New approach towards predicting local f0 movements using Linear Least Squares by SVD
Authors: Peter Naoki , Leemann Adrian
Published: July 2022

Gegenstand der vorliegenden Arbeit ist die Anwendung von Linear Least Squares by SVD auf die Analyse der lokalen Akzentkonturen der Grundfrequenz (f0) des Walliserdeutschen. Ein zentraler Vorteil dieser Methode liegt darin, dass die Wichtigkeit der verschiedenen Varianten von kategorischen Variablen separat berechnet wird und zudem auch numerische Variablen verwendet werden können. Ausgehend von den walliserdeutschen Sprachdaten von Leemann (2012) im Rahmen des Fujisaki-Modell Ansatzes konnten Parameter errechnet werden, die 80% der Positionen von lokalen Akzenten in einem Testdatensatz korrekt voraussagen können (Peter, 2011). Dies ist insofern erstaunlich, als die Intonationsstrukturen des Walliserdeutschen landläufig als "unverständlich" (Ris, 1992), "exotisch" (Werlen und Matter, 2004) oder "hochgradig variabel" (Leemann, 2012) gelten.
Rhythmische Variabilität bei synchronem Sprechen und ihre Bedeutung für die forensische Sprecheridentifizierung
Authors: Friedrichs Daniel , Dellwo Volker
Published: July 2022

Humans are able to speak in synchrony with each other. The present study investigated whether four temporal correlates of speech rhythm (%V, nPVI-C, nPVI-V, nPVI-CV) adapt when speaking in synchrony with a recording. The experimental setting consisted of three conditions: Eight participants read three sentences out loud (read), four of them were asked to speak in synchrony (sync) with the same sentences recorded by the four others (target). Correlation analysis was carried out between the rhythmic measurements of the sync condition and the two others (read/target). Results revealed that there are typically strong significant correlations between speech rhythm of the read and synchronous speech. The impact on speaker identification, in particular under forensic circumstances, is discussed.
Audiovisuelle Sprechererkennung durch linguistisch naive Personen

Published: July 2022

Human speech perception is not only based on acoustic speech signals but also on visual cues like lip or jaw movements. Based on this assumption we used a between-subject design to test listeners’ speaker identification ability in a voice line-up after they were familiarized with a speaker under either of the following condition: (a) visual and degraded acoustic information, (b) degraded acoustic information only, and (c) visual information only. The results from this experiment indicate that listeners are able to perform the identification task to a considerable degree under all three experimental conditions. We conclude that listeners’ identification ability of speakers based on degraded acoustic material is about as good as their identification ability based on visual speech cues. The combination of acoustic and visual cues does not enhance listeners’ performance.
fonctionnement de l'hyperbole dans l'humour des chroniques du Monde
Authors: Vivero García María Dolores
Published: July 2022

Die Analyse des Humors, welcher sich in den Chroniken der Zeitung Le Monde finden lässt, legt nahe, die Übertreibung des Positiven von derjenigen des Negativen zu unterscheiden. Die erste Übertreibung entspricht der ironischen Hyperbel, die zweite der karikaturistischen Hyperbel, die das axiologisch Negative verzerrt. Ausserdem werden wir ungewöhnliche, die Hyperbel verstärkende Gleichsetzungen und Vergleiche untersuchen, für die der Sprecher nicht ernsthaft geradesteht. Der von der karikaturistischen Übertreibung geprägte Humor, dessen Effekte durch die Interpretation der amüsanten Hyperbeln gedämpft werden, verspottet manchmal nur die aussergewöhnlichen Eigenschaften von Sachverhalten. In bestimmten Kontexten, B. in journalistischen Chroniken, kann diese Art von Humor jedoch zu einer Abwertung dessen führen, was üblicherweise geschätzt wird.
genre des noms inanimés utilisés comme noms communs de personnes
Authors: Elmiger Daniel
Published: July 2022

This article deals with denominations used to refer to human persons (personal nouns). In addition to the designations traditionally used for humans, a number of other nouns (also referring to inanimate referents) can, contextually or usually, be used as personal nouns. These items (such as 'tête', "head") generally have a grammatical gender that is maintained in the metonymic use, whether the word refers to a man or a woman. However, this gender is not always stable: In the past, a number of nouns designating a human by metonymy have become full personal nouns that can be used with both genders, like the majority of personal nouns. A similar evolution can be assumed for a number of other types of figurative use, for which attestations and a theoretical framework are provided to explain this movement.
Collaborer avec l'entourage pour mieux implémenter une CAA

Published: July 2022

Communication partner instruction of indi viduals using augmentative and alternative communication (AAC) is a huge challenge for speech and language therapists. The purpose of this article was to identify the active ingredients of AAC communication partner interventions based on available data. In a first step, we identified targets and implementation strategies that have been sh own as effective in parent implemented communication interventions with young child ren. In a second step, these data were supplemented by studies on the training of communication partners in the context of the use of AAC. Taken together, these studies point out that the most effective targets to improve the interaction style of partners consist in training their responsiveness and use of language models. Pragmatic outcomes (e.g., tu rn-taking), the access to spontaneous communication and a support for understanding have to be added for AAC interventions. To achieve this, the instructional methods employed with communication partners should include various combinations of implementation modalities (e.g., information sharing, modeling, guided practice, verbal rehearsal and feedback). Verbal rehearsal was shown to have a key role for the efficacy of the implementation. Finally, the communication partner's proficiency level with the AAC device should also be considered.

Research has shown that 90% of children with complex communication needs (CCN) reach adulthood without functional skills in literacy. The intervention program presented in this article to help children with CCN to acquire these skills and common vocabulary through AAC. In this program, children books are read, repeatedly, to young children with CCN by using different modes of communication (wri tten words that are read aloud, gestures, pictograms and an application with speech output on a tablet). Each reading session was designed to allow specific and progressive learning processes. The child can use the code(s) corresponding to his/her needs and abilities, which promotes interactions based on the book.

Authors: Lopez-Albarran Pablo , Pizzi Antonio , Herrera-Bucio Rafael , Sánchez-Badillo Joel , Gallo Marco , Hernández-Esparza Raymundo , Garza Jorge
Published: July 2022

Oligolignols composition in an efficient adhesive formulation, were studied to identify the interactions that drive their contact and Young’s modulus with a cellulose surface. Oligolignols’ molecular structures were modeled to elucidate the formation of complexes over a crystallite model of cellulose Iβ. Hybrid quantum mechanics/molecular mechanics (QM/MM) computations were carried out for the coupled molecular geometries of the oligolignol-cellulose complexes. The achieved conformations were used to obtain wavefunctions at the interaction region to develop a non-covalent interactions (NCI) study from the atoms in molecules (AIM) theory, implemented through graphics processing units (GPUs) calculations. It was found that non-covalent interactions command the forces associated to adhesive-cellulose contacts, mainly by C-H···O hydrogen bonds, driving the long-range interactions that promote the adhesion of oligolignols on cellulose Iβ. Furthermore, the results of interaction energy suggest that the strongest Young’s modulus is obtained from oligolignols with two and three monolignols on our cellulose Iβ crystallite model. We propose a QM/MM study considering NCI and AIM analysis, as a significant new framework to design adhesive formulations. Besides, the present work can contribute to the description of interactions between lignin components and cellulose.

Published: July 2022

Four-membered nitrogen-containing heterocycles are highly desirable functional groups with synthetic and biological applications. Unsaturated 4-membered N-heterocycles, 1- and 2-azetines, are historically underexplored, but have recently been gaining increased interest due to the development of new synthetic methods to access these compounds, and to their potential as reactive intermediates. This review covers new strategies for the synthesis of 1- and 2-azetines with a particular focus on advances made since 2018. Additionally, the use of these compounds as intermediates to access other heterocycles (3- to 6-membered) and complex products is comprehensively discussed.
A Systematic Analysis and Prediction of the Target Space of Bioactive Food Compounds: Filling the Chemobiological Gaps
Authors: Sánchez-Ruiz Andrés , Colmenarejo Gonzalo
Published: July 2022

Food compounds and their molecular interactions are crucial for health and provide new chemotypes and targets for drug and nutraceutic design. Here we retrieve and analyze the complete set of published interactions of food compounds with human proteins, using the FooDB as compound set and ChEMBL as source of interactions. The data is analyzed in terms of 19 target classes and 19 compound classes, showing a small fraction of target assignment of the compounds (1.6%) and unraveling multiple gaps in the chemobiological space for these molecules. By using well established cheminformatic approaches (Similarity Ensemble Approach (SEA) combined with the maximum Tanimoto Coefficient to the nearest bioactive, “SEA + TC”) we achieve a much enhanced target assignment (64.2%), filling many of the gaps with target hypothesis for fast focused testing. By publishing these datasets and analyses we expect to provide a set of resources to speed up the full clarification of the chemobiological space of food compounds, opening new opportunities for drug and nutraceutic design.

Published: July 2022

Cells in living systems are stimulated to produce diverse biological responses, which are regulated by complex chemical reaction networks (CRNs). Artificial CRNs, primarily relying on sophisticated multi-enzyme or nucleic acids architectures as basic units, provide a powerful abstraction to formally represent marvelous biochemical processes. From a perspective of large-scale industrial applications, it is highly envisioned to substitute natural molecules to develop CRNs with similar behaviors but remains a grand challenge. Herein, we report single atom Co-N-doped carbon nanotubes (Co-N-CNTs) as the basic unit for CRNs. Thanks to multiple nanozymatic reactions of Co-N-CNTs, several essential biological regulation functionalities were successfully integrated into a single programmable network, including cascade reaction, negative feedback, and positive feedforward. By incorporating the proposed nanozymatic network into microfluidic flow reactors as a cell mimic, selective recognition of small reductive biomolecules was further achieved under the bypass mode. This work would open a new avenue for artificial CRNs construction and extend biological applications of lifelike materials.

Women in the Uyghur Advocacy Movement in Canada: The Making of a Political “Activist"
Authors: Palmer Susan J. , Mahmut Dilmurat , Udun Abdulmuqtedir
Published: July 2022

This study analyzes the life stories of three female Uyghur political activists. Born and raised in East Turkestan/Xinjiang, all three chose to emigrate to the West. Today they live in Canada, advocating for the rights of Turkic peoples in their “Homeland” and raising public awareness of the CCP’s campaign against the Uyghurs, a campaign which is currently recognized as genocidal by seven countries as well as a number of human rights organizations. This study adopts a narrative analysis of these life stories, which were collected as a form of oral history. The narratives focus on the experiences of ethnic Uyghurs living, studying, and working in China in the 1980s–2000s during the ongoing crackdowns and “strike hard” campaigns in East Turkestan/Xinjiang. Through the techniques of narrative analysis, we investigate and analyze the tensions, turning points, and motivations which led to their personal transformations and decision to become publicly involved in creating social and political change for their community. While the political statements of Rukiye Turdush, Arzu Gul, and Raziya Mahmut have been widely circulated in Canadian government and media reports, this study focuses on their personal lives and the troubling, traumatic events in their youth which triggered their choice to leave China. We ultimately argue that a narrative analysis of their stories helps us perceive these narratives as a continuation of their activism.

Konflik Berkepanjangan Ethiopia: Sebuah Penghampiran Mediasi Ethiopia-Tigray
Authors: Pragilaksono Bimo
Published: July 2022

On November, 4th 2020, the Tigrayan Area became one of the deadly conflict hotspots in the midst of the global pandemic Covid-19. The conflicts are rooted since the Ethiopian People’s Democratic Front (EPRDF) becoming the governing party 30 years ago that reigned by corrupt, dirty, discriminate governance. EPRDF was in coalition with four parties: Amhara Democratic Party (ADP); The Oromo Democratic Party (ODP); Southern Ethiopian People’s Democratic Party Movement (SEPDPM); and Tigrayan People’s Liberation Front (TPLF). Among the four parties, only the TPLF has been promoted and acquired privileges by the EPRDF. These privileges provide TPLF an influence, an important political position, and a military sector, which creates other parties feel excluded. Political friction, sexual violence, and even the issue of ethnic cleansing of Tigrayans underlie the crisis. Since Abiy Ahmed from ODP become a new PM of Ethiopia, it is strongly indicated that his position indirectly supports reprisal against TPLF. The involvement of Eritrea in this conflict, expanding the spectrum of crisis. Deadlock on the solution and the unilateral claims of the Abiy’s successful (offensive) settlement against TPLF, agonizing the situation of the Tigrayan people. Therefore, in this essay, the author will explain how the characteristics of the current conflict situation, the ripeness of conflict, methods of resolution of mediation, and possible solution to construct a stable situation in the Tigray Conflict.

Дослідження маневреності триланкового причіпного автобусного поїзда
Authors: Сахно Володимир Прохорович , Поляков Віктор Михайлович , Шарай Світлана Михайлівна , Мурований Ігор Сергійович
Published: July 2022

Метробус, або нова система автобусного руху «Швидкісний автобусний транспорт» (Bus rapid transport, BRT), є результатом розвитку мережі автобусного суспільного транспорту. Порівняно з метро цей проєкт має явні переваги: менша вартість створення мережі, менша вартість рухомого складу, мобільність та ін. Поряд із незаперечними перевагами триланкових зчленованих автобусів і тролейбусів їм притаманні і недоліки – гірші маневреність і стійкість руху порівняно з дволанковими. Крім того, ефективність експлуатації таких машин тісно пов’язана з пасажиропотоком, який протягом дня може змінюватися в рази. Тому перспективним може стати автопоїзд у складі двох (або трьох) автобусів або тролейбусів, що працюють у зчіпці, пасажиромісткість яких аналогічна зчленованим автобусам і тролейбусам. У години пік працює автобусний поїзд, а у міжпіковий період – кожний автобус окремо (можлива стоянка одного автобуса на виділеному майданчику).  Для такого автобусного поїзда, що складається із трьох однотипних автобусів (на прикладі МАЗ-206), визначені показники маневреності, зокрема показано, що при неграничному повороті поворот усіх автобусів здійснюється на першій стадії послідовно, причому третій автобус забігає більш інтенсивно у внутрішню сторону повороту, збільшуючи другий кут складання, порівняно з першим, і четвертий, порівняно з третім. Під час усталеного колового руху автопоїзд у складі трьох автобусів МАЗ-206 забезпечує нормовані значення габаритної смуги руху. Позитивним при цьому також є те, що для автобусів зі стандартними системами керування їх відносна кутова швидкість суттєво зменшується і поліпшується стійкість автопоїзда під час виконання повороту.

Published: July 2022

У роботі розглянуто особливості поширення магнітного поля в прямокутній пластині з анізотропного за коефіцієнтом магнітної проникності  матеріалу. Встановлено залежності поздовжньої та поперечної складових магнітного поля від геометричних розмірів пластини та кута нахилу вибраних головних кристолаграфічних осей. Вперше показано можливість концентрації величини напруженості  магнітного поля і проведено відповідну оптимізацію її величини. Представлено моделі анізотропного магнітного концентратора, а також запропоновано метод його створення на основі штучних анізотропних, як класичних, так і метамагнітних, матеріалів. Застосування запропонованого методу веде до появи нових енергетичних перетворювачів автономної екологічночистої енергії, що не потребує класичних енергоносіїв. Метод концентрації магнітного поля з використанням штучних анізотропних класичних матеріалів покращує показники електромагнітних і магнітоелектричних вимірювальних систем, проте не зовсім задовольняє вимоги до новітніх технологічних пристроїв. Подальше підвищення коефіцієнта концентрації магнітного поля досягається при використанні штучних анізотропних метамагнітних матеріалів, що характеризуються від’ємним значенням магнітної проникності у одному із вибраних головних кристолаграфічних напрямків. Запропоновані методи концентрації магнітного поля знайдуть використання у електротехніці, радіотехніці, метрології та інших пов’язаних із ними галузей.

KAJIAN PERJALANAN ISRA’ MI’RAJ NABI MUHAMMAD SAW DALAM PERSPEKTIF FISIKA
Authors: Juriyah Juriyah , Suprapto Nadi
Published: July 2022

Tujuan penelitian ini adalah menganalisis jalur perjalanan Isra’ dan Mi’raj Nabi Muhammad serta perspektifnya di bidang fisika. Metode penelitian yang digunakan adalah strategi penelitian kualitatif dengan data primer dan data sekunder sebagai pendukungnya. Dalam menyelesaikan penelitian ini, dibutuhkan data hasil wawancara serta karya ilmiah yang sesuai dengan topik penelitian ini, yang mana diperoleh data yang bersifat teoritis. Untuk memperoleh data yang akurat, yang harus dilakukan adalah mempelajari topik Isra’ Mi’raj dalam perspektif fisika melalui data yang telah dikumpulkan sebelumnya. Dalam hal ini, peneliti memperoleh pengetahuan baru yang kemudian dapat dikaji lebih dalam. Setelah itu, melakukan analisis data yang telah dipelajari dan dikumpulkan sebelumnya dan mengandalkan konsep dan teori yang ada untuk kemudian memperoleh pembahasan dalam penelitian. Melalui penelitian ini, dapat diketahui bahwa Teori Nol Kelvin dan Prinsip Ketidakpastian Heisenberg sejauh ini sesuai untuk menjelaskan peristiwa Isra’ Mi’raj. Sedangkan Teori Relativitas Einstein dianggap belum cukup mampu menjelaskan peristiwa Isra’ Mi’raj, karena terdapat penjelasan yang kurang sesuai. Seperti, ketika tubuh Nabi Muhammad melaju dengan kecepatan cahaya, maka tubuhnya akan meledak. Dengan demikian, Teori Relativitas Einstein bukan teori yang tepat untuk menjelaskan fenomena Isra’ Mi’raj.

 

Kata kunci: Nabi Muhammad, prinsip ketidakpastian Heisenberg, isra’, mi’raj, dan Teori Nol Kelvin.

Asesmen Kompetensi Minimum (AKM) merupakan salah satu alat yang digunakan untuk mengukur kemampuan peserta didik. Pada penelitian ini bertujuan untuk mengetahui perspektif peserta didik, guru dan calon guru fisika tentang AKM. Penelitian ini menggunakan desain mixed method yang dilakukan di SMAN 17 Surabaya dan Universitas Negeri Surabaya dengan memberikan angket dan wawancara. Penelitian dilakukan tanggal 25 November sampai 7 Desember 2021 sebanyak 103 responden. Teknik analisis data kuantitaf menggunakan uji Kaiser-Meyer-Olkin (KMO) dan Bartlett’s serta uji Cronbach’s Alpha Coefficient, sedangkan data kualitatif menggunakan reduksi, penyajian dan penarikan kesimpulan. Berdasarkan hasil analisis data penelitian didapatkan pada uji Kaiser-Meyer-Olkin (KMO) dan Bartlett’s sebesar 0,691 dan 0,584, adapun pada uji Cronbach’s Alpha Coefficient sebesar 0,782 dan 0,752. Dengan demikian penelitian ini valid dan reliabel. Perspektif peserta didik, guru dan calon guru fisika setuju dengan pelaksanaan AKM sebagai pengganti Ujian Nasional. Responden menyatakan soal AKM lebih kompleks daripada Ujian Nasional. AKM belum dapat dijadikan sebagai syarat kelulusan dan dasar acuan untuk merumuskan pendidikan di Indonesia karena masih baru diterapkan. Hal yang perlu dipersiapkan sebelum pelaksanaan AKM yaitu dengan memberikan bimbingan kepada peserta didik. AKM dapat diintegrasikan pada pembelajaran fisika. Dalam hal ini, materi fisika dikaitkan dengan kehidupan sehari-hari. Penelitian yang membahas hasil pelaksanaan AKM masih sedikit. Berdasarkan hasil penelitian diatas dapat disimpulkan peserta didik, guru dan calon guru fisika belum setuju AKM dijadikan sebagai dasar acuan maupun syarat kelulusan. Soal fisika dapat dijadikan seperti AKM yang mengaitkan dengan lingkungan. Penelitian yang terkait hasil pelaksaan AKM masih belum banyak, sehingga perlu adanya penelitian lebih lanjut.

Pandemi covid-19 menyebabkan banyak perubahan pada seluruh aspek kehidupan termasuk pendidikan yang tetap terlaksana melalui sistem pembelajaran online yang bersifat terbatas. Keterbatasan ini mendasari munculnya alternatif kurikulum yang relevan berupa penyederhanaan kurikulum 2013 revisi. Penelitian ini bertujuan untuk menganalisis implementasi Kurikulum Satuan Pendidikan Dalam Kondisi Khusus pada mata pelajaran fisika SMA serta respon peserta didik, guru, dan mahasiswa terhadap penyederhanaan tersebut. Metode yang digunakan adalah mixed method menggunakan teknik Explanatory Factor Analysis (EFA) dengan uji Kaiser-Meyer-Olkin (KMO) untuk mengetahui kevalidan instrumen serta uji Cronbach Alpha untuk mengetahui reliabilitas instrumen. Analisis deskriptif kualitatif juga dilakukan dari hasil wawancara peserta didik, guru, dan mahasiswa. Hasil analisis faktor dengan uji Kaiser-Meyer-Olkin (KMO) dan uji Cronbach Alpha menunjukkan bahwa instrumen telah valid dan reliabel sehingga dapat digunakan dalam penelitian. Hasil analisis angket dan wawancara menunjukkan bahwa kurikulum satuan pendidikan dalam kondisi khusus telah terlaksana dengan baik. Hal ini dilihat dari kuantitas peserta didik saat pembelajaran hybrid dan reduksi waktu pembelajaran, akan tetapi menurut responden kompetensi dasar yang digunakan dianggap tidak perlu disederhanakan untuk mempertahankan kualitas kompetensi peserta didik. Berdasarkan hasil analisis, dapat disimpulkan bahwa Implementasi Kurikulum Satuan Pendidikan Dalam Kondisi Khusus telah terlaksana dengan baik. Peserta didik, guru, dan mahasiswa mendukung implementasi Kurikulum Satuan Pendidikan Dalam Kondisi Khusus selama pembelajaran online atau hybrid learning dilaksanakan dengan tetap menggunakan kompetensi dasar pada Kurikulum 2013 Revisi.

Authors: Nasution Muhammad Furqon Amin Al Rasyid , Suliyanah Suliyanah
Published: July 2022

Pembelajaran masa kini masih terlalu terfokus pada penghafalan konsep dan penghafalan rumus, sehingga pembelajaran fisika kurang bermakna. Pada dasarnya ada berbagai model pembelajaran yang dapat memperkuat pendekatan serta memenuhi kebutuhan Kurikulum 13 (revisi). Salah satunya adalah model pembelajaran inkuiri terbimbing. Penelitian ini bertujuan untuk mengetahui seberapa besar pencapaian efektifitas pembelajaran menggunakan model pembelajaran inkuiri terbimbing. Metode penelitian yang digunakan Pre Experimental Design dengan rancangan one group pretest-posttest design yang dilakukan pada satu kelas tanpa perbandingan. Untuk mengetahui hasil pengujian hipotesis dilakukan uji-t, yang didapatkan nilai thitung  >  ttabel (16,715> 2,045). Keputusan dari pengujian tersebut adalah tolak H0 dan terima H1 sehingga dari data tersebut dapat dikatakan bahwa terjadi perubahan signifikan pada hasil uji akhir (post-test). Untuk mengetahuai seberapa besar pencapaian efektifitas model pembelajaran inkuiri terbimbing dilakukan uji N-Gain yang didapatkan nilai 0,56 termasuk kategori “sedang”. Hasil penelitian menunjukan bahwa penerapan model pembelajaran inkuiri terbimbing memberikan pengaruh postif terhadap peningkatan hasil belajar peserta didik.
