nuclear Information System (INIS)

    Honig, W.

    1982-01-01

    A Grand Unified Theory (GUT) is proposed exhibiting relativistic invariance and based on a physical model for vacuum space consisting of the superposition of oppositely charged continuous fluids. Models for the photon, electron, neutrino, proton, etc., consist of separate unique variations in the relative densities of the fluids and their flow patterns. This GUT is also based on the use of transfinite axiomatic number forms and on a concept of metrical relativity which hopefully reconciles the many logical dichotomies in and between Special Relativity and Quantum Mechanics. These ideas result in a number of experimental proposals and predicted results which appear to be underivable from present paradigms, first among which is a physical model for the hidden variable of Quantum Mechanics. It is on these features that attention should rest. (Auth.)

  15. Higgsless grand unified theory breaking and trinification

    International Nuclear Information System (INIS)

    Carone, Christopher D.; Conroy, Justin M.

    2004-01-01

    Boundary conditions on an extra dimensional interval can be chosen to break bulk gauge symmetries and to reduce the rank of the gauge group. We consider this mechanism in models with gauge trinification. We determine the boundary conditions necessary to break the trinified gauge group directly down to that of the standard model. Working in an effective theory for the gauge-symmetry-breaking parameters on a boundary, we examine the limit in which the grand-unified theory-breaking-sector is Higgsless and show how one may obtain the low-energy particle content of the minimal supersymmetric standard model. We find that gauge unification is preserved in this scenario, and that the differential gauge coupling running is logarithmic above the scale of compactification. We compare the phenomenology of our model to that of four dimensional 'trinified' theories

  16. Grand unified models including extra Z bosons

    1989-01-01

    The grand unified theories (GUT) of the simple Lie groups including extra Z bosons are discussed. Under authors's hypothesis there are only SU 5+m SO 6+4n and E 6 groups. The general discussion of SU 5+m is given, then the SU 6 and SU 7 are considered. In SU 6 the 15+6 * +6 * fermion representations are used, which are not same as others in fermion content, Yukawa coupling and broken scales. A conception of clans of particles, which are not families, is suggested. These clans consist of extra Z bosons and the corresponding fermions of the scale. The all of fermions in the clans are down quarks except for the standard model which consists of Z bosons and 15 fermions, therefore, the spectrum of the hadrons which are composed of these down quarks are different from hadrons at present

    Systems, apparatuses, and methods for managing a unified shared virtual address space. A host may execute system software and manage a plurality of nodes coupled to the host. The host may send work tasks to the nodes, and for each node, the host may externally manage the node's view of the system's virtual address space. Each node may have a central processing unit (CPU) style memory management unit (MMU) with an internal translation lookaside buffer (TLB). In one embodiment, the host may be coupled to a given node via an input/output memory management unit (IOMMU) interface, where the IOMMU frontend interface shares the TLB with the given node's MMU. In another embodiment, the host may control the given node's view of virtual address space via memory-mapped control registers.

  19. A Unified Scaling Law in Spiral Galaxies.

    Science.gov (United States)

    Koda; Sofue; Wada

    2000-03-01

    We investigate the origin of a unified scaling relation in spiral galaxies. Observed spiral galaxies are spread on a plane in the three-dimensional logarithmic space of luminosity L, radius R, and rotation velocity V. The plane is expressed as L~&parl0;VR&parr0;alpha in the I passband, where alpha is a constant. On the plane, observed galaxies are distributed in an elongated region which looks like the shape of a surfboard. The well-known scaling relations L-V (Tully-Fisher [TF] relation), V-R (also the TF relation), and R-L (Freeman's law) can be understood as oblique projections of the surfboard-like plane into two-dimensional spaces. This unified interpretation of the known scaling relations should be a clue to understand the physical origin of all the relations consistently. Furthermore, this interpretation can also explain why previous studies could not find any correlation between TF residuals and radius. In order to clarify the origin of this plane, we simulate formation and evolution of spiral galaxies with the N-body/smoothed particle hydrodynamics method, including cooling, star formation, and stellar feedback. Initial conditions are set to 14 isolated spheres with two free parameters, such as mass and angular momentum. The cold dark matter (h=0.5, Omega0=1) cosmology is considered as a test case. The simulations provide the following two conclusions: (1) The slope of the plane is well reproduced but the zero point is not. This zero-point discrepancy could be solved in a low-density (Omega00.5) cosmology. (2) The surfboard-shaped plane can be explained by the control of galactic mass and angular momentum.

  20. An exploration of the gateway math and science course relationships in the Los Angeles Community College District

    Science.gov (United States)

    Buchanan, Donald G.

    This study evaluated selected demographic, pre-enrollment, and economic status variables in comparison to college-level performance factors of GPA and course completion ratios for gateway math and science courses. The Transfer and Retention of Urban Community College Students (TRUCCS) project team collected survey and enrollment data for this study in the Los Angeles Community College District (LACCD). The TRUCCS team surveyed over 5,000 students within the nine campus district beginning in the fall of 2000 and spring of 2001 with follow-up data for next several years. This study focused on the math and science courses; established background demographics; evaluated pre-enrollment high school self-reported grades; reviewed high school and college level math courses taken; investigated specific gateway courses of biology, chemistry and physics; and compared them to the overall GPAs and course completion ratios for 4,698 students. This involved the SPSS development of numerous statistical products including the data from frequency distributions, means, cross-tabulations, group statistics t-tests, independent samples t-tests, and one-way ANOVA. Findings revealed demographic and economic relationships of significance for students' performance factors of GPA and course completion ratios. Furthermore, findings revealed significant differences between the gender, age, ethnicity and economic employment relationships. Conclusions and implications for institutions of higher education were documented. Recommendations for dissemination, intervention programs, and future research were also discussed.

    2014-09-01

    Full Text Available This paper aims to introduce a developed reading of Roederer’s interpretation of pragmatic information as a good candidate for a Unifying Information Concept required for an as-yet-unavailable Science of Information. According to pragmatic information, information and information processing are exclusive attributes of biological systems related to the very definition of life. I will apply the notion to give new accounts in the following areas: (1 quantum interpretation: based on a modified version of David Bohm’s interpretation of quantum mechanics, I propose an ontological, information-based interpretation of quantum mechanics which, unlike Roederer’s interpretation, satisfies all conditions of pragmatic information; (2 artificial intelligence: the notion successfully distinguishes natural living systems from artifacts and natural non-living systems, providing a context to pose an information-based argument against the thesis of Strong Artificial Intelligence; (3 phenomenal consciousness: I will use pragmatic information to modify and update Chalmers’s Double-aspect Theory of Information to be explanatorily more powerful regarding the physical aspect of his theory; (4 causation: based on pragmatic information, I pose a new account of causation which differentiates causation in biology from causation in natural abiotic world.

  11. Unified creep-plasticity model for halite

    International Nuclear Information System (INIS)

    Krieg, R.D.

    1980-11-01

    There are two national energy programs which are considering caverns in geological salt (NaCl) as a storage repository. One is the disposal of nuclear wastes and the other is the storage of oil. Both short-time and long-time structural deformations and stresses must be predictable for these applications. At 300K, the nominal initial temperature for both applications, the salt is at 0.28 of the melting temperature and exhibits a significant time dependent behavior. A constitutive model has been developed which describes the behavior observed in an extensive set of triaxial creep tests. Analysis of these tests showed that a single deformation mechanism seems to be operative over the stress and temperature range of interest so that the secondary creep data can be represented by a power of the stress over the entire test range. This simple behavior allowed a new unified creep-plasticity model to be applied with some confidence. The resulting model recognizes no inherent difference between plastic and creep strains yet models the total inelastic strain reasonably well including primary and secondary creep and reverse loadings. A multiaxial formulation is applied with a back stress. A Bauschinger effect is exhibited as a consequence and is present regardless of the time scale over which the loading is applied. The model would be interpreted as kinematic hardening in the sense of classical plasticity. Comparisons are made between test data and model behavior

  12. Randomized central limit theorems: A unified theory.

    Science.gov (United States)

    Eliazar, Iddo; Klafter, Joseph

    2010-08-01

    The central limit theorems (CLTs) characterize the macroscopic statistical behavior of large ensembles of independent and identically distributed random variables. The CLTs assert that the universal probability laws governing ensembles' aggregate statistics are either Gaussian or Lévy, and that the universal probability laws governing ensembles' extreme statistics are Fréchet, Weibull, or Gumbel. The scaling schemes underlying the CLTs are deterministic-scaling all ensemble components by a common deterministic scale. However, there are "random environment" settings in which the underlying scaling schemes are stochastic-scaling the ensemble components by different random scales. Examples of such settings include Holtsmark's law for gravitational fields and the Stretched Exponential law for relaxation times. In this paper we establish a unified theory of randomized central limit theorems (RCLTs)-in which the deterministic CLT scaling schemes are replaced with stochastic scaling schemes-and present "randomized counterparts" to the classic CLTs. The RCLT scaling schemes are shown to be governed by Poisson processes with power-law statistics, and the RCLTs are shown to universally yield the Lévy, Fréchet, and Weibull probability laws.

  13. Argumentation and Inference: A Unified Approach

    Christophe Fouqueré

    2013-12-01

    Full Text Available We propose in this paper to use Ludics as a unified framework for the analysis of dialogue and the reasoning system. Not only is Ludics a logical theory, but it may also be built by means of concepts of game theory. We first present the main concepts of Ludics. A design is an abstraction and a generalization of the concept of proof. Interaction between designs is equivalent to cut elimination or modus ponens in logical theories. It appears to be a natural means for representing dialogues and also for reasoning. A design is a set of sequences of alternate actions, similar to a move in game theory. We apply Ludics to argumentative dialogues. We discuss how to model the speech acts of argumentative dialogues in terms of dialogue acts. A dialogue act is given by a Ludics action together with the expression that reveals the action in a turn of speech. We show also how arguments may be stored in a commitment state used for reasoning. Finally we revisit an example of juridical dialogue that has been analyzed by Prakken in a different framework.

  14. Unifying Theories of Psychedelic Drug Effects

    2018-03-01

    Full Text Available How do psychedelic drugs produce their characteristic range of acute effects in perception, emotion, cognition, and sense of self? How do these effects relate to the clinical efficacy of psychedelic-assisted therapies? Efforts to understand psychedelic phenomena date back more than a century in Western science. In this article I review theories of psychedelic drug effects and highlight key concepts which have endured over the last 125 years of psychedelic science. First, I describe the subjective phenomenology of acute psychedelic effects using the best available data. Next, I review late 19th-century and early 20th-century theories—model psychoses theory, filtration theory, and psychoanalytic theory—and highlight their shared features. I then briefly review recent findings on the neuropharmacology and neurophysiology of psychedelic drugs in humans. Finally, I describe recent theories of psychedelic drug effects which leverage 21st-century cognitive neuroscience frameworks—entropic brain theory, integrated information theory, and predictive processing—and point out key shared features that link back to earlier theories. I identify an abstract principle which cuts across many theories past and present: psychedelic drugs perturb universal brain processes that normally serve to constrain neural systems central to perception, emotion, cognition, and sense of self. I conclude that making an explicit effort to investigate the principles and mechanisms of psychedelic drug effects is a uniquely powerful way to iteratively develop and test unifying theories of brain function.

  15. Texture Repairing by Unified Low Rank Optimization

    2016-01-01

    In this paper, we show how to harness both low-rank and sparse structures in regular or near-regular textures for image completion. Our method is based on a unified formulation for both random and contiguous corruption. In addition to the low rank property of texture, the algorithm also uses the sparse assumption of the natural image: because the natural image is piecewise smooth, it is sparse in certain transformed domain (such as Fourier or wavelet transform). We combine low-rank and sparsity properties of the texture image together in the proposed algorithm. Our algorithm based on convex optimization can automatically and correctly repair the global structure of a corrupted texture, even without precise information about the regions to be completed. This algorithm integrates texture rectification and repairing into one optimization problem. Through extensive simulations, we show our method can complete and repair textures corrupted by errors with both random and contiguous supports better than existing low-rank matrix recovery methods. Our method demonstrates significant advantage over local patch based texture synthesis techniques in dealing with large corruption, non-uniform texture, and large perspective deformation.

    1990-01-01

    We evaluate some constraints on the construction of grand unified superstring theories (GUSTs) using higher level Kac-Moody algebras on the world-sheet. In the most general formulation of the heterotic string in four dimensions, an analysis of the basic GUST model-building constraints, including a realistic hidden gauge group, reveals that there are no E 6 models and any SO(10) models can only exist at level-5. Also, any such SU(5) models can exist only for levels 4≤k≤19. These SO(10) and SU(5) models risk having many large, massless, phenomenologically troublesome representations. We also show that with a suitable hidden sector gauge group, it is possible to avoid free light fractionally charged particles, which are endemic to string derived models. We list all such groups and their representations for the flipped SU(5)xU(1) model. We conclude that a sufficiently binding hidden sector gauge group becomes a basic model-building constraint.

  17. A Unified Model for Tidal Disruption Events

    Science.gov (United States)

    Dai, Lixin; McKinney, Jonathan C.; Roth, Nathaniel; Ramirez-Ruiz, Enrico; Miller, M. Coleman

    2018-06-01

    In the past few years wide-field optical and UV transient surveys and X-ray telescopes have allowed us to identify a few dozen candidate tidal disruption events (TDEs). While in theory the physical processes in TDEs are ubiquitous, a few distinct classes of TDEs have been observed. Some TDEs radiate mainly in NUV/optical, while others produce prominent X-rays. Moreover, relativistic jets have been observed in only a handful of TDEs. This diversity might be related to the details of the super-Eddington accretion and emission physics relevant to TDE disks. In this Letter, we utilize novel three-dimensional general relativistic radiation magnetohydrodynamics simulations to study the super-Eddington compact disk phase expected in TDEs. Consistent with previous studies, geometrically thick disks, wide-angle optically thick fast outflows, and relativistic jets are produced. The outflow density and velocity depend sensitively on the inclination angle, and hence so does the reprocessing of emission produced from the inner disk. We then use Monte Carlo radiative transfer to calculate the reprocessed spectra and find that that the observed ratio of optical to X-ray fluxes increases with increasing inclination angle. This naturally leads to a unified model for different classes of TDEs in which the spectral properties of the TDE depend mainly on the viewing angle of the observer with respect to the orientation of the disk.

  18. A unified grand tour of theoretical physics

    CERN Document Server

    Griffiths, J

    2002-01-01

    Anyone offering a grand tour is faced with several options. Should they concentrate on what may be considered to be essential features, or should they attempt to present a brief glimpse of almost everything? The present offering is a compromise between these two extremes. The area considered - theoretical physics - is now such a vast subject that some kind of compromise is essential. Indeed, the field is now so wide that few could even attempt to review it in a single-authored work. My task here is to assess how well this book has succeeded in its main aim of providing a unified (though introductory) tour of this subject. Constrained within a single volume, this is clearly not an updated Landau-Lifschitz. It cannot be expected to take any particular topic to the level of recent research. Nevertheless, it does seem to cover the broad range of essential topics which now constitute the subject. It starts (most appropriately in my opinion) with geometry. It then covers classical physics, general relativity and qu...

  15. PM 10 and ozone control strategy to improve visibility in the los angeles basin

    Science.gov (United States)

    Farber, Robert J.; Welsing, Peter R.; Rozzi, Carlo

    The greater Los Angeles metropolitan area is in violation of the United States Environmental Protection Agency (USEPA) ambient standards for both ozone and PM 10. Accompanying these violations are hazy summer conditions, with current annual median visibility in the inland portions of Los Angeles running about 13 km, and visibilities decreasing to about 3 km on the 90th percentile days (worst days). The USEPA has given the local air pollution control agency until 2010 to bring the area into compliance with these standards. Because of continued population growth, accompanying light industry, dependence on private motor vehicles, and adverse natural meteorological conditions, emission reductions costing billions of dollars will be needed between now and 2010. The combination of emission reductions which will result in the fastest ozone and PM 10 cleanup at the lowest cost are presented. Substantial emission reductions in NO x, reactive hydrocarbons, SO x, ammonia, soot and fugitive dust will result in visibility improvements in the Los Angeles area. However, enactment of this comprehensive control strategy will only improve the annual median visibility to about 20 km and the 90th percentile days to 6.5 km. Significant changes in fine mass will result in relatively small changes in perceived visibility since the human eye is unable to differentiate visual range changes even as large as 40% in an urban landscape typical of Los Angeles.

  6. Redox activity of airborne particulate matter at different sites in the Los Angeles Basin

    Cho, Arthur K.; Sioutas, Constantinos; Miguel, Antonio H.; Kumagai, Yoshito; Schmitz, Debra A.; Singh, Manisha; Eiguren-Fernandez, Arantza; Froines, John R.

    2005-01-01

    Epidemiologic studies have shown associations between ambient particulate matter (PM) and adverse health outcomes including increased mortality, emergency room visits, and time lost from school and work. The mechanisms of PM-related health effects are still incompletely understood, but a hypothesis under investigation is that many of the adverse health effects may derive from oxidative stress, initiated by the formation of reactive oxygen species (ROS) within affected cells. While the adverse effects from PM have historically been associated with the airborne concentration of PM and more recently fine-particle PM, we considered it relevant to develop an assay to quantitatively measure the ability of PM to catalyze ROS generation as the initial step in the induction of oxidative stress. This ability of PM could then be related to different sources, chemical composition, and physical and spatial/temporal characteristics in the ambient environment. The measurement of ROS-forming ability in relation to sources and other factors will have potential relevance to control of redox-active PM. If oxidative stress represents a relevant mechanism of toxicity from PM, the measurement of redox activity represents a first step in the elucidation of the subsequent downstream processes. We have developed an assay for PM redox activity, utilizing the reduction of oxygen by dithiothreitol which serves as an electron source. We have found that PM will catalyze the reduction of oxygen and have examined the distribution and chemical characteristics of the redox activity of PM fractions collected in different sites in the Los Angeles Basin. Samples of concentrated coarse, fine, and ultrafine PM, obtained with aerosol concentrators, were studied with regard to their chemical properties and redox activity. Redox activity was highest in the ultrafine fraction, in agreement with results indicating ultrafines were the most potent toward inducing that heme oxygenase expression and depleting

  9. Constructing 5d orbifold grand unified theories from heterotic strings

    International Nuclear Information System (INIS)

    Kobayashi, Tatsuo; Raby, Stuart; Zhang Renjie

    2004-01-01

    A three-generation Pati-Salam model is constructed by compactifying the heterotic string on a particular T 6 /Z 6 Abelian symmetric orbifold with two discrete Wilson lines. The compactified space is taken to be the Lie algebra lattice G 2 -bar SU(3)-bar SO(4). When one dimension of the SO(4) lattice is large compared to the string scale, this model reproduces many features of a 5d SO(10) grand unified theory compactified on an S 1 /Z 2 orbifold. (Of course, with two large extra dimensions we can obtain a 6d SO(10) grand unified theory.) We identify the orbifold parities and other ingredients of the orbifold grand unified theories in the string model. Our construction provides a UV completion of orbifold grand unified theories, and gives new insights into both field theoretical and string theoretical constructions

  10. On unified-entropy characterization of quantum channels

    International Nuclear Information System (INIS)

    Rastegin, A E

    2012-01-01

    We consider properties of quantum channels with the use of unified entropies. Extremal unravelings of quantum channel with respect to these entropies are examined. The concept of map entropy is extended in terms of the unified entropies. The map (q, s)-entropy is naturally defined as the unified (q, s)-entropy of a rescaled dynamical matrix of given quantum channel. Inequalities of Fannes type are obtained for introduced entropies in terms of both the trace and Frobenius norms of difference between corresponding dynamical matrices. Additivity properties of introduced map entropies are discussed. The known inequality of Lindblad with the entropy exchange is generalized to many of the unified entropies. For the tensor product of a pair of quantum channels, we derive a two-sided estimate on the output entropy of a maximally entangled input state. (paper)

    We introduce a new approach for studying unified supergravity models. In this approach all the parameters of the grand unified theory (GUT) are fixed by imposing the corresponding number of low energy observables. This determines the remaining particle spectrum whose dependence on the low energy observables can now be investigated. We also include some SUSY threshold corrections that have previously been neglected. In particular the SUSY threshold corrections to the fermion masses can have a significant impact on the Yukawa coupling unification. (orig.)

They are shown that, in particular, theories SU(5) as symmetry group, with 3 or more fermion families undergo dynamical symmetry breakdown, and some of the fermions will acquire mass at the Grand Unified scale. On the other hand, the SO(10) group, with 3 families is free from this problem. (Author) [pt

  18. ASSESSING ANGELS IN THE NURSERY: A PILOT STUDY OF CHILDHOOD MEMORIES OF BENEVOLENT CAREGIVING AS PROTECTIVE INFLUENCES.

    Science.gov (United States)

    Narayan, Angela J; Ippen, Chandra Ghosh; Harris, William W; Lieberman, Alicia F

    2017-07-01

    This pilot study provides the first empirical test of the concept of "Angels in the Nursery" by examining whether childhood memories of benevolent caregiving experiences protect against heightened levels of psychopathology in high-risk mothers. The study hypothesized that (a) elaborated childhood memories of feeling loved by a caregiver ("angel memories") would moderate adulthood posttraumatic stress disorder (PTSD) symptoms in mothers with childhood maltreatment histories, and (b) spontaneous traumatic intrusions ("ghost memories") would mediate childhood maltreatment and adulthood PTSD symptoms. Participants were 54 mothers (M = 32.79 years, SD = 8.91; 59.2% African American, 13.0% Caucasian, 5.6% Latina, 22.2% biracial/multiracial) who completed standardized assessments of childhood maltreatment and adulthood PTSD symptoms, and a novel instrument, the Angels in the Nursery Interview ("Angels Interview," Van Horn, Lieberman, & Harris, 2008). Results showed that angel memories significantly moderated childhood maltreatment and adulthood PTSD symptoms, consistent with a protective effect. Higher levels of ghost memories during the Angels Interview were significantly associated with more extensive childhood maltreatment, but did not mediate maltreatment and PTSD symptoms. Findings indicate that the Angels Interview can identify pathogenic intrusions rooted in childhood maltreatment and protective factors to promote maternal mental health and buffer the intergenerational transmission of trauma. © 2017 Michigan Association for Infant Mental Health.

  19. The Impact of Two Los Angeles County Teen Courts on Youth Recidivism: Comparing Two Informal Probation Programs

    Gase, Lauren N; Kuo, Tony; Lai, Elaine; Stoll, Michael A; Ponce, Ninez

    2016-01-01

    Objective This study sought to examine the impact of two Teen Courts operating in Los Angeles County, a juvenile justice system diversion program in which youth are judged by their peers and given restorative sentences to complete during a period of supervision. Methods A quasi-experimental design was used to compare youth who participated in Teen Court (n=112) to youth who participated in another diversion program administered by the Probation Department (the 654 Contract program) (n=194). Administrative data were abstracted from Probation records for all youth who participated in these programs between January 1, 2012 and June 20, 2014. Logistic and survival models were used to examine differences in recidivism - measured as whether the minor had any subsequent arrest or arrests for which the charge was filed. Results Comparison group participants had higher rates of recidivism than Teen Court participants, after controlling for age, gender, race/ethnicity, and risk level. While the magnitude of the program effects were fairly consistent across model specifications (odd ratios comparing Teen Court [referent] to school-based 654 Contract ranging from 1.95 to 3.07, hazard ratios ranging from 1.62 to 2.27), differences were not statistically significant in all scenarios. Conclusions While this study provides modest support for the positive impact of Teen Court, additional research is needed to better understand how juvenile diversion programs can improve youth outcomes.

  20. Lattice mechanics of ionic crystals - unified study

    International Nuclear Information System (INIS)

    Sengupta, S.; Roy, D.; Basu, A.N.

    1979-01-01

    The up-to-date situation in the understanding of the mechanical properties of ionic solids is reviewed. These properties are determined by the Born-Oppenheimer (B-O) potential energy function. For ionic crystals this potential energy function can be written down with some precision. To keep the expression tractable, the dominant electron deformation, the dipolar deformation, is treated as an adiabatic variable and the energy then becomes a function of both the nuclear coordinates and the ionic dipole moments. All the well known models for ionic crystals are discussed in terms of the energy expression they imply. This makes the comparison straight forward and brings out the essential difference between the models clearly. Next various quantum mechanical treatments for ionic crystals are reviewed. An attempt is made to obtain the B-O potential energy expression using a Heitler-London approach. By comparing the various models one can arrive at some definitive conclusions about the degree of validity and the assumptions underlying these models. Finally a comprehensive review of the results of actual computation on various ionic crystals done by different authors is undertaken. The crucial quantitative results are examined and the success and shortcoming of each calculation are critically analysed. The guiding principle in this part is the unified approach. i.e. to see how far a model with a given set of parameters accounts for both the dynamic and static properties. The discussion is divided in three sections for crystals with sodium chloride, cesium chloride and zinc sulfide structures. Outstanding problems and difficulties in the present understanding are pointed out. (auth.)

    While economic crises can increase socio-economic disparities in health, little is known about the impact of the 2008-09 Great Recession on obesity prevalence among children, especially low-income children. The present study examined whether socio-economic disparities in obesity among children of pre-school age participating in a federal nutrition assistance programme have changed since the recession. A pre-post observational study using administrative data of pre-school-aged programme participants from 2003 to 2014. Logistic regression was used to examine whether the relationship between obesity prevalence (BMI≥95th percentile of the Centers for Disease Control and Prevention's growth charts) and three measures of socio-economic status (household income, household educational attainment, neighbourhood-level median household income) changed after the recession by examining the interaction between each socio-economic status measure and a 5-year time-period variable (2003-07 v. 2010-14), stratified by child's age and adjusted for child's sociodemographic characteristics. Los Angeles County, California, USA. Children aged 2-4 years (n 1 637 788) participating in the Special Supplemental Nutrition Program for Women, Infants, and Children. The magnitude of the association of household income and household education with obesity increased after 2008-09 among 3- and 4-year-olds and 2- and 3-year-olds, respectively. However, the magnitude of the association of neighbourhood-level median household income with obesity did not change after 2008-09. Disparities in obesity by household-level socio-economic status widened after the recession, while disparities by neighbourhood-level socio-economic status remained the same. The widening household-level socio-economic disparities suggest that obesity prevention efforts should target the most vulnerable low-income children.

    Although health departments routinely inspect restaurants to assess compliance with established hygienic standards, few data are available on the effectiveness of these efforts in preventing foodborne disease. The study reported here assessed the impact on foodborne-disease hospitalizations in Los Angeles County of a restaurant hygiene grading system that utilized publicly posted grade cards. The grading systm was introduced in January 1998. Hospital discharge data on foodborne-disease hospitalizations were analyzed for Los Angeles County and, as a control, for the rest of California during the period 1993-2000. Ordinary least-squares regression analysis was done to measure the effect of the grading progam on these hospitalizations. After baseline temporal and geographic trends were adjusted for, the restaurant hygiene grading program was associated with a 13.1 percent decrease (p restaurant hygiene grading with public posting of results is an effective intervention for reducing the burden of foodborne disease.

  10. Seeking solace in West Hollywood: sexual orientation-based hate crimes in Los Angeles County.

    2010-01-01

    Many thriving "gay communities" across the United States report high levels of sexual orientation-based hate crimes every year, raising questions about the level of safety in these gay communities and neighborhoods. This study examines hate crime data from 2002-2006 in Los Angeles County and the relationship those hate crimes have to West Hollywood, the best known gay community of Los Angeles County. Results suggest that although West Hollywood does consistently report high numbers of hate crimes, this does not reflect a greatly increased risk to any one lesbian, gay, or bisexual person. Results suggest that we need to consider other variables as predictors (such as poverty, business density, and population density) in determining safe versus unsafe space, rather than just the percentage of lesbians, gay, and bisexuals in a population.

    "Using a unique 1994 Los Angeles County Household Survey of foreign-born Mexicans and the March 1994 and 1995 Current Population Surveys, we estimate the number of unauthorized Mexican immigrants (UMIs) residing in Los Angeles County, and compare their use of seven welfare programs with that of other non-U.S. citizens and U.S. citizens. Non-U.S. citizens were found to be no more likely than U.S. citizens to have used welfare, and UMIs were 11% (14%) less likely than other non-citizens (U.S.-born citizens).... We demonstrate how results differ depending on the unit of analysis employed, and on which programs constitute ¿welfare'." excerpt

    "By analysing how unauthorized Mexicans compare with seven other ethno-racial groups in Los Angeles County, separately and collectively, by educational attainment and time spent in the U.S., we find that unauthorized Mexicans had relatively fewer years of formal education (either in the U.S. or in Mexico) and had been in the U.S. a relatively fewer number of years than in-migrants of other ethno-racial backgrounds in 1990. These findings are then used as proxies to compare the human capital endowments of different ethno-racial groups. We next estimate the number of unauthorized Mexicans by occupation, industry and class of worker, and compare these distributions with the total labour force and with the other ethno-racial groups in Los Angeles County.... Results show that amounts of human capital are positively related to the kinds of occupations filled." (SUMMARY IN FRE AND SPA) excerpt

    2010-01-01

    The Los Angeles air basin is a significant anthropogenic source of greenhouse gasses and pollutants including CO2, CH4, N2O, and CO, contributing significantly to regional and global climate change. Recent legislation in California, the California Global Warning Solutions Act (AB32), established a statewide cap for greenhouse gas emissions for 2020 based on 1990 emissions. Verifying the effectiveness of regional greenhouse gas emissions controls requires high-precision, regional-scale measurement methods combined with models that capture the principal anthropogenic and biogenic sources and sinks. We present a novel approach for monitoring the spatial distribution of greenhouse gases in the Los Angeles basin using high resolution remote sensing spectroscopy. We participated in the CalNex 2010 campaign to provide greenhouse gas distributions for comparison between top-down and bottom-up emission estimates.

    Full Text Available This article argues that a certain type of Shanghai film of the Republican period, exemplified by 1937’s Street Angel (馬路天使, Malu tianshi, makes use of a specific mode of spatial organization, modelled on the theatre, to represent the urban environment. In the case of Street Angel, and later on in 1964’s Stage Sisters (舞台姐妹, Wutai jiemei, the interaction between performers and audiences characteristic of the Shanghai theatre experience serves as a crucial ground on which to base calls to political action. For a variety of related reasons, both the city of Shanghai and this mode of spatial organization so closely associated with it vanish from the big screen in the 1980s and 1990s, and begin to make a return only at the turn of the new century.

    The Los Angeles Data Resource (LADR) is a joint project of major Los Angeles health care provider organizations. The LADR helps clinical investigators to explore the size of potential research study cohorts using operational clinical data across all participating institutions. The Charles R. Drew University of Medicine and Science (CDU) LADR team sought to develop an innovative data architecture that would aggregate de-identified clinical data from safety-net providers in the community into CDU LADR node. This in turn would be federated with the other nodes of LADR for a shared view in a way that was never available before. This led to a self-service system to assess patients matching study criteria at each medical center and to search patients by demographics, ICD-9 codes, lab results and medications.

    The objective of this study was to examine whether an association exists between the number and type of food outlets in a neighborhood and dietary intake and body mass index (BMI) among adults in Los Angeles County. We also assessed whether this association depends on the geographic size of the food environment. We analyzed data from the 2011 Los Angeles County Health Survey. We created buffers (from 0.25 to 3.0 miles in radius) centered in respondents' residential addresses and counted the number of food outlets by type in each buffer. Dependent variables were weekly intake of fruits and vegetables, sugar-sweetened beverages, and fast food; BMI; and being overweight (BMI ≥25.0 kg/m(2)) or obese (BMI ≥30.0 kg/m(2)). Explanatory variables were the number of outlets classified as fast-food outlets, convenience stores, small food stores, grocery stores, and supermarkets. Regressions were estimated for all sets of explanatory variables and buffer size combinations (150 total effects). Only 2 of 150 effects were significant after being adjusted for multiple comparisons. The number of fast-food restaurants in nonwalkable areas (in a 3.0-mile radius) was positively associated with fast-food consumption, and the number of convenience stores in a walkable distance (in a 0.25-mile radius) was negatively associated with obesity. Little evidence was found for associations between proximity of respondents' homes to food outlets and dietary intake or BMI among adults in Los Angeles County. A possible explanation for the null finding is that shopping patterns are weakly related to neighborhoods in Los Angeles County because of motorized transportation.

  2. Nothing From Everything- A Unified Theory

    2016-07-01

    Nothing From Everything-A Unified Theory is a philosophical insight into principles of nature through principle of complementary spontaneity and principle of vertical continuity. This work is intended to explain various cosmological phenomena in light of behaviour of particles in range of their respective and relative speed of light. This theory explains creation of Universe from nothing or zero spacetime through scalar energy field collapsing into Higgs field resulting into giving mass to various particles. The energy particles taking origin from nothing while moving away from zero space-time would create space-time of their own order because energy/matter needs space to exist. The particles while moving away from zero space-time would end up in breaking symmetry of matter/energy at their mass infinity (highest possible mass of any particle, which is function of speed of spin). This break in symmetry would lead to curving of particles upon themselves and hence would lead to creation of antiparticles going back in time towards zero spacetime. Therefore the Universe could have been created by alternate layers of particles and antiparticles and also alternate layers of matter and antimatter with decelerating speed of light, which would lead to creation a closed and flat Universe. With increase in mass of Universe (creation of more and more Universe's matter from nothing), the gravitational force of Universe is bound to increase and hence with quantum by quantum increase in gravity, it would apply brakes on relative speed of photon/light out of its reference frame or designated space and hence speed of photon would decrease. If closed and flat Universe was created with decelerating speed of light, then such Universe is bound to contract back with accelerating speed of light which would have inverse impact on gravitational constant across various spacetime zones of Universe. And hence mass bodies would drift away spontaneously purely on basis and proportional to

  3. Angels as Mirrors of the Human: The Anthropologies of Rilke and Bonaventure through the Lenses of Hans Urs von Balthasar

    Yves De Maeseneer

    2016-07-01

    Full Text Available In this article we present a theological-anthropological exploration, interpreting the figure of the angel as a mirror of our human condition. The point of departure is an analysis of Hans Urs von Balthasar’s approach to two major sources of our imagination of the angel: Bonaventure (1221−1274 and Maria Rainer Rilke (1875−1926. A comparison of his accounts of the Franciscan theologian and the Modern poet, respectively, reveals remarkable parallels in discourse, clustered around the tensions between vulnerability and openness, immanence and transcendence, and love and loss. Both Rilke and Bonaventure reject the classical angel figure as a human ideal, as it cannot integrate the paradoxes of human existence. Their alternative visions of what it means to be human, have many terms in common: heart, vulnerability, mortality, openness, abyss, suspension, transparency, receptivity, descent (kenosis, humility, poverty, etc. However, their meaning is different because Rilke does not recognize an absolute transcendence as the source of love and the vis-a-vis of the human. This immanentism leaves him no other option than the vain attempt to exorcize the angel figure altogether, while Bonaventure’s vision preserves the angel as an anthropological mirror, albeit an angel radically transfigured by God’s wounded love.

  4. The undergraduate physics tutorial program at CSU Los Angeles assessment of utility and areas of interest

    Science.gov (United States)

    Avetyan, Smbat

    The Physics Education Research (PER) group at the University of Washington have researched traditional teaching methods and found that students in introductory physics are lacking a conceptual understanding of the physics material. The solution they put forth is an interactive tutorial program designed to meet the lack of conceptual understanding. Since the tutorial programs inception at CSU Los Angeles in Fall 2006 no evaluation has been successfully undertaken therefore the effect of the tutorial program in the physics 200 series is deeply obscure to the department. The research has shed light on the tutorial program and brought into context its effectiveness on the overall physics 200 series courses at CSU Los Angeles. The researcher has addressed the following research questions, what overall effect does the tutorial program have on the Physics 200 series curriculum? What is the size and significance of gains attributable to the undergraduate calculus based Physics 200 series tutorial program at CSU Los Angeles? What can we learn from gains about individual weekly lessons from the Physics 200 series tutorial courses? What is the correlation of tutorial gains with student final course grades? Are the gains from the tutorial program different for genders? Is there a difference in gains based on the different students' colleges?

    2008-11-01

    Full Text Available The objective of this study was to assess the relationship between alcohol availability, as measured by the density of off-premise alcohol outlets, and alcohol consumption in Los Angeles county and southern Louisiana, USA. Consumption information was collected through a telephone survey of 2,881 households in Los Angeles county and pre-Katrina southern Louisiana, nested within 220 census tracts. Respondents’ addresses were geo-coded and both neighbourhood (census tracts and buffers of varying sizes and individual (network distance to the closest alcohol outlet estimates of off-sale alcohol outlet density were computed. Alcohol outlet density was not associated with the percentage of people who were drinkers in either site. Alcohol outlet density was associated with the quantity of consumption among drinkers in Louisiana but not in Los Angeles. Outlet density within a one-mile buffer of the respondent’s home was more strongly associated with alcohol consumption than outlet density in the respondent’s census tract. The conclusion is that the relationship between neighbourhood alcohol outlet density and alcohol consumption is complex and may vary due to differences in neighbourhood design and travel patterns.

    After the devastating December 2004 Indian Ocean Tsunami, California and other coastal states began installing "Tsunami Warning Zone" and "Evacuation Route" signs at beaches and major access roads. The geography of the Los Angeles area may not be conducive to signage alone for communication of the tsunami risk and safety precautions. Over a year after installation, most people surveyed did not know about or recognize the tsunami signs. More alarming is that many did not believe a tsunami could occur in the area even though earthquake generated waves have reached nearby beaches as recently as September 2009! UPDATE: FEB. 2010. Fifty two percent of the 147 people surveyed did not believe they would survive a natural disaster in Los Angeles. Given the unique geography of Los Angeles, how can the city and county improve the mental health of its citizens before and after a natural disaster? This poster begins to address the issues of community self-efficacy and resiliency in the face of tsunamis. Of note for future research, the data from this survey showed that most people believed climate change would increase the occurrence of tsunamis. Also, the public understanding of water inundation was disturbingly low. As scientists, it is important to understand the big picture of our research - how it is ultimately communicated, understood, and used by the public.

  7. The Walking Renaissance: A Longitudinal Analysis of Walking Travel in the Greater Los Angeles Area, USA

    Directory of Open Access Journals (Sweden)

    Kenneth Joh

    2015-07-01

    Full Text Available Promoting walking travel is considered important for reducing automobile use and improving public health. Recent U.S. transportation policy has incentivized investments in alternative, more sustainable transportation modes such as walking, bicycling and transit in auto-oriented cities such as Los Angeles. Although many past studies have analyzed changes in walking travel across the U.S., there is little clarity on the drivers of change. We address this gap by conducting a longitudinal analysis of walking travel in the greater Los Angeles area from 2001 to 2009. We use travel diary and household data from regional and national surveys to analyze changes in walking trip shares and rates across our study area. Results show that walking has significantly increased across most of Los Angeles, and that increases in walking trips generally correspond with increases in population, employment, and transit service densities. Estimates from fixed-effects regression analysis generally suggest a positive association between population density and walking, and that higher increases in transit stop density are correlated with increased walking trips to and from transit stops. These findings illustrate how regional planning efforts to pursue a coordinated land use-transit planning strategy can help promote walking in auto-oriented or vehicle adopting cities.

  8. An Adaptive Unified Differential Evolution Algorithm for Global Optimization

    Energy Technology Data Exchange (ETDEWEB)

    Qiang, Ji; Mitchell, Chad

    2014-11-03

    In this paper, we propose a new adaptive unified differential evolution algorithm for single-objective global optimization. Instead of the multiple mutation strate- gies proposed in conventional differential evolution algorithms, this algorithm employs a single equation unifying multiple strategies into one expression. It has the virtue of mathematical simplicity and also provides users the flexibility for broader exploration of the space of mutation operators. By making all control parameters in the proposed algorithm self-adaptively evolve during the process of optimization, it frees the application users from the burden of choosing appro- priate control parameters and also improves the performance of the algorithm. In numerical tests using thirteen basic unimodal and multimodal functions, the proposed adaptive unified algorithm shows promising performance in compari- son to several conventional differential evolution algorithms.

    High-temperature superconductivity is closely adjacent to a long-range antiferromagnet, which is called a parent compound. In cuprates, all parent compounds are alike and carrier doping leads to superconductivity, so a unified phase diagram can be drawn. However, the properties of parent compounds for iron-based superconductors show significant diversity and both carrier and isovalent dopings can cause superconductivity, which casts doubt on the idea that there exists a unified phase diagram for them. Here we show that the ordered moments in a variety of iron pnictides are inversely proportional to the effective Curie constants of their nematic susceptibility. This unexpected scaling behavior suggests that the magnetic ground states of iron pnictides can be achieved by tuning the strength of nematic fluctuations. Therefore, a unified phase diagram can be established where superconductivity emerges from a hypothetical parent compound with a large ordered moment but weak nematic fluctuations, which suggests that iron-based superconductors are strongly correlated electron systems.

    1998-04-01

    One important current focus of modal identification is a reformulation of modal parameter estimation algorithms into a single, consistent mathematical formulation with a corresponding set of definitions and unifying concepts. Particularly, a matrix polynomial approach is used to unify the presentation with respect to current algorithms such as the least-squares complex exponential (LSCE), the polyreference time domain (PTD), Ibrahim time domain (ITD), eigensystem realization algorithm (ERA), rational fraction polynomial (RFP), polyreference frequency domain (PFD) and the complex mode indication function (CMIF) methods. Using this unified matrix polynomial approach (UMPA) allows a discussion of the similarities and differences of the commonly used methods. the use of least squares (LS), total least squares (TLS), double least squares (DLS) and singular value decomposition (SVD) methods is discussed in order to take advantage of redundant measurement data. Eigenvalue and SVD transformation methods are utilized to reduce the effective size of the resulting eigenvalue-eigenvector problem as well.

  15. Towards a Unified Sentiment Lexicon Based on Graphics Processing Units

    Directory of Open Access Journals (Sweden)

    Liliana Ibeth Barbosa-Santillán

    2014-01-01

    Full Text Available This paper presents an approach to create what we have called a Unified Sentiment Lexicon (USL. This approach aims at aligning, unifying, and expanding the set of sentiment lexicons which are available on the web in order to increase their robustness of coverage. One problem related to the task of the automatic unification of different scores of sentiment lexicons is that there are multiple lexical entries for which the classification of positive, negative, or neutral {P,N,Z} depends on the unit of measurement used in the annotation methodology of the source sentiment lexicon. Our USL approach computes the unified strength of polarity of each lexical entry based on the Pearson correlation coefficient which measures how correlated lexical entries are with a value between 1 and −1, where 1 indicates that the lexical entries are perfectly correlated, 0 indicates no correlation, and −1 means they are perfectly inversely correlated and so is the UnifiedMetrics procedure for CPU and GPU, respectively. Another problem is the high processing time required for computing all the lexical entries in the unification task. Thus, the USL approach computes a subset of lexical entries in each of the 1344 GPU cores and uses parallel processing in order to unify 155802 lexical entries. The results of the analysis conducted using the USL approach show that the USL has 95.430 lexical entries, out of which there are 35.201 considered to be positive, 22.029 negative, and 38.200 neutral. Finally, the runtime was 10 minutes for 95.430 lexical entries; this allows a reduction of the time computing for the UnifiedMetrics by 3 times.

    In this paper, the synchronization of a unified chaotic system is investigated by the use of output feedback controllers; a two-input single-output feedback controller and single-input single-output feedback controller are presented to synchronize the unified chaotic system when the states are not all measurable. Compared with the existing results, the controllers designed in this paper have some advantages such as small feedback gain, simple structure and less conservation. Finally, numerical simulations results are provided to demonstrate the validity and effectiveness of the proposed method

    1999-03-01

    In this paper, we propose a new nonlinear adaptive inverse control via a unified model neural network. In order to overcome nonsystematic design and long training time in nonlinear adaptive inverse control, we propose the approximate transformable technique to obtain a Chebyshev Polynomials Based Unified Model (CPBUM) neural network for the feedforward/recurrent neural networks. It turns out that the proposed method can use less training time to get an inverse model. Finally, we apply this proposed method to control magnetic bearing system. The experimental results show that the proposed nonlinear adaptive inverse control architecture provides a greater flexibility and better performance in controlling magnetic bearing systems.

    We discuss the importance of including baryons in analyses of unified dark matter scenarios, focusing on toy models involving a generalized Chaplygin gas. We determine observational constraints on this unified dark matter scenario coming from large-scale structure, type Ia supernovae and CMB data showing how this component can bring about a different behavior from the classical cold dark matter model with a cosmological constant and thus motivate further studies of this type of models. We also speculate on interesting new features which are likely to be important on nonlinear scales in this context

    International Nuclear Information System (INIS)

    Pestov, A.B.

    2012-01-01

    We put forward an idea that regularities of unified physics are in a simple relation: everything in the concept of space and the concept of space in everything. With this hypothesis as a ground, a conceptual structure of a unified geometrical theory of fundamental interactions is created and deductive derivation of its main equations is produced. The formulated theory gives solution of the actual problems, provides opportunity to understand the origin and nature of physical fields, local internal symmetry, time, energy, spin, charge, confinement, dark energy and dark matter, thus conforming the existence of new physics in its unity

  20. Transaction Costs: Valuation Disputes, Bi-Lateral Monopoly Bargaining and Third-Party Effects in Water Rights Exchanges. The Owens Valley Transfer to Los Angeles

    OpenAIRE

    2004-01-01

    Between 1905 and 1934 over 869 farmers in Owens Valley, California sold their land and associated water rights to Los Angeles, 250 miles to the southwest. This agriculture-to-urban water transfer increased Los Angeles' water supply by over 4 times, making the subsequent dramatic growth of the semi-arid city possible, generating large economic returns. The exchange took water from a marginal agricultural area and transferred it via the Los Angeles Aqueduct. No other sources of water became ava...

    Pulmonary embolism (PE) is a frequently occurring complication in critically ill patients, and the simultaneous occurrence of PE and life-threatening bleeding is a therapeutic dilemma. Inferior vena cava filters (IVCF) may represent an important therapeutic alternative in these cases. The Angel® catheter (Bio2 Medical Inc., San Antonio, TX, USA) is a novel IVCF that provides temporary protection from PE and is implanted at bedside without fluoroscopy. The European Angel® Catheter Registry is an observational, multicenter study. In our German substudy, we investigated patients from three German hospitals and four intensive care units, who underwent Angel® catheter implantation between February 2016 and December 2016. A total of 23 critically ill patients (68 ± 9 years, 43% male) were included. The main indication for implantation was a high risk for or an established PE, combined with contraindications for prophylactic or therapeutic anticoagulation due to either an increased risk of bleeding (81%) or active bleeding (13%). The Angel® catheter was successfully inserted in all patients at bedside. No PE occurred in patients with an indwelling Angel® catheter. Clots with a diameter larger the 20 mm, indicating clot migration, were detected in 5% of the patients by cavography before filter retrieval. Filter retrieval was uneventful in all of our cases, while filter dislocation occurred in 3% of the patients. The German data from the multicenter European Angel® Catheter Registry show that the Angel® catheter is a safe and effective approach for critically ill patients with a high risk for the development of PE or an established PE, when an anticoagulation therapy is contraindicated.

    This study aims to understand the associations of contraceptive service utilization (ie, accessing condoms or birth control), pregnancy attitudes, and lifetime pregnancy history among male and female homeless youth in relation to use of effective contraception and withdrawal. Between October 2011 and February 2012, homeless youth (14-27 years old) from 2 drop-in centers in Los Angeles (N = 380) were recruited and completed a questionnaire. The data in this paper are restricted to those who reported vaginal sex at last sex (N = 283). Analyses examined history of foster care, sexual abuse, exchange sex, pregnancy, lifetime homelessness duration, current living situation, contraceptive service utilization, and pregnancy attitudes in predicting use of effective contraception and withdrawal at last sex. Over 62% of females and 43% of males report having ever been pregnant or impregnating someone. There are no gender-based differences in pregnancy attitudes; 21% agree they would like to become pregnant within the year. Additionally, there are no gender-based differences in reported contraceptive use at last vaginal sex. In the multivariable model, high school education, contraceptive service utilization (Relative Risk Ratio [RRR]: 4.0), and anti-pregnancy attitudes (RRR: 1.3) are significant positive predictors of using effective contraception; anti-pregnancy attitudes (RRR: 1.2) and gender (RRR: 0.3) are significantly associated with using withdrawal. Health professionals should acknowledge that some homeless youth desire pregnancy; for those that do not, access to effective contraception is important. Programs must continue to promote pregnancy prevention, and include discussions of healthy pregnancy habits for pregnancy-desiring youth.

The most significant improvement was the establishment of extended precise leveling network of which is now able to connect all three major datum points at Pulau Lakei, Original and Bintulu. Datum by following the major accessible routes across Sarawak. This means the leveling network in Sarawak has now been inter-connected and unified. By having such a unified network leads to the possibility of having a common single least squares adjustment been performed for the first time. The least squares adjustment of this unified levelling network was attempted in order to compute the height of all Bench Marks established in the entire levelling network. The adjustment was done by using MoreFix levelling adjustment package developed at FGHT UTM. The computational procedure adopted is linear parametric adjustment by minimum constraint. Since Sarawak has three separate datums therefore three separate adjustments were implemented by utilizing datum at Pulau Lakei, Original Miri and Bintulu Datum respectively. Results of the MoreFix unified adjustment agreed very well with adjustment repeated using Starnet. Further the results were compared with solution given by Jupem and they are in good agreement as well. The difference in height analysed were within 10mm for the case of minimum constraint at Pulau Lakei datum and with much better agreement in the case of Original Miri Datum.

Observo que, embora originalmente articuladas a partir de Hollywood (Carmen Miranda nos limites da hierarquia entre as nações e do colonialismo, essas imagens são hoje alimentadas e recriadas também pelos próprios brasileiros. Uma das idéias centrais que defendo aqui é que embora tais imagens inicialmente restrinjam a ação das brasileiras, uma vez que sempre impõem o diálogo com os seus conteúdos, elas não o fazem permanentemente, ou seja, no processo de integração há espaço para a negociação de outras imagens e conteúdos e isto depende de fatores que vão além da exotização em si.This article discusses how middle and upper-middle class Brazilian women deal with their exoticized images in Los Angeles. It points out that although originally articulated from Hollywood (Carmen Miranda, within the limits of the hierarchy of nations and colonialism, today these images are also fed and recreated by Brazilians. One of the central ideas presented is that, despite constraining the movements and actions of the women, imposing on them the need to dialogue with their content, these exotic images do not do it permanently. In other words, in the process of integration, there is always room for negotiation of other images and contents that depend on factor other than exoticization itself.

  14. The Moon as a unifying sociological attraction

    Science.gov (United States)

    Barbieri, C.; Pachera, S.; Ciucci, A.

    We propose to develop an economic, fully automated telescope to equip a variety of public and private buildings, such as disco dancings, pubs, resting houses, hospitals, schools etc., optimized to image and project the Moon, both in daylight and nightime. We strongly believe that the wide spread conscience of being part of a common Universe, by imaging the real Moon ( not a series of computer files) and following its changing course, distributed in places where the soul is usually taken in a wave of loneliness, can have a profound effect. In fact, living such an experience of observation in places where people of all ages usually meet, can help them to mix up socially and have fun and acquire new interests and fulfillment. They could confront their doubts, opinions, curiosity. The Moon is the natural choice, being visible even in polluted cities, it comes to the Zenith of a large band on the Earth encompassing each emisphere, it has deeply rooted meanings in all civilizations, and it is therefore the perfect astronomical object towards which humanity should direct its view above the ground. The possibility of the instrument to zoom in and out and to move across the surface of the Moon or to observe in real time the slowly moving line of the terminator, is intended just for the sheer wonder of it. No didactic use is meant to begin with, although interest is sure to be stimulated and may be followed up in many ways. Our object is indeed to make young and older people throughout the world feel our satellite nearer and more familiar in the shapes and names of its features, truly a constant presence in our everyday natural surroundings. When the time will come for human coloniz ation, the Moon could no longer be considered such an extraneous, exotic and faraway new home. The telescope can be built in very large quantities by a variety of firms practically even in underdeveloped countries, easily automated and connected to the world wide web.

    Motor vehicles are the dominant source of oxides of nitrogen (NO{sub x}), particulate matter(PM), and certain air toxics (e.g., benzene, 1,3-butadiene) in urban areas. On roadways, motor vehicle-related pollutant concentrations are typically many times higher than ambient concentrations. Due to high air exchange rates typical of moving vehicles, this makes time spent in vehicles on roadways a major source of exposure. This paper presents on-road measurements for Los Angeles freeways and arterial roads taken from a zero-emission electric vehicle outfitted with real-time instruments. The objective was to characterize air pollutant concentrations on roadways and identify the factors associated with the highest concentrations. Our analysis demonstrated that on freeways, concentrations of ultrafine particles (UFPs), black carbon, nitric oxide, and PM-bound polycyclic aromatic hydrocarbons (PM-PAH) are generated primarily by diesel-powered vehicles, despite the relatively low fraction ({approx}6%) of diesel-powered vehicles on Los Angeles freeways. However, UFP concentrations on arterial roads appeared to be driven primarily by proximity to gasoline-powered vehicles undergoing hard accelerations. Concentrations were roughly one-third of those on freeways. By using a multiple regression model for the freeway measurements, we were able to explain 60-70% of the variability in concentrations of UFP, black carbon, nitric oxide, and PM-PAH using measures of diesel truck density and hour of day (as an indicator of wind speed). Freeway concentrations of these pollutants were also well correlated wth readily available annual average daily truck counts, potentially allowing improved population exposure estimates for epidemiology studies. Based on these roadway measurements and average driving time, it appears that 33-45% of total UFP exposure for Los Angeles residents occurs due to time spent traveling in vehicles. (author)

Due to high air exchange rates typical of moving vehicles, this makes time spent in vehicles on roadways a major source of exposure. This paper presents on-road measurements for Los Angeles freeways and arterial roads taken from a zero-emission electric vehicle outfitted with real-time instruments. The objective was to characterize air pollutant concentrations on roadways and identify the factors associated with the highest concentrations. Our analysis demonstrated that on freeways, concentrations of ultrafine particles (UFPs), black carbon, nitric oxide, and PM-bound polycyclic aromatic hydrocarbons (PM-PAH) are generated primarily by diesel-powered vehicles, despite the relatively low fraction (˜6%) of diesel-powered vehicles on Los Angeles freeways. However, UFP concentrations on arterial roads appeared to be driven primarily by proximity to gasoline-powered vehicles undergoing hard accelerations. Concentrations were roughly one-third of those on freeways. By using a multiple regression model for the freeway measurements, we were able to explain 60-70% of the variability in concentrations of UFP, black carbon, nitric oxide, and PM-PAH using measures of diesel truck density and hour of day (as an indicator of wind speed). Freeway concentrations of these pollutants were also well correlated with readily available annual average daily truck counts, potentially allowing improved population exposure estimates for epidemiology studies. Based on these roadway measurements and average driving time, it appears that 33-45% of total UFP exposure for Los Angeles residents occurs due to time spent traveling in vehicles.

    Full Text Available Oilfield-adjacent communities often report symptoms such as headaches and/or asthma. Yet, little data exists on health experiences and exposures in urban environments with oil and gas development. In partnership with Promotoras de Salud (community health workers, we gathered household surveys nearby two oil production sites in Los Angeles. We tested the capacity of low-cost sensors for localized exposure estimates. Bilingual surveys of 205 randomly sampled residences were collected within two 1500 ft. buffer areas (West Adams and University Park surrounding oil development sites. We used a one-sample proportion test, comparing overall rates from the California Health Interview Survey (CHIS of Service Planning Area 6 (SPA6 and Los Angeles County for variables of interest such as asthma. Field calibrated low-cost sensors recorded methane emissions. Physician diagnosed asthma rates were reported to be higher within both buffers than in SPA6 or LA County. Asthma prevalence in West Adams but not University Park was significantly higher than in Los Angeles County. Respondents with diagnosed asthma reported rates of emergency room visits in the previous 12 months similar to SPA6. 45% of respondents were unaware of oil development; 63% of residents would not know how to contact local regulatory authorities. Residents often seek information about their health and site-related activities. Low-cost sensors may be useful in highlighting differences between sites or recording larger emission events and can provide localized data alongside resident-reported symptoms. Regulatory officials should help clarify information to the community on methods for reporting health symptoms. Our community-based participatory research (CBPR partnership supports efforts to answer community questions as residents seek a safety buffer between sensitive land uses and active oil development.

    2015-01-01

    Simple Summary Low income has been reported to be a risk factor for dog relinquishment to shelters in the U.S. The majority of people with lower incomes, however, do not relinquish. Risk factors for relinquishment in a low socioeconomic region of Los Angeles were examined. Cost was associated with relinquishment, and most people were not aware of available assistance. Those who relinquished reported emotional attachment to the dog and higher perceived stress than a comparison group. The majority of reasons for relinquishment were likely solvable with assistance, highlighting an opportunity to provide community-specific alternatives to relinquishment. Abstract Dog relinquishment is a large component of shelter intake in the United States. Research has shown traits of the dog are associated with relinquishment as well as general characteristics of those relinquishing. Low income is often cited as a risk factor for relinquishment. The majority of people with lower incomes, however, do not relinquish. A group of people accessing a shelter in a low socioeconomic region of Los Angeles to relinquish their dogs was surveyed. This study examined risk factors for relinquishment, controlling for household income, compared to a group utilizing low cost spay/neuter services. A total of 76.9% of those relinquishing noted cost as a reason for relinquishment. Of participants in the relinquishment group, 80.7% reported not being aware of any services available to them. Most notable in the findings was that the odds of relinquishment were generally higher as the amount of perceived stress in the home in the past three months increased. The majority of people in both groups reported being emotionally attached to the dog. In this sample from a South Los Angeles community, the majority of reasons for relinquishment were likely solvable with assistance. These findings highlight an opportunity to assess community needs and provide community specific alternatives to relinquishment. PMID

  20. Perceptions of neighborhood safety and asthma among children and adolescents in Los Angeles: a multilevel analysis.

    Directory of Open Access Journals (Sweden)

    Marlene Camacho-Rivera

    Full Text Available Research examining the impact of neighborhoods on asthma has shown an increased interest in the role of the psychosocial environment. We examined the associations between various measures of neighborhood safety, individual and family characteristics, and asthma outcomes among children in Los Angeles.Multilevel logistic regression models were used to analyze data on 3,114 children across 65 neighborhoods from Wave 1 of the Los Angeles Family and Neighborhood Survey (2000 to 2002. Primary caregivers reported asthma outcome and all individual covariates; home environmental characteristics were observed by the interviewer.In fully adjusted models, parents who reported their neighborhood fairly safe or somewhat dangerous had lower odds of reported lifetime asthma compared to those who reported their neighborhood completely safe (OR 0.71; 95% CI 0.52-0.96 and OR 0.60; 95% CI 0.42-0.88 respectively. Conversely, parents who reported they could not trust their neighbors to keep their children safe had a nearly 40% increase in lifetime asthma compared to those who reported they could trust their neighbors to keep their children safe (OR 1.39; 95% CI 1.07-1.81.The study demonstrates a complex pattern between various measures of neighborhood safety and asthma and suggests that these relationships may operate differently in Los Angeles. As an increasing proportion of children are growing up in newer Western and Southwestern cities, which have different physical layouts and residential segregation patterns compared to Northeast and Midwestern cities, future studies should continue to examine neighborhood psychosocial stressors and asthma in diverse contexts.

    2001-01-01

    The U.S. Geological Survey conducted a detailed gravity study along part of the Los Angeles Regional Seismic Experiment (LARSE) transect across the San Fernando Basin and Transverse Ranges to help characterize the structure underlying this area. 249 gravity measurements were collected along the transect and to augment regional coverage near the profile. An isostatic gravity low of 50-60 mGal reflects the San Fernando-East Ventura basin. Another prominent isostatic gravity with an amplitude of 30 mGal marks the Antelope Valley basin. Gravity highs occur over the Santa Monica Mountains and the Transverse Ranges. The highest isostatic gravity values coincide with outcrops of Pelona schist.

  7. Comparison of two methods for estimating the number of undocumented Mexican adults in Los Angeles County.

    Science.gov (United States)

    Heer, D M; Passel, J F

    1987-01-01

    This article compares 2 different methods for estimating the number of undocumented Mexican adults in Los Angeles County. The 1st method, the survey-based method, uses a combination of 1980 census data and the results of a survey conducted in Los Angeles County in 1980 and 1981. A sample was selected from babies born in Los Angeles County who had a mother or father of Mexican origin. The survey included questions about the legal status of the baby's parents and certain other relatives. The resulting estimates of undocumented Mexican immigrants are for males aged 18-44 and females aged 18-39. The 2nd method, the residual method, involves comparison of census figures for aliens counted with estimates of legally-resident aliens developed principally with data from the Immigration and Naturalization Service (INS). For this study, estimates by age, sex, and period of entry were produced for persons born in Mexico and living in Los Angeles County. The results of this research indicate that it is possible to measure undocumented immigration with different techniques, yet obtain results that are similar. Both techniques presented here are limited in that they represent estimates of undocumented aliens based on the 1980 census. The number of additional undocumented aliens not counted remains a subject of conjecture. The fact that the proportions undocumented shown in the survey (228,700) are quite similar to the residual estimates (317,800) suggests that the number of undocumented aliens not counted in the census may not be an extremely large fraction of the undocumented population. The survey-based estimates have some significant advantages over the residual estimates. The survey provides tabulations of the undocumented population by characteristics other than the limited demographic information provided by the residual technique. On the other hand, the survey-based estimates require that a survey be conducted and, if national or regional estimates are called for, they may

    2015-01-30

    Carriers of the pork tapeworm, Taenia solium, are the sole source of cysticercosis, a parasitic tissue infection. When tapeworm eggs excreted by the carrier are ingested, tapeworm larvae can form cysts. When cysts form in the brain, the condition is called neurocysticercosis and can be especially severe. In Los Angeles County an average of 136 county residents are hospitalized with neurocysticercosis each year. The prevalence of Taenia solium carriage is largely unknown because carriage is asymptomatic, making detection difficult. The identification and treatment of tapeworm carriers is an important public health measure that can prevent additional neurocysticercosis cases.

  9. Comparison of nutrition standards and other recommended procurement practices for improving institutional food offerings in Los Angeles County, 2010-2012.

    2013-03-01

    National, state, and local institutions that procure, distribute, sell, and/or serve food to employees, students, and the public are increasingly capitalizing on existing operational infrastructures to create healthier food environments. Integration of healthy nutrition standards and other recommended practices [e.g., energy (kilocalories) postings at point-of-purchase, portion size restrictions, product placement guidelines, and signage] into new or renewing food service and vending contracts codifies an institution's commitment to increasing the availability of healthful food options in their food service venues and vending machines. These procurement requirements, in turn, have the potential to positively influence consumers' food-purchasing behaviors. Although these strategies are becoming increasingly popular, much remains unknown about their context, the processes required to implement them effectively, and the factors that facilitate their sustainability, especially in such broad and diverse settings as schools, county government facilities, and cities. To contribute to this gap in information, we reviewed and compared nutrition standards and other best practices implemented recently in a large school district, in a large county government, and across 10 municipalities in Los Angeles County. We report lessons learned from these efforts.

    Feldman, David L.

    2009-04-01

    Southern California's water history is an epic story with larger-than-life characters and ambitions and abundant hubris. Students of water policy might reasonably ask: Does this story, while unique to greater Los Angeles, hold lessons for other metropolises experiencing water conflict caused by explosive growth? We examine this question by considering similarities between the challenges facing Atlanta, Georgia, one of the nation's fastest growing cities in the 21st century, with those of Los Angeles. We focus on junctures where important decisions regarding water were made and how these decisions continue to challenge both cities' futures. Atlanta's financial, cultural, and environmental imprint on its surrounding region share remarkable similarities with Los Angeles' influence trajectory: it is the largest city in the southeast, a principal transportation and business hub, and it is embroiled in water conflict with nearby communities and adjoining states.

    An emerging model for sexuality education is the rights-based approach, which unifies discussions of sexuality, gender norms, and sexual rights to promote the healthy sexual development of adolescents. A rigorous evaluation of a rights-based intervention for a broad population of adolescents in the U.S. has not previously been published. This paper evaluates the immediate effects of the Sexuality Education Initiative (SEI) on hypothesized psychosocial determinants of sexual behavior. A cluster-randomized trial was conducted with ninth-grade students at 10 high schools in Los Angeles. Classrooms at each school were randomized to receive either a rights-based curriculum or basic sex education (control) curriculum. Surveys were completed by 1,750 students (N = 934 intervention, N = 816 control) at pretest and immediate posttest. Multilevel regression models examined the short-term effects of the intervention on nine psychosocial outcomes, which were hypothesized to be mediators of students' sexual behaviors. Compared with students who received the control curriculum, students receiving the rights-based curriculum demonstrated significantly greater knowledge about sexual health and sexual health services, more positive attitudes about sexual relationship rights, greater communication about sex and relationships with parents, and greater self-efficacy to manage risky situations at immediate posttest. There were no significant differences between the two groups for two outcomes, communication with sexual partners and intentions to use condoms. Participation in the rights-based classroom curriculum resulted in positive, statistically significant effects on seven of nine psychosocial outcomes, relative to a basic sex education curriculum. Longer-term effects on students' sexual behaviors will be tested in subsequent analyses. ClinicalTrials.gov NCT02009046.

    2017-01-01

    A geomorphological and pretrographic study was carried out at the lava flow Angeles and the Monte de la Cruz cone in the foothills of the Volcan Barva in Costa Rica. The 1967 aerial photographs at scale 1: 17,000 and 1: 13,000, 1992 at scale 1: 60,000 and TERRA 1997 at scale 1: 40,000 were used for the photogeological study, supplemented with the analysis of the eastern sector of the Hoja Topografica Barva (1: 50 000) of the Instituto Geografico Nacional (IGN) and other topographic maps at different scales (1: 25 000 and 1: 10 000), in addition to the digital elevation models developed through Sistemas de Informacion Geografica (SIG). The information extracted from the wells of the Sistema Nacional de Aguas Subterraneas, Riego y Avenamiento (SENARA) for underground control was reinterpreted. In the field work thicknesses were measured and an estimation of the volumes, dimensions of the cast and other associated geoforms was made. Likewise, 9 samples of rock were selected for the elaboration of thin sections and for their respective petrographic analysis, which allowed to define the main lava flow units and their possible flows. As a result of the volcanic activity of the cone, two flow units of the Angeles wash were identified, the Lower Angels unit and the Superior Angels unit. Petrographically, Angeles Inferior was reciprocated with an andesitic vesical basaltic lava with a porphyritic to slightly glomeroporphyric hypocrystalline texture, with plagioclase, clinopyroxene, orthopyroxene, olivine and opaque phenocrysts. On the other hand, Superior Angeles has been vesicular andesitic with a hypocrystalline texture, glomeroporfiritica to serial glomeroporfiritica, with plagioclase, clinopyroxene, orthopyroxene, olivine and opaque phenocrysts. Morphologically, kipukas and levees were observed. Regionally, it was observed that the Monte de la Cruz cone, along with other smaller satellite cones, are aligned N19 O W along 8.5 km, evidencing an origin associated with a

    The present state of meteorological and radiological measurement and monitoring are quite localized to smaller areas which implies the difficulties in knowing the measurement results in the wider region instantly. The need for establishing a distributed, flexible, modular and centralized measurement system for both meteorological and radiological parameters of environment is arising. The measurement and monitoring of radiological parameters of environment are not sufficient since there is a strong correlation between radiological and meteorological parameters which implies a unified distributed automatic monitoring system. The unified monitoring system makes it possible to transfer, process and store measured data in local and central databases. Central database gives a possibility of easy access to all measured data for authorized personnel and institutions. Stored measured data in central database gives a new opportunity to create a base for meteorological and radiological modelling and studies. (author)

    1997-01-01

    Three dominant themes of transcultural nursing as a global humanizer, diversifier, and unifier are discussed in relation to their meaning and uses in education, practice, research and consultation. The presenter takes the position that these three dominant themes are essential and imperative to promote, transform, and maintain desired care outcomes which are beneficial, satisfying, and healthy for people of diverse and similar cultures. The three themes are discussed within Leininger's theory of Culture Care Diversity and Universality with focus on the modes of action and decision-making. The author encourages transcultural nurses to take leadership to be an active global humanizer, diversifier, and unifier and transform nursing and health care into the 21st century.

    2015-01-01

    Anisotropic dark energy cosmological models are constructed in the frame work of generalised Brans-Dicke theory with a self-interacting potential. A unified dark fluid characterised by a linear equation of state is considered as the source of dark energy. The shear scalar is considered to be proportional to the expansion scalar simulating an anisotropic relationship among the directional expansion rates. The dynamics of the universe in the presence of a unified dark fluid in anisotropic background have been discussed. The presence of an evolving scalar field makes it possible to get an accelerating phase of expansion even for a linear relationship among the directional Hubble rates. It is found that the anisotropy in expansion rates does not affect the scalar field, the self-interacting potential, but it controls the non-evolving part of the Brans-Dicke parameter. (orig.)

    Full Text Available Standardized and sharing information platform is the foundation of the Smart Grids. In order to improve the dispatching center information integration of the power grids and achieve efficient data exchange, sharing and interoperability, a unified coding architecture is proposed. The architecture includes coding management layer, coding generation layer, information models layer and application system layer. Hierarchical design makes the whole coding architecture to adapt to different application environments, different interfaces, loosely coupled requirements, which can realize the integration model management function of the power grids. The life cycle and evaluation method of survival of unified coding architecture is proposed. It can ensure the stability and availability of the coding architecture. Finally, the development direction of coding technology of the Smart Grids in future is prospected.

    2011-01-01

    We consider the effects of a finite pedestal radial electric field on ion orbits using a unified approach. We then employ these modified orbit results to retain finite E x B drift departures from flux surfaces in an improved drift-kinetic equation. The procedure allows us to make a clear distinction between transit averages and flux surface averages when solving this kinetic equation. The technique outlined here is intended to clarify and unify recent evaluations of the banana regime decrease and plateau regime alterations in the ion heat diffusivity; the reduction and possible reversal of the poloidal flow in the banana regime, and its augmentation in the plateau regime; the increase in the bootstrap current; and the enhancement of the residual zonal flow regulation of turbulence.

    We discuss the onset of the nonlinear regime in the context of unified dark matter models involving a generalized Chaplygin gas. We show that the transition from dark-matter-like to dark-energy-like behavior will never be smooth. In some regions of space the transition will never take place while in others it may happen sooner or later than naively expected. As a result the linear theory used in previous studies may break down late in the matter dominated era even on large cosmological scales. We study the importance of this effect showing that its magnitude depends on the exact form of the equation of state in the low density regime. We expect that our results will be relevant for other unified dark matter scenarios, particularly those where the quartessence candidate is a perfect fluid

  6. High energy behaviour of particles and unified statistics

    International Nuclear Information System (INIS)

    Chang, Y.

    1984-01-01

    Theories and experiments suggest that particles at high energy appear to possess a new statistics unifying Bose-Einstein and Fermi-Dirac statistics via the GAMMA distribution. This hypothesis can be obtained from many models, and agrees quantitatively with scaling, the multiplicty, large transverse momentum, the mass spectrum, and other data. It may be applied to scatterings at high energy, and agrees with experiments and known QED's results. The Veneziano model and other theories have implied new statistics, such as, the B distribution and the Polya distribution. They revert to the GAMMA distribution at high energy. The possible inapplicability of Pauli's exclusion principle within the unified statistics is considered and associated to the quark constituents

    The method of reduction of couplings developed by W. Zimmermann, combined with supersymmetry, can lead to realistic quantum field theories, where the gauge and Yukawa sectors are related. It is the basis to find all-loop Finite Unified Theories, where the β-function vanishes to all-loops in perturbation theory. It can also be applied to the Minimal Supersymmetric Standard Model, leading to a drastic reduction in the number of parameters. Both Finite Unified Theories and the reduced MSSM lead to successful predictions for the masses of the third generation of quarks and the Higgs boson, and also predict a heavy supersymmetric spectrum, consistent with the non-observation of supersymmetry so far.

  8. Low-energy neutral current phenomenology and grand unified theories

    We derive necessary and sufficient conditions to be satisfied by any expanded electroweak gauge model in order to reproduce the standard model low-energy neutral current predictions. These conditions imply several constraints on the neutral gauge boson masses and the quantum number assignments for the ordinary fermions. Using these conditions, we prove that the popular grand unified theories based on the gauge groups SO(10) and E6 can only accommodate trivial extensions of the standard model. As a consequence, if any of these grand unified models works at some energy scale, present low-energy neutral current phenomenology implies that the Z-boson must be produced with the expected mass and couplings to the ordinary fermions. Any additional neutral gauge boson (with the possible exception of very heavy ones) could only be produced in hadronic collisions and it would not decay in e + e - . (orig.)

  9. Constructal Law and the Unifying Principle of Design

    Lorente, Sylvie; Bejan, Adrian

    2013-01-01

    Design happens everywhere, whether in animate objects (e.g., dendritic lung structures, bacterial colonies, and corals), inanimate patterns (river basins, beach slope, and dendritic crystals), social dynamics (pedestrian traffic flows), or engineered systems (heat dissipation in electronic circuitry). This “design in nature” often takes on remarkably similar patterns, which can be explained under one unifying Constructal Law. This book explores the unifying power of the Constructal Law and its applications in all domains of design generation and evolution, ranging from biology and geophysics to globalization, energy, sustainability, and security.  The Constructal Law accounts for the universal tendency of flow systems to morph into evolving configurations that provide greater and easier access over time. The Constructal Law resolves the many and contradictory ad hoc statements of “optimality”, end design, and destiny in nature, such as minimum and maximum entropy production and minimum and maximum fl...

  10. Unified Digital Periodic Signal Filters for Power Converter Systems

    Yang, Yongheng; Xin, Zhen; Zhou, Keliang

    2017-01-01

    Periodic signal controllers like repetitive and resonant controllers have demonstrated much potential in the control of power electronic converters, where periodic signals (e.g., ac voltages and currents) can be precisely regulated to follow references. Beyond the control of periodic signals, ac...... signal processing (e.g., in synchronization and pre-filtering) is also very important for power converter systems. Hence, this paper serves to unify digital periodic signal filters so as to maximize their roles in power converter systems (e.g., enhance the control of ac signals). The unified digital...... periodic signal filters behave like a comb filter, but it can also be configured to selectively filter out the harmonics of interest (e.g., the odd-order harmonics in single-phase power converter systems). Moreover, a virtual variable-sampling-frequency unit delay that enables frequency adaptive periodic...

    Full Text Available Authorization and its enforcement, access control, have stood at the beginning of the art and science of information security, and remain being crucial pillar of security in the information technology (IT and enterprises operations. Dozens of different models of access control have been proposed. Although Enterprise Architecture as the discipline strives to support the management of IT, support for modeling access policies in enterprises is often lacking, both in terms of supporting the variety of individual models of access control nowadays used, and in terms of providing a unified ontology capable of flexibly expressing access policies for all or the most of the models. This study summarizes a number of existing models of access control, proposes a unified metamodel mapped to ArchiMate, and illustrates its use on a selection of example scenarios and two business cases.

    Full Text Available The aim of the research is to identify some characters in the novel Where Angels Fear to Tread in teaching literary works. In learning of characters, someone will understand about the term of the interests, desires, emotions, and moral those form the individual within a story. Library research was used in thid study. The experts divide characters become two characters; they are central characters and additional characters. Central characters are a character who takes the greatest part in the main character or a figure that is most telling. Volume appearance of the main character more than the other characters. Meanwhile, additional characters or subordinate figures are figures that appear once or several times, figures that support or assist the central figure. In the novel Where Angels Fear To Tread, writer found some figures or characters such as: Mrs. Herriton, Lilia, Philip, Gino, and Carroline Abbot. Each of them had different characters; Mrs Herriton was a selfish and arrogant because she came from a high social status. Lilia was a patient and never denied what was ruled by her mother in-low although sometimes she was often treated her like slaves. Philip was figured as a handsome man, his tolerance and empathy were high. Gino was figured as stupid character. Miss Abbott as a nice, quiet, dull, and friendly.

  13. Origin of methane and sources of high concentrations in Los Angeles groundwater

    2018-01-01

    In 2014, samples from 37 monitoring wells at 17 locations, within or near oil fields, and one site >5 km from oil fields, in the Los Angeles Basin, California, were analyzed for dissolved hydrocarbon gas isotopes and abundances. The wells sample a variety of depths of an aquifer system composed of unconsolidated and semiconsolidated sediments under various conditions of confinement. Concentrations of methane in groundwater samples ranged from 0.002 to 150 mg/L—some of the highest concentrations reported in a densely populated urban area. The δ13C and δ2H of the methane ranged from −80.8 to −45.5 per mil (‰) and −249.8 to −134.9‰, respectively, and, along with oxidation‐reduction processes, helped to identify the origin of methane as microbial methanogenesis and CO2 reduction as its main formation pathway. The distribution of methane concentrations and isotopes is consistent with the high concentrations of methane in Los Angeles Basin groundwater originating from relatively shallow microbial production in anoxic or suboxic conditions. Source of the methane is the aquifer sediments rather than the upward migration or leakage of thermogenic methane associated with oil fields in the basin.

    Although violence against women is gaining international attention as a prevention priority, little is known about how risks differ across countries. A comparative study of violence against pregnant Mexican women in Morelos, Mexico, and Latina women in Los Angeles County, California, United States. In 1998 and 1999, women in prenatal clinics were interviewed about psychological abuse and sexual and physical violence by their partner, during and the 1 year prior to the index pregnancy. The overall response rate for Morelos was 99%, with a sample size of 914; Los Angeles County had a response rate of 96.9%, with a sample size of 219. Women in Morelos reported a higher prevalence of violence compared to women in the California (14.8% v 11.9%, respectively). A partner aged child were more than 25 times more likely to be abused during pregnancy than women not reporting this type of abuse. The identification of factors associated with violence against women, especially as they differ by culture and ethnicity, will help clinicians to better identify victims and to design and implement culturally appropriate prevention programs.

  15. Risk Factors for Dog Relinquishment to a Los Angeles Municipal Animal Shelter

    2015-12-01

    Full Text Available Dog relinquishment is a large component of shelter intake in the United States. Research has shown traits of the dog are associated with relinquishment as well as general characteristics of those relinquishing. Low income is often cited as a risk factor for relinquishment. The majority of people with lower incomes, however, do not relinquish. A group of people accessing a shelter in a low socioeconomic region of Los Angeles to relinquish their dogs was surveyed. This study examined risk factors for relinquishment, controlling for household income, compared to a group utilizing low cost spay/neuter services. A total of 76.9% of those relinquishing noted cost as a reason for relinquishment. Of participants in the relinquishment group, 80.7% reported not being aware of any services available to them. Most notable in the findings was that the odds of relinquishment were generally higher as the amount of perceived stress in the home in the past three months increased. The majority of people in both groups reported being emotionally attached to the dog. In this sample from a South Los Angeles community, the majority of reasons for relinquishment were likely solvable with assistance. These findings highlight an opportunity to assess community needs and provide community specific alternatives to relinquishment.

  16. Analysis of the Effects of ENSO and Atmospheric Rivers on Precipitation in Los Angeles County

    2017-12-01

    The Winter 2016-2017 season in California was marked by substantial amounts of precipitation; this resulted in critically-low reservoirs filling up and the removal of most of California from drought status. The year prior was characterized by one of the strongest El Nino-Southern Oscillation (ENSO) events, though it did not produce nearly enough precipitation as the 2016-2017 season. The major contributors to the increased rainfall during the 2016-2017 season were climactic phenomenon known as atmospheric rivers (ARs), which transport water vapor through the atmosphere in narrow bands, and are known to produce extreme rain events. Determining the exact timing, landfall areas, and total precipitation amounts of ARs is currently of great interest; a recent study showed that extreme weather events are likely to increase in California in the coming years, which motivates research into how phenomenon such as ENSO and ARs play a role. Using long-term daily rain gauge data provided by the Los Angeles County Department of Public Works, we compute the precipitation volume and storm count for various locations in Los Angeles County and identify anomalies. These data will then be compared with the occurrence and intensity of AR and ENSO events by using NOAA's NOI and ESRL AR data. The results can be used to provide a better grasp of extreme climactic patterns and their effects on the amount of precipitation in the region.

  17. The conundrum of police officer-involved homicides: Counter-data in Los Angeles County

    2016-08-01

    Full Text Available This paper draws from critical data studies and related fields to investigate police officer-involved homicide data for Los Angeles County. We frame police officer-involved homicide data as a rhetorical tool that can reify certain assumptions about the world and extend regimes of power. We highlight the possibility that this type of sensitive civic data can be investigated and employed within local communities through creative practice. Community involvement with data can create a countervailing force to powerful dominant narratives and supplement activist projects that hold local officials accountable for their actions. Our analysis examines four Los Angeles County police officer-involved homicide data sets. First, we provide accounts of the semantics, granularity, scale and transparency of this local data. Then, we describe a “counter data action,” an event that invited members of the community to identify the limits and challenges present in police officer-involved homicide data and to propose new methods for deriving meaning from these indicators and statistics.

    2016-11-16

    Due to the limited resolution at depth of geodetic and other geophysical data, the geometry and the loading rate of the ramp-décollement faults below the metropolitan Los Angeles are poorly understood. Here we complement these data by assuming conservation of motion across the Big Bend of the San Andreas Fault. Using a Bayesian approach, we constrain the geometry of the ramp-décollement system from the Mojave block to Los Angeles and propose a partitioning of the convergence with 25.5 ± 0.5 mm/yr and 3.1 ± 0.6 mm/yr of strike-slip motion along the San Andreas Fault and the Whittier Fault, with 2.7 ± 0.9 mm/yr and 2.5 ± 1.0 mm/yr of updip movement along the Sierra Madre and the Puente Hills thrusts. Incorporating conservation of motion in geodetic models of strain accumulation reduces the number of free parameters and constitutes a useful methodology to estimate the tectonic loading and seismic potential of buried fault networks.

    The Lagrangian-Hamiltonian unified formalism of R. Skinner and R. Rusk was originally stated for autonomous dynamical systems in classical mechanics. It has been generalized for non-autonomous first-order mechanical systems, first-order and higher-order field theories, and higher-order autonomous systems. In this work we present a generalization of this formalism for higher-order non-autonomous mechanical systems.

    If quarks and leptons are indeed elementary, it is natural that they belong to a single representation of a unifying group, G. It is shown that such a requirement, which is inconsistent with G = SU(N), can be satisfied within the semi-simple group G = SU(N) x SU(N). Furthermore, N = 7 emerges as the unique solution accompanied by a fermionic set that exhibits a natural generation structure

    Split octonion electrodynamics has been developed in terms of Zorn's vector matrix realization by reformulating electromagnetic potential, current, field tensor and other dynamical quantities. Corresponding field equation (Unified Maxwell's equations) and equation of motion have been reformulated by means of split octonion and its Zorn vector realization in unique, simpler and consistent manner. It has been shown that this theory reproduces the dyon field equations in the absence of gravito-dyons and vice versa

    A partial linearization method is proposed for realizing the chaos synchronization of an unified chaotic system. Through synchronizing partial state of the chaotic systems can result in the synchronization of their entire states, and the resulting controller is singularity free. The results can be easily extended to the synchronization of other similar chaotic systems. Simulation results are conducted to show the effectiveness of the method.

    We present a cosmologically acceptable grand unified model where the breaking of SU(5) proceeds through radiative corrections induced by supergravity soft-breaking terms. The breaking scale is determined by dimensional transmutation. The model is compatible with the radiative breaking of SU(2)sub(L)xU(1)sub(Y) which provides an experimentally accessible low energy particle spectrum and small top quark mass. (orig.)

    Spontaneously broken gauge theories may display distinct vortex string solutions for the disconnected components of the exact gauge symmetry group. A type of Higgs mechanism thought to apply in grand unified theories as being responsible for fermion masses yields Z 2 vortex lines, irrespectively of the group. These could seed galaxy formation if the corresponding fermion masses are superheavy. More generally a Higgs mechanism producing Zsub(n) vortex strings is presented. (orig.)

  16. Stratigraphic controls on saltwater intrusion in the Dominguez Gap area of coastal Los Angeles

    The Los Angeles Basin is a densely populated coastal area that significantly depends on groundwater. A part of this groundwater supply is at risk from saltwater intrusion-the impetus for this study. High-resolution seismic-reflection data collected from the Los Angeles-Long Beach Harbor Complex have been combined with borehole geophysical and descriptive geological data from four nearby ??400-m-deep continuously cored wells and with borehole geophysical data from adjacent water and oil wells to characterize the Pliocene to Holocene stratigraphy of the Dominguez Gap coastal aquifer system. The new data are shown as a north-south, two- dimensional, sequence-stratigraphic model that is compared to existing lithostratigraphic models of the Los Angeles Basin in an attempt to better understand pathways of saltwater intrusion into coastal aquifers. Intrusion of saltwater into the coastal aquifer system generally is attributed to over-pumping that caused the hydraulic gradient to reverse during the mid-1920s. Local water managers have used the existing lithostratigraphic model to site closely spaced injection wells of freshwater (barrier projects) attempting to hydraulically control the saltwater intrusion. Improved understanding of the stratigraphic relationships can guide modifications to barrier design that will allow more efficient operation. Allostratigraphic nomenclature is used to define a new sequence-stratigraphic model for the area because the existing lithostratigraphic correlations that have been used to define aquifer systems are shown not to be time-correlative. The youngest sequence, the Holocene Dominguez sequence, contains the Gaspur aquifer at its base. The Gaspur aquifer is intruded with saltwater and consists of essentially flat-lying gravelly sands deposited by the ancestral Los Angeles River as broad channels that occupied a paleovalley incised into the coastal plain during the last glacio-eustatic highstand. The underlying sequences are deformed into

  17. Unified Stochastic Geometry Model for MIMO Cellular Networks with Retransmissions

    KAUST Repository

    Afify, Laila H.

    2016-10-11

    This paper presents a unified mathematical paradigm, based on stochastic geometry, for downlink cellular networks with multiple-input-multiple-output (MIMO) base stations (BSs). The developed paradigm accounts for signal retransmission upon decoding errors, in which the temporal correlation among the signal-to-interference-plus-noise-ratio (SINR) of the original and retransmitted signals is captured. In addition to modeling the effect of retransmission on the network performance, the developed mathematical model presents twofold analysis unification for MIMO cellular networks literature. First, it integrates the tangible decoding error probability and the abstracted (i.e., modulation scheme and receiver type agnostic) outage probability analysis, which are largely disjoint in the literature. Second, it unifies the analysis for different MIMO configurations. The unified MIMO analysis is achieved by abstracting unnecessary information conveyed within the interfering signals by Gaussian signaling approximation along with an equivalent SISO representation for the per-data stream SINR in MIMO cellular networks. We show that the proposed unification simplifies the analysis without sacrificing the model accuracy. To this end, we discuss the diversity-multiplexing tradeoff imposed by different MIMO schemes and shed light on the diversity loss due to the temporal correlation among the SINRs of the original and retransmitted signals. Finally, several design insights are highlighted.

  18. The performance of FLake in the Met Office Unified Model

    Directory of Open Access Journals (Sweden)

    Gabriel Gerard Rooney

    2013-12-01

    Full Text Available We present results from the coupling of FLake to the Met Office Unified Model (MetUM. The coupling and initialisation are first described, and the results of testing the coupled model in local and global model configurations are presented. These show that FLake has a small statistical impact on screen temperature, but has the potential to modify the weather in the vicinity of areas of significant inland water. Examination of FLake lake ice has revealed that the behaviour of lakes in the coupled model is unrealistic in some areas of significant sub-grid orography. Tests of various modifications to ameliorate this behaviour are presented. The results indicate which of the possible model changes best improve the annual cycle of lake ice. As FLake has been developed and tuned entirely outside the Unified Model system, these results can be interpreted as a useful objective measure of the performance of the Unified Model in terms of its near-surface characteristics.

    Full Text Available Introduction: The use of unified power quality conditioners UPQC in the electric systems can correct waveform distortions in a steady state, like harmonics, flicker, and the power factor. Objective: This paper presents a novel approach for active compensation of overvoltage with a UPQC in dual topology or iUPQC. Methodology: The study it is presented in five stages, the section I shows an introduction and the state of the art, section II presents the unified power quality conditioner UPQC, section III describes the generalized reactive power theory applied to the iUPQC (dual topology, section IV shows the numerical simulations and the results and section V presents the conclusions of the study. Results: The results for the application of the iUPQC to the compensation of overvoltage are proved and compared with the more representative theory related to compensation of harmonics and low power factor. Conclusions: The control algorithm presented for the unified power quality conditioner in dual topology allows to compensate the overvoltage in three-phase systems as well as voltage and current harmonics and the low power factor.

    Examples of two closed lagoons with extensive growth of Recent microbialites showing variable surface morphology and internal structure are found on Isla Angel de la Guarda in the Gulf of California. Comparable lagoonal microbialites also occur ashore from Ensenada El Quemado on the adjacent peninsular mainland of Baja California. The perimeters of all three lagoons feature crusted structures indicative of thrombolites with a knobby surface morphology 2 cm to 3 cm in relief and internal clotting without any sign of laminations. Outward from this zone, thrombolitic construction thins to merge with a white calcified crust below which a soft substratum of dark organic material 4 cm to 6 cm in thickness is concealed. The substratum is laminated and heavily mucilaginous, as observed along the edges of extensive shrinkage cracks in the overlying crust. The thrombolitic crust is anchored to the shore, while the thinner crust and associated stromatolitic mats float on the surface of the lagoons. Laboratory cultures of the dark organic material yielded the solitary cyanobacterium Chroococcidiopsis as the predominant taxon interspersed with filamentous forms. In decreasing order of abundance, other morphotypes present include Phormidium, Oscillatoria, Geitlerinema, Chroococus, and probably Spirulina. The larger of the two island lagoons follows an east-west azimuth and covers 0.225 km2, while the smaller lagoon has a roughly north-south axis and covers only 0.023 km2. The salinity of water in the smaller lagoon was measured as148 ppt. Pliocene strata along the edge of the smaller modern lagoon include siltstone bearing calcified platelets suggestive of a microbial origin. Dry lagoons abandoned during the later Quaternary occur inland at higher elevations on the island, but retain no fossils except for sporadic white crusts cemented on cobbles around distinct margins. Raised Quaternary lagoons parallel to the big lagoon on Isla Angel de la Guarda are partly obscured by flood

    Urbanization has a profound influence on regional meteorology in mega cities like Los Angeles. This influence is driven by changes in land surface physical properties and urban processes, and their corresponding influence on surface-atmosphere coupling. Changes in meteorology from urbanization in turn influences air quality through weather-dependent chemical reaction, pollutant dispersion, etc. Hence, a real-world representation of the urban land surface properties and urban processes should be accurately resolved in regional climate-chemistry models for better understanding the role of urbanization on changing urban meteorology and associated pollutant dynamics. By incorporating high-resolution land surface data, previous research has improved model-observation comparisons of meteorology in urban areas including the Los Angeles basin, and indicated that historical urbanization has increased urban temperatures and altered wind flows significantly. However, the impact of urban expansion on air quality has been less studied. Thus, in this study, we aim to evaluate the effectiveness of resolving high-resolution heterogeneity in urban land surface properties and processes for regional weather and pollutant concentration predictions. We coupled the Weather Research and Forecasting model with Chemistry to the single-layer Urban Canopy Model to simulate a typical summer period in year 2012 for Southern California. Land cover type and urban fraction were determined from National Land Cover Data. MODIS observations were used to determine satellite-derived albedo, green vegetation fraction, and leaf area index. Urban morphology was determined from GIS datasets of 3D building geometries. An urban irrigation scheme was also implemented in the model. Our results show that the improved model captures the diurnal cycle of 2m air temperature (T2) and Ozone (O3) concentrations. However, it tends to overestimate wind speed and underestimate T2, which leads to an underestimation of O

    Many science and research skills are taught by osmosis in graduate programs with the expectation that students will develop good communication skills (speaking, writing, and networking) by observing others, attending meetings, and self reflection. A new National Science Foundation Graduate Teaching Fellows in K- 12 Education (GK-12; http://ehrweb.aaas.org/gk12new/) program at UCLA (SEE-LA; http://measure.igpp.ucla.edu/GK12-SEE-LA/overview.html ) attempts to make the development of good communication skills an explicit part of the graduate program of science and engineering students. SEE-LA places the graduate fellows in two pairs of middle and high schools within Los Angeles to act as scientists-in- residence. They are partnered with two master science teachers and spend two-days per week in the classroom. They are not student teachers, or teacher aides, but scientists who contribute their content expertise, excitement and experience with research, and new ideas for classroom activities and lessons that incorporate inquiry science. During the one-year fellowship, the graduate students also attend a year-long Preparing Future Faculty seminar that discusses many skills needed as they begin their academic or research careers. Students are also required to include a brief (two-page) summary of their research that their middle or high school students would be able to understand as part of their published thesis. Having students actively thinking about and communicating their science to a pre-college audience provides important science communication training and helps contribute to science education. University and local pre- college school partnerships provide an excellent opportunity to support the development of graduate student communication skills while also contributing significantly to the dissemination of sound science to K-12 teachers and students.

    2015-01-01

    Drawing on recent research in urban policy studies and social studies of technology, this paper examines the capability of urban energy regimes in adapting to environmental policy pressures. Focusing on the case of the City of Los Angeles, we critically analyze the transformative capacity of the city's recent energy and climate policies and the innovation patterns of its urban infrastructure regime. This case study suggests that despite considerable success in switching from coal to renewable energies, the patterns of sociotechnical change in Los Angeles still tend to supplement and sustain the existing regime. Sociotechnical change in Los Angeles tends to unfold incrementally through adjustments within the established patterns of the existing regime. - Highlights: • Theory-guided case study on the transition of the urban energy regime in Los Angeles. • Evaluation of the transformative capacity of environmental policies. • Assessment of the adaptability and innovation patterns of urban infrastructure regimes. • The policy changes have sustained the existing regime and unfold incrementally

    Phase III of the Los Angeles International Airport Runway Incursion Studies was conducted, under an agreement with HNTB Corporation, at the NASA Ames FutureFlight Central (FFC) facility in June 2003. The objective of the study was the evaluation of a new center-taxiway concept at LAX. This study is an extension of the Phase I and Phase II studies previously conducted at FFC. This report presents results from Phase III of the study, in which a center-taxiway concept between runways 25L and 25R was simulated and evaluated. Phase III data were compared objectively against the Baseline data. Subjective evaluations by participating LAX controllers were obtained with regard to workload, efficiency, and safety criteria. To facilitate a valid comparison between Baseline and Phase III data, the same scenarios were used for Phase III that were tested during Phases I and II. This required briefing participating controllers on differences in airport and airline operations between 2001 and today.

    1980-01-01

    A case-control study was conducted among women in Los Angeles County to investigate possible causes of intracranial meningiomas. Questionnaires sought information from patients and from a neighbor of each one on characteristics and past experiences that might be associated with the development of this disease. Information was obtained on 188 matched patient-neighbor pairs. Three primary factors appeared to be associated with meningioma occurrence: 1) a history of head trauma (odds ratio = 2.0, p = 0.01), 2) consumption of certain cured meats (odds ratio = 2.8, p = less than 0.01), and 3) exposure to medical and dental diagnostic X-rays to the head. For diagnostic X-rays, the strongest association was with early exposure (less than 20 yr old) to full-mouth dental X-ray series

    1985-01-01

    The security requirements of the XXIII Summer Olympic Games at Los Angeles provided a challenge unparalleled in the history of the modern games. This paper discusses the dynamics involved and suggests that the principles used are applicable to many of today's security environments. The success of the Intrusion Detection Systems (IDS) employed at each of the three Olympic villages and at the Piper Technical Center is a known fact. How it was accomplished is addressed in a straightforward, systematic way. The paper also recognizes the contributions made by the security community, law enforcement agencies, the government, military, the security industry and RandD organizations. It was a team effort that reflected the spirit of the games and the American ''can-do'' attitude
