Effects of Perceived Quality, Product Category Similarity, and Brand Breadth on Consumers' Perceptions of Brand Extensions: Tests of Categorization Theory and Cognitive Response Theory

Description: Various constructs are related to predicting consumers' perceptions of brand extensions. Among these, three constructs, perceptions of perceived quality (PQ) associated with the parent brand, product category similarity (PCS) of an extension to its parent brand, and brand breadth (BB) of the parent, are central to many brand extension studies. The purpose of this study is to clarify the roles of these three constructs and to pit predictions from an alternative theoretical perspective — cognitiv… more

Effects of Peripheral Nerve Injury on the Cells of the Dorsal Root Ganglion: a Role for Primary Cilia

Description: Primary cilia are ubiquitous sensory organelles found on most cell types including cells of the dorsal root ganglia (DRG). The DRG are groups of peripheral neurons that relay sensory information from the periphery to the CNS. Other cell types in the DRG include a type of glial cell, the satellite glial cells (SGCs). The SGCs surround the DRG neurons and, with the neurons, form functional sensory units. Currently are no reports describing the numbers of DRG cells that have cilia. We found tha… more

Effects of Plasma, Temperature and Chemical Reactions on Porous Low Dielectric Films for Semiconductor Devices

Description: Low-dielectric (k) films are one of the performance drivers for continued scaling of integrated circuit devices. These films are needed in microelectronic device interconnects to lower power consumption and minimize cross talk between metal lines that "interconnect" transistors. Low-k materials currently in production for the 45 and 65 nm node are most often organosilicate glasses (OSG) with dielectric constants near 2.8 and nominal porosities of 8-10%. The next generation of low-k materials wi… more
