IT organization design, consisting of IT governance (decision rights) and IT organization structure, is believed to affect organizational performance. This paper describes the IT organization design choices of the 50 U.S. state governments. Significant movement toward greater centralization was observed (particularly for IT services). States appeared to have adopted IT organization design innovations previously pioneered in the private sector, contrary to conventional wisdom founded on well-documented differences between the two sectors. Two commonly used explanations of IT organization design choices were examined for their ability to account for the unexpected findings — contingency and institutional theories. Both explanations were partially successful in explaining the results, but further theoretical development is needed to integrate those theories and more empirical research is needed to advance the field’s knowledge of IT organization design.

InnovatIve technologIes In radIatIon oncology SUMMARY : At present, radiation oncology is again flourishing thanks to the development of highly accurate techniques as intensity modulated radiation therapy, stereotactic radiation therapy and hadrontherapy. These therapeutic modalities are made possible by the advent of image guided radiation therapy and respiratory gating that allows a better patient repositioning during the irradiation and between fractions. Nowadays, thanks to these recent technological advances, one can more easily conceive dose escalation, hypofractionation and combined treatment of radiation with sensitizing drugs and this together with a better protection of normal tissue aiming at, simultaneously, improved tumour control and better quality of life. This article describes these innovative technologies that, when integrated to other anti-tumoral therapeutic modalities, seem to be very promising. Keywords : - [less ▲]

Along with technical developments, international exchanges of genetic material (e.g., frozen semen, embryos) have increased since the 1970s. However, genetic evaluations are traditionally based on phenotypic and genealogical data which are internally recorded, i.e., within well defined borders. Because imported (i.e., external) genetic material is usually strongly selected in their respective populations, internal genetic evaluations for external animals could be biased and less accurate if external data used for their selection is ignored. Moreover, comparison of internal and external animals based on their internal and external estimates of genetic merit is needed to select and potentially import the most suitable ones according to the internal breeding goal. However, such comparison is usually not possible among internal and external genetic evaluations due, e.g., to differences among units of measurement. Thereby, several approaches and algorithms have been developed to render internal and external genetic evaluations comparable, and to combine or blend phenotypic and genealogical data and external information, i.e., estimates of genetic merit and associated reliabilities. Furthermore, the recent development of genomic selection also increased needs for combining phenotypic, genealogical and genomic data and information. Therefore, the aim of this thesis was first to develop innovative algorithms to combine diverse sources of phenotypic, genealogical and genomic data and information, and second to test them on simulated and real data in order to check their correctness. Based on a Bayesian view of the linear mixed models and addressing several issues highlighted by previous studies, systems of equations combining simultaneously diverse sources of data and external information were developed for (multivariate) genetic and single-step genomic evaluations. Double counting of contributions due to relationships and due to records were considered as well as computational burden. The performances of the developed systems of equations were evaluated using simulated datasets and real datasets originating from genetic (genomic) evaluations for Holstein cattle and for show jumping horses. The different results showed that the developed equations integrated and blended several sources of information in a proper way into a genetic or a single-step genomic evaluation.It was also observed that double counting of contributions due to relationships and due to records was (almost) avoided. Furthermore, more reliable estimates of genetic merit were also obtained for external animals and for their relatives after integration of external information. Also, the developed equations can be easily adapted to complex models, such as multivariate mixed models. Indeed, it was shown that external information correlated to the internal phenotypic traits was properly integrated using the developed equations. Finally, research of this thesis led to the development of a genomic evaluation system for Holstein cattle in the Walloon Region of Belgium for production traits, as well as for other traits, like somatic cell score. Based on the research of this thesis, future research topics, e.g., concerning integration of correlated external information and of genomic information, were finally presented. [less ▲]

Selenium (Se) is a trace element which is both essential and toxic depending on its concentration and its chemical form. Se-rich yeast is one of the most popular Se source for supplementation. The classical method of speciation is related to multidimensional liquid chromatography (LC) hyphenated to mass spectrometry (MS) Recent advances in Se speciation led to greatly improve the Se speciation in these samples but isomers identification and quantification remain challenging. This work focuses on the elaboration of an innovative analytical strategy for the detection and the structural elucidation of isobaric selenium compounds present in Se-rich yeast. A specific complex formation agent acts as a chemical probe for the detection of chemical function. The addition of a complexing agent can improve the discrimination between structural or functional Se isomers using ion mobility techniques as Ion Mobility Spectrometry (IMS) by increasing the molecular weight (i.e. the m/z ratio in MS) and the collision cross section of a target ion after selective complexation. This Ion Mobility orthogonal separation improves the structural elucidation. Crown ethers used as shifting agents can specifically form complexes with primary amines. The addition of crown ether to different low molecular weight fractions obtained by multidimensional LC of a water extract from Se-rich yeast permitted to detect Se isomers and confirmed their structure using IMS.

Selenium (Se) is a trace element which is both essential and toxic depending on its concentration and its chemical form. Selenomethionine (SeMet) is one of the widely used selenium standard during Selenium speciation studies. This work was focused on the elaboration of an analytical strategy for the detection and the structural elucidation of an isobaric Se interference, which is found in standard solutions of SeMet by high resolution mass spectrometry (Rm/Δm > 20.000). The structural elucidation of these compounds requires the isolation of the respective parent ion. Nevertheless, the mass difference between SeMet and its interference is less than 0.02Da which is well below the window selection of conventional techniques in mass spectrometry (Quadripole, ion trap). The empirical formula and double bound equivalent (DBE) of these ions suggest different tridimensional structures which lead to a discrimination depending on the ion mobility. This separation is observed, both in gaseous and liquid phase, by Ion Mobility Spectrometry (IMS), Capillary Electrophoresis (CE) and Liquid Chromatography (LC) which are hyphenated to mass spectrometry as detector. The separation efficiency of these ions by IMS and CE is improved by using specific shifting agents (18-Crown-6 Ether) selective to only one of these ions. This strategy has successfully separated the two isobaric ions present and leads to the structural elucidation of the isobar contaminant of SeMet. [less ▲]

Taking into account its non-invasive, non-destructive character and fast data acquisition, near infrared spectroscopy is more and more integrated in production processes to acquire analytical results. Implementation of a NIR quantitative method is performed using an iterative heuristic approach that will ultimately build a model allowing the prediction of the concentration of the analyte of interest. In this context, the aim of the present study was to develop an innovative approach based on statistical tolerance intervals and the desirability index FMI (Fitting Model Index) to select the most appropriate prediction model from a list of candidate models instead of using conventional criteria such as R², RMSEC, RMSECV and RMSEP [1-2] without objective decision rules. This new approach is illustrated on different steps of a real pharmaceutical manufacturing process: water and Active Pharmaceutical Ingredient (API) determinations in pharmaceutical pellets. Variability sources such as production campaigns, batches, days and operators were introduced in the calibration and validation sets. Partial Least Square (PLS) regression on the calibration sets was performed to build prediction models of which the ability to quantify accurately was tested with the validation sets. Regarding the product specifications, the acceptance limits were set at 20% and 5%, for the moisture and API determination, respectively.As can be seen from Figure 1 and 2, this innovative approach based on the desirability index FMI of the accuracy profile enabled to build and select the most appropriate prediction model in full accordance with its very final goal, to quantify as accurately as possible the analytes of interest.

A new innovative fog production device has been developed in close cooperation with partners of a European project called “FOG” funded by the EU. It is set up in the fog chamber of the road and bridges laboratory at Clermont-Ferrand. Most of the activities of this laboratory are dedicated to road safety but the facility is open to any other activity, such as environmental research. The recent developments consist in setting up a controllable device able to produce stable visibility levels and homogeneous fog, representative of various types of natural water droplet distribution. The fog characteristics were determined and compared to natural fog. Results are presented for a selection of conditions including stabilized visibility levels for dense fog, less than 50 metres meteorological visibility and two kinds of droplet distribution.

In the present paper, innovative joint configurations leading to more economical solutions for full-strength beam-to-column joints for seismic building frames are detailed. The specificities of these joints are due to the fact that (i) the column is made of high strength steel while the beam are made of mild carbon steel and (ii) the design of some components allows partially neglecting the overstrength factor. Also, methods for the characterisation of specific joint components not directly covered by the Eurocode recommendations are proposed. [less ▲]
