Dan McGinn, Ben Kelcey, Heather Hill, and Mark Chin. Working Paper. Using Item Response Theory to Learn about Observational Instruments.Abstract

As many states are slated to soon use scores derived from classroom observation instruments in high-stakes decisions, developers must cultivate methods for improving the functioning of these instruments. We show how multidimensional, multilevel item response theory models can yield information critical for improving the performance of observational instruments.

Working Paper. “Virtual Watercoolers: A Field Experiment on Virtual Synchronous Interactions and Performance of Organizational Newcomers.” SSRN, Harvard Business School Technology & Operations Mgt. Unit Working Paper , Pp. 21-125. Publisher's VersionAbstract
Do virtual, yet informal and synchronous, interactions affect individual performance outcomes of organizational newcomers? We report results from a randomized field experiment conducted at a large global organization that estimates the performance effects of “virtual water coolers” for remote interns participating in the firm’s flagship summer internship program. Findings indicate that interns who had randomized opportunities to interact synchronously and informally with senior managers were significantly more likely to receive offers for full-time employment, achieved higher weekly performance ratings, and had more positive attitudes toward their remote internships. Further, we observed stronger results when the interns and senior managers were demographically similar. Secondary results also hint at a possible abductive explanation of the performance effects: virtual watercoolers between interns and senior managers may have facilitated knowledge and advice sharing. This study demonstrates that hosting brief virtual water cooler sessions with senior managers might have job and career benefits for organizational newcomers working in remote workplaces, an insight with immediate managerial relevance.

Education agencies are evaluating teachers using student achievement data. However, very little is known about the comparability of test-based or "value-added" metrics across districts and the extent to which they capture variability in classroom practices. Drawing on data from four urban districts, we find that teachers are categorized differently when compared within versus across districts. In addition, analyses of scores from two observation instruments, as well qualitative viewing of lesson videos identify stark differences in instructional practices across districts among teachers who receive similar within-district value-added rankings. Exploratory analyses suggest that these patterns are not explained by observable background characteristics of teachers and that factors beyond labor market sorting likely play a key role.

WRITING REVENANTS: Corporealizing Memory in the Francophone Theater of Wajdi Mouawad
Rachel Morris Watson. Working Paper. “WRITING REVENANTS: Corporealizing Memory in the Francophone Theater of Wajdi Mouawad”. Full TextAbstract
The corporeality of language is primordial in theater: the intersection of body and text is essential to performance. In Western theater traditions, from Ancient Greek tragedy to contemporary French and Francophone political theater, the body, more specifically the dead body (by way of murder, war, or sacrifice) is also frequently the point of departure for dramatic conflict and eventual moral or political reflection. In the tetralogy Le sang des promesses, by the Canadian-Lebanese playwright Wajdi Mouawad, revenants, the corps(es) of characters, haunt the stage. Using Incendies, the second play of the series, as a case study, this paper examines the importance of the corps(e) and its connection to writing in Mouawad’s work. The staging of the revenant in Incendies creates a memory space for those lost to real-life geopolitical conflicts. The re-membering of this body, through the writing of and embodiment on stage of this corpse’s members, aims to purge the individual and collective pain of sociopolitical trauma. Additionally, the revenant fractures temporal space and linear narrative, creating a thickness of time, space, and récit by comingling present and past. The dramatic action and the textual tissue of the play are determined by the presence, physical and metaphorical, of this body. Finally, the paper asserts that, in Incendies, an equivalence is established between the practice of writing and our ability to bury our dead, to allow the corpses and our collective conscious to rest in peace through textual remembrance.

Publisher's VersionAbstract

The Cambrian Stage 3 Chengjiang biota in South China is one of the most influential Konservat Lagerstatten worldwide thanks to the fossilization of diverse nonbiomineralizing organisms through pyritization. Despite their contributions to understanding the evolution of early animals, several Chengjiang species remain poorly known due to their scarcity and/or incomplete preservation. Here, we use micro-computed tomography to reveal in detail the ventral appendage organization of the enigmatic non-trilobite artiopod Pygmaclypeatus daziensis, one of the rarest euarthropods in Chengjiang, and explore its functional ecology and broader evolutionary significance. P. daziensis possesses a set of uniramous antennae and 14 pairs of post-antennal biramous appendages, the latter of which show an unexpectedly high degree of heteronomy based on the localized differentiation of the protopodite, endopod and exopod along the antero-posterior body axis. The small body size (less than 2 cm), presence of delicate spinose endites, and well-developed exopods with multiple paddle-shaped lamellae on the appendages of P. daziensis indicate a nekto-benthic mode of life, and a scavenging/detritus feeding strategy. P. daziensis shows that appendage heteronomy is phylogenetically widespread within Artiopoda, the megadiverse clade that includes trilobites and their relatives with nonbiomineralizing exoskeletons and suggests that a single exopod lobe with paddle like lamellae is ancestral for this clade.

As the world’s largest CO2 emitter, China’s ability to decarbonize its energy system strongly affects the prospect of achieving the 1.5oC limit in global average-surface-temperature rise. Understanding technically-feasible, cost-competitive and grid-compatible solar-photovoltaic (PV) power potentials spatiotemporally is critical for China’s future energy pathway. This study develops an integrated model to evaluate the spatiotemporal evolution of the techno-economic-grid PV potentials in China during 2020-2060 under the assumption of continued cost degression in line with the trends of the past decade. The model considers the spatialized technical constraints, up-to-date economic parameters and dynamic hourly interactions with the power grid. In contrast to the PV production of 0.26 PWh in 2020, results suggest that China’s technical potential will increase from 99.2 PWh in 2020 to 146.1 PWh in 2060 along with technical advances, and the national-average power price could decrease from 4.9 to 0.4 cents/kWh during the same period. About 78.6% (79.7 PWh) of China’s technical potential will realize price parity to coal-fired power in 2021, with price parity achieved nationwide by 2023. The cost advantage of solar-PV allows for coupling with storage to generate cost-competitive and grid-compatible electricity. The combined systems potentially could supply 7.2 PWh of grid-compatible electricity in 2060 to meet 43.2% of the country’s electricity demand at a price below 2.5 cents/kWh. The findings highlight a crucial energy transition point, not only for China but for other countries, at which combined solar power and storage systems become a cheaper alternative to coal-fired electricity and a more grid-compatible option.

Hansen (2014) states that foreign language studies must learn to conceive of culture as an open, multi-voiced and dialogical interaction full of contradictions”(p. 9). One advocated approach to teach transcultural understanding is through the analysis of cultural narratives (MLA report, 2007, p. 4). Kearney (2012) defines cultural narratives as “the multiple (sometimes competing), conventional storylines that cultural groups produce and use to make sense of and attribute meaning to their shared experiences” (p. 59). This article will showcase a project in a beginning French course in which four different Parisians from the same quarter were asked to document and share the stories of their lives with a virtual reality (VR) camera. Findings reveal that the VR narratives allowed students to envision, experience, and understand diverse facets of Parisian culture
and more vividly imagine their future role as participants in Parisian communities.
