Continuity and Change in the European Union’s Approach to Enlargement::Turkey and Central and Eastern Europe compared

Existing studies of European Union (EU) enlargement provide few answers to questions concerning continuity and change in the dynamics of the process. This article identifies a number of conditioning factors that have shaped the EU’s approach to eastern enlargement and traces elements of continuity and change in the EU’s handling of Turkey’s membership aspirations. The article focuses on three established factors – member state preferences, supranational activism and EU capacity – and two less prominent factors – public opinion and narrative frame

Presentism and ontological symmetry

In this paper, I argue that there is an inconsistency between two presentist doctrines: that of ontological symmetry and asymmetry of fixity. The former refers to the presentist belief that the past and future are equally unreal. The latter refers to the A-Theoretic intuition that the past is closed or actual, and the future is open or potential. My position in this paper is that the presentist is unable to account for the temporal asymmetry that is so fundamentally a part of her theory. In Section I, I briefly outline a recent defence of presentism due to Craig, and argue that a flaw in this defence highlights the tension between the presentist's doctrines of ontological symmetry and asymmetry of fixity. In Section II, I undertake an investigation, on the presentist's behalf, in order to determine whether she is capable of reconciling these two doctrines. In the course of the investigation, I consider different asymmetries, other than that of ontology, which might be said fundamentally to constitute temporal asymmetry, and the asymmetry of fixity in particular. In Section III, I also consider whether the presentist is able to avail herself of some of the standard B-Theoretic accounts of the asymmetry of fixity, and argue that she cannot. Finally, I conclude that temporal asymmetry cannot be accounted for (or explained) other than through the postulation of an ontological asymmetry.

School Ethos and Governor Relationships

This paper argues that an understanding of ethos is essential for appreciating the process of policy implementation in schools. Whilst educational literature consistently refers to the importance of ethos as a means of understanding the distinctive nature of schools, there is little exploration of school ethos as an effective mediator of policy. Drawing on qualitative data collected in three primary schools it will be demonstrated how ethos can act as a bridge or a barrier to the successful construction of the model of collaborative relationships between school governors and heads, as set out by the education reform legislation of the late 1980s

Local differences, perceptions and IB claimants: implications for policy delivery

Geographical unevenness in labour market and social conditions is one reason why the 'local' has been emphasised increasingly in the delivery of labour market policy in the UK. This article explores the extent to which there are local differences in labour market conditions using the characteristics and experiences of Incapacity Benefit (IB) claimants in Northern Ireland as an example. It then offers some comments on the potential for policy initiatives to cope with these spatial variations. Evidence from a survey of 803 IB claimants is used, supplemented by focus group material derived from discussions with Personal Advisers (PAs). The article shows that whilst there are important variations between areas, largely in the quantity and quality of jobs, and the perceptions that IB claimants hold of their local labour markets, there are also similarities in the general types of labour market barriers they face across areas. There is some evidence, however, to conclude that these barriers in urban areas are particularly pronounced and that some IB claimants in these places face severer obstacles to re-integration in the labour market than those in rural areas. The article also suggests that policy delivery to cope with these geographical differences faces two problems. First, capacity to respond to local differences is limited by strong systemic impulses towards centralisation. Secondly, and paradoxically, local differences erode capacity to respond to severer urban problems because social/institutional capacity within providers and policy-deliverers in these places is limited by high staff turnover and a crowded institutional landscape.

A numerical investigation of the flow structures and losses for turbulent flow in 90 degrees elbow bends

Computational fluid dynamic modelling was carried out on a series of pipe bends having R/r values of 1.3, 5, and 20, with the purpose of determining the accuracy of numerical models in predicting pressure loss data from which to inform one-dimensional loss models. Four separate turbulence models were studied: the standard k-epsilon model, realizable k-epsilon model, k-omega model, and a Reynolds stress model (RSM). The results are presented for each bend in the form of upstream and downstream pressure profiles, pressure distributions along the inner and outer walls, detailed pressure and velocity fields as well as overall loss values. In each case, measured data were presented to evaluate the predictive ability of each model. The RSM was found to perform the best, producing accurate pressure loss data for bends with R/r values of 5 and 20. For the tightest bend with an R/r value of 1.3, however, predictions were significantly worse due to the presence of flow separation, stronger pressure gradients, and high streamline curvature.

Bachowskie przebudzenie Mozarta - studium kontekstu.

In Mozart Studies, it is widely acknowledged that Bach's influence is an important factor for Mozart's artistic development. Yet when discussing how Bach's music affected the development of his compositional styles and techniques, one realizes how tenuous it has been to advance one's arguments without actually seeing in detail how Mozart engaged with Bach’s music. This paper examines what Mozart may have thought when he edited Bach’s fugues for string quartet by attempting to clarify not only what he did and did not do, but also why he did or did not do something, so as to gain some fresh insight into his Bach experience in 1782. It then outlines a more general background of Bach’s fugues in Vienna before they reached the hand of Mozart in order to distinguish what he saw and did to Bach’s fugues.

Stimulation of phosphate uptake and polyphosphate accumulation by activated sludge microorganisms in response to sulfite addition

Enhanced phosphate removal from wastewaters is dependent on the synthesis and intracellular accumulation of polyphosphate by sludge microorganisms. However the role played by polyphosphate in microbial metabolism and the factors that trigger its formation remain poorly-understood. Many examples of the accumulation of the biopolymer by environmental microorganisms are documented; these include a recent report of the presence of large polyphosphate inclusions in sulfur-oxidizing marine bacteria. To investigate whether any link might exist outside the marine environment between the presence of reduced sulfur compounds and enhanced levels of microbial phosphate uptake and polyphosphate accumulation, activated sludge cultures were grown under laboratory conditions in media that contained sulfite, thiosulfate, hydrosulfite or tetrathionate. Only in the presence of sulfite was there any evidence of a stimulatory effect; in medium that contained 0.5 mM sodium sulfite some 17% more phosphate was removed by the sludge, whilst there was an almost two-fold increase in intracellular polyphosphate levels. No indications of sulfite toxicity were observed.

How to estimate scavenger fish abundance using baited camera data

Baited cameras are often used for abundance estimation wherever alternative techniques are precluded, e.g. in abyssal systems and areas such as reefs. This method has thus far used models of the arrival process that are deterministic and, therefore, permit no estimate of precision.
Furthermore, errors due to multiple counting of fish and missing those not seen by the camera have restricted the technique to using only the time of first arrival, leaving a lot of data redundant. Here, we reformulate the arrival process using a stochastic model, which allows the precision of abundance
estimates to be quantified. Assuming a non-gregarious, cross-current-scavenging fish, we show that prediction of abundance from first arrival time is extremely uncertain. Using example data, we show
that simple regression-based prediction from the initial (rising) slope of numbers at the bait gives good precision, accepting certain assumptions. The most precise abundance estimates were obtained
by including the declining phase of the time series, using a simple model of departures, and taking account of scavengers beyond the camera’s view, using a hidden Markov model.
