Since long many have believed in trait theory of leadership – differentiating leaders from non-leaders, by focusing on personal qualities and characteristics that are claimed to be acquired by birth. In other words, believers of trait theory say – leaders are born. They are born with some specific qualities called “traits” that make them leaders, and those who are not born with those traits can never be leaders. Modern research on leadership has disproved such claim. Leaders are not necessarily born. They are made. By observing and analyzing leaders in various organizations, and scanning through research literatures on leadership traits, an effort is made to identify some common traits in established leaders in organizations. This article is intended to sensitize the aspired organizational or business leaders on acquiring those common qualities or traits that will sharpen their leadership skills and help them emerge as leaders. The traits suggested are – ambition, desire to lead, multiple intelligence, honesty and integrity, self-confidence, job relevant knowledge and flexibility which can be acquired to be a leader.

Radio ducting is a known problem in the coastal areas of the world where it is evident that they occur frequently and their probabilities of occurrence pose enough operational effects on current radio communication signals. In this work, Advance Refractive Effects Prediction System (AREPS) is employed to characterize the tropospheric condition of Libreville troposphere. The results showed that in Libreville, the altitude where pronounced ducting phenomenon occurs majorly is within the first 160m above sea level. More so, there is an increasing order of variability and well-formed duct layers. The mean thickness of the layer over which ducting conditions occurred is usually very small for near surface events and large for the upper tropospheric events. Duct presence is throughout the year and conspicuously varied all year round.

Accident constitutes a very serious threat to human life. The rate at which accident occurs on our road has become so alarming and calls for urgent attention. To curb the menace of road traffic crash, there is need for timely reporting of accident occurrence to the rescue station. The major means of reporting road accident is through wireless technology assisted solution. Wireless technology technique commonly employed in the reporting of road accident is Vehicular Ad-hoc Network (VANET) or Global System for Mobile communication (GSM) or combination of both. VANET is an ad-hoc network that allows vehicle to vehicle and vehicle to infrastructure communication provided they are within communication range. Whereas, GSM is a communication standard based on wireless technology used to transfer voice on cell phone networks and also provides other services such as text messages, picture messages and MMS (multimedia messages). Prompt reporting of accident to the rescuing team will lead to quick response to accident victims, which invariably will result to decline in the number of deaths and loss of property. This paper seeks to survey accident reporting systems that are based on wireless technology (VANET or GSM). We provided a brief overview of wireless network, VANET and GSM wireless technology. We equally considered weaknesses of VANET-based reporting system and GSM-based reporting system and suggested the integration of Internet of Things as the best accident reporting option for Nigeria.
