Electrochemical ecology: VIMP monitoring of plant defense against external stressors
2015
The use of the voltammetry of immobilized particles (VIMP) approach, by means of the voltammetric response of microparticulate films from ethanolic leaf extracts in contact with aqueous electrolytes and direct contact probe leaf voltammetry, to monitor the defense of plants against external stressors is described. This approach is applied to study the chemical communication between plants of Peperomia obtusifolia A. Dietr. submitted to herbivory by the beetle Monoplatus sp.

Carbohydrates in plant immunity and plant protection: roles and potential application as foliar sprays.
2014
International audience; Increasing interest is devoted to carbohydrates for their roles in plant immunity. Some of them are elicitors of plant defenses whereas other ones act as signaling molecules in a manner similar to phytohormones. This review first describes the main classes of carbohydrates associated to plant immunity, their role and mode of action. More precisely, the state of the art about perception of "PAMP, MAMP, and DAMP (Pathogen-, Microbe-, Damage-Associated Molecular Patterns) type" oligosaccharides is presented and examples of induced defense events are provided. A particular attention is paid to the structure/activity relationships of these compounds. The role of sugars as…
Cuando la historia está presente: Argumentos a favor de la sociología histórica
2019
Sociology and history have maintained a discontinuous relationship and a permanent discussion. Classical sociology is intrinsically historical, but after the first theoretical synthesis the dialogue between both disciplines was extinguished and it has often been necessary to defend the need for the historical view in sociology from the margins of the dominant paradigm. However, as a specialty or subdiscipline, historical sociology has consolidated its own academic space and a strong theoretical, methodological and conceptual body. In Spain this process of institutionalization has not yet success. In this article we expose a few arguments in defense of historical sociology, both theoretical …
Effect of inter-individual variability and intraguild interferences on the foraging strategies of seed-eating carabid species
2017
Making a choice requires, implicitly, an investment of time in one behaviour at the expense of an investment in another. Being choosy would increase the risk of losing many food item opportunities to competitors, and is directly in conflict with other essential tasks such as predator avoidance. Individuals are thus expected to adjust their level of choosiness in response to the competition and predation context. The available behavioural ecological theory and the empirical ecology of carabids would suggest that competition and predation interference induces changes in the foraging behaviour of carabid individuals. Carabids typically operate within communities in which competition and predat…
Protecting the besieged cyber fortress : Russia’s response to cyber threats
2019
The Information Security Doctrine of the Russian Federation (RF) defines the threat to information security as a complex of actions and factors that represent a danger to Russia in the information space. These threats can be information-psychological (i.e., when the adversary tries to influence a person’s mind) or information-technical (i.e., when the object of influence is the information infrastructure). The information infrastructure of the RF is a combination of information systems, websites, and communication networks located in the territory of the RF, or those used as part of international treaties signed by the RF. A cyber threat is an illegal penetration or threat of penetration by…
Il defense mechanisms inventory
2015
Il Defense Mechanisms Inventory (DMI) (Gleser e Ihilevich, 1969; Gleser e Ihilevich, 1986) è un questionario semiproiettivo per la valutazione degli stili difensivi. Creato alla fine degli anni sessanta da Gleser e Ihilevich, si è diffuso nella pratica clinica e nella ricerca, godendo di buona considerazione nella letteratura scientifica (Davidson e McGregor, 1998). Soltanto la forma per adulti è stata validata in Italia, ma esistono sia la forma per adolescenti sia quella per anziani. La forma per adolescenti prevede una versione breve risultata piuttosto affidabile sia nella clinica sia nelal ricerca (Recklitis et al. 1995).
Orthorexic tendencies and healthy eating in university students: which association with eating disorders, psychopathology, and defense mechanisms?
2021
Orthorexic tendencies and healthy eating in university students: which association with eating disorders, psychopathology, and defense mechanisms? higher in some immature defenses (passive aggression and somatization) than healthy-eating individuals, while no differences were found in mature and neurotic defense styles. Conclusions. These results support the existence of significant differences between ON and other (non-problematic) healthy eating behaviors.

Opolskie manifestacje w obronie demokracji
2021
Opole is a provincial city of the smallest region in the country. Nevertheless, its inhabitants manifest their views on matters important from their point of view. The analysis of the largest protests in re- cent years in this region shows that the inhabitants of Opole most often and loudly demonstrate in de- fense of democracy — both at the national and local level. In the chapter Opole demonstrations in de- fense of democracy, Katarzyna Daniel proposes an analysis of two problems that caused Opole inhab- itants to take to the streets, i.e. protests in defense of the broadly understood judiciary initiated in 2017 and demonstrations and strikes caused by the en- largement of the administrat…
