Authors: Huang Shiu-Ming , Huang Shih-Jhe , Hsu Ching , Wadekar Paritosh V. , Yan You-Jhih , Yu Shih-Hsun , Chou Mitch
Published: July 2017

The carrier transport characteristics of Sb2Se2Te topological insulators were investigated, after exposure to different levels of nitrogen gas. The magnetoresistance (MR) slope for the Sb2Se2Te crystal increased by approximately 100% at 10 K after 2-days of exposure. The Shubnikov-de Haas (SdH) oscillation amplitude increased by 30% while oscillation frequencies remained the same. MR slopes and the mobilities had the same dependency on temperature over a wide temperature range. All measured data conformed to a linear correlation between MR slope and mobility, supporting our hypothesis that the MR increase and the SdH oscillation enhancement might be caused by mobility enhancement induced by adsorbed N2 molecular.

Published: July 2017

Myeloid differentiation protein 1 (MD1) has been implicated in numerous pathophysiological processes, including immune regulation, obesity, insulin resistance, and inflammation. However, the role of MD1 in cardiac remodelling remains incompletely understood. We used MD1-knockout (KO) mice and their wild-type littermates to determine the functional significance of MD1 in the regulation of aortic banding (AB)-induced left ventricular (LV) structural and electrical remodelling and its underlying mechanisms. After 4 weeks of AB, MD1-KO hearts showed substantial aggravation of LV hypertrophy, fibrosis, LV dilation and dysfunction, and electrical remodelling, which resulted in overt heart failure and increased electrophysiological instability. Moreover, MD1-KO-AB cardiomyocytes showed increased diastolic sarcoplasmic reticulum (SR) Ca2+leak, reduced Ca2+transient amplitude and SR Ca2+content, decreased SR Ca2+-ATPase2 expression, and increased phospholamban and Na+/Ca2+-exchanger 1 protein expression. Mechanistically, the adverse effects of MD1 deletion on LV remodelling were related to hyperactivated CaMKII signalling and increased impairment of intracellular Ca2+homeostasis, whereas the increased electrophysiological instability was partly attributed to exaggerated prolongation of cardiac repolarisation, decreased action potential duration alternans threshold, and increased diastolic SR Ca2+leak. Therefore, our study on MD1 could provide new therapeutic strategies for preventing/treating heart failure.
Dopamine 2 Receptor Activation Entrains Circadian Clocks in Mouse Retinal Pigment Epithelium
Authors: Baba Kenkichi , DeBruyne Jason P. , Tosini Gianluca
Published: July 2017

Many of the physiological, cellular, and molecular rhythms that are present within the eye are under the control of circadian clocks. Experimental evidence suggests that the retinal circadian clock, or its output signals (e.g., dopamine and melatonin), may contribute to eye disease and pathology. We recently developed a retinal pigment ephithelium (RPE)-choroid preparation to monitor the circadian clock using PERIOD2 (PER2)::LUC knock-in mouse. In this study we report that dopamine, but not melatonin, is responsible for entrainment of the PER2::LUC bioluminescence rhythm in mouse RPE-choroid. Dopamine induced phase-advances of the PER2::LUC bioluminescence rhythm during the subjective day and phase-delays in the late subjective night. We found that dopamine acts exclusively through Dopamine 2 Receptors to entrain the circadian rhythm in PER2::LUC bioluminescence. Finallly, we found that DA-induced expression of core circadian clock genes Period1 and Period2 accompanied both phase advances and phase delays of the RPE-choroid clock, thus suggesting that – as in other tissues – the rapid induction of these circadian clock genes drives the resetting process. Since the RPE cells persist for the entire lifespan of an organism, we believe that RPE-choroid preparation may represent a new and unique tool to study the effects of circadian disruption during aging.

Published: July 2017

The realization of room-temperature processes is an important factor in the development of flexible electronic devices composed of organic materials. In addition, a simple and cost-effective process is essential to produce stable working devices and to enhance the performance of a smart material for flexible, wearable, or stretchable-skin devices. Here, we present a soft friction transfer method for producing aligned polymer films; a glass substrate was mechanically brushed with a velvet fabric and poly(3-hexylthiophene) (P3HT) solution was then spin-coated on the substrate. A P3HT film with a uniaxial orientation was obtained in air at room temperature. The orientation factor was 17 times higher than that of a film prepared using a conventional friction transfer technique at a high temperature of 120 °C. In addition, an oriented film with a thickness of 40 nm was easily picked up and transferred to another substrate. The mechanism for orientation of the film was investigated using six experimental methods and theoretical calculation, and was thereby attributed to a chemical process, i.e., cellulose molecules attach to the substrate and act as a template for molecular alignment.

English Verb Accuracy of Bilingual Cantonese–English Preschoolers
Authors: Rezzonico Stefano , Goldberg Ahuva , Milburn Trelani , Belletti Adriana , Girolametto Luigi
Published: July 2017

Purpose

Knowledge of verb development in typically developing bilingual preschoolers may inform clinicians about verb accuracy rates during the 1st 2 years of English instruction. This study aimed to investigate tensed verb accuracy in 2 assessment contexts in 4- and 5-year-old Cantonese–English bilingual preschoolers.

Method

The sample included 47 Cantonese–English bilinguals enrolled in English preschools. Half of the children were in their 1st 4 months of English language exposure, and half had completed 1 year and 4 months of exposure to English. Data were obtained from the Test of Early Grammatical Impairment (Rice & Wexler, 2001) and from a narrative generated in English.

Results

By the 2nd year of formal exposure to English, children in the present study approximated 33% accuracy of tensed verbs in a formal testing context versus 61% in a narrative context. The use of the English verb BE approximated mastery. Predictors of English third-person singular verb accuracy were task, grade, English expressive vocabulary, and lemma frequency.

Conclusions

Verb tense accuracy was low across both groups, but a precocious mastery of BE was observed. The results of the present study suggest that speech-language pathologists may consider, in addition to an elicitation task, evaluating the use of verbs during narratives in bilingual Cantonese–English bilingual children.
An Online Telepractice Model for the Prevention of Voice Disorders in Vocally Healthy Student Teachers Evaluated by a Smartphone Application
Authors: Grillo Elizabeth U.
Published: July 2017

This article describes the Global Voice Prevention Model (GVPM) facilitated with student teachers at West Chester University and the VoiceEvalU8 smartphone application (app) used to assess the effectiveness of the GVPM. Twenty-one participants completed 1 of 3 conditions (i.e., in-person GVPM, telepractice GVPM, and control). The in-person and telepractice conditions ran for 4 weeks during fall 2016, with 1 week dedicated to vocal education and vocal hygiene and 3 weeks spent in vocal training. The control condition ran for 1 week and included only vocal education and vocal hygiene. The VoiceEvalU8 app was used at pre- and post-condition twice a day for 5 days to record acoustic, perceptual, and aerodynamic voice measures. The study is ongoing; therefore, preliminary acoustic results for fundamental frequency (F0) and jitter% are presented from pre- to post-condition. During spring 2017, the participants were student teaching and using the VoiceEvalU8 app to record the voice measures before and after teaching all day. A new group of participants will be enrolled fall 2017 for selection into 1 of the 3 conditions and then continue on to student teaching spring 2018.
The Measurement and Effects of Vocal Load in Singing Performance. How Much Singing Can a Singer Sing if a Singer Can Sing Songs?
Authors: Phyland Debra
Published: July 2017

Singing as both an art form and physical activity demands a level of health and skill fitness to meet performance demands. The determination of performance fitness relies on performers' self-evaluations of their vocal capacity for performance, based, amongst other factors, on the current vocal status and ability to manage the associated vocal load. Measurement of load and the impact on the vocal mechanism is complex and influenced by many intrinsic and extrinsic factors. Researchers have attempted to quantify vocal load effects by measuring physical impact stress on the vocal folds, self-reported perceived exertion, and/or clinical evaluation of physiologic, acoustic, or perceptual changes. Most studies have been conducted in laboratory rather than in performance contexts and studies on singers are substantially lacking. Heavy vocal load has been causally associated with the development of voice disorders, although the exact relationship and thresholds for acquiring laryngeal pathology require further elucidation, and little is also known about the development of voice disorders among singers. Further understanding of the short-term and cumulative effect on the vocal folds of performing as a singer and the nature and prevalence of voice problems among singers is crucial to the determination of appropriate prevention and therapeutic management.
Location‐aided channel tracking and downlink transmission for HST massive MIMO systems
Authors: Zhang Cheng , Zhang Jing , Huang Yongming , Yang Luxi
Published: July 2017

In massive multiple‐input multiple‐output (MIMO) high‐speed train (HST) wireless communication systems (WCS), due to the large‐dimension and rapidly time‐varying property, channel tracking rather than conventional channel estimation is more feasible. Due to the non‐linear channel variation, the channel is first decomposed into sub‐channels with different angle of departure. By exploiting the property of near line of sight (LoS) and location information, Kalman filtering is used to track the channel by predicting and modifying the channel gain of the LoS sub‐channel. To further improve the tracking performance, a location‐based sequentially optimal beam pattern design is proposed. Since placing pilot beams for many receive antennas with different locations in time or frequency division manner costs much system resource, the authors further propose a low‐complexity grouping algorithm based on location. Finally, two transmission designs based on the proposed channel tracking scheme and the location only, respectively, are introduced. Simulations validate the efficiency of the authors' proposed tracking scheme and the corresponding transmission design, which shows the importance of location information and channel tracking in massive MIMO HST‐WCS.
Joint LDPC and physical‐layer network coding with incremental phase pre‐rotation for two‐way relaying
Authors: Jiang Ming , Sha Xiaoshi , Zhao Chunming
Published: July 2017

To obtain a robust physical‐layer network coding (PLNC) for two‐way relaying system, the authors propose a low‐density parity‐check (LDPC) coded PLNC scheme with phase pre‐rotation to combat the carrier phase asynchronous in the multiple access stage. At two users, each modulation symbol is rotated according to a predefined incremental phase without the knowledge of carrier phase difference. Decoding simulation and numerical analysis are carried out to evaluate this joint LDPC and PLNC scheme with phase pre‐rotation. Simulation results show that this strategy can achieve a significant improvement and a good trade‐off between performance and complexity. Protograph‐based extrinsic information transfer analysis demonstrates the proposed scheme is robust, which is consistent with the simulation results.
Consensus of discrete‐time linear multi‐agent systems with event‐based dynamic feedback scheme
Authors: Zhu Wei , Pu Huizhu , Wu Qiuxuan
Published: July 2017

The consensus problem of discrete time multi‐agent systems with linear dynamic models is investigated. To reduce the controller update times and communication among agents, an event‐based dynamic feedback scheme is proposed. For each agent, the controller update instants are determined by a state‐dependent threshold. It is shown that the controller update for each agent is only dependent on its own event times. Some sufficient conditions are obtained for consensus. Observing the current states of its neighbour agents as well as its own state at every discrete‐time is also avoided. Furthermore, certain conditions are given to exclude the Zeno‐like behaviour of the triggering time sequence. Finally, a numerical example is given to illustrate the efficiency of the proposed control strategy.
Hadoop‐based framework for big data analysis of synchronised harmonics in active distribution network
Authors: Cao Zijian , Lin Jin , Wan Can , Song Yonghua , Taylor Gareth , Li Maozhen
Published: July 2017

Synchronised harmonic analysis that utilises GPS signals to synchronise harmonic measurements enables advanced power quality analysis in smart grid. However, it is difficult to put this promising technology into practice due to an extremely high requirement on data storage and processing. To overcome this problem, this study presents a novel Hadoop‐based framework for big data analysis of synchronised harmonics in distribution networks. The proposed framework facilitates harmonic data processing associated with data storage and advanced analysis based on big data techniques. Under this framework, a big matrix multiplication algorithm based on MapReduce programming model solving the harmonic state estimation problem is deployed in the stage of data processing. A MapReduce‐based harmonics distortion calculation is implemented as an advanced analysis for harmonics. Comprehensive numerical studies are carried out to analyse the characteristics of the proposed algorithm and verify the effectiveness of the proposed framework.
Robust multi‐objective PQ scheduling for electric vehicles in flexible unbalanced distribution grids
Authors: Knezović Katarina , Soroudi Alireza , Keane Andrew , Marinelli Mattia
Published: July 2017

With increased penetration of distributed energy resources and electric vehicles (EVs), different EV management strategies can be used for mitigating adverse effects and supporting the distribution grid. This study proposes a robust multi‐objective methodology for determining the optimal day‐ahead EV charging schedule while complying with unbalanced distribution grid constraints. The proposed methodology considers partially competing objectives of an EV aggregator and the respective distribution system operator, and applies a fuzzy‐based mechanism for obtaining the best‐compromise solution. The robust formulation effectively considers the errors in the electricity price forecast and its influence on the EV schedule. Moreover, the impact of EV reactive power support on objective values and technical parameters is analysed both when EVs are the only flexible resources and when linked with other demand response programmes. The method is tested on a real Danish unbalanced distribution grid with 35% EV penetration to demonstrate the effectiveness of the proposed approach. It is shown that the proposed formulation guarantees an optimal EV cost as long as the price uncertainties are lower than the aggregator's conservativeness degree, and that EV reactive power improves local conditions without significantly affecting the EV cost.

Published: July 2017

We present an analysis pipeline that enables the recovery of reliable information for all four Stokes parameters with high accuracy. Its novelty relies on the effective treatment of the instrumental effects even before the computation of the Stokes parameters, contrary to conventionally used methods such as that based on the Müller matrix. For instance, instrumental linear polarization is corrected across the whole telescope beam and significant StokesQandUcan be recovered even when the recorded signals are severely corrupted by instrumental effects. The accuracy we reach in terms of polarization degree is of the order of 0.1–0.2%. The polarization angles are determined with an accuracy of almost 1°. The presented methodology was applied to recover the linear and circular polarization of around 150 active galactic nuclei, which were monitored between July 2010 and April 2016 with the Effelsberg 100-m telescope at 4.85 GHz and 8.35 GHz with a median cadence of 1.2 months. The polarized emission of the Moon was used to calibrate the polarization angle measurements. Our analysis showed a small system-induced rotation of about 1° at both observing frequencies. Over the examined period, five sources have significant and stable linear polarization; three sources remain constantly linearly unpolarized; and a total of 11 sources have stable circular polarization degreemc, four of them with non-zeromc. We also identify eight sources that maintain a stable polarization angle. All this is provided to the community for future polarization observations reference. We finally show that our analysis method is conceptually different from those traditionally used and performs better than the Müller matrix method. Although it has been developed for a system equipped with circularly polarized feeds, it can easily be generalized to systems with linearly polarized feeds as well.

Authors: Santos Roberto , Cupello Viviane , Polinati José Emilio , Paredes Leonardo , Gaffrée Gustavo
Published: July 2017

Secondary enophthalmos caused by an untreated orbital blowout fracture can cause esthetic and functional disturbances. The esthetic defect is manifested by sinking of the superior sulcus and the hypophthalmic globe. Functional impairment of the eye can usually be a common complaint with restriction of eye motion and diplopia. Early diagnosis followed by repair of surgically correctable fractures is the most acceptable procedure. Failure in the primary treatment may cause scar contraction and fat atrophy. The aim of this paper is to report a case of a late treatment of blowout orbital floor fracture with secondary enophthalmos using titanium mesh and buccal fat pad graft.

Impaired Metabolism of Selenomethionine in Graves’ Disease: A Biokinetics Study of Soft Gel Capsule Formulation
Authors: Duntas Leonidas , Boutsiadis Anastasios , Tsakris Athanasios
Published: July 2017

Patients with Graves’ disease are known to have low selenium (Se) status, Se supplementation resulting in clinical and biochemical improvement. Selenomethionine (SeMet) in a new soft gel capsule formulation was used in a pilot study in 6 patients with acute Graves’ disease and low selenium levels (61.3±12.9 μg/l) before and in 4/6 patients 3 months after combined treatment with methimazole and SeMet 200 μg/day (113.3±46.3 μg/l), as well as in 6 euthyroid controls (82±11.8 μg/l). The biokinetics were studied following ingestion of 200 μg SeMet (single dose) soft gel capsule, Se serum concentrations being measured at various time points within 24 h. Se levels rose variably in all patients and controls. While levels peaked in all subjects following 8 h of intake, the increase was somewhat slower in acute hyperthyroidism as compared to 3 months later when these patients had been rendered euthyroid, this possibly due to derangement of Se storage capacity by SEPP or increased requirements in the acute phase of the disease, leading to depletion of the trace element. The compound was shown to be bioavailable and safe and patients treated for 3 months exhibited higher Se levels at the different time points. These findings are of major importance for sufferers of GD since they indicate that early Se supplementation, with its beneficial antioxidant impact on inflammatory activity, could slow, or possibly even forestall, the clinical progression of the disease.
A high throughput instrument to measure mechanical losses in thin film coatings
Authors: Vajente G. , Ananyeva A. , Billingsley G. , Gustafson E. , Heptonstall A. , Sanchez E. , Torrie C.
Published: July 2017

Brownian thermal noise generated by mechanical losses in thin film coatings limits the sensitivity of gravitational wave detectors, as well as several high precision metrology experiments. Improving the sensitivity of the next generation of gravitational wave detectors will require optical coatings with significantly reduced mechanical losses. In this paper, we describe a system that we developed to measure the mechanical loss angle of thin film coatings deposited on fused silica substrates. The novelty of this system resides in the capability of parallel measurement of up to four samples and the ability to simultaneously probe all the resonant modes of each sample. This high throughput measurement system allows the exploration of a large number of deposition and material parameters, which can be tuned to achieve low loss coatings.

Published: July 2017

The impact of cross-field motion of high-Z dust grains on their shielding by ablation cloud in edge plasmas of tokamaks is analyzed. The modification of the existing high-Z dust shielding theory is developed, which takes the dust motion effects into account. It is shown that the cross-field motion can lead to a large factor increase of the dust ablation rate, as compared to the previous model. It is also shown that the motion effects take place when the dust cross-field velocity exceeds a threshold value. The dependencies of the dust ablation flux on the dust velocity and of the threshold velocity on the dust size and the ambient plasma temperature are obtained.

We prepared κ-Al2O3-type structured AlxFe2-xO3 films in the range of x = 0 – 1.70 deposited on SrTiO3(111) substrates and investigated their crystal structures and magnetic properties. All films could be stabilized in the κ-Al2O3-type orthorhombic phase, and the lattice parameters were found to be monotonically decreased with an increase in the Al content. Néel temperature of AlxFe2-xO3 films was found to decrease with an increase in Al content, until the Al1.70Fe0.30O3 film showed paramagnetic behavior. On the other hand, saturation magnetization showed a maximum 0.79 μB/Fe at 10 K in the Al0.91Fe1.09O3 film, manifesting the preferential occupation of Al in the tetrahedral site. Cross sectional TEM observation has revealed the columnar growth of AlxFe2-xO3 films with an average width of ∼10 nm on the bottom layer that may have a similar cation arrangement with a bixbyite-type structure.
Resonant spectrum method for characterizing Ba0.5Sr0.5TiO3 based high overtone bulk acoustic wave resonators
Authors: Sandeep Kongbrailatpam , Pundareekam Goud J. , James Raju K. C.
Published: July 2017

This letter reports the use of the resonant spectrum method to characterize a high overtone bulk acoustic wave resonator (HBAR) which has a thin film ferroelectric BaSrTiO3 (BSTO) active layer on a YAG substrate. The HBAR works on the principle of electric field induced piezoelectricity of the thin film ferroelectric BSTO and exhibits switching functionality. From the parallel and series resonant frequencies of each of the multiple peaks in the frequency spectrum of the HBAR, the distribution of spacing of parallel resonance frequency and the distribution of effective coupling coefficient are studied and parameters like acoustic wave velocity, electromechanical coupling coefficient, elastic constant, and density for the thin film are determined. The influence of dc bias voltages on the distribution of the effective coupling coefficient and the electromechanical coupling coefficient is also reported. This letter also establishes the relationship between the relative tunability of the device capacitance and the electromechanical coupling coefficient.

We report the efficient coherent photon scattering from a semiconductor quantum dot embedded in a pillar microcavity. We show that a surface acoustic wave can periodically modulate the energy levels of the quantum dot but has a negligible effect on the cavity mode. The scattered narrow-band laser is converted into a pulsed single-photon stream, displaying an anti-bunching dip characteristic of single-photon emission. Multiple phonon sidebands are resolved in the emission spectrum, due to the absorption and emission of vibrational quanta in each scattering event.
The effect of hole transporting layer in charge accumulation properties of p-i-n perovskite solar cells
Authors: Galatopoulos Fedros , Savva Achilleas , Papadas Ioannis T. , Choulis Stelios A.
Published: July 2017

The charge accumulation properties of p-i-n perovskite solar cells were investigated using three representative organic and inorganic hole transporting layer (HTL): (a) Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS, Al 4083), (b) copper-doped nickel oxide (Cu:NiOx), and (c) Copper oxide (CuO). Through impedance spectroscopy analysis and modelling, it is shown that charge accumulation is decreased in the HTL/perovskite interface, between PEDOT:PSS to Cu:NiOx and CuO. This was indicative from the decrease in double layer capacitance (Cdl) and interfacial charge accumulation capacitance (Cel), resulting in an increase to recombination resistance (Rrec), thus decreased charge recombination events between the three HTLs. Through AFM measurements, it is also shown that the reduced recombination events (followed by the increase in Rrec) are also a result of increased grain size between the three HTLs, thus reduction in the grain boundary area. These charge accumulation properties of the three HTLs have resulted in an increase to the power conversion efficiency between the PEDOT:PSS (8.44%), Cu:NiOx (11.45%), and CuO (15.3%)-based devices.
Optical characterization of polar HfO2 nanoparticles in the mid- and far-infrared

Published: July 2017

Monoclinic HfO2 nanoparticles with nominal diameters of 9, 30, and 45 nm are characterized using transmission and reflection spectroscopy from the mid- to far-infrared. Phonon modes are identified in the measured spectra and agree with previously reported values in HfO2 thin films and density functional perturbation theory calculations. An anomaly in both reflection and transmission is observed at 556 cm−1 that is not attributed to the optical phonon modes. Numerical models predict a localized surface phonon polariton mode near this frequency, and we attribute the anomaly to coupling to this surface mode. The results of this work suggest that HfO2 nanoparticles could enable engineered optical properties in new mid- and far-infrared materials and devices.
Synthesis of system outcomes for a grazing-management experiment in temperate native pastures
Authors: Badgery W. B. , Michalk D. L.
Published: July 2017

Increasing the intensity of grazing management from continuous grazing or set-stocking to intensive rotational grazing has been proposed as a way of improving the profitability and environmental outcomes for native pasture-based grazing systems in the high-rainfall zone (HRZ) of southern Australia. The present paper synthesised the results and outcomes of eight papers covering different aspects of a grazing-system study investigating the intensity of grazing management at Panuara (33°27ʹS, 148°56ʹE), 25 km south-west of Orange, New South Wales. The systems analysis covered soils and soil water, pastures, animal production, profitability and business risk by using a combination of field experiments and biophysical modelling. The experimental approach, engagement with stakeholders and the potential impact of the research outcomes are discussed; as are the future directions for grazing system research. Increasing the intensity of grazing management from a 1- to a 20-paddock system resulted in a 21% higher pasture growth, 22% higher stocking rate and 20% higher lamb production per hectare. However, modelling demonstrated that seasonal variability had a greater impact on profitability than did the management system, and whole-farm profitability of the 20-paddock system was lower than that of the 1- and 4-paddock systems due to higher infrastructure costs. Pasture stability was associated with a high perennial grass content (>70%), and a stocking rate of 4.2 ewes/ha for continuous grazing or 5.3 ewes/ha for intensive rotational grazing limited the potential for degradation events. Advantages were identified in fencing and managing production zones, with different production potential within a farm, to improve utilisation across the landscape and efficiency of fertiliser use. The farming-system approach successfully integrated field research with pre- and post-experimental modelling, and with strategic input from an advisory group containing farmers, researchers and advisors, to develop a full understanding of the impact, at a system level, of increasing the intensity of grazing management in the HRZ.
The future of historical sociolinguistics?
Authors: Säily Tanja , Nurmi Arja , Palander-Collin Minna , Auer Anita
Published: July 2017

In this chapter we discuss the current achievements of historical sociolinguistics and highlight new insights provided by the contributions in the volume. Taking the essay by Nevalainen (2015) as a starting point, we consider the themes of crossing boundaries and bridging gaps between different levels of analysis and different paradigms, as well as proposing new paths for historical sociolinguistics as part of the wider field of digital humanities.
Ireland in British parliamentary debates 1803–2005
Authors: Baker Helen , Brezina Vaclav , McEnery Tony
Published: July 2017

This study investigates the changing contexts in which the word ireland appears in the Hansard Corpus of British parliamentary debates. It combines the use of two statistical techniques for analysis and visualization of historical data (Meaning Fluctuation Analysis and sparklines) with a more qualitative examination of concordance lines from the corpus. The full historical context of the patterns observed in the parliamentary data is also provided. We show that the sophisticated corpus techniques have the ability to draw our attention to important points in the time series, which need to be further investigated within the context of the larger historical picture.
Discord in eighteenth-century genteel correspondence
Authors: Nevala Minna , Sairio Anni
Published: July 2017

This chapter studies representations of discord in the correspondence of eighteenth-century English gentry. The study aims at charting various ways in which the upper classes negotiated conflict situations and cases where norms of society were challenged, by mapping the social meaning of relevant labels according to the three themes of discord, disgrace, and disorder. The methodological starting point is in Nevalainen and Tissari’s (2010) study of the shifting cultural keywords courtesy, civility, and politeness, which we also study here along with the lexemes discord, disgrace, embarrassment, mortification, and shame. The results show that civility, politeness, and shame all function as tools for social control and critical evaluation of self and others.
“A graphic system which leads its own linguistic life”?
Authors: Kaislaniemi Samuli , Evans Mel , Juvonen Teo , Sairio Anni
Published: July 2017

Traditional accounts of the history of English spelling are primarily based on printed texts. According to them, English orthography developed from great diversity in Late Middle English to modern standard spelling by 1800. Studies have also revealed a split between public and private spelling practices. This paper charts the history of epistolary spelling in Early Modern English using the Corpus of Early English Correspondence. We counter potential editorial interference in the corpus by two methods. First, we focus on frequent variables; and second, we use smaller, manuscript-based resources to verify our findings. The results reveal, for the first time, long-term trends in the history of English private spelling.
Revisiting weak ties
Authors: Laitinen Mikko , Lundberg Jonas , Levin Magnus , Lakaw Alexander
Published: July 2017

This article makes use of big and rich present-day data to revisit the social network model in sociolinguistics. This model predicts that mobile individuals with ties outside a home community and subsequent loose-knit networks tend to promote the diffusion of linguistic innovations. The model has been applied to a range of small ethnographic networks. We use a database of nearly 200,000 informants who send micro-blog messages on Twitter. We operationalize networks using two ratio variables; one of them is a truly weak tie and the other a slightly stronger one. The results show that there is a straightforward increase of innovative behavior in the truly weak tie network, but the data indicate that innovations also spread under conditions of stronger networks, given that the network size is large enough. On the methodological level, our approach opens up new horizons in using big and often freely available data in sociolinguistics, both past and present.
