    With less than 4,500 of its population of around 600,000 living overseas in 2013, the Solomon Islands ranks 138th in the world for diaspora formation. At these levels the scale of the diaspora as a proportion of population (0.8 percent) remains lower than it was in the early 20th century, when more than 5,000 Solomon islanders were compulsorily repatriated from Queensland under early Australian Commonwealth legislation. This working paper retraces and reframes the history of Solomon Islands labour mobility and diaspora formation since the 1850s, considering it in relation to the wider institutional and macro-regulatory machineries of three phases or regimes of economic, trade and mobility regulation. These regimes are referred to in this paper as: 1.liberal imperial, 2. national territorial and 3. International neoliberal. We argue that Solomon Islanders’ participation in labour mobility has been substantial under all three phases, but that international mobility and diaspora formation only developed significantly under the liberal imperial regime. Even then, however, its development proved precarious. The ways regional actors and governments acting within the different regimes have framed and segmented labour markets continue to powerfully shape mobility and diaspora outcomes. The paper concludes with a discussion of the implications of the situation to date for future economic development and security in Solomon Islands

    Variations on the Theme of Remembering: A National Survey of How Canadians Use the Past

    This paper in collective remembering is based on a telephone survey of 3,419 adult residents of Canada. The questionnaire contains over 70 questions. The interviews average over 20 minutes in length. Part of the Canadians and Their Pasts project, the survey seeks to assess how Canadians use the past in daily life. How many engage in activities related to the past, such as reading books, viewing photos, or visiting museums and historic sites? How do they evaluate different sources of information about the past? What types of past — family, province, nation, ethnic group — are most important to them? The paper suggests that the construction and reconstruction of autobiographical memory is a fundamental aspect of one’s uses of the past. It also proposes that wider collective pasts are particularly important among members of minority and alternative groups. And that the past of the nation-state figures more prominently in these citizens’ reflections than Roy Rosenzweig and David Thelen observed in their similar study, The Presence of the Past: Popular Uses of History in American Life (1998).Cette Ă©tude de remĂ©moration collective s’appuie sur une enquĂȘte tĂ©lĂ©phonique menĂ©e auprĂšs de 3,419 adultes rĂ©sidant au Canada. Comportant plus de 70 questions et nĂ©cessitant des entretiens de plus de 20 minutes, l’enquĂȘte, effectuĂ©e dans le cadre du projet Les Canadiens et leurs passĂ©s, vise Ă  Ă©valuer l’utilisation du passĂ© dans la vie de tous les jours. Combien de Canadiens et de Canadiennes se livrent Ă  des activitĂ©s liĂ©es au passĂ©, telles que lire un livre, regarder des photos ou visiter un musĂ©e ou un lieu historique? Comment Ă©valuent-ils les diffĂ©rentes sources d’information sur le passĂ©? Quels types de passĂ© priment pour eux : celui de leur famille, de leur province, de leur pays, de leur groupe ethnique? Le prĂ©sent article avance l’idĂ©e que la construction et la reconstruction du souvenir autobiographique sont des aspects fondamentaux de l’utilisation du passĂ©. Il affirme que les passĂ©s collectifs sont tout particuliĂšrement importants chez les membres des minoritĂ©s et des groupes divergents. Et il laisse entendre que le passĂ© de l’État-nation est beaucoup plus prĂ©sent dans les rĂ©flexions de ces citoyens que ne l’ont constatĂ© Roy Rosenzweig et David Thelen dans leur Ă©tude semblable, The Presence of the Past: Popular Uses of History in American Life (1998)

    Cancellation of the sigma mode in the thermal pion gas by quark Pauli blocking

    Full text link
    We calculate the pressure of the interacting pion gas using the Beth-Uhlenbeck approach to the relativistic virial expansion with Breit-Wigner phase shifts for the σ\sigma- and ϱ\varrho- meson resonances. The repulsive phase shift ÎŽ02\delta^2_0 is taken from quark interchange model of Barnes and Swanson [Phys. Rev. D 46 (1992) 131] in very good agreement with experimental data. In this work we show that the cancellation of the attractive (I = 0) and repulsive (I = 2) isospin channel contributions to the scalar π−π\pi-\pi interaction in the low-energy region that is known for the vacuum phase shifts, takes place also at finite temperature. This happens despite the strong medium dependence of these phase shifts that enters our model by the temperature dependence of the σ\sigma- meson and constituent quark masses because for these masses the relation mσ(T)≈2mq(T)m_\sigma(T) \approx 2 m_q (T) holds and the scattering length approximation is valid as long as the strong decay channel σ→ππ\sigma \to \pi \pi is open. Exploiting the Nambu--Jona-Lasinio model for describing the dynamical breaking of chiral symmetry in the vacuum and its restoration at finite temperature, we justify with our approach that the σ\sigma-meson should be absent from the hadron resonance gas description at low temperatures because the above cancellation holds. However, since this cancellation breaks down in the vicinity of the hadronization transition, where due to chiral symmetry restoration the decay channel σ→ππ\sigma \to \pi \pi closes and the σ\sigma- meson becomes a good resonance, the latter should be included into the statistical model description of chemical freeze-out in heavy-ion collisions.Comment: 8 pages, 4 figures, revision of text, references and figure

    Supernova Resonance--scattering Line Profiles in the Absence of a Photosphere

    Get PDF
    In supernova spectroscopy relatively little attention has been given to the properties of optically thick spectral lines in epochs following the photosphere's recession. Most treatments and analyses of post-photospheric optical spectra of supernovae assume that forbidden-line emission comprises most if not all spectral features. However, evidence exists which suggests that some spectra exhibit line profiles formed via optically thick resonance-scattering even months or years after the supernova explosion. To explore this possibility we present a geometrical approach to supernova spectrum formation based on the "Elementary Supernova" model, wherein we investigate the characteristics of resonance-scattering in optically thick lines while replacing the photosphere with a transparent central core emitting non-blackbody continuum radiation, akin to the optical continuum provided by decaying 56Co formed during the explosion. We develop the mathematical framework necessary for solving the radiative transfer equation under these conditions, and calculate spectra for both isolated and blended lines. Our comparisons with analogous results from the Elementary Supernova code SYNOW reveal several marked differences in line formation. Most notably, resonance lines in these conditions form P Cygni-like profiles, but the emission peaks and absorption troughs shift redward and blueward, respectively, from the line's rest wavelength by a significant amount, despite the spherically symmetric distribution of the line optical depth in the ejecta. These properties and others that we find in this work could lead to misidentification of lines or misattribution of properties of line-forming material at post-photospheric times in supernova optical spectra.Comment: 37 pages, 24 figures; accepted for publication in ApJ Supplement Serie

    The book edition of the Universe Special Issue “Compact Stars in the QCD Phase Diagram” is devoted to the overarching aspects shared between heavy-ion collisions and compact star astrophysics in investigating the hadron-to-quark matter phase transition in the equation of state of strongly interacting matter in different regions of the phase diagram of QCD. It comprises 22 review and research articles that, together, will serve as a useful guide in educating both young and senior scientists in this emerging field that represents an intersection of the communities of strongly interacting matter theory, heavy-ion collision physics and compact star astrophysics

    Examining the Efficacy of Inquiry-based Approaches to Education

    Get PDF
    Educational jurisdictions around the world have introduced curricular initiatives that emphasize the need for students to engage in inquiry-based education. This shift, has been met by significant public opposition, particularly in the Canadian context. Results from this study indicate that criticisms of inquiry-based approaches to education are largely directed at discovery learning, which has limited educational value. We note the significant affordances of guided forms of inquiry, such as problem-based learning, and approaches to inquiry aligned with the authentic education movement. Additionally, we highlight the specific instructional supports needed for processes of inquiry to promote elements, such as critical thinking skills and flexible problem solving abilities, necessary for success in a rapidly changing world

    Social Capital, Institutional Rules, and Constitutional Amendment Rates

    Get PDF
    Why are some constitutions amended more frequently than others? The literature provides few clear answers, as some scholars focus on institutional factors, whereas others emphasize amendment culture. We bridge this divide with new theoretical and empirical insights. Using data from democratic constitutions worldwide and U.S. state constitutions, we examine how social capital reduces the transaction costs imposed by amendment rules. The results indicate that constitutional rigidity decreases amendment frequency, but group membership, civic activism, and political trust can offset the effect of amendment rules. Our findings have important implications for scholars in public law, constitutional and democratic theory, and social movements
