Opis:: This paper contributes to the growing body of literature exploring the ramifications of AI-driven technological singularity and its economic implications. The exploration unfolds in three key segments. First, it sheds light on the concepts of artificial general intelligence (AGI), AI superintelligence, and singularity itself. Subsequently, it discusses the AI alignment problem, addressing the potential outcomes of superintelligent AI on human civilisation. Further, Giddens’ structuration theory is used to highlight the prominent role of AI-based “authoritative resources” in determining the allocation of resources and ensuring distributive justice in a techno-utopian society. The paper also explores the idea of utopia and the “end of history” and concludes with the suggestion that achieving a technological utopia with superintelligent AI is a mechanism design problem.
Niniejszy artykuł stanowi wkład w rosnącą literaturę poświęconą konsekwencjom technologicznym osobliwości napędzanej przez sztuczną inteligencję (SI) i jej skutkom gospodarczym. Analiza skupia się na trzech kluczowych aspektach. Po pierwsze, uwagę poświęcono koncepcji ogólnej sztucznej inteligencji (AGI), superinteligencji AI i samej osobliwości. Następnie omówiono problem dostosowania SI, odnosząc się do potencjalnych skutków superinteligentnej SI dla ludzkiej cywilizacji. Wykorzystując teorię strukturacji Giddensa, podkreślono także znaczącą rolę „autorytatywnych zasobów” opartych na sztucznej inteligencji w określaniu alokacji zasobów i zapewnianiu sprawiedliwości dystrybucyjnej w społeczeństwie technoutopijnym. W artykule przeanalizowano również ideę utopii i „końca historii”, a we wnioskach zasugerowano, że osiągnięcie technologicznej utopii z superinteligentną sztuczną inteligencją stanowi problem projektowania mechanizmów.

Opis:: Subject and purpose of work: The paper focuses on the problems faced by farmers in obtaining and repaying loans from institutional and non-institutional sources. Materials and methods: The study was conducted in Haryana state, India. It was based on a field survey involving 600 farmers. Proportionate sampling technique was employed and pre-tested schedules were filled during vis-a-vis interviews. Results: The findings of the study highlight main problems faced by farmers in acquiring and repaying loans. They include: no loan without security, ambiguous terms and conditions, the time-consuming procedure of granting loans, not farmer friendly bank officials, and the request for bribes. In the case of non-institutional sources, main problems include: lack of security, deterioration of social status, and hesitation in mortgaging agricultural land. Furthermore, low price of agricultural produce, crop failure, and the high-interest rates charged by non-institutional sources were major constraints in the timely repayment of loan amounts. Conclusions: Several constraints existed in granting loans to farmers. Government should support and provide hassle free loans to farmers

Opis:: Introduction and aim. Any hospital’s outpatient department (OPD) is regarded as the storefront of the facility, and patient satisfaction is an important measure of healthcare quality. Hence, this cross-sectional study was conducted in different OPDs at a tertiary care center. Material and methods. Two hundred patients were recruited, and structured personal interviews were conducted with questions based on the Patient Satisfaction Questionnaire Short Form (PSQ-18). T-tests and analysis of variance (ANOVA) were used to compare satisfaction scores between variables. Results. Upon analysis, 86% of the patients rated their overall experience as either ‘very good’ or ‘good’. Interpersonal manners (mean score±SD; 4.60±0.55), communication (4.39±0.66), general satisfaction (4.03±0.79), and technical qualities (3.86±0.57) were the domains in which the patients were most satisfied, while time spent with the doctor (3.77±0.89), accessibility and convenience (3.77±0.67), and financial aspects (3.37±0.83) were the areas that lagged. Conclusion. Satisfaction scores were found to vary significantly with gender, age, waiting times, and the number of visits per day. Regular patient satisfaction surveys should be conducted in all hospitals for devising interventions to provide patients with the best possible care.

Opis:: Badanie ma na celu zmierzenie rentowności upraw przypraw, ich kanałów marketingowych oraz efektywności marketingowej i efektów rozpiętości cen. Zostało ono opracowane na podstawie badania terenowego przeprowadzonego wśród 320 rolników uprawiających przyprawy w stanie Hariana w Indiach w latach 2020–2021. Przedstawiono cele analityczne, skumulowany wskaźnik wzrostu, wskaźnik efektywności kosztowej oraz efektywność kanałów marketingowych i efekt rozpiętości cen. Wzrost powierzchni i produkcji roślin przyprawowych nie jest zbyt duży w porównaniu z opłacalnością upraw przypraw. Wskaźnik efektywności kosztowej pokazuje, że uprawy przypraw są dla rolników bardziej opłacalne niż uprawy tradycyjne. Jednak ze względu na wysokie koszty uprawy, zmienność cen i obawę przed nieurodzajami powierzchnia upraw przypraw jest znacznie mniejsza. Efekt rozpiętości cen jest bardzo duży w kanale I i II. Większość rolników przyjęła nieefektywny kanał marketingowy (niska cena dla producenta i wysoka cena dla konsumenta) ze względu na brak infrastruktury magazynowej i słabą kondycję finansową. Rząd odgrywa ważną rolę w ochronie praw producentów i konsumentów. Polityka rządu dotycząca marketingu upraw przypraw w stanie Hariana powinna zminimalizować rolę pośredników, aby rolnicy mogli uzyskać odpowiednią cenę za swoje przyprawy.
The study aims to measure the profitability of spice crops, their marketing channels, marketing efficiency, and price spread effects. The study was based on a field survey of 320 spice farmers of Haryana state in India carried out between 2020 and 2021. The authors presented analytical purposes, compound growth rate, cost–benefit ratio, marketing channels, marketing efficiency and price spread effect. The growth of area and production of spice crops is not very strong compared to the profitability of spice crops. Cost–benefit ratio shows that spice crops are more profitable than traditional crops for farmers. However, due to high cost of cultivation, volatile prices, and fear of crop failure, area under spices cultivation is very small. Price spread effect is very high in channel I and II. The majority of farmers adopted inefficient marketing channel (low price for producer and high price for consumer) due to lack of storage facility and weak financial health. The role of government is important for protecting the rights of producers as well as consumers. Mediators’ role should be minimized by government policy in the marketing of spice crops in Haryana so that farmers can charge the right price for their spice crops.

Opis:: Aim. Problems are inevitable in the subtleties of organizational communication, but it does not mean confronting them is uncontrollable. This paper aims to offer a conceptual structure for investigating contingency theory in Public Relations (PR) during an organizational crisis. The research investigates PR practitioners’ use of advocacy and accommodation in contingency theory to intervene in crisis communication. It also offers insights into the public’s emotional response and coping mechanisms during a crisis, as well as how understanding these emotions (such as anger, anxiety, fear, and grief, among others) could aid PR professionals in developing more effective crisis communication methods. Method. Empirical research was conducted on the basis of literature reviews by observing and analyzing the existing literature on contingency theory, crisis communication in organizations, and public emotions. Results. This conceptual paper proposes and empirically tests a few propositions. The implications for future studies are included in the paper. Findings promote the adopting a dual-continuum strategy that might assist public relations professionals in preferring superior crisis management strategies for obtaining desired organizational outcomes. Conclusion. The authors assert that PR professionals must move from embracing Grunig’s four models of excellence to contingency theory for communicating strategically with the public. The authors propose to adopt a dual-continuum approach that varies from advocacy to accommodation and might provide practical guidance to choose a better stance adopted by the organization towards the public during a crisis. The negative emotions of the public influenced by a crisis along with their emotional coping approaches are also discussed.

Opis:: Detection of the range of a target using laser range finders requires filtering of incoming data in real-time which can be achieved by a dedicated hardware to meet demanding time requirements. In this paper efficient filter structure which is the combination of constant false alarm rate (CFAR) and pipelined least mean square (LMS) adaptive filtering technique used to create solution for various adaptive filtering problems. Cell averaging (CA) CFAR and automatic censored cell averaging (ACCA) CFAR algorithm are fused separately with the adaptive filter in order to filter the incoming signal so that the detection of the of a target can be achieved through peak detection unit and accordingly range can be calculated. The design with CA-CFAR fused with PLMS filter is synthesized and implemented on a Xilinx Virtex4 FPGA with 32 MHz clock using Xilinx ISE software. Other design with ACCA-CFAR combined with PLMS filter is modeled and simulated in MATLAB simulink.

Opis:: This paper proposes a slotted patch antenna with wide bandwidth covering ISM frequency band (2.40-2.48 GHz) for implantable biotelemetry applications. A homogeneous skin phantom (HSP) model proves the usability of the proposed antenna in in-body environments. At a resonance frequency of 2.42 GHz, the design shows an S11 parameter of -35.56 dB, a percentage impedance bandwidth of 66.6% (2-4 GHz), and the maximum peak gain of -24.80 dBi. To validate the simulated results, the designed antenna was fabricated and measured, showing good compliance with the expected results. To ensure tissue safety, a specific absorption rate (SAR) is simulated for the proposed antenna which satisfies the requirements of IEEE standards, with a value of 87.75 W/kg for 10 g of tissue. The proposed antenna shows a telemetry range of 11 and 6.3 m at 7 kbps and 100 kbps data rates, respectively. The key features of the proposed antenna include the following: miniaturization, good S parameters, wide bandwidth, low SAR, good telemetry range, and high gain.

Opis:: In this paper the investigation of the FSW result characteristics on AA7075-T6 of the highest grade is carried out using different process parameters. A vertical milling machine with different FSW tool geometry is used to weld AA7075. When the tool rotational speed varies from 1200 and 1800 (rpm), different welding parameters are studied, the plunge depth of tool is between 0.14 and 0.20 mm, the table transverse speed range is between 20 and 50 (mm/min) and the tool shoulder diameter was 20 mm. The welding settings are optimized using the Taguchi approach. In this experimental investigation Taguchi Technique is utilized in this study to optimize three factorial and three level designs. The results show that when the rotating speed increases, the UTS of the welded joint increases, whereas the tensile strength of the welded joint decreases resulting to frictional heat created during the FSW process. Tensile strength decreases as feed increases and increases as rotational speed increases. For a 5 mm thick plate, tensile strength is optimal with a tool shoulder diameter of 20 mm, a rotational speed of 1600 rpm, feed rate of 30 mm/min and plunge depth. The shoulder diameter of 20 mm provides the maximum ultimate tensile strength when it is compared with all other tool shoulder diameter. The Al alloy AA7075-T6 plates, however, concurrently developed an equiaxial grain structure with a substantially smaller grain size and coarsened the precipitates.
