Published: February 2022

Murabaha financing is a superior product in Islamic banking which is included in buying and selling contracts. After experiencing the development and modification of murabahah financing, it is now better known as murabahah bil wakalah. The purpose of this study is to find out the problems that exist in the murabahah bil wakalah contract, namely the occurrence of side streaming actions. This study uses a qualitative method with a literature study where data are taken from sources derived from literature such as books, articles, and other sources. Murabahah bil wakalah contract is a sale and purchase contract in which the Islamic bank gives power or represents to the customer to purchase the object of self-financing from the supplier. With the power granted this creates some problems that can damage or invalidate the contract, such as side streaming actions. Side streaming is an act of using funds that is not in accordance with the contract,  so this action is considered a form of deviation and includes a fake contract. Customers tend to be more flexible in buying the desired goods, such as on behalf of the buyer from the supplier, not on behalf of the bank. Other side streaming actions can be in the form of price differences that have been agreed upon, and cause non-performing financing and a decrease in the collectability of Islamic banks.Keywords: Murabahah bil Wakalah, Side Streaming, Islamic Banking

OPTIMALISASI FUNGSI DAN KEDUDUKAN BANK SYARIAH DALAM UPAYA MEWUJUDKAN INTEGRASI ISLAMIC SOCIAL FINANCE DAN ISLAMIC COMMERICIAL FINANCE
Authors: Fauziah Salma
Published: February 2022

Bank syariah dalam menjalankan kegiatan usahanya tidak hanya berfokus pada aspek komersial atau mencari keuntungan semata, akan tetapi juga diimbangi dengan fungsi sosial sebagaimana telah diamanatkan dalam Undang-Undang Perbankan Syariah yaitu sebagai penghimpun dan penyalur dana zakat, infaq, sedekah dan wakaf (ziswaf). Hal ini dilakukan juga sebagai upaya mengintegrasikan keuangan komersial dan sosial Islam. Dalam praktiknya, banyak bank syariah yang telah menjalankan fungsi sosialnya, namun sayangnya belum dapat dilakukan secara optimal. Padahal Indonesia sendiri memiliki potensi yang sangat besar dalam hal pengelolaan dana ziswaf. Metode pendekatan yang digunakan dalam penulisan ini bersifat yuridis normatif, yaitu penelitian yang menggunakan data sekunder yang terdiri dari bahan hukum sekunder maupun studi kepustakaan yang kemudian dianalisis secara yuridis kualitatif. Untuk spesifikasi penelitian tulisan ini bersifat deksriptif analitis. Hasil penelitian menunjukkan bahwa bank syariah pada dasarnya memiliki fungsi dan kedudukan yang bersifat sosial dalam mengumpulkan dana ziswaf. Pelaksanaan fungsi sosial tidak hanya terkait dengan ketentuan yang ada di dalam Undang-Undang Perbankan Syariah, akan tetapi juga tunduk pada peraturan mengenai zakat dan wakaf. Dalam upaya mengoptimalkan fungsi dan kedudukan sosialnya, bank syariah dapat melakukan beberapa strategi seperti penguatan regulasi dan pengawasan, kolaborasi dengan lembaga pengelola ziswaf, serta menciptakan produk yang inovatif.

Buying and Selling the Poor
Authors: O'Sullivan Siobhan , Considine Mark , McGann Michael
Published: February 2022

Buying and Selling the Poor ventures behind the scenes of the multibillion-dollar welfare-to-work system, offering new insights into how Australia responds to unemployment and disadvantage. As the authors tell the story of four local employment offices, they paint a vivid picture of a critically important social service which many people are aware of but which few properly understand. They also reveal the wider impacts that processes of marketisation and welfare reform have had on these frontline services over decades, and how the work of frontline staff and service providers has been transformed. Buying and Selling the Poor looks closely at how these services operate, why some succeed where others fail, and what can be learned from the stories of staff and clients who have navigated the system. Three decades into this market experiment, how well are we doing in supporting our most vulnerable citizens to get back to work?
Epistemología aplicada a la medicina
Authors: Gensollen Mendoza Mario
Published: February 2022

A lo largo de la historia, en diversas ocasiones la práctica médica hizo mucho daño a la humanidad. Esto ha generado varias formas de desconfianza hacia la medicina, que se conocen como “nihilismo médico”. Mi objetivo en este artículo es examinar diversas versiones de esta tesis. Defiendo que, aunque algunos nihilismos médicos son razonables, una posición nihilista mucho más robusta resulta problemática. Para ello, comienzo distinguiendo una amplia variedad de posibles posiciones nihilistas. A continuación, aíslo aquellas que, por diversas razones, resultan tanto contenciosas como interesantes desde un punto de vista filosófico. En un momento posterior, presento y evalúo varias críticas comunes que se han realizado a un aspecto de la medicina actual, que involucra tanto consideraciones metodológicas de la investigación biomédica contemporánea como implicaciones epistemológicas de su práctica institucionalizada. Concluyo extrayendo algunas lecciones de dicha evaluación.

La rotación de los estudiantes de medicina por servicios de salud es una oportunidad para mostrarles cómo se aplican valores, habilidades y criterios en el día a día. En general, existe una cierta disociación entre lo que el estudiante considera estándar de calidad y lo que observa en los servicios asistenciales, presionados por una falta de tiempo y recursos crónicos.El presente artículo explora estrategias para que este salto de la teoría a la práctica sea una experiencia positiva para el estudiante. Y, así, evitar el peligro de instaurar un currículo oculto inaparente que prioriza sobrevivir, en un territorio hostil, a la aplicación de habilidades y a la reflexión crítica de cada paciente. Enseñar a reflexionar en un contexto de presión asistencial es una de las grandes aportaciones que puede realizar las prácticas tuteladas en centros asistenciales, sobre todo de Atención Primaria de Salud.

A new method of feed evaluation in milk production
Authors: Kulyk Mikhailo , Skoromna Oksana , Honchar Lesya , Zelinska Iryna
Published: February 2022

Purpose. Development of a new method for estimating 1 kg of feed dry matter in milk production. Methods. The standard methods for evaluating feed based on the indicators of crude protein, fat, sugars, crude fiber, feed units, gross, metabolic, digestible and net energy of lactation and others. Modern methods of feed evaluation are based on metabolic energy, but they have some controversies. Whereas the method on the base of milk production is quite different. Milk protein synthesis occurs only from the amino acids of feed protein and bacterial protein of rumen biomass, in the synthesis of which non-protein feed ingredients are used. When converting the amino acids of crude feed protein into any type of energy, the reverse synthesis of amino acids from energy does not occur, so evaluation of feed in milk production on the base of the crude protein content in feed is biochemically justified. Results. The essence of the new suggested method of feed evaluation in milk production of 1 kg of feed dry matter is expressed by the product of 3.1 MJ of energy of 1 liter of milk on the ratio of gross energy of crude feed protein to gross energy of crude diet (%) with hemicellulose in the amount of 1/2 of the estimated feed, as this hemicellulose is not broken down in the rumen, because it is structurally combined with the cellulose of crude fiber of the evaluated feed. Typical rations for cows with a content of 17.0 were taken for evaluation; 23.0; 26.0; 30.0 and 32.0% of crude fiber and the same rations with the inclusion of hemicellulose in the amount of 1/2 of the content of SC in the evaluated feed and obtaining the gross energy of the total amount of structural carbohydrates. Conclusions. The essence of the suggested method of feed evaluation in milk production of 1 kg of feed dry matter lies in taking into account hemicellulose in calculation as this hemicellulose is not broken down in the rumen because it is combined with cellulose of the raw fiber of the evaluated feed. The confirming factor of validity of the new method of estimation in milk production of 1 kg of feed dry matter is the cost of crude protein for the formation of 1 liter of milk. Crude protein is found in the structure of cellulose and hemicellulose fibers. The high level of utilization of crude protein for milk protein synthesis is characteristic of concentrated feeds when used in high-yielding cows feeding.
Meteotsunamis in Japan associated with the Tonga Eruption in January 2022
Authors: KATAOKA RYUHO , Winn Stephen , Touber Emile
Published: February 2022

Large-amplitude meteotsunamis were observed in many areas in Japan, following the arrival of barometric Lamb waves emitted by an underwater volcanic eruption of Hunga Tonga-Hunga Ha‘apai in January 2022. We modeled the power spectra of the tidal level data obtained from 12 tide stations of the Geospatial Information Authority of Japan, based on a single transfer function which converts the barometric pressure pulse spectra into the meteotsunami spectra. The pressure pulse spectra are obtained from the ensemble average of ~1500 Soratena weather sensors of Weathernews Inc. distributed over Japan. The observed meteotsunami spectra can be characterized by the enhanced seiche eigenmodes at each station excited by the mesoscale pressure pulse, which contributes for accumulating the necessary knowledge to understand the potential dangers in various different areas over Japan.
Per- and poly-fluoroalkyl substances (PFAS) in river discharge: modeling loads upstream and downstream of a PFAS manufacturing plant in the Cape Fear watershed, North Carolina.

Published: February 2022

The Cape Fear River is an important source of drinking water in North Carolina, and many drinking water intakes in the watershed are affected by per- and polyfluoroalkyl substances (PFAS). We quantified PFAS concentrations and loads in river water upstream and downstream of a PFAS manufacturing plant that has been producing PFAS since 1980. River samples collected from September 2018 to February 2021 were analyzed for 13 PFAS at the upstream station and 43-57 PFAS downstream near Wilmington. Frequent PFAS sampling (daily to weekly) was conducted close to gauging stations (critical to load estimation), and near major drinking water intakes (relevant to human exposure). Perfluoroalkyl acids dominated upstream while fluoroethers associated with the plant made up about 47% on average of the detected PFAS downstream. Near Wilmington, Σ43PFAS concentration averaged 143 ng/L (range was 40-377) and Σ43PFAS load averaged 3,440 g/day (range was 459-17,300), with 17-88% from the PFAS plant. LOADEST was a useful tool in quantifying individual and total quantified PFAS loads downstream, however, its use was limited at the upstream station where PFAS levels in the river were affected by variable inputs from a wastewater treatment plant. Long-term monitoring of PFAS concentrations is warranted, especially at the downstream station. Results suggest a slight downward trend in PFAS levels downstream, as indicated by a decrease in flow-weighted mean concentrations and the best-fitting LOADEST model. However, despite the cessation of PFAS process wastewater discharge from the plant in November 2017, and the phase-out of PFOS and PFOA in North America, both fluoroethers and legacy PFAS continue to reach the river in significant quantities, reflecting groundwater discharge to the river and other continuing inputs. Persistence of PFAS in surface water and drinking water supply suggests that up to 1.5 million people in the Cape Fear watershed might be exposed.
Pursuing Whiteness in the Colonies. Private Memories from the Congo Freestate and German East Africa (1884–1914)
Authors: Natermann Diana Miryong
Published: February 2022

Pursuing Whiteness in the Colonies offers a new comprehension of colonial history from below by taking remnants of individual agencies from a whiteness studies perspective. It highlights the experiences and perceptions of colonisers and how they portrayed and re-interpreted their identities in Africa. The transcolonial approach is based on egodocuments from Belgian, German and Swedish men and women who migrated to Central Africa for reasons like a love for adventure, social betterment, new gender roles, or the conviction that colonising was their patriotic duty. The author presents how colonisers constructed their whiteness in relation to the subalterns in everyday situations connected to friendship, animals, gender and food. White culture was often practiced to maintain the idea(l) of European supremacy, for example by upholding white dining cultures. The welcoming notion of ‘breaking bread’ was replaced by a dining culture that reinforced white identity and segregated white from non-white people. By combining colonial history with whiteness studies in an African setting the author provides a different understanding of imperial realities as they were experienced by colonisers in situ.

In recent years, claims for damages for deliberately or negligently inflicted psychiatric illness have succeeded against employers in jurisdictions outside Malaysia. In the case of Mount Isa Mines v Pusey, the court decided that an employer’s duty of care towards the employees is not limited to cases of physical injury but also extended to cases of psychiatric injury. In order to claim damages for psychiatric injury, the law of torts requires the plaintiff to prove two elements: namely, reasonable foreseeability and proximity. This paper examines on the two elements as required under the law in the context of psychiatric illness in the workplace. The paper analyses cases from the UK, Malaysia and Australia, elaborating on how an employee can successfully bring an action against his/her employer for his/her psychiatric illness suffered at the workplace. The author employs doctrinal analysis from primary and secondary legal sources in arriving at the solutions to the above problem. This paper will significantly contribute to the existing literature by discussing the challenges faced by an employee in proving the conditions required by the law and its solutions to ensure that employee who suffered psychiatric illness or injury in the workplace has a redress under the law of negligence. This paper also considers the scenario from an Islamic perspective in order to shed light on the seriousness of the welfare of employee guaranteed by the religion. Having shown how divine revelation makes it incumbent on an employer to honour and respect his worker, and treat him in kindness, it will be further shown how two Court of Appeal decisions have paved the way to find employers negligent for causing distress to their employees’ mental health. This paper, thus illustrates yet another fine example of harmonisation between the two systems of law, that can come together to achieve the same end.

Perletakan instalasi kelistrikan seperti perkabelan dalam sebuah lintas kereta api bisanya di tempatkan di bagian sub balas, hal demikian menjadikan maintenance instalasi tersebut menjadi sulit. Tidak hanya itu instalasi awal memerlukan pembongkaran struktur atas jalan rel seperti balas, bantalan dan rel. Untuk mempermudah kegiatan instalasi dan maintenance instalasi perkabelan maka direncanakan sebuah bantalan kereta api yang memiliki lubang (hollow) sebagai tempat sirkulasinya. Seperti yang diketahui jenis bantalan kereta api yang banyak digunakan di Indonesia adalah bantalan kereta api dengan jenis bantalan beton. Benda uji bantalan beton digunakan model N-67 produksi PT. WIKA dengan lebar spoor 1067 mm. Lubang direncanakan memiliki bentuk penampang lingkaran dengan diameter 2 inch, geometri lubang pada bantalan adalah horizontal searah panjang bantalan. Analisa perilaku bantalan beton berlubang menggunakan software berbasis finite element. Benda uji dimodelkan ke dalam software dengan menginputkan dimensi serta properti material seperti pada penelitian (Fistcar, 2021) material kuat tekan beton fc’ 52 Mpa dan kuat tarik baja fy 1400 Mpa.
