Ontogeny Of Visual And Mechanosensory Structure And Function In Atlantic Menhaden Brevoortia Tyrannus, Dennis M. Higgs, Lee A. Fuiman

Biological Sciences Publications

The importance of visual, mechanoreceptive and auditory inputs to escape responses was examined in larvae of the Atlantic menhaden (Brevoortia tyrannus) presented with a simulated predatory stimulus. Ontogenetic changes in the retina, superficial neuromasts and auditory bullae were examined in concert with behavioral trials in which sensory inputs were selectively blocked. Menhaden larvae showed a decrease in cone photoreceptor density and first developed rod photoreceptors when their total length (TL) reached 8-10 mm; they began summing photoreceptive inputs at 12-14 mm TL. Inflation of the auditory bullae was complete by 15 mm TL. The proliferation of superficial neuromasts varied depending …

National College Health Risk Behavior Survey Of Western Washington University Students, Spring, 1995, Gary (Gary Russell) Mckinney, Patricia M. Fabiano, Joseph E. Trimble

Office of Institutional Effectiveness

In May, 1995, the National College Health Risk Behavior Survey-developed by the Centers for Disease Control and Prevention (CDC)-was mailed to 1,000 randomly selected Western Washington University students. The final tally of completed forms was 482, a 48.2% survey response rate. The National College Health Risk Behavior Survey was established by the CDC to monitor the prevalence of behaviors most influencing the health of college students. In addition to Western students, the survey was administered to over 10,000 representative college students nationwide. (Baseline data from that administration was not available at the time of the publication of this report). The …

Infant Physical Attractiveness, Affect, Temperament, And Gender In Relation To Tester Behavior, Andrea D. Hart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Easily observable infant characteristics have been shown to influence others; perceptions of infant competence. This study examined the relation between infant characteristics and a tester's willingness to repeat opportunities for the infant to pass items during administration of a cognitive test. Results showed that infant physical attractiveness was related to lower elicited infant performance (the ratio of items initially failed). Positive affect was related to higher test scores. Because first impressions are likely to contribute to future relationships, it may be important to educate adults who interact with infants about the effects of stereotyping infants based on first impressions.

Effects Of A Parent's Intervention To Decrease Stereotypic Behavior And Increase Interactions Using Self-Management Treatment For Students With Autism In Korea, Jeongil Kim

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The present investigation examined the effects of a parent's intervention to teach students with autism self-management to decrease their stereotypic behaviors. A time-lagged ABA (A represents the first baseline, B does intervention, and A does the second baseline) design was used. Three mothers of children with autism were trained to reduce their children's stereotypic behaviors using a self-monitoring strategy. The training for the parent was conducted in two settings after the first baseline condition. A classroom was used for the first training session and the home was used for the second training session. The intervention by the parent was conducted …

A Survey Of Perceived Control And Domestic Environment Aspects Of Early Adolescent Boys With And Without Identified Externalizing Behavior Problems, Gary W. Mauk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two demographically congruous groups of early adolescent boys, one group with identified externalizing behavior problems (ESP) and one group enrolled in regular education (RED), were surveyed using anonymous self-report questionnaires that assessed academic, social, and general domains of perceived control and aspects of familial experiences. Data from EBP and RED boys' extant scholastic archival records were also collected. Also, using anonymous self-report questionnaires, the parents of EBP and RED boys were surveyed regarding their levels of satisfaction regarding aspects of parenting.

This study found that EBP boys had statistically significantly lower reading, math, and language achievement scores and grade point …

Host-Plant Effects On The Behavior Of Eretmocerus Sp. Nr. Californicus Females Raised From Melon, David H. Headrick, Thomas S. Bellows, Jr., Thomas M. Perring

Horticulture and Crop Science

The behaviors of female Eretmocerus sp. nr. californiens raised from Bemisia argentifolii Bellows & Perring on melon, Cucumis melo L., were analysed on four different host plant species (cotton, melon, sweet potato and Abutilon theophrasti Medic). Comparison with previously published results of similarly treated females reared from sweet potato plants showed performance related differences leading to oviposition. In the present study, the generalized behavioral pathway (walking, host- encounter, antennation, probing and oviposition) did not vary among host plant species for melon- reared parasitoid females. Host assessment by antennation leading to host acceptance for probing varied from 10.5- 12.3 sec among …

Behaviors Of Female Eretmocerus Sp. Nr. Californicus (Hymenoptera: Aphelinidae) Attacking Bemisia Argentifolii (Homoptera: Aleyrodidae) On Cotton, Gossypium Hirsutum, (Malavaceae) And Melon, Cucumis Melo (Cucurbitaceae), David H. Headrick, Thomas S. Bellows, Jr., Thomas M. Perring

Horticulture and Crop Science

Behaviors of Eretmocerus sp. nr. californicus females attacking Bemisia argentifolii Bellows & Perring infesting cotton, Gossypium hirsutum L., and melon, Cucumis melo L., were quantified. Adult female behaviors were described and quantified for Eret. sp. nr. californicus to establish a behavioral time budget analysis. Females readily searched for host whitefly nymphs on cotton leaves with walking speeds averaging 0.5 mm/s. Females remained infrequently on melon leaves; those that did remain and search for hosts averaged walking speeds of 0.33 mm/s. The duration of host assessment by antennation was related to subsequent behaviors. Rejecting a host was a shorter process than …

Succeeding In Law School: A Comparison Of Women's Experiences At Brooklyn Law School And The University Of Pennsylvania, Marsha Garrison, Brian Tomko, Ivan Yip

Michigan Journal of Gender & Law

This Article reports our findings from a replication of the Penn research conducted at Brooklyn Law School in order to test the experience-performance link reported by the Penn researchers. Brooklyn Law School offers an ideal setting for a test of the Penn research because it already has adopted most of the reforms that the Penn researchers believe would reduce women's alienation from the learning environment and thus improve their academic performance. First, Brooklyn Law School, as compared to other American law schools, has a large proportion of women faculty. During the 1994-95 academic year, thirty-seven percent of its tenured and …

Health-Promoting Behaviors: Predictors Of Early Vs Late Initiation To Prenatal Care, Frances Mary Mckeon

UNLV Retrospective Theses & Dissertations

The purpose of this descriptive, quantitative study was to examine factors that could predict a woman's timing of prenatal care initiation. Participation in early prenatal care, a type of health-promoting behavior, has been associated with improved maternal/child health. Many women however, delay prenatal care initiation until late in their pregnancy; Pender's Health Promotion Model and self-reported data were used to examine the relationship between: (a) preconception participation in health-promoting behaviors, (b) demographic variables, (c) situational factors, (d) interpersonal social support, and (e) perceived barriers to/benefits of prenatal care and the timing of initiation to prenatal care. Self-administered questionnaires were completed …

The Effects Of Ecdysis On Feeding Frequency And Behavior Of The Common Garter Snake (Thamnophis Sirtalis), James Robert Turmo

Honors Capstones

Garter snakes were used to study changes in feeding frequency and behavior associated with ecdysis. Feeding and shedding records of a captive snake colony were combined to test for correlations between feeding frequency and shedding. Snakes ate significantly less frequently before shedding than after shedding. Likelihood of eating was lowest when snakes were in the blue-eyed state. Four behaviors; latency to move, strikes at a stationary stimulus, strikes at a moving stimulus, and response distance to an approaching threat were scored while snakes were in the blue-eyed and clear-eyed state. Latency to move, strikes at a moving stimulus, and response …

Nest Material As A Delivery Method For Avicides: Preliminary Tests With African Weaver Finches, Stephen A. Shumake, Peter J. Savarie

Proceedings of the Seventeenth Vertebrate Pest Conference 1996

To evaluate the potential of using nesting material as a medium for avicide delivery, five organophosphates (Dasanit^®, Volaton^®, fenthion, parathion, and Cyanophos^®) were tested on small groups of paired male-female quelea (n = 4 to 9). Toxicants were presented to each pair of birds on five 13-cm strands of cotton string after a preliminary screening for male nest weaving behavior. Tested concentrations ranged from 100% technical grade to 0.003 % compound diluted with acetone. Dasanit^® was found to be the most effective candidate with some lethal effects noted at 0.012%. An optimal concentration …

Bald Eagles Wintering Along The Des Moines River, Iowa, Neil Sabine

Journal of the Iowa Academy of Science: JIAS

Distribution, habitat use, and foraging behavior of Bald Eagles (Haliaeetus leucocephalus) wintering in southeast Iowa were studied in January - March 1990 and November 1990 - March 1991. Eagles were seen from November through March with the highest numbers in January and February. Adults had shorter winter residence times than immatures and they appeared to be less active during the day. Eagles concentrated their foraging efforts along certain river segments where they fed exclusively on fish. Timber harvesting along the river reduced eagle use and is considered to be the most serious threat to sustaining eagle use of the area. …
