Curse Of Democracy: Evidence From The 21st Century, Yusuke Narita, Ayumi Sudo

Cowles Foundation Discussion Papers

Democracy is widely believed to contribute to economic growth and public health. However, we find that this conventional wisdom is no longer true and even reversed; democracy has persistent negative impacts on GDP growth since the beginning of this century. This finding emerges from five different instrumental variable strategies. Our analysis suggests that democracies cause slower growth through less investment, less trade, and slower value-added growth in manufacturing and services. For 2020, democracy is also found to cause more deaths from Covid-19.

Research exposes students and lecturers to the availability of information resources for research. Students require quality information resources in order to conduct research. Libraries are meant to serve the students, lecturers and other members of the university community. However, libraries have been the source of keeping and disseminating information through books, journals, maps and other resources that are used by students and lecturers in the universities. The need of library resources and services is indispensable to students in order to achieve their set goals. Hence, this study evaluated the information needs and constrains that hinder use of library resources and …

Use Of Library Resources And Services Among Undergraduates In Nigerian Universities, Christy Olabisi Adeeko, Airen Adetimirin

Library Philosophy and Practice (e-journal)

Abstract

University libraries are established to meet the information needs of the university communities of which undergraduates constitute a significant portion. However, literature has shown that the level of use of the university libraries by the undergraduates is relatively low despite all the funds expended on library resources and services. This study, therefore, was designed to evaluate the level of use library resources and services by undergraduates in federal universities in the North-central, Nigeria. The five conventional federal universities in the North-central zone of Nigeria were enumerated while three homogenous faculties and six departments were purposively selected to give a …

This model may be used as a baseline by which to measure individual organizational performance, to measure performance …

Microbial Find, Inform, And Test Model For Identifying Spatially Distributed Contamination Sources: Framework Foundation And Demonstration Of Ruminant Bacteroides Abundance In River Sediments, Corinne Wiesner-Friedman, Rachelle E. Beattie, Jill R. Stewart, Krassimira R. Hristova, Marc L. Serre

Biological Sciences Faculty Research and Publications

Microbial pollution in rivers poses known ecological and health risks, yet causal and mechanistic linkages to sources remain difficult to establish. Host-associated microbial source tracking (MST) markers help to assess the microbial risks by linking hosts to contamination but do not identify the source locations. Land-use regression (LUR) models have been used to screen the source locations using spatial predictors but could be improved by characterizing transport (i.e., hauling, decay overland, and downstream). We introduce the microbial Find, Inform, and Test (FIT) framework, which expands previous LUR approaches and develops novel spatial predictor models to characterize the transported contributions. We …

Experiences Of Undergraduates And Graduate Teaching Assistants In Biology Course-Based Undergraduate Research Experiences, Emma Crystal Goodwin

Dissertations and Theses

Evidence of positive student outcomes from course-based undergraduate research experiences (CUREs) has sparked implementation of CUREs in introductory biology laboratory courses, as one approach to boosting student engagement in research. In a CURE, students collaborate with other students and instructors on a research project, where they conduct novel scientific research that has relevance to a local or scientific community. However, previous research rarely considers that graduate teaching assistants (GTAs) often teach introductory labs. The classroom role of GTAs expands in a CURE--they no longer need to simply teach a lab class, but also to serve as research mentors. GTAs, who …

Polyploid Giant Cancer Cells And Ovarian Cancer: New Insights Into Mitotic Regulators And Polyploidy†

Faculty, Staff and Students Publications

Current first-line treatment of patients with high-grade serous ovarian cancer (HGSOC) involves the use of cytotoxic drugs that frequently lead to recurrent tumors exhibiting increased resistance to the drugs and poor patient survival. Strong evidence is accumulating to show that HGSOC tumors and cell lines contain a subset of cells called polyploidy giant cancer cells (PGCCs) that act as stem-like, self-renewing cells. These PGCCs appear to play a key role in tumor progression by generating drug-resistant progeny produced, in part, as a consequence of utilizing a modified form of mitosis known as endoreplication. Thus, developing drugs to target PGCCs and …

Craniometric Analysis Of European Rabbit (Oryctolagus Cuniculus) Breeds To Trace Out Intraspecific And Inter Gender Morphometric Variations, Muhammad Rizwan, Rana Manzoor Ahmad, Abdul Majid Khan, Misbah Khalid, Muhammad Wajid

Journal of Bioresource Management

The family Liproidae expresses the significant variation of morphometric features at species level. In already available literature on the European rabbit (Oryctolagus cuniculus) the idea is proposed that there can be variation in the morphometric character of different breeds of Oryctolagus cuniculus but there are negligible scientific research base evidences for it. So in this study interbreed craniometric comparison of the European rabbit is carried out to trace out their intergender and intraspecific morphometric variations. The study material consists of 32 sexually mature rabbits belong to two breeds of European rabbit that are New Zealand rabbit (eight males and …

A Crowdsourced Gnss And Ppp Reference Network, Steve Malkos, Frank Van Diggelen

Defensive Publications Series

Due to its requirements for well-positioned base stations and lengthy times-to-first-fix, the Precise Point Positioning (PPP) techniques for decimeter positioning haven't found widespread application in navigation in smartphones. In principle, a global network of PPP base stations can provide decimeter-level accuracy to various positioning applications, including smartphone-based navigation. However, a global network of PPP base stations that can monitor and gather satellite information is expensive to build and maintain. This disclosure describes a crowdsourced, dense, PPP network and ephemeris-coverage map that can enable GNSS chipsets (e.g., utilized in smartphones and other mobile devices) to obtain decimeter-level positioning accuracy.

Resonant Band Engineering Of Ferroelectric Tunnel Junctions, Jing Su, Xingwen Zheng, Zheng Wen, Tao Li, Shijie Xie, Karin M. Rabe, Xiaohui Liu, Evgeny Y. Tsymbal

Department of Physics and Astronomy: Faculty Publications

We propose energy band engineering to enhance tunneling electroresistance (TER) in ferroelectric tunnel junctions (FTJs). We predict that an ultrathin dielectric layer with a smaller band gap, embedded into a ferroelectric barrier layer, acts as a switch controlling high- and low-conductance states of an FTJ depending on polarization orientation. Using first-principles modeling based on density functional theory, we investigate this phenomenon for a prototypical SrRuO₃/BaTiO₃/SrRuO₃ FTJ with a BaSnO₃ monolayer embedded in the BaTiO₃ barrier. We show that in such a composite-barrier FTJ, ferroelectric polarization of BaTiO₃ shifts the conduction-band minimum of …

Tracking The Amide I And Αcoo− Terminal Ν(C=O) Raman Bands In A Family Of L-Glutamic Acid-Containing Peptide Fragments: A Raman And Dft Study, Ashley E. Williams, Nathan I. Hammer, Ryan C. Fortenberry, Dana N. Reinemann

Faculty and Student Publications

The E-hook of β-tubulin plays instrumental roles in cytoskeletal regulation and function. The last six C-terminal residues of the βII isotype, a peptide of amino acid sequence EGEDEA, extend from the microtubule surface and have eluded characterization with classic X-ray crystallographic techniques. The band position of the characteristic amide I vibration of small peptide fragments is heavily dependent on the length of the peptide chain, the extent of intramolecular hydrogen bonding, and the overall polarity of the fragment. The dependence of the E residue’s amide I ν(C=O) and the αCOO− terminal ν(C=O) bands on the neighboring side chain, the length …

Archivesspace Adventures: A Migration, Adam Stephen Guy Smith, Heidi J. Southworth

Library Services Publications

On February 4, 2019, the University Archives and Southern Minnesota Historical Center at Minnesota State University, Mankato successfully launched a new archival tool for our patrons called ArchivesSpace. While this at first glance may not seem like a big deal, the journey that the archives undertook to transform this search tool from a set of static HTML pages (all 700+ of them) to an easy-to-use search engine contained danger around every corner. The team had to fend off lions, tigers, and bears and had to blaze a path through a thick forest of metadata and archival records. The journey traveled …

Accessing Improbable Foldamer Shapes With Strained Macrocycles., Ko Urushibara, Yann Ferrand, Zhiwei Liu, Kosuke Katagiri, Masatoshi Kawahata, Estelle Morvan, Ryan D'Elia, Vojislava Pophristic, Aya Tanatani, Ivan Huc

College of Science & Mathematics Departmental Research

The alkylation of some secondary amide functions with a dimethoxybenzyl (DMB) group in oligomers of 8-amino-2-quinolinecarboxylic acid destabilizes the otherwise favored helical conformations, and allows for cyclization to take place. A cyclic hexamer and a cyclic heptamer were produced in this manner. After DMB removal, X-ray crystallography and NMR show that the macrocycles adopt strained conformations that would be improbable in noncyclic species. The high helix folding propensity of the main chain is partly expressed in these conformations, but it remains frustrated by macrocyclization. Despite being homomeric, the macrocycles possess inequivalent monomer units. Experimental and computational studies highlight specific fluxional …

Highly Integrated And Miniaturized 3d Printed Serial Dilution Microfluidic Devices For Dose-Response Assays, Jose Luis Sanchez Noriega

Theses and Dissertations

The ability to generate a range of concentrations of various solutions rapidly and conveniently is an ongoing need in biotechnology. In this thesis we demonstrate how we took advantage of the full process control afforded by our recent custom high resolution 3D printer and resin advances to realize highly integrated and miniaturized microfluidic components for simultaneous on-chip serial dilution for dose-response assays. With judicious selection of mixed layer thicknesses and pixel-by-pixel dose control, we show that the diameter of 3D printed membrane valves can be reduced from 300 µm to 46 µm. We further introduce an entirely new kind of …

Cryptic Constituents: The Paradox Of High Flux–Low Concentration Components Of Aquatic Ecosystems, Malin Olofsson, Mary E. Power, David A. Stahl, Yvonne Vadeboncoeur, Michael T. Brett

Biological Sciences Faculty Publications

The interface between terrestrial ecosystems and inland waters is an important link in the global carbon cycle. However, the extent to which allochthonous organic matter entering freshwater systems plays a major role in microbial and higher-trophic-level processes is under debate. Human perturbations can alter fluxes of terrestrial carbon to aquatic environments in complex ways. The biomass and production of aquatic microbes are traditionally thought to be resource limited via stoichiometric constraints such as nutrient ratios or the carbon standing stock at a given timepoint. Low concentrations of a particular constituent, however, can be strong evidence of its importance in food …

Classifying Ingestive Behavior Of Dairy Cows Via Automatic Sound Recognition, Guoming Li, Yijie Xiong, Qian Du, Zhengxiang Shi, Richard S. Gates

Department of Animal Science: Faculty Publications

Determining ingestive behaviors of dairy cows is critical to evaluate their productivity and health status. The objectives of this research were to (1) develop the relationship between forage species/heights and sound characteristics of three different ingestive behaviors (bites, chews, and chew-bites); (2) comparatively evaluate three deep learning models and optimization strategies for classifying the three behaviors; and (3) examine the ability of deep learning modeling for classifying the three ingestive behaviors under various forage characteristics. The results show that the amplitude and duration of the bite, chew, and chew-bite sounds were mostly larger for tall forages (tall fescue and alfalfa) …

Kinetic Modeling Study Of Laminar Burning Velocity Of Gasoline–Ethanol–Methanol Blends At Elevated Temperature And Pressure, Ahmad Syihan Auzani, Cahyo Setyo Wibowo, Riesta Anggarani, Yulianto Sulistyo Nugroho, Bambang Sugiarto

Makara Journal of Technology

Gasoline–ethanol–methanol (GEM) blends have been considered to replace pure gasoline as spark ignition engine fuel. Their physical and chemical properties and performance and emission measurements from real engines have been reported previously. However, a fundamental study that can explain the unique results of GEM compared with those of pure gasoline is lacking. This study aims to compare the laminar burning velocity of GEM blends at different mixtures, equivalence ratios, temperatures, and pressures with that of pure gasoline. A laminar flame propagation model and reaction mechanisms from the literature were were for a numerical simulation. In this study, the chemical components …

Music Information Retrieval Based On Active Frequency, Hardianto Wibowo, Wildan Suharso, Yufis Azhar, Galih Wasis Wicaksono, Agus Eko Minarno, Dani Harmanto

Makara Journal of Technology

Music is the art of combining frequencies. A balance of frequencies gives rise to a harmonious tone. Several features of music can be analyzed, and they include sociocultural background, lyrics, mood, tempo, rhythm, harmony, melody, timbre, and instrumentation. In this study, we use the frequency of instrumentation as a feature for classification because each instrument has a frequency range. To test this frequency range, we use five music genres and one music playing skill. The five genres are dangdut, electronic dance music (EDM), metal, pop/rock, and reggae. The music playing skill is acoustic. Active frequencies are tested using the k-nearest …

Predictive Delivery Man Assignment Problem Using Deep Learning, Rahmadini Payla Juarsa, Taufik Djatna

Makara Journal of Technology

Dispatching is a critical part in current online shopping. It relates to how the delivery man assignment should minimize cost along with the service from a source to an end customer with an appropriate scheduled time. The problem arises as neither enough products to deliver nor delivery men are available for dispatch, resulting in suboptimal service and a waste of money. The study aimed to formulate the cost of restaurant dispatching for inducing a deep learning-based solution with the gated recurrent unit recurrent neural network to receive hourly order data and to engage the result for near feature delivery man …

Automatic Calibration For Ce-Qual-W2 Model Using Improved Global-Best Harmony Search Algorithm, Afshin Shabani, Xiaodong Zhang, Xuefeng Chu, Haochi Zheng

Faculty Publications

CE-QUAL-W2 is widely used for simulating hydrodynamics and water quality of the aquatic environments. Currently, the model calibration is mainly based on trial and error, and therefore it is subject to the knowledge and experience of users. The Particle Swarm Optimization (PSO) algorithm has been tested for automatic calibration of CE-QUAL-W2, but it has an issue of prematurely converging to a local optimum. In this study, we proposed an Improved Global-Best Harmony Search (IGHS) algorithm to automatically calibrate the CE-QUAL-W2 model to overcome these shortcomings. We tested the performance of the IGHS calibration method by simulating water temperature of Devils …

A Bibliometric Content Analysis Of Do-It-Yourself (Diy) Science: Where To From Here For Management Research?, Peter Galvin, Anton Klarin, Richard Nyuur, Nicholas Burton

Research outputs 2014 to 2021

Do-it-yourself (DIY) science research is currently in an expansion phase both in terms of its depth (with an increasing number of papers published each year) and its scope (with the core ideas being linked to an increasing number of constructs). To develop a more holistic appreciation of how the field has developed and to identify potential avenues of future research we undertake a bibliometric content analysis of the DIY science literature post 1980. We find four major clusters pertaining to education, culture, the operationalising of DIY science (including commercialisation) and technology-related issues. We review each of these clusters and the …
