As has been apparent for the past several years, online education emerged as a powerful contender next new technology. Although previous technological breakthroughs that have failed to live up their initial promise, this time is different. Several courses run in recent taught many thousands of students various topics. The human experience about change; we should understand issues behind phenome...

Telomeres are DNA-protein complexes at the ends of chromosomes that control genomic integrity but appear to become shorter with age and stress. To test whether stress causes telomere attrition, we exposed the offspring of wild-caught house mice (Mus musculus) to stressful conditions and examined the changes in telomere length over six months. We found that females exposed to males and reproduct...

Develop an advanced unified hybrid radio propagation model based on parabolic equation and rayoptics methods for both surface-based and airborne applications. This model is named the Advanced Propagation Model (APM) and is the model used in the Advanced Refractive Effects Prediction System (AREPS). Other objectives are to develop a propagation model for earth-satellite geometries suitable for i...

Here ‘likely’ is defined as having an assessed likelihood of 66-100%. 2. These figures are from the Technical Summary of Working Group One’s contribution to the Fifth Assessment Report of the IPCC. This Summary is available...

There is growing scientific evidence that, as a result of increasing anthropogenic carbon dioxide (CO2) emissions, absorption of CO2 by the oceans has already noticeably increased the average oceanic acidity from pre-industrial levels. This global threat requires a global response. According to the Intergovernmental Panel on Climate Change (IPCC), continuing CO2 emissions in line with current t...

Protected areas (PAs) dominate conservation efforts. They will probably play a role in future climate policies too, as global payments may reward local reductions of loss of natural land cover. We estimate the impact of PAs on natural land cover within each of 147 countries by comparing outcomes inside PAs with outcomes outside. We use 'matching' (or 'apples to apples') for land characteristics...

Introduction: Draught is being considered as a climatic reality in arid and semi-arid regions such as Iran. Drought is capable of generating drastic impacts over water and soil resources, vegetation, animals and human beings. Water is a prominent factor as far as agricultural product is concerned specially in arid zones. Draught and its impact on water resources will bear unpleasant conseque...

This paper presents the results of a case study on the impacts of implementing Enterprise Content Management Systems (ECMSs) in an organization. It investigates how these impacts are influenced by the functionalities of an ECMS and by the nature of the ECMS-supported processes. The results confirm that both factors do influence the impacts. Further, the results indicate that the implementation ...

We conduct the largest ever investigation into the relationship between meteorological conditions and the sentiment of human expressions. To do this, we employ over three and a half billion social media posts from tens of millions of individuals from both Facebook and Twitter between 2009 and 2016. We find that cold temperatures, hot temperatures, precipitation, narrower daily temperature range...
