Resilience of Mediterranean Forests to Climate Change
2017
In the Mediterranean region, forests play a key role in the welfare of urban and rural peoples, by providing highly appreciated marketed goods as well as high value but nonmarket services. Anthropogenic climate change entails a significant impact on Mediterranean forests, such as the reduced species diversity, high density, pest, and diseases. In this chapter, we present the achievements of the project LIFE ResilForMed (Resilience of Mediterranean Forests to climate change), as Sicilian responds on adaptation and mitigation to climate change: (i) map of Sensitivity Forest Areas to desertification of the Sicilian region; (ii) list of bird indicators showing sensitivity to desertification in …
TEACHERS' SOCIAL AND EMOTIONAL HEALTH INDICATORS IN THE DISTANCE LEARNING SITUATION DURING THE COVID-19 PANDEMIC
2021
There were 3 countries which participated in Erasmus+ project „Supporting teachers to face the challenge of distance teaching” (2020-1-LV01-KA226-SCH-094599) during last year. The aim of the project was to develop a well-functioning digital support system for teachers, promoting socio-emotional health and resilience. The main aim of this research was to outline a research problem on teacher well-being factors in three countries during the Covid-19 pandemic, when teachers worked remotely, and to further explore the problem in a focus group in Latvia. The following is a description of the study that was carried out in Latvia on the problems of teachers' social and emotional health factors dur…
Unraveling assemblage, functions and stability of the gut microbiota of Blattella germanica by antibiotic treatment
2020
Symbiosis between prokaryotes and eukaryotes is a widespread phenomenon that has contributed to the evolution of eukaryotes. In cockroaches, two types of symbionts coexist: an endosymbiont in the fat body (Blattabacterium), and a rich gut microbiota. The transmission mode of Blattabacterium is vertical, while the gut microbiota of a new generation is mainly formed by bacterial species present in feces. We have carried out a metagenomic analysis of Blattella germanica populations, treated and non-treated with two antibiotics (vancomycin and ampicillin) over two generations to (1) determine the core of bacterial communities and potential functions of the gut microbiota and (2) to gain insight…
Testing the H.264 error-resilience on wireless ad-hoc networks
2004
The purpose of this paper is to provide a framework to tune and evaluate the performance of the H.264 codec in 802.11b wireless ad-hoc networks. The codec's error-resilience features are measured under stress conditions typical to these networks, and the most critical parameters are presented. We present solutions concerning the random packet loss problem and show how to quickly recover from packet loss bursts.
An efficient Chinese remainder theorem based node capture resilience scheme for Mobile WSNs
2010
Node capture attack is a critical issue in Mobile WSNs where attacker-controlled replicas may act maliciously. In this paper, we present a novel Chinese remainder theorem based node capture resilience scheme that can be utilized to discover and revoke captured nodes. Moreover, our scheme can limit the ability of captured nodes to further compromise forward security, backward security, and launch collusion attacks. Detailed analysis shows that our scheme indeed achieves the expected design goals.
Strengthening global health security by embedding the International Health Regulations requirements into national health systems
2018
The International Health Regulations (IHR) 2005, as the overarching instrument for global health security, are designed to prevent and cope with major international public health threats. But poor implementation in countries hampers their effectiveness. In the wake of a number of major international health crises, such as the 2014 Ebola and 2016 Zika outbreaks, and the findings of a number of high-level assessments of the global response to these crises, it has become clear that there is a need for more joined-up thinking between health system strengthening activities and health security efforts for prevention, alert and response. WHO is working directly with its Member States to promote th…
Information in the aspect of security threats and challenges
2019
INFORMATION IN THE ASPECT OF SECURITY THREATS AND CHALLENGESIn the article, the author describes the driving force behind deliberate informational activities. He pays particular attention to the current security situation in the information dimension. Existing systems in the area of security management should be resistant to disinformation and informational operations. There is no room for the freedom of interpretation of the information acquired since every decision results in the actions of people, therefore it requires accuracy and caution. This issue takes on a special dimension when it concerns the state, because this environment contains specific features such as a changing environmen…
Don’t Stress, It’s Under Control: Neural Correlates of Stressor Controllability in Humans
2021
AbstractAnimal research has repeatedly shown that experience of control over an aversive event can protect against the negative consequences of later uncontrollable stress. Neurobiologically, this effect is assumed to correspond to persistent changes in the pathway linking the ventromedial prefrontal cortex (vmPFC) and the dorsal raphe nucleus. However, it remains unclear to what extent these findings translate to humans. During functional magnetic resonance imaging, we subjected participants to controllable and uncontrollable aversive but non-painful electric stimuli, as well as to a control condition without aversive stimulation. In each trial, a symbol signalled whether participants coul…
Individual baseline behavioral traits predict the resilience phenotype after chronic social defeat
2021
Abstract Chronic social defeat (CSD) has been widely used as a psychosocial stress model in mice, with the magnitude of CSD-induced social avoidance as the major behavioral hallmark of the resilient and susceptible groups. Despite significant progress in the study of the neurobiology of resilient and susceptible mice, the nature and ethological relevance of CSD-induced social avoidance and social approach, particularly measured using a CD1 mouse, needs conceptual clarification. Based on the findings of a recent study revealing substantial individuality in genetically homogeneous inbred mice, we investigated whether certain baseline individual characteristics of male C57BL/6J mice predict th…
Ethanol intake in male mice exposed to social defeat: Environmental enrichment potentiates resilience
2021
Large preclinical evidence shows that exposure to social defeat (SD) increases vulnerability to drug abuse, increasing the consumption of ethanol. However, not all subjects are equally affected by the changes induced by stress. Previous reports have evidenced that the resilient phenotype to depressive-like behaviors after SD is associated with the resistant phenotype to cocaine-increased rewarding effects and the smaller neuroinflammatory response. The aim of the present study was to further clarify whether the resilient profile to depressive-like behavior also predicts a protection against the increase in ethanol intake induced by SD. The neuroinflammatory profile was studied after the end…
