Regional Supply and Demand Fundamentals in the German Housing Price Boom
Authors: Brausewetter Lars , Thomsen Stephan L. , Trunzer Johannes 
Published: December 2023

Abstract
Over the last decade, German housing prices have increased unprecedentedly. Drawing on quality-adjusted housing price data at the district level, we show that regional fundamentals explain up to two-thirds of between-region and 77 to 87 percent of within-region variation in price growth. Price increases were driven mainly by co-movements in local demand fundamentals, notably population density and skill level. However, we further reveal systematic variation unrelated to fundamentals: overvaluation of top 7 cities, path dependency, and spatial spillovers. We infer that speculation, investor preference for liquid markets, and bounded rationality contributed substantially to the recent housing price boom in Germany.

Abstract
Studying a large number of variables measured on the same observations and organized in blocks – denoted multiblock data – is becoming standard in several domains especially in biology. To explore the relationships between all these variables – at the block- and the variable-level – several exploratory multiblock methods were proposed. However, most of them are only designed for numeric variables. In reality, some data sets contain variables of different measurement levels (i.e., numeric, nominal, ordinal). In this article, we focus on exploratory multiblock methods that handle variables at their appropriate measurement level. Multi-Block Principal Component Analysis with Optimal Scaling (MBPCA-OS) is proposed and applied to multiblock data from the CURIE-O-SA French cohort. In this study, variables are of different measurement levels and organized in four blocks. The objective is to study the immune responses according to the SARS-CoV-2 infection and vaccination statuses, the symptoms and the participant’s characteristics.
Using sentence processing speed and automaticity to predict L2 performance in the productive and receptive tasks
Authors: Zhang Xiaopeng , Yang Xiaofeng 
Published: December 2023

Abstract
We investigated the predictive capacity of second language (L2) sentence processing speed measured using reaction time (RT) and automaticity captured using the coefficient of variation (CV) on the accuracy of L2 use in receptive and productive tasks. A total of 74 Chinese English-L2 learners completed a maze task, an elicited imitation task (EIT), and a timed grammaticality judgment task (TGJT) using comparable sentences. RT and CV from the maze task were used to predict the use of L2 morphological markers in the EIT and TGJT. The findings revealed that there were no significant effects of RT and CV in the EIT. However, in the TGJT, the effect of CV was significant. These results highlight the predictive power of L2 processing automaticity in the receptive task involving L2 morphological use.

Abstract
The fifth generation is considered as the revolutionary technology around the world, but this revolution brings many challenges along with it, especially when employ the advance properties such as massive multiple-input–multiple-output (MIMO) antennae, network densification and new spectrum exploration etc. One more challenge which we consider working on is the cost effective, secure backhaul communication system. The connection of massive and large traffic cells with the core network by using backhaul demands extraordinary requirements concerning availability, latency, capacity, cost efficiency and most importantly security. In the present work, we demonstrated the security implementation in 5G backhaul network by securing RoF signal through optical chaos generated by semiconductor laser. RoF signal of 60 GHz is generated in unlicensed band and after chaos masking with chaos, signal is transmitted over optical fiber to analyze the results. Simulations are carried out by using licensed software (Optisystem version 14.0) and results are analyzed by using multiple data rates and fiber lengths. Moreover, analysis of our scheme is carried out by using RZ and NRZ formats and by varying the power of the laser.
The Functional Grammar of Dance applied to ELAN annotation: meaning beyond the naked eye
Authors: Maiorani Arianna , Liu Chun 
Published: December 2023

Abstract
The main purpose of this article is to show how Functional Grammar of Dance (FGD) can be applied to dance discourse analysis to reveal the discursive strategies that underlie choreographies and support movement-based communication. In recent years, studies in Systemic Functional Multimodal Discourse Analysis (SF-MDA) have benefited from the development of several models of analysis, and from the emergence of a new focus on the materiality of semiotic modes. The Functional Grammar of Dance is a recently developed model of analysis that draws on Systemic Functional Linguistics theory and focuses on movement-based communication starting from dance (particularly ballet as a starting point). The Functional Grammar of Dance has been adopted as a central theory in an international collaborative project funded by the AHRC (Arts and Humanities Research Council) in the UK and the DFG (Deutsche Forschungsgemeinschaft, ‘German Research Foundation’) in Germany, The Kinesemiotic Body, where it has been used with the ELAN annotation system. ELAN annotation based on the Functional Grammar of Dance was used for both live-collected data from dance rehearsals and for dance videos and revealed aspects of dance performances that are not necessarily captured by the naked eye. This paper proposes three case studies where we show that our ELAN annotation with the FGD provides an effective and very flexible interface for the grammaticalization of movement-based communication and the study of movement-based discursive strategies.
Evaluations of appropriateness through impoliteness in political discourse reframed for entertainment purposes
Authors: Chankova Mariya 
Published: December 2023

AbstractThis contribution takes a look at video-sharing platforms to highlight a popular entertainment format which consists in re-framing political discourse for the purposes of entertaining the audience and, at the same time, providing an evaluation of that discourse. Evaluations of political discourse uncover the role and importance imputed to it by those who are outside of the political system, but who are directly impacted by it, that is, the people. A sample of French-language data, collected from YouTube, is examined for the categories of evaluation which are used by the authors, which are conjectured to represent the ideas ordinary citizens have about political discourse. Reframing political discourse carries these evaluations through offensive language and humor. Teasing out the relevant parameters of evaluation can provide a basis for understanding how regular citizens gauge political discourse. Appropriateness appears to be an important evaluation criterion pertaining to the characteristics of political discourse, occurring in a particular context.
“Somewhere along your pedigree, a bitch got over the wall!” A proposal of implicitly offensive language typology
Authors: Despot Kristina Š. , Anić Ana Ostroški , Veale Tony 
Published: December 2023

AbstractThe automatic detection of implicitly offensive language is a challenge for NLP, as such language is subtle, contextual, and plausibly deniable, but it is becoming increasingly important with the wider use of large language models to generate human-quality texts. This study argues that current difficulties in detecting implicit offence are exacerbated by multiple factors: (a) inadequate definitions of implicit and explicit offense; (b) an insufficient typology of implicit offence; and (c) a dearth of detailed analysis of implicitly offensive linguistic data. In this study, based on a qualitative analysis of an implicitly offensive dataset, a new typology of implicitly offensive language is proposed along with a detailed, example-led account of the new typology, an operational definition of implicitly offensive language, and a thorough analysis of the role of figurative language and humour in each type. Our analyses identify three main issues with previous datasets and typologies used in NLP approaches: (a) conflating content and form in the annotation; (b) treating figurativeness, particularly metaphor, as the main device of implicitness, while ignoring its equally important role in the explicit offence; and (c) an over-focus on form-specific datasets (e.g. focusing only on offensive comparisons), which fails to reflect the full complexity of offensive language use.

Abstract

Trema orientalis and Trewia nudiflora are the fastest rotation trees (3–4 years’ rotation) in Bangladesh, and experimentally planted in social forestry in Gazipur district. Biorefinery is the most cited topic in research recent era in order to established circular bioeconomy. In established a biorefinery initiative, both species were fractionated into pulp, lignin and hemicellulose by formic acid (FA) treatment at atmospheric conditions. After alkaline peroxide bleaching of FA treated pulp, the yield was 47.0 % and 41.0 % with α-cellulose of 82.39 % and 81.61 %, and residual pentosan content of 9.26 % and 11.13 % for T. orientalis and T. nudiflora, respectively. The brightness of the pulps was 84.5 % and 85.0 %. Cold alkali extraction of the bleached pulp increased α-cellulose to 92.36 % and 91.29 % which was suitable for cellulose derivatives. Lignin was separated from the spent liquor by adding water. The FA lignin from hardwood replaced 20 % phenol in phenol-formaldehyde resin preparation without sacrifice of shear strength. The lignin separated FA liquor contains mainly pentose sugars, which was subsequently converted to furfural with a yield of 41.39 % and 41.72 % at 170 °C using 0.1 % H2SO4 catalyst from T. orientalis and T. nudiflora, respectively.

Published: December 2023

Abstract
In this study, we aimed to develop stable silicone rubber Pickering emulsions by employing silica nanoparticles as stabilizers in order to produce a water-borne thermal protection coating. Initially, silica nanoparticles were synthesized using the Stöber method and subsequently functionalized with γ-glycidoxypropyltrimethoxysilane (GTMS). The size and grafting efficiency of the GTMS-modified silica nanoparticles were characterized using transmission electron microscopy and thermogravimetric analysis, respectively. Furthermore, the functionalization mechanism was elucidated by monitoring the pH and Zeta potential of the silica sols. Subsequently, the silicone rubber Pickering emulsion was prepared via the emulsion inversion point method and characterized using transmission electron microscopy. The emulsification process was analyzed by measuring the conductivity of the emulsion during the phase transition. Finally, the water-borne coating was formulated by blending the emulsions with Kaolin, glass fiber, and glass microspheres. The thermal protection performance of the resulting coating was evaluated under typical test conditions, with the highest heat flow reaching 242 kW m−2 for 40 s.
Do letters matter? The influence of spelling on acoustic duration
Authors: Muschalik Julia , Kunter Gero 
Published: December 2023

Abstract
The present article describes a modified and extended replication of a corpus study by Brewer (2008. Phonetic reflexes of orthographic characteristics in lexical representation. Tucson, AZ: University of Arizona PhD thesis) which reports differences in the acoustic duration of homophonous but heterographic sounds. The original findings point to a quantity effect of spelling on acoustic duration, i.e., the more letters are used to spell a sound, the longer the sound’s duration. Such a finding would have extensive theoretical implications and necessitate more research on how exactly spelling would come to influence speech production. However, the effects found by Brewer (2008) did not consistently reach statistical significance and the analysis did not include many of the covariates which are known by now to influence segment duration, rendering the robustness of the results at least questionable. Employing a more nuanced operationalization of graphemic units and a more advanced statistical analysis, the current replication fails to find the reported effect of letter quantity. Instead, we find an effect of graphemic complexity. Speakers realize consonants that do not have a visible graphemic correlate with shorter durations: the /s/ in tux is shorter that the /s/ in fuss. The effect presumably resembles orthographic visibility effects found in perception. In addition, our results highlight the need for a more rigorous approach to replicability in linguistics.
Urbanität und Geselligkeit
Authors: Christoph Heller Jakob 
Published: December 2023

AbstractThe article explores the early Romantic theories of Friedrich Schlegel and Friedrich Schleiermacher, focusing on their re-conception of urbanity (urbanitas) as it relates to the Romantic project of a union of poetry and life. The article argues that Schlegel and Schleiermacher work to establish a newethosof interaction (indifferent to the medium) that claims validity in the literary and social fields. It reconstructs Schlegel’s theory of the formation ofethosduring theAthenäumperiod, which he applies to the writer as the paradigm of the ‚speaker‘ under new public conditions and the essay as the paradigm of negotiating uncertain knowledge. Schleiermacher’s attempt to develop a theory of social behaviour, which emerged during his time in Berlin, forms the complement to Schlegel’s poetics on the side of social practice. The essay thus shows how rhetorical knowledge is reformulated and connected to practice after the end of the discipline.

Abstract
Leandro Quidel-Catrilelbún, ME, Ruiz-Alias, SA, García-Pinillos, F, Ramirez-Campillo, R, and Pérez-Castilla, A. Acute effect of different velocity-based training protocols on 2000-m rowing ergometer performance. J Strength Cond Res 38(1): e8–e15, 2024—This study aimed to explore the acute effect of 4 velocity-based resistance training (VBT) protocols on 2000-m rowing ergometer (RE2000) time trial, as well as the behavior of the maximal neuromuscular capacities when RE2000 is performed alone or preceded by VBT protocols in the same session. Fifteen male competitive rowers (15–22 years) undertook 5 randomized protocols in separate occasions: (a) RE2000 alone (control condition); (b) VBT against 60% of 1 repetition maximum (1RM) with a velocity loss in the set of 10% followed by RE2000 (VBT60-10 + RE2000); (c) VBT against 60% 1RM with a velocity loss in the set of 30% followed by RE2000 (VBT60-30 + RE2000); (d) VBT against 80% 1RM with a velocity loss in the set of 10% followed by RE2000 (VBT80-10 + RE2000); (e) VBT against 80% 1RM with a velocity loss in the set of 30% followed by RE2000 (VBT80-30 + RE2000). The load-velocity relationship (load-axis intercept [L

0
], velocity-axis intercept [v

0
], and area under the load-velocity relationship line [A

line
]) was used to evaluate the maximal neuromuscular capacities during the prone bench pull exercise before and after each protocol. The time trial was significantly longer for VBT60-30 + RE2000 and VBT80-30 + RE2000 than for RE2000, VBT60-10 + RE2000 and VBT80-10 + RE2000 (all p < 0.001; ES = 0.10–0.15). L

0
and A

line
were significantly reduced after all protocols (p < 0.001; ES = 0.10–0.13), with A

line
reduction more accentuated for VBT60-10 + RE2000, VBT60-30 + RE2000, VBT80-30 + RE2000, and RE2000 (all p = 0.001; ES = 0.11–0.18) than for VBT80-10 + RE2000 (p = 0.065; ES = 0.05). Therefore, VBT protocols with greater velocity loss in the set (30% vs. 10%) negatively affected subsequent rowing ergometer performance, in line with impairment in A

Abstract
Brito, P, Costa, J, Figueiredo, P, and Brito, J. Simulated soccer game protocols: A systematic review on validated protocols that represent the demands of the game. J Strength Cond Res 38(1): 192–205, 2024—Several laboratory and field testing protocols have been developed attempting to simulate the activity pattern and physiological demands of soccer. In the present systematic review, we aimed to analyze and discuss the appropriateness, strengths, and limitations of soccer-specific simulated tests. A systematic review of the literature was conducted based on the PRISMA guidelines. Studies conducted in soccer, simulated soccer match tests, and validated simulation protocols performed on-the-field or on a treadmill were considered. No sex restriction was applied, and age >18 years (i.e., adults) was considered. At least 1 outcome measure (e.g., neuromuscular performance, external load, internal load, or psychometric state) of post-simulated-match test or protocol had to be reported. Within the 14 studies included, the average methodological quality of the included articles was 0.61 ± 0.09 (mean ± SD) of 1. Overall, 9 validated protocols were identified. In the protocols, only amateur, university, or semiprofessional soccer players were analyzed. Only one study evaluated female soccer players. None of the studies evaluated the effect on performance over the 2–3 days after the protocol. Accelerations and decelerations, and changes in direction typically present in a game have not been clearly described in any protocol. Future research should address this issue and validate soccer-specific protocols in women.

Abstract
Harrison, PW, James, LP, Jenkins, DG, Holmberg, PM, and Kelly, VG. Effects of repeated jump testing and diurnal changes on subsequent countermovement jump and squat jump output and force-time characteristics. J Strength Cond Res 38(1): 174–179, 2024—The aim of this brief study was to investigate the effects of repeated jump testing on performance over 2 consecutive days while considering the possibility of diurnal changes. Fourteen male subjects and 14 recreationally active female subjects completed countermovement jump (CMJ) and squat jump (SJ) testing on 5 occasions (baseline [0,800], 5 minutes [0,820], 8 hours [1,600], 24 hours [0,800], and 32 hours [1,600]) over 32 hours. An additional rested baseline test was conducted on a separate day in the afternoon (1,600) to compare jump performance between morning and afternoon baseline values. Excluding small decreases in CMJ height at 24 hours (p = 0.292, Cliff’s delta = −0.225) in male subjects and similar decreases in CMJ height at 5 minutes (p = 0.034, Cliff’s delta = −0.245) in addition to SJ height:contraction time at 32 hours (p = 0.126, Cliff’s delta = 0.153) in female subjects, findings generally showed no changes in jump performance over multiple assessments. Squat jump metrics may have showed small improvements between morning and afternoon baseline values in male subjects (SJ height:contraction time [p = 0.030, Cliff’s delta = 0.225]) and female subjects (SJ height [p = 0.013, Cliff’s delta = 0.173] and SJ height:contraction time [p = 0.091, Cliff’s delta = 0.163)]. As jump performance was largely unaffected by repeated jump testing, the present findings support the use of monitoring practices and research designs that require multiple jump assessments within acute periods (∼32 hours).
Alternative salt frost scaling test procedure for exposure class XF2
Authors: Müller Matthias , Seidel Maik , Ludwig Horst-Michael , Müller Christoph 
Published: December 2023

AbstractConcrete structures in cold and moderate climates are often exposed to a combined salt frost attack, which can cause scaling damage. Consequently, numerous test procedures were developed to determine the resistance of concrete compositions against this kind of attack. These tests mimic a severe attack with high levels of saturation, which is typical for horizontal concrete elements or structures, such as concrete pavements. Very few approaches exist for testing the salt frost scaling resistance of concretes for vertical concrete elements like bridge columns, which are subjected to only moderate levels of saturation during salt frost attack (exposure class XF2). As such elements usually didn’t show notable scaling damage in practice, this hasn’t posed a problem until recently. However, the increasing use of low carbon cements with high clinker substitution rates might increase the vulnerability against salt frost exposure for such concrete elements to some extent. To ensure adequate durability it is desirable to determine the performance of the concrete in an actual test procedure instead of relying on descriptive criteria alone. Thus, a less severe test method was developed, which is based on the CDF test. It was shown that the modified test procedure can distinguish correctly between different concrete qualities. Furthermore, the applicability of an acceptance criterion for the method was investigated.
A Quantitative Approach to Challenges Facing Online and Physical Classes in Social Studies Learning Higher Education
Authors: Omolaf BABALOLA Ebenezer , Ize OLUDARE Precious 
Published: December 2023

The aim of this research is to investigate the challenges faced by online and physical classes in social studies learning in higher education. This condition causes differences in online or physical face-to-face classes. Descriptive research of the survey type was employed to achieve the purpose of this study. Students in five randomly selected faculties in University of Ilorin, Nigeria made up the study target population. In order to choose sample from each of the selected faculties, proportionate sampling procedure was used. The actual sample size for the study was 200 Undergraduates, who were chosen using random selection techniques. Descriptive statistics of mean score were used to analyse the information obtained from the respondents. The findings of this study shows that students faced challenges while learning in both online and physical classrooms. It was concluded that despite the underlying similarities between online and physical classroom, the two modalities are very different from one another. Online teaching is typically student-centered which necessitates active learning, in contrast to traditional classroom instruction, which has been known to be teachers-centered and call for passive learning. It was a challenge for teachers to move from face to face in class mode to virtual learning, changing their teaching methodologies, and managing their time. And it was also a challenge to develop content which did not only covers the curriculum but also engage the learners.
