A multi-level approach to the analysis of narrative language in aphasia
Andrea Marini, Sara Andreetta, Silvana Del Tin, Sergio Carlomagno, 2011, original scientific article

Abstract: Several studies have shown that traditional standardised aphasia tests may not be sensitive enough to adequately assess linguistic deficits and recovery patterns in persons with aphasia. As a result, both functional and structural methods for the ana- lysis of connected language samples from people with aphasia have been devised (see Armstrong, 2000; Prins & Bastiaanse, 2004). The present article focuses on our attempt to provide a comprehensive, multi-level procedure for both structural and functional analysis of narrative discourse produced by speakers with brain damage. Accordingly, we will describe a method for analysis of connected language samples elicited on single picture and cartoon story description tasks. This method has proven sensitive in the assessment of language deficits in many neurogenic populations. A comprehensive description of the language production sys- tem, a thorough discussion of the different approaches to discourse analysis in persons with aphasia, and the procedure for the analysis of narrative discourse are detailed. The characteristics of the eliciting stimuli, the procedures for their administration and the transcription of the language samples are carefully explained. The analysis focuses on four main aspects of linguistic processing: productivity, lexical and grammatical pro- cessing, narrative organisation, and informativeness. To further illustrate the analytic procedure, two case reports and an appendix with the analysis of a narrative sample are provided. We will provide direct evidence of the usefulness of the multi-level procedure for discourse analysis for assessing changes in discourse performance of two persons with fluent aphasia, with different aetiologies, that were not captured by tradi- tional standardised aphasia tests. The method of analysis presented in this paper has strong grounds in linguistic and psychological theories of linguistic structure and functioning. It also has the advantage of being both quantitative and functional as it captures selective aspects of linguistic processing, and can provide relevant information about the person's communicative and informative skills.

Use of hair cortisol analysis for comparing population status in wild red deer (Cervus elaphus) living in areas with different characteristics
Luca Pedrotti, Alberto Prandi, Tanja Peric, Antonella Comin, Chiara Caslini, Silvana Mattiello, 2016, original scientific article

Abstract: We tested a method to measure Hair Cortisol Concentration (HCC) in 174 red deer (Cervus elaphus) culled in the hunting season 2011/12 in four areas of Central Italian Alps, with different population densities (SPN, 11.8 deer/km2; HD-AV, 3.6 deer/km2; HD-SO, 2.1 deer/km2; HD-MO, 2.0 deer/km2) and environmental conditions. Our hypothesis was that higher population densities, associated with more difficult environmental conditions, may result in higher allostatic load for these wild ungulates. No significant differences in HCC were detected between sexes (males, 4.77 ± 0.69 pg/mg; females, 5.75 ± 0.63 pg/mg) nor among age classes (calves, 6.17 ± 0.66 pg/mg; yearlings, 4.47 ± 0.83 pg/mg; adults, 5.15 ± 0.74 pg/mg; least square mean ± SE), but HCC difference between calves and yearlings was close to statistical significance (P = 0.059). HCC showed high individual variation, but on average it was higher in areas with higher deer density (SNP, 7.45 ± 1.01 pg/mg; HD-AV, 6.07 ± 0.89 pg/mg; HD-SO, 4.67 ± 1.14 pg/mg; HD-MO, 2.87 ± 1.56 pg/mg), with significant differences between HD-AV and HD-MO (P = 0.01). Carcass weight was significantly lower in SNP (46.74 ± 1.49 kg) than in HD-MO (62.71 ± 4.01 kg), HD-SO (61.73 ± 2.9 kg) and HD-AV (62.07 ± 2.04 kg) (P < 0.001). These results seem to confirm our hypothesis that allostatic load is higher in areas with higher density and harder environmental conditions. We suggest that the methodology used in this study to measure HCC provides good information on long-term HPA axis activity and allostatic load and constitutes a highly promising, reliable and non-invasive method in wildlife management for assessing HPA axis activity over extended time periods.
