Resumen

Many observers, and many investors, believe that young people are especially likely to produce the most successful new firms. Integrating administrative data on firms, workers, and owners, we study start-ups systematically in the United States and find that successful entrepreneurs are middle-aged, not young. The mean age at founding for the 1-in-1,000 fastest growing new ventures is 45.0. The findings are similar when considering high-technology sectors, entrepreneurial hubs, and successful firm exits. Prior experience in the specific industry predicts much greater rates of entrepreneurial success. These findings strongly reject common hypotheses that emphasize youth as a key trait of successful entrepreneurs. (JEL G24, J14, L26, M13, O31)

Resumen

This article assesses the empirical relationship between per capita income growth fluctuations and the age-structured human capital variations across four groups of geographically clustered developed and developing countries from spatial perspective. We estimate a spatial Vector Autoregressive (VAR) model of income dynamics where the distance between countries is defined on relational space based on their similarity in appropriation tendency of human capital in the production processes. These distances are computed using a newly developed human capital data set which fully characterizes the demographic structure of human capital, and thus underlines the joint relevance of demography and human capital in economic growth. Spatial effects on growth interdependence and complementarity are then explored with respect to the proposed distance metrics. Our results imply that significant cross-country growth interdependence based on human capital distances exists among defined country groups suggesting the need for a cooperative policy programme among them. We also find that the relationship between economic growth and human capital is highly nonlinear as a function of the proposed human capital distance.

Resumen

Prostate cancer is the most commonly diagnosed malignancy among men, but few genetic factors that drive prostate cancer initiation have been identified. The WD repeat domain 77 (Wdr77) protein is essential for cellular proliferation when it localizes in the cytoplasm of epithelial cells at the early stage of prostate development. In the adult prostate, it is transported into the nucleus and functions as a co-regulator of the androgen receptor to promote cellular differentiation and prostate function. This developmental process is reversed during prostate tumorigenesis i.e., Wdr77 is translocated from the nucleus into the cytoplasm to drive proliferation of prostate cancer cells. In this study, we used in vivo genetic studies to investigate the role of Wdr77 in prostate tumorigenesis. We found that prostate-specific deletion of Wdr77 abolished prostate tumor initiation induced by loss of the tumor suppressor Pten. Mechanistically, Wdr77 ablation inhibited E2F3 activation and enhanced TGFb signaling, leading to attenuated cellular proliferation induced by loss of Pten. These findings establish an essential role of Wdr77 for prostate tumor initiation.

Resumen

The relationship between a firm’s size, age and proportional growth rate is examined using multiple samples of South African firm-level data from the early to mid-2000s. The foundation of this study is Gibrat’s Law of Proportionate Effect (Gibrat, 1931), which states that a firm’s proportional growth rate is independent of its absolute size at the start of a given period. It is assumed that firm growth follows a random walk and, therefore, should not be affected by firm size. An implication of Gibrat’s Law of Proportionate Effect is that the firm size distribution is lognormal. However, based on both empirical and theoretical literature, this theory of firm growth has fallen out of favour and been replaced by the proposal that there is an inverse relationship between a firm’s proportional growth rate and both its size and age. Two questions are evaluated in this research using the samples of South African firms. The first is whether the firm size distribution is lognormal. If this is not the case then Gibrat’s Law of Proportionate Effect can be rejected. However, this approach cannot confirm that Gibrat’s theory is valid and will, therefore, be referred to in this paper as a partial test. It was shown that the log firm size distribution was not normal, but rather right-skewed with a Pareto distribution characterising the upper tail. Consequently, Gibrat’s Law of Proportionate Effect was rejected for the datasets of South African firms. This evidence is largely observational and does not explicitly assess the relationship between proportional growth rates and firm size. Therefore, the second question is whether Gibrat’s Law of Proportionate Effect holds. This was investigated by testing conditions derived from Gibrat’s Law of Proportionate Effect, the results of which can lead to either the rejection or acceptance of this proposition. This study extends Gibrat’s research in order to determine the relationship between firm age and proportional growth. Statistical methods, such as Ordinary Least Squares regressions, considering only firms that survived the period under consideration, were used. The results revealed that Gibrat’s Law of Proportionate Effect was invalid and there was a systematic tendency for the smaller, younger South African firms in the datasets to grow proportionally faster than the larger, older firms. This finding supports the view that firm growth is not entirely random.

Resumen

This report presents an analysis of a partial differential equation, resulting from population model with age structure. The existence and uniqueness of a solution to the equation are proved. We look at stability of the solution. The asymptotic behaviour of the solution is treated. The report also contains a section about the connection between the solution to the age structure population model and a simple model without age structure.

Resumen

Nearly half of the known species of sharks in the world live in the deep sea, yet little is known of the biology or life history of these important predators of the deep. Fishing effort for deep-water sharks, both targeted and incidental, has been increasing worldwide over the last few decades. However, in most cases the impact of this harvest is unknown due to the paucity in landings data and the lack of stock assessments for these species. This research was conducted to provide some of the basic life history information needed to improve the understanding and properly manage deep-water sharks. Specifically, information is presented herein on age determination using dorsal fin spines; the potential for radiometric age validation using dorsal fin spines; the age, growth, and reproductive biology of Squalus mitsukurii from Hawaiian waters; and the reproductive biology and embryonic development of Centrophorus cf. niaukang and Etmopterus princeps.;Dorsal fin spines offer an alternate structure for age determination in phalacanthous chondrichthyans. In this study, I sought to identify optimal methods of age determination using dorsal fin spines of 14 species of squaliform sharks and two species of holocephalans. Growth bands can be found in three zones of the fin spine: on the enamel cap (if present), at the base of the whole spine, or in the inner dentine layer. Each of these three methods was applied to fin spines from these 16 species. Results of each method are compared and discussed, with an optimal aging method suggested for each species.;Radiometric methods have been used to validate age estimates from teleost otoliths, shark vertebrae, and coral skeletons. The radioisotopes 210Pb and 226Ra were ineffective for age determination of dorsal fin spines, possibly due to a violation of the assumption of constant isotopic uptake, or conversely the spine may not act as a closed system.;A study of age, growth and reproductive biology of Squalus mitsukurii was conducted near Oahu, Hawaii. Age estimates ranged from 3 to 26 years for females and 6 to 23 years for males. Growth parameters estimated with multiple growth models indicated that this a K-selected species, characterized by high longevity, late maturity, and slow growth. Observed fecundity also indicated that reproductive output is low for this species.;A study of embryonic development in Centrophorus cf. niaukang and Etmopterus princeps indicated that the process of embryogenesis results in a range in organic matter depletion from the time of fertilization to parturition. Centrophorus cf. niaukang embryos showed a reduction of 19.5% in organic matter, while E. princeps embryos showed a reduction of 7.8% in organic matter over the course of embryonic development. These results indicate that at least one of these species may be matrotrophic. Observed fecundity and maturity ogives are also presented for each species.;This study on age determination, growth, and reproductive biology of several species of deep-water sharks and holocephalans indicated that these are K-selected species. Future harvest of these species should proceed with caution, as they are prone to overexploitation and localized depletion.

Resumen

We construct a new dataset of inequality in educational attainment by age and sex at the global level. The comparison of education inequality measures across age groups allows us to assess the effect of inter-generational education attainment trends on economic growth. Our results indicate that countries which are able to reduce the inequality of educational attainment of young cohorts over time tend to have higher growth rates of income per capita. This effect is additional to that implied by the accumulation of human capital and implies that policies aiming at providing broad-based access to schooling have returns in terms of economic growth that go beyond those achieved by increasing average educational attainment.

Resumen

The periodicity of formation of growth increments in the otoliths of South African sparids was validated by the oxytetracycline labelling technique. Intramuscular injections of oxytetracycline at a dosage of 250mg/kg marked the otoliths of laboratory held juvenile sparids, while a dosage range of 50 - 100mg/kg oxytetracycline, injected intramuscularly, marked adult sparids in the field. Laboratory held, larval sparid otoliths were marked by immersion for 24hrs a solution of 100-150mg/l alizarin complexone. Both daily (microstructural) and annual (macrostructural) growth increments were identified in the otoliths. The micro incremental pattern of deposition in the sparid otoliths conformed to the general pattern of otolith structure. Sparid otoliths consisted of a central opaque nucleus composed of multiple primordia. surrounding this nucleus were daily increments which decreased in width as the distance from the nucleus increased. Both check rings and subdaily increments were visible throughout the otolith. Minor environmental changes did not affect micro incremental deposition. Narrow opaque and wide hyaline annual growth zones were identified in sectioned sparid otoliths. Scanning electron microscope analysis of the annual growth zones revealed that microincrements within the opaque zone were narrowly spaced with prominent discontinuous phases. This resulted in the greater optical density and higher protein content of the zone. The hyaline zone was composed of widely spaced daily increments with prominent incremental phases accounting for the translucent nature of this zone. Opaque zone formation in the otoliths of many South African sparids was found to occur primarily during periods of reproductive activity and was shown to be indicative of slow otolith growth. The hyaline zone was formed after the spawning season, representative of fast otolith growth. The results of this study have resolved much of the controversy surrounding the rate of growth and time of formation of the opaque and hyaline growth zones in South African sparid otoliths.

Resumen

We assess empirically the role played by prospective ageing measures as a predictor of income growth in Europe. We show that prospective ageing measures which move beyond chronological age and incorporate changes in life expectancy are able to explain better the recent long-run growth experience of European economies. The improvement in explanatory power of prospective ageing indicators as compared to standard measures based on chronological age is particularly relevant for long-run economic growth horizons.

Resumen

The relationship between population changes and economic growth has been debated since Malthus. Initially focusing on population growth, the notion of demographic dividend has shifted the attention to changes in age structures with an assumed window of opportunity that opens when falling birth rates lead to a relatively higher proportion of the working-age population. This has become the dominant paradigm in the field of population and development, and an advocacy tool for highlighting the benefits of family planning and fertility decline. While this view acknowledges that the dividend can only be realized if associated with investments in human capital, its causal trigger is still seen in exogenous fertility decline. In contrast, unified growth theory has established human capital as a trigger of both demographic transition and economic growth. We assess the relative importance of changing age structure and increasing human capital for economic growth for a panel of 165 countries during the time period of 1980-2015. The results show a clear dominance of improving education over age structure and give evidence that the demographic dividend is driven by human capital. Declining youth dependency ratios even show negative impacts on income growth when combined with low education. Based on a multidimensional understanding of demography that considers education in addition to age, and with a view to the additional effects of education on health and general resilience, we conclude that the true demographic dividend is a human capital dividend. Global population policies should thus focus on strengthening the human resource base for sustainable development.

Resumen

The paper presents some results of the analysis of the Life Cycle Deficit (LCD) of the population aged 60 and over, based on the data frame of the National Transfer Accounts (NTA) for 2019. Based on age profiles of aggregate data is attested that the LCD of the elderly population in Moldova is about 41% of the LCD of all ages. The primary sources of livelihood for the elderly are not so much income from work but public transfers (payments for social programs, including pensions, healthcare and social services) – 37.8%. Redistribution of private asset-based reallocations plays a fairly significant role in financing the consumption of older people (30.7% of consumption). Along with advancing age, the economic activity of the population inevitably decreases. During the pre-retirement period, the self-employment labor income remains to have a special role in supplementing incomes and becoming the only source after age 75. People aged 60-75 continue to be donors in intergenerational transfers. Only after the age of 75+, do the elderly become recipients of private transfers. A gender characteristic is that older women remain the main beneficiaries of private transfers due to higher life expectancy. The aging of the population will accelerate in the coming decades, according to forecasts. Therefore, the share of the economically dependent population and the LCD will increase. More vigorous policy efforts are required to improve productivity and increase the potential of the working-age population, including by ensuring active and healthy aging and social security for the elderly.

Resumen

Abstract Active fluids are often is known as the aqueous suspensions of self-propelled elements such as bacteria, algae, or sperm cells, which their properties fundamentally differ from conventional fluids. Active fluids exhibit remarkable physical manifestations over a wide range of scales, from time-dependent microscopic diffusion to the large-scale colonization of aqueous spaces. Properties of active fluids depend on the behavior of microbial suspensions, among which motility plays a crucial role. In this work, we focus on the effect of microbial growth and aging on microorganism motility. Hence, the motility behavior of cyanobacterium Synechocystis sp. CPCC 534, and its relationship with aging were investigated in a closed microfluidic chip. The growth of Synechocystis cultures was followed from the lag phase, through exponential and linear growth up to the stationary phase. Culture samples were periodically examined; cell populations were measured by spectroscopy technique and cell trajectories were tracked by video-microscopy.

Resumen

The Far East is a region that has been developing more slowly than other regions of the Russian Federation for a long time. The problems of the development of the region are natural and geographical - the severity of the climate over a large area of the region, remoteness from the federal center, infrastructural - the poor development of intra-regional ties, problems with transport, social - low (compared to the average Russian indicators) provision of residents with medical, educational and other public services. The weak development of industry, low GRP and, as a result, the high dependence of the budgets of the Far Eastern subjects of the Federation on transfers from the federal budget are serious problems of the Far East. In order to develop the region, the state program of the Russian Federation «Socio-economic development of the Far Eastern Federal District» has been developed. The main goals of the state program are: the formation and development of territories of advanced socio-economic development with favorable conditions for attracting investments in the Far Eastern Federal District and the development of economic growth centers of the constituent entities of the Russian Federation that are part of the Far Eastern Federal District, and some others. The plans for the social development of economic growth centers, developed by the regions of the Far East and financed to a large extent from the federal budget, can play a key role in this.

Resumen

Urban planners, politicians and citizens need comprehensive and clear information in order to conduct or get involved into successful evidence based planning and policy making. The objective to improve the quality of planning outcomes both at the local and regional level necessitates in creation of design mechanisms which could help planners verify and support their approach with quantitative analyses and simulation tools. While this sort of problems has already been explored for a while, with an abundant literature on the topic, there still remains a lot to say, especially when it comes to evaluation of plans, such as local plans of urban development, general plans, studies for the municipalities or larger, inter-municipal associations. Along with the implementation of INSPIRE Directive in Europe, data for these analyses, so far patchy and incomplete, becomes slowly but progressively available. The use of quantitative analyses may refer to several aspects of physical form, such as connectivity, continuity of ecological systems, conciseness of built structures and urban boundary, analyses of the morphology of urban tissue, etc. Completed with the qualitative description and enriched with the socio-cultural preconditions assessment they may give a comprehensive picture both of the current and the planned state. The current paper presents an experience of mapping typologies of residential structures in the settlements neighbouring Lodz, Poland, with the objective to assess the existing densities and planned development capacities against the backdrop of demographic dynamics in these region.References Berghauser-Pont, M. and Haupt, P.

Resumen

Contemporary processes of urbanization have outpaced the traditional notion of city. Connectivity has become a distinctive characteristic of urban spaces, so that networked cities don’t rely anymore on continuous urbanized areas, but on connections that rarely leave a direct spatial footprint. The new spatial structure of urban areas include greater inter-penetration of built-up and open spaces, and the emergence of urban enclaves, which can be spatially isolated despite being functionally connected to a city. In order to study these enclaves and their impact on urban form, a sample of 47 Spanish functional urban areas was examined, ranging from 36,000 to 6.0 million inhabitants. Land use polygons provided by SIOSE were grouped into three main categories (residential, non-residential and urban infrastructure) and cross-matched with functional urban areas defined by AUDES (an iterative method than combines morphological and functional criteria) in order to calculate compactness proximity index, gross and net density. Factors that influence urban compactness were identified: most northern and some coastal urban areas display a low compactness which can be attributed to orographic conditions; bigger cities tend to display high compactness, but smaller ones display a great diversity of values, from the highest to the lowest. A further analysis of small and intermediate cities helped to identify two complementary mechanisms of urban growth, spatial expansion of core areas and functional integration of peripheral nuclei, whose ocurrence in different proportions can explain the variation of compactness in the studied sample.

Resumen

Trends and differentials in the age at first birth are well-documented (FP-20-06). Given shifts and variation in completed family size (FP-20-04), it is also important to look at the age of last birth – that is, when do women stop having children – which has received very little attention. This profile investigates the median age at last birth among women at the end of their childbearing years, at 45-49 years old. Using the 2015-2019 cycles of the National Survey of Growth, this profile investigates the median age at last birth for mothers aged 45-49 by race/ethnicity, completed education, parity, and age at first birth.
