House money effects on trust and reciprocity

In a typical laboratory “Investment Game” experiment, participants’ endowments are provided by the experimenter; thus, the worst case for the investor is that she loses all of her “found” money. By contrast, in naturally occurring environments, investment decisions can often lead to a loss of one’s own money. This paper investigates whether “trust” found in one-shot anonymous laboratory interaction is robust to “own money” environments. Our results show that, consistent with previous investment game results, most investors send a positive amount, and most trustees return at least the transfer amount, regardless of whether the investors purchase or are gifted their endowment. However, investments are on average lower when participants use their own money, and the fraction of maximum investments (the most “risky” investment decision) is only half as large under “own money” as it is under gifted endowments. Our results explain why one should exercise caution in placing trust in any government’s ability to spend other people’s money prudently.     

Xenophobic Rhetoric and Its Political Effects on Immigrants and Their Co‐Ethnics

Though political scientists generally understand the origins of native‐born reactions to foreigners, less is known about how anti‐immigrant contexts trigger a political response within immigrant groups. I address this question by studying the connection between xenophobic rhetoric and Latino politics. I claim that xenophobic rhetoric raises the salience of ethnic identity and impugns its worth. This identity threat leads high‐identifying group members to engage in political efforts that assert their group's positive value, whereas low identifiers shun political opportunities to bolster their group's devaluation. I test these claims with an experiment embedded in a nationally representative opinion survey of Latino adults. In light of xenophobic rhetoric, I find that relative to low identifiers, high‐identifying Latinos become less politically trusting, more ethnocentric, and increasingly supportive of policies that emphasize ingroup pride. These results clarify xenophobic rhetoric's role in amplifying the influence of ethnic identity on immigrant politics.     

Nondestructive Methods for Recovery of Biological Material from Human Teeth for DNA Extraction

The extraction of DNA from human skeletal remains applied to forensic, and evolutionary studies do not exclude risks, which are to be evaluated when working with unique specimens that could be damaged or even destroyed. In the present study were evaluated several nondestructive methods for recovering DNA instead of the most currently used pulverization method. Three different procedures to access inside the dental pieces (occlusal perforation, cervical perforation, and cervical cut) have been compared with the aim of recovering as many cell remains as possible to carry out a DNA extraction. Given the DNA quantitation results, a method was proposed that consists of a cervical cut to facilitate the access to the pulp cavity and a subsequent filing of the root canals down to the apex of the dental root. This methodology allows the recovery of both mitochondrial and nuclear DNA, with the minimum deterioration for the dental pieces.     

Animal Scavenging and Scattering and the Implications for Documenting the Deaths of Undocumented Border Crossers in the Sonoran Desert,

Since 1998, over 5500 people have died while attempting to cross the U.S.–Mexico border without authorization. These deaths have primarily occured in the Arizona desert. Despite the high volume of deaths, little experimental work has been conducted on Sonoran Desert taphonomy. In this study, pig carcasses were used as proxies for human remains and placed in different depositional contexts (i.e., direct sunlight and shade) that replicate typical sites of migrant death. Decomposition was documented through daily site visits, motion-sensitive cameras and GIS mapping, while skeletal preservation was investigated through the collection of the remains and subsequent faunal analysis. Our results suggest that vultures and domestic dogs are underappreciated members of the Sonoran scavenging guild and may disperse skeletal remains and migrant possessions over 25 m from the site of death. The impact of scavengers and the desert environment on the decomposition process has significant implications for estimating death rates and identifying human remains along the Arizona/Mexico border.     

Differences in Handwritings of Schizophrenia Patients and Examination of the Change after Treatment

The aim of this study was to analyze the differences between the handwritings of schizophrenia patients and healthy subjects in addition to the changes that occurred in schizophrenia patients' handwriting in response to the treatment. The test subjects were 29 schizophrenia patients and 29 healthy individuals with the same age, gender, and dominant hand. The changes in the handwritings were examined according to 14 different parameters. On the day of admittance, the percentage of extra letters was 16.7%, and after 7–10 days of hospitalization, it rose to 33.3%. The percentage of skipped words decreased from 29.2% to 16.7% after 7–10 days of hospitalization, and to 10% after 3 weeks. The letters written by schizophrenia patients are significantly larger in height and width compared to the control group. The schizophrenia patients showed a higher incidence of crossed-out letters, adding extra words, missing punctuation as well as missing words.     

Regulating forced labour and combating human trafficking: the relevance of historical definitions in a contemporary perspective

Forced labour has been regulated since 1930 on the basis of the ILO Convention on Forced Labour, and since 1957 on the basis of the ILO Abolition of Forced Labour Convention. In 2000 forced labour was included as one form of exploitation covered by the UN Trafficking Protocol, which situated trafficking into a context of transnational organised crime. In 2014 the ILO adopted a Protocol on Forced Labour, making a link between trafficking and forced labour. The aim of this article is to explore how forced labour came to be regulated and defined in these four treaties. The 1930 ILO Convention came about in a specific historical and political context, yet the 1930 definition remains in use even though the interpretation of forced labour, particularly as it relates to trafficking, has changed. This article focuses on the issue of trafficking for the purpose of forced labour within the context of migration and labour exploitation, and discusses the relevance of historical definitions of forced labour in the current discourse that sees human trafficking mainly as a security threat. It argues that a rigid interpretation of forced labour is not always useful in understanding forms of labour exploitation, at least in a contemporary European migratory perspective. The article calls for a broad interpretation of forced labour, which takes into account also subtle forms of control and coercion.
