The rise and fall of the legal expert system†

Those very few of us who were critical of the rise of legal expert systems in the early 1980s probably wonder, in idle moments, whether there is a possibility of rejuvenation of an approach which was once multi-various and is now obscure and esoteric. Is it possible that after rising and falling, that legal expert system research programme could rise again? What were the conditions which gave impetus to the field and could they be repeated? In this article I want to return, with a personal viewpoint, on the rise of expert systems and why - despite their failure - the appeal of commoditising legal expertise continues to allure the unwary.     

What does Brexit Tell Us about Our Understanding of European Identity?

This paper reports on a number of Eurobarometer surveys undertaken by the European Commission as a way of reflecting on Brexit and the challenges it poses to European identity. Our work with the surveys has been undertaken in the context of developing an educational game (RU EU?) which will explore European identity. European citizenship and identity have been strongly promoted by the EU but, while they appear to have been accepted at an elite level, the EU—and the UK in particular—have so far not constructed a narrative which has been supported by ‘ordinary’ citizens. Brexit has therefore exposed the failings of European elites in this regard. That said, there is some evidence that the complexities of Brexit have led to a strengthening of European identity in the other EU 27 countries.     

Authoritarianism,socioethnic diversity and political participation across countries

It is argued in this article that threatening stimuli affect political participation levels among non‐authoritarians more than among authoritarians. Focusing on socioethnic diversity, which is known to be particularly threatening to authoritarians and to relate negatively to political participation in the general public, analyses of individual‐ and macro‐level data from 53 countries is presented which supports this thesis. Participation levels among authoritarians are largely static, regardless of a country's level of socioethnic heterogeneity, while non‐authoritarians participate considerably less in countries with relatively high levels of socioethnic heterogeneity. This suggests that authoritarians participate to a proportionately greater degree in the most diverse countries.     

Associations Between Caregiver Support, Bullying, and Depressive Symptomatology Among Sexual Minority and Heterosexual Girls: Results from the 2008 Boston Youth Survey

Although sexual minority (SM) youth are at an increased risk for being bullied and experiencing depression, it is unclear how caregiver support is interrelated with those variables. Therefore, we sought to assess: (a) the prevalence of nonphysical bullying, depressive symptomatology, and caregiver support among heterosexual and SM girls, (b) the association between caregiver support and bullying in both groups, and (c) whether sexual orientation moderates the interactive effect of caregiver support and bullying on depressive symptoms. Data come from a survey of students in 22 Boston public high schools; 99 of the 832 girls in the analytic sample were SM. We used chi-square statistics to examine group differences, and multiple regression to estimate the association between the caregiver support, sexual orientation, being bullied, and depressive symptomatology. SM girls reported similar levels of caregiver support as heterosexual girls, but reported higher levels of depressive symptomatology. They were also more likely to report nonphysical bullying. Tests for interactions were not statistically significant, suggesting that bullying, caregiver support, and sexual orientation are independently associated with depressive symptomatology.     

The detection of multiply charged dyes using matrix-assisted laser desorption/ionization mass spectrometry for the forensic examination of pen ink dyes directly from paper

Abstract:  Laser desorption mass spectrometry (LDMS) is emerging as a technique for questioned document examination. Its use is limited to detecting ink dyes that are neutral or singly charged. Several inks contain dyes that are multiply charged and LDMS cannot be employed for their identification. We have successfully detected >20 polyionic dyes that can be used in the manufacture of inks using matrix-assisted laser desorption/ionization (MALDI) MS, directly from paper, with the matrix, 2-(4-hydroxyphenylazo)benzoic acid (HABA), and the additive, diammonium hydrogen citrate (DAHC). For example, Acid Violet 49, a charged dye containing one positively-charged site and two negatively charged sulfonate groups, cannot be detected by LDMS, but forms intact, singly charged ions in the MALDI MS experiment. The method described is also useful for identifying multiply charged dye mixtures that are used in modern pen inks.
