description: To ascertain whether photometric decompositions of galaxies into bulges and disks are astrophysically meaningful, we have developed a new technique to decompose spectral data cubes into separate bulge and disk components, subject only to the constraint that they reproduce the conventional photometric decomposition. These decompositions allow us to study the kinematic and stellar population properties of the individual components and how they vary with position, in order to assess their plausibility as discrete elements, and to start to reconstruct their distinct formation histories. An initial application of this method to CALIFA integral field unit observations of three isolated S0 galaxies confirms that in regions where both bulge and disc contribute significantly to the flux they can be physically and robustly decomposed into a rotating dispersion-dominated bulge component, and a rotating low-dispersion disc component. Analysis of the resulting stellar populations shows that the bulges of these galaxies have a range of ages relative to their discs, indicating that a variety of processes are necessary to describe their evolution. This simple test case indicates the broad potential for extracting from spectral data cubes the full spectral data of a wide variety of individual galaxy components, and for using such decompositions to understand the interplay between these various structures, and hence how such systems formed.

description: The core of this work is an old and broadly discussed problem of the electromagnetic radiation in the case of the hyperbolic motion. We prove that the radiation is non-zero in the lab (Minkowski) frame. Further, we attempt to understand this subject better by using co-moving non-inertial frames of reference, investigating other types of uniformly accelerated motion and, finally, using scalar waves instead of point-like particles as sources of radiation.

description: In 1973, E.J. McShane proposed an alternative definition of the Lebesgue integral based on Riemann sums, where gauges are used decide what tagged partitions are allowed. Such an approach does not require any preliminary knowledge of Measure theory. We investigate in this paper a definition of measurable functions also based on gauges. Its relation to the gauge-integrable functions that satisfy McShane's definition is obtained using elementary tools from Real Analysis. We show in particular a dominated integration property of gauge-measurable functions.

description: We present SCUBA-2 follow-up of 61 candidate high-redshift Planck sources. Of these, 10 are confirmed strong gravitational lenses and comprise some of the brightest such submm sources on the observed sky, while 51 are candidate proto-cluster fields undergoing massive starburst events. With the accompanying Herschel-SPIRE observations and assuming an empirical dust temperature prior of $34^{+13}_{-9}$ K, we provide photometric redshift and far-IR luminosity estimates for 172 SCUBA-2-selected sources within these Planck overdensity fields. The redshift distribution of the sources peak between a redshift of 2 and 4, with one third of the sources having $S_{500}$/$S_{350} > 1$. For the majority of the sources, we find far-IR luminosities of approximately $10^{13}\,\mathrm{L}_\odot$, corresponding to star-formation rates of around $1000$ M$_\odot \mathrm{yr}^{-1}$. For $S_{850}>8$ mJy sources, we show that there is up to an order of magnitude increase in star-formation rate density and an increase in uncorrected number counts of $6$ for $S_{850}>8$ mJy when compared to typical cosmological survey fields. The sources detected with SCUBA-2 account for only approximately $5$ per cent of the Planck flux at 353 GHz, and thus many more fainter sources are expected in these fields.

description: Previous studies indicate that compound Danshen Dripping Pill (CDDP) improves the adaptation to high-altitude exposure. However, its mechanism of action is not clear. To explore the protective effect of CDDP on hypobaric hypoxia (HH) and its possible mechanism. A meta-analysis of 1051 human volunteers was performed to evaluate the effectiveness of CDDP at high altitudes. Male Sprague-Dawley rats were randomized into 5 groups (n = 6): control at normal pressure, model, CDDP-170 mg/kg, CDDP-340 mg/kg and acetazolamide groups. HH was simulated at an altitude of 5500 m for 24 h. Animal blood was collected for arterial blood-gas analysis and cytokines detection and their organs were harvested for pathological examination. Expression levels of AQP1, NF-κB and Nrf2 were determined by immunohistochemical staining. The meta-analysis data indicated that the ratio between the combined RR of the total effective rate and the 95% CI was 0.23 (0.06, 0.91), the SMD and 95% CI of SO2 was 0.37 (0.12, 0.62). Pre-treatment of CDDP protected rats from HH-induced pulmonary edoema and heart injury, left-shifted oxygen-dissociation curve and decreased P50 (30.25 ± 3.72 vs. 37.23 ± 4.30). Mechanistically, CDDP alleviated HH-reinforced ROS by improving SOD and GPX1 while inhibiting pro-inflammatory cytokines and NF-κB expression. CDDP also decreased HH-evoked D-dimer, erythrocyte aggregation and blood hemorheology, promoting AQP1 and Nrf2 expression. Pre-treatment with CDDP could prevent HH-induced tissue damage, oxidative stress and inflammatory response. Suppressed NF-κB and up-regulated Nrf2 might play significant roles in the mechanism of CDDP.

Sedentary behaviour and spinal pain in adolescents

Publisher: name: Macquarie University

description: Spinal pain in adolescents is a significant public health concern, and adolescent sedentary behaviour is a proposed modifiable risk factor for spinal pain. Whether sedentary behaviour recommendations in international public health guidelines are relevant for adolescent spinal pain is unknown. This thesis reports a systematic review exploring associations between sedentary behaviours and spinal pain in adolescents. It also reports a secondary cross-sectional analysis, of a population-based cohort of young adolescent Danes, to investigate the association between sedentary behaviour (as per public health guidelines) and non-trivial spinal pain. Cross-sectional multinominal logistic regression investigated associations between sedentary behaviour, by duration and type, and spinal pain, by region and triviality, adjusted for age and sex. The systematic review found there was no meaningful association between sedentary behaviour and adolescent spinal pain; however, the evidence base is inconsistent and at high risk of bias. The cross-sectional analysis demonstrated there was no association between exceeding two hours per day of sedentary behaviour and spinal pain. The collective thesis findings suggest that sedentary behaviour is not a meaningful risk factor for adolescent back pain. Therefore, we challenge existing public and clinical beliefs that sedentary behaviour is causally associated with spinal pain in adolescents.

description: PurposeThe purpose of this study is to systematically review the current literature on the post-treatment survivorship experiences of African-American men with prostate cancer by exploring qualitative studies to gain a deep understanding of their survivorship experiences.MethodWe searched five databases for studies published from 2008 to 2018. We identified ten relevant qualitative studies, conducted a meta-synthesis using Noblit and Hare's meta-ethnography approach, and evaluated their quality appraisal using the validated Critical Appraisal Skills Program.ResultsThis review generated a total of four main themes and nine subthemes. The Four main themes included coping strategy, psychophysical impact, health system influence, and socioeconomic impact. Spirituality, healthy behaviors, supportive care of spouse/family/friends and non-communicating/reticent were subthemes identified in the coping strategy theme; physical well-being and sexuality and masculinity were subthemes in the psychophysical impact theme; healthcare provider interaction and treatment decision-making were subthemes identified in the health system influence theme, and health insurance status was the subtheme in the socioeconomic impact theme.ConclusionOur findings reveal that the experiences of African-American prostate cancer survivors are complex and multidimensional.Implications for cancer survivorsThis review highlights the need for further studies with African-American prostate cancer survivors, precisely identify their needs and plan a culturally appropriate intervention to meet those needs.

description: A finite element methodology for large classes of variational boundary value problems is defined which involves discretizing two linear operators: (1) the differential operator defining the spatial boundary value problem; and (2) a Riesz map on the test space. The resulting linear system is overdetermined. Two different approaches for solving the system are suggested (although others are discussed): (1) solving the associated normal equation with linear solvers for symmetric positive-definite systems (e.g. Cholesky factorization); and (2) solving the overdetermined system with orthogonalization algorithms (e.g. QR factorization). The finite element assembly algorithm for each of these approaches is described in detail. The normal equation approach is usually faster for direct solvers and requires less storage. The second approach reduces the condition number of the system by a power of two and is less sensitive to round-off error. The rectangular stiffness matrix of second approach is demonstrated to have condition number $\mathcal{O}(h^{-1})$ for a variety of formulations of Poisson's equation. The stiffness matrix from the normal equation approach is demonstrated to be related to the monolithic stiffness matrices of least-squares finite element methods and it is proved that the two are identical in some cases. An example with Poisson's equation indicates that the solutions of these two different linear systems can be nearly indistinguishable (if round-off error is not an issue) and rapidly converge to each other. The orthogonalization approach is suggested to be beneficial for problems which induce poorly conditioned linear systems. Experiments with Poisson's equation in single-precision arithmetic as well as the linear acoustics problem near resonance in double-precision arithmetic verify this conclusion.

description: The human brain is not only efficiently but also "redundantly" connected. The redundancy design could help the brain maintain resilience to disease attacks. This paper explores subnetwork-level redundancy dynamics and the potential of such metrics in disease studies. As such, we looked into specific functional subnetworks, including those associated with high-level functions. We investigated how the subnetwork redundancy dynamics change along with Alzheimer's disease (AD) progression and with major depressive disorder (MDD), two major disorders that could share similar subnetwork alterations. We found an increased dynamic redundancy of the subcortical-cerebellum subnetwork and its connections to other high-order subnetworks in the mild cognitive impairment (MCI) and AD compared to the normal control (NC). With gained spatial specificity, we found such a redundancy index was sensitive to disease symptoms and could act as a protective mechanism to prevent the collapse of the brain network and functions. The dynamic redundancy of the medial frontal subnetwork and its connections to the frontoparietal subnetwork was also found decreased in MDD compared to NC. The spatial specificity of the redundancy dynamics changes may provide essential knowledge for a better understanding of shared neural substrates in AD and MDD.

description: In this paper we demonstrate that using a mathematical physics approach (focusing the attention to the physics and using mathematics as a tool) it is possible to visualize the formation of the transverse modes inside a cylindrical waveguide. In opposition, the physical mathematics solutions (looking at the mathematical problem and then trying to impose a physical interpretation), when studying cylindrical waveguides yields to the Bessel differential equation and then it is argued that in the core are only the Bessel functions of the first kind those who describe the transverse modes. And the Neumann functions are deemed non physical due to its singularity at the origin and eliminated from the final description of the solution. In this paper we show, using a geometrical-wave optics approach, that the inclusion of this function is physically necessary to describe fully and properly the formation of the propagating transverse modes. Also, the field in the outside of a dielectric waveguide arises in a natural way.

description: Abstract The study investigated comparative effects of collaborative concept mapping and concept mapping instructional strategies on students’ achievement and retention in redox reactions. A sample of 142 students from 4 purposively selected secondary schools out of a population of 4,421 Senior Secondary II students from Makurdi Local Government Area of Benue State, Nigeria was used for the study. The study adopted quasi experimental research design. The instrument used for data collection was Redox Reactions Achievement Test (RRAT) with the reliability value of 0.83 using Kuder-Richardson (KR-21). Two research questions and two null hypotheses guided the study. The research questions were answered using Mean and Standard Deviation scores while the hypotheses were tested using Analysis of Covariance (ANCOVA). The study revealed that students taught redox reactions using Collaborative Concept Mapping Instructional Strategy (CCMIS) had significantly higher mean achievement scores than those taught using Concept Mapping Instructional Strategy (CMIS) [F(1, 141)= 437.438, P<0.05] and students taught redox reactions using CCMIS had significantly higher mean retention scores than those taught using CMIS[F(1, 141)= 204.142, P<0.05]. It was recommended among others that chemistry teacher trainees should be trained on the use of CCMIS and serving teachers should be encouraged to use CCMIS.

description: Graph theory has been extensively used to investigate brain network topology and its changes in disease cohorts. However, many graph theoretic analysis-based brain network studies focused on the shortest paths or, more generally, cost-efficiency. In this work, we use two new concepts, connectedness and 2-connectedness, to measure different global properties compared to the previously widely adopted ones. We apply them to unravel interesting characteristics in the brain, such as redundancy design and further conduct a time-varying brain functional network analysis for characterizing the progression of Alzheimer's disease (AD). Specifically, we define different connectedness and 2-connectedness states and evaluate their dynamics in AD and its preclinical stage, mild cognitive impairment (MCI), compared to the normal controls (NC). Results indicate that, compared to MCI and NC, brain networks of AD tend to be more frequently connected at a sparse level. For MCI, we found that their brains are more likely to be 2-connected in the minimal connected state as well indicating increasing redundancy in brain connectivity. Such a redundant design could ensure maintained connectedness of the MCI's brain network in the case that pathological damages break down any link or silenced any node, making it possible to preserve cognitive abilities. Our study suggests that the redundancy in the brain functional chronnectome could be altered in the preclinical stage of AD. The findings can be successfully replicated in a retest study and with an independent MCI dataset. Characterizing redundancy design in the brain chronnectome using connectedness and 2-connectedness analysis provides a unique viewpoint for understanding disease affected brain networks.

description: The 2023 Nobel-prize was awarded for work which pushed the field of ultrafast atomic physics into the attosecond (10-18s) timescale. However, simulating ultrafast atomic interactions poses a significant challenge. Simple models often neglect important processes, while more accurate approaches tend to be restricted to specific laser regimes or targets.  While a general approach would require fully describing the multielectron dynamics of the system, extending that description to a large spatial region is prohibitively computationally expensive. The R-Matrix with Time-Dependence(RMT) code achieves the required performance using an R-Matrix space segmentation to provide a simpler description far from the atom while taking advantage of the full, multielectron description close to the atom, as well as using multiple MPI parallelisation schemes and OpenMP parallelism. With such a general model, RMT can not only provide insights into experimental findings but also guide the direction of future experimental work.

In recent years there are two key areas in which RMT has been used to further the field: light-atom interactions in the perturbative regime, and laser-atom interactions in the strong-field regime. The perturbative regime is particularly important in understanding how atomic structure affects interactions. However, perturbative models neglect many atomic processes by necessity, whereas RMT can provide vital information about the effects of non-perturbative processes in and near that regime. On the other hand, strong field ionisation is central to our understanding of quantum phenomena like tunnelling, and RMT’s full description of electron dynamics, alongside the detailed atomic structure it can use, provides novel insights.

description: Variability (and extremes) in streamflow, wind speeds, temperatures, and solar irradiance influence supply and demand for electricity. However, previous research falls short in addressing the risks that joint uncertainties in these processes pose in power systems and wholesale electricity markets. Limiting challenges have included the large areal extents of power systems, high temporal resolutions (hourly or sub-hourly), and the data volumes and computational intensities required. This paper introduces an open source modeling framework for evaluating risks from correlated hydrometeorological processes in electricity markets at decision relevant scales. The framework is able to reproduce historical price dynamics in high profile systems, while also offering unique capabilities for stochastic simulation. Synthetic generation of weather and hydrologic variables is coupled with simulation models of relevant infrastructure (dams, power plants). Our model will allow the role of hydrometeorological uncertainty (including compound extreme events) on electricity market outcomes to be explored using publicly available models.

description: The estimation of high order correlation function values is an important problem in the field of quantum computation. We show that the problem can be reduced to preparation and measurement of optical quantum states resulting after annihilation of a set number of quanta from the original beam. We apply this approach to explore various photon bunching regimes in optical states with gamma-compounded Poisson photon number statistics. We prepare and perform measurement of the thermal quantum state as well as states produced by subtracting one to ten photons from it. Maximum likelihood estimation is employed for parameter estimation. The goal of this research is the development of highly accurate procedures for generation and quality control of optical quantum states.

description: Diffusion MRI requires sufficient coverage of the diffusion wavevector space, also known as the q-space, to adequately capture the pattern of water diffusion in various directions and scales. As a result, the acquisition time can be prohibitive for individuals who are unable to stay still in the scanner for an extensive period of time, such as infants. To address this problem, in this paper we harness non-local self-similar information in the x-q space of diffusion MRI data for q-space upsampling. Specifically, we first perform neighborhood matching to establish the relationships of signals in x-q space. The signal relationships are then used to regularize an ill-posed inverse problem related to the estimation of high angular resolution diffusion MRI data from its low-resolution counterpart. Our framework allows information from curved white matter structures to be used for effective regularization of the otherwise ill-posed problem. Extensive evaluations using synthetic and infant diffusion MRI data demonstrate the effectiveness of our method. Compared with the widely adopted interpolation methods using spherical radial basis functions and spherical harmonics, our method is able to produce high angular resolution diffusion MRI data with greater quality, both qualitatively and quantitatively.

Judaic and Christian divergence in renewal: apocalyptic indicators from the revelation of John
Creators: name: Peacock, John W.
Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: Evident in the variety of Second Temple Judaisms are significant elements of renewal and diversification, emerging from the foundations of Judaic tradition and the Hebrew scriptures. Thus, continuity and renewal are features of the Judaic context from which Christianity emerged and to which it remained tethered through the first century. From such a context arise issues of Judaic-Christian divergence and modern metaphors deployed to suggest a definitive parting or partings. Such metaphors are argued to be modern theological constructs which do not portray the complexities involved in first-century issues of religious renewal and divergence. To explore issues of Judaic-Christian divergence, the motifs of the temple and the new Jerusalem, the priesthood, and the temple, expressed in the Apocalypse of John, are analysed in the context of non-binary first-century, Jewish and Jewish-Christian, apocalyptic writings. This discussion, identifying less-discussed motifs in the Apocalypse of John, constitutes in Part 2 the main focus of the thesis. The conclusion is drawn that, at the close of the first century of the Common Era, such motifs in John’s Apocalypse serve as indicators of Judaic-Christian divergence in renewal, rather than bifurcation.

description: Histone H3 lysine 36 methylation (H3K36me) is a conserved histone modification associated with transcription and DNA repair. Although the effects of H3K36 methylation have been studied, the genome-wide dynamics of H3K36me deposition and removal are not known. We established rapid and reversible optogenetic control for Set2, the sole H3K36 methyltransferase in yeast, by fusing the enzyme with the light-activated nuclear shuttle (LANS) domain. Light activation resulted in efficient Set2-LANS nuclear localization followed by H3K36me3 deposition in vivo, with total H3K36me3 levels correlating with RNA abundance. Although genes showed disparate levels of H3K36 methylation, relative rates of H3K36me3 accumulation were largely linear and consistent across genes, suggesting that H3K36me3 deposition occurs in a directed fashion on all transcribed genes regardless of their overall transcription frequency. Removal of H3K36me3 was highly dependent on the demethylase Rph1. However, the per-gene rate of H3K36me3 loss weakly correlated with RNA abundance and followed exponential decay, suggesting H3K36 demethylases act in a global, stochastic manner. Altogether, these data provide a detailed temporal view of H3K36 methylation and demethylation that suggests transcription-dependent and -independent mechanisms for H3K36me deposition and removal, respectively.

description: Sky subtraction is the key technique in data reduction of multi-fiber spectra. Knowledge of the related instrument character is necessary to determine the method adopted in sky subtraction. In this study, we described the sky subtraction method designed for LAMOST(Large sky Area Multi-Object fiber Spectroscopic Telescope) survey. The method has been intergrated into LAMOST 2D Pipeline v2.6 and applied to data of LAMOST DR3 and later. For LAMOST, sky emission line calibration is used to alleviate the position-dependent (thus time-dependent) ~4% fiber throughput uncertainty and the small wavelength instability (0.1Å) during observation. PCA (Principal Component Analysis) sky subtraction further reduces 25% of the sky line residual of the OH lines in the red part of the LAMOST spectra after the mater sky spectrum, which is derived from a B-spline fit of 20 sky fibers in each spectrograph, is adjusted by sky emission line and subtracted from each fiber. Further analysis shows that our wavelength calibration accuracy is about 4.5km/s, and the average sky subtraction residuals are about 3% for sky emission lines and 3% for continuum region. The relative sky subtraction residuals vary with the moon light background brightness, could reach as low as 1.5% for the sky emission line regions in the dark night. Tests on the F stars of both similar sky emission line strength and similar object continuum intensity show that the sky emission line residual of LAMOST is smaller than those of SDSS survey.

description: Current medicine for Alzheimer’s disease (AD) cannot effectively reverse or block nerve injury. Traditional Chinese Medicine practice and research imply Aconiti lateralis Radix Praeparata (Fuzi) may meet this goal. Analysing the anti-AD effect of Fuzi and its potential molecular mechanism. AD model cells were treated with Fuzi in 0-300 mg/mL for 24 h in 37 °C. The cell viability (CV) and length of cell projections (LCP) for each group were observed, analysed, and standardised using control as a baseline (CVs and LCPs). The Fuzi and AD relevant genes were identified basing on databases, and the molecular mechanism of Fuzi anti-AD was predicted by network analysis. Experiment results showed that Fuzi in 0.4 mg/mL boosted LCP (LCPs = 1.2533, p ≤ 0.05), and in 1.6–100 mg/mL increased CV (CVs from 1.1673 to 1.3321, p ≤ 0.05). Bioinformatics analysis found 17 Fuzi target genes (relevant scores ≥ 20), showing strong AD relevant signals (RMS_p ≤ 0.05, related scores ≥ 5), enriched in the pathways regulating axon growth, synaptic plasticity, cell survival, proliferation, apoptosis, and death (p ≤ 0.05). Especially, GRIN1 and MAPK1 interacted with APP protein and located in the key point of the “Alzheimer’s disease” pathway. These results suggest that Fuzi may have therapeutic and prevention potential in AD, and GRIN1 and MAPK1 may be the core of the pathways of the Fuzi anti-AD process. Fuzi should be studied more extensively, especially for the prevention of AD.

description: A Bayesian model of the emission spectrum of the JET lithium beam has been developed to infer the intensity of the Li I (2p-2s) line radiation and associated uncertainties. The detected spectrum for each channel of the lithium beam emission spectroscopy (Li-BES) system is here modelled by a single Li line modified by an instrumental function, Bremsstrahlung background, instrumental offset, and interference filter curve. Both the instrumental function and the interference filter curve are modelled with non-parametric Gaussian processes. All free parameters of the model, the intensities of the Li line, Bremsstrahlung background, and instrumental offset, are inferred using Bayesian probability theory with a Gaussian likelihood for photon statistics and electronic background noise. The prior distributions of the free parameters are chosen as Gaussians. Given these assumptions, the intensity of the Li line and corresponding uncertainties are analytically available using a Bayesian linear inversion technique. The proposed approach makes it possible to extract the intensity of Li line without doing a separate background subtraction through modulation of the Li beam.

description: In the current analysis plan, we propose to explore associations of pregnancy metabolic profiles quantified by Nuclear Magnetic Resonance (NMR) and the risk of congenital heart diseases (CHDs) in the offspring. This could help us identify biological pathways associated with CHDs and improve our understanding of the underlying pathogenesis of the condition(s). We have access to pregnancy NMR data from two large European birth cohorts from different regions which will allow us to explore replication. We will also look for genetic evidence in multiple independent cohorts to support observational results. This involves building genetic risk scores for metabolic traits using data from the largest metabolomics genome-wide association study (GWAS) and exploring associations between the risk score and CHDs.

description: Abstract The study investigated comparative effects of collaborative concept mapping and concept mapping instructional strategies on students’ achievement and retention in redox reactions. A sample of 142 students from 4 purposively selected secondary schools out of a population of 4,421 Senior Secondary II students from Makurdi Local Government Area of Benue State, Nigeria was used for the study. The study adopted quasi experimental research design. The instrument used for data collection was Redox Reactions Achievement Test (RRAT) with the reliability value of 0.83 using Kuder-Richardson (KR-21). Two research questions and two null hypotheses guided the study. The research questions were answered using Mean and Standard Deviation scores while the hypotheses were tested using Analysis of Covariance (ANCOVA). The study revealed that students taught redox reactions using Collaborative Concept Mapping Instructional Strategy (CCMIS) had significantly higher mean achievement scores than those taught using Concept Mapping Instructional Strategy (CMIS) [F(1, 141)= 437.438, P<0.05] and students taught redox reactions using CCMIS had significantly higher mean retention scores than those taught using CMIS[F(1, 141)= 204.142, P<0.05]. It was recommended among others that chemistry teacher trainees should be trained on the use of CCMIS and serving teachers should be encouraged to use CCMIS.

description: In der vorliegenden Bachelorarbeit wird das Thema Altersarmut bei Seniorinnen genauer beleuchtet. Es geht einerseits um die Beantwortung der Fragestellung der Erreichbarkeit armutsbetroffener Seniorinnen damit diese Soziale Teilhabe in der Gesellschaft leben können, und andererseits geht es darum, wieso Frauen einem höheren Verarmungsrisiko ausgesetzt sind und welche sozialpolitischen Faktoren dazu beitragen. Zu Beginn wird Hintergrundwissen erworben, um danach die theoretischen Grundlagen zu Alter und Armut zu erarbeiten. Ebenfalls wird bei diesen Themen die Gender Thematik näher betrachtet. Anschliessend werden zentrale Arbeits- und Handlungsprinzipien der Sozialen Arbeit dargelegt, die aufzeigen sollen welche Ansätze der Sozialen Arbeit im Umgang mit Seniorinnen in Altersarmut zur Verfügung stehen. Des Weiteren werden Handlungs- und Unterstützungsmöglichkeiten der Sozialen Arbeit aufgezeigt, wobei die Rolle der Sozialen Arbeit beim Entgegenwirken der Altersarmut dargestellt wird. Dabei werden Beratungsangebote der Organisation Pro Senectute vorgestellt sowie das Konzept Caring Communitie und deren zwei Projekte. Im Anschluss wird ein Fazit gezogen, bei dem die erarbeiteten Einflussfaktoren der Armut bei Seniorinnen erörtert wird. Es wird festgestellt, dass es einige prägnante Faktoren gibt, die die Altersarmut bei Frauen begünstigt. Es wird weiter ersichtlich, dass die erwähnten Handlungs- und Unterstützungsmöglichkeiten der Sozialen Arbeit geeignete Konzepte sind, um Armutsbetroffenen Seniorinnen eine soziale Teilhabe zu ermöglichen.

description: Kollár introduced in [Ko08] the surfaces $$(x_1^{a_1}x_2+x_2^{a_2}x_3+x_3^{a_3}x_4+x_4^{a_4}x_1=0)\subset \mathbb{P}(w_1,w_2,w_3,w_4)$$ where $w_i=W_i/w^*$, $W_i=a_{i+1}a_{i+2}a_{i+3}-a_{i+2}a_{i+3}+a_{i+3}-1$, and $w^*=$gcd$(W_1,\ldots,W_4)$. The aim was to give many interesting examples of $\mathbb{Q}$-homology projective planes. They occur when $w^*=1$. For that case, we prove that Kollár surfaces are Hwang-Keum [HK12] surfaces. For $w^*>1$, we construct a geometrically explicit birational map between Kollár surfaces and cyclic covers $z^{w^*}=l_1^{a_2 a_3 a_4} l_2^{-a_3 a_4} l_3^{a_4} l_4^{-1}$, where $\{l_1,l_2,l_3,l_4\}$ are four general lines in $\mathbb{P}^2$. In addition, by using various properties on classical Dedekind sums, we prove that: (a) For any $w^*>1$, we have $p_g=0$ iff the Kollár surface is rational. This happens when $a_{i+1} \equiv 1$ or $a_{i}a_{i+1} \equiv -1 ($mod $w^*)$ for some $i$. (b) For any $w^*>1$, we have $p_g=1$ iff the Kollár surface is birational to a K3 surface. We classify this situation. (c) For $w^*>>0$, we have that the smooth minimal model $S$ of a generic Kollár surface is of general type with $K_{S}^2/e(S) \to 1$.
