This pilot study presents a lunar and Gregorian chronology of the Sira, that is the biography of the prophet Muhammad. The paper discusses the problems surrounding the chronology of very early Islamic history, namely, the pre‐Hijra era. This history is not covered by the Hijra calendar, and therefore, historians dated its events using other primitive dating systems, resulting in considerable difficulties and inaccuracies when comparing Gregorian dates of this early Islamic history. In order to overcome this problem and establish an accurate chronology of the early Islamic history, the introduction of a new lunar calendar (the Muhammadi calendar) which starts with the birth month and year of the prophet Muhammad, and covers all Islamic history including the pre‐Hijra era, is suggested. The Muhammadi calendar was used to study the earliest three versions of the Sira. All dated events of the Sira were compiled from these sources and presented, for the first time, according to their historical order. The Muhammadi dates of these events were then calculated. For the first time, a computer program was designed to convert the Muliammadi dates to their Christian equivalent. The program was then used to compute the Gregorian dates of the events of the Sira.  相似文献

This paper analyzes what developing South and Southeast Asian countries are doing in order to improve the qualifications of their teachers. The first section examines the perceived inadequacies in the pre-service and in-service teacher training programs in these countries. The second section discusses how these countries have confronted these inadequacies:-by expanding in-service teacher training programs,-by improving pre-service teacher training programs, and-by trying to make teaching a more self-fulfilling profession.In the conclusion, some projections are made about future directions these countries may take to improve further the quality of their teaching personnel.
Zusammenfassung In diesem Artikel wird analysiert, was süd- und südostasiatische Entwicklungsländer tun, um die Qualifikationen ihrer Lehrer zu verbessern. Im ersten Abschnitt werden erkannte Unzulänglichkeiten in den Lehrerausbildungs- und Lehrerfortbildungsprogrammen untersucht. Im zweiten Abschnitt wird diskutiert, wie diese Länder den Unzulänglichkeiten entgegengetreten sind:-durch Ausweitung der Lehrerfortbildungsprogramme,-durch Verbesserung der Lehrerausbildungsprogramme und-indem versucht wird, Lehren zu einem befriedigenden Beruf zu machen.Zum Schluß werden einige Wege vorgeschlagen, die diese Länder in Zukunft gehen könnten, um die weitere Qualität ihres Lehrpersonals zu verbessern.

Résumé Le présent article analyse les actions entreprises par des pays en développement de l'Asie du Sud et du Sudest afin d'améliorer les qualifications de leurs enseignants. La première partie examine les inadéquations relevées dans les programmes de formation initiale et en cours d'emploi des enseignants de ces pays. La deuxième partie analyse la manire dont ces pays ont fait face à ces carences:-en développant leurs programmes de formation des enseignants en exercice,-en améliorant les programmes de formation initiale des maîtres, et-en essayant de rendre la profession d'enseignant plus épanouissante.Pour conclure, quelques projections sont faites au sujet des futures directions que ces pays peuvent suivre pour améliorer davantage la qualité de leur personnel enseignant.

Assessment has been defined as an authentic method that plays an important role in evaluating students’ learning attitude in acquiring lifelong knowledge. Traditional methods of assessment including the Computer-Aided Assessment (CAA) for mathematics show limited ability to assess students’ full work unless multi-step questions are sub-divided into sub questions. This issue persisted significant drawback especially within the notion of method marking approach. To address this issue, the aim of the study is to develop a methodological framework that will create an information and communications technology (ICT) artefact prototype. The prototype (termed as method marking assessment (MMA) artefact) implements a method-marking assessment concept to assess through multi-step questions. Extensive literature reviews have revealed that there are features in common between complex-problem solution characteristics and multi-steps questions assessment using ICT; therefore complex problems paradigm is used in the study for developing the MMA prototype.  相似文献

Objective

Heavy ion beam, which has emerged as a new mutagen in the mutation breeding of crops and ornamental plants, is expected to result in the induction of novel mutations. This study investigates the morphological and biochemical responses of Oryza sativa toward different doses of carbon ion beam irradiation.

Methods

In this study, the dry seeds of O. sativa were irradiated at 0, 20, 40, 60, 80, 100, and 120 Gy, followed by in-vitro germination under controlled conditions. Morphological and biochemical studies were conducted to investigate the morphological and physiological responses of O. sativa towards ion beam irradiation.

Results

The study demonstrated that low doses (10 Gy) of ion beam have a stimulating effect on the height, root length, and fresh weight of the plantlets but not on the number of leaves. Meanwhile, doses higher than 10 Gy caused reductions in all the morphological parameters studied as compared to the control samples. The highest total soluble protein content [(2.11±0.47) mg/g FW] was observed in plantlets irradiated at 20 Gy. All irradiated plantlets were found to have 0.85% to 58.32% higher specific activity of peroxidase as compared to the control samples. The present study also revealed that low doses of ion beam (10 and 20 Gy) had negligible effect on the total chlorophyll content of O. sativa plantlets while 40 Gy had a stimulating effect on the chlorophyll content. Plantlets irradiated between 40 to 120 Gy were shown to be 0.38% to 9.98% higher in total soluble nitrogen content which, however, was not significantly different from the control samples.

Conclusions

Carbon ion beam irradiation administered at low to moderate doses of 10 to 40 Gy may induce O. sativa mutants with superior characteristics.  相似文献

Psychiatric disorders especially depression are associated with a variety of changes in immunity parameters. In this work, an attempt was carried out to make estimation about the correlation between immunity and depression through the measuring of IgG, IgA, and IgM and complements (C3 and C4) levels in the serum of patients and comparing them with the corresponding levels of healthy control group. The results showed a significant increase in serum level of C3, C4, cortisol, IgG and no significant differences were noticed in the level of IgA and IgM in the depressed patients group as compared with control group. A slight positive correlation was observed between cortisol versus IgG in depressed patients that is not found in normal subjects. Thus in depression, human body defenses psychologically and sometimes this defense transformed into immunological resistance that is expressed as different measurable changes in immunological parameters.  相似文献

ABSTRACT

The tomb of Tutankhamen in the Valley of the Kings, Egypt, one of the major attractions of the World Heritage Site of Ancient Thebes and its Necropolis on the West Bank of modern day Luxor, is today a destination for mass tourism. Visitors to the tomb increase relative humidity, elevate carbon dioxide levels, and encourage natural ventilation which facilitates entry of dust into the tomb. These conditions negatively impact the wall paintings and remaining artifacts in the tomb and create an uncomfortable environment for visitors. The deposition of dust inside the tomb collects on uneven wall painting surfaces, obscures their legibility and necessitates cycles of cleaning, which in turn leads to further damage. Developing environmental management strategies in the tomb to counter the effects of visitors and mitigate dust entry is an important component of the collaborative project between the Getty Conservation Institute (GCI) and Egypt’s Ministry of Antiquities (MoA) to conserve the tomb. These included implementation of a filtered-air supply and exhaust ventilation system to stabilize the interior microclimate and reduce dust in order to improve visitor comfort and contribute to the long-term preservation of the tomb.  相似文献

This study investigated the seated activity among children educated in special schools and their adult carers in two sensory gardens in the United Kingdom. Seated activity was established whether the seating was used as intended or whether users preferred to sit on other attributes during their learning session. The objectives of this study are to explore opportunities for users' activity and their engagement with the attributes, whether activity is possible or if opportunities are not being actualised because of barriers. Observation and behaviour mapping methods were carried out alongside affordance theory. The outcome suggests that the number of users, the number of attributes and the total area of the zone did not relate to the median time spent per user; rather, it was the richness of the attributes that did so.  相似文献

The Byzantine emperor Theophilus (829–842) is recorded as having commissioned a palace in the style of contemporary Abbāsid palaces in Baghdad near Constantinople, making it an important instance in the visual cultural exchange between Byzantium and Islamdom. One widely held explanation suggests that Theophilus had a taste for the arts of Islamdom. This paper argues that the Abbāsid‐style palace of Theophilus should be placed in the context of contemporary political events and Theophilus's architectural patronage. The palace can then be seen as the product of Byzantine‐Muslim political and cultural rivalry mediated by an increasingly shared culture of objects that included architectural concepts.  相似文献
