The vegetation in the latter stages of an active mud slump of known age on Garry Island, Mackenzie River Delta, N.W.T., is described using principal-component analysis. Three associations are recognized. Senecio congestus and isolated hummocks with dwarf shrub – heath vegetation dominate during the first 4 years after exposure. The Arctagrostis latifolia – Senecio congestus association that dominates after 4 years represents the second stage of development after the disappearance of recognizable hummocks. The Arctagrostis latifolia – Eriophorum scheuchzeri association that dominates after 6 years is the third stage in the revegetation sequence and represents further stabilization of the mud slump surface. The frequency of hummock-associated species is greatly reduced. The rapid rate of natural revegetation, in such a mud slump where the headwall had been receding, would suggest that man-induced reseeding programs, in all probability, would not speed up the process.

Colour Terms

In this paper, the author compares chromatic terms in Ruthenian and Serbian. He focuses on the basic colour terms according to Berlin and Kay: white, black, red, green, yellow, blue, brown, purple, pink, orange, and grey. They have equivalents in both languages: Ruthenian bila – Serbian bela, čarna – crna, červena – crvena, željena – zelena, žovta / žolta – žuta, belava – plava, braon – braon, lilova – ljubičasta, celova – roze, pomarančecova /poma- randžecova – narandžasta, šiva – siva. The criterion of one-morpheme word is not appli- cable to the terms lilova, celova, and pomarančecova /pomarandžecova in Ruthenian, and ljubičasta and narandžasta in Serbian. It is applicable to the terms bila, čarna, červena, željena, žovta / žolta, belava, braon, and šiva. With the exception of braon, all these terms are derived from the Proto-Slavic language (*bеlъ, *čьrnъ, *čьrvenъ, *zelenъ, *žltъ, *polvь, and *sivъ). As far as the Berlin–Kay’s universal of seven phases of colour formation is con- cerned, our study of chromatic terminology confirms it. In accordance with the supposed first stage of development, the Ruthenian language has bila and čarna; according to the second stage, Ruthenian has červena; in accordance with the third stage, Ruthenian has že- ljena or žovta / žolta; according to the fourth stage, Ruthenian has žovta / žolta or željena; in accordance with the fifth stage, Ruthenian has belava; according to the sixth stage, it has braon; and in accordance with the seventh stage (even if we leave aside the multi-mor- pheme terms lilova, celova, and pomarančecova /pomarandžecova), it has šiva. Generally speaking, the usage of the terms is identical in both investigated languages but there are several differences (e.g. cibulja – beli luk, željena pasulja – boranija). The most frequent suffixes are -asta and -ista in Ruthenian, and -asta in Serbian.Most of the chromatic terms are of Slavic origin but there are several borrowings used for nuance purposes in recent decades, e.g. azurna, teget, akvamarin, tirkizna, and others. Some borrowings remain unchanged, e.g. in both languages blond, braon, drap, krem, bež, and oker, and only in Serbian lila and roze. Hungarian was the official language until the first decades of the 20th century (until the collapse of the Austro-Hungarian Monarchy in 1918), during which Ruthenian–Hungarian bilingualism reigned. That is the reason why several Hungarian colour names are found, e.g. in surnames (the Ruthenian surname Barna comes from Hungarian barna ‘brown’, Fekete/Feketa is from fekete ‘black’, and Vereš is from vörös ‘red’) and in the names of domestic animals (the Ruthenian horse name pejka [Serbian riđan] comes from Hungarian pej ‘brown’ and šarga [Serbian žutalj] is from sár- ga ‘yellow’). The general name for ‘colour’ comes from the German language (Ruthenian farba is from German Farbe).

Plants introduced by man play a very minor role in the flora of the Mackenzie River, delta and are primarily restricted to centres of habitation such as Inuvik, Aklavik, and Reindeer Station (Map 1) (Cody, 1965; Gill, 1971). Within the delta itself, however, a number of introduced species are recurringly present on one geomorphic position, the point bar, which forms the convex section of a meander bend in flood plains and deltas (Fig 1). The Mackenzie delta supports a northerly extension of the boreal forest, and most of the higher levees are occupied by trees, particularly White Spruce Picea glauca. Point bars are constructed of coarser alluvium than other delta landforms, thus they have a drier and warmer soil environment than other locations (Gill, 1972a); vegetation response to this locally ameliorated environment has been such that virtually every point bar in the Mackenzie delta is occupied by a discrete plant community dominated by Balsam Poplar Populus balsamifera (Gill, 1972b). The poplar stands are surprisingly well developed for such a northerly latitude, 68°45′N (Fig 2).

Since the beginning of utilization of the lean production concept it has passed several stages of implementation. The first stage failed because manufacturers that introduced lean production methods were isolated from each other; whereas in the second stage, these companies learned from their experiences. Since then, the lean production concept has been used to organize production and reduce costs, despite the fact that markets are becoming more demanding due to individualization of demand and variability of conditions. Digitalization suggests methods for adapting the concept of lean production to such a market indicator as company performance. Thus, the utilization of the concept “Industry 4.0” can initiate the third stage of development of the practice of lean manufacturing in terms of analyzing the productivity from a multidimensional point of view.

Recent Epoch

In the recent epoch the Kuban River delta is characterized by little distributary with low zone of lagoons and flooded areas. This accumulative plain includes different types of mesorelief such as longshore bar, channel bank, liman, plavni and channel distributaries. There are three huge geomorphological types of Kuban delta: old, young deltas and Kuban-Taman region. The main differences between them are diverse geomorphological levels, evolution of marine and fluvial forms and incomplete geomorphological development. The relief of the Kuban delta is Holocene. The main factors of its formation were large-scale fluctuations of the Azov-Black Sea basin, the flow of water and sediment of the Kuban River and its distribution in area. In the history of the development of the modern relief of the Kuban delta, there are three stages (epochs). The first is the Bugaz stage of the Holocene transgression (9.57.9 ka), when the relief of the old delta was formed. In the second stage of the Holocene transgression (Vityazevskaya, Kalamitskaya, and Dzhemetyan stages), a transitional type of relief was formed in the area adjacent to the floods of the young delta and the old delta with the formation of large buried bars. In the third stage, the systems of modern estuaries and plavni were formed, separated from the sea by a modern coastal bar.

Speed Up

A relatively new entry, in the field of microscopy, is the Scanning X-Ray Fluorescence Microscope (SXRFM). Using this type of instrument (e.g. Kevex Omicron X-ray Microprobe), one can obtain multiple elemental x-ray images, from the analysis of materials which show heterogeneity. The SXRFM obtains images by collimating an x-ray beam (e.g. 100 μm diameter), and then scanning the sample with a high-speed x-y stage. To speed up the image acquisition, data is acquired "on-the-fly" by slew-scanning the stage along the x-axis, like a TV or SEM scan. To reduce the overhead from "fly-back," the images can be acquired by bi-directional scanning of the x-axis. This results in very little overhead with the re-positioning of the sample stage. The image acquisition rate is dominated by the x-ray acquisition rate. Therefore, the total x-ray image acquisition rate, using the SXRFM, is very comparable to an SEM. Although the x-ray spatial resolution of the SXRFM is worse than an SEM (say 100 vs. 2 μm), there are several other advantages.

Mode Of Production

Critics have argued that Elizabeth Gaskell's first novel, Mary Barton (1848), is split by a conflict between the modes of realism and romance. But the conflict does not render the novel incoherent, because Gaskell surpasses both modes through a utopian narrative that breaks with the conflict of form and gives coherence to the whole novel. Gaskell not only depicts what Thomas Carlyle called the ‘Condition of England’ in her work but also develops, through three stages, the utopia that will redeem this condition. The first stage is romantic nostalgia, a backward glance at Eden from the countryside surrounding Manchester. The second stage occurs in Manchester, as Gaskell mixes romance with a realistic mode, tracing a utopian drive toward death. The third stage is the utopian break with romantic and realistic accounts of the Condition of England and with the inadequate preceding conceptions of utopia. This third stage transforms narrative modes and figures a new mode of production.

The first stage of this project aims to identify assessment measures which include items on voice-hearing by way of a systematic review. The second stage is the development of a brief framework of categories of positive experiences of voice hearing, using a triangulated approach, drawing on views from both professionals and people with lived experience. The third stage will involve using the framework to identify any positve aspects of voice-hearing included in the voice hearing assessments identified in stage 1.

Intentional Structure

The existential crisis of nihilism in schizophrenia has been reported since the early days of psychiatry. Taking first-person accounts concerning nihilistic experiences of both the self and the world as vantage point, we aim to develop a dynamic existential model of the pathological development of existential nihilism. Since the phenomenology of such a crisis is intrinsically subjective, we especially take the immediate and pre-reflective first-person perspective’s (FPP) experience (instead of objectified symptoms and diagnoses) of schizophrenia into consideration. The hereby developed existential model consists of 3 conceptualized stages that are nested into each other, which defines what we mean by existential. At the same time, the model intrinsically converges with the phenomenological concept of the self-world structure notable inside our existential framework. Regarding the 3 individual stages, we suggest that the onset or first stage of nihilistic pathogenesis is reflected by phenomenological solipsism, that is, a general disruption of the FPP experience. Paradigmatically, this initial disruption contains the well-known crisis of common sense in schizophrenia. The following second stage of epistemological solipsism negatively affects all possible perspectives of experience, that is, the first-, second-, and third-person perspectives of subjectivity. Therefore, within the second stage, solipsism expands from a disruption of immediate and pre-reflective experience (first stage) to a disruption of reflective experience and principal knowledge (second stage), as mirrored in abnormal epistemological limitations of principal knowledge. Finally, the experience of the annihilation of healthy self-consciousness into the ultimate collapse of the individual’s existence defines the third stage. The schizophrenic individual consequently loses her/his vital experience since the intentional structure of consciousness including any sense of reality breaks down. Such a descriptive-interpretative existential model of nihilism in schizophrenia may ultimately serve as input for future psychopathological investigations of nihilism in general, including, for instance, its manifestation in depression.

The Village

In Mesoamerica and the Near East, the emergence of the village seems to have involved two stages. In the first stage, individuals were distributed through a series of small circular-to-oval structures, accompanied by communal or “shared” storage features. In the second stage, nuclear families occupied substantial rectangular houses with private storage rooms. Over the last 30 years a wealth of data from the Near East, Egypt, the Trans-Caucasus, India, Africa, and the Southwest U.S. have enriched our understanding of this phenomenon. And in Mesoamerica and the Near East, evidence suggests that nuclear family households eventually gave way to a third stage, one featuring extended family households whose greater labor force made possible extensive multifaceted economies.

AbstractThis article investigates an effective method with which to reconstruct the tragus and external auditory meatus for microtia reconstruction. The external ear was reconstructed using a delayed postauricular skin flap in patients with congenital microtia. After the first stage of delaying the postauricular skin flap and the second stage of otoplasty with ear framework fabricated from autogenous rib cartilage draping with the delayed skin flap, the third stage involved tragus and external auditory meatus canaloplasty. After designing the remnant auricle flap, the lower part was trimmed and the tragus was reconstructed. The upper part was trimmed into a thin skin flap, which was rotated and used to cover the hollowed wound posterosuperior to the tragus so as to mimic the external auditory meatus. If remnant wounds were present, skin grafting was conducted. In total, 121 patients with congenital microtia were treated from March 2010 to March 2016. The reconstructed tragus and external auditory meatus were well formed, and all wounds healed well. No severe complications such as flap necrosis occurred. Six months postoperatively, the morphology of the reconstructed tragus and external auditory meatus was good. Overall, the patients and their families were satisfied. The use of remnant auricle to reconstruct the tragus and external auditory meatus is an effective auricular reconstruction technique.
