A Nonparametric,Multiple Imputation-Based Method for the Retrospective Integration of Data Sets

Complex research questions often cannot be addressed adequately with a single data set. One sensible alternative to the high cost and effort associated with the creation of large new data sets is to combine existing data sets containing variables related to the constructs of interest. The goal of the present research was to develop a flexible, broadly applicable approach to the integration of disparate data sets that is based on nonparametric multiple imputation and the collection of data from a convenient, de novo calibration sample. We demonstrate proof of concept for the approach by integrating three existing data sets containing items related to the extent of problematic alcohol use and associations with deviant peers. We discuss both necessary conditions for the approach to work well and potential strengths and weaknesses of the method compared to other data set integration approaches.     

Differential Reinforcement of Other Behavior in the Treatment of Inappropriate Behavior and Aggression in an Adult with Mental Retardation at a Vocational Center

Differential reinforcement of other behavior (DRO) was used to reduce aggression and other inappropriate actions in a 26-year-old man with moderate mental retardation employed at a vocational center. Initially high baseline levels of inappropriate behavior were reduced by implementing contingent praise and a sticker system used to earn points needed to gain access to social activities. The procedure was low cost, required minimal time and effort on the part of center staff, and made it possible for the client to remain employed at the vocational center.     

Information-Hierarchical Organization of Mankind and Problems of Its Sustainable Development

The information-hierarchical approach is used to analyze the evolutionary developed organization of mankind. This organization is shown to be hierarchical, from molecular hierarchical levels to the religious ones. Time cycles of each level operation are included in the greater cycle of the next level according to the specific schemes defined by the common information principle of natural system development. Time cycles of levels have duration of 1 second, 6 seconds, 42 seconds, 24 hours, 11 days, 1 years, 33 year, 1,000 years, 3,000 years or 6,000 years and all together make up the mankind clock that is similar to the formerly ascertained biosphere clock. The cycles of duration from 1 second to 33 years form the human biological clock, so the information-hierarchical organization of cell metabolism manifests itself as the key mechanism of the clock. The new scientific field has been characterized. It is the management of sustainable development of the states as evolutionary developed systems with the use of information relationships of their functioning. In the case of Christianity adoption by any large ethnos the next 1,000-year cycle of the Christianity-Judaism system will start.     

Using Interpreters in Mental Health Counseling: A Literature Review and Recommendations

Limited understanding of the challenges inherent in counselor‐interpreter collaboration may potentially result in inadequate or ineffective mental health services. To provide guidelines for effective mental health assistance of clients who are English language learners, the authors review the literature regarding the partnership between counselors and interpreters. Suggestions for collaborative practices, including pre‐ and postsession directives, are included. Una comprensión limitada de los desafíos inherentes a la colaboración entre consejero e intérprete podría dar como resultado un servicio de salud mental inadecuado o ineficaz. Con el propósito de ofrecer pautas para una asistencia eficaz a la salud mental de aquellos clientes que están aprendiendo inglés, los autores revisan la literatura sobre la asociación entre consejeros e intér‐pretes. Se incluyen sugerencias para prácticas de colaboración, incluyendo directivas para antes y después de las sesiones.     

The Mental Health Needs of Youth with Emotional and Behavioral Disabilities Placed in Special Education Programs in Urban Schools

We describe the psychosocial characteristics of youth with an average age of 11.8 years served in special education due to emotional disturbances in urban communities (N = 158). Data were also collected describing service utilization, academic functioning, and family characteristics. Ten schools in three mid-size urban cities participated. Results from the administration of standardized assessments revealed that the majority of students scored in the clinical range on the parent version of the Child Behavior Checklist and the Columbia Impairment Scale, indicating significant levels of emotional and behavioral impairment. Further, behavior problems began at an early age with 80% of the youth using outpatient services beginning at the average age of 7.5 years and 29% of the youth using inpatient services beginning at an average age of 8.4 years of age. Most of the youths' school careers (67%) have been in a special education setting. The most common services currently being supplied by school personnel was individual counseling and this was provided for 63% of the students while child-serving agency personnel were providing individual counseling for 17% of the youth. Implications for the development of multi-agency collaborative services are presented.     

The backward masking red light effect in schizophrenia: relationship to clinical features and neurocognitive performance

The "backward masking red light effect" involves a change in visual backward masking performance with a red (compared with a green or gray) background that is in the opposite direction relative to nonpsychiatric controls. This effect has been previously reported in individuals with schizophrenia, their first-degree relatives, and a schizotypy sample. The current study provides the first examination of the relationship of this effect with clinical and neurocognitive measures in a new sample of higher functioning patients with schizophrenia. A location backward masking by pattern task was administered to 16 outpatients with schizophrenia and 21 nonpsychiatric controls. The task was presented on red, green, and gray backgrounds. There was a significant group by color interaction at the 60-ms stimulus onset asynchrony: Participants with schizophrenia tended to decrease accuracy with a red (compared with a gray) background, whereas controls tended to increase accuracy. This interaction remained significant after covarying for baseline (gray) backward masking accuracy. In the schizophrenia patients, a decrease in backward masking accuracy to the red background was correlated with more negative symptoms, lower estimated premorbid IQ, and greater color-word Stroop interference but was not related to positive or disorganized symptoms, age of onset, duration of illness, digit symbol coding performance, or baseline (gray) backward masking accuracy. In contrast, there was no relationship between the red light change score and any of the neurocognitive variables in the control group.     

Evaluating Merger and Intersection of Equivalence Classes with One Member in Common

Sidman (1994) noted that the existence of a member that is common to more than one class may produce either class merger (union) or class intersection. A multiple-selection, matching-to-sample test was developed to examine the conditions under which these outcomes occur. Test trials each required three conditional discriminations involving selection or rejection of comparison stimuli under control of samples representing two categories. Test results obtained from an initial group of typical adults using familiar stimuli (DOG and BIRD, pictures of dogs and birds and relevant printed breed names (e.g., DALMATIAN, RETRIEVER) showed the conditional stimulus control best described as intersection. For example, the word DALMATIAN provided the context for selecting the dalmatian but not the retriever picture. However, these results may have depended on the participants'' verbal history as English speakers. Would conditional-discrimination training with overlapping sets of laboratory-generated stimuli also result in intersection? Naïve typical adults were assigned to one of three different training conditions. Like the participants tested with familiar stimuli, these participants demonstrated highly reliable test outcomes best described as showing class intersection, regardless of training condition. These findings begin to elucidate the necessary and sufficient conditions for establishing complex category-like classes of stimuli.     

What did the early American presidents really look like? Gilbert Stuart portraits as a "Rosetta Stone" to the pre-photography era

The American painter Gilbert Stuart (1755 - 1828) painted many prominent individuals, including the first six presidents of the United States, and several of his later subjects were also photographed. We compared these photographs to Stuart's portraits of the same individuals and characterized the differences between Stuart's representations and his subjects' actual appearances. This allows us to create more photographic likenesses of other Stuart subjects, including individuals who lived before the invention of photography.     

Power fosters context-independent, analytic cognition

The present research tested the hypothesis that power, defined as the capacity to influence others, promotes analytic cognitive processing, by examining the use of linguistic categories and the categorization of objects. Supporting the hypothesis, recalling instances of influencing others facilitated the use of adjectives and discouraged the use of verbs to describe others (Study 1). Recalling instances of influencing others also promoted taxonomic, instead of thematic, categorization (Study 2). Furthermore, the authors also examined the effect of power in a real-life context. They examined whether socioeconomic status (SES) differences in cognitive processing can be partly explained by sense of agency, an antecedent of power (Study 3); high SES individuals made more taxonomic categorization than did low SES individuals, and a sense of agency partially mediated the SES differences in categorization. These findings underscore the role of power in shaping cognitive processes.     

Social and hormonal bases of individual differences in the parental behaviour of birds and mammals.

We present an overview of research on how social experiences and hormonal responses affect individual variation in parental care of birds and mammals. The parental roles of prolactin and glucorticoids (corticosterone or cortisol) have many similarities in birds and in mammals. Prolactin may be involved in the initiation of parental interactions, with prolactin variation possibly explaining individual differences in parental decision-making. Glucocorticoid levels increase when parents have to work harder, with some individuals showing greater hormonal and behavioural responses than others. Testosterone interferes with paternal behaviour in birds, but its role is more complex and species-specific in male mammals. We examine these differences in an adaptive framework, where retaining flexibility of response has allowed individuals to respond differentially to social opportunities and environmental change.
