TL;DR: Three new heuristics, one for batch and two for on-line, are introduced as part of this research, revealing that the choice of mapping heuristic depends on parameters such as: the structure of the heterogeneity among tasks and machines, the optimization requirements, and the arrival rate of the tasks.
Abstract: Dynamic mapping (matching and scheduling) heuristics for a class of independent tasks using heterogeneous distributed computing systems are studied. Two types of mapping heuristics are considered: on-line and batch mode heuristics. Three new heuristics, one for batch and two for on-line, are introduced as part of this research. Simulation studies are performed to compare these heuristics with some existing ones. In total, five on-line heuristics and three batch heuristics are examined. The on-line heuristics consider; to varying degrees and in different ways, task affinity for different machines and machine ready times. The batch heuristics consider these factors, as well as aging of tasks waiting to execute. The simulation results reveal that the choice of mapping heuristic depends on parameters such as: (a) the structure of the heterogeneity among tasks and machines, (b) the optimization requirements, and (c) the arrival rate of the tasks.

TL;DR: This paper found that neither price nor brand name had significant effects on perceived quality except when product composition characteristics were allowed to vary between product samples, while Brand image had a stronger effect upon quality perception.
Abstract: While price and brand image have both been found to be determiners of product quality perception, the potency of these two cues has never been directly compared. Moreover, those studies which found price to be a determiner of perceived quality manipulated only price information, without permitting actual composition characteristics to vary across brands. A 2X2X2X3 factorial experiment, using 136 adult male beer drinkers, and four test beers, examined the effects of price, composition differences, and brand image cues on the perception of beer quality. Price was found to serve as an indicant of product quality when it was the only cue available but not when embedded in a multicue setting. Brand image had a stronger effect upon quality perception, particularly for brands with strong positive images. In addition, it was found that neither price nor brand name had significant effects on perceived quality except when product composition characteristics were allowed to vary between product samples. Last, in contrast to earlier findings, the data suggest that beer drinkers possess at least some ability to distinguish among different brands of beer on the basis of composition (i.e., taste and aroma) cues alone. As the literature on perceived risk (cf. Cox, 1967) clearly demonstrates, consumer purchase decisions are frequently made under conditions of varying uncertainty regarding the product and its attributes. To reduce such uncertainty, consumers seek and process information regarding the product and generally attempt to form accurate impressions of it. Given that products may be viewed "as an array of cues," the "consumer's task in evaluating a product is to use cues from the array as the basis for making judgments about the product (Cox, 1962, p. 413)." One impression usually of considerable importance to the consumer is the product's (or brand's) quality. Cues relevant to forming impressions of quality include (a) price; (b) product composition characteristics such as taste, aroma, color, style, and size; (c) packaging; (d) brand, manufacturer (i.e., corporate), and store image; (e) advertising; (f) word-ofmouth reports; and (g) past purchase experi

TL;DR: In this paper, a poststructuralist feminist reading of Simon's construct, bounded rationality, is prevented in this paper by a deconstructive process, and bounded emotionality is introduced as an alternative organizing construct.
Abstract: A poststructuralist feminist reading of Herbert Simon's construct, bounded rationality, is prevented in this article. Following from this notion. It is maintained that even though bounded rationality provides a modified critique of “pure” rationality, this concept is grounded in male-centered assumptions that exclude alternative modes of organizing. Through a feminist deconstructive process, bounded emotionality is Introduced as an alternative organizing construct. The premises, conditions of organizing, and implications of this alternative are discussed and illustrated. Finally, theorists are urged to move beyond the traditional dichotomy between rationality and emotionality. In order to question the assumptions that underlie traditional constructs and to create new grounds for future theoretical activities.
