Integrating the SWAP and Rorschach composite measures for exploring psychopathological patterns of mental functioning
No full textThis study addressed the exploration of a multimethod psychodynamic assessment and its relation to psychopathological patterns. The study applies the Shedler-Westen Assessment Procedure (SWAP; Shedler, J., & Westen, D., 2006, Personality diagnosis with Shedler-Westen Assessment Procedure (SWAP): Bridging the gulf between science and practice. In P. D. M. Task Force (Ed.), Psychodynamic Diagnostic Manual (pp. 573–613). Silver Spring, MD: Alliance of Psychoanalytic Organizations.) and three composite Rorschach measures to a sample of 72 outpatients with various Diagnostic and Statistical Manual of Mental Disorders Axis I diagnoses (American Psychiatric Association, 2000, Diagnostic and Statistical Manual of Mental Disorders (DSM–IV–TR).

E., & Weinberger, Y., 2005. Using the Rorschach for exploring the concept of transitional space within the political context of the Middle East.

Consistent with the literature, in this study, the multimethod assessment revealed modest unilinear associations, if any, between each of the Rorschach indices and the SWAP scales. However, regression analyses showed that the joint use of the EII-2 and the RFS-P explained a substantial portion of the variance in the SWAP scales that indicate inhibition and avoidance (obsessive personality disorder score and Avoidant Q factor, respectively). Furthermore, when used with the RFS-S, the EII-2 was able to significantly explain variance in the SWAP scales that indicate interpersonal detachment (schizotypal personality disorder score and Schizoid Q factor). The implications of these results for clinical practice will be discussed

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
Development of a dynamic population model as a decision support system for Codling Moth (Cydia pomonella L) management
No full textIn 2004 RIMpro-Cydia was developed as a dynamic population model that simulates the
within-year biology of a local codling moth population. The model is meant to be used by
growers and advisors to optimize the control of codling moth populations in organic and
integrated managed orchards. The model is based on literature data and unpublished
research data. Fractional boxcar trains are used to mimic the dispersion in the
developmental processes. The model is run in real time on the data input of local weather
stations, starting on 1 January. The output of the model was compared with the results of
field observations in three years in an untreated orchard. In the years 2005 to 2007 the
progress in egg deposition as predicted by the model was in general agreement with the
field data. The start of the egg deposition period was predicted well. The end of the egg
deposition period was predicted when in the field about 10% of the eggs was still to be
laid. There was no consistency in the relation between cumulated pheromone trap catches
and the cumulative egg deposition as calculated from the field data
VRCT: Randomized Controlled Trial Evaluating the Impact of Virtual Reality on behavioral and Psychological Symptoms and Quality of Life of Acute Care Inpatients with Dementia
No full textEvaluating the Impact of Virtual Reality on the Behavioral and Psychological Symptoms of Dementia and Quality of Life of Inpatients With Dementia in Acute Care: Randomized Controlled Trial (VRCT)
No full textBackground:
Virtual reality (VR) is increasingly considered a valuable therapeutic tool for people with dementia. However, rigorous studies are still needed to evaluate its impact on behavioral and psychological symptoms of dementia (BPSDs) and quality of life (QoL) across care settings.
Objective:
The primary aim of this study was to evaluate the impact of VR therapy on managing BPSDs, falls, length of stay, and QoL in inpatients with dementia admitted to an acute care hospital. The secondary aim was to evaluate the intervention’s feasibility in terms of acceptability, safety, and patient experience.
Methods:
A prospective, open-label, mixed methods, randomized controlled clinical trial was conducted between April 2019 and March 2020. A total of 69 participants (aged ≥65 years with a diagnosis of dementia and who did not meet the exclusion criteria) were randomly assigned to either the control (n=35, 51%) or VR (n=34, 49%) arm. Participants in the experimental (VR) arm were visited by a researcher and watched 360° VR films on a head-mounted display for up to 20 minutes every 1 to 3 days, whereas individuals in the control arm received standard of care. Instances of daily BPSDs and falls were collected from nurses’ daily notes. QoL was measured through semistructured interviews and the Quality of Life in Late-Stage Dementia scale. Structured observations and semistructured interviews were used to measure treatment feasibility. The primary outcomes were analyzed at a 95% significance level based on the intention-to-treat method.
Results:
VR therapy had a statistically significant effect on reducing aggressiveness (ie, physical aggression and loud vociferation; P=.01). Substantial impact of VR therapy was not found for other BPSDs (eg, apathy), falls, length of stay, or QoL as measured using the Quality of Life in Late-Stage Dementia scale. The average VR therapy session lasted 6.8 (SD 6.6; range 0-20) minutes, and the intervention was overall an acceptable and enjoyable experience for participants. No adverse events occurred as a result of VR therapy.
Conclusions:
Immersive VR therapy appears to have an effect on aggressive behaviors in patients with dementia in acute care. Although the randomized controlled trial was stopped before reaching the intended sample size owing to COVID-19 restrictions, trends in the results are promising. We suggest conducting future trials with larger samples and, in some cases, more sensitive data collection instruments.

Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
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
Equilibrium reconstruction in an iron core tokamak using a deterministic magnetisation model
No full textIn many tokamaks ferromagnetic material, usually referred to as an iron-core, is present in order to improve the magnetic coupling between the solenoid and the plasma. The presence of the iron core in proximity to the plasma changes the magnetic topology with consequent effects on the magnetic field structure and the plasma boundary. This paper considers the problem of obtaining the free-boundary plasma equilibrium solution in the presence of ferromagnetic material based on measured constraints. The current approach employs, a model described by O'Brien et al. (1992) in which the magnetisation currents at the iron-air boundary are represented by a set of free parameters and appropriate boundary conditions are enforced via a set of quasi-measurements on the material boundary. This can lead to the possibility of overfitting the data and hiding underlying issues with the measured signals. Although the model typically achieves good fits to measured magnetic signals there are significant discrepancies in the inferred magnetic topology compared with other plasma diagnostic measurements that are independent of the magnetic field. An alternative approach for equilibrium reconstruction in iron-core tokamaks, termed the deterministic magnetisation model is developed and implemented in EFIT++. The iron is represented by a boundary current with the gradients in the magnetisation dipole state generating macroscopic internal magnetisation currents. A model for the boundary magnetisation currents at the iron-air interface is developed using B-Splines enabling continuity to arbitrary order; internal magnetisation currents are allocated to triangulated regions within the iron, and a method to enable adaptive refinement is implemented. The deterministic model has been validated by comparing it with a synthetic 2-D electromagnetic model of JET. It is established that the maximum field discrepancy is less than 1.5 mT throughout the vacuum region enclosing the plasma. The discrepancies of simulated magnetic probe signals are accurate to within 1% for signals with absolute magnitude greater than 100 mT; in all other cases agreement is to within 1 mT. The effect of neglecting the internal magnetisation currents increases the maximum discrepancy in the vacuum region to >20 mT, resulting in errors of 5%-10% in the simulated probe signals. The fact that the previous model neglects the internal magnetisation currents (and also has additional free parameters when fitting the measured data) makes it unsuitable for analysing data in the absence of plasma current. The discrepancy of the poloidal magnetic flux within the vacuum vessel is to within 0.1 Wb. Finally the deterministic model is applied to an equilibrium force-balance solution of a JET discharge using experimental data. It is shown that the discrepancies of the outboard separatrix position, and the outer strike-point position inferred from Thomson Scattering and Infrared camera data are much improved beyond the routine equilibrium reconstruction, whereas the discrepancy of the inner strike-point position is similar.
