The present editorial discusses whether socioeconomic status of the individual and of the neighbourhood could be important in prevalence, treatment and prevention of psychiatric morbidity. Previous research showed that patients diagnosed with mental disorders are concentrated in socioeconomically disadvantaged areas. This could be the result of (1) an association between individual socioeconomi...

Neighbourhood structures are the standard semantic tool used to reason about non-normal modal logics. The logic of all neighbourhood models is called classical modal logic. In coalgebraic terms, a neighbourhood frame is a coalgebra for the contravariant powerset functor composed with itself, denoted by 2. We use this coalgebraic modelling to derive notions of equivalence between neighbourhood s...

BACKGROUND Individuals are defined as being at ultra-high risk (UHR) for psychosis based on a combination of attenuated psychotic symptoms, help-seeking behaviour, genetic risk, and social/occupational deterioration. Limited evidence is available on whether UHR detection differs by neighbourhood, and potential explanations. AIMS To examine neighbourhood distribution of detected UHR using case...

In the context of synthetic differential geometry, we study the Laplace operator an a Riemannian manifold. The main new aspect is a neighbourhood of the diagonal, smaller than the second neighbourhood usually required as support for second order differential operators. The new neighbourhood has the property that a function is affine on it if and only if it is harmonic.

Neighbourhood structures are the standard semantic tool used to reason about non-normal modal logics. In coalgebraic terms, a neighbourhood frame is a coalgebra for the contravariant powerset functor composed with itself, denoted by 2. In our paper, we investigate the coalgebraic equivalence notions of 2-bisimulation, behavioural equivalence and neighbourhood bisimulation (a notion based on pus...

BACKGROUND Population health planning aims to improve the health of the entire population and to reduce health inequities among population groups. Socioeconomic factors are increasingly being recognized as major determinants of many aspects of health and causes of health inequities. Knowledge of socioeconomic characteristics of neighbourhoods is necessary to identify their unique health needs a...

UNLABELLED BACKGROUND Increased density of fast food restaurants is associated with increased prevalence of obesity in developed countries. However, less is known about this relationship in developing countries undergoing rapid urbanization and how differences in neighbourhood income affect the patronage of fast food outlets. The purpose of the study is to explore the differences in fast foo...

Denoising images is a classical problem in low-level computer vision. In this paper, we propose an algorithm which can remove iteratively salt and pepper noise based on neighbourhood while preserving details. First, we compute the probability of different window without free noise pixel by noise ratio, and then determine the size of window. After that the corrupted pixel is replaced by the weig...

OBJECTIVES We investigated associations of officially recorded crime and perceived neighbourhood safety with physical health, evaluating potential effect modification by gender. SETTING Nationally representative population-based survey in New Zealand. PARTICIPANTS Individual-level data from 6995 New Zealand General Social Survey (2010-2011) participants with complete data on physical health...

This study draws on the Millennium Cohort Study to explore the housing and neighbourhood circumstances of children born in England in 2000 at the age of 5 in 2006. The majority of children experienced good housing conditions. Those in social rented homes, and to a lesser extent in private rented homes too, were markedly disadvantaged in terms of family circumstances and neighbourhood deprivatio...
