### Cultural Differences by Demographic Variables
#### 3.2.3 Differences by Contractual Relationship (Own Staff vs. Contractor)  
Considering NPP and NPC together, results show homogeneity of scores in all three OCI types of culture between own staff and contractors (Table 8; Figure 8). There is only a small difference in the \"Affiliative\" style of the \"Constructive\" cluster (own staff M = 3.54; contractor M = 3.73; \(\delta=-0.21\)) (Table 8; Figure 9). Figure 6: OCI organizational cultures averages by work location. Figure 7: OCI styles averages by work location. \begin{table}

Table 8: Descriptive statistics of the OCI organizational cultures and styles by contractual relationship. There are no differences in any of the three OCI organizational cultures by contractual relationship in NPP, with the only exception of a small one in the \"Competitive\" style in which contractor personnel score higher than own staff (own staff M = 1.98; contractor M = 2.16; \(\delta\) = \(-\)0.21), (NPP; Table 8). In NPC, contractor personnel score higher than own staff in the \"Constructive\" organizational culture (own staff M = 3.13; contractor M = 3.53; \(\delta\) = \(-\)0.57). The norms with the highest differences are \"Humanistic-Encouraging\" (\(\delta\) = 0.62), \"Affiliative\" (\(\delta\) = 0.54) and\" Self-Actualizing\" (\(\delta\) = 0.53). Similarly, contractor personnel scores lower in the \"Passive/Defensive\" organizational culture (own staff M = 3.05; contractor M = 2.92; \(\delta\) = 0.28).
