The stone bracelets are one of the most outstanding elements of personal ornaments of the ancient Neolithic in Western Mediterranean and the South of the Iberian Peninsula (5500-4800 cal. BCE). These bracelets are considered an element of cultural identity and a chronological marker of the first Neolithic societies in these areas. The study of the production processes of this ornament has brought a new approach to social relations of the early Neolithic groups of this area. The existence of specialized workshops and the circulation of these objects show the shift towards more complex social organizations. The aim of this paper is to present knapping methods and techniques carried out in the Neolithic bracelets quarry of the Cortijo Cevico. This quarry has recently been discovered and excavated, and it is the first site of its kind in the Iberian Peninsula. It is a rocky outcrop in the geological formation of Trías de Antequera, formed by dolomitic marbles. On this site we carried out the extraction works, as well as the first transformation of the knapping performs that were going to be processed as bracelets. In addition, we have applied for the first time in this paper the methodology consists on using diacritical schemes in the knapping waste of the bracelets. This methodology, along with experimentation and technical stigmas, has allowed the recognition of the techniques and methods applied to knapping dolomitic marbles and these are presented for the first time in this paper.

Ochthebius (Ochthebius) lobiccoastal habitatsollis Rey, 1885 is recorded for the first time from the Iberian Peninsula (Girona) and the island of Corsica; new records are also given for the islands of Menorca and Sardinia. The species is known only from coastal habitats through the Gulf of Lion and the Ligurian and Balearic seas, typically living in rockpools of different salinity or small trickles or freshwater runoffs. Genetic data of the cytochrome oxidase 1 gene from Iberian, Menorcan and Sardinian specimens shows less than 1% divergence, suggesting lack of isolation between populations.

The Subject

The nature of social organization during the Orcadian Neolithic has been the subject of discussion for several decades with much of the debate focused on answering an insightful question posed by Colin Renfrew in 1979. He asked, how was society organised to construct the larger, innovative monuments of the Orcadian Late Neolithic that were centralised in the western Mainland? There are many possible answers to the question but little evidence pointing to a probable solution, so the discussion has continued for many years. This paper takes a new approach by asking a different question: what can be learned about Orcadian Neolithic social organization from the quantitative and qualitative evidence accumulating from excavated domestic structures and settlements?In an attempt to answer this question, quantitative and qualitative data about domestic structures and about settlements was collected from published reports on 15 Orcadian Neolithic excavated sites. The published data is less extensive than hoped but is sufficient to support a provisional answer: a social hierarchy probably did not develop in the Early Neolithic but almost certainly did in the Late Neolithic, for which the data is more comprehensive.While this is only one approach of several possible ways to consider the question, it is by exploring different methods of analysis and comparing them that an understanding of the Orcadian Neolithic can move forward.

Purpose – Within team-oriented approaches, tasks are assigned to teams before being assigned to workstations as a reality of industry. So it becomes clear, which workers assemble which tasks. Design/methodology/approach – Team numbers of the assembly line can increase with the number of tasks, but at the same time, due to physical situations of the stations, there will be limitations of maximum working team numbers in a station. For this purpose, heuristic assembly line balancing (ALB) procedure is used and mathematical model is developed for the problem. Findings – Well-known assembly line test problems widely used in the literature are solved to indicate the effectiveness and applicability of the proposed approach in practice. Originality/value – This paper draws attention to ALB problem in which workers have been assigned to teams in advance due to the need for specialized skills or equipment on the line for the first time.

Batio3 Nanoparticles

For the first time, the BaTiO3 nano-sized particles were obtained through solid-state reaction by employing the titanium oxide nanoparticle. Meanwhile, by using TiO2 with micro-sized particles, the synthesized BaTiO3 shows the micro-sized. The XRD pattern confirms that both BaTiO3 nano-sized and micro-sized particles display the tetragonal structure. Both SEM and TEM analysis revealed that the size of the nano-sized material is in the range of 30–50 nm; in the meantime, the microsized material shows a size of 500 nm. The Eg of both BaTiO3 micro-sized and nano-sized were calculated by using the Kubelka-Munk function. The shifted bandgap of BaTiO3 nano-sized particle is nearly 0.24 eV larger than that of BaTiO3 miro-sized particle due to the particle size effect. The P-E measurement of n-BaTiO3 proved that the obtained BaTiO3 nano-sized is ferroelectric material. The result may provide a new route for the fabrication of barium titanate nanoparticle with ferroelectric properties.

This chapter gives a rapid overview of the history of Roman public and private institutions, from their early beginning in the semi-legendary age of the kings to the later developments of the Imperial age. A turning point has been the passage from the kingdom to the republic and the new foundation of citizenship on family wealth, instead of the exclusiveness of clan and lineages. But still more important has been the approval of the written legislation of the XII Tables giving to all citizens a sufficient knowledge of the Roman legal body of consuetudinary laws. From that moment, Roman citizenship was identified with personal freedom and the rule of law. Following political and military success, between the end of IV and the first half of III century bce Rome was capable of imposing herself as the central power in Italy and the western Mediterranean. From that moment Roman hegemony was exercised on a growing number of cities and local populations, organized in the form of Roman of Latin colonies or as Roman municipia. Only in the last century bce were these different statutes unified with the grant of Roman citizenship to all Italians. In this same period the Roman civil law, which was applied to private litigants by the Roman praetors, had become a very complex and sophisticated system of rules. With the empire the system did not change abruptly, although the Princeps did concentrate in his hands the last power of the judiciary and became the unique source of new legislation. In that way, for the first time, the Roman legal system was founded on rational and coherent schemes, becoming a model, which Antiquity transmitted to the late medieval Europe.

Two well-known archaeological sites, the peat bogs of Shigir and Gorbunovo (Middle Urals, Russia), have been radiocarbon dated (61 conventional and accelerator mass spectrometry [AMS] dates from various natural and artifact samples). For the first time, a detailed chronology of Early to Late Mesolithic and Early Neolithic occupation for this region has been obtained, and a paleoenvironmental history reconstructed. Based on these results, we propose that the Mesolithic settlement of the Middle Urals region started in the early Holocene, at the same time as in central and eastern Europe.

This paper offers a revised theoretical model to understand the historical development of labor under capitalism. Drawing on Antonio Gramsci, Karl Polanyi, and Nancy Fraser, the revised model highlights how state politics and ideologies have reshaped formal and informal labor to fuel evolving accumulation models since the 1950s. It also deepens our analysis of the potential and limits of labor's contemporary countermovements. Potential advances must be read in terms of increased protection and increased recognition relative to earlier eras. Limits must be read relative to the hegemonic forces splintering workers’ countermovements. Applying the revised model to the empirical case of Indian informal workers in various sectors, I illustrate how the Indian state used informal workers as a political actor (not just an economic actor) to organize consent for a powerful new hegemonic project of market reforms (of the Gramscian variety) that undid labor's twentieth-century gains and empowered large businesses, but retained democratic legitimacy with the mass labor force. I also expose and evaluate two kinds of countermovements emerging from below by Indian workers: self-protection movements (of the Polanyian variety) and emancipatory/recognition movements (of the Fraserian variety). India's recent hegemonic project enabled informal workers to counteract the dehumanizing effects of labor commodification by offering an alternative labor protection model. This model has the potential to redefine the working class (and its protection) to include multiple employment relationships for the first time. It also promises to recognize the social relations between multiple categories of vulnerable populations, reminding us that caste, gender, and class are mutually constitutive (rather than mutually exclusive). But this model is highly constrained by contemporary hegemonic forces, highlighting the complex relationship of society to state—one of contestation and, for the sake of survival, collaboration.
