Comprehensive neighbourhood mapping: developing a powerful tool for child protection

This paper proposes ‘comprehensive neighbourhood mapping’ as a schema for gathering and interpreting information within a given geographical area which is informed by imaginative thinking about the safety of children and young people from sexual crime. It would build upon current forms of profiling by local authorities, health authorities and central Government. CNM would actively involve local people, in partnership with agencies, in ‘mapping’ danger points and support points. Eight components are discussed, including environmental issues, locations of sex offenders, sites where teenagers meet and share information, supportive individuals and organizations. Some issues for pilot projects are discussed, including the need to set up planning and implementation groups and to integrate CNM into wider child protection and community safety strategies. CNM is grounded in an ecological perspective which sees partnership approaches as essential and believes an overarching view of neighbourhood needs, based on detailed local information and understanding of how different forms of harm interconnect, is crucial in developing child protection strategies. At times of acute official anxiety about community ‘lynch‐mob’ reactions to known paedophiles, CNM aims to build communities which instead are informed and thoughtful about child protection.

On the logic of common belief and common knowledge

The paper surveys the currently available axiomatizations of common belief (CB) and common knowledge (CK) by means of modal propositional logics. (Throughout, knowledge — whether individual or common — is defined as true belief.) Section 1 introduces the formal method of axiomatization followed by epistemic logicians, especially the syntax-semantics distinction, and the notion of a soundness and completeness theorem. Section 2 explains the syntactical concepts, while briefly discussing their motivations. Two standard semantic constructions, Kripke structures and neighbourhood structures, are introduced in Sections 3 and 4, respectively. It is recalled that Aumann's partitional model of CK is a particular case of a definition in terms of Kripke structures. The paper also restates the well-known fact that Kripke structures can be regarded as particular cases of neighbourhood structures. Section 3 reviews the soundness and completeness theorems proved w.r.t. the former structures by Fagin, Halpern, Moses and Vardi, as well as related results by Lismont. Section 4 reviews the corresponding theorems derived w.r.t. the latter structures by Lismont and Mongin. A general conclusion of the paper is that the axiomatization of CB does not require as strong systems of individual belief as was originally thought — onlymonotonicity has thusfar proved indispensable. Section 5 explains another consequence of general relevance: despite the infinitary nature of CB, the axiom systems of this paper admit of effective decision procedures, i.e., they aredecidable in the logician's sense.     

Taking Stock of Neighbourhood Planning in England 2011–2016

Neighbourhood planning (NP) as enabled by the 2011 Localism Act in England has precipitated a considerable literature discussing its potential, limitations and likely shortcomings referenced against government rhetoric and the reporting of initial experiences of the process. This paper provides an overview of the current literature on neighbourhood planning and sets out how it has been received and practised across England drawing on empirical evidence. The extent of take-up and the experience of those involved in the first five years of neighbourhood planning is used to consider how community-led planning may be designed and used following operational principles of inclusivity, capacity-building and adding value.     

A dimensionality reduction method of continuous dependent variables based supervised Laplacian eigenmaps

Dimensionality reduction is one of the important preprocessing steps in high-dimensional data analysis. In this paper we propose a supervised manifold learning method, it makes use of the information of continuous dependent variables to distinguish intrinsic neighbourhood and extrinsic neighbourhood of data samples, and construct two graphs according to these two kinds of neighbourhoods. Following the idea of Laplacian eigenmaps, we reveal that on the low-dimensional manifold the neighbourhood structure can be preserved or even improved. Our approach has two important characteristics: (i) it uses dependent variables to find an informative low-dimensional projection which is robust to noisy independent variables and (ii) the objective function simultaneously enlarges the distance between dissimilar samples and pushes similar samples close to each other according to the graph constructed with the help of continuous dependent variables. Our experiments demonstrate that the effectiveness of our method is over their traditional rivals.     

The European Union in the flows of international students: attractiveness and inconsistency

This paper aims to describe the overall pattern of flows of international students and to determine the factors that can explain the variation of countries' attractiveness. In a second step, it assesses the position of the European Union as a whole in these flows at the global level. Is the EU strong enough in the global competition to attract the best brains? Besides, it shows how attractiveness factors can vary according to the profile of a sample of European Union member countries. In the third section of the paper, we raise some reflexions on the relations of the EU with its neighbourhood with respect to the flows of international students. In fact, the EU may not be able to maintain its status as a major power if it does not better regulate its relations with neighbour countries, especially in the domain of higher education and students' mobility.     

浅析街道党组织的历史变迁

中国的街道党组织经历了三个历史阶段的变迁。建国初期和向社会主义过渡时期,中国共产党开始接管城市并公开和建设基层党组织,但是街道范围内的党建不是重点。计划经济体制条件下,在单位制社会结构中,街道党组织总体来说处于边缘地位。市场经济体制条件下,兴起了社区建设的浪潮,在推进社区建设的同时,各大中小城市对于街道党组织建设进行了积极有益的探索,街道社区党组织走出边缘化并积极发挥作用。     

The local geographies of welfare in Tunisia: Does neighbourhood matter?*

Amara M, Ayadi M. The local geographies of welfare in Tunisia: Does neighbourhood matter? The aim of this article is to show that spatial analysis techniques outperform non‐spatial statistical counterparts for understanding the geographic determinants of welfare and poverty in Tunisia. First, an Exploratory Spatial Data Analysis, based on a Geographical Information System, was conducted to visualise the local spatial structure of welfare. Second, a spatial autoregressive (SAR) model and a geographically weighted regression (GWR) model, respectively, were used to deal with both spatial autocorrelations and unobserved spatial heterogeneity of households' behaviours. Spatial and non‐spatial models were compared according to their predictive performances. Results of this case study confirm that SAR and GWR spatial models are preferable to the traditional non‐spatial regression model and that they give a better approximation of the Tunisian poverty map.     

On the trimmed mean and minimax-variance L-estimation in Kolmogorov neighbourhoods

We consider the properties of the trimmed mean, as regards minimax-variance L-estimation of a location parameter in a Kolmogorov neighbourhood K() of the normal distribution: We first review some results on the search for an L-minimax estimator in this neighbourhood, i.e. a linear combination of order statistics whose maximum variance in K_t() is a minimum in the class of L-estimators. The natural candidate – the L-estimate which is efficient for that member of K_t,() with minimum Fisher information – is known not to be a saddlepoint solution to the minimax problem. We show here that it is not a solution at all. We do this by showing that a smaller maximum variance is attained by an appropriately trimmed mean. We argue that this trimmed mean, as well as being computationally simple – much simpler than the efficient L-estimate referred to above, and simpler than the minimax M- and R-estimators – is at least “nearly” minimax.     

Minority ethnicity,social status and Uyghur community involvement in urban Xinjiang

Using a dataset (n = 4,012) from a 2001 survey in Xinjiang, I examine the effect of minority status and social status on neighbouring behaviour in urban China. Data analysis indicates that Uyghur Muslims are more neighbouring than Han Chinese. However, there is no evidence that the Uyghur approach to neighbourhood interaction can be attributed to Uyghur culture as many inter-group differences fade away once ethnic parity in social status is attained. I use my study to consider some methodological approaches used in research on ethnic behaviour in China.     

Ethnic differences in neighbourly relations in urban China

Using data collected in Lanzhou, this paper examines the effect of minority ethnicity on neighbourly relations in China. It shows that the Hui as a whole express a higher level of satisfaction at relations with neighbours than the Han do. It also shows that the Hui advantage is removed with key background characteristics controlled. Finally, this paper shows intra-group variation among the Hui. These findings suggest that social status is a better predictor of neighbourly relations than the focus on inter-group contrast in traditionality in the existing scholarship of the Hui. Both inter- and intra-group variation in urban life must be examined to attain a more balanced picture of Hui Muslims in China.
