Focus on the proposal
Th is thesis is about how to create communicative images. It
is mainly for landscape architects. With communicative
images, I mean images created with the purpose to
communicate a proposal or idea in a direct way to. By only
looking at the image, the viewer should get an idea of what
the proposal entails. A communicative image should also
create an interest in the proposal. I have chosen to write
about this topic because it is a big part of a landscape
architects profession and there are many diff erent aspects to consider. As a landscape architect create images as part of a context, and in order to communicate or develop an idea.
The pictures should show an imaginary future and is an
image of what a place is expected to become. It diff ers in this way, for example from an artist or a photographer's work, where the image itself is oft en the fi nal product. Landscape architect thus has diff erent requirements on what their images communicate.
The purpose of this thesis is to fi nd the tools to present
proposals and ideas through images. To achieve the purpose, I have formulated two questions:
âą What is the purpose of a visual presentation of a design
proposal in landscape architecture?
âą What is important to keep in mind when you want to
create a communicative picture?
The thesis is based on literature studies, interviews and
analysis of architectsâ images. The literature studies and
interviews gave me a background to what is important to
think about when you present a proposal using images. It
also gave me knowledge and how to make the work of create
images eff ectively. I then summarized this background with a list of items to take into consideration when creating images.
To develop and customize the items to suit a landscape
architects work with images, I used them for the analysis of
images, taken from presentations of architect competitions in landscaping. Th e images are fetched from completed
competitions published at Swedish architects website. Th e
choice of images was based on whether the communicative
image from the contest presentation caught my interest or
not. Aft er the analysis, I came up with six tools that can be used to present proposals and ideas with the help of images.
To investigate how the tools work in practice, I use them as
help in the creation of my own perspective. I used a proposal I made earlier in the program. I created several
communicative image of this proposal and examined thus
diff erent ways to interpret the tools.
Th e tools I came up with are the following:
âą Focus on the proposal - Let the proposal help to guide the
design of the image by always having the proposal in focus.
It is also important to understand the context in which the
image is created, where the target audience, stage and type of
projects are important aspects to consider.
âą Space for imagination - Decide how much space the
viewer should to have to fi ll in with their own imagination.
In a perspective where everything is exactly reproduced and
anchored and where details and folklore are carefully
plotted, it is diffi cult to add your own associations. A
perspective with much empty space or details that are
diffi cult to interpret, it can be easy to fi ll in with their own
imagination, but diffi cult to understand what its author
intended.
âą Viewing angle - Select a viewing angel that display the
proposal and highlights it in a positive way. Show parts that
are important for the proposal and select the angle based on
how much you wish shown in the image. A bird's eye view
gives such a large scale, with less opportunity to detail.
âą Dynamics and balance - Place deliberately out various
details with the desired direction, to thereby create dynamic
or harmonic images. Images with even large areas give a
balanced perspective. Th e selected angle can also aff ect the
image dynamics and balance. Given directions can then be
reinforced or counteracted by the addition of details and
movement.
âą Contrasts and color - Use contrasts and colors to create
eff ects and highlight desired objects. It provides a perspective
that draws attention.
âą Details and scale fi gures- Th ink about how to use details.
An image with too much information and details can appear
cluttered and is easily misinterpreted. Remove anything that
takes the focus off what is to be communicated and select the details that fi ll a purpose in the image. Scale Figures in the form of people facilitates the understanding of the image, the features on the site and create atmosphere
Development of adenoviral vectors for monitoring telomerase activity in living cells
ABSTRACT Telomerase activity is a potential molecular marker for cancer and primitive cells in regenerative tissues. The most commonly used method to measure telomerase activity in cells is the telomerase reverse amplification protocol (TRAP) assay, where the protein extracts derived from homogenized cells are analysed. In this thesis we focused on developing a method where telomerase activity could be monitored and used to separating cells with high telomerase activity without killing them. We used the promoter sequence of human telomerase reverse transcriptase (hTERT) for transcriptionally controlling a destabilised green fluorescence protein (d2EGFP) reporter gene since there is a strong correlation between hTERT transcriptional activity and telomerase activity in cells. Moreover, we chose to work with adenoviral vectors due to their high level of transient gene expression as a gene transfer system. Unfavourably, adenoviral vector transduction of tumour cells has been hampered by low expression of the coxsackie B and adenovirus receptor (CAR) on the host cells, which is the attachment receptor for the most commonly used adenoviral vector (Ad5). Thus, we used a fibre-modified Ad5 vector with the tropism of Ad35, which uses the ubiquitously expressed CD46 protein as attachment receptor. We transduced a variety of cell lines with the developed hTERT-d2EGFP vector and demonstrated a close correlation between expression levels of the d2EGFP, endogenous telomerase activity, and hTERT mRNA expression. Furthermore, the hTERT-d2EGFP reporter vector was able to monitor the cell cycle and differentiation stage-dependent hTERT transcription activity. Additionally, in order to study the self-renewal process of haematopoietic stem cells (HSCs), we utilised the hTERT-reporter vector for monitoring hTERT transcription activity in human HSCs. Interestingly, increasing hTERT expression was inversely correlated to the self-renewal capacity among primitive HSCs and the hTERT-reporter vector could be used to separate short-term from long-term re-populating human HSCs. In summary, we have developed a versatile adenoviral vector system with Ad35 tropism, which can be used to transiently transduce tumour cells as well as haematopoietic cells. This vector system can be used to study normal regulation of hTERT and has potential in development of novel therapeutic approaches for treatment of tumours and malignancies in the blood system

BMI and mortality in patients with new-onset type 2 diabetes: a comparison with age- and sex-matched control subjects from the general population
Objective: Type 2 diabetes is strongly associated with obesity, but the mortality risk related to elevated body weight in people with type 2 diabetes compared with people without diabetes has not been established.
Research Design and Methods: We prospectively assessed short- and long-term mortality in people with type 2 diabetes with a recorded diabetes duration â€5 years identified from the Swedish National Diabetes Registry between 1998 and 2012 and five age- and sex-matched control subjects per study participant from the general population.
Results: Over a median follow-up of 5.5 years, there were 17,546 deaths among 149,345 patients with type 2 diabetes (mean age 59.6 years [40% women]) and 68,429 deaths among 743,907 matched control subjects. Short-term all-cause mortality risk (â€5 years) displayed a U-shaped relationship with BMI, with hazard ratios (HRs) ranging from 0.81 (95% CI 0.75-0.88) among patients with diabetes and BMI 30 to <35 kg/m2 to 1.37 (95% CI 1.11-1.71) with BMI â„40 kg/m2 compared with control subjects after multiple adjustments. Long-term, all weight categories showed increased mortality, with a nadir at BMI 25 to <30 kg/m2 and a stepwise increase up to HR 2.00 (95% CI 1.58-2.54) among patients with BMI â„40 kg/m2, that was more pronounced in patients <65 years old.
Conclusions: Our findings suggest that the apparent paradoxical findings in other studies in this area may have been affected by reverse causality. Long-term, overweight (BMI 25 to <30 kg/m2) patients with type 2 diabetes had low excess mortality risk compared with control subjects, whereas risk in those with BMI â„40 kg/m2 was substantially increased

A field study of management stress in reindeer (Rangifer tarandus L)
The impact of stress was studied in semidomesticated reindeer subjected to various herding and handling methods. In herded and handled animals, stress lesions were found, such as abomasal haemorrhage, muscular and myocardial degeneration and marked changes in blood constituents. The degree of change was dependent of the magnitude of stress the animal had been exposed to. Manual handling and restraint was found to be one of the major stress factors. There were evident indications of a cumulative effect of repeated stress events. The use of motor vehicles (helicopter and snow-scooter), for herding and transporting the animals, was found to be an important stress factor. It is concluded that various herding and handling methods studied in the present investigation led to varying degrees of deleterious effects on the health of the animals and a poorer meatquality from slaughtered animals. Hence herding should be undertaken as carefully as possible, the time taken for manual handling should be minimized, and the corrals be so constructed as to cause a minimum of disturbance, capture and restraint. Transportation should be undertaken very cautiously with as little manual handling as possible during loading and unloading. To obtain a good meat quality, animals to be slaughtered should be subjected to a minimum of handling, i.e. slaughter should take place as quickly as possible. Transportation of live animals to slaughterhouses and the keeping of animals in corrals, pens or crates whilst awaiting slaughter will result in a lowered meat quality and should therefore be avoided.En fåltstudie av stress hos ren i samband med olika hanteringsformer.Abstract in Swedish / Sammanfatning: Betydelsen av stress hos ren studerades i hjordar i vilka olika typer av samlings- och hanteringsmetoder anvandes. I samtliga hjordar som utsatts for olika former av drivning forelag hos slaktdjur skador betingade av stress i form av magblodningar, muskelsonderfall och forandringar i blodbilden. De funna skadorna och forandringarna var beroende av den grad av stress som djuren utsatts for. Manuell hantering och inskrankning av djurens rorelsefrihet befanns vara en av de huvudsakliga stressfaktorerna. Det forelag åvenledes en stark indikation på en kumulativ effekt av upprepad stress. Anvandning av motorfordon (helikopter, snoskoter) vid drivning samt vågtransport av levande djur befanns vara betydande stressfaktorer. Det kan fastslås att de olika hanteringsformerna inneburit olika grader av stress. Graden av stresspåverkan innebår olika grader av negativa effekter dels allmånt for djurens hålsotillstånd dels for en forsåmrad kottkvalitet. Sålunda bor drivningar foretagas så forsiktigt som mojligt och tiden for manuell hantering goras så kort som mpjlig. Dårtill bor gårdor konstrueras så att yttre storning, manuell hantering och begrånsning av djurens rorelsefrihet minimeras. Transporter bor genomforas med forsiktighet och med undvikande av manuell hantering vid lastning och lossning. Slakt bor foretagas omedelbart, dvs vid gårdan. Transport av levande djur, samt hållandet av djur i gårdor eller fillor i vantan på slakt innebår att kottkvaliteten forsåmras och bor således undvikas.Kenttâtutkimus porojen stressistâ erilaisten kâsittelymuotojen yhteydessà.Abstract in Finnish / Yhteenveto: Stressin merkitystâ poroissa tutkitaan laumoissa, joissa kàytetààn erilaisia kokoamis - ja kàsittelymenetelmià.

Svenskt Sigill : the strengths and weaknesses of a quality label
Marknadssituationen för svenska livsmedelsproducenter blir allt hÄrdare i och med fokuseringen pÄ lÄgpris och EMV samt ökad import. För att lyfta fram de mervÀrden, som finns i svenska livsmedel, kan producenter mÀrka sina produkter med kvalitetsmÀrket Svenskt Sigill. MÀrket garanterar att rÄvarorna har producerats pÄ svenska kontrollerade gÄrdar, som lever upp till höga krav pÄ sÀkra livsmedel, god djuromsorg, miljöansvar och öppna svenska landskap. Konsumenter, som vÀljer Svenskt Sigill-mÀrkta produkter, ska kÀnna sig trygga.
Studiens syfte Àr att identifiera starka och svaga sidor hos Svenskt Sigill sÄsom ett kollektivt nyttjat varumÀrke, sett ur en producentsynvinkel, varvid olika producenters specifika förutsÀttningar mÄste tas i beaktande.
Studien bygger pÄ tre teorier, nÀmligen strategiteori, varumÀrkesteori samt agentteori. Dessa teorier ligger till grund för formuleringen av ett antal hypoteser, frÄn vilka frÄgor hÀrleds till den frÄgeguide som anvÀnds vid intervjuerna. Intervjuer genomfördes med sakkunniga pÄ 15 företag, varav fem Àr anslutna, sju Àr icke-anslutna till Svenskt Sigill och tre producenter anvÀnder sig endast av certifieringssystemet men inte av mÀrket.
Av intervjuerna framgĂ„r att Svenskt Sigills egenskaper inte Ă€r tillrĂ€ckligt unika, och mĂ€rket Ă€r dĂ€rmed inte det konkurrensvapen de anslutna producenterna önskar att det skulle vara. De, som kan stĂ€rkas av mĂ€rkningen, Ă€r de smĂ„ producenterna med relativt okĂ€nda varumĂ€rken, vilka idag inte signalerar svenskhet i sin marknadsföring. Ăven produkter, som Ă€r utsatta för hĂ„rd konkurrens frĂ„n EMV, samt produkter, som konsumenter inhandlar slentrianmĂ€ssigt, kan gynnas av att mĂ€rkas med Svenskt Sigill. Stora livsmedelsproducenter med starka egna varumĂ€rken, som redan signalerar svenskhet och kvalitet, ser inga fördelar med kvalitetsmĂ€rket Svenskt Sigill.
En av styrkorna med Svenskt Sigill Àr att mÀrket anvÀnds inom mÄnga produktkategorier. De intervjuade producenterna tror dock att mÀrket skulle stÀrkas ytterligare, om det Àven fanns pÄ kött- och kycklingprodukter. Man vill Àven att mÀrket ska synas pÄ starka varumÀrken för att fÄ bÀttre spridning och kÀnnedom om det. Beroende pÄ om en konkurrent Àr ansluten eller om man Àr ensam att anvÀnda Svenskt Sigill inom sin produktkategori, Àr mÀrkets konkurrenskraft olika stark. Att en konkurrent Àr ansluten behöver inte automatiskt vara negativt, vilket man lÀtt kan anta, det kan vara till fördel beroende pÄ vilken bransch man befinner sig i. Svenska livsmedelsbranscher med smÄ marknadsandelar Àr mÄnga gÄnger tvungna att hÄlla varandra om ryggen, för att möta konkurrensen frÄn import och EMV. De skulle inte överleva om de ocksÄ försökte konkurrera ut varandra. I de flesta branscher vill man dock inte att konkurrenter ansluter sig eftersom det Àr dem man försöker differentiera sig ifrÄn.
I och med att Svenskt Sigill Àr ett kollektivt nyttjat kvalitetsmÀrke mÄste samtliga anslutna producenter fokusera pÄ kvalitet sÄ att inte mÀrket fÄr dÄligt rykte vilket kan pÄverka de anslutna producenterna negativt.
Kostnaden för mĂ€rkningen ligger inte till grund för producenternas beslut om de ska ansluta sig. Ăgandet av företaget Svenskt Sigill vĂ€ger inte heller tungt, dĂ„ sĂ„dana beslut tas. Det som avgör om man ska ansluta sig Ă€r det förvĂ€ntade mervĂ€rde, som produkterna kan fĂ„ genom att mĂ€rkas med Svenskt Sigill.The market situation for Swedish food producers is gradually becoming harder because of an
increased focus on low prices, retailersâ own brands, and increasing imports. To highlight the
values of Swedish food, producers can label their products with the quality brand Svenskt
Sigill. This brand guarantees that the raw products are produced on Swedish certified farms,
and that they fulfill high demands on food safety, animal ethics, environmental concerns and
open Swedish landscapes. Consumers who buy products labelled Svenskt Sigill should feel
safe.
The aim of this study is to identify the strengths and weaknesses of Svenskt Sigill as a
collectively used brand from a producer perspective where different producersâ specific
prerequisites are taken into acount.
This study is founded on three theories; strategic theory, branding theory and agency theory.
Based on these theories a number of hypotheses are extracted, from which questions are
formulated to a question guide used during the interviews. Interviews were undertaken with
fifteen companies, of which five presently use the Svenskt Sigill label, seven are not linked to
Svenskt Sigill and three producers use only the certifications system of Svenskt Sigill but not
the label.
The interviews indicate the image of Svenskt Sigill is not unique enough and the brand is
therefore not considered to be the tool that the producers wish it to be. The firms who can
benefit from the label are mainly small food producers with relatively anonymous brands, not
highlighting Swedish origin in their marketing. Also products that are exposed to intense
competition from retailerâs own brands and products which the consumer buys spontaneous
can benefit from using Svenskt Sigill. Major food producers with strong brands signalling
Swedish origin and high quality do not see any benifit with the quality brand Svenskt Sigill.
One of the strengths with Svenskt Sigill is that the brand is represented in many product
categories . The producers thinks that the brand would be even stronger if also meat and
chicken products were labelled. They also want strong, well-known brands to use the quality
brand Svenskt Sigill to accomplish better reach and knowledge of it. Depending on whether a
competitor uses the Svenskt Sigill label, or if the producer is the only one to use it in the
product category, the competitive power has different strength. The fact that a competitor uses
the brand is not necessarily negative. It can be positive depending on which line of business
they are in. Food businesses with small market shares often have to support each others in
order to meet the competition from imports and retailersâ own brands. In most businesses,
though, the producers do not want competitors to use the brand, since the producers want to
differentiate their products from each others.
Since Svenskt Sigill is a collectively used quality brand, all the producers must focus on
quality so that the label does not get bad reputation, which could affect the other connected
producers negatively.
The cost of the labelling is not a determining factor when decisions are made about whether to
use the label Svenskt Sigill. Neither is the ownership of the company Svenskt Sigill important
when such decisions are made. What matters when the producers decide whether to use the
label, is the expected added value that their products get when labelled Svenskt Sigill
