We study empirically the role of education, age structure and other socioeconomic factors as a determinant of the transition to stable democratic regimes. Our findings suggest that educational improvements (in particular in primary education) and policies towards reducing inequalities in educational attainment play a particularly important role as a catalyst of sustainable democratization processes.

Analysis and forecast of the number and demographic structure of dentists in the Czech Republic Abstract Demographic aging and the associated fear of shortage of dentists in the near future is currently frequent topic. This problem is caused in the late seventies and early eighties, when unusually large number of graduates of dental disciplines finished studium and became dentists. In the next few years, the number of graduates declined significantly, and then held for decades at a constant level. This dominant age category of dentists has currently reached retirement age. A large number of old dentists provoked a reaction in the form of re-increase university capacity and current number of graduates is comparable with numbers in the period before 35-40 years ago. The purpose of this paper is to examine this changes and decide, if this changes were sufficient to keep current situation in the field of dental health care. Keywords: dentists, aging of dentists, forecast, age structure, Czech Republic

The total size of the world population is likely to increase from its current 7 billion to 8-10 billion by 2050. This uncertainty is because of unknown future fertility and mortality trends in different parts of the world. But the young age structure of the population and the fact that in much of Africa and Western Asia, fertility is still very high makes an increase by at least one more billion almost certain. Virtually, all the increase will happen in the developing world. For the second half of the century, population stabilization and the onset of a decline are likely. In addition to the future size of the population, its distribution by age, sex, level of educational attainment and place of residence are of specific importance for studying future food security. The paper provides a detailed discussion of different relevant dimensions in population projections and an evaluation of the methods and assumptions used in current global population projections and in particular those produced by the United Nations and by IIASA.

In this thesis we investigate the scarcely analyzed relationship between entrepreneurial activity in the form of company start-ups in Sweden and age demographics. Using a panel data set with data from all 21 Swedish regions from 1989 to 2019, we test what impact different age groups have on the number of start-ups in Sweden. We do this both for the total number of companies founded and the number of ventures in the tech industry. We test our hypotheses with a quantitative approach, performing a regression with a fixed effects model. The results of our research can show several things. For example, we found that there indeed is a significant impact of age structure on the number of (tech) company start-ups. We can see an M-shaped relationship between age and general entrepreneurship, meaning that while young adults and people closer to the retirement age affect the total number of companies founded positively, very young, middle aged and very old people affect it in a negative way. For the Swedish tech industry, we could show that founders here tend to be younger than overall, which is why we can observe a gradual negative relationship between age and entrepreneurship there

Die Arbeit untersucht, wie sich der demografische Wandel auf die öffentlichen Haushalte der deutschen Kommunen auswirkt. Zunächst werden die kommunalen Ausgaben und Einnahmen in sieben Altersgruppen der Bevölkerung aufgespaltet und unter Berücksichtigung verschiedener Ausgaben- und Einnahmekategorien auf ihre Alterssensitivität untersucht. Der verwendete Datensatz der 440 kreisfreien Städte und Landkreise unterscheidet sowohl nach Ausgaben- und Einnahmenseite der Budgets als auch nach Verwaltungs- und Vermögenshaushalten. Die ermittelten Altersstrukturprofile belegen die Jugendlastigkeit der Kommunalhaushalte. Danach werden die Befunde des Basisjahres 2005 in sechs verschiedenen Szenarien über einen Analysezeitraum von 20 Jahren projiziert, um die fiskalischen Effekte zu quantifizieren. Die rein demografischen Entwicklungen führen künftig zu Einnahmerückgängen, aber gleichzeitig zu größeren Potenzialen, um die Ausgaben zu senken. Verschiedene Trends und finanzpolitische Festlegungen reduzieren jedoch diese Effekte. Abschließend werden Anpassungsstrategien für die Kommunen diskutiert. / Demographic change will certainly have influence on the budgets of the German municipalities. Due to the division of public sector functions among different tiers in Germany’s federalism the municipalities serve mainly young generations with their public goods. Keeping this in mind, demographic trends will cause considerable effects on the communities’ budgets, especially in the Eastern part of Germany. Projecting the 440 German communes’ financial status of the basic year 2005 onto the year 2025, changing size and age structure of the German population will lower revenues as well as raise potentials to reduce expenditures even stronger. To take account of some special demographic trends and several fiscal regulations besides nothing but demographic ageing potential consolidation gains on the municipalities’ expenditures will be shrinking. Designing six different szenarios fiscal effects will be quantified. Finally, several strategies to deal with the fiscal consequences of demographic change will be discussed.

The resurgence of Texas' snook (Family Centropomidae) recreational fishery is coupled with an uncertainty as to what species occur in State waters, a limited understanding of life history, and habitat needs of its constituents. This study described species composition and early life history aspects of juvenile (< 100 mm SL) centropomids taken in bag seine collections in estuarine and freshwater habitats along the upper, middle, and lower coast of Texas during 2006 to 2010. Centropomus specimens (n = 548) captured from 41 locations across the Texas coast as well as congeners from Mexico (n = 24), Florida (n = 7), and Costa Rica (n = 3) were used in a genetics- and meristic-based determination of species composition, growth rates, range of hatching dates, geographic distribution, and habitat association. Genetic analyses of the mitochondrial DNA 16s ribosomal RNA gene and the mitochondrial control region (D - loop) validated the presence of smallscale fat snook (C. parallelus Poey, 1860, n = 333), common snook (C. undecimalis Bloch 1792, n = 212) and Mexican snook (C. poeyi Chavez, 1961, n = 3) in Texas, with the last of these validations representing the first known record of this species in Texas. AMOVA of 16s and D - loop sequences failed to detect genetic differentiation within Texas for C. parallelus and C. undecimalis. However, AMOVA for 16s and D - loop C. undecimalis sequences did yield significant genetic differences between Texas and Mexico against those from Florida and Costa Rica. Juvenile centropomids (< 100 mm SL) in Texas occupied backwater habitats with dissipated currents similar to those of Florida congeners (tidal sloughs, freshwater habitats, and structured shorelines). Coastal ranges of these species differed with C. parallelus taken from the Rio Grande to West Galveston Bay, whereas C. undecimalis was captured from the Rio Grande northward near Palacios. Three C. poeyi were captured at only two locations (Laguna Vista and Port Aransas). Daily growth rates varied between species and capture years, with these ranging from 0.22 to 0.97 mm d^-1. Analyses of hatch-date distribution suggest centropomids in Texas begin spawning in August and continue it through late September into mid-November.

Population models are very often used and considered useful in the policy-making process and for planning purposes. In this research I have tried to illuminate the problem of analysing population evolution in space by using three models which cover a wide spectrum of complementary methodologies: a The Hotell.ing-Puu model b A multiregional demographic model c A synergetic model Hotelling's work and Puu's later generalization have produced theoretical continuous models treating population growth and dispersal in a combined logistic growth and diffusion equation. The multiregional model is a discrete model based on the Markovian assumption which simulates the population evolution disaggregated by age and region. It is further assumed that this population is governed by a given pattern of growth and interregional mobility. The synergetic model is also a discrete model based on the Markovian assumption incorporating a probabilistic framework with causal structure. The quantitative description of the population dynamics is treated in terms of trend parameters, which are correlated in turn with demo-economic factors. / <p>Diss.

The aim of this diploma thesis is to evaluate the age and aging of the European population. At present, the aging process is affecting most countries in the Word. It occurs mainly in advanced countries, which includes most of the European countries. Population aging is linked to the process of the second demographic transition, which results in a change of the shares of the child´s and the old population. The main objective is to evaluate the age of individual regions (states) of Europe, according to various indicators, and thereafter to identify sub-regions in Europe according to the age of the population based on multidimensional statistical methods (point method, standardized variable method, factor and cluster analysis).
