The moduli space of stable quotients

A moduli space of stable quotients of the rank n trivial sheaf on stable curves is introduced. Over nonsingular curves, the moduli space is Grothendieck's Quot scheme. Over nodal curves, a relative construction is made to keep the torsion of the quotient away from the singularities. New compactifications of classical spaces arise naturally: a nonsingular and irreducible compactification of the moduli of maps from genus 1 curves to projective space is obtained. Localization on the moduli of stable quotients leads to new relations in the tautological ring generalizing Brill-Noether constructions. The moduli space of stable quotients is proven to carry a canonical 2-term obstruction theory and thus a virtual class. The resulting system of descendent invariants is proven to equal the Gromov-Witten theory of the Grassmannian in all genera. Stable quotients can also be used to study Calabi-Yau geometries. The conifold is calculated to agree with stable maps. Several questions about the behavior of stable quotients for arbitrary targets are raised.Comment: 50 page

Perspective Chapter: The Significance of Diversity, Equity, and Inclusion in Social Work Leadership

There tends to be consensus among leaders that the most significant resource of any social work organization is its staff. However, many social work organizations continuously pay little or no attention to staff diversity, equity, and inclusion. Leadership plays a crucial role in creating and sustaining a climate of diversity, equity, and inclusion in organizations. Valuing diversity, equity, and inclusion entails a process but should also be the goal of all social work organizations. Recruiting, training, retaining, supervising, and managing an organization’s human resources are ongoing responsibilities primarily undertaken by social work leaders. This chapter will explore the role of leaders in creating and sustaining diversity, equity, and inclusion throughout all facets of a social work organization. A description of what it means to lead a social work organization with diversity, equity, and inclusion including qualities demonstrated by a leader in this type of organization will be provided. The significance of a metric-driven approach with clear benchmarks to measure diversity, equity, and inclusion will be explored

Promotional Flyer for Exhibit - Rituals of Healing: Body, Mind, Spirit

Exhibit dates: Feb. 8 through April 20, 2023, Stuart and Mimi Rose Gallery and Marian Library Gallery, both in Roesch Library. Rose Gallery: University of Dayton first-year students in Professor Liz Hutter’s writing seminar curated this display of artifacts from the Marian Library collections. While practicing writing as a model of inquiry and discovery, students wrote narratives to explore what individuals or groups believe about religion, medical expertise, and healing of the body, mind and spirit. Marian Library Gallery: Materials included in this section of the exhibit feature Mary’s roles in health, healing and rituals — including tarot cards, Catalan goigs and Schluckbildchen. Additional themes include the intersection of Catholic rituals with other faiths and spiritualities, as well as the history of Our Lady of Health across regions and centuries

Self-reported use and perception of the L1 and L2 among maximally proficient bi- and multilinguals: a quantitative and qualitative investigation

This study investigates language preferences and perceptions in the use of the native language (L1) and second language (L2) by 386 bi- and multilingual adults. Participants declared that they were maximally proficient in L1 and L2 and used both constantly. A quantitative analysis revealed that despite their maximal proficiency in the L1 and L2, participants preferred to use the L1 for communicating feelings or anger, swearing, addressing their children, performing mental calculations, and using inner speech. They also perceived their L1 to be emotionally stronger than their L2 and reported lower levels of communicative anxiety in their L1. An analysis of interview data from 20 participants confirmed these findings while adding nuance. Indeed, differences in the use of the L1 and L2 and perceptions of both are often subtle and context-specific. Participants confirmed the finding that the L1 is usually felt to be more powerful than the L2, but this did not automatically translate into a preference for the L1. Longer stretches of time in the L2 culture are linked to a gradual shift in linguistic practices and perceptions. Participants reported that their multilingualism and multiculturalism gave them a sense of empowerment and a feeling of freedom

Quasi Anomalous Knowledge: Searching for new physics with embedded knowledge

Discoveries of new phenomena often involve a dedicated search for a hypothetical physics signature. Recently, novel deep learning techniques have emerged for anomaly detection in the absence of a signal prior. However, by ignoring signal priors, the sensitivity of these approaches is significantly reduced. We present a new strategy dubbed Quasi Anomalous Knowledge (QUAK), whereby we introduce alternative signal priors that capture some of the salient features of new physics signatures, allowing for the recovery of sensitivity even when the alternative signal is incorrect. This approach can be applied to a broad range of physics models and neural network architectures. In this paper, we apply QUAK to anomaly detection of new physics events at the CERN Large Hadron Collider utilizing variational autoencoders with normalizing flow.Comment: 25 pages, 9 figure

Chapter 12: Urban architecture for well-being: a design canvas for inclusive green cities

Landscape and urban planners, designers, as well as architects, can take up inclusive planning and design processes that acknowledge human needs and dignity, and foster participation in shared decision-making. Underpinning these processes are values of empathy, placation, accessibility, and identity essential to imagining and creating inclusive green cities. This chapter provides a deeper understanding of the different dimensions of an inclusive green city and how social equity is an integral part of any design effort. We begin by exploring our vision and the values necessary for green urban design. A framework for three aspects of equity – recognitional equity, procedural equity, and distributional equity – is presented with selected case studies that serve as evolving good practices for equitable green urban design. From this framework and resulting values, we built on a value-inclusive design canvas and present design principles that planners, designers and architects can adopt as their own

The emotional weight of "I love you" in multilinguals' languages

The present paper considers the perceived emotional weight of the phrase I love you in multilinguals’ different languages. The sample consists of 1459 adult multilinguals speaking a total of 77 different first languages. They filled out an on-line questionnaire with open and closed questions linked to language behavior and emotions. Feedback on the open question related to perceived emotional weight of the phrase I love you in the multilinguals’ different languages was recoded in three categories: it being strongest in (1) the first language (L1), (2) the first language and a foreign language, and (3) a foreign language (LX). A majority of speakers felt I love you was strongest in their L1. Participants offered various explanations for their perception. Statistical analyses revealed that the perception of weight of the phrase I love you was associated with self-perceived language dominance, context of acquisition of the L2, age of onset of learning the L2, degree of socialization in the L2, nature of the network of interlocutors in the L2, and self-perceived oral proficiency in the L2

Embodiment and emotional memory in first vs. second language

Language and emotions are closely linked. However, previous research suggests that this link is stronger in a native language (L1) than in a second language (L2) that had been learned later in life. The present study investigates whether such reduced emotionality in L2 is reflected in changes in emotional memory and embodied responses to L2 in comparison to L1. Late Spanish/English bilinguals performed a memory task involving an encoding and a surprise retrieval phase. Facial motor resonance and skin conductance (SC) responses were recorded during encoding. The results give first indications that the enhanced memory for emotional vs. neutral content (EEM effect) is stronger in L1 and less present in L2. Furthermore, the results give partial support for decreased facial motor resonance and SC responses to emotional words in L2 as compared to L1. These findings suggest that embodied knowledge involved in emotional memory is associated to increased affective encoding and retrieval of L1 compared to L2
