Southwestern Alaska

Despite considerable activity during the last two decades our knowledge of the archaeology of Alaska is still rather scanty. Very few places have been thoroughly investigated, and almost all work has been confined to two areas, a northern including St. Lawrence Island and a southern including the Aleutian Islands. The intermediate area, from Wales to Port Möller, with a coast line of approximately 2000 miles, is virtually unknown from an archaeological point of view. If archaeological material from this area exists in museum collections, it is unpublished and thus useless to most students.The need of information about the archaeology of this part of Alaska was felt very badly by the writer during his work on the analysis of the Ipiutak culture. When it became apparent that early Kachemak Bay culture must belong to the same Paleo-Eskimo complex as Ipiutak, it was natural to assume the former existence of the same complex in the intermediate area, an assumption which ethnological evidence seems to bear out.

This paper aims to bring into the ethical debate on covert research two aspects that are neglected to date: the perspective of the research subjects and the special responsibility of investigators towards their observers. Both aspects are falling behind, especially in quantitative social research. From a methodological point of view, quantitative forms of covert observation involve a great distance between the researcher and the research subjects. When human observers are involved, the focus is usually on the reliable application of the measuring instrument. Therefore, herein, a quantitative study is used as an example to show how the protection needs of both the observed persons and the observers can be met in practice. The study involved 40 student observers who covertly captured everyday conversations in real-world settings (e.g. in cafés or trains) by a highly standardised observation scheme. The study suggests that the anonymity of the research subjects and their trust in the observers are crucial for their subsequent consent. However, many participants showed only little or even no interest in the written information they were provided. Further, this study strongly emphasises how mentally stressful covert observations are to the observers. Almost all observers were worried in advance that the people they were observing would prematurely blow their cover and confront them. Role-playing and in-depth discussions in teams are good strategies to alleviate such and other fears and to prepare student assistants well for their demanding work in the field.

The German version of Riemann’s Collected Works is confined to a single volume of 690 pages. Even so, this volume has had an abiding and profound impact on modern mathematics and physics, as we shall see. In fifteen years of activity, from 1851, when he gained his doctorate at the University of Göttingen, to his death in 1866, two months short of his fortieth birthday, Riemann contributed to almost all areas of mathematics. He perceived mathematics from the analytic point of view and used analysis to illuminate subjects as diverse as number theory and geometry. Although regarded principally as a mathematician Riemann had an abiding interest in physics and researched significantly in the methods of mathematical physics, particularly in the area of partial differential equations.

Sympatric Morphs

Three sympatric morphs of Pseudomallada prasinus (Burmeister, 1839) were hybridized in search of reproductively     separated species. In addition, 26 morphological and biological traits were recorded for living and preserved specimens of the three morphotypes.                                                                                                         Cross-breeding experiments showed that the prasinoid morph “marianus” is a different species from either the “greenhead” or “sulfurhead” morphs. All three are morphologically and biologically distinct. “Greenhead” and “sulfurhead” are small to medium sized and deposit eggs singly, without obligatory diapause in the second instar. In most specimens of these two smaller “prasinus” morphs there is a red or brown suture below the antennae, which can fade with age or preservation. P. “marianus” is a large species, depositing bundled eggs, with an obligatory diapause in about half of the L2. In none of the collected or reared P. “marianus” was a red or brown suture below the eyes observed. The forewing sizes of the type specimens of Chrysopa prasina Burmeister, 1839, C. coerulea Brauer, 1851, and C. marianus Navás, 1915 differ significantly from those of C. aspersa Wesmael, 1841 and other, later synonymized type specimens such as C. sachalinensis Matsumura, 1911, C. burri Navás, 1914, C. caucasica Navás, 1914, or C. vernalis Navás, 1926. This strongly suggests that the “marianus” morph is the real P. prasinus and the “greenhead” and “sulfurhead” morphs correspond to P. aspersus or one of the later synonymized species with smaller wing size.Pseudomallada marianus (Navás, 1905) is confirmed as a synonym of P. prasinus, depositing bundled eggs, whereas smaller prasinoid morphs, depositing single eggs, are not P. prasinus—and are morphologically distinct from P. abdominalis (Brauer, 1856). Pseudomallada aspersus (Wesmael, 1841) is a valid species, but at this point it is not possible to assign it to one of the prasinoid morphs because most of the live color traits are not discernible in old type specimens. A diagnostic description of the “real” P. prasinus can separate almost all P. prasinus specimens, even in museum collections, from P. aspersus (likely to be the “greenhead” morph) and the Mediterranean “sulfurhead”.

The aim of the study was to analyse the content of museum labels from various periods in terms of their usefulness in creating new labels for exhibits included in museum collections. Nearly 5,000 museum labels from the years 1811 to 2017 were reviewed, for exhibits at the Museum of Zoology of the Polish Academy of Sciences in Warsaw, Herbarium of the University of Wroclaw, and the Museum of Forensic Medicine at the Medical University of Wroclaw. On the basis of the collected information, an attempt was made to develop a ‘universal label’template, including a range of necessary information from the point of view of managing and maintaining the accessibility of the relevant collection.

The article suggests returning to the “crowd” as an object of sociological analysis. Crowds have attracted early sociologists because crowds were visual embodiments of social forces that surpass individuals and also served as a symbol of the profound social transformations which were taking place in the late 19th and early 20th centuries. Analyzing crowds allowed for the first sociologists (G. Simmel, R. Park, M. Weber, E. Durkheim) to oppose the psychological interpretation of mass social phenomena with a purely sociological approach. However, in the second half of the 20th century sociologists had lost almost all interest in the crowd, as it did not meet the interests of researchers of “large” social structures, nor the interests of the proponents of interactionist approaches. This article shows that the crowd can again be made interesting for sociology if we were to consider it from the point of view of the everyday practices of the participants. In these everyday practices a specific form of phronesis, i.e. practical wisdom, technical skill coupled with moral judgment about which action is good and which is not, is implemented. It is shown here that the study of the practical wisdom of walking in a crowd requires special concepts and methods that can be found in phenomenology and ethnomethodology. The article suggests using three such concepts for the analysis of crowds: phenomenal field, oriented object, and figuration of details. With the help of these concepts, the methods of the crowd’s situated social order production are analyzed in relation to the management of speed and trajectories of movement, following one another, walkers’ stopping and slowing down, and joining the crowd. This analysis shows that the joint production of the crowd’s social order by its participants is a situated practice, i.e. it consists of making the local scenes of everyday life familiar and accountable, and of assessing the local adequacy of the actions performed.

Technological development has changed human life style. Child's world that was once filled with traditional games has now been eroded by technological advances. Nowadays online games that replace traditional games are not only favored by children, almost all levels of human age like playing online games. But behind it all there is a negative impact that haunts its users. This study aims to reveal the negative side of using online games from the point of view of Islam and Islamic Psychology. The technique used is literature review by compiling some previous articles. The results showed that excessive use of online games will give a bad impact on the physical and psychological users, such as visual impairment, sleep disturbance, addiction, violence and stress. The use of online games is also considered more disadvantage than the benefits and it’s seen as an activity that wastes time, and it is prohibited in Islam.

Background. The article provides an overview of existing complexes (units) for continuous monitoring of drilling fluid parameters in automatic mode. Aim. To justify the need to develop a complex (module) that will allow combining existing technologies and making a step forward in the field of process automation in terms of monitoring the parameters of drilling fluids. Materials and methods. In the current realities of well construction, the control of drilling fluid parameters on almost all drilling rigs operating on the territory of Russia (possibly with the exception of a few off shore projects) is carried out by the work of a solution engineer, usually a representative of a service company. The analysis of the parameters, depending on the number of personnel, the speed of penetration, the complexity or importance of the well, can be carried out from 2 to 6 times a day [1, 2]. This means a complete analysis, rather than monitoring the density and conditional viscosity, which can be measured by a representative of the drilling crew, for rapid response, and with greater frequency. Due to such a low measurement discreteness, there is a high probability of a significant deviation of the drilling fluid parameters from the design values. As a result, the probability of various complications, both geological and technological, increase significantly. Results. During the analysis of information from open sources, the most promising complexes (modules) from the point of view of application in the current conditions were identified, their positive and negative sides were evaluated. As a result of the conducted review of open sources, the most promising complexes (modules) in terms of application in the current conditions are identified, the positive and negative sides of the systems under consideration are displayed, and the need to develop a complex (module) that will combine all the best that is available today and make a qualitative step forward in the field of “peopleless” technologies used during drilling wells in terms of monitoring the parameters of drilling fluids is justified. Conclusions. The necessity of developing a complex (module) for automating processes in terms of monitoring the parameters of drilling fluids is justified.

Objetives: The main aim of our work is to highlight the importance of Chamorro’s discoveries in the fields of endocrinology, gynaecology, reproduction and oncology. Methods: Evaluation of the bibliometric impact of Chamorro’s work using Google Scholar, PubMed, Scopus and Gallica. Results: Between 1937 and 1945 Chamorro carried out important research work, the results of which provided valuable discoveries about the activity of the main endocrine glands. Discussion: To achieve our objective, Google Scholar has been the most profitable metasearch engine from a practical point of view, having recognized almost all of the articles published by Chamorro, although having ignored some of them it could be thought that the overall impact of this author is higher than that which has been found. Conclusions: These findings were reflected in the most prestigious journals and widely disseminated in U.S. research institutions, amongst others. In Spain, however, they were ignored. Maybe it’s time to spread it.
