A survey and analysis of the place-names of Staffordshire

This main body of this work consists of a gazetteer of all of the main, and many of the minor, place-names of Staffordshire (meaning any places which are or were at any time known to have been in what was, or became, Staffordshire), with early spellings, and observations on the likely or possible derivation of those names, often in a rather more discursive form than standard works on place-names, particularly where uncertainty exists as to the derivation. Early place-name spellings have been collected from many sources, primarily the volumes of the Staffordshire Historical Collections, but also the volumes of archive indexes at Staffordshire Record Office, supplemented by Staffordshire place-names extracted from other sources, such as the Transactions of the Shropshire Archaeological Society and the printed Cartularies of Haughmond and Lilleshall Abbeys, both in Shropshire, and from the editorial notes produced during research by the Victoria County History of Staffordshire team. Those slips often contain early place-name spellings. The Staffordshire Encyclopaedia, a monumental compilation of material on the history and folk-lore of Staffordshire published in 2000, has provided a valuable key to material relating indirectly to place-name research, such as topographical and archaeological features. Other material has been extracted from early work on the place-names of Staffordshire and adjoining counties by W. H. Duignan and from other volumes on place-name research and the journals of The English Place-Name Society and The Society for Name Studies in Britain and Ireland. The analysis considers the early history of the county of Stafford, and reviews the place-name evidence under various headings, including the relationship of particular elements to Roman roads, the ancient boundaries, the Hundred meeting-places, and discussions on Scandinavian and French names and those considered to provide evidence of pagan religion. The analysis incorporates a list of personal names found in Staffordshire place-names, and of topographical and other elements

Does patient age affect survival after radical cystectomy?

OBJECTIVE To analyse the impact of patient age on survival after radical cystectomy (RC). PATIENTS AND METHODS After ethics review board approval, two databases of patients with bladder cancer (BC) undergoing RC at the University Heath Network, Toronto, Canada (1992-2008) and the University of Turku, Turku, Finland (1986-2005) were retrospectively analysed. A total of 605 patients who underwent this procedure between June 1985 and March 2010 were included. Patients were divided into four age groups: = 80 years. Demographic, clinical and pathological data were compared, as well as recurrence-free survival (RFS), disease-specific survival (DSS) and overall survival (OAS) rates. RESULTS Compared with younger patients (age = 80 years) had higher American Society of Anesthesiologists scores (P = 80 years (P = 80 years) should not be denied RC if they are deemed fit to undergo surgery. Senior adults do not suffer from adverse histopathological features as compared with younger patients

Sex differences in the timing of identification among children and adults with autism spectrum disorders

To examine differences by sex in the timing of identification of individuals with autism spectrum disorders (ASD), survey data were collected in the Netherlands from 2,275 males and females with autistic disorder, Asperger's syndrome and PDD-NOS. Among participants <18 years of age, females with Asperger's syndrome were identified later than males. Among participants ≥18 years of age, females with autistic disorder were identified later than males. In more recent years, girls with Asperger's syndrome are diagnosed later than boys, confirming earlier findings. In adults, the delayed timing of diagnosis in females with autistic disorder may be related to changing practices in diagnosis over time. Strategies for changing clinician behaviour to improve recognition of ASD in females are needed. © 2012 Springer Science+Business Media, LLC

Abnormal Frontoparietal Synaptic Gain Mediating the P300 in Patients with Psychotic Disorder and Their Unaffected Relatives

The “dysconnection hypothesis” of psychosis suggests that a disruption of functional integration underlies cognitive deficits and clinical symptoms. Impairments in the P300 potential are well documented in psychosis. Intrinsic (self-)connectivity in a frontoparietal cortical hierarchy during a P300 experiment was investigated. Dynamic Causal Modeling was used to estimate how evoked activity results from the dynamics of coupled neural populations and how neural coupling changes with the experimental factors. Twenty-four patients with psychotic disorder, twenty-four unaffected relatives, and twenty-five controls underwent EEG recordings during an auditory oddball paradigm. Sixteen frontoparietal network models (including primary auditory, superior parietal, and superior frontal sources) were analyzed and an optimal model of neural coupling, explaining diagnosis and genetic risk effects, as well as their interactions with task condition were identified. The winning model included changes in connectivity at all three hierarchical levels. Patients showed decreased self-inhibition—that is, increased cortical excitability—in left superior frontal gyrus across task conditions, compared with unaffected participants. Relatives had similar increases in excitability in left superior frontal and right superior parietal sources, and a reversal of the normal synaptic gain changes in response to targets relative to standard tones. It was confirmed that both subjects with psychotic disorder and their relatives show a context-independent loss of synaptic gain control at the highest hierarchy levels. The relatives also showed abnormal gain modulation responses to task-relevant stimuli. These may be caused by NMDA-receptor and/or GABAergic pathologies that change the excitability of superficial pyramidal cells and may be a potential biological marker for psychosis

“Others-in-Law”: Legalism in the Economy of Religious Differences

Religious legalism encompasses a wide range of attitudes that assign religious meaning to legal content or to legal compliance. The phenomenology of religious legalism is assuming a significant role in various contemporary debates about legal pluralism, accommodation of religious minorities, religious freedom, and so forth. This article revises this conception and the commonplace equation of Judaism and legalism. It suggests that we ought to regard both as part of the economy of religious differences by which religious identities are expressed and defined as alternatives. The common ascription of religious legalism to Judaism (and Islam) is criticized here through a historical analysis of the law-religion-identity matrix in three cultural settings: late ancient Judeo-Hellenic, medieval Judeo–Arabic, and post-Reformation Europe

Task-Dependent Individual Differences in Prefrontal Connectivity

Recent advances in neuroimaging have permitted testing of hypotheses regarding the neural bases of individual differences, but this burgeoning literature has been characterized by inconsistent results. To test the hypothesis that differences in task demands could contribute to between-study variability in brain-behavior relationships, we had participants perform 2 tasks that varied in the extent of cognitive involvement. We examined connectivity between brain regions during a low-demand vigilance task and a higher-demand digit–symbol visual search task using Granger causality analysis (GCA). Our results showed 1) Significant differences in numbers of frontoparietal connections between low- and high-demand tasks 2) that GCA can detect activity changes that correspond with task-demand changes, and 3) faster participants showed more vigilance-related activity than slower participants, but less visual-search activity. These results suggest that relatively low-demand cognitive performance depends on spontaneous bidirectionally fluctuating network activity, whereas high-demand performance depends on a limited, unidirectional network. The nature of brain-behavior relationships may vary depending on the extent of cognitive demand. High-demand network activity may reflect the extent to which individuals require top-down executive guidance of behavior for successful task performance. Low-demand network activity may reflect task- and performance monitoring that minimizes executive requirements for guidance of behavior

Meta-analysis of real-time fMRI neurofeedback studies using individual participant data: How is brain regulation mediated?

An increasing number of studies using real-time fMRI neurofeedback have demonstrated that successful regulation of neural activity is possible in various brain regions. Since these studies focused on the regulated region(s), little is known about the target-independent mechanisms associated with neurofeedback-guided control of brain activation, i.e. the regulating network. While the specificity of the activation during self-regulation is an important factor, no study has effectively determined the network involved in self-regulation in general. In an effort to detect regions that are responsible for the act of brain regulation, we performed a post-hoc analysis of data involving different target regions based on studies from different research groups. We included twelve suitable studies that examined nine different target regions amounting to a total of 175 subjects and 899 neurofeedback runs. Data analysis included a standard first- (single subject, extracting main paradigm) and second-level (single subject, all runs) general linear model (GLM) analysis of all participants taking into account the individual timing. Subsequently, at the third level, a random effects model GLM included all subjects of all studies, resulting in an overall mixed effects model. Since four of the twelve studies had a reduced field of view (FoV), we repeated the same analysis in a subsample of eight studies that had a well-overlapping FoV to obtain a more global picture of self-regulation. The GLM analysis revealed that the anterior insula as well as the basal ganglia, notably the striatum, were consistently active during the regulation of brain activation across the studies. The anterior insula has been implicated in interoceptive awareness of the body and cognitive control. Basal ganglia are involved in procedural learning, visuomotor integration and other higher cognitive processes including motivation. The larger FoV analysis yielded additional activations in the anterior cingulate cortex, the dorsolateral and ventrolateral prefrontal cortex, the temporo-parietal area and the visual association areas including the temporo-occipital junction. In conclusion, we demonstrate that several key regions, such as the anterior insula and the basal ganglia, are consistently activated during self-regulation in real-time fMRI neurofeedback independent of the targeted region-of-interest. Our results imply that if the real-time fMRI neurofeedback studies target regions of this regulation network, such as the anterior insula, care should be given whether activation changes are related to successful regulation, or related to the regulation process per se. Furthermore, future research is needed to determine how activation within this regulation network is related to neurofeedback success

Computation of Conformational Coupling in Allosteric Proteins

In allosteric regulation, an effector molecule binding a protein at one site induces conformational changes, which alter structure and function at a distant active site. Two key challenges in the computational modeling of allostery are the prediction of the structure of one allosteric state starting from the structure of the other, and elucidating the mechanisms underlying the conformational coupling of the effector and active sites. Here we approach these two challenges using the Rosetta high-resolution structure prediction methodology. We find that the method can recapitulate the relaxation of effector-bound forms of single domain allosteric proteins into the corresponding ligand-free states, particularly when sampling is focused on regions known to change conformation most significantly. Analysis of the coupling between contacting pairs of residues in large ensembles of conformations spread throughout the landscape between and around the two allosteric states suggests that the transitions are built up from blocks of tightly coupled interacting sets of residues that are more loosely coupled to one another
