Art, Biography, Sexuality: Patrick Procktor and Keith Vaughan
No full textThis critical review forms a reflection on the research published within the following publications:
Patrick Procktor: Art and Life (Unicorn Press, 2010)
Keith Vaughan: The Mature Oils 1946-1977, (Sansom & Co., 2012)
The research is on two artists, Patrick Procktor (1936-2003), and Keith Vaughan (1912-1977). The monograph on Procktor – previously one of the least documented of the generation of artists who came to prominence in London in the Sixties – positions him in a history of art from which he had been notably absent. The research on Vaughan asserts a new reading of his work, one that is both deeper and more nuanced in its analysis of the ways in which personal experience and sexuality are encoded autobiographically within his work. Crucially, in both artists biography and work are symbiotically linked; the research therefore examines the links between life and art.
Revisionary in intent, the work examines trajectories of experience of gay British (or rather, English) artists in the twentieth century, artists who sought to express themselves and forge careers within the constraints of a heteronormative society, albeit one in which attitudes to sexuality were undergoing change. As gay men, both were constrained by the social mores of their times, and each used painting as a means to affirm personal and sexual identities. A key research interest is in the ways in which sexuality and persona are reflected in critical responses to the artist’s work: in Vaughan, Procktor and other gay male artists of the period. The writing on both Procktor and Vaughan examines the relationship between their personal and professional/artistic lives, framed within a broader socio-political and art historical context. It asserts the place of biography as a means to understand and form new readings of the work. The work adds substantially to the literature and wider discourse on post-war British painting and social history
Educational Developmentalists Divided? Patrick Cannon, Patrick Hillery and the Economics of Education in the Early 1960s
No full textThe catalytic effect of the OECD-linked study that produced Investment in Education is a much celebrated episode of Ireland’s modernisation. A remarkably broad cross-departmental consensus supported the initiative. Bureaucratic caution and ministerial self-preservation were set aside to allow a “warts and all” portrait of Irish education to be painted by the study team. Special efforts were made to focus public attention on the findings of a damning report that legitimated a quickening pace of government action to increase access to an expanded, rationalised and reoriented education system. But, as well as developmentalist triumph over conservatism in the education field, there was also significant division between state and civil society developmentalists. This is examined through an analysis of the relationship between the Federation of Lay Catholic Secondary Schools and the Department of Education.
Excavations at Tas-Silg, Malta : a preliminary report on the 1996-1998 campaigns conducted by the Department of Classics and Archaeology of the University of Malta
No full textThe area known as Tas-Silg is situated in the south-eastern part of the island of Malta, close to
Marsaxlokk harbour. In reality the place name refers to the small church
dedicated to Our Lady of the Snows (hence Tas-Silg) situated at the point where the narrow ·
road from Zejtun forks out in two directions: to Delimara and Xrobb il-Ghagin due south-east
and to Marsaxlokk village due south-west. A British-period fort occupying the highest point
of the elongated hill further south along· the first road also carries the same place name. The
lower and more compact hill on which the excavations have been conducted is called 'Ta'
Berikka' , but since it is so close to the above-mentioned church (only 50 m to the north) the
tradition of calling it Tas-Silg is now well established and there is no sense in changing it.
The site has a commanding view of the Marsaxlokk harbour to the south and overlooks two
other bays, Marsascala and St Thomas's bay, to the north-east. On all sides the slope is broken
up by man-made terraced fields
There is no doubt that the topography of the site must have been a determining factor in its
choice for the establishment of a religious centre in the Temple period of Maltese pehistory
(3000--2500 BC), though one must keep in mind that close to Tas-Silg there are three other
prehistoric temple sites. each one with a completely different topography. The Temple people
were quite introverted in their cultural isolation and do not seem to have been much interested
in seafaring and in the outside world. The situation changed radically in the following age, the
Bronze Age. when the island was occupied by people who set up villages on naturally defensible hilltops, occasionally fortifying them with artificial ramparts. The Tas-Silg hill
with its temple ruins was occupied by these people, but it is not as yet clear for what purpose.
The scenario changed again in historical times when the central and western Mediterranean
started to be parcelled out among the commercial powers originating in the eastern
Mediterranean. The Greeks do not seem to have even tried 10 colonize Malta as they did in
neighbouring Sicily. The Phoenicians, however, did occupy the island, apparently through a
slow process of peaceful penetration and eventual political and cultural assimi lation. It was in
this period that the ruins of the megalithic temple were transformed into a Phoenician extraurban
shrine dedicated to Astarte, which in time expanded into a full y-fledged sanctuary with
an international reputation. The last chapter in the millennia- long history of the site was
written when the colonnaded courtyard in front of the old temple was transformed into an
early Christian church. Any use made of the site in the following Arab period is, once again,
poorly understood.peer-reviewe

Hypersuccinct trees - New universal tree source codes for optimal compressed tree data structures and range minima
No full textWe present a new universal source code for distributions of unlabeled binary and ordinal trees that achieves optimal compression to within lower order terms for all tree sources covered by existing universal codes. At the same time, it supports answering many navigational queries on the compressed representation in constant time on the word-RAM; this is not known to be possible for any existing tree compression method. The resulting data structures, “hypersuccinct trees”, hence combine the compression achieved by the best known universal codes with the operation support of the best succinct tree data structures. We apply hypersuccinct trees to obtain a universal compressed data structure for range-minimum queries. It has constant query time and the optimal worst-case space usage of 2n + o(n) bits, but the space drops to 1.736n + o(n) bits on average for random permutations of n elements, and 2 lg (nr ) + o(n) for arrays with r increasing runs, respectively. Both results are optimal; the former answers an open problem of Davoodi et al. (2014) and Golin et al. (2016). Compared to prior work on succinct data structures, we do not have to tailor our data structure to specific applications; hypersuccinct trees automatically adapt to the trees at hand. We show that they simultaneously achieve the optimal space usage to within lower order terms for a wide range of distributions over tree shapes, including: binary search trees (BSTs) generated by insertions in random order/Cartesian trees of random arrays, random fringe-balanced BSTs, binary trees with a given number of binary/unary/leaf nodes, random binary tries generated from memoryless sources, full binary trees, unary paths, as well as uniformly chosen weight-balanced BSTs, AVL trees, and left-leaning red-black trees
Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
Zinc has insulin-mimetic properties which enhance spinal fusion in a rat model
No full textBACKGROUND CONTEXT: Previous studies have found that insulin or insulin-like growth factor treatment can stimulate fracture healing in diabetic and normal animal models, and increase fusion rates in a rat spinal fusion model. Insulin-mimetic agents, such as zinc, have demonstrated antidiabetic effects in animal and human studies, and these agents that mimic the effects of insulin could produce the same beneficial effects on bone regeneration and spinal fusion.
PURPOSE: The purpose of this study was to analyze the effects of locally applied zinc on spinal fusion in a rat model.
STUDY DESIGN/SETTING: Institutional Animal Care and Use Committee-approved animal study using Sprague-Dawley rats was used as the study design.
METHODS: Thirty Sprague-Dawley rats (450-500 g) underwent L4-L5 posterolateral lumbar fusion (PLF). After decortication and application of approximately 0.3 g of autograft per side, one of three pellets were added to each site: high-dose zinc calcium sulfate (ZnCaSO4), low-dose ZnCaSO4 (half of the high dose), or a control palmitic acid pellet (no Zn dose). Systemic blood glucose levels were measured 24 hours postoperatively. Rats were sacrificed after 8 weeks and the PLFs analyzed qualitatively by manual palpation and radiograph review, and quantitatively by micro-computed tomography (CT) analysis of bone volume and trabecular thickness. Statistical analyses with p-values set at .05 were accomplished with analysis of variance, followed by posthoc tests for quantitative data, or Mann-Whitney rank tests for qualitative assessments.
RESULTS: Compared with controls, the low-dose zinc group demonstrated a significantly higher manual palpation grade (p=.011), radiographic score (p=.045), and bone formation on micro-CT (172.9 mm3 vs. 126.7 mm3 for controls) (p3 vs. 126.7 mm3) (p<.01) versus controls, and was trending toward higher manual palpation scores (p=.058).
CONCLUSIONS: This study demonstrates the potential benefit of a locally applied insulin-mimetic agent, such as zinc, in a rat lumbar fusion model. Previous studies have demonstrated the benefits of local insulin application in the same model, and it appears that zinc has similar effects.Peer reviewe
