To solve the problem that traditional trajectory prediction methods cannot meet the requirements of high-precision, multi-dimensional and real-time prediction, a 4D trajectory prediction model based on the backpropagation (BP) neural network was studied. First, the hierarchical clustering algorithm and the k-means clustering algorithm were adopted to analyze the total flight time. Then, cubic spline interpolation was used to interpolate the flight position to extract the main trajectory feature. The 4D trajectory prediction model was based on the BP neural network. It (...) was trained by Automatic Dependent Surveillance – Broadcast trajectory from Qingdao to Beijing and used to predict the flight trajectory at future moments. In this paper, the model is evaluated by the common measurement index such as maximum absolute error, mean absolute error and root mean square error. It also gives an analysis and comparison of the predicted over-point time, the predicted over-point altitude, the actual over-point time and the actual over-point altitude. The results indicate that the predicted 4D trajectory is close to the real flight data, and the time error at the crossing point is no more than 1 min and the altitude error at the crossing point is no more than 50 m, which is of high accuracy.

Artificial intelligence is a cutting-edge technology that has been widely applied in tourism operations. To enhance tourists' experience, many tourism suppliers introduced AI devices to interact with tourists. Previous studies classified AI devices as task- and social- oriented based on their functions; however, current models that explain customers' intention to use AI devices did not reflect the discrepancy between the two different types. Therefore, this paper attempts to fill this gap by proposing a theoretical model for the use of task-oriented (...) AI devices. Based on the multi-stage appraisal framework and the Structural Equation Modeling analysis, this paper presents the following findings: utilitarian motivation, interaction convenience, and task-technology fit are the factors appraised in the first stage; perceived competence and flow experience are the factors appraised in the second stage; utilitarian motivation, interaction convenience, and task-technology fit are positively associated with perceived competence. Perceived competence positively influences flow experience, which further affects customers' switching intention from task-oriented AI devices to human service; the serial mediating effect of perceived competence and flow experience between the stimulus mentioned in the first appraisal stage and the switching intention is confirmed. This study reveals the underlying psychological mechanism when customers use task-oriented AI devices, and it provides a theoretical framework for task-oriented AI device adoption. (shrink)

Wearing a myoelectric prosthesis is a basic way for limb amputees to restore their lost limb functions in the activities of daily living. However, it is estimated that around 40% of amputees refuse the prosthesis. One of the primary reasons would be that the current prostheses lack appropriate sensory feedback. Currently, the amputees only depend on their visual feedback when using their arm prostheses. It would be difficult for them to accurately control the wrist position, which is vital for flexible (...) manipulation in ADLs. This manuscript designed a myoelectric arm prosthesis with wrist position feedback. To study the effect level of position feedback on prosthetic control, two tests were performed. The vibrotactile perception range test aims to analyze the perception sensitivity of the vibration in humans and obtain the optimal perception range utilized in the sensory feedback test. The sensory feedback test analyzes the effectiveness of the position feedback by comparing three feedback methods of Vis-FB, WP-FB, and a combination of Vis-FB and WP-FB. These tests were conducted by asking six able-bodied subjects to perform 20 movement combinations of five target positions. The WP-FB was transiently activated with five vibrating motors embedded in an armband to stimulate the arm stump when the prosthetic wrist rotates to the target positions. Our experimental results showed that when WP-FB was added to the prosthetic control, the absolute angular error of the prosthetic wrist declined from 4.50° to 1.08° while the success rate 3 increased from 0.34 to 0.84, respectively. This study demonstrates the importance of WP-FB to the effective control of the arm prosthesis. (shrink)

Based on elaboration likelihood model, this paper introduces the central route and peripheral route of online comments and constructs a conceptual model affecting consumers’ clothing impulse buying behavior in live broadcast. A total of 737 questionnaires were collected, and 709 valid questionnaires were used for questionnaire analysis. According to the ELM, there are central route and peripheral route of online comments. The results show that in addition to the commentator credibility, the comment quality, comment comprehensiveness, and comment quantity have a (...) significant positive impact on impulse buying behavior. Fashion involvement plays a moderating role in the relationship between online comments and impulse buying behavior. This paper will provide theoretical support for live broadcast clothing marketing and provide suggestions for the development and design of live broadcast. (shrink)

This article identifies an argument in Hobbes’s writings often overlooked but relevant to current philosophical debates. Political philosophers tend to categorize his thought as representing consent or rescue theories of political authority. Though these interpretations have textual support and are understandable, they leave out one of his most compelling arguments – what we call the lesser evil argument for political authority, expressed most explicitly in Chapter 20 of Leviathan. Hobbes frankly admits the state’s evils but appeals to the significant disparity (...) between those evils and the greater evils outside the state as a basis for political authority. More than a passing observation, aspects of the lesser evil argument appear in each of his three major political works. In addition to outlining this argument, the article examines its significance both for Hobbes scholarship and recent philosophical debates on political authority. (shrink)

Given that care duties are central to the definition of motherhood across contexts, an extended separation from the woman’s family due to migration presents a major threat to her social identity as a mother and wife. Drawing on West and Zimmerman’s notion of “doing gender” and ethnographic research on Vietnamese low-waged contract workers in Taiwan, I provide vital insights into the discursive processes and everyday practices that underlie migrant women’s negotiations of motherhood and femininity. Specifically, I examine the various ways (...) migrant women perform and negotiate meanings of hy sinh and chịu đựng that are core values of Vietnamese womanhood. Combating the stigma of bad motherhood and failed femininity, I emphasize, is not just about reasserting one’s sense of gendered self but also about reassuring her access to the future support and care of the family. The study emphasizes intentionality and pragmatism in women’s social doings of gender and highlights moral dilemmas in gender politics. (shrink)

An account of how the mathematical sciences turn the mind away from becoming and towards being. There are four main conclusions. 1. The study of numbers, when treated independently of the other sciences, uses a particular conception of the nature of numbers to detach the mind from the influence of perceptible objects. 2. The study of ratios and proportions, explicitly the core of Plato's harmonics, is fundamental also to plane and solid geometry and astronomy. 3. Ratios and proportion form the (...) basis for the synoptic vision of all the mathematical sciences. This vision is an essential preparation for dialectic because it makes mathematicians become aware of the limitations of the mathematics they have been engaged in but it also shows them how they can begin to overcome those limitations. 4. The main purpose of the study of numbers, treated finally in relation to the other sciences, is to calculate ratios. (shrink)

This study examines values and value types as well as scores in levels of moral reasoning for␣students enrolled in a business program. These two factors are measured using the Schwartz Personal Values␣Questionnaire and the Defining Issues Test 2. No statistically significant differences in levels of moral␣reasoning, rankings of values, and value types could be attributed to gender. However, eight significant correlations between value types and levels of moral reasoning provide evidence that a systematic relationship exists. The relationships are not only (...) internally consistent but also consistent with the model of values based on motivational goals (Schwartz S. H. and K. Boenke: 2004, Journal of Research in Personality , 38 230–255). (shrink)

In Toward a Good Society, the authors theorize a mutually empowering and growth-fostering society. They begin this journey in relational psychology, then depart along nine paths reconstructed from nine classic social science theories. This leads them to propose a new Golden Rule as simple as it is profound.

This essay is an attempt to look at economics from a Christian perspective in this time of crisis. This exploration is of great personal interest to me because I am a Christian and an economist. During my entire adult life, I have been trying to connect these two parts of who I am: my Christian faith and my vocation in economics. In the beginning of my career I focused more on the dialectic tension between economics and faith. As I have (...) grown older I have moved more towards a synthesis of economics and faith. (shrink)

This paper is aimed at investigating the differences in ethical perception between Mainland China and Hong Kong through qualitative analysis. The level of idealism and relativism of the informants are measured quantitatively. The qualitative analysis of the viewpoints of participants from Hong Kong and other Chinese cities offers a profound understanding of ethical perception. Contradicting previous studies, our research offers a fresh perspective, indicating that those with high idealism are not always the ones who condemn misconduct or advocate for whistle-blowing. (...) Interestingly, we noted that individuals with high relativism frequently consider and emphasize alternative perspectives, rather than merely condemning or advocating misconduct and whistle-blowing. Conversely, those with low relativism frequently exhibit more anger, regardless of their stance. This discovery suggests that high relativism could be beneficial for facilitating communication between conflicting parties. (shrink)

The article discusses the challenge of Indecent Theology to Latin American liberation theology and feminist theology in unmasking their implicit support for the binary, heterosexual norms of society. Althaus-Reid argues that theology is a sexual act, and provides rich metaphors and language for a vibrant sexual political theology. Her work undresses conventional Christian symbols by queering the intersection of theology, sexuality, and politics.
