RESUMO

PURPOSE: This study examined a serial mediation model testing the effects of STS on turnover intention through executive leaders' use of transformational leadership as perceived by child welfare workers and then organizational commitment while controlling for age, gender, and social work degrees. METHOD: Survey data were collected from 264 child welfare workers at one Midwestern state. RESULTS: The results supported the serial mediation model, corroborated by the finding that the impact of STS on turnover intention has disappeared as a result of transformational leadership and organizational commitment between the two variables. DISCUSSION: The findings of the study provide practical implications for training transformational leadership styles to leaders training at the middle manager and executive leadership levels in child welfare agencies.

RESUMO

PURPOSE: A coalition model is often used to serve victims of human trafficking but little is known about whether the model is adequately meeting the needs of the victims. The purpose of this study was to examine anti-human trafficking collaboration model in terms of its impact and the collaborative experience, including challenges and lessons learned from the service providers' perspective. METHOD: Mixed methods study was conducted to evaluate the impact of a citywide anti-trafficking coalition model from the providers' perspectives. Web-based survey was administered with service providers (n = 32) and focus groups were conducted with Core Group members (n = 10). RESULTS: Providers reported the coalition model has made important impacts in the community by increasing coordination among the key agencies, law enforcement, and service providers and improving quality of service provision. Providers identified the improved and expanded partnerships among coalition members as the key contributing factor to the success of the coalition model. DISCUSSION: Several key strategies were suggested to improve the coalition model: improved referral tracking, key partner and protocol development, and information sharing.

RESUMO

BACKGROUND: This study evaluated the accuracy of blow out fracture reduction using 3D-printed rapid prototyping (RP) skull modeling. PATIENTS AND METHODS: Retrospective review was performed for 82 patients who underwent post-traumatic orbital wall fracture reduction between 2012 and 2014. Patients were divided into two groups according to the use of 3D-printed RP skull model reproduced by mirroring technique, onto which a titanium mesh was anatomically molded. Using computed tomographic scans, the areas of pre- and post-operative orbital wall defect, the layout angles of the titanium mesh, and the gap lengths between the implant and fracture margin were compared between the two groups. RESULTS: Of the 82 patients identified, 46 and 36 were diagnosed with medial and inferior orbital wall fractures, respectively. Bone defect area of the RP group was significantly reduced in comparison with that of the conventional group (8.03 ± 3.5% versus 18.7 ± 15.41% for medial wall fractures, 7.14 ± 5.74% versus 12.8 ± 4.92% for inferior wall fractures, respectively, p < 0.01). Satisfactory results were achieved regarding the layout angles and the gap lengths, presenting significantly reduced values in the RP group compared to that in the conventional group (p < 0.01). CONCLUSIONS: More accurate restoration of traumatic orbital wall fractures can be achieved using patient-specific 3D-printed RP skull models.

RESUMO

OBJECTIVE: To explore the relationship between α-synuclein pathology and mitochondrial respiratory chain protein levels within single substantia nigra neurons. DESIGN: We examined α-synuclein and mitochondrial protein expression in substantia nigra neurons of 8 patients with dementia with Lewy bodies, 5 patients with Parkinson disease, and 8 control subjects. Protein expression was determined using immunocytochemistry followed by densometric analysis. PATIENTS: We examined single substantia nigra neurons from 5 patients with idiopathic Parkinson disease (mean age, 81.2 years), 8 patients with dementia with Lewy bodies (mean age, 75 years), and 8 neurologically and pathologically normal control subjects (mean age, 74.5 years). The control cases showed minimal Lewy body pathology and cell loss. Patients with dementia with Lewy bodies and idiopathic Parkinson disease fulfilled the clinical and neuropathologic criteria for these diseases. RESULTS: Our results showed that mitochondrial density is the same in nigral neurons with and without α-synuclein pathology. However, there are significantly higher levels of the respiratory chain subunits in neurons containing α-synuclein pathology. CONCLUSIONS: The finding of increased levels of respiratory chain complex subunits within neurons containing α-synuclein does not support a direct association between mitochondrial respiratory chain dysfunction and the formation of α-synuclein pathology.
