Aëdes argenteus, Poiret, is a very variable mosquito, and it was thought that it would be interesting to examine a number of freshly-hatched and therefore undamaged specimens and to note how many conformed to the original description. No difficulty was experienced in obtaining the necessary material, as collections of larvae are received daily from the Medical Officer of Health. One thousand of each sex of the species were mounted in the order of their emergence from the pupal case and were examined under the binocular microscope. The one constant feature was found to be the lyre-shaped marking on the thorax, although even here the outline and the centre lines varied in breadth and in colour, and the centre lines varied in length. But as the abdomen and the hind tarsus showed the greatest variations, the present paper is restricted to a description of these.

It has occured to me to say a few words upon the subject of author's types. It sometimes happens that a specimen is labelled “type,” which is not the true type, i. e., the one (or ones) from which the original description was drawn up and which accords with that description. This is the criterion for types, that they do not contradict the original description. The late Mr. Morrison sent me at one time a “type” of Harris's Agrotis tessellata. Upon my wonder at his having such a specimen, I found it was merely a compared example, but it shold not have been labelled “type”.

This book has shown how a culture of insubordination, an ideological pattern of rebellion and resistance, developed as a constant feature of Japanese military life from the Meiji Restoration onward. Tracing its roots in the shishi culture of the late Tokugawa period, military insubordination persisted into the 1870s and reached new heights during the Satsuma Rebellion of 1877. It broke into two independent components: elite resistance to state policy and the shishi tradition of the mixed gangs. The book concludes with a discussion of three “bugs” that allowed the Imperial Japanese Army's rebellious culture to grow, prosper, and radicalize with the passing years: the first bug was the hazy political legitimacy of the Meiji regime; the second was the one-way nature of territorial expansion; and the third was the endless nature of territorial expansion.

Broad divisions of preventive and curative medicine can arbitrarily exist, but there should be a wide overlap and increasing effort should be made to bring all our medical forces together in a comprehensive attack upon any factors contrary to mental and physical welfare and health in infancy and childhood. Officers in the maternity and child welfare, and school medical services, will neces sarily need to have a closer and increasing liaison with other forms of preventive and clinical practice. The identity of these officers can be retained (and must be so for some years), but the overall value in the national health service will depend on a wider fusion with consultants, especially obstetricians and pædiatricians, on the one hand, and on the other (especially in health centres) with general practitioners, and particu larly with those comprising the personnel of group general practice. Most especially in the field of child health, preventive and curative activity can proceed hand-in-hand and in fact must do so to maintain fruitful results. Pædiatricians, infant welfare officers, and school medical officers have wide overlaps in their interests and duties ; to some extent a mutual interchange of work in children's hospitals and in welfare departments already exists in several large centres. Clinical area pædia tricians should organize, with the local preventive medicine authorities, arrangements for a comprehensive child health programme in the area and so act as joint influences in promoting the very best co-operative work, and particularly in its educational preventive aspects.

SYNOPSISAn epidemic of falling, confined to one single class of a large comprehensive school in a London suburb, is described. There were 24 adolescent girls in the class, all in the 16 to 17 age group, and the class was involved in examinations. The school authorities decided to close down the class one week before the end of term, when eight girls and a young locum teacher lay unconscious on the floor. Most of the girls affected belonged to the ‘in group’: the very bright, the Greek, the Jewish, and the one coloured girl were unaffected. Although the school refused permission for a sociometric investigation, information was obtained from the school medical officer, from two teachers, and from the two girls who were clearly the most powerful members of the class and the protagonists of the epidemic. They were both referred for medical treatment and, after all physical investigations had proved negative, they were both admitted to a psychiatric hospital for observation and treatment. Their case histories are given in some detail, together with a ‘confession’ written by the girl who started the epidemic. This same girl, during the course of her hospital admission, started a ‘pseudo-pregnancy epidemic’ in her ward. It was discovered that one member of the class had left the school during the course of the previous trimester because she had become pregnant. The epidemic, which appears to follow her childbirth and subsequent death from cerebral haemorrhage, lasted from December to the following July. Possible dynamic factors are discussed.

It is rarely that we have read a more detestable book than the one under review. As its title indicates, it is a description of a lunatic, but from the beginning to the end it revolts one. To begin with, the unfortunate man, named Labat, has an insane mother, whose mother also was insane. He was wealthy and of good family, and is thus able to marry a beautiful but poor girl, who has two children, both of whom die in convulsions. A most truthful but horrible description of a fit is given, exact in all its fearful details. The mother determines to have no more children by her husband, and as the latter insists upon conjugal rights, she goes to the doctor, who is readily seduced by her, and a liaison is started, which results in the birth of a fine healthy son, who bears strong indications of his paternity. The putative father is jealous, and though he takes no open steps, he evinces his disgust, and the doctor, to save himself, calls in a medical friend, who is persuaded that the accusations against his medical ally are untrue, and who treats them as delusions, and on an urgency order consigns M. Labat to a “Maison de Sauté,” kept by an ex-marine medical officer, whose treatment is of the most downright and brutal kind; he has a belief in subduing disease by means of douches and strict discipline, the patient passes through a period of distress, and very nearly loses his reason, and the details of the life in the asylum are revolting and disgusting in the extreme. He determines to suppress his real feelings and to acquiesce in the doctor's ideas, and as a result he is discharged cured. He rejoins his wife, who, receiving him coldly, causes further trouble, which ends in the murder of the child, and the flight of M. Labat. He is taken to another asylum, which is a private adventure asylum, where more brutality is exercised, and the patients are treated more as slaves than as sufferers from disease. Thence M. Labat, who has now become really insane, is taken as an insane criminal to Bicêtre, only to be tested and tortured with electricity. He once more is sent to the original “Maison de Santé,” where in the end he is boiled to death in a hot bath by accident. Madame Labat has also become permanently insane, and so the story ends. Such a book is not only unhealthy, but it is mischievous in the last degree; it represents, as if occurring at the present day, a state of mismanagement in asylums which has disappeared for many years. It causes prejudice, not only against the medical profession as a whole, but more particularly against the special branch which we cultivate. It is an untruthful libel. The medical discussions on the symptoms of mental disorder are very exact, pointing to the handiwork of one who has had medical training. “It is a filthy bird that fouls its own nest.”

Physiological systems are best characterized as complex dynamical processes that are continuously subjected to and updated by nonlinear feedforward and feedback inputs. System outputs usually exhibit wide varieties of behaviors due to dynamical interactions between system components, external noise perturbations, and physiological state changes. Complicated interactions occur at a variety of hierarchial levels and involve a number of interacting variables, many of which are unavailable for experimental measurement. In this paper we illustrate how recurrence plots can take single physiological measurements, project them into multidimensional space by embedding procedures, and identify time correlations (recurrences) that are not apparent in the one-dimensional time series. We extend the original description of recurrence plots by computing an array of specific recurrence variables that quantify the deterministic structure and complexity of the plot. We then demonstrate how physiological states can be assessed by making repeated recurrence plot calculations within a window sliding down any physiological dynamic. Unlike other predominant time series techniques, recurrence plot analyses are not limited by data stationarity and size constraints. Pertinent physiological examples from respiratory and skeletal motor systems illustrate the utility of recurrence plots in the diagnosis of nonlinear systems. The methodology is fully applicable to any rhythmical system, whether it be mechanical, electrical, neural, hormonal, chemical, or even spacial.

Background. Brachycephalus includes miniaturized frogs with restricted geographical distributions throughout the Brazilian Atlantic Forest. Ecological data for most species are still scarce. For instance, advertisement calls have only been described for 12 of the 36 known species, including B. tridactylus, a recently described species from southern Brazil. Posteriorly, features of the advertisement call of B. tridactylus were compared with congeners and the unique characteristics of its call were highlighted. To confirm these potentially divergent characteristics, we reanalysed an original recording of B. tridactylus and analysed our own recordings and verified that the original description of its advertisement call is inaccurate. Thus, we redescribe its advertisement calls. Methods. We asked the descriptors of B. tridactylus the original recordings that they made and requested access to the only original recording deposited in a collection of sounds. We received from André Lima a copy of one recording, the same as the one that had deposited, and obtained permission to re-analyze it. We studied this recording and compared it with our own recordings, made at the type locality of the species on March, 2016. Sound samples were analysed with Raven Pro 1.5.0 and call analyses were made under a note-centered approach. Results. The original recording was amplified somehow by at least 6 dB and was also clearly low-pass filtered with a cutoff frequency of 10 kHz. Our analyses did not allow us to recognize several of the acoustic parameters normally described in Brachycephalus. The sound we heard from the notes overlapped with other signals (noise?), which prevented us from clearly determining the end of the note and other important features, such as the presence of pulses. According to our recordings (n = 15 individuals), B. tridactylus emitted a relatively long advertisement call (50.8 s, on average), composed by 10–13 notes emitted in a note rate of 3.7–8.3 notes per minute. Only isolated notes were present. The notes were composed by 1–3 pulses and the note duration varied from 0.002–0.021 s. Discussion. The original description of the call of B. tridactylus is incorrect because it included background noise and amplification artefacts as part of the call parameters. However, we recognize that the original recording and our recordings have captured the same type of call. In our measurements of the species calls, note duration was nearly an order of magnitude shorter as the original description. The existence of notes with 1–3 pulses was not acknowledged in the original description. With few pulses per notes, the advertisement call of B. tridactylus is distinct from the notes with several pulses of B. ephippium, B. pitanga, B. crispus, B. sulfuratus, and B. darkside. The advertisement calls of B. tridactylus is also distinct from that of B. albolineatus and B. mirissimus by having only isolates notes, instead of isolated notes and note groups.

Respons terhadap COVID-19 dilakukan secara berbeda oleh negara di dunia, namun satu yang pasti adalah bahwa penanganan terhadap isu ini bergantung pada kebijakan yang dikeluarkan oleh negara. Hal ini dikarenakan COVID-19 tidak hanya merupakan permasalahan kesehatan tetapi juga permasalahan kebijakan. Dalam konteks ini, salah satu negara yang menjadi sorotan adalah Amerika Serikat. Sebagai negara yang memiliki berbagai keunggulan baik material maupun imaterial, Amerika Serikat tidak berhasil merespons COVID-19 dengan kebijakan yang tepat. Tulisan ini berangkat dari premis tersebut, bahwa parahnya pandemi COVID-19 di Amerika terjadi karena adanya kegagalan pemerintahan Trump untuk memformulasikan kebijakan respons yang tepat. Dalam menguraikan argumentasi tersebut, Tulisan ini terbagi dalam  tiga bagian, bagian pertama berisi kondisi umum COVID-19 di Amerika, bagian kedua berisi tentang analisis kegagalan pemerintahan Trump, dan bagian terakhir berisi simpulan serta pelajaran yang bisa kita ambil dari kegagalan penanganan COVID-19 di Amerika.Kata-kata Kunci: COVID-19, Amerika Serikat, Trump, Kegagalan, Ketidaktahuan yang disengaja Throughout the world, countries use different strategies to curb the COVID-19 spread. The one constant feature is that it is as much a policy problem as it is a medical one. The policy becomes increasingly important due to the infectious nature of the virus. Should a country failed to employ a working strategy, human lives are at stake. In this context, the United States became increasingly important to show that policy is essential to curb the virus. The United States had a vast array of resources ranging from medical experts to a well-prepared institution. Despite all that, the US is currently the worst country in the world in terms of the number of cases and death. This paper argues that this condition is the result of the Trump administration's failure to formulate a suitable and working strategy to curb the virus. The author will explore the argument in three sections. The first section gives a glimpse of COVID-19 in the US, the second section describes the US response to the virus, the third section explains the Trump administration failure, and the last part consists of the conclusion and lesson that we can learn from US failure.Keywords: COVID-19, United States, Trump, Failure, Willful Ignorance

Between 2012 and 2016, while the financial crisis was unfolding its effects in Italy and globally, several divestments of Italian State-owned companies were carried out, leading observers to believe that a new season of privatizations — similar to the one carried out in the 1990s — had finally been launched. However, after the initial considerable divestments announcing the completion of privatization of large public companies, the momentum faded away due to the strong Italian political instability combined with an international trend oriented to nationalism. The sizeable privatizations launched in 2014-2016, which led to important results in terms of revenue and attraction of investments (including international ones), produced lights and shadows, mainly due to the lack of a long-term roadmap. In this context, the only constant feature of any privatization strategy in Italy appears to be the feeble and fluctuating trend that — today just like yesterday — prevents the country from fully exploiting the potential implicit in the divestment of large State-owned companies.

Two new and three known species of the genera Aponema Jensen, 1978, Molgolaimus Ditlevsen, 1921, Sabatieria Rouville, 1903, and Terschellingia De Mann, 1888 were found at the deep-sea Håkon Mosby Mud Volcano, at a depth of 1250m, in the Norwegian Sea. Aponema ninae sp. n. is characterized by short body length, short spicules, gubernaculum with wide apophyses, which are bevelled on the top, and long narrowed tail with drop-shape thickened tip and caudal setae. The new species most resembles Aponema torosa (Lorenzen, 1973). Molgolaimus haakonmosbiensis sp. n. differs from all other species of Molgolaimus by shape and length of spicules; relations of spicule length to the anal body diameter; presence of two supplements. Spicules of the new species are short (30.5 µm), slender, twisted with amplate and excurved proximal parts. The appearance of our specimen of Sabatieria ornata fits well with the original description of Ditlevsen, 1918. Specimens of Terschellingia distlamphida Juario, 1974 also fit the original description based on nematodes sampled from the sub littoral of the German Bight. However, the Norwegian specimens have a shorter (1010 µ m vs. 1343 µ m) and thicker body (a=64.6 µ m vs. a=32.0 µm). The Håkon Mosby specimens of Terschellingia longicaudata De Mann, 1907 differ from the original description in body length and thickness: 1094 µm vs. 1429 µm, and a=22.3 µm vs. 49.0 µm correspondingly, but agree with descriptions by other authors, especially with the one by Chitwood (1951).
