Ethnomedicinal Plants of Hasankeyf (Batman-Turkey)

Hasankeyf is an ancient city, dating back to more than 10,000 years, in the Southeast Anatolia Region of Turkey. The area is separated by the Tigris River on both sides and located in the Batman province. However, as a result of a dam project, in February 2020, this ancient city and some of its surrounding villages were totally flooded. The residents were moved to new settlements. This study aimed to prevent the possible loss of ethnomedicinal knowledge of plants due to migration as well as to pass on this knowledge to the future generations. The field studies were conducted between March 2017 and November 2019 in the city center and 22 rural settlements of Hasankeyf. Also, the areas where intensive migration was experienced were visited frequently. Interviews were conducted with a total of 131 participants (76 women and 55 men) while gathering plants with them. Information was collected through interviews and questionnaires. The results were analyzed by quantitative indices of information consensus factor (FIC) and use value (UV). A total of 94 plant taxa belonging to 40 families were identified in the study area. The most common medicinal plant families are Lamiaceae (13), Asteraceae (8), Rosaceae (6), Malvaceae (6), Amaryllidaceae (5), Brassicaceae (4), and Solanaceae (4). The most common preparations were infusion, fresh application, and crushing. The taxa having the highest count of use value (UV) were Teucrium polium, Matricaria aurea, Urtica dioica, Mentha longifolia, and Quercus brantii. Besides, the recorded ailments were grouped into categories based on information provided by the interviewees. The most important use categories among the informants were diabetes, gastrointestinal disorders, respiratory disorders, and dermatological disorders. The present study represents the first medical-ethnobotanical documentation and analysis of the traditional use of medicinal plants in Hasankeyf.

Dynamic Adaptive Cross-Chain Trading Mode for Multi-Microgrid Joint Operation

The emerging blockchain technology has injected new vitality into the energy market, especially the peer-to-peer power trading of microgrid systems. However, with the increase of energy blockchain projects, the difficulty of data communication and value islands between blockchain networks have become open issues. Thus, in this paper, we propose a dynamic adaptive cross-chain trading mode for multi-microgrid joint operation. The novelty is to design a proof of credit threshold consensus mechanism to achieve effective information verification. This consensus mechanism can ensure the adaptive consistency of cross-chain information without changing the existing blockchain architecture of each system. At the same time, we design a corresponding key management interoperability protocol based on RSA algorithm and Chinese remainder theorem, which can realize data transfer and information consensus for cross-chain transactions. The theoretical analysis verifies that the cross-chain communication information is effective and the system is able to protect against the attack of malicious nodes. Finally, a cross-chain simulation experiment is established to analyze the operation efficiency. The result shows that this cross-chain trading takes place within seconds, which basically meets the response requirements for multi-microgrid joint operation.

Public policy management by actors’ endowment

As shown in this chapter, Action Plans (AP) can be considered as means of improving both the efficiency and effectiveness of public policies. Such plans aim to coordinate and target the production of administrative outputs in terms of defining (functional, temporal, spatial or social) priorities. The chapter shows that the ‘service level agreements’ (French: mandat/contrat de prestation; German: Leistungsvertrag), which are increasingly used in Switzerland, can be in interpreted as specific action plans that attempt to control public action by means of specific allocations of public action resources. Initially aimed at limiting state intervention (liberal state), such agreements have become general instruments for the management of public policies by identifying (quantitatively or qualitatively determined) objectives and related resources and outputs to be produced by various public agencies. The chapter shows, however, that such agreements take little or no account of the effectiveness in terms of the results (outcomes) of public policies. Hence, new public management reforms still lack adequate management or control of their (claimed) capacity for steering problem-solving through public policies by means of the allocation of budgets of both very familiar (Law, Time, Personnel, Money) and still not entirely recognized resources (Organization, Information, Consensus, Political Support).
