An Early Story of Kho Ping Hoo

Kho Ping Hoo (1926–1994) is the most well-known of all Indonesian writers of popular silat stories, largely set in China, which describe the adventures and romances of legendary heroes famed for their skill in martial arts. It is less well-known that he began his career writing critical stories about socio-economic conditions in the late 50s and early 60s. This paper discusses one of these stories. It places the story in the context of political developments of the time, in particular as they affected the Chinese Indonesian community. The paper argues that this story and one or two others like it come at the end of a tradition of Sino-Indonesian literature which had flourished from the end of the nineteenth century until the mid-1950s. After 1960, Chinese-Indonesian writers cease writing realist fiction of any kind and write either silat stories or romantic stories set in middle class urban environments

Incentives and disincentives for reducing sugar in manufactured foods: An exploratory supply chain analysis

This policy brief presents the results of a novel food supply chain analysis that identifies insights for governments to consider when designing sugar reduction strategies. It explores the incentives and disincentives to using sugar in manufactured foods throughout the “sugar supply chain” – the actors and activities that take sugar from farm to fork. It draws on the perspectives of entities working inside this sugar supply chain to explore the following key questions: • What are the incentives and disincentives for industry to reduce the amount of sugar in manufactured food and drink products? • At what point along the supply chain do these incentives and disincentives operate? • Are there opportunities to effectively enhance the incentives and/or lessen the disincentives for reducing sugar

Probing Unquenching Effects in the Gluon Polarisation in Light Mesons

We introduce an extension to the ladder truncated Bethe-Salpeter equation for mesons and the rainbow truncated quark Dyson-Schwinger equations which includes quark-loop corrections to the gluon propagator. This truncation scheme obeys the axialvector Ward-Takahashi identity relating the quark self-energy and the Bethe-Salpeter kernel. Two different approximations to the Yang-Mills sector are used as input: the first is a sophisticated truncation of the full Yang-Mills Dyson-Schwinger equations, the second is a phenomenologically motivated form. We find that the spectra and decay constants of pseudoscalar and vector mesons are overall described well for either approach. Meson mass results for charge eigenstate vector and pseudoscalar meson masses are compared to lattice data. The effects of unquenching the system are small but not negligible.Comment: 26 pages, 13 figure

Coulomb gauge confinement in the heavy quark limit

The relationship between the nonperturbative Green's functions of Yang-Mills theory and the confinement potential is investigated. By rewriting the generating functional of quantum chromodynamics in terms of a heavy quark mass expansion in Coulomb gauge, restricting to leading order in this expansion and considering only the two-point functions of the Yang-Mills sector, the rainbow-ladder approximation to the gap and Bethe-Salpeter equations is shown to be exact in this case and an analytic, nonperturbative solution is presented. It is found that there is a direct connection between the string tension and the temporal gluon propagator. Further, it is shown that for the 4-point quark correlation functions, only confined bound states of color-singlet quark-antiquark (meson) and quark-quark (baryon) pairs exist.Comment: 22 pages, 6 figure

Probing the gluon self-interaction in light mesons

We investigate masses and decay constants of light mesons from a coupled system of Dyson--Schwinger and Bethe--Salpeter equations. We explicitly take into account dominant non-Abelian contributions to the dressed quark-gluon vertex stemming from the gluon self-interaction. We construct the corresponding Bethe-Salpeter kernel that satisfies the axial-vector Ward-Takahashi identity. Our numerical treatment fully includes all momentum dependencies with all equations solved completely in the complex plane. This approach goes well beyond the rainbow-ladder approximation and permits us to investigate the influence of the gluon self-interaction on the properties of mesons. As a first result we find indications of a nonperturbative cancellation of the gluon self-interaction contributions and pion cloud effects in the mass of the rho-meson.Comment: 4 pages, 5 figures.

Roche tomography of the secondary stars in CVs

The secondary stars in cataclysmic variables (CVs) are key to our understanding of the origin, evolution and behaviour of this class of interacting binary. In seeking a fuller understanding of these objects, the challenge for observers is to obtain images of the secondary star. This goal can be achieved through Roche tomography, an indirect imaging technique that can be used to map the Roche-lobe-filling secondary. The review begins with a description of the basic principles that underpin Roche tomography, including methods for determining the system parameters. Finally, we conclude with a look at the main scientific highlights to date, including the first unambiguous detection of starspots on AE Aqr B, and consider the future prospects of this technique.Comment: 4 pages, 4 figures.

The Senior Communicator of the Future – Competencies and Training Needs

Sanchez (2005) proposed the future leading communicator as: “the true professional [who] will be an adroit strategist, a creative technician and a skilled facilitator – a friend of technology and an exponent of life-long learning. The future is a global voyage into the art and science of communication, where the successful communicator will be like the men and women of the Renaissance, pulling it all together, but in the high tech environment of the 21st century.” (pp.10-11) Since the 1980s, starting from Broom and Dozier’s seminal studies on the nature of public relations employment and professionalism, there has been discussion of the career paths, competencies and training needs of public relations and corporate communication professionals. More recently, the Arthur W. Page Society (2007) has scoped the role of the Chief Communication Officer’s role in the Authentic Enterprise which placed the communicator at C-Level (Executive Board) or close to it (the marzipan layer) of the corporation. The research to be reported in this paper analyses the responses of leading European and international senior-level communicators as to the knowledge, skills, relationships, 360-degree vision, and managerial abilities that senior communications professionals will need in five years’ time, and what it takes to prepare the next generation of leaders in globally integrated organizations. The paper will also reflect on recent academic and practice literature about the nature of these competencies and discusses the potential methods and routes of their delivery. It will also consider the current operating situation, the challenges facing senior corporate communicators and their future needs. The outcomes will include recommendations for consideration by educators and employers, especially those operating in cross-cultural environments
