What\u27s in a Span? Evaluating the Creativity of a Span-Based Neural Constituency Parser

Constituency parsing is generally evaluated superficially, particularly in a multiple language setting, with only F-scores being re-ported. As new state-of-the-art chart-based parsers have resulted in a transition from traditional PCFG-based grammars to span-based approaches (Stern et al., 2017; Gaddy et al.,2018), we do not have a good understanding of how such fundamentally different approaches interact with various treebanks as results show improvements across treebanks (Kitaev and Klein, 2018), but it is unclear what influence annotation schemes have on various treebank performance (Kitaev et al., 2019). In particular, a span-based parser’s capability of creating novel rules is an unknown factor. We perform an analysis of how span-based parsing performs across 11 treebanks in order to examine the overall behavior of this parsing approach and the effect of the treebanks’ specific annotations on results. We find that the parser tends to prefer flatter trees, but the approach works well because it is robust enough to adapt to differences in annotation schemes across treebanks and languages

How funding structures for HIV/AIDS research shape outputs and utilization: a Swiss case study

Background: Research policy in the field of HIV has changed substantially in recent decades in Switzerland. Until 2004, social science research on HIV/AIDS was funded by specialized funding agencies. After 2004, funding of such research was “normalized” and integrated into the Swiss National Science Foundation as the main funding agency for scientific research in Switzerland. This paper offers a longitudinal analysis of the relationship between the changing nature of funding structures on the one hand and the production and communication of policy-relevant scientific knowledge in the field of HIV on the other hand. Methods: The analysis relies on an inventory of all social sciences research projects on HIV in Switzerland that were funded between 1987 and 2010, including topics covered and disciplines involved, as well as financial data. In addition, in-depth interviews were conducted with 18 stakeholders. Results: The analysis highlights that the pre-2004 funding policy ensured good coverage of important social science research themes. Specific incentives and explicit promotion of social science research related to HIV gave rise to a multidisciplinary, integrative and health-oriented approach. The abolition of a specific funding policy in 2004 was paralleled by a drastic reduction in the number of social science research projects submitted for funding, and a decline of public money dedicated to such research. Although the public administration in charge of HIV policy still acknowledges the relevance of findings from social sciences for the development of prevention, treatment and care, HIV-related social science research does not flourish under current funding conditions. Conclusions: The Swiss experience sheds light on the difficulties of sustaining social science research and multidisciplinary approaches related to HIV without specialized funding agencies. Future funding policy might not necessarily require specialized agencies, but should better take into account research dynamics and motivations in the field of social sciences

Towards a Representative Bureaucracy: Promoting Linguistic Representation and Diversity in the Swiss and Canadian Federal Public Services

Drawing on the concept of representative bureaucracy, this article examines how two multilingual states - Canada and Switzerland - deal with issues related to the participation of different linguistic communities in the federal public service. Following a political mobilization of the linguistic cleavage, strategies to promote multilingualism in the public service have been adopted in both countries. The Canadian strategy focuses on equal treatment of Anglophones and Francophones in the public service. In Switzerland, adequate representation of the linguistic communities is the primary goal. These differences are explained by the characteristics of the linguistic regimes in each of the two countries as well as by the peculiarities of consociational democracy in Switzerland. In both countries, the linguistic origins of public administration staff, overall, mirrors the proportions of the linguistic communities in the wider society. Within administrative units, however, linguistic diversity is hampered by the logics of language rationalization, where minorities are under pressure to communicate in the language of the majorit

The Cost-Effectiveness of HIV/STI Prevention in High-Income Countries with Concentrated Epidemic Settings: A Scoping Review

The purpose of this scoping review is to establish the state of the art on economic evaluations in the field of HIV/STI prevention in high-income countries with concentrated epidemic settings and to assess what we know about the cost-effectiveness of different measures. We reviewed economic evaluations of HIV/STI prevention measures published in the Web of Science and Cost-Effectiveness Registry databases. We included a total of 157 studies focusing on structural, behavioural, and biomedical interventions, covering a variety of contexts, target populations and approaches. The majority of studies are based on mathematical modelling and demonstrate that the preventive measures under scrutiny are cost-effective. Interventions targeted at high-risk populations yield the most favourable results. The generalisability and transferability of the study results are limited due to the heterogeneity of the populations, settings and methods involved. Furthermore, the results depend heavily on modelling assumptions. Since evidence is unequally distributed, we discuss implications for future research

Vers une bureaucratie représentative. La promotion de la représentation et de la diversité linguistiques dans l'administration fédérale en Suisse et au Canada

Résumé. Sous l'angle du concept de bureaucratie représentative, le présent article compare la gestion des enjeux liés à la participation des différentes communautés linguistiques dans l'administration publique de deux États multilingues : le Canada et la Suisse. À la suite de la mobilisation politique autour du clivage linguistique, des stratégies de promotion du plurilinguisme ont été adoptées dans les deux pays. La stratégie canadienne mise sur l'égalité de traitement des fonctionnaires anglophones et francophones. La Suisse poursuit quant à elle l'objectif de la représentation des différentes communautés linguistiques dans la fonction publique. Ces différences de fond s'expliquent, entre autres, par la nature du régime linguistique en place et par le contexte de démocratie consociationnelle en Suisse. La participation proportionnelle des communautés linguistiques au sein de l'administration fédérale est globalement atteinte dans les deux pays. Cependant, au niveau du fonctionnement interne, une logique de rationalité linguistique exerce une pression sur les groupes minoritaires pour qu'ils adoptent la langue majoritaire. Abstract.
