On the basis of largely neglected Hungarian sources and Austrian archival material, this article argues that, with the emergence of a “Hungarian factor” in Habsburg foreign policy after 1867, policy towards Serbia increasingly relied on the Monarchy’s personal hold over Prince Milan Obrenovi?. This strategy in turn can be seen as part of a Hungarian surrogate “imperialism,” through which the Habsburg Monarchy would enhance Hungary’s security through hegemony in the Danubian basin. The policy was eventually consolidated in 1880–1881 by a series of treaties which made Serbia an economic and political satellite of the Monarchy, but the linch-pin of the structure remained Milan Obrenovi?. Milan, however, proved an imperfect instrument since he loathed Serbia, was unpopular because of his obvious subservience to Austro-Hungarian interests, and longed for the fleshpots of Western Europe. The article suggests that such a “personal policy” was increasingly unlikely to succeed after the granting of a more liberal constitution to Serbia in 1869, and as the country became politically a more complex society. The article thus demonstrates the essentially futile nature of this exercise in personal diplomacy, and the inherent impossibility of controlling an entire society through the person of its ruler.  相似文献

Background.?Saliva collection is an easy, non-invasive method to measure hormones.

Methods.?Two studies were performed. In the first, a convenience sample of 1454 males who had submitted saliva for salivary testosterone measurements were studied. In the second study, we intensively studied symptoms and measurements of total testosterone, free testosterone symptoms and measurements of total testosterone, free testosterone and bioavailable testosterone in relationship to salivary testosterone in 127 men. A secondary endpoint was to examine the relationship of salivary testosterone to hypogonadal symptoms in the ADAM and AMS questionnaires.

Results.?In the first study, we have shown that salivary testosterone, measured in 1454 males aged 20 to 89 years, declines by 47% over the lifespan. In the second study, salivary testosterone was strongly correlated with bioavailable testosterone (p < 0.000001) calculated free testosterone (p < 0.00001) and total testosterone (p < 0.002). Salivary testosterone was significantly related to hypogonadal symptoms on the St. Louis University ADAM questionnaire and the Aging Male Survey.

Conclusions.?These studies support the use of salivary testosterone as an acceptable assay for screening for hypogonadism. Salivary testosterone is not a better assay than other measures to diagnose hypogonadism.  相似文献

Despite underlying regularities in the age profile of migration, there is mounting evidence of cross‐national variations in the ages at which migration occurs. Explanations for these differences have variously been sought by reference to cultural, social, and economic factors, and through analysis of reasons for moving. There is also a growing body of work linking migration events to particular transitions in the life course. We set out a conceptual framework that links contextual factors to the age structure of migration through life‐course transitions that act as proximate determinants of the age at migration. We propose metrics to capture the prevalence, timing, and spread of four key life‐course transitions: education completion, labor force entry, union formation, and first childbearing. We then seek to quantitatively establish the link between these indicators and the age and intensity of internal migration at its peak for a global sample of 27 countries. Correlation and factor analysis reveal substantial diversity in the timing and spread of transitions to adult roles, and show that cross‐national differences in the age profile of migration closely parallel variations in the age structure of the life course for over two‐thirds of countries. Migration age profiles are aligned with transitions to adulthood for both sexes but most strongly among women.  相似文献

ABSTRACT

Public relations scholars continue to debate “whether persuasion is a legitimate public relations function” (Edgett, 2002 Edgett, R. (2002). Toward an ethical framework for advocacy in public relations. Journal of Public Relations Research, 14, 126.[Taylor & Francis Online] [Google Scholar], p. 1). Their ambivalence toward persuasion has deep roots in the tangled lineage of Peitho, the Greek goddess of persuasion. The purpose of this article is to chart the goddess Peitho's contradictory history in classical Greek literature and art; and to study how the Greeks resolved that ambiguity. Ultimately, the Greeks determined that Peitho, at her best, was honest, respectful of others, and mindful of community wellbeing. The Greeks’ resolution of Peitho's nature ideally holds lessons for the troubled status of persuasion within modern public relations.  相似文献

We study a continuous‐time principal–agent model in which a risk‐neutral agent with limited liability must exert unobservable effort to reduce the likelihood of large but relatively infrequent losses. Firm size can be decreased at no cost or increased subject to adjustment costs. In the optimal contract, investment takes place only if a long enough period of time elapses with no losses occurring. Then, if good performance continues, the agent is paid. As soon as a loss occurs, payments to the agent are suspended, and so is investment if further losses occur. Accumulated bad performance leads to downsizing. We derive explicit formulae for the dynamics of firm size and its asymptotic growth rate, and we provide conditions under which firm size eventually goes to zero or grows without bounds.  相似文献
