Developmental Coordination Disorder (DCD) is a common neurodevelopmental disorder featuring deficits in motor coordination and motor timing among children. Deficits in rhythmic tracking, including ...perceptually tracking and synchronizing action with auditory rhythms, have been studied in a wide range of motor disorders, providing a foundation for developing rehabilitation programs incorporating auditory rhythms. We tested whether DCD also features these auditory-motor deficits among 7-10 year-old children. In a speech recognition task with no overt motor component, modulating the speech rhythm interfered more with the performance of children at risk for DCD than typically developing (TD) children. A set of auditory-motor tapping tasks further showed that, although children at risk for DCD performed worse than TD children in general, the presence of an auditory rhythmic cue (isochronous metronome or music) facilitated the temporal consistency of tapping. Finally, accuracy in the recognition of rhythmically modulated speech and tapping consistency correlated with performance on the standardized motor assessment. Together, the results show auditory rhythmic regularity benefits auditory perception and auditory-motor coordination in children at risk for DCD. This provides a foundation for future clinical studies to develop evidence-based interventions involving auditory-motor rhythmic coordination for children with DCD.
Recent research has implicated the nucleus accumbens (NAc) in consolidating recently acquired goal-directed appetitive memories, including spatial learning and other instrumental processes. However, ...an important but unresolved issue is whether this forebrain structure also contributes to the consolidation of fundamental forms of appetitive learning acquired by Pavlovian associative processes. In addition, although dopaminergic and glutamatergic influences in the NAc have been implicated in instrumental learning, it is unclear whether similar mechanisms operate during Pavlovian conditioning. To evaluate these issues, the effects of posttraining intra-NAc infusions of D1, D2, and NMDA receptor antagonists, as well as D-amphetamine, were determined on Pavlovian autoshaping in rats, which assesses learning by discriminated approach behavior to a visual conditioned stimulus predictive of food reward. Intracerebral infusions were given either immediately after each conditioning session to disrupt early memory consolidation or after a delay of 24 h. Findings indicate that immediate, but not delayed, infusions of both D1 (SCH 23390) and NMDA (AP-5) receptor antagonists significantly impair learning on this task. By contrast, amphetamine and the D2 receptor antagonist sulpiride were without significant effect. These findings provide the most direct demonstration to date that D1 and NMDA receptors in the NAc contribute to, and are necessary for, the early consolidation of appetitive Pavlovian learning.

Abstract
This essay argues for shifting the focus of a literary theory and criticism course to the institutional, social, and historical forces that shape English studies. Rather than promoting ...disciplinary introspection, the authors understand their approach as raising questions regarding elitism and the long historical entanglement of knowledge making with the interlocking forces of racism, colonialism, and sexism.
Maximum thermoelectric energy conversion efficiencies are calculated using the conventional “constant property” model and the recently proposed “cumulative/average property” model (Kim et al. in Proc ...Natl Acad Sci USA 112:8205,
2015
) for 18 high-performance thermoelectric materials. We find that the constant property model generally predicts higher energy conversion efficiency for nearly all materials and temperature differences studied. Although significant deviations are observed in some cases, on average the constant property model predicts an efficiency that is a factor of 1.16 larger than that predicted by the average property model, with even lower deviations for temperature differences typical of energy harvesting applications. Based on our analysis, we conclude that the conventional dimensionless figure of merit
ZT
obtained from the constant property model, while not applicable for some materials with strongly temperature-dependent thermoelectric properties, remains a simple yet useful metric for initial evaluation and/or comparison of thermoelectric materials, provided the
ZT
at the average temperature of projected operation, not the peak
ZT
, is used.

Wanstead House was built by Colen Campbell between 1713-20 for Richard Child, later Viscount Castlemaine and 1st Earl Tylney. The house, furnished by leading designer of the Georgian period, William ...Kent, was recognized as one of the ‘noblest houses in Europe’ and displayed the same level of opulence as major seats such as Chatsworth or Houghton, but within the peripheries of London. The Wanstead landscape was created by important designers George London and Henry Wise, Charles Bridgeman, William Kent and Humphry Repton. However, in June 1822, the entire contents of Wanstead was sold in order to settle significant debts accumulated by its owners, William and Catherine Pole Tylney Long Wellesley. Two years later, the house was demolished, and the building material was sold. Due to its demolition and the decline of its landscape, Wanstead is a major loss to academic studies of the eighteenth-century estate. This thesis draws on a broad range of widely dispersed material evidence to present a much-needed chronological history of Wanstead. It seeks to ‘animate’ the property, fully considering it as a lived space, and as a mutable environment, in the constant process of development. Other themes of this thesis include social status and the country house, estate management, and the significance of geographical location. The introduction provides an account of the 1822 Wanstead sale and outlines the historiography and methodology. Due to the nature of the dispersed evidence, the methodological discussion is necessarily detailed, addressing the challenges and importance of cross-examining material for this study of a lost house. Chapter one examines Josiah Child’s acquisition of Wanstead, and how he laid the foundations for the estate’s future glory. Chapters two and three address improvements carried out by Richard Child between 1704 and 1750.Chapter four is a study of the ownerships of the second half of the eighteenth century. The conclusion returns to the Wanstead sale, evaluating the impact of Wanstead’s loss and assessing how the study of such a lost house can contribute to our understanding of eighteenth-century estates more broadly.
