A Dynamic Sir Model For The Spread Of Novel Coronavirus Disease 2019 (Covid-19) In Malaysia, Nur Aziean Mohd Idris, Siti Khadijah Mohtar, Zaileha Md Ali, Khadijah Abdul Hamid

Malaysian Journal of Computing (MJoC)

The emergence of the first coronavirus disease 2019 (COVID-19) case in Malaysia has increased the number of infected cases. Hence, this study proposes a Susceptible-Infected-Recovery (SIR) epidemiological model of the COVID-19 epidemic to portray the outbreak's situation. The SIR model is numerically solved using the Fourth-order Runge-Kutta (RK4) method in Matlab®. The Euler method verifies that the graphical results of the SIR model are reliable and valid. In addition, this study analyses the stability of disease-free and endemic equilibriums of the SIR model by the Jacobian matrix. The results show the outbreak for phase 1 occurs in the first 100 …

Chemical Interactions And Cytotoxicity Of Terpene And Diluent Vaping Ingredients, Yanira Baldovinos, Alexandra Archer, James C. Salamanca, Robert M. Strongin, Christie Sayes

Chemistry Faculty Publications and Presentations

Vaping devices have risen in popularity since their inception in 2007. The practice involves using a variety of commercially available devices. Internal heating systems in devices aerosolize e-liquid formulations of complex mixtures including an active ingredient (e.g., THC, CBD, and nicotine), diluents (or cutting agents), solvents, and flavoring agents (e.g., terpenes and aldehydes). The vaping toxicology literature consists of cytotoxicity studies of individual chemicals and commercial formulas. Because of the variation of e-liquid composition, there is a limited understanding of the toxicity of ingredient combinations. This study analyzed the cytotoxic effects after exposure to individual and binary mixtures of a …

Extreme Tail Ratios And Overrepresentation Among Subpopulations With Normal Distributions, Theodore P. Hill, Ronald F. Fox

Research Scholars in Residence

Given several different populations, the relative proportions of each in the high (or low) end of the distribution of a given characteristic are often more important than the overall average values or standard deviations. In the case of two different normally-distributed random variables, as is shown here, one of the (right) tail ratios will not only eventually be greater than 1 from some point on, but will even become infinitely large. More generally, in every finite mixture of different normal distributions, there will always be exactly one of those distributions that is not only overrepresented in the right tail of …

The Battle Of The First-Year Medical Student, Kimberly A. Kluglein

be Still

I wrote this poem to reflect the way I believe a lot of first-year medical students feel. The internal conflict that arises within ourselves. I personally have doubted whether I am good enough to be where I am today and I know I am not alone in that feeling. A million people could tell you that you are good enough, but it doesn't matter unless you believe that for yourself. I think it is important to take time to reflect and remember even when it is difficult, that you can do it, and that you are worthy.

Baghdad Science Journal

Polycystic ovary syndrome (PCOS) is the main cause of female infertility. The role of insulin resistance in the development of polycystic ovary is actively discussed here. The study included patients with PCOS without insulin resistance (n = 48) and with insulin resistance (n = 39). The comparison groups were patients with no history of PCOS: a control group without insulin resistance (n = 46) and a group of patients with insulin resistance (n = 45). The following parameters were determined in patients: FSH, LH, TSH, T3f, T4f, PRL, E2, 17-OHd, Pr, AMH, Test total, Testf, DHEAS, DHEASs, SHBG, ACTH, cortisol, …

The Role Of Museums In Educational Pedagogy And Community Engagement, Katherine E. Weber

College of Education Theses and Dissertations

Museums provide exceptional opportunity for experiential and social/emotional learning that often cannot be simulated elsewhere. Schools and communities, however, are not taking full advantage of what these spaces have to offer. Learning science has indicated the need for more progressive education initiatives, making stronger partnerships between museums, schools, and communities imperative. Data was collected through surveys and interviews with museum education departments and K-12 teachers in the Chicagoland area to discuss available programs, usage, outcomes, and feedback for improvement. Analysis of data reiterated the positive role museums play in creating well-rounded, critically-thinking, emotionally intelligent individuals, who are civically engaged and …

Rise And Shine: The Use Of Polychromatic Short-Wavelength-Enriched Light To Mitigate Sleep Inertia At Night Following Awakening From Slow-Wave Sleep, Cassie J. Hilditch, Lily R. Wong, Nicholas G. Bathurst, Nathan H. Feick, Sean Pradhan, Amanda Santamaria, Nita L. Shattuck, Erin E. Flynn-Evans

Faculty Research, Scholarly, and Creative Activity

Sleep inertia is the brief period of performance impairment and reduced alertness experienced after waking, especially from slow-wave sleep. We assessed the efficacy of polychromatic short-wavelength-enriched light to improve vigilant attention, alertness and mood immediately after waking from slow-wave sleep at night. Twelve participants (six female, 23.3 ± 4.2 years) maintained an actigraphy-confirmed sleep schedule of 8.5 hr for 5 nights, and 5 hr for 1 night prior to an overnight laboratory visit. In the laboratory, participants were awakened from slow-wave sleep, and immediately exposed to either dim, red ambient light (control) or polychromatic short-wavelength-enriched light (light) for 1 hr …

Burnout In The Field Of Forensic Psychology And Intervention Techniques, Taylor Gary

Dissertations

Forensic psychologists are at a heightened risk for encountering vicarious trauma, compassion fatigue, and burnout, all of which influence quality and continuity of care (Sansbury et al., 2015). The current literature review aims to discuss how burnout relates specifically to the field of forensic psychology. For the purposes of this discussion, clinical psychologists who perform forensic duties, as well as board certified forensic psychologists are considered. Research questions that are addressed in this discussion include what the existing research states regarding vicarious trauma in forensic settings, likely gender differences in burnout and vicarious trauma, and documented interventions that appear most …

Medical Martial Law: Towards A More Effective Pandemic Policy, John W. Bagby, Robert J. Aalberts, Chad G. Marzen

Southern Illinois University Law Journal

This article synthesizes the political-economic geography regime with existing political subdivision modeling to predict the legitimacy of various authorities that might order Medical Martial Law. Such “districting” authority, as limited by the Constitutional right to travel, reveals a range of authorities to declare and enforce remediation of emergencies under various legal frameworks within defined geographic areas. The primary interdisciplinary approach used here is public policy, political economy and economic geography. We demonstrate how the latter contributes greatly. First, the science of spatial understanding is offered by physical geographers for the physical barriers that shape political borders and may define contagion …

Termination Of Parental Rights And An Assessment Of Rights To Subsequent Children In The State Of Illinois, Kayla C. Ranta

Southern Illinois University Law Journal

In the United States, it is considered a fundamental constitutional liberty for a parent to be able to control the upbringing of their children. Under this construction, unless a parent’s care reaches the extent of abuse or neglect, affecting a child’s health, welfare, or safety, they should be free to parent their child(ren). Yet, despite this construction, a finding of parental unfitness as to one child will allow an Illinois family court to terminate the parental rights of that individual toward all subsequent children. This process does not currently have any exceptions for parents whose circumstances have changed or who …

The Effect Of Isolation On The Mental Health Of Older Adults, Christina Yates

Senior Honors Theses

As individuals age and lose mobility and cognitive functioning, many require full-time care which their loved ones are unable to provide. This often results in placement into long-term care facilities, and these facilities are notorious for being understaffed. Physical health becomes the only priority, depriving the client of having their mental and emotional needs fulfilled. Family and friends may decrease visitation due to distance or convenience. In 2020, the Covid-19 pandemic closed the doors of many facilities to nearly all visitors. Thus, the only individuals the residents of these facilities experienced interaction with were overworked staff members looking intimidating in …

The Short-Form Of The Coparenting Across Family Structures Scale (Copafs-27): A Confirmatory Factor Analysis, Michael A. Saini, Marsha Kline Pruett, Jonathan Alschech

School for Social Work: Faculty Publications

To further refine the measurement of coparenting across family dynamics, this article presents data from 2 separately collected samples, the first consisting of 252 parents and the second consisting of 329 parents, analyzed as a pilot study of the Short-Form of the Coparenting Across Family Structures Scale (CoPAFS 27-Items). The purpose of the revised shortened tool is to further the design of an efficient and psychometrically strong tool to aid research and clinical practice with coparents. Our intent was to differentiate coparenting in intact, separated/divorced, and families where the parents were never romantically involved, between mothers and fathers, and between …

Intact Polar Brgdgts In Arctic Lake Catchments: Implications For Lipid Sources And Paleoclimate Applications, Jonathan H. Raberg, Edgart Flores, Sarah E. Crump, Greg De Wet, Nadia Dildar, Gifford H. Miller, Áslaug Geirsdóttir, Julio Sepúlveda

Geosciences: Faculty Publications

Paleotemperature histories derived from lake sediment archives provide valuable context for modern and future climate changes. Branched glycerol dialkyl glycerol tetraether (brGDGT) lipids are a valuable tool in such pursuits due to their empirical correlation with temperature and near ubiquity in nature. However, the relative contributions of terrestrial and lacustrine sources of brGDGTs to lake sediments is site-dependent and difficult to constrain. Here, we explored the potential for intact brGDGTs—the complete lipids with polar head groups (HGs) still attached—to provide insight into the sources of brGDGTs on the landscape and their contributions to the sedimentary record in a set of …

Open Access Publishing Support Funded Articles

Developing effective programs that aim to generate student interest in the pursuit of a career in healthcare is vital to avoid shortages among the workforce. As the American population ages, the country will continue to experience a higher demand for healthcare-trained individuals and services. Exposing racially diverse students to career options and the educational requirements early can serve as a pipeline for increasing interest in obtaining careers in healthcare professions overall. Program formatting resembles “summer camps” as it provides students with educational opportunities outside of the typical school curriculum. These summer camp designed “programs” have been an effective method of …

The Effectiveness Of Movement Control Order (Mco) Phases Implementation In Malaysia, Hezlin Aryani Abd Rahman, Muhammad Akram Rahman, ‘Ain Najihah Rozaimi, Irfan Bihar Zulnahar

Malaysian Journal of Computing (MJoC)

The COVID-19 cases have taken its strike since December 2019 in Wuhan, China and then has spread to other countries. Malaysia was not excluded from this pandemic, in which the first case of COVID-19 was discovered on 25th January 2020. The disease has caused a pandemic outbreak ever since, driving many countries to close international gateways and implement lockdowns and many studies have been trying to model and forecast the rising number of Covid-19 cases worldwide. This study aimed to prove the effectiveness of Movement Control Order (MCO) phases implemented in Malaysia. From 8 MCO phases implemented in Malaysia, 5 …

A Planetary Imagination: Responses To Chakrabarty’S Socio-Natural Historiography, Editorial Introduction, Jeremy Bendik-Keymer

Faculty Scholarship

Dipesh Chakrabarty’s 2009 essay in Critical Inquiry, “The Climate of History: Four Theses” sent tremors through the environmentally aware humanities in the 2010s. Last year, he published the book that brought that essay forward into the present, The Climate of History in a Planetary Age. It’s no overstatement to think of this book as having clanged the bell for a new normal in the humanities and social sciences when it comes to telling the story of ourselves, that is, when it comes to human history. Responsible history should today be geological even when recounting the human record. Chakrabarty raised a …

Oosterhoff, Julie Vignau, Sandra Verploegen, Peter Boross, Frank J. Beurskens, Diane S. Lidke, Janine Schuurman, Rob N. De Jong

Pathology Research and Scholarship

The use of therapeutic monoclonal antibodies is constrained because single antigen targets often do not provide sufficient selectivity to distinguish diseased from healthy tissues. We present HexElect, an approach to enhance the functional selectivity of therapeutic antibodies by making their activity dependent on clustering after binding to two different antigens expressed on the same target cell. lmmunoglobulin G (lgG)-mediated clustering of membrane receptors naturally occurs on cell surfaces to trigger complement- or cell-mediated effector functions or to initiate intracellular signaling. We engineer the Fc domains of two different lgG antibodies to suppress their individual homo-oligomerization while promoting their pairwise hetero-oligomerization …

Stable Coexistence Or Competitive Exclusion? Fern Endophytes Demonstrate Rapid Turnover Favoring A Dominant Fungus, Brett Steven Younginger, Nathan U. Stewart, Mehmet Ali Balkan, Daniel J. Ballhorn

Biology Faculty Publications and Presentations

Fungal endophytes are critical members of the plant microbiome, but their community dynamics throughout an entire growing season are underexplored. Additionally, most fungal endophyte research has centred on seed-reproducing hosts, while spore-reproducing plants also host endophytes and may be colonized by unique community members. In order to examine annual fungal endophyte community dynamics in a spore-reproducing host, we explored endophytes in a single population of ferns, Polystichum munitum, in the Pacific Northwest. Through metabarcoding, we characterized the community assembly and temporal turnover of foliar endophytes throughout a growing season. From these results, we selected endophytes with outsized representations in …

Natural Resource Management Faculty Publications

The U.N. Decade on Ecosystem Restoration aims to accelerate actions to prevent, halt, and reverse the degradation of ecosystems, and re-establish ecosystem functioning and species diversity. The practice of ecological restoration has made great progress in recent decades, as has recognition of the importance of species diversity to maintaining the long-term stability and functioning of restored ecosystems. Restorations may also focus on specific species to fulfill needed functions, such as supporting dependent wildlife or mitigating extinction risk. Yet even in the most carefully planned and managed restoration, target species may fail to germinate, establish, or persist. To support the successful …

Industrial Energy Development Decouples Ungulate Migration From The Green Wave, Ellen O. Aikens, Teal B. Wyckoff, Hall Sawyer, Matthew J. Kauffman

Natural Resource Management Faculty Publications

The ability to freely move across the landscape to track the emergence of nutritious spring green-up (termed ‘green-wave surfing’) is key to the foraging strategy of migratory ungulates. Across the vast landscapes traversed by many migratory herds, habitats are being altered by development with unknown consequences for surfing. Using a unique long-term tracking dataset, we found that when energy development occurs within mule deer (Odocoileus hemionus) migration corridors, migrating animals become decoupled from the green wave. During the early phases of a coalbed natural gas development, deer synchronized their movements with peak green-up. But faced with increasing disturbance …
