Since 2007 farmgate milk prices in EU have become much more volatile and their seasonal pattern has stopped being so explicit. The purpose of this research is to test the hypothesis that seasonality still plays an important role in shaping farmgate milk prices in EU while its amplitude decreases together with the growing integration of the EU milk market with the global market. The aforementioned issues are investigated using Census X-12 procedure of price decomposition and panel random effects model. The results indicate that after 2007 the role of seasonality in determining EU farmgate milk prices has significantly decreased which partially results from the higher integration of the EU milk market with the global market. Nevertheless, seasonality remains an important factor determining the farmgate milk prices in EU. It can be expected that with the further globalization of the milk market, the significance of seasonality in determining farmgate milk prices in EU will be diminishing.

Breast (BCa) and gynecological (GCa) cancers constitute a group of female neoplasms that has a worldwide significant contribution to cancer morbidity and mortality. Evidence suggests that polymorphisms influencing miRNA function can provide useful information towards predicting the risk of female neoplasms. Inconsistent findings in the literature should be detected and resolved to facilitate the genetic screening of miRNA polymorphisms, even during childhood or adolescence, and their use as predictors of future malignancies. This study represents a comprehensive systematic review and meta-analysis of the association between miRNA polymorphisms and the risk of female neoplasms. Meta-analysis was performed by pooling odds-ratios (ORs) and generalized ORs while using a random-effects model for 15 miRNA polymorphisms. The results suggest that miR-146a rs2910164 is implicated in the susceptibility to GCa. Moreover, miR-196a2 rs11614913-T had a moderate protective effect against female neoplasms, especially GCa, in Asians but not in Caucasians. MiR-27a rs895819-G might pose a protective effect against BCa among Caucasians. MiR-499 rs3746444-C may slightly increase the risk of female neoplasms, especially BCa. MiR-124 rs531564-G may be associated with a lower risk of female neoplasms. The current evidences do not support the association of the remaining polymorphisms and the risk of female neoplasms.

Purpose The research studies the role of contextual moderating variables on the relationship between person-oriented leadership behaviors (POLBs) and team performance. The authors claim that the varying effect sizes between POLBs and team performance are large because of the context the team is functioning in. Therefore, based on the framework of Johns (2006), this paper aims to investigate the moderating role of the relevant demographic (leader gender), social (in-group collectivism and team size), task (skill differentiation) and methodological (common method bias and the rater of the team performance) contextual variables in the study. Design/methodology/approach The authors accumulated evidence from 48 independent primary studies (N team = 4,276) to run the meta-analytic analyses. The authors followed the procedures described by Schmidt and Hunter (2015). For the categorical moderators, the analyzes were aided by the Hunter–Schmidt meta-analysis programs (2.0) (Schmidt and Le, 2014), which is an interactive software using a random-effects model. In the analyzes for the continuous moderators, the authors used Lipsey and Wilson’s (2001) statistical package for the social sciences macros and run meta-regressions using a random-effects model with unrestricted maximum likelihood. Findings The results indicate that the relationship weakens when female leaders exhibit these behaviors and when the team size increases. On the other hand, in-group collectivism strengthens the relationship. The study also found that the common method bias and the assessment method of the team performance are significant moderators altering the relationship. Practical implications The study highlights the perceptual differences and biases based on leader gender. Acknowledging these biases may help practitioners to appreciate the female qualities in leadership and decrease the undervaluation of female effectiveness. To create high-performing teams, leaders in high in-group collectivist countries are expected to develop a family feeling in the team by showing their concern for personal issues and build close interpersonal relationships. Researchers should use multiple sources to assess the predictor and criterion variables and also opt for more objective assessment methods for team performance. Originality/value With this study, the authors follow a substantively different perspective compared to the past meta-analytic reviews on this relationship. Rather than testing the inquiry whether there is a relationship between the two variables, the authors specifically focus on the role of contextual moderating variables. Several researchers have acknowledged that contextual considerations are critical in leadership-team performance research. Nevertheless, the body of research remains to be not cohesive. Thus, the study answers a call in the leadership area for a more context-based and cohesive understanding of the effects of leadership on team performance.

The aim of this chapter is to investigate shadow economy on an EU-27 and Turkey basis. For this purpose, firstly the definition, causes\ and consequences of shadow economy together with its relationship with tax evasion are discussed. In addition, the causes of shadow economy are examined for EU-27 during the period 2003-2012. It was done both statistically and empirically by employing scatter plot diagrams and the random effects model. While empirical findings confirm the effects of taxes, income level, trade and population on the shadow economy, statistical findings mention the effects of governance related indicators. Another main finding of this chapter is about Turkey. Accordingly, shadow economy in Turkey is observed to be higher than in the EU-27 and taking into consideration the comparative statistical findings about the causes of shadow economy, the main reasons of shadow economy in Turkey are thought to be governance related.

With the present and future being shaped by the Coronavirus disease and worldwide responses to it, critical insights are essential. The Covid-19 pandemic has profoundly influenced the lives of most people on the plane as well as the global market, some experts believing it has caused the worst economic decline since the Great Depression. The pandemic found States unprepared to face the challenges brought by it, it has exposed the vulnerabilities of individuals, societies and economies. A few months after the sparking of the first wave of Covid-19 it was possible to assess the earliest public intervention and to foresee how the virus is going to impact economic and social systems. Given the significant increase in public expenditure since the beginning of the pandemic, this Article will articulate and explore the role of public procurement in anticipating the risk of market failure, despite the complicated environment. Likewise, focus will be drawn upon the EU soft law instruments designed to respond to economic and public health issues, through the prism of solidarity. The Article will then focus on the analysis of the Italian response to the pandemic through public purchasing techniques.

The role of the service sector in the economy is increasing in the process of socio-economic development. This tendency has been confirmed and explained by the three-sector theory formulated by A.G.B. Fisher, C. Clark, and J. Fourastie. The main goal of the paper is to show development tendencies in service sectors in Poland and the EU countries and assess them in view of the three-sector theory. The share of the service sector in the total employment and in the total gross value added in the years 2005-2013/2014 will be analysed together with two sub-sectors including market and non-market services. The research shows that the share of the service sector in total employment and total gross value added has been recently increasing in Poland as well as in other EU countries, but there is a gap in this process between Poland and the most developed EU countries. Moreover, in Poland, the role of market services has been recently increasing much faster than the role of non-market services.

The article is devoted to the study of the implementation of territorial cohesion policy in the European Union in order to achieve a secure regional coexistence. In particular, the regulatory and institutional origins of territorial cohesion policy in the EU are considered. The evolution of ontological models of cohesion policy has been outlined. Specifically, the emphasis is placed on the key objective of political geography – effectively combining the need for "territorialization" and the growing importance of networking. The role of urbanization processes in the context of cohesion policy is highlighted. Cross-border dimensions of cohesion policy in the context of interregional cooperation are explored. Particular emphasis is placed on the features of integrated sustainable development strategies.
