Book Review: "The Interface: IBM and the Transformation of Corporate Design, 1945-1975", John Harwood, Minneapolis: University of Minnesota Press, 2011

Within the history of twentieth-century design, there are a number of well-known objects and stories that are invoked time and time again to capture a pivotal moment or summarize a much broader historical transition. For example, Marcel Breuer’s Model B3 chair is frequently used as a stand-in for the radical investigations of form and new industrial materials occurring at the Bauhaus in the mid-1920s. Similarly, Raymond Loewy’s streamlined pencil sharpener has become historical shorthand for the emergence of modern industrial design in the 1930s. And any discussion of the development of American postwar “organic design” seems incomplete without reference to Charles and Ray Eames’s molded plywood leg splint of 1942. Such objects and narratives are dear to historians of modern design. They are tangible, photogenic subjects that slot nicely into exhibitions, historical surveys, and coffee-table best sellers...

The enhanced Russell-based directional distance measure with undesirable outputs: Numerical example considering CO2 emissions

Following the spirit of the enhanced Russell graph measure, this paper proposes an enhanced Russell-based directional distance measure (ERBDDM) model for dealing with desirable and undesirable outputs in data envelopment analysis (DEA) and allowing some inputs and outputs to be zero. The proposed method is analogous to the output oriented slacks-based measure (OSBM) and directional output distance function approach because it allows the expansion of desirable outputs and the contraction of undesirable outputs. The ERBDDM is superior to the OSBM model and traditional approach since it is not only able to identify all the inefficiency slacks just as the latter, but also avoids the misperception and misspecification of the former, which fails to identify null-jointness production of goods and bads. The paper also imposes a strong complementary slackness condition on the ERBDDM model to deal with the occurrence of multiple projections. Furthermore, we use the Penn Table data to help us explore our new approach in the context of environmental policy evaluations and guidance for performance improvements in 111 countries.

The potential benefits of divergent thinking and metacognitive skills in STEAM learning: A discussion paper

In the wake of an almost decade long economic downturn and increasing competition from developing economies, a new agenda in the Australian Government for science, technology, engineering, and mathematics (STEM) education and research has emerged as a national priority. However, to art and design educators, the pervasiveness and apparent exclusivity of STEM can be viewed as another instance of art and design education being relegated to the margins of curriculum (Greene, 1995). In the spirit of interdisciplinarity, there have been some recent calls to expand STEM education to include the arts and design, transforming STEM into STEAM in education (Maeda, 2013). As with STEM, STEAM education emphasises the connections between previously disparate disciplines, meaning that education has been conceptualised in different ways, such as focusing on the creative design thinking process that is fundamental to engineering and art (Bequette & Bequette, 2012). In this article, we discuss divergent creative design thinking process and metacognitive skills, how, and why they may enhance learning in STEM and STEAM.

Lippu, uhri, kansakunta : Ryhmäkokemukset ja -rajat Suomessa 1917 1945

This dissertation deals with the notions of sacrifice and violence in connection with the Fin¬nish flag struggles between 1917 and 1945. The study begins with the basic idea that sacrificial thinking is a key element in nationalism and the social cohesion of large groups. The method used in the study combines anthropological notions of totemism with psychoanalytical object relation theory. The aim is to explore the social and psychological elements of the Finnish national flag and the workers flags during the times of crisis and nation building. The phenomena and concepts addressed include self-sacrifice, scapegoating, remembrance of war, inclusion, and exclusion. The research is located at the intersection of nationalism studies and the cultural history of war. The analysis is based primarily on the press debates, public speeches and archival sources of the civic organizations that promoted the Finnish flag. The study is empirically divided into three sections: 1) the years of the Revolution and the Civil War (1917 1918), 2) the interwar period (1919 1938), and 3) the Second World War (1939 1945). The research demonstrates that the modern national flags and workers flags in Finland maintain certain characteristics of primitive totems. When referred to as a totem the flag means an emotionally charged symbol, a reservoir of the collective ideals of a large group. Thus the flag issue offers a path to explore the perceptions and memory of sacrifice and violence in the making of the First Republic . Any given large group, for example a nation, must conceptually pursue a consensus on its past sacrifices. Without productive interpretation sacrifice represents only meaningless violence. By looking at the passions associated with the flag the study also illuminates various group identities, boundaries and crossings of borders within the Finnish society at the same time. The study shows further that the divisive violence of the Civil War was first overcome in the late 1930s when the social democrats adopted a new perception of the Red victims of 1918 they were seen as part of the birth pains of the nation, and not only the martyrs of class struggle. At the same time the radical Right became marginalized. The study also illuminates how this development made the Spirit of the Winter War possible, a genuine albeit brief experience of horizontal brother and sisterhood, and how this spirit was reflected in the popular adoption of the Finnish flag. The experience was not based only on the external and unifying threat posed by the Soviet Union: it was grounded in a sense of unifying sacrifice which reflected a novel way of understanding the nation and its past sacrifices. Paradoxically, the newly forged consensus over the necessity and the rewards of the common sacrifices of the Winter War (1939 1940) made new sacrifices possible during the Continuation War (1941 1944). In spite of political discord and war weariness, the concept of a unified nation under the national flag survived even the absurdity of the stationary war phase. It can be said that the conflict between the idea of a national community and parliamentary party politics dissolved as a result of the collective experience of the Second World War.

Differential fluorescence of the chromocenters and nucleolar equivalents of the yeast nucleus in acridine orange

The nucleus with its limiting membrane and organelles was visible in the majority of the yeast cells stained vitally with the fluorochrome, acridine orange, at a dilution of 1 in 40,000. The intra-nuclear structures could be distinguished by their differential fluorescence. The chromocenters were green while the nucleolar equivalents were orange. The vacuole showed no fluorescence.

Global capitalism meets national spirit: Discourses in media texts on a cross-border acquisition

In this article, the authors explore media coverage of a recent acquisition across national borders. Their starting point is that the media represent a key arena of “discursive strategizing” for actors such as corporate managers. They illustrate and specify how global capitalism, as discourse relying on economic and financial rationale and exemplified here by the acquiring firm’s attempts to expand, meets national spirit, exemplified here by the complexity in selling the acquisition target to foreigners. The main contribution of this study lies in identifying how key actors draw on and mobilize rationalistic and nationalistic discourses in public discussion. The analysis illustrates that the same actors can draw on different—even contradictory—discourses at different points in time. Furthermore, different actors—even with opposing objectives—may draw on the same discourse in legitimizing their positions and pursuing specific ends.

Mode shapes during asynchronous motion and non-proportionality indices

When synchronous motion does not exist, it is not possible to draw the classical mode shapes. In this paper, a representative shape of motion during free vibration of a non-classically damped system is sought. It is noted that this shape provides an optimal representation of free motion. Interpretations of the optimality thus introduced are presented. Their connection with non-proportionality of damping and of gyroscopy is brought out. In the spirit of the optimality presented in this paper, two indices of non-proportionality are defined. Properties of these indices are discussed. Comparison with other indices of non-proportionality available in the literature is presented. Illustrative examples are given. (C) 1999 Academic Press.

Effect of Zr4+-ion substitution in CeO2 on H2O2-assisted degradation of orange G

A series of Pd ion-substituted CeO2-ZrO2 solid solutions were synthesized using the solution combustion technique. H2O2-assisted degradation of orange G was carried out in the presence of the catalysts. The activity of the catalysts was found to increase with the introduction of the second component in the solid solution, as signified by an increase in the rate constants and lowering of activation energy. The study showed the involvement of lattice oxygen and the importance of reducibility of the compound for the reaction. (C) 2011 Elsevier B.V. All rights reserved.

278. Studies on ass's milk: Composition

The total solids of samples of ass's milk ranged from 7·80 to 9·10, the solids-not-fat from 7·14 to 8·50, and the fat from 0·54 to 0·71%. The nitrogen distribution in ass's milk is: casein 39·5, albumin 35·0, globulin 2·7 and non-protein nitrogen 22·8% of the total nitrogen. Ass's milk contains: casein 0·70, albumin 0·62 and globulin 0·07%. The total protein content is 1·39%. Ass's milk is therefore characterized by a low casein, a low globulin and a high albumin content. The non-protein nitrogen consists of amino nitrogen 8·1, urea nitrogen 24·3 and uric acid 0·7 mg./100 ml. of milk. The urea content is twice that present in cow's milk. The mean chloride and lactose contents of the milk samples are 0·037 and 6·1% respectively. The average calcium and phosphorus content of ass's milk are 0·081 and 0·059% respectively. Half the calcium is ionic, and half is in colloidal form. The phosphorus distribution is: total acid soluble 84·0, acid soluble organic 38·5, easily hydrolysable ester 27·4, inorganic 46·0, and colloidal inorganic 23·0 % of the total phosphorus. The ratio of CaO: P2O5 is 1:1. 46 % of the total phosphorus is in ester form; this is high when compared with only 12 % in cow's milk; most of the phosphoric ester forms soluble barium salts, which is a distinguishing feature of ass's milk. The total sulphur content is 15·8 mg./100 ml. The fat has a penetrating odour and is coloured orange-yellow. It has an iodine value of about 86, which is much higher than that for human milk fat. The Reichert (9·5) and Kirschner values (5·7) are low. In general, the composition of ass's milk resembles that of human rather than of cow's milk.

Biological sulfate reduction of a sulfate-rich industrial waste liquor using sulfate reducing bacteria

An industrial waste liquor having high sulfate concentrations was subjected to biological treatment using the sulfate-reducing bacteria (SRB) Desulfovibrio desulfuricans. Toxicity levels of different sulfate, cobalt and nickel concentrations toward growth of the SRB with respect to biological sulfate reduction kinetics was initially established. Optimum sulfate concentration to promote SRB growth amounted to 0.8 - 1 g/L. The strain of D. desulfuricans used in this study initially tolerated up to 4 -5 g/L of sulfate or 50 mg/L of cobalt and nickel, while its tolerance could be further enhanced through adaptation by serial subculturing in the presence of increasing concentrations of sulfate, cobalt and nickel. From the waste liquor, more than 70% of sulfate and 95% of cobalt and nickel could be precipitated as sulfides, using a preadapted strain of D. desulfuricans. Probable mechanisms involving biological sulfide precipitation and metal adsorption onto precipitates and bacterial cells are discussed.

Design of a manual press for the production of compacted stabilized soil blocks

In this paper, we discuss the design of a manually operated soil compaction machine that is being used to manufacture stabilized soil blocks (SSB). A case study of manufacturing more than three million blocks in a housing project using manually operated machines is illustrated. The paper is focussed on the design, development, and evaluation of a manually operated soil compaction machine for the production of SSB. It also details the machine design philosophy, compaction characteristics of soils, employment generation potential of small-scale stabilized soil block productions systems, and embodied energy. Static compaction of partially saturated soils was performed to generate force-displacement curves in a confined compaction process were generated. Based on the soil compaction data engineering design aspects of a toggle press are illustrated. The results of time and motion study on block production operations using manual machines are discussed. Critical path network diagrams were used for small-scale SSB production systems. Such production systems generate employment at a very low capital cost.
