Purpose: To report a case in which vision improvement was achieved following surgery for anterior displacement of the eyeball resulting from self-mutilation in a patient with schizophrenia.Case summary: A 37-year-old female patient with schizophrenia was admitted following an attempt at self-mutilation, which led to anterior displacement of her right eyeball. Initial evaluation revealed that reduction was not feasible and visual acuity was finger count at 20 cm in the right eye. Orbital computed tomography indicated 26-mm anterior displacement of the eyeball from the center of the cornea to the interzygomatic line along with a small retrobulbar hemorrhage and edema in the superior rectus muscle. Surgical intervention, consisting of lateral canthotomy, cantholysis, and tarsorrhaphy, was performed for correction. The surgical site was reconstructed 6 days after surgery. A fundus examination conducted 1 month later revealed no abnormalities and best-corrected visual acuity improved to 20/20.Conclusions: Globe subluxation due to self-mutilation is a very rare and urgent condition in both ophthalmic and psychiatric contexts that requires immediate surgical intervention. This case demonstrates that immediate anatomical reduction when there is no direct suspicion of optic nerve damage can be beneficial for the recovery of visual acuity and may lead to a favorable prognosis.

Purpose: To report a case of retrobulbar optic neuritis after COVID-19 infection.Case summary: A 20-year-old Korean man, without any previous relevant medical history, presented with sudden blurred vision in the left eye that began 6 days after a COVID-19 infection. At his initial visit, the best-corrected visual acuity in the left eye was counting fingers at 30 cm. The pupil showed a grade 2 relative afferent pupillary defect. The fundus exam was normal in both eyes. In the visual evoked potential (VEP) exam, the P100 amplitude of the left eye was decreased and delayed. Orbit magnetic resonance imaging showed asymmetric enlargement and mild enhancement in the left optic nerve. No other lesions were observed around the optic nerve. Steroid pulse therapy was started after a diagnosis of retrobulbar optic neuritis. After 1 month, the patient’s visual acuity had improved to 1.0 in the left eye. The relative afferent pupillary defect and visual field defect disappeared. On VEP, the P100 amplitude recovered, and the delay disappeared.Conclusions: Retrobulbar optic neuritis is a possible neuro-ophthalmological complication of COVID-19 infection. In such cases, high-dose steroid pulse therapy may be helpful, as in the treatment of other forms of optic neuritis.
Covenant Strictness Measures
Authors: Ding Jianglin Dennis , Witt Alan
Published: August 2024

Covenants are crucial components of loan agreements, designed to protect lenders by imposing various restrictions and obligations on borrowers. Despite extensive empirical research on covenant strictness, a universally accepted measure of covenant strictness remains elusive. Existing metrics tend to include only a limited selection of covenants from the comprehensive contract. This study utilizes loan-level credit risk data to evaluate and rank the effectiveness of several widely used covenant strictness measures. Credit risk at the loan level is assessed through two primary methods: the difference between issue ratings and issuer ratings, and the loan credit spread while controlling for fixed effects at the firm level. This approach allows for a more nuanced comparison and provides insights into which measures most accurately reflect covenant strictness and its impact on credit risk. The findings aim to contribute to a better understanding of covenant effectiveness, offering potential improvements for future loan contract structuring and risk assessment practices.

Semen menjadi salah satu kebutuhan utama manusia sebagai bahan konstruksi dalam pembangunan, baik di bidang perumahan, perhubungan, dan lain-lain. Namun semen dengan kualitas rendah akan berdampak pada kualitas pembangunan fisik suatu bangunan. Penelitian ini bertujuan menentukan konsentrasi 4 senyawa utama dalam semen terhadap 4 merk semen di kabupaten Alor yang dikodekan dengan c1, c2, c3, dan c4, dengan menggunakan X-RF dan dilanjutkan dengan analisis menggunakan stoikiometri Bogue. Hasil penelitian menunjukkan bahwa konsentrasi komponen kimia A (Al2O3) tidak ditemukan dalam semen dengan kode semen c1, c2, dan c3, serta konsentrasi komponen kimia (SO3) tidak ditemukan dalam semen dengan kode semen c1, c2, dan c4. Hasil analisis terhadap sampel c3 dan c4 menunjukkan tidak ditemukannya konsentrasi 2 senyawa utama dalam sampel semen yakni C2Sdan C3A. Hal ini dapat diduga bahwa semen kehilangan sebagaian senyawa akibat waktu dan jarak distribusi semen dari produsen ke distributor serta akibat situasi dan kondisi dalam lingkungan distributor.

Indonesian regulations regarding the implementation of B30 encourage a significant increase in biodiesel demand. Moreover, this implementation will continue to be increased to B35 in 2025 and is projected to reach B100 in 2045. This high demand for biodiesel needs to be supported by the development of adequate biodiesel production technology where the catalyst is one aspect that plays an important role in biodiesel production. The use of catalysts aims to accelerate biodiesel production so that high biodiesel yields and good quality are achieved. In biodiesel production, the choice of catalyst greatly influences the operating conditions, the products produced, the subsequent purification process, and the environmental impacts. Moreover, the changing trend in biodiesel raw materials from food to non-food ingredients requires the development of catalysts that are more suitable for the raw materials used in biodiesel production. The specific characteristics of each catalyst play an important role in the transesterification reaction to produce biodiesel where this needs to be supported and adapted to optimum operating conditions, especially in terms of alcohol-to-oil molar ratio, catalyst amount, temperature, pressure, and reaction time. This review provides a comprehensive overview of the various heterogeneous catalysts used to assist the transesterification reactions in biodiesel production.

Indonesia's high population and rapid economic growth are driving a major transformation in the transportation sector, which is in line with the high increase in fuel demand. The need for biofuel as a substitute for conventional fuel is increasingly being prioritized by considering sustainable development goals (SGDs). Biofuel has safer health and environmental impacts than conventional fuel but still has fuel performance that meets fuel standards and engine performance. Biofuels can be derived from a variety of more sustainable and abundant raw materials, such as biomass and vegetable oils. In this review biodiesel, hydrogenated vegetable oil (HVO), and direct vegetable oil (SVO) are discussed in depth regarding the transformation of their production processes and their impacts on health and the environment. Biodiesel is one of the most widely developed and implemented compared to HVO and SVO to encourage the use of renewable energy in various aspects of people's lives in Indonesia. These three biofuels have different fuel characteristics and performance but can continue to be developed in the future to increase the implementation of renewable energy more massively.

Biodiesel merupakan bahan bakar alternatif terbarukan dan bersifat ramah lingkungan. Prinsip pembuatan biodiesel adalah mengubah bahan baku trigliserida menjadi metil ester melalui reaksi transesterifikasi. Trigliserida dapat diperoleh dari minyak nabati dan lemak hewan. Pada penelitian ini biodiesel didapatkan dari proses esterifikasi dan transesterifikasi minyak nyamplung sebagai sumber minyak nabati. Proses esterifikasi dilakukan terlebih dahulu untuk mengurangi kadar asam lemak bebas pada minyak nyamplung yang awalnya memiliki kadar 26,27% hingga turun menjadi 1,71%. Selanjutnya dilakukan proses transesterifikasi untuk mereaksikan minyak nyamplung dengan methanol agar menghasilkan biodiesel menggunakan katalis heterogen yaitu zeolit dan bentonit yang telah dimodifikasi. Modifikasi katalis dilakukan dengan aktivasi zeolit dan bentonit alam menggunakan asam HCl pada suhu 100 oC selama 24 jam dan dilanjutkan kalsinasi pada suhu 550 oC selama 4 jam. Katalis zeolit dan bentonit hasil modifikasi kemudian dianalisis karakteristiknya menggunakan uji XRD dan FTIR. Proses transesterifikasi untuk memperoleh biodiesel berlangsung pada suhu 50, 60, 65, dan 70˚C selama waktu reaksi 5 jam. Hasil biodiesel dengan perolehan terbesar didapatkan pada suhu 60 oC, yaitu sebesar 88,19% menggunakan katalis zeolit termodifikasi, 78,84% menggunakan katalis bentonit termodifikasi dan 82,36% menggunakan campuran katalis zeolit dan bentonit termodifikasi pada rasio 1 : 1. Biodiesel hasil pada perolehan terbesar dengan katalis zeolit termodifikasi dilakukan pengujian karakteristiknya sesuai parameter SNI, dan mendapatkan hasil yaitu memiliki densitas 887 kg/m3, viskositas 5,633 mm2/s, bilangan setana 53, titik nyala pada suhu 121˚C, dan kadar metil ester sebesar 94,55%.

Practising democracy in agrifood collectives
Authors:   , Smessaert Jacob
Published: August 2024

This thesis sets out to analyse how democratic praxis in grassroots agrifood collectives contributes to the fostering of sustainability transformations that take a critical stance towards capitalism and the state. I analyse whether and how collectives develop alternative social and political forms that are neither based on, nor reproduce, statist and capitalist practices, norms, and institutions, as well as how they unsettle and challenge these structures through their democratic praxis. For this, I draw on a conceptualisation of democratic praxis as the diversity of political practices that contribute to an infinite, collective, continuous, and practical interrogation on how to live together based on the presupposition of equality and the generation of autonomy.

The different chapters of the thesis demonstrate the broad diversity of democratic praxis in grassroots agrifood collectives. They show that doing democracy in these collectives is based on a diversity of institutions, operational practices and practices of (re)production in which not only humans but also a variety of other-than-human actors are involved. The collectives under scrutiny in this thesis developed mechanisms to redistribute power
and created new political relationships with other-than-human actors (based on reciprocity and responsibility rather than on extraction and exploitation). They were reflective about their political practices and the exclusions they performed, and they developed procedures as well as experimental practices to either become more inclusive or acknowledge and enforce the exclusions they deemed necessary. In addition, they (re)politicised the agrifood system and their relationships with human and other-than-human members, and acknowledged interdependencies and entanglements with a variety of lifeforms in their attempted construction of vibrant, more-than-human political communities. Finally, these collectives approached democratic praxis as a permanent tension and accepted that doing democracy, becoming-interdependent, and generating autonomy have no external foundation nor justification and, thus, require continuous collective experimentation. As such, the democratic praxis of grassroots agrifood collectives constitutes sustained attempts to do politics differently, to make concrete interventions in the social-ecological coordinates of contemporary capitalist societies, and to explore the enactment of a variety of possible collective futures and lifeworlds.

Authors: Shofia Aina Rahmani  , M. Maulana  , I. Isrokatun
Published: August 2024

Students' understanding of mathematical concepts is still relatively low, especially in data material. One of them is caused by the learning process which is still student-centered. So this research aims to find out how to increase student's ability to understand mathematical concepts using tournament-based learning with the help of panta media. This type of research is quasi-experimental with a nonequivalent control group research design. The population used was class V students in North Sumedang District with research samples from class V at SDN Sindang II as the experimental class and SDN Jatihurip as the control class. The instrument used is a test of the ability to understand mathematical concepts with description questions. The analysis technique in this research is the mean difference test (paired sample t-test and independent sample t-test) which has been tested for normality and homogeneity. To determine the increase in students' mathematical abilities, the N-Gain test was carried out. The two classes were given different treatments, namely the experimental class with tournament-based learning assisted by panta media and the control class with conventional learning. The increase in students' ability to understand mathematical concepts can be seen from the average N-Gain results in the experimental class of 0.6500 in the moderate improvement category and in the control class of 0.2591 which is classified as low improvement. The two classes have significant differences in their ability to understand mathematical concepts. It was concluded that tournament-based learning with the help of panta media can improve students' understanding of mathematical concepts.

Most students consider mathematics difficult, because it is abstract. To respond to this, teachers can use ethnomathematics in learning mathematics so that mathematics is easy to understand. One of the ethnomathematics objects that can be used is market snacks. Market snacks are traditional foods that are often sold in crowded places such as markets. This study aims to analyze the geometrical concepts that exist in various forms of market snacks in Kudus. This research uses a type of qualitative research with an ethnographic approach. Data collection used semi-structural interviews with 3 market snack sellers, literature studies, and documentation. The results of the study found that there are geometric concepts in market snacks. Triangular, rectangular, and circular shapes are found, while for spatial shapes, rectangular pyramids, blocks, spheres, triangular prisms, and tubes are found. The research results can be used as an alternative source of learning mathematics, especially in geometry material.

Perceptions versus Reality: Personal Narrative Persuasion in Anonymous Cross-Partisan Interactions on a Mobile Chat Platform
Authors: Jordan Diana
Published: August 2024

Narrative persuasion techniques have effectively altered attitudes within the contexts of canvassing, video presentations, and survey experiments. This study examines the efficacy of personal narratives, in comparison to evidence-based persuasive techniques, in online conversations among ordinary citizens. It investigates surveys and text from 1,169 United States citizens engaged in cross-partisan conversations about divisive political issues on DiscussIt, an innovative mobile chat platform. Results reveal that receiving personal narratives in online cross-partisan interactions significantly predicts participants' perceptions that their chat partner had a persuasive influence on their opinions. In contrast, evidence-based messaging significantly predicts the opposite. However, neither technique predicted observable attitude change in participants' political attitudes. This perception-reality disconnect highlights the need to better understand the avenues through which narrative-driven messages wield influence in political persuasion and prompts us to examine whether persuasion primarily manifests through perceptions rather than tangible attitude change, especially in dialogue across party lines.
Not all causal effects are created equal: selecting pathway cases for in-depth analysis using causal forests
Authors: Surdea Vlad
Published: August 2024

Providing complex answers to causal questions requires both cross-case evidence for the existence of a causal effect and within-case evidence for the mechanisms through which this effect propagates. The former requires a causal identification strategy, while the latter is more amenable to qualitative investigation using methods tailored to mechanistic analysis, such as process tracing. However, once a cross-case causal effect has been estimated, there is little guidance on how to select a case in which to trace the mechanism. After reviewing the limitations of the available algorithms , I present a novel case selection method that uses causal forests to recover granular effects for each case in the sample, and show how this approach can be used to select pathway cases in a manner consistent with their stated goal. I then briefly discuss how this framework can be extended to other types of cases, including typical and deviant cases.
