Interactions between earthworms and arsenic in the soil environment:a review

Chemical pollution of the environment has become a major source of concern. In particular, many studies have investigated the impact of pollution on biota in the environment. Studies on metalliferous contaminated mine spoil wastes have shown that some soil organisms have the capability to become resistant to metal/metalloid toxicity. Earthworms are known to inhabit arsenic-rich metalliferous soils and, due to their intimate contact with the soil, in both the solid and aqueous phases, are likely to accumulate contaminants present in mine spoil. Earthworms that inhabit metalliferous contaminated soils must have developed mechanisms of resistance to the toxins found in these soils. The mechanisms of resistance are not fully understood; they may involve physiological adaptation (acclimation) or be genetic. This review discusses the relationships between earthworms and arsenic-rich mine spoil wastes, looking critically at resistance and possible mechanisms of resistance, in relation to soil edaphic factors and possible trophic transfer routes.

Persistent income poverty and deprivation in the European Union: An analysis of the first three waves of the European Community Household Panel

Poverty research has increasingly focused on persistent income poverty, both as a crucial social indicator and as a target for policy intervention. Such an approach can lead to an identification of a sub-set of poor individuals facing particularly adverse circumstances and/or distinctive problems in escaping from poverty. Here we seek to establish whether, in comparison with cross-sectional measures, persistent poverty measures also provide a better measure of exclusion from a minimally acceptable way of life and relate with other important variables in a logical fashion. Our analysis draws upon the first three waves of the ECHP and shows that a persistent poverty measure does constitute a significant improvement over its cross-sectional counterpart in the explanation of levels of deprivation. Persistent poverty is related to life-style deprivation in a manner that comes close to being uniform across countries. The measure of persistence also conforms to our expectations of how a poverty measure should behave in that, unlike relative income poverty lines, defining the threshold level more stringently enables us to identify progressively groups of increasingly deprived respondents. Overall the persistent poverty measure constitutes a significant advance on cross-sectional income measures. However, there is clearly a great deal relating to the process of accumulation and of erosion of resources, which is not fully captured in the persistent poverty measure. In the absence of such information, there is a great deal to be said for making use of both types of indictors in formulating and evaluating policies while we continue to improve our understanding of longer-term processes.

Marginalization, deprivation, and fatalism in the Republic of Ireland. Class and underclass perspectives

The emergence of large-scale long-term unemployment in the Republic of Ireland suggests that it might provide an interesting case to which to apply the concept of an 'underclass'. In this paper we explore the relationship between labour-market marginality, deprivation, and fatalism. The available evidence in relation to both social isolation and milieu effects suggests that the term 'underclass' can have only a very limited applicability in the Irish case. Instead, what we ate confronted with is different types of working-class marginalization arising from the rapid and uneven nature of class transformation in Ireland and changing patterns of emigration. In relation to what we have termed 'pervasive marginalization' the costs of economic change have been borne disproportionately by those members of the younger cohorts originating in the lower working class rather than by those in particular locations. The evidence relating to the social and psychological consequences of labour-market detachment, rather than providing support for the value of an 'underclass' perspective, confirms the continued relevance of class analysis.

The Casual Buttress:Certainty and Contingency in the Study of the Vernacular

Impromptu accretions such as the buttresses in Robin Walkers photograph are moments that are familiar in the architecture of the everyday. Indeed the buttress is a very common occurrence with these cottages in particular, their mud walls being poor at resisting concentrated lateral loading. While not always required the buttress emerges when requirements to create spaces to support inhabitation are at odds with the external form and construction of the buildings. These points of disjunction are resolved in an additive fashion externally. The location varies from structure to structure, occasionally the buttress is be used as a point of connection for further structures, becoming subsumed in outbuildings or walls. This preponderance to variety means that it is omitted from the reductive drawings of type that classify these buildings and yet it occurs in enough for it to have a fundamental and transformative relationship to the generality of cottages.
What is of interest is not so much what these structures hold in common, but rather what differentiates them. It is their capacity for variety within a defined range which allows them at once to speak at once of broader social structures and of a specific place and person.
Using the above observation this paper treats of the failure of architectural typological studies of the vernacular to derive anything other than formal exemplars, and posits an alternative approach based on a focus on the technical construction of such buildings.

‘Reconsidering Dermot Bolger’s Grotesquery: Class and Sexuality in The Journey Home’

Dermot Bolger's The Journey Home (1990) narrates an often hyperbolic and overblown diatribe against a litany of social and political ills, which elicited frequently critical responses to the novel from reviewers. Yet Bolger's seminal work remains both popular and controversial because of its capacity to shock and upbraid the false morality of Irish society--a society that the author considered to be riven by class inequalities and official abuses. Bolger employs sexual abuse as a metonym for political corruption in the novel, and this essay explores The Journey Home's surreal story of youth in a working-class Dublin suburb in light of more recent revelations of Ireland's legacy of institutional sexual abuse.

Constructing the 'gay gene' in the news:Optimism and skepticism in the US and British press

In the 1990s the discovery of a 'gay gene' was widely reported in the news media, often as front-page stories. Focusing on the print media presentation of Dean Hamer's 1993 and 1995 scientific papers reporting finding a genetic marker for homosexuality, we examine how these studies were framed in a selected sample of US and British newspapers and news magazines. We found disparate constructions of the 'gay gene' in each press culture. The US press reported Hamer's study as good science and treated it with 'cautious optimism' while the British press reported the research as 'the perils of the gay gene.' We discuss how these studies received such widespread attention and the sources and implications of the variant images of the 'gay gene' in the news.

Uses of expertise:Sources, quotes, and voice in the reporting of genetics in the news

Science journalists call upon experts for background and for clarification and comment on scientific findings. This paper examines how science writers choose and use experts, and it focuses on several cases of reporting about genetics and behavior. Our research included two sources of data: interviews with 15 science reporters and three print media samples of coverage of genetics and behavior - alcoholism (between 1980-1995), homosexuality (in 1993 and 1995), and mental illness (between 1970-1995). Science reporters seek relevant and specific experts for nearly every story. Good sources are knowledgeable, are connected to prestigious institutions, are direct and articulate and don't overqualify statements, and they return phone calls. The mean number of experts quoted was 2.8 per story, differing for alcoholism (3.5), homosexuality (2.8), and mental illness (2.6). Researchers and scientists predominated among experts quoted. Quotes were used to provide context, give legitimization, as explication, to provide a kind of balance, and to outline implications. For the homosexuality sample, a significantly greater percentage of activists and advocates were quoted (21 percent compared with 5 percent and 1 percent in other samples, X <0.0001). "Lay" quotes for alcoholism and mental illness were minimal. Except for homosexuality, whose advocates are organized, those "affected" do not have a voice in genetics news stories.
