Test, track, and treat negative opinion outbreaks

Abstract Treads made with emulsion styrene-butadiene copolymer (SBR), solution SBR, polybutadiene (BR), and a 60/40 emulsion SBR/BR mixture were built as four-way tread sections on G78-15 belted bias tires, which were driven over both concrete and gravel-textured highways and on a small, circular, concrete test track. The tires were front mounted. When driven on concrete highway, all except the BR tread had either crumbled- or liquid-appearing surfaces, thought to have been formed by mechanical degradation or fatigue. When cornered on concrete, these materials formed small cylindrical particles or rolls. The BR tread had a smooth, granular-textured surface when driven on concrete highway and a ridge or sawtooth abrasion pattern when cornered on concrete. All the materials appeared rough and torn when run on gravel-textured highway. The differences in wear surface formed on BR tread and the other three are thought to be due primarily to the relatively high resilience of BR.

On The Road

A human-like trajectory could give a safe and comfortable feeling for the occupants in an autonomous vehicle especially in corners. The research of this paper focuses on planning a human-like trajectory along a section road on a test track using optimal control method that could reflect natural driving behaviour considering the sense of natural and comfortable for the passengers, which could improve the acceptability of driverless vehicles in the future. A mass point vehicle dynamic model is modelled in the curvilinear coordinate system, then an optimal trajectory is generated by using an optimal control method. The optimal control problem is formulated and then solved by using the Matlab tool GPOPS-II. Trials are carried out on a test track, and the tested data are collected and processed, then the trajectory data in different corners are obtained. Different TLCs calculations are derived and applied to different track sections. After that, the human driver’s trajectories and the optimal line are compared to see the correlation using TLC methods. The results show that the optimal trajectory shows a similar trend with human’s trajectories to some extent when driving through a corner although it is not so perfectly aligned with the tested trajectories, which could conform with people’s driving intuition and improve the occupants’ comfort when driving in a corner. This could improve the acceptability of AVs in the automotive market in the future. The driver tends to move to the outside of the lane gradually after passing the apex when driving in corners on the road with hard-lines on both sides.

Academic Study

Most recent historians have expressed a negative opinion of the quality of legal education at the English universities between 1400 and 1650. The academic study of law at Oxford and Cambridge, they have stated, was easy, antiquated and impractical. The curriculum had not changed from the form it assumed in the thirteenth century, and it did little to prepare students for their careers. This article challenges that opinion by examining the inner nature of the ius commune, the law that was applied in the courts of the church, and also by examining some of the works of practice compiled by English civilians during the period. Those works show that the negative opinion rests in part upon a misunderstanding of the nature of legal practice during earlier centuries. In fact, concentration on the texts of the Roman and canon laws, as old-fashioned as it seems to us, was well suited for the tasks advocates and judges would face once they left the academy. It also provided the stimulus needed for advance in the law of the church itself; their legal education made available to potential advocates and judges skills that would permit a sophisticated application of the ius commune, one better suited to their times. The article provides evidence of how this happened.1

How willing are employers to hire older workers? How willing are employers to hire older workers? In this article, we use a vignette study among employers in the public sector to investigate how the role of the job applicant’s age and employers’ views on productivity and the wages of older workers affect the likelihood that older applicants are hired. We find that the likelihood of being hired significantly decreases with the age of the applicant. A job applicant who is 60 years old, has a 41% lower chance of being hired than someone who is 35 years. Employers believe that the productivity of 55to 64-year-olds is lower and labor costs are higher than that of younger workers. However, a negative opinion on the labor costs of older workers has no significant impact on older applicants’ probability of being hired. A negative opinion of the employer on the relative productivity of older workers does substantially lower the probability that an older applicant will be hired.

Simulation Package

Abstract Bus operator’s workstations neglecting ergonomic features can cause overall discomfort and injuries to the users. This paper presents use of JACK®, a human work simulation package, in designing and evaluating a bus operator workstation which can provide sufficient visibility, natural reach, and comfortable posture for operators who range from the 5th percentile female to the 95th percentile male as defined by SAE J833 (SAE, 1994). Three human models representing the two extremes and their medium size person were created and performed 15 bus operating tasks on the bus workstation implemented in JACK®. Kinematic constraints were defined between the human models and the workstation to simulate the tasks in a realistic manner. While the human models simulated the tasks, the body joints were monitored to determine if they exceeded their comfort ranges recommended by Diffrient et al. (1981) and the workstation was evaluated in terms of visibility, reach, comfort, and adjustability. After the workstation design was refined by iterative modifications and the required component adjustment ranges were determined, the workstation design was prototyped into an actual working bus. A jury of bus operators evaluated the workstation design by operating the prototype on a test track. The response from the operators indicated that the workstation would accommodate the intended population.
