Integration of driver support functions: the driver's point of view
Integration of driver support functions is a key issue in the development of in-vehicle systems that assist the driver with the driving task. This paper discusses a user needs survey that provides more insight into this issue from the perspective of the driver. Car drivers are asked to indicate their needs for driver assistance during certain driving tasks (e.g. congestion driving) and circumstances (e.g. reduced visibility). From this, consequences for the integration of functions can be deduced with respect to technology, HMI and functional operation. Preliminary results of a pilot test of the user needs survey are highlighted in this paper. These results indicate starting points for integrated driver assistance, such as the adaptability of systems based on personal needs for support, and the functional integration of driver support functions, for instance with respect to inter-vehicle communication

Can galaxy growth be sustained through HI-rich minor mergers?
Local galaxies with specific star-formation rates (star-formation rate per
unit mass; sSFR~0.2-10/Gyr) as high as distant galaxies (z~1-3), are very rich
in HI. Those with low stellar masses, log M_star (M_sun)=8-9, for example, have
M_HI/M_star~5-30. Using continuity arguments of Peng et al. (2014), whereby the
specific merger rate is hypothesized to be proportional to the specific
star-formation rate, and HI gas mass measurements for local galaxies with high
sSFR, we estimate that moderate mass galaxies, log M_star (M_sun)=9-10.5, can
acquire sufficient gas through minor mergers (stellar mass ratios ~4-100) to
sustain their star formation rates at z~2. The relative fraction of the gas
accreted through minor mergers declines with increasing stellar mass and for
the most massive galaxies considered, log M_star (M_sun)=10.5-11, this
accretion rate is insufficient to sustain their star formation. We checked our
minor merger hypothesis at z=0 using the same methodology but now with
relations for local normal galaxies and find that minor mergers cannot account
for their specific growth rates, in agreement with observations of HI-rich
satellites around nearby spirals. We discuss a number of attractive features,
like a natural down-sizing effect, in using minor mergers with extended HI
disks to support star formation at high redshift. The answer to the question
posed by the title, "Can galaxy growth be sustained through \HI-rich minor
mergers?", is maybe, but only for relatively low mass galaxies and at high
redshift.Comment: 6 pages, 3 figures; in final acceptance by A&
Two sides of the coin:Patient and provider perceptions of health care delivery to patients from culturally and linguistically diverse backgrounds
BACKGROUND: Australia is a culturally diverse nation with one in seven Australians born in a non-English speaking country. Culturally and Linguistically Diverse (CALD) populations are at a high risk of developing preventable chronic diseases such as cardiovascular disease, type 2 diabetes mellitus, renal disease, and chronic respiratory disease, especially communities from the Pacific Islands, the Middle East, North Africa, the Indian subcontinent and China. Previous studies have shown that access to services may be a contributing factor. This study explores the experiences, attitudes and opinions of immigrants from different cultural and linguistic backgrounds and their health care providers with regard to chronic disease care. METHODS: Five focus groups were conducted comprising participants from an Arabic speaking background, or born in Sudan, China, Vietnam or Tonga. A total of 50 members participated. All focus groups were conducted in the participantsâ language and facilitated by a trained multicultural health worker. In addition, 14 health care providers were interviewed by telephone. Interviews were digitally recorded and transcribed. All qualitative data were analysed with the assistance of QSR NVivo 8 software. RESULTS: Participants were generally positive about the quality and accessibility of health services, but the costs of health care and waiting times to receive treatment presented significant barriers. They expressed a need for greater access to interpreters and culturally appropriate communication and education. They mentioned experiencing racism and discriminatory practices. Health professionals recommended recruiting health workers from CALD communities to assist them to adequately elicit and address the needs of patients from CALD backgrounds. CONCLUSIONS: CALD patients, carers and community members as well as health professionals all highlighted the need for establishing culturally tailored programs for chronic disease prevention and management in CALD populations. Better health care can be achieved by ensuring that further investment in culturally specific programs and workforce development is in line with the number of CALD communities and their needs
Launching Delta Alliance, final report of phase 2
Delta Alliance is a network that aims to improve the resilience of the worldâs deltas. It provides a foundation and framework for international knowledge sharing and development around delta issues. Phase 2 focussed on three components: developing the Delta Alliance organization, initiating network activities and (development of) research and knowledge sharing projects
Completing HI observations of galaxies II. The Coma Supercluster
High sensitivity 21-cm HI line observations, with an rms noise level of \sim
0.5 mJy, were made of 35 spiral galaxies in the Coma Supercluster, using the
refurbished Arecibo telescope, which resulted in the detection of 25 objects.
These data, combined with the measurements available from the literature,
provide the set of HI data for 94% of all late-type galaxies in the Coma
Supercluster with an apparent photographic magnitude m_p <15.7 mag. We confirm
that the typical scale of HI deficiency around the Coma cluster is 2 Mpc, i.e.
one virial radius. Comparing the HI mass function (HIMF) of cluster with
non-cluster members of the Coma Supercluster we detect a shortage of high HI
mass galaxies among cluster members that can be ascribed to the pattern of HI
deficiency found in rich clusters.Comment: 16 pages, 8 figures, 4 tables. Accepted for publication on A&
