Our objective in this paper is to examine whether one can use option-implied information to improve the selection of mean-variance portfolios with a large number of stocks, and to document which aspects of option-implied information are most useful to improve their out-of-sample performance. Portfolio performance is measured in terms of volatility, Sharpe ratio, and turnover. Our empirical evidence shows that using option-implied volatility helps to reduce portfolio volatility. Using option-implied correlation does not improve any of the metrics. Using option-implied volatility, risk premium, and skewness to adjust expected returns leads to a substantial improvement in the Sharpe ratio, even after prohibiting short sales and accounting for transaction costs.

The paper deals with the transition to Higher Education focusing on educational inequalities at the intersection of gender and migrant background. At the core of the analyses, theorized referring to decision theory, is a comparison of Switzerland (TREE), Germany (HIS-Studienberechtigte 2002) and France (Panel d’élèves du second degré 1995). Results indicate increased transition rates to Higher Education for second-generation males from some socially disadvantaged migrant groups for Switzerland and Germany, if controlled for social origin. Evidence confirming a female disadvantage for second generation females originating from countries characterised by a rather patriarchal culture were not found in any of the countries under consideration.

This paper presents the development of a control model for inverter driven island grids. The herein presented structured approach creates a multi voltage source inverter model from a single inverter state space model and combines this with the node incidence matrix of a network into a compound model of an island grid. The presented approach allows to analyse arbitrary grid structures and different inverter models and it incorporates a large number of inverters. The model can be particularly used for ohmic-inductive low voltage lines. At the end of the article, a stability analysis of a sample network is presented. [less ▲]

We study numerically the linear second order wave equation with an output quantity of interest which is a linear functional of the field variable using reduced basis approximation methods in the space-time domain. The essential new ingredient is the a posteriori error estimation of the output quantity of interest. The technique, which is based on the well-known dual-weighted residual (DWR) method is deployed within a reduced basis approximation context. First, we introduce the reduced basis recipe - Galerkin projection onto a space spanned by the reduced basis functions which are constructed from the solutions of the governing PDE at several selected points in the parameter space. Second, in order to construct these basis functions we propose a new “goal-oriented” Proper Orthogonal Decomposition (POD)-Greedy sampling procedure, which is based on these new a posteriori error estimations. Finally, this a posteriori error estimation is also used to evaluate approximately the quality of many output computations in the online stage within the reduced basis procedure. [less ▲]

Recently it has been shown that it is possible to derive time-variable gravity signals from high-low satellite-to-satellite tracking (hl-SST) missions (Weigelt et al. 2013, JGR:Solid Earth, doi:10.1002/jgrb.50283). Based on the GPS information only, we will present results derived from the dedicated gravity field missions CHAMP, GRACE and GOCE which allow us to determine mass estimates for various applications. Hydrologically induced mass changes on land cause the strongest mass variations in the gravity field and can be easily identified in the hl-SST data, especially in areas with strong signals such as the Amazon basin. Ice melt in Greenland can be derived from the data and mass estimates compare well to corresponding GRACE estimates. Also, loading time series based on these gravity field solutions agree well with GPS observations for various stations around the globe. We also discuss the limitations of the data, e.g. in detecting signals related to glacial isostatic adjustment or earthquake-induced gravity field changes. Overall, we will demonstrate that the quality of the GPS data is sufficient nowadays and with a proper processing strategy it is possible to derive reasonable mass estimates. As such, this type of observations may allow to bridge a possible gap between GRACE and its successor GRACE Follow-On scheduled for launch in 2017. [less ▲]

The doctrine of accessory allocation is given special significance as a connecting factor by the framers of Rome I Regulation (through Recitals 20 and 21) in utilising the escape clause and principle of closest connection under Article 4. This article analyses the application of the doctrine under the Rome Convention; the possible reasons why the framers of Rome I gave the doctrine special significance; the nature of inquiry a Member State court would be faced with in applying the doctrine especially in very closely related contracts such as back-to-back contracts; and the dilemma faced by the court in determining the quantum of weight to attach to the application of the doctrine as it relates to displacing the main rule(s). The author concludes by stating that there is need for more clarity on the significance of the doctrine of accessory allocation as a connecting factor under Article 4 of Rome I. [less ▲]

To face continuously growing security threats and requirements, sound methodologies for constructing secure systems are required. In this context, Model-Driven Security (MDS) has emerged since more than a decade ago as a specialized Model-Driven Engineering approach for supporting the development of secure systems. MDS aims at improving the productivity of the development process and quality of the resulting secure systems, with models as the main artifact. This paper presents how we systematically examined existing published work in MDS and its results. The systematic review process, which is based on a formally designed review protocol, allowed us to identify, classify, and evaluate different MDS approaches. To be more specific, from thousands of relevant papers found, a final set of the most relevant MDS publications has been identified, strictly selected, and reviewed. We present a taxonomy for MDS, which is used to synthesize data in order to classify and evaluate the selected MDS approaches. The results draw a wide picture of existing MDS research showing the current status of the key aspects in MDS as well as the identified most relevant MDS approaches.We discuss the main limitations of the existing MDS approaches and suggest some potential research directions based on these insights.

The detection reliability of a cognitive radio network improves by employing a cooperative spectrum sensing scheme. However, increasing the number of cognitive radios entails a growth in the cooperation overhead of the system. Such an overhead leads to a throughput degradation of the cognitive radio network. Since current cognitive radio networks consist of low-power radios, the energy consumption is another critical issue. In this paper, throughput optimization of the hard fusion based sensing using the k-out-of-N rule is considered. We maximize the throughput of the cognitive radio network subject to a constraint on the probability of detection and energy consumption per cognitive radio in order to derive the optimal number of users, the optimal k and the best probability of false alarm. The simulation results based on the IEEE 802.15.4/ZigBee standard, show that the majority rule is either optimal or almost optimal in terms of the network throughput. [less ▲]

This book’s main focus is the “cultural” aspects of being and becoming a Filipino feminist. It sets out to articulate the “political” within the feminist agenda. The book, importantly, raises the question “What is ‘Filipino’ feminism today?” Roces answers this question by highlighting three significant forces that have shaped its history, including the postcolonial condition, the national democratic struggle and western feminism, and the ways in which these forces intersect with the “Filipino feminist agenda”.
