supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
BACKGROUND AND AIM: The study aimed to assess the frequency of head and face injuries in motorcyclists who had an accident and to find out the relationship between helmet use and frequency of these injuries. METHODS: A cross-sectional study with multi-stage sampling method provides data on the injured motorcyclists with road accidents. Data came from a registration form which has documented inf...
On any plausible account of the basis for health care resource prioritization, the benefits and costs of different alternative resource uses are relevant considerations in the prioritization process. Consequentialists hold that the maximization of benefits with available resources is the only relevant consideration. Non-consequentialists do not reject the relevance of consequences of benefits a...
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
Accidents and congestion are two frustrating events, which can be observed very frequently on roads. Accidents, especially on expressways, can trigger heavy traffic congestions imposing huge external costs and reducing the level of service. Therefore it is obvious that accidents clearly have an impact on congestion. But the opposite, i.e. the effect of congestion on occurrence of accidents, is ...
INTRODUCTION The costs of traffic accidents in low- and middle-income countries are estimated to add up to $65 billion annually, which is a little higher than the amount they receive as a final aid for development. The present retrospective study aims to evaluate the treatment costs of the hospitalized injured individuals in traffic accidents. METHODS The present study was carried out in Imam...
Quantifying the costs of climate change requires measurement of direct effects as well as behavioral responses. While behavioral responses have been shown to increase costs, we identify responses that reduce costs, which we define as ‘voluntary exposure.’ We quantify the response of the transportation sector in terms of traffic accidents and travel demand to daily variation in weather. We find ...
