description: Establishment of an LC equation and of a local fields equation describing per­manently localized photons from the analysis of kinetic energy circulation within the en­ergy structure of the double-particle photon that Louis de Broglie hypothesized in the early 1930's. Among other interesting features, these equations provide a mechanical explanation to the localized photon properties of self-propelling at the speed of light and of self-guiding in straight line when no external interaction tends to deflect its trajectory. This paper summarizes the seminal considerations that led to the establishment of the mechanical conversion processes involving electromagnetic energy and mass from electromagnetic photon emission to nucleon construction from the trispatial geometry perspective.

description: Auf einen Blick...

Die Zahl der Menschen, die erst mit 65 Jahren in Altersrente geht, steigt seit über fünf Jahren stetig an und machte zuletzt (2010) immerhin etwa 40 Prozent der Bevölkerung in diesem Alter aus.
Ebenfalls gestiegen sind direkte Übergänge aus stabiler Beschäftigung in Altersrente. Bundesweit war ein Drittel der Neurentner/innen des Jahres 2010 in den drei Jahren unmittelbar vor Rentenbeginn versicherungspflichtig beschäftigt. Dennoch: Selbst unter westdeutschen Männern, unter denen stabile Erwerbsbiographien nach wie vor verbreitet sind, geht nicht einmal jede zweite Person aus stabiler sozialversicherungspflichtiger Beschäftigung in Altersrente.
Besonders stark gestiegen ist der Anteil der Altersübergänge aus stabiler Beschäftigung im Alter von 65 Jahren. Ging 2004 jede/r Sechste der stabil Beschäftigten erst mit 65 in Rente, so war es 2009 jede/r Dritte, der/die bis zum Erreichen der Regelaltersgrenze beschäftigt war. Die übrigen zwei Drittel der stabil Beschäftigten nutzten die nach wie vor bestehenden vorzeitigen Rentenzugangsmöglichkeiten.
Gestiegen ist in den letzten Jahren außerdem die Inanspruchnahme der Altersrente für Schwerbehinderte: Jede/r achte Neurentner/in ging 2010 in diese Rentenart. Die Altersrente für Schwerbehinderte ist seit 2006 als einzige Altersrentenart für Männer verblieben, die – mit Abschlägen – ab einem Alter von 60 Jahren bezogen werden kann, sofern eine Schwerbehinderung anerkannt wurde.
Rentenzugänge aus Langzeiterwerbslosigkeit haben seit 2008 abgenommen. Obwohl gerade bei den Langzeiterwerbslosen ein Aufschieben des Rentenbeginns zu beobachten ist, sind die Abschläge im Durchschnitt besonders hoch, die durchschnittlichen Rentenzahlbeträge vergleichsweise niedrig und – anders als bei den stabil Beschäftigten – in den letzten Jahren deutlich sinkend.

description: One of the most striking features of quantum mechanics is the profound effect exerted by measurements alone. Sophisticated quantum control is now available in several experimental systems, exposing discrepancies between quantum and classical mechanics whenever measurement induces disturbance of the interrogated system. In practice, such discrepancies may frequently be explained as the back-action required by quantum mechanics adding quantum noise to a classical signal. Here we implement the 'three-box' quantum game of Aharonov and Vaidman in which quantum measurements add no detectable noise to a classical signal, by utilising state-of-the-art control and measurement of the nitrogen vacancy centre in diamond. Quantum and classical mechanics then make contradictory predictions for the same experimental procedure, however classical observers cannot invoke measurement-induced disturbance to explain this discrepancy. We quantify the residual disturbance of our measurements and obtain data that rule out any classical model by > 7.8 standard deviations, allowing us for the first time to exclude the property of macroscopic state-definiteness from our system. Our experiment is then equivalent to a Kochen-Spekker test of quantum non-contextuality that successfully addresses the measurement detectability loophole.

description: The lifetime of the J=2+ state in 10C was measured using the Doppler Shift Attenuation Method following the inverse kinematics p(10B,n)10C reaction at 95 MeV. The 2+ state, at 3354 keV, has tau = 219\pm(7)stat \pm(10)sys fs corresponding to a B(E2) # of 8.8(3) e2fm4. This measurement,combined with that recently determined for 10Be (9.2(3) e2fm4), provides a unique challenge to abinitio calculations, testing the structure of these states, including the isospin symmetry of the wave functions. Quantum Monte Carlo calculations using realistic two- and three-nucleon Hamiltonians that reproduce the 10Be B(E2) value generally predict a larger 10C B(E2) probability but with considerable sensitivity to the admixture of different spatial symmetry components in the wave functions, and to the three-nucleon potential used.

Year: 2022

description: Purpose of the Project: Despite years of research to prevent, manage, and treat hypertension, it is still a global public health problem affecting the adult population in the United States and the World in general. African American adults have a high prevalence of hypertension compared to the other racial or ethnic groups, resulting in excess morbidity and mortality. The purpose of this project is to implement a lifestyle modification program to improve hypertension control among the African American population at a local church through physical activities including brisk walking, jogging, and biking and a heart-healthy diet following the Dietary Approach to Stop Hypertension to improve Systolic Blood Pressure and Diastolic Blood Pressure readings over an eight-week period. Methodology: Observational study design using a pre and post statistically design test of a convenience sample of 25 consented African American adults from a local church who were aged 18 and over, who were prescribed antihypertensive medications by their healthcare provider and were able to read, understand and speak the English language, and have a smart mobile device or computer. A parametric paired sample t-test was used to determine the mean difference of systolic blood pressure and diastolic blood pressure for pre-and post-intervention using the IBM SPSS Statistics Version 27. Results: There was a statistically significant reduction in systolic blood pressure readings after implementing lifestyle modification. About 61% of the participants had their systolic blood pressure improved from 140-159 to 130-139, a reduction of about 10-15 mmHg after the implementation. Implications for Practice: Clinically, hypertensive African American adults on medications should also include a non-pharmacological program to improve their hypertension control, lower their risk of cardiovascular disease, and cerebrovascular disease. Finally, to decrease mortality and morbidity rate for better health benefits. Economically, this will reduce the nation’s financial burden.

description: We present a rigorous framework for the composition of Web Services within a higher order logic theorem prover. Our approach is based on the proofs-as-processes paradigm that enables inference rules of Classical Linear Logic (CLL) to be translated into pi-calculus processes. In this setting, composition is achieved by representing available web services as CLL sentences, proving the requested composite service as a conjecture, and then extracting the constructed pi-calculus term from the proof. Our framework, implemented in HOL Light, not only uses an expressive logic that allows us to incorporate multiple Web Services properties in the composition process, but also provides guarantees of soundness and correctness for the composition.

description: This study uses a cultural studies framework to investigate whether the Canadian Skinhead subculture exists as a solution to problems in the social structure experienced by its members. Participant observation, including in-depth interviews, document analysis, and field work carried out in Calgary, Alberta from December, 1993 to March, 1994, was used as a procedure by which to investigate the meanings associated with membership in the Canadian Skinhead subculture in the 1990s. It is argued that although the Canadian Skinhead subculture employs many characteristics of the original British Skinheads, a partial transformation in the form the subculture adopts has occurred in accordance with the changing social circumstances. While the Canadian Skinhead subculture exists as a form of 'resistance' to dominant hegemony, the resistance tends to be 'magical' in the sense that it does not fundamentally alter the social and economic circumstances of its members.

description: Benchmarking is defined as a process of continuous improvement based on the comparison of an organization’s processes with those identified as best practice, thereby allowing for establishing improvement targets and promoting changes for better project outcomes. Despite its importance, incorporating it into an organization’s routine is a cumbersome and time-consuming endeavor as it entails considerable time and human effort. Moreover, it lacks a systematic approach to capturing the similarity of projects for generating credible performance comparisons. With the widespread implementation of Building Information Modeling (BIM) and technological advancements in the construction industry, new opportunities for improvement in benchmarking have emerged. In response, the overarching goal of this dissertation is to advance benchmarking practice by addressing major problems identified from current benchmarking processes in two different aspects. First, this research introduces a benchmarking framework that leverages BIM data for semi-automating a benchmarking data collection. To accomplish the goal, this research examines the feasibility and functional requirements of such an approach by investigating diverse BIM models created for real-world projects. As a consistent approach to obtaining reliable benchmarking data from BIM is essential, this research also develops a formalized representation schema that transforms information stored in BIM into benchmarking data focusing on neutral information models. Second, this research proposes a new approach that finds groups of similar projects by capturing project similarity. In this research, critical and flexible features are selected with the use of data analytics and data mining techniques. Based on the features, the method generates a set of rules that produces different groups of similar projects by performance metric, which enables reliable performance comparisons. The studies presented in this dissertation are carried out by focusing on a healthcare benchmarking program. This dissertation advances current benchmarking practices by streamlining the benchmarking process and allowing for more targeted metric comparisons. This dissertation contributes to integrating BIM with benchmarking practices by introducing a methodology to realize the BIM-based benchmarking and proposing a comprehensive and expandable representation schema to obtain reliable benchmarking data from BIM. It also contributes to establishing a systematic project grouping method that supports decision making for performance improvements.
Radio & Optical Interferometry: Basic Observing Techniques and Data Analysis

Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)

description: Astronomers usually need the highest angular resolution possible, but the blurring effect of diffraction imposes a fundamental limit on the image quality from any single telescope. Interferometry allows light collected at widely-separated telescopes to be combined in order to synthesize an aperture much larger than an individual telescope thereby improving angular resolution by orders of magnitude. Radio and millimeter wave astronomers depend on interferometry to achieve image quality on par with conventional visible and infrared telescopes. Interferometers at visible and infrared wavelengths extend angular resolution below the milli-arcsecond level to open up unique research areas in imaging stellar surfaces and circumstellar environments. In this chapter the basic principles of interferometry are reviewed with an emphasis on the common features for radio and optical observing. While many techniques are common to interferometers of all wavelengths, crucial differences are identified that will help new practitioners avoid unnecessary confusion and common pitfalls. Concepts essential for writing observing proposals and for planning observations are described, depending on the science wavelength, angular resolution, and field of view required. Atmospheric and ionospheric turbulence degrades the longest-baseline observations by significantly reducing the stability of interference fringes. Such instabilities represent a persistent challenge, and the basic techniques of phase-referencing and phase closure have been developed to deal with them. Synthesis imaging with large observing datasets has become a routine and straightforward process at radio observatories, but remains challenging for optical facilities. In this context the commonly-used image reconstruction algorithms CLEAN and MEM are presented. Lastly, a concise overview of current facilities is included as an appendix.

The relation of optical/UV and X-ray emission in low-luminosity active galactic nuclei
Creators: name: Xu, Ya-Di
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We study the relation of optical/UV and X-ray emission in the low luminosity active galactic nuclei (LLAGNs), using a sample of 49 sources including 28 local Seyfert galaxies and 21 low-ionization nuclear emission-line regions (LINERs) with the optical/UV spectral luminosity at the wavelength λ=2500Å, 23.0\leq \log L_{ν(2500Å)(erg/s/Hz)\leq 27.7, and the X-ray spectral luminosity at 2 keV, 20.5\leq \log L_{ν(2 keV)}\leq 25.3. The strong correlations are found between the X-ray luminosity and the optical/UV to X-ray index, α_{ox}, with the optical/UV luminosity, with the slopes very similar to the findings for the luminous AGNs in the previous works. The correlation between α_{ox} and L_{ν(2 keV) is very weak as that found for the luminous AGNs in the majority of previous similar works. We also study the relation between $α_{\rm ox} and the Eddington ratio L_{bol}/L_{Edd} for our sample and find a significant anti-correlation for the sources with L_{bol}/L_{Edd}\lesssim 10^{-3}, which is opposite to the correlation between the two variables for the luminous AGNs. Using the advection dominated accretion flow (ADAF) model, we roughly reproduce this anti-correlationship for the two variables for the LLAGNs. This result strongly supports the ADAF as a candidate accretion mode in LLAGNs.

A Comprehensive ALMA Study of MM-wave Continuum Emission from Hard X-ray Selected Nearby AGNs
Creators: name: Kawamuro, Taiki
Publisher: name: Zenodo
Year: 2023

description: AGNs emit radiation across a wide range of wavelengths. However, until the advent of ALMA, the AGN mm-wave emission has been poorly understood. While the mm-wave emission may be due to thermal and synchrotron components extending from the infrared and cm-wave bands, respectively, ALMA has found an excess explainable by synchrotron self-absorption (SSA) emission from the AGN X-ray corona. Thus, the mm-wave emission may provide a crucial insight into the central engine of AGNs. To study the emission in more detail, we analyzed subarcsec Band-6 ALMA data of 98 nearby AGNs (z<0.05) from the Swift/BAT catalog. This sample provides the largest number of AGNs with high spatial resolution sampling (~1-200 pc), and is almost unbiased for obscured systems. We found a tight relation of 1 mm and X-ray luminosities with a scatter of ~0.36 dex. While the mm-wave emission thus may be the SSA from the X-ray corona, we also discuss other possible origins, including dust emission, outflow-driven shock, and small-scale (<200 pc) jets. We ruled out dust emission as a dominant source, as the mm-wave slope is generally flatter than expected. Also, the lack of an increase in the mm-wave luminosity with the Eddington ratio suggests that a radiation-driven outflow is possibly not a common mechanism. We furthermore found that the mm-wave luminosity is independent of inclination-angle indicators, inconsistent with a simple jet model. Overall, our results put important constraints on the mm-wave origin.

description: Direct searches for dark matter lead to serious problems for simple models with stable neutral Weakly Interacting Massive Particles (WIMPs) as candidates for dark matter. A possibility is discussed that new stable quarks and charged leptons exist and are hidden from detection, being bound in neutral dark atoms of composite dark matter. Stable -2 charged particles $O^{--}$ are bound with primordial helium in O-helium (OHe) atoms, being specific nuclear interacting form of composite dark matter. The positive results of DAMA experiments can be explained as annual modulation of radiative capture of O-helium by nuclei. In the framework of this approach test of DAMA results in detectors with other chemical content becomes a nontrivial task, while the experimental search of stable charged particles at LHC or in cosmic rays acquires a meaning of direct test for composite dark matter scenario.

The scheme is based on the exponential transfer function of a fast transistor, which generates an exponentially rising envelope that is transferred first on a radio frequency carrier, and then on a coherent cw laser beam with an electro-optical phase modulator (EOM). The temporally shaped sideband is then extracted with an optical resonator and can be used to efficiently excite a single Rb-87 atom.

description: Let G be a finite group and let H be a subgroup of G. The Chermak-Delgado measure of H with respect to G is the product of the order of H with the order of the centralizer of H. Originally described by A. Chermak and A. Delgado, the collection of all subgroups of G with maximal Chermak-Delgado measure, denoted CD(G), is a sublattice of the lattice of all subgroups of G. In this paper we note that the members of CD(G) are subnormal in G and determine the Chermak-Delgado lattice of direct products. We additionally describe the lattice for certain kinds of wreath products and examine the behavior of centrally large subgroups, a subset of the Chermak-Delgado lattice.

description: Structural and stratigraphic boundaries between late Paleozoic and early Mesozoic oceanic assemblages, the early Paleozoic North American outer continental margin, and the late Proterozoic to early Paleozoic North American miogeocline are preserved in the southern Kootenay Arc of southeastern British Columbia, in the Pend d'Oreille River area. This dissertation provides the first detailed interpretation of the structural and tectonic evolution of the southern Kootenay Arc. In the Pend d'Oreille River area the oceanic and outer continental margin assemblages are condensed against the North American miogeocline by the Waneta, Tillicum Creek and Argillite faults. All of these faults are margin-ward verging thrust faults, which are overturned at high structural levels. Mapping conducted during this study suggests that some of the Cambrian metasedimentary rocks in the hangingwall of the Argillite fault, previously mapped as Laib Formation, are laterally continuous, and correlative, to the Index Formation of the Lardeau Group. The recognition of Index Formation rocks within the study area provides the basis for the first regional structural interpretation of the southern Kootenay Arc. In addition, an erosional unconformity at the top of the Index Formation was identified during this study, indicating that a pre-Mississippian deformational event affected the North American outer continental margin in the Pend d' Oreille River area. The Argillite fault is herein interpreted to be a segment of a thrust fault that extends the length of the southern Kootenay Arc. The complete structure is described in this dissertation, and is referred to as the Kootenay Thrust. The Kootenay Thrust is a craton-ward verging thrust fault, overturned at high structural levels, that carried an island arc assemblage, marginal basin assemblages, and the lower Paleozoic outer continental margin assemblage in its hangingwall over lower to middle Paleozoic miogeoclinal stratigraphy in its footwall. This dissertation provides the first whole-rock major, trace, rare earth element, and Rb/Sr analyses of two Cretaceous stocks, and the first whole-rock major and trace element analyses of Paleozoic metabasite rocks in the Pend d' Oreille River area.

description: Current approaches for the discovery, specification, and provision of services ignore the relationship between the service contract and the conditions in which the service can guarantee its contract. Moreover, they do not use formal methods for specifying services, contracts, and compositions. Without a formal basis it is not possible to justify through formal verification the correctness conditions for service compositions and the satisfaction of contractual obligations in service provisions. We remedy this situation in this paper. We present a formal definition of services with context-dependent contracts. We define a composition theory of services with context-dependent contracts taking into consideration functional, nonfunctional, legal and contextual information. Finally, we present a formal verification approach that transforms the formal specification of service composition into extended timed automata that can be verified using the model checking tool UPPAAL.

description: A subgroup Q is commensurated in a group G if each G conjugate of Q intersects Q in a group that has finite index in both Q and the conjugate. So commensurated subgroups are similar to normal subgroups. Semistability and simple connectivity at infinity are geometric asymptotic properties of finitely presented groups. In this paper we generalize several of the classic semistability and simple connectivity at infinity results for finitely presented groups. In particular, we show that if a finitely generated group G contains an infinite finitely generated commensurated subgroup Q of infinite index in G, then G is semistable at infinity. If additionally G and Q are finitely presented and either Q is 1-ended or the pair (G,Q) has one filtered end, then G is simply connected at infinity. This result leads to a relatively short proof of V. M. Lew's theorem that finitely presented groups with infinite finitely generated subnormal subgroups of infinite index are semistable at infinity.

description: A toy model for glioma treatment by a radio frequency electric field is suggested. This low-intensity, intermediate-frequency alternating electric field is known as the tumor-treating-field (TTF). In the framework of this model the efficiency of this TTF is estimated, and the interplay between the TTF and the migration-proliferation dichotomy of cancer cells is considered. The model is based on a modification of a comb model for cancer cells, where the migration-proliferation dichotomy becomes naturally apparent. Considering glioma cancer as a fractal dielectric composite of cancer cells and normal tissue cells, a new effective mechanism of glioma treatment is suggested in the form of a giant enhancement of the TTF. This leads to the irreversible electroporation that may be an effective non-invasive method of treating brain cancer.

description: We calculate the branching ratios of pure annihilation type decays $B^0\rightarrow D_{s}^{-}K_{2}^{*+}$ and $B_s\rightarrow \bar{D}a_{2}$ using the perturbative QCD approach based on $k_T$ factorization. The branching ratios are predicted to be $(60.6_{-16.5\,-10.4\,-2.1}^{+17.3\,+4.3\,+3.2}) \times 10^{-6}$ for $B^0\rightarrow D_{s}^{-}K_{2}^{*+}$, $(1.1_{-0.4\,-0.2\,-0.1}^{+0.4\,+0.1\,+0.1})\times 10^{-6}$ for $B_s\rightarrow \bar{D}a_{2}^{0}$ and $(2.3_{-0.8\,-0.4\,-0.1}^{+0.8\,+0.2\,+0.1})\times 10^{-6}$ for $B_{s}\rightarrow D^{-}a_{2}^{+}$. They are large enough to be measured in the ongoing experiment. Due to the shortage of contributions from penguin operators, there are no direct CP asymmetries for these decays in the standard model. We also derive simple relations among these decay channels to reduce theoretical uncertainties for the experiments to test the accuracy of theory and search of new physics signal.

description: Während vielerorts noch diskutiert wird, ob das Wahlalter auf 16 abgesenkt werden soll, ist es in mehreren Ländern bereits Realität. Oft hatte dies positive Auswirkungen auf die Wahlbeteiligung junger Menschen, wie mehrere Forschungsprojekte gezeigt haben. Daraus ergibt sich der Auftrag Fragestellungen zum Wahlalter vom ob zum wie weiterzuentwickeln. In dieser internationalen Recherche untersuchen Dr. Jan Eichhorn und Dr. Christine Hübner daher, was einerseits erfolgreiche Kampagnen zum „Wahlalter 16“ ausgezeichnet hat und zum anderen wie eine Implementierung aussehen sollte, um nachhaltige Wirkung zu erzielen. Dazu sprachen sie mit Forschenden und Aktivist:innen aus mehreren Ländern und erläutern durch Fallbeispiele aus der internationalen Praxis wie politische Jugendbeteiligung gestärkt werden kann.

description: The article addresses the problem of detecting presence and location of a small low emission source inside of an object, when the background noise dominates. This problem arises, for instance, in some homeland security applications. The goal is to reach the signal-to-noise ratio (SNR) levels on the order of $10^{-3}$. A Bayesian approach to this problem is implemented in 2D. The method allows inference not only about the existence of the source, but also about its location. We derive Bayes factors for model selection and estimation of location based on Markov Chain Monte Carlo (MCMC) simulation. A simulation study shows that with sufficiently high total emission level, our method can effectively locate the source.

Studies of the role(s) of galectin in quail intestinal mucin organization and secretion

description: A program of studies was undertaken to explore the role(s) played by galectins at the mucosal surface. The first phase of this project involved purification and characterization of intestinal galectins from rabbit, rat, and quail. A family of galectins were found in mammalian intestinal tissues, however, only a single galectin was identified from the quail. In the second stage of this project, quail intestinal mucin was purified and the biochemical and immunological properties were characterized. Quail mucin was purified by two sequential isopycnic density-gradient centrifugations in CsCl followed by gel filtration chromatography. Purified quail mucin was then characterized by SDS-PAGE, amino acid and carbohydrate composition analyses, immuno-cross reactivity with mammalian mucin antibodies and sensitivity to disulphide-reduction, H2O2 , and trypsin. Quail mucin was revealed to be high molecular weight polymer composed of large heterogeneous glycoprotein monomers and a 110 kD 'link' protein, held together by disulphide bonds. Quail mucin was further identified as a putative ligand for quail galectin in binding studies and through immunohistochemical co-localization in goblet cells. The quail galectin binds quail mucin through the B-galactose residues on the carbohydrate side chains of quail mucin as shown by hapten inhibition studies. A putative membrane receptor of quail galectin on the brush border membrane of the quail small intestine was also detected by radioactive ligand binding assays. The regulation of mucin secretion from the quail small intestine was investigated using in vitro organ culture. Mucin secretion was enhanced by cholera toxin and regulated in a similar fashion to mammalian mucin; being stimulated by cholinergic but not adrenergic stimuli and being sensitive to the activation of protein kinase C and changes in Ca2 + levels. Quail galectin seems to serve as an adhesion molecule for extracellular mucus gel adherence to the epithelial surfaces and maybe also serve as a control for mucin release, which is evidenced by the following discoveries: (1) lactose could release both quail galectin and quail mucin from intestinal tissue; (2) blocking of galectin binding to the mucosal surfaces with antiserum against quail galectin could induce quail mucin release; and (3) binding the mucosal receptors for quail galectin with plant lectins could specifically reduce the rate of baseline secretion of quail mucin. However, lactose-induced mucin release was independent of the muscarinic receptor, protein kinase C and Ca2 +, suggesting that quail galectin may control mucin release through a unique pathway.

description: In two long-duration balloon flights over Antarctica, the BESS-Polar collaboration has searched for antihelium in the cosmic radiation with higher sensitivity than any reported investigation. BESS- Polar I flew in 2004, observing for 8.5 days. BESS-Polar II flew in 2007-2008, observing for 24.5 days. No antihelium candidate was found in BESS-Polar I data among 8.4\times 10^6 |Z| = 2 nuclei from 1.0 to 20 GV or in BESS-Polar II data among 4.0\times 10^7 |Z| = 2 nuclei from 1.0 to 14 GV. Assuming antihelium to have the same spectral shape as helium, a 95% confidence upper limit of 6.9 \times 10^-8 was determined by combining all the BESS data, including the two BESS-Polar flights. With no assumed antihelium spectrum and a weighted average of the lowest antihelium efficiencies from 1.6 to 14 GV, an upper limit of 1.0 \times 10^-7 was determined for the combined BESS-Polar data. These are the most stringent limits obtained to date.

description: Auf einen Blick...

Immer mehr ältere Menschen zwischen 55 und 64 Jahren gehen in Europa einer Beschäftigung nach. Ältere Männer sind generell häufiger als Frauen erwerbstätig, allerdings hat die Alterserwerbstätigkeit unter den Frauen prozentual stärker zugenommen.
Durch den starken Anstieg der Erwerbstätigenquoten von Älteren – insbesondere unter den Frauen – und die nur moderate Zunahme bei den unter 55-Jährigen haben sich die Quoten der Älteren und der Jüngeren angenähert: Die "Alterslücke" verkleinert sich.
Die Beschäftigung im Alter hängt stark vom Qualifikationsniveau ab: Personen mit höheren Qualifikationsabschlüssen sind bedeutend häufiger beschäftigt als Perso-nen mit niedrigen. Bei den Hochqualifizierten ist die "Alterslücke" deutlich geringer als bei Personen mit einem niedrigeren Qualifikationshintergrund. Aber unter älteren Personen mit niedriger Qualifikation hat die Erwerbsbeteiligung besonders zugenommen.
Demographische Effekte unterstützen den Anstieg der Alterserwerbsbeteiligung fast überall in Europa. In Deutschland ist der demographische Effekt vergleichsweise stark, doch zwei Drittel der Zunahme der Alterserwerbstätigenquote gehen in Deutschland auf einen realen Anstieg der Alterserwerbsbeteiligung zurück.
Es sind nicht nur mehr Ältere erwerbstätig, sondern sie bleiben auch länger in Beschäftigung als es noch in der zweiten Hälfte der 1990er Jahre der Fall war. In Deutschland hat sich die Rückzugsrate aus Erwerbstätigkeit um ein Viertel und damit sehr deutlich reduziert.
Mit zunehmendem Alter steigt bei Männern und Frauen der Anteil derjenigen mit reduzierten Arbeitszeiten. Besonders deutlich nimmt deren Anteil ab einem Alter von 65 Jahren zu. In höherem Alter ist eine Weiterbeschäftigung eher mit reduzierter Arbeitszeit möglich.

description: Since the large amplitude 2007 outburst which heated its accreting, pulsating white dwarf, the dwarf nova system GW Librae has been cooling to its quiescent temperature. Our Hubble Space Telescope ultraviolet spectra combined with ground-based optical coverage during the 3rd and 4th year after outburst show that the fluxes and temperatures are still higher than quiescence (T=19,700K and 17,300K vs 16,000K pre-outburst for a log g=8.7 and d=100 pc). The K{wd} of 7.6+/-0.8 km/s determined from the CI1463 absorption line, as well as the gravitational redshift implies a white dwarf mass of 0.79+/-0.08 Msun. The widths of the UV lines imply a white dwarf rotation velocity vsin i of 40 km/s and a spin period of 209 s (for an inclination of 11 deg and a white dwarf radius of 7x10^{8} cm). Light curves produced from the UV spectra in both years show a prominent multiplet near 290 s, with higher amplitude in the UV compared to the optical, and increased amplitude in 2011 vs 2010. As the presence of this set of periods is intermittent in the optical on weekly timescales, it is unclear how this relates to the non-radial pulsations evident during quiescence.
