Time is a complex concept. As such, its understanding and manipulation on a cognitive level develops slowly during childhood and adolescence. The present study examines problem-solving, reasoning and metacognitive abilities of schoolaged children on temporal-relation problems. It also examines the influence of different representationalmeans of time quantification, i.e., numerical and figural, on children’s performance. This research concerns 233 school-aged children, which were presented with seven problems. They were first asked to answer each problem. After solving the problem, half of the children were asked to represent the described temporal relations in numbers and then in figures, whereas the other half had to represent the problem in the opposite order. After each representation, children were asked to check their original answer to the problem, with the option to either maintain it or revise it. Results show that for school-aged children: (a) “initial temporal order” is a difficult concept to grasp compared to the concepts of “final order” and “duration of events”; b) the use of numbers leads to adequate representation of time and facilitates the figural one, whereas the opposite pattern was not observed; and c) up to 10 years of age, children’s meta-cognitive, and especially selfcorrection capacity, seems to be very poor.

Multiple word associations to 65 words, 52 of which were CVCs, were obtained from 100 boys and 100 girls in Grades 4, 6, and 8, aged respectively, 9 and 10, 11 and 12, 13 and 14. Conventional word-association norms were developed for each of these grade-sex groups for first, second, and third responses, separately and pooled. Meaningfulness values for each word, defined as the mean number of associations, were also determined for each group. Analysis of the primaries disclosed that approximately half the set of words had primaries which were the same across all groups and that such primaries were on the average of much higher frequencies than primaries which differed among groups. Primaries which differed among groups very often occurred as secondaries or tertiaries of the other groups. Frequency of primaries did not vary between sexes or across grade-age levels. While m values for the set of words increased with grade and age, the rank ordering of these values was essentially the same within each grade-age-sex group. Sex was not related to m values. Values of m when compared with Noble's m′ showed significant agreement both for rank-order comparisons and values dichotomized into high and low categories.

Recent findings indicate that the presence of formant transitions aids the perception of the order of stimuli in repeating sequences of vowels or consonant-vowel (CV) syllables. In this study, 12 listeners reported the perceived order of four vowels or CVs in repeating sequences. Stimuli ranged in duration from 75 to 300 msec in 25-msec steps. Four stimulus sequences were used (1) varying vowels (Vv), (2) CVs with varying consonants but a constant vowel (CvVc), (3) CVs with a constant consonant but varying vowels (CcVv), (4) CVs with consonants and vowels varying (CvVv). Percentage of correct identification of order was significantly higher and mean threshold duration significantly lower for the CvVv and CvVc conditions than for the Vv condition. Mean number of sequences per response was significantly smaller for the CvVv condition than for the other conditions. Threshold durations ranged from 100 msec for the CvVv sequences to 135 msec for the Vv sequences. Ordering performance was nearly perfect for stimulus durations of about 225 to 250 msec. The results support the hypothesis that as stimuli in repeating sequences more closely resemble connected speech, listeners can more easily correctly identify the order of the stimuli.

<p>This paper aims at reviewing the supportive and therapeutic contribution of ICTs on the most common psychoemotional disorders of childhood and adolescence. The various approaches to classifying behavioral and emotional dysregulations in children and adolescents have been reviewed and the boundaries between normative variation and clinically significant presentations have been determined. Furthermore, we present the major categories of mental illnesses in children and adolescents investigating the etiology, the diagnostic criteria, the epidemiology and treatments by critically reviewing the outcomes of relevant studies. The findings indicate that significant steps have been made in this field, but it is vital to underline the need for more extended investigation in school aged children and adolescents for this purpose.</p>

We developed a real-time copy number polymerase chain reaction assay for deletions on chromosome 20q (del20q), screened peripheral blood granulocytes from 664 patients with myeloproliferative disorders, and identified 19 patients with del20q (2.9%), of which 14 (74%) were also positive for JAK2-V617F. To examine the temporal relationship between the occurrence of del20q and JAK2-V617F, we performed colony assays in methylcellulose, picked individual burst-forming units–erythroid (BFU-E) and colony-forming units–granulocyte (CFU-G) colonies, and genotyped each colony individually for del20q and JAK2-V617F. In 2 of 9 patients, we found that some colonies with del20q carried only wild-type JAK2, whereas other del20q colonies were JAK2-V617F positive, indicating that del20q occurred before the acquisition of JAK2-V617F. However, in colonies from 3 of 9 patients, we observed the opposite order of events. The lack of a strict temporal order of occurrence makes it doubtful that del20q represents a predisposing event for JAK2-V617F. In 2 patients with JAK2-V617F and 1 patient with MPL-W515L, microsatellite analysis revealed that del20q affected chromosomes of different parental origin and/or 9pLOH occurred at least twice. The fact that rare somatic events, such as del20q or 9pLOH, occurred more than once in subclones from the same patients suggests that the myeloproliferative disorder clone carries a predisposition to acquiring such genetic alterations.

Abstract When interpreters orient Kant’s philosophy of time in relation to McTaggart’s distinction among different ways of characterizing a temporal order, they claim that he is best described as endorsing an A series position according to which there is a metaphysically privileged present that determines the past and the future. Whether Kant might also be understood as a proponent of the B series - according to which there is no privileged present, but rather time is comprised of relations of earlier than, later than, and simultaneity - has not been discussed in the literature. I argue that, for Kant, the appearances can be described as an A series, while the phenomena are to be understood as a B series, neither of which is more fundamental than the other. Contra a common approach in the literature that neglects a metaphysical difference between appearances and phenomena, I argue Kant’s transcendental idealism about time is best understood in relation to his account of appearances and phenomena.

In the theory of the specific heats of gases of diatomic molecules the functionplays a well-known and important part. The rotational specific heat Crot of a diatomic molecule, which is susceptible of representation as a rigid body with two equal principal moments of inertia, without spin about the other principal axis, is given bywhere R is the gram-molecular gas-constant andthe pair of equal moments of inertia being equal to A. Whether such a model is or is not an adequate representation is a matter for determination by a detailed study of the structure of the band spectrum, particularly of the nature of the normal electronic and vibrational state. It is known to be applicable to normal molecules of the halogen hydrides, to CO and other molecules which have a normal state of type 1S including (but for a certain special feature) H2.

Two retrospective tests are described for the assessment of remote memory for past events. Both tests ask about former television programs broadcast for a single season from 1957 to 1972. One test asks about the plots of programs, and the other asks for judgments about their temporal order. The usefulness of such tests for experimental and clinical studies of memory is discussed.

AbstractHaving identified the differences between the concept of legality and the much more complex concept of legitimacy, the author scrutinizes the legality and the legitimacy of the existing international criminal tribunals. Their legality has been put in doubt only concerning the International Criminal Tribunal for the former Yugoslavia (ICTY) and the Special Tribunal for Lebanon (STL), but the criticisms have been or could be overcome. Assessing the legitimacy of these tribunals is instead a more difficult task. In fact, misgivings have been voiced essentially concerning the legitimacy of the ICTY and the STL, but not the International Criminal Court (ICC) and the other international criminal courts. The legitimacy of the STL in particular deserves to be discussed: even assuming that the STL initially lacked some forms of legitimacy, it could achieve it – or confirm it – through its ‘performance legitimacy’. The author then suggests what the realistic prospects for international criminal justice are. Convinced as he is that it is destined to flourish even more, he tries to identify the paths it is likely to take in future years.

Este artigo tem como principal objetivo discutir e avaliar a importância das habilidades sociais em crianças com idade escolar. O termo habilidades sociais refere-se à existência de diferentes classes de comportamentos sociais no repertório do indivíduo para lidar de maneira assertiva com as demandas das situações interpessoais. Foi realizada uma revisão bibliográfica em seis estudos publicados por pesquisadores da área, entre os anos de 2002 a 2016. Os resultados evidenciaram que habilidades sociais são reconhecidas como fator de proteção no curso do desenvolvimento humano. Tais habilidades são atenuadas em contexto escolar pois dizem respeito a comportamentos necessários a uma relação interpessoal bem-sucedida, conforme parâmetros típicos de cada contexto e cultura, podendo incluir os comportamentos de iniciar, manter e finalizar conversas; pedir ajuda; fazer e responder a perguntas; fazer e recusar pedidos; defender-se; expressar sentimentos, agrado e desagrado; pedir mudança no comportamento do outro; lidar com críticas e elogios; admitir erro e pedir desculpas e escutar empaticamente, dentre outros. Para isso foi realizado um levantamento nas seguintes bases de dados: BVS PSI, Pepsic, Google Acadêmico e Scielo, Portal de periódicos CAPES/MEC considerando o que tem sido produzido a respeito deste tema nos últimos anos no Brasil. STUDIES ON SOCIAL SKILLS IN SCHOOL-AGED CHILDREN ABSTRACT This article aims to discuss and evaluate the importance of social skills in school-aged children. The term social skills refers to the existence of different classes of social behaviors in the repertoire of the individual to deal assertively with the demands of interpersonal situations. A bibliographic review was carried out in six studies published by researchers from the area between 2002 and 2016. The results showed that social skills are recognized as a protection factor in the course of human development. Such skills are attenuated in the school context because they relate to the behaviors necessary for a successful interpersonal relationship, according to typical parameters of each context and culture, which may include the behaviors of starting, maintaining and ending conversations ask for help; ask and answer questions; make and refuse orders; defend yourself; expressing feelings, liking and displeasure; ask for change in the behavior of the other; dealing with criticism and praise; admit mistakes and apologize and listen empathically, among others. For that, a survey was carried out in the following databases: BVS PSI, Pepsic, Google Scholar and Scielo, periodicals portal of CAPES/MEC journals, considering what has been produced about this topic in recent years in Brazil.

The article reflects the main periods of the life of the Ukrainian scientist, engineer, professor of architecture Sergiy Tymoshenko, namely his public, political, educational and scientific activity since his childhood and adolescence, study at the Institute of Civil Engineers in St. Petersburg. His activity as an architect in Volyn, Kyiv and Kharkiv, the construction projects he has created in these regions, are analysed. He tried to recreate the Ukrainian national style of construction — the Cossack Baroque. As a supporter of Ukrainian independence, he took an active part in the development of its statehood and during 1919–1920 he worked as the Minister of Roads in the governments of the UNR. After the defeat of the national liberation struggle Tymoshenko became an emigrant, where he was engaged in the development and implementation of construction projects, later he worked as a teacher in the Ukrainian Academy of Economics and the Ukrainian Studio of Plastic Arts (Academy). Together with the other representatives of the intelligentsia, he led a public activity, defending Ukrainian spiritual values. After moving to the USA, Sergiy Tymoshenko worked as an architect.
