Computational seismic interpretation using attention models, texture dissimilarity, and learning
… novel seismic attributes based on texture dissimilarity, visual-attention theory, the modeling of human visual system, and machine learning to quantify changes and highlight geological features in a three-dimensional space. To automate the process of seismic interpretation, we develop …

The effects of similarity and dissimilarity of sexual attitudes on willingness to self-disclose
Effects of attitudinal similarity and permissiveness on patterns of self-disclosure willingness were evaluated within the framework of a 2 x 3 x 3 factorial design with two levels of similarity and three levels of permissiveness as. between-subjects variables and three topics as a within-subjects …

Exploiting Structure Information for Network Dissimilarity Characterization - Application to Disease Network Analysis and Treatment Prediction
Most cancers lack effective early disease markers, prognostic and predictive signatures, primarily due to tumor heterogeneity. As a result, we fail treating cancer heterogeneity due to multiple ways cancer initiates and develops treatment resistance. Models that represent these differences and the …

The influence of structural dimensions on similarity/dissimilarity judgements when categorizing paintings: A developmental study
… influence of structural dimensions on similarity/dissimilarity judgements when catergorizing paintings. The problem considered the structural dimensions subject matter and degree of realism and their developmental influence on the categorization of paintings. One hundred twenty subjects from …

Resource Transfer Efficiency Within Multibusiness Firms: The Effect of Dissimilarity in Managerial Specializations and Executive Compensations
The findings suggest two main conclusions: First, when optimality of a decision depends on exchange of information between specialists, and when there is some sort of competition between these specialists, differences in specializations could negatively affect efficiency of decisions in the absence …

Effects of Social Category and Value Dissimilarity in Teams: The Role of Relational and Collective Identification
… between team members' social category dissimilarity in their team in terms of nation and race/ethnic origin and their satisfaction and learning in a team. It is argued that these relations are moderated by value dissimilarity and individual team member identifications. Specifically, the …

Whistling in the Wind: Examining the Effects of Sexual Orientation Relational Demography on Individual Perceptions of Workgroup Process and Withdrawal
… between perceived workgroup sexual orientation dissimilarity and participant perceptions of group process and withdrawal. Based on the theory of relational demography within groups (Riordan, 2000) and recent research on moderators of the dissimilarity-outcome relationship (e.g., Stewart and …

The Diver's Distance
… uses a reordering of the rows and columns of a dissimilarity matrix; it then displays the ordered dissimilarity matrix (ODM) as a 2D gray-level image called an ordered dissimilarity image (ODI). Al- though successful in determining potential clustering structure of various data sets, the …

Investigating functional data with sharp local features with applications to spectroscopy
… problem is to define an efficient measure of the dissimilarity between the spectra. Indeed, a given peak in a dataset of spectra might be affected by vertical amplifications, horizontal shifts or both simultaneously, the source of those variations possibly being a significant chemical difference …

Residential segregation of blacks in Virginia cities: assessing socioeconomic factors
… at the census tract level. These indexes were, dissimilarity, interaction, and isolation. The dissimilarity index is a measure of the evenness of residential distribution of minority members. The interaction index is a measure of the probability of minority residential contact with majority …

When Being More Different and Less Visible Leads to Commitment and Justice for All
… support for high-levels of demographic dissimilarity associated with low-levels of affective commitment towards one’s organization. Contrary to the hypotheses, high-intensity telecommuting was found to be more strongly related to affective commitment, especially when procedural justice …

Machine Learning for Tract Segmentation in dMRI data
… the streamlines into a Euclidean space (call dissimilarity representation), and then in adopting a state-of-the art scalable implementation of the k-means algorithm. The dissimilarity representation is defined by selecting a set of streamlines called prototypes and then mapping any new …

Implementation of Multiple-Instance Learning in Drug Activity Prediction
… instance-based embedding using calculated dissimilarity distances. Four dissimilarity measures were employed and their performances were compared. 1-norm SVM was used for joint feature selection and classification. The approach was applied to four data sets, and the best proposed model for …

Observations on myxozoans (Myzozoa: Myxosporea) and the spatial and temporal variation in parasite assemblages of the nosestripe klipfish, Muraenoclinus dorsalis Bleeke, 1860 (Perciformes: Clinidae)
… from Granger Bay showed no significant dissimilarity in composition between summer and winter while the component communities from Kommetjie showed little dissimilarity (Global R: 0.105; p-value = 0.002). These results suggest that season or seasonassociated factors play weak roles at …

The origins and maintenance of species boundaries in Jamesbrittenia O. Kuntze (Scrophulariaceae: Manuleae)
… reinforcement of reproductive barriers. Floral dissimilarity and divergence time were found to be useful in predicting hybridization reported in the wild (p<0.0001). Species pairs susceptible to hybridization were identified on the basis of their floral dissimilarity and divergence time in order …
