Geoprocessing journey-to-work data : delineating commuting regions in Dalarna, Sweden

Delineation of commuting regions has always been based on statistical units, often municipalities or wards. However, using these units has certain disadvantages as their land areas differ considerably. Much information is lost in the larger spatial base units and distortions in self-containment values, the main criterion in rule-based delineation procedures, occur. Alternatively, one can start from relatively small standard size units such as hexagons. In this way, much greater detail in spatial patterns is obtained. In this paper, regions are built by means of intrazonal maximization (Intramax) on the basis of hexagons. The use of geoprocessing tools, specifically developed for the processing ofcommuting data, speeds up processing time considerably. The results of the Intramax analysis are evaluated with travel-to-work area constraints, and comparisons are made with commuting fields, accessibility to employment, commuting flow density and network commuting flow size. From selected steps in the regionalization process, a hierarchy of nested commuting regions emerges, revealing the complexity of commuting patterns.

En studie om rehabilitering - en skamgörande process

The purpose of this essay is using theories about labeling and social bonds to study whether a measure of rehabilitation for the psychically disabled contributes to a return to a normal status as not-labeled. Partly we examine whether the activities organized by the regulation-ruled authorities during the work of rehabilitation lead to shame or pride, and partly how these activities are organized regarding the processes that lead to the emotions pride or shame among the participants. Method: qualitative semi-structured face-to-face interviews with professional rehabilitation-actors at the Public Employment Office (PEO), the Social Insurance Office (SIO), the Social Service (SOS), the Psychiatry and the Division of Labour Market (AME).Conclusions: the Psychiatry clients are treated with respect, may participate, and communication is characterized by attunement, therefore strong social bonds can be built. On the contrary, among the other examined activities, we found many elements that arouse shame. Since these are more ruled by regulations, the result is engulfment and demands on conformity, because the compromise-possibilities are almost non-existent. Psychically disabled persons are met by prejudice, ignorance, disrespect and a non-solidarity-language. To get help, the individual has to accept a label in form of a diagnosis, and this labeling leads to a negative self-image. Furthermore the psychically disabled persons are falling between two chairs because of a weak cooperation between the rehabilitation-actors. Bimodal alienation and triangulation contributes to the difficulties in cooperation.Result: the social bonds are not strong enough to achieve a rehabilitation-effect. Even if the treatment from each administrator is important, we find the explanation-level primarily in laws, rules and government, because the structure rules the rehabilitation-measures, with shame as a consequence. Since we found elements of shame institutionalized in the way of working at PEO, SIO, SOS and AME, it means that social bonds can never reach a level good enough for achieving pride and normalization from a deviance or labeled identity.

Use Multilevel Graph Partitioning Scheme to solve traveling salesman problem

The traveling salesman problem is although looking very simple problem but it is an important combinatorial problem. In this thesis I have tried to find the shortest distance tour in which each city is visited exactly one time and return to the starting city. I have tried to solve traveling salesman problem using multilevel graph partitioning approach.Although traveling salesman problem itself very difficult as this problem is belong to the NP-Complete problems but I have tried my best to solve this problem using multilevel graph partitioning it also belong to the NP-Complete problems. I have solved this thesis by using the k-mean partitioning algorithm which divides the problem into multiple partitions and solving each partition separately and its solution is used to improve the overall tour by applying Lin Kernighan algorithm on it. Through all this I got optimal solution which proofs that solving traveling salesman problem through graph partition scheme is good for this NP-Problem and through this we can solved this intractable problem within few minutes.Keywords: Graph Partitioning Scheme, Traveling Salesman Problem.

The attractiveness of the work is affected when production of handcrafted log houses moves indoors

Viewed from a historical perspective, a shift has occurred within the forestry and wood sector towards indoor work. In Sweden, the production of handcrafted log houses has now also begun to move indoors. With a point of departure in development processes within the log house sector involving working indoors, education, work attractiveness, between 2001-2005, the aim of this study was to compare indoor work with outdoor work, based on log house builders' experience of working on handcrafted log houses. Methods used in the interactive development project involving apprentices, experienced log house builders and researchers, were participation with continuous documentation of experiences and opinions; questions; interviews; and measurement of the work environment. The Attractive Work Model has been used in order to analyse perceptions and values. The changes, 15 out of 22 areas, were perceived both negatively and positively. Therefore, it can not be said that working on traditional, handcrafted log houses becomes more attractive if it is moved indoors. The majority wanted to work both outdoors and indoors, while most of the others only wanted to work outdoors. The results indicate that there is scope for developing more attractive work indoors by utilising experiences from log house builders and closely related activities such as the forestry and wood sector. Changes made within one area of work attractiveness affect other areas. Further research is needed both with regard to comparisons between indoor and outdoor work and regarding the interaction between the areas that are identified in the Attractive Work Model.

Att bli, att vara och att ha varit - om ingångar i och utgångar ur Jehovas vittnen i Sverige

Summary To become, to be and to have been: about the  Jehovah’s Witnesses The Watchtower Bible and Tract Society, in the following text referred to as the Jehovah’s Witnesses or “the organisation”, is a worldwide Christian organisation with about 6.7 million members. The organisation has many times, without any success so far, proclaimed Armageddon when they expect Jehovah to return to Earth. They interpret the Bible in their own, often very literal way, and require their members to live according to these interpretations. Among the consequences of this, members are forbidden to vote, to do military service or to receive blood transfusions. Apart from attending the three weekly meetings, members are expected to be active in missionary work, known as “publishing”. If a member fails to do a certain number of hours’ publishing, he or she risks being deprived of active membership status Sweden in general is considered to be a society where the population is not very religious. The formerly state-governed Lutheran church has lost its influence and the vast majority of ordinary Swedes do not visit church on other occasions than weddings, funerals or christenings. Expressing one’s own religious values has become somewhat of a private matter where publicity is seldom appreciated, which is contrary to the practice of the Jehovah’s Witnesses. This is one of the reasons why the Jehovah’s Witnesses are commonly perceived by average Swedes as a “suspicious” religious organisation. The aim and methods of the study This dissertation seeks to describe and investigate the entering and leaving of a highly structured and hierarchical religious community, exemplified in this case by the Jehovah’s Witnesses. What are the thoughts and aspirations of someone who is considering becoming a Jehovah’s Witness? What are the priorities and what experiences seem important when a person is going through such a process? And when this person has finally reached his or her goal of becoming a member, is it the same motivation that makes him or her stay in the organisation for longer periods of time, possibly for the rest of their lives, or does it change during the process of entering, or does this motivation change its character during the transition from entering to being a regular member? Why do some of the members change their attitude to the Jehovah’s Witnesses from rejoicing to bitterness? And how does this process of exit manifest itself? In what way is it different from the process of entry? The respondents in this study were chosen from both active members of the Jehovah’s Witnesses in Sweden and those who have left the organisation for personal reasons. Repeated interviews with ten active members of the organisation have been conducted in the course of the study and compared to equal numbers of former members. The interviews have been semi-structured to deal with questions of how a person has come into contact with the organisation; how they retrospectively experienced the process of entry; the reasons for becoming a member. Questions have also been asked about life in the organisation. The group of “exiters” have also been asked about the experience of leaving, why they wanted to leave, and how this process was started and carried out. In addition to this I have analysed a four-year diary describing the time inside and the process of leaving the organisation. This has given me an extra psychological insight into the inner experience of someone who has gone through the whole process. The analysis has been done by categorising the content of the transcribed interviews. An attempt to outline a model of an entry and exit process has been made, based on ideas and interpretations presented in the interviews. The analysis of the diary has involved thorough reading, resulting in a division of it into four different parts, where each part has been given a certain key-word, signifying the author’s emotional state when writing it. A great deal of the information about the Jehovah’s Witnesses has been collected through discussion boards on the Internet, informal talks with members and ex-members, interviews with representatives of the organisations during visits to its different offices (Bethels), such as St. Petersburg, Russia, and Brooklyn, New York, USA. The context Each organisation evolves in its own context with its own norms, roles and stories that would not survive outside it. With this as a starting point, there is a chapter dedicated to the description of the organisation’s history, structure and activities. It has been stated that the organisation’s treatment of its critical members and the strategies for recruiting new members have evolved over the years of its history. At the beginning there was an openness allowing members to be critical. As the structure of the organisation has become more rigid and formalised, the treatment of internal critics has become much less tolerated and exclusion has become a frequent option. As a rule many new members have been attracted to the organisation when (1) the day of Armageddon has been pronounced to be approaching; (2) the members of the organisation have been persecuted or threatened with persecution; and (3) the organisation has discovered a “new market”. The processes for entering and exiting How the entering processes manifest themselves depends on whether the person has been brought up in the organisation or not. A person converting as an adult has to pass six phases before being considered a Jehovah’s Witness by the organisation. These are:  Contact with the Jehovah’s Witnesses, Studying the bible with members of the organisation, Questioning, Accepting, Being active as publisher (spreading the belief), Being baptised.  For a person brought up in the organisation, the process to full membership is much shorter:   Upbringing in the organisation, Taking a stand on the belief, Being baptised. The exit process contains of seven phases:   Different levels of doubts, Testing of doubts, Turning points, Different kinds of decisions, Different steps in executing the decisions, Floating, a period of emotional and cognitive consideration of membership and its experiences, Realtive neutrality.   The process in and the process out are both slow and are accompanied with anguish and doubts. When a person is going through the process in or out of the organisation he or she experiences criticism. This is when people around the adept question the decision to continue in the process. The result of the criticism depends on where in the process the person is. If he or she is at the beginning of the process, the criticism will probably make the person insecure and the process will slow down or stop. If the criticism is pronounced in a later phase, the process will probably speed up. The norms of the organisation affect the behaviour of the members. There are techniques for inclusion that both bind members to the organisation and shield them off from the surrounding society. Examples of techniques for inclusion are the “work situation” and “closed doors”. The work situation signifies that members who do as the organisation recommends – doing simple work – often end up in the same branch of industry as many other Jehovah’s Witnesses. This often means that the person has other witnesses as workmates. If the person is unemployed or moves to another town it is easy to find a new job through connections in the organisation. Doubts and exclusions can lead to problems since they entail a risk of losing one’s job. This can also result in problems getting a new job. Jehovah’s Witnesses are not supposed to talk to excluded members, which of course mean difficulties working together. “Closed doors” means that members who do as the organisation recommends – not pursuing higher education, not engaging in civil society, working with a manual or in other way simple job, putting much time into the organisation – will, after a long life in the organisation, have problems starting a new life outside the Jehovah’s Witnesses. The language used in the organisation shows the community among the members, thus the language is one of the most important symbols. A special way of thinking is created through the language. It binds members to the organisation and sometimes it can work as a way to get back into the normative world of the organisation. Randall Collins’s (1990, 2004) thoughts about “emotional energy” have enabled an understanding of the solidarity and unity in the organisation. This also gives an understanding of the way the members treat doubting and critical members. The members who want to exit have to open up the binding/screening off. A possible way to do that is through language, to become aware of the effect the language might have. Another way is to search for emotional energy in another situation. During the exit process, shame might be of some importance. When members become aware of the shame they feel, because they perceive they are “acting a belief”, the exit process might accelerate.

Effective measures to decrease air contaminants through risk and control visualization : a study of the effective use of QR codes to facilitate safety training

Woodworking industries still consists of wood dust problems. Young workers are especially vulnerable to safety risks. To reduce risks, it is important to change attitudes and increase knowledge about safety. Safety training have shown to establish positive attitudes towards safety among employees. The aim of current study is to analyze the effect of QR codes that link to Picture Mix EXposure (PIMEX) videos by analyzing attitudes to this safety training method and safety in student responses. Safety training videos were used in upper secondary school handicraft programs to demonstrate wood dust risks and methods to decrease exposure to wood dust. A preliminary study was conducted to investigate improvement of safety training in two schools in preparation for the main study that investigated a safety training method in three schools. In the preliminary study the PIMEX method was first used in which students were filmed while wood dust exposure was measured and subsequently displayed on a computer screen in real time. Before and after the filming, teachers, students, and researchers together analyzed wood dust risks and effective measures to reduce exposure to them. For the main study, QR codes linked to PIMEX videos were attached at wood processing machines. Subsequent interviews showed that this safety training method enables students in an early stage of their life to learn about risks and safety measures to control wood dust exposure. The new combination of methods can create awareness, change attitudes and motivation among students to work more frequently to reduce wood dust.
