Delusions of grandeur and the Nancy Rothwell paradox
No full textWhile Nancy Rothwell was vice-chancellor, the University of Manchester climbed steadily up the Shanghai global rankings to 35. But there was widespread student discontent with Nancy Rothwell. Now the university languishes at 52. That gives rise to a paradox, which starts with these propositions. (A) The students are right to oppose Nancy Rothwell. (B) The university did much better in the global rankings when Rothwell was manager. (C) The best explanation for its earlier success is that Rothwell was a great manager

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Seismic facies of the Madeira Abyssal Plain: a correlation between seismic reflection profile and borehole data
No full textSeismic profiles across the Madeira Abyssal Plain show a relatively simple seismic stratigraphy in which an irregular diffractive acoustic basement is overlain by distinctive seismic units, reflecting a great thickness of ponded turbidites overlying pelagic drape. Within the uppermost ponded turbidite unit, a number of distinct, continuous, and laterally extensive reflectors are recognized. Sites 950 through 952 were drilled into these reflectors and allow dating of the beginning of large-scale turbidite emplacement on the abyssal plain and identification and dating of previously recognized seismic reflectors with a good degree of certainty. The extent and probable volume of the distinct turbidite packages can now be quantified.
The Madeira Abyssal Plain overlies oceanic crust of Cretaceous age. Five distinct seismic units, separated by prominent, continuous, laterally extensive reflectors, can be identified. The lowermost of these (Unit B), which directly overlies acoustic basement, is a variably stratified unit and contains reflectors that generally show low coherency and onlap onto basement highs. At Site 950, the upper part of Unit B consists of red pelagic clays, with thin calcareous turbidites and ash layers, of late Eocene to Oligocene age. Unit A overlies Unit B with clear unconformity, marked by a conspicuous basinwide seismic reflector (Reflector 4). Unit A is a variably stratified unit and can be divided into four seismic units, A0 through A3, separated by prominent reflectors of regional extent. These units consist of thick, ponded turbidites with pelagic intervals. Many turbidites are basinwide in extent and can be correlated between drill sites. Four main types of turbidites are recognized: volcanic-rich turbidites derived from the Canary Islands, organic-rich turbidites derived from the Northwest African Margin, calcareous turbidites derived from seamounts to the west of the plain, and turbidites of “intermediate” character. Organic-rich turbidites are the dominant type, although volcanic-rich turbidites are numerous in Units A0 through A2. Conversion of two-way traveltime to depth using shipboard sonic log data suggests that thick volcanic-rich and “intermediate” character turbidites of wide lateral extent commonly correspond to strong seismic reflectors, and that acoustically transparent intervals within Unit A correspond to intervals of predominantly organic-rich turbidites. The base of Unit A is the regionally important Reflector 4 that correlates with a distinctive calcareous bed at all three drill sites dated at 16 Ma. The seismic units can be laterally mapped using an extensive data set of seismic reflection profiles and the minimum volumes of sediments deposited within individual seismic units calculated, giving values for sediment accumulation on the plain per unit time. The data show that since the inception of the abyssal plain in the middle Miocene (16 Ma), a minimum of 19,000 km3 of sediments (turbidites and hemipelagites) have been deposited
Determination of sediment volumes, accumulation rates and turbidite emplacement frequencies on the Madeira Abyssal Plain (NE Atlantic): a correlation between seismic and borehole data
No full textThe sedimentary infill history of the Madeira Abyssal Plain (MAP) is established from correlation of ODP Leg 157 drillsites (Sites 950–952) with an almost regular grid of ∼7000 km of intermediate-resolution seismic reflection profiles covering the central part of the abyssal plain. The most conspicuous seismic reflectors bounding the seismostratigraphic units have been identified and mapped. Correlation between seismic and borehole data using synthetic seismograms allows the lithological attribution and dating of the reflectors and seismostratigraphic units. Lateral mapping and correlation of seismic units also allows both the volumes and rates of accumulation of sediments within each seismostratigraphic unit and equivalent time periods of deposition to be determined. These calculations have been corrected for the effect of compaction, calculated at around 40% at the base of the drillholes. Three main turbidite types have been identified at the drillsites and their emplacement frequency has been calculated for each site and time period. Our results show that Cretaceous oceanic crust was draped with red pelagic clays, and the fracture-zone valleys were completely infilled and levelled in a geologically rather short time, probably during the latest Oligocene and Early Miocene, by organic-rich turbidites derived from the NW African continental margin. At 16 Ma, the topography was levelled enough to allow large turbidity current flows to cover the entire plain. During the Middle and Late Miocene (16–5.9 Ma), organic-rich turbidites were emplaced on the abyssal plain at a low rate of accumulation (∼12 m/my). In the uppermost Miocene–Early Pliocene (5.9–3.6 Ma), turbidite emplacement increased markedly in both frequency and accumulation rate (e.g., ∼26 m/my for organic-rich turbidites). During this time, period emplacement of volcanic-rich turbidites also increased in volume and frequency, a trend that continued into the Pliocene. Increased volcanic-rich turbidite emplacement correlates well with increased volcanic activity on the Canary Islands, and increased organic-rich turbidite emplacement may correlate with periods of erosion on the NW African continental margin. These erosional periods may be related to global cooling and falling sea level, intensification of bottom-water currents, and enhanced upwelling on the margin

Regaining Motor Control in Musician's Dystonia by Restoring Sensorimotor Organization
No full textProfessional musicians are an excellent human model of long term effects of skilled motor training on the structure and function of the motor system. However, such effects are accompanied by an increased risk of developing motor abnormalities, in particular musician's dystonia. Previously we found that there was an expanded spatial integration of proprioceptive input into the hand area of motor cortex (sensorimotor organisation, SMO) in healthy musicians as tested with a transcranial magnetic stimulation (TMS) paradigm. In musician's dystonia, this expansion was even larger, resulting in a complete lack of somatotopic organisation. We hypothesised that the disordered motor control in musician's dystonia is a consequence of the disordered SMO.
In the present paper we test this idea by giving pianists with musician's dystonia 15 min experience of a modified proprioceptive training task. This restored SMO towards that seen in healthy pianists. Crucially, motor control of the affected task improved significantly and objectively as measured with a MIDI piano, and the amount of behavioural improvement was significantly correlated to the degree of sensorimotor re-organisation. In healthy pianists and non-musicians, the SMO and motor performance remained essentially unchanged. These findings suggest a link between the differentiation of SMO in the hand motor cortex and the degree of motor control of intensively practiced tasks in highly skilled individuals
Pragmatic Case Studies as a Source of Unity in Applied Psychology
No full textTo unify or not to unify applied psychology: that is the question. In this article we review pendulum swings in the historical efforts to answer this question—from a comprehensive, positivist, “top-down,” deductive yes between the 1930s and the early 60s, to a postmodern no since then. A rationale and proposal for a limited, “bottom-up,” inductive yes in applied psychology is then presented, employing a case-based paradigm that integrates both positivist and postmodern themes and components. This paradigm is labeled “pragmatic psychology” and, its specific use of case studies, the “Pragmatic Case Study Method” (“PCS Method”). We call for the creation of peer-reviewed journal-databases of pragmatic case studies as a foundational source of unifying applied knowledge in our discipline. As one example, the potential of the PCS Method for unifying different angles of theoretical regard is illustrated in an area of applied psychology, psychotherapy, via the case of Mrs. B. The article then turns to the broader historical and epistemological arguments for the unifying nature of the PCS Method in both applied and basic psychology.Peer reviewe
