  • Why is the market share of accounting measures shrinking, and can cross-sectional differences in the extent of shrinkage be explained? Has the information content of accounting information itself deteriorated, or should we look to more fundamental changes in the economic environment? For example, Milliron (2000) documents a significant shift over the past twenty years in board characteristics measuring director accountability, independence, and effectiveness consistent with a general increase in directors’ incentive alignment with shareholders’ interests.

  • These limitations arise because the P2P world is lacking in the areas of semantics, data transformation, and data relationships, yet these are some of the core strengths of the data management community. Queries, views, and integrity constraints can be used to express relationships between existing objects and to define new objects in terms of old ones. Complex queries can be posed across multiple sources, and the results of one query can be materialized and used to answer other queries.

  • Since the early 1980s, much time and effort has been expended in trying to understand the relative contributions of different social factors in mortality decline (especially declines in infant and child mortality) and in reductions in fertility. In these debates, the schooling level (number of years attended) of a young mother has often been portrayed as the single most powerful correlate of reductions in the infant and child mortality of her children, and (to a lesser but still very considerable degree) to reduction in her completed family size.

  • We begin with the simplifying assumption that the individual has only one opportunity to enter business school at period t = k. 23 We further focus attention on full-time students. At t = k−1, an individual chooses whether or not to enter business school in the next period k. There is a cost to attending business school, ci + ηik, which is assumed to be observed by the individual at the time of the decision. The first term, ci, denotes the individual-specific costs that can be measured by the econometrician (i.e.

  • Psychologist H.J. Eysenck’s studies support the existence of an objective factor of aesthetic appreciation independent of individual tastes. Eysenck described a “general factor” underlying aesthetic discrimination [Eys40][Eys72]. Eysenck asked observers to rank over 300 pictures of portraits, vases, clocks, ships, and so forth, in the order of liking. The subjects and pictures were chosen to eliminate irrelevant associations due to the cultural background of the sub- jects, the technical execution of the images, and subjects’ familiarity with the images.

  • Additional projects studied the transfer of contaminants from females to pups, the impact of contaminants on immune system function, seasonal movements, diving activity and the measurement of heart rate as an indication of energy expenditure. Scientists have also observed the seal hunt in order to collect data on the age composition of the harvest as well as on “struck and loss”. In any harvest, animals may be killed but not recovered and therefore not included in the reported landings, a factor referred to as “struck and loss”.

  • Williams and Wessel (2004) studied weekly reflective journal entries of 48 physical therapy students, using five levels of reflection (Williams et al. 2000). The five levels, from the least to the most analytic, and the number of students who achieved each were: ‘describes learning’ and ‘analyses learning’ (both 100%); ‘verifies learning’ (96%); ‘gains a new understanding’ (66%); and, ‘indicates future behaviour’ (25%). The studies of students involve larger numbers of participants, and over several pro- fessions and levels of learners.
