The African Cichlid Fish Astatotilapia Burtoni Uses Acoustic Communication For Reproduction: Sound Production, Hearing, And Behavioral Significance, Karen P. Maruska, Uyhun S. Ung, Russell D. Fernald

Faculty Publications

Sexual reproduction in all animals depends on effective communication between signalers and receivers. Many fish species, especially the African cichlids, are well known for their bright coloration and the importance of visual signaling during courtship and mate choice, but little is known about what role acoustic communication plays during mating and how it contributes to sexual selection in this phenotypically diverse group of vertebrates. Here we examined acoustic communication during reproduction in the social cichlid fish, Astatotilapia burtoni. We characterized the sounds and associated behaviors produced by dominant males during courtship, tested for differences in hearing ability associated with female …

A Study Of Visual Puffery In Fragrance Advertising: Is The Message Sent Stronger Than The Actual Scent?, Mark Toncar, Marc Fetscherin

Faculty Publications

Purpose - This paper investigates visual exaggerations of fragrance advertisements by comparing subjects’ expectations resulting from print ads to their subsequent product evaluations. It then considers whether the actual scents fall short, meet or exceed these expectations.

Design/methodology/approach - By means of a semiotic analysis we capture the corresponding literary attributes of the ads to develop adjective pairs describing the meaning of the ads. Interviews are conducted to assess the meaning that consumers draw from the fragrance ads and we supplement these findings by performing a blind olfactory product evaluation of the fragrances. Paired sample t-tests are used to compare …

Contextual Chemosensory Urine Signaling In An African Cichlid Fish, Karen P. Maruska, Russell D. Fernald

Faculty Publications

Chemosensory signaling is crucial for communication in many fish species, but little is known about how signalers modulate chemical output in response to sensory information and social context. Here, we tested the hypothesis that dominant male African cichlid fish (Astatotilapia burtoni) use urine signals during social interactions, and demonstrate that this signaling depends on social context (reproductive; territorial) and on available sensory information (visual cues; full interaction). We injected males with dye to visualize urine pulses and exposed them to full sensory information or visual cues alone of four types: (1) dominant male; (2) gravid (reproductively receptive) females; (3) mouth-brooding …

Corporate Branding: An Interdisciplinary Literature Review, Marc Fetscherin, Jean-Claude Usunier

Then we used citation mapping to visualize the relationships between and among key works in the field.

Findings: Our search resulted in 264 papers by 412 authors in 150 journals. The field is notably interdisciplinary, with articles published mainly in business, management, …

Visual Framing Of Patriotism And National Identity On The Covers Of Der Spiegel, Andrea Pyka, Scott B. Fosdick, William Tillinghast

Faculty Publications

Patriotism in Germany has been a controversial issue since the Nazi era. Despite the fear and hesitations surrounding the idea of German pride and national identity, Der Spiegel, one of Germany's major national news magazines, showed an increasing visual presence of national identity symbols on its covers following key historical events: the building of the Berlin Wall, the reunification of Germany, the adoption of the euro, and the 2006 World Cup.

The Evolution Of Multi-Component Visual Signals In Darters (Genus Etheostoma), Jennifer M. Gumm, Tamra C. Mendelson

Faculty Publications

As complex traits evolve, each component of the trait may be under different selection pressures and could respond independently to distinct evolutionary forces. We used comparative methods to examine patterns of evolution in multiple components of a complex courtship signal in darters, specifically addressing the question of how nuptial coloration evolves across different areas of the body. Using spectral reflectance, we defined 4 broad color classes present on the body and fins of 17 species of freshwater fishes (genus Etheostoma) and quantified differences in hue within each color class. Ancestral state reconstruction suggests that most color traits were expressed in …

Video Game Design In The Mba Curriculum: An Experiential Learning Approach For Teaching Design Thinking, James Gaskin, Nicholas Berente

Faculty Publications

In the spirit of design thinking, we have developed a ―hands-on‖ video game design workshop intended to be used for an MBA course on design thinking. This novel approach to teaching complex concepts and skills to business students has been received with enthusiasm, and it provides a unique and memorable experience for students to draw on as they encounter situations in which they will apply design thinking in the future. Additionally, student-produced games and student reflections on the workshops provide initial evidence of the value of teaching design thinking through this type of experiential method. In this article we review …

Digital Technology And The Variation In Design Routines: A Sequence Analysis Of Four Design Processes, James Gaskin, B. Veeresh Thummadi, Kalle Lyytinen, Youngjin Yoo

Faculty Publications

We advance a theory of design process variation across organizational types and the effects of digitalization on these processes. We argue that design routines are subject to greater variation within and between organizations as organizations embed increasingly rich repertoires of digital capabilities in their design activities. Using a sequence analysis method we compare design process variation in four organizations to examine how design routines vary due to differences in embedded digital capabilities and organization of the design process. Our analysis reveals new insights on the effects organizational context and digitalization have on design routine composition.

Design Dna Sequencing: A Set Of Methodological Artifacts For Sequencing Socio-Technical Design Routines, James Gaskin, Kalle Lyytinen, Veeresh Thummadi, Douglas Schutz, Youngjin Yoo, Aaron Weiss, Nicholas Berente

Faculty Publications

With the introduction of new digital and physical tools into the workplace, the process of design has dramatically changed over the past few decades. Thus, design processes have evolved into many forms which vary, not only between organizations, but within organizations, and even within teams over time. These myriad “mutations” of the design process call for a new method to identify patterns of design activity and their change in order to deeply understand the design process. In this paper we suggest a new method for identifying patterns of activity in design teams. Such activity involves composites of distributed interactions – …

Gonadotropin-Releasing Hormone And Receptor Distributions In The Visual Processing Regions Of Four Coral Reef Fishes, Karen P. Maruska, Timothy C. Tricas

Faculty Publications

Gonadotropin-releasing hormone (GnRH) is widely distributed in the brain of fishes where it may function as a neuromodulator of sensory processing and behavior. Immunocytochemical and neuronal label experiments were conducted on species from four families of coral reef fishes (Chaetodontidae, butterflyfish; Pomacentridae, damselfish; Gobiidae, goby; and Labridae, wrasse) to assess conservation of GnRH targets in the visual processing retina and brain. In all species, GnRH-immunoreactive (-ir) axons from the terminal nerve project principally to the boundary between the inner plexiform (IPL) and inner nuclear (INL) layers of the retina, and are less prominent in the optic nerve, ganglion cell, IPL …

Phylogeny And Taxonomic Revision Of Nuchequula Whitley 1932 (Teleostei: Leiognathidae), With The Description Of A New Species, Prosanta Chakrabarty, John S. Sparks

Faculty Publications

Nuchequula Whitley 1932, previously considered a subgenus of Leiognathus Lacepède 1802, is elevated to generic rank. Nuchequula is diagnosed by the presence of a distinct saddle-shaped nuchal marking and by the presence of a pigment-free, mitten-shaped region posteroventral to the pectoral-fin base. The genus comprises five species, N. blochii, N. pan, N. nuchalis, N decora, and a new species described herein. Nuchequula mannusella, new species, is distinguished from its congeners by a unique pigmentation pattern on the dorsal fin and morphology of the lower jaw. Redescriptions are provided for the other species. A phylogenetic analysis based on morphological characters, including …

Blended Learning Systems Definition, Current Trends, And Future Directions, Charles R. Graham

Faculty Publications

The term blended learning is being used with increased frequency in both academic and corporate circles. In 2003, the American Society for Training and Development identified blended learning as one of the top ten trends to emerge in the knowledge delivery industry (Rooney, 2003). In 2002, the Chronicle of Higher Education quoted the president of Pennsylvania State University as saying that the convergence between online and residential instruction was “the single-greatest unrecognized trend in higher education today” (Young, 2002, p. A33). Also quoted in that article was the editor of the Journal of Asynchronous Learning Networks, who predicted a dramatic …

Habitat Patch Occupancy Dynamics Of Glaucous-Winged Gulls (Larus Glaucescens) I: A Discrete-Time Model, Karl W. Phillips, Smruti P. Damania, James L. Hayward, Shandelle M. Henson, Clara J. Logan

Faculty Publications

Diurnal habitat occupancy dynamics of Glaucous-winged Gulls were evaluated in a system of six habitats on and around Protection Island, Washington. Data were collected on the rates of gull movement between habitat patches, and from these data the probabilities of transitions between habitats were estimated as functions of tide height and time of day. A discrete-time matrix model based on the transition probabilities was used to generate habitat occupancy predictions, which were then compared to hourly census data. All model parameters were estimated directly from data rather than through model fitting. The model made reasonable predictions for two of the …

Just-In-Time Browsing For Digitized Microfilm And Other Similar Image Collections, William A. Barrett, Douglas J. Kennard

Faculty Publications

This paper describes “Just-In-Time Browsing” (JITB), a method for image browsing (at modem-like speed) in which image data is transmitted and presented to the user progressively, in prioritized order, based on image content and user interaction. Spatial resolution and grayscale or color fidelity is increased first for the portions of the image that are immediately of most interest to the user. JITB is specifically geared toward digitized microfilm and other similar document image collections, although it can also be used for other types of images. A series of common browsing tasks performed by multiple users demonstrates that JITB compares favorably …

Address Code And Arithmetic Optimizations For Embedded Systems, J. Ramanujam, S. Krishnamurthy, J. Hong, M. Kandemir

Faculty Publications

An important class of problems used widely in both the embedded systems and scientific domains perform memory intensive computations on large data sets. These data sets get to be typically stored in main memory, which means that the compiler needs to generate the address of a memory location in order to store these data elements and generate the same address again when they are subsequently retrieved. This memory address computation is quite expensive, and if it is not performed efficiently, the performance degrades significantly. In this paper, we have developed a new compiler approach for optimizing the memory performance of …

Silencing John Doe: Defamation And Discourse In Cyberspace, Lyrissa Lidsky

Faculty Publications

John Doe has become a popular defamation defendant as corporations and their officers bring defamation suits for statements made about them in Internet discussion fora. These new suits are not even arguably about recovering money damages but instead are brought for symbolic reasons — some worthy, some not so worthy. If the only consequence of these suits were that Internet users were held accountable for their speech, the suits would be an unalloyed good. However, these suits threaten to suppress legitimate criticism along with intentional and reckless falsehoods, and existing First Amendment law doctrines are not responsive to the threat …

Caudal Distraction By Rat Snakes (Colubridae, Elaphe): A Novel Behavior Used When Capturing Mammalian Prey, Stephen J. Mullin

Faculty Publications

Caudal movement in snakes may serve either a predatory (e.g., caudal luring) or defensive (eg., rattling, aposematism) function. I describe a new behavioral pattern of tail movement in snakes. Gray rat snakes (Elaphe obsoleta spiloides) foraging on small mammals (Mus domesticus) moved their tails in an erratic, whiplike fashion after detecting their prey in the vicinity. The thrashing movement in the horizontal plane was audibly and visually obvious, resulting in displacement of leaf litter around the tail. All subjects displayed the behavior, but not in all foraging episodes. Shorter durations of caudal distraction resulted in greater …

Understanding Comics: The Invisible Art, Alan D. Manning

Faculty Publications

INSIGHTS about professional communication may come from odd and unexpected places. McCloud's Understanding Comics (hereafter UC) is a case in point. Despite the juvenile connotations evoked by any discussion of comic books, the theory of visual communication presented in UC arguably rivals the best of contemporary semiotics (that is, the study of how we make meaning out of gestures, words, paragraphs, pictures, and so on).
