The link between schizophrenia and anomalies in the distal upper limb is well documented. Preliminary studies have identified a number of biometric parameters of the hand by which schizophrenics can be distinguished from matched controls. The current study seeks to determine whether patients with schizophrenia can be singled out from a disparate group of other mental disorders by using the same parameters. We studied three groups, totaling 134 men: 51 diagnosed with schizophrenia, 29 with anxiety and mood disorders, and 54 comprising a control group. Seven parameters were studied: the proximal interphalangeal joint, the eponychia of the middle and ring digits, two dermatoglyphic features, and two constitutional factors. Examiners evaluated the parameters based on photographs and prints. An initial Mann Whitney comparison showed no significant difference between the control group and those identified with anxiety and mood disorders. We therefore accounted for them as a single group. In a discriminant analysis, an overall accuracy of 78.4% was established with a sensitivity of 80.4% (schizophrenics identified correctly) and a specificity of 77.1% (controls identified correctly). These results suggest that the biometric parameters employed may be useful in identifying patients with schizophrenia from a disparate group of other mental disorders.

Objective: We examined whether the type of brain injury impacts the psychopathological profile and quality of life in children with cerebral palsy (CP). Methods: We assessed 18 children with CP [9 premature, 9 asphyxia at term] and 16 siblings using parent forms of the child behavior checklist (CBCL), disruptive behavior disorder rating scale (DBDRS), and pediatric quality of life inventory (PEDSQL). Results: Children with CP demonstrated more emotional and behavioral symptoms (depression, anxiety, and social, thought, and attention problems) and lower quality of life than their siblings. The pathopsychological profile of children with CP due to prematurity and asphyxia was similar. Conclusion: Etiology does not impact the psychopathology in children with CP.

This paper formalizes theoretical and empirical analyses of the determination of union membership. It is argued that an important (and usually ignored) consideration affecting the union status of workers is the externalities between (potential) union members: The gain a worker derives from unionization is affected by the characteristics of the workers who already belong to the union, and the gain union members derive from admitting an additional worker to membership depends on that worker’s characteristics. Thus, two conditions must hold if a worker is to join a union: (1) unionization should increase his wage, and (2) union members must benefit from adding him. The main implication of this analysis is that in a given industry/occupation a union is more likely to form among workers withlower rents. To test this proposition, I present an empirical analysis using data from the May 1979 Current Population Survey (CPS) Public Use Sample. A procedure for measuring worker’s rent is discussed and certain relationships between rent and union membership are identified.

Wage negotiation is modeled as an oceanic game. The employer and unions (if any) are atomic players, interacting with an 'ocean' of infinitesimal individual, unorganized workers. All workers are equally productive inside the firm, but may differ in their outside opportunities. The 'worth' of a coalition is its achievable surplus, and the Shapley value of the c -f game thereby defined provides a plausible, equitable wage settlement. Several different levels of unionization are investigated. It is noteworthy that this approach does not introduce specific bargaining procedures; instead (like the core) it builds on cooperative possibilities present in the economic situation itself.

Since abnormalities in distal upper limb development are among the minor physical anomalies associated with schizophrenia we attempted to determine whether patients with schizophrenia can be identified on the basis of specific morphologic and dermatoglyphic features of the hand. Photographs and prints of the hands of 38 patients with schizophrenia and those of 42 control subjects were evaluated and graded on 13 biometric parameters. Results were statistically evaluated. A combination of three of the parameters was found to have good predicting abilities to distinguish between schizophrenics and controls. Subjects having high values in these three parameters were found to have a higher propensity to be defined as schizophrenics. In order to define a simple rule for classifying subjects we chose a criterion of having a value of 3 (in a scale from 1 to 3) in at least one of these three discriminating variables. This rule yielded an overall accuracy of 81.2%. Among controls, 85.7% of subjects did not fulfill such criteria, while 14.3% were defined as false positives. Among schizophrenics 76.3% achieved this condition while 23.7% were false negatives. The technique's objectivity and ease of application could facilitate the diagnosis of this disease.
