Corroborating social media echelon in cancer research

Worldwide medical facilities differ, and for this reason, the causes of death can vary. Cancer is considered the second leading cause of death after heart disease worldwide, and the same causes of death are observed in the United States (US). Therefore, the purposes of this study are to explore worldwide research levels in the field of cancer and the social collaboration of researchers and institutions in this field. This article examines the structural patterns of international co-authors and co-institutions in science citation index papers in cancer research. The study uses measures from the social network analysis method, including degree centrality, betweenness centrality, eigenvector centrality, and effectiveness, to investigate the effects of social networks in the area of cancer research. Empirical analysis results identify the US is the most central country, followed by Germany, Italy, France, and China, in terms of co-authored networks in this research field. Institutional analysis results indicate that the University of Milan is at the top in terms of degree centrality. The Gustave Roussy Cancer Campus in France and German University of Düsseldorf occupy the second and fourth positions, respectively. The University of California in Los Angeles and Harvard University, both in the US, are at third and fifth positions, respectively.

The Geography of Innovation in China and India

The BRICS countries in general, and China and India in particular, are now widely regarded as the areas of the world likely to challenge the economic leadership of the United States (US) and the European Union (EU). A large part of this challenge will come from rapid technological catch‐up by China and India. Yet, despite a recent rise in interest, there is limited knowledge about how and where innovation takes place in these two leading emerging countries and to what extent the Chinese and Indian territorial systems of innovation differ from those in the EU or the US. In this article we explore the geography of innovation in China and India, concentrating on understanding key territorial‐level innovation trends by country, region and technology field, using the US and the EU as benchmarks. We find significant contrasts between the geography of innovation in China and India and that of the US and the EU. First, the degree of concentration of innovative activities in both countries is extremely high. Levels of agglomeration of innovation in the coastal provinces of China, as well as in Delhi and the South of India, significantly exceed the levels of agglomeration found in the USA and the EU. Secondly, China has witnessed a more rapid increase in the degree of concentration of innovation than India. We posit that the differences in the geography of innovation between, on the one hand, China and India and, on the other hand, between these countries and the developed world are rooted in different institutional settings, different systems of innovation and different national innovation strategies.

Using extreme value theory to measure value-at-risk for daily electricity spot prices

The recent deregulation in electricity markets worldwide has heightened the importance of risk management in energy markets. Assessing Value-at-Risk (VaR) in electricity markets is arguably more difficult than in traditional financial markets because the distinctive features of the former result in a highly unusual distribution of returns—electricity returns are highly volatile, display seasonalities in both their mean and volatility, exhibit leverage effects and clustering in volatility, and feature extreme levels of skewness and kurtosis. With electricity applications in mind, this paper proposes a model that accommodates autoregression and weekly seasonals in both the conditional mean and conditional volatility of returns, as well as leverage effects via an EGARCH specification. In addition, extreme value theory (EVT) is adopted to explicitly model the tails of the return distribution. Compared to a number of other parametric models and simple historical simulation based approaches, the proposed EVT-based model performs well in forecasting out-of-sample VaR. In addition, statistical tests show that the proposed model provides appropriate interval coverage in both unconditional and, more importantly, conditional contexts. Overall, the results are encouraging in suggesting that the proposed EVT-based model is a useful technique in forecasting VaR in electricity markets.     

WORLD OUTLOOK

The world economic recovery, which began in the late summer of 1980, can now be seen as premature, in as much as 1980's short, sharp recession had achieved only a limited reduction in the rate of inflation. Economic policy, particularly in the United States, is once more geared to a reduction in the inflation rate even if this imposes costs in terms of lost output and higher unemployment. The consequent appreciation of the US dollar against the European currencies has - in spite of weakening oil and non-oil commodity prices in dollar terms - produced a further boost to European inflation and a subsequent tightening of policy in some countries, notably West Germany. In these circumstances we expect little or no growth in output in the world economy until the summer of 1982.     

A Conversation with Jef Teugels

Jozef Lodewijk Maria Teugels was born in Londerzeel, Belgium, on February 20, 1939. He received his high school education at Sint-Lievenscollege in Antwerp. He obtained a Candidate diploma in Physics in 1961 and a License degree in Mathematics in 1963 at the Catholic University of Louvain. After serving one year in the army, he obtained his MSc in 1966 and his PhD in 1967 at Purdue University, with Marcel F. Neuts as advisor. In 1967 he was appointed at the Catholic University of Louvain and promoted to Full Professor in 1973. He remained in Leuven until his retirement in 2004. He chaired the Department of Mathematics over the periods 1970–77 and 1982–89. He has held visiting positions at numerous universities in the United Kingdom, Portugal, the United States of America, South Africa, Japan, Indonesia and Australia.     

Savings and the Budget

The fall in the personal sector savings ratio to a record low last year has been a major factor behind the rapid growth of domestic demand in the past two years and the associated deterioration in the current account. It is also a major uncertainty in the Chancellor's Budget judgement. Existing econometric relationships for the consumption function have failed to predict the fall in personal savings over the past few years. Possible explanations include statistical error, the effects of financial deregulation, the housing boom, expectations of higher growth in incomes, and demographic influences. In this Viewpoint, we report on a new consumption function that successfully explains the decline in savings. It provides evidence of a major demographic influence resulting from the decline in the proportion of the population in the 45–64 age cohort, the main savers in society. Subsidiary effects arise from the boom in house prices, and statistical mis-measurement. The equation predicts an appreciable revival of savings over the next few years as the 45–64 age cohort grows again. These shifts in demographic structure reflect the after-effects of the Second World War. This new evidence suggests that the Chancellor has done quite enough to ensure a slowdown in consumption, and that he would be ill-advised to heed calls for special measures to boost savings. By contrast, well conceived tax changes that remove microeconomic distortions in the tax system (perhaps moving in the direction of an expenditure tax) would improve the tax structure, and may well increase the scope for tax cuts in future budgets. Our new consumption function also lends weight to the Chancellor's argument that the current account deficit is not a source of concern, insofar as it arises from a shift in savings associated with demographic changes that will be reversed in due course.     

Evolution in a General Equilibrium framework

In this paper, we consider a general equilibrium model in which the economies are characterized by the distribution of firms on a set of branches of production; we will show that based on the decisions of the managers of the firms, it is possible to build a dynamic system whose solutions reproduce the possible trajectories of the economy. Once the initial state of an economy is known, that is, the initial distribution of firms, we will have a unique solution for this dynamic system, which will coincide with the evolution of the economy, that is, the evolution of prices and equilibrium allocations.The investment decisions of the administrators of the companies will change the distribution over the set of existing productive branches, which in turn will produce changes in the wealth of consumers who are also shareholders of the companies and then as a consequence, their demand will change, and therefore the equilibrium allocations and prices will too.In most cases, these decisions lead to an improvement in the efficiency of the productive side of the economy and an increase in the welfare of the economy as a whole, but, as we will show, under some particular circumstances, even when it comes to rational decisions from the point of view of administrators, this can lead to undesirable repercussions on the welfare of consumers. Besides, in a neighborhood of a critical economy, even when these decisions may involve small changes in the distribution of companies, they can cause abrupt and unexpected changes in the behavior of the economy, or in other words, they can cause an economic crisis. These are characterized by large changes in the prices, in the demand, and in the supply of goods. In contrast, in a sufficiently small neighborhood of a regular economy, small changes in the distribution of firms produced by the investment decisions of managers do not lead to large changes in the subsequent behavior of the economy. We will exemplify these statements with several numerical examples.     

Managing AIDS in Africa: HRM challenges in Tanzania

The impact of the AIDS epidemic in developing countries, and in Africa in particular, is now a matter of great concern to policy makers, managers, and academics on a global scale. The magnitude of the potentially disastrous effects of the disease has severe implications for management in organizations, and, in particular, for HRM. The AIDS epidemic is imposing, and will continue to impose, in the foreseeable future, a significant burden on the way people are managed. Little has been written on HRM in Africa, and the present literature on AIDS and HRM in Western societies is inappropriate and insufficient in relation to African organizations. Fifteen organizations in Tanzania took part in this study, which is probably the first of its kind, to produce a picture of current developments and approaches in managing people under the threat of AIDS.     

公众参与原则与我国城市规划立法的完善

公众参与城市规划是城市居民能够直接而积极地参与城市规划、成为规划制定和规划实施过程中一个重要的组成部分.它对于减少规划失误、促进规划的顺利实施及监督规划部门依法行政具有独特的法律价值.公众参与城市规划的原因在于解决规划失灵问题,是恢复个人利益与公共利益平衡的重要杠杆.借鉴各国公众参与制度,我国的公众参与机制应从城市规划信息公开、赋予社会公众参与城市规划的主体地位、确立公众参与城市规划的程序、明确公众参与城市规划的方式以及强化公众参与城市规划的司法保障等方面进行建构.

A Conversation with James O. Ramsay

Jim Ramsay was born on September 5, 1942, in Prince George, British Columbia. He pursued undergraduate studies at the University of Alberta, where he completed a BEd in 1964 with a major in English and a minor in mathematics. He then specialized in statistics and psychometry, earning a PhD in psychology from Princeton University in 1966. After holding a temporary lectureship in the Department of Psychology at University College London for one year, he joined the Department of Psychology at McGill University, where he rose through the academic ranks. He was chair of his department from 1986 to 1989 and spent sabbatical leaves in Cambridge, Grenoble, and Toulouse. He was named professor emeritus upon his retirement in 2007. Jim is the author of four influential books and over 100 peer‐reviewed articles in statistical and psychometric journals. He developed much of the statistical theory behind multidimensional scaling and is widely recognized as the founder of functional data analysis. Three of his papers were read to the Royal Statistical Society, and another won The Canadian Journal of Statistics 2000 Best Paper Award. The Statistical Society of Canada (SSC) awarded him a Gold Medal for research in 1998 and an honorary membership in 2012. Jim was president of the Psychometric Society in 1981–82 and president of the SSC in 2002–03.

Top pay transparency in Europe: codes,convergence and clichés

Following the waves of corporate scandals and the increasing attention to corporate governance, the transparency of reporting on director-level pay has increased across Europe. This article examines the extent of convergence in laws, codes and corporate reporting practices in regard to director-level pay in France, Germany, Switzerland and the UK. The paper analyses annual reports and the websites of 23 companies, using institutional theory to discuss the coercive, normative and mimetic pressures for convergence that are revealed, not just in the laws and codes in each country, but also in the standardized wording in the relevant sections of reports which have become clichés.     

A Complete Decomposition of Unemployment Dynamics using Longitudinal Grouped Duration Data*

In this paper, we study the unemployment dynamics in the Belgian regions, Flanders and Wallonia, on the basis of aggregate stratified data covering the period 1973–93. We decompose the aggregate exit probability from unemployment into calendar time and, both observed and unobserved, compositional effects. We find that changes in the inflow composition affect the cyclical fluctuations in unemployment duration only marginally. However, the long‐run improvement in the quality of entrants into unemployment, notably in terms of educational attainment, mitigates the strong upward trend in this duration. This is a new result as none of the existing studies purges the trend in the aggregate outflow rate of the variation in its composition. We also conclude that in Belgium, incidence explains as much as 45% of the evolution of unemployment. Finally, the diverging evolution of unemployment across Flanders and Wallonia predominantly results from a stronger decline in the exit rates from unemployment in Wallonia.     

Prices and Wages

Inflationary pressures cooled over the latter months of 2013, with CPI inflation finally moving back to the 2% target for the first time in four years in December. The slowdown in inflation was largely a function of base effects; big rises in food prices in the autumn of 2012 were not repeated last year and increases in domestic energy bills, while still very large, were also lower than in the previous year. In addition, the impact of higher university tuition fees was smaller in 2013 than in 2012, which also helped to slow inflation a little…
