The 2011 Industrial Relations Reform and Nominal Wage Adjustments in Greece

This study investigates nominal contractual base-wage adjustments in Greece associated with the 2011 industrial relations reform which re-defined the limits within which base wages could oscillate and allowed workers’ associations to negotiate for wages at the firm level. The assessment covers the period 2010-2013 and is based on information extracted from the universe of firm-level contracts signed in this period. We found that firm-level contracts increased dramatically shortly after the reform, now covering a larger pool of workers, especially in larger firms, and are associated with higher base-wage reductions in the post-reform period. At the firm level, wage reductions are higher when workers are represented by a workers’ association rather than a typical trade union. In addition, a heterogeneous effect is uncovered regarding the factors that shape base-wage adjustments (firm size, profitability, structure of bargaining body and aggregate unemployment) between new and traditional forms of workers’ representation in collective bargaining

Industrial Relations Reform, Firm-Level Bargaining and Nominal Wage Floors

We investigate the impact of the 2011 industrial relations reform in Greece that made firms with less than 50 employees eligible to participate to firm-level bargaining. Matching administrative contractual data with longitudinal firm-level data we identify firms affected and not affected by the reform. We find that during the first post-reform year, affected firms with less than 50 employees experienced a 4.8 per cent increase in the probability of firm-level contracting and a 12 per cent drop in wage floors relative to not affected firms. We also report estimates regarding the post-reform employment effect of firm-level bargaining

PALAEOCLIMATIC EVOLUTION IN LOUTRA ARIDEAS CAVE (ALMOPIA SPELEOPARK, MACEDONIA, N. GREECE) BY STABLE ISOTOPIC ANALYSIS OF FOSSIL BEAR BONES AND TEETH

Carbon and oxygen stable isotope values (δ13C, δ18O) were obtained from structural carbonate in the bioapatite of bear bones (Ursus ingressus) from Loutra Arideas cave, Almopia Speleopark, Macedonia, N. Greece. Samples of Late Pleistocene bear bones were studied for palaeoclimatic reconstruction of the area. The age range of the fossil layers is from 32ka BP to a maximum of 38ka BP. Generally, the palaeoclimatic proxy is correlated with literature data for climatic variations in the area during Late Pleistocene, whereas dietary behavior was investigated taking into account possible diagenetic processes that may have affected the carbonate matrix of the bones

Molecular profiling and genomic microarrays in prostate cancer

In the present review article a global approach regarding the usefulness of genomic microarrays in prostate cancer management, is attempted. Cancer is a multistep process of mutations in key regulatory genes and epigenetic alterations that result in loss of balanced gene expression. A complete knowledge of the interaction between the genetic variability of the neoformation (tumor profiling) and the genetic variability of the host (inherited genome profiling), will be able to determine the better strategy against the cancer and the less toxicity for the patient. Alterations in the sequence of the hormone binding domain of the androgen receptor as well as mutations in some genes, determine radioresistance and resistance or sensitivity to some chemotherapeutic drugs. New therapies using monoclonal antibodies directed against specific extracellular binding domains of some receptors are based on molecular alterations observed in tumors.В обзоре обсуждается целесообразность применения геномных микрочипов для выявления рака предстательной железы. Рак является многоэтапным процессом мутаций в ключевых регуляторных генах и эпигенетических изменений, приводящих к утрате сбалансированной экспрессии генов. Фундаментальные знания о взаимосвязи между генетической вариабельностью опухолевых клеток (молекулярном профиле опухоли) и генетической вариабельностью хозяина (наследуемый геномный профиль) позволит выбрать наилучшую стратегию противоопухолевой терапии при низкой токсичности таковой. Изменения последовательности гормонсвязывающего домена рецептора андрогена наряду с мутациями некоторых генов определяют устойчивость к лучевой терапии и устойчивость или чувствительность к ряду химиопрепаратов. Новые виды терапии с использованием моноклональных антител против специфичных внеклеточных связывающих доменов ряда рецепторов основаны на данных о молекулярных особенностях новообразований

Preliminary diagnostic reference levels for endoscopic retrograde cholangio-pancreatography in Greece

The main objective of this study was to determine the preliminary Diagnostic Reference Levels (DRLs) in terms of Kerma Area Product (KAP) and fluoroscopy time (Tf) during Endoscopic Retrograde Cholangio-Pancreatography (ERCP) procedures. Additionally, an investigation was conducted to explore the statistical relation between KAP and Tf. Data from a set of 200 randomly selected patients treated in 4 large hospitals in Greece (50 patients per hospital) were analyzed in order to obtain preliminary DRLs for KAP and Tf during therapeutic ERCP procedures. Non-parametric statistic tests were performed in order to determine a statistically significant relation between KAP and Tf. The resulting third quartiles for KAP and Tf for hospitals (A, B, C and D) were found as followed: KAPA = 10.7 Gy cm^2, TfA = 4.9 min; KAPB = 7.5 Gy cm^2, TfB = 5.0 min; KAPC = 19.0 Gy cm^2, TfC = 7.3 min; KAPD = 52.4 Gy cm^2, TfD = 15.8 min. The third quartiles, calculated for the total 200 cases sample, are: KAP = 18.8 Gy cm^2 and Tf = 8.2 min. For 3 out of 4 hospitals and for the total sample, p-values of statistical indices (correlation of KAP and Tf) are less than 0.001, while for the Hospital A p-values are ranging from 0.07 to 0.08. Using curve fitting, we finally determine that the relation of Tf and KAP is deriving from a power equation (KAP = Tf^1.282) with R^2 = 0.85. The suggested Preliminary DRLs (deriving from the third quartiles of the total sample) for Greece are: KAP = 19 Gy cm^2 and Tf = 8 min, while the relation between KAP and Tf is efficiently described by a power equatio

Electrocardiographic Changes in a Patient With Pulmonary Embolism and Septic Shock

Various electrocardiography (ECG) abnormalities have been reported in patients who present with pulmonary embolism (PE). Severe sepsis is also associated with ECG changes that may mimic ST elevation myocardial infarction. We report a case of an elderly patient with PE and septic shock associated with striking ECG changes

The short-term impact of the 2020 pandemic lockdown on employment in Greece

This paper analyzes the short-term employment impact of the COVID-19 lockdown in Greece during the first few months following the pandemic onset. During the initial lockdown period, aggregate employment was lower by almost 9 percentage points than it would have been expected based on pre-pandemic employment trends. However, due to a government intervention that prohibited layoffs, this was not due to higher separation rates. The overall short-term employment impact was due to lower hiring rates. To uncover the mechanism behind this, we use a difference-in-differences framework, and show that tourism-related activities, which are exposed to seasonal variation, had significantly lower employment entry rates in the months following the pandemic onset compared to non-tourism activities. Our results highlight the relevance of the timing of unanticipated shocks in economies with strong seasonal patterns, and the relative effectiveness of policy interventions to partly absorb the consequences of such shocks
