An 18-year-old male presented with a 6-month history of paresthesia of both arms and legs after a minor neck trauma. CT scan revealed a partial aplasia of the anterior and posterior arches of the C1 vertebra resulting in a split atlas. MRI showed an intramedullary high-signal area. We performed a posterior decompressive laminectomy and occipitocervical fusion. The bony defect into the posterior arch was replaced by a connective tissue cord, resulting in a compression of the dural sheath. The symptoms recovered completely 1 month after surgery. Knowledge of this rare malformation is crucial to the correct management of these cases.

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.

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.

В статье представлены результаты исследования, цель которого заключалась в оценке результативности Рязанских педагогических чтений как формы научной коммуникации с применением метода библиометрического анализа. Основными критериями анализа выступили структура массива публикаций в сборниках трудов конференции и структура массива цитирований трудов конференции. Распределение публикаций и их цитирований проведено с использованием в совокупности шести библиометрических индикаторов. Эмпирическую базу исследования составила подборка из 500 записей, сформированная путем поиска в РИНЦ и включившая статьи сборников конференции за период с 2015 по 2020 год. В результате библиометрического анализа была обнаружена «скачущая динамика» развития Рязанских педагогических чтений, раскрыта география научных связей данного мероприятия c наблюдаемым доминированием авторов-рязанцев, выявлен слабый эффект воздействия продуцируемого на этой конференции научного знания на развитие педагогических исследований и оценен ареал цитирования трудов конференции в научной периодике. The article presents the results of a research whose aim was to assess the effectiveness a scholarly conference Ryazan Pedagogical Readings through bibliometric assessment. The analysis encompasses such parameters as the corpus of articles published in the proceedings of the conference and citation index. The author employs six bibliometric indicators to assess the citation index and the publication rate. The research assesses 500 references cited within the Russian Science Citation Index database (conference proceedings of 2015–2020). Bibliometric analysis shows erratic dynamics in the history of Ryazan Pedagogical Readings, assesses the geography of research connections, reveals the prevalence of Ryazan researchers, detects a minor effect of the conference on the development of pedagogical research, performs citation analysis of journals.

The Matthew Creek Metamorphic Zone (MCMZ) exposes what is inferred to be the lowest structural level of the lower Aldridge Formation in the Canadian portion of the Belt–Purcell Supergroup. Zircon, monazite, and titanite were dated using the U–Pb system by LA–ICP–MS. The detrital zircon populations of quartzite layers in these rocks define a provenance dominated by sources of Laurentian affinity with a minor component of non-North American ages between 1600 and 1490 Ma. Special attention was paid to monazite in sillimanite-grade metapelitic schists that was analyzed using in situ LA–ICP–MS techniques guided by BSE imaging and compositional mapping. Textural and geochronological evidence indicate that coupled dissolution–reprecipitation affected detrital monazite at 1413 ± 10 Ma. This was followed by prograde monazite growth at 1365 ± 10 Ma, synchronous with crystallization of the nearby Hellroaring Creek peraluminous granite at 1365 ± 5 Ma. Late-stage pegmatite emplacement and ductile shearing along the contact of the MCMZ and overlying rocks occurred at 1335 ± 5 Ma, interpreted as a period of post-collisional extension, core complex formation, exhumation, and decompression melting. The entire package was subsequently affected by a pervasive ∼1050 Ma hydrothermal overprint that partially reset U–Pb dates in monazite, zircon, and titanite contained in all lithologies examined. The lowermost Belt–Purcell stratigraphy in southeast British Columbia preserves a detailed record of sedimentary provenance and a long history of episodic collision and extension that must be reconciled with plate reconstruction models for the break-up of the Nuna supercontinent and assembly of Rodinia.

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.

When Boston entered its pandemic lockdown in early March, it forced the cancellation of the Congregational Library's symposium “1620: New Perspectives on the Pilgrim Legacy.” With the cooperation of the director of the library, the Rev. Stephen Butler Murray, the four presenters—Carla Gardina Pestana, David Silverman, John G. Turner, and Francis Bremer—agreed to have the QUARTERLY publish revised versions of their talks with Kenneth P. Minkema as the guest editor of the papers. Far from seeing Plimoth as a minor backwater in the English settlement of Massachusetts, each of the essays situates the history of Plymouth Colony in more complex contexts: in its web of Atlantic connections, in the Indigenous identification of Anglo settlement as a cause of mourning, in its participation in the processes of enslavement, and in its larger impact upon the puritan, New England Way.

Gender archaeology has by now become a relatively well-established research topic within archaeology. Recent years have seen the publication of a number of edited volumes, a rapidly expanding number of papers, and even a few journals and newsletters dedicated to this subject. It is, therefore, very surprising that in this literature the historiographic analysis of women archaeologists has played only a minor part. Likewise they are hardly acknowledged in the ‘folk’ histories of the discipline (Lucy and Hill 1994: 2). The need to understand the disciplinary integration of women, to appreciate the varying socio-political contexts of their work, to reveal the unique tension between their roles as women and their academic lives, has become obvious and is strongly felt in many areas of the discipline. The insights yielded by such analysis will have significance at many levels and will be of paramount importance for the intellectual history of archaeology. In particular, such insights will necessitate a much-needed revision of disciplinary history by revealing its mechanisms of selecting and forgetting, and will play an important role in the analysis of archaeology’s knowledge claims. Histories of archaeology have broadly accepted, and spread, a perception of archaeology as being male-centred, both intellectually and in practice. These accounts, written by male archaeologists such as Glyn Daniel (1975), Alain Schnapp (1993), and Bruce Trigger (1989), are inevitably androcentric in their conceptualization and reconstruction of the disciplinary past. Their versions have, however, recently begun to be contested, as concern with critical historiography has grown, and a few explicit historiographical accounts of women archaeologists have appeared. So far, with regard to the role of women, the most extensive contributions are the edited volumes by Claassen (1994) and du Cros and Smith (1993). While providing an important beginning, these publications show that there is still a long way to go. In particular they demonstrate a gap in research coverage, as no investigation of the contribution of women outside the USA and Australia exists.
