The building recognition and analysis of remote sensing image based on depth belief network

The deep belief network model, which is widely used in deep learning, consists of a multi-layer constrained Boltzmann machine and a back-propagation network. The authors have conducted parameter sensitivity experiments on the number of iterations, the number of hidden layers and the number of hidden layer nodes in the DBN network for remote sensing image classification, and obtained a set of optimal parameter setting schemes. Moreover, the DBN algorithm has been enhanced with an improved Dropout strategy. The improved Dropout strategy selects only part of the data to clear the weight at a time, and a local area randomly clear strategy is adopted, which will save the local information of the image itself, and enhance the generalization ability of the model. In order to verify the advantages of the improved DBN algorithm model, the classification results of DBN, KNN, random forest and SVM have been compared. And the results show that classification accuracy of the improved DBN has been greatly improved, which is increased by about 2.5% compared to DBN. The improved DBN classification results are processed then, including connected areas marking, noise removal, morphological transformation and edge extraction, and the boundary information of the building is obtained according to the target shape characteristics. Finally, the experiment on the morphological characteristics of the building also shows it can extract better edge information of the building.     

Building capability throughout a change effort: leading the transformation of a police agency to community policing

This case describes a change effort to move a police agency to become a community policing organization. The community policing effort was seen as a means to make a transformational change to become a learning organization with the goal of improving the delivery of police services. The case describes the steps taken to meet the new vision of community policing as well as the steps taken to deal with the challenges or realities of trying to make change happen. The lens for this case is the leadership role across the stages of change (exploration, planning, implementation, monitoring and institutionalization) in building capacity within the organization to sustain the change effort. The capacity building focused on incorporating systems thinking into the mindset of the members of the organization, breaking down the command and control mindset by building a new norm around high involvement of committed teams, and developing skill sets to support continuous learning and improvement in order to align organizational systems. A key lesson learned is that effective leaders do not just prepare an organization prior to a change effort. They must have the patience to constantly build the capacity for change among organizational members throughout the various stages of the change effort.     

A Dyadic Analysis of the Between‐ and Within‐System Alliances on Distress

To read this article's abstract in both Spanish and Mandarin Chinese, please visit the article's full‐text page on Wiley InterScience ( http://interscience.wiley.com/journal/famp ). This study examines the relationship between the therapeutic alliance and distress using the couple rather than the individual as the unit of analysis. One hundred and seventy‐three couples receiving treatment for relational distress at two university clinics participated in this study. The actor–partner interdependence model was used to analyze the relationship of each partner's between‐ and within‐system alliance scores and distress at session four. Results provide support for actor effects on relational distress for both male and female partners and for actor effects on psychological distress for female partners. Limited support was found for partner effects on distress. Furthermore, results indicate that the alliance between partners is a stronger predictor of improvement in early sessions in comparison with the alliance between the individual and the therapist.     

Alliance and Group Cohesion in Relationship Education

Relationship education programs have been shown as an effective way to increase relationship functioning. There is less known about how process factors, such as alliance with the leader or group dynamics, affect outcomes in these interventions. We examined group cohesion and alliance with the leader in a relationship education program tailored for individuals. Specifically, we examined whether participants' ratings (n = 126) of the group cohesion and alliance with the leader were associated with changes in relationship adjustment, relationship confidence, and communication quality from pre‐ to postintervention. The results demonstrated that participants' perceptions of the cohesion among the members in their relationship education group, but not the leader–participant alliance, made a significant contribution to the changes in participants' relationship functioning. These results suggest that the group dynamics among the members in the group are important ingredients in relationship education. Implications for relationship programs are provided.

Building Blocks to Portability: Culmination of the 20/20 Initiative

The profession of counseling has now endorsed a consensus licensure title and scope of practice for all U.S. states and jurisdictions. This article describes the development of the title and scope of practice through the Building Blocks to Portability Project of the 20/20: A Vision for the Future of Counseling initiative. Outcomes and implications of this final stage of the 20/20 project intended to ease interstate licensure portability are presented.     

Long-term memory in pigeons: I. The role of discrimination problem difficulty assessed by reacquisition measures II. The role of stimulus modality assessed by generalization slope

Pigeons learned either an easy or a difficult line angle discrimination (Experiment 1) or wavelength discrimination (Experiment 2), and then they were given a reacquisition test of retention after delays of 1 min, 1 day, or 1 week. Both percentage of responses to the S+ in the initial 10-trial block and number of blocks to criterion showed a progressive memory loss which was greater for the difficult problem. These results extend recent findings by using a free operant rather than a discrete trial task and by varying problem difficulty by altering the dimensional separation between training stimuli. In Experiment 3, pigeons were given variable interval training with either a wavelength or a line angle stimulus, and then they were tested for generalization in extinction after delays of 1 min, 1 day, and 1 week. With both dimensions, the relative gradients became progressively flatter with increasing delay intervals. This replicates earlier findings and extends them to the line angle dimension. The evidence of substantial forgetting in the first 24 h in all three experiments suggests that operant free-response procedures are more sensitive to forgetting effects than are discrete trial tasks.
