description: Studies of the relationships between property rights and technology adoption are complicated in several respects. First, there are challenges involved in defining and measuring property rights and tenure security. Second, there are several different valid purposes for undertaking such studies and each purpose may require a different approach. Third, there are a number of difficult theoretical and empirical issues involved in such studies, particularly in defining technology, identifying key dimensions of property rights, and accounting for the endogeneous determination of property rights. Through a synthesis and evaluation of previous studies, this paper identifies key issues and develops guidelines for conducting research on the relationships between property rights and technology adoption in smallholder agriculture. It seeks to benefit researchers and policy makers wishing to undertake or interpret empirical research. The topics addressed in the paper are: definition of scope and terms; key issues pertaining to the relationships between technology adoption and property rights variables; data collection and measurement issues; and analyses and interpretation of findings. The primary target groups for this paper are researchers and policy analysts.

A novel method for measuring electric field induced dipole moments of metal-dielectric Janus particles in nematic liquid crystals

description: Janus particles are special types of nano or micro particles possessing at least two surfaces with distinct physical or chemical properties. The most studied Janus particles are the metal-dielectric particles, in which half surface of dielectric particles is coated with a very thin layer of metals. The external electric field induces dipole moment, and consequently the particles exhibit self-assembled dynamic structures in concentrated aqueous suspensions. Here, we study metal-dielectric Janus particles in a nematic liquid crystal under AC electric field and demonstrate a novel method for measuring effective induced dipole moments of the particles, through competition between elastic and electrostatic (Coulomb) forces of the two particles. The calculated polarisability of the particles based on a simple model agrees well with the effective polarisability measured in the experiments. Our findings have important bearing on functional materials based on metal-dielectric Janus particles dispersed in an anisotropic medium.

description: The increasing of experimental observations' accuracy and model complexity requires the development of a new class of numerical solvers. In this work, we present a GPU-accelerated approach for solving the Parker equation in the heliosphere using a stochastic differential equation (SDE) approach. The presented method was applied to a generic system of SDE using the CUDA programming language. Our approach achieves significant speedup compared to a CPU implementation, allowing us to efficiently solve for the modulated spectra of charged particles in the heliosphere. We demonstrate the accuracy and efficiency of our method through numerical experiments on a realistic model of the heliosphere.

description: To understand the mechanism of TATA-box conformational transformations we model structure mobility and find the types of conformational excitations of DNA macromolecule in heteronomous conformation. We have constructed the two-component model for describing DNA conformational transformation with simultaneous transitions in the furanos rings of the monomer link. Internal component describes the change of the base pair position in the double helix. External component describes the displacement of mass center of the monomer link. Nonlinearity of the system is accounted with a form of potential energy describing C3'-C2' and C2'-C3' sugars transitions in monomer link, and interrelation between monomer conformational transition and macromolecule deformation. The comparison of our results with experimental data allows to confirm that the localized conformational excitations may realise in DNA TATA-box. These excitations cause the deformation of the macromolecule fragment.

description: Many watershed development projects around the world have performed poorly because they failed to take into account the needs, constraints, and practices of local people. Participatory watershed management—in which users help to define problems, set priorities, select technologies and policies, and monitor and evaluate impacts—is expected to improve performance. User participation in watershed management raises new questions for watershed research, including how to design appropriate mechanisms for organizing stakeholders and facilitating collective action. Management of a complex system such as a watershed may also require user participation in the research process itself. An increasing number of watershed research projects are already participatory, however challenges remain to institutionalizing user participation in both watershed management and research.

description: V617 Sgr is a V Sagittae star - a group of binaries thought to be the galactic counterparts of the Compact Binary Supersoft X-ray Sources - CBSS. To check this hypothesis, we measured the time derivative of its orbital period. Observed timings of eclipse minima spanning over 30,000 orbital cycles are presented. We found that the orbital period evolves quite rapidly: P/Pdot = 1.1 x 10^{6} years. This is consistent with the idea that V617 Sgr is a wind driven accretion supersoft source. As the binary system evolves with a time-scale of about one million years, which is extremely short for a low mass evolved binary, it is likely that the system will soon end either by having its secondary completely evaporated or by the primary exploding as a supernova of type Ia.

description: We introduce a new quantum Rényi divergence $D^{\#}_α$ for $α\in (1,\infty)$ defined in terms of a convex optimization program. This divergence has several desirable computational and operational properties such as an efficient semidefinite programming representation for states and channels, and a chain rule property. An important property of this new divergence is that its regularization is equal to the sandwiched (also known as the minimal) quantum Rényi divergence. This allows us to prove several results. First, we use it to get a converging hierarchy of upper bounds on the regularized sandwiched $α$-Rényi divergence between quantum channels for $α> 1$. Second it allows us to prove a chain rule property for the sandwiched $α$-Rényi divergence for $α> 1$ which we use to characterize the strong converse exponent for channel discrimination. Finally it allows us to get improved bounds on quantum channel capacities.

description: In the arid and semi-arid Indian state of Rajasthan, tanks and ponds have been a mainstay of rural communities for centuries. There are over 4600 large minor irrigation tanks, plus numerous johads, bandhs and pals (small water harvesting structures). This paper assesses a strategy proposed for rehabilitating 1200 of the larger tanks. It argues that treating tanks only as flow irrigation systems—which lies at the center of the mainstream thinking on rehabilitating surface irrigation systems--is very likely to result in a flawed strategy when applied to tanks. Instead, reviewing the successful experience of NGOs like PRADAN and Tarun Bharat Sangh in reviving and rehabilitating clusters of small traditional water harvesting structures at a watershed level, it posits that Rajasthan’s tanks belong more to the watershed development domain than to the irrigation domain and that a strategy that views tanks as multi-use socio-ecological constructs, and which recognizes varied stakeholder groups is more likely to enhance the social value of tanks.

description: The open electron resonator, described by Duncan et.al, is a mesoscopic device that has attracted considerable attention due to its remarkable behaviour (conductance oscillations), which has been explained by detailed theories based on the behaviour of electrons at the top of the Fermi sea. In this work, we study the resonator using the simple quantum quantum electrical circuit approach, developed recently by Li and Chen. With this approach, and considering a very simple capacitor-like model of the system, we are able to theoretically reproduce the observed conductance oscillations. A very remarkable feature of the simple theory developed here is the fact that the predictions depend mostly on very general facts, namely, the discrete nature of electric charge and quantum mechanics; other detailed features of the systems described enter as parameters of the system, such as capacities and inductances.

description: This paper presents a detailed description of the applied methodology used to study collective action in natural resource management (NRM). Data were collected in 48 villages in northeastern Burkina Faso, at the community, institutional, household and market levels. The paper first discusses the analytical framework underlying the study of collective action, and then describes in detail the methods used to measure collective action and community-level cooperative capacity, and the determinants of cooperative capacity. We also describe data collection methods as well as potential problems in eliciting unbiased information. The impact of cooperative capacity on a variety of outcomes observed at both the community and household level is then presented in order to highlight practical applications.

description: Complex systems are large collections of entities that organize themselves into non-trivial structures that can be represented by networks. A key emergent property of such systems is robustness against random failures or targeted attacks ---i.e. the capacity of a network to maintain its integrity under removal of nodes or links. Here, we introduce network entanglement to study network robustness through a multi-scale lens, encoded by the time required to diffuse information through the system. Our measure's foundation lies upon a recently proposed framework, manifestly inspired by quantum statistical physics, where networks are interpreted as collections of entangled units and can be characterized by Gibbsian-like density matrices. We show that at the smallest temporal scales entanglement reduces to node degree, whereas at the large scale we show its ability to measure the role played by each node in network integrity. At the meso-scale, entanglement incorporates information beyond the structure, such as system's transport properties. As an application, we show that network dismantling of empirical social, biological and transportation systems unveils the existence of a optimal temporal scale driving the network to disintegration. Our results open the door for novel multi-scale analysis of network contraction process and its impact on dynamical processes.

description: In this manuscript, we study the interplay between symmetry and topology with a focus on the $Z_2$ topological index of 2D/3D topological insulators and high-order topological insulators. We show that in the presence of either a two-fold-rotational symmetry or a mirror symmetry, a gauge-invariant quantity can be defined for arbitrary 1D lines in the Brillouin zone. Such 1D quantities provide a new pathway to compute the $Z_2$ index of topological insulators. In contrast to the generic setup, where the $Z_2$ index generally involves 2D planes in the Brillouin zone with a globally-defined smooth gauge, this 1D approach only involves some 1D lines in the Brillouin zone without requiring a global gauge. Such a simplified approach can be used in any time-reversal invariant insulators with a two-fold crystalline symmetry, which can be found in 30 of the 32 point groups. In addition, this 1D quantity can be further generalized to higher-order topological insulators to compute the magnetoelectric polarization $P_3$.

It is shown that memory of early time gravitational potential is affected by presence of spatial curvature. Then we revisit Boltzmann equation for photons in the general FRW background. Using it, we show that how the frequency of oscillations and damping factor (known as Silk damping) changed in presence of spatial curvature. At last, using this modified damping factor in hydrodynamic regime of cosmological perturbations, we find our analytic solution which shows the effects of spatial curvature on growing mode of matter density.

description: Conventional conceptions of property rights focus on static definitions of property rights, usually as defined in statutory law. However, in practice there is co-existence and interaction between multiple legal orders such as state, customary, religious, project and local laws, all of which provide bases for claiming property rights. Legal anthropological approaches that recognize this legal pluralism are helpful in understanding this complexity. Individuals may choose one or another of these legal frameworks as the basis for their claims on a resource, in a process referred to as “forum shopping.” Legal pluralism can create uncertainty especially in times of conflict because any individual is unlikely to have knowledge of all types of law that might be relevant, and because rival claimants can use a large repertoire to lay claim to a resource. However, at the same time the multiple legal frameworks facilitate considerable flexibility for people to maneuver in their use of natural resources. Legal pluralism also introduces a sense of dynamism in property rights, as the different legal frameworks do not exist in isolation, but influence each other, and can change over time. Unless these aspects of property rights are recognized, changes in statutory law intended to increase tenure security may instead increase uncertainty, especially for groups with less education and contacts. This paper illustrates the implications of legal pluralism for our understanding of natural resource management and policies toward resource tenure, using the example of water rights.

description: Extending previous work in Randall-Sundrum type models, we construct low-energy effective actions for braneworlds with a bulk scalar field, with special attention to the case of BPS branes. Holding the branes at fixed coordinate position with a general ansatz for the bulk metric, and imposing the Einstein frame as a gauge condition, we obtain a scalar-tensor theory with only one scalar degree of freedom related to the proper brane separation. The formalism is applicable even when there is direct coupling of the bulk scalar and brane matter, as in the Horava-Witten model. We further show that the usual moduli space approximation actually describes a non-BPS three-brane system.

description: Social capital is a resource, a propensity for mutually beneficial collective action that communities possess to different extents. Communities with high levels of social capital are able to act together collectively for achieving diverse common objectives. While the concept of social capital is valid universally, the measure of social capital will vary by context. It must be related in each case to aspects of social relations that assist mutually beneficial collective action within that particular cultural context. A locally relevant scale of social capital was developed to assess whether and how social capital mattered for development performance in 69 north Indian villages. Variables corresponding to other bodies of explanation, including extent of commercialization, relative stratification, and relative need were also examined, but a combination of high social capital and capable agency was found to associate most closely with high development performance. Agency is important particularly in situations where institutions are not available that enable citizens to connect with the state and with markets. The productivity of social capital is considerably reduced on account of this institutional gap in the middle. Development performance can be improved in these situations by adding to the stock of social capital and also through enhancing agency capacity.

description: Arable weeds are key organisms for biodiversity maintenance and ecosystem service provision in agroecosystems. Disentangling the drivers of weed diversity is critical to counteract the global decline of farmland biodiversity. Even if distinct scale-dependent processes were alternatively proposed, no general framework unifying the multi-scale drivers of weed dynamics has yet emerged. Here, we investigate the joint effects of field- and landscape-scale processes on weed assemblages in 444 arable fields. First, field margins sheltered greater weed diversity than field core evidencing their role of biodiversity refugia. Second, community similarity between field core and margin decreased with the distance to margin, highlighting a major role of local dispersal. Third, weed diversity at field margin increased with organic field cover in the landscape, pointing out massive regional dispersal. Fourth, while both local and landscape dispersal explained up to 41% of field core weed diversity, crop type strongly modulated their strength, depicting intense filtering effect by agricultural management. This study sheds a new light on the complex multi-scale interactions shaping weed diversity, field margins playing a key role by strengthening regional dispersal and sustaining local dispersal. Land-sharing strategies improving habitat heterogeneity both locally and regionally should largely promote agroecosystem multifunctionality and sustainability.

The style of these short papers is pedagogical and the concepts in this paper are developed from fundamental manipulator robotics. This second paper considers the application of space manipulators to on-orbit servicing (OOS), an application which has considerable commercial application. I provide some background to the notion of robotic on-orbit servicing and explore how manipulator control algorithms may be modified to accommodate space manipulators which operate in the micro-gravity of space.

description: Research on collective action confronts two major obstacles. First, inconsistency in the conceptualization and operationalization of collective action, the key factors expected to affect collective action, and the outcomes of collective action hampers the accumulation of knowledge. Inconsistent terminology obscures consistent patterns. Second, the scarcity of comparable data thwarts evaluation of the relative importance of the many variables identified in the literature as likely to influence collective action. The International Forestry Resources and Institutions (IFRI) research program addresses both of these problems. Since its founding in 1993, the IFRI network of collaborating research centers has used a common set of methods and concepts to study forests, the people who use forest resources, and their institutions for resource management. The basic social unit of analysis in IFRI is the user group, defined as a set of individuals with the same rights and responsibilities to forest resources. This definition does not require formal organization or collective action, since these features are potential dependent variables. This strategy for data collection allows analysis of relationships between diverse forms of social heterogeneity and collective action within groups with comparable rights to resources. IFRIs relational database also captures the connections among forest systems, sets of resource users, particular forest products, formal and informal rules for resource use, and formal local and supralocal organizations. By the middle of 2001, the IFRI database included data on 141 sites with 231 forests, 233 user groups, 94 forest organizations, and 486 products in 12 countries. Drawing upon these data, IFRI researchers are contributing substantially to our understanding of collective action for institutional development, the mediating role institutions play relative to demographic and market pressures in patterns of resource use, and relationships between particular institutions and forest conditions. The paper describes IFRIs strategy for collecting comparable data based on consistent conceptualization and operationalization, summarizes the contributions of IFRI research to the study of collective action for natural resource management, and identifies continuing challenges.

description: Crop losses remain a persistent challenge, threatening food security, economic stability, and the well-being of rural farmers. Maize is the most grown cereal in Africa and the most important crop in Uganda. This study analyses whether farmer’s decision to switch crops every season or grow the same crops is influenced by their perception of maize crop losses. We first determine the factors that influence farmer perceptions of farm and post-harvest losses. We find that at the farm-level, storage facilities, access to information on innovations and extension service were significantly and positively associated with perception of crop losses. At post-harvest level, energy access and cost were negatively associated with perception crop losses. We also find that the perception of high crop losses on the farm is associated with the likelihood to grow same crops whereas at post-harvest level, the perception of high crop losses reduces the likelihood of growing same crop.

description: Lagrangian of the Einstein's special relativity with universal parameter $c$ ($\mathcal{SR}_c$) is invariant under Poincaré transformation which preserves Lorentz metric $η_{μν}$. The $\mathcal{SR}_c$ has been extended to be one which is invariant under de Sitter transformation that preserves so called Beltrami metric $B_{μν}$. There are two universal parameters $c$ and $R$ in this Special Relativity (denote it as $\mathcal{SR}_{cR}$). The Lagrangian-Hamiltonian formulism of $\mathcal{SR}_{cR}$ is formulated in this paper. The canonic energy, canonic momenta, and 10 Noether charges corresponding to the space-time's de Sitter symmetry are derived. The canonical quantization of the mechanics for $\mathcal{SR}_{cR}$-free particle is performed. The physics related to it is discussed.

description: A method of consensus building for management of wetlands and fisheries using a systematic approach to participatory planning and initially developed in Bangladesh is now being applied in both Bangladesh and the Mekong delta. The method recognizes diversity in livelihoods and works through a structured learning and planning process that focuses on common interests. It works with each category of stakeholder separately to prioritize the natural resource problems that their livelihoods are largely dependent on, they then share and agree common priorities in plenary. Then the stakeholder groups separately analyze possible solutions and their impacts, before meeting in plenary to share their analysis and form a consensus on win-win solutions. The process identifies the collective actions that are needed to arrive at preferred solutions, and determines potential impacts on different stakeholders and responsibilities for implementation, monitoring and evaluation. We outline the process in the context of building social capital through consensus, and compare indicators of social capital as an outcome of its application in a Vietnamese village in the Mekong delta with the outcomes of a similar process in a floodplain wetland in Bangladesh.
Diffusion of Monochromatic Classical Waves

description: We study the diffusion of monochromatic classical waves in a disordered acoustic medium by scattering theory. In order to avoid artifacts associated with mathematical point scatterers, we model the randomness by small but finite insertions. We derive expressions for the configuration-averaged energy flux, energy density, and intensity for one, two and three dimensional (1D, 2D and 3D) systems with an embedded monochromatic source using the ladder approximation to the Bethe-Salpeter equation. We study the transition from ballistic to diffusive wave propagation and obtain results for the frequency-dependence of the medium properties such as mean free path and diffusion coefficient as a function of the scattering parameters. We discover characteristic differences of the diffusion in 2D as compared to the conventional 3D case, such as an explicit dependence of the energy flux on the mean free path and quite different expressions for the effective transport velocity.

Emergence of weight-topology correlations in complex scale-free networks

description: Different weighted scale-free networks show weights-topology correlations indicated by the non linear scaling of the node strength with node connectivity. In this paper we show that networks with and without weight-topology correlations can emerge from the same simple growth dynamics of the node connectivities and of the link weights. A weighted fitness network is introduced in which both nodes and links are assigned intrinsic fitness. This model can show a local dependence of the weight-topology correlations and can undergo a phase transition to a state in which the network is dominated by few links which acquire a finite fraction of the total weight of the network.

FERTILIZER USE, RISK, AND OFF-FARM LABOR MARKETS IN THE SEMI-ARID TROPICS OF INDIA

description: The opportunity to work in the off-farm labor market allows farmers to smooth consumption in the face of a negative weather shock. This allows farmers to make production choices that have higher average returns, and greater risk. I develop a two-period dynamic programming model to explain the relationship between fertilizer demand and off-farm labor markets for a risk-averse farmer. I use a well-known sample of farmers in the semi-arid tropics of India to test the model. I show that fertilizer demand increases with the depth of the off-farm labor market. Controlling for exogenous weather risk, farmers use more fertilizer the lower the unemployment rate and the higher the share of nonagricultural work in total off-farm labor. The results have important policy implications, suggesting that labor markets and farm production are complementary in risky production environments.

description: For many years, the idea of a human with bionic muscles immediately conjures up science fiction images of a TV series superhuman character that was implanted with bionic muscles and portrayed with strength and speed far superior to any normal human. As fantastic as this idea may seem, recent developments in electroactive polymers (EAP) may one day make such bionics possible. Polymers that exhibit large displacement in response to stimulation that is other than electrical signal were known for many years. Initially, EAP received relatively little attention due to their limited actuation capability. However, in the recent years, the view of the EAP materials has changed due to the introduction of effective new materials that significantly surpassed the capability of the widely used piezoelectric polymer, PVDF. As this technology continues to evolve, novel mechanisms that are biologically inspired are expected to emerge. EAP materials can potentially provide actuation with lifelike response and more flexible configurations. While further improvements in performance and robustness are still needed, there already have been several reported successes. In recognition of the need for cooperation in this multidisciplinary field, the author initiated and organized a series of international forums that are leading to a growing number of research and development projects and to great advances in the field. In 1999, he challenged the worldwide science and engineering community of EAP experts to develop a robotic arm that is actuated by artificial muscles to win a wrestling match against a human opponent. In this paper, the field of EAP as artificial muscles will be reviewed covering the state of the art, the challenges and the vision for the progress in future years.
