Three groups of men were tested in a situation involving reaction to two successive stimuli at a short known time interval. Each reaction required the choice of one of two reaction keys, depending upon the light stimulus delivered. For one group of subjects, the first reaction was made easy by making the left key correct for the left light; for the second group, the first reaction was made slower by making the left key correct for the right light. In the third group, one of the two possible stimuli for the first reaction occurred more often than the other, so that the first reaction was sometimes fast and sometimes slow. The second reaction was delayed if the interval between stimuli was shorter than the first reaction time; in conditions where the first reaction time was longer, the second reaction time was delayed by an even greater amount. This result supports the view that a common decision-making mechanism of limited capacity is occupied by the first reaction and so is unable to deal with the second one; two other theories of the effect seem inconsistent with the present data.

Abstract Materials from topographic surveys had a serious impact on the labels on the maps that were based on these surveys. Collecting toponyms and information that were to be placed as labels on a final map, was an additional duty the survey officers were tasked with. Regulations concerning labels were included in survey manuals issued by the Austro-Hungarian Militärgeographisches Institut in Vienna and the Polish Wojskowy Instytut Geograficzny in Warsaw. The analyzed Austro-Hungarian regulations date from the years 1875, 1887, 1894, 1903 (2nd ed.). The oldest manual was issued during the Third Military Survey of Austria-Hungary (1:25,000) and regulated the way it was conducted (it is to be supposed that the issued manual was mainly a collection of regulations issued prior to the survey launch). The Third Survey was the basis for the 1:75,000 Spezialkarte map. The other manuals regulated the field revisions of the survey. The analyzed Polish manuals date from the years 1925, 1936, and 1937. The properties of the labels resulted from the military purpose of the maps. The geographical names’ function was to facilitate land navigation whereas other labels were meant to provide a military map user with information that could not be otherwise transmitted with standard map symbols. A concern for not overloading the maps with labels is to be observed in the manuals: a survey officer was supposed to conduct a preliminary generalization of geographical names. During a survey both an Austro-Hungarian and a Polish survey officer marked labels on a separate “label sheet”. The most important difference between the procedures in the two institutes was that in the last stage of work an Austro-Hungarian officer transferred the labels (that were to be placed on a printed map) from the “label sheet” to the hand-drawn survey map, which made a cartographer not responsible for placing them in the right places. In the case of the Polish institute the labels remained only on the “label sheets”.

Abstract Females of Drosophila melanogaster and its sibling species D. simulans have very different cuticular hydrocarbons, with the former bearing predominantly 7,11-heptacosadiene and the latter 7-tricosene. This difference contributes to reproductive isolation between the species. Genetic analysis shows that this difference maps to only the third chromosome, with the other three chromosomes having no apparent effect. The D. simulans alleles on the left arm of chromosome 3 are largely recessive, allowing us to search for the relevant regions using D. melanogaster deficiencies. At least four nonoverlapping regions of this arm have large effects on the hydrocarbon profile, implying that several genes on this arm are responsible for the species difference. Because the right arm of chromosome 3 also affects the hydrocarbon profile, a minimum of five genes appear to be involved. The large effect of the third chromosome on hydrocarbons has also been reported in the hybridization between D. simulans and its closer relative D. sechellia, implying either an evolutionaly convergence or the retention in D. sechllia of an ancestral sexual dimorphism.

- The article summarizes the results of a research conducted on the social policies change in Naples, particularly in Scampěa and in North Area of the city. This change saws the active involvement of the third sector organizations in the process of implementation of policies. The survey pays special attention to the process of welfare networking developed in the Area, although this involved a deep reconsideration, on the part of researchers, about the risks of contamination of the research as subject get closer. The involvement of an Association, among those most active in the area, while allowed more direct understanding of decision making, on the other hand became a strong pressure. Mediation among the scientific aims and those expressed by the Association led to a deviation of the original research design.Key words: social policies, suburbs, poverty, school dropout, voluntary, welfare

Humans have learned to cooperate in many ways and in many environments, on different tasks, and for achieving different and several goals. Collaboration and cooperation in their more general sense (and, in particular, negotiation, exchange, help, delegation, adoption, and so on) are important characteristics - or better, the most foundational aspects - of human societies (Tuomela, 1995). In the evolution of cooperative models, a fundamental role has been played by diverse constructs of various kinds (purely interactional, technical-legal, organizational, socio-cognitive, etc.), opportunely introduced (or spontaneously emerged) to support decision making in collaborative situations. The new scenarios we are destined to meet in the third millennium transfigure the old frame of reference, in that we have to consider new channels and infrastructures (i.e., the Internet), new artificial entities for cooperating with artificial or software agents, and new modalities of interaction (suggested/imposed by both the new channels and the new entities). In fact, it is changing the identification of the potential partners, the perception of the other agents, the space-temporal context in which interaction happen, the nature of the interaction traces, the kind and role of the authorities and guarantees, etc. For coping with these scenarios, it will be necessary to update the traditional supporting decision-making constructs. This effort will be necessary especially to develop the new cybersocieties in such a way as not to miss some of the important cooperative characteristics that are so relevant in human societies.

The principal objective of the study was to examine the effect of Telfast® 180, an antihistamine, on driver behaviour, decision-making, and reaction time. A sample of 255 volunteers participated in the study. The sample was randomly divided into two groups, viz. a placebo and a Telfast group. One of the groups received Telfast and the other a placebo. Initially all the participants were given a standardised driving test, as well as a psychomotor test. Immediately thereafter the placebo group received their placebo tablets and the Telfast group their Telfast tablets. Exactly 2,6 hours later every participant was tested again, using the same tests as before. No statistically significant differences were found between the Placebo group and the Telfast group. No sedative effects due to Telfast® 180 were thus evident. Opsomming Die hoofdoelstelling van die studie was om die effek van Telfast® 180, ’n antihistamien, op bestuursgedrag, besluitneming en reaksietyd, te ondersoek. ’n Steekproef van 255 vrywilligers het aan die studie deelgeneem. Die steekproef is lukraak in twee groepe verdeel, te wete ‘n plasebogroep en ’n Telfastgroep. Om mee te begin is al die deelnemers aan ’n gestandaardiseerde bestuurstoets, asook ’n psigomotoriese toets, onderwerp. Onmiddellik daarna het die plasebogroep hul plasebotablette en die Telfastgroep hul Telfasttablette ontvang. Presies 2,6 uur later is al die deelnemers weer getoets met dieselfde toetse as voorheen. Geen statisties beduidende verskille is tussen die plasebogroep en die Telfastgroep gevind nie. Daar was dus geen sedatiewe effek as gevolg van Telfast® 180 nie.

One of the brightest of the Third Programme's recent efforts was the presentation of a little festival of Pfitzner's music. “Little,” perhaps, may be not quite the right word for however short a series of programmes which included the whole of Palestrina (1912–1915), but it must be remembered that Pfitzner wrote four other operas besides this celebrated chef-d'oeuvre—Der arme Heinrich (1891–93), Die Rose vom Liebesgarten (1897–1900), Das Christelflein (1906, revised 1917), and Das Herz (1930–31). The B.B.C. gave us no glimpse of these other operas, although round about Christmas of each year one of their regional orchestras undertakes the overture to Das Christelflein as an appropriately seasonal piece. For this festival occasion, the B.B.C, in addition to Palestrina, threw in a song recital and a performance of Pfitzner's last chamber work, the Sextet (Op. 55/1945) for piano, violin, viola, cello, double-bass and clarinet. These two latter items may have been well-intentioned choices, but, notwithstanding, they were extremely ill chosen. The Third Programme—as, alas, so often—was either wrongly advised, or simply did not have any (skilled) advice to call upon. For instance, the six songs, ably performed by Mary Jarred, belonged to Pfitzner's earliest period—the latest “Lied”" was Sonst (Op. 15, no. 4), composed in 1904, and most of the other songs were written in the 1880's or 90's. But Pfitzner's output of “Lieder” extends to the 1930's and up to Op. 41—and his maturest and best songs are to be found in the years which the B.B.C. did not remotely approach! Incidentally, no opus numbers were printed in the Radio Times or announced over the air, so that as far as the uninformed listener was concerned he was hearing a “representative” selection of Pfitzner's “Lieder”; in fact, of course, he was hearing nothing of the kind.

The European Union membership referendum (i.e. the Brexit referendum) in the United Kingdom in 2016 triggered a process of introspection among non-British European Union citizens with respect to their right to remain in the United Kingdom, including their right to entry, permanent residence, and access to work and social welfare. Drawing on interview data collected from 42 European Union nationals, namely Finnish and Polish migrants living in Scotland, we explore how European Union migrants’ decision-making and strategies for extending their stay in the United Kingdom, or returning to their country of origin, are shaped by and, in turn, shape their belonging and ties to their current place of residence and across state borders. In particular, we draw on the concept of embedding, which is used in migration studies to explain migration trajectories and decision-making. Our key argument is that more attention needs to be paid to the socio-political context within which migrants negotiate their embedding. To this end, we employ the term ‘politics of embedding’ to highlight the ways in which the embedding of non-British European Union citizens has been politicized and hierarchically structured in the United Kingdom after the Brexit referendum. By illustrating how the context of Brexit has changed how people evaluate their social and other attachments, and how their embedding is differentiated into ‘ties that bind’ and ‘ties that count’, we contribute to the emerging work on migration and Brexit, and specifically to the debate on how the politicization of migration shapes the sense of security on the one hand, and belonging, on the other.

7 schizophrenics and 8 normal controls were administered reaction time (RT) trials while alpha (8 to 13 cps) waves were visible from the right motor parietal EEG leads. Under these conditions, schizophrenics were significantly faster than normals in alpha blocking latency (ABL) on this and the other two recorded channels. No differences occurred in RT. Mean RT was significantly correlated with mean ABL only when blocked trials and diminished trials were correlated separately. Intrasubject correlations between RT and ABL were not significant. The findings were discussed in terms of the concepts of arousal by Venables and by Goldstein and Sugerman.

Purpose. The article is dedicated to the analysis of the main changes introduced by the Law of Ukraine “On Amendments to Some Laws of Ukraine ensuring the principles of procedural justice and increasing the efficiency of proceedings in cases of violations of the legislation on the protection of economic competition”. Methods. Law of Ukraine “On Amendments to Some Laws of Ukraine ensuring the principles of procedural justice and increasing the efficiency of proceedings in cases of violations of the legislation on the protection of economic competition” proposes the implementation of several novelties. Among them are: the restriction for the Antimonopoly Committee of Ukraine by certain time limits for considering cases; possibility of extension of the term for consideration of cases by decision of the Committee’s State Commissioner or head of a territorial office; renewal of deadlines for consideration of cases where the respondent is replaced or a co-respondent is involved; provision for the consequences of missing the deadlines for considering cases and also the mechanism of consultations during the consideration of a case, which may be appointed either on the initiative of the Antimonopoly Committee of Ukraine or on the motion of interested persons. Results. The abovementioned amendments will influence the existing system of economic competition protection in a serious way. Among the changes are: – the fine for delayed payment of a fine imposed by the Antimonopoly Committees of Ukraine decision on violation of the legislation on the protection of economic competition is cancelled; – the member of the Antimonopoly Committee of Ukraine who conducted or organized an investigation is deprived of the right to vote in the process of decision-making in the respective case; – the procedure for holding hearings is defined; – recusals and self-recusals are envisaged for the Antimonopoly Committee of Ukraine officers; – the grounds for acquiring the third-party status in a case are changed; – the rights of persons involved in the case are specified and expanded. An important remark of the Law of Ukraine “On Amendments to Some Laws of Ukraine ensuring the principles of procedural justice and increasing the efficiency of proceedings in cases of violations of the legislation on the protection of economic competition” is that a person that is exempted from liability or whose fine is reduced shall still be liable for damage caused by the violation to other persons. Conclusions. As a result, Law of Ukraine “On Amendments to Some Laws of Ukraine ensuring the principles of procedural justice and increasing the efficiency of proceedings in cases of violations of the legislation on the protection of economic competition” is expected to become an important step forward in increasing the effectiveness of investigations into violations of the legislation on the protection of economic competition. It can also be regarded as the next step to harmonize Ukrainian legislation with the European Union acquis.
