Acquisition of attributive adjectives and noun adjuncts by L3 learners of French and German: further evidence for the typological primacy model (TPM)
Authors: Jamali Maryam , Jabbari Ali Akbar , Razmi Mohammad Hasan 
Published: August 2021

Abstract
This investigation explored the impact of prior acquired languages in the acquisition of third language (L3) at initial stages. The required data were gathered via two groups of L3 learners: 27 learners of L3 French and 26 learners of L3 German during a grammaticality judgement task (GJT) and an element rearrangement task (ERT) to test the placement of noun adjuncts and attributive adjectives. Both groups had acquired Persian as the first language and English as the second language. The participants were assigned to two L2 proficiency level groups (intermediate and advanced). The findings revealed that L3 German participants outperformed L3 French learners in the attributive adjective placement in both tasks as well as the noun adjunct in the GJT task. The L3 groups showed similar levels of performance in the ERT noun adjunct task. Additionally, the effect of L2 level of proficiency was not significant. The results also indicated that the typological similarity of L2 English to German rather than French rendered a facilitative effect on task performance in the L3 German group and a non-facilitative effect in the L3 French group. This study provides evidence for the Typological Primacy Model (TPM) of L3 acquisition suggesting that L3 learners are influenced by the typological similarities of the previous languages they have already acquired.

Authors: Ng Jeremy Y. , Anagal Mrinal , Bhowmik Trisha 
Published: August 2021

Abstract

Objectives
The purpose of this systematic review of qualitative studies is to explore patients’ perceived effectiveness of utilizing complementary and alternative medicine (CAM) for the treatment and/or management of low back pain (LBP).

Methods
MEDLINE, EMBASE, AMED, and CINAHL were systematically searched from database inception until May 2020. Eligible articles included qualitative data about LBP patients’ perceptions of using CAM.

Results
Of 1,567 items, 1,542 items were excluded; the remaining 25 articles were included in this review. Three themes emerged as follows: physical benefits; mental health benefits; and negative or no perceived effectiveness of CAM on patients with LBP.

Conclusions
This study explores perceptions of CAM effectiveness among patients with LBP. These findings provide valuable information to CAM and non-CAM practitioners regarding the importance of individualized patient care based on their preferences, values, needs, and perspectives. Further exploration could include practitioners’ perceptions of CAM and their impact on the patient-practitioner relationship.
Some Thoughts Evoked by Peter Lor, Bradley Wiles, and Johannes Britz, “Re-thinking Information Ethics: Truth, Conspiracy Theories, and Librarians in the COVID-19 Era,” in LIBRI, March 2021
Authors: Froehlich Thomas

Abstract
The paper offers some thoughts prompted by the research paper published by Peter Lor, Bradley Wiles, and Johannes Britz, “Re-Thinking Information Ethics: Truth, Conspiracy Theories, and Librarians in the COVID-19 Era,” in LIBRI, March 2021. It highlights two significant contributions, an analysis of the misinformation in the COVID-19 pandemic and the notion of alethic rights, the right of truth of patrons based on the work of D’Agostini. This reflection then situates the COVID-19 misinformation campaign within the broader disinformation ecology within which it exists. While it agrees that alethic rights are an important ethical framework, it wonders whether it practically advances work beyond that libraries and librarians are already doing, e.g., in collection decisions, approaches to reference questions, or library programming. It looks at the debate between John Swan and Noel Peattie on the inclusion of books representing outright lies in the collection (e.g., Holocaust denial). It then contrasts a right to information and authorities propagating and validating that information with a right to misinformation and authorities for propagating and validating that misinformation that exists within disinformation ecologies. The problem of truth, its authorities and its context appears to be more complicated than an appeal to alethic truths: for example, liberals and conservatives differ on the meaning of a rational consensus on contentious political matters, such as climate change. Given the dire consequences of misinformation on democracies and public health, an appeal to professional neutrality is woefully inadequate. There must be proactive resistance, if not outright repudiation.

Influences of poling temperature and elongation ratio on PVDF-HFP piezoelectric films
Authors: Jin Zhaonan , Lei Dan , Wang Yang , Wu Liangke , Hu Ning 
Published: August 2021

Abstract
Poly(vinylidene fluoride) (PVDF) and its copolymers exhibit excellent piezoelectric properties and are potential materials for high efficiency energy harvesting devices. In this study, poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) films are prepared by the solution casting method. The prepared film is then subjected to mechanical stretching and poling process. By adjusting the temperature of the poling process and the elongation ratio of the mechanical stretching process, the relative content of β-phase F(β) increases significantly, leading to high piezoelectric performance. The maximum output voltage of the PVDF-HFP films poled at 40°C reaches 3.67 V, 71% higher than that of the films poled at room temperature. Fourier transform infrared spectroscopy analysis (FTIR), XRD (X-ray diffraction), and differential scanning calorimetry are used to investigate the influences of mechanical stretching and poling process on the crystal structure to discover the enhancement mechanism. This work provides a straightforward and low-cost route to prepare high piezoelectric PVDF-HFP-based materials.
Exploring the Craft of Exilic Thinking/Becoming
Authors: des Bouvrie Nicole 
Published: August 2021

Abstract
Being-at-home in a particular, determined, world is dangerous for thinking. For thinking to be thinking/becoming, one should not get too comfortable. For thinking is to not arrive back home, in the same place one begins. But how to escape the world that has created who you are, gave you purpose and a past? How to make sure the future is not a repetition of the Same? How to break away from something that you need? In this article, my aim is not to give one more solution to this fundamental problem that is in essence an ethical problem. For providing a refuge, a new theory, a new methodology, would be providing a new island for those who realise that a flood is endangering their own island. My aim is to exercise the craft of exilic thinking as a way to deal with the contradiction already pointed out by Heraclitus and Parmenides – “We both step and do not step in the same rivers. We are and are not.” Exilic thinking as a craft of fragilising the self establishes a matrixial borderspace through which the impossible becomes possible.
Competition and Schedule Padding in the US Airline Industry
Authors: Yimga Jules 
Published: August 2021

Abstract
Disclosure programs can help consumers with limited information about product quality make better purchase decisions. A quality disclosure mandate such as the On-Time Disclosure Rule in the U.S. that requires airlines to provide information on the quality of their products can be beneficial, but can also be counterproductive if it encourages airlines to act deceptively by “gaming” the system. If airlines care about public perceptions of their on-time record, they have an incentive to improve their on-time performance ranking by resorting to unscrupulous means such as padding their schedules beyond normal time required to absorb scheduling stochastic fluctuations. This study investigates the impact of competition on airline schedule padding. We construct a measure for schedule padding under different optimal flight time choices. Using different measures of market structure, we find that more competitive (concentrated) markets are subject to less (more) schedule padding.
Steifigkeitsmessungen von AFM-Cantilevern
Authors: Dannberg Oliver , Fröhlich Thomas 
Published: August 2021

Zusammenfassung
Zur rückführbaren Kraftmessung mit AFM-Cantilevern ist aufgrund von Fertigungstoleranzen eine individuelle Kalibrierung jedes einzelnen Cantilevers notwendig. An der TU-Ilmenau wurde ein Prüfstand entwickelt, welcher die Steifigkeit nach einem statisch experimentellen Verfahren bestimmt. Dabei wird der Cantilever um einen definierten Weg ausgelenkt und die dazu notwendige Kraft gemessen. Die Wegmessung erfolgt durch ein kommerzielles Differenzinterferometer und die Kraftmessung mithilfe einer neu entwickelten Wägezelle. In diesem Artikel wird die Funktion des Prüfstandes am Beispiel einer Kalibrierung beschrieben und ein Messunsicherheitsbudget aufgestellt. Die relative Messunsicherheit beträgt ca. 1,5% bei einer maximalen Kalibrierkraft von <100 nN. Eine anschließende Untersuchung des Cantilevers ergab keine nachweisbaren Schäden an dessen Spitze.
Tuning capacitance wire-mesh sensor gains for measurement of conductive fluids
Authors: Dias Felipe d. A. , Wiedemann Philipp , da Silva Marco J. , Schleicher Eckhard , Hampel Uwe 
Published: August 2021

Abstract
In this paper, the front-end circuit of a capacitance wire-mesh sensor (WMS) is analyzed in detail and a new methodology to tune its feedback gains is reported. This allows, for the first time, a capacitance WMS to be able to provide linear measurements of multiphase fluids with electrical conductivity greater than 100 𝜇S/cm, which is particularly important for tap water, where the conductivity is typically in between 100 S/cm and 500 𝜇S/cm. Experimental and numerical results show that the selected gains using the proposed methodology contribute to suppress cross-talk and energy losses, which in turn, reduces considerably the deviation of the conductivity measurement and the estimation of derived flow parameters, such as local and average phase fraction.
Gaussian Process Regression Based Robust Optimization with Observer Uncertainty for Reconfigurable Self-x Sensory Electronics for Industry 4.0
Authors: Zaman Qummar , Alraho Senan , König Andreas 
Published: August 2021

Abstract
This paper presents a robust optimization technique for the reconfigurable measurement of sensory electronics for industry 4.0 to obtain a robust solution even in the presence of observer uncertainty using a cost-effective performance measurement method. The extrinsic evaluation of the proposed methodology is performed on an indirect current-feedback instrumentation amplifier (CFIA), which is a fundamental part of sensory systems. To reduce the CFIA device performance evaluation set-up cost, a low-cost test stimulus is applied to the circuit under test, and the output response of the circuit is examined to correlate with the device’s performance parameters. Due to the complexity of the smart sensory electronics search space, the meta-heuristic optimization algorithm is being selected as an optimizer. For objective space or observer uncertainty, the Gaussian process regression from the Bayesian statistical regression process is used to estimate the uncertainty level efficiently. Six different classical metrics have been used to evaluate the regression model accuracy. The highest achieved average expected error metrics value is 0.313, and the minimum value of correlation performance metrics is 0.908. The device is implemented using 0.35 μm austriamicrosystems technology.

ABSTRACT
Kicking is an essential skill for combat athletes and military personnel. Therefore, the aim of this article is to present evidence-based training principles to achieve beneficial changes in technique and performance through functional training. The profile of subelite and elite kickers is presented and is used as a foundation for exercise prescription in both populations. The article emphasizes the importance of combining both functional training with a core emphasis and traditional general strength preparation to improve all aspects of front push kick performance. Example training programs for both subelite and elite kickers are presented that are based on a block periodization approach.
Injury Prevention in Tennis Players, Linking the Kinetic Chain Approach With Myofascial Lines: A Narrative Review With Practical Implications
Authors: Ličen Teja , Kalc Miloš , Vogrin Matjaž , Bojnec Vida 
Published: August 2021

ABSTRACT
Myofascial chains refer to the soft tissue elastic connections that envelop the muscles throughout the entire body. Evidence points to the ability of myofascial chains to transfer the force developed in one muscle-tendon-joint unit to other proximal or distal musculotendinous units. Tennis is a sport demanding repetitive high-power unilateral movements, which predisposes the players to various musculoskeletal adaptations that may interrupt their optimal biomechanics and result in possible injuries. Myofascial training addresses the player's biomechanics of movement, muscle coordination, and muscle force production. This narrative review with practical examples links the well-known kinetic chain approach with myofascial training aiming to optimize rehabilitative and prevention programs, directed to primarily decrease injury incidence and beneficially impact biomechanical patterns of movement.

Published: August 2021

AbstractPsychostimulants such as amphetamine (AMPH) target dopamine (DA) neuron synapses to engender drug-induced plasticity. While DA neurons modulate the activity of striatal (Str) cholinergic interneurons (ChIs) with regional heterogeneity, how AMPH affects ChI activity has not been elucidated. Here, we applied quantitative fluorescence imaging approaches to map the dose-dependent effects of a single dose of AMPH on ChI activity at 2.5 and 24 h after injection across the mouse Str using the activity-dependent marker phosphorylated ribosomal protein S6 (p-rpS6240/244). AMPH did not affect the distribution or morphology of ChIs in any Str subregion. While AMPH at either dose had no effect on ChI activity after 2.5 h, ChI activity was dose dependently reduced after 24 h specifically in the ventral Str/nucleus accumbens (NAc), a critical site of psychostimulant action. AMPH at either dose did not affect the spontaneous firing of ChIs. Altogether this work demonstrates that a single dose of AMPH has delayed regionally heterogeneous effects on ChI activity, which most likely involves extra-Str synaptic input.

We study the structural and electronic properties of YxIn1-xN in the concentrations x = 0, ¼, ½, ¾, and 1 in the B1, B2, B3 and B4 structures using density functional theory (DFT). The calculations show that for Y0.75In0.25N, the B1 structure is the most favorable energetically. It was determined that between in the supercell, the most energetically stable structure is the B3 phase. Additionally, between concentrations x of Yttrium, the compound is most energetically favorable in the B4 phase. Technical data that are in agreement were recently reported by other authors. Finally, between 0.12 , the most stable phase is B1. Additionally, there is no phase transition between the four structures considered. The DOS and band structure show that Y0.75In0.25N in the B1 and B3 phases exhibits semiconductor behavior, with a direct gap of ~0.6 eV and ~0.7 eV, respectively while Y0.75In0.25N in the B4 phase has an indirect one of ~0.8 eV.

Abstract
The aim of this study was to investigate the effect of Lactobacillus reuteri E81 (LRE) probiotic supplementation on heat stress responses in chukar partridges (Alectoris chukar). The birds were divided into two groups, one of which was exposed to heat stress (HS). Within each group, four subgroups, each including 64 birds, were created for the three treatment doses (200, 400 or 600 mg/kg) of LRE and the control. The experiment was started with day-old birds, kept at a temperature of 25 °C or 37 °C. After a 7-day adjustment period, the LRE supplementation lasted for 35 days. The levels of different adipokines, including visfatin (VF), adiponectin (ADP), chemerin (CHEM), as well as the concentration of plasma citrulline (CIT) and the levels of thyroid hormones (T3 and T4) and thyroid-stimulating hormone (TSH) in the blood were measured at 21 and 42 days of age. A significant correlation (P < 0.01) was found between LRE supplementation and the decrease in serum VF, ADP, CIT, T3 and T4 levels in partridges exposed to HS. On the other hand, no significant relationship was found between LRE supplementation and the serum CHEM and TSH levels (P > 0.05). We concluded that the addition of 600 mg/kg LRE is beneficial in preventing intestinal damage and inflammation provoked by HS.

Published: August 2021

Background and Study Aim. The aim of the research is to investigate the efficiency of designed complexes of training exercises aimed to improve the coordination abilities of qualified athletes in fencing.
Material and Methods. 22 qualified athletes specializing in fencing aged from 15 to 18 took part in the research. The study design included the sequential pedagogical experiment that was realized through the several stages. At the first stage, the preliminary testing of the athletes’ coordination abilities (n=22) was conducted. During the preliminary testing the following tests were applied: jumps to the line; shuttle run (4x9 m.); T-test, straight touch from en-garde position to the target of 10 cm in diameter from close range (10 attempts); straight lunge attack from en-garde position to the target of 10 cm (10 attempts). At the second stage of the pedagogical experiment two complexes of exercises aimed at developing the coordination abilities of the athletes were applied for 3 months. The experimental complexes of exercises were used twice a week. At the third stage, the efficiency of experimental complexes aimed at the developing of coordination abilities of qualified athletes in fencing was checked through a control testing. The Statistica 10 software created by the StatSoft Company was used for statistical processing of data.
Results. It was established that during the process of coordination abilities development, the greatest attention should be given to the athletes’ ability to control timing, spatial and physical parameters of moves and moves consistency. To improve the process of developing the coordination abilities of the qualified athletes in fencing two complexes of training exercises were developed. The results of the pedagogical experiment confirmed the statistical differences in the levels of the athletes’ coordination abilities manifestation before and after using experimental training complexes (p<0.05).
Conclusions. It has been shown that specially developed training complexes could be used during the training process in order to develop and increase the level of coordination abilities of qualified athletes in fencing. The analysis of experts’ opinion showed that the development of coordination abilities in fencing should be oriented towards the development of athletes’ ability to control timing, spatial and physical parameters of movements.
