description: Since the mid-1990s new developments in the theory of optimum currency areas have set forth an equilibrium approach that, in contrast with the traditional view stemming from Robert Mundell's seminal paper, considers the optimality criteria as the product of equilibrium forces and therefore endogenous. Notwithstanding their different characteristics, however, these alternative approaches are both useful to tackle different policy issues relating to the transition stage and the long-run operation of monetary unions.

description: Since exclusion at the port of entry is no longer adequate to protect U.S.A. plant resources, increased emphasis is being given to mitigating pest risk at the point of origin of items imported into the U.S.A., i.e. off-shore. In each of recent years the Caribbean Area Office has received an allocation US$ 100,000 from the appropriation to APHIS for pest detection. These funds will be used to support seven priority thrusts: (1) cooperative tracking in the Caribbean Region of pests of quarantine significance using the Off-shore Pest Information System (OPIS), (2) surveillance and biological control of exotic tropical fruit flies, (3) cooperative surveys for the giant African snail, TTAchatina fulica TTBowdich and other dangerous mollusks in the Region, (4) Scirtothrips dorsalis surveillance and mitigation, (5) biological control against the pigeon pea pod fly, Melanagromyza obtusa (Malloch), passionvine mealybug, Planococcus minor (Maskell), and the coffee mealybug, Planococcus lilacinus (Cockerell), (6) provide technical expertise to investigate potential emergent pest problems and provide digital imaging equipment to Caribbean quarantine authorities, and (7) assist in the training of plant protection officers in plant quarantine, in the development of manuals for port of entry inspectors, and updating plant health legislation.

description: An on-farm cultivar evaluation trial for cucumber (Cucumis sativus L.) was conducted to compare differences in plant growth parameters related to fruit characteristics and marketable yield during the summer season. Eight cultivars (Calypso, Cobra, Eureka, Dasher Ii, SMR 58, Marketmore 76, Olympian Fl and Poinsett 76) were transplanted on June 12, 2003 into rows 1.52 m apart and spaced 0.41 m within rows. The trial was established using a randomized complete block design with three replications. Cultivars were harvested on five dates from July 23 to August 10, 2003. Data collected at each harvest included total number of fruits, fresh weight, number of marketable fruits, fruit length, vine length to first flower and fruit. Except for fruit length, differences among cultivars in all measured parameters were significant. New cultivars Cobra and Olympian Fi produced yields that were not significantly (P>0.05) different with common cultivars Calypso and Dasher 2. Cultivar Eureka produced the smallest (202 g) fruit while largest fruits (414 g) were produced by cultivar Olympian F|. Vine length to formation of first fruit was shortest (8.7 cm) with cultivar Olympian Fi and longest (20.9 cm) with cultivar Calypso. In all cultivars, formation of first flower in the vine did not develop into fruit. The study indicates that new and improved cultivars are available to farmers who want to replace old and common cultivars. Best cultivars are Cobra and Olympian F.

description: Historically, agriculture played a major role in the development of the Virgin Islands' economy. As the islands emerged as a major tourist destination in the Caribbean, urbanization encroached on agricultural land. As a result, food prices increased significantly. In an effort to assist families in supplementing the high cost of imported food, the UVI Extension Service's Agriculture and Natural Resources (ANR) Programme introduced a gardening programme to these changing rural communities. The gardening programme is geared to assist residents of low-income communities, elderly residents, youth groups, and residents with limited financial resources and land. With this new approach to agriculture, people also learn unity and community pride and discover that they can make a difference in their surrounding environment.
Money as mumeraire: doctrinal aspects and contemporary relevance

Publisher: name: PSL Quarterly Review

Subjects: subject: Money
subject: E40

description: At the beginning of the twentieth century, most economists took it for granted that the primary function of money is its role as a medium of exchange and that moneyshould consist of, or be backed by, gold, or silver, or both. This paper discusses three writers--Alexander Del Mar, Georg Knapp, and John Maynard Keynes--who took a different tack. By endeavouring to explain what money is, they focused on the capacity of money to have value. In so doing, they gave primacy to the unit-of-account function of money and originated the theory of chartalism. We show that the primacy placed on the numeraire by those writers provides insights into present-day analyses of general equilibrium, neutral money, business cycles, and currency-area formation.

description: Connections between continuous and discrete worlds tend to be elusive. One example is curvature. Even though there exist numerous nonequivalent definitions of graph curvature, none is known to converge in any limit to any traditional definition of curvature of a Riemannian manifold. Here we show that Ollivier curvature of random geometric graphs in any Riemannian manifold converges in the continuum limit to Ricci curvature of the underlying manifold, but only if the definition of Ollivier graph curvature is properly generalized to apply to mesoscopic graph neighborhoods. This result establishes the first rigorous link between a definition of curvature applicable to networks and a traditional definition of curvature of smooth spaces.

description: The oil-exporting countries of the Persian Gulf have failed economically and socially. It is time for a radical new approach to managing oil revenues while oil and gas reserves last. We propose an approach to cut the level of oil revenues available to governments to zero while incorporating a formal "Oil Fund for All Generations". Others have proposed and implemented oil funds but in our proposal the government would (in time) lose all access to oil revenues; by taking easy money away from governments and rulers, waste, corruption, military expenditures and wars will be reduced, there will be better chance of adopting and implementing rational economic policies, and equity across generations may be enhanced. Hope may be slowly restored to a region that has lost hope. JEL Codes: O11, O13, O53, Q32, Q33

description: Two green bean (Phaseolus vulgaris L.) germplasm evaluation trials were conducted during the spring of 1994. Cultivars evaluated in the first trial were 'Blue Lake 274', 'Contender', 'Green Crop', 'Top Crop' and 'Tenderpod'. Stem diameter of plants did not differ significantly among cultivars. 'Tenderpod' plants had a mean height of 33.7 cm and were significantly taller than 'Contender' plants (25.5 cm). The widest pods were produced by 'Top Crop' (0.83 cm), significantly wider than pods from the other cultivars. The longest pods were produced by 'Green Crop' (14.4 cm), and the mean pod weight was significantly superior to 'Tenderpod'. 'Green Crop' was also significantly superior in total yield (7.37 t/ha) to 'Top Crop' and 'Green Pod' with yields of 4.46 and 4.27 t/ha, respectively. Cultivars evaluated in the second trial were 'Contender', 'Derby', 'Dandy', 'Honey Gold', 'Kentucky Wonder' and 'McHarvest'. Plant height and stem diameter were similar for all cultivars. 'Contender' produced pods that were significantly longer (10.9 cm) than those obtained from all other cultivars. Pods from 'Contender' and 'McHarvest' had the highest mean weight (2.7 g), significantly heavier than 'Honey Gotd' (2.0 g) and 'Derby' (1.7 g). 'Dandy', 'McHarvest' and 'Contender' produced the largest quantity of pods. The highest yields were produced by 'Contender', McHarvest', and 'Dandy' with 2.3,2,3 and 2.0 t/ha, respectively.

description: The Free-Energy Principle (FEP) [1-3] has been adopted in a variety of ambitious proposals that aim to characterize all adaptive, sentient, and cognitive systems within a unifying framework. Judging by the amount of attention it has received from the scientific community, the FEP has gained significant traction in these pursuits. The current target article represents an important iteration of this research paradigm in formally describing emergent dynamics rather than merely (quasi-)steady states. This affords more in-depth considerations of the spatio-temporal complexities of cross-scale causality - as we have encouraged and built towards in previous publications (e.g., [4-9]). In this spirit of constructive feedback, we submit a few technical comments on some of the matters that appear to require further attention, in order to improve the clarity, rigour, and applicability of this framework.

description: This project aims to test the hypothesis that an increase in purine biosynthesis and hence ureide biosynthesis in the nodules of transgenic winged bean (Psophocarpus tetragonolobus ), a tropical legume, will result in improved assimilation of fixed nitrogen, and hence increased overall plant productivity under symbiotic conditions. It necessitates: (i) the development of an efficient Agrobaclerium-mcdiaied transformation and regeneration protocol for a tropical legume; (ii) the isolation of purine biosynthetic cDNA clones from a mothbean (Vigna aconitifolia) nodule library by functional complementation of Escherichia coli auxotrophic mutants, and characterization of these clones; and (iii) the production of nodulated transgenic tropical legumes over-expressing glutamine phosphoribosyl amidotransferase (PRAT), the main regulatory enzyme in purine biosynthesis, in the nodules. If the proposed mode! is successful, this strategy can then be applied to improving the yields of regionally important legumes such as kidney bean (Phaseolus vulgaris) and pigeon pea (Cajanas cajart).

description: In the light of recent experimental findings that gap junctions are essential for low level intensity detection in the sensory periphery, the Greenberg-Hastings cellular automaton is employed to model the response of a two-dimensional sensory network to external stimuli. We show that excitable elements (sensory neurons) that have a small dynamical range are shown to give rise to a collective large dynamical range. Therefore the network transfer (gain) function (which is Hill or Stevens law-like) is an emergent property generated from a pool of small dynamical range cells, providing a basis for a "neural psychophysics". The growth of the dynamical range with the system size is approximately logarithmic, suggesting a functional role for electrical coupling. For a fixed number of neurons, the dynamical range displays a maximum as a function of the refractory period, which suggests experimental tests for the model. A biological application to ephaptic interactions in olfactory nerve fascicles is proposed.

description: Lie-Poisson gauge formalism provides a semiclassical description of noncommutative $U(1)$ gauge theory with Lie algebra type noncommutativity. Using the Dirac approach to constrained Hamiltonian systems, we focus on a class of Lie-Poisson gauge models, which exhibit an admissible Lagrangian description. The underlying noncommutativity is supposed to be purely spatial. Analysing the constraints, we demonstrate that these models have as many physical degrees of freedom as there are present in the Maxwell theory.

On floating exchange rates, currency depreciation and effective demand: a comment

subject: E24, F33

description: I certainly agree with the authors on the main point, which is that flexible exchange rates do not result in an automatic adjustment that brings equilibrium with full employment. What I would argue is that flexible exchange rates, however, may be more advantageous than those fixed and that the management of the exchange rate to achieve domestic policy objectives, although useful in some circumstances, it should become the norm in a world in which financial events affect frequently on real variables. In my view, the intervention on the foreign exchange market by the central bank should have a low frequency and used as a signal to prevent upward or downward trend, which of course requires the cooperation and support from other banks central. With regard to the measures compatible with the market on the movement of capital, the use of them should be even more cautious. However, a management for (rare) exception of the exchange rate is certainly possible. JEL Codes: E24, F33

description: Most empirical studies of complex networks do not return direct, error-free measurements of network structure. Instead, they typically rely on indirect measurements that are often error-prone and unreliable. A fundamental problem in empirical network science is how to make the best possible estimates of network structure given such unreliable data. In this paper we describe a fully Bayesian method for reconstructing networks from observational data in any format, even when the data contain substantial measurement error and when the nature and magnitude of that error is unknown. The method is introduced through pedagogical case studies using real-world example networks, and specifically tailored to allow straightforward, computationally efficient implementation with a minimum of technical input. Computer code implementing the method is publicly available.

Farm Management

description: Lablab bean {Ixiblab purpureas (L.) Sweet) is a fast-growing, short-term perennial, tropical legume with a myriad uses for food, feed and green manure. The primary objective of this study was to determine clipping management practices required for optimizing hay and nitrogen yields of the lablab cultivar Rongai in the dry Caribbean. A secondary objective was to compare agronomic trails of eight introduced lablab bean accessions. Plots of lablab bean established on an alkaline fpH>7.8) clay soil (fine carbonitic, isohyperthermic, Typic Rendolls Mollisols) were initially harvested at one of four physiological stages of growth: vegetative (VGT), first visible inflorescence (FVI), full bloom (FB) and green pod (GP) to a 15-cm stubble height. The experimental design was a randomized complete block with three replicates. A subsequent forage harvest was taken at the green pod stage of growth for all treatments because of the propensity of lablab bean to flower early in the cool, shortday photoperiod between the months of December and March, Forage subsamples were processed for leaf/stem ratio and overall dry matter (DM) yield determination. Another subsample was separated into two sequential 15-cm fractions and a top vertical fraction beginning from the base of harvested forage. All forage fractions were dried and analyzed for crude protein (CP). Forage DM yield from the initial harvest followed a typical sigmoid growth curve. It increased from 1,180 kg/ha at the VGT to 3,440 kg/ha at the GP stages of growth. Average DM yield from the aftermath was only 588 kg/ha, regardless of the initial harvest treatment, because of drought and a shorter photoperiod. The leaf fraction constituted 60 and 50% of forage DM for the first three and the GP stages of growth, respectively. Mean leaf CP was 25% and independent of maturity. However, stem CP decreased from 11 to 7% in the initial harvest with maturity but remained constant at 11 % in the aftermath. The basal 15-cm forage fraction constituted 17% of total DM at the VGT but 9-13% at the reproductive stages of plant growth. The upper two fractions (83-91% of forage DM) exhibited CP contents between 15 and 25%. The results suggest that approximately 3,500 kg/ ha of lablab hay with 20% CP content is obtainable in a very dry season. For dual seed and forage production, Rongai was simitar to the best introduced accessions. However, individual lablab bean accessions exhibited either higher seed or forage production than Rongai. More experiments are being conducted to determine lablab performance under favourable rainfall conditions in the Caribbean.
Investigation into struvite solubility, growth and dissolution kinetics in the context of phosphorus recovery from wastewater
Creators: name: Bhuiyan, Md. Iqbal Hossain
Publisher: name: University of British Columbia
Year: 2011

description: The present research was conducted to investigate the mechanisms controlling formation, dissolution and decomposition of the mineral, struvite (MgNH₄PO₄•6H₂O) in the context of phosphorus recovery from wastewater. Solubility, thermodynamics, kinetics and thermal decomposition of struvite were studied in laboratory and wastewater treatment environments to gain knowledge to optimize the phosphorus recovery process from wastewater through struvite crystallization. The thermodynamic solubility products (Ksp) of struvite were determined by extrapolating measured solubility product values to zero ionic strength, with -log Ksp of 13.36(±0.07) at 25⁰C, using an appropriate activity coefficient model. A representative temperature compensation factor (a = 0.0198⁰C-¹) has been derived for electrical conductivity (EC) correction, and a relationship between ionic strength (I) and EC has been developed for anaerobic digester supernatant/centrate samples from five different wastewater treatment plants in western Canada. The metastable region, where nucleation is negligible, for struvite precipitation was explored in this study. This region was used in a kinetics study to suppress nucleation of struvite during growth experiments in a bench-scale fluidized bed reactor (FBR). A linear growth rate model has been tested and proposed, which was found to be effective for struvite growth determination in FBRs. The dissolution processes of struvite were investigated in a batch reactor system using two different theoretical models. The experimental values of struvite dissolution were found to fit well with both models. In a mixed flow-through reactor system, the dissolution rates for struvite pellets were found to increase with the hydrogen ion concentration in the acidic pH, while the rate of dissolution in the alkaline pH was found to increase due to hydroxyl-promoted dissolution. The thermal decomposition study of struvite showed that the simultaneous loss of both ammonia and water molecules from the struvite structure occurred gradually as a function of temperature, rather than as a distinct step. A pilot-scale struvite recovery FBR developed at The University of British Columbia (UBC) was operated, using the knowledge gained from the thermodynamics and kinetics experiments. The pilot-scale FBR was found to be effective in recovering phosphate from anaerobic digester centrate in the form of a nearly pure struvite.

description: In quantum mechanics, the momentum space and position space wave functions are related by the Fourier transform. We investigate how the Fourier transform arises in the context of geometric quantization. We consider a Hilbert space bundle H over the space J of compatible complex structures on a symplectic vector space. This bundle is equipped with a projectively flat connection. We show that parallel transport along a geodesic in the bundle H -> J is a rescaled orthogonal projection or Bogoliubov transformation. We then construct the kernel for the integral parallel transport operator. Finally, by extending geodesics to the boundary (for which the metaplectic correction is essential), we obtain the Segal-Bargmann and Fourier transforms as parallel transport in suitable limits.

description: Keeping a vehicle well-localized within a prebuilt-map is at the core of any autonomous vehicle navigation system. In this work, we show that both standard SIR sampling and rejection-based optimal sampling are suitable for efficient (10 to 20 ms) real-time pose tracking without feature detection that is using raw point clouds from a 3D LiDAR. Motivated by the large amount of information captured by these sensors, we perform a systematic statistical analysis of how many points are actually required to reach an optimal ratio between efficiency and positioning accuracy. Furthermore, initialization from adverse conditions, e.g., poor GPS signal in urban canyons, we also identify the optimal particle filter settings required to ensure convergence. Our findings include that a decimation factor between 100 and 200 on incoming point clouds provides a large savings in computational cost with a negligible loss in localization accuracy for a VLP-16 scanner. Furthermore, an initial density of $\sim$2 particles/m$^2$ is required to achieve 100% convergence success for large-scale ($\sim$100,000 m$^2$), outdoor global localization without any additional hint from GPS or magnetic field sensors. All implementations have been released as open-source software.

description: We show how the measurement induced model of quantum computation proposed by Raussendorf and Briegel [Phys. Rev. Letts. 86, 5188 (2001)] can be adapted to a nonlinear optical interaction. This optical implementation requires a Kerr nonlinearity, a single photon source, a single photon detector and fast feed forward. Although nondeterministic optical quantum information proposals such as that suggested by KLM [Nature 409, 46 (2001)] do not require a Kerr nonlinearity they do require complex reconfigurable optical networks. The proposal in this paper has the benefit of a single static optical layout with fixed device parameters, where the algorithm is defined by the final measurement procedure.

No fertilizer (FO) and compound fertilizer (8-18-32) providing 40,90 and 160 kg/ha NPK (Fl) were the split plots. Maximum germination, 11 days after sowing was 95,1 and 90.2 (SED = 1.98; 17 df) for leucaena and moringa respectively. Moringa tended to be shallow rooted (26.8 cm vs 60.1 cm for leucaena, SED = 1.49; 5 df) but it had similar root biomass as leucaena (137.3 vs 132.8 g/m2, P>0.05). Shoot biomass (forage yield) was significantly higher (PcO.Ol ) for leucaena ( 196.4g mJ ) than for moringa (145.3 g/m2). However, the response of moringa to applied fertilizer was two (for root biomass) to five (for shoot biomass) times that of leucaena. It was concluded that, with its good establishment capacity and high responsiveness to fertilizer application, moringa has potential as a multipurpose tree for forage production.

description: This paper discusses the relative advantages of floating exchange rates vis-a-vis a pegged exchange rate regime, with special emphasis on the implications foreffective demand. More particularly, it explores whether a currency depreciationhas a beneficial effect on aggregate demand and hence on employment. The authors argue that this issue is central to the whole principle of effective demand, and that the idea of a currency depreciation being able to stabilize effective demand is to a large extent analogous to the claim that (downward) flexibility of nominal (and real) wages can ensure full employment. Accordingly, the relationship between downward wage flexibility and effective demand is analysed and the hypothesis that exchangerate flexibility can have stabilizing properties when exogenous shocks of various kinds are taken into account is critically assessed both theoretically and empirically. The paper concludes that while exchange rate flexibility can be a useful instruments, it may have some side effects that should be taken into account. JEL Codes: E24, F33

description: This study shows that, among the two crisis periods of 1997, January-March and September-November, the spot market interventions were effective in stabilizing the Korean currency in the first period, whereas there is no evidence that the forward market interventions were effective in either of these two periods. If anything, the forward market interventions resulted in a destabilization of the exchange rate. This result may be due to excessive use of forward market interven-tions from 20th October, when the forward premium tended to show amplifying movement. Although it was clear that the Korean won was no longer defendable by forward market interventions, the Korean monetary authorities intervened in vain to defend the Korean currency. The forward market intervention seemed to be heavily used because the BOK believed its efficacy of a bear squeeze and wanted to camouflage the drain in foreign reserves. However, wasting foreign reserves in this operation proved too costIy for the BOK and the Korean economy. The result of this study suggests that, only when forward premiums are maintained within some margin, forward market interventions may be an effective instrument for stabilizing the foreign exchange market; otherwise it can create unwanted results, precipitating only the collapse of the exchange rate and aggravating the drain of foreign reserves, especially in a crisis period.

Productivity Analysis

description: One hundred and twenty weaned Barbados Blackbelly lambs were reared in confinement in batches of 20 between October 1993 and April 1995. They were fed a by-product ration which consisted of poultry litter, wheat middlings, rice bran, molasses and a mineral/ vitamin mix. Data collected were used to measure parameters such as average daily gain (ADG), average daily feed intake (ADI), feed efficiency (FE); carcass measurements were also evaluated. The liveweight for each animal was recorded immediately before slaughter and the head, skin, feet, paunch, heart and liver were also weighed. The carcass was divided into fore and hindsaddles at the 12th and 13th rib. ADG, ADI and FE were 0.094, 1.2 and 12.9 kg respectively. Rams were significantly heavier (P < 0.001) at slaughter than ewes and the skin and paunch of rams were also significantly heavier (P < 0.001 ). However there was no significant difference (P > 0.05) in weight of heads and livers of rams and ewes. Cost per unit gain was US$1.67. ADG for ram and ewe lambs was 100 and 87 g respectively. Average fasted slaughter and carcass weights were 30.8 ± 3.94 and 15.4 ± 2.2 kg respectively with a dressing out of 50%. Fasted weight was approximately 92% of fresh liveweight. There was an additional 7% shrinkage between hot and cold carcass weight and fore and hindsaddles were 51 and 43% of chilled carcass weight respectively. Legs, shoulders and racks represented 60,56 and 23% of hind and foresaddles respectively. The head, skin, and paunch were 5, 13, and 24.6% of fasted liveweight while the liver was 9.6% of chilled carcass weight.

description: This study examines the monthly returns in Turkish and American stock market indices to investigate whether these markets experience abnormal returns during some months of the calendar year. The data used in this research includes 212 observations between January 1996 and August 2014. I apply statistical summary analysis, decomposition technique, dummy variable estimation, and binary logistic regression to check for the monthly market anomalies. The multidimensional methods used in this article suggest weak evidence against the efficient market hypothesis on monthly returns. While some months tend to show abnormal returns, there is no absolute unanimity in the applied approaches. Nevertheless, there is a strikingly negative May effect on the Turkish stocks following a positive return in April. Stocks tend to be bullish in December in both markets, yet we do not observe anya significant January effect is not observed.

description: The present study examined the effects of display complexity and cueing predictability on vigilance performance and measures of subjective stress and workload while monitoring maternal fetal heart rate (MFHR) signals. Seventy-two undergraduate students from Old Dominion University performed a simulated MFHR task and were randomly assigned to monitor one, two, or four displays for critical signals. Half of the participants received cues that were 83'/o reliable, and the other half received cues that were 55'/o reliable. Stress and workload were assessed before and after the vigil. It was hypothesized that detection ability would be lower, and the decrement would become more pronounced as the number of displays to be monitored increased and the reliability of cueing decreased. Perceived stress and workload were also expected to increase from pre-vigil to postvigil. Results showed that participants detected fewer critical signals as time on task progressed. Further, as the number of displays increased, correct detections decreased but did not interact with time. There were no differences between the cueing reliability conditions, but perceived stress and workload did increase from previgil to postvigil. These results show that under relatively ideal monitoring conditions, individuals struggle to detect critical changes in MFHR signals, and their difficulties increase over time. Moreover, these findings raise concerns about the ability of health care providers to monitor MFHR signals in genuine clinical settings.

description: Certain strongly interacting dark matter candidates could have evaded detection, and much work has been done on constraining their parameter space. Recently, it was shown theoretically that the scattering cross section for $m_χ\gtrsim 1$ GeV pointlike dark matter with a nucleus cannot be significantly larger than the geometric cross section of the nucleus. This realization closes the parameter space for pointlike strongly interacting dark matter. However, strongly interacting dark matter is still theoretically possible for composite particles, with much parameter space open. We set new, wide-ranging limits based on data from a novel detector at the University of Chicago. Backgrounds are greatly suppressed by requiring coincidence detection between two spatially separated liquid-scintillator modules. For dark matter ($v \sim 10^{-3}$c), the time of flight would be $\sim 2~μ{\rm s}$, whereas for cosmic rays, it would be $\sim 2~{\rm ns}$. We outline ways to greatly increase sensitivity at modest costs.

description: Additional file 1: Table S1. Calculation of the mean N-value of each plot from the indicator values of Landolt et al. [17] and its frequency based on Braun-Blanquet [1]. For each plant (in this example of plot 1 (Table 1)) the Braun-Blanquet frequency was increased by 1 to obtain values from 1 to 5. This number was multiplied by the Landolt-indicator value. The mean N-value per plot results in the sum of these products divided by the sum of the new frequency values. The calculation steps are given below.

description: Radiative corrections to E1 matrix elements for ns-np transitions in the alkali metal atoms lithium through francium are evaluated. They are found to be small for the lighter alkalis but significantly larger for the heavier alkalis, and in the case of cesium much larger than the experimental accuracy. The relation of the matrix element calculation to a recent decay rate calculation for hydrogenic ions is discussed, and application of the method to parity nonconservation in cesium is described.
Stress testing credit risk: experience from the italian FSAP

description: In this paper we describe the methodologies that can be used for stress testing credit risk providing some applications to the Italian banking system.Within the FSAP for Italy, stress tests examined the impact of a variety of shocks on the nine major Italian banking groups. The tests were performed using both top-down and bottom-up approaches, which provided comparable results. For the sensitivity analysis, the size of the shocks to assess market risk, sovereign risk, interest rate rÌsk in the banking book and liquidity risk was in line with those ap-plied in other FSAPs for euro area countries, while the credit risk shock exceeded the largest historical shock. In addition, the impact of various adverse macroeconomic scenarios has been assessed. Specifical-ly, an adverse macro scenario in which oil prices reach USD 85-90 per barrel causing a global slow down and global equity prices decrease by 30% has the largest impact. Overall, stress test results suggest that the Italian banking sector is resilient to shocks. Profits appear in most cas-es sufficient to cover 10sses arising from the shocks calibrated. Existing capitaI buffers remain comfortably above the minimum regulatory sol-vency ratios. The implementation of macroeconomic stress-testing pro-grammes such as those underlying the FSAPs has advanced the devel-opment of internally consistent stress testing procedures. However, the state of the art is still evolving and further work in this field will allow relaxing less realistic assumptions, further improving the methodologies and making results more reliable.
