Direct vs. staged TAVI in the acute management of decompensated severe aortic stenosis

Abstract Funding Acknowledgements None. Background Transcatheter aortic valve implantation (TAVI) has emerged as a preferred treatment for severe aortic stenosis across a spectrum of surgical risks, potentially diminishing the role of balloon aortic valvuloplasty (BAV) as a transient solution or a bridge to definitive intervention. With advancements in TAVI technology and expertise, patients even in unstable conditions are increasingly receiving direct, definitive TAVI, avoiding the risks associated with staged, multiple procedures. Aims The study set out to assess whether immediate TAVI is safer and more effective than BAV followed by elective aortic valve replacement (AVR) in acute severe aortic stenosis. Methods Conducted as a retrospective analysis at a single center, this study encompassed a cohort of consecutive patients who received either urgent or emergency BAV, as bridge to AVR, or TAVI to manage decompensated severe aortic stenosis from May 2012 to May 2023. The primary outcomes were mortality rates at both 30 days and one year following the procedures. Results In this cohort, 258 cases of urgent or emergent percutaneous aortic valvuloplasty were evaluated. BAV was performed in 47 patients, whereas 211 received direct TAVI. A significantly higher proportion of the BAV group (36%) was treated due to cardiogenic shock as the primary indication, compared with just 11% in the TAVI group (p< 0.001). Demographic parameters and comorbid condition profiles were equivalently balanced across both groups. The median age was 81 years (interquartile range: 74-85, p= 0.40), and males constituted 56% of the patient population (p= 0.72). Most patients (65%) presented with left ventricular systolic dysfunction, and nearly half (49%) were diagnosed with obstructive coronary artery disease. The reduction in peak aortic valve gradient was significantly more pronounced in the TAVI group (-56±25 mmHg) compared to the BAV group (-27±19 mmHg, p< 0.001). TAVI recipients also had a higher incidence of VARC-2 minor and major bleeding events (26% versus. 6% for BAV, p<0.001), and a greater occurrence of advanced atrioventricular block necessitating temporary pacing (19% vs. 9% for BAV, p= 0.02). Thirty-day survival rates favored the TAVI group (93%) over BAV (86%). This trend persisted at the one-year mark, with survival rates of 84% for TAVI and 70% for BAV. Furthermore, the one-year hazard ratio for mortality among patients undergoing BAV was 2.01 (95% confidence interval: 1.34–3.01, p< 0.001). Conclusion The data from this retrospective analysis indicate that for patients with decompensated severe aortic stenosis, immediate TAVI may confer a mortality benefit over BAV followed by elective procedures. Despite a higher rate of procedural complications, the direct TAVI approach was associated with better survival rates at both 30 days and one year. These outcomes suggest a potential reevaluation of treatment strategies in acute settings may be warranted.

Wind Shear Model Considering Atmospheric Stability to Improve Accuracy of Wind Resource Assessment

An accurate wind shear model is an important prerequisite in extrapolating the wind resource from lower heights to the increasing hub height of wind turbines. Based on the 1-year dataset (collected in 2014) consisting of 15-minute intervals collected at heights of 2, 10, 50, 100, and 150 m on an anemometer tower in northern China, the present study focuses on the time-varying relationship between the wind shear coefficient (WSC) and atmospheric stability and proposes a wind shear model considering atmospheric stability. Through the relationship between Monin–Obukhov (M-O) length and gradient Richardson number, the M-O length is directly calculated by wind data, and the WSC is calculated by combining the Panofsky and Dutton (PD) models, which enhances the engineering practicability of the model. Then, the performance of the model is quantified and compared with two alternative methods: the use of annual average WSC and the use of stability change WSC extrapolation. The analysis demonstrates that the proposed model outperforms the other approaches in terms of normal root mean square error (NRMSE) and normal bias (NB). More specifically, this method reduces the NRMSE and NB by 24–29% and 76–95%, respectively. Meanwhile, it reaches the highest extrapolation accuracy under unstable and stable atmospheric conditions. The results are verified using the Weibull distribution.

Transformation of integrated formations in industry

Modern realities are such that the priority in the activities of any company is its efficiency, and it does not matter in what area or sector of the economy it operates. Making a profit is the main goal for managers, and even more so for company owners, and any opportunity to minimize costs and thereby increase their assets will be used by business. One such way for large corporations to reduce costs is to move from the status of a holding structure to that of a group of companies. If necessary, companies that have chosen such an organizational and legal form can quickly respond to changes in the external environment and focus the necessary company resources in one direction to promptly decide on a strategic task and its immediate implementation. Such associations manifest themselves most clearly in extreme conditions, and where other companies go into the red, they show positive dynamics in revenue growth. The article presents the results of the author’s research on the above topic. For analysis, some aspects of the organizational activities of holding structures and groups of companies were selected, such as legal issues, the status of companies, the possibility of bankruptcy and mutual liability of organizations within the company, consolidation and redistribution of profits, finances, resources, means of production and logistics; image and business reputation; control system; risks; relationships with partners and employees; pricing policy and taxation. Groups of companies operating in agro-industrial complexes and agriculture have proven to be more mobile and adapt faster in unstable economic conditions due to the decentralization of legally free company members.

Art on the chain? On the possibilities of new media art preservation on the Web3

ABSTRACT The absence of clear protocols in the conservation of new media art has led to a situation of extreme precariousness of digital artworks. The irruption of blockchain culture and NFTs seems to offer an opportunity to overcome this situation. This paper aims to clarify whether or not the structure of data and metadata associated with transactions in the blockchain solves the challenging obsolescent and unstable condition of new media art. The disturbing reality is that the so-called ‘cryptoart’ is not always stored and encapsulated on the blockchain itself. In a high number of cases, assets just point to artworks living outside, stored on off-chain servers or platforms. This paper analyzes the possibilities for the preservation of art hosted on the chain. Despite some limitations, this method is understood as the more coherent and robust for long-term life and availability of digital art associated with Web3 technology.

Spatio-temporal Analysis of the factors affecting NOx concentration during the evaluation cycle of high pollution episodes in Tehran metropolitan

Tehran, the capital of Iran, experiences high levels of pollution, particularly during the cold seasons. Recent studies have shown an increase in the concentration of nitrogen compounds in Tehran. However, the role of advection, deposition, vertical diffusion processes and chemical conversion of NOx in this region requires further investigation. In this study, The Weather Research and Forecasting model with Chemistry (WRF-Chem) was employed to numerically simulate each of these processes during a severe pollution episode in winter from November 28, 2021, to December 8, 2021. During this high pollution episode, the weather conditions were calm, and based on the Air Quality Index (AQI), the air quality was unhealthy for sensitive groups. The presence of a ridge at the 500 hPa level, the placement of a low-level high-pressure cell over the region, and consequently, atmospheric subsidence and low wind speed create favorable conditions for severe pollution events in Tehran. Additionally, temperature inversion during the night and a decrease in the boundary layer height contribute to increased surface NOx concentration during this period. When comparing different processes influencing NOx concentrations, it has been observed that advection has the most significant impact, while dry deposition and chemical conversion have the least effect. On stable days advection increases NOx concentration in central and northeast of Tehran urban area during daytime. The maximum vertical diffusion is observed in the southern and western regions, corresponding to the emission pattern of NO and NO2. The examination of the vertical profile of advection and vertical diffusion shows that vertical diffusion dominates near the surface layer, while advection dominates at higher altitudes in terms of NOx concentration changes. Under unstable conditions (Dec-02), with arrival of the cold front and the influence of convective clouds, the impact of convective transport becomes more pronounced in reducing NOx concentrations in the southern and central regions of Tehran urban area. The highest NOx deposition is observed in the early morning in the southern and southwestern suburban areas of Tehran, correlating with wind direction variations, NOx concentration, and vegetation coverage. The results indicate that nearly 98% of the total NOy deposition (dry and wet deposition of NO, NO2, HNO3, and NO3) in Tehran's urban and suburban area is attributed to dry deposition of NO2.

ДИФЕРЕНЦІАЛЬНО-ПСИХОЛОГІЧНІ ОСОБЛИВОСТІ СТАВЛЕННЯ ДО ПРАЦІ В УМОВАХ ВОЄННОГО СТАНУ

The study aims to investigate the impact of a state of war on employees’ attitudes towards their work and identify the differential psychological features influencing this process. The article’s goal is to develop justified management strategies aimed at mitigating the effects of the state of war on the employees’ mental well-being and supporting their positive work attitudes. The research methodology included anonymous surveys of personnel (1667 respondents), analysis of results using One-Way ANOVA, and multinomial regression analysis. The obtained results emphasize the significance of traits such as friendliness, emotional stability, and openness to new experiences in shaping a positive work attitude during a state of war. The identified correlations between these traits and the impact of the state of war underscore the need for the development of social competencies among the employees. Social factors, such as satisfaction with the team atmosphere, relationships with colleagues and family, and the influence of office conditions and domestic life, also proved essential for shaping work attitudes in a state of war. A supportive work environment and colleague assistance can be crucial for maintaining a positive psychological climate and work efficiency. In the context of managerial recommendations, the research emphasizes the importance of developing employees’ personal qualities, particularly friendliness, and formulating strategies to support social and psychological well-being in the workplace. Managerial interventions should primarily target female employees and those who are unmarried and hold non-managerial positions in the organization. The article makes a significant contribution to understanding the mechanisms of employee adaptation to stressful conditions and proposes specific approaches to managing psychosocial climate in organizations during crisis situations. The findings can be valuable for managers and HR departments seeking to ensure effective personnel management in unstable conditions and enhance overall workplace comfort and motivation. Key words: state of war, differential psychological features, Big Five, five-factor model of personality, attitudes toward work, motivation, demotivation.

Autochthonous grape varieties in the Lower Don Region

This article describes modifi cation changes in the phenotypic traits of grape varieties, including the number of normally developed shoots and infl orescences, the average bunch weight, and grape yield under the infl uence of unstable weather conditions. The research was carried out in the moderate continental climate of the Lower Don region in the period from 2013 to 2022. The average annual air temperature ranged from +10.2 to +11.6 °C, with the climatic norm being +10.4 °C. In the period of active vegetation (May–September), the temperature ranged from +21.2 to +22.7 °C, with the norm being 18.1 °C. The maximum temperature ranged from +37.2 to +40.0 °C, with the norm being +40.0 °C. In winter, during the plant dormancy period (December–February), the average air temperature varied from 0.6 to minus 2.6 °С, with the norm being about minus 2.4 °С. The annual precipitation varied from 292 to 693 mm, with the norm being 548 mm. During the vegetation period of grapes, atmospheric precipitation by the years of observation varied from 99 to 359 mm, with the norm being 177 mm. The aim was to establish the limits of modifi cation variability of phenotypic traits under the infl uence of the unstable moderate continental climate of the Lower Don Region. The research objects were autochthonous grape varieties, including ‘Varyushkin’, ‘Krasnostop’ ‘Zolotovsky’, ‘Kumshatsky Belyi’, ‘Plechistik’, ‘Sibirkovy’, and ‘Tsimlyansky Chernyi’. The reaction norm and modifi cation changes of the phenotypic traits of grape plants under the infl uence of natural conditions in their habitats were studied. The autochthonous grape varieties in contrasting weather conditions exhibited individual and varietal specifi city in terms of reaction norm and adaptability. According to the variability of phenotypic traits and adaptive potential, the varieties were ranked in the following descending order: ‘Plechistik’, ‘Krasnostop Zolotovsky’, ‘Varyushkin’, ‘Kumshatsky Belyi’, ‘Sibirkovy’, and ‘Tsimlyansky Chernyi’. The genotypes ‘Plechistik’, ‘Krasnostop Zolotovsky’, ‘Varyushkin’, and ‘Kumshatsky Belyi’ with their high adaptive potential for formation of stable vine plantations are recommended for developing stable grape plantations in the conditions of the Lower Don region.

Issues of gas film stability with performance characteristics in u-ECDM: A review of existing approaches and preliminary investigation on proposed stable & sustainable approach

Micro-featured devices (made of glass and its composites) are becoming increasingly necessary for Micro Electro-Mechanical Systems (MEMS) and healthcare devices with the emergence of technology. Due to limitations of existing methods, Micro Electro Chemical Discharge Machining (μ-ECDM) is an evolving technique for difficult to micro machine materials like glass. However, improper flushing and unstable electrolytic conditions in the processing zone percolates the efficacy, accuracy, and repeatability of μ-ECDM. Consequently, deteriorating the sustainability and industrial feasibility of this process. To cope up with these problems, various approaches like ultrasonic assistance, rotary mode, magneto hydrodynamic are integrated and investigated with μ-ECDM in the literature. Although these approaches achieved the intended objectives but do not assure the stability and sustainability of the process, which are essential for industrial feasibility in the present scenario. The present review has stressed upon the effects of existing approaches on gas film formation, discharge characteristics and performance outcomes. Systematic review methodology indicated the extensive usage of ultrasonic vibrations in μ-ECDM and, the studies on the stability/sustainability of μ-ECDM process are neglected. According to literature and preliminary investigation, problems pertaining to the rising electrolyte temperature and heterogeneous electrolyte concentration are the attributed reasons, which affects the stability as well as sustainability. Therefore, the present review proposed an innovative approach to achieve the stability and sustainability of μ-ECDM process by controlling the electrolytic conditions (termed as controlled-ECDM). A preliminary experimental investigation witnessed the enhancement of process performance and quality characteristics in controlled-ECDM.

STRATEGIC MANAGEMENT AND SUSTAINABLE ECONOMIC DEVELOPMENT

The article is devoted to the search for conceptual solutions to the problem of ensuring sustainable economic growth in the new unstable economic conditions. This topic remains extremely relevant in the modern world, where various challenges are faced, such as climate change, resource depletion, population growth, increased social inequality and other problems. The authors explore the evolution of the concept of sustainable development, highlighting various essential aspects of understanding the category of sustainability. In different time periods, climate change and environmental challenges, social justice and efficiency, global cooperation and risk management, digitalization and technological innovation have consistently been at the center of the problem of sustainable development. As a result, strategies to reduce the negative impact on the environment and adapt to climate change have been replaced by strategies of green technologies, which, in turn, have been replaced by strategies of international cooperation and coordination of actions by all members of society to solve global problems of our time. The authors prove the importance of considering not only environmental, but also social aspects when developing sustainable development strategies to ensure social justice and improve the quality of life of all segments of society. In conclusion, the authors conclude that risk management related to economic instability, environmental changes and other factors requires new strategies for sustainable development, which in turn is impossible without effective public management, public involvement, and informed decision-making.

Towards Energy-Balance Closure with a Model of Dispersive Heat Fluxes

In the last decades the energy-balance-closure problem has been thoroughly investigated from different angles, resulting in approaches to reduce but not completely close the surface energy balance gap. Energy transport through secondary circulations has been identified as a major cause of the remaining energy imbalance, as it is not captured by eddy covariance measurements and can only be measured additionally with great effort. Several models have already been developed to close the energy balance gap that account for factors affecting the magnitude of the energy transport by secondary circulations. However, to our knowledge, there is currently no model that accounts for thermal surface heterogeneity and that can predict the transport of both sensible and latent energy. Using a machine-learning approach, we developed a new model of energy transport by secondary circulations based on a large data set of idealized large-eddy simulations covering a wide range of unstable atmospheric conditions and surface-heterogeneity scales. In this paper, we present the development of the model and show first results of the application on more realistic LES data and field measurements from the CHEESEHEAD19 project to get an impression of the performance of the model and how the application can be implemented on field measurements. A strength of the model is that it can be applied without additional measurements and, thus, can retroactively be applied to other eddy covariance measurements to model energy transport through secondary circulations. Our work provides a promising mechanistic energy balance closure approach to 30-min flux measurements.

Study of the relationship between large-amplitude neutral sheet oscillations and oblique firehose instabilities during fast flows in the terrestrial magnetotail

Flapping motions of the current sheet are a large-scale dynamic process in the terrestrial magnetotail. Some large-amplitude neutral sheet oscillations during fast flows are regarded as flapping motions. In recent years, simulation results suggested that oblique firehose instabilities might be one of their generation mechanisms during fast flows, but this lacks sufficient observational evidence. Here, we statistically investigate the relationship between large-amplitude neutral sheet oscillations and oblique firehose instabilities during fast flows based on observations of the magnetospheric multiscale mission. We find that they have a broad range of period T from 4 to 2000 s. In addition, their propagation velocities (wavelengths) tend to decrease (increase) with the increase in T. About ∼17.6% of the large-amplitude neutral sheet oscillation events are approximately stationary relative to the flow and are linear or quasi-linear polarization, which meets the characteristics of the magnetic field fluctuations generated by oblique firehose instabilities. The probabilities of the fast flows accompanied by large-amplitude neutral sheet oscillations and the probabilities of Cof < 0 (oblique firehose unstable condition) near the neutral sheet have a similar tendency. In addition, T tends to be smaller when Cof is more negative during fast flows. These results suggest that Cof can not only affect the occurrence of the large-amplitude neutral sheet oscillations in the fast flow, but also affect their periods. Our above findings support that oblique firehose instabilities are a generation mechanism of some large-amplitude neutral sheet oscillations during fast flows.

PROBLEMS AND PRIORITIES FOR PREVENTING UNDECLARED LABOUR IN UKRAINE

The purpose of the article is to identify the scale of undeclared labour in Ukraine and to study the problems, principles and prospects of its prevention in unstable socio-economic conditions. Methodology. In line with the EU and ILO methodology, the State Labour Service of Ukraine interprets undeclared labour as legal paid activity that is not fully or partially registered in accordance with the law. Results. Undeclared work plays an important role in the practice of business management and competitiveness stimulation in countries with industrial, neo-industrial and post-industrial economies, which has been developed almost since the middle of the 20th century. The paper proves that undeclared work is a broader concept that includes legalised (both official and manipulative) as well as shadowy mechanisms of its occurrence and functioning. Given the problematic performance by the State Labour Service of Ukraine of its inspection and sanctioning powers, as well as the widespread use of non-standard labour relations (with mediation in the performance of employer functions, outsourcing of auxiliary, service and some specialised personnel to companies), tariff-free remuneration systems encourage numerous manipulations in the area of labour declaration and decent wages. The source of problems with the spread of remuneration systems based on an assessment of the complexity of the work performed and the qualifications of employees, as well as with ensuring decent working conditions for agency (loan, temporary) workers, is the unclear legislative regulation of these systems. Practical implications. The priorities for preventing undeclared labour in Ukraine are: a consistent increase in the share of wages in the structure of production costs; strengthening cross-control over the fulfilment of obligations to pay the minimum wage under the tariff-free and hourly wage systems; and the introduction of a sound methodology for harmonising the minimum wage, the subsistence minimum and other basic social standards linked to them. Value/Оriginality. The expediency of identifying institutionalised and manipulative mechanisms of undeclared labour, their formal and illegal bases is confirmed by the classification of the main forms of undeclared labour used by the EU, ILO and the State Labour Service of Ukraine; this approach will increase the complexity and effectiveness of systemic measures to regulate it (control, mitigation, prevention).

Investment and Sustainability Incentives for Msmes

The government continues to make efforts to increase the role of Micro, Small and Medium Enterprises after Covid 19 as the national economy recovers. A number of economic policies that focus on improving the MSME sector are intended to ensure that this sector grows and develops again in the future. In the national economy, MSMEs continue to make a major contribution to economic development, job creation, equal distribution of people's income, and providing products and services for the community. On the other hand, MSMEs are a source of state revenue to finance development. In the midst of unstable economic conditions, efforts to increase Gross Domestic Product originating from this sector continue to be made. MSMEs are expected to grow again in the long term and become a source of sustainable financial potential. The government, through fiscal policy, provides wider space for MSMEs, the roots of which become economic society, which absorbs the workforce. Through fiscal policy, the government can provide investment incentives to MSMEs. This fiscal policy is aimed at providing relief in fulfilling tax obligations and encouraging MSME activities to grow and develop again after Covid 19, which has had a negative impact on MSMEs. Through incentives, MSMEs have more freedom to increase production. Investment incentives are also intended to increase the capacity of MSMEs to fulfill tax obligations.

A Systematic Investigation of the Applicability of Taylor’s Hypothesis in an Idealized Surface Layer

Taylor’s Frozen Turbulence Hypothesis (TH) is a critical assumption in turbulent theory and practice which allows time series of point measurements of turbulent variables to be translated to the spatial domain via the mean wind. Using a 3D array of fibre-optic distributed temperature sensing in the atmospheric surface layer over an idealized desert site we present a systematic investigation of the applicability of Taylor’s Hypothesis to atmospheric surface layer flows over a variety of conditions: unstable, near-neutral, and stable atmospheric stabilities; and multiple measurement heights between the surface and 3 m above ground level. Both spatially integrated and spatially scale-dependent eddy velocities are investigated by means of time-lagged streamwise two-point correlations and compared to the mean Eulerian wind. We find that eddies travel slower than predicted by TH at small spatial separations, as predicted by TH at separations typically between 5 and 16 m, and faster than predicted by TH at larger spatial separations. In unstable atmospheric conditions the spatial separation at which eddy velocity is larger than Eulerian velocity decreases with height.

Effect of pre-transplantation use of angiotensin-converting enzyme inhibitor or angiotensin receptor blocker in kidney transplant recipients-propensity score-matched analysis.

Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers (ACEi/ARBs) can cause acute kidney injury under dehydratation or inhemodynamically unstable conditions. Regarding kidney transplantation (KT), the risk of using ACEi/ARBs before surgery is not well established. Therefore, we evaluated the clinical outcomes to determine the effect of preoperative use of ACEi/ARBs on KT. We retrospectively collected 1187 patients who received living-donor KT between January 2017 and December 2021. We conducted a propensity score-matched analysis between the ACEi/ARB(+) and ACEi/ARB(-) groups and evaluated the effects of ACEi/ARBs on delayed graft function, post-KT renal function, hyperkalemia events, rejection, and graft survival. The ACEi/ARB(+) group showed a similar incidence of delayed graft function as the ACEi/ARB(-) group (1.8% vs. 1.0%, P = 0.362). The risk of delayed graft function was not upregulated in the ACEi/ARB(+) group after propensity score-matching (odds ratio: 0.50, 95% confidence interval (CI) 0.13-2.00). Postoperative creatinine levels and the slope of creatinine levels after KT also were not significantly different between the two groups (creatinine slope from POD#0 to POD#7: -0.73 ± 0.35 vs. -0.75 ± 0.32mg/dL/day, P = 0.464). Hyperkalemia did not occur more often in the ACEi/ARB(+) group than in the ACEi/ARB(-) group during perioperative days. Rejection-free survival (P = 0.920) and graft survival (P = 0.621) were not significantly different between the two groups. In KT, the preoperative use of ACEi/ARBs did not significantly affect clinical outcomes including delayed graft function, postoperative renal function, hyperkalemia events, incidence of rejection, and graft survival rates compared to the patients who did not receive ACEi/ARBs.

The article is devoted to considering the concepts of “emotional burnout syndrome” and “professional burnout” and determining their commonalities and differences in essence. It characterizations individuals’ reactions to systematic stress, which necessarily occurs during intense work, unstable working conditions, etc. These reactions include exhaustion, dehumanization (depersonalization, feelings of cynicism), and reduced work capacity. The following types of reactions of individuals to stress factors are additionally characterized: emotional imbalance, pessimistic attitude towards life, distancing, and disorganization. The common logic of behavioral reactions to stress and professional and emotional burnout symptoms is determined. The influence of emotional and professional burnout on personality conflict is determined. It is noted that behavioral reactions that are formed under the influence of a state of professional or emotional burnout can form factors of conflict of various types. Understanding the 12 stages (phases) of burnout is crucial for being informed and prepared. These stages, such as ‘Forced bringing to the point of no return’, ‘Overtime work ‘, ‘Closing’ of conflicts and needs’, ‘Suppression’ of conflicts and needs’, ‘Rethinking values ‘, ‘Activation of denial of problems’, ‘Retreat’, ‘Observation of changes in behavior ‘, ‘Loss of personality ‘, ‘Inner emptiness ‘, ‘Depression ‘, and ‘Complete exhaustion ‘, provide a roadmap for recognizing and managing burnout. The need to combine the efforts of the organization’s management and personnel in managing emotional and professional burnout is emphasized. The proposed strategy of personnel development in the field of management of emotional and professional burnout. Proposed methods of psychological self-help for personnel are unchanged regardless of their functional, professional, or role affiliation. Among such methods are effective time management in professional and personal spheres; organization and redistribution of professional workload; quality rest and sleep; proactive, empathetic, and assertive communication; breathing practices; practicing self-training techniques to control the emotional and volitional sphere; development of critical, creative, and positive thinking; self-development and time for hobbies; attention to one’s health. Keywords: emotional burnout, professional burnout, conflicts, stress, personnel, methods of psychological self-help.

Adaptive strategic analysis models in a volatile market: case studies of today’s organizations

Adaptive models of strategic analysis are crucial in unstable market conditions for modern organizations. These models assist organizations in identifying and responding to the changing business environment, ensuring their sustainable development and competitive market position. The use of adaptive management allows companies to make flexible and informed decisions considering the impact of digitalization on business relationships. Factors such as leadership, culture, structure, and business strategy play an essential role in supporting organizational changes and adaptation. This paper discusses the fundamentals of adaptive management, including models of strategic analysis and strategic management. It covers the theoretical foundations of adaptive management, organizational structures with an adaptive management type, adaptive analysis models, and provides examples of companies that employ various tools. Additionally, a model of adaptive organizational management is developed, enabling companies to evolve in uncertain conditions. This model includes three subsystems: diagnostic of premises, selection of the optimal option, and implementation of the strategic scenario. The article concludes that adaptive strategic management is quite relevant in the context of variability and high environmental uncertainty; however, the strategy should not remain static.

Ecological factors and morphological traits of Coffea Liberia Hiern in Kalipuro District, Banyuwangi Regency

This study aimed to analyze the ecological factors and morphological traits of Liberica coffee in Kalipuro District, Banyuwangi Regency. Ecological and morphological factors were measured, and observations were recorded accordingly. The observation of significant morphological characters has been thoroughly conducted The observed ecological factors were microclimate factors, including altitude, air temperature, humidity, light intensity, rainfall rate, soil pH, soil temperature, and soil moisture. The Paleontological Statistics (PAST) program was used to perform multivariate analysis to group liberica coffee variants based on morphological traits and physical factors of the plantation. The study found that physical environmental factors had a relatively significant influence on morphological variation in each population. The light intensity and relative humidity were the physical environmental factors related to morphological traits, such as leaf shape index, number of flowers per inflorescence, and leaf surface index based on principal component analysis (PCA). Unstable weather conditions can influence environmental factors, which, in turn, can profoundly impact morphological characteristics, specifically the flowering season. The study revealed a statistically significant correlation between light intensity and the number of flowers per inflorescence.

Controversies and Unconstitutional Practices of Elections Postponement in Indonesia: State Interest or Political Elite Interest?

The Indonesian political atmosphere has recently been shocked by controversial issues regarding the postponement of the Indonesian elections in 2024 nationally. The reason for postponing the election is due to the unstable economic condition of the country after COVID-19 so that it is considered incapable of holding elections in 2024. This study aims to find out how the postponement of elections is regulated in Indonesia, as well as whether the postponement of elections is a constitutional action or for the interests of groups elite. The results of this study indicate that basically the Indonesian Election Law does not specifically regulate the postponement of elections. The postponement of elections in the provisions of election law in Indonesia only regulates regional election delays. Meanwhile, national election delays are not adequately regulated. Therefore, nationally postponing the election is considered a violation of the Indonesian constitution. In addition, it is seen that the postponement of the election is not an aspiration of the Indonesian people so that it is considered an attempt by the political elite to take political advantage in the 2024 election.
