Partial order scalogram analysis with base coordinates (POSAC): Its application to crime patterns in all the states in the United States

In this paper, a new nonmetric method called POSAC is presented and illustrated through an analysis of the crime patterns of all the states in the United States. POSAC is a graphical technique for the display of multivariate data in a two-dimensional space. It maps the rows (e.g., states) of a matrix in a way that maximizes the preservation of theirpartial order, with similar states located in close proximity on the map. POSAC is based on the partial order among observations rather than their actual magnitude. POSAC seems to bear the same relationship to the principal-component analysis (PCA) as that borne by the median to the arithmetic mean. As a matter of fact, POSAC is a form of ordinal factor analysis. Its advantage over PCA is its robustness to the data. The technique enables observations and variables to be studied simultaneously. Seven index crime categories are analyzed. In order to demonstrate the utility of POSAC in detecting changes in crime patterns over time, we included in our analysis three selected years: 1944, 1965, and 1987. The results for the year 1987 are compared to those obtained by PCA.     

Do legal variables predict police decisions regarding the prosecution of juvenile offenders?

This study investigated whether legal variables predict police dispositions as regards the prosecution of juveniles. For this purpose first apprehensions of a sample of 479 Israeli adolescents (aged 13.5–15.5) in a one-year period were analyzed. The association between the legal variables and police dispositions was analyzed separately within four hierarchical stages of involvement with the juvenile justice system. Previous referral to court and previous court appearance were found to be excellent predictors of police decision to prosecute. However, in the earlier stages of involvement with the juvenile justice system, (i.e., when juveniles had no previous court referrals or appearances), the predicting power of the few available legal variables (type and seriousness of offense and number of previous police apprehensions) was found to be negligible. In the discussion of the findings, the contradicting labeling and deterrence theories are applied to the functioning of the juvenile units within the police: The present study has empirically identified the specific point where police decision-making reflects a switch-over from the labeling to the deterrence approach. Some suggestions for future research are put forward in order to improve the predictability of police dispositions at the early stages of the juvenile's involvement with the criminal justice system.     

Protection and Dignity in Johannesburg: Shortcomings of South Africa's Urban Refugee Policy

Since the end of apartheid, South African cities have becomedestinations for refugees and asylum seekers from across Africa.In line with its constitutional commitments to human rightsand dignity, South Africa has enacted a refugee policy intendedto maximize freedom and protection by promoting refugees' temporaryintegration into local communities. In doing so, the law guaranteesfreedom of movement, access to many social services, and rightsto compete in labour and housing markets. This article arguesthat because refugees and asylum seekers are effectively unableto convert these legal entitlements into effective protection,South Africa has failed to meet its domestic and internationalobligations. This argument draws particular attention to institutionalfailures in determining refugee status and issuing recognizableidentity documents; denial of essential social services; andabuse at the hands of law enforcement agents. It concludes bysuggesting a positive obligation for the state to counter thefull range of obstacles that prevent asylum seekers and refugeesfrom securing effective protection.     

PLANNING AND PARTICIPATION IN CITIES THAT MOVE: IDENTIFYING OBSTACLES TO MUNICIPAL MOBILITY MANAGEMENT

The dual processes of rapidly transforming cities and administrative decentralisation demands that local government address human mobility as a means of countering urban poverty. Despite this imperative, local authorities are often poorly equipped to address the needs of poor and transient residents. Through an examination of four South African municipalities, this article helps to identify three critical factors working against effective responses: poor data and conceptual bias; institutional ambiguities and budgeting processes; and, ironically, participatory planning. Although any one of these could serve as a basis for an article, by taking them together, we better summarise the challenges' scope and outline areas for further research and policy intervention. The article concludes by considering these findings' practical and scholarly implications. Copyright © 2013 John Wiley & Sons, Ltd.     

Urbanisation,nativism, and the rule of law in South Africa's ‘forbidden’ cities

South Africa's political liberalisation and strengthening regional ties have engendered new patterns of immigration and urbanisation, resulting in South African migrants and non-nationals converging on the streets of previously ‘forbidden’ cities. Conflicts over space, services and livelihoods are emerging as these groups meet and compete. To settle these disputes, South African citizens and politicians regularly rely on nativist discourses that make one's rights to the city contingent on one's national origins. Efforts to exclude foreigners are in turn encouraging and legitimising new forms of bias, administrative discrimination and anti-foreigner policing. Bolstered by official sanction, these are creating urban ‘zones of exception’, areas in which the state authorises its agents to work outside the law. Although popular among South Africans, the extra-legal harassment, detention and deportation of non-nationals has helped entrench new economies of corruption and violence that jeopardise the rights and welfare of all urban residents. While rooted in the dynamics of post-apartheid South Africa, these findings resonate with global trends in which quests to assert sovereignty through immigration controls are resulting in actions that undermine the legitimacy and founding principles of the liberal states that undertake them.
