Saber hacer y hacer saber : la difusion de las innovaciones para la construccion de vivienda popular
Produire durablement du lait avec des chĂšvres en forĂȘt mĂ©diterranĂ©enne
Depuis, 2008, un RĂ©seau caprin pastoral mĂ©diterranĂ©en sâest constituĂ© entre services pastoraux de Provence-Alpes-CĂŽte dâAzur, Languedoc-Roussillon et Corse afin de rĂ©nover les rĂ©fĂ©rences de la valorisation des parcours par les chĂšvres. En rĂ©gion mĂ©diterranĂ©enne, les troupeaux caprins se dĂ©ploient largement dans la « forĂȘt mĂ©diterranĂ©enne », cette mosaĂŻque de taillis, de clairiĂšres, de garrigues ou de maquis qui leur fournissent une abondante ressource ligneuse. La contribution des parcours Ă la ration du troupeau peut alors atteindre jusquâĂ 80 % de lâalimentation annuelle : lâĂ©levage caprin transforme, littĂ©ralement, la broussaille en fromage. Les suivis rĂ©alisĂ©s sur une douzaine de fermes de rĂ©fĂ©rence montrent quâun pĂąturage prudent conduit en gardiennage permet un renouvellement durable de la strate arbustive de 0,4 m Ă 1,5 m de hauteur fournissant lâessentiel du pĂąturage des chĂšvres. A lâinverse, il est possible aussi dâobtenir un impact trĂšs fort qui tend Ă Ă©puiser les arbustes dans un objectif de dĂ©broussaillement. Ainsi câest par un pilotage prĂ©cis, diffĂ©renciĂ© selon les objectifs, en partenariat avec les gestionnaires de la forĂȘt, que lâĂ©levage caprin peut rĂ©investir la forĂȘt mĂ©diterranĂ©enne, cette fois en accord, et parfois Ă la demande, des forestiers
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
Turning Ideas into Proposals : A Case for Blended Participation During the Participatory Budgeting Trial in Helsinki
Balancing between online-offline stages of participatory procedures is a delicate art that may support or hinder the success of participatory democracy. Participatory budgeting (PB), in particular, is generally rooted in online platforms, but as our case study on the City of Helsinki PB trial suggests, face-to-face events are necessary to engage targeted and often less resourceful actors in the process. Based on a longer-term participant observation, covering the PB process from its early to ideation phase to the current stage of proposal development for the final vote, we argue that the process has thus far been successful in blending online-offline components, largely supported by the active support of borough liaisons who have served as navigators between the different stages. From the point of view of co-creation, different stages of the PB process (ideation, co-creation) call for different strategies of online-offline participation. Effective mobilization of marginalized actors and interactions between public servants and citizens seem to benefit from face-to-face processes, while city-wide voting and discussion can effectively occur in the online platform.Peer reviewe
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
Global solutions to the three-dimensional full compressible magnetohydrodynamic flows
The equations of the three-dimensional viscous, compressible, and heat
conducting magnetohydrodynamic flows are considered in a bounded domain. The
viscosity coefficients and heat conductivity can depend on the temperature. A
solution to the initial-boundary value problem is constructed through an
approximation scheme and a weak convergence method. The existence of a global
variational weak solution to the three-dimensional full magnetohydrodynamic
equations with large data is established
