Individual Or Team Analyst Reports? The Organization Of Analyst Research Activities, Xia Chen, Ning Jia, Dan Wang

Research Collection School Of Accountancy

Given the importance of research resource allocation within brokerage firms, we examine key factors that influence the issuance of individual vs. team analyst reports. Using a comprehensive sample of analyst reports from China for the 2008-2021 period, we find that this decision is influenced by (1) the brokerage firm's client interests, whereby firms held by the brokerage firm's mutual fund clients and firms that are the brokerage firm's underwriting clients receive more team than individual reports from the brokerage firm, and (2) the nature of corporate events, whereby routine events receive more team reports and nonroutine events receive more individual …

“Everything Is A New Challenge For Each Of Us”: A Qualitative Exploration Of Elementary Newcomer Students’ And Families’ Lived Experiences Of Acclimating To U.S. Schooling, Maureen Margaret Medeiros

Social Justice in Educational Leadership EdD Dissertations

Newcomer students, defined as foreign-born children who have attended U.S. schools for less than three years, are entering U.S. schools in ever-increasing numbers. Schools are often the first institutions to welcome immigrants to local communities, and meeting the linguistic, socioemotional, and academic needs of newcomer students and their families is essential to their success. However, data on newcomers is not publicly accessible, which makes them not easily visible in the school system. Furthermore, newcomers may have socioemotional challenges due to their prior life experiences, the immigration process, and then the likely challenges of limited English fluency which can lead to …

Aggregator Zone Selection For Ev Smart Controls Based-On Ml Clustering Of Grid Strength, Distance, And Charging Homogeneity, Rosemary E. Alden, Sam H. Lowe Ii, Dan M. Ionel

Electrical and Computer Engineering Graduate Research

Smart electric vehicle (EV) charging control methods from a central utility hub often require communication infrastructure over a large service area of electric power distribution systems with a large number of nodes. Industry standards such as Open Charge Point Protocol (OCPP) 2.1 have evolved to include topologies for local controllers to the individual chargers, i.e. EV aggregator zones. A machine learning (ML) application of k-means clustering is proposed to establish zones for coordination of EV charging based on grid strength and EV owner decision-making to charge per day. Very large-scale distribution networks including the IEEE 123 and 8500 benchmark feeders …

Cluster-Based Volt/Var Optimization On A Utility Distribution Feeder With Forecasted Ev Penetration, Steven B. Poore, Grant M. Fischer, Rosemary E. Alden, Evan S. Jones, Aron Patrick, Dan M. Ionel

Electrical and Computer Engineering Graduate Research

With significant increase in EV adoption expected in the near future and the associated impacts on power systems, the effect of volt/var optimization (VVO) as the next step to conservation voltage reduction (CVR), requires reevaluation. Implementation of a cluster-based VVO control strategy employs a novel approach with machine learning (ML) load forecasting to reduce device adjustments through k-means clustering of contiguous time steps with similar active power load in which a single adjustment would be sufficient. The cluster-based VVO method is tested on a complex real world utility distribution feeder with 2,018 nodes, 8.65MW peak load, 9 capacitor banks (CBs), …

Mitigation Of Pm Eddy Current Losses Using Offset Windings In Coreless Afpm Machines, Matin Vatani, Diego A. Lopez Guerrero, John F. Eastham, Dan M. Ionel

Electrical and Computer Engineering Graduate Research

Permanent magnet eddy current losses can become substantial in coreless stator axial flux permanent magnet (AFPM) machines operating at high speeds and under high electric loading, potentially leading to elevated temperatures and an increased risk of demagnetization. This paper investigates the origins of these losses through a detailed harmonic analysis of the winding factor and introduces a mitigation strategy. The proposed method utilizes two-layer offset windings, effectively minimizing undesirable armature flux harmonics through harmonic interaction between the offset layers. Two cases are studied: one in which each stator layer is connected to a separate inverter and another in which both …

The Continuing Unevolving Model Of Decency, Kennedy V. Louisiana In Peril, Patrick S. Metze

Criminal Law Practitioner

Professor Metze reflects on Kennedy v. Louisiana in its part in the development of Eighth Amendment jurisprudence and how the Supreme Court initially used Kennedy to further our understanding of the limits of the Eighth Amendment. The Court recently avoided a meaningful discussion of how our society is maturing and evolving by acknowledging a purposeful effort of some to reflect modern beliefs in opposition to those who would interpret everything through an 18th-century prism. After a case-by-case analysis of how the Court has used Kennedy, it is apparent the conservative majority now on the Court has decided there is no …

The Growing Of Freedom, And The Participatory Methodology Of Gardening: An Account Of John Dewey’S Conception Of “Freedom”, Jessica Clare Soester

Center for Dewey Studies Essay Award

In this paper I argue that for American Pragmatist John Dewey, freedom is better understood as a verb or gerund— "freedom-ing." A distinctive dimension of Dewey’s conception of “freedom” is that part of having freedom is the participation in the achieving of it, a continual process—in Dewey’s account, freedom is never won for good but must be constantly re-won. Persons must have the opportunity of being a part of their creative activity—directing and understanding their activity. Without freedom we stagnate, we are left with empty dictates; we do not inquire, new paths are not disclosed, we don't generate new structures …

Maximum-Likelihood Estimation Of Glandular Fraction For Mammography And Its Effect On Microcalcification Detection, Bryce J. Smith, Joyoni Dey, Lacey Medlock, David Solis, Krystal Kirby

Faculty Publications

Breast tissue is mainly a mixture of adipose and fibro-glandular tissue. Cancer risk and risk of undetected breast cancer increases with the amount of glandular tissue in the breast. Therefore, radiologists must report the total volume glandular fraction or a BI-RADS classification in screening and diagnostic mammography. In this work, a Maximum Likelihood algorithm accounting for count statistics and scatter is shown to estimate the pixel-wise glandular fraction from mammographic images. The pixel-wise glandular fraction provides information that helps localize dense tissue. The total volume glandular fraction can be calculated from pixel-wise glandular fraction. The algorithm was implemented for images …

Our understanding of the γ-ray sky has improved dramatically in the past decade, however, the unresolved γ-ray background (UGRB) still has a potential wealth of information about the faintest γ-ray sources pervading the Universe. Statistical cross-correlations with tracers of cosmic structure can indirectly identify the populations that most characterize the γ-ray background. In this study, we analyze the angular correlation between the γ-ray background and the matter distribution in the Universe as traced by gravitational lensing, leveraging more than a decade of observations from the Fermi-Large Area Telescope (LAT) and 3 years of data from the Dark Energy Survey (DES). …

We report on IXPE and NuSTAR observations beginning 40 days after the 2024 outburst onset of magnetar 1E 1841−045, marking the first IXPE observation of a magnetar in an enhanced state. Our spectropolarimetric analysis indicates that both a blackbody (BB) plus double power-law (PL) and a double blackbody plus power-law spectral model fit the phase-averaged intensity data well, with a hard PL tail (Γ = 1.19 and 1.35, respectively) dominating above ≈5 keV. For the former model, we find the soft PL (the dominant component at soft energies) exhibits a polarization degree (PD) of ≈30% while the hard PL displays …
