ABSTRACT Eleven plum cultivars (Prunus domestica L.) for processing grafted on semidwarf rootstock ‘Wangenheim Prune’ and vigorous rootstock ‘Myrobalan’ were densely planted (1000, 1250, 1666, 2500 trees ha-1) and trained to central leader spindle tree. A new training system was applied to obtain trees suitable for mechanical harvesting. The leader was not headed after planting and summer training procedures were performed in May/June. From the third year onwards, renewal pruning was carried out after fruit harvesting. The new training and pruning systems resulted in very fast tree growth, abundant branching, fruit bud formation on young wood and early bearing. The plum trees appeared to be suitable for hand and mechanical harvesting within 3 years from planting. The self propelled straddle combine harvester was able to harvest 2-3 tons of plums per hour compared to 30 kg with hand picking. Harvesting effectiveness was 90-95%. The quality of mechanically harvested plums was a little worse than of those hand picked, but fruits were suitable for processing. The ‘Common Prune’ and the prune type small plums were the most suitable fruit for mechanical harvesting.

The aim of this study was to evaluate phenology aspect, vigor, production and quality of ‘Eragil’ peach trees grown under different training and pruning systems. Evaluations were carried out during two seasons, 2015/16 and 2016/17. Fruit tree training and pruning systems ‘Open Center’ (3.5 × 5.0 m), ‘Ipsilon’ (1.5 × 5.0 m) and ‘Central Leader’ (0.8 × 5.0 m) were used. Phenology, vegetative growth (vigor) and yield were evaluated. ‘Central Leader’ plants showed a higher productivity and productive efficiency. ‘Open Center’ plants had a greater vigor and yield per plant, however had a lower yield by unit area. Plants with ‘Y’ shape were intermediates between ‘Open Center’ and ‘Central Leader’ in relation of the evaluated variables. ‘Central Leader’ training system can be used for peach orchards in order to increase yield and productivity indexes.

Abstract: The investigation is grounded on the idea of academic Ukrainian linguistic studies about the absence of active participles with the suffix -ч- in the Ukrainian national language of the XIX century and in the early stages of development of the modern Ukrainian literary language. The paper defines the origin and status of derivatives ending in -ч-(-ий) available in the vocabulary of the modern Ukrainian literary language. The object of study were three types of derivatives: 1) verbal adjectives with the suffix -уч- (-юч-), many of which are former participles that have lost morphological or accent correlation with verbs in the form of the 3rd person plural, and now they denote the attributes of objects or their inherent properties; 2) adjectives formed from qualitative adjectives with the suffixes -уч- (-юч-), -ач- (-яч-), which modify derivatives by word-forming meaning of intense manifestation of the quality; 3) active adverbial participle forms of the present tense with the suffix -ч-, which retain morphological or accent correlation with verbs in the form of the 3rd person plural and are mainly calques from Russian adjectives ending in -щ-(-ий), -ем-(-ый). The author substantiates the normality and expediency of the derivatives ending in -ч-(-ий), which belong to the first two groups and have become a means of expressing the quality of someone or something. At the same time, the author qualifies the derivatives of the third group as non-normative, as they contradict the morphological and word-formation norms of the Ukrainian literary language. This causes their replacement by adjectives with the suffixes -льн-, -івн-, -н- and other equivalent adjectives or complex nouns, which is especially noticeable in terminological systems, as well as in the common usage. These processes reflect the tendency to restore historically formed samples of Ukrainian adjective word formation and the consistent standardization of modern Ukrainian literary language on its national basis. Keywords: derivatives ending in -ч-(-ий), verbal adjectives with the suffix -уч- (-юч-), adjectives with the suffixes -уч- (-юч-), -ач- (-яч-), active present participles with the suffix -ч-, word-formation norm, the Ukrainian national language, the Ukrainian literary language.

  This paper deals with Fichte’s The Characteristics of the Present Age, and in particular with his discussion of the “empty form of knowledge” he claims stands at the centre of the third – i.e. the present – age. Fichte speaks of a fundamental principle that forms the ‘common denominator’ between the third and fourth main epochs. This fundamental principle – the “maxim of comprehensibility” (Maxime der Begreiflichkeit) – makes knowledge and comprehension the measure of all that “counts as being valid and as really existing”. But the question arises: How can one and the same principle act as the “unifying concept” for two different “main epochs of human life”? Does this not go directly against Fichte’s claim that two main epochs differ from each other in every respect, precisely because they arise from two entirely different “unifying principles”, and because everything in them must reflect the difference between their “unifying principles”? Fichte’s answer to this question is as follows:  a)  the fundamental maxim in question allows for two diametrically opposed interpretations, so that each of them provides the principle or the “unifying concept” from which the third and fourth main epochs arise, and b) the third main epoch only gives rise to the empty form of science, as opposed to “truly real science”: it stands for a careless and easy-going, shallow, conventional, trivializing and incorrect conception of the “fundamental maxim of comprehensibility” –  so that it misses what is essential, does not do justice to the fundamental maxim, overlooks its implications, and indeed goes against its innermost meaning. Special attention is paid to the question of whether and how some major features of Fichte’s “empty form of knowledge” result from a misguided and superficial understanding of Kant’s “maxims of the self-preservation of reason” and can be reconstructed from this vantage point.

Agnus is a Czech hybrid hop cultivar and a statistically significant influence of depth and term of pruning on harvested hop cones yield and on alpha-bitter acids content in hop cones were found in this study. Evaluated agrotechnical measures, i.e. depth of pruning, term of pruning and number of trained bines, considerably influenced performance and quality of newly grown hop genotype. Every year, we found a positive influence of shallow pruning on yield (increase of dry hop cones yield in 2003 by 0.37 t/ha, in 2004 by 0.28 t/ha and in 2005 by 0.02 t/ha). The hop yield of plants treated with shallow pruning increased on average by 11.6% in three years. We proved a statistically significant influence of three-bines training system on one hop pole, i.e. 3 + 3 bines from each plant. We found that alpha-bitter acids content corresponds with cones yield and indicates a convenience of shallow pruning. Pruning term influenced alpha-bitter acids yield and dynamics of their formation (in the first pruning term yield it was 155 kg/ha, in the second pruning term it was 169 kg/ha, and in the third pruning term it was 175 kg/ha).

Abstract Commercial production from a guava orchard begins on the third year after planting and cropping may continue for 40 years or more. The performance of an orchard depends on its management, which includes water and nutrient management, selection of the correct cultivars, planting technique, canopy management for flowering and fruiting, and improved light efficiency through pruning to optimize the quality of young and bearing trees. This chapter provides information on planting system, planting density, training and pruning, intercropping, and weed control in guava orchards.

Abstract This paper explores linguistic egocentrism in English through the lens of virtual performatives, i.e. self-referential stand-alone predications in the third person singular present tense through which users perform virtual action or emotion. The focus is on microblogging for apparently recreational purposes, where visibility, rather than reciprocity, must be a primary concern. Findings show that the common or garden virtual performative consistently relying on an externalized self occasionally turns into a variant where the self is subsequently reassumed, and then again possibly re-externalized within the same construction. The syntactic and discursive systematicity manifest in these constructions forbids treating them as erroneous. The paper discusses the benefits of this way of externalizing and optionally reassuming self, through fluctuation between third-person and first-person references, and touches upon metapragmatic awareness and logophoricity. In creating digital culture, virtual performatives point to users’ pragmatic adaptation of their public, social self to environments manifesting a high degree of context collapse.

This chapter centers on US feminists’ objections to the fact that a man, Mexican Attorney General Pedro Ojeda Paullada, presided over the IWY intergovernmental conference. Those more familiar with UN protocols pointed to the common practice of having the head of the host country’s delegation preside over thematic conferences, and many participants from around the world applauded the idea that men also should be concerned about women’s status. Those objecting to Ojeda Paullada’s presidency coalesced into the self-styled Feminist Caucus. The episode raised issues about which strands of feminism enjoyed legitimacy in different contexts and whether women needed separate spaces to deliberate without involvement by men.

Chapter four critically reviews the anti-capitalist literature on the commons, comprising of various interpretations of Marx’s work, among others. The first section investigates the relation of the political and the common in a broad spectrum of continental political philosophy, including ‘post-hegemony’ notably Ernesto Laclau and Chantal Mouffe and the autonomous Marxist tradition (Michael Hardt and Toni Negri) in the context of Alexandros Kioupkiolis’s critique who points to the crowding out of the self-instituting power of the people in several Marxist and post-Marxist interpretations of the common. The second section focuses on the work of Pierre Dardot and Christian Laval who have reintroduced the self-instituting power of the people in political discourse as the essential concept of ‘the common’. The third section illustrates a more concrete version of the common, articulated in the Katharine Gibson and Julie Graham’s work, who sketch out the philosophical and empirical preconditions of a community economy. The fourth section deals with the concept of the common as the self-instituting power of the people to introduce variants of autonomous Marxism, ranging from post-capitalism to anti-capitalism. Lastly, the fifth section examines the conception of the common in the context of autonomous and classical Marxist views . Authors discussed include Nick Dyer-Witheford, Massimo De Angelis, George Caffentzis, Silvia Federici, Slavoj Žižek, Jodi Dean, David Harvey, Paul Mason and Christian Fuchs. The author concludes that a set of policies could be integrated into a holistic, post-hegemonic strategy for a post-capitalist, com­mons-orientated transition drawing also on some reformist perspectives.

Purpose The purpose of this study was to identify levels of self-compassion in adults who do and do not stutter and to determine whether self-compassion predicts the impact of stuttering on quality of life in adults who stutter. Method Participants included 140 adults who do and do not stutter matched for age and gender. All participants completed the Self-Compassion Scale. Adults who stutter also completed the Overall Assessment of the Speaker's Experience of Stuttering. Data were analyzed for self-compassion differences between and within adults who do and do not stutter and to predict self-compassion on quality of life in adults who stutter. Results Adults who do and do not stutter exhibited no significant differences in total self-compassion, regardless of participant gender. A simple linear regression of the total self-compassion score and total Overall Assessment of the Speaker's Experience of Stuttering score showed a significant, negative linear relationship of self-compassion predicting the impact of stuttering on quality of life. Conclusions Data suggest that higher levels of self-kindness, mindfulness, and social connectedness (i.e., self-compassion) are related to reduced negative reactions to stuttering, an increased participation in daily communication situations, and an improved overall quality of life. Future research should replicate current findings and identify moderators of the self-compassion–quality of life relationship.

Purpose: This study aimed to translate and culturally adapt the self-report and parent-proxy Health-Related Quality of Life Measure for Children with Epilepsy (CHEQOL-25) into Vietnamese and to evaluate their reliability. Methods: Both English versions of the self-report and parent-proxy CHEQOL-25 were translated and culturally adapted into Vietnamese by using the Principles of Good Practice for the Translation and Cultural Adaptation Process. The Vietnamese versions were scored by 77 epileptic patients, who aged 8–15 years, and their parents/caregivers at neurology outpatient clinic of Children Hospital No. 2 – Ho Chi Minh City. Reliability of the questionnaires was determined by using Cronbach’s coefficient α and intra-class correlation coefficient (ICC). Results: Both Vietnamese versions of the self-report and parent-proxy CHEQOL-25 were shown to be consistent with the English ones, easy to understand for Vietnamese children and parents. Thus, no further modification was required. Cronbach’s α coefficient for each subscale of the Vietnamese version of the self-report and parent-proxy CHEQOL-25 was 0.65 to 0.86 and 0.83 to 0.86, respectively. The ICC for each subscale of the self-report and parent-proxy CHEQOL-25 was in the range of 0.61 to 0.86 and 0.77 to 0.98, respectively. Conclusion: The Vietnamese version of the self-report and parent-proxy CHEQOL-25 were the first questionnaires about quality of life of epileptic children in Vietnam. This Vietnamese version was shown to be reliable to assess the quality of life of children with epilepsy aged 8–15 years.
