There has been increased awareness of child maltreatment in Saudi Arabia recently. This study assessed the readiness for implementing large-scale evidence-based child maltreatment prevention programs in Saudi Arabia. Key informants, who were key decision makers and senior managers in the field of child maltreatment, were invited to participate in the study. A multidimensional tool, developed by WHO and collaborators from several middle and low income countries, was used to assess 10 dimensions of readiness. A group of experts also gave an objective assessment of the 10 dimensions and key informants’ and experts’ scores were compared. On a scale of 100, the key informants gave a readiness score of 43% for Saudi Arabia to implement large-scale, evidence-based CM prevention programs, and experts gave an overall readiness score of 40%. Both the key informants and experts agreed that 4 of the dimensions (attitudes toward child maltreatment prevention, institutional links and resources, material resources, and human and technical resources) had low readiness scores (<5) each and three dimensions (knowledge of child maltreatment prevention, scientific data on child maltreatment prevention, and will to address child maltreatment problem) had high readiness scores (≥5) each. There was significant disagreement between key informants and experts on the remaining 3 dimensions. Overall, Saudi Arabia has a moderate/fair readiness to implement large-scale child maltreatment prevention programs. Capacity building; strengthening of material resources; and improving institutional links, collaborations, and attitudes toward the child maltreatment problem are required to improve the country's readiness to implement such programs. 相似文献

Literacy education through the LIFE Initiative and follow-up of CONFINTEA VI in the Maghreb ?C Illiteracy is seriously compromising the economic and social development of the Maghreb countries. In Morocco and Mauritania, for instance, national strategies and literacy programmes have been implemented. These efforts ought to be assessed so that lessons can be learned from them and the contribution of the national and international initiatives implemented in recent years can be evaluated. The Sixth International Conference on Adult Education provided an opportunity to launch a Maghreb-wide literacy cooperation process. Drawing on the experience of two high-priority countries (Morocco and Mauritania), the countries of the Maghreb created a mechanism for ongoing exchange within the framework of the Forum on Literacy for the Maghreb Region. The second meeting of this Forum, which was held in May 2010 in Nouakchott, was devoted to monitoring the implementation of the Belém Framework for Action and resulted in the creation of a joint cooperation programme in this domain. 相似文献

This paper reviews data mining applications of students’ databases in educational institutions. Data mining techniques that
predict and improve students’ retention rates and success is presented. Moreover, the Missions Administration at the Ministry
of Higher Education in Egypt and previous analysis done on the missions databases is described. The focus of the paper is
to examine how data mining can help in classifying the delayed and succeeded missioners to support the implementation of a
missioners model. An investigation of how data mining can help in best or worse destinations for missioners is implemented
using the Cross Industry Standard Process for Data Mining (CRISP-DM). The paper further describes the methodology used for
analyzing the database for the ministry of higher education in Egypt. The process starts by extracting a subset of data including
the missioners and the mission’s data, countries, specialties, departure and arrival dates and finally the extension requests
from the missioners. These data were extracted into a data warehouse for the analysis purpose. The used model discovered the
best and the worst countries for student mission. A detailed analysis discovered the best and the worst specialties in the
previously discovered countries. Moreover, the analysis revealed the effect of the marital status on the mission of students
in foreign countries. A visual display using a chart was used to express the information to business users. This model may
help in supporting decision making regarding the reallocation of Egypt students to other countries. 相似文献

Through ethnographic observation and content analysis, this study aims to classify the Al-Jazeera Mubasher (AJM) newsroom according to the Schantin model of newsrooms, describe the network’s convergence level based on the Dailey, Demo, and Spillman Dynamic Scale Model, and present a unique model elucidating how, specifically, convergence works at AJM. Based on the Schantin model of newsrooms, AJM can be classified as a second-generation newsroom, a “cross-media platforms newsroom.” Convergence among the different platforms of AJM is considerable, but still below full convergence level. Accordingly, the AJM newsroom can be classified into the fourth level of the Dailey et al. Dynamic Scale Model — “content sharing.” The unique AJM-specific model presented near the end of this paper depicts the ways in which different AJM platforms function and interact inside the newsroom, explains the degree of convergence between platforms, and classifies the newsroom in terms of its convergence level. 相似文献

This work was designated to monitor the coagulation abnormalities associated with the gradual progression of liver diseases. The study included fifty patients; forty were diagnosed with liver cirrhosis with different stages categorized according to the Childs-Pugh classification and another ten patients were diagnosed with hepatocellular carcinoma (HCC). Haemostatic variables including fibrinogen (FI), calcium (FIV), transglutaminase (FXIII), prothrombin time (PT) and platelet count were estimated in patients and compared with the baseline levels of healthy subjects (n = 10). The results demonstrated that the fibrinogen level was progressively decreased, whereas PT was progressively prolonged in Child A, Child B and Child C groups. The maximum deterioration was observed in HCC patients. Calcium significantly increased in mild (Child A) and moderate (Child B) but not in Child C cirrhosis and HCC patients. FXIII level did not show any significant changes in cirrhotic patients compared to healthy group. Some of the haemostatic variables we investigated were correlated with serum albumin and bilirubin but not with aminotransferases (ALT and AST). The results indicated that the haemostatic abnormalities in fibrinogen, calcium and PT (but not FXIII) were deteriorated in parallel with the gradual regression of the constitutional function of liver. 相似文献

This paper addresses the state observation and unknown input estimation of a class of switched linear systems with unknown inputs. This class of systems may have modes in which the state is not fully observable. A state transformation allows implementing two suitable reduced-order observers. The first one, based on second order sliding mode techniques, is proposed to reconstruct the discrete state in the presence of unknown inputs. The second one, based on gathering partial information from individual modes of the switched system and on higher order sliding mode techniques, is introduced to estimate the continuous state. Then, the observer injection signal of the first second order sliding mode observer is used to estimate the unknown inputs. Simulation results highlight the efficiency of the proposed method. 相似文献

There has been considerable criticism about the effectiveness and appropriateness of degree courses in engineering over recent years. In part the criticism have related to inadequate preparation for the profession and in part to the traditional methods of teaching. As a reaction to these criticism, attempts were made at one particular technological institution to change the way in which parts of one particular course were taught. The first problem was created by a relatively high failure rate in examinations. In addition, it was felt that problem-solving was an important skill which had been inadequately taught through the conventional lecture course. Previous research had suggested that audiotapes on which students could work and take notes at their own pace might improve the examination results and help with problem-solving skills relevant to the professional engineer. The innovator found evidence for the success of the innovation in terms of a decreased failure rate and his own satisfaction with the changed emphasis in his part of the degree course. However, an independent evaluation based on interviews and observation found that other members of staff, and the students, all held different perceptions of the effectiveness of the innovation. The contrasting perceptions reflected, in part, the extent to which the staff had been involved with the innovation, and the purposes of the students in using the innovative materials and techniques. The study points up difficulties in introducing an innovation into higher education and shows the importance of the very different perceptions held by those who come into contact with the innovation. Implications for understanding the impact of learning environments on student learning, and for the introduction of innovations, are discussed. 相似文献

Recent statistics on the use of mobile technology proclaim that the world is becoming mobile. People use their phones to socialize, to conduct business, to search for information, and more. For the first time in history, people around the world have the potential to learn from any location at their own convenience. But first, education systems must change, to facilitate mobile access to education. As this article describes, the most important change will be training teachers, both in pre-service programmes and through professional development, to use the technology to design and deliver education and to create bridges to informal learning. The article also describes some projects around the world that are helping to prepare teachers for the mobile world, and some pilot projects using the technology. Most such research, however, is limited to short-term studies focusing on learners’ satisfaction with mobile learning. Future studies must consider its long-term benefits and its impacts on performance and retention. As mobile technologies emerge, teachers have to keep up with the changes so that they can take advantage of the power of the technology to design and deliver education. 相似文献

The prevalence of hepatitis C virus (HCV) infection varies across the world, with the highest percent of infections reported in Middle East, increasingly in Egypt. The current study aimed at examining the bio-statistical correlation and multiple regression analyses of pituitary growth hormone (GH) and liver activities among HCV genotype-4 patients treated with PEG-IFN-α plus RBV therapy. Herein, the current study was conducted on 100 HCV genotype-4 infected patients and 50 healthy controls. Patients received PEG-IFN-α/RBV for 24 weeks. Host RNA was isolated from patients’ sera for HCV genotyping and viral load determination. Moreover, the enzymatic activities of the liver, AFP, GH, PT, and CBC were performed in all volunteers. The present study resulted that the activities of the hepatic enzymes among HCV genotype-4 patients correlated together significantly. While, human GH showed a significant positive regression with pre-treatment ALT concentration in responders. Furthermore, multiple regression analysis for GH showed a significant positive correlation with pre-treatment ALT in HCV genotype-4 infected patients. We concluded that there were a putative significant relation between GH and pre-treatment ALT activity in HCV infection and response to IFN-based therapy. 相似文献
