Putting the Pieces Together for Good Governance of REDD+: An Analysis of 32 REDD+ Country Readiness Proposals
Developing countries are receiving new financial and technical support to design and implement programs that reduce emissions from deforestation and forest degradation (referred to as REDD+). Reducing emissions from forest cover change requires transparent, accountable, inclusive, and coordinated systems and institutions to govern REDD+ programs. Two multilateral initiatives -- the World Bank-administered Forest Carbon Partnership Facility (FCPF) and the United Nations Collaborative Programme on Reducing Emissions from Deforestation and Forest Degradation in developing countries (UN-REDD Programme) -- are supporting REDD+ countries to become "ready" for REDD+ by preparing initial strategy proposals, developing institutions to manage REDD+ programs, and building capacity to implement REDD+ activities. This paper reviews 32 REDD+ readiness proposals submitted to these initiatives to understand overall trends in how eight elements of readiness (referred to in this paper as readiness needs) are being understood and prioritized globally. Specifically, we assess whether the readiness proposals (i) identify the eight readiness needs as relevant for REDD+, (ii) discuss challenges and options for addressing each need, and (iii) identify next steps to be implemented in relation to each need. Our analysis found that the readiness proposals make important commitments to developing effective, equitable, and well-governed REDD+ programs. However, in many of the proposals these general statements have not yet been translated into clear next steps
Characterization of P2P IPTV Traffic: Scaling Analysis
P2P IPTV applications arise on the Internet and will be massively used in the
future. It is expected that P2P IPTV will contribute to increase the overall
Internet traffic. In this context, it is important to measure the impact of P2P
IPTV on the networks and to characterize this traffic. Dur- ing the 2006 FIFA
World Cup, we performed an extensive measurement campaign. We measured network
traffic generated by broadcasting soc- cer games by the most popular P2P IPTV
applications, namely PPLive, PPStream, SOPCast and TVAnts. From the collected
data, we charac- terized the P2P IPTV traffic structure at different time
scales by using wavelet based transform method. To the best of our knowledge,
this is the first work, which presents a complete multiscale analysis of the
P2P IPTV traffic. Our results show that the scaling properties of the TCP
traffic present periodic behavior whereas the UDP traffic is stationary and
lead to long- range depedency characteristics. For all the applications, the
download traffic has different characteristics than the upload traffic. The
signaling traffic has a significant impact on the download traffic but it has
negligible impact on the upload. Both sides of the traffic and its granularity
has to be taken into account to design accurate P2P IPTV traffic models.Comment: 27p, submitted to a conferenc
Layered Steered SpaceâTime-Spreading-Aided Generalized MC DS-CDMA
AbstractâWe present a novel trifunctional multiple-inputâ multiple-output (MIMO) scheme that intrinsically amalgamates spaceâtime spreading (STS) to achieve a diversity gain and a Vertical Bell Labs layered spaceâtime (V-BLAST) scheme to attain a multiplexing gain in the context of generalized multicarrier direct-sequence code-division multiple access (MC DS-CDMA), as well as beamforming. Furthermore, the proposed system employs both time- and frequency-domain spreading to increase the number of users, which is also combined with a user-grouping technique to reduce the effects of multiuser interference
On Formal Methods for Collective Adaptive System Engineering. {Scalable Approximated, Spatial} Analysis Techniques. Extended Abstract
In this extended abstract a view on the role of Formal Methods in System
Engineering is briefly presented. Then two examples of useful analysis
techniques based on solid mathematical theories are discussed as well as the
software tools which have been built for supporting such techniques. The first
technique is Scalable Approximated Population DTMC Model-checking. The second
one is Spatial Model-checking for Closure Spaces. Both techniques have been
developed in the context of the EU funded project QUANTICOL.Comment: In Proceedings FORECAST 2016, arXiv:1607.0200
Multi-stakeholder design of forest governance and accountability arrangements in Equator province, Democratic Republic of Congo
Good forest governance is an increasingly important topic for stakeholders in many different settings around the world. Two of the best-known international initiatives to improve forest governance are the regional Forest Law Enforcement and Governance (FLEG) ministerial processes supported by the World Bank, and the European Unionâs Forest Law Enforcement, Governance and Trade (FLEGT) Action Plan. Designed to support and complement such initiatives, the IUCN project âStrengthening Voices for Better Choicesâ (SVBC) is piloting improved forest governance arrangements in six countries in Africa, Asia and South America. In the Democratic Republic of Congo (DRC), one of three project countries in Africa, SVBC has created multi-stakeholder platforms at local, territorial and provincial levels for this purpose

Designing for change: mash-up personal learning environments
Institutions for formal education and most work places are equipped today with at least some kind of tools that bring together people and content artefacts in learning activities to support them in constructing and processing information and knowledge. For almost half a century, science and practice have been discussing models on how to bring personalisation through digital means to these environments. Learning environments and their construction as well as maintenance makes up the most crucial part of the learning process and the desired learning outcomes and theories should take this into account. Instruction itself as the predominant paradigm has to step down.
The learning environment is an (if not 'theĂŻÂżÂœ) important outcome of a learning process, not just a stage to perform a 'learning play'. For these good reasons, we therefore consider instructional design theories to be flawed.
In this article we first clarify key concepts and assumptions for personalised learning environments. Afterwards, we summarise our critique on the contemporary models for personalised adaptive learning. Subsequently, we propose our alternative, i.e. the concept of a mash-up personal learning environment that provides adaptation mechanisms for learning environment construction and maintenance. The web application mash-up solution allows learners to reuse existing (web-based) tools plus services.
Our alternative, LISL is a design language model for creating, managing, maintaining, and learning about learning environment design; it is complemented by a proof of concept, the MUPPLE platform. We demonstrate this approach with a prototypical implementation and a â we think â comprehensible example. Finally, we round up the article with a discussion on possible extensions of this new model and open problems
Process Based Management and the Central Role of Dialogical Collective Activity in Organizational Learning. The Case of Work Safety in the Building Industry
The notion of âprocessâ, which describes the cooperation of heterogeneous practices and competences for a given output, has gained a major position in managerial practices for the last twenty years. This paper presents three ideas about organizational dynamics and processes and tests their applicability in the case of work safety improvement in a building company. The first idea is that the success of the process notion shows the central role of âconjointâ (as opposed to âcommonâ) collective activity in organizational learning. Conjoint collective activity is dialogical (âacts speakâ) and mediated by the utilization of semiotic systems (languages and technical and managerial tools). The second idea is that organizational learning is neither based on the actorsâ individual subjectivity nor on the technological and objective artefacts engaged in the processes, but rather on the reflexive understanding and ongoing redesign of processes by the process actors themselves, in the frame of a reflexive inquiry, a âcollective activity about collective activityâ which is triggered and kept in motion by axiological judgments (process evaluation). The third idea is that the possibilities to configure processes in a given organization are multiple. The reflexive inquiry enacts a specific social, spatial and time configuration of the process, its âchronotopeâ in Bakhtinâs vocabulary, which plays a major role in the way actors can make sense of their collective activity and transform it. A longitudinal case study about work safety on the building yards shows that it is difficult to âcontrol outâ risk at work once designs have been established, in the frame of the âproject executionâ process, but it is easier to âdesign outâ risk, when the actors of the process collectively design and redesign their collective activity, from the very first phases of a building project to the end. Therefore a major way to improve safety consists in extending the chronotope of the collective activity under consideration, overcoming the traditional separation between âdesign / planningâ and âexecutionâ. The conclusion summarizes the main theoretical, epistemological and practical issues involved in this research about conjoint collective activity.Business Process; Chronotope; Collective Activity; Collective Sense Making; Dialogism; Inquiry; Process-based Management; Safety Management
