TEACHING COMPUTER-BASED SPELLING TO INDIVIDUALS WITH DEVELOPMENTAL AND HEARING DISABILITIES: TRANSFER OF STIMULUS CONTROL TO WRITING TASKS

Computer-based instruction may yield widely useful handwritten spelling. Illustrative cases involved individuals with mental retardation and hearing impairments. The participant in Study 1 matched computer pictures and printed words to one another but did not spell the words to pictures. Spelling was then taught using a computerized procedure. In general, increases in the accuracy of computer spelling were accompanied by improvements in written spelling to pictures. Study 2 extended these results with a 2nd participant. After initial training, spelling improved in the context of a retrieval task in which the participant (a) wrote a list of the names of objects displayed on a table, (b) selected the objects from a shelf, and (c) returned the objects to the table. Nearly perfect accuracy scores declined on some retrieval trials conducted without a list, suggesting that the list may have served a mediating function during retrieval. Transfer of stimulus control of computer-based teaching to the retrieval task may have been attributable to the existence of stimulus classes involving pictures, objects, and printed words.     

Estimating Causal Impacts of School Counselors With Regression Discontinuity Designs

This article presents a causal regression discontinuity framework for quantifying the impact of high school counselors on students’ education outcomes. To demonstrate this method, the authors used data from the National Center for Education Statistics’ Schools and Staffing Survey (SASS). Using high school counselor staffing counts and 4‐year college‐going rates collected through the SASS, the authors found that an additional high school counselor is predicted to induce a 10 percentage point increase in 4‐year college enrollment.     

Comparing Three Methods to Measure a Balanced Time Perspective: The Relationship Between a Balanced Time Perspective and Subjective Well-Being

The goals of this study were to determine the relations between having a balanced time perspective (BTP) with various measures of subjective well-being (SWB) and to test how various operationalizations of a BTP might impact the relation between having a BTP and SWB. We operationalized a balanced time perspective using: (a) Drake et al.’s Time Soc 17(1):47–61, (2008) cut-off-point method, (b) Boniwell et al.’s J Posit Psychol 5(1):24–40, (2010) suggestion of using a hierarchical cluster analysis, and (c) a deviation from a balanced time perspective (DBTP; Stolarski et al. Time Soc, 2011). The results demonstrated that having a BTP is related to increased satisfaction with life, happiness, positive affect, psychological need satisfaction, self-determination, vitality, and gratitude as well as decreased negative affect. Also, the DBTP was the best predictor of SWB. We discuss why individuals with a BTP are likely to be happier in life.     

Composition and magnetic character of nanometre-size Cu precipitates in reactor pressure vessel steels: Implications for nuclear power plant lifetime extension

The sensitivity of positrons to nanometre-size Cu precipitates in Fe alloys has enabled us to apply a novel spin-polarized element-specific method to probe the composition and magnetic character of the precipitates responsible for reactor pressure vessel (RPV) steel embrittlement. The results clearly show that the precipitates are non-magnetic and place an upper limit of about 10at% on their Fe content. The practical implication of this result is that the Cu precipitate contribution to RPV steel embrittlement saturates is not expected to contribute further during lifetime extension. Our study demonstrates that polarized positrons can be used as a powerful probe of the magnetic character of nanoscale materials, even those embedded in a strongly magnetic host.     

Emergentism and supervenience physicalism

I argue that it is intuitive and useful to think about composition in the light of the familiar functionalist distinction between role and occupant. This involves factoring the standard notion of parthood into two related notions: being a parthood slot and occupying a parthood slot. One thing is part of another just in case it fills one of that thing's parthood slots. This move opens room to rethink mereology in various ways, and, in particular, to see the mereological structure of a composite as potentially outreaching the individual entities that are its parts. I sketch one formal system that allows things to have individual entities as parts multiple times over. This is particularly useful to David Armstrong, given Lewis's charge that his structural universals must do exactly that. I close by reflecting upon the nature and point of formal mereology.     

Intrusive thoughts and avoidance in breast cancer: Individual differences and association with psychological distress

Abstract

Eighty-five women with newly diagnosed breast cancer were classified on the basis of high and low levels of cancer-related intrusive thoughts and avoidance at diagnosis, and their psychological adjustment was studied prospectively at 3 and 6 months post diagnosis. Patients who initially reported high levels of both intrusive thoughts and avoidance and those who reported high levels of intrusive thoughts but low avoidance experienced the highest levels of anxiety and depression symptoms, and continued intrusive thoughts and avoidance. Patients who were high in avoidance but low in intrusive thoughts also experienced adjustment problems, including increased intrusive thoughts, when compared with patients who were low in both types of symptoms. The findings highlight the value of considering subgroup differences in patterns of intrusion and avoidance as predictors of subsequent psychological adjustment to breast cancer.     

Learning and the Development of Meaning: Husserl and Merleau‐Ponty on the Temporality of Perception and Habit

In this paper, I argue that the temporal openness of perceptual experience provides insight into the basic structure of learning. I draw on Husserl's account of the mutability of the retained past in Analyses Concerning Passive and Active Synthesis, and Merleau‐Ponty's account of the perceptual field, as well as his remarks on habit, in Phenomenology of Perception, in order to elucidate the relation between the perceptual past and the future it portends. More specifically, I argue that retention and habituation in perceptual experience open dimensions of meaning that transform the initial, initiating, experiences in which meaning is first established. As a result, our experience of meaning is always subject to further development that we cannot anticipate. This temporal openness has consequences for our learning to navigate a perceptual field, but also, I argue, for our developing more complex ways of engaging with the world. Specifically, I show how learning requires that we commit ourselves to an object or task before we are in a position to recognize the implications or significance of our commitment. I further consider the role that others play in the inherent openness of learning to the development of new meaning.
