Work is changing. Speed and flexibility are more in demand than ever before thanks to an accelerating knowledge economy and sophisticated communication networks. These changes have forced a mass rethinking of the way we coordinate, collaborate, and communicate. Instead of projects coming to established teams, teams are increasingly converging around projects. These "e;all-edge adhocracies"e; are highly collaborative and mostly temporary, their edge coming from the ability to form links both inside and outside an organization. These nimble groups come together around a specific task, recruiting personnel, assigning roles, and establishing objectives. When the work is done they disband their members and take their skills to the next project.Spinuzzi offers for the first time a comprehensive framework for understanding how these new groups function and thrive. His rigorous analysis tackles both the pros and cons of this evolving workflow and is based in case studies of real all-edge adhocracies at work. His provocative results will challenge our long-held assumptions about how we should be doing work.

The subject of murder has always held a particular fascination for us. But, since at least the nineteenth century, we have seen the murderer as different from the ordinary citizen-a special individual, like an artist or a genius, who exists apart from the moral majority, a sovereign self who obeys only the destructive urge, sometimes even commanding cult followings. In contemporary culture, we continue to believe that there is something different and exceptional about killers, but is the murderer such a distinctive typeAre they degenerate beasts or supermen as they have been depicted on the page and the screenOr are murderers something else entirely?In The Subject of Murder, Lisa Downing explores the ways in which the figure of the murderer has been made to signify a specific kind of social subject in Western modernity. Drawing on the work of Foucault in her studies of the lives and crimes of killers in Europe and the United States, Downing interrogates the meanings of media and texts produced about and by murderers. Upending the usual treatment of murderers as isolated figures or exceptional individuals, Downing argues that they are ordinary people, reflections of our society at the intersections of gender, agency, desire, and violence.

Puericultur? ?i pediatrie pentru asisten?i medicali ofer? elevilor ?colilor postliceale sanitare un instrument de studiu al particularit??ilor fiziologice ?i patologice ale copilului, necesar identific?rii nevoilor fundamentale ale copilului s?n?tos ?i bolnav ?i aplic?rii tehnicilor specifice de ?ngrijire a acestuia.Aceast? carte se dore?te a fi un ghid teoretic pentru elevii ?i asisten?ii medicali care ?ngrijesc copii ?n diverse perioade de dezvoltare, pornind de la premisa c? un copil nu este un adult ?n miniatur?.Lucrarea este astfel conceput? ?nc?t informa?ia oferit? s? acopere cerin?ele programei analitice, s? fie simplu de accesat ?i s? fie u?or de ?n?eles.

Se spune c? ?nceputurile pot fi uneori ca o cea?? de nep?truns. A?a este ?i cazul acestei pove?ti, care ?ncepe cu apari?ia unei noi specii, probabil ?n urm? cu dou? mii de ani. Specia nu are ?nc? un nume – nimic nu are ?nc? unul – dar are capacitatea de a numi lucruri.Asemenea oric?rei alte noi specii, starea acesteia este fragil?. Num?rul membrilor s?i este mic, iar teritoriul pe care ?l ocup? este redus la o bucat? din estul Africii. Popula?ia sa cre?te treptat, dar apoi, destul de probabil, aceasta se diminueaz? din nou – unii ar spune c? asta se ?nt?mpl? ?ntr-un mod aproape fatal – ajung?nd la doar c?teva mii de perechi.Membrii speciei nu sunt neap?rat foarte rapizi sau puternici sau fertili. Ei sunt ?ns? nemaipomenit de descurc?re?i. Progresiv, ei ?ncep s? exploreze teritorii cu diferite climate, diferi?i pr?d?tori ?i diferite tipuri de v?nat. Nici una dintre constr?ngerile aduse de habitat sau de geografia locului nu pare s? ?i afecteze prea tare.

Medicina modern? a f?cut progrese imense. Cu toate acestea, nu a reu?it s? ?nving? cancerul, boala nemiloas? care face milioane de victime ?n fiecare an, la nivel mondial. ?i totu?i, dr. Max Gerson (1881-1959) ne-a oferit o raz? de speran??, prin terapia alternativ? care ?i poart? numele. ?n 1958, el a fost primul medic din lume care a spus despre cancer c? ar fi cauzat de mai mul?i factori independen?i. Dintre cei 49 de astfel de factori identifica?i p?n? ?n prezent (deficien?ele de nutri?ie, radia?iile de diverse tipuri, ingerarea aditivilor alimentari, stresul cronic, consumul de tutun ?i de alcool etc.), ?n mod surprinz?tor, alimentele toxice fac cel mai mare r?u. Peste 70% dintre tumorile maligne sunt cauzate, ?ntr-un fel sau altul, de ceea ce m?nc?m. Tocmai de aceea, Terapia Gerson are la baz? o diet? care include fructe ?i legume proaspete, cultivate organic, ?i 13 pahare de sucuri proaspete pe zi, la intervale fixe. Dup? 70 de ani de la apari?ia terapiei, timp ?n care mii de pacien?i au fost trata?i cu succes, fiica dr. Gerson, Charlotte, ea ?ns??i terapeut ?n medicina alternativ?, ?mpreun? cu dr. Morton Walker ofer? ?i mai multe informa?ii despre efectele puternice de vindecare ale fructelor ?i legumelor organice. Afl?: cum s? ?nvingi cancerul schimb?nd chimia organismului;cum s? prepari sucuri prin tehnici speciale pentru a le maximiza puterea de vindecare;cum s? scapi de alergii, obezitate, hipertensiune, SIDA, lupus ?i alte boli;ce suplimente ?nt?resc sistemul imunitar. Terapia Gerson – cea mai bun? metod? pentru oricine a spus vreodat? ?Vreau s? m? fac bine. Ar?ta-mi cum“ A func?ionat ?i pentru al?ii, va func?iona ?i pentru tine! ?nvinge boala cu ajutorul Terapiei Gerson!

The great World War was more than two-thirds over when America entered the struggle, and yet in a sense this country was in the war from its very beginning. Three great inventions controlled the character of the fighting and made it different from any other the world has ever seen. These three inventions were American. The submarine was our invention; it carried the war into the sea. The airplane was an American invention; it carried the war into the sky. We invented the machine-gun; it drove the war into the ground. It is not my purpose to boast of American genius but, rather, to show that we entered the war with heavy responsibilities. The inven-tions we had given to the world had been developed marvelously in other lands. Furthermore they were in the hands of a determined and unscrupulous foe, and we found before us the task of overcoming the very machines that we had created. Yankee ingenuity was faced with a real test. The only way of overcoming the airplane was to build more and better machines than the enemy possessed. This we tried to do, but first we had to be taught by our allies the latest refinements of this machine, and the war was over before we had more than started our a?rial program. The machine-gun and its accessory, barbed wire (also an American invention), were overcome by the tank; and we may find what little comfort we can in the fact that its invention was inspired by the sight of an American farm tractor. But the tank was a British creation and was undoubtedly the most important invention of the war. On the sea we were faced with a most baffling problem. The U-boat could not be coped with by the building of swarms of submarines. The essential here was a means of locating the enemy and destroying him even while he lurked under the surface. Two American inventions, the hydrophone and the depth bomb, made the lot of the U-boat decidedly unenviable and they hastened if they did not actually end German frightfulness on the sea. But these were by no means the only inventions of the war. Great Britain showed wonderful ingenuity and resourcefulness in many di-rections; France did marvels with the airplane and showed great clev-erness in her development of the tank and there was a host of minor inventions to her credit; while Italy showed marked skill in the crea-tion of large airplanes and small seacraft.

Men's heads are by no means all like to one another, nor are the sutures of the head of all men constructed in the same form. Thus, whoever has a prominence in the anterior part of the head (by prominence is meant the round protuberant part of the bone which projects beyond the rest of it), in him the sutures of the head take the form of the Greek letter tau, T; for the head has the shorter line running transverse before the prominence, while the other line runs through the middle of the head, all the way to the neck.

sszefoglaló knyvem olyan témát mutat be, amivel már tbb ismeretterjeszt írásban találkozhatott az olvasó, ám ezúttal olyan részletekkel és érdekességekkel találkozunk, amit eme knyvek alig, vagy egyáltalán nem taglalnak. E szerzeményben végigkvetjük a Fld mélyérl induló izzó anyagot, a kérgen át a felszínig, ahol tüzet és pusztítást zúdít mindenre és mindenkire a kzelben. Bemutatom, hogy mi lesz a kihlt lávából, és milyen formákat hoz létre. Ezen külnleges természeti képzdmények kialakulását és fejdését vesszük górcs alá. Megismerkedünk pár külnleges tzhányóval, amik pusztításuk révén rendkívüli hatással voltak nemcsak krnyezetükre, hanem az emberiségre is. Olyan ismereteket mutatunk be, amelyek meglepetést okozhatnak az olvasóknak.

The electrical problems of the present day lie largely in the economical transmission of power and in the radical improvement of the means and methods of illumination. To many workers and thinkers in the domain of electrical invention, the apparatus and devices that are familiar, appear cumbrous and wasteful, and subject to severe limitations. They believe that the principles of current generation must be changed, the area of current supply be enlarged, and the appliances used by the consumer be at once cheapened and simplified. The brilliant successes of the past justify them in every expectancy of still more generous fruition.??The present volume is a simple record of the pioneer work done in such departments up to date, by Mr. Nikola Tesla, in whom the world has already recognized one of the foremost of modern electrical in-vestigators and inventors. No attempt whatever has been made here to emphasize the importance of his researches and discoveries. ??Great ideas and real inventions win their own way, determining their own place by intrinsic merit. But with the conviction that Mr. Tesla is blazing a path that electrical development must follow for many years to come, the compiler has endeavored to bring together all that bears the impress of Mr. Tesla's genius, and is worthy of preservation. Aside from its value as showing the scope of his inventions, this volume may be of service as indicating the range of his thought. There is intellectual profit in studying the push and play of a vigorous and original mind.?

A volume on the nature, ingredients, causes and consequences of human happiness by the father and son team of Anthony and Charles Kenny.

On the Origin of Species, published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology. Its full title was On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life. For the sixth edition of 1872, the short title was changed to The Origin of Species. Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation. Various evolutionary ideas had already been proposed to explain new findings in biology. There was growing support for such ideas among dissident anatomists and the general public, but during the first half of the 19th century the English scientific establishment was closely tied to the Church of England, while science was part of natural theology. Ideas about the transmutation of species were controversial as they conflicted with the beliefs that species were unchanging parts of a designed hierarchy and that humans were unique, unrelated to other animals. The political and theological implications were intensely debated, but transmutation was not accepted by the scientific mainstream. The book was written for non-specialist readers and attracted widespread interest upon its publication. As Darwin was an eminent scientist, his findings were taken seriously and the evidence he presented generated scientific, philosophical, and religious discussion. The debate over the book contributed to the campaign by T. H. Huxley and his fellow members of the X Club to secularise science by promoting scientific naturalism. Within two decades there was widespread scientific agreement that evolution, with a branching pattern of common descent, had occurred, but scientists were slow to give natural selection the significance that Darwin thought appropriate. During the "eclipse of Darwinism" from the 1880s to the 1930s, various other mechanisms of evolution were given more credit. With the development of the modern evolutionary synthesis in the 1930s and 1940s, Darwin's concept of evolutionary adaptation through natural selection became central to modern evolutionary theory, and it has now become the unifying concept of the life sciences. Summary of Darwin's theory: Darwin's theory of evolution is based on key facts and the inferences drawn from them, which biologist Ernst Mayr summarised as follows: ? Every species is fertile enough that if all offspring survived to reproduce the population would grow (fact).? Despite periodic fluctuations, populations remain roughly the same size (fact).? Resources such as food are limited and are relatively stable over time (fact).? A struggle for survival ensues (inference).? Individuals in a population vary significantly from one another (fact).? Much of this variation is inheritable (fact).? Individuals less suited to the environment are less likely to survive and less likely to reproduce; individuals more suited to the environment are more likely to survive and more likely to reproduce and leave their inheritable traits to future generations, which produces the process of natural selection (inference).? This slowly effected process results in populations changing to adapt to their environments, and ultimately, these variations accumulate over time to form new species (inference).

Lunacy, the legendary notion of minds unhinged by the moon, continues to captivate the popular imagination. Although it violates the assumptions of modern science and psychiatry, such belief remains common among mental health workers. Furthermore, several studies have found a small, unexplained correlation between behaviour and the lunar cycle. The book is divided into two parts. It begins with a historical account of the lunacy concept, followed by an investigation of hypothetical mechanisms for a lunar effect.

I shall be grateful to any Reader of this book who will point out any mistakes or misprints he may happen to notice in it, or any passage which he thinks is not clearly expressed. I have a quantity of MS. in hand for Parts II and III, and hope to be able——should life, and health, and opportunity, be granted to me, to publish them in the course of the next few years. Their contents will be as follows:— PART II. ADVANCED.Further investigations in the subjects of Part I. Propositions of other forms (such as “Not-all x are y”). Triliteral and Multiliteral Propositions (such as “All abc are de”). Hypotheticals. Dilemmas. &c. &c. Part III. TRANSCENDENTAL.Analysis of a Proposition into its Elements. Numerical and Geometrical Problems. The Theory of Inference. The Construction of Problems. And many other Curiosa Logica. Introduction TO LEARNERS.[N.B. Some remarks, addressed to Teachers, will be found in the Appendix]The Learner, who wishes to try the question fairly, whether this little book does, or does not, supply the materials for a most interesting mental recreation, is earnestly advised to adopt the following Rules:— (1) Begin at the beginning, and do not allow yourself to gratify a mere idle curiosity by dipping into the book, here and there. This would very likely lead to your throwing it aside, with the remark “This is much too hard for me!”, and thus losing the chance of adding a very large item to your stock of mental delights. This Rule (of not dipping) is very desirable with other kinds of books——such as novels, for instance, where you may easily spoil much of the enjoyment you would otherwise get from the story, by dipping into it further on, so that what the author meant to be a pleasant surprise comes to you as a matter of course. Some people, I know, make a practice of looking into Vol. III first, just to see how the story ends: and perhaps it is as well just to know that all ends happily——that the much-persecuted lovers do marry after all, that he is proved to be quite innocent of the murder, that the wicked cousin is completely foiled in his plot and gets the punishment he deserves, and that the rich uncle in India (Qu. Why in India? Ans. Because, somehow, uncles never can get rich anywhere else) dies at exactly the right moment——before taking the trouble to read Vol. I. This, I say, is just permissible with a novel, where Vol. III has a meaning, even for those who have not read the earlier part of the story; but, with a scientific book, it is sheer insanity: you will find the latter part hopelessly unintelligible, if you read it before reaching it in regular course. (2) Don’t begin any fresh Chapter, or Section, until you are certain that you thoroughly understand the whole book up to that point, and that you have worked, correctly, most if not all of the examples which have been set. So long as you are conscious that all the land you have passed through is absolutely conquered, and that you are leaving no unsolved difficulties behind you, which will be sure to turn up again later on, your triumphal progress will be easy and delightful. Otherwise, you will find your state of puzzlement get worse and worse as you proceed, till you give up the whole thing in utter disgust. (3) When you come to any passage you don’t understand, read it again: if you still don’t understand it, read it again: if you fail, even after three readings, very likely your brain is getting a little tired. In that case, put the book away, and take to other occupations, and next day, when you come to it fresh, you will very likely find that it is quite easy.(4) If possible, find some genial friend, who will read the book along with you, and will talk over the difficulties with you. Talking is a wonderful smoother-over of difficulties. When I come upon anything——in Logic or in any other hard subject——that entirely puzzles me, I find it a capital plan to talk it over, aloud. ? ? ? ? ? L. C.29, Bedford Street, Strand.
