Modification of the Marmarou and Foda model of diffuse axonal injury (DAI) improves percentage survival of rats at 24 h and increases the amount of DAI identified

More than two decades ago, Marmarou published a valid model for producing diffuse axonal injury (DAI) in rats. Since then, both mild and severe injuries have been obtained by researchers using the original method and a weight of 450 g. However, the diffuse brain injuries produced in rats were only similar to those seen in humans when the rats sustained severe brain injuries. In these cases, rat mortality in the original article was around 50%, and the cause of death was prolonged apnea post-impact. Rat survival after impact is critical for studying the progression of DAI. In order to explain the cause of death in human victims with cranial trauma who do not show gross brain injury, testing for the presence of DAI is essential. Thus, in order to minimize local and cervical injuries to increase rat survival, attention should be paid to the following aspects: a wider head protector disc should be used, the head of the rat should be elevated at the time of impact, and the foam bed should be soft enough to allow the movement caused by acceleration. With our modified method, rat survival increased by 30% compared to the original model (80% versus 50%). Moreover, 85.7% of rats demonstrated DAI after 24 h of survival. With these modifications, injuries appear in the same locations as in humans; thus, the method is suitable for the study of traumatic DAI in humans.     

Canine Population Data Generated from a Multiplex STR Kit for Use in Forensic Casework*

Abstract: Canine biological specimens are often part of the physical evidence from crime scenes. Until now, there have been no validated canine‐specific forensic reagent kits available. A multiplex genotyping system, comprising 18 short tandem repeats (STRs) and a sex‐linked zinc finger locus for gender determination, was developed for generating population genetic data assessing the weight of canine forensic DNA profiles. Allele frequencies were estimated for 236 pedigreed and 431 mixed breed dogs residing in the U.S. Average random match probability is 1 in 2 × 10³³ using the regional database and 1 in 4 × 10³⁹ using the breed dataset. Each pedigreed population was genetically distinct and could be differentiated from the mixed breed dog population but genetic variation was not significantly correlated with geographic transition. Results herein support the use of the allele frequency data with the canine STR multiplex for conveying the significance of identity testing for forensic casework, parentage testing, and breed assignments.     

An economic analysis of the in-prison therapeutic community model on prison management costs

This study estimated the impact of an in-prison, therapeutic community (TC) substance abuse treatment program on management costs in a California prison. A deconstruction method was developed to estimate the opportunity cost of staff time and other resources involved in various prison administrative tasks. Compared to “non-treatment” yards within the facility, the TC environment generated lower administrative costs for disciplinary actions, inmate grievances, and major disruptive incidents resulting in lockdowns. These findings suggest that, in addition to their intended rehabilitative outcomes, prison-based TCs may foster institutional environments that help to control prison management costs.     

Recurrent default or policy-optimal taxation

This paper investigates the syndrome of “this time is different” with respect to Reinhart and Rogoff’s (This time is different: eight centuries of financial folly Princeton University Press, Princeton, 2011) interpretation of their extensive, historical data on financial default, and with particular regard to public debt in a closed-economy. Recurrent and over-generous promises to credulous investors of an ex ante, policy-optimal return amounts to an extra policy instrument in boosting the demand for public debt. In a numerical simulation of a version of the Diamond (Am Econ Rev 55:1126–1150, 1965) model, we find that the incentive for the policy-maker to pursue this strategy is trivial if taxes can be set at a policy-optimal level, but possibly over-riding if they cannot. Thus, the main result lines up with the empirical conclusion of Reinhart et al. (Debt intolerance. Debt intolerance, 2003) that “debt intolerant countries have weak fiscal structures”. The subsidiary result of the model is that defaulting countries will also have higher shares of public expenditure. Thus the model also predicts Wagner’s Law to the extent that fiscal structure is correlated with economic development.     

Dental Age Estimation: Pattern Recognition of Root Canal Widths of Mandibular Molars. A Novel Mandibular Maturity Marker at the 18‐Year Threshold

The final stage of third molar development is used to assign a subject to above the 18‐year threshold. Some subjects exhibiting this final stage are less than 18 years. Radiographs from 1000 females and 1000 males age 16.00–25.99 years were examined. Each half‐year age band comprised 50 females and 50 males. Three categories of root canal widths (RCW) of the LL6, LL7, and LL8 [FDI 36, 37, and 38] were defined. Reproducibility was achieved by re‐assessing the same subjects 12 months apart. For females, the minimum value for RCW‐A was 16.33 years, RCW‐B 17.23 years, and RCW‐C 18.45 years. For males, the minimum values were RCW‐A 17.16 years, RCW‐B 18.29 years, and RCW‐C 18.16 years. The presence of RCW‐C in a female, and the presence of RCW‐B or RCW‐C in a male is compelling evidence that the subject is above the 18‐year threshold.
