Exploring the Zionist evolution of Robert Briscoe: History and memory

Robert Briscoe was the Dublin born son of Lithuanian and German-Jewish immigrants. As a young man he joined Sinn Féin and was an important figure in the War of Independence due to a role as one of the IRA’s main gun-procuring agents. He took the anti-Treaty side during an internecine Civil War, mainly due to the influence of Eamon de Valera and retained a filial devotion towards him for the rest of his life. In 1926 he was a founding member of Fianna Fáil, de Valera’s breakaway republican party, which would dominate twentieth-century Irish politics. He was first elected as a Fianna Fáil T.D. (Teachta Dála, Deputy to the Dáil) in 1927, and successfully defended his seat eleven times becoming the first Jewish Lord Mayor of Dublin in 1956, an honour that was repeated in 1961. On this basis alone, it can be argued that Briscoe was a significant presence in an embryonic Irish political culture; however, when his role in the 1930s Jewish immigration endeavor is acknowledged, it is clear that he played a unique part in one of the most contentious political and social discourses of the pre-war years. This was reinforced when Briscoe embraced Zionism in a belated realisation that the survival of his European co-religionists could only be guaranteed if an independent Jewish state existed. This information is to a certain degree public knowledge; however, the full extent of his involvement as an immigration advocate for potential Jewish refugees, and the seniority he achieved in the New Zionist Organisation (Revisionists) has not been fully recognised. This is partly explicable because researchers have based their assessment of Briscoe on an incomplete political archive in the National Library of Ireland (NLI). The vast majority of documentation pertaining to his involvement in the immigration endeavor has not been available to scholars and remains the private property of Robert Briscoe’s son, Ben Briscoe. The lack of immigration files in the NLI was reinforced by the fact that information about Briscoe’s Revisionist engagement was donated to the Jabotinsky Institute in Tel Aviv and can only be accessed physically by visiting Israel. Therefore, even though these twin endeavors have been commented on by a number of academics, their assessments have tended to be based on an incomplete archive, which was supplemented by Briscoe’s autobiographical memoir published in 1958. This study will attempt to fill in the missing gaps in Briscoe’s complex political narrative by incorporating the rarely used private papers of Robert Briscoe, and the difficult to access Briscoe files in Tel Aviv. This undertaking was only possible when Mr.Ben Briscoe graciously granted me full and unrestricted access to his father’s papers, and after a month-long research trip to the Jabotinsky Institute in Tel Aviv. Access to this rarely used documentation facilitated a holistic examination of Briscoe’s complex and multifaceted political reality. It revealed the full extent of Briscoe’s political and social evolution as the Nazi instigated Jewish emigration crisis reached catastrophic proportions. He was by turn Fianna Fáil nationalist, Jewish immigration advocate and senior Revisionist actor on a global stage. The study will examine the contrasting political and social forces that initiated each stage of Briscoe’s Zionist awakening, and in the process will fill a major gap in Irish-Jewish historiography by revealing the full extent of his Revisionist engagement.

Spank performance tour [at National Review of Live Art 2008]

Spank is a duet about two women’s journeys as they play out different roles. One woman recalls stinging anecdotes marked by intimacy, jealousy, fear and fantasy from her childhood in the 70s suburbs – round the corner from where Mike Leigh would film Life Is Sweet. Her Double (projected on screen) reads from a newspaper about an event that punctured the local community, creating an enduring cultural scar, her voice lacking emotion. Both women must eventually face one another and ask, who is deceiving whom? The consequences of guilt and shame and the unstable shift from private memory to public consequence is inevitable and deadly.[ABSTRACT BY THE AUTHOR]

Hierarchical random walks in trace fossils and the origin of optimal search behavior

Efficient searching is crucial for timely location of food and other resources. Recent studies show diverse living animals employ a theoretically optimal scale-free random search for sparse resources known as a Lévy walk, but little is known of the origins and evolution of foraging behaviour and the search strategies of extinct organisms. Here we show using simulations of self-avoiding trace fossil trails that randomly introduced strophotaxis (U-turns) – initiated by obstructions such as ¬¬¬self-trail avoidance or innate cueing – leads to random looping patterns with clustering across increasing scales that is consistent with the presence of Lévy walks. This predicts optimal Lévy searches can emerge from simple behaviours observed in fossil trails. We then analysed fossilized trails of benthic marine organisms using a novel path analysis technique and find the first evidence of Lévy-like search strategies in extinct animals. Our results show that simple search behaviours of extinct animals in heterogeneous environments give rise to hierarchically nested Brownian walk clusters that converge to optimal Lévy patterns. Primary productivity collapse and large-scale food scarcity characterising mass extinctions evident in the fossil record may have triggered adaptation of optimal Lévy-like searches. The findings suggest Lévy-like behaviour has been employed by foragers since at least the Eocene but may have a more ancient origin, which could explain recent widespread observations of such patterns among modern taxa.

Molecular cloning of the helokinestatin/CNP precursor from a venom-derived cDNA library of the Mexican beaded lizard, Heloderma horridum, and identification of a novel encoded bradykinin-antagonist peptide, helokinestatin-6

Helokinestatins 1–5 represent a novel family of bradykinin antagonist peptides originally isolated from the venom of the Gila Monster, Heloderma suspectum. We found that they were encoded in tandem along with a single copy of C-type natriuretic peptide (CNP), by two different but almost identical biosynthetic precursors that were cloned from a venom-derived cDNA library. Here we have applied the same strategy to the venom of a related species, the Mexican beaded lizard, Heloderma horridum. Lyophilised venom was used as a surrogate tissue to generate a cDNA library that was interrogated with primers from the previous study and for reverse phase HPLC fractionation. The structure of a single helokinestatin precursor was obtained following sequencing of 20 different clones. The open-reading frame contained 196 amino acid residues, somewhat greater than the 177–178 residues of the corresponding helokinestatin precursors in H. suspectum. The reason for this difference in size was the insertion of an additional domain of 18 amino acid residues encoding an additional copy of helokinestatin-3. Helokinestatin-6 (GPPFNPPPFVDYEPR) was a novel peptide from this precursor identified in venom HPLC fractions. A synthetic replicate of this peptide antagonised the relaxation effect of bradykinin on rat arterial smooth muscle. The novel peptide family, the helokinestatins, have been shown to be present in the venom of H. horridum and to be encoded by a single precursor of different structure to those from H. suspectum. Studies such as this reveal the naturally-selected structures of bioactive peptides that have been optimised for purpose and provide the scientist with a natural analogue library for pharmacological investigation.

Construction of cDNA libraries from trifluoroacetic acid-solvated amphibian skin secretions: molecular cloning of multiple bombinin-like peptide precursor transcripts from a library of yellow-bellied toad (Bombina variegata) secretion

Amphibian skin secretions are renowned as complex mixtures of bioactive peptides many of which are analogues of endogenous regulatory peptides. While skin secretions can be obtained non-invasively for peptidome analysis, parallel studies on the granular gland transcriptome required specimen sacrifice. The aim of the present study was to analyse archived skin secretions to determine the robustness of bioactive peptide precursor-encoding polyadenylated mRNAs in an attempt to extract maximum molecular information from rare samples. A range of solvated skin secretion samples were examined after lyophilisation for their potential to generate viable and comprehensive cDNA libraries based upon polyadenylated mRNA capture and amplification/cloning using appropriate commercial kits. Here we present unequivocal data that the granular gland transcriptome persists in a PCR amenable format even after storage for as long as 12 years in 0.1%(v/v) aqueous trifluoroacetic acid (TFA). We used a pooled skin secretion sample (2 ml) from the yellow-bellied toad, Bombina variegata (n = 14), containing the equivalent of 5 mg/ml of lyophilised skin secretion, that had been used in part for peptide isolation purposes in 1998 and had been stored at - 20 °C since that time. In the first cloning experiment, 12 different bombinin-like peptide precursor cDNAs were cloned encoding 17 different bombinins, the majority of which were novel. Subsequently, bombesin and bradykinin-related peptide precursor transcripts have been cloned successfully. These data illustrate the unexpected stability/longevity of the transcriptome in these secretions — a finding with implications for both this field of research and for the wider field of molecular biology.
