Influence of rubber compound and tread pattern of retreaded tyres on vehicle active safety

The aim of the article is to present the results of road tests of original and retreaded tyres, analysed in the aspect of vehicle active safety. The tests covered emergency braking, steady-state circular tests and severe lane-change manoeuvre. The tests were performed in summer and winter conditions. Original Michelin tyres and Michelin tyres retreaded with summer and winter rubber compounds were used. The results of the tests proved that vehicle active safety is affected by retreaded tyres. The differences between braking deceleration of a car with original tyres and braking deceleration of a car with retreaded tyres confirmed the necessity of performing braking tests on the place of accident with the set of tyres with which the vehicle participating in the accident was equipped.     

Mothers’ Attitudes Toward Corporal Punishment of Children in Qazvin-Iran

The aim of this study was to assess mothers’ attitudes toward Corporal Punishment (CP) of children in Iran. A qualitative study was carried out using focus group discussions. Five sessions were held among 42 participants (30 mothers and 12 caregivers). Results indicated that 80% of participants used CP to bring up their children; 70 % did not know the meaning, predisposing factors, and manifestations of child abuse, and more than 50 % did not know the complications resulting from CP and the ways of preventing. Their attitude toward CP was that the use of CP was sometimes necessary to bring up their children while their information about predisposing factors and complications of child abuse might be minimal. The findings have been used in providing an educational package with the topics of parenting skills in order to decrease child abuse that has been resulted by parents.     

Forensic investigation of cross platform massively multiplayer online games: Minecraft as a case study

Minecraft, a Massively Multiplayer Online Game (MMOG), has reportedly millions of players from different age groups worldwide. With Minecraft being so popular, particularly with younger audiences, it is no surprise that the interactive nature of Minecraft has facilitated the commission of criminal activities such as denial of service attacks against gamers, cyberbullying, swatting, sexual communication, and online child grooming. In this research, there is a simulated scenario of a typical Minecraft setting, using a Linux Ubuntu 16.04.3 machine (acting as the MMOG server) and Windows client devices running Minecraft. Server and client devices are then examined to reveal the type and extent of evidential artefacts that can be extracted.     

Exploring political personalities: The micro-foundation of local policy innovation in China

This article argues that policymakers' individual attributes influence their willingness to engage in policy innovation, and that this influence is responsive to, but not determined by, changes in the institutional structure. We derive these findings by employing principal component analysis of original data from surveys of local policymakers in China, to inductively locate different personalities. We find statistically significant personalities that influence a willingness to innovate, and that this influence is responsive to changes such as heightened risk. In addition to parsing the influence of extrinsic and intrinsic motivations on policy innovation, we further find that the traditional risk-acceptant policy-entrepreneur personality does not explain innovation well.     

A literature review of partnerships

In today＇s competitive era, all organizations and enterprises, including small and medium enterprises （SMEs）, should have collaboration with each other to survive and they cannot be globally successful by working alone. A partnership is the relationship existing between two or more persons or entities that join to carry on a trade or business. Each one contributes money, property, labor or skill, and expects to share the profits and losses of the business. There are different types of partnerships, and organizations should inform from them and apply from it in suitable cases. Each partnership has its own advantages and disadvantages as well. This paper aims to describe some types of partnerships between governments, communities, new social movements and firms.
