Effective and Efficient Route Planning Using Historical Trajectories on Road Networks
Authors: Tian Wei , Shi Jieming , Luo Siqiang , Li Hui , Xie Xike , Zou Yuanhang 
Published: August 2023

We study route planning that utilizes historical trajectories to predict a realistic route from a source to a destination on a road network at given departure time. Route planning is a fundamental task in many location-based services. It is challenging to capture latent patterns implied by complex trajectory data for accurate route planning. Recent studies mainly resort to deep learning techniques that incur immense computational costs, especially on massive data, while their effectiveness are complicated to interpret.This paper proposes DRPK, an effective and efficient route planning method that achieves state-of-the-art performance via a series of novel algorithmic designs. In brief, observing that a route planning query (RPQ) with closer source and destination is easier to be accurately predicted, we fulfill a promising idea in DRPK to first detect the key segment of an RPQ by a classification model KSD, in order to split the RPQ into shorter RPQs, and then handle the shorter RPQs by a destination-driven route planning procedure DRP. Both KSD and DRP modules rely on a directed association (DA) indicator, which captures the dependencies between road segments from historical trajectories in a surprisingly intuitive but effective way. Leveraging the DA indicator, we develop a set of well-thought-out key segment concepts that holistically consider historical trajectories and RPQs. KSD is powered by effective encoders to detect high-quality key segments, without inspecting all segments in a road network for efficiency. We conduct extensive experiments on 5 large-scale datasets. DRPK consistently achieves the highest effectiveness, often with a significant margin over existing methods, while being much faster to train. Moreover, DRPK is efficient to handle thousands of online RPQs in a second,e.g., 2768 RPQs per second on a PT dataset,i.e., 0.36 milliseconds per RPQ.

Published: August 2023

ZusammenfassungDie physikalischen Eigenschaften pneumatischer Antriebe ermöglichen den Bau von sicheren, leichten und intuitiv bedienbaren Robotern, deren Regelung jedoch herausfordernd ist. Gründe dafür sind die Dynamik der Pneumatik und nichtlineare Reibung mit Unsicherheiten, die ohne abtriebsseitige Momentensensorik unbekannt ist. In dieser Arbeit wird die nichtlineare modellbasierte Trajektorienfolgeregelung eines Roboters mit sechs pneumatischen Drehgelenken vorgestellt. Sie umfasst die Mechanik und Pneumatik sowie, im Gegensatz zum Stand der Technik, deren Verkopplung in einem zentralen Regler. Ausgehend vom dynamischen Modell des Gesamtsystems wird der Regler mittels Feedback-Linearisierung, einem Sonderfall der differentiellen Flachheit, hergeleitet. Die Regelung wird experimentell validiert und anhand der Messungen werden praktische Auswirkungen ihrer Struktur aufgezeigt.
The Irresistible Simplicity of Preventing Harm
Authors: Sharkey Catherine M. 
Published: August 2023

Abstract
In Loomis v. Amazon.com, the California Court of Appeal confronts the most pressing products liability issue of our time: the extent to which an online marketplace is liable for injuries caused by defective products sold on its platform. In a trailblazing concurrence destined to enter the torts canon, Justice John Wiley highlights Amazon’s ability to influence the safety of the products it makes available for sale, and uses the case to remind us that the “deep structure of modern tort law” is built to “minimize the social costs of accidents.” Similarly, Justice Wiley cuts a clear path through the thicket of the economic loss rule, institutional (or vicarious) liability and punitive damages cases by following the torts lodestar: the irresistible simplicity of preventing harm.

Para-kin relationship between fans and idols: a qualitative analysis of fans’ motivations for purchasing idol-dolls
Authors: Zhang Zhenyu 
Published: August 2023

Abstract

Purpose
The purpose of this research is to examine how “mother fans” impact on the existing patterns of parasocial relationships between fans and idols and to gain deeper insights into the motivations underlying the purchase of idol dolls. Additionally, by including the experiences and perspectives of male idol fans, the research seeks to broaden the understanding of fan behavior and enhance comprehension of the motivations driving idol-doll consumption.

Design/methodology/approach
Taking idol-doll buyers as research objects, this research conducted textual analysis and in-depth interviews to explore fans’ motivations for purchasing idol dolls.

Findings
Idol doll purchases are driven by emotional attachment, particularly among mother fans who seek to establish a sense of control and maintain a mother–child relationship. Additionally, buying idol dolls can also serve as a disguise for girlfriend fans to cover up their romantic fantasies about their idols. Moreover, idol dolls serve as semiotic identifiers, attracting like-minded fans and gaining community recognition. It should be noted that male idol fans, who are considered deviant from the masculine normative, face scrutiny in female-dominated communities, needing further proof of authenticity.

Practical implications
This research promotes understanding the motivations behind idol-doll purchases and can assist marketers in catering to the emotional needs of fans, particularly mother fans, by designing and marketing dolls that resonate with their desired sense of attachment.

Social implications
By recognizing and emphasizing the positive aspects of fan activities, this study contributes to the ongoing process of de-demonization and normalization of fandom. Additionally, this research also seeks to contribute to a more comprehensive understanding of the struggles and emotional needs of the Chinese young generation.

Originality/value
This study explores the under-researched mother-fan group’s emotional needs and their motivations of purchasing idol-dolls. It also acknowledges the distinct perspectives and experiences of male idol fans, providing a fresh and unique viewpoint on idol-doll consumption.
The group behaviour modelling of workers in the labor market
Authors: Shananin Alexander , Trusov Nikolai 
Published: August 2023

Abstract
We describe the mathematical modelling of the group behaviour of workers in the labor market. The worker receives the salary and seeks to improve his qualifications in order to receive higher wages. The worker enlarges his qualification by the investments in human capital. At a random moment of time, a vacancy appears that provides a jump in the worker’s salary. The mathematical model of the worker’s behaviour in the labor market is presented as an optimal control problem on an infinite time horizon. The paper presents the derivation of the Kolmogorov–Fokker–Planck equation for the Lévy process, which describes the behaviour of a large amount of workers within a social layer. The numerical solution of the Kolmogorov–Fokker–Planck equation and the calculation results are presented.
Pressure-correction projection method for modelling the incompressible fluid flow in porous media
Authors: Terekhov Kirill M. 
Published: August 2023

Abstract
This work is dedicated to the pressure-correction projection method for the volume-averaged Navier–Stokes system for porous media. A set of parameters controlling the presence of inertia and viscosity is introduced into the system. Switching parameters allows us to reduce the system to either the Brinkman system or the Darcy equation. Considering the jump in the parameters between mesh cells allows capturing the contact of media of different types, such as free-flow and porous media flow. We apply Chorin’s projection method to decouple the system. The splitting of the system yields a momentum conservation equation and an anisotropic pressure correction equation. We propose a combination of collocated finite-volume methods to solve the problem.

Published: August 2023

The emergence and wrong use of social media coupled with the lack of initiative for an acceptable learning strategy are factors for poor academic performance. Self-regulated learning improves academic performance, but there is a paucity of research on social media addiction, learning strategies and self-regulated learning. This study examined the role of social media addiction and learning strategy in undergraduates' self-regulated learning. Three hundred and fifty (350) participants conveniently sampled across four (4) universities in Nigeria responded to a structured questionnaire consisting of scales measuring variables of interest. Using Analysis of Variance and Independent T-test analyses, results showed that learning strategy and social media addiction have significant influence on self-regulated learning while gender had no significant influence on self-regulated learning. It is therefore concluded that social media addiction and learning strategy are determinants of self-regulated learning, and impacts on the academic performance of undergraduate students.
