Unemployment in an Estimated New Keynesian Model
No full textWe reformulate the Smets-Wouters (2007) framework by embedding the theory of unemployment proposed in Galí (2011a,b). We estimate the resulting model using postwar U.S. data, while treating the unemployment rate as an additional observable variable. Our approach overcomes the lack of identification of wage markup and labor supply shocks highlighted by Chari, Kehoe and McGrattan (2008) in their criticism of New Keynesian models, and allows us to estimate a "correct" measure of the output gap. In addition, the estimated model can be used to analyze the sources of unemployment fluctuations.nominal rigidities, unemployment fluctuations, Phillips curve, wage markups shocks, output gap.

Desdemona and a ticket to space; training for space flight in a 3g motion simulator
No full textOn October 5, 2013, Marijn Wouters and two other contestants of a nation-wide competition ‘Nederland Innoveert’ underwent a space training exercise. One by one, the trainees were pushed to their limits in the Desdemona motion simulator, an experience that mimicked the Space Expedition Corporation (SXC) space flight envelope. The ultimate goal: training for an actual mission, the 1st prize in the aforementioned competition.Aerospace Engineerin
MDPs, Spinning, and Wouters v. NOVA
No full textThis article is one of a series of articles by Professor Laurel Terry regarding the topic of MDPs of multidisciplinary partnerships. In February 2002, the European Court of Justice issued its opinion in Wouters v. NOVA (Case C-309/99), which addressed a Netherlands Bar rule that prohibited multidisciplinary partnerships (MDPs) between lawyers and accountants. Wouters decided: 1) that the bar was an “undertaking” that was subject to the competition (antitrust) provision in the EU Treaty; 2) that the Dutch MDP ban restricted competition and that this restriction on competition was appreciable and affected intra-community trade; 3) that the Dutch MDP ban could “reasonably be considered necessary in order to ensure the proper practice of the legal profession”; and 4) that it was reasonable for the Dutch Bar to conclude that its objectives could not “be attained by less restrictive means.”
This article, which was written two weeks after the Wouters decision for an MDP Symposium, contends that the Wouters case is extremely significant for the European legal profession. After summarizing the facts of Wouters v. NOVA case, which the author first addressed in Laurel S. Terry & Clasina B. Houtman Mahoney, What If . . . ? The Consequences of Court Invalidation of Lawyer_Accountant Multidisciplinary Partnership Bans in Private Investments Abroad_Problems & Solutions in International Business in 1998, Chap. 7 (Matthew Bender 1999), this article continues by noting that much of the publicity connected with the Wouters case has focused on the rulings about MDPS. This publicity has focused on the blow Wouters gave to the MDP movement. This article contends that the more significant rulings are the first two rulings noted above. These rulings are extremely important because they articulate significant conditions to bars’ abilities to regulate lawyers. The article also argues that bars should not expect to have all decision-makers in the future act as this European Court of Justice did in deferring so completely to the bars’ judgment about whether a rule is necessary and whether an objective could be attained by less restrictive means

Molecular Beam Epitaxy of β-(InxGa1–x)2O3 on β-Ga2O3 (010): Compositional Control, Layer Quality, Anisotropic Strain Relaxation, and Prospects for Two-Dimensional Electron Gas Confinement
No full textIn this work, we investigate the growth of monoclinic β-(InxGa1–x)2O3 alloys on top of (010) β-Ga2O3 substrates via plasma-assisted molecular beam epitaxy. In particular, using different in situ (reflection high-energy electron diffraction) and ex situ (atomic force microscopy, X-ray diffraction, time-of-flight secondary ion mass spectrometry, and transmission electron microscopy) characterization techniques, we discuss (i) the growth parameters that allow for In incorporation and (ii) the obtainable structural quality of the deposited layers as a function of the alloy composition. In particular, we give experimental evidence of the possibility of coherently growing (010) β-(InxGa1–x)2O3 layers on β-Ga2O3 with good structural quality for x up to ≈ 0.1. Moreover, we show that the monoclinic structure of the underlying (010) β-Ga2O3 substrate can be preserved in the β-(InxGa1–x)2O3 layers for wider concentrations of In (x ≤ 0.19). Nonetheless, the formation of a large amount of structural defects, like unexpected (10-2) oriented twin domains and partial segregation of In is suggested for x > 0.1. Strain relaxes anisotropically, maintaining an elastically strained unit cell along the a* direction vs plastic relaxation along the c* direction. This study provides important guidelines for the low-end side tunability of the energy bandgap of β-Ga2O3-based alloys and provides an estimate of its potential in increasing the confined carrier concentration of two-dimensional electron gases in β-(InxGa1–x)2O3/(AlyGa1–y)2O3 heterostructures
On the use of Biplot analysis for multivariate bibliometric and scientific indicators
No full textBibliometric mapping and visualization techniques represent one of the main pillars in the field of scientometrics. Traditionally, the main methodologies employed for representing data are Multi-Dimensional Scaling, Principal Component Analysis or Correspondence Analysis. In this paper we aim at presenting a visualization methodology known as Biplot analysis for representing bibliometric and science and technology indicators. A Biplot is a graphical representation of multivariate data, where the elements of a data matrix are represented according to dots and vectors associated with the rows and columns of the matrix. In this paper we explore the possibilities of applying the Biplot analysis in the research policy area. More specifically we will first describe and introduce the reader to this methodology and secondly, we will analyze its strengths and weaknesses through three different study cases: countries, universities and scientific fields. For this, we use a Biplot analysis known as JK-Biplot. Finally we compare the Biplot representation with other multivariate analysis techniques. We conclude that Biplot analysis could be a useful technique in scientometrics when studying multivariate data and an easy-to-read tool for research decision makers
Interaction between stroke severity and quality indicators of acute stroke care : a single-center retrospective analysis
No full textIschemic stroke leads to substantial mortality and morbidity worldwide. Door-to-CT time, door-to-needle time (DNT), and door-to-groin time (DGT) are important quality indicators of stroke care. However, patient characteristics remain important determinants of outcome as well. In this single-center study, we investigated the interaction between these quality indicators and stroke severity regarding long-term functional outcome. All consecutive stroke patients treated at the ZOL stroke center, Genk, Belgium, between 2017 and 2020 were included in this retrospective observational study. Stroke severity was graded as "mild" if National Institutes of Health Stroke Scale (NIHSS) was equal to or lower than 8, "moderate" if NIHSS was between 9 and 15, and "severe" if NIHSS was higher than 16. Modified Rankin Scale (mRS) scores were collected before and 3 months after stroke. Ordinal regression analysis with correction for patient characteristics of functional outcome was done. A total of 1255 patients were included, of which 84% suffered an ischemic CVA (n = 1052) and 16% a TIA (n = 203). The proportion of patients treated conservatively or with thrombolysis, thrombectomy, or the combination of both differed according to stroke severity (p < 0.0001). Door-to-CT time was longer in mild and moderate stroke (p < 0.0001). Median DNT also differed between stroke categories: 46 (IQR 31-70) min for mild vs. 36 (25-56) min for moderate vs. 30 (21-45) min for severe stroke (p = 0.0002). Median DGT did not differ between stroke severity categories (p = 0.15). NIHSS on admission and pre-stroke mRS were independently associated with mRS at 90 days. Operational performance, reflected in door-to-CT time and DNT, was worse in patients with mild and moderate stroke severity. DNT was also associated with functional outcome in our center, along with pre-stroke mRS, NIHSS on admission and age
