Phenomenal Change And Adolescents’ Psychological Disinterest In Commitments: A Concern For The Family Traditions
2015
The phenomenal changes such as biological, physical, social, technological and global changes, vitally affect the psychological uncertainty and pre-occupation in the minds of the adolescents. (Leckman et al., 2002, p.324). A lethargic attitude, avoidance of responsibility creeps into their system during this period, leading them to more socialising and less psychological commitments. (Jakubowski & Dembo, 2004). Researches show that Adolescents who were isolating themselves from family events and desiring only social events outside family tend to develop ‘low levels of commitment and self-regulatory resources, and they perceived their parents as being low in trust, openness, and supervision.…

EVOLUTION OF LABOR MARKET AND OCCUPATIONAL MEDICINE IN A CHANGING WORLD: ANALYSIS OF THE ITALIAN DATA 2000-2019 AND POSSIBLE CONSEQUENCES OF THE ECON…
2022
Introduction: The first two decades of the third millennium have been characterized by deep economic changes in various countries around the world with an inevitable impact on the job market. The aim of this study is to analyze the data of the last twenty years relating to employment in Italy, compared with European ones, to understand how the 2008 economic crisis affected employment in the following years and how the recent crisis, related to the COVID 19- pandemic emergency, may contribute further. Methods: The study analysed data related to the labor market in Italy and in the European Countries. The 2000-2019 period was analytically evaluated by comparing employment and unemployment rat…
The organic carbon derived from sewage sludge as a key parameter determining the fate of trace metals.
2007
8 pages; International audience; In a sandy agricultural soil of south-west of France, continuously cultivated with maize and amended with sewage-sludge over 20 years, the behavior of three trace metals (Cu, Pb, and Zn) was studied during the sludge applications (1974-1993) and after its cessation (1993-1998). Using the delta13C analysis, the dynamics of different sources of organic matter were followed in order to elucidate the influence of the sludge-derived organic matter on the fate of trace metals in the soil and its particle size fractions. This study revealed that sludge-derived organic matter contributed to the formation of macroaggregates through the binding of preexisting microagg…
Shoreline Evolution and Environmental Changes at the NW Area of the Gulf of Gela (Sicily, Italy)
2021
Coastal areas are among the most biologically productive, dynamic and valued ecosystems on Earth. They are subject to changes that greatly vary in scale, time and duration and to additional pressures resulting from anthropogenic activities. The aim of this work was to investigate the shoreline evolution and the main environmental changes of the coastal stretch between the towns of Licata and Gela (in the Gulf of Gela, Sicily, Italy). The methodology used in this work included the analysis of: (i) shoreline changes over the long- and medium-term periods (1955–2019 and 1989–2019, respectively), (ii) dune system fragmentation and (iii) the impact of coastal structures (harbours and breakwaters…
Ādas izmaiņas pacientiem ar sistēmisku sarkano vilkēdi (SSV)
2018
Pētījuma nosaukums: Ādas izmaiņas pacientiem ar sistēmisku sarkano vilkēdi (SSV) Vispārēja informācija: Sistēmiska sarkanā vilkēde ir multifaktoriāla slimība ar plašu klīnisko izpausmju spektru. Ādas slimības ir svarīgs sarkanās vilkēdes klīniskais aspekts, jo āda ir otrs visbiežāk skartais orgāns pēc muskuļu un skeleta sistēmas. Saistībā ar to ādas izmaiņas var būt izšķirošas, lai agrīni atklātu sistēmisko slimību un to pienācīgi ārstētu.Mērķi. Galvenais pētījuma mērķi ir atrast, vai pastāv korelācija starp ādas izmaiņām, kuras var parādīties pacientiem ar sistēmisku sarkano vilkēdi un slimības aktivitāti. Un noteikt ādas bojājumus, kuriem ir saistība ar slimības aktivitāti. Materiāli un m…
BIOCHARS IN SOILS: TOWARDS THE REQUIRED LEVEL OF SCIENTIFIC UNDERSTANDING
2017
The special issue on Biochar as an Option for Sustainable Resource Management Key priorities in biochar research for future guidance of sustainable policy development have been identified by expert assessment within the COST Action TD1107. The current level of scientific understanding (LOSU) regarding the consequences of biochar application to soil were explored. Five broad thematic areas of biochar research were addressed: soil biodiversity and ecotoxicology, soil organic matter and greenhouse gas (GHG) emissions, soil physical properties, nutrient cycles and crop production, and soil remediation. The highest future research priorities regarding biochar’s effects in soils were: functional …
Contamination of soil by copper affects the dynamics, diversity, and activity of soil bacterial communities involved in wheat decomposition and carbo…
2009
ABSTRACT A soil microcosm experiment was conducted to evaluate the influence of copper contamination on the dynamics and diversity of bacterial communities actively involved in wheat residue decomposition. In the presence of copper, a higher level of CO 2 release was observed, which did not arise from greater wheat decomposition but from a higher level of stimulation of soil organic matter mineralization (known as the priming effect). Such functional modifications may be related to significant modifications in the diversity of active bacterial populations characterized using the DNA stable-isotope probing approach.
Improvement of the photo-stability of polystyrene-block-polybutadiene-block-polystyrene through carbon nanotubes
2015
Abstract The photo-stability of Polystyrene-Polybutadiene-Polystyrene (SBS) based nanocomposites containing bare multi-walled carbon nanotubes (CNTs) and carbon nanotubes bearing carboxylic functional groups (CNTs-COOH) in comparison to that of pristine SBS has been studied. The photo-oxidation of pristine SBS occurs through crosslinking reactions and oxidized species formation and both these processes begin at early stage of exposure. The formation of crosslinking, formerly in polybutadiene phase, assessed by spectroscopical (FTIR), mechanical, dynamic mechanical and rheological analysis, leads to occurrence of internal mechanical stresses in the solid state and the SBS samples become prem…
Soviet-American Art Exchanges during the Thaw: from Bold Openings to Hasty Retreats
2013
[Introduction] East-West artistic connections during the Cold War were a complex range of phenomena including the circulation of works of art, travelling by art professionals, the exchange of practices and the adoption of art currents from the other side of the Iron Curtain. The Cold War has also been said to have influenced the arts and artistic processes in a number of ways. Yet, art has always shunned political borders, wavering between the guidance of individual and governmental patrons, and borderless expression. This chapter discusses an attempt at an extensive exchange of exhibitions between the Soviet Union and the United States around the late 1950s that involved New York’s Museum …
