Māori Mārx: Some Provisional Materials

This article gathers together some provisional materials for the construction of a Māori Mārx. I begin by following Marx’s thought as he continually complexifies his understanding of the determinants of history in his search for the proper starting place for a materialist dialectics. I leave historical Marx at the close of his life, occupied with the passionate study of Indigenous modes of life. Returning his gaze, I read Marx from an Indigenous perspective, sketching some of the lineaments of a Māori Mārx for whom whakapapa is the central concept. From this perspective, I describe an Indigenous, comparative, and historical materialism, termed ‘geometry of life’, that seeks the consistency between modes of life and the modes of thinking that emanate within them. I close by suggesting that we must conceive of ourselves as part of the ensemble powers of a proletarian Papatūānuku if we are to conserve the earth and abolish capital

The New Opportunity to Lead: A Vision for Education in Massachusetts in the Next 20 Years

This report is based on the vision that the Massachusetts Business Alliance for Education (MBAE) advocates for the Commonwealth of Massachusetts. In preparing this report, the MBAE asked us explicitly what it would take for Massachusetts to have the best-performing system in the world in within 20 years. In the field of public education, Massachusetts has often - sometimes spectacularly - led before. By creating the best education in the World, it would undoubtedly do so again and provide better opportunities for all its citizens

Using PROMs to guide patients and practitioners through the head and neck cancer journey

Simon N Rogers,1,2 Brittany Barber3 1Evidence-Based Practice Research Centre (EPRC), Faculty of Health and Social Care, Edge Hill University, Ormskirk, UK; 2Regional Maxillofacial Unit, University Hospital Aintree, Liverpool, UK; 3Head and Neck Department, Icahn School of Medicine at Mount Sinai (MSSM), New York, NY, USA Abstract: The measurement of patient-reported outcome measures (PROMs) following head and neck cancer (HNC) has the capacity to substantially enhance the care of patients and their care-givers following the diagnosis and treatment of HNC. Literature concerning PROMs has increased exponentially in the past 2 decades, producing a vast array of data upon which the multidisciplinary team can reflect. For this review, “Handle On QOL” has been used as a source of references to illustrate the points raised. PROMs are contextualized by considering the clinically-distinct key stages that cancer patients endure: diagnosis, treatment, acute toxicity, early recovery, late effects, recurrence, and palliation. The PROMs are considered in six main categories: 1) those addressing cornucopia of issues not specific to cancer; 2) those addressing issues common to all cancers; 3) questionnaires with items specific to HNC; 4) questionnaires that focus on a particular aspect of head and neck function; 5) those measuring psychological concerns, such as depression, anxiety, or self-esteem; and 6) item prompt lists. Potential benefits of PROMs in clinical practice are discussed, as are barriers to use. The way forward in integrating PROMs into routine HNC care is discussed with an emphasis on information technology. Keywords: patient reported outcomes, head and neck cancer, quality of life, multi-professiona

Ptolemy: An instrument aboard the Rosetta lander Philae, to unlock the secrets of the solar system

Ptolemy is a miniature chemical analysis suite currently on board the ESA Rosetta comet lander Philae. This poster describes the operation of the instrument, and presents data generated thus far during a comprehensive ground testing programme

Effects of rarefaction on cavity flow in the slip regime

The Navier-Stokes-Fourier equations, with boundary conditions that account for the effects of velocity-slip and temperature-jump, are compared to the direct simulation Monte Carlo method for the case of a lid-driven micro-cavity. Results are presented for Knudsen numbers within the slip-flow regime where the onset of nonequilibrium effects are usually observed. Good agreement is found in predicting the general features of the velocity field and the recirculating flow. However, although the steady-state pressure distributions along the walls of the driven cavity are generally in good agreement with the Monte Carlo data, there is some indication that the results are starting to show noticeable differences, particularly at the separation and reattachment points. The modified Navier-Stokes-Fourier equations consistently overpredict the maximum and minimum pressure values throughout the slip regime. This highlights the need for alternative boundary formulations or modeling techniques that can provide accurate and computationally economic solutions over a wider range of Knudsen numbers

Micro-scale cavities in the slip - and transition - flow regimes

Differences between Navier-Stokes-Fourier (NSF) slip/jump solutions and direct simulation Monte-Carlo (DSMC) computations are highlighted for a micro lid-driven cavity problem. The results indicate a need for better modelling techniques which at the same time retain low computational cost of NSF models. We also highlight the fact thatmany micro-flows that have been considered are simple planar flows and typical classification systems are defined on such flows. We show that for complex flows, such as thedriven cavity, non-equilibrium effects are more appreciable and their onset occurs at lower Knudsen numbers than expected

Applied Studies of Raptor Sensory Ecology are Rare

Light and noise often act as pollutants, but can also be used as tools for managing wildlife (e.g., sensory deterrents). Given that raptors are among the most threatened groups of birds, we expected there to be a moderate amount of applied research on their sensory ecology. We searched Web of Science and Google Scholar to quantify and classify the research that has been conducted on the applied sensory ecology of raptors. Of 32 studies assessing the effects of sensory pollution on raptors, we found that 10 studies examined effects of light pollution and 24 studies examined effects of noise pollution. Most of the studies regarding sensory pollution were of owls (21 studies). The United States was the site of the most noise pollution studies (seven studies) whereas Spain and Poland (two studies each) were sites of the most studies of light pollution. We found only seven studies that directly collected data regarding sensory deterrents. With so few studies examining applied aspects of the sensory ecology of raptors, we argue that effects of sensory pollution are poorly understood and the efficacy of sensory deterrents is largely unknown. Light and noise pollution are spreading across much of the globe. Applied research on the sensory ecology of raptors must be made a priority if wildlife managers are to conserve this imperiled group of birds

Gas containment for in situ sample analysis on the Moon: Utility of sealing materials in the presence of dust

Lunar dust presents a serious challenge to all operations on the Moon, whether human or robotic. It can be especially problematic in applications where it is necessary to make high integrity, gas-tight seals, such as within payloads designed for in situ analysis of lunar ices and volatiles. The challenge has been addressed within the context of the ProSPA instrument being developed for the Luna-27 mission. Soft sealing materials are preferred in order to minimise the required sealing force to enable use of lightweight actuators. JSC-1A simulant was used to test and compare the sealing performance of the elastomer Kalrez® 7075 and of Indium. It was found that both materials were able to seal at dust levels of up to 0.90 mg/cm2 with an applied force of up to 400 N. Indium offers the best sealing performance (better than 10-7 mbar.l.s-1) but Kalrez® is capable of operation at higher temperature, which may be beneficial in applications in which samples are heated to release gases for analysis
