Using a regioselectivity descriptor known as Fukui indices, this theoretical study examines the reactivity of cycloaddition processes of benzamide (PhCONH2) and chlorocarbonylsulfenyl chloride (ClCOSCl) at the level of base 6-311 G (d. p) by use of the DFT approach. Therefore, the attack of the sulfur atom on nitrogen and carbon on oxygen is kinetically more preferred than the assault of the sulfur atom on oxygen and carbon on nitrogen, as we have observed from our study. The electrophilic Δω difference between chlorocarbonylsulfenyl chloride and benzamide is 1.3726 eV. This indicates that the reaction under investigation has a polar nature (Δω > 1). on oxygen and carbon on nitrogen, as we have observed from our study. We have also studied the stereoselectivity and feasibility of these reactions from a thermodynamic and orbital point of view. The transition states of this reaction have been determined.

This study took the Human Capital Theory as a theoretical perspective to empirically investigate the role of supervisors' supervision in moderating the effect of professionalism and creativity on the performance of public high school teachers in Pekanbaru. The research respondents were 144 teachers, the data were processed using the PLS Structural Equation Modeling (SEM). The study proposed supervisors' supervision as a strategy to improve teacher performance. The results of the study show that professionalism and creativity affect teacher performance—supervisors' supervision plays a role in strengthening teacher performance. These results strengthen the Human Capital Theory stating that a combination of knowledge, skills, innovation, and a person's ability to carry out their duties can create value to achieve goals.

This study analyzes the relationships between knowledge sharing culture, information technology support, and process innovation on supply chain sustainability in Indonesia's digital printing SMEs, with market uncertainty as a moderating variable. Employing an explanatory approach, the research utilizes a cross-sectional survey involving 225 SME owners. Data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The findings reveal that knowledge sharing culture has a significant positive impact on both process innovation and supply chain sustainability. Conversely, information technology support negatively affects these two variables. Process innovation positively contributes to supply chain sustainability, albeit with a small effect. Market uncertainty strengthens supply chain sustainability but weakens the relationship between process innovation and sustainability. The mediating role of knowledge sharing culture through process innovation highlights a critical pathway for enhancing supply chain sustainability. This study offers theoretical and practical implications regarding the importance of knowledge sharing culture and process innovation, alongside challenges in technology adoption. The study's limitations include its cross-sectional approach a

Oxadiazoles, a class of nitrogen-containing heterocycles, exhibit diverse applications in pharmaceuticals, industry, and other fields. This study employs Density Functional Theory (DFT) to investigate the structural, electronic, and spectroscopic properties of four oxadiazole isomers.

One of the problems students often face is the lack of understanding of their interests and talents which will cause confusion in making future study choices and career plans. Career selection is an expression of personality into the world of work followed by identification of certain occupational stereotypes. Eight intelligences according to dr. Howard Gardner is linguistic, logical, mathematical, visual spatial, musical, kinesthetic, interpersonal, intrapersonal, and naturalist. This research purpose is to develop a system that produces information and professional recommendations that are in accordance with multiple intelligences of prospective high school students using a combination of Bayes' theorem and weighted product (WP) method. User’s preference value is calculated using the Bayes Theorem method to give each multiple intelligence value which is a criterion. WP method calculation to find professions that match user preferences. Weight of each criterion needed in WP method is calculated by Rank Order Centroid method. WP calculation will produce a ranking of 3 professions according to the input from the user. From system testing results that compared to results from experts, an accuracy of 67.33% is obtained. Based on the accuracy value, it can be said that the accuracy level system is quite good.

In practical scheduling problems, some factors such as depreciation cost, green costs like the amount of energy consumption or carbon emission, other resources consumption, raw material cost, etc., are not explicitly related to the machine processing times. Most of these factors can be generally considered as machine costs. Considering the machine cost as another objective alongside the other classical time-driven decision objectives can be an attractive work in scheduling problems. However, this subject has not been discussed thoroughly in the literature for the case the machines have fixed processing costs. This paper investigates a general unrelated parallel machine scheduling problem with the machine processing cost. In this problem, it is assumed that processing a job on a machine incurs a particular cost in addition to processing time. The considered objectives are the makespan and the total cost, which are minimized simultaneously to obtain Pareto optimal solutions. The efficacy of the mathematical programming approach to solve the considered problem is evaluated rigorously in this paper. In this respect, a multiobjective solution procedure is proposed to generate a set of appropriate Pareto solutions for the decision-maker based on the mathematical programming approach. In this procedure, the ϵ-constraint method is first used to convert the bi-objective optimization problem into single-objective problems by transferring the makespan to the set of constraints. Then, the single-objective problems are solved using the CPLEX software. Moreover, some strategies are also used to reduce the solution time of the problem. At the end of the paper, comprehensive numerical experiments are conducted to evaluate the performance of the proposed multiobjective solution procedure. A vast range of problem sizes is selected for the test problems, up to 50 machines and 500 jobs. Furthermore, some rigorous analyses are performed to significantly restrict the patterns of generating processing time and cost parameters for the problem instances. The experimental results demonstrate the mathematical programming solution approach's efficacy in solving the problem. It is observed that even for large-scale problems, a diverse set of uniformly distributed Pareto solutions can be generated in a reasonable time with the gaps from the optimality less than 0.03 most of the time.

The Central Coast of Vietnam, spanning from Thanh Hoa province to Binh Thuan province, holds a highly significant political and economic position, with the marine economy making substantial contributions to the existence and development of the region. This study aims to identify the factors influencing marine economic development (MED), evaluate the extent of influence of each factor, and determine whether security and coastal defense (SCD) plays an intermediary role in the development of the marine economy in the Central Coast provinces of Vietnam. The research conducted a typical survey of 268 fishermen engaged in marine economic activities, including aquaculture and the exploitation of aquatic resources, across the coastal provinces of the Central Coast of Vietnam. The collected data was analyzed using the structural equation modeling method through PLS-SEM software. The results of the study indicate that six factors have a direct and positive impact on MED. These factors, ranked by decreasing levels of influence, are: SCD (β = 0.412), Policy and Management (PM) (β = 0.329), Human Resources (HR) and Marine Infrastructure (MI) (both β = 0.268), Marine Resources (MR) (β = 0.204), and the lowest, Technology and Protection of Marine Environment (TPME) (β = 0.152). Additionally, the findings reveal that the three factors are HR, PM, and MI positively influence the SCD variable, with the levels of influence ranked as follows: HR (β = 0.272), PM (β = 0.224), and MI (β = 0.166). Moreover, at a significance level of 5%, all independent variables (HR, PM, and MI) exhibit statistically significant indirect relationships with MED through the SCD variable, confirming that SCD serves as an intermediary in the relationship with MED. Based on these findings, the study proposes managerial implications to support the development of the marine economy in the Central Coast provinces of Vietnam.

There are few studies addressing the mediating effect of readiness in supply chains in developing countries. We use the theory of dynamic capabilities to investigate the impact of integration (INT) on readiness (REA) and on innovative product performance (IPP) and to examine the mediating effect of REA on INT and IPP. We conducted a survey with a sample of 213 supply chain (SC) managers of machinery and equipment for transport and lifting heavy loads in Brazil. To this end, we used structural equation modeling to test the hypotheses and PROCESS macro to confirm the indirect effect. The empirical results indicate a significant effect between INT and REA and REA and IPP. However, the indirect impact of REA was compromised. The literature review demonstrates that the microfoundations of dynamic capabilities (Sensing, Seizing and Reconfiguration) strengthen supply chain links, particularly between INT, REA and IPP. This article helps managers understand the functioning of SC routines and operations. To this end, they should develop strategies that strengthen SC ties with INT, REA and IPP to face future crises. This paper advances the findings on integration, readiness, and innovative product performance in an SC. The findings provide insightful implications for managers to improve their strategies. In doing so, we theorize how the microfoundations of dynamic capabilities support the efficiency of supply chain operations.

Compound 5d proved to be the most potent anti-inflammatory and antibacterial agent. The analgesic activity, however, was maximum in compound 5e. The structural integrity of the synthesized compounds was ascertained using elemental analysis, infrared spectroscopy (IR), and proton nuclear magnetic resonance spectroscopy (¹H NMR).

Consumer awareness is one where the buyer could take the right decision in purchasing all types of product. Marketers in view of earning profit, neglect the interest of the consumers and this leads to exploitation of the buyers. To investigate the current scenario, this study focused on the consumer awareness in the urban and rural area towards the Fast Moving Consumer Goods (FMCG) along with the exploitation if any that existed in the market. For this purpose, 557 consumers who were using FMCG products residing in the western region of Tamilnadu were selected through cluster sampling followed by simple random sampling. To meet out the objectives, various statistical tools through SPSS 21 were applied and the result revealed that all the constructs like communication, price, labeling, promotion and unfair trade practices, if any remarkably influencing the consumer awareness. Also, labeling has a noteworthy mediating role between consumer awareness and satisfaction. But there existed a direct negative effect of consumer awareness on the satisfaction. It is suggested that marketers need to focus to fulfill all the rights of the consumers as detailed in the consumerism.
