Collusive bidding has been an insidious issue in the construction industry. Bidders initiate collusive networks of various sizes to win market shares. The popularity of collusive bidding networks affects market fairness and erodes the interests of market players. Although considerable research efforts were made to diagnose collusive bidding networks, there remains a gap in knowledge regarding the relationships bid riggers use to engage in the networks. Therefore, this study used the social network method, where two hundred sixteen collusion cases were collected from China to test these relationships. The results show that collusive bidding networks were characterized by sparseness, a small scale, a high concentration, and strong randomness. Three types of collusive bidding networks were also detected: contractual, spontaneous, and shadow. Furthermore, these collusive bidding networks had discrepancies regarding participants’ identities, forms of collusive bids, and the determination of bid winners. It was found that the proposed social network model of deliberating bid riggers’ relationships lays a solid foundation for the detection of collusive bidding in the construction sector.

Social Network Position

Intergroup violence is common among humans worldwide. To assess how within-group social dynamics contribute to risky, between-group conflict, we conducted a 3-y longitudinal study of the formation of raiding parties among the Nyangatom, a group of East African nomadic pastoralists currently engaged in small-scale warfare. We also mapped the social network structure of potential male raiders. Here, we show that the initiation of raids depends on the presence of specific leaders who tend to participate in many raids, to have more friends, and to occupy more central positions in the network. However, despite the different structural position of raid leaders, raid participants are recruited from the whole population, not just from the direct friends of leaders. An individual’s decision to participate in a raid is strongly associated with the individual’s social network position in relation to other participants. Moreover, nonleaders have a larger total impact on raid participation than leaders, despite leaders’ greater connectivity. Thus, we find that leaders matter more for raid initiation than participant mobilization. Social networks may play a role in supporting risky collective action, amplify the emergence of raiding parties, and hence facilitate intergroup violence in small-scale societies.

Campaigns nowadays are oftenly carried through social medias, including campaigns concerning the environment. Based on previous studies, effectivity of campaigns through social medias were affected by many factors, such as the activity of the online administrator, additional socialization that were carried off- line, and also the involvement of the active followers in social medias. However, this paper views environmental campaign in social medias could be effective if viewed from another side,that is social network. This study sees how social network can improve the effectivity of environmental campaigns in social medias,therefore it’s safe to say that this study brings an addition to previous studies related tofactors that influenced the effectivity of environmental campaigns that utilized social medias as a channel of communication. The method used for this paper is qualitative method, with case study on Melawan Asap (Fight the Haze) campaign initiated by BEM UI (Executive Board of Students of University of Indonesia) in 2015 to form an alliance consisting several organizations from inside and outside of the university. Collection of data for this study was done with in-depth interviews with certain informants, based on a criteria established previously by the author, beside an observation upon social media accounts that were used for Fight the Haze campaign. The result shows that the involvement of networks in social media affects the effectivity of Fight the Haze campaign. Also, the social relation between organizations that are united under the alliance of Fight the Haze campaign are based on sentimental network.Kampanye kian marak dilakukan dengan menggunakan media sosial, tidak terkecuali kampanye lingkungan. Berdasarkan kajian-kajian sebelumnya, keefektifan kampanye dengan menggunakan media sosial dipengaruhi oleh berbagai faktor seperti adanya administrator online yang aktif, adanya sosialisasi tambahan yang dilakukan secara offline, dan juga terlibatnya pengikut/followers di media sosial secara aktif. Namun, tulisanini melihat kampanye lingkungan di media sosial dapat efektif dari sisi lain yaitu dari jaringan sosial. Kajian ini melihat bagaimana jaringan sosial berperan dalam membuat efektif kampanye lingkungan di media sosial, sehingga dapat dikatakan bahwa kajian ini menambahkan penemuan dari kajian-kajian sebelumnya yang berbicara mengenai faktor yang membuat efektif kampanye lingkungan dengan menggunakan media sosial sebagai media komunikasinya. Metode yang digunakan dalam tulisan ini adalah metode kualitatif dengan studi kasus pada kampanye melawan asap yang diinisiatori oleh BEM UI 2015 untuk membentuk sebuah aliansi dengan menggandeng beberapa organisasi di UI dan juga dari luar UI. Pengambilan data dalam studi ini dilakukan melalui wawancara mendalam dengan informan- informan tertentu berdasarkan kriteria yang penulis tetapkan dan melakukan observasi terhadap akun media sosial yang digunakan untuk menyebarluaskan kampanye melawan asap. Hasil kajian ini menunjukkan bahwa keterlibatan peran jaringan di media sosial mempengaruhi efektifitas kampanye melawan asap, serta hubungan sosial antar organisasi yang tergabung dalam aliansi gerakan melawan asap terbentuk berdasarkan jaringan perasaan/sentiment.

The incorporation of digital sources from online social media into historical research brings great opportunities, although it is not without technological challenges. The huge amount of information that can be obtained from these platforms obliges us to resort to the use of quantitative methodologies in which algorithms have special relevance, especially regarding network analysis and data mining. The Recovery of Historical Memory in Spain on the social network Twitter will be analysed in this article. An open-code tool called T-Hoarder was used; it is based on objectivity, transparency and knowledge-sharing. It has been in use since 2012.

<p>While the potential of social networking sites to contribute to educational endeavors is highlighted by researchers and practitioners alike, empirical evidence on the use of such sites for formal online learning is scant. To fill this gap in the literature, we present a case study of learners’ perspectives and experiences in an online course taught using the Elgg online social network. Findings from this study indicate that learners enjoyed and appreciated both the social learning experience afforded by the online social network and supported one another in their learning, enhancing their own and other students’ experiences. Conversely, results also indicate that students limited their participation to course-related and graded activities, exhibiting little use of social networking and sharing. Additionally, learners needed support in managing the expanded amount of information available to them and devised strategies and “workarounds” to manage their time and participation.<br /><strong></strong></p>

The uncertainty and complexity of natural hazards put forward new requirements for emergency management systems. In order to deal with natural hazards effectively, it is important to build a cooperative network between government organizations and social organizations. The social network analysis method is adopted, the April 2013 Ya’an China earthquake is taken as a case study, the institutionalized emergency organization network before the disaster and the actual response organization network after the disaster are analyzed, and centrality, between centrality, closeness centrality and core-periphery are calculated. Through qualitative and quantitative research, the functions of social organization in the process of natural hazards emergency relief are revealed, the role orientation of social organization in the emergency management network is analyzed, and the influence factors of the social organization participation in the natural hazards relief is pointed out. Research results will help to promote the cooperation between social organization and government, and improve the efficiency of natural hazards emergency relief.

The authors introduce the Social Land Programmes, Hungary. Social Land Programmes aim to strengthen self-sufficiency and reduce reliance on social aid by helping people with no financial means to engage with small-scale agriculture. The case study investigated eight rural communities participating in a Social Land Programme. Innovative features include bottom up organisation designed and carried out locally (in contrast to top-down public employment programmes in Hungary). For local leaders, producing food and improving living standard are its main points. They also see various other benefits that include improving the social and physical environment and passing on positive role models within the family. However, they consider national goals of increased employment and self-sustainability to be over optimistic.

Social resilience is an essential aspect of sustainability in environmental management, especially in poor resource-dependent communities. To better understand the dynamics of social resilience, we have conducted a primarily qualitative study of communities dependent on hilsa fishing in two coastal villages in southern Bangladesh. This study applies concepts of social-ecological system (SES), social resilience and co-management in outlining our qualitative data and framing its interpretation. Our findings show that while the establishment of hilsa sanctuary areas has enhanced the previously low ecological sustainability of local small-scale fishing, the management of this program has challenged the social resilience of hilsa fishers by creating new inequalities in the distribution of power and privilege, in terms of the ways in which seasonal fishing bans are enforced and compensation for income loss during the ban periods is distributed. Based on our findings, we suggest specific measures for strengthening social resilience at the local level, including building community networks, developing community infrastructures, updating existing rules and regulations, providing alternative means of generating income for fishers during the crisis periods (e.g. natural disasters and fishing ban periods) and more active sharing of responsibility between stakeholders and government for management of the hilsa fishery. These findings are also applicable to understanding the issues beyond rules and regulations that co-management arrangements need to address in order to be successful and to enhancing the function of co-management arrangements in improving social resilience within resource-dependent communities.
