An investigation of gender differences in the components influencing the difficulty of spatial ability items

This study examines the role that gender differences play in the determination of the components influencing the difficulty of spatial ability items. Considerable research has examined the role of gender differences in spatial abilities, with sometimes contradictory findings. In general, the findings show that males tend to outperform females on spatial ability items. Other research has focused on determining the components of items that contribute to their difficulty. This research has usually been based on mixed-gender populations, however. The present study attempts to determine if gender influences the extent to which different components contribute to the difficulty of items. The results indicate that component difficulties show very little variation across gender. This finding supports the notion that any differences in raw scores observed for males and females are not due to differences in the manner in which males and females process spatial information or solve spatial ability items.

A biomechanical investigation of forces applied to the lift truck steering wheel: effects of posture,gender and hand contact on cumulative low back loading

Hand contact forces on a typical lift truck steering wheel were quantified in a laboratory to determine their effects on low back loading. A single muscle equivalent link segment model (3D Match) was used to estimate cumulative loading exposure variables at the L4/L5 intervertebral disc with and without hand contact forces. Hand contact forces significantly decreased cumulative L4/L5 compression in forward bending (FB) for males by 32% and females by 14%. Cumulative L4/L5 compression in males (37,023?±?2183?Ns) was not different from that in females (38,413?±?2224?Ns). When excluding hand contact forces, males had significantly greater cumulative L4/L5 compression (55,165?±?1593?Ns) in FB compared to females (43,255?±?1753?Ns). Hand contact forces on mobile equipment controls might result in decreased cumulative L4/L5 compression, especially in awkward trunk postures. Females may be further predisposed to injury resulting from exposure to cumulative load.     

Evaluation of the Click It or Ticket intervention in Utah

Objective

To evaluate the Click It or Ticket (CIOT) intervention conducted in Utah by comparing changes in safety belt use using observational safety belt surveys pre- and post-intervention.

Methods

Observational surveys of safety belt use for drivers and front seat passengers (collectively referred to as front seat occupants) were conducted before and after the media and enforcement blitz of the CIOT intervention. Data were collected from 16 urban sites during the daytime and nighttime. Logistic regression and generalized estimating equations were used to compute odds ratios for safety belt use adjusted for front seat occupant characteristics.

Results

Overall safety belt use was observed at 76.5% pre-intervention and 84.8% post-intervention, an improvement of 8.3% (95% confidence interval [CI]: 5.2%, 11.3%). Daytime and nighttime safety belt use improved by 7.8% (95% CI: 3.5%, 12.1%) and 9.7% (95% CI: 6.4%, 13.0%), respectively. While males showed a greater improvement (9.9%) in safety belt use when compared to females (5.7%); males were still less likely to use safety belts than females.

Conclusions

The CIOT intervention is associated with increased safety belt use at the sites observed in Utah, including among the two high risk groups targeted by the intervention: nighttime occupants and males.

Performance evaluation of ProJet multi-material jetting 3D printer

The purpose of this paper is to quantitatively evaluate the performance of a multi-material jetting 3D printer, ProJet 5500X, especially the capability for micro manufacturing. Unlike other single material 3D printer, ProJet 5500X uses photopolymers as the build material and wax as the support material. The building performance was evaluated by building a modified version of the standard benchmark model with a high-resolution printing mode. The dimensional error, forming quality and surface roughness of the printed parts have been measured and analysed using a microscope, a 3D coordinate measuring machine and a surface profilometer. Using wax as the support material, fine features as small as 0.25?mm, lateral features and sharper edges could all be properly built, despite the rough side surfaces observed in the printed part. Identical features (3?mm pins) were precisely built with an accuracy of 15?µm. The research provides first-hand detailed performance knowledge in the ProJet system for understanding the working principle and comparison with other 3D printing systems.     

Development of P/M Fe–P soft magnetic materials

Phosphorous is treated as an impurity in conventional steels owing to segregation of phosphorous and formation of brittle phosphides along the grain boundaries. It is responsible for cold and hot shortness in wrought steels. In conventional powder metallurgy, involving compaction and sintering, high phosphorous content (up to 0·7%) in Fe-based alloys exhibit attractive set of mechanical and magnetic properties. These powder-processed alloys suffer from increasing volumetric shrinkage during sintering as phosphorous is increased beyond 0·6%. Thus both cast as well as conventional powder metallurgy routes have their own limitations in dealing with iron?Cphosphorous alloys. Hot-powder forging was used in the present investigation for the development of high-density soft magnetic materials containing 0·3?C0·8% phosphorous to overcome these difficulties. It was observed that phosphorous addition improves the final density of the resulting product. It was further observed that hot-forged iron?Cphosphorous alloys have excellent hot/cold workability and could be easily shaped to thin strips (0·5?C1·0?mm thick) and wires (0·5?C1·0?mm diameter). The powder hot-forged alloys were characterized in terms of microstructure, porosity content/densification, hardness, soft magnetic properties and electrical resistivity. Magnetic properties such as coercivity 0·35?C1·24?Oe, saturation magnetization 14145?C17490 G and retentivity 6402?C10836 G were observed. The obtained results were discussed based on the microstructures evolved.
