A qualitative study of gender role identity and relationship satisfaction in adults raised in equal parenting households
No full textThis multi-method dissertation study focused on the experiences of adults who were raised in households where cohabitating male and female parents shared parenting tasks equally or near-equally, dividing childcare based on criteria other than gender. An online survey of 182 females and 52 males over 18 years of age was utilized to examine the relative frequency of shared parenting in the survey sample, to identify subjects who experienced the highest degree of shared parenting for more in depth, qualitative study, and to identify relevant demographic factors such as age and race of those adults who experienced shared parenting as children. Survey data also provided information on the degree of sharing of various childcare tasks at different ages of children, and on the frequency of male and female parents working outside the home at various ages of their children. Ten interview participants were then chosen for qualitative study based on having experienced a high level of shared parenting and their current relationship status. They participated in semi-structured interviews focused on their respective experiences of their parents’ sharing of childcare and on the impact of this parenting style on each subject’s later gender role identity and relationship satisfaction. Interviews were transcribed verbatim based on the methodology described by McCracken (1988), and common themes were identified. To provide corroborative quantitative data related to gender role identity and relationships satisfaction, interview subjects were also given the Bem Sex Role Inventory and Dyadic Adjustment Scale-7. Scores were measured against the normed samples for these instruments. Adult children of equally parenting partners interviewed for qualitative study were found to have flexible gender role identities and high relationship satisfaction. Survey findings demonstrated that those under forty years of age were twice as likely to have experienced shared parenting, but that shared parenting has not increased in proportion to the increases in mothers in the workforce.Psy.DIncludes bibliographical referencesby Stephanie L.

Differential gene expression between adult queens and workers in the ant Lasius niger
No full textAnts and other social insects forming large societies are generally characterized by marked reproductive division of labour. Queens largely monopolize reproduction whereas workers have little reproductive potential. In addition, some social insect species show tremendous lifespan differences between the queen and worker caste. Remarkably, queens and workers are usually genotypically identical, meaning that any phenotypic differences between the two castes arise from caste-specific gene expression. Using a combination of differential display, microarrays and reverse Northern blots, we found 16 genes that were differentially expressed between adult queens and workers in the ant Lasius niger, a species with highly pronounced reproductive division of labour and a several-fold lifespan difference between queens and workers. RNA ligase mediated rapid amplification of cDNA ends (RLM-RACE) and gene walking were used to further characterize these genes. On the basis of the molecular function of their nearest homologues, three genes appear to be involved in reproductive division of labour. Another three genes, which were exclusively overexpressed in queens, are possibly involved in the maintenance and repair of the soma, a candidate mechanism for lifespan determination. In-depth functional analyses of these genes are now needed to reveal their exact role
L-band nulling interferometry at the VLTI with Asgard/Hi-5: status and plans
No full textHi-5 is the L’-band (3.5-4.0 μm) high-contrast imager of Asgard, an instrument suite in preparation for the visitor focus of the VLTI. The system is optimized for high-contrast and high-sensitivity imaging within the diffraction limit of a single UT/AT telescope. It is designed as a double-Bracewell nulling instrument producing spectrally-dispersed (R=20, 400, or 2000) complementary nulling outputs and simultaneous photometric outputs for self-calibration purposes. In this paper, we present an update of the project with a particular focus on the overall architecture, opto-mechanical design of the warm and cold optics, injection system, and development of the photonic beam combiner. The key science projects are to survey (i) nearby young planetary systems near the snow line, where most giant planets are expected to be formed, and (2) nearby main sequence stars near the habitable zone where exozodiacal dust that may hinder the detection of Earth-like planets. We present an update of the expected instrumental performance based on full end-to-end simulations using the new GRAVITY+ specifications of the VLTI and the latest planet formation models.Spaceborne Instrumentatio
Internal waves and turbulence in the Antarctic Circumpolar Current

The definitive version was published in Journal of Physical Oceanography 43 (2013): 259–282, doi:10.1175/JPO-D-11-0194.1.This study reports on observations of turbulent dissipation and internal wave-scale flow properties in a standing meander of the Antarctic Circumpolar Current (ACC) north of the Kerguelen Plateau. The authors characterize the intensity and spatial distribution of the observed turbulent dissipation and the derived turbulent mixing, and consider underpinning mechanisms in the context of the internal wave field and the processes governing the waves’ generation and evolution.
The turbulent dissipation rate and the derived diapycnal diffusivity are highly variable with systematic depth dependence. The dissipation rate is generally enhanced in the upper 1000–1500 m of the water column, and both the dissipation rate and diapycnal diffusivity are enhanced in some places near the seafloor, commonly in regions of rough topography and in the vicinity of strong bottom flows associated with the ACC jets. Turbulent dissipation is high in regions where internal wave energy is high, consistent with the idea that interior dissipation is related to a breaking internal wave field. Elevated turbulence occurs in association with downward-propagating near-inertial waves within 1–2 km of the surface, as well as with upward-propagating, relatively high-frequency waves within 1–2 km of the seafloor. While an interpretation of these near-bottom waves as lee waves generated by ACC jets flowing over small-scale topographic roughness is supported by the qualitative match between the spatial patterns in predicted lee wave radiation and observed near-bottom dissipation, the observed dissipation is found to be only a small percentage of the energy flux predicted by theory. The mismatch suggests an alternative fate to local dissipation for a significant fraction of the radiated energy.SW acknowledges the support of the Grantham Institute for Climate Change, Imperial College London.

Design of the VLTI/Hi-5 light injection system
No full textHi-5 is an ERC-funded project hosted at KU Leuven and a proposed visitor instrument for the VLTI. Its primary goal is to image the snow line region around young planetary systems using nulling interferometry in the L’ band, between 3.5 and 4.1 μm, where the contrast between exoplanets and their host stars is very advantageous. The breakthrough is the use of a photonic chip based beam combiner, which only recently allowed the required theoretical raw contrast of 10−3 in this spectral range. The VLTI long baseline interferometry enables to reach high angular resolution (4.2 mas at 3.8 μm wavelength with the Auxiliary Telescopes (ATs)), while high contrast detection is achieved using nulling interferometry. This polarisation requires a high degree of optical symmetry between the four pupils of the VLTI, only possible with precise phase, dispersion and intensity control systems. The instrument is currently in its design phase. In this paper, the warm optics design and the injection system up to the photonic chip are presented. The different properties of the design are presented including the optics used, the characteristics of the four beams and the current drawbacks. Particular attention is devoted to the optical alignment and the tolerance analysis in order to estimate the precision required for the alignment procedure and therefore to choose adapted optical mountings.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Spaceborne Instrumentatio

Producing young adult literature in the 21st century
No full texttextThe book publishing industry experienced a period of drastic change
during the final decades of the twentieth century. Small publishing companies
consolidated and were purchased by large, profit-minded media conglomerates.
The widespread adoption of digital media technologies prompted many questions
about the very future of the book itself. Yet at the pinnacle of these changes, the
American young adult publishing market gradually began to experience not a
decline, but a renaissance. In this report, I explore ways that changes in book
publishing have manifested themselves in contemporary young adult literature
through two case studies. Are today’s young adult books works of literature or
commercial products? Is their increased popularity due to widening readership
or more savvy marketing? Are the companies producing them more concerned
with the public good or their own profit margins?Informatio
