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.     

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.     

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.     

Fritz Redlich, 1892-1978: The Man and the Scholar

A bstract . Fritz Redlich (1892-1978) played a leading role in the development of the analytic approach in history and in establishing the new institutional history that combines entrepreneurial and business history and sociology. A member, in economics , of the German historical school , he spent 16 years in the chemical industry before the triumph of Nazism forced him to emigrate from Germany in 1936. After teaching at various colleges until 1942, he spent the rest of his life doing research in the libraries of Harvard University , producing several notable works in economic history , including a classical study of American banking , and pioneering in entrepreneurial history.     

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.     

Examining the role of leadership,trust for school culture and policy

Quality of life relies on also the quality of working context and the group dynamic. Culture of schools, trust and leadership facilitate quality in fostering strategic policies in establishing policy and development. The aim of the research study is to examine the role of leadership, trust for school culture in regard to the perceptions of inspectors. As this research stands on qualitative nature, experiences, perceptions of research participants shape the current understanding to give insights on the role of leadership, trust. In addition, establishing school culture is a part of quality to set policy in terms of development, inspection is a moderation of encapsulating the nature of school culture. Interview was employed to gain understanding and experiences of inspectors in relation to leadership, trust for the school culture. Mission, vision of schools, principles of schools, loyalty to schools, policies, objectives of practices in schools, social interaction in schools. Thematic analysis through laddering was done that five themes were established in examining leadership, trust in the school culture. It is important that employees in the training organization act in a joint view on implementing educational objectives. This is achieved by developing positive attitudes in people and by being able to act constructively with each other. The research results revealed that the inspectors who are currently working at the Ministry of National Education have their views on the mission, vision and leadership of schools and what they think about school culture trust in schools.

     

A review of the literature on environmental innovation management in SMEs: implications for public policies

The aim of this article is to collect and make up the most important contributions in the economic literature in relation to the special characteristics of the management of the environmental innovation in the SMEs. Specifically, we want to show their strengths and weaknesses in order to make up the main conclusions of these analyses with the literature in relation to the way Public Administrations face this situation. The scarce development in the SMEs in respect to their environmental strategy may be a consequence of the links among some of the following factors: limited financial resources, the type of organizational structure, a little influence of the strategic adaptation competence against the changes in the SMEs, the managers’ scarce environmental training and short term orientation, the staff’s scarce environmental awareness and training, the status of the environmental issues in the company, the SMEs’ lower ability to obtain highly radical innovations, the scarce influence of manufacturing process flexibility in the most advanced states of the environmental strategy in the SMEs and their lack of relation ability with external stakeholders—very important in the success of the most advanced environmental approaches. Besides, the lack of regulation neutrality must be added as a key difference among companies of different sizes. So specific actions seem be necessary, such as technological advice and awareness, and training programs in order to cooperate with external stakeholders.

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.     

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.     

Slower economic growth affects the 1995 labor market

As the pace of economic activity moderated in 1995, job growth slowed. Nonetheless, it was enough to absorb the small increase in the supply of labor, with the result that the unemployment rate remained at about the same level it had reached at the end of 1994. In the first quarter of 1995, employment grew at a brisk pace but, as the economy began to slow, job gains fell sharply. Employment growth continued at a much more moderate pace for the balance of the year, so that, by the fourth quarter, nearly 1.9 million jobs had been added to the Nation's payrolls. By comparison, in the fourth quarter of 1994 alone, payroll employment had grown by 1.1 million. Most of the job gains in 1995 were in the services industry group. Manufacturing employment, which had been rising since the fall of 1993, began to decline in the spring, and by the end of 1995, that industry group had lost nearly a quarter of a million jobs. Employment increased in most of the other major industry groups, even though declines in some of their component industries partly offset gains in others.

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.
