This article suggests that over the next decade library performance measures - such as output measures - can become the basis for library space planning programs that will determine the quantity and relative location of user hierarchies for each type of public service.

To investigate emotion expression and personality relations, the authors coded infants' full-face and component positive and negative expressions during Episodes 4 through 8 of the strange situation procedure at age 18 months and obtained maternal ratings of the 5-factor model of personality when children were 3.5 years old. Full-face negative expression was directly related to Neuroticism and inversely related to Agreeableness and Conscientiousness. By contrast, component positive expression showed the exact opposite pattern of relations. Full-face positive expression was positively correlated with Extraversion and Openness to Experience. These findings indicate that full-face and component expressions may index different intensities of emotions. Emotion expression and personality relations were not mediated by the security of attachment continuum or the emotional reactivity dichotomy derived from the attachment subclassifications.

A substantial body of theoretical literature testifies to the evolutionary functions of emotions. Relatively little has been written about their developmental functions. This article discusses the developmental functions of emotions from the perspective of differential emotions theory (DET; Izard, 1977, 1991). According to DET, although all the emotions retain their adaptive and motivational functions across the lifespan, different sets of emotions may become relatively more prominent in the different stages of life as they serve stage-related developmental processes. In the first section, we present a brief overview of relevant aspects of the theory. In the second section, we discuss how emotions play a central role in helping the individual achieve developmental milestones and tasks during four major periods of life: Infancy, toddler through preschool years, middle to late childhood, and adolescence. The underlying thesis of this article is that emotions play a central role in stimulating social cognitive attainments at each stage of development. © 1999 Psychology Press Ltd.

Research shows 65-80% of subject search terms fail to match the appropriate subject heading and one-third to one-half of subject searches result in no references being retrieved. In a cross-sectional study, 82 students (3rd grade through college) were presented complex concepts in a naming task. Concreteness, complexity, and syndeticity contributed significantly in explaining match-failure and predicting match-success. The likelihood of match-success following an initial failure is improved by manipulating the values of these three properties. Developmental trends which worked against match-success were observed. It is suggested that match-failure is a consequence of developmental naming patterns and that these patterns can be overcome through the use of metacognitive naming skills.

This report proposes a paradigm for technical journal deselection based on the Bradford Law of distribution, with a demonstration in biomedical communications illustrating various statistical derivations. The model employs the following operational prescriptives: (1) identification of fractional productivities in journal collections; (2) probability predictions for making successful retrievals of relevant items in any given productive fraction; (3) utilization by journal source language and origin; and (4) estimates of cost-efficiencies of searches made in print and machine-readable versions of serial publications. The results suggest that in approximately two out of three trials successful searches ('hits') are likely to be made in a `critical' core of any technical subject collection. The highest probability for retention resides in this portion, about 20% of the publications. We infer that substantial amounts of the remaining publications are candidates for deselection since their information content, as needed, may be captured more cost-effectively through electronic retrieval and document delivery access.

Despite persistent claims regarding the ability of text-based computer-mediated communication to neutralize gender identities, few researchers have worked on the problem of gender distinctiveness in textual production and interpretation, gender judgments, and more importantly, the role of gender in the process of impression formation in electronic communication. Against this background, the author addresses the theoretical aspects of gender in textual communication and places the problem of gender distinctiveness and gender judgments in CIVIC in the context of Hymes' model of communicative competence. He also isolates several variables worthy of investigation, namely, the provision of gender judgments, accuracy, and certainty. He then reconceptualizes the problem of gender distinctiveness and impression formation in CIVIC by bridging the gap between textual markedness and expectations. (C) 2003 Elsevier Ltd.
