Applying bibliometric mapping in a high level science policy context

Bibliometric maps have the potential to become useful tools for science policy issues. The complexity of the structures, however, makes it often very difficult to interpret the results. In this study, we present a case study in which we use the bibliometric mapping results to address a high level science policy issue of research efficiency. By revealing the results in an alternative way, we increased the utility of bibliometric mapping within the science policy context. Moreover, by including additional information to the entities in the landscape, we provide useful input for the research potential.     

Predicting post-treatment-initiation alcohol use among patients with severe mental illness and alcohol use disorders.

Few investigators studying alcohol abuse among individuals with a severe mental illness (SMI) have examined predictors of posttreatment alcohol outcomes. In the present study, a multivariate approach based on a theoretical model was used to study the relationship between psychosocial factors and post-treatment-initiation alcohol use. Predictors of alcohol use outcomes were examined in 278 individuals diagnosed with a current schizophrenia-spectrum or bipolar disorder and an alcohol use disorder (AUD). At 6-months follow-up, 144 of 228 available participants (63%) had good clinical outcomes. The results of structural equation modeling indicated that type of pretreatment residential setting was directly related to treatment, with participants who lived in supervised settings (41%) reporting significantly more days of treatment (β = .34, p     

Perceived shrinkage of motion paths.

We show that human observers strongly underestimate a linear or circular trajectory that a luminous spot follows in the dark. At slow speeds, observers are relatively accurate, but, as the speed increases, the size of the path is progressively underestimated, by up to 35%. The underestimation imposes little memory load and does not require tracking of the trajectory. Most importantly, we found that underestimation occurred only when successive motion vectors changed in direction. This suggests a perceptual rather than representational origin of the illusion, related to vector-sum integration over time of neural motion signals in different directions.

Evaluation of the laboratory prediction of surface properties of bituminous mixtures

An experimental and analytical investigation was carried out both in laboratory and in situ on wearing courses. The approach presented in this paper aims to predict the in situ density and surface properties of bituminous layers, during the phase of mix design in laboratory. Therefore, the main attempt of this study is to identify, amongst the commonly available laboratory equipments, the most adequate for producing specimens that, used for carrying out simple and reliable laboratory test, allow the prediction of the surface characteristics of the mixture as laid on site.This is done by comparing the data collected from an experimental site with those calculated from laboratory specimens compacted with the superpave gyratory compactor (SGC).Typical laboratory tests (such as the sand patch method and the skid test) as well as the surface data obtained with a laser profilometer have been considered for characterizing the properties of a standard Italian wearing course, laid in two different final thicknesses and produced with the most common raw materials, according to the currently used techniques for mixtures production and laying process for maintenance work. An evaluation of the SGC ability to represent the density and surface properties of the mixture once on site is then discussed.     

Preferences of therapists-in-training for client characteristics.

The preferences of 132 therapists-in-training for 16 client characteristics were investigated using a paired comparison methodology. Therapists most preferred to work with clients who were psychologically minded, shared similar attitudes and values, and had dissimilar personally troubling problems. They least preferred to work with clients who were not psychologically minded, had dissimilar attitudes and values, and were older. Order of preferences was not influenced by therapist sex, race, clinical experience, socioeconomic status, sexual orientation, or theoretical orientation. Limitations of this study as well as implications for further research and training are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Tagged Systems: A Framework for the Specification of History-dependent Properties

We propose a general method for the treatment of history-dependent runtime errors. When one has to control this kind of errors, a tagged version of the language is usually defined, in which tags capture only the necessary information of the history of processes. We will characterize such tagged languages as being quotients of the reachability tree defined by the computations of the original language. From this fact we can conclude that the property characterized by each tagged language is indeed a property of the original one. In this way, we can work in a common framework, instead of defining an ad hoc semantics for each property. In particular, we could still use the analysis machinery existing in the calculus in order to prove that or other related properties. We have applied this methodology to the study of resource access control in a distributed π-calculus, called Dπ. In particular, we have proved that the tagged version of Dπ is indeed a tagging according to our definition.     

Development of a system for categorizing client reactions to therapist interventions.

We developed a measure of client reactions to therapist interventions. The 21 categories of the measure were divided into 14 positive and 7 negative reactions, which differed significantly from each other on client helpfulness ratings. Preliminary validity data indicated that therapist intentions were related to client reactions more for successful cases than unsuccessful cases, pretreatment symptomatology was highly predictive of which reactions the clients reported, there were some predictable changes in reactions across time in treatment, and within-case correlations of reactions with client-rated session depth and smoothness indicated some similarities across cases. We discuss the case-specific nature of client reactions, methodological issues, and the need for greater therapist awareness of client reactions.

Therapist perspectives on countertransference: Qualitative data in search of a theory.

A consensual qualitative research strategy was used to examine data from 127 interviews conducted with 8 psychologists immediately following their sessions of brief therapy with 8 clients. Analyses revealed 3 domains relevant to countertransference: origins (including categories of family issues, needs and values, therapy specific issues, and cultural issues), triggers (including categories of content of client material, therapist comparing client with others, change in therapy structure or procedures, therapist assessing progress of therapy, therapist perception of client, and emotions), and manifestations (including categories of approach, avoidance, negative feelings, and treatment planning). The frequency of categories within and across cases was classified, and relationships among categories from the 3 domains were detected, generating hypotheses for future empirical research. Implications for practice, training, and continued research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Therapist retrospective recall impasses in long-term psychotherapy: A qualitative analysis.

Twelve experienced therapists completed a questionnaire, and 8 of the 12 were then interviewed about their experiences with a therapeutic impasse that ended in the termination of therapy. Data were analyzed using a qualitative methodology. Results indicated that most of the clients were anxious and depressed with personality disorders and interpersonal problems. Therapists perceived impasses as having a profound negative impact on both clients and therapists. Variables associated with impasses in a majority of the cases were a client history of interpersonal problems, a lack of agreement between therapists and clients about the tasks and goals of therapy, interference in the therapy by others, transference, possible therapist mistakes, and therapist personal issues. Implications for training, practice, and research are provided. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
