Literature Review of Nosocomial Infections Passed Through Nurses' Personal Items
Corina Hickman
As defined by the encyclopedia, nosocomial infections are infections whose development is favored by a hospital environment, such as one acquired by a patient during a hospital visit or one developing among hospital staff. There has been more of a prevalence of hospital-acquired infections that are linked directly to medical personnel – especially nurses. Nurses have the most contact with patients and are potentially putting patients at highest risk for nosocomial infections. Even though nurses are following isolation precautions and standard hand washing in between patients; there are still a few things on nurses that could be harmful to their patients including stethoscopes, uniforms, and cell phones. I will be looking at research studies that show how harmful these personal items on nurses can be for patients, and what protocols are implemented in hospitals to keep patients safe from acquiring any nosocomial infections.

Cytotoxicity Studies of Fijianolide (a.k.a. Laulimalide) Acetylated Derivatives Against Pancreatic Cancer Cell lines to Investigate New Paths For Therapeutic Development
Tyler A. Johnson, David Coppage, Nicole L. McIntosh, Colon V. Cook, Frederick A. Valeriote, and Phillip Crews
Opioid receptors belong to the large superfamily of seven transmembrane-spanning (7TM) G protein-coupled receptors (GPCRs). As a class, GPCRs are of fundamental physiological importance mediating the actions of the majority of known neurotransmitters and hormones. The Mu (µ), Delta (δ) and Kappa (MOR, DOR, KOR) opioid receptors are particularly intriguing members of this receptor family as they are the targets involved in many neurobiological diseases such as addiction, pain, stress, anxiety, and depression. To date few marine natural products have been investigated for their neurobiological activities.1 One noteworthy example involves ziconotide (1) from the cone snail Conus magnus.2 Compound 1 was the first marine natural product approved by the FDA and is used for the treatment of pain, marketed under the trade name Prialt® (2004).3 More recently Hamman reported that aaptamine (2) is the first marine natural product to show in vivo anti-depressant activity, however no mechanism of action was proposed.1,4 During a separate collaborative screening project we profiled 96 sponge-derived extracts and discovered that demethyl–aaptamine (3) and demethyl (oxy)–aaptamine (4) were selective DOR agonists using an LC-MS based library of an active methanolic extract coll. no. 92553 FM as shown in Fig. 1. We speculated that the in vivo activity for 2 could thus be linked to the DOR target and to test this hypothesis we conducted the following experiments below.

Examining the Validity of the Preschool Kitchen Task Assessment : An Exploratory Study
Christine Kim and Angelica Soltis
Executive functioning (EF) helps build a strong foundation for school readiness, play development, and social participation in children. EF includes attention, inhibitory control, working memory, emotional regulation, planning, and problem solving
Currently, there are few ecologically valid assessments that measure EF in children. The purpose of this exploratory research study was to validate the Pre-school Kitchen Task Assessment (PKTA) as an ecological tool to assess EF in preschool age children. The PKTA utilizes an age appropriate art craft activity and a standardized scoring system to determine the level of assistance (cues) each child needs to complete each step of the craft activity. This study compared the scores from the PKTA to the scores from established neurological assessments, specifically, BRIEF-P (preschool version), the Forward and Backward Digit Span and the Dimensional Change Card Sort in 24 typically developing children ages 3 to 5 living in Marin County, California. No significant correlation was found between the results of the PKTA and the neurological assessments used in this study. However, it was confirmed that the PKTA was sensitive to age in months. As the PKTA is sensitive to age, researchers suggest that the PKTA may be a useful developmental tool in assessing important skills such as fine motor, organization, visual- perception, and judgment and safety in preschool age children.

The Lifestyle-integrated Functional Exercise Program for Older Adults
Jessica Lim, Courtney Beyer, Anna Lee, and Sienna Anderson
According to the Centers for Disease Control and Prevention, falls are the most common cause of fatal and non-fatal injuries among older adults over the age of 65 (Centers for Disease Control and Prevention [CDC], 2009). Falls can lead to a myriad of traumatic physical and emotional consequences. Integrated exercise programs such as the Lifestyle-integrated Functional Exercise (LiFE) program are effective in preventing falls and increasing fall efficacy in individuals who have previously fallen (Clemson et al., 2012). The purpose of our study was to examine if the LiFE program is as effective in reducing fall risk and increasing fall efficacy for non-fallers as it is for fallers. Due to a small sample size of three older adults residing in two independent living residential facilities, the results from our study are inconclusive. The results show that participants were able to increase or maintain their physical fitness and fall efficacy, as well as make improvements in their balance. Moreover, the participants’ testimonials and progress forms collected six-months after the beginning of the program indicate that the LiFE program may have been effective in allowing integration of balance and strengthening exercises into habits occurring in daily activities.

Handwriting and Metacognition: The Relationship Between Self-Reflection and Penmanship
Rachel E. Malmquist, Chelsey M. Robinson, Kirsten L. Rogers, and Andrea B. Sosa
The majority of school-based occupational therapy (OT) referrals are for handwriting. In fact, fine motor and handwriting concerns affecting educational performance make up 80-85% of OT referrals in schools. Occupational therapists use an abundance of interventions for remediating handwriting difficulties, but there is scant evidence of why specific strategies or combinations of strategies are effective.
Cognitive interventions have shown to be successful in the treatment of handwriting. Metacognitive skill, a component of cognition, allows a child to self-monitor and self-reflect on his or her handwriting skills to correct mistakes and generate goals for improvement. Therefore, a child’s ability to self-reflect on handwriting is likely an important factor when strengthening the learning and use of handwriting. Having insight into a child’s reflection of his or her handwriting abilities will also assist occupational therapists in creating an appropriate and effective handwriting intervention. This study aims to contribute to the evidence regarding the development and treatment of handwriting skill in elementary school-aged children.

Scale Up Isolation of Aaptamine for In Vivo Evaluation Indicates Its Neurobiological Activity is Linked to the Delta Opioid Receptor
Nicole L. McIntosh, Eptisam Lambu, Laura Millan-Lobo, Fei Li, Li He, Phillip Crews, Jennifer L. Whistler, and Tyler Johnson
Opioid receptors belong to the large superfamily of seven transmembrane-spanning (7TM) G protein-coupled receptors (GPCRs). As a class, GPCRs are of fundamental physiological importance mediating the actions of the majority of known neurotransmitters and hormones. The Mu, Delta, and Kappa (MOP, DOP, KOP) opioid receptors are particularly intriguing members of this receptor family as they are the targets involved in many neurobiological diseases such as addiction, pain, stress, anxiety, and depression. Recently we discovered that the aaptamine class of marine sponge derived natural products exhibit selective agonist activity in vitro for the DOP versus MOP receptor. Our findings may explain reports by others that aaptamine demonstrates in vivo anti-depressant effects in mouse models using the Porsolt Forced Swim Test. This project involved the extraction of the sponge Aaptos aaptos (a source of 1), establishing a scale up purification procedure to provide sufficient amounts of 1 (30 mg) for a follow up in vivo evaluation and ultimately confirmation of the structure of 1 using LC-MS and 1H NMR. The results our purification scheme, chemical analysis and in vivo evaluation of 1 using the Marble burying test in rodents are reported here in and suggest that the in vivo anti-depressant effects of 1 are linked directly to its agonist effects on the DOP receptor.

Interprofessional Collaboration Between Occupational Therapists and Registered Nurses in Acute Care Settings: An Exploratory Study
Vincent P. O'Brien, Bethany J. Loy, Kelly Nguyen, and Holly Micheff
Background. Collaboration between occupational therapists and nurses is key to a positive prognosis for their patients. Currently, there is a gap in the research on professional relationships between occupational therapists and registered nurses in acute care settings. Purpose. To examine interprofessional collaboration between registered nurses and occupational therapy in an acute care setting. Methods. A phenomenological, qualitative design with use of semi-structured interviews was used. Interviewees were four occupational therapists and four registered nurses who currently work in acute care settings in Northern California and were recruited through a snowball, convenience and purposive sampling. Themes and subthemes that emerged from the data answered the research questions. Findings. The key factors preventing collaboration were: Time constraints, role confusion and overlap, personality factors, and lack of occupational therapy advocacy. Implications. This study may guide the development of interprofessional education to improve the collaborative relationship between occupational therapists and nurses to ultimately improve quality of care.

Preventing and Reducing Falls in Assisted Living Facilities: An Educational Intervention
Raquel F. Ramos, Jennifer A. Borcich, and Taylor S. Wong
As the number of older adults continues to rise, falling in older adults has become a national health care issue. Many older adults who fall reside in assisted living facilities. Every time a fall incident occurs, first responders are called, utilizing a significant amount of first responder’s time and resources. Therefore, the purpose of this project was to implement a fall prevention program for residents of an assisted living facility (ALF) to reduce fall risk and fall-related calls to the local fire department. The project consisted of a four-week course given once weekly for 60 minutes to residents at an ALF. Course content was evidence-based and included information on the role of occupational therapy in fall prevention, strength and balance exercises, environmental fall risks, and how hydration, nutrition, vitamin D intake, bone health, and medication management impact fall risk. Feedback was overwhelmingly positive, indicating that participants found the information helpful and relevant. Occupational therapists and other health professionals can play an important role in the education of residents and staff of ALFs to increase awareness of fall risks, promote health and well-being among older adults, and help decrease fall-related calls to first responders.

The Left Bank Brasseries: The Evolution of a French-Inspired Restaurant
John A. Sansone
Due to the high failure rates of restaurants in the United States, many studies have come up with various reasons to explain the underlying causes of such a phenomenon. One key study by Parsa (2005) suggests, “Restaurant failures have been attributed to economic and social factors […]” and “Restaurant failures can be studied from economic, marketing, and managerial perspectives.” In particular, lack of capital is a major contributing factor for restaurants failure and researchers agree that a restaurant without a sufficient amount of capital will not survive because of three major expenses: overhead, labor, and food cost. Today’s service industry is indeed categorized by financial distress and this is very visible among owners and operators everyday. However, accurate and consistent internal management decisions may allow a restaurant to maintain financial stability. Managing and developing strong customer relationships overtime can help create a loyal following and that can translate into healthy and sustainable growth for the business.
What roles do internal management practices and external market factors play in achieving sustainable success in the fine-dining restaurant industry? This research study will attempt to unveil how Left Bank Brasseries, a well-respected restaurant in Northern California, have sustained its success for twenty years. Using primary data collected from the management team in the form of interviews, this paper will identify the core competencies of the company and how it navigated this highly competitive landscape over the years. Particular attention will be paid to its financial performance, management practices, and levels of customer satisfaction and how these are related to the restaurant’s brand, which is essentially modeled on the French cuisine but managed the American way.

The Effect of Therapeutic Listening(R) on Bilateral Coordination
Emily Smiley, Daryl Arora, Jiawen Liang, and Melissa Ramirez
This study concludes a 2-year long randomized control pretest posttest design study examining the effects Therapeutic Listening® Bilateral Quickshift intervention, on bilateral coordination in typically developing children between the ages of seven to eleven. Participants were recruited from after school programs at Coleman Elementary and St. Anselm School located in Marin County, California, as well as word of mouth from the Dominican University community. Participants were randomly assigned to either the Therapeutic Listening® intervention or white noise control intervention. All participants completed a pretest to establish a baseline of bilateral coordination abilities. Participants then listened to 15-minutes of the intervention, followed by the posttest. The testing measures include subtests of the Bruininks- Oseretsky Test of Motor Proficiency (BOT-2), Sensorimotor Performance Analysis (SPA), Quick Neurological Screening Tool (QNST-3), and the Infinity Walk. Significant improvements in BOT-2 bilateral scores, and quality of movement were observed within the Therapeutic Listening® group between pretest to posttest after a single listening session, however, improvements were not seen in the white noise group. No significant changes were seen in QNST-3, SPA, and Infinity Walk scores. Results show promise for Therapeutic Listening®, and adds to the body of evidence supporting its use for improving motor skills in children.

Potential Role of Micro-Algae on Global Energy Supply
Sage Callaway-Keeley and Stephanie Huynh
The most effective ways to reduce CO2 emissions are to improve the energy efficiency of each economic sector and to reduce the cutting of tropical and temperate forests around the world. These options, however, may not fully reach their technical and economic potential due to various political and socioeconomic. The most practical of these is to increase CO2 sinks through photosynthesis in both standing tree biomass and in ocean primary producers. The use of marine algae as CO2 sinks is for large-scale CO2 mitigation: the use of phytoplankton through Fe fertilization and macro algal (kelp) farms, which can be used for energy production. The reduction of CO2-emissions that are damaging our climate is one of the major challenges of contemporary energy management. Nature itself offers us possibilities to produce energy CO2-neutral with the help of hydrogen producing micro-algae. Under certain conditions the light energy collected by photosynthesis is used to transfer electrons to hydrogen producing proteins called hydrogenases. A new type of hydrogenase that produces molecular hydrogen at relatively high rates was isolated (Happe and Naber, 1993) and characterized at the genomic level (Happe and Kaminski, 2002) for the first time in green algae. Processes were recently developed that allow long-term production of hydrogen by micro-algae (Melis et al., 2000). Under sulphur deprivation the green alga Chlamydomonas Reinhardtii adapts its metabolism from oxygen production and CO2-fixation towards hydrogen production. Therefore the biotechnological process is divided into the growth phase, the hydrogen production phase, and the resulting spent algae can be used for biomass production of fuel. Thus by control of growth conditions green algae can be used to produced hydrogen fuel, methane and a whole host of hydro carbons for fuel. Our planet is 75% ocean; it seems only natural to look to the ocean as a source of energy and a source to help lower our atmospheric CO2. The most appropriate regions for this kind of production would not only be the continental shelf regions but also in the open ocean where iron fertilization is being utilized to help with algal blooms. Algae and kelp may not be the holy grail of green energy sources, but they are a viable resource to help in our energy and environmental crisis.

Biofuels: A Hands-On Approach, Learning the Potential of Utilizing Non-Food Sources
Alexandra Ham, Gabrielle Pecora, Hoaithuong Bui, Timothy Camarella, Victor Pham, and Marc Ting
The global energy economy is huge and thoughts of replacing large amounts of petroleum based fuels by massive levels of fermentation of grains are not realistic. On an energy basis what global agriculture produces for food will almost cover the energy demands if all of it is redirected to the production of fuels—either as alcohols for gasoline or as fat derivatives for diesel fuel. This means that chemical processes need to be developed that allow inclusion of non-food based agricultural and urban wastes as well as forest debris into the energy economy. These represent opportunities to capture new sources of energy that would otherwise not be captured. This project is based on the idea that every little bit helps, and focuses on a hands-on approach to isolating chemicals from fallen vegetation with an emphasis on adding to the transportation fuel pool. Hydrolysis of cellulosic wastes from various sources easily collected on our campus has been explored seeking ways to break them down to fermentable sugars. These sugars are then fermented to form alcohols suitable for inclusion in gasoline. Extraction of vegetable oils has also been explored. Finally an attempt has been made to quantify the impact such a strategy might have on global energy supplies if practiced on a wide-scale basis.

Making Soap From Readily Available Agricultural and Household Wastes can Increase Cleanless in Rural Area
Eugenia Lucas and Thomas Ciaglo
In some areas of the world, soap is too expensive for many people to afford. For these people an alternative exists. They can make their own soap. In general, soap is made by the reaction of triglycerides and caustic soda. However, caustic soda, too, may be difficult to find or too expensive. The aim of this project is to develop a process for making soap from readily available agricultural and household waste materials, and other inexpensive chemicals. By using this process, rural people can get the benefits of readily available, inexpensive soap. Soap is made from animal fats or vegetable oils by saponification using strong base. The simple soaps can be isolated as cakes or bars, or it can be used as water solution. Many reaction conditions were studied to develop a recommended process that can be done using equipment and reaction conditions that can be performed in a kitchen or a fireplace. The soaps from this project were characterized primarily using infrared spectroscopy and several other analytical techniques as well as tests to show their effectiveness.
