"Mixing business with pleasure?" : Unga medarbetares upplevelser av after work

Hellsten, Lisa, Holmén Larsson, Anna January 2016 (has links)
After work – ett svenskt begrepp på ett populärt fenomen bland dagens arbetsplatser som innebär att medarbetare fortsätter att umgås efter arbetstid över exempelvis en öl. Något som kan leda till att vänskapsrelationer formas och att privatlivet allt mer sipprar in i den professionella världen. Då forskning har påvisat att djupare relationer mellan medarbetare kan få positiva följder för organisationen i sig är detta något som ofta uppmuntras av organisationer. Dock kan det råda en osäkerhet kring vilket förhållningssätt som medarbetarna ska ha till varandra under denna vardagligare umgängesform, där alkohol dessutom är inblandat. Ska de spela rollen som kollega eller som vän? Ovissheten gällande vilken roll man ska inta i en situation leder också till att förväntningarna upplevs som oklara och svåra att leva upp till. Denna studie syftar till att undersöka om unga medarbetare upplever att after work har en betydelse för relationerna på arbetsplatsen. Frågeställningarna som studien utgår från är om after works har någon betydelse för gemenskapen, vilka faktorer som spelar roll vid formandet av relationer på en after work samt hur medarbetare uppfattar gränsen mellan yrkesperson och privatperson i förhållande till after work. Medarbetarnas upplevelser har studerats i relation till Goffmans teori om definitionen av situationen, team, intrycksstyrning samt bakre och främre regioner, Hochschilds emotionsteori om känslohantering och känsloregler samt Nippert-Engs teori om gränsdragningar mellan arbetsliv och privatliv. Tio stycken intervjuer med medarbetare mellan 20-30 år har analyserats utifrån en fenomenologisk ansats. Resultatet har visat att gemenskapen som formas under en after work har en dubbelsidig inverkan på relationerna. Vissa knyter starkare band medan andra kan känna en press att medverka för att inte hamna utanför. Det har uppmärksammats att den privata rollen allt mer inskränker på yrkesrollen, något som visat sig vara positivt då medarbetarna skapar närmare relationer till varandra men även problematiskt då vissa hellre vill hålla isär de olika sociala rollerna. Det har även framkommit att alkoholen är en central faktor vid formandet av relationer under en after work.

Perceptual learning in the spiral aftereffect.

Masland, Richard Harry. January 1965 (has links)
Recent attempts to explain the spiral aftereffect have been based on hypothetical neurological events occurring in cortical area 17. For example, Spitz (1958) has interpreted the effect in terms of gestalt theory's electrochemical fields. [...]

Impact damage and damage tolerance of fibre reinforced advanced composite laminate structures

Lloyd, James C. January 2002 (has links)
The primary objective of this work is to experimentally examine the effect of various geometric parameters on the impact damage and damage tolerance of thin carbon/epoxy plate and panel structures. Due to the number of parameters involved in a low velocity impact event and the complexity of the damage created, determining what effect individual parameters have is extremely demanding, especially when some of the parameters may even be coupled. However, by experimentally simulating in a controlled manner, either the impact event or the damage created, the effect of individual geometric parameters can be isolated and determined. A quasi-static indentation test has been used to simulate an impact event. The parameters of indenter size, nose shape, plate size and boundary condition, were examined. Four different plate failure modes were identified. Indenter nose shape was found to be the dominant geometric parameter, as a change in nose shape resulted in a change in failure mode and hence maximum load. From this work, a set of geometric parameters was selected for impact testing. Impact testing at various Incident Kinetic Energies (IKE) was performed on an instrumented drop weight impact rig. From examination of internal and external damage, the development of damage to increasing IKE was determined and shown to have four distinctive phases. Coupled with strike and rebound velocity measurementsa, non-linear relationship between IKE-damage area was established and a delamination threshold energy level of 1.1 J was calculated. Damaget olerance assessmenot f impacted panels was then performed in a Compression-After- Impact (CAI) rig. Strain gauge responses allowed global and local behaviour to be compared to intact specimens. It was found that once a critical damage size was surpassed, a gradual nonlinear degradation in compressive strength was observed until a point was reached where no further degradation in performance was attained. Furthermore, propagation of internal damage in a stable and unstable manner was directly linked to the nature of sublaminate buckling behaviour. Damaget olerance assessmenot f artificially delaminatedp anels loaded in compressionw as then performed. A single artificial delamination of various size, shape and orientation, embedded at the centre of a panel was examined. Delamination width was found to be the dominant geometric parameter. Hence, when comparing a circular delamination to an elliptical one of the same area, the effect of orientation and shape is aspect ratio dependent. Finally, a comparison of impacted and artificially delaminated panels was made.
