Neutrino Emission from HBLs and LBLs
The Synchrotron Proton Blazar model is a promising model to explain high
energy emission from gamma-ray loud BL Lac objects like Mkn 421. In contrast to
leptonic models, the hadronic explanation of gamma-ray emission predicts
ultrahigh energy neutrinos.
The predicted neutrino spectra from a typical High-energy cutoff BL Lac
Object (HBL) and a Low-energy cutoff BL Lac Object (LBL) are presented. We find
that cooling due to muon synchrotron radiation causes a cutoff of the neutrino
spectrum at eV, with the exception of from kaon decay
which may extend to higher energies if meson production takes place in the
secondary resonance region of the cross section.
The impact of the neutrino output from both source populations to the diffuse
neutrino background is discussed.Comment: 4 pages, 3 figures, to appear in: Proc. 27th Int. Cosmic Ray Conf.,

What Makes a Carpet Fly? Cultural Studies in the Indian Ocean
This paper aims to open up a cultural studies conversation on the Indian Ocean. Knowledge of the Indian Ocean should be born of the problems encountered in situ, rather than viewed and assessed from afar in erstwhile colonial centres. Networks and institutional links have to be created to sustain an interdisciplinary conversation leading to this decolonisation of knowledge. In investigating the interplay of commerce and culture, this paper abandons the critical separation of the two in favour of a critical engagement with forces of globalisation. As a precolonial global economy, the Indian Ocean offers considerable historical depth to the current ranking of economic powers. But within a general problematic of the theory of value, there is no doubt that cultural forms (narratives, myths religious beliefs, artefacts) are fundamental to the organising forces of trade, and not just âadding valueâ in market transactions
A Touching and Contagious Captain Cook: Thinking History through Things
For how long can history, as it is conceived in âthe Westâ, continue to attach itself to an exhausted humanism, where âmanâ is central and all the natural and inanimate objects surrounding humans (and linked intimately to human activity) are relegated to the function of support act?This essay argues from anthropological theory that there are fundamentally different sorts of relationships that humans can entertain with non-humans, and that these relationships can have a magical force. When a monument is placed at the spot where an explorer first touched the land, does this impart a contiguous magic? On the other hand, where the stuff of history seems animated, and spreading out without clear connection to impart some small part of the aura to a doll representing the historical figure, are we not dealing with a sympathetic, contagious magic? This essay will experiment with these nonrepresentational forms of energy as they are transferred in domains associated with the figure of Lt. James Cook.What, then, is Cook when he is displaced from âwesternâ history and spread around cultures like a virus? How precarious or robust, then, are the historical certainties associated with Cook-monumentalised Kurnell and its place in time as âthe birthplace of modern Australiaâ
Avoiding hospitalisation: effective primary care interventions
Ambulatory care sensitive conditions (ACSCs) ârepresent a range of conditions for
which hospitalisation should be able to be avoided because the disease or condition
has been prevented from occurring, or because individuals have had access to
timely and effective primary careâ. This RESEARCH ROUNDup investigates the
factors that may predict avoidable hospital admissions. It also provides an overview
of interventions that may be effective in reducing avoidable hospitalisations, and
follows from a previous issue that examined the scope of ACSCs in Australia, and
their reliability as a measure of primary health care (PHC) performance
Local community reporting models for regional primary health care organisations
Community reporting models used by primary health care organisations (PHCOs) in New Zealand,
Canada (Ontario), England and Scotland were reviewed. The roles, functions and mandated
community engagement requirements for these PHCOs varied, shaping the scope of their reporting.
All countries included in this report recognised the importance of engaging the community in
healthcare and the value of communication between service providers, service commissioners and
the public. All countries were involved in receiving information from the community to inform
decisions relating to the planning, design and implementation of health care services. It was,
however, difficult to ascertain the extent of this involvement, and how well disadvantaged groups
were included in this process
Avoiding hospitalisation: ambulatory care sensitive conditions
This RESEARCH ROUNDup examines the scope of ambulatory care sensitive
conditions (ACSC) in Australia, and their reliability as a measure of primary health
care (PHC) performance. Avoidable hospitalisation statistics for Australia, Victoria
and New South Wales are presented. Complications of diabetes are the most
common ACSCs encountered in Australia. Rurality and socio-economic disadvantage
are linked to avoidable hospitalisation
