Adapting the propensity for angry driving scale for use in Australian research

Road rage is a topic that receives consistent attention in both the road safety literature and media. Before Australian research can address the underlying factors associated with road rage, there is a need for a valid instrument appropriate for use in this context. The present program of research consisted of two studies. Study 1 used a university sample to adjust the scoring technique and response options of a 19-item American measure of the propensity for angry driving with acceptable reliability and validity. In Study 2, Factor Analysis confirmed a one-factor solution and resulted in a 15-item scale, the Australian Propensity for Angry Driving Scale (Aus-PADS), with a coefficient alpha of .82 (N = 433). The Aus-PADS may be used in future research to broaden the Australian road rage literature and to improve our understanding of the underlying processes associated with road rage in order to prevent the problem. Future research should also confirm the factor structure and generate normative data with a more representative sample

Beyond Corporate Form: A Response to Dan Depasquale, Surbhi Sarang, and Natalie Bump Vena’s Forging Food Justice Through Cooperatives in New York City

In their article, Forging Food Justice Through Cooperatives in New York City, Dan DePasquale, Surbhi Sarang, and Natalie Bump Vena (the “Authors”) argue that consumer-owned and worker-owned cooperatives hold promise as a means for advancing policy objectives associated with “food justice,” namely building community wealth and power and providing more affordable access to healthy food in low-income and minority communities. Looking to examples of legislation and policies in other jurisdictions, they advocate for a wide range of policies to promote the viability of cooperatives in New York City, including reforms to cooperative corporation laws and strategies for better allocating funding and technical assistance to cooperatives. I largely agree with the Authors’ argument and support their effort to identify practical policy solutions that would help food cooperatives in New York City overcome barriers to success. This Response makes three observations about their proposals. First, this Response observes that food access and economic development are distinct objectives and that consumer and worker cooperatives may have different roles to play in food justice strategies depending on how these objectives are defined and prioritized. Second, the significance of cooperative corporation statutes may be overstated, both because a variety of legal entity forms are available to cooperative organizations (mitigating the impact of potential reforms to New York’s cooperative corporation law) and because the legal form itself does not guarantee adoption of many of the values and principles commonly associated with cooperatives. Third, this Response argues that the role of other, non-cooperative organizational models should not be overlooked in shaping policy in this area. This Response advocates for a more comprehensive strategy that promotes a wide range of community-based businesses and organizations, including but not limited to cooperatives, and that allocates resources according to the identity of organizations’ stakeholders and the degree of their community impact, rather than relying on their legal form

Avulsion fracture of the Iliac Crest : a clinical and radiological evaluation 17 years later

The authors present the case of a sports-related avulsion fracture of the iliac crest, which happened in 1987, in an 18-year old adolescent. This was diagnosed using plain radiography, and was managed non-surgically. They recently reviewed the patient both clinically and radiologically and are here reporting their findings 17 years down the line.peer-reviewe

Mesiodens preventing eruption of a permanent central incisor

A maxillary midline supernumerary tooth is the most common type of supernumerary tooth. We present a case of a mesiodens, preventing eruption of a permanent central incisor. The aetiology, diagnosis and the effect of these developmental anomalies upon the dentition are discussed.peer-reviewe

Crucifixion and median neuropathy.

Crucifixion as a means of torture and execution was first developed in the 6th century B.C. and remained popular for over 1000 years. Details of the practice, which claimed hundreds of thousands of lives, have intrigued scholars as historical records and archaeological findings from the era are limited. As a result, various aspects of crucifixion, including the type of crosses used, methods of securing victims to crosses, the length of time victims survived on the cross, and the exact mechanisms of death, remain topics of debate. One aspect of crucifixion not previously explored in detail is the characteristic hand posture often depicted in artistic renditions of crucifixion. In this posture, the hand is clenched in a peculiar and characteristic fashion: there is complete failure of flexion of the thumb and index finger with partial failure of flexion of the middle finger. Such a "crucified clench" is depicted across different cultures and from different eras. A review of crucifixion history and techniques, median nerve anatomy and function, and the historical artistic depiction of crucifixion was performed to support the hypothesis that the "crucified clench" results from proximal median neuropathy due to positioning on the cross, rather than from direct trauma of impalement of the hand or wrist

The Complicated Evolution of the ACIS Contamination Layer over the Mission Life of the Chandra X-ray Observatory

The Chandra X-ray Observatory was launched almost 19 years ago and has been delivering spectacular science over the course of its mission. The Advanced CCD Imager Spectrometer is the prime instrument on the satellite, conducting over 90% of the observations. The CCDs operate at a temperature of -120 C and the optical blocking filter in front of the CCDs is at a temperature of approximately -60C. The surface of the OBF has accumulated a layer of contamination over the course of the mission. We have been characterizing the thickness, chemical composition, and spatial distribution of the contamination layer as a function of time over the mission. All three have exhibited significant changes with time. There has been a dramatic decrease in the accumulation rate of the contaminant starting in 2017. The lower accumulation rate may be due to a decrease in the deposition rate or an increase in the vaporization rate or a combination of the two. We show that the current calibration file which models the additional absorption of the contamination layer is significantly overestimating that additional absorption by using the standard model spectrum for the supernova remnant 1E 0102.2-7219 developed by the International Astronomical Consortium for High Energy Calibration. In addition, spectral data from the cluster of galaxies known as Abell 1795 and the Blazar Markarian 421 are used to generate a model of the absorption produced by the contamination layer. The Chandra X-ray Center calibration team is preparing a revised calibration file that more accurately represents the complex time dependence of the accumulation rate, the spatial dependence, and the chemical composition of the contaminant. Given the rapid changes in the contamination layer over the past year, future calibration observations at a higher cadence will be necessary to more accurately monitor such changes.Comment: 15 pages, 10 figures, SPIE Astronomical Instruments and Telescopes 2018, Conference Series, 1069
