description: Final results of a detailed analysis of p+p elastic scattering data are presented, utilizing the quark-diquark model of protons in a form proposed by Bialas and Bzdak. The differential cross-section of elastic proton-proton collisions is analyzed in a detailed and systematic manner at small momentum transfers, starting from the energy range of CERN ISR at $ \sqrt{s}= 23.5 $ GeV, including also recent TOTEM data at the present LHC energies at $\sqrt{s} = 7$ TeV. These studies confirm the picture that the size of proton increases systematically with increasing energies, while the size of the constituent quarks and diquarks remains approximately independent of (or only increases only slightly with) the colliding energy. The detailed analysis indicates correlations between model parameters and also indicates an increasing role of shadowing at LHC energies. Within the investigated class of models, a simple and model-independent phenomenological relation was discovered that connects the total p+p scattering cross-section to the effective quark, diquark size and their average separation. Our best fits indicate, that the relative error of this phenomenological relation is 10-15% in the considered energy range.

description: The needs of children and youth who experience mental health difficulties, as well as the needs of their families, cannot be addressed adequately without solid policy foundations at both state and federal levels. Unclaimed Children Revisited: The Status of Children's Mental Health Policy in the United States aims to document and assess how well child mental health policies across the 50 states and three territories respond to the needs of children and youth with mental health problems, those at risk, and their families. Comprising a national study and four sub-studies, this report presents a range of data collected from service users, providers, family members, youth advocates, and state and county system leaders across the child serving spectrum. The report then uses these data to identify state- and federal-level policy implications and recommendations with the goal of promoting improved mental health service delivery through policy reform.

Evolution of the trophic niche and food web structure
Creators: name: Ingram, Travis
Publisher: name: University of British Columbia
Year: 2011

description: Food webs – networks of predator-prey interactions – are of fundamental importance to the ecological and evolutionary dynamics of biodiversity. The stability and functioning of food webs can be dependent on their 'vertical' structure: the distribution of species' trophic positions, the length of food chains and the prevalence of omnivory. Food web interactions such as predation, resource competition and intraguild predation can be potent agents of natural selection, driving evolutionary responses that feed back to reconfigure the food web. The structure and function of food webs thus arises from an interplay of ecological and evolutionary processes. My thesis describes four studies of the evolutionary ecology of food webs. First, I test whether trophic position evolution is associated with speciation events in Sebastes rockfish. My phylogenetic comparative analyses find no signal of change at speciation in the evolution of trophic position or trophic morphology. Instead, speciation events in rockfish appear to be primarily associated with divergence in depth habitat in the ocean. Next, I use an evolutionary assembly model to explore how the strength of foraging trade-offs influences the structure and temporal dynamics of food webs, as well as patterns of trait evolution. Across a range of trade-off strengths, the amount of omnivory in a food web is positively related to both species turnover and the degree of convergence in trophic position evolution. I then fit macroevolutionary models to Sebastes trophic position data. The data support a model of recurrent evolution in a constrained trait space, as predicted for omnivorous consumers. Finally, I examine the ecological and evolutionary consequences of intraguild predation on three spine stickleback (Gasterosteus aculeatus) by prickly sculpin (Cottus asper). My collaborators and I use comparative and experimental studies to show that sculpin presence in lakes is associated with the evolution of antipredator and pelagic foraging morphology in stickleback, leading to reduced predator vulnerability, increased zooplanktivory, and changes to the structure of the food web. These studies address a number of important questions about how evolutionary processes influence food web structure and function, and illustrate the work that remains to be done in this exciting area of research.

Ram pressure stripping in elliptical galaxies: I. the impact of the interstellar medium turbulence

description: Elliptical galaxies contain X-ray emitting gas that is subject to continuous ram pressure stripping over timescales comparable to cluster ages. The gas in these galaxies is not in perfect hydrostatic equilibrium. Supernova feedback, stellar winds, or active galactic nuclei (AGN) feedback can significantly perturb the interstellar medium (ISM). Using hydrodynamical simulations, we investigate the effect of subsonic turbulence in the hot ISM on the ram pressure stripping process in early-type galaxies. We find that galaxies with more turbulent ISM produce longer, wider, and more smoothly distributed tails of the stripped ISM than those characterised by weaker ISM turbulence. Our main conclusion is that even very weak internal turbulence, at the level of <15% of the average ISM sound speed, can significantly accelerate the gas removal from galaxies via ram pressure stripping. The magnitude of this effect increases sharply with the strength of turbulence. As most of the gas stripping takes place near the boundary between the ISM and the intraclustermedium (ICM), the boost in the ISM stripping rate is due to the "random walk" of the ISM from the central regions of the galactic potential well to larger distances, where the ram pressure is able to permanently remove the gas from galaxies. The ICM can be temporarily trapped inside the galactic potential well due to the mixing of the turbulent ISM with the ICM. The galaxies with more turbulent ISM, yet still characterised by very weak turbulence, can hold larger amounts of the ICM. [Abridged]

description: The non-Hermitian PT-symmetric quantum-mechanical Hamiltonian $H=p^2+x^2(ix)^ε$ has real, positive, and discrete eigenvalues for all $ε\geq 0$. These eigenvalues are analytic continuations of the harmonic-oscillator eigenvalues $E_n=2n+1$ (n=0, 1, 2, 3, ...) at $ε=0$. However, the harmonic oscillator also has negative eigenvalues $E_n=-2n-1$ (n=0, 1, 2, 3, ...), and one may ask whether it is equally possible to continue analytically from these eigenvalues. It is shown in this paper that for appropriate PT-symmetric boundary conditions the Hamiltonian $H=p^2+x^2(ix)^ε$ also has real and {\it negative} discrete eigenvalues. The negative eigenvalues fall into classes labeled by the integer N (N=1, 2, 3, ...). For the Nth class of eigenvalues, $ε$ lies in the range $(4N-6)/3

description: To better understand who is served by child care subsidy systems and what services they receive, research is needed that examines the dynamics of subsidy use across multiple state policy contexts. Such research has been limited by the lack of comparable micro-data at the state level. Child Care Policy Research Partnerships funded by the U.S. Department of Health and Human Services have helped to fill this gap by constructing comparable, analyzable data sets in several states.

This study made use of data sets constructed by three of the Child Care Research Partnerships. Consortium members representing Illinois, Maryland, Massachusetts, and Oregon joined together to build a collaborative, cross-state research design. Researchers in Texas, who were already engaged in similar research, agreed to join the project. Researchers from each of the states met together several times over a two-year period to develop comparable longitudinal data sets using administrative data from state child care subsidy systems. The research team included policy experts familiar with each of the five states and analysts familiar with administrative data and analytic methods. State agency partners played a critical role in helping the research partners understand data elements and policies in each state, and provided valuable feedback on the study results and interpretations.

This study provides important new information about the characteristics of children and families who received subsidies, the services they received, the length of time they received services, and the stability of children’s care arrangements while in the subsidy system.

description: Despite Social Security’s undeniable success at providing income protection for families, we now face national proposals that would dramatically alter the program. Creating private accounts to replace part of the current system represents a radical departure from the program’s original design. Proponents argue that such accounts would ultimately provide greater security.

But security for whom? What about child beneficiaries—how would they be affected? What about surviving spouses of workers who die, and disabled workers and their families? What about Social Security’s original promise that hard-working people and their families would not be consigned to destitution simply because of early death or disability? These questions have barely been acknowledged, let alone addressed.

description: With an unparalleled focus on employment, the 1996 federal welfare reforms changed the nature of cash assistance programs for low-income families. By the end of the decade, welfare caseloads had reached their lowest level since 1969. Prior to these changes, employment rates among single mothers had begun to rise, and the trend continued throughout the 1990s. At the same time, child poverty declined steadily, reaching its lowest level since 1979, and the percent of low-income children living in families with at least one working parent increased. Although researchers disagree about the precise causes of these trends, the trends themselves have focused new attention on low-income families in the work force. Observers across the political spectrum have recognized that low-wage employment—even if full-time—may be insufficient to meet a family's basic needs. This recognition has led to new thinking about the role of government policies in helping low-income working families move toward economic security. This policy brief series focuses on state policy options that have the potential to improve children's economic security by increasing family income. More specifically, the series examines policies that seek to increase family income by encouraging, supporting, and rewarding work.

description: We study a one-dimensional wire with strong Rashba and Dresselhaus spin-orbit coupling (SOC), which supports Majorana fermions when subject to a Zeeman magnetic field and in proximity of a superconductor. Using both analytical and numerical techniques we calculate the electronic spin texture of the Majorana end states. We find that the spin polarization of these states depends on the relative magnitude of the Rashba and Dresselhaus SOC components. Moreover, we define and calculate a local "Majorana polarization" and "Majorana density" and argue that they can be used as order parameters to characterize the topological transition between the trivial system and the system exhibiting Majorana bound modes. We find that the local "Majorana polarization" is correlated to the transverse spin polarization, and we propose to test the presence of Majorana fermions in a 1D system by a spin-polarized density of states measurement.

Scholars of Indigenous politics have recently focused on the importance of interrogating the sexualized and heteronormative landscape of settler colonialism, which has led to the proliferation of anti-queer violence within Indigenous nations. As such, the central tasks of this study are to determine how Two-Spirit Queer (2SQ) people engage in practices of resistance and freedom, as well as the factors that account for a queer Indigenous politics. Specifically, this study is interested in 2SQ life and politics among Blackfoot people. The thesis also examines how 2SQ people are problematically situated within the politics of “Two Spirit Reconciliation” as it propagates settler-homonationalism. Throughout the thesis, I argue that Indigenous territorialities, and the relational networks they carry, are central to the political resurgence of 2SQ people.

description: In the framework of research into radioactive waste disposal, this paper presents some tests carried out to investigate the effects of temperature on the changes in permeability of Boom between 20 and 90 deg C. Constant head permeability tests were carried out in a high pressure isotropic compression tests at various temperature and isotropic stresses. The results show that the changes in permeability of Boom clay with temperature are only due to the changes in viscosity of free water with temperaure. This demonstrates on the one hand that the water involved in transfer at various temperatures is free water and on the other hand that there is apparently only few changes in the status of adsorbed water with respect to temperature between 20 and 90 deg C.
title: Spatio-temporal mapping of sub-Arctic benthic communities
Creators: name: Charmley, Kaitlyn
Publisher: name: Memorial University of Newfoundland
Year: 2023

description: Spatial studies of benthic communities rarely incorporate a temporal aspect into their construction, despite the fact that organisms can exhibit spatio-temporal patterns. Construction of benthic community maps often involve the association of spatially-continuous acoustic layers with in situ samples (ground-truthing); often image and/or video data. Most current habitat mapping studies are built from a single ground-truthing event, which makes the maps a simple snapshot of the distribution of organisms and does not consider temporal variability. The goal of this thesis was to explore the importance of incorporating seasonality into investigations on benthic organisms habitat selection, at both the community and species levels. The first objective explores the spatio-temporal changes that occur in the communities and the implications in the production of benthic community maps. The second objective focuses on one economically-important species, snow crab (Chionoecetes opilio) and investigates the abiotic factors influencing its habitat selection and how these drivers change seasonally. The community maps produced in part one presented two to five different communities depending on the season, with map differences caused by the changes in densities and location of individual taxa. Part two revealed that fine-scale habitat preferences of snow crab was driven by temperature, slope, and in the winter, seafloor hardness. Recommendations are made to researchers regarding timing and frequency of ground-truthing data collection. This study is one of the first to produce predictive maps based on a spatio-temporal seafloor dataset for a sub-Arctic megabenthic community in Canada. It emphasized the importance of incorporating temporal coverage into benthic research to accurately represent communities. This will increase the effectiveness of management of these marine areas , so they can remain biodiverse and economically productive.
Mixed Mimetic Spectral Element Method for Stokes Flow: A Pointwise Divergence-Free Solution

description: In this paper we apply the recently developed mimetic discretization method to the mixed formulation of the Stokes problem in terms of vorticity, velocity and pressure. The mimetic discretization presented in this paper and in [50] is a higher-order method for curvilinear quadrilaterals and hexahedrals. Fundamental is the underlying structure of oriented geometric objects, the relation between these objects through the boundary operator and how this defines the exterior derivative, representing the grad, curl and div, through the generalized Stokes theorem. The mimetic method presented here uses the language of differential $k$-forms with $k$-cochains as their discrete counterpart, and the relations between them in terms of the mimetic operators: reduction, reconstruction and projection. The reconstruction consists of the recently developed mimetic spectral interpolation functions. The most important result of the mimetic framework is the commutation between differentiation at the continuous level with that on the finite dimensional and discrete level. As a result operators like gradient, curl and divergence are discretized exactly. For Stokes flow, this implies a pointwise divergence-free solution. This is confirmed using a set of test cases on both Cartesian and curvilinear meshes. It will be shown that the method converges optimally for all admissible boundary conditions.
In the middle of nowhere? A sociological guide to the beaten tracks of backpacking in the former British Empire
Creators: name: William, Flynn
Publisher: name: University of British Columbia
Year: 2011

description: Since the 1970s backpacking travel has become an increasingly popular and desirable pursuit among young people from western countries. Guidebooks such as Lonely Planet sold young people the practical know-how that would allow them to travel ‘off-the-beaten-track’. The off-the-beaten-track travel experiences of present-day backpackers’ are one way in which youth lifestyle, geography and identity are consumed and produced away from home and apart from the everyday world. This thesis provides an historical, textual and ethnographic analysis of the practices and discourses which distinguish travel from tourism, and it examines how particular destinations and experiences are considered more challenging, and therefore more valuable, than others. In particular it seeks to answer the question of what makes India such a ‘special place’ in the world of backpacking as a ‘litmus test’ for off-the-beaten-track travel. It begins by analyzing the historical precursors and ideological antecedents of the discourses and practices of independent travel and tourism in 19th Europe, with a focus on England and the role played by independent guidebooks in that period. The textual strategies employed in the most popular guidebooks today, those published by Lonely Planet, are then analyzed in connection with the production and consumption of particular backpacking enclaves in Canada, Ireland, and India, where the promise of travel as a self-cultivating, authentic, and valuable activity is realized. Finally, through a combination of detailed, in-depth, qualitative interviews with 24 backpackers in Canada, India and Ireland, historical and contemporary analyses of the Lonely Planet brand and guidebooks, as well as a multi-sited ethnography in three popular backpacker destinations of Vancouver, Delhi, and Cork, the thesis analyzes how the ideological codes of travel and tourism are historically produced, textually and orally mediated, and geographically circulated in the field of backpacking travel.

description: This brief seeks to inform policymakers and others about the difficulties faced by low-income working parents as they strive to make progress in the workforce. Using data from NCCP's Family Resource Simulator, it highlights ways in which the current structure of work support policies often leads to unintended consequences. As low-wage workers increase their earnings above the federal poverty level, their families begin to lose eligibility for government work supports. Given that some of these benefits drop off quickly, earning more does not always improve a family's financial bottom line.

description: Accessibility standards are commonplace. While this progress is something to be championed, it can leave an institutional repository in a difficult situation. How do you uphold accessibility standards when you are not in creating the materials that are being added to your IR? This session will start by looking at the policy and potentially political considerations, as well as the practical aspects of implementing the policy. How do you implement the standards? What stake-holder buy in do you need? Is there technology that can help? Are you actually able to acquire the technology? Who is going to pay for the technology? Will AI truly save us all? And, because of the inevitable way that things like this usually go, how do you formulate Plans B-D just in case things do not go according to plan/take longer to implement? This presentation is coming from librarians who are currently working through this process and will outline what we've done so that others (hopefully) don't have to experience the same. Commiseration and comments from the audience will be highly encouraged.

If $f_0$ is of degree $n = 2^l \cdot m$, where $m$ is odd and $l$ is a non-negative integer, after an initial finite sequence of polynomials $f_0, f_1, ..., f_{s}$ with $s \leq l+3$, the degree of $f_{i+1}$ is twice the degree of $f_i$ for any $i \geq s$.

description: Das Thema unerfüllter Kinderwunsch und Kinderwunschbehandlung ist aufgrund des steigenden Erstgebärendenalters in unserer Gesellschaft von immer zentralerer Bedeutung. Den Patienten stehen neben der ärztlichen Kompetenz vielfältige Informationswege zur Wissensaneignung oder zur Recherche über vorhandene Kinderwunschzentren zur Verfügung. Ziel dieser Arbeit ist es mithilfe eines Fragebogens, welcher in den reproduktionsmedizinischen Ambulanzen des ZRA im UKH Halle und des Universitätsklinikums RWTH Aachen ausgegeben wurde zu evaluieren, wie verschiedene Informationsquellen durch Kinderwunschpatienten genutzt werden und wie diese mit der Zufriedenheit, dem subjektiv eingeschätzten Vorkenntnissen und den Prioritäten bei der Wahl ihres Kinderwunschzentrums korrelieren.
description: The issue of unfulfilled desire for children and fertility treatment is increasingly important in our society due to the rising average age at which women have their first child. Besides having access to medical expertise, patients nowadays have recourse to a variety of ways of gathering information on and acquiring knowledge about this issue and of conducting research on existing fertility centers. Using a questionnaire issued by ZRA reproductive medicine clinics in the UKH Halle and the RWTH Aachen University Hospital the aim of this work is to evaluate how different sources of information are used by fertility patients and how they relate to satisfaction, subjective prior knowledge and priorities in the choice of fertility centers.

description: We discuss and provide nontrivial evidence for a large class of dualities in three-dimensional field theories with different gauge groups. We match the full partition functions of the dual phases for any value of the couplings to underpin our proposals. We focus on two classes of models. The first class, motivated by the AdS/CFT conjecture, consists of necklace U(N) quiver gauge theories with non chiral matter fields. We also consider orientifold projections and establish dualities among necklace quivers with alternating orthogonal and symplectic groups. The second class consists of theories with tensor matter fields with free theory duals. In most of these cases the R-symmetry mixes with IR accidental symmetries and we develop the prescription to include their contribution into the partition function and the extremization problem accordingly.

description: Thermodynamic properties of the spinless Falicov-Kimball model are studied on a triangular lattice using numerical diagonalization technique with Monte-Carlo simulation algorithm. Discontinuous metal-insulator transition is observed at finite temperature. Unlike the case of square lattice, here we observe that the finite temperature effect is not able to smear out the discontinuous metal-insulator transition seen in the ground state. Calculation of specific heat (C_v) shows single and double peak structures for different values of parameters like on-site correlation strength (U), f-electron energy (E_f) and temperature.

description: Dr. R. Michael Fisher presents the basic idea of feariatry (and feariatrics) as an alternative perspective on the fear-disease (i.e., dis-ease) humans can easily suffer from. Using a philosophy of fearlessness and fearism, he presents us with two stories of transdisciplinary ways of approaching fear/trauma and effects of violence. The use of spiritual and cultural ritual, from family to a whole city (Bogota, Columbia) provides us today with e.g.,'s of ways we can improve our working with fear (and, feariatry).

On the nonlinear stability of mKdV breathers

description: A mathematical proof for the stability of mKdV breathers is announced. This proof involves the existence of a nonlinear equation satisfied by all breather profiles, and a new Lyapunov functional which controls the dynamics of small perturbations and instability modes. In order to construct such a functional, we work in a subspace of the energy one. However, our proof introduces new ideas in order to attack the corresponding stability problem in the energy space. Some remarks about the sine-Gordon case are also considered.

Poor families

description: Nearly 40 percent of American children live in families with incomes below 200 percent of the federal poverty level—the amount that research suggests is needed for most families to be economically self-sufficient. Currently, 200 percent of the federal poverty level is $36,800 a year for a family of four.3 Most families with income below 200 percent of the poverty level—low-income families—have at least one working parent. Although families with incomes between 100 and 200 percent of the poverty level are not classified officially as poor, many face material hardships and financial pressures similar to those faced by families who are officially poor. Missed rent payments, utility shut offs, inadequate access to health care, unstable child care arrangements, and running out of food are not uncommon for families with income below 200 percent of the poverty level. Even though 85 percent of children in low-income families have at least one working parent, many of these families cannot get ahead simply by working more. Low wages, work-related expenses, the loss of public benefits, and the bite of payroll and other taxes make it difficult for low-income working families to work their way to long-term economic security. Without additional supports, nearly 40 percent of American children have parents who have little chance of working their way to economic self-sufficiency anytime soon. This report examines the progress made by low-income children and families in the 1990s, when child poverty declined substantially. It focuses on the important role that public policies have played in supporting low-wage employment. But it also highlights the limits of low-wage employment—low-wage work, by itself, is insufficient to move families from poverty to economic self-sufficiency. The economic downturn, rising unemployment, and cuts in public work supports have compounded the challenges faced by low-income families. The report concludes with suggestions for how policymakers can help low-income families make financial progress.
Present, Engaged, and Accounted For: The Critical Importance of Addressing Chronic Absence in the Early Grades

description: This report seeks to raise awareness of the critical importance of chronic early absence, synthesize available data on the scope of the challenge, and share emerging insights about how schools and communities can use chronic early absence to identify and address challenges affecting the social, educational and physical well-being of children and their families before problems become intractable. While parents are responsible for getting their children to school every day, schools and communities need to recognize and address the barriers and challenges that may inhibit them from doing so, especially when they are living in poverty. Large numbers of chronically absent students could indicate systemic problems that affect the quality of the educational experience and/or the healthy functioning of the entire community.

Social security beneficiaries--Economic conditions

description: Despite the fact that Social Security provides more benefits to children than any other social program, recent debates about Social Security have ignored our nation's youngest citizens. Over 5 million children in the United States benefit from Social Security, either directly as beneficiaries or indirectly as members of households that receive a monthly Social Security check. Social Security is not just a retirement program. It is also a family insurance program for workers, their spouses, and their children. Social Security provides income support to disabled workers and their families, as well as to the survivors of workers who die. Nearly a third of Social Security beneficiaries receive support through the survivor and disability components of the program. These insurance protections have kept many middle- and low-income families from falling into poverty because of a parent's death or disability. This policy brief provides basic information about Social Security and describes the vital protections the program offers to workers and their families. It also poses questions that policymakers should consider as the debate over Social Security continues.

description: We study the real-time emission of single electrons from a quantum dot coupled to a one dimensional conductor, using exact diagonalization on a discrete tight-binding chain. We show that from the calculation of the time-evolution of the one electron states, we have a simple access to all the relevant physical quantities in the system. In particular, we are able to compute accurately the finite frequency current autocorrelation noise. The method which we use is general and versatile, allowing to study the impact of many different parameters like the dot transparency or level position. Our results can be directly compared with existing experiments, and can also serve as a basis for future calculations including electronic interactions using the time dependent density-matrix renormalisation group and other techniques based on tight-binding models.
