Fifteen years of cutaneous and mucocutaneous leishmaniasis in Bolivia: a retrospective study

The photosensitizing properties of p-nitroacetophenone (PNAP), a well-known radiosensitizer, have been studied in near UV region. The mechanism of PNAP photosensitization has been investigated by testing the efficiency of singlet oxygen production using photooxidation of 2,2,6,6-tetramethylpiperidine (TEMP) and photodegradation of guanosine. In both the cases, the enhancement effect of deuterated solvents has been observed. Results of these experiments suggest the significant role of type II mechanisms in PNAP photosensitization.     

"Cadism": Odd man out.

Comments that L. B. Silverstein's (see record 1992-05293-001) article on child care and maternal employment contributes unfounded and damaging misbeliefs regarding fathers. The dad-as-cad myth suggests intentional malevolence or at least blatant failure by fathers to care for others, and suggests that their failure to share equally in child care and household management is the primary cause of marital conflict. W. B. Johnson and D. Hayes propose a research agenda for fathering that originates in a coherent model of male development in the context of ever-changing environmental demands.

Adolescents in stepfamilies: Developmental family interventions.

Discusses issues and interventions for working with adolescents who live in stepfamilies. A developmental perspective, using psychoeducation and brief strategic intervention approaches, is proposed for working with stepfamilies. Six major issues for adolescents in stepfamilies are discussed: developmental issues, sexuality issues, parent–child relationships, parenting in stepfamilies, nonresidential parent–child issues, and changes in visitation and custody. Case illustrations and suggested interventions are presented for each of these areas. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Palliative treatments of cancers of upper respiratory and digestive tracts

Palliative treatment of head and neck cancers needs an initial evaluation based upon clinical symptoms and tumoral behaviour. Local recurrences are the most frequent presentation of tumoral failures. The therapeutic management of these local recurrences requires a mixture of unspecific and specific oncologic procedures. Radiotherapy and chemotherapy are frequently used in those circumstances in order to reduce the tumoral volume and to facilitate the effectiveness of unspecific treatments. Management of metastatic disease is often impaired by the moderate efficiency of chemotherapy while this treatment leads to marked side effects. Basically, the best therapeutic choice depends on the expected positive balance between the improvement of symptoms and the level of treatment-related side effects. However, daily clinical approach is a better way to care these patients than predefined rigid protocols.     

Are IQ scores valid for children who are poor readers?

Remedial services for children with reading problems are often allocated according to discrepancies between reading and IQ scores. Results of some recent research suggest, however, that IQ scores of poor readers do not covary with their levels of functioning in other cognitive domains. This study evaluated whether the external validity of IQ scores (from the Wechsler Intelligence Scale for Children—Revised [WAIS—R]) was moderated by reading levels within 2 separate samples of a total of 382 referred children (aged 7–16 yrs). It was found that IQ scores had expected correlations with external measures of verbal, visual-spatial, short-term memory, and arithmetic ability, and that these relations were invariant across levels of reading skill.

Ghosts, taxonomies, and social psychology.

This article critically analyzes social psychology's assumption that psychological states can explain social behavior. On the basis of an analysis of the logic of classification systems, the author argues that there are no procedures available to independently verify the existence of these psychological states. As a consequence, explanations of social behavior are subject to continual challenge and replacement. Furthermore, it is argued that focusing on psychological states serves to inhibit the systematic study of societal changes (particularly changes in technology) that are affecting and shaping all aspects of human existence. This article describes an alternate paradigm that coordinates one dimension of societal events—technology—with changes in people's consciousness and subsequent behavior. A taxonomy of technology is described in the closing section of the article. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Randomization in individual choice behavior.

There is ample evidence that people cannot generate random series when instructed to do so. Rather, they produce sequences with too few symmetries and long runs and too many alternations among events. The authors propose a psychological theory to account for these findings, which assumes that subjects generate nonrandom sequences that locally represent theoretical random series subject to a constraint on their short-term memory. Closed-form expressions are then derived for the major statistics that have been used to test for deviations from randomness. Results from 3 experiments with 2 and 3 equiprobable alternatives support the model on both the individual and group levels. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
