description: We use data from Cassini's Composite Infrared Spectrometer CIRS to map Mimas' surface temperatures and its thermophysical properties. This provides a dramatic improvement on the work in Howett et al. (2011), where the values were determined at only two regions on Mimas (one inside, and another outside of the anomalous region). We use all spatially-resolved scans made by CIRS' focal plane 3 (FP3, 600 to 1100 cm-1) of Mimas' surface, which are largely daytime observations but do include one nighttime one. The resulting temperature maps confirm the presence and location of Mimas' previously discovered thermally anomalous region. No other thermally anomalous regions were discovered, although we note that the surface coverage is incomplete on Mimas' leading and anti-Saturn hemisphere. The thermal inertia map confirms that the anomalous region has a notably higher thermal inertia than its surroundings: 98 +/- 42 J m-2 K-1 s-1/2 inside of the anomaly, compared to 34 +/- 32 J m-2 K-1 s-1/2 outside. The albedo inside and outside of the anomalous region agrees within their uncertainty: 0.45+/-0.08 inside compared to 0.41 +/- 0.07 outside the anomaly. Interestingly the albedo appears brighter inside the anomaly region, which may not be surprising given this region does appear brighter at some UV wavelengths (0.338 microns, see Schenk et al., 2011). However, this result should be treated with caution because, as previously stated, statistically the albedo of these two regions is the same when their uncertainties are considered. These thermal inertia and albedo values determined here are consistent with those found by Howett et al. (2011), who determined the thermal inertia inside the anomaly to be 66 +/- 23 J m-2 K-1 s-1/2 and less than 16 J m-2 K-1 s-1/2 outside, with albedos that varied from 0.49 to 0.70.

description: This paper contributes to the productivity literature by demonstrating novel econometric methods to estimate input-mix efficiency (IME) in a parametric framework. Input-mix efficiency is defined as the potential improvement in productivity with change in input mix. Any change in input-mix (e.g., land to labor ratio) will result in change in productivity. We minimize a nonlinear input-aggregator function (e.g., Constant Elasticity of Substitution) to derive an expression for input-mix efficiency. We estimate a Bayesian stochastic frontier for obtaining mix efficiency using US state-level agricultural data for the period 1960 – 2004. We note significant variation in input-mix efficiency across the states and regions, attributable to diverse topographic, geographic and infrastructure conditions. Furthermore, comparisons of allocative and mix efficiencies provide insightful policy implications. For example, the production incentives such as taxes and subsidies could help farmers in adjusting their input mix in response to changes in input prices, which can affect the US agricultural productivity significantly. We provide a simple way of estimating mix efficiency in an aggregate-input, aggregate-output framework. This framework can be extended by i) using flexible functional forms; ii) introducing various time- and region-varying input aggregators; and iii) defining more sophisticated weights for input aggregators.
Neutron texture analysis of melt-textured YBCO bulk samples

Publisher: name: FID GEO
Year: 1999

description: Neutron texture measurements on YBCO bulk samples show a very sharp texture of the superconducting phase YBa2Cu3O7-x with half-widths of less than 5°. Even with a rather coarse measurement grid of only 722 points per complete pole figure, satisfactory results for the recalculated (002) pole figures could be obtained. However, for a reliable calculation of a complete ODF, finer grids will have to be used. Due to the importance of a good alignment of the c-axes in the material, a quantitative analysis of the (002) pole figures, including an error estimation due to measurement grid and counting statistics, was made. An outline for the determination of a reliable background estimate is given.
What Sociology Teaches Us About Black Women

description: My thesis examines the ways in which Black womanhood is constructed in introductory sociology textbooks. My research adds to the research on the depictions of Black women in sociology textbooks by looking beyond underrepresentation and marginalization to examining how the textbooks are representing Black women and thus constructing the meaning of Black womanhood. My sample consists of 7 best-selling introductory sociology textbooks that are currently used in introductory courses at 5 different universities in the D.C. Metro Area. I used qualitative textual analysis to understand the ways in which the texts construct meaning through the use of language and other discursive practices. My findings reveal that sociology textbooks reinforce hegemonic power through the lack of representation of Black women, as well as constant comparisons Black women's experiences to the white "norm." My analysis also indicates that textbooks can resist those hegemonic representations by contextualizing inequalities and including research and analyses from Black scholars.
The American Adams and Eves : gender, simulacra, and post-history in the eco-dystopian landscapes of West Coast literature
Creators: name: Simpson, William David
Publisher: name: University of British Columbia
Year: 2011

description: The protagonists in eco-dystopian literature are Adams in the city and usually have adversarial interactions with the Eves in the city who are depicted in the texts as tempting them to eat the metaphorical apple, destroying nature in pursuit of wealth and the placation of women. This relationship leads men to act in ways that are, paradoxically, destructive to the species, yet necessary for the short-term propagation of their own genetic line. In fact, this relationship, in which men are encouraged to attain material wealth, much of it with no actual intrinsic value or practical purpose, at the expense of the natural environment, is the cause of the eco-dystopian landscapes these texts depict. The subconscious knowledge of this paradox places extreme stress upon the psyches of men, and the results of this stress play out in the noir, cynicism, and male-centeredness of eco-dystopian literature. Raymond Chandler's The Big Sleep lets us see an eco-dystopian world through the eyes of Detective Marlowe, a private detective who is keenly wary of femme fatales and who, at least in this text, manages to avoid the snares of multiple women. Douglas Coupland's Generation X achieves a similar effect by delivering a narrator who is very close to being devoid of gender. In sharp contrast, at least from the perspective of gender, Chuck Palahniuk's Fight Club may very well be the most masculine text ever written, and Tyler Durden may very well be the most hyper-masculine character. This text actually portrays the literal split of a male mind, so traumatized by the constant pressure to destroy in order to profit, that it creates a separate personality, one that does not obey the male gender role. Lastly, William Gibson's Neuromancer explodes the whole dilemma by not just disobeying the male gender role, but by actually abandoning what is male altogether - that being the physical body. The main character, Case, has developed a distain for his own flesh, and desires to escape it and exist within the matrix, a computer generated cyberspace in which a human consciousness can exist outside the confines of flesh.

description: We re-examine the impact of environmental taxation on health and output, in the presence of labor market frictions. Our main findings are that matching process and wage bargaining introduce new channels of transmission of environmental taxation on the economy such that assuming perfect labor market leads to over-estimate the positive impact of environmental taxation on health. We also demonstrate that rising abatement expenditures as a way of tightening the environmental policy would be better for health than increasing environmental tax in the presence of market labor imperfections.
Quantum Theory and Time Asymmetry

Year: 2003
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The relation between quantum measurement and thermodynamically irreversible processes is investigated. The reduction of the state vector is fundamentally asymmetric in time and shows an observer-relatedness which may explain the double interpretation of the state vector as a representation of physical states as well as of information about them. The concept of relevance being used in all statistical theories of irreversible thermodynamics is shown to be based on the same observer-relatedness. Quantum theories of irreversible processes implicitly use an objectivized process of state vector reduction. The conditions for the reduction are discussed, and I speculate that the final (subjective) observer system might even be carried by a spacetime point.

description: A longstanding goal of the European Union (EU) is to promote efficient trading between price zones via electricity interconnection to achieve a single electricity market between the EU countries. This paper uses a power system model (PLEXOS-EU) to simulate one vision of the 2030 EU electricity market based on European Commission studies to determine the effects of a new interconnector between France and the Single Electricity Market of Ireland and Northern Ireland (SEM). We use the same tool to understand the effects of investment in storage, and the effects of the interaction between storage and additional interconnection. Our results show that both investments in interconnection and storage reduce wholesale electricity prices in France and Ireland as well as reduce net revenues of thermal generators in most scenarios in both countries. However, France is only marginally affected by the new interconnector. Renewable generators see a modest increase in net revenues. The project has the potential for a positive impact on welfare in Ireland if costs are shared between countries and remain below 45 million €/year for the scenarios examined. The owners of the new interconnector between France and SEM see increased net revenues in the scenarios without storage. When storage is included in the system, the new interconnector becomes less profitable.
Stochastic flow simulation and particle transport in a 2D layer of random porous medium
Creators: name: Kurbanmuradov, Orazgeldi A.

Publisher: name: WIAS, Berlin
Year: 2008

description: A stochastic numerical method is developed for simulation of flows and particle transport in a 2D layer of porous medium. The hydraulic conductivity is assumed to be a random field of a given statistical structure, the flow is modeled in the layer with prescribed boundary conditions. Numerical experiments are carried out by solving the Darcy equation for each sample of the hydraulic conductivity by a direct solver for sparse matrices, and tracking Lagrangian trajectories in the simulated flow. We present and analyze different Eulerian and Lagrangian statistical characteristics of the flow such as transverse and longitudinal velocity correlation functions, longitudinal dispersion coefficient, and the mean displacement of Lagrangian trajectories. We discuss the effect of long-range correlations of the longitudinal velocities which we have found in our numerical simulations. The related anomalous diffusion is also analyzed.

title: The management of people at work: strategy, HRM, discourse
Creators: name: Dear, Brian
Publisher: name: The Open University
Year: 1998

description: This thesis critically examines the concept of strategic human resource management (HRM). Existing 'critical' approaches identify prescriptive HRNI literature as 'rhetoric' that does not match 'reality'. Such an approach understands management initiatives as separate, individual, discrete, and ad hoc. However, this thesis develops an alternative perspcctivc, informed by a Foucauldian approach to 'discourse', that understands 'HRM' and 'strategy' as cultural constructs that are used by actors as they 'make sense' of discursively constructed organizational 'realities'. This perspective is then utilized to demonstrate that the existing 'critical' approaches are engaged in particular practices that define strategic HRM in a way that constructs the 'gap' between 'rhetoric' and 'reality' as HRM is simultaneously created as an academic subject. This alternative perspective provides a means of understanding and analysing prescriptive management literature and texts generated from interviews with managers in terms of two different discursively constructed 'rationalities'. Both 'rationalities' establish causal relationships between concepts of environment, organization and individual as organizational 'reality' is constructed. This perspective is utilized in the identification of the connections that are established between the managerial initiatives that are thought of as separate, individual, discrete, and ad hoc by the 'critical' literature. There are two parts to this thesis. The first part describes the development of HM4, outlines a Foucauldian conceptualization of 'discourse, and re-examines prescriptive and 'critical' HRM literature. The second part analyses texts generated from interviews with HRIpersonnel managers in a range of public and private sector organizations. This analysis demonstrates that, while there is great variety in the descriptions of organizational 'reality', connections between concepts of environment, organization and individual arc established as two key 'rationalities' are discursively constructed. It is argued that these 'rationalities' position people and practices within organizational 'reality'.

description: Despite the use of machine learning for many network traffic analysis tasks in security, from application identification to intrusion detection, the aspects of the machine learning pipeline that ultimately determine the performance of the model -- feature selection and representation, model selection, and parameter tuning -- remain manual and painstaking. This paper presents a method to automate many aspects of traffic analysis, making it easier to apply machine learning techniques to a wider variety of traffic analysis tasks. We introduce nPrint, a tool that generates a unified packet representation that is amenable for representation learning and model training. We integrate nPrint with automated machine learning (AutoML), resulting in nPrintML, a public system that largely eliminates feature extraction and model tuning for a wide variety of traffic analysis tasks. We have evaluated nPrintML on eight separate traffic analysis tasks and released nPrint and nPrintML to enable future work to extend these methods.
The structure of the NGC1333-IRAS2 protostellar system on 500 AU scales: an infalling envelope, a circumstellar disk, multiple outflows, and chemistry

description: This paper investigates small-scale structures of dense gas and dust around the low-mass protostellar binary NGC1333-IRAS2 using millimeter-wavelength aperture-synthesis observations from the OVRO and BIMA interferometers. The detected 3 mm continuum emission is consistent with models of the envelope around IRAS2A, based on previously reported submillimeter continuum images, down to the 3", or 500 AU, resolution of the interferometer data. Our data constrain the contribution of an unresolved point source to 22 mJy. Within the accuracy of the parameters describing the envelope model, the point source flux has an uncertainty by up to 25%. We interpret this point source as a cold disk of mass \gtrsim 0.3 M_\odot. The same envelope model also reproduces aperture-synthesis line observations of the optically thin isotopic species C34S and H13CO+. The more optically thick main isotope lines show a variety of components in the protostellar environment: N2H+ is closely correlated with dust concentrations as seen at submillimeter wavelengths and is particularly strong toward the starless core IRAS2C. We hypothesize that N2H+ is destroyed through reactions with CO that is released from icy grains near the protostellar sources IRAS2A and B. CS, HCO+, and HCN have complex line shapes apparently affected by both outflow and infall. In addition to the east-west jet from IRAS2A, a north-south velocity gradient near this source indicates a second, perpendicular outflow. This suggests the presence of a binary companion within 0.3" (65 AU) from IRAS2A as driving source of this outflow. Alternative explanations of the velocity gradient such as rotation in a circumstellar envelope or a single, wide-angle outflow are less likely.

description: Taking into account the recent suggestion that a short gamma-ray burst (GRB) looks like the first 1 sec of a long GRB, we propose that the jet of a GRB consists of multiple sub-jets or sub-shells (i.e., an inhomogeneous jet model). The multiplicity of the sub-jets along a line of sight n_s is an important parameter. If n_s is large (>> 1) the event looks like a long GRB, while if n_s is small (~1) the event looks like a short GRB. If our line of sight is off-axis to any sub-jets, the event looks like an X-ray flash or an X-ray rich GRB. The log-normal distribution of durations of short and long GRBs are also suggested in the same model.

title: Co-Simulation Methods with Variable Communication Step Size and Alternative Approaches for Solving Constrained Mechanical Systems
Creators: name: Meyer, Tobias
Publisher: name: UNSPECIFIED
Year: 2022

description: This dissertation has two parts. The first part deals with co-simulation schemes for mechanical systems, concretely for multibody systems. Applying a co-simulation approach, a large differential-algebraic system is decomposed into several subsystems, which are also multibody systems. Coupling variables are defined to describe the connection between adjacent subsystems. Moreover, a communication time grid has to be introduced. The coupling variables are exchanged only at the communication time points. Within two communication time points, the coupling variables are approximated, so that the subsystems can be computed independently with classical integration schemes to solve initial value problems. Each subsystem can be computed with an appropriate integration scheme and individual integration step sizes. The efficiency of classical time integration schemes is improved by using a step size control algorithm. This doctoral thesis is focused on the development and error analysis for controlling a variable communication step size. The analysis is carried out for coupling techniques with constitutive laws as well as for constraint coupling. Error estimators are derived for several co-simulation methods. With the help of classical methods for step size control, co-simulation can be implemented with variable communication step sizes. Numerical results are presented with convergence plots confirming the results of the error analysis. Furthermore, plots to compare the estimated local errors with the real local errors are depicted. Also, results of co-simulations with variable communication time grids are shown. In the second part of this thesis, alternative approaches for solving constrained mechanical systems are developed. The general idea of the methods are based on the usage of intermediate time points. The approaches are discussed for implicit Runge-Kutta methods, backward differentiation formulas, and the generalized-α method. The approach can also be applied for non-mechanical higher-index systems of differential-algebraic equations.

description: The Paris Agreement has set stringent temperature targets to limit global warming to 2°C above preindustrial level, with efforts to stay well below 2°C. At the same time, its bottom-up approach with voluntary national contributions makes the implementation of these ambitious targets particularly challenging. Climate engineering – both through carbon dioxide removal (CDR) and solar radiation management (SRM) – is currently discussed to potentially complement mitigation and adaptation. Results from integrated assessment models already suggest a significant role for some forms of climate engineering in achieving stringent climate objectives1. However, these estimates and their underlying assumptions are uncertain and currently heavily debated2–4. By reviewing the existing literature and reporting the views of experts, we identify research gaps and priorities for improving the integrated assessment of climate engineering. Results point to differentiated roles of CDR and SRM as complementary strategies to the traditional ones, as well as diverse challenges for an adequate representation in integrated assessment models. We identify potential synergies for model development which can help better represent mitigation and adaptation challenges, as well as climate engineering.

description: The purpose of this research thesis was to develop a method to test for synthetic cannabinoids in a variety of street samples, known as "spice", using a GC-MS. Six samples were tested. Of the six, four contained JWH-122 as a major ingredient and two contained JWH-210 as a major ingredient, with one of the previously mentioned samples containing both. The experiment successfully demonstrates that extraction by methylene chloride is an effective extraction technique for synthetic cannabinoids. In addition, the four liquid samples all contained trace amounts of other JWH compounds, suggesting that cross-contamination occurred in the original manufacturer's laboratory.

description: Neutral atoms can be trapped and manipulated with surface mounted microscopic current carrying and charged structures. We present a lithographic fabrication process for such atom chips based on evaporated metal films. The size limit of this process is below 1$μ$m. At room temperature, thin wires can carry more than 10$^7$A/cm$^2$ current density and voltages of more than 500V. Extensive test measurements for different substrates and metal thicknesses (up to 5 $μ$m) are compared to models for the heating characteristics of the microscopic wires. Among the materials tested, we find that Si is the best suited substrate for atom chips.
Healing Through Recovery: The Potential Benefit of Dramatherapy in East African Refugee Camps
Creators: name: Kashaka, Camille
Publisher: name: American University
Year: 2023

description: The objective of this study is to identify the potential benefits of a dramatherapy program in an East African refugee camp. In order to understand the value of such a program, the methods used include a review of the political/social/economic history of the region of East Africa including texts on conflicts in the area. The main psychological and mental health issues found in the refugee camps were connected to post-traumatic stress disorder (PTSD). For this reason, a review of literature on PTSD was conducted. Also, a vigorous review of literature on current and historical models of dramatherapy, but not excluding psychodrama and sociodrama was conducted. The information found in these texts proved valuable in learning about the treatment of victims of PTSD. Lastly, interviews with experts in these fields were conducted and compiled. The results of this research lead to the conclusion that dramatherapy can be an essential tool in remedying the mental ills brought to and developed in East African refugee camps, but must contain some focus on education and skill-building activities in order to be a community remedy. Current models of dramatherapy promote mental, emotional and spiritual well-being while increasing the ability to be critical and communicative in everyday life. Dramatherapy has the potential to help individuals and groups recover from the trauma they experienced in their homes and in the refugee camps while also fostering an environment for fundamental social and political change.

description: Alates 2017. aasta tulude deklareerimisest ei ole enam võimalik abikaasadel ühist tuludeklaratsiooni esitada. See
on asendatud võimalusega jagada kasutamata jäänud teatud maksusoodustusi abikaasaga. Seadusemuudatusega
kaotasid kõige enam need abikaasad, kellest ainult üks töötas ja tasus riigile tulumaksu. Varem oli võimalus ühises
tuludeklaratsioonis kasutada kõiki maksusoodustusi kahekordselt. Muudatuste järgi saab jagada kasutamata maksusoodustusi, kuid nendel on piirangud. Näiteks üldise maksuvaba tulu korral ei ole võimalik jagada maksimaalset
maksuvaba tulu (6000 eurot), vaid osa sellest, st kuni 2160 eurot.
Eluasemelaenu intresside ja koolituskulude korral ei ole samuti võimalust kasutada ühel abikaasadest kahekordset maksuvabastust, vaid see piirdub ühe isiku maksuvabastusega (kuni 1200 eurot). Ainuke maksusoodustus, kus
ei mängi rolli see, kas saab jagada kasutamata maksusoodustust või esitati ühine tuludeklaratsioon, on täiendav
maksuvabastus laste korral. Abikaasad saavad kasutada täpselt samas mahus maksusoodustust, mis enne seadusemuudatust. Lisapiirangud sellele maksusoodustusele ei ole kehtestatud.
Ühise tuludeklaratsiooni esitamise kaotamisega, kus kõiki maksusoodustusi sai kasutada ühiselt kogumis,
kaotasid veel need maksumaksjad, kes tegid kingitusi ja annetusi, mis on lubatud tuludest maha arvata. Kingituste
ja annetuste korral saab soodustust kasutada ainult selle tegija, abikaasaga seda jagada ei saa. Lisaks ei ole võimalik
kasutada abikaasa tasutud, kuid kasutamata jäänud mahaarvamisi tuludest, mis puudutavad töötuskindlustusmakset, kohustuslikku kogumispensionit ja vabatahtlikku kogumispensionit. Ühise tuludeklaratsiooni esitamise
võimalusest ilma jäämisest kaotasid ka need abikaasad, kes olid küll maksustamisperioodi algul abielus, kuid üks

description: The objective of this study is to identify the potential benefits of a dramatherapy program in an East African refugee camp. In order to understand the value of such a program, the methods used include a review of the political/social/economic history of the region of East Africa including texts on conflicts in the area. The main psychological and mental health issues found in the refugee camps were connected to post-traumatic stress disorder (PTSD). For this reason, a review of literature on PTSD was conducted. Also, a vigorous review of literature on current and historical models of dramatherapy, but not excluding psychodrama and sociodrama was conducted. The information found in these texts proved valuable in learning about the treatment of victims of PTSD. Lastly, interviews with experts in these fields were conducted and compiled. The results of this research lead to the conclusion that dramatherapy can be an essential tool in remedying the mental ills brought to and developed in East African refugee camps, but must contain some focus on education and skill-building activities in order to be a community remedy. Current models of dramatherapy promote mental, emotional and spiritual well-being while increasing the ability to be critical and communicative in everyday life. Dramatherapy has the potential to help individuals and groups recover from the trauma they experienced in their homes and in the refugee camps while also fostering an environment for fundamental social and political change.

description: We study the evolution of the [O/Fe]-[Fe/H] relation and the dependence of the iron abundance on distance from the galactic plane z in a one-zone model for a disk galaxy, starting from the beginning of star formation (Wiebe98). We obtain good agreement with the observational data, including, for the first time, agreement for the [Fe/H]-z relation out to heights of 16 kpc. We also study the influence of the presence of dark matter in the galaxies on the star-formation rate. Comparison of the observed luminosity of the Galaxy with the model prediction places constraints on the fractional mass of dark matter, which cannot be much larger than the fractional mass of visible matter, at least within the assumed radius of the Galaxy, 20 kpc. We studied the evolution of disk galaxies with various masses, which should obey the Tully-Fisher relation, M \propto R^2. The Tully-Fisher relation can be explained as a combination of a selection effect related to the observed surface brightnesses of galaxies with large radii and the conditions for the formation for elliptical galaxies.

description: We study fast-slow versions of the SIR, SIRS, and SIRWS epidemiological models. The multiple time scale behavior is introduced to account for large differences between some of the rates of the epidemiological pathways. Our main purpose is to show that the fast-slow models, even though in nonstandard form, can be studied by means of Geometric Singular Perturbation Theory (GSPT). In particular, without using Lyapunov's method, we are able to not only analyze the stability of the endemic equilibria but also to show that in some of the models limit cycles arise. We show that the proposed approach is particularly useful in more complicated (higher dimensional) models such as the SIRWS model, for which we provide a detailed description of its dynamics by combining analytic and numerical techniques.

Greening Labor Unions: Environmental Concerns of Union Members
Creators: name: Kojola, Erik
Publisher: name: American University
Year: 2023

description: The labor and environmental movements have had a complicated relationship with periods of cooperation as well as conflict, but recently there has been increasing collaboration at the national level. Whether such a trend of cooperation can be sustained will partially depend on grassroots-level connections between the two movements. However, there has been little empirical research on the environmental attitudes of union members, which is important for understanding the potential for shared values between union members and environmental activists. This thesis analyzes 1993, 2000, and 2010 General Social Survey data to examine if the environmental attitudes of people in union households have changed given shifting labor-environment relations and broader political-economic conditions. I find that union membership does not influence environmental concern in weaker economic times (1993 and 2010) but that it has a positive effect on environmental concern in stronger economic times (2000). Thus, union household are generally no less concerned about the environment than non-union households. Therefore, strengthening connections between union members and environmental activists may be a feasible strategy for invigorating both the labor and environmental movements.
title: An investigation of visitor and resident place perceptions of Mid Wales, and an evaluation of the potential of such perceptions to shape economic development in the area
Creators: name: Emanuel, Louise Coralie
Publisher: name: The Open University
Year: 1998

description: The research investigates visitor and resident place perceptions of Mid Wales and evaluates the potential of such perceptions to shape economic development in the area. A review of literature indicated a need for an holistic approach to place. It was suggested that a starting point towards achieving this is to envisage place as three components - the real, the expected and the perceived. The real place is described using secondary statistical information and maps of the area. the expected place is described using topographical writing and guide books. The perceived place is examined through a combination of questionnaires and interviews with residents and visitors. These investigate perceptions of the landscape and economy of Mid Wales. The 'perceived places' of residents and visitors are described. A number of agencies based in Mid Wales were also interviewed to examine i) their perceptions of Mid Wales' ii) the way in which visitor and resident perceptions are incorporated into the policy development process, and, iii) their responses to some of the preliminary outcomes of the research. The research concluded that both residents and visitors have well defined, but different place perceptions of Mid Wales. Visitor perceptions are more affected by the expected place than the real, whilst resident perceptions are more affected by the real place than the expected. There are currently few mechanisms by which place perceptions are directly incorporated into the development process. However, the place perceptions of agencies were found to be close to those of the groups they represented; it is suggested that place perceptions are fundamental truths shared by groups, which are so strong as to actually subconsciously drive the policy development process. Policy implications are suggested, as are ideas for future research.

Allelic variation in gene expression in Populus F₁ hybrids
Creators: name: Zhuang, Yan
Publisher: name: University of British Columbia

description: Plant hybridization can induce phenotypic novelty and speciation as well as genome rearrangements and gene expression changes. Populus hybrids provide a good system to study interspecific hybridization and its genetic and molecular consequences. In this project I determined the allelic variation of gene expression in Populus trichocarpa x Populus deltoides F₁ hybrids using a single-base primer extension assay. Among 30 genes analyzed in four independently formed hybrids, 17 showed above 1.5 fold expression biases for the two alleles, and the expression patterns differed between leaves and stems for 9 genes. These results suggest differential regulation of the two parental alleles in the Populus F₁ hybrids. To determine if the allelic expression biases were caused by hybridization I compared the ratios of species-specific transcripts between a hybrid and clones of its parents. Modes of gene regulation were inferred from the hybrid-parent comparisons. C«-regulation was inferred for 6 out of 19 genes. The remaining 13 genes including 1 controlled by trans-regulation and 12 by combined cis- & trans-regulation showed allelic expression ratios in the hybrid that were significantly different from the parental ratios, suggesting an alteration of the regulation network induced by hybridization.

description: We analyze the gender price gap (GPG) in Central Kenyan vegetable markets. Exploiting differences in the combination of the gender of the household head, the person controlling production, and the seller, we control for other gender related in uences. We cannot identify a signifcant GPG for the population as a whole but find an u-shaped relationship between the GPG and the sold quantities. Also, we observe that female control over marketing is negatively associated with the commercialization of vegetable trade. This indicates that besides the absence of an average GPG, women are disadvantaged in larger scale markets. These findings support recent experimental evidence that the GPG depends on the perceived competence and entitlement as women are traditionally active in small scale local vegetable trade but not in large scale trade in the survey region. Also, it is a warning that women might be left behind in an increasingly commercializing market, even though they traditionally controlled it.

description: Let S^3_r(K) be the oriented 3--manifold obtained by rational r-surgery on a knot K in S^3. Using the contact Ozsvath-Szabo invariants we prove, for a class of knots K containing all the algebraic knots, that S^3_r(K) carries positive, tight contact structures for every r not= 2g_s(K)-1, where g_s(K) is the slice genus of K. This implies, in particular, that the Brieskorn spheres -Sigma(2,3,4) and -Sigma(2,3,3) carry tight, positive contact structures. As an application of our main result we show that for each m in N there exists a Seifert fibered rational homology 3-sphere M_m carrying at least m pairwise non-isomorphic tight, nonfillable contact structures.
