Stage Managing The Tempest
No full textThe project will show the process of stage managing The Tempest from start to finish, and the effort required to stage manage a full production. Stage management is the organization and coordination of actors, production staff, designers for the set, lights, sound, and costumes, among others, and crew members to successfully create a theatre production. This involves running meetings between the various designers, recording information, such as useful notes for the designers not in attendance as well as blocking notes for the actors, at rehearsals, and running the show once it opens. This is referred to as “calling the show”, which involves giving cues for light transitions and sound effects to the operators of the light and sound boards, and may also include cues for projections or set movement. Notes and the script with cues marked are held in a large prompt book which represents the culmination of the stage manager’s work
The Effect of Creatine Monohydrate on Male Ice Hockey Players’ Skating Sprint Speed
No full textFree creatine is a protein-like substance that is synthesized in the body and can be ingested by consuming animal products such as meat or fish. It utilizes the enzyme creatine kinase to create phosphocreatine, which, in turn, produces ATP, the body’s energy source. The phosphocreatine system is key for providing energy during short, high-intensity exercise, which is equivalent to a shift during an ice hockey game. Few studies exist that have examined the effect of creatine ingestion on ice hockey skating performance, yet the intake of creatine monohydrate may increase the sprint speed of hockey players after a 5-day “loading phase”. Eleven Hope College ice hockey players participated in 3 repeated 70-foot skating sprints with 2 minutes of rest between each sprint. Participants were then assigned into either a creatine group (n=7) or a placebo group (n=4). The week after the pretest, participants ingested the assigned supplement 4 times a day for 5 days. Each dose contained 5 grams of creatine or 5 grams of placebo along with 8 ounces of gatorade. After the “loading phase” the participants performed a posttest, which followed the same protocol as the pretest. Positive results would allow hockey teams to use creatine supplementation to increase players’ sprint speed as well as decrease the amount of rest time needed to be able to perform another maximal shift
The Effect of Directing Groups on the Rate of Rhodium-Catalyzed Decarbonylation Reactions
No full textCarbon-carbon bonds are difficult to activate due to the lack of flexibility of the sigma bonds and steric hindrance which contribute to the stability of the bond. However, the addition of a rhodium catalyst allows for decarbonylation of aryl ketones via carbon-carbon single bond activation. The decarbonylation process is essential to determine the effectiveness of the directing group. Herein, we describe the synthetic pathways for the starting materials, as well as the effects of various nitrogen containing directing groups on the rate of decarbonylation
The Effects of Foam Rolling on Vertical Jump and Flexibility in Division III Female Power Athletes
No full textCertain types of stretching have been shown to decrease muscular power in the lower extremities. Foam rolling is a form of self-myofascial release that helps to stretch and evenly realign muscle fibers. Previous research has suggested that foam rolling not only increases flexibility and ROM but does so without the subsequent decrease in power output. In fact, recent research has shown that foam rolling may even improve muscular power output among certain athletes. Therefore, the purpose of this study is to examine the effect of three different warm-up conditions on flexibility and vertical jump in a group of athletes whose sport involves explosive muscular power. Hope College female track athletes (sprinters and high jumpers), volleyball and basketball players were recruited for this study. Participants engaged in one familiarization session and three testing sessions: A) A stationary cycling warm up which consisted of four minutes of cycling at 50 rpm on a Monark Cycle Ergometer, B) A dynamic warm up which consisted of eight minutes of lower body dynamic stretches and C) The foam rolling condition which included two sets of 30 seconds of rolling on each leg addressing the gluteal, hamstrings, quadriceps, and calve muscles. Each session occurred 72 hours apart from one another. Participants were randomly assigned their testing condition order and served as their own control. Each condition session measured vertical jump height on a vertical jump mat, sit and reach flexibility, and knee and ankle range of motion. Significant results would allow foam rolling to be recommended as an effective mode for warm up immediately prior to events in which power output plays a vital role. This study is ongoing, and results will be available during the poster celebration
The Psychology of Politics
No full textThe research will analyze the relationship between political participation and patterns of voting behavior. Political participation will be assessed through political involvement and knowledge of government policies. Participation can be reflected or assessed in looking at individual voting patterns and behaviors. The study will assess how attitudes influence individual voting preferences and different patterns of voting behavior, assessing why people vote the way they do. Individuals with stronger party affiliation will have a higher level of political participation or involvement. These individuals will also have a higher rate of voter turnout overall. The study will look at how emotion and cognition drive political attitudes that influence their voting preferences. The research will further assess how knowledgeable people are of governmental policies. The research will emphasize the impact of public opinion that drives government policies and will address what has been done to increase political participation and voter turnout in upcoming elections
Wildlife Use Patterns in a Constructed Wetland
No full textWildlife land use patterns were monitored from January 2015 through April 2016 at ten sites near the West Michigan Regional Airport before, during, and after conversion of agricultural land to a mitigation wetland by the Outdoor Discovery Center/Macatawa Greenway. Due to concerns about potential collisions between aircraft and wildlife attracted to the restored wetland, point count surveys and trail cameras are being used to track changes in bird and mammal abundance in various habitats around the airport. Based on published studies of hazards to aircraft, animals were grouped into four impact categories: deer, high impact animals, low impact animals, and small mammals. Changes in animal abundance were compared among sites representing open water, the restoration construction site, existing wet meadow, and airport property while correcting for extreme seasonal variation. Sites with open water were found to have higher abundance of animals than either the wetland construction site or the airport property. Overall, there were significant differences in abundance among the different sites for both high impact animals and small mammals, but these differences are generally overwhelmed by seasonal variation. The existing wet meadow site showed high variation in abundance of animals in all four impact categories, but generally those abundances were not significantly different from wildlife abundance in the other monitored habitats. Wildlife monitoring is expected to continue for the next two years to enable documentation of post-restoration changes, as well as to establish baseline data on the seasonality of wildlife use at all sites
Effect of Varying Velocity on Post-Activation Potentiation of Vertical Jump Performance
No full textPost-activation potentiation (PAP) is a phenomenon where muscle performance is enhanced after a bout of high-intensity activity. Minimal research has been conducted on varying velocities of contraction and its effect on PAP. Discovering optimal conditions for PAP will benefit athletes in explosive sports. This study was designed to determine if different velocities of leg press at 70% of one repetition maximum (1RM) improved vertical jump performance on the Vertek® and Just Jump Mat®. It was hypothesized that faster leg press velocities would improve vertical jump more than slower leg press velocities. Twenty Hope College students (13 females, 7 males) participated in seven randomly assigned testing sessions (~ four weeks duration). The testing days consisted of a familiarization, two baseline, and four testing days. Testing days consisted of a warm up, five unilateral leg presses at 70% 1RM at assigned velocity and a six-minute rest followed by three jumps on the Just Jump Mat or Vertek. Each participant completed each velocity for each jump condition. There was no significant improvement between the pretests and subsequent velocity tests when measured by the Vertek (p=0.462) or mat (p=0.732). Mean VJ height for females for initial (16.2±1.72), fast (16.4±1.68) and slow (16.5±1.69) conditions showed no significant difference. Mean VJ height for males for initial (22.2±2.70), fast (22.0±2.81) and slow (22.4±2.86) conditions showed no significant difference. There was a highly significant correlation between the Vertek and mat results (r =0.941, p\u3c 0.01), validating the jump mat as a legitimate measure for vertical jump. Limitations include study design, participant commitment, type of participant and type of leg press routine. Future studies should include manipulation of contraction velocity, rest intervals, and percentage of 1RM along with subjects
Predicting Closeness Behaviors: Additional Validation of the Unidimensional Relationship Closeness Scale
No full textThe Unidimensional Relationship Closeness Scale (URCS; Dibble, Levine, & Park, 2012) was introduced as a self-report measure of relationship closeness. This research seeks to provide additional evidence for the construct validity of the URCS. After completing the URCS and other leading measures of closeness, participants will be randomly assigned to hold a short conversation with a friend or a stranger. If the URCS is measuring relational closeness, then it should predict behavioral outcomes associated with closeness such as physical distance between conversation partners and amount of eye contact. Moreover, we seek to learn whether the URCS will outperform the leading alternative measures. Results will inform better measurement of relationship closeness
Exploring the Role of xCT in Neurore-generation through Laser Ablation of Zebrafish Neurons
No full textSystem xc– is a heterodimeric amino acid transporter comprised of a light chain unit, xCT, which confers the transport specificity, and a heavy chain unit, 4F2hc. System xc– has been shown to facilitate the exchange of intracellular glutamate for extracellular cystine, which is rapidly reduced within the cell to cysteine, the limiting reagent for glutathione (GSH) production. GSH is an endogenous reducing reagent that is important in mitigating the oxidative stress that, untreated, can trigger cell death. It has been shown that system xc– is strongly expressed in the central nervous system, particularly in activated neuroprotective cells such as astrocytes and glia. It is believed that relief of oxidative stress in the environment of neurons and their protective counterparts is critical in processes such as neuroregeneration. The thrust of the current study is to identify the role that xCT plays in neuroregeneration in vivo using femtosecond laser ablation to initiate apoptosis, followed by neuroregeneration. Initial results will be presented including expression patterns of the xCT gene in developing zebrafish and preliminary examples of laser ablation
A [REDACTED] Dictatorship
No full textNorth Korea has had a history of dividing and obscuring itself from the rest of the world, while advocating the creation of weapons and military advancements. The rest of the world has kept an eye trained on the activities of North Korea, measuring their accomplishments and abilities, and at times making them unsure about North Korea’s actions. Over time, as technology has improved, North Korea has begun to control its citizens’ access to media and implementing punishment measures. The control of all media within their country, and the tight hold on media that enters and exits North Korea, has affected other countries and their perception of North Korea. In turn, nations have tried to comprehend their actions and find ways to help the North Korean people while still benefiting themselves
