    Managing Supply Chain Networks: A Framework for Achieving Superior Performance through Leadership Capabilities Development in Supply Chain Node

    Get PDF
    Leadership capability is acknowledged as a major challenge for organizations and a pre-requisite for sustaining high levels of organizational performance and supply chain competitiveness. Recent research highlights how globalisation has led to the extension of domestic supply chains, particularly SME ones, to include both suppliers and customers globally. This paper examines the role capabilities development in managers and leaders as nexus of their supply chain networks have to play in achieving better performance through case studies. Once banished to the backburners of business management thinking, leveraging core leadership competencies is now critical to company‟s superior performance in supply chain networks

    A3_2 It's Snow Problem

    Falling into a pile of snow can sometimes feel like falling into a cold, wet and slightly uncomfortable cushion. Although it may not be the most enjoyable way to break a fall, the fact remains that snow can dampen the force you experience and subsequently make the fall less painful (but unfortunately, no less embarrassing). In this article we calculate how much snow it would take to make a deadly fall, survivable. For a 70kg body falling at terminal velocity, the height of snow required to reduce the deceleration to a survivable 10 g was found to be 17.8 m

    Artistic licence often tests fundamental physical laws in contemporary cinema, allowing for unrealistic yet creative scenes. Nevertheless, these improbable scenarios can be valuable exercises in applying our physical knowledge to unique situations. From the 1999 movie Toy Story 2, we calculated the spring constant of Slinky the Dog's spring and the friction coefficient between his paws and the rooftop he was standing on. The value for the spring constant was found to vary between 9.04 N/m and 2.63 N/m and the friction coefficient was found to vary between 1.69 and 4.90. These are then compared to typically used values to assess the scenario's plausibility

    As always, films are a great place to look for physical inaccuracies and impossibilities. One such film is Disney's 'Pirates of the Caribbean', where they walk underwater within a capsized row boat. From resolving the buoyancy and weight forces, the resultant force is 13230 N opposing the force of weight, which will act to push the boat up to the surface. From this we conclude that it is not possible for them to be able to traverse underwater in this fashion

    The idea of swinging on a vine as a means of travel within a jungle is one that has been used in a variety of contexts; while the physical act may be difficult to do, modelling the action and calculating some value for the average horizontal ground velocity can be done with relative ease. Within films and books it has been used for many years; the chase scene from the movie 'Indiana Jones and the Kingdom of the Crystal Skull' is one such film. From investigating this scene the average horizontal ground velocity of Shia la Beouf is found to be 15.3 ms^-1

    A3_3 This Time Next Year, We'll be Millionaires!

    The path to ‘getting rich quick’ is one fraught with instability and conjecture. In the British sitcom Only Fools and Horses, stock marketer Del Boy Trotter notoriously claims that “This time next year, we’ll be millionaires”. In this article we utilise the special relativistic phenomenon that is time dilation to calculate the conditions under which this feat would be possible. We found that by investing $3000 in three companies in the 1980s, travelling at 0.999c for 12 ly and instantaneously turning around to undergo a return journey, Del Boy Trotter could have become a millionaire in only a year.
