[more ▼]Traditional real options models regard the idiosyncratic risk of a project as the main value driver. Beyond the specific risks embedded in the project, i.e., both its technical and idiosyncratic risk, our model captures the interactions among different market, economic and social forces and their impact on R&D project valuation. Using Fourier series, our model aggregates external forces that play relevant roles in the process that determines the cash flow structure. Consequently, the posited model provides managers and policy makers with a powerful yet flexible tool to stress test several economic scenarios under which the project could develop. In a practical case, we apply our novel model and methodology to the valuation of a pharmaceutical R&D project and examine the impact of external forces on the optimal time to launch the project. The real options approach also allows for the possibility of optimally abandoning a project before completion whenever the investment cost exceeds the expected net cash flow stream after considering the impact of market conditions.

[more ▼]From a survival analysis perspective, since defaults are rare events, bank failures data often exhibit heavy censoring rate. This empirical evidence can be explained by the existence of a subpopulation of banks likely immune from bankruptcy. In this regard, we use a mixture cure model to separate the factors with an influence on the susceptibility to default from the ones affecting the survival time of susceptible banks. In this paper, we extend a semi-parametric proportional hazards cure model to time-varying covariates and we propose a variable selection technique based on its penalized likelihood. By means of a simulation study, we show how this technique per- forms reasonably well. Finally, we illustrate an application to commercial bank failures in the United States over the period 2006-2016.

It is based on a double analysis : - firstly on a statement of objective insecurity identified in the station and its surroundings by the police between 2007 and 2015 ; - secondly on a survey on the feeling of insecurity (subjective insecurity) conducted in 2015 by the operator of the station (SNCB – Belgian National Railway Company).

[more ▼]Any imbalance between electric power supply and demand results in power system frequency deviations from its nominal value. Frequency regulation is one of the most important services that regional system operators perform to ensure reliable system operation. Traditional power supply sources such as generators are usually automatically modulated to help balance generation and demand by adjusting their output based in part on system frequency. As a result of the decreased inertia of the system caused by decommissioning of traditional power plants and the increase in the penetration of renewable energy sources, the increased use of demand side controls for the purpose of frequency regulation is receiving increased attention. Demand control can provide fast response to any imbalance. This opens up the possibility for Electric Vehicles (EVs) to be used as frequency regulation grid resources. This write-up discusses the potential, opportunities and benefit of doing so.

[more ▼]In the era that huge numbers of microbial genomes are being released in the databases, it becomes increasingly important to rapidly mine genes as well as predict the regulatory networks that control their expression. To this end, we have developed an improved and online version of the PREDetector software aimed at identifying putative transcription factor-binding sites (TFBS) in bacterial genomes. The original philosophy of PREDetector 1.0 is maintained, i.e. to allow users to freely fix the DNA-motif screening parameters, and to provide a statistical means to estimate the reliability of the prediction output. This new version offers an interactive table as well as graphics to dynamically alter the main screening parameters with automatic update of the list of identified putative TFBS. PREDetector 2.0 also has the following additional options: (i) access to genome sequences from different databases, (ii) access to weight matrices from public repositories, (iii) visualization of the predicted hits in their genomic context, (iv) grouping of hits identified in the same upstream region, (v) possibility to store the performed jobs, and (vi) automated export of the results in various formats. PREDetector 2.0 is available at http://predetector.fsc.ulg.ac.be/.

[more ▼]The recent publication of the report "Medical error-the third leading causes of death in the US" (Makary & Daniel, 2016) has led to a renewed attention to the issue of patient safety in many developed countries. The main issue involved is the role played by medical staff work in the occurrence of deaths from the medical care. According to Makary & Daniel, communication failures, misdiagnosis, bad judgments and inadequate skills have caused an average of 251,454 deaths per year in the United States in 2013. This report has taken the opposite view of the proponents of "No shame no blame" approach characterizing a non-punitive culture in which people are led to blame the system even though human responsibility is obvious. While the no-blame culture has often been presented as the success factor of an efficient safety /quality policy in medical settings (Amalberti et al., 2005; Woynar et al, 2007), discordant voices now stand to underline the limits of this approach (see eg Dekker & Breakey, 2016; Levitt, 2014 or Shojania & Dixon-Woods, 2013). These authors argue that the no-blame culture is difficult to implement in practice and suggest the implementation of a just culture that places more emphasis on individuals' behavior and performance and on their responsibility at work. In this context, this study examines – based on an in-depth longitudinal case study of a radiotherapy department that has implemented a reporting system for adverse events - the extent to which non-punitive culture and just culture can live together in the same organizational unit. By combining in-depth interviews with members of the quality team and a questionnaire survey administered to all staff, we evaluate the current safety subcultures in the service. The content analysis of the interviews and the treatment of questionnaires following the methodology of the Agency for Healthcare Research and Quality allows to see the emergence of three subcultures in the radiotherapy department studied: a reporting subculture, a non-punitive subculture and, to some extent, a just subculture. The study shows that the development of the safety culture in this department is based primarily on the establishment of a non-punitive subculture used as a way to encourage spontaneous reporting of adverse events. The reporting culture is therefore the more controlled dimension of the safety culture of the department. Concerning responsibility of workers, the study shows that they have no fear of punishment and are not even familiar with the term in the workplace. On the contrary, instead of a retributive just culture, the department has focused its safety culture on learning from mistakes and substantial just culture based on a system of worker participation in the preparation of procedures that prescribe the right way to work.

[more ▼]We present a summary of important computational issues and opportunities that arise from the use of semi-aggregate data (where the explanatory data for choice scenarios are not necessarily unique for each decision-maker) in discrete choice models. This data feature is commonly encountered with large transactional databases that have limited consumer information, such as itinerary choice modeling. We developed a software package called Larch, written in Python and C++, to take advantage of this kind of data to greatly speed the estimation of discrete choice model parameters. Benchmarking experiments against Stata (a commonly used commercial package) and Biogeme (a commonly used freeware package) based on an industry dataset for airline itinerary choice modeling applications shows that the size of the input estimation files are 50 to 100 times larger in Stata and Biogeme, respectively. Estimation times are also much faster in Larch; e.g., for a small itinerary choice problem, a multinomial logit model estimated in Larch converged in less than one second whereas the same model took almost 15 seconds in Stata and more than three minutes in Biogeme. For more complex discrete choice models, such as the ordered generalized extreme value model, estimation times were two seconds in Larch and four to five days in Biogeme.

We then apply the bootstrap method to adjust the control charts’ limits to guarantee the desired in-control average run length (ARL0) value in monitoring stage. The adjusted limits ensure that ARL0 would take a value greater than the desired value (say, B) with a certain specified probability, that is Pr⁡(ARL_0>B)=1-ρ. We finally provide users with tables which with practitioners do not need to do bootstrapping Phase I data set to obtain the control limit thresholds.

[more ▼]We report the discovery of two transiting planetary systems: a super dense, sub-Jupiter mass planet WASP-86b (\mpl\ = 0.82 $\pm$ 0.06 \mj, \rpl\ = 0.63 $\pm$ 0.01 \rj), and a bloated, Saturn-like planet WASP-102b (\mpl\ = 0.62 $\pm$ 0.04 \mj, \rpl\=1.27 $\pm$ 0.03 \rj). They orbit their host star every $\sim$5.03, and $\sim$2.71 days, respectively. The planet hosting WASP-86 is a F7 star (\teff\ = 6330$\pm$110 K, \feh\ = $+$0.23 $\pm$ 0.14 dex, and age $\sim$0.8--1~Gyr), WASP-102 is a G0 star (\teff\ = 5940$\pm$140 K, \feh\ = $-$0.09$\pm$ 0.19 dex, and age $\sim$1~Gyr). These two systems highlight the diversity of planetary radii over similar masses for giant planets with masses between Saturn and Jupiter. WASP-102b shows a larger than model-predicted radius, indicating that the planet is receiving a strong incident flux which contributes to the inflation of its radius. On the other hand, with a density of $\rho_{pl}$ = 3.24$\pm$~0.3~$\rho_{jup}$, WASP-86b is the densest gas giant planet among planets with masses in the range 0.05 \$
