On the Gorenstein and F\mathfrak{F}-cohomological dimensions

We prove that for any discrete group $G$ with finite $\mathfrak{F}$-cohomological dimension, the Gorenstein cohomological dimension equals the $\mathfrak{F}$-cohomological dimension. This is achieved by constructing a long exact sequence of cohomological functors, analogous to that constructed by Avramov and Martsinkovsky, containing the $\mathfrak{F}$-cohomology and complete $\mathfrak{F}$-cohomology. As a corollary we improve upon a theorem of Degrijse concerning subadditivity of the $\mathfrak{F}$-cohomological dimension under group extensions.Comment: 13 pages, no figure

A century of minimum wages in Britain

Simon Deakin and Francis Green trace the history from the trade boards first enacted in October 1909 to today's National Minimum Wage.

Transcending the carceral archipelago: existential, figurational and structurational perspectives on power and control

From Foucault (1977) through to Cohen (1985) and Feeley and Simon (1992) criminological thinking about punishment has been dominated by penal rationalities of power and control. This has led to an under-theorised notion of the individual in criminology (Green 2011). As society and penality become increasingly ‘re-emotionalised’ (Karstedt 2011) justice and punishment are invested with a new narrative and expressive dimensions. Drawing on Sartre’s (2010) existential philosophy about choice and authenticity and the social theory of Norbert Elias (2000) and Anthony Giddens (1986) the aim is to locate individual freedom and agency within these wider social conditions and through this begin to provide the basis for a broader conception for criminology of power that is both enabling and liberating as well as oppressive and controlling

Reshaping the field: building restorative capital

Restorative justice is best known as an alternative approach for dealing with crime and wrongdoing. Yet as the restorative movement has grown it is increasingly being deployed in different arenas. Based on a two-year study funded by the UK National Lottery, this article provides an early glimpse into how people experience the introduction of restorativeness as cultural change within an organisational context. Using a combination of observation, in-depth interviews and focus groups, this research explores how different staff groups react to, adapt to and resist the introduction of a new ethos and language within their organisation. Drawing on the ideas of Bourdieu (1986), it appears that a new form of restorative cultural capital is emerging that threatens the very integrity of the values restorative justice claims to uphold

Constraining cometary ejection models from meteor storm observations

Modelling and observations of the Leonids have shown that maxima in the meteor storm activity can be identified as due to particles released from the comet during certain perihelion passages. If the particles originating from a certain perihelion passage can be identified, the next obvious question to ask is what information can be gained about the ejection process of particles from a cometary nucleus. We have developed a method to calculate the set of all possible dust trajectories that reach the Earth at some given time. The method involves numerical integration of a few dust particles only and is applied to the Leonid activity in the year 2000. We show that particles of different sizes entering the Earth's atmosphere at the same time were released from the comet at different heliocentric distances. Therefore one has to make assumptions about the activity of the comet with heliocentric distance in order to derive the cometary mass distribution from an observed meteor mass distribution. However, we outline how lower limits on the ejection velocity of the observed particles can be derived
