The Relationship

This article investigates whether the presence of immigrants represents an opportunity for Italian tourism firms to increase the number of establishments and their employees. To this scope, we focus on the hotels and restaurants sector where a great amount of revenues comes from the tourist expenditure. The investigation is conducted at both the nationwide level and, separately, for Centre-Northern and Southern provinces. As estimation technique, in order to deal with the potential endogeneity problem, we will proceed with the two-stage least square method. The results strongly support a positive relationship between the provincial share of immigrants and the number of tourism establishments and their employees. This relationship seems to be stronger for southern provinces.

Elastic Characteristics

We investigated the relationship between kinematic and kinetic characteristics of foot joints resisting ground reaction force (GRF). Passive elastic characteristics of joint were obtained from the experiment using three cameras and one force plate. The relationship between joint angle and moment was mathematically modeled by using least square method. The calculated ranges of motion were 7o for TM joint, 4o for TT joint and 20o for MP joint. With the model that relates joint angle and plantar pressure, we could get the kinematic data of the joints which are not available from conventional motion analysis. The model can be used not only for biomechanical analysis which simulates gait but also for the clinical evaluations.

The phenomenon of false financial statements still exists. However, in addition to the risk of being punished, what kind of price do companies have to pay? In recent decades, with China's rapid progress in economic, the relevant accounting system and corporate governance standards are actively improving, and the earnings quality is improving. This paper takes China's listed companies from 2015 to 2019 as samples, and adopts quantile regression supplemented by ordinary least square method to explore the relationship between earnings quality and capital cost. The research findings show that the higher the earnings management, the higher the capital cost, especially for the company with low capital cost. Nevertheless, for the extremely company with high capital cost, earnings management can reduce the capital cost. The research results can provide the focus of regulators of listed companies and reference for the revision of relevant accounting system.

The Relationship

Manajemen dan nilai perusahaan memiliki keterkaitan yang tidak dapat dipisahkan.  Dimana manajemen perusahaan merupakan penggerak roda perusahaan dan berorientasi pada nilai perusahaan. Peran seorang manajer adalah memaksimalkan kekayaan bagi pemegang saham.  Namun, manajer yang tidak memiliki kepemilikan saham yang signifikan di perusahaan dapat memilih untuk memaksimalkan keuntungan bersih mereka sendiri dengan mengorbankan pemilik perusahaan. Akibatnya, pemilik terpaksa mengeluarkan biaya agensi untuk memastikan bahwa manajemen perusahaan bertindak dengan cara yang tepat. Cara untuk mengurangi biaya agensi adalah memaksa perusahaan untuk meningkatkan hutang. Tujuan penelitian adalah  menguji hubungan simultan pertukaran antara ownership, leverage, dan nilai perusahaan sehubungan dengan keagenan pada perusahaan manufaktur di Indonesia dari tahun 2012-2018. Penelitian ini menambah pemahaman mengenai keterkaitan antara ownership dengan leverage, dan nilai perusahaan. Analisis data untuk argumen tentang keterkaitan simultan antara  ownership, leverage, dan nilai perusahaan melalui data panel regresi berganda 2 SLS (Two Stage Least Square). Bidang penelitian ini diperluas dengan mempertimbangkan model empiris di mana ownership dan leverage masing-masing diperlakukan sebagai variabel endogen atau ditentukan bersama.  Dalam metode 2 SLS ada 2 kali variabel yang diobservasi secara simultan untuk menghindari bayes sehingga variabel tersebut tidak bias, di mana variabel managerial ownership dan Leverage merupakan determinan non linier nilai perusahaan sebagai bagian integral dari pengambilan keputusan perusahaan dalam kerangka keagenan.  Persamaan Regresi hasil uji 2SLS memunjukkan keterkaitan nilai perusahaan dengan managerial ownership dan leverage. Hasil menunjukkan interaksi positif  tidak signifikan antara managerial ownerhip dengan nilai perusahaan, interaksi positif signifikan antara nilai perusahaan dengan leverage, dan interaksi yang negatif signifkan antara managerial ownership dengan leverage. Management and corporate value have an inseparable relationship. Where the company management is the driving force of the company and oriented to corporate values. The role of a manager is to maximize wealth of shareholders. However, managers who do not have a significant share in the company may choose to maximize their own net profits at the expense of the company owners. As a result, the owners are forced to incur agency costs to ensure that company management acts in an appropriate manner. The way to reduce agency costs is to force the company to increase debt. The research objective is to examine the exchange simultaneous relationship between ownership, leverage, and corporate value with respect to agency in manufacturing companies in Indonesia from 2012-2018. This study adds to the understanding of the relationship between ownership and leverage, and corporate value. Data analysis for arguments about the simultaneous relationship between ownership, leverage, and firm value through 2 SLS (Two Stage Least Square) multiple regression panel data. This field of research is extended by considering empirical models in which ownership and leverage are treated as endogenous or co-determined variables, respectively. Ownership and Leverage as an integral part of corporate decision making within an agency framework, which in turn will affect the value of the company. In the SLS 2 method, there are 2 variables that are observed simultaneously to avoid bayes so that the variable is not biased, in which the managerial ownership and leverage variables are nonlinear determinant corporate value as an integral part of corporate decision making within the agency framework, which in turn will affect firm value. The 2SLS regression equation results show the relationship between firm value and managerial ownership and leverage. The results prove that there is a positive interaction between managerial ownership between firm value, a significant positive interaction between firm value and leverage, and a significant negative interaction between managerial ownership and leverage.

The Relationship

The failure mechanism of rubber materials under accelerated stress in aging process may be different from that under normal conditions. Therefore, identification of the failure mechanism consistency is necessary for the accelerated aging testing of rubber material. To solve the problem, we study the relationship between the aging velocity of permanent compression set value and aging time. Firstly, according to the relationship, the aging velocity constant is obtained through the least square method. Then, combining with the aging velocity constant, we found that the activation energy is equal to the slope of linear function about Arrhenius model. Based on that failure activation energy keeps same under same failure mechanism, an identification method about failure mechanism consistency is developed. Finally, to demonstrate and validate the proposed method, we take the accelerated aging testing for the nitrile rubber-26 sealing gasket as an example.

Based on the positive bias property of the time of arrival(TOA) measurement error caused by the non-line-of-sight(NLOS) propagation, a simple and effective three dimensional(3D) geometrical localization algorithm was proposed, the algorithm needs no prior knowledge of time delay distribution of TOA, and only linear regression was used to estimate the parameters of the relationship between the NLOS distance error and the true distance, thus, the approximate real distance between mobile terminal (MT) and base station (BS) was reduced, then, the 3D geometric localization of mobile terminal was carried out by the least square method. The experimental results shows the effectiveness of the algorithm, and the positional accuracy is far higher than the required accuracy by E-911 in NLOS environments.
