Direct combination: a new user interaction principle for mobile and ubiquitous HCI

Direct Combination (DC) is a recently introduced user interaction principle. The principle (previously applied to desktop computing) can greatly reduce the degree of search, time, and attention required to operate user interfaces. We argue that Direct Combination applies particularly aptly to mobile computing devices, given appropriate interaction techniques, examples of which are presented here. The reduction in search afforded to users can be applied to address several issues in mobile and ubiquitous user interaction including: limited feedback bandwidth; minimal attention situations; and the need for ad-hoc spontaneous interoperation and dynamic reconfiguration of multiple devices. When Direct Combination is extended and adapted to fit the demands of mobile and ubiquitous HCI, we refer to it as Ambient Combination (AC) . Direct Combination allows the user to exploit objects in the environment to narrow down the range of interactions that need be considered (by system and user). When the DC technique of pairwise or n-fold combination is applicable, it can greatly lessen the demands on users for memorisation and interface navigation. Direct Combination also appears to offers a new way of applying context-aware information. In this paper, we present Direct Combination as applied ambiently through a series of interaction scenarios, using an implemented prototype system

Administrative Leadership in Times of a Global Health Crisis: Voices and Images From the Field

The novel coronavirus (COVID-19) pandemic took the world into crisis. We saw the virus alter a multitude of spheres worldwide, including our healthcare, economies, politics, social processes, and education. In fact, the impact of COVID-19 on educational administration took our leaders into forced emergency measures. Our study aims to better understand the experiences of educational administrators under crisis to ascertain what might be learned on how educational institutions may better respond to the crisis in the future. These stories were collected from educational leaders, both from K-12 and higher education, throughout the United States. In brief, this article is framed in the theory and literature associated with the complexity of leading in times of crisis. We explore the resiliency of leadership forged in crisis and the rethinking of administrative as administration as a caring and trustful acts. Our research began as a hermeneutic phenomenological interview study, but transitions into a two-round project, where after the first interview, participants were invited to share some images that typify and speak to the experiences being educational administrators during this time. We are engaged in sensitive topics that are ongoing and changing. Moreover, throughout, we are asking for images that speak to their experiences. Across both K-12 and higher education, our results indicated varied responses, from immediate to delayed administrative action. However, albeit they looked contextually different, there are clear indications the participants valued continuous, transparent communication, authentic caring, trust, and agency. In our discussion, we elaborate on the distinction between what the institutional response was as compared to what was valued by our educational leaders. Finally, as a contribution to the field, we seek to provide guidance for future administrators in crisis based on our own experiences and the recommendations provided by our educational leaders

Who leads the leaders? K-12 and higher education leadership under duress

Beginning in March of 2020, the world of education was disrupted and potentially altered forever. This project considers the ways that leaders in both K-12 and higher education with the United States of America engaged in leadership to engage with their community. Using a two-part project, we worked with 15 educational leaders to better understand the impact that the COVID- 19 pandemic had on their work. In this paper, we outline the ways that these populations used their roles as educational leaders to provide aid, comfort, and voice for their communities. Using these experiences, we close with some recommendations to consider the ways that leadership can help their communities during times of crisis

Postfeminism, popular feminism and neoliberal feminism? Sarah Banet-Weiser, Rosalind Gill and Catherine Rottenberg in conversation

In this unconventional article, Sarah Banet-Weiser, Rosalind Gill and Catherine Rottenberg conduct a three-way ‘conversation’ in which they all take turns outlining how they understand the relationship among postfeminism, popular feminism and neoliberal feminism. It begins with a short introduction, and then Ros, Sarah and Catherine each define the term they have become associated with. This is followed by another round in which they discuss the overlaps, similarities and disjunctures among the terms, and the article ends with how each one understands the current mediated feminist landscape

Nod1 signaling overcomes resistance of S. pneumoniae to opsonophagocytic killing

Airway infection by the Gram-positive pathogen Streptococcus pneumoniae (Sp) leads to recruitment of neutrophils but limited bacterial killing by these cells. Co-colonization by Sp and a Gram-negative species, Haemophilus influenzae (Hi), provides sufficient stimulus to induce neutrophil and complement-mediated clearance of Sp from the mucosal surface in a murine model. Products from Hi, but not Sp, also promote killing of Sp by ex vivo neutrophil-enriched peritoneal exudate cells. Here we identify the stimulus from Hi as its peptidoglycan. Enhancement of opsonophagocytic killing was facilitated by signaling through nucleotide-binding oligomerization domain-1 (Nod1), which is involved in recognition of γ-D-glutamyl-meso-diaminopimelic acid (meso-DAP) contained in cell walls of Hi but not Sp. Neutrophils from mice treated with Hi or compounds containing meso-DAP, including synthetic peptidoglycan fragments, showed increased Sp killing in a Nod1-dependent manner. Moreover, Nod1-/- mice showed reduced Hi-induced clearance of Sp during co-colonization. These observations offer insight into mechanisms of microbial competition and demonstrate the importance of Nod1 in neutrophil-mediated clearance of bacteria in vivo

An Appreciative Approach to Diversity Training

One way to combat "diversity fatigue" is to take an appreciative approach to diversity training. This article highlights the six phases of Appreciative Education and how diversity trainers can use specific activities for each phase to deliver effective diversity training
