The history of but few insects can be compared with that ofPectinophora(Geleckia)gossypiella, which, having started as a minor pest in its native country and having been transported by human agency to a new country, has there suddenly leapt to the most important position as a major pest of the crop it attacks. In this respect it may be placed with thePhylloxeraand the gipsy moth.Although the chief object of this paper is to consider certain aspects of the damage done by the pink bollworm to the cotton crop, the following short summary of the established facts concerning the life-history of the insect may be useful to readers not familiar with its habits.Food-Plants. The pink bollworm feeds on cotton (Gossypium, various species), okra (Hibiscus esculentus; Arabic :bamia; Hindustani :bhindi), Deccan hemp (Hibiscus cannabinus; Arabic :til), hollyhock (Althaea rosea), mallow (Malvasp., probablysilvestris),Thespesia populnea(fideFullaway ; this record is considered doubtful by Busck), andAbutilonsp. (Arabic :hanbuk;fideKing).It will be noticed that all these plants belong to the Malvaceae. The record for pomegranates given by Dudgeon and Gough is without doubt due to error.Of all these food-plants cotton is preferred. The larvae attack the stems (feeding in the cambium and boring a tunnel which encircles the stem), flowers, flower-buds, bolls and seeds.

“Arminianism” was the subject of important theological controversies in the seventeenth and eighteenth centuries, and it maintains an important position within Protestant thought. What became known as “Arminian” theology was held by people across a swath of geographical and ecclesial positions; it developed in European, British, and American contexts, and it engaged with a wide range of intellectual challenges. While standing together in their common rejection of several key planks of Reformed theology, proponents of Arminianism took various positions on other matters. Some were broadly committed to catholic and creedal theology; others were more open to theological revision. Some were concerned primarily with practical concerns; others were engaged in system building as they sought to articulate and defend an overarching vision of God and the world. The story of this development is both complex and important for a proper understanding of the history of Protestant theology. However, this historical development of Arminian theology is not well known. In this book, Thomas H. McCall and Keith D. Stanglin offer a historical introduction to Arminian theology as it developed in modern thought, providing an account that is based upon important primary sources and recent secondary research that will be helpful to scholars of ecclesial history and modern thought as well as comprehensible and relevant for students.

Open Air Markets

Abstract Background Open air markets hold an important position for ethnobiologists. In Southeast Asia, they are seriously understudied, in spite of their incredible biocultural diversity. In order to fill this gap we recorded plants and fungi sold in the open air markets of Luang Prabang, Lao PDR. Methods The markets were visited 38 times in four seasons: the dry season, early monsoon, mid-monsoon, and end-of-monsoon, at least 8 times per season. All items were photographed and voucher specimens were collected. Fungi were identified using DNA barcoding techniques. Results We recorded 110 species of wild edible plants and 54 species of fungi, including 49 wild-collected species. The sold plants included 86 species of green vegetables, 18 species of fruits and 3 species of flowers. Products from woody species constitute around half of all taxa sold. These include the young shoots of tree leaves, which are used for salads—an interesting feature of Lao cuisine. A large number of extremely rare Russula, with no reference sequences represented in databases or even species unknown to science is present on sale in the markets. Conclusions Luang Prabang markets are some of the richest in species of wild edible plants and fungi in Asia, and indeed in the whole world. It is worth pointing out the exceptionally long list of wild edible mushrooms which are sold in Luang Prabang (and probably elsewhere in Laos). We view the Morning Market of Luang Prabang as a cultural treasure that unites the traditions of eating a large number of living species with very diverse flora and fauna. Measures should be taken to strike a balance between local foraging traditions and nature conservation priorities.

For French Renaissance architecture no single building occupies a more important position than that of the Chateau du Louvre. This fact long has been recognized and the Louvre has become the example of French architecture of this period in all surveys of architecture. Little attention, however, has been paid to the role of the Louvre in the history of Renaissance architecture generally or to its place in the yet to be written history of the palace type. However, before these latter objectives may be attained a clarification of the problems involved in the actual construction of the Louvre during its initial phases in the Renaissance is necessary.

The contractile history of muscle can potentiate electrically evoked force production. A link to voluntary force production, related in part to an increase in reflex excitability, has been suggested.Purpose:Our purpose was to quantify the effect of postactivation potentiation on voluntary force production and spinal H-reflex excitability during explosive plantar fexion actions.Methods:Plantar flexor twitch torque, soleus H-reflex amplitudes, and the rate of force development of explosive plantar fexion were measured before and after 4 separate conditioning trials (3 × 5 s maximal contractions).Results:Twitch torque and rate of force production during voluntary explosive plantar flexion were significantly increased (P < .05) while H-reflex amplitudes remained unchanged. Although twitch torque was significantly higher after conditioning, leading to a small increase in the rate of voluntary force production, this was unrelated to changes in reflex excitability.Conclusion:We conclude that postactivation potentiation may result in a minor increase in the rate of voluntary isometric force production that is unrelated to neural excitability.

This book explores the development of Scottish child protection law from its earliest days in the poor law, tracing the changing assumptions that underlay child protection processes, and the radical shift of emphasis from private (charitable) endeavour to public (local authority) duty. This book looks at the developing legal processes for removing children from abusive or neglectful environments, explores how child offenders and child victims came to be dealt with in the same processes, and examines the reasons why Scots law has managed to continue to cleave its own procedural path in the contemporary world. It explores both processes and outcomes, explaining how the juvenile court evolved into the children’s hearing, and it examines the substantive continuities between the various orders that could be made over children. The regulation of boarding out and fostering of children is compared with the regulation of institutional care, and the evolution of aftercare provisions is explained. The book also offers an analysis of the (dubious) legal basis for the Imperial practice of sending troubled children to the colonies, as part of a deliberate policy of spreading British “stock” across the world. The final chapter traces the origins and statutory control of the practice of adoption of children, from its days as an informal arrangement through its early manifestation as a minor action changing status to its present position as the most radical order that a court of law can make.

Abstract Whenever one reads internal histories of psychology what is covered is the establishment of a lab by Wundt in 1879 as the initiating act and then the breakaway movements of the 20th Century are discussed: Behaviorism, Gestalt Theory, Psychoanalysis, and most recently the Cognitive revival. However, Aron Gurwitsch described a perspective noted by Cassirer and first developed by Malebranche, which dates the founding of psychology at the same time as that of physics in the 17th Century. This external perspective shows the dependency of psychology upon the concepts, methods and procedures of physics and the natural sciences in general up until the present time. Gurwitsch argues that this approach has blocked the growth of psychology and has assured its status as a minor science. He argued that the everyday Lifeworld achievements of subjectivity are the true subject matter of psychology and that a phenomenological approach to subjectivity could give psychology the authenticity it has been forever seeking but never finding as a naturalistic science. Some clarifying thoughts concerning this phenomenologically grounded psychology are offered, especially the role of desire. The assumption of an external perspective toward the history of psychology fostered the insights about psychology’s scientific role.

André Martinet holds an important position in the history of linguistics in the twentieth century. For more than six decades he decisively influenced the development of linguistics in France and in the world. He is one of the spokespersons for French linguistic structuralism, the structuralisme fonctionnel. The article focuses on a description and critical appreciation of the interlinguistic part of Martinet’s work. The issue of auxiliary languages and hence interlinguistics had interested Martinet greatly from his youth and provoked him to examine the matter actively. From 1946 onwards he worked in New York as a professor at Columbia University and a research director of the International Auxiliary Language Association (IALA). From 1934 he was in contact with the Danish linguist and interlinguist Otto Jespersen (1860–1943). Martinet, who went back to Paris in 1955 to work as a professor at the École Pratique des Hautes Études (Sorbonne), increasingly developed into an expert in planned languages; for his whole life, he was committed to the world-wide use of a foreign language that can be learned equally easily by members of all ethnic groups; Esperanto, functioning since 1887, seemed a good option to him.

Ancient Geography

The appearance in 1998 of F. E. Romer's English translation of Pomponius Mela's De Chorographia has helped to raise further the profile of this previously rather obscure author. Indeed, since the publication a decade previously of the Budé edition by Alain Silberman, interest in Mela seems to have grown quite steadily. Important contributions in German by Kai Brodersen have widened our appreciation of Mela's place within ancient geography as a whole, and his role within the history of cartography has been the subject of a number of shorter pieces.One element common to all these works, however, is a continuing tendency to disparage both Mela himself and the work he created. This is typified by Romer, for whom Mela was ‘a minor writer, a popularizer, not a first-class geographer’; one ‘shocking reason’ for his choice of genre was simply poor preparation, ‘insufficient for technical writing in geography’. Similar judgements appear in the works of Brodersen and Silberman. Mela's inaccuracies are, for these critics, typical of the wider decline of geography in the Roman period. Perhaps such negative views sprang initially from a sense of frustration: it was counted as one of our author's chief defects that he failed to list many sources for his work. For scholars interested in Quellenforschung it makes poor reading. Yet, quite clearly, the De Chorographia has also been damned by comparison. Mela's work has been held against the best Graeco-Roman learning on geography during antiquity—against Strabo, Ptolemy, or Pliny—and it has usually been found wanting. Set against the achievements of his peers, his work does not stand close scrutiny. Thus, for most scholars, the text has been read as a failed exercise in technical geography, or a markedly inferior document in the wider Graeco-Roman geographical tradition.

Major Pest

The mysterious extinction of the Rocky Mountain Grasshopper, Melanoplus spretus, a major pest species on the prairies and plains of the 1800s, is truly a remarkable event in the history of agriculture. Recently, we obtained specimens of M. spretus from museums and from 400-year-old glacial deposits in Wyoming. We report success in obtaining mitochondrial DNA sequences from both sources. This permitted us to examine two issues surrounding the species’ disappearance. First, a long-standing view that M. spretus and the extant species Melanoplus sanguinipes are (if not phase transforms of one another) sister taxa, is disputed, but cannot be rejected with certainty. Interestingly, there is some evidence that suggests there may be a closer affinity with another member of the Mexicanus species-group, Melanoplus bruneri. Second, because M. spretus still possesses considerable nucleotide diversity (1.15 ± 0.19%), a depletion of variation cannot be considered a factor contributing to its demise.
