Using Paint to Investigate Fires: An ATR‐IR Study of the Degradation of Paint Samples Upon Heating

Fire investigation is a challenging area for the forensic investigator. The aim of this work was to use spectral changes to paint samples to estimate the temperatures to which a paint has been heated. Five paint samples (one clay paint, two car paints, one metallic paint, and one matt emulsion) have been fully characterized by a combination of attenuated total reflectance Fourier transform infrared (ATR‐IR), Raman, X‐ray fluorescence spectroscopy and powder X‐ray diffraction. The thermal decomposition of these paints has been investigated by means of ATR‐IR and thermal gravimetric analysis. Clear temperature markers are observed in the ATR‐IR spectra namely: loss of ν(C = O) band, >300°C; appearance of water bands on cooling, >500°C; alterations to ν(Si–O) bands due to dehydration of silicate clays, >700°C; diminution of ν(CO₃) and δ(CO₃) modes of CaCO₃, >950°C. We suggest the possible use of portable ATR‐IR for nondestructive, in situ analysis of paints.     

The role of criminal record in the federal sentencing guidelines

In this paper my concern is with the collective moral responsibility of criminal investigators for the outcomes of their investigations, bearing in mind that it is important to distinguish collective moral responsibility from, and relate it to, individual moral responsibility. In what sense, if any, are police detectives individually and collectively morally responsible for their success (or, for that matter, their failure) in gathering sufficient evidence to identify, arrest, and charge an offender who has committed a serious crime? Alternatively, in what sense are they morally responsible in cases where they identify, arrest, and charge an innocent person? And in what sense, if any, are police detectives individually and collectively morally responsible for the ultimate outcome of the trial, the finding by the courts of someone they have investigated and charged with a serious crime to be guilty or innocent?     

MWB Business Exchange Centres Ltd: The Practical Benefit Doctrine Marches On

In MWB Business Exchange Centres Ltd v Rock Advertising Ltd the Court of Appeal held that when an ongoing contract is varied so that one party's obligation to pay money is reduced, the variation is binding as long as the other party receives a practical benefit. In doing so, the Court of Appeal effectively confined the rule in Foakes v Beer to one‐off payments. This raises serious questions about the continued survival of Foakes v Beer. On the other hand, the Court of Appeal ensured that Foakes v Beer would not be killed off via equity by moving away from the suggestion in Collier v P & M J Wright (Holdings) Ltd that an agreed part‐payment of a debt by a debtor will always raise an estoppel preventing the creditor from demanding the remainder of the debt.     

An archival exploration of homicide--suicide and mass murder in the context of 19th-century American parricides

There has been little attempt to integrate contemporary studies of suicide and mass murder to homicide-suicides. The current research attempts to do so in the context of 19th-century parricides in America. This project uses archival records from The New York Times and the Chicago Tribune, 1851-1899, resulting in a total of 231 incidents. Our results indicate that parricides, mass murders, and suicides tended to originate as spontaneous acts, usually during the course of an argument, gathering momentum as the interaction unfolded. We contend that suicide is one way of alleviating threats to offender's loss of self-identity.     

Government subsidies to private spending on public goods

This paper examines how the size of an efficient subsidy varies with the amount of free-riding and the presence of distorting taxation. Ironically, the existence of free-riding, where some individuals make no voluntary contribution at all, reduces the size of an efficient subsidy and makes a subsidy more attractive compared to direct taxation. For the gain to be significant, the number of donors must be extremely few in number. Even when the gains from a subsidy relative to direct taxation are small, a subsidy may dominate direct taxation because it can reveal an efficient level of the public good. The analysis distinguishes between traditional public goods such as national defense, and what I call transfer public goods, where members of society care about the consumption of a particular group in society such as the poor. I generalize the Samuelson (1954) results to derive conditions for efficiency in providing transfer public goods.

Decision-Making for Life Apart

… he (the layman) can understand the basic character of the English way of legal thinking, he can identify himself with it and, above all, can make his peace with it by retaining once and for all a solicitor as his legal father confessor for all contingencies of life (Max Weber, Economy and Society, 1922¹). The tendency in England and Wales is to use a solicitor's office as the automatic first port of call without first becoming aware of the range of services and the range of options which are available to separating and divorcing couples (Looking to the Future, 1995, para 7.3).     

Rape reform in Canada: Public knowledge and opinion

Rape reform legislation in Canada was designed to change: 1) the way sexual assault cases were processed by the criminal justice system and 2) public opinion about crimes of sexual aggression. This article reports findings from a representative survey of the Canadian public and an experimental analysis of the effects of the legislation on public knowledge and attitudes. Results from the nation-wide survey indicated that most people are unaware of the semantic shift (from the old language of rape and indecent assault to the new crimes of sexual assault). However, there is awareness of the substantive legal changes introduced by the rape reform legislation (such as the fact that husbands are no longer immune from criminal changes involving their wives). It is clear that rape reform legislation has affected public knowledge of statutory reforms regarding crimes of sexual aggression. Results from the experimental component of this research show that the new sexual assault label has not achieved one of the important goals, namely of changing public perceptions of the nature of crimes of sexual aggression. Indeed, one negative effect predicted by feminist writers seems to have emerged: sentencing decisions made by the public for the offense of rape were less severe when the incident was described as a sexual assault.
