Kennedy made it a mission for the National Aeronautics and Space Administration (NASA) to accomplish a lunar landing and return to Earth. The final lunar landing and the last time humans left Low Earth Orbit (LEO) was in December, 1972. However, 47 years have passed and the fascination with traveling into deep space remains alive and flourishing. A major problem with future human missions to Mars is the effects of microgravity and Mars’ 0.38g environment. Unfortunately, space medicine is limited and little is known about the effects of microgravity on the human body after one year in space. Is it possible for astronauts to survive long spaceflight missions to Mars? To help address this question, my research focuses on the effects of microgravity on astronauts in order to find solutions for long-duration space flights to Mars. Bone and muscle loss are factors that could lead to severe, unknown consequences on an astronaut’s health. My methods included doing an analytical interpretation of historical and contemporary research on long-distance spaceflight. In the future, longer missions are going to require more permanent solutions for humans to be an interplanetary species. The current solutions being used in the International Space Station (ISS) are only to treat individual symptoms separately. Only theoretical permanent solutions were found, such as artificial gravity; therefore, further research is needed. Centripetal acceleration has shown great promise to eliminate microgravity effects but more research is needed to understand the health consequences and the limitations of rotation that humans can sustain.","PeriodicalId":150197,"journal":{"name":"McNair Research Journal SJSU","volume":"592 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116309859","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}

{"title":"English Language Minority Students and Education Policy: A Focus on the Latinx Population","authors":"María de los Ángeles De Santos Quezada","doi":"10.31979/mrj.2019.1510","DOIUrl":"https://doi.org/10.31979/mrj.2019.1510","url":null,"abstract":"Our federal government allows states to pass and ratify new laws every year. Over the last thirty years, America has experienced a polarized fight over the expansion or reduction of government involvement. In terms of education policy, local districts and governments can play an essential role in the implementation, evaluation, and development of equitable educational opportunities. This paper examines federal and state level policies in the context of English Language Learners’ (EL) educational opportunities. In particular, I focus on Mt. Diablo High School, which is located in the Mount Diablo District. According to the California State Department of Education, the percentage of English Language Learners at this school is 33.5%. Out of this percentage, a majority of English Language Learner students at Mt. Diablo High School are Latinx (84.98%). These statistics help to demonstrate that state and district level policies lack inclusivity, student awareness on academic resources, accessibility to career center programs, and a lack of parent and teacher participation. Due to these shortcomings, these policies primarily feed into the undereducation and retention of EL students. By analyzing existing Student Site Council meetings and state-level data sets, I argue that there is a higher need for accountability and support relative to the number of EL students attending Mt. Diablo High School. 2 McNair Research Journal SJSU, Vol. 15 [2019], Art. 10 https://scholarworks.sjsu.edu/mcnair/vol15/iss1/10 106 Introduction During 2013-2014, unaccompanied child migration from Central America to the U.S. reached its peak. According to the article, “As immigration resurges, U.S. public schools help children find their footing” published by the Washington Post in 2016, the influx of immigrant children to our public schools has been a challenge—not only for these newcomers, but also for the teachers, staff, parents, and policymakers. However, as many are aware, migration is not a new topic in this country; in 1965, when The Immigration and Naturalization Act abolished some of the xenophobic quotas in previous times, the demographics of the U.S. significantly changed. Today, one in four children in the U.S. are the children of immigrants (Gandara, 2018). The United States Department of Education faces the great responsibility of educating every child in this nation. One of the programs that attempts to accommodate newcomers into public schools is the English Learner Development program. According to Laura Hill, a researcher at the Institute of Public Policy in California, the number of EL students in the California education system is around 1.3 million. Any student who enrolls in K-12 education in California and speaks a language other than English is automatically considered and classified as an English Learner student—a status that is meant to be temporary. (Hill, 2018) The current population of EL students in California public schools is large and diverse.

This suggests it is important to discover what individual differences may cause a user to be more or less vulnerable to cyber security threats. Cyber security knowledge has been shown to lead to increased learning and proactive cyber security behavior (CSB). Self-efficacy has been shown to be a strong predictor of a user’s intended behavior. Traits such as neuroticism have been shown to negatively influence cyber security knowledge and self-efficacy, which may hinder CSB. In discovering what individual traits may predict CSB, users and designers may be able to implement solutions to improve CSB. In this study, 183 undergraduate students at San José State University completed an online survey. Students completed surveys of self-efficacy in information security, and cyber security behavioral intention, as well as a personality inventory and a semantic cyber security knowledge quiz. Correlational analyses were conducted to test hypotheses related to individual traits expected to predict CSB. Results included a negative relationship between neuroticism and self-efficacy and a positive relationship between self-efficacy and CSB. Overall, the results support the conclusion that individual differences can predict self-efficacy and intention to engage in CSB. Future research is needed to investigate whether CSB is influenced by traits such as neuroticism, if CSB can be improved through video games, and which are the causal directions of these effects.","PeriodicalId":150197,"journal":{"name":"McNair Research Journal SJSU","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131918114","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}

This current review of literature seeks to make a comparison of Imposter syndrome between two marginalized communities – Asian Americans and African Americans. Imposter syndrome, also referred to as the imposter phenomenon, refers to an individual who doubts their own skills, abilities, successes, and overall capabilities in their life (Parkman, 2016). Asian American students are stereotyped as the model minority and are believed to be intelligent, hardworking, high achieving, and academic and seen to be free from any emotional or adaptive problems. Although these stereotypes are perceived to be positive, they also place a great deal of pressure on Asian American students to excel in school and this can produce increased anxiety and distress. Among African-Americans, shame-proneness manifests differently. It is directly related to a fear of intimacy and self-deprecation (Austin, 2009). Researchers looking at the relationship between Imposter syndrome and mental health among student populations have found it to be a predictor of mental health, it has been found to be positively correlated with anxiety, depression, psychological distress, and minority student status stress (Parkman, 2016). This review will seek to answer which of the two aforesaid stated student populations of first-generation students, Asian American and African American experience a greater detriment in mental health and if there are any specific patterns of mental symptoms of psychological distress that are found among each of these student populations.","PeriodicalId":150197,"journal":{"name":"McNair Research Journal SJSU","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116065450","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}

The stretch reflex is a muscle contraction in response to muscle stretch. We hypothesize that the acute inflammation caused by an injection of lipopolysaccharide (LPS) will cause an increase in spinal cord excitability. To test this hypothesis, we measured Hoffman’s (H) reflex, the electric analog of the stretch reflex in adult mice receiving an injection of LPS (.5mg/kg) or saline (200μl). Adult male and female mice (C57Bl/6) were anesthetized; then, the sciatic nerve was exposed and stimulated at current strengths from H-wave threshold (T) to 8T (20 x 0.1 ms pulses at 0.1 Hz). Recording electrodes were placed in the foot. We measured the maximum M wave amplitude (Mmax), maximum H wave amplitude (Hmax) and latencies of both waves. We compared the ratio of the maximal H wave over the maximal M wave (Hmax/Mmax), which reports the percentage of motor neurons activated by electrical stimulation of Group Ia muscle sensory neurons. Increased spinal cord excitability would be reflected in a larger Hmax/Mmax. We found that LPS-induced inflammation does not alter the Hmax/Mmax. While we found no evidence of changes in spinal cord excitability, inflammation could be altering Group Ia muscle spindle afferent responses to stretch. Future studies will test whether stretch reflex strength is altered by inflammation. Introduction Hoffman’s reflex (H-reflex) is an electrically induced reflex. The H reflex estimates of alpha motor excitability, which can be used to evaluate the response of the nervous system to different neurological conditions. The M wave is a contraction caused by direct stimulation of motor neuron axons and the H wave is derived from the reflex activation of the motor neurons by electrical stimulation of Group Ia afferents (Palmeri, Ingersoll, & Hoffman, 2004). 2 McNair Research Journal SJSU, Vol. 14 [2018], Art. 11 https://scholarworks.sjsu.edu/mcnair/vol14/iss1/11 DOI: 10.31979/mrj.2018.1411 142 Lipopolysaccharide (LPS) is a bacterial endotoxin found on the capsule of gram-negative bacteria (Gao et al., 2002). LPS is also known to cause an immune response in animals. Inflammation is synonymous with many neurodegenerative diseases (Qin et al,. 2004). When LPS is injected in an animal, cytokines, specifically TNFα, is released into the body (Qin et al., 2004). These cytokines cause a low level of chronic inflammation, much like a person gets when they catch the flu. Peripheral inflammation alters the excitability of dorsal horn interneurons and increases flexor reflex strength (Dubner & Ruda, 1992); however, its effect on the spinal stretch reflex is not well understood. My hypothesis is that LPS induced inflammation will increase spinal cord excitability; I expect to see an increase in HMax/MMax and earlier latencies in drug groups as c","PeriodicalId":150197,"journal":{"name":"McNair Research Journal SJSU","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116162043","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}

They have advanced in social class, education and political representation. On the other hand, Salvadorans have only just recently begun migrating and settling in predominantly Mexican/Mexican American communities. Competition over resources and the preservation of Mexican/Mexican American culture has caused continuing conflicts among Salvadorans and Mexicans/Mexican Americans. Additionally, inter-ethnic and in-group conflicts are also affected by generational differences (1, 2, 3 generation, etc.). Due to acculturation, Latinos/as struggle to retain their cultural heritage and parents often lose the ability to influence their children’s ethnic identity (customs, language, social norms). My research aims to contribute to the development and maintenance of ethnic identity and understanding of interethnic conflicts they face amongst Mexicans in California. I will briefly explore the migration patterns of Salvadorans and Mexican/Mexican Americans from past research focusing on ethnic identity development and how it may be connected to generational differences, experiences based on acculturation and discrimination, and family ethnic socialization, how ethnic identity is associated with positive self-esteem, and how marginalization can create group conflict among Latinos/as; specifically with Salvadorans and Mexican/Mexican Americans. The purpose of this research is to educate and bring to light the different experiences of Latinos/as and the struggles to retain ethnic identity and positive self-esteem. Although most research focuses on the Mexican experience, my research will attempt to incorporate the Salvadoran experience— one that reflects Salvadorans’ being a double minority: within wider American society and within their Latino/a ethnic group. In doing so, I wish to bring attention to this inter-ethnic conflict that has not been explored enough. 2 McNair Research Journal SJSU, Vol. 14 [2018], Art. 4 http://scholarworks.sjsu.edu/mcnair/vol14/iss1/4 25 Historical Background In order to better understand the Salvadoran/Mexican conflict, learning about the Latino/a diaspora is important. It is also worth noting that the Salvadoran/Mexican conflict is not the only one that occurs amongst Latinos/as, but it is the one I will focus on. Latinos/as from different nationalities have migrated to the U.S for various reasons throughout history. The three largest groups in the U.S are Mexican Americans (or Chicanos), Puerto Ricans and Cubans (Totti 1987). Geographically these groups migrated to different parts of the U.S.; according to Zong and Betalova (2014), Mexican Americans mostly settled in California, Texas and Illinois. Mexican migration to the U.S was caused by the demand for jobs and political instability in their countries. The first wave of migration occurred prior to WWII, and most of the migrants at the time were agricultural workers wh","PeriodicalId":150197,"journal":{"name":"McNair Research Journal SJSU","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114232051","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}

Peer Leaders receive training to provide outreach to educate the campus community about the needs and perspectives of veterans (Klaw, Li, Avalos, & Diaz, 2016). As part of a larger project exploring the effects of VET Connect, exploratory findings in qualitative research indicate that through their participation in VET Connect student veterans gained a sense that civilians do indeed care (12, 92%) about veterans. Over half of the participants (8, 61%) reported changing ideas about themselves as veterans, seeing themselves at first as “not needing anybody” and then discovering that relationships were important to their sense of self. In their services as peer educators, these students discovered that they were not significantly different from other SJSU students as diverse and varied individuals. This study was conducted in collaboration with Jemerson Diaz. We worked on independent research questions and observations using data derived from the same larger study simultaneously under the supervision of Dr. Klaw. Introduction Currently, over one million veterans are receiving VA education benefits, known as the GI Bill, to pursue college diplomas, advanced degrees, or vocational training (Veteran Affairs, 2016). As the number of student veterans increases, colleges need to become more equipped to provide support services for this diverse population. One of the most predominate challenges veterans face according to Rumann & Hamrick (2010) is transitioning into a college environment. The reason many struggle to integrate is due to social barriers, such as not relating to civilian college students. In a college environment, it is probable that student veterans face challenges in having to interact with civilian students (Brookover, 1945). The American Council on Education reports (Radford, 2 McNair Research Journal SJSU, Vol. 13 [2017], Art. 5 https://scholarworks.sjsu.edu/mcnair/vol13/iss1/5 DOI: 10.31979/mrj.2017.1305 21 2009) that 85% of college student veterans are at least 24 years old, and over 60% have a dependent spouse or child. Student veterans and traditional college students appear to have different lifestyles, which may be a part of the reason for differences in interests, social interactions, and interest in engaging with each other (Rumann & Hamrick, 2010) Difference in lifestyles may also lead to civilians and student veterans holding inaccurate ideas about each other.

This soaring obesity rate contributes to poor health outcomes and significantly inflates the risks for many chronic diseases, including cardiovascular diseases, diabetes, and certain forms of cancer. The literature provides evidence for the success of health programs aimed at promoting healthy behavior and lifestyles in African-American faithbased organizations, as the influential role of churches in African-American communities is well documented. However, few studies have investigated the criteria essential for improved efficiency of health interventions addressing the problem of obesity in the church-based environment. This paper examines the sociocultural and environmental factors associated with enhanced efficiency of health-promotion programs to reduce obesity in African-American faith-based communities. The databases PubMed, CINAHL Complete, Cochrane Library, and PsycINFO were searched, and ten relevant articles published during the last five years were selected. The findings corroborate prior research about the instrumental role of churches to promote a healthy lifestyle and reduce obesity among AfricanAmericans. We identify that a partnership between health educators and the community is crucial to achieve a high success rate in church settings. These results indicate that better success is achieved when the church leadership and churchgoers' input are integrated into the program’s design. Furthermore, health educators need to have a good grasp of the participants’ cultural perceptions, understanding, and expectations of obesity. We recommend that future researchers examine the cultural and spiritual strengths of these faith-based communities and the best strategies to use in order to achieve long-term weight loss.","PeriodicalId":150197,"journal":{"name":"McNair Research Journal SJSU","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122508451","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}
