The Discriminating Properties of an Optoelectronic Movement Analysis Method in Patients With Parkinsonism

Several partly overlapping diseases have Parkinsonism as a symptom and tools that may differentiate between these disorders would be helpful. The authors evaluated the discriminating properties of the objective automated posturo-locomotor-manual (PLM) L-DOPA test in regard to health, and the movement disorders Parkinson's disease (PD), multiple system atrophy (MSA), and progressive supranuclear palsy (PSP). A PLM test–retest procedure was performed in healthy controls (n = 37) and results were compared with PLM L-DOPA tests performed by 132 patients with Parkinsonism in intermediate to advanced stages (56 PD, 53 MSA, 23 PSP). The movement time (MT) for the standardized movement and its different components was measured. The discriminating abilities of individual, or combinations of, test variables were determined by forward stepwise multiple logistic regression and evaluated with receiver-operating characteristic (ROC) analysis. Each PLM variable separated healthy persons from patients with Parkinsonism before administration of L-DOPA (area under the curve (AUC) = 0.94–0.99, p <.001 for any separate variable). A combination of (MT_off – MT_on)/MT_off and MT_on had the highest ability to separate patients with PD from patients with atypical Parkinsonism (area under the curve = 0.91, p <.001). The PLM test discriminates between healthy controls and patients with Parkinsonism, and between patients with Parkinson's disease and patients with atypical Parkinsonism.

Models as icons: modeling models in the semiotic framework of Peirce’s theory of signs

In this paper, we try to shed light on the ontological puzzle pertaining to models and to contribute to a better understanding of what models are. Our suggestion is that models should be regarded as a specific kind of signs according to the sign theory put forward by Charles S. Peirce, and, more precisely, as icons, i.e. as signs which are characterized by a similarity relation between sign (model) and object (original). We argue for this (1) by analyzing from a semiotic point of view the representational relation which is characteristic of models. We then corroborate our hypothesis (2) by discussing the conceptual differences between icons, i.e. models, and indexical and symbolic signs and (3) by putting forward a general classification of all icons into three functional subclasses (images, diagrams, and metaphors). Subsequently, we (4) integratively refine our results by resorting to two influential and, as can be shown, complementary philosophy of science approaches to models. This yields the following result: models are determined by a semiotic structure in which a subject intentionally uses an object, i.e. the model, as a sign for another object, i.e. the original, in the context of a chosen theory or language in order to attain a specific end by instituting a representational relation in which the syntactic structure of the model, i.e. its attributes and relations, represents by way of a mapping the properties of the original, which hence are regarded as similar in a relevant manner.     

The so-called rule of abstinence revisited

The paper discusses whether the rule of abstinence is still valid in the contemporary theoretical arena of psychoanalysis. Not only is this a debate on principle. It also raises the question of how gratifying the analyst should be in the analytic encounter, still remaining within the psychoanalytic paradigm. Current criticisms of the concept of abstinence are reviewed. The author replies to the objections. He argues that the so-called rule of abstinence is not a “rule” which describes the particular behaviour of the analyst, but a general principle describing the essence of the psychoanalytic cure. In the opinion of the author, abandoning this principle may have detrimental consequences both theoretically and technically. Finally, the author discusses the emotional presence of the analyst in the analytic setting and suggests an updated version of the idea of analytic abstinence.     

In-group ratings are affected by who asks and how: interactive effects of experimenter group-membership and response format

In three experiments, participants rated how well a number of adjectives described their in-group (e.g. kind-hearted, helpful, intelligent, efficient, etc.). In Experiment 1, females were found to rate their ingroup (females) more favorably when reporting verbally to female (rather than male) experimenters. This finding was further explored in two subsequent experiments where response format (written vs. verbal) was also manipulated. Both experiments revealed an interaction such that ethnic Swedes rated their in-group (Swedes) the most favorably when reporting verbally to an in-group experimenter and the least favorably when reporting verbally to a Middle Eastern experimenter. Results are discussed in relation to correction and contextual activation of social norms.     

Promoting positive parenting practices in primary pare: outcomes and mechanisms of change in a randomized controlled risk reduction trial

The aim of the present study was to evaluate whether a short parent-training program (PT) reduces risk factors related to development of childhood socio-emotional and behavior problems in a non-clinical community sample. Data were obtained from parents in a randomized controlled trial (RCT) on PT for children aged 2 to 8 years (N=186) at pre-intervention, post-intervention and one-year-follow up. There were significant differences in the changes in the two groups, with reductions in harsh parenting and child behavior problems, an enhancement of positive parenting and of the parents' sense of competence in the intervention group. The effects on parenting and parents' satisfaction all lasted through one-year follow up. Our findings suggests that a shortened version of a well-structured parenting intervention, The Incredible Years program, implemented in primary care at community level, reduces harsh parenting and strengthens positive parenting and parents' sense of competence, as reported by the parents. Issues related to a public health approach to promote positive parenting are discussed.     

A randomized controlled trial of mother–infant psychoanalytic treatment: II. Predictive and moderating influences of qualitative patient factors

A randomized control trial was performed on 75 dyads in Stockholm, Sweden, with infants under 1½ years. It recruited mothers who worried about the babies, themselves as mothers, and/or the mother–baby relationship. Two groups of mother–infant dyads were compared. One received only Child Health Centre care (the “CHCC” group) while the other received mother–infant psychoanalytic treatment plus CHCC (the “MIP” group). Significant treatment effects were found on mother‐reported depression, interviewer‐rated dyadic relationship qualities and externally rated maternal sensitivity, and near‐significant effects on mother‐reported stress, all in favor of MIP. The objective of this study is to investigate the predictive and moderating influences on outcomes by qualitatively assessed maternal and infant characteristics. The qualitative factors covered maternal suitability for psychoanalysis, and “ideal types” of mother and child, respectively. Outcome measures from two interviews with a 6‐month interval were depression (Edinburgh Postnatal Depression Scale (J. Cox, J. Holden, & R. Sagovsky, 1987 ), stress (Swedish Parental Stress Questionnaire (M. Östberg, B. Hagekull, & S. Wettergren, 1997 ), distress (Swedish Symptom Checklist‐90 (SCL‐90; L.R. Derogatis, 1994 ; M. Fridell, Z. Cesarec, M. Johansson, & S. Malling Thorsen, 2002 ) and infant social and emotional functioning (Ages and Stages Questionnaire: Social–Emotional (J. Squires, D. Bricker, K. Heo, & E. Twombly, 2002 ), relationship qualities (Parent–Infant Global Assessment Scale (PIR‐GAS; ZERO TO THREE, 2005), and videotaped interactions (Emotional Availability Scales, Z. Biringen, J.L. Robinson, & R.N. Emde, 1998 ). Suitability for psychoanalysis predicted outcome only on the PIR‐GAS. Two overarching maternal ideal types were created, reflecting their attitude to the psychoanalytic process: “Participators” and “Abandoned.” The Participators benefited more from MIP than they did from CHCC on maternal interactive sensitivity. A contrasting, but nonsignificant, pattern was found among the Abandoned mothers. Two ideal types of babies emerged: those “Affected” and “Unaffected” by the disturbance, respectively. Among Affected babies, dyadic relationships and sensitivity among their mothers improved significantly more from MIP than they did from CHCC. The superior effects of MIP applied especially to Participator mothers and Affected infants. For Abandoned mothers and Unaffected infants, CHCC seemed to be of equal value.     

Do military decision makers behave as predicted by prospect theory?

Four experiments were conducted to explore the robustness of risky choice framing among military decision makers. In the first experiment the original version of the Asian disease problem was administered. In contrast to Tversky and Kahneman's ( 1981 ) original findings, military decision makers were not influenced by the gain and loss framing. They demonstrated risk‐seeking behavior in both domains. In the second experiment, we administered a military version of the Asian disease problem. We found a significant framing effect, but it was unidirectional: The decision makers were risk seeking in both domains, but significantly more risk seeking in the loss domain. To explore the strength of this risk‐seeking preference, we altered the problem in a third experiment, making the risky alternative 12.5% less attractive than the certain one. Again, we found risk‐seeking behavior in both domains. Finally, we explored reasons for these deviations from prospect theory by comparing the responses of business students and military officers. In this analysis, we observed significantly higher levels of self‐efficacy in the military sample, as compared to the civil sample, and that the self‐efficacy influenced risk seeking only in the military sample. In a post hoc analysis we also found that years of education reduced risk‐seeking preference. Implications and directions for future research are discussed.

Religious revivalism in nineteenth-century Norway and twentieth-century Egypt: A critique of fundamentalism studies

The aim of this article is to challenge the idea that the current Islamist movements could fruitfully be considered to belong to a global category of fundamentalism. For this purpose it is necessary to criticize the most sophisticated attempts that have been made to argue for the existence of such a general phenomenon, with Islamism as one of its most prominent constituent parts.
