Treballs Finals de Grau de Química, Facultat de Química, Universitat de Barcelona, Any: 2019, Tutora: Saskia Speed CastroFive compounds have been synthesized in this work: [Co4(μ3-py2C(OH)O)4(4-Br-3-CF3-PhNCN)2 (PhCOO)2] (1), [Co4(μ2-py2C(OH)O)2(μ3-py2C(OCH3)O)2(μ2-4-Cl-PhNCN)2(4-Cl-PhNCN)2] (2), [Co(py2C(OH)O)(py2C(OCH2CH3)O)][NO3]·3H2O (3), [Zn2Tb(μ2-py2C(OCH2CH3)O)3(μ3-py2C(OCH2CH3)O) (NO3) (H2O)][Tb(NO3)5] (4) and [Dy5Co4(py2C(OH)O)4(μ3-py2CO2)4(μ4-py2CO2)2(O)2(H2O)6(NO3)2][NO3]5 (5). The metal ions of the five compounds are connected through oxo-bridges from the Di(2-pyridil) ketone derivatives formed after solvolysis and a posterior deprotonation. In addition the Co(II) atoms of compound 2 are connected by two R-phenylcyanamides in the end-on coordination mode. The magnetic susceptibility measurements were performed for compounds 1, 2, 4 and 5. Compound 1 and 2 exhibit a ferromagnetic coupling between the Co(II) metal ions. Compound 4 shows paramagnetic behaviour and 5 exhibit weak antiferromagnetic coupling between the Dy(II) ions. Compounds 1, 2 and 5 show SMM (Single Molecular Magnet) behaviour. The relaxation time of magnetization hasn’t been calculated

Saskia Sassen is the Robert S. Lynd Professor of Sociology at Columbia University and a Member of its Committee on Global Thought, which she chaired until 2015. She is a student of cities, immigration, and states in the world economy, with inequality, gendering, and digitization as three key variables running through her work. Born in the Netherlands, she grew up in Argentina and Italy, studied in France, was raised in five languages, and began her professional life in the United States. She is the author of eight books and the editor or co-editor of three books. Together, her authored books are translated into over twenty languages. She has received many awards and honors, among them multiple doctor honoris causa, the 2013 Principe de Asturias Prize in the Social Sciences, election to the Royal Academy of the Sciences of the Netherlands, and was made a Chevalier de l'Ordre des Arts et Lettres by the French government
Chiral dinuclear Ln(iii) complexes derived from S- and R-2-(6-methoxy-2-naphthyl)propionate. Optical and magnetic properties
The reaction of LnCl3·6H2O with (S)-(+)-2-(6-methoxy-2-naphthyl)propionic acid (S-HL), best known as naproxen, and 1,10-phenanthroline (phen) in EtOH allows the isolation of dinuclear chiral compounds S-1-4 of the formula [Ln2(S-L)6(phen)2]·3DMF·H2O [Ln(iii) = Eu (1), Gd (2), Tb (3) and Dy (4)]. The use of the R-enantiomeric species of the HL ligand led to complexes R-1-4 with the formula [Ln2(R-L)6(phen)2]·3DMF·H2O. Compounds R- and S-1, 3 and 4 show strong sensitized metal-centred luminescence in the visible region. Moreover, Dy(iii) complexes R- and S-4 display field-induced single-molecule magnet (SMM) behaviour. For chiral and emissive compounds circularly polarized luminescence (CPL) measurements have also been performed
De Taal van Muziek
Muziek is een complex en abstract sensorisch domein dat nauw verweven is met emotionele en culturele aspecten van de mens. Onderzoek naar hoe mensen muziek beschrijven kan inzichten bieden in de interactie tussen taal en andere cognitieve domeinen. Dit onderzoek richt zich op de vraag in hoeverre experts en niet-experts verschillen in hun beschrijvingen van klassieke muziekfragmenten. Om deze vraag te beantwoorden, werd een experiment uitgevoerd waarin 54 participanten twaalf muziekfragmenten beluisterden en deze beschreven. De resultaten hiervan toonden geen verschillen tussen experts en niet-experts in de lengte van de beschrijvingen. Niet-experts vertoonden echter meer overeenstemming in gebruikte descriptoren dan experts, vermoedelijk door een beperkter muzikaal vocabulaire van de niet-experts. Wat betreft typen descriptoren, gebruikten experts vaker geluidspecifieke termen, terwijl niet-experts vaker emoties en situationele associaties benoemden. Deze verschillen worden verklaard door zowel de perceptuele als talige training van muziekexperts. Dit onderzoek draagt bij aan ons begrip van de rol van expertise in de perceptie en conceptualisatie van abstracte sensorische domeinen zoals muziek
The creative industries: An entrepreneurial bricolage perspective
Purpose – The idea of “creating something from nothing” resonates strongly with the creation process associated with artists. The Levi-Strauss and Baker and Nelson discussions also refer to entrepreneurial bricolage as something that entails a “make do with what is at hand”. The purpose of this paper is to investigate how artists utilise bricolage to create projects and develop their skills. Little is known of their perceptions of entrepreneurial behaviour and bricolage, and how they construct these bricolage networks. The tension between sharing, creating and to maintain a personal brand is negotiated by leveraging these bricolage relationships. Design/methodology/approach – In-depth interviews with artists that actively make a living from their involvement in the creative industries were conducted. This provided insight into their perceptions on networking and bricolage. Since networking is such an individual and interchangeable process the interviews allowed the author to unravel these complexities of the relationships. Findings – The findings produced two themes. The first, demonstrated the entrepreneurial behaviour of these artists and their unique contributions. The second theme involved the bricolage relationships formed to overcome resource constraints. The collaborative nature highlighted the co-creation relationships that are strategically formed to provide long-term opportunities and sustained working relationships. Research limitations/implications – This study contributes to literature on bricolage, management, creative industries and entrepreneurship in non-traditional settings. Practical implications – This study contributes to theory on bricolage and entrepreneurial behaviour in small enterprises and creative industries. Artists can benefit from the knowledge to build strategic networks to secure future work. Social implications – Educators can use this information to prepare aspiring artists to create more independent and/or interdependent entrepreneurial projects. Originality/value – This work encourages further cross-disciplinary research on the arts, entrepreneurship, networking and small business studies. © Emerald Group Publishing Limited
Dialogical Skirmishes
Tan was guest editor for 'And Now China?', a special print edition of the Ctrl+P journal, which critically responded to the celebratory rhetoric’s of ‘China Now’ and other celebratory markers of China's global ascent in 2008. As well as the introductory article 'Dialogical Skirmishes', Tan also interviewed Hans Ulrich Obrist
