openalexR: An R-Tool for Collecting Bibliometric Data from OpenAlex
Bibliographic databases are indispensable sources of information on published literature. OpenAlex is an open-source collection of academic metadata that enable comprehensive bibliographic analyses (Priem et al. 2022). In this paper, we provide details on the implementation of openalexR, an R package to interface with the OpenAlex API. We present a general overview of its main functions and several detailed examples of its use. Following best API package practices, openalexR offers an intuitive interface for collecting information on different entities, including works, authors, institutions, sources, and concepts. openalexR exposes to the user different API parameters including filtering, searching, sorting, and grouping. This new open-source package is well-documented and available on CRAN

Modulations of interfacial magnetic properties using structurally inverted magnetic tri-layer systems: Toward skyrmion formation
Various magnetic properties such as the interfacial Dzyaloshinskii-Moriya interaction (DMI) and the perpendicular magnetic anisotropy (PMA) in structurally inverted Pd/Co/Pt and Pt/Co/Pd tri-layer stacks are systematically investigated by performing an inelastic light scattering method. Two examined individual multilayer structures are identical, but the stacking order is inverted for each other. Here, we demonstrate that the interfacial DMI energy densities and the saturation magnetization values for both systems are almost similar. However, the surface magnetic anisotropy energy densities of Pd/Co/Pt systems are dramatically decreased up to 34% compared with Pt/Co/Pd system, while the interfacial DMI is kept. Since a large interfacial DMI and a small PMA (or domain wall energy) are required to form magnetic skyrmion phases, the Pd/Co/Pt system can be one of the promising candidates. According to the thickness dependent measurements, we show a possibility of the existence of skyrmion phases in the Pd/Co/Pt system within a certain range of Co layer thickness at room temperature without external magnetic fields. © 2021 Author(s).1
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
The precautionary demand for commodity stocks
This paper develops a theory of the precautionary demand for commodity stocks. It suggests that commodity stocks are held for precautionary purposes by producers, consumers, and intermediate processors, while speculators hold stocks on the expectation of capital gains from a subsequent price rise. Producer and consumer stocks usually account for the largest share of commercial stocks held at any point in time. For example, at the end of 1990, stocks held by producers and consumers of copper were 72 percent of all commercial stocks of the market economy countries. Yet, the theory explaining the behavior of this class of stocks has not progressed much beyond the concept of convenience yield, first introduced by Kaldor (1939). This paper proposes an alternative theory. Holding of stocks by producers and consumers is viewed as precautionary behavior towards output and price risks. As a theory of behavior towards risks, the precautionary stock demand model encompasses speculative demand by both producers and consumers. Furthermore, both stocks and futures are treated as precautionary instruments, in contrast to the dichotomy that only stocks provide convenience yield while futures are hedging instruments.Access to Markets,Markets and Market Access,Economic Theory&Research,Environmental Economics&Policies,Non Bank Financial Institutions
