At the same time, recycling is seen as the most important environmental behavior that reduces the amount of solid waste and conserves resources. Considering the importance of recycling for a sustainable future, it is of great importance to determine the factors affecting the recycling behavior of individuals. Due to the rapid increase in environmental problems and their extremely negative impact on life, it is necessary to determine the environmental and recycling behaviors of individuals and produce solutions. In this study, attitudes and behaviors towards recycling were investigated with the help of a model proposed within the scope of Theory Planned Behavior (TPB). The analysis of the data was made using the Partial Least Squares Structural Equation Modeling (PLS-SEM) Smart-PLS software, which can be used successfully in small-volume samples and does not require the assumption of multivariate normality. It was determined because of PLS-SEM fit criteria that TPB is suitable for explaining recycling attitudes and behaviors. As a result of the analysis, it was revealed that attitude, subjective norm, and perceived behavioral control positively and significantly affect recycling intentions.

For this purpose, first, a research model was proposed to describe the relationships between the factors, and then, the proposed model was tested with the help of Partial Least Squares Structural Equation Modeling (PLS-SEM). In the study, the research model and hypotheses were designed with the assumption that information score on GWCC affects the knowledge and awareness, these effects increase the risk perception of GWCC, and as a result, the sense of responsibility and environmental behaviors are affected. It was seen that the highest coefficient of cause and effect relationship was between risk and awareness variables. It has been determined that a one-unit increase in awareness leads to a 0.638-unit increase in perceived risk. It has also been founded that a one-unit increase in the sense of responsibility for preventing GWCC will reflect on environmental behaviors and increase it by 0.557 units.

For this purpose, firstly, a research model was proposed to describe the relationships between attitudes and behaviors towards GMO by making use of the literature review, and then various hypotheses were formed to test the relationships between the factors in the model. The factors in the proposed research model are "Attitude (ATT), ""Attitude towards Knowledge and Technology (KNOW), " "Trust (TRUST), " "Perceived Benefit (BEN), " "Perceived Risk (RISK)" and "Behavior (BEH)". In the study, the proposed research model was analyzed using Structural Equation Modeling (SEM), and the suitability of the proposed model was evaluated according to various fit criteria. As a result of the analysis, it was determined that a one-unit increase in the perceived benefit and perceived risk for GMO will cause an increase of 0.89 units and a decrease of 0.19 units, respectively, in the attitude towards GMO. In addition, it was determined that as trust in scientific research results, media, labeling system and inspection systems increase, the perception that GMO can be beneficial will also increase.

A questionnaire has been conducted to 225 individuals, whowork at a desk job, in Istanbul. Structural Equation Modeling (SAM) has been used in the analysis of the data for the purpose of evaluating the conformity of the model and describing the relationship among the factors that affect the attitudes and behaviours regarding the use of CAM. In addition, frequency and percentage calculation were also included in the study in order to determine the knowledge levels of the individuals regarding CAM; which applications they need more and which factors affect them in using CAM. It has been observed as a result of the SAM Analysis that, the use of CAM is mostly affected by the latent variable regarding the use of CAM independent of the social impact.

In the proposed structural model, factors such as Visual Appeal, Escape from Reality, Flow Experience, Success, Enjoyment, Self-Efficacy, The Intention of Playing Games and Gaming Behaviour were discussed. In testing of the relationships between these factors included in the model, Structural Equation Modelling (SEM) was used. The fitting of the model was determined by evaluating various cohesion criteria for SEM in the literature. When the results obtained from the study were evaluated, it was seen that there was a statistically positive significant relationship between Visual Appeal latent variable and Pleasure intrinsic latent variable. According to this, the visual appeal of online game, visual design and the effect of the online game will be increased as the influence increases. Another result obtained from the study is that there is a statistically positive significant relationship between the latent variable of Escape from Reality and the intrinsic latent variable of Pleasure. The fact that players want to escape from reality, away from the stress of daily life and the events that make them unhappy, positively affects the pleasure of the players taken out of online games. There are often studies in the literature that affect the intention of playing online games. In this study, online gaming behavior was defined as an endogenous latent variable, and the factors affecting online gaming intention and behavior were extensively modeled.

In the proposed structural model, environmental illiteracy and environmental awareness were the exogenous latent variables, while pro-environmental attitude, pro-environmental behavior, and the purchase of environmentally friendly products were the endogenous latent variables. The latent variable of environmental illiteracy did not have a statistically significant effect on environmental attitudes and purchase of environmentally friendly products, whereas environmental awareness had a positive effect on pro-environmental attitudes and the purchase of environmentally friendly products. These findings indicate that students with environmental awareness also develop positive attitudes toward the environment, and the presence of a positive attitude toward the environment leads them to display pro-environmental behaviors and adopt a positive attitude toward environmentally friendly products.

To this end, a structural equation model is proposed. Environmental consciousness regarding the use of plastic bags, social pressure, support for the banning of plastic bags, the intention to use cloth bags and behavior to reduce plastic bag use are employed as latent variables in the model. The intention to use cloth bags and the behavior to reduce the use of plastic bags are defined as endogenous latent variables in the structural model. In the conclusion of the study, it is identified that consumers who are environmentally conscious and feel under social pressure, tend to reduce the use of plastic bags and switch to using cloth bags.

In addition to its environmental benefits, recycling is also an effective way to fundraise. Although recycling is commonplace in many countries, it is still relatively rare in Turkey. In this study, the attitudes and behaviors of housewives toward recycling were investigated using Ajzen's Theory of Planned Behavior (TPB) and the proposed Structural Equation Model (SEM). It was found that the Housewives' Recycling Model (HRM), obtained as a result of the analysis, could be employed to explain their recycling behavior. In particular, the research established that the positive ideas housewives have in terms of their perceived behavioral control and the individuals in their immediate social surroundings, whose opinions they value, have a positive impact on guiding their recycling behavior.

In the proposed structural model, environmental illiteracy and environmental awareness were the exogenous latent variables, while pro-environmental attitude, pro-environmental behavior, and the purchase of environmentally friendly products were the endogenous latent variables. The latent variable of environmental illiteracy did not have a statistically significant effect on environmental attitudes and purchase of environmentally friendly products, whereas environmental awareness had a positive effect on pro-environmental attitudes and the purchase of environmentally friendly products. These findings indicate that students with environmental awareness also develop positive attitudes toward the environment, and the presence of a positive attitude toward the environment leads them to display pro-environmental behaviors and adopt a positive attitude toward environmentally friendly products.

To this end, a structural equation model is proposed. Environmental consciousness regarding the use of plastic bags, social pressure, support for the banning of plastic bags, the intention to use cloth bags and behavior to reduce plastic bag use are employed as latent variables in the model. The intention to use cloth bags and the behavior to reduce the use of plastic bags are defined as endogenous latent variables in the structural model. In the conclusion of the study, it is identified that consumers who are environmentally conscious and feel under social pressure, tend to reduce the use of plastic bags and switch to using cloth bags.

In addition to its environmental benefits, recycling is also an effective way to fundraise. Although recycling is commonplace in many countries, it is still relatively rare in Turkey. In this study, the attitudes and behaviors of housewives toward recycling were investigated using Ajzen's Theory of Planned Behavior (TPB) and the proposed Structural Equation Model (SEM). It was found that the Housewives' Recycling Model (HRM), obtained as a result of the analysis, could be employed to explain their recycling behavior. In particular, the research established that the positive ideas housewives have in terms of their perceived behavioral control and the individuals in their immediate social surroundings, whose opinions they value, have a positive impact on guiding their recycling behavior.
