While both hardware and software have continued to evolve rapidly over time, ISAs have undergone minimal change. Since its release in 2010, RISC-V has begun to erode the industry aversion to ISA innovation. Established on the principals of the Reduced Instruction Set Computer (RISC), and as an open source ISA, RISC-V offers many benefits over popular ISAs like Intel’s x86 and Arm Holding’s Advanced RISC Machine (ARM). In this literature review I evaluate the literature discussing: What makes changing Instruction Set Architectures difficultWhy might the industry choose to implement RISC-V When researching this topic I visited the IEEE (Institute of Electrical and Electronics Engineers), INSPEC (Engineering Village), and ACM (Association for Computing Machinery) Digital Library databases. I used the search terms, “RISC-V”, “Instruction Set Architecture”, “RISC-V” AND “x86”, and “RISC-V” AND “Instruction Set Architecture”. This literature review evaluates 10 papers on implementation of RISC-V.

Foster youth are children, teens, and young adults who are placed in varying institutions due to lack of parental neglect, mental, or physical abuse. The most prevalent cause of their displacement into government provided institutions, is neglect. Foster youth have encountered differing forms of adversities that affect their daily life. The abuse these children and youth encounter is often times traumatic. Some of the trauma can be a combination of: mental abuse, physical abuse, sexual abuse, and much more. As such, their lives are altered and therefore affect their long-term functioning domains. They often have difficulty in demonstrating emotional connections or expression of them. The research that will be discussed is are the factors that influence a positive outcome on the prevalence of resiliency among foster youth. Some of the factors discussed will be external and internal factors that are included but not limited to: behavioral, social, and cognitive developments as well as, social relationships and external institutional support.

{"title":"Reusable Rockets and the Environment","authors":"Andres Israel Torres","doi":"10.5070/M4122048807","DOIUrl":"https://doi.org/10.5070/M4122048807","url":null,"abstract":"Author(s): Torres, Andres Israel | Abstract: Many studies have been conducted on the environmental impact of automotive vehicles, but less research has been done on the effects of orbital launch vehicles. This literature review addresses the question, what are the environmental effects of reusable rockets? The environmental effects that are considered include pollution to the atmosphere, soil, and Low Earth Orbit in the form of space debris. Also, reusable orbital launch vehicles are specifically considered because their reduced costs could increase launch frequency. The impact of rockets in general has been difficult to quantify because rockets are not launched very often, and they mostly operate in space. Research has shown that launch prices are decreasing while their total environmental effects is unknown (Jones, 2018). However, research agrees that space debris is a considerable threat to future space activity that will only get worse, but there is no consensus as to when the problem will be too great (Noble, Almanee, Shakir, a Sungmin Park, Apr 2016; Sliz-Balogh, Horvath, Szabo, a Horvath, 2020).When considering reusable orbital launch vehicles, it is specified that these types of vehicles are rockets that can insert payloads with considerable mass into orbit around Earth or even away from Earth into deep space. There are many rockets currently operational with this capability, but only two are reusable at the time: The Falcon 9 and Falcon Heavy. Unlike their conventional counterparts, these rockets do not eject and discard their first stage. Instead, they recover and reuse it. However, conventional and reusable rockets are similar because they discard their second stage after their payloads have been deployed.The research conducted in this literature review was taken from databases accessed through the UC Merced library website. They include Engineering Village, Web of Science, Sax’s Dangerous Properties of Industrial Materials, etc. Ten sources were referenced which were found using several key search terms including reusable, rocket*, pollution, propellant, space, debris, exploration, etc. Some of the terms were searched in combinations using key phrases like reusable rocket, space debris, rockets AND pollution, etc. Due to the limited research on the environmental effects of rockets on the ocean, it was not mentioned. For example, there were ninety-seven and fifty-eight results under the phrase rocket AND ocean, in Engineering Village and IEEE Xplore databases respectively. None of the papers had anything to do with environmental effects.","PeriodicalId":131320,"journal":{"name":"UC Merced Undergraduate Research Journal","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122975741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are many studies showing what can be done to decrease resistance of many microbes, but there is not one complete method. This review indicates the effective methods that can be used to prevent resistance from spreading in hospitals.Methods: The review was set to focus on antimicrobial resistance, misuse, and overuse of antimicrobials, what doctors are doing that influences resistance and stewardship programs. Articles published from 2008- 2018 were found using Web of Science, ScienceDirect, and PLOS.Results: Out of the 15 articles found, 7 articles met the ideal selection criteria and were included in the review. All articles demonstrated the importance of antimicrobial resistance and provided ways in which resistance can be decreased. All studies reported the use of stewardship programs were necessary, but only three articles demonstrated its effectiveness.Conclusion: This review demonstrates a high need for antimicrobial stewardship programs to decrease the evolution of antimicrobial resistance. However, there is a problem with individual medical providers not complying to such programs due to the restrictions they say it creates. The results state otherwise and in fact demonstrate how a medical provider’s behavior must change to provide significance on the implementation of successful stewardship programs.","PeriodicalId":131320,"journal":{"name":"UC Merced Undergraduate Research Journal","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132317294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, training a classifier algorithm to accomplish this form of behavioral observation is a rather difficult task. In this exploratory review, we will be replicating object recognition and deep learning in a convolutional neural network to ultimately train a model to distinguish the universal human emotions from the FER2013 facial expression dataset (Kaggle, 2013).","PeriodicalId":131320,"journal":{"name":"UC Merced Undergraduate Research Journal","volume":"351 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131435848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To classify what is considered “prestigious” and non- “prestigious”, I used rankings from the U.S News Best Colleges Rankings to classify the University of California campuses onto two separate tiers based on these rankings. I implement a survey on Amazon Mechanical Turk, in which subjects are asked whether they would prefer to hire a job candidate with a higher GPA from a lower tier university versus a job candidate with a lower GPA from a higher tier university. Using this survey data, I find that subjects have a strong preference for candidates with higher GPA. This preference still holds when including respondents that have hiring experience. The implications are that individuals will re-evaluate their preferences when applying to a university.","PeriodicalId":131320,"journal":{"name":"UC Merced Undergraduate Research Journal","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131438419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
