The use of educational testing in the United States has been criticized for its inequitable effects on different populations of students. Many assume that new forms of assessment will lead to more equitable outcomes. Linda Darling-Hammond argues in this article, however, that alternative assessment methods, such as performance-based assessment, are not inherently equitable, and that educators must pay careful attention to the ways that the assessments are used. Some school reform strategies, for example, use assessment reform as a lever for external control of schools. These strategies, Darling-Hammond argues, are unlikely to be successful and the assessments are unlikely to be equitable because they stem from a distrust of teachers and fail to involve teachers in the reform processes. Darling-Hammond argues instead for policies that ensure "top-down support for bottom-up reform," where assessment is used to give teachers practical information on student learning and to provide opportunities for school communities to engage in "a recursive process of self-reflection, self-critique, self-correction, and self-renewal." Ultimately, then, the equitable use of performance assessments depends not only on the design of the assessments themselves, but also on how well the assessment practices are interwoven with the goals of authentic school reform and effective teaching.

English language learning (ELL) children suspected of having specific-language impairment (SLI) should be assessed using the same methods as monolingual English-speaking children born and raised in the United States. In an effort to reduce over- and under-identification of ELL children as SLI, speech-language pathologists (SLP) must employ nonbiased assessment practices. This article presents several evidence-based, nonstandarized assessment practices SLPs can implement in place of standardized tools. As the number of ELL children SLPs come in contact with increases, the need for well-trained and knowledgeable SLPs grows. The goal of the authors is to present several well-establish, evidence-based assessment methods for assessing ELL children suspected of SLI.

In the United States, the COVID-19 pandemic has decreased partnered sexual behavior and increased the use of enhancement (e.g., toys). This has been partly attributed to reduced social interactions and stress. However, individuals’ perceptions of changes are missing in research. This study aims to examine how adults perceive changes in their sexuality during the pandemic. We conducted a nationwide survey of US adults from April–June 2020 (N = 326). This qualitative study examines the open-ended responses using thematic analyses. The following themes emerged from the data: (1) changes in the purpose of sex; (2) changes in sexual identity; (3) decreases in sex drive and desire; (4) increases in sex drive and desire; (5) fluctuations in sex drive and desire; (6) increased sexual experimentation and reflection. The stress, changes in home responsibilities and living situations, and time spent with partners (more or less) has affected individuals by increasing or decreasing their sex drive and desire. Participants responded to changes with self-reflection and awareness, and incorporating new practices (e.g., technology, kink). The purpose of sex has shifted in order to gain intimacy or connect, or to pass time. These changes were perceived as both positive and negative, and more research is needed to determine the durability of these changes.

AbstractThe regulatory standards of the United States Food and Drug Administration (FDA) require substantial evidence of effectiveness from adequate and well-controlled trials that typically use a valid comparison to an internal concurrent control. However, when it is not feasible or ethical to use an internal control, particularly in rare disease populations, relying on external controls may be acceptable. To better understand the use of external controls to support product development and approval, we reviewed FDA regulatory approval decisions between 2000 and 2019 for drug and biologic products to identify pivotal studies that leveraged external controls, with a focus on select therapeutic areas. Forty-five approvals were identified where FDA accepted external control data in their benefit/risk assessment; they did so for many reasons including the rare nature of the disease, ethical concerns regarding use of a placebo or no-treatment arm, the seriousness of the condition, and the high unmet medical need. Retrospective natural history data, including retrospective reviews of patient records, was the most common source of external control (44%). Other types of external control were baseline control (33%); published data (11%); and data from a previous clinical study (11%). To gain further insights, a comprehensive evaluation of selected approvals utilizing different types of external control is provided to highlight the variety of approaches used by sponsors and the challenges encountered in supporting product development and FDA decision making; particularly, the value and use of retrospective natural history in the development of products for rare diseases. Education on the use of external controls based on FDA regulatory precedent will allow for continued use and broader application of innovative approaches to clinical trial design, while avoiding delays in product development for rare diseases. Learnings from this review also highlight the need to update regulatory guidance to acknowledge the utility of external controls, particularly retrospective natural history data.

This paper reports on a pilot study that was conducted during a technical trial of a new ePortfolio system at a large Australian university. Students from a large (n = 325) first-year educational technology course were given the opportunity to use the new ePortfolio system weekly as part of their reflective practice at the end of the hands-on tutorial classes and also through a blogging assignment that required six posts throughout the semester. Although the students reflecting on their work and ePortfolios themselves are not new concepts, this paper reports how assessment practices can be improved using ePortfolios and how students can improve their reflective practice through simple and regular use throughout the 12-week semester that the study was conducted. From the class, 208 students responded to the survey with the results being positive. The students were able to use the system easily and did not report many problems with crashing or freezing. The lessons learnt form an important part of this study for future iterations with these reported in the paper.

Abstract Fall armyworm (FAW), Spodoptera frugiperda (Smith, 1797), is a polyphagous, voracious, and economically important agricultural pest. Biological control of FAW is a strategy that must be further explored. This study evaluated six baculovirus strains isolated from infected FAW larvae from Mexico, Argentina, Honduras, and the United States. Five alphabaculoviruses (SfNPV-An2, SfNPV-Arg, SfNPV-Fx, SfNPV-Ho and SfNPV-Sin) and one betabaculovirus (SfGV-RV), were tested against FAW larvae, showing a wide diversity of virulence levels among strains when their estimated LC50s were compared, being SfNPVArg, SfNPV-Ho and SfNPV-Fx more virulent than SfNPV-An 2 , SfNPV-Sin and SfGV-RV. To determine any virulence difference in vitro studies of these isolates, Sf9 cell cultures were used. Interestingly, only ODVs from four of the test SfNPV strains showed infectivity on Sf9 cell cultures, and some differences in virulence were observed. Genomic restriction analyses and partial sequences of lef-8, lef-9 , and polh/granulin genes showed little variability among alphabaculoviruses, both, among them and with previously reported sequences. However, sequences from SfGV-RV were closer to previously reported sequences from the SfGVVG008 strain than the SfGV-Arg and SfGV-VG014 strains. The great difference in the in vivo virulence was not correlated with great similarity among the isolates. The characterization of these six baculoviruses isolates offers the basis for exploring their potential as biological control agents against S. frugiperda, as well the initial studies on their specific infection mechanisms, evolution, and ecology.

By the standards of prosperity and peace, the post–Cold War international order has been an unparalleled success. Over the last thirty years, there has been more creation of wealth and a greater reduction of poverty, disease, and food insecurity than in all of previous history. During the same period, the numbers and lethality of wars have decreased. These facts have not deterred an alternative assessment that civil violence, terrorism, failed states, and numbers of refugees are at unprecedentedly high levels. But there is no global crisis of failed states and endemic civil war, no global crisis of refugees and migration, and no global crisis of disorder. Instead, what we have seen is a particular historical crisis unfold in the greater Middle East, which has collapsed order within that region and has fed the biggest threat to international order: populism in the United States and Europe.

In this study we propose a taxonomy for assessment in mathematics, which we call the assessment component taxonomy, to identify those components of mathematics that can be successfully assessed using alternative assessment formats. Based on the literature on assessment models and taxonomies in mathematics, this taxonomy consists of seven mathematics assessment components, hierarchically ordered by cognitive level, as well as the nature of the mathematical tasks associated with each component. Using a model that we developed earlier for measuring the quality of mathematics test items, we investigate which of the assessment components can be successfully assessed in the provided response question (PRQ) format, in particular multiple choice questions (MCQs), and which can be better assessed in the constructed response question (CRQ) format. The results of this study show that MCQs can be constructed to evaluate higher order levels of thinking and learning. The conclusion is that MCQs can be successfully used as an assessment format in undergraduate mathematics, more so in some assessment components than in others. The inclusion of the PRQ assessment format in all seven assessment components can reduce the large marking loads, associated with continuous assessment practices in undergraduate mathematics, without compromising the validity of the assessment.
