Effects Of Illustrations On Retention And Visual Attention Using Authentic Textbooks, Loris P. Fagioli

Master's Theses

Problem

The purpose of this exploratory study was to validate a model of multimedia learning, incorporating learner-specific characteristics such as intelligence, memory, and measures of visual attention.

Method

The sample consisted of 62 Andrews University students (26 males, 36 females, and mean age 21.7). Data were gathered by means of standardized testing (RPM, WAIS- III) and eye-tracking. MLR was used to determine significant visual attention predictors for retention and SEM was used to test a hypothesized model of multimedia learning.

Results

Multiple Linear Regression was significant (p.05; GFI = .923; CFI = .986; RMSEA = .043; PGFI = .451) proving …

Lipid Productivity Of Algae Grown On Dairy Wastewater As A Possible Feedstock For Biodiesel, Ian C. Woertz

Master's Theses

The objective of this thesis is to develop a biological wastewater treatment system that utilizes algal growth to simultaneously create renewable energy in the form of biodiesel and digester biogas, remove polluting nutrients, and abate greenhouse gases. Research under the Department of Energy Aquatic Species Program during 1978-1996 concluded that cultivating algae for biofuels was cost prohibitive at that time and that an integrated approach should be studied that combined wastewater treatment with algal biofuel production. Nutrient removal, in particular nitrogen and phosphorus, from wastewater is a growing regulatory need and the use of algae cultivation could create a unique …

Motherhood, Memory And Aging : Object Recognition Performance, Julia Margaret Friedenberg

Master's Theses

Reproductively experienced female rats have been shown to have attenuated stress responses, improved visual systems, and better memory and learning. This study sought to extend those findings by comparing aged reproductively experienced and aged virgin female rats on an object recognition task, as well as comparing levels of corticosterone and 17p-estradiol and neural activation. Multiparous (MP, 2 reproductive experiences) females performed better on the task and demonstrated quicker habituation to the task than nulliparous (NP, no reproductive experiences) females. No hormonal or neural activation differences were found. The present study contributes to the growing research areas of reproductive experience and …

The Impact Of Positive Reinforcement And Noncash Rewards: A Study Of How Its Implementation Can Affect An Employee's Level Of Motivation And Performance, Michael Benjamin Young

Master's Theses

The most powerful forms of motivation cost little or nothing at all. Though nominally effortless, the proper rewarding of excellent performers has become sorely underutilized. As a result, employees are feeling less appreciated and becoming more unmotivated. A review of the literature found three reverberating observations: it is a fallacy that money motivates; recognition, such as positive reinforcement and praise motivate; and tangible, low-cost, noncash rewards can motivate. The anecdotal data in this current research tends to support the salient findings provided by scholarly researchers. Additionally, this current research aims to illuminate the pressing need to make a more concentrated …

Fecundity And Survival Of The Calanoid Copepod Acartia Tonsa Fed Isochrysis Galeana (Tahitian Strain) And Chaetoceros Mulleri, Angelos Apeitos

Master's Theses

Historically, red snapper (Lutjanus campechanus) larviculture at the Gulf Coast Research Lab (GCRL) used 25 ppt artificial salt water and mixed, wild zooplankton composed primarily of Acartia tonsa, a calanoid copepod. Acartia tonsa was collected from the estuarine waters of Davis Bayou and bloomed in outdoor tanks from which it was harvested and fed to red snapper larvae. We are developing a more controlled copepod mass culture system to support finfish larviculture. To that end, I examined the effect of single species versus mixed species of algae as food for the copepods. Wild A. tonsa were isolated and reared in …

Shrines And Prayers: Two Missing Elements Of Comprehensive Mass Fatality, Rhonda Keyes Pleasants

Master's Theses

As a Licensed Funeral Service Provider, I am aware of the special issues which surround mass fatalities. A study of numerous mass fatality plans yielded identification of two missing elements from most plans which are critical to mass fatality management. The first missing element is ritual used in the respectful treatment of the dead. The second missing element is religious precepts regarding caring for and final disposition of the dead based upon the particular belief system of the deceased, their family, surrounding community, and culture. Specific qualitative methods of research used were a review of the professional literature, identification of …

Learned Fear And Reaction To Novel Stimuli: Behavioral And Hormonal Stress Responses In The Maternal Rat, Brandi Nicole Rima

Master's Theses

The present thesis examines the relationship between reproductive experience and the behavioral, neural, and hormonal processes of learned fear in the female rat. Multiple research models indicate that reproductive experience functions to decrease the female's stress response in potentially harmful environments, thus providing her with numerous survival benefits, including decreased fearfulness, increased aggression, and refined hunting skills. Based on existing understandings of maternal experience and unconditioned fear, this study was designed to determine how nulliparous (no reproductive experience, NP), primiparous (one reproductive experience, PP) and multiparous (more than one reproductive experience, MP) rats comparatively respond to a Pavlovian paradigm of …

From The Pixels Up : Processes And Procedures In The Construction Of A Neural-Site Geographic Information System, Christopher John Mason

Master's Theses

This study examines the question, is it possible to develop a neutral-site Geographic Information System (GIS) that addresses information needs useful for the training of emergency management personnel? To answer this question a subordinate question requiring an answer is what specific steps are required to accomplish this goal? As a base for the data provided here, the history of cities as an initial root of civilization and the concept of emergency management are discussed. Direct intersections, where the specific applications of emergency management technology provide real benefits to local governmental organizations, such as those at the city level are also …

"King Harvest (Has Surely Come)" : Rural Populist Imagery In Roots Rock Music, 1967-1973, Christopher Lee Witte

Master's Theses

Through a detailed focus on these five groups and their music, with an added emphasis on their lyrics, this thesis attempts to create a meaningful tie between Slotkin' s study of American myth-making and story creation with a key area of popular culture - music - that he did not focus on. The thesis itself is separated into three key chapters - the first reveals how nature and landscape are presented in these songs and how they viewed modern twentieth century America with idealized notions of a rural past. The second discusses their presentations of heroes and anti-heroes as musical …

The "Cosmic Covenant" In The Letter To The Hebrews, Jeffrey P. Walker

Master's Theses

The Topic The "cosmic covenant" in Hebrews reflects three main ideas: There exists a close affinity between the letter and Enochic Judaism; the letter is a product of Roman Gentile Christianity that emerged as a response to Jewish particularists in the Second Temple covenantal debate; and the writer's cosmic perspective had the simultaneous effect of supplanting and universalizing the Jewish covenantal concept. The Purpose The thesis offered here is that Hebrews presupposes a notion of "cosmic covenant" similar to that found in Enochic Judaism. Conclusions What has emerged is support for how the universalistic scope of 1 Enoch and its …

Eliciting Facial Expressions In Children With And Without Down Syndrome, Orietta Coz

Master's Theses

This study investigated facial expressions of children between the ages of 10 and 15 years with Down Syndrome (experimental group) and compared them to typically developing children (control group). Elicitation of facial expressions was carried out through showings of video clips. Trained observers were used to code expressions of happiness, anger, and disgust from video recordings that were made of the children’s reactions while they watched the video clips.

I hypothesized that Down Syndrome children will not differ from typically developing children in the frequency of elicited happy expressions. However, I expected them to differ in the frequency of elicited …

Sentence Recognition In Native And Foreign Languages : Comprehension Of Form And Meaning, Sara Elizabeth Sepanski

Master's Theses

The goal of language comprehension is to retrieve and retain the meaning of speech or text. Research with monolinguals has shown that participants' ability to detect structural changes in sentences decreases with time, while their ability to detect meaning changes remains accurate (Sachs, I967). In this study I examined whether this monolingual pattern holds for bilingual speakers in a second language. English-Spanish bilinguals at three different proficiency levels participated in a reading task in which native (LI) and non-native (L2) language sentences were presented. Participants read both LI and L2 sentences and were then tested for their recognition of the …

A Study On Donor Preferences And Charitable Giving, Stephanie Roderick Williams

Master's Theses

This study entailed the administration of a mail survey of 2,000 donors to determine if baby boomers (aged 40 to 58) would be more inclined than mature donors (aged 59 and older) to value efficiency, organizational outcomes, and information when making a charitable gift. There were no statistically significant differences between donors of the baby boomer generation and mature donors concerning the variables efficiency and outcomes, but there were statistically significant differences between baby boomers and mature donors regarding the variable information: baby boomers valued information more than mature donors did.

Moreover, significant differences were found between young donors (aged …

Cytokine Expression By T. Helper Cells Responding To Stress, Dina Zanetti

Master's Theses

Stress causes alterations to the immune system. These alterations have lead to increased susceptibility to antigens. The present study explores shifts in T helper (TH) cell balance (TH1 and TH2), through their cytokine expression. This study was performed in three phases, and focused mainly on animals subjected to a 10 day a chronic unpredictable stress paradigm. Phase one used ELISAs to confirm the cytokine profile produced from TH 1 and TH2 murine cell-lines. Phase two used SDS PAGE and Western Immunoblotting to show that splenocytes from Long Evan's Hooded rats subjected to the stress paradigm, had decreased in intercellular in …

The Life-Long Diminution Of Anxiety Response As A Consequence Of Reproductive Experience, Ilan M. Mcnamara

Master's Theses

Reproductive experience (RE), associated with hormonal fluctuations and enriching environmental stimuli, enhances spatial memory and blunts responses to stress/anxiety. Whereas stress reductions occur during lactation, the persistence of the RE-anxiolytic effects is unclear; and little research has focused on the HP A axis, amygdala, and other anxietyrelated areas. Using an elevated plus maze (EPM), we examined anxiety in nulliparous (NP), primiparous (PP), and multiparous (MP) females (zero, one, or two litters, respectively) at 6, 10, 14, 18, and 22 months of age. Brains were subsequently analyzed for neurodegeneration in dorsal raphe nucleus (DRN). RE significantly dampened anxiety (defined by time …

The Status Of Leptodactylus Validus As A Single Taxon And Its Relationship To Letptodactylus Pallidirostris, Kenneth Christopher Yanek

Master's Theses

Leptodactylus validus exhibits an unusual distribution inhabiting Trinidad, Tobago, and the Lesser Antilles, but not the mainland of South America. This distribution is inconsistent with other distribution patterns observed for these islands. Although slight variation in adult morphology has been observed among the island populations, call data suggest the presence of a single species. Calls of Leptodactylus pallidirostris from Venezuela suggested that this taxon might be conspecific with L. validus. Herein sequence data from the 12S and 16S mt rRNA genes were collected and analyzed in order to address: 1.) whether more than one species is represented within L. validus, …
