title: Development and verification of semi-blind receiver structures for broadband wireless communication systems
Creators: name: Ma, Teng
Publisher: name: University of Liverpool Repository
Year: 2015

description: The increasingly high demands for high data rate wireless communication services require spectrum- and energy-efficient solutions. In this thesis, a number of energy-efficient semi-blind receiver structures are proposed to perform Doppler spread estimation, channel estimation and equalisation for broadband wireless orthogonal frequency division multiplexing (OFDM) systems. A real-time wireless communication testbed is developed to verify the proposed semi-blind receiver structures. In the first contribution, a semi-blind Doppler spread estimation and Kalman filtering based channel estimation approach is proposed for wireless OFDM systems. A short sequence of reference data is carefully designed and applied as pilot symbols for Doppler spread estimation and channel estimation initialisation of the Kalman filter. Then the estimates of inter-carrier interference (ICI) caused by Doppler spread are gathered into the equivalent channel model and compensated for through channel equalisation, which dramatically reduces the computational complexity. The simulation results show that the proposed approach outperforms the conventional pilot aided Doppler spread and channel estimation schemes. In the second contribution, a semi-blind Doppler spread estimation and independent component analysis (ICA) based equalisation scheme aided by non-redundant precoding is proposed for wireless multiple-input multiple-output (MIMO) OFDM systems. A number of reference data sequences are selected from a pool of orthogonal sequences for two purposes. First, the reference data sequences are superimposed in the source data sequences through non-redundant linear precoding to enable the Doppler spread estimation by minimising the sum cross-correlation between the compensated signals and the rest of the orthogonal sequences in the pool. Second, the same reference data sequences are applied to eliminate the phase and permutation ambiguity in the ICA equalised signals. Simulation results show that the proposed semi-blind MIMO OFDM system can achieve a bit error rate (BER) performance which is close to the ideal case with perfect channel state information (CSI). In the third contribution, a real-time wireless communication testbed is developed with a vector signal generator, a vector signal analyser and a pair of antennas, to verify the effectiveness of the proposed receiver structures over the air in different environments such as Reverberation chamber and office area. Measurement results show a good match with simulation results. Also, a pilot is employed for three purposes at a semi-blind receiver: time synchronisation, Doppler spread estimation and Kalman filtering initialisation, which is an extension of the work in the first contribution.

description: In this paper we address the uniqueness issue in the classical Robin inverse problem on a Lipschitz domain $Ω\subset\RR^n$, with $L^\infty$ Robin coefficient, $L^2$ Neumann data and isotropic conductivity of class $W^{1,r}(Ω)$, $r\textgreater{}n$. We show that uniqueness of the Robin coefficient on a subpart of the boundary given Cauchy data on the complementary part, does hold in dimension $n=2$ but needs not hold in higher dimension. We also raise on open issue on harmonic gradients which is of interest in this context.
title: Genome annotation and metabolic reconstruction of apicomplexan parasites
Creators: name: Shanmugasundram, Achchuthan

Year: 2015

description: The apicomplexans are causative agents of human and animal infections including malaria, toxoplasmosis and theileriosis and have a huge economic and social impact. A number of apicomplexan genomes have been sequenced. However, the annotation of gene functions remains challenging. A semi-automatic approach was used to systematically assign genes to their functions within pathways/networks through the integration of genomic information with biochemical evidence from the literature. This method has resulted in the evidence-based annotation of metabolic functions and the development of organism specific metabolic pathways. A web database named Library of Apicomplexan Metabolic Pathways (LAMP, www.llamp.net) was developed to host the metabolic mappings for Toxoplasma gondii, Neospora caninum, Cryptosporidium and Theileria species and Babesia bovis at present. A comparative analysis of the overall metabolic capabilities of apicomplexan species showed that the metabolic adaptations has evolved for different ecological niches and led to the identification of putative drug targets. The identification of missing enzymes that are essential to complete the metabolic pathways and the identification of a subsection of these missing enzymes from raw genomes demonstrated probable inaccuracies in gene model predictions. The utilisation of T. gondii and N. caninum proteomic datasets and their mapping to alternative gene models showed regions of genes that require further refinement. The evaluation of the quality of two different gene model releases with this peptide evidence showed the importance of integration of RNA-Seq datasets in improving gene models and further improvements that can be made with proteomic datasets. A global post-translational modification (PTM) analysis was carried out for T. gondii and N. caninum via the utilisation of non-enriched proteomic datasets available for these species. This analysis identified proteins of functional importance that have undergone PTMs, particularly methylation, acetylation, phosphorylation and oxidative modifications. All these analyses helped in the improvement of gene models and functional annotation of genes from Apicomplexa genomes.

description: Corpus linguistics is the study of a language as that language is expressed in its text corpus (plural corpora), its body of "real world" text. Corpus linguistics proposes that a reliable analysis of a language is more feasible with corpora collected in the field—the natural context ("realia") of that language—with minimal experimental interference. This paper attempts to analyze the relationship of corpus and linguistics.
title: Identification of a C-FABP-PPARγ-VEGF axis promoting tumorigenicity in prostate cancer cells
Creators: name: Seyed Forootan, Farzad
Publisher: name: University of Liverpool Repository
Year: 2015

description: The over-expression of C-FABP plays an important role in promoting tumorigenicity of prostate cancer. It has been hypothesized that the overexpressed C-FABP may transport an excessive amount of intracellular fatty acids into cancer cells to activate their nuclear receptor PPARγ to trigger a chain of molecular events that may lead to a facilitated malignant progression of the cancer cells. To investigate whether PPARγ involved in activities exerted by C-FABP in prostate cancer, their expression status was assessed in prostate cell lines and tissues. Results showed that their expression levels in malignant cell lines and tissues (cytoplasm and nucleus) were significantly higher than those expressed in benign cells and in BPH and it appeared that their expression levels were increased as the increasing malignancies of the cell lines and tissues. The increased expression of both C-FABP and PPARγ were significantly correlated to a reduced survival time. Suppression of PPARγ in highly malignant prostate cancer cells produced a significant reduction in growth rate (up to 53%), invasiveness (up to 89%) and anchorage-independent growth (up to 94%) in vitro. Suppression of PPARγ in PC3-M cells could significantly reduce the sizes of tumours formed in nude mice by 99%. Tumour incidence was reduced to 10% and the latent period was significantly increased by 3.5 fold. The results in this study also showed that C-FABP promoted VEGF expression and angiogenesis by PPARγ (through the stimulation of the fatty acids transported by C-FABP). When PPARγ was blocked with its antagonists, cells did not respond to stimulation signal produced by fatty acids, even when high level of fatty acids was available. Further study showed that the activated PPARγ regulated VEGF expression through acting with the PPREs in the promoter region of VEGF in prostate cancer. Although androgen can modulate VEGF expression through Sp1/Sp3 binding site on VEGF promoter in androgen-dependent prostate cancer cells, this route was disappeared and gradually replcaced by the C-FABP-PPARγ route as the cells gradually lost their androgen dependency. The results of this study suggested that C-FABP, together with fatty acids, PPARγ and VEGF should be considered as key factors in the fatty acids-initiated signalling pathway that promoted the malignant progression. Therefore, the C-FABP-PPARγ-VEGF axis may be a novel therapeutic target for prostatic cancer.

description: We argue that the stories told about the histories and nature of places, are vehicles for narrating race. Drawing on interviews with professionals and community workers in Butetown in Cardiff and Govanhill in Glasgow, we explore how they negotiated – and contested – racialized histories of place, constructing different versions or claims to belong. Drawing on Henri Lefebvre’s spatial concepts we explore this conceptualization through examination of the two areas that have distinct histories, and present experiences, of migration and racialization. In discussion of the accounts from the two distinct areas, we show that narratives of the past have a political resonance that shape accounts of current experiences of migration. Accounts of place are often related in relationship to comparisons with and narratives of other places and to global processes of trade and migration. Whilst these racialized narratives are contested, they also shape responses to social problems faced by communities.

title: Evaluation of UHRF1 expression in pancreatic cancer
Creators: name: AbuAlainin, Wafa
Publisher: name: University of Liverpool Repository
Year: 2016

description: The ubiquitin-like with PHD and ring finger domains 1 (UHRF1) is a DNA binding protein, involved in epigenetic regulation. UHRF1 expression varies in different cancers, and its role in pancreatic ductal adenocarcinoma (PDAC) is unknown. PDAC is a devastating disease with an overall 5-year survival rate of less than 5 %. Here we report that UHRF1 is frequently overexpressed in PDAC and negatively regulates Keap1, an important component of the Nrf2-mediated cellular stress response pathway. UHRF1 was expressed in 114 of 132 (86%) pancreatic tumours, was associated with larger tumour size (p= 0.02) and had higher expression in tumours compared to matched preneoplastic (PanIN) lesions (n=9). UHRF1 expression varied at different phases of the cell cycle with a peak level at G2/M. Moreover, siRNA-mediated depletion of UHRF1 was associated with a G2/M phase block and induced apoptosis. UHRF1 protein expression levels varied in different PDAC cell lines and reflected the DNA methylation levels in examined sequences. UHRF1 knockdown reduced global DNA methylation in LINE-1 and Alu-V repetitive elements and tumour suppressor-specific (p16Ink4a and RASSF1) promoter methylation. Combining UHRF1 knockdown with 5-aza-deoxycytidine treatment resulted in restoration of P16 levels compared to controls siRNA samples. KEAP1 expression loss was previously reported in ~70 % of PDAC cases. Here we established that the Keap1 promoter is hypermethylated in pancreatic cancer cells. UHRF1 knockdown was accompanied by a reduction in Keap1 promoter methylation, restoration of KEAP1 protein, loss of NRF2 protein and corresponding loss of NRF2 downstream gene expression. We showed strong evidence that Keap1 expression is regulated by its promoter methylation, as KEAP1 expression was restored following 5-aza-deoxycytidine treatment. In PDAC tumour specimens (n=124), an inverse relationship between UHRF1 and KEAP1 expression was observed (p=0.002). In summary, we have shown a role for UHRF1 in pancreatic cancer growth and promoter methylation. Moreover, we have discovered an important function for UHRF1 in controlling KEAP1 expression and consequently regulating the KEAP1/NRF2 stress response pathway.

description: The economy system is mainly based on extracting raw materials to be used as inputs that altogether with tech­nology and labor will be transformed into final products that later will be sold to consumers. These products would be used through their life cycle, and will be replaced as soon as the object has accomplished its duty or a new product shows up in the market with better features, and replace the obsoletes ones. The obsolete products are thrown into landfills, or are incinerated which damages the environment not just by polluting, but by making firms require new raw materials to produce new goods (Andersen Mikael 2006). In addition, through all this cycle, some other facts are to be considered, such as the emission of pollutants when the production activities take place and when the final goods are used; such as CO2 emissions produced by cars. All of this is leading to different problems such the depletion of primary re­sources that causes economic and social problem, and the constant emission of pollutants is crucially affecting the environment…

description: We consider the distribution of normalized Frobenius traces for two families of genus 3 hyperelliptic curves over Q that have large automorphism groups: y^2=x^8+c and y^2=x^7-cx with c in Q*. We give efficient algorithms to compute the trace of Frobenius for curves in these families at primes of good reduction. Using data generated by these algorithms, we obtain a heuristic description of the Sato-Tate groups that arise, both generically and for particular values of c. We then prove that these heuristic descriptions are correct by explicitly computing the Sato-Tate groups via the correspondence between Sato-Tate groups and Galois endomorphism types.

description: Spectra of methyl cyanide were recorded to analyze interactions in low-lying vibrational states and to construct line lists for radio astronomical observations as well as for infrared spectroscopic investigations of planetary atmospheres. The rotational spectra cover large portions of the 36$-$1627 GHz region. In the infrared (IR), a spectrum was recorded for this study in the region of 2$ν_8$ around 717 cm$^{-1}$ with assignments covering 684$-$765 cm$^{-1}$. Additional spectra in the $ν_8$ region were used to validate the analysis. The large amount and the high accuracy of the rotational data extend to much higher $J$ and $K$ quantum numbers and allowed us to investigate for the first time in depth local interactions between these states which occur at high $K$ values. In particular, we have detected several interactions between $v_8 = 1$ and 2. Notably, there is a strong $Δv_8 = \pm1$, $ΔK = 0$, $Δl = \pm3$ Fermi resonance between $v_8 = 1^{-1}$ and $v_8 = 2^{+2}$ at $K$ = 14. Pronounced effects in the spectrum are also caused by resonant $Δv_8 = \pm1$, $ΔK = \mp2$, $Δl = \pm1$ interactions between $v_8 = 1$ and 2. An equivalent resonant interaction occurs between $K$ = 14 of the ground vibrational state and $K$ = 12, $l = +1$ of $v_8 = 1$ for which we present the first detailed account. A preliminary account was given in an earlier study on the ground vibrational state. From data pertaining to $v_8 = 2$, we also investigated rotational interactions with $v_4 = 1$ as well as $Δv_8 = \pm1$, $ΔK = 0$, $Δl = \pm3$ Fermi interactions between $v_8 = 2$ and 3. We have derived N$_2$- and self-broadening coefficients for the $ν_8$, 2$ν_8 - ν_8$, and 2$ν_8$ bands from previously determined nu4 values. Subsequently, we determined transition moments and intensities for the three IR bands.

title: Adverse drug reactions causing admission in children

description: Children are vulnerable to adverse drug reactions (ADRs) but have been under-represented in studies which have addressed their incidence and prevention. The aim of my thesis was to undertake a prospective study of ADR-related hospital admissions. The first step involved the development of the methodology by undertaking a prospective observational pilot study assessing all unplanned admissions over a 2 week period. There were 19 admissions to the main hospital wards related to an ADR, giving an estimated ADR incidence of 4%. Among the methodological considerations assessed in the study was the definition of what constitutes an admission (whether to include patients admitted to the Accident & Emergency observation ward), the feasibility of the data collection methods, and an assessment of the feasibility of managing the workload between three investigators. ADR causality assessment in the pilot study was undertaken using the validated Naranjo tool. However, this was found to be lacking in sensitivity, with underestimation of the likelihood of an ADR. A causality assessment tool (CAT) that would overcome some of these issues, while at the same time making it as easy, or easier, to use than the Naranjo tool was formulated by an expert focus group. We undertook a comparison of the new Liverpool CAT with the Naranjo tool using seven assessors. This showed that the Liverpool CAT assigned the full range of causality categories and showed better inter-rater reliability than Naranjo. ADRs causing paediatric hospital admission were subsequently studied over a one year period. There were 247 ADRs in 240/8345 patients admitted acutely to the hospital, giving an estimated ADR admission incidence of 2.9% (95% CI 2.5, 3.3). There were no deaths attributable to an ADR. 120/249 (48.2%) ADRs resulted from treatment for malignancies. The origin of prescription for causative drugs was assessed; prescriptions originating in the community accounted for 44/249 (17.7%) of ADRs with the remainder from hospital. Assessment of the avoidability of the ADR cases using the Liverpool CAT showed that 22.1% (95% CI 17%, 28%) of the reactions were either ‘definitely’ or ‘possibly’ avoidable. Few studies in the literature have reported specific avoidability outcomes, which is important to prioritise interventional strategies to reduce the burden of ADRs. ADRs in children are an important public health problem. Most of those serious enough to require hospital admission are due to hospital-based prescribing, of which just over a fifth may be avoidable. Strategies to reduce the burden of ill-health from these ADRs are needed.

Suppose that $b\ge d$ if $a=c$, and $d\ge f$ if $c=e$. When $b(a-b)$, $d(c-d)$ and $f(e-f)$ are not all zero, we prove that if each $n\in\mathbb N=\{0,1,2,\ldots\}$ can be written $x(ax+b)/2+y(cy+d)/2+z(ez+f)/2$ with $x,y,z\in\mathbb N$ then the tuple $(a,b,c,d,e,f)$ must be on our list of $473$ candidates, and show that 56 of them meet our purpose. When $b\in[0,a)$, $d\in[0,c)$ and $f\in[0,e)$, we investigate the universal tuples $(a,b,c,d,e,f)$ over $\mathbb Z$ for which any $n\in\mathbb N$ can be written $x(ax+b)/2+y(cy+d)/2+z(ez+f)/2$ with $x,y,z\in\mathbb Z$, and show that there are totally 12082 such candidates some of which are proved to be universal tuples over $\mathbb Z$. For example, we show that any $n\in\mathbb N$ can be written as $x(x+1)/2+y(3y+1)/2+z(5z+1)/2$ with $x,y,z\in\mathbb Z$, and conjecture that each $n\in\mathbb N$ can be written as $x(x+1)/2+y(3y+1)/2+z(5z+1)/2$ with $x,y,z\in\mathbb N$.

title: Coupling flight mechanics and CFD - numerical simulation of shipborne rotors
Creators: name: Crozon, Clément
Publisher: name: University of Liverpool Repository
Year: 2016

description: This thesis demonstrates the use of Computational Fluid Dynamics (CFD) for the simulation of manoeuvring helicopters. Results are presented for the problem of shipborne operations, for which a literature survey showed that little work has been carried out. The CFD solver HMB2 was first validated using available experimental data for isolated ship wakes and helicopter loads at low advance ratios. A rotorcraft flight mechanics model was then developed and integrated into HMB2. The model includes a trimming method and a linearisation routine based on finite differences. The linear model of the aircraft can be used to estimate the controls applied by the pilot during a prescribed manoeuvre via the use of the SYCOS inverse-simulation method or via an LQR auto-pilot. The methods developed in the framework of this thesis include a general multi-body grid motion and an alternative formulation for earth-fixed frame of reference in the CFD. A study of the ship/rotor wake interaction was carried out using the actuator disc method that approximated the effect of the rotor, in a steady fashion and without resolving the flow around the blades. Various positions and thrust of the rotor were tested and the flowfield obtained via coupled simulations were compared with those obtained by super-imposing isolated rotor and ship flowfields. The results show that the superposition principle is not valid and leads to flowfields that have little to do with the real flow that is dominated by the interaction of helicopter and ship airwakes. The case of a rotor hovering in close proximity to a frigate deck was reproduced with fullyresolved blades, and the results shows a significant reduction of thrust due to the flow topology behind the hangar. The Helicopter Flight Mechanics (HFM) method was tested by simulating the aircraft response to a collective pilot input, using simplified models and coupled with CFD. Then, the coupled HFM/HMB2 method was used, in conjunction with the LQR auto-pilot, to simulate the phase of landing of a Sea King helicopter. Simulations were carried-out in free-air and above the frigate deck and the specified trajectories were followed adequately. Results for the ship landing show that the wake of the ship alters the obtained landing trajectory and that the current method captures some of the effects of the wake interaction.

description: Background: Limited information is available for patients with breast cancer (BC) and coronavirus disease 2019 (COVID-19), especially among underrepresented racial/ethnic populations. Methods: This is a COVID-19 and Cancer Consortium (CCC19) registry-based retrospective cohort study of females with active or history of BC and laboratory-confirmed severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection diagnosed between March 2020 and June 2021 in the US. Primary outcome was COVID-19 severity measured on a five-level ordinal scale, including none of the following complications, hospitalization, intensive care unit admission, mechanical ventilation, and all-cause mortality. Multivariable ordinal logistic regression model identified characteristics associated with COVID-19 severity. Results: 1,383 female patient records with BC and COVID-19 were included in the analysis, the median age was 61 years, and median follow-up was 90 days. Multivariable analysis revealed higher odds of COVID-19 severity for older age (aOR per decade, 1.48 [95% CI, 1.32–1.67]); Black patients (aOR 1.74; 95 CI 1.24–2.45), Asian Americans and Pacific Islander patients (aOR 3.40; 95 CI 1.70–6.79) and Other (aOR 2.97; 95 CI 1.71–5.17) racial/ethnic groups; worse ECOG performance status (ECOG PS ≥2: aOR, 7.78 [95% CI, 4.83–12.5]); pre-existing cardiovascular (aOR, 2.26 [95% CI, 1.63–3.15])/pulmonary comorbidities (aOR, 1.65 [95% CI, 1.20–2.29]); diabetes mellitus (aOR, 2.25 [95% CI, 1.66–3.04]); and active and progressing cancer (aOR, 12.5 [95% CI, 6.89–22.6]). Hispanic ethnicity, timing, and type of anti-cancer therapy modalities were not significantly associated with worse COVID-19 outcomes. The total all-cause mortality and hospitalization rate for the entire cohort were 9% and 37%, respectively; however, it varied according to the BC disease status. Conclusions: Using one of the largest registries on cancer and COVID-19, we identified patient- and BC-related factors associated with worse COVID-19 outcomes. After adjusting for baseline characteristics, underrepresented racial/ethnic patients experienced worse outcomes compared to Non-Hispanic White patients.
title: Women's experiences of sexual intimacy In the early postnatal period following physical birth trauma
Creators: name: Stephenson, Rebecca
Publisher: name: University of Liverpool Repository

description: Background: Sexual relations are fundamental to physical and emotional well-being. The present study aimed to explore women’s experiences of sexual intimacy in the early postnatal period following physical birth trauma (defined as either a second-degree tear or an episiotomy), considering any sexual intimacy difficulties and their reasons for and/or barriers to seeking support for these. Method: Individual semi-structured interviews were conducted with five participants, and analysed using Interpretative Phenomenological Analysis (IPA). Results: Five master themes captured the women’s experiences; ‘Identity struggle: The old ‘normal’ versus accepting a new normal’, ‘Intimacy losses versus intimacy gains’, ‘The silent struggle’, ‘Change in relational identity: Transitioning from sexual to parental’ and ‘The missing chapter of the postnatal story’. Conclusion: The accounts uncovered how the women’s bodies, identities and lives had been physically, emotionally and sexually transformed, from a sexual dyad to a parental triad. Their hidden fears of sex causing pain and trauma remained unexpressed and unanswered, due to the absence of postnatal discussions, and a void of information on sexual intimacy or the consequences of physical birth trauma. The clinical implications are discussed with regards to supporting health care professionals to initiate such discussions, through delivering training, consultation, supervision and service evaluations.

description: The paper discusses the gate complexity of reversible circuits consisting of NOT, CNOT and 2-CNOT gates. The Shannon gate complexity function $L(n, q)$ for a reversible circuit, implementing a Boolean transformation $f\colon \mathbb Z_2^n \to \mathbb Z_2^n$, is defined as a function of $n$ and the number of additional inputs $q$. The general lower bound $L(n,q) \geq \frac{2^n(n-2)}{3\log_2(n+q)} - \frac{n}{3}$ for the gate complexity of a reversible circuit is proved. An upper bound $L(n,0) \leqslant 3n2^{n+4}(1+o(1)) \mathop / \log_2n$ for the gate complexity of a reversible circuit without additional inputs is proved. An upper bound $L(n,q_0) \lesssim 2^n$ for the gate complexity of a reversible circuit with $q_0 \sim n2^{n-o(n)}$ additional inputs is proved.

title: Porous organic cages: synthesis and application in noble gas separation
Creators: name: Reiss, Paul
Publisher: name: University of Liverpool Repository

description: Porous organic cages have recently received much attention due to their synthetic tunability, solution processability, high gas adsorption capacities, and ability to selectively separate small molecules based on their size and shape. In this thesis, a range of novel porous organic cages are presented, with each possessing unique functionalities, pore structures and gas sorption properties due to the employment of synthetically-modified versions of traditional trialdehyde and diamine cage precursors. The introduction of new functionality into the cage structure, including methyl, hydroxyl and ethanoanthracene groups, highlights how subtle modification of the cage precursors can initiate significant changes in the self-assembly of the cage molecules. This in turn affects the pore dimensions, as well as the gas sorption and separation performance, of the resultant porous material. This strategy led to the successful isolation of an asymmetric cage molecule, which demonstrated the potential to separate noble gases, as well as the preparation of cages with diverse vertex functionality, molecular size and gas sorption properties. The ability of porous organic cages to selectively separate xenon from krypton gas was also investigated through the use of dynamic breakthrough measurements, with the performance of these cages surpassing all other porous materials evaluated to date.

description: The future of quantum communication relies on quantum networks composed by observers sharing multipartite quantum states. The certification of multipartite entanglement will be crucial to the usefulness of these networks. In many real situations it is natural to assume that some observers are more trusted than others in the sense that they have more knowledge of their measurement apparatuses. Here we propose a general method to certify all kinds of multipartite entanglement in this asymmetric scenario and experimentally demonstrate it in an optical experiment. Our results, which can be seen as a definition of genuine multipartite quantum steering, give a method to detect entanglement in a scenario in between the standard entanglement and fully device-independent scenarios, and provide a basis for semi-device-independent cryptographic applications in quantum networks.

title: Developing and testing an integrative model of binge drinking behaviour in a student population
Creators: name: Bettney, Laura
Publisher: name: University of Liverpool Repository

description: Binge drinking (BD) is a pressing social and public health concern in the United Kingdom, especially among university students. Several psychological constructs have been associated with BD behaviour in student populations, including adult attachment style, dispositional mindfulness (DM), alcohol expectancies, and approach motivations. However, as yet, there has been little attempt to study these constructs together in a theoretically-coherent model, which the current study aimed to do. Three hundred and twenty-two students at a UK university in north-west England completed an online questionnaire to assess their drinking behaviour and the psychological constructs of interest. Structural equation modelling results supported a model whereby preoccupied and fearful insecure adult attachment styles predicted an affect-regulation strategy characterised by an inability to be ‘non-judgmental’ towards, and to ‘act with awareness’ in relation to internal and external experiences (elements of DM), and lower levels of these DM variables in turn were associated with positive expectancies about the consequences of alcohol use. Strong positive expectancies about drinking alcohol were related to the presence of strong approach motivations towards drinking, which in turn predicted increased BD behaviour. The results are supportive of the proposed integrated model of BD behaviour in students. The model helps to highlights areas where harm-reduction and intervention strategies aimed at reducing BD in students can be targeted.

description: Abstract
We theoretically study the structural stability, elastic and electronic properties of the transition metal mono nitride and mono carbide compounds (TMN's and TMC's) by using the full-potential linear muffin-tin orbital (FP-LMTO) method, in the framework of the density functional theory (DFT) within the local density approximation (LDA) for the exchange correlation functionals. The equilibrium ground state of properties including lattice parameters, bulk modulus and its pressure derivatives for the six considered crystal structures, Rock-salt (B1),CsCl (B2), zinc-blend (B3) , Wûrtzite (B4), NiAs (B81) and the tungsten carbides (Bh) were calculated. The elastic constants of TMN's and TMC's in its different stable phases are determined by using the total energy variation with strain technique. The elastic moduli for polycrystalline materials, such as the shear modulus (G), Young's modulus (E), and Poisson's ratio (ν) were estimated. The Debye temperature (θD) and Sound velocities (vm) were also derived from the obtained elastic moduli. In the objective to propose a new Superhard materials in TMN's and TMC's, the analysis of the hardness classified IrN (B3), OsN (B4 and B81), ReN (B81), WN (B81) and OsC (B81) as Superhard materials. Our results for the band structure and the density of states (DOS), show that TMN's and TMC's in its more stable phase have the metallic characteristic with strong covalent nature Metal-Non Metal elements. It is our ambition that these calculations will inspire further experimental research on these compounds.
title: Modelling financial markets using methods from network theory.
Creators: name: Birch, Jenna
Publisher: name: University of Liverpool Repository
Year: 2016

description: This thesis discusses how properties of complex network theory can be used to study financial time series, in particular time series for stocks on the DAX 30. First, we make a comparison between three correlation-based networks: minimum spanning trees; assets graphs and planar maximally filtered graphs. A series of each of these network types is created for the same dataset of time series' of DAX 30 stocks and we consider what information each network can provide about the relationship between the stock prices from the underlying time series. We also analyse two specific time periods in further detail - a period of crisis and a period of recovery for the German economy. Next, we look at the structure and representations of planar maximally filtered graphs and in particular we consider the vertices that form the 3-cliques and 4-cliques [Tumminello et al. (2005)] state '...normalizing quantities are n_s - 3 for 4-cliques and 3n_s - 8 for 3-cliques. Although we lack a formal proof, our investigations suggest that these numbers are the maximal number of 4-cliques and 3-cliques, respectively, that can be observed in a PMFG of n_s elements.' Within this thesis we provide a proof for these quantities and a different construction algorithm. Finally, rather than correlation-based networks, we discuss two relatively new types of networks: visibility graphs and the geometrically simpler horizontal visibility graphs. We review the field's that these networks have already been applied to and consider if this is an appropriate method to apply to financial time series - specifically stock prices. We also consider using horizontal visibility graphs as a method for distinguishing between random and chaotic series within stock price time series.
title: Service user experiences of the sequential diagrammatic reformulation (SDR) in cognitive analytical therapy (CAT): an interpretative phenomenological analysis.
Creators: name: Taplin, Kimberley
Publisher: name: University of Liverpool Repository
Year: 2016

description: This thesis is organised into two chapters: a systematic review; an empirical research paper; and relevant appendices. Each chapter is presented as a standalone component adding to current gaps in the literature. Chapter 1 presents a systematic literature review of all current research aiming to understand service-users’ views of psychological formulation. A total of 297 studies were initially retrieved. 11 papers were included in the final review. A narrative synthesis of their findings is presented. The literature suggests several common themes include: responses to formulation; biopsychosocial understanding; practicable and tangible; collaboration; therapeutic relationship; process; communication; change and diagnostic symptoms. Clinical implications, gaps in knowledge and the need for further research are discussed. Chapter 2 extends the research discussed in the systematic review with a qualitative empirical paper exploring service-users experiences of the SDR. Interpretative Phenomenological Analysis (IPA) was used to explore/analyse the data. Four superordinate themes emerged from the data: ‘Chaos to clarity (a process of meaning making)’; ‘The change process’; ‘Relational dynamics’; and ‘Focus on treatment context/options’. Findings are consistent with, and extend, the current literature on CAT and formulation. Strengths and weaknesses of this research, future research ideas and clinical implications at an individual therapy and service/organisational level are discussed.

title: Die Wahrnehmung von "Ostjuden" in drei Wiener jüdischen Zeitungen von 1914 bis 1920
Creators: name: Lechner, Klara
Year: 2022

description: In dieser Masterarbeit wird untersucht, wie sogenannte „Ostjuden“ in drei jüdischen Zeitungen wahrgenommen wurden, die in Wien erschienen waren. Die drei jüdischen Zeitungen „Die Wahrheit“, die „Jüdische Korrespondenz“ und die „Jüdische Volksstimme“ sind der Fokus der Analyse, da sie mit ihrer Blattlinie drei unterschiedliche relevante Strömungen innerhalb des Judentums vertraten und dies eine differenzierte Betrachtung erlaubte. Der zeitliche Rahmen ist dabei von Beginn des Jahres 1914 bis zum Ende des Jahres 1920 gewählt, da dies von Wien ausgesehen eine Phase von intensiver Auseinandersetzung mit „Ostjuden“ war. Um die Fragestellung zu klären, wurden die Quellen mittels der inhaltlich-strukturierenden qualitativen Inhaltsanalyse nach Mayring erarbeitet. Dabei entstanden verschiedene thematische Kategorien, in deren Kontext zu „Ostjuden“ publiziert wurde. Sie waren je nach Zeitung und Jahr der Analyse unterschiedlich häufig vorzufinden, was stark mit dem Verlauf des Ersten Weltkrieges zusammenhing. Es filterten sich zusätzlich fünf Kategorien von Wahrnehmungen heraus: bemitleidenswert, hilfsbedürftig, positiv, negativ und sachlich-informativ. Dabei häufte sich vor allem die Wahrnehmung von „Ostjuden“ als bemitleidenswert, wenngleich hier auch Unterschiede je nach Blattlinie und Jahr der Analyse sichtbar wurden.

Motivation

description: Das Ziel dieser Arbeit ist es zu beantworten, ob durch handlungsorientierten Unterricht die Motivation der SuS gesteigert werden kann. Dazu wird die folgende Forschungsfrage gestellt: "Inwiefern kann handlungsorientierter Mathematikunterricht für Schülerinnen und Schüler mit Förderbedarf motivierend wirken?" Um diese Forschungsfrage zu beantworten, wurde eine Handlungsforschung mit vier Schüler:innen einer vierten Klasse durchgeführt. Neben der teilnehmenden Beobachtung wurden Fragebögen, Kompetenztests und Selbstbeurteilungsbögen eingesetzt. Die Forschungsergebnisse zeigten auf, dass ein handlungsorientierter Unterricht durchaus motivationsfördernd wirken kann. Die Implementierung der in der Literatur vorgeschlagenen Handlungssituationen war jedoch nicht immer einfach. Es wurde ersichtlich, dass jede zu integrierende Handlungssituation sowohl Stärken wie auch Schwächen besitzt. Weiter stellte sich heraus, dass die Handlungssituationen unterschiedlich motivationsfördernd wirkten.
