The Katonah Museum of Art is a non-collecting institution geared towards visual arts, located in Katonah, New York. The museum presents changing exhibitions that cross a spectrum of artistic disciplines, cultures, and historical periods. With each exhibition, artists, curators, and other specialists present art through programs, lectures, and workshops designed for visitors of all ages. The Museum's Learning Center uses a visual and interactive environment that encourages children and their parents to participate in hands-on projects. The Katonah Museum also offers outdoor concerts, evening cocktail parties, international travels, and trips to other museums and private collections..
We examine the spatial distribution of star clusters in NGC628 using the statistical tool INDICATE to quantify clustering tendencies. Our sample, based on Hubble Space Telescope and James Webb Space Telescope observations, is the most complete to date, spanning ages from 1 to >100 Myr. We find cluster spatial behaviour varies with galactic position, age, and mass. Most emerging young clusters are tightly spatially associated with each other, while fully emerged clusters are in similar to 1.5 times looser spatial associations, irrespective of age. Young Massive Clusters ( (YMCs >= 10(4)M(circle dot)) tend to associate with lower-mass clusters but not strongly with other YMCs, implying that intense star formation regions produce a few YMCs alongside many lower-mass clusters rather than multiple YMCs together. Young concentrated clusters show a wide radial distribution in the galactic disc, which narrows with age; with concentrated clusters > 100 Myr mostly residing between 2 and 6 kpc. This pattern may reflect either faster dispersal of isolated tight cluster spatial 'structure' in a lower gas density outer disc or gradual inside-out growth, with the formation of this structure shifting outwards over time. We also detect distinct spatial behaviours for clusters within 2 kpc, linked to the inner Lindblad resonance (<= 1 kpc), nuclear ring (similar to 0.5-1 kpc), and the start of spiral arms (similar to 1.25-2 kpc), suggesting these regions exhibit strong radial motions that could hinder clusters from forming and remaining in tight concentrations. Our results highlight how spatially resolved studies of clusters can reveal the influence of galactic dynamics on star formation and cluster evolution.
Museum educators and instructors of English as a Second Language (ESOL) at a community college in New York reflect on their experiences facilitating a program designed to enrich the language, cultural, and visual literacy skills of adult immigrant students. The CALTA21 program brought together three stakeholders, immigrant ESOL students, language instructors, and museum educators in collaboration to build linguistic, social, and cultural capital. A professional development institute, utilizing Visual Thinking Strategies as a core pedagogy, provided a common practice used by the stakeholders in the classroom and the museum. This democratic method subverted the traditional student-teacher relationship by using inquiry and personal narratives to inspire an exchange of ideas. The case study will consider the elements of the program that supported the development of a dynamic community of learners, and the empowering experience of teaching and learning within a model of shared authority.
An extreme-rainfall-producing mesoscale convective system (MCS) associated with the Changma front in southeastern South Korea was investigated using observational data. This event recorded historic rainfall and led to devastating flash floods and landslides in the Busan metropolitan area on 7 July 2009. The aim of the present study is to analyse the influences for the synoptic and mesoscale environment, and the reasons that the quasi-stationary MCS causes extreme rainfall. Synoptic and mesoscale analyses indicate that the MCS and heavy rainfall occurred in association with a stationary front which resembled a warm front in structure. A strong southwesterly low-level jet (LLJ) transported warm and humid air and supplied the moisture toward the front, and the air rose upwards above the frontal surface. As the moist air was conditionally unstable, repeated upstream initiation of deep convection by back-building occurred at the coastline, while old cells moved downstream parallel to the convective line with training effect. Because the motion of convective cells nearly opposed the backward propagation, the system as a whole moved slowly. The back-building behaviour was linked to the convectively generated cold pool and its outflow boundary, which played a role in the propagation and maintenance of the rainfall system. As a result, the quasi-stationary MCS caused a prolonged duration of heavy rainfall, leading to extreme rainfall over the Busan metropolitan area.
Born in Neuchâtel, Switzerland, Jean William Fritz Piaget pioneered the field of cognitive developmental psychology using empirical methods to study children. Like Walter Benjamin, Piaget was one of the few modern thinkers to take children seriously, and his enduring impact is attested by the fact that he is the second most cited psychologist in the twentieth century after Sigmund Freud. A precocious student, who had published his first scientific article at the age of ten, Piaget received his doctorate in zoology at the age of twenty-two.
