As evidenced, the EL model is the model that meets the two established criteria. The EL model applies to both formal and non-formal environmental education and refers essentially to the development of competent citizenship to understand the functioning of natural systems, the interaction between nature and humans and the ability to act in critical environmental issues (Roth 1992). Among the conclusions and recommendations made by different studies that have evaluated EL, the following stand out: The “knowledge” has a weak relationship and a minor contribution to explaining the variation in the environmental behavior of students. A much stronger relationship was found between values and attitudes and behaviors (Anton et al. 2015).The competence-based approach used by the EL model is useful to identify the capacities required in individuals to act in conditions in which a problem must be resolved (Corral-Verdugo 1994). The competent performance of effective action implies the mobilization of knowledge, cognitive and practical skills as well as social and behavioral components, such as attitudes, emotions, values and motivations. Competence is a holistic notion; therefore, it is not reducible to its cognitive dimension, making it clear that the terms “competence” and “ability” are not synonymous (Hollweg et al. 2011)It is necessary that the educational perspective on the issue of waste management is based on a preventive approach to avoid that promotion of recycling involves practices that increase consumption since students do not connect their consumption with environmental impacts (Goldman et al. 2013).

To start with, let us consider the case that plastic region overwhelms the the entire adhesive layer, in which the entire adhesive layer is undergoing plastic deformation. In this case, relative displacement will occur between the MP and RP until those two parts are totally disconnected, and the strength of the joint will increase linearly with the overlap length increasing. Then, the apparent plastic yield stress, can be simply given by where is the failure load, and is the effective action area of the shear stress. Usually, the specimens with relatively short overlap length tend to fail in this case.
A generalization of the Theory of Constraints: Choosing the optimal improvement option with consideration of variability and costs

As a strategic policy, the plant manager has decided to improve the performance of the production system to make the factory more competitive. To tackle the nuts, members of the technical staff are assigned by the manager to estimate possible improvement plans and their costs. Since changing process times may have negative impacts on product yields and quality, the plant manager decides to be a little conservative at the beginning, and first focus on optimizing the process of PM actions and repairs, reducing the duration and frequency of breakdowns or PM actions. According to the estimation of the technical staff members, the available improvement options and their corresponding costs () are listed in Table 1. Type A options reduce the mean of interruption durations, type B options reduce the SCV of interruption durations to zero, and type C options reduce the frequency of interruptions. Assume at most one option can be implemented during each improvement process. What is the most effective action to improve the plant performance or cycle time? Should we start from the system bottleneck based on TOC?

In this method, permanganate group is responsible for the effective action in the treatment of the cellulosic fibers. This treatment is carried out by socking different concentration of potassium permanganate for various time intervals after the alkali pre-treatment resulting in reduction of hydrophilic nature of the fiber and improving the surface roughness thereby leading to an increased fiber-matrix interaction (Bam et al., 2019).
