Choking death on a live fish (Dicologoglossa cuneata)

A choking death of a healthy fisherman, who put a type of live sole between his jaws to free up his hands so that he could collect more fish to put into his basket, is described. The fish squirmed into the larynx and upper trachea and the attempts to rescue the man by his colleagues who used pliers did not succeed, and the man died. Other published cases are reviewed, and risk factors and rescue possibilities discussed.     

Objective measurement of dental color for age estimation by spectroradiometry

Age-related changes in tooth color have been described previously, however, the use of dental color for age estimation in forensic odontology has been limited due to the difficulty of measuring color objectively. This study presents an objective method for determining dental color to estimate the age of an individual. Dentine color in 250 teeth from patients ranging in age from 10 to 89 years was determined by spectroradiometry. Color measurements were performed as suggested in the CIE 1931 (International Commission on Illumination). Chromaticity coordinates (x, y, z), luminance (Y), whiteness index (WIC, Z%, WIC) and yellowness index (YI) were obtained. Correlations between these colorimetric variables and aging were established by linear regression analyses. All the variables fit the mathematical model with correlation coefficients ranging from 0.53 to 0.75. This method of color measurement produced an expected associated error of calibration averaging 13.7 years about the mean estimated values, at a 70% level of confidence. Two different multiple regression models for dental age estimation were tested, and variables that made the greatest contributions to age calculation were identified. To determine the effect of postmortem interval on tooth color and its influence in age estimation, 37 teeth obtained from human skeletal remains buried during an interval ranging from 21 to 37 years were also studied. In this material, the correlation between age and dental color measured by spectroradiometry was weaker than in fresh extracted teeth.It is concluded that determination of dentine color by spectroradiometry is a potentially useful objective method to estimate age in forensic studies in combination with other methods.     

The 2000-2001 GEP-ISFG Collaborative Exercise on mtDNA: assessing the cause of unsuccessful mtDNA PCR amplification of hair shaft samples

We report the results of Spanish and Portuguese working group (GEP) of International Society of Forensic Genetics (ISFG) Collaborative Exercise 2001-2002 on mitochondrial DNA (mtDNA) analysis. 64 laboratories from Spain, Portugal and several Latin-American countries participated in this quality control exercise. Five samples were sent to the participating laboratories, four blood stains (M1-M4) and a sample (M5) consisting of two hair shaft fragments. M4 was non-human (Felis catus) in origin; therefore, the capacity of the labs to identify the biological source of this sample was an integral part of the exercise. Some labs detected the non-human origin of M4 by carrying out immuno-diffussion techniques using antihuman serum, whereas others identified the specific animal origin by testing the sample against a set of animal antibodies or by means of the analysis of mtDNA regions (Cyt-b, 12S, and 16S genes). The results of the other three human blood stains (M1-M3) improved in relation to the last Collaborative Exercises but those related to hairs yielded a low rate of success which clearly contrasts with previous results. As a consequence of this, some labs performed additional analysis showing that the origin of this low efficiency was not the presence of inhibitors, but the low quantity of DNA present in these specific hair samples and the degradation.As a general conclusion the results emphasize the need of external proficiency testing as part of the accreditation procedure for the labs performing mtDNA analysis in forensic casework.     

Results of the GEP-ISFG collaborative study on the Y chromosome STRs GATA A10, GATA C4, GATA H4, DYS437, DYS438, DYS439, DYS460 and DYS461: population data

The Spanish and Portuguese ISFG Working Group (GEP-ISFG) carried out a collaborative exercise in order to asses the performance of two Y chromosome STR tetraplexes, which include the loci DYS461, GATA C4, DYS437 and DYS438 (GEPY I), and DYS460, GATA A10, GATA H4 and DYS439 (GEPY II). The groups that reported correct results in all the systems were also asked to analyse a population sample in order to evaluate the informative content of these STRs in different populations. A total of 1020 males out of 13 population samples from Argentina, Brazil, Costa Rica, Macao, Mozambique, Portugal and Spain were analysed for all the loci included in the present study. Haplotype and allele frequencies of these eight Y-STRs were estimated in all samples. The lowest haplotype diversity was found in the Lara (Argentina) population (95.44%) and the highest (99.90%) in Macao (China). Pairwise haplotype analysis showed the relative homogeneity of the Iberian origin samples, in accordance with what was previously found in the European populations for other Y-STR haplotypes (http://www.ystr.org). As expected, the four non-Caucasian samples, Macao (Chinese), Mozambique (Africans), Costa Rica (Africans) and Argentina (Lara, Amerindians), show highly significant Phist values in the pairwise comparisons with all the Caucasian samples.     

Candidate competition and strategic coordination: evidence from four early Norwegian elections

This article investigates strategic coordination in four elections to the Norwegian Storting (1909–18). The elections were held under a majority-plurality dual-ballot system, with unrestricted participation in the second-ballot. The focus is on elections with Conservative, Liberal and Labour candidates as main contenders. Supported by historical and theoretical arguments, the authors assume universally sincere voting in the first-ballot. Given this assumption, second-ballot elections can be analyzed as regular plurality elections. Hypotheses about behavior are formed using the game theoretic framework of Myerson and Weber (American Political Science Review 87 (1993) 102–114). It is found that while voters follow the predictions of theory fairly closely, the extent of coordination present at the candidate level can be questioned.     

Seeking forgiveness in an intergroup context: Angolan,Guinean, Mozambican,and East Timorese perspectives

Forgiveness is a key concept in many governance and responsive regulation issues. The notion of intergroup forgiveness was examined among people from four countries: Angola, Guinea‐Bissau, Mozambique, and East Timor. Nine hundred and eighty‐five adults who had suffered from the many conflicts in their areas, either personally or through injuries inflicted on members of their family, agreed to participate in a study that was specifically about seeking intergroup forgiveness. In all four countries, most participants of the study agreed with the ideas that (i) seeking intergroup forgiveness makes sense; (ii) the seeking process must be a popular, democratic, and public process, not a secret elite negotiation; (iii) the process must be initiated and conducted by people in charge politically, not by dissident factions; and (iv) the process is aimed at reconciliation, not at humiliating the group requesting forgiveness. Differences between the four countries were found regarding the extent to which (i) international organizations may be involved in the process; (ii) the demand must include the former perpetrators; and (iii) emotions and material compensation are ingredients in the process.     

Informal helping networks in prison: The shape of grass-roots correctional intervention

Factors related to the delivery of human services to prisoners with problems and crises of adjustment were explored in this study. Emphasis was placed on describing the human service roles played by custodial and treatment staff, particularly among staff members who took it upon themselves to (a) expand their formal organizational roles to include a general mandate to identify and assist inmates with problems, and (b) work cooperatively with similarly motivated staff as more or less stable members of informal helping networks or teams. Interview data were used to reconstruct the parameters of informal helping networks, to identify factors that facilitated or inhibited their development, and to obtain indications of their usefulness in the helping process. The research findings suggest more efficient ways to deploy existing correctional resources in the delivery of human services to prisoners. The study also highlights issues of correctional resource deployment that may bear on the larger problem of cultivating human environments in which rehabilitation or planned change can occur.     

Internet voting and the secret ballot in Norway: principles and popular understandings

The secret ballot is considered a central feature of democratic elections, but its practical implications may be contested when Internet voting (and remote voting in general) is introduced. How do citizens understand the principle of the secret ballot in practice? The issue was brought to the fore in a trial with Internet voting that was conducted in 12 Norwegian municipalities for the 2013 parliamentary election. Based on a representative population survey, we explore how Norwegian voters approached the principle of the secret ballot in the context of Internet voting. A large majority supported the general principle, but the picture became more nuanced when it was put to the test of concrete situations. Unless the situation involved coercion or undue influence, many people were willing to accept that voting can be observed by others – even if this was a breach of legal regulations.
