Published: June 2024

The development of offshore fields in the Northern Caspian Sea is a rare and unique project for the Russian Federation. The Yu. Korchagin field is the first offshore hydrocarbon development project in the Russian Federation. During the development, operation, production, and transportation of carbon-hydrogen raw materials from the field, some problems were identified, such as premature water breakthrough, gas breakthrough, the presence of a gas cap, an inappropriate type of completion, failure to meet targets and requirements, which may lead to the failure to achieve the desired oil recovery coefficient. For PJSC Lukoil, it is necessary to conduct a more thorough analysis, identify the reasons for solving problems, and make decisions on liquidation. One of the main problems of well construction in the fields of the Northern Caspian Sea is to ensure the quality of casing cementing, especially in areas of abnormally high reservoir pressure. The increase in drilling depths and the complication of geological conditions make it difficult to solve this problem. A special place in this issue is occupied by the problem of the appearance of inter-column pressures. The primary technological task and problem of LUKOIL-Nizhnevolzhskneft, LLC is the search for new technologies and chemical compounds for the successful liquidation of inter-column pressures in wells and the implementation of such operations in the shortest possible time. The contractor has implemented two effective methods to solve this problem. The article discusses methods for reducing inter-column pressure and the effectiveness of their application at the North Caspian field, as well as planned and ongoing measures to minimize the risk of intercolonial flows during well construction

Macroeconomic Expectations and Cognitive Noise
Authors:   Federal Reserve Bank of San Francisco, Sung Yeji
Published: June 2024

This paper examines forecast biases through cognitive noise, moving beyond the conventional view that frictions emerge solely from using external data. By extending Sims’s (2003) imperfect attention model to include imperfect memory, I propose a framework where cognitive constraints impact both external and internal information use. This innovation reveals horizon-dependent forecast sensitivity: short-term forecasts adjust sluggishly while long-term forecasts may overreact. I explore the macroeconomic impact of this behavior, showing how long-term expectations, heavily influenced by current economic conditions, heighten inflation volatility. Moreover, structural estimation indicates that neglecting imperfect memory critically underestimates the informational challenges forecasters encounter.

Ridiculing Astrologer Origen’s Sources and His Legacy
Authors: PERENDY László
Published: June 2024

This article examines the early Christian critique of astrology, focusing on its perceived conflict with the concept of free will. Key figures such as Origen, Tatian, and Bardesanes are highlighted for their contributions to this discourse. Origen’s works, including his homilies and commentaries on the Book of Genesis, notably oppose the deterministic implications of astrology by asserting human free will and divine omnipotence. Tatian’s writings, particularly his “Oratio ad Graecos,” condemn astrology as a demonic invention that undermines Christian doctrines. Bardesanes, who is well-informed in astrology, differentiates between cosmic influences and moral decisions, arguing that ethical behavior is not determined by the stars. The article also explores the theological and philosophical foundations of these arguments, tracing influences from earlier thinkers like Philo of Alexandria and Carneades. Overall, the text provides a comprehensive analysis of how early Christian writers engaged with and refuted astrological beliefs.

Mental Disorders in Anglo-Saxon Hagiographies
Authors: ZÁVOTI Zsuzsa
Published: June 2024

This article examines the representation of mental disorders in Anglo-Saxon hagiographies, analyzing perceptions, symptoms, cultural contexts, and narrative purposes. Anglo-Saxon views on the mind and soul, influenced by both vernacular and classical traditions, shape understandings of madness. Old English terminology for madness reflects diverse cultural influences, ranging from naturalistic-organic to supernatural etiologies. Analysis of the hagiographies show that there was a tendency to depict demon possession as madness, which could partly be attributed to the Anglo-Saxon way of perceiving the soul and mind, partly to the narrative purpose, and partly to the influential sources.

A Hungarian Franciscan Preaching in Romanian. The Romanian Sermons of Olti István, OFM in Hungarian Transliteration
Authors: NÓDA Mózes
Published: June 2024

Franciscans carried out an important pastoral ministry in the Diocese of Alba Iulia, which included Romanian-speaking communities. A particular example of this ministry is the decades-long preaching of István Olti, OFM, a Hungarian friar, to Romanian believers, in the first half of the 19th century. This essay discusses his unpublished Romanian sermons given in Grădiștea de Munte, Sibișel, Sebeșel and Rodna Veche, preserved in the Franciscan Archives in Cluj. The sermons, entirely inspired by the Bible, are interesting not only as witnesses of the Franciscan ministry to Romanian-speaking communities, but also as examples of religious texts in Romanian, written with Latin characters, a phonetic transcription using Hungarian letters and digraphs, in a (trans)formative period of the Romanian language, when writing and printing used Cyrillic characters.

Extensive research indicates that enhancing employee satisfaction and motivation leads to improved organizational performance. Given the crucial role public managers play in delivering quality public services, ensuring their satisfaction becomes paramount. This study, based on survey data from approximately half a million U.S. federal government employees, explores the factors influencing public managers’ job satisfaction and investigates whether managerial positions moderate these effects.
The findings reveal that overall job satisfaction is positively impacted by satisfaction with both intrinsic and extrinsic job aspects, irrespective of managerial status. However, the influence of intrinsic and extrinsic factors on overall job satisfaction undergoes significant changes when a public employee assumes a managerial position.

Although multiple studies focused on the effects that the Covid-19 pandemic had on students and the strategies adopted for dealing with the effects, few authors looked at what was on the other side of the educational process – teachers. The pandemic had the same influence on teachers as it had on any other social or professional group, leading to increased levels of stress, insomnia, anxiety, uncertainty, fatigue or burnout. However, even faced with these issues, educators had to continue their activity and adapt at a moment’s notice to a different paradigm of doing their job and shift from on-site to online teaching.
The current qualitative research looks at the multiple effects the public health crisis had on professors in terms of personal and professional life. The paper reviews the measures adopted by educators to adapt to online education, ranging from updates of the course Syllabuses, educational contents, new evaluation methods, video services, and educational platforms used, to communicate and motivate students or the positive and negative facets of e-learning. The interview guide also includes elements related to the future of teaching PA in the post Covid-19 era, the sustainability of online education, and the prospects of returning to the previous paradigm.
The empirical research was conducted using semi-structured interviews, the respondents being educators from the Public Administration programs of Babes-Bolyai University of Cluj-Napoca, Romania. Male and female respondents (N=19) ranged from PhD students at the beginning of their teaching activity to full professors with more than two decades of experience. The lessons derived from the Covid-19 pandemic are useful for understanding how universities as a whole and professors in particular deal with the uncertainties and turbulence generated by crises, focusing on systemic and individual resilience.

This article aims to investigate the jurisprudence of the Constitutional Court regarding the public administration reform in Romania. We take into consideration the motivation of the public authorities involved in the law-making process, as well as the interpretation of the judges of the Constitutional Court concerning the legislative steps regarding the adoption of an Administrative Code, decentralization, the transfer of competences, the status of civil servants, and finally the legal regime of the newly established or reorganized institutions/authorities.
The study also evaluates the steps to reform the public administration concerning the observance of the principles of constitutional loyalty, the separation of powers, the supremacy of the Constitution, and the role of the Parliament.

The livelihood of ethnic minority households in Vietnam is mainly in the fields of agriculture and forestry. The percentage of ethnic minorities who have jobs in industry, construction, and services is still limited. Moreover, due to harsh climate conditions, limited resources, poor market access, low education level, lack of investment capital for production, and inadequate policies, job opportunities in the off-farm and non-farm activities are very limited among ethnic minority areas. This paper assessed the contribution of livelihood diversification activities to poverty reduction of ethnic minority households in Son La Province of Vietnam. The analysis was based on the data using three stages sampling procedure of 240 ethnic minority households in Son La Province. The finding showed that the livelihood diversification activities had positively significant contribution to poverty reduction of ethnic minority households in Son La Province. In addition, the factors positively affecting the livelihood choices of ethnic minority households in Son La Province of Vietnam are education level, labor size, access to credit, membership of associations, support policies, vocational training, and district. Thus, improving ethnic minority householder’s knowledge through formal educational and training, expanding availability of accessible infrastructure, and enhancing participation of social/political associations were recommended as possible policy interventions to diversify livelihood activities so as to mitigate the level of poverty in the study area.
Dano moral pela perda do tempo útil nas relações de consumo
Authors: Rodrigues Pávola Marcela Martins , Oliveira Rejane da Costa de , Dutka Joel
Published: June 2024

Este trabalho apresenta a análise do tratamento jurisprudencial em Santa Catarina sobre o fator “tempo” como bem indenizável nas relações de consumo a partir das teorias do desvio produtivo e punitive damages. A teoria do desvio produtivo considera que a completa reparação dos danos morais nesses casos requer o reconhecimento, valoração e a indenização do tempo desperdiçado pelo consumidor na tentativa de resolução dos conflitos. Já as punitive damages, ou condenações punitivas, servem como forma de punição ao fornecedor pelo dano causado ao consumidor, não necessariamente a partir do tempo desperdiçado, mas pelo objetivo de fazer cessar os abusos praticados. O principal objetivo com a pesquisa foi analisar as variáveis consideradas para indenização pelo tempo desperdiçado nas relações de consumo. A metodologia do trabalho é predominantemente qualitativa, com abordagem dedutiva, e as principais ferramentas metodológicas foram a pesquisa bibliográfica, a análise de documentos e a análise de discurso. As fontes de pesquisa foram livros, artigos e julgados do Tribunal de Justiça de Santa Catarina, a partir dos filtros “desvio produtivo” e “punitive damages”. Além das divergências na fundamentação das decisões, verificou-se que os critérios considerados na fixação da indenização não são claros, o que prejudica a análise sobre o impacto de cada teoria no montante indenizatório.
obsolescência programada como prática abusiva nas relações de consumo
Authors: Streck Maria Eduarda Lopes Pereira , Gehelen Maristela Heinen
Published: June 2024

O presente estudo visa abordar a obsolescência programada e seus impactos nas relações de consumo, apontando suas qualificações, origem e os danos decorrentes de tal prática. Constata-se que a evolução da sociedade fez surgir o hiperconsumo, que junto às inovações tecnológicas, contribuíram para uma menor vida útil dos produtos, principalmente quando há a ingerência do fornecedor. O objetivo do presente trabalho é demonstrar como a obsolescência programada é uma prática abusiva frente à relação de consumo, visto a clara vulnerabilidade do consumidor diante do fornecedor. E, portanto, conclui-se a necessidade da interferência estatal para reequilibrar a relação de consumo e obstar que o fornecedor se valha da sua condição e atue de forma arbitrária. Metodologicamente a pesquisa classifica-se como dedutiva, descritiva e bibliográfica, com técnica de revisão bibliográfica e jurisprudencial.
Complementary description of the female of Typhlodromus (Anthoseius) xini Wu (Acari: Phytoseiidae) with the first description of its male from Sri Lanka

Published: June 2024

Typhlodromus (Anthoseius) xini Wu is reported for the first time in Sri Lanka. Its original description is not very detailed, being based on simple drawings and an absence of diagnostic characters that include chelicera dentition and leg chaetotaxy. Therefore, a complementary description and new illustrations of this species are provided, based on specimens from both sexes collected from Cocos nucifera L. (Arecaceae) infested by spiralling whiteflies in Puttalam District, North Western Province, Sri Lanka. In addition, this is the first discovery and the first description of the unknown male. We also provide a brief comparison between T. (A.) xini and some other species of the subgenus such as T. (A.) diumbokus Schicha and Corpuz-Raros, T. (A.) foraminosus, T. (A.) hartlandrowei Evans, T. (A.) neohartlandrowei Zannou, Moraes and Oliveira, and T. (A.) transvaalensis (Nesbitt). All of these species are similar to each other based on the nature of their dorsal and ventral aspects, chelicera dentition, and spermatheca morphology. Most importantly, ventral seta JV3 is absent in all of these species. In our opinion, it is apparent that all of the aforementioned species share a common ancestor. Therefore, additional molecular analysis, in combination with the use of morphological characters, would help to confirm the taxonomic relationship and evolutionary history of these species. Finally, we also proposed T. (A.) gosabaensis Kar and Karmakar as a new junior synonymy of T. (A.) xini based on the examination of its holotype.

OBJECTIVE

To establish the pharmacokinetics of the cyclin-dependent kinase-9 inhibitor flavopiridol in equine middle carpal joints, using an extended-release poly lactic-co-glycolic acid (PLGA) microparticle formulation.

ANIMALS

4 healthy horses without evidence of forelimb lameness.

METHODS

A 6-week longitudinal pharmacokinetic study was conducted in 2 phases (6 weeks each) in 4 healthy horses. The PLGA microparticles containing 122 μg flavopiridol in 3 mL saline were administered by intra-articular injection into 1 middle carpal joint, with empty PLGA microparticles injected into the contralateral joint as a control. Synovial fluid and plasma were collected at time points out to 6 weeks, and drug concentrations in synovial fluid and plasma were determined using validated protocols. Synovial fluid total protein and total nucleated cell count and differential, CBC, serum biochemistry, and lameness exams were performed at each of the time points.

RESULTS

Synovial fluid flavopiridol averaged 19 nM at week 1, gradually reduced to 1.4 nM by 4 weeks, and was generally below the detection limit at 5 and 6 weeks. There was no detectable flavopiridol in the plasma samples, and no adverse effects were observed at any time point.

CLINICAL RELEVANCE

Intra-articular injection of PLGA microparticle-encapsulated flavopiridol was well tolerated in horses, with detectable levels of flavopiridol in the synovial fluid out to 4 weeks with negligible systemic exposure. Flavopiridol is a cyclin-dependent kinase-9 inhibitor with potent anti-inflammatory and analgesic activity. The extended-release microparticle formulation promotes intra-articular retention of the drug and it may be an alternative to other intra-articular medications for treatment of equine joint disease.
