Why do some children in the developing world choose to stay out of school? Is it mainly because poverty leaves them with no options or because schooling seems to offer them few benefits? The answers to these questions have profound policy implications. An empirical input into this discussion is the extent to which schooling can actually be perceived as a profitable option in various countries and,
In this thesis a graphical language for sequential control is presented and its application to batch control is examined and discussed. The name of the language is Grafchart. Its main feature is that it makes it possible to express complicated control problems in a compact and intuitive manner.Grafchart exists in two versions; a basic version and a high-level version. The basic version was availab
In studies concerning the youngest children, the toddlers, the gender perspective is often missing. One aim of the study was, therefore, to investigate the interaction between children and preschool teachers in day care centres in a gender and a contextual perspective. Another aim was to investigate the inner representations of the preschool teachers concerning children and gender. A third aim was
This thesis investigates structure-acoustic systems by use of finite element analysis. The systems studied here are limited to those that consist of an enclosed acoustic fluid cavity, which is coupled to a flexible structure and/or a porous sound absorbing material domain. This type of analysis is applicable to a wide range of engineering problems, for example, studying the interior noise in a ve
The general aim of the investigation is to contribute to the development of a theory of change and learning within the working environment. The specific change processes that were examined, emerged from an interactive initiative for change, intending to facilitate an emancipatory development: employees increasing their control of the work situation, thus improving the quality of service. The empir
The paper making process involves chopping of wood, cooking and forming, followed by dewatering in a vacuum section, press section and drying section. Several models for the most important parts of the paper machine drying section are presented in this thesis to describe phenomena at steady state and during state transitions. New control strategies applicable/useful for both steady-state control a
This thesis is about dynamics of piecewise hyperbolic maps on bounded sets in the plane and on the interval. It is based on the following papers: T. Persson, A piecewise hyperbolic map with absolutely continuous invariant measure, Dynamical Systems: An International Journal, 21:3 (2006), 363--378 T. Persson, Absolutely continuous invariant measures for some piecewise hyperbolic affine maps, Prep
This dissertation is a historical-comparative analysis of a conflict that has developed in the economic system of the Miskito in the 20th century, concerning the use of common property resources. The study is based on empirical material collected in a Miskito/Creole village on the Atlantic Coast of Nicaragua in the 1990s. During the enclave period (1860-1960) Miskito men earned money as wage labou
Anglo-American post-Second World War relations in the Middle East included cases of close cooperation and conflict. An example of the former was the Pentagon Talks in 1947 when an American statement pointed out the general objective of maintaining the security of the Middle East by retaining the British political, economic, and strategic position in areas supported by the United States. An example
Type 2 diabetes is a disease that increases tremendously in the western world. It is characterized by insulin resistance and defects in insulin secretion. Insulin resistance is tightly linked to obesity, and usually precedes the onset of type 2 diabetes. When insulin resistance develops, the pancreatic beta-cells compensate by in¬creasing their secretion of insulin, causing hyperinsulinemia. This
This thesis aimed to investigate visual-vestibular interactions in healthy subjects and in patients with a well defined unilateral vestibular lesion (vestibular schwannoma before and six months after translabyrinthine surgery). Visual information is particularly important for balance control during perturbed stance. The physical act of having the eyes open or closed affects motion strategy in pos
The life and history of the Hawaiians has been documented ever since the contact with Western adventurers at the end of the 18th century. In connection with the arrival of American missionaries in 1820, these missionaries introduced and established a puritanical doctrine and method of communicating knowledge by way of the written word. The encounters between the different cultures have been descri
Obesity is increasing throughout the world at an epidemic rate, partly due to increased consumption of diets rich in fat and/or sugar. Ghrelin and leptin are hormones, originating from the periphery, involved in the regulation of food intake and of maintaining energy homeostasis. Circulating ghrelin levels increase in times of energy deficiency, such as fasting, signalling hunger whereas circulati

This study is built around the following research question: "How do student nurses conceptions regarding their future profession change during their training in the three year nursing programme?" The study is longitudinal in character and consists of qualitative interviews conducted with eighteen students belonging to the same nursing class. The students were interviewed on four occasions during
Viruses have developed several strategies to evade the complement system, a part of the immune system. The fourth open reading frame of the human virus Kaposi's sarcoma-associated herpesvirus (KSHV) encodes a type 1 transmembrane protein. This contains four complement control protein domains (CCP domains), and is thus structurally similar to human complement inhibitors. We named it KSHV complement
Road profiles are studied from a vehicle fatigue point of view. A wide range of roads have been measured: from smooth motorways to very rough gravel roads. It is observed that the road profiles consist of irregular sections, which makes the stationary Gaussian model unsuitable (Paper A). In Paper B, a method for automatic identification of such irregularities is presented. It is verified that the
This volume is a new edition with a parallel English translation of eight Greek stories related to Daniel of Sketis: 1) Abba Daniel from Sketis; 2) Abba Mark the Fool; 3) The blind man; 4AB) A holy and chaste young woman; 5) The woman who pretended to be a drunkard; 6) Eulogios the Stone-cutter; 7) Andronikos the Money-dealer and his wife Athanasia; 8) Anastasia Patrikia. The stories deal with se
