Women In Science, Technology, Engineering, And Math Professional Night For Youths, Emily N. Henry

Journal of Extension

Extracurricular science, technology, engineering, and math (STEM) activities are an engaging way to introduce historically-minoritized youths to STEM. In this article, I describe one such event, a Women in STEM Professional Night, designed to connect eighth-grade girls with women in STEM careers. This interactive event provides a personalized connection to STEM, helps combat gendered stereotypes, and builds girls’ self-identification with STEM. Best practices include a carefully structured event, inviting a diverse group of women STEM professionals, and intentional preparation of all participants to set expectations. These insights serve as a guide for Extension professionals interested in creating a similar event.

Using Competitors’ Data – A Role For Competition Law? Some Thoughts On The Amazon Marketplace Case, Iga Małobęcka-Szwast

Yearbook of Antitrust and Regulatory Studies

Based on the Commission’s investigation into Amazon’s practices, the article analyses whether Amazon’s use of sensitive data from independent retailers who sell via its marketplace may raise anticompetitive concerns and, if so, how they should be tackled, in particular, whether competition law is the right tool to address these concerns. Amazon’s conduct, which is being investigated by the Commission, does not easily fit in with well-established theories of harm. Therefore, it is proposed to develop new theories of harm that would be specifically tailored to challenges of digital markets and online platforms’ business models. Amazon’s conduct could be regarded as …

No Strings Attached? Zero-Price Practices On Social Media Markets Under Eu Abuse Of Dominance Assessment, Marta Sznajder

Yearbook of Antitrust and Regulatory Studies

Do customers pay too little when they pay nothing for accessing a social media platform ‘for free’, and/or do they pay too much? These ‘free’ online services attract customers even if they come at personal information or attention costs. As competition law traditionally focuses on positive prices, ‘free’ services raise the question whether and how they could be assessed as potentially harmful to competition and consumers. Thus, the aim of this paper is to discuss the extent to which EU competition law can be applied to evaluate unilateral abusive pricing practices of social media platforms providing ‘free’ services to customers. …

Although marinas and public ports provide the same services i.e., berthing services for nautical tourism vessels, different corporate tax regimes apply to these two types of seaports. The first part of the paper gives an overview of the legal rules regulating seaports in Croatia. Subsequently, the competitive positions of marinas and public ports …

How Much May An Unreasonable Delay Cost? Tar Lazio Annuls The Highest Sanction Ever Issued By The Italian Competition Authority, Zofia M. Mazur, Elisa Luna Scimeca

Yearbook of Antitrust and Regulatory Studies

The present contribution describes and comments on recent ruling(s) issued by the Italian Regional Administrative Court of Lazio Region (TAR Lazio) which annuls the highest sanction ever imposed by the Italian Competition Authority (AGCM) for the breach of competition law. The Court found that the AGCM’s final decision vitiated on both procedural and substantive grounds. The TAR Lazio held that the Competition Authority violated the principle of ‘reasonable length of proceedings’ by deferring the initiation of the investigation without valid justification. For this reason, in the last part of the contribution, the authors briefly analyse the possible consequences of the …

The Political Act Of Writing Feminism- Begum Rokeya Sakhawat Hossain And The Utopian Vision, Mashall Momin

Electronic Theses and Dissertations

Feminist Begum Rokeya Sakhawat Hossain lived a life of seclusion and oppression like many middle-class Muslim women in colonial India during the late nineteenth and early twentieth century. During this period, Rokeya used writing as a tool to fight against the oppression women faced from the patriarchal society and reimagined their gendered position in society. Rokeya wrote two novels, Sultana’s Dream and Padmarag, both set in feminist utopian societies. In these works, Rokeya expresses that the problem to the oppression of women can be traced to the purdah system or the seclusion of women, the solution is to grow …

Intra-Tumoral Nerve-Tracing In A Novel Syngeneic Model Of High-Grade Serous Ovarian Carcinoma, Jeffrey L Barr, Allison Kruse, Anthony C Restaino, Natalia Tulina, Sarah Stuckelberger, Samuel J Vermeer, Caitlin S Williamson, Daniel W Vermeer, Marianna Madeo, Jillian Stamp, Maria Bell, Mark Morgan, Ju-Yoon Yoon, Marilyn A Mitchell, Anna Budina, Dalia K Omran, Lauren E Schwartz, Ronny Drapkin, Paola D Vermeer

Faculty, Staff and Student Publications

Dense tumor innervation is associated with enhanced cancer progression and poor prognosis. We observed innervation in breast, prostate, pancreatic, lung, liver, ovarian, and colon cancers. Defining innervation in high-grade serous ovarian carcinoma (HGSOC) was a focus since sensory innervation was observed whereas the normal tissue contains predominantly sympathetic input. The origin, specific nerve type, and the mechanisms promoting innervation and driving nerve-cancer cell communications in ovarian cancer remain largely unknown. The technique of neuro-tracing enhances the study of tumor innervation by offering a means for identification and mapping of nerve sources that may directly and indirectly affect the tumor microenvironment. …

Quantitative Stem: A Method For Measuring Temperature And Thickness Effects On Thermal Diffuse Scattering Using Stem/Eels, And For Testing Electron Scattering Models, Paul S. Minson

Theses and Dissertations

In the last two decades, advances in the dark field detectors and microscopes of scanning transmission electron microscopy (STEM) have inspired a resurgence of interest in quantitative STEM analysis. One promising avenue is the use of STEM as a nanothermometric probe. In this application, thermal diffuse scattering, captured by a CCD camera or an annular dark field detector, acts as an indirect measurement of the specimen temperature. One challenge with taking such a measurement is achieving adequate sensitivity to quantify a change in scattered electron signal on the order of 1% or less of the full electron beam. Another difficulty …

Modulation Of Effector Gene Expression In The Blood-Feeding Arthropods Cimex Lectularius Linnaeus, (Hemiptera: Cimicidae) And Aedes Albopictus Skuse, (Diptera: Culicidae), Travis C. Van Warmerdam

Theses and Dissertations

Hematophagy, or blood-feeding behavior, has independently evolved multiple times in the class Insecta and results in the transmission of vector-borne parasites, bacteria and viruses causing 17% of all infectious diseases and over 700,000 human deaths annually. One of the major challenges in studying the discrete mechanisms involved in host-response to hematophagy or the host seeking behavior of hematophagous insects, is the vast amount of signaling processes and genes that are inextricably tied to these interactions. These experiments used the clustered regularly interspersed short palindromic repeat (CRISPR)/CRISPR-associated (Cas) and dsRNA knock-down technologies to examine mechanisms of immunological reactivity and host-seeking behavior. …

Evaluation Of The Utility And Performance Of An Autonomous Surface Vehicle For Mobile Monitoring Of Waterborne Biochemical Agents, Jessica Simmerman Wolfe

Theses and Dissertations

Real-time water quality monitoring is crucial due to land utilization increases which can negatively impact aquatic ecosystems from surface water runoff. Conventional monitoring methodologies are laborious, expensive, and spatio-temporally limited. Autonomous surface vehicles (ASVs), equipped with sensors/instrumentation, serve as mobile sampling stations that reduce labor and enhance data resolution. However, ASV autopilot navigational accuracy is affected by environmental forces (wind, current, and waves) that can alter trajectories of planned paths and negatively affect spatio-temporal resolution of water quality data. This study demonstrated a commercially available solar powered ASV equipped with a multi-sensor payload ability to operate autonomously to accurately and …

A Longitudinal Analysis Of Pathways To Computing Careers: Defining Broadening Participation In Computing (Bpc) Success With A Rearview Lens, Mercy Jaiyeola

Theses and Dissertations

Efforts to increase the participation of groups historically underrepresented in computing studies, and in the computing workforce, are well documented. It is a national effort with funding from a variety of sources being allocated to research in broadening participation in computing (BPC). Many of the BPC efforts are funded by the National Science Foundation (NSF) but as existing literature shows, the growth in representation of traditionally underrepresented minorities and women is not commensurate to the efforts and resources that have been directed toward this aim.

Instead of attempting to tackle the barriers to increasing representation, this dissertation research tackles the …

Urban-Rural Differences In Lifespan Variation In The United States, Benjamin H. Walker

Theses and Dissertations

Since the mid-1980s, mortality rate improvements in urban areas have outpaced those in rural areas, leading to substantial urban-rural disparities in mortality. Research on urban-rural mortality disparities has focused exclusively on differences in mortality between urban and rural areas and has not examined differences in the amount of inequality in the length of life within these areas. Lifespan variation is an important dimension of health inequality that complements traditional metrics of mortality (i.e., mortality rates and life expectancy) by indicating the amount of inequality of lifespans within a population. This dissertation provides several contributions to our understanding of urban-rural differences …
