Application of circular economy principles and the technical, social and economical prospects in Estonian construction sector

Ehitusinseneriõppe lõputöö Maaehituse õppekavalJätkusuutlikku arengut ja keskkonnahoidu puudutavate teemade olulisuse tõus on viimastel aastatel suurendanud poliitilist survet laiemate muudatuste tegemiseks majandusmudelites ja seadusandluses. Euroopa Liidu liikmesriigina on ka Eesti võtnud kohustuse ringimajanduse majandusmudelile üleminekuks. Tulevikustrateegiates seatud eesmärgid on jõudmas erinevate valdkondade igapäevaellu ning mõjutavad erivaldkondade tulevikuplaane ja -strateegiaid. Ehitussektor toodab ligikaudu kolmandiku maailma prügist. Seega on ringmajanduses oluline roll just ehitussektoril, kus tuleb lahendada mitmeid ressursikasutust puudutavateid küsimusi nagu jäätmetekke piiramine, taaskasutuse osakaalu suurendamine ja ka kahjulike keskkonnamõjude vähendamine. Käesoleva töö eesmärgiks oli hinnata Eesti ehitussektori valmisolekut ringmajandusemudeliga kaasnevate eesmärkide saavutamiseks. Töö põhieesmärk oli ettevõttesisestele protseduuridele, ringmajanduslikele ilmingutele ning teemaga haakuvatele sotsiaalsetele ja tehnilistele elementidele analüüs. Uuringu käigus viidi läbi intervjuud ehitustöödega kokku puutuvate isikutega, töö mille käigus kaardistati kriitilisemad kitsaskohad. Saadud teabe põhjal viidi läbi analüüs, mille põhjal anti soovitused edasiste tegevuste planeerimiseks. Töö käigus selgus, et kuigi inimesed peavad jätkusuutlikkust ja keskkonnahoidu oluliseks, tuleb ringmajanduse mõiste tutvustamiseks teha täiendavat teavitustööd. Tulemustest selgus, et kuigi Eesti ehitusvaldkonnas esineb ringmajanduslikke ilminguid, on valdavalt tegu siiski isetekkeliste protsessidega. Mõningal määral esineb juba teadlikku ringmajanduslikku käitumist, kuid hetkel puudub seadusandlik raamistik antud tegevuste ja ressursside planeerimiseks. Lisaks selgus uuringust, et ehitusobjektide materjalikasutuse tõhusust pärsivad ebamäärased seadused ja nõuded, vähene kontroll ja mõõdetavus, ringmajandust toetava riikliku süsteemi puudumine, ettevõttesiseste ressursside ja motivatsiooni nappus ning majanduslikult veenvate argumentide puudumine.The growing importance of sustainable development and environmental issues has in recent years increased political pressure for broader changes in economic models and legislation. As a member of the European Union, Estonia is also taking steps to move towards circular economy model. Changes resulting from the trajectory of future strategies are entering the everyday life of various fields and have a significant impact on planning ahead. The construction sector, which produces about a third of the world's waste, faces a number of resource use issues, the most critical of which are limiting waste generation, increasing the share of recovery and reducing adverse environmental impacts. The aim of the thesis was to assess the readiness of the Estonian construction sector to adapt to the innovations accompanying the circular economy model. The thesis focused on the analysis of internal company procedures, circular economic phenomena and related social and technical elements. For this, interviews were conducted with people involved in construction work. The most critical issues were mapped during the work, which were analyzed for making recommendations in planning further activities in the construction sector. The work indicated that although people consider sustainability and environmental protection to be important, the introduction of the circular economy concept needs further introduction. The interviews indicated that although circular economic phenomena exists in the Estonian construction sector, these are mostly spontaneous processes. Targeted circular economic behavior already exists to some extent, but there is currently no legislative framework for planning activities and resources. Additionally, the study revealed that the materials efficiency on construction sites is hampered by vague laws and requirements, lack of control and measurability, lack of a state system to support circular economy, absence of internal resources and motivation, and shortage of economically convincing arguments

Exogenous spatial precuing reliably modulates object processing but not object substitution masking

Object substitution masking (OSM) is used in behavioral and imaging studies to investigate processes associated with the formation of a conscious percept. Reportedly, OSM occurs only when visual attention is diffusely spread over a search display or focused away from the target location. Indeed, the presumed role of spatial attention is central to theoretical accounts of OSM and of visual processing more generally (Di Lollo, Enns, & Rensink, Journal of Experimental Psychology: General 129:481–507, 2000). We report a series of five experiments in which valid spatial precuing is shown to enhance the ability of participants to accurately report a target but, in most cases, without affecting OSM. In only one experiment (Experiment 5) was a significant effect of precuing observed on masking. This is in contrast to the reliable effect shown across all five experiments in which precuing improved overall performance. The results are convergent with recent findings from Argyropoulos, Gellatly, and Pilling (Journal of Experimental Psychology: Human Perception and Performance 39:646–661, 2013), which show that OSM is independent of the number of distractor items in a display. Our results demonstrate that OSM can operate independently of focal attention. Previous claims of the strong interrelationship between OSM and spatial attention are likely to have arisen from ceiling or floor artifacts that restricted measurable performance
