Antisociality and the Construct of Psychopathy: Data From Across the Globe

Abstract: Previous theory and research on the structural, longitudinal, and genetic nature of psychopathy have provided strong conceptual and empirical evidence that overt antisociality is a component of the psychopathy construct (Hare & Neumann, 2008, 2010; Lynam & Miller, 2012). However, determination of the strength of the association between antisociality and other psychopathic features has not been explored systematically. The current article draws on previously published large North American studies, as well as data from across the globe, to estimate the strength and pattern of the associations between overt antisociality and other psychopathic domains in a diverse set of samples. Structural equation modeling was used to estimate model parameters from samples that had data on either the Psychopathy Checklist-Instruments (PCL-R, PCL: YV, PCL: SV) or self-report assessments that have known latent structures (SRP, B-Scan 360). In addition, two relatively large samples (male offenders and young adult males), assessed with both the PCL-R and the SRP, provided an opportunity to examine the link between antisociality and the other psychopathy domains across different assessment methods. The overall findings indicate that the associations were moderate to strong, depending on the nature of the sample, and clearly indicate that antisociality is a core component of the psychopathy construct.

Patch dynamics and environmental heterogeneity in lotic ecosystems

Abstract: We reviewed concepts of patch dynamics and environmental heterogeneity and their applications to the study of fluvial ecosystems, with emphasis on research published in J-NABS. We discuss several important papers synthesizing theories and findings on this topic and reports of descriptive and experimental research. A large body of research, much of it published in J-NABS, has demonstrated how spatial and temporal variation influences population, community, and ecosystem patterns and processes in fluvial ecosystems. Conceptual models of patch dynamics can be traced to 2 basic approaches: 1) the landscape ecology perspective and 2) the metacommunity perspective. The former focuses on how spatial patterns are created and affect ecological processes over variable scales of space and time, whereas the latter emphasizes the important influence of periodic disturbances, refugia, and dispersal in maintaining nonequilibrium communities within patch mosaics. The origin of the metacommunity Patch Dynamics Con...

Service quality, customer satisfaction, and behavioral intentions in fast‐food restaurants

Abstract: Purpose – This study aims to explore the potential dimensions of service quality, and examine the relationship among service quality, food quality, perceived value, customer satisfaction and behavioral intentions in fast‐food restaurants (FFRs).Design/methodology/approach – The construct reliability and validity was assessed using exploratory factor analysis and confirmatory factor analysis. Structural equation modeling was employed to estimate the relationship among service quality, customer satisfaction, and behavioral intentions.Findings – Results indicated that five dimensions were significant: tangibles, reliability/responsiveness, recovery, assurance, and empathy. Service quality and food quality were two main determinants of customer satisfaction. The insignificance of perceived value is potentially due to the homogeneous nature of the construct within the FFR group rather than the importance of the perceived value construct within food service.Originality/value – The FFR success model, using the o...
