Izvoditi kratke, paralelne zavoje na rolama čini se istim redoslijedom gibanja tijela kao i tijekom izvođenja zavoja na skijama. Stoga rolanje često koriste natjecatelji u alpskome skijanju kao ...zamjenski sport u pripremnom periodu treninga. Većina natjecatelja u alpskome skijanju prvo nauči osnove upravljanja skijama u zavoju, a zatim koriste role kao alternativni sport. S aspekta skijaških početnika koji žele naučiti osnove alpskoga skijanja važno je utvrditi razliku u distribuciji sile pritiska stopala tijekom izvođenja kratkih, paralelnih zavoja na rolama i skijama.
U istraživanju je sudjelovalo pet ispitanica, alpskih skijašica s usvojenom visokom razinom skijaškog znanja koje su na unaprijed definiranim koridorima izvodile kratke, paralelne zavoje na skijama i na rolama. Tijekom izvođenja zavoja na skijama i na rolama ispitanice su koristile Novel uloške za mjerenje sile pritiska. Pomoću njih objektivno je moguće utvrditi razliku između sile i njene distribucije u pojedinim dijelovima lijevog i desnog stopala tijekom skijanja i rolanja. Ukupno je analizirano 70 zavoja tijekom skijanja i 70 tijekom rolanja.
Izmjerena sila na vanjskom stopalu tijekom lijevog zavoja kod izvođenja zavoja na rolama značajno je manja u odnosu na zavoj izveden na skijama (584,82 N vs 764,79 N), a isti je obrazac utvrđen i na vanjskoj nozi u desnom zavoju (564,44 N vs 811,37 N). Značajno veća sila pritiska unutarnje noge u odnosu na vanjsku nogu izmjerena je tijekom rolanja u odnosu na skijanje u oba zavoja (lijevi zavoj-720,26 N vs 378,45 N; desni zavoj-745,23 N vs 412,83 N). Isto tako, rezultati istraživanja pokazuju kako do značajnije sile pritiska unutarnjeg stopala na podlogu tijekom rolanja dolazi vremenski nešto kasnije u odnosu na vanjsko stopalo. Nadalje, tijekom skijanja na medijalnom dijelu stopala vanjske noge, izmjerena prosječna sila je značajno veća u odnosu na zavoj učinjen na rolama (lijevi
zavoj-53,54 N vs 159,64 N; desni zavoj-65,33 N vs 161,33 N).
Utvrđene značajne razlike u distribuciji sili pritiska na podlogu između zavoja izvedenih na rolama i skijama vjerojatno proizlaze iz različitosti u vrsti i nagibu terena, sile trenja koja se javlja između tla te kotača rola i snježne površine i skija, što u konačnici utječe na brzinu kretanja. Iako se zavoji na rolama i skijama izvode s različitom
opremom te na terenima različitih nagiba i vrsta podloge pa time stvaraju različite vrste trenja i u konačnici brzinu kretanja, znanje rolanja može pomoći u učenju alpskoga skijanja.
The rise of naturalism in the Netherlands and Flanders was accompanied by a growing interest in a motif that had drawn attention to itself on several occasions in earlier literary epochs: fate or ...fatum. At least up to the mid-20th century, this motif went on playing an important role in Dutch-language literature. It is striking in this connection that two different notions of fatum are to be found there. On the one hand, an ‘external’ fate is identified – thought of as a supernatural, metaphysical power which determines the course of events in advance. On the other hand, though, an ‘internal’ fate is postulated – a conglomerate of psychological dispositions and hereditary character traits that determine a person’s behaviour. In literary texts, it is not always easy to see whether an ‘external’ or an ‘internal’ idea of fatum is predominant. The present article investigates where the reasons for this ambivalence lie. A thematological procedure was chosen for the purpose, with Deirdre en de zonen van Usnach (1920) by Adriaan Roland Holst serving as a reference point – a novel in which the author made an explicit decision in favour of an ‘external’ idea of fate. Furthermore, two other novels are analysed: Noodlot (1890) by Louis Couperus and De waterman (1933) by Arthur van Schendel.

To celebrate the 80th birthday of poet Henriëtte Roland-Holst, money was collected for a gift. At her request, this money was used to purchase a country house for the care of abused city youth and ...other children in poor circumstances. The purchased house, on the estate "De Haere"(?) near Doornspijk, the so-called Henriette Roland-Holst Oord is opened in honor of Mrs. Roland-Holst. SHOTS: - Roland-Holst, assisted by two ladies, comes running through the forest; - ext. house; a number of adults and children have gathered in front of it; - Roland-Holst sits on a chair and listens to a speech by the mayor; - a girl plants a Maypole; Roland-Holst helps.
