Editorial

The production of yet another new journal requires some explanation although there need be no apology. The Earth Science Journal is intended to answer the need, caused by increasing specialisation by other journals, for a place in which to publish articles and research reports which are of wide interest to earth scientists, and which cross the boundaries of the traditional disciplines. To this end contributions of reports on research, essays, notes and letters will be welcomed from geologists, geomorphologists, pedologists, climatologists, oceanographers, ecologists and physical geographers

From peasant society to manufacturing society

Since the early 1990's when the first cases of HIV were found in Vietnam, the number of people infected with HIV has been increasing. Over half of the Vietnamese population is under the age of 25 and 78.9% of the reported cases of HIV are people between the ages of 20 and 39. This thesis work has been undertaken to evaluate whether there is a need to focus more on the youth in terms of prevention within HIV and AIDS related to the move from a peasant society to a more industrialised society. To investigate this, a literature desk study was carried out supported by key informant interviews and a small questionnaire. It was found that specifically the HIV and AIDS law, stigma, discrimination, gender roles, and risk-behaviour of migrants and the Vietnamese youth were important factors linked with vulnerability and livelihood change after doi moi. Although more research on a national level on the subject is needed, the findings indicate that changes have happened since doi moi which influences the linkages between livelihood change and HIV and AIDS vulnerability among the youth in Vietnam

Digital Society Ecosystem Impact on Creative Industry

Industry 4.0 phenomenon has emerged since many technological breakthroughs developed in the past decades. Human well-being behavior are basically influenced by the digital technology. The current customers incline the need for customized products. This situation drive the production paradigm shift from the mass production to the individual production. This paradigm shift force companies to own more resources. Companies’ collaboration is a way to win the competition. Industrial revolution era bring the fact that dominant economic activity is coming from a strong business ecosystem. The major impact of digitalization is faced by the creative industries, an industry priority and a \u27laboratory\u27 for studying economic transformation and modern society. This paper will review the digitalization in industry 4.0 era, business ecosystem and society shift, and the digitalization impact on creative industry.

Limited Attention and Centrality in Social Networks

How does one find important or influential people in an online social network? Researchers have proposed a variety of centrality measures to identify individuals that are, for example, often visited by a random walk, infected in an epidemic, or receive many messages from friends. Recent research suggests that a social media users' capacity to respond to an incoming message is constrained by their finite attention, which they divide over all incoming information, i.e., information sent by users they follow. We propose a new measure of centrality --- limited-attention version of Bonacich's Alpha-centrality --- that models the effect of limited attention on epidemic diffusion. The new measure describes a process in which nodes broadcast messages to their out-neighbors, but the neighbors' ability to receive the message depends on the number of in-neighbors they have. We evaluate the proposed measure on real-world online social networks and show that it can better reproduce an empirical influence ranking of users than other popular centrality measures.Comment: in Proceedings of International Conference on Social Intelligence and Technology (SOCIETY2013
