TL;DR: This paper presents a novel approach to task management that automates the creation and maintenance of task representations and describes a feasibility study that demonstrates the actual utility (in terms of overhead reduction) and perceived utility of the system.
Abstract: Recent HCI research shows strong interest in task management systems (e.g. [19, 27]) that support the multi-tasked nature of information work [13]. These systems either require users to manually create and maintain task representations or they depend on explicit user cues to guide the creation and maintenance process. To access and use the task representations in these systems, users must also specify their current task. This interaction overhead inhibits the adoption of these systems. In this paper, we present a novel approach to task management that automates the creation and maintenance of task representations. Our system supports the user by making commonly used information more "ready-at-hand" through an intuitive visualization of their task representations. Users can correct and organize their task representations by directly manipulating the visualization; however, this interaction is not required. We describe a feasibility study that demonstrates the actual utility (in terms of overhead reduction) and perceived utility of our system.

TL;DR: The authors found that there is more developmentally advanced use of tense-aspect morphology on conceptually demanding tasks compared with less demanding tasks, and a trend to more target-like use of lexicalization patterns for referring to motion on complex tasks.
Abstract: The Cognition Hypothesis (Robinson 2005) claims that pedagogic tasks should be sequenced for learners in an order of increasing cognitive complexity, and that along resource-directing dimensions of task demands increasing effort at conceptualization promotes more complex and grammaticized second language (L2) speech production. This article summarizes results of two studies that measured the effects of increasing the complexity of task demands in conceptual domains using specific measures of the accuracy and complexity of speech. These measures are motivated by research into the development of tense–aspect morphology when referring to time (Shirai 2002), and by typological, cross-linguistic research into using lexicalization patterns when referring to motion (Cadierno 2008). Results show there is more developmentally advanced use of tense–aspect morphology on conceptually demanding tasks compared with less demanding tasks, and a trend to more target-like-use of lexicalization patterns for referring to motion on complex tasks.

TL;DR: Using conversation analysis and situated learning theory, this paper analyzed the peer dyadic interactions of one adult learner of English in class periods 16 months apart and presented microgenetic and longitudinal perspectives on the learner's increasing participation in his classroom communities of practice.
Abstract: Using conversation analysis and situated learning theory, in this paper we analyze the peer dyadic interactions of one adult learner of English in class periods 16 months apart. The analyses in the paper present microgenetic and longitudinal perspectives on the learner's increasing participation in his classroom communities of practice. The focus of the analyses is on the language practices for a social action that is not taught explicitly by the instructors—disengaging from teacher-assigned dyadic task interactions. The tasks from which the learner disengages are serial dyadic interaction tasks. In these tasks, a learner engages with a number of different classmates doing the same task consecutively. The serial dyadic interaction task design is shown to offer students ongoing opportunities to develop interactional routines for social actions and language practices needed to accomplish habitual actions such as opening and disengaging from their dyadic task interactions.

TL;DR: In this article, the authors examined whether more complex tasks (a) lead to greater incidence of pronunciation-focused language-related episodes (LREs) and (b) positively impact accuracy of phonetic form during task completion.
Abstract: This study tests the theoretical predictions regarding effects of increasing task complexity (Robinson, 2001a, 2001b, 2007, 2010; Robinson & Gilabert, 2007) for second language (L2) pronunciation. Specifically, we examine whether more complex tasks (a) lead to greater incidence of pronunciation-focused language-related episodes (LREs) and (b) positively impact accuracy of phonetic form during task completion. Seventeen dyads of intermediate L2 Spanish learners completed simple (+few elements) and complex (-few elements) information-gap map tasks in which the pronunciation of Spanish vowels was made task essential through the inclusion of minimal pair street names (e.g., Calle Copa “Copa Street” and Calle Capa “Capa Street”). Results revealed no statistical difference in learner-produced pronunciation-related LREs in the simple and complex tasks. Vowel production, however, moved in a targetlike direction for one of five segments (/e/) during the complex task. Results therefore point to some benefits of task complexity manipulations for L2 pronunciation.

TL;DR: In this paper, an example system identifies a set of tasks as being designated for execution and schedules an execution of the first task, which is scheduled to use a particular data processing resource.
Abstract: An example system identifies a set of tasks as being designated for execution, and the set of tasks includes a first task and a second task. The example system accesses task dependency data that corresponds to the second task and indicates that the first task is to be executed prior to the second task. The example system, based on the task dependency data, generates a task dependency model of the set of tasks. The dependency model indicates that the first task is to be executed prior to the second task. The example system schedules an execution of the first task, which is scheduled to use a particular data processing resource. The scheduling is based on the dependency model.
