Is the Animal Liberation Front morally justified in engaging in violent and illegal activism towards animal farms?

The Animal Liberation Front (ALF) is an activist group, mainly focused on violent and illegal direct action, including destruction of property, the rescuing of animals and the clandestine filming of animal cruelty on animal farms. Here, I engage with three arguments that are often raised against the ALF’s actions, namely these actions are not morally justified because: (a) they are not measures of last resort; (b) they are excessively violent and do not discriminate targets; and (c) they have no reasonable probability of success. I contend that clandestinely filming animal cruelty is morally justified, the destruction of property is not and that rescuing animals is morally justified, if the ALF incorporates some changes as to how this is done.     

Internationalism Under Platform Capitalism: Brexit and the Organisation of UK Fast Food Workers

In October 2018, a coalition of UK trade unions and civil society organisations called a strike across the UK’s fast food sector in support of a living wage, union recognition and the end to zero‐hour contracts in the sector. This paper takes the day of action—labelled the McStrike—as a starting point for an account of the place of the EU and Brexit in the campaign for fast food rights, as well as the contrasting political standpoints adopted by the different trade unions involved in the action. Brexit is used as a prism through which to analyse aspects of Britain’s contemporary food politics, especially those pertaining to freedom of movement, workplace organisation, and the role of EU legislation in protecting workers’ rights. In exploring the international dimensions of union organisation among the UK’s fast food workers, other, more conceptual considerations regarding the changing nature of public and private food consumption and the incorporation of food‐to‐go into the gig economy are also broached.     

Comparison of methods to determine sex by evaluating the greater sciatic notch: Visual, angular and geometric morphometrics

Sex estimation is the first step for biological profile reconstruction of an unknown skeleton (archaeological or contemporary) and consequently for positive identification of skeletal remains recovered from forensic settings. Several tools have been developed using different osseous structures. With the intention to provide an objective method comparison, we reported the analysis of three different methods (visual, metric and geometric morphometrics) for sex assessment of the greater sciatic notch. One hundred and thirty pelvic bones (45.4% females and 54.6% males) from the National Autonomous University of Mexico Skeletal Collection pertaining to the contemporary Mexican population were analyzed. We used the ROC-analysis to test between desired false positive thresholds (1-specificity) and expected true positive rates (sensitivity) in order to predict the best approach to sex assessment. The comparison of the area under the ROC-curves shows significant differences among visual and metric methods. At the same time, the analysis suggested that higher morphological variation among the sexes is independent of the methodological approach. The results indicate that the metric (angle), with a high percent of indeterminate cases (34.6%), and visual, with 26.2% of the cases allocated as intermediate cases, were poorly accurate; we cannot recommend these techniques for sexing an unknown specimen. On the other hand, the geometric morphometrics approach improves sex estimation in 82.3% of correctly classified individuals with more than 95% of posterior probability. In addition to the method comparison, the major sexual variation of the greater sciatic notch was determined to be located on its posterior border.
