Following the technical demonstration of the Mars Helicopter on the Mars 2020 mission, interest in further exploration of Mars utilizing rotorcraft is expected to increase. Previously, scientific exploration has been limited by the resolution of instruments on satellites and the terrain a rover can traverse. Rotorcraft enable exploration in previously inaccessible locations with increased efficiency compared to rovers and improved resolution (compared to satellites). This paper describes missions designed to utilize the unique capabilities of rotorcraft in order to advance the science performed extraterrestrially. For Mars this includes tasks such as determining if Mars ever supported life, understanding climate processes and history, determining the evolution of Martian geology, and preparing for human exploration. The missions fall into three general categories: rover assistance, sample collection, and data collection. Complimentary conceptvehicles are also discussed. This paper is meant to serve as a reference, resource, and starting point for the future exploration of Mars with rotorcraft.

Friedrich Nietzsche's influence on Isadora Duncan's work, in particular his idea of the Dionysian, has been widely discussed, especially in regard to her later work. What has been left underdeveloped in critical examinations of her work, however, is his influence on her earlier choreographic work, which she defended in a famous speech held in 1903 called The Dance of the Future. While commentators often describe this speech as ‘Nietzschean’, Duncan's autobiography suggests that she only studied Nietzsche's work after this speech. I take this incongruity as a starting point to explore the connections between her speech and Nietzsche's work, in particular his Thus Spoke Zarathustra. I argue that in subject and language Duncan's speech resembles Nietzsche's in important ways. This article will draw attention to the ways in which Duncan takes her cues from Nietzsche in bringing together seemingly conflicting ideas of religion and an overturning of morality; Nietzsche's notion of eternal recurrence and the teleology present in his idea of the Übermensch; and a renegotiation of the body's relation to the mind. In doing so, this article contributes not only to scholarship on Duncan's early work but also to discussions of Nietzsche's reception in the early twentieth century. Moreover, the importance Duncan ascribes to the body in dance and expression also asks for a new understanding of Nietzsche's own way of expressing his philosophy.

This article encourages a move away from the excessively inward gaze of ‘to thine own self be true’ and explores ‘I AM’ consciousness as a starting point. An I AM approach encourages a move from the measurable self to the immeasurable expansiveness and mystery of our own becoming. It is to step beyond the lines drawn around the ‘true self’ or the lines that others would have us draw. I AM consciousness reflects an ancient Indigenous thread that echoes through millennia and reminds humans that we are a movement through time, and each person is a present link to the past and the future, woven into a fabric of belonging.

Incidence of ischemic stroke and transient ischemic attack in young adults is rising. However, etiology remains unknown in 30–40% of these patients when current classification systems designed for the elderly are used. Our aim was to identify risk factors according to a pediatric approach, which might lead to both better identification of risk factors and provide a stepping stone for the understanding of disease mechanism, particularly in patients currently classified as “unknown etiology”. Risk factors of 656 young stroke patients (aged 18–50) of the FUTURE study were categorized according to the “International Pediatric Stroke Study” (IPSS), with stratification on gender, age and stroke of “unknown etiology”. Categorization of risk factors into ≥1 IPSS category was possible in 94% of young stroke patients. Chronic systemic conditions were more present in patients aged <35 compared to patients ≥35 (32.6% vs. 15.6%, p < 0.05). Among 226 patients classified as “stroke of unknown etiology” using TOAST, we found risk factors in 199 patients (88%) with the IPSS approach. We identified multiple risk factors linked to other mechanisms of stroke in the young than in the elderly . This can be a valuable starting point to develop an etiologic classification system specifically designed for young stroke patients.

Peritoneal dialysis-related infections are important morbidity/mortality causes, being staphylococci the most prevalent agents. SinceStaphylococcus aureusnasopharynx carriage is a known risk factor for PD infections and the oral cavity is a starting point for systemic diseases development, we aimed at comparing the oral staphylococci colonization between PD patients and controls and studying the association with PD-related infections. Saliva samples were plated in Mannitol salt, and isolates were identified byDnaJgene sequencing. Staphylococci PD-related infections were recorded throughout the 4-year period following sample collection.Staphylococcuscolonization was present in >90% of the samples from both groups (a total of nine species identified). PD patients presented less diversity and less prevalence of multispeciesStaphylococcuscolonization. Although all patients presentingStaphylococcus epidermidisPD-related infections were also colonized in the oral cavity by the same agent,only 1 out of 7 patients with ESI caused byS.aureuspresentedS. aureusoral colonization. Staphylococci are highly prevalent in the oral cavity of both groups, although PD patients presented less species diversity. The association between oralStaphylococcuscarriage and PD-related infections was present forS. epidermidisbut was almost inexistent forS. aureus, so, further studies are still necessary to evaluate the infectious potential of oralStaphylococcuscarriage in PD.

Three techniques for assessing extension of one's personal future (line-marking, open-ended report, life-events) were compared in a sample of 74 respondents. Two points of data collection were employed to examine short-term stability. At both administrations, correlations among indices suggested that techniques were only moderately comparable. Short-term stabilities were variable; correlations ranged from .42 to .79. Across subgroups of the sample, the direct, open-ended report of extension showed the greatest stability, while life-event extension showed the least. Apparently, extension of thinking about the future should be assessed by more than one technique to investigate potential relationships with other variables or changes over time in perspective about the future.

Tony Davies and a number of others consider collecting supplementary spectroscopic data. Like Eurospec, the plan is to use such supplementary data not only to enhance the published paper, but also to aid thorough peer-review by allowing reviewers access to the full data rather than, as Tony puts it, “low-resolution images of data”. I’m sure you will be interested in a look at the future through this column.

Slampt Underground Organisation was conceived in 1992 by Rachel Holborow and Pete Dale, issuing music, fanzines and ephemera from then until 2000. Perceived as a record label, Slampt sold tens of thousands of units and seems to have had a significant impact on particular individuals who might or might not be best described as ‘fans’. This article uses the author’s archives and reflections to collate detail, much of it not publically available before, about a label/distributor/organization, which has already been a point of interest to several researchers and journalists but which is nonetheless unknown to most, even in punk-related music scenes, in the present century. The author, as one half of Slampt’s de facto leading partnership, reveals that this status as a largely forgotten arm of 1990s UK punk is not entirely accidental: Dale and Holborow actively believed in ephemerality as an ideal, particularly in punk. Using this case as a starting point, the article asks whether punk really ought to be as fixated on documenting its past, finding its place in museums/galleries and gaining recognition in rock history. Is punk about collectible objects, about a particular mode of subjectivity or, perhaps, about a phenomenological combination of the two? The irony of the author writing the article at this time is acknowledged: Slampt is being written back in to punk history, even if only in the margins, through the act of publishing this piece. Nonetheless, the article is based around the assumption that the present and the future will always be more important than the past.

Over the years, as people's lives have improved, our need for transportation and accommodation has increased, driving the rapid growth of the sharing economy. Some well-known network sharing platforms, such as Uber, Drip and Airbnb, provide a large number of convenient options for users with transactional needs, make more use of idle tourism, accommodation and other resources. Sharing economy platforms continue to improve the content and format of their products, but at the same time, the future of sharing platforms and the difficulty of competition is a concern as more platform companies become involved and prices become more transparent. Under this circumstance, optimizing product pricing has become an urgent need for many sharing economy platforms. In this paper, we take Airbnb as the starting point and conduct an empirical analysis of the blocking behavior of homeowners based on proprietary data to explore the factors that affect their product supply. We find that price, number of beds, and listing type all have a significant impact on blocking houses. After that, we conducted further research on price factors and developed a model aiming at profit maximization to obtain the best pricing range for the region and provide suggestions for pricing strategies. Keywords: Sharing Economy, Blocking behavior, Pricing Strategy, Airbnb
