What is pls-sem?5 answersPartial Least Squares Structural Equation Modeling (PLS-SEM) is a statistical method used in various fields like social sciences, information systems, and research on career adaptability and technological services demand. PLS-SEM allows for analyzing multiple variables simultaneously, handling complex causal relationships, and examining direct and indirect effects among latent variables. It is particularly beneficial when dealing with a large number of variables and limited sample sizes. PLS-SEM offers flexibility, predictive power, and the ability to quantify uncertainty induced by introducing mediators in path models, aiding in decision-making regarding mediator inclusion. It is utilized in workshops to enhance research methodology knowledge and improve scientific article writing skills.
What are the advantages of SEM?4 answersThe advantages of scanning electron microscopy (SEM) include its ability to provide imaging at various magnifications, ranging from 1 µm to 1 nm, depending on the hardware used. SEM allows for the scanning of surfaces and the collection of information on topographical contrast, material contrast, and compositional information through the emission of different signals. The simultaneous acquisition of secondary electrons and x-rays in SEM results in images with different spatial resolutions, which can be improved by reducing the accelerating voltage. SEM is a powerful imaging instrument that integrates with an energy-dispersive spectrometer for elemental analysis at the specimen surface. It is applicable to both experimental and non-experimental research, providing a confirmatory factor analysis approach to examine relationships among latent variables indicated by multiple observable variables. SEM is a robust and comprehensive analytical technique that can strengthen and increase the accuracy of analyses in medical and health research. Additionally, SEM is widely used in various research areas and industry sectors to study nanoscale features of samples and investigate biological samples.
What is PLS SEM?4 answersPartial least squares structural equation modeling (PLS-SEM) is a statistical technique used to examine complex relationships among variables. It combines the strengths of structural equation modeling (SEM) and partial least squares regression (PLS) to model relationships between latent variables. PLS-SEM is particularly useful when there are a large number of variables and a limited sample size. It can handle both formative and reflective measures, model many variables and relationships, and has good statistical prediction capacity. However, PLS-SEM has some limitations, including biased estimates and a lack of measurement error estimation and model fit assessment tools. Despite these limitations, PLS-SEM has been underutilized in certain fields, such as leisure research. Researchers and journal editors can benefit from understanding the strengths and limitations of PLS-SEM and its potential applications in different sub-fields and theories.
What are the strengths and weaknesses of SEM in business research?5 answersSmall and medium-sized enterprises (SMEs) have strengths and weaknesses in business research. On the positive side, SMEs have higher innovation efficiency compared to large corporations due to their flexible organization and strong adaptability. Additionally, SMEs play important roles in the growth of economics and increasing employment. However, SMEs also face challenges such as limited scale and resources, which make it difficult for them to bear enormous pressure on research and development. Furthermore, SMEs must satisfy strict requirements from buyers regarding quality, price, and delivery. Despite these challenges, effective measures for innovative collaboration and risk management can enhance SME performance and contribute to the body of knowledge in business research.
