Applied econometric analyses of market integration based on price data alone have been criticised, because they neglect the role of transaction costs. To meet this objection threshold vector error correction models are used. Threshold models can account for the effects of transaction costs in price transmission without directly relying upon information about these costs, which are often unavailable. Results from threshold models that are based on two thresholds provide results that are economically more intuitive than those obtained from one threshold models. However there is no adequate econometric test for threshold significance in a two- threshold model available so far; such tests are only available for the one threshold model. In this paper a restricted two-threshold model is developed in which the significance of the thresholds can be tested. This model is therefore amenable to economic interpretation and statistical inference. This model is used to estimate market integration on the European pig market.

In this paper, models for estimating the maximum price consumers are willing to pay (MPWTP) for organic beef meat, and the maximum quantity-constrained price (i.e., when buying the same quantity they bought of regular meat) consumers are willing to pay (MQCP), are presented. To this purpose, the relevant theoretical and econometric approaches are presented, based on the RUM model and on a Contingent Valuation technique.

This paper proposes the assessment of sustained superior performance by means of two measures called Static Performance and Dynamic Performance. The first evaluates the attained superior performance, and the second gauges its sustainability over time. This proposal builds primarily on the fact that, under the strategic management perspective, a firm's prevalent objective is the pursuit of sustained superior performance. Three basic conceptual dimensions stem from this objective: relativity, sign dependence, and dynamism. They serve as the foundation to the two performance measures presented. In contrast to the measures and methods in extant literature, our proposal provides: (i) a dynamic approach by considering the progress or regress in performance over time; and (ii) a cardinal measurement of performance differences and its changes over time. The paper also develops an axiomatic framework that any measure of strategic performance should comply to be theoretically and managerially sound. Finally, an empirical application to the Spanish banking sector during 1987-1999 is used to illustrate the measures.

This paper employed a robust stochastic efficiency decomposition technique that accounts for scale effects to derive the technical, allocative, and overall productive efficiency of two samples of farmers, participants and non-participants in the New Extension Program (NEP), in two agro-climatic zones in eastern Ethiopia. Using data for the 2001/2002 agricultural year, we find that both groups of farmers in the two zones have considerable overall productive inefficiencies. In the wet highlands, although the participants in NEP used a superior technology and have higher technical efficiencies, their allocative efficiencies turned out to be lower than the non-participant farmers, relative to their respective technologies. However, both groups exhibit similar productive efficiencies. In the dry lands, apart from using homogeneous production technologies, the two groups do not have significantly different technical and allocative efficiencies and that they have similar productive efficiencies.

Therefore, we find no empirical evidence of a positive impact of NEP on overall productive efficiency in both agro-climatic zones. An investigation of the influence of several socioeconomic and institutional factors revealed that education, credit, previous participation in extension programs, off-farm income and the share of the leading cropping system have a positive impact on efficiency.

Using a two-year panel of 1,422 Kenyan households surveyed in 1997 and 2000, we measure how working age adult mortality affects rural households’ size and composition, crop production, asset levels, and off-farm income. First, the paper uses adult mortality rates from available data on an HIV-negative sample to predict the proportion of deaths observed between 1997 and 2000 due to AIDS. Next, using a difference-indifferences estimation, we measure changes in outcomes between households afflicted by adult mortality vs. those not afflicted over the three-year survey period. The effects of adult mortality are highly sensitive to the gender and position of the deceased family member in the household. Households suffering the death of the head-of-household or spouse incurred a greater-than-one person loss in household size. The death of a male head-of-household between 16 and 59 years is associated with a 68% reduction in the net value of the household’s crop production. Female head-of-household or spouse mortality causes a greater decline in cereal area cultivated, while cash crops such as coffee, tea, and sugar are most adversely affected in households incurring the death of a male head-of-household. Off-farm income is also significantly affected by the death of the male head-of-household, but not in the case of other adult members. The death of other working-age family members is partially offset by an inflow of other individuals into the family and has less dramatic effects on the households’ agricultural production, assets, and off-farm income. The effects of adult mortality are also sensitive to the household’s initial asset levels. Lastly, there is little indication that households are able to recover quickly from the effects of working-age head-of-household adult mortality; the effects on crop and non-farm incomes do not decay at least over the three-year survey interval.

Монография Словенского исследователя медиа Славко Сплихала – одна из международно известных немногих книг, посвященных СМИ Восточной Европы после распада социалистического блока. Опираясь на нормативные концепции, в частности, на понятие гражданского общества, автор, тем не менее, четко разводит желаемое и действительное. В книге представлен анализ основных тенденций развития восточноевропейских СМИ после 1989 года, в особенности во взаимосвязи с трансформацией политических режимов и с приватизацией; рассматриваются причины отличия этого развития от социальных ожиданий и надежд начала 1990-х, а также намечаются пути преодоления этого разрыва.

Базовый учебник по масс медиа рассчитан на студентов различных специальностей, интересующихся данной тематикой. В отличие от более традиционных институциональных подходов, этот учебник уделяет большее внимание СМИ как части культуры, хотя и не концентрируется только на этом аспекте их функционирования. Основная предпосылка авторов учебника – масс медиа можно понять только в их контексте – институциональном, экономическом, социальном, культурном и историческом. Авторы назвали книгу «Медиаделание», т.к. они исходят из предположения, что медиа активно участвуют в создании своего собственного контекста, своей окружающей среды и общества, в котором они существуют, даже не смотря на то, что и сами они являются его продуктом. Авторы рассматривают такие темы как: исторические нарративы о СМИ, медиа-организации и люди, занятые в сфере медиа-производства; масс медиа и создание смыслов, интерпретаций, идеологий, идентичностей и др.; потребление СМИ и медиа-эффекты; СМИ и политика; нормативные теории СМИ; СМи и глобализация и др. Все эти темы традиционно рассматриваются и в других учебниках, однако авторы утверждают, что их подход к этим темам отличен от других.

The book provides a broad overview of the way medicine is experienced, perceived and socially constructed in western societies. Drawing on the tradition of the sociology of health and illness, Deborah Lupton directs readers to an understanding of medicine, health care, illness and disease from a sociocultural perspective. At a time of increasing disillusionment with scientific medicine and the mythology of the beneficent, god-like physician, there is also - paradoxically - a growing dependence on biomedicine to provide the answers to social as well as medical problems. This book illuminates why attitudes to medicine are characterized by such strong paradoxes, and why issues of disease, illness and the medical encounter are surrounded by controversy, conflict, power struggles and emotion.

The social history of medicine over the past fifteen years has redrawn the boundaries of medical history. Specialized papers and monographs have contributed to our knowledge of how medicine has affected society and how society has shaped medicine. This book synthesizes, through a series of essays, some of the most significant findings of this "new social history" of medicine. The period covered ranges from ancient Greece to the present time. While coverage is not exhaustive, the reader is able to trace how medicine in the West developed from an unlicensed open market place, with many different types of practitioners in the classical period, to the nineteenth- and twentieth-century professionalized medicine of State influence, of hospitals, public health medicine, and scientific medicine. The book also covers innovative topics such as patient-doctor relationships, the history of the asylum, and the demographic background to the history of medicine.

Historians have long noted the intense debates nineteenth- and twentieth-century scholars had over the concept of work, but few are aware of the medieval debates over work that set the stage for modern discussions. Indeed, medieval society established the framework within which modern Western ideas about work have grown. It is essential, therefore, that we learn what medieval thinkers had to say on the subject. This study addresses this need by examining the thought of Peter Damian and numerous other religious leaders and groups of the High Middle Ages for evidence of their contributions. The result is a deepening of our historical understanding of the concept of work as well as widening our appreciation of the modern world's debt to medieval society.

Mentoring continues to be one of the fastest growing techniques in human resource management. It’s viewed as being an essential building block of modern management development. Can one technique apply to pupils making a transfer from school to work and to the most senior executives? What is mentoring and why is it so popular?
Now in its second edition, Mentoring in Action answers these questions plus many more and continues to examine a variety of mentoring schemes through a multitude of new, insightful case studies.

The European Union beef market regulation is largely influenced by the Common Agricultural Policy (CAP). With the 1992 CAP reform, there was a partial shift by the EU from product price support to a more direct form of income support by way of direct payments. For beef there was a move to direct payments on intermediate products which was essentially a direct payment for the possession of various categories of animals and these were linked to a land resource base. The Agenda 2000 reform consists in a further price decrease associated with an increase in direct payments. The objective of this paper is to assess how the behaviour of beef producers is sensitive to changes in production prices and to changes in premiums. The analysis relies on an analytical framework which allows to take into account the dynamic feature of beef production and the subsidies provided by the Common Agricultural Policy. We studys how the beef supply response is modified when various exogenous variables like prices or premiums are changed. The application focuses on the dynamics of beef supply response in the French beef sector.
