The effect of conditions of putrefaction on species determination in human and animal teeth

Tooth fragments freshly extracted from humans and rats were stored at either 4 degrees C or room temperature in dry or humid conditions for periods ranging from 1 to 6 months. The fragments were reduced to powder and antigens were extracted. Comparison of these samples was carried out using Counter Current Electrophoresis. Extracted sera were tested against known specific antisera and resultant precipitin reactions stained for examination. Correct species identification was possible both from desiccated and humid fragments but there was species variation in the sensitivity of the method. All the extracts from human teeth were positive against human antisera. In the rat some test specimens were initially negative but became positive following further dilution of the extracts.     

Phosphoglucomutase isoenzymes in human teeth

Powdered dentine samples were prepared from fresh teeth and teeth allowed to putrefy for up to 90 days. In some samples dentine only was included, whereas in others dentine plus pulp remnants were used. Extracts of the powders were tested for phosphoglucomutase activity by starch gel electrophoresis and PGM typing was carried out. Fresh teeth showed activity in at least 50% of cases as did putrefied dentine plus pulp remnants. Putrefied dentine alone showed minimal activity. The method may be useful for identification procedures using fragments of teeth.     

Compressed Development

In this paper we argue that the path of economic development for would-be developers has changed fundamentally since the 1980s. Focusing on East Asia, and taking a broad perspective that spans the economic and social dimensions of development, we contend that the path charted by the “late development” model has become all but impassible. The path is now better conceived as one of “compressed development.” Key differences are 1) the extent and consequences of compression; 2) the primary mode of engagement with the world economy—via global value chains; and 3) the interaction of these. Compressed development forces states to address a number of simultaneous challenges, resulting in “policy stretch.” We identify key features of an “adaptive state” suited to navigating the path of compressed development.     

Child Adjustment after Parental Separation: Variations by Gender,Age, and Maternal Experiences of Violence during Marriage

This study examined variations in children’s post-separation adjustment based on child characteristics (gender and age) and maternal experiences of intimate partner violence (IPV) during marriage. Mothers (N?=?147) recruited within 12 weeks of a divorce filing took part in two interviews three months apart. They reported on marital IPV at Time 1, and their children’s (47% female; ages 3–17) adjustment 3 months later at Time 2. Four aspects of child adjustment were assessed using a standardized measure (hyperactivity, emotional symptoms, conduct problems, peer problems). Mothers were classified as having experienced coercive controlling violence (CCV; 23.8%), situational couple violence (SCV; 27.9%), or no violence (48.3%) during marriage. Gender differences were found on one of the four child adjustment indicators: boys had higher levels of hyperactivity than girls. Among boys but not girls, hyperactivity scores varied based on age and IPV type. Implications for practitioners and researchers are discussed.

     

The Proposed ‘Common European Sales Law’: Legal Framework and the Agreement of the Parties

The European Commission's Proposal for a Regulation on a Common European Sales Law (‘CESL’) seeks to create a European scheme of contract law available for parties to choose to govern cross‐border contracts for the sale of goods, supply of ‘digital content,’ and for the supply of related services. This article explains the background to the Proposal, sketches out the purposes and scope of the CESL, and considers and criticises its legal framework (and in particular its relationship with private international law) and the key requirement of the parties’ agreement. In the author's view, the CESL scheme remains an unconvincing basis for the achievement of its economic purposes and, as regards consumer contracts, puts too much reliance on the agreement of the consumer as a justification for the loss of their existing protection under EU private international law rules.
