An NMR study on internal browning in pears

Internal browning in pears (Pyrus communis L. cv. Blanquilla) has been studied by NMR and MRI in order to develop a non-destructive procedure for on-line disorder identification. For NMR relaxometry, disordered tissue shows higher transverse relaxation rates compared to sound tissue, especially at higher magnetic field strength and for long pulse spacing. Membrane alteration and therefore tissue disintegration, as well as water evaporation, appear to be the main causes of this response. Correlation between relaxation times and diffusion showed that the proton pools in disordered tissue are grouped into a smaller number of populations compared to sound tissue, also highlighting cell decompartmentation in disordered tissue. At a macroscopic level, fast low angle shot MR images, effective transverse relaxation-weighted (TR 11 ms and TE 3.7 ms) and proton density-weighted (TR 7.6 ms and TE 2.5 ms), were acquired for pears at a rate of 54 mm/s. Images have been discriminated for internal breakdown according to histogram characteristics. Up to 94 and 96% of pears, respectively, were correctly classified in the former and the latter type of images. In this study a minimum value of 12% of tissue affected by breakdown was always clearly identifie

Indeterminacy and Architectural History: Deterritorializing Cosimo Fanzago

This article is a critique of architectural history’s tendency to overdetermine in thinking about practice and theory in general, and in thinking the relationship between architecture and spirituality in post-Tridentine ecclesiastical architecture in particular. It first demonstrates what is meant both by over-determination and resistance to interdisciplinarity within mainstream architectural history before critically exploring in relation to this how post-Tridentine architecture and spiritual life or religious devotion might be thought together, the sorts of relationships between the two that may be thought to take place, and asks where this relationship might be located. Suggesting that it might be profitable to follow Deleuze’s philosophy of the Baroque in refusing the tripartite division between a field of reality (the world) and a field of representation (in his case the book, in ours, architecture) and a field of subjectivity (the author, the architect), and rather to adopt like him, the notion of rhizome — without beginning or end, always in the middle, between things, interbeing, intermezzo, indeterminate. The article seeks to consider Baroque architecture as rhizomatic construction, rather than the usual (and unhelpful) preoccupations with it as dichotomous, expressive, or ‘propagandistic’

Behavioral Phenomena and Population Estimation of White-Tailed Deer Based on Camera Trap Data

When shaping management actions and conservation programs, it is essential to understand the population dynamics of a species. One species that sees extensive management and research effort is the white-tailed deer (Odocoileus virginianus), as it is both ecologically and recreationally important in many places. Although there are a multitude of ways to study and estimate the population dynamics of white-tailed deer, one method in particular comes with significant advantages: camera trapping. For this study, nine camera traps were set up at deer scrapes across a private ranch in south Texas. After collecting images during the fall/winter rut of 2015, the cameras’ photos were amassed, and photographed bucks were identified based on unique antler formations. The photo data were then analyzed for a variety of purposes: (a) to determine whether bucks visit scrapes non- randomly; (b) to examine patterns in the ranges of dominant individuals; (c) to assess whether diversity indexes identify fundamental differences in the collections of bucks visiting scrapes. Finally, a novel population estimation technique was applied by adapting and applying the program EstimateS. There were a total of 129 bucks identified over the study region. I determined that bucks did indeed visit camera sites non-randomly and that they visited certain scrapes preferentially. This might have to do with the resources available in specific areas. Additionally, I observed that particular dominant individuals have home ranges that overlap, while others are much more solitary. This suggests that the sites themselves are differentially defensible, and that whether a location is dominated has to do with both the resources it offers and its ability to be monopolized. Results of the population estimation technique suggested that there were a number of bucks that remained undetected by the cameras. Future research could work to ascertain the accuracy of the population estimations made by EstimateS.Integrative Biolog

The Baroque: Beads in a Rosary or Folds in Time

When Benedetto Croce associated the baroque with decadence he was developing a current of critical thinking which had construed the term ‘baroque’ pejoratively since the seventeenth century. This essay explores the idea of a baroque that is neither pejorative nor ‘early modern'’ by outlining the etymology and history of the term ‘baroque’, tracing its chequered history as a term of abuse in the seventeenth and eighteenth centuries, through Benedetto Croce's characterization of the baroque as ‘decadent’, to two radically different ways of interpreting the baroque adopted by Walter Benjamin and Gilles Deleuze. This paper asks whether we might consider the baroque not as decadent, but as antidote to decadence, of baroque as troubling the smooth waters of a linear historicism

From Beveridge to Turner: Demography, Distribution and the Future of Pensions in the UK

This article outlines the recommendations of the UK Pensions Commission, and the data and analysis on which they were based, including projections of demographic change, trends in private pension saving, and evolution of the state pension system. The Commission concluded that without reform, structural problems with UK pensions would lead to increasingly inadequate and inequitable provision in 15-20 years time. It recommended reforms which would lead to a more generous, more universal and less means-tested state system than would otherwise evolve, and the establishment of a low cost National Pension Savings Scheme, into which employees without good employer provision would automatically be enrolled. The proposals, which have now largely been adopted by the UK government, imply eventual increases both in state spending on pensions as a share of national income and in State Pension Age, but accompanied by measures to facilitate later and more flexible retirement.Demographic change, Pensions, Retirement incomes, Social security

Taxation for the Enabling State

This paper takes as its starting point Henry Neuburger's injunction that taxation must be seen as a contribution to the maintenance of the welfare state, not as a dead-weight burden. It sets recent developments in the UK tax ratio in the context of changes in public spending, particularly on welfare services, in the public sector's balance sheet, and the distributional effects of both tax and spending. It then discusses tax and transfer policy since the change of governance in May 1997 in the context of public attitudes to inequality and different forms of redistribution. It compares the distributional effects of the four Labour Budgets since July 1997 with those which would have resulted from simply indexing the April 1997 tax and social security system for income growth. This suggests that actual reforms will on average deliver as much to lower income groups as income indexation would have done, but at lower cost to the public finances, and in a way which is more consistent with public attitudes. However, delays between Budget announcements and implementation meant that inequality and relative poverty increased in Labour's first two years in office. If further progress is to be made towards the target of abolishing child poverty in a generation, the measures so far announced will have to be added to each year.Tax, public spending, inequality, public attitudes, redistribution

Inclusion or Insurance? National Insurance and the future of the contributory principle

This paper examines the decline of National Insurance in Britain, as witnessed by its declining share of all social security spending and the steady dilution of the "contributory principle" on which it was originally based. It argues that this decline is not an accident: under governments of the Left, arguments in favour of inclusion have been predominant, non-contributory benefits expanded and contribution conditions softened; under those of the Right, the emphasis has been on focussing limited resources on the poorest through means-testing. Given where we are now, the strong arguments in principle for social insurance look much weaker. However, there are also reasons why the system has not been swept away, notably the way in which the bulk of the system is concerned with state pension rights which have already accrued. The paper explores current plans for the future development of state pensions, arguing that their combined effect is to restore something like a flat rate state pension, but with significant complexity. This could be developed into a more transparent system guaranteeing a total state pension at a fixed percentage of average earnings for those meeting a participation test, rather than being based on contribution records. This leaves a choice for the remaining sixth of National Insurance benefits: to separate out state pensions and absorb the other insurance benefits within the rest of working age social security, or to maintain the scope of National Insurance, but also based on participation, not past contributions.social insurance, social security, pensions, direct taxation
