In 1964, two new types of apogamy were described in ferns. The sporangia contain at the starting-point 16 spore mother cells and at the endingpoint 32 diplospores. On the one hand, the meiosis is replaced by a mitosis, on the other hand, the first meiotic division aborts and the restituition nucleus divides mitotically. The author's observations imply that the second process is a variant of the first one.

The aim of this paper is to study a set of three issues related to the understanding of partial justice and partial injustice as character dispositions, namely the distinctive circumstance of action, the emotion involved therein and the pleasure or pain following it. Those points are treated in a relatively obscure way by Aristotle, especially in comparison with their treatment in the expositions of other character virtues in the Nicomachean Ethics. Building on the expression ‘capacity towards the other’ (δύναμις ἐν τῷ πρὸς ἕτερον), the paper highlights the interpersonal nature of the circumstances of just and unjust actions, and points how such nature is directly related to notions such as ‘profit’ (κέρδος) or ‘getting more’(πλεονεκτεῖν) as well as to the unusual conception of excess, defect and intermediacy in Nicomachean Ethics Book V. The interpersonal nature of just and unjust actions works also as the starting-point for the interpretation both of the pleasure briefly mentioned in 1130b4 as characterizing the greedy person and of the emotion involved in acting justly or greedy, which is mentioned in an extremely elliptical way in 1130b1-2: the paper argues, on the one hand, that the pleasure felt in acting justly or unjustly concerns not only the goods that are the object of just or unjust interactions, but also the way such interactions affect the people involved; on the other hand, it argues that the emotion actuated in just or unjust interactions relates to the agent’s concern or lack of concern with the good of those people.

The article is devoted to the famous The Discourse of Voluntary Servitude by Étienne de La Boétie. The author considers the theoretical premises underlying the concept of “voluntary servitude”, juxtaposing them with two modern concepts of will developed by Descartes and Pascal. An important feature of La Boétie’s project is the political and therefore intersubjective – as opposed to the individualistic perspective of Descartes and Pascal – starting point. It is therefore situated against the background of, on the one hand, the historical evolution of early modern states (from feudal monarchies, through so-called Renaissance monarchies up to European absolutisms) and, on the other hand – of the political philosophy of Machiavelli and Hobbes.

The aim of this article is to trace the referential value of juffrouw Lina (1888)as part of its narrative organisation by means of the narrativist historical theoryof Frank Ankersmit. This starting point demands a confrontation of thisnaturalist novel by Marcellus Emants with the contemporary medical biographyof the French writer and politician Chateaubriand by the Belgian physicianErnest Masoin on the one hand and with some case studies of hystericsby the famous French docter Jean-Martin Charcot on the other hand. lt willbe argued that the narrativity of the novel plays a key-role in the constructionof its referential value on various levels.

AbstractTacitus and Sima Qian (ca. 140-85 BC, author of the Shiji, the Records of the Historian) are eminent representatives of Roman and ancient Chinese historiography. The starting-point of the paper is a striking parallel between the two historians: During the reign of autocratic emperors (of the last of the Flavian emperors, Domitian, and of the most powerful of the Han-emperors Wudi) both authors undergo experiences which not only affect them on a personal level, but also influence their historiographie practice. The paper traces this influence with respect to the representations of individual historical characters. On the one hand it analyses the representations of rulers: of Tiberius, adoptive son and successor of Augustus, and of Wendi, natural son and (indirect) successor of Gaodi, the founder of the Han-dynasty; on the other hand it studies the representations of second and third rank characters such as senators, ministers, generals, and - in the case of Sima Qian - also of people from other walks of life. The similarities which can be observed between the two authors point to the existence of certain anthropological constants, whereas the differences are to be attributed to basic differences in Roman and Chinese political thinking and to differing degrees of the intensity of the experiences undergone by each historian.

Abstract This study takes a lexical-grammatical approach to exploring the evaluation of human behaviour and/or character. It uses adjective complementation patterns as the starting point to examine the lexical-grammatical resources at risk in the appraisal system of judgement, aiming to explore the extent to which we can arrive at the same categorization of the resources realizing judgement if a formal or lexical-grammatical approach, rather than a discourse-semantic one, is taken. Using a corpus compiled of texts categorized as ‘Biography’ in the British National Corpus, the study, on the one hand, shows that most of the items identified can be very satisfactorily classified in terms posited in the judgement system, suggesting that the nomenclature from that model is useful. On the other hand, a considerable number of items have also been identified which construe attitudes towards emotional types of personality traits, leading to the proposal of a potentially useful new judgement category and further an adjusted system of judgement. The heuristic potential of aligning the lexical-grammatical and discourse-semantic approaches to appraisal is further discussed.

Abstract The article criticizes some shortcomings of Asian contextual and liberation theologies that methodologically employ ‘hermeneutical circle’. The method focuses on experience as the starting point of doing theology. Despite its powerful insights that enable theologians to engage with concrete human and social problems, the method can easily preserve a theologian’s blind spot that hinders her/him from perspectives other than his or her own. I also criticize such an experience-based method as being too linear which can easily result in a methodological imperialism. In response to the weakness, I propose a multitextual theology, which on the one hand acknowledges the importance of perspectivism in any theology but also, on the other hand, celebrates theological freedom in viewing reality from ‘manywheres’. Since reality provides plurality of texts, a multitextual theology can begin simultaneously from any text, without being trapped into a procedural rigidity as clearly demonstrated in contextual and liberation theologies.

PurposeAlthough the market for communication consultancies has been booming worldwide for many years now, there are still only a handful of theoretical concepts and empirical findings pertaining to communication consulting. This is the fundamental starting point for this paper, which sets out to answer the following research questions: What is the function of communication consulting? What are the differences between consultants' expectations of consulting and those of clients? How do consultants and clients deal with the contradiction between proximity and distance? What are the potential threats to the autonomy of consulting?Design/methodology/approachThe paper combines a theoretical framework of communication consulting with a survey of German communication consultants and clients.FindingsFirst, a theoretical framework is developed in which communication consulting is defined as follows: First, it opens up decision-related contingency and thus produces additional options for managing communicative relationships with internal and external target groups, before helping to close decision-related contingency. The results of the survey show that the expectations of clients and consultants for communication consulting are largely similar. In the closing dimension especially, most clients share the active role of self-conception of most consultants. On the other hand, in some opening activities, clients wish for more critical, independent and courageous consulting.Research limitations/implicationsThe scope of the empirical material is limited to communication consultants and clients in Germany and may therefore not be valid in other cultural contexts.Originality/valueThe paper closes a gap in both theory building and empirical research in communication consulting. The theory presented conceives of communication consulting as a hybrid of management consulting and process consulting and, in addition to the opening dimension, also takes the closing dimension of consulting into consideration for the first time. The study reveals a certain schizophrenia in clients: on the one hand, clients demand more critical consultants and thus call for more distance; on the other hand, clients prefer to be close to their consultants, particularly if they wish to work with them for the long-term.

Patent claims define the protection scope of the intellectual property sought by the patent applicant or patentee. Broad claims are valuable as they can describe more expansive rights to the invention. Therefore, if these claims are too broad a potential infringer will more easily argue against them. But if the claims are too narrow the scope of protection of the intellectual property is greatly reduced. Patent claims have to be, on the one hand, determinate and precise enough and, on the other hand, as inclusive as possible. Therefore patent applicants must find a balance in the broadness of the scope defined by their claims. This balance can be achieved by the choice of words with a convenient degree of semantic indeterminacy, by the choice of modifiers or other strategies. In fact, vagueness in patent claims is a desirable characteristic for such documents. A quantitative and qualitative analysis of a corpus of 350 U.S. patents provides a promising starting point to understand the linguistic instruments used to achieve the balance between property claim scope and precision of property description. To conclude, some issues relating vagueness and pragmatics are suggested as a line of further research.

SummarySince many researchers and managers think about the essence, creation mechanisms and limits of the manufacturing model maturity, at this point, the author raises the question related to this issue: what dimensions (descriptions and desiderata) should be considered when conceptualizing this idea? The formulated question became a starting point and a point of conducting a creative synthesis, based, on the one hand, on a detailed analysis of the problem theory, and on the other hand – on the author’s own research. The above question and belief related to the existence of economic demand for results of application nature were the main inspiration to undertake research whose main purpose is to recognize: how the maturity of the business model is understood by selected experts operating in the Polish agricultural machinery sector?

It is inevitable that the rules for using various sources of information in cyberspace keep changing. We are still searching for the best possible form. A form that would, on the one hand, provide us with reliable material, and on the other hand guarantee utmost security and ensure that our interests or any exchange of correspondence or opinion will not be seized by unauthorised individuals or even used against us. In order to meet such needs and expectations, Darknet has been created, in particular TOR network (The Onion Router). The starting point for this paper was the history and principles of TOR, as well as the issue of anonymity and payments with cryptocurrencies. In the further part of the article there is a discussion on the positive and negative opportunities that TOR offers. The paper ends with an indication of possible directions for further work and elaboration.
