From hanging out to figuring it out: Socializing online as a pathway to computational thinking

Although socializing is a powerful driver of youth engagement online, platforms struggle to leverage social engagement to promote learning. We seek to understand this dynamic using a multi-stage analysis of over 14,000 comments on Scratch, an online platform designed to support learning about programming. First, we inductively develop the concept of “participatory debugging”—a practice in which users learn through the process of collaborative technical troubleshooting. Second, we use a content analysis to establish how common the practice is on Scratch. Third, we conduct a qualitative analysis of user activity over time and identify three factors that serve as social antecedents of participatory debugging: (1) sustained community, (2) identifiable problems, and (3) what we call “topic porousness” to describe conversations that are able to span multiple topics. We integrate these findings in a framework that highlights a productive tension between the desire to promote learning and the interest-driven sub-communities that drive user engagement in many new media environments.

Over Time

Abstract The classical senses (vision, hearing, touch, taste, and smell) play a key role in social function by allowing interaction and communication. We assessed whether sensory impairment across all 5 modalities (global sensory impairment [GSI]) was associated with social function in older adults. Sensory function was measured in 3,005 home-dwelling older U.S. adults at baseline in the National Social Life, Health, and Aging Project and GSI, a validated measure, was calculated. Social network size and kin composition, number of close friends, and social engagement were assessed at baseline and 5- and 10-year follow-up. Ordinal logistic regression and mixed effects ordinal logistic regression analyzed cross-sectional and longitudinal relationships respectively, controlling for demographics, physical/mental health, disability, and cognitive function (at baseline). Adults with worse GSI had smaller networks (β=-0.159, p=0.021), fewer close friends (β=-0.262, p=0.003) and lower engagement (β=-0.252, p=0.006) at baseline, relationships that persisted at 5 and 10 year follow-up. Men, older people, African-Americans, and those with less education, fewer assets, poor mental health, worse cognitive function, and more disability had worse GSI. Men and those with fewer assets, worse cognitive function, and less education had smaller networks and lower engagement. African-American and Hispanic individuals had smaller networks and fewer close friends, but more engagement. Older respondents also had more engagement. In summary, GSI independently predicts smaller social networks, fewer close friends, and lower social engagement over time, suggesting that sensory decline results in decreased social function. Thus, rehabilitating multisensory impairment may be a strategy to enhance social function as people age.

The 1950S

The article presents some historical and theoretical aspects defining intermedia as an aesthetic, cultural and social phenomenon. Its appearance in the 1950s and 1960s was triggered by the changed attitude towards art in the conditions of growing technology in society and the blurring of boundaries between different arts. The concept of intermedia is created by a group of artists who unite under the common name Fluxus, meaning „ flow of life“. Group Manifesto – Dick Higgins, composer, poet, publisher - formulates intermedia as a merger into a „ flow“ of different ways of artistic expression and means of communication. The most important distinctive features of intermedia – accessibility, non-commerciality, freedom, social engagement, compliance of modern lifestyle and the new media in it are traced. It explains the role of this aesthetic practice as an instrument in creating the hypertext of contemporary art.

Turbomachinery Design

The prediction of aerodynamic blade forcing is a very important topic in turbomachinery design. Usually, the wake from the upstream blade row and the potential field from the downstream blade row are considered as the main causes for excitation, which in conjunction with relative rotation of neighboring blade rows, give rise to dynamic forcing of the blades. In addition to those two mechanisms so-called Tyler-Sofrin (or scattered or spinning) modes, which refer to the acoustic interaction with blade rows further up- or downstream, may have a significant impact on blade forcing. In particular, they lead to considerable blade-to-blade variations of the aerodynamic loading. In part 1 of the paper a study of these effects is performed on the basis of a quasi 3D multi-row and multi-passage compressor configuration. Part 2 of the paper proposes a method to analyze the interaction of the aerodynamic forcing asymmetries with the already well-studied effects of random mistuning stemming from blade-to-blade variations of structural properties. Based on a finite element model of a sector, the equations governing the dynamic behavior of the entire bladed disk can be efficiently derived using substructuring techniques. The disk substructure is assumed as cyclically symmetric, while the blades exhibit structural mistuning and linear aeroelastic coupling. In order to avoid the costly multi-stage analysis, the variation of the aerodynamic loading is treated as an epistemic uncertainty, leading to a stochastic description of the annular force pattern. The effects of structural mistuning and stochastic aerodynamic forcing are first studied separately and then in a combined manner for a blisk of a research compressor without and with aeroelastic coupling.

Education era 4.0 requires output that has top 10 skills 2020. One of the strategies needed in era 4.0 education is a Self Access Center (SAC) that focuses on children's self reliance in learning in elementary school. SAC is one of exploration of children's reliance independently in developing capabilities needed in the industrial era 4.0. The purpose of this study was to describe the reliance of children in learning an elementary school through a SAC in developing top 10 skills 2020. The method used in this study was descriptive qualitative. The results of the analysis show that the SAC can contribute. This is indicated by the achievement of the SAC has reached seven out of ten top skills, namely sense making, social intelegence, cross cultural competency, novel and adaptive thinking, transdiciplinary, computational thinking, and new media literacy and to be able to adjust to top 10 skills 2020 a better strategy is needed to achieve 10 skills with cognitive load management, design mindset and virtual collaboration.

With the rise of neoliberalism, postfeminism and “hookup culture,” young women face both challenges and opportunities when constructing themselves as sexual subjects. This paper explores the experiences of a young woman who sought to have sex with someone new in order to move on from the breakup of a long-term relationship. This case study is part of a larger project which explored how young people (aged 18–25) negotiate their love/sex relationships within the context of new media environments. While this young woman described her experience of having sex with someone new as “empowering,” within a neoliberal, postfeminist context the concept of empowerment may not be a useful theoretical tool for understanding young women’s sexuality. Situating her story within its broader sociocultural context, this paper explores how structural factors shape this young woman’s ability to navigate normative discourses about sexual empowerment and construct herself as a sexual subject.

Over Time

Myelodysplastic syndromes (MDS) are a heterogeneous group of hematopoietic neoplastic diseases characterized by inefficient hematopoiesis, resistant peripheral cytopenias and an increased risk of transformation to acute myeloid leukemia. They may exist as primary forms, which most often are accompanied by molecular and cytogenetic changes or secondary forms, among others after chemotherapy or other cancers. MDS diagnostics are multi-stage and time-consuming. Includes multidirectional examination of peripheral blood and bone marrow for cytomorphology, cytogenetics, molecular disorders, immunohistopatology and immunophenotyping. The evolution of molecular changes in the course of MDS makes the clinical picture and laboratory parameters change over time, which requires constant updating of medical knowledge and high competences from cytomorphologists and histopathologists. The development of hematooncological diagnostics resulted in updating the MDS classification in 2016. The aging population will undoubtedly increase the incidence of myelodysplastic syndromes, which will be one of the most demanding diagnostic and clinical problems for haematologists and laboratory diagnostics in the near future.
