    No full text
    SUMMARY: In this interview, Washington, D.C. native Alisa Hill speaks about the phenomenon of homelessness in the city. Alisa shares her personal experiences with homelessness, including her efforts to find shelter and how being homeless has affected her relationships with others. Alisa also discusses her advocacy efforts to bring attention to the issue of homelessness and her outreach with homeless children. PROJECT’S OBJECTIVES: The interviews conducted as part of the DC Oral History and Social Justice Project record how unhoused residents of the greater DC area view the history of homelessness – how did homelessness become such an entrenched part of the city. The interviews will be used to create critical dialogue among people who are currently unhoused in Washington, DC, and then they may be used to assist future advocacy efforts

    A “very decent nick”: ethical treatment in prison-based democratic therapeutic communities

    No full text
    The penal system of England and Wales has been greatly influenced in the past two decades by the emergence of a moral framework or ‘decency agenda’. What decency means to prisoners and how decency can be embodied into daily prison life, however, remains underexplored. Drawing from her original research in prison-based democratic therapeutic communities (TCs), the author argues that decency is experienced in TCs through an ethic of care and an ethos of change. TC residents benefit from atypical institutional practices which encourage the formation of supportive relationships with prison staff and facilitate meaningful opportunities for personal change

The aim of the bachelor's thesis was to create an author's photography project on the tradition of writing paper letters in order to draw the public's attention to the shortcomings of modern forms of communication, as well as to popularize such a tradition as writing a paper letter. The bachelor's thesis consists of a theoretical part and a conceptual part. In order to achieve the goal of the final work, the following tasks were set. The theoretical part of the work deals with the concept of photography and self-photography, as well as the study of the visual representation of paper letters. The concepts of communication and verbal communication, the concept of a paper letter and their properties, as well as the properties of communication with paper letters were examined and a study of the concept of tradition was carried out. In the part of the work concept, a description of the creative work concept design development was made, which includes the course of the photo series, the process of taking photos and a description of their post-processing. Conclusions were drawn at the end of the work. Keywords: photography, communication, paper letter, tradition, visual representation, author photography

    Agency in Teacher Supervision and Mentoring

    Offering an in-depth examination of field supervision and the role of the university supervisors in preparing teachers, this book addresses the challenges of providing novice teachers with quality supervision through the support and guidance of teacher education programs. Through a research-based lens, Bates and Burbank discuss the role, responsibilities, and opportunities of the university supervisor. Critically examining the supervisor as an agent of change who is positioned to empower early career teachers, the authors dissect the necessary preparation and support new teachers need in contemporary K-12 classrooms

    Rheological properties of granular materials: critical parameters and mixing rules

    No full text
    Granular materials can be found at any stage of processing in many industries, such as food, pharmaceuticals, catalysts, and chemicals. These materials exhibit a variety of flow patterns, and their state and behavior differ from application to application. Since there is a lack of fundamental understanding of particulate or powder behavior, multiple problems can be encountered during routine manufacturing. Scale-up can also be a challenge, as the lack of constitutive equations for granular materials forces most scale-up efforts to follow the trial-and-error route. Powder characterization measurements are employed as both a selection tool and a predictive method for the material's process performance. Therefore, it plays a very important role in process and product development. The numerous existing methods used to characterize the flow properties of powders are mostly application-specific and it is not clear how they correlate with each other or with process performance. Moreover, understanding the relationships between the material properties and the processing conditions is necessary for a successful design of a continuous manufacturing system, which has been a major focus for pharmaceutical industry in the recent years. Before such changes can be implemented, a better understanding of fundamental physical phenomena governing powder flow behavior must be developed. In this work we study particulate/powder flow behavior experimentally using several characterization methods, including the Gravitational Displacement Rheometer (an avalanching tester), the rotational shear cell, and the compressibility tester. We establish the variables of interest through correlative comparison and study the differences and similarities between the methods in order to investigate particulate/powder flow behavior during processing and characterization. A mixing rule for principal stresses is developed through investigation of shear behavior of binary mixtures in a shear cell. In order to better understand the mixing rule the relationship between the particle-particle contact density and measured stresses in a powder bed is explored with DEM simulations. Powder testing methodologies were applied to a case study where the efficiency of the catalyst dry impregnation process was analyzed. As a result, predictive rules and characterization guidelines were developed for different powder systems subjected to various processing conditions.Ph.

    White Dwarf Stars and the Age of the Milky Way Researchers: Alisa Tiselska, Theodore von Hippel, Allison Woodruff, and Joey Hamill Faculty mentor: Theodore Von Hippel Abstract Author: Alisa Tiselska Our research objective is to determine the ages of the Milky Way’s stellar populations using our derived ages from thousands of white dwarf stars. Right ascension, declination, parallax, and proper motion values for known white dwarfs were taken from the Gaia Observatory database to calculate U, V, and W velocities relative to our position in the Galaxy. We wrote two codes —one in Matlab and one in Python — to assist with error propagation. Assuming that the input error distributions are Gaussian and that the transformations from the astrometric data to the U, V, and W velocities are sufficiently linear, we calculated the probability that each star belongs to the Galactic thin disk, thick disk, or halo. We are currently working on determining the ages of these star populations. The halo stars are the oldest of the three types; therefore, the average age of this population could give us an accurate estimate of the Milky Way’s age

    Dynamic Centrality for Directed Co-author Network with Context

    No full text
    Part 4: Data Analysis and Information RetrievalInternational audienceCo-author network is a typical example of dynamic complex network, which evolves and changes over time. One of the ways how to capture and describe the dynamics of the network is determination of Stationarity for detected communities in the network. In the paper, we have proposed the modified Stationarity, which is focused only on co-authors of a given author and not on the whole community to which the author belongs. Therefore, this modified Stationarity is defined for each author in the network and is perceived as dynamic centrality. The relations in homogeneous co-author network are not only set by the number of common publications, but are given by a context to terms used by the author extracted from the article titles. This dynamic centrality calculates with the evaluation by context of directed edges in co-author network. Such modified Stationarity gives us information about stability or dynamics of the author’s neighbourhood that influences her/him, or about the stability and dynamics of the author’s neighbourhood, which the author influences in relation to context

To view a copy of this license, visit http://creativecommons.org/licenses/by-nc-sa/3.0/.Background: α-Fetoprotein (AFP) is a tumour-associated antigen in hepatocellular carcinoma (HCC) and is a target for immunotherapy. However, there is little information on the pattern of CD4 (Th1) and CD8 (Tc1) T-cell response to AFP in patients with HCC and their association with the clinical characteristics of patients. Methods: We therefore analysed CD4 and CD8 T-cell responses to a panel of AFP-derived peptides in a total of 31 HCC patients and 14 controls, using an intracellular cytokine assay for IFN-γ. Results: Anti-AFP Tc1 responses were detected in 28.5% of controls, as well as in 25% of HCC patients with Okuda I (early tumour stage) and in 31.6% of HCC patients with stage II or III (late tumour stages). An anti-AFP Th1 response was detected only in HCC patients (58.3% with Okuda stage I tumours and 15.8% with Okuda stage II or III tumours). Anti-AFP Th1 response was mainly detected in HCC patients who had normal or mildly elevated serum AFP concentrations (P=0.00188), whereas there was no significant difference between serum AFP concentrations in these patients and the presence of an anti-AFP Tc1 response. A Th1 response was detected in 44% of HCC patients with a Child–Pugh A score (early stage of cirrhosis), whereas this was detected in only 15% with a B or C score (late-stage cirrhosis). In contrast, a Tc1 response was detected in 17% of HCC patients with a Child–Pugh A score and in 46% with a B or C score. Conclusion: These results suggest that anti-AFP Th1 responses are more likely to be present in patients who are in an early stage of disease (for both tumour stage and liver cirrhosis), whereas anti-AFP Tc1 responses are more likely to be present in patients with late-stage liver cirrhosis. Therefore, these data provide valuable information for the design of vaccination strategies against HCC.Association for International Cancer Research and Polkemmet Fund, London Clinic
