Unusual association of three rare alleles and a mismatch in a case of paternity testing

This study reports a paternity case analyzed by the AmpFlSTR Identifiler Kit (AB) in which father and daughter shared three rare alleles for D19S433, D18S51 and TH01 microsatellites. The case also showed an apparent exclusion, due to a mutation at the D3S 1358 microsatellite. Sequencing analysis was performed to assess the size of the rare alleles and to establish their structure, which revealed some molecular variations in regions flanking the motif repeats.     

A quantitative differentiation method for acrylic fibers by infrared spectroscopy

Absorbance peak areas of nitrile (2240 cm(-1)), carbonyl (1730 cm(-1)) and CH (1370 cm(-1)) groups were obtained for 48 colorless acrylic fibers by infrared (IR) microspectroscopy. The carbonyl signal, related to the comonomers most commonly used in acrylic fibers, was ratioed against the nitrile and CH bands, pertaining to the backbone of the polymer chains. The ratios A1730/A2240 and A1730/A1370, a relative measure of the comonomer content in the fiber, were used to differentiate the samples. A decrease in the crystallinity of fibers has been noted with increasing comonomer content. Relative standard deviation (R.S.D.) of the ratios were 1 and 3% for repetitive analyses on the same location and along the length of the same single fiber, respectively. When different fibers of the same sample were examined, results were reproducible within 6%. This simple method can greatly enhance the evidential value of colorless acrylic fibers, being able to discriminate them and thus helping the Court to better assess their significance.     

Parenting,Peer Orientation,Drug Use,and Antisocial Behavior in Late Adolescence: A Cross-National Study

The objective of this study was to investigate the links between maternal and paternal bonding, parental practices, orientation toward peers, and the prevalence of drug use and antisocial behavior during late adolescence. A model was tested using structural equation modeling in order to verify the robustness of the investigated links across 3 countries: Canada, France, and Italy. A self-report questionnaire was given to a sample of 908 adolescents, with an equivalent number of girls and boys, in Grade 11. The questionnaire assessed the following variables: parental bonding, parental supervision, parental tolerance, orientation toward peers, involvement in physically aggressive antisocial behavior, non-physically aggressive antisocial behavior, and drug use. The model was robust across the 3 countries, thus confirming a path that identified quality of emotional bonds between adolescents and their parents as a distal variable acting upon deviant behaviors through the following mediators: parental supervision, parental tolerance, frequency of conflicts, and orientation toward peers. Michel Claes is full professor at the Université de Montréal, Canada. He received his Ph.D. in Education from Université Catholique de Louvain, Belgium. His major research interest is in social development in adolescence, with a special focus on intercultural studies.     

Longing for the past: a semiotic reading of the role of nostalgia in present-day consumption trends

Coined in 1688 by Swiss physician Johannes Hofer to designate a pathological longing for distant homeland, the word “nostalgia” was soon rearticulated temporally, to refer to a lost epoch one yearns for as one's home. Nostalgia is not a new topic for semiotics. Emotion essentially stemming from absence, it epitomizes the semiotic mechanism: semiosis is the ontological result of something staying for something else, but nostalgia is the emotional result of it. Nostalgia – an essential figure in Greimas's structural outlook on passion, an umbrella concept in Baudrillard's mourning of reality behind the simulacra, and a key notion in Culler's and Frow's dissection of the semiotics of tourism – has become a buzz word in both critical and marketing studies, the former trying to unveil beneath it the foundations of ontology or the contradictions of postmodern society and the latter, seeking to exploit nostalgia as what critical theory could deem the last Trojan horse into the agency of the consumer. On the basis of a copious and manifold literature on nostalgia, the article hints at an unexplored direction: can one talk, today, of nostalgic trends of consumption in Europe? Where hipsters, vintage furniture, and retro TV channels are nothing but symptoms of an emerging mentality?     

To be or not to be Charlie Hebdo: ritual patterns of opinion formation in the social networks

The social sciences have mostly focused on the formation of social opinions from a semantic point of view: given a certain semantic field, interviews, statistics, and other analytical instruments are commonly deployed in order to map the distribution of views, their evolution, their conflicts and their agreements. Socio-semiotics, social semiotics, and the other semiotic branches that bear on social inquiry have contributed to the effort by providing semiotic grids of categorization. These grids too, however, have been mostly related to semantic contents circulating through societies and their cultures. The present article pursues a different hypothesis. After briefly recalling the events of 7–9 January 2015 in the Parisian area, the article seeks to survey and map the syntax of progressive differentiation of opinions circulating in the social networks about such events. Some patterns are identified and semiotically described: (1) cleavage; (2) comparative relativizing; (3) blurring sarcasm; (4) anonymity; (5) unfocused responsibility; (6) conspiracy thought. A new semiotic square is created to visually display these patterns, their positions, their relations, and their evolution.
