The purpose of this study is to revise the genus Suwallia and to evaluate the potential taxonomic importance of adeagal and other genitalic characters, adult pigment patterns and egg characters. The revision concentrates on western North American species while providing coverage of all species, except Suwallia asiatica Zhiltzova and Lavanidova where only presumed females have been available for study. Communication and mate locating behaviors in adult stoneflies are critical for life cycle completion and species perpetuation. Drumming signals are known for numerous species of Plecoptera, but mate searching patterns and specifically, if or how vibrational communication is utilized for locating mates are virtually unknown for all stonefly species. I conducted field or laboratory studies of three species to elucidate mate searching patterns and how vibrational communication is used for locating mates. The species studied included a bushtopper, Suwallia pallidula (Banks); a ground scrambler, Claassenia sabulosa (Banks); and treetopper, Perlinella drymo (Newman). The "fly-tremulate-search". "rock to rock" and "fly-drum-search" search patterns exhibited by these species are described, as well as how vibrational communication is used for mate finding. Vibrational signal production by tremulation is reported for the first time in Suwallia, and for only the second time Plecoptera.

A basic relationship between stethoscopic auscultation and background noise interference was reviewed and examined in this study. The principle experimental design of the study questioned whether hospital background noise levels are capable of masking the threshold of detection for auscultated heart sounds. Several cited studies monitoring background noise levels in various hospital locations have reported averages exceeding the U.S. Environmental Protection Agency (EPA) (1974) and World Health Organization (WHO) (1980) recommendations of "quiet", namely 35 to 40 dBA (Falk & Woods, 1973; Hilton, 1985, 1987; Shapiro & Berland, 1972; Turner, et al., 1975; Woods & Falk, 1974) by as much as 46 to 51 dB, i.e., up to 86 dBA (Shapiro & Berland 1972). In addition to the previous query, a review of the literature reflected a lack of implementatory standards regarding the acoustic stethoscopic output and the masking effects of noise during the auscultation process. Specifically, this study ascertained the effective masking level (EML) intensities of two noise environments, white noise and cafeteria noise, for cardiac auscultation through an acoustic stethoscope and an amplified stethoscope. Two principle measurements were employed in the experimental protocol: an objective measurement employing a method of adjustment detection identification task of the EML, and subjective responses solicited by a forced-choice questionnaire. Sixteen normal hearing listener's were selected to participate in the experiment. Objective measures were analyzed using a MANOVA and a Pearson Product Moment Coefficient of correlation. The subjective questionnaire data were analyzed with a two-tailed T-test. All analyses were based on a .05 level of confidence.

The present study focuses on students at two Swedish secondary schools and the pronunciation errors that are the most prominent during reception and production of specific speech sounds. The primary focus of this degree paper is to establish whether or not certain speech sounds such as e.g. the /tʃ/ sound, which do not occur in the Swedish language in initial position are difficult or not and whether or not they act as an obstacle for Swedish students learning English as their L2. The aim was to establish which specific pronunciation errors that occurred in the L2 language classroom. Since this was the aim, primarily quantitative studies were carried out at two secondary schools in southern Sweden. The results from the four different tests show that the tested Swedish L2 students seem to have a greater difficulty with speech sounds placed in initial position than in final position of a specific word. According to this degree paper this is due to the fact that the Swedish language does not have an equivalent to the difficult speech sound in initial position, therefore making it difficult and often resulting in negative transfer from the L1. Furthermore, the English sounds that posed the biggest problems for the students were ones that sometimes can be found in the Swedish language. These sounds were very similar to native sounds creating a challenge for the Swedish students when perceiving and producing the English sounds. However, it was shown that when these sounds were presented in a context, they proved to be less challenging for the students to receive and produce. Moreover, although the syllabus only mentions that communication should be functional, there still needs to be an element of focus on form in order to become a proficient language user.

The purpose of this study was to determine the effects of an auditor's past musical training and experience on the intelligibility of selected vowel sounds at differential pitch levels. The specific problems of the study were to investigate the effects of extensive vocal music training, extensive non-vocal music training, and limited or no music training on an auditor's ability to discriminate accurately selected vowel sounds performed at various pitch levels. The effects of pitch and vowel sound on auditor recognition of vowel sounds in singing and the ability of each singer to be intelligible to auditors was also investigated.

In an industry plagued by high failure rates and exorbitant amounts spent on marketing, restaurants must find ways to increase the efficiency of their advertising. Present research demonstrates linkages between human senses and emotions and affective responses to marketing stimuli (e.g. Peck and Wiggins, 2006). However, there is presently a dearth of research addressing how advertising can creatively draw upon consumers' senses to elicit the desired responses by stakeholders (e.g. increased purchase intent). In response to this apparent gap in our inquiry, the purpose of this study is to explore how verbal smell references (e.g. "You can almost smell the smoky and delicious aroma of your steak grilling to perfection" stated in the ad) and congruent cooking sounds (e.g. sizzling sounds for a steakhouse) in radio food advertisements impact consumer sensory perceptions (ability to almost taste and/or almost smell the advertised product), affective response, and purchase intentions. In addition, since current research indicates that olfactory perceptions can vary by gender (e.g. (Doty, Shaman, and Dann, 1983; Cane, 1982), this research tested for gender-based differences in these hypothesized relationships. Regarding procedures, a sequence of two pretests were used to establish the reliability and validity of the verbal smell reference used in this research. In addition to these manipulation checks on the verbal smell reference construct, the two pretests also verified that undergraduate students would have the ability to adequately relate to the experimental setting — steakhouses. Next, a 2x2x2 between-subjects experiment was conducted in which the verbal smell reference was manipulated, congruent cooking sounds were manipulated, and gender was measured. Results indicate that a verbal smell reference in a radio ad does significantly influence a potential consumer's ability to almost smell and to almost taste the advertised product. The smell reference also significantly impacts individuals' affective responses to the ad and purchase intent of the product. Interestingly, this research also found that the level of "excitement" associated with the advertised brand perfectly mediates the relationship between the verbal smell reference and affective responses. That is, the verbal smell reference leads consumers to assess the advertised brand as being exciting which, in turn, results in positive affective responses. This research did not detect any significant outcomes associated with the use of congruent cooking sounds in radio ads or any significant interactions between cooking sounds and verbal smell references with regard to the outcome variables. Further, gender was not found to significantly intervene in any of the hypothesized relationships. Nevertheless, the significant outcomes associated with the main effect of the verbal smell references on consumer sensory perceptions (ability to almost taste and/or almost smell the advertised product), affective response, and purchase intentions, along with the mediation of the excitement construct, are associated with formidable theoretical and managerial implications which are discussed in the concluding chapter of this thesis. / Master of Science

This study dealt with the perception of dissonance by male, female, freshman and senior music majors. A test was devised which would show that there is a significant difference in dissonance perception between freshman versus senior and male versus female music majors, utilizing specific excerpts from the musical repertoire. Test item analysis was also employed to determine if a significant difference occurs in each excerpt. It was found that certain excerpts show a significant difference while the means of the combined groups do not. This phenomenon was because of relative uncertainty in response between dissonant ("four") and extremely dissonant ("five") excerpts. The conclusions of the study based upon the hypotheses were the following: 1. Four years in a university environment makes a significant difference in a music major's perception of dissonant sounds in music. 2. The sex of the music major causes no significant difference in the perception of dissonance. Male responses were consistent with female responses within the same class.
