A modal ambiguity in for-infinitival relative clauses
This squib presents two puzzles related to an ambiguity found in for-infinitival relative clauses (FIRs). FIRs invariably receive a modal interpretation even in the absence of any overt modal verb. The modal interpretation seems to come in two distinct types, which can be paraphrased by finite relative clauses employing the modal auxiliaries should and could. The two puzzles presented here arise because the availability of the two readings is constrained by factors that are not otherwise known to affect the interpretation of a relative clause. Specifically, we show, first, that âstrongâ determiners require the FIR to be interpreted as a SHOULD-relative while âweakâ determiners allow both interpretations (the Determiner-Modal Generalization). Secondly, we observe that the COULD-interpretation requires a raising (internally headed) structure for the FIR, while the SHOULD-interpretation is compatible with either a raising or a more standard matching (externally headed) structure (the Raising/Matching Generalization)
Secondary predication and the distribution of raising to object
In Den Dikken (2017b) arguments are presented for a predicational approach to hyperraising and copy raising constructions in which the âraisedâ DP serves as the subject of the matrix clause. In this sequel, I show that hyperraising and copy raising also occur in secondary predication constructions embedded under propositional attitude verbs such as consider. An examination of the properties of these hyperraising and copy raising to object constructions leads to the conclusion that overt subject-toobject raising (âobject shiftâ) definitely exists in English but is obligatory only for subjects of small-clause complements of verbs. Apart from yielding a clearer perspective on the distribution of overt object shift in English, the study also delivers a unified account of a variety of restrictions on the subject of the non-finite complement of propositional attitude verbs
Towards incorporation of blue carbon in Falkland Islands marine spatial planning: a multi-tiered approach
Ecosystem-based conservation that includes carbon sinks, alongside a linked carbon credit system, as part of a nature-based solution to combating climate change, could help reduce greenhouse gas levels and therefore the impact of their emissions. Blue carbon habitats and pathways can also facilitate biodiversity retention, aiding sustainable fisheries and island economies. However, robust blue carbon research is often limited at the scale of regional governance and management, lacking both incentives and facilitation of policy-integration. The remote and highly biodiverse coastal ecosystems and surrounding continental shelf can be used to better inform long-term ecosystem-based management in the vast South Atlantic Ocean and sub-Antarctic, to synergistically protect both unique biodiversity and inform on the magnitude of nature-based benefits they provide. Understanding key ecosystem information such as their location, extent, and condition of habitat types, will be critical in understanding carbon pathways to sequestration, threats to this, and vulnerability. This paper considers the current status of blue carbon data and information available, and what is still required before blue carbon can be used as a conservation management tool integrated in national Marine Spatial Planning (MSP) initiatives. Our research indicates that the data and information gathered has enabled baselines for a number of different blue carbon ecosystems, and indicated potential threats and vulnerability that need to be managed. However, significant knowledge gaps remain across habitats, such as salt marsh, mudflats and the mesophotic zones, which hinders meaningful progress on the ground where it is needed most
Quantifier scope in sentence prosody? : A view from production
Logical scope interpretation and sentence prosody exhibit intricate, yet scarcely studied interrelations across a variety of languages and constructions. Despite these observable interrelations, it is not clear whether quantifier scope by itself is able to directly affect prosodic form. Information structure is a key potential confounding factor, as it appears to richly interact both with scope interpretation and with prosodic form.
To address this complication, the current study investigates, based on data from Hungarian, whether quantifier scope is expressed prosodically if information structure is kept in check. A production experiment is presented that investigates grammatically scope ambiguous doubly quantified sentences with varied focus structures, while lacking a syntactically marked topic or focus. In contrast to the information structural manipulation, which is manifest in the analysis of the acoustic data, the results reveal no prosodic effect of quantifier scope, nor the interaction of scope with information structure. This finding casts doubt on the notion that logical scope can receive direct prosodic expression, and it indirectly corroborates the restrictive view instead that scope interpretation is encoded in prosody only in cases in which it is a free rider on information structure
Of false promises and good bets: a plea for a pragmatic approach to theory building (the Tartu lecture)
The POEMMA (Probe of Extreme Multi-Messenger Astrophysics) mission
The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) is designed to
observe cosmic neutrinos (CNs) above 20 PeV and ultra-high energy cosmic rays
(UHECRs) above 20 EeV over the full sky. The POEMMA mission calls for two
identical satellites flying in loose formation, each comprised of a 4-meter
wide field-of-view (45 degrees) Schmidt photometer. The hybrid focal surface
includes a fast (1 s) ultraviolet camera for fluorescence observations
and an ultrafast (10 ns) optical camera for Cherenkov observations. POEMMA will
provide new multi-messenger windows onto the most energetic events in the
universe, enabling the study of new astrophysics and particle physics at these
otherwise inaccessible energies.Comment: 8 pages, 6 figures, presented in 36th International Cosmic Ray

The Roadmap to the POEMMA mission
The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) is designed to observe ultrahigh-energy cosmic rays (UHECRs) and cosmic neutrinos from space with sensitivity over the full celestial sky. Developed as a NASA Astrophysics Probe-class mission, POEMMA consists of two identical telescopes orbiting the Earth in a loose formation designed to observe extensive air showers (EAS) via air fluorescence and Cherenkov emissions. UHECRs and UHE neutrinos above 20 EeV are observed with the stereo fluorescence technique, while tau neutrinos above 20 PeV are observed via the optical Cherenkov signals produced by up-going EAS generated by the decay of Earth-emerging tau-leptons. The POEMMA satellites are designed to quickly re-orientate to follow up transient cosmic neutrino candidate sources and obtain unparalleled neutrino flux sensitivity. Both observation techniques and the instrument design are being validated by current and upcoming missions, such as Mini-EUSO and EUSO-SPB as part of the JEM-EUSO program, and the Terzina instrument onboard the NUSES SmallSat mission. We discuss the POEMMA science performance and the current roadmap to the POEMMA mission
