The Impact Of Effective Leadership In Cross-Functional New Product Development Virtual Teams, Obianuju Obiano

Engineering and Technology Management Student Projects

The emergence of covid-19 has forced a lot of companies to move to virtual remote work. New product development cross-functional teams who meet often or few times in a year are now compelled to transition fully into virtual remote workplace. The question is how they can function effectively with maximum performance as they did in the traditional environment. This paper's main objective of this paper is to investigate and understand how effective leadership management can influence performance, conflict, and knowledge sharing while enhancing cross-functional new product development virtual teams. An in-depth analysis of literature has been conducted in this to …

Strategic Management Of Digital Contact Tracing Technologies: Covid-19 And Singapore, Yaya Sirimongkarakorn

Engineering and Technology Management Student Projects

The emergence of the COVID-19 virus and global health pandemic has sparked a rapid need for new digital solutions. Singapore took a strategic lead by paving the path towards innovating digital contact tracing (DCT) technologies to contain the spread of the virus. The nation’s expedited response and model for DCT has shown to be one that many countries can take example from, regardless of experiencing hurdles in gaining sufficient user uptake initially. The concerns surrounding data security and privacy has fueled the movement for DCT technologies. With the vast majority of the population being involved, many aspects need to be …

It hardly needs to be said that 2020 was a difficult year for the world. COVID-19 has infected over 120 million people and killed over 2 million as of March 2021 (Johns Hopkins). At the same time, police violence against people of color continues, even as communities engage in long-overdue reckoning initiatives. Across the globe, researchers, governments, and communities needed quick, open, up-to-date information on testing for, treating, and preventing COVID-19. Our increased dependence on technology during lockdowns provided some with safety and continuity, while others experienced the widening of the digital divide. There is no greater urgency than the …

Exclusion Statistics For Particles With A Discrete Spectrum, Stéphane Ouvry, Alexios P. Polychronakos

Publications and Research

We formulate and study the microscopic statistical mechanics of systems of particles with exclusion statistics in a discrete one-body spectrum. The statistical mechanics of these systems can be expressed in terms of effective single-level grand partition functions obeying a generalization of the standard thermodynamic exclusion statistics equation of state. We derive explicit expressions for the thermodynamic potential in terms of microscopic cluster coefficients and show that the mean occupation numbers of levels satisfy a nesting relation involving a number of adjacent levels determined by the exclusion parameter. We apply the formalism to the harmonic Calogero model and point out a …

Wavefront-Selective Fano Resonant Metasurface, Adam C. Overvig, Andrea Alù

Publications and Research

Fano resonances are conventionally understood as sharp spectral features with selectivity in the momentum-frequency domain, implying that they can be excited only by plane waves with specific frequencies and incident angles. We demonstrate that Fano resonances can be made generally selective in the space-frequency domain. They can be tailored to resonate only when excited by a frequency, polarization, and wavefront of choice. This generalization reveals that Fano systems are characterized by eigenwaves that scatter to their time-reversed image upon reflection. Although in conventional Fano systems this trivially occurs for normally incident plane waves, we show that, in general, the selected …

The Association Of Pregnancy Control, Emotions, And Beliefs With Pregnancy Desires, Meredith G. Manze, Diana R. Romero, Prabal De, Josette Hartnett, Lynn Roberts

Publications and Research

Context

Standard pregnancy intentions measures do not always align with how people approach pregnancy. Studies that have investigated beyond a binary framework found that those with “ambivalent” feelings towards pregnancy are less likely to use contraception consistently, but the reasons for this are unclear. We sought to gain a nuanced understanding of pregnancy desires, and how perceptions about pregnancy are associated with contraceptive use.

Methods

We used non-probability quota sampling based on sex, age, and geographic region for a web-based survey of heterosexual men and women, aged 21–44 years, who could become pregnant/impregnate and were not currently pregnant (n = …

Human Retinal Organoids Release Extracellular Vesicles That Regulate Gene Expression In Target Human Retinal Progenitor Cells, Jing Zhou, Miguel Flores‑Bellver, Jianbo Pan, Alberto Benito‑Martin, Cui Shi, Onyekwere Onwumere, Jason Mighty, Jiang Qian, Xiufeng Zhong, Tasmim Hogue, Baffour Amponsah‑Antwi, Linda Einbond, Rajendra Gharbaran, Hao Wu, Bo‑Juen Chen, Zhiliang Zheng, Tatyana Tchaikovskaya, Xusheng Zhang, Hector Peinado, Maria Valeria Canto‑Soler, Stephen Redenti

Publications and Research

The mechanisms underlying retinal development have not been completely elucidated. Extracellular vesicles (EVs) are novel essential mediators of cell‑to‑cell communication with emerging roles in developmental processes. Nevertheless, the identification of EVs in human retinal tissue, characterization of their cargo, and analysis of their potential role in retina development has not been accomplished. Three‑dimensional retinal tissue derived from human induced pluripotent stem cells (hiPSC) provide an ideal developmental system to achieve this goal. Here we report that hiPSC‑derived retinal organoids release exosomes and microvesicles with small noncoding RNA cargo. EV miRNA cargo‑predicted targetome correlates with Gene Ontology (GO) pathways involved in …

Framing Inclusion: The Media Treatment Of Irregular Immigrants' Right To Health Care In Spain, Alisa Petroff, Anahí Viladrich, Sònia Parella

Publications and Research

With the passing of Royal Decree-Law 16/2012, Spain’s national health system switched from a model defined by universal and free health care principles, to a private insurance system that excluded large population groups. Based on a qualitative research design, this paper examines the media treatment of undocumented immigrants’ prerogatives to public health care in Spain (2012–2018). The analysis of 234 articles, drawn from three major Spanish newspapers, reveals three frames that underscore the media’s "rhetorics of inclusion," which argue for the extension of free medical services to irregular immigrants a topic traditionally underestimated by the literature. The moralist frame, supported …

Understanding The Relationship Between Weather Variables, Dry Matter Intake, And Average Daily Gain Of Beef Cattle, Mustapha Yusuf

Animal Sciences

The current National Academies of Sciences, Engineering and Medicine (NASEM) dry matter intake (DMI) prediction models are inadequate for DMI prediction of beef cattle in the Northern Great Plains. Four studies were conducted to account for additional variation in DMI and average daily gain (ADG) caused by weather variables. Experiment 1 and 2 had 13,895 steer-weeks observations, experiment 3 had 13,739 steer-weeks observations, and experiment 4 had 2,161 cow-weeks observations, respectively. Experiment 1 examined the influence of ambient temperature and solar radiation on DMI of beef steers. In experiment 2, 3, and 4, we examined the influence of ambient temperature, …

Nature's Rights, Christiana Ochoa

Articles by Maurer Faculty

Do forests and rivers possess standing to sue? Do mountain ranges have substantive rights? A recent issue of The Judges’ Journal, a preeminent publication for American judges, alerts the bench, bar, and policymakers to the rapidly emerging “rights of nature,” predicting that state and federal courts will increasingly see claims asserting such rights. Within the United States, Tribal law has begun to legally recognize the rights of rivers, mountains, and other natural features. Several municipalities across the United States have also acted to recognize the rights of nature. United States courts have not yet addressed the issue, though in 2017, …

Distress And Resilience In Resettled Refugees Of War: Implications For Screening, Michael Hollifield, Eric C. Toolson, Sasha Verbillis-Kolp, Beth Farmer, Junko Yamazaki, Tsegaba Woldehaimanot, Annette Holland

School of Social Work Faculty Publications and Presentations

There is little work published about predictors of specific trajectory types of distress in refugees of war during early resettlement in a host country. Data about distress (Refugee Health Screener—15 (RHS-15)) and possible predictors of distress were collected at the domestic medical examination (T1) within 90 days of arrival and the civil surgeon examination (T2) 11–16 months after T1 for refugee groups from three countries (COU). Descriptive, correlative, analyses of variance, and regression techniques were used to determine trajectory type and their predictors. A higher percentage (7.3%) were distressed at T2 than at T1. By group, the Bhutanese became more …

“We’Re More Than A Daycare”: Reported Roles And Settings For Early Childhood Professionals And Implications For Professionalizing The Field, Rachel E. Schachter, Qingyu Jiang, Shayne B. Piasta, Erin E. Flynn

School of Social Work Faculty Publications and Presentations

In the US, recent efforts have focused on professionalizing the field of early childhood. One way to indicate professionalism is through the terms used to describe both the field and the workers. However, few have examined how practitioners or researchers describe early childhood professionals’ work. Using multiple data sources and analytic strategies, we examined the ways that those working with young children described their role and setting, as well as how these were described in research and practitioner journals. “Teacher” was the preferred term for both journals and professionals, and terms for setting reflected traditional K-12 school structures. Professionals linked …

Beyond “No”: Best Practices For Responding To Resource Requests, Kerry Wu

Library Faculty and Staff Publications and Presentations

At a recent BRASS Virtual Discussion, business librarians commiserated over the shared frustration of having to say “no” regularly to resource requests (RUSA_BRASS, n.d.). As a midcareer business librarian, I still feel the discomfort after having said “no” numerous times. In this article, I will share some of the practices I have found helpful in responding to requests from business faculty for new databases or journals, especially when I have to say “no” without burning bridges.

Acceptability Of An Intervention To Promote Viral Suppression And Serostatus Disclosure For Men Living With Hiv In South Africa: Qualitative Findings, Mxolisi Mathenjwa, Hazar Khidir, Cecilia Milford, Nzwakie Mosery, Letitia Rambally Greener, Madeline Pratt, Kasey O’Neil, Abigail Harrison, David R.

Men living with HIV ( MLWH ) often have reproductive goals that can increase HIV-transmission risks to their pregnancy partners. We developed a safer conception intervention for MLWH in South Africa employing cognitive behavioral skills to promote serostatus disclosure, ART uptake, and viral suppression. MLWH were recruited from an HIV clinic near Durban, South Africa, and encouraged to include partners in follow-up visits. Exit in-depth interviews were conducted with eleven men and one female partner. The emerging over-arching theme is that safer conception care mitigates internalized and community-level HIV-stigma among MLWH. Additional related sub-themes include: ( 1 ) safer conception …

Women Of Color Faculty Reimagining Institutional Spaces During The Covid-19 Pandemic, Marie Lo, Patti Duncan, Reshmi Dutt-Ballerstadt

English Faculty Publications and Presentations

As women of color faculty who have experienced challenges associated with hostile work environments within predominantly white institutions, we consider the ways that working remotely during COVID-19 offers transformative possibilities for reimagining our relationship to the academy. We discuss our embodied responses to institutional spaces that often marginalize faculty of color; how university leadership may be reimagined through a blurring of gendered, racialized lines of “public” and “private” (or institutional and domestic) spaces; and the possibility of healing from the trauma associated with oppressive workplaces and institutional betrayals.

Is Digital Humanities Adjuncting Infrastructurally Significant?, Kathi Inman Berens

English Faculty Publications and Presentations

This essay examines the infrastructural causes of digital humanities adjunct invisibility and proposes two remedies: to motivate DH adjunct self-identification by convening DH adjunct-specific prizes and bursaries; and what I call "microbenefactions": small actions by senior faculty that extend opportunities to adjuncts that cost little effort and can give adjuncts access to payment, prize-worthy work opportunities, or other benefits. The unspoken assumption is that DH skills are so much in demand that people with these skills are protected from adjuncting. As I interviewed seven DH adjuncts, their heterogeneous responses to standard questions reminded me that happy families are all alike; …

The purpose of this essay is to share the voices of EdD graduates who are often underrepresented or missing in the literature. To begin, we invited EdD graduates to co-author this article about the connection among their EdD program experiences and interactions and their activism. We included our definition of activism and posed three open-ended questions. Six program graduates and one professor agreed to organize the graduates’ responses by the question topics and salient themes. We asked about our experiences in the EdD program and how these influence—positively and negatively—what we are doing now (post-program). We found (a) relationships with …

Incarcerated Activism During Covid-19, M. Eve Hanan

Scholarly Works

Incarcerated people have a notoriously difficult time advocating for themselves. Like other authoritarian institutions, prisons severely curtail and often punish speech, organizing, and self-advocacy. Also, like other authoritarian institutions, prison administrators are inclined to suppress protest rather than respond to the grounds for protest. Yet, despite impediments to their participation, incarcerated people have organized during the pandemic, advocating for themselves through media channels, public forums, and the courts. Indeed, a dramatic increase in incarcerated activism correlates with the onset of the COVID-19 pandemic.

Just as the COVID-19 pandemic highlights injustice in other areas of criminal legal practices, it reveals both …
