Guyana education access project: Baseline study
The Guyana Education Access Project (GEAP) is a large and complex five year project which has as its overall goal the provision of good quality secondary education for all children in two regions in Guyana, Corriverton (Region 10) and Linden (Region 6). The detailed project framework sets out the project’s objectives, inputs, activities and outputs. In addition, observable verifiable indicators have been clearly specified for all the projects key objectives.
A common failing of donor-funded education projects is that there is insufficient baseline information available that can be drawn upon at the end of the project in order to reach robust conclusions about project impacts in key areas. The GEAP project memorandum clearly stipulates therefore that a comprehensive baseline survey should be undertaken that will not only provide the basis for before- and after-project comparisons, but also can provide a valuable source of information for project monitoring.
The main purpose of this report is to: (i) identify a set of indicators which can be used to assess the performance of the project in five impact areas - access, community participation, school and regional management, teacher performance, and student learning. It was agreed that the two other key output areas specified in the project framework, namely improved infrastructure and project replication, should not be included in the baseline study; and (ii) present and, where appropriate, describe the baseline information that was collected and analysed in each of these five impact areas
Innovative and rapid antimicrobial susceptibility testing systems
Antimicrobial resistance (AMR) is a major threat to human health worldwide, and the rapid detection and quantification of resistance, combined with antimicrobial stewardship, are key interventions to combat the spread and emergence of AMR. Antimicrobial susceptibility testing (AST) systems are the collective set of diagnostic processes that facilitate the phenotypic and genotypic assessment of AMR and antibiotic susceptibility. Over the past 30 years, only a few high-throughput AST methods have been developed and widely implemented. By contrast, several studies have established proof of principle for various innovative AST methods, including both molecular-based and genome-based methods, which await clinical trials and regulatory review. In this Review, we discuss the current state of AST systems in the broadest technical, translational and implementation-related scope
Development and evaluation of a novel, semiautomated Clostridium difficile typing platform
We describe a novel, semiautomated Clostridium difficile typing platform that is based on PCR-ribotyping in conjunction with a semiautomated molecular typing system. The platform is reproducible with minimal intra- or interassay variability. This method exhibited a discriminatory index of 0.954 and is therefore comparable to more arduous typing systems, such as pulsed-field gel electrophoresis
Editorial: Behind the Making
Few theses, proposals and books in game studies start without some statement of the importance of video games as a media format. However, despite this emphasis on the industry’s size and importance, very little academic attention goes toward what is behind the process of designing games.Game developer Katharine Neil, writing about the state of the game industry and its relation to academia mounts a call to arms: "We can demand research and development into design support technology — not for more tools for prototyping and production or metrics, but for tools that support design thinking".For Neil, these have led to a palpable stagnation in game design. Judging by the articles selected for this issue of Press Start, young game scholars increasingly seek to ameliorate both the lacking academic reflection on game design; and the lack of communication that Neil diagnoses between academics and game makers
Inhibition of intestinal epithelial apoptosis improves survival in a murine model of radiation combined injury
World conditions place large populations at risk from ionizing radiation (IR) from detonation of dirty bombs or nuclear devices. In a subgroup of patients, ionizing radiation exposure would be followed by a secondary infection. The effects of radiation combined injury are potentially more lethal than either insult in isolation. The purpose of this study was to determine mechanisms of mortality and possible therapeutic targets in radiation combined injury. Mice were exposed to IR with 2.5 Gray (Gy) followed four days later by intratracheal methicillin-resistant Staphylococcus aureus (MRSA). While either IR or MRSA alone yielded 100% survival, animals with radiation combined injury had 53% survival (p = 0.01). Compared to IR or MRSA alone, mice with radiation combined injury had increased gut apoptosis, local and systemic bacterial burden, decreased splenic CD4 T cells, CD8 T cells, B cells, NK cells, and dendritic cells, and increased BAL and systemic IL-6 and G-CSF. In contrast, radiation combined injury did not alter lymphocyte apoptosis, pulmonary injury, or intestinal proliferation compared to IR or MRSA alone. In light of the synergistic increase in gut apoptosis following radiation combined injury, transgenic mice that overexpress Bcl-2 in their intestine and wild type mice were subjected to IR followed by MRSA. Bcl-2 mice had decreased gut apoptosis and improved survival compared to WT mice (92% vs. 42%; p<0.01). These data demonstrate that radiation combined injury results in significantly higher mortality than could be predicted based upon either IR or MRSA infection alone, and that preventing gut apoptosis may be a potential therapeutic target
Compartments revealed in food-web structure
Compartments(1) in food webs are subgroups of taxa in which many strong interactions occur within the subgroups and few weak interactions occur between the subgroups(2). Theoretically, compartments increase the stability in networks(1-5), such as food webs. Compartments have been difficult to detect in empirical food webs because of incompatible approaches(6-9) or insufficient methodological rigour(8,10,11). Here we show that a method for detecting compartments from the social networking science(12-14) identified significant compartments in three of five complex, empirical food webs. Detection of compartments was influenced by food web resolution, such as interactions with weights. Because the method identifies compartmental boundaries in which interactions are concentrated, it is compatible with the definition of compartments. The method is rigorous because it maximizes an explicit function, identifies the number of non-overlapping compartments, assigns membership to compartments, and tests the statistical significance of the results(12-14). A graphical presentation(14) reveals systemic relationships and taxa-specific positions as structured by compartments. From this graphic, we explore two scenarios of disturbance to develop a hypothesis for testing how compartmentalized interactions increase stability in food webs(15-17).Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/62960/1/nature02115.pd
Fourth-wave HCI meets the 21st century manifesto:Creative subversion in the 'CHI-verse'
We take up Bødker’s challenge to ‘identify’ a fourth wave HCI, building on the work of Blevis et al. and others to shore up a new vision that places ‘politics and values and ethics’ at the forefront without abandoning the strengths of previous waves. We insist that a fourth wave must push harder, beyond measured criticism for actual (e.g. institutional) change. We present two studies performed at CHI’19, where we used our MANIFESTO! game to: 1) take the temperature of colleagues on adopting an activist stance, 2) test manifesto writing as a key activity in pushing HCI forward into the fourth wave, and 3) test our game for subsequent iterations, and as a probe for inspiring new digital tools. With the enthusiastic response received to gameplay, facilitated in part through a novel method using tableau vivant, we argue for taking political activism from the margins into mainstream HCI
Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial
Background
Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy
