Different Cultures

AbstractComparative writing about the history of science and technology in different cultures tends to assume that differences in the ways in which these cultures write their histories are not important. But this is unlikely to be the case. The comparative lack of historical writing about printing in China by European standards should not in itself lead us to conclude that print only played a minor role there, any more than the tendency to downplay the importance of paper among historians of the European book means that its use in Europe was less significant than in other cultures. That in China the relative balance of the historical record is the opposite of the one that we tend to assume on the basis of the European experience is demonstrated here by contrasting the dearth of information about early printing with the commemoration even of relatively marginal cultural figures through the traditional Chinese historiography of paper making. But only tentative suggestions can be made as to why these differences in historical writing may have occurred.

SummaryAn analysis of the results of prothrombin time tests with different types of thromboplastins sheds some light on the problem why the administration of coumarin is difficult to standardize in different centers. Our present ideas on the subject, based on experimental data may be summarized as follows.Several factors of the clotting mechanism are influenced by coumarin derivatives. The action of some of these factors is by-passed in the 1-stage prothrombin time test. The decrease of the prothrombin and factor VII levels may be evaluated in the 1-stage prothrombin time determination (Quick-test). The prolongation of the prothrombin times are, however, predominantly due to the decrease of factor VII activity, the prothrombin content remaining around 50 per cent of normal during an adequate anticoagulant therapy. It is unlikely that this degree of depression of prothrombin is of major significance in interfering with the coagulation mechanism in the protection against thromboembolism. It may, however, play a minor role, which has yet to be evaluated quantitatively. An exact evaluation of factor VII is, therefore, important for the guidance of anticoagulant therapy and the method of choice is the one which is most sensitive to changes in factor VII concentration. The 1-stage prothrombin time test with a rabbit lung thromboplastin seems the most suitable method because rabbit brain preparations exhibit a factor VII-like activity that is not present in rabbit lung preparations.

Social Utopia

This paper is an interdisciplinary analysis of Friedrich Schiller’s play Wilhelm Tell (1804). An initial study of its dramatic structure suggests a change in the relationship between the Swiss peasants and nobles. A further analysis, based on Brown’s and Levinson’s politeness theory confirms the development of a social utopia in the play, but also reveals that Wilhelm Tell plays a minor role in the social development described. The comparison of the play with earlier versions of the Tell legend highlights the roles of peasants and nobles in the establishment of the Swiss Confederation and suggests that Schiller elaborated extensively on the idea of a ‘common ground’ among the Swiss from different classes. The comparison between Schiller’s play and the contemporary German philosopher Johann Benjamin Erhard’s essay Über das Recht des Volks zu einer Revolution illustrates that Schiller’s social utopia develops in accordance with contemporary social visions. However, Tell’s act of murder separates him from the other Swiss protagonists in Schiller’s attempt to outline a righteous revolution, different from the one in France.

To Receive

Recently, the role of the victim in criminal proceedings became more significant. An observation was made that the legal interests of the victim are much more severely affected by the crime than the collective legal interests in the form of public or social order. However, the differences in the rights the victim is vested with differ substantively between particular countries. The authors present the position of the victim in American, English and French law. The solutions provided for in these systems are confronted with legal regulations adopted in Poland, i.e. the home country of the authors. It shows, surprisingly, that the role of the victim in criminal proceedings has evolved somehow independently of the implementation of the concept of restitution. On the one hand, there are legal systems in which the criminal court may order the offender to pay compensation for the damage caused, but the role of the victim still remains marginal. On the other hand, there are systems in which the victim is not only entitled to receive restitution, but he or she also has significant powers which enable him or her to play an active role in the criminal proceedings.

AbstractThis article has two goals. It reflects on the recent developments and agenda of an approach to historical writing that is now becoming known by the name global microhistory, and it analyses the attention which this approach pays to individual lives. It also explores some of the challenges in writing the biography of a city alongside the life history of a person. The city is Harbin, a former Russian-managed railway hub in Manchuria, today a province capital in Northeast China. The person is Baron Roger Budberg (1867–1926), a physician of Baltic German origin who arrived in Harbin during the Russo-Japanese war and remained there until his death, leaving published works and unpublished correspondence in German and Russian. My forthcoming book about Budberg and Harbin challenges the distinction between writing “biography”, on the one hand, and “history”, on the other, while navigating between the “micro” and “macro” layers of historical enquiry.

The work reported here was done to explore the extent to which the mature weight of a grain is determined by (i) its potential for growth, defined as its intrinsic capacity to accumulate dry matter, and (ii) the resistance to assimilate transport imposed by the vascular system of the ear. Estimation of growth potential was attempted by observing the effects of systematic patterns of grain removal on the mature weights of grains remaining, these being compared with weights of matched grains from intact ears. Resistance to transport of assimilate was inferred from the apparent order of priority between grains for the supply of assimilate, as revealed by comparing their weights when assimilate supply was either normal, or reduced by plant shading. When neighbouring grains were removed, those remaining usually grew larger to an extent that indicated growth potential appreciably in excess of that utilized in intact ears under the most favourable conditions. Although grains within a spikelet of an intact ear attain quite different weights, the experiments suggested that their differing potentials for growth seemed to play only a minor role in this, and that the major influence was the relative ease with which assimilate could reach the grains; this depended largely on the distance of the grains from the spike rachis. Comparing between spikelets, the difference found in intact ears between grains in the same spikelet location tended to persist when some grains were removed from each spikelet, indicating a possible role of growth potential as a controlling influence. This may be partly due to the sequence of morphogenesis, established as early as the double ridge stage. Although the removal of competing grains within a spikelet usually enhanced the growth of the one remaining, this was not always so; there was evidence from one experiment that removal of competing grains towards the spikelet apex represented the removal of some beneficial influence. The bearing of the results on possible limitations to grain yield are discussed.

This paper presents effects of dispersion on predicting longitudinal ammonia concentration profiles in activated sludge bioreactor located at “Wschod” WWTP in Gdansk. The aim of this study was to use the one-dimensional advection-dispersion Equation (ADE) to simulate the flow conditions (based on the inert tracer concentrations in selected points) and longitudinal profile of reactive pollutant (based on the ammonia concentration profiles in selected points). The simulation results were compared with the predictions obtained using a traditional “tanks-in-series” (TIS) approach, commonly used in designing biological reactors. The use of dispersion coefficient calculated from an empirical formula resulted in substantial differences in the tracer concentration distributions in two sampling points in the bioreactor. Simulations using the one-dimensional ADE and TIS model, with the nitrification rate incorporated as the source term, revealed that the hydraulic model plays a minor role compared to the biochemical transformations in predicting the longitudinal ammonia concentration profiles.

AbstractIn the growth of thin films of compound semiconductors on (001) silicon substrates by vapor deposition techniques, it is usual to employ a two-step process. In this method, an initial (buffer) layer is first grown at a relatively low temperature; once a continuous film has formed on the substrate, its temperature is raised for the subsequent bulk growth. Carrying out the growth in a one-step process by heating the substrate to the final temperature before allowing the gases into the CVD reactor usually results in a polycrystalline aggregate. In this paper, classical nucleation and growth mechanisms are used to explain-the reasons for the different morphology of the one-step and two-step growth films.The heteroepitaxial films on (001) silicon often contain a high density of stacking faults and twins. The occurrence of these planar defects is usually attributed to stresses that arise from lattice mismatch and/or thermal mismatch (differences in coefficients of thermal expansion) between the substrate and the epilayer. It is argued that, in fact, mismatch stresses play a minor role in the generation of planar defects. Instead, an alternative mechanism for their formation is proposed which is based on the facetted shape of nuclei and errors in stacking of {111} planes which occur during deposition on the facets.Conventional and high resolution transmission electron microscopy have been used to investigate three systems grown by CVD or MOCVD: SiC/Si, GaAs/Si and GaP/Si. These systems have different lattice and thermal mismatches, and the results support the proposed model for the formation of defects.

ABSTRACT In order to examine the natural history of metal homeostasis genes in prokaryotes, open reading frames with homology to characterized PIB-type ATPases from the genomes of 188 bacteria and 22 archaea were investigated. Major findings were as follows. First, a high diversity in N-terminal metal binding motifs was observed. These motifs were distributed throughout bacterial and archaeal lineages, suggesting multiple loss and acquisition events. Second, the CopA locus separated into two distinct phylogenetic clusters, CopA1, which contained ATPases with documented Cu(I) influx activity, and CopA2, which contained both efflux and influx transporters and spanned the entire diversity of the bacterial domain, suggesting that CopA2 is the ancestral locus. Finally, phylogentic incongruences between 16S rRNA and PIB-type ATPase gene trees identified at least 14 instances of lateral gene transfer (LGT) that had occurred among diverse microbes. Results from bootstrapped supported nodes indicated that (i) a majority of the transfers occurred among proteobacteria, most likely due to the phylogenetic relatedness of these organisms, and (ii) gram-positive bacteria with low moles percent G+C were often involved in instances of LGT. These results, together with our earlier work on the occurrence of LGT in subsurface bacteria (J. M. Coombs and T. Barkay, Appl. Environ. Microbiol. 70:1698-1707, 2004), indicate that LGT has had a minor role in the evolution of PIB-type ATPases, unlike other genes that specify survival in metal-stressed environments. This study demonstrates how examination of a specific locus across microbial genomes can contribute to the understanding of phenotypes that are critical to the interactions of microbes with their environment.

The article presents a theoretical analysis of modern theories of wisdom, considers the formation and essence of the concept of wisdom in psychology. At the end of the twentieth century, the interest of psychologists in the subject of wisdom began to grow. Wisdom as a concept is integral to any society, culture and time, it reveals those qualities of personality that help a person to be realized. The concept of wisdom requires theoretical justification and empirical research. In general, there are two main concepts of wisdom: one affirms the affective qualities more or less with the cognitive, inherent in man; the other focuses precisely on cognitive and reflexive abilities, ignoring emotional life. This typification has proved itself in several planes. In the history of philosophy, the understanding of wisdom had both an affective and a cognitive character, represented by East and West. Empirical studies of implicit concepts of wisdom conducted in recent years indicate the variability of perception of wisdom. In the East, the concept of wisdom is less analytical and more psychological than in the West, which requires an understanding not only of the intellectual, but also of the sensual (emotions, intuition, etc.). Cross-cultural empirical studies confirm the general difference in the perception of wisdom in different cultures. The influence of age on the manifestations of wisdom in humans should be noted separately. Research has shown that age negatively affects the intellectual component of wisdom, but is neutral to procedural knowledge. On the one hand, with age a person acquires experience that can interpret and extract new procedural knowledge from him. On the other hand, the fact that a person has life experience does not determine a person’s qualitative interpretation of what happened to him. The age factor cannot be decisive in becoming wise.

The Impact

For conversational agents’ speech, either all possible sentences have to be prerecorded by voice actors or the required utterances can be synthesized. While synthesizing speech is more flexible and economic in production, it also potentially reduces the perceived naturalness of the agents among others due to mistakes at various linguistic levels. In our article, we are interested in the impact of adequate and inadequate prosody, here particularly in terms of accent placement, on the perceived naturalness and aliveness of the agents. We compare (1) inadequate prosody, as generated by off-the-shelf text-to-speech (TTS) engines with synthetic output; (2) the same inadequate prosody imitated by trained human speakers; and (3) adequate prosody produced by those speakers. The speech was presented either as audio-only or by embodied, anthropomorphic agents, to investigate the potential masking effect by a simultaneous visual representation of those virtual agents. To this end, we conducted an online study with 40 participants listening to four different dialogues each presented in the three Speech levels and the two Embodiment levels. Results confirmed that adequate prosody in human speech is perceived as more natural (and the agents are perceived as more alive) than inadequate prosody in both human (2) and synthetic speech (1). Thus, it is not sufficient to just use a human voice for an agents’ speech to be perceived as natural—it is decisive whether the prosodic realisation is adequate or not. Furthermore, and surprisingly, we found no masking effect by speaker embodiment, since neither a human voice with inadequate prosody nor a synthetic voice was judged as more natural, when a virtual agent was visible compared to the audio-only condition. On the contrary, the human voice was even judged as less “alive” when accompanied by a virtual agent. In sum, our results emphasize, on the one hand, the importance of adequate prosody for perceived naturalness, especially in terms of accents being placed on important words in the phrase, while showing, on the other hand, that the embodiment of virtual agents plays a minor role in the naturalness ratings of voices.
