The IAU, from New Worlds to Exoworlds: recollections of a mandate
Authors: Montmerle Thierry 
Published: April 2019

AbstractThis paper presents my own recollections of the difficult relations that existed between the IAU and a fraction of the public, especially in the USA, following the IAU decision to reclassify Pluto as a dwarf planet at the 2006 General Assembly in Prague, and which ultimately led the IAU to organize the NameExoWorlds international contest to give public names to selected exoplanets and their host stars. In spite of the success of the International Year of Astronomy in 2009, the Pluto controversy continued, and its consequences climaxed during my term (2012-2015), as NASA’s New Horizons probe approached Pluto for a flyby just before the 2015 General Assembly in Honolulu. It was during this period that the IAU launched the NameExoWorlds contest, which also came to a conclusion in Honolulu after over half a million votes were cast from all over the world. While the inside story of how the contest was organized has appeared elsewhere, here I focus on the historical and sociological context that made Pluto such a sensitive issue, especially in the USA, explaining why this contest generated another controversy between the IAU and the New Horizons team. However, after the world-wide success of NameExoWorlds, the IAU and the New Horizons team eventually reached an agreement on finalizing the characterization and names of a number of newly discovered Pluto and Charon surface features (an on-going process), while a new edition of NameExoWorlds is in preparation for the IAU centennial in 2019.
IAU General Secretary 1997–2000
Authors: Andersen Johannes 
Published: April 2019

AbstractThe IAU is like an old house: Each of the IAU General Secretaries brings her/his individual skills, trying to fix it up. After the collective efforts of several General Secretaries, the house is hopefully kept in reasonable overall shape. But each General Secretary is also in principle responsible for everything, which means that priorities for the way you spend your time must be set – remembering that surprises may occur at any moment.In my case, I’d like to single out five major initiatives taken during my term, which have probably proved useful in the longer term.
Serving Astronomy: the Aim of the IAU
Authors: Baneke David , Andersen Johannes , Madsen Claus 
Published: April 2019

AbstractThe IAU was founded in 1919“to facilitate the relations between astronomers of different countries where international co-operation is necessary or useful” and “to promote the study of astronomy in all its departments”. These aims have led the IAU throughout the century of its existence, but the way it has tried to fulfil them has changed. We have tried to trace the changing role of the IAU in the international astronomical community through the twentieth century and into the twenty-first. The IAU has striven – occasionally struggled – to protect international scientific cooperation across the deep political divides that characterized the 20th century, while maintaining an important function in the context of the rapidly evolving science itself and the changing fabric of institutions involved in astronomy. We especially argue how the emphasis of the IAU’s activities has shifted from the first aim – facilitating collaboration by organizing meetings and defining common standards – to the second aim: promoting astronomy by outreach and development programs.
George Ellery Hale’s Internationalism
Authors: DeVorkin David 
Published: April 2019

AbstractThroughout his career, George Ellery Hale thought globally. “Make no small plans” he was often heard to say (Seares 1939). His early sojourns to Europe, encountering the talent and resources in England and the Continent, contributed to his outlook. He knew that their patronage was critical to reach his personal goals. Here I outline the steps Hale took to establish the new “astrophysics” as a discipline, by creating the Astrophysical Journal, establishing a common language and then, through the first decades of the 20th Century, building an international collaboration to coordinate solar and later all astronomical research. The latter effort, which began in 1904, had expanded by 1910 to encompass stellar astronomy, when the Solar Union deliberated over spectroscopic classification systems, a standard wavelength system and stellar magnitude systems. This work continued through the fifth Union meeting in Bonn in 1913, which turned out to be the last because of the First World War. During the war, Hale became Chair of the National Research Council of the U.S. National Academy of Sciences, applying scientific talent to winning the war. He was also the Academy’s Foreign Secretary, so Hale became deeply involved in re-establishing international scientific relations after the war. In conjunction with Arthur Schuster and Emile Picard, he helped found the International Research Council in 1919, which formed the framework within which the worlds of science reorganized themselves. From this, the International Astronomical Union was born. It was not an easy birth in a world still filled with tension and anger over the war; formative conferences in London and Brussels reflected the extremes. Nevertheless, its first General Assembly was held in Rome in 1922. It would be years before it became truly international, “in the complete sense of the word” (Elis Strömgren), but many of the proposals made during the years of the Solar Union concerning disciplinary standardization were ratified. I will concentrate on this latter story, remembering Hale for his devotion to true internationalism.
Italian Astronomers in the IAU: the contribution and role of Italian astronomers from the foundation to the Second World War
Authors: Zanini V. , Gargano M. , Gasperini A. 
Published: April 2019

AbstractEven though Italy officially joined the IAU in 1921, Italian astronomers were involved in its birth as early as 1919, when Annibale Riccò, Director of the Astrophysical Observatory of Catania, proposed to the IAU Committee to hold its first General Assembly in Rome. This contribution will analyze the role played by Italian astronomers in the development of the IAU from its foundation to the Second World War. The recent project of reordering of the astronomical historical archives in Italy permits for the first time a more in-depth study of the relations between Italian astronomers and the international scientific community.
Progress of Radar Observations of Meteors in Kazan (Russia) over the Last Sixty Years
Authors: Kalabanov Sergei A. , Karpov Arkadiy V. , Sulimov Amir I. , Sherstyukov Oleg N. , Ishmuratov Rashid A. 
Published: April 2019

AbstractThis paper presents a brief survey on the history of radar observations of meteors in Kazan from 1950s to present days. Such achievements of Kazan researchers as development and further improvement of original measuring equipment and antenna systems, of observational data processing methods, their contribution to the theory of physics of meteor phenomena and theoretical interpretation of experimental data are highlighted. A particular progress in meteor astronomy has been achieved with a new discrete quasi-tomoghraphic method for faint meteor showers identification that uses goniometer data of meteor radio reflections detected on radar as input data. The current state and new horizons of meteor studies in Kazan are stated.
Commission 38 (Exchange of astronomers) and Commission 46 (Teaching of astronomy): two commissions that played a unique role in the history and development of the IAU
Authors: Hearnshaw John B. 
Published: April 2019

AbstractThe founding and development of two commissions of the IAU that played a unique role in IAU history are traced. Commission 38 for the Exchange of astronomers was founded in 1946 with Frederick Stratton as first president, and it expended funds (initially granted by UNESCO) for astronomers to travel on exchange visits. Commission 46 for the Teaching of astronomy was founded in 1964 with Evry Schatzmann as first president. This was a time of rapidly growing interest in the IAU for teaching astronomy and in due course for promoting astronomy in developing countries. For a while, both commissions operated under the wing of the Executive Committee. Their role was unique as they were the only IAU commissions to have their own budget, as well as aspiring to bring about social change in the astronomical community. By 2000 both commissions merged into C46 (Astronomy education and development) and by that time various programmes such as the International School for Young Astronomers (ISYA), the working group World-wide Development of Astronomy (WWDA) and the working group Teaching Astronomy for Development (TAD), which grew out of the Visiting Lecturers’ Program (VLP), were all run by C46. When the IAU established the Office of Astronomy for Development in 2011, many of these functions were removed from the commission and in any case C46 ceased to exist in 2015 when all the old commissions were disestablished. In 2015 the Office for Young Astronomers took over the running of the ISYA. The history of C38 and C46 represents a time of active change in the way the IAU was engaging with people. It was more than just a union for scientific research, but in the world of scientific unions, it was remarkable for taking an active hands-on role in implementing social change. In the history of these two commissions, the Swiss astronomer Edith Müller played a leading dynamic role. She served as president of C46 (1967-73), of C38 (1985-88) as well as IAU General Secretary (1976-79).
A history of IAU Commission C1: a look from the Newsletters
Authors: Bretones Paulo S. 
Published: April 2019

AbstractThis work aims to present the partial results of a project to collect and analyze all the issues of the Newsletters of Commission C1 (Astronomy Education and Development), formerly named Commission 46. The sources and the (hard) work to obtain printed editions, digitalize and make them available on the Internet are shown. Over 40 years, 86 issues from 1977 until 2017 were published. The Newsletters list the structure of the Commission featuring the names of presidents, vice-presidents, organizing committee, editors, printing and distribution responsible with editorial and presidential letters in the cover. A preliminary analysis of contents of the published material is done. The results present the main subjects of stories that were related to papers, teaching materials, book reviews, courses and meetings. Many solar eclipses and other phenomena were reported. Reports of important projects of the commission were published, such as: International Schools for Young Astronomers (ISYAs), the travelling telescope among others WG projects. Stories of travels and triennial reports from many countries were continuously published presenting many actions and activities for all school levels, non-school activities such as planetariums and many other astronomy subjects. Reports of the education sessions and business meetings held during the IAU GAs and projects in developing countries complemented these publications. Occasionally, papers dealing with great questions and subjects can be found. There are many published contributions that show the participation of many members from many countries and the efforts to improve the astronomy education throughout the world. The surveyed material can be very useful for the next generations of astronomy education researchers, practitioners and teachers, not only as a repository of historical documents, but also as an inspiration for future projects.

Sciences and audiences along the last century: the impact of Astronomy Education
Authors: Ros Rosa M. , Garca Beatriz 
Published: April 2019

AbstractJust as in the past, the development of the natural sciences and in particular of astronomy has changed the history of humanity. If we think about the role of our discipline into the future, it shows its enormous power in the field of education, owing to the possibility of awakening interest in science in very varied audiences. Within the framework of the enormous progress made in the technologies related to astronomy, many of them of daily use, the role of the astronomer in the era of Communications acquires fundamental importance.In this presentation, we will try to make a journey through the different ways of presenting astronomical topics for different audiences over the last 100 years. In turn, we will show some specific achievements, associated with education programmes of the discipline. We discuss the impact produced by proposals that are both rigorous in terms of content, and also appeal to the development of the human being in an integral manner, within the framework of citizen science activities.For this research, we have taken into account the uninterrupted development of the NASE programme, which has performed 112 courses in 24 countries throughout the world and in different languages. NASE has involved 4966 secondary teachers in the last eight years.
Under One Sky: the IAU and Women in Astronomy
Authors: Griffin Elizabeth 
Published: April 2019

AbstractOf all the sciences, astronomy is by far the most border-less in its activities, and the most advanced in its concepts of collaborating across borders. In their dealings and in their needs, today’s teams are mature enough to ignore gender differences and ethnic differences, and across the past 50+ years of IAU membership which I personally can chalk up, the IAU personnel, Commissions, and other bodies have come to reflect more nearly the same – albeit small – gender ratios as found in its member institutions. In the IAU there has always been space for the individual, and if one recalls the early contributions to the IAU by major players like Edith M¨uller, Giusa Cayrel, Anne Underhill and Charlotte Moore, I think it can be said that astronomy was, and knew it was, better off by giving such people the latitude that they deserved as scientists, rather than because they were women. When a meeting in Baltimore in 1992 was called to discuss “Women in Astronomy”, the pressure came from the younger generations, who feared that the low percentages of tenured women in astronomy would be allowed to continue unnoticed, so they created the Baltimore Charter to draw attention to what certainly appeared to some as discrimination. Even though there could be no quick fixes to the situation, and the winds of change have been more like zephyrs than the cleansing gales that some hoped for, the percentage of women now rising through the ranks is definitely on the increase, and is witnessing growing ethnic diversity. Those are a matter of pride for the IAU, and must be highlighted in this its Centenary Year.
Structural Hindrances or Less Driven Women? Managers’ Views on Corporate Quotas

Published: April 2019

AbstractHigh levels of women in politics and paid work, together with the availability of paid parental leave and public child care, make the gender imbalance in business leadership in Iceland all the more confounding. This study analyzes business leaders’ attitudes toward gender and leadership positions after a gender quota law for company boards was implemented in 2013. We explore support for gender quotas and whether it is related to how respondents explain women's underrepresentation in leadership positions. A questionnaire was sent to 1,349 managers in the 250 largest companies in Iceland. Our findings indicate that women are more supportive of gender quotas than men. The way in which the respondents explain the underrepresentation of women as top managers is strongly related to their support for gender quotas. Those who believe that women are structurally disadvantaged are more likely to support gender quotas than those who adhere to individual explanations. Furthermore, male dominance at higher company levels is related to negative views on gender quotas, whereas this does not apply at lower levels. The research emphasizes the impact of business leaders on the recruitment of women to business leadership positions and, at the same time, has implications for policy interventions.

Published: April 2019

Abstract. Background: Although there are some reports on the association of dietary patterns and chronic kidney disease (CKD), no data exists regarding the relation between dietary pattern and CKD from developing countries. Objective: To examine the association between major dietary patterns, renal function and progression of CKD. Methods: Two hundred twenty one subjects with diagnosed CKD were selected for this cross-sectional study. Dietary intake of patients was assessed by a validated food frequency questionnaire. Major dietary patterns were extracted by factor analysis. Renal function was measured by blood urea nitrogen (BUN) and serum creatinine (Cr) level as well as estimated glomerular filtration rate (eGFR). Results: Three major dietary patterns were identified: high fruits and vegetables, high simple carbohydrate and sugar and high fat. Subjects in the second quartile of high fat dietary pattern score had lower Cr and higher eGFR in compared with the first quartile after adjusting for covariates (P = 0.02 for both). After adjusting for confounders (age, physical activity, socioeconomic status, height, weight, systolic and diastolic blood pressure and energy intake), patients in the top quartile of high fat dietary pattern score were found to be at greater risk of being in the higher stages (stage 3 vs. stages 4 and 5) of CKD (odds ratio: 3.09; 95% CI: 1.23, 7.76; P for trend = 0.02). Conclusion: We observed that a high fat dietary pattern was directly associated with progression of CKD.

Published: April 2019

Abstract. Background: Nonalcoholic fatty liver disease (NAFLD) is a serious global health problem, thus the prevention and management of the disease is necessary. This study aimed to determine the effects of Ramadan Fasting (RF) on liver function, Visceral Adiposity Index (VAI) and Atherogenic Index of Plasma (AIP) in these patients. Methods: Eighty-three NAFLD patients (57 males and 26 females) were enrolled in the study, 42 patients who practiced RF, between Jun 18 through July 17, 2015 and 41 patients in non-fasting groups. Anthropometric parameters and Ultrasound grading were measured before and after Ramadan. The biochemical parameters including lipid profiles (total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides), liver enzymes (Aspartate aminotransferase, SGOT and Alanine aminotransferase, SGPT) were evaluated before and after Ramadan. AIP and VAI were calculated based on formula. Results: The mean decreases in anthropometric indices were significantly different between groups. Similarly, the mean decrease in the total cholesterol values in the fasting group was remarkably greater than in the control group (p = 0.02). The values of AIP and VAI decreased at the end of the study in both group and the mean of changes showed no differences between groups (p = 0.79 and p = 0.65 for AIP and VAI, respectively). The changes in the concentrations of liver enzymes, as well as the severity of hepatic steatosis, showed remarkable differences between groups (p = 0.03, p = 0.05, and p = 0.02 for SGOT and SGPT, and Liver steatosis, respectively). Conclusion: RF improved liver steatosis in NAFLD patients and might be useful in the management of NAFLD.
Convective Self‐Aggregation As a Cold Pool‐Driven Critical Phenomenon
Authors: Haerter Jan O. 
Published: April 2019

AbstractConvective self‐aggregation is when thunderstorm clouds cluster over a constant temperature surface in radiative convective equilibrium. Self‐aggregation was implicated in the Madden‐Julian Oscillation and hurricanes. Yet, numerical simulations succeed or fail at producing self‐aggregation, depending on modeling choices. Common explanations for self‐aggregation invoke radiative effects, acting to concentrate moisture in a subdomain. Interaction between cold pools, caused by rain evaporation, drives reorganization of boundary layer moisture and triggers new updrafts. We propose a simple model for aggregation by cold pool interaction, assuming a local number densityρ(r) of precipitation cells, and that interaction scales quadratically withρ(r). Our model mimics global energy constraints by limiting further cell production when many cells are present. The phase diagram shows a continuous phase transition between a continuum and an aggregated state. Strong cold pool‐cold pool interaction gives a uniform convective phase, while weak interaction yields few and independent cells. Segregation results for intermediate interaction strength.
The Magnetic Local Time Distribution of Storm Geomagnetic Field Disturbance Under Different Conditions of Solar Wind and Interplanetary Magnetic Field
Authors: Liu Bao‐Jia , Zhang Xiao‐Xin , He Fei , Zong Qiu‐Gang 
Published: April 2019

AbstractThe magnetic local time (MLT) distributions of the horizontal geomagnetic disturbance (∆H) are investigated with the SuperMAG data set during 330 magnetic storms from 2000 to 2015. Then the MLT distributions of ∆H are verified and interpreted with the SuperMAG‐based partial ring current indices (SMR indices) and the Burton equation. It is shown that the ∆H is positive at most MLTs and slightly stronger on the dayside during the initial phase. Such distribution might be mainly attributed to the global positive impact of the magnetopause currents, while the ring current (RC) only produces weak negative disturbances, which are slightly stronger on the duskside. In the main phase, the ∆H decreases prominently with the peak on the duskside. The RC particles injection plays a major role, especially for large solar wind electric field (ESW). The region with ∆H larger than −20 nT is concentrated on the dawnside for small ESW, which might be attributed to earthward bursty bulk flows. Besides, larger solar wind dynamic pressure might cause stronger disturbances under the same magnitude of ESW. In the recovery phase, the ∆H is weaker and more uniform distributed than in the main phase for negative ESW. For positive ESW, similar dawn‐dusk asymmetry occurs as that in the main phase, but the peak of strongest disturbance tends to weaken and move toward the dayside. Based on the dawn‐dusk asymmetric decay rate derived from the Burton equation, it is speculated that the contribution of partial RC might be no less than the FACs.
