The link between psychopathy and crime is well-known and a large body of literature has provided empirical support. However, the stability hypothesis of psychopathy has been a critical issue, and there are only a small number of stability studies adopting a developmental perspective. To fill this gap, the current study aims to identify the developmental pathways for the comprehensive psychopathic traits scale and three dimensions across the transition from adolescence to adulthood. The majority of adolescents show stability in their psychopathic traits from adolescent to early adulthood, whereas a small proportion of youth show changes. The findings from this study provide supports for the notion of early identification of young psychopathy. Theoretical and practical implications are discussed.

This review covers the contributions of cognitive trainings to stability in cognitive, everyday, and brain functioning across adulthood. For these functional domains, relevant types of empirical evidence were defined for training-induced enhancement in absolute, differential, and dimensional stability in the light of developmental decline. The state of research regarding these types of evidence is presented. Little data were generally available on the effects of cognitive trainings on the stability of everyday and brain functioning and across all covered domains for their contributions to differential stability. There was sound empirical support for training-induced enhancements of absolute and dimensional cognitive stability across adulthood. The theoretical, methodological, and practical implications of these findings are discussed.

The stability of steel-slag road materials remains a critical issue in their utilization as an aggregate base course. In this pursuit, the present study was envisaged to investigate the effects of fly ash on the mechanical properties and expansion behavior of cement-fly-ash-stabilized steel slag. Strength tests and expansion tests of the cement-fly-ash-stabilized steel slag with varying additions of fly ash were carried out. The results indicate that the cement-fly-ash-stabilized steel slag exhibited good mechanical properties. The expansion rate and the number of bulges of the stabilized material reduced with an increase in the addition. When the addition of fly ash was 30–60%, the stabilized material was not damaged due to expansion. Furthermore, the results of X-CT, XRD and SEM-EDS show that fly ash reacted with the expansive component of the steel slag. In addition, the macro structure of the stabilized material was found to be changed by an increase in the concentration of the fly ash, in order to improve the volumetric stability. Our study shows that the cement-fly-ash-stabilized steel slag exhibits good mechanical properties and volumetric stability with reasonable additions of fly ash.

Purpose – The purpose of this paper is to explore the claim that the tie-break criterion introduced under the Equality Act 2010 is not really positive action as is claimed by its government sponsors. It evaluates this claim by locating the tie-break into equal opportunities theory, taking into account merit considerations, and reviews its potential implications. Design/methodology/approach – A conceptual discussion of the tie-break. Findings – The paper concludes that the tie-break is not positive action, nor is it positive discrimination. It employs the framework established by Forbes (1991) and attempts to locate it in theoretical discussions of the need to refine merit to take identity characteristics into account. While it could serve to make a more sophisticated approach to merit possible it fails to achieve its implicit potential in this regard. Research limitations/implications – The paper is conceptual and will benefit from empirical support in the future. Practical implications – Practically, the tie-break promises to add some greater clarity to the muddled understanding of equal opportunities and diversity that underpins much policy and legislation. As a result it will arguably prove hard to implement and will carry other associated problems. Social implications – Socially, the tie-break, mis-represented as it currently is, promises to create greater uncertainty around the nature and purposes of equality of opportunity. Consequently, it could exacerbate tensions and hostilities and promote significant resistance to “equality” measures. Originality/value – This paper is an original conceptual piece that will shine a light on an important legal innovation. The tie-break is not what it is described to be and carries both potential and threat for advocates of equality of opportunity. In pursuing socially significant outcomes of this type, conceptual accuracy and transparency are vital, and this paper contributes to this endeavour.

Three Dimensional Simulations

Numerical simulations of the evolution of gravity wave spectra of fairly narrow bandwidth have been performed both for two and three dimensions. Simulations using the nonlinear Schrödinger (NLS) equation approximately verify the stability criteria of Alber (1978) in the two-dimensional but not in the three-dimensional case. Using a modified NLS equation (Trulsen et al. 2000) the spectra ‘relax’ towards a quasi-stationary state on a timescale (ε2ω0)−1. In this state the low-frequency face is steepened and the spectral peak is downshifted. The three-dimensional simulations show a power-law behaviour ω−4 on the high-frequency side of the (angularly integrated) spectrum.

We introduce a stabilized conforming mixed finite element method for a macroscopic model in micromagnetics. We show well-posedness of the discrete problem for higher order elements in two and three dimensions, develop a full a priori analysis for lowest order elements, and discuss the extension of the method to higher order elements. We introduce a residual-based a posteriori error estimator and present an adaptive strategy. Numerical examples illustrate the performance of the method.

Purpose The purpose of this paper is to predict the concrete pouring production rate by considering both construction and supply parameters, and by using a more stable learning method. Design/methodology/approach Unlike similar approaches, this paper considers not only construction site parameters, but also supply chain parameters. Machine learner fusion-regression (MLF-R) is used to predict the production rate of concrete pouring tasks. Findings MLF-R is used on a field database including 2,600 deliveries to 507 different locations. The proposed data set and the results are compared with ANN-Gaussian, ANN-Sigmoid and Adaboost.R2 (ANN-Gaussian). The results show better performance of MLF-R obtaining the least root mean square error (RMSE) compared with other methods. Moreover, the RMSEs derived from the predictions by MLF-R in some trials had the least standard deviation, indicating the stability of this approach among similar used approaches. Practical implications The size of the database used in this study is much larger than the size of databases used in previous studies. It helps authors draw their conclusions more confidently and introduce more generalised models that can be used in the ready-mixed concrete industry. Originality/value Introducing a more stable learning method for predicting the concrete pouring production rate helps not only construction parameters, but also traffic and supply chain parameters.

Critical behaviors in quenched random-spin systems with N-spin component are studied in the limit M → 0 of the non-random MN-component models by means of the renormalization group theory. As the static critical phenomena the stability of the fixed points is investigated and the critical exponents η[~ O(ε3); ε ≡ 4 – d], γ, α, and crossover index [Formula: see text] and the equation of state [~ O(ε)] are obtained. Within the approximation up to the order ε2, even the random-spin systems with N = 2 or 3 are unstable in the three dimensions and the pure systems are stable there.

Abstract. Background: The current research into interoception distinguishes between interoceptive accuracy (IAcc), the accurate detection of internal sensations (e.g., heartbeats) as measured by performance on objective IAcc tasks, and interoceptive sensibility (IS), the subjective belief concerning one’s own experience of internal sensations as measured either through self-report questionnaires or through one’s confidence in the accuracy during an IAcc task. Aims: As the two measures of IS, however, are usually uncorrelated and show differential relationships to IAcc, we suggest different types of IS, a general IS and a specific IS. Further, based on a growing body of research linking IAcc and IS to physical and mental diseases, the development of interoception across the adult lifespan is of importance. Methods: Using Structural Equation Modeling the present paper investigates the relationships among IAcc assessed by a heartbeat counting task, and the two proposed dimensions of IS in 138 participants ( Mage = 42.67, SDage = 18.77). Furthermore, we examine age-related differences in IAcc, as well as in general and specific IS. Results: In terms of the relationship between the three dimensions, general and specific IS were weakly correlated and exhibited different relationships to IAcc. Further, we found different age effects on the three interoceptive dimensions. Whereas IAcc decreased with age, specific IS tend to increase with age, and general IS remained unaffected by age. Conclusion: The findings provide further empirical support for a dissociation between general and specific IS and raised important questions concerning the relation between interoceptive accuracy and the emergence of physical diseases in older age.

In a given year, one in five people incarcerated in the U.S. prisons is locked in solitary confinement. We study solitary confinement along three dimensions of penal harm: (1) material deprivation, (2) social isolation, and (3) psychological distress. Data from a longitudinal survey of incarcerated men who are interviewed at baseline in solitary confinement are used to contrast the most extreme form of penal custody with general prison conditions observed at a follow-up interview. Solitary confinement is associated with extreme material deprivation and social isolation that accompanies psychological distress. Distress is greatest for those with histories of mental illness. Inactivity and feelings of dehumanization revealed in qualitative interviews help explain the distress of extreme isolation, lending empirical support to legal arguments that solitary confinement threatens human dignity.
