On the source of proper partitivity
Creators: name: Marty, Paul
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper investigates into the meaning and use of partitive constructions such as three of John’s lawyers. These constructions have long been observed to give rise to inferences of proper partitivity: upon hearing a sentence like Sue talked to three of John’s lawyers, we spontaneously understand that John has more than three lawyers, that is we interpret the partitive three of John’s lawyers as denoting a proper subset of the denotation of John’s lawyers. Contra the common idea that proper partitivity follows from the plain meaning of partitives, I defend here the view that partitives semantically express partitivity tout court, that is they encode the reflexive ‘part-of’ relation, and that proper partitivity comes about as a result of a presuppositional implicature on the basis of the competition between those indefinite expressions and their non-partitive definite alternatives, e.g., John’s three lawyers.

description: We study the information dynamics in a network of spin-$1/2$ particles when edges representing $XY$ interactions are randomly added to a disconnected graph accordingly to a probability distribution characterized by a "weighting" parameter. In this way we model dissipation of information initially localized in single or two qubits all over the network. We then show the dependence of this phenomenon from weighting parameter and size of the network.

description: While graph neural networks (GNNs) have been successful for node classification tasks and link prediction tasks in graph, learning graph-level representations still remains a challenge. For the graph-level representation, it is important to learn both representation of neighboring nodes, i.e., aggregation, and graph structural information. A number of graph pooling methods have been developed for this goal. However, most of the existing pooling methods utilize k-hop neighborhood without considering explicit structural information in a graph. In this paper, we propose Structure Prototype Guided Pooling (SPGP) that utilizes prior graph structures to overcome the limitation. SPGP formulates graph structures as learnable prototype vectors and computes the affinity between nodes and prototype vectors. This leads to a novel node scoring scheme that prioritizes informative nodes while encapsulating the useful structures of the graph. Our experimental results show that SPGP outperforms state-of-the-art graph pooling methods on graph classification benchmark datasets in both accuracy and scalability.

Towards a unified account of degree achievements and change of location verbs: the case of Spanish verbs with en-
Creators: name: Martínez Vera, Gabriel
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper discusses Spanish verbs that are prefixed with en-, e.g., en-suciar ‘to dirty’ and en-carcelar ‘to jail’ (the former is a degree achievement and the latter is a change of location verb). The aim of this paper is to make explicit what the parallels between both kinds of verbal predicates are and provide a semantics that captures these parallels. To this end, I propose that the prefix en- has a core meaning, which is based on the locative preposition en in Spanish (which roughly translates in English as ‘in/inside, on’) that can be used in the domain of degrees (in the case of degree achievements) and space (in the case of change of location verbs). My account makes an initial attempt to bridge two different domains focusing on verbal predicates of change. This proposal is, in principle, extensible to (at least) other Romance languages, which display a similar pattern.

description: Ruby grains are synthesized by laser heating of the dry mixture of Al$_2$O$_3$ and Cr$_2$O$_3$. Quasi-continuous radiation of a Nd:YAG laser was used for this purpose with average power of 15 W. Synthesized ruby grains demonstrate strong photo-luminescence in the vicinity of 700 nm. Synthesized ruby grains were integrated into a matrix made of flouro-polymer. Luminescene map acquired with the help of a photo-fluorimeter confirms efficient photo-conversion of green-blue radiation of the synthesize ruby into red region. Ruby grans can further be fragmented to smaller particles using the technique of laser fragmentation in liquids.
The CommitmentBank: Investigating projection in naturally occurring discourse
Creators: name: De Marneffe, Marie-Catherine
name: Simons, Mandy
name: Tonhauser, Judith
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper describes a new resource, the CommitmentBank, developed for the empirical investigation of the projection of finite clausal complements. A clausal complement is said to project when its content is understood as a commitment of the speaker even though the clause occurs under the scope of an entailment canceling operator such as negation or a question. The study of projection is therefore part of the study of commitments expressed by speakers to non-asserted sentence content. The content of clausal complements has been a central case for the study of projection, as there is a long-standing claim that clause-taking predicates fall into two classes—factives and nonfactives—distinguished on the basis of whether the contents of their complements project. This claim identifies the embedding predicate as the primary determinant of the projection behavior of these contents. The CommitmentBank is a corpus of naturally occurring discourses whose final sentence contains a clause-embedding predicate under an entailment canceling operator. In this paper, we describe the CommitmentBank and present initial results of analyses designed to evaluate the factive/nonfactive distinction and to investigate additional factors which affect the projectivity of clausal complements.

description: Currently there exists rather promising new trend in machine leaning (ML) based on the relationship between neural networks (NN) and Gaussian processes (GP), including many related subtopics, e.g., signal propagation in NNs, theoretical derivation of learning curve for NNs, QFT methods in ML, etc. An important feature of convolutional neural networks (CNN) is their equivariance (consistency) with respect to the symmetry transformations of the input data. In this work we establish a relationship between the many-channel limit for CNNs equivariant with respect to two-dimensional Euclidean group with vector-valued neuron activations and the corresponding independently introduced equivariant Gaussian processes (GP).

description: Two different experimental approaches were combined to study the electric dipole strength in the doubly-magic nucleus 48Ca below the neutron threshold. Real-photon scattering experiments using bremsstrahlung up to 9.9 MeV and nearly mono-energetic linearly polarized photons with energies between 6.6 and 9.51 MeV provided strength distribution and parities, and an (α,α'γ) experiment at E_α=136 MeV gave cross sections for an isoscalar probe. The unexpected difference observed in the dipole response is compared to calculations using the first-order random-phase approximation and points to an energy-dependent isospin character. A strong isoscalar state at 7.6 MeV was identified for the first time supporting a recent theoretical prediction.

description: We present nonlinear optical four-wave mixing in a silicon nanodisk dimer metasurface. Under the oblique incident plane waves, the designed metasurface exhibits a multi-resonant feature with simultaneous excitations of three quasi-bound states in the continuum (BIC). Through employing these quasi-BICs with maximizing electric field energy at the input bump wavelengths, significant enhancement of third-order nonlinear processes including third-harmonic generation, degenerate and non-degenerate four-wave mixing are demonstrated, giving rise to ten new frequencies in the visible wavelengths. This work may lead to a new frontier of ultracompact optical mixer for applications in optical circuitry, ultrasensitive sensing, and quantum nanophotonics.
Quality of Recovery in Elderly Cancer Patients

Publisher: name: Journal of the Portuguese Society of Anesthesiology
Year: 2018

description: Perioperative management of the elderly is an extensively debated issue. We aimed to determine the postoperative quality of recovery in very old patients submitted to neoplastic curative surgery.

An observational, prospective study was conducted including patients undergoing curative neoplastic surgery and admitted to the PACU. The Revised Cardiac Risk Index (RCRI) was applied. Very old patients (VOP) were considered for patients >80 years old. Vulnerability was evaluated using the Clinical Frailty Scale. Frailty was defined as a score≥4. The WHODAS 2.0 was used to assess preoperative disability, which was defined as a score≥25%. EuroQol5 dimensions (EQ-5D) was used to measure quality of life before surgery. The Postoperative Quality of Recovery Scale was used at baseline (up to 14 days before surgery) and after surgery at minute 15, 40 and days 1 and 3, evaluating recovery in several domains. Recovery was defined as return to baseline values in each domain (physiologic, nociceptive, emotional, functional and cognitive). The Mann-Whitney, Chi-square or Fisher’s exact test were used for comparison.

Of 148 patients, 12% were VOP, who had higher ASA physical status (p=0.002) and higher RCRI scores (p<0.001).VOP presented more problems at mobility (p=0.005), self-care (p=0.002) and usual activities (p=0.004), with the majority presenting frailty (p=0.032) and disability (p=0.007). Recovery was similar at all time points in every domain, except in the nociceptive domain at day 1 (p=0.042).

VOP had higher RCRI scores and presented more often with frailty, disability and limitations in EQ-5D. Nonetheless, in this study, they presented complete recovery with a frequency comparable to the other patients.

Throughput-Optimal Scheduling Design with Regular Service Guarantees in Wireless Networks

description: Motivated by the regular service requirements of video applications for improving Quality-of-Experience (QoE) of users, we consider the design of scheduling strategies in multi-hop wireless networks that not only maximize system throughput but also provide regular inter-service times for all links. Since the service regularity of links is related to the higher-order statistics of the arrival process and the policy operation, it is highly challenging to characterize and analyze directly. We overcome this obstacle by introducing a new quantity, namely the time-since-last-service (TSLS), which tracks the time since the last service. By combining it with the queue-length in the weight, we propose a novel maximum-weight type scheduling policy, called Regular Service Guarantee (RSG) Algorithm. The unique evolution of the TSLS counter poses significant challenges for the analysis of the RSG Algorithm. To tackle these challenges, we first propose a novel Lyapunov function to show the throughput optimality of the RSG Algorithm. Then, we prove that the RSG Algorithm can provide service regularity guarantees by using the Lyapunov-drift based analysis of the steady-state behavior of the stochastic processes. In particular, our algorithm can achieve a degree of service regularity within a factor of a fundamental lower bound we derive. This factor is a function of the system statistics and design parameters and can be as low as two in some special networks. Our results, both analytical and numerical, exhibit significant service regularity improvements over the traditional throughput-optimal policies, which reveals the importance of incorporating the metric of time-since-last-service into the scheduling policy for providing regulated service.

The pragmatics of semantic change: Modeling the progressive-to-imperfective shift
Creators: name: Lund, Gunnar
name: Jarvis, Rebecca
name: Scontras, Gregory
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: We implement a computational model of the cyclic progressive-to-imperfective shift, wherein languages with a single imperfective marker grammaticalize new progressive markers that ultimately broaden in interpretation and displace the older imperfective. While Deo (2015) offers a model of this process within the framework of evolutionary game theory, her model ultimately ignores the semantics she takes such care to construct. Our model, conceived within the Rational Speech Act modeling framework, offers a different perspective, operating directly over the utterance semantics. We show how semantic change may be a function of changes in utterance cost—a reflection of morphological complexity or frequency-of-use—as it relates to pragmatic reasoning. Counter to claims that grammaticalization is a process of conventionalization of implicature, our model holds the denotations of aspectual markers static; what changes is how we reason about their use given their changing costs.

description: This research determined the relationship between the dynamics of maize seed imports and the implementation of agricultural and trade policies on the dynamics of maize seed demand in Costa Rica. Maize imports depend on the real per capita income of national consumers, maize international price, and trade liberalization policies. The demand for seed depends on a fixed technical factor per hectare of maize harvested, so we modeled the maize harvested area function, which was found to follow an autoregressive component in response to yield and fertilizer price shocks. Policy makers can take these findings into account and incorporate them into the design of food security and trade relations policies.

description: In this paper we consider the influence of collisional fluctuations on the Mollow spectra of resonance fluorescence (RF). The fluctuations are taken into account by a simple shift of the constant detuning, involved in a set of optical Bloch equations by collision frequency noise which is modelled by a two-step random telegraph signal (RTS). We consider in detail the Mollow spectra for RF in the case of an arbitrary detuning of the laser frequency, where the emitter is a member of a statistical ensemble in thermodynamic equilibrium with the buffer gas at temperature $T$ which is treated as a colored environment, and velocity $v$ is distributed with the Maxwell-Boltzmann density.

description: The cold dark matter (CDM) structure formation scenario faces challenges on (sub)galactic scales, central among them being the `cusp-core' problem. A known remedy, driving CDM out of galactic centres, invokes interactions with baryons, through fluctuations in the gravitational potential arising from feedback or orbiting clumps of gas or stars. Here we interpret core formation in a hydrodynamic simulation in terms of a theoretical formulation, which may be considered a generalisation of Chandrasekhar's theory of two body relaxation to the case when the density fluctuations do not arise from white noise; it presents a simple characterisation of the effects of complex hydrodynamics and `subgrid physics'. The power spectrum of gaseous fluctuations is found to follow a power law over a range of scales, appropriate for a fully turbulent compressible medium. The potential fluctuations leading to core formation are nearly normally distributed, which allows for the energy transfer leading to core formation to be described as a standard diffusion process, initially increasing the velocity dispersion of test particles as in Chandrasekhar's theory. We calculate the energy transfer from the fluctuating gas to the halo and find it consistent with theoretical expectations. We also examine how the initial kinetic energy input to halo particles is redistributed to form a core. The temporal mass decrease inside the forming core may be fit by an exponential form; a simple prescription based on our model associates the characteristic timescale with an energy relaxation time. We compare the resulting theoretical density distribution with that in the simulation.

description: Evaluating the effects of moderation interventions is a task of paramount importance, as it allows assessing the success of content moderation processes. So far, intervention effects have been almost solely evaluated at the aggregated platform or community levels. Here, we carry out a multidimensional evaluation of the user-level effects of the sequence of moderation interventions that targeted r/The_Donald: a community of Donald Trump adherents on Reddit. We demonstrate that the interventions: 1) strongly reduced user activity; 2) slightly increased the diversity of the subreddits in which users participated; 3) slightly reduced user toxicity; and 4) gave way to the sharing of less factual and more politically biased news. Importantly, we also find that interventions having strong community level effects are associated to extreme and diversified user-level reactions. Our results highlight that community-level effects are not always representative of the underlying behavior of individuals or smaller user groups. We conclude by discussing the practical and ethical implications of our results. Overall, our findings can inform the development of targeted moderation interventions and provide useful guidance for policing online platforms.

A ‘situated’ solution to prior’s substitution problem
Creators: name: Liefke, Kristina
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: In the complements of many DP/CP-neutral attitude verbs (e.g. remember, fear, see), CPs resist the truth-preserving substitution by a DP of the form ‘the proposition [CP ]’. This substitution is often perceived as involving a shift in verb-reading from a reading in which the semantic value of the complement serves as the content of the attitude to a reading in which it serves as the object towards which the attitude is directed (see Moltmann’s 2003 objectivization effect). This paper provides a uniform account of the above phenomena that uses the particular pragmatic properties of the situation that serves as the internal argument of the attitude report. The resulting account is inspired by Pietroski (2000) and Forbes’ (2018) account of the objectivization effect and by Moltmann’s (2003) ‘unique determination’-strategy for the explanation of DP/CP substitution behavior. The account improves upon other accounts by explaining both the substitution behavior and the objectivization effect, and by explaining the validity (for some verbs) of the CP’s substitution by DPs like ‘the fact [CP ]’ or ‘the possibility [CP ]’.

description: We apply stochastic process theory to the analysis of immigrant integration. Using a unique and detailed data set from Spain, we study the relationship between local immigrant density and two social and two economic immigration quantifiers for the period 1999-2010. As opposed to the classic time-series approach, by letting immigrant density play the role of "time", and the quantifier the role of "space" it become possible to analyze the behavior of the quantifiers by means of continuous time random walks. Two classes of results are obtained. First we show that social integration quantifiers evolve following pure diffusion law, while the evolution of economic quantifiers exhibit ballistic dynamics. Second we make predictions of best and worst case scenarios taking into account large local fluctuations. Our stochastic process approach to integration lends itself to interesting forecasting scenarios which, in the hands of policy makers, have the potential to improve political responses to integration problems. For instance, estimating the standard first-passage time and maximum-span walk reveals local differences in integration performance for different immigration scenarios. Thus, by recognizing the importance of local fluctuations around national means, this research constitutes an important tool to assess the impact of immigration phenomena on municipal budgets and to set up solid multi-ethnic plans at the municipal level as immigration pressure build.

Contact processes with competitive dynamics in bipartite lattices: Effects of distinct interactions

description: The two-dimensional contact process (CP) with a competitive dynamics proposed by Martins {\it et al.} [Phys. Rev. E {\bf 84}, 011125(2011)] leads to the appearance of an unusual active asymmetric phase, in which the system sublattices are unequally populated. It differs from the usual CP only by the fact that particles also interact with their next-nearest neighbor sites via a distinct strength creation rate and for the inclusion of an inhibition effect, proportional to the local density. Aimed at investigating the robustness of such asymmetric phase, in this paper we study the influence of distinct interactions for two bidimensional CPs. In the first model, the interaction between first neighbors requires a minimal neighborhood of adjacent particles for creating new offspring, whereas second neighbors interact as usual (e.g. at least one neighboring particle is required). The second model takes the opposite situation, in which the restrictive dynamics is in the interaction between next-nearest neighbors sites. Both models are investigated under mean field theory (MFT) and Monte Carlo simulations. In similarity with results by Martins {\it et. al.}, the inclusion of distinct sublattice interactions maintain the occurrence of an asymmetric active phase and reentrant transition lines. In contrast, remarkable differences are presented, such as discontinuous phase transitions (even between the active phases), the appearance of tricritical points and the stabilization of active phases under larger values of control parameters. Finally, we have shown that the critical behaviors are not altered due to the change of interactions, in which the absorbing transitions belong to the directed percolation (DP) universality class, whereas second-order active phase transitions belong to the Ising universality class.

Stating the obvious: Of course as a focus-sensitive marker of uncontroversiality

description: The English discourse particle of course, part of a cross-linguistic class of elements that express the ‘uncontroversiality’ of a proposition, has received little attention from theoretical linguists. Studies in the domain of uncontroversiality, particularly of the German particles doch and ja, typically treat uncontroversiality as a property that holds of a proposition for all participants in a discourse. We first show that of course cannot be folded into prior treatments of doch and ja. Furthermore, we argue that of course motivates a finer-grained notion of uncontroversiality that is focus-sensitive and relativized to individual discourse participants. While our analysis in principle allows for relativizing uncontroversiality to multiple discourse participants, we argue that of course is semantically relativized only to the speaker. Rather than being lexically specified, we argue that the apparent addressee-oriented uncontroversiality conveyed by of course follows from general pragmatic reasoning about shared knowledge in a discourse.

Intonation and Expectation: English Mirative Contours and Particles
Creators: name: Kraus, Kelsey
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper proposes a novel account of the English discourse particles oh and huh. First, these particles are analyzed as being inherently mirative, betraying a speaker’s (violated) expectations in a discourse. Second, these particles are systematically paired with idiomatic prosodic contours and contexts to observe how their pragmatic interpretation shifts. Mirativity in English, it turns out, is not limited to particular particles, but can also be a property of prosodic contours. Sag and Lieberman (1975)’s Surprise-Redundancy Contour, is one of them. I propose that understanding the contribution of discourse particle requires intricate pragmatic reasoning strategies which enriches basic meaning of a discourse particle with the pragmatic discourse effects contributed by prosodic variation.

Calibration of neutron star natal kick velocities to isolated pulsar observations

description: Current prescriptions for supernova natal kicks in rapid binary population synthesis simulations are based on fits of simple functions to single pulsar velocity data. We explore a new parameterization of natal kicks received by neutron stars in isolated and binary systems developed by Mandel & Müller, which is based on 1D and 3D supernova simulations and accounts for the physical correlations between progenitor properties, remnant mass, and the kick velocity. We constrain two free parameters in this model using very long baseline interferometry velocity measurements of Galactic single pulsars. We find that the inferred values of natal kick parameters do not differ significantly between single and binary evolution scenarios. The best-fit values of these parameters are $v_{\rm ns} = 520$ km s$^{-1}$ for the scaling pre-factor for neutron star kicks, and $σ_{\rm ns}=0.3$ for the fractional stochastic scatter in the kick velocities.

Strong beliefs, weak commitments
Creators: name: Koev, Todor
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: The standard Hintikkan semantics views believe as a universal quantifier over possible worlds (Hintikka, 1969). This semantics (i) fails to capture the fact that believe is gradable (cf. partially believe or fully believe) and (ii) makes no predictions about the degree of certainty of the belief agent toward the prejacent. To remedy these problems, I propose a scalar semantics along the lines of Kennedy and McNally’s (2005) analysis of gradable adjectives, arguing that believe is a maximum-degree predicate. While belief attributions are sometimes interpreted as hedges (e.g., I believe it’s raining can be taken as a statement of uncertainty), I point out that such uses are restricted to contexts in which the belief component is not relevant to the question under discussion. Following up on a suggestion made in Chemla (2008), I propose that the weak sense of believe arises as an antipresupposition, a scalar inference derived through competition with a presuppositionally stronger know-competitor. Contra Hawthorne et al. (2016), I argue that the intuition of weakness is due not to reduced modal force but rather to the subjectivity of modal content, amounting to a situation in which the agent has full subjective confidence in the prejacent but fails to publicly commit to it.

Quantifiers in Comparatives
Creators: name: Krasikova, Sveta
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: In this paper I attempt to show that the availability of different interpretations in the comparatives with embedded quantifiers is not a matter of the relative scope of the involved operators. I contrast ‘should’-like modals, universal quantifiers over individuals, any-terms and non-epistemic possibility modals with a relatively small group of ‘have to’- like modals. I argue that the behaviour of the former does not support the flexibility of the scope approach – these expressions always result in the more-than-maximum reading. The latter class can indeed lead to different interpretations. To account for this pattern I propose a degree-based semantics for necessity modals like ‘have to’ and demonstrate that the observed readings under the comparative is a consequence of the interplay between the likelihood ordering introduced by the modal and the scale of the adjective. I further argue that the quasi universal interpretation of some existential quantifiers in the comparative context is due to the free choice implicature that strengthens the meaning of the embedded clause. I hope to show that the existing approaches to the analysis of comparatives do not have to resort to comparative-specific scope mechanisms.

On an Analogy between English Nominal and Polish Aspectual Manifestations of Genericity
Creators: name: Klimek-Jankowska, Dorota
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: The main goal of this study is to prove that two modal mechanisms Greenberg (2003) postulated for English indefinite singular (IS) and bare plural (BP) generics in the nominal domain are mirrored in Polish perfective and imperfective generics in the event domain. On the basis of Oosterhof’s (2006) argumentation, I justify the distinction between the GEN and the HAB intensional operators. With this distinction in mind, I associate the combination of HAB+perfective aspect as exemplifying the same kind of an ‘in virtue of’ modality as Greenberg postulates for the combination of GEN+IS. In the same manner, I claim that both the combination of GEN+BP and the combination of HAB+imperfective aspect exemplify either ‘descriptive’ or ‘in virtue of' modality.

description: Kusumoto (2005) argues against a scope analysis of tense in a Priorian system and for one where explicit tense variables appear in the object language of semantic analysis. She bases her argument partly on sentences where a verb in a relative clause is interpreted at a later time than the matrix verb, even though the relative clause occurs in a Determiner Phrase trapped below tense by an Negative Polarity Item. However, Kusumoto admits that her system alone does not explain the generalization noticed by Abusch (1988) that later-than-matrix readings for transitive intensional verbs correlate with de re readings of their objects. This paper argues for a version of the scope analysis of tense that accounts for both the Abusch and the Kusumoto facts, as well some new evidence that does not easily fit into an explicit tense variable system.

description: Esophageal neoplasm is the seventh cause of death from cancer in the world.1


Malignant tracheoesophageal or bronchoesophageal or, less commonly, esophageal-lung parenchyma fistulas are late developments of advanced cancer of the esophagus, lung or mediastinum.2 The occurrence of an esophago-respiratory malignant fistula is a devastating complication.1 The presence of a respiratory prothesis increases the risk. Its displacement can lead to several complications including total airwaiy obstruction.


There are multiple anaesthetic problems presented by patients with respiratory fistulas.3


We describe the anaesthetic management of a 56 year old male patient with a metastatic esophageal cancer diagnosed with a malignant broncho-esophageal fistula and a tracheal prothesis proposed to emergent laparotomy.


The anaesthetic management of a patient with an esophago-respiratory malignant fistula is a serious challenge. Our patient had a tracheal prothesis that also raised life-threatening problems during his anaesthetic management. Multipe cares in the perioeprative period were mandatory.

Contrast and Underspecification. The Semantics of 'aber' and 'doch'
Creators: name: Karagjosova, Elena
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: I present an unitary analysis of the German adversative connectors aber and doch, based on Sæbø (2003), where the semantics of these connectors is defined in terms of a presupposition involving negation and topic alternatives. I argue that the meaning of aber and doch is underspecified between various types of contrast and that the type of contrast they indicate in particular context is determined by the configuration of topic alternatives at hand, which in turn is correlated with the particular syntactic and prosodic properties of the connectors in the concrete discourse as well as with the type of discourse (coordination, dialogue) in which the connectors are used. Finally, I sketch an underspecified semantic representation of the meaning of aber and doch and hint at a disambiguation algorithm that allows the bottom up construction of discourses with these connectors starting from their underspecified representation and employing information about their syntactic and prosodic properties as well as about the information structure and the discourse structure of the particular context in which they occur.
