<p>This article is an attempt to explore the inclusion and the use of superstitious elements in Mark Twain’s novel <em>The Adventures of Huckleberry Finn</em> (1884) and Shakespeare’s play <em>Macbeth</em> (1611). Superstition involves a deep belief in the magic and the occult, to almost to an extent of obsession, which is contrary to realism. Through the analytical and psychological approaches, this paper tries to shed light on Twain’s and Shakespeare’s use of supernaturalism in their respective stories, and the extent the main characters are influenced by it. A glance at both stories reveals that characters are highly affected by superstitions, more than they are influenced by their religious beliefs, or other social factors and values. The researcher also tries to explore the role played by superstition, represented by fate and the supernatural in determining the course of actions characters undertake in both dramas. The paper concluded that the people who lived in the past were superstitious to an extent of letting magic, omens; signs, etc. affect and determine their lives; actions and future decisions. They determine their destiny and make it very difficult for them to avoid it, alter it or think rationally and independently. And that, man’s actions are not isolated, but closely connected to the various forces operating in the universe.</p>

The article examines the conquest of the New World in the focus of interaction of different types of thinking in the clash and conflict of two civilizations, which develop in different ways and which are at different levels of social and economic development. The result of this clash was the destruction of the material, spiritual and intellectual traditions of indigenous cultures that existed on the American continent. The conquest of America is one of the most revealing examples of the clash of civilizations, analyzing which, with particular clarity, one can observe contradictions between different types of world perception. The answer to questions about what kind of knowledge Nahua-speaking people possessed, what role knowledge played in their society, who was the creator, carrier and translator of knowledge about the world, reveals one of the main reasons that led to a rapid and irretrievable destruction of culture of “metaphors and numbers.” The author reveals the role of Catholic monks in preserving the spiritual, scientific and philosophical heritage of the Mexican culture, thanks to which we have the opportunity to touch the thought of the Nahua people, existing not in the form of traditional texts but in the form of an oral tradition, which accompanied visual images of graphic semantic writing. It shows how important the system of education and upbringing in the society of pre-Columbian Mexico was, how it solved the tasks of preparing young people for the performance of social functions. The destruction, as a result of the con- quest, of the system that regulated the daily life of each person and determined the ultimate destiny of the people in the shortest possible time led to the death of the entire civilization.

Kongkil music was created in 1933 by Eyang Toinangun as a means of gathering the people of Bungkal Village as an effort to resist the Dutch invaders. Kongkil music is an ensemble consisting of instruments of kongkil, kedhang, saron, kethuk, kenong, kempul and gong. In the beginning, Kongkil's music brought songs created by its members with the theme of passion-building, because there was no legacy of the old repertoire of the predecessors. There was an innovation in the form of repertoire changes since 1975, namely bringing dolanan gendhing. Around 2000, Kongkil's music was in a vacuum, then it was revived in 2012 with a new repertoire that presented lancaran and langgam gendhing. The research entitled "The Form and Change of Kongkil Music Function in Bungkal Village, Ponorogo Regency" uses the concept of Edy Sedyawati's thought that changes in social structure and values will cause physical changes and the role of art itself in society. It also causes changes in the structure of forms. These changes cannot be avoided if the art is willing to live within the society. This study uses descriptive qualitative analysis methods.  From this study, it found several things related to the Kongkil Martapura music group, including: (1) History and regeneration of the Kongkil Martapura music group, (2) the forms of performances, instruments and repertoires presented, (3) the factors driving changes in function and its impact on intellectuals and contextual.


This chapter begins by explaining the nature of innovation and basic models of innovation, including key stages in the process of innovation. As the construction industry is often regarded as different from other industries given its unique characteristics, innovation in construction is discussed in terms of motivation for the industry’s Small and Medium Enterprises (SME) to innovate, key organizational capabilities required for innovation, and external and internal factors critical to successful innovation. In addition, the common enablers, barriers, motivators, and outcomes of innovation in the construction industry are discussed. Understandably, as the role of clients in the construction industry is vital in many ways in driving to improve performance of projects, the chapter focuses on their role in driving innovation. The different types and categories of clients are described, as well as their roles in different types of innovations, and at different stages of innovation. The chapter also covers the role of technology in innovation and, more specifically, Computer-Aided Design (CAD) as an important technological innovation for the construction industry. At the organizational level, factors that can affect the rate of diffusion of a new technology within construction SMEs are explained. At the project level, factors that impact on innovative IT implementation and diffusion are also explained. Next, innovation and its role in enabling construction businesses to gain competitive advantages are discussed. The need to classify construction innovation and how it can encourage businesses to innovate by adopting appropriate strategies are explained through a case of Singapore’s construction industry. In addition, the need for and application of strategies, policies, and procedures to deal with IT in managing construction site processes are described in a study of UK’s leading construction companies. On achieving continuous improvement as a whole for the industry, issues relating to innovation, including reasons for the lack of it, are discussed and presented. On managing change, focus on the “people” factor of innovation, especially the need to develop capability of staff to use new technologies, is given. The chapter concludes with a summary of the main points covered on change through innovation and customer-orientation.

Abstract The problem of improving the voltage profile and reducing power loss in electrical networks must be solved in an optimal manner. This paper deals with comparative study of Genetic Algorithm (GA) and Differential Evolution (DE) based algorithm for the optimal allocation of multiple FACTS (Flexible AC Transmission System) devices in an interconnected power system for the economic operation as well as to enhance loadability of lines. Proper placement of FACTS devices like Static VAr Compensator (SVC), Thyristor Controlled Switched Capacitor (TCSC) and controlling reactive generations of the generators and transformer tap settings simultaneously improves the system performance greatly using the proposed approach. These GA & DE based methods are applied on standard IEEE 30 bus system. The system is reactively loaded starting from base to 200% of base load. FACTS devices are installed in the different locations of the power system and system performance is observed with and without FACTS devices. First, the locations, where the FACTS devices to be placed is determined by calculating active and reactive power flows in the lines. GA and DE based algorithm is then applied to find the amount of magnitudes of the FACTS devices. Finally the comparison between these two techniques for the placement of FACTS devices are presented.

This is an English translation with some expansion of the article originally published in Japanese as a university bulletin in 2009. Previous research has found both differences and similarities between ijime in Japan and bullying in England. Bullying is often by pupils in different classes or higher year groups whom the victim does not know very well; ijime is often by victims’ classmates whom the victim knows very well. However, it has not been shown whether these differences are found for all types of bullying, or how they relate to friendships generally and the impact of differing school systems. We aimed to see whether previously found differences between ijime and bullying could be replicated, and, if so, whether they held for six different types of victimization, and whether friendship characteristics were consistent with explaining why they occur. To investigate the role of friendships and their location, 1036 Japanese and 931 English secondary school pupils participated in a comparative study of perceptions of bullying and ijime. The previous differences were confirmed and found to hold irrespective of type of bullying. Japanese pupils mainly formed friendships on a class basis, English pupils on a broader basis including pupils in different years. In school, English pupils spent much time in the playground with their friends and saw this as a likely venue for bullying, whereas Japanese pupils spent more time in the classroom and saw this as a likely venue for ijime. The difference in friendship formation, together with differences in the organization of class-based teaching in the two countries, are hypothesized to play a significant role in explaining some differences between bullying and ijime.

ABSTRACT In this paper, we examine the role of budgets as a central instrument within the management control system (MCS) in a creative context. In particular we investigate whether creative firms characterized by different kinds of creativity use their budgets in a similar way. We hereby distinguish between expected creativity (for open, self-discovered problems) and responsive creativity (for closed, presented problems) (Unsworth 2001) and investigate the interactive versus diagnostic use of budgets (Simons 1990, 1991, 1995). Based on a comparative study involving four creative firms, we find that creative firms, being mainly characterized by expected creativity, use their budgets in a more interactive way. In creative firms in which responsive creativity is most important, the budgets are used in a rather diagnostic way. This study contributes to the management control literature by acknowledging that a diagnostic use of budgets does not per se stifle creativity. Instead, it is important to understand that the specific creative context might have implications for the way in which MCS instruments are used to sustain the creative process.

Understanding the role of youth workers and promoting an accurate representation of these professionals and their work requires a focus on current research, practice, and policies that capture the challenges and opportunities of the youth development workforce. An overview of this special issue of the Journal of Youth Development examines efforts to support individual youth workers, strategies organizations use to prepare and assist youth workers, and system approaches to building the capacity of the workforce in key areas such as quality and social emotional learning, and concludes with an encapsulation of interviews with 10 key leaders nationwide. They identified the overarching task as one of identification of the elements that can make the field cohesive across the different settings and programs, while supporting youth in their growth through experiences that are rooted in the science of learning and development. Finally, this special issue offers the opportunity to better understand the youth workers, examine different types of professional development pathways, explore the role that systems can play in support of these workers, and reflect on the challenges and opportunities raised by key leaders in the profession.
