The impact of Participatory Budgeting on health and wellbeing:A scoping review of evaluations
Background: Participatory budgeting (PB), citizens deliberating among themselves and with officials to decide how
to allocate funds for public goods, has been increasingly implemented across Europe and worldwide. While PB is
recommended as good practice by the World Bank and the United Nations, with potential to improve health and
wellbeing, it is unclear what evaluations have been conducted on the impact of PB on health and wellbeing.
Methods: For this scoping review, we searched 21 databases with no restrictions on publication date or language.
The search term âparticipatory budgetâ was used as the relevant global label for the intervention of interest. Studies
were included if they reported original analysis of health, social, political, or economic and budgetary outcomes of
PB. We examined the study design, analysis, outcomes and location of included articles. Findings are reported
narratively.
Results: From 1458 identified references, 37 studies were included. The majority of evaluations (n = 24) were of PB
in South America, seven were in Europe. Most evaluations were case studies (n = 23) conducting ethnography and
surveys, focussing on political outcomes such as participation in PB or impacts on political activities. All of the
quantitative observational studies analysing population level data, except one in Russia, were conducted in South
America.
Conclusion: Despite increasing interest in PB, evaluations applying robust methods to analyse health and
wellbeing outcomes are scarce, particularly beyond Brazil. Therefore, implementation of PB schemes should be
accompanied by rigorous qualitative and quantitative evaluation to identify impacts and the processes by which
they are realised
Multidimensional simple waves in fully relativistic fluids
A special version of multi--dimensional simple waves given in [G. Boillat,
{\it J. Math. Phys.} {\bf 11}, 1482-3 (1970)] and [G.M. Webb, R. Ratkiewicz, M.
Brio and G.P. Zank, {\it J. Plasma Phys.} {\bf 59}, 417-460 (1998)] is employed
for fully relativistic fluid and plasma flows. Three essential modes: vortex,
entropy and sound modes are derived where each of them is different from its
nonrelativistic analogue. Vortex and entropy modes are formally solved in both
the laboratory frame and the wave frame (co-moving with the wave front) while
the sound mode is formally solved only in the wave frame at ultra-relativistic
temperatures. In addition, the surface which is the boundary between the
permitted and forbidden regions of the solution is introduced and determined.
Finally a symmetry analysis is performed for the vortex mode equation up to
both point and contact transformations. Fundamental invariants and a form of
general solutions of point transformations along with some specific examples
are also derived.Comment: 21 page
City rankings and the citizens: exposing representational and participatory gaps
Acritical reflection on the purposes, role and performance of city rankings through an holistic communicational approach is at the core of this article. Grounded on a conceptual framework that highlights the contemporary idea of the cityâbeyond the smart city and more as a co-intelligent, collaborative and co-creative entity, and on the performance outputs of city rankings as territorial and strategic communication tools that actually represent the state of cities, we address the citizensâ presence or contributeâas main city stakeholdersâto city rankings. In order to make research tangible with a practical component, an exploratory comparative content analysis of three recognized city rankings: the CBI â City Brands Index 2017, the GCR â 2018 Global Cities Report, and the Global Liveability Index 2018âwas carried out. Conclusive notes argue that in order to effectively represent cities, as they are lived, thought and built by their citizens in their everyday, city rankings must rely in more real-time, updated, peopleâs perception centred data, and embed more citizen participation and insights. Moreover, methodology transparency and accountability should be promoted in order to add trust value to city rankings.(undefined
Agricultura orgĂąnica em ĂĄreas urbanas e periurbanas com base na agroecologia.
A agricultura orgĂąnica com base na agroecologia Ă© o mote tecnolĂłgico adequado Ă realidade dos agroecossistemas urbanos. Este artigo ressalta a necessidade de se desenvolver tecnologias e insumos especĂficos. A partir de experiĂȘncias com agricultura urbana em diferentes paĂses em desenvolvimento, evidencia-se a necessidade de se buscar capacidades locais e apoio do poder pĂșblico, especialmente nas iniciativas da sociedade organizada e mobilizada para a produção agrĂcola urbana
Weak and strong solutions of equations of compressible magnetohydrodynamics
International audienceThis article proposes a review of the analysis of the system of magnetohydrodynamics (MHD). First, we give an account of the modelling asumptions. Then, the results of existence of weak solutions, using the notion of renormalized solutions. Then, existence of strong solutions in the neighbourhood of equilibrium states is reviewed, in particular with the method of Kawashima and Shizuta. Finally, the special case of dimension one is highlighted : the use of Lagrangian coordinates gives a simpler system, which is solved by standard techniques
