Small Overlap

Front Small Overlap (FSO), a new test mode introduced by IIHS is used for differentiating North American market vehicles on their safety ratings with the Top Safety Pick (TSP) status. Current paper describes a production ready version of a non-traditional (door insert) concept. Small overlap test mode demands occupant cage integrity which can be achieved from structural countermeasures in the Side Sill, A-pillar or Front body hinge pillar. These structural measures add mass and need lead time for development (not feasible for existing vehicles). Current study describes door insert design that can be incorporated into the doors for providing improved strength for small overlap loading conditions. Paper investigates composites / structural plastic design onto existing impact door beams (Within the available packaging space). The door insert, along with improved CAB deployment capability, would provide improvement on existing vehicle safety ratings.

The Way

Engine is the powerhouse for a combustion powered automobile. For the propulsion of automobile, engine must be mounted on vehicle safety. The way it is mounted on to vehicle is very important and plays a crucial role in determining the Noise vibration and handling (NVH) characteristics of an automobile. A proper designed mount should block the vibrations from the engine to automobile body and should not allow the effect of road unevenness on to the engine. Vibrations are generally due to power pulses during power stroke, which is reduced by properly designing flywheel, and unbalance of rotating and reciprocating parts, which is reduced to a maximum level possible and rest damped out at the mounts, generally, elastomers like rubber are utilized to damp the vibrations. When comes to All Terrain vehicle, mounts are under heavy loading conditions due to terrain on which vehicle is used. This paper discusses about the designing of such mounts to be used on BAJA SAE buggy.

Zero marking of the simple past is often listed as a common feature of child African American English (AAE). In the current paper, we review the literature and present new data to help clinicians better understand zero marking of the simple past in child AAE. Specifically, we provide information to support the following statements: (a) By six years of age, the simple past is infrequently zero marked by typically developing AAE-speaking children; (b) There are important differences between the simple past and participle morphemes that affect AAE-speaking children's marking options; and (c) In addition to a verb's grammatical function, its phonetic properties help determine whether an AAE-speaking child will produce a zero marked form.

Conducting Research

Background: Our laboratory recently confronted this issue while conducting research with undergraduate students at the University of Waterloo (UW). Although our main objective was to examine cognitive and genetic features of individuals with schizotypal personality disorder (SPD), the study protocol also entailed the completion of various self-report measures to identify participants deemed at increased risk for suicide. Aims and Methods: This paper seeks to review and discuss the relevant ethical guidelines and legislation that bear upon a psychologist’s obligation to further assess and intervene when research participants reveal that they are at increased risk for suicide. Results and Conclusions: In the current paper we argue that psychologists are ethically impelled to assess and appropriately intervene in cases of suicide risk, even when such risk is revealed within a research context. We also discuss how any such obligation may potentially be modulated by the research participant’s expectations of the role of a psychologist, within such a context. Although the focus of the current paper is on the ethical obligations of psychologists, specifically those practicing within Canada, the relevance of this paper extends to all regulated health professionals conducting research in nonclinical settings.

Abstract. The current paper explores whether self and observer reports of personality are properly viewed through a contrasting lens (as opposed to a more consonant framework). Specifically, we challenge the assumption that self-reports are more susceptible to certain forms of response bias than are informant reports. We do so by examining whether selves and observers are similarly or differently drawn to socially desirable and/or normative influences in personality assessment. Targets rated their own personalities and recommended another person to also do so along shared sets of items diversely contaminated with socially desirable content. The recommended informant then invited a third individual to additionally make ratings of the original target. Profile correlations, analysis of variances (ANOVAs), and simple patterns of agreement/disagreement consistently converged on a strong normative effect paralleling item desirability, with all three rater types exhibiting a tendency to reject socially undesirable descriptors while also endorsing desirable indicators. These tendencies were, in fact, more prominent for informants than they were for self-raters. In their entirety, our results provide a note of caution regarding the strategy of using non-self informants as a comforting comparative benchmark within psychological measurement applications.

State Variation

Abstract. Clinical and personality research consistently demonstrates that people can form unhealthy and problematic attachments to material possessions. To better understand this tendency, the current paper extends past research demonstrating that anxieties about other people motivate these attachments. These findings suggest that although object attachment generally correlates with poorer well-being, it may attenuate well-being deficits associated with insecurity about close relationships. The current paper presents two studies using converging correlational ( N = 394) and diary methods ( N = 413) to test whether object attachments’ association with poorer well-being is moderated by relationship uncertainties. We find that both trait (Study 1) and state (Study 2) insecurities about others eliminated, and in some cases reversed, the negative psychological correlates of object attachment. These effects, however, were only observed when focusing on between-person variation in both studies; within-person analysis demonstrated that state variation in object attachment predicted better psychological well-being. These results highlight a need for more nuanced studies of object attachment and well-being.

Greyscale Image

In the paper "Colour-to-Greyscale Image Conversion by Linear Anisotropic Diffusion of Perceptual Colour Metrics", Farup et al. presented an algorithm to convert colour images to greyscale. The algorithm produces greyscale reproductions that preserve detail derived from local colour differences in the original colour image. Such detail is extracted by using linear anisotropic diffusion to build a greyscale reproduction from a gradient of the original image that is in turn calculated using Riemannised colour metrics. The purpose of the current paper is to re-evaluate one of the psychometric experiments for these two methods (CIELAB L* and anisotropic Δ99) by using a flipping method to compare their resulting images instead of the side by side method used in the original evaluation. In addition to testing the two selected algorithms, a third greyscale reproduction was manually created (colour graded) using a colour correction software commonly used to process motion pictures. Results of the psychometric experiment found that when comparing images using the flipping method, there was a statistically significant difference between the anisotropic Δ99 and CIELAB L* conversions that favored the anisotropic method. The comparison between Δ99 conversion and the manually colour graded image also showed a statistically significant difference between them, in this case favoring the colour graded version.
