Citeringsanalys och citeringsteorier: En kritisk granskning

The purpose of this Masters thesis is to make an outline of different methods and theories within the field of bibliometrics and critically review their strengths and weaknesses. The author studied literature that discussed bibliometric methods and theories. The number of empirical studies that are based on bibliometric methods and theories are numerous and where principally excluded, but some empirical studies were included as part of the argumentation for and against different methods and theories. The author first gives an outline of which methods and theories there are and describes their different strengths and weaknesses. Citation analysis has many different fields of application such as information retrieval, mapping science, evaluative studies and monitoring literature.

Kraftkabelförläggning i mark : - en studie av produktionsmetoder

The assignment given to us by NCC was to compose a degree project based on ground excavations for power cables. The aim of the study was to examine suitable excavation methods depending on different possible terrain conditions. The amount of previously written material within this subject is nearly non- existent and therefore there is a genuine interest by the NCC to receive a compilation of different production methods. The greater part of this study is based upon interviews with several companies active within this area of expertise. The technique of placing the electricity grid beneath ground for safety is today getting more and more common.

Att uppleva historia : eller publik arkeologi i Sydafrika

My thesis is based on a qualitative study in which I have selected six professional teachers in a school in Greater Stockholm, and their views on the phenomenon of conflict management. My questions were the following.How teachers perceive the phenomenon of conflict in the world of school?What strategies do teachers use to resolve conflicts with students?In order to analyze my informants, I have chosen different books that deal with conflict man-agement, policy documents and books on the teaching profession meaning. Through my investigation I found that some teachers used tools and strategies through expe-rience and reflections, and resolve conflicts together or individually. My informants described that there are some teachers how choose to hide and pretend not to see the problem.

Anpassad undervisning till sent anlända elever : Hur ämneslärare på högstadiet anpassar undervisningen till sent anländna elever

This research paper has examined how three teachers in a Swedish state secondary school adapt their teaching to immigrant pupils aged 13 to16 who have recently arrived in the country. The study is based on observation in the classroom and interviews with the teachers. The study showed that all the teachers adapted their teaching methods in the different subjects by actively working with language development during their lessons. The methods employed included explaining words and definitions, using visual methods of teaching and setting frequent written exercises. In this way the pupils developed their language skills whilst covering the subject coursework.

"Förbrända men icke förintade" : en osteologisk analys av kremerade individer från förromersk järnålder från gravfältet Smörkullen, Alvastra, Östergötland

Cremated remains have long been regarded as a highly complex material that often provides unsatisfactory results. This essay discusses the problems that arise when methods commonly used on unburned bone material are used in a cremated skeletal material. The present essay discusses the results from osteological analysis of seven cremations from Pre-Roman Iron Age from a large cemetery in Alvastra, Smörkullen. Several methods were ultimately not applied in the present study as they were insufficient for application on the relevant material. Since the methods were inapplicable and fragments available for gender assessments too low, no sex assessments were made.

Utvärdering av vibrationer inom vattenkrafts normer

The International Organization for Standardization (ISO) proposes vibration standards for the evaluation for machine damage due to vibration in rotational machines, where some vibration parameters are given to measure the vibrationgrade. This work evaluates the relevance of the vibration standards in hydro plants that are proposed by the ISO, and also investigates if there are methods used in other countries could have greater importance. Through statistical analysis of collected data we got a better understanding of relation among different vibration parameters, and also the importance of correct choice of the parameters for the evaluation of vibration. We have found that the vibration standards available today in hydro plants are not reliable for the judgment of vibration?s grade.

Styrkor och svagheter med problembaserat lärande-en metastudie

AbstractProblem-based learning (PBL) was from the beginning developed in medical school, but is today used in education in other programmes as well. Investigations about PBL have been conducted in different disciplines and there is also metastudies. In this paper, a metastudy of 8 bachelor degree papers have been conducted. The questions answered were: which methods were used to investigate PBL in primary, lower secondary and upper secondary school,which advantages were found in working according to the PBL method, which disadvantages were found in working according to the PBL method and did teachers and students views about advantages and disadvantages about PBL as a method differ and if they did, how? The results showed that mostly qualitative methods were used to investigate the PBL as a method, mostly abilities of social qualities and independence were trained in working according to PBL, a disadvantage was that working according to the PBL method was considered more resourse consuming than traditional teaching methods and teachers and students views about PBL did not differ considerably.

Value-at-Risk : Historisk simulering som konkurrenskraftig beräkningsmodell

Value-at-Risk (VaR) is among financial institutions a commonly used tool for measuring market risk. Several methods to calculate VaR exists and different implementations often results in different VaR forecasts. An interesting implementation is historical simulation, and the purpose of this thesis is to examine whether historical simulation with dynamic volatility updating is useful as a model to calculate VaR and how this differs in regard to type of asset or instrument. To carry out the investigation six different models are implemented, which then are tested for statistical accuracy through Christoffersens test. We find that incorporation of volatility updating into the historical simulation method in many cases improves the model.

Byte av systemutvecklingsmetod : En verksamhetsnytta eller en nödvändighet?

 AbstractSystem methodology is in the very heart of system development, it is a crucial part of how you define your work, how you choose to approach the actual problem at hand and how to solve it. Researchers in the system development field has shown that not all methods in theory are in compliance with how it is practiced by the companies who use them. In our thesis we have studied a larger international IT- company and one of their local offices in Sweden, who some years back changed their system development method from a more traditional to an agile one. Our aim of this study has been to establish whether both of these methods has differed between theory and in actual use, and if so, why this has occurred and what the underlying rationality might have been to promote this change. Our questions that we sought to answer were; 1.

Statistisk analys av partiella urladdningar

This thesis concerns partial discharges in stator windings and the possibility of analyzing data using statistical methods. Partial discharges, or PD, are a physical phenomenon in which discharges occur locally due to large electric fields. PD can occur in or adjacent to the insulation of stator windings and causes breakdown of the insulating materials. PD measurement can provide an idea of how widespread the PD activity is. A technique to measure and analyze PD that has become very popular over the last few decades is phase resolved PD patterns.

Anställdas attityder till bibliotek

This paper is about employees' opinion towards libraries. The target group consists of employees at industrial research institutes in Sweden. Libraries offer several more services today than they have done before. I think many people do not recognise all of them and I also think the knowledge and the opinion about libraries have to do with use of them. Since I am curious about if this is true or not the purpose of this essay is to find out, through an attitude research, the employees', at industrial research institutes, opinion about library service.

Berättandets betydelse i förskolan : En undersökning av pedagogers syn på och tillämpning av berättande för att främja barns språkutveckling

AbstractThis study investigates the impact of storytelling for children's language development in preschool from a sociocultural perspective. The purpose is to find what narrative methods teachers use to promote children's language development. I also want to examine whether the children are involved in the storytelling. To get answers to my questions which include what methods teachers use, narrative meaning and function, and their children's participation, I have used qualitative interviews with four preschool teachers at four different preschools.The results of my survey show that teachers use a variety of methods at storytelling. The most common methods were reading, rhymes and daily storytelling while eating.

Fl?ckreducering ? Bl? Vinranka En j?mf?rande studie av tv? efterbehandlingsmetoder vid reng?ring av glaserad keramik

This study explores the effects of two different post-treatment methods on stain reduction in glazed creamware from the late 20th century. The objects stains have been characterized by type one and type two stains which is the result of prolonged contact with food residues, were subjected to the same initial stain reduction. The two post-treatment methods examined are soaking the objects in deionized water and surface rinsing with deionized water. The comparative analysis included photographs under normal and UV-light exposure to assess stain visibility, weight measurements before and after treatments to monitor the absorption and evaporation of liquids, and observations throughout the experiment. The results revealed that while type two stains showed significant alterations after treatments, specifically after soaking, type one stains remained unaffected by both methods.

Development managers are characterized as grassroots bureaucrats, then they are officers who are in the organization, but also has a direct contact with the elderly applicants for municipal assistance. I wanted to explore how these policies relate to the older people's autonomy and their implications for officer assistance in their daily work. As a theoretical starting point I have used out of a närbyråkratiskt perspective, and a negotiation perspective.
