This case study presents a country-wide quantitative analysis of a Parliamentary Commission established in 2012 in Myanmar to examine ‘land grab’ cases considered and to propose solutions towards releasing the land to its original owners, in most cases smallholder farming families. The study analyses the information contained in four reports released to the public, but also aims to elicit information they do not reveal. First of all, the paper suggests the commission has failed to provide detailed information about land grabs by the military. Second, the Commission seems to have targeted urban areas and urbanization projects and has underestimated land grab cases in rural areas. Third, by contrasting the locations of land confiscation cases with those of agro-industrial concessions as of 2011, the paper also shows how the Commission has evaded, rather than tackled, some very critical land confiscation issues driven by these concessions. Eventually, the authors argue for a mechanism that gathers, manages and releases relevant data on land confiscation and redistribution in a manner that allows for full disclosure. [less ▲]

For ensuring good practices in research from the beginning and developing a culture of ethics, ULg developed an integrated approach focusing on young researchers. The objective is to instill, as soon as possible, a good perception of what is quality in research, considering methodology, project management and ethics as norms and moral positioning for solving dilemma. Actions, coordinated by the Council for Ethics and Scientific Integrity (CEIS), are developed simultaneously through 5 axes. Young researchers are involved at all levels of the process, directly or as representative of the PhD Association. 1. Training: Sensitization and education to ethics; development of professional capacities, incl. data analysis & open data; seminaries with supervisors and PhDs ("duos") 2. Forum: ethics on the public space – Seminaries, conference, round tables, intervision, discussion and exchange on questions, dilemma, case-studies, with the help of external experts 3. Research appraisal: requirement for an ethics appraisal of each research project, with a special focus on human and social sciences, with the help of disciplinary ethics committees 4. Ethics analysis: Analysis of special questions, complains, problems, and decision making in case of violation of integrity 5. Regulation: Writing of procedures, dissemination of documents, recommendations and case-studies, link to the HR Strategy for researchers and the Charter and Code. In 2016, successful activities took place : - about 500 PhDs (25%) participated directly in the "Go2thesis training" (incl. 1 day on project management and ethics), dedicated trainings (introduction, special questions) and forum-debates - all the research projects, incl. PhD grants, supported by ULg were requested to provide an ethical issue check list, based on the H2020 standards. The R&D Office helped to explain about the issues and resources, and to orient the applicant to the ad hoc ethics committee - special requests were analyzed by the CEIS for several PhD's sensitive projects - Information was provided to PhDs regarding authorship, crowdfunding, privacy, open data and security while travelling New projects will be developed for (1) strengthening the relation between CEIS-ethics committee-doctoral school-supervisor-PhD (2) involving all the new PhDs in the training and forum, and (3) ensure the ethics appraisal during the whole duration of the PhD thesis (i.e. special chapter in the annual report). This presentation aims to exchange about what was done, the actual and expected impact of actions, what is going right and wrong, and how ULg is managing this dynamics as part of the HR Strategy for researchers project. A discussion with participants is expected on results and new projects. [less ▲]

Over the last couple of years, Beninese magistrates have gone on multiple strikes. Most of them complain about their substantial workload, low pay, and poor working conditions. They also highlight the discrepancies between the magistrates’ social status and what their families expect from them. While there seems to be a professional malaise within the Beninese bench, judges and prosecutors also insist on the importance of their work and the ethics that goes together with it. This is why we will be looking at the discourses and representations of the social and professional status of Beninese judges. Why do young lawyers choose the path of being a magistrate over other legal careers? How do judges and prosecutors in the Republic of Benin balance professional ethos with practical work routine?

The present study principally aims at determining to which extent prenatal exercise (before and during gestation) could affect the initiation (establishment) and the expression of psychomotor sensitization induced by a representative dose of cocaine in young female and male mice. More specifically, we will assess cocaine-induced acute psychomotor-activating effects, psychomotor sensitization developing over 9 daily sessions (daily peritoneal injections of cocaine or saline) and the long-term expression of the sensitized response (30 days after the last sensitizing injection) in C57BL/6J mice born from mothers housed with or without a running wheel before and during gestation. Based on literature and on our prior results, the mice born from exercised mothers are expected to show significantly reduced levels of cocaine responsiveness in comparison with the control mice (born from unexercised mothers).

In the era that huge numbers of microbial genomes are being released in the databases, it becomes increasingly important to rapidly mine genes as well as predict the regulatory networks that control their expression. To this end, we have developed an improved and online version of the PREDetector software aimed at identifying putative transcription factor-binding sites (TFBS) in bacterial genomes. The original philosophy of PREDetector 1.0 is maintained, i.e. to allow users to freely fix the DNA-motif screening parameters, and to provide a statistical means to estimate the reliability of the prediction output. This new version offers an interactive table as well as graphics to dynamically alter the main screening parameters with automatic update of the list of identified putative TFBS. PREDetector 2.0 also has the following additional options: (i) access to genome sequences from different databases, (ii) access to weight matrices from public repositories, (iii) visualization of the predicted hits in their genomic context, (iv) grouping of hits identified in the same upstream region, (v) possibility to store the performed jobs, and (vi) automated export of the results in various formats. PREDetector 2.0 is available at http://predetector.fsc.ulg.ac.be/. [less ▲]

We report the discovery of two transiting planetary systems: a super dense, sub-Jupiter mass planet WASP-86b (\mpl\ = 0.82 $\pm$ 0.06 \mj, \rpl\ = 0.63 $\pm$ 0.01 \rj), and a bloated, Saturn-like planet WASP-102b (\mpl\ = 0.62 $\pm$ 0.04 \mj, \rpl\=1.27 $\pm$ 0.03 \rj). They orbit their host star every $\sim$5.03, and $\sim$2.71 days, respectively. The planet hosting WASP-86 is a F7 star (\teff\ = 6330$\pm$110 K, \feh\ = $+$0.23 $\pm$ 0.14 dex, and age $\sim$0.8--1~Gyr), WASP-102 is a G0 star (\teff\ = 5940$\pm$140 K, \feh\ = $-$0.09$\pm$ 0.19 dex, and age $\sim$1~Gyr). These two systems highlight the diversity of planetary radii over similar masses for giant planets with masses between Saturn and Jupiter. WASP-102b shows a larger than model-predicted radius, indicating that the planet is receiving a strong incident flux which contributes to the inflation of its radius. On the other hand, with a density of $\rho_{pl}$ = 3.24$\pm$~0.3~$\rho_{jup}$, WASP-86b is the densest gas giant planet among planets with masses in the range 0.05 $<M$_{pl}$<$ 2.0 \mj. With a stellar mass of 1.34 M$_{\odot}$ and \feh = $+$0.23 dex, WASP-86 could host additional massive and dense planets given that its protoplanetary disc is expected to also have been enriched with heavy elements. In order to match WASP-86b's density, an extrapolation of theoretical models predicts a planet composition of more than 80\% in heavy elements (whether confined in a core or mixed in the envelope). This fraction corresponds to a core mass of approximately 210\me\ for WASP-86b's mass of \mpl$\sim$260\,\me. Only planets with masses larger than about 2\mj\ have larger densities than that of WASP-86b, making it exceptional in its mass range. [less ▲]

As evidenced by this randomized trial, thymectomy clearly improved clinical status of patients with nonthymomatous myasthenia gravis (MG) and this study ends a very long controversy about the interest of this surgical procedure mainly based on previous empirical observations. Although they are not discussed in this important paper, a series of experimental arguments reviewed in joint references argue for the idea that the clinical benefit of thymectomy is primarily due to the removal of the organ primarily implicated in MG pathophysiology. The thymus plays a central role in programming central immunological self-tolerance [1,2], and a thymus dysfunction is a primary event in the development of organ-specific autoimmunity [3,4]. It is therefore not surprising that the surgical removal of the primary 'sick' organ contributes to improve clinical outcomes and to reduce immunosuppressive therapy in MG patients. References: 1.

We predict a universal echo phenomenon present in the time evolution of many-body states of interacting quantum systems described by Fermi-Hubbard models. It consists of the coherent revival of transition probabilities echoing a sudden flip of the spins that, contrary to its single-particle (Hahn) version, is not dephased by interactions or spin-orbit coupling. The many-body spin echo signal has a universal shape independent of the interaction strength, and an amplitude and sign depending only on combinatorial relations between the number of particles and the number of applied spin flips. Our analytical predictions, based on semiclassical interfering amplitudes in Fock space associated with chaotic mean-field solutions, are tested against extensive numerical simulations confirming that the coherent origin of the echo lies in the existence of anti-unitary symmetries.

We report three newly discovered exoplanets from the SuperWASP survey. WASP-127b is a heavily inflated super-Neptune of mass 0.18Mj and radius 1.35Rj. This is one of the least massive planets discovered by the WASP project. It orbits a bright host star (V = 10.16) of spectral type G5 with a period of 4.17 days.WASP-127b is a low density planet which has an extended atmosphere with a scale height of 2500+/-400 km, making it an ideal candidate for transmission spectroscopy. WASP-136b and WASP-138b are both hot Jupiters with mass and radii of 1.51 Mj and 1.38 Rj, and 1.22 Mj and 1.09 Rj, respectively. WASP-136b is in a 5.22-day orbit around an F9 subgiant star with a mass of 1.41 Msun and a radius of 2.21 Rsun. The discovery of WASP-136b could help constraint the characteristics of the giant planet population around evolved stars. WASP-138b orbits an F7 star with a period of 3.63 days. Its radius agrees with theoretical values from standard models, suggesting the presence of a heavy element core with a mass of 10 Mearth. The discovery of these new planets helps in exploring the diverse compositional range of short-period planets, and will aid our understanding of the physical characteristics of both gas giants and low density planets.

When gently placing a droplet onto a vertically vibrated bath, a drop can bounce without coalescing. Upon increasing the forcing acceleration, the droplet is propelled by the wave it generates and becomes a walker with a well defined speed. We investigate the confinement of a walker in different rectangular cavities, used as waveguides for the Faraday waves emitted by successive droplet bounces. By studying the walker velocities, we discover that 1d confinement is optimal for narrow channels of width of D≃1.5λF. We also propose an analogy with waveguide models based on the observation of the Faraday instability within the channels. [less ▲]

From the Sahel to the coast, West Africa is experiencing a variety of climate change impacts, including sea level rise, soil salinization, floods, drought, and desertification, while simultaneously suffering from other forms of environmental degradation. Together, these environmental changes are significantly influencing migration patterns in and out of West Africa. This paper seeks to analyze vulnerability and resilience to environmental changes as they affect and are affected by mobility patterns in the region. We assert that the impact of environmental changes cannot be isolated from other political, social, economic, and demographic pressures that together drive human mobility. In a region where natural resources form the foundation of livelihoods and food security (fishing and agriculture), the relationship between environmental changes and socioeconomic vulnerabilities is of particular concern. This paper therefore draws from four distinct case studies to grasp the variegated and cumulative vulnerability and resilience among local populations as they relate to internal and intraregional migration.

Un article publié dans Land Use Policy début 2016 arrive à la conclusion a priori étonnante que la déforestation serait, au Congo, plus élevée dans les concessions forestières avec des plans d’aménagement que dans celles qui n’en ont pas. L’analyse d’évaluation d’impact qui a conduit ces chercheurs à un tel résultat se base sur un appariement de parcelles sélectionnées aléatoirement dans des concessions avec et sans plans d’aménagement. Ces chercheurs indiquent que le réseau de routes forestières plus développé dans les concessions aménagées serait un des facteurs explicatifs. L’autre facteur serait le développement local lié aux cahiers des charges des plans d’aménagement, lequel conduirait à une augmentation de la population dans ces concessions et à une déforestation accrue. Notre groupe d’une vingtaine de chercheurs connaissant bien la problématique de l’aménagement forestier en Afrique centrale s’est penché à son tour sur cette question et a analysé la déforestation au niveau des concessions sur le même intervalle de temps. Nos résultats montrent, cette fois, que la déforestation est moins importante dans les concessions avec un plan d’aménagement que dans les autres. Et si l’on compare à production égale la déforestation dans des concessions avec et sans plan d’aménagement, il apparaît que les UFA aménagées sont environ deux fois plus « efficaces », c’est-à-dire qu’on observe deux fois moins de perte de couvert forestier par mètre-cube produit. Nous en concluons qu’il est nécessaire d’analyser précisément la dynamique des différents facteurs de déforestation, et éviter d’imputer mécaniquement à l’aménagement forestier un rôle excessif dans l’évolution dans un sens ou dans l’autre du taux de déboisement. Enfin, toute évaluation doit rappeler que les effets de l’aménagement forestier doivent être mesurés sur le long terme : l’objectif de l’aménagement est de permettre une mise en valeur forestière durable, en conservant l’essentiel du capital productif pour éviter, autant que possible, la conversion à d’autres usages après les cycles de coupe initiaux.

Under SSPPU, the licensing rates paid to owners of SEPs for the use of their technology shall reflect the “value that the functionality of the claimed invention or inventive feature…contributes to the value of the relevant functionality of the smallest saleable Compliant Implementation that practices the Essential Patent Claim”. This paper reviews the SSPPU experiment through the lenses of the Coase theorem. It finds that SSPPU interferes with the efficient operation of the price system, and is likely to reduce investment in socially beneficial activities, including in General Purpose Technologies (“GPTs”) which are key drivers of economic growth.

Airlines use itinerary choice models to allocate the total number of passengers in a city pair to specific itineraries. In a related paper, we estimated a multinomial logit (MNL) itinerary choice model using database of more than 3 million tickets for Continental U.S. markets provided by the Airlines Reporting Corporation that accounted for price endogeneity. The size and comprehensiveness of our database allowed us to estimate highly refined continuous departure time of day preference curves that account for distance, direction of travel, the number of time zones traversed, departure day of week and itinerary type (outbound, inbound or one-way). This paper and accompanying Excel spreadsheet located at http://garrowlab.ce.gatech.edu contain the results of all model coefficients (including the 1260 time of day parameters) and summarize results in a series of ten figures. These highly-refined time of day preference curves can be used by airlines, researchers, and government organizations in the evaluation of demand-management and other policies. [less ▲]

La régionalisation de la Politique Fédérale des Grandes Villes, suite à la sixième réforme de l’Etat, fut une opportunité de s’interroger sur les objectifs et l’organisation d’une Politique de la Ville en Wallonie. Dans ce cadre, la note de recherche CPDT n°63 « Politique de la ville. Dynamisation des cœurs de ville » répond à la volonté du Gouvernement wallon de se doter d’une vision territoriale stratégique sur le long terme et est un premier pas vers la mise en place d’une politique de la ville intégrée en Wallonie. Cette note fait le point sur, d’une part, les différentes politiques et outils relatifs à la restructuration et à la dynamisation des tissus urbains, au sens large, établis au niveau régional, fédéral et européen et, d’autre part, les propositions et recommandations relatives à l’évolution du cadre actuel. Cette réflexion s’adresse évidemment aux acteurs concernés par les enjeux de gouvernance urbaine : les décideurs politiques, les villes et les communes mais concerne aussi le citoyen. [less ▲]

Cet article fait une analyse comparative des résultats économiques de la production rizicole durant la saison B 2014 dans les trois pays de la CEPGL qui sont la République Démocratique du Congo, le Rwanda et le Burundi. L’approche comparative permet de trouver les explications des différences des résultats en partie dans les politiques mises en oeuvre dans chaque pays. Les enquêtes ont été menées dans la plaine de la Ruzizi partagée entre les trois pays auprès de 240 producteurs du riz choisi à partir de la méthode des quotas sur la base d'une stratification des exploitations rizicoles. Dans le site congolais (où il est plus difficile d’accéder aux intrants et crédits), les coûts de production d’1kg de paddy sont les plus élevés avec une fonction de production y=0,034x+0,053z+0,422 et le rendement le plus bas (2698kgs). Par contre, dans les sites burundais et rwandais où l’Etat intervient dans l’approvisionnement en intrants et particulièrement dans le site rwandais, l’accès aux crédits, les fonctions de production sont respectivement de y=0,024x+0,031z+0,297 et y=0,017x+0,023z+0,269 avec des rendements de 3962kgs et 5339kgs dans le même ordre. Les coûts de production supportés sur un hectare rizicole ou encore pour la production d’une tonne de paddy varient selon le pays car ils dépendent de la valeur des intrants utilisés et des autres charges de structures. Ils varient ainsi de 1139,4USD à 1354,5USD/ ha et de 269 à 422USD/tonne. [less ▲]

We study retirement incentives with augmented option value model à la Stock and Wise (1990). We propose methodological extensions to better reflect the respective incentives faced by singles and couples. Our results show that a more comprehensive modelling of couples’ incentives leads to very different patterns of retirement incentives – particularly for women. We apply the new indicators to data from the Survey of Health, Ageing and retirement in Europe (SHARE) in Belgium and find two key results. First, contrary to several previous studies, we obtain a positive signed income effects. Second, we find very different retirement incentives for men and women, with little flexibility in the retirement decision for men and substantially more flexibility for women as a function of financial incentives and household composition.

Enthused by China’s conversion to the free market system in 1978 and its adoption of Western-style market institutions, the world has spent the last few decades turning a blind eye to China’s real “governance” problem: that a shadow Party-State system permeates all branches of the economy. Whatever Washington-consensus style institutions are put in place, whatever State Owned Enterprise (“SOE”) reform is introduced, corporate and market governance occur under the rule of the Chinese Communist Party (“CCP”). And the CCP’s guidebook is the Leninist command that the whole of society shall be run as “single country-wide State syndicate”. This paper contends that China’s syndicated economic organization is akin to a “supertrust”, and that this creates conditions that are conducive to antitrust problems to which the Western world must awaken. In this context, this paper advances that the antitrust regulators of North America, Europe and elsewhere should take two simple, pragmatic steps under merger control and antitrust rules. In merger review, antitrust agencies should treat all SOEs and Privately Owned Enterprises (POEs) with a CCP cell as one unitary group and undertake a thorough competitive assessment of transactions on this basis. In addition, antitrust cases involving Chinese firms should be investigated on the default assumption that there is an underlying coordination scheme among them. [less ▲]

We propose a simple but fundamental methodological change to Fama and French (1993) factor construction procedure. Consistent with Lambert and Hübner (2013) sequential sorting procedure to classify stocks, our methodology controls ex ante for pricing errors produced by multifactor models. Our size and value factors deliver less specification errors when used to price portfolios, especially regarding low size and high B/M stocks. Furthermore, this alternative framework generates much stronger “turn-of-the-year” size and “through-the-year” book-to-market effects than conventionally documented. The factors also display a slight competitive advantage on the taxonomy of low turnover market anomalies defined by Novy-Marx and Velikov (2015). [less ▲]

This paper clarifies the path that Rwanda took in the quest for a modern, intensive, productive and market-oriented agriculture. The facts presented here have been collected by means of documentation that led to the review of different publications including published papers and government and development partners’ reports. The paper shows that an adequate policy and institutional environment has been created by various socio-economic, institutional and agriculture-led reforms launched since the early 2000s. The literature review reveals that impressive results have been recorded in regard to smallholder agriculture intensification. In addition, the theoretical model for progressive smallholder agriculture transformation helped to show that most of the smallholders grouped in cooperatives are at the 'semi-commercial smallholders' stage while only a few are at the 'commercial smallholders' and 'advanced farmers' stages. This study also examines various challenges that hamper the sustainable intensification of smallholder agriculture at both institutional, community and smallholder level. It suggests some policy actions to be put forward by the government and other agriculture sector development partners to address those challenges. [less ▲]

Long-term care (LTC) needs are expected to rapidly increase in the next decades and at the same time the main provider of LTC, namely the family is stalling. This calls for more involvement of the state that today covers less than 20% of these needs and most often in an inconsistent way. Besides the need to help the poor dependent, there is a mounting concern in the middlec lass that a number of dependent people are incurring costs that could force them to sell all their assets. In this paper we study the design of a social insurance that meets this concern. Following Arrow (1963), we suggest a policy that is characterized by complete insurance above a deductible amount.

We study the implications of the premise that any new, relativistic, highly energetic neutral particle that interacts with quarks and gluons would create cascade-like events in the IceCube (IC) detector which would be observationally indistinguishable from neutral current deep-inelastic (DIS) scattering events due to neutrinos. Consequently, one reason for deviations, breaks or excesses in the expected astrophysical power-law neutrino spectrum could be the flux of such a particle. Motivated by features in the recent 1347-day IceCube high energy starting event (HESE) data, we focus on particular boosted dark matter ($\chi$) related realizations of this premise, where $\chi$ is assumed to be much lighter than, and the result of, the slow decay of a massive scalar ($\phi $) which constitutes a major fraction of the Universe's dark matter (DM). We show that this hypothesis, coupled with a standard power-law astrophysical neutrino flux is capable of providing very good fits to the present data, along with a possible explanation of other features in the HESE sample: i.e., a) the paucity of events beyond $\sim 2$ PeV b) a spectral feature resembling a dip in the 400 TeV--1 PeV region and c) an excess in the $50-100$ TeV region. We consider two different boosted DM scenarios, and determine the allowed mass ranges and couplings for four different types of mediators (scalar, pseudoscalar, vector and axial-vector) which could connect the standard and dark sectors, imposing constraints from gamma-ray observations and collider searches. We find that the gamma-ray observations provide the most restrictive constraints, disfavouring the $1\sigma$ allowed parameter space from IC fits, while still being consistent with the $3\sigma$ allowed region. We also test our proposal and its implications against the sample of six year through-going muon track data recently released by IceCube. [less ▲]

Accessing the connection between classical chaos and quantum many-body systems has been a long-standing experimental challenge. Here, we investigate the onset of chaos in periodically driven two-component Bose-Einstein condensates, whose small quantum uncertainties allow for exploring the phase space with high resolution. By analyzing the uncertainties of time-evolved many-body states, we find signatures of elliptic and hyperbolic periodic orbits generated according to the Poincar\'e-Birkhoff theorem, and the formation of a chaotic region at increasing driving strengths. The employed fluctuation analysis allows for probing the phase-space structure by use of only short-time quantum dynamics. [less ▲]

The purpose of this HST white paper is to demonstrate that it is possible to monitor Jupiter’s polar haze with HST/STIS without breaking the ground screening limit for bright objects. This demonstration rests on a thorough simulation of STIS output from an existing image obtained with HST/WFPC2. It is shown that the STIS NUV-MAMA + F25CIII filter assembly provides a count rate per pixel ~11 times smaller than that obtained for one pixel of WFPC2 WF3 CCD + F218W corresponding filter. This ratio is sufficiently large to cope with the bright solar light scattered by Jupiter’s atmosphere, which was a lesser concern for WFPC2 CCD safety. These STIS images would provide unprecedented spatial and temporal resolution observations of small-scale stratospheric aerosol structures, possibly associated with Jupiter’s complex FUV aurora.

This work studies path planning in two-dimensional space, in the presence of polygonal obstacles. We specifically address the problem of building a roadmap graph, that is, an abstract representation of all the paths that can potentially be followed around a given set of obstacles. Our solution consists in an original refinement algorithm for constrained Delaunay triangulations, aimed at generating a roadmap graph suited for planning paths with arbitrary clearance. In other words, a minimum distance to the obstacles can be specified, and the graph does not have to be recomputed if this distance is modified. Compared to other solutions, our approach has the advantage of being simpler, as well as significantly more efficient. [less ▲]

In 2016, the NASA Juno spacecraft will initiate its one-year mission around Jupiter and become the first probe to explore the polar regions of Jupiter. The HST UV instruments (STIS and ACS) can greatly contribute to the success of the Juno mission by providing key complementary views of Jupiter’s UV aurora from Earth orbit. Juno carries an ultraviolet Spectrograph (UVS) and an infrared spectral mapper (JIRAM) that will obtain high-resolution spectral images providing the auroral counterpart to Juno’s in situ particles and fields measurements with the plasma JADE and JEDI particle detectors. The Juno mission will be the first opportunity to measure simultaneously the energetic particles at high latitude and the auroral emissions they produce. Following programmatic and technical limitations, the amount of UVS data transmitted to Earth will be severely restricted. Therefore, it is of extreme importance that HST captures as much additional information as possible on Jupiter’s UV aurora during the one-year life of the Juno mission. This white paper is a plea for a “Juno initiative” that will ensure that a sufficient number of orbits is allocated to this unique solar system mission. [less ▲]

This paper studies path synthesis for nonholonomic mobile robots moving in two-dimensional space. We first address the problem of interpolating paths expressed as sequences of straight line segments, such as those produced by some planning algorithms, into smooth curves that can be followed without stopping. Our solution has the advantage of being simpler than other existing approaches, and has a low computational cost that allows a real-time implementation. It produces discretized paths on which curvature and variation of curvature are bounded at all points, and preserves obstacle clearance. Then, we consider the problem of computing a time-optimal speed profile for such paths. We introduce an algorithm that solves this problem in linear time, and that is able to take into account a broader class of physical constraints than other solutions. Our contributions have been implemented and evaluated in the framework of the Eurobot contest. [less ▲]

The issue of passive and active electoral rights in Bolivia has gone through various phases that are examined in details in this article. Universal suffrage in Bolivia occurred around the same time as in most states in that region: in the middle of the 20th century. The next wave of reforms occurred during the 1980s when dictatorships were removed from power. At that time, processes of democratization intensified in Bolivia and other parts of Latin America, eventually leading to the progressive strengthening of democratic institutions. It is really during the 1990s and early 2000s that the most important democratic transformations occurred. Major institutional reforms were passed during this period in particular to increase the participation of women and indigenous peoples in public affairs. The inclusion of the principles of gender equality and interculturality in the new constitution of 2009 is one of the clearest sign of this new approach. Similarly, another sector of the Bolivian population that had been traditionally prevented from exercising political rights. that is, Bolivians residing abroad have been closely attended to by the Evo Morales government since 2006. After the first external voting experience in 2009, the system was once again reformed to enable greater participation from abroad in the 2014 presidential election. These elements confirm that the extension of political rights in Bolivia is a process that has gone trough major changes over the past two decades but remains a work in process. [less ▲]
