This paper aims to test TV sponsorship bumper effects, for the same brand, on 30-s TV spot advertising.

An experimental study tests sponsorship bumpers and 30-s TV spot ads for eight brands, four familiar and four unfamiliar, using realistic stimuli and a sample representative of the US population.

Sponsorship boosts ad effectiveness and is measured by ad awareness and ad liking. Both effects were stronger for unfamiliar brands.

The results show that combining sponsorship with spot advertising has an additive effect. The study design did not allow tests for potential synergy (multiplicative) effects.

Advertisers can use the results to evaluate investing in sponsorship and advertising packages, which can help unfamiliar brands achieve familiar brand awareness.

To the authors’ knowledge, this is the first study to compare the effectiveness of sponsorship-boosted ads with sponsorship bumpers alone and with TV spot ads.

The purpose of this study is to evaluate the 3D printability of a multimaterial, fully self-supporting auxetic structure. This will contribute to expanding the application of additive manufacturing (AM) to new products, such as automotive suspensions.

An experimental approach for sample fabrication on a multiextruder 3D printer and characterization by compression testing was conducted along with numerical simulations, which were used to support the design of different auxetic configurations for the jounce bumper.

The effect of stacking different auxetic cell modules was discussed, and the findings demonstrated that a one-piece printed structure has a better performance than one composed of multiple single modules stacked on top of each other.

The quality of the 3D printing process affected the performance of the final components and reproducibility of the results. Therefore, researchers are encouraged to further study component fabrication optimization to achieve a more reliable process.

This research work can help improve the manufacturing and functionality of a critical element of automotive suspension systems, such as the jounce bumper, which can efficiently reduce noise, vibration and harshness by absorbing impact energy.

In previous research, auxetic structures for the application of jounce bumpers have already been suggested. However, to the best of the authors’ knowledge, in this work, an AM approach was used for the first time to fabricate multimaterial auxetic structures, not only by co-printing a flexible thermoplastic polymer with a stiffer one but also by continuously extruding multilevel structures of auxetic cell modules.

The production of car bumper composites based on glass fibers and carbon fibers has been a continuous trend. These materials have standard properties; however, they are very expensive and are not readily available. Therefore, focus on the choice of reinforcement fibers is gradually shifting toward natural sources. Natural fibers are becoming attractive alternatives to traditional high‐performance fibers such as glass and carbon fibers for reinforcement in composites in structural applications. To produce a car bumper that will be less expensive and available leads to the development of Momordica angustisepala fibers (MAf) and anthill particles/ polyester hybrid composites.

The composite was produced by hand lay method. The physical, mechanical, microstructure and thermal properties of the composites were used as criteria for the selection of the material for car bumper application. The validation of the tensile properties was done using the finite element method.

The results should impact energy of 7.82J/mm2, 145.28 per cent improvement in tensile strength of the polyester increased by the addition of 6wt per cent MAf, and 5wt per cent anthill particles. Flexural modulus of 2269.01 and 2435.19 Mpa and flexural strength of 56.61 and 85.45 Mpa were obtained for the polyester and composite. The maximum temperature of decomposition was 370.00 and 472.00oC for polyester and composite. Validation of the tensile properties shows that with the difference between predicated yield strength the experimental gave a percentage error of 6.43 per cent and safety of 68.12 per cent. It can be concluded that the composite formulation with 6 wt per cent MAf and 5 wt per cent anthill particles in polyester can be used in the production of car bumper because the mechanical properties obtained are within the ranges used for car bumper application.

The composition of 5 wt per cent anthill particles and 6 wt per cent MAf in polyester has never been used in the production of car bumper before now; hence this work is novel and contributed to knowledge materials development.

Anglair Ltd's Product Finishing Division Leicester has supplied the advanced paint plant that has recently come on stream at the Banbury plant of Caradon Rolinx for priming thermoplastics automotive bumper mouldings.

A pilot project at the Ford Motor Co. plant in Genk, Belgium, uses robot‐guided waterjets to cut holes in bumpers for Sierra cars.

Efforts have been made to turn empty water sachet (commonly called pure water nylon), palm kernel shell and iron filings, which are all wastes released into the environment from different sectors of production in Nigeria into a useful material of good physical and mechanical properties. These wastes, especially the empty water sachet, pose a great challenge on the effort of achieving a clean and safe environment, mostly by their contribution to flooding during the rainy season. A recycling aimed research was carried out, making use of these materials to produce a new composite material and proffer suggestions for the possible use of the newly developed composite material. The empty water sachet was used as a matrix, which was reinforced by carbonized palm kernel shell particulate and iron filings. The percentage composition of iron fillings was maintained at 5%wt, while that of palm kernel shell ash was varied from 5%wt - 20%wt at an interval of 5%. The composites were compounded and compressively moulded. Physical and mechanical properties of the composites were tested for and the results obtained shows that the composite material could be used to produce automobile bumper among other parts due to their Impact Strength and low Density. After results analysis, materials with 5%wt of CPKS and that with 10%wt of CPKS were recommended for the automobile bumper production following their high impact strength - density ratio of 0.26 and 0.19 respectively, which are higher as compared to that of Peugeot 406 bumper measured alongside the composite materials.

Companies in general have not lived up to their ethical responsibility in assisting workers in decreasing workrelated accidents and illnesses. This paper presents a systematic four‐stage employee involvement model that was successful in transforming a company’s culture to become a model for preserving workers’ rights to safe working conditions. By changing the prevailing management ideology on safety, the model offers a positive solution to improving workplace safety and morale, while preserving the workers’ rights to be involved in decisions that affect the quality of their lives.
