The purpose of this study was to evaluate the presence of challenging behavior in those with DS by surveying caregivers of individuals with DS via Qualtrics. A link to our survey was sent out to national and local organizations that support the DS population with a request to disseminate the link. Given limited response, the survey was modified (shorted and reorganized) and a link to the revised survey was disseminated via Facebook to groups focused on DS. Although both surveys received limited responses, there are preliminary findings worth exploring further. Aggression, noncompliance, and tantrum behaviors were frequently reported behavior and, escape and attention were the most reported perceived functions of behavior. Challenging behavior is reported in DS by caregivers. Future research should be conducted to examine the prevalence and function of challenging behavior in DS to develop effective preventative approaches to challenging behavior while promoting skill acquisition.","PeriodicalId":46753,"journal":{"name":"Journal of Student Affairs Research and Practice","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85528468","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}

It is caused by mutations in the ABCD1 gene, which provides instructions for making a protein called ABCD1, which is involved in the metabolism of very long-chain fatty acids (VLCFAs). In ALD, the body cannot properly break down and clear VLCFAs, which can lead to the accumulation of these fatty acids in the brain and other tissues. This accumulation can cause inflammation and damage to cells and tissues, leading to various symptoms. Symptoms of ALD may vary depending on the type of ALD and the severity of the condition. Common symptoms include neurological problems, such as difficulty walking, speaking, behavioral changes, and problems with the adrenal gland, such as adrenal insufficiency which is a condition in which the adrenal glands do not produce enough hormones. ALD is a progressive disorder, meaning symptoms may worsen over time if left untreated. Treatment for ALD typically involves medications and supportive care to manage symptoms and prevent complications. Sometimes, a bone marrow transplant may be recommended to replace damaged cells and tissues. \u0000Genetic testing is available for ALD and can be used to diagnose the disorder and identify people at risk of developing it. Early diagnosis and treatment can help improve the chances of a full recovery and a good quality of life for people with ALD.","PeriodicalId":46753,"journal":{"name":"Journal of Student Affairs Research and Practice","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88092867","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 is currently no treatment for AD that halts the progression from cognitively normal (CN) and/or mild cognitive impairment (MCI) to AD. The ability to predict disease progression will allow for early treatment. While Machine Learning (ML) has been successful in diagnosing the cognitive state, further improvement is necessary for predicting progression. In this study, Random Forest and Bagging Decision Tree Recursive Feature Elimination (RFE) was utilized to ascertain the cognitive state and forecast progression. Clinical diagnoses, demographics, and post-processed PET and MRI scans used in this study were obtained from the Open Access Series of Imaging Studies (OASIS). The findings suggest that aging and lower levels of education are associated with higher risk. The study found that ML using post-processed MRI and PET scans, particularly RFE ML, is effective in diagnosing cognitive states with 90% accuracy. It can predict progression from CN to MCI or AD with 85% accuracy, which is significantly higher than the average reported in literature. Patients with progression from CN to AD were distinguished by elevated amyloid deposition, hippocampus and amygdala atrophy, left accumbens atrophy, thinning of the left hemisphere temporal, and enlarged inferior lateral ventricles. The study demonstrated that RFE ML is effective in diagnosing and predicting the progression of AD. Future studies will concentrate on identifying the specific regions of amyloid plaque that have the most significant impact on cognitive state and progression. \u0000 ","PeriodicalId":46753,"journal":{"name":"Journal of Student Affairs Research and Practice","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91041863","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}

Impacting the physical upper ocean characteristics, ENSO exerts significant influences on the marine ecosystem, such as oxygen and phytoplankton concentrations via strong quasiperiodic oscillation between El Niño (warm phase) and La Niña (cold phase) events. The present study uses observational reanalysis and satellite data to investigate seasonal variations of ENSO and their impacts on marine biogeochemical processes. The results show that the oxygen and chlorophyll anomalies in the upper ocean exhibit different seasonal responses to ENSO. While both the summer and winter season biological responses significantly lag ENSO, the concentration of oxygen and phytoplankton during summer (winter) has no (large) concurrent covariability with ENSO. Given a strong negative correlation between chlorophyll-based indices and El Niño events, increasing mean ocean temperatures and ocean extreme events may induce lower upper-ocean oxygen levels, leading to possible risks in the ecosystem over the tropical Pacific Ocean.","PeriodicalId":46753,"journal":{"name":"Journal of Student Affairs Research and Practice","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88389359","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}

In this paper, we examine the impact of traditional and social media on political polarization in society via simulations. These simulations examine what happens when a population with normally distributed unipolar political views is exposed to social/traditional media espousing very different types of political views. Our simulations reveal that the political polarization in a population is deeply affected by the political views espoused in the media. If the media is primarily unipolar in terms of political views, the population ultimately become politically unipolar as well. On the other hand, if the media is politically bipolar, the population ultimately becomes politically bipolar. Interestingly, the simulations reveal that social media echo chambers can undo the polarizing impact of partisan traditional media if the echo chambers strictly show content matching the current political views of the users. However, if social media echo chambers expose the users to extreme political views, a population that is initially unipolar in political views will ultimately look like two different populations with very different political centers.","PeriodicalId":46753,"journal":{"name":"Journal of Student Affairs Research and Practice","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88133369","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}

Another presiding issue is the output of cellulose left over from other plants that are used for biofuels, such as corn. However, the microalgae, Chlamydomonas Reinhardtii, a unicellular organism, is an ideal source of energy, as there is evidence that it contains the genes that are responsible for the encoding of Cellulases, which allow for the degradation of cellulose, such as endoglucanases. Chlamydomonas Reinhardtii typically lives in both soil and water environments, a photosynthetic organism that utilizes light as an energy source. The uncommon trait for microalgae to express cellulase allows for external sources of carbon to be utilized by the microorganism, which could affect the biological output of macromolecules common in biofuels such as lipids and carbohydrates. The study aims to compare not only the cellulase expression levels of Chlamydomonas Reinhardtii, but also see how the lipid output of the microalgae compares to other microorganisms used in the biofuel industry such as Chlorella Vulgaris, another phototrophic microalgae, which is used for direct fuel. Additionally, Trichoderma Reesei will also be compared, which is another microorganism that is used for biofuel production. However, the industry utilizes Trichoderma Reesei’s ability to produce cellulase, rather than just taking directly from the microorganism. The conclusions unfortunately did not show any cellulase expression, and biofuel output favored algae","PeriodicalId":46753,"journal":{"name":"Journal of Student Affairs Research and Practice","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86602946","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}
