Related party transactions, corporate governance and accounting quality in Greece

Related Party Transactions (RPTs) have been considered recently in research as a phenomenon which is associated with several financial scandals, shareholder’s wealth expropriation and is used for earnings management (EM) purposes by the reporting entity. This study aimed to: (i) assess the extent of EM and RPTs i Greece; (ii) investigate the association between RPTs and EM; (iii) investigate the association between corporate governance and EM; (iv) investigate the association between corporate governance and RPTs; and (v) investigate the impact of RPTs on Accounting Quality. Greece was selected for this study as it provides a special context due to poor investor protection, high levels of EM and unhealthy financial reporting environment where wealth extraction and EM are more likely. This study examines the relationship between earnings management and RPTs for the firms listed on the Athens Stock Exchange (ASE). Moreover, it examines the association between earnings management and corporate governance activities. The results show a negative and significant relationship between EM and RPTs. This finding does not support the conclusion that RPTs are necessarily conducted to mask fraud or the extraction of firm resources. The results show that firms audited by one of the Big 4 audit firms are associated with less EM. Additionally, the study investigates the relationship between RPTs and accounting quality. The findings show that that there is no significant difference in accounting quality between RPTs firms and non-RPTs firms. This study contributes to the EM, accounting quality and corporate governance literatures. This research suggests recommendations for researchers, data providers and policy makers on ways to reduce the problems associated with RPTs.

Optimal design of the renewable energy map of Greece using weighted goal-programming and data envelopment analysis

Renewable energy forms have been widely used in the past decades highlighting a "green" shift in energy production. An actual reason behind this turn to renewable energy production is EU directives which set the Union's targets for energy production from renewable sources, greenhouse gas emissions and increase in energy efficiency. All member countries are obligated to apply harmonized legislation and practices and restructure their energy production networks in order to meet EU targets. Towards the fulfillment of 20-20-20 EU targets, in Greece a specific strategy which promotes the construction of large scale Renewable Energy Source plants is promoted. In this paper, we present an optimal design of the Greek renewable energy production network applying a 0-1 Weighted Goal Programming model, considering social, environmental and economic criteria. In the absence of a panel of experts Data Envelopment Analysis (DEA) approach is used in order to filter the best out of the possible network structures, seeking for the maximum technical efficiency. Super-Efficiency DEA model is also used in order to reduce the solutions and find the best out of all the possible. The results showed that in order to achieve maximum efficiency, the social and environmental criteria must be weighted more than the economic ones.

Using the e-Class Open Platform for e-Learning Support at the TEI of Larissa, Greece

In the current paper we firstly give a short introduction on e-learning platforms and review the case of the e-class open e-learning platform being used by the Greek tertiary education sector. Our analysis includes strategic selection issues and outcomes in general and operational and adoption issues in the case of the Technological Educational Institute (TEI) of Larissa, Greece. The methodology is being based on qualitative analysis of interviews with key actors using the platform, and statistical analysis of quantitative data related to adoption and usage in the relevant populations. The author has been a key actor in all stages and describes his insights as an early adopter, diffuser and innovative user. We try to explain the issues under consideration using existing past research outcomes and we also arrive to some conclusions and points for further research.

Optimal combination of energy crops under different policy scenarios:the case of Northern Greece

Energy crops production is considered as environmentally benign and socially acceptable, offering ecological benefits over fossil fuels through their contribution to the reduction of greenhouse gases and acidifying emissions. Energy crops are subjected to persistent policy support by the EU, despite their limited or even marginally negative impact on the greenhouse effect. The present study endeavors to optimize the agricultural income generated by energy crops in a remote and disadvantageous region, with the assistance of linear programming. The optimization concerns the income created from soybean, sunflower (proxy for energy crop), and corn. Different policy scenarios imposed restrictions on the value of the subsidies as a proxy for EU policy tools, the value of inputs (costs of capital and labor) and different irrigation conditions. The results indicate that the area and the imports per energy crop remain unchanged, independently of the policy scenario enacted. Furthermore, corn cultivation contributes the most to iFncome maximization, whereas the implemented CAP policy plays an incremental role in uptaking an energy crop. A key implication is that alternative forms of motivation should be provided to the farmers beyond the financial ones in order the extensive use of energy crops to be achieved.

Immigration and nationalism in Greece

A source of emigration until the early 1970s, Greece has become home to a rising tide of immigrants since 1991, and its foreign-born population rose from below one to over 11 percent. Equally important is the fact that the Greek state has historically premised national belonging on ethnicity, and striven to exclude people who did not exhibit Greek ethnic traits. My study examines how immigration has challenged this nationalist model of ethnically homogeneous belonging. Further, it uses the Greek case to problematize the hegemonic assumption that the nationalist model of social organization is a human universal. Data consist of reactions to a 2010 landmark law that constituted the first jus soli bill in the nation's history, and include a plurality of voices found in parliamentary proceedings, newspapers, a government-sponsored online forum and Facebook discussions. Voices examined correspond to three main conceptual camps: people who premise belonging on ethnicity and hegemonic definitions of what it means to be Greek, people who mitigate nationalist norms enough to include immigrants, but reproduce a nationalist worldview, and people who seek to divorce political belonging from ethnicity altogether.

Dedication and Display of Portrait Statues in Hellenistic Greece: Spatial Practices and Identity Politics

This dissertation models a new approach to the study of ancient portrait statues—one that situates them in their historical, political, and spatial contexts. By bringing into conversation bodies of evidence that have traditionally been studied in discrete categories, I investigate how statue landscapes articulated and reinforced a complex set of political and social identities, how space was utilized and manipulated on a local and a regional level, and how patrons responded to the spatial pressures and visual politics of statue dedication within a constantly changing landscape.

Instead of treating sites independently, I have found it to be more productive—and, indeed, necessary—to examine broader patterns of statue dedication. I demonstrate that a regional perspective, that is, one that takes into account the role of choice and spatial preference in setting up a statue within a regional network of available display locations, can illuminate how space shaped the ancient practice of portrait dedication. This level of analysis is a new approach to the study of portrait statues and it has proved to be a productive way of thinking about how statues and context were used together to articulate identity. Understanding how individual monuments worked within these broader landscapes of portrait dedications, how statue monuments functioned within federal systems, and how monuments set up by individuals and social groups operated along side those set up by political bodies clarifies the important place of honorific statues as an expression of power and identity within the history of the site, the region, and Hellenistic Greece.

Globalizing the Sculptural Landscapes of the Sarapis and Isis Cults in Hellenistic and Roman Greece

“Globalizing the Sculptural Landscape of Isis and Sarapis Cults in Roman Greece,” asks questions of cross-cultural exchange and viewership of sculptural assemblages set up in sanctuaries to the Egyptian gods. Focusing on cognitive dissonance, cultural imagining, and manipulations of time and space, I theorize ancient globalization as a set of loosely related processes that shifted a community's connections with place. My case studies range from the 3rd century BCE to the 2nd century CE, including sanctuaries at Rhodes, Thessaloniki, Dion, Marathon, Gortyna, and Delos. At these sites, devotees combined mainstream Greco-Roman sculptures, Egyptian imports, and locally produced imitations of Egyptian artifacts. In the last case, local sculptors represented Egyptian subjects with Greco-Roman naturalistic styles, creating an exoticized visual ideal that had both local and global resonance. My dissertation argues that the sculptural assemblages set up in Egyptian sanctuaries allowed each community to construct complex narratives about the nature of the Egyptian gods. Further, these images participated in a form of globalization that motivated local communities to adopt foreign gods and reinterpret them to suit local needs.

I begin my dissertation by examining how Isis and Sarapis were represented in Greece. My first chapter focuses on single statues of Egyptian gods, describing their iconographies and stylistic tendencies through examples from Corinth and Gortyna. By comparing Greek examples with images of Sarapis, Isis, and Harpokrates from around the Mediterranean, I demonstrate that Greek communities relied on globally available visual tropes rather than creating site or region-specific interpretations. In the next section, I examine what other sources viewers drew upon to inform their experiences of Egyptian sculpture. In Chapter 3, I survey the textual evidence for Isiac cult practice in Greece as a way to reconstruct devotees’ expectations of sculptures in sanctuary contexts. At the core of this analysis are Apuleius’ Metamorphoses and Plutarch’s De Iside et Osiride, which offer a Greek perspective on the cult’s theology. These literary works rely on a tradition of aretalogical inscriptions—long hymns produced from roughly the late 4th century B.C.E. into the 4th century C.E. that describe the expansive syncretistic powers of Isis, Sarapis, and Harpokrates. This chapter argues that the textual evidence suggests that devotees may have expected their images to be especially miraculous and likely to intervene on their behalf, particularly when involved in ritual activity inside the sanctuary.

In the final two chapters, I consider sculptural programs and ritual activity in concert with sanctuary architecture. My fourth chapter focuses on sanctuaries where large amounts of sculpture were found in underground water crypts: Thessaloniki and Rhodes. These groups of statues can be connected to a particular sanctuary space, but their precise display contexts are not known. By reading these images together, I argue that local communities used these globally available images to construct new interpretations of these gods, ones that explored the complex intersections of Egyptian, Greek, and Roman identities in a globalized Mediterranean. My final chapter explores the Egyptian sanctuary at Marathon, a site where exceptional preservation allows us to study how viewers would have experienced images in architectural space. Using the Isiac visuality established in Chapter 3, I reconstruct the viewer's experience, arguing that the patron, Herodes Atticus, intended his viewer to inform his experience with the complex theology of Middle Platonism and prevailing elite attitudes about Roman imperialism.

Throughout my dissertation, I diverge from traditional approaches to culture change that center on the concepts of Romanization and identity. In order to access local experiences of globalization, I examine viewership on a micro-scale. I argue that viewers brought their concerns about culture change into dialogue with elements of cult, social status, art, and text to create new interpretations of Roman sculpture sensitive to the challenges of a highly connected Mediterranean world. In turn, these transcultural perspectives motivated Isiac devotees to create assemblages that combined elements from multiple cultures. These expansive attitudes also inspired Isiac devotees to commission exoticized images that brought together disparate cultures and styles in an eclectic manner that mirrored the haphazard way that travel brought change to the Mediterranean world. My dissertation thus offers a more theoretically rigorous way of modeling culture change in antiquity that recognizes local communities’ agency in producing their cultural landscapes, reconciling some of the problems of scale that have plagued earlier approaches to provincial Roman art.

These case studies demonstrate that cultural anxieties played a key role in how viewers experienced artistic imagery in the Hellenistic and Roman Mediterranean. This dissertation thus offers a new component in our understanding of ancient visuality, and, in turn, a better way to analyze how local communities dealt with the rise of connectivity and globalization.

Sedimentology of a profile from Etoliko Lagoon, Western Greece

A key feature of Greece is the large amount of historical and archaeological records. The sedimentary record of the Etoliko Lagoon, Aetolia, Western Greece, offers an ideal opportunity to study human-environment interaction and to disentangle natural and anthropogenic imprints in the sedimentary record. By applying an interdisciplinary approach of combining geoscientific methods (XRF, LOI, grain size analysis) with archaeological and historical records, the 8.8 m long sedimentary sequence ETO1C reveals the palaeoenvironmental history of the lagoon and its catchment since 11,670 cal BP. With a thorough chronology based on 14C age-depth-modelling including varve counting, different evolutionary stages were put in a chronological context. These stages include a lake period (11,670-8310 cal BP) followed by a period of sporadic saltwater intrusion (8310-1350 cal BP) as a result of continuing transgression. Phases of limnic predominance associated with freshwater inflow of episodically activated distributaries (around 5230 cal BP) still occurred. By 1350 cal BP, ongoing sea level rise had connected the lagoons of Etoliko and Messolonghi and freshwater influence had ceased. With the onset of settlement activity in the Late Helladic (1700-1100 cal BC) humans took advantage of the prevailing environmental landscape. A sudden increase in coarse sedimentation correlates with the history of human occupation with its peak of prosperity from the Late Helladic until the end of the Hellenistic Period (30 cal BC).

The relationship between vegetation and modern pollen assemblages on Mount Paggeo (NE Greece)

In this study, we investigated the relationship between vegetation and modern-pollen rain along the elevational gradient of Mount Paggeo. We apply multivariate data analysis to assess the relationship between vegetation and modern-pollen rain and quantify the representativeness of forest zones. This study represents the first statistical analysis of pollen-vegetation relationship along an elevational gradient in Greece. Hence, this paper improves confidence in interpretation of palynological records from north-eastern Greece and may refine past climate reconstructions for a more accurate comparison of data and modelling. Numerical classification and ordination were performed on pollen data to assess differences among plant communities that beech (Fagus sylvatica) dominates or co-dominates. The results show a strong relationship between altitude, arboreal cover, human impact and variations in pollen and nonpollen palynomorph taxa percentages.

Neoliberal Capitalism, Social Reproduction Crisis, Gender Implications and Forms of Resistance: The case of Greece

Neoliberal capitalism and its accompanied austerity measures has had a profound effect on social reproduction throughout Europe. Social reproduction, ie, the process that makes it possible for individuals, families, and society to reproduce itself – is in crisis. The concept of social reproduction utilized in this presentation is framed within the feminist and Marxist tradition. Historically, social reproduction was met through both waged and unwaged work with women playing a predominant role either as waged, predominantly public sector, workers (social workers, teachers, carers, nurses, etc) or as unpaid workers (unpaid carers: mothers, wives, etc.) but now both forms of work are destabilized and undermined. Thus, the crisis in social reproduction. Within this crisis women’s unequal position is further undermined but at the same time progressive women and men are organizing to present alternatives forms of social reproduction. This presentation by utilizing the case of Greece will first outline the neoliberal processes that have caused the crisis in social reproduction. Second, it will present the consequences of social reproduction by highlighting the gender implications. Third, it will discuss the reorganization of social reproduction which is taking place outside the logic of capitalist society and is manifested through the creation of solidarity health clinics and pharmacies, communal kitchens, creation of various forms of bartering etc. This presentation will argue that these forms present glimpses of another society , a society based on principles of solidarity and cooperation. A society worth fighting for. And finally the presentation will conclude by discussing at which level can this crisis be resolved and the role of the social work profession.

Kalaureia 1894 : A Cultural History of the First Swedish Excavation in Greece

The excavation of the Sanctuary of Poseidon at Kalaureia in 1894 marks the beginning of Swedish archaeological fieldwork in Greece. During a couple of hot summer months, two philologists from Uppsala University, Sam Wide (1861-1918) and Lennart Kjellberg (1857-1936), worked in the sanctuary together with the architect Sven Kristenson (1858-1937), the Greek foreman Pankalos and around twenty local workmen. In 1997, the Swedish Institute at Athens began new excavations at the sanctuary. This thesis examines the beginnings of Swedish fieldwork in Greece. Within the framework of a cultural history of archaeology, inspired by archaeological ethnography and the New Cultural History, it explores how archaeology functioned as a cultural practice in the late nineteenth century. A micro-historical methodology makes use of a wide array of different source material connected to the excavation of 1894, its prelude and aftermath. The thesis takes the theoretical position that the premises for archaeological knowledge production are outcomes of contemporary power structures and cultural politics. Through an analysis of how the archaeologists constructed their self-images through a set of idealized stereotypes of bourgeois masculinity, academic politics of belonging is highlighted. The politics of belonging existed also on a national level, where the Swedish archaeologists entered into a competition with other foreign actors to claim heritage sites in Greece. The idealization of classical Greece as a birthplace of Western values, in combination with contemporary colonial and racist cultural frameworks in Europe, created particular gazes through which the modern country was appropriated and judged. These factors all shaped the practices through which archaeological knowledge was created at Kalaureia. Some excavations tend to have extensive afterlives through the production of histories of archaeology. Therefore, this thesis also explores the representations of the 1894 excavation in the historiography of Swedish classical archaeology. It highlights the strategies by which the excavation at Kalaureia has served to legitimize further Swedish engagements in Greek archaeology, and explores the way in which historiography shapes our professional identities.
