We study a pair trading strategy that utilizes short-term return reversals in the stock market. Using U.S. data, we show that returns to our pair trading strategy exceed reasonable estimates for transaction costs. The strategy also generates positive alpha when controlling for the standard risk factors. Second, using transaction level data from Finland, focusing on a popular pair, we provide evidence that these kinds of pair trading returns are compensation from providing liquidity. On the days when the expected returns to our pair trading strategy are the highest, the trading volume is abnormally high and, judging from active brokers’ net trades, nearly 45% of all brokers (or their customers) engage in pair trading in accordance with our trading strategy. These brokers are mainly counterparties to few brokers that trade large quantities of stocks inconsistent with our strategy. [less ▲]

The European Union is a union under the rule of law and accordingly all exercise of public authority needs to conform with the principle of legality. The legal framework of the EU is, however, as much as that of any state or international organization, subject to change over time. That part of this legal framework specifically governing EU administration has been particularly dynamic. The central reason for this dynamism is to be found in the evolving nature of European integration, and in the changing requirements and conditions for implementing EU policies. The legal framework of administration has been both the subject of, and a response to, change in the ambient political and institutional environment. The EU, having started as an organization of six Member States focused on economic integration, has evolved into a Union of twenty-seven Member States now touching almost all elements of the exercise of public power in a modern society. The evolutionary development of the constitutional basis of EU law, with its many phases of Treaty reforms and change induced by case-law, finds its parallel in EU administrative law. European administrative law has in this process grown, changed, and indeed matured over time, and has emerged as an important, yet sometimes not well understood, factor which materially shapes policy in the EU and its achievement in reality. The rise of the importance of EU administrative law is itself attributable both to the specificities of European integration and to the general increase in the importance of administrative regulation in the past decades. On the one hand, the protection of the society against risks associated with private activity such as banking, food production, energy production and distribution, transport, or activities threatening to the environment, to name just a few, and the achievement of a balance between their benefits and dangers have become increasingly important subjects of attention. On the other hand, the provision of services and infrastructure necessary to ensure and protect basic standards of living such as pensions, health care, access to water, energy supply and telecommunications services have been the subject of mixed regimes, often still having a strong public service element, but increasingly left to private provision subject to various levels of market regulation. Both kinds of motivation for regulatory measures and their implementation by appropriate authorities have added to, and substantially changed, the broad character of public administration in Europe in recent decades. Such changes have occurred not just on a national, that is, Member State level, but also, pre-eminently, on the level of the European Community and now Union. Indeed, many of the changes have themselves been triggered on the European level as integral or at least adjuvant elements of the establishment of the European internal market. The role, then, of administrative law and administrative activity on the European level is extensive and important. Rules and principles governing the exercise of administrative functions, the organization of the institutions and bodies exercising these functions, and applicable procedures are the essence of EU administrative law. These are the subject of this book. There are, it must be observed, many perspectives from which one can view, analyse and comprehend both administration and administrative law. Three models or perspectives appear to us to be particularly helpful: administration and administrative law may be usefully considered from functional, organizational, and procedural standpoints. The functional aspect of administration refers to the totality of the tasks of administration, no matter who undertakes them and how they are carried out. The organizational perspective emphasises the organization and structure of the institutions, bodies, and actors engaged in undertaking such tasks. Finally, a procedural understanding of administration observes the processes which link the various actors and authorities in the performance of administrative functions. None of these models standing alone provides a fully rounded understanding or conceptualisation of the subject matter of the book. A proper analysis of EU administrative law cannot view it from only one of these perspectives. Taken together, however, these three standpoints do offer a comprehensive perception, giving the subject a more multi-dimensional shape, and thus allowing a more tractable presentation of what is very complex material. For this reason, we offer a discussion of each of these three perspectives — the functional, organizational, and procedural aspects of European Union administration and the associated legal framework — by way of introduction. The three models are, of course, closely interlinked and in reality scarcely separable but, for analytical and presentational clarity, they are here addressed separately. [less ▲]

This chapter contrasts two different views on ageing. An external “view from without” starts in a first step with the description of phenomena associated with human ageing including the notions of death and dying. This is followed by presenting an overview of central and mostly psychological models and theories about human ageing. Here, life span conceptions as well as theories on self-regulation of the ageing self are described and discussed. Furthermore, a specific focus is put on the differing qualifications that the term ageing has received in diverse theoretical models. The internal “view from within” finally starts with three case stories presenting excerpts of individual biographic narratives that highlight the importance of life events and adaptive processes within the family in the subjective construction of the self and the life course. The conclusion elaborates a person-centred approach in the study of human ageing taking into account that both family and culture interact in forming development in general as well as life in advancing age in particular.

Description Logics (DLs) under Rational Closure (RC) is a well-known framework for non-monotonic reasoning in DLs. In this paper, we address the concept subsumption decision problem under RC for nominal safe $ELO_{\bot}$, a notable and practically important DL representative of the OWL 2 profile OWL 2 EL. Our contribution here is to define a polynomial time subsumption procedure for nominal safe $ELO_{\bot}$ under RC that relies entirely on a series of classical, monotonic $EL_{\bot}$ subsumption tests. Therefore, any existing classical monotonic $EL_{\bot}$ reasoner can be used as a black box to implement our method. We then also adapt the method to one of the known extensions of RC for DLs, namely Defeasible Inheritance-based DLs without losing the computational tractability. [less ▲]

Annotated Legal Documents on Islam in Luxembourg consist of an annotated book of currently valid legal documents affecting the status of Islam and Muslims in Luxembourg. By legal documents are meant the texts of legislation, including relevant secondary legislation, as well as significant court decisions. Each legal text will be preceded by an introduction describing the historical, political and legal circumstances of its adoption, plus a short paragraph summarising its content. The legal texts will be published in the original language while the annotations and supporting material will be in English. The focus of the book is on the religious dimensions of being Muslim in Luxembourg, i.e. on individuals' access to practise their religious obligations and on the ability to organise and manifest their religious life. It's a part of a project will cover the 28 member states of the European Union (including Croatia), Norway and Switzerland plus the European Union and the European Court of Justice. [less ▲]

This paper proves the practicality of an iterative algorithm for solving realistic large-scale SCOPF problems. This algorithm is based on the combination of a contingency filtering scheme, used to identify the binding contingencies at the optimum, and a network compression method, used to reduce the complexity of the post-contingency models included in the SCOPF formulation. We show that by combining these two complementary ideas, it is possible to solve in a reasonable time SCOPF problems on large power system models with a large number of contingencies. Unlike most results reported for large-scale SCOPF problems, our algorithm uses a non-linear AC network model in both pre-contingency and post-contingency states, optimizes both active/reactive powers flows jointly, and treats the discrete variables. The proposed algorithm is implemented with state-of-the-art solvers and applied to two systems: a national grid with 2563 buses and 1297 contingencies, and a model of the European transmission network with 9241 buses and 12000 contingencies.
