The purpose of this paper is to give the reader an insight into the graphical interface of a Learning Management system, the theme, how it functions and its importance. The main point is how the creation of new themes can be done, and two different approaches are examined and compared.The use of learning management systems have been growing rapidly over the past years. Modern learning, be it basic school, higher education or professional training, is almost always supported by some learning management system where both instructors and participators share learning material, assignments, discussion, among other things.The theme of a learning management system is of great importance and can have a substantial impact on the efficiency of the actual learning process. Themes might also differ in their purpose, thus depending on the target audience, creating a specific theme might be desirable.The work done in this paper examines the structure and function of themes in the web based Totara learning management system, and looks at two different approaches to creating new themes. These approaches involve creating something from scratch, and cloning an already existing theme.The conclusion drawn from the work done in this paper is that the most efficient way of creating a new theme, is through cloning an already existing theme. Only when time and experience is plentiful, and a full control over the theme structure is desirable, is creating a theme from scratch a viable option.

Under de senaste åren har användningen av interna sociala nätverk (ISN) markant ökat. En orsak till detta kan vara den ökade användningen av publika sociala nätverk (så som Facebook eller Twitter) på arbetstid, då detta tenderar att sänka arbetsmoralen och effektiviteten hos de anställda. Ett ISN fungerar i princip som ett socialt medium, men dock innanför ett företags eller organisations interna väggar och fokuserar mer på att främja samarbete, kommunikation och kunskapsutbyte. Detta examensarbete utreder hur man kan implementera ett ISN i en mindre organisation och få det att leva i ett företags vardag. Vanligtvis används ISN inom större företag för att främst hitta och dela kunskap inom organisationen.I denna avhandling kommer jag (baserat på genomförda metoder) skräddarsy ett gränssnitt för Xtractor Interactive AB i ett ISN som heter Totara Social. Studien kommer att fokusera på tre olika faktorer som är utvecklade för att motivera användningen av interna sociala nätverk, i syfte att skapa mervärde för de anställda i den dagliga verksamheten. / In recent years, the use of internal social networks (ISN) has significantly increased. One reason for this may be due to the increased use of public social networks (such as Facebook or Twitter) during working hours. This tends to lower the morale and efficiency of employees. An ISN basically acts as a social medium fixed inside a company or organization's internal walls and focuses more on promoting cooperation, communication and exchange of knowledge. As one would implement an ISN within a corporation to mainly find and share knowledge. This thesis investigates how to implement an ISN in a smaller company and getting it to live within the organization. In this thesis, I will (based on the conducted methods) customize an interface for Xtractor Interactive AB in an ISN called Totara Social. The study will focus on three different factors that are developed to motivate the use of the internal social networks, in order to add value to the employees in everyday business.

Podocarpus cunninghamii is an endemic New Zealand conifer that, in pre-human times, formed extensive forest communities across the eastern South Island high country. Anthropogenic disturbances have reduced the distribution of Podocarpus cunninghamii communities such that they now exist mainly as small and isolated remnants within a highly modified, predominantly pastoral landscape. Very little is known of the ecology of high country Podocarpus cunninghamii communities, and without this information it is not possible to develop an ecological basis for their restoration. This thesis explores the ecology of Podocarpus cunninghamii in the eastern South Island high country, investigating factors that potentially affect the restoration of Podocarpus cunninghamii within this environment, with special attention paid to the role of arbuscular mycorrhizal fungi (AMF). Field investigations of Podocarpus cunninghamii communities showed that they contain a high degree of floristic and structural variation determined by soil and climatic variables. Analysis of age and size class distributions suggest that Podocarpus cunninghamii has more than one regeneration strategy, and can regenerate within intact forest following the opening of small canopy gaps or can undergo large-scale recruitment following catastrophic disturbance. Field and glasshouse experiments investigating growth and nutrient responses of Podocarpus cunninghamii to different AMF inoculants found that Podocarpus cunninghamii responses are dependent on both AMF type and grass competition. Finally, investigation of Podocarpus cunninghamii carbon stocks showed that they are less than that of other New Zealand forest types, but are greater than that of grazed pastures. Successful restoration of high country Podocarpus cunninghamii communities will require the incorporation of associated species based on local environmental conditions, and will also need to allow for disturbance processes. AMF may have an important role to play in restoration by reducing seedling production times and by increasing the competitiveness of Podocarpus cunninghamii when in competition with exotic grasses.

Although species maintenance in small forest fragments relies on successful regeneration and recruitment, few studies have examined the effects of fragmentation on regeneration processes. New Zealand's podocarp species rely on large disturbance openings operating across a vegetated landscape to stimulate regeneration. Clearance of vegetation that results in small fragments of forest removes regeneration opportunities for podocarps by destroying the intact vegetation mosaic, and as a result may exclude disturbances of the scale necessary for podocarp regeneration. Fragmentation alters the disturbance regime of the landscape, with important implications for the regeneration of podocarps on Banks Peninsula. The four remaining lowland podocarp-hardwood fragments on Banks Peninsula were sampled to determine the structure and regeneration patterns of podocarps and to assess their long term viability. Density, basal area, and size and age class distributions were used to examine current composition, and in conjunction with spatial analysis, to identify past regeneration patterns and infer likely future changes in composition and population structure. Podocarp size and age class structures for three of the four fragments were characteristically even-sized and relatively even-aged (eg; Prumnopitys taxifolia c. 350 to 600 years), with little or no regeneration for approximately the last 200 years (old-growth fragments). Regeneration of the current podocarp canopy in the old-growth fragments may have been stimulated by flooding. The fourth younger fragment showed much more recent regeneration with Prumnopitys taxifolia, Podocarpus totara and Dacrycarpus dacrydioides mostly 80-160 years old, and substantial populations of seedlings and saplings, probably as a result of anthropogenic fire. In the absence of major disturbance the podocarp component in forest fragments on Banks Peninsula is likely to decline with composition shifting towards dominance by hardwood species. There is some evidence to suggest that canopy collapse will stimulate some podocarp regeneration within the fragments, however it appears to be unlikely that podocarps will persist on Banks Peninsula indefinitely within the fragments studied. There is an urgent need for more quantitative research in New Zealand fragmentation literature, and a need for more emphasis on processes. Banks Peninsula offers potential for a more landscape scale approach in forest management, and the maintenance of regenerating scrub in pockets about the Peninsula may offer the regeneration opportunities for podocarps that are lacking within protected fragments. My study took a quantitative approach in examining the effects of forest fragmentation on the demographics of podocarps and compositional change in forest fragments on Banks Peninsula.
