Needs-based family support – Perception, structures and challenges in practical implementation
such as low-threshold access to services. Beside structural framework conditions in context of family
support, the question arises as to what extent the subjective perception of preventive family support
is one more aspect of utilisation and to what extent preventive family support actually matches the
needs of families. This Study asks as well what connotations and attitudes do families have regarding
family support services? How important do families consider these offers and what are their needs?
Based on a mixed-methods design, the Citizens’ Survey on Family Support was conducted by means
of a standardised questionnaire in combination with interviews of family support users and non-users in
order to elaborate deeper meaning structures through the qualitative analysis method of grounded theory.
Summary survey results point out that family support in Germany includes a wide range of offers, which
can promote a broad array of familial interests and competences, but not all families, diverse as they are,
feel consciously addressed – or else they see obstacles to using family services. Our qualitative results
point out that ‘family support’ as a term is neither clearly identified nor properly understood by many
citizens – or else it has different connotations. However, those families who do use the services – within
the framework of transitioning to parenthood – feel supported in their psychosocial adaptations and
regulatory processes. In relation to results and as compared to other EU countries, practical implications
for further developments in family support approaches are discussed
Coral reef drag coefficients – water depth dependence

The definitive version was published in Journal of Physical Oceanography 47 (2017): 1061-1075, doi:10.1175/JPO-D-16-0248.1.A major challenge in modeling the circulation over coral reefs is uncertainty in the drag coefficient because existing estimates span two orders of magnitude. Current and pressure measurements from five coral reefs are used to estimate drag coefficients based on depth-average flow, assuming a balance between the cross-reef pressure gradient and the bottom stress. At two sites wind stress is a significant term in the cross-reef momentum balance and is included in estimating the drag coefficient. For the five coral reef sites and a previous laboratory study, estimated drag coefficients increase as the water depth decreases consistent with open channel flow theory. For example, for a typical coral reef hydrodynamic roughness of 5 cm, observational estimates, and the theory indicate that the drag coefficient decreases from 0.4 in 20 cm of water to 0.005 in 10 m of water. Synthesis of results from the new field observations with estimates from previous field and laboratory studies indicate that coral reef drag coefficients range from 0.2 to 0.005 and hydrodynamic roughnesses generally range from 2 to 8 cm. While coral reef drag coefficients depend on factors such as physical roughness and surface waves, a substantial fraction of the scatter in estimates of coral reef drag coefficients is due to variations in water depth.The Red Sea field program was supported

Delivering Timely Extension Information with the Agronomic Crops Team in Ohio
The Agronomic Crops Team was formed in 1995 to provide an Extension program that linked all disciplines together in an attempt to provide an integrated delivery mechanism designed to address all producer needs in a timely fashion. The team provides a newsletter, Web site, agronomy meetings and workshops, and a satellite broadcast to better serve state clientele. To date, the impact of the Agronomic Crops Team has been substantial, reaching managers of over 2.6 million acres of production ground in the state with an economic impact of over $11 million
Advancing Nucleosynthesis in Self-consistent, Multidimensional Models of Core-Collapse Supernovae
We investigate core-collapse supernova (CCSN) nucleosynthesis in polar
axisymmetric simulations using the multidimensional radiation hydrodynamics
code CHIMERA. Computational costs have traditionally constrained the evolution
of the nuclear composition in CCSN models to, at best, a 14-species
-network. Such a simplified network limits the ability to accurately
evolve detailed composition, neutronization and the nuclear energy generation
rate. Lagrangian tracer particles are commonly used to extend the nuclear
network evolution by incorporating more realistic networks in post-processing
nucleosynthesis calculations. Limitations such as poor spatial resolution of
the tracer particles, estimation of the expansion timescales, and determination
of the "mass-cut" at the end of the simulation impose uncertainties inherent to
this approach. We present a detailed analysis of the impact of these
uncertainties on post-processing nucleosynthesis calculations and implications
for future models.Comment: Proceedings of the 13th Symposium on Nuclei in the Cosmos. 7-11 July
