Batavia, Dutch East Indies
Batavia was the capital of the Dutch East Indies. The area corresponds to present-day Jakarta, Indonesia. Batavia can refer to the city proper or its suburbs and hinterland, the , which included the much larger area of the Residency of Batavia in the present-day Indonesian provinces of Jakarta, Banten and West Java. The founding of Batavia by the Dutch in 1619, on the site of the ruins of History of Jakarta, Jayakarta, led to the establishment of a Dutch colony; Batavia became the center of the Dutch East India Company's trading network in Asia. Monopolies on local produce were augmented by non-indigenous cash crops. To safeguard their commercial interests, the company and the colonial administration absorbed surrounding territory. Batavia is on the north coast of Java, in a sheltered bay, on a land of marshland and hills crisscrossed with canals. The city had two centers: Kota Tua Jakarta, Oud Batavia (the oldest part of the city) and Sawah Besar, Weltevreden (the relatively n ...

Sociology
Sociology is the scientific study of human society that focuses on society, human social behavior, patterns of Interpersonal ties, social relationships, social interaction, and aspects of culture associated with everyday life. The term sociology was coined in the late 18th century to describe the scientific study of society. Regarded as a part of both the social sciences and humanities, sociology uses various methods of Empirical research, empirical investigation and critical analysis to develop a body of knowledge about social order and social change. Sociological subject matter ranges from Microsociology, micro-level analyses of individual interaction and agency (sociology), agency to Macrosociology, macro-level analyses of social systems and social structure. Applied sociological research may be applied directly to social policy and welfare, whereas Theory, theoretical approaches may focus on the understanding of social processes and phenomenology (sociology), phenomenologic ...

Systems Theory
Systems theory is the Transdisciplinarity, transdisciplinary study of systems, i.e. cohesive groups of interrelated, interdependent components that can be natural or artificial. Every system has causal boundaries, is influenced by its context, defined by its structure, function and role, and expressed through its relations with other systems. A system is "more than the sum of its parts" when it expresses synergy or emergent behavior. Changing one component of a system may affect other components or the whole system. It may be possible to predict these changes in patterns of behavior. For systems that learn and adapt, the growth and the degree of adaptation depend upon how well the system is engaged with its environment and other contexts influencing its organization. Some systems support other systems, maintaining the other system to prevent failure. The goals of systems theory are to model a system's dynamics, Theory of constraints, constraints, conditions, and relations; and to ...

Scientometrics
Scientometrics is a subfield of informetrics that studies quantitative aspects of scholarly literature. Major research issues include the measurement of the impact of research papers and academic journals, the understanding of scientific citations, and the use of such measurements in policy and management contexts. Leydesdorff, L. and Milojevic, S., "ScientometricsarXiv:1208.4566(2013), forthcoming in: Lynch, M. (editor), ''International Encyclopedia of Social and Behavioral Sciences'' subsection 85030. (2015) In practice there is a significant overlap between scientometrics and other scientific fields such as information systems, information science, science of science policy, sociology of science, and metascience. Critics have argued that overreliance on scientometrics has created a system of perverse incentives, producing a publish or perish environment that leads to low-quality research. Historical development Modern scientometrics is mostly based on the work of Dere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Network Analysis
Social network analysis (SNA) is the process of investigating social structures through the use of networks and graph theory. It characterizes networked structures in terms of ''nodes'' (individual actors, people, or things within the network) and the ''ties'', ''edges'', or ''links'' (relationships or interactions) that connect them. Examples of social structures commonly visualized through social network analysis include social media networks, meme proliferation, information circulation, friendship and acquaintance networks, business networks, knowledge networks, difficult working relationships, collaboration graphs, kinship, disease transmission, and sexual relationships. These networks are often visualized through '' sociograms'' in which nodes are represented as points and ties are represented as lines. These visualizations provide a means of qualitatively assessing networks by varying the visual representation of their nodes and edges to reflect attributes of inter ...

Philosophy Of Science
Philosophy of science is the branch of philosophy concerned with the foundations, methods, and implications of science. Amongst its central questions are the difference between science and non-science, the reliability of scientific theories, and the ultimate purpose and meaning of science as a human endeavour. Philosophy of science focuses on metaphysical, epistemic and semantic aspects of scientific practice, and overlaps with metaphysics, ontology, logic, and epistemology, for example, when it explores the relationship between science and the concept of truth. Philosophy of science is both a theoretical and empirical discipline, relying on philosophical theorising as well as meta-studies of scientific practice. Ethical issues such as bioethics and scientific misconduct are often considered ethics or science studies rather than the philosophy of science. Many of the central problems concerned with the philosophy of science lack contemporary consensus, including whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dutch Systems Group
The Dutch Systems Group, or Netherlands Society for Systems Research or , is a society in the Netherlands for systems theory, and its applications. Systems theoretical problems the society focuses on are, for example evolution, innovation, selection, variation, translation, participation and methodological innovation. Overview The Dutch Systems Group was initiated by Albert Hanken and Gerard de Zeeuw and others in 1970. The activities of the Dutch Systems Group, according to de Zeeuw (2006), made an important contribution to the introduction of the area of systems studies in the Netherlands. Other early participant have been Felix Geyer, Henk Koppelaar, Ton de Leeuw and Geert Jan Olsder. In the beginning of the 1980s the Dutch Systems Group cofounded the International Federation for Systems Research together with the international American based Society for General Systems Research and the Austrian Society for Cybernetic Studies. During the 1970s the Dutch Systems Group pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
