The Sebatik Island is one of the main cocoa-producing regions in Indonesia, but its productivity has been reported to be below the potential production volume. Therefore, this study aims to evaluate the sustainability index for smallholder cocoa plantations on the Sebatik Island using the multidimensional scaling (MDS), known as the RAP- SEBATIK (rapid appraisal for cocoa on Sebatik Island) that adopts from the RAPFISH (Rapid Appraisal for Fisheries). The MDS was used to evaluate the sustainability status of cocoa across six dimensions, while the leverage analysis was applied to identify the status of the most influential attributes of each dimension. The results showed that the average sustainability index value for such dimensions as ecological, economic, sociocultural, infrastructural and technological, law and institutional, as well as defence and security was 46.23, 48.58, 75.20, 40.49, 36.39, and 36.39%, respectively, based on the current conditions. According to these findings, only the sociocultural dimension was sustainable in smallholder cocoa plantations on the Sebatik Island. The main attributes that need improvement for the sake of sustainability apply to the following dimensions: ecological, economic, sociocultural, infrastructure and technology, law and institutional, as well as defence and security. Attributes that need intervention are the average age of cocoa, the community’s level of formal education, fertilisers application for cocoa, the operation of a shop for agricultural production facilities, and defence and security facilities and infrastructure.

With the upcoming implementation of the centralized capacity market in Poland, capacity auctions will be organized where domestic power companies will offer their available capacities. It is assumed that bidding will be auctioned according to the so called descending clock auction system with uniform-price (Pay-as-Clear), which will lead to the market equilibrium price. Some analysts, however, are of the view that it is more appropriate to organize capacity auctions in the Pay-as-Bid formula, as this system should lead to lower prices that those of Pay-as-Clear, hence lower costs of capacity purchase. However, this opinion does not confirm the practice – theoretical considerations do not take into account such important factors as the behavior of market players and the tendency of bidders to accept a higher risk or the lack of access to advanced analyses, and thus better information for all market participants. This paper presents a hypothetical calculation of the prices in the centralized capacity market using Monte Carlo simulations. The results of the study confirm that the price level for the Pay-as-Bid system, due to the asymmetry of information and the level of concentration of the power generation sector in Poland would lead to higher prices than for the Pay-as-Clear system on average by approximately 2.5%. The implementation of the PAB system would, therefore, be less efficient to electricity consumers.

In the authors’ opinion, the issue of incorrectly functioning water insulation of foundation walls in the existing buildings in Poland is currently rather common. The paper includes a multicriteria analysis aimed at arranging the selected options of the foundation wall vertical water insulation technology in an existing model historic building using the weighted sum, entropy and AHP methods. Each of the studied solutions was evaluated in terms of the following criteria: costs of construction works, time of execution of construction works, popularity of using particular insulation options by other contractors, durability of the executed insulation and the degree of nuisance of the executed works

Studiando le vicende della spiritualit polacca si pu notare che fin dallinizio, cio dal momento dellinserimento della Polonia nellEuropa cristiana, erano presenti in essa alcune correnti della spiritualit europea. Un forte influsso sulla nascita e sullo sviluppo della spiritualit polacca avevano gli ordini religiosi. Tra le dimensioni della spiritualit europea coltivate in Polonia una particolare attenzione merita la dimensione cristocentrica e mariana.

Roman Micnas was a distinguished Polish physicist, well known for his works in the field of condensed matter theory and statistical physics. One of his best known achievements is development of theory of superconductivity with local electron pairing. He also published a number of important contributions to the theory of magnetism, theory of phase transitions, and theory of ultracold atoms on optical lattices. His more than 140 publications were cited over 3200 times by other authors. He graduated at the Faculty of Mathematics, Physics and Chemistry of Adam Mickiewicz University (AMU) in 1970, where he hold a position until his passing away on 13 January 2022. He received PhD in 1978, habilitation in 1988, and became Professor in 1990. In the Faculty of Physics of AMU he was the head of Solid State Theory Division in years 1998–2018. For his development of theory of superconductivity with local electron pairing he was awarded, together with Stanisław Robaszkiewicz, the Marie Skłodowska-Curie Scientific Prize of the Polish Academy of Sciences (PAS) in 1989. In 1994 he became Corresponding Member of PAS, and in 2016 – Ordinary Member. He served a number of important functions in PAS, among others he was a member of Committee for Physics of PAS, and since 2015 a Dean of Division III of Exact Sciences and Earth Sciences of PAS. He was a member of several scientific societies: Polish Physical Society, European Physical Society, American Physical Society and American Association for Advancement of Science. He co-organized 35 home and international conferences, among others the cycle of the European Conferences „Physics of Magnetism”, which he co-chaired since 1993.
