Alice Miel and Democratic Schooling: An Early Curriculum Leader\u27s Ideas on Social Learning and Social Studies
Get PDFAlice Miel, a nationally prominent curriculum development scholar-practitioner at Teachers College of Columbia University for some three decades (1942-1971), frequently has been overlooked in research on the nature and evolution of the curriculum field and the progressive education movement. Furthermore, her contributions have been overlooked even as attention to women in the curriculum field and in educational history has risen. This study addresses this oversight.
Miel became a leading figure in the curriculum field largely on the basis of her progressive-era advocacy and practice of democratic social learning as a primary goal of schooling in the United States. This study explores major influences on her ideas, her understandings of democratic concepts and principles, and her application of these concepts and principles both in her own college classroom and in her research on childhood education. It also explores Miel\u27s notions of the elementary school social studies :urriculum and situates those notions within the context of the conventional wisdom of her day regarding a discipline-centered curriculum.
In a broader context, this study contributes to the body of curriculum history scholarship. According to Kliebard (1992), for example, curriculum history often deals with the relationship between social change and changing ideas and contains significant social and cultural artifacts of knowledge that have become embodied in the curriculum of schools. Davis (1976, 1977) characterizes curriculum history as a reflective enterprise for curriculum workers that contributes to their understanding of present courses of study and of the professional field by lending a framework for thoughtful deliberation of what the schools should teach. With these observations in mind, Miel\u27s work may be understood as both artifact of curriculum history and as mindful reflection, situated within a particular social and historical context, on democratic meanings and processes. Biographies of Caswell, Taba, Tyler, Schwab, Kilpatrick, Rugg, Bobbitt, Zirbes, Stratemeyer, and others have yielded significant insights. In addition, Seguel\u27s study of early curriculum leaders (1966) constitutes an important theoretical contribution to the field. The study of Miel\u27s life and work adds to this body of knowledge

Recent resonance results measured with the ALICE detector at the LHC
No full textResonances are extremely short lived particles (τ ∼ 10-23 s). Due to their lifetime, they may decay, re-scatter and regenerate between chemical and kinetic freeze-outs. For this reason, they are very significant probes to understand the evolution of the medium and particle production mechanism in heavy ion collisions. Different than other particles, resonance properties such as mass, width and yield can be modified by the medium created in the relativistic collisions. Moreover, comparison of resonances produced in different collisions provide evidences about possible in medium effects and system size dependency of their production. ALICE (A Large Heavy Ion Experiment) is one of the detectors at the LHC specifically designed to investigate the features of the quark gluon plasma (QGP). In this proceeding, the recent ALICE resonance results in pp, p-Pb and Pb-Pb collisions at the LHC energies are presented. © 2017 Author(s)
The ALICE experiment: a journey through QCD
No full textThe ALICE experiment was proposed in 1993, to study strongly-interacting matter at extreme energy densities and temperatures. This proposal entailed a comprehensive investigation of nuclear collisions at the LHC. Its physics programme initially focused on the determination of the properties of the quark–gluon plasma (QGP), a deconfined state of quarks and gluons, created in such collisions. The ALICE physics programme has been extended to cover a broader ensemble of observables related to Quantum Chromodynamics (QCD), the theory of strong interactions. The experiment has studied Pb–Pb, Xe–Xe, p–Pb and pp collisions in the multi-TeV centre of mass energy range, during the Run 1–2 data-taking periods at the LHC (2009–2018). The aim of this review is to summarise the key ALICE physics results in this endeavor, and to discuss their implications on the current understanding of the macroscopic and microscopic properties of strongly-interacting matter at the highest temperatures reached in the laboratory. It will review the latest findings on the properties of the QGP created by heavy-ion collisions at LHC energies, and describe the surprising QGP-like effects in pp and p–Pb collisions. Measurements of few-body QCD interactions, and their impact in unraveling the structure of hadrons and hadronic interactions, will be discussed. ALICE results relevant for physics topics outside the realm of QCD will also be touched upon. Finally, prospects for future measurements with the ALICE detector in the context of its planned upgrades will also be briefly described. © The Author(s) 2024
Extending the ALICE strong-interaction studies to nuclei: measurement of proton-deuteron correlations in pp collisions at √s 13 TeV
No full textSissa Medialab SrlThe large data sample of high-multiplicity pp collisions collected by ALICE allows for the precise measurement of the size of source producing primary hadrons, opening the doors to a study of the interaction of different hadron species using femtoscopy techniques. The momentum correlation between (anti)protons and (anti)deuterons measured in pp collisions at √s 13 TeV with ALICE is studied here for the first time. The measured correlation function for ((equation presented))p-((equation presented))d pairs is compared with theoretical predictions obtained considering Coulomb and Coulomb plus strong interactions and employing the Lednický-Lyuboshitz model with scattering parameters extracted from traditional scattering experiments for the p-d system. The measured correlation function can not be reproduced by any of the obtained predictions. This deviation can to large extent be interpreted as a demonstration of the late formation time of (anti)deuterons in hadron-hadron collisions. This observation is key for the understanding of the production mechanism of light (anti)nuclei, which is an open issue in high-energy physics and has also important consequences for the study of antinuclei formation in the interstellar medium either from collisions triggered by high-energy cosmic rays or by dark matter decays. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0
Measurement of the production of high-p(T) electrons from heavy-flavour hadron decays in Pb-Pb collisions at root s(NN)=2.76 TeV
Get PDFElectrons from heavy-flavour hadron decays (charm and beauty) were measured with the ALICE detector in Pb-Pb collisions at a centre-of-mass of energy root s(NN) = 2.76 TeV. The transverse momentum (pT) differential production yields at mid-rapidity were used to calculate the nuclear modification factor R-AA in the interval 3 <p(T) <18 GeV/c. The R-AA shows a strong suppression compared to binary scaling of pp collisions at the same energy (up to a factor of 4) in the 10% most central Pb-Pb collisions. There is a centrality trend of suppression, and a weaker suppression (down to a factor of 2) in semi-peripheral (50-80%) collisions is observed. The suppression of electrons in this broad p(T) interval indicates that both charm and beauty quarks lose energy when they traverse the hot medium formed in Pb-Pb collisions at LHC.

Conceptual design of an ALICE Tier-2 centre integrated into a multi-purpose computing facility
No full textThis thesis discusses the issues and challenges associated with the design and operation of a data analysis facility for a high-energy physics experiment at a multi-purpose computing centre. At the spotlight is a Tier-2 centre of the distributed computing model of the ALICE experiment at the Large Hadron Collider at CERN in Geneva, Switzerland. The design steps, examined in the thesis, include analysis and optimization of the I/O access patterns of the user workload, integration of the storage resources, and development of the techniques for effective system administration and operation of the facility in a shared computing environment. A number of I/O access performance issues on multiple levels of the I/O subsystem, introduced by utilization of hard disks for data storage, have been addressed by the means of exhaustive benchmarking and thorough analysis of the I/O of the user applications in the ALICE software framework. Defining the set of requirements to the storage system, describing the potential performance bottlenecks and single points of failure and examining possible ways to avoid them allows one to develop guidelines for selecting the way how to integrate the storage resources. The solution, how to preserve a specific software stack for the experiment in a shared environment, is presented along with its effects on the user workload performance. The proposal for a flexible model to deploy and operate the ALICE Tier-2 infrastructure and applications in a virtual environment through adoption of the cloud computing technology and the 'Infrastructure as Code' concept completes the thesis. Scientific software applications can be efficiently computed in a virtual environment, and there is an urgent need to adapt the infrastructure for effective usage of cloud resources
