The current research aims to explore the impact of participative leadership represented by (decision-making participation, delegation of authority, human relations, and justice and equality) in human resource sustainability, defined by (human resource well-being, human resource development, human resource retention, and work-life Equilibrium). At the same time, testing the mediating role of the organizational Equilibrium variable represented by (contributions and inducements) in the influential relationship between the two variables. The study community comprised all employees working in private hospitals in the governorate, totaling approximately 650 individuals across 15 hospitals. Data were collected from a random sample of 306 medical staff members working in private hospitals in Duhok Governorate, Kurdistan Region, Iraq, using a questionnaire. The research employs a descriptive-analytical approach, and the results, analyzed using SPSS V.25, indicate a significant direct effect of both participative leadership and organizational Equilibrium on human resource sustainability. Furthermore, the findings confirm the potential of organizational Equilibrium as a partial mediator in the relationship between participative leadership and human resource sustainability. The study recommends that private hospital management enhance human resource sustainability by promoting participative leadership practices and leveraging the dimensions of organizational Equilibrium to achieve this goal..

The demands of controlling when meeting cutting-edge technology are quite high given its underlying principles, its prospective character, flexibility, but also the desire for transparency, ethics, and responsibility. Through controllers (expert accountants), in their roles as collaborators, reminders, relationship managers of top management, smart technologies will be truly put to good use as business intelligence tools, as trusted allies (digital assistants, AI copilots, AI generative chatbots, interactive dashboards with AI inserts). Of course, there will be obstacles, a certain amount of distrust related to the “black boxes” regarding creation, operation, possible reactions. Hence the multiplication of searches to find something safer, with fewer unknowns regarding the purpose, risk levels, possible discriminations. This is how we arrived at XAI — explainable artificial intelligence, but also at HITL — complex models in which human judgment is integrated. The two systems also have their limits (especially regarding the balance between accuracy and explainability), but it is certain that the degree of trust, openness, and understanding of users (towards algorithms, models, artificial intelligence in general) through these tools will further increase. Basically, both tools suggest the same thing: if employees are directly involved and helped to understand something from the arguments, from the behavior of machines (whether it is about machine learning models, neural networks, or deep learning), then there will be an interactive collaboration between specialists and machines that is particularly beneficial to each productive or functional segment, but also to the entire organization.

Este artigo analisa a possibilidade de complementariedade entre os traços do dinheiro em Simmel no tocante à perda de sentido cultural na modernidade ca-pitalista e as instabilidades financeiras cíclicas de Minsky, procurando estabelecer uma síntese explicativa ainda que sumária. Metodologicamente, o trabalho lan-çou mão de uma revisão de literatura que sistematizou a ideia de dinheiro e suas reverberações no pensamento sociológico de Georg Simmel e no pensamento econômico de Hyman Philip Minsky. Os resultados da pesquisa mostraram que o dinheiro revelou mudanças importantes sociais quando as fases da financeiriza-ção ciclicamente se alteravam, ampliando ou reduzindo os chamados intermediá-rios separadores do indivíduo e o objeto, sendo uma das mais relevantes observa-ções encontradas no estudo.

At the turn of the 19th and 20th centuries, Siberia once again became a “melting pot” that brought together representatives of diverse ethnic groups. The reasons for migration beyond the Urals were predominantly economic. This article examines how various social events in the first third of the 20th century affected the lives of Siberian Germans. Amid the agrarian crisis, Russian Germans engaged in agriculture were compelled to seek ways to survive within Russia. The modernization of the state resettlement policy in the early 20th century and the expansion of rail transport created favorable conditions for labor migration, as a result of which, by the mid-1910s, Siberia had become one of the most rapidly developing agrarian regions. German settlers played no small part in this process by establishing capitalist family-farm enterprises that served as models for Russian old-settlers and other migrants. The events of 1914–1922 disrupted the established rhythms of German rural life. The economic policies of the Bolsheviks who came to power precipitated famine in the first half of the 1920s. The German population suffered as well, which fueled growing emigration sentiment. Even so, the New Economic Policy (NEP) and the revival of cooperatives enabled a rapid recovery of small-scale commodity production. The All-Russian Mennonite Agricultural Union played an important role in this process. The gradual rollback of the NEP and the shift to a command-administrative economic model brought increasing pressure to bear on the German population, among which conservative-clerical sentiments predominated. By the late 1920s, this would trigger a new round of confrontation between Russian Germans and the Soviet state. This article will interest readers concerned with the history of ethnic minorities (Russian Germans) and nationalities policy in the 20th century.

We develop a dynamic model of economic complexity that endogenously generates a transition between unconditional and conditional convergence. In this model, convergence turns conditional as the capability intensity of activities rises. We solve the model analytically, deriving closed-form solutions for the boundary separating unconditional from conditional convergence and show that this model also explains the path-dependent diversification process known as the principle of relatedness. This model provides an explanation for transitions between conditional and unconditional convergence and path-dependent diversification.

In this chapter, an input-output economic model with multiple interactive economic systems is considered. The model captures the multi-dimensional nature of the economic sectors or industries in each economic system, the interdependencies among industries within an economic system and across different economic systems, and the influence of demand. To determine the equilibrium price structure of the model, a matrix-weighted updating algorithm is proposed. The equilibrium price structure is proved to be globally asymptotically achieved when certain joint conditions on the matrix-weighted graph and the input-output matrices are satisfied. The theoretical results are then supported by numerical simulations.

Autism spectrum disorder is the most used umbrella term for a myriad of neuro-degenerative/developmental conditions typified by inappropriate social behavior, lack of communication/comprehension skills, and restricted mental and emotional maturity. The intriguing factor of this disorder is attributed to the fact that it can be detected only by close monitoring of developmental milestones after childbirth. Moreover, the exact causes for the occurrence of this neurodevelopmental condition are still unknown. Besides, autism is prevalent across individuals irrespective of ethnicity, genetic/familial history, and economic/educational background. Although research suggests that autism is genetic in nature and early detection of this disorder can greatly enhance the independent lifestyle and societal adaptability of affected individuals, there is still a great dearth of information to support the statement of proven facts and figures. This research work places emphasis on the application of automated machine learning incorporated with feature ranking techniques to generate significant feature signatures for the early detection of autism. Publicly available datasets based on the Q-chat scores of individuals across diverse age groups—toddlers, children, adolescents, and adults have been employed in this study. A machine learning framework based on automated hyperparameter optimization is proposed in this work to rank the potential nonclinical markers for autism. Moreover, this study aimed at ranking the AutoML models based on Mathew's correlation coefficient and balanced accuracy via which nonclinical markers were identified from these datasets. Besides, the feature signatures and their significance in distinguishing between classes are being reported for the first time in autism detection. The proposed framework yielded ∼90% MCC and ∼95% balanced accuracy across all four age groups of autism datasets. Deep learning approaches have yielded a maximum of 92.7% accuracy on the same datasets but are limited in their ability to extract significant markers, have not reported on MCC for unbalanced data, and cannot adapt automatically to new data entries. However, AutoML approaches are more flexible, easier to implement, and provide automated optimization, thereby yielding the highest accuracy with minimal user intervention.

Trauma exposure is one of the most important and prevalent risk factors for mental and physical ill-health. Prolonged or excessive stress exposure increases the risk of a wide variety of mental and physical symptoms, resulting in a condition known as post-traumatic stress disorder (PTSD). The diagnosis might be challenging due to the complex pathophysiology and co-existence with other mental disorders. The prime factor for PTSD development is exposure to a stressor, which variably, along with peritraumatic conditions, affects disease progression and severity. Additionally, many factors are thought to influence the response to the stressor, and hence reshape the natural history and course of the disease. With sufficient knowledge about the disease, preventive and intervenient methods can be implemented to improve the quality of life of the patients and to limit both the medical and economic burden of the disease. This literature review provides a highlight of up-to-date literature on traumatic stress, with a focus on causes or triggers of stress, factors that influence response to stress, disease burden, and the application of the social-ecological public health model of disease prevention. In addition, it addresses therapeutic aspects, ethnic differences in traumatic stress, and future perspectives, including potential biomarkers.

This paper addresses an optimal control problem governed by a rate independent evolution involving an integral operator. Its particular feature is that the dissipation potential depends on the history of the state. Because of the non-smooth nature of the system, the application of standard adjoint calculus is excluded. We derive optimality conditions in qualified form by approximating the original problem by viscous models. Though these problems preserve the non-smoothness, optimality conditions equivalent to the first-order necessary optimality conditions can be provided in the viscous case. Letting the viscous parameter vanish then yields an optimality system for the original control problem. If the optimal state at the end of the process is not smaller than the desired state, the limit optimality conditions are complete.

John Clark was inventor of the Eureka machine to generate hexameter Latin verse. He labored for 13 years from 1832 to implement the device that could compose at random over 26 million different lines of well-formed verse. This paper proposes that Clark should be regarded as an early cognitive scientist. Clark described his machine as an illustration of a theory of "kaleidoscopic evolution" whereby the Latin verse is "conceived in the mind of the machine" then mechanically produced and displayed. We describe the background to automated generation of verse, the design and mechanics of Eureka, its reception in London in 1845 and its place in the history of language generation by machine. The article interprets Clark's theory of kaleidoscopic evolution in terms of modern cognitive science. It suggests that Clark has not been given the recognition he deserves as a pioneer of computational creativity.

Este artículo ofrece evidencia del papel positivo que la reducción de la desigualdad de género ejerce en el crecimiento económico de los países centroamericanos. La metodología de análisis consiste en la estimación de ecuaciones por medio de mínimos cuadrados ordinarios, usando una sección cruzada de datos de 2017, de diecisiete países latinoamericanos. Se desarrolló un modelo de interdependencia económica para los países centroamericanos, con resultados que revelan que la reducción de la desigualdad de género en un país concreto conduce al aumento de su PIB y los de los otros países. Este tema no ha sido analizado en la literatura de la integración económica. La implicación es que los países pueden encontrar un medio para dinamizar sus economías, en la reducción de la desigualdad de género.
