...Antonie van Leeuwenhoek81: 537–547, 2002. © 2002Kluwer Academic Publishers. Printed in the Netherlands. 537 Antibiotic production by bacterial biocontrol agents Jos M. Raaijmakers ∗ , Maria Vlami & Jorge T. de Souza Department of Plant Sciences, Laboratory of Phytopathology, Wageningen University, Binnenhaven 5, 6709 PG Wageningen, The Netherlands (∗ Author for correspondence) Abstract Interest in biological control of plant pathogens has been stimulated in recent years by trends in agriculture to-wards greater sustainability and public concern about the use of hazardous pesticides. There is now unequivocal evidence that antibiotics play a key role in the suppression of various soilborne plant pathogens by antagonistic microorganisms. The significance of antibiotics in biocontrol, and more generally in microbial interactions, often has been questioned because of the indirect nature of the supporting evidence and the perceived constraints to an-tibiotic production in rhizosphere environments. Reporter gene systems and bio-analytical techniques have clearly demonstrated that antibiotics are produced in the spermosphere and rhizosphere of a variety of host plants. Several abiotic factors such as oxygen, temperature, specific carbon and nitrogen sources, and microelements have been identified to influence antibiotic production by bacteria biocontrol agents. Among the biotic factors that may play a determinative role in antibiotic production are the plant host, the...

...The Cathedral and the Bazaar Eric Steven Raymond cf text and copyright at: www.tuxedo.org/~esr/writings Abstract I anatomize a successful open-source project, fetchmail, that was run as a deliberate test of some surprising theories about so=ware engineering suggested by the history of Linux. I discuss these theories in terms of two fundamentally di:erent development styles, the “cathedral” model of most of the commercial world versus the “bazaar” model of the Linux world. I show that these models derive from opposing assumptions about the nature of the so=ware-debugging task. I then make a sustained argument from the Linux experience for the proposition that “Given enough eyeballs, all bugs are shallow”, suggest productive analogies with other self-correcting systems of selfish agents, and conclude with some exploration of the implications of this insight for the future of so=ware. 1 The Cathedral and the Bazaar Linux is subversive. Who would have thought even five years ago (1991) that a world-class operating system could coalesce as if by magic out of part-time hacking by several thousand developers scattered all over the planet, connected only by the tenuous strands of the Internet? Certainly not I. By the time Linux swam onto my radar screen in early 1993, I had already been involved in Unix and open-source development for ten years. I was one of the first gnu contributors in the mid-1980s. I had released a good deal of open-source so=ware onto the net, developing...

With the excessive use of plastics and increasing pressure being placed on capacities available for plastic waste disposal, the need for biodegradable plastics and biodegradation of plastic wastes has assumed increasing importance in the last few years. Awareness of the waste problem and its impact on the environment has awakened new interest in the area of degradable polymers. The interest in environmental issues is growing and there are increasing demands to develop material which do not burden the environment significantly. Biodegradation is necessary for water-soluble or water-immiscible polymers because they eventually enter streams which can neither be recycled nor incinerated. It is important to consider the microbial degradation of natural and synthetic polymers in order to understand what is necessary for biodegradation and the mechanisms involved. This...

...WOMEN AND LEADERSHIP: THE STATE OF PLAY Deborah L. Rhode and Barbara Kellerman July, 2006 c Some four decades ago, Betty Friedan helped launch the contemporary women’s movement with her publication of The Feminine Mystique. The book famously identified a “problem that has no name”: American women’s confinement to a separate and unequal domestic sphere. One factor contributing to women’s unequal status was their absence from leadership positions. Another aspect of the problem was the lack of cultural consensus that this absence was itself part of the problem, and a matter of social concern. Over the last several decades, we have named that leadership problem and created a cottage industry to address it. Women’s underrepresentation in positions of power generates an increasing array of committees, commissions, consultants, centers, conferences, and commentary such as the essays that follow. Yet while we have made considerable progress in understanding the problem, we remain a dispiriting distance from solving it. I. The Underrepresentation of Women in Leadership Roles The facts are frustratingly familiar. Despite almost a half-century of equal opportunity legislation, women’s opportunities for leadership are anything but equal. To be sure, the situation has improved significantly over this period, particularly if leadership is broadly defined to include informal as well as formal exercises of authority.[i] By that definition, the percentage of women...

Question: Recognize a question or a problem. Hypothesis: An educated guess or a reasonable explanation. When the hypothesis can be tested by experiment, it qualifies as a scientific hypothesis Prediction: Consequences that can be observed if the hypothesis is correct.

Section one introduces what is international business and who has an interest in it. Students will sift through the globalization debate and understanding the impact of ethics on global businesses. Additionally, students will explore the evolution of international trade from past to present, with a focus on how firms and professionals can better understand today’s complex global business arena by understanding the impact of political and legal factors. The section concludes with a chapter on understanding how cultures are defined and the impact on business interactions and practices with tangible tips for negotiating across cultures. WHERE? Section two develops student knowledge about key facets of the global business environment and the key elements of trade and cooperation between nations and global organizations. Today, with increasing numbers of companies of all sizes operating internationally, no business or country can remain an island. Rather, the interconnections between countries, businesses, and institutions are inextricable. Even how we define the world is changing. No longer classified into simple and neat categories, the rapid changes within countries are redefining how global businesses think about developed, developing, and emerging markets.

...Preface A well-developed knowledge of clinical microbiology is critical for the practicing physician in any medical field. Bacteria, viruses, and protozoans have no respect for the distinction between ophthalmology, pediatrics, trauma surgery, or geriatric medicine. As a physician you will be faced daily with the concepts of microbial disease and antimicrobial therapy. Microbiology is one of the few courses where much of the "minutia" is regularly used by the practicing physician. This book attempts to facilitate the learning of microbiology by presenting the information in a clear and entertaining manner brimming with memory aids. Our approach has been to: 4) Create a conceptual, organized approach to the organisms studied so the student relies less on memory and more on logical pathophysiology. The text has been updated to include current information on rapidly developing topics, such as HIV and AIDS (vaccine efforts and all the new anti-HIV medications), Ebola virus, Hantavirus, E. coli outbreaks, Mad Cow Disease, and brand-new antimicrobial antibiotics. The mnemonics and cartoons in this book do not intend disrespect for any particular patient population or racial or ethnic group but are solely presented as memory devices to assist in the learning of a complex and important medical subject. We welcome suggestions for future editions. 1) Write in a conversational style for rapid assimilation. 2) Include numerous figures serving as "visual memory tools" and summary charts...
