Alpine skis have changed dramatically in the last century. Long and straight wood skis have evolved into shorter lengths and now contain a plethora of modern materials. Shaped skis have become the norm. Today’s skis also offer a variety of waist widths and shapes to cater to specific uses. By studying how skis have evolved, it is possible to gain insight into how the design of alpine skis has progressed. To do so, the mechanical properties of 1016 skis, from the 1920s to 2019, were measured with a machine developed at the University of Sherbrooke. The resulting data are used to calculate various geometric, stiffness and performance parameters. The evolution of these parameters over the years is analyzed. This analysis provides a better understanding of the evolution of ski design and shows when the introduction of new materials and shaping concepts has changed the way skis are designed.

And Performance

Competitive ski mountaineering (SKIMO) has achieved great popularity within the past years. However, knowledge about the predictors of performance and physiological response to SKIMO racing is limited. Therefore, 21 male SKIMO athletes split into two performance groups (elite: VO2max 71.2 ± 6.8 ml· min-1· kg-1 vs. sub-elite: 62.5 ± 4.7 ml· min-1· kg-1) were tested and analysed during a vertical SKIMO race simulation (523 m elevation gain) and in a laboratory SKIMO specific ramp test. In both cases, oxygen consumption (VO2), heart rate (HR), blood lactate and cycle characteristics were measured. During the race simulation, the elite athletes were approximately 5 min faster compared with the sub-elite (27:15 ± 1:16 min; 32:31 ± 2:13 min; p < 0.001). VO2 was higher for elite athletes during the race simulation (p = 0.046) and in the laboratory test at ventilatory threshold 2 (p = 0.005) and at maximum VO2 (p = 0.003). Laboratory maximum power output is displayed as treadmill speed and was higher for elite than sub-elite athletes (7.4 ± 0.3 km h-1; 6.6 ± 0.3 km h-1; p < 0.001). Lactate values were higher in the laboratory maximum ramp test than in the race simulation (p < 0.001). Pearson’s correlation coefficient between race time and performance parameters was highest for velocity and VO2 related parameters during the laboratory test (r > 0.6). Elite athletes showed their superiority in the race simulation as well as during the maximum ramp test. While HR analysis revealed a similar strain to both cohorts in both tests, the superiority can be explainable by higher VO2 and power output. To further push the performance of SKIMO athletes, the development of named factors like power output at maximum and ventilatory threshold 2 seems crucial.

This collection brings together six papers of the some seventy that were presented at the international symposium held at Université Laval in October, 1987 entitled “Mémoires, Histoires, Identités”. Organized jointly by the History Department of Université Laval, the Ecole des Hautes études en sciences sociales de Paris and the Laboratoire 363 “Tiers-Monde-Afrique” CNRS/Université Paris VII, the symposium aimed to stimulate reflection and research on the links between the construction of identities and the production of history as a discourse on the past, and thus on the links maintained by two modes of production of History-the academic and the popular. Achieving this objective required a broadening of the empirical field to avoid unduly singularizing African experiences.The papers here concentrate on the process of the production of history by historical actors or by cultural intermediaries who, educated or not, are not of the university milieu which imposes the western conception of historical discourse. The relationships between academic and popular discourse and between the norms of the dominant culture and the practices of dominated cultures are at the center of the analyses.Isaiah Berlin recently summarized the past century as follows:The other, without doubt, consists in the great ideological storms that have altered the lives of virtually all mankind: the Russian Revolution and its aftermath – totalitarian tyrannies of both right and left and the explosions of nationalism, racism, and, in places, of religious bigotry, which, interestingly enough, not one among the most perceptive social thinkers of the nineteenth century had ever predicted.

Insight Into

Over the past decade, universities have invested heavily in startup accelerator programs; however, their role in the university entrepreneurial ecosystem is ambiguous. Are university startup accelerators intended to educate or are they created to facilitate business starts and to contribute to regional economic development? In contrast, most private-sector startup accelerators serve a consistent and differentiated role in the entrepreneurial ecosystem—they provide programming and resources to startups to increase the probability of a return on investment. Understanding the role of university startup accelerators is an important precursor to evaluating their impact and whether or not the return is worth the considerable investment. In this study, we poll university accelerator directors to gain their perspective on the role(s) that university startup accelerators play and to identify how they are structured and operated. Our research reveals a fairly uniform structure and mode of operation. While facilitating business starts is a key role for some, it confirms education as the primary role for university startup accelerators. We outline appropriate means of assessing the learning that takes place in accelerator programs, offer insight into how these findings can help accelerator directors deliver on outcomes and demonstrate impact, and propose avenues for future research.

A Share

It is always agreeable to offer congratulations to someone who is celebrating a jubilee. It is a particular pleasure to do so when the ‘child’ whose birthday it is can look back over 150 years of existence, and all those who have a share in the jubilee may reflect that the thanks for the achievements of the past and wishes for the future serve the cause of publicity. For no one who sets out to discuss the state of classical studies in Germany can, or should, fail to mention the Leipzig publishing firm of B. G. Teubner. Here publishing and scholarship have in the past century and a half formed an indissoluble partnership which has made it its duty to provide the best texts for use in the study of classical antiquity.

On August 20, 1933, there passed away at the age of 77 one of the older Fellows of the Chemical Society, and yet another of the Oxford University staff of the Odling regime, in the person of Dr. Victor Herbert Veley, F.R.S. Those who worked in the University laboratories in the last decades of the past century and the first few years of the present will recollect with a sigh of affection the well-known spare figure with the humorous twinkle of the eye, and the clothes well stained with nitric acid ; and those Fellows in the habit of attending scientific meetings in London in the first decade of the present century will perhaps associate his presence with a certain unwonted liveliness .

Insight Into

In teaching Mikrokosmos to some four score children over a period of several years, I have realized that it serves numerous musical purposes beyond just that of being another series of pieces and studies for pupils. In addition to laying a strong and richly varied foundation for the understanding and performance of twentieth-century music, it presents almost unending varieties of situations for facilitating sight-reading and transposition. The work offers virtually every pianistic and musical problem to the student, and interestingly enough, its use gives him increased insight into music of the past as well as of the present.

Traditional Performance

In 1923 a paper was written to describe the traditional Hopi ceremonial ways. The phrase “hybridity in transition” was a descriptor of their process. This was a time when many aspects of Indigenous traditions including language, were illegal or prohibited in many ways. This paper and performance explores the evolution of pseudo-traditional performance practices over the past century. How can a culture maintain its core-values and essence, explicitly or embedded within new forms of presenting and representing its identity and authentic voice? Using empirical evidence, we journey through the transition from an art form a child participates in, the lifelong dancer, and to the artist-educator in order to justify creative modifications to traditions. How can cultural traditions be maintained and celebrated during times of suppression? How and why is tradition important to each generation as it faces major social influences? What is the value and power of collaborative work between tradition and modernity? How can an Indigenous culture explore, decolonize and empower its future thorough performance?

A breadth of literature has examined how gig workers use online forums. The past literature focuses primarily on how gig workers for mainstream corporate platforms leverage forums. Yet, marginalization, stigma, censorship, and criminalization all shape how people, including gig workers, use digital technology. In this work, we seek to take a first step toward understanding how marginalized, stigmatized, digitally censored, and in some cases criminalized gig workers leverage the affordances of online public forums to build community and increase their welfare. To do so, we conduct a qualitative analysis of 4,000 posts and 25,851 comments shared over four months in a large online public forum used by sex workers for peer support. Sex workers sit at the intersection of multiple marginalized communities, and thus offer a lens into the broader use of forums by marginalized labor communities. Our findings offer insight into how these workers use moderation to preserve their safety and community. Further, we highlight similarities and differences between how this community utilizes the forum platform and prior scholarship on the use of online forums by gig workers.

Insight Into

Banyuwangi is a highly unique and dyamic locality. Situated in between several ‘giants’ traditionally known as centres of culture and tourism, that is, Bali to the east, larger Java to the west, Borneo to the north, and Alas Purwo forest to the south, Banyuwangi is a hub for culture and metaphysical attention, but has, over the past few decades, become a focus of poltical disourse, in Indonesia. Its cultural and spiritual practices are renowned throughout both Indonesia and Southeast Asia, yet Banyuwangi seems quite content to conceal many of its cosmological practices, its spirituality and connected cultural and language dynamics. Here, a binary constructed by the national government between institutionalized religions (Hinduism, Islam and at times Chritianity) and the liminalized Animism, Kejawen, Ruwatan and the occult, supposedly leading to ‘witch hunts,’ have increased the cultural significance of Banyuwangi. Yet, the construction of this binary has intensifed the Osing community’s affiliation to religious spiritualistic heritage, ultimately encouraging the Osing community to stylize its religious and cultural symbolisms as an extensive set of sequenced annual rituals. The Osing community has spawned a culture of spirituality and religion, which in Geertz’s terms, is highly syncretic, thus reflexively complexifying the symbolisms of the community, and which continue to propagate their religion and heritage, be in internally. These practices materialize through a complex sequence of (approximately) twelve annual festivals, comprising performance and language in the form of dance, food, mantra, prayer, and song. The study employs a theory of frames (see work by Bateson, Goffman) to locate language and visual symbolisms, and to determine how these symbolisms function in context. This study and presentation draw on a several yaer ethnography of Banyuwangi, to provide an insight into the cultural and lingusitic symbolisms of the Osing people in Banyuwangi. The study first documets these sequenced rituals, to develop a map of the symbolic underpinnings of these annually sequenced highly performative rituals. Employing a symbolic interpretive framework, and including discourse analysis of both language and performance, the study utlimately presents that the Osing community continuously, that is, annually, reinvigorates its comples clustering of religious andn cultural symbols, which are layered and are in flux with overlapping narratives, such as heritage, the national poltical and the transnational.

Insight Into

In a volume of miscellaneous manuscripts at the British Museum, placed at random and inconspicuously among larger folio leaves, is a set of notes headed “Sterne.” The notes were written by Joseph Hunter, the nineteenth-century antiquary and literary historian, and they came to the British Museum with Hunter's other papers shortly after his death in 1861. In view of the abundant information about Sterne's private life which the notes contain, it is surprising that this item has remained unindexed and that it is not mentioned in the catalogue description of the volume. In the absence of such references, very likely only an occasional reader who has happened upon them has seen these notes, and, since the major biographies of Laurence Sterne make no use of distinct details which Hunter provides, it is quite possible that none of Sterne's biographers have encountered Hunter's information during the past century. At present, our familiarity with the early years of Sterne's marriage and his residence at Sutton-on-the-Forest is rather limited, based as it is upon isolated public records, some letters, fugitive anecdotes, and the unflattering and sometimes vicious account written by John Croft. No impartial memoirs with any claim to authenticity or wealth of details have until now seemed available. Thus, the intimate account of Sterne which Hunter has given presents to modern scholars an unexpected and promising opportunity to gain new insight into the life and, perhaps, into the work of one of England's most unusual writers. A transcript of Hunter's notes appears below, followed by a brief evaluation of them according to our present knowledge of Laurence Sterne.
