Counting Girls In - Gender Issues in Science and Mathematics: An Examination of the Research Concerning Innate and Socio-Cultural Gender Differences in the Fields of Science and Mathematics in an Effort to Promote More Female Participation

In today\u27s world, there is an increasing demand for people in the technological fields. Fewer females than males pursue careers in physical sciences, engineering, and computer science in the United States presenting a loss of needed mathematicians and scientists. Gender differences related to mathematics and science is a complex arena of study, involving both innate biological differences combined with socially constructed ideas about gender in society. Through an in-depth investigation from educational, cognitive, and social psychology perspectives one will be able to determine how innate and socio-cultural factors contribute to the shortage of needed mathematicians and scientists in the United States

Dante Praedicator: Sermons and Preaching Culture in the Commedia

Starting from the premise that Dante takes influence from the sermons and preaching culture of his time in his construction of a voice of authority, this dissertation tracks the poet's use of sermonic material and rhetoric, as well as more explicit discussions on preaching through his entire corpus. Chapter One, "Dante Praedicator? Introduction to an Understudied Rhetorical Mode in the Commedia," elaborates on the argument that Dante the poet oftentimes acts as a preacher, and shows how this claim opens up new lines of inquiry into the poet's textuality. The first part of this chapter shows how the Commedia's early reception practically takes for granted that the poem is a sort of sermon, and supporting evidence shows in detail how the poem and preaching share much of the same subject matter, and demonstrates how the poem and sermons answer generic and stylistic questions in much the same way. The second section of this chapter surveys the last hundred years of Dante studies, to trace the roots of the recent critical prejudice against non-poetic influences on the poet's work - ranging from liturgy, Christian doctrine and preaching - and hypothesizes its source in Benedetto Croce's seminal 1921 essay, "La poesia di Dante," which rejects the idea of a didactic and hortatory Dante in order to focus instead on the poet qua poet. This vision of a secularized and emphatically "poetic" Dante became the status quo in Dante scholarship (although not without a few dissenters). Finally, the chapter summarizes some of the more recent work discovering the predicatory in Dante, and hypothesizes new questions about this textual mode in the Commedia, which the following chapters of this dissertation will discuss. Chapter Two, "Prohibition and Permission (with a Consideration of the Bolgia of Hypocrisy and Fra Dolcino)," explores the preaching of Dante's time. This chapter explains the social and historical circumstances around the 1214 legislation of Lateran IV, which ordered the ordainment of new preachers, and then recounts the thirteenth century renaissance of preaching as a means to propagate orthodoxy at a time when heresy threatened the Church's unity and stability. Because of this threat that heretical preaching had caused, the Church attempted to regulate preaching through prohibitions and permissions. The chapter then explores Dante's response to these legislative issues in the Commedia - specifically in his treatment of the hypocrites in Inferno 23, and of the schismatics and sowers of discord in Inferno 28. The chapter concludes by arguing that Dante responds to the mandates of church legislation with a considerable degree of indifference. On the one hand he highlights the failure of officials within the Church hierarchy who ought to preach, and on the other refuses to criticize the preaching of zealots that the Church censures as heretics on the other. After the previous chapter's exploration of Dante's relationship to preaching legislation, Chapter Three, "Predicante Iustitiam: Dante the Self-Authorizing Poet," explores more deeply what the poet means when he talks about preaching. The first part of this tripartite chapter proceeds philologically, examining first how Dante's poem consistently refuses to associate anyone identified as a "cherco," "prete," "pastor" or "sacerdote" with preaching, choosing instead to generally highlight the misdeeds of such figures. In this way the poet clears the pulpit of competition, aiming to situate himself, eventually, in that same role. The second part follows philologically as well, to examining variations on the word "predicare" as it occurs in the literature of Dante's milieu and in his own writing, and revealing its unique power as a word used to declare objective truths, though not without unique rhetorical overtones. Finally, the third section shows how Dante's careful use of "predicare" in his letters establishes himself as a preaching figure par excellence, who draws from the apostolic precedents established in the New Testament, as well as the prophetic and apocalyptic Noahic precedent as theorized in II Peter 2:5-7. Chapter Four, "Dicitur predicatio quandoque prophetia," continues where the previous chapter left off, with the suggestion that preaching and prophecy are in many cases one and the same thing. Taking a step away from the common contemporary belief in Dante studies that prophecy is generally something oriented towards forecasting events, this chapter uses Scripture, Aquinas's theology and the artes praedicandi in circulation in Dante's time to show how prophecy and preaching were understood to go hand in hand, well into the Middle Ages. Once this theoretical framework is established, the chapter proceeds to re-evaluate some of Dante's discussions on prophets in Paradiso, namely Nathan of the Old Testament and the twelfth century prophet Joachim of Fiore, to show that what Dante values as "prophetic" in these figures is also closely linked to their status as interpreters and preachers of divine truth, rather than any particular skills at forecasting (i.e. prophecy in the strict sense, according to contemporary standards). Chapters Five and Six mark a transition to a more focused analysis of preaching in the Commedia, to investigate Dante's sustained, but more subtle, use of the rhetorical techniques of preaching. Chapter Five, "The Art of Preaching in the Sphere of the Sun," examines the sequence of canti in Paradiso 10-13, to show the influence of the artes praedicandi on the rhetoric of these canti, and particularly on the speech of Thomas Aquinas, as Dante represents him here. An in-depth discussion of a form of preaching gaining influence in the duecento, sermo modernus, explains what it is, its component parts, and the way that it was used in Dante's world, and how it propagates a certain logical modes of thinking. Finally, Aquinas's speech in Paradiso 10-13 is examined for traces of sermo modernus, demonstrating that the poet intended to inflect Aquinas's language with predicatory valences, in the pursuit of a moral and ethical message that can be considered "authoritative." Chapter Six, "Beyond Sermo Modernus: Street Preaching in the Primum Mobile," turns to Beatrice's discourse in Paradiso 29, which combines complex theological discussion with a scabrous criticism of vainglorious street preaching. With language oscillating wildly between high and low registers, Beatrice rails against both the pseudoscience and philosophical ornament bogging down contemporary sermons, as well as the jests and buffooneries that less erudite street preachers employ to amuse their audience and extract favors and monetary compensation from them. It will be shown that here too the poet freely employs the language of the street, in echo of popular preachers of the time, and his willingness to embrace the physical and grotesque proves that his predicatory language is ultimately grounded in things, in the real. I will turn to examples from the life of St. Francis of Assisi to illustrate here his that his emphasis on things is represented not only in the preacher's words but also in his body, his acts, his example

Research seeks to expand new fishery

(...) In 1940, the ribbed mussels, Volsella demissus, of Tidewater Virginia were discovered by Du Pont chemists to be rich in this provitamin D. This discovery was followed immediately by the development of a mussel fishery on the Seaside of Virginia\u27s Eastern Shore peninsula, the activity centering on the large intertidal marshes where the mussels grow and in the shucking houses along the water fronts of shore towns where the mussels are steamed, shucked, and packed for shipment. This fishery has since constituted the country\u27s principal available provitamin D source, and large war demands for eggs and poultry meat have been met by the poultry industry with the help of the previously unexploited Virginia mussels. Because of the prospective importance of the mussel, the Du Pont company acted through the-Virginia Fisheries Laboratory in 1940 to initiate a biological study of this as yet little-known bivalve

Understanding the ecological and evolutionary consequences for plants following pollinator change

Pollinators are important drivers for angiosperm evolution and diversification, but it is not well understood how changes in the pollinator assemblage can affect plant evolution in the short term. To address this question, my thesis investigates the consequences for plants of the addition and removal of floral visitors for two flowering species, Digitalis purpurea and Nicotiana glauca, both of which recently colonised new continents and show variation in pollinators between their native and introduced ranges. In D. purpurea, I found that populations in the introduced range pollinated by a new functional group (hummingbirds) had larger proximal corolla tubes than in the native range. Together with directional selection observed for the trait in the introduced range, I demonstrate rapid evolution of proximal corolla tube traits following range expansion. Floral traits in this species show high heritabilities in all populations, in line with the ability to evolve rapidly. I also demonstrate that the addition of nectar robbers to D. purpurea plants, which are present in the introduced populations only, can cause significant negative effects on the female component of reproduction. In N. glauca, a plant pollinated by hummingbirds in the native range but self-pollinated in the introduced range, I found a relationship between stigma-anther distance and the rate of self-pollination in flowers but not at the level of the plant. I observed a high degree of within-individual variability for stigma-anther distances which may limit the response to selection for shorter stigma-anther distances to increase the rate of selfing. In this thesis, I show that the addition and removal of pollinators to the floral visitor assemblage of a plant can have consequences for floral trait evolution

Creating a Bigger Pie? The Effects of Employee Ownership, Profit Sharing, and Stock Options on Workplace Performance

This paper uses data from NBER surveys of over 40,000 employees in hundreds of facilities in 14 firms and from employees on the 2002 and 2006 General Social Surveys to explore how shared compensation affects turnover, absenteeism, loyalty, worker effort, and other outcomes affecting workplace performance. The empirical analysis shows that shared capitalism has beneficial effects on all outcomes save for absenteeism and that it has its strongest effects on turnover, loyalty, and worker effort when it is combined with: a) high-performance work policies (employee involvement, training, and job security), b) low levels of supervision, and c) fixed wages that are at or above market level. Most workers report that cash incentives, stock options, ESOP stock, and ESPP participation motivate them to work harder. The interaction of the effects of shared capitalism with other corporate policies suggests that the various shared capitalist and other policies may operate through a latent variable, "corporate culture".

Intensive glycemic treatment during Type 1 diabetes pregnancy: A story of (mostly) sweet success!

Studies from Scotland and Canada confirm large increases in the incidence of pregnancies complicated by pregestational type 1 diabetes (T1D). With this increased antenatal workload comes more specialization and staff expertise, which may be important as diabetes technology use increases. While euglycemia remains elusive and obstetrical intervention (earlier delivery, increased operative deliveries) is increasing, there have been some notable successes in the past 5–10 years. These include a decline in the rates of congenital anomaly (Canada) and stillbirths (U.K.) and substantial reductions in both maternal hypoglycemia (both moderate and severe) across many countries. However, pregnant women with T1D still spend ∼30–45% of the time (8–11 h/day) hyperglycemic during the second and third trimesters. The duration of maternal hyperglycemia appears unchanged in routine clinical care over the past decade. This ongoing fetal exposure to maternal hyperglycemia likely explains the persistent rates of large for gestational age (LGA), neonatal hypoglycemia, and neonatal intensive care unit (NICU) admissions in T1D offspring. The Continuous Glucose Monitoring in Women With Type 1 Diabetes in Pregnancy Trial (CONCEPTT) found that pregnant women using real-time continuous glucose monitoring (CGM) spent 5% less time (1.2 h/day) hyperglycemic during the third trimester, with clinically relevant reductions in LGA, neonatal hypoglycemia, and NICU admissions. This article will review the progress in our understanding of the intensive glycemic treatment of T1D pregnancy, focusing in particular on the recent technological advances in CGM and automated insulin delivery. It suggests that even with advanced diabetes technology, optimal maternal dietary intake is needed to minimize the neonatal complications attributed to postprandial hyperglycemia
