Age-related macular degeneration (AMD), is the leading cause of blind registration in the Western World among individuals 65 years or older. Early AMD, a clinical state without overt functional loss, is said to be present clinically when yellowish deposits known as drusen and/or alterations of fundus pigmentation are seen in the macular retina. Although the etiopathogenesis of AMD remains uncertain, there is a growing body of evidence in support of the view that cumulative oxidative damage plays a causal role. Appropriate dietary antioxidant supplementation is likely to be beneficial in maintaining visual function in patients with AMD, and preventing or delaying the progression of early AMD to late AMD. The Carotenoids in Age-Related Maculopathy (CARMA) Study is a randomized and double-masked clinical trial of antioxidant supplementation versus placebo in 433 participants with either early AMD features of sufficient severity in at least one eye or any level of AMD in one eye with late AMD (neovascular AMD or central geographic atrophy) in the fellow eye. The aim of the CARMA Study is to investigate whether lutein and zeaxanthin, in combination with co-antioxidants (vitamin C, E, and zinc), has a beneficial effect on visual function and/or prevention of progression from early to late stages of disease. The primary outcome is improved or preserved distance visual acuity at 12 months. Secondary outcomes include improved or preserved interferometric acuity, contrast sensitivity, shape discrimination ability, and change in AMD severity as monitored by fundus photography. This article outlines the CARMA Study design and methodology, including its rationale.

This paper develops an understanding of creativity to meet the requirements of the decision of the Supreme Court of the United States in Feist v. Rural (1991). The inclusion of creativity in originality, in a minimal degree of creativity, and in a creative spark below the level required for originality, is first established. Conditions for creativity are simultaneously derived. Clauses negatively implying creativity are then identified and considered.
The clauses which imply creativity can be extensively correlated with conceptions of computability. The negative of creativity is then understood as an automatic mechanical or computational procedure or a so routine process which results in a highly routine product. Conversely, creativity invariantly involves a not mechanical procedure. The not mechanical is then populated by meaning, in accord with accepted distinctions, drawing on a range of discourses. Meaning is understood as a different level of analysis to the syntactic or mechanical and also as involving direct human engagement with meaning. As direct engagement with meaning, it can be connected to classic concepts of creativity, through the association of dissimilars. Creativity is finally understood as not mechanical human activity above a certain level of routinicity.
Creativity is then integrated with a minimal degree of creativity and with originality. The level of creativity required for a minimal degree is identified as intellectual. The combination of an intellectual level with a sufficient amount of creativity can be read from the exchange values connected with the product of creative activity. Humanly created bibliographic records and indexes are then possible correlates to or constituents of a minimal degree of creativity. A four stage discriminatory process for determining originality is then specified. Finally, the strength and value of the argument are considered.
Finally, the strength and value of the argument are considered.

Human motor behaviour is continually modified on the basis of errors between desired and actual movement outcomes. It is emerging that the role played by the primary motor cortex (M1) in this process is contingent upon a variety of factors, including the nature of the task being performed, and the stage of learning. Here we used repetitive TMS to test the hypothesis that M1 is intimately involved in the initial phase of sensorimotor adaptation. Inhibitory theta burst stimulation was applied to M1 prior to a task requiring modification of torques generated about the elbow/forearm complex in response to rotations of a visual feedback display. Participants were first exposed to a 30° clockwise (CW) rotation (Block A), then a 60° counterclockwise rotation (Block B), followed immediately by a second block of 30° CW rotation (A2). In the STIM condition, participants received 20s of continuous theta burst stimulation (cTBS) prior to the initial A Block. In the conventional (CON) condition, no stimulation was applied. The overt characteristics of performance in the two conditions were essentially equivalent with respect to the errors exhibited upon exposure to a new variant of the task. There were however, profound differences between the conditions in the latency of response preparation, and the excitability of corticospinal projections from M1, which accompanied phases of de-adaptation and re-adaptation (during Blocks B and A2). Upon subsequent exposure to the A rotation 24h later, the rate of re-adaptation was lower in the stimulation condition than that present in the conventional condition. These results support the assertion that primary motor cortex assumes a key role in a network that mediates adaptation to visuomotor perturbation, and emphasise that it is engaged functionally during the early phase of learning.

Green’s (2007, 2008, 2009) recent comparative work on child-on-child homicides in England and Norway has drawn attention to political-cultural explanations to account for differences in levels of state punitiveness. His work finds support for the distinction made by Arend Lijphart (1999) between consensus and majoritarian democracy, through his argument that English majoritarian political culture created powerful incentives to exploit the homicide of James Bulger in ways that were not present in Norway. Drawing on comparative research in Ireland, Scotland and New Zealand, this article joins with Green in enlisting political culture as an important explanatory variable yet challenges the usefulness of Lijphart’s typology in explaining penal difference.

Relying on Brown’s (2005a, b) thesis that contemporary shifts in penal policy are best understood as a reprisal of colonial rationality, so that offenders become ‘non-citizens’ or ‘agents of obligation’, this article argues that this framework finds support in developments in Irish criminal justice policy. Recent legislation aimed at offenders suspected of involvement in ‘organised crime’ is examined through this lens. These offenders have found themselves reconstituted as ‘agents of obligation’ with duties to furnish information about their property and movements, report to the police concerning their location and, importantly, refrain from criminal activity or face extraordinary sanctions. It is therefore argued that this paradigm is a useful heuristic device through which to understand recent developments in Irish criminal justice and elsewhere. In light of the trends observed in Ireland, certain refinements and extensions to Brown’s argument are put forward for consideration.

In a health service with limited resources we must make decisions about who to treat ?rst. In this paper I develop a version of the restoration argument according to which those whose need for resources is a consequence of their voluntary choices should receive lower priority when it comes to health care. I then consider three possible problems for this argument based on those that have been raised against other theories of this type: that we don’t know in a particular case that the illness is self-in?icted, that it seems that all illness is self-in?icted in the sense used in my argument, and ?nally that this type of approach incorporates an unacceptable moralising element if it is to avoid giving those like ?re-?ghters a lower priority for treatment. I argue that the position outlined here has the resources to respond to each of these objections.

Milton’s Elegiarum Liber, the first half of his Poemata published in Poems of Mr John Milton Both English and Latin (1645), concludes with a series of eight Latin epigrams: five bitterly anti-Catholic pieces on the failed Gunpowder Plot of 1605, followed by three encomiastic poems hymning the praises of an Italian soprano, Leonora Baroni, singing in Catholic Rome. The disparity in terms of subject matter and tone is self-evident yet surprising in an epigrammatic series that runs sequentially. Whereas the gunpowder epigrams denigrate Rome, the Leonora epigrams present the city as a cultured hub of inclusivity, the welcome host of a Neapolitan soprano. In providing the setting for a human song that both enthrals its audience and attests to the presence of a divine power, Rome now epitomizes something other than brute idolatry, clerical habit or doctrine. And for the poet this facilitates an interrogation of theological (especially Catholic) doctrines. Coelum non animum muto, dum trans mare curro wrote the homeward-bound Milton in the autograph book of Camillo Cardoini at Geneva on 10 June 1639. But that this was an animus that could indeed acclimatize to religious and cultural difference is suggested by the Latin poems which Milton “patch [ed] up” in the course of his Italian journey. Central to that acclimatisation, as this chapter argues, is Milton’s quasi-Catholic self-fashioning. Thus Mansus offers a poetic autobiography of sorts, a self-inscribed vita coloured by intertextually kaleidoscopic links with two Catholic poets of Renaissance Italy and their patron; Ad Leonoram 1 both invokes and interrogates Catholic doctrine before a Catholic audience only to view the whole through the lens of a neo-Platonic hermeticism that may refreshingly transcend religious difference. Finally, Epitaphium Damonis, composed upon Milton’s return home, seems to highlight the potential interconnectedness of Protestant England and Catholic Italy, through the Anglo-Italian identity of its deceased subject, and through a pseudo-monasticism suggested by the poem’s possible engagement with the hagiography of a Catholic Saint. Perhaps continental travel and the physical encounter with the symbols, personages and institutions of the other have engendered in the Milton of the Italian journey a tolerance or, more accurately, the manipulation of a seeming tolerance to serve poetic and cultural ends.
First reviewer:
Haan: a fine piece by the senior neo-Latinist in Milton studies.
Second reviewer:
Chapter 7 is ... a high-spot of the collection. Its argument that in his Latin poetry Milton’s is a ‘quasi-Catholic self-fashioning’ stressing ‘the potential interconnectedness of Protestant England and Catholic Italy’ is striking and is advanced with learning, clarity and insight. Its sensitive exploration of the paradox of Milton’s coupling of humanistically complimentary and tolerant address to Roman Catholic friends with fiercely Protestant partisanship demonstrates that there is much greater complexity to his poetic persona than the self-construction and self-presentation of the later works would suggest. The essay is always adroit and sure-footed, often critically acute and illuminating (as, for example, in its discussion of the adjective and adverb mollis and molliter in Mansus, or in the identification in n. 99 of hitherto unnoticed Virgilian echoes). It has the added merits of being very well written, precise and apt in its citation of evidence, and absolutely central to the concerns of the volume.

The nonsteroidal anti-inflammatory drug diclofenac is extremely toxic to Old World Gyps vultures (median lethal dose -0.1-0.2 mg/kg), evoking visceral gout, renal necrosis, and mortality within a few days of exposure. Unintentional secondary poisoning of vultures that fed upon carcasses of diclofenac-treated livestock decimated populations in the Indian subcontinent. Because of the widespread use of diclofenac and other cyclooxygenase-2 inhibiting drugs, a toxicological study was undertaken in turkey vultures (Cathartes aura) as an initial step in examining sensitivity of New World scavenging birds. Two trials were conducted entailing oral gavage of diclofenac at doses ranging from 0.08 to 25 mg/kg body weight. Birds were observed for 7 d, blood samples were collected for plasma chemistry (predose and 12, 24, and 48 h and 7 d postdose), and select individuals were necropsied. Diclofenac failed to evoke overt signs of toxicity, visceral gout, renal necrosis, or elevate plasma uric acid at concentrations greater than 100 times the estimated median lethal dose reported for Gyps vultures. For turkey vultures receiving 8 or 25 mg/kg, the plasma half-life of diclofenac was estimated to be 6 h, and it was apparently cleared after several days as no residues were detectable in liver or kidney at necropsy. Differential sensitivity among avian species is a hallmark of cyclooxygenase-2 inhibitors, and despite the tolerance of turkey vultures to diclofenac, additional studies in related scavenging species seem warranted.

The research on Estonia, Latvia and Lithuania has pointed out some controversial social and political developments since the collapse of the Soviet Union. Crucially, there is a discrepancy between the governments' commitment to creating democratic political regimes, to ensuring harmonious social relations and to accommodating the ethno-cultural diversity of the resident communities. In reflecting on the legacies of the Soviet past, the book addresses the role non-titular populations have played in the process of democratisation and the relation between the states, societies and minorities in the post-Soviet Baltic states. The argument proceeds along three lines. Firstly, the book examines the institutional dimension of democratisation in the region, thereby addressing the processes of state- and nation-building as reflected in various policy-developments. Secondly, it compares the impact of ethno-cultural diversity on the development of the respective Baltic nation-states. The discussion makes clear that the framework of Baltic political communities was designed to suit the interests of the titular groups and thus resulted in the marginalisation of the minority communities. Thirdly, the book assesses the participation of minority communities in the development, criticism and improvement of state institutions and policies since independence. The analysis points out that, two decades after independence, the post-Soviet Baltic states and societies are seen by many members of the majority groups as primarily serving the interests of their ethnic community. In this situation, the members of the non-titular communities need to adapt to the majorities' perceptions in order to benefit from the achievements of democratisation.

A joint concern with multidimensionality and dynamics is a defining feature of the pervasive use of the terminology of social exclusion in the European Union. The notion of social exclusion focuses attention on economic vulnerability in the sense of exposure to risk and uncertainty. Sociological concern with these issues has been associated with the thesis that risk and uncertainty have become more pervasive and extend substantially beyond the working class. This paper combines features of recent approaches to statistical modelling of poverty dynamics and multidimensional deprivation in order to develop our understanding of the dynamics of economic vulnerability. An analysis involving nine countries and covering the first five waves of the European Community Household Panel shows that, across nations and time, it is possible to identify an economically vulnerable class. This class is characterized by heightened risk of falling below a critical resource level, exposure to material deprivation and experience of subjective economic stress. Cross-national differentials in persistence of vulnerability are wider than in the case of income poverty and less affected by measurement error. Economic vulnerability profiles vary across welfare regimes in a manner broadly consistent with our expectations. Variation in the impact of social class within and across countries provides no support for the argument that its role in structuring such risk has become much less important. Our findings suggest that it is possible to accept the importance of the emergence of new forms of social risk and acknowledge the significance of efforts to develop welfare states policies involving a shift of opportunities and decision making on to individuals without accepting the 'death of social class' thesis.

In light of recent debates on ‘public criminology’, this paper chooses to focus on teaching as a way of reaching more publics. The various characteristics of a more public and engaged discipline are discussed and applied specifically to the teaching of criminology, including the relative merits and demerits of reorienting teaching in this way. Following on from this discussion, the paper proceeds to outline some practical ways in which this vision can be realised. Given the many affinities betweenthe Burawoyan concept of public ‘-ologies’ and the scholarship of learning and teaching, an argument is advanced for teaching as one of the first steps towards the practice of a more public criminology.

Access to potable water is frequently said to be the defining world crisis of the twenty-first century. The argument is usually framed in terms of either direct environmental constraints or various totalistic views of how the political determines outcomes. There is little or no scope for the agency of practical politics. Both physical and human geographers tend to be dismissive of the possibilities of democratic politics ever resolving crises such as those of the geography of water provision, in part because of views of scientific expertise that devalue popular participation in decisions about technical matters such as water quality and distribution. Such dismissal also has much to do with a more generalized denigration of politics. Politics (the art of political deliberation, negotiation, and compromise) needs defending against its critics and many of its practitioners. Showing how politics is at work around the world in managing water problems and identifying the challenges that water problems pose for politics provides a retort to those who can only envisage inevitable destruction or a totalistic political panacea as the outcomes of the crisis of the century.

In this paper we address the question of the relative importance of within and between country differences in income and material deprivation in the European Union in the context of recent suggestions that insufficient attention has been paid to the latter. In particular, we respond to the argument that the 'state bounded' relative income approach obscures the significance of EU-wide reference groups. Making use of EU-SILC 2004, we have sought to quantify the magnitude of relevant within and between country differences and their relative impact. Overall, our analysis supports the view that the predominant frame of reference is a national one. The limited impact of European reference groups observed in our analysis does not require explanation in terms of the emergence of a European social stratification system. Furthermore, the significance of such comparisons depends not only on the expectations of those affected by European inequalities but on the degree of legitimacy afforded to ensuing demands. While an EU-wide income-threshold can provide information regarding progress of the Union towards greater social cohesion, its usage for this purpose does not require a strong sense of European identity. Given the current status of the European Social Model, it would seem unwise to attribute an undue degree of policy relevance to the relatively modest impact of EU-wide reference groups revealed in our analysis.

At risk of poverty indicators based on relative income measures suggest that within the enlarged EU societies located at quite different points on a continuum of affluence have similar levels of poverty. Substantial differences in levels of income between societies do not in themselves invalidate this approach. However, the relative income approach fails to capture the fact that, if countries are grouped in terms of level of GDP, between economic cluster differences in life-style deprivation are sharper at lower income levels. Support for the argument relating to restricted reference groups is found in relation to the contrast between the twelve most affluent EU countries and all others. The limitations of relative income poverty lines have little to do with the process of enlargement as such. Instead the major problem involves the weak association between income and deprivation in the more affluent countries. However, as a consequence of such difficulties, such indicators do not provide entirely meaningful comparisons of levels of disadvantage across economic clusters. The current analysis, rather than supporting the alternative of a focus on absolute income or an EU wide poverty line, suggests that we should take the argument for adopting a multidimensional approach to the measurement of poverty more seriously.

The literature on Social exclusion has focused attention on the processes leading to exposure to multiple disadvantage. Despite the influence this perspective has had on both academic and policy discussions, conceptual analysis has remained imprecise and empirical evidence modest. We have made use of the European Community Household Panel (ECHP) in order to examine the extent to which persistent income poverty results in multiple deprivation. Our analysis shows that only a modest proportion of the persistently poor can he characterized as being exposed to such deprivation. While persistent poverty and multiple deprivation combine to produce extremely high levels of economic strain, there is no evidence that they interact in a significant fashion. We argue that understanding deprivation is not facilitated by focusing on a cleavage between a multiply deprived minority and a comfortable majority, and we consider the policy implications of this argument.
