State and Society in Papua New Guinea, 2001–2021

In a previous volume, State and Society in Papua New Guinea: The First Twenty-Five Years (2001, reprinted by ANU E Press in 2004), a collection of papers by the author published between 1971 and 2001 was put together to mark Papua New Guinea's first 25 years as an independent state. This volume presents a collection of papers written between 2001 and 2021, which update the story of political and social development in Papua New Guinea in the first two decades of the twenty-first century. The chapters cover a range of topics, from an evaluation of proposals for political reform in the early 2000s, a review of the discussion of 'failing states’ in the island Pacific and the shift to limited preferential voting in 2007, to a detailed account of political developments from the move against Sir Michael Somare in 2011 to the election of Prime Minister Marape and his performance to 2022. There are also chapters on language policy, external and internal security, religious fundamentalism and national identity, and the sustainability of economic growth

Papua New Guinea under the O’Neill Government: Has There Been a Shift in Political Style?

In 2011–12 Papua New Guinea suffered its most serious constitutional crisis since independence, when the incumbent prime minister, Grand Chief Sir Michael Somare, was effectively removed from office in a ‘political coup’ by members of parliament whose actions were subsequently ruled unconstitutional by the Supreme Court. The political impasse of this period, in which two people laid claim to the office of prime minister, was finally resolved in mid-2012 following a scheduled national election. But it is arguable that the damage done in 2011 to the institutions of Papua New Guinea’s democratic system was not entirely undone in 2012 and that political developments since 2012 give some cause for concern. This paper briefly recounts the events of 2011–12 and looks at political developments under the O’Neill government which came to power following the 2012 election.Australian Department of Foreign Affairs and Trad

(New) Bulgarian Enlighteners and Ambassadors? The Reinvention of National Identity in Times of Crisis

Drawing on empirical data from 37 Bulgarian students and young professionals in the UK, this article explores the intersection of the discourses produced by the European crises and migrants' national identity. In Bulgaria, the crisis narrative is embedded in the arguably never‐ending democratic transition, manifested in socio‐economic instability and political volatility. Simultaneously, “Brexit Britain” is enveloped in strong Eurosceptic sentiments, propelled by a combination of austerity measures and intensified Eastern European migratory flows. Both contexts subject Bulgarian migrants to stigmatizing representations. Looking at migrants' everyday practices, the data reveals that young Bulgarians draw on the related ideas of the “new” Enlightener and Ambassador to counterbalance negative discourses. Thus, the article explores the meanings and significance attributed to the Enlighteners and the Ambassadors, arguing that the participants engage in “social creativity” and “individual mobility” strategies that lead to reinvention of national identity

Thermostatistics of deformed bosons and fermions

Based on the q-deformed oscillator algebra, we study the behavior of the mean occupation number and its analogies with intermediate statistics and we obtain an expression in terms of an infinite continued fraction, thus clarifying successive approximations. In this framework, we study the thermostatistics of q-deformed bosons and fermions and show that thermodynamics can be built on the formalism of q-calculus. The entire structure of thermodynamics is preserved if ordinary derivatives are replaced by the use of an appropriate Jackson derivative and q-integral. Moreover, we derive the most important thermodynamic functions and we study the q-boson and q-fermion ideal gas in the thermodynamic limit.Comment: 14 pages, 2 figure

15-keto-prostaglandin E2 activates host peroxisome proliferator-activated receptor gamma (PPAR-γ) to promote Cryptococcus neoformans growth during infection

Cryptococcus neoformans is one of the leading causes of invasive fungal infection in humans worldwide. C. neoformans uses macrophages as a proliferative niche to increase infective burden and avoid immune surveillance. However, the specific mechanisms by which C. neoformans manipulates host immunity to promote its growth during infection remain ill-defined. Here we demonstrate that eicosanoid lipid mediators manipulated and/or produced by C. neoformans play a key role in regulating pathogenesis. C. neoformans is known to secrete several eicosanoids that are highly similar to those found in vertebrate hosts. Using eicosanoid deficient cryptococcal mutants Δplb1 and Δlac1, we demonstrate that prostaglandin E2 is required by C. neoformans for proliferation within macrophages and in vivo during infection. Genetic and pharmacological disruption of host PGE2 synthesis is not required for promotion of cryptococcal growth by eicosanoid production. We find that PGE2 must be dehydrogenated into 15-keto-PGE2 to promote fungal growth, a finding that implicated the host nuclear receptor PPAR-γ. C. neoformans infection of macrophages activates host PPAR-γ and its inhibition is sufficient to abrogate the effect of 15-keto-PGE2 in promoting fungal growth during infection. Thus, we describe the first mechanism of reliance on pathogen-derived eicosanoids in fungal pathogenesis and the specific role of 15-keto-PGE2 and host PPAR-γ in cryptococcosis

Evidence of Color Coherence Effects in W+jets Events from ppbar Collisions at sqrt(s) = 1.8 TeV

We report the results of a study of color coherence effects in ppbar collisions based on data collected by the D0 detector during the 1994-1995 run of the Fermilab Tevatron Collider, at a center of mass energy sqrt(s) = 1.8 TeV. Initial-to-final state color interference effects are studied by examining particle distribution patterns in events with a W boson and at least one jet. The data are compared to Monte Carlo simulations with different color coherence implementations and to an analytic modified-leading-logarithm perturbative calculation based on the local parton-hadron duality hypothesis.Comment: 13 pages, 6 figures.
