A multiple-sequence variant of the multiple-baseline design: A strategy for analysis of sequence effects and treatment comparison.

The design logic and potential uses of a variant of the multiple-baseline design that implements multiple treatment sequences is described. The multiple-baseline multiple-sequence (MBL-MS) consists of 2 or more multiple-baseline designs that are interlaced with one another and include all possible sequences of the treatments. The counterbalanced sequencing of treatments permits observation of any sequence effects that are present. This sequencing can permit identification of an optimal treatment sequence and comparison of relative efficacy of treatments. This variation of the multiple baseline also extends the available treatment comparison designs by providing an additional design that does not require reversal or treatment or sequence effects. Because of vulnerability to ceiling and floor effects, the MBL-MS design appears to be primarily useful for the comparison of treatments that take several sessions to produce an optimal level of responding or when the behavior is not subject to floor or ceiling effects.

Correlations of global and diffuse solar luminous efficacy for all sky conditions and comparisons with experimental data of five localities

Some simplified correlations of mean hourly global and diffuse luminous efficacy on the horizontal plane for all sky conditions have been obtained for Arcavacata di Rende (Italy) and have been compared with other literature models and other experimental data measured in Geneva (Switzerland), Vaulx-en-Velin (France), Bratislava (Slovakia) and Osaka (Japan). The comparisons show that, for global efficacy, the differences among the various models are not significant, and the use of a model with a constant value of efficacy gives good predictions of global illuminance. For the prediction of diffuse illuminance the differences among the models are larger, but the use of a constant diffuse efficacy provides a good first estimate of diffuse illuminance.     

Meta-analysis of HIV risk-reduction interventions within drug abuse treatment programs.

A meta-analysis was conducted on studies using a treatment-comparison group design to evaluate HIV/AIDS risk-reduction interventions for clients enrolled in drug abuse treatment programs. Overall, the interventions studied were found to have a reliable positive (weighted) effect size (d?=?0.31), and this was unlikely to be due to publication bias. Effect sizes for specific categories of outcome variables were 0.31 for knowledge, attitudes, and beliefs; 0.26 for sexual behavior; 0.62 for risk-reduction skills; and 0.04 for injection practices. A number of potential moderators were examined. Effect sizes were negatively correlated with the presence of predominantly ethnic minority samples and positively correlated with the number of intervention techniques used, the intensity of the intervention, intervention delivery at a later stage of drug treatment or within methadone treatment, and the presence of a number of specific intervention techniques.

A canonical correlation of fire protective behaviors and beliefs

The use of a multivariate procedure is demonstrated in the analysis of a survey of various firesafety actions and beliefs in a college student population. A canonical correlation analysis identified three significant factors and revealed that performing a safety inspection of one's residence for potential hazards was associated with beliefs in one's personal efficacy in handling fire situations, whereas engaging in more emergency-related actions such as checking to see if one's smoke detector was working properly, knowing the emergency telephone number, having it posted by the telephone, and knowing two exits out of each area of the home was related to beliefs of susceptibility and seriousness concerning fires. A third factor revealed an association between having a sprinkler system (but not a fire extinguisher) present in the place of residence, vacuuming the dust from a smoke detector, and having ever practiced an emergency escape with beliefs reflecting susceptibility to future (but not present) fire hazards, adequacy of firesafety knowledge, and beliefs in the effectiveness of firesafety inspections. It is shown that the results of this analysis can be quite useful in guiding the development of firesafety education materials; also, the need to differentiate the specific motivational approach depending upon the type of firesafety action being promoted with this particular population is revealed.

Model based evaluation of exterior daylight illuminance distribution

Energy conservation in buildings is greatly influenced by natural daylight in tropical region. A vital step towards development and promotion of daylighting technology in buildings is a prior study on estimation of exterior daylight availability for illuminating its interiors. In view of this, the present communication depicts the preliminary work progress carried out to arrive at a comprehensive idea on assessment of daylight availability and its characteristics. The study is reported taking the representative case of Bangalore (India) (latitude 12.97° N, longitude 77.56° E),which in future work facilitates to device suitable interior illuminance models and lighting controls for a daylight-artificial light integrated scheme. The objective of this paper is to document the estimation of spatial exterior daylight parameters like exterior horizontal as well as vertical global and diffuse daylight illuminance in addition to their respective luminous efficacies computed using an established analytical model. The paper also highlights user friendly computer simulation tool developed, for the detailed estimation of daylight availability at a particular region by the inclusion of corresponding solar radiation data.     

Collective efficacy: A neglected construct in the study of schools and student achievement.

A theoretical analysis is advanced that discusses social cognitive theory at the group level to explain the formation and impact of collective efficacy. The study used student- and school-level data from a sample of urban elementary schools. Consistent with social cognitive theory, mastery experience was found to be a significant predictor of differences between schools in teachers' collective efficacy perceptions. In addition, after controlling for student demographic characteristics and prior achievement, collective efficacy was positively and significantly related to differences among schools in student achievement. Finally, the amount of consensus among faculty members regarding collective efficacy perceptions was not a significant predictor of student achievement, nor was it significantly related to school socioeconomic status or minority concentration.
