For some years past there has been a welcome change of emphasis towards the consideration of staging in books published on Greek tragedy; and yet with that change also a curious failure to be explicit about the central problem connected with all stagecraft, namely that of the acting-area. In this study two scholars with considerable experience of teaching classical drama in performance consider this problem of the acting-area in close relation to major scenes from two Greek tragedies, and suggest some general conclusions. The article must stand to some extent as a critique of the succession of books that has followed the apparently pioneering study of Oliver Taplin, none of which has made any substantial or sustained attempt to indicate where actors might have acted in the performance of Greek tragedy, though most, if not all, have been prepared to discard the concept of a raised ‘stage’ behind the orchestra. Hippolytus (428 BC) is the earliest of the surviving plays of Euripides to involve three speaking actors in one scene. Both Alcestis (438 BC and Medea (431 BC almost certainly require three actors to be performed with any fluency, but surprisingly present their action largely through dialogue and confrontation — surprisingly, perhaps, because at least since 458 BC and the performance of the Oresteia it is clear that three actors were available to any playwright.

This article analyses the relationship between migrant entrepreneurship, marginalisation and social innovation. It does so, by looking how their ‘otherness’ is used on the one hand to reproduce their marginalised situation in society and on the other to develop new living and working arrangements promoting social innovation in society. The paper is based on a qualitative study, which was carried out from March 2014- 2016. In this period, twenty semi-structured interviews were conducted with migrant entrepreneurs and experts. As the results show, migrant entrepreneurs are characterised by a false dichotomy of “native weakness” in economic self-organisation against the “classical strength” of majority entrepreneurs. It is shown that new possibilities of acting in the context of migrant entrepreneurship are mostly organised in close relation to the lifeworlds and specific needs deriving from this sphere. Social innovation processes initiated by migrant entrepreneurs through their economic activities thus develop on a micro level and are hence less apparent. Supportive networks are missing on a structural level, so it becomes difficult for single innovative initiatives to be long-lasting.

Gambuh as the performing art in Malay area became one of the cultural transformation evidences of the close relation between Java and Malay. The history of gambuh performance in Malay area recorded in the archipelago’s manuscripts, one of them is a manuscript entitled Surat Gambuh which is being the collection of Leiden University Library. This paper attempts to examine the contents of the manuscript in order to reconstruct the gambuh performance art in Malay and also trace the historical aspects. As far as the research had been done, there have been no studies of this manuscript so it is necessary to first transliterate it using a critical method. Furthermore, the historical aspects are explored using a historical approach by adding data from other texts of Panji. The analysis result of the reflection of Malay gambuh performance rules and historical aspects show that there is a transformation of work from oral tradition to written tradition, the cultural acculturation between Java and Malay, and the Islamic influence behind Malay gambuh.

The problem of providing the most efficient and rational selection, distribution, use of migrant workers, with regard to both internal and external migration in close relation to socio-economic and demographic interests of the state are currently of particular relevance. Scientific novelty of work consists in the identification of factors and directions of flows as departing and arriving labor migrants in the Republic of Bashkortostan, the characteristics of the development of labour migration and its impact on employment, which allowed to identify problems and negative trends.

AbstractReuven Yaron (1924–2014) in memoriamThe importance of Ancient Jewish Law for Roman Law and Ancient Legal History – the example of the Rabbinic reception and modification of the Greco-Hellenistic diathēkē as dîjathîqî and the donatio mortis causa. This paper aims to show that ancient Jewish law is of greatest importance for interpreting Roman law and understanding ancient legal history. After exemplifying the close relation of the Pentateuch and the cuneiform law, we focus on the reception and modification of the Greco-Hellenistic diathēkē (testament), which came into Jewish law during tannaitic times as dîjathîqî and was reinterpreted by the rabbis as donation. Finally, we compare the rabbinic dîjathîqî and the Roman donatio mortis causa.

Abstract Background Our goal was to find out the relation between mammographic densities and cancer of the breast according to the recent ACR classification. From the medical records of Kasereliny Hospital, 49,409 women were subjected to digital mammography for screening, of which 1500 breast cancer cases were collected. The mammographic categories of breast density were ACR-A, B, C, and D, which were detected by two senior radiologists. All radiological classifications were made using both standard mammographic views bilaterally. Two-sided tests of statistical significance were represented by all the P values. Results From 2014 to 2019, 49,409 women came for digital mammographic screening, their age ranges between 40 and 65, and all of them are included in the study. One thousand cases of breast cancer cases were radiologically and pathologically diagnosed. Different densities were arranged in descending pattern depending on the frequency of positive cases: D (13.7%), C (3.3%), B (2.7%), A (2.2%). There is positive significant risk ratio among every higher mammographic density in comparison to the lower density. Conclusion Our study results show that the risk of breast cancer is in close relation to the mammographic breast density.

This review analyzes the main anatomical structures and neural pathways that allow the generation of autonomous and behavioral mechanisms that regulate body heat in mammals. The study of the hypothalamic neuromodulation of thermoregulation offers broad areas of opportunity with practical applications that are currently being strengthened by the availability of efficacious tools like infrared thermography (IRT). These areas could include the following: understanding the effect of climate change on behavior and productivity; analyzing the effects of exercise on animals involved in sporting activities; identifying the microvascular changes that occur in response to fear, pleasure, pain, and other situations that induce stress in animals; and examining thermoregulating behaviors. This research could contribute substantially to understanding the drastic modification of environments that have severe consequences for animals, such as loss of appetite, low productivity, neonatal hypothermia, and thermal shock, among others. Current knowledge of these physiological processes and complex anatomical structures, like the nervous systems and their close relation to mechanisms of thermoregulation, is still limited. The results of studies in fields like evolutionary neuroscience of thermoregulation show that we cannot yet objectively explain even processes that on the surface seem simple, including behavioral changes and the pathways and connections that trigger mechanisms like vasodilatation and panting. In addition, there is a need to clarify the connection between emotions and thermoregulation that increases the chances of survival of some organisms. An increasingly precise understanding of thermoregulation will allow us to design and apply practical methods in fields like animal science and clinical medicine without compromising levels of animal welfare. The results obtained should not only increase the chances of survival but also improve quality of life and animal production.

AbstractGiven a finite order ideal $${\mathcal {O}}$$ O in the polynomial ring $$K[x_1,\ldots , x_n]$$ K [ x 1 , … , x n ] over a field K, let $$\partial {\mathcal {O}}$$ ∂ O be the border of $${\mathcal {O}}$$ O and $${\mathcal {P}}_{\mathcal {O}}$$ P O the Pommaret basis of the ideal generated by the terms outside $${\mathcal {O}}$$ O . In the framework of reduction structures introduced by Ceria, Mora, Roggero in 2019, we investigate relations among $$\partial {\mathcal {O}}$$ ∂ O -marked sets (resp. bases) and $${\mathcal {P}}_{\mathcal {O}}$$ P O -marked sets (resp. bases). We prove that a $$\partial {\mathcal {O}}$$ ∂ O -marked set B is a marked basis if and only if the $${\mathcal {P}}_{\mathcal {O}}$$ P O -marked set P contained in B is a marked basis and generates the same ideal as B. Using a functorial description of these marked bases, as a byproduct we obtain that the affine schemes respectively parameterizing $$\partial {\mathcal {O}}$$ ∂ O -marked bases and $${\mathcal {P}}_{\mathcal {O}}$$ P O -marked bases are isomorphic. We are able to describe this isomorphism as a projection that can be explicitly constructed without the use of Gröbner elimination techniques. In particular, we obtain a straightforward embedding of border schemes in affine spaces of lower dimension. Furthermore, we observe that Pommaret marked schemes give an open covering of Hilbert schemes parameterizing 0-dimensional schemes without any group actions. Several examples are given throughout the paper.

The microstructural mechanisms providing delamination toughness in high-strength low-alloyed steels are briefly reviewed. Thermo-mechanical processing methods improving both the strength and impact toughness are described, with a close relation to the microstructures and textures developed. The effect of processing conditions on the microstructure evolution in steels with different carbon content is discussed. Particular attention is paid to tempforming treatment, which has been recently introduced as a promising processing method for high-strength low-alloyed steel semi-products with beneficial combination of strength and impact toughness. Tempforming consists of large strain warm rolling following tempering. In contrast to ausforming, the steels subjected to tempforming may exhibit an unusual increase in the impact toughness with a decrease in test temperature below room temperature. This phenomenon is attributed to the notch blunting owing to easy splitting (delamination) crosswise to the principle crack propagation. The relationships between the crack propagation mode, the delamination fracture, and the load-displacement curve are presented and discussed. Further perspectives of tempforming applications and promising research directions are outlined.

Affinely Adjustable Robust Counterpart

In this article, we discuss an alternative method for deriving conservative approximation models for two-stage robust optimization problems. The method mainly relies on a linearization scheme employed in bilinear programming; therefore, we will say that it gives rise to the linearized robust counterpart models. We identify a close relation between this linearized robust counterpart model and the popular affinely adjustable robust counterpart model. We also describe methods of modifying both types of models to make these approximations less conservative. These methods are heavily inspired by the use of valid linear and conic inequalities in the linearization process for bilinear models. We finally demonstrate how to employ this new scheme in location-transportation and multi-item newsvendor problems to improve the numerical efficiency and performance guarantees of robust optimization.
