Aircraft Cabin Noise Minimization Via Neural Network Inverse Model, Xiao Hu, G. Clark, M. Travis, J. L. Vian, Donald C. Wunsch Jan 2005

Aircraft Cabin Noise Minimization Via Neural Network Inverse Model, Xiao Hu, G. Clark, M. Travis, J. L. Vian, Donald C. Wunsch

Electrical and Computer Engineering Faculty Research & Creative Works

This paper describes research to investigate an artificial neural network (ANN) approach to minimize aircraft cabin noise in flight. The ANN approach is shown to be able to accurately model the non-linear relationships between engine unbalance, airframe vibration, and cabin noise to overcome limitations associated with traditional linear influence coefficient methods. ANN system inverse models are developed using engine test-stand vibration data and on-airplane vibration and noise data supplemented with influence coefficient empirical data. The inverse models are able to determine balance solutions that satisfy cabin noise specifications. The accuracy of the ANN model with respect to the real system …

Mac Law, Kathryn J. Coyne, Alan J. Lewitus, John S. Ramsdell, Harold G. Marshall, Nora J. Deamer, S. Craig Cary, Jason W. Kempton, Steven L. Morton, Parke A. Rublee

Biological Sciences Faculty Publications

Toxicity and its detection in the dinoflagellate fish predators Pfiesteria piscicida and Pfiesteria shumwayae depend on the strain and the use of reliable assays. Two assays, standardized fish bioassays (SFBs) with juvenile fish and fish microassays (FMAs) with larval fish, were compared for their utility to detect toxic Pfiesteria. The comparison included strains with confirmed toxicity, negative controls (noninducible Pfiesteria strains and a related nontoxic cryptoperidiniopsoid dinoflagellate), and P. shumwayae strain CCMP2089, which previously had been reported as nontoxic. SFBs, standardized by using toxic Pfiesteria (coupled with tests confirming Pfiesteria toxin) and conditions conducive to toxicity expression, reliably detected …

Power And The Creation Of Patronizing Environments: The Stereotype-Based Behaviors Of The Powerful And Their Effects On Female Performance In Masculine Domains, Theresa Vescio, Sarah J. Gervais, Mark Snyder, Ann Hoover Jan 2005

Power And The Creation Of Patronizing Environments: The Stereotype-Based Behaviors Of The Powerful And Their Effects On Female Performance In Masculine Domains, Theresa Vescio, Sarah J. Gervais, Mark Snyder, Ann Hoover

Department of Psychology: Faculty Publications

This work tested the following hypothesis: When powerful men stereotype their female subordinates in masculine domains, they behave in patronizing ways that affect the performance of their subordinates. Experiment 1 examined the stereotyping tendencies and patronizing behaviors of the powerful. Findings revealed that powerful men who stereotyped their female subordinates (i.e., those who were weakness focused) gave female subordinates few valued resources but much praise. In Experiment 2, low-power participants received resources (valued or devalued positions) and praise (high or low) from a powerful man. Subordinates who were assigned to a devalued position but received high praise (i.e., the patronizing …

Beyond Patents: The Cultural Life Of Native Healing And The Limitations Of The Patent System As A Protective Mechanism For Indigenous Knowledge On The Medicinal Uses Of Plants, Ikechi Mgbeoji Jan 2005

Beyond Patents: The Cultural Life Of Native Healing And The Limitations Of The Patent System As A Protective Mechanism For Indigenous Knowledge On The Medicinal Uses Of Plants, Ikechi Mgbeoji

Articles & Book Chapters

In the past decade, indigenous knowledge systems have witnessed a belated renaissance, both in policy instruments of international organizations and in some international law agreements. In the progressive emancipation of indigenous knowledge systems, two key issues have arisen. The first is the controversial appropriation of various products, innovations, art forms, and intellectual property of indigenous knowledge systems. A particularly contested aspect of this phenomenon has been characterized as biopiracy. The second closely related issue is whether dominant regimes for the protection of intellectual property are compatible with indigenous knowledge systems.

Parental Responsibility Statutes: An Organization And Policy Implications, Eve M. Brank, Stephanie Carsten Kucera, Stephanie A. Hays Jan 2005

Parental Responsibility Statutes: An Organization And Policy Implications, Eve M. Brank, Stephanie Carsten Kucera, Stephanie A. Hays

Department of Psychology: Faculty Publications

We find ourselves at a confusing time in the history of juvenile justice. As a nation, we are transferring children into an adult system at a greater rate than we have ever seen before. Public response urges that juveniles be locked away not only to punish them, but also to keep the public safe. The public views these delinquent children as a threat and something to fear. Legislators respond to the public fear with more liberal transfer options into the adult system and punitive juvenile sanctions within the juvenile system. If a juvenile escapes transfer into the adult system, then …

Relationship Between Parent Satisfaction Regarding Partnerships With Professionals And Age Of Child, Jean Ann Summers, Lesa Hoffman, Janet Marquis, Ann Turnbull, Denise Poston Jan 2005

Relationship Between Parent Satisfaction Regarding Partnerships With Professionals And Age Of Child, Jean Ann Summers, Lesa Hoffman, Janet Marquis, Ann Turnbull, Denise Poston

Department of Psychology: Faculty Publications

In the past, the assessment of families’ satisfaction with the quality of their partnerships with the professionals who serve their children has been restricted to specific programs or age groups, precluding investigation of the relationship between parents’ perspectives on satisfaction and the importance of partnership components for children at different ages. Differences in policies, service models, and family needs at different life-cycle stages suggest a need to understand how satisfaction might differ among parents of children of different ages. In this study, 147 parents completed the Beach Center Family-Professional Partnership Scale to describe the perceived importance of and satisfaction with …

First Documentation Of Combinatorial Song Syntax In A Suboscine Passerine Species, Daniel Leger Jan 2005

First Documentation Of Combinatorial Song Syntax In A Suboscine Passerine Species, Daniel Leger

Department of Psychology: Faculty Publications

Birds with songs having two or more acoustically distinct elements can arrange them either rigidly (i.e., in the same sequence) or flexibly. Flexible song syntax can be achieved either by varying the number of repetitions of elements or by combining elements in different ways. Combinatorial syntax has been documented only in the songs of oscine passerines and in one nonpasserine, but not in the suboscine passerines. Dawn and day songs of a tyrant flycatcher, the Flammulated Attila (Attila flammulatus), were recorded in Costa Rica. Flexible syntax was noted in both dawn and day song. Attilas not only varied …

After Industrial Citizenship: Market Citizenship Or Citizenship At Work?, Judy Fudge Jan 2005

After Industrial Citizenship: Market Citizenship Or Citizenship At Work?, Judy Fudge

Articles & Book Chapters

This article sketches the rise and fall of industrial citizenship in Canada, and presents two very different models of citizenship that might replace it. It begins by defining the concept of citizenship, and explaining how industrial citizenship has conventionally been understood. It then traces the genealogy of industrial citizenship in Canadian labour law, and how the processes of feminization, deregulation, and globalization have challenged it as a normative ideal and undermined the conditions that have sustained it. The article concludes by considering two scenarios for industrial citizenship in the future: one in which the substance of citizenship is circumscribed by …

Cooperative Brains: Psychological Constraints On The Evolution Of Altruism, Jeffrey R. Stevens, Marc D. Hauser Jan 2005

Cooperative Brains: Psychological Constraints On The Evolution Of Altruism, Jeffrey R. Stevens, Marc D. Hauser

Department of Psychology: Faculty Publications

Imagine an individual called "hunter" that expends a good deal of energy to capture a gazelle. As the hunter is consuming his small prey, a second individual called "recipient" approaches and begins feeding peacefully alongside the hunter. A few weeks later the roles reverse, such that the previous recipient has now captured a gazelle, and the previous hunter is taking advantage of the recipient's hard work. Could the hunter and recipient be Maasai warriors? Is it equally likely that they are common chimpanzees, African lions, or Nile crocodiles? All of these species hunt gazelle and live in groups, so why …

Evolving The Psychological Mechanisms For Cooperation, Jeffrey R. Stevens, Fiery A. Cushman, Marc D. Hauser Jan 2005

Evolving The Psychological Mechanisms For Cooperation, Jeffrey R. Stevens, Fiery A. Cushman, Marc D. Hauser

Department of Psychology: Faculty Publications

Cooperation is common across nonhuman animal taxa, from the hunting of large game in lions to the harvesting of building materials in ants. Theorists have proposed a number of models to explain the evolution of cooperative behavior. These ultimate explanations, however, rarely consider the proximate constraints on the implementation of cooperative behavior. Here we review several types of cooperation and propose a suite of cognitive abilities required for each type to evolve. We propose that several types of cooperation, though theoretically possible and functionally adaptive, have not evolved in some animal species because of cognitive constraints. We argue, therefore, that …

Direct Selling By Urban Farmers: Constraints In Value Creation, Albert C. Manyengawana Jan 2005

Direct Selling By Urban Farmers: Constraints In Value Creation, Albert C. Manyengawana

Masters Culminating Experiences (1993-2011)

According to Heimlich (1989), one of the leading development economists who has published several articles on small and urban farming, there are two major forms of urban farms namely backyard gardens and community gardens. These may, further be classified into recreational, adaptive, and traditional farms. Urban farms emerged as a direct response to beautify the landscape, provide food security and serve as an additional income source. Over time, changes in the farming sector allowed farmers to adopt direct marketing initiatives, circumventing the intermediaries in the distribution chain. These tactics of selling directly to consumers included farmers’ markets, road-side sales, and …

Vertebrate Gld2 Poly(A) Polymerases In The Germline And The Brain, Labib Rouhana, Liaoteng Wang, Natascha Buter, Jae Eun Kwak, Craig A. Schiltz, Tania Gonzalez, Ann E. Kelley, Charles F. Landry, Marvin Wickens Jan 2005

Vertebrate Gld2 Poly(A) Polymerases In The Germline And The Brain, Labib Rouhana, Liaoteng Wang, Natascha Buter, Jae Eun Kwak, Craig A. Schiltz, Tania Gonzalez, Ann E. Kelley, Charles F. Landry, Marvin Wickens

Biological Sciences Faculty Publications

Cytoplasmic polyadenylation is important in the control of mRNA stability and translation, and for early animal development and synaptic plasticity. Here, we focus on vertebrate poly(A) polymerases that are members of the recently described GLD2 family. We identify and characterize two closely related GLD2 proteins in Xenopus oocytes, and show that they possess PAP activity in vivo and in vitro and that they bind known polyadenylation factors and mRNAs known to receive poly(A) during development. We propose that at least two distinct polyadenylation complexes exist in Xenopus oocytes, one of which contains GLD2; the other, maskin and Pumilio. GLD2 protein …

Towards Wide-Field Display Of The Gripen Hud Interface To Combat Spatial Disorientation, Lars Eriksson, Katarina Undén, Claes Von Hofsten Jan 2005

Towards Wide-Field Display Of The Gripen Hud Interface To Combat Spatial Disorientation, Lars Eriksson, Katarina Undén, Claes Von Hofsten

International Symposium on Aviation Psychology - 2005

The head-up display (HUD) interface of the Gripen fighter aircraft utilizes a sphere concept for supporting attitude awareness or spatial orientation (SO). With the sphere interface fixed to the gravitational vertical and the attitude variant aircraft positioned in the center of the sphere, the HUD field-of-regard scans parts of the sphere inside. The HUD interface depicts segments of latitude circles with meridian markings that convey integrated information of pitch, roll, and yaw. To enhance pilot-in-the-loop maneuvering and SO we suggest a wide field-of-view interface design of the Gripen concept, emphasizing the inclusion of peripheral vision. The suggested interface is subsequently …

A Conceptual Framework For Studying Safety Climate And Culture Of Commercial Airlines, Dr. Sharon Glazer, Amber R. Laurel, Rangapriya Kanan Narasimhan Jan 2005

A Conceptual Framework For Studying Safety Climate And Culture Of Commercial Airlines, Dr. Sharon Glazer, Amber R. Laurel, Rangapriya Kanan Narasimhan

International Symposium on Aviation Psychology - 2005

A comprehensive safety climate and safety culture framework, which can be utilized to assess various predictors and consequences of safety climate and to assess airline’s safety culture in relation to one another, is presented. The framework depicts a process whereby individual, group, and organizational predictor variables, through perceived safety climate, affect first level outcomes. First level outcomes can lead to direct costs for the organization, as well as lowered productivity. In the framework, individual and environment variables are purported to moderate the relationship between work-related events and safety climate. Motivation is also expected to mediate the relationships between predictors and …

Distributed Air / Ground Traffic Management En Route Free Maneuvering Rules Of The Road: Requirements And Implementation For A Simulation Of En-Route Self-Separation, Nancy H. Johnson, Riva Canton, Vernol Battiste, Walter Johnson Jan 2005

Distributed Air / Ground Traffic Management En Route Free Maneuvering Rules Of The Road: Requirements And Implementation For A Simulation Of En-Route Self-Separation, Nancy H. Johnson, Riva Canton, Vernol Battiste, Walter Johnson

International Symposium on Aviation Psychology - 2005

National Aeronautics and Space Administration’s (NASA) Distributed Air Ground Traffic Management (DAG-TM) program has recently investigated a concept called “En-route Free Maneuvering” as a proposed solution for expanding airspace capacity limits. A critical element for this concept is conflict detection and resolution (CD&R) using the 3D cockpit situation display (CSD). The only fielded system performing some of this function is the Traffic Alert & Collision Avoidance System (TCAS), a radar-based alerting system used by most commercial aircraft for collision detection and avoidance. TCAS is inappropriate for an en-route self-separation application due to its reactive nature, and inherent lack of flexibility. …

Redefining Crm, J. Norman Komich Jan 2005

Redefining Crm, J. Norman Komich

International Symposium on Aviation Psychology - 2005

The recent revision (120-51E, dated 1/22/04) to the Crew Resource Management Training Advisory Circular failed to provide a specific definition of CRM. This void is an issue with those who agree with Montaigne when he observed “No wind favors the sailing ship without a destined port.” Since its inception over twenty five years ago, CRM has undergone considerable evolution and the industry now finds itself in the seventh or eighth “Generation” of CRM training. Interestingly, in the very first Advisory Circular (120-51A) the following statement was made: “The essence of CRM training is to reduce error in the cockpit.” In …

The Relationship Between Controller Opinions And Use Of An Atc Decision Support Tool, Carol A. Manning, Melanie Dennis Jan 2005

The Relationship Between Controller Opinions And Use Of An Atc Decision Support Tool, Carol A. Manning, Melanie Dennis

International Symposium on Aviation Psychology - 2005

The purpose of this study was to assess the relationship between controllers’ opinions about the User Request Evaluation Tool (URET), an air traffic control decision support tool, and their use of various URET functions, including its flight data management capabilities, conflict prediction information, and problem-solving tools (e.g., trial planning). We expected that, compared with those who were less positive about URET, controllers who rated the tool more positively would use it more often in performing sector team duties. In 2002, formal observations were made of 181 en route controllers using URET at six facilities. URET display settings, usage, and use …

Team Coordination In Uav Operations, Harry K. Pedersen, Nancy J. Cooke

International Symposium on Aviation Psychology - 2005

The term “unmanned” in the context of unmanned aerial vehicle (UAV) operations is too often taken literally, overlooking the humans controlling, monitoring, collaborating, and coordinating from the ground. Promoting and improving the performance of the human component in the operation of UAVs is paramount and enhancing the coordination of the humans in the system is one of many important human factors issues which must be overcome. Research from the Cognitive Engineering on Team Tasks Laboratory has approached this problem with the development of a synthetic test-bed replicating UAV coordination in the lab. Findings from this synthetic task environment (STE) will …

Near-To-Eye Display And Augmented Reality Concepts For Air Traffic Tower Controllers: Issues And Challenges, Dr. John W. Ruffner, Dr. Jim E. Fulbrook, Marc Foglia

International Symposium on Aviation Psychology - 2005

Tower controllers are responsible for maintaining safe separation between airborne aircraft in the airport traffic control area, and separation between aircraft, equipment, and personnel on the airport surface. In this paper, we summarize recent work to develop and evaluate user-acceptable hardware and software solutions that will reduce diversions and augment or enhance controller capabilities, especially in limited visibility conditions. We characterized controller tasks where a near-to-eye display and augmented reality techniques can aid controller performance, and identified form factor variables that influence user acceptability of hardware configurations. We developed an out-the-window concept of operation and analyzed the hardware requirements and …
