Applying an investment perspective to higher education, the paper presents detailed empirical evidence on the rate of return to higher education and its determinants. Employing a sample of 17,180 higher education graduates derived from the German Labor Force Survey 2004, we show considerable variation in the rates of return to higher education across the different subjects, with some subjects on average not representing attractive private investments from an economic point of view. We find that the decision what to study is worth several hundred thousand Euros. Applying regression analysis, we find gender- and degree-specific return advantages only in certain subjects. Comparing the return of an investment in higher education and the production cost of higher education, we show that more expensive subjects (apart from Medicine) yield a lower return. When considering the cost of study, the overall order of attractiveness of the different forms of education remains stable, but the investment in further subjects is no longer clearly attractive. Keywords: Returns to Education, Human Capital, Higher Education Earnings Capacity.
Jan Snyman papers
(2007)
Biographical history and context: Professor Jan Snyman spent most of his life researching the lesser known and marginalised San languages of Botswana and South West Africa (now Namibia). Together with O. Kohler, E. Westphal and A. Traill, he pioneered linguistic studies on these endangered languages of Africa. He contributed significantly in collection of the data that helped classify and understand the grammar of San languages. Snyman also wrote several grammars in the form of monographs and notes on these languages. By the time he died, in 2002, a draft for the Tshwaa and Kua languages had been completed. Content: Linguistic, phonetics and orthography research materials including fonts for phonetic languages. Covering dates: 1967-2000
This paper documents the experiences of assurance evaluation during the early stage of a large software development project. This project researches, contracts and integrates privacy-respecting software to business environments. While assurance evaluation with ISO 15408 Common Criteria (CC) within the certification schemes is done after a system has been completed, our approach executes evaluation during the early phases of the software life cycle. The promise is to increase quality and to reduce testing and fault removal costs for later phases of the development process. First results from the still-ongoing project suggests that the Common Criteria can define a framework for assurance evaluation in ongoing development projects.
Compositionality
(2007)
This article generalizes Schwinger’s mechanism for particles production in the arbitrary finite field volume. McLerran-Venugopolan(MV) model and iterative solution of DGLAP equation in the double leading log approximation for small x gluon distribution function were used to derive the new formula for initial chromofield energy density. This initial chromofield energy is distributed among color neutral clusters or strings of different length. This strings are stretched by receding nucleus. From the proposed mechanism of string fragmentation or color field decay based on exact solution of Dirac equation in the different finite volume, the new formulae for esimated baryon kinetic energy loss and rapidity spectrum of produced partons were derived.
Polabian accentuation
(2007)
From a synchronic point of view, the accentuation of Late Polabian has been clarified by Trubetzkoy (1929) and Olesch (1973, 1974). The stress fell on the last full vowel of a word form, which was found either in the final or in the penulti-mate syllable. In the latter instance, the final syllable contained a reduced vowel. This rule was challenged by Kurylowicz (1955), who maintained that the stress was fixed on the initial syllable of the word. The latter theory has the advantage of accounting for the absence of reduced vowels in initial syllables.
Winter's law again
(2007)
Since I discussed the scholarly literature on Winter’s law twenty years ago (1988), several important articles on the subject have appeared (Young 1990, Campanile 1994, Matasovic 1995, Derksen 2002, Dybo 2002, Patri 2005, Derksen 2007). As the law evidently continues to be controversial, it is important to look into the nature of the evidence and counter-evidence which is adduced. It appears that doubts about Winter’s law are largely the result of four types of misunderstanding.
Nestling growth and development studies have been a topic of interest for a greater part of the last century (Sutton 1935, Walkinshaw 1948) and continue to be of interest today. This is not surprising since studies on nestling growth can provide a wealth of biological information that has larger implications for avian management and conservation. Despite this history of studying nestling development, basic information is still limited or absent for many species. Many questions remain unanswered, and contradictory conclusions are often found in the literature (Starck and Ricklefs 1998a). Therefore, much information on aging and development can still be gained from studying the development patterns of similar species and from comparative studies, across avian orders (Minea et al. 1982, Saunders and Hansen 1989, Carsson and Hörnfeldt 1993). Additionally, nestling growth studies can yield insight into the effects of different nesting strategies on productivity (O’Connor 1978), as well as the impacts of parental effort and environmental variables on fitness (Ross 1980, Ricklefs and Peters 1981, Magrath 1991). Since low reproductive success may play a significant role in the declines of many North American passerines (Sherry and Holmes 1992, Ballard et al. 2003), a better understanding of the factors that influence reproductive success is a vital component of avian conservation (Martin 1992). Data on nestling aging can be used to improve nest survival estimates (Dinsmore 2002, Nur et al. 2004), providing information that can be used to more precisely age nests (Pinkowski 1975, Podlesack and Blem 2002), (Jones and Geupel 2007). Indeed, the relatively short time period young spend developing in the nest is a critical part of a bird’s life cycle and a nestling’s developmental path can affect its survival to independence, its survival as an adult, and its future reproductive success.
When Angela Merkel arrives at the United Nations for the opening of the 62nd session of the General Assembly on Tuesday [25 September] to deliver her first address as German chancellor she will be very well received. Just after two years in power she has already become something like a foreign policy legend...
