An important question for bacterial cell division is how the invaginating septum can overcome the turgor force generated by the high osmolarity of the cytoplasm. I suggest that it may not need to. Several studies in Gram‐negative bacteria have shown that the periplasm is isoosmolar with the cytoplasm. Indirect evidence suggests that this is also true for Gram‐positive bacteria. In this case the invagination of the septum takes place within the uniformly high osmotic pressure environment, and does not have to (...) fight turgor pressure. A related question is how the V‐shaped constriction of Gram‐negative bacteria relates to the plate‐like septum of Gram‐positive bacteria. I collected evidence that Gram‐negative bacteria have a latent capability of forming plate‐like septa, and present a model in which septal division is the basic mechanism in both Gram‐positive and Gram‐negative bacteria.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

The eukaryotic cytoskeleton appears to have evolved from ancestral precursors related to prokaryotic FtsZ and MreB. FtsZ and MreB show 40–50% sequence identity across different bacterial and archaeal species. Here I suggest that this represents the limit of divergence that is consistent with maintaining their functions for cytokinesis and cell shape. Previous analyses have noted that tubulin and actin are highly conserved across eukaryotic species, but so divergent from their prokaryotic relatives as to be hardly recognizable from sequence comparisons. One (...) suggestion for this extreme divergence of tubulin and actin is that it occurred as they evolved very different functions from FtsZ and MreB. I will present new arguments favoring this suggestion, and speculate on pathways. Moreover, the extreme conservation of tubulin and actin across eukaryotic species is not due to an intrinsic lack of variability, but is attributed to their acquisition of elaborate mechanisms for assembly dynamics and their interactions with multiple motor and binding proteins. A new structure‐based sequence alignment identifies amino acids that are conserved from FtsZ to tubulins. The highly conserved amino acids are not those forming the subunit core or protofilament interface, but those involved in binding and hydrolysis of GTP.

This is an elegant and clear tour through many of the issues in philosophy of mind that have occupied philosophers of this century. The topics covered include the problem of other minds, arguments for and against the existence of the soul, a discussion of the bundle theory of the mind, behaviorism, functionalism, mind/brain identity, the argument against the possibility of private language, personal identity and the possibility of after-life, and the question of whether animals and computers can have minds. Carruthers (...) emphasizes arguments for and against the various theories considered, and encourages readers to actively evaluate these approaches as well. Written with clarity and directness, Introducing Persons will prove a useful text for the beginner while simultaneously providing original material of interest to the advanced student and professional philosopher.

In lieu of an abstract, here is a brief excerpt of the content:Frederick J. Streng Book Award:An Interview with Harold Kasimow, John Keenan, and Linda KeenanHarold Kasimow, John P. Keenan, and Linda Klepinger KeenanThe recipient of the Frederick J. Streng Book of the Year Award for 2004 is Beside Still Waters: Jews, Christians, and the Way of the Buddha, edited by Harold Kasimow, John P. Keenan, and Linda Klepinger Keenan. This book provides the reader with a combination of (...) reflection on the creatively transformative power of interreligious dialogue and documentation of that creative transformation in the lives of committed Jews and Christians in dialogue with Buddhism. The bulk of this book consists of candid, autobiographical essays by seven Jewish and Christian scholars in the form of personal testimony, which, taken as a whole, presents an extended argument for the value of interfaith dialogue in general and Buddhist-Christian-Jewish dialogue in particular. The final section of the book consists of four essays written from sociological, Jewish, Christian, and Buddhist perspectives by authors who have read the primary essays and reflect on interreligious dialogue more broadly in light of their own particular experience and research.Those who read Beside Still Waters as seekers will find themselves in the company of fellow pilgrims on the Way who offer their particular life stories filled with focused insight and theological sophistication. The strength of this collection of essays is that it robustly displays Jewish and Christian encounter with Buddhism as a new direction that contemporary Buddhist-Christian dialogue as practiced within the Society for Buddhist-Christian Studies would do well to emulate.Buddhist-Christian Studies asked the editors a few questions.Buddhist-Christian Studies: Why did you write Beside Still Waters?John Keenan: Because Harold and I wanted to write a book together. Each of us is much involved in our own tradition as well as in the study and practice of Buddhism, and we wanted to show that this kind of encounter with another religious tradition does not mutate one's own identity. For this reason, we wanted contributors to speak out of their personal experience rather than to address the philosophical and doctrinal issues that are engendered by such interfaith encounters—although these issues should of course be addressed elsewhere.Harold Kasimow: Perhaps the following Hassidic tale best answers this question: "Rabbi Eizik, son of Rabbi Yekel, travels to Prague in search of treasure. He ultimately discovers, after meeting with a Christian, that the treasure is in fact buried [End Page 205] at his family's home back in Krakow. Thus it is a Christian who helps Rabbi Eizik to find the treasure in Judaism, to perceive more profoundly the depth and uniqueness of the Jewish tradition." This has been my own experience and is the reason why I was interested in writing this book together with people with whom I have a very strong karmic connection.Was it difficult to solicit and edit the contributors' essays?Linda Keenan: Not at all. With only one exception, everyone we contacted agreed to write an essay for the book. In one or two instances, we pushed for something more personal than was first submitted, and we were very pleased with the final collection.How did the three of you work together?HK: I often spoke to Linda over the phone, and John could speak to her in person, and Linda did all the work.LK: Harold and John conceived the idea and contacted potential contributors. The three of us consulted a great deal over the telephone and by e-mail. And Harold kept us on task at each stage of the book and has been its greatest promoter.JK: The above is accurate, but the book was written by the contributors.Is there anything you would have done differently if you could do it over? Any contributors you missed this time for one reason or another that you would recruit for a new edition?LK: We would not change what we did, but there are certainly many more Jews and Christians who could make excellent contributions to a new edition of the book. In fact, the most difficult thing was knowing so many people—including, among others, most of the membership of the... (shrink)

While citizens often use non-instrumental arguments to support environmental protection, most governmental policies are justified by instrumental arguments. This paper explores some of the reasons. We interviewed senior policy advisors to four European governments active in global climate change negotiations and the UNCED (United Nations Conference on Environment and Development) process. In response to our questions, a majority of these advisors articulated deeply held personal environmental values. They told us that they normally keep these values separate from their professional environmental (...) policy activities. We interpret these findings within the context of the literature on environmental ethics and values. We suggest that environmental policy could be improved if widely held environmental values were articulated, validated, and admitted into the process of policy analysis and deliberation. (shrink)

Many adoptees face a number of challenges relating to separation from biological parents during the adoption process, including issues concerning identity, intimacy, attachment, and trust, as well as language and other cultural challenges. One common health challenge faced by adoptees involves lack of access to genetic-relative family health history. Lack of GRFHx represents a disadvantage due to a reduced capacity to identify diseases and recommend appropriate screening for conditions for which the adopted person may be at increased risk. In this (...) article, we draw out common features of traditionally understood “health disparities” in order to identify analogous features in the context of adoptees’ lack of GRFHx. (shrink)
