Discrete Choice Analysis of Temporal Factors on Social Network Growth

Social networks like Facebook, X (Twitter), and LinkedIn provide an interaction and communication environment for users to generate and share content, allowing for the observation of social behaviours in the digital world. These networks can be viewed as a collection of nodes and edges, where users and their interactions are represented as nodes and the connections between them as edges. Understanding the factors that contribute to the formation of these edges is important for studying network structure and processes. This knowledge can be applied to various areas such as identifying communities, recommending friends, and targeting online advertisements. Several factors, including node popularity and friends-of-friends relationships, influence edge formation and network growth. This research focuses on the temporal activity of nodes and its impact on edge formation. Specifically, the study examines how the minimum age of friends-of-friends edges and the average age of all edges connected to potential target nodes influence the formation of network edges. Discrete choice analysis is used to analyse the combined effect of these temporal factors and other well-known attributes like node degree (i.e., the number of connections a node has) and network distance between nodes. The findings reveal that temporal properties have a similar impact as network proximity in predicting the creation of links. By incorporating temporal features into the models, the accuracy of link prediction can be further improved.

Clinical therapeutic effect of self-prescribed Sanhanchushi Tongbi on lumbar disc herniation

BACKGROUND Lumbar disc herniation(LDH)commonly occurs during spinal surgery;LDH is on the increase in younger patients and is classified as"paralysis"and"back pain."Sanhanchushi Tongbi(SPST)is a customized prescription.It disperses cold,relieves pain,removes cold from the meridians and viscera,and treats neuropathic pain.However,few studies have investigated its mechanism of pain relief.AIM To observe the clinical therapeutic effects on LDH treated with self-prescribed SPST.METHODS A total of 211 patients with LDH syndrome were divided into two groups:107 patients in the control group were treated with conventional massage combined with traction,and 104 patients in the observation group were treated with a combination of the control regimen and self-prescribed oral SPST.The patients were treated for 4 wk.Indices of traditional Chinese medicine(TCM)syndrome score and serum inflammatory factor levels were measured.RESULTS After therapy,the TCM syndrome score in the observation group was significantly lower than that in the control group(P<0.05).The main symptoms,clinical signs,daily activities,and Japanese Orthopedic Association scores in the observation group were significantly higher than those in the control group after therapy(P<0.05).The levels of tumor necrosis factor-α,interleukin-6,and C-reactive protein were lower in the observation group than in the control group(P<0.05).In the observation group,superoxide dismutase levels were significantly higher,whereas malondialdehyde levels were significantly lower,compared with the control group(P<0.05).The overall efficacy rate in the observation group was 96.15%,which was substantially higher than that in the control group(88.79%;P<0.05).CONCLUSION Self-prescribed SPST can reduce the levels of inflammatory and pain-causing factors as well as lumbar pain in patients with LDH.

Psychological Influence Factors Analysis of the New Generation Employees’ Moral Choices from the Perspective of Cognitive Neurology

At present,the academic researches on moral choices focus mainly on the individuals’external behaviors,without fully considering the influences of the individuals’internal psychological factors.Based on the model of complete information static games in the Non-cooperative Game theory,the present research has designed a“Red and Blue Experiment”to explore the psychological influencing factors of the new generation employees’moral choices.The research has conducted psychoanalysis on the new generation employees through experiments and interviews with 118 data sources,and concluded the characteristics in relation to the different stages of psychological processes and moral choices of the experimental population.Through comparative analysis,it is found that:the psychological factors,such as trust,doubt,and guilt will influence the new generation employees’moral choices,guiding them to make choices,such as risk aversion and mutual benefit and win-win,in the process.Additionally,the research has also provided effective scientific evidence for the new generation employees’mental health development and career planning.

The Continuous Analogy of Newton’s Method for Solving a System of Linear Algebraic Equations

We propose a continuous analogy of Newton’s method with inner iteration for solving a system of linear algebraic equations. Implementation of inner iterations is carried out in two ways. The former is to fix the number of inner iterations in advance. The latter is to use the inexact Newton method for solution of the linear system of equations that arises at each stage of outer iterations. We give some new choices of iteration parameter and of forcing term, that ensure the convergence of iterations. The performance and efficiency of the proposed iteration is illustrated by numerical examples that represent a wide range of typical systems.

Influencing Factors and Path Choice of Rebuilding Rural Financial Supervision System

The necessity of rebuilding Chinese rural financial supervision system is expounded. Rebuilding rural financial supervision system is conducive to normalizing rural financial order and forming the benign competitive situation; to clarifying the role played by rural financial organization and providing better financial services for "three agriculture";to forming safe rural financial environment to promote the development of rural economy and national economy. The restricting factors of rebuilding Chinese rural financial supervision system are analyzed. The major reasons are that rural financial legislation is relatively backward and the supervision department lacks the necessary legal basis. The administrative supervision is insufficient, which lead to the mal-position, administrative offside and vacancy of rural financial supervision;rural financial organization mechanism is unreasonable and the internal supervision mechanism is relatively bad;supervision organization of rural financial industry is imperfect and the function is imperfect; public's supervision awareness is weak and social supervision mechanism develops slowly. The paths for rebuilding Chinese rural financial supervision system are put forward including accelerating rural financial legislation to provide perfect legal evidence for rural financial supervision system; clarifying the position on governmental functions and fully displaying the leading role of rural financial supervision; establishing specialized rural financial supervision organization to perfect its supervision functions; vigorously cultivating people's supervision awareness to promote the development of social supervision mechanism.

A Study of the Factors Affecting Choice of the Accounting Profession

An accounting professional is called a ＂Certified Public Accountant Financial Advisor （CPAFA）＂ in Turkey and the profession has a notable status in the country. Individuals choosing this profession have to complete a minimum 3-year internship program before becoming members of this profession. They have to pass an exam both to start and finish the internship program. The profession and the reasons for choosing it are highly significant issues. Therefore, the present study was conducted to investigate the factors directing the professional choices of prospective individuals who wish to be CPAFAs and the significance of such factors. Along with these objectives, a nation-wide study was conducted on candidates who took the CPAFA internship exam in periods of 2012-3, 2013-1, and 2013-2 （three periods）. The factors affecting candidates＇ choices to be an accountant professional were gathered under five groups. The factors ＂influence of immediate surroundings＂, ＂prestigious social status of the profession＂, ＂high life-long income potential＂, ＂flexible working hours＂, and ＂future guarantee of the profession＂ had higher factor loadings than other factors.
