Interventions of Speakers of Polish and British Parliaments in the light of politeness theory
Authors: Brzozowska Dorota , Chłopicki Władysław 
Published: January 2021

Abstract
The present study attempts to analyze the interventions of Speakers of Polish and British Parliaments in the selected exchanges from 2018 to 2019 in terms of discourse-sensitive politeness theory advanced by Jonathan Culpeper. He proposes to use three types of impoliteness that affect three types of interlocutors’ faces via a range of impoliteness strategies. In the analyses we consider the linguistic, personal, and cultural as well as political context of the exchanges against the background of the unique, historically rooted institutional circumstances, with a special emphasis on the role of different physical contexts of respective Parliamentary chambers. We emphasize the discursive nature and continuum of (im)polite/(in)appropriate behaviors. In conclusion, the study falls back on Brown and Levinson’s tradition, argued not to be incompatible with Culpeper’s system, and confirms the existence of largely negative and largely positive politeness cultures, emphasizing the prevalence of Polish formal, impersonal, sometimes also affective impoliteness in contrast to the British somewhat more person-oriented, coercive impoliteness.

Predicting Contract Participation in the Mekong Delta, Vietnam: A Comparison Between the Artificial Neural Network and the Multinomial Logit Model
Authors: Dang Huy Duc , Pham Thuyen Thi 
Published: January 2021

Abstract
The research aims of this study are bi-fold: to study factors influencing the uptake of contract farming (CF) and to compare the predicting power of the artificial neural network model (ANN) and the Multinomial Logit Model (MNL) on predicting CF participation in the Mekong Delta, Vietnam. ANN and MNL were employed to analyze on the basis of the transaction cost theory. To validate the ANN, a 10-fold cross-validation procedure was applied to avoid model overfitting. The sensitivity analysis of ANN was used to elicit the magnitude of the correlation between predictors. Multicollinearity was examined with all VIFs lower than two. Among predictors, the most influential roles of the cooperatives and the extension agents/services in supporting CF participation are reported. Also, farmers who conduct frequent access to the market incline to participate in CF. Risk perceptions and preferences are dissimilar across domains, which are also mainly interpreted that risk-averse farmers tend to opt for CF as an effective solution to risks perceived. Thus, heterogeneous approaches should be tailored to promote CF. The findings suggest that MNL outperforms ANN in terms of accuracy percentage and mean absolute error (MAE). However, this result should not be generalized base on the constraint of the data threshold as articulated in the study. The sensitivity analysis of ANN and the estimation results of the MNL relatively agreed on the importance of model predictors. This study is the first to investigate the impacts of the domain-specific risk perceptions and attitudes on CF and also contribute to the debate over the performance between the conventional econometric models versus machine learning techniques.
The Effect of Rapid Structural Change on Workers
Authors: Weigt Eva 
Published: January 2021

Abstract
This paper deals with the question how workers’ labour market and non-monetary outcomes are impacted by a negative sector-specific labour demand shock. This issue is analysed in a setting of rapid structural change that happened in Eastern Germany after the fall of the Berlin Wall in 1989. The sector-specific labour demand shock can be assumed to be exogenous to other worker characteristics as it was not anticipated and as career planning was highly restricted in the GDR. Using survey data from the German Socio-Economic Panel (SOEP), I find considerable and partly persistent losses in labour market outcomes of workers from declining compared to booming industries. Life satisfaction of workers from declining industries is decreased in the short run whereas the probability to move to the West and to identify with a left-wing political party is increased merely in the longer run.
The Nonlinear Dynamics of Corporate Bond Spreads: Regime-Dependent Effects of their Determinants
Authors: Fischer Henning , Stolper Oscar 
Published: January 2021

Abstract
This paper studies the behavior of corporate bond spreads during different market regimes between 2004 and 2016. Applying a Markov-switching vector autoregressive (MS-VAR) model, we document that the dynamic impact of spread determinants varies substantially with market conditions. In periods of high volatility, systematic credit risk—rather than interest rate movements—contributes to driving up spreads. Moreover, while market-wide liquidity risk is not priced when volatility is low, it becomes a crucial factor during stress periods. Our results challenge the notion that spreads predominantly capture credit risk and suggest it must be reassessed during periods of financial distress.
Trust, Trustworthiness, and Age: Experimental Evidence
Authors: Lukas Moritz , Nöth Markus 
Published: January 2021

Abstract
Based on an incentivized non-anonymous trust game with 230 elementary school pupils aged between 6 and 11 years, we investigate the development of trust and trustworthiness across age groups. Trust increases with age, thereby increasing the profits of both the trustor and the trustee. The trustee keeps most of the profits. These results replicate the findings of Sutter and Kocher (2007) in that trust increases with age and trustworthiness exists in all age groups that are examined in our study; however, the amounts transferred between subjects in our experiment are substantially higher, a result which is likely to be driven by the non-anonymity in our setting.
A finite element method for degenerate two-phase flow in porous media. Part I: Well-posedness
Authors: Girault Vivette , Riviere Beatrice , Cappanera Loic 
Published: January 2021

Abstract
A finite element method with mass-lumping and flux upwinding is formulated for solving the immiscible two-phase flow problem in porous media. The method approximates directly the wetting phase pressure and saturation, which are the primary unknowns. The discrete saturation satisfies a maximum principle. Stability of the scheme and existence of a solution are established.
A finite element method for degenerate two-phase flow in porous media. Part II: Convergence
Authors: Girault Vivette , Riviere Beatrice , Cappanera Loic 
Published: January 2021

Abstract
Convergence of a finite element method with mass-lumping and flux upwinding is formulated for solving the immiscible two-phase flow problem in porous media. The method approximates directly the wetting phase pressure and saturation, which are the primary unknowns. Well-posedness is obtained in [J. Numer. Math., 29(2), 2021]. Theoretical convergence is proved via a compactness argument. The numerical phase saturation converges strongly to a weak solution in L
2 in space and in time whereas the numerical phase pressures converge strongly to weak solutions in L
2 in space almost everywhere in time. The proof is not straightforward because of the degeneracy of the phase mobilities and the unboundedness of the derivative of the capillary pressure.
Schur complement spectral bounds for large hybrid FETI-DP clusters and huge three-dimensional scalar problems
Authors: Dostál Zdeněk , Brzobohatý Tomáš , Vlach Oldřich 
Published: January 2021

Abstract
Bounds on the spectrum of Schur complements of subdomain stiffness matrices with respect to the interior variables are key ingredients of the convergence analysis of FETI (finite element tearing and interconnecting) based domain decomposition methods. Here we give bounds on the regular condition number of Schur complements of ‘floating’ clusters arising from the discretization of 3D Laplacian on a cube decomposed into cube subdomains. The results show that the condition number of the cluster defined on a fixed domain decomposed into m × m × m cube subdomains connected by face and optionally edge averages increases proportionally to m. The estimates support scalability of unpreconditioned H-FETI-DP (hybrid FETI dual-primal) method. Though the research is most important for the solution of variational inequalities, the results of numerical experiments indicate that unpreconditioned H-FETI-DP with large clusters can be useful also for the solution of huge linear problems.

Published: January 2021

AbstractWe propose a perfectly square lattice photonic crystal fiber (PCF) which shows high birefringence and negative dispersion. To set up high asymmetry in the core, dual line imperfection is considered where the fill fraction ratio and defect air hole diameter exhibit significant impact on dispersion and birefringence. Numerical analyses of guiding properties of the proposed PCF are done using finite element method with perfectly matched layer boundary condition from 1.2 to 1.8 μm wavelength. The optimized square lattice PCF presents high birefringence of 2.48 × 10−2and dispersion of −777.66 (ps/nm.km) at 1.55 μm wavelength. In addition, the proposed PCF offers ultra-low confinement and insertion loss at 1.55 μm wavelength. Moreover, −0.45 (ps/nm2.km) dispersion slope and 0.0045 nm−1relative dispersion slope are observed at 1.55 μm wavelength. Additionally, the proposed PCF maintains dispersion and birefringence variation of ±30 (ps/nm.km) and ±0.00001 between 1.5 and 1.6 μm wavelength ranges, respectively. Furthermore, the proposed PCF shows high quality factor and low bit error rate at 10 dBm input power. We believe the proposed square lattice PCF can be deployed in wavelength division multiplexing based optical fiber transmission system for wide-band dispersion compensation.

Abstract
In the current era of data communication everyone deals with the huge amount of data in form of text, audio, video and different other formats in which everyone want a secure and higher bandwidth channel to transmit and receive so, only the optical channel provides the solution of above said problem. The only difficulty with the existing model that the data from electrical domain first converted in form of light (optical domain) at the transmission end while after receiving the data at the receiver end it will be further converted in form of electrical signal for extracting the message. This type of conversion from one domain to other gives the energy loss. In the current research article, we proposed a model of optical processor which transmit and receive the data without conversion which provides an energy efficient optical technology. By adding reversibility, heat bender can be further reduced. In this manuscript, an arithmetical logic unit has been created, a photonic reversible complete subtractor and an irregular logic portal. SOA-MZI structure is the basic component of the architecture. The method is mainly carried out by the semiconductor Amplifier, using nonlinear properties such as cross-gain modulation and cross-phase modulation. The efficiency deciding factor for the whole system is 21.23 and 53.27 dB in the average extinction ratio. The cost of the arithmetic logic unit optically constructed is 9.

Published: January 2021

Abstract
The communication network based on the optical system requires more precise and efficient devices and equipment. Optical ring resonator is a versatile device used as a filter, delay line, add/drop multiplexer, switch, sensor and analyzer etc. We modelled the new symmetrical quadrature optical ring resonator (SQORR) and proposed four different topologies architecture for the multiple optical ring resonator. The performance of the proposed symmetrical quadrature optical ring resonator is assessed using regression based machine learning (ML) approach utilizing an Artificial neural network (ANN) with various checks are done to validate the approximations like error histogram, time series response, error autocorrelation, input-error correlation and mean-square-error (MSE). The best validation performance is 8.8486e-9 stopped at 103 for rhombus topology, 8.347e-9 stopped at 242 epochs, 8.8486e-9 stopped at 311 epochs for horizontal topology and 5.8012e-09 stopped at 373 epochs for square topology. The significance of the work is to increase FSR (free spectral range) by adding rings and wide FSR achieved 299.79 THz (maximum) and throughput of 0.027 W/m for rhombus topology and other performance parameters of the optical ring resonator using symmetrical rings. Such structure is small in the size and easy to fabricate. Even by the same number of rings using different topologies structure, we can vary the performance parameters as per the different applications.
A Variance Gamma model for Rugby Union matches

Published: January 2021

Abstract
Amid much recent interest we discuss a Variance Gamma model for Rugby Union matches (applications to other sports are possible). Our model emerges as a special case of the recently introduced Gamma Difference distribution though there is a rich history of applied work using the Variance Gamma distribution – particularly in finance. Restricting to this special case adds analytical tractability and computational ease. Our three-dimensional model extends classical two-dimensional Poisson models for soccer. Analytical results are obtained for match outcomes, total score and the awarding of bonus points. Model calibration is demonstrated using historical results, bookmakers’ data and tournament simulations.
User Expectations and Acceptance of Library Services at the African Union Court on Human and Peoples’ Rights
Authors: Mutisya Fidelis Katonga , Onyancha Omwoyo Bosire 
Published: January 2021

Abstract
The study sought to assess user expectations and acceptance of library services at the African Union Court on Human and Peoples’ Rights. The study, which targeted 94 library users, employed LibQUAL and SERVQUAL protocols to collect data, which were subsequently analysed using descriptive statistics. The findings revealed that users have the lowest expectations of the physical aspects of the library, namely the library as a place and of its tangibles. By contrast, users had the highest expectations in aspects associated with people and of the library collection, namely the effect of service, information control, responsiveness and reliability. The study recommends the allocation of resources in a way that ensures that the human aspects of the library remain at high levels of service quality, while shortcomings related to information control, library space and equipment should be addressed. Further, the library should invest in electronic content that users can access remotely. The findings have implications for information practice, in that studying user expectations enables libraries to understand individual and group expectations. These, in turn, will inform decision-making processes in respect of service provision, and provide justification and accountability for the resources used during such service provision.
Health and Safety Information Behaviour of Coal Miners in Pakistan
Authors: Naveed Muhammad Asif , Ali Asif 
Published: January 2021

Abstract
This research investigated health and safety information behaviour of miners working at Makarwal Coal Mines, district Mianwali, Punjab, Pakistan. A survey method using a questionnaire was deployed for data collection from 136 coal workers. Descriptive statistics were applied for data analysis using SPSS. The results indicated that the miners’ information needs were cantered mainly on protection equipment, mining diseases, healthcare services, geological hazards, accidents associated with mining and modern mining techniques. These miners relied overwhelmingly on interpersonal relationships with fellow miners and friends for safety information followed by television and radio. A good number of the survey participants also utilized internet and social media such as Facebook, WhatsApp, etc. as information source. There was little evidence of the use of audio/visual materials, seminar/workshops, associations, government agencies, and printed materials for information acquisition. Computer illiteracy, poor financial conditions, lack of time, language barriers, lack of awareness and knowledge about safety information and non-availability of relevant materials were perceived as the major constraints in acquiring safety information. The results will not only be useful for planning a need-based information infrastructure for miners but also for policymakers, NGOs and human rights organizations working for rural development and uplifting occupational health. This research contributed in the existing research on miners’ information behaviour as only a few studies appeared.
From movement into action to manner of causation: changes in argument mapping in the into-causative
Authors: Flach Susanne 
Published: January 2021

Abstract
Over the last 300 years, the into-causative (he talked his father into giving him money) increased in frequency and lexical diversity. Changes of this kind are often taken as evidence of functional expansion. From a Construction Grammar (CxG) perspective, this paper argues that what appears to be a loss of restrictions on the verbal slot results from changes in argument mapping links. As the construction provides the argument roles by mapping semantics (causer, causee, result) onto syntax (subject, object, oblique), stronger mapping links increasingly facilitated the use of verbs that are semantically and syntactically atypical for the expression of causation. Data from the Corpus of Historical American English confirm three predictions of this hypothesis with respect to shifts in (i) the semantic classes of matrix verbs, (ii) their general argument structure preferences, and (iii) voice-marking. The results provide evidence for a subtle semantic change from movement into action to manner of causation. The increase in frequency and productivity are hence explained as the consequence of the syntactic form becoming a more reliable cue for causative meaning. We discuss implications for models of language change against the background of current issues in Diachronic Construction Grammar (DCxG) pertaining to constructionalization vs. constructional change.
Don’t feel obligated, lest it be undesirable: the relationship between prohibitives and apprehensives in Papapana and beyond
Authors: Smith-Dennis Ellen 
Published: January 2021

AbstractThis paper analyses the preverbal morphemete,used in both apprehensive ‘precautioning’ sentences and in one of two prohibitive constructions in Papapana (papa1265, Austronesian, Oceanic; Papua New Guinea). I aim to establish whether there is a diachronic relationship between the two functions ofte, and in which direction, how and why semantic change may have occurred. This requires consideration of the synchronic differences between Papapana prohibitives, comparisons with apprehensive and prohibitive constructions in other Oceanic languages, and an investigation of other languages where apprehensive and prohibitive morphemes are formally similar/identical. I argue that the two functions ofteare diachronically related, but not polysemous, and that the prohibitive meaning developed from the apprehensive meaning via insubordination. This supports Pakendorf, Brigitte & Ewa Schalley’s proposed pathway of development from possibility to prohibition, via apprehension and warning. However, I argue that their pathway does not, as claimed, run counter to the proposed grammaticalisation path of deontic to epistemic modality, because prohibitives are arguably not deontic. This paper contributes to the growing body of research on apprehensives, demonstrates that the pathway from apprehension to prohibition is perhaps not as rare as Pakendorf and Schalley thought, and contributes to research on language change and modality.
Acoustic investigation of anticipatory vowel nasalization in a Caribbean and a non-Caribbean dialect of Spanish
Authors: Bongiovanni Silvina 
Published: January 2021

AbstractSpanish dialectology observes that dialects with a preference for velarized variants of /n/ (e.g. Caribbean dialects) include nasalized vocalic allophones in their inventory. Instrumental cross-dialectal comparisons of Spanish anticipatory nasalization, however, remain surprisingly rare. To this end, I compare the time-course of nasality in pre-nasal vowels in Argentine and Dominican Spanish, as well as across a number of linguistic variables described in the phonetic, sociolinguistic and historical literature. Twenty-eight speakers from Santo Domingo and twenty-six from Buenos Aires were recorded with a nasometer, an ideal instrument for data collection in the field. Measurements of nasal energy were extracted to acoustically characterize the time-course of nasality. Results indicate that Dominican speakers present more extensive anticipatory vowel nasalization than Argentine speakers. These findings are consistent with observations of allophonic nasalization (i.e. phonologized) in the Caribbean dialect under study, Dominican Spanish. Regarding the linguistic variables, stressed pre-nasal vowels showed earlier onset of nasalization, particularly among the Caribbean speakers, which further provides support for the phonological differences in vowel nasality.
