description: Ο Καισάριος Δαπόντες υπήρξε ένας από τους αξιολογώτερους και πολυγραφότερους συγγραφείς του 18ου αι. Ο "Καθρέφτης Γυναικών" είναι ένα από τα πιο σημαντικά έργα του. Πρόκειται για μια έμμετρη αναδιήγηση ιστοριών, "κακών τε και καλών γυναικών", κυρίως από την Παλαιά Διαθήκη, αλλά και από άλλες πηγές. Στόχος του έργου είναι να τέρψει τους αναγνώστες, αλλά και να τους διδάξει και να τους ωφελήσει ψυχικά, προβάλλοντας ιδίως την γυναίκα του 18ου αιώνα, πρότυπα προς μίμηση και παραδείγματα προς αποφυγή.
description: Cesarios Dapontes was one of the major and prolific writers of 18 century. The "Women's mirror" is one of his most important writings. It's about a metric narration of stories, "bad and good women", especially from the Old Testament and from others fountains. Writing's intention is to please the readers and teach them and benefit their souls, bringing out especially the woman of 18 century, models of emulation and examples of avoidance.

description: The dilatometric properties (α, ϑ, Tg) and viscosity of glasses within the systems Li2O-K2O-B2O3-SiO2 and Na2O-B2O3-SiO2 with constant ratios B2O3/R2O =1.5 and 1 (in mol%) were characterized. These compositions have suitable thermal properties to be used as sealants for molten carbonate fuel cells (MCFC). The changes in dilatometric properties and viscosity due to phase separation and crystallization processes were measured along the different stages of a thermal treatment simulating the startup and working conditions of the MCFC. Thus, the thermal and mechanical behaviour of the studied glasses can be evaluated for the whole thermal cycle of the cell. Transmission electron microscopy (TEM) was used to analyse the development of microstructure during the thermal treatment and X-ray diffraction (XRD) to determine the appearing crystalline phases.

description: We theoretically and experimentally investigate type II second harmonic generation in III-V-on-insulator wire waveguides. We show that the propagation direction plays a crucial role and that longitudinal field components can be leveraged for robust and efficient conversion. We predict that the maximum theoretical conversion is larger than that of type I second harmonic generation for similar waveguide dimensions and reach an experimental conversion efficiency of 12 %/W, limited by the propagation loss.
Arm, erwerbstätig und prekarisiert

description: Armut existiert auch in der reichen Schweiz. Sie betrifft unter anderem so genannte Working-Poor. Das sind Personen, die quasi Vollzeit erwerbstätig sind und doch zu wenig Einkommen erlangen, um ihren Lebensunterhalt zu finanzieren. Hinzu kommen neue Formen der Prekarisierung der Arbeitswelt. Sie unterlaufen erkämpfte Standards der sozialen Sicherheit. Mit betroffen sind viele Kinder in sozial benachteiligten Familien. Sie werden oft einfach weg definiert. Vordringlich wären das Anheben der unteren Löhne sowie das Ausweiten der Ergänzungsleistungen auf alle Haushalte, die darauf angewiesen sind. Die reiche Schweiz kann sich das erlauben. Geld ist genug vorhanden. Was fehlt, ist der politische Wille.

In wealthy Switzerland poverty does exist too. Affected by poverty are amongst others so called working poor, people that work full time but generate an income too small to make ends meet. In addition new forms of a precarisation of work emerge. These forms undermine hard-won and well-established standards of social security. And they affect many children from socially disadvantaged families, a fact nobody seems willing to take notice of. Urgent measures to be taken are an increase of low wages and the expansion of supplementary benefits to all households in need. Switzerland, a country of wealth, is able to afford such measures. Sufficient funds are available. Only obstacle is a lack of political will.

description: We study the signatures of rotational and phase symmetry breaking in small rotating clouds of trapped ultracold Bose atoms by looking at rigorously defined condensate wave function. Rotational symmetry breaking occurs in narrow frequency windows, where the ground state of the system has degenerated with respect to the total angular momentum, and it leads to a complex wave function that exhibits vortices clearly seen as holes in the density, as well as characteristic vorticity. Phase symmetry (or gauge symmetry) breaking, on the other hand, is clearly manifested in the interference of two independent rotating clouds.

Sunspot simulations: penumbra formation and the fluting instability

description: The fluting instability has been suggested as the driver of the subsurface structure of sunspot flux tubes. We conducted a series of numerical experiments where we used flux tubes with different initial curvatures to study the effect of the fluting instability on the subsurface structure of spots. We used the MURaM code, which has previously been used to simulate complete sunspots, to first compute four sunspots in the slab geometry and then two complete circular spots of opposite polarities. We find that the curvature of a flux tube indeed determines the degree of fluting the flux tube will undergo - the more curved a flux tube is, the more fluted it becomes. In addition, sunspots with strong curvature have strong horizontal fields at the surface and therefore readily form penumbral filaments. The fluted sunspots eventually break up from below, with lightbridges appearing at the surface several hours after fluting commences.

description: We investigate one-point reduction methods of finite topological spaces. These methods allow one to study homotopy theory of cell complexes by means of elementary moves of their finite models. We also introduce the notion of h-regular CW-complex, generalizing the concept of regular CW-complex, and prove that the h-regular CW-complexes, which are a sort of combinatorial-up-to-homotopy objects, are modeled (up to homotopy) by their associated finite spaces. This is accomplished by generalizing a classical result of McCord on simplicial complexes.

description: Single-photon sources are key building blocks in most of the emerging secure telecommunication and quantum information processing schemes. Semiconductor quantum dots (QD) have been proven to be the most prospective candidates. However, their practical use in fiber-based quantum communication depends heavily on the possibility of operation in the telecom bands and at temperatures not requiring extensive cryogenic systems. In this paper we present a temperature-dependent study on single QD emission and single-photon emission from metalorganic vapour-phase epitaxy-grown InGaAs/GaAs QDs emitting in the telecom O-band at 1.3 μm. Micro-photoluminescence studies reveal that trapped holes in the vicinity of a QD act as reservoir of carriers that can be exploited to enhance photoluminescence from trion states observed at elevated temperatures up to at least 80 K. The luminescence quenching is mainly related to the promotion of holes to higher states in the valence band and this aspect must be primarily addressed in order to further increase the thermal stability of emission. Photon autocorrelation measurements yield single-photon emission with a purity of g(2)50K(0)=0.13 up to 50 K. Our results imply that these nanostructures are very promising candidates for single-photon sources at elevated (e.g., Stirling cryocooler compatible) temperatures in the telecom O-band and highlight means for improvements in their performance.

Volume changes caused by alkali ions in borate, germanate and silicate glasses and their relation to cation mobility
Creators: name: Kirchheim, Reiner
Publisher: name: Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft
Year: 2022
Subjects: subject: 660

description: It can be shown that volume changes in silicate, borate and germanate glasses can be simply described by the ionic volumes of the corresponding cation addition, if these changes are related to the total number of oxygen atoms. Changes in the volume per mole oxygen are also caused by a varying coordination number as in the case of borate and germanate glasses. Molar volumes defined this way obey simple superposition rules for binary and ternary glasses. In addition, the volume per oxygen atom (or mole), a measure of the average distance of oxygen atoms, provides a quantity which is closely related to the diffusion of gas atoms and alkali ions. Thus a decreasing (increasing) volume per mole oxygen gives rise to a decrease (increase) of the diffusion coefficient of cations or gas atoms. Examples will be presented where this relation is fulfilled qualitatively or quantitatively even. For the quantitative description of diffusion the volume changes caused by external hydrostatic pressure and their known effect on diffusion will be used, in order to model the effect of volume changes caused by a changing composition.

description: In the numerical optimization of a new robotized glass blowing method, convection coefficient and glass viscosity are considered as parameters most influential in the forming process. Consequently, two tests in the industrial framework have been developed. In the first, the temperature is measured by a pyrometer on a glass ingot moved in rotation by the robot. In the second one, the robot holds the glass ingot vertically and the lengthening of the glass is recorded by video camera. In both cases, numerical modelling coupled with the inverse method completes the identification procedure. Finally, the integration of the identified properties in the modelling of the elongation of the glass considerably improves the representation of the real glass flow.

description: Plant stem cells are contained within niches like the root apical meristem (RAM) which create new cells for organ growth, plant stem cells may also be initiated post-embryogenesis like for the development of lateral roots. Secondary growth from the meristems of the vascular and cork cambia also occurs in roots and in some species specialised roots are formed for storage, in response to environmental cues and symbiotic and pathogenic microorganisms. Thus root organogenesis provides a widely variable model to examine one of biology's great questions, how can stem cells be created and maintained and how is differentiation specified and controlled? This thesis describes original proteomic and transcriptomic approaches to gene discovery in a variety of root organogenesis systems using the model legume Medicago truncatula. I used proteomics to compare the meristem and differentiating zones from primary and lateral roots and present and examination the effect of meristem inhibiting herbicide acetohydroxyacid synthase on the meristem proteome. I used transcriptomics to characterise the Medicago RAM by comparing the root meristem and non-meristem and extended this microarray analysis further to examine the very early steps of root formation in an in vitro root organogenesis system. These experiments have identified a host of transcription factors that are commonly expressed in root meristems, these genes will have an important role in future studies of the genetic networks controlling plant stem cells in root and nodule organogenesis.

description: Vibrational spectra are measured for calcium aluminosilicate glasses with the composition (in mol%) xCaO ∙ xAI2O3 ∙ (100 - 2x)SiO2. The OH bands show a systematic change with x in both MIR and NIR regions. The strongly asymmetric band at about 3550 cm-1 shifts to lower wave numbers with increasing x. In the same way the OH combination band at about 4500 cm-1 shifts to lower wave numbers. For the 3550 cm-1 band an extinction coefficient of about 60 1 ∙ mol-1 ∙ cm-1 is suggested for all the samples with x from 15 to 32. For the 4500 cm-1 band the extinction coefficient decreases from 1.0 to 0.49 1 ∙ mol-1 ∙ cm-1 with increasing x from 15 to 32. Systematic changes in the Raman and IR reflectance spectra reflect the substitution of Al3+ for Si4+ and a corresponding increase of Ca2+ in the network. Thus, the vibrational spectra can be related to a fully polymerized network without or with a small amount of nonbridging oxygens also for glasses with x ≥ 25.

description: We report on the study of state-changing collisions between Rydberg atoms and ground state atoms. We employ high-resolution momentum spectroscopy to identify the final states. In contrast to previous studies, we find that the outcome of such collisions is not limited to a single hydrogenic manifold. We observe a redistribution of population over a wide range of final states. We also find that even the decay to states with the same $l$ as the initial state, but different principal quantum number $n$ is possible. We model the underlying physical process in the framework of a short-lived Rydberg quasi-molecular complex, where a charge exchange process gives rise to an oscillating electric field that causes transitions within the Rydberg manifold. The distribution of final states shows a diffusive-like behavior.

description: The widespread rise of a modern conservation ethic has seen national parks, archaeological parks, nature reserves and a host of other forms of protected area (PA) spread to almost every corner of the globe. As a body of thought and practice that was developed initially in western industrialised societies, the spread of modern, state initiated conservation has been a spectacular success as far as increasing the total area of protected land and waters is concerned, but it has not always been a straightforward process as far as the on ground work of managing landscapes for conservation is concerned. In particular, the ideal of state run PAs preserving pristine natural areas has proven difficult to reconcile with on the ground realities in developing countries and on Indigenous lands, where sometimes tens of thousands of people will live in and depend on protected landscapes for economic and cultural reasons. 30 years after participatory planning methods and co-management emerged, where are we up to with cross-cultural collaborations in conservation? An initial point to be made is that interactions between western oriented conservationists and local, culturally distinct communities have been sustained to the extent that at times PAs are not only the subject of intercultural dialogue, but have become the products of intercultural engagement. PAs in some cases have moved beyond a standoff between western and non-western views of nature, culture and conservation, and are now in some important ways bi-cultural entities. What are the implications of this process for on-ground conservation work? Presenting case material from Australia and Timor-Leste, I{u2019}ll focus on how the growth of the conservation estate in Australia has been fuelled in part by the growth in Indigenous owned land, and secondly on how traditional institutions in Timor-Leste have played a key role in facilitating social and political change in the past. Both these cases support the argument that developing {u2018}bi-cultural{u2019} PAs can broker alliances in support of conservation among local communities.

Τα αποτελέσματα έδειξαν ότι υπάρχουν σημαντικές διαφορές όσον αφορά την αντοχή τους στην αλατότητα. Η Zard ήταν η πιο ευαίσθητη, ενώ η Ascolana η πιο ανθεκτική. Οι υπόλοιπες δύο ποικιλίες παρουσίασαν ενδιάμεση συμπεριφορά με την Arbequina να είναι ελαφρώς ανώτερη της κορωνέικης.
description: The effects of Nacl salinity on some physiological parameters of four olive cultivars (Zard, Ascolana, Koroneiki and Arbequina) were studied. Parameters measured were shoot length, photosynthesis, stomatal conductance, chlorophyll fluoresence, chlorophyll concentration, leaf water potential, total carbohydrate content and ploline accumulation in the leaves. The results showed that there were significant differences in the self stres tolerance between the four olive cultivars. The cv. Zard was the less tolerant, while cv. Ascolana was the most tolerant. The other two cultivars showed intermidiate tolerance.

description: Ultrafast optical excitation with intense mid-infrared and terahertz pulses has emerged as a new tool to control materials dynamically. As most experiments are performed with femtosecond pulse excitation, typical lifetimes of most light-induced phenomena in solids are of only few picoseconds. Yet, many scientific applications require longer drive pulses and lifetimes. Here, we describe a mid-infrared pump - terahertz-probe setup based on a CO$\mathrm{_2}$ laser seeded with 10.6 $\mathrmμ$m wavelength pulses from an optical parametric amplifier, itself pumped by a Ti:Al$\mathrm{_2}$O$\mathrm{_3}$ laser. The output of the seeded CO$\mathrm{_2}$ laser produces high power pulses of nanosecond duration, which are synchronized to the femtosecond laser. Hence, these pulses can be tuned in pulse duration by slicing their front and back edges with semiconductor-plasma mirrors irradiated by replicas of the femtosecond seed laser pulses. Variable pulse lengths from 5 ps to 1.3 ns are achieved, and used in mid-infrared pump, terahertz-probe experiments with probe pulses generated and electro-optically sampled by the femtosecond laser.

Randomized benchmarking in the presence of time-correlated dephasing noise
Creators: name: Qi, Jiaan

Year: 2020
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Randomized benchmarking has emerged as a popular and easy-to-implement experimental technique for gauging the quality of gate operations in quantum computing devices. A typical randomized benchmarking procedure identifies the exponential decay in the fidelity as the benchmarking sequence of gates increases in length, and the decay rate is used to estimate the fidelity of the gate. That the fidelity decays exponentially, however, relies on the assumption of time-independent or static noise in the gates, with no correlations or significant drift in the noise over the gate sequence, a well-satisfied condition in many situations. Deviations from the standard exponential decay, however, have been observed, usually attributed to some amount of time correlations in the noise, though the precise mechanisms for deviation have yet to be fully explored. In this work, we examine this question of randomized benchmarking for time-correlated noise---specifically for time-correlated dephasing noise for exact solvability---and elucidate the circumstances in which a deviation from exponential decay can be expected.

description: We consider refractive index sensing with optical bounds states in the continuum (BICs) in dielectric gratings. Applying a perturbative approach we derived the differential sensitivity and the figure of merit of a sensor operating in the spectral vicinity of a BIC. Optimisation design approach for engineering an effective sensor is proposed. An analytic formula for the maximal sensitivity with an optical BIC is derived. The results are supplied with straightforward numerical simulations.

description: We study the stability and the attractor dynamics of an elongated Bose-Einstein condensate with dark or grey kink solitons in the presence of localized dissipation. To this end, the 3D Gross-Pitaevskii equation with an additional imaginary potential is solved numerically. We analyze the suppression of the snaking instability in dependence of the dissipation strength and extract the threshold value for the stabilization of the dark soliton for experimentally realistic parameters. Below the threshold value, we observe the decay into a solitonic vortex. Above the stabilization threshold, we observe the attractor dynamics towards the dark soliton when initially starting from a grey soliton. We find that for all initial conditions the dark soliton is the unique steady-state of the system - even when starting from the BEC ground state.

description: Emission from the interstellar medium can be a significant contaminant of measurements of the intensity and polarization of the cosmic microwave background (CMB). For planning CMB observations, and for optimizing foreground-cleaning algorithms, a description of the statistical properties of such emission can be helpful. Here we examine a machine learning approach to inferring the statistical properties of dust from either observational data or physics-based simulations. In particular, we apply a type of neural network called a Variational Auto Encoder (VAE) to maps of the intensity of emission from interstellar dust as inferred from Planck sky maps and demonstrate its ability to a) simulate new samples with similar summary statistics as the training set, b) provide fits to emission maps withheld from the training set, and c) produce constrained realizations. We find VAEs are easier to train than another popular architecture: that of Generative Adversarial Networks (GANs), and are better-suited for use in Bayesian inference.

Prekarisierung. Geschlechterperspektive. Ethik

Publisher: name: UB Tübingen
Year: 2015

description: In diesem Beitrag wird die Prekarisierungsdebatte aus geschlechterkritischer Sicht aufbereitet und unter Berücksichtigung der systemischen Prekarität weiblicher Arbeits- und Fürsorgepraxis im Kontext des kapitalistischen Wohlfahrtsstaats vertieft und erweitert. Die Relevanz der geschlechterspezifischen Arbeitsteilung und der Reproduktionssphäre wird unterstrichen, unter Aufnahme internationaler Perspektiven in Forschung und in sozialen Bewegungen. Es folgt eine Reflektion über ideologische, religiöse und ethische Implikationen von Prekarisierung und ihrer Kritik, die mit Eckpunkten biblischer Sozialkritik konfrontiert werden. Schlussendlich wird im Licht dieser Analysen das Profil einer kritischen und sozial profilierten Sozialethik anvisiert.

The debate about precarisation in modern capitalist welfare systems deals with the marginalization resp. social exclusion of employees and the unemployed. Feminist scholars have criticized the androcentrism of several of its assumptions and interpretations and hence the exclusion of relevant dimensions of both, labor and social care. They also investigate how precarious life and working conditions question gender role models. The article resumes the main lines of these critiques. It then reflects on ethical, ideological and religious implications of precarisation and explains the Biblical approach to precarious living conditions as a consequence of Exodus, Covenant and social rights. The conclusion outlines a socially situated, gender aware and critical social ethics in the light of these analyses.

description: We demonstrate an all-fiber spatiotemporal mode-locked laser based on graded-index multimode fiber. Due to the high damage threshold of graded-index multimode fiber devices, the output single-pulse energy reach up to 11.67 nJ. The beam quality at mode-locked state is significantly improved compared with continuous wave state as a result of the self-cleaning effect. By amplifying the pulse in the multimode fiber amplifier, high power pulses with high beam quality can be obtained in the all-fiber system based on graded-index MMFs.

description: The crystallization behavior of selected glasses in the multicomponent SiO2-Li2O-ZnO-K2O-P2O5 system was investigated using high-temperature X-ray diffraction and differential scanning calorimetry. Proceeding from a dental model glass with the molar composition 63.2 SiO2, 29.1 Li2O, 3.3 ZnO, 2.9 K2O and 1.5 P2O5, 20 glasses were melted, varying the concentrations of the single components systematically. Glass compositions mainly influenced the formations and dissolutions of metastable and stable phases in the temperature range of 480 to 1100 °C. In the majority of the glasses hthium disilicate (Li2Si2O5) precipitated as the main crystal phase during heating, while lithium metasilicate, lithium orthophosphate, cristobalite and quartz crystallized as secondary phases. After a one-step heat treatment microstructures of glass-ceramics and morphologies of Li2Si2O5 crystals were characterized by scanning electron microscopy. With few exceptions glass-ceramics showed a finegrained microstructure with interlocking, rodshaped Li2Si2O5 crystals with 0.5 to 10 µm in length. The corresponding glass-ceramics were processed by a hot-pressing technique to test samples for mechanical and optical measurements. Concentration variations of the base glasses caused bending strengths between 224 and 675 MPa. Within a comparison of translucency according to dental standard BS 5612 contrast ratios between 0.3 and 0.8 were determined.
Cosmological horizons radiate

description: Gibbons and Hawking [Phys. Rev. D 15, 2738 (1977)] have shown that the horizon of de Sitter space emits radiation in the same way as the event horizon of the black hole. But actual cosmological horizons are not event horizons, except in de Sitter space. Nevertheless, this paper proves Gibbons' and Hawking's radiation formula as an exact result for any flat space expanding with strictly positive Hubble parameter. The paper gives visual and intuitive insight into why this is the case. The paper also indicates how cosmological horizons are related to the dynamical Casimir effect, which makes experimental tests with laboratory analogues possible.
Three-dimensional flow and thermal structures in glass melting furnaces : Part I. Effects of the heat flux distribution

description: This paper presents a study of the flow and thermal structures in the molten glass bath of a typical glass melting furnace with a throat but without air bubblers or electric boosting. Different separate effects on the flow structure of the glass melt are simulated, but only the glass melt is considered. The net heat flux distribution is imposed at the combustion space/glass melt interface, and its effects on the flow and thermal structures of the glass melt are analyzed in a systematic manner by changing the heat flux distribution while keeping the total heat input to the glass bath constant. The main purpose of the work is to evaluate the capability of the furnace operators to control the glass flow and temperature fields by adjusting the firing in the combustion space. The physical phenomena affecting the flow structure in the glass melt are analyzed and discussed in detail. The major results of the study indicate that a) the heat flux distribution has no significant effect on the flow structure of the glass melt under the batch blanket where several Rayleigh Benard cells develop in the spanwise direction, b) a heat flux gradient in the longitudinal direction is required to generate two recirculation loops in this direction, and c) a steep heat flux gradient in the refining part of the tank significantly increases the size of the refining recirculation loop near the front wall.

description: The glass composition (in mol%) 16 Na2O ∙ 24 B2O3 ∙ 60 SiO2 has suitable viscosity and dilatometric properties to be used as sealing material for the gas manifolds of molten carbonate fuel cells (MCFC). Nevertheless, quartz crystallization takes place during sintering of the borosilicate glass powder at temperatures between 600 and 700 °C. The quartz crystallization leads to the formation of pores and a variation in the thermal expansion coefficient; both giving rise to defects and tensions in the seal. In this work, the possibility of inhibition of quartz crystallization by substituting AI2O3 or ZrO2 for 2 or 5 mol% of SiO2 is described. The thermal properties and the viscosity-temperature curve of the new compositions, especially those containing alumina do not differ much from the original glass.

description: We report on photometric follow-up of the recently discovered transiting planet WASP-1b. We observed two transits with the Wise Observatory 1m telescope, and used a variant of the EBOP code together with the Sys-Rem detrending approach to fit the light curve. Assuming a stellar mass of 1.15 M_sun, we derived a planetary radius of R_p = 1.40 +- 0.06 R_J and mass of M_p = 0.87 +- 0.07 M_J. An uncertainty of 15% in the stellar mass results in an additional systematic uncertainty of 5% in the planetary radius and of 10% in planetary mass. Our observations yielded a slightly better ephemeris for the center of the transit: T_c [HJD] = (2454013.3127 +- 0.0004) + N_tr * (2.51996 +- 0.00002). The new planet is an inflated, low-density planet, similar to HAT-P-1b and HD209458b.

Precare. Prekarität im Lebenszusammenhang: Die zwei Gesichter der Care-Prekarität
Creators: name: Amacker, Michèle
Publisher: name: UB Tübingen
Year: 2015

description: Vor dem Hintergrund der aktuellen Care-Krise plädiert der Beitrag für eine erweiterte Analyse von Prekarität: Neben Erwerbsarbeit soll der gesamte Lebenszusammenhang in den Blick genommen werden. Der Beitrag geht anhand zweier Fallanalysen der Frage nach, wie Haushalte mit erhöhtem Care-Bedarf zunehmend unter Druck geraten. Die beiden Fälle machen auf komplementäre Weise care-spezifische Prekarität im Schatten der Erwerbsarbeitsgesellschaft sichtbar: Nicht nur, wer pflegebedürftig wird, auch wer lange Zeit selbst Angehörige pflegt, läuft Gefahr, in eine prekäre Lebenslage zu rutschen. Dabei sind zunehmend sämtliche Lebensbereiche von Unsicherheit betroffen. Und soziale Ausgrenzung nimmt ihren Lauf.

In the context of the current care crisis this article argues for an extended analysis of precariousness: beyond paid employment the whole life situation must be taken into account. The article analyses two cases to examine how households with increased care requirements are coming under increased pressure. The two complementary cases illuminate care-specific forms of precariousness obscured in a society geared towards paid. Not only those who are in need of care themselves but also those who care for family members for extended periods of time are in danger of sliding into a precarious life situation. In these cases, insecurity gradually extends to all areas of life and social exclusion sets in.
