From hieroglyphics to Isotype: a visual autobiography (Otto Neurath)

Otto Neurath (1882–1945) wrote From hieroglyphics to Isotype during the last two years of his life and this is the first publication of the text in full, carefully edited from the original manuscripts. He called it a 'visual autobiography', in which he documents the importance of visual material to him from his earliest years to his professional activity with the picture language of Isotype. Neurath draws clear links between the stimulus he received as a boy from illustrated books, toys and exhibitions to the considered work in visual education that occupied him for the last two decades of his life. This engaging and informal account gives a rich picture of Central European culture around the turn of the twentieth century, seen through the eyes of Neurath's insatiable intelligence, as well as a detailed exposition of the technique of Isotype, a milestone of modern graphic design. This edition includes the numerous illustrations intended by Neurath to accompany his text, and is completed by an extensive appendix showing examples from the rich variety of graphic material that he collected.

Internationalized regimes: a second dimension of regime hybridity

Traditional approaches have conceptualized political regimes almost exclusively with reference to domestic-level political factors. However, many current and historical political regimes have entailed a major role for international actors, and in some cases the external influence has been so great that regimes have become internationalized. This article explores the concept of internationalized regimes and argues that they should be seen as a distinct form of hybrid regime type that demonstrates a distinct dimension of hybridity. Until now, regime hybridity has been conceived of along a single dimension of domestic politics: the level of competitiveness. Yet, some regimes are characterised by a different type of hybridity, in which domestic and international authority are found together within a single political system. The article explores the dynamics of internationalized regimes within three settings, those of international occupation, international administration and informal empire.

Can company-fund manager meetings convey informational benefits? Exploring the rationalisation of equity investment decision making by UK fund managers

Conventional economic theory, applied to information released by listed companies, equates ‘useful’ with ‘price-sensitive’. Stock exchange rules accordingly prohibit the selec- tive, private communication of price-sensitive information. Yet, even in the absence of such communication, UK equity fund managers routinely meet privately with the senior execu- tives of the companies in which they invest. Moreover, they consider these brief, formal and formulaic meetings to be their most important sources of investment information. In this paper we ask how that can be. Drawing on interview and observation data with fund managers and CFOs, we find evidence for three, non-mutually exclusive explanations: that the characterisation of information in conventional economic theory is too restricted, that fund managers fail to act with the rationality that conventional economic theory assumes, and/or that the primary value of the meetings for fund managers is not related to their investment decision making but to the claims of superior knowledge made to clients in marketing their active fund management expertise. Our findings suggest a disconnect between economic theory and economic policy based on that theory, as well as a corre- sponding limitation in research studies that test information-usefulness by assuming it to be synonymous with price-sensitivity. We draw implications for further research into the role of tacit knowledge in equity investment decision-making, and also into the effects of the principal–agent relationship between fund managers and their clients.

Numerical study of a M-cycle cross-flow heat exchanger for indirect evaporative cooling

In this paper, numerical analyses of the thermal performance of an indirect evaporative air cooler incorporating a M-cycle cross-flow heat exchanger has been carried out. The numerical model was established from solving the coupled governing equations for heat and mass transfer between the product and working air, using the finite-element method. The model was developed using the EES (Engineering Equation Solver) environment and validated by published experimental data. Correlation between the cooling (wet-bulb) effectiveness, system COP and a number of air flow/exchanger parameters was developed. It is found that lower channel air velocity, lower inlet air relative humidity, and higher working-to-product air ratio yielded higher cooling effectiveness. The recommended average air velocities in dry and wet channels should not be greater than 1.77 m/s and 0.7 m/s, respectively. The optimum flow ratio of working-to-product air for this cooler is 50%. The channel geometric sizes, i.e. channel length and height, also impose significant impact to system performance. Longer channel length and smaller channel height contribute to increase of the system cooling effectiveness but lead to reduced system COP. The recommend channel height is 4 mm and the dimensionless channel length, i.e., ratio of the channel length to height, should be in the range 100 to 300. Numerical study results indicated that this new type of M-cycle heat and mass exchanger can achieve 16.7% higher cooling effectiveness compared with the conventional cross-flow heat and mass exchanger for the indirect evaporative cooler. The model of this kind is new and not yet reported in literatures. The results of the study help with design and performance analyses of such a new type of indirect evaporative air cooler, and in further, help increasing market rating of the technology within building air conditioning sector, which is currently dominated by the conventional compression refrigeration technology.
