Fire risk is perhaps the most common risk in the category of special emergencies, being a phenomenon that affects important areas of economic and social life, such as buildings, industrial facilities, public spaces, forests, crops, or transportation. Scientific investigation of fires is constituted as a set of organized actions, of technical nature, undertaken to determine the causes that led to the occurrence of fires, the source of ignition, and the circumstances that favored the event. Numerical fire modeling is a widely recognized and accepted tool for analysis in fire research. The results of the investigation carried out on-site are compared with the results of fire evolution obtained by computer simulation, using numerical models based on known input data, to verify different hypotheses regarding the cause of the fire. The advantages over experimental methods are expressed by low costs and substantial time savings. Moreover, several simulations can be run simultaneously, for different scenarios of the event or the analysis of different consequences. The paper presents the main advantages that numerical modeling by FDS methods brings in the technical-scientific expertise of fire, with implications in the data analysis, development, and testing of hypotheses, respectively in the selection process of the final hypothesis. words.

Complex Activities

Investigating the fire type events is characterized by a high degree of complexity, due to the fact that it has to find answers to aspects coming from multidisciplinary fields: technical-scientific, legal, organizational, psychological, etc. The management of the findings, the analyzed samples, and the resulting data implies a series of complex activities, based on the use of advanced procedures and techniques. Fire investigation aims to determine the source of ignition and all the components that contribute to define the cause of the fire, to assess the motivations of the involved persons and to decipher the mechanism of heat transfer or burning processes that describes the propagation and development of a fire. Often, in order to understand the mechanism of the pyrogenic phenomenon, the following approaches are used in the current practice: technical-scientific expertises, reconstruction of the event on the field or in the laboratory, sample analysis, and, last but not least, computer simulations. This paper aims to highlight the role of the numerical models used in the field of fire safety, respectively in the elaboration of the post-event, technical-scientific expertises, by presenting some results obtained from the computer simulations, used to substantiate the fire mechanism and to formulate the conclusions.

Calculation Procedures

Abstract Engineering based calculation procedures in fire safety science often consist of unknown or uncertain input data which are to be estimated by the engineer using appropriate and plausible assumptions. Thereby, errors in this data are induced in the calculation and thus, impact the number as well as the reliability of the results. In this paper a procedure is presented to directly quantify and consider unknown input properties in the process of calculation using distribution functions and Monte-Carlo Simulations. A sensitivity analysis reveals the properties which have a major impact on the calculation reliability. Furthermore, the results are compared to the numerical models of CFAST and FDS.

Psychological Dimensions

Summary: Deterioration in performance associated with decreased ability to sustain attention may be found in long and tedious task sessions. The necessity for assessing a number of psychological dimensions in a single session often demands “short” tests capable of assessing individual differences in abilities such as vigilance and maintenance of high performance levels. In the present paper two tasks were selected as candidates for playing this role, the Abbreviated Vigilance Task (AVT) by Temple, Warm, Dember, LaGrange and Matthews (1996) and the Continuous Attention Test (CAT) by Tiplady (1992) . However, when applied to a sample of 829 candidates in a job-selection process for air-traffic controllers, neither of them showed discriminative capacity. In a second study, an extended version of the CAT was applied to a similar sample of 667 subjects, but also proved incapable of properly detecting individual differences. In short, at least in a selection context such as that studied here, neither of the tasks appeared appropriate for playing the role of a “short” test for discriminating individual differences in performance deterioration in sustained attention.

Islamic Boarding school is an islamic education institution which has an identical tradition in indonesian muslim societuy. This institution has emerged long before the colonialism era in Indonesia. In its long history since years to pursue the concept of modernism, islamic boarding school, sometimes ,has also been perceived negatively because of transnasionalism ideology which is adopted in recent years. In that case, this paper aimed to describe the existence of islamic boarding school in indonesian social life. By argumenting and comparing some previous studies in this case to gain an accurate result. Moreover, this paper is intended to answer some western perception about islamic boarding school in Indonesia, and finally emphasize the role of islamic boarding school as a government partner and its function in creating democracy.  Keyword: Islamic Boarding School, Tradition, Modernization.

Subject. The article discusses how management transforms as artificial intelligence gets more important in governance, production and social life. Objectives. We identify and substantiate trends in management transformation as artificial intelligence evolves and gets more important in governance, production and social life. The article also provides our suggestions for management and training of managers dealing with artificial intelligence. Methods. The study employs methods of logic research, analysis and synthesis through the systems and creative approach, methodology of technological waves. Results. We analyzed the scope of management as is and found that threats and global challenges escalate due to the advent of artificial intelligence. We provide the rationale for recognizing the strategic culture as the self-organizing system of business process integration. We suggest and substantiate the concept of soft power with reference to strategic culture, which should be raised, inter alia, through the scientific school of conflict studies. We give our recommendations on how management and training of managers should be improved in dealing with artificial intelligence as it evolves. The novelty hereof is that we trace trends in management transformation as the role of artificial intelligence evolves and growth in governance, production and social life. Conclusions and Relevance. Generic solutions are not very effective for the Russian management practice during the transition to the sixth and seventh waves of innovation. Any programming product represents artificial intelligence, which simulates a personality very well, though unable to substitute a manager in motivating, governing and interacting with people.

To commemorate the 21st century, a new learning model was designed in 2013 curriculum, in which there is a shift from teachers give knowledge to students become student must actively seek out knowledge from a variety of learning resources. In this case, the teacher acts as facilitators. Thus, language is a very central role, because the language should be in front of all other subjects. Curriculum 2013 imposed a thematic integrated learning which is no longer based subjects. Various subjects for primary schools (such as: Religion, Civics, Indonesian, Mathematics, Science, Social Studies, and so on) are integrated intoone book. The subject matter is not presented in textbook, but it presented in book thematics lesson, the themes are about nature, social life and culture. In this new curriculum, learning process is implemented by applying a scientific approach (observing, questioning, experimenting, associating, and networking) that includes three aspects such as attitudes, knowledge, and skills. So, how is the role of Indonesian in an integrated thematic learning by applying scientific approaches in primary schools in 2013 curriculum? By appying the method, the object of this paper is to gain preview about the role of Indonesian in 2013 curriculum that uses integrated thematic learning by scientific approach in primary schools.AbstrakUntuk menyongsong abad ke-21, model pembelajaran baru dirancang dalam Kurikulum 2013, yang di dalamnya terdapat pergeseran dari siswa diberi tahu menjadi siswa harus aktif mencari tahu ilmu pengetahuan dari berbagai sumber belajar. Dalam hal ini, guru berperan sebagai fasilitator. Dengan demikian, peran bahasa menjadi sangat sentral, karena bahasa harus berada di depan semua mata pelajaran lain. Kurikulum 2013 memberlakukan pembelajaran tematik terpadu yang tidak lagi berbasis mata pelajaran. Berbagai mata pelajaran untuk sekolah dasar (seperti: Agama, PPKN, Bahasa Indonesia, Matematika, IPA, IPS, dan sebagainya) diintegrasi menjadi satu buku. Materi pelajaran tidak disajikan dalam buku mata pelajaran, tetapi dalam buku tema pelajaran, baik tema alam, sosial, maupun budaya. Proses pembelajaran dalam kurikulum baru ini diimplementasikan melalui pendekatan saintifik (mengamati, menanya, menalar, mencoba, dan mengomunikasikan) yang mencakup tiga aspek, yaitu sikap, pengetahuan, dan keterampilan. Lalu, bagaimana peran bahasa Indonesia dalam pembelajaran tematik terpadu melalui pendekatan saintifik di sekolah dasar pada Kurikulum 2013 ini? Melaluimetode deskriptif, yang menjadi tujuan penulisan ini adalah mendapatkan gambaran mengenai peran bahasa Indonesia dalam Kurikulum 2013 yang menggunakan pembelajaran tematik terpadu melalui pendekatan saintifik di sekolah dasar.

To overcome the crisis in the sphere of argumentation studies, the project proposes a logical-cognitive concept of argumentation which is a compound formalized theory that includes formalisms for modeling argumentation of different types, a relevant conceptual framework and a methodology for the use of scientific research in the practice. Three types of argumentation are defined: theoretical (two types) and practical. Theoretical argumentation is a critical discussion of the agents’ knowledge and opinions about facts aimed to substantiate a certain view or to change it – i.e. persuasion. Practical argumentation is a critical discussion of opinions about actions which includes, in addition to the statements about knowledge and opinions, statements of a non-descriptive nature about the agents’ values and intentions to adhere to a certain line of behavior. The study of argumentation needs to focus on the large structures that reflect specifics of the criticism and defense of the positions of the parties. An atom unit of such study is the argument as a statement of reason, while its molecular elements are the argumentative structure of a dispute (frame), a multitude of arguments that express the parties’ positions, a multitude of the agents’ knowledge and opinions that act as the bases for the formation of positions, lines of behavior, etc. Within the framework of this trend, both indefeasible (deductive) and defeasible argumentations can be studied. The argumentation effectiveness can be assessed based on the procedural semantics and using analogues of such logical notions as consistency and completeness. Modern approaches to the argumentation, including those claiming the compound status, can be classified using two methods: based on the substantive and practical criteria. Importance of the research outcomes amounts to the theoretical and methodological role of the new conception of argumentation and the general “umbrella” term argumentation that allows systematizing the manifold research and educational approaches and concepts in this field and is associated with communicative nature of modern social life where efficiency and social success rely on argumentative and narrative competences.

The Baluch, Sunnism and the State in Iran

Since 2002, Sunni jihadi groups have been active in Iranian Baluchistan without managing to plunge the region into chaos. This book suggests that a reason for this, besides Tehran’s military responses, has been the quality of Khomeini and Khamenei’s relationship with a network of South-Asia-educated Sunni ulama (mawlawis) originating from the Sarbaz oasis area, in the south of Baluchistan. Educated in the religiously reformist, socially conservative South Asian Deoband School, which puts the madrasa at the centre of social life, the Sarbazi ulama had taken advantage, in Iranian territory, of the eclipse of Baluch tribal might under the Pahlavi monarchy (1925-79). They emerged then as a bulwark against Soviet influence and progressive ideologies, before rallying to Khomeini in 1979. Since the turn of the twenty-first century, they have been playing the role of a rampart against Salafi propaganda and Saudi intrigues. The book shows that, through their alliance with an Iranian Kurdish-born Muslim-Brother movement and through the promotion of a distinct ‘Sunni vote’, they have since the early 2000s contributed towards – and benefitted from – the defence by the Reformist presidents Khatami (1997-2005) and Ruhani (since 2013) of local democracy and of the minorities’ rights. They endeavoured to help, at the same time, preventing the propagation of jihadism and Sunni radicalisation to Iran – at least until the ISIS/Daesh-claimed attacks of June 2017, in Tehran, shed light on the limits of the Islamic Republic’s strategy of reliance on Deobandi ulama and Muslim-Brother preachers in the country’s Sunni-peopled peripheries.

This chapter asks the questions: ‘what is the Spanish Golden Age and why should we stage its plays now?’ The Royal Shakespeare Company (RSC) Spanish season of 2004–5 came at a particularly ripe time for Golden Age plays to enter the public consciousness. This chapter introduces the Golden Age period and authors whose works were chosen for the season, and the performance traditions from the corrales of Spain to festivals in the United States. The chapter then treats the decision taken by the RSC to initiate a Golden Age season, delves into the play-selection process, and discusses the role of the literal translator in this first step towards a season. Then the chapter looks at ‘the ones that got away’, the plays that almost made the cut for production, and other worthy scripts from this period that deserve consideration for future productions.
