CUMULATIVE ADVERTISING EFFECTS: THE ROLE OF SERIAL CORRELATION*

Since its publication, Palda's [12] initial work which supported the existence of a lagged relationship between advertising expenditures and sales has been frequently discussed and criticized. That criticism has been directed at both methodological and structural issues. This paper is an attempt to answer some of the questions which have been raised regarding the structural issues concerning the role of autocorrelation in Palda's results and to develop the implications of these structural issues for the marketing manager.     

Representing the negotiation process with a rule-based formalism

The objective of this paper is to introduce a flexible approach to the structuring of negotiations. The process of negotiations with its intricacies is discussed, and drawbacks of quantitative methods are analyzed. The decomposition of the negotiation process into a certain hierarchical structure is presented. This structure is represented with and/or trees used for knowledge representation in artificial intelligence. The definitions of flexibility and reactions to the opponent's moves are introduced with the help of a rule-based formalism. The implications of these definitions for the analysis of the negotiation process are presented. The approach is illustrated with a set of hypothetical examples.     

Using critical social theory to develop a conceptual framework for comparative social work

This paper sets out a conceptual framework for comparing and contrasting social work within nation-states and across international boundaries. The framework is "situated" theoretically within a (late)modernist understanding of events within advanced capitalism and draws primarily on Habermas' critical social theory. The authors apply this framework to explicate the development of social work in Northern Ireland, a region in which high levels of political conflict mark it out as a site of local, national and international interest. It is suggested that the ideas developed from the case study have relevance for the social professions in other countries, particularly where social conflict is in evidence.     

Language Experience Shapes the Development of the Mutual Exclusivity Bias

Halberda (2003) demonstrated that 17‐month‐old infants, but not 14‐ or 16‐month‐olds, use a strategy known as mutual exclusivity (ME) to identify the meanings of new words. When 17‐month‐olds were presented with a novel word in an intermodal preferential looking task, they preferentially fixated a novel object over an object for which they already had a name. We explored whether the development of this word‐learning strategy is driven by children’s experience of hearing only one name for each referent in their environment by comparing the behavior of infants from monolingual and bilingual homes. Monolingual infants aged 17–22 months showed clear evidence of using an ME strategy, in that they preferentially fixated the novel object when they were asked to “look at the dax.” Bilingual infants of the same age and vocabulary size failed to show a similar pattern of behavior. We suggest that children who are raised with more than one language fail to develop an ME strategy in parallel with monolingual infants because development of the bias is a consequence of the monolingual child’s everyday experiences with words.     

Madness and gender in the long eighteenth century

The article uses a wide range of archival and literary sources to examine perceptions of mental incapacity. It looks first at what quantifiable measures may and may not tell us about the nature of madness in eighteenth-century Scotland and about the relationship between pathologies and the 'normal' structures of society. It seeks to test a common assumption or assertion that 'madness is a female malady because it is experienced by more women than men' (Showalter). It further questions whether those with mental problems were really just the victims of an oppressive (professional and male) form of discourse by offering a nuanced analysis of the social context in which mental disability was identified. The second half of the article explores certain qualitative aspects of how insanity was construed by the sane, in order to assess the extent of gendering in the day-to-day understanding of mental problems. These aspects include the connections between madness and issues such as emotion, language, class, suicide, alcohol and 'work'.
