Sustainable food? Teikei, co-operatives and food citizenship in Japan and the UK

This paper explores in particular how Teikei groups, as forms of Community Supported Agriculture (CSA), operate in Japan, focussing on one particular group. The paper links the Teikei approach to debates around social capital and consumer-citizenship, arguing that pre-existing consumer/citizen institutions may usefully be engaged in developing food citizenship and CSA operations. The discussion is linked to CSA and various other alternative food networks (AFNs) that have grown up in various forms in Japan, the US, the UK and elsewhere in Europe over the past thirty years or so. CSA in similar fashion to Teikei involves bringing producers and consumers closer together in terms of reconnecting the agricultural producer and consumer to aid food traceability and quality (including organic). CSA also exhibits elements of new assemblies of agricultural governance based on enhanced consumer-citizenship where consumers, to varying degrees, have a say in what and how produce is grown and how the land is managed.

Are the debates on water privatization missing the point? Experiences from Africa, Asia and Latin America

This paper has two principal aims: first, to unravel some of the arguments mobilized in the controversial privatization debate, and second, to review the scale and nature of private sector provision of water and sanitation in Africa, Asia and Latin America. Despite being vigorously promoted in the policy arena and having been implemented in several countries in the South in the 1990s, privatization has achieved neither the scale nor benefits anticipated. In particular, the paper is pessimistic about the role that privatization can play in achieving the Millennium Development Goals of halving the number of people without access to water and sanitation by 2015. This is not because of some inherent contradiction between private profits and the public good, but because neither publicly nor privately operated utilities are well suited to serving the majority of low-income households with inadequate water and sanitation, and because many of the barriers to service provision in poor settlements can persist whether water and sanitation utilities are publicly or privately operated. This is not to say that well-governed localities should not choose to involve private companies in water and sanitation provision, but it does imply that there is no justification for international agencies and agreements to actively promote greater private sector participation on the grounds that it can significantly reduce deficiencies in water and sanitation services in the South.

School effectiveness: new managerialism, quality and the Japanisation of education

School effectiveness is a microtechnology of change. It is a relay device, which transfers macro policy into everyday processes and priorities in schools. It is part of the growing apparatus of performance evaluation. Change is brought about by a focus on the school as a site-based system to be managed. There has been corporate restructuring in response to the changing political economy of education. There are now new work regimes and radical changes in organizational cultures. Education, like other public services, is now characterized by a range of structural realignments, new relationships between purchasers and providers and new coalitions between management and politics. In this article, we will argue that the school effectiveness movement is an example of new managerialism in education. It is part of an ideological and technological process to industrialize educational productivity. That is to say, the emphasis on standards and standardization is evocative of production regimes drawn from industry. There is a belief that education, like other public services can be managed to ensure optimal outputs and zero defects in the educational product.

A meta analysis of real estate fund performance

This paper provides evidence regarding the risk-adjusted performance of 19 UK real estate funds in the UK, over the period 1991-2001. Using Jensen’s alpha the results are generally favourable towards the hypothesis that real estate fund managers showed superior risk-adjusted performance over this period. However, using three widely known parametric statistical procedures to jointly test for timing and selection ability the results are less conclusive. The paper then utilises the meta-analysis technique to further examine the regression results in an attempt to estimate the proportion of variation in results attributable to sampling error. The meta-analysis results reveal strong evidence, across all models, that the variation in findings is real and may not be attributed to sampling error. Thus, the meta-analysis results provide strong evidence that on average the sample of real estate funds analysed in this study delivered significant risk-adjusted performance over this period. The meta-analysis for the three timing and selection models strongly indicating that this out performance of the benchmark resulted from superior selection ability, while the evidence for the ability of real estate fund managers to time the market is at best weak. Thus, we can say that although real estate fund managers are unable to outperform a passive buy and hold strategy through timing, they are able to improve their risk-adjusted performance through selection ability.

Asset allocation, cross-class correlation and the structure of property returns

Practical applications of portfolio optimisation tend to proceed on a “top down” basis where funds are allocated first at asset class level (between, say, bonds, cash, equities and real estate) and then, progressively, at sub-class level (within property to sectors, office, retail, industrial for example). While there are organisational benefits from such an approach, it can potentially lead to sub-optimal allocations when compared to a “global” or “side-by-side” optimisation. This will occur where there are correlations between sub-classes across the asset divide that are masked in aggregation – between, for instance, City offices and the performance of financial services stocks. This paper explores such sub-class linkages using UK monthly stock and property data. Exploratory analysis using clustering procedures and factor analysis suggests that property performance and equity performance are distinctive: there is little persuasive evidence of contemporaneous or lagged sub-class linkages. Formal tests of the equivalence of optimised portfolios using top-down and global approaches failed to demonstrate significant differences, whether or not allocations were constrained. While the results may be a function of measurement of market returns, it is those returns that are used to assess fund performance. Accordingly, the treatment of real estate as a distinct asset class with diversification potential seems justified.

Fuzzy analysis: a vague way of dealing with uncertainty in real estate analysis?

Risk and uncertainty are, to say the least, poorly considered by most individuals involved in real estate analysis - in both development and investment appraisal. Surveyors continue to express 'uncertainty' about the value (risk) of using relatively objective methods of analysis to account for these factors. These methods attempt to identify the risk elements more explicitly. Conventionally this is done by deriving probability distributions for the uncontrolled variables in the system. A suggested 'new' way of "being able to express our uncertainty or slight vagueness about some of the qualitative judgements and not entirely certain data required in the course of the problem..." uses the application of fuzzy logic. This paper discusses and demonstrates the terminology and methodology of fuzzy analysis. In particular it attempts a comparison of the procedures with those used in 'conventional' risk analysis approaches and critically investigates whether a fuzzy approach offers an alternative to the use of probability based analysis for dealing with aspects of risk and uncertainty in real estate analysis

Access to the countryside of England and Wales: popular leisure; commodified culture

Risk and uncertainty are, to say the least, poorly considered by most individuals involved in real estate analysis - in both development and investment appraisal. Surveyors continue to express 'uncertainty' about the value (risk) of using relatively objective methods of analysis to account for these factors. These methods attempt to identify the risk elements more explicitly. Conventionally this is done by deriving probability distributions for the uncontrolled variables in the system. A suggested 'new' way of "being able to express our uncertainty or slight vagueness about some of the qualitative judgements and not From its modern origins, associated with the urbanising effect of industrialisation, walking has remained a popular form of outdoor recreation. It has, furthermore, remained an important site of class struggle, with the 'landless' seeking to establish their moral 'citizen' right to roam over open country in contradistinction to the 'landed', who have successfully limited this right to legally-defined public rights of way. In the face of declining farm incomes, however, farmers and landowners have, apparently, modified their attitudes towards public access, but only in return for compensation and management payments under grant schemes such as Countryside Stewardship and the Countryside Premium Scheme. With the Ministry of Agriculture, Fisheries and Food now seeking to extend paid access arrangements to other grant schemes, as part of its response to the European Union's Agri-Environment Regulations, access 'rights' are assuming an increasingly commodified form, thereby questioning, if not undermining, the former citizen claims. For rather than being a benefit of citizenship, the existence of limited, often poorly maintained and inadequately signposted, public rights of way has tied inextricably the extension of legally-enforceable access to the needs of the landowners and farmers. At a time of falling prosperity in agriculture, therefore, they have now exercised their discretion by annexing the populism of consumer culture to reproduce the bourgeois liberal values of the market as a principal determinant of the extension of citizen rights of access to the countryside.

Are normative properties descriptive properties?

Some philosophers think that normative properties are identical to descriptive properties. In this paper, I argue that this entails that it is possible to say which descriptive properties normative properties are identical to. I argue that Frank Jackson’s argument to show that this is possible fails, and that the objections to this argument show that it is impossible to say which descriptive properties normative properties are identical to. I conclude that normative properties are not identical to descriptive properties. I then show that if we combine this conclusion with the conclusion of a different argument that Jackson has given to show that there are no irreducibly normative properties, it follows that there are no normative properties at all.

The asymptotic behavior of densities related to the supremum of a stable process

If X is a stable process of index α∈(0, 2) whose Lévy measure has density cx−α−1 on (0, ∞), and S1=sup0x)∽Aα−1x−α as x→∞ and P(S1≤x)∽Bα−1ρ−1xαρ as x↓0. [Here ρ=P(X1>0) and A and B are known constants.] It is also known that S1 has a continuous density, m say. The main point of this note is to show that m(x)∽Ax−(α+1) as x→∞ and m(x)∽Bxαρ−1 as x↓0. Similar results are obtained for related densities.

Predicting outliers in ensemble forecasts

An ensemble forecast is a collection of runs of a numerical dynamical model, initialized with perturbed initial conditions. In modern weather prediction for example, ensembles are used to retrieve probabilistic information about future weather conditions. In this contribution, we are concerned with ensemble forecasts of a scalar quantity (say, the temperature at a specific location). We consider the event that the verification is smaller than the smallest, or larger than the largest ensemble member. We call these events outliers. If a K-member ensemble accurately reflected the variability of the verification, outliers should occur with a base rate of 2/(K + 1). In operational forecast ensembles though, this frequency is often found to be higher. We study the predictability of outliers and find that, exploiting information available from the ensemble, forecast probabilities for outlier events can be calculated which are more skilful than the unconditional base rate. We prove this analytically for statistically consistent forecast ensembles. Further, the analytical results are compared to the predictability of outliers in an operational forecast ensemble by means of model output statistics. We find the analytical and empirical results to agree both qualitatively and quantitatively.

Chaucer's presence in songes and sonettes

In an elegy to Wyatt published in Tottel’s Miscellany, Surrey claims that Wyatt ‘reft Chaucer the glory of his wit’. This statement, which both lauds and resists Chaucer, is a microcosm of the way Chaucer is treated throughout the Miscellany. In examining the collection’s paradoxical attitude to Chaucer, this essay focuses particularly on the Squire’s Tale, the Franklin’s Tale, Anelida and Arcite, the Legend of Good Women, and several short lyrics. In its interest in courtly love poetry and Petrarch, the Miscellany follows a trajectory in English poetry set by Chaucer. Its courtly verse is saturated with words, phrases, and tropes from his poetry. Rhyme royal, which he introduced into English poetry, is widely used. The Canterbury Tales has been fully assimilated and can be referred to allusively with the same confidence of the audience’s knowledge as is the case when referring to classical myth; in Wyatt’s ‘Myne owne Jhon Poins’, the speaker, disclaiming deceitfulness, says that he cannot ‘say that Pan/ Passeth Appollo in musike manifold:/ Praise syr Topas for a noble tale,/ And scorne the story that the knight tolde’ (lines 48-50). However, Chaucer’s poetry is also downplayed and contested in the Miscellany. ‘Truth’, the only poem of his which appears in the volume, is disingenuously placed in the ‘Uncertain Authors’ section. In addition, some of the most important elements of his work are strongly resisted in the Miscellany, either ignored, dismissed or challenged. These elements include Chaucer’s interest in variety of voice, his sympathetic engagement with women, particularly wronged women, and his interest in female speech and particularly female complaint. The Miscellany, by contrast, is dominated by male-voiced lyrics preoccupied with the pain inflicted on the lover by a lady who is frequently unfeeling, cruel, or faithless. Chaucer’s frequent focus on the cynical seduction and betrayal of female by male is reversed in the Miscellany, and the language and metaphors he uses to express male cruelty (e.g. the word ‘newfangleness’ and images of hooks, nets and traps) are usurped to describe the lady’s cruelty to the suffering lover. On occasion, poems in the Miscellany challenge specific Chaucerian texts; ‘On His Love Named White’ throws down a gauntlet to The Book of the Duchess, while two of Surrey’s poems implicitly take issue with the female falcon’s voice in the Squire’s Tale, giving the deceitful tercelet the opportunity to shout down the falcon’s charges. The essay thus shows that in many respects Tottel’s Miscellany is only superficially Chaucerian, and that it both passively and actively takes issue with Chaucer’s work.

Rumo a uma definição positiva de world cinema

However common it has become, the term World Cinema still lacks a proper, positive definition. Despite its all-encompassing, democratic vocation, it is not usually employed to mean cinema worldwide. On the contrary, the usual way of defining it is restrictive and negative, as ‘the non-Hollywood cinema’. Needless to say, negation here translates a positive intention to turn difference from the dominant model into a virtue to be rescued from an unequal competition. However, it unwittingly sanctions the American way of looking at the world, according to which Hollywood is the centre and all other cinemas are the periphery. As an alternative to this model, this chapter proposes: • World Cinema is simply the cinema of the world. It has no centre. It is not the other, but it is us. It has no beginning and no end, but is a global process. World Cinema, as the world itself, is circulation. • World Cinema is not a discipline, but a method, a way of cutting across film history according to waves of relevant films and movements, thus creating flexible geographies. • As a positive, inclusive, democratic concept, World Cinema allows all sorts of theoretical approaches, provided they are not based on the binary perspective.

On the stability and convergence of the finite section method for integral equation formulations of rough surface scattering

We consider the Dirichlet and Robin boundary value problems for the Helmholtz equation in a non-locally perturbed half-plane, modelling time harmonic acoustic scattering of an incident field by, respectively, sound-soft and impedance infinite rough surfaces.Recently proposed novel boundary integral equation formulations of these problems are discussed. It is usual in practical computations to truncate the infinite rough surface, solving a boundary integral equation on a finite section of the boundary, of length 2A, say. In the case of surfaces of small amplitude and slope we prove the stability and convergence as A→∞ of this approximation procedure. For surfaces of arbitrarily large amplitude and/or surface slope we prove stability and convergence of a modified finite section procedure in which the truncated boundary is ‘flattened’ in finite neighbourhoods of its two endpoints.

Star/poverty space: the making of the ‘development celebrity’

What is it that gives celebrities the voice and authority to do and say the things they do in the realm of development politics? Asked another way, how is celebrity practised and, simultaneously, how does this praxis make celebrity, personas, politics and, indeed, celebrities themselves? In this article, we explore this ‘celebrity praxis’ through the lens of the creation of the contemporary ‘development celebrity’ in those stars working for development writ large in the so-called Third World. Drawing on work in science studies, material cultures and the growing geo-socio-anthropologies of things, the key to understanding the material practices embedded in and creating development celebrity networks is the multiple and complex circulations of the everyday and bespectacled artefacts of celebrity. Conceptualised as the ‘celebrity–consumption–compassion complex’, the performances of development celebrities are as much about everyday events, materials, technologies, emotions and consumer acts as they are about the mediated and liquidised constructions of the stars who now ‘market’ development.Moreover, this complex is constructed by and constructs what we are calling ‘star/poverty space’ that works to facilitate the ‘expertise’ and ‘authenticity’ and, thus, elevated voice and authority, of development celebrities through poverty tours, photoshoots, textual and visual diaries, websites and tweets. In short, the creation of star/poverty space is performed through a kind of ‘materiality of authenticity’ that is at the centre of the networks of development celebrity. The article concludes with several brief observations about the politics, possibilities and problematics of development celebrities and the star/poverty spaces that they create.

Aircraft routing with minimal climate impact: the REACT4C climate cost function modelling approach (V1.0)

In addition to CO2, the climate impact of aviation is strongly influenced by non-CO2 emissions, such as nitrogen oxides, influencing ozone and methane, and water vapour, which can lead to the formation of persistent contrails in ice-supersaturated regions. Because these non-CO2 emission effects are characterised by a short lifetime, their climate impact largely depends on emission location and time; that is to say, emissions in certain locations (or times) can lead to a greater climate impact (even on the global average) than the same emission in other locations (or times). Avoiding these climate-sensitive regions might thus be beneficial to climate. Here, we describe a modelling chain for investigating this climate impact mitigation option. This modelling chain forms a multi-step modelling approach, starting with the simulation of the fate of emissions released at a certain location and time (time-region grid points). This is performed with the chemistry–climate model EMAC, extended via the two submodels AIRTRAC (V1.0) and CONTRAIL (V1.0), which describe the contribution of emissions to the composition of the atmosphere and to contrail formation, respectively. The impact of emissions from the large number of time-region grid points is efficiently calculated by applying a Lagrangian scheme. EMAC also includes the calculation of radiative impacts, which are, in a second step, the input to climate metric formulas describing the global climate impact of the emission at each time-region grid point. The result of the modelling chain comprises a four-dimensional data set in space and time, which we call climate cost functions and which describes the global climate impact of an emission at each grid point and each point in time. In a third step, these climate cost functions are used in an air traffic simulator (SAAM) coupled to an emission tool (AEM) to optimise aircraft trajectories for the North Atlantic region. Here, we describe the details of this new modelling approach and show some example results. A number of sensitivity analyses are performed to motivate the settings of individual parameters. A stepwise sanity check of the results of the modelling chain is undertaken to demonstrate the plausibility of the climate cost functions.
