Hypes and the birth of new sustainable market categories – a socio-cultural perspective on the emergence of the meat substitute category in Finland
2022
Hypes can be a significant contributor in the mainstreaming of sustainable products. Former research on hypes has been supplier oriented, and thus little is known of their effect on new market formation. Our paper contributes to this research gap by examining the establishment of the ‘meat substitute’ category in Finland using press articles, retailer interviews and consumer panel data. We show how the emergence and legitimation of the meat substitute category depended heavily on the hype arising around a single product, called Pulled Oats (PO). This hype was anchored in its association with trendy and socio-culturally relevant values and practices. We further discover that the hype had pos…
Introduction to the special issue on just food system transition : Tackling inequalities for sustainability
2023
This special issue builds understanding of just transitions by looking at specific dynamics in food system transitions. The articles in the special issue apply a multi-dimensional understanding of justice, which stress that in addition to distributional matters, also recognition and procedural justice require attention in transitions. The current injustices in the food system emphasize the interrelatedness of these dimensions. The special issue includes eight articles that scrutinize food system transition in various contexts from Finland to Brazil and from farm-level decision-making to the UN food system summit. The papers demonstrate the focality of recognition justice for interpreting co…
Water-smart circular economy – Conceptualisation, transitional policy instruments and stakeholder perception
2022
Highlights • A concept for a water-smart Circular Economy (CE) is introduced. • Elements of a water-smart CE are presented. • Instruments to support the transition to a water-smart CE are analysed. • Drivers for and barriers to the transition to a water-smart CE are identified. The Circular Economy (CE) is a concept that has gained considerable global attention during the past decade amongst private and public sector actors, politicians and policymakers, citizens and media, and scientific communities. Water and water-related ecosystems, despite their vital role in practically all human activities, have been largely missing from conceptualisations and scientific definitions of the CE. Theref…

Transition metal chlorides complexes with tetrahydrofuran [MtCl(4)(THF)(2)] used as precursors of ethylene polymerization
2002
Otrzymano trzy kompleksy chlorków metali przejściowych z THF - [TiCl4(THF)2] (I), [ZrCl4(THF)2] (II), oraz [HfCWTHF),] (III) i zastosowano je jako prekursory katalizatorów tytanowo-magnezowych w niskociśnieniowej polimeryzacji (0,5 MPa, 323 K) etylenu przy użyciu AlEt3 (najkorzystniej), AlEt2Cl lub Al(z'-Bu)3 jako kokatalizatora (rys. 1, tabela 1). Zmierzono gęstość, gęstość nasypową, stopień krystaliczno-ści, ciężary cząsteczkowe i ich rozkład oraz temperaturę topnienia uzyskanego PE-HD (tabela 1). Aktywność katalizatorów wzrastała w szeregu (III) < (II) < (I), tzn. ze wzrostem elektroujemności pierwiastka metalu i ze spadkiem wartości ładunku cząstkowego na atomie metalu grupy przejściowe…
Dal liceo all’università: una ricerca-intervento per la costruzione del progetto di vita professionale degli studenti
2019
Si è conclusa nel mese di maggio del 2019 la prima parte di una ricerca-intervento ispirata alla teoria del pensiero narrativo, ai principi dell’educational counseling e della didattica orientativa. Durante l’anno scolastico 2018-2019, 93 studenti (50 femmine e 43 maschi) del quarto anno di cinque licei di Palermo hanno partecipato a un’iniziativa sperimentale in cui scuola e università hanno collaborato con un duplice scopo: ridurre negli studenti il gap rilevato tra le conoscenze in uscita dal liceo e quelle richieste all’inizio dei corsi universitari e potenziare in loro la capacità di formulare il proprio progetto di vita professionale. È stata sperimentata l’azione congiunta di tre tip…
Optimized Deposition of Graphene Oxide Langmuir-Blodgett Thin Films
2014
Abstract Single sheet graphene (SG) is an innovative transparent material with high electrical and thermal conduction the use of which in transparent electrodes instead of traditional materials improves the performance of optoelectronic devices. In this study, graphene oxide (GO) has been obtained by a modified Hummer`s method followed by an advanced technique of water removal (lyophilisation). The Langmuir-Blodgett (LB) method was applied to transfer GO from suspension to substrate. To optimize the deposition process, as suspending and spreading solvents the benzene and benzene/methanol mixtures were chosen instead of previously studied water suspensions. The number of GO layers in suspens…
Philosophy and language in young Nietzsche
2015
Resumo:O objetivo deste estudo é a exposição da filosofia da linguagem que Nietzsche apresenta em suas primeiras obras, sobretudo em seu decisivo escrito póstumo de 1873. São considerados três aspectos da trajetória de Nietzsche. Seu interesse pela linguagem poética e musical, desde a juventude; sua formação em filologia clássica; suas investigações filosóficas sobre o tema. Pretendemos mostrar como, nesse período, se parte de uma concepção metafísica para uma visão mais linguística. Nietzsche parte do fundamento metafísico para uma versão da linguagem como relação de signos e símbolos. Abstract:The purpose of this study is the explanation of the philosophy of language that Nietzsche presen…
Meanderings around the image of the hole. The Transition in the Scripts of the Body of
2018
El presente artículo se propone indagar acerca de la escritura del cuerpo femenino en la obra de la escritora Marta Sanz, a propósito de la relectura de la Transición española que contienen buena parte de sus novelas. Para ello, partiremos del análisis de la metáfora del agujero en varios de los textos de la autora. Este trabajo busca llamar la atención sobre la crítica a la evolución de las formas de violencia y de control ejercidas sobre el cuerpo femenino que contiene la obra de Marta Sanz, a partir de los textos Los mejores tiempos (2001), La lección de anatomía (2008), Daniela Astor y la caja negra (2013) y Éramos mujeres jóvenes. Una educación sentimental de la Transición española (20…
Representaciones de la transición española en la novela actual: una indagación en la configuración de la cultura democrática
2013
La noción de la transición como “matriz” de nuestro tiempo presente, como mito fundador de la España contemporánea es, hoy, uno de los puntos fundamentales de los debates culturales más recientes de nuestro país. Si consideramos el proceso de cambio político de la transición a la democracia como el punto de partida del proyecto democrático español aún vigente, el surgimiento de una serie de novelas centradas en el mismo resulta tan sintomático como oportuno. Por ello, en este artículo tratamos de interrogar las condiciones en las que ha aparecido esta serie de novelas, sus presupuestos comunes y los distintos núcleos de discusión a los que apuntan. Desde el análisis de la producción de una …
