Identification And Inference In First-Price Auctions With Risk Averse Bidders And Selective Entry, Xiaohong Chen, Matthew Gentry, Tong Li, Jingfeng Lu Aug 2020

Identification And Inference In First-Price Auctions With Risk Averse Bidders And Selective Entry, Xiaohong Chen, Matthew Gentry, Tong Li, Jingfeng Lu

Cowles Foundation Discussion Papers

We study identification and inference in first-price auctions with risk averse bidders and selective entry, building on a flexible entry and bidding framework we call the Affiliated Signal with Risk Aversion (AS-RA) model. Assuming that the econometrician observes either exogenous variation in the number of potential bidders (N) or a continuous instrument (z) shifting opportunity costs of entry, we provide a sharp characterization of the nonparametric restrictions implied by equilibrium bidding. Given variation in either competition or costs, this characterization implies that risk neutrality is nonparametrically testable in the sense that if bidders are strictly risk averse, then no risk …

International Journal of Management, Finance and Accounting

Malaysia, a fast-growing developing country in Asia, has envisioned Shared Prosperity Vision 2030 to become a developed economy with highincome via sustainable and inclusive economic growth by the year 2030. To accomplish this vision, femalelabour participation isneeded as the femalepopulation constitutesalmost half of Malaysia’s total population. However, female labour participation rate iswaylower than Malaysia’s overall labour force participation rate.The relatively low female labour participation rate can be a barrier to Malaysia’s economic development and thus the realization of its goal of a high income nation.Therefore, this paper makes an attempt to examine empirically the long-run causal association amongfemale labour force …

Vulnerabilities To Online Social Network Identity Deception Detection Research And Recommendations For Mitigation, Max Ismailov, Michail Tsikerdekis, Sherali Zeadally

Information Science Faculty Publications

Identity deception in online social networks is a pervasive problem. Ongoing research is developing methods for identity deception detection. However, the real-world efficacy of these methods is currently unknown because they have been evaluated largely through laboratory experiments. We present a review of representative state-of-the-art results on identity deception detection. Based on this analysis, we identify common methodological weaknesses for these approaches, and we propose recommendations that can increase their effectiveness for when they are applied in real-world environments.

Comparison Of Longitudinal Changes In Resting State Functional Magnetic Resonance Imaging Between Alzheimer’S And Healthy Controls, Berk Can Yilmaz

Theses

Resting State Functional Magnetic Resonance Imaging (rs-fMRI) is a technique that is widely used for analyzing brain function using different approaches and methods. This study involves rs-fMRI analysis of Blood Oxygenation Level Dependent (BOLD) signals acquired from Alzheimer’s disease (AD) Patients and Healthy Controls (HC). Each subject in the study had both functional and anatomical images with at least one rs-fMRI scan with their Anatomical (T1) scans. Previous rs-fMRI studies have demonstrated that AD shows differences in Amplitude of Low Frequency (<0.1 Hz) Fluctuations (ALFF), and Regional Homogeneity (ReHo) measures according to HCs.

The aim of the study is to investigate individual and group level differences using ReHo and mALFF related …

"Made Of Queer Magic": Understanding The Experiences Of Pregnancy For Queer Women, Lindsey Rogers Aug 2020

"Made Of Queer Magic": Understanding The Experiences Of Pregnancy For Queer Women, Lindsey Rogers

Doctoral Dissertations

Queer families are deciding to use donor insemination or medically assisted reproductive treatments to become pregnant and start their families. Previous research indicates that the process of using medically assisted reproductive treatments may be a stressful experience for queer families due to cisheteronormativity within the system. In addition, research has also revealed that stress during the process of conceiving can impact mental health experiences during pregnancy. However, there is a lack of research on the specific mental health experiences of pregnancy for queer women. The present study used a qualitative research design guided by constructivist grounded theory to examine the …

Evaluation Of Anthropometric Parameters Of Central Obesity Among Professional Drivers: A Receiver Operating Characteristic Analysis, Muhammad Asif, Muhammad Aslam, Saima Altaf, Abdul Majid, Saima Atif

Kesmas

Different anthropometric parameters have been proposed for assessing central obesity. The diagnostic performance of these anthropometric parameters and their ability to correctly measure central obesity for the professional community, like drivers, is questionable and needs to be assessed. The study aimed to examine the diagnostic performance of anthropometric parameters as indicators of central obesity in drivers as measured by waist circumference (WC) and to determine the best cut-off values for these parameters that would identify obese drivers. Anthropometric measurements from a cross-sectional sample of 197 professional drivers were taken under standard protocol. Receiver operating characteristics (ROC) analysis was used to …

Exploring The Relationship Between Children’S Vocabulary And Their Understanding Of Cardinality: A Methodological Approach, Justin Slifer, Emily Carrigan, Kristin Walker, Marie Coppola Aug 2020

Exploring The Relationship Between Children’S Vocabulary And Their Understanding Of Cardinality: A Methodological Approach, Justin Slifer, Emily Carrigan, Kristin Walker, Marie Coppola

Honors Scholar Theses

Is there a relationship between vocabulary and children’s understanding of cardinality? Does the way in which we classify cardinality data as tested by the Give-a-Number task affect finding such a relationship? This thesis explored these questions using a methodological approach, by testing the relationship between children’s receptive vocabulary scores and Give-a-Number scores classified in two different ways, the traditional knower-level assessment, as well as by calculating the proportion of trials answered correctly. A significant correlation was found between participants’ receptive vocabulary scores and Give-a-Number scores using both manners of classification, independent of the children’s ages. The results were compared with …

Challenge, Fantasy, And Curiosity: Activating Students' Intrinsic Motivation Within Information Literacy Sessions, Brandon West, Alan Witt

Milne Library

Student engagement is a consistent challenge for librarians in information literacy instruction, especially in the context of single session learning. Two librarians at a small, public liberal arts college took inspiration from Malone’s (1981) theory of intrinsically motivating instruction to create a lesson plan that caught the imagination of the students and produced enthusiastic participation. This paper explains the theoretical framework used, examines the reasons for its success in this iteration, and discusses potential applications to other information literacy lessons.

Bleaching is a well-known esthetic dental treatment performed to lighten the tooth shade. Among different cosmetic dental procedures, including direct and indirect tooth-colored restorations, bleaching is likely the most conservative approach. Bleaching has been accepted well by patients and proven as a safe and effective approach. Objective: Tooth bleaching can be conducted at home or in offices. This study was performed to compare the enamel microhardness before bleaching and one and eight weeks after the application of different bleaching agents. Methods: Forty human premolars were randomly divided into four groups, and their buccal surface underwent a Vickers microhardness test …
