Content of zinc, iron and their absorption inhibitors in Nicaraguan common beans (Phaseolus vulgaris L.).

Protein-energy malnutrition and mineral deficiencies are two of the three forms of nutritional deficiencies that affect most developing countries due to inadequate access to food and diets based on a sole crop. Common bean (Phaseolus vulgaris L.) is the staple crop of Nicaragua and it has the potential to improve the nutritional status of the poorest group of the nation. Its high content of both protein and nonhaem iron provides many nutrients, but inhibitors also may prevent absorption of iron and zinc by the human consumer. A proper production chain must be followed to ensure the best grain quality for the consumer. To achieve food security, both production and high nutritional content must be maintained. Four nationally important accessions of common bean, with different harvesting dates, were selected to be submitted to two treatments: to evaluate the impact of storage conditions on the end quality of the grain. The duration of the study was six months with sampling every six weeks, and the two treatments were controlled one stored at 40°C and 75 RH %, and the other was stored in in-situ conditions. Proximate and mineral composition was evaluated as well as tannin, phytate and bioavailability. Significant differences among different accessions were found, being the most significant in protein, Fe and Zn content, tannins and phytate. Protein values ranged from 21-23%. Iron content was 61-81 mg/kg but only 3-4% was bioavailable. Zinc content was 21-25 mg/kg and 10-12% was bioavailable. The concentration of phytate ranged from 8.6-9.6 mg/g while tannin values ranged within 37.7-43.8 mg/g. Storage at high temperatures was demonstrated to have an impact on certain nutritional compounds and proved detrimental to final grain quality. Soluble sugar content and tannin content decreased after six months in both storage conditions, IDF decreased in the in-situ and SDF in the stress. The iron content and bioavailability in INTA Biofortificado were not as outstanding as expected, so experiments should be conducted to compare its iron uptake and delivery with other cultivars.

Druvan - Den personalekonomiska nyttan av mångdimensionell företagshälsovårds- och personalutvecklingsverksamhet baserad på Metal Age-konceptet i Dragsfjärds kommun (2002-2005)

Under åren 2002-2005 förverkligades Druvan-projektet i Dragsfjärds kommun, vilket innebar en dramatisk ökning av företagshälsovårdsinsatserna. Företagshälsovårdsutgifterna ökade från 20 € per anställd till över 400 €. Den totala satsningen på personalens hälsa ökade ännu mer. Innehållet i Druvan baserade sig på den s.k. Metal Age-metoden. Metoden går ut på att arbetsgemenskapen tillsammans identifierar utvecklingsbehov och –åtgärder. Projektet ledde till en stor mängd utvecklingsåtgärder och därpå följande effekter på personalens hälsa, trivsel och samarbete. Som en del av åtgärderna utarbetade kommunen en personalrapport för de aktuella åren. Under projekttiden utvecklades personalens arbetsförmåga betydligt gynnsammare än förväntat. Den ekonomiska analysen visade att det investerade kapitalet gav en avkastning på 46%. Nyttan uppkom som resultat av minskad sjukfrånvaro och färre förtidspensioneringar. Druvan-projektet stöder de tidigare bedömningarna, enligt vilka det finns ett klart utrymme för att öka satsningarna på företagshälsovård i vårt land. Detta gäller speciellt arbetsplatser vars satsningar på företagshälsovård är betydligt under genomsnittet. Dragsfjärds kommun har beslutat göra Druvan till en bestående struktur inom kommunen. Guy Ahonen är professor i Knowledge Management, speciellt personalekonomi vid institutionen för företagsledning och organisation vid Hanken. Ove Näsman är ledande företagsläkare vid Dalmed OyAb i Dalsbruk i sydvästra Finland. Båda har forskat i årtionden kring effekterna av ökat välbefinnande i arbetet.

The determinants of sexually transmitted infections among reproductive age women in St. Petersburg, Estonia and Finland

OBJECTIVES: Sexually transmitted infections' (STIs) rate vary in St. Petersburg, Estonia and Finland; the aim was to compare the determinants of self-reported sexually transmitted infections in these areas. METHODS: Data from four population-based questionnaire surveys were used (Finland in 1992 and 1999; St. Petersburg in 2003; Estonia in 2004). With the exception of the 1992 Finnish survey (interview) all were postal surveys, with 1,070 respondents in Finland (78 and 52% response rates), 1,147 (68%) in St. Petersburg, and 5,190 (54%) in Estonia. RESULTS: Risky sexual behaviours were equally common in the three areas and the determinants were the same. Women with an STIs history more often had had their first sexual intercourse when aged under 18, had not used condom during first intercourse, had a high number of lifetime or previous year sexual partners. However, marital status and education were not similar determinants. Cohabiting and well-educated women in Finland were more likely to have STIs while in other areas the associations found were not statistically significant. CONCLUSIONS: Risky behaviour predicts STIs, but does not explain the varying rates of STIs between areas.

Studies on Stone Age Housepits in Fennoscandia (4000 - 2000 cal BC) : Changes in ground plan, site location and degree of sedentism

Housepits have a remarkably short research history as compared to Fennoscandian archaeological research on the Stone Age in general. The current understanding of the numbers and the distribution of Stone Age housepits in the Nordic countries has, for the most part, been shaped by archaeological studies carried out over the last twenty to thirty years. The main subjects of this research are Neolithic housepits, which are archaeological remains of semi-subterranean pithouses. This dissertation consists of five peer-reviewed articles and a synthesis paper. The articles deal with the development of housepits as seen in the data gathered from Finland (the Lake Saimaa area and south-eastern Finland) and Russia (the Karelian Isthmus). This synthesis expands the discussion of the changes observed in the Papers to include Fennoscandian housepit research as a whole. Certain changes in the size, shape, environmental location, and clustering of housepits extended into various cultures and ecological zones in northern Fennoscandia. Previously, the evolution of housepits has been interpreted to have been caused by the adaptation of Neolithic societies to prevailing environmental circumstances or to re-organization following contacts with the agrarian Corded Ware/Battle Axe Cultures spreading to North. This dissertation argues for two waves of change in the pithouse building tradition. Both waves brought with them certain changes in the pithouses themselves and in the practices of locating the dwellings in the environment/landscape. The changes in housepits do not go hand in hand with other changes in material culture, nor are the changes restricted to certain ecological environments. Based on current information, it appears that the changes relate primarily to the spread of new concepts of housing and possibly to new technology, as opposed to representing merely a local response to environmental factors. This development commenced already before the birth of the Corded Ware/Battle Axe Cultures. Therefore, the changes are argued to have resulted from the spreading of new ideas through the same networks that actively distributed commodities, exotic goods, and raw materials over vast areas between the southern Baltic Sea, the north-west Russian forest zone, and Fennoscandia.

Determinants of Cognitive Impairment in Old Age and Their Genetic Architecture

Cognitive health is of central importance for independent and balanced old age, while memory disorders represent the leading cause of intensive and long-term care among the Finnish elderly. The aims of this study were to analyse the effect of height, body mass index, weight change, metabolic conditions and coffee drinking in midlife on cognitive performance in old age among a sample of 2606 Finnish twins aged 65 years or older who had participated in a telephone interview to assess their cognitive status. Since coffee drinking associates with several metabolic conditions and Finns are known to be the greatest consumers of coffee in the world, the heritability and stability of coffee drinking was analysed in the whole Older Finnish Twin Cohort (n=10716). In order to investigate the association between height and cognitive performance in a population with more supportive childhood living conditions, a total of 2161 Danish twins were included in this study. A greater height was found to clearly associate with better cognitive performance in Finnish subjects, but less so among the Danish sample, which may reflect the childhood environmental differences between these cohorts. In the Finnish subjects, there was greater variance in cognitive performance among shorter subjects, and environmental factors were found to play a greater role in their cognitive performance, whereas the cognitive performance of taller participants was mainly explained by genetic factors. Midlife metabolic variables that were found to be significantly associated with a poorer cognitive performance in old age included a higher body mass index and three metabolic conditions: cardiovascular disease, hypertension and, most significantly of all, diabetes. Moreover, both weight gain and loss, even to a lesser degree than suggested previously, were found to be associated with poorer cognition. Furthermore, evidence of a causal relationship between midlife cardiovascular disease and cognitive performance in old age was demonstrated among discordant twin pairs. Conversely, no effect of coffee drinking in midlife on cognitive performance in old age was observed, although coffee drinking was demonstrated to be stable in the study population. The heritability of coffee drinking was found to differ across sexes and age groups, being 51% in men and 52% in women in the whole study population. This study supports the contention that cognitive performance in old age reflects the effects of multiple genetic and environmental exposures, including their complex interactions during the life-span. The demonstrated associations and evidence of a causal pathway between potentially preventable exposures and poorer cognitive performance highlight the importance of preventive medicine.

Peeking through the Iron Curtain: Memories of Watching Finnish Television in Estonia during Soviet Occupation

The present study analyses the memories of watching Finnish television in Estonia during the last decades of the Soviet occupation from the late 1960s until the beginning of 1990s. The study stems from a culturalist approach, perceiving television as a relevant aspect in the audiences’ everyday lives. It explores the significance of Finnish television on the society of occupied Estonia from the point of view of its historical audiences. The literature review concentrates on concepts such as the power of television, transnational media, historical audience reception and memory as an object of research. It also explains the concept of spillover, which refers to the unintentional bilateral flow of television signals from one country to another. Despite the numerous efforts of the Soviet authorities to prevent the viewing of the "bourgeois television", there still remained a small gap in the Iron Curtain. The study describes the phenomenon of watching Finnish television in Estonia. It provides understanding about the significance of watching Finnish television in Soviet Estonia through the experiences of its former audience. In addition, it explores what do people remember about watching Finnish television, and why. The empirical data was acquired from peoples’ personal memories through the analysis of private interviews and written responses during the period from February 2010 to February 2011. A total of 85 responses (5 interviews and 83 written responses) were analysed. The research employed the methods of oral history and memory studies. The main theoretical sources of the study include the works of Mati Graf and Heikki Roiko-Jokela, Hagi Šein, Sonia Livingstone, Janet Staiger and Emily Keightley. The study concludes that besides fulfilling the role of an entertainer and an informer, Finnish television enabled its Estonian audiences to gain entry into the imaginary world. Access to this imaginary world was so important, that the viewers engaged in illegal activities and gained special skills, whereby a phenomenon of "television tourism" developed. Most of the memories about Finnish television are vivid and similar. The latter indicates both the reliability and the collectiveness of such memories, which in return give shape to collective identities. Thus, for the Estonian viewers, the experience of watching Finnish television during the Soviet occupation has became part of their identity.

Does the age of fine root carbon indicate the age of fine roots in boreal forests?

To test the reliability of the radiocarbon method for determining root age, we analyzed fine roots (originating from the years 1985 to 1993) from ingrowth cores with known maximum root age (1 to 6 years old). For this purpose, three Scots pine (Pinus sylvestris L.) stands were selected from boreal forests in Finland. We analyzed root 14C age by the radiocarbon method and compared it with the above-mentioned known maximum fine root age. In general, ages determined by the two methods (root 14C age and ingrowth core root maximum age) were in agreement with each other for roots of small diameter (<0.5mm). By contrast, in most of the samples of fine roots of larger diameter (1.5-2mm), the 14C age of root samples of 1987-89 exceeded the ingrowth core root maximum age by 1-10 years. This shows that these roots had received a large amount of older stored carbon from unknown sources in addition to atmospheric CO2 directly from photosynthesis. We conclude that the 14C signature of fine roots, especially those of larger diameter, may not always be indicative of root age, and that further studies are needed concerning the extent of possible root uptake of older carbon and its residence time in roots.
