As it involves systems of rather distinct nature, its analysis creates additional difficulties in any .. programs involve formal relations and intentionality depends on causal relations.

A relationship refers to the correspondence between two variables. When we talk about types of relationships, we can mean that in at least two ways: the nature of the between a simple correlational relationship and a causal relationship.
Among a population of technical-administrative workers at the university, we approached workers that were present at the workplace.
Of those technical-administrative workers convenience sample31 were on medical leave of absence, five were licensed to train or were qualified professionals, and two were working at another institution.
We thus considered subjects to be eligible.

The dependent variable of work ability was obtained through answers given by the workers to the WAI survey, which was developed by researchers in Finland [ 1 ]. Based on the score, work ability is classified as follows: As proposed by Raffone and Hennington [ 15 ], the dependent variable was categorized as reduced work ability 7—36 and good work ability 37—49 for comparison with the other study variables.
The independent variables sociodemographic, occupational, and health conditions and life habits were chosen in accordance with previous studies [ 25711 ]; they were based on questions about the following: The variables of sex and age are also important control variables.
The independent variables were measured using items from the following instruments: We employed the demand—control model to analyze the stressors of work based on work demands and employee control over those demands. That model was elaborated by Karasek and Theorell [ 2021 ]. Social support in the workplace was added to the model by Johnson and Hall in [ 22 ] as a means of assessing interaction between employees and managers toward work achievement [ 23 ]. All the above instruments have been tested and validated for Brazil by Matsudo et al.
Data entry and univariate analysis were performed by means of SPSS programme version Our analysis adopted the following steps: It was expected that the identified associations would promote the discussion about factors associated with work ability and that the results would support or refute the associations established in previous studies with other professional categories. We believed that our findings would allow us to recommend actions to reduce, control, or prevent diminishing work ability as well as actions to improve it.
All participants read and signed an informed voluntary consent form after being apprised of the goals of the research and its confidential, voluntary nature. Results In this study, there was a proportional distribution of gender, with Most of the respondents were married or in a civil union Over half of the participants Most subjects did not show any signs or symptoms of depression With respect to smoking habits, most did not smoke or had never smoked According to the performed classification for alcohol, the predominant categories were abstinence or risk-free consumption Trees were tagged, identified to species level and their diameter was measured.
Species ecological groups Evaluating species into ecological groups is useful to understand how communities differ in species composition e.
In forestry studies, species are usually classified according to their light requirements to establish and survive [ 3240 ]. Thus, we classified species into two successional groups according to the forest inventory data of Minas Gerais state [ 41 ] as pioneer species Pthat have high light requirements for successful establishment, growth and survival; and non-pioneer species NP that can establish and survive in shaded conditions.
Types of Relationships
We acknowledge that non-pioneer or shade tolerant species can have a range of life strategies, as some have the ability to establish and survive in the shade during the whole life, whereas others establish in the shade but require a gap to grow to larger sizes [ 32 ]. However, most forestry studies have focused on the classical trade-off between pioneer species fast-growing species with short life span and shade tolerant species slow-growing species with long life span to explain ecosystem processes [ 4243 ].

Additional information on species sampled and their classification into successional groups can be found in S1 Table. Data analysis We evaluated the parameters of species relative importance values RIV, i. To test whether coffee regeneration RIV parameters differ between coffee cultivation systems shaded vs unshaded we used generalized linear mixed models GLMMincluding patch size as a random effect to account for the possible confounding effect of patch size in our results. To account for the nestedness of plots within forest patches, we performed simultaneous autoregressive SAR models, assuming spatial autocorrelation among plots and including a second error term in the GLMM.
In SAR models, it is necessary to define a minimum weighted neighborhood structure to fit the spatial structure of the models residuals. We used a neighborhood distance of 0. To evaluate the relationships between coffee basal area and native forest attributes we used six parameters per plot including only native species: We used rarefied species richness to account for the confounding effect of tree density in species richness [ 47 ].
For rarefied richness we used 9 individuals, as this number was found in most plots in both tree and regeneration components S2 Table. We calculated these parameters for the tree component and sapling component separately. To test how coffee is related with native flora, we performed bivariate relationship analysis between coffee basal area and native forest attributes, using GLMMs including patch size as random effect and SARerror models.
The Principle of Causality
We used coffee basal area as a predictor because basal area better reflects species relative biomass, which is a better indicator of plant performance than abundance i. We did not include unshaded patch in the bivariate relationships between coffee and native forest attributes because coffee was absent in most plots BGJF-2, see results section. When necessary, data were square root transformed prior to analysis to meet the assumptions of normality, homoscedasticity, to reduce the effect of outliers, and to account for possible nonlinear relationships between variables.
All analyses were performed using the platform R R-Core-Team, and with the following packages: Additional information on plot structural, diversity, and composition attributes can be found in S2 Table.
Results A total of 4, individuals species and 48 families were sampled in the tree component and 2, individuals species and 40 families in the sapling component S1 Table.
In this case, the third variable might be socioeconomic status -- richer students who have greater resources at their disposal tend to both use computers and do better in their grades.
It's the resources that drives both use and grades, not computer use that causes the change in the grade point average. Patterns of Relationships We have several terms to describe the major different types of patterns one might find in a relationship. First, there is the case of no relationship at all. If you know the values on one variable, you don't know anything about the values on the other.
For instance, I suspect that there is no relationship between the length of the lifeline on your hand and your grade point average. Then, we have the positive relationship.
In a positive relationship, high values on one variable are associated with high values on the other and low values on one are associated with low values on the other. In this example, we assume an idealized positive relationship between years of education and the salary one might expect to be making.CF88 - Art. 5º, XXXVII e LIII (Princípio do Juiz Natural)
On the other hand a negative relationship implies that high values on one variable are associated with low values on the other. This is also sometimes termed an inverse relationship.
Here, we show an idealized negative relationship between a measure of self esteem and a measure of paranoia in psychiatric patients.
