Prvi izvještaji, istraživanja polenanalitičkog i ugljenisanog makrobotaničkog materijala neolitskog naselja Okolište (centralna Bosna)
Nastanak i razvoj neolitskih kultura na bosanskom području zavisi od niza faktora prirodne sredine. Pored geografskog položaja znatnu ulogu igraju klima, zemljište, kao i razvitak flore i faune. Radi toga su, kod projekta Okolište od samog početka istraživanja uključene razne naučne discipline. Paralelno uz arheološke radove (2002-2005) izvršene su geološke, arheobotaničke, zoološke i geomagnetske prospekcije, sa namjerom da različitim naučnim me…
Less alarming than assumed
Reforms have aimed to make the German educational system more permeable. Today, obtaining the highest level of secondary education is possible regardless of the track to which a student has transferred. However promising, research has indicated that these hopes of easier upward mobility have only been partially fulfilled, as many students who began their educational journeys on a non-academic track displayed diversion effects—that is, a loss of i…
Reading Begets Reading? Disentangling the Dynamic Interplay Between Reading Competence and Reading Exposure with a Special Focus on Gender Differences
Do children with better reading competence read more, or do avid readers increase their reading competence? This highly relevant question has been discussed for many years, yet conclusive results are rare. Previous studies suffer from small sample sizes or omitted variable bias, rendering their findings questionable. We provide new insight using large‐scale German panel data ( N > 5100). By surveying secondary school students (initial age = 11.1 …
On the influence of parents and peers on occupational aspirations in Germany under special regard of secondary school track interactions
International research has established that significant others, such as parents and peers, can influence a student’s educational or occupational aspirations. However, this research also reveals that influences differ by educational system, and the effects of peers are strongest in systems with low levels of stratification. For a long time, it was assumed that these effects were weaker in highly stratified systems, such as in Germany. However, our…
Investigating how early academic performance and parental socio-economic status predict and explain successful completion of secondary education in Germany
In educational sociology, it is of greatest interest to explain why some students are more successful than others and obtain higher educational qualifications or receive better grades, which can have long-lasting consequences. The present study compares the influence of early academic performance, which can be regarded as a proxy of overall intelligence, to the socio-economic status (SES) of the family, which measures how much a family can invest…
Why do low spirits last? Investigating correlates of cumulative unhappiness using German panel data
Experiencing states of unhappiness is normal and part of human existence. Yet, if these states occur often or for longer periods of time, this can become a large burden and greatly reduce a person’s overall quality of life. I refer to these states as cumulative unhappiness, and I empirically investigated which factors and variables are correlated with them. Using large-scale German panel data ( N = 8,646; mean age = 51.7 years, SD = 10.7 years), …
Children's aspirations, their perceptions of parental aspirations, and parents' factual aspirations-gaining insights into a complex world of interdependencies
Children's educational aspirations have been shown to be highly relevant for their educational trajectories and, therefore, researchers have tried to understand how and when these aspirations are formed. The influence of parental aspirations on the development of children's aspirations has often been the focus of such investigations in previous studies. Going beyond these earlier approaches, we address the question of how children's aspirations m…
High hopes but aiming low? Explaining why some families with high educational aspirations do not choose the academic track in German secondary education
Selecting a school track after primary schooling is an early and highly influential decision families have to make in the German educational system. Usually, families with high educational aspirations choose the academic track since it is the direct pathway to higher education eligibility, yet there are families selecting another track. Explaining this decision is highly relevant since it is known that other tracks can divert aspirations away fro…
Explaining inequalities of homeschooling in Germany during the first Covid-19 lockdown
Current studies suggest that the COVID-19 pandemic is worsening existing social inequalities in the field of education worldwide. In this paper, we argue that the pandemic is especially challenging for students from socially disadvantaged and educationally deprived homes, as parental engagement and resources are very important in terms of guiding and supporting students’ learning processes during this school closure period. To examine how well pa…
Less learned but still good grades (for some). What impact had school closures on social inequality of educational opportunity
Several studies have tried to estimate the effects of the COVID-19 pandemic on student learning and the learning differences between social groups. Few studies have looked at the effects on other aspects of students’ educational achievement, especially grades. Institutionally, grades are essential for evaluating students’ ability, for tracking, for graduation, and as a signal for the labor market. However, grades are subject to many non-performan…
Investigating the co-development of academic competencies and educational aspirations in German primary education
Academic achievement and educational decisions, which are strongly related to primary and secondary effects, are the two main drivers behind the emergence of social inequality in education. To understand this process in more detail, even before final decisions have to be made, the reciprocal influence of achievement and aspirations is of greatest interest. By not simply looking at an ultimate outcome but investigating its antecedents in a longitu…
Is there a dose-response relationship? Investigating the functional form between Covid-19 incidence rates and life satisfaction in a multilevel framework
While there is plenty of research linking the effects of the global COVID-19 pandemic to a drastic reduction of life satisfaction in the population, there is little information on the functional form of this relationship. Until now, one could suspect that this association is linear and a higher number of COVID-19 infections in a region leads to a continuous decline of satisfaction. However, there are reasons to assume that this interrelation is i…

When problems just bounce back
While in the past the concept of resilience was used to explain psychological well-being in extreme situations like enduring poverty, abuse, or war, it has now found broad application in numerous fields of research. It can also be applied to examine how everyday challenges and problems are dealt with, for example in the educational and university context. This raises the question of whether resilience and academic success are correlated. Using Ge…
Beyond the U-Shape
Classifying and explaining the causal and functional relationship between age and life satisfaction, especially in an international context, is still a major open question in demographics and happiness-research. Especially the debate whether to include sociodemographic control variables in these models has received much attention and deserves more discussion. The current contribution takes a cross-country perspective and attempts to sort countrie…
Analyse des Nutzens von Praktika für österreichische Hochschulabsolventen unter Einbezug relevanter Mediationspfade
Praktika sind für Hochschulabsolventen eine weitverbreitete Möglichkeit bereits während des Studiums Arbeitsmarkterfahrung zu sammeln und berufsbezogene Fähigkeiten zu erwerben. Allerdings ist weitgehend unklar, wie groß der tatsächliche Nutzen dieser Praktika für den Arbeitsmarkteinstieg ist und ob Einkommen, Passung des Berufs sowie Zufriedenheit signifikant beeinflusst werden. Zudem ist nicht ausreichend erforscht, ob Pflichtpraktika und freiw…
Applied usage and performance of statistical matching in bibliometrics
Controlling for confounding factors is one of the central aspects of quantitative research. Although methods such as linear regression models are common, their results can be misleading under certain conditions. We demonstrate how statistical matching can be utilized as an alternative that enables the inspection of post-matching balancing. This contribution serves as an empirical demonstration of matching in bibliometrics and discusses the advant…
Improving Data Quality with Sociodemographic Matching
According to the theory of liking, data quality might be improved in face-to-face survey settings when there is a high degree of similarity between respondents and interviewers, for example, with regard to gender or age. Using two rounds of European Social Survey data from 25 countries including more than 70,000 respondents, this concept is tested for the dependent variables amount of item nonresponse, reluctance to answer, and the probability th…
Eric C. Grimm 1951–2020
The untimely death of Eric Grimm on 15th November 2020 in Jefferson, South Dakota is a much regretted loss to the global community of palynologists to which he contributed so much. Eric was a distinguished research palaeoecologist, a skilful and amusing companion in the field and one of the most widely known palynologists of his generation (Fig. He is best remembered for his advocacy of open and shared international databases for fossil pollen an…
Bildung um jeden Preis? Über den Zusammenhang zwischen fehlender Gymnasialempfehlung und Entwicklung von Kompetenzen, Lebenszufriedenheit und anderer Faktoren in der Sekundarstufe
Bildung ist ein zentraler Prädiktor des beruflichen Erfolgs. Da dies Eltern bekannt ist, versuchen sie meistens ihren Kindern den Gymnasialbesuch zu ermöglichen, da dort der höchste Bildungsabschluss erworben werden kann. Dazu wird mitunter die Übergangsempfehlung ignoriert. Wie sich dies auf die weitere Entwicklung des Kindes auswirkt, ist bisher nur unzureichend bekannt. Die folgenden Analysen demonstrieren mittels Mehrebenen-Wachstumskurvenmod…
How does exposure to a different school track influence learning progress? Explaining scissor effects by track in Germany
Analysing Diversion Processes in German Secondary Education
Educational aspirations can be regarded as a predictor of final educational attainment, rendering this construct highly relevant for analysing the development of educational inequalities in panel data settings. In the context of the German tracked secondary school system, we analysed school-track effects on the development of educational aspirations. Using data from five consecutive waves of the National Educational Panel Study (NEPS), we selecte…
Diversion or Inclusion? Alternative Routes to Higher Education Eligibility and Inequality in Educational Attainment in Germany
In the 1960s, educational reforms have been initiated in Germany to make the rigid stratified school system more permeable. While maintaining between-school tracking in secondary education, several second-chance options have been introduced that established alternative routes to higher education. This study aims to evaluate whether these alternative routes were successful in reducing the levels of social inequality in both higher education eligib…

Landscape evolution and agro-sylvo-pastoral activities on the Gorgan Plain (NE Iran) in the last 6000 years
The Gorgan Plain (NE Iran) is characterized by fertile soils formed on a loess plateau and is at present primarily exploited for intensive agriculture. However, the timing and intensity of the human impact on the landscape in the past are still unclear. A sediment core, taken from the centre of the eastern Gorgan Plain in the Kongor Lake covering the major part of the Holocene from 6.1 to 0.8 ka (all ages are calibrated before present), has been …

Palaeoecology and Archaeology of the Kärlich–Seeufer Open-Air Site (Middle Pleistocene) in the Central Rhineland, Germany
The Kärlich–Seeufer archaeological site in Germany's central Rhineland was excavated between 1980 and 1992. The site provides evidence for hominid activity during a Middle Pleistocene interglaciation known up to now only from the Kärlich clay pit and therefore defined as the Kärlich Interglaciation, which is considered to be post-Cromer IV and pre-Holstein ( sensu stricto ) in age. The site is characterized by Acheulean artifacts, a fauna dominat…
Impact of the Late Glacial Eruption of the Laacher See Volcano, Central Rhineland, Germany
Within a period of a few weeks toward the end of the Allerød Interstadial, the major Plinian eruption of the Laacher See volcano produced some 20 km 3 of eruptiva, covering and preserving the late-glacial landscape in the German Central Rhineland over an area of more than 1000 km 2 . Correlation of terrestrial archives with the Greenland ice-core records and improved calibration of the radiocarbon timescale permit a precise, accurate age determin…

Dating Archaeological Cultures by Their Moats? A Case Study from the Early Bronze Age Settlement Fidvár near Vráble, SW Slovakia
This article uses age-depth models based on 29 accelerator mass spectrometry (AMS) dates from charred plant macroremains (seeds, chaff), wood charcoal, and snail shells found in two moats from the settlement Fidvár near Vráble (SW Slovakia) to improve the absolute chronology of the Early Bronze Age in central Europe. The charred macroremains were taxonomically identified to species or genus level and the lifespan of the objects and the archaeolog…
Beaver ( Castor fiber ) Activity in an Archaeological Context
Bioturbation and intrusive ecofacts are major concerns for the analysis of archaeological sites in wetland environments. Post-sedimentary influence of beavers (Castor fiber) is described for a well dated Late Palaeolithic archaeological record situated in a floodplain in Northern Germany. An extensive burrow system was documented and analysed according to its spatial dimensions and sedimentological properties; it was interpreted to be the result …

New AMS 14C dates track the arrival and spread of broomcorn millet cultivation and agricultural change in prehistoric Europe
Broomcorn millet ( Panicum miliaceum L.) is not one of the founder crops domesticated in Southwest Asia in the early Holocene, but was domesticated in northeast China by 6000 bc . In Europe, millet was reported in Early Neolithic contexts formed by 6000 bc , but recent radiocarbon dating of a dozen 'early' grains cast doubt on these claims. Archaeobotanical evidence reveals that millet was common in Europe from the 2nd millennium bc , when major …
