Cultivating in greenhouses constitutes a fundamental tool for the development of high-quality crops with a high degree of profitability. Prediction and control models guarantee the correct management of environment variables, for which fuzzy inference systems have been successfully implemented. The purpose of this review is determining the various relationships in fuzzy inference systems currently used for the modelling, prediction, and control of humidity in greenhouses and how they have changed over time to be able to develop more robust and easier to understand models. The methodology follows the PRISMA work guide. A total of 93 investigations in 4 academic databases were reviewed; their bibliometric aspects, which contribute to the objective of the investigation, were extracted and analysed. It was finally concluded that the development of models based in Mamdani fuzzy inference systems, integrated with optimization and fuzzy clustering techniques, and following strategies such as model-based predictive control guarantee high levels of precision and interpretability.

AbstractThe Bayesian paradigm for parameter estimation is introduced and linked to the main problem of genomic-enabled prediction to predict the trait of interest of the non-phenotyped individuals from genotypic information, environment variables, or other information (covariates). In this situation, a convenient practice is to include the individuals to be predicted in the posterior distribution to be sampled. We explained how the Bayesian Ridge regression method is derived and exemplified with data from plant breeding genomic selection. Other Bayesian methods (Bayes A, Bayes B, Bayes C, and Bayesian Lasso) were also described and exemplified for genome-based prediction. The chapter presented several examples that were implemented in the Bayesian generalized linear regression (BGLR) library for continuous response variables. The predictor under all these Bayesian methods includes main effects (of environments and genotypes) as well as interaction terms related to genotype × environment interaction.

This study aims to determine the effect of the work environment and leadership style on employee job satisfaction in hospitals in the city of Cimahi. This study used a descriptive verification approach, and 91 employees were sampled using multiple regression analysis assisted by SPSS 23 software. The primary data of this study were obtained from questionnaires and interviews. While secondary data is obtained through notes and publications as well as literature. The results showed that there was an influence between work environment variables and leadership style on employee job satisfaction at health service hospitals. The influence of the work environment has an influence on employee job satisfaction so that employees are committed and loyal to the organization. Meanwhile, a good leadership style can increase employee job satisfaction. This is also evidenced by the Adjusted R Square value of 0.571 or 57.1%.

Studies have shown that street network centrality measures are capable of explaining a significant proportion of pedestrian activity. These studies typically employ street centreline networks that differ significantly from the networks that pedestrians use to traverse the built environment. Presently, centrality approaches are rarely applied to dedicated pedestrian network (DPNs). This creates uncertainty regarding their ability to explain pedestrian activity when derived from DPNs. This study addresses that gap by investigating the extent to which centrality metrics derived from DPNs can explain observed pedestrian densities, both alone and when controlling for other built environment variables in metro station environments in Asia. In total, four DPNs were created centred on metro stations in Bangkok, Manila, Osaka, and Taipei chosen to represent different urban typologies. Multivariate results show that centrality metrics alone explain a mere 6–24% of observed pedestrian densities when calculated on DPNs. When all factors are considered, the contribution of centrality remained consistent in most study sites but is somewhat reduced with land-use variables and proximity to rail transit revealed as the strongest predictors of pedestrian density. Pedestrian design factors were also frequently associated with pedestrian density. Finally, stronger associations between centrality and pedestrian densities were observed in the denser, more complex pedestrian environments. These findings provide insight into the performance of centrality measures applied to DPNs expanding pedestrian network research in this area.

Leaf traits play key roles in plant resource acquisition and ecosystem processes; however, whether the effects of environment and phylogeny on leaf traits differ between herbaceous and woody species remains unclear. To address this, in this study, we collected data for five key leaf traits from 1,819 angiosperm species across 530 sites in China. The leaf traits included specific leaf area, leaf dry matter content, leaf area, leaf N concentration, and leaf P concentration, all of which are closely related to trade-offs between resource uptake and leaf construction. We quantified the relative contributions of environment variables and phylogeny to leaf trait variation for all species, as well as for herbaceous and woody species separately. We found that environmental factors explained most of the variation (44.4–65.5%) in leaf traits (compared with 3.9–23.3% for phylogeny). Climate variability and seasonality variables, in particular, mean temperature of the warmest and coldest seasons of a year (MTWM/MTWQ and MTCM/MTCQ) and mean precipitation in the wettest and driest seasons of a year (MPWM/MPWQ and MPDM/MPDQ), were more important drivers of leaf trait variation than mean annual temperature (MAT) and mean annual precipitation (MAP). Furthermore, the responses of leaf traits to environment variables and phylogeny differed between herbaceous and woody species. Our study demonstrated the different effects of environment variables and phylogeny on leaf traits among different plant growth forms, which is expected to advance the understanding of plant adaptive strategies and trait evolution under different environmental conditions.

Organizational culture is a central concept in research due to its importance in organizational functioning and suffering of employees. To better manage suffering, it is necessary to better understand the intrinsic characteristics of each type of culture and also its relationships with the environment. In this study, we used the multiple regression analysis to analyze the capacity of eight environment variables, five business strategies, and eight organizational competencies to predict the presence of Clan, Market, and Hierarchy cultures (Cameron and Quinn, 1999) in a subsample of Spanish managers (n1 = 362) and a subsample of Peruvian managers (n2 = 1,317). Contrary to what most of the literature suggests, we found almost no relationship between the environmental variables and the culture types. Strategy and competencies, in contrast, do have a significant predictive capacity, showing 9 links with the Clan culture, 7 with the Hierarchy culture, and 10 with the Market culture. In conclusion, this study has found the important characteristics of the types of organizational culture that could be useful to better manage the suffering of employees.

Abstract Human create the environment and, finally, environment shape the human’s character. The quality of life are strongly affected by state of person and environment in which it is lived. How long the process of integrity, what someone goes through, will affect the level of change to their lifestyle and that will affect to their next quality of life. Even though, these parameters can’t be used to measure the quality of life of the children. The world of children is a multidimensional world. Several domains and dimensions used as approach will determine whether there is improvement in their lives. This study is to show the influence of children’s creativity and creative environment on their quality of life. The importance of this study is to form a critical community mindset in creating a creative environment through architectural elements, so that it can improve the children’s growth and development, and finally it will impact to improve their quality of life. Bivariate and Multivariate correlational was used to prove the relationship between children’s creativity and creative environment variables with quality of life. The results of this study indicate that children’s creativity and the creative environment are strongly effect to improving children’s quality of life.

The purpose of this research is to examine the paradigm change of governance implementation. The governance is the implementation of Regional Autonomy which refers to Law No. 32 of 2004 about the performance improvement of autonomous government agencies. It puts the vision, mission, and strategy into actions that confirm the success or failure levels when carrying out activities following the specified programs and policies. There are variables applied to assess the civil servants’ performance achievement. This research focused on the variables that affect the work environment, organizational culture, job satisfaction, and work motivation. The respondents of this research are officials of Echelon III and IV at 14 Autonomous Regional Agencies in the Pamekasan Regency. The number of samples in this study comprised 120 Echelon III and IV officials. Structural Equation Method (SEM) was applied to test the causal relationship between work environment variables, organizational culture, work motivation, job satisfaction, and performance with the aid of the AMOS 20.0 program. The findings indicated (1) the work environment has a significant effect on job satisfaction and performance but has no significant effect on work motivation; (2) organizational culture has a significant impact on job satisfaction and performance but has no significant effect on work motivation; (3) job satisfaction has a significant effect on performance but has no significant effect on work motivation; (4) work motivation has a significant impact on performance but it has no significant effect on work motivation.
