Revisiting Urban Guerrillas: Armed Propaganda and the Insurgency of Uruguay's MLN-Tupamaros, 1969–70

This article studies a singular aspect of the urban insurgency of Uruguay's MLN-Tupamaros: the tactic of armed propaganda. The Tupamaros applied the method mainly at the peak of their existence, in the years 1969–70. Afterward they opted predominantly for others, such as terrorism. By comparing the two periods, I argue that armed propaganda helped the organization to thrive, while the latter was an important cause of its demise. The conclusion suggests that armed propaganda led the Tupamaros to significant accomplishments, but also that switching tactics was a major determinant in their defeat.     

Trade liberalisation,rural poverty,and the environment: global discussions and local cases

Much has been researched and said about the impacts of international trade liberalisation at the country level; but little is known about its social and environmental local-level impacts. Since national averages can mask the existence of winners and losers, national-level studies may be a poor guide to addressing the plight of the rural poor and the environment that are at the core of the agenda of the social and conservation movement. This article compares the international trade-liberalisation debate with the findings of local rural-based case studies in seven countries, co-ordinated by WWF and the World Bank during 2004–2007. It discusses some actions that the conservation and social movement could take to improve the discussion and the practice of trade liberalisation, poverty alleviation, and environmental conservation.     

Scope of liability: the vanishing distinction between negligence and strict liability

The duty-of-care requirement cannot be used anymore as the touchstone to differentiate negligence from strict liability because it can be found in many forms of the latter. Duty of care is smuggled into strict liability hidden under the scope of liability requirement (traditionally called “proximate causation”). As far as the scope of liability requirement is common to negligence and to many forms of strict liability, there is a fairly large common ground to both liability rules, and consequently the marginal Hand formula is applied to both rules. Indeed, under a negligence rule, the marginal Hand formula is applied twice: first to assess whether or not the defendant did breach his or her duty of care, and, second, to delimit whether or not the defendant’s behavior was a proximate cause of the harm suffered by the victim. However, under a strict liability rule, the Hand formula is applied only once when the proximate causation question is raised. Traditional law and economics analysis has almost always taken the normative question raised by the causation requirement as given, which is a potential major problem due to the importance of scope of liability or proximate causation in legal practice. Defining the scope of liability, that is to say, the boundaries of the pool of potential defendants, is the basic legal policy decision for each and every liability rule. In the normative model presented in this paper, the government first chooses efficient scope of liability, and given the scope of liability, the government then decides the liability rule and damages that guarantee efficient precaution. In the article, most known scope of liability rationales developed by both common law and civil law systems are discussed in order to show the substantial common ground between negligence and strict liability.     

Results of the GEP-ISFG collaborative study on two Y-STRs tetraplexes: GEPY I (DYS461, GATA C4, DYS437 and DYS438) and GEPY II (DYS460, GATA A10, GATA H4 and DYS439)

A collaborative exercise was carried out by the Spanish and Portuguese ISFG Working Group (GEP-ISFG) in order to evaluate the performance of two Y-chromosome STR PCR tetraplexes, which include the loci DYS461, GATA C4, DYS437 and DYS438 (GEPY I), and DYS460, GATA A10, GATA H4 and DYS439 (GEPY II). The participating laboratories were asked to type three samples for the eight markers, using a specific amplification protocol. In addition, two control samples, with known haplotypes, were provided. The results obtained by the 13 different participating laboratories were identical, except for two laboratories that failed to type correctly the same two samples for GATA C4. By sequence analyses, two different GATA C4 allele structures were found. One control sample (allele 21) and two questioned samples (allele 22, correctly typed by all the laboratories, and allele 25) presented the following repeat structure: (TCTA)4(TGTA)2(TCTA)2(TGTA)2(TCTA)n, but different from the one found for allele 26 in one sample included in this exercise, as well as in the second control sample (allele 23), namely (TCTA)4(TGTA)2(TCTA)2(TGTA)2(TCTA)2(TGTA)2(TCTA)n. The collaborative exercise results proved that both Y-tetraplexes produce good amplification results, with the advantage of being efficiently typed using different separation and detection methodologies. However, since GATA C4 repeat presents a complex structure, with alleles differing in sequence structure, efficient denaturing conditions should be followed in order to avoid typing errors due to sizing problems.     

Rural Mobilisation and Agrarian Political Economy in Argentina, 2001–2020

In this article, we reconstruct the mobilisations of rural actors both from ‘below’ and from ‘above’ and their connections to Argentina's agrarian political economy between 2001 and 2020. We divide the analysis into three periods and review key protest events and the actions of movements and organisations, paying special attention to two dimensions. First, we consider how rural movements and organisations engaged with institutional politics and the state. Second, we analyse the collective identifications and claims at the basis of coalitions forged within and beyond the rural sector.     

Indicators of electoral victory

We explore the role that campaign expenditures play in determining electoral outcomes. We study a two-party contest where campaign funds can affect the preferences of voters regarding the saliency of two political issues. We show that an advantage in campaign resources, a pre-campaign partisan advantage, an advantage on every salient issue, or a combination of these indicators, do not always guarantee electoral victory. By contrast, electoral victory is guaranteed if the sum of the proportions of the electorate supporting a party on every salient issue is greater than a critical value. For that to happen it is necessary (but not sufficient) that the party has an advantage on every salient issue.     

Public Service Motivation and Job Sector Choice: Evidence from a Developing Country

This article explores the determinants of actual job sector decisions of highly skilled professionals across four different sectors in a developing country, with a particular interest in the relationship with public service motivation (PSM). Unlike most previous cross-sectional studies, it uses a pooled time series of individual antecedents and job characteristics, both before and after the individuals leave the job market to pursue graduate education abroad. The results indicate that there are key differences in terms of the determinants of job sector choices across the four sectors, and that PSM appears to have a differential role on the attraction of individuals to each of those sectors.
