Comparing Skill Acquisition Under Varying Onsets of Differential Reinforcement: A Preliminary Analysis
The purpose of the current study was to evaluate the effect of implementing differential reinforcement at different times relative to the onset of teaching new skills to learners with autism spectrum disorder. Specifically, we first determined the most efficient differential reinforcement arrangement for each participant. Using the most efficient arrangement, we evaluated if differential reinforcement from the immediate onset, early onset, or late onset is the most efficient for learners to acquire a new skill. Three children diagnosed with autism spectrum disorder who have a history of receiving intervention based on the principles of applied behavior analysis participated in this study. The immediate onset of differential reinforcement resulted in the most efficient instruction in 6 of 7 comparisons. The results are discussed in light of previous studies and suggestions for future research are provided
Learning from a fool: searching for the 'unmanaged' context for radical learning
Drawing on the existing theorizing of organizational learning from a radical perspective, this article attempts to problematize such notion of learning and position it within the existing organizational contexts informed by divergent types of rationality. The study scrutinizes these frameworks with a view to reflect on the potentiality for radical learning to occur within them. In this vein, the conceptual analysis of non-technical and non-marginal notions, namely, ‘spirituality’, ‘luck’ and ‘wisdom’, in different modes of rationality is conducted. This article demonstrates that since the conceptual inclusiveness is entailed by the specificity of sensemaking mechanisms, which these modes employ, the analysed notions can be approached as their litmus paper. The functionalist rationality types are found to be incommensurate with exigencies of the radical context for learning. In pursue of the conducive area for radical learning, the notions of unmanaged organization and the technology of foolishness provide the theoretical frame for the study, and their joint sensemaking context is discussed using examples. This unmanaged space driven by inclusive foolishness is recognized as one that enables the liminal sensemaking processes conducive for radical learning to occur

The DREAM Dataset: Supporting a data-driven study of autism spectrum disorder and robot enhanced therapy
We present a dataset of behavioral data recorded from 61 children diagnosed with Autism Spectrum Disorder (ASD). The data was collected during a large-scale evaluation of Robot Enhanced Therapy (RET). The dataset covers over 3000 therapy sessions and more than 300 hours of therapy. Half of the children interacted with the social robot NAO supervised by a therapist. The other half, constituting a control group, interacted directly with a therapist. Both groups followed the Applied Behavior Analysis (ABA) protocol. Each session was recorded with three RGB cameras and two RGBD (Kinect) cameras, providing detailed information of children’s behavior during therapy. This public release of the dataset comprises body motion, head position and orientation, and eye gaze variables, all specified as 3D data in a joint frame of reference. In addition, metadata including participant age, gender, and autism diagnosis (ADOS) variables are included. We release this data with the hope of supporting further data-driven studies towards improved therapy methods as well as a better understanding of ASD in general.CC BY 4.0DREAM - Development of robot-enhanced therapy for children with autism spectrum disorders

Comparative genome structure, secondary metabolite, and effector coding capacity across Cochliobolus pathogens.
The genomes of five Cochliobolus heterostrophus strains, two Cochliobolus sativus strains, three additional Cochliobolus species (Cochliobolus victoriae, Cochliobolus carbonum, Cochliobolus miyabeanus), and closely related Setosphaeria turcica were sequenced at the Joint Genome Institute (JGI). The datasets were used to identify SNPs between strains and species, unique genomic regions, core secondary metabolism genes, and small secreted protein (SSP) candidate effector encoding genes with a view towards pinpointing structural elements and gene content associated with specificity of these closely related fungi to different cereal hosts. Whole-genome alignment shows that three to five percent of each genome differs between strains of the same species, while a quarter of each genome differs between species. On average, SNP counts among field isolates of the same C. heterostrophus species are more than 25× higher than those between inbred lines and 50× lower than SNPs between Cochliobolus species. The suites of nonribosomal peptide synthetase (NRPS), polyketide synthase (PKS), and SSP-encoding genes are astoundingly diverse among species but remarkably conserved among isolates of the same species, whether inbred or field strains, except for defining examples that map to unique genomic regions. Functional analysis of several strain-unique PKSs and NRPSs reveal a strong correlation with a role in virulence
