Abstract: towing gears are known to produce several kinds of effects on benthic ecosystems. as small organisms and benthic species with faster growth rates and shorter life histories can withstand the fishing mortality and benefit from reduced competition or predation, trawl fishing can enhance their proliferation. thus, trawl fishing can lead to biomass loss and production increase, since smaller specimens are more productive than bigger ones. in the present study we evaluate the effects, if any, of trawling on benthic crustacean macrofaunal production rates. sampling was carried out in two neighbouring sites in the central adriatic sea (central mediterranean), one affected by fishing activity and one not. production and production/biomass (p/b) ratio of 13 species of peracarid and eucarid crustaceans were estimated using the hynes size-frequency method. estimates measured at both sites were compared in order to test the hypothesis that higher production and p/b values should occur in the fished area rather than in the unfished one. our results indicated that the effects on the species are more complex than expected in regard to this hypothesis, and that they depend on the ecological and behavioural characteristics of the selected species.
Technical Note: The air quality modeling system Polyphemus
V. Mallet,D. Quélo,B. Sportisse,M. Ahmed de Biasi
Atmospheric Chemistry and Physics Discussions , 2007,
Abstract: Polyphemus is an air quality modeling platform which aims at covering the scope and the abilities of modern air quality systems. It deals with applications from local scale to continental scale, using two Gaussian models and two Eulerian models. It manages passive tracers, radioactive decay, photochemistry and aerosol dynamics. The structure of the system includes four independent levels with data management, physical parameterizations, numerical solvers and high-level methods such as data assimilation. This enables sensitivity and uncertainty analysis, primarily through multimodel approaches. On top of the models, drivers implement advanced methods such as model coupling or data assimilation.

Trace Eyeblink Conditioning is Impaired in α7 but not in β2 Nicotinic Acetylcholine Receptor Knockout Mice

Frontiers in Behavioral Neuroscience , 2010, DOI: 10.3389/fnbeh.2010.00166
Abstract: Nicotinic acetylcholine receptors (nAChRs) are essentially involved in learning and memory. A neurobiologically and behaviorally well-characterized measure of learning and memory, eyeblink classical conditioning, is sensitive to disruptions in acetylcholine neurotransmission. The two most common forms of eyeblink classical conditioning – the delay and trace paradigms – differentially engage forebrain areas densely-populated with nAChRs. The present study used genetically modified mice to investigate the effects of selective nAChR subunit deletion on delay and trace eyeblink classical conditioning. α7 and β2 nAChR subunit knockout (KO) mice and their wild-type littermates were trained for 10 daily sessions in a 500-ms delay or 500-ms trace eyeblink conditioning task, matched for the interstimulus interval between conditioned stimulus and unconditioned stimulus onset. Impairments in conditioned responding were found in α7 KO mice trained in trace – but not delay – eyeblink conditioning. Relative to littermate controls, β2 KO mice were unimpaired in the trace task but displayed higher levels of conditioned responding in delay eyeblink conditioning. Elevated conditioned response levels in delay-conditioned β2 KOs corresponded to elevated levels of alpha responding in this group. These findings suggest that α7 nAChRs play a role in normal acquisition of 500 ms trace eyeblink classical conditioning in mice. The prominent distribution of α7 nAChRs in the hippocampus and other forebrain regions may account for these genotype-specific acquisition effects in this hippocampus-dependent trace paradigm.
The “Colour Family Drawing Test”: A Comparison between Children of “Harmonious” or “Very Conflictual Families”  [PDF]

Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.519212
Abstract: The “Colour Family Drawing Test” applied a classification of colours on an emotional basis leading to the distinction between “Alarming and Serious” (black, grey, violet, olive-green, dark blue, red, yellow) and “Reassuring and Playful” hues (pink, sky blue, orange and pastel colours). 120 participants (aged 7 - 10 years, both genders), attending Rome primary schools, were individually examined. They sat at a table with a white A4 card, 24 colour pencils, a black pencil, an eraser and received the instruction: “Draw your family”. The research objective concerns the introduction of colours and the evaluation of emotional meaning of the colours used by children in drawing their families. The families had been preliminarily evaluated as Harmonious or Very Conflictual Families through a semi-structural interview conducted with the children’s teachers. The drawings made by children of Harmonious Families consistently used reassuring, playful colours (p < 0.01); children of Conflictual Families used alarming, serious colours (p < 0.01). The parents also compiled the LDM Inventory, in order to have a confirmation of their level of psychological conflict. 33 “Very harmonious” parents and 22 “Very Conflictual” parents were selected. A comparison revealed that N/H scores were significantly lower in parents of Very Conflictual Families compared to the opposite ones (t53 = 2.95; p < 0.01). Conflictual Parents do not develop harmonious interpersonal relations, preferring overt aggression, with particular consequences for the family’s emotional atmosphere and for the children’s personality.
Relation between Stress Conditions, Uncertainty and Incongruity Intolerance, Rigidity and Mental Health: Experimental Demonstrations  [PDF]

Abstract: An innovative critique of existing studies on creativity has revealed the opportunity of distinguishing between different varieties of creative tasks, and namely creativity for “Continuity”, “Opposition” and “Detachment”, considering relations between products and perceived models. This theoretical contribution has led to a specific evaluation procedure: the COD Creativity test. Considering the influences of dynamic processes on creative processes, it is worth experimentally studying the effects of short-term stress or comfort treatments. The similarities and differences between various existing studies are examined. A non-invasive but effective procedure, compared to classic techniques, is described: the “drawing recall” of stressful or relaxing real experiences, accompanied by detailed evaluations of the emotional sphere. In a specific investigation, creativity turned out to be significantly lower after acute stress with respect to comfort treatment. In conclusion, the cognitive, decisional and activity processes involved in creativity operations can be considered as strictly reflecting emotional dynamic processes, as well as the experiences gained during the stress or comfort treatments. Results are explained considering the role of conflict overload in stress as a factor of incongruity and uncertainty intolerance, inhibiting the production of bizarre and unusual ideas and configurations, and thus reducing essential aspects relevant to the evaluation of creativity levels. From clinical point of view, we underline that decades of research has generally shown that being more rigid is associated with poorer mental health. Our experimental study gives confirmation of the link between stress and intolerance of uncertainty and incongruity; this correlation could augment the negative impact of stressors on anxiety levels. In summary, people with high level of intolerance of uncertainty and, generally, with high level of intolerance of incongruity, develop mental rigidity, and this traits constellation represent a risk for mental health.
The “Colour Family Drawing Test”: Assessing Children’s Perception of Family Relationships. Studies on Mental Health and Cross-Cultural Comparisons  [PDF]

Health (Health) , 2015, DOI: 10.4236/health.2015.73034
Abstract: We apply the Colour Family Drawing Test, as a development of the traditional black and white test, for cross-cultural comparison. The participants, aged 7 - 10 years, both genders, were examined individually. Each subject sat at a single table with a white rectangular card of standard size, 24 well-sharpened colour pencils, a black pencil, an eraser and other appropriate tools. S/he received this verbal instruction: “Draw your family”. The procedure was firstly applied to 120 participants attending primary schools of Rome (Biasi, Bonaiuto and Levin, 2014). The families were evaluated through a semi-structural interview conducted with the children’s teachers and divided into: Harmonious versus Very Conflictual Families. The drawings made by children of Harmonious Families consistently used “Reassuring and Playful Colours” (Pink, Orange, Sky Blue, Light Green, Light Yellow, other pastel colours); and were larger, tidier and more proportioned to respect the opposite group. Children belonging to Conflictual Families used mostly “Alarming and Serious Colours” (Grey, Black, Dark Bleu, Violet, Olive Green) and their drawings were less extended, more often disordered and had typical deformations such as figures too thin. A second investigation examined 120 participants belonging to Asian immigrant families residing in Italy. A third investigation examined 120 participants belonging to Russian families of Moscow. Both last two investigations obtained very similar results on the use of colours, and gave a confirmation of the relevance of the Colour Family Drawing Test.
