Examining Effective Intervention Practices for Communication Impairment in Autism Spectrum Disorder

This article describes effective communication-related practices by reviewing specific evidence-based techniques, sharing how these techniques have been used in various treatment approaches, and discussing a constellation of general principles vital to treatment success. A comprehensive model of service delivery is provided to illustrate these key features of effective practice within the ecological and cultural contexts of families and their everyday lives.     

Mind, Brain, and Education: Building a Scientific Groundwork for Learning and Teaching1

ABSTRACT— The primary goal of the emerging field of Mind, Brain, and Education is to join biology, cognitive science, development, and education in order to create a sound grounding of education in research. The growing, worldwide movement needs to avoid the myths and distortions of popular conceptions of brain and genetics and build on the best integration of research with practice, creating a strong infrastructure that joins scientists with educators to study effective learning and teaching in educational settings. Science and practice together provide many potentially powerful tools to improve education. Neuroscience and genetics make possible analysis of the "black box" of biological processes that underpin learning. Understanding the biology of abilities and disabilities helps educators and parents to facilitate individual students' learning and development. Cognitive science provides analyses of the mental models/metaphors that pervade meaning making in human cultures, creating tools for avoiding unconscious distortions and crafting effective educational tools. Developmental and learning science produce tools to analyze learning pathways, including both shared patterns and learning differences. To reach the potential of grounding education effectively in research requires improving the infrastructure by creating (a) research schools where practice and science jointly shape educational research, (b) shared databases on learning and development, and (c) a new profession of educational engineers or translators to facilitate connecting research with practice and policy.     

Patent trolls on markets for technology - An empirical analysis of NPEs’ patent acquisitions

Patent trolls, or NPEs, appropriate profits from innovation solely by enforcing patents against infringers. They are often characterized as relying on low-quality patents, an assessment that, if correct, would imply that eradicating such patents would effectively terminate the NPE business. In this paper, we shed light on this issue by empirically analyzing NPEs’ patent acquisitions. We draw on a unique dataset of 392 U.S. patents acquired by known NPEs between 1997 and 2006, which we compare to three control groups of 784 U.S. patents each acquired by practicing firms. We find that the probability that a traded patent is acquired by an NPE rather than a practicing entity increases in the scope of the patent, in the patent density of its technology field and, contrary to common belief, in the patent's technological quality. Our findings thus support recent theoretical propositions about the NPE business model, showing that NPEs procure patents that are more likely to be infringed, harder to substitute for, and robust to legal challenges. The fact that NPE-acquired patents are of significantly higher quality than those in the control group implies that elevating minimum patent quality will not put an end to the NPE business, and suggests that this business is sustainable in the long run. We furthermore discuss the fact that NPEs are peculiar players on markets for technology insofar as they are solely interested in the exclusion right, not in the underlying knowledge. We posit that transactions involving NPEs may only be the tip of the iceberg of “patent-only” transactions, a conjecture with strong implications for the efficiency and the study of markets for technologies. Managerial and policy implications are discussed.     

Total quality management (TQM) in a hospital library: identifying service benchmarks.

Hospitals are turning to total quality management (TQM) to lower costs of providing care. A hospital library in a TQM environment needs to embrace corporate goals while maintaining its accountability as a contributor to quality patient care. Alliant Health System (AHS) Library at Norton Hospital and Kosair Children's Hospital in Louisville, Kentucky, conducted a study to establish TQM benchmarks and to examine the significance of its role in clinical care. Using a methodology designed to allow both library user and nonuser to respond, 2,091 surveys were distributed to physicians and nursing and allied health personnel. Areas surveyed included frequency of library use, impact of information received on clinical judgments, cognitive value of the information, and satisfaction with library products and services. Results confirm that the library has a substantial clinical role. Eighty-eight percent of reporting physicians agreed that information from the library contributed to higher quality care. Nursing and allied health were less convinced of the importance of the library's clinical role. Sixty-nine percent of nursing personnel and 58% of allied health personnel agreed that the library contributed to higher quality care. Nursing and allied health personnel also used the library less frequently than physicians. With these results as benchmarks, improving the clinical role of the library will take commitment to the TQM process and a willingness to change.

Fostering scientific reasoning in education – meta-analytic evidence from intervention studies

Scientific reasoning skills are not just for researchers, they are also increasingly relevant for making informed decisions in our everyday lives. How can these skills be facilitated? The current state of research on supporting scientific reasoning includes intervention studies but lacks an integrated analysis of the approaches to foster scientific reasoning in primary through secondary education. This meta-analysis evaluates effect sizes taken from 30 interventions in experimental and quasi-experimental studies and shows a medium mean effect of interventions on scientific reasoning. Interventions successfully facilitate scientific discovery, scientific argumentation, or nature of science in all age groups. Moderator analyses show that interventions set in constructive and interactive learning activities yield positive effects but do not differ substantially. Although the meta-analysis is limited by the number of studies included, we can conclude that scientific reasoning can successfully be facilitated and we show which characteristics are beneficial in educational interventions.     

Transient and Robust Knowledge: Contextual Support and the Dynamics of Children's Reasoning About Density

ABSTRACT— Contextual support for performance and understanding plays an important role in learning and teaching. This study investigated the temporal course of the effects of support—how it affects complexity and correctness of judgments about density in kindergarten ( n = 35) and second-grade ( n = 29) children. In the experimental group, a teacher provided support through modeling more complex reasoning about why objects sink or float. Children's complexity judgments increased sharply with support compared to no support, although their predictions about whether objects would sink or float were mostly correct from the start. Following the support event, children showed a sudden jump in complexity of explanations, which was transient for most children, who showed either rapid decrease or some oscillation and then decrease. A few sustained the high-level explanation after the jump, showing robust knowledge. That is, patterns of performance across trials were primarily nonlinear, following mostly cubic or quadratic change. In addition, second-graders had a more complex understanding of density than did kindergarteners. Findings indicate that children's concepts are dynamic rather than static, as evidenced by the strong but transient effects of support for most students. To move from transient to robust knowledge requires the building of knowledge and skill over time.
