Language development is in the mind and action of the child. Plenary Address, Fourth International Congress for the study of Child Language, Lund, Sweden, July 1987

Child development

description: The theory of language development described here explicitly addresses the contents of the young language-learning child’s conscious states of mind, with the proposal that language is acquired to express contents of mind and to interpret what others have in mind. The theory is a mental theory of expression and interpretation, in contrast to theories centered on support from adults in the environment or on the instrumental function of language to get things done in the world. The major thrust of a theory of language development that takes such an Intentional stance is the emphasis it places on the mind and actions of the child in development. This mental perspective provides the foundation for the various functions of language, including but not limited to its social and instrumental functions. Preliminary results are presented from research in progress with 14 children and their mothers, who were observed every month beginning before they began to say words until they began to combine words in simple sentences. The practice of rich interpretation of children’s words and sentences in language acquisition research was extended to interpret what a child had in mind when expressing affect and saying words, with the children equated for language development, at First Words (FW) and a Vocabulary Spurt (VS), rather than age. The psychological attitudes and propositional contents attributed to their speech and affect expressions form the preliminary results of the studies described here.

description: No abstracts are to be cited without prior reference to the author.An important factor influencing fishers’ compliance with fisheries regulation is a feeling of legitimacy of the policy. Legitimacy includes belief that the management is based on reliable advice. This requires a two-way process rather than a one-way flow of information. We involve stakeholders in the development of biological models for Baltic Sea herring fishery and the evaluation of policy advice using these models. The study concentrates in factors behind the negative biomass trend and poor growth rates of the herring stocks. Alternative model structures are built based on current knowledge of the stakeholders. A “meta-model” is built as a synthesis of the different stakeholder models. This is compared to a model provided by biological research and discussed with the stakeholders. Differences between the views are analysed: how well the scientific model covers the views of the stakeholders, and how the inclusion and linking of additional variables help the stakeholders link the different risk components to their own argumentation? Using a model as an interactive forum can enhance common understanding about the fishery system and consensus about management actions. Participatory approach to modelling may reduce criticism about the use of models in natural resource policy advice where the assumptions and uncertainties are difficult to communicate. It may be a way to involve stakeholders in decision-making processes including a demand for increased transparency and understanding.
Beyond the pipe : participation and alternative water provision in underserved areas of Accra, Ghana
Creators: name: Morinville, Cynthia
Publisher: name: University of British Columbia
Year: 2012

description: Drinking water remains inaccessible for approximately 783 million people globally – an increasing portion of whom now live in cities. The incapability of municipal provision systems (both public and private) to adequately supply urban citizens means that for many of them water access is negotiated every day in places nowhere near a tap. Instead, points of access are located beyond the pipe, along informal delivery lines. This thesis aims to evaluate the potential of two alternative modes of provision in urban Accra –participatory water governance offering new points of access in underserved communities and small-scale private service providers producing sachet water. Through an exploration of the flows of water as it leaves the municipal mains, this thesis offers a qualitative account of water access in underserved areas in Accra, Ghana. Specifically, Chapter 2 examines participatory water governance in the form of Local Water Boards established throughout the last decade in several neighbourhoods of Accra. Through a discussion of participation’s limits, the chapter argues that a narrow approach to participation, less attentive to other multi-scalar political and social processes at play, undermines the possibilities to improve water access and foster more inclusive water governance in Accra. Chapter 3 offers an analysis of small-scale private service providers looking at the case of Accra’s flourishing sachet water industry –sachets are 500 ml bags of water manufactured locally and distributed throughout the city. The chapter argues that the sachet industry redefines water production and alters its distribution in Accra in a way unaccounted for by the small-scale private service providers literature. The sachet water industry in Accra alters the physical flows of water as well as the power relation vis-à-vis municipal authorities and as such has significant implications for water governance. This thesis is based on qualitative fieldwork including semi-structured interviews, field and participant observations, water user surveys, and document analysis conducted throughout two field seasons in Accra, Ghana (June to August 2011 and June to September 2012).

description: Geologic carbon sequestration has the potential to reduce greenhouse gas concentrations in the atmosphere. However, one barrier to large scale implementation is concern for water quality degradation from leakage of high CO₂ fluids into drinking water aquifers. The hydrogeochemical response to simulated CO₂ leakage was studied to estimate major and trace element release and to develop criteria for water quality monitoring and risk assessment. In this study, approximately 3100 L aquifer water enhanced with 1 atmosphere pressure CO₂ gas was injected into a fracture zone located at 362–366 m below the ground surface in a sandstone/siltstone/mudstone interbedded aquifer in the Newark Basin. This was followed by a 3–6 week long incubation and then continuous monitoring of the hydrogeochemistry in the pumped-back water samples. Relative to background conditions, the recovered aquifer water displayed a decrease of pH, increase of alkalinity, Ca, Mg and Si concentrations, decrease of sulfate and Mo concentrations, and increased concentrations of trace elements including Fe, Mn, Cr, Co, Ni, Cu, Zn, Rb, Sr, Ba and U. These changes in aquifer water geochemistry can be explained by (a) dissolution of silicate and carbonate minerals and (b) trace element release that appear to be dependent on pH and pCO₂ and affected by the altered redox conditions in the aquifer. Rapid and simultaneous changes of pH, specific conductance, major and trace metal release in aquifer water could be used as indicators of CO₂ leakage from geologic sequestration sites. Hydrogeochemical parameters including pH, total dissolved solids and trace elements, particularly Fe, Mn, and Zn, need to be monitored in compliance with the U.S. Environmental Protection Agency (EPA) drinking water regulations.

description: This paper investigates bright quantum-matter-wave solitons beyond the Gross-Pitaevskii equation (GPE). As proposals for interferometry and creating nonlocal quantum superpositions have been formed, it has become necessary to investigate effects not present in mean-field models. We investigate the effect of harmonic confinement on the internal degrees of freedom, as the ratio of zero-point harmonic oscillator length to classical soliton length, for different numbers of atoms. We derive a first-order energy correction for the addition of a harmonic potential to the many-body wave function and use this to create a variational technique based on energy minimization of this wave function for an arbitrary number of atoms, and include numerics based on diagonalization of the Hamiltonian in a basis of harmonic oscillator Fock states. Finally we compare agreement between a Hartree product ground state and the Bethe ansatz solution with a Gaussian envelope localizing the center of mass and show a region of good agreement.

description: Self-similarity may stem from two origins: the process' increments infinite variance and/or process' memory. The $b$-value of the Gutenberg-Richter law comes from the first origin. In the frame of natural time analysis of earthquake data, a fall of the b-value observed before large earthquakes reflects an increase of the order parameter fluctuations upon approaching the critical point (mainshock). The increase of these fluctuations, however, is also influenced from the second origin of self-similarity, i.e., temporal correlations between earthquake magnitudes. This is supported by observations and simulations of an earthquake model.

description: We provide an exact solution of the Efimov spectrum in ultracold gases within the standard two-channel model for Feshbach resonances. It is shown that the finite range in the Feshbach coupling makes the introduction of an adjustable three-body parameter obsolete. The solution explains the empirical relation between the scattering length a_- where the first Efimov state appears at the atom threshold and the van der Waals length l_vdw for open channel dominated resonances. There is a continuous crossover to the closed channel dominated limit, where the scale in the energy level diagram as a function of the inverse scattering length 1/a is set by the intrinsic length r* associated with the Feshbach coupling. Our results provide a number of predictions for non-universal ratios between energies and scattering lengths that can be tested in future experiments.

description: No abstracts are to be cited without prior reference to the author.In order to develop a new management plan for Baltic salmon fisheries the European Commission has asked for a comprehensive impact assessment. The resulting analysis comprised several studies carried out by scientists from respective disciplines. These included: biological and ecological assessment, economic analysis of the commercial fisheries sector and a separate socio-economic data analysis of the recreational fisheries, and, finally, a sociological impact assessment was conducted aimed at understanding stakeholder perspectives and possible commitment to a new management plan. In order to synthesize the findings from these disparate studies a Bayesian Belief Network (BBN) methodology is used. BBN is a tool that can support decision making by allowing a computation of utilities of different decisions in the light of diverse sources of evidence. Additionally, BBN provides a convenient way to summarise information in one model that represents the management problem that includes all of the evidence available. We demonstrate how this methodology can be used to support decision making in fisheries that relies not just on stock assessments but also on a broader range of expert opinion, data and research from ecological, economical and sociological fields.

description: The current financial crisis poses severe challenges for central bank policymaking; but the widely-used DSGE paradigm -- designed to analyse the control of inflation -- seems ill-suited to understanding the origins of the crisis or designing measures to resolve it. The relevant macroeconomic framework must surely include high leverage and overvalued collateral assets, where capital restructuring is the key to crisis resolution. The usual "bankruptcy" procedures for doing this are not designed to handle macro shocks hitting the whole economy: they would fail to internalise the price effects of asset "fire-sales" required to satisfy margin calls. We use a simple model of credit-constrained borrowers to show how "super" Chapter 11 procedures can play a crucial role in preventing asset price correction triggering widespread economic collapse. (Timely cuts in interest rates -- which act as transfers from lenders to borrowers -- will also help.) To cope with the financial shock, balance sheets need "restructuring": what about the microfoundations of conventional macroeconomics?

description: What does wise public policy toward panhandling look like? When a willing, reasonably well informed donor gives money to a panhandler, both are better off, and inequality goes down. Policy should encourage transactions like this. When a pedestrian is upset by a panhandler’s presence, does not give, and maybe even alters course, no one is better off and at least one person is worse off. Policy should discourage this kind of interaction. We examine an array of programs to deal with panhandling to see how well they encourage welfare-improving interactions and discourage welfare-reducing ones. Tentatively, credentialing programs are the most promising.
A phase field framework for capillary-induced fracture in unsaturated porous media: Drying-induced vs. hydraulic cracking

description: This manuscript introduces a unified mathematical framework to replicate both desiccation-induced and hydraulic fracturing in low-permeable unsaturated porous materials observed in experiments. The unsaturated porous medium is considered as a three-phase solid–liquid–gas effective medium of which each constituent occupies a fraction of the representative elementary volume. As such, an energy-minimization-based phase-field model (PFM) is formulated along with the Biot’s poroelasticity theory to replicate the sub-critical crack growth in the brittle regime. Unlike hydraulic fracturing where the excess pore liquid pressure plays an important role at the onset and propagation of cracks, desiccation cracks are mainly driven by deformation induced by water retention. Therefore, the wettability of the solid skeleton may affect the evolution of the capillary pressure (suction) and change the path-dependent responses of the porous media. This air–water–solid interaction may either hinder or enhance the cracking occurrence. This difference of capillary effect on crack growth during wetting and drying is replicated by introducing retention-sensitive degradation mechanisms in our phase field fracture approach. To replicate the hydraulic behaviors of the pore space inside the host matrix and that of the cracks, the path-dependent changes of the intrinsic permeability due to crack growth and porosity changes are introduced to model the flow conduit in open and closed cracks. Numerical examples of drying-induced and hydraulic fracturing demonstrate the capability of the proposed model to capture different fracture patterns, which qualitatively agrees with the fracture mechanisms of related experiments documented in the literature.

description: We present a catalogue of 2135 galaxy redshifts from the VLT LBG Redshift Survey (VLRS), a spectroscopic survey of z ~ 3 galaxies in wide fields centred on background quasi-stellar objects. We have used deep optical imaging to select galaxies via the Lyman-break technique. Spectroscopy of the Lyman-break galaxies (LBGs) was then made using the Visible Multi-Object Spectrograph (VIMOS), giving a mean redshift of z=2.79. We analyse the clustering properties of the VLRS sample and also of the VLRS sample combined with the smaller area Keck-based survey of Steidel et al. From the semiprojected correlation function, wp(σ) we find that the results are well fit with a single power-law model, with clustering scale lengths of r0=3.46+-0.41 and 3.83+-0.24 Mpc/h, respectively. We note that the corresponding combined ξ(r) slope is flatter than for local galaxies at γ = 1.5-1.6 rather than γ=1.8. This flat slope is confirmed by the z-space correlation function, ξ(s), and in the range 10

description: No abstracts are to be cited without prior reference to the author.Fisheries management often limits an effective and meaningful exchange of information and ideas between stakeholders and managers. Our objective was to develop a process that allows stakeholders to develop recommendations to improve the fishery through voluntary measures and provide management recommendations that they supported. We developed a “stakeholder-centered” process that facilitated explicit goal setting and iterative evaluation of options acceptable to stakeholders. An initial application involved angler, tournament, commercial, management, recreational industry, and conservation stakeholders for the southeastern U.S. king mackerel (Scomberomorus cavalla) fishery. The stakeholder workgroup developed objectives for the fishery, options that could be used to achieve the objectives, and performance measures to gauge whether objectives were reached. Objectives included traditional and non-traditional goals such as maintaining high and stable catches and retaining the opportunity to catch large fish, and options included voluntary changes in fishing practices and mandatory regulations. Stakeholders were an integral component in developing a model to allow them to compare how well their options met their objectives. Based on the results of the decision analysis, stakeholders developed a consensus suite of recommendations, including more conservative length and bag limits than those initially recommended by management. The immersion of stakeholders in reviewing the available science and developing the model led to recognition that more conservative management was necessary to achieve their objectives. This project demonstrated that stakeholders can be included in a meaningful participatory process that can improve fisheries management, but inclusion requires increased time and an effort to provide science without jargon or condescension

description: We study panhandling in Downtown Manhattan. Surprisingly few people panhandle there at any given moment: about 8-10 people on average at a busy time, in a small area with an economy the size of Latvia’s. The redevelopment of Ground Zero and the resulting surge in economic activity—including the opening of North America’s tallest building—changed where panhandlers operated within the neighborhood, but did not significantly increase panhandling overall. The response was muted because the labor supply of panhandlers appears to be inelastic. On the other hand, good places to panhandle are relatively abundant. Hence the benefits of the boom in economic activity accrued mainly to incumbent panhandlers themselves; as would the benefits of greater donor generosity.

description: This research essay analyzes the environmental Kuznets curve, the first hypothesis to make the correlation between economic development, environmental clean-up, and the Kuznets Curve. In essence, the EKC states that environmental quality deteriorates in the initial stages of a country’s economic development, but once a particular average income is reached that this trend will reverse and environmental degradation will begin to slow down considerably. Thus, rather than being a threat to the environment, economic growth would actually be the means to eventual environmental improvement. Although proponents of the EKC have shown some empirical evidence suggesting that rising income levels in developing countries can be advantageous rather than detrimental for the environment, this article demonstrates that there is no guarantee that economic growth will lead to an improved environment. More specifically, this essay proves that the notion that income growth by itself will be beneficial for the environment is fictitious, as a causal relationship between income and environmental quality cannot be consistently demonstrated.

description: Background: Phase-equivalent transformations (PETs) are well-known in quantum scattering and inverse scattering theory. PETs do not affect scattering phase shifts and bound state energies of two-body system but are conventionally supposed to modify two-body bound state observables such as the rms radius and electromagnetic moments. Purpose: In order to preserve all bound state observables, we propose a new particular case of PETs, a deuteron-equivalent transformation (DET-PET), which leaves unchanged not only scattering phase shifts and bound state (deuteron) binding energy but also the bound state wave function. Methods: The construction of DET-PET is discussed; equations defining the simplest DET-PETs are derived. We apply these simplest DET-PETs to the JISP16 $NN$ interaction and use the transformed $NN$ interactions in calculations of $^3$H and $^4$He binding energies in the No-core Full Configuration (NCFC) approach based on extrapolations of the No-core Shell Model (NCSM) basis space results to the infinite basis space. Results: We demonstrate the DET-PET modification of the $np$ scattering wave functions and study the DET-PET manifestation in the binding energies of $^3$H and $^4$He nuclei and their correlation (Tjon line). Conclusions: It is shown that some DET-PETs generate modifications of the central component while the others modify the tensor component of the $NN$ interaction. DET-PETs are able to modify significantly the $np$ scattering wave functions and hence the off-shell properties of the $NN$ interaction. DET-PETs give rise to significant changes in the binding energies of $^3$H (in the range of approximately 1.5 MeV) and $^4$He (in the range of more than 9 MeV) and are able to modify the correlation patterns of binding energies of these nuclei.

description: Although the fields of community development and historic preservation are independently successful, there is an increasing need for professionals from each field to collaborate for efficient urban development. By combining the community building aspects of community development and the sustainable practices of historic preservation, urban development endeavors become more sustainable for both the environment and the people in urban communities. The growing pertinence of both community developers and historic preservationists in urban development is shown through analysis of the practices of each field and case studies involving their collaboration.

description: No abstracts are to be cited without prior reference to the author.Regarding the straddling fish stocks, management is enforceable only in the framework of cooperation via bi- and multilateral agreements. The prerequisites and stability of international agreements has been analyzed using game theory in the literature. Influence of asymmetric information about fishing costs between countries harvesting the same fish stock has not yet received much attention. Gaps in the knowledge of economic performance of fishing fleets have strategic implications. They can be positive or negative depending on whether a country possesses or does not posses economic information, and whether information is asymmetric or asymmetric and uncertain. Asymmetric information creates problems in a non-cooperative fishery because a country can, by giving false information about fishing costs, manipulate the reaction of the other country not possessing equivalent information about the costs of its adversary. The analysis is parameterized for the North Sea herring fishery where the EU and Norway harvest the same resource. They regulate the fishery in cooperation via an EU/Norway agreement. Information asymmetry is considered as particular parameter sets in a deterministic empirical setting where country 1 has information of its own variable fishing costs but not about the costs of country 2. Country 2 has complete knowledge of the costs of both countries. In the setting we vary the actual fishing costs of country 2 and the costs that country 2 signals to country 1. We also analyze situation where country 2 does not have accurate information of its own costs. The total profits and profits of both countries are calculated using non-cooperative Nash equilibrium. Cost data have strategic value and there are incentives to conceal them in non-cooperative fishery. Country possessing perfect information will never gain the highest profits by signalling correct cost information to the other country. Instead, it will be rational to cheat and signal lower costs than the actual ones irrespective of cost asymmetry between the countries. The value of possessing perfect information is 20-40 million euros, depending on cost asymmetry, during a 10 year period. Another type of a case develops when a country has biased or uncertain knowledge of own fishing costs. In these situations, management schemes are likely to be suboptimal. Moreover, the probability of excessive fishing pressure is higher of the order of magnitude in the presence of asymmetric and uncertain fishing cost information, compared to case when cost information is asymmetric but not uncertain.

description: This photo essay illustrates a study on endeavors in a rural Japanese town with a declining population and discusses the future of rural society from a perspective of civic pride as well as sustainability. The population of the town of Gojome, located in Akita Prefecture of northern Japan, has halved from 20,025 in 1960 to 9,481 in 2015. Depopulation is often perceived as a half-empty glass, but we approached our study with the view that it is half-full. We discuss the issue through appreciative approaches by adopting the concept of “civic pride” as an alternative lens based on our empirical survey. The methodology adopted for this field survey include individual interviews with 126 respondents (consisting of 79 residents of Gojome and 47 individuals who were visiting the town) across different generations, 15 key informant interviews, drawings of their pride about the town by 34 sixth-graders of Gojome Elementary School, and observations. It was found that various generations of proud Gojome locals and non-locals have started to proactively participate in the process of bettering the town through various social, cultural, economic, and environmental activities. Based on our learning in Gojome town we conclude that, in the wake of rural depopulation, nurturing “civic pride” could potentially contribute to rural sustainability through entrusting the future of rural society to next generations.

description: Inversion symmetry is a very non-trivial discrete symmetry of Frobenius manifolds. It was obtained by Dubrovin from one of the elementary Schlesinger transformations of a special ODE associated to a Frobenius manifold. In this paper, we review the Givental group action on Frobenius manifolds in terms of Feynman graphs and obtain an interpretation of the inversion symmetry in terms of the action of the Givental group. We also consider the implication of this interpretation of the inversion symmetry for the Schlesinger transformations and for the Hamiltonians of the associated principle hierarchy.

description: Measurements of the $pp \to pK^+Λ$ reaction at $T_p$ = 2.28 GeV have been carried out at COSY-TOF. In addition to the $Λp$ FSI and $N^*$ resonance excitation effects a pronounced narrow structure is observed in the Dalitz plot and in its projection on the $pΛ$-invariant mass. The structure appears at the $pp \to $N$K^+Σ$ threshold and is interpreted as $Σ$N cusp effect. The observed width of 20 MeV/$c^2$ is substantially broader than anticipated from previous inclusive measurements. Angular distributions of this cusp structure are shown to be dissimilar to those in the residual $pK^+Λ$ channel, but similar to those observed in the $pK^+Σ^0$ channel.

description: The problem of particle creation from vacuum in a flat Robertson-Walker space-time is studied. Two sets of exact solutions for the Klein Gordon equation are given. Then the canonical method based on Bogoliubov transformation is applied to calculate the pair creation probability and the density number of created particles. Some particular cosmological models such as radiation dominated universe and Milne universe are discussed. For the both cases the vacuum to vacuum transition probability is calculated and the imaginary part of the effective action is extracted.

Vascular changes in spinal cord injured animals with repetitive episodes of autonomic dysreflexia

description: Spinal cord injury (SCI) is a devastating condition that not only leads to paralysis, but also causes dramatic changes in cardiovascular function. Individuals with cervical or high thoracic SCI commonly suffer from a life threatening condition known as autonomic dysreflexia (AD). AD is characterized by episodic hypertension─ an exaggerated sympathetic response triggered by irritating stimulus below the level of injury e.g. distended bladder. As a lifespan of SCI patients increases, cardiovascular-related illnesses become more prevalent. Recent studies suggest marked vascular dysfunction within the critical splanchnic vascular bed. Mesenteric arteries from rats with chronic high-thoracic SCI are hypersensitive to the α₁-adrenoceptor agonist PE. The hypersensitivity of splanchnic vascular bed in response to PE develops over time after SCI and may contribute to the development of AD. In this dissertation, I examined the morphological changes in peripheral vasculature following repetitive episodes of AD in animals with high SCI. I hypothesized that recurrent episodes of AD will trigger an inward eutrophic remodeling in peripheral resistance arteries of SCI rats. In this study, male Wistar rats with complete spinal cord transection at third (T3) thoracic segment were utilized. At 2 weeks after the injury, AD was induced in rats with T3 SCI using CRD. 4 weeks following injury superior mesenteric (SMA) arteries and primary branches (PMA) were collected from T3 SCI-only, T3+CRD and control uninjured rats. Morphological characteristics such as media thickness, lumen diameter, wall-to-lumen ratio and wall cross sectional area (CSA) of the arteries were evaluated. Results suggest that AD induced through CRD lead to structural remodeling of PMAs, but no changes were observed in SMAs of CRD group. Media thickness, wall-to-lumen ratio significantly increased in PMAs of CRD group; lumen diameter and CSA of PMAs in CRD did not change when compared to T3 SCI-only and uninjured groups. The data support eutrophic (no change in CSA) remodeling of PMAs in CRD group, but failed to show a reduction in lumen diameter (inward changes) of these arteries. The findings of the study highlight the underlying effect of AD on structural remodeling of vasculature following an injury.

description: Seasonal surface freshening of the Makassar Strait, the main conduit of the Indonesian Throughflow (ITF), is a key factor controlling the ITF. Here we present a 262 year reconstruction of seasonal sea-surface-salinity variability from 1742 to 2004 Common Era by using coral δ18O records from the central Makassar Strait. Our record reveals persistent seasonal freshening and also years with significant truncations of seasonal freshening that correlate exactly with South Pacific Convergence Zone (SPCZ) zonal events >4000 km to the east. During these events, the SPCZ dramatically rotates ~15° north to near the equator and stronger westward flowing South Pacific boundary currents force higher-salinity water through the Makassar Strait in February–May halting the normal seasonal freshening in the strait. By these teleconnections, our Makassar coral δ18O series provides the first record of the recurrence interval of these zonal SPCZ events and demonstrates that they have occurred on a semiregular basis since the mid-1700s.

description: No abstracts are to be cited without prior reference to the author.Long-term management or recovery plans are one of the main instruments in the Common Fisheries Policy (CFP). From the point of view of fisheries economics these plans may give fishermen a longer term perspective as compared to a management system with the possibility of heavily fluctuating quotas. The CFP demands impact assessments for all new management plans. The STECF assessed a few plans with a common approach by biologists and economists. These assessments show the problems with such an integrated approach especially with respect to modelling and long-term predictions. In the paper I describe the economics behind long-term management plans and the rationality of such plans from an economic viewpoint. Then I analyse the biological backgrounds of the harvest control rules of two plans from an economic perspective: the North Sea and the Baltic cod. After this overview on the contents of the plans I discuss the problems with integrated modelling work in impact assessments. So far economists mainly use the EIAA model for predictions on economic consequences of quota decisions. For the future analysis this model has to be extended to deal with impact assessments. Finally, I give an outlook on how an integrated modelling work may be organised referring to the new structure of the Institute of Sea Fisheries in Hamburg.

Constraining General Two Higgs Doublet Models by the Evolution of Yukawa Couplings

description: We study how general two Higgs doublet models can be constrained by considering their properties under renormalization group evolution of the Yukawa couplings. We take into account both the appearance of a Landau pole as well as off-diagonal Yukawa couplings leading to flavour changing neutral currents in violation with experimental constraints at the electroweak scale. We find that the latter condition can be used to limit the amount of Z2 symmetry breaking allowed in a given model.

description: Recent investigations of the contribution that intonation makes to overall utterance and discourse interpretation promise new sources of information for the investigation of long-time concerns in NLP.  In Hirschberg & Pierrehumber 1986 we proposed that intonational features such as phrasing, accent placement, pitch range, and tune represent important sources of information about the attentional and intentional structures of discourse.  In this paper we examine the particular contribution of choice of tune, or intonational contour, to discourse interpretation.
