诺舒阻抗与宫腔镜两种子宫内膜切除术的比较研究

探讨诺舒阻抗子宫内膜切除术在月经过多患者中的临床应用及优越性。将我院2010年1月至2014年5月行诺舒阻抗子宫内膜切除术的57例患者,纳为治疗组。同期宫腔镜单极子宫内膜切除术的45例患者,纳为对照组,比较两组患者术中情况及术后随访各项指标。发现治疗组的手术时间、术中出血量、膨宫液吸收量、电解质紊乱、术后阴道出血时间、阴道排液时间、宫腔积血、宫腔粘连、药物辅助治疗、再次手术（全子宫切除术）均低于对照组,组间对比有统计学意义（P〈0．05）。诺舒阻抗子宫内膜切除术具有学习曲线短、手术易掌握、操作安全、疗效肯定的优点,是目前子宫内膜切除术的首选方法。     

Optimal or Typical Performance? The Impact of Instructional Set on the Behavioral Assessment of Parent-Child Interactions

The behavioral assessment of parent-child interactions is an important component of treatment planning and evaluation in many evidence-based parent training programs. However, numerous factors unrelated to the parent-child interaction may add error to the assessment. This study investigated the impact of task instructions on parents’ behaviors during the analogue parent-child interaction observation, the Dyadic Parent-Child Interaction Coding System (DPICS). Forty-eight mother-child dyads were randomly assigned to one of two conditions that differed on level of specificity of instructions. Significant differences were observed between groups, with parents who received specific instructions using more praises during the DPICS tasks. Specific instructions may shift parents’ behaviors toward optimal, rather than typical, interaction patterns and should be considered in the context of the assessment goals.     

Equivalent and effective strains during severe plastic deformation (SPD)

ABSTRACT

This paper considers the characteristics of severe plastic deformation (SPD) to estimate its efficacy and to compare different processing techniques. In contrast to effective strains by von Mises and Hencky, the rotation component of the strain rate is included in the analysis as a mode of deformation, which ranges from simple shear to pure shear. Distortions of material elements during a uniform plane plastic flow are calculated using a kinematic approach. For the fixed deformation mode, the current state is defined by the accumulated shears that are identical to the von Mises effective shear strains. In specific cases of pure shear and simple shear, the accumulated shears match the specific distortions of round or square elements prescribed by Hencky or von Mises approach, respectively. The mode of deformation is important to the structural effects of SPD. In general, two separated characteristics, accumulated shear and the coefficient of deformation mode, are necessary to describe strains during SPD.     

Using a Self-Management Intervention to Increase Compliance in Children With ASD

This two-study series examined the effectiveness of self-management in increase compliance with parental requests. Three boys diagnosed with Autism Spectrum Disorder and their parents participated. The intervention involved self-monitoring combined with parent-delivered reinforcement. A multiple baseline design was used. The intervention was successful in increasing rates of compliance and reducing problem behavior in training and generalization settings with each participant. Social validity was high and treatment integrity data indicated that the intervention could be readily implemented by parents. Study 2 also provided evidence of a strong treatment effect for the self-management beyond a small effect for effective instructional delivery.

Interdisciplinary Knowledge Translation: Lessons Learned from a Mental Health: Fire Service Collaboration

Collaborative approaches are being increasingly advocated for addressing a variety of health, mental health and social needs for children, youth and families. Factors important for effective knowledge translation of collaborative approaches of service delivery across disciplines, however, have not been rigorously examined. TAPP-C: The Arson Prevention Program for Children is an intervention program for child and adolescent firesetters provided collaboratively by fire service and mental health professionals. The present study examined the adopter, innovation, and dissemination characteristics associated with TAPP-C implementation, protocol adherence and extent of collaboration by 241 community-based fire service professionals from communities across Ontario. Results revealed that dissemination factors are particularly important for understanding program implementation, adherence and cross-discipline collaboration. Moreover, the findings of this study show significant benefits to both within discipline (intra-disciplinary) and across discipline (interdisciplinary) knowledge translation strategies.     

The Effects of Using Response Cards on Student Participation, Academic Achievement, and On-Task Behavior During Whole-Class, Math Instruction

This study evaluated the effects of using response cards during whole-group math instruction in a fourth-grade classroom, using an ABA research design. During both A and B conditions the classroom teacher conducted her math lessons as planned. However during the A conditions, hand-raising (HR) was in effect. That is, when the teacher asked a question she instructed the students to raise their hands and after each question she called on one student whose hand was raised. During the B condition, response cards (RC) were in effect. Whenever she asked a question, the teacher instructed the entire class to write their answers on individual response cards. After each question, the teacher instructed the entire class to hold up their RC. Data were collected on five students who represented the class range in general level of participation, academic skills, and on-task behavior. Results indicated that student participation, specifically the number of student-initiated opportunities to respond and the number of student responses were higher when using RC than when HR was in effect. Students scored higher on the weekly math quiz after the RC condition than after the HR conditions. The percentage of intervals that students were on-task also was higher when RC were used.
