Do Inter-sectoral Linkages Matter for International Export Specialisation?

This paper basically adopts a ‘technology gap’ approach for explaining international export specialisation. Within this broad label there has been one tradition which has applied cumulativeness in technological change as an explanation, while another tradition has emphasised the role of inter-sectoral linkages (the so-called home market effect) in this context. However, given that the sources of innovation (inducements mechanisms) differ between firms according to principal sector of activity, different variables should not be expected to be of equal importance across industrial sectors. Thus, using the Pavitt taxonomy as a starting point, the paper statistically investigates the importance of variables reflecting different inducement mechanisms, across 9 OECD countries. The paper concludes that the two types of technological activities, namely technological activities in the ‘own’ sector, and inter-sectoral linkages are both important in the determination of national export specialisation patterns. However, the importance differ according to the mode of innovation in each type of sector.international export specialisation, patent data, input-output analysis, inter-sectoral li

Quantum curves and topological recursion

This is a survey article describing the relationship between quantum curves and topological recursion. A quantum curve is a Schr\"odinger operator-like noncommutative analogue of a plane curve which encodes (quantum) enumerative invariants in a new and interesting way. The Schr\"odinger operator annihilates a wave function which can be constructed using the WKB method, and conjecturally constructed in a rather different way via topological recursion.Comment: This article arose out of the Banff workshop Quantum Curves and Quantum Knot Invariants.

Analysis Framework for Translation of Maritime Legal Documents

Maritime activity around the globe currently generates a great amount of translation work, especially from English into other languages. This paper focuses on the analysis of the translation process in maritime legal and administrative documents. The study first establishes which maritime documents are most often translated and a tool is then developed to analyse such documents in detail, based on the concept of textual genre. Such analysis would help translators to better understand these highly specialised documents and thus contribute towards improving translation of the same

PP-adic LL-functions of Bianchi modular forms

The theory of overconvergent modular symbols, developed by Rob Pollack and Glenn Stevens, gives a beautiful and effective construction of the $p$-adic $L$-function of a modular form. In this paper, we give an analogue of their results for Bianchi modular forms, that is, modular forms over imaginary quadratic fields. In particular, we prove control theorems that say that the canonical specialisation map from overconvergent to classical Bianchi modular symbols is an isomorphism on small slope eigenspaces of suitable Hecke operators. We also give an explicit link between the classical modular symbol attached to a Bianchi modular form and critical values of its $L$-function, which then allows us to construct $p$-adic $L$-functions of Bianchi modular forms.Comment: 41 pages. I have relaxed a condition, previously assumed throughout, that the primes above p are principal. I have also made various minor improvements and corrections throughou

The Weierstrass subgroup of a curve has maximal rank

We show that the Weierstrass points of the generic curve of genus $g$ over an algebraically closed field of characteristic 0 generate a group of maximal rank in the Jacobian
