Corporate actions are commonly undertaken by companies to gain profits. An acquisition is one example of a corporate action that generates positive sentiment in the market, thereby attracting the attention of many companies. However, as a consequence of an acquisition, each company involved is required to make a mandatory tender offer for the remaining shares not acquired during the acquisition process. This mandatory tender offer is regulated by the Financial Services Authority Regulation No. 9/POJK.04/2018 (Regulation on the Takeover of Public Companies), which allows for certain exceptions in its implementation. The issue arises when the exception to the mandatory tender …

Auditory Vigilance Decrement In Drivers Of A Partially Automated Vehicle: A Pilot Study Using A High-Fidelity Driving Simulator, Luca Brooks, Jeffrey Glassman, Yusuke Yamani Mar 2024

Auditory Vigilance Decrement In Drivers Of A Partially Automated Vehicle: A Pilot Study Using A High-Fidelity Driving Simulator, Luca Brooks, Jeffrey Glassman, Yusuke Yamani

Undergraduate Research Symposium

Vigilance decrement is the decline in the ability to monitor and detect behaviorally important signals over time, a phenomenon that can arise even after 30 minutes of watch (Mackworth, 1948). Recently, McCarley & Yamani (2021) found bias shifts, sensitivity losses, and attentional lapses contribute to vigilance decrement, but when each effect is isolated, there was little evidence that sensitivity loss affected vigilance decrement. With the introduction of partially autonomous vehicles, vigilance decrement may be problematic for drivers who must monitor the autonomous system for failures and takeover requests. Thus, this pilot study aims to extend McCarley and Yamani (2021) and …

Parametric Design As A Tool To Reduce Solar Penetration By Outdoor Shades In Hot Arid Climate, Rana O. Aboulfaraj, Iman O. Gawad, Mostafa Khalifa

Architecture and Planning Journal (APJ)

Conventional design methods and current tools infrequently link performance with the geometry of the design. These methods rarely enable backtracking through the design process and can't achieve full performance criteria. In this context, using both procedural geometry and information from numerical assessments and performance simulations should be discussed to support the search for effective solutions. Architects have gained control over the process of design by utilizing parametric methods to generate a sustainable design that interacts with sustainable, climatic, and environmental restrictions, particularly in hot arid zones where outdoor life is overlooked. This paper will discuss the performance-oriented design and a …

Centuripe Ceramic Workshops And Their Distinct Funerary Vases, Avery Keys Mar 2024

Centuripe Ceramic Workshops And Their Distinct Funerary Vases, Avery Keys

Undergraduate Research Symposium

Ancient pottery from Centuripe, Sicily made during the Hellenistic period is an outlier when compared to most other red-figure, black slipped ceramics from Magna Graecia. Most Southern Italian and Sicilian vases have a distinct ornate style to them that was not a long lasting design choice in other Greek ceramic workshops. Funerary vases excavated in Centuripe's tombs provide a large collection of elaborate, decorative pottery that is not replicated anywhere else. Centuripean pottery was tempera painted with bright polychromatic colors. This unique quality of the ceramic ware has led scholars to focus on the color palette, the painted subject matters, …

Global Strategies For Addressing Communication Disorders In Justice-Involved Youth, Sophia Martinez, Anne Marie Perrotti, Brooke Baker, Allison Chappell

Undergraduate Research Symposium

Throughout all stages of processing, most juveniles who encounter the justice system demonstrate cognitive-communicative difficulties (CCDs). Empirical evidence reveals that 19-22% of female and 28-38% of male youth offenders, culminating in approximately 50-60% of youth offenders, demonstrate language disorders that require intervention, but most have never received services (Snow et al., 2014; Winstanley et al., 2021). Speech-language pathologists (SLPs) are communication experts certified to assess and treat CCDs. While nations abroad recognize the value of SLP involvement in all stages of processing for justice-involved youth (JIY), America lags in utilizing SLPs to improve JIY outcomes and lower youth's risk of …

Conceptions Of Heroic Leadership In Civil Society, Theresa A. Thorkildsen Mar 2024

Conceptions Of Heroic Leadership In Civil Society, Theresa A. Thorkildsen

Heroism Science

While nations face multiple disruptions to civil society, individuals in late adolescence and early adulthood are overlooked for heroic leadership opportunities in some cultures. An underestimation of individuals’ abilities is sometimes fostered by biological definitions of human development that align competence with physical changes in the brain (Blakemore, 2012). Prolonged exposure to such disregard can encourage individuals to restrict the information they notice, fostering distortion in the intentions that support leadership readiness (Pratkanis, 2007). Studies of individuals’ conceptions of how the world operates can improve leadership readiness if such evidence is used to verify that individuals notice essential information. Using …

Field Testing Of Gamma-Spectroscopy Method For Soil Water Content Estimation In An Agricultural Field, Sophia Becker, Trenton E. Franz, Tanessa Morris, Bailey Mullins Mar 2024

Field Testing Of Gamma-Spectroscopy Method For Soil Water Content Estimation In An Agricultural Field, Sophia Becker, Trenton E. Franz, Tanessa Morris, Bailey Mullins

School of Natural Resources: Faculty Publications

Gamma-ray spectroscopy (GRS) enables continuous estimation of soil water content (SWC) at the subfield scale with a noninvasive sensor. Hydrological applications, including hyper-resolution land surface models and precision agricultural decision making, could benefit greatly from such SWC information, but a gap exists between established theory and accurate estimation of SWC from GRS in the field. In response, we conducted a robust three-year field validation study at a wellinstrumented agricultural site in Nebraska, United States. The study involved 27 gravimetric water content sampling campaigns in maize and soybean and 40K specific activity (Bq kg−1) measurements from a stationary …

The Impact Of Kangaroo Care On The Weight Gain Of Premature Infants, Heather Vincequere Mar 2024

The Impact Of Kangaroo Care On The Weight Gain Of Premature Infants, Heather Vincequere

SACAD: Scholarly Activities

Premature birth remains a global health concern, affecting approximately 15 million infants annually (WHO, 2023). Kangaroo Care (KC), involving skin-to-skin contact between caregivers and infants, was developed as a promising intervention to mitigate the adverse effects of prematurity. This study aimed to investigate the impact of KC on weight gain among preterm infants in the neonatal intensive care unit (NICU) at Doctors Hospital of Augusta (DHOA). A quasi-experimental quantitative posttest-only design was employed, with eight preterm infants (< 37 weeks gestation) participating in KC for at least 30 minutes daily. Daily weight measurements were collected over a four-week period and compared to the expected weight gain for infants receiving traditional incubator care. Results revealed a statistically significant increase in weight gain among infants receiving KC compared to the historical average for infants in traditional incubator care (t (7) = 2.443, p = 0.022). A large effect size (Cohen's d = 0.864) further supported the significance of these findings. Despite limitations such as a small sample size and convenience sampling, this study emphasizes that KC enhances weight gain in preterm infants, thus improving overall health outcomes. Implementation of KC requires ongoing support from nurse leaders to ensure proper education and successful integration into routine care practices. Nonetheless, continued research with larger samples and improved randomization is warranted to fully understand the long-term benefits of KC in neonatal care settings.
