Osallisuuden lisääminen : Habermasin kommunikatiivisen toiminnan teoriaa mukaillen
2017
Tämä filosofian alaan kuuluva tutkimus käsittelee osallisuutta ja sen lisäämistä peruskoulussa käyttäen menetelmänä Habermasin kehittämää kommunikatiivisen toiminnan teoriaa. Tutkimuksen tarkoituksena on tuoda esille osallisuus-käsitteen eri merkityssisältöjä ja esitellä menetelmä, jota soveltaen osallisuuden kokemista ja tunnetta osallisuudesta voidaan lisätä. Osallisuus, jota tässä opinnäytetyössä tutkitaan, nousi korostetusti esille vuoden 2014 Perusopetuksen opetussuunnitelman perusteissa mutta edellä mainituissa perusteissa ei tuotu tämän tutkimuksen tekijän mielestä esille, mitä osallisuus on tai miten sitä lisätään oppilaiden keskuudessa. Tässä tutkimuksessa tuodaan esille, että Habe…
Tuntemusten paikkansapitävyys tiellä ja maastossa juniori- ja miessuunnistajilla
2008
Suomalaisessa kestävyysvalmennuksessa sekä nuorten että vanhempien urheilijoidenosalta harjoittelu tapahtuu usein urheilijan omiin suorituksen aikaisiin tuntemuksiinperustuen. Kuitenkin on olemassa hyvin vähän tietoa, vastaako tuntemuksien mukaanharjoittelu kulloinkin tavoitteena olevia todellisia harjoitusvauhteja. Tämän tutkimuksentarkoitus on selvittää osaavatko mies- ja poikasuunnistajat juosta tuntemuksienperusteella tavoitteena olevalla sykealueella tiellä ja maastossa.Tutkimukseen osallistui 13 koehenkilöä, jotka kuuluivat miesten (n=6) ja poikien (n=7)ryhmiin. Iältään koehenkilöt jakautuivat yli ja alle 20-vuotiaisiin. Kaikki koehenkilötsuorittivat tutkimuksen alussa 2,8 km:n arvioj…
Enhancing Bioactive Antioxidants’ Extraction from “Horchata de Chufa” By-Products
2018
During the production of a traditional drink produced from the tubers of Cyperus esculentus L. also known as “horchata de chufa,” a high quantity of by-products are generated. These by-products are rich with valuable biological compounds, hence, there is a need to report their extraction conditions for further use in food production as raw materials. Therefore, the objective of this study was to evaluate and improve the conventional extraction process, applied for recovery of phenolic compounds, total flavonoids, and total antioxidant capacity from the by-products. Independent variables for extraction were: (i) Solvent type (mixtures of ethanol-water (v/v) at 0%, 25% and 50%)
Glyphosate-based herbicide has soil-mediated effects on potato glycoalkaloids and oxidative status of a potato pest
2020
Glyphosate is the most used herbicide worldwide, targeting physiological pathways in plants. Recent studies have shown that glyphosate can also cause toxic effects in animals. We investigated the glyphosate-based herbicide (GBH)-induced changes in potato (Solanum tuberosum) plant chemistry and the effects of a GBH on the survival rate and oxidative status of the Colorado potato beetle (Leptinotarsa decemlineata). The beetles were reared on potato plants grown in pots containing soil treated with a GBH (Roundup Gold, 450 g/l) or untreated soil (water control). The 2nd instar larvae were introduced to the potato plants and then collected in 2 phases: as 4th instar larvae and as adults. The ma…
Unequal poverty and equal industrialisation: Finnish wealth, 1750–1900
2018
We present the first comprehensive, long-run estimates of Finnish wealth and its distribution from 1750 to 1900. Using wealth data from 17,279 probate inventories, we show that Finland was very unequal between 1750 and 1850; the top decile owned about 90% of total wealth. This means that Finland was more unequal than the much wealthier economies Britain, France and the US, which goes against the common assumption of richer economies being more unequal. Moreover, when industrialisation took off in Finland, inequality started a downward trajectory. High inequality 1750–1850 was bottom-driven, by a large share of the population owning nothing or close to nothing of value, while economic develo…
Effect of plant species on water balance in a pilot-scale horizontal subsurface flow constructed wetland planted with Arundo donax L. and Cyperus alt…
2015
Abstract In constructed wetland systems (CWs) for wastewater treatment, evapotranspiration (ET) is the most important water balance component in arid and semi-arid regions, where high performance levels are needed when treating contaminants and where it is also vital to preserve as much water as possible for reuse in irrigation. This study shows the results of a series of water balance measurements obtained between 2012 and 2013 from a pilot HSSF system in the West of Sicily (Italy). The system was made by two separate vegetated units: one with Arundo donax L. (giant reed) and the other with Cyperus alternifolius L. (umbrella sedge), and fed with urban wastewater following secondary treatme…
Fresh-cut products from cactus species
2005
Various species of Cactaceae family can serve a source of delicious and healthy fresh foodstuffs. Marketing cacti as ready-to-eat (fresh-cut) products may significantly expand their consumption, on condition that their quality, safety and longevity would answer the market demands. The present work was aimed at studying the storability of fresh-cut products prepared from several edible cactus species and looking for ways to improve their keeping quality. The experiments included fruit of cactus pear Opuntia ficus-indica (L.) Miller, cactus apple (koubo) Cereus peruvianus (L.) Miller, and dragon fruit (pitaya) Hylocereus undatus (Haw.) Britton and Rose, as well as cladodes (pads) of nopal (ve…
