Letter From the Editor
It is a pleasure to compose a letter to you at the outset of the 2016-2017 academic year. In composing this, my first letter as Managing Editor of ICCTE-J, I envision each of you sitting in front of a screen, scrolling through the latest journal offerings in search of new information or insight. I wonder what brief words I might offer to encourage you in the face of all we undertake to launch a new academic year and deal profitably with lifeās many challenges. And I think it is this: we serve a marvelous and sovereign God who loves each one with abandon. This is what grounds us in the educational work of our hands, and is our sustaining grace despite political tumult, racial tensions, social inequities, and all the needs our students carry into our classrooms
āWe Want to Tell the Worldā: One Teacherās Experience with the Power of Petey
āThat oneās Petey Corbin. Heās an idiot retard, but a friendly oneāyou know, laughs and smiles a lot. Sometimes you swear heās thinking, but itās just conditioning. They used to get him up every day and put him in a wheelchair. Lucky for us, they stopped that.ā (Mikaelsen, 1998, p. 113)
I steal a glance up from the page of the book I am reading aloud to take stock of my fourth-gradersā reactions. They sit just below where I am curled on the couch. The lights are off, except for a single reading lamp. This is our daily read-aloud ritual; a time of togetherness that quietly opens the door to great possibilities. Many are hugging their knees and staring into the middle distance, thoughtful. Some are slightly agape; all are solemn. āWhy am I reading those words, āidiotā and āretardā?ā I ask. āWhat does it suggest to you about what people thought of Petey?
Unsupervised Learning via Total Correlation Explanation
Learning by children and animals occurs effortlessly and largely without
obvious supervision. Successes in automating supervised learning have not
translated to the more ambiguous realm of unsupervised learning where goals and
labels are not provided. Barlow (1961) suggested that the signal that brains
leverage for unsupervised learning is dependence, or redundancy, in the sensory
environment. Dependence can be characterized using the information-theoretic
multivariate mutual information measure called total correlation. The principle
of Total Cor-relation Ex-planation (CorEx) is to learn representations of data
that "explain" as much dependence in the data as possible. We review some
manifestations of this principle along with successes in unsupervised learning
problems across diverse domains including human behavior, biology, and
language.Comment: Invited contribution for IJCAI 2017 Early Career Spotlight. 5 pages,

Professional Development\u27s Complex Ecology: Examining a Whole-School Balanced Literacy Professional Development
This descriptive study reports on the structure and implementation of a school wide professional development model in a southwest public elementary school. The professional development effort was designed to support educatorsā understanding and teaching of balanced literacy. The paper reports on the components of this professional development and discusses the strengths of this model in relation to educational research and findings on professional development. We conclude by discussing this model from the perspective of involved administration, facilitators, and teachers, as they consider the process of crossing the borders from professional development into their classrooms. The study is strengthened by teachersā opinions about the model in their school

Relaxed uncertainty relations and information processing
We consider a range of "theories" that violate the uncertainty relation for
anti-commuting observables derived in [JMP, 49, 062105 (2008)]. We first show
that Tsirelson's bound for the CHSH inequality can be derived from this
uncertainty relation, and that relaxing this relation allows for non-local
correlations that are stronger than what can be obtained in quantum mechanics.
We continue to construct a hierarchy of related non-signaling theories, and
show that on one hand they admit superstrong random access encodings and
exponential savings for a particular communication problem, while on the other
hand it becomes much harder in these theories to learn a state. We show that
the existence of these effects stems from the absence of certain constraints on
the expectation values of commuting measurements from our non-signaling
theories that are present in quantum theory.Comment: 33 pages, 1 figure. v2: improved notation, to appear in QI
