Sammanfattning Syfte Syftet med studien är att undersöka hur studenter i Stockholm transporterar sig till och frånhögskola/universitet samt se deras förändringsbenägenhet att gå från inaktiv transport till aktivtransport. Frågeställning – Hur tar sig studenterna till sin högskola/universitet? – Vad påverkar deras val av transportmedel? – Vad kan få dem att välja ett aktivt transportmedel? Metod En kvantitativ studie genomfördes där datainsamlingsmetoden var en webenkätundersökning viaprogrammet Defgo. Ett riktat urval skedde på målgruppspopulationen där samtliga rektorer förhögskolor samt universitet inom Stockholm stad tillhörande portalen ”Studera i Stockholm”tillfrågades via mail om deltagande, totalt nitton av tjugoen högskolor är anslutna till portalen. Urvalsgruppen kom att bestå av 541 respondenter på enkäten från tolv högskolor av totalt tjugoeninom Stockholm stad. Enkäten utformades utifrån tidigare enkäter inom samma område som grund. En pilotstudie genomfördes i gratisprogrammet SurveyMonkey för att sedan distribuera denslutgiltig version av enkäten via programmet Defgo. Enkäten i sin helhet bestod av 21 frågor medöppna samt givna svarsalternativ. Resultatbearbetningen utfördes i samma program, Defgo. Diagram utformades i Excel. Resultat Hela 32 % använder sig av lokaltrafiken för att ta sig till sin högskola/universitet, 34 % använderlokaltrafiken i kombination med promenad, 5 % använder lokaltrafiken i kombination med cykel, 11 % promenerar samt 9 % tar cykeln. Knappt 4 % tar bilen och ingen åker taxi. Lite mer än 3 % tarsig på annat sätt till universitet/högskolan så som lokaltrafik i kombination medskateboard/longboard eller på inlines. Ungefär 70 % väljer det tidseffektivaste ressättet, 41 % väljertransportmedlet utifrån bekvämlighet, medan cirka 30 % väljer det billigaste transportmedlet. 32 % skulle välja annat transportmedel om det innebar en vinst i tid, tidseffektivare transport. 18 % uppgav ett billigare alternativ skulle få respondenterna att byta transportmedel. 74 % uppgav att omderas krav uppfylldes för ett annat transportmedel så var de villiga att byta. 15 % var ej villiga attbyta transportmedel. På frågan om respondenterna kan tänka sig att gå eller cykla, alternativt ikombination med lokaltrafiken, till högskolan/universitetet svarade cirka 70% att de kan tänka sigdet, 6 % svarade nej, medan 11 % svarade kanske. Slutsats De flesta studenter använder sig av lokaltrafiken för transport till högskola/universitet. Valet avtransport för studenter vid högskola/universitet i Stockholm stad pekar således mot att det somavgör valet av transportmedel är sträckan, tidsåtgång och ekonomin. Förändringsbenägenheten ärstor bland de tillfrågade, att gå från inaktiv till aktiv transport. Förslag ges på implementering avprogram omfattande aktiv transport vid olika högskolor, samt förslag på utbildning om aktivtransport, för att få fler studenter delaktiga och mer fysiskt aktiva. Program av dessa slag kan varaav betydelse för att få fler studenter att promenera eller cykla till sina studier. / <p>Kurs: Idrott III</p>

A practical method of reducing aerosolized pathogens and environmental contaminants during commercial transportation could prove beneficial to the health and value of cattle. Having previously determined that there was very limited airflow within moving livestock trailers, an experimental treatment that increased cross-ventilation within commercial cattle trailers by installing aluminum scoops to punch-hole trailers was evaluated. Environmental factors including temperature, ammonia and carbon dioxide concentrations, and percent dry matter of excreted urine and fecal matter were evaluated, along with physiological factors, including complete blood count, serum electrolyte concentrations, percent weight loss, the presence of Salmonella, Escherichia coli, or Mannheimia haemolytica, and 30 day health data. The experiment consisted of two trials, each with two truckloads of 80 cattle each, for a total of 320 cattle. Temperature was evaluated in the center compartments of each trailer at five minute intervals throughout both trips. Ammonia concentrations were measured using passive dosimeters. Jugular blood samples, fecal grab samples, swabs of the terminal rectum and nasal swabs were obtained 8.5 to 10 hours post-transport from 20 cattle from each trailer. Increased ventilation resulted in lower temperatures and ammonia concentrations on both trips. Percent dry matter of excreted urine and fecal matter were inconclusive. There were no treatment effects for complete blood counts or electrolyte and basic chemistry panels, possibly because the cattle had access to both hay and water between transport and sampling, which allowed for recovery. Cattle in the ventilated trailer had an average weight loss of 4.7%, compared with 5.75% for the cattle in the control trailers. Sampling for E. coli O157:H7, Salmonella, and M. haemolytica showed very few positives, likely due to the good condition of the cattle prior to transport. During the 30 days post-transport, no cattle from either treatment required veterinary attention related to transport. The results indicate that increasing ventilation through the use of external air scoops has the potential to improve the health and well-being of cattle during transport.

The aim of this study was to determine the effects of density and provision of water on behavior, stress, and weight loss in slaughter horses during transport. A 16.2-m long, single deck, semi-trailer was divided into three compartments to create high, medium, and low density (5000, 4000, and 3000 kg per compartment, respectively) groups of slaughter horses. A total of six shipments containing 23 to 30 horses per shipment were transported in June and July of 2004 for 18 to 20 h. Horses were a variety of different breeds, ages, sexes, and body conditions, but were typical of slaughter horses. Jugular blood samples were taken from five horses in each of the three density treatments immediately before loading and after unloading at the completion of each shipment. All horses were weighed at the same time as the blood samples were collected. While the truck was stopped, horses in each of two compartments received water from three automatic water bowls in each side of a compartment. The water was provided for 1-h after 8 h of transport and then again just prior to unloading. The third, non-watered compartment served as a control for each of the 1-h watering sessions. Densities selected to receive water were alternated between shipments. The aggressive behavior of the horses for the six shipments was recorded using 12 video cameras installed in the trailer. All occurrences of aggressive behavior were counted from 15-min segments of video during 2-h intervals for each horse that was visible in each density group. Density did not significantly affect (P > 0.21) aggressive behavior, cortisol, serum chemistry profile, dehydration, and weight loss. Aggression level did not differ (P = 0.49) between the first and second halves of the shipments. Individual horses, rather than density, appeared to be the cause of aggressive behavior. The watered and non-watered groups did not differ (P > 0.54) in terms of aggression, cortisol, serum chemistry profile, dehydration, and weight loss. Density and provision of water did not significantly influence aggressive behavior, stress and weight loss in shipments of 18 to 20 h long during warm weather.
