Risk-Based Criticality Assessment for Smart Critical Infrastructures

Today, critical infrastructure is more interconnected, which allows more vulnerabilities in the case of disasters. In addition, the effect of one infrastructure can lead to one or more cascading failures in another infrastructure due to the dependency complexity between them. This article introduces a holistic approach using network indicators and machine learning to better understand the geographical representation of critical infrastructure. Previous work on a similar model was based on a single measure; such as in fashion, this paper introduces four measures utilized to identify the most vital geographic zone in the city. The model aims to increase resilience, focusing on the preparedness phase by assessing the essential nodes of infrastructure, which allows more space to adopt risk mitigation strategies before any disturbance event. Holding in-depth knowledge of the vital zones of small scales and accordingly ranking them will positively improve the overall system resilience.

Embracing Age-Inclusivity Through Multimodal, Active Student Learning in a Health and Aging Policy Course

One of the goals for an upper-level undergraduate seminar course is for students to identify and discuss existing policies, programs, and resources for meeting the needs of the aging population. To encourage active student learning, the course provides a mix of readings and assignments, six intergenerational discussions, and reflective writing. The idea is that these varying experiences help foster a deep understanding of how these policies and related issues pertain and matter to everyone, not only older individuals, and how their future career and family experiences will benefit from the knowledge gained in the course regardless of their next career steps. This course model has been effective for challenging ageism, and has been taught four times, each time with modifications based on student numbers, current issues, and the pandemic. The presenter will discuss assessment methods, identify best practices, and offer suggestions for others interested in utilizing a similar model.

ОСОБЛИВОСТІ ЗАСТОСУВАННЯ МЕТОДІВ ФІЗИЧНОГО МОДЕЛЮВАННЯ ДЛЯ АНАЛІЗУ ПРОЦЕСУ ПРИЗЕМЛЕННЯ ПАРАШУТНИХ ПЛАТФОРМ НА НАДУВНІ ПОВІТРЯНІ АМОРТИЗАТОРИ

Research has been carried out aimed at developing the theoretical bases of physical modelling of landing processes of parachute platforms on inflatable air shock absorbers. At the same time, the features of the application of physical modeling methods for solving this task are considered. The conditions, landing features and operation of parachute platform devices at landing on inflatable air shock absorbers are determined. It is shown that presently parachute-depreciation systems have become widespread, in which soft tissue shells are used, filled through the inlet openings with atmospheric or air injected from gas bottles air. The operation of these devices is based on the compression of air in the shell and expiration of him through exit holes (valves). At the same time, air inflatable shells absorb the kinetic energy of the impact, controlling the release of air through exit holes.It has been established that the most effective method for studying the behavior of a dropped vehicle is physical modelling, which uses a free-flying dynamically similar model (FDSM) or stand dynamically similar model (DSM) of a dropped object as an research object. Modeling of landing processes of parachute platforms on inflatable air shock absorbers is not related to the dynamics of the flight and air flow around surfaces. Therefore, for this task, the existing developments in physical modelling of dynamics flight cannot be applied, and for the theoretical substantiation of the dynamic similarity to modeling motion, it makes sense to use the laws of gas dynamics in regard to air shock absorbers.

Do Walking Distance and Time Away from the Paddock Influence Daily Behaviour Patterns and Milk Yield of Grazing Dairy Cows?

In pasture-based systems, cows may spend several hours away from the paddock and may also walk several kilometres to meet daily milking requirements; this could lead cows to experience time constraints for grazing, ruminating and lying time in the paddock. This study investigated how walking distance and time spent away from the paddock affected daily behavioural patterns (i.e., grazing, ruminating and lying time) and milk yield. Dairy cows were managed in three rotationally grazed groups (n = 29 cows each) on the same farm and milked twice daily. A triaxial ear tag accelerometer on each cow recorded daily duration of grazing and ruminating, and a leg-based accelerometer recorded the daily lying time, for 13 days. GPS collars on four cows per group recorded the daily walking distance and total time away from the paddock for the group. A mixed repeated measures model tested how time off-paddock and walking distance affected the daily behavioural patterns; age, breed, milk yield and maximum ambient temperature were used as covariates with group as the observational unit. A second similar model tested how these factors affected milk yield. Walking distance and time spent away from the paddock were not correlated. When daily walking distance increased (to a maximum of 4 km/d), cows spent more time grazing and less time ruminating, but lying time was not affected. This result may, in part, be related to the greater energy expenditure demands for walking longer distances and milk production. When time away from the paddock increased (to a maximum of 4 h/d), cows spent less time lying, but grazing and ruminating times were not affected. Milk yield was not affected by walking distance, but one of the groups experienced a lower milk yield when time away from the paddock was increased. This result suggests that, for some cows, lying times may be shorter when experiencing a longer time away from the paddock, which may also affect milk yield. Overall, this study indicates that paddock behaviours are associated with walking distance to the milking parlour and time spent away from the paddock. Efforts to reduce walking distance and time spent away from the paddock are likely to provide cows with greater opportunity to engage in daily behaviours in the paddock that meet their needs and maintain their milk yield.

Firearm laws and the network of firearm movement among US states

Background The movement of firearm across state lines may decrease the effectiveness of state-level firearm laws. Yet, how state-level firearm policies affect cross-state movement have not yet been widely explored. This study aims to characterize the interstate movement of firearms and its relationship with state-level firearm policies. Methods We analyzed the network of interstate firearm movement using Bureau of Alcohol, Tobacco, Firearms, and Explosives firearm trace data (2010–2017). We constructed the network of firearm movement between 50 states. We used zero-inflated negative binomial regression to estimate the relationship between the number of a state’s firearm laws and number of states for which it was the source of 100 or more firearms, adjusting for state characteristics. We used a similar model to examine the relationship between firearm laws and the number of states for which a given state was the destination of 100 or more firearms. Results Over the 8-year period, states had an average of 26 (Standard Deviation [SD] 25.2) firearm laws. On average, a state was the source of 100 or more crime-related firearms for 2.2 (SD 2.7) states and was the destination of 100 or more crime-related firearms for 2.2 (SD 3.4) states. Greater number of firearm laws was associated with states being the source of 100 or more firearms to fewer states (Incidence Rate Ratio [IRR] 0.58 per SD, p < 0.001) and being the destination of 100 or more firearms from more states (IRR1.73 per SD, p < 0.001). Conclusions Restrictive state-level firearm policies are associated with less movement of firearms to other states, but with more movement of firearms from outside states. The effectiveness of state-level firearm-restricting laws is complicated by a network of interstate firearm movement.

Model pendidikan nasionalis-religius Yahudi, dan refleksinya dalam pendidikan teologi di Indonesia

This paper examines the practice of teaching and learning in the education system in Israel and its central role in shaping students' national insight. The method used is a characteristic-thinking analysis which is reported qualitatively descriptively. The analysis results show that the Israeli education system based on religious teachings has succeeded in forming the national insight and spirit of nationalism of students, which is then referred to as religious nationalism. Through the Havruta system or learning in pairs, each student is guided to find the meaning of the text and apply the text in the practice of living within the framework of national identity. This study proposes that the Indonesian theological education system needs to develop a similar model within the Indonesian context. Further research is needed to develop typical Indonesian models to produce Christian theologians integrated as salt and light in maintaining Indonesian identity.AbstrakPaper ini mengkaji praktik belajar mengajar di dalam sistem pendidikan di Israel dan peran sentralnya di dalam membentuk wawasan kebangsaan peserta didik. Metode yang dipergunakan adalah cirical-thinking analysis yang dilaporkan secara kualitatif-deskriptif. Hasil analisis memperlihatkan bahwa sistem pendidikan Israel yang berbasis pada ajaran agama berhasil membentuk wawasan kebangsaan dan semangat nasionalisme peserta didik yang kemudian disebut sebagai nasionalisme-religius. Melalui sistem Havruta atau belajar berpasangan, setiap siswa dituntun menemukan makna teks dan menerapkan teks tersebut di dalma praktik kehidupan dalam kerangka identitas nasional. Penelitian ini mengusulkan bahwa sistem pendidikan teologi Indonesia perlu mengembangkan model serupa tetapi di dalam konteks keindonesiaan. Penelitian lanjutan diperlukan untuk mengembangkan model-model khas Indonesia untuk menghasilkan teolog Kristen yang terintegrasi sebagai garam dan terang di dalam mempertahankan identitas keindonesiaan.

Reconstruction of various navigational scenarios of the «Ever Given» ship, including grounding in the Suez Canal using the bridge simulator with up-to-date electronic navigation charts

The Suez Canal is the largest maritime shipping traffic thoroughfare in the world. The global cargo turnover accounts for 10-12%. Theaccident occurred on March 23, 2021 with the container ship “Ever Given”, blocking the Suez Canal. It fully paralyzed shipping traffic in the region and caused enormous damage to the economy. Reconstruction of various navigational scenarios of the containership, including grounding based on the bridge simulator, allowed examination of navigation and developing recommendations to prevent similar accidents in the future. Within the limits of the research, the authors used electronic navigation charts S-57 with up-to-date information on the accident time, a similar model of containership and hydro-meteorologic conditions in the bridge simulator’s session.An assessment of the risk of grounding a container ship has been carried out using the method of Bayesian trust networks.

Model-Independent Searches for New Physics in Multi-Body Invariant Masses

Model-independent searches for physics beyond the Standard Model typically focus on invariant masses of two objects (jets, leptons or photons). In this study, we explore opportunities for similar model-agnostic searches in multi-body invariant masses. In particular, we focus on the situations in which new physics can be observed in a model-independent way in three and four-body invariant masses of jets and leptons. Such searches may have good prospects in finding new physics in the situations when two-body invariant masses, which have been extensively explored at collider experiments in the past, cannot provide sufficient signatures for experimental observations.
