Digital Transformation in HRM: Leveraging AI and Big Data for Employee Engagement and Retention

The Jordanian banking sector is now seeing a significant change in the use of artificial intelligence (AI) and big data in human resource management (HRM). To assess the influence of this era on employee engagement and retention, 300 employees of Jordanian bank were the sample of the study. Using partial least squares (PLS) structural equation modeling, we have a look at investigating how pride mediates and organizational culture modifies those effects. The study found a favorable correlation between AI adoption (r = 0.65, p < 0.01) and Big Data use (r = 0.58, p < 0.05) and work satisfaction, organizational culture, savings technology, staff engagement, and positive connections with Jordanian savings banks. Furthermore, regression research demonstrates that AI adoption and usage of Big Data are predictive. AI and big data can optimize HRM practices and provide insights, leading to higher employee satisfaction (r = 0.72, p < 0.01). This can enhance competitive advantage and strategy in the digital age.

Research on Boiler Energy Saving Technology Based on Internet of Things Data

This paper proposes a heat demand prediction model that analyzes the heat behavior of heat users, and analyzes the heat behavior data of heat users through a clustering algorithm to predict their heat demand. This paper is based on the supply-demand balance strategy to reduce the heat loss during the transmission of heat medium, and then improve the energy-saving efficiency of the boiler. The traditional boiler energy-saving and consumption reduction method is to optimize the boiler combustion parameters, improve the fuel combustion efficiency and waste heat recovery technology through the Internet of Things and big data technology. The method of balancing the heat-using end with the load of the boiler at low usage frequency is seldom considered. Therefore, this paper predicts the heat demand of the heat-using end by analyzing its thermal behavior, and balances the heat demand and boiler heat supply under the condition of meeting the heat demand. Finally, through simulation experiments, the validity of the model is verified, and the trend and data can be well predicted in the short-term heat demand prediction.

Collateralized Marriage

Marriage rates have become increasingly stratified by homeownership. We investigate this in a household model where investments in public goods reduce future earnings and, thus, divorce risk creates inefficiencies. Access to a joint savings technology, like a house, collateralizes marriage, providing insurance to the lower-earning partner and increasing specialization, public goods, and value from marriage. We use idiosyncratic variation in housing prices to show that homeownership access indeed leads to greater specialization. The model also predicts that policies that erode the marriage contract in other ways will make wealth a more important determinant of marriage, which we confirm empirically.

Irrigation technology adaptation for a sustainable agriculture: A panel endogenous switching analysis on the Italian farmland productivity

Efficient water management in agricultural activities can improve local water resource conditions while enhancing farms’ economic performance. This paper analyses how farmers’ decisions to adopt innovative and sustainable irrigation systems, such as Water Conservation and Saving Technologies (WCSTs), would shape Italian farms’ economic resilience by improving land productivity. Using a Panel Endogenous Switching Regression Model, our results confirm that the WCST adoption is an endogenous and self-selective process and land value is endogenously determined. Seasonal aridity indices are important factors in the choice of WCST adoption, with different effects on non-adopters and adopters. Farmers who adopt WCSTs are more productive than those who do not.

Development of Drying Energy Saving Technology of Paperboard by Applying Precipitated Calcium Carbonate Made from Oyster-Shell Byproducts

In this study, we aimed to identify the possibility of the internal application of a precipitated calcium carbonate made from oyster shell byproducts (O-shell PCC) for reducing the drying energy in paperboard mills. The micro-fibrillated cellulose (MFC) was also applied to improve the strength of the paperboard containing O-shell PCC. The O-shell PCC was classified through an 80 mesh screen and then its SEM image, particle size, and zeta potential were analyzed. After the MFC was prepared by micro-grinding hardwood bleached kraft pulp (Hw-BKP), its particle size, viscosity, and fiber width were also measured. The O-shell PCC and MFC were added to the Korean old corrugated container (KOCC) stock to prepare handsheets, and their physical properties and drying energy reduction were measured to determine the effect of the O-shell PCC and MFC on the drying energy saving. The O-shell PCC was effective to improve the bulk and drying energy reduction of handsheets, but the strengths decreased. The MFC was effective in improving the strength, but more drying energy was required as the addition of MFC increased due to its hydrophilic property. In addition, the application of the PCC and MFC, which had not been used in paperboard mills, could increase the production cost. However, the reduced cost of drying energy was estimated to be more than the increased cost of PCC and MFC at the optimum dosage (6% O-shell PCC and 0.2% MFC on o.d. fiber). Therefore, it was concluded that the combination of O-shell PCC and MFC could be effective in saving drying energy in paperboard mills.

BIM Building HVAC Energy Saving Technology Based on Fractional Differential Equation

Abstract This article uses BIM technology to simulate HVAC in a commercial building. And use fractional differential equations to verify the set temperature, humidity, and other related parameters. The experiment takes an air-conditioned room model as the research object and uses the thermodynamic characteristics to establish a dynamic mathematical model of differential equations. Research shows that the multiple electric heat pump equipment aggregation groups discussed in this article are a good resource for user-side demand response. The air-side flow rate disturbance of the building HVAC has the greatest impact on the heat transfer of the surface cooler. As the air velocity increases, the rate of increase in heat exchange will decrease.

Can Energy Efficiency Help in Achieving Carbon-Neutrality Pledges? A Developing Country Perspective Using Dynamic ARDL Simulations

The current research sheds light on the nexus between environmental degradation as proxied by carbon dioxide emissions (CO2), energy efficiency (EE), economic growth, manufacturing value-added (MVA), and the interaction effect of EE and MVA in India. Using yearly data from 1980 to 2019, the current study employs dynamic auto-regressive distribution lag (DARDL) simulations and Fourier Toda and Yamamoto causality techniques. The findings of DARDL reveal that as income and MVA rise, environmental quality decreases, while EE improves environmental conditions in both the long and short run. Surprisingly, the interaction term of EE and MVA has a detrimental influence on environmental quality, meaning that India remains unable to provide energy savings technologies to the manufacturing industry. Furthermore, the environmental Kuznets curve (EKC) hypothesis is well-founded for India, as the long-run income coefficient is smaller than the short-run coefficient, implying that India is in its scale stage of economy, where economic growth is prioritized over environmental quality. The results of the causality technique reveal that CO2 emissions and EE have a bidirectional association. Therefore, policymakers in India should embrace realistic industrialization strategies combined with moderate decarbonization and energy efficiency initiatives under the umbrella of sustainable industrial and economic growth.
