Beeinflussen berufstypische Arbeitszeitmerkmale die Unterbrechungsdauer von Frauen? Eine längsschnittliche Analyse der Bedeutung beruflicher Merkmale für die Berufsrückkehr von Müttern in Deutschland
Authors: Hondralis Irina , Buchholz Sandra 
Published: September 2017

This article analyses how occupation-specific hours of employment influence the employment interruptions of women after family formation, and whether employment hours have an impact on different educational groups. This study uses detailed longitudinal data from the German National Educational Panel Study and aggregated occupational data from the Microcensus. Our results show how occupation-specific employment hours, even after controlling for individual characteristics, significantly influence the employment interruptions of mothers. The interruption duration of women with tertiary education is solely influenced by the amount of overtime working hours associated with specific occupations. This result indicates that the return-to-work of tertiary educated women remain mostly unaffected by their hours of employment, and likely to be attributed to both elevated opportunity costs and higher career orientations. Whilst medium and less educated women reduce their time-out from their occupation when the working hours are short and working from home is possible. Atypical employment hours, such as night-shift or weekend work, are found to be exclusively relevant for less educated women. Overall, our results demonstrate that hours of employment play an important role for the employment continuity of women without a tertiary education.
Zusammenfassung
Der Beitrag geht der Frage nach, ob berufstypische Arbeitszeitmerkmale die Erwerbsunterbrechungsdauer von Frauen nach der Familiengründung beeinflussen und welche Bedeutung berufstypische Arbeitszeitmerkmale für Frauen mit unterschiedlichem Bildungsniveau haben. Dazu wurden die Längsschnittdaten der Erwachsenenkohorte des Nationalen Bildungspanels über ein Daten-Linkage mit aggregierten Berufsdaten aus dem Mikrozensus angereichert. Die Ergebnisse der empirischen Analysen zeigen, dass sich berufstypische Arbeitszeiten neben Individualmerkmalen signifikant auf die Berufsrückkehr von Müttern auswirken. Für hochqualifizierte Frauen erwiesen sich lediglich die für einen Beruf typischen Überstunden als einflussreich. Dieses Ergebnis deutet darauf hin, dass die Rückkehr von Akademikerinnen aufgrund von höheren Opportunitätskosten und womöglich auch einer höhere Erwerbsneigung durch die arbeitszeitlichen Gegebenheiten im Austrittberuf kaum tangiert ist. Für mittel- und insbesondere geringqualifizierte Frauen sind jedoch andere Faktoren, nämlich die Arbeitszeitlänge, die Verbreitung von Heimarbeit und – für beruflich nicht qualifizierte Frauen – auch die Verbreitung von Nacht- und Wochenendarbeit relevant. Insgesamt legen unsere Ergebnisse nahe, dass berufstypische Arbeitszeiten insbesondere für die Unterbrechungsdauer von geringgebildeten Müttern eine bedeutende Rolle spielen.
Essalltag und Arbeitsteilung von Eltern in Paarbeziehungen – Eine quantitative Analyse auf Basis der repräsentativen Zeitverwendungsdaten 2012/13 und 2001/02

Published: September 2017

The article examines the division of labor for everyday food routines of two-parent households depending on their labor force participation. Using data from the representative German Time Use Survey 2001/02 and 2012/13, three different pairs were formed: dual-earner couples, couples with additional female income and male-breadwinner couples Findings show that mother’s employment influences the time used for everyday food routines: It was found that the higher the employment rate of mothers, the less time was spent on food routine activities. Furthermore, the daily time used for everyday food routines was reduced from 2001/02 to 2012/13. The largest reductions were seen in the group of mothers working fulltime. Besides that, fathers were more engaged in meal preparation on the weekends, although the responsibility was the mother’s. In addition, the age and number of children in a household influenced the time used for everyday food routines. However, none of the examined pair constellations can help determine an egalitarian division of everyday food routines. There is still a labor division by gender.
Zusammenfassung
Der Beitrag untersucht die zeitliche Gestaltung sowie die innerfamiliale Arbeitsteilung des Essalltags von Müttern und Vätern in Paarbeziehungen differenziert nach deren Erwerbsumfang. Die Sekundäranalyse erfolgt auf Basis der repräsentativen Zeitverwendungsdaten 2012/13 und 2001/02, wobei drei Paarkonstellationen untersucht werden: Doppelverdiener-Paare, weibliche Zuverdiener- Paare sowie Paare mit männlichem Familienernährer. Die Analyse des Essalltags zeigt, dass der Erwerbsstatus der Mutter die zeitliche Gestaltung des Essalltags beeinflusst. Je höher dieser ist, desto weniger Zeit wird für die Ernährungsversorgung aufgewendet. Darüber hinaus hat sich die tägliche Zeitverwendung für die Ernährungsversorgung von 2001/02 bis 2012/13 reduziert, wobei die stärksten Einsparungen bei vollzeiterwerbstätigen Müttern zu konstatieren sind. Väter engagieren sich verstärkt am Wochenende bei der Mahlzeitenzubereitung, gleichwohl liegt die Verantwortung insgesamt bei den Müttern. Ebenso beeinflussen Alter und Anzahl der Kinder die Zeitverwendung für die Ernährungsversorgung. Letztlich kann in keiner untersuchten Paarkonstellation eine egalitäre Arbeitsteilung zur Gestaltung des Essalltags festgestellt werden. Vielmehr dominieren relativ ausgeprägte geschlechtsspezifische Arrangements.

ABSTRACT

Background and Objectives:
This paper evaluates the performance of a variational level set method for performing label fusion through the use of a penalty term, label fusion term, and length regularization term, which automatically labels objects of interest in biomedical images. This paper is an extension of our preliminary work in the conference paper. We mainly focus on the validation of the variational level set method.

Subjects and Methods:
Label fusion is achieved by combining the three terms: label fusion term, image data term, and regularization term. The curve evolution derived from the energy minimization is impacted by the three terms simultaneously to achieve optimal label fusion. Each label obtained from the nonlinear registration method is represented by a level set function whose zero level contour encloses the labeled region. In Lu et al.'s paper, they employ the level set formulation only for hippocampus segmentation.

Results:
Our method is compared with majority voting (MV), local weighted voting (LWV), and Simultaneous Truth and Performance Level Estimation (STAPLE). The method is evaluated on MICCAI 2012 Multi-Atlas Labeling challenge and MICCAI 2012 ventricle segmentation challenge. The mean Dice metric is computed using different atlases and produces results with 0.85 for the hippocampus, 0.77 for the amygdala, 0.87 for the caudate, 0.78 for the pallidum, 0.89 for the putamen, 0.91 for the thalamus, and 0.78 for cardiac left ventricles.

Conclusions:
Experimental results demonstrate that our method is robust to parameter setting and outperforms MV, LWV, and STAPLE. The image data term plays a key role in improving the segmentation accuracy. Our method can obtain satisfactory results with fewer atlases.
Order 3 Elements in G2 and Idempotents in Symmetric Composition Algebras
Authors: Elduque Alberto 
Published: September 2017

AbstractOrder three elements in the exceptional groups of type G2 are classiûed up to conjugation over arbitrary fields. Their centralizers are computed, and the associated classification of idempotents in symmetric composition algebras is obtained. Idempotents have played a key role in the study and classification of these algebras.Over an algebraically closed field, there are two conjugacy classes of order three elements in G2 in characteristic not 3 and four of them in characteristic 3. The centralizers in characteristic 3 fail to be smooth for one of these classes.

Redaktionelt forord

I mange år er humaniora blevet beskrevet som studiet af det menneskelige. Men som bl.a. videnskabsteoretikeren Donna Haraway har gjort opmærksom på, er ordet "humaniora" ikke alene forbundet med det latinske ord for "menneskelig" (humanus), men også for "muldjord" (humus). Med Passage 77 forsøger vi at styrke denne forbindelse mellem humaniora og det materielle grundlag, som menneskets eksistens bygger på. Under overskriften "Materialitet" bringer nummeret 9 artikler, der på forskellig vis anlægger materielle perspektiver i studiet af litteratur: Hvad kan H.C Andersens tingseventyr fortælle os om menneskets forhold til sin omverden? Hvordan kan man læse vejret i J.P. Jacobsens novelle "Mogens"? Hvilken rolle spiller bakterier i modernistisk litteratur? Og hvordan skaber apostrofen forøget sensibilitet for de materielle ting omkring os? Ved at stille sådanne og lignende spørgsmål bidrager Passage 77 til de seneste års teoretiske diskussioner om det ikke-menneskelige, posthumanisme, klima og biopolitik, hvor nye og alternative idéer om materialitet har indtaget en helt central rolle.
Litteratur og materialitet. En teoretisk overflyvning
Authors: Gregersen Martin , Skiveren Tobias 
Published: September 2017

Martin Gregersen & Tobias Skiveren: “Literature and Materiality: A Theoretical Overview”In recent years, the slogan of materialism has resonated across the Humanities. Concepts like “language”, “culture”, and “discourse” are increasingly going out of fashion as practices of denaturalization no longer provoke the shock and awe they did in the early heydays of poststructuralism. Meanwhile, the language of “matter”, “life”, and “the nonhuman” is spreading rapidly, accompanied by the promise of alternative ways of thinking and new modes of inquiry. This article outlines some of the main tenets of this turn toward materiality. Bringing together theories of Bruno Latour, Jane Bennett, and Graham Harman, the main aim is to sketch out similarities and differences within this new philosophical trend and identify some of its potential for transforming literary criticism.
Can squirrel monkeys learn an ABnA grammar? A re-evaluation of Ravignani et al. (2013)
Authors: Ghirlanda Stefano 
Published: September 2017

Ravignani et al. (2013) habituated squirrel monkeys to sound sequences conforming to an ABnA grammar (n = 1, 2, 3), then tested them for their reactions to novel grammatical and non-grammatical sequences. Although they conclude that the monkeys “consistently recognized and generalized the sequence ABnA,” I remark that this conclusion is not robust. The statistical significance of results depends on specific choices of data analysis, namely dichotomization of the response variable and omission of specific data points. Additionally, there is little evidence of generalization to novel patterns (n = 4, 5), which is important to conclude that the monkeys recognized the ABnA grammar beyond the habituation patterns. Lastly, many test sequences were perceptually similar to habituation sequences, raising the possibility that the monkeys may have generalized based on perceptual similarity rather than based on grammaticality.
The Parenting to Reduce Adolescent Depression and Anxiety Scale: Assessing parental concordance with parenting guidelines for the prevention of adolescent depression and anxiety disorders

Published: September 2017

BackgroundDespite substantial evidence demonstrating numerous parental risk and protective factors for the development of adolescent depression and anxiety disorders, there is currently no single measure that assesses these parenting factors. To address this gap, we developed theParenting to Reduce Adolescent Depression and Anxiety Scale (PRADAS)as a criterion-referenced measure of parental concordance with a set of evidence-based parenting guidelines for the prevention of adolescent depression and anxiety disorders. In this paper, we used a sample of Australian parents of adolescents to: (1) validate the PRADAS as a criterion-referenced measure; (2) examine parental concordance with the guidelines in the sample; and (3) examine correlates of parental concordance with the guidelines.MethodsSeven hundred eleven parents completed the PRADAS, as well as two established parenting measures, and parent-report measures of adolescent depression and anxiety symptoms. Six hundred sixty adolescent participants (aged 12–15) also completed the symptom measures. Concordance with the guidelines was assessed via nine subscale scores and a total score. Reliability of the scores was assessed with an estimate of the agreement coefficient, as well as 1-month test-retest reliability. Convergent validity was examined via correlations between the scale and two established parenting measures.ResultsOne proposed subscale was removed from the final version of the scale, resulting in a total of eight subscales. Reliability was high for the total score, and acceptable to high for seven of the eight subscales. One-month test-retest reliability was acceptable to high for the total score. Convergent validity was supported by moderate to high correlations with two established measures of parenting. Overall, rates of parental concordance with the guidelines were low in our sample. Higher scores were associated with being female and higher levels of parental education. Greater parental concordance with the guidelines was associated with fewer symptoms of depression and anxiety in adolescent participants.DiscussionThis initial validation study provides preliminary support for the reliability and validity of the PRADAS. The scale has potential for use in both clinical and research settings. It may be used to identify parents’ strengths and potential targets for intervention, and as an outcome measure in studies of preventive parenting interventions.
Inconsistent Subsurface and Deeper Ocean Warming Signals During Recent Global Warming and Hiatus

Published: September 2017

AbstractOcean heat content (OHC) evolutions calculated from the data sets (WOA, MyOcean, ORAS4, and SODA) were examined at different depth ranges in this study. According to the OHC changes, the subsurface and deeper ocean (SDO, 300–2000 m) heat content rapidly increased over the world's ocean basins during 1998–2013, indicating significant warming in the SDO during the recent global surface warming hiatus. Almost all the ocean basins warmed up, but with various contributions to the global SDO warming tied to the recent hiatus. The role of the Indian Ocean is particularly important as it has accounted for about 30% of global SDO heat uptake during the hiatus. The combined use of multiple data sets can reveal inconsistencies in SDO warming analysis results, and improve our understanding of the role of the SDO in the recent hiatus. The heat uptake in global SDO during the hiatus was about 2.37, 5.44, 3.75, and 2.44 × 1022 joules with trends of 0.40, 0.70, 0.77, and 0.48 W m−2 according to WOA, MyOcean, ORAS4, and SODA respectively, presenting obviously inconsistent SDO warming signals. MyOcean shows OHC overestimates in different ocean basins, while ORAS4 presents more reliable SDO OHC analysis. In general, the global SDO has sequestered a significant amount of heat—about 3.50 × 1022 joules with trends of 0.59 W m−2 on average among the four data sets—during the recent hiatus, demonstrating widespread and significant warming signals in the global SDO. There remain substantial uncertainties and discrepancies, however (especially in the PO and SO), in the available SDO warming information due to insufficient subsurface observation coverage and variations in the data set generation techniques used among different researchers.
Impact of the Mesoscale Dynamics on Ocean Deep Convection: The 2012–2013 Case Study in the Northwestern Mediterranean Sea

Published: September 2017

AbstractWinter 2012–2013 was a particularly intense and well‐observed Dense Water Formation (DWF) event in the Northwestern Mediterranean Sea. In this study, we investigate the impact of the mesoscale dynamics on DWF. We perform two perturbed initial state simulation ensembles from summer 2012 to 2013, respectively, mesoscale‐permitting and mesoscale‐resolving, with the AGRIF refinement tool in the Mediterranean configuration NEMOMED12. The mean impact of the mesoscale on DWF occurs mainly through the high‐resolution physics and not the high‐resolution bathymetry. This impact is shown to be modest: the mesoscale does not modify the chronology of the deep convective winter nor the volume of dense waters formed. It however impacts the location of the mixed patch by reducing its extent to the west of the North Balearic Front and by increasing it along the Northern Current, in better agreement with observations. The maximum mixed patch volume is significantly reduced from 5.7 ± 0.2 to 4.2 ± 0.6 × 1013 m3. Finally, the spring restratification volume is more realistic and enhanced from 1.4 ± 0.2 to 1.8 ± 0.2 × 1013 m3 by the mesoscale. We also address the mesoscale impact on the ocean intrinsic variability by performing perturbed initial state ensemble simulations. The mesoscale enhances the intrinsic variability of the deep convection geography, with most of the mixed patch area impacted by intrinsic variability. The DWF volume has a low intrinsic variability but it is increased by 2–3 times with the mesoscale. We relate it to a dramatic increase of the Gulf of Lions eddy kinetic energy from 5.0 ± 0.6 to 17.3 ± 1.5 cm2/s2, in remarkable agreement with observations.
