The Expo 2010 Shanghai is taken as an example, and a structural equation model is employed to analyze the dynamic mechanism of trip mode choice behavior and the effectiveness of the transportation management measures at different stages. Based on the difference between the objective-oriented stated preference （SP） survey results and the objectives, together with the feedback from the previous stage survey, some adjustments on the transportation management measures are made in the next stage of the planning process until the objectives are eventually achieved. The results indicate that the adjustments on transportation management measures at different stages can effectively raise the transit share to 88.6%. Nonlocal visitors are inclined to choose nonstop modes of transportation and the companion attributes have the most significant effects on the trip mode choices of visitors. The research method is proved to be an effective way to support the decision making process of transportation management measures during planned special events in the future.展开更多

The end points included patency rates on catheterization laboratory (cath lab) arrival, revascularization results when PCI was performed, complication rates, left ventricular function and restored patency rate following PCI. Results Patency on cath lab arrival was 64% with rt PA (34% TIMI 3,30% TIMI 2), while 31% of placebo (13% TIMI 3, 18% TIMI 2). There was no difference in the restored TIMI 3 rates of IRA between the two groups (85% vs 87%). No difference were observed in stroke or major bleeding. Left ventricular function was similar in both groups (52±9% vs 50±8%), but left ventricular ejection fraction fraction (LVEF) was higher with patent IRA (TIMI 3) on cath lab arrival than that of others (56±12% vs 48±10%).Conclusions Strategy thrombolytic regimens were compatible with subsequent PCI lead to more frequenc early recanalization (before cath lab arrival), which facilitates greater left ventricular function preservation with no augmentation of adverse events.展开更多

METHODS： Between January 2000 and November 2005, 71 patients were operated for the treatment of AMI. The indications for a second-look were low flow state, bowel resection and anastomosis or mesenteric thromboembolectomy performed during the first operation. Regardless of the clinical course of patients, the second-look laparoscopic examination was performed 72 h post-operatively at the bed side in the ICU or operating room. RESULTS： The average time of admission to the hospital after the initation of syrnptoms was 3 d （range, 5 h-9 d）. In 14 patients, laparotomy was performed. In 11 patients, small and/or large bowel necrosis was detected and initial resection and anastomosis were conducted. A low flow state was observed in two patients and superior mesenteric artery thromboembolectomy with small bowel resection was performed in one patient. In 13 patients, a second-look laparoscopic examination revealed normal bowel viability, but in one patient, intestinal necrosis was detected. In two of the patients, a third operation was necessary to correct anastomotic leakage. The overall complication rate was 42.8%, and in-hospital mortality rate was 57.1% （n = 6）. CONCLUSION： Second-look laparoscopy is a minimally invasive, technically simple procedure that is performed for diagnostic as well as therapeutic purposes. The simplicity and ease of this method may encourage wider application to benefit more patients. However, the timing of a second-look procedure is unclear particularly in a patient with anastomosis.展开更多

In contrast to this overall reduction, Planned Parenthood Federation of America abortion providers exhibit a persistent increase in both abortions and their market share percentage of total abortion procedures. For the period 1995-2014, estimated annual and cumulative excess abortions are calculated (Planned Parenthood Abortion Inflation Effect—PPAIE) to indicate the number of abortions which would have been averted if the PP utilization experience had been identical to that of Non-PP abortion providers. PP excess abortions grew steadily each year from 21,000 in 1996 to 258,200 in 2014, 28% of total abortions that year. The cumulative number of abortions added by the PPAIE from 1995-2014 was 3,025,560 or 12.5% of the 24,112,600 performed. Planned Parenthood has had a long-term and accelerating inflationary effect on the incidence and prevalence of abortion in the US.展开更多

文摘Objective:Coronavirus disease 2019(COVID-19)has become an increasingly severe public health emergency.Although traditional Chinese medicine(TCM)has helped to combat COVID-19,public perception of TCM remains controversial.We used the theory of planned behavior(TPB)to identify factors that affect the intention to use TCM.Methods:A cross-sectional web-based survey of 10,824 individuals from the general public was conducted between March 16 and April 2,2020.The participants were recruited using a snowball sampling method.Data were collected using a self-administered questionnaire,based on the TPB.The questionnaire consisted of demographic characteristics and TPB structures.Structural equation modeling was used to identify predictors of intention.Results:The results indicated the model explained 77.5%and 71.9%of intention and attitude variance.Intention to use TCM had the strongest relationship with attitude(P<0.001),followed by past behavior(P<0.001),subjective norms(P<0.001)and perceived behavioral control(P<0.001).Attitudes toward TCM were significantly affected by perceived behavioral control(P<0.001),subjective norms(P<0.001)and cognition of TCM(P<0.001).Conclusion:Attitude is a key factor in determining the intention to use TCM,followed by past behaviors,subjective norms and perceived behavioral control.Our results offer important implications for health policy makers to promote the use of TCM.
文摘Objectives:To examine the efficacy of an intervention based on the theory of planned behavior(TPB)in improving breastfeeding behavior among women with cesarean sections(C-sections).Methods:This research was a randomized controlled trial.Women with planned elective C-sections were recruited to participate in a randomized controlled trial between June and September 2020.One hundred thirty-two women were divided randomly into the intervention(n=66)and control group(n=66)by systematic random sampling.In the intervention group,an intervention project was implemented after Keywords:Breastfeeding Cesarean section Intervention studies Theory of planned behavior the C-section to establish positive breastfeeding attitudes,cultivate supportive subjective norms,enhance perceived behavioral control,and strengthen breastfeeding intention to change behaviors.Those in the control group received routine pre-and post-delivery care.Exclusive breastfeeding rate and breast problem were collected at 5 days,2 weeks,and 1 month after C-section.The modified Breastfeeding Attrition Prediction Tool(BAPT)on the first day in the hospital,two weeks,and one month after C-section and Numerical Rating Scale(NRS)24 h postoperatively were used to compare the intervention effect between the two groups.Results:After the intervention,the intervention group had significantly higher exclusive breastfeeding rates than the control group at five days(86.4%vs.60.6%),two weeks(77.3%vs.57.6%),and one month(74.2%vs.50.0%)after the C-section.Besides,the intervention group was less likely to have sore nipples at five days(6.1%vs.18.2%in the control group,P<0.05)and two weeks(9.1%vs.12.1%in the control group,P<0.05).After two weeks of intervention,attitude scores(90.64±8.31 vs.87.20±8.15,P<0.05),subjective norm scores(88.07±24.65 vs.79.42±19.47,P<0.05)and behavior control scores in the intervention group were significantly higher than those in the control group.After one month of intervention,attitude scores(90.34±10.35 vs.84.22±10.51,P<0.05)and behavior control scores(43.13±5.02 vs.39.15±4.69,P<0.05)in the intervention group were significantly higher than those in the control group,which resulted in the higher breastfeeding intention in the intervention group.Conclusion:This study indicated that the TPB-based interventions effectively improved women's breastfeeding behaviors after C-sections.

文摘As a cultural concept refl ecting the relationship between humans and forests,forest culture plays an active role in sustainable forest management.Forest parks provide a wide range of ecosystem services essential for the sustainable development of society,and the relationships between forest culture,green construction and management of forest parks have practical signifi cance.This study aimed to understand the interaction and process of forest culture infl uencing green construction and management in forest parks with the models Knowledge-Attitude-Practice(KAP)and Theory of Planned Behavior(TPB)by proposing a theoretical model.Four hypotheses were tested using data collected from 193 forest park employees in Heilongjiang Province,China.Our results show that forest culture had a signifi cant infl uence on green construction and forest management.In addition,subjective norm and perceived behavioral control directly impacted behavior in green construction and management of the forest park,whereas attitude did not have an impact.Subjective norm had a direct eff ect on attitude.Results between constructs show that forest culture had an indirect eff ect on planning and construction,and on ecological and economic management.Consequently,it supported three of four hypotheses within the proposed model in determining the infl uence of forest culture on green construction and management.
文摘This paper aims to propose a modeling framework for subway operation and maintenance system (SOMS), which analyzes the train condition data based on both train sensor network data and basis train maintenance plan. The system is formulated into five function modules, and the research problem is to determine one auxiliary maintains plan, including the time allocation and frequency of maintenance. The case of Guangzhou metro is conducted to illustrate the applicability of SOMS, and the results reveal a number of interesting insights into subway maintenance system, i.e., the worksheet can reduce duplication of redundant maintenance work, the repair cost, and the damage caused by frequent disassembly.
文摘The rate and number of induced abortions in the US has declined steadily for nearly three decades. In contrast to this overall reduction, Planned Parenthood Federation of America abortion providers exhibit a persistent increase in both abortions and their market share percentage of total abortion procedures. For the period 1995-2014, estimated annual and cumulative excess abortions are calculated (Planned Parenthood Abortion Inflation Effect—PPAIE) to indicate the number of abortions which would have been averted if the PP utilization experience had been identical to that of Non-PP abortion providers. PP excess abortions grew steadily each year from 21,000 in 1996 to 258,200 in 2014, 28% of total abortions that year. The cumulative number of abortions added by the PPAIE from 1995-2014 was 3,025,560 or 12.5% of the 24,112,600 performed. Planned Parenthood has had a long-term and accelerating inflationary effect on the incidence and prevalence of abortion in the US.

文摘In the context of rural revitalization,people are re-examining the issue of creating the role of teachers as“new rural sages”.However,most of previous studies ignored the school organizational change in the process of reform.The planned happenstance suggests that teachers should maintain a positive mindset about the eventualities in their careers.Based on the organizational change theory,this paper gave some advice to help teachers in playing a role of new rural sages:①rooting in local culture and enhancing teachers’sense of belonging,②providing compensation for teachers in a targeted way,and③providing a comprehensive and objective evaluation mechanism for ensuring teachers’participation in social governance.
