Are we transit into yet another phase

Are the golden years a myth in Singapore? Good morning Mrs Tian and fellow classmates. As hair fades into grey and wrinkles become increasingly prominent, we transit into yet another phase of life —— old age. A time many perceive to be a prime to enjoy the fruits of our labour. Yet, expectations may not always translate into reality. In actual fact , we live in a world fraught with insurmountable challenges. Indeed, the new age has brought forward a new set of complications we were once stranger to. With all these in mind, has the perceived golden years evolved into a myth with the passage of time or is the future of retirement still one that embodies the pleasure once promised to us?That said, it is no exaggeration to…

The of vehicle in organisation by determining

The vehicle routing problem is used to find an optimal solution to find the best route for the fleet of vehicle in organisation by determining the vehicle capacity, number of customers, time taken, distance form depot location to customer location, total demand etc. are taken into consideration. The ultimate aim of vehicle route optimisation is to reduce the cost of the transport, and also increase the efficiency of the transportation system of the organisation by reducing the travel time or distance. (Clarke and Wright, 1964, Prins, 2004; Cordeau et al, 2007a; Perboli et al, 2008).   A CVRP added with time constrain becomes a vehicle routing problem with time windows (CVRPTW). The customers have to be served within the given time window. It is defined by the number of vehicle…

A mai román társadalom a konzervativizmus és a nemek közötti egyenl?tlenség bizonyos jegyeit viseli, melynek jelenléte a totalitárius és az 1989 után újraéledt pretotalitárius örökséggel magyarázható. Románia egyik jelent?s sajátossága, hogy a feminista mozgalmak által szorgalmazott követelések, minden szervezkedés és harc híján teljesültek, ilyenek például: a n?k szavazati jogának a biztosítása, a munkához való jog elismerése, a terhesség megszakításának a joga, valamint a gyermekgondozási szabadsághoz való jog -1997-t?l napjainkig- törvényesítése. 1 A kommunizmus idején Kelet-Európában gyakorlatilag minden n?nek volt munkahelye, azaz a munkaer?piacon majdnem ugyanannyi n? volt jelen, mint férfi.

A kommunista országokban él? n?k helyzete csupán kis mértékben…

India, subcontinent. The British government is morally

India, as a modern nation, inherited a number of historical symbols and even parts of its national symbols from the British Raj. The Lutyens era Parliament Building, Supreme Court and Railway Stations in Delhi, Bombay , Kolkata and Mumbai are some reminders of our past association with the British. As power changed hands from the British Raj to the Congress led government these very symbols became those of national pride from those of colonial oppression. People have often argued that the British were responsible for giving to India a number of modern institutions like an independent judiciary, democratic government, a telecommunications network and a modern postal and railways system. They argue that these were the very foundations on which our founding fathers, led by Jawaharlal Nehru embarked upon their five…
