Do Androids Dream of Bad News?

Breaking bad news is one of the toughest things to do in any field dealing with client care. As automation and technology increasingly interweave with human experience, there is growing concern about whether automated agents (‘‘AAs”) would be adequate to perform such a complex emotional act. In this paper, I draw from the literature in psychology and computer science to understand how individuals might react to automated agents (AAs) and address some of the strengths and limitations of AAs. I raise several legal and empirical issues that future designers and users of AAs must consider, including disclosure of and liability for an AA’s presence

When Whispers Enter the Cloud

With increased awareness of workplace harassment in recent years, the idea of enhanced reporting around sexual misconduct has gained traction. As a result, several technologies – from smartphone apps to well-publicized services – have been introduced with the goals of preventing, enabling reports of, and even predicting sexual misconduct at work, school and in public. But to what extent are these technologies secure and accessible to survivors? This Note documents the existing resources and proposes a framework focusing on privacy and participation for evaluating these tools intended to benefit survivors

Investigating the Construct of Topical Knowledge in a Scenario-Based Assessment Designed to Simulate Real-Life Second Language Use

The vast development of digital technology and the widespread use of social network platforms have reshaped how we live in the world. For L2 learners to maximally utilize their language proficiency to function effectively as members of modern society, they need not only the necessary L2 knowledge, skills, and abilities (KSAs) but also essential topical knowledge. While many researchers believe that topical knowledge should be viewed as an integral component of L2 communicative competence, the role of topical knowledge has not always been accounted for in an assessment context due to the difficulty of operationalizing the construct. Scenario-based assessment, an innovative, technology-based assessment approach, allows great affordances for expanding the measured constructs of an assessment. It is designed expressly for learners to demonstrate their KSAs in a context that simulates real-life language use. Through the utilization of a sequence of thematically-related tasks, along with simulated character interaction, scenario-based assessment offers opportunities to examine L2 learners’ communicative competence in a purposeful, interactive, and contextually meaningful manner. In this study, a scenario-based language assessment (SBLA) was developed to measure high-intermediate L2 learners’ topical knowledge and their L2 KSAs as part of the broadened construct of L2 communicative competence. To fulfill the scenario goal, learners were required to demonstrate their listening, reading, and writing abilities to build and share knowledge. In addition, learners’ prior topical knowledge was measured and their topical learning was tracked using the same set of topical knowledge items. A total of 118 adult EFL learners participated in the study. The results showed that the SBLA served as an appropriate measure of high-intermediate learners’ L2 proficiency. The topical knowledge items were found to function appropriately, supporting the use of the SBLA to measure topical knowledge as part of the broadened construct of communicative competence. In addition, most learners exhibited substantial topical learning over the course of the SBLA, suggesting that with proper contextualization, learning can be facilitated within an assessment. In sum, this study demonstrated the potential value of scenario-based assessment as an approach to measure complex constructs of communicative language competence in L2 context

Sediment deposition within and around a finite patch of model vegetation over a range of channel velocity

The interaction between flow and vegetation creates feedbacks to deposition that vary with channel velocity. This experimental study describes how channel velocity and stem-generated turbulence influence the deposition within and around an emergent patch of model vegetation, with a particular focus on deposition within the patch. The Reynolds number threshold for stem-scale turbulence generation was determined using velocity spectra and flow visualization. At high channel velocity resuspension occurred in the bare regions of the channel and a nonuniform spatial distribution of net deposition was observed around and within the patch. In contrast, at low channel velocity there was no (or limited) resuspension and a uniform distribution of net deposition was observed around and within the patch. The deposition inside the patch was enhanced, relative to a bare-channel control, only when the following two criteria were met: (1) the absence of stem turbulence, and (2) the presence of sediment resuspension in the bare channel. Comparison to previous lab and field studies further support these criteria.National Science Foundation (U.S.) (Grant EAR-1414499

The Application of Natural Language Processing and Automated Scoring in Second Language Assessment

Natural language processing (NLP) is an area of research that is used to investigate the application of natural language and is the foundation of machine translation, natural language text processing, natural language generation, multilingual and cross language information retrieval, speech recognition, parsing, and expert systems. To understand natural language in order to build or select appropriate algorithms for processing, three major issues are called into attention: humans’ thought processes, the meaning of linguistic input in context, and world knowledge. These considerations have led to the development of various types of NLP tools for lexical and morphological analysis, semantic and discourse analysis, as well as knowledge-based approaches (c.f., Chowdhury, 2003). After decades of evolution and advancement, the current stage of NLP, as Xi (2010) pointed out, has allowed language testing researchers to apply its techniques in developing automated scoring systems for the purpose of language learning and assessment

The Conceptualization and Operationalization of Diagnostic Testing in Second and Foreign Language Assessment

Diagnostic testing has long been valued by language testing researchers and practitioners for its ability to inform both teaching and learning. However, the number of well-developed diagnostic language tests is relatively low, most likely due to the difficulty in constructing a diagnostic test that incorporates a wide enough range of language skills. In recent years, the advancement of technologies has allowed for the development of several large-scale, computer-based diagnostic language tests, as well as more sophisticated measurement methods to conduct diagnosis. This article first provides the theoretical ground for how diagnosis has been conceptualized in language testing over the past 60 years. Then, several current approaches to operationalizing diagnosis in second and foreign language assessment, including both tests and methods, are reviewed. The article concludes with reflections on diagnostic testing in second and foreign language assessment at its current state, as well as recommendations for its future directions

Concerns and Structural Barriers Associated with WIC Participation among WIC-eligible Women

Objectives: To examine sociodemographic, psychosocial concerns, and structural barriers associated with women\u27s participation in the USDA\u27s Women, Infants, and Children (WIC) program among those eligible for the program. Design and Sample: 1,634 White, African American, Hispanic, and Asian/Pacific Islander (A/Pl) women from the New York City area completed the Pregnancy Risk Assessment Monitoring System (PRAMS) from 2004-2007, a population-based survey. Measurements: Data on WIC eligibility and participation, sociodemographic details, unintended pregnancy, social support, and structural barriers were evaluated. Results: Hispanics and Blacks were 4.1 and 2.4 times more likely to participate, respectively, in the WIC program relative to Whites. Mothers reporting unplanned pregnancies, fewer social supports, and more structural barriers (e.g., transportation) were less likely to participate in WIC. Race-stratified analyses revealed race/ethnic differences in the pattern of barriers; unintended pregnancy and structural problems were barriers associated with WIC participation particularly for A/Pl. Conclusions: WIC-eligible women with unintended pregnancies and fewer social supports tend to participate in WIC, but those who experience more structural barriers are less likely to participate. A/Pl women may face specific challenges to WIC participation. Careful attention is needed to understand the unique attitudes and behaviors in the process of participating in WIC

Rings and Radial Waves in the Disk of the Milky Way

We show that in the anticenter region, between Galactic longitudes of $110^\circ<l<229^\circ$, there is an oscillating asymmetry in the main sequence star counts on either side of the Galactic plane using data from the Sloan Digital Sky Survey. This asymmetry oscillates from more stars in the north at distances of about 2 kpc from the Sun to more stars in the south at 4-6 kpc from the Sun to more stars in the north at distances of 8-10 kpc from the Sun. We also see evidence that there are more stars in the south at distances of 12-16 kpc from the Sun. The three more distant asymmetries form roughly concentric rings around the Galactic center, opening in the direction of the Milky Way's spiral arms. The northern ring, 9 kpc from the Sun, is easily identified with the previously discovered Monoceros Ring. Parts of the southern ring at 14 kpc from the Sun (which we call the TriAnd Ring) have previously been identified as related to the Monoceros Ring and others have been called the Triangulum Andromeda Overdensity. The two nearer oscillations are approximated by a toy model in which the disk plane is offset by of the order 100 pc up and then down at different radii. We also show that the disk is not azimuthally symmetric around the Galactic anticenter and that there could be a correspondence between our observed oscillations and the spiral structure of the Galaxy. Our observations suggest that the TriAnd and Monoceros Rings (which extend to at least 25 kpc from the Galactic center) are primarily the result of disk oscillations.Comment: 19figures, 2tables, ApJ accepte
