Age‐Dependent Fracture Characteristics of Rigid and Compliant Surface Impacts on the Infant Skull—A Porcine Model*,†

Abstract: This study documents skull fracture characteristics on infant porcine specimens under known impact conditions with respect to age and interface. A single impact causing fracture was conducted on the skull of porcine specimens aged 2–28 days (n = 76). Paired rigid and compliant impacts at the same energy were conducted at each specimen age. Impact force, impact duration, and fracture length were recorded. Energy required to initiate skull fracture increased with specimen age. For a given energy, impact of the skull with a compliant interface caused more fracture damage than with a rigid interface for specimens aged under 17 days, but less damage for specimens aged 24–28 days. The documentation of energy required to cause fracture and resulting fracture propagation with respect to impact interface and age may be of critical importance in forensic investigations of infant skull trauma.     

Public service motivation and continuous organizational change: Taking charge behaviour at police services

Building change capabilities into public organizations is a challenge for strategic management. This study focuses on the micro‐level of extra‐role behaviours that contribute to continuous improvements in working procedures at the front‐end of organizations (i.e., taking charge behaviour; TCB). More particularly, we examine public service motivation (PSM) as a key variable mediating between perceived practices and TCB of street‐level bureaucrats. The analyses are based on survey data from a state police force in Germany (N = 1,165). Results confirm the role of PSM as full mediator, but this mediation is limited to the relationship between leadership behaviours and TCB, while perceived organizational characteristics—except for red tape—have direct positive impact on TCB.     

Balancing alternatives and avoiding false dichotomies to make informed U.S. electricity policy

Recent events highlight the importance of electric energy policy and how to meet growing electricity demand. Price spikes, global climate change and other environmental concerns, national security threats, an aging infrastructure, and a restructured industry with mixed results are challenges that policy makers and the industry must address. Given the capital-intensive nature of the industry, investment decisions will determine in large part how successfully these challenges are met. One paper that favors energy efficiency, renewable energy, and small-scale distributed generation is examined in detail to test the proposition that fossil fuel and nuclear power should be part of the mix of new investments. To determine the future electricity resource mix requires having a complete and informed picture of the relative costs and benefits of various technologies. The levels of energy efficiency, renewable resources, and distributed generation can and should be increased, but coal and nuclear generation investments are also likely to be needed.

From Loss of Services to Loss of Support: The Wrongful Death Statutes, the Origins of Modern Tort Law, and the Making of the Nineteenth-Century Family

The wrongful death statutes enacted in most states during the mid-nineteenth century have long represented a classic moment in the narrative of American legal history. Historians have not observed, however, that American wrongful death statutes amended the English act on which they were modeled to introduce a gender asymmetry peculiar to the United States. Led by New York, most American jurisdictions limited wrongful death actions to "the widow and next of kin" of the decedent, categories that did not include husbands of deceased wives. Thus, a wife could bring a wrongful death action for the death of her husband, but a husband could not bring a wrongful death action on his own behalf for the death of his wife.
The wrongful death statutes represent a heretofore unrecognized conjuncture of the beginnings of the modem law of torts with the nineteenth-century legal reconstruction of the family. The statutes mowed accident litigation away from an eighteenth-century model of masters suing for loss of the services of a servant, slave, wife, or child, toward the now more familiar model of suits for loss of wages and support. Moreover, the gender asymmetry of the statutes embodied and reproduced a new nineteenth-century conception of the family in which men worked as free laborers and women were confined to relatively narrow domestic roles, removed from the market and dependent for their support on the wages of their husbands. Indeed, the statutes anticipated by over half a century the American welfare state's two-track approach to support for wage-earning men and dependent women.     

Classification of Porcine Cranial Fracture Patterns Using a Fracture Printing Interface,,

Distinguishing between accidental and abusive head trauma in children can be difficult, as there is a lack of baseline data for pediatric cranial fracture patterns. A porcine head model has recently been developed and utilized in a series of studies to investigate the effects of impact energy level, surface type, and constraint condition on cranial fracture patterns. In the current study, an automated pattern recognition method, or a fracture printing interface (FPI), was developed to classify cranial fracture patterns that were associated with different impact scenarios documented in previous experiments. The FPI accurately predicted the energy level when the impact surface type was rigid. Additionally, the FPI was exceedingly successful in determining fractures caused by skulls being dropped with a high‐level energy (97% accuracy). The FPI, currently developed on the porcine data, may in the future be transformed to the task of cranial fracture pattern classification for human infant skulls.     

Persistence of Polydimethylsiloxane Condom Lubricants

Polydimethylsiloxane (PDMS) is commonly used to lubricate condoms. The detection of PDMS on swabs from complainants can be used to support an allegation of sexual assault. Previous research has focused on establishing analytical techniques for detecting PDMS. This research examined the persistence of PDMS on the penis, in the vagina, in the mouth, and on skin. The longest PDMS detection times were 20 h on the penis, 35 h in the vagina, and 52 h on skin. PDMS was detected up to 4 h in the mouth if the participant did not eat or drink and up to 9 h if the participant slept. PDMS was not detected in the mouth after eating or drinking. The presence of biological fluids had no detrimental effect on the analysis. Aqueous extraction of swabs for DNA did not remove any significant amount of PDMS; hence, swab remains could be subsequently analyzed for PDMS.     

Emotional Responses to Bureaucratic Red Tape

Although red tape has a long history in public administration research, the emotional consequences of bureaucratic procedures for citizens have received little attention in the literature. Within the framework of behavioral public administration, this article investigates how varying conditions of administrative delay, administrative burden, and rule dysfunctionality in citizen-state interactions spark discrete emotional reactions. Physiological measurements of emotions (e.g., facial coding, electrodermal activity, heart rate) from 136 participants in a laboratory study show that bureaucratic red tape evokes significant negative emotional responses, especially confusion, frustration, and anger. Experimental evidence also indicates that delay is less stirring than burden, while rule functionality has little placatory effect, regardless of the favorability of outcomes. These results support the conceptualization of red tape as an affective rather than a cognitive phenomenon. They also suggest that negative emotions of citizens are linked to the modus operandi of public administrations.
