Authors: Sweetman Melissa M. , Giles Amanda K.
Published: May 2023

Importance: Results of this study are helpful for the development of new faculty members who may have been trained as clinicians but not necessarily as academicians.

Objective: To determine occupational therapy faculty perceptions of their preparation for a teaching role, evaluate professional development activities in which educators currently engage, and identify teaching and learning topics most needed in future training activities.

Design: Quantitative, descriptive survey.

Setting: Educational institutions across the United States.

Participants: Occupational therapy and occupational therapy assistant faculty (N = 449).

Outcomes and Measures: A survey was created, pilot tested, and distributed. Questions were related to respondents’ institutional requirements and support for faculty development, developmental activities in which respondents participated, comfort levels with select teaching responsibilities, and topics of interest for additional development.

Results: Results show that training related to teaching and instructional design is not required but is highly encouraged at most educational institutions. Although most institutions do provide financial support for development opportunities outside of the institution, informal meetings are the predominant development activities both offered and used by faculty. Respondents cited learning how to develop test questions, designing course assignments, and learning about teaching methods and techniques as topics about which they would most like to gain more knowledge.

Conclusions and Relevance: These results inform a meaningful and necessary plan to train new occupational therapy faculty members as academicians and to ensure continuing development of experienced faculty for optimal performance and retention.

What This Article Adds: This report provides faculty and administrators with a starting point for the provision of faculty development content that has the potential not only to improve teaching skills but also to increase faculty self-confidence and retention.

Published: May 2023

Transportation through sea transportation modes can be carried out to the side of the port and transported further by trucking mode or by other transportation systems, namely using a conveyor belt or belt conveyor that will deliver the cargo directly to the stockpile field or other places. A belt conveyor is a device that delivers bulk cargo to the destination of shelter or stacking. Transportation of one of the loads, namely coal using a conveyor belt by unloading the cargo using a crane to insert the cargo into the conveyor belt. Based on literature studies and field observations from research related to belt conveyor operations, supporting factors for the smooth operation of conveyors include belt width on the belt conveyor, type of idler, angular accuracy, gearbox speed, and density of each load. In addition, periodic maintenance and maintenance factors can reduce the risk of obstacles related to belt conveyor operations, including belts that suddenly jam, and loss of cargo (losses) causing losses and fines. Periodic maintenance and maintenance should be outlined in the Planning Maintenance System which must be complied with and needs to be supervised for implementation. Periodic audits are important to carry out the fulfillment of procedures in the field and checks on the condition of the equipment to minimize losses due to damaged equipment.

Using a deep neural network to detect methane point sources and quantify emissions from PRISMA hyperspectral satellite images

Published: May 2023

Abstract. Anthropogenic emissions of methane (CH4) have made a considerable contribution towards the Earth's changing radiative budget since pre-industrial times. This is because large amounts of methane are emitted from human activities, and the global warming potential of methane is
high. The majority of anthropogenic fossil methane emissions to the
atmosphere originate from a large number of small (point) sources. Thus,
detection and accurate, rapid quantification of such emissions are vital to
enable the reduction of emissions to help mitigate future climate change.
There exist a number of instruments on satellites that measure radiation at
methane-absorbing wavelengths, which have sufficiently high spatial
resolution that can be used for detecting plumes of highly spatially
localised methane “point sources” (areas on the order of m2 to
km2). Searching for methane plumes in methane-sensitive satellite
images using classical methods, such as thresholding and clustering, can be
useful but is time-consuming and often involves empirical decisions. Here,
we develop a deep neural network to identify and quantify methane point
source emissions from hyperspectral imagery from the PRecursore
IperSpettrale della Missione Applicativa (PRISMA) satellite with 30 m
spatial resolution. The moderately high spectral and spatial resolution, as
well as considerable global coverage and free access to data, makes PRISMA a
good candidate for methane plume detection. The neural network was trained
with simulated synthetic methane plumes generated with the large eddy
simulation extension of the Weather Research and Forecasting model
(WRF-LES), which we embedded into PRISMA images. The deep neural network was successful at locating plumes with a F1 score, precision, and recall of 0.95, 0.96, and 0.92, respectively, and was able to quantify emission rates with a mean error of 24 %. The neural network was furthermore able to locate several plumes in real-world images. We have thus demonstrated that our method can be effective in locating and quantifying methane point source emissions in near-real time from 30 m resolution satellite data, which can aid us in mitigating future climate change.

Abstract. The reconstruction of past sea-ice distribution in the Southern Ocean is crucial for an improved understanding of ice–ocean–atmosphere feedbacks and the evaluation of Earth system and Antarctic ice sheet models. The Antarctic Peninsula (AP) has been experiencing a warming since the start of regular monitoring of the atmospheric temperature in the 1950s. The associated decrease in sea-ice cover contrasts the trend of growing sea-ice extent in East Antarctica. To reveal the long-term sea-ice history at the northern Antarctic Peninsula (NAP) under changing climate conditions, we examined a marine sediment core from the eastern basin of the Bransfield Strait covering the last Deglacial and the Holocene. For sea-ice reconstructions, we focused on the specific sea-ice biomarker lipid IPSO25, a highly branched isoprenoid (HBI), and sea-ice diatoms, whereas a phytoplankton-derived HBI triene (C25:3) and warmer open-ocean diatom assemblages reflect predominantly ice-free conditions. We further reconstruct ocean temperatures using glycerol dialkyl glycerol tetraethers (GDGTs) and diatom assemblages and compare our sea-ice and temperature records with published marine sediment and ice core data. A maximum ice cover is observed during the Antarctic Cold Reversal 13 800–13 000 years before present (13.8–13 ka), while seasonally ice-free conditions permitting (summer) phytoplankton productivity are reconstructed for the late Deglacial and the Early Holocene from 13 to 8.3 ka. An overall decreasing sea-ice trend throughout the Middle Holocene coincides with summer ocean warming and increasing phytoplankton productivity. The Late Holocene is characterized by highly variable winter sea-ice concentrations and a sustained decline in the duration and/or concentration of spring sea ice. Overall diverging trends in GDGT-based TEX86L and RI-OH' subsurface ocean temperatures (SOTs) are found to be linked to opposing spring and summer insolation trends, respectively.
Robust weather-adaptive postprocessing using MOS random forests
Authors: Muschinski Thomas , Mayr Georg J. , Zeileis Achim , Simon Thorsten
Published: May 2023

Abstract. Physical numerical weather prediction models have biases and miscalibrations that can depend on the weather situation, which makes it difficult to postprocess them effectively using the traditional model output statistics (MOS) framework based on parametric regression models. Consequently, much recent work has focused on using flexible machine learning methods that are able to take additional weather-related predictors into account during postprocessing, beyond the forecast of the variable of interest only. Some of these methods have achieved impressive results, but they typically require significantly more training data than traditional MOS and are less straightforward to implement and interpret. We propose MOS random forests, a new postprocessing method that avoids these problems by fusing traditional MOS with a powerful ML method called random forests to estimate "weather-adapted" MOS coefficients from a set of predictors. Since the assumed parametric base model contains valuable prior knowledge, much smaller training data sizes are required to obtain skillful forecasts and model results are easy to interpret. MOS forests are straightforward to implement and typically work well, even with no or very little hyperparameter tuning. For the difficult task of postprocessing daily precipitation sums in complex terrain, MOS forests outperform reference machine learning methods at most of the stations considered. Additionally, they are highly robust to changes in the data size and work well even when less than a hundred observations are available for training.
IMEX_SfloW2D v2: a depth-averaged numerical flow model for volcanic gas-particle flows over complex topographies and water
Authors: de' Michieli Vitturi Mattia , Esposti Ongaro Tomaso , Engwell Samantha
Published: May 2023

Abstract. We present developments to the physical model and the open source numerical code IMEX_SfloW2D (de' Michieli Vitturi et al., Geosci. Mod. Devel., 2019). These developments consist of a generalization of the depth-averaged (shallow-water) fluid equations to describe a polydisperse fluid-solid mixture, including terms for sedimentation and entrainment, transport equations for solid particles of different sizes, transport equations for different components of the carrier phase, and an equation for temperature/energy. Of relevance for the simulation of volcanic mass flow, vaporization and entrainment of water are implemented in the new model. The model can be easily adapted to simulate a wide range of volcanic mass flows (pyroclastic avalanches, lahars, pyroclastic surges) and here we present its application to transient dilute pyroclastic density currents (PDCs). The numerical algorithm and the code have been improved to allow for simulation of sub- to supercritical regimes and to simplify the setting of initial and boundary conditions. The code is open-source. The results of synthetic numerical benchmarks demonstrate the robustness of the numerical code in simulating trans-critical flows interacting with the topography. Moreover, they highlight the importance of simulating transient in comparison to steady-state flows, and flows in 2D versus 1D. Finally, simulation of the Krakatau 1883 eruption demonstrates the capability of the numerical model to face a complex natural case involving the propagation of PDCs over the sea surface and across topographic obstacles, showing the relevance, at the large scale, of non-linear fluid dynamic features, such as hydraulic jumps and Van Karman vortexes to flow conditions such as velocity and runout.
Structural control of inherited salt structures during inversion of a domino basement-fault system from an analogue modelling approach
Authors: Ferrer Oriol , Carola Eloi , McClay Ken
Published: May 2023

Abstract. The geometries of inverted rift systems are different
depending on a large variety of factors that include, among others, the
presence of decoupling layers, the thickness of the pre- and syn-extension
successions, or structural inheritances. Our study focuses on the inversion
of an extensional domino-style basement-fault system with a pre-extension
salt layer using analogue models to understand the role of pre-existing
structural features during inversion. Models investigate how different
overburden and salt thicknesses, inherited extensional structures, and salt
distributions condition the evolution during inversion. The experimental
results show that models with thick salt can partially or totally preserve
the extensional ramp–syncline basin geometry independently of the overburden
thickness. In contrast, models with a thin salt layer result in a total
inversion of the ramp–syncline basins with the development of crestal
collapse grabens and extensional faults affecting the overburden. Inversion
also triggered the growth or reactivation of salt-related structures such as
primary weld reopening and/or obliteration, diapir rejuvenation, salt
thickening, or thrust emplacement. The use of analogue modelling allowed us
to address the processes that controlled the growth and evolution of these
structural elements during the inversion. Experimental results also provide
a template of different structural styles resulting from the positive
inversion of basins with a pre-extensional salt layer that can help
subsurface interpretation in areas with poor seismic imaging.

Los liberales del Trienio constitucional (1820-1823) en búsqueda de sus orígenes: una iconografía y su ascendencia europea al servicio de una mitología política
Authors: Le Guellec Maud
Published: May 2023

El Trienio constituyó un hito en la historia española: durante tres años, la monarquía pasó de ser absolutista a liberal, y las ideas del Cádiz de 1812 pudieron por fin ponerse en práctica. Pero el haber tomado el poder no suponía haber conquistado las mentalidades: entre los muchos desafíos con los que lidiaron los nuevos dirigentes figuraba el de implantarse en el panorama político de su tiempo. El presente artículo se propone explorar una de las estrategias de legitimación empleadas por los liberales para conseguirlo –la escenificación de la génesis de su ideología–, estudiando el repertorio iconográfico al que recurrieron. A través de estampas de distinta índole, veremos cómo se realzan los orígenes del Trienio. Y veremos cómo la retórica visual desplegada se inscribe en una tradición ampliamente europea.

The BBF system comprising of 65 m length, 1.50 m spacing, and different depths (150 - 250 mm) resulted in 29-35% and 14-15% increase in soybean crop yield over control in normal and above normal rainfall (rainfall > 1050 mm) and below normal rainfall condition (rainfall < 750 mm), respectively. Mole drainage (MD) comprising of mole drains of 85 mm size formed at 4 m drain spacing and at a depth of 500 mm with 65 m lateral length resulted in 51% increase in soybean grain yield over the control under normal and above normal rainfall conditions. Soybean grain yield increased by 66- 74% under the treatment comprising of BBF coupled with MD over the control in above normal rainfall condition. The grain yield increase under mole drainage coupled with BBF for below normal rainfall condition was non-significant over the treatments comprising of BBFs only. The benefit-cost ratio for soybean crop cultivation using BBF, MD, BBF coupled with MD and conventional systems were found to be 1.65, 1.99, 2.03, and 0.98, respectively. The payback period of mole drainage technology was found to be less than 2 years. The effect of mole drainage on subsequent wheat crop recorded 11-12% increase in yield over the control. Field study revealed that BBF and BBF coupled with MD systems are technically feasible and economically viable for effective drainage of Vertisols.

За результатами проведеного дослідження визначено особливості військових цінностей у військовослужбовців-учасників бойових дій, у яких спостерігаються посттравматичні стресові реакції. У дослідженні прийняли участь військовослужбовці-учасники бойових дій, яких було поділено на дві групи: військовослужбовці, які мають ознаки посттравматичних стресових реакцій – 61 особа; та військовослужбовці, які не мають виражених посттравматичних стресових реакцій – 277 осіб. Вік учасників дослідження від 20 до 55 років.

Визначено, що військові цінності не дозволяють надійно передбачити посттравматичні стресові реакції у військовослужбовців-учасників бойових дій, проте не можна нехтувати їх роллю у регулюванні взаємин військовослужбовців, які мають ознаки посттравматичних стресових реакцій.

У військовослужбовців, які мають ознаки посттравматичного реагування, в ієрархії цінностей є виражена векторність від тріади сміливості, як уявлення про гідне поводження військовослужбовця, до тріади усвідомлення власної нестачі сил для здійснення протидії, власної ненадійності для оточуючих. Психологічна травматизація значно вплинула на структуру військових цінностей військовослужбовців, зробивши їх ненадійною ланкою військової команди. Так, їх структура цінностей, яка має регулювати професійну діяльність, відбиває їх зосередженість на травматичних аспектах – для них реалізація сміливості є виходом за межі уявлень про власні можливості, а професійність асоціюється із здоланням труднощів. Вони вважають, що пережитий досвід дозволяє їм керуватися власними уявленнями про обов’язок перед військовою командою, діяти на свій розсуд.

Відсутність в структурі цінностей військовослужбовців з ознаками посттравматичних стресових реакцій на відміну від військовослужбовців, у яких після участі в бойових діях збережене психічне здоров’я, фактору, що дозволяє бути відповідним змінам, вірогідно також посилює травматичний ефект дії бойових стресорів.

O trabalho monográfico intitulado “A importância de atividades lúdicas e experimentais no ensino de física do Centro Educacional de Jovens e Adultos (CEJA)”, apresenta como objeto de estudo analisar o papel do educador no desenvolvimento da aprendizagem a partir do uso experimental, bem como contribuir para melhoria da qualidade do ensino de ciências no Centro Educacional de Jovens e Adultos (CEJA), localizado na Rua Antero Torreão s/n, São José dos Cordeiros - Paraíba, é uma escola destinada apenas ao ensino da modalidade EJA, para tanto possui uma sede própria e funciona no turno vespertino e noturno. No que se refere a metodologia empregada neste estudo, pode-se dizer que trata-se este estudo de pesquisa descritiva, explicativa, ao qual contou com a participação dos alunos do 1º, 2º e 3º ano da referida escola. Para a pesquisa, foi utilizado como instrumento de análise um questionário com perguntas objetivas e subjetivas. O formulário foi distribuído aos alunos, onde foi explicado como deveria ser preenchido. Após a coleta de dados, foi possível observar que os alunos aceitam a ideia e o fato de que o uso de experimentos em sala de aula contribuem bastante para o seu aprendizado, além de tornar as aulas mais dinâmicas e participativas, permitindo uma melhor interação entre aluno e professor e consequentemente, despertando um maior interesse do aluno pela aula. Contudo, conclui-se que, o professor pode fazer uso de materiais de baixo custo para fazer determinadas experiências em sala de aula, sem que possa haver a necessidade de se ter um laboratório específico, ou gastos maiores, tendo em vista que os materiais de baixo custo são simples, baratos e de fácil aquisição. Assim sendo, possibilitam que os alunos possam compreender que a ciência encontrase em todos os lugares, principalmente em nosso cotidiano.

《貝爾武夫》：「好客」與「不好客」背後的動機
Authors: 應芳瑜 應芳瑜
Published: May 2023

《貝爾武夫》的盛宴一方面表現出「好客」，另一方面則表現出「不好客」。貝爾武夫的故事發生在西元六世紀斯堪地納維亞半島。當時居住在丹麥的丹麥人和居住在蓋特蘭的蓋次人越過名為卡特加特（丹麥語）的海峽進行互訪活動。本研究引用相關資料—德希達的形而上學之差異論、馬塞爾莫斯的送禮理論，一些聖經故事和怪物研究來探討《貝爾武夫》文本之中的本地人與外國人之間以及人類與怪物之間的界限。本文旨在闡明主方的「好客」和「不好客」背後的動機。《貝爾武夫》的盛宴表面上是「好客」，其實是基於互利互惠；「不好客」的行動亦是考量部落利益而採取的策略。主方對客方的「不好客」可能會引起客方的嫉妒，而嫉妒是萬惡之源之一。蓋次部落對噴火龍表現出「不好客」的立場與行為，同樣地，丹麥部落對格倫德爾也表現出「不好客」的立場與行為。在《貝爾武夫》文本之中，噴火龍和格倫德爾皆為異族，語言和外表明顯與人類不同，兩者皆被視為怪物；然而，蓋次人和丹麥人是互相來往、互通有無、文化交流、而且語言相通，雙方互相表現「好客」的立場與行為；但是，「好客」背後的動機不單純只是友誼，還有權力、財富、榮譽、地位、同盟抗敵之考量。本文主張「好客」盛行於在同質文化，其手段較為複雜，較容易顯現於人類社會之中，「好客」的程度取決於共同利益的程度，而「不好客」則是普遍存在於人類社會和怪物社會。

 

Feasts in Beowulf show hospitality on the one hand and inhospitality on the other hand. The story in Beowulf is set in pagan Scandinavia in the sixth century. At that time the Danes in Denmark and the Geats in Geatland crossed the strait named Kattegat (in Danish) to visit each other. This study draws on relevant resources—Derrida’s metaphysics of différance, Marcel Mauss’s theory of gift giving, and some biblical stories to examine the boundaries between locals and foreigners and between humans and monster-like creatures in Beowulf. Banquets in Beowulf are a sign of hospitality on the surface. However, beneath the surface it has been prepared owing to the Danes’ reliance on foreign support for their attempt to defeat a powerful monster-like enemy. The article aims to clarify the hosts’ motivations behind their hospitality and inhospitality. Banquets in Beowulf show hospitality on the surface, but it is based on mutual interests. In a similar sense, inhospitality is a strategy that takes tribal interests into account. Hosts’ inhospitality to visitors may cause jealousy which is one of the sources of evils. The Geats show inhospitality to the dragon as the Danes do it to Grendel. This article argues that hospitality tends to prevail in homogeneous cultures, and its means are more complex, and it is more common to exist in complicated human society. The degree of hospitality depends on the degree of mutual interests, while inhospitality is more likely to exist in both human society and monster’s society.
