description: The papers in this volume arise from various sources. Those by Ruth Finnegan, Maurizio Gnerre and Frank Seifart are written up versions of talks given at a workshop entitled What counts (and what doesn’t)? Data and methodology in language documentation held at the School of Oriental and African Studies (SOAS) on 4th-5th November 2006 and co-organised by Leora Bar-el and Friederike Luepke. Louise Ashmore’s contribution grows out of her MA dissertation submitted at SOAS in 2006, while David Nathan’s is an elaborated version of a paper presented at the International Conference on Austronesian Endangered Language Documentation held at Providence University, Taiwan, 5th-7th June 2007. Margaret Florey’s paper was presented orally at the Conference on Language Documentation and Linguistic Theory held at SOAS on 7th-8th December 2007 and appears in written form here for the first time. All the papers were anonymously refereed by colleagues at SOAS; I am particularly grateful for assistance with refereeing from Oliver Bond and David Nathan. Tom Castle did all the layout and formatting and looked after printing and binding, as well as designing the new cover that was established with LDD 4.

description: The design of X-band multi-cell RF structures for particle accelerators requires an accurate estimation of the sensitivity to the mechanical deformations induced by the surface power loss on the metallic walls. The prediction of these effects is important for conceiving a tuning strategy that assures the correct structure operation when integrated into the accelerator complex. An experimental technique is proposed for preliminary testing of the mechanical deformations caused by a thermal load that can generate in the RF cavity a temperature gradient profile as close as possible to the real one induced by the electromagnetic power loss. Because we want to find a method that can be easily and cheaply implemented in the laboratory, a thermal radiator with uniform heating power density, placed on the axis of the RF cavity, has been chosen as heating source. A multi-physics finite-element code (ANSYS) has allowed comparing the measured temperature gradients with the computed ones. The good agreement validates the application of the code, which has been extended to the joint solution of the electromagnetic and thermal problem. Thus the sensitivity to deformations can be directly evaluated.

description: We elucidate the feature of gravitational waves (GWs) from binary neutron star merger collapsing to a black hole by general relativistic simulation. We show that GW spectrum imprints the coalescence dynamics, formation process of disk, equation of state for neutron stars, total masses, and mass ratio. A formation mechanism of the central engine of short $γ$-ray bursts, which are likely to be composed of a black hole and surrounding disk, therefore could be constrained by GW observation.

Documenting grammatical tone using Toolbox: an evaluation of Buseman’s interlinearisation technique
Creators: name: McGill, Stuart
Publisher: name: Language Documentation and Description
Year: 2014

description: For tone languages, particularly those found in Africa, it is often the case that important grammatical distinctions depend solely on the occurrence of different tone patterns on a particular noun or verb. The goal of this paper is to consider how the grammatical contribution of such tone patterns should be represented in the annotations within documentary corpora. After introducing certain tone phenomena from Cicipu, a Benue-Congo language spoken in northwest Nigeria (section 2), I will challenge the view that it is not appropriate to make explicit the effects of tone patterns in interlinear annotations (section 3), and review a technique devised by Alan Buseman of the Summer Institute of Linguistics for handling tone using the software program Toolbox (section 4). Based on the evaluation of this technique as applied to a corpus of Cicipu texts (section 5), I suggest some recommendations for the future development of interlinearisation software (section 6). The technique devised by Alan Buseman is suggested as a compromise between more complex techniques such as Advanced Glossing which make detailed linguistic annotation possible at the expense of visual compactness and speed of processing, and simpler techniques which fail to capture the link between tone patterns and meanings at...

description: Stationary light pulses (SLPs), i.e., light pulses without motion, are formed via the retrieval of stored probe pulses with two counter-propagating coupling fields. We show that there exist non-negligible hybrid Raman excitations in media of cold atoms that prohibit the SLP formation. We experimentally demonstrate a method to suppress these Raman excitations and realize SLPs in laser-cooled atoms. Our work opens the way to SLP studies in cold as well as in stationary atoms and provides a new avenue to low-light-level nonlinear optics.

Filming languages: implications of indigenous video production for language maintenance in Mexico
Creators: name: Edwards, Catherine
Publisher: name: Language Documentation and Description
Year: 2014

description: This paper is an intervention into film studies from the point of view of language maintenance and revitalisation, to highlight the presence of indigenous languages in ‘subject-generated’ films. ‘Subject-generated’ is a term used by the visual anthropologist Ruby (2000) to identify films made by the ‘subjects’ of traditional ethnographic film. In Mexico, a similar meaning is conveyed by video indígena ‘indigenous video’, the term most often used in the present paper. Mexico is home to a vast number of indigenous languages, several grassroots indigenous filmmaking organisations, and a government with an official policy of intercultural education and media. Here the focus will be on the recent history and current situation of indigenous language community filmmaking in Mexico, though relevant examples from other parts of the world will also be included ... dialogue between relevant fields such as language documentation, visual anthropology, and language revitalisation will help indicate how scholarship can best support film and video production taking place among minority language speakers throughout the world. I therefore adopt a comparative and interdisciplinary approach, drawing upon research from several academic traditions and geographical areas, as well as on the films themselves and interviews with their producers.

Managing linguistic diversity in the church
Creators: name: Fast, Anicka
Publisher: name: Language Documentation and Description
Year: 2014

description: In this paper, I investigate perceptions of language utility held by church leaders, expatriate missionaries, and church members in Burkina Faso, in order to shed light on the complex use of language ideologies in a situation of ongoing intra-church conflict. I also relate the language attitudes expressed both directly and indirectly by research participants to other discourses and ideologies of endangerment and authenticity circulating in both academic and ecclesiastical circles. By moving beyond the simple description of language attitudes to an explanation of their relation to structures of power and interest, I hope to exemplify a “demythologise[ed] sociolinguistics” which sees the use of language ideology and the expression of language attitudes as “a social practice in its own right” (Cameron 1997:64). I also intentionally situate myself as a ‘critically engaged’ researcher (Speed 2006:67) who shares a moral framework with research participants (Dobrin 2005, Fast 2007a).

description: [1] Persistent melting (e.g., continuing for more than three days or for one consecutive day and night) is mapped in Antarctica (1987–2006) using night- and day-time Special Sensor Microwave Imager brightness temperatures (Tb) at 19.35 GHz, horizontal polarization. Snowmelt is indicated when Tb and relative daily difference exceed threshold values, respectively Tc and ΔT, computed for each pixel and year, or when both daytime and nighttime Tb exceed Tc. Results from an electromagnetic model suggest that the minimum detectable liquid water content ranges between 0.2 and 0.5%, in volume. We find that melting areas have been moving inland since 1987. A first-time extensive melting (1987–2006) is detected over the Transantarctic Mountains on January 2005, 875 Km inland and 2000 m above sea level. Melting extent and index have been decreasing over Antarctica, since 1987, although either positive and negative trends are observed from a sub-continental scale analysis.
Study of Electron Beams Induced by Polarised Excimer Laser Beams

description: We report on the photoemission of electrons from a GaAs cathode illuminated by a circular polarised laser beam. The maximum output current intensity was 28 mA with 8.8 mJ laser energy. The quantum yield was 1.5x10^{-7}. This value was limited either to the GaAs work function or the optical transitions involved during the polarised light interaction. Measurements with a no-polarised laser beam were also performed.

description: We report measurements of ablation rates of the bottom of two supraglacial lakes and of temperatures at different depths collected during the summers of 2010 and 2011 in west Greenland. To our knowledge, this is the first time that such data sets are reported and discussed in the literature. The measured ablation rates at the bottom of the two lakes are of the order of ∼6 cm/day, versus a rate of ∼2.5–3 cm/day in the case of bare ice of surrounding areas. Though our measurements suggest the presence of a vertical temperature gradient, it is not possible to draw final conclusions as the measured gradient is smaller than the accuracy of our temperature sensors. In-situ measurements are compared with the results of a thermodynamic model forced with the outputs of a regional climate model. In general, the model is able to satisfactorily reproduce the measured quantities with RMSE of the order of 3–4 cm for the ablation and ∼1.5°C in the case of water temperature. Our results confirm that the ablation at the bottom of supraglacial lakes plays an important role on the overall lake volume with the ablation in the case of ice covered by a lake being 110–135% of that over bare ice at nearby locations. Beside ice sheet hydrological implications, melting at the bottom of a supraglacial lake might affect estimates of lake volume from spaceborne visible and near-infrared measurements.

description: Informed consent is crucial in research, but potential participants may not all speak the same language, posing questions that have not been examined concerning decisions by institutional review boards (IRBs) and research ethics committees’ (RECs) about the need for researchers to translate consent forms and other study materials. Sixty US IRBs (every fourth one in the list of the top 240 institutions by The National Institutes of Health funding) were contacted, and leaders (eg, chairs) from 34 (response rate=57%) and an additional 12 members and administrators were interviewed. IRBs face a range of problems about translation of informed consent documents, questionnaires and manuals—what, when and how to translate (eg, for how many or what proportion of potential subjects), why to do so and how to decide. Difficulties can arise about translation of specific words and of broader cultural concepts regarding processes of informed consent and research, especially in the developing world. In these decisions, IRBs weigh the need for autonomy (through informed consent) and justice (to ensure fair distribution of benefits and burdens of research) against practical concerns about costs to researchers. At times IRBs may have to compromise between these competing goals. These data, the first to examine when and how IRBs/RECs require researchers to translate materials, thus highlight a range of problems with which these committees struggle, suggesting a need for further normative and empirical investigation of these domains, and consideration of guidelines to help IRBs deal with these tensions.
Tensor power spectrum with holonomy corrections in LQC

description: In this paper we consider tensor perturbations produced at a bounce phase in presence of the holonomy corrections. Here bounce phase and holonomy corrections originate from Loop Quantum Cosmology. We re-derive formulas for the corrections for the model with a scalar field content. Background dynamics with a free scalar field and multi-fluid potential are considered. Since the considerations are semi-classical effects of quantum fluctuations of the background dynamics are not taken into account. Quantum and classical back-reaction effects are also neglected. To find spectrum of the gravitational waves both analytical approximations as well as numerical investigations were performed. We have found analytical solutions on super-horizontal and sub-horizontal regimes and derived corresponding tensor power spectra. Also occupation number $n_{\bf k}$ and parameter $Ω_{\text{gw}}$ were derived in sub-horizontal limit, leading to its extremely low present value. Final results are numerical power spectra of the gravitational waves produced in presence of quantum holonomy corrections. The obtained spectrum has two UV and IR branches where $\mathcal{P}_T \propto k^2$, however with the different prefactors. Spectrum connecting these regions is in the form of oscillations. We have found good agreement between numerical spectrum and this obtained from the analytical model. Obtained spectrum can be directly applied as initial conditions for the inflationary modes. We mention possible resulting observational features of the CMB in particular B-type polarization.

Language documentation and pedagogy for endangered languages: a mutual revitalisation
Creators: name: Nathan, David
name: Fang, Meili
Publisher: name: Language Documentation and Description
Year: 2014

description: This paper explores how language endangerment, documentation, and revitalisation can be connected by identifying ways in which documentation can support language teaching and learning. Up to now, documentation has brought a new focus to linguistics by attending to the nature of the data that supports linguistic research. There is a complementary – but largely unexplored – path of working out how documentary linguistics can support language learning and revitalisation. Right now, the methodologies of documentary linguistics for data collection and representation are barely innovative or distinctive for endangered (as opposed to healthy) languages. If the discipline is to continue in its role as the principal response by linguists to language endangerment, it needs to clarify its specialisations and to further develop the methodologies used in pursuit of them.

title: Female voice and agency in film adaptations
Creators: name: Houtman, Coral
Publisher: name: University of Kent
Year: 2003

description: This thesis examines the claim that women write differently from men, and employs a methodology which compares a range of film adaptations with the books from which they are taken. The thesis explores the agency and voice of four novels and their film adaptations, 1 using techniques derived from narrative analysis where "the implied author" is the agency responsible for the overall relationship of narration (story telling) to narrative (story) and is also the "voice" - the rhetoric of the text. Psychoanalysis forms a conceptual framework for exploring the performance of sexual difference in these works authored by women, but directed by men, and for investigating psychological thrillers, where issues of sexuality and desire are dramatised, particularly in relationship to death and the fear of obliteration. The thesis considers the 'gendering' of the texts - how they construe sexual difference, through fantasy and through desire. Lacan's discourse analysis enables a further investigation of the possibilities of hysterical agency driving the narrative; anxiety and uncertainty over gender and sexual difference driving the needs of the characters and the narration, and therefore, by implication, the real author or authors. It also discusses whether this hysteria is performed differently by men and women, due to their different subject positions, and thereby creates a potential link between the implied author of the text, and the gender of the real author(s). The real author, the agent of the text, cannot, in this formulation, be regarded as either sovereign or unified. Rather, I theorise, following Althusser and the performative theory of Judith Butler, that authorial voice is an interpellation. That is, they are called up and placed into a network of norms and parameters where they assume the agency of authorship. Agency is therefore contingent and traumatic, and a text which creates a less causal and individualistic performance of narrative agency might also be able to explore the relationship of gender and sexual difference to agency without slipping into the Freudian flaw of making anatomy destiny. I consider Mrs. Dalloway, as a poetic, non-linear form, a multi-voiced and multi-determined narrative, which creates a very rich female portrait of its central protagonist and a selfconsciously female narrative voice. In addressing the traumas and hysterias of sexual difference, and relating them to the analogous traumas created through the abuse of power in other realms of life, Mrs. Dalloway provides an alternative way of thinking about sexual difference, gender and agency, one that privileges creativity, reparation and the need to come to terms with trauma, whether one is male or female.

description: Coherent pion production in low energy neutrino reactions is discussed in the framework of the partially conserved axial vector current theory (PCAC). The role of lepton mass effects in suppressing production of positively charged pions is discussed. Instead of using models of pion nucleus scattering, the available data on pion carbon scattering are implemented for an analysis of the PCAC prediction. Our results agree well with the published upper limits for positively charged production but are much below the recent MiniBooNE result for neutral pion production.

description: Existing forward snow emission models (SEMs) are limited by knowledge of both the temporal and spatial variability of snow microphysical parameters, with grain size being the most difficult to measure or estimate. This is due to the sparseness of in situ data and the lack of simple operational parameterizations for the evolution of snowpack properties. This paper compares snow brightness temperatures predicted by three SEMs using, as inputs, predicted snowpack characteristics from the Variable Infiltration Capacity (VIC) model. The latter is augmented by a new parameterization for the evolution of snow grain morphology and density. The grain size dynamics are described using a crystal growth equation. The three SEMs used in the study are the Land Surface Microwave Emission Model (LSMEM), the Dense Media Radiative Transfer (DMRT) model, and the Microwave Emission Model of Layered Snowpacks (MEMLS). Estimated brightness temperature is validated against the satellite [Advanced Microwave Scanning Radiometer for Earth Observing System (AMSR-E)] data at two sites from the Cold Land Processes Experiment (CLPX), conducted in Colorado in the winter of 2003. In addition, a merged multimodel estimate, based on Bayesian model averaging, is developed and compared to the measured brightness temperatures. The advantages of the Bayesian approach include the increase in the mean prediction accuracy as well as providing a nonparametric estimate of the error distributions for the brightness temperature estimates.

description: We report the results of a comparative analysis focusing on grain size, mineralogical composition and spectral reflectance values (400–2500 nm) of cryoconite samples collected from Jakobshavn Isbrae, West Greenland, and Canada Glacier, McMurdo Dry Valleys, Antarctica. The samples from the Greenland site were composed of small particles clumped into larger rounded agglomerates, while those from the site in Antarctica contained fragments of different sizes and shapes. Mineralogical analysis indicates that the samples from Jakobshavn Isbrae contained a higher percentage of quartz and albite, whereas those from Canada Glacier contained a higher percentage of amphibole, augite and biotite. Spectral measurements confirmed the primary role of organic material in reducing the reflectance over the measured spectrum. The reflectance of the samples from the Antarctic site remained low after the removal of organic matter because of the higher concentration of minerals with low reflectance. The reflectance of dried cryoconite samples in the visible region was relatively low (e.g. between ∼0.1 and ∼0.4) favouring increased absorbed solar radiation. Despite high reflectance values in the shortwave infrared region, the effect of the presence of cryoconite is negligible at infrared wavelengths where ice reflectance is low.

description: We theoretically show how the spin orientation of a single magnetic adatom can be controlled by spin polarized electrons in a scanning tunneling microscope configuration. The underlying physical mechanism is spin assisted inelastic tunneling. By changing the direction of the applied current, the orientation of the magnetic adatom can be completely reversed on a time scale that ranges from a few nanoseconds to microseconds, depending on bias and temperature. The changes in the adatom magnetization direction are, in turn, reflected in the tunneling conductance.

description: The air content of glacial firn determines the effect and attribution of observed changes in ice surface elevation, but is currently measurable only using labor-intensive ground-based techniques. Here a novel method is presented for using radar sounding measurements to decompose the total thickness of floating ice shelves into thicknesses of solid ice and firn air (or firn water). The method is applied to a 1997/98 airborne survey of Larsen Ice Shelf, revealing large spatial gradients in air content that are consistent with existing measurements and local meteorology. The gradients appear to be governed by meltwater-induced firn densification. We find sufficient air in Larsen C Ice Shelf for increased densification to account for its previously observed surface lowering, and the rate of lowering superficially agrees with published trends in melting. This does not preclude a contribution to the lowering from oceanic basal melting, but a modern repeat of the survey could conclusively distinguish atmosphere-led from ocean-led change. The technique also holds promise for the calibration of firn-density models, derivation of ice thickness from surface elevation measurements, and calculation of the sea-level contribution of changes in grounded-ice discharge.

Language management for endangered languages: the case of Navajo
Creators: name: Spolsky, Bernard
Publisher: name: Language Documentation and Description
Year: 2014

description: In this paper I outline an approach to building a theory of language management and its application to endangered languages. As I see it, language management is one of the three interconnected components of language policy (see Sallabank, this volume): the other two are language practices and language beliefs. To clarify how this works, I will illustrate the model with the case of Navajo, which is the second largest Native American tribe (after Cherokee) in the United States but whose language is not unreasonably considered to be endangered (Lee and McLaughlin 2001). The dominant impression left by our analysis of the Navajo situation is that the shift from Navajo to English is mainly supported by such language management as exists on the Reservation and elsewhere. Only a major change of policy, with concerted grassroots and government support for active language management, is likely to reverse this situation.

Dynamics of Vesicle Formation from Lipid Droplet: Mechanism and Controllability

description: A coarse-grained model developed by Marrink et al. [J. Phys. Chem. B 111, 7812 (2007)] is applied to investigate vesiculation of lipid [dipalmitoylphosphatidylcholine (DPPC)] droplets in water. Three kinds of morphologies of micelles are found with increasing lipid droplet size. When the initial lipid droplet is smaller, the equilibrium structure of the droplet is a spherical micelle. When the initial lipid droplet is larger, the lipid ball starts to transform into a disk micelle or vesicle. The mechanism of vesicle formation from a lipid ball is analyzed from the self-assembly of DPPC on the molecular level, and the morphological transition from disk to vesicle with increasing droplet size is demonstrated. Importantly, we discover that the transition point is not very sharp, and for a fixed-size lipid ball, the disk and vesicle appear with certain probabilities. The splitting phenomenon, i.e., the formation of a disk/vesicle structure from a lipid droplet, is explained by applying a hybrid model of the Helfrich membrane theory. The elastic module of the DPPC bilayer and the smallest size of a lipid droplet for certain formation of a vesicle are successfully predicted.

description: A combined analysis of remote sensing observations, regional climate model (RCM) outputs and reanalysis data over the Greenland ice sheet provides evidence that multiple records were set during summer 2012. Melt extent was the largest in the satellite era (extending up to ∼97% of the ice sheet) and melting lasted up to ∼2 months longer than the 1979–2011 mean. Model results indicate that near surface temperature was ∼3 standard deviations (σ) above the 1958–2011 mean, while surface mass balance (SMB) was ∼3σ below the mean and runoff was 3.9σ above the mean over the same period. Albedo, exposure of bare ice and surface mass balance also set new records, as did the total mass balance with summer and annual mass changes of, respectively, −627 Gt and −574 Gt, 2σ below the 2003–2012 mean. We identify persistent anticyclonic conditions over Greenland associated with anomalies in the North Atlantic Oscillation (NAO), changes in surface conditions (e.g., albedo, surface temperature) and preconditioning of surface properties from recent extreme melting as major driving mechanisms for the 2012 records. Less positive if not increasingly negative SMB will likely occur should these characteristics persist.

description: Asteroids can be considered as sources of contamination of point sources and also sources of confusion noise, depending whether their presence is detected in the image or their flux is under the detection limit. We estimate that at low ecliptic latitudes, ~10,000--20,000 asteroids/sq. degree will be detected with an E-ELT like telescope, while by the end of Spitzer and Herschel missions, infrared space observatories will provide ~100,000 serendipitous asteroid detections. The detection and identification of asteroids is therefore an important step in survey astronomy.

description: Within the framework of the MAP and RAPHAEL projects, airborne experimental campaigns were carried out by the IFAC group in 1999 and 2000, using a multifrequency microwave radiometer at L, C and X bands (1.4, 6.8 and 10 GHz). The aim of the experiments was to collect soil moisture and vegetation biomass information on agricultural areas to give reliable inputs to the hydrological models. It is well known that microwave emission from soil, mainly at L-band (1.4 GHz), is very well correlated to its moisture content. Two experimental areas in Italy were selected for this project: one was the Toce Valley, Domodossola, in 1999, and the other, the agricultural area of Cerbaia, close to Florence, where flights were performed in 2000. Measurements were carried out on bare soils, corn and wheat fields in different growth stages and on meadows. Ground data of soil moisture (SMC) were collected by other research teams involved in the experiments. From the analysis of the data sets, it has been confirmed that L-band is well related to the SMC of a rather deep soil layer, whereas C-band is sensitive to the surface SMC and is more affected by the presence of surface roughness and vegetation, especially at high incidence angles. An algorithm for the retrieval of soil moisture, based on the sensitivity to moisture of the brightness temperature at C-band, has been tested using the collected data set. The results of the algorithm, which is able to correct for the effect of vegetation by means of the polarisation index at X-band, have been compared with soil moisture data measured on the ground. Finally, the sensitivity of emission at different frequencies to the soil moisture profile was investigated. Experimental data sets were interpreted by using the Integral Equation Model (IEM) and the outputs of the model were used to train an artificial neural network to reproduce the soil moisture content at different depths.
Audio responsibilities in endangered languages documentation and archiving

description: Documentary linguistics (also called ‘language documentation’) focuses on data, and how data is acquired, represented, presented, and preserved, in contrast to the analytical and theoretical concerns of much of linguistics (Austin 2006, Austin and Grenoble 2007). And since many endangered languages are not written, the majority of this documentary data is audio. In turn, this raises new and interesting questions, such as: what audio data needs to be collected to count as a record of a language that is likely to disappear? Are standard corpus concepts of coverage and balance applicable to endangered language documentations? How can quality be measured? For what purposes and by whom will the data be used? For those of us concerned with the evolution of documentary linguistics, there are four key audio-related issues. The first is audio quality ... The second issue is the role and nature of the symbolic data that accompanies audio. The third issue is what we call mobilisation: the practical development of resources and products that make use of collected data to serve purposes such as language revitalisation (Nathan 2006). The fourth issue, protocol, arises from the fact that audio directly captures and represents individuals in a way that written data...

description: The duration of melting in 2011 was above average over much of Greenland, lasting up to ~30 days longer than the 1979–2010 average. Areas along the west and northwest coasts experienced the largest positive anomalies in the number of days when melting occurred (Fig. 5.10). The number of melting days in 2011 estimated from spaceborne passive microwave observations (Tedesco 2007) did not, however, break the previous record set in 2010 (Tedesco et al. 2011); 2011 ranked sixth, after 2010, 2007, 1998, 2002, and 2005.
