Opis:
This paper explores the phenomenon of marginal identities in Israel, focusing on the Ethiopian Jewish community as a representative case study. As a multicultural nation, Israel grapples with the intricacies of integrating diverse ethnic and religious groups into its social fabric. Ethiopian Jews, a small and unique group in the Israeli social landscape, face multifaceted challenges in their quest for acceptance. The research delves into the complexities of identity formation within the Ethiopian Jewish community, considering the interplay of their history of immigration to Israel, unique religious practices, and the process of integration into Israeli society. It is accompanied by comparisons to other aliyot, in particular Mizrahi Jews and post-Soviet Jews. By analyzing the power dynamics that define Ethiopian Israelis’ status within Israel’s imagined community, this paper seeks to unveil the reasons behind their marginalization in the country, in particular focusing on the construction of Israeli national discourse. Ultimately, this paper aims to deepen the understanding of marginal identities in Israel, using the example of Ethiopian Jews to shed light on the broader challenges faced by marginalized communities in diverse societies. The paper offers valuable insights for policymakers, social advocates, and scholars striving to promote inclusivity and social cohesion within multicultural nations.

Opis:
Nozick (1977) was a critique of the view of Austrian economics which rejected the notion of indifference in human action. This author claimed that this stance was incompatible with the notion of the supply of a good, and, also, with diminishing marginal utility, both of which were strongly supported by this praxeological school of thought. Block (1980) was an attempt to rescue the Austrian school from this brilliant intellectual challenge. Hoppe (2005; 2009) rejected Nozick’s challenge, and, also, Block’s (1980) response. Block (2009a) and Block and Barnett (2010), defended Block’s (1980) analysis of indifference. The latest contribution to this ongoing discussion is Wysocki (2021) who maintains that Hoppe was correct in his rejection of Nozick, while Block was not. The present paper is a rejoinder to Wysocki (2021).

Opis:
The aim of this article is to scrutinise the relationship between the moral attitude of an entrepreneur and their possibility to gain a competitive advantage. This declaration leads to the following question: Whether the everyday practice confirms or denies the economic usefulness ofthe postulate of corporate social responsibility. On the one hand, moral desertion is obviously profitable (also in an economic sense). Partners of the deserter, in most cases, are not able to avoid (unexpected and expansive) the consequences of this new attitude towards them. On the other hand, this strategy – in the long run – is unlikely to be profitable. The former victims adjust to their new circumstances and become ready to face the attack. Therefore corporate social responsibility, in the final calculation, should be taken as the only way to protect an active participant of the market against the temptation to neglect his obligation towards people, who can punish or reward him (as stakeholders or whistleblowers).

Opis:
This paper aims to find out how intense is the competition in Polish commercial banks loan market. Using Panzar – Rosse H-statistics and applying several estimation techniques (GLS, one-step GMM and two-step GMM) we find that this intensity is sensitive to the estimator applied. Upon analysis of results, one can conclude that competition evolves differently across years in Poland. In some years, competition was relatively high, as the H-statistics reached the level of 0.75, which is relatively close to perfect competition. In other years it gradually decreased reaching its bottom line in 2010, and took upward trend in 2011 and 2012. Generally, the values of our competitive environment measure indicate at monopolistic competition in Poland.

Opis:
The paper refines Lenk’s concept of improving the performance of the computed harmonic mean estimator (HME) in three directions. First, the adjusted HME is derived from an exact analytical identity. Second, Lenk’s assumption concerning the appropriate subset A of the parameter space is significantly weakened. Third, it is shown that, under certain restrictions imposed on A, a fundamental identity underlying the HME also holds for improper prior densities, which substantially extends applicability of the adjusted HME.

Opis:
The aim of the research was to study the floristic richness of balks, i.e. uncultivated strips separating fields, and to research the dependence of plant communities there on habitat conditions and adjacent crops. The share of segetal species in those communities was also analysed. In the western part of the Siedlce Plateau 70 balks among intensively cultivated fields were examined in 2016–2018. The balks divided fields with corn, winter cereals and spring cereal mixtures. The research was conducted with the Braun-Blanquet method, with 110 phytosociological relevés results used as study material. The flora specified this way was analysed in terms of biological structure, forms of life, persistence, historical and geographical spectrum, species rarity and presence of invasive species. In addition, the interdependence between the species richness of balks and habitat conditions as well as the type of neighbouring crops was studied. Habitat conditions were established with the Ellenberg indicator values, based on indicative species and taking into account light, temperature, moisture, soil reaction and nitrogen content. The development and floristic diversity of balk plant communities as ecotone areas were largely influenced by a proximity of arable fields and habitat conditions, especially by soil moisture and the amount of nitrogen. Balk flora consisted of vascular plants with 161 species, mainly apophytes. Those were mostly perennial species, hemikryptophytes. Among the most common field weeds from the class of Stellarietea mediae, 25 species were identified in balks. There were 26 rare and endangered species and 14 species having the status of invasive taxa.

Opis:
The presented study aimed at determining the influence of the increasing dose of new Z-ion zeolite substrate on the growth of maize (Zea mays L.) as species belonging to energy crops. In order to achieve the study aim, the pot experiment was carried out where the plants were grown on six series of media i.e.: on marginal soil (the control series I), on arable soil (the control series II) and on four mixtures of marginal soil with increasing Z-ion substrate addition (1%, 2%, 5%, 10 % v/v). The pot test was carried out in a phytotron with a 13/11 light/dark regime. After the end of the experiment, the mean values of the vegetative parameters (wet and dry biomass of roots and stems) characterizing the plant growth in particular media series were determined. The C:N ratio for maize stems was calculated as well. The obtained study results showed a favorable influence of Z-ion substrate additions on the vegetative growth of maize. Already a 1% (v/v) substrate addition to marginal soil increased the wet and dry stems biomass by 173–204%. At the same time, it turned out that in the sixth week of plant growth, a 5% substrate addition to the marginal soil enables to achieve the value of vegetation parameters at a level similar to that of the parameters characterizing the plant development on arable land. Thus, at an early stage of plant growth, a 5% substrate dose can be considered as one allowing a similar course of maize growing on marginal soil as in the case of arable soil. It is worth noting that at this substrate dose, the C:N ratio in maize stems reached the value of 13.05, at which the plant biomass is the substrate ensuring the fairly proper course of methane fermentation supplying fuel in the form of biogas.

Opis:
The paper presents a method of assessing the value of individual elements of the multigraph, i.e., the value of its vertices and arcs, considering the fuzziness of its parameters. The need to take into account the specificity of the existing types of vertices (including logical functions specified on them) and the possibility of multiple relationships between two neighbouring vertices make it necessary to use a multigraph. The assumed basis for the evaluation of the individual elements of the multigraph was their marginal value, which is the so-called contribution of a given element to the entire multigraph, assuming that the given element affects not only the adjacent elements directly related to it but in a way, perhaps indirect, every other element of the multigraph.

Opis:
Zjawisko kryzysu analizowane było wielokrotnie w literaturze ekonomicznej na podstawie różnych przesłanek. W niniejszym artykule uwaga do tematyki kryzysów skupiona została na podejściu systemowym. Zanalizowano prognozowanie lub antycypację stabilności kryzysów przy marginalnych zmianach parametrów modelu. Wprowadzono swoistą miarę stabilności systemu ze względu na różnorodność stanów w systemie i zmiany w modelu struktury. Wnioski z przeprowadzonych obliczeń potwierdzają zasadność takiego podejścia. Są one zbieżne z wykazywanymi w teoriach ekonomicznych ogólnymi prawidłowościami względem reakcji systemu na zmiany. Zaobserwowano analogie zachowania się systemów gospodarczych oraz finansowych w warunkach kryzysowych i postkryzysowych.
The phenomenon of the crisis was analyzed repeatedly in the economic literature based on different premises. In the article attention to the subject of crises is focused on systems approach. Forecasting or anticipating stability crises are analyzed with marginal changes in the model parameters. Introduced a specific measure of the stability of the system due to the diversity of states in the system and changes in the model structure. Conclusions from the calculations confirm the validity of this approach. They are consistent with those indicated in the economic theories general laws in reaction to changes in the system. Observed parallels the behavior of the system of economic and financial conditions of crisis and post crisis.

Introduction. One of the criteria of implant therapy success is marginal bone loss. The objective of the study was to assess the correlation between peri-implant marginal bone loss and implant-abutment connection systems used in the same patient, as well as other specific characteristics of implant treatment. The initial research hypothesis assumed that there was no difference in marginal bone loss around implants with different implant-abutment connection systems placed in the same patient. Materials and method. Marginal bone loss was assessed around implants with two different types of implant-abutment connection: with conical (Type I) and with internal hexagonal (Type II) in the same patient. The study included 28 patients aged 37–66 years. Results. Marginal bone loss around Type I implants was 0.112 mm/month before loading with prosthetic restorations, and 0.010 mm/month after loading, while for Type II implants it reached, respectively, 0.123 mm/month and 0.030 mm/month. Marginal bone loss after loading with prosthetic restorations was 11 times lower for Type I implants and 4 times lower for Type II implants. Evaluation of marginal bone loss in the studied patient groups was made on the basis of orthopantomographic radiographs. Conclusions. Implants with conical implant-abutment connection are significantly more favourable to osseointegration than those with internal hexagonal connection. As marginal bone loss is faster before loading implants with prosthetic restorations than after loading, it is advisable to consider early loading if the necessary clinical conditions are met.

Dry marginal agricultural land (DryMAL) potentially use as an alternative resource for crop production. DryMAL defined as land having low natural fertility due to its intrinsic properties and forming environmental factors. This study uses Sentinel-2A imagery to map the spatial extent, compare the result of the classification, and identify the change in DryMAL occupation. The area of study (461.9 km2) is part of Situbondo Regency and is located at the eastern part of East Java, Indonesia. Sentinel-2A image captured in dry-season of 2018 use for this study. Then, supervised image classification using a maximum likelihood algorithm use for image treatment and processing. Furthermore, 450 ground control points for training areas collected during the field surveys. Five bands use in the classification process. The maps produced from the classification process were then compared to the land-use map from the year 2000. The change in DryMAL occupation from 2000 to 2018 was calculated by comparing the classified and land-use map. Supervised classification yielded an overall accuracy of 95.8% and a kappa accuracy of 93.2%. The classification produced six (6) classes of land use: (1) forest, (2) pavement or built-up area, (3) irrigated paddy field, (4) non-irrigated rural area, (5) dry marginal land and (6) water body. Globally, during the last two decades, regional development led by the Regency occupied more DryMAL area for developing plantation. The effort reduces the amount of non-irrigated and converting to the plantation, pavement areas, and irrigated paddy-field.

Opis:
A review on the development of marginal oil fields in Nigeria has now become an important strategic issue if it is to remain amongst the top producers in the global market, and these fields are vast, available all over the Niger Delta. One of the factors that makes a field marginal is the size of its reserves. Stochastic estimation gives a certainty in terms of the possible number of outcomes within the range of input parameters. In this work, four (4) deviated wells and 3D seismic volume (362 inlines and 401 traces) were interpreted for the evaluation of the field. The petrophysical evaluations were interpreted using the Power Log software and the Seismic, Geographix and Petrel softwares. Stochastic reserve estimation was done using Monte Carlo sampling techniques and subjected to uncertainty quantification using the Crystal Ball software by varying distributions and measuring sensitivity impact on the overall reserves. The production profile was predicted based on some assumptions and history matching which result in the overall Expected Ultimate Recovery (EUR). The petrophysical analysis shows the reservoirs to be within the unconsolidated continental Benin Formation denoted as ‘Intra-Benin’ sands, an unconventional reservoir as supposed the normal reservoir rocks within the Agbada Formation. This indicated high porosity (0.28), water resistivity (7 Ω∙m), and water saturation and also inferred Heavy Oil (low API). Nine hydrocarbon sands were identified but only three (B1, D and E), representing shallow, mid and deep reservoirs were further evaluated. 1P and 2P reserve estimates were 4.8 MMBO and 5.7 MMBO for B1; 15.2 MMMscf and 16.4 MMMscf for D; 8.4 MMMscf and 8.8 MMMscf for E respectively. The Monte Carlo simulation of 1,000,000 trials with mainly triangular distribution assumption generated P10, P50, P90 were 6.5 MMBO, 5.6 MMBO and 4.4 MMBO for B1; 17.5 MMMscf, 13.7 MMMscf and 10.8 MMMscf for D; 10.4 MMMscf, 8 MMMscf and 6.1 MMMscf for E respectively. The sensitivity impact of the input parameters were estimated and ranked, and the coefficient of variability ranges within 15% to 20% for the reservoirs indicating that there is a very low level uncertainty of reserve estimation around the P10, P50 and P90 percentiles which could be positive for investment decisions. ‘OWA’ marginal field reflects a typical low reserve (EUR) category found within the Niger Delta basin.
