Sea-level response to melting of Antarctic ice shelves on multi-centennial timescales with the fast Elementary Thermomechanical Ice Sheet model (f.ETISh v1.0)
Authors: Pattyn Frank 
Published: August 2017

Abstract. The magnitude of the Antarctic ice sheet's contribution to global sea-level rise is dominated by the potential of its marine sectors to become unstable and collapse as a response to ocean (and atmospheric) forcing. This paper presents Antarctic sea-level response to sudden atmospheric and oceanic forcings on multi-centennial timescales with the newly developed fast Elementary Thermomechanical Ice Sheet (f.ETISh) model. The f.ETISh model is a vertically integrated hybrid ice sheet–ice shelf model with vertically integrated thermomechanical coupling, making the model two-dimensional. Its marine boundary is represented by two different flux conditions, coherent with power-law basal sliding and Coulomb basal friction. The model has been compared to existing benchmarks. Modelled Antarctic ice sheet response to forcing is dominated by sub-ice shelf melt and the sensitivity is highly dependent on basal conditions at the grounding line. Coulomb friction in the grounding-line transition zone leads to significantly higher mass loss in both West and East Antarctica on centennial timescales, leading to 1.5 m sea-level rise after 500 years for a limited melt scenario of 10 m a−1 under freely floating ice shelves, up to 6 m for a 50 m a−1 scenario. The higher sensitivity is attributed to higher ice fluxes at the grounding line due to vanishing effective pressure. Removing the ice shelves altogether results in a disintegration of the West Antarctic ice sheet and (partially) marine basins in East Antarctica. After 500 years, this leads to a 5 m and a 16 m sea-level rise for the power-law basal sliding and Coulomb friction conditions at the grounding line, respectively. The latter value agrees with simulations by DeConto and Pollard (2016) over a similar period (but with different forcing and including processes of hydrofracturing and cliff failure). The chosen parametrizations make model results largely independent of spatial resolution so that f.ETISh can potentially be integrated in large-scale Earth system models.

This study aims to identify the impact of electromagnetic waves at the full moon on some physiological changes among the students of the Faculty of Sport Sciences at Mu'tah University. The study sample consisted of 20 students from the Faculty of Sport Sciences at Mu'tah University. Many statistical methods have been used in order to answer the questions of the study (Means, standard deviations, T-Test Independent Samples, Pearson correlation coefficient. The results of (T-Test Independent Samples) for the significance of the pre and post difference showed that there are statistically significant differences for the variables of (heart pulse, blood glucose, systolic pressure and diastolic pressure). The results of Pearson correlation coefficient test for the pre and post measurement also showed that there are statistically significant differences for the physiological variable of (blood glucose) with regard to the variable of age. The study recommended not to rely on the reading of the heart pulse during the days of the full moon as an indicator of the heart pulse, especially for females. The study also recommends to conduct similar studies in different places of hot and cold climates or high and low altitudes .
Impact of Ownership Structure on Firm Performance in the MENA Region: An Empirical Study
Authors: Ahmed Neveen , Hadi Ola Abdel 
Published: August 2017

This paper investigates the impact of ownership structures on firm financial performance in the MENA region. The sample covers nine MENA countries (Egypt, Bahrain, Qatar, Kuwait, Tunisia, UAE, Morocco, Oman and Jordan) for the year 2014. We examine the impact of ownership structures on firm performance. Performance is proxied by Tobin-Q, ROE and ROA, while ownership structure is proxied using insider ownership, governmental, and blockholders. We control for risk, size, country effect and industry type. Our results suggest that blockholders, insider ownership and governmental ownership play a crucial role in firm performance measured by Tobin-Q, ROE and ROA respectively. Our results suggest that insider ownership negatively effects firm’s return on equity, while blockholder ownership has a positive impact on a firm’s Tobin-Q. Finally we find that governmental ownership plays a positive role on a firm’s return on assets in the MENA region.

Gerecht drukt Commissie met de neus op de feiten: de zaak Leidschendam
Gebiedsontwikkelingsprojecten roepen regelmatig staatssteunvragen op. De hier besproken zaak Leidschendam is daarvan een voorbeeld: een renovatieproject waarbij als gevolg van de crisis de afspraken tussen de gemeente en de ontwikkelaar zijn herzien. Volgens de Commissie was die herziening eenzijdig ten gunste van de ontwikkelaar. Begin 2013 vaardigde zij een verbodsbeschikking met terugvorderingsbevel uit. Op 30 juni 2015 oordeelde het Gerecht dat de Commissie onvoldoende zorgvuldig onderzoek had gedaan om te kunnen vaststellen dat de gemeente aan de ontwikkelaar staatssteun had verleend. Centraal in deze uitspraak staan de eisen die het Gerecht stelt aan de particuliere-investeerdertoets bij de herziening van een bouwproject.

Executieveilingen
Op 18 december 2014 oordeelde de Rechtbank Rotterdam over de gegrondheid en hoogte van de boetes opgelegd door ACM aan handelaren op executieveilingen. Deze handelaren hadden zich naar de mening van ACM in de periode 2000-2009 schuldig gemaakt aan overtredingen van het kartelverbod van artikel 6 lid 1 Mw. Volgens de rechtbank beschikte ACM over voldoende bewijs om de gedragingen te kunnen kwalificeren als één enkele inbreuk en de handelaren voor die enkele inbreuk aansprakelijk te houden. De rechtbank achtte een verlaging van de opgelegde boetes met 10 procent passend door de financiële gevolgen voor de handelaren van de ACM-besluiten.
Naar een vervanging van de unus-testisregel van artikel 342 lid 2 Sv
Authors: Nan Joost S. 
Published: August 2017

Towards a replacement of the unus testis rule of article 342 paragraph 2 of the Dutch Criminal Procedural Code
The rule that a conviction cannot be based on the statement of just one witness, is codified in article 342 of the Dutch Criminal Procedural Code. The Supreme Court has recently demanded that such a statement finds sufficient support in other evidence and that sometimes the trial judge needs to specify why that statement is corroborated enough by other evidence. However, the Supreme Court has always given a very marginal meaning to this rule, by allowing convictions which basically are substantiated by only that one statement. The evidence supporting the story of the witness does not have to prove that the crime actually took place, nor that is indeed the defendant who has committed it. In this article, I propose the replacement of the rule with a well-founded motivated ruling of the trial judge on this subject.

The discretion of the judge: A plea for more open and transparent demeanor
A fair trial can only be guaranteed if a judge gives as much insight in his line of thinking as possible and if a judge is actively participating in finding the truth in a criminal case. According to statutes and case law a judge has a lot of freedom to show how he feels about certain things during criminal proceedings. A challenge to a judge shall not quickly be admissible. Still, a judge needs to be impartial and willing to review his preliminary decision/opinion.

Criminal gangs or hardworking immigrants? The media discourse on Central and East Europeans in the Netherlands
The population of Central and East European immigrants in the Netherlands has increased following the eastward expansion of the European Union. Over the past years, a lot of media and political attention seems to focus on problems with crime and disorder relating to this immigrant group. This article describes a two-step study on this matter. First, by undertaking a media discourse analysis, we assess to what extent we can speak of a ‘hardened climate’ regarding Central and East Europeans in the Netherlands between 2007 and 2013. Second, we have conducted qualitative interviews with Central and East Europeans in the Netherlands, to explore their perceptions of the Dutch media and political discourse. The results show that this group is often connected with crime and disorder in the media, and that many of our respondents experience this negative framing. Dangers of this trend regarding feelings of discrimination, scapegoating, and self-fulfilling prophecies, are discussed.

AbstractThe area burned annually by wildfires is expected to increase worldwide due to climate change. Burned areas increase soil erosion rates within watersheds, which can increase sedimentation in downstream rivers and reservoirs. However, which watersheds will be impacted by future wildfires is largely unknown. Using an ensemble of climate, fire, and erosion models, we show that postfire sedimentation is projected to increase for nearly nine tenths of watersheds by >10% and for more than one third of watersheds by >100% by the 2041 to 2050 decade in the western USA. The projected increases are statistically significant for more than eight tenths of the watersheds. In the western USA, many human communities rely on water from rivers and reservoirs that originates in watersheds where sedimentation is projected to increase. Increased sedimentation could negatively impact water supply and quality for some communities, in addition to affecting stream channel stability and aquatic ecosystems.
Aftershocks driven by afterslip and fluid pressure sweeping through a fault‐fracture mesh

Published: August 2017

AbstractA variety of physical mechanisms are thought to be responsible for the triggering and spatiotemporal evolution of aftershocks. Here we analyze a vigorous aftershock sequence and postseismic geodetic strain that occurred in the Yuha Desert following the 2010 Mw 7.2 El Mayor‐Cucapah earthquake. About 155,000 detected aftershocks occurred in a network of orthogonal faults and exhibit features of two distinct mechanisms for aftershock triggering. The earliest aftershocks were likely driven by afterslip that spread away from the main shock with the logarithm of time. A later pulse of aftershocks swept again across the Yuha Desert with square root time dependence and swarm‐like behavior; together with local geological evidence for hydrothermalism, these features suggest that the events were driven by fluid diffusion. The observations illustrate how multiple driving mechanisms and the underlying fault structure jointly control the evolution of an aftershock sequence.
Effect of deformation on the thermal conductivity of granular porous media with rough grain surface

Published: August 2017

AbstractHeat transfer in granular porous media is an important phenomenon that is relevant to a wide variety of problems, including geothermal reservoirs and enhanced oil recovery by thermal methods. Resistance to flow of heat in the contact area between the grains strongly influences the effective thermal conductivity of such porous media. Extensive experiments have indicated that the roughness of the grains' surface follows self‐affine fractal stochastic functions, and thus, the contact resistance cannot be accounted for by models based on smooth surfaces. Despite the significance of rough contact area, the resistance has been accounted for by a fitting parameter in the models of heat transfer. In this Letter we report on a study of conduction in a packing of particles that contains a fluid of a given conductivity, with each grain having a rough self‐affine surface, and is under an external compressive pressure. The deformation of the contact area depends on the fractal dimension that characterizes the grains' rough surface, as well as their Young's modulus. Excellent qualitative agreement is obtained with experimental data. Deformation of granular porous media with grains that have rough self‐affine fractal surface is simulated. Thermal contact resistance between grains with rough surfaces is incorporated into the numerical simulation of heat conduction under compressive pressure. By increasing compressive pressure, thermal conductivity is enhanced more in the grains with smoother surfaces and lower Young's modulus. Excellent qualitative agreement is obtained with the experimental data.

Beam focal spot position: The forgotten linac QA parameter. An EPID‐based phantomless method for routine Stereotactic linac QA
Authors: Chojnowski Jacek M. , Barnes Michael P. , Sykes Jonathan R. , Thwaites David I. 
Published: August 2017

AbstractModern day Stereotactic treatments require high geometric accuracy of the delivered treatment. To achieve the required accuracy the IGRT imaging isocenter needs to closely coincide with the treatment beam isocenter. An influence on this isocenter coincidence and on the spatial positioning of the beam itself is the alignment of the treatment beam focal spot with collimator rotation axis. The positioning of the focal spot is dependent on the linac beam steering and on the stability of the monitor chamber and beam steering servo system. As such, there is the potential for focal spot misalignment and this should be checked on a regular basis. Traditional methods for measuring focal spot position are either indirect, inaccurate, or time consuming and hence impractical for routine use. In this study a novel, phantomless method has been developed using the EPID (Electronic Portal Imaging Device) that utilizes the different heights of the MLC and jaws. The method has been performed on four linear accelerators and benchmarked against an alternate ion chamber‐based method. The method has been found to be reproducible to within ±0.012 mm (1 SD) and in agreement with the ion chamber‐based method to within 0.001 ± 0.015 mm (1 SD). The method could easily be incorporated into a departmental routine linac QA (Quality Assurance) program.

AbstractThe purpose of this study is to identify regions of spinal column in which more than three contiguous vertebrae can be reliably and quickly aligned within 1 mm using a 6‐degree (6D) couch and full body immobilization device. We analyzed 45 cases treated over a 3‐month period. Each case was aligned using ExacTrac x‐ray positioning system with integrated 6D couch to be within 1° and 1 mm in all six dimensions. Cone‐Beam computed tomography (CBCT) with at least 17.5 cm field of view (FOV) in the superior–inferior direction was taken immediately after ExacTrac positioning. It was used to examine the residual error of five to nine contiguous vertebrae visible in the FOV. The residual error of each vertebra was determined by expanding/contracting the vertebrae contour with a margin in millimeter integrals on the planning CT such that the new contours would enclose the corresponding vertebrae contour on CBCT. Submillimeter initial setup accuracy was consistently achieved in 98% (40/41) cases for a span of five or more vertebrae starting from T2 vertebra and extending caudally to S5. The curvature of spinal column along the cervical region and cervicothoracic junction was not easily reproducible between treatment and simulation. Fifty‐seven percent (8/14) of cases in this region had residual setup error of more than 1 mm in nearby vertebrae after alignment using 6D couch with image guidance. In conclusion, 6D couch integrated with image guidance is convenient and accurately corrects small rotational shifts. Consequently, more than three contiguous vertebrae can be aligned within 1 mm with immobilization that reliably reproduces the curvature of the thoracic and lumbar spinal column. Ability of accurate setup is becoming less a concern in limiting the use of stereotactic radiosurgery or stereotactic body radiation therapy to treat multilevel spinal target.
