title: Designing a serious game for community-based disease prevention in the Amazon

authors: Luz, Saturnino

subjects: serious games

abstract: Many developing regions around the world rely on community-based healthcare strategies and practices to deal with prevention and control of often neglected diseases, by educating the local population and healthcare professionals, on the mechanisms by which such diseases spread and how they can be controlled. In this paper we describe a multiplayer serious game designed to raise awareness, and foster adoption of preventive measures among local citizens and community-health professionals about Leishmaniosis. We also discuss how the underlying concept for this game and its mechanics have been iteratively designed and developed in collaboration with a group of people with relevant medical and research expertise as well as practical knowledge resulting from working with our target population.

title: Network effect and investor’s perceptions: An empirical investigation

authors: Feroz, Noushad Khan

subjects: Financial information

abstract: Investors’ perceptions, and their understanding related to an investment, are paramount to decision-making in economic and investment settings. Social media is increasingly playing a vital role in influencing investors’ perceptions and investors’ decisions in the financial arena. Social media is a comfortable and easy tool to use. That’s why it has just become a fundamental part of online news sharing and information distribution.

In the first study of this thesis, a network structure is constructed and built social ties circle based on the frequency of communication of investors within the network, and the network size of the investors to develop a comprehensive measurement scale for the social network index. Our findings indicate that the acquisition of information in the social network of investors depends on different components or factors. A significant factor in the network index is the network degree (network connectivity). It implies that network members with higher degrees or connections acquire vast amounts of information. Likewise, investors with larger networks receive enormous amounts of information, notably "following," which is the principal component in terms of network size. As a result, network size appears as the network index's second biggest factor. The smaller contribution comes from social tie circles. However, collectively, all these factors represent the social network index.

In the second study, we argue that the impact of financial information and news on investors’ perceptions is moderated by network factors such as network structure, social ties, and network size of the network. The impact of information on an individual’s perception is also called a social network or network effect. To tackle the moderating role of these network factors, we employed PLS-SEM as a statistical technique. The findings of this study indicate that network connectivity and social ties are crucial for the acquisition of information within the network. The findings of the study also show that network connectivity and social ties circle plays a central role in determining the impact of financial information. Our study further indicates that the impact of financial information and news on investors’ perceptions depends on their theme.

In the third essay of this thesis, we investigate how investors’ perceptions and preferences in terms of trading are influenced by their cultural background and network factors. In this study, we considered the moderating role of network factors in a cross-cultural context. The main subjects of our research datasets are investors who buy and sell shares and/or stocks of companies listed on the stock exchanges of New Zealand and South Korea. In this study, we examined data from 214 retail investors from the New Zealand Stock Exchange (NZX) and South Korea. In comparison to non-kiwi investors, the study's findings show that network factors have a major impact on how information is disseminated among Kiwi investors. The results of this study also demonstrate that network factors' effects differ across cultures and countries.

To conclude, Twitter is a major social media platform that helps investors to connect with their counterparts and obtain financial information through back-and-forth interactions. However, access to information on social networks depends on network structure (network connectivity), social ties circle (family, friends, and colleagues), and network size (number of contact or followers and followings). Twitter also enables prompt dissemination of financial news and information, which can substantially impact investors’ perceptions. However, the impact of information on investors’ perceptions varied cross-culture because of varied network factors.

subjects: climate change adaptation

abstract: Iwi/hapū (tribe/subtribe) governance institutions are increasingly asserting their rangatiratanga (autonomy) to manage climate change risks and meet the well-being of whānau (family)/ hapū/iwi. Howevere, there is a shortange of specific guidance for whānau/hapū/iwi with respect to climate change adaptation and mitigation. We provide a commentary about risk and uncertainty, knowledge gaps, and options for climate change mitigation and adaptation for whānau/hapū/iwi.
