Metal Antagonists and Metals

Abstract: The side effects of drugs annuals forms a series of volumes in which the adverse effects of drugs and adverse reactions to them are surveyed. The series supplements the contents of Meyler's Side Effects of Drugs: The International Encyclopedia of Adverse Drug Reactions (ADRs) and Interactions. This review of the January 2017–December 2017 publications on metal antagonists and selected metals includes ammonium tetrathiomolybdate, deferasirox, deferiprone, deferoxamine/desferrioxamine, dimercaptopropanesulfonic acid, edetic acid, hydroxyurea, d -Penicillamine, polystyrene sulphonates, tiopronin, and the selected metals cadmium, cobalt, titanium, vanadium, and zinc.

Help Wanted: Presidential Prioritization of Appointments

Abstract: Though there is extensive scholarly description of the incentives, constraints, and appointment choices made by new administrations, as well as the ritual scoring of how newly-inaugurated presidents fare in matching the appointment rates of previous, we still know little about how presidents systematically choose which positions get filled first. Because of three main challenges--the scale and complexity of the executive branch compared to the presidential campaign and advisory staff , principal-agent problems, and time constraints--presidents cannot easily ll every position. They have to identify the priority positions in each agency on which they will focus at the start of the administration. This paper outlines how a combination of presidential electoral motivation and an emphasis on management teams rather than individual appointments explains why and how presidents prioritize appointments within agencies. Analyzing a new dataset of appointee entry and exit dates from three cabinet departments in the first terms of presidents George W. Bush and Barack Obama, I find that presidents prioritize the secretary's immediate management team and the offices for public affairs and congressional relations. The paper draws out implications of the findings for our understanding of appointment politics and the presidency more generally.

WHILE loops and the analogy of the single stroke engine

Abstract: Researchers have found that loop constructs, such as the WHILE (top tested) and REPEAT-UNTIL (bottom tested) in modern programming languages are problematic for a significant number of novice programming students[5]. In theory, any bottom tested loop can be implemented as a top tested loop. Unfortunately, the converse of this is not true, leading to some of the confusions experienced by beginners. To circumvent this and other problems, Taylor[7] advocates postponing the introduction of the REPEAT-UNTIL. Instead, he discriminates between two fundamental types of WHILE loops, designated the SENTINEL WHILE and the COUNTER WHILE, which are sufficient for the implementation of any loop. A key element of Taylor's pedagogical approach is the introduction of these concepts in the context of analogies. This approach is utilized in the exposition that follows.

Multibranch Regenerative DF Wireless Relay Networks under Channel Uncertainty and Node Geometry

Abstract: This paper studies channel uncertainty and node geometry influences on a regenerative distributed decode-and-forward (DF) wireless relay network. A network consisting of one-source-one-destination pair and N-multibranch relay nodes without a direct link between the source and the destination is investigated. A new proposed detection scheme employs the maximum ratio combiner (MRC) principle. The new detection scheme is applied at both relay nodes and the destination node, to optimally detect the original transmitted message from the source node. Monte-Carlo simulations were used to evaluate the bit error rate (BER) performance for the regenerative distributed DF wireless relay network using the new proposed MRC scheme.

Work in progress — Assessing information literacy in civil engineering

Abstract: Although information literacy is not specifically mentioned in the ABET outcomes, the development of these skills is essential to the achievement of several outcomes. Civil Engineering faculty at the United States Coast Guard Academy (USCGA) have developed performance indicators and assessment tools under existing ABET outcomes designed to develop and improve student information literacy skills. The link to ABET specific outcomes enables students to see the connection between information literacy and their ability to engage in lifelong learning, to follow contemporary issues, and to use modern information technology tools in their engineering work. The authors discuss steps taken at the USCGA to evaluate aspects of information literacy within the current assessment process in the Department of Civil Engineering.
