Informality and Profitability: Evidence from a New Firm Survey in Ecuador

This article estimates the impact of informality on profits using a new survey administered to 1,200 firms with less than 50 employees in four cities in Ecuador. The article proposes a novel definition of informality which explicitly recognises that most firms comply with some regulations but not others. Accounting for firm selection and controlling for a large set of firm, owner and location characteristics, the article finds that more formal firms tend to be more profitable and have higher output per worker. This impact operates, inter alia, through improved access to credit and higher sales through issuance of tax receipts.

Breaking the Law to Ensure Order: The Case of Tijuana (2007–2012)

This paper explores how state agents and civilians justify human rights violations when the military perform police tasks. Based on a set of interviews and documents, it analyses the actions of the armed forces and the police during a military-led operation that targeted drug trafficking organisations in Tijuana. In a context of limited civilian control over the armed forces and the police, the paper identifies two discourses that supported the illegal action of state agents: the construction of a foreign other who does not belong to society and the need to use violence to accomplish a greater good.

Precarious employment conditions affect work content in education and social work: results of work analyses

Work content is adversely affected by precarious employment conditions, with consequences for workers and clients/customers. Three examples are taken from professions involving long-term relations between workers and clients. Adult education teachers hired on short-term contracts to teach primarily immigrant populations prepare their courses under less favorable conditions than regular teachers and their employment context foments hostility among teachers. Special education technicians are hired on a seasonal basis which interferes with their ability to coordinate and plan their efforts in collaboration with teachers. Workers in shelters for women suffering conjugal violence who were hired on a casual or on-call basis were unable to follow up with women they helped during their shifts and more rarely engaged in one-on-one counseling. Precarious work contracts can affect mental health not only through employment insecurity but also through negative effects on the ability to do one's job and take pride in one's work, as well as weakening the interpersonal relationships on which successful, productive work depends.     

Heteroplasmy in hair: differences among hair and blood from the same individuals are still a matter of debate

The analysis of mitochondrial DNA (mtDNA) is a useful tool in forensic cases when sample contents too little or degraded nuclear DNA to genotype by autosomal short tandem repeat (STR) loci, but it is especially useful when the only forensic evidence is a hair shaft. Several authors have related differences in mtDNA from different tissues within the same individual, with high frequency of heteroplasmic variants in hair, as also in some other tissues. Is still a matter of debate how the differences influence the interpretation forensic protocols. One difference between two samples supposed to be originated from the same individual are related to an inconclusive result, but depending on the tissue and the position of the difference it should have a different interpretation, based on mutation-rate heterogeneity of mtDNA. In order to investigate it differences in the mtDNA control region from hair shafts and blood in our population, sequences from the hypervariable regions 1 and 2 (HV1 and HV2) from 100 Brazilian unrelated individuals were compared. The frequency of point heteroplasmy observed in hair was 10.5% by sequencing. Our study confirms the results related by other authors that concluded that small differences within tissues should be interpreted with caution especially when analyzing hair samples.
