To meet the needs and demands of the costumer, accurate information about how much is available in stock is necessary. When the information in the system does not match the physical inventory, inventory inaccuracy occurs. Inventory inaccuracy is common among companies and may contribute to increased labor cost, excess inventory, production disruptions, waste of time, late deliveries, poor service and lost customers.The purpose of this study is to identify contributing factors to inventory inaccuracy for business with outdoor storage. The study also aims to investigate how efficiency factors can reduce the inventory inaccuracy for business with outdoor storage.A case study was conducted to answer the purpose. A company in the steel industry was chosen to examine inventory inaccuracy on business with outdoor storage.

This is a qualitative analysis that, based on systemic functional linguistics, or SFL, and genre theory, has aimed to study the genre pedagogical implications on written language as they occur in narrative stories and expositions whilst the model is introduced. Systemic functional linguistics is a linguistic theory that views the organisation of language as functional options for meaning; language is a set of resources to channel meaning through realisation. Genre theory elucidates the pragmatic and educational uses of SFL in the categorizing of language in configurations of meanings as they are set and understood in different cultures.  The purpose of the survey is to do so with focus on successful and less successful writers by attempting to answer two primal issues:How is development of written language in reference to the introduction of the genre pedagogical model visible in the studied texts?How does genre pedagogical teaching influence successful and less successful writers as visible in their writing with a certain purpose?To answer these issues the survey is based on narratives and expositions written by high school students who have been divided into two groups according to the purpose of the survey. One text in each genre has been written by the students before and after lessons based on the genre pedagogical learning wheel explaining the relevant genres.

The purpose of this Bachelor thesis in Economics at Lund University is to try to establish the correlation between the value change of retail real estate buildings in Sweden and macro economic variables. The principal method is the multiple regression model and it is used to estimate the basic model. The basic model is enhanced by estimating some 30 models and the result is two good models. The difference between the basic model and the two better models are small but important. In the lagged basic model, the same variables are used as in the basic model but with different time lags.

The purpose of this thesis was to find out what experiences teachers have from using a class blog in teaching. What are the advantages and disadvantages by the use of blogs in education?I have used qualitative interviews with four teachers in grades 1 to 6 who have worked with a class blog in teaching between one and three years.The study has shown that teachers' experience is that the blog serves as motivation and promotes learning for many different pupils and that, together with other digital tools is more equal. The main benefits that teacher mention is the expanded concept of text that offers multiple forms of expression and the authentic reader, which makes it more real, important and meaningful. Other benefits that come up are that it helps students to see their learning and learn from and with each other.

The object of this thesis is to direct attention onto female inmates who is a disregarded user group within the discipline of library and information sciences. This study has been performed on location at the Hinseberg correctional institution where nine female criminal offenders constitute the empirical foundation of our inquiry. The question proposed for solution is as follows: Is there a correlation between socio-cultural prerequisites and the reading habits of the female inmates - and if so how can it be described? Among the conclusions that we have drawn from our study is that the socio-cultural environment has an influence on the well-being of the inmates which in its turn has an impact on their reading. However, the effects on their mental state vary and consequently so does also their reading.

The objective of this research is to unveil how respective teacher consider about the laboratory working methods in mathematics. The research even includes answers to questions such as, what approaches and attitudes the teachers have and the methods they use when instructing their students when teaching mathematics, what the materials used by the teachers are and how important working creatively is to help the students develop their logical thinking. I also looked into issues that can help understand how and why teachers use laboratory mathematics for students in young ages. As a conclusion the research showed that the teachers aim to the goal that includes helping the students understand mathematics, strengthen their logical thinking and creativity.In the method section qualitative data was used, which contained four interviews with different pedagogues that daily interact with students in elementary school. The reasons for using the method of qualitative data was to help me deeper understand and answer the specific questions I had to the pedagogues and to even compare how different pedagogues differ in their approaches and methods.

The purpose of this study was to examine the experience of organizational culture among salespeople at a specific workplace. The purpose was also to investigate what motivates these salespeople in their work and the impact culture has on their motivation. We have used a qualitative research method to collect the empirical material. With the help of seven interviews, including six salespeople from one of Sweden?s biggest electronic retailer and also one information interview with a sales consultant, we attempted to find the answer to how they perceive the organizational culture and how it affects their work motivation. The following questions are used to fulfill this purpose: ? How do the salespeople experience the organizational culture? ? What motivates the salespeople in their daily work? ? What effects does the organizational culture have on the salespersons motivation? As analytical tools we have used are the concept of organizational culture, Schein's description of the three components of culture and Herzberg Motivation-Hygiene theory. The results of the study indicate that the salespeople experience a positive organizational culture and that this culture promotes fellowship and unity between colleagues, which in turn contributes to an enhanced motivation.

Syftet med denna studie är att undersöka vilka likheter och skillnader i undervisningen som finns mellan en grundsärskoleklass och en grundskoleklass. Undersökningens metod är strukturerade observationer genomförda av två observatörer i en grundskoleklass och i en särskoleklass på samma skola. Olika aspekter av undervisningen observerades, av vilka några kan anses utgöra förutsättningar för en inkluderande undervisning. Dessa är: samarbete mellan pedagoger i undervisningen, ledarskapsmodeller, cooperativt lärande (samarbetsinlärning), dynamisk pedagogik samt samarbete mellan pedagoger i problemlösande undervisning. Resultatet visar på likhet mellan de båda skolformerna beträffande användandet av en organismisk modell med ett demokratiskt ledarskap, där grundsärskolans pedagoger endast använder det aningen mer frekvent än grundskolans pedagoger.

This thesis aims towards an understanding of information systems and subject representation in relation to academic disciplines. This is achieved by comparing how a discipline, History of science and ideas, represents itself compared with the subject representation of its dissertations in an information system, LIBRIS. The point of departure for this thesis is the domain analytic view of Hjorland which states that the quality in information seeking is enhanced if the subject representation considers the contexts in which documents are produced and used. The importance of concepts such as domain and discipline is discussed. The disciplines view of itself is established by the study of articles written by scholars in the discipline, by how the discipline presents itself on the homepages of five university institutions and by the examination of titles and keywords given to dissertations in the discipline.

Human rights have been added to the new curriculum which came into force the 1st of July 2011 in the Swedish Upper Secondary school.

Further the analysis focus on what is affecting discourses in the Social Science about human rights, as well as its communication and incorporation in its education. The empirical material consists of the schools steering documents and interviews with Social Science teachers. The theoretical framework is based on human rights education (HRE) and curriculum theory.

The objective for this study was to acquire a greater insight if children with concentration difficulties are assisted by outdoor education in the traditional teaching. With the use of a qualitative methodology four teachers were interviewed. The outcome gave evidence for that the teachers thought that outdoor education has a positive outcome for children with concentrations difficulties. The findings were divided into three key categories: the teacher?s reflections about outdoor education, outdoor education for children with difficulties in concentration and if there was any difference in how the children behaved indoors after having educations outdoors..

The purpose of this paper is to examine the role of logotypes within the visual identity and identify possible reasons that motivate companies to change their logo. This paper should also clarify how different parts of the visual identity affect each other and how they are interconnected. The thesis research question is formulated with the purpose in mind and has led to the following question: How can a logo change contribute to enhanced visual identity? Since we wanted to obtain a better understanding of the chosen research area with help of interviews have we chosen a qualitative method for this thesis. During the process we have let the empirical material control the chosen theories.

The purpose of this paper is to show how practicing teachers work to prevent racism. Based on four interviews with teachers at low-, middle- and high schools, where these schools differ in numbers of immigrants and geographical location. Conclusion: None of the four teachers feel that racism is a problem at their school; however, they are confident that some racism is present at their school.
