Art as collaboration: 50 years of Edition Hansjörg Mayer
Extensive interview with artist, graphic designer and publisher Hansjörg Mayer by Eleanor Vonne Brown and Gustavo Grandal Montero, focusing particularly on his seminal work of the 1960s. Associated at an early stage with Max Bense’s Stuttgart Group, he developed his own “typoems” and other forms of experimental visual poetry, often employing complex conceptual methods (e.g. “typoactions”). His published output includes prints, portfolios, books and the broadsheet series ‘Futura’
Relationships between emotional intelligence and sales performance in Kuwait
This study investigates the relationship between emotional intelligence (EI) and Total Sales Performance (TSP), and whether EI contributes to predicting the performance of sales professionals in Kuwait. The sample was 218 sales professionals working for 24 different car dealerships. An ability model of EI was measured using the Assessing Emotions Scale (AES) developed by Schutte et al. (1998) and its Arabic version. The trait model of EI was assessed using the Effective Intelligence Scale (EIS). The findings showed a negative but weak correlation between TSP and the AES and all its subscales. No correlation was found between TSP and the EIS. A weak positive correlation existed between Objective Sales Performance and each of total EIS, Accuracy, and Patience subscales
Xeno Amino Acids: A look into biochemistry as we don't know it
Would another origin of life resemble Earth's biochemical use of amino acids?
Here we review current knowledge at three levels: 1) Could other classes of
chemical structure serve as building blocks for biopolymer structure and
catalysis? Amino acids now seem both readily available to, and a plausible
chemical attractor for, life as we don't know it. Amino acids thus remain
important and tractable targets for astrobiological research. 2) If amino acids
are used, would we expect the same L-alpha-structural subclass used by life?
Despite numerous ideas, it is not clear why life favors L-enantiomers. It seems
clearer, however, why life on Earth uses the shortest possible (alpha-) amino
acid backbone, and why each carries only one side chain. However, assertions
that other backbones are physicochemically impossible have relaxed into
arguments that they are disadvantageous. 3) Would we expect a similar set of
side chains to those within the genetic code? Not only do many plausible
alternatives exist and evidence exists for both evolutionary advantage and
physicochemical constraint for those encoded by life. Overall, as focus shifts
from amino acids as a chemical class to specific side chains used by post-LUCA
biology, the probable role of physicochemical constraint diminishes relative to
that of biological evolution. Exciting opportunities now present themselves for
laboratory work and computing to explore how changing the amino acid alphabet
alters the universe of protein folds. Near-term milestones include: a)
expanding evidence about amino acids as attractors within chemical evolution;
b) extending characterization of other backbones relative to biological
proteins; c) merging computing and laboratory explorations of structures and
functions unlocked by xeno peptides.Comment: Submitted to Life (ISSN 2075-1729), 26 pages (without references), 8
