Initial Career and Work Meanings in Seven European Countries

This study explores the initial careers of two target groups of young adults in seven European countries. Career patterns have been constructed through cluster analysis on data gathered from the young adults through a retrospective self-report procedure covering a period of 2.5 years. Six career patterns have been identified across countries by the activities taking place (employment, various educational preparations, unemployment, military or civil service) and have been further described by personal and work-related variables as well as by meaning of work indices (work centrality, intrinsic versus extrinsic work orientations, and societal norms about working) and psychological well-being in the second year on the labor market. Suggestions for further research as well as the implications for career counseling, career education, organizational career guidance and development have been given.     

Positional independence in preference aggregation

If, for strict preferences, a unique choice function (CF) is used to aggregate preferences position-wise then the resulting social welfare function (SWF) is dictatorial. This suggests that the task performed by non-dictatorial SWFs must be “more complex” than just selecting an alternative from a list using a single criterion. This is because the information required by non-dictatorial SWFs to aggregate preferences cannot be compressed into a CF. It is also shown that the attempt to reduce the working of a SWF to the working of a CF involves the adoption of certain positional requirements, whose relationship with the conditions in Arrow's theorem is established.

Forty years of doctoral public relations research in Spain: A quantitative study of dissertation contribution to theory development

In this article, doctoral dissertations on public relations written at Spanish universities (1965–2004) are examined in order to gain an understanding of the level of theory development within the discipline. The following subjects are studied: growth over time, universities where they were written, use of language, gender and the topics of doctoral dissertations. Although still in its early development, public relations doctoral research in Spain is a well-established and burgeoning field in terms of the total of theses examined (62). The conclusion, however, is that their contribution to theory building in public relations has been negligible, with the practical or operational side of public relations standing out more than the conceptual and theoretical side.     

Another impossibility result for normal form games

It is shown that the axioms Cubitt and Sugden (1994; Economic J. 104: 798) impose on a theory of rationally justifiable play (TRJP) do not prevent the possibility that two players necessarily disagree concerning the probability they ascribe to the choice of a third player. This appears to indicate that those axioms are not sufficient for defining a `reasonable' TRJP. In addition, for the case in which a player's beliefs are statistically independent, conditions for a TRJP are suggested under which the existence of a quasi-strict equilibrium is sufficient, but the existence of a consistent n-pair is not, for defining a TRJP meeting those requirements.     

Linear functional regression: The case of fixed design and functional response

The authors consider the problem of simple linear regression when the exogenous and endogenous variables are functional and the design is fixed. They propose an estimator for the underlying linear operator and prove its consistency under some conditions which ensure that the design is sufficiently informative. They consider the classical calibration (or inverse regression) problem and analyze a consistent estimator. They also give a simulation study. The proposed method is not hard to implement in practice.     

Multivariate mixtures of Erlangs for density estimation under censoring

Multivariate mixtures of Erlang distributions form a versatile, yet analytically tractable, class of distributions making them suitable for multivariate density estimation. We present a flexible and effective fitting procedure for multivariate mixtures of Erlangs, which iteratively uses the EM algorithm, by introducing a computationally efficient initialization and adjustment strategy for the shape parameter vectors. We furthermore extend the EM algorithm for multivariate mixtures of Erlangs to be able to deal with randomly censored and fixed truncated data. The effectiveness of the proposed algorithm is demonstrated on simulated as well as real data sets.
