exposure

Score for exposure factor is the sum of scores for the five criteria of precipitation, temperature, wind, weather phenomena, and horizontal visibility. Hourly data on precipitation, temperature, relative humidity, weather condition codes, and horizontal visibility obtained at 23 synoptic stations in the Province, and from those located in an area within a radius of 100 kilometers from the borders of it, since the time they were established up to the end of 2012, was first received from Iran Meteorological Organization. Those stations were then selected that had data related to eight daily measurements in the interval 1990-2010. Based on this, data processing was carried out for nine stations (five in Kermanshah Province and four in neighboring Provinces) within MATLAB environment. The scores for exposure factors for climate change in two five-year intervals were calculated to assess climate vulnerability of Kermanshah Province. In the next stage, the study period was divided into three intervals: the base interval (from 23, 9, 1990 to 21, 9, 2000), the first interval (from 22, 9, 2000 to 22, 9, 2005), and the second interval (from 23, 9, 2005 to 22, 9, 2010). Following that, exposure criteria and markers were determined. It was then necessary to define and measure a broad range of markers because of the temporal-spatial non-uniformity in the climate of Kermanshah Province that results from land location and variety in this Province. In the present research, climatic data was processed in the framework of five criteria that included 29 markers. In general, it was found that Kermanshah Province is faced with increased hazards resulting from current changes in climate.

Cyberbullying is a form of bullying meted out online using digital devices and platforms. This study investigated the types of cyberbullying undergraduate students in Kenyan universities experience. Specifically, it sought to determine the students’ presence on Facebook, establish how the students used Facebook, identify the types of cyberbullying they experienced, and recommend strategies of mitigating cyberbullying as a means of making Facebook safer for undergraduate students in Kenya. The study was conducted using mixed research methods. Data was collected from 4770 undergraduate students and 24 deans of students in 16 public and 8 private chartered universities in Kenya. Quantitative data was collected from the students’ using questionnaires while qualitative data was collected from students using focus group discussions and deans of students using key informant interviews. Quantitative data was analysed statistically using STATA while qualitative data was analysed thematically using ATLAS.ti. The findings of the study confirm the popularity of Facebook among undergraduate students in Kenya. Students use the platform mainly for dating, business, academics and politics. The main types of cyberbullying experienced by the students on Facebook include shaming, impersonation, blackmail, exposure and cyberstalking. In dealing with cyberbullying, university authorities should create awareness about the vice among their students; the affected students should be counselled to overcome the effects of cyberbullying; and students should be advised to be vigilant in cyberspace. The findings of this study may be applied by universities to develop a students’ support service model that makes it easy to detect and mitigate cyberbullying.
