Abstract: Using a novel dataset from the 2006 Portuguese Labor Force Survey this paper examines the impact of a voluntary reduction in hours of work, before retirement, on the moment of exit from the labor force. If, as often suggested, flexibility in hours of work is a useful measure to postpone retirement, then a reduction in working hours should be associated with retirement at later ages. Results prove otherwise suggesting that reducing hours of work before retirement is associated with early exits from the labor force.

In a variety of applications ranging from environmental and health sciences to bioinformatics, it is essential that data collected in large databases are generated stochastically. This states qualitatively new problems both for statistics and for computer science. Namely, instead of deterministic (usually worst case) analysis, the average case analysis is needed for many standard database problems. Since both stochastic and deterministic methods and notation are used it causes additional dif®culties for an investigation of such problems and for an exposition of results. We consider a general class of probabilistic models for databases and study a few problems in a probabilistic framework. In order to demonstrate the general approach, the problems for systems of database constraints (keys, functional dependencies and related) are investigated in more detail. Our approach is based on consequent using Re Ânyi entropy as a main characteristic of uncertainty of distribution and Poisson approximation (Stein±Chen technique) of the corresponding probabilities. several attributes) that uniquely identi®es a particular record in a set of records. If multisets (or tables, i.e., collections of elements with possibly coinciding values) are considered then a key identi®es the record within the multi-set. The set of all attributes, thus, forms a key in a set of records as well as in a multi-set of records. But, smaller sets of attributes that can be used to identify records as far as possible are of interest. A given set of attributes is a minimal key if its proper subsets are not keys. Keys are generalized to functional dependencies which specify relationships between two disjoint attribute sets. In a database, the values of the ®rst set determine the values of the second set. The exact de®nitions will be given further in this section. Various types of keys and functional dependencies constitute constraints in a database. If a database designer knows the complete set of constraints in a given application then unpredictable behavior during modi®cation of the database can be avoided. Therefore, the size of constraint set is of great interest. If this size is exponential in the number of attributes then the entire approach becomes unmanageable (see, e.g., Mannila and Ra Èiha È, 1994;. Knowledge of a constraint set allows users also to avoid redundancy and to optimize database design in many time and space consuming problems (e.g., searching and sorting, geological forecasting, diagnosis in medicine and in digital circuits). In a random database (also referred to as statistical database), tuples are random vectors with a common discrete distribution. Up until recently the problem of characterization of the most relevant properties for some constraints has been mainly addressed in the worst case setting (see, e.g., Mannila and Ra Èiha È, 1992; Thalheim, 1991 Thalheim, , 2000. Then the combinatorial approach is feasible for a given class of databases. But this approach is restrictive both for the class of models and for possible applications since the worst event is very unlikely in practice. Moreover, a discrepancy between mathematical results and computational experience of practitioners increases. In this paper, we aim this problem in average case setting (cf. average complexity setting in scienti®c computing, Traub et al., 1988; Szpankowski, 2001) for a general class of probabilistic models. In particular, we establish where the distribution of keys and minimal keys concentrates (i.e., typical keys), and for which model parameters. Speci®cally, an entropy of a tuple distribution determines the key properties of sets of attributes. Informally, a less varying distribution of attributes values causes less keys in a database in average.

Such communities define themselves as separate peoples, with different and often competing interests, yet their interaction is usually peaceable provided the dominance of one group is clear. The key indicator of dominance is control over central religious sites, which may be tacitly shared for long periods, but later contested and even converted as dominance changes. By focusing on these shared and contested sites, this volume allows for a wider understanding of relations between these communities. Using a range of ethnographic, historical and archaeological data from the Balkans, India, Mexico, Peru, Portugal and Turkey, Antagonistic Tolerance develops a comparative model of the competitive sharing and transformation of religious sites. These studies are not considered as isolated cases, but are instead woven into a unified analytical framework which explains how long-term peaceful interactions between religious communities can turn conflictual and even result in ethnic cleansing. This book marks the culmination of the Antagonistic Tolerance project, in which a multidisciplinary and international research team developed a comparative framework for the analysis of competitive sharing of religious sites, in religioscapes, or networks of other such sites. Robert M. Hayden was Senior author; co-authors were Tuğba Tanyeri-Erdemir, Timothy D. Walker, Aykan Erdemir, Devika Rangachari, Manuel Aguilar-Moreno, Enrique López-Hurtado, and Milica Bakić-Hayden. The works draws on ethnographic, archaeological, historical and architectural data from Anatolia, the Balkans, India, Mexico, Peru, and Portugal.
