description: The current fluctuations due to a temperature bias, i.e. the delta-$T$ noise, allow one to access properties of strongly interacting systems which cannot be addressed by the usual voltage-induced noise. In this work, we study the full delta-$T$ noise between two different fractional quantum Hall edge states, with filling factors $(ν_L,ν_R)$ in the Laughlin sequence, coupled through a quantum point contact and connected to two reservoirs at different temperatures. We are able to solve exactly the problem for all couplings and for any set of temperatures in the specific case of an hybrid junction $(1/3,1)$. Moreover, we derive a universal analytical expression which connects the delta-$T$ noise to the equilibrium one valid for all generic pairs $(ν_L,ν_R)$ up to the first order in the temperature mismatch. We expect that the linear term can be accessible in nowadays experimental set-ups. We describe the two opposite coupling regimes focusing on the strong one which correspond to a non-trivial situation. Our analysis on delta-$T$ noise allows us to better understand the transport properties of strongly interacting systems and to move toward more involved investigation concerning the statistics and scaling dimension of their emergent excitations.

Reflexivity and Reciprocity with(out) Underspecification
Creators: name: Murray, Sarah E.
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: In languages like English, reflexivity and reciprocity are expressed by distinct proforms. However, many languages, such as Cheyenne, express reflexivity and reciprocity with a single proform. In this paper I utilize Dynamic Plural Logic (van den Berg, 1996) to a draw a semantic parallel between reflexive and reciprocal anaphors in English. I propose that they contribute overlapping but distinct requirements on the relations introduced by transitive verbs, requirements which fully specify reflexivity and reciprocity. This parallel is then extended to Cheyenne by appealing to underspecification. I propose the Cheyenne affix which expresses both reflexivity and reciprocity contributes only the shared requirement of the English anaphors. It is thus underspecified, not ambiguous. This accounts for its compatibility with both singular and plural antecedents as well as its variety of construals.

description: Quantum tori are limits of finite dimensional C*-algebras for the quantum Gromov-Hausdorff propinquity, a metric defined by the author as a strengthening of Rieffel's quantum Gromov-Hausdorff designed to retain the C*-algebraic structure. In this paper, we propose a proof of the continuity of the family of quantum and fuzzy tori which relies on explicit representations of the C*-algebras rather than on more abstract arguments, in a manner which takes full advantage of the notion of bridge defining the quantum propinquity.

Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper focuses on the expression of number in Karitiana. It claims that both its noun and its verb have cumulative denotations, and argues that pluractional affixes perform a plural operation on verb denotations that subtracts its singular events. The paper provides evidence for a difference between lexical and phrasal cumulativity as proposed in Kratzer 2001, 2005.

Domain walls in two-dimensional nematics confined in a small circular cavity

Year: 2014

description: Using Monte Carlo simulation, we study a fluid of two-dimensional hard rods inside a small circular cavity bounded by a hard wall, from the dilute regime to the high-density, layering regime. Both planar and homeotropic anchoring of the nematic director can be induced at the walls through a free-energy penalty. The circular geometry creates frustration in the nematic phase and a polar-symmetry configuration with a distorted director field plus two $+1/2$ disclinations is created. At higher densities, a quasi-uniform structure is observed with a (minimal) director distortion which is relaxed via the formation of orientational domain walls. This novel structure is not predicted by elasticity theory and is similar to the step-like structures observed in three-dimensional hybrid slit pores. We speculate that the formation of domain walls is a general mechanism to relax elastic stresses in conditions of strong surface anchoring and severe spatial confinement.

Particles, Modality and Coherence
Creators: name: McCready, Eric
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper considers some aspects of the meaning of sentence-final particles. Such particles have a use on which they serve to emphasize what is said, and a use on which they have a modal semantics. The present paper is an attempt to unify these two uses from the perspective of discourse coherence. The conclusion is that sentence-final particles are used to maintain coherence.

Analyticity under Perspective: Indefinite Generics in French
Creators: name: Mari, Alda
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: Starting from the observation that a sentence like ??a dog is intelligent is difficult in the generic domain in the same way as ??a student is shy is in the existential one, this paper argues that as for the existential reading, the generic interpretation of the indefinites also needs a “context”. Adopting an explicit modal interpretation of GEN, our account builds on Greenberg (2002) insight that indefinite generic sentences require a special kind of modal bases. After pointing out some shortcomings of Greenberg’s theory, we propose an account of point of views as restrictors of modal bases. We represent point of views as world-judge pairs à la Ross (1997) and show that, besides modals, which always rescue indefinite generic sentences different phenomena like contrast, focus, evaluative adverbs and evidential uses of propositional attitude verbs are also manifestations of point of views.

The Sortal Theory of Plurals
Creators: name: Magri, Giorgio
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper explores the hypothesis of a semantics for plurals with no atomic partial order defined on the domain of quantification, and thus no ontological distinction between singular and plural individuals. The idea is that the work usually done in the semantics by the atomic partial order is instead done by the syntax, which makes available to the semantics a phonologically covert sortal which provides the suitable granularity. This sortal theory of plurals is compared to the standard atomic theory with the two case studies of partitives and distributivity.

description: How much spectral information is needed to determine the correlation functions of a conformal theory? We study this question in the context of planar supersymmetric Yang-Mills theory, where integrability techniques accurately determine the single-trace spectrum at finite 't Hooft coupling. Corresponding OPE coefficients are constrained by dispersive sum rules, which implement crossing symmetry. Focusing on correlators of four stress-tensor multiplets, we construct combinations of sum rules which determine one-loop correlators, and we study a numerical bootstrap problem that nonperturbatively bounds planar OPE coefficients. We observe interesting cusps at the location of physical operators, and we obtain a nontrivial upper bound on the OPE coefficient of the Konishi operator outside the perturbative regime.

Contrast For Two

Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: Bridge accents in German are known for their pragmatic effects. In this paper, these effects are accounted for by a new analysis claiming that bridge accent sentences implicate the possibility of a true statement where both accented elements are replaced by alternatives. This account is compared to the one by Büring (1997) and shown to handle some data in a more accurate way. Finally, an attempt is made to relate the phenomenon intonationally to other phenomena, in particular series and pair-lists, and to show how it could be derived from more basic principles of intonation.

description: We investigate the theoretically achievable fidelities when coherently controlling an effective three qubit system consisting of a negatively charged nitrogen vacancy (NV$^-$) center in diamond with an additional nearby carbon $^{13}$C spin $I_{\text{C}}=1/2$ via square radio and microwave frequency pulses in different magnetic field regimes. Such a system has potentially interesting applications in quantum information related tasks such as distributed quantum computation or quantum repeater schemes. We find that the best fidelities can be achieved in an intermediate magnetic field regime. However, with only square pulses it will be challenging to reach the fidelity threshold(s) predicted by current models of fault-tolerant quantum computing.

description: We study how the number of employed modes impacts the ability to witness non-Markovian evolutions via correlation backflows in continuous-variable quantum dynamics. We first prove the existence of non-Markovian Gaussian evolutions that do not show any revivals in the correlations between the mode evolving through the dynamics and a single ancillary mode. We then demonstrate how this scenario radically changes when two ancillary modes are considered. Indeed, we show that the same evolutions can show correlation backflows along a specific bipartition when three-mode states are employed, and where only one mode is subjected to the evolution. These results can be interpreted as a form of activation phenomenon in non-Markovianity detection and are proven for two types of correlations, entanglement and steering, and two classes of Gaussian evolutions, a classical noise model and the quantum Brownian motion model.

description: The magnetic vortex structure, an important ground state configuration in micron and sub-micron sized ferromagnetic thin film platelets, is characterized by a curling in-plane magnetization and, in the center, a minuscule region with out-of-plane magnetization, the vortex core, which points either up or down. It has already been demonstrated that the vortex core polarity can be reversed with external AC magnetic fields, frequency-tuned to the (sub-GHz) gyrotropic eigenmode or to (multi-GHz) azimuthal spin wave modes, where reversal times in the sub-ns regime can be realized. This fast vortex core switching may also be of technological interest as the vortex core polarity can be regarded as one data bit. Here we experimentally demonstrate that unidirectional vortex core reversal by excitation with sub-100 ps long orthogonal monopolar magnetic pulse sequences is possible in a wide range of pulse lengths and amplitudes. The application of such short digital pulses is the favourable excitation scheme for technological applications. Measured phase diagrams of this unidirectional, spin wave mediated vortex core reversal are in good qualitative agreement with phase diagrams obtained from micromagnetic simulations. The time dependence of the reversal process, observed by time-resolved scanning transmission X-ray microscopy indicates a switching time of 100 ps and fits well with our simulations. The origin of the asymmetric response to clockwise and counter clockwise excitation which is a prerequisite for reliable unidirectional switching is discussed, based on the gyromode - spin wave coupling.

description: We study the diffusion of particles confined close to a single wall and in double-wall planar channel geometries where the local diffusivities depend on the distance to the boundaries. Displacement parallel to the walls is Brownian as characterized by its variance, but it is non-Gaussian having a non-zero fourth cumulant. Establishing a link with Taylor dispersion, we calculate the fourth cumulant and the tails of the displacement distribution for general diffusivity tensors along with potentials generated by either the walls or externally, for instance gravity. Experimental and numerical studies of the motion of a colloid in the direction parallel to the wall give measured fourth cumulants which are correctly predicted by our theory. Interestingly, contrary to models of Brownian-yet-non-Gaussian diffusion, the tails of the displacement distribution are shown to be Gaussian rather than exponential. All together, our results provide additional tests and constraints for the inference of force maps and local transport properties near surfaces.
The Temporal Interpretation of the Korean '–ko' Construction: Aktionsart and Discourse Context
Creators: name: Lee, Jungmee
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: The temporal interpretation of the Korean –ko construction has been given analyses that assume a construction-specific mechanism (e.g. Yoon 1993, 1994, 1997; Chung 2001, 2005). This paper presents several empirical arguments against these analyses, and develops a compositional analysis. The main point of this paper is that the temporal interpretation of the –ko construction can be accounted for in terms of an independently motivated principle regarding the effect of Aktionsart and discourse context on temporal interpretations. Given that Aktionsart and discourse context also govern the temporal interpretation of Korean simple sentences in discourse, I conclude that no construction-specific mechanism is required for the temporal interpretation of the –ko construction.

description: While chirality imbalances are forbidden in conventional lattice systems, non-Hermiticity can effectively avoid the chiral-doubling theorem to facilitate 1D chiral dynamics. Indeed, such systems support unbalanced unidirectional flows that can lead to the localization of an extensive number of states at the boundary, known as the non-Hermitian skin effect (NHSE). Recently, a generalized (rank-2) chirality describing a 2D robust gapless mode with dispersion $ω=k_{x}k_{y}$ has been introduced in crystalline systems. Here we demonstrate that rank-2 chirality imbalances can be established in a non-Hermitian (NH) lattice system leading to momentum-resolved chiral dynamics, and a rank-2 NHSE where there are both edge- and corner-localized skin modes. We then experimentally test this phenomenology in a 2-dimensional topolectric circuit that implements a NH Hamiltonian with a long-lived rank-2 chiral mode. Using impedance measurements, we confirm the rank-2 NHSE in this system, and its manifestation in the predicted skin modes and a highly unusual momentum-position locking response. Our investigation demonstrates a circuit-based path to exploring higher-rank chiral physics, with potential applications in systems where momentum resolution is necessary, e.g., in beamformers and non-reciprocal devices.

description: The ensemble of Euclidean gluon field configurations represented by the domain wall network is considered. A single domain wall is given by the sine-Gordon kink for the angle between chromomagnetic and chromoelectric components of the gauge field. The domain wall separates the regions with self-dual and anti-self-dual fields. The network of the domain wall defects is introduced as a combination of multiplicative and additive superpositions of kinks. The character of the spectrum and eigenmodes of color-charged fluctuations in the presence of the domain wall network is discussed. The concept of the confinement-deconfinement transition in terms of the ensemble of domain wall networks is outlined. Conditions for the formation of thick domain wall junction during heavy ion collisions are discussed, and the spectrum of color charged quasiparticles inside the trap is evaluated. An important observation is the existence of the critical size $L_c$ of the trap stable against gluon tachyonic modes, which means that deconfinement can occur only in a finite region of space-time in principle. The size $L_c$ is related to the value of gluon condensate $\langle g^2F^2\rangle$.

Givenness and Maximize Presupposition
Creators: name: Kučerová, Ivona
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: Based on word order patterns in Czech, I argue that a cross-linguistically common partitioning of a sentence between given and new material is a result of an interplay of independently needed pragmatic notions: the Maximize Presupposition principle of Heim (1991) and presupposition failure. I formalize the intuition by introducing presuppositions by a freely insertable recursive operator which applies upwards and which adds to each successive argument an existential presupposition (cf. Sauer- land 2005). Movement in this approach is free but dispreferred and it is licensed only if it leads to an interpretation which would not be available otherwise (along the lines of Fox (2000, 1995); Reinhart (1995)). The resulting structure is licensed by the interfaces only if it satisfies Maximize presupposition and does not lead to presupposition failure.

description: We present a data-driven approach to learning surrogate models for amplitude equations, and illustrate its application to interfacial dynamics of phase field systems. In particular, we demonstrate learning effective partial differential equations describing the evolution of phase field interfaces from full phase field data. We illustrate this on a model phase field system, where analytical approximate equations for the dynamics of the phase field interface (a higher order eikonal equation and its approximation, the Kardar-Parisi-Zhang (KPZ) equation) are known. For this system, we discuss data-driven approaches for the identification of equations that accurately describe the front interface dynamics. When the analytical approximate models mentioned above become inaccurate, as we move beyond the region of validity of the underlying assumptions, the data-driven equations outperform them. In these regimes, going beyond black-box identification, we explore different approaches to learn data-driven corrections to the analytically approximate models, leading to effective gray box partial differential equations.

description: We developed an optimal Maxent model with exceptional performance to predict the current and future suitable areas for the invasive pest Lycorma delicatula worldwide. Our model results predicted that East Asia, central and eastern United States, and southern Europe are the main suitable areas under current environmental conditions. However, in future climate scenarios, the suitable areas for Lycorma delicatula were larger than the current ones, indicating a significant increase in the invasive potential of this pest. Furthermore, our results indicated a northward expansion trend of suitable areas. This study provides valuable insights into the risk of introducing Lycorma delicatula under both current and future conditions and can be used to develop appropriate pest management strategies.
Presuppositions in Processing: A Case Study of German auch
Creators: name: Schwarz, Florian
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper presents two experimental studies investigating the processing of presupposed content. Both studies employ the German additive particle auch (too). In the first study, participants were given a questionnaire containing bi-clausal, ambiguous sentences with ’auch’ in the second clause. The presupposition introduced by auch was only satisfied on one of the two readings of the sentence, and this reading corresponded to a syntactically dispreferred parse of the sentence. The prospect of having the auch-presupposition satisfied made participants choose this syntactically dispreferred reading more frequently than in a control condition. The second study used the self-paced-reading paradigm and compared the reading times on clauses containing auch, which differed in whether the presupposition of auch was satisfied or not. Participants read the clause more slowly when the presupposition was not satisfied. It is argued that the two studies show that presuppositions play an important role in online sentence comprehension and affect the choice of syntactic analysis. Some theoretical implications of these findings for semantic theory and dynamic accounts of presuppositions as well as for theories of semantic processing are discussed.

description: Electron scattering in the topological surface state (TSS) of the bulk-insulating topological insulator Bi$_{1.5}$Sb$_{0.5}$Te$_{1.7}$Se$_{1.3}$ was studied using quasiparticle interference observed by scanning tunneling microscopy. It was found that not only the 180$^{\circ}$ backscattering but also a wide range of backscattering angles of 100$^{\circ}$--180$^{\circ}$ is effectively prohibited in the TSS. This conclusion was obtained by comparing the observed scattering vectors with the diameters of the constant-energy contours of the TSS, which were measured for both occupied and unoccupied states using time- and angle-resolved photoemission spectroscopy. The unexpectedly robust protection from backscattering in the TSS is a good news for applications, but it poses a challenge to the theoretical understanding of the transport in the TSS.

In this paper, as a first step to regularizing VPD, we find general complete independent basis of VPD algebra. Especially, we find complete independent basis that give simple structure constants, where three area preserving diffeomorphism (APD) algebras are manifest. This implies that an algebra that regularizes VPD algebra should include three u(N) Lie algebras.

Almost There: The Meaning of almost
Creators: name: Penka, Doris
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: Modifiability by almost has been used as a test for the quantificational force of a DP without stating the meaning of almost explicitly. The aim of this paper is to give a semantics for almost applying across categories and to evaluate the validity of the almost test as a diagnosis for universal quantifiers. It is argued that almost is similar to other cross-categorial modifiers such as at least or exactly in referring to alternatives ordered on a scale. I propose that almost evaluates alternatives in which the modified expression is replaced by a value close by on the corresponding Horn scale. It is shown that a semantics for almost that refers to scalar alternatives derives the correct truth conditions for almost and explains selectional restrictions. At the same time, taking the semantics of almost seriously invalidates the almost test as a simple diagnosis for the nature of quantifiers.

We consider a list of representative benchmark scenarios with one or two non-vanishing RPV couplings. The photon has an energy $\mathcal{O}\left(0.1\right)-\mathcal{O}\left(1\right)$ TeV. We find a sensitivity reach for RPV couplings beyond the current bounds by orders of magnitude at \texttt{FASER} and \texttt{FASER2}.

description: Consciousness is supported by complex patterns of brain activity which are indicative of irreversible non-equilibrium dynamics. While the framework of stochastic thermodynamics has facilitated the understanding of physical systems of this kind, its application to infer the level of consciousness from empirical data remains elusive. We faced this challenge by calculating entropy production in a multivariate Ornstein-Uhlenbeck process fitted to fMRI brain activity recordings. To test this approach, we focused on the transition from wakefulness to deep sleep, revealing a monotonous relationship between entropy production and the level of consciousness. Our results constitute robust signatures of consciousness while also advancing our understanding of the link between consciousness and complexity from the fundamental perspective of statistical physics.

A novel two-dimensional phase bearing structural resembleance to a single MoS$_2$ layer is found to possess a lower total energy than low-buckled silicene and to be stable in terms of its phonon dispersion relations. A new set of cigar-shaped, nematic orbitals originating from the Si $sp^2$ orbitals realizes bonding with a 6-fold coordination of the inner Si atoms of the layer. The identification of these nematic orbitals advocates diverse Si bonding configurations different from those of C atoms.

description: Let $(M,g)$ be a compact, smooth Riemannian manifold and $\{u_h\}$ be a sequence of $L^2$-normalized Laplace eigenfunctions that has a localized defect measure $μ$ in the sense that $ M \setminus \text{supp}(π_* μ) \neq \emptyset$ where $π:T^*M \to M$ is the canonical projection. Using Carleman estimates we prove that for any real-smooth closed hypersurface $H \subset (M\setminus \text{supp} (π_* μ))$ sufficiently close to $ \text{supp}(π_* μ),$ and for all $δ>0,$ $$ \int_{H} |u_h|^2 dσ\geq C_δ\, e^{- [\, d(H, \text{supp}(π_* μ)) + \,δ] /h} $$ as $h \to 0^+$. We also show that the result holds for eigenfunctions of Schrödinger operators and give applications to eigenfunctions on warped products and joint eigenfunctions of quantum completely integrable (QCI) systems.
Forking Paths and Polarity Items Licensing
Creators: name: Panzeri, Francesca
Publisher: name: Proceedings of Sinn und Bedeutung

description: There is an elegant account, proposed by Beaver and Condoravdi (2003), that assumes that the temporal connectives before and after are converses (i.e., they are analyzed by means of a unified lexical schema), and that explains away their different logical and veridical behavior appealing to other factors. There is an elegant explanation that connects the licensing of Polarity Items to informational strengthening requirements: Polarity Items are viewed as existentials that lead to a widening of the domain of quantification, and they are predicted to be legitimate only when this widening leads to a stronger statement (roughly, in downward monotone contexts). My plan is to connect these two approaches – by proposing an amendment in the definition Beaver and Condoravdi presented for before and after that is meant to account also for their Polarity Items licensing behavior.

description: The classical structure-function (SF) method in fully developed turbulence or for scaling processes in general is influenced by large-scale energetic structures, known as infrared effect. Therefore, the extracted scaling exponents $ζ(n)$ might be biased due to this effect. In this paper, a detrended structure-function (DSF) method is proposed to extract scaling exponents by constraining the influence of large-scale structures. This is accomplished by removing a $1$st-order polynomial fitting within a window size $\ell$ before calculating the velocity increment. By doing so, the scales larger than $\ell$, i.e., $r\ge \ell$, are expected to be removed or constrained. The detrending process is equivalent to be a high-pass filter in physical domain. Meanwhile the intermittency nature is retained. We first validate the DSF method by using a synthesized fractional Brownian motion for mono-fractal processes and a lognormal process for multifractal random walk processes. The numerical results show comparable scaling exponents $ζ(n)$ and singularity spectra $D(h)$ for the original SFs and DSFs. When applying the DSF to a turbulent velocity obtained from a high Reynolds number wind tunnel experiment with $Re_λ\simeq 720$, the 3rd-order DSF demonstrates a clear inertial range with $\mathcal{B}_3(\ell)\simeq 4/5ε\ell$ on the range $10

Multiple Modals Construction

Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: Modal items of different semantic types can only be combined in a specific order. Epistemic items, for instance, cannot be embedded under deontic ones. I’ll argue that this fact cannot be explained by the current semantic theories of modality. A solution to this problem will be developed in an update semantics framework. On the semantic side, a distinction will be drawn between circumstantial information about the world and information about duties, whereas I’ll use Nuyts’ notion of m-performativity to account for certain use of the modal items.

description: The recently proposed fluctuation relation in unfolding forces [Phys. Rev. E ${\bf 84}$, $060101$(R) $(2011)$] is re-examined taking into account the explicit time dependence of the force distribution. The stretching of a tethered Rouse polymer is exactly solved and the ratio of the probabilities of positive to negative forces is shown to be an exponential in force. Extensive steered molecular dynamics simulations of unfolding of deca alanine peptide confirm the form of fluctuation relation proposed earlier, but with explicit correct time dependence of unfolding forces taken into account. From exact calculations and simulations, a linear dependence of the constant in the exponential of the fluctuation relation on average unfolding forces and inverse temperature is proposed.

description: In this work we study the long-lived post-merger gravitational wave signature of a boson-star binary coalescence. We use full numerical relativity to simulate the post-merger and track the gravitational afterglow over an extended period of time. We implement recent innovations for the binary initial data, which significantly reduce spurious initial excitations of the scalar field profiles, as well as a measure for the angular momentum that allows us to track the total momentum of the spatial volume, including the curvature contribution. Crucially, we find the afterglow to last much longer than the spin-down timescale. This prolonged gravitational wave afterglow provides a characteristic signal that may distinguish it from other astrophysical sources.

description: In recent times, technology has played a significant role in education, with artificial intelligence (AI), one of these technological tools, becoming an emerging topic in education. It has been of great concern to professionals and researchers in the fields of science and education. The growing and/or increasing power of this app in society and in the education sector, especially as it affects the teaching profession, or teachers, to be specific, is of great worry and/or a profound risk. Education has been the basis for all progressive nations, and teachers have also been the main part of this progress, as they remain at the helm of major instructional decisions and the management of any of these innovative ideas to improve the teaching-learning process. With advances in technology and constant technological innovations, teachers are constantly refusing to adopt or integrate any of these innovative technologies or ideas in the education system. Artificial intelligence has become one of these innovative ideas, and is currently an emerging topic in the education system in recent years, threatening the foundations of teachers or educators in recent times. This paper focused on the argument that teaching machines will or will not replace human teachers in the classroom. Therefore, the researchers hope to find out from the existing literature if artificial intelligence could, in reality, replace the job of teachers in the classroom or act as an enhancer for teachers in the entire education sector. The paper further discussed the merits of AI in the modern classroom. The need for IT literacy among teachers and students alike in contemporary education structures was also discussed. The paper finally looked into the teachers’ challenges against successful implementation of artificial intelligence teaching machines in the education process and made recommendations and suggestions for sequential improvements
The Present Perfect at the Semantics/Pragmatics Interface: American English and Brazilian Portuguese
Creators: name: Molsing, Karina Veronica
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: Modern theorists rarely agree on how to represent the categories of tense and aspect, making a consistent analysis for phenomena, such as the present perfect, more difficult to attain. It has been argued in previous analyses that the variable behavior of the present perfect between languages licenses independently motivated treatments, particularly of a morphosyntactic or semantic- syntactic nature (Giorgi & Pianesi 1997; Schmitt 2001; Ilari 2001). More specifically, the well- known readings of the American English (AE) present perfect (resultative, experiential, persistent situation, recent past (Comrie 1976)), are at odds with the readings of the corresponding structure in Brazilian Portuguese (BP), the ‘pretérito perfeito composto” (default iterativity and occasional duration (Ilari 1999)). Despite these variations, the present work, assuming a tense-aspect framework at the semantic-pragmatic interface, will provide a unified analysis for the present perfect in AE and BP, which have traditionally been treated as semantically divergent. The present perfect meaning, in conjunction with the aspectual class of the predicate, can account for the major differences between languages, particularly regarding iterativity and the “present perfect puzzle”, regarding adverb compatibility.

On Temporally Bounded Quantification over Eventualities
Creators: name: Móia, Telmo
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper focuses on different subtypes of constructions involving temporally bounded quantification, e.g. sequences like David visited Rome three times followed by temporal phrases as different as (i) last year, which defines a time interval; (ii) in less that two months, which defines an amount of time; and (iii) per month, which refers to a time unit. As for the first two types of temporal phrases, data will be presented which shows that they have specific linguistic properties in these quantifying contexts, and do not behave exactly as the locating or duration adverbials they are superficially identical with. The third type of phrases will receive special attention. Structures with frequency adverbials like n times per month will be analysed compositionally, separating the quantified component n times from the temporally binding phrase per month (whose role is comparable to that of adverbials (i) and (ii) in the relevant constructions). The data presented is mainly from Portuguese, although the issues at stake – the linguistic properties of temporally bounded quantification – are obviously relevant to parallel constructions in other languages.

Year: 2019

description: This paper discusses the semantics of the English particle man. It is shown that this particle does different things when used sentence-initially and sentence-finally. The sentence-initial use is further shown to separate into two distinct intonational types with different semantic content. A formal semantics is proposed for these types.

description: The a priori analysis (APA) is discussed as a tool to assess the reliability of grades in standard curricular courses. This unusual, but striking application is presented when teaching the section on data treatment of a Laboratory Course to illustrate the characteristics of the APA and its potential for widespread use, beyond the traditional Physics Curriculum. The conditions necessary for this kind of analysis are discussed, the general framework is set out and a specific example is given to illustrate its various aspects. Students are often struck by this unusual application and are more apt to remember the APA. Instructors may also benefit from some of the gathered information, as discussed in the paper.
