description: Devido às suas dimensões continentais e às condições ambientais dos trópicos (temperatura e umidade elevadas), o Brasil tem alta biodiversidade e grande potencial de produção de biomassa. A biodiversidade oferece uma grande variedade de produtos que podem ser explorados, tais como a biomassa vegetal, que pode ser utilizada como madeira para móveis e construção civil, fabricação de celulose (papel), lenha, carvão, combustível além de servir de matéria-prima para artesanato. Apesar disso, esse potencial produtivo é subutilizado no Brasil. O setor florestal brasileiro não aproveita sua biodiversidade, utilizando apenas monoculturas de espécies exóticas. Sua produção madeireira é pequena, considerando que se trata do país com a 2ª maior extensão de florestas do mundo. Este trabalho analisa a viabilidade da produção de biomassa vegetal (com enfoque especial para a madeira) na caatinga brasileira, bioma erroneamente considerado como pobre em biodiversidade e de baixa produtividade primária. O potencial de produção madeireira poderia ser aproveitado através de um plano de manejo adequado, com rotatividade de parcelas e gerenciamento integrada da biodiversidade.-----------------------------------------------Due to its continental dimensions and the tropical environmental conditions (high temperature and humidity), Brazil has high biodiversity and great potential of biomass production. The biodiversity offers a great variety of products that can be explored, such as the vegetal biomass, which can be used as wood for furniture and building construction, making cellulose for paper mill, firewood, coal, biofuel, besides serving as raw material for workmanship. The Brazilian forest sector does not take advantage of its biodiversity, only making use of the exotic species in monocultures. The Brazilian lumber production is low, considering that it is the country with the second largest forest area in the world. This paper analyzes the feasibility of the vegetal biomass production (with special emphasis to the wood) in the Brazilian caatinga, bioma mistakenly considered as poor in biodiversity and low primary productivity. The potential of lumber production could be taken advantage of an adequate management plan, with rotation of parcels and integrated management of the biodiversity.

description: O pequi (Caryocar brasiliense Camb.) é um fruto nativo com ocorrência generalizada no Bioma Cerrado. O consumo e comercialização do fruto "in natura" e de seus derivados, com importância sócio-econômica, geram renda e emprego para agricultores familiares e trabalhadores com pouca qualificação profissional. Entretanto, a exploração sustentável desta atividade encontra-se ameaçada pelo desconhecimento do mercado consumidor, inexistência de padrões de qualidade na comercialização, dispersão, desarticulação e informalidade dos agentes e segmentos do arranjo extrativista. Visando gerar informações que contribuam para o fortalecimento da cadeia extrativista e o desenvolvimento sustentável, este trabalho teve como objetivos identificar e caracterizar os agentes consumidores de pequi no principal centro consumidor: Goiânia. Constatou-se que, em Goiânia, existe mercado de consumo empresarial, formado por restaurantes além dos consumidores finais que adquirem o produto em feiras e de ambulantes. ---------------------------------------------The “pequi” (Caryocar brasiliense Camb.) is a traditional fruit in the culture of the inhabitants of the Brazilian Savanna which is still harvested from wild trees. The sustainable use of this species is at the moment threatened by limitations such as: the lack of knowledge of type of products commercialized, and dispersion and disarticulation of the main agents members of the chain of the fruit collectors; besides the general informality in component agents. On the other hand its use vitalizes the economy of several counties in Goiás, capable of contributing to a sustainable territorial development from a social and environmental point of view. At present, the consume and commercialization of the fruit “in natura” and its derivates (preserves, oil, liqueur, soap, etc) have great socio-economic significance: it is used in various typical dishes and is a symbol of the local gastronomy, besides complementing the diet of the agricultural population and generating income and jobs to a sizeable parcel of family farmers. This study has as its main goal the discussion about the consumer market of the fruits and derivates in Goiânia, state of Goiás.

description: In planar QCD, in two space time dimensions, the meson eigenvalue equation has a nonlocal structure interpretable as resulting from hidden degrees of freedom. The nonlocality can be reconstructed from the functional form of the pion mass dependence on quark mass within an expansion starting from a special one dimensional Schroedinger problem. The one dimensional problem makes the pion mass depend on the quark mass through a simple quadratic relation which is shown to be compatible also with numerical data obtained in four dimensions.

description: We write a gravity theory with Yang-Mills type action using the biconformal gauging of the conformal group. We show that the resulting biconformal Yang-Mills gravity theories describe 4-dim, scale-invariant general relativity in the case of slowly changing fields. In addition, we systematically extend arbitrary 4-dim Yang-Mills theories to biconformal space, providing a new arena for studying flat space Yang-Mills theories. By applying the biconformal extension to a 4-dim pure Yang-Mills theory with conformal symmetry, we establish a 1-1, onto mapping between a set of gravitational gauge theories and 4-dim, flat space gauge theories.

description: Motivated by recent progress on synthesizing two-dimensional magnetic van der Waals systems, we propose a setup for detecting the topological Berezinskii-Kosterlitz-Thouless (BKT) phase transition in spin-transport experiments on such structures. We demonstrate that the spatial correlations of injected spin-currents into a pair of metallic leads can be used to measure the predicted universal jump of $2/π$ in the ferromagnet spin-stiffness as well as its predicted universal square root dependence on temperature as the transition is approached from below. Our setup provides a simple route to measuring this topological phase transition in two-dimensional magnetic systems, something which up to now has proven elusive. It is hoped that this will encourage experimental efforts to investigate critical phenomena beyond the standard Ginzburg-Landau paradigm in low-dimensional magnetic systems with no local order parameter.

description: We point out the existence of a consistency relation involving the 3-point function of scalar perturbations which is valid in any inflationary model, independently of the inflaton Lagrangian under the assumption that the inflaton is the only dynamical field. The 3-point function in the limit in which one of the momenta is much smaller than the other two is fixed in terms of the power spectrum and its tilt. This relation, although very hard to verify experimentally, could be easily proved wrong by forecoming data, thus ruling out any scenario with a single dynamical field in a model independent way.

ATMO-ACCESS D6.1 General Design Concept for flexible access modalities
Creators: name: Wenger, John
Publisher: name: UCC
Year: 2022

description: The concept of physical access to a single facility in a specific Research infrastructure (RI) has typically been the norm for transnational access (TNA) activities over the last decade. However, new and flexible approaches for providing access are required to allow RIs to deliver improved services that attract a wider range of users and stakeholders. WP6 addresses this need by designing and evaluating new mechanisms for accessing research facilities in the atmospheric domain of European RIs. In addition to physical access (in-person visit to a facility), both remote access (without a person visiting a facility) and virtual access (wide, free access provided through communication networks to resources and data that can be simultaneously used by an unlimited number of users) will be explored. These new access modalities and improved services will provide better support to users, allowing them to address key scientific questions and the related societal issues in a new way. WP6 will therefore provide additional options to the catalogue of services offered by the participating RIs and enhance their attractiveness with cross-RI services and opportunities not offered by single RIs. The enhanced access modalities will also facilitate cross-disciplinary research and technology development, while also fostering closer interactions between academics and industry.
Impact of an introduced population of Eulemur fulvus on a native population of Lemur catta at Berenty Reserve, Madagascar
Creators: name: Pinkus, Susan Elizabeth
Publisher: name: University of British Columbia
Year: 2012

description: One of the largest protected populations of the Ringtail lemur (Lemur catta) lives in Berenty Reserve, a 400ha riverine forest in semi-arid southeastern Madagascar. Nine Brown lemurs (Eulemur fulvus) were introduced into Berenty in 1974. When these two species exist in natural sympatry, they overlap little in diet or habitat use. Brown lemurs specialize on closed-canopy forest but Ringtails are semi-terrestrial and use both forest and adjacent scrub habitat. In contrast, preliminary data at Berenty indicated broad interspecific overlap. I tested the hypothesis that the increasing Brown lemur population is having a negative demographic impact on Ringtails at Berenty. I also sought to understand what factors affect Ringtail and Brown lemur population density there. I studied the resource use, population dynamics, and response to drought, of Ringtails and Brown lemurs at Berenty. I compared the diet and habitat use of seven troop-pairs each with one Ringtail and one Brown lemur troop living in overlapping home ranges, and thus sharing access to the same resources. I found that paired Ringtail and Brown lemur troops living in the same habitat type overlapped more in diet than did adjacent troops of the same species. Census data showed that between 1974 and 2000, the numbers of both species increased, and the combined density of the two populations quadrupled. Ringtail numbers have been stable since 1995, while Brown lemur numbers continue to grow. However, juvenile recruitment in Ringtails declined with increasing Brown lemur density in scrub habitat. Juvenile recruitment in Ringtails, but not in Brown lemurs, also declined following droughts. This is likely the result of reduced productivity in the keystone food tree species Tamarindus indica after droughts. Despite the high overlap in diet of Brown lemurs and Ringtails at Berenty, I found no evidence that the socially dominant Brown lemur is lowering the demographic performance of the Ringtail. I suggest that water provisioning at Berenty explains this apparent paradox.

description: This note shows that the assumptions about the abatement technology modify the impact of the environmental taxation (both the size and the “direction”) on the long-run growth driven by human capital accumulation à la Lucas (1988), when the source of pollution is private consumption and lifetime is finite. When the human capital’s share in the abatement services production is higher (respectively lower) than in the final output production, a higher environmental tax reduces (resp. increases) the allocation of human capital in production sectors (abatement service and final output) and boostes (resp. decreases) the BGP rate of growth. When abatement services are produced with the final output, the environmental taxation does not influence growth.

description: In many low-income countries, agriculture is mostly rain-fed and yields highly depend on climatic factors. Furthermore, farmers have little access to traditional crop insurance, which suffers from high information asymmetry and transaction costs. Insurances based on meteorological indices could fill this gap since they do not face such drawbacks. However their implementation has been slow so far. In this article, we first describe the most advanced projects that have taken place in developing countries using these types of crop insurances. We then describe the methodology that has been used to design such projects, in order to choose the meteorological index, the indemnity schedule and the insurance premium. We finally draw an agenda for research in economics on this topic. In particular, more research is needed on implementation issues, on the assessment of benefits, on the way to deal with climate change, on the spatial variability of weather and on the interactions with other hedging methods.

description: Global Navigation Satellite Systems (GNSS) brought navigation to the masses. Coupled with smartphones, the blue dot in the palm of our hands has forever changed the way we interact with the world. Looking forward, cyber-physical systems such as self-driving cars and aerial mobility are pushing the limits of what localization technologies including GNSS can provide. This autonomous revolution requires a solution that supports safety-critical operation, centimeter positioning, and cyber-security for millions of users. To meet these demands, we propose a navigation service from Low Earth Orbiting (LEO) satellites which deliver precision in-part through faster motion, higher power signals for added robustness to interference, constellation autonomous integrity monitoring for integrity, and encryption / authentication for resistance to spoofing attacks. This paradigm is enabled by the 'New Space' movement, where highly capable satellites and components are now built on assembly lines and launch costs have decreased by more than tenfold. Such a ubiquitous positioning service enables a consistent and secure standard where trustworthy information can be validated and shared, extending the electronic horizon from sensor line of sight to an entire city. This enables the situational awareness needed for true safe operation to support autonomy at scale.

The SRO/Nb:STO interface exhibits rectifying current-voltage ($I$-$V$) characteristics agreeing with those of a Schottky junction composed of a deep work-function metal (SRO) and an $n$-type semiconductor (Nb:STO). A hysteresis appears in the $I$-$V$ characteristics, where high resistance and low resistance states are induced by reverse and forward bias stresses, respectively. The resistance switching is also triggered by applying short voltage pulses of 1 $μ$s - 10 ms duration.

description: Personalizing medical devices such as lower limb wearable robots is challenging. While the initial feasibility of automating the process of knee prosthesis control parameter tuning has been demonstrated in a principled way, the next critical issue is to improve tuning efficiency and speed it up for the human user, in clinic settings, while maintaining human safety. We, therefore, propose a policy iteration with constraint embedded (PICE) method as an innovative solution to the problem under the framework of reinforcement learning. Central to PICE is the use of a projected Bellman equation with a constraint of assuring positive semidefiniteness of performance values during policy evaluation. Additionally, we developed both online and offline PICE implementations that provide additional flexibility for the designer to fully utilize measurement data, either from on-policy or off-policy, to further improve PICE tuning efficiency. Our human subject testing showed that the PICE provided effective policies with significantly reduced tuning time. For the first time, we also experimentally evaluated and demonstrated the robustness of the deployed policies by applying them to different tasks and users. Putting it together, our new way of problem solving has been effective as PICE has demonstrated its potential toward truly automating the process of control parameter tuning for robotic knee prosthesis users.

description: Longitudinal optical phonons with oxygen character were measured in La_0.7Sr_0.3MnO_3 by inelastic neutron scattering in the (1 0 0) cubic direction and results were compared with shell model predictions. Measurements were performed in several Brillouin zones, which enabled us to identify the eigenvectors independent of the shell model. All major disagreements between model predictions and experimental results are primarily due to the anomalous downward dispersion of the bond-stretching vibration. The main new result is that the rhombohedral distortion of the cubic lattice makes the bond-stretching vibrations interact strongly with bond-bending modes folded into the cubic Brillouin zone.

description: With complementary Chinese data sets and alternative corruption measures, we explore the consequences of corruption. Adopting a novel approach we provide evidence that corruption can have both, positive and negative effects, on economic development. The overall impact of corruption might be the balance of the two simultaneous effects within a specific institutional environment (“grease the wheels” and “sand the wheels”). Corruption is observed to considerably increase income inequality in China. We also find that corruption strongly reduces tax revenue. Looking at things from an expenditure point of view we observe that corruption significantly decreases government spending on education, R&D and public health in China. We also observe that regional corruption significantly reduces inbound foreign direct investment in Chinese regions, which indicates that the pollution haven hypothesis may not hold in China. This finding sheds a new light on the “China puzzle” that China is the largest developing host of FDI while it is appears to be very corrupt. Finally we observe that corruption substantially aggravates pollution probably through loosening environment regulation, and that it modifies the effects of trade openness and FDI on the stringency of environmental policy in a manner opposite to that observed in literature to date.

description: In order to activate the cycle of wealth production, promote social justice and eliminate poverty and inequality, developing countries are currently faced with a multiplicity of structural problems. According to some economic theories, this is mainly due to inefficient or lack of access to financial resources, which has proved a major obstacle in activating the cycle of wealth production in such countries. On this assumption, countries with huge oil reserves including Iran, should not encounter obstacles in terms of creating and accelerating the national cycle of wealth production. However, the fact is almost all major oil-producing countries and the main exporters of petroleum products in the world are dealing with serious structural issues in establishing a natural cycle of wealth production and a cycle of wealth and income distribution. In order to examine the dependence of Iran’s economic systems (as one of the major exporters of petroleum products) on oil revenues, the paper shall first present an overview of the energy sector in these countries by expounding on their conditions and features and redefine the issue. Thus, in addition to an overview of Iran’s unique geographical and demographic features and a brief account of its history of oil discovery and its effects on the country’s continuum of social and historical events, the paper is going to elaborate on its oil and gas reserves and resources. In the end, considering the huge effect of petroleum export on Iran’s annual budget and its economy and the country’s necessities and obligations, the paper explains some strategies for reducing the economy’s dependence on oil and gas resources in the future and the main obstacles to implementation of these strategies.
Probing the magnetospheres of chemically peculiar stars through the dips in their light curves
Creators: name: Mikulášek, Zdeněk
Publisher: name: Zenodo
Year: 2024

description: The advent of extensive photometric surveys such as Kepler, Corot, TESS, or BRITE missions has enabled the recent unexpected unveiling of short-term dips in the phase light curves of some magnetic chemically peculiar stars of the upper main sequence, such as HD 37776. We speculate that this novel type of stellar variability is caused by repeating transits of semi-transparent structures of stellar plasma trapped in the corotating magnetospheres of stars with a strong magnetic field. In the light curves of such stars, we typically observe several dips with a typical depth from fractions of mmag to several mmag, the configuration of which is persistent in the scale of decades. The occurrence of photometric dips, frequency, and prominence in the light curves of rotationally modulated objects allows us to judge magnetospheres' dimension and strength, making this analysis a universally available instrument for diagnosing stellar magnetic fields. Dip analysis will be demonstrated using examples of notorious mCP stars such as 56 Ari and EE Dra.

description: Background: Out-of-plane lesions pose challenges for CT-guided interventions. Augmented reality (AR) headset devices have evolved and are readily capable to provide virtual 3D guidance to improve CT-guided targeting. Purpose: To describe the design of a three-dimensional (3D) AR-assisted navigation system using HoloLens 2 and evaluate its performance through CT-guided simulations. Materials and Methods: A prospective trial was performed assessing CT-guided needle targeting on an abdominal phantom with and without AR guidance. A total of 8 operators with varying clinical experience were enrolled and performed a total of 86 needle passes. Procedure efficiency, radiation dose, and complication rates were compared with and without AR guidance. Vector analysis of the first needle pass was also performed. Results: Average total number of needle passes to reach the target reduced from 7.4 passes without AR to 3.4 passes with AR (54.2% decrease, p=0.011). Average dose-length product (DLP) decreased from 538 mGy-cm without AR to 318 mGy-cm with AR (41.0% decrease, p=0.009). Complication rate of hitting a non-targeted lesion decreased from 11.9% without AR (7/59 needle passes) to 0% with AR (0/27 needle passes). First needle passes were more nearly aligned with the ideal target trajectory with AR versus without AR (4.6° vs 8.0° offset, respectively, p=0.018). Medical students, residents, and attendings all performed at the same level with AR guidance. Conclusions: 3D AR guidance can provide significant improvements in procedural efficiency and radiation dose savings for targeting challenging, out-of-plane lesions. AR guidance elevated the performance of all operators to the same level irrespective of prior clinical experience.

description: This research examines the economic origins of Islam and uncovers two empirical regularities. First, Muslim countries, virtual countries and ethnic groups, exhibit highly unequal regional agricultural endowments. Second, Muslim adherence is systematically larger along the pre-Islamic trade routes in the Old World. The theory argues that this particular type of geography (i) determined the economic aspects of the religious doctrine upon which Islam was formed, and (ii) shaped its subsequent economic performance. It suggests that the unequal distribution of land endowments conferred differential gains from trade across regions, fostering predatory behavior from the poorly endowed ones. In such an environment it was mutually beneficial to institute a system of income redistribution. However, a higher propensity to save by the rich would exacerbate wealth inequality rendering redistribution unsustainable, leading to the demise of the Islamic unity. Consequently, income inequality had to remain within limits for Islam to persist. This was instituted via restrictions on physical capital accumulation. Such rules rendered the investments on public goods, through religious endowments, increasingly attractive. As a result, capital accumulation remained low and wealth inequality bounded. Geography and trade shaped the set of economically relevant religious principles of Islam affecting its economic trajectory in the preindustrial world.

description: Information-theoretic arguments are used to obtain a link between the accurate linearity of Schrodinger's equation and Lorentz invariance: A possible violation of the latter at short distances would imply the appearance of nonlinear corrections to quantum theory. Nonlinear corrections can also appear in a Lorentz invariant theory in the form of higher derivative terms that are determined by a length scale, possibly the Planck length. It is suggested that the best place to look for evidence of such quantum nonlinear effects is in neutrino physics and cosmology.

description: China, from its own perspective cannot afford to, and from an international perspective, is not allowed to continue on the conventional path of encouraging economic growth at the expense of the environment. The country needs to transform its economy to effectively address concern about a range of environmental problems from burning fossil fuels and steeply rising oil import and international pressure to exhibit greater ambition in fighting global climate change. This paper first discusses China’s own efforts towards energy saving and pollutants cutting, the widespread use of renewable energy and participation in clean development mechanism, and puts carbon reductions of China’s unilateral actions into perspective. Given that transition to a low carbon economy cannot take place overnight, the paper then discusses China’s policies on promoting the use of low-carbon energy technologies and nuclear power and efforts to secure stable oil and gas supplies during this transition period. Based on these discussions, the paper provides some recommendations on issues related to energy conservation and pollution control, wind power, nuclear power, clean coal technologies, and overseas oil and gas supplies, and articulates a roadmap for China regarding its climate commitments to 2050.

description: CRISPR systems experience off-target effects that interfere with the ability to accurately perform genetic edits. While empirical models predict off-target effects in specific platforms, there is a gap for a wide-ranging mechanistic model of CRISPR systems based on evidence from the essential processes of target recognition. In this work, we present a first principles model supported by many experiments performed in vivo and in vitro. First, we observe and model the conformational changes and discrete stepped DNA unwinding events of SpCas9-CRISPR target recognition process in a cell-free transcription-translation system using truncated guide RNAs, confirming structural and FRET microscopy experiments. Second, we implement an energy landscape to describe single mismatch effects observed in vivo for spCas9 and Cas12a CRISPR systems. From the mismatch analysis results we uncover that CRISPR class 2 systems maintain their kinetic proofreading mechanism by utilizing intermittent energetic barriers and we show how to leverage the landscape to improve target specificity.

description: We show that standard solar models are in good agreement with the helioseismologically determined sound speed and density as a function of solar radius, the depth of the convective zone, and the surface helium abundance, as long as those models do not incorporate the most recent heavy element abundance determinations. However, sophisticated new analyses of the solar atmosphere infer lower abundances of the lighter metals (like C, N, O, Ne, and Ar) than the previously widely used surface abundances. We show that solar models that include the lower heavy element abundances disagree with the solar profiles of sound speed and density as well as the depth of the convective zone and the helium abundance. The disagreements for models with the new abundances range from factors of several to many times the quoted uncertainties in the helioseismological measurements. The disagreements are at temperatures below what is required for solar interior fusion reactions and therefore do not significantly affect solar neutrino emission. If errors in thecalculated OPAL opacities are solely responsible for the disagreements, then the corrections in the opacity must extend from 2 times 10^6 K (R = 0.7R_Sun)to 5 times 10^6 K (R = 0.4 R_Sun), with opacity increases of order 10%.

description: Current concerns about climate change have led to intensive research attempting to understand how climate-driven stressors affect the performance of organisms, in particular the offspring of many invertebrates and fish. Although stressors are likely to act on several stages of the life cycle, little is known about their action across life phases, for instance how multiple stressors experienced simultaneously in the maternal environment can modulate the responses to the same stressors operating in the offspring environment. Here, we study how performance of offspring of a marine invertebrate (shore crab Carcinus maenas) changes in response to two stressors (temperature and salinity) experienced during embryogenesis in brooding mothers from different seasons. On average, offspring responses were antagonistic: high temperature mitigated the negative effects of low salinity on survival. However, the magnitude of the response was modulated by the temperature and salinity conditions experienced by egg-carrying mothers. Performance also varied among cohorts, perhaps reflecting genetic variation, and/or maternal conditions prior to embryogenesis. This study contributes towards the understanding of how anthropogenic modification of the maternal environment drives offspring performance in brooders.

description: We empirically test delinking of waste dynamics with regard to economic growth and the effectiveness of environmental and specific waste-related policies, by exploiting a newly constructed, integrated waste-economic-policy dataset based on official data for the EU15 for 1995-2007. We find that absolute delinking for waste generation is far from being achieved in the EU despite fairly stringent and longstanding policy commitment that goes back to the mid 1990s, but which however is biased towards waste management and waste disposal rather than waste prevention. Policy as well as country structural factors seem to impact instead on landfill diversion. Nevertheless, country heterogeneity matters: SURE based analyses show that EU average figures often hide high variance. Their results provide food for thought for a future most comprehensive EU waste policy strategy, which is now aimed mainly at landfill diversion, within a framework strongly oriented to allowing countries to decide about the implementation of EU directives.

description: Multi-category support vector machine (MC-SVM) is one of the most popular machine learning algorithms. There are lots of variants of MC-SVM, although different optimization algorithms were developed for different learning machines. In this study, we developed a new optimization algorithm that can be applied to many of MC-SVM variants. The algorithm is based on the Frank-Wolfe framework that requires two subproblems, direction finding and line search, in each iteration. The contribution of this study is the discovery that both subproblems have a closed form solution if the Frank-Wolfe framework is applied to the dual problem. Additionally, the closed form solutions on both for the direction finding and for the line search exist even for the Moreau envelopes of the loss functions. We use several large datasets to demonstrate that the proposed optimization algorithm converges rapidly and thereby improves the pattern recognition performance.

description: The recent crisis was characterized by massive illiquidity. This paper reviews what we know and don't know about illiquidity and all its friends: market freezes, fire sales, contagion, and ultimately insolvencies and bailouts. It first explains why liquidity cannot easily be apprehended through a single statistics, and asks whether liquidity should be regulated given that a capital adequacy requirement is already in place. The paper then analyzes market breakdowns due to either adverse selection or shortages of financial muscle, and explains why such breakdowns are endogenous to balance sheet choices and to information acquisition. It then looks at what economics can contribute to the debate on systemic risk and its containment. Finally, the paper takes a macroeconomic perspective, discusses shortages of aggregate liquidity and analyses how market value accounting and capital adequacy should react to asset prices. It concludes with a topical form of liquidity provision, monetary bailouts and recapitalizations, and analyses optimal combinations thereof; it stresses the need for macro-prudential policies.
