(Un)Gendered Sentiments: The Relationship Between Modernism And Gender In The Works Of Barnfield And Woolf, Brittany Kay Jungck

Dissertations and Theses @ UNI

By examining the history of literature through the lens of a gender critic, a person is able to discern how society and history frame our understanding of certain concepts. In this study, I have examined the lives and works of Richard Barnfield, a famed poet from the English Renaissance, and Virginia Woolf, a noted twentieth-century British novelist. The analysis of various aspects of Barnfield's and Woolf's creations reveals a connection between gendered language and modernity.

Machining Process Changes As A Function Of Surface Roughness, Specific To Machining Cylindrical Bores, Thomas Patrick Olsen

Dissertations and Theses @ UNI

Manufacturing professionals are challenged everyday to produce products to higher quality standards in a way that is economical and efficient. Manufacturing needs to minimize non value added costs such as reducing inventory, (non machined and finished goods), reduce work in process, and most of all eliminate waste. To exist, customers must be satisfied at the time of purchase and throughout the products lifecycle. To be competitive and remain a world class manufacture, companies must be flexible and be willing to change. Single point flexible manufacturing versus fixed spindle rigid machining greatly improves the ability to make changes. If a process …

Gender Inequalities In Toddler Confrontation Teachers' Responses, Jessica Hermeyer

Dissertations and Theses @ UNI

This research examined the differences in confrontational interaction between boy and girl toddlers, and differences in how caregivers react to the children involved based on the children's gender. It is important to examine these differences in order to understand how gender differences are reproduced as children are socialized in day care culture.

Using content analysis of teacher-reported incidents occurring in a day care center, I explore the details of toddler confrontational behaviors from the teachers' perspectives following the incidents. My findings indicate that during confrontational interaction the children's gendered behavior in this study was similar to adults' gendered behavior revealing …

Differential Double Capture Cross Sections In P+He Collisions, Michael Schulz, T. Vajnai, J. A. Brand

Physics Faculty Research & Creative Works

We have measured differential double capture cross sections for 15 to 150 keV p+He collisions. We also analyzed differential double to single capture ratios, where we find pronounced peak structures. An explanation of these structures probably requires a quantum-mechanical description of elastic scattering between the projectile and the target nucleus. Strong final-state correlations have a large effect on the magnitude of the double capture cross sections

Effects Of The Final-State Electron-Ion Interactions On The Fully Differential Cross Sections For Heavy-Particle-Impact Ionization Of Helium, Don H. Madison, Jerry Peacher, M. Foster, K. Bartschat, H. P. Saha, Allison L. Harris

Physics Faculty Research & Creative Works

Three-dimensional fully differential cross sections for heavy-particle-impact ionization of helium are examined. Previously, the three-body distorted-wave (3DW) model has achieved good agreement with experiment in the scattering plane for small momentum transfers, but poor agreement for large momentum transfers. Poor agreement was also observed outside the scattering plane for all momentum transfers. In particular, the 3DW calculations predicted cross sections that were too small both perpendicular to the scattering plane and for large momentum transfers. The important unanswered question concerns the physical effects that cause the significant disagreement between experiment and theory. In previous works, the role of the projectile-ion …

Hegemonic Masculinity Within Television Commercials, Jonathan A. Hutchins

Dissertations and Theses @ UNI

This study examines the portrayal of masculinity and the socialization patterns that can be found within television commercials. Television commercials' depiction of social members and their roles act as guides for social members in which they desire to portray during day to day social interactions and situations. Social members are generally unaware of this social phenomenon because they take for granted their social world and the logistics within it. While television commercials aim to create and encourage consumption, the purchasing of a product, service or event, television commercials also create and encourage social members to believe that these advertised items …

Perceptions Of Parental Rejection, Peer Rejection, And Peer Victimization In Relation To Self-Reported Depression, Clayton Joseph Egli

Dissertations and Theses @ UNI

The present study compared perceptions of parental rejection, peer rejection, peer victimization, and depression in a sample of children from the Midwest. Self-report measures were completed by 71 participants (ages 7-12) in their regular classroom setting. Correlational analyses were conducted and found significant positive relationships between the identified constructs. Maternal rejection, paternal rejection, relational victimization, overt victimization, and peer rejection were found to correlate with depression for girls. Boys had significant correlations for maternal rejection, paternal rejection, and relational victimization with depression. Overt victimization did not significantly correlate with depression for boys. The peer rejection measure showed insufficient reliability for …

Validation Of The Suicide Resilience Inventory-25 (Sri-25) With Chinese And American College Students, Qijuan Fang

Dissertations and Theses @ UNI

This study examined the psychometric properties of the Suicide Resilience Inventory-25 (SRl-25; Osman et al., 2004) among Chinese and American college students. This instrument was designed to tap into the factors that help defend against suicidal thoughts and behaviors and includes three factors: Internal Protective (IP), External Protective (EP), and Emotional Control (EC). Three hundred and eighteen Chinese college students and 328 American college students completed the Chinese or English version of the SRI-25, the Multi-Attitude Suicide Tendency scale (MAST; Orbach et al., 1991), and the Suicide Behaviors Questionnaire-Revised (SBQ-R; Osman et al., 2001). American participants scored significantly higher on …

The Role Of Interpersonal Communication As A Branch Of Relationship Management In Law Enforcement, Nermin Ferkic

Dissertations and Theses @ UNI

Police officers are often recognized as tough action figures whose only job is to fight ruthless criminals. A highly rated TV show called "Cops" presents police officers as such figures. Police officers drive noticeable squad cars with top lights and a printed motto reading "to protect and serve." They are well known for their work equipment, such as: night sticks, pepper sprays, armor, handcuffs, and most noticeably, guns. This, of course, easily confirms people's idea that police officers' jobs are all about using their physical abilities. However, while working as a police officer and with police officers I realized that …

Framed: Youth Conceptions Of Citizenship, Jennifer Lea Farrell

Dissertations and Theses @ UNI

Much attention has been paid to the youth voting record and youth participation in politics and civic activities. Some recent scholarship suggests that youth are apathetic and disengaged. Other scholars argue for a more inclusive definition of citizenship and analyze youth's involvement in various service activities. Further analysis of youth voting and conceptions of citizenship is needed in order to mobilize youth and work to sustain a healthy democracy. The MTV "Choose or Lose" Campaign encourages youth voters to get registered, get educated and vote. In 2004 the "Choose or Lose" Campaign increased the ante by offering one youth a …

Breaking The Cycle-Preventing Failures By Leveraging Historical Data During Conceptual Design, Daniel A. Krus, Katie Grantham

Engineering Management and Systems Engineering Faculty Research & Creative Works

Major engineering accidents are often caused by seemingly minor failures propagating through complex systems. One example of this is an accident involving a Bell 206 Rotorcraft where a fuel pump failure led to the severing of the tail boom. Cataloguing and communicating the knowledge of potential failures and failure propagations is critical to prevent further accidents. The need for effective failure prevention tools is not specific to rotorcrafts, however. Failure reporting systems have been adopted by various industries to aid and promote failure prevention. The catalogued failures usually consist of narratives describing which part of a product failed, how it …

Rfid Instrumentation In A Field Application, Theresa M. Swift, Martha J. Molander, Steve Eugene Watkins

Electrical and Computer Engineering Faculty Research & Creative Works

The behavior of radio-frequency identification (RFID) tags is investigated in a field application. The RFID instrumentation is used to mark the position of point strain sensors in a fiber-reinforced polymer (FRP), short-span bridge. The tags are surface mounted on carbon FRP structural elements and covered with a resin wear layer, i.e. the deck of the bridge. The smart composite bridge was installed in 2000 and serves as a field testbed for various sensor technologies including the RFID tags. The operation of the RFID network is tested in the field and compared to laboratory tags. Specific research issues include long-term survivability …

Spatial Diversity In Signal Strength Based Wlan Location Determination Systems, Anil Ramachandran, Jagannathan Sarangapani

Electrical and Computer Engineering Faculty Research & Creative Works

Literature indicates that spatial diversity can be utilized to compensate channel uncertainties such as multipath fading. Therefore, in this paper, spatial diversity is exploited for locating stationary and mobile objects in the indoor environment. First, space diversity technique is introduced for small scale motion and temporal variation compensation of received signal strength and it is demonstrated analytically that it enhances location accuracy. Small scale motion refers to movements of the transmitter and/or the receiver of the order of sub-wavelengths while temporal effects refer to environmental variations with time. A novel metric is introduced for selection combining in order to improve …

Wave Propagation On Power Cables With Special Regard To Metallic Screen Design, R. Papazyan, Per Pettersson, David Pommerenke

Electrical and Computer Engineering Faculty Research & Creative Works

The high frequency properties of coaxial power cables are modeled using time- and frequency-domain numerical simulations. This is required due to the complex helical structure of the outer metallic screen. The finite element (FEM) and finite difference time domain methods (FDTD) have been employed to study the effect of screen spiralization. It is established that this screen design causes a dependence of the cable high frequency characteristics on the surrounding medium. Analytical model based on modal analysis of wave propagation in coaxial cables confirms the numerical observations.

Asymptotic Stability Of Nonholonomic Mobile Robot Formations Using Multilayer Neural Networks, Jagannathan Sarangapani, Travis Alan Dierks

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, a combined kinematic/torque control law is developed for leader-follower based formation control using backstepping in order to accommodate the dynamics of the robots and the formation in contrast with kinematic-based formation controllers that are widely reported in the literature. A multilayer neural network (NN) is introduced along with robust integral of the sign of the error (RISE) feedback to approximate the dynamics of the follower as well as its leader using online weight tuning. It is shown using Lyapunov theory that the errors for the entire formation are asymptotically stable and the NN weights are bounded as …

A Normalized Fractionally Lower-Order Moment Algorithm For Space-Time Adaptive Processing, Y. Rosa Zheng, Genshe Chen, Erik Blasch

Electrical and Computer Engineering Faculty Research & Creative Works

A new space-time adaptive processing algorithm is proposed for clutter suppression in phased array radar systems. In contrast to the commonly used normalized least mean square (NLMS) algorithm which uses the second order moments of the data for adaptation, the proposed method uses the lower order moments of the data to adapt the weight coefficients. The normalization is also performed based on the data sample dispersion rather than the variance. Processing results using simulated and measured data show that the proposed algorithm converges faster than the NLMS algorithms in Gaussian and non-Gaussian clutter environments. It also provides better clutter suppression …

Channel Estimation And Phase-Correction For Robust Underwater Acoustic Communications, Y. Rosa Zheng

Electrical and Computer Engineering Faculty Research & Creative Works

This paper presents a new channel estimation, equalization, and phase correction scheme to combat the convergence and stability problem encountered by time-domain adaptive equalizers in underwater acoustic communication systems. Large Doppler spread and symbol scaling in underwater channels have been challenging problems causing significant phase drift and performance degradation. Our new method targets this problem by first allowing phase errors in the estimation of the fading channel coefficients and then perform group-wise (rather than symbol-wise) phase estimation and correction after equalization and multiple channel combining. Single transmitter and multiple receiver data obtained through ocean experiments have been processed using the …

Cross-Regional Trade Cooperation: The Mexico-Japan Free Trade Agreement by Sarita D. Jackson

Latin American and Asia-Pacific countries are fervently forging economic cooperative relationships, which began with the Asia-Pacific Economic Cooperation in 1989. The two regions have shifted away from looking intra-regionally for economic stability against the forces of globalization. Rather, they have moved towards emphasizing cross-regional trade pacts. Cross-regional trade pacts present a number of advantages for member countries. The Mexico-Japan FTA, as a case study, shows us that trade and FDI between member countries increase with cross-regional free trade agreements (FTA). …

A Growth Theory Perspective On The International Diffusion Of Electronic Commerce., S.C Ho, Robert John Kauffman, T.P. Liang

Research Collection School Of Computing and Information Systems

Information and communication technologies (ICTs) continue to have a profound effect on the economies and societies where they are used. In this article, we propose three related theories to describe the underlying mechanism for growth in e-commerce revenues at the national level. Endogenous growth theory posits that the primary drivers of e-commerce growth are internal to a country. Exogenous growth theory suggests that the primary drivers of e-commerce growth are external to an economic system, and reflect the forces of the regional economy. A blend of these, a mixed endogenous–exogenous growth theory, incorporates drivers from both the economy and …

Cultural Values Reflected In Arab And American Television Advertising, Morris Kalliny, Lance Gentry

Business and Information Technology Faculty Research & Creative Works

This study examines cultural values as reflected in U.S. And the Arab world television advertising. A total of 866 television commercials from Egypt, Kuwait, Lebanon, Saudi Arabia, United Arab Emirates and the United States were analyzed. Contrary to the common notion that the U.S. culture and the Arabic culture are vastly different, we found many similarities between the two cultures regarding TV advertising content and appeal. The findings contribute to the debate of standardization versus adaptation of international advertising.

Good Things Come In Small Packages: Tiny Plankton Producing Oxygen Near Dead Zone, Abbie Basile

Libraries Faculty & Staff Publications

(First paragraph) For many, the words “Lake Erie” bring to mind large things: big sport fish, sprawling waterfront homes, and an enormous body of water bordering four states and two countries. Similarly, much of the Lake Erie research of which the public is aware deals with larger biological organisms—larger algae and zooplankton, the small fish that eat the zooplankton, and the large fish that feed on those smaller fish. Over the years, the smaller lake life have been somewhat overlooked.

The Practitioner, The Priest, And The Professor: Perspectives On Self-Initiation In The American Neopagan Community, Marty Laubach, Louis Martinie’, Roselinda Clemons

Sociology and Anthropology Faculty Research

Initiation is a religious practice that is generally understood as involving socialization and acceptance into a religious community, but American Neopaganism, with its emphasis on individualism and autonomy, has evolved a meaning that challenges that simple understanding. American Neopagan communities are marketplaces of ideas that are comprised of groups and solo practitioners, all in interaction in which they might conduct main holidays together, but not necessarily work together in what they would consider more “serious” practices in which they receive the spirit communications with which they develop the ideas. Among groups, these practices include initiations through which candidates are trained …
