Description
The purpose of this study was to develop proposal lesson plans for 4th-6th graders based on active learning to integrate movement physical activity into the curriculum. The 4th-6th graders were chosen, as this is the age where teaching typically transitions from active learning to sedentary/lecture style teaching. Research compiled indicated positive effects of active based learning on children such as increased attention span, retention, and general focus. A survey was created to not only assess the perception of active versus didactic learners, but to also assess the effects of movement-based learning on the variables that research claimed to change. The lesson plans developed here should be transferable to a classroom lesson to evaluate the hypothesized results.

Description
Aging and the menopause transition are both intricately linked to cognitive changes
during mid-life and beyond. Clinical literature suggests the age at menopause onset can differentially impact cognitive status later in life. Yet, little is known about the relationship between behavioral and brain changes that occur during the transitional stage into the post-menopausal state. Much of the pre-clinical work evaluating an animal model of menopause involves ovariectomy in rodents; however, ovariectomy results in an abrupt loss of circulating hormones and ovarian tissue, limiting the ability to evaluate gradual follicular depletion. The 4-vinylcyclohexene diepoxide (VCD) model simulates transitional menopause in rodents by selectively depleting the immature ovarian follicle reserve and allowing animals to retain their follicle-deplete ovarian tissue, resulting in a profile similar to the majority of menopausal women. Here, Vehicle or VCD treatment was administered to ovary-intact adult and middle-aged Fischer-344 rats to assess the cognitive effects of transitional menopause via VCD-induced follicular depletion over time, as well as to understand potential interactions with age, with VCD treatment beginning at either six or twelve months of age. Results indicated that subjects that experience menopause onset at a younger age had impaired spatial working memory early in the transition to a follicle-deplete state. Moreover, in the mid- and post- menopause time points, VCD-induced follicular depletion amplified an age effect, whereby Middle-Aged VCD-treated animals had poorer spatial working and reference memory performance than Young VCD-treated animals. Correlations suggested that in middle age, animals with higher circulating estrogen levels tended to perform better on spatial memory tasks. Overall, these findings suggest that the age at menopause onset is a critical parameter to consider when evaluating learning and memory across the transition to reproductive senescence. From a translational perspective, this study informs the field with respect to how the age at menopause onset might impact cognition in menopausal women, as well as provides insight into time points to explore for the window of opportunity for hormone therapy during the menopause transition to attenuate age- and menopause- related cognitive decline, and produce healthy brain aging profiles in women who retain their ovaries throughout the lifespan.

Description
Childhood obesity is a growing public health concern in the United States. For several years, many interventions have been established to reduce the prevalence of childhood obesity. However, these interventions have not adequately utilized existing models of behavior change, and as a result, have been unsuccessful in increasing levels of physical activity and healthy dietary intake. One such model of change, the Transtheoretical Model, views behavior change as occurring through a series of stages with progression through the stages being facilitated by cognitive and behavioral processes. Within these processes the constructs of consciousness-raising, helping relationships, and self-efficacy have been shown to be most influential in changing behaviors. Thus, the objective of this paper is to evaluate the effectiveness of such constructs and establish a multi-faceted approach to combat this epidemic.

Description
Children's wellbeing has been of utmost concern to society, and recently this topic has taken a particular focus in both health and achievement. As the focus shifts towards promoting a healthier and more academically successful youth, the relationship between the two warrants investigation. Specifically, the relationship between physical fitness and academic performance (i.e. grades) in 4th grade students was assessed. A cross-sectional design was used to assess physical fitness of children (M=9.39 years) by means of the FITNESSGRAM assessment tool. Third-quarter grades were used to measure academic performance. Relationships between the variables were determined through bivariate plots, Pearson product moment correlation analysis, independent t-tests, and a three-step regression analysis. The results show a significant relationship between students' aerobic fitness and academic performance. Furthermore, the findings of this study suggest incremental validity between aerobic fitness and academic performance, thus implying predictive value associated with increased physical fitness and academic achievement.

Description
Many high school students demonstrate an overall lack of interest in science. Traditional teaching methodologies seem to be unsuccessful at engaging students \u2014 one explanation is that students often interpret what they learn in school as irrelevant to their personal lives. Active learning and case based learning methodologies seem to be more effective at promoting interest and understanding of scientific principles. The purpose of our research was to implement a lab with updated teaching methodologies that included an active learning and case based curriculum. The lab was implemented in two high school honors biology classes with the specific goals of: significantly increasing students' interest in science and its related fields; increasing students' self-efficacy in their ability to understand and interpret the traditional process of the scientific method; and increasing this traditional process of objectively understanding the scientific method. Our results indicated that interest in science and its related fields (p = .011), students' self-efficacy in understanding the scientific method (p = .000), and students' objective understanding of the scientific method (p = .000) statistically significantly increased after the lab was administered; however, our results may not be as meaningful as the p-values imply due to the scale of our assessment.

Description
In females, critical hormonal shifts occur during puberty, menstruation, pregnancy, and <br/>menopause. The fluctuating ovarian hormone levels across a woman’s lifespan likely contribute <br/>to inflammatory responses driven by the immune system, which is regulated by a variety of <br/>physiological pathways and microbiological cues. Pregnancy in particular results in drastic <br/>changes in circulating hormone profiles, and involves a variety of physiological changes, <br/>including inflammatory responses of the immune system. There is evidence that these effects are <br/>mediated, in part, by the significant hormone fluctuations that characterize pregnancy and <br/>postpartum periods. This thesis highlights and synthesizes important physiological changes <br/>associated with pregnancy, and their potential implications on cognitive and brain aging in <br/>women. A tertiary model of cognition is presented depicting interactions between hormonal <br/>history, reproductive history, and immune functions. This research is important to create a better <br/>understanding of women’s health and enhance medical care for women throughout pregnancy <br/>and across reproductive hormone shifts across the lifespan.

Description
The relevance of depression in the clinical realm is well known, as it is one of the most common mental disorders in the United States. Clinical depression is the leading cause of disease for women worldwide. The sex difference in depression and anxiety has guided the research of not just recent studies but older studies as well, supporting the theory that gonadal hormones are associated with the mechanisms of emotional cognition. The scientific literature points towards a clear correlative relationship between gonadal hormones, especially estrogens, and emotion regulation. This thesis investigates the neural pathways that have been indicated to regulate mood and anxiety. Currently, the research points to the hypothalamic-pituitary-adrenal axis, which regulates the stress response through its ultimate secretion of cortisol through the adrenal cortex, and its modulated response when exposed to higher levels of estrogen. Another mechanism that has been investigated is the interaction of estrogen and the serotonergic system, which is noteworthy because the serotonergic system is known for its importance in mood regulation. However, it is important to note that the research seeking to determine the neurobiological underpinnings of estrogen and the serotonergic system is not expansive. Future research should focus on determining the direct relationship between cortisol hypersecretion and estrogens, the specific neurobiological effects of serotonergic receptor subtypes on the antidepressant actions of estrogens, and the simultaneous effects of the stress and serotonergic systems on depressive symptoms.

Description
Progestogens, such as progesterone (P4), medroxyprogesterone acetate (MPA), and micronized progesterone (mP4), are given to ovary-intact women during the transition to menopause to attenuate heavy uterine bleeding and other symptoms. Both progesterone and MPA administration have been shown to impair cognition in ovariectomized (Ovx) rats compared to vehicle-treated controls. mP4, however, has yet to be investigated for cognitive effects in a preclinical setting. Further, progestogens affect the GABA (-aminobutyric acid) ergic system, specifically glutamic acid decarboxylase (GAD) the rate limiting enzyme necessary for synthesizing GABA. The goal of this experiment was to investigate the cognitive impact of P4, MPA, and mP4, in an ovary-intact transitional menopause model using 4-vinylcyclohexene diepoxide (VCD) and assess whether these potential changes were related to the GABAergic system. One group of rats received vehicle injections, and the remainder of the groups received VCD to induce follicular depletion, modeling transitional menopause in women. Vehicle or hormone administration began during perimenopause to model the time period when women often take progestogens alone. Rats then underwent testing to assess spatial working and reference memory in the water radial-arm maze (WRAM) and spatial reference memory in the Morris water maze (MWM). Results indicate that P4 and MPA improved learning for working memory measure, but only MPA impaired memory retention in the WRAM. For the WRAM reference memory measure, VCD only treated rats showed impaired learning and memory retention compared to vehicle controls; progestogens did not impact this impairment. Although GAD expression did not differ between treatment groups, in general, there was a relationship between GAD expression and WRAM performance such that rats that tended to have higher GAD levels also tended to make more WRAM working memory errors. Thus, while P4 and MPA have been previously shown to impair cognition in an Ovx model, giving these hormones early in an ovary-intact perimenopause model elicits divergent effects, such that these progestogens can improve cognition. Additionally, these findings suggest that the cognitive changes seen herein are related to the interaction between progestogens and the GABAergic system. Further investigation into progestogens is warranted to fully understand their impact on cognition given the importance of utilizing progestogens in the clinic.

Description
Previous research has determined that sentence comprehension is affected when taxing an individual’s cognitive resources, such as attentional control and working memory. This can be done by manipulating the prosody of simple and complex sentences, by allowing irregular rhythm and pitch changes to occur within speech. In the present thesis, neurotypical adults were asked to comprehend sentences with normal and monotone prosody in three different versions of a sentence-picture matching task. A no-load version served as a control with the other two taxing cognitive resources in these individuals. In addition, individuals completed four other tasks that are known to reliably measure working memory. Our results indicate a possible relationship between high accuracy in complex sentences spoken in a monotone prosody with working memory when time restraints are placed on individuals. Collectively, these results may lead to a new way of working with individuals in speech therapy who have suffered a stroke by better understanding the cognitive resources that are taxed in different types of sentence comprehension settings.

Description
Resistance training is a modality of exercise that has grown in popularity over the past two decades, particularly for its role in improving muscular fitness by increasing muscular strength, power, and hypertrophy. Due to this increase in demand, more and more people are entering the gym for their first time and eager to learn about the ways to get bigger and stronger as fast as possible. The aim of this summary is to provide evidence-based information that resistance trainers or fitness personnel can use to design an effective training program. In order to optimize your resistance training protocol there are three main areas to focus on: increasing volume, managing intensity, and active recovery.
