Relationship between behavioral marital therapy outcome and process variables.

This study was conducted to identify therapist and client behaviors with a positive response to social learning-based behavioral marital therapy. A sample of 32 couples receiving treatment was examined. Immediately after each therapy session, the therapist, husband, and wife independently completed process ratings forms that measured therapist and client behaviors during the session. Composite scales, derived from these ratings, were entered into multiple regression equations to examine their relationship with posttherapy marital satisfaction. After controlling for pretherapy marital satisfaction and the other predictor variables, therapists', husbands', and wives' ratings of positive client behavior (i.e., collaboration, active participation, and homework compliance) were positively associated with therapy outcome. Implications for marital therapy and suggestions for future research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Teachers' perceptions of students' reading abilities: An examination of the relationship between teachers' judgments and students' performance across a continuum of rating methods.

Teacher perceptions about students' academic abilities are important for several reasons (e.g., instructional decision making, special education entitlement decisions). Not surprisingly, researchers have investigated the accuracy of teachers' decisions. Although some data reveal that teachers are relatively good judges of academic performance, other findings have suggested otherwise. A likely explanation for conflicting findings is the varying assessment methods (e.g., direct vs. indirect, norm-referenced vs. peer-independent) and different data analysis procedures that have been used across studies. The purpose of this study was to investigate a continuum of teacher-perception assessment methods as they corresponded to students' oral reading fluency performance. Participants included 10 teachers and 87 first, second, and third grade students from a suburban school in the northeast. Overall results suggested that teachers were generally accurate when estimating students' performance when students had strong oral reading fluency skills, but teachers had more difficulty judging students with average to low oral reading fluency. Further, data interpretation of teachers' judgment accuracy differed somewhat depending upon the statistical method employed. Implications, limitations, and suggestions for future research related to this study are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Simulation of Circuit of Autodyne Sensor with Field-Controlled Transistor

The autodyne sensor operation modelling was carried out. Authors took into account frequency dependence of the field transistor parameters. The shape and a spectrum of generated oscillations in control points of the autodyne sensor circuit were researched, depending on position of an operating point of the transistor. It is revealed, that a condition of the least distortion of the generated oscillations shape is position of a working point of the transistor in the region of camber of its transfer characteristic. Modelling was carried out with Micro-Cap application

Peripheral inflammation undermines the plasticity of the isolated spinal cord.

Peripheral capsaicin treatment induces molecular changes that sensitize the responses of nociceptive neurons in the spinal dorsal horn. The current studies demonstrate that capsaicin also undermines the adaptive plasticity of the spinal cord, rendering the system incapable of learning a simple instrumental task. In these studies, male rats are transected at the second thoracic vertebra and are tested 24 to 48 hours later. During testing, subjects receive shock to one hindleg when it is extended (controllable stimulation). Rats quickly learn to maintain the leg in a flexed position. Rats that have been injected with capsaicin (1% or 3%) in the hindpaw fail to learn, even when tested on the leg contralateral to the injection. This learning deficit lasts at least 24 hours. Interestingly, training with controllable electrical stimulation prior to capsaicin administration protects the spinal cord against the maladaptive effects. Rats pretrained with controllable stimulation do not display a learning deficit or tactile allodynia. Moreover, controllable stimulation, combined with naltrexone, reverses the capsaicin-induced deficit. These data suggest that peripheral inflammation, accompanying spinal cord injuries, might have an adverse effect on recovery. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Cognitive–behavioral therapy to reduce weight concerns improves smoking cessation outcome in weight-concerned women.

Women smokers concerned about weight gain (N?=?219) were randomly assigned to 1 of 3 adjunct treatments accompanying group smoking cessation counseling: (a) behavioral weight control to prevent weight gain (weight control); (b) cognitive–behavioral therapy (CBT) to directly reduce weight concern, in which dieting was discouraged; and (c) standard counseling alone (standard), in which weight gain was not explicitly addressed. Ten sessions were conducted over 7 weeks, and no medication was provided. Continuous abstinence was significantly higher at posttreatment and at 6 and 12 months of follow-up for CBT (56%, 28%, and 21%, respectively), but not for weight control (44%, 18%, and 13%, respectively), relative to standard (31%, 12%, and 9%, respectively). However, weight control, and to a lesser extent CBT, was associated with attenuation of negative mood after quitting. Prequit body mass index, but not change in weight or in weight concerns postquit, predicted cessation outcome at 1 year. In sum, CBT to reduce weight concerns, but not behavioral weight control counseling to prevent weight gain, improves smoking cessation outcome in weight-concerned women.

Green function for a layer with rigidly fixed bases

The Green function for a layer with rigidly fixed bases is constructed by using the two-dimensional Fourier integral transformation. The singular part is presented in the closed form. The terms taking into account the influence of the boundaries of the layer are presented in the form of improper integrals of exponentially decreasing functions. The numerical analysis is performed for one component of the Green matrix under the action of a concentrated force at a point of the layer noncentral across the thickness. __________ Translated from Fizyko-Khimichna Mekhanika Materialiv, Vol. 44, No. 4, pp. 39–42, July–August, 2008.     

The Symbiotic Sustainability Model: Conceptualizing NGO–Corporate Alliance Communication

We introduce the Symbiotic Sustainability Model (SSM) as a macrolevel explanation of nongovernmental organization (NGO)–corporate alliances. The SSM presents NGO–corporate alliances as distinct interorganizational communication relationships, symbolized to stakeholders to influence the mobilization of capital. We contend that alliance partners communicatively co‐construct the alliance with stakeholders in order to mobilize economic, social, cultural, and political capital. By focusing on the communication of alliances' existence and character, new propositions emerge concerning the role of communication, capital mobilization resulting from NGO–corporate alliances, NGOs and corporations' choice(s) of alliance partner(s), the number of partners with whom organizations are likely to communicate, and potential risks and rewards. The model is illustrated using the Rainforest Alliance and Chiquita Better Banana program as an abbreviated case study.
