In this paper, we offer a short overview of a number of methods that have been reported in the computational-mechanics literature for quantifying uncertainties in engineering applications. Within a probabilistic framework, we describe the characterization of uncertainties using mathematical statistics methods, the propagation of uncertainties through computational models using either Monte Carlo sampling or stochastic expansion methods, and the sensitivity analysis of uncertainties using variance- and differentiation-based methods. We restrict our attention to nonintrusive methods that can be implemented as wrappers around existing computer programs, thus requiring no modification of the source code. We include some recent advances in the propagation and sensitivity analysis of uncertainties that are characterized by arbitrary probability distributions that may exhibit statistical dependence. Finally, we demonstrate the methods integrated in the proposed overview through a nonlinear engineering application relevant to metal forming. [less ▲]

This paper reviews a broad range of performance evaluation tools available for social enterprises and compare them. Therefore we develop an analytical framework based on the specificities of social enterprises and on performance management theory. This framework incorporates the most relevant criteria that will allow to determine whether a tool includes the ideal characteristics to evaluate performance in social enterprises and to what extent. Three of the most representative and widespread tools, the balanced scorecard, the social return on investment and the global reporting initiative framework, are then studied and compared through this analytical framework.

Rice is a primary food source, vital vehicle in dealing with food security and eradicating poverty. In Benin rice is becoming increasingly important and its production and processing tasks are divided on the basis of gender, with women being responsible for much of the drudgery involved in processing. To have an overview of gender and socio-economic dimensions of local rice processing in Benin, a study was conducted in the north and south of Benin with 240 smallholder rice processors randomly selected. In addition to structured interviews and weekly report sheets, the participatory assessment on sustainable livelihood approach was used to appreciate the different states of their financial, social, human, natural and physical capitals assets. Rice processors are mostly women (67% in the whole sample). Men are more representative in white rice processing while women are more representative in parboiled rice processing. Women rice processors have less acces to formal learning source and have bad practices during white rice processing. The traditional rice parboiling methods that don’t lead to good quality rice is prevalence. The main actors of local rice commercialization are the rice producers; the bodies of the Ministry of Agriculture; Famers Organisation and smallholder local rice processors who are generally young women. During local rice commercialization, women are more representative in the sale without contract in the processing village while men are more representative in the sale under a contract. The overall state of capitals is low with better scores in human, physical and natural capitals stocks for men and in social capital for women. [less ▲]

SPICAV/SOIR is a suite of three spectrometers in the UV and IR range flying on ESA Venus Express orbiter, dedicated to the study of the atmosphere of Venus : UV (110-320 nm), Vis-Nir (0.65-1.65 µm), and mid IR (2.3-4.4 µm). The UV spectrometer discovered a high altitude layer of SO2 ( 85-105 km), apparently correlated with the density of haze particles. Ozone is detected for the first time in the atmosphere of Venus. The night side γ and δ bands of NO intensities are maximal at 2 am (influence of super-rotation), while the O2 emission mapped simultaneously by Virtis peaking at 95 km altitude ( 10 km below NO emission) is centered at midnight, a puzzle for general circulation models. The hot hydrogen component of the exosphere, extending at more than 30,000 km, is variable. The SPICAV VIS-IR sensor (0.7-1.7 μm, resolution 0.5-1.2 nm) employs a pioneering technology: acousto-optical tunable filter (AOTF). Day side observations indicate a variable latitude distribution of cloud top altitude (decreasing toward the pole) and water vapor mixing ratio. The SOIR spectrometer is a new Solar Occultation IR spectrometer in the range λ=2.2-4.3 µm, with a spectral resolution λ/Πλ>20,000, the highest ever flown in a planetary mission. This new concept includes a combination of an echelle grating and an AOTF crystal to sort out one order at a time. Vertical profiles of CO, HDO, H2O, HCl, SO[SUB]2[/SUB], CO[SUB]2[/SUB] isotopes and temperature are regularly retrieved, as well as aerosols. The CO mixing ratio (80-130 km), a tracer of atmospheric exchange from thermosphere to lower atmosphere, is 10 times less than the VIRA model prescription, showing also some time variability.

This talk broadly focuses on the identification of differential item functioning (DIF) and differential test functioning (DTF). After a short introduction of the key concepts, most-known methods to detect DIF and DTF with dichotomously or polytomously scored items, and between two or more than two groups, are presented. Both parametric (i.e. IRT) and nonparametric (i.e. score-based) methods are described in a non-technical way. Several potential applications to PISA surveys are discussed. [less ▲]

Background. The Belgian Section of Transplant Coordinators, created in 1997 under the auspices of the Belgian Transplant Society, is in charge of the collection of the national data about donor/procurement activities. Methods. Data are collected in all Belgian transplant centers. An annual report is finalized by combining these data with data from the Eurotransplant database. Results. An increase of both potential donors (n 501, 14.4%) and effective donors (n 273, 16.7%) was observed in 2006 versus 2005. Among effective donors, 28 were non–heart-beating donors (10.25%). Overall donor ratio was 26.26 donors per million inhabitants. Within potential donors, absence of organ harvesting was due to medical contraindications (28%), family refusal (13%), or legal refusal (2%). Donor mean age was 46.4 years and mean organs/donor was 3.21 1.7. An overall reduction of Belgian waiting lists was observed in 2006 as compared with 2005 ( 5.7% for kidney, 25.7% for liver, 9.4% for heart, 6.7% for lung, and 11.7% for pancreas), while waiting list mortality was 18% for liver, 11% for heart, and 7% for lung. As compared with 2005, transplant activities increased for kidney (n 485, 24.3%), heart lungs (n 73, 7.3%), and lungs (n 83, 39.4%) but decreased for liver (n 236, 2.1%). Living donation represented 8.45% for kidney ( 28.1% vs 2005) and 8% for liver transplantation ( 29.6%). Conclusion. Globally, a marked increase of procurement and transplant activities was observed in 2006, allowing to limit waiting list and waiting list mortality. Further increase of living donor activity and non–heart-beating donation remains necessary to extend the donor pool. [less ▲]

Computerized adaptive testing (CAT) is an efficient method to administer psychometric or educational tests and questionnaires. Unlike the standard fixed (“paper-and-pencil”) tests, items in a CAT are iteratively and optimally selected within a bank of available items, on the basis of previously administered items and the current ability estimate of the examinee. This general approach has several assets with respect to fixed tests: it reduces the risk of fraud, it allows for individualized questionnaires according to the examinee’s ability level, and fewer items must be administered to reach the same level of precision in the ability estimates. The purpose of this talk is threefold. First, a general overview of CAT is proposed and its main principles are quickly outlined. Second, a recently developed R package, called catR, is briefly presented and its functionalities are described. Finally, two applications are discussed. The first application is a live demonstration of catR, by using its by-default item bank about English aptitude assessment, and several CAT options. The second application focuses on the on-line testing platform Concerto, a web interface for the development and testing of CAT sessions that uses catR as underlying computational package. The R package catR was jointly developed with Gilles Raîche (Université du Québec à Montréal, Canada). The platform Concerto is under development by The Psychometrics Centre (Cambridge University, UK) under the supervision of Michal Kosinski and John Rust. [less ▲]

Historical data indicate that pituitary tumors represent 10% of intracranial tumors, while adenomas are noted in approximately 14-23% of normal subjects on autopsy or magnetic resonance imaging (MRI). About 2.5% of these tumors stain positive for GH in histopathologic studies. In contrast, the prevalence of clinically diagnosed acromegaly is lower at 36-69 per million population. Ongoing studies indicate that the actual prevalence of acromegaly in the community may be higher than previous epidemiologic data suggest. Acromegaly can occur both sporadically and in the setting of familial conditions, such as multiple endocrine neoplasia type 1 (MEN1) and Carney complex (CNC). Isolated familial somatotropinoma has been described and newer data suggest that acromegaly may also occur in non-MEN1/CNC families in combination with other pituitary tumor phenotypes. [less ▲]
