    Increasing compliance with wearing a medical device in children with autism

    Full text link
    Health professionals often recommend the use of medical devices to assess the health, monitor the well-being, or improve the quality of life of their patients. Children with autism may present challenges in these situations as their sensory peculiarities may increase refusals to wear such devices. To address this issue, we systematically replicated prior research by examining the effects of differential reinforcement of other behavior (DRO) to increase compliance with wearing a heart rate monitor in 2 children with autism. The intervention increased compliance to 100% for both participants when an edible reinforcer was delivered every 90 s. The results indicate that DRO does not require the implementation of extinction to increase compliance with wearing a medical device. More research is needed to examine whether the reinforcement schedule can be further thinned

    Existence theorems for lagrange control problems with unbounded time domain

    Full text link
    Existence theorems are proved for usual Lagrange control systems, in which the time domain is unbounded. As usual in Lagrange problems, the cost functional is an improper integral, the state equation is a system of ordinary differential equations, with assigned boundary conditions, and constraints may be imposed on the values of the state and control variables. It is shown that the boundary conditions at infinity require a particular analysis. Problems of this form can be found in econometrics (e.g., infinite-horizon economic models) and operations research (e.g., search problems).Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45207/1/10957_2004_Article_BF00934054.pd

    Does Deep Tectonic Tremor Occur in the Central‐Eastern Mediterranean Basin?

    Tectonic tremor has been observed at the roots of many fault systems around the Pacific rim, including convergent and transform plate boundaries. The extent to which deep tremor signals are prevalent along fault systems elsewhere, including the Mediterranean basin, has not yet been documented in detail. A body of evidence suggests that tremor triggered during the surface waves of teleseismic events may commonly occur where ambient tremor during episodic tremor and slip episodes occur, suggesting triggered tremor provides a useful tool to identify regions with ambient tremor. We perform a systematic search of triggered tremor associated with large teleseismic events between 2010 and 2020 at four major fault systems within the central-eastern Mediterranean basin, namely the Hellenic and Calabrian subduction zones, and the North Anatolian and Kefalonia transform faults. In addition, we search for ambient tremor during a slow slip event in the eastern Sea of Marmara along a secondary branch of the North Anatolian Fault, and two slow slip events beneath western Peloponnese (Hellenic Subduction Zone). We find no unambiguous evidence for deep triggered tremor, nor ambient tremor. The absence of triggered tremor at the Hellenic and Calabrian subduction zones supports an interpretation of less favorable conditions for tremorgenesis in the presence of old and cold slabs. The absence of tremor along the transform faults may be due to an absence of the conditions commonly promoting tremorgenesis in such settings, including high-fluid pressures and low-differential stresses between the down-dip limit of the seismogenic layer and the continental Moho

    Small Scattered Fragments Do Not a Dwarf Make: Biological and Archaeological Data Indicate that Prehistoric Inhabitants of Palau Were Normal Sized

    Current archaeological evidence from Palau in western Micronesia indicates that the archipelago was settled around 3000–3300 BP by normal sized populations; contrary to recent claims, they did not succumb to insular dwarfism

    The ‘one who knocks’ and the ‘one who waits’: Gendered violence in Breaking Bad

    Get PDF
    This article provides a cultural criminological analysis of the acclaimed US television series, Breaking Bad. It is argued here that – as a cultural text – Breaking Bad is emblematic of an agenda for change surrounding criminological theories of peoples’ propensity to do harm to one another. To exemplify this, the show’s central (male) protagonist is revealed to undergo a complete biosocial transformation into a violent offender and, as such, to demonstrate the need for criminological theory to recognise and further reflect upon this process. However, at the same time, the (re)presented inability of the show’s female characters to do the same is indicative of a number of gender-related questions that progressive criminological theories of violence need to answer. In considering these two fields in tandem, the show’s criminological significance is established; it is symbolic of the need for criminology to afford greater recognition to the nuanced intersections of both biological and sociological factors in the genesis and evolution of violent human subjectivities
