Pesisir Kabupaten Kendal sebagai pesisir Muara Kali Bodri, dengan adanya angkutan sedimen yang terendap di muara sungai berpotensi terjadi proses sedimentasi. Morfologi pantai yang menjorok ke arah laut berpotensi terjadi abrasi, sehingga berdampak terhadap pola perubahan garis pantai. Tujuan penelitian adalah untuk mengetahui wilayah rentan abrasi/akresi pantai di Muara Sungai Kali Bodri periode tahun 2014 – 2019. Metode penelitian ini merupakan penelitian studi kasus dengan analisis secara kuantitatif dengan pendekatan multi temporal citra satelit menggunakan perangkat lunak Digital Shoreline Analysis System (DSAS). Data penelitian meliputi pasang surut, batimetri, gelombang, angin, nilai D50 sedimen dasar, garis pantai tahun 2014-2016 dengan citra Landsat 8 dan tahun 2016-2019 dengan Citra Sentinel 2A. Hasil penelitian menyatakan bahwa perubahan garis pantai pada tahun 2014-2016 terjadi akresi sebesar 12,80 ha dan abrasi sebesar 2,93 ha, sedangkan perubahan garis pantai pada tahun 2016-2019 terjadi akresi seluas 9.88 ha dan abrasi seluas 3.35 ha. Total perubahan garis pantai tahun 2014–2019 mengalami akresi pantai seluas 22,68 ha dan mengalami abrasi seluas 6,28 ha, sehingga disimpulkan proses akresi pantai lebih dominan seluas 16,40 ha. Coastal of Kendal Regency as the coast of Kali Bodri Estuary, with sediment transport in the river estuary has the potential to cause sedimentation. Beach morphology that protrudes towards the sea has the potential to cause abrasion, thus affecting the pattern of changes in the coastline. The purpose of this study was to determine the area of prone to abrasion/accretion of beaches in the Kali Bodri River in the period 2014 - 2019. This research method is a case study research with a quantitative analysis with a multi-temporal approach to satellite imagery using the Digital Shoreline Analysis System (DSAS) software. The research data includes tides, bathymetry, waves, wind, D50 values of basic sediments, coastlines in 2014-2016 with Landsat 8 imagery, and in 2016-2019 with Sentinel 2A imagery. The results of the study stated that changes in the coastline in 2014-2016 occurred accretion of 12.80 ha and abrasion of 2.93 ha, while changes in the coastline in 2016-2019 occurred accretion of 9.88 ha and abrasion of 3.35 ha. The total shoreline changes in 2014-2019 underwent beach accretion of 22.68 ha and experienced abrasion of 6.28 ha, which concluded that the beach accretion process was more dominant at 16.40 ha.

Pantai Bandengan merupakan salah satu pantai wisata di Kabupaten Jepara dimana terjadi aktifitas pembangunan yang cukup massif sejak beberapa tahun terakhir yang bertujuan untuk menunjang kegiatan rekreasi wisatawan. Namun terdapat ancaman dalam pengembangan sektor wisata tersebut berupa perubahan garis pantai yang disebabkan oleh sedimentasi dan abrasi yang dapat mengganggu perekonomian masyarakat yang memiliki mata pencaharian di wilayah tersebut. Tujuan penelitian ini yakni untuk mengetahui dampak sedimentasi dan abrasi terhadap luas daratan serta mengidentifikasi wilayah-wilayah yang rawan terhadap perubahan garis pantai. Metode yang digunakan yaitu interpretasi citra satelit Google Earth Pro serta survei lapangan menggunakan alat Sediment trap dan bola duga. Pengolahan data citra diproses menggunakan software ArcGIS 10.2 untuk mendapatkan luasan wilayah sedimentasi serta abrasi. Sediment trap digunakan untuk mendapatkan laju sedimentasi dan karakteristik sedimen. Berdasarkan hasil penelitian, dalam lima tahun terakhir sejak 2015 hingga 2019 terjadi sedimentasi seluas ± 8062,9 m2, sedangkan abrasi seluas ± 12.502,1 m2. Sedimen penyusun perairan didominasi oleh lanau pasiran serta kecepatan arus permukaan berkisar 0,085 m/s hingga 0,197 m/s. Bandengan beach is one of the tourist beaches in Jepara Regency where there have been massive development activities since the last few years aimed at supporting tourist recreational activities. However, there is a threat in the development of the tourism sector in the form of changes in the coastline caused by sedimentation and abrasion that can disrupt the economy of people who have a livelihood in the region. The purpose of this research is to determine the impact of sedimentation and abrasion on land area and identify areas that are prone to shoreline changes. The method used is the interpretation of Google Earth Pro satellite imagery and field surveys using a Sediment trap and floating ball. Image data processing is processed using ArcGIS 10.2 software to get the area of sedimentation and abrasion. Sediment traps are used to obtain sedimentation rates and sediment characteristics. Based on the results of the study, in the last five years since 2015 until 2019 there is a sedimentation area of ± 8.062,9 m2, while abrasion area of ± 12.502,1 m2. The constituent sediments of the waters are dominated by the sandy silt and surface current velocity ranges from 0.085 m/s to 0.197 m/s.

Sumberdaya ikan pelagis diduga merupakan salah satu sumberdaya perikanan yang paling melimpah di perairan Indonesia. Perairan Kabupaten Jepara memiliki sumberdaya ikan pelagis yang cukup potensial khususnya ikan teri (Stolephorus sp). Banyak faktor yang menyebabkan belum optimalnya produksi ikan di Jawa Tengah. Faktor penyebab diantaranya sistem tangkap nelayan yang masih tradisional. pada umumnya daerah penangkapan ikan tidak ada yang bersifat tetap, selalu berubah dan berpindah mengikuti pergerakan kondisi lingkungan, yang secara ilmiah ikan akan memilih habitat yang lebih sesuai dan banyak terdapat makanan demi kelangsungan hidupnya. Fitoplankton merupakan tumbuhan sel tunggal berukuran mikroskopik yang sangat berperan dalam menunjang kehidupan didalam perairan dan berfungsi sebagai sumber makanan organisme perairan. Metode yang digunakan dalam penelitian ini adalah metode kuantitatif. Data yang digunakan dalam penelitian ini diolah lalu ditampilkan dalam bentuk grafik, gambar, maupun tabel, seperti data klorofil-a, SPL, arus dan angin. Berdasarkan hasil analisis, faktor klorofil-a dan SPL sangat berpengaruh terhadap hasil tangkapan ikan teri di perairan Kabupaten Jepara. Hasil analisis klimatologi menunjukkan adanya hubungan yang sangat kuat, dengan nilai korelasi sebesar 0,844 untuk klorofil-a dan -0,867 untuk SPL, sementara faktor angin dan arus menunjukkan hubungan dengan tingkat korelasi sedang. Nilainya sebesar 0,612 untuk angin dan 0,458 untuk arus.

Ekosistem mangrove termasuk ekosistem yang sangat produktif dan dapat berkontribusi sebagai penyimpan karbon organik pada sedimen. Lepasan serasah yang jatuh ke dasar akan menjadi bagian Sedimen. Serasah yang berguguran akan mengalami dekomposisi dan membentuk karbon organik. Jenis mangrove yang tumbuh dalam suatu ekosistem dipengaruhi oleh distribusi ukuran butir. Setiap jenis mangrove memiliki karakteristik pertumbuhan spesifik. Hal ini akan berpengaruh terhadap kemampuan penyimpanan bahan organik dan secara langsung dapat mempengaruhi kontribusi konsentrasi bahan organik dalam sedimen. Penelitian ini bertujuan untuk mengetahui simpanan karbon organik total dalam sedimen di daerah vegetasi mangrove Karimunjawa. Penelitian dilakukan pada 29 September – 3 Oktober 2020. Analisis data meliputi analisis karbon organik total dengan metode LOI (Lost of Ignition), densitas sedimen (Bulk Density), pH sedimen dan ukuran butir sedimen menggunakan metode granulometri. Hasil penelitian menunjukkan rata-rata simpanan karbon organik secara vertikal di dekat aliran sebesar 172,72 ton/ha, sedangkan yang jauh dari aliran yaitu 76,17 ton/ha. Simpanan karbon organik ditentukan oleh variabel terikat yaitu bulk density, kandungan karbon dan kedalaman sampel. Faktor lain yang mempengaruhi simpanan karbon organik yaitu pH sedimen, ukuran dan jenis partikel.

Über den Anfang von Walter Benjamins Aufsatz „Zur Kritik der Gewalt“ anlässlich des hundertjährigen Jubiläums seiner Veröffentlichung
Authors: Fenves Peter 
Published: January 2022

AbstractAs a commentary on the initial paragraph of Benjamin’s “Zur Kritik der Gewalt,” this article shows that its characterisation of the “sphere of moral relations” as circumscribed by the poles of law and justice generates the rationale for the critique of violence. After describing how Benjamin reproduces the structure of Kant’sMetaphysik der Sitten, the article outlines the procedure whereby the initial definition ofGewaltas an “intervention” into moral relations is supplemented by an exposition of the situation in which law “encroaches” upon “the living” by presenting itself as an “expiation” (Sühne) of moral ambiguity; but inasmuch as the sphere of moral relations is constitutively split between the mutually repugnant poles of law and justice, the process of expiation intensifies the ambiguity of the situation law purports to resolve. Benjamin’s solution to this dilemma consists in claiming the reality of “de-expiation” (Entsühnung), which he associates with “pure” and thus “divine” violence.
Verstörung und Vertrauen
Authors: Gutschmidt Rico 
Published: January 2022

AbstractProceeding from a philosophical interpretation of negative theology as performatively undermining our seeming understanding of the absolute and thereby evoking a transformative experience, this paper emphasises the philosophical significance of negative theology by linking it to Karl Jaspers’ notion of the universal limit situation of existence. Against this background, an analysis of mystical and psychotic experiences shows how certain similarities between the two can be understood as constituting a particular mental state in which the universal limit situation is experienced personally. Moreover, experiencing the limit situation, be it through this mental state or through certain moods or feelings, can be transformative and may lead to an attitude of groundless trust that acknowledges the incomprehensibility of the human condition. The paper argues that this reading of negative theology provides a better understanding of the parallels between mysticism and psychosis and may be fruitfully applied in therapy.
Die Verursachung der Vergangenheit
Authors: Hoffmann Christian Hugo 
Published: January 2022

AbstractHow can a present or future event causally influence one in the past? Even though the case of such a relationship is often quickly dismissed as impossible, this paper suggests that this reaction is hasty and omits interesting as well as substantive arguments and considerations. In an introductory synopsis of the metaphysics of causality, we first present and discuss arguments for and against the possibility of backwards causation. On the other hand, we suggest that a probabilistic notion of causality according to Suppes need not exclude that causes occur temporally after their effects.
Adrift between republican values and plurilingual policies: (pre)primary school teachers’ reported practiced language policies in Strasbourg
Authors: Flom Haley , Young Andrea S. 
Published: January 2022

Abstract
In France, education policies concerning children’s home languages have recently changed, with the country’s highly centralized and monolingual national education system now promoting inclusive language policies, specifically at the pre-primary level (M.E.N. (Ministère de l’Education Nationale). 2016. Statégie langues vivantes. 22 janvier 2016. Paris). However, such prescribed practices run contrary to historically rooted monolingual ideologies and interpretations of the values of the République (Hélot, Christine. 2008. « Mais d’où est-ce qu’il sort ce bilinguisme? » La notion de bilinguisme dans l’espace scolaire français. In Gabriele Budach, Jürgen Erfurt & Melanie Kunkel (eds.), Écoles Plurilingues – Multilingual schools: Konzepte, Institutionen und Akteure. Internationale Perspecktiven, 55–80. Frankfurt: Peter Lang). Understanding the policies and ideologies influencing teachers’ agency to implement inclusive language policies via their own classroom practices is vital to developing effective teacher education programs. In this paper, we analyze data from our research into pre-primary and primary school teachers’ attitudes, beliefs, and knowledge about their pupils’ plurilingualism and its place in the classroom, with the aim of answering the following research questions: what are some of the reported practiced language policies in these classrooms, and on which underlying ideological foundations have they been constructed? In order to uncover the ideological challenges to implementing plurilingual education approaches and language-supportive pedagogies, semi-directed interviews with eight pre-primary and primary school teachers working in low-resource contexts (primarily low-income families) were conducted, transcribed and analyzed using the constant comparative method.

Abstract
In this paper, a simple method for hydrophobic modification of polyvinyl alcohol (PVA) was found. Using N-methylpyrrolidone as solvent, PVA was esterified with stearyl chloride without catalyst. The modified hydrophobic polyvinyl alcohol (MPVA) was well verified by FT-IR and XRD. Using air filter paper as receiving substrate and MPVA as spinning solution, MPVA air filter paper with water resistance and high filtration performance was prepared, and hydrophilic PVA air filter paper was prepared as controlled sample. SEM was used to observe the fiber morphology on the surface of the two composite filter papers. The contact angle of hydrophobic MPVA air filter paper (25:3) was 121.9°, and the filtration efficiency was increased to 99.9955 % and the filter initial resistance increased to 90 Pa.
Torsional Overload Fracture of Twist-off Bolts During Assembly
Authors: Neidel A. , Gädicke T. , Ullrich T. 
Published: January 2022

Abstract
Supposedly simple cases of failure are most often best suited to communicate the principles of component failure analysis in the field of materials engineering to a wide readership, especially to those peers in the specialist community who are just beginning to familiarize themselves with the subject. The present case of failure relates to components that failed as early as during the assembly, and more specifically, during the final assembly stage of combustion chamber components for heavy-duty gas turbine engines. Hence, they lost their functionality (in fact, the common definition of component failure). At tightening torques of the nuts opposite of the tapered heads as low as below 25 Nm, so-called twistoff bolts which, when welded into combustion chamber sheets, take on the function of stud bolts, sheared off. By way of exception, a materialographic failure analysis could show that the primary cause of the failure was not the component’s design, but the disregard of the drawing specifications during final assembly. However, on a secondary level, design deficiencies had to be mentioned, as untempered welded joints in martensitic chromium steels invariably act as metallurgical notches. If the respective part is subjected to dynamic loads, as is the case in virtually all turbo machinery, they are thus to be avoided.
Changing discourses of climate change: building social-ecological resilience cross-culturally
Authors: Plastina Anna Franca 
Published: January 2022

Abstract
Social-ecological resilience (SER) is setting a new trend of thinking about environmental issues since it considers climate unpredictability as the norm in the Anthropocene and climate disturbance as offering opportunities for change. This paper argues that SER can be conceptualized as a function of narrative text and talk in the recent practice of online environmental activism. Based on a case study, the investigation explores a TED talk by the US environmentalist, Al Gore, and a web-based text by the Indian activist, Vandana Shiva, seeking how meanings of climate change enhance resilience building. A mixed-method research design is used to perform a discursive frame analysis on the sample discourses, guided by key resilience-building principles, and framed by the methods of critical discourse and frame analyses. The twofold aim is to analyse how micro-linguistic features mediate social-ecological memory and novelty as key SER drivers, and how macro-discursive frames are selected to shape meanings cross-culturally. Based on these findings, the comparative analysis at the socio-discursive level highlights how SER ideologies underpinning these discourses particularly diverge in the context of the Global North/Global South divide. Overall, the study findings shed light on the multiple meanings of SER shaping more constructive responses to climate change.
