Erika Love (1925–2020)

Erika Love, MLA president and early advocate for research in libraries, died October 8, 2020. Erika held many leadership positions in the profession and received several MLA awards recognizing her contributions. She has been called “the midwife” of MLA''s early research initiatives [1].

Erika Love, Medical Library Association (MLA) president and early advocate for research in libraries, died October 8, 2020, at the age of 95. Born in Germany, Erika grew up in an educated and culturally rich environment. Her family did not support the National Socialism regime and suffered political persecution and economic hardship. After World War II, she matriculated at the University of Heidelberg. She worked as a library assistant at Amerika Haus in Darmstadt, a postwar organization fostering cultural interchange. In 1948, Erika married Victor Lamar Love; they moved to Indiana, his home state [2].     

Scientific Ideas Held by Intending Primary Teachers in Britain and Spain

This paper offers a comparative analysis of some science concepts held by intending primary teachers in Britain and Spain. Drawing on personal construct theory, a questionnaire was devised to elicit concepts of volume, mass and conservation of mass, and their application to physical and chemical transformations. The results from the two countries show the difficulties students have in applying the conservation of mass to the apparently simple cases offered here. The replies are analysed in terms of differences in national curricula and in the range of science previously studied. The implications for teacher education are elaborated.     

Specificities of the artistic cultural labor market in Brazilian metropolitan regions between 2002 and 2010

This paper analyzes the singularity of artistic cultural sector workers in the Brazilian metropolitan labor market, considering the job satisfaction of artists that Throsby proposes in his work preference model of artist behavior (1994). We also examine the effect of public expenditures on the income of workers in the cultural sector. Using 2002 to 2010 data from the Monthly Employment Survey (PME) and administrative records from Finance of Brazil (FINBRA), we estimate a probit model and a wage equation. In our model, we estimate wages as a function of: (1) sociodemographic characteristics of workers, (2) a variable for informal jobs, (3) the number of working hours, (4) a variable for the worker having another job, (5) per capita expenditures on culture interacted with a dummy for artistic cultural workers, (6) interactive binary variables involving place of residence and artistic cultural workers and (7) the predicted probability obtained by the probit model. This probability is estimated based on the likelihood of working in a creative activity, considering both workers from the cultural sector and other workers, controlled by: (1) sociodemographic characteristics of workers, (2) characteristics of their jobs, (3) dummies for the metropolitan regions and (4) willingness of creative workers to work additional hours interacted with the number of hours worked. Our results show that workers in the cultural sector are likely to work longer hours when compared to workers in other sectors. For our wage equation, the results suggest that women earn relatively less than men and blacks earn less than whites. Furthermore, earnings increase with age and the level of education. Formal workers obtain higher earnings when compared to informal ones. Finally, an increase in the per capita public expenditure on the cultural sector raises the income of workers in artistic cultural occupations.     

Ageing of brazilwood dye in wool – a chromatographic and spectrometric study

Brazilwood was used in this work to dye wool mordanted with different amounts of copper(II) sulfate, alum and iron(II) sulfate. Two different dyeing methods were used: premordanting (MD) and simultaneous mordanting (M+D) procedures. In order to evaluate the influence of the mordant ion in the brazilein chromophore photodegradation, samples were subjected to artificial light ageing. Color measurements were made and, for the first time, LC-DAD-ESI-MS was used for chromophore analysis of the dyed fibers before and after light exposure. Mordant ion quantification was done after fiber acid digestion, by inductively coupled plasma-optical emission spectroscopy (ICP-OES) and flame atomic absorption spectroscopy (FAAS). Mordant metal ion, mordant bath concentration and dyeing procedure were found to have strong influence in the wool fiber hues. Color variation was more pronounced in the alum dyed samples. Overall, mordant quantification showed that the amount of metal ions found in the fibers is very small when compared to the original concentrations of the dyeing bath, being Cu the ion with greater affinity for the wool fibers. MD dyeing procedure yielded fibers with larger amounts of mordant metal ions and higher chromophore peak areas. Higher amounts of brazilein were extracted from wool mordanted with copper(II) sulfate. Finally, chromatographic analysis of the brazilwood dyed samples before and after light exposure resulted in the detection of Type C compound as an outcome of the photodegradation process.     

Riding the Wave to Reach the Masses: Natural Events in Early Twentieth Century Portuguese Daily Press

This paper brings together science communicated in newspapers in Portugal by looking at how news on natural events were communicated in two different newspapers—the capital newspaper Diário de Notícias (Daily News) and the Diário dos A?ores (Azores Daily). In particular, we look at how the 1900 solar eclipse, a hot topic throughout Europe, was reported by the capital newspaper, and how news on seismology were conveyed in the period 1907–1910 in the newspaper published in Azores, an archipelago with a significant seismic and volcanic activity. We argue that the importance conceded to these scientific news was related to their overwhelming features, that their dissimilar presentation stemmed from their local relevance allied to their different nature, predictable in the case of eclipses, and unpredictable in the case of earthquakes, and that behind these two instances of science journalism laid an attempt by the scientific and political communities to gain the support of the general public to such an extent that these two specific instances of science journalism transcended their usual features to become successful forms of expository science.     

The civic‐minded instructional designers framework: An alternative approach to contemporary instructional designers' education in higher education

This paper argues that an emphasis on training‐for‐the‐job approaches has distracted designers from thinking about the meaning of their profession and the grand purpose of practising instructional design. Drawing from literature in the fields of sociology and educational technology, this paper synthesises discourses on civic professionalism in instructional design and technology, and proposes a conceptual framework that highlights the roles and qualities of a civic‐minded instructional designer. It is claimed that a critical discussion on civic professionalism in the field of educational technology can offer an alternative perspective on educating instructional designers, and have practical implications on instructional design and technology curricula in higher education.
