description: This stocktaking workshop provided an opportunity for several groups with active interest in impact assessment relating to agricultural policy research to share experiences and views about what constitutes good practice in this field. The sponsoring organizations have had a long-standing concern for the relevance and effectiveness of agricultural and food policy research in general and at IFPRI in particular. That concern has been addressed in past meetings and the time seemed right for a further stocktaking. The focus of this 2004 meeting was on impact assessment experience at IFPRI. IFPRI has, since the mid-1990s, carried out a variety of activities aimed at assessing the impact of its policy research, capacity strengthening, and policy communications programs. The workshop brought together practitioners of such impact assessment work, users of such information, as well as researchers whose activities have been the subject of impact assessment. The cogency and necessity of such impact accounting work was reaffirmed in general terms. There was constructively critical commentary on the merits of particular approaches and instruments, such as narrative recordings and more quantitative methods of attempting to measure effects of research investments. The perennial issue of challenging counterfactuals was necessarily addressed, and the practicality of experimental and quasi-experimental methods considered. The need for consistency of assessment approaches between ex post studies (which have been the bulk of IFPRI’s experience to date) and ex ante assessment efforts that represent an increasing share of the assessment portfolio was also discussed. There has long been a commitment to work towards a strong impact-orientation “culture” within IFPRI; the workshop concluded that, while there has been progress in working toward mainstreaming such a culture, there is still far to go, and efforts must continue in this direction.

description: A relativistic coupled-channels theory for the calculation of dissociation cross sections of halo nuclei is developed. A comparison with non-relativistic models is done for the dissociation of $^{8}$B projectiles. It is shown that neglecting relativistic effects leads to seizable inaccuracies in the extraction of the astrophysical S-factor for the proton+beryllium radiative capture reaction.

Do decoupled payments really encourage farmers to work more off farm? A micro-level analysis of incentives and preferences

subject: farm operators

description: According to neo-classical theory, farm operators’ labour allocation is determined by the relative wage they can earn from their labour on and off the farm. At the equilibrium, time should be allocated so that the marginal returns from on- and off-farm work are equal. Thus, a move from coupled to decoupled payments should have important impacts on labour allocation, as it reduces the return to farm labour and increases the unearned income of operators. However, empirical studies on decoupling have shown so far only limited impact from decoupling and sometimes contradictory findings. In this paper, individual preferences and constraints are taken into account to try and identify potential barriers to labour allocation adjustment. Empirical analysis based on the intentions to adjust to decoupling of a sample of French farmers confirms a limited impact of the change in policy and calls for further investigation of the potential barriers to adjustment.

description: Human-centric explainability of AI-based Decision Support Systems (DSS) using visual input modalities is directly related to reliability and practicality of such algorithms. An otherwise accurate and robust DSS might not enjoy trust of experts in critical application areas if it is not able to provide reasonable justification of its predictions. This paper introduces Concept Localization Maps (CLMs), which is a novel approach towards explainable image classifiers employed as DSS. CLMs extend Concept Activation Vectors (CAVs) by locating significant regions corresponding to a learned concept in the latent space of a trained image classifier. They provide qualitative and quantitative assurance of a classifier's ability to learn and focus on similar concepts important for humans during image recognition. To better understand the effectiveness of the proposed method, we generated a new synthetic dataset called Simple Concept DataBase (SCDB) that includes annotations for 10 distinguishable concepts, and made it publicly available. We evaluated our proposed method on SCDB as well as a real-world dataset called CelebA. We achieved localization recall of above 80% for most relevant concepts and average recall above 60% for all concepts using SE-ResNeXt-50 on SCDB. Our results on both datasets show great promise of CLMs for easing acceptance of DSS in practice.

description: In this paper we report a new method for determining the thickness of the non-edge-on disk galaxies. Our method is based on the observation comparing with the theoretical researches of the distribution of the vertical velocity dispersion, which is obtained from the solutions of three dimensional Poisson's equation and the galactic dynamical equation. This method also allows us to investigate the mass-to-light ratio of the disk. As examples, the thickness and mass-to-light ratio of two disk galaxies, NGC 1566 and NGC 5247, which have been extensively studied in spectroscopy, have been calculated and the results are presented.

description: Advancements in mobile device computing power have made interactive web applications possible, allowing the web browser to render contents dynamically and support low-latency communication with the server. This comes at a cost to the developer, who now needs to reason more about correctness of communication patterns in their application as web applications support more complex communication patterns. Multiparty session types (MPST) provide a framework for verifying conformance of implementations to their prescribed communication protocol. Existing proposals for applying the MPST framework in application developments either neglect the event-driven nature of web applications, or lack compatibility with industry tools and practices, which discourages mainstream adoption by web developers. In this paper, we present an implementation of the MPST framework for developing interactive web applications using familiar industry tools using TypeScript and the React.js framework. The developer can use the Scribble protocol language to specify the protocol and use the Scribble toolchain to validate and obtain the local protocol for each role. The local protocol describes the interactions of the global communication protocol observed by the role. We encode the local protocol into TypeScript types, catering for server-side and client-side targets separately. We show that our encoding guarantees that only implementations which conform to the protocol can type-check. We demonstrate the effectiveness of our approach through a web-based implementation of the classic Noughts and Crosses game from an MPST formalism of the game logic.

description: With South Africa’s urban population approaching 60%, supermarkets and fast food chains have become important players in the South African food system. These large players in the food sector have systematically modified their procurement practices especially with regard to fresh fruit and vegetables and are now circumventing spot markets in favour of sourcing via in-house sourcing companies who mainly procure from preferred supplier producers. This paper draws extensively from a global research programme which seeks to highlight the market changes that potentially contribute to continued exclusion of the small producers from mass consumer markets. This paper illustrates, through a series of case studies, how integration of small-scale farmers into the urban retail market can be facilitated and how the challenges posed by the changing food system could possibly be overcome. The case studies illustrate various initiatives through which small-scale farmers and agribusinesses can be integrated into mainstream agri-food systems and may be used as models for an innovative approach to include small-scale farmers while still maintaining profitable business operations. They highlight the need for a multi actor approach for the successful participation of smallholder farmers in order to allow them to join the supply chain at any point within the channel.

description: Experimentally achieving the precision that standard quantum metrology schemes promise is always challenging. Recently, additional controls were applied to design feasible quantum metrology schemes. However, these approaches generally does not consider ease of implementation, raising technological barriers impeding its realization. In this paper, we circumvent this problem by applying closed-loop learning control to propose a practical controlled sequential scheme for quantum metrology. Purity loss of the probe state, which relates to quantum Fisher information, is measured efficiently as the fitness to guide the learning loop. We confirm its feasibility and certain superiorities over standard quantum metrology schemes by numerical analysis and proof-of-principle experiments in a nuclear magnetic resonance (NMR) system.
Tornado in the Cathedral: Decolonial Forest Imagination and the Cathedral Pines
Creators: name: Paper Buck
Publisher: name: Carnegie Mellon University
Year: 2020
Subjects: Art

description: This essay is focused on the story of an old growth forest preserve in Cornwall, Connecticut known as the Cathedral Pines. The author, who grew up beside the forest, looks at the lifecycle of the forest as a case study in settler constructions of forests, conservation, and the American landscape. The author uses archival research and outreach to local indigenous and environmental activists to explore the social and ecological processes that have shaped the Cathedral Pines, within broader regional histories. The text looks at the political economic history and symbolism attached to white pine trees to explore the impacts of racial colonialism on the present ecology of forests within the Housatonic and Hudson River valley regions. The author argues that settler mythologies of wilderness continue to structure discourses of conservation. The concluding sections of the text draw on decolonial discourses of “reciprocity” to think about the potentialities embedded in efforts to align forest restoration efforts with indigenous-led environmental justice movements.

description: Magnetic activity of the Sun and other stars causes their brightness to vary. We investigate how typical the Sun's variability is compared to other solar-like stars, i.e. those with near-solar effective temperatures and rotation periods. By combining four years of photometric observations from the Kepler space telescope with astrometric data from the Gaia spacecraft, we measure photometric variabilities of 369 solar-like stars. Most of the solar-like stars with well-determined rotation periods show higher variability than the Sun and are therefore considerably more active. These stars appear nearly identical to the Sun, except for their higher variability. Their existence raises the question of whether the Sun can also experience epochs of such high variability.

description: Most of the climate change models for South Africa predict a reduction in freshwater availability by 2050. Population growth is projected at 3% per annum, implying increased domestic water use. In addition to these factors, the concern for ecological sustainability and increased water pollution due to increased industrial, mining and agricultural activities, water availability for sectoral production activities is expected to decline. This decline has an impact on sectoral output, value added and households’ welfare. Using a computable general equilibrium approach, this study investigates the possible impact of global change on households’ welfare. The simulation results show that water scarcity due to global change can potentially lead to a general deterioration in households’ welfare. The poor households, whose incomes are adversely impacted, are the most vulnerable to the consequences of the impact of global change on water resources in South Africa. This vulnerability can only be reduced if welfare policies that maintain food consumption levels for the least and low-income households are implemented.
States and Boundary Terms: Subtleties of Lorentzian AdS/CFT

description: We complete the project of specifying the Lorentzian AdS/CFT correspondence and its approximation by bulk semi-classical methods begun by earlier authors. At the end, the Lorentzian treatment is self-contained and requires no analytic continuation from the Euclidean. The new features involve a careful study of boundary terms associated with an initial time $t_-$ and a final time $t_+$. These boundary terms are determined by a choice of quantum states. The main results in the semi-classical approximation are 1) The times $t_\pm$ may be finite, and need only label Cauchy surfaces respectively to the past and future of the points at which one wishes to obtain CFT correlators. Subject to this condition on $t_\pm$, we provide a bulk computation of CFT correlators that is manifestly independent of $t_\pm$. 2) As a result of (1), all CFT correlators can be expressed in terms of a path integral over regions of spacetime {\it outside} of any black hole horizons. 3) The details of the boundary terms at $t_\pm$ serve to guarrantee that, at leading order in this approximation, any CFT one-point function is given by a simple boundary value of the classical bulk solution at null infinity, $I$. This work is dedicated to the memory of Bryce S. DeWitt. The remarks in this paper largely study the relation of the AdS/CFT dictionary to the Schwinger variational principle, which the author first learned from DeWitt as a Ph.D. student.

description: The production of biofuels from agricultural commodities has received much attention in recent years. Apart from a few private initiatives, biofuels have not seen a large scale, commercial production in South Africa to date. This article sketches a basic picture of the economic feasibility of biofuel production in South Africa, without any form of government support, at 2006 prices. It then takes the analysis a step further and with the aid of a set of scenarios, different potential outcomes, due to a range of possible policy implementation measures, are discussed and the results documented. The Bureau for Food and Agricultural Policy’s (BFAP) sector model is used to simulate the impact of various options on the potential biofuels industry and other related industries during the course of the 2007 to 2015 period. This study shows that a lack of government support for the local biofuels industry could seriously affect its economic viability, especially in the early stages of the industry’s development. Additional issues, such as the impact on food and feed prices, also need to be taken into consideration.

The new Einstein-Sasaki spaces L^{p,q,r} in five dimensions have cohomogeneity 2, and U(1) x U(1) x U(1) isometry group. They are topologically S^2 x S^3. Their AdS/CFT duals will describe quiver theories on the four-dimensional boundary of AdS_5. We also obtain new Einstein-Sasaki spaces of cohomogeneity n in all odd dimensions D=2n+1 \ge 5, with U(1)^{n+1} isometry.

description: This article presents a deterministic farm-level model developed to link to an existing partial equilibrium sector-level model of the grain and livestock sectors of South Africa. The objective is to create a linked system of models consisting of a sector- and farm-level model with the capability to analyse the likely effects of changes in policies and markets at both the sector and representative farm level in South Africa. A representative farm in the Free State Province is used to validate the farm-level model. The farm-level model is used to simulate a baseline as well as two scenarios of the representative farm for the period 2003 to 2010. Results indicate that the farm-level model simulates the representative farm rather accurately compared to historical data. The baseline and scenario results indicate that the linked system of models can be useful for policy and business decision-makers to analyse the impact of change in policies and markets at both the sector- and farm level.

description: While many studies have identified infrastructure as a constraints to production in agriculture in South Africa, few have attempted to investigate the extent to which emerging farmers are able to access and utilise infrastructure services. This paper uses data collected from 500 emerging farmers across the nine provinces of South Africa to determine the accessibility and use of infrastructure by emerging farmers. Factor Analysis was applied on fifteen indicators of infrastructure. The principal components extraction method extracted four factors, namely distance to services infrastructure, tarred road conditions to the services infrastructure, visitation to general services infrastructure and agricultural support services infrastructure. The results show that services infrastructure is generally more accessible to emerging farmers than before. The factors that determine the accessibility to infrastructure services include the distance of the nearest town from the villages, the state of the roads that farmers use and the frequency of visits to the nearest town. The distance to services infrastructure is segregated from condition and usage. The results indicate that all services are in a more or less similar location and in similar condition in terms of access. The implication of this study is that policy should address farmers’ access to services, which are sometimes in bundles, and the role of locating services in centres is pertinent as it stimulates agricultural and rural development.

description: In this new century, organizational learning assumes a great relevance. It was sought by means of that research work to explore the literature and to present some theoretical reflections about learning process in adults as an attempt of better understanding the paradigms of analysis turned to the process of learning in organizations. The theoretical construct of this investigation is centered on the theory of the transformative learning of adults developed by Merizow (1991, 1997). This work has as the central goal to investigate, under the optics of the theory, the andragogical proposal of Petrobras. More specifically, it was intended in this investigation : i) redeem some aspects of history of this organization, distinguishing the elements that structured the andragogical process proposed by its corporative university and; ii) verify whether the andragogical proposition of the organization object of analysis, guides itself by the pre-supposed of transformative learning theory. Research concluded that a number of presuppositions of the theory are present in the andragogical proposal of the corporative university of the organization studied. However, there is a diversity of important presuppositions defended by the theory, which are not yet placed into practice in corporative education of that organization. This investigation finalizes with the proposition that other studies be performed encompassing that important thematic, aiming to present new proposals of educative programs for the corporative university and enterprises in general.

description: We investigate the quintessence scalar field model modified by the Generalized Uncertainty Principle in the background of a spatially flat homogeneous and isotropic universe. By performing a dynamical system analysis we examine the nature of the critical points and their stability for two potentials, one is the exponential potential and the other is a general potential. In the case of an exponential potential, we find some new critical points for this modified quintessence scenario that describe the de Sitter universe, and these critical points do not appear in the standard quintessence model with an exponential potential. This is one of the main results of this work. Now for the general potential our analysis shows that the physical properties of the critical points remain exactly the same as for the exponential potential which means that within this modified quintessence scenario all kind of potentials have same behaviour. This kind of result is completely new in cosmology because with the change of the potential, differences are usually expected in all respect.

description: Although ECR has been one of most important subjects discussed by the grocery industry and a relevant topic mentioned by the academics, it is notable the difficulty to understand its implementation and operation. Based on these facts, this study aimed to discuss the concept of ECR by critically analyzing its implementation and bring some knowledge about this theme. The paper argues that while there is some evidence to suggest that ECR is an important tool, there is a need to more clearly explain how the ECR can really improve the operations between companies. The ECR literature is discussed, by following an empirical research conducted with industries, wholesalers and retailers of the grocery industry channel in Brazil. This research attempts to identify which strategies, processes and technologies of ECR have been applied by participating companies, the reasons for firms adopting the ECR, the difficulties confronted during the implementation process and how these firms felt about the diffusion of ECR strategies in Brazil. The study provides useful insights about the impact of the ECR initiative on firms that would like to maximize ECR implementation or begin the adoption of this practice.

description: We study the ^{1}S_{0} proton pairing gap in neutron star matter putting emphasis on influence of the Dirac effective mass and the proton fraction on the gap within the relativistic Hartree-Bogoliubov model. The gap equation is solved using the Bonn-B potential as a particle-particle channel interaction. It is found that the maximal pairing gap Δ_{max} is 1-2 MeV, which has a strong correlation with the Dirac effective mass. Hence we suggest that it serves as a guide to narrow down parameter sets of the relativistic effective field theory. Furthermore, the more slowly protons increase with density in the core region of neutron stars, the wider the superfluid range and the slightly lower the peak of the gap become.

Stochastic chemical enrichment in metal-poor systems II. Abundance ratios and scatter
Creators: name: Karlsson, T.
name: Gustafsson, B.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A stochastic model of the chemical enrichment of metal-poor systems by core-collapse supernovae is used to study the scatter in stellar abundance ratios. The resulting scatter in abundance ratios, e.g. as functions of the overall metallicity, is demonstrated to be crucially dependent on the as yet uncertain supernovae yields. The observed abundance ratios and their scatters therefore have diagnostic power as regards the yields. The relatively small star-to-star scatter observed in many chemical abundance ratios, e.g. by Cayrel et al. (2004) for stars down to [Fe/H] = -4, is tentatively explained by the averaging of a large number of contributing supernovae and by the cosmic selection effects favoring contributions from supernovae in a certain mass range for the most metal-poor stars. The scatter in observed abundances of alpha-elements is understood in terms of observational errors only, while additional spread in yields or sites of nucleosynthesis may affect the odd-even elements Na and Al. For the iron-group elements we find systematically too high predicted Cr/Fe and Cr/Mg ratios, as well as differences between the different sets of yields, both in terms of predicted abundance ratios and scatter. The semi-empirical yields recently suggested by Francois et al. (2004) are found to lead to scatter in abundance ratios significantly greater than observed, when applied in the inhomogeneous models. "Spurs", very narrow sequences in abundance-ratio diagrams, may disclose a single-supernova origin of the elements of the stars on the sequence. Verification of the existence of such features, called single supernova sequences (SSSs), is challenging. This will require samples of several hundred stars with abundance ratios observed to accuracies of 0.05 dex or better.

description: Designing proper time-dependent control fields for slowly varying the system to the ground state that encodes the problem solution is crucial for adiabatic quantum computation. However, inevitable perturbations in real applications demand us to accelerate the evolution so that the adiabatic errors can be prevented from accumulation. Here, by treating this trade-off task as a multiobjective optimization problem, we propose a gradient-free learning algorithm with pulse smoothing technique to search optimal adiabatic quantum pathways and apply it to the Landau-Zener Hamiltonian and Grover search Hamiltonian. Numerical comparisons with a linear schedule, local adiabatic theorem induced schedule, and gradient-based algorithm searched schedule reveal that the proposed method can achieve significant performance improvements in terms of the adiabatic time and the instantaneous ground-state population maintenance. The proposed method can be used to solve more complex and real adiabatic quantum computation problems.

description: This paper has sought to evaluate the economical efficiency in the use of productive resources in the coffee production in the south region of the state of Minas Gerais. Economical efficiency was estimated through a production frontier function using a sample of 43 coffee producers. The average economical efficiency index reached by the coffee producers in the south of Minas Gerais was 80,14%. Such index indicates that a tendency to gains in productions can be obtained through a better allocation of the production factors, which may lead them to operate on the production frontier line.

Canada’s location in the world system : reworking the debate in Canadian political economy
Creators: name: Burgess, William
Publisher: name: University of British Columbia
Year: 2009

description: Canada is more accurately described as an independent imperialist country than a relatively dependent or foreign-dominated country. This conclusion is reached by examining recent empirical evidence on the extent of inward and outward foreign investment, ownership links between large financial corporations and large industrial corporations, and the size and composition of manufacturing production and trade. In each of these areas, the differences between Canada and other members of the G7 group of countries are not large enough to justify placing Canada in a different political-economic status than these core imperialist countries. An historical context for the debate over Canada's current status is provided by archival research on how socialists in the 1920s addressed similar issues. Imperialist status means that social and economic problems in Canada are more rooted in Canadian capitalism and less in foreign capitalism than is generally assumed by left-nationalist Canadian political economy. Given Canada's imperialist status, labour and social movements in Canada should not support Canadian nationalism, e.g., oppose 'free' trade and globalization on this basis.
Is there a relationship between the mass of a SMBH and the kinetic energy of its host elliptical galaxy?

description: We use a restricted sample of elliptical galaxies, whose kinematical parameters inside the semimajor axis were calculated correcting the effect of the integration of the light along the line of sight, in order to analyze a possible relationship between the mass of a Supermassive Black Hole (SMBH) and the kinetic energy of random motions in the host galaxy. We find $M_{BH} \propto (M_{G} σ^{2})^α$ with $0.87 \leq α\leq 1$ depending on the different fitting methods and samples used. This result could be interpreted as a new fundamental relationship or as a new way to explain the old $M_{BH} - σ$ law. In fact, the relations of the velocity dispersion both with the mass of the SMBH ($M_{BH} \propto σ^{4.12}$) and with the mass of the host galaxy ($M_{G} \propto σ^{2.16}$) induce us to infer an almost direct proportionality: $M_{BH} \propto M_{G} σ^{2}$. A similar relationship is found for the total kinetic energy involving the rotation velocity too.

Bounded verification of message-passing concurrency in Go using Promela and Spin

description: This paper describes a static verification framework for the message-passing fragment of the Go programming language. Our framework extracts models that over-approximate the message-passing behaviour of a program. These models, or behavioural types, are encoded in Promela, hence can be efficiently verified with Spin. We improve on previous works by verifying programs that include communication-related parameters that are unknown at compile-time, i.e., programs that spawn a parameterised number of threads or that create channels with a parameterised capacity. These programs are checked via a bounded verification approach with bounds provided by the user.

Agricultural Finance

description: Financial stress in agricultural cooperatives may be due to a combination of three factors: inadequate profitability, excessive debt, or high interest rates. This paper uses an analytical technique to determine the relative degree of financial stress in agricultural cooperatives attributable to each factor. Roughly 30 percent of agricultural cooperatives in our sample suffered financial stress from 1987 through 1992. The analysis indicates that the greatest portion of financial stress, 54 percent, originated from low earnings. High interest rates accounted for roughly 24 percent of the financial stress while leverage accounts for the remaining 22 percent. The results also indicate that smaller cooperatives are more than twice as likely to face financial stress than larger cooperatives. Small cooperatives are more likely to face profitability problems whereas large cooperatives are more likely to face debt and interest rate problems.
A Body Between

description: Virtual space is liminal and offers experiences that reflect on embodied experience. Oscillating between realities of the physical and virtual realms reveals a hybridized bodythat is both digital and flesh. A new somatic knowledge is gained from physicalized experience of digital space and a digital experience of the physical. The following discussion is about two bodies of Michael Charles Neumann’s exploratory work, Field of Bodies (2018) and Shadow and Dust (2018).Neumann’s work creates opportunities in experiential forms of art for hybridized bodies and subjectivities by creating prostheses, sculpting bodies in virtual worlds, anddesigning processes that focus attention on the physicality, features, flexibility and failures of the body. His work reveals the experience of being held in suspension betweenphysical and virtual worlds, revealing an alternate embodied experience. The thesis is structured as follows. A brief background contextualizes Neumann's work within a historical lineage of media artists who employ technology as a self-reflexive medium and content. Five case studies evaluate Neumann’s virtual works with the criteria of: rationale, planning and execution, key aesthetics, and critical appraisal. Discussion of the rationale unpacks questions and inclinations that give direction to the works. Planning and execution will consider how questions ofembodiment become the process of working, and how each of the works is completed. Key aesthetics describes the main features of the works and their formal qualities in form,performance, and presentation strategies. Lastly, critical appraisal analyzes each of the five works and evaluates presentation and embodied experience. This essay concludes by assessing the exploration of this work, how it achieves an alternate embodied experience, and suggests avenues for inquiry in future research.

description: We investigate the metal enrichment of elliptical galaxies in the framework of hierarchical models of galaxy formation. The semi-analytical model we use in this Letter, which has been used to study the metal enrichment of the intracluster medium (ICM) by Nagashima et al., includes the effects of flows of gas and metals both into and out of galaxies and the processes of metal enrichment due to both type Ia and type II supernovae. We adopt a solar neighbourhood IMF for star formation in discs, but consider models in which starbursts have either a solar neighbourhood IMF or a top-heavy IMF. We find that the alpha-element abundance in ellipticals is consistent with observed values only if the top-heavy IMF is used. This result is consistent with our previous study on the metal enrichment of the ICM. We also discuss the abundance ratio of alpha elements to iron as a function of velocity dispersion and metallicity. We find that models with a top-heavy IMF match the alpha/Fe ratios observed in typical L_* ellipticals, but none of the models reproduce the observed increase of alpha/Fe with velocity dispersion.
