Disseminated Rhizopus microsporus infection cured by salvage allogeneic hematopoietic stem cell transplantation, antifungal combination therapy, and surgical resection. Transpl Infect Dis 2010. All rights reserved Abstract: Invasive Zygomycetes infection complicating prolonged neutropenia is associated with high mortality in the absence of immune recovery. We report a patient who developed disseminated zygomycosis due to Rhizopus microsporus during induction chemotherapy for acute myeloid leukemia. Rescue allogeneic hematopoietic stem cell transplantation (allo-HSCT) was performed as her only chance of cure of this infection and to treat refractory leukemia. Posaconazole combined with liposomal amphotericin B contained the zygomycosis during prolonged neutropenia due to allo-HSCT followed by intense immunosuppression for grade IV acute graft-versus-host disease. Surgical removal of all infected sites after immune recovery, with prolonged posaconazole treatment, ultimately cured the infection. New combination antifungal therapies might sufficiently control disseminated zygomycosis to allow allo-HSCT to be performed, assuring life-saving immune recovery. Surgery appears to be necessary for definite cure of these infections.

Detection of millimetric deformation using a terrestrial laser scanner: experiment and application to a rockfall event

Abstract. Terrestrial laser scanning (TLS) is one of the most promising surveying techniques for rockslope characteriza- tion and monitoring. Landslide and rockfall movements can be detected by means of comparison of sequential scans. One of the most pressing challenges of natural hazards is com- bined temporal and spatial prediction of rockfall. An outdoor experiment was performed to ascertain whether the TLS in- strumental error is small enough to enable detection of pre- cursory displacements of millimetric magnitude. This con- sists of a known displacement of three objects relative to a stable surface. Results show that millimetric changes cannot be detected by the analysis of the unprocessed datasets. Dis- placement measurement are improved considerably by ap- plying Nearest Neighbour (NN) averaging, which reduces the error (1σ ) up to a factor of 6. This technique was ap- plied to displacements prior to the April 2007 rockfall event at Castellfollit de la Roca, Spain. The maximum precursory displacement measured was 45 mm, approximately 2.5 times the standard deviation of the model comparison, hampering the distinction between actual displacement and instrumen- tal error using conventional methodologies. Encouragingly, the precursory displacement was clearly detected by apply- ing the NN averaging method. These results show that mil- limetric displacements prior to failure can be detected using TLS.

Caracterització radiològica i dosimètrica ambiental d'una planta de producció de fosfat bicàlcic

The production of dicalcium phosphate are included in the list of industries classified as NORM in Euratom 29/96. The aim of this study is to determine the con-centrations of specific flows and their variability over time of 226Ra, 210Pb and 210Po in the inputs and out-puts of the production process. Also classified areas of the plant and the workers according to the radio-logical risk and radiation protection measures have been proposed. The results show that the rock phos-phate has a high specific activity of the 226Rn, 210Po and 210Pb in secular equilibrium (1500-2000 Bq • kg-1) but the outputs of the process will distort the secu-lar equilibrium. The only shortfall is the flow balance of 226Ra, which accumulates in the process. The dis-tribution of the dose in the plant concentrates on the area of reactor tanks and slop pipes as regards exter-nal irradiation dose and the grinding zone, the area of packaging and loading area so respects dose inhaled. We propose a signaling areas, cleaning and replace-ment of old equipment in the facilities and radiological safety of the maintenance staff.

Selected configuration interaction with truncation energy error and application to the Ne atom

Selected configuration interaction (SCI) for atomic and molecular electronic structure calculations is reformulated in a general framework encompassing all CI methods. The linked cluster expansion is used as an intermediate device to approximate CI coefficients BK of disconnected configurations (those that can be expressed as products of combinations of singly and doubly excited ones) in terms of CI coefficients of lower-excited configurations where each K is a linear combination of configuration-state-functions (CSFs) over all degenerate elements of K. Disconnected configurations up to sextuply excited ones are selected by Brown's energy formula, ΔEK=(E-HKK)BK2/(1-BK2), with BK determined from coefficients of singly and doubly excited configurations. The truncation energy error from disconnected configurations, Δdis, is approximated by the sum of ΔEKS of all discarded Ks. The remaining (connected) configurations are selected by thresholds based on natural orbital concepts. Given a model CI space M, a usual upper bound ES is computed by CI in a selected space S, and EM=E S+ΔEdis+δE, where δE is a residual error which can be calculated by well-defined sensitivity analyses. An SCI calculation on Ne ground state featuring 1077 orbitals is presented. Convergence to within near spectroscopic accuracy (0.5 cm-1) is achieved in a model space M of 1.4× 109 CSFs (1.1 × 1012 determinants) containing up to quadruply excited CSFs. Accurate energy contributions of quintuples and sextuples in a model space of 6.5 × 1012 CSFs are obtained. The impact of SCI on various orbital methods is discussed. Since ΔEdis can readily be calculated for very large basis sets without the need of a CI calculation, it can be used to estimate the orbital basis incompleteness error. A method for precise and efficient evaluation of ES is taken up in a companion paper

Contrasting the form and use of reformulation markers

This paper deals with the form and use of reformulation markers in research papers written in English, Spanish and Catalan. Considering the form and frequency of themarkers, English papers tends to prefer simple fixed markers and includes less reformulators than Spanish and Catalan. On the contrary, formal Catalan and Spanish papers include more markers, some of which are complex and allow for some structural variability. As for use, reformulation markers establish dynamic relationships between portions of discourse which can be identified in our corpus with expansion, reduction, and permutation. The analysis of the corpus shows that English authors usually reformulate to add more information to the concept (expansion), whereas Catalan and Spanish authors reduce the contents or the implicatures of the previous formulation more frequently than English.

Social bases of changing income distributions

On the backdrop of very little sociological concern with rising income inequality, this paper examines how key changes in sociodemographic behaviour may help shed additional light on changes in household income distribution and especially on long-term income dynamics and inter-generational mobility. The paper argues that the joint effect of rising marital homogamy in terms of human capital and labour supply contributes generally to widen the income gap between households. Only uner very restrictive conditions, namely when the labour supply of low educated women grows dis-proportionally fast, will women's earnings contribute to more equality. Finally, the paper suggests that women's rising employment commitments contribute positively to equalizing the opportunity structure both via the income effect and if quality care is available, also via more homogenous cultural and cognitive stimulation of children. Mother's work does not generally have adverse effects for children's development.

Contribuição das Emissões de Poluentes de Veículos para a Poluição Atmosférica Urbana

O aumento do número de automóveis nas últimas décadas veio intensificar a poluição do ar, principalmente nos centros urbanos. É necessário encontrar soluções criativas e estáveis para a adequação dos numerosos fluxos de veículos, de modo a promover um ambiente urbano que propicie uma melhor qualidade de vida para as suas populações. Neste sentido, no presente estudo são descritos os processos de formação e emis-são/dispersão dos poluentes emitidos pelos veículos automóveis, bem como os métodos de controlo para redução das emissões produzidas por esses veículos. O tráfego rodoviário desse local foi caracterizado em termos de volume, cilindrada, tipo de combustível, ano de fabrico e categoria (ligeiro ou pesado), com vista à modelação da emissão dos respectivos poluentes a partir de modelos de emissão próprios para o efeito - CORINAIR e HBEFA. Com base nos dados da emissão, foi calculada a dispersão destes poluentes no centro urba-no em causa a partir de uma norma própria para o efeito – AUSTAL2000. Foram efectuadas medições de poluentes no local seleccionado para este estudo para a afe-rição dos resultados da modelação da dispersão resultante dos modelos de emissão e dis-persão usados. Foram ainda efectuadas medições das condições meteorológicas que servi-ram como dados de entrada para o cálculo da dispersão. O resultado final, “mapas de qualidade do ar” obtidos para os diferentes dias típicos da semana, são apresentados e analisados com base nas fontes retratadas e ainda nos valores de poluição de fundo obtidos a partir de uma estação de referência (Ervedeira).

Turnout, political preferences and information: Experimental evidence from Perú

Electoral institutions that encourage citizens to vote are widely used around the world. Yet littleis known about the effects of such institutions on voter participation and the composition of the electorate.In this paper, I combine a field experiment with a change in Peruvian voting laws to identify theeffect of monetary (dis-)incentives on voting. Using the random variation in the fine for abstention andan objective measure of turnout at the individual level, I estimate the elasticity of voting with respectto cost to be -0.21. Consistent with the theoretical model presented, the reduction in turnout inducedby the reduction in the fine is driven by voters who (i) are in the center of the political spectrum, (ii)are less interested in politics, and (iii) hold less political information. However, voters who respondto changes in the cost of abstention do not have different preferences for policies than those who voteregardless of the cost. Further, involvement in politics, as measured by the decision to acquire politicalinformation, seems to be independent of the level of the fine. Additional results indicate that thereduction in the fine does not affect the incidence of vote buying, but increases the price paid for avote.

A genetic isolation gradient of populations of the Balearic green toad (Bufo balearicus) follows rising eastward fragmentation of the rural landscapes on the island of Menorca.

We present the first approach to the genetic diversity and structure of the Balearic toad (Bufo balearicus Boettger, 1880) for the island of Menorca. Forty-one individ- uals from 21 localities were analyzed for ten microsatellite loci. We used geo-refer- enced individual multilocus genotypes and a model-based clustering method for the inference of the number of populations and of the spatial location of genetic dis- continuities between those populations.¦Only six of the microsatellites analyzed were polymorphic. We revealed a northwest- ern area inhabited by a single population with several well-connected localities and another set of populations in the southeast that includes a few unconnected small units with genetically significant differences among them as well as with the individ- uals from the northwest of the island. The observed fragmentation may be explained by shifts from agricultural to tourism practices that have been taking place on the island of Menorca since the 1960s. The abandonment of rural activities in favor of urbanization and concomitant service areas has mostly affected the southeast of the island and is currently threatening the overall geographic connectivity between the different farming areas of the island that are inhabited by the Balearic toad.

Subsampling inference in threshold autoregressive models

This paper discusses inference in self exciting threshold autoregressive (SETAR)models. Of main interest is inference for the threshold parameter. It iswell-known that the asymptotics of the corresponding estimator depend uponwhether the SETAR model is continuous or not. In the continuous case, thelimiting distribution is normal and standard inference is possible. Inthe discontinuous case, the limiting distribution is non-normal and cannotbe estimated consistently. We show valid inference can be drawn by theuse of the subsampling method. Moreover, the method can even be extendedto situations where the (dis)continuity of the model is unknown. In thiscase, also the inference for the regression parameters of the modelbecomes difficult and subsampling can be used advantageously there aswell. In addition, we consider an hypothesis test for the continuity ofthe SETAR model. A simulation study examines small sample performance.

A process approach to the utility for gambling

This paper argues that any specific utility or disutility for gamblingmust be excluded from expected utility because such a theory is consequentialwhile a pleasure or displeasure for gambling is a matter of process, notof consequences. A (dis)utility for gambling is modeled as a process utilitywhich monotonically combines with expected utility restricted to consequences.This allows for a process (dis)utility for gambling to be revealed. Asan illustration, the model shows how empirical observations in the Allaisparadox can reveal a process disutility of gambling. A more general modelof rational behavior combining processes and consequences is then proposedand discussed.

Irreversible investment in stochastically cyclical markets

This paper presents a new framework for studying irreversible (dis)investment whena market follows a random number of random-length cycles (such as a high-tech productmarket). It is assumed that a firm facing such market evolution is always unsure aboutwhether the current cycle is the last one, although it can update its beliefs about theprobability of facing a permanent decline by observing that no further growth phasearrives. We show that the existence of regime shifts in fluctuating markets suffices for anoption value of waiting to (dis)invest to arise, and we provide a marginal interpretationof the optimal (dis)investment policies, absent in the real options literature. Thepaper also shows that, despite the stochastic process of the underlying variable has acontinuous sample path, the discreteness in the regime changes implies that the samplepath of the firm s value experiences jumps whenever the regime switches all of a sudden,irrespective of whether the firm is active or not.

Noções da alteridade, do “outro”

Na perspectiva de Dussel (1997 apud Guareschi, 2002), desenvolvida por Pedrinho Guareschi (2002), a alteridade é analisada segundo uma dimensão relacional pois, a existência do Um implica a do “Outro” dentro do contexto da relação social entre seres humanos. Por outro lado, o “outro” é construído sob duas formas: na primeira “outro” como “di-ferente”, na segunda como dis-tinto” (Dussel, 1997a apud Guareschi, 2002). Em que o “outro” como “di-ferente” provém do latim, sendo que, “dis (…) significa divisão ou negação; ferre significando levar com violência, arrastar. Nesse sentido, o diferente é o arrastado desde a identidade original e coloca-se como o oposto” (Dussel, 1997a apud Guareschi, 2002:157). Por outro lado, “outro” visto como “dis-tinto”, de dis e tinguere em latim, porém nessa concepção, ainda que ele seja um “outro”, não é “arrastado para fora”, pelo contrário, possui a sua identidade e estabelece com o “‘mesmo’ relações de diálogo, construtivas, de conversão” (Dussel, 1997a apud Guareschi, 2002:157).
