description: Objectives: Asynchronous virtual learning communities provide learners with the ability to enhance their learning and contribute to their peers’ learning in a safe environment. However, the tone and content of learner comments, the level of engagement among learners, and the role of moderators have not been well studied within non-course-related virtual learning communities. Therefore, we sought to explore these characteristics using the NEJM Knowledge+ Question of the Week (NEJM Knowledge+ QoW) forum, a web-based asynchronous virtual learning community. Methods: We reviewed 73 NEJM Knowledge+ questions posted on the QoW forum between 2015 and 2016. We then selected three QoWs to analyze through a multistep coding process based on three broad criteria that aligned with our study aims. Results: Learner comments reflected both positive and critical tones, with learners sharing their own clinical practice and local experiences to contextualize their perspectives and reactions to both the QoW answer and the responses of other learners. Learners also commonly requested moderators to act as expert referees. Conclusion: Asynchronous virtual learning communities can engage learners by providing the opportunity to enhance their knowledge through responding to proposed medical scenarios and sharing their experiences in a discussion forum. Future work should examine the impact that geographic region has on asynchronous virtual learning communities and the role of moderators in shaping the learning experience.

description: Recent advances in natural-language processing and data analysis allow software bots to become virtual team members, providing an additional set of automated eyes and additional perspectives for informing and supporting teamwork. In this paper, we propose employing chatbots in the domain of software development with a focus on supporting analyses and measurements of teams' project data. The software project artifacts produced by agile teams during regular development activities, e.g. commits in a version control system, represent detailed information on how a team works and collaborates. Analyses of this data are especially relevant for agile retrospective meetings, where adaptations and improvements to the executed development process are discussed. Development teams can use these measurements to track the progress of identified improvement actions over development iterations. Chatbots provide a convenient user interface for interacting with the outcomes of retrospectives and the associated measurements in a chat-based channel that is already being employed by team members.

The transformation of the traditional Tongan polity : a genealogical consideration of Tonga's past
Creators: name: Herda, Phyllis S
Publisher: name: The Australian National University
Year: 1988
Subjects: subject: Tonga Politics and government
subject: Tonga History
subject: Tonga Genealogy

description: This study of traditional Tongan political history focuses on how Tongan genealogies and succession lists structure, and are structured by, cultural ideals and political processes. Their fluid nature as legitimizing charters of rank, authority and power is embraced in order to appreciate differing, and often contradictory, versions of Tongan history. The place of genealogies and succession lists in a Tongan construction of the past is explored and is incorporated in a history of not only individuals and events, but also of transformations of cultural processes, especially as they relate to Tongan notions of hereditary rank and chieftainship. The enduring and sacred nature of these notions is juxtaposed against the dynamics of status rivalry and the exercise of power. The record of both the enduring and dynamic forces, it is argued, is embedded in the genealogical traditions of Tonga. Consequently, the traditions are used as a focus point of the study: methodologically, in that they form a significant part of the source material, and stylistically, by providing a central structural theme to the thesis. The Prologue provides a geographical introduction to the Tongan archipelago, as well as Tonga’s relationship to the larger region of western Polynesia. Temporally, the study begins with the beginning of the Tongan universe and the divine chieftainship (Tu‘i Tonga) as expressed in the Tongan creation myth cycle (Chapter Two). Chapter Three chronicles the reigns of the early kau Tu ‘i Tonga and considers the successful challenge of their absolute authority by a ‘younger’ collateral lineage. This resulted in the creation of a bipartisan chieftainship of a sacred ruler (Tu‘i Tonga) and a secular ruler (Tu ‘i Ha‘atakalaua). The existence of early Tongan imperialism in western Polynesia is also investigated. Chapter Four explores the possibility of an extended period of exile for the Tu‘i Tonga in Samoa and the re-establishment of the title within Tonga. In addition, the successful challenge of the ruling secular title (Tu‘i Ha‘atakalaua) by a ‘younger’ collateral lineage, the establishment of the Tu ‘i Kanokupolu title as well as the proliferation of other chiefly titles which accompanied this challenge are considered. Internal rivalry between holders of the Tu ‘i Kanokupolu title and their ambitions to abolish the authority and status of the Tu‘i Tonga are dealt with in Chapter Five. Chapter Six focuses on the consolidation of secular rule, including the emergence of internal political struggles, after the denigration of the sacred ruler. Chapter Seven moves to a final consideration of the enduring nature of a sacred and hereditary Tongan chieftainship and its transformation rather than ultimate abolition.
BLM scale for the pion transition form factor

description: The NLO Brodsky-Lepage-Mackenzie (BLM) scale for the pion transition form factor has been determined. To achieve that, a consistent calculation up to nf-proportional NNLO contributions to both the hard-scattering amplitude and the perturbatively calculable part of the pion distribution amplitude has been performed. By combining and matching the results obtained for these two amplitudes, a proper cancellation of collinear singularities has been established and the gamma5 ambiguity problem (related to the use of the dimensional regularization method) has been resolved by using the naive-gamma5 as well as the 't Hooft-Veltman (HV) schemes. It has been demonstrated that the prediction for the pion transition form factor is independent of the factorization scale muF at every order in the strong coupling constant, making it possible to use the simplest choice muF^2=Q^2 at the intermediate steps of the calculation. Assuming the pion asymptotic distribution amplitude and working in the \bar{MS} scheme, we have found the BLM scale to be muR^2=muBLM^2 ~ Q^2/9. Based on the same distribution, the complete NLO prediction for the pion transition form factor has been calculated in the alphaV definition of the QCD coupling renormalized at muR^2=muV^2 = e^{5/3} muBLM^2 ~ Q^2/2. It is in good agreement with the presently available experimental data.

Not the way it really was : constructing the Tolai past
Creators: name: Neumann, Klaus
Publisher: name: The Australian National University
Year: 1988
Subjects: subject: Tolai (Melanesian people) History
subject: Papua New Guinea History

description: This study is an attempt to write a history of the colonial past of the Tolai in East New Britain, Papua New Guinea. The history consists of seven parts, each of them dealing with a particular theme or episode: the Toma killings in 1902 (chapter 1). prophecies of the arrival of the white people (chapter 3), the coming of the mission (chapter 5), the life history of Abaram ToBobo of Vunabalbal (chapter 7), early political organisation among Tolai men on Matupit and around Vunamami from the 1930s (chapter 9), images of the 'time of darkness' (chapter 11), and the alienation of Tolai land by Queen Emma and other planters in the late nineteenth century (chapter 13). The history uses European documentary sources and Tolai testimonies. The oral traditions and histories are used both as material to write a history and as elements of that history. The history draws also on observations made during twenty months of, fieldwork in Papua New Guinea. This study also attempts to analyse the way Tolai understand and use their past. In chapter 8 it is shown how the control of land is dependent on a control of the past. In chapters 10 and 12 it is demonstrated how customary exchanges guarantee a continuity between past and present, how customs change, and how customs become kastom. In chapters 3, 5 and 12, Tolci constructions of the past are compared with those of Tami and Kotte people. It is argued that a different pattern of colonisation changes the way people look at their past, and that the making of history has changed the production of histories. In chapter 6, I argue that academic oral historians need to recognise ora! histories and traditions as histories in their own right instead of using them only as sources to establish what really happened. In chapters 2, 4 and 14 some of the subjective premises of this history are presented when I talk about the history of this study, the concept and practice of fieldwork, and sketch a philosophy of history that is partly informed by Tolai constructions of their past. In the last chapter I suggest that the construction of the Tolai past needs to be a dialogue that is directed at knowing rather than knowledge.

More remarks on suppression of large black hole production in particle collisions

description: The problem of evaluating the cross section of production of large black holes in particle collisions at trans-Planckian energies is revisited. It is argued that the geometric cross section claimed in the literature would in fact lead to an exponentially growing with energy total cross section dominated by production of many "small" black holes. On the other hand, the semiclassical treatment of this problem, leading to an exponentially suppressed cross section for production of large black holes, requires that in the classical limit the cross section vanishes for massless colliding particles. The latter behavior can in principle be probed by numerical simulations in the classical general relativity.

description: We consider the production of a colourless system at next-to-leading order in the strong coupling constant $α_s$. We impose a transverse-momentum cutoff, qtcut, on the colourless final state and we compute the power corrections for the inclusive cross section in the cutoff, up to the fourth power. The study of the dependence of the cross section on qtcut allows for an understanding of its behaviour at the boundaries of the phase space, giving hints on the structure at all orders in $α_s$ and on the identification of universal patterns. The knowledge of such power corrections is also a required ingredient in order to reduce the dependence on the transverse-momentum cutoff of the QCD cross sections at higher orders, when the qt-subtraction method is applied. We present analytic results for both Drell--Yan vector boson and Higgs boson production in gluon fusion and we illustrate a process-independent procedure for the calculation of the all-order power corrections in the cutoff. In order to show the impact of the power-correction terms, we present selected numerical results and discuss how the residual dependence on qtcut affects the total cross section for Drell--Yan Z production and Higgs boson production via gluon fusion at the LHC.

Evangelical missionaries in the South Seas 1797-1860
Creators: name: Gunson, W.N.
Publisher: name: The Australian National University
Year: 1959

description: The work of missionaries has an important place in the history of the South Seas. Missions have played a significant role in directing much of the current thinking of the South Sea islanders, and the traditions of Christian teaching have become as fully a part of the ideological background as the traditions of their own culture Although the degree to which Christianity has affected the traditional ways of life varies from group to group, and from island to island, the total effect of Christianity has been to minimise the sanctions of the past, even if at times it has failed to exalt the spiritual authority of Christ. The historian is not necessarily concerned with the moral problem of the" rightness" of missionaries being sent to non-Christian countries. He is more concerned with the success or failure of the missionaries to do what they set out to do, and with their management of the problems arising from their contact with other peoples and other ways of life. He must, before all, record change. The change that had taken place before 1860, in eastern Polynesia, was in most cases only half a change. A new culture had been grafted on to the old, but in other instances it appeared that a reorientation had simply been given to the old ways. It is the purpose of this study to show something of the mentality of the missionaries who sought to change the social systems of the South Seas. The Evangelical missionary emerges as a special type of actor in the account of the relations between Europeans and native peoples. If, in the early years, he seems to fall into more categories, by the 1860s, by virtue of more uniform training, he had become somewhat stereotyped. In relation to the role of the Evangelical missionary two other points might be made. The first is the development of a new mentality in the national scene. We see in the heredity and environment of the mission families, the growth and culture of a similar spirit to that Evangelical zeal which took the missionaries to the field. This spirit, reinjected back into the national life, has served as a powerful stimulus to progress. Out of the mission field came men who knew their own minds. It is surprising the number of distinguished and influential, people, by no means restricted to the religious world, who derive immediately from the mission families, and who have enriched the national life. Secondly, it might be observed that the impact of the Evangelical missionaries often provided the quickest w ay to self-assertion by the native peoples. In the world of culture conflict, which is in a sense, the world of Evangelical religion, the islander was given a beam to support himself against the tide of new concepts. Wherever that beam was grasped, the islander* s potentials for self-assertion were increased.

description: In closed hydroponic systems, periodic readjustment of nutrient solution is necessary to continuously provide stable environment to plant roots because the interaction between plant and nutrient solution changes the rate of ions in it. The traditional method is to repeat supplying small amount of premade concentrated nutrient solution, measuring total electric conductivity and pH of the tank only. As it cannot control the collapse of ion rates, recent researches try to measure the concentration of individual components to provide insufficient ions only. However, those approaches use titrationlike heuristic approaches, which repeat adding small amount of components and measuring ion density a lot of times for a single control input. Both traditional and recent methods are not only time-consuming, but also cannot predict chemical reactions related with control inputs because the nutrient solution is a nonlinear complex system, including many precipitation reactions and complicated interactions. We present a continuous network model of the nutrient solution system, whose reactions are described as differential equations. The model predicts molar concentration of each chemical components and total dissolved solids with low error. This model also can calculate the amount of chemical compounds needed to produce a desired nutrient solution, by reverse calculation from dissolved ion concentrations.

description: Gaseous Bose-Einstein condensates of 2-3 million atoms were loaded into a microfabricated magnetic trap using optical tweezers. Subsequently, the condensates were released into a magnetic waveguide and propagated 12 mm. Single-mode propagation was observed along homogeneous segments of the waveguide. Inhomogeneities in the guiding potential arose from geometric deformations of the microfabricated wires and caused strong transverse excitations. Such deformations may restrict the waveguide physics that can be explored with propagating condensates.

description: We study, both numerically and analytically, the development of equilibrium after preheating. We show that the process is characterised by the appearance of Kolmogorov spectra and the evolution towards thermal equilibrium follows self-similar dynamics. Simplified kinetic theory gives values for all characteristic exponents which are close to what is observed in lattice simulations. The resulting time for thermalization is long, and temperature at thermalization is low, $T \sim 100$ eV in the simple $λΦ^4$ inflationary model. Our results allow a straightforward generalization to realistic models.

description: Aims: To determine the clinical effectiveness and safety of venous thromboembolism (VTE) prophylaxis using United States- (US) and Europe-approved anticoagulants relative to extended-duration VTE prophylaxis with betrixaban. Low molecular weight heparins (LMWHs), unfractionated heparin (UFH), fondaparinux sodium and placebo were each compared to betrixaban, as standard-duration VTE prophylaxis for hospitalized, nonsurgical patients with acute medical illness at risk of VTE. Materials and methods: A systematic literature review was conducted up to June 2019 to identify randomized controlled trials (RCTs) of VTE prophylaxis in hospitalized, nonsurgical patients with acute medical illness at risk of VTE. Studies that reported the occurrence of VTE events (including death) and, where possible, major bleeding, from treatment initiation to 20-50 days thereafter were retrieved and extracted. A Bayesian fixed effect network meta-analysis was used to estimate efficacy and safety of betrixaban compared with standard-duration VTE prophylaxis. Results: Seven RCTs were analyzed, which compared betrixaban with LMWHs, UFH, fondaparinux sodium, or placebo. There were significantly higher odds (median odds [95% credible interval]) of VTE with LMWHs (1.38 [1.12-1.70]), UFH (1.60 [1.05-2.46]) and placebo (2.37 [1.55-3.66]) compared with betrixaban. There were significantly higher odds of VTE-related death with placebo (7.76 [2.14-34.40]) compared with betrixaban. No significant differences were observed for the odds of major bleeding with all comparators, VTE-related death with any active standard-duration VTE prophylaxis, or of VTE with fondaparinux sodium, compared with betrixaban. Limitations and conclusions: In this indirect comparison, betrixaban was shown to be an effective regimen with relative benefits compared with LMWHs and UFH. This indicates that betrixaban could reduce the burden of VTE in at-risk hospitalized patients with acute medical illness who need extended prophylaxis, though without direct comparative evidence, stronger conclusions cannot be drawn.

description: Suppose one is faced with the challenge of tissue segmentation in MR images, without annotators at their center to provide labeled training data. One option is to go to another medical center for a trained classifier. Sadly, tissue classifiers do not generalize well across centers due to voxel intensity shifts caused by center-specific acquisition protocols. However, certain aspects of segmentations, such as spatial smoothness, remain relatively consistent and can be learned separately. Here we present a smoothness prior that is fit to segmentations produced at another medical center. This informative prior is presented to an unsupervised Bayesian model. The model clusters the voxel intensities, such that it produces segmentations that are similarly smooth to those of the other medical center. In addition, the unsupervised Bayesian model is extended to a semi-supervised variant, which needs no visual interpretation of clusters into tissues.

description: Introduction: Medical students have high rates of distress and burnout, exacerbated by a high academic workload. Resilience is stated to mitigate such stress, and even allow positive adaptations in the face of such challenges. Despite this, no research has examined the relationship of resilience on the academic performance of medical students. Methods: The goal of our study was to investigate the association between resilience on academic performance. We surveyed all year 2, 3, and 4 medical students (n = 160), and combined this with data on past and future course performance. We conducted an analysis of the internal consistency and validity of the RS-14, suggesting two factors: which we represent as self-assuredness and drive. We then analyzed future course performance using multiple regression. Results: Models utilizing the combined RS-14 score suggested past-performance as the only significant predictor of future course performance. Considering self-assuredness and drive as separate predictors demonstrated self-assuredness to be a predictor of improved performance in lower-than-average students, whilst drive was a predictor of improvement in higher-than-average students. Conclusions: We suggest that the conceptualization of resilience needs greater nuance, and consideration in tandem with broader psychosocial concepts, as it may exert different effects for different students.

description: Theoretical predictions are given for the strange sea distributions in the nucleon based on the flavor SU(3) chiral quark soliton model, with emphasis upon the asymmetry of quark and antiquark distributions. We find that the quark-antiquark asymmetry of the strange sea is much larger for the longitudinally polarized distribution functions than for the unpolarized ones. A preliminary comparison with the CCFR data for the unpolarized $s$-quark distribution and with the LSS fits of the longitudinally polarized distribution functions is encouraging.

description: The pursuit of nation-building dreams persists in certain regions of Africa; however, recent years have witnessed fractures within many African states, primarily stemming from conflicts. These conflicts have led to brutal battles among various African groups, resulting in devastating consequences. Examples include the longstanding conflicts among the Karamajong of Uganda and the Pokots and Marakwets in Kenya, as well as the Muslim-Christian conflict in Sudan and the genocides in Rwanda and Burundi.

This paper examines the complexities of conflict dynamics in Africa, focusing on the socio-political tensions and violent confrontations that have plagued the continent in recent years. Drawing upon historical and contemporary examples, such as the inter-ethnic clashes in Uganda and Kenya and the religious strife in Sudan, the paper explores the multifaceted roots of conflict and its profound impact on African societies.By delving into the underlying causes and consequences of these conflicts, the paper aims to contribute to a deeper understanding of the challenges facing African nations in their quest for stability and nation-building. It underscores the urgent need for effective conflict resolution mechanisms and sustainable peace-building efforts to address the underlying grievances and promote reconciliation and development in the region

description: High concentration agricultural facilities such as vertical farms or plant factories consider hydroponic techniques as optimal solutions. Although closed-system dramatically reduces water consumption and pollution issues, it has ion-ratio related problem. As the root absorbs individual ions with different rate, ion rate in a nutrient solution should be adjusted periodically. But traditional method only considers pH and electrical conductivity to adjust the nutrient solution, leading to ion imbalance and accumulation of excessive salts. To avoid those problems, some researchers have proposed ion-balancing methods which measure and control each ion concentration. However, those approaches do not overcome the innate limitations of ISEs, especially ion interference effect. An anion sensor is affected by other anions, and the error grows larger in higher concentration solution. A machine learning approach to modify ISE data distorted by ion interference effect is proposed in this paper. As measurement of TDS value is relatively robust than any other signals, we applied TDS as key parameter to build a readjustment function to remove the artifact. Once a readjustment model is established, application on ISE data can be done in real time. Readjusted data with proposed model showed about 91.6 ~ 98.3% accuracies. This method will enable the fields to apply recent methods in feasible status.

description: THE Fijian people, although they are of basically Melanesian stock, have been subjected to Polynesian influences particularly on the leadership system within their social organization, which made possible political developments in the nineteenth century that could not otherwise have occurred. Between the time of the first contact with Europeans at the end of the eighteenth century, and the conversion of the people to Christianity in the fifth decade of the nineteenth, the greater part of the group came within the control of a small number of chiefs who extended their sphere of influence, first by 'federating' with less important neighbouring chiefs, and then by conquering their more powerful rivals. The process of conquest, by which effective political power in central Fiji was consolidated under the chief of Bau, was made possible by the introduction of the musket by the first Europeans.

description: We study the production and the observability of Lambda*(1520), K*0(892), and Sigma*(1385), strange hadron resonances as function of the freeze-out conditions within the statistical model of hadron production. We obtain an estimate of how many decay products are rescattered in evolution towards thermal freeze-out following chemical freeze-out, and find that the resonance decay signal is strong enough to be detected. We show how a combined analysis of at least two resonances can be used to understand the chemical freeze-out temperature, and the time between chemical and thermal freeze-outs.

Melobasina fossicollis

description: Melobasina fossicollis (Kerremans, 1906)
 Exagistus fossicollis Kerremans, 1906: 415. Type locality: Solomon Islands: Shortland Island [Not Bismark Archipelago!]
 Melobasina fossicollis: OBENBERGER (1923): 17 (note; new combination); OBENBERGER (1930): 420 (catalogue; distribution: ‘Archipel Bismarck’ – mistake); HOŁYŃSKI (1993): 27 (note); BELLAMY (2008): 625 (catalogue; distribution: Australasian: Papua New Guinea, Bismark Archipelago – mistake).
 Remarks. KERREMANS (1906) mentioned ‘2 exemplaires, des îles Shortland’ (length 13 mm, width 4 mm); OBENBERGER (1923) transferred this species to the genus Melobasina, evidently based on the study of one of both syntypes and on illustration of M. apicalis in KERREMANS (1903). In the corresponding volume of Obenberger’s catalogue (Obenberger 1930: 420) from the library of Obenberger (deposited in NMPC), we can find his handwritten note that this species is represented in his collection (deposited in NMPC) but we failed to find any corresponding specimen in the collection. It is evident from the description that the type specimens came from the collection of H. E. R. von Bennigsen. A part of Bennigsen’s collection (including material from New Guinea and Bismark Archipelago) was deposited in DEIC (HORN et al. 1990) and the rest was left in the collection of Bennigsen in Waitze an der Warthe (now Wiejce, by Warta river, Wojewódstwo Lubuskie, western Poland) but this species is not mentioned in the list of types deposited in DEIC (GAEDIKE 1985) and we failed to find any data about the fate of the rest of Bennigsen’s collection (e.g. in GAEDIKE 1995). According to BELLAMY (2008), the type is deposited in MNHN but we did not find this type in MNHN or BMNH. It is also not mentioned in the list of types housed in IRSN. Given the original description and the type locality, we accept the transfer proposed by OBENBERGER (1923). We are also inclined to believe that M. fossicollis and M. apicalis are conspecific.
 Distribution. Solomon Islands (Shortland Island).

description: Background: The World Health Organization recommends use of a single yellow fever (YF) vaccine dose for life and fractional doses in outbreaks when there are limited vaccine stocks. In endemic regions, this vaccine is given as part of routine infant immunization programs around 9 months of age. There is a need to better understand immune responses when vaccinating infants particularly in contexts where the child may be malnourished. Methods: Data from 393 Malian and Ghanaian infants who concomitantly received measles and YF vaccines at 9 to 11 months of age were retrospectively analyzed. Response to YF vaccine was examined for association with nutritional status at time of vaccination, sex, age, pre-vaccination titers and season of vaccination. Results: Neutralizing antibodies following vaccination were unaffected by season of vaccination, sex, pre-vaccination titers or nutritional status, though there was a trend to higher titers in males and children with higher height for age z-scores. Seroconversion rates differed significantly between countries (63.5 in Ghana vs. 91.0% in Mali). Conclusion: Longitudinal, prospective studies are needed to optimize the use of YF vaccine in infants in endemic settings. There may be a need for booster vaccinations and to compare various vaccine preparations to optimize the use of available vaccines.
Weak Separation, Positivity and Extremal Yangian Invariants

description: We classify all positive n-particle N^kMHV Yangian invariants in N=4 Yang-Mills theory with n=5k, which we call extremal because none exist for n>5k. We show that this problem is equivalent to that of enumerating plane cactus graphs with k pentagons. We use the known solution of that problem to provide an exact expression for the number of cyclic classes of such invariants for any k, and a simple rule for writing them down explicitly. As a byproduct, we provide an alternative (but equivalent) classification by showing that a product of k five-brackets with disjoint sets of indices is a positive Yangian invariant if and only if the sets are all weakly separated.

description: We integrate the third and a half post-Newtonian equations of motion for a fully generic binary black hole system, allowing both for non-circular orbits, and for one or both of the black holes to spin, in any orientation. Using the second post-Newtonian order expression beyond the leading order quadrupole formula, we study the gravitational waveforms produced from such systems. Our results are validated by comparing to Taylor T4 in the aligned-spin circular cases, and the additional effects and modulations introduced by the eccentricity and the spins are analyzed. We use the framework to evaluate the evolution of eccentricity, and trace its contributions to source terms corresponding to the different definitions. Finally, we discuss how this direct integration equations-of-motion code may be relevant to existing and upcoming gravitational wave detectors, showing fully generic, precessing, eccentric gravitational waveforms from a fiducial binary system with the orbital plane and spin precession, and the eccentricity reduction.
Electron teleportation with quantum dot arrays

description: An electron teleportation protocol, inspired by the scenario by Bennett et al., is proposed in a mesoscopic set-up. A superconducting circuit allows to both inject and measure entangled singlet electron pairs in an array of three normal quantum dots. The selection of the teleportation process is achieved in the steady state with the help of two superconducting dots and appropriate gating. Teleportation of the electron spin is detected by measuring the spin-polarized current through the normal dot array. This current is perfectly correlated to the pair current flowing inside the superconducting circuit. The classical channel required by Bennett's protocol, which signals the completion of a teleportation cycle, is identified with the detection of an electron charge in the superconducting circuit.

Dr. Bland in New South Wales

Subjects: subject: Bland, W. 1789-1868(William),

description: William Bland, ex-Royal Navy surgeon, convicted and transported for killing a fellow—officer in a duel, left the Frederick and stepped ashore in Sydney, in July, 1814, into a new world* Born and nurtured in a comfortable middle-class family, trained as a surgeon, he suddenly found himself cut off from the protected and regulated life of a service officer and thrust, on the wrong side of the social ledger, into a convict society on the other side of the world. Macquarie's world was not a pleasant place. Society was stratified by rigid class divisions. Crime and drunkenness were very common* Both men and women habitually gave themselves over to low sensual gratification. The government was autocratic and government officials omnipotent. Personal, political and economic freedoms were restricted in the interests of a benevolent but patronising encouragement of criminal reform. Into this environment came a proud, irascible and sensitive man, smarting from a sense of injustice, incurred from his involvement in a crime, which, in his view, was no more than an unfortunate end to the settlement of a matter of honour. The gaol—like colony, still clinging precariously to the coastal fringe surrounding Port Jackson, formed an uninspiring background to a half-century of distinguished public service. Yet Bland remained in the colony after his pardon was granted, and achieved a unique position in the society and land of his adoption.

Quichuana ursula

description: QUICHUANA URSULA HULL, 1949: 136
The holotype is a male collected on 4.xii.1947 at Pucallpa, Peru, by Jose Schunke. According to Hull (1949) this specimen was in his collection, but is apparently missing from CNC (J. Skevington, pers. comm.).
 Range
Peru.
 Taxonomic notes (based on the description in Hull, 1949)
 Quichuana ursula is similar to Q. picadoi, but they can be readily separated by the colour of the pro- and metatibia, which are dark brown in the former and yellow, at least on the basal half, in the latter species. The face is extensively pollinose except for a central stripe, but it also has two indistinct lateral stripes. Although Hull (1949) hypothesized that this could be the male of Q. nigricans, this is unlikely because of the difference in body size (Q. nigricans, 12 mm, and Q. ursula, 8 mm) and because of other differences, such as the proportional length of the basoflagellomere, both of which were characters highlighted by Hull (1949).
