Higoumenakis' sign in the diagnosis of congenital syphilis in anthropological specimens

Higoumenakis' sign (HS) is a diagnostic criterion referring to the enlargement of the sternal end of the (right) clavicle, frequently observed in patients with late congenital syphilis. Although indexed for several years in clinical medicine textbooks, it has not been extensively applied for the diagnosis of congenital syphilis among anthropological specimens. This is highly significant, since the other major palaeopathology findings refer almost exclusively to the skull and diagnosis thus becomes difficult if only peripheral skeletal remains are available for evaluation. The potential effectiveness of the proposed use of HS as a marker of syphilis in anthropology appears adequate, since descriptions very similar to that of HS have been reported for certain findings, although no attempt has been made to correlate them with the presence of the disease. Higoumenakis himself originally observed this sign in 86% of his patients with congenital syphilis, and this report was subsequently verified by other independent researchers. His attempt to explain the pathophysiology of the sign and its localisation, on the basis of anatomical, biological, and mechanical reasons, however, has been questioned. On the other hand, the application of the remaining markers of congenital syphilis is also problematic, due to sensitivity and/or specificity limitations, and other signs may not be detected due to inability to retain soft tissue samples in anthropological populations and a lack of reliable techniques for treponematous DNA amplification in such old samples. Thus, the fact that the onset of any of the signs of syphilis is not a constant finding justifies the authors' suggestion that HS should be checked for in any available anthropological specimen, because it is highly indicative of possible infection by Treponema pallidum. © 2011 Elsevier Ltd

Online and mobile customer behaviour: a critical evaluation of grounded theory studies

With the rapid increase of electronic and mobile commerce over the last few years, the academic literature on online and mobile customer behaviour has been fairly plentiful with a great deal of quantitative studies testing variations of existing customer behaviour theories. However, little attention has been given to qualitative studies in the field, which seek to explore new aspects of online or mobile customer behaviour, adding to existing theories or even creating new ones. Thus, the purpose of the present paper is to critically evaluate studies employing Grounded Theory, a method commonly used for theory building in qualitative social research. Nine studies were identified examining online or mobile customer behaviour under this approach, providing theories based on emerging categories. Results of their studies seem to be very similar to existing customer behaviour theories, occasionally adding new categories to the existing theory nomenclature. Studies presented weaknesses regarding the accurate methodological conduct of Grounded Theory and the process of generating theory, attributed predominantly to methodological, verification and reporting bias. Nevertheless, the main advantage of Grounded Theory studies remains the generation of theory that can be applied in practice, reinforced by the presentation of conceptual prospects for testing new variables in quantitative studies. Overall, the contribution of Grounded Theory studies to online and mobile customer behaviour research should be based on more rigorous methodology and aim to challenge rather than confirm existing theories with the purpose of advancing knowledge in the field

The International Monetary Fund, the World Bank and Financial Stability: The Case of Russian and East Asian Financial Crises

The role of the International Monetary Fund (IMF) and the World Bank (WB) in providing financial stability to countries with financial problems has received conflicting views from different social and political groups. The purpose of this paper is to examine whether these two international organizations provide financial stability by focusing on the case of the Russian and East Asian financial crises. After a comprehensive analysis (graphs, tables and statistical regression models), the researchers found that the support of both the IMF and the WB was mostly without success in these two crises; thus promoting financial instability. This finding comes from both a descriptive analysis of financial stability in terms of unemployment, inflation and changes in GDP and GDP per capita and quantitative calculations by performing multiple linear regressions in PASW 18.0 with certain indicators [GDP Annual growth rate, Interest rate spread (lending rate minus deposit rate, %), Inflation, GDP deflator (annual %), Annual industrial value and GINI Index]. The intervention of these international organizations appears to have been followed by unemployment and inflation rises, as a result of their financial policies. These results provide important incentives for international policy changes in dealing with financial crises, emphasizing the importance for less destabilizing practices

Factors affecting customers’ decision for taking out bank loans: a case of Greek customers

The concept of loyalty has received much consideration from both academics and practitioners in various industries and is a predominant research topic in the banking industry. Identifying the factors that affect customers’ decision to take out a loan from a particular bank has become an essential asset for many banks in their effort to attract new customers and to maintain existing ones. The purpose of the present study is to identify factors that influence Greek customers’ decision to take out a loan from commercial banks. A number of variables (demographics, service quality and satisfaction) have been examined as potential factors influencing customers’ decision to take out a loan. A randomly selected sample of Greek citizens (n=277) was chosen in order to test our hypotheses. A questionnaire with self-determined scales was created after ensuring the instrument’s validity through confirmatory factor analysis. Logistic regression results show that personal marital status, customer service, shop design and interest rates are the most significant predictors of taking loans. Several managerial implications suggest bank managers should focus on giving loans to single individuals as well as change their interest rates policies by decreasing rates for all kinds of loans, especially housing loans
