Smartphone Addiction and Subjective Withdrawal Effects: A Three-Day Experimental Study

Smartphones have arguably become a common necessity in modern society. While they can be used for many practical purposes, their many features increase the risk of overuse, a key element in behavioral addiction. The present study examined withdrawal-related scores on the Smartphone Withdrawal Scale, the Fear of Missing Out Scale, and the Positive and Negative Affect Schedule during a smartphone restriction period, lasting 72 h. In total, 127 participants were randomly assigned either to a condition without smartphone access or to a control condition. The scales were administered three times a day during the restriction period and smartphone addiction scores were assessed on Day 1. The results showed that participants with the highest scores on smartphone addiction in the restricted condition were significantly more negatively affected by the restriction (compared to those with lower scores). This appears to indicate that being restricted from using smartphones can generate significant withdrawal symptoms, especially for those at risk of smartphone addiction.

Системный подход к модели роста деревьев в лесу на основе уравнения Берталанффи

A universal, systematic approach has led to the identification of such indicators as the speed of the process of death and the development of forests. These forest indicators naturally depend on the type of trees in the forest, their state of health, as well as the degree of environmental impact. In forestry, there is a single generalized model of the growth and death of trees in the form of a growth model. The development model proposed by Von Bertalanffy is also known in relation to any growth indicator, mainly the diameter of the tree. The article is devoted to the issues of a systematic approach to the process of tree growth using the Bertalanffy growth model. The aim of the study was to find a relationship between the diameter and height of trees at which the target functional, compiled on the basis of the Bertalanffy model, reaches a maximum with some improvement. The improvement of the model is carried out as follows: a generalized indicator P, defined as the product of the diameter and height of the tree, is introduced for consideration. In general, this indicator determines the longitudinal section of trees and may be useful in forestry. On the other hand, a similar indicator, the product of D2 · H, is widely used in calculating biomass in trees, which indicates that the introduced indicator is sufficiently informative. Some restrictive conditions are assumed for the desired function of the relationship between the diameter and height of trees. To find the optimal ratio between these two indicators, a target function containing the desired function is formed on the basis of the Bertalanffy model. The problem of unconditional variational optimization is formulated and solved, as a result of which the optimal type of the desired function is calculated at which the target functional reaches a maximum.

Coefficient Problems of Quasi-Convex Mappings of Type B on the Unit Ball in Complex Banach Spaces

ABSTRACT In this paper, the sharp solutions of Fekete-Szegö problems are provided for class of quasi-convex mappings f 1 of type B and class of quasi-convex mappings f 2 of type B and order α defined on the unit ball in a complex Banach space, respectively, where x = 0 is a zero of order k + 1 of fi (x) − x (i = 1, 2). Compare with some recent works, our main theorems hold without additional restrictive conditions. Also, the proof of our main theorems are more simple than those given in the previous results.

Исследование влияния климатических факторов на скорость разложения лесной подстилки

The decomposition of the litter changes its indicators under the influence of climatic changes. Taking into account the impact of this process on the global carbon cycle, the decomposition process is a feedback affecting future climate change. The special role of the litter decomposition process in the overall carbon cycle on a regional and global scale determines the importance of studying the regularity of the influence of climatic parameters on the rate of decomposition of forest litter. Known approaches to solving this problem are based on a probabilistic analysis of the relationship between climatic factors. It is indicated that the task of determining the relationship between temperature and soil moisture when assessing their joint impact on the decomposition rate of forest litter can be formulated in a slightly different way. From the point of view of the ecology of the forest ecosystem, the following statement of the problem is no less interesting: under what relationship of these factors can the decomposition rate reach extreme values? The author proposes a representation of the problem being solved in the form of an extreme problem, taking into account some restrictive conditions imposed on the desired function of the relationship between temperature and soil moisture. The proposed new approach to solving the problem of the influence of climatic factors such as soil temperature and humidity, which consists of calculating the conditions leading to an extremum of the decomposition rate of forest litter, allows us to determine the function of the relationship between these factors and the point at which the decomposition rate reaches a peak. The solution to the problem allowed us to calculate the optimal type of the studied relationship, at which the rate of decomposition of the forest litter reaches an extreme. The results of the study can be used in modeling the processes of the influence of climatic factors on the overall carbon cycle of the forest ecosystem

Los principios cooperativos y las prácticas comunitarias de los socios de la cooperativa de cafeticultores Ñu-Xahoi

The objective of this investigation is to identify the cooperative principles, established in the General Law of Cooperative Societies of Mexico, that the members of the Ñu-Xahoi cooperative implement in their organizational processes; as well as deepen their community practices, linked to the social and solidarity economy, specifically, the social organization, community assemblies are resumed; as well as the tasks, in order to know the contribution they have had to the strengthening of the same cooperative. The importance of the work lies in making visible the cooperative experience of coffee producers from the Sierra Otomí-Tepehua of Hidalgo, whose members operate in a scenario of very restrictive socioeconomic and environmental conditions, where poverty and social backwardness predominate. The study method used for the research is ethnographic, which implies in-depth field work, based on participant observation, semi-structured interviews and directed interviews; as well as complementary instruments: photographs and maps. Among the first findings, it is found that the Ñu-Xahoi cooperative implements some cooperative principles established by law, such as freedom of association and voluntary withdrawal of members, democratic administration, promotion of ecological culture, etc. At the same time, it takes up elements of their community life, expressed in democratic, supportive and self-management practices that contribute to the strengthening of the organization itself, which means that the Ñu-Xahoi cooperative is part of a social and solidarity economy experience.

Adaptive calculation of river ecological flow considering the variable lifting volume under changing conditions

Abstract Ecological flow is a restrictive condition set for human water consumption in water resources management to protect river ecosystems. However, uncertainties in hydrological conditions, changes in regulatory capacity, and temporal-spatial differences bring difficulties to the implementation and supervision of ecological flows. By analyzing the relevant concept and connotation of ecological flow, it is concluded that the ecological flow regimes suitable for practical application should be a dynamic interval rather than a fixed value. Therefore, an improved ecological flow calculation method was proposed, which is to increase the feasible lifting volume for different ecological service objects based on the determined ecological baseflow. Taking two cross-sections of the Weihe River as an example, the ecological flow was calculated by comprehensively considering the factors of inflow, fish survival, landscape, and agricultural irrigation. The result shows the lifting volume occurred in the high flow season (April–June), and the maximum ecological flow of LJC and WJB cross-sections was 20.2 and 16.0 m3/s, respectively. Moreover, it is a generalized approach that can be extended to a more complicated river system, and the calculation results have reliability and adaptability in integrated water regulation.

Комплексная переработка минерального сырья: факторы готовности и сопротивления хозяйствующих субъектов

Ensuring the integrated processing of mineral raw materials remains a relevant topic of modern research due to its socio-economic, environmental and technological significance, as well as one of the key conditions for sustainable development of Russia, defined by the Strategy for the development of mineral resource base up to 2035. At the same time, the practical realization of this concept continues to be occasional and non-systemic. Under the new conditions of sanctions restrictions, the acute need for import substitution, taking into account the regional specifics of strategic mineral resources in the Arctic zone of the Russian Federation, it is necessary to change the paradigm of development of the resource and raw materials complex of Russia from extensive to intensive one and to shift the research context towards readiness of regional economic systems to such changes. Considering the accumulated scientific background, the article attempts to consolidate and systematize the research on the topic of integrated processing of mineral resources in relation to the factors that determine readiness and cause resistance to the practical implementation of the concept on the part of economic entities as key actors in this process. The scientific novelty of the study consists in the systematization of existing positions on the issue of transition to the implementation of the concept of integrated processing of mineral resources to develop a set of indicators as a tool for assessing the readiness and resistance of the regional economic system to the paradigm shift. The research method used is a review of publications on the topic of integrated processing of mineral resources. As a result of the study, 20 factors were identified and systematized into 5 groups. The obtained classification of factors can become the basis for further research of the question posed in this article, which will allow assessing the readiness for changes at the regional level, to identify obstacles that hinder their implementation, and to determine the directions of search for solutions to eliminating or levelling of the identified resistance factors.

Empirical analysis of network effects in nonlinear pricing data

Network effects, i.e., an agent's utility may depend on other agents' choices, appear in many contracting situations. Empirically assessing them faces two challenges: an endogeneity problem in contract choice and a reflection problem in network effects. This paper proposes a nonparametric approach to tackle both challenges by exploiting restriction conditions from both demand and supply sides. We illustrate our methodology in the yellow pages advertising industry. Using advertising purchases and nonlinear price schedules from seven directories in Toronto, we find positive network effects, which account for a substantial portion of the publisher's profit and businesses' surpluses. We finally conduct counterfactuals to assess the overall and distributional welfare effects of the nonlinear pricing scheme relative to an alternative linear pricing scheme with and without network effects.

Partial paleobathymetric restriction from the local North Sea Dome in the Viking Corridor during the Early-Middle Jurassic

The Early-Middle Jurassic (∼201–161.5 Ma) was characterized by major fluctuations in Earth's climate, tectonic activity, and large-scale magmatic events. There has been considerable focus on understanding the mechanisms that triggered the Early Jurassic Toarcian Oceanic Anoxic Event (TOAE; ∼183 Ma)—a warming episode associated with a perturbation of the carbon cycle. This was marked by a negative δ13C isotope excursion (CIE) and CO2 release from the Karoo-Ferrar Large Igneous Province (KF-LIP)—resulting in widespread organic carbon burial under strong euxinic marine conditions. Despite extensive study of the TOAE from the NW European epicontinental shelf, less focus has been placed on the influence of North Sea Dome (NSD) uplift (late Toarcian-early Aalenian) and eruption (Bajocian-Bathonian) on Jurassic paleoceanography. The NSD is a local feature commonly invoked as a driver of regional paleoclimatic conditions—a bathymetric barrier between warm Tethyan Ocean and cooler Boreal Sea waters. This study contributes new, high-resolution geochemical data derived from Viking Corridor (VC) cores and cuttings that fills a critical spatial and temporal gap in records spanning the Early-Middle Jurassic. Redox-sensitive trace elements (RSTEs; Mo/Al, U/Al, V/Al) as well as Cd*Mn and Cd/Mo ratios were used to reconstruct paleoceanographic and redox conditions. We track magmatic events and their implications using the relative enrichment of Hg, and attempt to decouple global versus regional/local volcanic systems with the enrichment factor values of mafic trace metals (MTM-EFs; Co, Cu, Ni, and Cr). Varying concentrations of RSTEs and a particulate shuttle mechanism during the Early-Middle Jurassic suggest that the VC had fluctuating paleoredox conditions, and that the NSD did not fully restrict the VC. We document a negative CIE as well as high Hg influxes during the TOAE—likely associated with KF-LIP eruptions (Early Jurassic). In addition, pulses of elevated Hg and MTM-EF values were observed during the Aalenian and Bajocian (Middle Jurassic) that were likely a result of NSD uplift and eruptions. The subaerial exposure of the NSD created progressively restricted conditions during the Aalenian-Bajocian, but the seaway between the VC and European epicontinental shelf remained open. Together, this work provides evidence that the NSD had a critical role in driving paleobathymetric and paleoceanographic conditions during the Early-Middle Jurassic. Furthermore, this study provides a geochemical insight into the interplay between δ13C isotope excursions, the KF-LIP, the NSD, and Hg-RSTE-MTM systems during an important transition in the Earth's biogeochemical history.

Shear resistance relaxation of granular materials under vibration and restricted deforming conditions

The phenomenon of vibration-induced shear resistance relaxation (ViSRR) refers to the loss of shear resistance in granular materials subjected to vibration, without an observable increase of excess pore pressure, under restricted deforming conditions. Essentially, ViSRR occurs when the total deformation of granular materials is unable to keep up with the plastic deformation induced by the vibration, given the restricted deforming conditions. In this study, ViSRR is investigated through a series of specially designed experiments together with theoretical simulation based on the extended shear transformation zone (STZ) model developed for granular materials. The results demonstrate that ViSRR takes place in granular materials under monotonic shearing when the vibration is superimposed, and the magnitude of shear resistance relaxation depends on the intensity of the vibration. The occurrence of ViSRR is subject to two fundamental prerequisites: superimposed vibration as the driving force for plastic deformation, and restricted total deformation that impedes a granular material's deformability to follow the development of plastic deformation. The simulation results obtained from the extended STZ model are in agreement with laboratory test results, indicating that the model is effective in describing the process of shear resistance relaxation and the accompanying volumetric strain during vibration.

Фізична активність підлітків в умовах соціального обмеження

A decrease in active movement is the cause of many diseases of modern man. The majority of schoolchildren in Ukraine (70.6% of boys and 83.0% of girls, 2016) did not follow recommendations for physical activity (PA). During the quarantine due to the COVID-19 pandemic, children’s PA was limited in many countries of the world. Increasing motor activity is one of the powerful means of preventing a number of cardiovascular diseases and metabolic disorders. Purpose - to determine the levels of PA of adolescents in the conditions of quarantine restrictions in connection with the COVID-19 pandemic; to establish the types of activities that ensure sufficient and low motor activity; to indicate ways of increasing it in adolescence. Materials and methods. The analysis of 138 questionnaires of teenagers aged 10-18 from spring 2020 to February 2022 was carried out: 68 girls and 70 boys. PA of adolescents was assessed using the International Adapted Physical Activity Questionnaire. All types of РA during the week (sports sections, active games, morning exercise, hiking, physical education classes) and the time spent on each type were taken into account. A total score of up to 7 points corresponded to low РA, from 7 to 8.9 to moderate, more than 9 to high РA. Results. 50.1% of teenagers had low FA, 22.4% middle, and 27.5% high. In the group of teenagers with low РA, only a third had motor games in the fresh air and morning exercises, 62% of them attended physical education classes and 18% - a sports section. Children with average РA in 35% of cases attended the section, 84% - physical education classes, and every second one did morning exercises and had active games. High РA consisted of a combination of sports (82%) and physical education lessons (87%), active games (66%) and morning exercises (68%). Almost all teenagers, regardless of the level of РA, had walks, but for every third person with low РA, their duration did not exceed 30 minutes. With average and high РA, the duration of walks in most people was more than 40 minutes. Conclusions. A more important task for educators, parents, doctors and the state as a whole is to increase the motivation of teenagers to physical culture and expand health and sports areas, their adaptation in periods of social restrictions. To achieve optimal РА, both the variety of types of activity and their duration are important. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the authors.

On the socles of isotype and balanced submodules

In this paper, we define a condition termed as cohesiveness on a submodule N of the socle of QTAG-module M, which is necessary for N to be the socle of an isotype submodule of M. It is proved here that for the countably generated submodule N, this condition is both necesaary and sufficient. We further define a restricted condition called as completely cohesiveness and shows that this condition is necessary and sufficient for a subsocle T of a QTAG-module which supports a balanced submodule of M.

Human SHQ1 variants R335C and A426V lead to severe ribosome biogenesis defects when expressed in yeast.

SHQ1 is an essential chaperone that binds the pseudouridine synthase dyskerin in the cytoplasm and escorts the enzyme to the nucleus, where dyskerin is assembled into small nucleolar RNPs (snoRNPs) of the H/ACA class. These particles carry out pseudouridine formation in ribosomal RNAs (rRNAs) and participate in maturation of rRNA precursors (pre-rRNAs). Variants of human SHQ1 have been linked to neurodevelopmental deficiencies; here we focused on two compound heterozygous mutations identified in a child showing a severe neurological disorder comprising cerebellar degeneration. To investigate the molecular defects caused by mutations R335C and A426V we used a conditional yeast strain that can be depleted of the endogenous Shq1 protein while constitutively expressing human SHQ1 (wild-type or variants). Although wild-type SHQ1 complemented the Shq1-depleted strain, cells expressing variant R335C could not support growth, and cells expressing variant A426V were temperature-sensitive. When shifted to restrictive conditions, yeast cells progressively lost H/ACA snoRNAs and accumulated unprocessed pre-rRNAs, which led to reduced production of ribosomes. Levels of Cbf5 (yeast homologue of dyskerin) were decreased in yeast cells expressing SHQ1 variants under restrictive conditions. Immunoprecipitation experiments revealed that interaction of Cbf5 with SHQ1 variants was weakened but not abolished, and yeast two-hybrid assays showed that mutation R335C is more deleterious than mutation A426V. Our data provide additional evidence for the critical role of SHQ1 in chaperoning the pseudouridine synthase dyskerin, and how its inadequate function has detrimental consequences on the production of H/ACA snoRNPs and ribosomes.

Ice breaking by low-velocity impact with a rigid sphere

Penetrator–ice plate impact subjected to dynamic loading constitutes many scientific applications for ice, such as controlling ice disasters by penetrating the ice cover and then entering underwater to explosive ice breaking on Earth, and life detection and resource development under water ice sheet on outer space planets. We present experimental results of brittle damage induced by a small spherical projectile impacting an ice plate with a thickness of 6–50 mm using a drop ball test device or a vertical gas gun. The corresponding impact velocities vary from 2 to 74 m/s. Crater parameters, residual velocity and energy absorption are investigated and assessed. The main fracture patterns and crater formation are captured by two high-speed cameras. A dynamic recrystallization phenomenon of polycrystalline ice is observed, and its formation mechanism is preliminarily analysed. The effects of the impact velocity, ice sample thickness, and restriction conditions on dynamic fracture processes and failure modes are systematically explored. These results improve our understanding of dynamic fracturing mechanism in ice engineering applications.

Using a fast hybrid pixel detector for dose-efficient diffraction imaging beam-sensitive organic molecular thin films

We discuss the benefits and showcase the applications of using a fast, hybrid-pixel detector (HPD) for 4D-STEM experiments and emphasize that in diffraction imaging the structure of molecular nano-crystallites in organic solar cell thin films with a dose-efficient modality 4D-scanning confocal electron diffraction (4D-SCED). With 4D-SCED, spot diffraction patterns form from an interaction area of a few nm while the electron beam rasters over the sample, resulting in high dose effectiveness yet highly demanding on the detector in frame speed, sensitivity, and single-pixel count rate. We compare the datasets acquired with 4D-SCED using a fast HPD with those using state-of-the-art complementary metal-oxide-semiconductor (CMOS) cameras to map the in-plane orientation of π-stacking nano-crystallites of small molecule DRCN5T in a blend of DRCN5T: PC71BM after solvent vapor annealing. The high-speed CMOS camera, using a scintillator optimized for low doses, showed impressive results for electron sensitivity and low noise. However, the limited speed restricted practical experimental conditions and caused unintended damage to small and weak nano-crystallites. The fast HPD, with a speed three orders of magnitude higher, allows a much higher probe current yet a lower total dose on the sample, and more scan points cover a large field of view in less time. A lot more faint diffraction signals that correspond to just a few electron events are detected. The improved performance of direct electron detectors opens more possibilities to enhance the characterization of beam-sensitive materials using 4D-STEM techniques.

The third category includes distribution functions for which entropy and its elasticity can be determined in tabular form. Basic information about the structure of the proposed calculator and examples of its application are provided. The method of determining the confidence interval of the point estimate of entropy is described. An example of using the calculator proposed in this message for planning an experiment related to entropy data analysis is given.

Critical import insurance as a tool to support entrepreneurs under sanctions

The article substantiates the relevance of state support for critical imports in modern conditions of political and economic restrictions. The current economic and political conditions of Russia’s development introduce significant business risks when concluding import contracts for importing critical goods and implementing additional supportive measures for importers of those goods that are duly recognized as critically important for the country’s economic development. As a result of the conducted research the conclusion about the lack of theoretical approaches to the understanding of critical imports and normative fixation of the sought concept has been made. Based on the analysis of regulatory legal acts of the Eurasian Economic Union and federal legislation of Russia, the system of support for critical imports at the supranational level and the level of the Russian Federation has been described. The commodity structure of the critical imported products lists has been analyzed. On the basis of them the conclusion about the large-scale dependence of the Russian Federation on foreign-made goods has been made. The necessity of state support of insurance of advance payments for imports of critical goods has been assessed and the algorithm of state support of advance payments insurance for critical goods imports described. The conclusion about the need for a comprehensive approach to support critical imports has been formulated and the one of the possible tools for its implementation proposed.

PHYSICAL ACTIVITY TREND DURING COVID-19 MOVEMENT RESTRICTION ORDER AMONG UiTM STUDENTS

The government of Malaysia has implemented a Movement Restriction Order (MCO) curfew on all citizens to prevent the Covid-19 pandemic from spreading. Studies have suggested that a long period of MCO will decrease overall weekly spending on energy for physical exercise in all age groups, ultimately promoting hypokinetic diseases. This study is interested in identifying the trend of physical activity behaviour changes during the Covid-19 MCO among university students. This study is also interested in comparing the mean score of physical activity level (inactive, minimum active, sufficient level) among samples. One hundred sixty-five (n=165) healthy samples age 19 to 23 years old currently enrolled as students from the Faculty of Sports Science and Recreation, University Teknologi Mara (FSR) answered the international physical activity questionnaire short form (IPAQ-SF) during the MCO period. Self-Reported Physical Activity Level has shown entirely contradicted from previous studies. 78.2% were at a sufficient level of physical activity; meanwhile, 20% were minimum, and 1.8% were reportedly inactive during the MCO period among FSR students. In addition, this study also found the differences of mean score in physical activity for sufficient level was (1438.78 SE=314.83), minimum active (-1268.65 SE=942.55), and inactive (-2707.43 SE=973.21). This study result showed that although, in restriction conditions in MCO, samples were still able to maintain their physical activity behaviour. The past physical activity practice can explain this phenomenon by these samples required throughout the lesson course, which has become a behaviour among these students.
