The Australian Nutrition Foundation (ANF) was one of the first community service organisations to work with food industry , having pioneered the concept of corporate membership since its inception in 1982. ANF has worked closely and successfully with industry - the development of the ANF Food Selection Guidelines for Children and Adolescents is one example of this collaboration. While the guidelines were initially developed for use in school canteens, they can be used in a range of institutions where caterers wish to have tender specifications for purchase of healthy food for children and adolescents.

With the availability of a huge amount of video data on various sources, efficient video retrieval tools are increasingly in demand. Video being a multi-modal data, the perceptions of ``relevance'' between the user provided query video (in case of Query-By-Example type of video search) and retrieved video clips are subjective in nature. We present an efficient video retrieval method that takes user's feedback on the relevance of retrieved videos and iteratively reformulates the input query feature vectors (QFV) for improved video retrieval. The QFV reformulation is done by a simple, but powerful feature weight optimization method based on Simultaneous Perturbation Stochastic Approximation (SPSA) technique. A video retrieval system with video indexing, searching and relevance feedback (RF) phases is built for demonstrating the performance of the proposed method. The query and database videos are indexed using the conventional video features like color, texture, etc. However, we use the comprehensive and novel methods of feature representations, and a spatio-temporal distance measure to retrieve the top M videos that are similar to the query. In feedback phase, the user activated iterative on the previously retrieved videos is used to reformulate the QFV weights (measure of importance) that reflect the user's preference, automatically. It is our observation that a few iterations of such feedback are generally sufficient for retrieving the desired video clips. The novel application of SPSA based RF for user-oriented feature weights optimization makes the proposed method to be distinct from the existing ones. The experimental results show that the proposed RF based video retrieval exhibit good performance.

Let E be an elliptic curve defined over Q and let K/Q be a finite Galois extension with Galois group G. The equivariant Birch-Swinnerton-Dyer conjecture for h(1)(E x(Q) K)(1) viewed as amotive over Q with coefficients in Q[G] relates the twisted L-values associated with E with the arithmetic invariants of the same. In this paper I prescribe an approach to verify this conjecture for a given data. Using this approach, we verify the conjecture for an elliptic curve of conductor 11 and an S-3-extension of Q.

The dissertation "From Conceptual to Corporeal, from Quotation to Site: Painting and History of Contemporary Art" explores the state of painting in contemporary art and art theory since the 1960s. The purpose of the study is to re-consider the dominant "end of painting" -narrative in contemporary art history, which goes back to the modernist ideology of painting as a reductive, medium-specific form of art. Drawing on Michel Foucault´s concepts of discursive formation and archive, as well as Jean-Luc Nancy´s post-phenomenological philosophy on corporeality, I suggest that contemporary painting can be redefined as a discursive-sensuous practice. Instead of seeing painting as obsolete or over as an avantgarde art genre, I show that there have been alternative, neo-avantgardist ways of defining painting since the end of the 1960s, such as French artist Daniel Buren´s early writings on painting as "theoretical practice". Consequently, the tendency of the canonical Anglo-American contemporary art narratives to underestimate the historical and institutional codes of art can be questioned. This tendency can be seen, for example, in Rosalind Krauss´s influential theory on index. The study also reflects the relations between conceptual art and painting since the 1960s and maps recent theories of painting, which re-examine the genre´s possibilities after the modernist rhetoric. Concepts of "flatbed", "painting in the extended field", "as painting" and so on are compared critically with the idea of painting as discursive practice. It is also shown that the issues in painting arise from the contemporary critical art debate while the dematerialisation paradigm of conceptual art has dissolved. The study focuses on the corporeal-material-sensuous -cluster of meanings attached to painting and searches for its avantgardist possibilities as redefined by postfeminist and post-phenomenological discourse. The ideas of hierarchy of the senses and synesthesia are developed within the framework of Jean-Luc Nancy´s and Luce Irigaray´s thought. The parameters for the study have been Finnish painting from 1990 to 2002. On the Finnish art scene there has been no "end of painting" ideology, strictly speaking. The mythology and medium-specificity of modernism have been deconstructed since the mid-1980s, but "the archive" of painting, like themes of abstraction, formalism and synesthesia have been re-worked by the discursive practice of painting, for example, in the works of Nina Roos, Tarja Pitkänen-Walter and Jussi Niva.

The dissertation presents a functional model for analysis of song translation. The model is developed on the basis of an examination of theatrical songs and a comparison of three translations: the songs of the Broadway musical My Fair Lady (Lerner and Loewe, 1956), made for the premiere productions (1959–1960) in Swedish, Danish, and Norwegian. The analysis explores the three challenges of a song translator: the fitting of a text to existing music, the consideration of a prospective sung performance, and the verbal approximation of the content of the source lyric. The theoretical foundation is based on a functional approach to translation studies (Christiane Nord) and a structuralist/semiotic analysis of a theatrical message (Ivo Osolsobě, building on Roman Jakobson). Thus, three functional levels in the fitting of a text to music are explored: first, a prosodic/phonetic format; secondly, a poetic/rhetoric format; and thirdly, semantic/reflexive values (verbalizing musical expression). Similarly, three functional levels in the textual connections to a prospective performance are explored: first, a presentational goal; secondly, the theatrical potential; and thirdly, dramaturgic values (for example dramatic information and linguistic register). The functionality of Broadway musical theatre songs is analyzed, and the song score of My Fair Lady, source and target lyrics, is studied, with an in-depth analysis of seven of the songs. The three translations were all considered very well-made and are used in productions of the musical to this day. The study finds that the song translators appear to have worked from an understanding of the presentational goal, designed their target texts on the prosodic and poetic shape of the music, and pursued the theatrical functionality of the song, not by copying, but by recreating connections to relevant contexts, partly independently of the source lyrics, using the resources of the target languages. Besides metaphrases (closest possible transfer), paraphrases and additions seem normally to be expected in song translation, but song translators may also follow highly individual strategies – for example, the Norwegian translator is consistently more verbally faithful than the Danish and Swedish translators. As a conclusion, it is suggested that although linguistic and cultural difference play a significant role, a translator’s solution must nevertheless be arrived at, and assessed, in relation to the song as a multimedial piece of material. As far as a song can be considered a theatrical message – singers representing the voice, person, and situation of the song – the descriptive model presented in the study is also applicable to the translation of other types of song.

The study concentrated on interdisciplinary teamwork of students in Helsinki University Department of Education and Helsinki University of Technology. Students worked in small interdisciplinary groups (n 12) to plan and teach in an information- and communication technology (ICT) club in elementary schools. The focus of the study was co-operation in the student groups and students learning experiences. Theoretical background of the study consists of theories of collaboration and socially shared cognition. Study was an qualitative case study and the data was collected with individual focus interviews and learning diaries. The data was categorised and the connections between categories were analysed with a table. Shared cognition appeared as a form of distribution of tasks and in the actual processes of shared expertise. The tasks were shared according to students expertise. Processes of shared expertise were joint knowledge building, integration of interests, awareness and exploitation of others expertise and allowing freedom for others to use their expertise. Additionally expression of ones own views and setting an example to others were one sided sharing of expertise. Students of technology were responsible of technical issues and the responsibility sphere of educational science students was more fragmented. For instance they concentrated in taking children s abilities into consideration. The sphere of shared cognition included also the need for tutoring and learning from others. Usually students did not directly learn from representative of other discipline, instead the learning for instance of social skills happened indirectly. Learning was fostered if learning was set as a goal and prevented if the differences in expertise were too minor. Sharing of cognition was prevented if co-operation was too problematic. Co-operation was usually successful. Good planning, good person chemistry and appreciation of expertise of others promoted success. Problems caused by different backgrounds were usually slight. Successful interaction was complementary and equal. Groups were usually able to circumvent problems in communication and use of justification in discussion promoted co-operation. When comparing the groups in the scope of the study, two were found to be notably opposed and the other groups located between these extreme cases, but the elements of success prevailed. Learning experiences concentrated on social skills, project management, school world and ICT. Essential was achieved field experience and observation of ones own capabilities. In organisation of student interdisciplinary co-operation is important to ensure sufficient differences in expertise and guide students to gain complementary interaction and appropriate setting of goals. Interdisciplinary field project prepared students to face the demands of

This dissertation examined the research-based teacher education at the University of Helsinki from different theoretical and practical perspectives. Five studies focused on these perspectives separately as well as overlappingly. Study I focused on the reflection process of graduating teacher students. The data consisted of essays the students wrote as their last assignment before graduating, where their assignment was to examine their development as researchers during their MA thesis research process. The results indicated that the teacher students had analysed their own development thoroughly during the process and that they had reflected on theoretical as well as practical educational matters. The results also pointed out that, in the students’ opinion, personally conducted research is a significant learning process. -- Study II investigated teacher students’ workplace learning and the integration of theory and practice in teacher education. The students’ interviews focused on their learning of teacher’s work prior to education. The interviewees’ responses concerning their ‘surviving’ in teaching prior to teacher education were categorized into three categories: learning through experiences, school as a teacher learning environment, and case-specific learning. The survey part of the study focused on integration of theory and practice within the education process. The results showed that the students who worked while they studied took advantage of the studies and applied them to work. They set more demanding teaching goals and reflected on their work more theoretically. -- Study III examined practical aspects of the teacher students’ MA thesis research as well as the integration of theory and practice in teacher education. The participants were surveyed using a web-based survey which dealt with the participants’ teacher education experiences. According to the results, most of the students had chosen a practical topic for their MA thesis, one arising from their work environment, and most had chosen a research topic that would develop their own teaching. The results showed that the integration of theory and practice had taken place in much of the course work, but most obviously in the practicum periods, and also in the courses concerning the school subjects. The majority felt that the education had in some way been successful with regards to integration. -- Study IV explored the idea of considering teacher students’ MA thesis research as professional development. Twenty-three teachers were interviewed on the subject of their experiences of conducting research about their own work as teachers. The results of the interviews showed that the reasons for choosing the MA thesis research topic were multiple: practical, theoretical, personal, professional reasons, as well as outside effect. The objectives of the MA thesis research, besides graduating, were actual projects, developing the ability to work as teachers, conducting significant research, and sharing knowledge of the topic. The results indicated that an MA thesis can function as a tool for professional development, for example in finding ways for adjusting teaching, increasing interaction skills, gaining knowledge or improving reflection on theory and/or practice, strengthening self-confidence as a teacher, increasing researching skills or academic writing skills, as well as becoming critical and being able to read scientific and academic literature. -- Study V analysed teachers’ views of the impact of practitioner research. According to the results, the interviewees considered the benefits of practitioner research to be many, affecting teachers, pupils, parents, the working community, and the wider society. Most of the teachers indicated that they intended to continue to conduct research in the future. The results also showed that teachers often reflected personally and collectively, and viewed this as important. -- These five studies point out that MA thesis research is and can be a useful tool for increasing reflection doing with personal and professional development, as well as integrating theory and practice. The studies suggest that more advantage could be taken of the MA thesis research project. More integration of working and studying could and should be made possible for teacher students. This could be done in various ways within teacher education, but the MA thesis should be seen as a pedagogical possibility.

When Finland occupied East Karelian territories in Soviet Union during The Continuation War (1941 1944) Finnish people had also to take care of the inhabitants of the occupied East Karelia. For example there was a lack of clothes and shoes during the wartime. In order to facilitate clothing situation and to provide more opportunities to work for women, Finnish people founded some workshops in East Karelia. Workshops also helped to collect East Karelian craft products. One of the workshops was founded in the city of Olonets in October 1941 and it was in operation until June 1944. This workshop is the subject of this thesis. The aim of this thesis is to find out with the microhistorical approach what kind of functions the workshop of Olonets had during The Continuation War and who worked in the workshop. In this thesis I also examine women s crafts in the Olonets workshop and their meaning during the wartime. I collected the material of this thesis from different places. In February 2010 I interviewed Talvikki Lausala, the leader of the Olonets workshop, who worked in the Olonets from May 1942 to June 1944. From the Virkki Käsityömuseo I looked for objects which have been made in the workshop of Olonets. Tyyne-Kerttu Virkki collected crafts from the East Karelia when she was working in the area and in the workshop from 1941 to 1944. Archive material I found from the Finnish National archive and from the archive of the Tyyne-Kerttu Virkki -Foundation. East Karelian women and girls who were not able to do anything else came to work in the Olonets workshop. If women could not go to work outside of home, they had an option to do the same crafts at home. There were three Finnish women, Tyyne-Kerttu Virkki, Talvikki Lausala and Sofi Nyrkkö, who worked and led in the workshop of Olonets. In addition to the workshop, there was a dress maker s atelier in which clothes were made to order and soldiers uniforms were repaired, a small museum and a shop to sell products of the workshop. Craft products were also exported to Finland. Courses were organized in which Finnish women taught East Karelian crafts.

All sound research commence with the selection of a research paradigm. The chosen research paradigm is significant in shaping the researcher’s perspectives of the world and it is a vital step in any study’s’ research design. There are different paradigms that IS researchers can choose from; amongst which the interpretive paradigm is growing in acceptance.. Though interpretive research has emerged as an important strand in Information Systems (IS), guidelines on how to conduct interpretive research and how to evaluate them have been scarce. Klein and Myers presented seven principles with examples for each from three case examples. While these principles are much valued, there is a lack of support for novice researchers on how to embed these principles in an overall research design, which could help with the aid of a detailed example that has done so. Thus, this paper aims to address this gap, and presents how Klein and Myers’s principles were applied within an example study that investigated shared services in the Malaysian Higher Education context. The example study adopted the interpretive paradigm as the most suited approach that fitted their research questions and goals. More details about the selection and adoption of the Klein and Myers’s guidelines in the context of the shared services research case study are presented in the paper.

This paper examines the idea that plasticity in farm management introduces resilience to change and allows farm businesses to perform when operating in highly variable environments. We also argue for the need to develop and apply more integrative assessments of farm performance that combine the use of modelling tools with deliberative processes involving farmers and researchers in a co-learning process, to more effectively identify and implement more productive and resilient farm businesses. In a plastic farming system, farm management is highly contingent on environmental conditions. In plastic farming systems farm managers constantly vary crops and inputs based on the availability of limited and variable resources (e.g. land, water, finances, labour, machinery, etc.), and signals from its operating environment (e.g. climate, markets), with the objective of maximising a number of, often competing, objectives (e.g. maximise profits, minimise risks, etc.). In contrast in more rigid farming systems farm management is more calendar driven and relatively fixed sequences of crops are regularly followed over time and across the farm. Here we describe the application of a whole farm simulation model to (i) compare, in silico, the sensitivity of two farming systems designs of contrasting levels of plasticity, operating in two contrasting environments, when exposed to a stressor in the form of climate change scenarios;(ii) investigate the presence of interactions and feedbacks at the field and farm levels capable of modifying the intensity and direction of the responses to climate signals; and (iii) discuss the need for the development and application of more integrative assessments in the analysis of impacts and adaptation options to climate change. In both environments, the more plastic farm management strategy had higher median profits and was less risky for the baseline and less intensive climate change scenarios (2030). However, for the more severe climate change scenarios (2070), the benefit of plastic strategies tended to disappear. These results suggest that, to a point, farming systems having higher levels of plasticity would enable farmers to more effectively respond to climate shifts, thus ensuring the economic viability of the farm business. Though, as the intensity of the stress increases (e.g. 2070 climate change scenario) more significant changes in the farming system might be required to adapt. We also found that in the case studies analysed here, most of the impacts from the climate change scenarios on farm profit and economic risk originated from important reductions in cropping intensity and changes in crop mix rather than from changes in the yields of individual crops. Changes in cropping intensity and crop mix were explained by the combination of reductions in the number of sowing opportunities around critical times in the cropping calendar, and to operational constraints at the whole farm level i.e. limited work capacity in an environment having fewer and more concentrated sowing opportunities. This indicates that indirect impacts from shifts in climate on farm operations can be more important than direct impacts from climate on the yield of individual crops. The results suggest that due to the complexity of farm businesses, impact assessments and opportunities for adaptation to climate change might also need to be pursued at higher integration levels than the crop or the field. We conclude that plasticity can be a desirable characteristic in farming systems operating in highly variable environments, and that integrated whole farm systems analyses of impacts and adaptation to climate change are required to identify important interactions between farm management decision rules, availability of resources, and farmer's preference.

A holistic approach to stock structure studies utilises multiple different techniques on the same individuals sampled from selected populations and combines results across spatial and temporal scales to produce a weight of evidence conclusion. It is the most powerful and reliable source of information to use in formulating resource management and monitoring plans. Few examples of the use of a holistic approach in stock structure studies exist, although more recently this is changing. Using such an approach makes integration of results from each technique challenging. An integrated stock definition (ISD) approach for holistic stock structure studies was developed in this study to aid in the appropriate interpretation of stock structure results to guide the determination of fishery management units. The ISD approach is applied herein to a study of the northern Australian endemic grey mackerel, Scomberomorus semifasciatus (Scombridae). Analyses of genetic (mitochondrial DNA and microsatellites), parasite, otolith stable isotope, and growth data are synthesised to determine the stock structure of S. semifasciatus across northern Australia. Integration of the results from all techniques identified at least six S. semifasciatus stocks for management purposes. Further, the use of the ISD approach provided a simple basis for integrating multiple techniques and for their interpretation. The use of this holistic approach was a powerful tool in providing greater certainty about the appropriate management units for S. semifasciatus. Future stock structure studies investigating spatial management questions in the fisheries context should adopt a holistic approach and apply the ISD approach for a more accurate definition of biological stocks to improve fisheries management.

Sangen ialo Rucous. The prayer book of the Schwenckfeldiens as a source for Michael Agricola The significance of the prayer book published by the Finnish reformer Michael Agricola in the year of 1544 has not been comprehended enough among the prayer literature of the Reformation century. Especially in foreign research literature one of the era s most extensive and versatile prayer books has been practically disregarded. According to the prayer book, Agricola appears to be a traditionalist, who derives most of his source material from medieval and old church prayer books. The low number of the prayers from Evangelical prayer books is noteworthy. The study in hand examines Agricola s theology expressed in his translation work of the prayer book of the mystic spiritualistic Schwenckfeldien movement. The prayer book of the Schwenckdeldiens diverged from Lutheranism was called Bekantnus der sünden and it was composed around the year of 1526. Agricola is the only prayer book collector who has regarded it as necessary to add all the 45 prayers of the Schwenckfeldien prayer book and its introduction to his book. In the prayers containing the Schwenckfeldien communion theology and Christology Agricola has not changed the content of the text, apparently because he was not aware of the problems involved in the Schwenckfeldien theology. On a few occasions Agricola added points of view concerning the church, priesthood, preaching the Word and sacraments to his prayers, which the Schwenckfeldiens despised. From the ten additions four Agricola created himself, the rest he borrowed from Wolfgang Capito s prayer book. As a source Agricola used Capito s Latin prayer book together with the German text from Bekantnus. When looking at the studied material, Agricola does not turn out to be a creative translator. Even though he had a model for a less restricted translation in Wolfgang Capito s prayer book, he sticks to his habit of translating word by word. Because not even a good example has had a liberating effect on his translation principles, Agricola cannot be considered a theologically orientated writer. The translation of the Schwenckfeldien prayers Agricola starts with Capito s prayer book. Very soon he takes the Bekantnus alongside Capito s text and abandons the use of Capito s prayer book in the middle of the translation process. Comparing Agricola s translation with the two texts in different languages has made it possible to create the disposition theory described above. On the basis of the disposition theory it can be concluded that Agricola first worked out a precise plan for his prayer book. Then he translated prayers theme by theme using multiple sources at the same time. Later Agricola fixed the disposition, which does not seem to have a direct paragon. From the prayers of the Schwenckfeldien prayer book Agricola translated 26 texts using the Bekantnus as an only base, from Capito s prayer book he translated four texts and 17 texts he translated using the two basic texts simultaneously. In the previous studies, words and texts added by Agricola have been examined as one problem unit. In this study the additions have been placed into three different categories: additions consequential on tautological parataxis, specifying additions and additions significant to the content. Due to Agricola s meticulous translation techniques, there are so few additions. Agricola does not show his own creativity even in the additions significant to the content but uses there some complete sentences or word fragments from the other prayers he has translated. In the translations of the prayers there are some unique appearing words and the analysis of the translation work shed a new light on the background of their first literary appearance in Finnish. Agricola s linguistic abilities turned out to be great. In those prayers where Agricola uses both the German and Latin basic texts at the same time, the translation process is a very intensive twine made on the basis of the two sources.

Understanding the important concepts necessary to undertake the preparation of consolidated financial statements has proven challenging for many accounting undergraduate students. As a result, the development of multimedia modelling concepts such as acquisition analysis, business combination valuation entries, reacquisition entries and intragroup transactions were embedded within an e-learning environment. The principle of modelling, derived from social cognitive theory, was applied to the design of the multimedia. A study was conducted to gauge the effectiveness of the approach and consider student perceptions with regard to learning through this approach. Quantitative data were collected from accounting undergraduate students (n= 464) enrolled across three different cohorts including international campuses (n=386), an Australian campus (n=49) and a distance education cohort (n=29). Analyses were undertaken to show significant differences between these cohorts. This research paper presents findings that indicate a positive and significant association between the number of times the videos were accessed, and the assignment score (p<0.05) was evident, suggesting that students that referred to the videos relatively frequently were able to utilise the knowledge gained from the videos to assist them in completing the assignment.

A ternary metal complex involving Vitamin B6 with the formula [Cu(bipy)(pn) (OH)]H2O (bipy = 2,2'²-bipyridine, PN = anionic pyridoxine) has been synthesized and studied in the solid state by means of spectroscopy and X-ray crystallography. The geometry around copper(II) is distorted square pyramidal, two oxygens from phenolic and 4-(hydroxymethyl) groups of pn, two nitrogens from bipy and an axial OH- ion forming the coordination sphere. In this structure pn exists in a new anionic form with deprotonation of the phenolic group. The structure also provides a rare example of monodentate hydroxyl coordination to copper.
