Growth Conditions for Zinc Crystals

Previous work by Schilling1 showed that additions of Cadmium were necessary to produce conditions favorable to growth of single crystals. The present work has to do with the effect of other impurities on growth conditions. At present it has been found, by using zinc with somewhat less iron impurity than Schilling\u27s zinc but with the same addition of Cadmium, that the region favorable to growth is more like the original one of Hoyem and Tyndall and considerably different from Schilling\u27s region

A 60- Year Record of the Demotechnic Index of States, 1960-2019

A country’s dependency on energy resources can be interpreted through the calculation of energy indices. The Demotechnic Index (DI) was used to determine the trajectory of energy efficiency of each state in the United States over the period 1960-2019. The DI serves as a measure of the energy intensity of states and a proxy for energy sustainability of each state.The DI is the ratio of total energy use to total metabolic energy demand of a population. Mathematically, DI = (E_T-E_M)/E_M E_T represents the total energy used (metabolic energy + technological energy in kilojoules annually, kJ/y), while EM represents the basic metabolic energy required by the population. Therefore, DI is the scalar multiple of energy used by a state over the quantity of energy required for simple human survival. The observed mean and median DI of the states increases somewhat irregularly during the period 1960-2019, ranging from means of 133.49 in 1960 to peak mean DI of 199.89 in the year 2000 and ending at mean of 173.45 in 2019, and medians of 75.58 in 1960 to 98.24 in 2019. Long-term incremental increase in energy intensity is a predictable outcome for a nation with ever-increasing population and increasing technological energy demand. Simply put, in a technological society, growing populations require greater energy consumption. (i.e. more people use more energy). Individual state DIs range across 4 orders of magnitude. New York had the highest calculated DI with a value of 2,127.03 in 1973. In 2016, Vermont had the lowest calculated DI at 4.69. Despite the broadly ranging DI scale, state-level DI values over 60-years fall into 3 broad categories illustrating long-term energy-use trajectories: increasing DI over time, stable DI over time, and decreasing DI over time. Few states change their energy trajectory during the period of observation. Incorporation of significant proportions of renewable energy sources in the state energy portfolios contributes to energy sustainability. However, energy sustainability is compromised if total energy use increases faster than population. Under such a scenario, energy intensity (i.e., DI) increases and requires additional energy production infrastructure and capacity, including additional renewable energy production capacity. Ideally, to progress toward energy sustainability, states must combine increased proportions of renewable energy sources with improved energy efficiency (i.e, reduced DI). Tracking DI trajectories over more than a half-century permits some long-term assessment of the energy efficiency of each state and, hence, an assessment of the relative commitment to energy-sustainability of state populations. The DI appeared to be responsive to a broad range of economic events that impact energy use. As such, DI appears to be meaningful as an index of energy intensity, energy efficiency, and aspects of energy sustainability. The strengths of the DI are its ease of calculation and evident scalability. It should be more widely adopted as an energy index

Pay-for-Performance Systems in State Government: Perceptions of State Agency Personnel Managers*

Pay for performance has been a widely used method of compensation in the public sector since the early 1980s, but a growing body of research has indicated that numerous problems can be associated with the application of performance-based compensation systems In late 1993, the federal government, after years of difficulty experienced with its merit pay program, took a significant step back from pay for performance through passage of the Performance Management and Recognition System Termination Act This research seeks to determine whether state governments are becoming similarly disenchanted with pay for performance To gain insight into this question, a survey was administered to a nationwide random sample of state agency personnel management executives Results indicate that pay for performance remains as popular as ever in state government, and that nearly all of the systems in the states utilize merit pay despite difficulties often associated with that approach to pay for performance.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Development and Simulation Testing of a Computerized Adaptive Measure of Communicative Functioning in Aphasia

Computerized adaptive testing (CAT), based on the mathematical framework of item response theory (IRT), has increasingly been implemented in patient reported outcome measures over the past decade (Fries, Bruce, & Cella, 2005). Given a calibrated item pool fit by an appropriate IRT measurement model, a CAT can produce reliable ability estimates more efficiently than traditional paper-and-pencil tests by administering items that are most informative given the examinee’s estimated ability level (Wainer, 2000). As conventional measures employed in the measurement of aphasia were developed under traditional measurement theory, many of these measures are long and inefficient, and are consequently unsuitable for regular clinical care. In addition, these conventional measures often fail to meet the needs of many community-dwelling stroke survivors whose impairments falls outside the range reliably measured by these tests (Doyle et al. 2012). IRT-based and in particular CAT patient reported outcome measures offer the possibility of substantial improvements in measurement technology for persons with aphasia

“Dubbing It Into the Earth”: A Conversation with Kaie Kellough

Faith Paré speaks with Kaie Kellough in the fall of 2020. What begins as a short Q&A on sound and its influences on his practice expands into a map of the sonic, poetic, and generational traces in his work that criss-cross between the Caribbean, Quebec, the Prairies, and West Africa. Paré and Kellough discuss their shared journeys, twenty years apart, of moving to Montreal to become poets, and what it means to wade in three lineages: Guyanese, Afro-diasporic, and Canadian

Development and simulation testing of a computerized adaptive version of the Philadelphia Naming Test

Impairment of naming ability is ubiquitous in aphasia and assessment of naming is central to clinical assessment (Nickels, 2002). One prominent naming test is the Philadelphia Naming Test (PNT) (Roach et al., 1996), which has favorable psychometric properties and has been used in many investigations of the theoretical nature of aphasic naming deficits (e.g., Dell et al., 1997; Schwartz et al, 2006). However, the PNT is a long test, limiting its usefulness in clinical settings. Recently, Walker & Schwartz (2012) published two 30-item PNT short forms (PNT30-A, PNT30-B) along with data supporting their reliability and validity. These short forms were developed using classical test theory methods, with attention to items’ lexical characteristics, their overall difficulty, and error type distributions
