The problem of the description of artificially present industrial noises which are available at operation of personal computers is considered in work. These noises have both positive and negative effects when protecting the information typed by the user by means of the USB keyboard interface. The difficulties that arise in this case are due to the fact that the indirect radiation of electromagnetic fields is observed during the operation of all elements of computer technology. On the one hand, the presence of these noises distorts the useful signal, which in turn prevents the attacker from detecting reliable information that is transmitted. On the other hand, these noises prevent the creation of appropriate measures to ensure complete protection when typing by a user of a personal computer. The paper proposes to consider industrial noise in the form of three random processes, which are described by Johnson distributions.

Abstract Breeding output of geese, measured as the proportion of juveniles in autumn or winter flocks, is lower in years with a late onset of spring in some species, but higher in at least one other species. Here we argue that this is because the timing of spring affects different stages of the reproductive cycle differently in different species. Because the effects on 2 different stages are opposite, the combined effects can result in either a positive or a negative overall effect. These stages are the pre-laying, laying, and nesting phase on the one hand; and the hatchling, fledgling, and juvenile phase on the other hand. The first phase is predominantly positively affected by an early snowmelt, with higher breeding propensity, clutch size, and nest success. The second phase in contrast is negatively affected by early snowmelt because of a mismatch with a nutrient food peak, leading to slow gosling growth and reduced survival. We argue that recognition of this chain of events is crucial when one wants to predict goose productivity and eventually goose population dynamics. In a rapidly warming Arctic, the negative effects of a mismatch might become increasingly important.

Among composers born in the 1950s, who witnessed the decline of the post-war avant-garde – together with its most cherished principle, integral serialism – the Finn Magnus Lindberg has produced some of the most challenging responses. It is tempting to attach considerable significance to Lindberg's national origins. Born in 1958, he belongs to a particularly vital generation of Finnish composers whose output extends from traditional symphonic forms to experimental creations involving electroacoustic and computer technology. On the one hand, they have benefitted from the example of composers (such as Aulis Sallinen) who emerged from Sibelius's shadow not only by founding a strong operatic tradition, but also by generating their own brand of orchestral music. On the other, several of the younger generation have continued the practice of studying abroad, though without sacrificing their independence from the European mainstream.


1. During 1933 two papers with the above title, the one by Schott and the other by Fock, were published. Schott in his paper criticizes the usual procedure adopted in the Quantum Theory for the estimation of the intensities of a spectrum line according to the classical formula of Hertz, viz.., 2 p ..2 /3 c 3 , where p is the electric moment of the distribution producing the spectrum line, which necessarily assumes that the distribution can be concentrated in a dipole of the same moment p. In view of this criticism he develops a more rigorous method for calculating the electromagnetic fields due to variable electric charges. His method is based upon Maxwell's theory, as represented by his elctromagnetic equations and their solutions in terms of the classical retarded potential integrals and no initial assumptions are made respecting the spatial extent or the rate of variation of the electric distributions considered.

Abstract This article draws on 22 interviews with Italian anti-speciesists to develop a sociological account of the quest for ethical consistency in the animal rights movement. The essay analyzes three relevant consequences of the search for consistency—identity extension, social segregation, and self-transformation—and discusses their impact on the activists’ lives. Consistency appears as both a source of self-gratification and a burden. On the one hand, self-gratification results from a sense of moral pride and the certainty of fighting for a just cause. On the other hand, the pursuit of a consistent lifestyle is highly demanding in terms of time and energy, and can have negative effects on the activist’s relationships with family and peers. While the paper adopts an individual-level perspective, it also examines how the findings might relate to vegan mobilization. It is argued that the findings might be generalizable to activists in other countries who face similar challenges.

A hypothetical proposition is stated that mythologization of objects in M. Garetsky’s works is a way to harmonize the surrounding world and man in it, and also a precise picture of the reality, a sign of changes and calamities.In accordance with M. Garetsky’s mythopoetical concept, the tragic spirit of human life is vivid in simultaneous personi­ fication of objects and objectivation of people; it is revealed in such moments as hiding face (“Winter”), or partial identification of man with clothes (“Guiet current”). Complete and irrevocable objectivation of man is presented by the author in the story “Winter” and the novel “Guiet current”.In the story “Winter” the central place, or a scene where objects attack man is a mythological image of a house, which fulfills various content and conceptual functions in the author’s mythmaking. On the one hand, the house is a protective hearth, which gives man complete protection, like in the stories “In a Sauna”, “Native Root”. On the other hand, it is a place of uncomfortable and constrained human life.It is stressed that in M. Garetsky’s descriptions we see a transition from life precision to dethronement of social myth. There is a similar fine line between life plane and myth in the story “In a Sauna”, but this work, unlike the story “Tar”, depicts not destruction of myth, but its growth and reinforcement, which is symbolically revealed in sentences and in magical charms (the story “Winter”).

The discourse of globalization and its effects have been the most current topic in the field of economics in recent times. However, empirical research on the impact of globalization on companies, especially in transition countries, is very scarce. This paper focuses on the study of the impact of globalization on the performance of companies in Bosnia and Herzegovina by analyzing their interrelationships. The findings, in the case of companies in Bosnia and Herzegovina, have confirmed earlier findings about the double impact of globalization by showing, on the one hand, its positive effects and, on the other hand, the negative effects on the performance of the companies. Additionally, the research results have shown that negative effects are felt more strongly in the case of small and medium-sized companies than in the case of large companies.

The different interpretations of the holy texts of the Qur'an further broaden the horizon of Muslim understanding of the content of God's messages on the one hand. But on the other hand, the greater the interpretation if not accompanied by an attitude of openness will lead to idiologization (talwiin) to certain understandings arising from that interpretation. Such an idiologisation will elicit a blind and faithless fanatic attitude in religion. Violence in the name of religion and the various conflicts among fellow Muslims recorded in the history of Islam from the past until now is concrete evidence of the negative effects of an interpretation. Therefore this paper is present to provide a comprehensive picture of the recitation of the Qur'an.  Keywords: Al-Qur'an, Contemporary Tafsir, Interpretation  Abstrak Perbedaan penafsiran terhadap teks suci al-Qur’an semakin memperluas horizon pemahaman umat Islam tentang kandungan pesan-pesan Tuhan di satu sisi. Namun di sisi lain, semakin banyaknya penafsiran tersebut apabila tidak dibarengi dengan sikap keterbukaan akan menimbulkan idiologisasi (talwiin) terhadap pemahaman-pemahaman tertentu yang muncul akibat penafsiran itu. Idiologisasi tersebut akan memunculkan sikap fanatik buta dan ketertutupan dalam beragama. Kekerasan atas nama agama dan berbagai konflik antar sesama pemeluk Islam yang tercatat dalam sejarah Islam dari dulu hingga sekarang adalah bukti kongkrit efek negatif sebuah penafsiran. Oleh karena itu tulisan ini hadir untuk memeberikan gambaran yang komprehensif terhadap pembacaan al-Qur’an.  Kata Kunci: Al-Qur’an, Tafsir Kontemporer, Penafsiran

Intellectual property rights have a twin effect on the economic system.On the one hand they increase the incentives to the introduction of new technologicalknowledge. On the other they increase the costs of the generation ofnew knowledge because they limit the access to an indispensable input such asexisting knowledge. A tradeoff between such positive and negative effects canbe formalized so as to identify of the ‘correct’ levels of knowledge rents...

Purpose – The purpose of this paper is to examine the impact of the Group Representation Constituency (GRC) system on the governance of Singapore, particularly in terms of equity and inclusiveness, accountability, and participation. Design/methodology/approach – Historical review and election data from Singapore government web site are used. Findings – The GRC system seems to be friendlier and fairer toward ethnic minorities than the traditional system. The GRC system also encourages political parties to be ethnically more inclusive. On the other hand, however, the GRC system has negative effects on opposition parties. A government cannot be called “accountable” if it lacks fair competition and sufficient popular participation. Originality/value – The Singapore experience shows that, in practice, ethnic equality/inclusiveness and even political stability on the one hand, and participation and accountability on the other hand, can present conflicts. Which value should receive priority thus requires serious consideration.

This paper studied the impact of free cash flow and capital structure on the performance of the company. It is based on the theories of the free cash flow and the capital structure, combined with the actual situation of China, using different property listed corporations’ sample, makes an empirical study on the impact of free cash flow and capital structure on the performance of the company. The result shows that on the one hand, having more free cash flow will cause negative effects on the performance of corporation, on the other hand, with the increase in liabilities financing, the listed corporation's performance fall.
