An international comparison using a diagnostic testing model: Turkish students’ profile of mathematical skills on TIMSS-R 总被引：2，自引：0，他引：2
This study illustrates how a diagnostic testing model can be used to make detailed comparisons between student populations
participating in international assessments. The performance of Turkish students on the TIMSS-R mathematics test was reanalyzed
with a diagnostic testing model called the Rule Space Model. First, mathematical and cognitive skills (‘attributes’) measured
by the test were determined. One hundred sixty-two items were coded in terms of their attribute involvement, creating an incidence
matrix—the Q-matrix. Using the Q-matrix and the student response data, each student’s attribute mastery profile was determined.
Mean attribute mastery levels of Turkish students were computed and compared to those of their American peers. It was shown
that Turkish students were weak in algebra and probability/statistics. They also demonstrated poor profiles in skills such
as applying rules in algebra, approximation/estimation, solving open-ended problems, recognizing patterns and relationships,
and quantitative reading.

This study investigates the antecedents and consequences of team learning, which is composed of information acquisition, dissemination, and implementation, in information technology (IT) implementation projects. By investigating 129 IT implementation project teams, we found that (1) information acquisition and information dissemination have a positive impact on project outcomes, such as speed-to-users, lower implementation cost, and operational effectiveness, and (2) team behavior and enabler variables, such as teamwork, team communication, interpersonal trust between team members, team commitment, and senior manager support, positively influence team learning. We also found that team anxiety moderates the relationship between team learning and project outcomes. 相似文献

Introduction:
Serum blood collection tubes with separator gel are widely used by many laboratories for chemistry analyses. We describe a case of a primary blood collection tube filled with blood sample and a floating separator gel.Materials and methods:
The blood sample was collected from a 51 years old female in intensive care unit with the diagnosis of pneumonia into a BD Vacutainer SST tube (Becton Dickinson, NJ, USA) containing serum separator gel and conveyed to the core laboratory of Marmara University Hospital within 30 minutes from collection. Sample was immediately centrifuged at room temperature at 1500 × g for 10 minutes.Results:
The analyses revealed a highly increased total protein concentration of 145 g/L (reference interval 64–83 g/L). The nephelometric analyses showed an elevated serum IgG concentration of 108 g/L (reference interval 6.5–16 g/L) and IgG lambda monoclonal band was determined by serum immunofixation electrophoresis.Conclusion:
Limitation of the separator gel tubes in patients with a high plasma density and its possible effects on test results and laboratory costs should be remembered. The clinical diagnosis stated in the information system should also reveal known comorbid conditions besides the apparent admission reason. This information would avoid resampling, additional testing, and communication efforts with the clinicians. 相似文献5.
We tested three theories (adult attachment, autonomy/relatedness, and gender roles) to understand relationship satisfaction among 150 British and 170 Turkish adults, all involved in romantic relationships. Avoidance, relatedness, autonomy–relatedness, and masculinity mediated the relationship between culture and romantic relationship satisfaction. Additionally, as anticipated, Turkish participants scored lower on relationship satisfaction and autonomy whereas British participants scored lower on avoidance and relatedness. Contrary to expectation, gender role differences (differences between masculinity and femininity) in the United Kingdom were not significantly smaller than in Turkey. It is concluded that adult attachment provides a useful framework for understanding country-level differences. 相似文献

Objective: This prospective randomized clinical trial was conducted to evaluate the necessity of drainage after total thyroidectomy or lobectomy for benign thyroidal disorders. Methods: A total of 116 patients who underwent total thyroidectomy or lobectomy for benign thyroidal disorders were randomly allocated to be drained or not. Operative and postoperative outcomes including operating time, postoperative pain assessed by visual analogue scale (VAS), total amount of intramuscular analgesic administration, hospital stay, complications, necessity for re-operation and satisfaction of patients were all assessed. Results: The mean operating time was similar between two groups (the drained and non-drained groups). The mean VAS score was found to be significantly low in the non-drained group patients in postoperative day (POD) 0 and POD 1. The mean amount of intramuscular analgesic requirement was significantly less in the non-drained group. One case of hematoma, two cases of seroma and three cases of transient hypoparathyroidism occurred in the non-drained group, whereas one case of hematoma, two cases of seroma, two cases of wound infections and two cases of transient hypoparathyroidism occurred in the drained group. No patient needed re-operation for any complication. The mean hospital stay was significantly shorter and the satisfaction of patients was superior in the non-drained group. Conclusion: These findings suggest that postoperative complications cannot be prevented by using drains after total thyroidectomy or lobectomy for benign thyroid disorders. Furthermore, the use of drains may increase postoperative pain and the analgesic requirement, and prolong the hospital stay. In the light of these findings, the routine use of drains might not be necessary after thyroid surgery for benign disorders. 相似文献

This study examined the role of adolescent perceptions of parental behavior and disrupted parenting in the continuity of antisocial behavior across generations. Participants included 430 adolescents and their biological parents assessed during the period from the 9th to 12th grades (9th grade age in years: M=15.09, SD=0.43). Structural equation modeling provided support for the mediating role of adolescent perceptions and disrupted parenting in the familial transmission of antisocial behavior. Furthermore, the results were consistent across parent and adolescent gender. The findings extend previous research by suggesting a significant role for adolescent perceptions of parents' activities in the development and growth of antisocial behavior. Results also support significant stability in antisocial tendencies over the course of adolescence. 相似文献
