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
Large-Scale Circulation Reversals in a 2D Rayleigh-Bénard cell
No full textWe consider the numerical simulation of a two-dimensional Rayleigh-B\'enard cell in the turbulent regime and . The flow is dominated by a large-scale inclined roll, the orientation of which switches intermittently in time. We use Proper Orthogonal Decomposition to identify the most energetic modes. We find that the first two modes respectively correspond to an antisymmetric and a symmetric mode. The next most energetic mode breaks the symmetry of the flow. During reversals, sharp variations in the temporal amplitudes of the modes are observed. We derive a low-dimensional model based on the first three most energetic modes which is able to reproduce the large-scale circulation reversals, in quantitative agreement with the simulation

We will each contribute a page to this publication, exploring what it might mean to reintroduce a sense of locality to our networks. These contributions might take the form of manifestos, essays, proposals, recipes, or personal corners of the net." -- Online publication

A-not-B error
No full textThe A-not-B reaching error has been shown to exist in most non-human species tested so far. There are a few exceptions: apes (apart from orang-utans), puppies, kittens, wolves and goats. It must be taken into account that, although there is growing number of studies investigating object permanence in a wide range of species, most of them do not use specific tests to investigate the A-not-B error. In addition the methodologies vary immensely between studies. Although many studies use the basic set of tests by Uzgiris and Hunt (1989) that explore successive visible displacements, the precise set-up varies between studies and makes comparisons near impossible. It is therefore difficult to compare species with regards to the A-not-B error until a standard test with a defined number of repetitions and movements between targets is implemented
Similarities between 2D and 3D convection for large Prandtl number
No full textUsing direct numerical simulations of Rayleigh-B\'enard convection (RBC), we perform a comparative study of the spectra and fluxes of energy and entropy for large and infinite Prandtl numbers in two (2D) and three (3D) dimensions. We observe close similarities between the 2D and 3D RBC, in particular the kinetic energy spectrum , and the entropy spectrum exhibits a dual branch with a dominant spectrum. We showed that the dominant Fourier modes in the 2D and 3D flows are very close
Analytical and diagnostic validation of a flow cytometric strategy to quantify blood and marrow infiltration in dogs with large b-cell lymphoma
No full textBackground Lymph node (LN), peripheral blood (PB) and bone marrow (BM) samples are commonly analyzed by flow cytometry (FC) for the immunophenotyping and staging of canine lymphomas. A prognostic value for flow cytometric BM infiltration in dogs with large B-cell lymphoma (LBCL) was demonstrated. Aim of the present study was to define the analytical performances of this technique, and to establish a cutoff suitable to safely discriminate between infiltrated and non-infiltrated PB and BM samples. Methods Large B-cells were added to control PB and BM samples, to achieve twelve different large B-cells concentrations, ranging from 0% to 50%. The percentage of large B-cells was recorded for each dilution, using a BD Accuri C6 flow cytometer. Accuracy was evaluated by Passing-Bablok regression analysis. Intra-assay precision was assessed at 0%, 1%, 3% and 10% dilutions evaluating the CVs of ten repeated acquisitions. ROC curves were drawn to identify the cutoffs most suitable to discriminate between 25 infiltrated (PARR-positive) and 25 non-infiltrated (PARR-negative) PB and BM samples, respectively. Results Optimal analytical accuracy and precision were achieved. Almost all CVs were <10%. Negative controls had up to 0.5% large B-cells, with 50% and 22% CV in PB and BM samples, respectively. 0.56% and 2.45% cutoffs were selected based on the ROC curves for PB and BM samples, respectively. Conclusions Quantification of large B-cells in PB and BM samples by FC is reliable and analytical performances met the acceptance criteria. Assessment of performances of different instruments and protocols is warranted. This article is protected by copyright. All rights reserved
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
