title: An Exploration of the Dialectical Tensions and Competing Goals of Adult Children of Mentally Ill Parents

description: Mental illness is a pervasive health epidemic in the United States and worldwide, and available data suggest that mentally ill adults are statistically more likely to be parents than non-parents. The prevalence and continued growth of parental mental illness means that millions of children in the United States have a parent with some form of mental health issues.
This dissertation contributes to and extends existing literature on children of mentally ill parents by exploring 15 adult children’s subjective perspectives on how they navigate the tension-wrought experience of having a mentally ill parent, and how this has implications for the management of their identity, relational, and instrumental goals. Examined through the lens of relational dialectics theory (Baxter & Montgomery, 1996) and a multiple goals perspective, analysis revealed that adult children of mentally ill parents confront conflicting, contradictory forces in making sense of their parent’s illness and the role that it plays in their lives. Specifically, adult children reported feeling a strong sense of interdependence with their parent and a desire to have a closer relationship with them, but simultaneously expressed a strong need and desire for disconnection and maintenance of a life separate from their parent’s challenges. Additionally, adult children noted conflicting goals with regard to privacy management about their parent’s illness, acknowledging that an underlying, but pervasive societal stigma surrounding mental health keeps them from freely disclosing to others about their parent’s illness, but indicating that a certain strategic degree of openness was required in order to meet certain instrumental and relational goals. Finally, participants revealed many fears and anxieties that they had about the future as a result of the unstable nature of their parent’s mental illness, while at the same time expressing a sense of acceptance and stability with the predictably unpredictable nature of their lives.
After presenting an analysis of the data, the implications of the findings for children of mentally ill parents are explored, including, but not limited to, how the results of this exploratory study could be integrated into therapeutic and support interventions for families of those struggling with mental health issues. Finally, the limitations of the study are addressed.

description: We verify numerically that in the context of general relativity (GR), flat models which have the same $Ω_{\rm m}$ and CMB shift parameter $R$ but different $H(a)$ and $w(a)$ also have very similar (within less than 8%) growth of perturbations even though the dark energy density evolution is quite different. This provides a direct connection between geometrical and dynamical tests of dark energy and may be used as a cosmological test of general relativity.

description: The detection and characterization of supermassive black holes (SMBHs) in local low mass galaxies is crucial to our understanding of the origins of SMBHs. This statement assumes that low mass galaxies have had a relatively quiet cosmic history, so that their black holes have not undergone significant growth and therefore can be treated as relics of the original SMBH seeds. While recent studies have found optical signatures of active galactic nuclei (AGNs) in a growing population of dwarf galaxies, these studies are biased against low metallicity and relatively merger-free galaxies, thus missing precisely the demographic in which to search for the relics of SMBH seeds. Here, we report the detection of the [\ion{Si}{6}]1.963~$μ$m coronal line (CL), a robust indicator of an AGN in the galaxy SDSS~J160135.95+311353.7, a nearby ($z=0.031$) low metallicity galaxy with a stellar mass approximately an order of magnitude lower than the LMC ($M_*\approx10^{8.56}$~M$_\odot$) and no optical evidence for an AGN. The AGN bolometric luminosity implied by the CL detection is $\approx10^{42}$~erg~s$^{-1}$, precisely what is predicted from its near-infrared continuum emission based on well-studied AGNs. Our results are consistent with a black hole of mass $\approx~10^5$~M$_\odot$, in line with expectations based on its stellar mass. This is the first time a near-infrared CL has been detected in a low mass, low metallicity galaxy with no optical evidence for AGN activity, providing confirmation of the utility of infrared CLs in finding AGNs in low mass galaxies when optical diagnostics fail. These observations highlight a powerful avenue of investigation to hunt for low mass black holes in the JWST era.

description: The effect of silica-promotion on the reduction of iron oxides in hydrogen was investigated using in situ X-ray diffraction and aberration-corrected transmission electron microscopy to understand the mechanism of reduction and the identity of the iron(II) silicate phase that has historically been designated as the cause of the iron-silica interaction in such materials. In the absence of a silica promoter the reduction of hematite to α-Fe proceeds via magnetite. Silica promoted amorphous iron oxide is reduced to α-Fe via stable magnetite and wüstite phases. During reduction of silica-promoted iron oxide, Fe0 diffuses out of the amorphous silica-promoted iron oxide matrix upon reduction from Fe2+ and coexists with an amorphous Fe-O-Si matrix. Certain portions of wüstite remain difficult to reduce to α-Fe owing to the formation of a protective silica-containing layer covering the remaining iron oxide regions. Given sufficient energy, this amorphous Fe-O-Si material forms ordered, crystalline fayalite.

description: The major solar event on 2006 December 13 is characterized by the approximately simultaneous occurrence of a heap of hot ejecta, a great two-ribbon flare and an extended Earth-directed coronal mass ejection. We examine the magnetic field and sunspot evolution in active region NOAA AR 10930, the source region of the event, while it transited the solar disk centre from Dec. 10 to Dec. 13. We find that the obvious changes in the active region associated with the event are the development of magnetic shear, the appearance of ephemeral regions and fast rotation of a smaller sunspot. Around the area of the magnetic neutral line of the active region, interaction between the fast rotating sunspot and the ephemeral regions triggers continual brightening and finally the major flare. It is indicative that only after the sunspot rotates up to 200$^{\circ}$ does the major event take place. The sunspot rotates at least 240$^{\circ}$ about its centre, the largest sunspot rotation angle which has been reported.

description: Charadra Walker Charadra Walker, 1865: 445. Type species: Charadra contigua Walker, 1865, a junior subjective synonym of Charadra deridens (Gueneé). The generic placement of Charadra in relation to other pantheine genera, especially Pseudopanthea and Colocasia, is in need of review, and more than one genus for the species currently placed in Charadra may need to be recognized. Th e morphology of the genus is quite heterogeneous, but important shared genital characters include the following: apex of uncus with slight to very pronounced medial notch; clasper parallel to ventral valve margin (perpendicular in Panthea Hübner) but absent in C. nitens; dorsal tegumen lacking process (lobed in Panthea, prong-like or flange-like in Colocasia); basal costal process absent or highly developed; vesica with two strongly sclerotized cornuti (absent in C. nitens); female ductus bursae sclerotized laterally; corpus bursae lacking signa. Some of the character states treated as autapomorphic for Panthea by Fibiger et al. (2009) are also present in Charadra, including a dorsally membranous aedeagus and the presence of cornuti on the vesica.

description: Estimating the temperature and metal abundance of the intracluster and the intragroup media is crucial to determine their global metal content and to determine fundamental cosmological parameters. When a spatially resolved temperature or abundance profile cannot be recovered from observations (e.g., for distant objects), or deprojection is difficult (e.g., due to a significant non-spherical shape), only global average temperature and abundance are derived. After introducing a general technique to build hydrostatic gaseous distributions of prescribed density profile in potential wells of any shape, we compute the global mass weighted and emission weighted temperature and abundance for a large set of barotropic equilibria and an observationally motivated abundance gradient. We also compute the spectroscopic-like temperature that is recovered from a single temperature fit of observed spectra. The derived emission weighted abundance and temperatures are higher by 50% to 100% than the corresponding mass weighted quantities, with overestimates that increase with the gas mean temperature. Spectroscopic temperatures are intermediate between mass and luminosity weighted temperatures. Dark matter flattening does not lead to significant differences in the values of the average temperatures or abundances with respect to the corresponding spherical case (except for extreme cases).

title: Transcending Static Deployment of Circuits: Dynamic Run-Time Systems and Mobile Hardware Processes for FPGAs
Creators: name: Moseley, Ralph
Publisher: name: University of Kent
Year: 2002

description: The usefulness of reconfigurable hardware has been shown in research and commercial applications. Unquestionably, this has and will lead to, unique avenues of thought within computer science being explored. The interest by researchers in some specific areas has led to manufacturers developing devices which were enhanced in their ability to dynamically be configured within a run-time context. These improvements are on-going and rapid progress is being made, producing high density, system-on-a-chip capable devices, with fast run-time reconfiguration. The advancements in this technology have particularly led to a convergence between software and hardware domains, in the sense that algorithms can be implemented in either; the choice being dependent only in terms of efficiency within the medium itself. Older methods for development with these devices have become rapidly dated and inflexible. Very few suitable tools exist, for example, which are capable of fully utilising the inherent capabilities of such hardware. The approach taken here allows the division between hardware and software to be diminished. Component designs, which may be hardware description language (HDL) based or synthesised algorithms, become easily manipulated and interacted with through a run-time engine, that can deploy elements at will to local or distributed devices. Such entities are essentially hybrid in nature, possessing both hardware and software functionality. These processes are sufficiently self-supporting, to be capable of being used outside of the run-time system within a normal Java development environment. This work explores how hardware entities can become as dynamic as memory based algorithms within conventional von Neumann based systems, providing the means for extending the software programming paradigm into such areas. It analyses the possibilities of applying object-oriented and occam/Communicating Sequential Processes (CSP) based concurrency philosophies to these highly mobile, hardware processes.
Matrix methods in queueing and dynamic programming
Creators: name: Lamond, Bernard Fernand
Publisher: name: University of British Columbia
Year: 2010

description: We investigate some modern matrix methods for the solution of finite state stochastic models with an infinite time horizon. Markov and semi-Markov decision processes and finite queues in tandem with exponential service times are considered. The methods are based on the Drazin generalized inverse and use matrix decomposition. Unlike the related Jordan canonical form, the decompositions considered are numerically tractable and use real arithmetic when the original matrix has real entries. The spectral structure of the transition matrix of a Markov chain, deduced from non-negative matrix theory, provides a decomposition from which the limiting and deviation matrices are directly obtained. The matrix decomposition approach to the solution of Markov reward processes provides a new, simple derivation of the Laurent expansion of the resolvent. Many other basic results of dynamic programming are easily derived in a similar fashion and the extension to semi-Markov decision processes is straightforward. Further, numerical algorithms for matrix decomposition can be used efficiently in the policy iteration method, for evaluating the terms of the Laurent series. The problem of finding the stationary distribution of a system with two finite queues in tandem, when the service times have an exponential distribution, can also be expressed in matrix form. Two numerical methods, one iterative and one using matrix decomposition, are reviewed for computing the stationary probabilities. Job-local-balance is used to derive some bounds on the call congestion. A numerical investigation of the bounds is included. It suggests that the bounds are insensitive to the distribution of the service times.

Conceptual problems are outlined and numerical difficulties are discussed. Both are related to the fact that neither the many-body Hamiltonian nor the wave function of the system appear explicitly in the Density Functional Theory. Similar obstacles are encountered in self-consistent theories utilizing density-dependent effective interactions.

description: In a previous paper the complex-shift method has been applied to self-gravitating spherical systems, producing new analytical axisymmetric density-potential pairs. We now extend the treatement to the Miyamoto-Nagai disc and to the Binney logarithmic halo, and we study the resulting axisymmetric and triaxial analytical density-potential pairs; we also show how to obtain the surface density of shifted systems from the complex-shift of the surface density of the parent model. In particular, the systems obtained from Miyamoto-Nagai discs can be used to describe disc galaxies with a peanut-shaped bulge or with a central triaxial bar, depending on the direction of the shift vector. By using a constructive method that can be applied to generic axisymmetric systems, we finally show that the Miyamoto-Nagai and the Satoh discs, and the Binney logarithmic halo, cannot be obtained from the complex-shift of any spherical parent distribution. As a by-product of this study we also found two new generating functions in closed form for even and odd Legendre polynomials, respectively.

description: We acquired high resolution spectroscopic and low resolution spectropolarimetric observations to achieve the following goals: a) to improve the orbital parameters to allow a more in-depth discussion on the possibility of mass transfer in the binary system, b) to carry out a non-local thermodynamic equilibrium (NLTE) abundance analysis, and c) to search for the presence of a magnetic field. The study of the radial velocities using CORALIE spectra allowed us to significantly improve the orbital parameters. A comparative NLTE abundance analysis was undertaken for theta Car and two other early B-type stars with recently detected magnetic fields, tau Sco and xi^1 CMa. The analysis revealed significantly different abundance patterns: a one-order-of-magnitude nitrogen overabundance and carbon depletion was found in theta Car, while the oxygen abundance is roughly solar. For the stars xi^1 CMa and tau Sco the carbon abundance is solar and, while an N excess is also detected, it is of much smaller amplitude (0.4-0.6dex). Such an N overabundance is typical of the values already found for other slowly-rotating (magnetic) B-type dwarfs. For theta Car, we attribute instead the chemical peculiarities to a past episode of mass transfer between the two binary components. The results of the search for a magnetic field using FORS1 at the VLT consisting of 26 measurements over a time span of ~1.2h are rather inconclusive: only few measurements have a significance level of 3sigma. Although we detect a periodicity of the order of ~8.8min in the dataset involving the measurements on all hydrogen Balmer lines with the exception of the Halpha and Hbeta lines, these results have to be confirmed by additional time-resolved magnetic field observations.

It has been established that the electron conductivity practically does not depend on temperature at some substrate charge. The results obtained are explained by localization of carriers and creation of electron polarons.

description: Polarization and charge transfer are important effects which are difficult to describe using conventional force fields. Charge equilibration models can include both of these effects in large-scale molecular simulations. However, these models behave incorrectly when bonds are broken, making it difficult to use them in the context of reactive force fields. We develop a new method for describing charge flow in molecules -- QTPIE. The QTPIE method is based on charge transfer variables (as opposed to atomic charges) and correctly treats asymptotic behavior near dissociation. It is also able to provide a realistic description of in-plane polarizabilities.

description: There is increasing experimental evidence for fractional quantum Hall effect at filling factor $ν=2+3/8$. Modeling it as a system of composite fermions, we study the problem of interacting composite fermions by a number of methods. In our variational study, we consider the Fermi sea, the Pfaffian paired state, and bubble and stripe phases of composite fermions, and find that the Fermi sea state is favored for a wide range of transverse thickness. However, when we incorporate interactions between composite fermions through composite-fermion diagonalization on systems with up to 25 composite fermions, we find that a gap opens at the Fermi level, suggesting that inter-composite fermion interaction can induce fractional quantum Hall effect at $ν=2+3/8$. The resulting state is seen to be distinct from the Pfaffian wave function.

description: Very recently, the construction of twist actuators from magnetorheological gels and elastomers has been suggested. These materials consist of magnetizable colloidal particles embedded in a soft elastic polymeric environment. The twist actuation is enabled by a net chirality of the internal particle arrangement. Upon magnetization by a homogeneous external magnetic field, the systems feature an overall torsional deformation around the magnetization direction. Starting from a discrete minimal mesoscopic model set-up we work towards a macroscopic characterization. The two scales are linked by identifying expressions for the macroscopic system parameters as functions of the mesoscopic model parameters. In this way, the observed behavior of a macroscopic system can in principle be mapped to and illustratively be understood from an appropriate mesoscopic picture. Our results apply equally well to corresponding soft electrorheological gels and elastomers.

description: Inviscid flow within an evaporating sessile drop is analyzed. The field equation, E^2(Psi)=0, is solved for the stream function. The exact analytical solution is obtained for arbitrary contact angle and distribution of evaporative flux along the free boundary. Specific results and computations are presented for evaporation corresponding to both uniform flux and purely diffusive gas phase transport into an infinite ambient. Wetting and non-wetting contact angles are considered with flow patterns in each case being illustrated. The limiting behaviors of small contact angle and droplets of hemispherical shape are treated. All of the above categories are considered for the cases of droplets whose contact lines are either pinned or free to move during evaporation.

description: Distance to the Large Magellanic Cloud (LMC) is determined using the Cepheid variables in the LMC. We combine the individual LMC Cepheid distances obtained from the infrared surface brightness method and a dataset with a large number of LMC Cepheids. Using the standard least squares method, the LMC distance modulus can be found from the ZP offsets of these two samples. We have adopted both a linear P-L relation and a ``broken'' P-L relation in our calculations. The resulting LMC distance moduli are 18.48+-0.03 mag and 18.49+-0.04 mag (random error only), respectively, which are consistent to the adopted 18.50 mag in the literature.

Finite temperature corrections and embedded strings in noncommutative geometry and the standard model with neutrino mixing

description: The recent extension of the standard model to include massive neutrinos in the framework of noncommutative geometry and the spectral action principle involves new scalar fields and their interactions with the usual complex scalar doublet. After ensuring that they bring no unphysical consequences, we address the question of how these fields affect the physics predicted in Weinberg-Salam theory, particularly in the context of the Electroweak phase transition. Applying the Dolan-Jackiw procedure, we calculate the finite temperature corrections, and find that the phase transition is first order. The new scalar interactions significantly improve the stability of the Electroweak Z string, through the ``bag'' phenomenon described by Watkins and Vachaspati. (Recently cosmic strings have climbed back into interest due to new evidence). Sourced by static embedded strings, an internal space analogy of Cartan's torsion is drawn, and a possible Higgs-force-like `gravitational' effect of this non-propagating torsion on the fermion masses is described. We also check that the field generating the Majorana mass for the $ν_R$ is non-zero in the physical vacuum.

description: Downy mildew, caused by the obligate biotrophic parasite Plasmopara viticola, is one of the most serious grapevine diseases with worldwide distribution. Resistant grapevines can be used to reduce damages caused by the pathogen, recently different levels of susceptibility to P. viticola were detected in some Georgian autochthonous varieties. The aim of the present work was to classify additional Georgian autochthonous varieties into different groups according to their susceptibility to the downy mildew agent in the framework of COST Action FA1003 "East-West Collaboration for Grapevine Diversity Exploration and Mobilization of Adaptive Traits for Breeding". The leaf disk assay defined by the OIV 452-1 protocol was used for screening 61 native varieties of Georgia. Screened varieties showed different degree of resistance: very high – 7 accessions, high - 13, medium - 15, low – 23, and very low - 3 accessions. The results suggest that further resistant genotypes are likely to be found within more than 500 Georgian grapevine cultivars.

description: In Handlungen, Repräsentationen, Diskursen und Gefühlen zum Thema Muttermilchernährung aktualisieren sich gegenwärtig geschlechtliche Responsibilisierungsmomente, die mit Ein- und Ausschlüssen für Frauen als Mütter einhergehen. Damit flankieren sie auch die Frage nach (un)gleichen Geschlechterverhältnissen. Im Gegensatz zum englischsprachigen Raum ist die sozialwissenschaftliche Forschung zur Säuglingsernährung und zum Stillen in Deutschland noch wenig entwickelt. Dies gilt vor allem für qualitativ-praxisanalytische Untersuchungen. Diese Leerstelle nimmt der Beitrag aus einer genderpolitischen und ethnografischen Perspektive in den Blick und analysiert exemplarisch die sozialen Praktiken der professionellen Stillförderung auf einer Geburtshilfestation. Gefragt wird, wie der Körper der Mutter in diesen Settings bearbeitet und als Nährquelle für das Baby funktionsfähig gemacht wird. Die Ergebnisse verdeutlichen, dass das Stillen in der Praxis als problemanfälliger Lerngegenstand konzipiert ist, der ein Arsenal an Hilfen und Problemlösungstechniken aktiviert, die den Mutterkörper reduzieren, fragmentieren und funktionalisieren sowie gleichzeitig als unersetzbar für das kindliche Gedeihen exponieren.

description: Fossil fuels have greatly improved human living standards and saved countless lives. However, today, their continued use threatens human survival, as CO2 levels rise at an unprecedented pace to levels never seen during human existence on earth. This thesis aims at gathering knowledge on solar energy in general and photovoltaic thermal (PVT) and concentrating photovoltaic thermal (C-PVT) in particular. This thesis establishes several key research questions for PVTs and C-PVT collectors and attempts to answer them. A comprehensive market study of solar thermal (ST), photovoltaic (PV) and PVT was conducted to obtain prices and performance. Simulations of the energy output around the world were conducted. A ratio between ST and PV annual output was defined to serve as a tool for comparison and plotted on a world map. A key issue for PVT collectors is how to encapsulate the solar cells in a way that, amongst other things, protects the cell from the thermal expansion of the receiver, has a high transparency, and insulates electrically while at the same time conducts the heat to the receiver. In order to be useful, this analysis must also consider the impacts on the production processes. Several prototypes were constructed, a test methodology was created, and the analysis of the results enabled several conclusions on the validity of the different silicon encapsulations methods. This thesis relies heavily on collector testing with 30 different prototypes of C-PVTs being designed and constructed. Most testing was conducted using steady state method but quasi dynamic was also carried out. From this work, several guidelines were created for the design of collectors in terms of reflector geometry, cell size, string configuration, encapsulation method and several other design aspects. These analyses were complemented with thermal simulations (COMSOL & ANSYS), string layout (LT SPICE) and evaluation of existing installations. Two novel design ideas came from this thesis work, which the author will patent in the coming year. Additionally, raytracing work has been conducted and a new reflector geometry more appropriate for C-PVTs has been found to significantly improve the annual performance. Finally, the current and future position of PVTs in the global energy market is discussed.
description: This thesis is based on work conducted within the industrial post-graduate school REESBE (Resource Efficient Energy Systems in the Built Environment). The projects in REESBE are aimed at key issues in the interface between the business responsibilities of different actors in order to find common solutions for improving energy efficiency that are resource efficient in terms of primary energy and, at the same time, low environmental impact.
