description: Die Frauen- und Geschlechterforschung hat bereits in den 1970er Jahren herausgearbeitet, dass sich das Verhältnis von Arbeit und Geschlecht entlang der Achse Sichtbarkeit/Unsichtbarkeit konstituiert. Die Un/Sichtbarkeit von Arbeit ist grundlegend für die Hervorbringung von Geschlechterungleichheiten, sowohl in Erwerbsarbeit als auch in (unbezahlter) Reproduktionsarbeit. Gleichzeitig wird die Grenze zwischen beiden immer wieder neu verhandelt. Der Beitrag rekonstruiert dieses Verhältnis und untersucht am Beispiel von Digitalisierung, körpernahen Dienstleistungen und der Corona-Pandemie, wie sich durch aktuelle Veränderungen das Verhältnis von Arbeit, Geschlecht und Unsichtbarkeit neu konstituiert und differenziert. Der Beitrag zeigt, dass Unsichtbarkeit als analytische Kategorie in der Erforschung von Arbeit und Geschlechterverhältnissen den Blick auf historische Kontinuitäten genauso wie auf Grenzverschiebungen und Neuaushandlungen schärfen kann.
description: Since the 1970s, women’s and gender studies have demonstrated ways in which relations of work and gender are constituted by in/visibility. The in/visibility of work is essential for gendered inequality, concerning wage labour as much as (unpaid) reproductive work. At the same time, the border between in/visibility is subject to ongoing negotiations. This paper traces back the relationship of in/visibility and draws on examples from the field of digital work, body service work and the corona pandemic in order to research contemporary changes that differentiate and re-constitute work, gender and inequality. We illustrate that invisibility serves as an analytic category researching work and gender relations, which allows for focusing more deeply on historic continuities as much as on shifting borders and negotiations of these relationships.

description: Reinigung ist während der aktuellen Covid-19-Pandemie wichtiger denn je, um besonders in klinischen Räumen die hygienische Sauberkeit aufrechtzuerhalten. Zugleich wird diese Arbeit nach wie vor unter prekären Bedingungen, überwiegend von Frauen* und dabei von Migrant*innen verrichtet. Reinigungskräfte bleiben meist sowohl gesellschaftlich als auch im sozialen Gefüge der Organisation Krankenhaus unsichtbar, sie werden unterschätzt und ausgegrenzt. Diese Unsichtbarkeit ist jedoch vorwiegend eine soziale, denn im Sinne der Kontrolle ihrer Arbeit sind sie auf anstrengende Weise sichtbar. Von der aktuellen Pandemiesituation und einem ethnografischen Forschungsprojekt ausgehend, fragt der Beitrag nach dem Zusammenspiel von Geschlecht, rassistischem Othering und prekärer Arbeit bei der Reinigung im Krankenhaus. Dabei kommt in den Blick, dass Reinigungsarbeit (nicht nur) unter den aktuellen Bedingungen auf eine doppelte Weise verletzbar macht, darin jedoch auch ein veränderndes Potential liegt.
description: Cleaning in the current Covid-19 pandemic is as relevant as ever, far and foremost to maintain hygienic standards in hospitals. At the same time, this line of work is still mostly done by women* and migrants under precarious conditions. Cleaning staff is invisible, undervalued and excluded, societally as well as within the hospital as a social space. However, this invisibility remains on a social level, since their work is visible in a sense that it is controlled in an exhausting way. Based on the current conditions within the pandemic and on the findings of an ethnographic study, the paper explores the relation of gender, racist othering and precarious work in hospital cleaning. It shows that this work under the current conditions is precarious in two ways, but that in these precarities also lies a potential for change.

description: Der Beitrag untersucht die vielschichtigen Ungleichheitsdimensionen im Feld der institutionellen Kleinkinderziehung. Angenommen wird, dass Aspekte des Inferioren mit dieser enervierenden, körperlichen Tätigkeit bis heute verbunden blieben. Diese eher impliziten und damit verdeckt bleibenden gesellschaftlichen Zuschreibungen haben vermutlich mit dem faktischen Anspruchscharakter von Erziehungsarbeit zu tun. Auf Grundlage eines theoretischen Struktur- und Handlungsmodells und von Fallanalysen zum Erzieherinnenberuf wird versucht, die geschlechtsspezifischen Ungleichheitsverhältnisse, denen zudem eine Bildungsungleichheitsproblematik eingeschrieben ist, material zu durchdringen. Hinter der Delegation dieser Arbeit an die Frauen (die Personalstatistik wird ausführlich diskutiert) verbergen sich weitere subtile Formen von Ungleichheit, die mit wissenschaftlicher Distanz, der normativen Verkennung der eigentlichen Kita-Wirklichkeit, der Konfrontation der Praxis mit Konzepten von "Bildung" - letztlich mit der Dignität von Erziehungsarbeit zu tun haben.
description: The contribution examines the complex dimensions of inequality in the field of early childhood education and care. It is assumed that aspects of inferiority have remained associated with this energizing, physical activity until now. These rather concealed social attributions probably have to do with the strained, demanding character of educational work. The gender-specific inequalities are discussed in material terms on the basis of a theoretical structural and action model and of case analyses on the occupation of kindergarten teachers. There is also a problem of educational inequality enrolled. The personnel statistics are discussed in detail. Behind the delegation of this work to women lie other subtle forms of in-equality. They have to do with scientific distance, the normative misjudgment of the reality of day care centres, the confrontation of practice with concepts of "Bildung" - ultimately with the dignity of educational work.

description: Minijobs haben sich seit den 1990er Jahren speziell für Frauen als stabiles Arbeitsmarktsegment etabliert und werden ebenso lange als prekäre Beschäftigungsform problematisiert. Die zentralen Prekaritätsachsen bilden die im Vergleich zu sozialversicherungspflichtig Beschäftigten unterdurchschnittlichen Arbeits- und Beschäftigungsbedingungen sowie die unzureichende Möglichkeit einer eigenständigen sozialen Absicherung. Ausgehend von einer nur marginalen Subjektorientierung in der bisherigen Forschung beleuchtet der Beitrag diese Problemfelder von Minijobs und fragt nach der subjektiven Arbeitsqualität sowie den Ausprägungen und Erklärungsfaktoren der Erwerbspräferenzen von weiblichen Minijobbenden. Die Befunde signalisieren eine divergierende Beurteilung der Arbeitsqualität in unterschiedlichen Dimensionen von Erwerbsarbeit und sensibilisieren somit für den Nutzen mehrdimensionaler und subjektiver Zugänge für die Analyse von Arbeitsqualität. Darüber hinaus offenbart sich eine nur geringe Normalarbeitsorientierung unter (weiblichen) Minijobbenden, deren Ursachen vielfältig sind und nicht ausschließlich auf institutionelle Fehlanreize reduziert werden können.
description: Especially for women, mini jobs have developed into an established form of employment since the 1990s and have been criticised for their precarious potential ever since. The two main aspects subject to critique are the poor working conditions as well as the insufficient level of social security. As previous research has hardly taken a subject-orientated approach towards mini jobs, this article investigates the subjective job quality in mini jobs as well as the individual work preferences of (female) employees. The results indicate diverging evaluations of job quality in different job-related dimensions and hence underline the importance of multi-dimensional and subjective approaches towards job quality. Moreover, the work preferences of (female) mini jobbers are in conflict with full-time employment integration, while the reasons are manifold and not only to be found in institutional factors.

Aufbauend auf Angelika Wetterers Typologie von Geschlechterwissen zeigen sich in diesen Deutungsmustern Unterschiede, woran die Geschlechter(un)gleichheit festgemacht wird, welche Relevanz gleichstellungspolitischen Maßnahmen beigemessen wird und welche Rolle sie für die eigene Praxis gewerkschaftlicher Interessenpolitik spielen. Das frauenpolitische, das geschlechtertheoretische und das konservative Deutungsmuster werden vorgestellt und zugleich diskutiert, unter welchen Bedingungen es trotz dieser Unterschiede gelingen kann, Gleichstellungspolitik als organisationsübergreifende Aufgabe zu etablieren. Die empirische Basis bilden qualitative Interviews, die mit Gewerkschaftssekretär*innen der ver.di, der IG BAU sowie der IG Metall durchgeführt wurden.
description: This contribution is located at the interface of gender studies and sociology of work and organization by comparing the trade union representation of women and at the same time reconstructing typical interpretations in the understanding of trade union gender politics. Based on Angelika Wetterer's typology of gender knowledge (Geschlechterwissen), there are differences in these interpretative patterns, how gender (in)equality is determined, what relevance gender equality measures are attached to and what role they play for the own practice of trade union politics. The women's political, gender-theoretical and conservative interpretative patterns (frauenpolitisches, geschlechtertheoretisches und konservatives Deutungsmuster) are presented and at the same time it will be discussed, under which conditions and despite these differences equality policy can be introduced as a cross-organizational task. The empirical basis is formed by qualitative interviews with trade union secretaries from ver.di, IG BAU and IG Metall.

Basierend auf der ausführlichen Beschreibung der Rahmenkonzeption der Kompetenzmessungen im NEPS (Artelt, Weinert&Carstensen, 2013; Weinert et al., 2019) gewährtder Beitrag zunächst einen kurzen Einblick in die Anlage der längsschnittlich konzipierten Kompetenzmessungen. Im Anschluss werden jeweils für die einzelnen Kompetenzbereiche, die sich domänen-spezifischen Kompetenzen, Metakompetenzen sowie ergänzenden Konstrukten zuordnen lassen, Informationen zu den bisherigen Messungen gegeben und zentrale deskriptive Befunde dargestellt. Hierbei werden sowohl psychometrische Kennwerteals auch Mittelwertsunterschiede für zentrale Gruppierungsvariablen,wie z.B. sozio-ökonomischer Status oder Schultyp, berichtet.

This paper gives an overview of the design and descriptive longitudinal findings of the competence measurements within the National Educational Panel Study (NEPS)for the period from 2010 until 2020. Based on the detailed description of the framework of the competence measurements in the NEPS (Artelt, Weinert&Carstensen, 2013; Weinert et al., 2019), the paper first providesa brief insight into the design of the longitudinal competence measurements. Subsequently, for each of the individual competence areas which can be assigned to domain-specific competences, meta-competences,and supplementary constructs, information on the previous measurements is given and central descriptive findings are presented. Both psychometric parameters and mean differences are reported for central grouping variables such as socio-economic status or school type.

description: Although extreme weather events and slow onset processes have been increasingly linked to human mobility in distinct international governance spaces, research and policy on migration, displacement and planned relocation resulting from slow onset events remain focused mainly on sea level rise or specific hazards such as prolonged droughts. Land and forest degradation and desertification (LFDD), as a driver of population movements and its implications for long-term development policy, have received less attention. Considering the far-reaching impacts of these processes on human systems, this discussion paper aims to examine to what extent the LFDD – human mobility nexus has been integrated in existing policy and legal frameworks in African, Latin American and Caribbean (LAC) countries, identifying pathways towards improved management of population movements related to slow onset events. In this context, this discussion paper also presents national responses to the current COVID-19 pandemic, which has increased vulnerability in areas affected by progressive environmental changes. The analysis builds upon a review of policy and legal documents, and it sets the groundwork for an advanced research and policy agenda on human mobility in the context of LFDD. Even though efforts have been made to acknowledge the topic in African and LAC nations, the findings suggest the need for wider consideration of the LFDD – human mobility nexus in existing domestic frameworks.

description: Motivated by the recent work in skyrmions and active chiral matter systems, we examine pairs and small clusters of repulsively interacting point particles in the limit where the dynamics is dominated by the Magnus force. We find that particles with the same Magnus force can form stable pairs, triples and higher ordered clusters or exhibit chaotic motion. For mixtures of particles with opposite Magnus force, particle pairs can combine to form translating dipoles. Under an applied drive, particles with the same Magnus force translate; however, particles with different or opposite Magnus force exhibit a drive-dependent decoupling transition. When the particles interact with a repulsive obstacle, they can form localized orbits with depinning or unwinding transitions under an applied drive. We examine the interaction of these particles with clusters or lines of obstacles, and find that the particles can become trapped in orbits that encircle multiple obstacles. Under an ac drive, we observe a series of ratchet effects, including ratchet reversals, for particles interacting with a line of obstacles due to the formation of commensurate orbits. Finally, in assemblies of particles with mixed Magnus forces of the same sign, we find that the particles with the largest Magnus force become localized in the center of the cluster, while for mixtures with opposite Magnus forces, the motion is dominated by transient local pairs or clusters, where the translating pairs can be regarded as a form of active matter.

Shapiro Steps and Nonlinear Skyrmion Hall Angles For dc and ac Driven Skyrmions on a Two Dimensional Periodic Substrate

description: For an overdamped particle moving over a two-dimensional periodic substrate under combined dc and ac drives, a series of steps can appear in the velocity force curves that are known as Shapiro steps. Here we show that for skyrmions driven over a two-dimensional periodic obstacle array with a dc drive and an ac drive that is either parallel or perpendicular to the dc drive, the system exhibits numerous transverse and longitudinal synchronization dynamics due to the Magnus force. These phenomena originate in interactions between two different types of phase locking effects: Shapiro steps and directional locking. In some cases, the skyrmion Hall angle is constant but longitudinal Shapiro steps appear, while in other regimes the skyrmion Hall angle can either increase or decrease with increasing dc drive during the phase locking as the skyrmion locks to different symmetry directions of the obstacle lattice. For a transverse ac drive we find that strong Hall angle overshoots can occur in certain locked phases where the skyrmion is moving at an angle that is considerably larger than the intrinsic Hall angle. For the strongest Magnus force, the phase locking effects are reduced and there are larger regions of disordered dynamics. We show that the skyrmion Hall angle can be controlled by fixing the dc drive and changing the amplitude of the ac drive.

description: Communities hosting large numbers of refugees are under immense pressure regarding social cohesion and local economic development, often coupled with inequitable gender roles. As this study demonstrates, cash-for-work (CfW) programmes can mitigate this pressure because – beyond direct effects on employment, infrastructure and skills – they also unfold positive community effects, even in contexts of flight and migration. This study, based on 380 interviews gathered during a 3-months field stay and a GIZ survey of over 980 former participants of the Improving Green Infrastructure in Jordan Programme, details how CfW programmes in Jordan implemented by international donors have supported local communities hosting the majority of circa 600,000 Syrian refugees living outside camps. It argues that such programmes, if skilfully designed, reap sizeable benefits not only for their direct participants, even if – under the current set-up – post-CfW employment and investment effects remain limited and changed gender roles may not be sustained. The study presents recommendations for international and local policymakers on how to factor in community effects when designing policy responses to protracted displacement.

description: It is becoming difficult to meet the fast-rising demand for construction materials having a low environmental impact. The introduction of innovative construction materials is critical in reducing carbon emissions and ensuring that everyone has access to affordable homes. Untested usage of locally produced building materials has resulted in significant carbon emissions and a short building lifespan. Brick, concrete blocks, mud buildings, and stone masonry are the most often used construction materials in Ethiopia. Conventional building materials such as concrete blocks have high carbon emissions. The production and transportation of such material lead to relatively high levels of greenhouse gas emissions. It is observed that the possibility of replacing these materials is not explored enough in the case of Ethiopia. This paper aims to explore the new combination of materials that can replace ‘conventional bricks’ to enhance the environment-friendly nature of the structure. Brick blocks made up of ’Timbercrete’ were explored and experimented with several combinations of mixtures. the ’saw dust’ which is considered waste is used as a primary material in all the compositions. Findings revealed that various material compositions with sawdust can be used as a building material to reduce the cost and environmental impacts. It is also revealed that composition with poor response to the various tests can still be used for certain components in the building.

description: We examine directional locking effects in an assembly of disks driven through a square array of obstacles as the angle of drive rotates from zero to ninety degrees. For increasing disk densities, the system exhibits a series of different dynamic patterns along certain locking directions, including one-dimensional or multiple row chain phases and density modulated phases. For non-locking driving directions, the disks form disordered patterns or clusters. When the obstacles are small or far apart, a large number of locking phases appear; however, as the number of disks increases, the number of possible locking phases drops due to the increasing frequency of collisions between the disks and obstacles. For dense arrays or large obstacles, we find an increased clogging effect in which immobile and moving disks coexist.

description: Providing forecasts for ultra-long time series plays a vital role in various activities, such as investment decisions, industrial production arrangements, and farm management. This paper develops a novel distributed forecasting framework to tackle challenges associated with forecasting ultra-long time series by using the industry-standard MapReduce framework. The proposed model combination approach facilitates distributed time series forecasting by combining the local estimators of time series models delivered from worker nodes and minimizing a global loss function. In this way, instead of unrealistically assuming the data generating process (DGP) of an ultra-long time series stays invariant, we make assumptions only on the DGP of subseries spanning shorter time periods. We investigate the performance of the proposed approach with AutoRegressive Integrated Moving Average (ARIMA) models using the real data application as well as numerical simulations. Compared to directly fitting the whole data with ARIMA models, our approach results in improved forecasting accuracy and computational efficiency both in point forecasts and prediction intervals, especially for longer forecast horizons. Moreover, we explore some potential factors that may affect the forecasting performance of our approach.

description: Directional locking occurs when a particle moving over a periodic substrate becomes constrained to travel along certain substrate symmetry directions. Such locking effects arise for colloids and superconducting vortices moving over ordered substrates when the direction of the external drive is varied. Here we study the directional locking of run-and-tumble active matter particles interacting with a periodic array of obstacles. In the absence of an external biasing force, we find that the active particle motion locks to various symmetry directions of the substrate when the run time between tumbles is large. The number of possible locking directions depends on the array density and on the relative sizes of the particles and the obstacles. For a square array of large obstacles, the active particle only locks to the $x$, $y$, and $45^{\circ}$ directions, while for smaller obstacles, the number of locking angles increases. Each locking angle satisfies $θ= \arctan(p/q)$, where $p$ and $q$ are integers, and the angle of motion can be measured using the ratio of the velocities or the velocity distributions in the $x$ and $y$ directions. When a biasing driving force is applied, the directional locking behavior is affected by the ratio of the self-propulsion force to the biasing force. For large biasing, the behavior resembles that found for directional locking in passive systems. For large obstacles under biased driving, a trapping behavior occurs that is non-monotonic as a function of increasing run length or increasing self-propulsion force, and the trapping diminishes when the run length is sufficiently large.

description: Die Schulschließungen Anfang des Jahres haben das Lehrpersonal, die Schülerinnen und Schüler und die Eltern weitgehend unvorbereitet getroffen. In kurzer Zeit mussten alternative Formen des Unterrichts gefunden werden. Der erste Bericht der Corona-Zusatzbefragungen im Rahmen des Nationalen Bildungspanels (NEPS) beschäftigt sich mit Fragen, wie gut die Familien mit der Situation zurechtkamen: Wie lief das Lernen zuhause ab, wie sah die technische Ausstattung aus und welche Rolle spielten die Eltern? Und welche Arten von (virtuellen) Lernangeboten wurden nun genutzt?

description: Der Arbeitsalltag hat sich im Frühjahr 2020 für viele Erwerbstätige dramatisch verändert. Durch die Beschränkungen in der Corona-Krise mussten viele Arbeitnehmerinnen und Arbeitnehmer ihr Büro kurzfristig in das eigene Zuhause verlegen und dort oftmals auch parallel die Kinderbetreuung übernehmen. Viele Arbeitgeber reagierten mit der Flexibilisierung von Dienstzeiten, Freistellung und Kurzarbeit. Und eine Vielzahl von Berufen wurde als systemrelevant eingestuft. Doch nicht nur äußere Faktoren bestimmten, wie sich die Arbeitssituation der Menschen während der Corona-Krise verändert. Die Auswertung der Corona-Befragung unter Teilnehmenden des Nationalen Bildungspanels (NEPS) zeigt deutlich, welche große Rolle der Bildungsgrad der Erwerbstätigen spielte.

description: We present an analytical formalism, supported by numerical simulations, for studying forces that act on curved walls following temperature quenches of the surrounding ideal Brownian fluid. We show that, for curved surfaces, the post-quench forces initially evolve rapidly to an extremal value, whereafter they approach their steady state value algebraically in time. In contrast to the previously-studied case of flat boundaries (lines or planes), the algebraic decay for the curved geometries depends on the dimension of the system. Specifically, the steady-state values of the force are approached in time as $t^{-d/2}$ in d-dimensional spherical (curved) geometries. For systems consisting of concentric circles or spheres, the exponent does not change for the force on the outer circle or sphere. However, the force exerted on the inner circle or sphere experiences an overshoot and, as a result, does not evolve towards the steady state in a simple algebraic manner. The extremal value of the force also depends on the dimension of the system, and originates from the curved boundaries and the fact that particles inside a sphere or circle are locally more confined, and diffuse less freely than particles outside the circle or sphere.

description: We use analytic arguments and numerical solutions of the continuum, active nematohydrodynamic equations to study how friction alters the behaviour of active nematics. Concentrating on the case where there is nematic ordering in the passive limit, we show that, as the friction is increased, memory effects become more prominent and $+1/2$ topological defects leave increasingly persistent trails in the director field as they pass. The trails are preferential sites for defect formation and they tend to impose polar order on any new $+1/2$ defects. In the absence of noise and for high friction, it becomes very difficult to create defects, but trails formed by any defects present at the beginning of the simulations persist and organise into parallel arch-like patterns in the director field. We show aligned arches of equal width are approximate steady state solutions of the equations of motion which co-exist with the nematic state. We compare our results to other models in the literature, in particular dry systems with no hydrodynamics, where trails, arches and polar defect ordering have also been observed.
