Data quality in content analysis: the case of the comparative manifestos project

'Die Inhaltsanalyse stellt vielfältige Techniken für die reliable und valide Analyse von Texten zur Verfügung, die entsprechend der Kontexte der Texte und der zu erschließenden analytischen Konzepte auf die spezifischen Erfordernisse der jeweiligen Projekte zugeschnitten werden müssen. Dies gilt insbesondere für langfristig und breit angelegte Projekte wie unser Manifesto-Projekt, mit dem seit drei Jahrzehnten Veränderungen parteipolitischer Präferenzen auf der Basis von klassischen Inhaltsanalysen komparativ für alte und neue Demokratien gemessen werden. Bei diesem Ansatz weisen methodisch geschulte Experten spezifische programmatische Ziele und Positionen, die sich bei Parteien, Wahlen und Ländern unterscheiden, einer vorgegebenen Klassifikation von grundlegenden, abstrakten, sowie in Zeit und Raum invarianten Politikpräferenzen zu. Der vorliegende Artikel beleuchtet an diesem Beispiel die Entwicklung von Standards der Qualitätssicherung inhaltsanalytischer Daten. Ausgehend von Krippendorfs (2006) methodologischem Ansatz argumentieren die Autoren, dass die Komplexität der Entstehungs- und Verwendungszusammenhänge von Texten die Auswahl der inhaltsanalytischen Methoden, insbesondere die Wahl zwischen klassischen und computergestützten Ansätzen, bestimmt.' (Autorenreferat)'While textbooks offer numerous devices for enhancing and testing the data quality of content analysis, all tools must be tailored in line with the contexts of the text and the analytical concepts of research. This is particularly the case in a long-term project such as ours that has continued for three decades to code election programs of all significant parliamentary parties in old and new representative democracies since World-War II for the purpose of measuring policy preferences of political parties. This article starts with a discussion of the strengths and weaknesses of the two basic types of quantitative approaches - human-based and computer-based content analysis. The basic features of the authors' classical human-based approach for estimating parties' policy preferences are outlined by reference to Krippendorf's (2006) typologies of reliability and validity. The conclusions highlight implications of the contexts of manifestos and the concepts applied to them for providing high quality manifesto data across party systems and elections.'

Democratic party government : formation and functioning in twenty-one countries

What are elections for? conferring the median mandate

Democracy is often described as a system in which a majority of electors choose one out of a number of competing parties to form a government and carry out its programme. Unfortunately, spontaneous majorities rarely form in support of one party. We generalize from a 'government' to a 'median' mandate, in which the median elector chooses the pivotal party in parliament, which then translates his or her preferences into public policy. To check this we investigate how accurately parliaments and governments represent the left-right position of the median voter in each of twenty parliamentary democracies. Distortions depend on the type of electoral arrangement, being relatively smaller under proportional representation than under single-member districts. Distortions do not equate to biased representation, however. Once we consider how distortions at one step or one time are compensated by distortions in the opposite direction at another, overall representation of the median voter position is reasonably accurate

The placenta, maternal diet and adipose tissue development in the newborn

Background: A majority of adipose tissue present in the newborn possess the unique mitochondrial protein, uncoupling protein (UCP1). It is thus highly metabolically active and capable of producing 300 times more heat per unit mass than any other organ in the body. The extent to which maternal obesity and/or an obesogenic diet impacts on placental function thereby resetting the relative distribution of different types of fat in the fetus is unknown. Summary: Developmentally the majority (if not all) fat in the fetus can be considered as classical brown fat, in which UCP1 is highly abundant. In contrast, beige (or recruitable) fat which possess 90% less UCP1 may only appear after birth, as a majority of fat depots undergo a pronounced transformation that is usually accompanied by the loss of UCP1. The extent to which this process can be modulated in a depot-specific manner and/or changes in the maternal metabolic environment remain unknown. Key Messages: An increased understanding of the mechanism by which offspring born to mothers possess excessive adipose tissue could enable sustainable interventions designed to promote the abundance of UCP1 possessing adipocytes. Ultimately, this would increase their energy expenditure and improve glucose homeostasis in these individuals

Sex differences in metabolic and adipose tissue responses to juvenile-onset obesity in sheep

Sex is a major factor determining adipose tissue distribution and the subsequent adverse effects of obesity-related disease including type 2 diabetes. The role of gender on juvenile obesity and the accompanying metabolic and inflammatory responses is not well established. Using an ovine model of juvenile onset obesity induced by reduced physical activity, we examined the effect of gender on metabolic, circulatory, and related inflammatory and energy-sensing profiles of the major adipose tissue depots. Despite a similar increase in fat mass with obesity between genders, males demonstrated a higher storage capacity of lipids within perirenal-abdominal adipocytes and exhibited raised insulin. In contrast, obese females became hypercortisolemic, a response that was positively correlated with central fat mass. Analysis of gene expression in perirenal-abdominal adipose tissue demonstrated the stimulation of inflammatory markers in males, but not females, with obesity. Obese females displayed increased expression of genes involved in the glucocorticoid axis and energy sensing in perirenal-abdominal, but not omental, adipose tissue, indicating a depot-specific mechanism that may be protective from the adverse effects of metabolic dysfunction and inflammation. In conclusion, young males are at a greater risk than females to the onset of comorbidities associated with juvenile-onset obesity. These sex-specific differences in cortisol and adipose tissue could explain the earlier onset of the metabolic-related diseases in males compared with females after obesity

Caffeine exposure induces browning features in adipose tissue in vitro and in vivo

Brown adipose tissue (BAT) is able to rapidly generate heat and metabolise macronutrients, such as glucose and lipids, through activation of mitochondrial uncoupling protein 1 (UCP1). Diet can modulate UCP1 function but the capacity of individual nutrients to promote the abundance and activity of UCP1 is not well established. Caffeine consumption has been associated with loss of body weight and increased energy expenditure, but whether it can activate UCP1 is unknown. This study examined the effect of caffeine on BAT thermogenesis in vitro and in vivo. Stem cell-derived adipocytes exposed to caffeine (1mM) showed increased UCP1 protein abundance and cell metabolism with enhanced oxygen consumption and proton leak. These functional responses were associated with browning-like structural changes in mitochondrial and lipid droplet content. Caffeine also increased peroxisome proliferator-activated receptor gamma coactivator 1-alpha expression and mitochondrial biogenesis, together with a number of BAT selective and beige gene markers. In vivo, drinking coffee (but not water) stimulated the temperature of the supraclavicular region, which co-locates to the main region of BAT in adult humans, and is indicative of thermogenesis. Taken together, these results demonstrate that caffeine can promote BAT function at thermoneutrality and may have the potential to be used therapeutically in adult humans

How Do Different Sources of Partisanship Influence Government Accountability in Europe?

The possibility of holding representatives to account through regular elections is one of the cornerstones of representative democracy. The precise role of partisanship in doing this has not been extensively examined. Using survey data from Europe (2002–2012), we show that partisanship can weaken or strengthen accountability, depending on its sources. If it is an affective-psychological attitude, as the Michigan school suggests, then it weakens accountability because it acts as a perceptual screen. If, however, it is a calculation of party performance which is constantly updated by citizens, then it strengthens accountability. The findings suggest that partisanship in Europe has been quite responsive to performance over the ten-year period. Instead of acting as a screen that inhibits accountability, partisanship appears rooted in calculations of party performance and so enhances accountability. However, the effects are asymmetric with left-leaning partisans more sensitive to the performance of their governments than right-leaning partisans
