Trends in bird species richness,abundance and biomass along a tropical urbanization gradient

Impacts of urbanization on biodiversity are commonly studied using urbanization gradients which provide a space-for-time substitution in estimating consequences of urban expansion. Rates of urbanization and human population growth are high in tropical countries of the developing world, which also hold most of the world’s biodiversity hot-spots, yet few studies have considered biodiversity trends along urban gradients in these regions. Bird communities across a gradient of nine sites in Uganda, from the city centre of Kampala to outlying rural locations, were studied over a six year period. These sites were ordered along an urbanization gradient using Principle Components Analysis based on habitat variables estimated at each site. Bird species richness showed a decrease from rural to urban sites, a trend especially evident in forest birds. There was no clear pattern in total abundance, total biomass or biomass per individual along the gradient. However, this latter result was heavily influenced by a colony of Marabou Storks at one site. When this species was omitted, there was evidence of a positive trend with urbanization, showing that as species richness decreased, the bird community was increasingly dominated by larger species with increasing urbanization, which were mainly scavengers able to exploit human refuse. These results provide further support for the negative impacts of urbanization on species richness, but also demonstrate trends in abundance and biomass are variable across different regions. In particular, the increasing dominance of larger species in urban areas may be relevant to certain geographic and/or socioeconomic contexts.     

Exploring the Eligibility Criteria of the Child Support Grant and its Impact on Poverty

One of the most important policy objectives in the post-apartheid South African economy is to reduce poverty. Although economic growth and job creation are the preferred sources of alleviating poverty and inequality, social grant spending has contributed significantly to reduce poverty (Van der Berg et al. in Poverty trends since the transition: what we know. Stellenbosch Economic Working Papers: 19/09. Stellenbosch: Stellenbosch University, 2009). Recently proposals were tabled by the Department of Social Development of South Africa (Fin24 in R3.3bn plan to extend child support grant to 21. http://www.fin24.com/Economy/R33bn-child-care-grant-extension-to-21-on-cards-20150316. Accessed August 7, 2015, 2015) to extend the age eligibility of the child support grant (CSG) to 21 years (at the time of writing children aged up to 18 years are eligible). This sparked an interest to investigate the impact on poverty of changes to the eligibility criteria of CSG, as well as its fiscal implications. Using person and household data from the 2010/2011 Income and Expenditure Survey, various simulations are performed to assess the impact on poverty rates and changes to social spending, given the following changes: (1) if all age-eligible children applied; (2) if all beneficiaries received the grant amount for the full 12-month duration; (3) if the age eligibility criterion is extended; and (4) if the monthly child grant income amount is revised upwards. We also examine how changes in the eligibility criteria affect the income distribution.     

EU post-accession Polish migrants trajectories and their settlement practices in Scotland

The presence and the apparent permanence of post-accession EU migrants in the UK is of significant interest to both academics and politicians. Studies have debated whether migration from new accession countries to the UK mark a new type of migration often described as ‘liquid’ and ‘open ended’, or whether these migrants will settle in the new destination countries. Based on a qualitative study of Poles who have lived in Scotland for at least six years, we observed four typologies of what we call migrants’ settling practices: (1) stayers, (2) over-stayers, (3) circular and transnational migrants and (4) economic migrants. The findings from this study demonstrate that Polish migrants do not have fixed ideas about the duration of their migration (in terms of a sense of permanence) but instead focus on diverse links, anchors or attachments in Scotland and Poland in describing their settling practices. Thus, the main contribution the article makes is to present an in-depth understanding of what settlement means from the perspective of migrants themselves. This paper concludes by providing a short comment on implications of the outcome of the Referendum on EU membership ‘Brexit’ in June 2016 on Polish migrants settling practices.     

A fortran implementation of univariate fourier series density estimation

A set of Fortran-77 subroutines is described which compute a nonparametric density estimator expressed as a Fourier series. In addition, a subroutine is given for the estimation of a cumulative distribution. Performance measures are given based on samples from a Weibull distribution. Due to small size and modest space demands, these subroutines are easily implemented on most small computers.     

Visual Sequence Learning in Infancy: Domain-General and Domain-Specific Associations with Language

Research suggests that non-linguistic sequence learning abilities are an important contributor to language development (Conway, Bauernschmidt, Huang, & Pisoni, 2010). The current study investigated visual sequence learning as a possible predictor of vocabulary development in infants. Fifty-eight 8.5-month-old infants were presented with a three-location spatiotemporal sequence of multi-colored geometric shapes. Early language skills were assessed using the MacArthur-Bates CDI. Analyses of children's reaction times to the stimuli suggest that the extent to which infants demonstrated learning was significantly correlated with their vocabulary comprehension at the time of test and with their gestural comprehension abilities 5 months later. These findings suggest that visual sequence learning may have both domain-general and domain-specific associations with language learning.     

On Sociobiology And Anthropology

Space is fundamental in any form of communal life; space is fundamental in any exercise of power (Foucault 1984:252).

The road goes regularly through groves of nutmeg and lofty kenari-tree, the latter of which serve as protection for the former. Banda [Besar] is one single mountain ridge for the whole length, stretching from East to West with sides sloping into the sea. The aforementioned plantations spread over each side of these mountains and to a marked height, yes, until almost the peaks. Our tour is completely via the mountains and mostly always within the shade of these lovely groves, yet you see scarcely a single kind of vegetation other than the nutmeg- and kanari-tree (Olivier 1979[1827]:100–101).     

Nothing to Declare: J. Hillis Miller and Zero's Paradox

In Australian law, the protection of cultural property or cultural rights is built upon generalisable notions of culture, cultural belongings and properties. These notions have tended to reflect non‐Indigenous preconceptions and, as a result, Aboriginal cultural rights have been inadequately recognised and legal protection offered has often failed to protect what is valuable and significant to Aboriginal peoples. In the context of these issues, this article considers the relationship between the representation of culture and notions of cultural identity and property.     

Beyond toleration: privacy, citizenship and sexual minorities in England and Wales

This paper examines two significant moments in sexual minority citizenship in England and Wales in relation to one of the Marshallian sets of rights, namely, civil or legal rights, focusing specifically on the Sex Offences legislation and policing practices. The first moment that will be examined here is the process whereby homosexual acts were decriminalized in the 1950s and 1960s; here special attention will be paid to the recommendations made by the Wolfenden Committee. The second moment is one we are currently experiencing, which is associated with the inclusive policing of sexual minority communities (especially lesbian, gay, bisexual and transgender communities) under the provisions of the Crime and Disorder Act 1998 and in the review of Sex Offences, especially in the consultation paper (Home Office 2000) and White Paper (Home Office 2002) associated with this review. Privacy and toleration dominate the first moment, at the same time it shall be demonstrated that privacy is also central to the British Sexual Citizenship literatures that have emerged in sociology in the post-Wolfenden context. However, as the title suggests, the second moment under examination points to the emergence of a rather more extensive sexual minority citizenship beyond the boundaries of 'homosexual privacy' (which British Sexual Citizenship Studies is not currently engaging with) and perhaps even beyond the boundaries of toleration through ever more 'inclusive' policing strategies and through the review of sex offences in which many discriminatory laws are being 'de-homosexualized'.
