Multilevel stakeholder influence mapping in climate change adaptation regimes
The extent to which any policy, planning, or funding frameworks aimed at supporting climate change adaptation contribute to improved adaptive capacity of smallholder farmers is strongly affected by the power/influence dynamics between actors within those regimes. Power and influence studies have renewed relevance due to the current proliferation of adaptation initiatives. As these initiatives evolve, they bring up questions of equity, justice, and fairness surrounding the origins and distribution of adaptation resources. In doing so, they have shed light on persistent inequalities in status quo development regimes and asymmetrical power balances between stakeholders.
To avoid exacerbating inequalities that contribute to conflict, perpetuate cycles of poverty, and prevent much needed resources from reaching vulnerable communities, it is essential that practitioners seek to make power/influence relationships transparent within any given adaptation regime. Exposing and characterizing these relationships is complex, sensitive, and involves multiple perspectives. This paper introduces the Multilevel Stakeholder Influence Mapping (MSIM) tool, which aims to assist analysts in the study of power dynamics across levels within climate adaptation regimes.
The tool is adapted from the Stakeholder Influence-Mapping tool (2005) of the International Institute for Environment and Development (IIED). MSIM is a simple visual tool to examine and display the relative power/influence that different individuals and groups have over a focal issueâin this case, climate change adaptation of smallholder farmers. The tool can be applied individually or in groups, as often as desired, to capture multiple perspectives and also to act as an intermediary object facilitating expression of sensitive information. The multilevel adapted version of the tool was trialed with a cross-section of actors in Nepalâs agricultural climate change adaptation regime. The results of this pilot, the tool use guidelines, and triangulation with supporting methods, as well as forward-looking applications in climate adaptation are provided herein
Community-based adaptation costing: An integrated framework for the participatory costing of community-based adaptations to climate change in agriculture
Understanding the cost associated with climate change adaptation interventions in agriculture is
important for mobilizing institutional support and providing timely resources to improve
resilience and adaptive capacities. Top-down national estimates of adaptation costs carry a risk
of mismatching the availability of funds with what is actually required on the ground.
Consequently, global and national policies require credible evidence from the local level, taking
into account microeconomic dynamics and community-appropriate adaptation strategies. These
bottom-up studies will improve adaptation planning (the how) and will also serve to inform and
validate top-down assessments of the total costs of adaptation (the how much).
Participatory Social Return on Investment (PSROI) seeks to provide a pragmatic, local-level
planning and costing framework suitable for replication by government and civil society
organizations. The âPSROI Frameworkâ is designed around a participatory workshop for
prioritizing and planning community-based adaptation (CBA) strategies, followed by an
analysis of the economic, social and environmental impacts of the priority measures using a
novel cost-benefit analysis framework.
The PSROI framework has been applied in three separate pilot initiatives in Kochiel and
Othidhe, Kenya, and Dodji, Senegal. This working paper seeks to outline the theoretical and
methodological foundations of the PSROI framework, provide case-study results from each
pilot study, and assess the strengths and weaknesses of the framework according to its
robustness, effectiveness and scalabilit
Classification of Static Charged Black Holes in Higher Dimensions
The uniqueness theorem for static charged higher dimensional black hole
containing an asymptotically flat spacelike hypersurface with compact interior
and with both degenerate and non-degenerate components of event horizon is
proposed. By studies of the near-horizon geometry of degenerate horizons one
was able to eliminate the previous restriction concerning the inequality
fulfilled by the charges of the adequate components of the aforementioned
horizons.Comment: 9 pages, RevTex, to be published in Phys.Rev. D1
On the Topology of Black Hole Event Horizons in Higher Dimensions
In four dimensions the topology of the event horizon of an asymptotically
flat stationary black hole is uniquely determined to be the two-sphere .
We consider the topology of event horizons in higher dimensions. First, we
reconsider Hawking's theorem and show that the integrated Ricci scalar
curvature with respect to the induced metric on the event horizon is positive
also in higher dimensions. Using this and Thurston's geometric types
classification of three-manifolds, we find that the only possible geometric
types of event horizons in five dimensions are and . In
six dimensions we use the requirement that the horizon is cobordant to a
four-sphere (topological censorship), Friedman's classification of topological
four-manifolds and Donaldson's results on smooth four-manifolds, and show that
simply connected event horizons are homeomorphic to or .
We find allowed non-simply connected event horizons and
, and event horizons with finite non-abelian first homotopy
group, whose universal cover is . Finally, following Smale's results we
discuss the classification in dimensions higher than six.Comment: 12 pages, minor edits 27/09/0
Topology Change of Coalescing Black Holes on Eguchi-Hanson Space
We construct multi-black hole solutions in the five-dimensional
Einstein-Maxwell theory with a positive cosmological constant on the
Eguchi-Hanson space, which is an asymptotically locally Euclidean space. The
solutions describe the physical process such that two black holes with the
topology of S^3 coalesce into a single black hole with the topology of the lens
space L(2;1)=S^3/Z_2. We discuss how the area of the single black hole after
the coalescence depends on the topology of the horizon.Comment: 10 pages, Some comments are added. to be published as a letter in

Crisis-flagged Misdemeanors in Seattle: Arrests, Referrals, Charges, and Case Dispositions
Objective: to study the features of misdemeanor arrests, charges, referrals, and case dispositions of behavioral crisis-flagged incidents in the largest city in the US north-west - Seattle.Methods: the study employs a quasi-experimental design to examine misdemeanor arrests, charges, referrals, and case dispositions of behavioral crisis-flagged incidents to better understand how individuals who are experiencing behavioral crisis are processed through the misdemeanor justice system. A sample of 505 cases of behavioral-crisis flagged incidents in Seattle from 2016-2018 are compared with a matched random sample of 1053 non-crisis cases examining similarities and differences in arrest, referral, charges, and case disposition.Results: misdemeanor offenses often involve individuals experiencing behavioral crises such as mental illness, drug and alcohol addiction, and homelessness. Little is known about how individuals in behavioral crisis arrested for misdemeanors are processed through the criminal justice system. In 2015, the Seattle Police Department implemented a Crisis Intervention Policy that employed a crisis template enabling systematic identifi of incidents fl by law enforcement as involving âbehavioral crisisâ to improve data collection and police response to incidents involving individuals in behavioral crisis. Implications for crisis intervention, case processing, and managing individuals who commit misdemeanors while in behavioral crisis are discussed. Scientific novelty: for the first time, the work substantiated the conclusion that individuals involved in crisis-flagged incidents are arrested at a consistently higher rate; are more likely to be charged, taken into custody, and incarcerated; and are more likely to be female.Practical significance: the main provisions and conclusions of the article can be used in scientific, pedagogical and law enforcement activities when considering the issues related to prevention and elimination crimes
Expansion in SL_d(Z/qZ), q arbitrary
Let S be a fixed finite symmetric subset of SL_d(Z), and assume that it
generates a Zariski-dense subgroup G. We show that the Cayley graphs of pi_q(G)
with respect to the generating set pi_q(S) form a family of expanders, where
pi_q is the projection map Z->Z/qZ
On the Gannon-Lee Singularity Theorem in Higher Dimensions
The Gannon-Lee singularity theorems give well-known restrictions on the
spatial topology of singularity-free (i.e., nonspacelike geodesically
complete), globally hyperbolic spacetimes. In this paper, we revisit these
classic results in the light of recent developments, especially the failure in
higher dimensions of a celebrated theorem by Hawking on the topology of black
hole horizons. The global hyperbolicity requirement is weakened, and we expand
the scope of the main results to allow for the richer variety of spatial
topologies which are likely to occur in higher-dimensional spacetimes.Comment: 13 pages, no figures, to appear in Class. Quantum Gra
Charged Rotating Kaluza-Klein Black Holes Generated by G2(2) Transformation
Applying the G_{2(2)} generating technique for minimal D=5 supergravity to
the Rasheed black hole solution, we present a new rotating charged Kaluza-Klein
black hole solution to the five-dimensional Einstein-Maxwell-Chern-Simons
equations. At infinity, our solution behaves as a four-dimensional flat
spacetime with a compact extra dimension and hence describes a Kaluza-Klein
black hole. In particlar, the extreme solution is non-supersymmetric, which is
contrast to a static case. Our solution has the limits to the asymptotically
flat charged rotating black hole solution and a new charged rotating black
string solution.Comment: 24 page
Expansion in perfect groups
Let Ga be a subgroup of GL_d(Q) generated by a finite symmetric set S. For an
integer q, denote by Ga_q the subgroup of Ga consisting of the elements that
project to the unit element mod q. We prove that the Cayley graphs of Ga/Ga_q
with respect to the generating set S form a family of expanders when q ranges
over square-free integers with large prime divisors if and only if the
connected component of the Zariski-closure of Ga is perfect.Comment: 62 pages, no figures, revision based on referee's comments: new ideas
