What Are the Challenges of Increasing the Sustainability of Urban Livelihoods?
. This article places the challenge of rapid urbanisation throughout the world into a perspective that acknowledges inequalities due to economic history. As well as a brief exploration of the site-specific nature of challenges faced, this article seeks to outline the economic and structural obstacles that act as a backdrop to the lives of the poor. Such a perspective can inform attempts to improve the lot of the poor and help in outlining the moral obligation for the powerful to help the poor and vulnerable face up to the issue of Climate Change
Not All “Designers Are Wankers”: Connecting Design, Enterprise and Regional Cultural Development
This paper reports on how a University’s Designer in Residence Scheme has contributed to both the local cultural and economic regeneration of the design sector in the North East of England. This case study specifically reflects on how the schemes ‘practitioner mentoring’ has created a significant community of practice through the collaborations of a Design School, Enterprise Campus and regional development agencies.
British design education is often bemoaned by the creative industries for failing to properly equip graduates for the ins and outs of the business of design; whilst at the same time it has become a truism of British industry that it innovates but does not make and sell. Northumbria University’s Designer in Residence scheme was established with a view to addressing both of these issues.
A modern university is not wholly or even mainly just an academy. It could rather be seen as a context for the non-academic acquisition of higher-level practical skills, especially in creative fields. This is quite a different activity from the conventional teaching and tutoring process in which most universities, even today, are educationally landlocked. The industrial workshops, studios and ateliers that used to provide the context for this practical skills development no longer exist. It could be argued that they anyway never offered the grounding in independent, effective, self-management that a present day design sector
needs. In the Designer in Residence Scheme such independence is routinely imparted and acquired by succeeding ‘breaking waves’ of designers.
As academic partners on the scheme, the authors reflect on the value and methodologies of the initiative evolved throughout its ten-year span, focusing on the nature of the community of practice established between successive residents, academics and Enterprise Campus and crucially
how the designers have owned the process of developing directional design practice. This creative dialogue has resulted in a number of key findings to be discussed in this paper on the relevance and value of design enterprise to regional development, cultural identity, and economic growth. The paper concludes by discussing the value to Higher Education in developing an integrated approach to
the culture of design, enterprise and manufacture
Two-particle irreducible effective actions versus resummation: analytic properties and self-consistency
Approximations based on two-particle irreducible (2PI) effective actions
(also known as -derivable, Cornwall-Jackiw-Tomboulis or Luttinger-Ward
functionals depending on context) have been widely used in condensed matter and
non-equilibrium quantum/statistical field theory because this formalism gives a
robust, self-consistent, non-perturbative and systematically improvable
approach which avoids problems with secular time evolution. The strengths of
2PI approximations are often described in terms of a selective resummation of
Feynman diagrams to infinite order. However, the Feynman diagram series is
asymptotic and summation is at best a dangerous procedure. Here we show that,
at least in the context of a toy model where exact results are available, the
true strength of 2PI approximations derives from their self-consistency rather
than any resummation. This self-consistency allows truncated 2PI approximations
to capture the branch points of physical amplitudes where adjustments of
coupling constants can trigger an instability of the vacuum. This, in effect,
turns Dyson's argument for the failure of perturbation theory on its head. As a
result we find that 2PI approximations perform better than Pad\'e approximation
and are competitive with Borel-Pad\'e resummation. Finally, we introduce a
hybrid 2PI-Pad\'e method.Comment: Version accepted for publication in Nuclear Physics B. 31 pages, 16

APFIC/FAO Regional Consultative Workshop: Securing sustainable small-scale fisheries: Bringing together responsible fisheries and social development, Windsor Suites Hotel, Bangkok, Thailand 68 October 2010
In the Global Overview, we attempt to view reefs in terms of the poor who are dependent on reefs for their livelihoods, how the reefs benefit the poor, how changes in the reef have impacted the lives of the poor and how the poor have responded and coped with these changes. It also considers wider responses to reef issues and how these interventions have impacted on the lives of the poor
Key Factors Supporting Small-Scale Coastal Fisheries Management
This synthesis was designed to provide an evidence base on the success factors in small-scale coastal fisheries management in developing countries and, in turn, to assist the Rockefeller Foundation in developing its strategy for its Oceans and Fisheries Initiative. In doing so, it identifies and describes some 20 key factors believed to influence success in small-scale coastal fisheries management. The report was completed via a rapid review of key sources of knowledge from formal published literature, institutional literature, key informants and Internet searches. The focus was on key success factors in achieving a balance of social, economic and ecological benefits from the management of small-scale coastal fisheries. A summary of these success factors can also be explored via an interactive visualization that accompanies this report
Ultracold homonuclear and heteronuclear collisions in metastable helium
Scattering and ionizing cross sections and rates are calculated for ultracold
collisions between metastable helium atoms using a fully quantum-mechanical
close-coupled formalism. Homonuclear collisions of the bosonic HeHe and fermionic HeHe systems, and
heteronuclear collisions of the mixed HeHe system,
are investigated over a temperature range 1 K to 1 K. Carefully
constructed Born-Oppenheimer molecular potentials are used to describe the
electrostatic interaction between the colliding atoms, and complex optical
potentials used to represent loss through ionization from the
states. Magnetic spin-dipole mediated transitions from the
state are included and results reported for spin-polarized and unpolarized
systems. Comparisons are made with experimental results, previous
semi-classical models, and a perturbed single channel model.Comment: 14 pages, 9 figure
Towards a Horizontal Theory of Autonomy
This thesis criticises 'hierarchical' accounts of personal autonomy, and outlines the core features of an alternative, 'horizontal' account. It specifically focuses on the conditions of autonomous action. The current dominant approaches to the phenomenon of personal autonomy, or self-governance, tend to isolate certain privileged aspects of the self, that wield control when an agent is autonomous. In this sense, they can be labelled as 'hierarchical' accounts. For instance, Frankfurt's early (1971) account bases the conditions for autonomous action in conformity with an individual's higher-order volitions. However, I argue that such 'hierarchical' approaches are unsatisfactory. Bringing in considerations from Buss (1994, 2013), I argue that they are unable to adequately account for the phenomenon of nonautonomous action, or to explain how these privileged aspects of the soul exert authority over the rest. Instead, I argue for a 'horizontal' account of the self-relation involved when an individual acts autonomously. Such an account does not locate the conditions for autonomous action in some limited subsection of the self, but instead takes a more holistic approach to the aspects of the self that can be involved in self-governance. I suggest that the positive conditions for personal autonomy can instead be understood to involve the individual's conceptualisation of the decision-situation before them, and the range of factors incorporated into their decision-making. Under this kind of account, personal autonomy is a notion admitting of degrees
When is general wariness favored in avoiding multiple predator types?
Free access to article and electronic appendices via DOI.Adaptive responses to predation are generally studied assuming only one predator type exists, but most prey species are depredated by multiple types. When multiple types occur, the optimal antipredator response level may be determined solely by the probability of attack by the relevant predator: "specific responsiveness." Conversely, an increase in the probability of attack by one predator type might increase responsiveness to an alternative predator type: "general wariness." We formulate a mathematical model in which a prey animal perceives a cue providing information on the probability of two predator types being present. It can perform one of two evasive behaviors that vary in their suitability as a response to the "wrong" predator type. We show that general wariness is optimal when incorrect behavioral decisions have differential fitness costs. Counterintuitively, difficulty in discriminating between predator types does not favor general wariness. We predict that where responses to predator types are mutually exclusive (e.g., referential alarm-calling), specific responsiveness will occur; we suggest that prey generalize their defensive responses based on cue similarity due to an assumption of response utility; and we predict, with relevance to conservation, that habituation to human disturbance should generalize only to predators that elicit the same antipredator response as humans
Is It Better to Be Known?: Understanding the Vulnerability of Autistic Individuals in Registry-based Programs Used by Police Services in Ontario, Canada
Registry-based programs have been adopted by many police services in Ontario, Canada, as a voluntary opportunity for vulnerable persons or their caregivers to provide personal information to police in case of crisis or emergency. The overall goal of this dissertation was to provide a foundational understanding of these programs using a grounded theory methodology. This dissertation is comprised of three separate studies that reflect the different forms of grounded theory coding. Study one explored the programs promoted on official police service websites in Ontario, Canada, using inductive qualitative content analysis. This content analysis revealed that sampled police services promote four programs on their websites to address encounters between police and autistic individuals. By examining the content of these programs, it was determined that autistic individuals are labelled vulnerable persons due to the perceived relationship between inherent autistic traits and behaviours and the risk of harm or victimisation when they are without the supervision of a caregiver. Study two analysed a subset of the programs promoted on official police services websites, Autism Registries, using the What is the Problem Represented to Be? framework for discourse analysis. From this analysis, the suggested problem solved by Autism Registries is the risk of harm and victimisation resulting from autistic traits and behaviour. Constructing autistic individuals this way in the materials for the Autism Registries reproduces ableist discourses, which suggest that these individuals are incapable of risk management and, therefore, should be relegated to the care of others. It also obscures the contributions of broader social conditions contributing to encounters between police and autistic individuals. Finally, in Study three, officers from seven police services across Ontario, Canada, were interviewed to understand how they conceptualised the vulnerability of autistic individuals and the role registry-based programs played in their encounters with them. Sampled police officers recognised that the vulnerability of autistic individuals was complex and resulted from multiple contributing variables. They described how registry-based programs could be used for search and rescue operations, navigating encounters requiring de-escalation, and justifying accommodations made to policies and procedures. Combined, the results from these studies suggest that registry-based programs in police services can benefit both officers and autistic individuals during crisis encounters; however, by focusing on these encounters, the broader social conditions that are contributing to elevated police contact in the first place are left unexamined and unaddressed. This includes ableist assumptions that contribute to stigma and discrimination towards autistic individuals and the austere government spending that has left the gaps in service for police to fill
