Dynamic Analysis of Rockets Launcher

This paper deals with dynamic analysis of rockets launcher on a moving vehicle. Mechanical model of a launch rail system with a rocket is represented as a set of solid bodies and deformable elements with a damped elastic support. These launch rail systems enable to fire rockets of different weights and geometric configurations. Unlike them, today´s multiple rocket launcher systems are located in containers. Movement of this type of mechanical system is described with three defined coordinates: movement of a rocket on a deformable ramp, curvature of the top of a deformable ramp and an angle of rotation of the ramp around its longitudinal axis. Mathematical model of the whole system, including rockets launcher and vehicle, represents a system of five nonlinear, nonhomogeneous differential equations of second order. This system is transformed to a system of 10 differential equations of the first order, suitable for numerical solving through the software package MATLAB. Rocket launcher designers can find the obtained simulation and experimental results, represented in a graphical form which is very useful during the development of a new and modification of existing constructions

Neuroticism and the psychosomatic model of workplace bullying

Purpose: To examine the role of neuroticism in the psychosomatic model of workplace bullying. Design/methodology/approach: A survey approach was used in this research. Partial Least Squares analyses on data from 127 participants were used to determine whether the effects of bullying on negative affect are independent of, or are moderated by, neuroticism. Findings: Revealed that neuroticism does not moderate the relationship between bullying and negative affect. Bullying and neuroticism were found to act independently on negative affect. The results supported the psychosomatic model of bullying. Research limitations/implications: Limitations are the nature of the sample, the use of self-report and cross-sectional data. Future research could use a larger sample, include multi-rater data, and a longitudinal research design. Practical implications: Dealing effectively with bullying is a concern for individuals and organizations. The findings highlight the need for anti-bullying policies. Management need to be trained in the prevention of bullying and in how to deal effectively with bullying. Victims should not be held accountable for the psychosomatic effects of bullying, the onus remains on managers and employers to prevent bullying from occurring. Originality/value: This paper extends the psychosomatic model of workplace bullying by examining the role of neuroticism. The findings have both theoretical implications for researchers in increasing understanding of the psychosomatic model of bullying, and practical implications for managers in organizations in terms of developing strategies for countering workplace bullying and its effects

The workplace experiences of apprentices and trainees: an interview study

The workplace bullying behaviors experienced by apprentices and trainees in personal service occupations (e.g., fitness, hairdressing and beauty) formed the focus of this study. The key aim was to lean from the apprentices and trainees about the forms of any negative behaviors to which they had been subjected, and about the effects on them of any such behaviors. A semi-structured interview approach was used in this study. The results reveal that the apprentices and trainees had been subjected to several behaviors that meet the definitions of bullying. The behaviors were found to have serious adverse effects on the apprentices/trainees

This paper examines the workplace bullying experiences of building and construction apprentices. The aims of the paper are to learn about the types of behaviours to which building and construction apprentices are subjected and to examine the reasons why a significant proportion of them neither confront the perpetrator of the behaviour nor report the behaviour, either within the organisation or externally. Individual semi‐structured interviews were used. The results indicate that the apprentices were subjected to a wide range of negative behaviours. There were several reasons for them neither confronting the perpetrator nor reporting the bullying, including fear of job loss and financial impact

The behavioral reactions of victims to different types of workplace bullying

The relationships between different types of workplace bullying and the reactions of victims were examined using six categories of bullying (threat to professional status, destabilization, isolation, overwork, verbal taunts, and violence) and three categories of reactions (assertiveness, avoidance, and seeking formal help). Participants were 127 employed undergraduates. Descriptive statistics and correlations were used to analyse the data. The findings revealed that avoidance reactions were the most common, followed by assertiveness and seeking formal help. As hypothesized, different types of bullying were associated with different types of reactions. Several practical implications derived from the findings were discussed suggesting that prevention is better than intervention
