Simulation of rattan harvests in Indonesia : different harvesting pressures and the resulting patterns

The objectives of this research were to determine whether the natural rattan resources in Sulawesi, Indonesia can cope with the strongly increased harvesting pressure that has occurred over the last centuries. I was furthermore looking for patterns in the rattan population dynamics that might give a hint on how the harvesting system could be improved to ensure a maximum sustainable yield. To answer these questions, I developed an individual-based model to analyse the dynamics of rattan growth in connection with rattan harvests by locals to identify sustainable levels of rattan harvests around villages in Sulawesi, Indonesia. Scenarios with different harvesting intensities were run to compare the change in harvest amount. For a given harvesting pressure, scenarios with a high number of harvesters and a low harvesting frequency had the same effect as scenarios with high harvesting frequencies and a low number of harvesters.

Skogsåkeriägares inställning till organisationsförändringar :

There are two groups of haulage contractors in roundwood transport , those who are contracted direct by the transport buyer and those who are connected to a freight company which in its turn is contracted by the transport buyer. Today the roundwood haulage is dominated by contractors with one to two lorries. The effort of coordinating transportation for a transport buyer is dependent on how many communication contacts that must be managed (how many individual haulage contractors the transport buyer has to work with). A structural change in the sector that leads to a decrease in the number of haulage contractors but an increase in the capacity of each contractor, makes it possible for a transport buyer to coordinate transports with fewer communication contacts. The reason why a company reaches a certain size can be explained by the number of contracts it makes and manages.

Självmord och självskadebeteende : en studie om självmord och självskadebeteende inom Svensk kriminalvård 2002- 2012.

During the period 2002-2012, 74 people committed suicide within the Swedish judicial system. During the same period of time 702 self-destructive actions and suicide attempts were reported. The purpose of this work was to investigate and illuminate the causes which are responsible for individuals committing suicide while in custody or in prison. The theory of this  work is an ethnographic study of a special social context. A study of literature, statistics and earlier scientific research was used in this study.

3D-skrivarens intåg i immaterialrätten : - Om 3D-bilder, 49 § URL och vikten av lämpliga avtalslicenser

The current study aimed to test the public self-consciousness impact on creative performance. An experimental design was used in which 40 participants were randomly assigned to two groups, one of which was the experimental group and the other was the control group. A mirror was used in the experimental group to induce public self-consciousness among the participants while they performed creativity tests. A consequence test was used where the participant had to give suggestions for the given scenario "What would happen if everyone became blind?" which was then measured in the number of proposals (fluency).

Testikelmått och daglig spermieproduktion hos svenska halvblodshingstar :

Testicular measurements and daily sperm output (DSO) are important factors affecting reproductive capacity of stallions. In the present study testicular measurements of 10 Swedish half-blood stallions were determined (height, length, width and volume). Ejaculates were collected from each stallion once daily for 10 days to evaluate some important seminal characteristics: gel-free ejaculate volume, sperm concentration, percent progressively motile spermatozoa and total number of spermatozoa (TSN). The gel-free ejaculate volume was measured with a graduated cylinder, the sperm concentration was counted in a Bürker chamber, the sperm motility was estimated in a phase-contrast microscope and TSN was determined by multiplying the gel-free seminal volume by the sperm concentration. Testicular measurements were as follows (left and right testis): height 7,5 cm and 7,8 cm, length 10,6 cm and 10,8 cm, width 6,5 cm and 6,6 cm, volume 278,2 cm3 and 293,8 cm3, scrotal width 12,3 cm and total testicular volume 572,0 cm3 .

Glidytor och ytjämnhet med avseende på friktion och tätning

Gliding and sealing functions in Öhlins shock absorbing systems sets great demands onthe contacting surfaces. In this particular case, the bushings and the sealings on acylinder piston. The surface wanted is a surface with both low frictional forces and smallleakage. This study was done with the goals of investigating and determining existingsurfaces due to the frictional force and leakage. How can we in an easy mannerdescribe these?A number of ten front forks were part of a main study.

Hur ser elevernas läs- och skrivvanor ut på fritiden?

My curiosity concerning what pupils read and write during leisure time led me to gather information using a quantative method. The study's aim is to investigate which reading and writing habits they have during their time outside school. A comparison was done of pupils at school year level 3 and level 4 in two different schools with the intention of investigating the influence of social background on reading and writing habits. 137 pupils filled in survey forms and thereafter the MYSTAT statistic program was used to process the information. The results point towards that the pupils read story books both more often and for a longer time than any other type of literature and that they read them often or very seldom.

En analys av lärarhandledningar inom biologiämnet och Lpo 94 : en fråga om begränsad undervisningsvariation?

 During our education time, we have heard on several occasions how the high changing rate in the society also influences the education area. That changing process mainly originates from the transform that a school underwent, i.e. the decentralization meaning a delegation of responsibility from a national to local government and the particular school. The main idea that started a changing process goes under the slogan ?a school for everyone?.

Vi-kan-ju-banken -Hälsorelaterat förändringsarbete i arbetslivet (Health promotion in the workplace)

With starting point in the increasing ill-health in Swedish working life today, in form of for example absence due to sickness and early retirement pension, and the knowledge that the working environment effects peoples health in a big extent, I found it very interesting to inquire into how people within the working life experience health promotion and how this can be developed. A qualitative method was used to receive a deeper understanding for the employees? experiences and data was collected through semi structured interviews with employees on a bank called Ikanobanken, in Älmhult. The result shows, among other things, that respondents find responsibility and the opportunity to influence the learning processes and development important. It also became clear that the respondents find participation, motivation, communication and safety essential factors when related to changes in health behaviours.

Kreativitet och offentlig självmedvetenhet : En experimentell sutdie om hur offentlig självmedvetenhet påverkar kreativitet

The current study aimed to test the public self-consciousness impact on creative performance. An experimental design was used in which 40 participants were randomly assigned to two groups, one of which was the experimental group and the other was the control group. A mirror was used in the experimental group to induce public self-consciousness among the participants while they performed creativity tests. A consequence test was used where the participant had to give suggestions for the given scenario "What would happen if everyone became blind?" which was then measured in the number of proposals (fluency).

Mätning av abrasivflöde för vattenskärningsmaskiner

The content of the following report is the summarized result of three students thesis at Blekinge Institute of Technology in co-operation with Water Jet Sweden AB. This report will give the reader a description of principles how to measure the abrasive mass flow in a waterjet cutting system. The work began with a visit to Water Jet Sweden AB to get a closer look at the problem. When the analysis of the problem was done the criteria were defined in the form of demands and desires. The main task of the criteria was to guide the search for the solution. The work proceeded with an extensive search for abrasive flow meters along with obtaining information about flow measurement in general. When the search for abrasive flow meters resulted in nothing all the efforts were concentrated on finding a principle of measurement that could cope with the criteria.

Does tree removal along railroads in Sweden influence the risk of train accidents with moose and roe deer?

After the storm Gudrun in 2005, the Swedish Transport Administration started clear-cutting of railroad corridors to reduce the risk of trees falling down on the tracks. Simultaneously, train accidents with moose and roe deer have become more frequent and the costs for consequent delays and repairs of engines are of growing concern. There is reason to assume that tree-clearance of railroad corridors may have contributed to an increase in number of accidents with moose and roe deer because the cleared areas provide attractive forage and thus may attract wildlife. The objective of my study was to investigate how clearing of trees affected the number of accidents with moose and roe deer. I compared deer-train collision frequencies before and after clearance of the selected railroads and compared these with uncleared control railroads in a BACI (before-after control-impact) approach.

Hormonstörande ämnen och deras effekt på barns hälsa : - Hur ser kunskapen ut hos småbarnsföräldrar?

Endocrine disruptive chemicals (EDCs) are found in many everyday products and can cause adverse effects on human health. Small children are particularly sensitive to EDCs and they are also exposed to them in a greater extent than adults. Despite this, EDCs are only banned in a few toys and childcare products. There are many sources of exposure and if no steps are taken to reduce the incidence of EDCs we may face an increasing number of people diagnosed with obesity, diabetes type 2 or various types of cancer.The Swedish Government has set a number of environmental objectives, one of which is calleda non-toxic environment. The Swedish Chemicals Agency was instructed to produce and conduct a national action plan to achieve this goal.
