Indonesian Justice System for Election Crimes
Authors: Juhana Ujuh , Setiadi Edi , Yusdiansyah Efik
Published: October 2022

Violations of the criminal provisions in the election law give birth to election crimes. For the occurrence of election crimes, the state is obliged to carry out law enforcement efforts. Law enforcement against election crimes is carried out by legal apparatus authorized by the election law, namely the integrated law enforcement center (gakumdu). The integrated law enforcement center consists of the election supervisory body (Bawaslu), the police, and the prosecutor’s office. Election law enforcement is very important, especially in terms of the handling, investigation, prosecution, judicial, and sentencing processes. The law enforcement process is always identical to the current criminal justice system. In law enforcement for election crimes, the characteristics of law enforcement are different from criminal law enforcement in general. The methodology used in this paper uses a descriptive juridical method.

Validity of Mortgage Rights Based on Credit Agreement Aspects
Authors: Husein Ahmadi Muh , Ayu Ketut Rachmi Handayani Gusti , Karjoko Lego
Published: October 2022

Mortgage is an important part of civil law in economic legal activities. There are four stages of the interweaving of law in this relationship, namely pre-agreement, agreement, authorization of implementation, and the elimination of mortgage. In all these phases, creditors and debtors have equal rights, because the relationship between them is consensual (balanced law) because the parties assume ownership of each other. But in the practice of mortgage rights so far, the creditor takes a dominative position so that the application of the procedure does not provide justice to the debtor. This study provides answers about how to formulate legal renewal so that the relationship of mortgage rights can be intertwined on the basis and principles of procedural justice. This type of research is explanatory, with its empirical normative nature, using sources of normative legal materials and expert opinions. It is hoped that the output of this research is to guarantee academic honesty and provide empirical benefits, which is to be a source of strengthening and law-making for the mortgage and financial rights in Indonesia.

Published: October 2022

A compreensão dos padrões resultantes do dinâmico processo de mudanças da cobertura vegetal e de uso da terra na Amazônia são de relevância estratégica como ferramenta de subsídio à conservação da floresta. Além disso, tais informações podem ser aliadas ao estabelecimento de noções de desenvolvimento econômico sustentável para a região. O objetivo deste estudo foi analisar, a partir da zona de expansão da fronteira agropecuária no estado no Pará, a intensidade da transformação do uso das áreas de florestas naturais; através da ocupação por atividades antrópicas como a implantação de pastagem, agricultura e mineração em detrimento da diminuição das áreas florestadas, ao longo de uma série histórica de trinta e quatro anos (1985 até 2018). Os dados utilizados são de sensoriamento remoto de alta resolução espacial e temporal, produzidos a partir da Collection 4 do Projeto MapBiomas para o estado do Pará. A prática de ocupação territorial mais significativa e em maior ascensão no decorrer dos 34 anos analisados foi a de implantação de pastagens para a produção pecuária. A qual ao término do ano de 2018 tinha área ocupada equivalente a 200.000 Km2, um aumento de 400% em relação ao ano inicial observado (1985). Um comportamento inversamente proporcional ao ocorrido com as áreas de cobertura florestal, que ao longo dos 34 anos analisados perderam o equivalente a 160.000 Km2.

A hidrelétrica Belo Monte causou o deslocamento territorial dos ribeirinhos que habitavam as ilhas ao longo do rio Xingu. Com a interrupção dos modos de vida, passaram a lutar pela reconstrução do território. O objetivo do presente artigo foi realizar um diagnóstico dos agroecossistemas ribeirinhos na região Xingu    e    identificar    o   seu papel na  conservação da biodiversidade. Realizaram-se pesquisa de campo nas comunidades com entrevistas, turnês guiadas e levantamento etnobotânico. Participaram 71 unidades familiares, das quais 42 estavam reassentadas em 10 comunidades, perfazendo a amostra da presente análise. Observou-se diversidade de campos manejados, de espécies vegetais e animais, de trabalho e de produtos em cada agroecossistema familiar. Os ribeirinhos estão plantando agrobiodiversidade, que é parte vital da biodiversidade. Identificaram-se 93 espécies de plantas alimentícias, conservadas em espaços agroflorestais. O território garantido na beira do rio é o grande precursor para a formação dos agroecossistemas.

Analisou as caracteriticas dos sistemas de produção dos pequenos produtores que vem desenvolvendo o manejo do bacurizeiros (Platonia insignis Mart.) no Nordeste Paraense e Marajó. A escolha das Mesorregiões do Nordeste Paraense e Marajó decorreu da informação de que são áreas produtoras que respondem pela maior oferta de frutos de bacuri no estado do Pará. Para realização do levantamento de campo, optou-se por uma amostragem intencional, considerando-se somente os pequenos produtores que possuíam bacurizeiros nos seus estabelecimentos. Foram aplicados ao total 77 questionários entre os 7 municípios estudados, sendo 57 na Mesorregião Nordeste Paraense e 20 no Marajó. Verifica-se que a partir do levantamento socioeconômico realizado nas Mesorregiões do Nordeste Paraense e Marajó, foram analisados os dados de maior relevância que permitisse gerar o perfil dos agricultores que realizam o manejo de bacurizeiros e que realizam algum tipo de comercialização dos frutos ou da polpa de bacuri. Conclui-se ainda que o manejo de bacurizeiros constitui uma estratégia familiar importante para a manutenção das famílias no campo e apresenta potencial de crescimento capaz de atender demanda de exportação, importante para geração de renda.

O objetivo desse trabalho foi avaliar a qualidade dos frutos de plátano, cultivar D’Angola, produzidos em consórcio com espécies arbóreas e em diferentes densidades de plantio. Para isso, o experimento foi delineado em faixas com quatro arranjos silvibananeiros, sendo: plátano (Musa spp. L.) com eucalipto Urocam VM01 (Eucalyptus urophyla S.T. Blake x E. camaldulensis Dehnh.); plátano com casuarina (Casuarina equisetifolia L.); plátano com taxi-branco (Tachigali vulgaris L.F. Gomes da Silva & H.C. Lima) e plátano com acácia (Acacia mangium Willd.). Em cada faixa foram distribuídas ao acaso três densidades de plantio de plátano, sendo: 1.250, 833 e 650 plantas/ha, constituído o tratamento secundário. O plantio solteiro (monocultura) de plátano cv. D’Angola, foi utilizado como testemunha no espaçamento 4,5 m x 2,0 m x 1,6 m (1.923 plantas/ha). Avaliaram-se os seguintes aspectos físicos e físico-químicos dos frutos: massa do buquê, massa do fruto, massa da polpa, comprimento do fruto, diâmetro do fruto, diâmetro da polpa, relação polpa/casca, rendimento da polpa, firmeza da polpa, espessura da casca, sólidos solúveis totais (SST), acidez total titulável (ATT) e relação SST/ATT (ratio). Concluiu-se que o plátano produzido no sistema silvibananeiro apresenta menor massa e comprimento do fruto, quando comparado com o cultivo solteiro. Por outro lado, os frutos atenderam o padrão de qualidade para comercialização, independente da espécie arbórea utilizada no sistema. A densidade de plantio não surtiu efeito na qualidade dos frutos de plátano cv. D’Angola.
Is osteophyte located in the inferior of the intermeniscal ligament an indication for the surgical treatment of degenerative meniscal tear?
Authors: ÖZBEK Emre Anıl , GEZER Mehmet Can , KARACA Mustafa Onur , KAVAK Mustafa , AKMEŞE Ramazan
Published: October 2022

Objectives: Our study aimed to determine how often the osteophyte located underneath the anterior intermeniscal ligament is observed in patients who underwent arthroscopic surgery due to degenerative meniscal tears, how often this osteophyte can be diagnosed by magnetic resonance imaging, and whether this osteophyte could be an indication for the surgery to be performed for degenerative meniscopathy.
Methods: Our retrospective study included 47 patients operated for degenerative meniscus tears between 2017 and 2018, with a minimum follow-up of 2 years. Visual analog scale (VAS), Lysholm knee, and Western Ontario Meniscal Evaluation Tool (WOMET) scores were applied to all patients included in the study preoperatively and at the postoperative 3rd, 6th, 12th, and 24th months. The operated patients were grouped into two groups with and without osteophytes beneath the anterior intermeniscal ligament in magnetic resonance imaging (Group A and B). Preoperative and postoperative values of the patients were compared among themselves.
Results: The average age of the patients included in our study was 57 (range: 42 to 72) years. Forty (85%) participants were female. Osteophyte was detected in 36.1% (n = 17) of the patients in preoperative magnetic resonance imagings (Group-A). There was a statistically significant difference between preoperative VAS, Lysholm, and WOMET scores and postoperative 3rd, 6th, 12th, and 24th months (p < 0.05). Mean follow-up time was 32 (range: 24 to 60) months.
Conclusions: We believe that arthroscopic control of the inferior intermeniscal ligament for the presence of any osteophytes in patients treated surgically for degenerative meniscal tears is one of the main steps of this surgery.
Wątki egzystencjalne w twórczości Bergmana

Ingmar Bergman wniósł do dyskusji o sztuce własną estetykę i autorski język. Zastanowię się, czy wykorzystywał filmowe medium do filozofowania w duchu egzystencjalizmu. Analizując Więzienie, Siódmą pieczęć, Tam, gdzie rosną poziomki, Gości Wieczerzy Pańskiej i Szepty i krzyki odwołuję się do: wypowiedzi artysty, interpretacji badaczy jego filmów i filozofii egzystencjalnej – Kierkegaarda, Sartre’a, Heideggera i Jaspersa. Perspektywa interpretacyjna, którą przyjmuję jest panoramiczna. Zakładam za Höök i Bergom-Larsson, że twórczość Bergmana stanowi spójną całość. W takiej perspektywie nie tylko ujawniają się związki filmów Bergmana z filozofią egzystencjalną, ale również jego filozoficzny punkt widzenia.
Coexistent Actinomycosis and Fungus Ball in the Maxillary Sinus: A Case Report
Authors: Kim Tae Hoon , Lim Eun Jung , Kim SungHee , Kim Aeri
Published: October 2022

Actinomycosis is rarely accompanied by fungus balls. It is difficult to distinguish between actinomycosis and a fungus ball due to their similar clinical and computed tomography scan results. Thus, a meticulous histopathological examination is required for definite diagnosis. We report a case of actinomycosis accompanied by a fungus ball, found incidentally in a patient without rhinologic symptoms. The patient was successfully treated with endoscopic sinus surgery, followed by short-term antibiotic therapy. We suggest that shortterm antibiotic therapy may be more appropriate than long-term antibiotic therapy based on our case study as well as several other studies.

Published: October 2022

Nasopharyngeal tuberculosis can arise from both a primary infection and a secondary spread via the lymphatic or hematogenous system from a primary pulmonary lesion. Primary nasopharyngeal tuberculosis is rare and difficult to detect earlier because of the nonspecific presentations of the disease. As upper airway tuberculosis can be contagious, early initial diagnosis and suspicion of the physicians are needed in clinical practice. Recently, we successfully diagnosed and treated the disease by antitubercular medications of two cases of primary nasopharyngeal tuberculosis. Herein, we report our experience with a literature review.

Published: October 2022

Background: Greengram Vigna radiata (L.) Wilczek, is an important legume crop that serves as a low-cost source of protein. The bruchid (Callosobruchus spp.) is a serious storage pest affecting greengram and other pulse crops. Thus, a study was designed to investigate bruchid resistance (Callosobruchus chinensis) in inter sub-specific derived lines of greengram and to identify chemical compounds responsible for resistance. Methods: The experimental material comprised of 200 inter sub-specific derived lines of F9 generation of VBN (Gg) 2 (susceptible to bruchid) × Vigna radiata var. sublobata/2 (resistant to bruchid) and a susceptible check variety. The bruchid screening experiment was carried out in completely randomized design and replicated twice with 50 seeds in each replication by adopting no choice test. Out of 200 lines evaluated for bruchid screening, seed damage due to bruchid was less than 20 per cent in 11 lines, identified as resistant. However, three resistant lines viz., GGISC 124, GGISC 140 and GGISC 150 were taken for further confirmation for bruchid resistance and GC-MS analysis to discover the chemical compounds conferring resistance (Clarus SQ 8C, Perkin Elmer). Result: In confirmation screening, seed damage due to bruchid (Callosobruchus chinensis) on 30th day was less than 20 per cent in three inter sub-specific lines viz., GGISC 124, GGISC 150 (17.00%) and GGISC 140 (18.00%), whereas the susceptible check [VBN (Gg) 2] reached 100 per cent adult emergence. The three inter sub-specific lines recorded susceptibility index of 0.046 (GGISC 124), 0.047 (GGISC 140) and 0.048 (GGISC 150) and classified as resistant. The susceptible check [VBN (Gg) 2] recorded the susceptibility index of 0.085. GC-MS study was carried out in resistant lines GGISC 124, GGISC 140, GGISC 150 and susceptible check VBN (Gg) 2. The results revealed that the existence of three compounds viz., 9,12-octadecadienoic acid, methyl ester; Hexadecanoic acid, 1-(hydroxymethyl)-1, 2-ethanediyl ester and Hexadecanoic acid, 2-oxiranyl methyl ester in resistant lines conferred resistance against C. chinensis in greengram.
Tools for solving systems of non-linear equations
Authors: Caligaris Marta Graciela , Laugero Lorena Fernanda
Published: October 2022

When teaching numerical techniques in courses of numerical analysis of engineering careers at the Facultad Regional San Nicolás, little emphasis is placed on the mechanical procedures of the methods. Some math programmes offer the ability to design custom graphical interfaces. Taking advantage of this possibility, the Engineering & Education Group has been developing a collection of personalised graphical interfaces related to the different topics of numerical analysis. The use of these apps in the classroom allows for generating situations where students can appreciate the importance of applying different numerical methods and discussing different involved concepts. This paper presents the apps that have been designed and a sequence of activities that will be assigned, using the apps, to learn how to obtain approximate solutions to systems of non-linear equations. Rubrics designed to analyse the degree of development of mathematical competencies that the students are expected to acquire after the proposed activities will also be shown.

Published: October 2022

For a long time, studies to describe the communities’ composition and understand their dynamics implied great methodological challenges and the complete information that was sought was not always generated. However, in the recent past great advances have been made focused on the study of genomes and thus characterize not only the species, but the populations that comprise them. In this way, Population Genetics studies considers the environment to understand the mechanisms that generate the population fragmentation of a species, giving rise to the Molecular Ecology. Considering some studies as an example, we describe how molecular data can be complementary with data obtained through traditional methods used in Ecology. All this has contributed to the design of better management and conservation plans, which must be imperative to apply in the countries that lead the biodiversity ranking.
La tortuga blanca y la perturbación antropogénica en el Caribe Mexicano

Published: October 2022

Sea turtles are long-lived and charismatic animals, but are sensitive to anthropogenic activities. In the Mexican Caribbean, these organisms face threats derived from human activities, particularly since the 20th century. Sea turtles in the Mexican Caribbean inhabit coral reefs and seagrasses, which play an important role in regulating populations. The coast of Quintana Roo is the nesting and foraging habitat of four of the seven species of sea turtles. Swimming with sea turtles is offered as part of ecological tourism, one of the most important economic activities in the State. Very little is known about how chemical contaminants that reach the sea can affect the health of sea turtles. Being categorized as threatened species in the red list of the International Union for Conservation of Nature (IUCN, 2021) and in the official Mexican standard (NOM-059-SEMARNAT-2010), it is necessary to explore methods capable of showing biochemical changes by the presence of toxic agents, but that are not invasive, such as oxidative stress biomarkers. This manuscript presents the situation faced by sea turtles and their habitat in the Mexican Caribbean and discusses the ecotoxicological studies carried out to date on the white turtle (Chelonia mydas) in this region.

Penerapan algoritma Dinkelbach dan transformasi Charnes Cooper pada pemrograman fraksional linear di UD Bintang Furniture
Authors: Musthofa Muhammad Wakhid , Safitri Evira Dian
Published: October 2022

Linear fractional programming is a special case of non-linear programming with an objective function consisting of the ratio of two linear functions. The problem can be solved using the Dinkelbach algorithm and the Charnes Cooper transformation. The essence of these two methods is to convert the problem of linear fractional programming into a linear programming problem which then provides an optimal value of each variable in its objective function. In this study, we will solve the problem of linear fractional programming at UD Bintang Furniture, that is to determine the optimal value of the comparison between profits and production costs of the company. The results show that the Dinkelbach algorithm method requires more iterations than Charnes Cooper's transformation. Despite this, both methods produce the same optimal value.

Published: October 2022

This study aims to apply time series graphs on stock of Astra Agro Lestari Tbk. and Anadolu Group with last observation carried forward (LOCF) imputation. The imputation was used because the data for the two companies had missing values on several dates. Missing value contained in the company Astra Agro Lestari Tbk. in Indonesia more than Anadolu Group in Turkey because of the difference in the number of holidays. Original data and data with complete dates are combined to form new data where missing values are seen on certain dates. The function used in the R program to form the graph is xts. However, the Date variable has a character class so it needs to be changed to the Date class. The xts function will error if the class is not changed. The modification also causes the horizontal axis of the graph to be replaced by the date. Based on the chart of stock prices and transaction volume of stock of the company Astra Agro Lestari Tbk. and Anadolu Group experienced increases, decreases, and is constant on several dates.

Therefore, this study aims to determine the appropriate model in estimating the Infant Mortality Rate (IMR) and to find out the factors that influence the IMR in Indonesia. The data in this study was secondary which obtained from the Indonesia Health Profile. The estimation was carried out using Geograpically Weigthed Regression (GWR) and Mixed Geographically Weigthed Regression (MGWR) models. The GWR model is development of regression that consider spatial factors. While the MGWR model is a combination of regression and GWR with several variables influence locally. but the rest goes globally. The result showed that the MGWR model was the best model compared to the GWR model with the lowest AIC value selection standart. The MGWR model with weighted Adactive Kernel Gaussian found that locally influencing factors were infants who were exclusively breastfed (ASI) and infants who received early initiation of breastfeeding (IMD), while globally influencing factors were infants who were given vitamin A, low birth weight (LBW) delivery services at health facilities and pregnant women receiving bloodsupplementing tables (TTD).

Teacher leadership and student achievement in South Korea and the United States
Authors:   Korean Comparative Education Society, Woo Hansol
Published: October 2022

[Purpose]This study examines the relationship between teacher leadership (TL) and student achievement in the US and Korea. TL is defined by two primary practices: (a) supporting professional learning of peers (i.e., collaboration, coordination) and (b) influencing school decisions (i.e., distributed leadership, decision-making responsibility).
[Methods]Using the 2015 PISA data, this study utilized hierarchical linear modeling (HLM) to analyze the TL practices by comparing the two countries.
[Results]The present study found that the two TL practices (i.e., peer learning and decision-making) were weakly correlated to each other in both countries. HLM analysis indicated that only decision-making responsibility was statistically related to higher student achievement in the US. In Korea, collaboration was negatively related to student achievement, while coordination was positively associated with student achievement.
[Conclusion]The implications for theory and policy were discussed, including the concept of TL and the complex natures of the relationships between TL and student achievement in different countries.

Published: October 2022

Purpose: To verify the biological effects including anti-aging and anti-inflammatory effects, of fermented plant root extract mixtures that were measured in vitro.Method: To select the most effective plant root extract, the effects of DPPH free radical scavenging were measured. The mixture (MC) of selected plant roots was fermented with Saccharomyces cerevisiae (S. cerevisiae) (MF). Reverse transcription (RT)-PCR was performed on human dermal fibroblast to measure the effects of MC and MF on the mRNA expression of COL1A1 and hyaluronic acid synthase 2 (HAS2) and on the anti-inflammatory-related gene expressions such as cyclooxygenase-2 (COX-2), interleukin-6 (IL-6), and tumor-necrosis factor (TNF)-α. Additionally, we also tested the cell renewal and proliferation for skin cell migration. Student's t-test was performed for statistical analysis, and results were expressed as mean ± standard deviation.Results: Among 15 root extracts, those of Taraxacum officinale (T. officinale) rhizome, Arctium lappa (A. lappa), Anemarrhena asphodeloides (A. asphodeloides), Pueraria lobata (P. lobata), and Nelumbo nucifera (N. nucifera) were selected based on the effect of DPPH free radical scavenging. The mRNA expression levels of COL1A1 and HAS2 were increased by MC and MF in a concentration-dependent manner. MC and MF showed cell renewal and proliferation. Inflammation-related genes were inhibited by MC or MF in a concentration-dependent manner (TNF-α, IL-6, and COX-2).

Introduction: Chronic obstructive pulmonary disease (COPD) is a high disease burden and negatively impacts the bio-psycho-social well-being of patients, such as anxiety, depression, and shortness of breath. Anxiety and depression can increase morbidity and worsen the condition and health status of the patient. This systematic review aimed to analyze the effect of walking exercises with breathing control on the degree of shortness of breath, anxiety, and depression in COPD patients.
Methods: The data sources were taken from EBSCO, PubMed, and ProQuest using related keywords. Articles were selected using the preferred reporting items for systematic reviews and meta-analyses (PRISMA) diagram method.
Results: Ten articles in this systematic review obtained three intervention categories: 1) intervention combined walking exercises with breathing control can be performed 30 minutes per session 2-3 times a week; 2) walking exercise intervention is performed thrice a week for 30-45 minutes per session; 3) breathing control exercise intervention is performed 10-30 minutes with a duration of 2 times a day in the morning and night or can be performed three times a week. Those three intervention categories significantly reduced the degree of shortness of breath, anxiety, and depression in COPD patients.
Conclusion: Findings from this systematic review suggest that walking exercise intervention in COPD patients can help reduce the degree of shortness of breath, anxiety, and depression.

Islam and Human Rights: Friend or Foe?
Authors: Abshar Fariz Ulul , Khanif Al , Efendi A'an , Muktafi Muktafi
Published: October 2022

In the context of the relationship between Islam and democracy along with human rights, Islam represents two opposing positions (the two faces of Islam). On the one hand, Islam is seen as a religion of compassion (raḥmat li al-‘ālamīn), respects plurality, upholds tolerance and cares about human rights. On the other hand, Islam is often identified with separatism, discrimination, intolerance and violent phenomena. In Islamic countries and Muslim-majority countries, violations of human rights frequently occur. Islam often appears with a double face. In addition to being a source of law to bring about peace, it is often used as the basis for violent ideologies from state’s repressive policies to terrorism movements. This article elaborates on the basic concept of human rights in Islam and the dynamics of protecting and upholding human rights. Using a conceptual approach, this study aims to seek religious awareness in the midst of globalization where religion can strengthen the concepts of human rights. When religion is used as a source in the rational policy framework of a country, especially the protection and enforcement of human rights, it can be ascertained that human rights in that country will flourish and will be accepted by the citizens.

Authors: Nugroho Puspo , Fatah Ahmad , Hidayat Aat
Published: October 2022

This study aims to determine the perception of Fiqh teachers on changes in Khilafah material, radicalism in material content, and learning strategies for Khilafah material. The methodology employed in this research was a qualitative approach using a multistrategy, namely interviews, documentation, and observation. This study’s results revealed that at the first point regarding teachers’ perceptions of the policy, they tended to agree that there were several suggestions at the level of academic concepts, such as the need to be given a special space for Fiqh Siyasah content. Second, in the Khilafah material at Minister of Religion Decree (Keputusan Menteri Agama, KMA) Number 165 of 2014, absolutely no elements lead to radicalism. It all depended on how the teacher taught it. On the third point, it is more in the nature of adapting to the context in which Indonesia stands through discussion forums, is not rigid in using learning resources, and accommodates learning resources for the Qur’an and Hadith, Ijma’, Qiyas, Istihsan, Istishab, Maslahah Mursalah, ‘Urf, and some under the context of the Fiqh learning material.

The marine record of the Triassic–Jurassic boundary interval has been studied extensively in shallow-marine successions deposited along the margins of Pangea, particularly its Tethyan margins. Several of these successions show a facies change from carbonate-rich to carbonate-poor strata attributed to the consequences of igneous activity in the Central Atlantic Magmatic Province (CAMP), which included a biocalcification crisis and the end-Triassic mass extinction. Evidence for a decline in calcareous and an increase in biosiliceous sedimentation across the Triassic–Jurassic boundary interval is currently limited to the continental margins of Pangea with no data from the open Panthalassan Ocean, the largest ocean basin. Here, we present a facies analysis of the McCarthy Formation (Grotto Creek, southcentral Alaska), which represents Norian to Hettangian deepwater sedimentation on Wrangellia, then an isolated oceanic plateau in the tropical eastern Panthalassan Ocean.

The facies associations defined in this study represent changes in the composition and rate of biogenic sediment shedding from shallow water to the outer ramp. The uppermost Norian to lowermost Hettangian represent an ∼ 8.9-Myr-long interval of sediment starvation dominated by pelagic sedimentation. Sedimentation rates during the Rhaetian were anomalously low compared to sedimentation rates in a similar lowermost Hettangian facies. Thus, we infer the likelihood of several short hiatuses in the Rhaetian, a result of reduced input of biogenic sediment. In the Hettangian, the boundary between the lower and upper members of the McCarthy Formation represents a change in the composition of shallow-water skeletal grains shed to the outer ramp from calcareous to biosiliceous. This change also coincides with an order-of-magnitude increase in sedimentation rates and represents the transition from a siliceous carbonate-ramp to a glass ramp ∼ 400 kyr after the Triassic–Jurassic boundary. Sets of large-scale low-angle cross-stratification in the Hettangian are interpreted as a bottom current–induced sediment drift (contouritic sedimentation). The biosiliceous composition of densites (turbidites) and contourites in the Hettangian upper member reflects the Early Jurassic dominance of siliceous sponges over Late Triassic shallow-water carbonate environments. This dominance was brought about by the end-Triassic mass extinction and the collapse of the carbonate factory, as well as increased silica flux to the ocean as a response to the weathering of CAMP basalts. The presence of a glass ramp on Wrangellia supports the hypothesis that global increases in oceanic silica concentrations promoted widespread biosiliceous sedimentation on ramps across the Triassic to Jurassic transition.
