It indirectly encourages the growth of the social activities online. Even though COVID- 19 is no longer a big threat to the world, people already used to rely on the Internet for …

The Impact Of Fdi And Financial Depth On Eu Regional Growth: Income And Spatial Heterogeneity, Marialena Petrakou, Randolph Luca Bruno, Nick Phelps

Economic and Business Review

Background and objective: The paper explores the impact of foreign direct investment and financial development on regional growth at the EU regional level for 2005–2017. Both FDI and financial development are important determinants of the regions’ growth, but not for all EU regions homogeneously. Some EU regions seem to benefit more than others, depending on certain characteristics, which implies that FDI attraction policies need to bear in mind not only country specificities, but also regional specificities, hence confirming the need for developing FDI attraction policies at the subnational level: financial development, capacity building, and Investment Promotion Agencies are key, …

Conceptual Development: How Do Early Educators And Teachers Support Children's Early Thinking In Stem?, Marilyn Fleer

2021-2030 ACER Research Conferences

As national and state-based reforms in early education roll-out across Australia, concern for building a well-qualified workforce to meet growing demand has intensified. In parallel with the reforms, teachers and educators are reminded by the recently released 2022 Early Years Learning Framework to design programs that support intentionality in play-based learning. However, the literature shows that despite the concept of intentional teaching being around since 2009, difficulties with how to do this remains. This presentation takes up this challenge, by 1) sharing the collective findings of 6 Australian Research Council-funded research projects into play and learning in STEM; and 2) …

Limoniic Acid Is A Sex Attractant Pheromone Component Of Limonius Agonus (Coleoptera: Elateridae), Wim Van Herk, Regine Gries, Jocelyn Smith, Ian Scott, Gerhard Gries

The Great Lakes Entomologist

Recently, (E)-4-ethyloct-4-enoic acid (limoniic acid) has been reported as the major sex attractant pheromone component of L. canus and L. californicus (Coleoptera: Elateridae) in western North America. Our objective was to determine whether limoniic acid is also a sex attractant pheromone component of the eastern field wireworm, Limonius agonus (Say). In gas chromatographic-electroantennographic detection (GC-EAD) analyses of headspace volatiles from L. agonus females, antennae from male L. agonus responded to limoniic acid as a trace component. In field experiments, traps baited with synthetic limoniic acid, or its analog (E)-5-ethyloct-4-enoic acid, afforded captures of male L. …

Temporal Changes In Temperature May Suggest Microhabitat Shifts In Larval Spongillafly Climacia Areolaris Hagen (Neuroptera: Sisyridae) Abundance And Density In A Temperate Freshwater Lake, John R. Wallace, M. Eric Benbow, Cindy Willman-Kinsey

The Great Lakes Entomologist

Abiotic factors such as temperature and depth are known to affect aquatic insect populations and are thought to be major variables that directly impact how communities are assembled and populations distributed. The purpose of this study was to examine the role of temperature and depth in structuring C. areolaris populations within a temperate freshwater quarry. Larval densities among individual sponges at different depths were determined over six months in a Pennsylvania quarry. Sponges from four depths (7.0 - 8.0 m; 8.1 - 9.0 m; 9.1 - 10.0 m and 10.1 - 12.0) were collected once per month (n = 3) …

Does Play Belong In The Primary School Classroom?, Bo Stjerne Thomsen, Rachel Parker

2021-2030 ACER Research Conferences

Learning through play has emerged as an important strategy to promote student engagement, inclusion, and holistic skills development beyond the preschool years.

Early Response To False Claims In Wikipedia, 15 Years Later, P.D. Magnus

Philosophy Faculty Scholarship

Fifteen years ago, I conducted a small study testing the error-correction tendency of Wikipedia. Not only is Wikipedia different now than it was then, the community that maintains it is different. Despite the crudity of that study’s methods, it is natural to wonder what the result would be now. So I repeated the earlier study and found surprisingly similar results.

Comparing Time Allocation For Teaching Science As Inquiry In Two Educator Preparation Science Methods Courses, Lori A. Dira

Faculty Journal Articles

How much time an institution allocates to content can indicate its overall importance and intended value to the educator preparation program. For decades there have been calls to integrate more authentic science inquiry experiences into not only undergraduate elementary science courses, but into all elementary educator preparation courses. Many elementary educators do not receive training on effective methods for teaching science, they will not feel comfortable and will likely have low self-efficacy. This study investigated the amount of time allocated to teaching science as inquiry and the knowledge participants had prior to and after taking an elementary teaching science methods …

Kv12-Encoded K+ Channels Drive The Day-Night Switch In The Repetitive Firing Rates Of Scn Neurons, Tracey O Hermanstyne, Nien-Du Yang, Daniel Granados-Fuentes, Xiaofan Li, Rebecca L Mellor, Timothy Jegla, Erik D Herzog, Jeanne M Nerbonne

2020-Current year OA Pubs

Considerable evidence suggests that day-night rhythms in the functional expression of subthreshold potassium (K+) channels regulate daily oscillations in the spontaneous firing rates of neurons in the suprachiasmatic nucleus (SCN), the master circadian pacemaker in mammals. The K+ conductance(s) driving these daily rhythms in the repetitive firing rates of SCN neurons, however, have not been identified. To test the hypothesis that subthreshold Kv12.1/Kv12.2-encoded K+ channels play a role, we obtained current-clamp recordings from SCN neurons in slices prepared from adult mice harboring targeted disruptions in the Kcnh8 (Kv12.1-/-) or Kcnh3 (Kv12.2-/-) locus. We found that mean nighttime repetitive firing rates …

Determinants Of Ifgf13-Mediated Regulation Of Myocardial Voltage-Gated Sodium (Nav) Channels In Mouse, Adrien Lesage, Maxime Lorenzini, Sophie Burel, Marine Sarlandie, Floriane Bibault, Cecilia Lindskog, Daniel Maloney, Jonathan R Silva, R Reid Townsend, Jeanne M Nerbonne, Céline Marionneau

2020-Current year OA Pubs

Posttranslational regulation of cardiac NaV1.5 channels is critical in modulating channel expression and function, yet their regulation by phosphorylation of accessory proteins has gone largely unexplored. Using phosphoproteomic analysis of NaV channel complexes from adult mouse left ventricles, we identified nine phosphorylation sites on intracellular fibroblast growth factor 13 (iFGF13). To explore the potential roles of these phosphosites in regulating cardiac NaV currents, we abolished expression of iFGF13 in neonatal and adult mouse ventricular myocytes and rescued it with wild-type (WT), phosphosilent, or phosphomimetic iFGF13-VY. While the increased rate of closed-state inactivation of NaV channels induced by Fgf13 knockout in …

A Grand Canonical Monte Carlo Simulation For The Evaluation Of Pore Size Distribution Of Nuclear-Grade Graphite From Kr Adsorption Isotherms, Giuliano M. Laudone, Katie L. Jones

School of Geography, Earth and Environmental Sciences

Characterizing materials with low surface areas or with very small sample sizes requires innovative approaches beyond traditional N2 and Ar adsorption measurements. The measurement of Kr adsorption isotherms is often employed to serve this purpose, yet its potential remains limited by the lack of models for the interpretation of the experimental results in terms of pore size distribution. In this work, simulated adsorption isotherms of Kr onto graphite in slit-shaped pores are generated with a Grand Canonical Monte Carlo method. The pore size distributions of nuclear-grade graphite samples and activated carbon are modelled by fitting simulated isotherms to the experimental …

On A Central Problem Of The Human Placenta Project, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Working Papers

This brief technical note describes a design concept for a low-cost, painless, noninvasive monitor of total placental blood flow during the third trimester of pregnancy. The approach may offer an overlooked solution to a central problem of the human placenta project. A systems level biophysical analysis shows that jets of blood flow emerging from spiral arteries in the placenta generate characteristic 1/f or “pink noise” which is routinely audible, but typically ignored, during fetal phonocardiography. The amplitude of the 1/f noise, recorded at a standardized location in an individual patient, is a measure of total placental blood flow that is …

Large And Tunable Magnetoresistance In Van Der Waals Ferromagnet/Semiconductor Junctions, Wenkai Zhu, Yingmei Zhu, Tong Zhou, Xianpeng Zhang, Hailong Lin, Qirui Cui, Faguang Yan, Ziao Wang, Yongcheng Deng, Hongxin Yang, Lixia Zhao, Igor Žutić, Kirill D. Belashchenko, Kaiyou Wang

Department of Physics and Astronomy: Faculty Publications

Magnetic tunnel junctions (MTJs) with conventional bulk ferromagnets separated by a nonmagnetic insulating layer are key building blocks in spintronics for magnetic sensors and memory. A radically different approach of using atomically-thin van der Waals (vdW) materials in MTJs is expected to boost their figure of merit, the tunneling magnetoresistance (TMR), while relaxing the lattice-matching requirements from the epitaxial growth and supporting high-quality integration of dissimilar materials with atomically-sharp interfaces. We report TMR up to 192% at 10 K in all-vdW Fe₃GeTe₂/GaSe/Fe₃GeTe₂ MTJs. Remarkably, instead of the usual insulating spacer, this large TMR …

The thermodynamics of model host–guest-binding reactions is examined in depth using isothermal titration calorimetry. In conflict with classical thermodynamics, the results indicate that the equilibrium-binding quotient, K, is not a constant for all pairings. This outcome is predicted by an equation for binding equilibria that includes an explicit term for the change in solvation free energy that accompanies the formation of a binary complex. Application of this framework to the experimentally observed concentration dependence of K allows one to obtain the energetic contribution of the solvent, a linked equilibrium denoted here as ΔGH2O. The estimated values of ΔGH2O are large …

The Wealth Of Our Commonwealth: Money, Capital, And Finance In A Productive Commercial Republic, Robert Hockett

The Business, Entrepreneurship & Tax Law Review

There is a share of the investment capital available in any society that is generated by the public. In contemporary societies with well-developed payment systems and effective public governance, this share tends to grow large in comparison to that originated by non-public sources, the latter is intermediated and thus must be pre-accumulated, while the former is generated and is the source of what is accumulated. In spite of these truths, the US outsources management of its public capital stock to private sector financial institutions. This is a practice that a host of underappreciated collective action predicaments endemic to decentralized market …

Many-Valued Coalgebraic Logic: From Boolean Algebras To Primal Varieties, Alexander Kurz, Wolfgang Poiger

Engineering Faculty Articles and Research

We study many-valued coalgebraic logics with primal algebras of truth-degrees. We describe a way to lift algebraic semantics of classical coalgebraic logics, given by an endofunctor on the variety of Boolean algebras, to this many-valued setting, and we show that many important properties of the original logic are inherited by its lifting. Then, we deal with the problem of obtaining a concrete axiomatic presentation of the variety of algebras for this lifted logic, given that we know one for the original one. We solve this problem for a class of presentations which behaves well with respect to a lattice structure …
