The early evolution of archosauromorphs during the Permo-Triassic constitutes an excellent empirical case study to shed light on evolutionary radiations in deep time and the timing and processes of recovery of terrestrial faunas after a mass extinction. However, macroevolutionary studies of early archosauromorphs are currently limited by poor knowledge of their phylogenetic relationships. In particular, one of the main early archosauromorph groups that need an exhaustive phylogenetic study is “Proterosuchia,” which as historically conceived includes members of both Proterosuchidae and Erythrosuchidae. A new data matrix composed of 96 separate taxa (several of them not included in a quantitative phylogenetic analysis before) and 600 osteological characters was assembled and analysed to generate a comprehensive higher-level phylogenetic hypothesis of basal archosauromorphs and shed light on the species-level interrelationships of taxa historically identified as proterosuchian archosauriforms. The results of the analysis using maximum parsimony include a polyphyletic “Prolacertiformes” and “Protorosauria,” in which the PermianAenigmastropheusandProtorosaurusare the most basal archosauromorphs. The enigmatic choristoderans are either found as the sister-taxa of all other lepidosauromorphs or archosauromorphs, but consistently placed within Sauria. Prolacertids, rhynchosaurs, allokotosaurians and tanystropheids are the major successive sister clades of Archosauriformes. The Early TriassicTasmaniosaurusis recovered as the sister-taxon of Archosauriformes. Proterosuchidae is unambiguosly restricted to five species that occur immediately after and before the Permo-Triassic boundary, thus implying that they are a short-lived “disaster” clade. Erythrosuchidae is composed of eight nominal species that occur during the Early and Middle Triassic. “Proterosuchia” is polyphyletic, in which erythrosuchids are more closely related toEuparkeriaand more crownward archosauriforms than to proterosuchids, and several species are found widespread along the archosauromorph tree, some being nested within Archosauria (e.g., “Chasmatosaurus ultimus,”Youngosuchus). Doswelliids and proterochampsids are recovered as more closely related to each other than to other archosauromorphs, forming a large clade (Proterochampsia) of semi-aquatic to aquatic forms that includes the bizarre genusVancleavea.Euparkeriais one of the sister-taxa of the clade composed of proterochampsians and archosaurs. The putative Indian archosaurYarasuchusis recovered in a polytomy withEuparkeriaand more crownward archosauriforms, and as more closely related to the RussianDongusuchusthan to other species. Phytosaurs are recovered as the sister-taxa of all other pseudosuchians, thus being nested within Archosauria.

Despite the popularity of distributed leadership theory, the investigation of the micro-political aspects of such models have scarcely been explored, and insights on the cultural variety of distributed practices in schools are limited. The present study aimed to explore what micro-political aspects emerge in participative decision making in collectivist and individualist cultures. To this end, a multiple case study method was adopted, focusing on four Israeli public high schools. Schools were chosen to represent an ‘extreme’ case selection rationale: two non-religious urban schools representing individualist cases, and two communal schools in religious kibbutzim representing communal schools. The analysis shed light on three micro-political points of comparison between the prototypes of participative decision making in collectivist and individualist cultures related to control, actors, and stage crafting. The findings and implications are discussed.

The aim of this paper is to shed light on the question regarding whether the integration of an electric battery as a part of a domestic installation may increase its energy efficiency in comparison with a conventional case. When a battery is included in such an installation, two types of electrical conversion must be considered, i.e., AC/DC and DC/AC, and hence the corresponding losses due to these converters must not be forgotten when performing the analysis. The efficiency of the whole system can be increased if one of the mentioned converters is avoided or simply when its dimensioning is reduced. Possible ways to achieve this goal can be: to use electric vehicles as DC suppliers, the use of as many DC home devices as possible, and LED lighting or charging devices based on renewables. With all this in mind, several scenarios are proposed here in order to have a look at all possibilities concerning AC and DC powering. With the aim of checking these scenarios using real data, a case study is analyzed by operating with electricity consumption mean values.

AbstractNumerous studies have dealt with the process of globalization and its various cultural products. Three such cultural products illustrate this process: Vikas Swarup’s novel Q and A (2005), the TV quiz show Kaun banega crorepati? (Who Wants to Be a Millionaire?), and Danny Boyle’s film Slumdog Millionaire (2008). The novel, the TV show and the film have so far been studied separately. Juxtaposing and comparing Q and A, Kaun banega crorepati, and Slumdog Millionaire provides an effective means to shed light on the dialogic and interactive nature of the process of globalization. It is argued through this case study that an analysis of their place of production, language and content, helps clarify the derivative concepts of “glocalization” and “grobalization” with regard to the way(s) contemporary cultural products respond to globalization.

Entrepreneurial education offers valuable opportunities for teachers to foster and enhance creativity and action competence, which are also important for sustainability education. The University of Wales Trinity Saint David (UWTSD) is a leader in the development of entrepreneurial education in teacher education both in Wales and internationally. The objective of this article is to shed light on how an entrepreneurial education approach can help foster social change. The aim of this study is to learn from teacher educators at UWTSD about how they support creativity, innovation, and an enterprising mindset in their learners. A case study approach is applied. By analysing documentary evidence such as module and assignment handbooks, we explore how teacher educators at UWTSD deliver entrepreneurial education for social change. Our findings indicate that UWTSD’s development of entrepreneurial education in teacher training has enabled constructive learning, cultivating creativity and action competence. We provide examples that display how the intentions of the Curriculum for Wales and entrepreneurial education approaches of the UWTSD emerge in practice. These examples show outcomes of the entrepreneurial projects that evince the enactment of social change. The findings also show that the educational policy of Wales supports entrepreneurial education throughout all levels of the educational system.

Based on a new online database of Celtic personal names, this research demonstrates how the study of Romano-British onomastics can shed light on the complexities of linguistic and cultural contacts, complementing archaeological material and literary sources. After an introductory section on methodology, Part One analyses naming formulae and expressions of filiation as evidence for both continuity and change dependent on social and geographical factors. Confusion and contamination between the Latin and Celtic systems proved much less common than on the Continent, where earlier contact with Roman culture and the written tradition for Continental Celtic occasionally facilitated an unusual form of syncretism. Part Two examines the naming formulae attested at Roman Bath and the mechanisms by which Celts adopted Latin names. The case-study of Bath relates continuity and change in both naming formulae and nomenclature to an acceptance of, or resistance to, ‘Romanization’ in Britain.

Productive Employment

Inclusiveness, with its emphasis on productive employment, has become central in development policy. From this perspective, unwaged-work is condemned for not being sufficiently productive; that is, for failing to lift incomes above a poverty threshold. However, insights from the sociology of work reveal a range of unwaged activities that are potentially highly productive in their contribution to self-reliance. The article explores whether these activities are undermined by the promotion of inclusiveness. The case study takes place in Tigray, Ethiopia. Through semi-structured interviews, the activities of different households were classified according to a typology of work based on the work of Gorz, Illich, Wheelock, Taylor, Williams and others. Results show the heterogeneous character of work and shed light on the meaning of productivity. The article ends with a discussion on the risk that inclusiveness may be achieved by replacing activities ‘that count’ with activities ‘that can be counted’.

The aim of this article is to furnish insights of the Italian public debate on the recognition of LGBTQ rights, which can be understood as an interesting case study of the complex relationship between (multi)secularisation processes and re/definition of citizenship models. More specifically, the article analyses two political events related to this debate that took place in Rome in June 2015. The first is the Family Day demonstration, promoted by conservative Catholic groups; the second is the LGBTQ Pride parade, promoted by various gay, lesbian and transsexual/gender associations. We analyse the official statements issued by the two organising committees of the demonstrations, adopting the framework and methods of the Critical Discourse Analysis. Above and beyond an evident political conflict between the two discourses, we try to shed light on their mutual construction on the basis of what we call ‘naturalization’ and ‘universalization’ processes.

Water scarcity is already causing serious challenges nowadays and devastating water-related processes will certainly continue for decades to come. The emerging water crisis requires new political arrangements, new technological solutions and the development of new water supply chains. Among the possible political-diplomatic answers, water trade may be a viable option, as water abundant countries could distribute resources by commercializing their water surplus. Water trade, however, faces serious obstacles. Dependence of different countries on states that have water surplus, political leverage and the possible opportunity when external powers could control the essentially important human needs are all examples of potential risks. These threats hinder the development of interstate water trade cooperation and orient countries struggling with water shortages towards domestic solutions. This study attempts to examine the practice of water scarcity and water diplomacy, while also applies the Turkish experience as a case study for demonstrating constraints of water trade. The paper will hopefully shed light on the threats posed by global and regional water scarcity and draw attention to the opportunities and limitations of water commercialization. The aim of our study is to outline the issues related to the distribution and trade of water, furthermore to present the problems of water as a product. Our research focuses primarily on Turkey, which has also become involved in water trade, but the story still ended in failure.

The present paper aims to highlight the physical evolution of solutions from soaking and beans cooking process. This is motivated by the desire to shed light on the particular behavior of the bean end-of-cooking solutions when they are incorporated into the soil. For that purpose, solutions from soaking were produced by putting in contact 2kg of sorted and quickly washed beans seed with 8kg of water with known physical characteristics. Concerning the solutions from cooked beans, they were produced by putting on fire the pot containing the mixture of the water from soaking and bean seeds. The beans were a variety of Phaseolus vulgaris L.,known as “Meringue”. The cooking process was done without salts. The samples of solutions were collected as follow: 30 and 60 minutes respectively after the beginning of the soaking, 30, 60, and 90 minutes after the beginning of the cooking process of the beans soaked during 60 minutes. After each sampling, the equal volume of the solution collected was replaced with the water used for the cooking process. The color of the water used for the cooking process is translucent. Concerning solutions from soaking, their coloration are gradually reddish. Solutions from soaking and cooking process became abruptly dark red. From 60 minutes of the cooking process after soaking, the dark red coloration turn to strong brown. The solution handled in the case of the present study, from soaking and cooking the beans are gradually enriched in flakes compared to the situation noticed in the water used for the cooking process. But, the enrichment becomes abruptly high with the beginning of the cooking process after the process of soaking. In terms of consequence, their physical parameters studied in the present case study all increase in the same manner, notably the mass, the volumetric mass, and the density of the different solutions. The infiltration tests made including the water used for the different processes, solutions form the end of cooking the beans, and human urine show that the infiltration rate of the water from cooked beans is very low compared to that of the water used for the processes and human urine. The total infiltration of solution of the end of cooking the bean reveals on the infiltration surface the presence of a film of a matter bearing molds, generated by the progressive settling of this solution. The correlations established between the different parameters followed up here are highly positive. But in detail, the influence of an under laid parameter, known here as temperature, has been identified as being the responsible of the questioned behavior of the parameters taken in pairs in the case of correlation studies made. Finally, from this work, it emerges that the specific behavior of the bean end-of-cooking solution when it is introduced into the soil is justified by its progressive enrichment in organic matter during the cooking process.
