description: "Quantum communication is the art of transferring a quantum state from one place to another". The capability of distributing quantum states allows, for instance, provably secure communication and, in the near future, will enable the interconnection of quantum computers to establish a quantum internet. A convenient way to send quantum states from one place to another is to encode them into photons and distribute them using optical bres. The distance over which this can be achieved is still limited to a few hundred of kilometers. However, it can be extended in principle to arbitrary long distances by means of quantum repeaters. The realization of such quantum repeaters will require the engineering and interfacing of heterogeneous elements such as entangled photon-pair sources, quantum memories and entanglement swapping operations. The main goal of this thesis is to develop and study the compatibility of the main elements required to build a frequency multiplexed quantum repeater. This architecture requires a frequency multimode entangled photon pair source which, for example, could be implemented exploiting the process that involves the interaction of a strong light pulse with a non-linear crystal. Such a process is versatile and allows easy tailoring of the photon-pair spectral properties in order to match the requirements of the frequency multiplexed quantum repeater architecture. First, as a precursor of such a photon pair source, we developed a novel heralded single photon source that involves spectrally resolved single photon detection and on-demand frequency shifting. These capabilities are also essential tools in a frequency multiplexed quantum repeater. Next, we demonstrated the compatibility of such a sources with frequency multimode photonic quantum memories by performing spectrally multiplexed storage of single photons. We also tested the capability of high- delity storage of photons encoding quantum information in their polarization degree of freedom. Finally, we showed that entanglement swapping operations, i.e. Bell-state measurements, can be performed using photon pair sources compatible with quantum memories, quantum repeater architectures, and real-world scenarios. While a lot of e ort remains to be done, in the work presented in this thesis we demonstrated that all the key elements required to build a frequency multiplexed quantum repeater can be built and eventually be interfaced. The main obstacles towards that goal and possible ways to overcome them are also discussed.
Definition, Detection, and Recovery of Single-Page Failures, a Fourth Class of Database Failures

description: The three traditional failure classes are system, media, and transaction failures. Sometimes, however, modern storage exhibits failures that differ from all of those. In order to capture and describe such cases, single-page failures are introduced as a fourth failure class. This class encompasses all failures to read a data page correctly and with plausible contents despite all correction attempts in lower system levels. Efficient recovery seems to require a new data structure called the page recovery index. Its transactional maintenance can be accomplished writing the same number of log records as today's efficient implementations of logging and recovery. Detection and recovery of a single-page failure can be sufficiently fast that the affected data access is merely delayed, without the need to abort the transaction.

description: Objective: To examine differences in asthma prevalence and emergency department (ED) visits for asthma between non-Hispanic black and white children, and factors that might explain those differences, in a large, nationally representative sample covering the period 1997 to 2003. Methods: Bivariate and multivariate regression analyses (with logit and multinomial logit methods) were conducted with a sample consisting of all non-Hispanic black and white children (< 18 years of age) from the 1997 to 2003 rounds of the National Health Interview Survey. Models included a progressively larger set of controls for factors that might explain racial differences in asthma prevalence and ED visits for asthma. Results: Being black was associated with a greater likelihood of currently having asthma and with a greater likelihood of having gone to the ED for asthma treatment in the past 1 year. Elevated asthma risks for black children were robust after controlling for a host of child and family characteristics that might explain them. Conclusions: Black children are more likely to have asthma and to experience ED visits for asthma, compared with otherwise comparable white children, and these racial disparities cannot be explained by differences in measurable child or family characteristics. These results suggest that racial disparities in asthma continue to pose risks for black children, and they point to the need for additional research into potential explanations and remedies.

description: Sudden unexpected death in epilepsy (SUDEP) is believed to result from breathing failure during or shortly after a seizure, but the mechanisms behind this respiratory dysfunction remain unknown. A recently discovered period of local tissue hypoxia that occurs during and following a seizure in the brain regions involved in the seizure provides a novel hypothesis for the neurobiological mechanism underlying SUDEP. This thesis used mouse models of seizures and seizure-induced death to explore the hypothesis that SUDEP is the result of seizure-induced hypoxia in brainstem breathing centers. Mice died following generalized, convulsive seizures with epileptiform activity in the brainstem. A brainstem breathing center became severely hypoxic exclusively during and after fatal seizures, following which breathing ceased and the heart stopped beating. These results suggest that seizure-induced hypoxia in brainstem breathing centers is a potential mechanism of the respiratory dysfunction that causes SUDEP and provides a novel target for preventative therapies.

description: The effects of aliovalent rare earth substitution on the physical properties of Sr0.3Ca0.7Fe2As2 solid solutions are explored. Electrical transport, magnetic susceptibility and structural characterization data as a function of La substitution into (Sr_1-y_Ca_y)_1-x_La_x_Fe2As2 single crystals confirm the ability to suppress the antiferromagnetic ordering temperature from 200 K in the undoped compound down to 100 K approaching the solubility limit of La. Despite up to ~30% La substitution, the persistence of magnetic order and lack of any signature of superconductivity above 10 K present a contrasting phase diagram to that of Ca1-xLaxFe2As2, indicating that the suppression of magnetic order is necessary to induce the high-temperature superconducting phase observed in Ca1-xLaxFe2As2.

description: A nationally representative sample of basic and paramedic emergency medical service providers in the United States was surveyed to assess their willingness to respond to terrorist incidents. EMTs were appreciably (9-13%) less willing than able to respond to such potential terrorist-related incidents as smallpox outbreaks, chemical attacks, or radioactive dirty bombs (p < 0.0001). EMTs who had received terrorism-related continuing medical education within the previous 2 years were twice as likely (OR = 1.9, 95% CI 1.9, 2.0) to be willing to respond to a potential smallpox dissemination incident as those who indicated that they had not received such training. Timely and appropriate training, attention to interpersonal concerns, and instilling a sense of duty may increase first medical provider response rates.
The social emergence of health : a theoretical interpretation and empirical application of Pierre Bourdieu's relational theory of social action in a three-dimensional Canadian field
Creators: name: Burnett, Patrick John
Publisher: name: University of British Columbia
Year: 2011

description: Pierre Bourdieu's theory of social action has been the inspiration for an array of diverse health studies seeking to better understand the nature of social stratification and its relation to health behaviours and outcomes. While several of his well-known theoretical concepts, such as social capital, cultural capital and habitus, have garnered a great deal of attention in the health research community, the nature of their application has for the most part been limited to deterministic schemas examining relationships between social position and social action. There are as yet no health-related studies that offer a comprehensive theoretical account of Bourdieu’s ‘constructivist structuralism,’ incorporating all of his theoretical conceptions of field, habitus, capital, doxa and time. In light of these theoretical and empirical oversights, I offer a health-relevant re-envisioning of Bourdieu's expansive body of work and examine the implications of his relational framework for health research. Drawing upon a relational exploratory analytic method called multiple correspondence analysis and using original Canadian survey data from Vancouver and Toronto, Canada, I translate my interpretation of Bourdieu’s theoretical principles into a thoroughly Bourdieusian empirical depiction of a health-relevant three-dimensional geometric social space. The visual mapping of social space revealed seven different groupings of individuals whose common attributes and dispositions are socially patterned around health-related behaviours and outcomes, illuminating distinct spaces of social differentiation within which healthy and unhealthy individuals are located.

description: This volume contains the papers presented at the second international workshop on Logics for Component Configuration (LoCoCo 2011) which was associated with the International Conference on Principles and Practice of Constraint Programming (CP 2011) and which took place on September 12, 2011 in Perugia, Italy. Representing and solving configuration problems is a hot topic of great importance for many application domains. For example, modern software distributions are based on the notion of components, which denote units of independent development and deployment. Components provide the necessary flexibility when organizing a complex software distribution, but also are a challenge when it comes to selecting components from a large repository of possible choices, and configuring these components according to user needs, resource constraints, and interdependencies with other components. Some well-known examples of complex systems of components in the world of Free and Open Source software are the different distributions for GNU/Linux, BSD, or Eclipse plugins. The LoCoCo workshop focus on logic-based methods for specifying and solving complex configuration problems. The goal of the workshop was to bring together both researchers and practitioners active in the area of component configuration of systems, using different modeling and solving techniques, such as constraint and logic programming, description logics, satisfiability and its extensions. The workshop was an opportunity to discuss common and complementary solutions for solving component configuration.

description: High-power microwave (HPM) devices are generally vacuum-based devices that transform electron beam energy into microwaves with peak powers above 100 MW from 1-300 GHz. Solid-state HPM devices provide more compactness and greater reliability while consuming less power. Nonlinear transmission lines (NLTLs) provide a solid-state alternative to HPM generation by sharpening the input pulses from a pulse forming network to create output oscillations.The first section of this dissertation evaluates and explores the feasibility of using nonlinear composites containing ferroelectric (e.g., Ba2/3Sr1/3TiO3, BST) and/or ferromagnetic (e.g., Ni1/2Zn1/2 Fe2O4, NZF) inclusions in a linear polymer host (polydimethylsiloxane, PDMS) to tune NLTL properties for HPM applications. Appropriately modelling and designing NLTLs using nonlinear composites require accurately characterizing their linear and nonlinear electromagnetic properties. We first studied the electromagnetic properties of the composites using theoretical, numerical, and experimental approaches. Incorporating these composite models and characterizations into NLTL simulations will be discussed.Vacuum-based HPM devices, such as magnetrons and crossed-field amplifiers, generally operate in the space-charge-limited region, which corresponds to the maximum current possible for insertion into the device. This motivated studying the space-charge-limited current and electron flow in a two-dimensional (2D) planar diode with various crossed-magnetic fields using particle-in-cell (PIC) simulations. For non-magnetically insulated diodes (electrons emitted from the cathode can reach the anode), analytical and/or semi-empirical solutions are derived for electrons with nonzero monoenergetic initial velocity that agree well with PIC simulations. For magnetically insulated conditions, we developed new metrics using simulations and analytic theories to assess electron cycloidal and Brillouin flow to understand the implications of increasing injection current for 2D diodes. These analyses provide details on the operation of these devices at high currents, particularly virtual cathode operation, that may elucidate behavior near their limits of operation.

description: The wildlife industry in Namibia has shown tremendous growth over the past decades and is currently the only extensive animal production system within the country that is expanding. Several factors are responsible for the dramatic increase in wildlife in range and numbers across Namibia, with the most important being the devolution of rights over wildlife by the state to freehold landowners and communal conservancies. Tourism, live sales and trophy hunting have significantly contributed to the tremendous growth, however they cannot alone sustain further growth. Harvesting wildlife for the purpose of meat production is a viable option, since there is a demand for healthy and high quality meat proteins to feed the ever-increasing world population. It is also predicted that Namibia will experience climate changes in the near future which will further necessitate the optimal management of wildlife herds. The need to hygienically harvest and process game spearheaded the writing of a guideline booklet with the intention of it being used by Namibian game farmers and game harvesting teams. The authors are proud having the opportunity to launch the second edition of this booklet at this symposium.

description: We investigated the influence of climate on the ring width and xylem anatomy of two co-occurring pines (Pinus nigra Arn. and P. sylvestris L.) in the mountains of east-central Spain in order to test their utility for dendroclimatic reconstructions. We developed chronologies of ring width, mean lumen diameter and mean cell-wall thickness (in the earlywood, latewood, and the total annual ring) and the number of cells between 1960 and 2006. Drought, expressed as the standardized precipitation-evapotranspiration index (SPEI), was the main climatic driver of tree radial growth, although trees were also sensitive to temperature (negative effect in previous autumn and current summer) and precipitation (with a general positive effect). P. sylvestris response was stronger to climate of the current year, whereas the effect of previous-year climate was more important for P. nigra. Warm and dry summers reduced ring width, tracheid lumen, and wall thickness in both species, whereas warm winter-spring temperatures had the opposite effect, primarily for P. sylvestris. Previous-year or early-season conditions mainly affected earlywood features, whereas latewood was more responsive to summer climate. Overall, climate appeared to be a stronger limiting factor for P. sylvestris. During periods of drought, cell-wall thickness was reduced while lumen width increased in the latewood of P. sylvestris. This could compromise its hydraulic safety against drought-induced cavitation as our site was close to the southern and dry edge of the species distribution area. Our results suggest that anatomical variables record different and stronger climate information than ring width variables, especially in P. sylvestris. Reconstruction models for SPEI at the 3-month scale were developed for July–August and September– October using principal components regression. The best models included anatomical and width variables of both pine species suggesting that tracheid chronologies can be useful for drought reconstructions especially at mesic sites or with species that encode a mixed drought and temperature-precipitation signal.

description: Disasters, whether resulting from terrorism or natural events, have a dramatic impact on the health and well-being of children. Studies after the terror attacks of September 11, 2001, in New York City and the 1995 Oklahoma City bombing and countless reports on the impact of natural disasters on children show that a child’s mental health can suffer from direct and indirect exposure to these events. Children may react to a disaster or act of terrorism in a variety of ways. These reactions are influenced by age, developmental level, intellectual capacity, individual and family support systems, personality, and other factors. Common manifestations of psychological trauma in young children include regression, clinging behavior, inattentiveness, aggressiveness, bed-wetting, somatic complaints, irritability, social withdrawal, nightmares, and crying. Longer-lasting effects may include depression, anxiety, adjustment disorders, posttraumatic stress disorder, and interpersonal or academic difficulties. Some children are particularly vulnerable to post disaster trauma because of preexisting psychosocial stressors (homelessness, foster care, exposure to violence, etc.), low socioeconomic status, or special needs (including cognitive delays and prior mental illness). These post disaster reactions may not manifest until well after the event and could persist for years.
Cellular and molecular biology of Wnt signaling and versican expression in myofibroblast differentiation
Creators: name: Carthy, Jonathon Morgan
Publisher: name: University of British Columbia
Year: 2011

description: Wound healing is a complex and dynamic process that restores tissue integrity after injury, but also contributes pathologically to the development of fibrosis. Growing evidence suggests a role for Wnt signaling during normal and aberrant wound healing. The proteoglycan versican is a target of Wnt signaling that is expressed following injury and accumulates pathologically in many chronic inflammatory conditions. In this dissertation, I hypothesized that Wnt signaling and its target versican are key regulators of mesenchymal cell phenotype. In Aim 1, I demonstrated that treatment of cultured fibroblasts with Wnt3a, a canonical Wnt ligand, stimulates the formation of a myofibroblast-like phenotype characterized by increased expression of smooth muscle α-actin. These changes appear to be mediated by Wnt3a upregulating the expression of TGF-β and its associated signaling through SMAD2 in a β-catenin-dependent mechanism. In Aim 2, I show that Wnt3a alters the phenotype of vascular smooth muscle cells and stimulates the formation of a contractile and secretory phenotype in these cells that is associated with increased gap junction communication. Again, these changes occurred through a mechanism that was dependent on canonical Wnt signaling. In Aim 3, I explored the functional roles of versican by examining its expression following injury to cultures of valve myofibroblasts. My data indicate that versican is secreted as extracellular matrix following injury to valve cells, and suggests a role for the membrane receptor CD44 in organizing this provisional versican matrix. In Aim 4, I delved further into the functional roles of versican by expressing this proteoglycan in murine fibroblasts. In this aim I showed that versican expression promotes myofibroblast differentiation, and these changes appear to be mediated by activation of TGF-β signaling. Lastly, in Aim 5, I explored potential intracellular functions for versican, and provide evidence to suggest versican localizes to the nucleus in mesenchymal cells where it regulates the organization of the mitotic spindle during cell division. Collectively, these data suggest Wnt signaling and versican are key regulators of mesenchymal cell phenotype, and as such, are important mediators of a wound healing response.

description: This paper proposes a computationally efficient method of solving evaluation problem of Hidden Markov Model (HMM) with a given set of discrete observation symbols, number of states and probability distribution matrices. The observation probability for a given HMM model is evaluated using an approach in which the probability evaluation is reduced to the problem of evaluating the product of matrices with different powers and formed out of state transition probabilities and observation probabilities. Finding powers of a matrix is done by using the computationally efficient diagonalization method thereby reducing the overall computational effort for evaluating the Evaluation problem of HMM.The proposed method is compared with the existing direct method. It is found that evaluating matrix power by diagnolisation method is more suitable than that of the direct, method.

Hurricane Rita (2005)

description: Following Hurricanes Katrina and Rita, Louisiana school-based health centers (SBHCs) were called on to respond to a sharp increase in mental health needs, especially for displaced students coping with grief, loss, trauma, and uncertainty. To assess the impact of the hurricanes on the students and the needs of SBHC mental health providers (MHPs), we surveyed MHPs in each of the SBHCs under the auspices of the Louisiana Department of Health and Hospitals, Office of Public Health. SBHC practitioners from around the state reported that mental health service utilization rose during the 2005–2006 school year, but utilization of services increased most significantly in schools receiving the majority of displaced students. Anxiety and adjustment problems were noted as increasing the most following the hurricanes. A multitude of other conditions was also reported. By the time of this survey in April 2006, the reported prevalence of most symptoms had declined, but all remained above their pre-hurricane levels. Selfreported needs of SBHC MHPs are also discussed in light of the major natural disasters.

description: Emergent gravity is aimed at constructing a Riemannian geometry from U(1) gauge fields on a noncommutative spacetime. But this construction can be inverted to find corresponding U(1) gauge fields on a (generalized) Poisson manifold given a Riemannian metric (M, g). We examine this bottom-up approach with the LeBrun metric which is the most general scalar-flat Kahler metric with a U(1) isometry and contains the Gibbons-Hawking metric, the real heaven as well as the multi-blown up Burns metric which is a scalar-flat Kahler metric on C^2 with n points blown up. The bottom-up approach clarifies some important issues in emergent gravity.

Early childhood education

description: The authors examine black, white, and Hispanic children's differing experiences in early childhood care and education and explore links between these experiences and racial and ethnic gaps in school readiness. Children who attend center care or preschool programs enter school more ready to learn, but both the share of children enrolled in these programs and the quality of care they receive differ by race and ethnicity. Black children are more likely to attend preschool than white children, but may experience lower-quality care. Hispanic children are much less likely than white children to attend preschool. The types of preschool that children attend also differ. Both black and Hispanic children are more likely than white children to attend Head Start. Public funding of early childhood care and education, particularly Head Start, is already reducing ethnic and racial gaps in preschool attendance. The authors consider whether further increases in enrollment and improvements in quality would reduce school readiness gaps. They conclude that incremental changes in enrollment or quality will do little to narrow gaps. But substantial increases in Hispanic and black children's enrollment in preschool, alone or in combination with increases in preschool quality, have the potential to decrease school readiness gaps. Boosting enrollment of Hispanic children may be especially beneficial given their current low rates of enrollment. Policies that target low-income families (who are more likely to be black or Hispanic) also look promising. For example, making preschool enrollment universal for three- and four- year-old children in poverty and increasing the quality of care could close up to 20 percent of the black-white school readiness gap and up to 36 percent of the Hispanic-white gap.

description: The first formal protected area in Africa was proclaimed in June 1894 in the Zuid-Afrikaansche Republiek (ZAR). This protected area was followed four years later by the forerunner of the Kruger National Park. In 1926 the second national park in Africa was proclaimed in the eastern Lowveld of South Africa, and named after Paul Kruger, a former president of the ZAR. In the following year a total of three cars visited the park, and by 1979 visitors had increased to 400,000 per annum. Visitor numbers doubled from 1956 to 1963, between 1963 and 1980, and from 1980 to 1995. In 2014 a total of 1.6 million visitors entered the national park. Of this figure, day visitors comprise77 percent of the total. Visitor facilities in the Kruger National Park currently comprise 4048 beds and 653 campsites in 25 rest camps, 805 kilometers of tarred roads and 1720 kilometers of gravel roads. Since 2002 a total of 334 beds in 17 concession lodges have been added. Visitor numbers are increasing at between 6 and 7 percent per annum, and will double within 11 to 12 years. During peak holiday periods, this equates to 2.5 overnight visitors per km of road, compared to 1.4 overnight visitors per kilometre for Hluhluwe-iMfolozi Game Reserve. In the southern half of the Kruger Park, where 70 percent of accommodation is concentrated, densities increase to 2.97 overnight visitors per km of road. Given the rapid increase in accommodation in the past years, the question should be asked if this is sustainable. Will the Kruger Park be able to accommodate 3.2 million visitors by 2025 and 6.4million visitors by 2036?Can the national park continue absorbing increasing numbers of visitors and what will the environmental impact be of such an action? Can wildlife tourism be sustainable when human populations and economies continue to grow? If accommodation and roads cannot be extended indefinitely, what, then, are the alternatives? Are there too many visitors, or is the problem one of inadequate management of visitors? And what lessons can be learned from high-density tourism destinations in other parts of the world? Can government be expected to establish new protected areas and visitor facilities in countries where there are so many urgent socio-economic needs? And what role can private protected areas and game ranches play in meeting the growing demand for nature-based tourism? This paper examines these issues and proposes a course of action for the future.

description: Abstract: Generally, the general heat flow equations describing the flow of heat through a Plane wall, and through a finite fin insulated at the tip are analyzed by calculus method. Laplace transformation has been applied to analyze boundary value problems arising in the areas of engineering, science and technology. The flow of heat through a Plane wall with equally scattered heat sources between its faces, and through a finite fin with one end attached to a thermal source maintained at fixed temperature and other end (i.e. tip) insulated can be obtained easily by analyzing the general heat flow equations via the Laplace transform method and it will come out to be very effective mathematical tool applied to analyze the general heat flow equations. This paper presents the application of Laplace transformation to the general heat flow equations for obtaining the flow of heat through a Plane wall with equally scattered heat sources between its faces, and through a finite fin with one end attached to a thermal source maintained at fixed temperature and other end (i.e. tip) insulated.

description: Critical race theorists (CRT) have cogently argued the need for anti-racist struggles in the post-civil rights era to address the fact that integration has hardly resolved the continued marginalization and discrimination of African Americans in housing, employment, and many other dimensions and to reflect on how law facilitates racial subordination in the post-civil rights era. However, this Essay suggests that these arguments can be better understood and enriched by a deep appreciation of the breathtaking legacy of Hubert Henry Harrison (1883-1927) and a close reading of his works. As a working class activist and intellectual in both the Socialist Party and the Industrial Workers of the World (IWW), Harrison was later a major influence in Marcus Garvey's nationalist movement and the New Negro Movement, editor of The Voice and The Negro World, and the founder of the Liberty League. Largely lost to history, Harrison's astonishing body of work on racism and the political issues of his time force us to rethink a period of African American history that typically has been regarded as a low point in the struggle against racism and white supremacy. Yet in fact, Harrison found answers to the questions that would haunt advocates of racial equality for years to come.
A Paradox of State-Dependent Diffusion and How to Resolve It

description: Consider a particle diffusing in a confined volume which is divided into two equal regions. In one region the diffusion coefficient is twice the value of the diffusion coefficient in the other region. Will the particle spend equal proportions of time in the two regions in the long term? Statistical mechanics would suggest yes, since the number of accessible states in each region is presumably the same. However, another line of reasoning suggests that the particle should spend less time in the region with faster diffusion, since it will exit that region more quickly. We demonstrate with a simple microscopic model system that both predictions are consistent with the information given. Thus, specifying the diffusion rate as a function of position is not enough to characterize the behaviour of a system, even assuming the absence of external forces. We propose an alternative framework for modelling diffusive dynamics in which both the diffusion rate and equilibrium probability density for the position of the particle are specified by the modeller. We introduce a numerical method for simulating dynamics in our framework that samples from the equilibrium probability density exactly and is suitable for discontinuous diffusion coefficients.

THE USE OF GRAPHIC ORGANIZERS IN TEACHING EFL READING SKILLS
Creators: name: Axrorova, Munisaxon
Publisher: name: Zenodo
Year: 2025

description: This study explores the effectiveness of using graphic organizers (GOs) in teaching English as a Foreign Language (EFL) reading skills. Graphic organizers help learners visually structure information, identify key ideas, and improve text comprehension. Grounded in schema theory and dual coding theory, this research highlights how visual tools enhance knowledge retention and comprehension. Using a mixed-methods approach, the study collected data through pre- and post-tests, classroom observations, and student feedback. The findings indicate that the use of graphic organizers significantly improves students’ ability to understand texts, identify main ideas, and make inferences. Additionally, students demonstrated increased motivation and engagement in reading activities. This study confirms that graphic organizers serve as an effective instructional strategy for EFL learners and should be integrated into reading lessons.
Public Funding and Enrollment in Formal Child Care in the 1990s

description: Although the share of all 3‐ and 4‐year‐old children enrolled in center‐based care and early education has grown steadily in recent decades, rates of enrollment for children from low‐income families still lag behind those for children from families with high incomes. During the 1990s, growing public funding for compensatory preschool education and means‐tested child‐care assistance had the potential to increase the availability of free or low‐cost formal child‐care arrangements and thus the attendance of low‐income children. This article analyzes repeated cross‐sectional data on formal child‐care attendance from the October Current Population Survey as well as data on state‐level funding. The results indicate that increases in public funding are positively associated with the probability that low‐income young children attended formal care. These results also suggest that gaps in formal care between low‐ and high‐income families would have widened in the absence of public investments.

Flexible generation of correlated photon pairs in different frequency ranges

description: The feasibility to generate correlated photon pairs at variable frequencies is investigated. For this purpose, we consider the interaction of an off-resonant laser field with a two-level system possessing broken inversion symmetry. We show that the system generates non-classical photon pairs exhibiting strong intensity-intensity correlations. The intensity of the applied laser tunes the degree of correlation while the detuning controls the frequency of one of the photons which can be in the THz-domain. Furthermore, we observe the violation of a Cauchy-Schwarz inequality characterizing these photons.

Hurricane Katrina (2005)

description: Operation Assist, a joint initiative of Columbia University's National Center for Disaster Preparedness and the Children's Health. Fund was formed after Hurricane Katrina hit the Gulf Coast of the United States in August 2005. Mental health, medical, and public health professionals have spent one year addressing the needs of victims through direct work and research programs, which have resulted in findings relevant to disaster preparedness, resilience, and the creation of child-focused mental health programs post-disaster. While the immediate impact of a disaster is ubiquitous and widespread, children are most likely to require mental health intervention following a disaster. It also is important to care for families and service providers who also are at risk. Operation Assist staff have worked closely with local community leaders as well as with key health and mental health officials to develop relevant programs to meet the mental health needs of children and families. The proposed presentation will describe one year's work with children and families affected by Hurricane Katrina. Program findings, recommendations for future work and implications for policy, delivery and practice that are applicable to under served communities impacted by mass trauma around the world will be discussed.
