Kuhn is one of the leading philosophers and historians of science that investigated in-depth cases of simultaneous discoveries in science. Although his analysis of the discovery of energy conservation and oxygen did not focus sharply on the priority disputes involved, it is within such contexts that controversy about which scientist was the first to make a discovery takes place. Evidently, Kuhn＇s recourse to historical case studies is a clear departure from the standpoint of traditional mainstream philosophies of science （namely, logical positivism and falsificationism）, which cavalierly dismissed such concerns as irrelevant to philosophical reconstructions of science Challenges to orthodox logistic approaches were prompted by the realisation that the two dominant traditions mentioned above, in their excessive preoccupation with ＂the logical skeleton of science＂, have lost contact with real science. As a contribution to what Michael Polanyi referred to as post-critical philosophy, the present study reanalyses the tension-generating potentials of bipolar values shared by members of scientific communities. It traces the origins of the rebellion against logic-dominated philosophies of science, and identifies different post-positivist approaches that have eme^rged over the years which legitimise broadening the frontiers of the philosophy of science. Consequent upon that, some conflicting values or norms shared by members of scientific communities and how they affect the quest for scientific knowledge are underscored. Using as a case study the acrimonious priority dispute between Isaac Newton and Gottfried Leibniz concerning the discovery of calculus, the paper demonstrates that excessive concern for recognition which sometimes leads to protracted priority disputes tends to bring out the worst kind of behaviours towards colleagues even from the greatest scientists. We submit, by way of conclusion, that despite the heroic （almost god-like） reputation of such scientists, they are human and, therefore, subject to the vicissitudes of emotional turbulence just like everyone else.展开更多

However, this information usually has conflicts. In order to resolve conflicts and get the true information, truth discovery has been proposed and received widespread attention. Many algorithms have been proposed to adapt to different scenarios. This paper aims to investigate these algorithms and summarize them from the perspective of algorithm models and specific concepts. Some classic datasets and evaluation metrics are given in this paper. Some future directions for readers are also provided to better understand the field of truth discovery.展开更多

Evidence is divided into three categories:believable evidence, non-conflicting evidence and conflicting evidence. The influences of these three categories of evidences on fusion results when discounted are analyzed respectively. On these bases, the evidence distance and the conjunctive conflict are utilized in sequence to recognize the believable evidence and non-conflicting evidence. The discounting factors of these two categories of evidences are set to one, which keeps the evidences support the true hypothesis to the greatest degree, and makes the fusion results focus onto the true hypothesis. Examples of some missile fault diagnosis show that the new method can effectively fuse the conflicting evidences, and is suited to fuse the relievable evidences. The new method improves the reliability and rationality of fusion results compared with traditional methods.展开更多

Purposive sampling was adopted, in which focus group discussions, key informant interviews, semi-structured interviews, and snowball sampling were used for data collection. Focus group discussions were conducted with a total of 20 local associations involved in forest and wildlife management, Bantu traditional councils and the Baka community. Key informant interviews were conducted with local and international NGOs, forest exploitation and Sport hunting (Safari) enterprises and local public administrations that had working rapports with village communities around the BBNP. Information was generally sought on the role of stakeholders in forest management, in terms of use, protection, policy enforcement, challenges encountered in their activities and their relationships with other stakeholders. Actor linkage matrix was used to establish the relationships between different stakeholders. The identified stakeholder groups included the local community, State, international and local NGOs, economic operators (forest exploitation and sport hunting enterprises), and also the rules guiding their activities. Conflicts were rife between the community and the other stakeholders with regard to resource accessibility and use, whereas intra-community conflicts mostly resulted from cases of corruption and embezzlement linked to benefits sharing. Cases of collaboration among all the stakeholders were mostly related to anti-poaching patrols and setting of forest concession limits. There is a need to bring all stakeholders on the same platform, such as in a consultation workshop, to get their perceptions on building trust, conflict resolution and genuine collaboration in resources management.展开更多
