Correspondingly, the local government conducted an exploration of the organization and management mode in the field of planning and construction. The effective experiences have been accumulated, including working out a full coverage planning,taking the leading part in the urban-rural planning,and exercising whole space control over the disaster area. An innovation management mode named as "Five Generals Pattern"was implemented in the construction projects. In view that the rural housing reconstruction was a weak link, a new approach to improving the construction management was investigated,by means of strengthening on-site supervision,establishing a technical platform,and bolstering public participation.展开更多

The relationship between the volume of irradiated small bowel(VSB) and acute bowel toxicity was determined. A total of 97 cases of rectal cancer were retrospectively randomized to receive radiotherapy with the designated treatment positions and radiation plans. Among 64 patients in the supine position, 32 patients were given three-dimensional conformal radiotherapy(3DCR) and 32 patients were subjected to intensity-modulated radiation therapy(IMRT) respectively. The rest 33 patients were treated with 3DCRT in the prone position with a belly board. The VSB was calculated for doses from 5 to 45 Gy at an interval of 5 Gy. With prescription dose in planned target volume(PTV) of 50 Gy, the dose distribution, conformal index for PTV(CIPTV), dose-volume histogram(DVH) of OARs, the correlation of VSB and the acute toxicity were compared. The results were shown as follows:(1) Among the 3 methods, there were no differences in PTV's converge including V95 and D95;(2) For IMRT under a supine position, CIPTV was closest to 1, the mean dose of small bowel decreased(P〈0.05), and the mean VSB from V30 to V45 significantly decreased(P〈0.05).(3) For 3DCRT with a belly board under a prone position, the mean dose and the mean VSB from 40 to 45 Gy were less than those for 3DCRT under a supine position(P〈0.05);(4) Mean proportion of VSB was significantly greater in the patients experiencing diarrhea grade 2-4 than in those with diarrhea grade 0-1 at dose levels from V30 to V45(P〈0.05). It was concluded that for the radiotherapy of rectal cancer, IMRT technique might decrease the high-dose VSB to reduce the risk of acute injury. 3DCRT with a belly board under a prone position is superior to 3DCRT under a supine position, which could be a second choice for radiation of rectal cancer.展开更多

Despite the high nutritional need of this element by the plants, it is not a constituent of any terrestrial rock. To avoid high production costs of N, there is an increasing interest in the use of organic fertilizers in Brazil, including the use of humic substances (HS). In this work we evaluated the chelating properties of HS, when used together with a source of N. The nitrogen source used in this experiment was the ammonia. We checked the optimum conditions for interaction between the HS and ammonia such as: the ratio of reaction of each compound;minimum incorporation time between these compounds and the amount of ammonia that can be adsorbed by HS (income). The best ratio of ammonia/HS was 1/50 (v/v). Higher amounts of ammonia added to 50 mL of HS caused a greater loss of N. We also concluded that the application of ammonia/HS in the soil can be made immediately after their mixing, without the need of higher contact time between these substances in order to have the adsorption. No loss of ammonia was detected after 72 hours of its application together with HS. Finally, by using a factorial design, the best working area was found by settling the time of incorporation and volatilization in 24 h, and the volumes of HS and NH3 in 100 and 2 mL, respectively.展开更多

Different research project outputs (field survey and workshop reports) produced during the implementation of GFCS APA are reviewed to assess the contribution of GFCS APA programme in the establishment and implementation of NAP process in Tanzania. It is found that the implementation of GFCS-APA programme in Tanzania has improved the availability, accessibility, and applicability of climate information to different stakeholders. This has in turn attributed to significant use of climate information in planning and decision making in target sectors: agriculture and food security, disaster risk reduction, energy, health and water resource management. This has increased the adaptation capacity of vulnerable communities from the impacts of climate variability and change. Furthermore, it is evident that the aims and objectives of establishments of NAP process in Tanzania have been addressed through implementation of GFCS APA Programme. Moreover, since the GFCS APA in Tanzania is implemented within its five pillars namely: observation and monitoring, research, modeling and prediction, climate information systems, user interface platform and capacity development. The achievement made in each pillar contributed in enhancement of resilience of vulnerable communities to climate variability and change hence addressing the aims and objectives of NAP process in Tanzania. Therefore, it is recommended that achievements of GFCS APA Programme in Tanzania to be used as a guide to the development and implementations of the NAP process in Tanzania.展开更多

Furthermore,soil carbon density decreased generally with the depth,as well as carbon content. In the whole soil profile,the range of carbon density in these five forests was from 4. 79 kg / m2 to 5. 62 kg / m2. However,60% carbon was concentrated in40 cm depth of soil. The calculated result of soil organic carbon reserve was as follows: Cupressus lusitanica( 50. 264 t / hm2),hackberry( 47. 859 t/hm2),Populus L.( 53. 216 t/hm2),Red bayberry( 49. 581 t/hm2),Amygdalus persica L.( 58. 202 t/hm2),with the average storage of 51. 824 t / hm2,lower than the national average level,so,people should pay attention to the artificial forest tending and management.According to the above analysis,this paper concluded that the afforestation was the effective measure for increasing the soil organic carbon accumulation,and the effects of planting the indigenous tree species Cupressus lusitanica and Amygdalus persica L. were best.展开更多

In Study 1 (N = 550), we tested the HAPA’s stages in terms of discontinuity patterns in the variables predicting goal setting for organ donation. As expected, multigroup structural equation modeling revealed discontinuity patterns in terms of different prediction patterns. In Study 2 (N = 389), the efficacy of a planning intervention that aimed to foster the translation of goals into behavior was tested: participants who received the intervention were more likely to order a donor card than those who did not. Contrary to the HAPA’s predictions, within the intenders group the planning intervention did not stimulate behavior more frequently than in the control condition. In general, the stage-specific planning intervention is of practical importance, as it shows that brief and relatively inexpensive communication can enhance organ donation behavior.展开更多

The purposes of this study are to 1) assess geometric and dosimetric uncertainties due to inter-observer contour variabilities and 2) evaluate the effectiveness of geometric indicators to predict target dosimetry in prostate radiotherapy. </span><b><span style="font-family:Verdana;">Methods:</span></b><span style="font-family:Verdana;"> Twenty prostate patients were selected for this retrospective study. Five experienced clinicians created unique structure sets containing prostate, seminal vesicles, bladder, and rectum for each patient. A fully automated script and knowledge-based planning routine were utilized to create standardized and unbiased plans that could be used to evaluate changes in isodose distributions due to inter-observer variability in structure segmentation. Plans were created on a “gold-standard” structure set, as well as on each of the user-defined structure sets. </span><b><span style="font-family:Verdana;">Results:</span></b><span style="font-family:Verdana;"> Inter-observer variability of contours during structure segmentation was very low for clearly defined organs such as the bladder but increased for organs without well-defined borders (prostate, seminal vesicles, and rectum). For plans generated with the user-defined structure sets, strong/moderate correlations were observed between the geometric indicators for target structure agreement and target coverage for both low-risk and intermediate-risk patient groups, while OAR indicators showed no correlation to final dosimetry. </span><b><span style="font-family:Verdana;">Conclusions:</span></b><span style="font-family:Verdana;"> Target delineation is crucial in order to maintain adequate dosimetric coverage regardless of the associated inter-observer uncertainties in OAR contours that had a limited impact upon final dosimetry.</span></span>展开更多

The present study aims to find the effect of cultural orientatiotr---like individualism or collectivism on a person's organizational citizenship behavior (OCB) There are many studies related to collectivism and organization citizenship behavior as well as organization commitment and OCB. But most of these studies were done in a western context and is done years back. The present generation of UAE having undergone studies in management which is highly dominated by western philosophies and due to their interaction with diverse nationalities have evolved in their behavior. At this point it is necessary to investigate whether there is any shift in their behavior pattems based on collectivism. Career commitment has grown among UAE nationals in recent years due to high level of commitment from the government towards education and employment. Since OCB is more of an altruistic tendency within an individual, the study looks into the cultural difference within an individual like individualism or collectivism and its relationship with a person's OCB level among the employees in UAE. Career commitment is taken as a another variable. The study has made some interesting findings which show a shift from the previous studies that show a direct relationship using correlation analysis, between collectivism and organization citizenship behavior. The study found that there is no relationship between individualism or collectivism and organization citizenship behavior, but there is some relationship between career commitment and organization citizenship behavior factor loyal boosterism.展开更多

文摘This article assesses the contribution of the Global Framework for Climate Services Adaptation Programme in Africa (GFCS APA) in the National Adaptation Plan (NAP) process for Tanzania. Different research project outputs (field survey and workshop reports) produced during the implementation of GFCS APA are reviewed to assess the contribution of GFCS APA programme in the establishment and implementation of NAP process in Tanzania. It is found that the implementation of GFCS-APA programme in Tanzania has improved the availability, accessibility, and applicability of climate information to different stakeholders. This has in turn attributed to significant use of climate information in planning and decision making in target sectors: agriculture and food security, disaster risk reduction, energy, health and water resource management. This has increased the adaptation capacity of vulnerable communities from the impacts of climate variability and change. Furthermore, it is evident that the aims and objectives of establishments of NAP process in Tanzania have been addressed through implementation of GFCS APA Programme. Moreover, since the GFCS APA in Tanzania is implemented within its five pillars namely: observation and monitoring, research, modeling and prediction, climate information systems, user interface platform and capacity development. The achievement made in each pillar contributed in enhancement of resilience of vulnerable communities to climate variability and change hence addressing the aims and objectives of NAP process in Tanzania. Therefore, it is recommended that achievements of GFCS APA Programme in Tanzania to be used as a guide to the development and implementations of the NAP process in Tanzania.

文摘Based on the field data and laboratory analysis,we studied the soil organic carbon storage and vertical distribution features about five kinds of plantations in Xuyi,and the results showed that soil carbon density in the five forest types changed greatly,with a range of 0. 8-3. 04 kg / m2 for five soil layers. Furthermore,soil carbon density decreased generally with the depth,as well as carbon content. In the whole soil profile,the range of carbon density in these five forests was from 4. 79 kg / m2 to 5. 62 kg / m2. However,60% carbon was concentrated in40 cm depth of soil. The calculated result of soil organic carbon reserve was as follows: Cupressus lusitanica( 50. 264 t / hm2),hackberry( 47. 859 t/hm2),Populus L.( 53. 216 t/hm2),Red bayberry( 49. 581 t/hm2),Amygdalus persica L.( 58. 202 t/hm2),with the average storage of 51. 824 t / hm2,lower than the national average level,so,people should pay attention to the artificial forest tending and management.According to the above analysis,this paper concluded that the afforestation was the effective measure for increasing the soil organic carbon accumulation,and the effects of planting the indigenous tree species Cupressus lusitanica and Amygdalus persica L. were best.

文摘Using the Health Action Process Approach (HAPA) as a theoretical backdrop, the aim of this research, which consists of two studies, was to understand the process of goal setting and deciding to sign an organ donor card. In Study 1 (N = 550), we tested the HAPA’s stages in terms of discontinuity patterns in the variables predicting goal setting for organ donation. As expected, multigroup structural equation modeling revealed discontinuity patterns in terms of different prediction patterns. In Study 2 (N = 389), the efficacy of a planning intervention that aimed to foster the translation of goals into behavior was tested: participants who received the intervention were more likely to order a donor card than those who did not. Contrary to the HAPA’s predictions, within the intenders group the planning intervention did not stimulate behavior more frequently than in the control condition. In general, the stage-specific planning intervention is of practical importance, as it shows that brief and relatively inexpensive communication can enhance organ donation behavior.
文摘<strong>Purpose:</strong><span style="font-family:;" "=""><span style="font-family:Verdana;"> Radiotherapy is a widely accepted standard of care for early-stage prostate cancer, and it is believed that the plan quality and treatment outcome are associated with contour accuracy of both the target and organs-at-risk (OAR). The purposes of this study are to 1) assess geometric and dosimetric uncertainties due to inter-observer contour variabilities and 2) evaluate the effectiveness of geometric indicators to predict target dosimetry in prostate radiotherapy. </span><b><span style="font-family:Verdana;">Methods:</span></b><span style="font-family:Verdana;"> Twenty prostate patients were selected for this retrospective study. Five experienced clinicians created unique structure sets containing prostate, seminal vesicles, bladder, and rectum for each patient. A fully automated script and knowledge-based planning routine were utilized to create standardized and unbiased plans that could be used to evaluate changes in isodose distributions due to inter-observer variability in structure segmentation. Plans were created on a “gold-standard” structure set, as well as on each of the user-defined structure sets. </span><b><span style="font-family:Verdana;">Results:</span></b><span style="font-family:Verdana;"> Inter-observer variability of contours during structure segmentation was very low for clearly defined organs such as the bladder but increased for organs without well-defined borders (prostate, seminal vesicles, and rectum). For plans generated with the user-defined structure sets, strong/moderate correlations were observed between the geometric indicators for target structure agreement and target coverage for both low-risk and intermediate-risk patient groups, while OAR indicators showed no correlation to final dosimetry. </span><b><span style="font-family:Verdana;">Conclusions:</span></b><span style="font-family:Verdana;"> Target delineation is crucial in order to maintain adequate dosimetric coverage regardless of the associated inter-observer uncertainties in OAR contours that had a limited impact upon final dosimetry.</span></span>
文摘UAE is considered as collectivistic as per many major studies on culture. The present study aims to find the effect of cultural orientatiotr---like individualism or collectivism on a person's organizational citizenship behavior (OCB) There are many studies related to collectivism and organization citizenship behavior as well as organization commitment and OCB. But most of these studies were done in a western context and is done years back. The present generation of UAE having undergone studies in management which is highly dominated by western philosophies and due to their interaction with diverse nationalities have evolved in their behavior. At this point it is necessary to investigate whether there is any shift in their behavior pattems based on collectivism. Career commitment has grown among UAE nationals in recent years due to high level of commitment from the government towards education and employment. Since OCB is more of an altruistic tendency within an individual, the study looks into the cultural difference within an individual like individualism or collectivism and its relationship with a person's OCB level among the employees in UAE. Career commitment is taken as a another variable. The study has made some interesting findings which show a shift from the previous studies that show a direct relationship using correlation analysis, between collectivism and organization citizenship behavior. The study found that there is no relationship between individualism or collectivism and organization citizenship behavior, but there is some relationship between career commitment and organization citizenship behavior factor loyal boosterism.
