Fruktkvalitet inom äppelodlingen : en studie av och för Äppelriket Österlen

The main purpose of this Master Thesis has been to investigate issues concerning apple fruit quality in orchards of Äppelriket Österlen. The goal has been to develop a document, for future benefit towards growers and company management in the production of high quality apples.In order to investigate main issues of fruit quality, focus has been on statistics concerning apple varieties, age of the apple trees, new planting, orchard size and growers opinions. Nine growers have been interviewed to investigate opinions and contribution of different growing techniques to increased fruit quality. The investigation showed high age of the trees in production and low rate of planting of new trees. Differences in fruit quality were highest between small orchards. Most growers were satisfied with their fruit quality and with their own measures made to improve it.

Att arbeta enligt BBIC : En kvalitativ studie om socialsekreterares upplevelser av att arbeta enligt BBIC - Barns Behov i Centrum

Children's Need In Focus (BBIC) is a processing and documentation system used in child welfare cases to investigate, plan and monitor interventions. The BBIC has had a breakthrough in Sweden and out of the country's 290 municipalities, there are 284 that use the system daily as a tool in cases involving children. The purpose of this study was to examine how social workers experience the BBIC as a working system and what strengths and weaknesses there are in the BBIC concept. We wanted our study to examine how the BBIC could possibly enhance the quality of childcare matters, but also how the BBIC could potentially increase children's participation in cases. We have performed qualitative interviews with eight social workers who work in four different municipalities where the BBIC is applied daily.

Apportegendom i form av arbete och tjänst? : Ur ett borgenärs- och värderingsperspektiv

The enormous expansion of knowledge society has lead to a path away from the industrial enterprises toward the more knowledge-based entrepreneurship companies. This development has also meant that intellectual capital now can be seen as the core of the new business structure. However the growth has not been reflected in either the legal or the economic regulations in relation to what could have been expected, which means that there is thus a gap between de lege lata and de lege ferenda. This can specifically been seen regarding the prohibition of adding property other than cash applied in payment for shares or regarding issue of new shares when it comes to work and services. The prohibition may therefore be considered to stand against the knowledge companies? advancement.

Kravhantering ? Brister och lösningar

 SammanfattningKravhanteringsprocessen är en av de viktigaste faserna vid utvecklandet av ett IT-system. Kravhantering är alltså grundläggande för att utveckla ett stabilt system som uppfyller beställarens önskemål. Med en väl utförd kravhantering som grund får man ett system som är fritt från bristfälliga fel, utvecklandet av systemet går även till på ett effektivare sätt. Vid byggandet av ett system eftersträvar man alltid en framgångsrik mjukvara. Kravhantering ses som den viktigaste faktorn vid utvecklandet av ett IT-system.Föreliggande studie genomförs som en litteraturstudie där undersöks vilka brister som är vanligt förekommande under kravhanteringsprocessen.

Tillämpning av Unified Process och Design Patterns vid integrering av system

The computer consultant company Create in Lund AB wishes to facilitate their invoice routines, as it at present is required that the administration finds and compares information from two different systems.The purpose of this thesis is to develop an invoice management system that simplifies the invoice management process for the administration at Create. During the development of the system, I have chosen to follow the software development process Unified Process and also tried to find design patterns that can be applied to the integration.The result of my project is a self-contained application developed using the Java programming language that communicates with the databases of the other two systems and presents relevant information to the user as a set of invoices. Of the 23 design patterns I studied, I used four of them in the invoice management system. However I couldn?t find any connection between any design pattern and the integration of systems.

African swine fever in Uganda : attitudes and possible interventions to limit the spread of the disease

The objective of this study was to investigate the attitude towards African swine fever (ASF) primarily among smallholder pig farmers but also among other actors along the pork value chain in Gulu district, Uganda. More specifically, the study aimed to investigate the specific challenges facing both farmers and other members of the pork value chain using participatory epidemiology (PE). ASF is a feared viral disease of pigs associated with high mortality, which is endemic in many parts of Africa. The recent history of Gulu district in Northern Uganda can be described as turbulent and the human population has suffered during decades of war and civil unrest. Pig keeping is considered a potential opportunity for business as well as a way of providing more animal protein in the diet. However, this is threatened by ASF as farmers can lose entire herds due to the disease. This study can confirm some previously known factors and risk activities such as the free range system of pigs and movement of pigs and pork during ongoing outbreaks, which make disease control difficult.

Kvalitetsledningssystem enligt ISO 9001 : Produktionsprocessen

This report is the result of a thesis work done at the Department of Engineering Sciences, Uppsala University, and includes 15 ECTS points. The work has been performed at Företag A, a company specializing in electronics whose major product has become a sophisticated tool used by authorities across northern Europe. Företag A has initiated a quality management system according to the criteria set by ISO 9001. Following demands from customers, Company A has now decided to also start working towards a certification according to SS-EN ISO 9001:2008, this work is the foundation for the thesis work. The thesis work has been limited to the production process and the aim has been to enable this process to be certified according to ISO 9001:2008. The work has been performed by analyzing the existing quality management system and the requirements for each process included, whereby the gap between the current and the target state has been mapped. Suggestions have then been made on how this gap can be filled, some of these suggestions have also been carried out during the thesis work. The conclusions drawn are that quality management does not have to be complicated, but quickly becomes so when the complexity of the processes increases.

Spelifiering : En fallstudie med fokus på framställning och slutgiltigt värde

This bachelor thesis is an exploratory investigation about the phenomenon 'Gamification', which by some definitions is about implementing game elements into non-game contexts. For example exercise services as Runkeeper and Nike Plus who both are available on android and iOS platforms. This study is mainly about the potential value of gamified systems and services for companies and its users and how such a system or service is developed. The thesis also discusses the development aspect of gamified systems in order to give the reader a more ?in depth? understanding about the phenomenon.

För kunskaps skull? : En kvalitativ intervjuundersökning med sex bibliotekarier på folkbibliotek om läsning och förmedling av skönlitteratur.

The aim of this master's thesis is to examine whether librarians working in public libraries see fiction as a source of knowledge, and what role this plays in the educational mission of the public library. This investigation, which consists of a literary study and an empirical section, shows that the concept of phronesis denotes practical wisdom and moral thinking, and that it can be applied to that form of knowledge to which reading can contribute. An important issue in this context is the reader's motivation to learn. The interviews show that librarians see literature as a source from which knowledge can be drawn. When they mediate literature, they believe that they are conveying something of value and they set great store in mediating literature which could have a not inconsiderable import to the borrowers.

Kapitalförluster vid förbud mot uppbundet system för mjölkkor

Idag finns det 5200 mjölkföretag i Sverige varav 69 procent tillämpar ett uppbundet system. Regeringen föreslår att Jordbruksverket bestämmer ett slutdatum för mjölkproduktion i uppbundet system. Målet är att förbättra djurvälfärden för nötkreatur. För den enskilde lantbrukaren innebär ett förbud mot uppbundet system ett vägval mellan att avveckla eller investera i mjölkproduktionen. Vid ett stoppdatum för uppbundet system kan det uppstå kapitalförluster för de mjölkproducenter som tvingas avveckla i form av en minskad arbets- och kapitalinkomst.
