The politics of multicultural encounters : feminist postcolonial perspectives

Det mångkulturella diskuteras livligt i den offentliga debatten idag. För att utveckla diskussionen är det viktigt att ta reda på vad som stöder bra mångkulturalism och vilka förutsättningar som finns för det mångkulturella i dagens Finland. Dessa frågor analyseras i Salla Tuoris doktorsavhandling "The politics of multicultural encounters. Feminist postcolonial perspectives." Avhandlingen behandlar hur det mångkulturella skapas i det så kallade "projektsamhället", det vill säga ett samhälle där en stor del av arbete organiseras i projekt. Studien baserar sig på fältarbete inom ett EU-finansierat sysselsättningsprojekt för invandrade kvinnor som pågick under 2002-2006 (och en bredare kontext av mångkulturellt arbete). Boken för en dialogen mellan feministiska postkoloniala analyser och vardagslivspolitiken. Studien belyser rasismens förekomst i Finland. Rasismen beskrivs ofta som baksidan av det mångkulturella, och den förknippas intimt med den invandring som skett sedan 1990-talet. Men rasism borde förstås som ett bredare fenomen, menar Tuori, det är mera än en medveten ideologi eller ett avsiktligt motiv. Arbetslivets diskriminerande strukturer samt sådan praxis i skolor, på arbetsplatser eller i grannskapet som leder till ojämställdhet, är också rasism. Det är viktigt att granska också hur expertis skapas inom det mångkulturella. Ett av studiens centrala bidrag är att lyssna på invandrares kunskap. I den etnografiska analysen framkommer att de invandrades kunskap inte alltid hörs, eller så uppfattas det inte som allmängiltig kunskap, utan som enskilda erfarenheter. Att inte lyssna kan leda till ojämställda praxis, utan att det nödvändigtvis innehåller en avsiktlig tanke att diskriminera. Studiet behandlar också möjligheter och betydelser av "empowerment" (bemäktigande, deltagande) i ett sysselsättningsprojekt. "Empowerment" förstås oftast som förstärkning av individers, ibland också gruppers, egen handlingsförmåga vilket leder till ökat handlingsutrymme. Begreppet används också inom socialpolitik och pedagogik. Som bäst fungerar "empowerment" som en kombination av förändrade yttre maktförhållanden och ökad personlig förmåga och då kan det vara ett verktyg för att stärka det mångkulturella samhället. Avhandlingen bidrar dessutom med ny kunskap om "projektsamhället" ur det enskilda projektets perspektiv. Det mångkulturella arbetet i Finland organiseras framförallt som projekt, vilket skapar strama tyglar för arbetet. Projekten ska svara mot det som finansiären anser vara viktiga tyngdpunkter och bearbeta sitt eget arbete därefter. Projektarbete innebär också ständiga rapporter, utvärderingar och "mainstreaming", vilket innebär att det administrativa får en förhållandevis stor roll i projekten. I det mångkulturella arbetet innebär detta att sysselsättningseffekten av själva projekten riktas framförallt till dem som arbetar med förvaltningen och inte de som arbetar med projektens huvudmål eller i själva projekten - och som oftast är finländare av finsk bakgrund.

Exiles and Constituents: Baltic Refugees and American Cold War Politics, 1948- 1960

This dissertation explores the complicated relations between Estonian, Latvian, and Lithuanian postwar refugees and American foreign policymakers between 1948 and 1960. There were seemingly shared interests between the parties during the first decade of the Cold War. Generally, Eastern European refugees refused to recognize Soviet hegemony in their homelands, and American policy towards the Soviet bloc during the Truman and Eisenhower administrations sought to undermine the Kremlin’s standing in the region. More specifically, Baltic refugees and State Department officials sought to preserve the 1940 non-recognition policy towards the Soviet annexation of the Baltic States. I propose that despite the seemingly natural convergence of interests, the American experiment of constructing a State-Private network revolving around fostering relations with exile groups was fraught with difficulties. These difficulties ultimately undermined any ability that the United States might have had to liberate the Baltic States from the Soviet Union. As this dissertation demonstrates, Baltic exiles were primarily concerned with preserving a high level of political continuity to the interwar republics under the assumption that they would be able to regain their positions in liberated, democratic societies. American policymakers, however, were primarily concerned with maintaining the non-recognition policy, the framework in which all policy considerations were analyzed. I argue that these two motivating factors created unnecessary tensions in American policy towards the Baltic republics in the spheres of psychological warfare as well as exile unity in the United States and Europe. Despite these shortcomings, I argue that out of the exiles’ failings was born a generation of Baltic constituents that blurred the political legitimacy line between exiles who sought to return home and ethnic Americans who were loyal to the United States. These Baltic constituents played an important role in garnering the support of the United States Congress, starting in the 1950s, but became increasingly influential after the 1956 Hungarian Revolution, despite the seemingly less important role Eastern Europe played in the Cold War. The actions of the Baltic constituents not only prevented the Baltic question from being forever lost in the memory hole of history, but actually created enough political pressure on the State Department that it was impossible to alter the long-standing policy of not recognizing the Soviet annexation of the Baltic States.

Astringent Food Compounds and Their Interactions with Taste Properties

Astringency is traditionally thought to be induced by plant tannins in foods. Because of this current research concerning the mechanism of astringency is focused on tannin‐protein interactions and thus on precipitation, which may be perceived by mechanoreceptors. However, astringency is elicited by a wide range of different phenolic compounds, as well as, some non‐phenolic compounds in various foods. Many ellagitannins or smaller compounds that contribute to astringent properties do not interact with salivary proteins and may be directly perceived through some receptors. Generally, the higher degree of polymerization of proanthocyanidins can be associated with more intense astringency. However, the astringent properties of smaller phenolic compounds may not be directly predicted from the structure of a compound, although glycosylation has a significant role. The astringency of organic acids may be directly linked to the perception of sourness, and this increases along with decreasing pH. Astringency can be divided into different sub‐qualities, including even other qualities than traditional mouth‐drying, puckering or roughing sensations. Astringency is often accompanied by bitter or sour or both taste properties. The different sub‐qualities can be influenced by different astringent compounds. In general, the glycolysation of the phenolic compound results in more velvety and smooth mouthdrying astringency. Flavonol glycosides and other flavonoid compounds and ellagitannins contribute to this velvety mouthdrying astringency. Additionally, they often lack the bitter properties. Proanthocyanidins and phenolic acids elicit more puckering and roughing astringency with some additional bitter properties. Quercetin 3‐O‐rutinoside, along with other quercetin glycosides, is among the key astringent compounds in black tea and red currants. In foods, there are always various other additional attributes that are perceived at the same with astringency. Astringent compounds themselves may have other sensory characteristics, such as bitter or sour properties, or they may enhance or suppress other sensory properties. Components contributing to these other properties, such as sugars, may also have similar effects on astringent sensations. Food components eliciting sweetness or fattiness or some polymeric polysaccharides can be used to mask astringent subqualities. Astringency can generally be referred to as a negative contributor to the liking of various foods. On the other hand, perceptions of astringent properties can vary among individuals. Many genetic factors that influence perceptions of taste properties, such as variations in perceiving a bitter taste or variations in saliva, may also effect the perception of astringency. Individuals who are more sensitive to different sensations may notice the differences between astringent properties more clearly. This may not have effects on the overall perception of astringency. However, in many cases, the liking of astringent foods may need to be learned by repetitive exposure. Astringency is often among the key sensory properties forming the unique overall flavour of certain foods, and therefore it also influences whether or not a food is liked. In many cases, astringency may be an important sub‐property suppressed by other more abundant sensory properties, but it may still have a significant contribution to the overall flavour and thus consumer preferences. The results of the practical work of this thesis show that the astringent phenolic compounds are mostly located in the skin fractions of black currants, crowberries and bilberries (publications I–III). The skin fractions themselves are rather tasteless. However, the astringent phenolic compounds can be efficiently removed from these skin fractions by consecutive ethanol extractions. Berries contain a wide range of different flavonol glycosides, hydroxycinnamic acid derivatives and anthocyanins and some of them strongly contribute to the different astringent and bitterness properties. Sweetness and sourness are located in the juice fractions along with the majority of sugars and fruit acids. The sweet and sour properties of the juice may be used to mask the astringent and bitterness properties of the extracts. Enzymatic treatments increase the astringent properties and fermented flavour of the black currant juice and decrease sweetness and freshness due to the effects on chemical compositions (IV). Sourness and sweetness are positive contributors to the liking of crowberry and bilberry fractions, whereas bitterness is more negative (V). Some astringent properties in berries are clearly negative factors, whereas some may be more positive. The liking of berries is strongly influenced by various consumer background factors, such as motives and health concerns. The liking of berries and berry fractions may also be affected by genetic factors, such as variations in the gene hTAS2R38, which codes bitter taste receptors (V).

Rural Food System Change in Tanzania during the Post-Ujamaa Era. A Case Study from Western Bagamoyo District

Food systems in Sub-Saharan Africa have been rapidly transforming during the recent decades with diverse outcomes on human development and environment. This study explores the food system change in rural villages in eastern Tanzania where subsistence agriculture has traditionally been the main source of livelihood. The focus is on the salient changes in the spatial dimensions and structural composition of the food system in the context of economic liberalization that has taken place after the end of the socialist ujamaa era in the mid-1980s. In addition, the linkages of the changes are examined in relation to food security, socio-economic situation, livelihoods, and local environment. The approach of the study is geographical, but also involves various multi-disciplinary elements, particularly from development studies. The research methods included thematic and questionnaire interviews, participatory tools, and the analysis of land use/ cover data and official documents. Several earlier studies that were made in the area during the late 1970s and 1980s provided an important reference base. The study shows that subsistence farming has lost its dominant role in food provisioning due to the declining productivity of land, livestock losses, and the increasing shift of labour to non-farm sectors. Also rapid population growth has added to the pressure on land and other natural resources. Despite the increasing need for money for buying marketed foods and other necessities, the nutritional situation shows improvement and severe malnutrition has diminished. However, the long-term sustainability of this transformation raises concerns. Firstly, the food security situation continues to be fragile and prone to shocks such as adverse climatic conditions, crop failures and price hikes. Secondly, the commodification of the food system and livelihoods in general is linked to rapid environmental degradation in the area, particularly the loss of soil fertility and deforestation. The situation calls for efforts that take more determined and holistic approaches towards sustainable development of the rural food system with particular focus on the role and viability of small-scale farming.

Packaging inks for folding cartons used in food packaging

This thesis examined packaging inks suitable for folding cartons used in food packaging. The recent cases of compounds migrating from packaging inks into packed food, have forced the packaging ink manufacturers to develop inks that do not include substances at a level, that may pose a risk to the health of a consumer or to the quality of packed food. Food packaging is a sensitive area and subject to extensive legislation. This research presents the current situation on regulatory documents that can be used to demonstrate the safety of packaging inks used in food packaging. In the research, data was also collected on the available packaging inks for food packaging in packaging ink market. Test printing was performed with five printing inks and three varnishes on Ensocoat board, produced by Stora Enso. Tests results regarding print quality, runnability, sensory properties and migration were analysed. The packaging inks with the finest performance in the tests were ultra violet curing printing ink and varnish. The results showed that ultra violet curing printing technology in food contact applications is an important research area, with further research possibly being able to redeem the UV technologies' bad reputation within the packaging supply chain.

Andean indigenous food crops: nutritional value and bioactive compounds

The Andean area of South America is a very important center for the domestication of food crops. This area is the botanical origin of potato, peanut and tomato. Less well- known crops, such as quinoa (Chenopodium quinoa), kañiwa (Chenopodium pallidicaule) and kiwicha (Amaranthus caudatus), were also domesticated by ancient Andean farmers. These crops have a long history of safe use with the local populations and they have contributed to the nutrition and wellbeing of the people for centuries. Several studies have reported the nutritional value of Andean grains. They contain proteins with a balanced essential amino acid composition that are of high biological value, good quality oil and essential minerals, for example iron, calcium and zinc. They are potential sources of bioactive compounds such as polyphenols and dietary fiber. The main objective of the practical work was to assess the nutritional value of Andean native grains with a special emphasis on the bioactive components and the impact of processing. The compounds studied were phenolic acids, flavonoids, betalains and dietary fiber. The radical scavenging activity was measured as well. Iron, calcium and zinc content and their bioavailability were analyzed as well. The grains were processed by extrusion with the aim to study the effect of processing on the chemical composition. Quinoa, kañiwa and kiwicha are very good sources of dietary fiber, especially of insoluble dietary fiber. The phenolic acid content in Andean crops was low compared with common cereals like wheat and rye, but was similar to levels found in oat, barley, corn and rice. The flavonoid content of quinoa and kañiwa was exceptionally high. Kiwicha did not contain quantifiable amounts of these compounds. Only one variety of kiwicha contained low amounts of betalains. These compounds were not detected in kañiwa or quinoa. Quinoa, kañiwa and kiwicha are good sources of minerals. Their calcium, zinc and iron content are higher than the content of these minerals in common cereals. In general, roasting did not affect significantly mineral bioavailability. On the contrary, in cooked grains, there was an increase in bioavailability of zinc and, in the case of kañiwa, also in iron and calcium bioavailability. In all cases, the contents of total and insoluble dietary fiber decreased during the extrusion process. At the same time, the content of soluble dietary fiber increased. The content of total phenolics, phytic acid and the antioxidant activity decreased in kiwicha varieties during the extrusion process. In the case of quinoa, the content of total phenolic compounds and the radical scavenging activity increased during the extrusion process in all varieties. Taken together, the studies presented here demonstrate that the Andean indigenous crops have excellent potential as sources of minerals, flavonoids and dietary fiber. Further studies should be conducted to characterize the phenolic compound and antioxidant composition in processed grains and end products. Quinoa, kañiwa and kiwicha grains are consumed widely in Andean countries but they also have a significant, worldwide potential as a new cultivated crop species and as an imported commodity from South America. Their inclusion in the diet has the potential to improve the intake of minerals and health-promoting bioactive compounds. They may also be interesting raw materials for special dietary foods and functional foods offering natural sources of specific health-promoting components.

An Infant with Food Allergy and Eczema in the Family – The Mental and Economic Burden of Caring

Allergic diseases including food allergy and eczema in an infant in combination with the everyday activities of caring for a family will pose challenges to parents. Only fragments of these challenges are revealed to health care professionals. Families have varying mental, social and economic resources to help them care for an allergic infant, and all such resources are important in determining how families succeed in meeting these challenges and the quality of the infant’s care. This study evaluated the whole burden to the family caused by an infant's allergic disease during the first 24 months of life. As the primary caregiver during this period is usually the mother, her perspective was considered important. Ecocultural theory, which considers families as capable of modifying the positive and negative forces facing them, was taken as the frame of reference. Data were collected as part of an ongoing prospective mother-infant study, and the methods included severity scoring of atopic dermatitis, dietary records, health-related quality of life measurements and assessments of the use of health care services and medications for treating the infant’s eczema, food allergy and asthma. Interviews with mothers were analysed by deductive content analysis on the basis of ecocultural theory and the family empowerment model. The theme “Living an ordinary family life” guided the organization of family activities essential for treating the infant's food allergy and eczema. These activities were sources of both strain and support for the mothers, the allergy-related supporting factors being the mother’s own knowledge of the allergy, hopes for an improvement in the infant’s condition, social support and work. An infant’s food allergy at the age of one year caused considerable strain for the mother in cases where the introduction of new foods into the child’s diet was delayed. This delay was still causing the mother additional strain when the child was 24 months of age. The infants waking at night at the ages of 12 and 24 months because of itching related to eczema caused strain for the mothers. The infants’ health-related quality of life was impaired at ages of 6 and 12 months compared with healthy infants. The principal reasons for impairments were itching, scratching and sleep disturbances at 6 and 12 months and treatment difficulties at 6 months. Problems with getting to sleep were reported at all stages irrespective of eczema and were also present in healthy infants. The economic impact of the treatment of allergic diseases on families during the first 24 months was 131 EUR (2006 value) in cases of eczema and 525 EUR in cases of food allergy. From the societal perspective, the costs of food allergy were a median of 3183 EUR (range 628–11 560 EUR) and of eczema a median of 275 EUR (range 94–1306 EUR). These large variations in costs in food allergy and eczema indicate that disease varies greatly . In conclusion, food allergy and eczema cause extra activities and costs to families which arrange these disease-related activities in such a way that they support the leading family theme “Living an ordinary family life”. Health care professionals should consider this thematic character of family life and disease-related activities in order to ensure that new treatments are sustainable, meaningful and tailored to daily activities. In addition, those mothers who are experiencing difficulties with food allergic infants or infants with eczema should be recognized early and provided with individual encouragement and support from health clinics. In the light of the present results, early detection of symptoms and effective parental guidance can contribute to the well-being and health-related quality of life of the child and family.

Climate driven changes in temperature, pH and food quality : effects on copepod reproduction

Increased emissions of greenhouse gases into the atmosphere are causing an anthropogenic climate change. The resulting global warming challenges the ability of organisms to adapt to the new temperature conditions. However, warming is not the only major threat. In marine environments, dissolution of carbon dioxide from the atmosphere causes a decrease in surface water pH, the so called ocean acidification. The temperature and acidification effects can interact, and create even larger problems for the marine flora and fauna than either of the effects would cause alone. I have used Baltic calanoid copepods (crustacean zooplankton) as my research object and studied their growth and stress responses using climate predictions projected for the next century. I have studied both direct temperature and pH effects on copepods, and indirect effects via their food: the changing phytoplankton spring bloom composition and toxic cyanobacterium. The main aims of my thesis were: 1) to find out how warming and acidification combined with a toxic cyanobacterium affect copepod reproductive success (egg production, egg viability, egg hatching success, offspring development) and oxidative balance (antioxidant capacity, oxidative damage), and 2) to reveal the possible food quality effects of spring phytoplankton bloom composition dominated by diatoms or dinoflagellates on reproducing copepods (egg production, egg hatching, RNA:DNA ratio). The two copepod genera used, Acartia sp. and Eurytemora affinis are the dominating mesozooplankton taxa (0.2 – 2 mm) in my study area the Gulf of Finland. The 20°C temperature seems to be within the tolerance limits of Acartia spp., because copepods can adapt to the temperature phenotypically by adjusting their body size. Copepods are also able to tolerate a pH decrease of 0.4 from present values, but the combination of warm water and decreased pH causes problems for them. In my studies, the copepod oxidative balance was negatively influenced by the interaction of these two environmental factors, and egg and nauplii production were lower at 20°C and lower pH, than at 20°C and ambient pH. However, presence of toxic cyanobacterium Nodularia spumigena improved the copepod oxidative balance and helped to resist the environmental stress, in question. In addition, adaptive maternal effects seem to be an important adaptation mechanism in a changing environment, but it depends on the condition of the female copepod and her diet how much she can invest in her offspring. I did not find systematic food quality difference between diatoms and dinoflagellates. There are both good and bad diatom and dinoflagellate species. Instead, the dominating species in the phytoplankton bloom composition has a central role in determining the food quality, although copepods aim at obtaining as a balanced diet as possible by foraging on several species. If the dominating species is of poor quality it can cause stress when ingested, or lead to non-optimal foraging if rejected. My thesis demonstrates that climate change induced water temperature and pH changes can cause problems to Baltic Sea copepod communities. However, their resilience depends substantially on their diet, and therefore the response of phytoplankton to the environmental changes. As copepods are an important link in pelagic food webs, their future success can have far reaching consequences, for example on fish stocks.

Exploring the role and transformative potential of human rights in development practice and food security : case study from Malawi

Avhandlingen är en analys av den roll som mänskliga rättigheter spelar i utvecklingssamarbete i allmänhet och tre matsäkerhetsprojekt i Malawi i synnerhet. Författaren undersöker huruvida mänskliga rättigheter kan bidra till samhälleliga förändringsprocesser. Undersökningen har en diskursiv syn på mänskliga rättigheter; rättigheter ses som sociala konstruktioner skapade av människor, konstruktioner som förändras i takt med att aktörerna ger dem ny mening. Människorättsbaserade utvecklingsstrategier riktar uppmärksamheten mot olika aktörers skyldigheter samt vikten av att mänskliga rättigheter inte kränks genom utvecklingspolitiska beslut. En analys som utgår från mänskliga rättigheter kan leda till att nya frågor lyfts fram: vem har skyldigheter, vem har rättigheter, och varför förverkligas inte dessa? Fokus flyttas till hur politiska, ekonomiska och juridiska strukturer kan förändras så att de främjar mänskliga rättigheter. Författaren använder empiriskt material från Malawi för att visa vilken roll mänskliga rättigheter och så kallade människorättsprinciper spelar inom tre projekt: (1) ett mathjälpsprojekt; (2) ett rättighetsbaserat projekt med fokus på att stärka strategier för livsuppehälle; (3) ett juridiskt projekt inom ramen för vilket man skapat ett lagförslag om rätten till föda. Analysen visar att det rättighetsbaserade projektet strävade efter den mest djupgående samhälleliga förändringen. Människorättsprinciperna ansvarighet och deltagande handlade inte endast om verksamheten inom projektet utan man strävade även efter att stärka dessa principer mellan medborgare och myndigheter. Rättigheter, som ett sätt att tala, tänka och handla, inte som abstrakta juridiska normer, påverkade de lokala aktörernas sätt att kräva bl.a. tjänster av lokala myndigheter. Teoretiskt kan man säga att det rättighetsbaserade projektet representerar ett aktörsperspektiv på mänskliga rättigheter där aktörernas egna uppfattningar om vad de är berättigade till samt krav på myndigheters ansvar formade vilken mening rättigheterna kom att få.
