The national cooperation variable (cooperNat) is introduced as a binary variable showing whether a firm has signed, during the 2005 2007 period, any cooperation contracts with other companies in the same field, with consumers, with equipment and software suppliers, with competitors, with research and counseling firms and with universities situated in Tunisia.
Resource supply may also affect the benefits of cooperation: variable benefits of biofilm dwelling across the resource supply gradient could have altered the strength of selection upon SM for inhabiting the biofilm relative to selection for leaving the biofilm entirely.
We began the logistic regression analysis with a manual backward stepwise regression of the cooperation variables on the risk perception variables and a set of demographic control variables, and then built final models with the variables that were relevant to the hypothesis.
Table 2 contains descriptions of the cooperation response variables and risk perception explanatory variables.> To analyze the interview transcripts we followed a standard protocol of qualitative analysis (Patton 2002).
It is worth noting that in the case of cooperation, the variables and which represent the respective cooperating preferences for the source and the relay are subjected to the following constraints: (8).
The fourth component (PC4), namely trust in other people's cooperation, comprises variables defining trust in other farmers' willingness to take part in collective action aimed at biomass production.
Moreover, extensive theoretical work illustrates how both pathogen and host population structure mediate selection for virulence (e.g. 42); if virulence is determined by cooperation, these variables will by necessity also affect pathogen sociality.
For that purpose, a network of seven BSs is simulated, where a single cooperation cluster of variable size, with M∈{3,…,7}, is assumed.
These preconditions include longevity, extended adolescence, communication skills, cooperation, and a variable habitat [29].
Hospitals are divided into two groups on both variables: 50% of the hospitals with the highest scores in group 1, 50% with the lowest scores in group 2.> As we can see from Table 6, hospitals that have both high total hospital efficiency and high departmental efficiency also have the highest score on variable cooperation.
The coefficient variables cooperation coefficient, spend coefficient and cost exponential impose significant influence on the diffusion of cooperation, and the signs are not surprising.
