Adequate Measurement

The measurement and analysis of the authority and influence exercised by a person in an organization or social network, be it formal or informal, has been the subject of numerous researches in several fields of science. At present, this phenomenon has taken on greater connotation due to its irruption in the digital space and the importance of having this knowledge for decision-making in spheres such as politics, education and the dissemination of information. In this research, an algorithm was developed for the measurement and analysis of the authority and influence of users in social and professional networks. The study had a mixed approach, with correlational scope and experimental design. A random sample n = 30 specialists was used, which was carried out between May 2019 and October 2020. It was based on the premise that, in order to carry out an adequate measurement and analysis of authority and influence, the structure of the graph must be considered that represents the social network and the interactions that occur between users. As a result, the Total Authority algorithm is developed, a computer tool for the generation of the graph and a case study, which evaluates its relevance, operation and applicability, which shows satisfactory results in its comparison with the HITS algorithm and a sociogram.

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.

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.

<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>

Despite the growing interest in extreme sports around the world, researchers have rarely investigated the complex factors that have led to a developed commitment to extreme sports in recent years. Precisely, the social identity of ultramarathoners remains a research niche. The aim of the article is to analyze the impact of a sports event on shaping social identity of ultramarathon runners on the example of Karkonosze Winter Ultramarathon (held in Poland). The qualitative method used in the article—interviews with runners—made it possible to examine the factors that create social identity, among which the motives for participation, sports subculture, and the authenticity of the experience play a key role. The first part of the article describes the theoretical aspects of social identity in sport. The second, empirical part presents the research results supplemented by the statements of the contestants. In this case, the subject of analysis is the motives for participation in a winter ultramarathon and their characteristics. Lastly, the article analyzes the subculture of ultramarathoners and the experience of contestants’ authenticity. The investigated winter ultramarathon created the perfect space for creation, deepening and celebrating the social identity of ultramarathoners assessed as a value in itself. The article enriches the present knowledge about the motivation of ultramarathoners because, unlike the results of quantitative research, it presents in-depth responses of runners who were not always concerned by existing research questionnaires.

Accountability in providing public administration to the poor people in the Social Department of Makassar. This study was qualitative case study approach, while the instruments were the researchers themselves. This study showed that the accountability in providing public administration to the poor people had not run optimally. There were various approaches and alleviation programs for poverty that had not been able to change significantly. There was no continuous program during the official turnover. If the official was changed, then the policy would be changed, thus the programs were ineffective to minimize the poverty in Makassar. The policies and the supports were necessary from all the elements of construction and the involvement of entrepreneurs like stakeholders and community leaders. The government is necessary to take a role in uniting and bridging these issues. In addition, the strategic planning was necessary to involve society, not only as objects of development but also to be involved as the subject of development to alleviate the poverty in Makassar.
