Published: April 2022

An earthquake disaster is an event that causes various damage and loss of life. This study aims to determine the vulnerability of earthquake hazards in Bengkaung Village, West Lombok Regency. The method used in this research is the geomagnetic method. The results of this: study indicates the value of the magnetic field anomaly in the range of -1100 nT-1500 nT. 2D modeling with 4 paths shows that the study area is dominated by 5 rock layers with a susceptibility range between (0.013 - 6.21)×10^(-3) in SI, which consists of sandstone, clay, fractured andesite lava, fresh andesite lava. and granite. The highest vulnerability to earthquake hazards is in the southern part of Bengkaung Village, due to the presence of a cohesive soil type (like clay) on the surface of the study area, coupled with the presence of intrusions and faults. Meanwhile, the western part of Bengkaung Village and the northern part of the Bengkaung area have a relatively smaller earthquake hazard vulnerability than the southern part. This is because the western and northern parts have the main layer of non-cohesive soil (sandstone) which has high shear strength and becomes a damper in wave propagation when an earthquake occurs

Bengkulu city is facing groundwater problems where some of the groundwater is brackish. The study aimed to determine the structure of the subsurface layer through the propagation velocity of secondary wave (Vs) in a layer of porous medium in estimating the potential for groundwater. This research supported by resistivity data ​​and will be validated based on the depth of the well. MASW data was processed using WinMASW Professional 5.0 software to obtain a 1D profile of the Vs value, and Res2dinv software was used to obtain a 2D cross-section of the resistivity value. The results showed a decrease in the value of Vs in the porous medium layer from 133 to 358 m/s in the first path, and from 149 to 314 m/s for the second path. The decrease in the value of Vs is in the range of groundwater potential which is close to the depth of the resident's well, with the type of porous medium layer being sands and intact clays. The subsurface profile from the Vs measurement shows a good agreement with the resistivity value profile from the Geoelectric method. So, secondary wave propagation can be used in determining groundwater potential for a depth of < 10 m

Objective: To reduce unnecessary requests for Serum Thyroid stimulating hormone (TSH) levels in a hospital setting using targeted interventions. Study Design: Interventional study. Setting: Najran Armed Forces Hospital (NAFH), Saudi Arabia. Period: January 2019 to June 2020. Material & Methods: Sampling technique was non probability convenient sampling and included all the TSH requests received in the laboratory. The tests were categorized into three categories e.g., repeated requests within one month, requests as routine investigation and requests not related to diagnosis. The interventions made included the initiation of hospital guidelines, resolving the limitations of Laboratory information system (LIS) and increasing awareness of physicians. The effectiveness of interventions was calculated by measuring the number of unnecessary requests out of total number of TSH requests. The comparison was made between problem identification phase and post implementation phase. Results: The analysis of data showed a reduction in the routine unnecessary TSH requests by almost 11%. During the first half of 2019(Jan -July) total number of TSH tests were 5713 with 3427 (60%) unnecessary requests. After initiation and implementation of interventions the unnecessary requests reduced by 11% during Jan-July 2020. There were only 1857(49%) unnecessary requests out of total 3827 TSH tests. These results were statistically significant with p-value of less than 0.05. Conclusion: The application of appropriate interventions decreased the unnecessary requests of TSH. This reduction in turn reduced the wastage of the cost spent and the workload implied on staff for processing these unnecessary requests.
Menghormati Penulis dan Mengakui Pembaca: Pendekatan Rekonsiliatif Eric J. Douglass dalam Metode Reader’s Response
Authors: Gultom Junifrius
Published: April 2022

Abstract. Reader's response method is a method of reading text that is corrective to the structuralist method. To some degree, however, the meaning and its usage this method has some flaws. In general understanding, the use of the reader’s response method creates a desire to simply ignore the voices of the author of the text itself. As a result, this may potentially create a long gap between the writer and the reader in a work of finding the meaning. This paper aimed at explaining the conventions of language and of meaning that occur between writers and readers of the text, which is taken from Eric J Douglass' reconciliatory (stabilizing) approach to the author’s voice and reader activity. Reading and writing texts that embrace the side of readers and writers will bring about a more creative and rich meaning.Abstrak. Metode reader’s response adalah metode membaca teks yang korektif terhadap metode strukturalis. Namun, pengertian dan penggunaan dalam intensitas tertentu terhadap metode ini bukan berarti tidak mengandung beberapa masalah. Dalam pemahaman umum penggunaan metode reader’s response menimbulkan hasrat untuk begitu saja mengabaikan suara-suara penulis teks itu sendiri. Hal ini menjadikan gap yang panjang antara penulis dan pembaca di dalam sebuah perjalanan pencarian makna. Tulisan ini bertujuan untuk menjelaskan tentang konvensi bahasa dan makna yang terjadi di antara penulis serta pembaca teks yang ditempuh dengan pendekatan rekonsiliatif (stabilisasi) Eric J. Douglass terhadap suara penulis dan keaktifan pembaca. Pembacaan dan penulisan teks yang merangkul sisi pembaca dan penulis akan menghasilkan makna-makna yang lebih kreatif dan kaya.

Comparing Concerns—Some issues in organ and other donations
Authors: Strathern Marilyn
Published: April 2022

In an information society, where overload has become a problem, might anthropology’s comparative method find a new lease of life? This Lecture sets out to test the hunch that it might. A field ever more densely populated with information is that of organ and tissue donation, and the debates to which current practices give rise. Donation is only one of several modes of procurement, organs only one kind of body part that can be donated, and people offer comparisons just as commentators do. Perhaps here is an answer to the question of how to make a reasonable account out of a fraught and infinitely expandable nexus of public concerns. Is it possible to conserve the complexity of the issues while not letting the sheer quantity of information run away with  itself? Would following through the comparisons do the trick?
Equality, Inequality, and Exchange

Comments on: JOHN LIEP. A Papuan Plutocracy: Ranked Exchange on Rossel Island. Aarhus: Aarhus University Press, 2009. Pp. 376. ISBN: 978-87-7934-446-4
I mention that good ethnographies appear after the fact to be based on good fortune because John Liep looks for all the  world like one of those lucky types for whom this generalization holds true. Interested in economy and exchange, he found his way to Rossel Island, where people happen to operate what from some angles has to be seen as the most complex currency system in the world, one that turns on 34 different, ranked kinds of currency tokens, not counting state money,  and that features a welter of more or less unusual ways of moving those currencies around between people in transactions that shape marriages, funerals, and almost all of the other most important social institutions of Rossel Island life. As Liep  (p. xviii)1 puts matters, the complexity of the Rossel Island currency system makes it “an anthropological freak”—the kind of one-off limit case in the range of global variation that so often provides the materials for ethnographic success stories.  What better basis than fieldwork among the Rossel Islanders could there be, then, for making pointed interventions into disciplinary debates about the nature of exchange?

Here the Status Symbols Clash
Authors: Dutton Edward
Published: April 2022

This article aims to make an original contribution to the discussion of the dynamics of social status expression in Finland. Drawing upon fieldwork in Oulu and Kokkola, it will examine how a sample of Finnish people express and play for social status through the objects with which they decorate their homes. It suggests that Finnish social stratification may be undergoing a shift away from correlation with formal education towards identification with broader consumption patterns, especially amongst the young. However, it will also highlight social status-based differences in terms of both forms of expression and touch on how these reflect the evolution of Finnish social stratification and culture more broadly.

Keywords: Finland, social status, home, decoration
Methodological Aspects of Linguistic Expert Analysis of Communications on Sexual Topics with Minors
Authors: Kuznetsov V. O.
Published: April 2022

The article is devoted to the linguistic aspect of examinations on crimes against sexual integrity and sexual freedom. Based on the consistent legal, expert and linguistic analysis, the author observes the formation of a new type of forensic linguistic and comprehensive psychological and linguistic examinations, the object of which is the communication on sexual topics with minors in social networks and messengers. He also analyzes criminal law provisions covering crimes against a person’s sexual inviolability and sexual freedom. Subsequently, the expert concepts of “sexual acts”, “motivation” and “threat”, which are advisable to establish during the examination, are developed and brought into correlation with the linguistic knowledge. Finally, the author proposes methodological approaches to solving expert linguistic tasks when examining messages to the minors on sexual topics.

Вольтамперометрическое определение амоксициллина в твердой дозированной форме
Authors: Турусова Елена В. , Насакин Олег Евгеньевич
Published: April 2022

Разработана методика ускоренного определения амоксициллина (АМО) в твердой дозированной форме, основанная на предварительном экстракционном разделении компонентов препарата (клавулановой кислоты (КЛК) и АМО), с последующим титрованием его водного извлечения раствором фотогенерированного йода, полученного в результате облучения вспомогательного раствора, содержащего йодид калия, смесь сенсибилизаторов (эозината натрия:флуоресцеина:аурамина, взятых в молярном соотношении 1:1:1) и ацетатного буферного раствора (рН 5,6). В связи с тем, что содержание титранта в растворе контролировалось вольтамперометрическим методом (амперометрическое титрование с двумя поляризованными электродами), стабилизация тока в цепи амперометрической установки свидетельствовала о полноте протекания реакции, а, следовательно, позволяла регламентировать содержание АМО в лекарственной форме (ЛФ). Дальнейшее облучение раствора иризмерение времени генерации, необходимого для восполнения убыли титранта, также позволяло регламентировать содержание антибиотика в ЛФ. Экстракционное разделение компонентов позволяет извлечь из модельного раствора до 94,5 и 98,0 % КЛК и АМО соответственно. Установлено незначительное влияние лактулозы, присутствующей в ЛФ, нарфотогенерацию титранта. Найденное в ЛФ количество антибиотика входит в интервал, рекомендованный ОФС.1.4.2.0009.15, что свидетельствует о соответствии качества препарата стандартам GMP. Линейная зависимость аналитического сигнала от концентрации АМО наблюдается в интервале 2,0 – 15,0 мг для препарата «Аугментин, таблетки, покрытые пленочной оболочкой 875 мг + 125 мг». Рассчитанный предел обнаружения (ПО) и количественного определения (ПКО) для данного препарата составил 2,17 и 0,72 мг поризменению силы тока и времени генерации соответственно. Разработанная методика определения соответствует требованиям, изложенным в руководстве по валидации биоаналитических методов, проста в исполнении, не требует дорогостоящего оборудования, а, следовательно, может быть рекомендована для рутинного контроля содержания АМО в ЛФ в условиях любой контрольно-аналитической лаборатории.

Over 80 species of hypocrealean fungi are reported as pathogens of spiders and harvestmen. Among these fungi, the genus Gibellula is highly regarded as a specialised spider-killer that has never been reported to infect other arthropods. While more than 20 species of Gibellula
are known, few attempts to identify the infected spiders have been made despite the fact that the host specificity can help identify the fungal species. Here, we morphologically describe and illustrate eight new species of Gibellula and three new records from Thailand of known species
along with the multi-gene phylogeny that clearly showed the segregation among the proposed species. Examination of the Gibellula-infected spider hosts identified Oxyopidae, Uloboridae and, for the first time, the ant-mimicking genus Myrmarachne.

We mined published microarray data (5, 6) to understand in an unbiased fashion the most distinguishing transcriptional features of tumors from patients with basal or basal-like subtype breast cancer. We observed transcriptome-wide differential expression of cyclin N-terminal domain-containing 2, CNTD2, when comparing tumors of patients with basal-like breast cancer with that of other PAM50 molecular subtypes. CNTD2 mRNA was present at significantly higher quantities in the tumors of patients with basal-like breast cancer. Analysis of patient survival data revealed that CNTD2 primary tumor expression was correlated with overall survival in human breast cancer. Elevated CNTD2 expression appears to distinguish basal-like human breast cancer from the other molecular subtypes.

Although intelligence and personality traits have long been recognized as key predictors of students’ academic achievement, little is known about their longitudinal and reciprocal associations. Here, we charted the developmental interplay of intelligence, personality (Big Five) and academic achievement in 3,880 German secondary school students, who were assessed four times between the ages 11 and 14 years (i.e., in grade 5, 6, 7, and 8). We fitted random-intercept cross-lagged panel models (RI-CLPs) to investigate reciprocal within-person associations between (a) academic achievement and intelligence, (b) academic achievement and personality, as well as (c) intelligence and personality. The results revealed negative within-person associations between Conscientiousness and Extraversion assessed at the first wave of measurement and intelligence assessed at the second wave. None of the reciprocal personality-achievement associations attained statistical significance. Academic achievement and intelligence showed reciprocal within-person relations, with the strongest coefficients found for achievement longitudinally predicting intelligence. Our work contributes to developmental theorizing on interrelations between personality, intelligence, and academic achievement, as well as to within-person conceptualizations in personality research.

RESUME KESEIMBANGAN PASAR UANG DAN PASAR BARANG DALAM EKONOMI MAKRO ISLAM
Authors: Rahmi
Published: April 2022

Pasar barang merupakan pasar yang dimana tempat bertemunya penawaran dan permintaan atas sebuah barang atau jasa. Biasanya pasar barang ini disebut atau lebih dikenal dengan istilah sektor rill. Kurva IS merupakan sebuah kurva yang dapat menghubungkan antara suku bunga ( I atau r ) dengan pendapatan nasional (Y) yang menunjukkan titik tingkat keseimbangan pada pasar barang yang akan sellau berpatokan kepada pendapatan nasional pendekatan pengeluaran ( ependatur apporoah ) hanya saja yang membedakannya pada investasi. Pada system ekonomi Islam bunga tidak diberlakukan, sehingga keseimbangan di pasar barang pada ekonomi Islam ini sangat berbeda dengan keseimbangan pasar barang pada system ekonomi konvensional. Hal ini karena system bunga dihapuskan dan diganti dengan tingkat keuntungan yang diharapkan atau expected rate of profit(π). Investasi perusahaan dalam ekonomi Islam tergantung dari tingkat expected rate of profit atau keuntungan yang diharapkan (π) dan biaya atas asset yang kurang produktif atau dianggurkan (μ). Makin tinggi keuntungan yang diharapkan, dan makin besar biaya asset yang kurang produktif maka semakin besar investasi yang dilaksanakan dan sebaliknya.
Pembelajaran Bahasa Indonesia di Sekolah dalam Interaksi Lingkungan Masyarakat Multietnik

Published: April 2022

Bahasa dan lingkungan merupakan dua hal yang saling memengaruhi. Keragaman interaksi dalam lingkungan masyarakat Indonesia yang multietnik tidak selalu menjadi faktor penghambat dalam pembelajaran bahasa Indonesia, tetapi juga dapat memperkaya kosakata peserta didik yang sangat mendukung dalam materi sastra sebagai bentuk pembelajaran keterampilan berbahasa. Kesadaran masyarakat terkait pentingnya bersikap positif terhadap keragaman bahasa di lingkungan masyarakat tergolong baik dan akan terus dapat diupayakan melalui teks bacaan dalam pembelajaran bahasa Indonesia. Dengan pemahaman yang baik tentang interaksi lingkungan masyarakat multietnik dengan pembelajaran bahasa Indonesia, upaya mewujudkan kesatuan dan persatuan pun akan lebih mudah untuk direalisasikan di lingkungan masyarakat.

Ijtihad Ekonomi Ala Madura Era Pandemi

Published: April 2022

Paternalistik orang Madura sangat kental dalam kehidupan sehari-harinya dimana lebih memegang teguh petuah Tetua dan Ulama, setelah orang tuanya. Sebagaimana terpatri dalam pepatah Madura Bhuppa’ Bhabhu’ Guru Rato. Rato sebagai simbol negara menempati urutan terakhir. Tidak heran bila orang Madura terkesan cengkal (tidak patuh) Protokol Kesehatan karena ada nasehat Tetua dan Kiainya yang lebih ditaati. Relasi Kiai-Santri begitu melekat dalam karakter orang Madura. Hal ini juga berlaku dalam mempertahankan kehidupan ekonomi yang merosot tajam. Upaya-upaya yang dilakukannya berdasarkan arahan patronnya. Penerbitan Nomor Izin Berusaha (NIB) sangat membantu pelaku usaha perorangan yang selama ini tidak mendapatkan informasi yang memadai terutama selama pandemi. Komunitas UNK harus bersinergi dengan pihak UMKM, Dinas-dinas terkait dan organisasi kemasyarakatan.
Legenda Perseorangan
Authors: Nurqomah Resty
Published: April 2022

Legenda selaku salah satu jenis sastra lama yang memiliki ciri-ciri tersendiri. Hoykas dalam Djamaris (1990: 98) menganggap legenda selaku dongeng berdasarkan sejarah, suatu kejadian yang berhubungan dengan agama, orang-orang yang taat dengan ibadahnya ataupun orang-orang yang mengembangkan agama. Sehingga disimpulkan legenda adalah salah satu jenis sastra lama berbentuk prosa yang berisi unsur sejarah serta ditokohi oleh orang-orang yang taat beribadah dalam mengembangkan agamanya. Legenda Banjar tidak hanya berkaitan dengan masyarakat Banjar pada masa lalu, tetapi menunjukkan bahwa kebudayaan Banjar modern yang berkembang sekarang ini merupakan mata rantai kebudayaan yang tak terputus dengan kebudayaan Banjar masa lalu. Segala hal yang terungkap dalam legenda Banjar masih mempunyai relevansi dengan kehidupan masyarakat Banjar sekarang, bahkan yang akan datang. Legenda itu akan selalu mempunyai kedudukan dalam masyarakat masa lalu dan masyarakat sekarang. Hal ini Sejalan dengan pendapat Teeuw (1982: 10) menyatakan yang termasuk di dalam legenda, manusia Indonesia berusaha untuk mewujudkan hakikat dirinya sendiri hingga sekarang pun, untuk manusia modern, ciptaan itu tetap mempunyai nilai serta fungsi, asalkan ia bersedia berusaha untuk merebut maknanya selaku manusia modern. Perkembangan sastra daerah serta sastra Indonesia dapat mengambil nilai dari legenda. Untuk Kalimantan Selatan, karya dramawan Adjim Ariadi, Rudy karno, Burhanuddin Subli, dan Eman Hermansyah banyak mengadopsi sastra lisan Banjar dan unsur teater rakyat mamanda.
Retracing the threads: The importance of the Purity foundation for predicting culture war attitudes is measurement-contingent
Authors: Crone Damien , Laham Simon
Published: April 2022

The moral foundation of Purity is widely regarded as the most important moral concern underpinning people’s positions on divisive political issues (the Purity Dominance hypothesis). An influential source of evidence for this hypothesis is a study by Koleva et al. (2012) in which they used the Moral Foundations Questionnaire (MFQ) to predict people’s positions on a variety of “culture war” issues, finding that, among the five foundations posited by Moral Foundations Theory, Purity was frequently the most predictive of issue positions. In a study of N = 744 Australian undergraduate students, we present a replication and extension of Koleva et al. (2012), testing whether the Purity Dominance hypothesis is robust to alternative operationalizations and analytic approaches. Although successfully replicating the original pattern of findings using the same operationalization as Koleva et al., 2012 (the MFQ), we find that this Purity Dominance finding is not robust to two alternative operationalizations that are not subject to a substantial demographic confound with religious identification affecting the MFQ’s operationalization of Purity. The Purity Dominance finding is further undermined by adopting an alternative analytic approach (structural equation modeling) that accounts for the differential reliability of the different moral foundations. Taken together, these results suggest the need to reconsider the Purity Dominance hypothesis, and highlight the importance of testing hypotheses across multiple operationalizations and analytic approaches.
