Onko tiede jakamaton?

Tieteen päiviä edeltäneessä Tieteessä tapahtuu - lehdessä (8/1998) Jan Rydman tähdensi tieteen yhtenäisyyttä ja jakamattomuutta keskeisenä kulttuurisena voimana. Tieteen tekijät esiintyvät yhdessä yliopistoissa, tieteen keskusjärjestöissä ja Tieteen päivillä sekä edustavat yhteisiä sivistyksellisiä arvoja

Yliopistosivistyneistön asema ja tehtävät yhteiskunnassa

Yliopistosivistyneistön aseman ja roolin muutokset ovat selvästi kuvastuneet maamme poliittisessa elämässä. On usein viitattu siihen miten maamme yliopistosivistyneistö ratkaisevasti vaikutti Suomen itsenäistymiseen ja eurooppalaiseksi valtioksi kasvamiseen. Varsinkin monet professorit saattoivat aivan omasta takaa, valtaeliittiin ja säätyläissivistyneistöön kuuluvina, aktiivisesti toimia ja vaikuttaa valtakunnallisessa politiikassa.Mutta onko yliopistosivistyneistöllämme enää tätä asemaa

Tutkimustraditiot tieteessä

Varsinkin pienten maiden akateemisessa elämässä suurten yksilöiden aikaansaannokset ovat olleet sekä siunaukselliset että pulmalliset. Tärkeiden uusien ideoiden ja tuloksien esittäjät ja kehittäjät luovat vahvoja perinteitä, jotka suuresti inspiroivat muita tutkijoita. Jossakin vaiheessa tieteellisten perinteiden seuraaminen saattaa kuitenkin johtaa tyhjäkäyntiin siten, että tutkimus joko asianomaisella laitoksella tai jopa koko maassa on jäämässä kehityksestä jälkeen

Tieteelliset seurat tieteessä ja yhteiskunnassa

Kuuluisat tieteen filosofit ovat tähdentäneet miten tiede tietoa etsivänä järjestelmänä perustuu tutkijoiden yhteistyöhön ja vielä voimakkaammin sanottuna, miten tiede perustuu sosiaaliseen periaatteeseen ja miten tutkijoiden muodostama tiedeyhteisö on tieteen varsinainen subjekti. Tutkijoiden yhteistyöllä saavutetulla yhteisymmärryksellä ratkaistaan mikä on sekä totta, virheellistä että hedelmällistä tieteellisessä työskentelyssä

Perspektiv och perspektivförskjutningar inom nordisk

Paradigms and vicissitudes in the perspectives of 20th century Nordic sociology Both as regards its own development and its cultural impact 20th century was an era of sociology. There was, however, in the central focuses considerable vicissitudes, clearly observable in the sociology of the Nordic countries, Denmark, Finland, Iceland, Norway, and Sweden. The de-velopmental patterns can be divided into three periods: (1) an emphasis on evolution and evolutionary explanations of social behavior up to the First World War, (2) a during most of the century prevailing dominance of a sociology emphasizing socialization and societies as wholes with their social structure, normative rules and social func-tions, and (3) at the end of the century an emerging rise of a new view of social life with an accentuation of uncer-tainty, agency, and semiotic interpretation. The institu-tionalization of Nordic academic sociology occurred in the 1940’s, 1950’s and 1960’s. Towards the end of this period reorientations and protests against the prevailing sociology began to emerge. The dominant research interests today may be summed up in the following four orientations:cultural sociology with an emphasis on semiotic constructions of reality, feminist studies with a special interest in gendered experiences of women, studies of the conditions of the Nordic welfare state, and historically oriented macro social science with a focus on large-scale both European and global trans-formations

Sociologiens janushoved(er)

The Janus Face(s) of Sociology There exists in sociology a continuous tension between a positivitic and herme¬neutic approach. Sociologists perform many activities in a similar manner as natural scientists do. They try to gather data about observable events in a syste¬matic and painstaking manner, and they try to discover regularities and invariant forms in social action and society. On the other hand sociologists are future¬-oriented and many of their theories and concepts are built on images of a world, that has never yet existed. Concepts such as democracy, the welfare state and eco¬nomic equilibrium are ideal images, ne¬ver fully attained. It is important in socio¬logy to work and generalise on observa¬ble data, but it is also important to reali¬se that there are no simple social facts. In societies and social life unpredictable events and situations will always occur. People have begun to see the world and also act in an entirely new way. This due to the open nature of social reality. It does not make social sciences obsolete, but it contains a warning against confident predictions of social tendencies. The polarity and tension between an atomistic, individualist pole and a com¬munitarian, cultural pole is one of the deepest and most pervasive themes in modern thought. In the social sciences this polarity is represented in a dividing line between a structural and a cultural approach. There are good grounds for maintaining that most social phenome¬na can not be explained and understood properly unless both these two approa¬ches are used. The dichotomy between a structural and a cultural approach or a distinction between Gesellschaft and Ge¬meinschaft has been part of sociology for most of its life as a scientific discipline. The present global and social develop¬ments - globalization - have intensified this conflict between instrumental ra¬tionality and the need for communal and cultural identity. Consequently, it has al¬so led to growing efforts in combining the two approaches mentioned above either within sociology in the attempts of combining positivistic and hermeneu¬tic research traditions in addressing the social problems or in the efforts of socio¬logists forming creative and efficient net¬works between sociology and scholars from other disciplines. Both efforts are presently the fertile path in the social sciences but it makes it necessary to be very open to what is happening within other social and human sciences

Protein intake in children and growth and risk of overweight or obesity : A systematic review and meta-analysis

Objectives: The aim of this study was to examine the evidence for an association between the dietary protein intake in children and the growth and risk of overweight or obesity up to 18 years of age in settings relevant for the Nordic countries. Methods: We searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and Scopus up to February 26, 2021 for randomized controlled trials (RCTs) or prospective cohort studies assessing for protein intake from foods (total and from different sources) in children. The outcomes include weight, height/length, adiposity indices, and/or risk of overweight and/or obesity. The risk of bias was evaluated with instruments for each respective design (Cochrane’s Risk of Bias 2.0 and RoB-NObS). A meta-analysis of five cohort studies was performed. The evidence was classified according to the criteria of the World Cancer Research Fund. Results: The literature search resulted in 9,132 abstracts, of which 55 papers were identified as potentially relevant. In total, 21 studies from 27 publications were included, of which five were RCTs and 16 were cohort studies. The RCTs found generally null effects of high-protein intake in infants on weight gain, nor that lower protein diets negatively affected growth. All included RCTs had some concern regarding the risk of bias and were limited by small sample sizes. Total protein intake and BMI were assessed in 12 cohorts, of which 11 found positive associations. The meta-analysis revealed a pooled effect estimate of 0.06 (95% CI 0.03, 0.1) kg/m2 BMI per one E% increment in total protein (I2 = 15.5). Therefore, the evidence for a positive relationship between total protein intake and BMI was considered probable. Furthermore, there was probable evidence for an association between higher intake of animal protein and increased BMI. There was limited, suggestive evidence for an effect of total protein intake and higher risk of overweight and/or obesity, while no conclusions could be made on the associations between animal vs. plant protein intake and risk of overweight and/or obesity. Discussion: In healthy, well-nourished children of Western populations, there is probably a causal relationship between a high-protein intake in early childhood (≤ 18 months) – particularly protein of animal origin – and higher BMI later in childhood, with consistent findings across cohort studies. A lack of RCTs precluded a stronger grading of the evidence.Peer reviewe

Supplementation with long chain n-3 fatty acids during pregnancy, lactation, or infancy in relation to risk of asthma and atopic disease during childhood : a systematic review and meta-analysis of randomized controlled clinical trials

Objective: To assess whether supplementation with long chain n-3 fatty acids during pregnancy, lactation, or infancy reduces the risk of developing asthma or atopic disease during childhood.Methods: Searches were performed in MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and Scopus up to 2021-09-20, for randomized controlled trials (RCTs) that investigated the effect of supple-mental long chain n-3 fatty acids during pregnancy, lactation, or infancy for the prevention of childhood asthma or allergy. Article selection, data extraction, and risk of bias assessment (Cochrane's Risk of Bias 2.0) were independently conducted by two assessors. The evidence was synthesized qualitatively according to the criteria of the World Cancer Research Fund and meta-analyzed.Results: A total of nine RCTs met inclusion criteria; six were conducted during pregnancy, two during infancy, and one during both pregnancy and infancy. Meta-analysis showed that long chain n-3 fatty acid supplementation during pregnancy significantly reduced the risk of asthma/wheeze in the child (RR 0.62 [95% confidence interval 0.34-0.91], P = 0.005, I2 = 67.4%), but not other outcomes. Supplementation during lactation of infancy showed no effects on any outcome. The strength of evidence that long chain n-3 fatty acid supplementation during pregnancy reduces risk of asthma/wheeze in the offspring was con-sidered limited - suggestive. No conclusion could be made for the effects of long chain n-3 fatty acid supplementation during pregnancy for other atopic diseases, or for supplementation during lactation or infancy for any outcome. Conclusion: The intake of long chain n-3 fatty acid supplements during pregnancy may reduce the risk of asthma and/or wheeze in the offspring, but the strength of evidence is low. There is inconclusive evidence for the effects of long chain n-3 fatty acid supplements during pregnancy for other outcomes, as well as for sup-plementation during lactation or infancy.Peer reviewe

Quality of dietary fat and risk of Alzheimer's disease and dementia in adults aged >= 50 years : a systematic review

Objective: To identify, critically appraise, and synthesize evidence on the effect of quality of dietary fat intake and different classes of fatty acids on the risk of Alzheimer's disease (AD) and dementia in adults aged >= 50 years. Methods: We searched MEDLINE, EMBASE, Cochrane Central of Controlled Trials, and Scopus for clinical trials and prospective cohort studies published until May 2021. Two reviewers independently screened retrieved literature, extracted relevant data, and performed risk of bias assessment. Classes of fatty acids included were saturated fatty acids (SFAs), trans fatty acids (TFAs), monounsaturated fatty acids (MUFAs), poly-unsaturated fatty acids (PUFAs), and their subtypes and sources. Given between-study heterogeneity, we did not perform meta-analyses but narratively described findings from the studies. Results: From 4,491 identified records, five articles (based on four prospective cohort studies) met the inclusion criteria. Three studies had an overall serious risk of bias, while one study had a moderate risk. Overall, we found no robust association between intake of any fatty acids type and the development of AD and dementia. For example, for SFA and TFA, there was contradictory associations reported on AD: one study found that each unit increase in energy-adjusted intake of SFA (risk ratio (RR) 0.83, 95%CI 0.70 0.98) and TFA (RR 0.80, 95%CI 0.65-0.97) was associated with a decreased risk of AD, but not dementia. For PUFA, one study found that higher quintile intake of marine-based n-3 PUFA was associated with a decreased risk of AD. The intake of other fatty acids was not associated with the outcomes. The certainty of the overall evidence was inconclusive. Conclusion: We found no clear association between the intake of various classes of fatty acids and the risk of AD and dementia in adults. More well-designed prospective studies are required to clarify these findings.Peer reviewe
