Optical Characterization of Some Modern “Eco‐Friendly” Fibers*

Abstract: Fibers that are termed “eco‐friendly” or “biodegradable” by manufacturers are increasingly being used in textile products such as apparel and carpeting to appeal to the ever more environmentally aware public. As such, these modern fibers are expected to begin showing up more often in forensic casework, and it is important that the forensic examiner recognize them. This study employed polarized light microscopy (PLM) and Fourier transform infrared (FTIR) microspectroscopy to characterize selected fibers of azlon, polylactic acid (PLA), cellulose composites of alginate or chitin, and bamboo (viscose rayon). Fiber cross‐sections, refractive indices, melting points, solubilities, and FTIR measurements were conducted. Results indicate that the azlons and PLA fibers are easily distinguishable from other textile fibers by their optical and chemical properties. The cellulose composites show only small differences in comparison with other cellulose‐based fibers, while bamboo viscose rayon is indistinguishable from normal viscose rayon.     

The Utility of the Samworth and Gowland Age‐at‐Death “Look‐up” Tables in Forensic Anthropology*

Abstract: Accurate age‐at‐death estimates are crucial to forensic anthropologists when onstructing biological profiles aimed at narrowing a missing‐persons list and to allow for timely and efficient identification of an unknown victim. The present contribution evaluates the utility of three new age‐at‐death estimation techniques recently proposed by Samworth and Gowland (2007). Results indicate that, in the samples under study, the Samworth and Gowland estimates from the pubic symphysis and auricular surface perform similar to alternate phase methods. The combined method does not appear to further enhance either the precision or the accuracy of the single pubic symphysis age‐at‐death estimate. In conclusion, these new methods seem to be more robust to distribution deviations than originally proposed by Samworth and Gowland (2007). They are therefore suitable for immediate and reliable forensic usage in the United States and worthy of further research for their use in North American forensic contexts.     

The “Local” Migration State: The Site‐Specific Devolution of Immigration Enforcement in the U.S. South

This article examines the implementation of 287(g) authority and Secure Communities by several law enforcement agencies in Wake County and Durham County, North Carolina. I argue that despite being federally supervised programs, 287(g) and Secure Communities take shape within specific political, legal, policing, and biographic contexts, and, as such, take on a site‐specific form. I conclude that although site specificity is a characteristic of devolved immigration enforcement in the U.S. context, devolution also predictably relocates interior immigration enforcement to immigrant populations' spaces of social reproduction. Accordingly, programs like 287(g) and Secure Communities work at a suprasite level to amplify immigrant populations' everyday insecurities.     

The Biggest “Have” of Them All: Wal‐Mart and Its Litigation Outcomes in Slip‐and‐Fall Cases

Scholars have theorized that resource‐rich litigants known as the “haves” tend to succeed disproportionately in litigation when the adverse party is a “have‐not.” The traditional theory suggests that haves are able to use their wealth to secure better attorney representation and can use their frequent experience in litigation to tip the scales of justice in their favor, particularly when faced with “one‐shotters” whose involvement in litigation is infrequent. A remaining question, however, is whether some haves fare better than other similarly situated haves. Specifically, this article posits that the litigation strategy used by the defendant may also play a role in litigation outcomes. Companies that tenaciously fight claims that, in the short term, would be cheaper to settle might discourage otherwise valid claims in the future from being filed out of fear that the litigation will be a protracted battle. This article examines Wal‐Mart Stores, Inc. (Wal‐Mart)—the largest revenue‐generating company in the United States—to explore whether it fares better than other resource‐rich defendants. Wal‐Mart in particular has a reputation against settling cases and thus is an excellent vehicle to investigate this hypothesis. Appellate cases in an eleven‐year period involving slip‐and‐fall litigation were compiled, and the results show that Wal‐Mart did win at a higher rate than other defendants. Although more research is needed to explore fully the effect of litigation strategy on win–loss rates, this sample of cases demonstrates that Wal‐Mart is a more effective and victorious litigant.     

“Impossible Families”: Mixed‐Citizenship Status Couples and the Law

This article explores the complex and contradictory relationship between citizenship in the law and the immigrant reality of mixed‐citizenship family life through in‐depth interviews with individuals in mixed‐citizenship marriages. An examination of mixed‐citizenship marriage exposes the inadequacies of approaching citizenship as an individual‐centered concept. The data indicate that, though both immigration and citizenship laws focus on the individual, the repercussions of those laws have family‐level effects. Because of their spouses' immigrant status, many citizens are obliged by the law to live the immigrant experience in their own country or to become immigrants themselves.     

A Vision of Social‐Legal Change: Rescuing Ehrlich from “Living Law”

The hundredth anniversary of the original publication of Eugen Ehrlich's Fundamental Principles of the Sociology of Law is nearly upon us. The book earned high praise from Oliver Wendell Holmes, Roscoe Pound, and Karl Llewellyn as one of the outstanding works of its time. Ehrlich has been identified as an early legal realist, a pioneering figure in legal sociology, and a leading theorist of legal pluralism. In this retrospective review, I explain the strengths and weaknesses of this classic book. Ehrlich articulated an unsurpassed account of dynamic social‐legal change, an account that remains fresh and timely today.     

Asking the Sovereignty Question in Global Legal Pluralism: From “Weak” Jurisprudence to “Strong” Socio‐Legal Theories of Constitutional Power Operations

The article examines recent theories of legal and constitutional pluralism, especially their adoption of sociological perspectives and criticisms of the concept of sovereignty. The author argues that John Griffiths's original dichotomy of “weak” and “strong” pluralism has to be reassessed because “weak” jurisprudential theories contain useful sociological analyses of the internal differentiation and operations of specific legal orders, their overlapping, parallel validity and collisions in global society. Using the sociological methodology of legal pluralism theories and critically elaborating on Teubner's societal constitutionalism, the author subsequently reformulates the question of sovereignty as a sociological problem of complex power operations communicated through the constitutional state's organization and reconfigured within the global legal and political framework.     

“Bending” Evidence for a Cause: Scholar‐Advocacy Bias in Family Law

There are a number of salient public policy issues in the family law field that have invoked impassioned policy debates on a recurrent basis. In the absence of a body of research to address these critical concerns, advocates under the guise of social science scholarship have exacerbated the confusion and controversy by construing the scant available research evidence to justify their own ends, without regard to the relevance, quality, utility, and limitations of the studies. This is one of two articles on this problem that we have named “scholar‐advocacy bias.” In this article, we discuss the difference between truth in social science and truth in law. We identify common ways in which social science researchers and reviewers of research—wittingly or unwittingly—can become advocates for ideological positions and social policies at the expense of being balanced reporters of research evidence as illustrated by recent debates about overnight parenting of infants and toddlers. We also consider how adherence to established scientific principles and methods prevents the misuse of research in this way.     

Positive “Water Test”—An External Indicator of Base of Skull Hinge‐Ring Fracture

Abstract: Despite having significant internal injuries, victims of motor vehicle accidents may have surprisingly few external manifestations of trauma. The water test describes a technique whereby water placed in an upwardly facing ear results in drainage from the nose and opposite ear, thus demonstrating transcranial passage of water. This sign can be demonstrated in cases of blunt cranial trauma where there is a “hinge” fracture involving the petrous temporal bones bilaterally associated with a ring fracture extending around the foramen magnum posteriorly. Such a fracture results in separation of the posterior and middle cranial fossae providing a track for water to traverse. The water test provides a quick and noninvasive method for demonstrating the presence of a particular type of skull fracture.     

“YFlag” – A Single‐base Extension Primer Based Method for Gender Determination

Assigning the gender of a DNA contributor in forensic analysis is typically achieved using the amelogenin test. Occasionally, this test produces false‐positive results due to deletions occurring on the Y chromosome. Here, a four‐marker “YFlag” method is presented to infer gender using single‐base extension primers to flag the presence (or absence) of Y‐chromosome DNA within a sample to supplement forensic STR profiling. This method offers built‐in redundancy, with a single marker being sufficient to detect the presence of male DNA. In a study using 30 male and 30 female individuals, detection of male DNA was achieved with c. 0.03 ng of male DNA. All four markers were present in male/female mixture samples despite the presence of excessive female DNA. In summary, the YFlag system offers a method that is reproducible, specific, and sensitive, making it suitable for forensic use to detect male DNA.     

“Deliberative Disagreement” in U.S. Health Policy Committee Hearings

The exchange of rationales among debate participants is necessary for legitimacy in a deliberative democracy. I show that witnesses in congressional committee hearings tend to use falsifiable rationales when they encounter moderate levels of disagreement and shift to nonfalsifiable rationales when they encounter extreme disagreement. I use data from a coding of hearings testimony on the Medicare program, held between 1990 and 2003, as well as from a survey of participating witnesses measuring their perceptions of disagreement at the hearing. The results identify conditions that enhance falsifiable discourse and help to establish the empirical grounding deliberative democratic theory.
