Estimation of Gestational Age from Tooth Germs: Biometric Study of DentaScan Images

Abstract: The few available studies on fetal age estimation concern very small samples, and statistical analysis is sometimes inadequate. In this survey, we used germs of deciduous teeth to estimate fetal age. Forty‐nine fetuses and 40 mandibles were scanned, and observations and measurements were made on DentaScan images. After checking their repeatability and reproducibility (analysis of variance), we defined thresholds using Fisher’s linear discriminant analysis to calculate the probability that a fetus was over or below a predefined age threshold. The forensic threshold which is of particular interest in France is 22 weeks amenorrhea. Relationships between fetal age and deciduous germ measurements were then sought by multiple linear regression. The thresholds gave very good results: 91.84% of good probability for the threshold of 22 weeks amenorrhea with no chance of error. The most precise age evaluation obtained nevertheless gave a range of ±4.6 weeks amenorrhea, so greater accuracy is still needed.     

Standing for the client: on the interactional becoming of the criminal defence attorney1

In this essay, I explore the meaning of the legal profession (the defence attorney). I carry out my investigation in the interactional register. I suggest that we examine the profession of defence attorney as a professional identity in becoming. I localize the event of becoming in the first attorney-client interview. I propose that it is during the first encounter that the attorney comes to stand for the client as a legal counsel. I further propose that the analogy of ‘standing for’ be accessed empirically through an analysis of a recorded episode from the first attorney-client conference. For my methods I use a combination of frame analysis and conversation analysis. The two analyses show how the attorney becomes to stand for the client as a legal figure moulded in a series of interactional moves. By reformulating and reframing the ordinary talk that is introduced as an entry mode into an institutional relationship, the attorney and the client alter their discursive positions until the attorney assumes his professional identity, that is, becomes to stand for the client in legal action.

Hair analysis of seven bodybuilders for anabolic steroids,ephedrine, and clenbuterol

Several bodybuilders, all winners of international competitions, were arrested for trafficking of a number of doping agents including anabolic steroids, ephedrine, beta-adrenergics, human chorionic gonadotropin, antidepressants, and diuretics. In accordance with the recent French law against doping, the judge asked to test seven bodybuilders to identify doping practices. Hair and urine specimens were collected for analysis. After decontamination, a 100 mg hair strand was pulverized in a ball mill, hydrolyzed, extracted, and derivatized to be tested by GC/MS for anabolic steroids, beta-adrenergic compounds, ephedrine, and other doping agents. Urine was analyzed for anabolic steroids and metabolites, beta-adrenergic compounds, ephedrine, and human chorionic gonadotropin, in addition to a broad spectrum screening with GC/MS. The following compounds were detected in urine: ephedrine (29 and 36 ng/mL, n = 2), clenbuterol (0.2 to 0.3 ng/mL, n = 3), norandrosterone (4.7 to 100.7 ng/mL, n = 7), norethiocholanolone (0.9 to 161.8 ng/mL, n = 6), stanozolol (1 to 25.8 ng/mL, n = 4), methenolone (2.5 to 29.7 ng/mL, n = 4), testosterone (3 to 59.6 ng/mL, n = 7), epitestosterone (1 to 20.4 ng/mL, n = 7) and ratio testosterone/epitestosterone >6 for four subjects (18.5 to 59.6). The following drugs were detected in hair: ephedrine (0.67 and 10.70 ng/mg, n = 2), salbutamol (15 to 31 pg/mg, n = 3), clenbuterol (15 to 122 pg/mg, n = 6), nandrolone (1 to 7.5 pg/mg, n = 3), stanozolol (2 to 84 pg/mg, n = 4), methenolone (17 and 34 ng/ml, n = 2), testosterone enanthate (0.6 to 18.8 ng/mg, n = 5), and testosterone cypionate (3.3 to 4.8 ng/mg, n = 2). These results document the doping practice and demonstrate repetitive exposure to anabolic compounds and confirm the value of hair analysis as a complement to urinalysis in the control of doping practice.     

Participatory democracy and ethnic minorities: opening inclusive new spaces or reproducing inequalities?

In the past decade, Latin America has emerged as the epicentre of participatory democracy innovations. Proponents argue that participation should lead to more equitable access to public goods and a greater sense of political efficacy. There has been considerable debate in the academic literature and in the public sphere over the extent to which participation can produce these benefits. Yet, while Latin America has witnessed an explosion of participatory mechanisms and related academic attention, the literature has focused on socioeconomic dimensions. There has been little attention paid to the experiences of racialized groups, such as indigenous peoples and Latin Americans of African descent. Research suggests that in order for participatory mechanisms to produce positive outcomes, they must be inclusive and offer participants a forum for real deliberation, but how do groups that have faced barriers related to racism and discrimination engage in these initiatives? Drawing on evidence from indigenous Ecuadorian and Afro-Venezuelan citizen participants, this article argues that participatory mechanisms may reproduce the very types of inequalities that representative institutions are criticized for. Comparing cases across and within different jurisdictions reveals that certain conditions enhance the ability of ethnic minorities to benefit from involvement in participatory mechanisms.
