This study examines how product market competition differentially affects existing versus new analysts. I find that new analysts' coverage increase is significantly higher than the existing analysts' coverage increase when a portfolio firm faces high competition, suggesting existing analysts’ tendency to avoid competition among analysts for their career success. I also find that new analysts' one-year earnings forecasts accuracy decrease is significantly larger than the one of the existing analysts when the portfolio firm faces high competition. These findings indicate that existing analysts consider the situation firm faces, product market competition, and they are more competent than new analysts.

Black, Indigenous, and People of Color (BIPOC) women faculty and administrators are breaking barriers, maintaining excellence, becoming award-winning scholars, and flourishing as experts in their fields. Still, they must survive while they thrive, grappling with insecurity, writer’s block, and imposter syndrome. Further examination prompts the realization that imposter syndrome may be a scapegoat for structural racism. Moreover, COVID-19 has created substantial health and financial tolls, fueled mental and emotional fatigue, and disrupted workplace productivity. These barriers caused by COVID-19 and structural racism inspire the courage to reassure, uplift, mentor, invite, and make collaborative spaces for BIPOC women to express feelings of vulnerability, unease, and, ultimately, hope. When seats are missing at the table, one can bring their own table and seats. In a field of often unforgiving critics, the authors provided underrepresented scholars the opportunity to promote authenticity and illuminate their voices. This chapter shares the authors’ reflections on being able to share the diverse and resilient perspectives of BIPOC women in academia.

U.S. society has been gripped with dueling pandemics of racial and ethnic disparities in COVID-19 outcomes, highly publicized instances of police brutality against Black persons, and ensuing unrest to challenges these atrocities. In higher education, the rapid pivot response to COVID-19 with remote and virtual learning has also highlighted multiple levels of mental health trauma and disparities. There has also been vicarious trauma for Black women in academia who may have seen their family, friends, or loved ones reflected during increased media coverage of police brutality. This implores the need for effective strategies to mitigate these issues. This chapter discusses evidence-based strategies for Black women who navigate academia and teach during times of COVID-19 and social unrest. This chapter also proposes strategies for university leaders to consider alleviating cultural and racial gaps in the classroom or workplace and foster diversity and inclusion in academia.

When I first took the adverse childhood experiences (ACEs) quiz, I was overcome with the enormity of Black trauma contained in those ten questions. The quiz reflected my own story, as well as those of Black students, women, and families—traumas that were magnified by the impact of three pandemics: COVID-19, economic inequities, and systemic racism. The definition of trauma as “emotional responses to disastrous life events” like COVID-19 can have both short- and long-term health consequences throughout one’s lifespan. The impact of COVID-19 as Black trauma in my family will reverberate long after society heals from the last three years and moves toward living with COVID-19 symbiotically. It is imperative to recognize ACEs and their perpetual trauma to implement successful trauma-informed practices to counteract and undo the damaging effects of COVID-19 on our collective lives.

In addition to fueling health disparities, the COVID-19 pandemic has exacerbated inequities among faculty of color. COVID-19 has also taken a dramatic toll on college students’ mental health, with evident racial disparities. Gender inequality in research productivity has also been revealed, with women submitting fewer papers compared to men. This pandemic has created an opportunity, of sorts, to promote academic and career success among women and students of color in academia. Research has shown that mentorship and research opportunities improve chances for success among students of color in higher education. Faculty members can also progress personally and professionally from such collaborations. Still, students of color are not equally given opportunities to collaborate with faculty on research. This chapter shares perspectives and strategies from Black women faculty and graduate students regarding faculty-student research to promote academic and career success among faculty and students of color in academia.

COVID-19 brought me challenges and opportunities. I lost important people in this pandemic but also accomplished a lot. COVID-19 gave me a chance to soul search, grow, and develop. I blossomed into the woman I have always wanted to be but could not find. During it all, I was awarded my undergraduate degree, got accepted to a graduate program, received a new job, and bought my first car. With every blessing came a challenge, including health problems. Still, I persevered. Opportunities continue to present themselves and I seize them. Professional successes included publishing an article, presenting at a state public health conference, being featured in my university’s annual newsletter, and nailing my dream job! I got to “See Me!”, a woman of color coming from another country, accomplishing so much in a short span of time. This chapter details a true testimony and how giving up is not an option.

On Wednesday, January 20, 2021, Kamala Harris broke through the gender and racial barrier that has kept men at the top ranks of American politics for over two centuries. This moment singlehandedly challenged the definition of leadership and who “fits” in that traditional model. Reyes examines the challenges and highlights three lessons of leading in color in academia today, being the first Latina to chair her department. Her journey reflects similar experiences of women of color who are burdened by the emotional toll that comes with being a part of systemic change, by virtue of leading while of color. To begin dismantling systemic racism and sexism, organizations must commit to addressing the issues head-on by reexamining policies, practices, and work environments that have perpetuated systemic inequalities. Greater supports are needed for women of color to be effective as their contributions are invaluable in achieving true systemic change.

Being a millennial person-of-color in the twenty-first century is exhaustive in itself—adding the vulnerabilities of a global pandemic magnified that undertaking. As women, we bear the responsibilities of balancing our professional life with our family life; our role as a partner or friend with our role as an individual being; and our mental health with our social health. “Grow Through What You Go Through” explores the value of saying “Yes, I can do this too” when COVID-19 gave many a reason to say, “I’ve had enough.” Between being a supportive partner and family member to many who experienced financial and educational setbacks and being an important part of preparing the next set of future nurses to lead and excel during a global pandemic, COVID-19 enlightened my perspective on who I was at the start of COVID-19 and the person I would turn out to be by the end of it.

As a tenured professor at a predominantly white institution (PWI), I am aware of the hardships we face in the academy; as a mother of three Black girls, a wife to a Black man, I am full. And yet, I must make space to see my own self clearly. Each day as a Black woman, I must set the intention to save my own life.

This chapter provides a brief autobiographical account of her multiethnic and racial background as a Louisiana Creole in south Louisiana. The author points out that among all racial and ethnic groups in the United States, Indigenous people are the only ones that require some form of lineal Native American descent or blood quantum. The chapter provides an ancestry account of two American Indian tribes along the bayous of south Louisiana, the Chitimacha, and the United Houma Nation. While one federally recognized tribe has attempted to remove all relations to individuals of Black, Negro, or African American descent, the other has closed enrollment to new members (despite lineal descent), with the unifying factor among these communities being establishing progenitors. Finally, the author articulates how lack of access to resources related to issues such as COVID-19 has perpetuated the historical legacy of medical racism in tribal and underserved communities in the United States.

In this paper, we focus on improving the age estimation accuracy on smartphones. Estimating a smartphone user’s age has several applications such as protecting our children online by filtering age-inappropriate contents, providing a customized e-commerce experience, etc. However, accuracy of the the state-of-the-art age estimation techniques that use touch behavior on smartphones is still limited because of the lack of sufficient amount of training data. We perform rigorous experiments using zoom gestures on smartphones and demonstrate that increasing the amount of training data can significantly improve the age estimation accuracy. Based on the findings in this study, we recommend creating a large touch dynamics-based age estimation data set so that more accurate age estimation models can be built and in turn, can be used more confidently.

Over recent decades, research in Artificial Intelligence (AI) has developed a broad range of approaches and methods that can be utilized or adapted to address complex optimization problems. As real-world problems get increasingly complicated, this requires an effective optimization method. Various meta-heuristic algorithms have been developed and applied in the optimization domain. This paper used and ameliorated a promising meta-heuristic approach named Crow Search Algorithm (CSA) to address numerical optimization problems. Although CSA can efficiently optimize many problems, it needs more searchability and early convergence. Its positioning updating process was improved by supporting two adaptive parameters: flight length (fl) and awareness probability (AP) to tackle these curbs. This is to manage the exploration and exploitation conducts of CSA in the search space. This process takes advantage of the randomization of crows in CSA and the adoption of well-known growth functions. These functions were recognized as exponential, power, and S-shaped functions to develop three different improved versions of CSA, referred to as Exponential CSA (ECSA), Power CSA (PCSA), and S-shaped CSA (SCSA). In each of these variants, two different functions were used to amend the values of fl and AP. A new dominant parameter was added to the positioning updating process of these algorithms to enhance exploration and exploitation behaviors further. The reliability of the proposed algorithms was evaluated on 67 benchmark functions, and their performance was quantified using relevant assessment criteria. The functionality of these algorithms was illustrated by tackling four engineering design problems. A comparative study was made to explore the efficacy of the proposed algorithms over the standard one and other methods. Overall results showed that ECSA, PCSA, and SCSA have convincing merits with superior performance compared to the others.

Aphasia is a language disorder that occurs as a result of brain damage. It affects auditory comprehension, verbal expression, reading, and writing due to the disruption of specific language components such as phonology, semantics, and/or syntax. A hallmark characteristic of aphasia is anomia, or impaired word retrieval. This may occur in the context of fluent speech (normal rate, rhythm and prosody) or nonfluent speech (hesitant and agrammatic verbal output). Other characteristics of aphasia vary depending on the specific location and extent of brain damage. Alexia and agraphia are acquired impairments in reading and writing, respectively. These deficits may occur in isolation but more commonly co-occur with aphasia. Assessment and treatment of aphasia, alexia, and agraphia focuses on identifying and restoring impaired function as well as determining the impact of the impairment of quality of life and developing compensatory strategies to manage persisting deficits. This article describes the symptoms associated with aphasia, alexia, and agraphia, the subtypes and neurological correlates of each impairment, the general trajectory of recovery, and assessment and treatment approaches. © 2023 Elsevier Inc.

Global polarizations (P) of Λ (¯¯¯Λ) hyperons have been observed in noncentral heavy-ion collisions. The strong magnetic field primarily created by the spectator protons in such collisions would split the Λ and ¯¯¯Λ global polarizations (ΔP=PΛ−P¯¯¯Λ<0). Additionally, quantum chromodynamics predicts topological charge fluctuations in vacuum, resulting in a chirality imbalance or parity violation in a local domain. This would give rise to an imbalance (Δn=NL−NR⟨NL+NR⟩≠0) between left- and right-handed Λ (¯¯¯Λ) as well as a charge separation along the magnetic field, referred to as the chiral magnetic effect (CME). This charge separation can be characterized by the parity-even azimuthal correlator (Δγ) and parity-odd azimuthal harmonic observable (Δa1). Measurements of ΔP, Δγ, and Δa1 have not led to definitive conclusions concerning the CME or the magnetic field, and Δn has not been measured previously. Correlations among these observables may reveal new insights. This paper reports measurements of correlation between Δn and Δa1, which is sensitive to chirality fluctuations, and correlation between ΔP and Δγ sensitive to magnetic field in Au+Au collisions at 27 GeV. For both measurements, no correlations have been observed beyond statistical fluctuations.

The chiral magnetic wave (CMW) has been theorized to propagate in the deconfined nuclear medium formed in high-energy heavy-ion collisions and to cause a difference in elliptic flow (v2) between negatively and positively charged hadrons. Experimental data consistent with the CMW have been reported by the STAR Collaboration at the Relativistic Heavy Ion Collider (RHIC), based on the charge asymmetry dependence of the pion v2 from Au+Au collisions at √sNN=27 to 200 GeV. In this comprehensive study, we present the STAR measurements of elliptic flow and triangular flow of charged pions, along with the v2 of charged kaons and protons, as a function of charge asymmetry in Au+Au collisions at √sNN=27, 39, 62.4, and 200 GeV. The slope parameters extracted from the linear dependence of the v2 difference on charge asymmetry for different particle species are reported and compared in different centrality intervals. In addition, the slopes of v2 for charged pions in small systems, i.e., p+Au and d+Au at √sNN=200 GeV, are also presented and compared with those in large systems, i.e., Au+Au at √sNN=200 GeV and U+U at 193 GeV. Our results provide new insights for the possible existence of the CMW and further constrain the background contributions in heavy-ion collisions at RHIC energies.

In relativistic heavy-ion collisions, a global spin polarization, PH, of Λ and ¯¯¯Λ hyperons along the direction of the system angular momentum was discovered and measured across a broad range of collision energies and demonstrated a trend of increasing PH with decreasing √sNN. A splitting between Λ and ¯¯¯Λ polarization may be possible due to their different magnetic moments in a late-stage magnetic field sustained by the quark-gluon plasma which is formed in the collision. The results presented in this study find no significant splitting at the collision energies of √sNN=19.6 and 27 GeV in the BNL Relativistic Heavy Ion Collisions Beam Energy Scan Phase II using the STAR detector, with an upper limit of P¯¯¯Λ−PΛ<0.24% and P¯¯¯Λ−PΛ<0.35%, respectively, at a 95% confidence level. We derive an upper limit on the naive extraction of the late-stage magnetic field of B<9.4×1012 T and B<1.4×1013 T at √sNN=19.6 and 27 GeV, respectively, although more thorough derivations are needed. Differential measurements of PH were performed with respect to collision centrality, transverse momentum, and rapidity. With our current acceptance of |y|<1 and uncertainties, we observe no dependence on transverse momentum and rapidity in this analysis. These results challenge multiple existing model calculations following a variety of different assumptions which have each predicted a strong dependence on rapidity in this collision-energy range.

COVID-19 caused an increase in the demand for medications, which led to an increase in pharmaceutical waste and there is no doubt that this contributes to environmental pollution. Hence, it became necessary to search for how to protect and improve the environment by encouraging the behavior of medication waste reduction. Accordingly, this study aims to investigate the factors affecting intentions to reduce medication waste. Considering this, we develop an extended theory of planned behavior (TPB) framework by incorporating the constructs of moral obligation, environmental awareness, and medication waste risk perception. Using the convenience sampling method and based on a self-administered questionnaire, a total of 225 usable responses were collected in five Algerian cities. The results showed that positive attitudes (β = 0.316, p < 0.001), moral obligation (β = 0.291, p < 0.001), environmental awareness (β = 0.227, p < 0.001), perceived behavior control (PBC) (β = 0.151, p = 0.001), greater perceived risks (β = 0.127, p < 0.001), and subjective norm (β = 0.096, p < 0.05) significantly and positively influence the medication waste minimization intention. Furthermore, our analyses revealed that the extended TPB model explained 73.40% of the intention variance. In conclusion, we have explored the intentions, and there may be a gap between intent and actual behavior. Therefore, we recommend future studies to examine the factors affecting the actual behavior of medication waste reduction and to investigate environmental ethics and religious commitment as predictors of waste reduction intentions.

Monastic tonsure of citizens of the Russian Empire abroad became a particularly complex issue during the latter half of the nineteenth century, when Mt. Athos became a favorite destination of those interested in assuming the monastic habit outside the empire. The Russian authorities sought to control and regulate such tonsures by establishing procedures for checking their validity, and by ruling out automatic recognition of them in the empire. Individuals who were tonsured as monks abroad manipulated or tried to manipulate such regulations in order to facilitate travel back and forth from the Russian Empire for their own purposes. The result was that the real and apparent ambiguities that such rules allowed for were exploited by both state authorities and by real or fake monks themselves. The essay seeks to offer some perspectives on this phenomenon by focusing on four cases preserved in archival records. © 2023 Ltd "Integration: Education and Science". All rights reserved.
